                                  in respect of

                           TELEWEST COMMUNICATIONS PLC
                         (Commission File No. 005-53921)

         This Amendment No. 1 to Statement on Schedule 13D amends Items 1
through 7, inclusive, of a statement on Schedule 13D filed by Liberty Media
Corporation as set forth below. All other information contained in such
statement remains correct.

ITEM 1.  SECURITY AND ISSUER

         Liberty Media Corporation, a Delaware corporation (the "Reporting
Person"), is filing this Statement on Schedule 13D (this "Statement") with
respect to ordinary shares, par value 10 pence per share (the "Ordinary
Shares"), and limited voting convertible ordinary shares, par value 10 pence per
share (the "Limited Voting Shares"), of Telewest Communications plc, a public
limited company incorporated under the laws of England and Wales (the "Issuer"
or "Telewest").

         Pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), this Statement also relates to the Ordinary Shares
issuable upon conversion of Limited Voting Shares. Each Limited Voting Share is
convertible into one Ordinary Share by the holder thereof only to the extent
such conversion does not result in a change in control of Telewest for purposes
of the indentures governing certain of Telewest's issued and outstanding
promissory notes. The Limited Voting Shares have the same rights as the Ordinary
Shares, except that the Limited Voting Shares do not confer the right to vote on
resolutions to appoint, re-appoint, elect or remove directors of Telewest.


ITEM 2.  IDENTITY AND BACKGROUND

         There has been no change to this Item except for the addition of the

future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

         The Reporting Person currently holds its interest in the Issuer's
Ordinary Shares and Limited Voting Shares for investment purposes. Neither the
Reporting Person nor, to the best of its knowledge, any of its executive
officers, directors or controlling persons, have any present plans or proposals
which relate to or would result in: (i) any acquisition by any person of
additional securities of the Issuer, or any disposition of securities of the
Issuer; (ii) any extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Issuer or any of its subsidiaries;
(iii) any sale or transfer of a material amount of assets of the Issuer or any
of its subsidiaries; (iv) any change in the present board of directors or

(vi) any other material change in the Issuer's business or corporate structure;

control of the Issuer by any person; (viii) causing a class of equity securities
of the Issuer to be delisted from a national securities exchange or to cease to
be authorized to be quoted in an inter-dealer quotation system of a registered
national securities association; (ix) a class of equity securities of the Issuer
becoming eligible for termination of registration pursuant to section 12(g)(4)
of the Exchange Act; or (x) any action similar to any of those enumerated above.

         Notwithstanding the foregoing, the Reporting Person may determine to
change its investment intent with respect to the Issuer at any time in the
future. In reaching any conclusion as to its future course of action, the
Reporting Person will take into consideration various factors, such as the
Issuer's business and prospects, other developments concerning the Issuer, other
business opportunities available to the Reporting Person, developments with
respect to the business of the Reporting Person, and general economic and stock
market conditions, including, but not limited to, the market price of the
Ordinary Shares and Limited Voting Shares. The Reporting Person reserves the
right, depending on other relevant factors, to acquire additional Ordinary
Shares and Limited Voting Shares of the Issuer in open market or privately
negotiated transactions, to dispose of all or a portion of its holdings of the
Ordinary Shares and Limited Voting Shares and to change its intention with
respect to any or all of the matters referred to in this Item 4.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         There has been no change in this Item except for the addition of the
following information:

         (a)-(b) The Reporting Person beneficially owns 39,945,721 Ordinary
Shares and 2,185,093 Limited Voting Shares of the Issuer through its indirect
subsidiary Liberty UK Holdings, Inc. and 463,438,961 Ordinary Shares as a result
of the 50 percent interest of its indirect subsidiary Liberty UK in TW Holdings.
MediaOne beneficially owns 581,034,184 Ordinary Shares and 57,312,938 Limited
Voting Shares indirectly through its 50 percent interest in TW Holdings and
through its wholly-owned subsidiaries. The Limited Voting Shares that are
beneficially owned by MediaOne




                                       6
<PAGE>   7




formerly were designated as Ordinary Shares, and were redesignated as Limited
Voting Shares in connection with the Telewest rights offering referred to in
paragraph (c) below.

         The Reporting Person has sole voting and dispositive power with respect
to 503,384,682 Ordinary Shares and 2,185,093 Limited Voting Shares and may be
deemed to have shared voting and dispositive power with MediaOne with respect to
1,084,418,866 Ordinary Shares and 59,498,031 Limited Voting Shares as a result
of the 1999 Relationship Agreement (as defined below) and the Operating
Agreement referred to in the original statement which is amended hereby.
MediaOne has sole voting and dispositive power with respect to 581,034,184
Ordinary Shares and 57,312,938 Limited Voting Shares and may be deemed to have
shared voting and dispositive power with the Reporting Person with respect to
1,084,418,866 Ordinary Shares and 59,498,031 Limited Voting Shares as a result
of the 1999 Relationship Agreement and the Operating Agreement. The filing of
this Amendment shall not be construed as an admission by the Reporting Person
that it is, for the purposes of Section 13(d) of the Exchange Act, the
beneficial owner of the Ordinary Shares or Limited Voting Shares that are
beneficially owned by MediaOne.

         Based on information provided by the Issuer, the 503,384,682 Ordinary
Shares of the Issuer that are beneficially owned by the Reporting Person
represent 22.1% of the 2,280,827,073 Ordinary Shares of the Issuer that were
outstanding on November 22, 1999 and the 2,185,093 Limited Voting Shares that
are beneficially owned by the Reporting Person represent 2.5% of the 62,507,747
Limited Voting Shares of the Issuer that were outstanding on that date.

         The Limited Voting Shares are subject to the same contractual
arrangements relating to voting and disposition as previously were reported with
respect to the Ordinary Shares.

         To the Reporting Person's knowledge, none of the Schedule 1 Persons or
Schedule 2 Persons has any interest in any securities of the Issuer as of the
date of the event requiring the filing of this Amendment.

         (c) On November 18, 1999 and November 22, 1999 Liberty UK Holdings,
Inc. acquired 39,945,721 Ordinary Shares and 2,185,093 Limited Voting Shares,
respectively, pursuant to the obligation of a subsidiary of the Reporting Person
entered into on October 4, 1999 to purchase such shares in a rights offering by
Telewest to its shareholders to fund the purchase by Telewest of the 50 percent
interest in certain U.K. cable franchises that it did not already own. Except as
described in this Item and Item 6, neither the Reporting Person nor, to the
knowledge of the Reporting Person, any of the Schedule 1 Persons or Schedule 2
Persons, has executed transactions in Ordinary Shares or Limited Voting Shares
of the Issuer during the past 60 days.

         (d) Except as described in Item 6, no person has the right to receive
or the power to direct the receipt of dividends from, or the proceeds from the
sale of, the Ordinary Shares or the Limited Voting Shares that are beneficially
owned by the Reporting Person.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE ISSUER

         There has been no change to this Item except for the addition of the
following information:

         Liberty Media International, Inc., formerly named Tele-Communications
International, Inc. ("Liberty International"), Liberty UK, MediaOne
International Holdings, Inc., UK Cable, Cable Partnership and Telewest entered
into The 1999 Amended and Restated Relationship Agreement (the "1999
Relationship Agreement") effective as of May 21, 1999. The 1999 Relationship
Agreement generally reflects the arrangements which were in place among
Telewest, Liberty International and MediaOne under the Amended and Restated
Relationship Agreement dated as of April 15, 1998, with amendments made to
reflect the fact that certain persons have ceased to be significant shareholders
of Telewest. The Relationship Agreement also was amended to exempt changes in
the control of the Reporting Person and AT&T Corp. from changes in control that
trigger the buy-sell provisions between Liberty International and MediaOne.

         The foregoing description of the 1999 Relationship Agreement is a
summary thereof and does not purport to be complete, and is qualified in its
entirety by the full text of the 1999 Relationship Agreement, which is included
as Exhibit 1 and incorporated by reference herein.

         Other than as described above, to the best knowledge of the Reporting
Person there are no contracts, arrangements, understandings or relationships
(legal or otherwise) among the persons named in Item 2 and between such persons
and any person with respect to any securities of Telewest, including, but not
limited to, transfer or voting of any securities, finder's fees, joint ventures,
loan or option arrangements, puts or calls, guarantees of profits, division of
profits or loss or the giving or withholding of proxies.

VOTING AGREEMENT AMONG LIBERTY GROUP AND MEDIAONE GROUP

undertake to one another that they shall exercise the voting rights attached to
the Ordinary Shares owned by them and shall cause the Directors nominated by
them to vote (subject to their fiduciary duties as Directors of the Company) in
all matters in such manner as shall be agreed upon by the Liberty Shareholders
and the MediaOne Shareholders provided that if the Liberty Shareholders or the
MediaOne Shareholders (or the directors nominated by them respectively) have a
conflict of interest in any matter, they shall abstain and the others may vote
on such matter as they deem appropriate.

7.2 If the Liberty Shareholders and the MediaOne Shareholders cannot agree on
any matter within a period of 10 days after the matter is first presented for
decision, the matter in dispute shall be referred to the Chief Executive
Officers of Liberty and the ultimate parent company of the MediaOne Shareholders

decision of such officers shall be final and binding. If those officers cannot
agree on any matter presented to them prior to the earlier of the date the vote
is to be taken or five days after the matter is first submitted to them, voting
shall occur in such manner that would be most likely to continue the status quo,
without materially increasing the Company's financial obligations or materially
deviating from its approved budget and business plan.

7.3 Clauses 7.1 and 7.2 shall cease to apply if after 31 December 1999 the
Liberty Group or the MediaOne Group so elect by notice given to the other
following the disposal by the other after 15 April 1998 of more than 43 million

appointees on the Board conduct themselves in such a way that:

7.4.1 the terms of this Agreement are implemented in full; and

in respect of the voting rights attached to the Ordinary Shares held by TW
Holdings) to vote in favour of the appointment of a person to the Board who is
an employee, partner or officer of, or has a material consultancy with, any
member of the Liberty Group or the MediaOne Group.

7.6 Subject to clause 7.8, if any transaction, arrangement or agreement (or
amendment thereto) to which the Telewest Group is a party or proposes to be a
party gives rise to a conflict between the interests of the Liberty Group or the
MediaOne Group and the interests of the Telewest Group, the prior approval of
the Board consisting solely of the Independent Directors and the Directors
appointed by the MediaOne Group (in the case of an arrangement with the Liberty
Group) or by the Liberty Group (in the case of an arrangement with the MediaOne
Group) shall be required before the Telewest Group can proceed with the
transaction, arrangement or agreement (or amendment thereto), as the case may
be.

7.7 Subject to clause 7.8, any transactions, agreements or arrangements
(including trading arrangements) between any member of the Liberty Group or the
MediaOne Group and the Telewest Group shall be at arm's length on a normal
commercial basis and will be subject to the prior approval of the Board
consisting solely of Independent Directors and the Directors appointed by the
MediaOne Group (in the case of an arrangement with the Liberty Group) or by the
Liberty Group (in the case of an arrangement with the MediaOne Group).

7.8 Clauses 7.4, 7.5, 7.6 and 7.7 shall only apply for so long as the MediaOne
Group and the Liberty Group continue to be the Controlling Shareholder of the
Company.

Rights of first offer, rights of first refusal and change of control

CLAUSE 9.1 IS DELIBERATELY BLANK

9.2 RIGHTS OF FIRST REFUSAL BETWEEN THE LIBERTY GROUP AND THE MEDIAONE GROUP

9.2.1 Clauses 9.2.2 to 9.2.7 shall not apply to any Transfer by a Shareholder to
an Affiliate of that Shareholder or to any Transfers pursuant to a Permitted
Demerger (provided that any transferee who is or becomes a member of the same
Shareholder Group as the transferor, first duly completes, executes and delivers
to the Company a deed of adherence in the form set out in Schedule 2).

9.2.2 Subject to clause 9.2.1, a Liberty Shareholder or MediaOne Shareholder
desiring to make a Transfer of Shares (the SELLER) shall first make a written
offer (the OFFER) to sell such Shares to the MediaOne Group or the Liberty Group
respectively (the RELEVANT PURCHASER) on the same terms and conditions on which
the Seller proposes to Transfer the Shares. If the proposed Transfer is a Public
Transfer, the Seller shall give notice to the Relevant Purchaser stating the
number of Shares it proposes to Transfer and that such Shares will be sold to
the Relevant Purchaser at a price per Share equal to the average of the Closing
Prices for six Trading Days comprising the three Trading Days prior to and
including the date that any notice is sent pursuant to clause 9.2.3 and the
three Trading Days following the date of such notice. If the proposed Transfer
is a Private Transfer, such offer shall state the price and the other terms and
conditions of the proposed Transfer and shall be accompanied by a copy of the
offer from the proposed transferee. The price as so determined or stated in the
Seller's notice shall be the OFFER PRICE. The foregoing notwithstanding, the
Seller may withdraw the Offer without liability to the Relevant


                                      -13-
<PAGE>   17

Purchaser hereunder if the Offer Price, determined with respect to any Public
Transfer, is less than 90 per cent. of the Closing Price on the date of the
Offer (or if such date is not a Trading Day, on the immediately preceding
Trading Day).

9.2.3 The Relevant Purchaser shall have the right for a period of 30 days after
receipt of the Offer to elect to purchase all, but not less than all, of the
Shares offered at the Offer Price (less, in case of a proposed Public Transfer,
any underwriting or sales commission or discount that would have been paid in
the proposed Public Transfer) by giving written notice of acceptance to the
Seller within that period. If the Relevant Purchaser does not elect to purchase
all the Shares offered, the Seller may Transfer the offered Shares pursuant to
the terms disclosed under clause 9.2.2 which, in the case of a Private Transfer,
shall be at a price equal to or greater than the Offer Price. If the offered
Shares are not Transferred within 90 days after the Relevant Purchaser's option
period expires, a new offer shall be made to the Relevant Purchaser before any
Transfer is made.

9.2.4 If in the case of a Private Transfer, a third party's offer involves
consideration other than immediate payment of cash at closing, the Relevant
Purchaser may pay the Fair Market Value of such other consideration, as
determined by agreement between the Seller and the Relevant Purchaser, in cash.
If they cannot agree on such cash equivalent within seven days after the
Relevant Purchaser gives notice of its election to purchase the offered Shares,
the Relevant Purchaser may, by written notice to the Seller, initiate appraisal
proceedings under clause 9.2.5 for determination of the Fair Market Value of
such consideration. The Fair Market Value shall be determined without regard to
income tax consequences to the Seller as a result of receiving cash in lieu of
other consideration. Once the Fair Market Value is determined, (i) the Relevant
Purchaser, in its sole discretion, may elect either to purchase the Shares in
cash by giving notice of such election to the Seller within 10 days after
receipt of the appraiser's decision or to withdraw its acceptance of the Offer,
and (ii) the Seller may in its sole discretion withdraw the Offer provided that
in such case it may not Transfer such Shares pursuant to the proposed Private
Transfer.

9.2.5 Any appraisal of the Fair Market Value of consideration shall be made by
an appraiser jointly appointed by the Liberty Group and the MediaOne Group to
make such determination. If the parties fail to agree on an appraiser within 20
days after receipt of the notice requiring or permitting an appraisal of Fair
Market Value, each of the Liberty Group and the MediaOne Group shall appoint one
appraiser, which shall be an investment banking firm of national repute. The two
appraisers so selected shall each make an appraisal of Fair Market Value within
30 days after their selection. If such determinations vary by 20 per cent. or
more of the higher determination, the two appraisers shall select a third
appraiser with similar qualifications which shall make its determination of such
Fair Market Value within 30 days after its selection. Such third appraiser shall
not be informed of or otherwise consider the appraisals of the other two in
reaching its determination. The Fair Market Value shall be the average of the
two closest values if three appraisals are


                                      -14-
<PAGE>   18

made or, if the determinations of the first two appraisers vary by 20 per cent.
or less of the higher of such two determinations, the average of those two
determinations. If any Shareholder Group fails to appoint an appraiser as
required hereunder, the other Shareholder Group may refer the matter to the
American Arbitration Association, which shall promptly appoint an appraiser
hereunder on behalf of the Shareholder Group failing to make such appointment.
Appraisers appointed under this clause 9.2.5 shall act as experts and not as
arbitrators and, absent fraud or manifest error, the determination of an
appraiser or appraisers hereunder shall be binding on the parties.

9.3 CHANGE IN CONTROL OF LIBERTY OR MEDIAONE

If at any time there is an involuntary Change in Control with respect to
MediaOne Holdings and its Affiliates or Liberty and its Affiliates, MediaOne
Holdings and its Affiliates or Liberty and its Affiliates, as the case may be,
experiencing the Change in Control (the SUBJECT GROUP) shall give notice to the
other group (the RESPONDING GROUP) promptly after the Subject Group becomes
aware of the Change in Control. If at any time a Subject Group experiences a
voluntary Change in Control, the Subject Group shall give notice to the
Responding Group promptly after the terms of the Change in Control are set forth
in a binding agreement. The Responding Group must within 30 days after its
receipt of such notice give notice to the Subject Group either (a) consenting to
the Change in Control or (b) stating the price at which the Responding Group is
willing to sell all of its Shares to the Subject Group or to buy all of the
Subject Group's Shares (the QUOTED PRICE). Failure to give notice of such
election within the time permitted shall be deemed consent to the Change in
Control. If the Responding Group notifies the Subject Group that it does not
consent to the Change in Control, the Subject Group must, within 30 days after
its receipt of the Responding Group's notice, give notice to the Responding
Group of its election to sell all of its Shares to the Responding Group or to
buy all of the Responding Group's Shares, in either case at the Quoted Price.

9.4 GENERAL TRANSFER PROVISIONS

MediaOne Group pursuant to clause 9.1, 9.2 or 9.3 shall take place at the

         and proportions in which the Sale Shares can be transferred by the
         Seller pursuant to clause 9.1.2 or within 30 days after acceptance
         ("Acceptance") by the Seller of the offer contained in any Offer Notice
         pursuant to clause 9.13; and

(b)      in the case of clauses 9.2 and 9.3 on a day specified by the purchaser

         are required by law to be closed) which is no more than 90 days after
         the day of exercise of the relevant purchase option,

or, if later, the date on which all necessary consents to such Transfer by
governmental authorities shall have been obtained. At the closing the Seller
shall deliver certificates representing the Shares to be sold free and clear of
any lien, charge or encumbrance, duly endorsed or accompanied by stock transfers
executed in blank, and such other documents as may be reasonably necessary to
effectuate the sale. The Seller shall give customary representations and
warranties regarding the title of such shares to the Relevant Purchaser(s). The
purchase price (to the extent payable in cash) shall be paid in cash in
immediately available funds.

9.4.2 The Relevant Purchaser may rescind its notice of acceptance given pursuant
to clause 9.2.3 at any time on or prior to the thirtieth day following the date
on which such notice is given (but not thereafter) if (i) prior to the date of
such notice of acceptance the Relevant Purchaser had sought in good faith a
waiver from the Panel with respect to the application of any provision of Rule 9
of the City Code on Takeovers and Mergers which absent such waiver would require
the Relevant Purchaser to offer to purchase all of the outstanding Ordinary
Shares, and (ii) such waiver or any shareholder approval required by the Panel
has been denied (or has not been granted as of the last day of such rescission
period) provided that if the Relevant Purchaser so rescinds its acceptance, the
90 day period referred to in clause 9.4.1(b) shall be extended by the number of
days between the date of such acceptance and the date of rescission.

9.4.3 Notwithstanding any other provision of this clause 9, no Person may
Transfer any Shares unless it has complied with all applicable legal
requirements, including without limitation applicable United States federal and
state securities laws. Upon the exercise by a Person of any right to acquire
Shares hereunder, the parties shall use commercially reasonable efforts to
obtain any necessary consents or approvals of any governmental authorities or
other third parties necessary to promptly effect such Transfer.

(i)  on an issue of Ordinary Shares have the option to subscribe for that number
     of new Ordinary Shares (in such proportions as they may agree and otherwise
     among them pro rata according to their respective shareholdings) necessary
     to permit their Qualifying Group to have ownership of sufficient issued
     Ordinary Shares so as to maintain its Percentage Ownership immediately
     following a Dilutive Issue assuming and provided that such Qualifying

     either:


                                      -19-
<PAGE>   23

         (i)  subscribe for that number of Equivalent Securities (in such
              proportions as they may agree and otherwise among them pro rata
              according to their respective shareholdings) necessary to permit
              their Qualifying Group to have ownership of sufficient issued
              Ordinary Shares so as to maintain its Percentage Ownership
              immediately following such issue assuming that the options under
              clause 10.3 are exercised in full; or

         (ii) on the conversion or exchange of the Equivalent Securities held by
              persons other than the Qualifying Shareholders, subscribe for that
              number of Ordinary Shares necessary to permit the Qualifying
              Shareholders to have ownership of sufficient issued Ordinary
              Shares in aggregate so as to maintain its Percentage Ownership
              immediately following such conversion or exchange assuming that
              the options under clause 10.3 are exercised in full.

Each Qualifying Shareholder shall, within 15 days after receipt of notice from
the Company to the effect that all conditions to such issuance have been
satisfied, notify the Company whether, ands to what extent, it wishes to

MediaOne Group and the Liberty Group agree with each other to consult each other
and, if the exercise of their rights to the desired extent may have implications
under Rule 9 of the City Code on Takeovers and Mergers, to consult the Panel. If
within 10 days of receipt of notice from the Company to the effect that all
conditions to the proposed issuance have been satisfied the Panel has not
granted or has denied a waiver of all requirements under Rule 9 for the Liberty
Group or the MediaOne Group to make a mandatory offer as a result of the
exercise of their rights under clauses 10.3, 10.4 or 10.4A or any shareholder
approval required by the Panel has not been granted or has been denied and both
the MediaOne Group and the Liberty Group wish to exercise their rights under
clauses 10.3, 10.4 or 10.4A to an extent which in aggregate would trigger the
requirement for a mandatory offer under Rule 9, unless Liberty and MediaOne
Holdings otherwise agree, the Liberty Group and the MediaOne Group shall
exercise their rights under clauses 10.3 or 10.4 only to the maximum extent
practicable without triggering any requirement under Rule 9 for a mandatory
offer and, in case of competition, pro rata to their then existing holdings of
Ordinary Shares.

and/or the MediaOne/Liberty Shareholders pursuant to clause 10.3(i), 10.4 or
10.4A(i) shall be subscribed for in cash at a price per share equal to the
average Closing Price for the 10 consecutive Trading Days ending on the Trading
Day immediately preceding the date of the Dilutive Issue. Such Ordinary Shares
shall be issued immediately before the issue of Ordinary Shares which gave rise
to the option described in this clause 10.

<PAGE>   24

10.6A Any Ordinary Shares subscribed for by TW Holdings and/or the
MediaOne/Liberty Shareholders pursuant to Clause 10.3(ii) or 10.4A(ii) shall be
subscribed in cash at a price per share equal to the average Closing Price for
the 10 consecutive Trading Days ending on the Trading Day immediately preceding
the date of issue of the Ordinary Shares arising from the conversion/exchange of
the Equivalent Securities that gave rise to TW Holdings' and/or the
MediaOne/Liberty Shareholders' right to subscribe. Such Ordinary Shares shall be
issued immediately before the issue of the Ordinary Shares which gave rise to
the option arising on conversion/exchange of the Equivalent Securities.

10.6B Any Equivalent Securities subscribed for by TW Holdings and/or the
MediaOne/Liberty Shareholders pursuant to Clause 10.3(ii) or 10.4A(ii) shall be
subscribed in cash at a price per Equivalent Security equal to the subscription
price of such Equivalent Securities to third party investors at the time of
their issue.

10.7 The Company will seek statutory authority to allot Ordinary Shares
(pursuant to section 80 of the Act) and for the disapplication of the statutory
pre-emption rights (pursuant to section 95 of the Act) for a period of five
years and hereby agrees to use its reasonable endeavours to renew any and every
such statutory authority to allot and for the disapplication of the pre-emption
rights thereafter for so long as the Company is obligated by the anti-dilution
provisions of this clause 10. The Company further undertakes that it shall only
increase the Fully Diluted Ordinary Shares if thereafter there is sufficient
authorised but unissued share capital for the Company to comply with its
obligations pursuant to this clause 10 and also only if there are outstanding
and valid a statutory authority to allot (pursuant to section 80 of the Act) and
a disapplication of the statutory pre-emption rights (pursuant to section 95 of
the Act) in respect of sufficient Ordinary Shares for the Company to comply with
its obligations under this clause. The Shareholders undertake to each other and
to the Company to vote in favour of any such proposed resolutions.

10.8 The Company shall use all reasonable efforts to ensure that all Ordinary
Shares issued pursuant to this clause 10 are admitted to the Official List by
the London Stock Exchange.

10.9 MediaOne, Liberty and TW Holdings agree that, if as a result of the
conversion of the Company's outstanding 5.4% senior convertible notes due 2007,
TW Holdings and/or the MediaOne/Liberty Shareholders become entitled to exercise
their option to subscribe for Ordinary Shares under Clause 10.3(ii) (in relation
to the 50.1% threshold referred to in that clause), they shall seek to satisfy
their right to subscribe for such shares by purchasing Ordinary Shares in the
market and shall only exercise such option to the extent that such purchases are
not possible either (i) at or close to the price per share that would be payable
on exercise of their options in Clause 10, or (ii) without incurring an
obligation to make a mandatory cash offer for the Company under Rule 9, Provided
always that this Clause 10.9 shall not apply to


                                      -21-

a conversion of such notes that would cause a Qualifying Shareholder's
Qualifying Group to cease being a 15 Per Cent. Group or a 7.5 Per Cent. Group as
applicable.

shareholders generally, to ensure that any issuance of Shares is done in a

maintain their percentage Ordinary Share ownership in the Company. The Company
shall apply for all such Ordinary Shares to be admitted to the Official List by
the London Stock Exchange.

12.1.2 acquire an equity interest in any Person (other than the Company, TWE,
Flextech plc, MPC or their Controlled Affiliates) if (a) at the time of such
acquisition such Person directly or indirectly through one or more Controlled
Affiliates owns any Cable Telephony or Cable Television systems in the UK
(excluding in respect of terrestrial TV), unless immediately prior to such

12.5 Notwithstanding the restrictions set forth in clauses 12.1 and 12.2
MediaOne Holdings, MediaOne, Liberty Media Corporation and Liberty, and their
respective Controlled Affiliates (each a RELEVANT INVESTOR) may acquire and
subsequently own assets comprising Cable Television or Cable Telephony systems
in the UK if, prior to the Relevant Investor acquiring such assets, it first
offers the opportunity to the Company, stating the terms on which the
opportunity is available. The Company shall within 30 days after receipt of such
notice give notice to the Relevant Investor stating whether it wishes to
undertake such opportunity and failure to do so shall be deemed re election of
the right to undertake the opportunity. The directors appointed by the
Shareholder Group of which the Relevant Investor is a member (RELEVANT INVESTOR
GROUP) shall not vote with respect to any decision by the Company whether to
pursue an opportunity offered by the Relevant Investor Group, and if the
Relevant Investor Group votes as a shareholder against any means of funding the
pursuit of such opportunity which requires shareholder approval (other than a
guarantee or similar agreement that would impose an obligation on the Relevant
Investor Group), the Relevant Investor Group shall not pursue the opportunity
independently. In the event that the Company notifies the Relevant Investor that
it does not wish to undertake such opportunity then within a further 180 days of
such notification the Relevant Investor may take all necessary actions to enter
into agreements relating to such opportunity (on terms no more favourable than
those offered to the Company) and to the extent the Relevant Investor does not
do so then before entering into such agreements after the expiry of such 180 day
period it must first re-offer the opportunity to the Company on the terms set
out herein. Except as stated herein, MediaOne, MediaOne Holdings, Liberty Media
Corporation and Liberty and their Controlled Affiliates shall be free to pursue
any other business opportunity anywhere in the world.

Kingdom;

12.6.2 owning or acquiring an interest in any Person engaged in (a) Wireless

(c) any subscriber voice or data telecommunications transmission service that

System for Cable Telephony customers;

12.6.3 directly or indirectly providing any subscriber voice or data
telecommunications transmission service (including but not limited to Wireless
Telephony) that operates only in part by cable links to subscribers' premises
(except in respect of the interconnection of such service to cable links which

to engage in such service outside of such interconnection shall not be
restricted);

12.6.4 owning or acquiring, directly or indirectly, an interest in any Person
that provides, or is providing, programming or content services in the United
Kingdom; or

12.6.5 acquiring an interest in any Person whose annual gross revenues from
Cable Television and Cable Telephony in the United Kingdom in its most recently
completed fiscal year prior to the acquisition constituted 20 per cent. or less
of its total annual gross revenues, provided that if any of MediaOne Holdings,
Liberty or their respective Controlled Affiliates acquires in accordance with
this clause 12.6.5 after the date hereof a Controlling interest in any Person
(other than Flextech plc, TWE or MPC or their Controlled Affiliates) which owns
Cable Television or Cable Telephony assets in the United Kingdom, the Company
shall have the option (subject to third party rights and any contractual
restrictions) so long as clause 12.1, 12.2, 12.3 or 12.4, as the case may be, is
applicable to the acquirer's Shareholder Group, to acquire the interest in the
Cable Television and Cable Telephony assets in the United Kingdom of that Person
for the Fair Market Value thereof payable in cash provided that (a) the option
must be exercised, if at all, by the Company by giving written notice to the
Relevant Investor within 30 days after the Relevant Investor gives notice to the
Company of the existence of such opportunity and closed within 120 days after
the date of the notice of exercise and (b) the Relevant Investor acquiring such
interest shall not vote on any decision whether to exercise the option granted

12.7 Each of the exceptions set forth in clauses 12.6.1 through 12.6.5. is
separately applicable and independent of any of the other exceptions.

12.8 Whenever the Fair Market Value of any transaction or interest is required
to be determined hereunder, the Relevant Investor and the Company may upon
notice require that Fair Market Value determination be made by an appraiser
jointly appointed by the Relevant Investor and the Company. If the Relevant
Investor and the Company fail to agree on an appraiser within 20 days after
receipt of the notice requiring an appraisal of Fair Market Value, they shall
each appoint one appraiser, which shall be an investment banking firm of
national repute in the UK. The two appraisers so selected shall each make an
appraisal of Fair Market Value within 30 days after their selection. If such
determinations vary by 20 per cent. or more of the higher determination, the two
appraisers shall select a third appraiser with similar qualifications which
shall make its determination of such Fair Market Value within 30 days after its
selection. Such third appraiser shall not be informed of or otherwise consider
the appraisals of the other two in reaching its determination. The Fair Market
Value shall be the average of the two closest values if three appraisals are
made or, if the determinations of the first two appraisers vary by less than 20
per cent. of the higher of such two determinations, the average of those two
determinations. If any party fails to appoint an appraiser as required
hereunder, the other party may refer the matter to the American Arbitration
Association, which shall promptly appoint an appraiser hereunder on behalf of
the party failing to make such appointment. The 30 - day period specified in
clause 12.6.5 above shall be suspended pending final determination of Fair
Market Value. Appraisers appointed under this clause shall act as experts and
not as arbitrators and, absent fraud or manifest error, the determination of an
appraiser hereunder shall be binding on the parties.

the Liberty Group, for so long as it is a Qualifying Group, that the business of
the Company and its Controlled Affiliates shall be limited to providing Cable

United Kingdom and all matters incidental thereto, including television
programming in the United Kingdom incidental to the Company's Cable Television

Company shall not own or acquire an equity interest in any Person that engages
in a business other than those in which the Company is permitted to engage
pursuant to this clause 13. Neither the Company nor any of its Affiliates shall
use the "Telewest" mark (or any mark confusingly similar to it) outside of the
UK and the Liberty Shareholders, the MediaOne Shareholders and their respective
Affiliates shall not use the "Telewest" mark (or any mark confusingly similar to
it) within the UK.

(a)      In certain agreements that established a partnership to operate the One
         2 One mobile radio voice network, MediaOne has agreed to certain
         contractual restrictions which provide that neither MediaOne nor its
         Affiliates (including the Company) will directly or indirectly carry on
         or have a shareholding or other economic interest in a person which
         carries on or has applied for a license to carry on, as all or part of
         its business the activity of running a mobile radio voice telephony
         network for the provision of telecommunication services to the general
         public within any part of the UK. So long as MediaOne owns an equity
         interest in the One 2 One partnership or any successor to the One 2 One
         partnership (including the current partnership after admission of one
         or more new partners) in excess of the minimum interest specified in
         the One 2 One agreement as of the date of this Agreement, such
         contractual restrictions contained in any agreements governing the
         business of a successor to the One 2 One partnership (including the
         current partnership after admission of one or more new partners) shall
         become part of this Schedule 1 provided that such restrictions are not
         broader in scope than those in effect on the date of this Agreement.

(b)      MediaOne has agreed that MediaOne and certain of its affiliates will
         not compete with Time Warner Entertainment Company, L.P. (TWE) in
         certain businesses, and that they will offer TWE a right of first
         refusal in certain circumstances, as disclosed in the IPO Documents.

                                     PART II

         in English-language programming business in the United Kingdom and
         Europe under certain circumstances described in the IPO Documents.

(b)      In an agreement relating to the establishment of a joint venture
         between BBC Worldwide and Flextech plc for the establishment and
         broadcast of television programme services in the United Kingdom,
         Liberty has agreed that it will not itself, and that it will procure
         that no company of which it has voting control will, acquire an
         interest in excess of 20 per cent. of the issued share capital of a
         company which owns a commercial broadcast television channel which
         competes with one or more of the channels to be established under such
         joint venture.
