  NTL Incorporated, a Delaware corporation (the "Company"), hereby offers, upon
the terms and subject to the conditions set forth in this Prospectus and the
accompanying Letter of Transmittal (which together constitute the "Exchange
Offer"), to exchange (i) an aggregate principal amount of up to
(Pounds)125,000,000 9 1/2% Series B Senior Notes Due 2008 of the Company (the
"New Sterling Senior Notes"), for a like principal amount of the issued and
outstanding 9 1/2% Senior Notes Due 2008 of the Company (the "Old Sterling
Senior Notes" and, together with the New Sterling Senior Notes, the "Sterling
Senior Notes"), (ii) an aggregate principal amount at maturity of up to
(Pounds)300,000,000 10 3/4% Series B Senior Deferred Coupon Notes Due 2008 of
the Company (the "New Sterling Deferred Coupon Notes"), for a like principal
amount at maturity of the issued and outstanding 10 3/4% Senior Deferred Coupon
Notes Due 2008 of the Company (the "Old Sterling Deferred Coupon Notes" and,
together with the New Sterling Deferred Coupon Notes, the "Sterling Deferred
Coupon Notes"), and (iii) an aggregate principal amount at maturity of up to
$1,300,000,000 9 3/4% Series B Senior Deferred Coupon Notes Due 2008 of the
Company (the "New USD Deferred Coupon Notes", and together with the New
Sterling Senior Notes and the New Sterling Deferred Coupon Notes, the "New
Notes"), for a like principal amount at maturity of the issued and outstanding
9 3/4% Senior Deferred Coupon Notes Due 2008 (the "Old USD Deferred Coupon
Notes", and, together with the New USD Deferred Coupon Notes, the "USD Deferred
Coupon Notes" and, together with the Old Sterling Senior Notes and the Old
Sterling Deferred Coupon Notes, the "Old Notes" and, the Old Notes, together
with the New Notes, the "Notes"), in each case, from the respective holders
thereof (the "Holders"). The terms of the New Notes are identical in all
material respects to the Old Notes except for certain transfer restrictions and
registration rights relating to the Old Notes and except for certain provisions
providing for special interest on the Old Notes under certain circumstances
relating to the timing of the Exchange Offer.
 
  On March 13, 1998 the Company issued (Pounds)125,000,000 aggregate principal
amount of Old Sterling Senior Notes, (Pounds)300,000,000 aggregate principal
amount at maturity of Old Sterling Deferred Coupon Notes, and $1,300,000,000
aggregate principal amount at maturity of Old USD Deferred Coupon Notes. The
Old Notes were issued pursuant to an offering exempt from registration under
the Securities Act of 1933, as amended (the "Securities Act") and applicable
state securities laws.
 
  The Old Notes are, and the New Notes will be, senior unsecured obligations of
the Company, ranking pari passu in right of payment of principal, premium, if
any, and interest with all other existing and future unsubordinated obligations
of the Company and ranking senior to all other existing and future subordinated
debt of the Company. The Company is a holding company and, therefore, the Old
Notes are, and the New Notes will be, effectively subordinated to all existing
and future indebtedness and other liabilities and commitments of the Company's
subsidiaries with respect to the cash flow and assets of those subsidiaries. As
of March 31, 1998, such subsidiaries had approximately $342 million
((Pounds)205 million) of total liabilities.
 
  The New Sterling Senior Notes will bear interest from the most recent date to
which interest has been paid on the Old Sterling Senior Notes or, if no
interest has been paid on the Old Sterling Senior Notes, from March 13, 1998.
Accordingly, if the relevant record date for interest payment occurs after the
consummation of the Exchange Offer, registered holders of New Sterling Senior
Notes on such record date will receive interest accruing from the most recent
date to which interest has been paid or, if no interest has been paid, from
March 13, 1998. If, however, the relevant record date for interest payment
occurs prior to the consummation of the Exchange Offer, registered holders of
Old Sterling Senior Notes on such record date will receive interest accruing
from the most recent date to which interest has been paid or, if no interest
has been paid,
 
                                                           (continued on page 2)
 
  SEE "RISK FACTORS" ON PAGE 18 OF THIS PROSPECTUS FOR A DESCRIPTION OF CERTAIN
RISKS TO BE CONSIDERED BY HOLDERS WHO TENDER THEIR OLD NOTES IN THE EXCHANGE
OFFER.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.
 
                  The date of this Prospectus is      , 1998.

(continued from front cover page)
 
from March 13, 1998. Old Sterling Senior Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
Exchange Offer, except as set forth in the immediately preceding sentence.
Holders of Old Sterling Senior Notes whose Old Sterling Senior Notes are
accepted for exchange will not receive any payment in respect of interest on
such Old Sterling Senior Notes otherwise payable on any interest payment date
the record date for which occurs on or after consummation of the Exchange
Offer. The Old Sterling Deferred Coupon Notes and the Old USD Deferred Coupon
Notes were issued at a substantial discount from their principal amount at
maturity. Cash interest will not accrue on the New Sterling Deferred Coupon
Notes and the New USD Deferred Coupon Notes prior to April 1, 2003. Commencing
April 1, 2003, interest on the New Sterling Deferred Coupon Notes and the New
USD Deferred Coupon Notes will accrue at rates of 10.75% and 9.75%,
respectively, and will be payable semiannually in arrears on each April 1 and
October 1, commencing October 1, 2003. Original issue discount on the New
Sterling Deferred Coupon Notes and the New USD Deferred Coupon Notes will
accrue from March 13, 1998, the date of original issuance of the Old Sterling
Deferred Coupon Notes and the Old USD Deferred Coupon Notes, respectively.
 
  The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreements (as
defined). Based on interpretations of the staff of the Securities and Exchange
Commission (the "Commission"), as set forth in no-action letters issued to
third parties, the Company believes that the New Notes issued pursuant to the
Exchange Offer in exchange for the Old Notes may be offered for resale, resold
and otherwise transferred by Holders thereof (other than any such Holder which
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such New Notes are
acquired in the ordinary course of such Holders' business and such Holders
have no arrangement or understanding with any person to participate in the
distribution (within the meaning of the Securities Act) of such New Notes. The
Company acknowledges and each Holder, other than a broker-dealer, must
acknowledge that it is not engaged in, does not intend to engage in, and has
no arrangement or understanding with any person to participate in the
distribution of New Notes. If any Holder is an affiliate of the Company, is
engaged in or intends to engage in or has any arrangement or understanding
with any person to participate in the distribution of the New Notes to be
acquired pursuant to the Exchange Offer, such Holder (i) could not rely on the
applicable interpretations of the staff of the Commission and (ii) must comply
with the registration and prospectus delivery requirements of the Securities
Act in connection with any resale transaction. Each broker-dealer who holds
Old Notes acquired for its own account as a result of market-making activities
or other trading activities, and who receives New Notes in exchange for such
Old Notes pursuant to the Exchange Offer, may be an "underwriter" within the
meaning of the Securities Act and must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resale of such New Notes. The Letter of Transmittal states that by so
acknowledging 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. 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 by
such broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, starting on the Expiration Date (as
defined) and ending at the close of business on the 180th day following the
Expiration Date it will make this Prospectus available to any broker-dealer
for use in connection with any such resale. See "Plan of Distribution."
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all of the expenses incident to the Exchange Offer. Tenders
of Old Notes pursuant to the Exchange Offer may be withdrawn at any time prior
to the Expiration Date. If the Company terminates the Exchange Offer and does
not accept for exchange any Old Notes, the Company will promptly return Old
Notes to the Holders thereof. See "The Exchange Offer."
 
  The Old Notes are eligible for trading in the Private Offerings, Resales and
Trading through Automated Linkages ("PORTAL") market and are listed on the
Luxembourg Stock Exchange. Prior to this Exchange Offer, there has been no
public market for the New Notes. Although the Initial Purchasers (as defined)
have informed the Company that they intend to make a market in the New Notes,
they are not obligated to do so and any such market-making may be discontinued
at any time without notice. If a market for the New Notes should develop, the
New Notes could trade at a discount from their principal amount or Accreted
Value (as defined), as the case may be. The Company does not currently intend
to list the New Notes on any securities exchange (other than the Luxembourg
Stock Exchange) or to seek approval for quotations through any automated
quotation systems. There can be no assurance that a market for the New Notes
will develop.

  UNTIL        1998 (90 DAYS AFTER THE DATE OF THIS PROSPECTUS) DEALERS
AFFECTING TRANSACTIONS IN THE NEW NOTES, WHETHER OR NOT PARTICIPATING IN THE
EXCHANGE OFFER, MAY BE REQUIRED TO DELIVER A PROSPECTUS. THIS OBLIGATION IS IN
ADDITION TO THE OBLIGATION OF DEALERS TO DELIVER A PROSPECTUS WHEN ACTING AS
UNDERWRITERS AND WITH RESPECT TO THEIR UNSOLD ALLOTMENTS OR SUBSCRIPTIONS.

                                  THE COMPANY
 
  NTL is a leading communications company in the United Kingdom, providing
residential, business and wholesale customers with the following services: (i)
Residential Telecoms and Television Services including residential telephony,
cable television and Internet access services, (ii) National Telecoms Services
including national business telecoms, national and international carrier
telecommunications, and satellite and radio communications services, and (iii)
Broadcast Services including digital and analog television and radio broadcast
transmission services.
 
  NTL provides its broad range of services over local, national and
international network infrastructure. The Company operates: (i) advanced local
broadband networks serving entire communities throughout NTL's regional
franchise areas, (ii) the UK's first synchronous digital hierarchy ("SDH")
backbone telecommunications network, as well as satellite earth stations and
radio communications facilities from NTL's tower sites across the UK, and (iii)
a broadcast transmission network which provides national, regional and local
analog and digital transmission services to customers throughout the UK.
 
  In March 1997, the Company changed its name from International CableTel
Incorporated to NTL Incorporated to reflect the integration of the services
provided by the Company following its acquisition of NTL Group Limited in 1996,
and to capitalize on NTL Group Limited's 30 year history in the United Kingdom
as a provider of reliable communications services.
 
RESIDENTIAL TELECOMS AND TELEVISION SERVICES
 
  The Company is the third largest operator of local broadband communications
systems in the UK as measured by the number of homes in its franchise areas,
and has achieved the highest customer penetration and lowest churn rates of any
multi-system operator in the UK. The Company is presently the sole provider of
broadband services in its franchise areas, offering residential telephony,
cable television and Internet access services to customers connected to its
networks.
 
  As of March 31, 1998, the Company had 357,200 residential customers,
approximately 90% of which subscribed to both telephone and television
services. As of March 31, 1998 the Company had a total of 679,700 Revenue
Generating Units ("RGUs") resulting in 38.1% telephone penetration, 38.5% cable
penetration and 76.6% RGU penetration of homes marketed. By comparison, based
on published statistics of the Independent Television Commission ("ITC"), dated
March 9, 1998, as of January 1, 1998, UK cable customer
penetration averaged approximately 28.0% for telephone and approximately 22.2%
for cable television. As of January 1, 1998, the UK telephony cable industry
had connected approximately 3.4 million telephone lines and approximately 2.4
million broadband cable customers.

- --------
(1) "Homes passed" is the expression in common usage in the cable industry as
    the measurement of the size of a cabled area, meaning the total number of
    residential premises which have the potential to be connected to the
    Company's network.
(2) As of March 31, 1998, the Company also provided service to approximately
    35,400 customers connected to acquired cable systems over which it does not
    offer a full range of services.
(3) An RGU (revenue generating unit) is one telephone account or one CATV
    account; a dual customer represents two RGUs.
(4) RGU penetration is the number of RGUs per 100 homes marketed. As defined,
    maximum RGU penetration is 200%.
NM Not meaningful due to the limited customer base and recent commencement of
   services.
 
  The Company's customer base and RGUs both increased by nearly 100% in 1997
compared to year-end 1996. The Company believes that much of its success during
this period has been due to its marketing strategies and the introduction of
innovative residential services packages which bundle telephone and a small
selection of CATV channels within a single product offering. The Company also
gives customers the opportunity to purchase additional channel packages and
premium channels. Consistent with the Company's objectives, the high
penetration rates generated by this strategy have led to increased levels of
gross profit contribution per home passed.
 
  The Company believes it has also maintained high levels of customer
satisfaction as indicated by the Company's low rates of churn. During 1997, the
Company maintained an annualized churn rate of less than 11%, a rate which is
significantly lower than the published churn rates of all other UK telephony
cable operators. In a recent survey of a sample of its customers, NTL found
that 89% of its customers would recommend the service to a friend or relative,
and that only 15% had ever considered changing their telephone service back to
British Telecommunications plc ("BT").
 
  NTL's local franchise areas cover approximately 2.1 million homes, spanning a
wide geography across England, Scotland, Wales and Northern Ireland. As of
March 31, 1998, the Company's integrated full-service network had been
constructed past over one million (or approximately 51%) of its homes under
franchise. NTL's local broadband networks use advanced high capacity SDH fiber
rings which serve entire communities, bringing fiber connections directly to
businesses and "Siamese" coaxial/copper connections to residences. The
Company's local networks cover approximately 2,500 route miles of fiber
backbone network, with approximately 175,000 fiber miles, and an estimated
5,000 route miles of "Siamese" coaxial/copper connections.
 
NATIONAL TELECOMS SERVICES
 
  The Company's objective in National Telecoms Services is to successfully
integrate its strategies for developing, operating and marketing local
telephony/cable systems with its national network to provide high-
quality voice, data and video communications services throughout the UK. The
Company has constructed a national SDH fiber telecoms network, which is one of
only five national telecoms networks in the UK. The NTL
 
                                       7
<PAGE>
 
national network currently covers approximately 1,500 route miles and 40,000
fiber miles throughout England, Scotland and Wales. During 1998, the Company
plans to extend the network to include the first resilient fiber connection
between Northern Ireland, the Republic of Ireland and England.
 
  The integration of its local networks with the national telecoms network
creates strategic advantages for the Company's telephony business. The national
network allows the Company to carry telecommunications traffic between each of
its franchise areas and throughout the United Kingdom and, therefore, achieve
significant savings on the interconnection fees it pays to other carriers. In
addition, using the national telecoms network gives the Company greater pricing
flexibility and will enable the Company to design and offer new telephony
services packages to its customers, which management believes should have a
positive effect on the Company's penetration rates.
 
  Capitalizing on the extended reach of its national network, the Company is
competing for a share of the approximately (Pounds)21 billion UK telecoms
market on a national basis. In the business telecoms market, the Company has
been increasingly successful in obtaining telecoms contracts from businesses
located within its franchise areas. As of March 31, 1998, the Company had a
total of approximately 8,100 business customers, which represented growth in
the quarter of approximately 23%. The Company's current business customers
include major international corporations, universities, local governmental
authorities, and small and medium sized businesses. Management believes that it
can build on the strengths gained in its local franchise areas to approach
targeted business users located in other areas of the UK. To connect the "last
mile" to the customers' premises from the national network, NTL has a variety
of options, including building fiber where justified, using microwave links
from the NTL tower infrastructure, or leasing circuits from other local
operators. NTL launched its national business telecoms service in November 1997
and its strategy is to target medium to large businesses, beginning with those
located near the major urban areas currently served by the NTL national
network.
 
  The Company also offers a variety of other telecommunications services from
its national fiber network and microwave transmission facilities. NTL competes
in the growing market for bandwidth and leased line services as a national and
international wholesale telecommunications carrier. The Company's international
facilities license allows it to carry international traffic, and NTL has
recently entered into an agreement for a 25 year lease of international
telecommunications capacity on a new transatlantic fiber optic cable connecting
The Netherlands, Germany, the UK and the United States. NTL is also expanding
its product portfolio to include virtual private networks, managed data
networks, ATM and frame relay services and multi-media services.
 
  In addition to business and carrier telecoms, the Company provides the
following telecom services: (i) a full range of services in the design,
building and operation of radio based networks, and the provision of
infrastructure and support services to customers in the emergency services
sector, (ii) global satellite connectivity for clients requiring video, digital
audio and data services, and (iii) residential, wholesale and business Internet
access and support services, consulting and systems integration services, and
Intranet design and implementation.
 
BROADCAST SERVICES
 
  The Company's Broadcast Services group includes the original core business of
NTL Group Limited which has been providing television and radio broadcasters
with broadcast transmission services for more than 30 years.
 
  NTL transmits television and radio broadcast signals for the UK's main
commercial television channels and independent radio stations from a national
infrastructure of over 1,200 owned and shared transmission sites
across the UK. Current customers include the Independent Television ("ITV" or
"Channel 3") companies, Channel 4 and the Welsh Fourth Channel ("S4C"), and
Channel 5. Other customers include Teletext and many of the United Kingdom's
independent local, regional and national radio broadcasters. The Broadcast
Services group provides the Company with a stable contracted revenue stream
from a variety of customers, through long-term contracts generally with eight
to ten year terms. In addition to transmission services, the Broadcast Services
 
                                       8
<PAGE>
 
group markets value added services to its existing television customers. This
group also designs, installs, operates and maintains new transmitter networks
and has a spectrum planning service to plan the coverage of television and
radio networks.
 
  Two of the four recipients of the Digital Terrestrial Television ("DTT")
multiplexes awarded to date have selected the Company as the preferred supplier
of transmission services. If the Company successfully concludes contractual
arrangements with the multiplex operators, the introduction of DTT broadcasting
in the UK will significantly expand the Company's broadcasting transmission
services business.
 
  The Company, a Delaware corporation, was incorporated on April 2, 1993. The
Company is a holding company and conducts its operations through direct and
indirect wholly owned subsidiaries. The Company is not a subsidiary of any
other company. The Company's principal executive office is located at 110 East
59th Street, New York, New York 10022, and its telephone number is (212) 906-
8440.
 
                               RECENT DEVELOPMENT
 
PROPOSED PARTNERS ACQUISITION
 
  General. On February 4, 1998, the Company and NTL (Bermuda) Limited, a
Bermuda corporation and a wholly owned subsidiary of NTL ("Sub") entered into
an Agreement and Plan of Amalgamation as amended, (the "Amalgamation
Agreement") with Comcast UK Cable Partners Limited ("Partners") which provides
for the amalgamation of Sub with Partners (the "Amalgamation"), with the
separate existence of Sub and Partners continuing in the form of the company
resulting from the Amalgamation. The form and amount of consideration payable
to Partners' shareholders in the Amalgamation is dependent upon the timing of
the procedures related to certain purchase rights with respect to Partners'
interests in Birmingham Cable Corporation Limited ("Birmingham Cable") and
Cable London PLC ("Cable London") described below, whether or not such purchase
rights are ultimately exercised and, if exercised, the net after-tax proceeds
received by Partners as a result of the exercise of either or both of such
purchase rights. The maximum consideration payable to Partners' shareholders is
0.3745 shares of the Company's Common Stock for each Partner's Class A Common
Share or Class B Common Share. For more information concerning the
Amalgamation, see the Amalgamation Agreement, a copy of which has been filed
with the Commission as an exhibit to the Company's Form 8-K dated February 5,
1998, which is incorporated by reference into this Prospectus. See
"Incorporation of Certain Documents By Reference." Consummation of the
Amalgamation is subject to a number of closing conditions including regulatory
approvals, shareholder approval by the Company and Partners and consents from
their respective banks and bondholders.
 
  Partners. Partners, an indirect controlled subsidiary of Comcast Corporation
("Comcast") was incorporated in 1992 to develop, construct manage and operate
the interests of Comcast in the UK cable and telecommunications industry. As of
March 31, 1998, Partners had interests in four operations (the "Partners
Operating Companies"): Birmingham Cable, in which Partners owns a 27.5%
interest, Cable London, in which Partners owns a 50.0% interest, Cambridge
Holding Company Limited, in which Partners owns a 100% interest and two
companies holding the franchises for Darlington and Teesside, England, in which
Partners owns a 100% interest.
 
  The Partners Operating Companies' systems are reported to have the potential
to serve approximately 1.6 million homes and the businesses within their
franchise areas when their build-out is complete. As of December 31, 1997,
Partners reported that the Partners Operating Companies' systems passed more
than 1,197,000 homes or approximately 75% of the homes in their franchise
areas, and served more than 298,000 cable subscribers, 359,000 residential
telephony subscribers and 11,000 business telephony subscribers.
 
 
                                       9

  Purchase Rights Relating to Partners' Interests in Birmingham Cable and Cable
London. As a result of the proposed Amalgamation, TeleWest Communications plc
("TeleWest"), which owns a 27.5% interest in Birmingham Cable and a 50%
interest in Cable London, has certain rights (the "Purchase Rights") to acquire
Partners' 27.5% interest in Birmingham Cable (the "Birmingham Cable Equity
Interest") and Partners' 50% interest in Cable London (the "Cable London Equity
Interest" and, together with the Birmingham Cable Equity Interest, the "Equity
Interests").
 
  Partners and TeleWest are parties to a Co-Ownership Agreement, dated March
12, 1990, as amended and supplemented (the "Co-Ownership Agreement"), which
sets forth certain agreements and arrangements regarding their respective
investments in Birmingham Cable. Under the terms of the Co-Ownership Agreement,
neither Partners nor TeleWest (each, a "Co-Owner") may sell, assign, transfer,
pledge or otherwise dispose of, or encumber, directly or indirectly (including
by virtue of any change in control of such Co-Owner), all or any part of any
shares of capital stock of Birmingham Cable (the "Birmingham Cable Shares")
beneficially owned by such Co-Owner, without first offering the other Co-Owner
the right to purchase the Birmingham Cable Shares that are beneficially owned
by such Co-Owner. Consummation of the Amalgamation will result in a change in
control (as defined in the Co-Ownership Agreement) of Partners and,
accordingly, subject to the terms and conditions of the Co-Ownership Agreement,
TeleWest has the right to acquire the Birmingham Cable Equity Interest. On
February 6, 1998, Partners notified TeleWest of its intent to Transfer (as
defined herein) the Birmingham Cable Equity Interest as a result of the
proposed Amalgamation. This notification triggered TeleWest's right to acquire
the Birmingham Cable Equity Interest, subject to the terms and conditions set
forth in the Co-Ownership Agreement.
 
  Under the terms of Cable London's articles of association, a change of
control of Partners will give rise to a deemed offer by partners, as at the
date of such change in control, of all of its shares of capital stock in Cable
London to TeleWest. Consummation of the Amalgamation will result in a change of
control (as defined in Cable London's articles of association) of Partners and,
accordingly, subject to the provisions of Cable London's articles of
association, TeleWest will have the right to acquire the Cable London Equity
Interest. In contrast to TeleWest's right to acquire the Birmingham Cable
Equity Interest, which has already been triggered, TeleWest's right to acquire
the Cable London Equity Interest will not be triggered until the Amalgamation
has been consummated. Thus, unless there is a negotiated agreement between
Partners and TeleWest prior to such time, there will have been no resolution at
the time of consummation of the Amalgamation (the "Effective Time") of whether
TeleWest will exercise such right.
 
  Effects of the Purchase Rights on the Amalgamation Consideration. The
consideration to be received by shareholders of Partners in the Amalgamation is
dependent upon the timing of the procedures related to each of the Purchase
Rights, whether or not the Purchase Rights are ultimately exercised by TeleWest
and, if exercised, the net after-tax proceeds received by Partners in exchange
for the Birmingham Cable Equity Interest or the Cable London Equity Interest or
both, as the case may be. The consideration to be received by shareholders of
Partners in the Amalgamation will be determined as of the fifth business day
prior to the Effective Time. This determination will be made by the Company,
based in part on the status of the Purchase Rights and in part in the Company's
sole discretion.
 
  On April 16, 1998, TeleWest announced that, subject to the valuations
determined for the Equity Interests and the availability of financing, it
proposed to exercise its rights to acquire the Equity Interests. There can be
no assurances that TeleWest will ultimately exercise its rights to acquire the
Equity Interests.

      CONSEQUENCES OF EXCHANGING OLD NOTES PURSUANT TO THE EXCHANGE OFFER
 
  Based on interpretations by the staff of the Commission in no action letters
issued to third parties, generally holders of Old Notes (other than any holder
who is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) who exchange their Old Notes for New Notes pursuant to the
Exchange Offer may offer such New Notes for resale, resell such New Notes, and
otherwise transfer such New Notes without compliance with the registration and
prospectus delivery provisions of the Securities Act; provided that such New
Notes are acquired in the ordinary course of the holders' business and such
holders, other than brokers-dealers, 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 such New Notes.
 
  Each broker-dealer who holds Old Notes acquired for its own account as a
result of market-making activities or other trading activities, and who
receives New Notes in exchange for such Old Notes pursuant to the Exchange
Offer, may be an "underwriter" within the meaning of the Securities Act and
must acknowledge that it will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of such New Notes. See "Plan
of Distribution."
 
  To comply with the securities laws of certain jurisdictions, it may be
necessary to qualify for sale or register thereunder the New Notes prior to
offering or selling such New Notes. The Company has agreed, pursuant to the
Registration Rights Agreements and subject to certain specified limitations
therein, to register or qualify the New Notes held by broker-dealers for offer
or sale under the securities or blue sky laws of such jurisdictions as any such
holder of such New Notes reasonably requests in writing. Unless the Company is
so requested, the Company does not intend to register or qualify the sale of
the New Notes in any such jurisdictions.
 
  If a Holder of Old Notes does not exchange such Old Notes for New Notes
pursuant to the Exchange Offer, such Old Notes will continue to be subject to
provisions of the applicable Indenture regarding transfer and exchange of the
Old Notes and the restrictions on transfer contained in the legend on the Old
Notes. In general, Old Notes may not be offered or sold unless registered under
the Securities Act, except pursuant to an exemption from, or in a transaction
not subject to, the Securities Act and applicable state securities laws. The
Company does not currently anticipate that it will take any action to register
Old Notes under the Securities Act. See "The Exchange Offer--Consequences of
Failure to Exchange" and "Registration Rights."

each case will terminate upon consummation of the Exchange Offer.

                              October 1, commencing on October 1, 1998. The

                              the New USD Deferred Coupon Notes) will rank
                              senior in right of payment to all subordinated
                              indebtedness of the Company and will rank pari

                              with all existing and future unsubordinated
                              obligations of the Company. As of March 31, 1998,
                              the Company had approximately $2.9 billion of
                              unsubordinated debt outstanding. Such
                              unsubordinated debt includes the Company's New
                              Notes, its 10 7/8% Senior Deferred Coupon Notes

                              the "Existing Notes"). The New Notes will be
                              effectively subordinated to all existing and
                              future indebtedness and other liabilities of the
                              Company's subsidiaries with respect to the cash
                              flow and assets of those subsidiaries. As of
                              March 31, 1998, such subsidiaries had
                              approximately $342 million ((Pounds)205 million)

                              defined)), the Company will be required to make
                              an offer to purchase all of the Notes at 101% of
                              principal amount thereof plus accrued and unpaid

                              repurchase). The Company may not have sufficient
                              funds or the financial resources necessary to
                              satisfy its obligations to repurchase the Notes
                              and other debt that may become repayable upon a

                              the "Indentures") contain covenants relating to,

Original Issue Discount.....  The Old Sterling Deferred Coupon Notes and the

                              March 13, 1998 at an issue price of
                              (Pounds)586.20 per (Pounds)1,000 and $617.24 per
                              $1,000 principal amount at maturity,
                              respectively. Each of the New Sterling Deferred

                              income tax purposes. Thus, although cash interest
                              will not accrue on the Sterling Deferred Coupon
                              Notes or the USD Deferred Coupon Notes prior to

                              Notes or the USD Deferred Coupon Notes, as the
                              case may be, and the issue price of the Sterling

                              issue date of the Old Sterling Deferred Coupon
                              Notes or the Old USD Deferred Coupon Notes, as

                              income periodically (including for periods ending
                              prior to October 1, 2003) in a holder's gross
                              income for United States federal income tax
                              purposes in advance of receipt of the cash
                              payments to which the income is attributable. See
                              "Certain Federal Income Tax Considerations."
 
Registration Rights.........  Holders of New Notes (other than as set forth
                              below) are not entitled to any registration
                              rights with respect to the New Notes. Pursuant to
                              the Registration Rights Agreement, the Company
                              agreed to use its best efforts to file an
                              Exchange Offer Registration Statement (as
                              defined). The Registration Statement of which
                              this Prospectus is a part constitutes the
                              Exchange Offer Registration Statement. Under
                              certain circumstances, certain Holders of Notes
                              (including Holders of Notes who may not
                              participate in the Exchange Offer or who may not
                              freely resell New Notes received in the Exchange
                              Offer) may require the Company to file, and cause
                              to become effective, a shelf registration
                              statement under the Securities Act, which would
                              cover resales of Notes by such Holders before
                              making a decision to tender their Old Notes in
                              the Exchange Offer.
 
Use of Proceeds.............  The Company will not receive any proceeds from
                              the Exchange Offer. The Company intends to use
                              the proceeds of the offering of the Old Notes to
                              finance the construction, capital expenditure and
                              working capital requirements (including debt
                              service and repayment obligations) of the Company
                              and, potentially, to refinance existing
                              indebtedness. In addition, a portion of the net
                              proceeds of the offering of the Old Notes may
                              also be used to make acquisitions of businesses
                              or assets related to the Company's business. See
                              "Use of Proceeds."
 
Governing Law and             The Notes and the Indentures will be governed
Judgments...................  exclusively by the laws of the State of New York.
                              Under the Judiciary Law of the State of New York,
                              a judgment or decree in an action based upon an
                              obligation denominated in a currency other than
                              U.S. dollars will be rendered in the foreign
                              currency of the underlying obligation and
                              converted into U.S. dollars at a rate of exchange
                              prevailing on the date of the entry of the
                              judgment or decree.
 
Form of Notes...............  Each of the New Notes will initially be
                              represented by one or more global New Notes in
                              registered form, without coupons attached
                              (collectively, the "Global New Notes"), each of
                              which will be issued in an aggregate denomination
                              equal to the outstanding principal amount at
                              maturity of the New Notes represented thereby.
                              Except as set forth under "Description of the New
                              Notes," owners of beneficial interests in the
                              Global New Notes will not be entitled to receive
                              physical delivery of New Notes in definitive form
                              or to have the New Notes issued and registered in
                              their names and will not be considered the owners
                              or holders thereof under the applicable
                              Indenture. Interests in the Global New Notes will
                              be shown on, and transfers thereof will be
                              effected only through, records maintained in
                              book-entry form by The Depository Trust Company
                              ("DTC") or

                              accounts as Participants.
 
Listing.....................  Application has been made to list the New Notes
                              on the Luxembourg Stock Exchange.
 
                                  RISK FACTORS
 
  Holders of Old Notes should carefully consider the information set forth
under the caption "Risk Factors" and all other information set forth in this
Prospectus before tendering their Old Notes in the Exchange Offer, although the
risk factors (other than "--Consequences of Failure to Exchange Old Notes" and
"--Requirements for Transfer of New Notes") are generally applicable to the Old
Notes as well as the New Notes.
 
                                       17

                                 RISK FACTORS
 
  Holders of Old Notes should consider carefully all of the information set
forth in this Prospectus and incorporated by reference in this Prospectus. See
"Available Information" and "Incorporation of Documents By Reference." Holders
should particularly evaluate the following risks before tendering their Old
Notes in the Exchange Offer, although the risk factors set forth below (other
than the first two risk factors) are generally applicable to the New Notes as
well as the Old Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Issuance of the New Notes in exchange for the Old Notes pursuant to the
Exchange Offer will be made following the prior satisfaction, or waiver, of
the conditions set forth in "The Exchange Offer--Certain Conditions to the
Exchange Offer" and only after a timely receipt by the Exchange Agent of such
Old Notes, a properly completed and duly executed Letter of Transmittal in
respect of such Old Notes and all other required documents. Therefore, holders
of Old Notes desiring to tender such Old Notes in exchange for New Notes
should allow sufficient time to ensure timely delivery. Neither the Exchange
Agent nor the Company is under any duty to give notification of defects or
irregularities with respect to the tenders of Old Notes for exchange. Old
Notes that are not tendered or are tendered but not accepted will, following
the consummation of the Exchange Offer, continue to be subject to the
provisions of the applicable Indenture regarding transfer and exchange of the
Old Notes, the existing restrictions upon transfer thereof set forth in the
legend on the Old Notes and in the Offering Memorandum dated March 6, 1998
relating to the Old Notes (the "Offering Memorandum"). Except in certain
limited circumstances with respect to certain types of holders of Old Notes
(see "Registration Rights"), the Company will have no further obligation to
provide for the registration under the Securities Act of such Old Notes. 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. The
Company does not currently anticipate that it will take any action to register
the Old Notes under the Securities Act or blue sky laws.
 
REQUIREMENTS FOR TRANSFER OF NEW SECURITIES
 
  Based on interpretations by the staff of the Commission, as set forth in no
action letters issued to third parties, the Company believes that the New
Notes issued in exchange for the Old Notes, pursuant to the Exchange Offer may
be offered for resale, resold or otherwise transferred by Holders thereof
(other than any such Holder which is an "affiliate" of the Issuer within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such New Notes are acquired in the ordinary course of such
Holders' business and such Holders have no arrangement with any person to
participate in the distribution (within the meaning of the Securities Act) of
such New Notes. Each Holder, other than a broker-dealer, must acknowledge that
it is not engaged in, and does not intend to engage in, and has no arrangement
or understanding with any person to participate in, a distribution of New
Notes. If any Holder is an affiliate of the Company, is engaged in or intends
to engage in or has any arrangement or understanding with respect to the
distribution of the New Notes to be acquired pursuant to the Exchange Offer,
such Holder (i) could not rely on the applicable interpretations of the staff
of the Commission and (ii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transactions. Each broker-dealer who holds Old Notes acquired for its own
account as a result of market-making activities or other trading activities,
and who receives New Notes in exchange for such Old Notes pursuant to the
Exchange Offer, may be an "underwriter" within the meaning of the Securities
Act and must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging 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. 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 by such broker-dealer as a result
of market-making activities or other trading
 
                                      18

activities. The Company has agreed that starting on the Expiration Date and
ending on the close of business of the 180th day following the Expiration
Date, it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution." However, to
comply with the securities laws of certain jurisdictions, if applicable, the
New Notes may not be offered or sold unless they have been registered or
qualified for sale in such jurisdictions or an exemption from registration nor
qualification is available and is complied with. The Company has agreed,
pursuant to the Registration Right Agreements and subject to certain specified
limitations therein, to register or qualify the New Notes for offer or sale
under the securities or blue sky laws of such jurisdiction as any holder of
the Notes reasonably request in writing. Unless the Company is so requested,
the Company does not intend to take any action to register or qualify the sale
of the New Notes in any such jurisdictions. See "The Exchange Offer--
Consequences of Exchanging Old Notes."
 
POTENTIAL ADVERSE CONSEQUENCES OF LEVERAGE
 
  The Company is and, following the consummation of the Exchange Offer will
continue to be, highly leveraged. At March 31, 1998, the accrued value of the
Company's total long-term indebtedness (including the Redeemable Preferred
Stock (as defined)) was approximately $3.5 billion, representing approximately
104% of total capitalization. Chase has agreed under the New Credit Facility
to fully underwrite a (Pounds)555 million term loan facility. By April 14,
1999, Chase's commitment will be reduced to no less than (Pounds)480 million
or such greater amount as is necessary to ensure that the Company's UK
operations remain fully funded by reference to an agreed business plan. As the
Company's subsidiaries draw down amounts available under the New Credit
Facility, the amount of debt outstanding will increase further. The indentures
governing the Existing Notes and the Convertible Notes permit the Company and
its subsidiaries to incur substantial additional indebtedness. The ability of
the Company and its subsidiaries to make scheduled payments under present and
future indebtedness (including the Notes) will depend on, among other things,
the Company's and its subsidiaries' ability to complete the build out of the
franchises on a timely and cost effective basis, the Company's ability to
access the earnings of its subsidiaries (which may be subject to significant
contractual and legal limitations), the future operating performance of the
Company and its subsidiaries and the Company's ability to refinance its
indebtedness when necessary. Each of these factors is to a large extent
subject to economic, financial, competitive, regulatory and other factors that
are beyond the Company's and its subsidiaries' control. See "--Uncertainty of
Construction Progress and Costs," "--Need for Additional Financing" and "--
Holding Company Structure; Dependence Upon Cash Flow from Subsidiaries."
 
  The New Credit Facility contains, and future agreements and debt instruments
may contain, various covenants which, among other things, require the Company
to maintain certain financial ratios, restrict or prohibit the payment of
dividends and other distributions to the Company by its subsidiaries, restrict
asset sales and dictate the use of proceeds from the sale of assets. Although
the Company believes that it and its subsidiaries are in compliance with their
respective covenants and restrictions, continued compliance with these
restrictions, in combination with the leveraged nature of the Company, could
limit the ability of the Company to respond to market conditions or meet
extraordinary capital needs or otherwise could restrict corporate activities
and the ability of certain subsidiaries of the Company to make payments to the
Company which might otherwise fund payments due on the Notes and the Company's
other obligations as they fall due. See "--Holding Company Structure;
Dependence Upon Cash Flow from Subsidiaries." There can be no assurance that
such restrictions will not adversely affect the Company's ability to finance
its future operations or capital needs, to service and repay indebtedness
(including, without limitation, the Notes) or to engage in other business
activities, such as acquisitions, which may be in the interest of the Company.
 
  The degree to which the Company is leveraged could have important
consequences to holders of the Notes including the following: (i) increasing
the Company's vulnerability to adverse changes in general economic conditions
or increases in prevailing interest rates; (ii) limiting the Company's 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 the Company's
business; (iii) requiring a substantial portion of the Company's and its
subsidiaries' cash flow from operations to be
 
                                      19
<PAGE>
 
dedicated to debt service requirements, thereby reducing the funds available
for dividends, operations and future business opportunities; and (iv)
increasing the Company's and its subsidiaries' exposure to increases in
interest rates given that certain of the Company's and its subsidiaries'
borrowings may be at variable rates of interest.
 
  In addition, the Company may under certain circumstances be obligated to
offer to repurchase certain outstanding securities prior to maturity and there
can be no assurance that the Company will have the financial resources
necessary or otherwise be able to repurchase those securities in such
circumstances (including, without limitation, on the occurrence of a Change in
Control Triggering Event).
 
NEED FOR ADDITIONAL FINANCING
 
  The Company will continue to require significant amounts of capital to
finance construction of its local and national networks, for connection of
telephone, telecommunications and CATV customers to the networks, for other
capital expenditures, as well as for cash interest payments. Based on the
information currently available, the Company estimates that, from April 1,
1998 through March 31, 1999, these requirements will aggregate (Pounds)354
million (approximately $580 million). The Company intends to fund its
requirements from cash, cash equivalents and marketable securities on hand of
$1.2 billion as of March 31, 1998. The Company has significant capital
requirements for the completion of its telephone, telecommunications and CATV
network passed the total of 2,090,000 homes required by its regulatory build
schedules, for its LDL payments and for scheduled cash interest and principal
payments beyond March 31, 1999. In addition, the Company will require
significant amounts of capital to finance the other capital expenditures and
the cost of operations of the Company, its subsidiaries and joint ventures and
meet all their other obligations as they fall due. The Company intends to fund
the requirements referred to in this paragraph from cash, cash equivalents and
marketable securities on hand, amounts available under the New Credit Facility
and funds internally generated by the operations of the Company's
subsidiaries, but there can be no assurance that such resources will be
available or adequate to meet expected requirements. See "Description of
Certain Indebtedness--The New Credit Facility."
 
  In addition, all or a substantial portion of the indebtedness of the Company
(other than the Notes) matures prior to the maturity of the Notes. The
Company's ability to make cash payments pursuant to the terms of the Notes may
be dependent, in part, on the Company's ability to refinance that indebtedness
which will depend, in part, on factors beyond the control of the Company. The
Redeemable Preferred Stock is mandatorily redeemable on February 15, 2009 and
such mandatory redemption provisions may have a material adverse effect on the
Company's ability to obtain additional financing or refinancing.
 
  Management does not anticipate that the Company and its subsidiaries will
generate sufficient cash flow from operations to repay at maturity the entire
principal amount of the Existing Notes, the Convertible Notes and other
outstanding indebtedness of the Company and its subsidiaries. In addition, it
may be necessary for the Company to refinance the Notes at maturity.
Accordingly, the Company will be required to consider a number of measures,
including: (i) refinancing all or a portion of such indebtedness, (ii) seeking
modifications of the terms of such indebtedness, (iii) seeking additional debt
financing, which would be subject to obtaining necessary lender consents, (iv)
seeking additional equity financing, or (v) a combination of the foregoing.
The particular measures the Company may undertake and the ability of the
Company to accomplish those measures will depend on the financial condition of
the Company and its subsidiaries at the time, as well as a number of factors
beyond the control of the Company and its subsidiaries, including prevailing
economic and market conditions and financial, business and other factors. No
assurance can be given that any of the foregoing measures can be accomplished,
or can be accomplished in sufficient time to make timely payments with respect
to the Company's indebtedness. In addition, there can be no assurance that any
such measures can be accomplished on terms which are favorable to the Company
and its subsidiaries.
 
  The Company will continue to consider strategic acquisitions and
combinations involving businesses operating, or owning licenses to operate,
cable, telephone, television or telecommunications systems or services and
related businesses principally in the United Kingdom, as attractive
opportunities arise. The Company is currently involved in various stages of
exploration, development and negotiation of certain transactions, some of
 
                                      20
<PAGE>
 
which, if completed, would be significant and may involve the incurrence of
substantial indebtedness or the raising of additional equity by the Company
and its subsidiaries to finance such transactions. There can be no assurances
that such transactions will occur. The indentures governing the Notes and the
Existing Notes permit indebtedness to be incurred to finance acquisitions only
if such acquisitions are acquisitions of either tangible or intangible assets,
licenses and computer software used in connection with a Cable Business (as
defined in such indentures) or certain entities, directly or indirectly
engaged in a Cable Business if such entities meet certain qualifying criteria
specified in such indentures.
 
HOLDING COMPANY STRUCTURE; DEPENDENCE UPON CASH FLOW FROM SUBSIDIARIES
 
  The Company is a holding company that conducts its operations through its
direct and indirect wholly-owned subsidiaries and affiliated joint ventures.
As a holding company, the Company holds no significant assets other than its
investments in and advances to its subsidiaries and affiliated joint ventures.
The Company is, therefore, dependent upon its receipt of sufficient funds from
its subsidiaries and affiliated joint ventures to meet its own obligations.
The ability of the Company and, therefore, the holders of the Notes, to
benefit in the distribution of any assets of any of the Company's subsidiaries
and affiliated joint ventures upon any liquidation of any such subsidiary or
joint venture will be subject to the prior claims of the subsidiary's or joint
venture's creditors, including trade creditors and, to the extent that such
subsidiary or joint venture is not directly owned by the Company, to the prior
claims of the creditors of any other persons directly or indirectly owning
such subsidiary or joint venture.
 
  Each of the Company's subsidiaries that is a Delaware corporation may pay
dividends, under the Delaware General Corporation Law (the "DGCL"), only out
of its surplus, or, in the event that it has no surplus, out of its net
profits for the fiscal year in which the dividend is declared or for the
immediately preceding fiscal year. Each of the Company's subsidiaries that is
a United Kingdom company is, under applicable United Kingdom law, prohibited
from paying dividends unless such payments are made out of profits available
for distribution (which consist of accumulated, realized profits, so far as
not previously utilized by distribution or capitalization, less accumulated,
realized losses, so far as not previously written off in a reduction or
reorganization of capital duly made). Other statutory and general English law
obligations also affect the ability of directors of the Company's subsidiaries
to declare dividends and the ability of the Company's subsidiaries to make
payments to the Company on account of intercompany loans. In addition, the
United Kingdom may impose a withholding tax on payments of interest and
advance corporation tax on distributions (of interest, dividends or otherwise)
by United Kingdom subsidiaries of the Company.
 
  In addition, the terms of the New Credit Facility limit, and the terms of
existing and future indebtedness of the Company's subsidiaries may limit, the
payment of dividends, loans or other distributions to the Company. In the
absence of a default, the New Credit Facility generally permits payments to
the Company to pay the interest and principal of existing indebtedness of the
Company. See "Description of Certain Indebtedness--The New Credit Facility."
 
  The Old Notes are, and the New Notes will be, effectively subordinated to
all existing and future indebtedness and other liabilities and commitments of
the Company's subsidiaries, including borrowings under
the New Credit Facility. As of March 31, 1998, the total liabilities of the
Company's subsidiaries were approximately $342 million ((Pounds)205 million).
In addition, the Indentures permit subsidiaries of the Company to incur
additional Indebtedness (as defined in the Indentures) to finance the
construction, capital expenditure and working capital needs of a Cable
Business and the acquisition of Cable Assets (as defined in the Indentures) or
the acquisitions of certain entities, directly or indirectly, engaged in a
Cable Business, if such entities meet certain qualifying criteria specified in
the Indentures. In light of the Company's strategy of continued growth, in
part through acquisitions, the Company and its subsidiaries may incur
substantial indebtedness in the future. See "Description of New Notes."
Borrowings under the New Credit Facility are, and a substantial portion of the
Company's and its subsidiaries' future indebtedness is expected to be, secured
by liens and other security interests over the assets of the Company's
subsidiaries and the Company's equity interests in the Company's subsidiaries.
In addition, the ability of the Company and, therefore, the holders of the
Notes to benefit from
 
                                      21
<PAGE>
 
distributions of assets of the Company's subsidiaries may be limited to the
extent that the outstanding shares of any of its subsidiaries and such
subsidiary's assets are pledged to secure other debt of the Company or its
subsidiaries. Any right of the Company to receive assets of any subsidiary
upon such subsidiary's liquidation or reorganization will be structurally
subordinated to the claims of that subsidiary's creditors, except to the
extent that the Company is itself recognized as an unsubordinated creditor of
such subsidiary. However, to the extent that the Company is so recognized, the
claims of the Company would still be subject to any security interests in the
assets of such subsidiary and any liabilities of such subsidiary senior to
those held by the Company and may otherwise be challenged by third parties in
a liquidation or reorganization proceeding. In addition, the New Credit
Facility requires the Company to subordinate its right to repayment of
indebtedness outstanding between it and the borrower under such agreement or
any other subsidiary of the Company to the rights of the lenders under the
agreement. In particular the rights of the Company and other subsidiaries to
repayment of principal and interest lent by them to the borrower or other
subsidiaries under the New Credit Facility have been and will be subordinated
to the rights of the lenders under the New Credit Facility pursuant to
subordination agreements with such lenders.
 
  The principal fixed assets of the Company's subsidiaries are cable headends,
cable television and telecommunications distribution equipment,
telecommunications switches and customer equipment, transmission towers, masts
and antennas and the sites on which they are located. The value of a
substantial portion of these fixed assets is derived from their employment in
the Company's and its subsidiaries' businesses. These assets are highly
specialized and, taken individually, can be expected to have limited
marketability. Consequently, in the event that secured creditors seek to
realize on the collateral securing debt of the Company's subsidiaries, these
creditors would be likely to seek to sell the business as a going concern
(possibly through a sale of pledged shares of subsidiaries), either in its
entirety, or by franchise or other business unit, in order to maximize the
proceeds realized.
 
THE PROPOSED PARTNERS ACQUISITION
 
  The Company has entered into the Amalgamation Agreement to acquire Partners.
See "Prospectus Summary--Recent Development". Any benefits from the
Amalgamation could be less than anticipated. Other potential risks include the
risk that integration of Partners with the Company and with the Company's
national transmission network may be more difficult than expected, the
presence of unknown liabilities and the lack of majority control of certain
assets (the Cable London Equity Interest and the Birmingham Cable Equity
Interest), and the possible loss of those assets upon exercise of the Purchase
Rights. While there have been various oral communications and written
correspondence between NTL and Partners, on the one hand, and TeleWest, on the
other hand, with respect to matters related to the Purchase Rights, the
parties have no agreement, arrangement or understanding with respect to the
Purchase Rights and there can be no assurances that the parties will reach any
such agreement, arrangement or understanding prior to the consummation of the
Amalgamation. On April 16, 1998, TeleWest announced that, subject to the
valuation and the availability of financing, it proposed to exercise the
Purchase Rights. There can be no assurances that TeleWest will exercise either
or both of the Purchase Rights. While the Company believes that the
acquisition of Partners will be beneficial to the Company and its
shareholders, there can be no assurance that (i) if completed, the expected
benefits will be realized, (ii) the potential risks will not be realized, or
(iii) such risks can be managed without adversely affecting the Company.
 
  The Company has not yet determined whether the Amalgamated Company will be
treated as a Restricted Subsidiary or a Non-Restricted Subsidiary under the
Indentures, although designation as a Non-Restricted Subsidiary would require
consent of a majority of the holders under each of the Indentures governing
the Existing Notes. If the Amalgamated Company is designated as a Non-
Restricted Subsidiary, it will not be subject to the covenants of the
Indentures. Even if the Amalgamated Company is designated as a Restricted
Subsidiary, it may continue to be subject to the restrictions on payment of
dividends to the Company and other restrictive covenants
 
                                      22
<PAGE>
 
contained in Partners' existing debt instruments. As a result of such
restrictions, there can be no assurance that the Company will be able to gain
access to the cash flow of Partners as a source of payment for the Notes or
for the Company's other indebtedness. There can also be no assurance that the
Amalgamation will be completed, or of the timing of any such completion.
 
OPERATING LOSSES
 
  The Company had net losses for the three months ended March 31, 1998 and
1997 and for the years ended December 31, 1997, 1996, 1995, 1994 and 1993 of
$(93.7 million), $(85.8 million), $(333.1 million), $(254.5 million), $(90.8
million), $(29.6 million) and $(11.1 million), respectively. As of March 31,
1998, the Company's accumulated deficit was $810.7 million. The development of
the Company's business to date has resulted in significant expenditures and
the continued construction and expansion of its network will require
considerable additional expenditures. Construction and operating expenditures
have resulted in negative cash flow, which is expected to continue at least
until an adequate customer base is established. The Company also expects to
incur substantial additional operating losses, and there can be no assurance
that the Company will achieve or sustain profitability in the future. Failure
to become profitable could adversely affect the Company's ability to sustain
operations and obtain additional required funds. See "--Need for Additional
Financing." Moreover, such a failure would adversely affect the Company's
ability to pay the required payments on the Notes, the Company's other
indebtedness and the Redeemable Preferred Stock. See "--Potential Adverse
Consequences of Leverage," "--Need for Additional Financing" and "--Holding
Company Structure; Dependence Upon Cash Flow from Subsidiaries."
 
DEFICIENCY OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES
AND PREFERRED STOCK DIVIDENDS
 
  For the three months ended March 31, 1998 and the years ended December 31,
1997, 1996, 1995, 1994 and 1993, the Company's earnings were insufficient to
cover fixed charges by approximately $94.6 million, $355.4 million, $257.1
million, $105.4 million, $31.8 million and $10.4 million, respectively. The
Company's earnings for the three months ended March 31, 1998 and the year
ended December 31, 1997 were insufficient to cover combined fixed charges and
preferred stock dividends by $98.2 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. The issuance of the Old Notes had the effect of increasing the total
amount of the Company's indebtedness and increasing its interest expense in
subsequent periods.
 
REQUIREMENT TO MEET BUILD MILESTONES
 
  The telecommunications license for each franchise contains specific
construction milestones. Under the terms of its current telecommunications
licenses, by the end of 2005 the Company is required to construct cable
television systems passing an aggregate of approximately 2,090,000 premises
(residential and business). The Office of Telecommunications ("OFTEL") and the
Department of Trade and Industry ("DTI") are the only bodies with the
authority to modify the construction milestones in the licenses other than the
Northern Ireland and Gwent and Glamorgan local delivery operator licenses
("LDLs") (in respect of which the Independent Television Commission (the
"ITC") is the relevant authority for modifying construction milestones). Based
on current network construction, the Company believes it will be able to
satisfy the Company's milestones in the future, but there can be no assurance
that such milestones will be met. See "--Need for Additional Financing" and
"-- Uncertainty of Construction Progress and Costs." If the Company is unable
to meet the construction milestones required by any of its licenses and is
unable to obtain modifications to the milestones, the relevant license or
licenses could be revoked, which would have a material adverse effect on the
Company.
 
UNCERTAINTY OF CONSTRUCTION PROGRESS AND COSTS
 
  At March 31, 1998, construction of the Company's network had passed in
excess of 51% of its final regulatory milestone requirements for all its
franchises. Successful construction and development of the Company's network
will depend on, among other things, the Company's ability to continue to
design network
 
                                      23
<PAGE>
 
routes, install facilities, obtain and maintain any required government
licenses or approvals and finance construction and development, all in a
timely manner, at reasonable costs and on satisfactory terms and conditions.
The exact amounts and timing of all of these expenditures are subject to a
variety of factors which may vary greatly by market and be beyond the control
of the Company. Accordingly, there can be no assurance that the actual costs
of network construction will not exceed the aggregate cost of network
construction estimated under "--Need for Additional Financing" above or that
additional funding substantially in excess of that amount will not be
required.
 
  In building its network, the Company is generally required by its licenses
to use underground construction, which is more expensive and time consuming
than aerial construction. Mechanized construction methods often cannot be used
to install network infrastructure in the Company's franchise areas due to
existing underground utility infrastructure. In addition, the Company is
responsible for restoring the surface area after its underground construction
is completed. Although the Company has recently been able to negotiate
construction contracts at rates which it believes are competitive relative to
the cable industry as a whole, construction costs could increase significantly
over the next few years as existing contracts expire and as demand for cable
construction services grows due to anticipated increases in the cable
industry's overall construction activity. Accordingly, there can be no
assurance that the Company will be able to construct its network in a timely
manner or at a reasonable cost.
 
POSSIBILITY OF INCREASED CUSTOMER CHURN
 
  Although historically the Company has experienced lower rates of churn than
other operators offering similar services, there can be no assurance as to the
Company's future churn rates. Higher levels of churn could have a material
adverse effect on the Company.
 
SIGNIFICANT COMPETITION
 
  The Company faces significant competition from established and new
competitors in the areas of residential telephony, business telecoms services
and cable television. The Company believes that competition will intensify in
each of these business areas, particularly business telecommunications.
 
  Residential Telephony. The Company competes primarily with BT in providing
telephone services to residential customers. BT, formerly the only major
national PTO in the United Kingdom, has an established market presence, fully
built networks and resources substantially greater than those of the Company.
According to OFTEL, at March 31, 1997, nearly 90% of United Kingdom
residential telephone exchange line customers are customers of BT. The
Company's growth in telecommunications services, therefore, depends upon its
ability to convince BT's customers to switch to the Company's
telecommunications services. The Company believes that value for money is
currently one of the most important factors influencing the decision of United
Kingdom customers to switch from BT to a cable telecommunications service. BT
has, however, introduced price reductions in certain categories of calls and,
due to regulatory price controls, BT will be making further reductions in its
telecommunications prices. Accordingly, although the Company intends to remain
competitive, in the future it may be unable to offer residential telephone
services at rates lower than those offered by BT. In such case, the Company
may experience a decline in its average per line residential
telecommunications revenues, may not achieve desired penetration rates and may
experience a decline in total revenues. There can be no assurance that any
such decline in revenues or penetration rates will not adversely affect the of
the Company. In addition to BT, other telecommunications competitors which may
have substantially greater resources than those of the Company could prevent
the Company from increasing its share of the residential telecommunications
market.
 
  On February 8, 1996, the DTI announced the award of two licenses to operate
radio fixed access services in the 2 GHz band. These new licenses enable the
two licensees, BT and RadioTEL Systems, to provide telecommunications services
to customers living in defined remote rural areas mainly in Scotland, Wales
and Northern Ireland and create potential additional competition for the
Company's residential telephony services in
 
                                      24
<PAGE>
 
certain remote rural areas of the Company's Northern Ireland franchise. The
Company also competes with mobile networks. This technology could grow to
become a competitive threat to the Company's networks, particularly if call
charges are reduced further on the mobile networks. The Company's Radio
Communications group may enable the Company to benefit from the growth in this
technology. There can be no assurance, however, that the Company will be able
to compete successfully with BT or such other telecommunications operators.
 
  The Company believes that it has a competitive advantage in the residential
market because of its ability to offer integrated telephone, CATV,
telecommunications services (including interactive and on-line services) and
dual product packages designed to encourage customers to subscribe to both
services. However, there can be no assurance that this competitive advantage
will continue. Indeed, BT, C&WC and other national PTOs will be entitled to
convey CATV services from 2001 and, subject to a review by the Director
General (which is already underway), possibly from as early as 1998.
 
  BSkyB is currently marketing telecommunications services both independently
and on behalf of BT. BSkyB's joint marketing efforts with BT enable BSkyB's
customers to earn additional discounts on BT's residential telecommunications
volume discount plans. In addition, it has been reported from time to time
that BT and BSkyB are discussing the formation of cooperative arrangements.
Given the respective market positions of BT and BSkyB, the Company believes
that, if the two companies successfully combine their respective marketing
strengths, the resulting combination would provide significant competition to
cable operators including the Company.
 
  Business Telecommunications. BT is also the Company's principal competitor
in providing business telecommunications services. In addition, the Company
competes with C&WC, Energis, Scottish Telecom in Scotland and with other
companies that have recently been granted telecommunications licenses such as
WorldCom and Colt. In the future, the Company may compete with additional
entrants to the business telecommunications market, such as AT&T U.K.
Competition is based on price range and quality of services, and the Company
expects price competition to intensify if C&WC, Energis and other new market
entrants compete aggressively. Most of these competitors have substantial
resources and there can be no assurance that these or other competitors will
not expand their businesses in the Company's existing markets or that the
Company will be able to continue to compete successfully with such competitors
in the business telecommunications market.
 
  CATV. The Company's CATV systems compete with direct reception over-the-air
broadcast television, direct-to-home ("DTH") satellite services and satellite
master antenna systems. In addition, pay television and pay-per-view services
offered by the Company compete to varying degrees with other communications
and entertainment media, including home video, cinema exhibition of feature
films, live theater and newly emerging multimedia services. The Company
expects that, in the future, it may face competition from programming provided
by video-on-demand services, including those that may be provided by public
telephone operators ("PTOs") with national licenses (i.e., national PTOs).
Certain companies associated with BT and Mercury (which recently merged with
three cable operators that hold such licenses--NYNEX CableComms, Bell
Cablemedia plc and Videotron Holdings plc--to form a new company known as
Cable & Wireless Communications ("C&WC")) hold licenses to provide cable
telephone/television systems that cannot, under current ITC policy, be built
in any of the Company's franchises. This ITC policy position may change. Any
such change in policy could have a material adverse effect on the Company.
 
  On September 29, 1993, the ITC issued a statement pursuant to which it took
the position (shared by OFTEL and DTI) that BT and the other national PTOs may
provide "video-on-demand" services under their existing licenses. No assurance
can be given that video-on-demand will not provide substantial competition to
the Company within its markets in the future.
 
  The Broadcasting Act 1996 provides for the regulation of digital terrestrial
television ("DTT") that will initially provide an additional 18 or more new
terrestrial channels serving between 60% and 90% of the United Kingdom's
population. Some of the channels are reserved for digital simultaneous
broadcasting by the existing
 
                                      25
<PAGE>
 
terrestrial broadcasters. The introduction of DTT, as well as digital
satellite television will provide both additional programming sources as well
as increased competition for the Company and its subsidiaries. There can be no
assurance that satisfactory (or any) terms of carriage will be obtained by the
Company for digital satellite programs or channels.
 
  The full extent to which existing or future competitors using existing or
developing media will compete with cable television systems may not be known
for several years. There can be no assurance, however, that existing, proposed
or as yet undeveloped technologies will not become dominant in the future and
render cable television systems less profitable or even obsolete.
 
  Broadcast Services. In February 1997, the United Kingdom Government sold the
BBC's Home Service and World Service transmission businesses to a consortium
led by Castle Tower Corporation. There can be no assurance that the Company
will not encounter significant competition from Castle Transmission for its
transmission business from expiration of the Company's current contracts with
the ITV contractors and Channel 4/S4C. See "--Dependence Upon ITV and Other
Contracts." See "--Dependence Upon Site Sharing Arrangement."
 
LIMITED ACCESS TO PROGRAMMING
 
  The Company's ability to make a competitive offering of cable television
services is dependent on the Company's ability to obtain access to programming
at a reasonable cost. While various sources of programming are available to
cable system operators in the United Kingdom, BSkyB is currently the most
important supplier of cable programming and the exclusive supplier of certain
programming. BSkyB provides the industry with a range of programming,
including the most popular mainstream premium movie channels available in the
United Kingdom and, currently, exclusive English premier league soccer games.
BSkyB also competes with the Company by operating a DTH satellite service that
provides programming, including programming that is also offered by the
Company, to approximately 4 million subscribers in the United Kingdom. BSkyB's
programming is important in attracting and retaining cable television
subscribers and, in the absence of more alternative programming sources, BSkyB
may be able to set and raise prices for its programming without significant
competitive pricing pressure.
 
  The Company, like many other cable operators, obtains most of its
programming through arrangements with BSkyB and other programming suppliers
which are not reflected in signed written agreements. To date, the Company has
not had a formal contract with BSkyB, although it has been in discussions with
BSkyB for some time. There can be no assurance that the Company will be able
to enter into a definitive agreement with BSkyB, that the terms of such
definitive agreement will not be less favorable to the Company than the
current arrangement, or that BSkyB will continue to supply programming to the
Company on reasonable commercial terms or at all. Moreover, the Company has
not, to date, entered into written contracts with many of its other program
suppliers. The loss of BSkyB or other programming, a deterioration in the
perceived quality of BSkyB or other programming, or a material increase in the
price that the Company is required to pay for BSkyB or other programming could
have a material adverse effect on the Company.
 
  Because of the factors described in the preceding paragraphs, there can be
no assurance that its current programming will continue to be available to the
Company on acceptable commercial terms, or at all.
 
POSSIBLE CHANGES IN GOVERNMENT REGULATION
 
  The principal business activities of the Company in the United Kingdom are
regulated and supervised by various governmental bodies, the ITC, the
Department of Culture, Media and Sport, the Radio Communications
Agency and OFTEL under the directions of the Director General and the DTI 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 the Company's activities and those of its competitors,
such as licensing requirements,
 
                                      26
<PAGE>
 
changes in price regulation, deregulation of interconnection arrangements,
acceleration of the date (which is scheduled for 2001 but is subject to review
in 1998) from which BT, C&WC and other national PTOs can convey broadcast
entertainment services over their existing national networks or a change in
policy allowing more than one cable licensee in the franchise area could have
a material adverse effect on the Company. The Labour Party, which forms the
current United Kingdom Government, signalled in opposition that it was
inclined to allow the progressive entry of BT into conveyance of national
broadcast entertainment services from 1998 onwards, rather than wait until
2001, or reviewing the matter in 1998. On taking power, the new Government did
not immediately implement this policy, and British newspapers in January 1998
quoted Government sources as suggesting that it would shortly announce a
revised policy of letting BT enter the market in 2000, one year ahead of the
original timescale.
 
  A substantial portion of the Company's business is also subject to
regulation. In particular, the prices that the Company may charge the ITV
companies, Channel 4 and S4C for television transmissions services are subject
to price controls imposed by OFTEL. On December 24, 1996, the Director General
of OFTEL issued the formal modification to the Company's Telecommunications
Act License to deal with the new price control for the television transmission
services provided by the Company to the ITV companies, Channel 4 and S4C.
Under the new arrangements, the total revenues receivable by the Company for
such services (excluding certain insignificant items) could not exceed
(Pounds)53.15 million in 1997 and, thereafter through 2002, will be adjusted
annually by the Retail Prices Index ("RPI") minus 4%. There is no assurance
that these price controls will not be reviewed again by OFTEL prior to 2002 or
that price controls for the years following December 31, 2002 will not have a
material adverse effect on the revenues receivable from the ITV companies,
Channel 4 and S4C.
 
  As the United Kingdom is a member of the European Union ("EU"), the Company
may be subject to regulatory initiatives of the European Commission ("EC").
Changes promulgated in EU Directives, particularly to the extent that they
require an EU television "production" and "programming" quota, may reduce the
range of programs which can be offered and increase the costs of purchasing
television programming. In addition, EU Directives may introduce provisions
requiring the Company and its subsidiaries to provide access to its cable
network infrastructure to other service providers, which could have a material
adverse effect on the Company.
 
DEPENDENCE UPON SITE SHARING ARRANGEMENT
 
  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, Castle Transmission (as successor to the British
Broadcasting Corporation (the "BBC")) and the Company have made arrangements
to share a large number of sites. Under the present arrangements, one of the
parties (the "Station Owner") is the owner, lessee or licensee of each site
and the other party (the "Sharer") is entitled to request a license to use
certain 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) and provides that, if requested by the Sharer, it will be extended
for further periods. The site sharing agreement and each site license provide
for the Station Owner to be paid a commercial license fee and for the Sharer
to be responsible, in normal circumstances, for the costs of accommodation and
equipment used exclusively by it. 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. Although the Company does not anticipate that the site sharing agreement
or the site licenses will be terminated, there can be no assurance that such a
termination will not occur. Termination of the site sharing arrangements would
have a material adverse effect on the Company's business.
 
DEPENDENCE UPON ITV AND OTHER CONTRACTS
 
  The Company's broadcast services business is substantially dependent upon
contracts with the ITV contractors, Channel 4/S4C and Vodafone for the
provision of transmission services. The prices that the
Company may charge these companies for television transmission services are
subject to regulation by OFTEL. See "--Possible Changes in Government
Regulation." The contracts with the ITV contractors and Channel
 
                                      27
<PAGE>
 
4/S4C terminate on December 31, 2002. Although, historically, the ITV
contractors and Channel 4/S4C have renewed their contracts with the Company,
there can be no assurance that they will do so upon expiration of the current
contracts, that they will not negotiate terms for the Company's provision of
transmission services on a basis less favorable to the Company or that they
would not seek to obtain from third parties a portion of the transmission
services currently provided by the Company. The loss of any one of these
contracts could have a material adverse effect on the Company.
 
MANAGEMENT OF GROWTH AND EXPANSION
 
  The Company has experienced rapid growth and development in a relatively
short period of time and plans to continue to do so to meet its strategic
objectives and regulatory milestones. The management of such growth will
require, among other things, stringent control of construction and other
costs, continued development of the Company's financial and management
controls, increased marketing activities and the training of new personnel.
Failure to manage its rapid growth and development successfully could have a
material adverse effect on the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's businesses are managed by a small number of key executive
officers, the loss of one or more of whom could have a material adverse effect
on the Company. The Company believes that its future success will depend in
large part on its continued ability to attract and retain highly skilled and
qualified personnel. The Company has not entered into written employment
contracts or non-compete agreements with, nor has it obtained life insurance
policies covering, such key executive officers. Certain senior managers of the
Company also serve as members of senior management of other companies in the
telecommunications business.
 
RAPID TECHNOLOGICAL CHANGES
 
  The telecommunications industry is subject to rapid and significant changes
in technology and the effect of technological changes on the businesses of the
Company cannot be predicted. However, the cost of implementation of emerging
and future technologies could be significant, and the Company's ability to
fund such implementation will depend on its ability to obtain additional
financing. See "--Need for Additional Financing."
 
CURRENCY RISK
 
  To the extent that the Company obtains financing in United States dollars
and incurs construction and operating expenses in British pounds sterling, it
will encounter currency exchange rate risks. In addition, the Company's
revenues are generated primarily in British pounds sterling while its interest
and principal obligations with respect to most of the Company's existing
indebtedness are payable in United States dollars. While the Company may
consider entering into transactions to hedge the risk of exchange rate
fluctuations, there can be no assurance that the Company will engage in such
transactions, or, if the Company decides to engage in such transactions, that
they will be successful and that shifts in the currency exchange rates will
not have a material adverse effect on the Company.
 
SUBSTITUTION OF CURRENCY
 
  Although there can be no assurance that a single European currency will be
adopted or, if adopted, on what time schedule, the Treaty on the European
Economic and Monetary Union provides for the introduction of the Euro in
substitution for the national currencies of the member states which adopt the
Euro. If the United Kingdom adopts the Euro, the regulations of the European
Commission relating to the Euro shall apply to each of the Sterling Senior
Notes, the Sterling Deferred Coupon Notes, the Sterling Senior Notes Indenture
and the Sterling Deferred Coupon Notes Indenture. The circumstances and
consequences described in this paragraph entitle neither the Company nor any
holder of the Sterling Senior Notes or Sterling Deferred Coupon Notes to early
redemption, rescission, notice or repudiation of the terms and conditions of
the Sterling Senior Notes or Sterling Deferred Coupon Notes or the applicable
Indentures or to raise other defenses or to request any compensation claim,
nor will they affect any of the other obligations of the Company under the
Sterling Senior Notes or Sterling Deferred Coupon Notes and the applicable
Indentures.
 
                                      28
<PAGE>
 
INSURANCE COVERAGE
 
  The Company obtains insurance of the type and in the amounts that it
believes are customary in the United Kingdom for similar companies. Consistent
with this practice, the Company does not insure the underground portion of its
cable network. Any catastrophe affecting a significant portion of the
Company's underground cable network could result in substantial uninsured
losses.
 
LACK OF PUBLIC MARKET FOR THE NOTES
 
  The Old Notes were offered to a small number of institutional buyers and are
eligible for trading in the PORTAL Market. The New Notes will be a new issue
of securities in which there is no existing trading market. Although the
Initial Purchasers have informed the Company that they currently intend to
make a market in the New Notes, they are not obligated to do so and any such
market making may be discontinued at any time without notice. The Company does
not intend to apply for listing for the New Notes on any securities exchange
(other than the Luxembourg Stock Exchange) or to seek approval for quotation
through any automated quotation system. Accordingly, there can be no assurance
as to the ongoing development or liquidity of any market for the New Notes. If
an active public market for the New Notes does not develop or is interrupted,
the market price and liquidity of the New Notes may be adversely affected.

                              THE EXCHANGE OFFER
 
TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES
 
  The Old Notes were sold by the Company to the Initial Purchasers on March
13, 1998 pursuant to a Purchase Agreement, dated March 6, 1998. Upon the terms
and subject to the conditions set forth in this Prospectus and in the
accompanying Letter of Transmittal (which together constitute the Exchange
Offer), the Company will accept for exchange Old Notes which are properly
tendered on or prior to the Expiration Date and not withdrawn as permitted
below. As used herein, the term "Expiration Date" means 5:00 p.m., New York
City time, on     1998; provided however, that if the Company, in its sole
discretion, has extended the period of time for which the Exchange Offer is
open, the term "Expiration Date" means the latest time and date to which the
Exchange Offer is extended.
 
  As of the date of this Prospectus, (Pounds)125,000,000 aggregate principal
amount of the Old Sterling Senior Notes, (Pounds)300,000,000 aggregate
principal amount at maturity of the Old Sterling Deferred Coupon Notes and
$1,300,000,000 aggregate principal amount at maturity of the Old USD Deferred
Coupon Notes were outstanding. 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 the Company. The Company's obligation to
accept Old Notes for exchange pursuant to the Exchange Offer is subject to
certain conditions as set forth under "Certain Conditions to the Exchange
Offer" below.
 
  The Company expressly reserves the right, at any time or from time to time,
to extend the period of time during which the Exchange Offer is open, and
thereby delay acceptance for exchange of any Old Notes, by giving oral or
written notice of such extension to the Holders thereof. During any such
extension, all Old Notes previously tendered will remain subject to the
Exchange Offer and may be accepted for exchange by the Company. Any Old Notes
not accepted for exchange for any reason will be returned without expense to
the tendering Holder thereof as promptly as practicable after the expiration
or termination of the Exchange Offer.
 
  Old Notes tendered in the Exchange Offer must be in denominations of
principal amount of $1,000 or (Pounds)1,000, as applicable, and any integral
multiple thereof.
 
  The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted
for exchange, upon the occurrence of any of the conditions of the Exchange
Offer specified below under "Certain Conditions to the Exchange Offer." The
Company will give oral or written notice of any extension, amendment, non-
acceptance or termination to the Holders of the Old Notes as promptly as
practicable, such notice in the case of any extension to 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.
 
PROCEDURES FOR TENDERING OLD NOTES
 
  The tender to the Company of Old Notes by a Holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering Holder and the Company upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal in respect of the applicable Old Notes, as the case may
be. Except as set forth below, a Holder (which term, for purposes of the
Exchange Offer, includes any participant in the Book-Entry Transfer Facility
(as defined) system whose name appears on a security position listing as the
holder of such Old Notes) who wishes to tender Old Notes for exchange pursuant
to the Exchange Offer must transmit the Letter of Transmittal, properly
completed and duly executed, including all other documents required by such
Letter of Transmittal or (in the case of a book-entry transfer) an Agent's
Message in lieu of such Letter of Transmittal to The Chase Manhattan Bank (the
"Exchange Agent") at one of the addresses set forth below under "Exchange
Agent", on or prior to the Expiration Date. In addition, either (i)
certificates for such Old Notes must be received by the Exchange Agent along
with the Letter of Transmittal prior to the Expiration Date, (ii) a timely
confirmation of a book-entry
 
                                      30
<PAGE>
 
transfer (a "Book-Entry Confirmation") of such Old Notes, if such procedure is
available, into the appropriate Exchange Agent's account at DTC (the "Book-
Entry Transfer Facility") pursuant to the procedure for book-entry transfer
described below, must be received by the Exchange Agent prior to the
Expiration Date along with the Letter of Transmittal or an Agent's Message in
lieu of a Letter of Transmittal, or (iii) the Holder must comply with the
guaranteed delivery procedures described below. The term "Agent's Message"
means a message, transmitted by the Book-Entry Transfer Facility to and
received by the appropriate Exchange Agent and forming a part of a Book-Entry
Confirmation, which states that the Book-Entry Transfer Facility has received
an express acknowledgment from the tendering participant, which acknowledgment
states that such participant has received and agrees to be bound by, and make
the representations and warranties contained in, the appropriate Letter of
Transmittal and that the Company may enforce such Letter of Transmittal
against such participant.
 
  THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH
DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED,
WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD NOTES
SHOULD BE SENT TO THE COMPANY.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by a Holder of the Old Notes who has not
completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution (as defined below). In the event that signatures on a
Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantees must be by a firm which is a member
of a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc. or 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 (collectively, "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 the Company in its sole discretion, duly
executed by the registered Holder with the signature thereon 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 the Company in its sole discretion, which determination shall be final and
binding. The Company reserves 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 the judgment of the Company or
its counsel, be unlawful. The Company also reserves 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 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 thereto) by the Company shall be final and binding on all
parties. Unless waived, any defects or irregularities in connection with
tenders of Old Notes for exchange must be cured within such reasonable period
of time as the Company shall determine. Neither the Company, the Exchange
Agent nor any other person shall be under any duty to give notification of any
defect or irregularity with respect to any tender of Old Notes 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, such Old Notes must be endorsed or
accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered Holder or Holders that appear on the
Old Notes.
 
  If a Letter of Transmittal or 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
 
                                      31
<PAGE>
 
representative capacity, such persons should so indicate when signing, and,
unless waived by the Company, proper evidence satisfactory to the Company of
their authority to so act must be submitted with the Letter of Transmittal.
 
  By tendering, each Holder will represent to the Company that, among other
things, the New Notes acquired pursuant to the Exchange Offer are being
obtained in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the Holder, that neither the Holder nor
any such other person has an arrangement or understanding with any person to
participate in the distribution of such New Notes and that neither the Holder
nor any such other person is an "affiliate," as defined under Rule 405 of the
Securities Act, of the Company. If any Holder is an affiliate of the Company,
is engaged in or intends to engage in or has any arrangement with any person
to participate in the distribution of the New Notes to be acquired pursuant to
the Exchange Offer, such Holders (i) could not rely on the applicable
interpretations of the staff of the Commission and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer who holds Old Notes
acquired for its own account as a result of market-making activities or other
trading activities, and who receives New Notes in exchange for such Old Notes
pursuant to the Exchange Offer, may be an "underwriter" within the meaning of
the Securities Act and must acknowledge that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale
of such New Notes. The Letter of Transmittal states that by so acknowledging
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.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
  Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company 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. See "Certain
Conditions to the Exchange Offer" below. For purposes of the Exchange Offer,
the Company shall be deemed to have accepted properly tendered Old Notes for
exchange when, as and if the Company has given oral (promptly confirmed in
writing) or written notice thereof 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. If the Exchange Offer is not
consummated by January 17, 1999, special interest will accrue (in addition, in
the case of the Old Sterling Senior Notes, to the stated interest on the Old
Sterling Senior Notes and, in the case of the Old Sterling Deferred Coupon
Notes and the Old USD Deferred Coupon Notes, in addition to the amortization
of original issue discount and stated interest) from and including January 18,
1999. Special interest, if any, will be payable in cash semiannually in
arrears each April 1 and October 1, respectively, to holders of record of the
Old Notes on the immediately preceding March 15 and September 15,
respectively, at a rate per annum equal to 0.50% of the principal amount of
the Old Sterling Senior Notes or the Accreted Value of the Old Sterling
Deferred Coupon Notes or the Old USD Deferred Coupon Notes, as applicable
(determined daily). The aggregate amount of special interest payable pursuant
to the above provisions will in no event exceed 1.50% per annum of the
principal amount of the Old Sterling Senior Notes or the Accreted Value of the
Old Sterling Deferred Coupon Notes or the Old USD Deferred Coupon Notes, as
applicable (determined daily). Upon the consummation of the Exchange Offer
after January 17, 1999, the special interest payable on the Old Notes from the
date of such consummation will cease to accrue and all accrued and unpaid
special interest as of the consummation of the Exchange Offer shall be paid
promptly thereafter to the holders of record of the Old Notes immediately
prior to the time of such occurrence. Following the consummation of the
Exchange Offer the interest terms shall revert to the original terms set forth
in the Notes.
 
  The New Sterling Senior Notes will bear interest from the most recent date
to which interest has been paid on the Old Sterling Senior Notes or, if no
interest has been paid on the Old Sterling Senior Notes, from March 13, 1998.
Accordingly, if the relevant record date for interest payment occurs after the
consummation of the
 
                                      32
<PAGE>
 
Exchange Offer, registered holders of New Sterling Senior Notes on such record
date will receive interest accruing from the most recent date to which
interest has been paid or, if no interest has been paid, from March 13, 1998.
If, however, the relevant record date for interest payment occurs prior to the
consummation of the Exchange Offer, registered holders of Old Sterling Senior
Notes on such record date will receive interest accruing from the most recent
date to which interest has been paid or, if no interest has been paid, from
March 13, 1998. Old Sterling Senior Notes accepted for exchange will cease to
accrue interest from and after the date of consummation of the Exchange Offer,
except as set forth in the immediately preceding sentence. Holders of Old
Sterling Senior Notes whose Old Sterling Senior Notes are accepted for
exchange will not receive any payment in respect of interest, if any, on such
Old Sterling Senior Notes otherwise payable on any interest payment date the
record date for which occurs on or after consummation of the Exchange Offer.
 
  In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-
Entry Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, the Letter of Transmittal properly completed and
duly executed or an Agent's Message in lieu thereof and all other required
documents. If any tendered Old Notes are not accepted for any reason set forth
in the terms and conditions of the Exchange Offer or if Old Notes are
submitted for an amount or quantity greater than the Holder desires to
exchange, such unaccepted or non-exchanged Old Notes will be returned without
expense to the tendering Holder thereof (or, in the case of Old Notes tendered
by book-entry transfer into the Exchange Agent's account at the Book-Entry
Transfer Facility pursuant to the book-entry procedures described below, such
non-exchanged Old Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration
or termination of the Exchange Offer.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will request the establishment of accounts with respect
to the Old Notes at the Book-Entry Transfer Facility 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 the Book-
Entry Transfer Facility suitable for the Exchange Offer, and any financial
institution that is a participant in the Book-Entry Transfer Facility's system
may make book-entry delivery of Old Notes by causing the Book-Entry Transfer
Facility to transfer such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for transfer.
 
  ALTHOUGH DELIVERY OF OLD NOTES MAY BE EFFECTED THROUGH BOOK-ENTRY TRANSFER
AT THE BOOK-ENTRY TRANSFER FACILITY, THE LETTER OF TRANSMITTAL (OR A FACSIMILE
THEREOF), WITH ANY REQUIRED SIGNATURE GUARANTEES OR AN AGENT'S MESSAGE IN LIEU
THEREOF AND ANY OTHER REQUIRED DOCUMENTS, MUST, IN ANY CASE, BE TRANSMITTED TO
AND RECEIVED BY THE EXCHANGE AGENT AT ONE OF THE ADDRESSES SET FORTH BELOW
UNDER "EXCHANGE AGENT," AS THE CASE MAY BE, ON OR PRIOR TO THE EXPIRATION DATE
OR THE GUARANTEED DELIVERY PROCEDURES DESCRIBED BELOW MUST BE COMPLIED WITH.
 
GUARANTEED DELIVERY PROCEDURES
 
  If a Holder of the Old Notes desires to tender such Old Notes and the Old
Notes are not immediately available, or time will not permit such Holder's Old
Notes or other required documents to reach the Exchange Agent before the
Expiration Date, or the procedure for book-entry transfer cannot be completed
on a timely basis, a tender may be effected if (i) the tender is made through
an Eligible Institution, (ii) prior to the Expiration Date, the Exchange Agent
received from such Eligible Institution the appropriate Notice of Guaranteed
delivery, substantially in the form provided by the Company (by telegram,
telex, facsimile transmission, mail or hand delivery), setting forth the name
and address of the Holder of Old Notes and the amount of Old Notes tendered,
stating that the tender is being made thereby and guaranteeing that within
five New York Stock Exchange ("NYSE") trading days after the
 
                                      33
<PAGE>
 
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 thereof or Agent's Message
in lieu thereof) 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 (iii) 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 thereof or
Agent's Message in lieu thereof) with any required signature guarantees, and
all other documents required by the Letter of Transmittal, are received by the
Exchange Agent within five NYSE trading days after the date of execution of
the Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
  Tenders of Old Notes may be withdrawn at any time prior to 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 such 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 Old Sterling
Senior Notes or the principal amount at maturity in the case of the Old
Sterling Deferred Coupon Notes or the Old USD Deferred Coupon Notes), and
(where certificates for Old Notes have been transmitted) specify the name in
which such 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, prior to the release of such
certificates the withdrawing Holder 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 such Holder is an
Eligible Institution. If Old Notes have been tendered pursuant to the
procedure for book-entry transfer described above, the executed notice of
withdrawal, guaranteed by an Eligible Institution, unless such Holder is an
Eligible Institution, must specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Old Notes and
otherwise comply with the procedures of such facility. All questions as to the
validity, form and eligibility (including time of receipt) of such notices
will be determined by the Company, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for exchange for purposes of the Exchange Offer. Any Old
Notes which have been tendered for exchange but which are not exchanged for
any reason will be returned to the Holder thereof without cost to such Holder
(or, in the case of Old Notes tendered by book-entry transfer into the
Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the
book-entry transfer procedures described above, such Old Notes will be
credited to an account maintained with such Book-Entry Transfer Facility for
the Old Notes) as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. 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 prior to the Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provision of the Exchange Offer, the Company shall
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 such Old Notes for exchange or the exchange of the
New Notes for such Old Notes any of the following events shall occur:
 
    (a) 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, (i) 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 thereof, or (ii) resulting in a material delay in the
  ability of the Company to accept for exchange or exchange some or all of
  the Old Notes pursuant to the Exchange Offer,
 
                                      34
<PAGE>
 
  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 the sole judgment of the Company might directly or indirectly
  result in any of the consequences referred to in clauses (i) or (ii) above
  or, on the sole judgement of the Company, 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
  Commission referred to on the cover page of this Prospectus, or would
  otherwise make it inadvisable to proceed with the Exchange Offer; or
 
    (b) there shall have occurred (i) 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, (ii) any limitation
  by any governmental agency or authority which may adversely affect the
  ability of the issuer to complete the transactions contemplated by the
  Exchange Offer, (iii) 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 (iv) 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 thereof; or
 
    (c) 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 the Company and its subsidiaries taken as a whole that, in the
  reasonable judgment of the Company, is or may be adverse to the Company, or
  the Company shall have become aware of facts that, in the reasonable
  judgment of the Company, have or may have adverse significance with respect
  to the value of the Old Notes or the New Notes;
 
which, in the reasonable judgment of the Company in any case, and regardless
of the circumstances (including any action by the Company) giving rise to any
such condition, makes it inadvisable to proceed with the Exchange Offer and/or
with such acceptance or exchange or with such exchange.
 
  The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any
such condition or may be waived by the Company in whole or in part at any time
and from time to time in its sole discretion. The failure by the Company at
any time to exercise any of the foregoing rights shall not be deemed a waiver
of any such right and each such right shall be deemed an ongoing right which
may be asserted at any time and from time to time.
 
  In addition, the Company 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 stop order shall be threatened or in effect with respect
to the Registration Statement of which this Prospectus constitutes a part or
the qualification of the Indentures under the Trust Indenture Act of 1939, as
amended (the "TIA").

DELIVERY OF THE LETTER OF TRANSMITTAL IN RESPECT OF THE NOTES TO AN ADDRESS

 .
 
 
FEES AND EXPENSES
 
  The Company will not make any payment to brokers, dealers, or others
soliciting acceptances of the Exchange Offer except for reimbursement of
mailing expenses.
 
  The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
$250,000.
 
TRANSFER TAXES
 
  Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith, except that holders who instruct
the Company to register New Notes in the name of, or request that Old Notes
not tendered or not accepted in the Exchange Offer be returned to, a person
other than the registered tendering holder will be responsible for the payment
of any applicable transfer tax thereon.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject, to the provisions
in the applicable Indenture regarding transfer and exchange of the Old Notes
and the restrictions on transfer of such Old Notes as set forth in the legend
on the Old Notes and as described in the Offering Memorandum as a consequence
of the issuance of such Old Notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities
Act and
applicable state securities laws. In general, the Old Notes may not be offered
or sold, unless registered under the
 
                                      36
<PAGE>
 
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not currently anticipate that it will take any action to register
the Old Notes under the Securities Act.
 
  Based on interpretations by the staff of the Commission, as set forth in no-
action letters issued to third parties, the Company believes that New Notes
issued in exchange of Old Notes, pursuant to the Exchange Offer may be offered
for resale, resold or otherwise transferred by Holders thereof (other than any
such Holder which is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such Holders' business and such
Holders, other than brokers-dealers, are not engaged in, do not intend to
engage in and have no arrangement or understanding with any person to
participate in, the distribution (within the meaning of the Securities Act) of
such New Notes. If any Holder has any arrangement or understanding with
respect to the distribution of the New Notes to be acquired pursuant to the
Exchange Offer, such Holder (i) could not rely on the applicable
interpretations of the staff of the Commission and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes must acknowledge that such
Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities and that it will deliver a prospectus
in connection with any resale of such New Notes. See "Plan of Distribution."
 
  In addition, to comply with the securities laws of certain jurisdictions, if
applicable, the New Notes may not be offered or sold unless they have been
registered or qualified for sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company
does not currently intend to take any action to register or qualify the sale
of the New Notes in any such jurisdictions.

                                USE OF PROCEEDS
 
  The Company will not receive any cash proceeds from the exchange of Old
Notes for New Notes pursuant to the Exchange Offer. The Company intends to use
the approximately $1.25 billion net proceeds to the Company from the sale of
the Old Notes to finance the construction, capital expenditure and working
capital requirements (including, without limitation, debt service and
repayment obligations) of the Company and, potentially, refinance existing
indebtedness. In addition a portion of the net proceeds may also be used to
make acquisitions of businesses or assets related to the Company's cable
telephony/television and telecommunications business.

(1) After giving retroactive effect to the four-for-three stock split by way
    of stock dividend paid in August 1995. For the year ended December 31,
    1997, net income (loss) per common share was $10.60 before extraordinary
    item.
(2) Fixed charges consist of interest expense, including capitalized interest,
    amortization of fees related to debt financing and rent expense deemed to
    be interest. The fixed charges coverage deficiency amounted to $94.6
    million, $355.4 million, $257.1 million, $105.4 million, $31.8 million and
    $10.4 million for the three months ended March 31, 1998 and for the years
    ended December 31, 1997, 1996, 1995, 1994 and 1993, respectively. For the
    three months ended March 31, 1998 and for the year ended December 31,
    1997, the Company's earnings were insufficient to cover combined fixed
    charges and preferred stock dividends by $98.2 million and $367.4 million.
 
The Company did not declare or pay any cash dividends during the years
  indicated.

                      UNAUDITED PRO FORMA FINANCIAL DATA
 
  The unaudited pro forma financial data presented herein gives effect to the
Amalgamation through which the Company will acquire all of the outstanding
capital stock of Partners. The pro forma financial data is based on the
historical financial statements of Partners and the Company. The balance sheet
data reflects the translation of all UK (Pounds) denominated amounts at the
March 31, 1998 rate of $1.6717 = (Pounds)1.00 The statements of operations
data reflects the translation of all UK (Pounds) denominated amounts at the
average rate for the three months ended March 31, 1998 and the year ended
December 31, 1997 of $1.6459 = (Pounds)1.00 and $1.638 = (Pounds)1.00,
respectively.
 
  The Amalgamation has been accounted for in the pro forma financial data
using the purchase method of accounting. Accordingly, Partners' assets
acquired and liabilities assumed have been recorded at their estimated fair
values, which are subject to further adjustment based upon appraisals and
other analyses, with appropriate recognition given to the Company's income tax
rates.
 
  Partners currently owns the Birmingham Cable Equity Interest and the Cable
London Equity Interest. Partners accounts for the Equity Interests using the
equity method. The following pro forma financial data gives effect to four of
the possible outcomes depending upon whether TeleWest determines to exercise
either or both of the Purchase Rights: (i) Partners retains both Equity
Interests; (ii) Partners retains the Cable London Equity Interest but not the
Birmingham Cable Equity Interest; (iii) Partners retains the Birmingham Cable
Equity Interest but not the Cable London Equity Interest; and (iv) Partners
does not retain either Equity Interest. The pro forma financial data assumes
that (i) the Purchase Rights are either resolved or exercised as of the
Determination Time and (ii) if either or both of the Purchase Rights are
exercised, the relevant Equity Interest proceeds will be paid by the Company
in cash and not in shares of the Company's Common Stock.
 
  The consummation of the Amalgamation requires the consent of certain third
parties. The pro forma financial data assumes that such consents will be
obtained. In the event that the Company or Partners makes cash payments or
gives other consideration in exchange for consents, the consideration will be
accounted for as additional deferred financing costs and amortized over the
remaining term of the debt.
 
  The pro forma financial data does not give effect to the issuance by the
Company in March 1998 of the Old Notes, for which the Company received net
proceeds of approximately $1.25 billion after discounts, commissions and
expenses. Interest expense would have increased by $29.4 million and $131.4
million for the three months ended March 31, 1998 and the year ended December
31, 1997, respectively.
 
  The unaudited pro forma condensed combined statement of operations for the
three months ended March 31, 1998 and for the year ended December 31, 1997
gives effect to the Amalgamation as if it had been consummated on January 1,
1997. The unaudited pro forma condensed combined balance sheet as of March 31,
1998 gives effect to the Amalgamation as if it had been consummated on March
31, 1998.
 
  The pro forma adjustments are based upon available information and
assumptions that management of the Company and Partners believes are
reasonable at the time made. The unaudited pro forma condensed combined
financial statements do not purport to present the financial position or
results of operations of the Company had the Amalgamation occurred on the
dates specified, nor are they necessarily indicative of the financial position
or results of operations that may be achieved in the future. The unaudited pro
forma condensed combined statements of operations do not reflect any
adjustments for synergies that the Company expects to realize commencing upon

                             DESCRIPTION OF NOTES
 
GENERAL
 
  Each class of New Notes offered hereby will be issued pursuant to its
respective Indenture, each dated as of March 13, 1998, each between the
Company and The Chase Manhattan Bank, as trustee (the "Trustee"). The
Indenture will be subject to the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act"). The following summary of certain provisions of the
Indentures, which have been filed as exhibits to the Registration Statement of
which this Prospectus forms a part, does not purport to be complete and is
qualified in its entirety by reference to the Indentures. The Indentures do
not purport to be complete and are subject to, and qualified in their entirety
by reference to the Trust Indenture Act, and to all provisions of the
Indentures, including the definition of certain terms therein and those terms
made part of the Indentures by reference to the Trust Indenture Act, as in
effect on the date of the Indentures. The definitions of certain terms used in
the following summary are set forth below under "--Certain Definitions." In
this "Description of Notes," the term "Company" refers to NTL Incorporated and
not any of its Subsidiaries.
 
  The Old Notes are, and the New Notes will be unsecured obligations of the
Company, ranking pari passu in right of payment with each other and with all
senior unsecured Indebtedness of the Company and senior in right of payment to
all subordinated Indebtedness of the Company.
 
  The operations of the Company are conducted through its Subsidiaries and,
therefore, the Company 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 such
Subsidiaries with respect to the cash flow and assets of those Subsidiaries.
 
  The Trustee will authenticate and deliver from time to time New Notes for
original issue only in exchange for (i) a like principal amount of Old
Sterling Senior Notes, or (ii) a like principal amount at maturity of Old
Sterling Deferred Coupon Notes or Old USD Deferred Coupon Notes, as
applicable.
 
  Any Old Notes of a class that remain outstanding after the completion of the
Exchange Offer, together with the New Notes of such class issued in connection
with the Exchange Offer, will be treated as a single class of securities under
the applicable Indenture.
 
  Application has been made to list the New Notes on the Luxembourg Stock
Exchange.
 
PRINCIPAL, MATURITY AND INTEREST
 
  The New Sterling Senior Notes will be limited in aggregate principal amount
to (Pounds)125,000,000. The New Sterling Senior Notes will accrue interest at
the rate of 9.5% per annum and will be payable semiannually on April 1 and
October 1 of each year, beginning on October 1, 1998, to the holders of record
on the immediately preceding March 15 and September 15, respectively. Interest
on the New Sterling Senior Notes will accrue from the most recent date to
which interest has been paid on the Old Sterling Senior Notes or, if no
interest has been paid on the Old Notes, from March 13, 1998. The New Sterling
Deferred Coupon Notes and the New USD Deferred Coupon Notes will be limited in
aggregate principal amount at maturity to (Pounds)300,000,000 and
$1,300,000,000, respectively. The Old Sterling Deferred Coupon Notes and the
Old USD Deferred Coupon Notes were each issued at a substantial discount from
their principal amounts at maturity. Until April 1, 2003, no interest will
accrue on the New Sterling Deferred Coupon Notes and the New USD Deferred
Coupon Notes, but the Accreted Value of each of the New Sterling Deferred
Coupon Notes and the New USD Deferred Coupon Notes will increase (representing
amortization of original issue discount) between March 13, 1998 and April 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 New Sterling
Deferred Coupon Notes or the New USD Deferred Coupon Notes, as the case may
be, shall be equal to the full principal amount at maturity of the New
Sterling Deferred Coupon Notes or the New USD Deferred Coupon Notes, as the
case may be, on April 1, 2003. Commencing April 1, 2003, interest on each of
the New Sterling Deferred Coupon Notes and the New USD Deferred Coupon Notes
 
                                      46
<PAGE>
 
will accrue at rates of 10.75% per annum and 9.75% per annum, respectively,
and will be payable in cash, semiannually in arrears, on each April 1 and
October 1, commencing October 1, 2003, to holders of record on the immediately
preceding March 15 and September 15. 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 applicable 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 principal in respect of the New Notes includes 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 the Company maintained for such purpose within the City and State
of New York and London, England and, so long as the New Notes are listed on
the Luxembourg Stock Exchange, at the office of the paying agent maintained in
Luxembourg or, at the option of the Company, 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 the Company and the Trustee. Until
otherwise designated by the Company, the Company's office or agency in New
York and London, respectively, will be the offices of the Trustee maintained
for such purpose. The Company has designated Banque Internationale a
Luxembourg to act as paying agent in Luxembourg. Each of the New Notes will be
payable on maturity on April 1, 2008 at 100% of its principal amount and will
be issued in registered form, without coupons, and in denominations of
(Pounds)1,000 or $1,000, as applicable, and integral multiples thereof.
 
OPTIONAL REDEMPTION
 
  Except as referred to herein under "--Covenants--Additional Amounts;
Optional Tax Redemption," the Notes are not redeemable at the Company's option
prior to April 1, 2003. Thereafter, the Notes will be subject to redemption at
the option of the Company, in whole or in part, upon not less than 30 nor more
than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest thereon to
the applicable redemption date, if redeemed during the twelve-month period
beginning on April 1 of the years indicated below:

Notes shall be made at the redemption prices specified in the applicable
Indentures plus accrued and unpaid interest, if any, to the applicable

SUBSTITUTION OF CURRENCY
 
  Although there can be no assurance that a single European currency will be
adopted or, if adopted, on what time schedule, the Treaty on the European
Economic and Monetary Union provides for the introduction of the Euro in
substitution for the national currencies of the member states which adopt the
Euro. If the United Kingdom adopts the Euro, the regulations of the European
Commission relating to the Euro shall apply to each of the Sterling Senior
Notes, the Sterling Deferred Coupon Notes, the Sterling Senior Notes Indenture
and the Sterling Deferred Coupon Notes Indenture. The circumstances and
consequences described in this paragraph entitle neither the Company nor any
holder of the Sterling Senior Notes or Sterling Deferred Coupon Notes to early
redemption, rescission, notice or repudiation of the terms and conditions of
the Sterling Senior Notes or Sterling Deferred Coupon Notes or the applicable
Indentures or to raise other defenses or to request any compensation claim,
nor will they affect any of the other obligations of the Company under the
Sterling Senior Notes or Sterling Deferred Coupon Notes and the applicable
Indentures.

MANDATORY REDEMPTION AND REPURCHASE
 
  The Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes. The Company is required to make a Change
of Control Offer (as defined below) and an Asset Sale Offer (as defined below)
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
 
  Upon the occurrence of a Change of Control Triggering Event, each holder of
Notes shall have the right to require the Company to repurchase all or any
part (equal to (Pounds)1,000 or $1,000, as applicable, or an integral multiple
thereof) of such holder's Notes pursuant to the offer described below (the
"Change of Control Offer") at a purchase price equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the date of
purchase (or, in the case of repurchases of Sterling Deferred Coupon Notes or
USD Deferred Coupon Notes prior to April 1, 2003, at a purchase price equal to
101% of the Accreted Value thereof as of the date of purchase) (the "Change of
Control Payment"). Within 40 days following any Change of Control Triggering
Event, the Company shall mail a notice to each holder, 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 (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 Sterling
Deferred Coupon Notes and USD Deferred Coupon Notes not tendered will continue
to increase as provided in such Notes); (4) that, unless the Company 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 applicable, the Accreted
Value of any Sterling Deferred Coupon Notes and USD Deferred Coupon Notes
tendered will cease to increase as provided in such 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 Notes equal in
principal amount to the unpurchased portion of the Notes surrendered, which
unpurchased portion must be equal to (Pounds)1,000 or $1,000 in principal
amount, as applicable, or an integral multiple thereof.
 
  The Company will comply with the requirements of Rules 13e-4 and 14e-1 under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and any
other securities laws and regulations thereunder to the extent such 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, the Company will, to the extent
lawful, (1) accept for payment Notes or portions thereof 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 thereof
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 thereof tendered to the Company. 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 the Company and the Paying Agent) payment in an
amount equal to the purchase price for such Notes, and 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 (Pounds)1,000 or
$1,000, as applicable, or an integral multiple
 
                                      48
<PAGE>
 
thereof. The Company 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 the Company repurchase or redeem the
Notes in the event of a takeover, 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 such covenant is, however, subject to certain
exceptions which may permit the Company to be involved in such 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 the Company,
and, thus, the removal of incumbent management. The Change of Control Offer
requirement, however, is not the result of management's knowledge of any
specific effort to accumulate the Company's stock or to obtain control of the
Company by means of a merger, tender offer, solicitation or otherwise, or part
of a plan by management to adopt a series of anti-takeover provisions.
Instead, the Change of Control Offer requirement is a result of negotiations
between the Company and the Initial Purchasers. Management has not entered
into any agreement or plan involving a Change of Control, although it is
possible that the Company would decide to do so in the future. Subject to the
limitations discussed below, the Company could, in the future, enter into
certain 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 the Company's capital structure
or credit ratings.
 
  The indentures for the 10% Notes, in an aggregate principal amount at
maturity of $400,000,000, the 10 7/8% Notes, in an aggregate principal amount
at maturity of $212,000,000, the 12 3/4% Notes, in an aggregate principal
amount at maturity of $277,803,500, and the 11 1/2% Notes, in an aggregate
principal amount at maturity of $1,050,000,000, which rank pari passu with the
Notes, also contain change of control provisions. The indentures for the
Convertible Notes, which are subordinated to the Notes, also contain change of
control provisions.
 
  The Company's ability to pay cash to the holders of Notes pursuant to a
Change of Control Offer may be limited by the Company's then existing
financial resources. See "Risk Factors--Potential Adverse Consequences of
Leverage" and "--Holding Company Structure; Dependence Upon Cash Flow from
Subsidiaries." The Credit Facility does, and any future credit agreements or
other agreements relating to indebtedness of the Company may, contain
prohibitions or restrictions on the Company'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, the Company 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 the Company does
not obtain such a consent or repay such borrowings, the Company will be
effectively prohibited from purchasing Notes. In such case, the Company'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 the Company or the Company'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 the Company's Subsidiaries. Any such
enforcement may limit the Company's ability to raise cash to repay or
repurchase the Notes.
 
  The Company will not be required to make a Change of Control Offer in the
event the Company enters into a transaction with management or their
affiliates who are Permitted Holders. The definition of Change of Control
includes a phrase relating to the sale, lease, transfer, conveyance or other
disposition of "all or substantially all"
 
                                      49
<PAGE>
 
of the Company'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 the Company to repurchase such Notes as a result of
a sale, lease, transfer, conveyance or other disposition of less than all of
the assets of the Company and its Subsidiaries to another Person may be
uncertain.
 
ASSET SALES
 
  The Indentures will provide that the Company will not and will not permit
any of its Restricted Subsidiaries to cause, make or suffer to exist any Asset
Sale, unless (i) no Default exists or is continuing immediately prior to and
after giving effect to such Asset Sale, (ii) the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of such
Asset Sale at least equal to the fair market value (evidenced for purposes of
this 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 (iii) at least 80% of the consideration therefor
received by the Company or such Restricted Subsidiary is in the form of (w)
Cash Equivalents, (x) Replacement Assets, (y) publicly traded Equity Interests
of a Person who is, directly or indirectly, engaged primarily in one or more
Cable Businesses; provided, however, that the Company or such Restricted
Subsidiary shall Monetize such Equity Interests by sale to one or more Persons
(other than to the Company or a Subsidiary thereof) at a price not less than
the fair market value thereof within 180 days of the consummation of such
Asset Sale, or (z) any combination of the foregoing clauses (w) through (y);
provided, however, that the amount of (x) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet or in the
notes thereto), of the Company or any Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Notes) that are
assumed by the transferee of any such assets and (y) any notes or other
obligations received by the Company or any such Restricted Subsidiary from
such transferee that are within five Business Days converted by the Company or
such Restricted Subsidiary into cash, shall be deemed to be Cash Equivalents
(to the extent of the Cash Equivalents received in such conversion) for
purposes of this clause (iii).
 
  Within 360 days after any Asset Sale, the Company (or the Restricted
Subsidiary, as the case may be) will cause the Net Proceeds from such Asset
Sale (i) to be used to permanently reduce Indebtedness of a Restricted
Subsidiary or (ii) to be invested or reinvested in Replacement Assets. Pending
final application of any such Net Proceeds, the Company may temporarily reduce
revolving credit borrowings or otherwise invest such Net Proceeds in any
manner that is not prohibited by the applicable 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, the Company will make an offer (an "Asset
Sale Offer") to all holders of Notes and Other Qualified Notes to purchase the
maximum principal amount of Notes and Other Qualified Notes (determined on a
pro rata basis according to the accreted value or principal amount, as the
case may be, of the Notes and the Other Qualified Notes; provided, however,
that the Asset Sale Offer must be made first to the holders of the Applicable
Notes) that may be purchased out of the Excess Proceeds, if any, remaining
after the consummation of the aforementioned Asset Sale Offer to the holders
of the Applicable Notes (x) with respect to the Other Qualified Notes, based
on the terms set forth in the indenture related to each issue of the Other
Qualified Notes and (y) with respect to the Notes, at an offer price in cash
in an amount equal to 100% of the 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 Sterling Deferred Coupon Notes or USD
Deferred Coupon Notes prior to April 1, 2003, at a purchase price equal to
100% of the Accreted Value thereof 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, if any, remaining after the consummation of the
aforementioned Asset Sale Offer to the holders of the Applicable Notes, the
Company may use such deficiency for general corporate purposes. If the
aggregate principal amount or accreted value, as the case may be, of Notes and
Other Qualified Notes surrendered by holders thereof exceeds the amount of
Excess Proceeds, if any, remaining after the consummation of the
aforementioned Asset Sale Offer to the holders of the Applicable Notes, then
such remaining Excess Proceeds will be allocated pro rata according to
accreted value or principal amount,
 
                                      50
<PAGE>
 
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 Applicable Notes
and the Notes and the Other Qualified Notes, the amount of Excess Proceeds
will be reset at zero. No such Asset Sale Offer to purchase the Notes and
Other Qualified Notes shall be required to be made by the Company pursuant to
the foregoing provisions if there are no Excess Proceeds remaining after the
consummation of the Asset Sale Offer made to holders of the Applicable Notes.
 
  Notwithstanding the foregoing, the Company and its Subsidiaries may (i)
sell, lease, transfer, convey or otherwise dispose of assets or property
acquired after October 14, 1993, by the Company or any Subsidiary in a sale-
and-leaseback transaction so long as the proceeds of such sale are applied
within five Business Days to permanently reduce Indebtedness of a Restricted
Subsidiary or if there is no such Indebtedness or such proceeds exceed the
amount of such Indebtedness then such proceeds or excess proceeds are
reinvested in Replacement Assets within 360 days after such sale, lease,
transfer, conveyance or disposition, (ii)(x) swap or exchange assets or
property with a Cable Controlled Subsidiary or (y) issue, sell, lease,
transfer, convey or otherwise dispose of equity securities of any of the
Company's Subsidiaries to a Cable Controlled Subsidiary, in each of cases (x)
and (y) so long as (A) the ratio of Indebtedness to Annualized Pro Forma
EBITDA of the Company after such transaction is equal to or less than the
ratio of Indebtedness to Annualized Pro Forma EBITDA of the Company
immediately preceding such transaction; provided, however, that if the ratio
of Indebtedness to Annualized Pro Forma EBITDA of the Company immediately
preceding such transaction is 6:1 or less, then the ratio of Indebtedness to
Annualized Pro Forma EBITDA of the Company may be 0.5 greater than such ratio
immediately preceding such transaction and (B) either (I) the assets so
contributed consist solely of a license to operate a Cable Business and the
Net Households covered by all of the licenses to operate cable and telephone
systems held by the Company and its Restricted Subsidiaries immediately after
and giving effect to such transaction equals or exceeds the number of Net
Households covered by all of the licenses to operate cable and telephone
systems held by the Company and its Restricted Subsidiaries immediately prior
to such transaction or (II) the assets so contributed consist solely of Cable
Assets and the value of the Capital Stock received, immediately after and
giving effect to such transaction, as determined by an investment banking firm
of recognized standing with knowledge of the Cable Business, equals or exceeds
the value of the Cable Assets exchanged for such Capital Stock, (iii) sell,
transfer or otherwise dispose of Long Distance/Microwave Assets, or (iv)
issue, sell, lease, transfer, convey or otherwise dispose of Equity Interests
of the Company (or any Capital Stock Sales Proceeds therefrom) to any Person
(including Non-Restricted Subsidiaries).
 
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, or, in
the absence of such requirements or if the Notes are not so listed, on a pro
rata basis, provided that no Notes of (Pounds)1,000 or $1,000, as applicable,
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 Sterling Deferred Coupon Notes
and USD Deferred Coupon Notes tendered will cease to increase as provided in
such Notes), on Notes or portions of them called for redemption.
 
CERTAIN COVENANTS
 
Restricted Payments
 
  The Indentures will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or
pay any dividend or make any distribution on account of the Company's or any
of its Restricted Subsidiaries' Equity Interests (other than (x) dividends or
distributions payable in Equity
 
                                      51
<PAGE>
 
Interests (other than Disqualified Stock) of the Company or such Restricted
Subsidiary or (y) dividends or distributions payable to the Company or any
Wholly Owned Subsidiary of the Company, or (z) pro rata dividends or pro rata
distributions payable by a Restricted Subsidiary); (ii) purchase, redeem or
otherwise acquire or retire for value any Equity Interests of the Company
(other than any such Equity Interests owned by the Company or any Wholly Owned
Subsidiary of the Company); (iii) voluntarily purchase, redeem or otherwise
acquire or retire for value any Indebtedness that is subordinated to the
Notes; or (iv) make any Restricted Investment (all such payments and other
actions set forth in clauses (i) through (iv) above being collectively
referred to as "Restricted Payments"), unless, 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 the Company and its Restricted Subsidiaries
  after the Issuance Date (including Restricted Payments permitted by clauses
  (ii) through (ix) of the next succeeding paragraph), is less than the sum
  of (x) the difference between Cumulative EBITDA and 1.5 times Cumulative
  Interest Expense plus (y) Capital Stock Sale Proceeds plus (z) cash
  received by the Company or a Restricted Subsidiary from a Non-Restricted
  Subsidiary (other than cash which is or is required to be repaid or
  returned to such Non-Restricted Subsidiary); provided, however, that to the
  extent that any Restricted Investment that was made after the date of the
  Indentures is sold for cash or otherwise liquidated or repaid for cash, the
  amount credited pursuant to this clause (z) shall be the lesser of (A) the
  cash received with respect to such sale, liquidation or repayment of such
  Restricted Investment (less the cost of such sale, liquidation or
  repayment, if any) and (B) the initial amount of such Restricted
  Investment, in each case as determined in good faith by the Company's Board
  of Directors.
 
  The foregoing provisions will not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
applicable Indenture; (ii) (x) the redemption, repurchase, retirement or other
acquisition of any Equity Interests of the Company or any Restricted
Subsidiary or (y) an Investment in any Person, in each case, in exchange for,
or out of the proceeds of, the substantially concurrent sale (other than to a
Restricted Subsidiary of the Company) of other Equity Interests (other than
any Disqualified Stock) of the Company provided that the Company delivers to
the Trustee: (1) with respect to any transaction involving in excess of $1
million, a resolution of the Board of Directors set forth in an Officers'
Certificate certifying that such transaction is approved by a majority of the
directors on the Board of Directors; and (2) with respect to any transaction
involving in excess of $25 million, an opinion as to the fairness to the
Company or such Subsidiary from a financial point of view issued by an
investment banking firm of national standing with high yield experience,
together with an Officers' Certificate to the effect that such opinion
complies with this clause (2), provided, that the amount of such proceeds from
the sale of such Equity Interests shall be excluded in each case from Capital
Stock Sale Proceeds for purposes of clause (b)(y), above; (iii) Investments by
the Company or any Restricted Subsidiary in a Non-Controlled Subsidiary which
(A) has no Indebtedness on a consolidated basis other than Indebtedness
incurred to finance the purchase of equipment used in a Cable Business, (B)
has no restrictions (other than restrictions imposed or permitted by the
Indentures or the indentures governing the Other Qualified Notes or the
Applicable Notes or any other instrument governing unsecured indebtedness of
the Company which is pari passu with the Notes) on its ability to pay
dividends or make any other distributions to the Company or any of its
Restricted Subsidiaries, (C) is or will be a Cable Business and (D) uses the
proceeds of such Investment for constructing a Cable Business or the working
capital needs of a Cable Business; (iv) the redemption, purchase, defeasance,
acquisition or retirement of Indebtedness that is subordinated to the Notes
(including premium, if any, and accrued and unpaid interest) made by exchange
for, or out of the proceeds of the substantially concurrent sale (other than
to a Restricted Subsidiary of the Company) of, (A) Equity Interests of the
Company provided, that the amount of such proceeds from the sale of such
Equity Interests shall be excluded in each case from Capital Stock Sale
Proceeds for purposes of clause (b)(y), above or (B) Refinancing Indebtedness
permitted to be incurred under the "Incurrence of Indebtedness and Issuance of
Preferred Stock" covenant; (v) Investments by the Company or any Restricted
Subsidiary in a Non-Controlled Subsidiary which is or will be a Cable Business
in an amount not
 
                                      52
<PAGE>
 
to exceed $80 million in the aggregate plus the sum of (x) cash received by
the Company or a Restricted Subsidiary from a Non-Restricted Subsidiary (other
than cash which is or is required to be repaid or returned to such Non-
Restricted Subsidiary) and (y) Capital Stock Sale Proceeds (excluding the
aggregate net sale proceeds to be received upon conversion of the Convertible
Subordinated Notes), provided, that the amount of such proceeds from the sale
of such Equity Interests shall be excluded in each case from Capital Stock
Sale Proceeds for purposes of clause (b)(y), above; (vi) Investments by the
Company or any Restricted Subsidiary in Permitted Non-Controlled Assets; (vii)
the extension by the Company or any Restricted Subsidiary of trade credit to a
Non-Restricted Subsidiary extended on usual and customary terms in the
ordinary course of business, provided that the aggregate amount of such trade
credit shall not exceed $25 million at any one time; (viii) the payment of
cash dividends on the Preferred Stock accruing on or after February 15, 2004
or any mandatory redemption or repurchase of the Preferred Stock, in each
case, in accordance with the Certificate of Designations therefor; and (ix)

  Any Investment in a Subsidiary (other than the issuance, transfer or other
conveyance of Equity Interests of the Company (or any Capital Stock Sales
Proceeds therefrom)) that is designated by the Board of Directors as a Non-
Restricted Subsidiary shall become a Restricted Payment made on the date of
such designation in the amount of the greater of (x) the book value of such
Subsidiary on the date such Subsidiary becomes a Non-Restricted Subsidiary and
(y) the fair market value of such Subsidiary on such date as determined (A) in
good faith by the Board of Directors of such Subsidiary if such fair market
value is determined to be less than $25 million and (B) by an investment
banking firm of national standing with high yield underwriting expertise if
such fair market value is determined to be in excess of $25 million.
 
  Not later than the fifth Business Day after making any Restricted Payment
(other than those referred to in sub-clause (vii) of the second paragraph
preceding this paragraph), the Company shall deliver to the Trustee an
Officers' Certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by the covenant
"Restricted Payments" were computed, which calculations may be based upon the
Company's latest available financial statements.
 
Incurrence of Indebtedness and Issuance of Preferred Stock
 
  The Indentures will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, create, incur,
issue, assume, guaranty or otherwise become directly or indirectly liable with
respect to (collectively, "incur") any Indebtedness (including Acquired Debt)
and that the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock that
is Disqualified Stock; provided, however, that the Company may incur
Indebtedness or issue shares of Disqualified Stock and any of its Restricted
Subsidiaries may issue shares of preferred stock that is Disqualified Stock if
after giving effect to such issuance or incurrence on a pro forma basis, the
sum of (x) Indebtedness of the Company and its Restricted Subsidiaries, on a
consolidated basis, (y) the liquidation value of outstanding preferred stock
of Restricted Subsidiaries and (z) the aggregate amount payable by the Company
and its Restricted Subsidiaries, on a consolidated basis, upon redemption of
Disqualified Stock to the extent such amount is not included in the preceding
clause (y) shall be less than the product of Annualized Pro Forma EBITDA for
the latest fiscal quarter for which internal financial statements are
available immediately preceding the date on which such additional Indebtedness
is incurred or such Disqualified Stock or preferred stock is issued multiplied
by 7.0, determined on a pro forma basis (including a pro forma application of
the net proceeds therefrom), as if the additional Indebtedness had been
incurred, or the Disqualified Stock or preferred stock had been issued, as the
case may be, at the beginning of such quarter.
 
  The foregoing limitations will not apply to (a) the incurrence by the
Company or any Restricted Subsidiary of Indebtedness pursuant to the Credit
Facility, (b) the issuance by any Restricted Subsidiary of preferred stock
(other than Disqualified Stock) to the Company, any Restricted Subsidiary of
the Company or the holders of Equity Interests in any Restricted Subsidiary on
a pro rata basis to such holders, (c) the incurrence of
 
                                      53
<PAGE>
 
Indebtedness or the issuance of preferred stock by the Company or any of its
Restricted Subsidiaries the proceeds of which 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 to any
License), the acquisition of Cable Assets or the Capital Stock of a Qualified
Subsidiary, (d) the incurrence by the Company or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount not
to exceed $50 million, (e) the incurrence by the Company or any Restricted
Subsidiary of any Permitted Acquired Debt, (f) the incurrence by the Company
or any Subsidiary of Indebtedness issued in exchange for, or the proceeds of
which are used to extend, refinance, renew, replace, or refund the Notes,
Existing Indebtedness or Indebtedness referred to in clauses (a), (b), (c),
(d) or (e) above or Indebtedness incurred pursuant to the preceding paragraph
(the "Refinancing Indebtedness"); provided, however, that (1) the principal
amount of, and any premium payable in respect of, such Refinancing
Indebtedness shall not exceed the principal amount of Indebtedness so
extended, refinanced, renewed, replaced or refunded (plus the amount of
reasonable expenses incurred in connection therewith); (2) the Refinancing
Indebtedness shall have (A) a Weighted Average Life to Maturity equal to or
greater than the Weighted Average Life to Maturity of, and (B) a stated
maturity no earlier than the stated maturity of, the Indebtedness being
extended, refinanced, renewed, replaced or refunded; and (3) the Refinancing
Indebtedness shall be subordinated in right of payment to the Notes as and to
the extent of the Indebtedness being extended, refinanced, renewed, replaced
or refunded, (g) the issuance of the Preferred Stock in lieu of payment of
cash interest on the Subordinated Debentures or the incurrence by the Company
of Indebtedness represented by the Subordinated Debentures upon the exchange
of the Preferred Stock in accordance with the Certificate of Designations
therefor, (h) Indebtedness under Exchange Rate Contracts, provided that such
Exchange Rate Contracts are related to payment obligations under Existing
Indebtedness or Indebtedness incurred under this paragraph or the preceding
paragraph that are being hedged thereby, and not for speculation and that the
aggregate notional amount under each such Exchange Rate Contract does not
exceed the aggregate payment obligations under such Indebtedness,
(i) Indebtedness under Interest Rate Agreements, provided that the obligations
under such agreements are related to payment obligations on Existing
Indebtedness or Indebtedness otherwise incurred pursuant to this paragraph or
the preceding paragraph, and not for speculation, (j) the incurrence of
Indebtedness between the Company and any Restricted Subsidiary, between or
among Restricted Subsidiaries and between any Restricted Subsidiary and other
holders of Equity Interests of 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 the
Company or a Restricted Subsidiary of the Company), such events shall be
deemed, in each case, to constitute the incurrence of such Indebtedness by the
Company or by a Restricted Subsidiary, as the case may be, at the time of such
event, and (k) Indebtedness of the Company and/or any Restricted Subsidiary in
respect of performance bonds of the Company or any Subsidiary or surety bonds
provided by the Company or any Restricted Subsidiary received in the ordinary
course of business in connection with the construction or 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 the Company and its Restricted Subsidiaries of the
Indebtedness of such Non-Restricted Subsidiary as of the time of such
redesignation to the extent such Indebtedness does not already constitute
Indebtedness of the Company or one of its Restricted Subsidiaries.
 
Liens
 
  The Indentures will provide that neither the Company nor any of its
Restricted Subsidiaries may directly or indirectly create, incur, assume or
suffer to exist any Lien on any asset now owned or hereafter acquired, or any
income or profits therefrom or assign or convey any right to receive income
therefrom, except: (i) Permitted Liens; (ii) Liens securing Indebtedness and
related obligations incurred under clauses (a), (b), (c), (d), (e), (h), (i)
and (k) of the second paragraph of the "Incurrence of Indebtedness and
Issuance of Preferred Stock" covenant; (iii) Liens on the assets acquired or
leased with the proceeds of Indebtedness permitted to be incurred under the
"Incurrence of Indebtedness and Issuance of Preferred Stock" covenant; and
(iv) Liens securing
 
                                      54
<PAGE>
 
Refinancing Indebtedness permitted to be incurred under the "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant; provided that the
Refinancing Indebtedness so issued and secured by such Lien shall not be
secured by any property or assets of the Company or any of its Restricted
Subsidiaries other than the property or assets subject to the Liens securing
such Indebtedness being refinanced.
 
Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries
 
  The Indentures will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or suffer to exist or become effective any encumbrance or
restriction on the ability of any Restricted Subsidiary to (a)(i) pay
dividends or make any other distributions to the Company or any of its
Subsidiaries (A) on its Capital Stock or (B) with respect to any other
interest or participation in, or measured by, its profits, or (ii) pay any
indebtedness owed to the Company or any of its Subsidiaries or (b) make loans
or advances to the Company or any of its Subsidiaries or (c) transfer any of
its properties or assets to the Company or any of its Subsidiaries, except for
such encumbrances or restrictions existing under or by reason of (i) Existing
Indebtedness as in effect on the Issuance Date, (ii) the Indentures and the
Notes, (iii) any agreement covering or relating to Indebtedness permitted to
be incurred under clause (a), (b), (c), (d), (e), (h) or (i) (but only, in the
case of clause (h) or (i), to the extent contemplated by the then-existing
Credit Facility) of the second paragraph of the "Incurrence of Indebtedness
and Issuance of Preferred Stock" covenant, provided that the provisions of
such agreement permit any action referred to in clause (a) above in aggregate
amounts sufficient to enable the payment of interest and principal and
mandatory repurchases pursuant to the terms of 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 (a) above if an event of
default under such agreement has occurred and is continuing or would occur as
a result of any such action; and (y) any such agreement may nevertheless
contain (I) restrictions limiting the payment of dividends or the making of
any other distributions to all or a portion of excess cash-flow (or any
similar formulation thereof) and (II) subordination provisions governing
Indebtedness owed to the Company or any Restricted Subsidiary, (iv) applicable
law, (v) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Subsidiaries as in effect at the time of
such acquisition (except to the extent such Indebtedness was incurred in
connection with such acquisition), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other
than the Person, or the property or assets of the Person, so acquired;
provided that the EBITDA of such Person is not taken into account in
determining whether such acquisition was permitted by the terms of the
Indentures, (vi) customary nonassignment provisions in leases entered into in
the ordinary course of business and consistent with past practices, (vii)
provisions of joint venture or stockholder agreements, so long as such
provisions are determined by a resolution of the Board of Directors to be, at
the time of such determination, customary for such agreements, (viii) with
respect to clause (c) above, purchase money obligations for property acquired
in the ordinary course of business or the provisions of any agreement with
respect to any Asset Sale (or transaction which, but for its size, would be an
Asset Sale), solely with respect to the assets being sold, or (ix) permitted
Refinancing Indebtedness, provided that the restrictions contained in the
agreements governing such Refinancing Indebtedness are determined by a
resolution of the Board of Directors to be no more restrictive than those
contained in the agreements governing the Indebtedness being refinanced.
 
Merger, Consolidation or Sale of Assets
 
  The Indentures will provide that the Company may not consolidate or merge
with or into (whether or not the Company is the surviving corporation), or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its properties or assets in one or more related
transactions to, another corporation, Person or entity unless (i) the Company
is the surviving corporation or the entity or the Person formed by or
surviving any such consolidation or merger (if other than the Company) 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; (ii) the entity or Person formed by or surviving any such
 
                                      55
<PAGE>
 
consolidation or merger (if other than the Company) or the entity or Person to
which such sale, assignment, transfer, lease, conveyance or other disposition
will have been 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 the Company, pursuant to a supplemental indenture in a form
reasonably satisfactory to the Trustee, under the Notes and the Indentures;
(iii) immediately after such transaction no Default or Event of Default
exists; (iv) the Company 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 the Company immediately
preceding the transaction provided, however, that if the ratio of Indebtedness
to Annualized Pro Forma EBITDA of the Company immediately preceding such
transaction is 6:1 or less, then the ratio of Indebtedness to Annualized Pro
Forma EBITDA of the Company may be 0.5 greater than such ratio immediately
preceding such transaction; and (v) such transaction would not result in the
loss of any material authorization or Material License of the Company or its
Subsidiaries.
 
Additional Amounts; Optional Tax Redemption
 
  The Indentures will provide that the "Payment of Additional Amounts"
provision therein, 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 therein, relating to the Company's option
to redeem the Notes under certain circumstances if Additional Amounts are
payable, apply to the Notes in certain circumstances. The provisions of the
Indenture relating to the payment of Additional Amounts will only apply in the
event that the Company becomes, or a successor to the Company is, a
corporation organized or existing under the laws of the United Kingdom, the
Netherlands, the Netherlands Antilles, Bermuda or the Cayman Islands. In such
circumstances, all payments made by the Company 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 the Company under the Notes, the Company will pay
or cause to be paid such additional amounts ("Additional Amounts") as may be
necessary in order that the net amounts received by a holder of the Notes
after such deduction or withholding shall be not less than the amounts
specified in the Notes to which the holder of such Notes is entitled;
provided, however, that the Company shall not be required to make any payment
of Additional Amounts for or on account of:
 
    (a) any tax, assessment or other governmental charge to the extent such
  tax, assessment or other governmental charge would not have been imposed
  but for (i) the existence of any present or former connection between such
  holder (or between a fiduciary, settlor, beneficiary, member or shareholder
  of, or possessor of a power over, such holder, if such holder is an estate,
  nominee, trust, partnership or corporation), other than the holding of 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 (ii) 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;
 
                                      56
<PAGE>
 
    (b) any tax, assessment or other 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 the Company 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;
 
    (c) any estate, inheritance, gift, sales, transfer, personal property or
  similar tax assessment or other governmental charge;
 
    (d) any tax assessment or other governmental charge which is collectible
  otherwise than by withholding from payments of principal amount, redemption
  amount, Change of Control Payment or interest with respect to a Note or
  withholding from the proceeds of a sale or exchange of a Note;
 
    (e) any tax, assessment or other governmental charge required to be
  withheld by any paying agent from any payment of principal amount,
  redemption amount, Change of Control Payment or interest with respect to a
  Note, if such payment can be made, and is in fact made, without such
  withholding by any other paying agent located inside the United States;
 
    (f) any tax, assessment or other governmental charge imposed on a holder
  that is not the beneficial owner of a 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;
 
    (g) any combination of items (a), (b), (c), (d), (e) and (f) above;
 
nor shall Additional Amounts be paid with respect to any payment of the
principal of, or any interest on 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 the Company, in whole but not in
part, upon not less than 30 nor more than 60 days notice, at any time at a
redemption price equal to the principal amount thereof plus accrued and unpaid
interest to the date fixed for redemption (or in the case of redemption of
Sterling Deferred Coupon Notes or USD Deferred Coupon Notes at a redemption
price equal to 100% of the Accreted Value thereof 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 (a "Change in Tax Law")
which becomes effective after the Issuance Date, as a result of which the
Company is or would be so required on the next succeeding Interest Payment
Date to pay Additional Amounts with respect to the 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) (a "Withholding Tax") and
such Withholding Tax is imposed at a rate that exceeds the rate (if any) at
which Withholding Tax was imposed on the Issuance Date provided, that, (i)
this paragraph shall not apply to the extent that, at the Relevant Date it was
known or would have been known had professional advice of a nationally
recognized accounting firm in the United Kingdom, 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,
(ii) no such notice of redemption may be given earlier than 90 days prior to
the earliest date on which the Company would be obliged to pay such Additional
Amounts were a payment in respect of the Notes then due, (iii) at the time
such notice of redemption is given, such obligation to pay such Additional
Amount remains in effect and (iv) the payment of such Additional Amounts
cannot be avoided by the use of any reasonable measures available to the
Company.
 
                                      57
<PAGE>
 
  The Notes may also be redeemed, in whole but not in part, at any time at a
redemption price equal to the principal amount thereof plus accrued and unpaid
interest to the date fixed for redemption if the person formed after the
Issuance Date by a consolidation, amalgamation, reorganization or
reconstruction (or other similar arrangement) of the Company or the person
into which the Company is merged after the Issuance Date or to which the
Company conveys, transfers or leases its properties and assets after the
Issuance substantially as an entirety (collectively, a "Subsequent
Consolidation") is required, as a consequence of such Subsequent Consolidation
and as a consequence of a Change in Tax Law in the United Kingdom, the
Netherlands, the Netherlands Antilles, Bermuda or the Cayman Islands occurring
after the date of such Subsequent Consolidation to pay Additional Amounts with
respect to 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,
provided, however, that this paragraph shall not apply to the extent that, at
the date of such Subsequent Consolidation it was known or would have been
known had professional advice of a nationally recognized accounting firm in
the United Kingdom, the Netherlands, the Netherlands Antilles, Bermuda or the
Cayman Islands, as the case may be, been sought, that a Change in Tax Law in
the United Kingdom, the Netherlands, the Netherlands Antilles, Bermuda or the
Cayman Islands, was to occur after such date.
 
  The Company will also pay, or make available for payment, to holders on the
redemption date any Additional Amounts resulting from the payment of such
redemption price.
 
Transactions with Affiliates
 
  The Indentures will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or amend any contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each of
the foregoing, an "Affiliate Transaction"), unless (a) such Affiliate
Transaction is on terms that are no less favorable to the Company or the
relevant Subsidiary than those that could have been obtained in a comparable
transaction by the Company or such Subsidiary with an unrelated Person and (b)
the Company delivers to the Trustee (i) with respect to any Affiliate
Transaction involving aggregate payments in excess of $1 million or any series
of Affiliate Transactions with an Affiliate involving aggregate payments in
excess of $1 million, a resolution of the Board of Directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (a) above and such Affiliate Transaction is approved by a majority of
the disinterested directors on the Board of Directors and (ii) with respect to
any Affiliate Transaction or any series of Affiliate Transactions involving
aggregate payments in excess of $25 million, an opinion as to the fairness to
the Company or such Subsidiary from a financial point of view issued by an
investment banking firm of national standing with high yield experience
together with an Officers' Certificate to the effect that such opinion
complies with this clause (ii); provided, however, that notwithstanding the
foregoing provisions, the following shall not be deemed to be Affiliate
Transactions: (i) any employment agreement entered into by the Company or any
of its Subsidiaries in the ordinary course of business and consistent with the
past practice of the Company or its predecessor or such Subsidiary; (ii)
transactions between or among the Company and/or its Restricted Subsidiaries;
(iii) transactions permitted by the provisions of the Indentures described
above under the covenant "Restricted Payments"; (iv) Liens permitted under the
Liens covenant which are granted by the Company or any of its Subsidiaries to
an unrelated Person for the benefit of the Company or any other Subsidiary of
the Company; (v) any transaction pursuant to an agreement in effect on the
Issuance Date; (vi) 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; (vii) management, operating, service or
interconnect agreements entered into in the ordinary course of business with
any Cable Business in which the Company or any Restricted Subsidiary has an
Investment and which is not a Cable Controlled Subsidiary (and of which no
Affiliate of the Company is an Affiliate other than as a result of such
Investment); and (viii) any tax sharing agreement.
 
Reports
 
  Whether or not required by the rules and regulations of the Commission, so
long as any Notes are outstanding, the Company will file with the Commission
and furnish to the holders of Notes all quarterly and
 
                                      58
<PAGE>
 
annual financial information required to be contained in a filing with the
Commission on Forms 10-Q and 10-K (or the equivalent thereof under the
Exchange Act for foreign private issuers in the event the Company becomes a
corporation organized under the laws of the United Kingdom, the Netherlands,
the Netherlands Antilles, Bermuda or the Cayman Islands), including a
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" and, with respect to the annual information only, a report thereon
by the Company's certified independent accountants, in each case, as required
by the rules and regulations of the Commission as in effect on the Issuance
Date. As long as the Notes are listed on the Luxembourg Stock Exchange, copies
of such reports will also be available at the specified office of the listing,
paying and transfer agent in Luxembourg. The Company does not publish
unconsolidated financial reports.
 
EVENTS OF DEFAULT AND REMEDIES
 
  The Indentures will provide that each of the following constitutes an Event
of Default: (i) default for 30 days in the payment when due of interest (and
Additional Amounts, if applicable) on the Notes; (ii) default in payment when
due of principal on the Notes; (iii) failure by the Company to comply with the
provisions described under the covenants "Change of Control," "Restricted
Payments" or "Incurrence of Indebtedness and Issuance of Preferred Stock";
(iv) failure by the Company for 60 days after notice to comply with certain
other covenants and agreements contained in the Indentures or the Notes; (v)
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 the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company 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 failure continues beyond any
applicable grace period) (a "Payment Default") 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; (vi) failure by the Company or any Restricted Subsidiary
of the Company 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; (vii) certain events of bankruptcy or insolvency with respect to the
Company or any of its Material Subsidiaries; and (viii) 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 each then outstanding class of Notes
may declare all the applicable class of 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 the
Company 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 each then
outstanding class of 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 Indentures except a continuing Default
or Event of Default in the payment of interest on, or the principal of, the
applicable class of Notes.
 
  The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indentures, and the Company 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 the Company,
as such, shall have any liability for any Obligations of the Company under the
Notes or the Indentures or for any claim based on, in respect of,
 
                                      59
<PAGE>
 
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 INDENTURES AND THE NOTES
 
  If the Company 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 a class of Notes or the date of redemption of all the outstanding Notes of
such class, as 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 of such class and all interest due thereon
to maturity or redemption, the applicable Indenture shall cease to be of
further effect as to all outstanding Notes of such class ("Defeasance")
(except, among other things, as to (i) remaining rights of registration of
transfer and substitution and exchange of the Notes of such class, (ii) rights
of holders to receive payment of principal of (or, if applicable, payments in
respect of Accreted Value) and interest on the Notes of such class, and (iii)
the rights, obligations and immunities of the Trustee).
 
  In order to exercise Defeasance: (i) the Company shall have delivered to the
Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming
that (A) the Company has received from, or there has been published by, the
Internal Revenue Service, a ruling or (B) since the 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 of the applicable
class 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; (ii) 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; (iii) 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 the Company or any of its Subsidiaries is a party
or by which the Company or any of its Subsidiaries is bound; (iv) the Company
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; (v) the Company shall have
delivered to the Trustee an Officers' Certificate stating that the deposit was
not made by the Company with the intent of preferring the holders of Notes
over the other creditors of the Company with the intent of defeating,
hindering, delaying or defrauding creditors of the Company or others; (vi) the
deposit shall not result in the Company, the Trustee or the trust being
subject to the Investment Company Act of 1940; (vii) holders of the Notes of
the applicable class will have a valid, perfected and unavoidable (under
applicable bankruptcy or insolvency laws), subject to the passage of time
referred to in clause (iv) above, first priority security interest in the
trust funds; and (viii) the Company 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 the Company at its written request.
After that, holders of Notes entitled to the money must look to the Company
for payment unless an abandoned property law designates another person and all
liability of the Trustee and such Paying Agent shall cease. Other than as set
forth in this paragraph, the Indentures do not provide for any prescription
period for the payment of interest and principal on the Notes.
 
                                      60

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 the Company may require a holder to
pay any taxes and fees required by law or permitted by the Indentures. The
Company is not required to transfer or exchange any Note selected for
redemption. Also, the Company 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
such Indenture applies (including consents obtained in connection with a
tender offer or exchange offer for such Notes), and any existing default or
compliance with any provision of any Indenture or class of Notes may be waived
with the consent of the holders of a majority in principal amount of the then
outstanding Notes to which such Indenture applies (including consents obtained
in connection with a tender offer or exchange offer for such Notes).
 
  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) (i)
reduce the amount of Notes whose holders must consent to an amendment,
supplement or waiver, (ii) reduce the principal of or change the fixed
maturity of any Note or alter the provisions with respect to the redemption of
the Notes (but not any required repurchases of the Notes pursuant to the
covenants described above under the captions "--Asset Sales" and "--Change of
Control"), (iii) reduce the rate of or change the time for payment of interest
on any Note, (iv) 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), (v) make any
Note payable in money other than that stated in the Notes, (vi) make any
change in the provisions of any 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, (vii) waive a redemption payment with respect to any
Note or (viii) make any change in the foregoing amendment and waiver
provisions.
 
  Notwithstanding the foregoing, without the consent of any holder of Notes,
the Company 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 the Company'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 any 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, 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 AND JUDGMENTS
 
  The Notes and the Indentures will be governed exclusively by the laws of the
State of New York. Under the Judiciary Law of the State of New York, a
judgment or decree in an action based upon an obligation
 
                                      61
<PAGE>
 
denominated in a currency other than U.S. dollars will be rendered in the
foreign currency of the underlying obligation and converted into U.S. dollars
at a rate of exchange prevailing on the date of the entry of the judgment or
decree.
 
CONCERNING THE TRUSTEE
 
  The Indentures contain limitations on the rights of the Trustee, should it
become a creditor of the Company, 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 Indentures 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.

                              REGISTRATION RIGHTS
 
  The following summary of the registration rights provided in the
Registration Rights Agreements and the Old Notes does not purport to be
complete. It is qualified in its entirety by reference to the terms of the
registration rights set forth in the Registration Rights Agreements and the
Old Notes.
 
  Holders of New Notes are not generally entitled to any registration rights
with respect to such New Notes. Pursuant to the Registration Rights
Agreements, holders of Old Notes are entitled to certain registration rights.
Pursuant to the Registration Rights Agreements, the Company agreed to file
with the Commission a registration statement, including a prospectus, (the
"Exchange Offer Registration Statement") 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. Upon the
effectiveness of the Exchange Offer Registration Statement, the Company will
offer to the holders of Transfer Restricted Securities pursuant to the
Exchange Offer, who are able to make certain representations with respect to
the applicable class of Old Notes, the opportunity to exchange their Transfer
Restricted Securities for New Notes of the applicable class. If (i) with
respect to any class of the Old Notes the Company is 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
Commission policy or (ii) any holder of Transfer Restricted Notes notifies the
Company within the specified time period that (A) it is prohibited by law or
Commission 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 the Company or an affiliate of the Company, the Company will file with
the Commission a shelf registration statement (a "Shelf Registration
Statement") to cover resales of the applicable Old Notes by the holders
thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. The Company
will use its best efforts to cause the applicable Registration Statement to be
declared effective as promptly as possible by the Commission. For purposes of
the foregoing, "Transfer Restricted Notes" means each Old Note until (i) 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, (ii) 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 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, (iii) 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, (iv) the date on which
such Old Note is distributed to the public pursuant to Rule 144 under the Act
(or any similar provision then in effect) or is saleable pursuant to Rule
144(k) under the Act or (v) the date upon which such Old Note ceases to be
outstanding.
 
  The Registration Rights Agreements provide that (i) the Company will file an
Exchange Offer Registration Statement with the Commission on or prior to June
12, 1998, (ii) the Company will use its best efforts to have the Exchange
Offer Registration Statement declared effective by the Commission on or prior
to December 9, 1998, (iii) unless the Exchange Offer would not be permitted by
applicable law or Commission policy, the Company will commence the Exchange
Offer and use its best efforts to issue on or prior to January 18, 1999,
Exchange Notes in exchange for all Notes tendered prior thereto in the
Exchange Offer and (iv) if obligated to file the Shelf Registration Statement,
the Company will use its best efforts to file the Shelf Registration Statement
with the Commission as promptly as practicable after such filing obligation
arises and to cause the Shelf Registration to be declared effective by the
Commission on or prior to January 18, 1999. If, with respect to any class of
the Notes (a) the Company fails to file the Exchange Offer Registration
Statement on or before the date specified for such filing, (b) the Exchange
Offer Registration Statement is not declared effective on or prior to December
9, 1998 or (c) the Company fails to consummate the Exchange Offer, or a Shelf
Registration Statement is not declared effective, within the specified time
frames (each such event referred to in clauses (a) through (c) above a
"Registration Default"), then the Company will pay special interest pursuant
to provisions of the Old Note to each holder of the applicable Old Notes.
Special interest will accrue from and including (i) June 13,
 
                                      72
<PAGE>
 
1998 in the case of clause (i) above, (ii) December 10, 1998 in the case of
clause (ii) above, (iii) January 19, 1999 in the case of clause (iii) above or
(iv) January 19, 1999 in the case of clause (iv) above (each such period
referred to in clauses (i)-(iv) above an "Accrual Period"), at a rate per
annum equal to 0.50% of the principal amount of the Old Sterling Senior Notes
or the Accreted Value of the Old Sterling Deferred Coupon Notes or the Old USD
Deferred Coupon Notes, as applicable (determined daily). The amount of the
special interest will increase by an additional 0.50% of the principal amount
of the Old Sterling Senior Notes or the Accreted Value of the Old Sterling
Deferred Coupon Notes or the Old USD Deferred Coupon Notes, as applicable with
respect to each subsequent applicable Accrual Period until all Registration
Defaults have been cured, up to a maximum amount of special interest of 1.50%
per annum of the principal amount of the Old Sterling Senior Notes or the
Accreted Value of the Old Sterling Deferred Coupon Notes or the Old USD
Deferred Coupon Notes, as applicable (determined daily). All accrued special
interest will be paid by the Company 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 the Company fails
to keep such Registration Statement continuously effective for the period
required by the Registration Rights Agreement, then from such time as the
Shelf Registration Statement is no longer effective until the earlier of (i)
the date that the Shelf Registration Statement is again deemed effective, (ii)
March 13, 2000 or (iii) 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 Old Sterling Senior Notes or the Accreted
Value of the Old Sterling Deferred Coupon Notes or the Old USD Deferred Coupon
Notes, as applicable (determined daily) (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. The Company will be permitted to suspend use of
the prospectus that is part of any Shelf Registration Statement during certain
periods of time and in certain 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 the
Company (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.

THE 10 7/8% NOTES
 
  In October 1993, the Company issued its 10 7/8% Notes at a discount to their
aggregate principal amount to generate gross proceeds to the Company of
approximately $125 million. The 10 7/8% Notes accrete at a rate of 10 7/8%
compounded semi-annually to an aggregate principal amount of $212 million by
October 15, 1998. Interest does not accrue on the 10 7/8% Notes prior to
October 15, 1998. Thereafter, the 10 7/8% Notes accrue interest in cash at the
rate of 10 7/8% per annum on the principal amount payable semiannually on
October 15 and April 15, commencing on April 15, 1999, to holders of record on
the immediately preceding October 1 and April 1. The 10 7/8% Notes mature on
October 15, 2003. Except as described below, the 10 7/8% Notes will not be
redeemable prior to October 15, 1998. Thereafter, the 10 7/8% Notes are
redeemable, in whole or in part, at the option of the Company, at the
redemption prices set forth in the indenture pursuant to which the 10 7/8%
Notes were issued (the "10 7/8% Notes Indenture"), plus accrued and unpaid
interest to the date of redemption. In the event of a Change in Control (as
defined in the 10 7/8% Notes Indenture), each holder of 10 7/8% Notes has the
right to require the Company to repurchase its 10 7/8% Notes at a purchase
price equal to 101% of the Accreted Value thereof on any purchase date prior
to October 15, 1998, or 101% of the principal amount thereof plus accrued and
unpaid interest to any purchase date on or after October 15, 1998. Subject to
certain conditions, the Company will be obligated to offer to purchase the 10
7/8% Notes with the Excess Proceeds of certain Asset Sales
 
                                      74
<PAGE>
 
at a redemption price of 100% of the accreted value or, as the case may be,
principal amount thereof plus accrued and unpaid interest. The 10 7/8% Note
Indenture contains certain restrictions with respect to, among other things,
the payment of dividends, the repurchase of stock and the making of certain
other Restricted Payments, the incurrence of additional Indebtedness, the
creation of certain Liens, certain Asset Sales, transactions with subsidiaries
and other Affiliates and mergers and consolidations.
 
  In January 1996, the Company received the necessary consents of registered
holders of the 10 7/8% Notes to amend the 10 7/8% Notes Indenture so as to
allow the Company and its subsidiaries to take certain actions that were
previously prohibited under the 10 7/8% Notes Indenture, particularly
regarding the financing of the Company's and its subsidiaries' business and
future acquisitions. In addition, the amendment eliminated some, but not all,
of certain differences between the covenants in the 10 7/8% Notes Indenture
and the existing 12 3/4% Notes Indenture. On January 23, 1996, the Company and
Chemical Bank, now known as The Chase Manhattan Bank, as Trustee, executed a
first supplemental indenture to effect such amendment.
 
  The 10 7/8% Notes are senior unsecured obligations of the Company ranking
pari passu in right of payment of principal and interest with all other
existing and future senior unsecured obligations of the Company and rank
senior to all other existing and future subordinated debt of the Company,
including, without limitation, the Convertible Notes.
 
THE 12 3/4% NOTES
 
  In April 1995, concurrently with the offering of the 7 1/4% Convertible
Notes summarized below, the Company issued $277,803,500 aggregate principal
amount at maturity of its 12 3/4% Senior Deferred Coupon Notes Due 2005 (the
"Old 12 3/4% Notes") at a discount to their aggregate principal amount to
generate gross proceeds to the Company of approximately $150,000,000. The Old
12 3/4% Notes were issued and sold in a transaction exempt from the
registration requirement of the Securities Act pursuant to Rule 144A under the
Securities Act or in transactions complying with Regulation S under the
Securities Act. On August 18, 1995 the Company issued $277,803,500 aggregate
principal amount at maturity of the 12 3/4% Series A Senior Deferred Coupon
Notes Due 2005 (the "12 3/4% Notes") in exchange for the Old 12 3/4% Notes
pursuant to the indenture relating thereto (the "12 3/4% Notes Indenture").
The terms of the 12 3/4% Notes are identical in all material respects to the
Old 12 3/4% Notes except for certain transfer restrictions and registration
rights applicable to the Old 12 3/4% Notes. The Old 12 3/4% Notes were
cancelled on August 18, 1995 on consummation of the exchange offer which was
made pursuant to the Company's Prospectus dated July 18, 1995, forming part of
the Registration Statement on Form S-4 (File No. 33-92794) filed with the
Commission on May 26, 1995.
 
  The 12 3/4% Notes accrete at a rate of 12 3/4% computed on a semiannual bond
equivalent basis to an aggregate principal amount at maturity of $277,803,500.
Cash interest on the 12 3/4% Notes does not accrue until prior to April 15,
2000. Thereafter, the 12 3/4% Notes accrue interest in cash at the rate of 12
3/4% per annum on the principal amount payable semiannually on April 15 and
October 15 of each year, commencing October 15, 2000 to holders of record on
the immediately preceding April 1, and October 1. The 12 3/4% Notes mature on
April 15, 2005. The 12 3/4% Notes are redeemable, at the option of the Company
at any time, in whole or in part, on or after April 15, 2000 at the redemption
prices set forth in the 12 3/4% Notes Indenture, plus any unpaid interest, if
any, to the date of redemption. The 12 3/4% Notes may also be redeemed at the
option of the Company in whole but not in part in certain circumstances where
Additional Amounts (as defined in the 12 3/4% Notes Indenture) are payable
under the 12 3/4% Notes. In such circumstances the 12 3/4% Notes to be
repurchased must be repurchased at 100% of Accreted Value, or, as the case may
be, principal amount thereof. Upon a Change of Control (as defined in the 12
3/4% Notes Indenture), holders of the 12 3/4% Notes have the right to require
the Company to repurchase all or any part of the 12 3/4% Notes at a repurchase
price equal to 101% of the Accreted Value thereof plus accrued and unpaid
interest, if any. Subject to certain conditions, the Company is obligated to
offer to purchase the 12 3/4% Notes and other Qualified Senior Notes (as
defined in the 12 3/4% Notes Indenture) with the Excess Proceeds of certain
Asset Sales at a redemption price of 100% of the Accreted Value or, as the
case may be, principal amount thereof plus accrued and unpaid interest. The 12
3/4% Notes Indenture contains
 
                                      75
<PAGE>
 
certain restrictions with respect to, among other things, the payment of
dividends, the repurchase of stock and the making of certain other Restricted
Payments, the incurrence of additional Indebtedness, the creation of certain
Liens, certain Asset Sales, transactions with Subsidiaries and other
Affiliates and mergers and consolidations.
 
  The 12 3/4% Notes are senior unsecured obligations of the Company ranking
pari passu in right of payment of principal and interest with all other
existing and future senior unsecured obligations of the Company and rank
senior to all other existing and future subordinated debts of the Company,
including, without limitation, the Convertible Notes and the 7 1/4%
Convertible Notes.
 
  The Company has recently obtained the necessary consents of the registered
holders of the 12 3/4% Notes to certain proposed amendments to the 12 3/4%
Notes Indenture. On January 22, 1996, the Company and Chemical Bank, now known
as The Chase Manhattan Bank, as Trustee, executed a first supplemental
indenture to effect those amendments. In general, the amendments modify the 12
3/4% Notes Indenture by amending the covenant entitled "Limitations on
Dividend and Other Payment Restrictions Affecting Subsidiaries" and other
provisions to facilitate the arrangement of the Potential Credit Facilities
and other financings and make certain conforming and other changes to the 12
3/4% Notes Indenture.
 
  THE 11 1/2% NOTES
 
  In January 1996, the Company issued $1,050,000,000 aggregate principal
amount of maturity of its 11 1/2% Series A Senior Deferred Coupon Notes Due
2006 (the "Old 11 1/2% Notes") at a discount to their aggregate principal
amount to generate gross proceeds to the Company of approximately
$600,127,500. The Old 11 1/2% Notes were issued and sold in a transaction
exempt from the registration requirement of the Securities Act pursuant to
Rule 144A under the Securities Act. On May 23, 1996, the Company issued
$1,050,000,000 aggregate principal amount at maturity of the 11 1/2% Series B
Senior Deferred Coupon Notes Due 2006 (the "11 1/2% Notes") in exchange for
the Old 11 1/2% Notes pursuant to the Indenture relating thereto (the "11 1/2%
Notes Indenture"). The terms of the 11 1/2% Notes are identical in all
material respects to the Old 11 1/2% Notes except for certain transfer
restrictions and registration rights applicable to the Old 11 1/2% Notes. The
Old 11 1/2% Notes tendered for exchange were cancelled on May 23, 1996 on
consummation of the exchange offer made pursuant to the Company's Prospectus
dated April 22, 1996, forming part of the Company's Registration Statement on
Form S-4 (File No. 333-1010) filed with the Commission on April 16, 1996.
 
  The 11 1/2% Notes accrete at a rate of 11 1/2% computed on a semiannual bond
equivalent basis to an aggregate principal amount at maturity of
$1,050,000,000. Cash interest on the 11 1/2% Notes does not accrue until
February 1, 2001. Thereafter, the 11 1/2% Notes accrue interest in cash at the
rate of 11 1/2% per annum on the principal amount payable semiannually on
February 1 and August 1 of each year, commencing August 1, 2001, to holders of
record on the immediately preceding January 15, and July 15. The 11 1/2% Notes
mature on February 1, 2006. The 11 1/2% Notes are redeemable, at the option of
the Company at any time, in whole or in part, on or after February 1, 2001 at
the redemption prices set forth in the 11 1/2% Notes Indenture plus any
accrued unpaid interest to the date of redemption. The 11 1/2% Notes may also
be redeemed at the option of the Company in whole but not in certain
circumstances where "Additional Amounts" (as defined in the 11 1/2% Notes
Indenture) are payable under the 11 1/2% Notes. In such circumstances, the 11
1/2% Notes to be repurchased must be repurchased at 100% of accreted value or,
as the case may be, principal amount thereof plus accrued and unpaid interest.
Upon a Change of Control (as defined in the 11 1/2% Notes Indenture), holders
of the 11 1/2% Notes have the right to require the Company to repurchase all
or any part of the 11 1/2% Notes at a repurchase price equal to 101% of the
accreted value or, as the case may be, principal amount thereof plus accrued
and unpaid interest, if any. Subject to certain conditions, the Company is
obligated to offer to purchase the 11 1/2% Notes and other Qualified Senior
Notes (as defined in the 11 1/2% Notes Indenture) with the Excess Proceeds of
certain Asset Sales at a redemption price of 100% of the accreted value or, as
the case may be, principal amount thereof plus accrued and unpaid interest, if
any. The 11 1/2% Notes Indenture contains certain restrictions with respect
to, among other things, the payment of dividends, the repurchase of stock and
the making of certain other Restricted Payments, the incurrence of additional

THE 10% NOTES
 
  In February 1997, the Company issued $400,000,000 aggregate principal amount
of its 10% Series A Senior Notes Due 2007 (the "Old 10% Notes"). The Old 10%
Notes were issued and sold in a transaction exempt from the registration
requirement of the Securities Act pursuant to Rule 144A under the Securities
Act. On June 27, 1997 the Company issued $400,000,000 aggregate principal
amount at maturity of the 10% Series B Senior Notes Due 2007 (the "10% Notes")
in exchange for the Old 10% Notes pursuant to the indenture relating thereto
(the "10% Notes Indenture"). The terms of the 10% Notes are identical in all
material respects to the Old 10% Notes except for certain transfer
restrictions and registration rights applicable to the Old 10% Notes. The Old
10% Notes tendered for exchange were cancelled on June 27, 1997 on

dated May 27, 1997, forming part of the Company's Registration Statement on
Form S-4 (File No. 333-25577) filed with the Commission on April 21, 1997.
 
  The 10% Notes accrue interest in cash at the rate of 10% per annum on the
principal amount payable semiannually on February 15 and August 15 of each
year, to holders of record on the immediately preceding February 1, and August
1. The 10% Notes mature on February 15, 2007. The 10% Notes are redeemable, at
the option of the Company at any time, in whole or in part, on or after
February 15, 2002 are redemption prices set forth in the 10% Notes Indenture,
plus any accrued unpaid interest to the date of redemption. The 10% Notes may
also be redeemed at the option of the Company in whole but not in certain
circumstances where "Additional Amounts" (as defined in the 10% Notes
Indenture) are payable under the 10% Notes. In such circumstances, the 10%
Notes to be repurchased must be repurchased at 100% of the principal amount
thereof plus accrued and unpaid interest. Upon a Change of Control (as defined
in the 10% Notes Indenture), holders of the 10% Notes have the right to
require the Company to repurchase all or any part of the 10% Notes at a
repurchase price equal to 101% of the principal amount thereof plus accrued
and unpaid interest, if any. Subject to certain conditions, the Company is
obligated to offer to purchase the 10% Notes and other Qualified Senior Notes
(as defined in the 10% Notes Indenture) with the Excess Proceeds of certain
Asset Sales at a redemption price of 100% of the principal amount thereof plus
accrued and unpaid interest, if any. The 10% Notes Indenture contains certain

and future senior unsecured obligations of the Company and rank senior to all
other existing and future subordinated debt of the Company.
 
THE NEW CREDIT FACILITY
 
  In August 1997, NTL (UK) Group, Inc., a wholly-owned subsidiary of the
Company, which is the holding company for the United Kingdom operations and
the parent company of NTLIH, and NTLIH entered into an agreement with The
Chase Manhattan Bank pursuant to which Chase has agreed to fully underwrite an
(Pounds)875 million eight-year term loan facility with an initial four-year
revolving period (which amount is likely to be reduced as a result of the
Offering). The New Credit Facility will be used to finance capital
expenditures and working capital for the Company's United Kingdom operations,
including its local broadband, national telecommunications and national
digital television networks. A portion of the facility ((Pounds)75 million) is
conditional upon the execution of contracts to provide digital television
transmission services to certain third parties. Chase has provided a portion
of the New Credit Facility in the form of a (Pounds)350 million facility to
the Company on substantially the same terms as to restrictions, covenants,
guarantees and security as the New Credit Facility.
 
                                      77
<PAGE>
 
Prior to the Offering of the Old Notes, Chase had a commitment to increase the
amounts available to be borrowed thereunder to (Pounds)875 million. Upon
completion of the offering of the Old Notes, Chase's commitment under the New
Credit Facility was reduced to (Pounds)555 million. If a portion of proceeds
of the offering of the Old Notes is used for the repayment of existing
indebtedness in certain circumstances or, if such proceeds are not so used by
April 14, 1999, Chase's commitment will be further reduced to no less than
(Pounds)480 million or such greater amount as is necessary to ensure that the
Company's UK operations remain fully funded by reference to an agreed business
plan. At March 20, 1998, the Company had outstanding (Pounds)10 million of the
(Pounds)350 million currently available under the New Credit Facility. The
final maturity of the principal amount outstanding under the (Pounds)350
million facility is December 31, 2005. Interest will be payable either
monthly, quarterly or semi-annually, at the option of NTLIH, at LIBOR plus, at
a maximum, 2.25% per annum. The commitment fee is .375% per annum on the
unutilized portion of the (Pounds)350 million facility and is payable
quarterly in arrears. The facility is secured by first fixed and floating
charges over all present and future assets and undertakings of the United
Kingdom group. The facility contains customary financial covenants, and
certain restrictions relating to, among other things: (i) incurrence of
additional indebtedness or guarantees, (ii) investments, acquisitions and
mergers and (iii) dividend and other payment restrictions. In the absence of a
default, the New Credit Facility generally permits payments to the Company to
pay the interest and principal on existing indebtedness of the Company.
 
  In connection with the New Credit Facility, NTL (UK) Group, Inc. entered
into a European Currency Option with a bank in which NTL (UK) Group, Inc. may
purchase U.S. dollars at a fixed rate of (Pounds)1 to $1.40. The option is
exercisable on specified dates commencing through June 2001 for specified
amounts of U.S. dollars. The dates and U.S. dollar amounts correspond to the
Company's interest payment dates and amounts for its U.S. dollar denominated
debt and anticipated amounts of parent company expenses.
 
THE 7% CONVERTIBLE NOTES
 
  In June 1996, the Company issued and sold an aggregate principal amount of
$275,000,000 of its 7% Convertible Subordinated Notes Due 2008 in transactions
exempt from, or not subject to, the registration requirements of the
Securities Act. Cash interest on the 7% Convertible Notes is payable
semiannually on June 15 and December 15 of each year, commencing December 16,
1996. The 7% Convertible Notes mature on June 15, 2008. The 7% Convertible
Notes are convertible at the option of the holder thereof at any time prior to
maturity, unless previously redeemed, into shares of Common Stock of the
Company, at a conversion price of $37.875 per share subject to further
adjustment in certain events. The 7% Convertible Notes are redeemable, in
whole or in part, at the option of the Company, at any time on or after June
15, 1999, at the redemption prices set forth in the indenture pursuant to
which the 7% Convertible Notes were issued (the "7% Convertible Notes
Indenture"). Upon a Change of Control (as defined in the 7% Convertible Notes
Indenture) holders of the 7% Convertible Notes have the right to require the
Company to purchase all or any part of the 7% Convertible Notes at a purchase
price equal to 101% of the principal amount thereof and any accrued and unpaid
interest to the date of purchase. The 7% Convertible Notes Indenture contains
certain restrictions with respect to, among other things, certain Asset Sales,
payment of Additional Amounts and mergers and consolidations.
 
  The 7% Convertible Notes are unsecured obligations of the Company,
subordinated in right of payment to all exiting and future Senior Debt of the
Company (as defined in the 7% Convertible Notes Indenture) including, without
limitations, the 10 7/8% Notes, the 12 3/4% Notes and the 11 1/2% Notes.
 
  On September 13, 1996, the Commission declared effective the Company's shelf
registration statement relating to the resale of the 7% Convertible Notes and
the Common Stock issuable upon conversion thereof by the holders thereof.

                   CERTAIN 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 (the "Code") 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. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS
REGARDING THE TAX CONSEQUENCES THAT MAY BE SPECIFIC TO THEM 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 (i) a citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized under the laws of the United States or any political
subdivision thereof or therein, (iii) an estate or trust described in Section
7701(a)(30) of the Code, or (iv) a person whose worldwide income or gain is
otherwise subject to U.S. federal income taxation on a net income basis (a
"U.S. Holder"). 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 the Company, 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 Sterling Senior Notes, which
are not included in original issue discount, as discussed below, 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).
 
  Original Issue Discount. Because the Old USD Deferred Coupon Notes and the
Old Sterling Deferred Coupon Notes (the "Old Discount Notes") were issued with
original issue discount ("OID"), the New Notes issued in exchange for the Old
Discount Notes ("New Discount Notes") will also bear OID that each U.S. Holder
of a New Discount Note generally will be required to include in income as it
accrues on a yield-to-maturity basis over the term of the New Discount 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 New Discount Note will equal the excess of the stated redemption
price at maturity of such New Discount Note over its issue price. The stated
redemption price at maturity will include all payments required to be made on
the New Discount Note, whether denominated as principal or interest (other
than payments subject to remote or incidental contingencies). The issue price
of the New Discount Notes equals the issue price of the Old Discount Notes,
which was $617.24 per $1,000 principal amount at maturity in the case of the
Old USD Deferred Coupon Notes and (Pounds)586.20 per (Pounds)1,000 principal
amount at maturity in the case of the Old Sterling Deferred Coupon Notes.
 
  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
 
                                      79
<PAGE>
 
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 New Discount 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 New
Discount Notes determined as described above, generally increased by all prior
accruals of OID with respect to the particular Old Discount Notes and New
Discount Notes and decreased by the amount of payments made on such New
Discount Notes) and the New Discount Notes' yield-to-maturity (the discount
rate, which, when applied to all payments under the particular New Discount
Notes and Old Discount Notes, results in a present value equal to the issue
price of such New Discount 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 Discount 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.
 
  The Company will furnish annually to the Internal Revenue Service (the
"IRS") 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 Discount Notes were held by the U.S. Holders.
 
  Under certain circumstances described above, the Company will be required to
pay special interest on the Discount 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, however, that the IRS
may take a different position, in which case the timing and the amount of
income on the Discount 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, 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 (except to the extent of
any exchange gain or loss with respect to foreign currency, as discussed
below).
 
  In the case of a U.S. Holder who is an individual, such capital gain will be
subject to tax at a maximum 28% rate if the holding period for the New Note
(which includes the holding period of the Old Note) is more than 12 months but
not more than 18 months at the time of the sale, exchange, retirement or other
disposition, and a maximum 20% rate if such holding period is more than 18
months at such time.
 
NOTES DENOMINATED IN POUNDS STERLING
 
  The Sterling Senior Notes and the Sterling Deferred Coupon Notes (the
"Sterling Notes") are denominated in a currency unit other than the U.S.
dollar. The following is a summary of certain of the United States federal
income tax consequences to U.S. Holders of the ownership of the Sterling
Notes.
 
  Payments of Interest in Foreign Currency--Cash Method. A U.S. Holder who
uses the cash method of accounting for federal income tax purposes and who
receives interest on a Sterling Note (other than attributable to OID that has
already been included in income) will be required to include in income the
U.S. dollar value of the foreign currency payment, determined on the date such
payment is received, regardless of whether the payment is in fact converted to
U.S. dollars at that time, and such U.S. dollar value will be the U.S.
Holder's tax basis in such foreign currency.
 
  Payments of Interest in Foreign Currency--Accrual Method. A U.S. Holder who
uses the accrual method of accounting for federal income tax purposes, or who
is otherwise required to accrue interest prior to receipt, will be required to
include in income the U.S. dollar value of the amount of interest income
accrued and is
 
                                      80
<PAGE>
 
otherwise required to be taken into account with respect to a Sterling Note
during an accrual period. The U.S. dollar value of such accrued income will be
determined by translating such income at the average rate of exchange for the
accrual period, or with respect to an accrual period that spans two taxable
years, at the average rate for the partial period within the taxable year. A
U.S. Holder may elect, however, to translate such accrued interest income
using the rate of exchange on the last day of the accrual period or, with
respect to an accrual period that spans two taxable years, using the rate of
exchange on the last day of the taxable year. If the last day of an accrual
period is within five business days of the receipt of the accrued interest, a
U.S. Holder may translate such interest using the rate of exchange on the date
of receipt. The above election will apply to other debt obligations held by
the U.S. Holder and may not be changed without the consent of the IRS. Whether
or not such election is made, a U.S. Holder may recognize exchange gain or
loss (which will be treated as ordinary income or loss, but not interest
income or expense) with respect to accrued interest income on the date such
income is received. The amount of ordinary income or loss recognized will
equal the difference, if any, between the U.S. dollar value of the foreign
currency payment received (determined on the date such payment is received) in
respect of such accrual period and the U.S. dollar value of interest income
that has accrued during such accrual period (as determined above).
 
  Disposition of New Notes. As discussed above, upon the sale, exchange or
retirement of a New Note, a U.S. Holder will recognize taxable gain or loss
equal to the difference between the amount realized on the sale, exchange or
retirement and such holder's adjusted tax basis in the New Note. Such gain or
loss generally will be capital gain or loss (except to the extent of any
amounts attributable to accrued but unpaid interest) and the gain or loss will
be capital gain or loss subject to tax at a 28% maximum rate if the holder is
an individual whose holding period in such New Note (which includes such
holder's holding period in the Old Note) exceeds 12 months but does not exceed
18 months at the time of the sale, exchange, retirement or other disposition,
and will be subject to tax at a 20% maximum rate if the holder is an
individual whose holding period in such Note exceeds 18 months. To the extent
the amount realized represents accrued but unpaid interest, however, such
amounts must be taken into account as interest income, with exchange gain or
loss computed as described in "Payments of Interest in Foreign Currency"
above. If a U.S. Holder receives foreign currency on such a sale, exchange or
retirement, the amount realized will be based on the U.S. dollar value of the
foreign currency on the date of disposition (assuming the New Notes are not
publicly traded). A U.S. Holder's adjusted tax basis in a New Note will equal
the U.S. dollar cost of the Old Note (determined on the date of purchase) to
such holder, increased by the U.S. dollar value of the amounts of any OID
previously included in income by the holder and reduced by the U.S. dollar
value of any payments received by the holder (other than payments representing
ordinary interest income). In the case of an adjustment resulting from the
accrual of OID, such adjustment will be made at the rate at which such OID is
translated into U.S. dollars under the rules described below. If a U.S. Holder
purchased an Old Note with previously owned foreign currency, the holder will
recognize ordinary income or loss in an amount equal to the difference, if
any, between such holder's tax basis in the foreign currency and the U.S.
dollar fair market value of the foreign currency used to purchase such Note,
determined on the date of purchase.
 
  For purposes of the foregoing, there is a special rule for purchases and
sales of publicly traded Sterling Notes by a cash basis taxpayer under which
units of foreign currency paid or received are translated into U.S. dollars at
the spot rate on the settlement date of the purchase or sale. In that case, no
exchange gain or loss will result from currency fluctuations between the trade
date and the settlement of such a purchase or sale. An accrual basis taxpayer
may elect the same treatment required of cash basis taxpayers with respect to
purchases and sales of publicly traded Sterling Notes, provided the election
is applied consistently. Such election cannot be changed without the consent
of the IRS.
 
  Gain or loss realized upon the sale, exchange or retirement of a New Note
that is attributable to fluctuations in currency rates will be ordinary income
or loss, which will not be treated as interest income or expense. Gain or loss
attributable to fluctuations in exchange rates will equal the difference
between the U.S. dollar value of the foreign currency principal amount (which
means, for this purpose, purchase price) of the Old Note, determined on the
date such payment is received or the New Note is disposed of, and the U.S.
dollar value of the foreign currency principal amount of the Old Note,
determined on the date the U.S. holder acquired the Old
 
                                      81
<PAGE>
 
Note. Such foreign currency gain or loss will be recognized only to the extent
of the total gain or loss realized by the U.S. Holder on the sale, exchange or
retirement of the New Note.
 
  Original Issue Discount. In the case of a Sterling Deferred Coupon Note, (i)
OID will be determined in units of foreign currency, (ii) such accrued
discount will be translated into U.S. dollars as described in "Payments of
Interest in Foreign Currency--Accrual Method" above and (iii) the amount of
the foreign currency gain or loss on the accrued discount will be determined
by comparing the amount of income received attributable to the discount
(either upon payment, maturity or an earlier disposition), as translated into
U.S. dollars at the rate of exchange on the date of such receipt, with the
amount of discount accrued, as translated above.
 
  Exchange of Foreign Currencies. A U.S. Holder will have a tax basis in any
foreign currency received as interest or on the sale, exchange or retirement
of a Note equal to the U.S. dollar value of such foreign currency, determined
at the time the interest is received or at the time of the sale, exchange or
retirement. Any gain or loss realized by a U.S. Holder on a sale or other
disposition of foreign currency (including its exchange for U.S. dollars or
its use to purchase Old Notes) will be ordinary income or loss.
 
  The above discussion assumes that any change to denominate New Notes
denominated in pounds sterling to New Notes denominated in a single European
currency ("Euros") pursuant to directives of the European counsel will not be
a taxable event for U.S. federal income tax purposes. Holders should be aware
that the IRS has announced that it is studying the conversion to Euros,
including whether conversion to a Euro-denominated currency is the appropriate
time to recognize any resulting gain or loss. Holders should consult their own
tax advisors regarding the tax effect, if any, of changing to Euro-denominated
New Notes from pounds sterling denominated New Notes.
 
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 (i) a direct or indirect owner of 10% or more of the total
voting power of all voting stock of the Company, (ii) a controlled foreign
corporation related to the Company through stock ownership or (iii) 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) the Company or its paying agent receives (i) 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 (ii)
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.
 
  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.
 
  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
 
                                      82
<PAGE>
 
to United States withholding tax so long as the holder provides the Company or
its paying agent with a properly executed Form 4224. In addition, if the
Company 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 the
Company's taxable year preceding the interest payment (or such period as may
be applicable) is "active foreign business income," 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 the Company 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 (i) such gain is effectively
connected with the conduct by such Non-U.S. Holder of a trade or business
within the United States, (ii) 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 (iii) the Non-U.S.
Holder is subject to tax pursuant to the provisions of U.S. tax law applicable
to certain U.S. expatriates.
 
  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 (i) the individual does not actually or
constructively own 10% or more of the total voting power of all voting stock
of the Company and (ii) 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 the Company 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 (i) a
"controlled foreign corporation" for U.S. federal income tax purposes or (ii)
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
 
                                      83
<PAGE>
 
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 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
 
  Each broker-dealer who holds Old Notes for its own account as a result of
market-making activities or other trading activities and who receives New
Notes in exchange for Old Notes pursuant to the Exchange Offer may be a
statutory underwriter and must acknowledge that it 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. The Company acknowledges and each holder, other than a
broker-dealer, must acknowledge that it is not engaged in, does not intend to
engage in, and has no arrangement or understanding with any person to
participate in a distribution of New Notes. The Company has agreed that
starting on the Expiration Date and ending on the close of business on the
180th day following the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale.
 
  The Company 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 such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such
resale 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 state 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, the Company 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.
 
  The Company has 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 certain
liabilities, including liabilities under the Securities Act.

                         BOOK-ENTRY; DELIVERY AND FORM
 
THE EXCHANGE
 
  New Notes exchanged for Old Notes through the Book-Entry Transfer Facility
may be represented by one or more Global Notes (the "Global New Notes"). The
Global New Notes will be deposited on the date of the closing of the Exchange
Offer (the "Closing Date") 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 being referred to herein as the "Global Security
Holder").
 
  New Notes exchanged for Old Notes which are in the form of registered
definitive certificates (the "Certificated Notes") will be issued in the form
of Certificated Notes. Such Certificated Notes may, unless the Global New
Notes has 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 the Company 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 the Company that pursuant to procedures established by
it, (i) 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 (ii) 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
 
                                      86
<PAGE>
 
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 (the
"Paying Agent") 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. DTC will distribute payments
to its Participants only in U.S. dollars unless a holder of a beneficial
interest in a New Global Sterling Senior Note or a New Global Sterling
Deferred Coupon Note elects to receive payments in pounds sterling in
accordance with the procedures discussed below. Under the terms of the
Indentures, the Company 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 the
Company, the Trustee, any Transfer Agent or any agent of the Company, the
Trustee, any Transfer Agent has or will have any responsibility or liability
for (i) 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 (ii) any other matter relating to the actions and
practices of DTC or any of the Participants or the Indirect Participants.
 
  In addition to acting in its capacity as Payment Agent, the Paying Agent may
act as a foreign exchange dealer for purposes of converting British pounds
sterling to U.S. dollars for distribution through DTC, as described in the
paragraph below. When acting as a foreign exchange dealer, the Paying Agent
will derive profits from such activities in addition to the fees earned by it
for its services as Paying Agent. Each such conversion will be made on such
terms, conditions, and charges not inconsistent with the terms of the New
Notes as the Paying Agent may from time to time establish in accordance with
its regular foreign exchange practices, and subject to applicable U.S. law and
regulations.
 
  Holders of beneficial interests in the New Global Sterling Senior Notes or
New Global Sterling Deferred Coupon Notes may elect to receive payment of
principal and interest in pounds sterling or U.S. dollars, respectively, by
causing DTC through the relevant DTC Participant to notify the Paying Agent by
the time specified below of: (i) such holder's election to receive all or a
portion of such payment in pounds sterling or in U.S. dollars, respective, and
(ii) wire transfer instructions to a pounds sterling account or U.S. dollars
account, respectively. Such election in respect of any payment must be made by
the holder at the time and in the manner required by the DTC procedures
applicable from time to time and shall, in accordance with such procedures, be
irrevocable and shall relate only to such payment. DTC notifications of such
election, wire transfer instructions and the amount payable in pounds sterling
or in U.S. dollars, respectively, must be received by the Paying Agent prior
to 5:00 p.m. New York time on the fifth New York Business Day following the
relevant Record Date in the case of interest, and prior to 5:00 p.m. New York
time on the tenth day prior to the payment date for the payment of principal.
Any payments in pounds sterling or in U.S. dollars, respectively, shall be
made by wire
 
                                      87
<PAGE>
 
transfer of same-day funds to the appropriate account designated by DTC. The
term "New York Business Day" shall mean any day other than a Saturday or
Sunday or a day on which banking institutions in New York City are authorized
or required by law or executive order to close.
 
  The Company has been informed by Euroclear and CEDEL that, prior to each
payment date, Euroclear and CEDEL, acting on behalf of their participants,
will elect to receive payments of principal and interest in respect of the
beneficial interests in the Global New Notes representing New Sterling Senior
Notes or New Sterling Deferred Coupon Notes held by them in pounds sterling,
and principal and interest in respect of the beneficial interests in the
Global New Notes representing New USD Deferred Coupon Notes held by them in
U.S. dollars. In the event Euroclear and CEDEL become unwilling or unable to
make such an election on behalf of their Participants, each individual holder
of a beneficial interest in the Global Notes will be required to make its own
currency election (in accordance with the procedures set forth above) in order
to avoid payment in U.S. dollars.
 
  DTC has advised the Company 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 the Company. None of the Company, 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 the Company, 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. Investors in the Global New Notes related to any
of the Sterling Notes will be able to effect trades through DTC's Same-Day
Funds Settlement System only if payment for such trades is made in U.S.
dollars. Settlements in the New Sterling Notes in pounds sterling may be
arranged by the participants in any such transactions outside the facilities
of DTC.
 
  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 will be received
with value on the settlement date
 
                                      88
<PAGE>
 
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 the Company 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 the Company
believes to be reliable, but the Company takes 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 the Company, the
Registrar, the Transfer Agent or the Trustee nor any agent of the Company, 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 (i) DTC (x) notifies the Company that it is unwilling or
unable to continue as depository for the Global New Note and the Company
thereupon fails to appoint a successor depository within 90 days or (y) has
ceased to be a clearing agency registered under the Exchange Act, (ii) the
Company, at its option, notifies the Trustee in writing that it elects to
cause the issuance of the New Notes in certificated form or (iii) 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 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), the Company shall issue and the Trustee
shall authenticate a replacement New Note if the Trustee's and the Company's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be sufficient in the judgment of both to protect the Company, the
Trustee, any Agent or any authenticating agent from any loss which any of them
may suffer if a New Note is replaced. The Company may charge for its 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 the Company
pursuant to the provisions of the Indenture, the Company 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 by
Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York, special counsel
for the Company.

                      ENFORCEABILITY OF CIVIL LIABILITIES
 
  A substantial majority of the assets of the Company are located outside the
United States. As a result, it may not be possible for holders of the Notes 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 (i) the United States
court had jurisdiction over the original proceeding, (ii) the judgment is
final and conclusive on the merits, (iii) the judgment does not contravene
English public policy, (iv) 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 (v) 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 Holders of
Notes 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.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
NTL Incorporated
 
  We have audited the consolidated balance sheets of NTL Incorporated and
Subsidiaries as of December 31, 1997 and 1996, and the related consolidated
statements of operations, shareholders' equity (deficiency) and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of NTL Incorporated and Subsidiaries at December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with
generally accepted accounting principles.

                       NTL INCORPORATED AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION
 
  NTL Incorporated (the "Company"), through its subsidiaries and joint
ventures, owns and operates television and radio broadcasting, cable
television, telephone and telecommunications systems in the United Kingdom and
provides long-distance telephone service in the United States. Based on
revenues and identifiable assets, the Company's predominant lines of business
are television and radio broadcasting, cable television, telephone and
telecommunications services in the United Kingdom.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of the Company,
its wholly-owned subsidiaries and entities where the Company's interest is
greater than 50%. Significant intercompany accounts and transactions have been
eliminated in consolidation.
 
 Foreign Currency Translation
 
  The financial statements of the Company's foreign subsidiaries have been
translated into U.S. dollars in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 52, "Foreign Currency Translation." All
balance sheet accounts have been translated using the current exchange rates
at the respective balance sheet dates. Statement of operations amounts have
been translated using the average exchange rates for the respective years. The
gains or losses resulting from the change in exchange rates have been reported
separately as a component of shareholders' equity (deficiency).
 
 Cash Equivalents
 
  Cash equivalents are short-term highly liquid investments purchased with a
maturity of three months or less. Cash equivalents were $55,894,000 and
$339,249,000 at December 31, 1997 and 1996, respectively, which consisted
primarily of repurchase agreements and corporate commercial paper. At December
31, 1997 and 1996, none and $238,862,000, respectively, of such cash
equivalents were denominated in British pounds sterling.
 
 Marketable Securities
 
  Marketable securities are classified as available-for-sale, which are
carried at fair value. Unrealized holding gains and losses on securities, net
of tax, are carried as a separate component of shareholders' equity
(deficiency). The amortized cost of debt securities is adjusted for
amortization of premiums and accretion of discounts to maturity. Such
amortization is included in interest income. Realized gains and losses and
declines in value judged to be other than temporary will be included in
interest income. The cost of securities sold or matured is based on the
specific identification method. Interest on securities is included in interest
income.
 
  Marketable securities at December 31, 1997 consist of federal agency notes.
During the year ended December 31, 1997, there were no realized gains or
losses on sales of securities. All of the marketable securities as of December
31, 1997 had a contractual maturity of less than one year.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Fixed Assets
 
  Fixed assets are stated at cost, which includes amounts capitalized for
labor and overhead expended in connection with the design and installation of
operating equipment. Depreciation is computed by the straight-line method over
the estimated useful lives of the assets. Estimated useful lives are as
follows: operating equipment--5 to 40 years and other equipment--3 to 22.5
years.
 
  Long-lived assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable. If the
sum of the expected future undiscounted cash flows is less than the carrying
amount of the asset, a loss is recognized for the difference between the fair
value and the carrying value of the asset.
 
 Intangible Assets
 
  Intangible assets include goodwill and license acquisition costs. Goodwill
is the excess of the purchase price over the fair value of net assets acquired
in business combinations accounted for as purchases. Goodwill is amortized on
a straight-line basis over the periods benefited, principally 30 years.
License acquisition costs represent the portion of purchase price allocated to
the cable television and telecommunications licenses acquired in business
combinations. License acquisition costs are amortized on a straight-line basis
over the remaining life of the license as follows: cable television license--7
to 12 years and telecommunications license--23 years. The Company continually
reviews the recoverability of the carrying value of these assets using the
same methodology that it uses for the evaluation of its other long-lived
assets.
 
 Other Assets
 
  Other assets consist primarily of noncompetition agreements obtained in
exchange for the issuance of warrants to purchase an aggregate of 899,000
shares of common stock and deferred financing costs. The noncompetition
agreements were valued at the difference between the fair market value of the
common stock on the date of grant and the exercise price of the warrants. The
noncompetition agreements are being expensed on a straight-line basis over the
noncompetition period of primarily five years. Deferred financing costs were
incurred in connection with the issuance of debt and are amortized over the
term of the related debt.
 
 Capitalized Interest
 
  Interest is capitalized as a component of the cost of fixed assets
constructed. In 1997, 1996 and 1995, interest of $6,770,000, $10,294,000 and
$12,183,000, respectively, was capitalized.
 
 Revenue Recognition
 
  Revenues are recognized at the time the service is provided to the customer.
 
 Cable Television System Costs, Expenses and Revenues
 
  The Company accounts for costs, expenses and revenues applicable to the
construction and operation of its cable television, telephone and
telecommunications systems in accordance with SFAS No. 51, "Financial
Reporting by Cable Television Companies."
 
 Advertising Expense
 
  The Company expenses the cost of advertising as incurred. Advertising costs
were $31,003,000, $22,727,000 and $10,370,000 in 1997, 1996 and 1995,
respectively.

 Net (Loss) Per Share
 
  In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings Per Share". SFAS 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings
per share. Unlike primary earnings per share, basic earnings per share
excludes any dilutive effects of options, warrants and convertible securities.
Diluted earnings per share is very similar to the previously reported fully
diluted earnings per share. The Company adopted SFAS No. 128 for each of the
three years in the period ended December 31, 1997.
 
 Stock-Based Compensation
 
  The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." The Company applies APB Opinion No.
25, "Accounting for Stock Issued to Employees" and related interpretations in
accounting for its stock option plans.
 
 Reclassifications
 
  Certain prior year amounts have been reclassified to conform to the 1997
presentation.
 
3. RECENT ACCOUNTING PRONOUNCEMENTS
 
 Comprehensive Income
 
  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". SFAS No. 130 requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence
as other financial statements. SFAS No. 130 is effective for fiscal years
beginning after December 15, 1997. The Company will adopt SFAS No. 130 in the
first interim period for its fiscal year ending December 31, 1998.
 
 Segment Reporting
 
  In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information". SFAS No. 131 establishes standards for
the way that public business enterprises report information about operating
segments in annual financial statements and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. It also establishes standards for related
disclosures about products and services, geographic areas, and major
customers. SFAS No. 131 is effective for financial statements for periods
beginning after December 15, 1997. The Company will adopt SFAS No. 131 for its
fiscal year ending December 31, 1998.
 
4. CERTAIN SIGNIFICANT RISKS AND UNCERTAINTIES
 
 Need for Additional Financing
 
  The Company will require additional financing in the future. There can be no
assurance that the required financing will be obtainable on acceptable terms.
 
 Requirements to Meet Build Milestones
 
  The telecommunications license for each United Kingdom franchise contains
specific construction milestones. Based on current network construction
scheduling, the Company believes it will be able to satisfy its milestones in
the future, but there can be no assurance that such milestones will be met. If
the Company is unable

<PAGE>
 
                       NTL INCORPORATED AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
to meet the construction milestones required by any of its licenses and is
unable to obtain modifications to the milestones, the relevant licenses could
be revoked.
 
 Concentrations
 
  The Company's television and radio broadcasting business is substantially
dependent upon contracts with a small group of companies for the right to
broadcast their programming, and upon a site sharing agreement for a large
number of its transmission sites. The loss of any one of these contracts or
the site sharing agreement could have a material adverse effect on the
business of the Company.
 
 Limited Access to Programming
 
  The Company's ability to make a competitive offering of cable television
services is dependent on the Company's ability to obtain access to programming
at a reasonable cost. There can be no assurance that the Company's current
programming will continue to be available on acceptable commercial terms or at
all.
 
 Currency Risk
 
  To the extent that the Company obtains financing in United States dollars
and incurs construction and operating costs in British pounds sterling, it
will encounter currency exchange rate risks. In addition, the Company's
revenues are generated primarily in British pounds sterling while its interest
and principal obligations with respect to most of the Company's existing
indebtedness are payable in United States dollars. The Company has entered
into an option agreement to hedge some of the risk of exchange rate
fluctuations related to interest payments on United States dollar denominated
debt.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In October 1996, the Company acquired the remaining 40% interest it did not
already own in CableTel Newport in exchange for 780 shares of the Company's
Series A Preferred Stock. CableTel Newport owns and operates cable television,
telephone and telecommunications franchises in South Wales. The Series A
Preferred Stock was valued at $49,000,000, based on an appraisal as of the
date of issuance. The fair value of the net tangible assets acquired of
$67,710,000 exceeded the aggregate purchase price of $49,062,000 (including
costs incurred of $62,000) by $18,648,000, which is classified as a reduction
to license acquisition costs.
 
  In September 1996, the Company acquired the remaining 30% minority interest
of English Cable Enterprises, Inc. ("ECE") that the Company did not own, in
exchange for 1,415,000 shares of its common stock. ECE, through its
subsidiaries, owns four cable television, telephone and telecommunications
licenses in the northern suburbs of London. The value of the shares, based on
the market price on the date of issuance, of $34,137,000 plus costs incurred
of $204,000 exceeded the fair value of the net tangible assets acquired by
$28,649,000, which is classified as license acquisition costs.
 
  In May 1996, an indirect wholly-owned subsidiary of the Company, NTL
Investment Holdings Limited ("NTLIH"), acquired NTL Group Limited for payments
of approximately (Pounds)204,000,000 at closing, (Pounds)17,100,000 in October
1996 and (Pounds)35,000,000 in May 1997. NTL Group Limited provides television
and radio transmission services and a range of other services in the
broadcasting and telecommunications industries. This acquisition has been
accounted for as a purchase, and, accordingly, the net assets and results of
operations of NTL Group Limited have been included in the consolidated

    no less than (Pounds)480,000,000 or such greater amount as is necessary to
    ensure that the Company's United Kingdom operations remain fully funded by
    reference to an agreed business plan. The facility will be used to finance
    capital expenditures and working capital for the Company's United Kingdom
    operations, including its local broadband, national telecommunications and
    national digital television networks. A portion of the facility
    ((Pounds)75,000,000) is conditional upon the execution of contracts to
    provide digital television transmission services to certain third parties.
    Chase has provided a portion of the (Pounds)555,000,000 facility in the form
    of a (Pounds)350,000,000 facility to the Company on the same terms as to
    restrictions, covenants, guarantees and security as the (Pounds)555,000,000

    on December 31, 2005. Interest is payable either monthly, quarterly or semi-
    annually, at the option of NTLIH, at LIBOR plus, at a maximum, 2.25% per
    annum. The commitment fee is .375% per annum on the unutilized portion of
    the (Pounds)350,000,000 facility and is payable quarterly in arrears. The
    facility is secured by first fixed and floating charges over all present and
    future assets and undertakings of the United Kingdom group. The facility
    contains customary financial covenants, and certain restrictions relating
    to, among other things: (i) incurrence of additional indebtedness or
    guarantees, (ii) investments, acquisitions and mergers and (iii) dividend
    and other payment restrictions. In the absence of a default, the facility
    generally permits payments to the Company to pay interest and principal of
    existing indebtedness of the Company. At December 31, 1997, restricted net
    assets were approximately $1,861,000,000.

12. FAIR VALUES OF FINANCIAL INSTRUMENTS
 
  The following methods and assumptions were used by the Company in estimating
its fair value disclosures for financial instruments:
 
  Cash and cash equivalents: The carrying amounts reported in the consolidated
balance sheets approximate fair value.
 
  Long-term debt: The fair values of the 10 7/8% Notes, the 12 3/4% Notes, the
11 1/2% Notes, the 10% Notes, the 7 1/4% Convertible Notes and the 7%
Convertible Notes are based on the quoted market price. The fair value of the
Term Loan and Revolving Facility is estimated using discounted cash flow
analysis, based on the Company's incremental borrowing rate for similar types
of borrowing arrangements.
 
  Redeemable Preferred Stock: The fair value is based on the quoted market
price.
 
  The carrying amounts and fair values of the Company's financial instruments
are as follows:

13. RELATED PARTY TRANSACTIONS
 
  On July 25, 1990, Cellular Communications, Inc. ("CCI") and AirTouch
Communications, Inc. ("AirTouch") entered into a Merger and Joint Venture
Agreement, as amended as of December 14, 1990. In connection with this
agreement, on July 31, 1991, CCI distributed to its shareholders the stock of
the Company.
 
  Through August 1996, CCI provided management, financial and legal services
to the Company. Amounts charged to the Company included direct costs where
identifiable, and indirect costs allocated utilizing direct labor hours as
reported by the common officers and employees of CCI and the Company. For the
years ended December 31, 1996 and 1995, CCI charged $1,194,000, and
$1,644,000, respectively, which is included in corporate expenses. In August
1996, upon the merger of CCI with AirTouch, the Company commenced providing
management, financial, legal and technical services to Cellular Communications
International, Inc. ("CCII") and CoreComm Incorporated ("CoreComm"). In 1996,
the Company charged CCII and CoreComm $351,000 and $200,000, respectively,
which included direct costs where identifiable and allocated corporate
overhead based upon the amount of time incurred on CCII and CoreComm business
by the common officers and employees of the Company, CCII and CoreComm. These
charges reduced corporate expenses in 1996.
 
  In January 1997, the Company, CoreComm and CCII agreed to a change in the
Company's fee for the provision of services. In 1997, the Company charged
CoreComm and CCII $1,492,000 and $871,000, respectively, for direct costs

15. SHAREHOLDERS' EQUITY (DEFICIENCY)
 
 Stock Split
 
  On July 25, 1995, the Company declared a 4-for-3 stock split by way of stock
dividend, which was paid on August 11, 1995. All common stock data in the
Consolidated Financial Statements give effect to the stock split.
 
 Series Preferred Stock
 
  In October 1996, the Board of Directors created and authorized for issuance
2,000 shares of 5% Non-Voting Convertible Preferred Stock, Series A ("Series A
Preferred Stock"), of which 780 shares were issued in
 
                                     F-20

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
connection with the CableTel Newport acquisition. Each share of Series A
Preferred Stock has a stated value of $100,000, subject to certain exceptions.
The holders of Series A Preferred Stock are entitled to receive cumulative
dividends beginning in October 2001 at the rate of 5% of the stated value,
payable semi-annually in arrears, subject to certain exceptions. Dividends may
be paid, in the sole discretion of the Board of Directors, in cash, in common
stock or in additional shares of Series A Preferred Stock. The Company has the
right, exercisable at any time, to redeem all or some of the Series A
Preferred Stock at a price equal to the aggregate stated value of the shares
to be redeemed, together with all accrued and unpaid dividends, in cash or in
shares of common stock (based on the average market price of the common stock,
as defined). The holder of Series A Preferred Stock has the right to convert
shares of Series A Preferred Stock into common stock equal to the aggregate
stated value of Series A Preferred Stock divided by the greater of (a) $40.00
or (b) the average market price of the common stock, as defined. The Series A
Preferred Stock has a liquidation preference equal to the stated value per
share plus accrued and unpaid dividends.
 
 Warrants
 
  In 1993, the Company issued warrants to purchase an aggregate of
approximately 899,000 shares of common stock at an initial exercise price of
$8.35 per share in connection with certain noncompetition agreements. The
exercise price decreased to $6.96 per share in the second year after the grant
and to $5.57 per share thereafter. The warrants were valued at $13,193,000,
the difference between the fair market value of the common stock on the date
of grant and $5.57 per share. The warrants expire in 2000.
 
  In 1996, pursuant to the terms of the consent solicitations to the holders
of the 10 7/8% Notes and to the holders of the 12 3/4% Notes to gain consent
to modify certain indenture provisions, the Company paid an aggregate of
$3,592,000 in consent payments and issued warrants to purchase 164,000 shares
of common stock at an exercise price of $23.78 per share in lieu of additional
consent payments of $1,641,000. The warrants expire in 2006.
 
 Shareholder Rights Plan
 
  The Rights Agreement provides that one Right will be issued with each share
of common stock issued on or after October 13, 1993. The Rights are
exercisable upon the occurrence of certain potential takeover events and will
expire in October 2003 unless previously redeemed by the Company. When
exercisable, each Right entitles the owner to purchase from the Company one
one-hundredth of a share of Series A Junior Participating Preferred Stock
("Rights Preferred Stock") at a purchase price of $100.
 
  The Rights Preferred Stock will be entitled to a minimum preferential
quarterly dividend payment of $.01 per share and will be entitled to an
aggregate dividend of 100 times the dividend, if any, declared per share of
common stock. In the event of liquidation, the holders of Rights Preferred
Stock will be entitled to a minimum preferential liquidation payment of $1 per
share and will be entitled to an aggregate payment of 100 times the payment
made per share of common stock. Each share of Rights Preferred Stock will have
100 votes and will vote together with the common stock. In the event of any
merger, consolidation or other transaction in which shares of common stock are
changed or exchanged, each share of Rights Preferred Stock will be entitled to
receive 100 times the amount received per share of common stock. These rights
are protected by customary antidilution provisions.

 Stock Options
 
  There are 2,164,000 shares of common stock reserved for issuance under the
OCOM Corporation (a wholly-owned subsidiary of the Company) 1991 Stock Option
Plan. The plan provides that incentive stock options ("ISOs") be granted at
the fair market value of OCOM's common stock on the date of grant, and
nonqualified stock options ("NQSOs") be granted at not less than 85% of the
fair market value of OCOM's common stock on the date of grant. Options are
exercisable as to 20% of the shares subject thereto on the date of grant and
become exercisable as to an additional 20% of the shares subject thereto on
each January 1 thereafter, while the optionee remains an employee of the
Company. Options will expire ten years after the date of the grant.
 
  There are 6,653,000 shares of common stock reserved for issuance under the
NTL Incorporated 1993 Stock Option Plan. The exercise price of an ISO may not
be less than 100% of the fair market value of the Company's common stock on
the date of grant, and the exercise price of a NQSO may not be less than 85%
of the fair market value of the Company's common stock on the date of grant.
Options are exercisable as to 20% of the shares subject thereto on the date of
grant and become exercisable as to an additional 20% of the shares subject
thereto on each January 1 thereafter, while the optionee remains an employee
of the Company. Options will expire ten years after the date of the grant.
 
  There are 100,000 shares of common stock reserved for issuance under the
OCOM Corporation Non-Employee Director Stock Option Plan. The plan provides
that all options be granted at the fair market value of OCOM's common stock on
the date of grant, and options will expire ten years after the date of the
grant. Options are exercisable as to 20% of the shares subject thereto on the
date of grant and become exercisable as to an additional 20% of the shares
subject thereto on each subsequent anniversary of the grant date, while the
optionee remains a director of the Company. Options will expire ten years
after the date of the grant.
 
  There are 320,000 shares of common stock reserved for issuance under the NTL
Incorporated 1993 Non-Employee Director Stock Option Plan. Under the terms of
this plan, options will be granted to members of the Board of Directors who
are not employees of the Company or any of its affiliates. The plan provides
that all options be granted at the fair market value of the Company's common
stock on the date of grant, and options will expire ten years after the date
of the grant. Options are exercisable as to 20% of the shares subject thereto
on the date of grant and become exercisable as to an additional 20% of the
shares subject thereto on each subsequent anniversary of the grant date while
the optionee remains a director of the Company. Options will expire ten years
after the date of the grant.
 
  Pro forma information regarding net loss and net loss per share is required
by SFAS No. 123, and has been determined as if the Company had accounted for
its employee stock options under the fair value method of that Statement. The
fair value for these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions for 1997, 1996 and 1995: risk-free interest rates of 5.89%, 6.56%
and 6.61%, respectively, dividend yield of 0%, volatility factor of the
expected market price of the Company's common stock of .276, .255 and .255,
respectively, and a weighted-average expected life of the option of 10 years.
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's stock options have characteristics significantly
different from those of traded options and because changes in the subjective
input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of its stock options.

calculated using the attained age method. The Company's policy is to fund
amounts to the defined benefit plan necessary to comply with the funding
requirements as prescribed by the laws and regulations in the United Kingdom.
The change in the projected benefit obligation in 1997 is due to the change in
actuarial assumptions used.

18. COMMITMENTS AND CONTINGENT LIABILITIES
 
  As of December 31, 1997, the Company was committed to pay approximately
$78,000,000 for equipment and services.
 
  The Company has licenses issued by the United Kingdom Department of Trade
and Industry ("DTI") and the United Kingdom Independent Television Commission
("ITC") for its cable television, telephone and telecommunications business.
The initial terms of the Company's licenses was 23 years for the DTI licenses
and 15 years for the ITC licenses. The Company's licenses expire in 2008 to
2016 for the DTI licenses and 1999 to 2005 for the ITC licenses. The DTI
requires a fixed annual renewal fee of (Pounds)2,500 ($4,200) per license. The
ITC requires an annual license fee ranging from (Pounds)1,300 ($2,200) to
(Pounds)7,900 ($13,100) per license based on the number of homes in the
licensed area, which is subject to adjustment annually. The Company's license
fees in 1997 were $316,000.
 
  In addition, the Company was awarded certain newly issued licenses by the
ITC in 1995. Pursuant to the terms of the local delivery license ("LDL") for
Northern Ireland granted to a wholly-owned subsidiary of the Company, the
Company is required to make annual cash payments to the ITC for fifteen years
commencing in January 1997 in the amount of approximately (Pounds)14,400,000
($23,800,000) (subject to adjustments for inflation). Such payments are in
addition to the percentages of qualifying revenue already set by the ITC of 0%
for the first ten years and 2% for the last five years of the fifteen year
license. The Company paid $23,587,000 in 1997.
 
  Pursuant to the terms of the LDL for Glamorgan and Gwent, Wales granted to a
wholly-owned subsidiary of the Company, the Company is required to make annual
cash payments to the ITC for fifteen years, commencing in the first full
calendar year after the start of operations, in the amount of (Pounds)104,188
($172,000). Such payments are in addition to the percentages of qualifying
revenue already set by the ITC of 0% for the first five years, 2% for the
second five years and 4% for the last five years of the fifteen-year license.
 
  A significant portion of NTL Group Limited's revenues is attributable to the
provision of television and radio transmission and distribution services and
the provision of telecommunications services. In the United Kingdom, the
provision of such services is governed by the Telecommunications Act and The
Wireless Telegraphy Act 1949. NTL Group Limited holds five licenses under the
Telecommunications Act. The initial terms of these licenses were 10 or 25
years. These licenses expire in 2002 to 2021. NTL Group Limited holds a number
of Wireless Telegraphy Act licenses which continue in force primarily from
year to year unless revoked or unless any of the license fees are not paid.
The Company paid $3,447,000 in 1997 in connection with these licenses.

share falls below $10.00, Partners has the right to terminate the transaction,
subject to the Company's right to adjust the exchange ratio such that
Partners' shareholders would receive $10.00 for each Partners share. Under
certain circumstances, the consideration payable to Partners' shareholders may
be adjusted based on the proceeds of the potential exercise of certain rights
of first refusal with respect to Partners' interests in the London and
Birmingham franchises. Completion of the transaction is subject to a number of
closing conditions including regulatory approvals, shareholder approvals and
consents from the holders of the Company's and Partners' debt.

senior unsecured indebtedness of the Company and rank senior in right of
payment to all subordinated indebtedness of the Company.

at any time on or after April 1, 2003, at a redemption price of 104 3/4% to
105 3/8% that declines annually to 100% in 2006, in each case together with

among other things: (i) incurrence of additional indebtedness and the issuance
of preferred stock, (ii) dividend and other payment restrictions and (iii)

NOTE I--COMMITMENTS AND CONTINGENT LIABILITIES
 
  As of March 31, 1998, the Company was committed to pay approximately
$103,300,000 for equipment and services.
 
  The Company has licenses issued by the United Kingdom Department of Trade
and Industry ("DTI") and the United Kingdom Independent Television Commission
("ITC") for its cable television ("CATV"), telephone and telecommunications
business. The initial terms of the Company's licenses was 23 years for the DTI
licenses and 15 years for the ITC licenses. The Company's licenses expire in
2008 to 2016 for the DTI licenses and 1999 to 2005 for the ITC licenses. The
DTI requires a fixed annual renewal fee of (Pounds)2,500 ($4,100) per license.
The ITC requires an annual license fee ranging from (Pounds)1,300 ($2,100) to
(Pounds)7,900 ($13,000) per license based on the number of homes in the
licensed area, which is subject to adjustment annually. The provision of the
Company's transmission and distribution services is governed by the
Telecommunications Act and the Wireless Telegraphy Act 1949. The Company holds
five licenses under the Telecommunications Act. The initial terms of these
licenses were 10 or 25 years. These licenses expire in 2002 to 2021. The
Company holds a number of Wireless Telegraphy Act licenses which continue in
force primarily from year to year unless revoked or unless any of the license
fees are not paid. The Company's license fees paid in the three months ended
March 31, 1998 were $634,000.
 
  In addition, the Company was awarded certain newly issued licenses by the
ITC in 1995. Pursuant to the terms of the local delivery license ("LDL") for
Northern Ireland granted to a wholly-owned subsidiary of the Company, the
Company is required to make annual cash payments to the ITC for fifteen years
commencing in January 1997 in the amount of approximately (Pounds)14,400,000
($24,100,000) (subject to adjustments for inflation). The fee for 1998 is
(Pounds)14,951,661. Such payments are in addition to the percentages of
qualifying revenue already set by the ITC of 0% for the first ten years and 2%
for the last five years of the fifteen year license. The Company paid
$6,152,000 in the three months ended March 31, 1998.
 
  Pursuant to the terms of the LDL for Glamorgan and Gwent, Wales granted to a
wholly-owned subsidiary of the Company, the Company is required to make annual
cash payments to the ITC for fifteen years, commencing in January 1998, in the
amount of (Pounds)104,188 ($174,000). Such payments are in addition to the
percentages of qualifying revenue already set by the ITC of 0% for the first
five years, 2% for the second five years and 4% for the last five years of the
fifteen year license. The Company paid $43,000 in the three months ended March
31, 1998.
 
  The Company is involved in, or has been involved in, certain disputes and
litigation arising in the ordinary course of its business, including claims
involving contractual disputes and claims for damages to property and personal
injury resulting from construction of the Company's networks and the
maintenance and servicing of the Company's transmission masts. None of these
matters are expected to have a material adverse effect on the Company's
financial position, results of operations or cash flows.
 
NOTE J--PARTNERS ACQUISITION
 
  In February 1998, the Company entered into an agreement and plan of
amalgamation (the "Agreement") with Comcast UK Cable Partners Limited
("Partners"). Under the Agreement, Partners' shareholders will receive 0.3745
shares of the Company's Common Stock for each share of Partners Common Stock.
Based on the closing price of the Company's Common Stock on the date of the

share falls below $10.00, Partners has the right to terminate the transaction,
subject to the Company's right to adjust the exchange ratio such that
Partners' shareholders would receive $10.00 for each Partners share. Under
certain circumstances, the consideration payable to Partners' shareholders may
be adjusted based on the proceeds of the potential exercise by a third party
of certain purchase rights with respect to Partners' interests in the London
and Birmingham franchises. Completion of the transaction is subject to a
number of closing conditions including regulatory approvals, shareholder
approvals and consents from the holders of the Company's and Partners' debt.

Board of Directors and Shareholders
Comcast UK Cable Partners Limited
 
  We have audited the accompanying consolidated balance sheet of Comcast UK
Cable Partners Limited (a company incorporated in Bermuda) and subsidiaries as
of December 31, 1997 and 1996, and the related consolidated statements of
operations, shareholders' equity and of cash flows for each of the three years
in the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Comcast UK Cable Partners
Limited and subsidiaries as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1997 in conformity with accounting principles
generally accepted in the United States of America.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
1. BUSINESS
 
  Comcast UK Cable Partners Limited and subsidiaries (the "Company"), a
Bermuda company incorporated in 1992, was formed to develop, construct, manage
and operate the interests of Comcast Corporation ("Comcast") in the United
Kingdom ("UK") cable and telecommunications industry. The Company is a
controlled subsidiary of Comcast U.K. Holdings, Inc. ("Holdings"), a Delaware
corporation indirectly wholly owned by Comcast. As of December 31, 1997, the
Company has interests in four operations (the "Operating Companies"):
Birmingham Cable Corporation Limited ("Birmingham Cable"), in which the
Company owns a 27.5% interest, Cable London PLC ("Cable London"), in which the
Company owns a 50.0% interest, Cambridge Holding Company Limited ("Cambridge
Cable"), in which the Company owns a 100% interest and two companies holding
the franchises for Darlington and Teesside, England ("Teesside"), in which the
Company owns a 100% interest. The Company also owns a 100% interest in Comcast
UK Holdings Limited ("UK Holdings"), a company incorporated in Bermuda in
December 1997.
 
  On February 4, 1998, the Company entered into a definitive agreement to
amalgamate (the "NTL Transaction") with a wholly owned Bermuda subsidiary of
NTL Incorporated ("NTL"). NTL is an alternative telecommunications company in
the UK and is listed on Nasdaq. The NTL Transaction is expected to close in
1998, subject to, among other things, the receipt of required Bermuda and UK
regulatory approvals, the approval of the Company's and NTL's shareholders,
the consent of the Company's and NTL's bondholders, the consent of certain NTL
bank lenders and other customary closing matters. Comcast, through Holdings,
is the sole holder of the multiple-voting Class B Common Shares of the Company
and has agreed to vote for the transaction, assuring its approval by the
Company's shareholders. Upon consummation of the NTL Transaction, the Company
would become a wholly owned subsidiary of NTL.
 
  Except in the circumstances described below, the Company's shareholders will
receive 0.3745 shares of NTL common stock for each of the Company's Class A
Common Shares or Class B Common Shares. If the average closing price of the
NTL common stock for a specified period of time prior to the Company's
shareholders meeting to approve the NTL Transaction (the "Average Price") is
less than $26.70, the Company will have the option to terminate the NTL
Transaction, subject to the right of NTL to adjust the exchange ratio such
that one share of the Company's Class A Common Shares or Class B Common Shares
will be exchanged for a number of shares of NTL common stock equal to $10.00
(based on the Average Price).
 
  Pursuant to existing arrangements between the Company and Telewest
Communications plc ("Telewest"), a co-owner of interests in Cable London and
Birmingham Cable, Telewest has certain rights (the "Telewest Rights") to
acquire either or both of the Company's interests in these systems as a result
of the NTL Transaction. However, as described in the following paragraphs, the
consummation of the NTL Transaction is not dependent on the resolution of the
Telewest Rights.
 
  If the Telewest Rights have been exercised prior to the closing of the NTL
Transaction, the Company's shareholders may receive (at the option of NTL), in
lieu of a portion of the consideration allocable to the interest subject to
the exercised Telewest Rights, the per share proceeds from the sale of the
interest to Telewest (net of taxes on gain on sale), payable in cash or shares
of NTL common stock valued at the greater of $30.00 per share or the Average
Price at closing (the "Exercise Consideration").
 
  Similarly, if at closing either of the Telewest Rights have not been
exercised and have not been waived or otherwise expired, the Company's
shareholders may receive (at the option of NTL), shares of a new class of NTL
preferred stock equal to a portion of the consideration allocable to the
interest subject to the unexercised Telewest Rights. Any shares of NTL
preferred stock would have the same voting and dividend rights as shares

of NTL common stock, would be subject to redemption as described below, and
would be expected to be listed for trading on Nasdaq. If following closing the
Telewest Rights are exercised, the NTL preferred stock will be redeemed for
the Exercise Consideration (based on the Average Price at the time of
exercise). If the Telewest Rights are resolved without being exercised, the
NTL preferred stock will be redeemed for NTL common stock on a one-for-one
basis.
 
  Of the consideration to be received by the Company's shareholders in the NTL
Transaction, the parties have allocated 31% to the Company's interest in Cable
London and 17% to the Company's interest in Birmingham Cable. However, if
either or both of the Telewest Rights are exercised, the actual consideration
to be received by the Company's shareholders may be materially different from
the portion of the consideration (the "allocable portion") which has been
allocated by the parties to the Company's respective interests in Cable London
and Birmingham Cable, depending on, among other things, the value of these
interests, as finally determined, whether NTL exercises its option to deliver
the Exercise Consideration in lieu of the allocable portion and, the amount of
any taxes payable by the Company on the sale of these interests.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Accounting
 
  Subsidiaries of the Company maintain their books and records in accordance
with accounting principles generally accepted in the UK. The consolidated
financial statements have been prepared in accordance with generally accepted
accounting principles as practiced in the United States ("US") and are stated
in UK pounds sterling ("UK Pound"). There were no significant differences
between accounting principles followed for UK purposes and generally accepted
accounting principles practiced in the US. The UK Pound exchange rate as of
December 31, 1997 and 1996 was US $1.65 and US $1.71, respectively.
 
 Basis of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and all wholly owned subsidiaries. All significant intercompany accounts and
transactions among the consolidated entities have been eliminated.
 
 Management's Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Values
 
  The estimated fair value amounts presented in these notes to consolidated
financial statements have been determined by the Company using available
market information and appropriate methodologies. However, considerable
judgment is required in interpreting market data to develop the estimates of
fair value. The estimates presented herein are not necessarily indicative of
the amounts that the Company could realize in a current market exchange. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts. Such fair value estimates
are based on pertinent information available to management as of December 31,
1997 and 1996, and have not been comprehensively revalued for purposes of
these consolidated financial statements since such dates. A reasonable
estimate of the amounts due to affiliates

                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
and long-term debt due to shareholder is not practicable to obtain because of
the related party nature of these items and the lack of quoted market prices.
 
 Cash Equivalents and Short-term Investments
 
  Cash equivalents consist principally of commercial paper, time deposits and
money market funds with maturities of three months or less when purchased.
Short-term investments as of December 31, 1996 consist principally of
commercial paper and corporate floating rate notes with maturities greater
than three months when purchased. The carrying amounts of the Company's cash
equivalents and short-term investments, classified as available for sale
securities, approximate their fair values.
 
 Investments in Affiliates
 
  Investments in entities in which the Company has the ability to exercise
significant influence over the operating and financial policies of the
investee are accounted for under the equity method. Equity method investments
are recorded at original cost and adjusted periodically to recognize the
Company's proportionate share of the investees' net income or losses after the
date of investment, additional contributions made and dividends received. The
differences between the Company's recorded investments and its proportionate
interests in the book value of the investees' net assets are being amortized
to equity in net losses of affiliates over the remaining original lives of the
related franchises of eight years.
 
 Prematurity Period
 
  The Company accounts for costs, expenses and revenues applicable to the
construction and operation of its cable telecommunications systems in Teesside
and Cambridge Cable under the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 51, "Financial Reporting by Cable Television
Companies."
 
  Under SFAS No. 51, during the period while the systems are partially under
construction and partially in service (the "Prematurity Period"), costs of
cable telecommunications plant, including materials, direct labor and
construction overhead are capitalized. Subscriber-related costs and general
and administrative costs are expensed as incurred. Costs incurred in
anticipation of servicing a fully operating system that will not vary
regardless of the number of subscribers are partially expensed and partially
capitalized, based upon the percentage of average actual or estimated
subscribers, whichever is greater, to the total number of subscribers expected
at the end of the Prematurity Period (the "Fraction").
 
  During the Prematurity Period, depreciation and amortization of system
assets is determined by multiplying the depreciation and amortization of the
total capitalized system assets expected at the end of the Prematurity Period
by the Fraction. At the end of the Prematurity Period, depreciation and
amortization of system assets is based on the remaining undepreciated cost at
that date.
 
  As of December 31, 1997, two of the Company's five franchise areas which are
under construction have completed their Prematurity Period. The remaining
Prematurity Periods are expected to terminate at various dates in 1998 and
1999.
 
 Property and Equipment
 
  Property and equipment, which consists principally of system assets, is
shown at historical cost less accumulated depreciation. Improvements that
extend asset lives are capitalized; other repairs and maintenance charges are
expensed as incurred. The cost and related accumulated depreciation applicable
to assets sold or

retired are removed from the accounts and the gain or loss on disposition is
recognized as a component of depreciation expense.
 
 System assets
 
  Prior to the Prematurity Period, no depreciation is provided on system
assets. During the Prematurity Period, depreciation is provided in accordance
with SFAS No. 51.
 
  Depreciation of system assets is provided by the straight-line method over
estimated useful lives as follows:

   Buildings........................................................... 40 years
   Fixtures, fittings and equipment....................................  5 years
   Vehicles............................................................  4 years
   Computers...........................................................  4 years
</TABLE>
 
 Leased Assets
 
  Assets held under capital leases are treated as if they had been purchased
outright and the corresponding liability is included in long-term debt.
Capital lease payments include principal and interest, with the interest
portion being expensed. Payments on operating leases are expensed on a
straight-line basis over the lease term.
 
 Deferred Charges
 
  Deferred charges consist primarily of franchise acquisition costs
attributable to obtaining, developing and maintaining the franchise licenses
of Teesside and Cambridge Cable, debt acquisition costs relating to the sale
of approximately $517.3 million principal amount at maturity of the Company's
11.20% Senior Discount Debentures Due 2007 (the "2007 Discount Debentures"--
see Note 7) and goodwill arising from the SingTel Transaction (see Note 4).
Franchise acquisition costs are being amortized on a straight-line basis over
the remaining original lives of the related franchises of 12 to 15 years. Debt
acquisition costs are being amortized on a straight-line basis over the term
of the 2007 Discount Debentures of 12 years. Goodwill is being amortized on a
straight-line basis over the remaining original lives of the related
franchises of 11 years.
 
 Valuation of Long-Lived Assets
 
  The Company periodically evaluates the recoverability of its long-lived
assets, including property and equipment and deferred charges, using objective
methodologies. Such methodologies include evaluations based on the cash flows
generated by the underlying assets or other determinants of fair value.

                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
 
 Revenue Recognition
 
  Service income is recognized as service is provided. Credit risk is managed
by disconnecting services to subscribers who are delinquent.
 
 Stock-Based Compensation
 
  Effective January 1, 1996, the Company adopted the provisions of SFAS No.
123, "Accounting for Stock-Based Compensation," which encourages, but does not
require, companies to record compensation cost for stock-based compensation
plans at fair value. The Company has elected to continue to account for stock-
based compensation in accordance with Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations,
as permitted by SFAS No. 123. Compensation expense for stock options is
measured as the excess, if any, of the quoted market price of the Company's
stock at the date of grant over the amount an employee must pay to acquire the
stock. Compensation expense for stock appreciation rights is recorded annually
based on changes in quoted market prices of the Company's stock or other
determinants of fair value at the end of the year (see Note 8).
 
 Income Taxes
 
  The Company is exempt from US federal, state and local income taxes. At the
present time, no income, profit, capital or capital gains taxes are levied in
Bermuda and, accordingly, no provision for such taxes has been recorded by the
Company. In the event that such taxes are levied, the Company has received an
undertaking from the Bermuda Government exempting it from all such taxes until
March 2016.
 
  The Company's wholly owned subsidiaries recognize deferred tax assets and
liabilities for temporary differences between the financial reporting basis
and the tax basis of their assets and liabilities and expected benefits of
utilizing net operating loss carryforwards. The impact on deferred taxes of
changes in tax rates and laws, if any, applied to the years during which
temporary differences are expected to be settled, are reflected in the
financial statements in the period of enactment.
 
 Derivative Financial Instruments
 
  The Company uses derivative financial instruments, principally foreign
exchange option contracts ("FX Options"), to manage its exposure to
fluctuations in foreign currency exchange rates. Written FX Options are
marked-to-market on a current basis in the Company's consolidated statement of
operations (see Note 6).
 
  Those instruments that have been entered into by the Company to hedge
exposure to foreign currency exchange rate risks are periodically examined by
the Company to ensure that the instruments are matched with underlying
liabilities, reduce the Company's risks relating to foreign currency exchange
rates, and, through market value and sensitivity analysis, maintain a high
correlation to the underlying value of the hedged item. For those instruments
that do not meet the above criteria, variations in their fair value are
marked-to-market on a current basis in the Company's consolidated statement of
operations.
 
  The Company does not hold or issue any derivative financial instruments for
trading purposes and is not a party to leveraged instruments (see Notes 6 and
7). The credit risks associated with the Company's derivative financial
instruments are controlled through the evaluation and monitoring of the
creditworthiness of the counterparties. Although the Company may be exposed to
losses in the event of nonperformance by the counterparties, the Company does
not expect such losses, if any, to be significant.

                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
 
 Net Loss Per Share
 
  In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings per Share," which was adopted by the Company effective
for the year ended December 31, 1997, as required by the statement. For the
years ended December 31, 1997, 1996 and 1995, the Company's potential common
shares have an antidilutive effect on the loss per share and, therefore, have
not been used in determining the total weighted average number of common
shares outstanding. Diluted loss per share for 1997, 1996 and 1995 is
antidilutive and, therefore, has not been presented.
 
 Reclassifications
 
  Certain reclassifications have been made to the prior years' consolidated
financial statements to conform to those classifications used in 1997.
 
3. TEESSIDE ACQUISITION
 
  In June 1994, the Company acquired all of the outstanding shares of two
companies that owned Teesside, which comprise an area containing approximately
254,000 homes. The construction of Teesside's cable telecommunications network
commenced in the third quarter of 1994. Teesside added its initial cable and
telephony subscribers in June 1995.
 
4. SINGTEL TRANSACTION
 
  In March 1996, the Company completed the acquisition (the "SingTel
Transaction") of Singapore Telecom International Pte. Limited's ("Singapore
Telecom") 50% interest in Cambridge Cable, pursuant to the terms of a Share
Exchange Agreement executed by the parties in December 1995. In exchange for
Singapore Telecom's 50% interest in Cambridge Cable and certain loans made to
Cambridge Cable, with accrued interest thereon, the Company issued
approximately 8.9 million of its Class A Common Shares and paid approximately
(Pounds)11.8 million to Singapore Telecom. The Company accounted for the
SingTel Transaction under the purchase method. As a result of the SingTel
Transaction, the Company owns 100% of Cambridge Cable and Cambridge Cable was
consolidated with the Company effective March 31, 1996.
 
  The following unaudited pro forma information for the years ended December
31, 1996 and 1995 has been presented as if the SingTel Transaction had
occurred on January 1, 1995. This unaudited pro forma information is based on
historical results of operations adjusted for acquisition costs and, in the
opinion of management, is not necessarily indicative of what results would
have been had the Company owned 100% of Cambridge Cable since January 1, 1995
(in thousands, except per share data).

5. INVESTMENTS IN AFFILIATES
 
  The Company has historically invested in three affiliates (the "Equity
Investees," which term excludes Cambridge Cable as of, and subsequent to March
31, 1996--see Note 4): Birmingham Cable, Cable London and Cambridge Cable. The
Equity Investees operate integrated cable communications, residential
telephony and

business telecommunications systems in their respective major metropolitan
areas under exclusive cable television licenses and non-exclusive
telecommunications licenses. As of December 31, 1997, the Company's ownership
interest in the Equity Investees is as follows:
 
<TABLE>
       <S>                                                                 <C>
       Birmingham Cable................................................... 27.5%
       Cable London....................................................... 50.0%
</TABLE>
 
  The Company also has a 16.4% interest in Cable Programme Partners-1 Limited
Partnership ("CPP-1") which previously developed and distributed cable
programming in the UK. During 1995, CPP-1 sold its only channel and has wound
down its operations to a minimal level of activity. The carrying value of the
Company's investment in CPP-1 has been reduced to zero and the Company has no
future funding commitments to CPP-1.
 
  Included in investments in affiliates as of December 31, 1997 and 1996, are
loans to Cable London of (Pounds)28.5 million and (Pounds)22.5 million and
accrued interest of (Pounds)6.0 million and (Pounds)3.6 million, respectively.
The loans accrue interest at a rate of 2% above the published base lending
rate of Barclays Bank PLC (9.25% effective rate as of December 31, 1997) and
are subordinate to Cable London's revolving bank credit facility. Of these
loans, (Pounds)21.0 million as of December 31, 1997 and 1996 are convertible
into ordinary shares of Cable London at a per share conversion price of
(Pounds)2.00. Also included in investments in affiliates as of December 31,
1997 are loans to Birmingham Cable of (Pounds)1.9 million and accrued interest
of (Pounds)133,000. The Birmingham Cable loans accrue interest at a fixed rate
of 7.80% and are subordinate to Birmingham Cable's credit facility. Loans to
Cambridge Cable and related accrued interest have been eliminated in
consolidation subsequent to the SingTel Transaction (see Note 4).
 
  In February 1995, a subsidiary of Birmingham Cable issued 175,000 cumulative
(Pounds)1.00 redeemable five year term preference shares for a paid up value
of (Pounds)175.0 million. Also in February 1995, Birmingham Cable entered into
a (Pounds)175.0 million five year revolving credit facility (the "Birmingham
Facility") which provided for conversion into a five year term loan on March
31, 2000. In March 1997, the terms of the Birmingham Facility were amended to
extend the maturity of the term loan to December 31, 2005 and to amend the
required cash flow levels (as defined) and certain other terms. Interest rates
on the Birmingham Facility are at the London Interbank Offered Rate ("LIBOR")
plus 5/8% to 2 1/4%.
 
  In July 1997, the preference shareholder exercised its option to require
Birmingham Cable to purchase its shareholding. Birmingham Cable funded the
redemption of the preference shares with the proceeds from the Birmingham
Facility and restricted cash and settled its five year (Pounds)175.0 million
interest rate exchange agreement with Barclays Bank PLC. The balance of the
Birmingham Facility will be used, subject to certain restrictions, for capital
expenditures and working capital requirements relating to the build-out of its
systems. The preference shares had an effective dividend rate, including
Advanced Corporation Tax ("ACT"), of 8.00%.
 
  The Birmingham Facility contains restrictive covenants which limit
Birmingham Cable's ability to enter into arrangements for the acquisition and
sale of property and equipment, investments, mergers and the incurrence of
additional debt. Certain of these covenants require that certain minimum build
requirements, financial ratios and cash flow levels be maintained and contain
restrictions on dividend payments. Birmingham Cable's three principal
shareholders' (including the Company) right to receive consulting fee payments
from Birmingham Cable has been subordinated to the banks under the Birmingham
Facility. The payment of consulting fees is restricted until Birmingham Cable
meets certain financial ratio tests under the Birmingham Facility. Birmingham
Cable has pledged the shares of its material subsidiaries to secure the
Birmingham Facility. Upon a change of control, all amounts due under the
Birmingham Facility become immediately due and payable. The

                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
consummation of the NTL Transaction will not result in a change of control as
defined in the Birmingham Facility.
 
  In May 1997, Cable London entered into a (Pounds)170.0 million revolving
credit facility (the "London Revolver") with various banks, which converts
into a five year term loan on June 30, 2001. Interest rates on the London
Revolver are at LIBOR plus 1/2% to 2 3/8%. In May 1997, Cable London repaid
all amounts outstanding under its existing credit facility with proceeds from
borrowings under the London Revolver. The balance of the London Revolver will
be used, subject to certain restrictions, for capital expenditures and working
capital requirements relating to the build-out of its systems.
 
  The London Revolver contains restrictive covenants which limit Cable
London's ability to enter into arrangements for the acquisition and sale of
property and equipment, investments, mergers and the incurrence of additional
debt. Certain of these covenants require that certain financial ratios and
cash flow levels be maintained and contain certain restrictions on dividend
payments. The Company's right to receive consulting fee payments from Cable
London has been subordinated to the banks under the London Revolver. The
payment of consulting fees is restricted until Cable London meets certain
financial ratio tests under the London Revolver. In addition, the Company's
shares in Cable London have been pledged to secure the London Revolver. Upon a
change of control, all amounts due under the London Revolver become
immediately due and payable. The consummation of the NTL Transaction will not
result in a change of control as defined in the London Revolver.
 
  Although the Company is not contractually committed to make any additional
capital contributions or advances to any of the Equity Investees, it currently
intends to fund its share of the amounts necessary for capital expenditures
and to finance operating deficits. Failure to do so could dilute the Company's
ownership interests in the Equity Investees.

6. FOREIGN CURRENCY RISK MANAGEMENT
 
  The Company is exposed to market risk including changes in foreign currency
exchange rates. To manage the volatility relating to this exposure, the
Company enters into various derivative transactions pursuant to the Company's
policies in areas such as counterparty exposure and hedging practices.
Positions are monitored using techniques including market value and
sensitivity analyses.
 
  The Company has entered into certain FX Options as a normal part of its
foreign currency risk management efforts. During 1995, the Company entered
into certain foreign exchange put option contracts ("FX Puts") which may be
settled only on November 16, 2000. These FX Puts are used to limit the
Company's exposure to the risk that the eventual cash outflows related to net
monetary liabilities denominated in currencies other than its functional
currency (the UK Pound) (principally the 2007 Discount Debentures--see Note 7)
are adversely affected by changes in exchange rates. As of December 31, 1997
and 1996, the Company had (Pounds)250.0 million notional amount of FX Puts to
purchase US dollars at an exchange rate of $1.35 per (Pounds)1.00 (the
"Ratio"). The FX Puts provide a hedge, to the extent the exchange rate falls
below the Ratio, against the Company's net monetary liabilities denominated in
US dollars since gains and losses realized on the FX Puts are offset against
foreign exchange gains or losses realized on the underlying net liabilities.
Premiums paid for the FX Puts of (Pounds)13.9 million are included in foreign
exchange put options and other in the Company's consolidated balance sheet,
net of related amortization. These premiums are being amortized over the terms
of the related contracts of five years. As of December 31, 1997 and 1996, the
FX Puts had carrying values of (Pounds)8.0 million and (Pounds)10.7 million,
respectively. The estimated fair value of the FX Puts was (Pounds)3.2 million
as of both December 31, 1997 and 1996. The difference between the carrying
amount and the estimated fair value of the FX Puts was not significant as of
December 31, 1995.
 
  In 1995, in order to reduce hedging costs, the Company sold foreign exchange
call option contracts ("FX Calls") to exchange (Pounds)250.0 million notional
amount and received (Pounds)3.4 million. These contracts may only be settled
on their expiration dates. Of these contracts, (Pounds)200.0 million notional
amount, with an exchange ratio of $1.70 per (Pounds)1.00, expired unexercised
in November 1996 while the remaining contract, with a (Pounds)50.0 million
notional amount and an exchange ratio of $1.62 per (Pounds)1.00, has a
settlement date in November 2000. In the fourth quarter of 1996, in order to
continue to reduce hedging costs, the Company sold additional FX Calls for 2.1
million, to exchange (Pounds)200.0 million notional amount at an average
exchange ratio of $1.75 per (Pounds)1.00. These contracts expired unexercised
in the fourth quarter of 1997. The FX Calls are marked-to-market on a current
basis in the Company's consolidated statement of operations.
 
  As of December 31, 1997 and 1996, the estimated fair value of the
liabilities related to the FX Calls, as recorded in the Company's consolidated
balance sheet, was (Pounds)2.7 million and (Pounds)7.2 million, respectively.
Changes in fair value between measurement dates relating to the FX Calls
resulted in exchange gains of (Pounds)4.5 million during the year ended
December 31, 1997 and exchange losses of (Pounds)1.3 million during the year
ended December 31, 1996 in the Company's consolidated statement of operations.
There were not significant exchange gains or losses relating to these
contracts for the year ended December 31, 1995.
 
7. LONG-TERM DEBT
 
 2007 Discount Debentures
 
  In November 1995, the Company received net proceeds of approximately $291.1
million ((Pounds)186.9 million) from the sale of its 2007 Discount Debentures
in a public offering ($517.3 million principal at maturity). Interest accretes
on the 2007 Discount Debentures at 11.20% per annum compounded semi-annually
from November 15,

1995 to November 15, 2000, after which date interest will be paid in cash on
each May 15 and November 15 through November 15, 2007. The accreted value of
the 2007 Discount Debentures was (Pounds)229.2 million and (Pounds)198.1
million as of December 31, 1997 and 1996, respectively.
 
  The 2007 Discount Debentures contain restrictive covenants which limit the
Company's ability to enter into arrangements for the sale of assets, mergers,
the incurrence of additional debt and the payment of dividends. The Company
was in compliance with such restrictive covenants as of December 31, 1997.
Consummation of the NTL Transaction (see Note 1) is subject to consent of the
Company's bondholders.
 
 UK Holdings Credit Facility
 
  On December 23, 1997, UK Holdings entered into a loan agreement (the "UK
Holdings Agreement") with a consortium of banks to provide financing under a
credit facility (the "UK Holdings Credit Facility") up to a maximum of
(Pounds)200.0 million. Under the terms of the UK Holdings Agreement,
borrowings under the UK Holdings Credit Facility are guaranteed by Teesside
and Cambridge Cable.
 
  On January 14, 1998, UK Holdings borrowed (Pounds)75.0 million under Tranche
A of the UK Holdings Credit Facility. Of this initial borrowing, (Pounds)50.4
million was paid to the Company as a dividend and (Pounds)17.8 million was
used to fund capital expenditures and working capital requirements at
Cambridge Cable and Teesside. Amounts available under the UK Holdings Credit
Facility will be reduced each quarter in varying amounts beginning March 31,
2000 and continuing through December 31, 2000. The UK Holdings Credit Facility
bears interest at a rate per annum equal to LIBOR plus 1/2% to 2 1/4%.
 
  The UK Holdings Credit Facility contains restrictive covenants which limit
UK Holdings' ability to enter into arrangements for the acquisition and sale
of property and equipment, investments, mergers and the incurrence of
additional debt. Certain of these covenants require that certain financial
ratios and cash flow levels be maintained and contain certain restrictions on
dividend payments. The Company's right to receive consulting fee payments from
Cambridge Cable and Teesside has been subordinated to the banks under the UK
Holdings Credit Facility. In addition, the Company's shares in UK Holdings
have been pledged to secure the UK Holdings Credit Facility.
 
  The consummation of the NTL Transaction will result in a change in control,
as defined in the UK Holdings Credit Facility. Upon a change in control, all
amounts outstanding under the UK Holdings Credit Facility will become
immediately due and payable.
 
 Other
 
  As of December 31, 1997 and 1996, Cambridge Cable has two outstanding bank
loans totaling (Pounds)505,000 and (Pounds)533,000, respectively, which are
included in long-term debt. These bank loans are secured by Cambridge Cable's
land and buildings in Cambridge and Bishop Stortford and are payable in
quarterly installments through April 2000 and bear interest at a weighted
average fixed rate of 9.35%. Also included in long-term debt are capital lease
obligations of Cambridge Cable and Teesside (see Note 12).
 
  Maturities of long-term debt outstanding, including long-term debt, due to
shareholder (see Note 9), as of December 31, 1997 for the four years after
1998 are as follows (in (Pounds)000's):

  The Company's long-term debt, excluding long-term debt due to shareholder,
had estimated fair values of (Pounds)259.6 million and (Pounds)219.7 million
as of December 31, 1997 and 1996, respectively. The estimated fair value of
the Company's publicly traded debt is based on quoted market prices for that
debt. Interest rates that are currently available to the Company for issuance
of debt with similar terms and remaining maturities are used to estimate fair
value for debt issues for which quoted market prices are not available.
 
8. STOCK OPTION/SAR PLANS
 
  The Company implemented a Stock Appreciation Rights ("SARs") plan during
1995 for certain outside directors under which the terms of the SARs granted
are determined by the Compensation Committee of the Board of Directors (the
"SAR Plan"). Under the SAR Plan, eligible participants are entitled to receive
a cash payment from the Company equal to 100% of the excess, if any, of the
fair market value of a share of the Company's Class A Common Shares at the
time of exercise over the fair market value of such a share at the grant date.
Under the SAR Plan, a total of 50,000 SARs may be granted. The SARs have a
term of ten years from the date of grant and are immediately exercisable. No
SARs were granted in 1997. A total of 6,000 and 15,000 SARs were granted in
1996 and 1995, respectively and 14,000 SARs were outstanding at December 31,
1997, all exercisable. The fair value of the Company's Class A Common Stock at
the grant date of the SARs was $12.63 and $16.25 for 1996 and 1995 grants,
respectively. Compensation expense recorded during the year ended December 31,
1996 was not significant. No compensation expense was recognized during the
years ended December 31, 1997 and December 31, 1995 as the exercise price of
the SARs was not less then the fair value of a share of the Company's Class A
Common Shares.
 
  The Company implemented a qualified stock option plan during 1995 for
certain employees, officers and directors, under which the option prices and
other terms are determined by the Compensation Committee of the Board of
Directors (the "Option Plan"). Under the Option Plan, not more than 250,000 of
the Company's Class A Common Shares may be issued pursuant to the plan upon
exercise of qualified stock options. All options must be granted within ten
years from the date of adoption of the Option Plan, with options becoming
exercisable over four years from the date of grant. A total of 20,250 options,
with an exercise price of $12.63, were granted in 1996 and are outstanding
(none exercisable) at December 31, 1997. No options were granted in 1997 or
1995. No compensation expense has been recognized under the Option Plan as the
exercise price of the grants was not less than the fair market value of the
shares at the grant date. The fair value of the options granted in 1996 was
not significant.
 
9. RELATED PARTY TRANSACTIONS
 
  Comcast U.K. Consulting, Inc. ("UK Consulting"), a wholly owned subsidiary
of the Company, earns consulting fee income under consulting agreements with
the Equity Investees. The consulting fee income is generally based on a
percentage of gross revenues or a fixed amount per dwelling unit in the Equity
Investees' franchise areas.
 
  The Company's right to receive consulting fee payments from Birmingham Cable
and Cable London has been subordinated to the banks under their credit
facilities. Accordingly, a portion of these fees have been classified as long-
term receivables and are included in investments in affiliates in the
Company's consolidated balance sheet. In addition, the Company's shares in
Cable London have been pledged to secure amounts outstanding under the London
Revolver.
 
  Management fee expense is incurred under agreements between the Company on
the one hand, and Comcast, the Company's controlling shareholder, and Comcast
UK Cable Partners Consulting, Inc. ("Comcast

Consulting"), an indirect wholly owned subsidiary of Comcast, on the other,
whereby Comcast and Comcast Consulting provide consulting services to the
Equity Investees on behalf of the Company and management services to the
Company. Such management fees are based on Comcast's and Comcast Consulting's
cost of providing such services. As of December 31, 1997 and 1996, due to
affiliates consists primarily of this management fee and operating expenses
paid by Comcast and its affiliates on behalf of the Company.
 
  Investment income includes (Pounds)2.5 million, (Pounds)2.9 million and
(Pounds)5.0 million of interest income in 1997, 1996 and 1995, respectively,
relating to the loans to Birmingham Cable, Cable London and Cambridge Cable
described in Note 5.
 
  Long-term debt, due to shareholder consists of 9% Subordinated Notes payable
to Holdings (the "Notes") which are due in 1999. During the years ended
December 31, 1997, 1996 and 1995, interest expense on the Notes was
(Pounds)950,000, (Pounds)870,000 and (Pounds)800,000, respectively.
 
  In management's opinion, the foregoing transactions were entered into on
terms no more or less favorable than those with non-affiliated parties.
 
10. INCOME TAXES
 
  The Company's wholly owned subsidiaries have a deferred tax asset arising
from the carryforward of net operating losses and the differences between the
book and tax basis of property. However, a valuation allowance has been
recorded to fully reserve the deferred tax asset as its realization is
uncertain.
 
  Significant components of deferred income taxes are as follows (in
(Pounds)000's):

                         QUARTER ENDED MARCH 31, 1998
                                  (UNAUDITED)
 
1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
 Basis of Presentation
 
  The condensed consolidated balance sheet as of December 31, 1997 has been
condensed from the audited consolidated balance sheet as of that date. The
condensed consolidated balance sheet as of March 31, 1998 and the condensed
consolidated statements of operations and accumulated deficit and of cash
flows for the three months ended March 31, 1998 and 1997 have been prepared by
Comcast UK Cable Partners Limited (the "Company") and have not been audited by
the Company's independent auditors. In the opinion of management, all
adjustments (which include only normal recurring adjustments) necessary to
present fairly the financial position, results of operations and cash flows as
of March 31, 1998 and for all periods presented have been made.
 
  Certain information and note disclosures normally included in the Company's
annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. These condensed
consolidated financial statements should be read in conjunction with the
financial statements and notes thereto included in the Company's December 31,
1997 Annual Report on Form 10-K filed with the Securities and Exchange
Commission. The results of operations for the period ended March 31, 1998 are
not necessarily indicative of operating results for the full year.
 
 Reclassifications
 
  Certain reclassifications have been made to the prior year condensed
consolidated financial statements to conform to those classifications used in
1998.
 
2. AMALGAMATION WITH NTL
 
  On February 4, 1998, the Company entered into a definitive agreement to
amalgamate (the "NTL Transaction") with a wholly owned Bermuda subsidiary of
NTL Incorporated ("NTL"). NTL is an alternative telecommunications company in
the United Kingdom ("UK") and is listed on Nasdaq. The NTL Transaction is
expected to close in 1998, subject to, among other things, the receipt of
required Bermuda and UK regulatory approvals, the approval of the Company's
and NTL's shareholders, the consent of the Company's and NTL's bondholders,
the consent of certain NTL bank lenders and other customary closing matters.
Comcast Corporation ("Comcast"), through its indirect wholly owned subsidiary,
Comcast U.K. Holdings, Inc. ("Holdings"), is the sole holder of the multiple-
voting Class B Common Shares of the Company and has agreed to vote for the
transaction, assuring its approval by the Company's shareholders. Upon
consummation of the NTL Transaction, the Company would become a wholly owned
subsidiary of NTL.
 
  Except in the circumstances described below, the Company's shareholders will
receive 0.3745 shares of NTL common stock for each of the Company's Class A
Common Shares or Class B Common Shares. If the average closing price of the
NTL common stock for a specified period of time prior to the Company's
shareholders meeting to approve the NTL Transaction (the "Average Price") is
less than $26.70, the Company will have the option to terminate the NTL
Transaction, subject to the right of NTL, to adjust the exchange ratio such
that one share of the Company's Class A Common Shares or Class B Common Shares
will be exchanged for a number of shares of NTL common stock equal to $10.00
(based on the Average Price).
 
  Pursuant to existing arrangements between the Company and Telewest
Communications plc ("Telewest"), a co-owner of interests in Cable London PLC
("Cable London") and Birmingham Cable Corporation Limited ("Birmingham
Cable"), Telewest has certain rights (the "Telewest Rights") to acquire either
or both of the

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                         QUARTER ENDED MARCH 31, 1998
Company's interests in these systems (see Note 3) as a result of the NTL
Transaction. However, as described in the following paragraphs, the
consummation of the NTL Transaction is not dependent on the resolution of the
Telewest Rights.
 
  If the Telewest Rights have been exercised prior to the closing of the NTL
Transaction, the Company's shareholders may receive (at the option of NTL), in
lieu of a portion of the consideration allocable to the interest subject to
the exercised Telewest Rights, the per share proceeds from the sale of the
interest to Telewest (net of taxes on gain on sale), payable in cash or shares
of NTL common stock valued at the greater of $30.00 per share or the Average
Price at closing (the "Exercise Consideration").
 
  Similarly, if at closing either of the Telewest Rights have not been
exercised and have not been waived or otherwise expired, the Company's
shareholders may receive (at the option of NTL), shares of a new class of NTL
preferred stock equal to a portion of the consideration allocable to the
interest subject to the unexercised Telewest Rights. Any shares of NTL
preferred stock would have the same voting and dividend rights as shares of
NTL common stock, would be subject to redemption as described below, and would
be expected to be listed for trading on Nasdaq. If following closing the
Telewest Rights are exercised, the NTL preferred stock will be redeemed for
the Exercise Consideration (based on the Average Price at the time of
exercise). If the Telewest Rights are resolved without being exercised, the
NTL preferred stock will be redeemed for NTL common stock on a one-for-one
basis.
 
  Of the consideration to be received by the Company's shareholders in the NTL
Transaction, the parties have allocated 31% to the Company's interest in Cable
London and 17% to the Company's interest in Birmingham Cable. However, if
either or both of the Telewest Rights are exercised, the actual consideration
to be received by the Company's shareholders may be materially different from
the portion of the consideration (the "allocable portion") which has been
allocated by the parties to the Company's respective interests in Cable London
and Birmingham Cable, depending on, among other things, the value of these
interests, as finally determined, whether NTL exercises its option to deliver
the Exercise Consideration in lieu of the allocable portion and, the amount of
any taxes payable by the Company on the sale of those interests.
 
3. INVESTMENTS IN AFFILIATES
 
  The Company has invested in two affiliates: Birmingham Cable and Cable
London (together, the "Equity Investees"). The Equity Investees operate
integrated cable communications, residential telephony and business
telecommunications systems in their respective major metropolitan areas under
exclusive cable television licenses and non-exclusive telecommunications
licenses. As of March 31, 1998, the Company's ownership interest in the Equity
Investees is as follows:

       Birmingham Cable................................................... 27.5%
       Cable London....................................................... 50.0%
</TABLE>
 
  Included in investments in affiliates as of March 31, 1998 and December 31,
1997, are loans to Cable London of (Pounds)28.5 million and accrued interest
of (Pounds)6.7 million and (Pounds)6.0 million, respectively. The loans accrue
interest at a rate of 2% above the published base lending rate of Barclays
Bank plc (9.25% effective rate as of March 31, 1998) and are subordinate to
Cable London's credit facility. Of these loans, (Pounds)21.0 million as of
March 31, 1998 and December 31, 1997, are convertible into ordinary shares of
Cable London at a per share conversion price of (Pounds)2.00. Also included in
investments in affiliates as of March 31, 1998 and December 31, 1997, are
loans to Birmingham Cable of (Pounds)3.7 million and (Pounds)1.9 million and
accrued interest of (Pounds)177,000 and (Pounds)133,000, respectively. The
Birmingham Cable loans accrue interest at a fixed rate of 7.8% and are
subordinate to Birmingham Cable's credit facility.

  Although the Company is not contractually committed to make any additional
capital contributions or advances to the Equity Investees, it currently
intends to fund its share of the amounts necessary for capital expenditures
and to finance operating deficits. Failure to do so could dilute the Company's
ownership interests in the Equity Investees.
 
  Summarized financial information for affiliates accounted for under the
equity method is as follows:

4. LONG-TERM DEBT
 
 UK Holdings Credit Facility
 
  In December 1997, Comcast UK Holdings Limited ("UK Holdings"), a wholly
owned subsidiary of the Company, entered into a loan agreement (the "UK
Holdings Agreement") with a consortium of banks to provide financing under a
credit facility (the "UK Holdings Credit Facility") up to a maximum of
(Pounds)200.0 million. Under the terms of the UK Holdings Agreement,
borrowings under the UK Holdings Credit Facility are guaranteed by Cambridge
Holding Company Limited ("Cambridge Cable") and two companies holding the
franchises for Darlington and Teesside, England ("Teesside"). Cambridge Cable
and Teesside are wholly owned subsidiaries of the Company.
 
  In January 1998, UK Holdings borrowed (Pounds)75.0 million under the UK
Holdings Credit Facility. Of this initial borrowing, (Pounds)50.4 million was
paid to the Company as a dividend and (Pounds)17.8 million was used to fund
capital expenditures and working capital requirements at Cambridge Cable and
Teesside. Final maturity of the UK Holdings Credit Facility is January 31,
2001. The UK Holdings Credit Facility bears interest at a rate per annum

equal to the London Interbank Official Rate ("LIBOR") plus 1/2% to 2 1/4%. As
of March 31, 1998 the Company's effective weighted average interest rate on
the UK Holdings Credit Facility was 9.47%.
 
  The consummation of the NTL Transaction will result in a change in control,
as defined in the UK Holdings Credit Facility. Upon a change in control, all
amounts outstanding under the UK Holdings Credit Facility will become
immediately due and payable.
 
5. RELATED PARTY TRANSACTIONS
 
  Comcast U.K. Consulting, Inc., a wholly owned subsidiary of the Company,
earns consulting fee income under consulting agreements with the Equity
Investees. The consulting fee income is generally based on a percentage of
gross revenues or a fixed amount per dwelling unit in the Equity Investees'
franchise areas.
 
  The Company's right to receive consulting fee payments from the Equity
Investees has been subordinated to the banks under their credit facilities.
Accordingly, these fees have been classified as long-term receivables and are
included in investments in affiliates in the Company's condensed consolidated
balance sheet. In addition, the Company's shares in Cable London have been
pledged to secure amounts outstanding under Cable London's revolving credit
facility.
 
  Management fee expense is incurred under agreements between the Company on
the one hand, and Comcast, the Company's controlling shareholder, and Comcast
UK Cable Partners Consulting, Inc. ("Comcast Consulting"), an indirect wholly
owned subsidiary of Comcast, on the other, whereby Comcast and Comcast
Consulting provide consulting services to the Equity Investees on behalf of
the Company and management services to the Company. Such management fees are
based on Comcast's and Comcast Consulting's cost of providing such services.
As of March 31, 1998 and December 31, 1997, due to affiliates consists
primarily of this management fee and operating expenses paid by Comcast and
its affiliates on behalf of the Company.
 
  For the three months ended March 31, 1998 and 1997, investment income
includes (Pounds)694,000 and (Pounds)529,000 of interest income, respectively,
relating to the loans to the Equity Investees.
 
  Long-term debt due to shareholder consists of 9% Subordinated Notes payable
to Holdings which are due in September 1999. For the three months ended March
31, 1998 and 1997, the Company recorded (Pounds)245,000 and (Pounds)224,000,
respectively, of interest expenses relating to such notes.
 
  In management's opinion, the foregoing transactions were entered into on
terms no more or less favorable than those with non-affiliated parties.
 
6. CONTINGENCIES
 
  The Company is subject to legal proceedings and claims which arise in the
ordinary course of its business. In the opinion of management, the amount of
ultimate liability with respect to these actions will not materially affect
the financial position, results of operations or liquidity of the Company.
 
7. STATEMENT OF CASH FLOWS--SUPPLEMENTAL INFORMATION
 
  The Company made cash payments for interest of (Pounds)1.6 million and
(Pounds)135,000 during the three months ended March 31, 1998 and 1997,
respectively.
 
  The Company's wholly owned subsidiaries incurred capital lease obligations
of (Pounds)1.3 million during the three months ended March 31, 1998.

                         INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
Birmingham Cable Corporation Limited
 
  We have audited the accompanying consolidated balance sheet of Birmingham
Cable Corporation Limited (a company incorporated in the United Kingdom) and
subsidiaries as of December 31, 1997 and 1996, and the related consolidated
statements of operations, shareholders' equity and of cash flows for each of
the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Birmingham Cable Corporation
Limited and subsidiaries as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1997 in conformity with accounting principles
generally accepted in the United States of America.

             BIRMINGHAM CABLE CORPORATION LIMITED AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
1. BUSINESS
 
  Birmingham Cable Corporation Limited, a company incorporated in the United
Kingdom ("UK"), and subsidiaries (the "Company") is principally engaged in the
development, construction, management and operation of cable
telecommunications systems. The Company holds two franchises in
Birmingham/Solihull and Wythall, England.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Accounting
 
  The Company maintains its books and records in accordance with accounting
principles generally accepted in the UK. The consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
as practiced in the United States ("US") and are stated in UK pounds sterling
("UK Pound"). There were no significant differences between accounting
principles followed for UK purposes and generally accepted accounting
principles practiced in the US. The UK Pound exchange rate as of December 31,
1997 and 1996 was US $1.65 and US $1.71, respectively.
 
 Basis of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and all wholly owned subsidiaries. All significant intercompany accounts and
transactions among the consolidated entities have been eliminated.
 
 Management's Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Values
 
  The estimated fair value amounts presented in these notes to consolidated
financial statements have been determined by the Company using available
market information and appropriate methodologies. However, considerable
judgment is required in interpreting market data to develop the estimates of
fair value. The estimates presented herein are not necessarily indicative of
the amounts that the Company could realize in a current market exchange. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts. Such fair value estimates
are based on pertinent information available to management as of December 31,
1997 and 1996, and have not been comprehensively revalued for purposes of
these consolidated financial statements since such dates.
 
 Cash, Cash Equivalents and Restricted Cash
 
  Cash, cash equivalents and restricted cash as of December 31, 1996 included
cash held on deposit as part of a (Pounds)175.0 million financing arrangement
entered into by the Company in 1995. In July 1997 this arrangement was
restructured and the restricted cash was used, together with proceeds from the
Birmingham Facility, to redeem the preference shares (see Note 3).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
 
 Prematurity Period
 
  The Company accounts for costs, expenses and revenues applicable to the
construction and operation of its cable telecommunications systems under the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 51,
"Financial Reporting by Cable Television Companies."
 
  Under SFAS No. 51, during the period while the systems are partially under
construction and partially in service (the "Prematurity Period"), costs of
cable telecommunications plant, including materials, direct labor and
construction overhead are capitalized. Subscriber-related costs and general
and administrative costs are expensed as incurred. Costs incurred in
anticipation of servicing a fully operating system that will not vary
regardless of the number of subscribers are partially expensed and partially
capitalized, based upon the percentage of average actual or estimated
subscribers, whichever is greater, to the total number of subscribers expected
at the end of the Prematurity Period (the "Fraction").
 
  During the Prematurity Period, depreciation and amortization of system
assets is determined by multiplying the depreciation and amortization of the
total capitalized system assets expected at the end of the Prematurity Period
by the Fraction. At the end of the Prematurity Period, depreciation and
amortization of system assets is based on the remaining undepreciated cost at
that date.
 
  As of December 31, 1997, all of the Company's seven discrete build areas
have completed their Prematurity Period.
 
 Property and Equipment
 
  Property and equipment, which consists principally of system assets, is
shown at historical cost less accumulated depreciation. Improvements that
extend asset lives are capitalized; other repairs and maintenance charges are
expensed as incurred. The cost and related accumulated depreciation applicable
to assets sold or retired are removed from the accounts and the gain or loss
on disposition is recognized as a component of depreciation expense.
 
 System assets
 
  Prior to the Prematurity Period, no depreciation is provided on system
assets. During the Prematurity Period, depreciation is provided in accordance
with SFAS No. 51.
 
  Depreciation of system assets is provided by the straight-line method over
estimated useful lives as follows:

</TABLE>
 
 Leased Assets
 
  Assets held under capital leases are treated as if they had been purchased
outright and the corresponding liability is included in capital lease
obligations. Capital lease payments include principal and interest, with the
interest portion being expensed. Payments on operating leases are expensed on
a straight-line basis over the lease term.
 
 Deferred Charges
 
  Deferred charges consist primarily of franchise acquisition and development
costs directly attributable to obtaining, developing and maintaining the
franchise licenses. Franchise acquisition and development costs have been
allocated evenly between each build area and are amortized, by build area, on
a straight-line basis, over the lives of the franchises of 15 to 23 years.
 
 Valuation of Long-Lived Assets
 
  The Company periodically evaluates the recoverability of its long-lived
assets, including property and equipment and deferred charges, using objective
methodologies. Such methodologies include evaluations based on the cash flows
generated by the underlying assets or other determinants of fair value.
 
 Revenue Recognition
 
  Service income is recognized as service is provided. Credit risk is managed
by disconnecting services to subscribers who are delinquent.
 
 Income Taxes
 
  The Company recognizes deferred tax assets and liabilities for temporary
differences between the financial reporting basis and the tax basis of the
Company's assets and liabilities and expected benefits of utilizing net
operating loss carryforwards. The impact on deferred taxes of changes in tax
rates and laws, if any, applied to the years during which temporary
differences are expected to be settled, are reflected in the financial
statements in the period of enactment.
 
 Derivative Financial Instruments
 
  The Company uses interest rate exchange agreements ("Swaps"), to manage its
exposure to fluctuations in interest rates. Swaps are matched with either
fixed or variable rate debt and periodic cash payments are accrued on a
settlement basis as an adjustment to interest expense.

  Those instruments that have been entered into by the Company to hedge
exposure to interest rate risks are periodically examined by the Company to
ensure that the instruments are matched with underlying liabilities, reduce
the Company's risks relating to interest rates and, through market value and
sensitivity analysis, maintain a high correlation to the interest expense or
underlying value of the hedged item.
 
  The Company does not hold or issue any derivative financial instruments for
trading purposes and is not a party to any leveraged instruments (see Note 3).
The credit risks associated with the Company's derivative financial
instruments are controlled through the evaluation and monitoring of the
creditworthiness of the counterparties. Although the Company may be exposed to
losses in the event of nonperformance by the counterparties, the Company does
not expect such losses, if any, to be significant.
 
 Reclassifications
 
  Certain reclassifications have been made to the prior years' consolidated
financial statements to conform to those classifications used in 1997.
 
3. LONG-TERM DEBT AND PREFERENCE SHARES
 
  In February 1995, a subsidiary of the Company issued 175,000 cumulative
(Pounds)1.00 redeemable five year term preference shares for a paid up value
of (Pounds)175.0 million. Also in February 1995, the Company entered into a
(Pounds)175.0 million five year revolving credit facility (the "Birmingham
Facility") which provided for conversion into a five year term loan on March
31, 2000. In March 1997, the terms of the Birmingham Facility were amended to
extend the maturity of the term loan to December 31, 2005 and to amend the
required cash flow levels (as defined) and certain other terms. Interest rates
on the Birmingham Facility are at the London Interbank Offered Rate ("LIBOR")
plus 5/8% to 2 1/4%.
 
  In July 1997, the preference shareholder exercised its option to require the
Company to purchase its shareholding. The Company funded the redemption of the
preference shares with the proceeds from the Birmingham Facility and
restricted cash and settled its five year (Pounds)175.0 million interest rate
exchange agreement with Barclays Bank PLC. The balance of the Birmingham
Facility will be used, subject to certain restrictions, for capital
expenditures and working capital requirements relating to the build-out of its
systems. The preference shares had an effective dividend rate, including
Advanced Corporation Tax ("ACT"), of 8.00%.
 
  The Birmingham Facility contains restrictive covenants which limit the
Company's ability to enter into arrangements for the acquisition and sale of
property and equipment, investments, mergers and the incurrence of additional
debt. Certain of these covenants require that certain minimum build
requirements, financial ratios and cash flow levels be maintained and contain
restrictions on dividend payments. The Company's three principal shareholders'
right to receive consulting fee payments from the Company has been
subordinated to the banks under the Birmingham Facility. The payment of
consulting fees is restricted until the Company meets certain financial ratio
tests under the Birmingham Facility. The Company has pledged the shares of its
material subsidiaries to secure the Birmingham Facility. Upon a change of
control, all amounts due under the Birmingham Facility become immediately due
and payable. On February 4, 1998, Comcast UK Cable Partners Limited ("Comcast
UK"), one the Company's principal shareholders, entered into a definitive
agreement to amalgamate (the "NTL Transaction") with a wholly owned subsidiary
of NTL Incorporated. The consummation of the NTL Transaction will not result
in a change of control as defined in the Birmingham Facility.
 
  The Company enters into Swaps as a normal part of its risk management
efforts to limit its exposure to adverse fluctuations in interest rates. Using
Swaps, the Company agrees to exchange, at specified intervals, the
 
                                     F-72

difference between fixed and variable interest amounts calculated by reference
to an agreed upon notional amount. In conjunction with the Birmingham
Facility, a subsidiary of the Company and Barclays Bank PLC entered into a
five year (Pounds)175.0 million Swap, whereby the subsidiary receives fixed
interest at a rate of 8.83% and pays floating rate interest at the six month
LIBOR. The (Pounds)175.0 million Swap was settled in July 1997 along with the
redemption of the preference shares (see above). In addition, a subsidiary of
the Company entered into a second series of five year Swaps with three banks.
Under the agreements, the subsidiary pays fixed rate interest at 9.20% and
receives floating rate interest at six month LIBOR, based upon the outstanding
notional amount of the Swaps. As of December 31, 1997 and 1996, the notional
amount outstanding on the second series of Swaps was (Pounds)149.0 million and
(Pounds)106.0 million, respectively, and increased to (Pounds)160.0 million on
January 2, 1998. The notional amounts of interest rate agreements are used to
measure interest to be paid or received and do not represent the amount of
exposure to credit loss. While Swaps represent an integral part of the
Company's interest rate risk management program, their incremental effect on
interest expense for the years ended December 31, 1997, 1996 and 1995 was not
significant. The estimated amount to settle the Company's Swaps was a
liability of (Pounds)7.5 million and a receivable of (Pounds)168,000 as of
December 31, 1997 and 1996, respectively.
 
  On March 16, 1998, the Company's shareholders loaned (Pounds)7.0 million to
the Company in the form of Junior Subordinated Debt, as defined in the
Birmingham Facility. The proceeds from this borrowing were used to settle the
Swaps described above. Additionally, on March 16, 1998 a subsidiary of the
Company entered into a (Pounds)160.0 million notional amount two year Swap
with three banks. Under the terms of this Swap, the subsidiary pays fixed rate
interest at 7.23% and receives floating rate interest at six month LIBOR,
based upon the notional amount.
 
  Maturities of long-term debt outstanding as of December 31, 1997 for the
four years after 1998 are as follows ((Pounds)000's):
 
<TABLE>
       <S>                                                           <C>

       2002.........................................................      21,000
</TABLE>
 
  The differences between the carrying amounts and estimated fair value of the
Company's long-term debt was not significant as of December 31, 1997 and 1996.
Interest rates that are currently available to the Company for debt with
similar terms and remaining maturities are used to estimate fair value for
debt issues for which quoted market prices are not available.
 
4. LONG-TERM DEBT, DUE TO SHAREHOLDERS
 
  As of December 31, 1997, the Company had outstanding loans from shareholders
of (Pounds)7.0 million and accrued interest thereon of (Pounds)492,000. The
loans from shareholders bear interest at a fixed rate of 7.8% and are payable
on demand. Under the terms of the Birmingham Facility, however, principal and
interest on the loans from shareholders cannot be paid until the Birmingham
Facility is repaid. Thus, the loans from shareholders and accrued interest
thereon have been classified as long-term in the Company's consolidated
balance sheet. A reasonable estimate of the fair value of the loans from
shareholders is not practicable to obtain because of the related party nature
of these items and the lack of quoted market prices.
 
5. RELATED PARTY TRANSACTIONS
 
  The Company has consulting agreements with Comcast U.K. Consulting, Inc.
("Comcast Consulting") and Telewest Communications Group Ltd., subsidiaries of
two of the Company's principal shareholders, Comcast

UK and Telewest Communications plc ("Telewest"), respectively. The Company
also has a consulting agreement with General Cable, the Company's other
principal shareholder. The Company pays a fee to Telewest each year as a
contribution to the operating expenses and capital expenditures of Telewest's
Network Service Center, which provides telephony support to the Company. The
Company has a telephony interconnect agreement with Telewest, whereby certain
telephony traffic is routed via Telewest. These interconnect costs are
included in "other" below.

  As of December 31, 1997 and 1996, accounts payable and accrued expenses
include (Pounds)1.4 million and (Pounds)2.3 million, respectively, payable to
the Company's three principal shareholders, principally for consulting fees
and normal operating expenses paid by the shareholders and their affiliates on
behalf of the Company. As of December 31, 1997 and 1996, other long-term
liabilities includes (Pounds)3.9 million and (Pounds)1.3 million,
respectively, of consulting fees payable to the Company's three principal
shareholders as payment is restricted under the Birmingham Facility.
 
  In management's opinion, the foregoing transactions were entered into on
terms no more or less favorable than those with non-affiliated third parties.
 
6. INCOME TAXES
 
  The Company has a deferred tax asset arising from the carryforward of net
operating losses and the differences between the book and tax basis of
property. However, a valuation allowance has been recorded to fully reserve
the deferred tax asset as its realization is uncertain.
 
  Significant components of the Company's deferred income taxes are as follows

  In connection with the Birmingham Facility and the related preference share
arrangement (see Note 3), the Company is obligated to pay ACT on all
preference share dividends. Related ACT for 1997, 1996 and 1995 was
(Pounds)1.4 million, (Pounds)2.8 million and (Pounds)2.5 million,
respectively, and has been classified as a component of interest expense in
the Company's consolidated statement of operations. ACT may be carried forward
indefinitely to offset potential future tax liabilities of the Company.

an agreement with the local authority to service and maintain the Company's
satellite master antenna television installations in the franchise area. This
liability is noninterest bearing and will be discharged by the payment of
(Pounds)95,000 annually through 2003. The effect of discounting the liability
is not significant to the Company's financial position or results of
operations.

                         INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
Cable London PLC
 
  We have audited the accompanying consolidated balance sheet of Cable London
PLC (a company incorporated in the United Kingdom) and subsidiaries as of
December 31, 1997 and 1996, and the related consolidated statements of
operations, shareholders' (deficiency) equity and of cash flows for each of
the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Cable London PLC and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with accounting principles generally
accepted in the United States of America.

                       CABLE LONDON PLC AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
1. BUSINESS
 
  Cable London PLC, a company incorporated in the United Kingdom ("UK"), and
subsidiaries (the "Company") is principally engaged in the development,
construction, management and operation of cable telecommunications systems.
The Company holds four franchises covering Camden, Haringey, Hackney/
Islington and Enfield, England.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Accounting
 
  The Company maintains its books and records in accordance with accounting
principles generally accepted in the UK. The consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
as practiced in the United States ("US") and are stated in UK pounds sterling
("UK Pound"). There were no significant differences between accounting
principles followed for UK purposes and generally accepted accounting
principles practiced in the US. The UK Pound exchange rate as of December 31,
1997 and 1996 was US $1.65 and US $1.71, respectively.
 
 Basis of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and all wholly owned subsidiaries. All significant intercompany accounts and
transactions among the consolidated entities have been eliminated.
 
 Management's Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Values
 
  The estimated fair value amounts presented in these notes to consolidated
financial statements have been determined by the Company using available
market information and appropriate methodologies. However, considerable
judgment is required in interpreting market data to develop the estimates of
fair value. The estimates presented herein are not necessarily indicative of
the amounts that the Company could realize in a current market exchange. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts. Such fair value estimates
are based on pertinent information available to management as of December 31,
1997 and 1996, and have not been comprehensively revalued for purposes of
these consolidated financial statements since such dates.
 
 Prematurity Period
 
  The Company accounts for costs, expenses and revenues applicable to the
construction and operation of its cable telecommunications systems under the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 51,
"Financial Reporting by Cable Television Companies."
 
  Under SFAS No. 51, during the period while the systems are partially under
construction and partially in service (the "Prematurity Period"), costs of

and construction overhead are capitalized. Subscriber-related costs and
general and administrative costs are expensed as incurred. Costs incurred in
anticipation of servicing a fully operating system that will not vary
regardless of the number of subscribers are partially expensed and partially
capitalized, based on the percentage of average actual or estimated
subscribers, whichever is greater, to the total number of subscribers expected
at the end of the Prematurity Period (the "Fraction").
 
  During the Prematurity Period, depreciation and amortization of system
assets is determined by multiplying the depreciation and amortization of the
total capitalized system assets expected at the end of the Prematurity Period
by the Fraction. At the end of the Prematurity Period, depreciation and
amortization of system assets is based on the remaining undepreciated cost at
that date.
 
  As of December 31, 1997, three of the Company's four franchise areas have
completed their Prematurity Period. The remaining Prematurity Period is
expected to terminate in 1998.
 
 Property and Equipment
 
  Property and equipment, which consists principally of system assets, is
shown at historical cost less accumulated depreciation. Improvements that
extend asset lives are capitalized; other repairs and maintenance charges are
expensed as incurred. The cost and related accumulated depreciation applicable
to assets sold or retired are removed from the accounts and the gain or loss
on disposition is recognized as a component of depreciation expense.
 
 System assets
 
  Prior to the Prematurity Period, no depreciation is provided on system
assets. During the Prematurity Period, depreciation is provided in accordance
with SFAS No. 51.
 
  Depreciation of system assets is provided by the straight-line method over
estimated useful lives as follows:

 Leased Assets
 
  Assets held under capital leases are treated as if they had been purchased
outright and the corresponding liability is included in capital lease
obligations. Capital lease payments include principal and interest, with the

interest portion being expensed. Payments on operating leases are expensed on
a straight-line basis over the lease term.
 
 Deferred Charges
 
  Deferred charges consist primarily of franchise acquisition and development
costs directly attributable to obtaining, developing and maintaining the
franchise licenses and debt acquisition costs incurred by the Company in
entering into the London Revolver (see Note 3). Franchise acquisition and
development costs are being amortized on a straight-line basis over periods
from two to fifteen years. Debt acquisition costs are being amortized on a
straight-line basis over the term of the London Revolver of nine years.
 
 Valuation of Long-Lived Assets
 
  The Company periodically evaluates the recoverability of its long-lived
assets, including property and equipment and deferred charges, using objective
methodologies. Such methodologies include evaluations based on the cash flows
generated by the underlying assets or other determinants of fair value.
 
 Revenue Recognition
 
  Service income is recognized as service is provided. Credit risk is managed
by disconnecting services to subscribers who are delinquent.
 
 Income Taxes
 
  The Company recognizes deferred tax assets and liabilities for temporary
differences between the financial reporting basis and the tax basis of the
Company's assets and liabilities and expected benefits of utilizing net
operating loss carryforwards. The impact on deferred taxes of changes in tax
rates and laws, if any, applied to the years during which temporary
differences are expected to be settled, are reflected in the financial
statements in the period of enactment.
 
 Derivative Financial Instruments
 
  The Company uses derivative financial instruments, including interest rate
exchange agreements ("Swaps") and interest rate collar agreements ("Collars"),
to manage its exposure to fluctuations in interest rates.
 
  Swaps and Collars are matched with either fixed or variable rate debt and
periodic cash payments are accrued on a settlement basis as an adjustment to
interest expense.
 
  Those instruments that have been entered into by the Company to hedge
exposure to interest rate risks are periodically examined by the Company to
ensure that the instruments are matched with underlying liabilities, reduce
the Company's risks relating to interest rates and, through market value and
sensitivity analysis, maintain a high correlation to the interest expense or
underlying value of the hedged item.
 
  The Company does not hold or issue any derivative financial instruments for
trading purposes and is not a party to leveraged instruments (see Note 3). The
credit risks associated with the Company's derivative financial instruments
are controlled through the evaluation and monitoring of the creditworthiness
of the counterparties. Although the Company may be exposed to losses in the
event of nonperformance by the counterparties, the Company does not expect
such losses, if any, to be significant.

 Reclassifications
 
  Certain reclassifications have been made to the prior years' consolidated
financial statements to conform to those classifications used in 1997.
 
3. LONG-TERM DEBT
 
  In June 1995, the Company entered into a (Pounds)60.0 million revolving
credit facility (the "London Facility") with various banks. The London
Facility had a two year term and an interest rate at the London Interbank
Offered Rate ("LIBOR") plus 2 1/2%. In April 1997, the amount available under
the London Facility was increased to (Pounds)65.0 million.
 
  In May 1997, the Company entered into a (Pounds)170.0 million revolving
credit facility (the "London Revolver") with various banks, which converts
into a five year term loan on June 30, 2001. Interest rates on the London
Revolver are at LIBOR plus 1/2% to 2 3/8%. In May 1997, the Company repaid all
amounts outstanding under the London Facility with proceeds from borrowings
under the London Revolver. The balance of the London Revolver will be used,
subject to certain restrictions, for capital expenditures and working capital
requirements relating to the build-out of its systems.
 
  The London Revolver contains restrictive covenants which limit the Company's
ability to enter into arrangements for the acquisition and sale of property
and equipment, investments, mergers and the incurrence of additional debt.
Certain of these covenants require that certain financial ratios and cash flow
levels be maintained and contain certain restrictions on dividend payments.
The Company's two principal shareholders' rights to receive consulting fee
payments from the Company has been subordinated to the banks under the London
Revolver. The payment of consulting fees is restricted until the Company meets
certain financial ratio tests under the London Revolver. In addition, the
Company's two principal shareholders' shares in the Company have been pledged
to secure the London Revolver. Upon a change of control, all amounts due under
the London Revolver become immediately due and payable. On February 4, 1998,
Comcast UK Cable Partners Limited ("Comcast UK"), one the Company's principal
shareholders, entered into a definitive agreement to amalgamate (the "NTL
Transaction") with a wholly owned subsidiary of NTL Incorporated. The
consummation of the NTL Transaction will not result in a change of control as
defined in the London Revolver.
 
  The Company enters into Swaps and Collars as a normal part of its risk
management efforts to limit its exposure to adverse fluctuations in interest
rates. Using Swaps, the Company agrees to exchange, at specified intervals,
the difference between fixed and variable interest amounts calculated by
reference to an agreed upon notional amount. Collars limit the Company's
exposure to and benefits from interest rate fluctuations on variable rate debt
to within a certain range of interest rates. In June 1997, the Company entered
into a series of four year interest Swaps with three banks. Under the
agreements, the Company pays fixed rate interest at 7.34% and receives
floating rate interest at three month LIBOR, based upon the outstanding
notional amount of the Swaps. As of December 31, 1997, the notional amount
outstanding on the Swaps was (Pounds)44.5 million and increased to
(Pounds)49.5 million on January 7, 1998. Also in June 1997, the Company
entered into a Collar which limits the interest rate on the notional amount to
between 6% and 9%. As of December 31, 1997, the notional amount outstanding on
the Collar was (Pounds)22.3 million and increased to (Pounds)24.8 million on
January 7, 1998. The notional amounts of interest rate agreements and interest
rate collar agreements are used to measure interest to be paid or received and
do not represent the amount of exposure to credit loss. While Swaps and
Collars represent an integral part of the Company's interest rate risk
management program, their incremental effect on interest expense for the year
ended December 31, 1997 was not significant. The estimated amount to settle
the Company's Swaps and Collar was (Pounds)1.5 million as of December 31,
1997.

  Also included in long-term debt is a mortgage note payable with an
outstanding balance of (Pounds)753,000 and (Pounds)755,000 as of December 31,
1997 and 1996, respectively, payable in monthly installments through 2002
which is secured by property of the Company. The mortgage note bears interest
at a fixed rate of 9.79%.
 
  Maturities of long-term debt outstanding as of December 31, 1997 for the
four years after 1998 are as follows ((Pounds)000's):
 
<TABLE>
       <S>                                                          <C>

       2002........................................................        8,900
</TABLE>
 
  The differences between the carrying amounts and estimated fair value of the
Company's long-term debt was not significant as of December 31, 1997 and 1996.
Interest rates that are currently available to the Company for debt with
similar terms and remaining maturities are used to estimate fair value for
debt issues for which quoted market prices are not available.
 
4. CONVERTIBLE DEBT AND LOANS FROM SHAREHOLDERS
 
  As of December 31, 1997 and 1996, the Company had outstanding convertible
debt due to shareholders of (Pounds)42.0 million and outstanding loans from
shareholders of (Pounds)15.0 million and (Pounds)3.0 million, respectively.
The convertible debt and loans from shareholders bear interest at 2% above the
base lending rate of Barclays Bank PLC (9.25% effective rate as of December
31, 1997) and are payable on demand. Accrued interest on the convertible debt
and loans from shareholders is (Pounds)12.0 million and (Pounds)7.2 million as
of December 31, 1997 and 1996, respectively. Under the terms of the London
Revolver, principal and interest on the convertible debt and loans from
shareholders cannot be paid until the London Revolver is repaid. Accordingly,
the convertible debt, loans from shareholders and accrued interest thereon has
been classified as long-term convertible debt and other in the Company's
consolidated balance sheet. The convertible debt, along with accrued interest
thereon, is convertible into the Company's ordinary shares at (Pounds)2.00 per
share. Interest expense on the convertible debt and loans from shareholders
was (Pounds)4.8 million, (Pounds)3.3 million and (Pounds)3.2 million during
the years ended December 31, 1997, 1996 and 1995, respectively. A reasonable
estimate of the convertible debt and loans from shareholders is not
practicable to obtain because of the related party nature of these items and
the lack of quoted market prices.
 
5. RELATED PARTY TRANSACTIONS
 
  The Company has consulting agreements with Comcast U.K. Consulting, Inc.
("Comcast Consulting") and Telewest Communications Group Ltd., subsidiaries of
the Company's two principal shareholders, Comcast UK and Telewest
Communications plc ("Telewest"), respectively. The Company pays a fee to
Telewest each year as a contribution to the operating expenses and capital
expenditures of Telewest's Network Service Center, which provides telephony
support to the Company.
 
  A summary of related party charges included in the Company's consolidated
financial statements is as follows (in (Pounds)000's):

  As of December 31, 1997 and 1996, accounts payable and accrued expenses
include (Pounds)176,000 million and (Pounds)1.6 million, respectively, payable
to the Company's two principal shareholders, principally for consulting fees
and normal operating expenses paid by the shareholders and their affiliates on
behalf of the Company. As of December 31, 1997 other long-term liabilities
includes (Pounds)2.5 million of consulting fees and interest payable to the
Company's two principal shareholders as payment is restricted under the London
Revolver.
 
  In management's opinion, the foregoing transactions were entered into on
terms no more or less favorable than those with non-affiliated third parties.
 
6. INCOME TAXES
 
  The Company has a deferred tax asset arising from the carryforward of net
operating losses and the differences between the book and tax basis of
property. However, a valuation allowance has been recorded to fully reserve
the deferred tax asset as its realization is uncertain.
 
  Significant components of the Company's deferred income taxes are as follows

                                    PART II
 
                  INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  As permitted by Section 102 of the Delaware General Corporation Law (the
"DGCL"), the Company's Restated Certificate of Incorporation (the "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 By-laws (the "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 right 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 is fairly and reasonably entitled to
indemnity 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 By-laws 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 of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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
of 1933 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 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 notes 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.

          (b)  Neither the Company, nor any of its Affiliates, (as defined in

          (h)  The Company is not an "investment company" within the meaning of

          (i)  The Company and each of its subsidiaries has been duly

     corporation authorized to do business in each jurisdiction in which the
     nature of its business or its ownership or leasing of property requires
     such qualification, except where the failure to be so qualified or in good
     standing would not have a material adverse effect on the business,
     financial condition or results of operations of the Company and its
     subsidiaries, taken as a whole.

          (j)  Neither the Company nor any of its subsidiaries is in violation
     of its respective certificate of incorporation or by-laws or other
     governing documents or is in default in the performance of any obligation,

     Subsidiaries (as defined in the Indentures) is a party or by which it or
     any of its Material Subsidiaries is bound or to which any of their
     respective properties is subject or, except as referred to in the
     Preliminary Offering Memorandum and the Final Offering Memorandum, is in
     violation of any law, statute, rule, regulation, judgment or court decree
     applicable to the Company or any of its Material Subsidiaries or any of
     their respective properties (including any laws, statutes, rules or
     regulations promulgated by the Independent Television Commission ("ITC"),
                                                                        ---   
     the Office of Telecommunications ("OFTEL") and the Department of Trade and
                                        -----                                  
     Industry ("DTI")), nor has any event occurred which with notice or lapse of
                ---                                                             
     time or both would constitute such a violation or default, except in each
     case, which would not have a material adverse effect on the business,
     financial condition or results of operations of the Company and its
     subsidiaries, taken as a whole.

          (k)  The Company has all requisite corporate power and authority to
     execute, deliver and perform its obligations under this Agreement, the
     Indentures and the Registration Rights Agreements and to issue, sell and
     deliver the Securities as provided herein and therein.

          (l)  The (i) issuance and sale of the Securities by the Company, (ii)
     execution, delivery and performance of this Agreement, the Indentures and
     the Registration Rights Agreements, (iii) compliance by the Company with
     the provisions of the Securities, this Agreement, the Indentures and the
     Registration Rights Agreements, and (iv) consummation of the transactions
     contemplated by any of the Securities, this Agreement, the Indentures and
     the Registration Rights Agreements, will not require any consent, approval,
     authorization or other order of any court, regulatory body, administrative
     agency or other governmental body, including the Federal Communications
     Commission, ITC, OFTEL or DTI (except such as may be required under the
     securities or Blue Sky laws of the various states and those consents,
     authorizations, approvals, orders, filings, registrations or notices that
     have been obtained or made and are in full force and effect) and will not
     conflict with or constitute a breach of any of the terms or provisions of,
     or a default under, the certificate of incorporation or by-laws (or other
     governing documents) of the Company or any of its subsidiaries or any bond,
     debenture, note or any other evidence of indebtedness or in any indenture,
     material agreement or material instrument to which the Company or any of
     its Material Subsidiaries 

                                       4
<PAGE>
 
     is a party or by which it or any of its Material Subsidiaries is bound or
     any of their respective properties is subject, or violate or conflict with
     any law, statute, rule, regulation, judgment or court decree applicable to
     the Company or any of its Material Subsidiaries or any of their respective
     properties (including any laws, statutes, rules or regulations promulgated
     by ITC, OFTEL or DTI).

          (m)  Except as otherwise set forth in the Preliminary Offering
     Memorandum and the Final Offering Memorandum, there are no material
     investigations, proceedings or actions, whether judicial or administrative
     and whether brought by any regulatory body, administrative agency or other
     governmental body or by any other person, pending, or, to the knowledge of
     the Company, threatened, to which the Company or any of its Material
     Subsidiaries is a party or of which any of their respective properties is
     the subject.

          (n)  The Company and each of its Material Subsidiaries have all such
     permits, licenses, franchises and authorizations of governmental or
     regulatory authorities or other rights currently necessary to be procured
     by them in order to engage in the respective businesses currently conducted
     by each of them as set forth in the Preliminary Offering Memorandum and the
     Final Offering Memorandum (collectively, "Permits"), including, without
                                               -------                      
     limitation, under any laws regulating or relating to the conduct of
     cable/telephony operations, as are necessary to own, lease and operate its
     respective properties and to conduct its business, except where the failure
     to have any such Permit would not have a material adverse effect on the
     business, financial condition or results of operations of the Company and
     its subsidiaries taken as a whole; the Company and each of its Material
     Subsidiaries have fulfilled and performed all of their respective
     obligations with respect to such Permits, and no event has occurred that
     allows, or after notice or lapse of time would allow, revocation or
     termination of any such Permit or result in any other impairment of the
     rights of the holder of any such Permit, except in each case, as would not
     have a material adverse effect on the business, financial condition or
     results of operations of the Company and its subsidiaries taken as a whole,
     and subject in each case to such qualification as may be set forth in the
     Preliminary Offering Memorandum and the Final Offering Memorandum; and,
     except as described in the Preliminary Offering Memorandum and the Final
     Offering Memorandum, no such Permit contains any restriction that would
     have a material adverse effect on the business, financial condition or
     results of operations of the Company and its subsidiaries taken as a whole.
     Neither the Company nor any of its Material Subsidiaries has any reason to
     believe that any governmental body or regulatory agency is considering
     limiting, suspending or revoking any Permits, except as would not have a
     material adverse effect on the business, financial condition or results of
     operations of the Company and its subsidiaries taken as a whole.

          (o)  This Agreement has been duly and validly authorized, executed and
     delivered by the Company.

          (p)  The Sterling Senior Notes Indenture has been duly and validly
     authorized by the Company and, when duly executed and delivered by the
     Company and duly authorized, executed and delivered by the Sterling Senior
     Notes Trustee, will be the valid and legally binding obligation of the
     Company, enforceable against the Company in accordance with its terms,
     except to the extent that (i) enforcement thereof may be limited by (1)
     bankruptcy, insolvency, reorganization, moratorium or other similar laws
     now or hereafter in effect relating to or affecting creditors' rights

          5.  Agreements. The Company agrees with each Initial Purchaser that:
              ----------

          (b)  At any time prior to the completion of the sale of the Securities
     by the Initial Purchasers, the Company will not amend or supplement the
     Final Offering Memorandum if the Initial Purchasers reasonably object to
     such amendment or supplement within two business days after receiving a
     copy thereof, and if at any time prior to the completion of the sale of the
     Securities by the Initial Purchasers, any event occurs as a result of which
     the Final Offering Memorandum, as then amended or supplemented, would
     include any untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, or if it should
     be necessary to amend or supplement the Final Offering 

                                       12
<PAGE>
 
     Memorandum to comply with applicable law, the Company will promptly notify
     the Initial Purchasers of the same, will prepare and provide to the Initial
     Purchasers the proposed amendment or supplement which will correct such
     statement or omission or effect such compliance and will not publish such
     amendment or supplement if the Initial Purchasers reasonably object to the
     publication of such amendment or supplement within two business days after
     receiving a copy thereof.

          (c)  The Company will arrange for the qualification of the Securities
     for sale by the Initial Purchasers under the laws of such jurisdictions, if
     any, as the Initial Purchasers may reasonably designate in writing prior to
     the date of this Agreement and will maintain such qualifications in effect
     so long as reasonably required for the distribution of the Securities;
     provided, however, that the Company shall not be required in connection

     therewith to qualify to do business in any jurisdiction where it is not now
     so qualified or to take any action which would subject it to general or
     unlimited service of process or taxation in any jurisdiction where it is
     not now so subject. The Company will promptly advise the Initial Purchasers
     of the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the initiation or threatening of any proceeding for such
     purpose.

     to, resell any Securities that have been acquired by any of them.

          (e)  Neither the Company, nor any of its Affiliates, nor any person
     acting on its or their behalf will, directly or indirectly, make offers or

     the Securities Act.

     acting on its or their behalf will engage in any form of general
     solicitation or general advertising (within the meaning of Regulation D) in
     connection with any offer or sale of the Securities in the United States,
     except pursuant to a registered public offering as provided in the
     Registration Rights Agreements.

          (g)  So long as any of the Securities are "restricted securities"
     within the meaning of Rule 144(a)(3) under the Securities Act, the Company
     will, during any period in which it is not subject to and in compliance
     with Section 13 or 15(d) of the Exchange Act, provide to each holder of
     such restricted securities and to each prospective purchaser (as designated
     by such holder) of such restricted securities, upon the request of such
     holder or prospective purchaser, any information required to be provided by
     Rule 144A(d)(4) under the Securities Act. This covenant is intended to be
     for the benefit of the holders, and the prospective purchasers designated

          legal or governmental proceedings pending or threatened to which the
          Company or any of its subsidiaries is or could be a party or to which
          any of their respective property is or could be subject, which might
          result in a material adverse effect on the business, financial

          initially resell the Securities receive a copy of the Final Offering
          Memorandum prior to such sale, the offer, sale and initial resale of

          Final Offering Memorandum, do not require registration under the
          Securities Act and the Indentures do not require qualification under
          the Trust Indenture Act, it being understood that such counsel does
          not express any opinion as to any subsequent resale of any Security;
          and

          Such counsel shall also state that, in the course of preparation by
the Company of the Final Offering Memorandum, such counsel has participated in
conferences with directors, officers and other representatives of the Company,
representatives of the independent public accountants for the Company,
representatives of the Initial Purchasers and representatives of Counsel for the
Initial Purchasers, at which conferences the contents of the Final Offering
Memorandum and related matters were discussed and, although such counsel is not
passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Final Offering
Memorandum and has made no independent check or verification thereof (except as
stated in paragraph (xi) hereof), on the basis of the foregoing (relying as to
materiality to a large extent upon the statements of directors, officers and
other representatives of the Company), no facts have come to such counsel's
attention which have caused such counsel to believe that the Final Offering
Memorandum, as of its date or as of the Closing Date, contained or contains an
untrue statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading (it being understood
that such counsel need not express any opinion or belief with respect to the
financial statements and schedules and other financial, statistical and
accounting data included in or excluded from the Final Offering Memorandum).

          Such opinion may be limited to the General Corporation Law of the
State of Delaware and the laws of the State of New York and the federal laws of
the United States and may be subject to customary assumptions, qualifications
and exceptions. In rendering such opinion, such counsel may rely as to matters
involving the application of laws of any jurisdiction other than the State of
New York, the State of Delaware or the United States, to the extent such counsel
deems proper and specified in such opinion, upon the opinion of other counsel
who are satisfactory to Counsel for the Initial Purchasers.

          All references in this Section 6(a) to the Final Offering Memorandum
shall be deemed to include any amendment or supplement thereto at the Closing
Date.

          of the Initial Purchasers' representations and warranties set forth in
          Section 4 of this Agreement, (2) the due performance by the Company of
          the agreements set forth in Section 5 of this Agreement and the due
          performance by the Initial Purchasers of the agreements set forth in

          initially resell the Securities receive a copy of the Final Offering
          Memorandum prior to such sale, the offer, sale and initial resale of
          the Securities in the manner contemplated by this Agreement and the
          Final Offering Memorandum, do not require registration under the
          Securities Act and the Indentures do not require qualification under
          the Trust Indenture, it being understood that such counsel does not
          express any opinion as to any subsequent resale of any Security.

          Such counsel shall also state that, in the course of preparation by
the Company of the Final Offering Memorandum, such counsel has participated in
conferences with directors, officers and other representatives of the Company,
representatives of the independent public accountants for the Company,
representatives of the Initial Purchasers and representatives of Counsel for the
Initial Purchasers, at which conferences the contents of the Final Offering
Memorandum and related matters were discussed and, although such counsel is not
passing upon, and does not assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Final Offering
Memorandum and has made no independent check or verification thereof (except to
the extent stated in paragraphs (ix) and (xi) hereof), on the basis of the
foregoing, no facts have come to such counsel's attention which have caused such
counsel to believe that the Final Offering Memorandum, as of its date and as of
the Closing Date, contained or contains an untrue statement of a material fact
or omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading (it being understood that such counsel need not express any
opinion or belief with respect to the financial statements and schedules and
other financial, statistical and accounting data included in the Final Offering
Memorandum).

          Such opinion may be limited to the General Corporation Law of the
State of Delaware and the laws of the State of New York and the federal laws of
the United States and may be subject to customary assumptions, qualifications
and exceptions. In rendering such opinion, such counsel may rely as to matters
involving the application of laws of any jurisdiction other than the State of
New York, the State of Delaware or the United States, to the extent they deem
proper and specified in such opinion, upon the opinion of other counsel who are
satisfactory to Counsel for the Initial Purchasers.

     Closing Date, with respect to the issuance and sale of the Securities, the
     Final Offering Memorandum (as amended or supplemented at the Closing Date)
     and other related matters as the Initial Purchasers may reasonably require,

     request for the purpose of enabling them to pass upon such matters.

          (e)  The Company shall have furnished to the Initial Purchasers a
     certificate of the Company, signed by the Chairman of the Board or the

          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date,

          the Company and its subsidiaries taken as a whole whether or not
          arising from transactions in the ordinary course of business, except
          as set forth in or contemplated by the Final Offering Memorandum
          (exclusive of any amendment or supplement thereto); and

          the shareholders and the Board of Directors and other committees of
          the Company and its subsidiaries as set forth in the minute books
          through a specified date not more than five business days prior to the
          date of the letter, and have inquired of certain officials of the
          Company who have responsibility for financial and accounting matters;

                  (iii)  with respect to the nine-month periods ended September
          30, 1996 and 1997, (X) they have (1) performed the procedures
          specified by the American Institute of Certified Public Accountants
          for review of interim financial information as described in SAS No.
          71, "Interim Financial Information", on the unaudited condensed
          consolidated financial statements of the Company and its subsidiaries
          (the "Unaudited Financials") included in the Final Offering Memorandum
                --------------------                                            
          and (2) inquired of certain officials of the Company who have
          responsibility for financial and accounting matters whether the
          Unaudited Financials are stated on a basis substantially consistent
          with that of the audited consolidated financial statements of the
          Company and its subsidiaries included in the Final Offering Memorandum
          and (Y) as a result of the procedures performed in (X) above, nothing
          came to their attention that caused them to believe that any material
          modifications should be made to such Unaudited Financials for them to
          be in conformity with generally accepted accounting principles;

                  (iv)  with respect to the period subsequent to September 30,
          1997, management of the Company has informed them that there were not
          any changes at a specified date not more than five business days prior

          its subsidiaries or decreases in the capital stock of the Company as
          compared with the amounts shown on the September 30, 1997,

          condensed consolidated balance sheet referred to above, except in all
          instances for changes, decreases or increases set forth in such
          letter, in which case the letter shall be accompanied by an
          explanation by the Company as to the significance thereof unless said
          explanation is not deemed necessary by the Initial Purchasers; and

                  (v)  they have performed certain other specified procedures as
          a result of which they determined that certain information of
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Final Offering Memorandum, including certain information
          set forth under the captions "Offering Memorandum Summary"; "Summary
          Historical Consolidated Financial Information"; "Risk Factors";

     which information is given in the Final Offering Memorandum, there shall
     not have been (i) any change or decrease specified in the letter or letters
     referred to in paragraph (f) of this Section 6 or (ii) any change, or any
     development involving a prospective change, in or affecting the condition,
     financial or otherwise, or in the earnings, business or operations of the
     Company and its subsidiaries the effect of which is, in the judgment of the
     Initial Purchasers, so material and adverse as to make it impractical or
     inadvisable to market the Securities as contemplated by the Final Offering
     Memorandum.

          (h)  Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Securities Act).

          (i)  Prior to the Closing Date, the Company shall have furnished to
     the Initial Purchasers such further information, certificates and documents
     as the Initial Purchasers may reasonably request.

          (j)  On or prior to the Closing Date, each of the Indentures and the
     Registration Rights Agreements shall have been executed substantially in
     the form hereto delivered to you and shall have been delivered to you and
     the applicable Trustee.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Initial Purchasers and Counsel for the Initial Purchasers,

              -------------------------                                        
for herein is not consummated because any condition to the obligations of the
Initial Purchasers set forth in Section 6 hereof is not satisfied, because of
any termination pursuant to Section 10 hereof or because of any refusal,
inability or failure on the part of the Company to perform any agreement herein
or comply with any provision hereof other than by reason of a default by any of
the Initial Purchasers in payment for the Securities on the Closing Date, the
Company will reimburse the Initial Purchasers severally upon demand for all
reasonable out-of-pocket expenses (including reasonable fees and disbursements
of counsel) that shall have been incurred by them in connection with the
proposed purchase and sale of the Securities against appropriate receipts there
for.

          8.  Indemnification and Contribution. (a)  The Company agrees to 
              -------------------------------- 
indemnify and hold harmless each Initial Purchaser, each person who controls any
Initial Purchaser within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act and the respective officers, directors,
partners, employees, representatives and agents of such Initial Purchaser or
controlling person thereof against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Securities Act, the Exchange Act or other Federal or state statutory
law or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Preliminary Offering Memorandum, the Final Offering Memorandum,
or in any amendment thereof or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
                                                             --------  -------
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made in
the Preliminary Offering Memorandum, the Final Offering Memorandum or any
information provided by the Company to any holder or prospective purchaser of
Securities pursuant to paragraph 5(g) hereof, or in any amendment thereof or
supplement thereto, in reliance upon and in conformity with written information
relating to any Initial Purchaser furnished to the Company by or on behalf of
any Initial Purchaser specifically for inclusion therein; provided, further,
that the foregoing indemnity agreement with respect to any Preliminary Offering
Memorandum shall not inure to the benefit of any Initial Purchaser who failed to
deliver a Final Offering Memorandum (as so amended or supplemented, provided by
the

                                       28
<PAGE>
 
Company to the several Initial Purchasers in the requisite quantity and on a
timely basis to permit proper delivery on or prior to the written confirmation
of the sale of Securities by such Initial Purchaser to the relevant person) to
the person asserting any losses, claims, damages and liabilities and judgements
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Offering Memorandum, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, if such material
misstatement or omission or alleged material misstatement or omission was cured
in the Final Offering Memorandum. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

          (b)  Each Initial Purchaser, severally and not jointly, agrees to
indemnify and hold harmless the Company, its directors, its officers, and each
person who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Initial Purchaser, but only with
reference to written information relating to such Initial Purchaser furnished to
the Company by or on behalf of such Initial Purchaser specifically for inclusion
in the Preliminary Offering Memorandum or the Final Offering Memorandum (or in
any amendment or supplement thereto). This indemnity agreement will be in
addition to any liability which any Initial Purchaser may otherwise have. The
Company acknowledges that the statements relating to the Initial Purchasers set
forth in the last paragraph of the cover page and in the first sentence, the
second sentence and the fourth sentence of the third paragraph, the fifth
paragraph, the second sentence of the eighth paragraph and the ninth paragraph
under the heading "Plan of Distribution" in the Preliminary Offering Memorandum
and the last paragraph of the cover page and in the first sentence, the second
sentence and the fourth sentence of the fourth paragraph, the eighth paragraph,
the second sentence of the eleventh paragraph and the twelfth paragraph under
the heading "Plan of Distribution" in the Final Offering Memorandum constitute
the only information furnished in writing by or on behalf of the Initial
Purchasers for inclusion in the Preliminary Offering Memorandum or the Final
Offering Memorandum (or in any amendment or supplement thereto).

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action (including any governmental
investigation), such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 8, notify the
indemnifying party in writing of the commencement thereof; but the failure so to
notify the indemnifying party (i) will not relieve it from liability under
paragraph (a) or (b) above unless and to the extent it did not otherwise learn
of such action and such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
                            --------  -------                            
reasonably satisfactory to the indemnified party. Notwithstanding the

                                       29
<PAGE>
 
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i) the
indemnifying party shall authorize the indemnified party in writing to employ
separate counsel at the expense of the indemnifying party, (ii) the use of
counsel chosen by the indemnifying party to represent the indemnified party
would present such counsel with a conflict of interest, (iii) the indemnifying
party shall not have employed counsel reasonably satisfactory to the indemnified
party to represent the indemnified party within a reasonable time after notice
of the institution of such action or (iv) the named parties of any such action
(including any impleaded parties) include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
based upon the advice of such counsel (with a copy to the indemnifying party)
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party (in any of which cases the indemnifying party shall not have
the right to assume the defense of such action on behalf of such indemnified
party, it being understood, however, that the indemnifying party shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (in addition to any local counsel) for all such
indemnified parties, which firm shall be designated in writing by the
indemnified party, and that all such reasonable fees and expenses shall be
reimbursed as they are incurred upon written request and presentation of
satisfactory invoices).  The indemnifying party shall indemnify and hold
harmless the indemnified party from and against all losses, claims, damages and
liabilities by reason of any settlement of any action (i) effected with its
written consent or (ii) effected without its written consent if the settlement
is entered into more than twenty business days after the indemnifying party
shall have received a request from the indemnified party for reimbursement for
the fees and expenses of counsel (in any case where such fees and expenses are
at the expense of the indemnifying party) and, prior to the date of such
settlement, the indemnifying party shall have failed to comply with such
reimbursement request.  Notwithstanding the immediately preceding sentence, if
at any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, an
indemnifying party shall not be liable for any settlement of the nature
contemplated by the immediately preceding sentence effected without its consent
if such indemnifying party (i) reimburses such indemnified party in accordance
with such request to the extent that it considers such request to be reasonable
and (ii) provides written notice to the indemnified party substantiating the
unpaid balance as unreasonable, in each case, prior to the date of settlement.
An indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
(i) includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act, by or on behalf of the indemnified party.

                                       30
<PAGE>
 
          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Initial Purchasers agree
to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
                                                ------                       
and one or more of the Initial Purchasers may be subject in such proportion as
is appropriate to reflect the relative benefits received by the Company and by
the Initial Purchasers from the offering of the Securities; provided, however,
                                                            --------  ------- 
that in no case shall any Initial Purchaser (except as may be provided in any
agreement among the Initial Purchasers relating to the offering of the
Securities) be responsible for any amount in excess of the purchase discount or
commission applicable to the Securities purchased by such Initial Purchaser
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Initial Purchasers shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company and of the Initial
Purchasers in connection with the statements or omissions which resulted in such
Losses as well as any other relevant equitable considerations. Benefits received
by the Company shall be deemed to be equal to the total net proceeds from the
offering (before deducting expenses), and benefits received by the Initial
Purchasers shall be deemed to be equal to the total purchase discounts and
commissions received by the Initial Purchasers from the Company in connection
with the purchase of the Securities hereunder. Relative fault shall be
determined by reference to whether any alleged untrue statement or omission
relates to information provided by the Company or the Initial Purchasers. The
Initial Purchasers' respective obligations to contribute to this Section 8 are
several in proportion to the respective principal amount of Securities they have
purchased hereunder, and not joint. The Company and the Initial Purchasers agree
that it would not be just and equitable if contribution were determined by pro
rata allocation or any other method of allocation which does not take account of
the equitable considerations referred to above. Notwithstanding the provisions
of this paragraph (d), no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 8, each person who controls an
Initial Purchaser within the meaning of either the Securities Act or the
Exchange Act and each director, officer, employee and agent of an Initial
Purchaser shall have the same rights to contribution as such Initial Purchaser,
and each person who controls the Company within the meaning of either the
Securities Act or the Exchange Act and each officer, director, employee and
agent of the Company shall have the same rights to contribution as the Company,
subject in each case to the applicable terms and conditions of this paragraph
(d).

          9.  Default by an Initial Purchaser. If any one or more Initial
              -------------------------------                            
Purchasers shall fail to purchase and pay for any of the Securities agreed to be
purchased by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of the
Senior Notes, the Sterling Deferred Coupon Notes or the USD Deferred Coupon
Notes, as applicable, set forth opposite their names in Schedule I or Schedule
II, as the case may be, bears to the aggregate principal amount of such
Securities set forth opposite the names of all the remaining Initial 

                                       31
<PAGE>
 
Purchasers in Schedule I or Schedule II, as the case may be) the Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed
to purchase; provided, however, that in the event that the aggregate principal
             --------  -------                                                
amount of such Securities which the defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase shall exceed 10% of the aggregate
principal amount of such Securities set forth in Schedule I or Schedule II, as
the case may be, the remaining Initial Purchasers that agreed to purchase such
Securities shall have the right to purchase all, but shall not be under any
obligation to purchase any, of such Securities, and if such non-defaulting
Initial Purchasers do not purchase all such Securities, this Agreement will
terminate without liability to any non-defaulting Initial Purchaser or the
Company. In the event of a default by any Initial Purchaser as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
seven days, as the non-defaulting Initial Purchasers shall determine in order
that the required changes in the Final Offering Memorandum or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting Initial Purchaser of its liability, if any, to the
Company or any non-defaulting Initial Purchaser for damages occasioned by its
default hereunder.

          10.  Termination. This Agreement shall be subject to termination in
               -----------

Company prior to delivery of and payment for the Securities, if prior to such
time (i) trading in any of the Company's securities shall have been suspended by
the Commission or by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") or trading in securities generally on the New York

Stock Exchange, the Luxembourg Stock Exchange or NASDAQ shall have been
materially suspended or materially limited (except such limitations on such
trading in effect as of the Execution Time) or minimum prices shall have been
established on either such exchange or NASDAQ, (ii) a banking moratorium shall
have been declared either by Federal or New York State authorities or (iii)
there shall have occurred any outbreak or escalation of hostilities, declaration
by the United States of a national emergency or war or other calamity or crisis
the effect of which on financial markets are such as to make it, in the judgment
of the Initial Purchasers, impracticable or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Final Offering
Memorandum.

Old Sterling Senior Notes and the Old Sterling Deferred Coupon Notes, the "Old
Notes" and together with the New Notes, the "Notes") of the Company from the
holders thereof. Capitalized terms used but not defined herein have the
meanings given to them in the Prospectus.
 
  For each Old Note accepted for exchange and not validly withdrawn, the holder
of such Old Note will receive a New Note having (i) in the case of New Sterling
Senior Notes, a principal amount equal to that of the surrendered Old Sterling
Senior Notes, or (ii) in the case of New Sterling Deferred Coupon Notes or New
USD Deferred Coupon Notes, a principal amount at maturity equal to the
surrendered Old Sterling Deferred Coupon Notes or Old USD Deferred Coupon
Notes, as applicable. If the Exchange Offer is not consummated by January 17,
1999, interest will accrue (in addition to the stated interest on the Old
Sterling Senior Notes and in addition to the accrual of the original issue
discount and stated interest on the Old Sterling Deferred Coupon Notes and the
Old USD Deferred Coupon Notes) from and including January 18, 1999. Such
additional interest (the "Special Interest"), if any, will be payable in cash
semiannually in arrears each April 1 and October 1, to holders of record on the
immediately preceding March 15 and September 15, respectively, at a rate per
annum equal to 0.50% of the principal amount of the Old Sterling Senior Notes
or the Accreted Value of the Old Sterling Deferred Coupon Notes or Old USD
Deferred Coupon Notes, as the case may be (determined daily). The aggregate
amount of Special Interest payable pursuant to the above provisions will in no
event exceed 1.50% per annum of the principal amount of the Old Sterling Senior
Notes or the Accreted Value of the Old Sterling Deferred Coupon Notes or Old
USD Deferred Coupon Notes, as the case may be (determined daily). Upon the
consummation of the Exchange Offer after January 17, 1999, the Special Interest
payable on the Old Notes from the date of such consummation will cease to
accrue. Following the consummation of the Exchange Offer, the interest terms
shall revert to the original terms set forth in the Notes. Except as otherwise
provided in the Prospectus, Holders of Old Notes accepted for exchange will be
deemed to have waived the right to receive any other payments or accrued
interest, if any, on the Old Notes. The Company reserves the right, at any time
or from time to time, to extend the Exchange Offer at its discretion, in which
event the term "Expiration Date" shall mean the latest time and date to which
the Exchange Offer is extended. The Company shall notify the holders of the Old
Notes of any extension by means of a press release or other public announcement
prior to 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date.
 
  This Letter is to be completed by a holder of Old Notes either if
certificates for such Old Notes are to be forwarded herewith or if a tender is
to be made by book-entry transfer to the account maintained by the Exchange
Agent at The Depository Trust Company (the "Book-Entry Transfer Facility")
pursuant to the procedures set forth in the Prospectus under "The Exchange
Offer--Book-Entry Transfer" and an Agent's Message is not delivered. Tenders by
book-entry transfer may also be made by delivering an Agent's Message in lieu
of this Letter. The term "Agent's Message" means a message, transmitted by the
Book-Entry Transfer Facility to and received by the Exchange Agent and forming
a part of a Book-Entry Confirmation (as defined below), which states that the
Book-Entry Transfer Facility has received an express acknowledgment from the
tendering Participant, which acknowledgment states that such Participant has
received and agrees to be bound by, and makes each of the representations and
warranties contained in, this Letter and that the Company may enforce this
Letter against such Participant. Holders of Old Notes whose certificates are
not immediately available, or who are unable to deliver their certificates or
confirmation of the book-entry tender of their Old Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility (a "Book-Entry
Confirmation") and all other documents required by this Letter to the Exchange
Agent on or prior to the Expiration Date, must tender their Old Notes according
to the guaranteed delivery procedures set forth in the Prospectus under "The
Exchange Offer--Guaranteed Delivery Procedures." See Instruction 1. Delivery of
documents to the Book-Entry Transfer Facility does not constitute delivery to
the Exchange Agent.

Ladies and Gentlemen:
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount at
maturity of Old Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby
sells, assigns and transfers to, or upon the order of, the Company all right,
title and interest in and to such Old Notes as are being tendered hereby.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Old Notes tendered
hereby and that the Company will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim when the same are accepted by the Company. The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent its
agent and attorney-in-fact with full power of substitution, for purposes of
delivering this Letter and the Old Notes to the Company. The Power of Attorney
granted in this paragraph shall be deemed irrevocable from and after the
Expiration Date and coupled with an interest. The undersigned hereby further
represents that any New Notes acquired in exchange for Old Notes tendered hereby
will have been acquired in the ordinary course of business of the person
receiving such New Notes, whether or not such person is the undersigned, that
neither the holder of such Old Notes nor any such other person is engaged in, or
intends to engage in, or has an arrangement or understanding with any person to
participate in, the distribution (within the meaning of the Securities Act of
1933, as amended (the "Securities Act")) of such New Notes and that neither the
holder of such Old Notes nor any such other person is an "affiliate," as defined
in Rule 405 under the Securities Act, of the Company.
 
  The undersigned also acknowledges that this Exchange Offer is being made by
the Company in reliance on an interpretation by the staff of the Securities and
Exchange Commission (the "SEC"), as set forth in no-action letters issued to
third parties, that the New Notes issued in exchange for the Old Notes pursuant
to the Exchange Offer may be offered for resale, resold and otherwise
transferred by holders thereof (other than any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such holders' business and such holders have no
arrangement with any person to participate in the distribution (within the
meaning of the Securities Act) of such New Notes. If the undersigned is not a
broker-dealer, the undersigned represents that it is not engaged in, and does
not intend to engage in, and has no arrangement or understanding with any person
to participate in, a distribution (within the meaning of the Securities Act) of
New Notes. If the undersigned is a broker-dealer that will receive New Notes for
its own account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading activities, it acknowledges that it
will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Notes; however, by so acknowledging and
by delivering a prospectus, the undersigned will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. The undersigned
acknowledges that in reliance on an interpretation by the staff of the SEC, a
broker-dealer may fulfill his prospectus delivery requirements with respect to
the New Notes (other than a resale of an unsold allotment from the original sale
of the Old Notes) with the Prospectus which constitutes part of this Exchange
Offer.
 
  The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder
<PAGE>
 
shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and legal representatives of the
undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. The tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer--Withdrawal Rights"
section of the Prospectus.
 
  Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please issue the New Notes (and, if applicable, substitute
certificates representing Old Notes for any Old Notes not exchanged) in the
name of the undersigned or, in the case of a book-entry delivery of Old Notes,
please credit the account indicated above maintained at the Book-Entry Transfer
Facility. Similarly, unless otherwise indicated under the box entitled "Special
Delivery Instructions" below, please send the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not exchanged)
to the undersigned at the address shown above in the box entitled "Description
of Old Notes."

1. DELIVERY OF THIS LETTER AND NOTES; GUARANTEED DELIVERY PROCEDURES.
 
  This Letter is to be completed by holders (which term, for purposes of the
Exchange Offer, includes any participant in the Book-Entry Transfer Facility
system whose name appears on a security position listing as the holder of such
Old Notes) either if certificates are to be forwarded herewith or if tenders
are to be made pursuant to the procedures for delivery by book-entry transfer
set forth in the Prospectus under "The Exchange Offer--Book-Entry Transfer"
and an Agent's Message is not delivered. Tenders by book-entry transfer may
also be made by delivering an Agent's Message in lieu of this Letter. The term
"Agent's Message" means a message, transmitted by the Book-Entry Transfer
Facility to and received by the Exchange Agent and forming a part of a Book-
Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the tendering Participant, which
acknowledgment states that such Participant has received and agrees to be
bound by, and makes the representations and warranties contained in, this
Letter and that the Company may enforce this Letter against such Participant.
Certificates for all physically tendered Old Notes, or Book-Entry
Confirmation, as the case may be, as well as a properly completed and duly
executed Letter (or facsimile hereof or Agent's Message in lieu thereof) and
any other documents required by this Letter, must be received by the Exchange
Agent at the address set forth herein on or prior to the Expiration Date, or
the tendering holder must comply with the guaranteed delivery procedures set
forth below. Old Notes tendered hereby must be in denominations of principal
amount at maturity of $1,000 or (Pounds)1,000 and any integral multiple
thereof.
 
  Holders whose certificates for Old Notes are not immediately available or
who cannot deliver their certificates and all other required documents to the
Exchange Agent on or prior to the Expiration Date, or who cannot complete the
procedure for book-entry transfer on a timely basis, may tender their Old
Notes pursuant to the guaranteed delivery procedures set forth in the
Prospectus under "The Exchange Offer--Guaranteed Delivery Procedures."
Pursuant to such procedures, (i) such tender must be made through an Eligible
Institution, (ii) prior to the Expiration Date, the Exchange Agent must
receive from such Eligible Institution a properly completed and duly executed
Notice of Guaranteed Delivery, substantially in the form provided by the
Company (by telegram, telex, facsimile transmission, mail or hand delivery),
setting forth the name and address of the holder of Old Notes and the amount
of Old Notes tendered, stating that the tender is being made thereby and
guaranteeing that within five New York Stock Exchange ("NYSE") trading days
after the date of execution of the Notice of Guaranteed Delivery, the
certificates for all physically tendered Old Notes, or a Book-Entry
Confirmation, together with a properly completed and duly executed Letter (or
facsimile thereof or Agent's Message in lieu thereof) with any required
signature guarantees and any other documents required by the Letter will be
deposited by the Eligible Institution with the Exchange Agent, and (iii) the
certificates for all physically tendered Old Notes, in the proper form for
transfer, or Book-Entry Confirmation, as the case may be, together with a
properly completed and duly executed Letter (or facsimile thereof or Agent's
Message in lieu thereof) with any required signature guarantees and all other
documents required by this Letter, are received by the Exchange Agent within
five NYSE trading days after the date of execution of the Notice of Guaranteed
Delivery.
 
  The method of delivery of this Letter, the Old Notes and all other required
documents is at the election and risk of the tendering holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If Old Notes are sent by mail, it is suggested that the
mailing be made sufficiently in
<PAGE>
 
advance of the Expiration Date to permit delivery to the Exchange Agent prior
to 5:00 p.m., New York City time, on the Expiration Date.
 
  See the Prospectus under "The Exchange Offer."
 
2. PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).
 
  If less than all of the Old Notes evidenced by a submitted certificate are
to be tendered, the tendering holder(s) should fill in the aggregate principal
amount of Old Notes to be tendered in the box above entitled "Description of
Old Notes--Principal Amount Tendered." A reissued certificate representing the
balance of nontendered Old Notes will be sent to such tendering holder, unless
otherwise provided in the appropriate box on this letter, promptly after the
Expiration Date. ALL OF THE OLD NOTES DELIVERED TO THE EXCHANGE AGENT WILL BE
DEEMED TO HAVE BEEN TENDERED UNLESS OTHERWISE INDICATED.
 
3. SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
SIGNATURES.
 
  If this Letter is signed by the Holder of the Old Notes tendered hereby, the
signature must correspond exactly with the name as written on the face of the
certificates or on the Book-Entry Transfer Facility's security position
listing as the holder of such Old Notes without any change whatsoever.
 
  If any tendered Old Notes are owned of record by two or more joint owners,
all of such owners must sign this Letter.
 
  If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate copies of this Letter as there are different registrations of
certificates.
 
  When this Letter is signed by the registered holder or holders of the Old
Notes specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If, however, the New Notes are to be
issued, or any untendered Old Notes are to be reissued, to a person other than
the registered holder, then endorsements of any certificates transmitted
hereby or separate bond powers are required. Signatures on such certificate(s)
or bond powers must be guaranteed by a participant in a securities transfer
association recognized signature program.
 
  If this Letter is signed by a person other than the registered holder or
holders of any certificate(s) specified herein, such certificate(s) must be
endorsed or accompanied by appropriate bond powers, in either case signed
exactly as the name or names of the registered holder or holders appear(s) on
the certificate(s) and signatures on such certificate(s) or bond powers must
be guaranteed by an Eligible Institution.
 
  If this Letter or any certificates or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must

REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS A MEMBER
OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE NATIONAL
ASSOCIATION OF SECURITIES DEALERS, INC. OR BY A COMMERCIAL BANK OR TRUST
COMPANY HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES (AN "ELIGIBLE
INSTITUTION").
 
  SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE INSTITUTION,
PROVIDED THE OLD NOTES ARE TENDERED: (I) BY A REGISTERED HOLDER OF OLD NOTES
WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL ISSUANCE INSTRUCTIONS" OR
"SPECIAL DELIVERY INSTRUCTIONS" ON THIS LETTER OR (II) FOR THE ACCOUNT OF AN
ELIGIBLE INSTITUTION.
 
4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTION.
 
  Tendering holders of Old Notes should indicate in the applicable box the
name and address to which New Notes issued pursuant to the Exchange Offer
and/or substitute certificates evidencing Old Notes not exchanged are to be
issued or sent, if different from the name or address of the person signing
this Letter. In the case of issuance in a different name, the employer
identification or social security number of the person named must
<PAGE>
 
also be indicated. Holders tendering Old Notes by book-entry transfer may
request that Old Notes not exchanged be credited to such account maintained at
the Book-Entry Transfer Facility as such holder may designate hereon. If no
such instructions are given, such Old Notes not exchanged will be returned to
the name or address of the person signing this Letter.
 
5. TAX IDENTIFICATION NUMBER.
 
  Federal income tax law generally requires that a tendering holder whose Old
Notes are accepted for exchange must provide the Company (as payor) with such
holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9
below, which in the case of a tendering holder who is an individual, is his or
her social security number. If the Company is not provided with the current
TIN or an adequate basis for an exemption, such tendering holder may be
subject to a $50 penalty imposed by the Internal Revenue Service. In addition,
delivery to such tendering holder of New Notes may be subject to backup
withholding in an amount equal to 31% of all reportable payments made after
the exchange. If withholding results in an overpayment for taxes, a refund may
be obtained.
 
  Exempt holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. See the enclosed Guidelines of Certification of
Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines")
for additional instructions.
 
  To prevent backup withholding, each tendering holder of Old Notes must
provide its correct TIN by completing the "Substitute Form W-9" set forth
below, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN) and that (i) the holder is exempt from backup withholding,
(ii) the holder has not been notified by the Internal Revenue Service that
such holder is subject to a backup withholding as a result of a failure to
report all interest or dividends or (iii) the Internal Revenue Service has
notified the holder that such holder is no longer subject to backup
withholding. If the tendering holder of Old Notes is a nonresident alien or
foreign entity not subject to backup withholding, such holder must give the
Company a completed Form W-8, Certificate of Foreign Status. These forms may
be obtained from the Exchange Agent. If the Old Notes are in more than one
name or are not in the name of the actual owner, such holder should consult
the W-9 Guidelines for information on which the TIN to report. If such holder
does not have a TIN, such holder should consult the W-9 Guidelines for
instructions on applying for a TIN, check the box in Part 2 of the Substitute
Form W-9 and write "applied for" in lieu of its TIN. Note: Checking this box
and writing "applied for" on the form means that such holder has already
applied for a TIN or that such holder intends to apply for one in the near
future. If such holder does not provide its TIN to the Company within 60 days,
backup withholding will begin and continue until such holder furnishes its TIN
to the Company.
 
6. TRANSFER TAXES.
 
  The Company will pay all transfer taxes, if any, applicable to the transfer
of Old Notes to it or its order pursuant to the Exchange Offer. If, however,
New Notes and/or substitute Old Notes not exchanged are to be delivered to, or
are to be registered or issued in the name of, any person other than the
registered holder of the Old Notes tendered hereby, or if tendered Old Notes
are registered in the name of any person other than the person signing this
Letter, or if a transfer tax is imposed for any reason other than the transfer
of Old Notes to the Company or its order pursuant to the Exchange Offer, the
amount of any such transfer taxes (whether imposed on the registered holder or
any other person) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted
herewith, the amount of such transfer taxes will be billed directly to such
tendering holder.
 
7. WAIVER OF CONDITIONS.
 
  The Company reserves the absolute right to waive satisfaction of any or all
conditions enumerated in the Prospectus.
 
8. NO CONDITIONAL TENDERS.
 
  No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Notes, by execution of this Letter or
an Agent's Message in lieu thereof, shall waive any right to receive notice of
the acceptance of their Old Notes for exchange.
<PAGE>
 
  Neither the Company, the Exchange Agent nor any other person is obligated to
give notice of any defect or irregularity with respect to any tender of Old
Notes nor shall any of them incur any liability for failure to give any such
notice.
 
9. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.
 
  Any holder whose Old Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the addresses indicated above for further
instructions.
 
10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.
 
  Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter, may be directed to the
Exchange Agent, at the addresses and telephone numbers indicated above.
