Item 5.    Other Events.

     On February 5, 1998 NTL Incorporated  ("NTL") announced that it had entered
into an agreement and plan of  amalgamation  (the  "Agreement")  with Comcast UK
Cable Partners Limited ("Comcast UK").

     Under the Agreement,  Comcast UK shareholders will receive 0.3745 shares of
NTL Common Stock for each share of Comcast UK Common Stock. Based on the closing
price of NTL Common Stock on February 4, 1998,  the purchase price is $11.98 per
Comcast UK share,  for a total equity value of approximately  $600 million.  The
Agreement  contains  provisions  such that if the purchase  price per Comcast UK
share falls below $10.00, Comcast UK has the right to terminate the transaction,
subject  to NTL's  right to adjust  the  exchange  ratio  such that  Comcast  UK
shareholders  would receive  $10.00 for each Comcast UK share.  At September 30,
1997, Comcast UK had total debt of approximately $397 million, which is expected
to remain outstanding.

     Completion of the transaction is subject to customary  closing  conditions,
including  regulatory  approvals,  NTL and Comcast UK  shareholder  approval and
consents from their respective  bondholders.  Under certain  circumstances,  the
consideration  payable  to Comcast  shareholders  may be  adjusted  based on the
proceeds of the  potential  exercise  of certain  rights of first  refusal  with
respect to Comcast's interests in London and Birmingham.

     Comcast UK  operates  telephony/cable  networks  in the  United  Kingdom in
Cambridge  and  Teesside,  and has  interests in London  (50.0%  ownership)  and
Birmingham  (27.5%  ownership).  Comcast  UK has a total  of  approximately  1.1
million  equity  homes  under  franchise.   As  of  September  30,  1997,  on  a
proportionate basis Comcast UK had passed  approximately  660,000 homes, and had
approximately 210,000 residential telephony customers, 160,000 residential cable
television customers and 6,600 business telephony customers.

     NTL is a  leading  alternative  telecommunications  company  in the  United
Kingdom.   The  Company  offers  local  business  and   residential   telephony,
residential cable television and Internet services over advanced broadband fiber
networks in six major franchise  areas in the UK. Through its national  telecoms
services  division,  the Company owns and operates one of only five  independent
national  telecoms  networks in the UK, and offers national  business  telecoms,
national and international carrier  telecommunications  services,  and satellite
and radio  communications  services.  The Company's  broadcast services division
operates a national broadcast  transmission network of more than 1,200 owned and
shared transmission sites, and offers digital and analog broadcast  transmission
services to major television and radio stations nationwide in the UK.

     A copy of the press release  issued by the Company  announcing the above is
attached hereto as an exhibit and incorporated herein by reference.

     WHEREAS,  the parties desire to make certain  representations,  warranties,
covenants  and  agreements  in  connection  with  the  Amalgamation  and also to

     NOW,  THEREFORE,  in  consideration  of  the  representations,  warranties,

     forth in Section 5.20) validly issued,  fully paid and nonassessable shares
     of NTL Class D Stock .

          The  consideration to be issued to holders of Partners Common Stock is
     referred to herein as the "Amalgamation Consideration." As of the Effective
     Time,  all the  Partners  Common Stock shall no longer be  outstanding  and
     shall  automatically be cancelled and shall cease to exist, and each holder
     of a  certificate  representing  any such shares of Partners  Common  Stock
     (other than Dissenting  Shares) shall cease to have any rights with respect
     thereto, except the right to receive the Amalgamation Consideration and any
     cash in lieu of fractional  shares of NTL Common Stock to be issued or paid
     in consideration  therefor upon surrender of such certificate in accordance
     with Section 2.2, without interest.

     (c)  Conversion of Shares of Sub. Each issued and  outstanding  share,  par
value .01 (pound  sterling) per share, of Sub shall be converted into and become
one  validly  issued,  fully  paid and  nonassessable  share of the  Amalgamated
Company by virtue of the Amalgamation and without any action on the part of NTL.

     (d) Shares of  Dissenting  Shareholders.  Notwithstanding  anything in this
Agreement to the contrary,  any issued and outstanding shares of Partners Common
Stock  held by a person  who did not vote in favor of the  Amalgamation  and who
complies with all the  provisions of Bermuda law concerning the right of holders
of Partners Common Stock to require appraisal of their shares of Partners Common
Stock  by  the  Supreme  Court  of  Bermuda  (such  shareholder,  a  "Dissenting
Shareholder",  and such shares,  "Dissenting  Shares") shall be cancelled at the
Effective Time in consideration  for the right to receive such  consideration as
may  be  payable  to  such  Dissenting   Shareholder   upon  completion  of  the
Amalgamation  pursuant  to the laws of Bermuda.  In the event that a  Dissenting
Shareholder fails to perfect, effectively withdraws or otherwise loses any right
to appraisal and payment under the Companies  Act, such  Dissenting  Shareholder
shall no longer  have any right to  appraisal  thereunder.  Any such  Dissenting
Shareholder shall be entitled to elect to receive the Amalgamation Consideration
and any cash in

 
                                      7

<PAGE>


lieu of  fractional  shares of NTL Capital  Stock.  Partners  shall give NTL (i)
prompt  notice of any written  demands for  appraisal  of  Dissenting  Shares or
withdrawals  of such demands  received by Partners and (ii) the  opportunity  to
participate in and direct all  negotiations  and proceedings with respect to any
such demands.  Except as required by Section 106 of the Companies  Act, prior to
the Effective  Time,  Partners shall not,  without the prior written  consent of
NTL,  make any payment with respect to, or settle,  offer to settle or otherwise
negotiate, any such demands.

     SECTION 2.2  Exchange of  Certificates.  (a) Exchange  Agent.  Prior to the
Effective  Time,  NTL  shall  enter  into an  agreement  with such bank or trust
company as may be designated by NTL and be reasonably  satisfactory  to Partners
(the  "Exchange  Agent"),  which shall  provide that NTL shall  deposit with the
Exchange  Agent as of the  Effective  Time,  for the  benefit of the  holders of
Partners Common Stock,  for exchange in accordance with this Article II, through
the Exchange  Agent,  certificates  representing  NTL Capital  Stock (as defined
below)  (such  shares of NTL  Capital  Stock,  together  with any  dividends  or
distributions  with respect thereto with a record date after the Effective Time,
any Excess Shares (as defined in Section  2.2(e)) and any cash  (including  cash
proceeds from the sale of the Excess  Shares)  payable in lieu of any fractional
shares of NTL Capital  Stock  being  hereinafter  referred  to as the  "Exchange
Fund") issuable  pursuant to Section 2.1 in exchange for  outstanding  shares of
Partners Common Stock.

     (b) Exchange Procedures.  Promptly after the Effective Time, NTL will cause
the  Exchange  Agent  to mail to each  registered  holder  of a  certificate  or
certificates other than Dissenting Shareholders, if any, which immediately prior
to the Effective Time  represented  outstanding  shares of Partners Common Stock
(the "Certificates") whose shares were cancelled in consideration of the receipt
of the  Amalgamation  Consideration  pursuant  to Section  2.1,  (i) a letter of
transmittal  (which shall specify that delivery  shall be effected,  and risk of
loss and  title to the  Certificates  shall  pass,  only  upon  delivery  of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Partners and NTL may reasonably specify) and (ii) instructions for
use in surrendering the Certificates in


                                       8
<PAGE>


exchange for the Amalgamation Consideration. Upon surrender of a Certificate for
cancellation  to the Exchange  Agent,  together with such letter of transmittal,
duly  executed,  and such other  documents as may  reasonably be required by the
Exchange Agent, the holder of such  Certificate  shall be entitled to receive in
consideration therefor a certificate representing that number of whole shares of
NTL Common  Stock,  NTL Class C Stock or NTL Class D Stock  (collectively,  "NTL
Capital  Stock")  which such  holder has the right to  receive  pursuant  to the
provisions  of this  Article II,  certain  dividends or other  distributions  in
accordance  with Section 2.2(c) and cash in lieu of any fractional  share of NTL
Capital  Stock  in  accordance  with  Section  2.2(e),  and the  Certificate  so
surrendered  shall  forthwith  be  cancelled.  In the event of a surrender  of a
Certificate   representing  shares  of  Partners  Common  Stock  which  are  not
registered  in the  transfer  records of  Partners  under the name of the person
surrendering such Certificate,  a certificate  representing the proper number of
shares of NTL Capital  Stock may be issued to a person  other than the person in
whose name the  Certificate  so  surrendered  is registered if such  Certificate
shall be properly  endorsed or  otherwise be in proper form for transfer and the
person  requesting  such issuance shall pay any transfer or other taxes required
by reason of the issuance of shares of NTL Capital  Stock to a person other than
the registered  holder of such  Certificate or establish to the  satisfaction of
NTL that  such tax has been  paid or is not  applicable.  Until  surrendered  as
contemplated by this Section 2.2, each  Certificate  shall be deemed at any time
after  the  Effective  Time to  represent  only the right to  receive  upon such
surrender the Amalgamation  Consideration which the holder thereof has the right
to receive in respect of such  Certificate  pursuant to the  provisions  of this
Article II, certain dividends or other  distributions in accordance with Section
2.2(c)  and  cash  in lieu of any  fractional  share  of NTL  Capital  Stock  in
accordance with Section 2.2(e).  No interest shall be paid or will accrue on any
cash  payable to holders of  Certificates  pursuant  to the  provisions  of this
Article II.

     (c) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions  with  respect to NTL  Capital  Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of


                                       9
<PAGE>


NTL  Common  Stock  represented  thereby,  and,  in  the  case  of  Certificates
representing Partners Common Stock, no cash payment in lieu of fractional shares
shall  be paid to any such  holder  pursuant  to  Section  2.2(e),  and all such
dividends,  other  distributions  and cash in lieu of  fractional  shares of NTL
Capital  Stock shall be paid by NTL to the Exchange  Agent and shall be included
in the Exchange  Fund, in each case until the surrender of such  Certificate  in
accordance with this Article II. Subject to the effect of applicable  escheat or
similar laws, following surrender of any such Certificate there shall be paid to
the holder of the  certificate  representing  whole shares of NTL Capital  Stock
issued in  consideration  therefor,  without  interest,  (i) at the time of such
surrender,  the amount of  dividends or other  distributions  with a record date
after the Effective Time  theretofore  paid with respect to such whole shares of
NTL Capital Stock and, in the case of Certificates  representing Partners Common
Stock,  the  amount of any cash  payable  in lieu of a  fractional  share of NTL
Capital  Stock to which such holder is entitled  pursuant to Section  2.2(e) and
(ii)  at the  appropriate  payment  date,  the  amount  of  dividends  or  other
distributions  with a record  date after the  Effective  Time and with a payment
date  subsequent to such surrender  payable with respect to such whole shares of
NTL Capital Stock.

     (d) No Further Ownership Rights in Partners Common Stock. All shares of NTL
Capital Stock issued upon the surrender of  Certificates  in accordance with the
terms of this Article II  (including  any cash paid pursuant to this Article II)
shall be deemed to have  been  issued  (and  paid) in full  satisfaction  of all
rights   pertaining  to  the  shares  of  Partners  Common  Stock,   theretofore
represented by such Certificates, subject, however, to the Amalgamated Company's
obligation  to pay any dividends or make any other  distributions  with a record
date  prior to the  Effective  Time  which  may have  been  declared  or made by
Partners on such  shares of Partners  Common  Stock which  remain  unpaid at the
Effective  Time, and there shall be no further  registration of transfers on the
stock transfer books of the Amalgamated Company of the shares of Partners Common
Stock which were outstanding  immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Amalgamated Company or the
Exchange Agent for any reason,


                                       10
<PAGE>


they shall be cancelled in accordance  with this Article II, except as otherwise
provided by law.

     (e)  No  Fractional  Shares.  (i) No  certificates  or  scrip  representing
fractional  shares of NTL Capital  Stock shall be issued upon the  surrender  of
Certificates, no dividend or distribution of NTL shall relate to such fractional
share interests and such  fractional  share interests will not entitle the owner
thereof to vote or to any rights of a stockholder of NTL.

          (ii) As promptly as  practicable  following  the Effective  Time,  the
     Exchange Agent shall determine the excess of (A) the number of whole shares
     of NTL Capital  Stock  delivered to the  Exchange  Agent by NTL pursuant to
     Section 2.2(a) over (B) the aggregate number of whole shares of NTL Capital
     Stock to be distributed to former holders of Partners Common Stock pursuant
     to Section  2.2(b) (such excess being herein  called the "Excess  Shares").
     Following the Effective  Time, the Exchange  Agent shall,  on behalf of the
     former stockholders of Partners,  sell the Excess Shares at then-prevailing
     prices on the NASDAQ Stock Market ("NASDAQ") or otherwise all in the manner
     provided in Section 2.2(e)(iii).

          (iii) The sale of the Excess  Shares by the  Exchange  Agent  shall be
     executed on the NASDAQ  through one or more member  firms of the NASDAQ and
     shall be executed  in round lots to the extent  practicable.  The  Exchange
     Agent  shall use  reasonable  efforts  to  complete  the sale of the Excess
     Shares as promptly following the Effective Time as, in the Exchange Agent's
     sole judgment, is practicable  consistent with obtaining the best execution
     of such  sales in light of  prevailing  market  conditions.  Until  the net
     proceeds  of such sale or sales  have been  distributed  to the  holders of
     Certificates  formerly  representing  Partners  Common Stock,  the Exchange
     Agent  shall hold such  proceeds  in trust for such  holders  (the  "Common
     Shares Trust"). The Amalgamated Company shall pay all commissions, transfer
     taxes and other out-of-pocket transaction costs, including the expenses and
     compensation of the Exchange Agent incurred in connection with such sale of
     the Excess Shares.  The Exchange  Agent shall  determine the portion of the
     Common Shares Trust to


                                       11

<PAGE>


     which each former holder of Partners  Common Stock is entitled,  if any, by
     multiplying the amount of the aggregate net proceeds  comprising the Common
     Shares  Trust by a fraction,  the  numerator  of which is the amount of the
     fractional  share  interest to which such former holder of Partners  Common
     Stock is entitled  (after taking into account all shares of Partners Common
     Stock held at the  Effective  Time by such holder) and the  denominator  of
     which is the aggregate  amount of fractional  share  interests to which all
     former holders of Partners Common Stock are entitled.

          (iv)  Notwithstanding  the provisions of Section 2.2(e)(ii) and (iii),
     the  Amalgamated  Company may, at the option of NTL exercised  prior to the
     Effective  Time,  in lieu of the issuance and sale of Excess Shares and the
     making of the payments hereinabove contemplated,  pay each former holder of
     Partners  Common  Stock an amount in cash equal to the product  obtained by
     multiplying  (A) the fractional  share interest to which such former holder
     (after taking into account all shares of Partners  Common Stock held at the
     Effective  Time by such holder) would  otherwise be entitled by (B) the NTL
     Average  Stock Price  determined  as of the fifth  trading day prior to the
     Closing Date, and, in such case, all references herein to the cash proceeds
     of the sale of the Excess Shares and similar  references shall be deemed to
     mean and refer to the  payments  calculated  as set  forth in this  Section
     2.2(e)(iv).

          (v) As soon as practicable  after the  determination  of the amount of
     cash, if any, to be paid to holders of Certificates  formerly  representing
     Partners Common Stock with respect to any fractional share  interests,  the
     Exchange  Agent  shall  make  available  such  amounts  to such  holders of
     Certificates  formerly representing Partners Common Stock subject to and in
     accordance with the terms of Section 2.2(c).

     (f)  Termination  of Exchange  Fund. Any portion of the Exchange Fund which
remains  undistributed  to the holders of the  Certificates for six months after
the Effective  Time shall be delivered to NTL,  upon demand,  and any holders of
the  Certificates  who have not thereto-


                                       12
<PAGE>


fore complied with this Article II shall thereafter look only to NTL for payment
of their claim for  Amalgamation  Consideration,  any dividends or distributions
with respect to NTL Capital Stock and any cash in lieu of  fractional  shares of
NTL Capital Stock.

     (g) No Liability.  None of NTL, Sub, Partners,  the Amalgamated  Company or
the Exchange Agent shall be liable to any person in respect of any shares of NTL
Capital Stock, any dividends or distributions with respect thereto,  any cash in
lieu of  fractional  shares of NTL Capital  Stock or any cash from the  Exchange
Fund, in each case  delivered to a public  official  pursuant to any  applicable
abandoned property, escheat or similar law.

     (h)  Investment of Exchange  Fund. The Exchange Agent shall invest any cash
included  in the  Exchange  Fund,  as directed  by NTL,  on a daily  basis.  Any
interest and other income resulting from such investments shall be paid to NTL.

     (i) Lost  Certificates.  If any Certificate shall have been lost, stolen or
destroyed,  upon the making of an affidavit of that fact by the person  claiming
such  Certificate  to be lost,  stolen or  destroyed  and,  if  required  by the
Amalgamated  Company,  the posting by such  person of a bond in such  reasonable
amount as the Amalgamated Company may direct as indemnity against any claim that
may be made against it with  respect to such  Certificate,  the  Exchange  Agent
shall issue in  exchange  for such lost,  stolen or  destroyed  Certificate  the
Amalgamation   Consideration  and,  if  applicable,  any  unpaid  dividends  and
distributions on shares of NTL Capital Stock  deliverable in respect thereof and
any cash in lieu of fractional shares, in each case pursuant to this Agreement.

     SECTION  2.3  Certain  Adjustments.  If  between  the date  hereof  and the
Effective Time, the outstanding shares of Partners Common Stock or of NTL Common
Stock shall be changed into a different number of shares, including by reason of
any  reclassification,  recapitalization,  split-up,  combination or exchange of
shares,  or any dividend  payable in stock or other securities shall be declared
thereon  with a record date within such period,  the  Exchange  Ratio or, in the
cases of clause (b)(i),  (ii),  (iii), (iv) or (v) of Section 2.1, the number of


                                       13
<PAGE>


shares of NTL Common  Stock,  NTL Class C Stock and NTL Class D Stock  issuable,
shall be adjusted accordingly to provide to the holders of Partners Common Stock
the same economic effect as contemplated by this Agreement prior to such change.


                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

     SECTION 3.1 Representations and Warranties of Partners. Except as disclosed
in the Partners SEC Documents (as defined in Section  3.1(g)) or as set forth on
the  Disclosure  Schedule  delivered by Partners to NTL in  connection  with the
execution of this  Agreement  (the  "Partners  Disclosure  Schedule") and making
reference to the particular  subsection of this Agreement to which  exception is
being taken, Partners represents and warrants to NTL as follows:

          (a)  Organization,  Standing and Corporate Power. (i) Each of Partners
     and its  subsidiaries (as defined in Section 8.3) is a corporation or other
     legal entity duly  organized,  validly  existing and in good standing (with
     respect to  jurisdictions  which  recognize such concept) under the laws of
     the  jurisdiction in which it is organized and has the requisite  corporate
     or other power,  as the case may be, and authority to carry on its business
     as now being conducted, except, as to subsidiaries, for those jurisdictions
     where  the  failure  to be so  organized,  existing  or  in  good  standing
     individually or in the aggregate  would not have a material  adverse effect
     (as  defined  in  Section  8.3)  on  Partners.  Each  of  Partners  and its
     subsidiaries  is duly  qualified  or licensed to do business and is in good
     standing (with respect to  jurisdictions  which  recognize such concept) in
     each  jurisdiction  in which the nature of its  business or the  ownership,
     leasing  or  operation  of  its  properties  makes  such  qualification  or
     licensing necessary, except for those jurisdictions where the failure to be
     so qualified or licensed or to be in good standing  individually  or in the
     aggregate would not have a material adverse effect on Partners.

     accurate  records of all meetings and accurately  reflect all other actions
     taken by the stockholders, the Board of Directors and all committees of the
     Board of Directors of Partners since January 1, 1996 and prior to September
     25, 1997.

     (b) Subsidiaries and Affiliates.  Section 3.1(b) of the Partners Disclosure

any other  restriction  (including any restriction on the right to vote, sell or
otherwise  dispose of such capital stock or other ownership  interests).  At the
Effective Time, the Amalgamated  Company will have legal and beneficial title of
Partners' ownership interests of the Significant Affiliates,  subject to (i) the

the 1995 Stock  Option  Plan,  complete  and  correct  copies of which have been

Agreement.  No consent,  approval,  order or  authorization  of, action by or in
respect of, or  registration,  declaration or filing with,  any federal,  state,
local or foreign  government,  any court,  administrative,  regulatory  or other
governmental   agency,   commission   or   authority   or  any   nongovernmental

other  information  incorporated  therein) with the SEC since September 20, 1994
(the "Partners SEC Documents").  As of their respective  dates, the Partners SEC
Documents  complied  in all  material  respects  with  the  requirements  of the
Securities Act of 1933, as amended (the "Securities  Act"), or the Exchange Act,

thereunder  applicable to such Partners SEC Documents,  and none of the Partners
SEC Documents  when filed  contained any untrue  statement of a material fact or

they were made, not misleading.

          (ii) The financial statements of Partners included in the Partners SEC
     Documents  comply as to form, as of their  respective  dates of filing with

     and the published  rules and  regulations of the SEC with respect  thereto,
     have  been  prepared  in  accordance  with  GAAP  (except,  in the  case of
     unaudited  statements,  as  permitted by Form 10-Q of the SEC) applied on a
     consistent basis during the periods involved (except as may be indicated in
     the  notes  thereto)  and  fairly  present  in all  material  respects  the
     consolidated   financial   position  of  Partners   and  its   consolidated
     subsidiaries as of the dates thereof and the consolidated  results of their
     operations and cash flows for the periods then ended (subject,  in the case
     of unaudited statements, to normal year-end audit adjustments).  Except (A)

     incurred in connection with this Agreement or the transactions contemplated
     hereby, neither Partners nor any of its subsidiaries has any liabilities or
     obligations of any nature which,  individually  or in the aggregate,  would
     have a material adverse effect on Partners.

          (iii)  Section  3.1(e)  of  the  Partners   Disclosure  Schedule  (the
     "Preliminary  Financial  Statements")  accurately sets forth as of the date
     hereof the most recently  available  version of the unaudited balance sheet
     and financial  statements of Partners,  its  subsidiaries  and  Significant
     Affiliates as of and for the year ended December 31, 1997.

     (f)  Information  Supplied.  None  of  the  information  supplied  or to be
supplied in writing by Partners  specifically  for inclusion or incorporation by
reference in (i) the registration statement on Form S-4 to be filed with the SEC
by NTL in connection  with the issuance of NTL Common Stock in the  Amalgamation
(the "Form S-4")  will,  at the time the Form S-4  becomes  effective  under the
Securities Act, contain any untrue statement of a material fact or omit to state
any  material  fact  required  to be stated  therein  or  necessary  to make the
statements therein not misleading or (ii) the Joint Proxy Statement will, at the
date  it is  first  mailed  to  Partners's  stockholders  or at the  time of the
Partners Stockholders  Meeting,  contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements  therein, in light of the circumstances under which
they are made, not misleading.  The Joint Proxy Statement will comply as to form
in all material respects with the requirements of the Exchange Act and the rules
and regulations thereunder, except that no representation or warranty is made by
Partners with respect to statements made or  incorporated  by reference  therein
based on information supplied by NTL specifically for inclusion or incorporation
by reference in the Joint Proxy Statement.

     (g)  Absence of  Certain  Changes or  Events.  Except (x) as  disclosed  in
Section 3.1(g) of the Partners Disclosure Schedule, (y) for liabilities incurred
in connection with this Agreement or the transactions contemplated hereby or (z)

change in GAAP,  any change in  accounting  methods,  principles or practices by
Partners materially affecting its assets,  liabilities or business, (vi) any tax
election that  individually  or in the aggregate  would have a material  adverse
effect on Partners or any of its tax  attributes or any settlement or compromise
of any material  income tax liability,  or (vii) any action taken by Partners or
any of the  Partners  subsidiaries  during the period  from  December  31,  1996
through the date of this  Agreement  that,  if taken  during the period from the
date of this Agreement  through the Effective Time would  constitute a breach of
Section 4.1(a).

          (h) Compliance with Applicable  Laws;  Litigation.  (i) Partners,  its
     subsidiaries, Sig-

     exemptions,   orders,  registrations  and  approvals  of  all  Governmental
     Entities which are required for the operation of the respective  businesses
     of Partners, its subsidiaries and its Significant Affiliates (the "Partners
     Permits"),  except  where the  failure  to have any such  Partners  Permits
     individually or in the aggregate  would not have a material  adverse effect
     on Partners.  Partners and its subsidiaries and its Significant  Affiliates
     are in compliance with the terms of the Partners Permits and all applicable
     statutes, laws, ordinances, rules and regulations, except where the failure
     so to comply  individually  or in the aggregate,  would not have a material
     adverse effect on Partners. No action, demand, requirement or investigation
     by any Governmental Entity and no suit, action or proceeding by any person,
     in each  case  with  respect  to  Partners  or any of its  subsidiaries  or
     Significant Affiliates or any of their respective properties is pending or,
     to the knowledge (as defined in Section 8.3) of Partners, threatened, other
     than,  in each  case,  those the  outcome of which  individually  or in the
     aggregate  would not (A) have a material  adverse effect on Partners or (B)
     reasonably  be  expected  to  impair in any  material  way the  ability  of
     Partners  to perform its  obligations  under this  Agreement  or prevent or
     materially delay the  consummation of any of the transactions  contemplated
     by this Agreement.

          (ii) None of Partners,  any Partners  subsidiary,  or any  Significant
     Affiliate is subject to any outstanding  order,  injunction or decree which
     has had or, insofar as can be reasonably  foreseen,  individually or in the
     aggregate will have a material adverse effect on Partners.

     (i)  Incentive  Compensation/Benefit  Plans.  Partners has delivered to NTL
true and  complete  copies of the  documents  listed on  Schedule  3.1(i) of the
Partners Disclosure Schedule.

          (i) With respect to any employee  benefit  plans and  arrangements  of
     Partners and its subsidiaries (the "Partners Benefit Plans"), Partners, its
     subsidiaries and any Partners Benefit Plans have


                                       22
<PAGE>

     been operated, and are, in compliance with the applicable provisions of the
     Employee Retirement Income Security Act of 1974, as amended ("ERISA"),  the
     Code and all other applicable laws.

          (ii) No Partners  Benefit Plan is subject to Title IV of ERISA or is a
     "multiemployer  plan" within the meaning of Section 3(37) of ERISA. Neither
     Partners nor any of its subsidiaries has incurred any unsatisfied liability
     under Title IV of ERISA.  None of Partners nor any of its  subsidiaries has
     any contingent liability under Section 4204 of ERISA.

          (iii) None of Comcast Teesside Limited ("Comcast  Teesside"),  Comcast
     Darlington  Limited  ("Comcast  Darlington")  or  Cambridge  Cable  Limited
     ("Cambridge  Cable") has any outstanding  liability to pay compensation for
     loss of office or  employment  to any  present  or former  employee  or any
     payment under the provisions of the Employment  Rights Act 1996 which would
     have a material adverse effect on Partners.

          (iv)  There are no terms of  employment  for any  employee  of Comcast
     Teesside, Comcast Darlington or Cambridge Cable which provide that a change
     in control of any Comcast Teesside,  Comcast  Darlington or Cambridge Cable
     (however  change of control  may be defined  if at all) shall  entitle  the
     employee  to treat  the  change  of  control  as  amounting  to a breach of
     contract or entitling him to any payment or benefit whatsoever or entitling
     him to treat  himself as redundant or otherwise  dismissed or released from
     any obligation.

          (v) None of Comcast Teesside, Comcast Darlington or Cambridge Cable is
     a party to any collective agreement,  dismissal procedures agreement, union
     membership  agreement,  or trade  dispute  (within the meaning of the Trade
     Union and Labour Relations (Consolidation) Act 1992) which would reasonably
     be expected to have a material adverse effect on Partners.

          (vi) "Schemes" means all and each of the pension schemes identified in
     the Section 3.1(i) of


                                       23
<PAGE>


     the  Partners  Disclosure  Schedule,   and  "Scheme  Documents"  means  the
     documents  relating  to the  Schemes  identified  in Section  3.1(i) of the
     Partners  Disclosure  Schedule,  which documents  comprise all the material
     documents  governing the Schemes.  Except pursuant to the Schemes,  Comcast
     Teesside, Comcast Darlington and Cambridge Cable have not paid, provided or
     contributed  towards  and are not  under  any  obligation  (whether  or not
     legally  enforceable)  to pay,  provide or  contribute  towards and are not
     under any obligation  (whether or not legally  enforceable) to pay, provide
     or  contribute  towards any  retirement/death/disability  benefit for or in
     respect of any present or past employee (or any spouse,  child or dependant
     of any of them) of Comcast Teesside, Comcast Darlington and Cambridge Cable
     which would  reasonably  be expected to have a material  adverse  effect on
     Partners. The Schemes are approved by the Board of the Inland Revenue as an
     exempt approved Scheme (within the meaning of Section 592, Income Taxes and
     Corporation Act 1988).

     (j) Taxes. (i) Each of Partners and its subsidiaries has filed all material
tax  returns and  reports  required  to be filed by it and all such  returns and
reports are  complete  and correct in all  material  respects,  or requests  for
extensions to file such returns or reports have been timely  filed,  granted and
have not  expired,  except to the  extent  that  such  failures  to file,  to be
complete  or  correct  or to have  extensions  granted  that  remain  in  effect
individually  or in the aggregate  would not have a material  adverse  effect on
Partners.  Partners and each of its  subsidiaries has paid (or Partners has paid
on its behalf) all taxes (as defined  herein) shown as due on such returns,  and
the most  recent  financial  statements  contained  in the  Partners  Filed  SEC
Documents  reflect an  adequate  reserve in  accordance  with GAAP for all taxes
payable by Partners and its  subsidiaries  for all taxable  periods and portions
thereof accrued through the date of such financial statements.

          (ii) No  deficiencies  for any taxes have been  proposed,  asserted or
     assessed  against  Partners  or  any  of  its  subsidiaries  that  are  not
     adequately  reserved for, except for deficiencies  that  individually or in
     the  aggregate  would  not have a  material  adverse  effect  on  Partners.
     Partners  has  never  been

          (iii)  As  used in  this  Agreement,  "taxes"  shall  include  all (x)
     national,  state, provincial or local income,  property,  sales, excise and
     other  taxes or  similar  governmental  charges,  including  any  interest,
     penalties or additions with respect thereto,  (y) liability for the payment
     of any amounts of the type  described  in (x) as a result of being a member
     of  an  affiliated,  consolidated,  combined  or  unitary  group,  and  (z)
     liability  for the payment of any amounts as a result of being party to any
     tax sharing  agreement or as a result of any express or implied  obligation
     to indemnify any other person with respect to the payment of any amounts of
     the type described in clause (x) or (y).

     (k) Voting Requirements.  The affirmative vote at the Partners Stockholders
Meeting (the  "Partners  Stockholder  Approval") of the holders of a majority of
the total  votes able to be cast at general  meetings  of Partners to adopt this
Agreement  is the only vote of the holders of any class or series of  Partners's
capital stock necessary to approve and adopt this Agreement and the transactions
contemplated hereby, including the Amalgamation.

     (l)  Brokers.  No broker,  investment  banker,  financial  advisor or other
person other than HSBC  Investment Bank plc, the fees and expenses of which will
be paid by Partners, is entitled to any broker's,  finder's, financial advisor's
or  other  similar  fee  or  commission  in  connection  with  the  transactions
contemplated by this Agreement based upon  arrangements  made by or on behalf of
Partners.

     (m) Opinion of Financial Advisor. Partners has received the opinion of HSBC
Investment Bank plc dated the date of this Agreement,  to the effect that, as of
such date, the Amalgamation Consideration is fair from a financial point of view
to holders of shares of Partners  Class A Common  Stock  (other than NTL and its
affiliates),  a signed copy of which opinion has been delivered to NTL, it being
understood  and agreed by NTL that such  opinion is for the benefit of the Board
of Directors of


                                       25
<PAGE>


Partners  and may not be  relied  upon by NTL,  its  affiliates  or any of their
respective stockholders.

     (n)  Intellectual  Property.  Partners and its  subsidiaries  own or have a
valid license to use all  trademarks,  service marks,  trade names,  patents and
copyrights  (including any registrations or applications for registration of any
of the foregoing) (collectively, the "Partners Intellectual Property") necessary
to carry on its business  substantially as currently conducted,  except for such
Partners  Intellectual  Property the failure of which to own or validly  license
individually  or in the aggregate  would not have a material  adverse  effect on
Partners.  Neither  Partners nor any such  subsidiary has received any notice of
infringement  of or conflict with,  and, to Partners's  knowledge,  there are no
infringements  of or conflicts (i) with the rights of others with respect to the
use of, or (ii) by others with  respect to, any Partners  Intellectual  Property
that  individually  or in the  aggregate,  in either  such  case,  would  have a
material adverse effect on Partners.

     (o)  Certain  Contracts.  Except  as set  forth in  Section  3.1(o)  of the
Partners Disclosure  Schedule,  (A) neither Partners nor any of its subsidiaries
is a party to or bound by (i) any  "material  contract" (as such term is defined
in Item  601(b)(10)  of  Regulation  S-K of the SEC),  (ii) any  non-competition
agreement or any other  agreement or obligation  which  purports to limit in any
material  respect the manner in which,  or the  localities in which,  all or any
material  portion of the business of Partners and its  subsidiaries  (including,
for  purposes of this Section  3.1(s),  NTL and its  subsidiaries,  assuming the
Amalgamation has taken place), taken as a whole, is or would be conducted, (iii)
any agreement between Partners or any Partners subsidiary,  on the one hand, and
any Significant Affiliate, on the other, or (iv) any contract or other agreement
which would prohibit or materially delay the consummation of the Amalgamation or
any of the transactions contemplated by this Agreement and (B) none of Partners,
any  subsidiary  of  Partners  or any  Significant  Affiliate  is subject to any
agreements  related to indebtedness for borrowed money ("Debt  Agreements") (all
contracts of the type described in clauses  (A)(i),  (ii) and (iii) and all Debt
Agreements  being  referred to herein as "Partners  Material  Contracts").  Each
Partners Material Contract is valid and binding on Partners (or,


                                       26
<PAGE>


to the extent a Partners  subsidiary or Significant  Affiliate is a party,  such
entity)  and is in full  force  and  effect,  and  Partners  and  each  Partners
subsidiary and Significant Affiliate have in all material respects performed all
obligations  required  to be  performed  by  them to date  under  each  Partners
Material  Contract,  except  where such  noncompliance,  individually  or in the
aggregate,  would not have a material  adverse  effect on Partners  and provided
that (except as to Debt  Agreements)  any  representation  in this sentence with
respect to a  Significant  Affiliate is qualified to the  knowledge of Partners.
Neither  Partners nor any Partners  subsidiary  knows of, or has received notice
of, any  violation or default  under (nor,  to the  knowledge of Partners,  does
there exist any condition which with the passage of time or the giving of notice
or both would result in such a violation or default under) any Partners Material
Contract.

the NTL SEC  Documents  (as  defined in  Section  3.2(e)) or as set forth on the
Disclosure  Schedule delivered by NTL to Partners prior to the execution of this
Agreement (the "NTL Disclosure Schedule") and making reference to the particular
subsection of this Agreement to which  exception is being taken,  NTL represents

          (a)  Organization,  Standing and Corporate  Power. (i) Each of NTL and
     its  subsidiaries  (including  Sub) is a corporation  or other legal entity
     duly  organized,  validly  existing and in good  standing  (with respect to
     jurisdictions   which  recognize  such  concept)  under  the  laws  of  the
     jurisdiction  in which it is organized and has the  requisite  corporate or
     other power,  as the case may be, and authority to carry on its business as
     now being conducted,  except, as to subsidiaries,  for those  jurisdictions
     where  the  failure  to be so  organized,  existing  or  in  good  standing
     individually or in the aggregate  would not have a material  adverse effect
     on NTL. Each of NTL and its  subsidiaries  is duly qualified or licensed to
     do business and is in good standing  (with respect to  jurisdictions  which
     recognize  such  concept) in each  jurisdiction  in which the nature of its
     business or the  ownership,  leasing or operation of its  properties  makes
     such qualification or licensing  necessary,  except for those jurisdictions


                                       27

     where the failure to be so qualified or licensed or to be in good  standing
     individually or in the aggregate  would not have a material  adverse effect
     on NTL.

          (ii) NTL has  delivered  to Partners  prior to the  execution  of this
     Agreement  complete and correct copies of its certificate of  incorporation
     and by-laws, as amended to date.

     (b)  Subsidiaries.  Exhibit 21 to NTL's Annual  Report on Form 10-K for the
fiscal year ended December 31, 1996 includes all the  subsidiaries  of NTL which
as of  the  date  of  this  Agreement  are  Significant  Subsidiaries.  All  the
outstanding  shares of capital stock of, or other equity interests in, each such
Significant  Subsidiary  have  been  validly  issued  and  are  fully  paid  and
nonassessable and are owned directly or indirectly by NTL, free and clear of all
Liens and free of any other restriction  (including any restriction on the right
to vote,  sell or  otherwise  dispose of such capital  stock or other  ownership
interests).

     (c) Capital  Structure.  The  authorized  capital  stock of NTL consists of
100,000,000  shares of NTL Common Stock and 2,500,000 shares of preferred stock,
par value  $.01 per  share,  of NTL  ("NTL  Preferred  Stock").  At the close of

complete and correct  list,  as of January 30, 1998,  of the number of shares of
NTL Common Stock  subject to employee  stock options or other rights to purchase

All outstanding  shares of capital stock of NTL are, and all shares which may be
issued  pursuant to this  Agreement  or  otherwise  will be, when  issued,  duly
authorized,  validly  issued,  fully paid and  nonassessable  and not subject to
preemptive  rights.  Except as set forth in this  Section  3.2(c) and except for
changes  since  January 28, 1998  resulting  from the  issuance of shares of NTL
Common  Stock  pursuant  to  the  conversion  or  exercise  of  NTL  Convertible

(x) there are not issued, reserved for issuance or outstanding (A) any shares of
capital stock or other voting  securities  of NTL, (B) any  securities of NTL or
any NTL subsidiary convertible into or exchangeable or exercisable for shares of
capital stock or voting securities of NTL, (C) any warrants,  calls,  options or
other rights to acquire from NTL or any NTL  subsidiary,  and any  obligation of
NTL or any NTL  subsidiary to issue,  any capital  stock,  voting  securities or
securities  convertible into or exchangeable or exercisable for capital stock or
voting securities of NTL, and (y) there are no outstanding obligations of NTL or
any  NTL  subsidiary  to  repurchase,  redeem  or  otherwise  acquire  any  such
securities  or to issue,  deliver or sell,  or cause to be issued,  delivered or
sold, any such securities.  As of the date hereof,  there are no outstanding (A)

exercisable for shares of capital stock or other voting  securities or ownership
interests in any NTL subsidiary, (B) warrants, calls, options or other rights to

subsidiary or (C) obligations of NTL or any NTL subsidiary to repur-


                                       29

chase,  redeem or  otherwise  acquire  any such  outstanding  securities  of NTL
subsidiaries or to issue,  deliver or sell, or cause to be issued,  delivered or
sold, any such securities.

     (d)  Authority;  Noncontravention.  NTL and  Sub  each  has  all  requisite
corporate  power and authority to enter into this Agreement and,  subject to the
NTL  Stockholder  Approval (as defined in Section  3.2(l)),  to  consummate  the
transactions  contemplated by this Agreement. The execution and delivery of this
Agreement by each of NTL and Sub and the  consummation by each of NTL and Sub of
the transactions contemplated by this Agreement have been duly authorized by all
necessary  corporate action on the part of NTL and Sub, subject,  in the case of
the  Amalgamation  and the issuance of NTL Common Stock in  connection  with the
Amalgamation,  to the NTL  Stockholder  Approval.  This  Agreement has been duly
executed  and  delivered  by  each  of  NTL  and  Sub  and,   assuming  the  due
authorization,  execution and delivery by Partners, constitutes the legal, valid
and binding obligations of each of NTL and Sub,  enforceable against each of NTL
and Sub in  accordance  with its  terms,  except as such  enforceability  may be
limited by applicable  bankruptcy  and similar laws or by general  principles of
equity (whether  considered in a proceeding in equity or at law).  Except as set
forth in  Section  3.2(d) of the NTL  Disclosure  Schedule,  the  execution  and
delivery of this  Agreement do not,  and the  consummation  of the  transactions
contemplated  by this  Agreement  and  compliance  with the  provisions  of this
Agreement  will not,  conflict  with,  or result in any violation of, or default
(with or  without  notice or lapse of time,  or both)  under,  or give rise to a
right of termination,  cancellation or acceleration of any obligation or loss of
a  benefit  under,  or  result  in the  creation  of any  Lien  upon  any of the
properties or assets of NTL or any of its  subsidiaries  (including  Sub) under,
(i)  the  certificate  of  incorporation  or  by-laws  of NTL or the  comparable
organizational  documents of any of its  subsidiaries  (including Sub), (ii) any
loan or  credit  agreement,  note,  bond,  mortgage,  indenture,  lease or other
agreement,  instrument,  permit,  concession,   franchise,  license  or  similar
authorization  applicable to NTL or any of its  subsidiaries  (including Sub) or
their  respective  properties  or assets or (iii)  subject  to the  governmental
filings and other matters referred to in the following  sentence,  any judgment,
order, decree, statute, law,


                                       30
<PAGE>


ordinance,  rule  or  regulation  applicable  to NTL or any of its  subsidiaries
(including  Sub) or their  respective  properties or assets,  other than, in the
case of  clauses  (ii) and  (iii),  any such  conflicts,  violations,  defaults,
rights, losses or Liens that individually or in the aggregate would not (x) have
a material  adverse  effect on NTL or (y)  reasonably  be expected to impair the
ability of NTL to perform  its  obligations  under this  Agreement.  No consent,
approval,   order  or  authorization  of,  action  by,  or  in  respect  of,  or
registration, declaration or filing with, any Governmental Entity is required by
or with respect to NTL or any of its subsidiaries  (including Sub) in connection
with the execution  and delivery of this  Agreement by each of NTL or Sub or the
consummation by NTL and Sub of the transactions  contemplated by this Agreement,
except for (1) the filing with the SEC of (A) the Joint Proxy Statement relating
to the NTL  Stockholders  Meeting,  (B) the Form S-4 and (C) such reports  under
Section 13(a),  13(d),  15(d) or 16(a) of the Exchange Act as may be required in
connection  with  this  Agreement  and  the  transactions  contemplated  by this
Agreement;  (2) the consent of the Minister in connection with the  Amalgamation
and the registration of the Amalgamated  Company with the Registrar of Companies
in  Bermuda  in  accordance  with  the  Companies  Act;  (3) such  filings  with
Governmental Entities to satisfy the applicable requirements of state securities
or "blue sky" laws;  (4) such filings with and approvals of the NASDAQ to permit
the shares of NTL Capital  Stock that are to be issued in the  Amalgamation  and
under the Partners  Stock Plans to be approved for quotation on the NASDAQ;  (5)
the receipt of the Required British Approvals; and (6) such consents, approvals,
orders  or  authorizations   the  failure  of  which  to  be  made  or  obtained
individually or in the aggregate would not (x) have a material adverse effect on
NTL or (y)  reasonably  be  expected to impair the ability of NTL to perform its
obligations under this Agreement.

     (e) SEC  Documents;  Undisclosed  Liabilities.  NTL has filed all  required
registration statements, prospectuses, reports, schedules, forms, statements and
other  documents  (including  exhibits  and all other  information  incorporated
therein)  with the SEC since  January 1, 1996 (the "NTL SEC  Documents").  As of
their respective dates, the NTL SEC Documents  complied in all material respects
with the requirements of the Securities Act or the Exchange Act, as the case may
be, and the rules


                                       31
<PAGE>


and  regulations of the SEC  promulgated  thereunder  applicable to such NTL SEC
Documents,  and none of the NTL SEC  Documents  when filed  contained any untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under which they were made,  not  misleading.  The financial
statements  of NTL included in the NTL SEC  Documents  comply as to form,  as of
their  respective  dates of filing with the SEC, in all material  respects  with
applicable  accounting  requirements  and the published rules and regulations of
the SEC with  respect  thereto,  have  been  prepared  in  accordance  with GAAP
(except, in the case of unaudited  statements,  as permitted by Form 10-Q of the
SEC) applied on a consistent basis during the periods involved (except as may be
indicated in the notes  thereto) and fairly present the  consolidated  financial
position of NTL and its  consolidated  subsidiaries  as of the dates thereof and
the consolidated results of their operations and cash flows for the periods then
ended (subject,  in the case of unaudited  statements,  to normal year-end audit
adjustments).  Except (i) as reflected in such  financial  statements  or in the
notes thereto or (ii) for liabilities incurred in connection with this Agreement
or the transactions contemplated hereby, neither NTL nor any of its subsidiaries
has any  liabilities or obligations of any nature which,  individually or in the
aggregate, would have a material adverse effect on NTL.

     (f)  Information  Supplied.  None  of  the  information  supplied  or to be
supplied  in writing by NTL  specifically  for  inclusion  or  incorporation  by
reference in (i) the Form S-4 will,  at the time the Form S-4 becomes  effective
under the  Securities  Act,  contain any untrue  statement of a material fact or
omit to state any material  fact  required to be stated  therein or necessary to
make the  statements  therein not  misleading or (ii) the Joint Proxy  Statement
will, at the date it is first mailed to NTL's stockholders or at the time of the
NTL  Stockholders  Meeting,  contain any untrue  statement of a material fact or
omit to state any material  fact  required to be stated  therein or necessary in
order to make the statements  therein, in light of the circumstances under which
they are made, not  misleading.  The Form S-4 and the Joint Proxy Statement will
comply  as to  form  in all  material  respects  with  the  requirements  of the
Securities  Act and the Exchange Act and the rules and  regulations


                                       32
<PAGE>


thereunder,  except  that no  representation  or  warranty  is made by NTL  with
respect  to  statements  made or  incorporated  by  reference  therein  based on
information supplied by Partners  specifically for inclusion or incorporation by
reference in the Form S-4 or the Joint Proxy Statement.

     (g) Absence of Certain Changes or Events.  Except for liabilities  incurred
in connection with this Agreement or the transactions  contemplated  hereby, and
except as  permitted by Section  4.1(b),  since  December 31, 1996,  NTL and its
subsidiaries  have conducted  their  business only in the ordinary  course or as
disclosed  in any NTL SEC  Document  filed since such date and prior to the date
hereof,  and there has not been (i) any material adverse change in NTL, (ii) any
declaration,  setting  aside or payment of any  dividend  or other  distribution
(whether in cash, stock or property) with respect to any of NTL's capital stock,
(iii) any split,  combination or  reclassification of any of NTL's capital stock
or any issuance or the  authorization of any issuance of any other securities in
respect of, in lieu of or in  substitution  for shares of NTL's  capital  stock,
except for  issuances  of NTL Common  Stock upon  conversion  or exercise of NTL
Convertible  Securities or exercise of NTL Employee Stock Options, in each case,
awarded  prior to the date  hereof in  accordance  with their  present  terms or
issued pursuant to Section 4.1(b),  (iv) except as required by a change in GAAP,
any change in  accounting  methods,  principles  or practices by NTL  materially
affecting  its  assets,  liabilities  or  business,  (v) any tax  election  that
individually or in the aggregate would have a material  adverse effect on NTL or
any of its tax attributes or any settlement or compromise of any material income
tax  liability  or (vi) any action  taken by NTL or any of the NTL  subsidiaries
during the period  from  December  31, 1996  through the date of this  Agreement
that,  if taken  during the period from the date of this  Agreement  through the
Effective Time would constitute a breach of Section 4.1(b).

          (h)  Compliance  with  Applicable  Laws;  Litigation.   (i)  NTL,  its
     subsidiaries   and  employees  hold  all  permits,   licenses,   variances,
     exemptions,   orders,  registrations  and  approvals  of  all  Governmental
     Entities  which are required for the operation of the businesses of NTL and
     its subsidiaries (the "NTL Permits"),  except where the failure to have any


                                       33
<PAGE>


     such NTL Permits individually or in the aggregate would not have a material
     adverse effect on NTL. NTL and its  subsidiaries are in compliance with the
     terms of the NTL Permits and all  applicable  statutes,  laws,  ordinances,
     rules and regulations,  except where the failure so to comply  individually
     or in the aggregate would not have a material  adverse effect on NTL. As of
     the date of this Agreement, no action, demand, requirement or investigation
     by any Governmental Entity and no suit, action or proceeding by any person,
     in each case with respect to NTL or any of its subsidiaries or any of their
     respective properties,  is pending or, to the knowledge of NTL, threatened,
     other than, in each case, those the outcome of which individually or in the
     aggregate  would  not (A)  have a  material  adverse  effect  on NTL or (B)
     reasonably  be expected to impair in any material way the ability of NTL to
     perform its obligations under this Agreement or prevent or materially delay
     the consummation of any of the transactions contemplated by this Agreement.

          (ii) Neither NTL nor any NTL subsidiary is subject to any  outstanding
     order,  injunction or decree which has had or, insofar as can be reasonably
     foreseen,  individually  or in the aggregate  will have a material  adverse
     effect on NTL.

     (i) Absence of Changes in Benefit Plans. Since December 31, 1996, there has
not been any adoption or amendment in any material  respect by NTL or any of its
subsidiaries  of any  collective  bargaining  agreement or any  material  bonus,
pension, profit sharing,  deferred compensation,  incentive compensation,  stock
ownership,  stock purchase, stock option, phantom stock,  retirement,  vacation,
severance,  disability, death benefit,  hospitalization,  medical or other plan,
arrangement  or  understanding  providing  benefits  to any  current  or  former
employee,  officer or  director of NTL or any of its wholly  owned  subsidiaries
(collectively, the "NTL Benefit Plans"), or any material change in any actuarial
or other  assumption used to calculate  funding  obligations with respect to any
NTL pension plans, or any material  change in the manner in which  contributions
to any NTL pension plans are made or the basis on which such  contributions  are
determined.


                                       34
<PAGE>


          (j) ERISA  Compliance.  (i) With respect to the NTL Benefit Plans,  no
     event has occurred and, to the knowledge of NTL,  there exists no condition
     or  set  of  circumstances,  in  connection  with  which  NTL or any of its
     subsidiaries  could be subject to any liability that individually or in the
     aggregate would have a material adverse affect on NTL under ERISA, the Code
     or any other applicable law.

          (ii)  Neither  NTL  nor  any  of its  subsidiaries  has  incurred  any
     unsatisfied  liability  under Title IV of ERISA (other than  liability  for
     premiums  to  the  Pension  Benefit  Guaranty  Corporation  arising  in the
     ordinary course). No NTL Benefit Plan has incurred an "accumulated  funding
     deficiency"  (within  the meaning of Section 302 of ERISA or Section 412 of
     the Code) whether or not waived. To the knowledge of NTL, there are not any
     facts or circumstances  that would  materially  change the funded status of
     any NTL  Benefit  Plan that is a  "defined  benefit"  plan (as  defined  in
     Section 3(35) of ERISA) since the date of the most recent  actuarial report
     for such plan.  No NTL Benefit  Plan is a  "multiemployer  plan" within the
     meaning of Section 3(37) of ERISA.

          (k) Taxes. (i) Each of NTL and its subsidiaries has filed all material
     tax returns and reports required to be filed by it and all such returns and
     reports are complete and correct in all material respects,  or requests for
     extensions to file such returns or reports have been timely filed,  granted
     and have not expired,  except to the extent that such  failures to file, to
     be complete or correct or to have extensions  granted that remain in effect
     individually or in the aggregate  would not have a material  adverse effect
     on NTL. NTL and each of its  subsidiaries  has paid (or NTL has paid on its
     behalf)  all  taxes  shown  as due on such  returns,  and the  most  recent
     financial statements contained in the NTL SEC Documents reflect an adequate
     reserve  in  accordance  with  GAAP for all  taxes  payable  by NTL and its
     subsidiaries  for all taxable periods and portions  thereof accrued through
     the date of such financial statements.

          (ii) No  deficiencies  for any taxes have been  proposed,  asserted or
     assessed against NTL or


                                       35
<PAGE>


     any of its  subsidiaries  that are not adequately  reserved for, except for
     deficiencies  that  individually  or in  the  aggregate  would  not  have a
     material  adverse  effect on NTL. The federal income tax returns of NTL and
     each of its subsidiaries consolidated in such returns for tax years through
     1992 have closed by virtue of the applicable statute of limitations.

     (l)  Voting  Requirements.  The  affirmative  vote at the NTL  Stockholders
Meeting  (the "NTL  Stockholder  Approval")  of the holders of a majority of all
shares of NTL Common Stock  casting votes is the only vote of the holders of any
class or series of NTL's capital stock necessary to approve,  in accordance with
the applicable rules of the NASDAQ, the issuance of NTL Common Stock pursuant to
the Amalgamation.
 
     (m)  Brokers.  No broker,  investment  banker,  financial  advisor or other
person, other than Donaldson, Lufkin & Jenrette Securities Corporation, the fees
and  expenses  of  which  will  be paid by NTL,  is  entitled  to any  broker's,
finder's,  financial  advisor's or other similar fee or commission in connection
with the  transactions  contemplated by this Agreement  based upon  arrangements
made by or on behalf of NTL.

     (n)  Opinion  of  Financial  Advisor.  NTL  has  received  the  opinion  of
Donaldson,  Lufkin &  Jenrette  Securities  Corporation,  dated the date of this
Agreement,  to the effect that, as of such date,  the Exchange  Ratio is fair to
NTL from a  financial  point of view,  a signed  copy of which  opinion has been
delivered  to Partners,  it being  understood  and agreed by Partners  that such
opinion  is for the  benefit  of the  Board of  Directors  of NTL and may not be
relied upon by Partners, its affiliates or any of their respective stockholders.

Agreement  to  the  Effective  Time,   Partners  shall,   and  shall  cause  its

reasonable  efforts to keep available the services of their current officers and
other key employees and preserve their  relationships  with those persons having
business  dealings with them.  Without  limiting the generality of the foregoing
(but subject to the above  exceptions),  during the period from the date of this
Agreement to the Effective Time, Partners shall not, and shall not permit any of
its subsidiaries to:

          (i) other than  dividends  and  distributions  by a direct or indirect
     wholly owned subsidiary of Partners to its parent,  or by a subsidiary that
     is partially  owned by Partners or any of its  subsidiaries,  provided that
     Partners or any such subsidiary receives or is to receive its proportionate
     share  thereof,  (x) declare,  set aside or pay any  dividends on, make any
     other distributions in respect of, or enter into any agreement with respect
     to  the  voting  of,  any of its  capital  stock,  (y)  split,  combine  or
     reclassify  any of its capital  stock or issue or authorize the issuance of

     Partners or any of its subsidiaries or any other securities  thereof or any
     rights, warrants or options to acquire any such shares or other securities;

          (ii) issue, deliver,  sell, pledge or otherwise encumber or subject to
     any Lien any shares of its capital  stock,  any other voting  securities or
     any  securities  convertible  into,  or any rights,  warrants or options to
     acquire,  any such shares,  voting  securities  or  convertible  securities
     (other


                                       37
<PAGE>


     than the  issuance of Partners  Common  Stock upon the exercise of Partners
     Employee Stock Options, in each case,  outstanding as of the date hereof in
     accordance with their present terms;

          (iii)  amend  its  memorandum  of   association,   bye-laws  or  other
     comparable organizational documents;

          (iv) acquire or agree to acquire by merging or consolidating  with, or
     by  purchasing  a  substantial  portion  of the  assets of, or by any other

          (v) subject to compliance  with Section 5.15,  sell,  lease,  license,
     mortgage or otherwise  encumber or subject to any Lien or otherwise dispose
     of any of its properties or assets (including securitizations),  other than
     (A) in the ordinary course of business consistent with past practice or (B)
     the sale,  lease,  license or other disposition of up to $1 million of such
     assets, in the aggregate or (C) the mortgage,  encumbrance or subjecting to
     Liens of up to $5 million of such assets, in the aggregate;

          (vi)  take  any  action  that  would  cause  the  representations  and
     warranties  set forth in Section  3.1(g)  (with each  reference  therein to
     "ordinary  course of  business"  being  deemed for purposes of this Section
     4.1(a)(vi) to be immediately  followed by "consistent  with past practice")
     to no longer be true and correct;

          (vii) incur any indebtedness  for borrowed money,  other than pursuant
     to agreements or arrangements in effect as of the date hereof, or issue any
     debt  securities  or assume,  guarantee  or  endorse,  or  otherwise  as an
     accommodation  become  responsible  for the  obligations  of any person for
     borrowed money;

          (viii) make any additional equity investment in, or enter into any new
     agreement, arrangement or understanding with, any Significant Affiliate; or


                                       38
<PAGE>


          (ix)  authorize,  or  commit  or agree to take,  any of the  foregoing
     actions;

provided  that the  limitations  set forth in this  Section  4.1(a)  (other than
clause (iii)) shall not apply to any transaction between Partners and any wholly
owned subsidiary or between any wholly owned subsidiaries of Partners. Except as
set forth in Section 4.1(a) of the Partners Disclosure Schedule,  Partners shall
not, and shall not permit its subsidiaries to, and shall use its reasonable best
efforts to cause its  Significant  Affiliates  not to,  enter into any  material
agreement,  arrangement or understanding with respect to programming;  software;
provisioning of cable modem internet service;  billing;  provisioning of digital
CATV service;  and the  acquisition  of set-top boxes or switching  equipment or
other  computer  and  telecommunications  equipment  with a value in excess of 1
million (pound  sterling);  or technology or similar  strategic  business issues
without prior approval from NTL. NTL shall treat as confidential any information
which  Partners  discloses to NTL in respect of any  Significant  Affiliate  and
designates as confidential.

     (b) Conduct of Business  by NTL.  Except as set forth in Section  4.1(b) of
the  NTL  Disclosure  Schedule,  as  otherwise  expressly  contemplated  by this
Agreement  or as  consented  to by Partners in writing,  such  consent not to be
unreasonably  withheld  or  delayed,  during  the  period  from the date of this
Agreement to the Effective Time, NTL shall, and shall cause its subsidiaries to,
carry on their respective businesses in the ordinary course consistent with past
practice and, to the extent consistent therewith,  use all reasonable efforts to
preserve intact their current business organizations,  use reasonable efforts to
keep  available the services of their  current  officers and other key employees
and preserve their  relationships  with those persons having  business  dealings
with them.  Without limiting the generality of the foregoing (but subject to the
above  exceptions),  during the period  from the date of this  Agreement  to the
Effective Time, NTL shall not, and shall not permit any of its subsidiaries to:

          (i) other than  dividends  and  distributions  by a direct or indirect
     wholly owned  subsidiary of NTL to its parent,  or by a subsidiary  that is
     partially owned by NTL or any of its subsidiar-


                                       39
<PAGE>


     ies, provided that NTL or any such subsidiary receives or is to receive its
     proportionate  share thereof,  declare,  set aside or pay any dividends on,
     make any other distributions (whether by recapitalization, restructuring or
     otherwise) in respect of, or enter into any  agreement  with respect to the
     voting of,  any of its  capital  stock,  other  than  reasonable  quarterly
     dividends  on NTL Common  Stock if the Board of  Directors  of NTL shall so
     determine;

          (ii) adopt a plan of complete or partial liquidation;

          (iii) enter into any  agreement,  arrangement or  understanding  for a
     merger,  acquisition  or other  business  combination  unless  the Board of
     Directors of NTL determines  that such  transaction is in the best interest
     of the  stockholders of NTL and those persons who will become  stockholders
     of NTL as a result of the Amalgamation;

          (iv) except as  contemplated  hereby  (including in connection  with a
     transaction   permitted  by  clause  (iii)),   amend  its   certificate  of
     incorporation; or

          (v)  authorize,  or  commit  or agree to  take,  any of the  foregoing
     actions;

provided that the  limitations  set forth in this Section 4.1(b) shall not apply
to any  transaction  between NTL and any wholly owned  subsidiary or between any
wholly owned subsidiaries of NTL.

     (c) Other Actions.  Except as required by law,  Partners and NTL shall not,
and shall not permit any of their respective  subsidiaries to,  voluntarily take
any action that would,  or that could  reasonably  be expected to, result in (i)
any of the  representations  and  warranties  of such  party  set  forth in this
Agreement that are qualified as to materiality  becoming untrue at the Effective
Time, (ii) any of such  representations and warranties that are not so qualified
becoming  untrue in any material  respect at the Effective Time, or (iii) any of
the conditions to the Amalgamation set forth in Article VI not being satisfied.


                                       40
<PAGE>


     (d) Advice of Changes.  Partners  and NTL shall  promptly  advise the other
party  orally  and  in  writing  to  the  extent  it has  knowledge  of (i)  any
representation  or  warranty  made by it  contained  in this  Agreement  that is
qualified as to materiality  becoming untrue or inaccurate in any respect or any
such  representation  or warranty  that is not so qualified  becoming  untrue or
inaccurate  in any  material  respect,  (ii) the  failure by it to comply in any
material respect with or satisfy in any material respect any covenant, condition
or agreement to be complied  with or  satisfied by it under this  Agreement  and
(iii) any  change  or event  having,  or which,  insofar  as can  reasonably  be
foreseen, could reasonably be expected to have a material adverse effect on such
party or on the truth of their respective  representations and warranties or the
ability of the  conditions  set forth in Article VI to be  satisfied;  provided,
however, that no such notification shall affect the representations, warranties,
covenants or agreements of the parties (or remedies with respect thereto) or the
conditions to the obligations of the parties under this Agreement.

     SECTION 4.2 No Solicitation by Partners.  (a) Partners shall not, nor shall
it permit any of its  subsidiaries  to, nor shall it  authorize or permit any of
its  directors,  officers  or  employees  or any  investment  banker,  financial
advisor,  attorney,  accountant or other representative retained by it or any of
its subsidiaries to, directly or indirectly through another person, (i) solicit,
initiate or  encourage  or take any other  action  designed to  facilitate,  any
inquiries or the making of any proposal which  constitutes any Partners Takeover
Proposal  (as  defined  below)  or  (ii)   participate  in  any  discussions  or
negotiations  regarding any Partners  Takeover Proposal or furnish any nonpublic
information  relating to Partners and its subsidiaries to any person that may be
considering  making, or has made, a Partners Takeover  Proposal;  provided that,
Partners may, in response to an unsolicited  written proposal from a third party
regarding a Partners Takeover  Proposal,  engage in the activities  specified in
clause (ii) if (A) the Board of Directors of Partners  determined in good faith,
after obtaining and taking into account the advice of outside counsel, that such
action is  required  for the Board of  Directors  to comply  with its  fiduciary
duties under  applicable law and (B) Partners has received from such third party
an executed  confidentiality  agreement with 


                                       41
<PAGE>


terms  not  materially  less  favorable  to  NTL  than  those  contained  in the
Confidentiality  Agreement  (as defined in Section  5.4).  For  purposes of this
Agreement,  "Partners  Takeover  Proposal" means any inquiry,  proposal or offer
from any person relating to any direct or indirect  acquisition or purchase of a
business that  constitutes  10% or more of the net  revenues,  net income or the
assets of Partners and its subsidiaries,  taken as a whole, or 10% or any equity
securities of Partners,  any tender offer or exchange  offer that if consummated
would  result  in any  person  beneficially  owning  any  equity  securities  of
Partners, or any merger, consolidation, business combination,  recapitalization,
liquidation,  dissolution  or similar  transaction  involving  Partners  (or any
Partners subsidiary whose business  constitutes 10% or more of the net revenues,
net income or the assets of Partners  and its  subsidiaries,  taken as whole) or
the Partners  Common Stock,  other than the  transactions  contemplated  by this
Agreement;  provided  that  Partners  Takeover  Proposal  shall not  include any
matters  relating  to the Rights of First  Refusal and the equity  interests  of
Partners subject thereto.

     (b) Except as  provided in the next  sentence,  the Board of  Directors  of
Partners  shall  recommend  approval  and  adoption  of this  Agreement  and the
Amalgamation  by Partners's  stockholders  and shall not withdraw or modify,  or
propose publicly to withdraw or modify, in a manner adverse to NTL, the approval
or recommendation by such Board of Directors. The Board of Directors of Partners
shall be permitted to withdraw or modify in a manner  adverse to NTL (or, if not
previously made, not to make) its recommendation to Partners's stockholders, but
only if and to the extent such Board of Directors  determines,  after  obtaining
and taking  into  account  the advice of outside  counsel,  that such  action is
required in response  to an  unsolicited  bona fide  written  Superior  Partners
Takeover  Proposal  in order for such  Board of  Directors  to  comply  with its
fiduciary duties under applicable law.  "Superior  Partners  Takeover  Proposal"
means any bona fide  Partners  Takeover  Proposal for at least a majority of the
outstanding  shares of Partners  Common Stock on terms the Board of Directors of
Partners  determines in its good faith judgment (taking in to account the advice
of its  financial  advisor,  all of the terms and  conditions  of such  Partners
Takeover  Proposal and the  conditions to  consummation)  are more favorable


                                       42
<PAGE>


and provide  greater  value to Partners  and all of its  stockholders  than this
Agreement and the Amalgamation taken as a whole.

     (c) In addition to the  obligations of Partners set forth in paragraphs (a)
and (b) of this Section 4.2, Partners shall immediately advise NTL orally and in
writing of any request for information or of any Partners Takeover Proposal, the
material terms and conditions of such request or Partners  Takeover Proposal and
the identity of the person  making such request or Partners  Takeover  Proposal.
Partners will, to the extent  consistent with the fiduciary  duties of its Board
of Directors under  applicable  law, keep NTL reasonably  informed of the status
and details (including amendments or proposed amendments) of any such request or
Partners Takeover Proposal.

     (d) Nothing  contained in this  Section 4.2 shall  prohibit  Partners  from
taking  and  disclosing  to its  stockholders  a position  contemplated  by Rule
14e-2(a)  promulgated  under the Exchange Act or from making any  disclosure  to
Partners's stockholders if, in the good faith judgment of the Board of Directors
of Partners,  after  consultation  with outside counsel,  failure so to disclose
would be inconsistent with its obligations under applicable law.

                              ADDITIONAL AGREEMENTS

     SECTION  5.1.  Preparation  of the Form S-4 and the Joint Proxy  Statement;
Stockholders  Meetings.  (a) As soon as  practicable  following the date of this
Agreement,  Partners and NTL shall prepare and file with the SEC the Joint Proxy
Statement and NTL shall prepare and file with the SEC the Form S-4, in which the
Joint Proxy Statement will be included as a prospectus. Each of Partners and NTL
shall  use  best  efforts  to have the Form S-4  declared  effective  under  the
Securities Act as promptly as 


                                       43
<PAGE>


practicable  after such filing.  Partners will use all best efforts to cause the
Joint Proxy Statement to be mailed to Partners's stockholders,  and NTL will use
all best  efforts  to cause  the  Joint  Proxy  Statement  to be mailed to NTL's
stockholders,  in each case as  promptly  as  practicable  after the Form S-4 is
declared  effective  under the  Securities  Act.  NTL shall also take any action
(other than qualifying to do business in any jurisdiction in which it is not now
so qualified or to file a general consent to service of process)  required to be
taken under any applicable state securities laws in connection with the issuance
of NTL  Capital  Stock  in the  Amalgamation  and  Partners  shall  furnish  all
information  concerning Partners and the holders of Partners Common Stock as may
be  reasonably  requested in connection  with any such action.  No filing of, or
amendment or supplement  to, the Form S-4 or the Joint Proxy  Statement  will be
made by NTL  without  the prior  consent of  Partners,  such  consent  not to be
unreasonably  withhold or delayed.  NTL will advise Partners,  promptly after it
receives notice thereof,  of the time when the Form S-4 has become  effective or
any supplement or amendment has been filed,  the issuance of any stop order, the
suspension of the  qualification of the NTL Capital Stock issuable in connection
with the Amalgamation for offering or sale in any  jurisdiction,  or any request
by the SEC for  amendment  of the  Joint  Proxy  Statement  or the  Form  S-4 or
comments  thereon and  responses  thereto or requests by the SEC for  additional
information. If at any time prior to the Effective Time any information relating
to  Partners  or  NTL,  or any  of  their  respective  affiliates,  officers  or
directors,  should be discovered by Partners or NTL which should be set forth in
an amendment or supplement to any of the Form S-4 or the Joint Proxy  Statement,
so that any of such documents  would not include any  misstatement of a material
fact or omit to  state  any  material  fact  necessary  to make  the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading, the party which discovers such information shall promptly notify the
other parties hereto and an appropriate  amendment or supplement describing such
information  shall be promptly filed with the SEC and, to the extent required by
law, disseminated to the stockholders of Partners and NTL.

     (b) Partners shall duly call, give notice of, convene and hold a meeting of
its stockholders  (the "Partners  Stockholders  Meeting") in accordance with the
Companies Act and Partners's  bye-laws for the purpose of obtaining the Partners
Stockholder  Approval and, subject to Sections 4.2(b) and (d), through its Board
of Directors,  recommend to its  stockholders  the approval and


                                       44
<PAGE>


adoption  of this  Agreement  and the  Amalgamation.  Partners  agrees  that its
obligations  to convene  the  Partners  Stockholders  Meeting  pursuant  to this
Section  5.1(b)  shall not be affected  by the  commencement,  public  proposal,
public  disclosure  or  communication  to  Partners  of  any  Partners  Takeover
Proposal.

     (c) NTL shall,  as promptly as  practicable  after the Form S-4 is declared
effective  under the Securities Act, duly call, give notice of, convene and hold
a meeting of its  stockholders  (the "NTL  Stockholders  Meeting") in accordance
with the Delaware  General  Corporation Law for the purpose of obtaining the NTL
Stockholder Approval and shall, through its Board of Directors, recommend to its
stockholders  the  approval  and  adoption  of this  Agreement,  and  the  other
transactions  contemplated  hereby.  The Board of Directors of NTL or Sub or any
committee  thereof shall not withdraw or modify, or propose publicly to withdraw
or modify in a manner  adverse to Partners,  the approval or  recommendation  by
such Board of Directors or such committee of this Agreement and the transactions
contemplated hereby.

     (d)  NTL  and  Partners   will  use  best  efforts  to  hold  the  Partners
Stockholders  Meeting and the NTL  Stockholders  Meeting on the same date and as
soon as reasonably practicable after the date hereof.

     SECTION 5.2 Letters of Partners' Accountants. Partners shall use reasonable
efforts to cause to be delivered to NTL two letters from Partners's  independent
accountants,  one dated a date within two business days before the date on which
the Form S-4 shall  become  effective  and one dated a date within two  business
days before the  Closing  Date,  each  addressed  to NTL, in form and  substance
reasonably  satisfactory to NTL and customary in scope and substance for comfort
letters  delivered  by  independent   public   accountants  in  connection  with
registration statements similar to the Form S-4.

     SECTION 5.3 Letters of NTL's Accountants.  NTL shall use reasonable efforts
to  cause to be  delivered  to  Partners  two  letters  from  NTL's  independent
accountants,  one dated a date within two business days before the date on which
the Form S-4 shall  become  effective  and one dated a date within two  business
days before the Closing Date, each addressed to Partners,  in form and substance


                                       45
<PAGE>


reasonably  satisfactory  to Partners and  customary in scope and  substance for
comfort letters delivered by independent  public  accountants in connection with
registration statements similar to the Form S-4.

     SECTION  5.4  Access  to  Information;   Confidentiality.  Subject  to  the
Confidentiality  Agreement  dated March 10, 1997,  between NTL and Partners (the
"Confidentiality   Agreement"),   and  subject  to  restrictions   contained  in
confidentiality  or other  agreements to which such party is subject (which such
party will use its reasonable  efforts to have waived) and applicable  law, each
of Partners and NTL shall,  and shall cause each of its respective  subsidiaries
to,  afford to the  other  party and to the  officers,  employees,  accountants,
counsel,  financial  advisors  and other  representatives  of such other  party,
reasonable  access during normal  business  hours during the period prior to the
Effective  Time  to  all  their   respective   properties,   books,   contracts,
commitments, personnel and records and, during such period, each of Partners and
NTL shall,  and shall  cause each of its  respective  subsidiaries  to,  furnish
promptly to the other party (a) a copy of each  report,  schedule,  registration
statement  and other  document  filed by it during such  period  pursuant to the
requirements of federal or state  securities laws and (b) all other  information
concerning  its  business,  properties  and  personnel  as such other  party may
reasonably  request.  No review  pursuant to this  Section 5.4 shall  affect any
representation or warranty given by the other party hereto. Each of Partners and
NTL will hold, and will cause its respective officers,  employees,  accountants,
counsel,  financial advisors and other  representatives  and affiliates to hold,
any nonpublic  information in accordance  with the terms of the  Confidentiality
Agreement.

     SECTION 5.5 Reasonable Best Efforts.  (a) Upon the terms and subject to the
conditions  set  forth in this  Agreement,  each of the  parties  agrees  to use
reasonable best efforts to take, or cause to be taken,  all actions,  and to do,
or cause to be done,  and to assist  and  cooperate  with the other  parties  in
doing,  all  things  necessary,  proper  or  advisable  to  consummate  and make
effective, in the most expeditious manner practicable,  the Amalgamation and the
other transactions  contemplated by this Agreement,  including (i) the obtaining
of all necessary actions or nonactions, waivers, consents and


                                       46
<PAGE>


approvals   from   Governmental   Entities  and  the  making  of  all  necessary
registrations  and  filings and the taking of all steps as may be  necessary  to
obtain an approval or waiver from, or to avoid an action or  proceeding  by, any
Governmental Entity, (ii) the obtaining of all necessary consents,  approvals or
waivers from third  parties,  (iii) the defending of any lawsuits or other legal
proceedings,  whether judicial or administrative,  challenging this Agreement or
the consummation of the transactions  contemplated by this Agreement,  including
seeking to have any stay or temporary  restraining order entered by any court or
other  Governmental  Entity  vacated or  reversed,  and (iv) the  execution  and
delivery of any additional  instruments necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, this Agreement. Without
limitation  of the  foregoing,  Partners and NTL shall,  and shall cause each of
their  subsidiaries  to, and, in the case of Partners,  shall use its reasonable
best  efforts to cause its  Significant  Affiliates  to,  promptly  supply  such
information  as  is  reasonably   necessary  to  enable  the  confirmations  and
indications referred to in Section 6.1(c) to be obtained.

     (b) In connection with and without limiting the foregoing, Partners and NTL
shall (i) take all  action  necessary  to ensure  that no  takeover  statute  or
similar  statute or  regulation  (other than the U.K. City Code on Takeovers and
Mergers  in  relation  to  Cable  London)  is  or  becomes   applicable  to  the
Amalgamation,  this Agreement, or any of the other transactions  contemplated by
this Agreement and (ii) if any takeover statute or similar statute or regulation
becomes applicable to the Amalgamation, this Agreement, or any other transaction
contemplated  by this  Agreement,  take all action  necessary to ensure that the
Amalgamation  and the other  transactions  contemplated by this Agreement may be
consummated  as  promptly  as  practicable  on the  terms  contemplated  by this
Agreement  and otherwise to minimize the effect of such statute or regulation on
the Amalgamation and the other transactions contemplated by this Agreement.

     SECTION 5.6 Stock  Options and Stock  Appreciation  Rights.  (a) As soon as
practicable  following  the date of this  Agreement,  the Board of  Directors of
Partners (or, if  appropriate,  any committee  administering  the Partners Stock
Plan or Partners 1995 Stock  Appreciation  Rights Plan (the "Partners SAR Plan",
and together with


                                       47
<PAGE>


the Partners Stock Plan, the "Partners  Incentive Plans"),  if requested by NTL,
shall,  subject to the rights of the holders thereunder,  adopt such resolutions
or take such other actions as may be required to effect the following:

          (i)  adjust  the  terms of all  outstanding  Partners  Employee  Stock
     Options granted under Partners Stock Plan,  whether vested or unvested,  as
     necessary to provide that, at the Effective  Time,  each Partners  Employee
     Stock Option  outstanding  immediately prior to the Effective Time shall be
     adjusted and thereafter  represent an option to acquire,  on the same terms
     and  conditions  as were  applicable  under such  Partners  Employee  Stock
     Option,  the  number of shares of NTL Common  Stock  equal to the number of
     shares of Partners  Common  Stock  subject to the Partners  Employee  Stock
     Option,  multiplied by the Exchange  Ratio (such product  rounded up to the
     nearest whole  number),  at an exercise price per share of NTL Common Stock
     (rounded down to nearest  whole cent) equal to (A) the  aggregate  exercise
     price  for the  shares  of  Partners  Common  Stock  otherwise  purchasable
     pursuant  to  such  Partners  Employee  Stock  Option  divided  by (B)  the
     aggregate  number of whole  shares of NTL Common Stock deemed to be subject
     to such Partners  Employee  Stock Option in  accordance  with the foregoing
     (each, as so adjusted, an "Adjusted Option");

          (ii) adjust the terms of all outstanding  Partners stock  appreciation
     rights  (the  "Partners  SARs")  granted  under  the  Partners  SAR Plan as
     necessary  to provide  that,  at the  Effective  Time,  each  Partners  SAR
     outstanding  immediately  prior to the Effective Time shall be adjusted and
     thereafter  represent  a right to  receive  an amount of cash,  on the same
     terms and conditions as were  applicable  under such Partners SAR,  without
     regard to any  provision  reducing the period of exercise of such  Partners
     SAR pursuant to the  cessation of service as a director of Partners,  equal
     to the amount by which the Fair Market  Value (as  defined in the  Partners
     SAR Plan) per share of NTL Common Stock  multiplied  by the Exchange  Ratio
     (rounded to the nearest  cent) exceeds a base price per share of NTL Common
     Stock equal to the base price for the Partners Class A


                                       48
<PAGE>


     Common  share  subject to such  Partners  SAR  (each,  as so  adjusted,  an
     "Adjusted SAR"); and

          (iii) take such other actions relating to the Partners Incentive Plans
     as  Partners  and NTL may  agree  are  appropriate  to give  effect  to the
     Amalgamation, including as provided in Section 5.7.

     (b) As soon as practicable  after the Effective  Time, NTL shall deliver to
the holders of Partners  Employee  Stock Options and Partners  SARs  appropriate
notices setting forth such holders'  rights pursuant to the respective  Partners
Incentive Plan and the agreements evidencing the grants of awards thereunder and
that such awards and  agreements  shall be assumed by NTL and shall  continue in
effect on the same  terms and  conditions  (subject  to the  provisions  of this
Section  5.6,  including  adjustments  required by this Section 5.6 after giving
effect to the Amalgamation).

     (c) A holder  of an  Adjusted  Option or  Adjusted  SAR may  exercise  such
Adjusted Option or Adjusted SAR in whole or in part in accordance with its terms
by delivering a properly  executed notice of exercise to NTL,  together with the
consideration  therefor and the federal  withholding  tax  information,  if any,
required in accordance with the related Partners Incentive Plan.

     (d) Except as otherwise  contemplated by this Section 5.6 and except to the
extent  required  under the  respective  terms of the  Partners  Employee  Stock
Options and Partners SARs in effect as of the date hereof,  all  restrictions or
limitations  on transfer  and vesting with  respect to Partners  Employee  Stock
Options and Partners  SARs awarded  under the  Partners  Incentive  Plans or any
other plan,  program or arrangement of Partners or any of its  subsidiaries,  to
the extent that such  restrictions or limitations shall not have already lapsed,
shall  remain in full force and effect  with  respect to such  options  and SARs
after giving effect to the  Amalgamation  and the assumption by NTL as set forth
above.

     SECTION 5.7 Partners  Incentive Plans and Certain Employee Matters.  (a) At
the Effective  Time, the Partners  Incentive Plans shall be assumed by NTL, with
the result that all obligations of Partners under the Partners  Incentive Plans,
including  with respect to


                                       49
<PAGE>


awards  outstanding  at the Effective Time under each Partners  Incentive  Plan,
shall be obligations of NTL following the Effective Time. Prior to the Effective
Time,  NTL shall take all necessary  actions  (including,  if required to comply
with  Section  162(m) or 422 of the Code  (and the  regulations  thereunder)  or
applicable law or rule of the NASDAQ, obtaining the approval of its stockholders
at the NTL  Stockholders  Meeting) for the assumption of the Partners  Incentive
Plans, including the reservation,  issuance and quotation of NTL Common Stock in

attorneys'  fees),  judgments,  fines,  losses,  claims,  damages or liabilities
(collectively,  "Costs")  incurred in connection with any claim,  action,  suit,
proceeding  or  investigation,   whether  civil,  criminal,   administrative  or

Section 5.8.

     (c) For six years after the Effective Time, NTL shall provide to Partners's
current directors and officers  liability  insurance  covering acts or omissions
occurring  prior to the  Effective  Time with  respect to those  persons who are
currently covered by Comcast  Corporation's  directors' and officers'  liability
insurance  policy on terms  with  respect  to such  coverage  and amount no less
favorable than those of such policy in effect on the date hereof,  provided that
in no event shall NTL be required to expend more than  $360,000 in the aggregate
to maintain such coverage.

     (d) The  provisions  of this  Section  5.8 (i) are  intended  to be for the
benefit of, and will be enforceable by, each Indemnified Party, his or her heirs
and  his or  her  representatives  and  (ii)  are in  addition  to,  and  not in
substitution for, any other rights to  indemnification  or contribution that any
such person may have by contract or otherwise.  Each Indemnified Party is hereby
expressly  made a third  party  beneficiary  of the  provisions  in favor of the
Indemnified  Parties set forth in this Section 5.8. NTL will pay all  reasonable
Costs,  including attorney's fees, that may be incurred by any Indemnified Party
in enforcing the indemnity  and other  obligations  provided for in this Section

contemplated  herein to  determine  whether  tax  efficiencies  can be  achieved
without  affecting in any adverse manner the value of the transactions to NTL or
the stockholders of Partners or impairing the ability of the parties to complete
the  transactions  by the End Date. If such  efficiencies  are  identified,  the
parties will use  reasonable  best efforts to restructure  the  transaction in a
manner consistent therewith.

case,   without  the  prior  approval  of  NTL,  which  approval  shall  not  be
unreasonably withheld or delayed.

have,  individually  or in the  aggregate,  a material  adverse effect on NTL or
Partners.

     (b)  Performance of Obligations of Partners.  Partners shall have performed
in all material  respects


                                       59

failure  to use best  efforts  to  consummate  the  Amalgamation  and the  other
transactions  contemplated  by this  Agreement,  as  required  by and subject to

                                NTL INCORPORATED


             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware


     NTL  Incorporated,  a corporation  organized and existing under the General
Corporation  Law of the State of Delaware,  in accordance with the provisions of
Section 103 thereof, HEREBY CERTIFIES:

     That pursuant to the authority conferred upon the Board of Directors by the
Certificate  of  Incorporation  of the  said  Corporation,  the  said  Board  of
Directors on ______, 1998 adopted the following  resolution creating a series of
________________  shares  of  Preferred  Stock  designated  as  Class  C  Junior
Participating Preferred Stock:

     RESOLVED,  that pursuant to the authority  vested in the Board of Directors
of this  Corporation  in accordance  with the  provisions of its  Certificate of
Incorporation,  a series of Preferred  Stock of the Corporation be and it hereby
is created,  and that the  designation and amount thereof and the voting powers,
preferences  and relative,  participating,  optional and other special rights of
the shares of such series, and the  qualifications,  limitations or restrictions
thereof are as follows:

     1. Designation and Amount. The shares of such series shall be designated as
"Class C Junior  Participating  Preferred  Stock," par value $.01 per share (the
"Class C Junior Preferred Stock"),  and the number of shares constituting such
series shall be ____________.

     2. Dividends and Distributions.  (a) Each share of Class C Junior Preferred
Stock shall be entitled to


<PAGE>

 
receive,  when,  as and if  declared  by the  Board of  Directors,  out of funds
legally  available  for the  payment of  dividends,  contemporaneously  with any
dividends  with  respect to shares of Common  Stock (as defined in Section  11),
dividends in an amount per share (rounded to the nearest cent) equal to, subject
to the provision for adjustment hereinafter set forth, 1.00* times the aggregate
per share  amount of cash  dividends  declared  by the Board of  Directors  with
respect to the Common  Stock,  and 1.00* times the  aggregate  per share  amount
(payable in kind) of all non-cash dividends or other distributions (other than a
dividend  payable in shares of Common Stock or a subdivision of the  outstanding
shares of Common Stock, by  reclassification or otherwise) declared by the Board
of  Directors  with respect to the Common  Stock,  to the same extent as, on the
same basis as, and in the same form as (whether payable in cash or in kind), any
dividends with respect to shares of Common Stock.  With respect to each dividend
payable in respect of the Class C Junior  Preferred  Stock,  the record date for
such  dividend  shall  be the  same as the  record  date  for the  corresponding
dividend in respect of the Common Stock.  Such dividends shall be payable on the
dates  specified by the Board of Directors as the dates for payment of dividends
in  respect of shares of Common  Stock  (each of such  dates  being a  "dividend
payment date")(unless such day is not a business day, in which event on the next
succeeding  business day). Such dividends shall be paid to the holders of record
at the close of business on the date (the "record date")  specified by the Board
of Directors of the Corporation at the time such dividend is declared;  provided
that such date shall not be more than 60 days nor less than 10 days prior to the
respective dividend payment date. In the event the Corporation shall at any time
after the date of initial  issuance of the Class C Junior  Preferred  Stock (the
"Issuance Date"),  (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which each share of Class C Junior Preferred Stock was entitled to
receive immediately prior to such event under the first sentence of this Section
2(a) shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immedi-

ately after such event and the  denominator  of which is the number of shares of
Common Stock that were outstanding immediately prior to such event.

     (b) So  long as any  shares  of the  Class C  Junior  Preferred  Stock  are
outstanding,  no dividends shall be declared or paid or set apart for payment or
other distribution  declared or made upon Parity Securities or Junior Securities
by the Corporation, unless a dividend in the amount and form provided for herein
is  paid or set  apart  for  payment  on or in  respect  of the  Class C  Junior
Preferred Stock.

     3. Voting Rights.  The holders of shares of Class C Junior  Preferred Stock
shall have the following voting rights:

     (a)  Except  as  otherwise   provided   herein,   in  the   Certificate  of
Incorporation  or  under  applicable  law,  (i)  each  share  of  Class C Junior
Preferred  Stock  and each  share of Class D  Junior  Preferred  Stock  shall be
entitled to vote together  with the Common Stock on all matters  submitted for a
vote of holders of Common Stock as a single class, (ii) subject to the provision
for adjustment hereinafter set forth, shall be entitled to 1.00* votes per share
of Class C Junior  Preferred  Stock and (iii) shall be entitled to notice of any
stockholders'  meeting in accordance with the Certificate of  Incorporation  and
bylaws of the Corporation.  In the event the Corporation shall at any time after
the Issuance  Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the  number  of votes  per  share to which  holders  of shares of Class C Junior
Preferred Stock were entitled  immediately prior to such event shall be adjusted
by multiplying  such number by a fraction,  the numerator of which is the number
of shares of Common  Stock  outstanding  immediately  after  such  event and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

     (b)  So  long  as  any  shares  of  Class  C  Junior  Preferred  Stock  are
outstanding, the Corporation shall not,

                                       A-3

without the written  consent or  affirmative  vote at a meeting  called for that
purpose  of the  holders of  two-thirds  or more of the shares of Class C Junior
Preferred Stock then  outstanding,  amend,  alter or repeal,  whether by merger,
consolidation,  combination,  reclassification or otherwise,  the Certificate of
Incorporation  or  by-laws  of  the  Corporation  or of  any  provision  thereof
(including  the adoption of a new  provision  thereof)  which would result in an
alteration or  circumvention  of the voting powers,  designation and preferences
and  relative   participating,   optional   and  other   special   rights,   and
qualifications,  limitations and  restrictions  of the Class C Junior  Preferred
Stock.

     (c) The consent or votes  required in Section  3(b) shall be in addition to
any approval of stockholders of the Corporation  which may be required by law or
pursuant to any provision of the Certificate of Incorporation  or bylaws,  which
approval shall be obtained by vote of the stockholders of the Corporation in the
manner provided in Section 3(a).

     4.  Reacquired  Shares.  Any  shares  of  Class C  Junior  Preferred  Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled promptly after the acquisition  thereof. All such
shares shall upon their  cancellation  become  authorized but unissued shares of
Preferred  Stock and may be reissued as part of a new series of Preferred  Stock
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

     5.  Liquidation,  Dissolution  or  Winding  Up. (a) Upon any  voluntary  or
involuntary  liquidation,  dissolution  or  winding  up of the  Corporation,  no
distribution  shall be made to the holders of Junior  Securities  unless,  prior
thereto,  the  holders of shares of Class C Junior  Preferred  Stock  shall have
received $0.01 per share (the "Class C Liquidation Preference"), and the holders
of Parity  Securities  shall have received any  liquidation  preference due them
(the "Parity Preference"). Following the payment of the full amount of the Class
C  Liquidation  Preference,  no  additional  distributions  shall be made to the
holders of shares of Class C Junior Preferred Stock unless,  prior thereto,  the
holders of shares of Common  Stock shall have  received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i)

 
                                       A-4
<PAGE>


the Class C Liquidation  Preference by (ii) 1.00* (as appropriately  adjusted as
set forth in Section  5(c) below to reflect such events as stock  splits,  stock
dividends and  recapitalizations  with respect to the Common Stock) (such number
in clause  (ii)  being  hereinafter  referred  to as the  "Adjustment  Number").
Following the payment of the full amount of the Class C Liquidation  Preference,
the Parity  Preference and the Common  Adjustment in respect of all  outstanding
shares of Class C Junior  Preferred  Stock,  Class D Junior  Preferred Stock and
Common Stock, respectively, holders of shares of Class C Junior Preferred Stock,
Class D Junior  Preferred Stock and Common Stock shall receive their ratable and
proportionate  share of the remaining  assets to be  distributed in the ratio of
the Adjustment  Number to 1 with respect to such Class C Junior  Preferred Stock
and Class D Junior  Preferred  Stock,  and Common  Stock,  on a per share basis,
respectively.

     (b) In the event,  however,  that there are not sufficient assets available
to permit  payment in full of the Class C Liquidation  Preference and the Parity
Preference,  then such  remaining  assets  shall be  distributed  ratably to the
holders  of all  such  shares  in  proportion  to their  respective  liquidation
preferences.  In the  event,  however,  that  there  are not  sufficient  assets
available  to  permit  payment  in  full of the  Common  Adjustment,  then  such
remaining assets shall be distributed ratably to the holders of Common Stock.

     (c) In the event the Corporation  shall at any time after the Issuance Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding  Common Stock, or (iii) combine the outstanding Common
Stock  into a smaller  number of shares,  then in each such case the  Adjustment
Number  in  effect  immediately  prior  to  such  event  shall  be  adjusted  by
multiplying such Adjustment Number by a fraction,  the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

     6.  Consolidation,  Merger,  Share  Exchange,  etc. In case the Corporation
shall enter into any consolidation,

- --------
* See Section 5.20.

 
                                       A-5
<PAGE>


merger, share exchange,  combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or  securities,  cash
and/or  any other  property,  then in any such case the shares of Class C Junior
Preferred  Stock shall at the same time be similarly  exchanged or changed in an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 1.00* times the aggregate amount of stock, securities,  cash and/or any
other  property  (payable in kind),  as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time after the  Issuance  Date (i) declare  any  dividend on Common
Stock payable in shares of Common Stock,  (ii) subdivide the outstanding  Common
Stock,  or (iii) combine the  outstanding  Common Stock into a smaller number of
shares,  then in each such case the amount set forth in the  preceding  sentence
with  respect to the  exchange  or change of shares of Class C Junior  Preferred
Stock shall be adjusted by multiplying such amount by a fraction,  the numerator
of which is the number of shares of Common Stock  outstanding  immediately after
such event and the  denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

     7. Redemption.  (a) Except as set forth in Section 7(b) the shares of Class
C Junior Preferred Stock shall not be redeemable.

     (b) If the  Right of First  Refusal  is  Exercised,  each  share of Class C
Junior  Preferred Stock shall,  within 45 days of the receipt by the Corporation
of the Net Proceeds, be redeemed by the Corporation for a pro rata (by number of
shares of Class C Junior  Preferred  Stock  originally  issued) share of the Net
Proceeds. Such redemption shall be, at the election of the Corporation,  payable
either (i) in cash, subject to any requirements of law or the Corporation's debt
instruments,  or (ii) in shares of Common Stock of the Corporation valued at the
greater of $30 per share  [subject to  adjustment  if change in NTL Common Stock
prior  to  Issuance  Date]  or the NTL  Average  Market  Price as of the date of
receipt of the proceeds by the Corporation.

     (c)  "Net  Proceeds"   shall  mean  the  net  proceeds   received  for  the
Corporation's equity interest (as of the Issuance Date) in Cable London (without
regard to debt, loans from the Corporation to Cable London or the debt component
(i.e., face amount and accrued and unpaid interest) of any convertible security)
from the  consummation  of the sale of the  interest  under the  Rights of First
Refusal);  provided  that such amount  shall be adjusted as follows:  (i) if the
convertible  debt in Cable London has been  converted  prior to or in connection
with the  exercise  of the Right of First  Refusal,  the Net  Proceeds  shall be
decreased by an amount equal to the debt component of the Corporation's share of
such  convertible  debt,  (ii) if such  convertible  debt has not been converted
prior to or in connection  with the exercise of the Right of First Refusal,  the
Net  Proceeds  shall  be  increased  by an  amount  equal  to the  value  of the
Corporation's  share of such  convertible  debt (less the debt component of such
convertible  debt) and (iii) such amount will be reduced by taxes which would be
payable on such sale at the Tax Rate,  without  giving  effect to any credits or
other  adjustments  available to the Corporation or its subsidiaries as a result
of factors not related to the Corporation's interest in Cable London.

     (d) Nothing  contained  herein  shall be deemed to restrict or prohibit the
Corporation  from  acquiring  shares of Class C Preferred  Stock  otherwise then
pursuant to redemption pursuant to Section 7(b) hereof.

     8. Exchange.  If (i) the Corporation  shall so elect in its sole discretion
or (ii) the Right of First Refusal is Resolved, the Corporation shall, within 45
days of the date of election  with  respect to clause (i) or the date the Rights
of Refusal is Resolved with respect to clause (ii), exchange each share of Class
C Junior  Preferred  Stock into 1.00*  shares (or, if there has been one or more
adjustments  pursuant to the last sentence of Section 2(a), the adjusted  number
of shares) of Common Stock of the Corporation.

     9. Procedure for Redemption or Exchange.  (a) In the event of redemption of
the Class C Junior  Preferred  Stock pursuant to Section 7 or an exchange of the
shares of Class C Junior  Preferred  Stock pursuant to Section 8,

- --------
* See Section 5.20.

 
                                       A-7
<PAGE>


notice of such redemption or exchange shall be given to each holder of record of
the shares to be  redeemed or  exchanged  at such  holder's  address as the same
appears on the stock transfer books of the  Corporation at least 30 but not more
than 45 days before the date fixed for  redemption or exchange,  as the case may
be,  provided,  however,  that no  failure  to give such  notice  nor any defect
therein shall affect the validity of the  redemption or exchange of any share of
Class C Junior  Preferred  Stock to be  redeemed or  exchanged  except as to the
holder to whom the  Corporation  has failed to give said  notice or except as to
the holder whose  notice was  defective.  Each such notice shall state:  (i) the
redemption   date  or  exchange  date;   (ii)  the  amount  and  nature  of  the
consideration  to be paid in  respect of each  share;  (iii) the place or places
where  certificates  for such shares are to be  surrendered  for  redemption  or
exchange;  (iv) the specific  provision hereof pursuant to which such redemption
or exchange is to be made;  and (v) that  dividends on the shares to be redeemed
or exchanged will cease to accrue on such redemption date or exchange date. Upon
giving any notice of a  redemption  pursuant  to Section 7 or notice of exchange
pursuant  to Section 8, the  Corporation  shall  become  obligated  to redeem or
exchange the shares of Class C Junior  Preferred  Stock specified in such notice
on the redemption  date or exchange date, as the case may be,  specified in such
notice.

     (b) Notice  having been given as aforesaid,  from and after the  redemption
date or the exchange date (unless, in the case of a redemption, default shall be
made by the  Corporation  in providing  money for the payment of the  redemption
price of the shares called for  redemption  or, in the case of an exchange,  the
Corporation  defaults in issuing  Common  Stock or fails to pay or set aside for
payment  accrued and unpaid  dividends on the Class C Junior  Preferred Stock to
the exchange  date),  dividends on the shares of Class C Junior  Preferred Stock
called for redemption or exchange  shall cease to accrue,  and all rights of the
holders thereof as stockholders of the Corporation  (except the right to receive
from the Corporation the redemption  price without  interest or the Common Stock
and accrued and unpaid  dividends on the Class C Junior  Preferred  Stock to the
exchange date) shall cease. Upon surrender in accordance with said notice of the
certificates  for any shares so  redeemed  or  exchanged  (properly  endorsed or
assigned for  transfer,  if the Board of Directors of the  Corporation  shall so
require and the notice

 
                                       A-8
<PAGE>

shall so state), such share shall be redeemed or exchanged by the Corporation at
the redemption price or rate of exchange aforesaid.

     (c) The  Corporation  will pay any and all issuance and delivery taxes that
may be payable  in  respect  of the  issuance  or  delivery  of Common  Stock in
exchange for shares of Class C Junior  Preferred  Stock.  The Corporation  shall
not, however,  be required to pay any tax which may be payable in respect of any
transfer  involved in the  issuance and delivery of Common Stock in a name other
than that in which the shares of Class C Junior Preferred Stock so exchange were
registered,  and no such issuance or delivery shall be made unless and until the
person  requesting  such issuance has paid to the  Corporation the amount of any
such tax or has established to the satisfaction of the Corporation that such tax
has been paid.

     (d) If a notice of redemption shall have been given, such redemption is for
consideration  consisting  solely of cash and if, prior to the redemption  date,
the Corporation shall have irrevocably  deposited the aggregate redemption price
of the shares of Class C Junior  Preferred Stock to be redeemed in trust for the
pro rata benefit of the holders of the shares of Class C Junior  Preferred Stock
to be  redeemed,  so as to be and to continue to be available  therefor,  with a
bank or trust company that (i) is organized  under the laws of the United States
of America or any state  thereof,  (ii) has capital and surplus of not less than
$250,000,000  and (iii) has,  or, if it has no publicly  traded debt  securities
rated by a nationally  recognized  rating  agency,  is the  subsidiary of a bank
holding company that has,  publicly traded debt securities rated at least "A" or
the  equivalent  thereof  by  Standard  &  Poor's  Corporation  or  "A-2" or the
equivalent by Moody's Investor Service Inc., then upon making such deposit,  all
rights of holders of the shares so called for redemption shall cease, except the
right of holders of such shares to receive the redemption price against delivery
of such  shares,  but  without  interest,  and  such  shares  shall  cease to be
outstanding.  Any funds so deposited  that are unclaimed by holders of shares at
the end of  three  years  from  such  redemption  date  shall be  repaid  to the
Corporation  upon its request,  after which  repayment  the holders of shares of
Class C Junior  Preferred  Stock so called for  redemption  shall  thereafter be
entitled to look only to the Corporation for payment of the redemption price.

 
                                       A-9

     (e) In the event of redemption of shares of Class C Junior  Preferred Stock
for  shares of Common  Stock  pursuant  to Section 7 or an  exchange  of Class C
Junior Preferred Stock for shares of Common Stock pursuant to Section 8:

          (i) such  redemption or exchange shall be deemed to have been effected
     on the  redemption  date or the exchange  date, as the case may be, and the
     person in whose name or names any certificate or certificates for shares of
     Common Stock shall be issuable upon such  redemption  or exchange  shall be
     deemed to have  become the  holder of record of the shares of Common  Stock
     represented  thereby as of the close of business on the redemption  date or
     the exchange date, as the case may be;

          (ii) all such  shares  of  Common  Stock  issued  upon  redemption  or
     exchange of the Class C Junior  Preferred  Stock will upon issuance be duly
     and validly issued and fully paid and non-assessable, free of all liens and
     charges and not subject to any preemptive rights;

          (iii)  effective as of the close of business on the redemption date or
     exchange date, as the case may be, the holder thereof shall be deemed to be
     the holder of the shares of Common  Stock for which such  shares of Class C
     Junior Preferred Stock were redeemed or exchanged, as the case may be, and,
     as from the redemption  date or the exchange date, as the case may be, such
     holder shall be entitled to all rights of a Common Stock holder;

          (iv) prior to the  issuance  of any such shares of Common  Stock,  the
     Corporation  shall  comply with all  applicable  federal and state laws and
     regulations which require action to be taken by the Corporation; and

          (v) no fractional shares of Common Stock shall be issued,  but in lieu
     thereof  the  Corporation  shall pay a cash  adjustment  in respect of such
     fractional  interest  in  an  amount  equal  to  such  fractional  interest
     multiplied  by the  closing  price  reported  by the  principal  securities
     exchange on which the shares

 
                                      A-10
<PAGE>


     of Common  Stock are listed and traded on the  redemption  date or exchange
     date, as the case may be.
 
     (f) The  Corporation  covenants  that it will at all times reserve and keep
available,  free from  preemptive  rights,  such  number of its  authorized  but
unissued  shares of Common  Stock  and/or  its  shares of Common  Stock  held as
treasury  stock as shall be required for the purpose of effecting the redemption
or exchange of the Class C Junior Preferred Stock.

     10. Fiduciary Duty. The Board of Directors of the Corporation  shall,  with
respect to all  matters  except  those set forth in  Sections 5, 7, 8, 9 and 13,
have the obligations and duties  (including  fiduciary duties) to the holders of
the  Class C  Junior  Preferred  Stock to the same  extent  and as if they  were
holders of the Common Stock. With respect to the matters set forth in Section 5,
7, 8, 9 and 13,  the Board of  Directors  of the  Corporation  shall act in good
faith and, in the event that the  Corporation is not reasonably  likely to enter
into any agreement, arrangement or understanding directly or indirectly relating
to the Right of First  Refusal or the  ownership  interest in Cable London which
would result in an exchange  pursuant to clause (ii) of Section 8, and the Right
of First Refusal is reasonably likely to be exercised, the Corporation shall use
its reasonable efforts to maximize the proceeds to be received from the exercise
thereof.

     11.  Ranking.  The Class C Junior  Preferred  Stock shall,  with respect to
dividend  rights,  rank on a parity with,  the common stock,  par value $.01 per
share,  of  the  Corporation  (the  "Common  Stock")  and  the  Class  D  Junior
Participating Preferred Stock, par value $.01 per share, of the Corporation (the
"Class D Junior  Preferred  Stock").  With  respect  to rights  on  liquidation,
dissolution and winding up, the Class C Junior  Preferred Stock shall rank prior
to all  classes  of the  Common  Stock,  on a  parity  with  the  Class D Junior
Preferred  Stock and junior to all other series of Preferred  Stock.  All equity
securities of the Corporation to which the Class C Junior  Preferred Stock ranks
prior  (whether  with  respect to dividends  or upon  liquidation,  dissolution,
winding up or  otherwise),  are  collectively  referred to herein as the "Junior
Securities."  All equity  securities of the  Corporation  with which the Class C
Junior  Preferred  Stock ranks on a parity (whether with respect to dividends or
upon liquidation, dissolution

 
                                      A-11
<PAGE>

or winding up),  including the Class D Junior  Preferred Stock, are collectively
referred  to herein as the "Parity  Securities."  All equity  securities  of the
Corporation to which the Class C Junior  Preferred  Stock ranks junior  (whether
with respect to dividends or upon  liquidation,  dissolution  or winding up) are
collectively   referred  to  herein  as  "Senior  Securities".   The  respective
definitions of Junior Securities,  Parity Securities and Senior Securities shall
also include any options  exercisable for or convertible  into any of the Junior
Securities, Parity Securities and Senior Securities, as the case may be.

     12.  Reports.  So long as any of the  Class C  Junior  Preferred  Stock  is
outstanding, the Corporation will furnish the holders thereof with the quarterly
and annual  financial  reports that the Corporation is required to file with the
Securities  and Exchange  Commission  pursuant to Section 13 or Section 15(d) of
the  Securities  Exchange  Act of 1934 or, in the event the  Corporation  is not
required to file such reports,  reports containing the same information as would
be required in such reports.

     13. Definitions. "Exercised" shall mean that the Right of First Refusal has
been  validly  exercised by Telewest  (other than  pursuant to Clause (B) of the
definition of "Resolved") and the Corporation (or the relevant subsidiary of the
Corporation)  has  received  the proceeds  therefrom  in  consideration  for the
delivery of the equity interests thereunder.

     "NTL Average Market Price" means the average of the average of the high and
low sales prices of the Common Stock of the Corporation on the principal  market
on which it is  traded  for each of the five  trading  days  ending  on the last
trading day prior to the date of determination.

     "Resolved"  shall mean that (A) the Right of First  Refusal is no longer of
any legal force and effect or (B) that the  Corporation  shall have entered into
an agreement,  arrangement or understanding with Telewest directly or indirectly
relating to a business  combination  between the Corporation and Telewest or the
Right of First Refusal or the ownership interests in Cable London.

     "Right of First  Refusal"  shall mean the right of preemption  set forth in
Article 15(c) of the Articles of Association of Cable London.

Section 103 thereof, HEREBY CERTIFIES:

     That pursuant to the authority conferred upon the Board of Directors by the
Certificate  of  Incorporation  of the  said  Corporation,  the  said  Board  of
Directors on ______, 1998 adopted the following  resolution creating a series of
________________  shares  of  Preferred  Stock  designated  as  Class  D  Junior

     RESOLVED,  that pursuant to the authority  vested in the Board of Directors
of this  Corporation  in accordance  with the  provisions of its  Certificate of
Incorporation,  a series of Preferred  Stock of the Corporation be and it hereby
is created,  and that the  designation and amount thereof and the voting powers,

receive,  when,  as and if  declared  by the  Board of  Directors,  out of funds
legally  available  for the  payment of  dividends,  contemporaneously  with any
dividends  with  respect to shares of Common  Stock (as defined in Section  11),
dividends in an amount per share (rounded to the nearest cent) equal to, subject
to the provision for adjustment hereinafter set forth, 1.00* times the aggregate
per share  amount of cash  dividends  declared  by the Board of  Directors  with
respect to the Common  Stock,  and 1.00* times the  aggregate  per share  amount
(payable in kind) of all non-cash dividends or other distributions (other than a
dividend  payable in shares of Common Stock or a subdivision of the  outstanding
shares of Common Stock, by  reclassification or otherwise) declared by the Board
of  Directors  with respect to the Common  Stock,  to the same extent as, on the
same basis as, and in the same form as (whether payable in cash or in kind), any
dividends with respect to shares of Common Stock.  With respect to each dividend
payable in respect of the Class D Junior  Preferred  Stock,  the record date for
such  dividend  shall  be the  same as the  record  date  for the  corresponding
dividend in respect of the Common Stock.  Such dividends shall be payable on the
dates  specified by the Board of Directors as the dates for payment of dividends
in  respect of shares of Common  Stock  (each of such  dates  being a  "dividend
payment date")(unless such day is not a business day, in which event on the next
succeeding  business day). Such dividends shall be paid to the holders of record
at the close of business on the date (the "record date")  specified by the Board
of Directors of the Corporation at the time such dividend is declared;  provided
that such date shall not be more than 60 days nor less than 10 days prior to the
respective dividend payment date. In the event the Corporation shall at any time
after the date of initial  issuance of the Class D Junior  Preferred  Stock (the
"Issuance Date"),  (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which each share of Class D Junior Preferred Stock was entitled to
receive immediately prior to such event under the first sentence of this Section
2(a) shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immedi-

                                       A-2

ately after such event and the  denominator  of which is the number of shares of
Common Stock that were outstanding immediately prior to such event.

     (b) So  long as any  shares  of the  Class D  Junior  Preferred  Stock  are
outstanding,  no dividends shall be declared or paid or set apart for payment or
other distribution  declared or made upon Parity Securities or Junior Securities
by the Corporation, unless a dividend in the amount and form provided for herein
is  paid or set  apart  for  payment  on or in  respect  of the  Class D  Junior
Preferred Stock.

     3. Voting Rights.  The holders of shares of Class D Junior  Preferred Stock
shall have the following voting rights:

     (a)  Except  as  otherwise   provided   herein,   in  the   Certificate  of
Incorporation  or  under  applicable  law,  (i)  each  share  of  Class D Junior
Preferred  Stock  and each  share of Class C  Junior  Preferred  Stock  shall be
entitled to vote together  with the Common Stock on all matters  submitted for a
vote of holders of Common Stock as a single class, (ii) subject to the provision
for adjustment hereinafter set forth, shall be entitled to 1.00* votes per share
of Class D Junior  Preferred  Stock and (iii) shall be entitled to notice of any
stockholders'  meeting in accordance with the Certificate of  Incorporation  and
bylaws of the Corporation.  In the event the Corporation shall at any time after
the Issuance  Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the  number  of votes  per  share to which  holders  of shares of Class D Junior
Preferred Stock were entitled  immediately prior to such event shall be adjusted
by multiplying  such number by a fraction,  the numerator of which is the number
of shares of Common  Stock  outstanding  immediately  after  such  event and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

     (b)  So  long  as  any  shares  of  Class  D  Junior  Preferred  Stock  are
outstanding, the Corporation shall not, 

- --------
* See Section 5.20.

 
                                       A-3
<PAGE>


without the written  consent or  affirmative  vote at a meeting  called for that
purpose  of the  holders of  two-thirds  or more of the shares of Class D Junior
Preferred Stock then  outstanding,  amend,  alter or repeal,  whether by merger,
consolidation,  combination,  reclassification or otherwise,  the Certificate of
Incorporation  or  by-laws  of  the  Corporation  or of  any  provision  thereof
(including  the adoption of a new  provision  thereof)  which would result in an
alteration or  circumvention  of the voting powers,  designation and preferences
and  relative   participating,   optional   and  other   special   rights,   and
qualifications,  limitations and  restrictions  of the Class D Junior  Preferred
Stock.

     (c) The consent or votes  required in Section  3(b) shall be in addition to
any approval of stockholders of the Corporation  which may be required by law or
pursuant to any provision of the Certificate of Incorporation  or bylaws,  which
approval shall be obtained by vote of the stockholders of the Corporation in the
manner provided in Section 3(a).

     4.  Reacquired  Shares.  Any  shares  of  Class D  Junior  Preferred  Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled promptly after the acquisition  thereof. All such
shares shall upon their  cancellation  become  authorized but unissued shares of
Preferred  Stock and may be reissued as part of a new series of Preferred  Stock
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

     5.  Liquidation,  Dissolution  or  Winding  Up. (a) Upon any  voluntary  or
involuntary  liquidation,  dissolution  or  winding  up of the  Corporation,  no
distribution  shall be made to the holders of Junior  Securities  unless,  prior
thereto,  the  holders of shares of Class D Junior  Preferred  Stock  shall have
received $0.01 per share (the "Class D Liquidation Preference"), and the holders
of Parity  Securities  shall have received any  liquidation  preference due them
(the "Parity Preference"). Following the payment of the full amount of the Class
D  Liquidation  Preference,  no  additional  distributions  shall be made to the
holders of shares of Class D Junior Preferred Stock unless,  prior thereto,  the
holders of shares of Common  Stock shall have  received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i)

 
                                       A-4
<PAGE>


the Class D Liquidation  Preference by (ii) 1.00* (as appropriately  adjusted as
set forth in Section  5(c) below to reflect such events as stock  splits,  stock
dividends and  recapitalizations  with respect to the Common Stock) (such number
in clause  (ii)  being  hereinafter  referred  to as the  "Adjustment  Number").
Following the payment of the full amount of the Class D Liquidation  Preference,
the Parity  Preference and the Common  Adjustment in respect of all  outstanding
shares of Class C Junior  Preferred  Stock,  Class D Junior  Preferred Stock and
Common Stock, respectively, holders of shares of Class C Junior Preferred Stock,
Class D Junior  Preferred Stock and Common Stock shall receive their ratable and
proportionate  share of the remaining  assets to be  distributed in the ratio of
the Adjustment  Number to 1 with respect to such Class C Junior  Preferred Stock
and Class D Junior  Preferred  Stock,  and Common  Stock,  on a per share basis,
respectively.

     (b) In the event,  however,  that there are not sufficient assets available
to permit  payment in full of the Class D Liquidation  Preference and the Parity
Preference,  then such  remaining  assets  shall be  distributed  ratably to the
holders  of all  such  shares  in  proportion  to their  respective  liquidation
preferences.  In the  event,  however,  that  there  are not  sufficient  assets
available  to  permit  payment  in  full of the  Common  Adjustment,  then  such
remaining assets shall be distributed ratably to the holders of Common Stock.

     (c) In the event the Corporation  shall at any time after the Issuance Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding  Common Stock, or (iii) combine the outstanding Common
Stock  into a smaller  number of shares,  then in each such case the  Adjustment
Number  in  effect  immediately  prior  to  such  event  shall  be  adjusted  by
multiplying such Adjustment Number by a fraction,  the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

     6.  Consolidation,  Merger,  Share  Exchange,  etc. In case the Corporation
shall enter into any consolidation, 

- --------
* See Section 5.20.

 
                                       A-5
<PAGE>


merger, share exchange,  combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or  securities,  cash
and/or  any other  property,  then in any such case the shares of Class D Junior
Preferred  Stock shall at the same time be similarly  exchanged or changed in an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 1.00* times the aggregate amount of stock, securities,  cash and/or any
other  property  (payable in kind),  as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time after the  Issuance  Date (i) declare  any  dividend on Common
Stock payable in shares of Common Stock,  (ii) subdivide the outstanding  Common
Stock,  or (iii) combine the  outstanding  Common Stock into a smaller number of
shares,  then in each such case the amount set forth in the  preceding  sentence
with  respect to the  exchange  or change of shares of Class D Junior  Preferred
Stock shall be adjusted by multiplying such amount by a fraction,  the numerator
of which is the number of shares of Common Stock  outstanding  immediately after
such event and the  denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

     7. Redemption.  (a) Except as set forth in Section 7(b) the shares of Class
D Junior Preferred Stock shall not be redeemable.

     (b) If the  Right of First  Refusal  is  Exercised,  each  share of Class D
Junior  Preferred Stock shall,  within 45 days of the receipt by the Corporation
of the Net Proceeds, be redeemed by the Corporation for a pro rata (by number of
shares of Class D Junior  Preferred  Stock  originally  issued) share of the Net
Proceeds. Such redemption shall be, at the election of the Corporation,  payable
either (i) in cash, subject to any requirements of law or the Corporation's debt
instruments,  or (ii) in shares of Common Stock of the Corporation valued at the
greater of $30 per share  [subject to  adjustment  if change in NTL Common Stock
prior  to  Issuance  Date]  or the NTL  Average  Market  Price as of the date of
receipt of the proceeds by the Corporation.

     (c) "Net  Proceeds"  shall mean the net  proceeds  received  for the equity
interest (as of the Issuance Date) in Birmingham  Cable (without regard to debt,
loans from the Corporation to Birmington Cable or the debt component (i.e., face
amount and accrued and unpaid  interest) of any  convertible  security) from the
consummation  of the sale of the interest under the Rights of First Refusal less
taxes which would be payable on such sale at the Tax Rate without  giving effect
to  any  credits  or  other  adjustments  available  to the  Corporation  or its
subsidiaries as a result of factors not related to the Corporation's interest in
Birmingham Cable.

     (d) Nothing  contained  herein  shall be deemed to restrict or prohibit the
Corporation  from  acquiring  shares of Class D Preferred  Stock  otherwise then
pursuant to redemption pursuant to Section 7(b) hereof.

     8. Exchange.  If (i) the Corporation  shall so elect in its sole discretion
or (ii) the Right of First Refusal is Resolved, the Corporation shall, within 45
days of the date of election  with  respect to clause (i) or the date the Rights
of Refusal is Resolved with respect to clause (ii), exchange each share of Class
D Junior  Preferred  Stock into 1.00*  share (or,  if there has been one or more
adjustments  pursuant to the last sentence of Section 2(a), the adjusted  number
of shares) of Common Stock of the Corporation.

     9. Procedure for Redemption or Exchange.  (a) In the event of redemption of
the Class D Junior  Preferred  Stock pursuant to Section 7 or an exchange of the
shares of Class D Junior  Preferred  Stock pursuant to Section 8, notice of such
redemption or exchange  shall be given to each holder of record of the shares to
be redeemed or  exchanged  at such  holder's  address as the same appears on the
stock  transfer  books of the  Corporation at least 30 but not more than 45 days
before the date fixed for redemption or exchange,  as the case may be, provided,
however, that no failure to give such notice nor any defect therein shall affect
the  validity  of the  redemption  or  exchange  of any  share of Class D Junior
Preferred Stock to be redeemed or exchanged  except as to the holder to whom the
Corporation has failed to give said notice or except as to the holder

*  See Section 5.20.

 
                                       A-7
<PAGE>


whose notice was  defective.  Each such notice shall state:  (i) the  redemption
date or exchange  date;  (ii) the amount and nature of the  consideration  to be
made in respect of each share;  (iii) the place or places where certificates for
such shares are to be surrendered for redemption or exchange;  (iv) the specific
provision  hereof  pursuant to which such  redemption or exchange is to be made;
and (v) that  dividends on the shares to be redeemed or exchanged  will cease to
accrue on such  redemption  date or exchange  date.  Upon giving any notice of a
redemption  pursuant to Section 7 or notice of  exchange  pursuant to Section 8,
the Corporation shall become obligated to redeem or exchange the shares of Class
D Junior  Preferred  Stock  specified in such notice on the  redemption  date or
exchange date, as the case may be, specified in such notice.

     (b) Notice  having been given as aforesaid,  from and after the  redemption
date or the exchange date (unless, in the case of a redemption, default shall be
made by the  Corporation  in providing  money for the payment of the  redemption
price of the shares called for  redemption  or, in the case of an exchange,  the
Corporation  defaults in issuing  Common  Stock or fails to pay or set aside for
payment  accrued and unpaid  dividends on the Class D Junior  Preferred Stock to
the exchange  date),  dividends on the shares of Class D Junior  Preferred Stock
called for redemption or exchange  shall cease to accrue,  and all rights of the
holders thereof as stockholders of the Corporation  (except the right to receive
from the Corporation the redemption  price without  interest or the Common Stock
and accrued and unpaid  dividends on the Class D Junior  Preferred  Stock to the
exchange date) shall cease. Upon surrender in accordance with said notice of the
certificates  for any shares so  redeemed  or  exchanged  (properly  endorsed or
assigned for  transfer,  if the Board of Directors of the  Corporation  shall so
require  and the  notice  shall so  state),  such  share  shall be  redeemed  or
exchanged  by the  Corporation  at the  redemption  price  or rate  of  exchange
aforesaid.

     (c) The  Corporation  will pay any and all issuance and delivery taxes that
may be payable  in  respect  of the  issuance  or  delivery  of Common  Stock in
exchange for shares of Class D Junior  Preferred  Stock.  The Corporation  shall
not, however,  be required to pay any tax which may be payable in respect of any
transfer  involved in the  issuance and delivery of Common Stock in a name other
than that in

 
                                       A-8
<PAGE>


which the shares of Class D Junior  Preferred Stock so exchange were registered,
and no such  issuance  or  delivery  shall be made  unless  and until the person
requesting  such issuance has paid to the Corporation the amount of any such tax
or has established to the satisfaction of the Corporation that such tax has been
paid.

     (d) If a notice of redemption shall have been given, such redemption is for
consideration  solely  of  cash  and  if,  prior  to the  redemption  date,  the
Corporation shall have irrevocably  deposited the aggregate  redemption price of
the shares of Class D Junior Preferred Stock to be redeemed in trust for the pro
rata benefit of the holders of the shares of Class D Junior  Preferred  Stock to
be redeemed,  so as to be and to continue to be available therefor,  with a bank
or trust  company that (i) is organized  under the laws of the United  States of
America or any state  thereof,  (ii) has  capital  and  surplus of not less than
$250,000,000  and (iii) has,  or, if it has no publicly  traded debt  securities
rated by a nationally  recognized  rating  agency,  is the  subsidiary of a bank
holding company that has,  publicly traded debt securities rated at least "A" or
the  equivalent  thereof  by  Standard  &  Poor's  Corporation  or  "A-2" or the
equivalent by Moody's Investor Service Inc., then upon making such deposit,  all
rights of holders of the shares so called for redemption shall cease, except the
right of holders of such shares to receive the redemption price against delivery
of such  shares,  but  without  interest,  and  such  shares  shall  cease to be
outstanding.  Any funds so deposited  that are unclaimed by holders of shares at
the end of  three  years  from  such  redemption  date  shall be  repaid  to the
Corporation  upon its request,  after which  repayment  the holders of shares of
Class D Junior  Preferred  Stock so called for  redemption  shall  thereafter be
entitled to look only to the Corporation for payment of the redemption price.

     (e) In the event of redemption of shares of Class D Junior  Preferred Stock
for  shares of Common  Stock  pursuant  to Section 7 or an  exchange  of Class D
Junior Preferred Stock for shares of Common Stock pursuant to Section 8:

          (i) such  redemption or exchange shall be deemed to have been effected
     on the  redemption  date or the exchange  date, as the case may be, and the
     person in whose name or names any certificate or certificates for shares of
     Common Stock shall be issuable upon such

 
                                       A-9
<PAGE>


     redemption or exchange  shall be deemed to have become the holder of record
     of the  shares  of  Common  Stock  represented  thereby  as of the close of
     business on the redemption date or the exchange date, as the case may be;

          (ii) all such  shares  of  Common  Stock  issued  upon  redemption  or
     exchange of the Class D Junior  Preferred  Stock will upon issuance be duly
     and validly issued and fully paid and non-assessable, free of all liens and
     charges and not subject to any preemptive rights;

          (iii)  effective as of the close of business on the redemption date or
     exchange date, as the case may be, the holder thereof shall be deemed to be
     the holder of the shares of Common  Stock for which such  shares of Class D
     Junior Preferred Stock were redeemed or exchanged, as the case may be, and,
     as from the redemption  date or the exchange date, as the case may be, such
     holder shall be entitled to all rights of a Common Stock holder;

          (iv) prior to the  issuance  of any such shares of Common  Stock,  the
     Corporation  shall  comply with all  applicable  federal and state laws and
     regulations which require action to be taken by the Corporation;

          (v) no fractional shares of Common Stock shall be issued,  but in lieu
     thereof  the  Corporation  shall pay a cash  adjustment  in respect of such
     fractional  interest  in  an  amount  equal  to  such  fractional  interest
     multiplied  by the  closing  price  reported  by the  principal  securities
     exchange  on which the shares of Common  Stock are listed and traded on the
     redemption date or exchange date, as the case may be; and
 
     (f) The  Corporation  covenants  that it will at all times reserve and keep
available,  free from  preemptive  rights,  such  number of its  authorized  but
unissued  shares of Common  Stock  and/or  its  shares of Common  Stock  held as
treasury  stock as shall be required for the purpose of effecting the redemption
or exchange of the Class D Junior Preferred Stock.

     10. Fiduciary Duty. The Board of Directors of the Corporation  shall,  with
respect to all matters except

 
                                      A-10

<PAGE>


those set forth in Sections 5, 7, 8, 9 and 13, have the  obligations  and duties
(including  fiduciary  duties) to the  holders  of the Class D Junior  Preferred
Stock to the same extent and as if they were holders of the Common  Stock.  With
respect  to the  matters  set forth in  Section  5, 7, 8, 9 and 13, the Board of
Directors of the Corporation  shall act in good faith and, in the event that the
Corporation is not reasonably likely to enter into any agreement, arrangement or
understanding  directly or indirectly  relating to the Right of First Refusal or
the  ownership  interest in  Birmingham  Cable which would result in an exchange
pursuant  to  clause  (ii) of  Section  8, and the  Right of  First  Refusal  is
reasonably  likely to be exercised,  the  Corporation  shall use its  reasonable
efforts to maximize the proceeds to be received from the exercise thereof.

     11.  Ranking.  The Class D Junior  Preferred  Stock shall,  with respect to
dividend  rights,  rank on a parity with,  the common stock,  par value $.01 per
share,  of  the  Corporation  (the  "Common  Stock")  and  the  Class  C  Junior
Participating Preferred Stock, par value $.01 per share, of the Corporation (the
"Class C Junior  Preferred  Stock").  With  respect  to rights  on  liquidation,
dissolution and winding up, the Class D Junior  Preferred Stock shall rank prior
to all  classes  of the  Common  Stock,  on a  parity  with  the  Class C Junior
Preferred  Stock and junior to all other series of Preferred  Stock.  All equity
securities of the Corporation to which the Class D Junior  Preferred Stock ranks
prior  (whether  with  respect to dividends  or upon  liquidation,  dissolution,
winding up or  otherwise),  are  collectively  referred to herein as the "Junior
Securities."  All equity  securities of the  Corporation  with which the Class D
Junior  Preferred  Stock ranks on a parity (whether with respect to dividends or
upon  liquidation,  dissolution  or winding  up),  including  the Class C Junior
Preferred Stock, are collectively referred to herein as the "Parity Securities."
All equity  securities of the Corporation to which the Class D Junior  Preferred
Stock ranks junior  (whether  with  respect to  dividends  or upon  liquidation,
dissolution  or  winding  up) are  collectively  referred  to herein as  "Senior
Securities". The respective definitions of Junior Securities,  Parity Securities
and  Senior  Securities  shall  also  include  any  options  exercisable  for or
convertible  into any of the Junior  Securities,  Parity  Securities  and Senior
Securities, as the case may be.


 
                                      A-11
<PAGE>


     12.  Reports.  So long as any of the  Class D  Junior  Preferred  Stock  is
outstanding, the Corporation will furnish the holders thereof with the quarterly
and annual  financial  reports that the Corporation is required to file with the
Securities  and Exchange  Commission  pursuant to Section 13 or Section 15(d) of
the  Securities  Exchange  Act of 1934 or, in the event the  Corporation  is not
required to file such reports,  reports containing the same information as would
be required in such reports.

     13. Definitions. "Exercised" shall mean that the Right of First Refusal has
been validly  exercised by Telewest and/or General Cable (other than pursuant to
clause (B) of the definition of "Resolved") and the Corporation (or the relevant
subsidiary  of  the  Corporation)   has  received  the  proceeds   therefrom  in
consideration for the delivery of the equity interests thereunder.

     "NTL Average Market Price" means the average of the average of the high and
low sales prices of the Common Stock of the Corporation on the principal  market
on which it is  traded  for each of the five  trading  days  ending  on the last
trading day prior to the date of determination.

     "Resolved"  shall mean that (A) the Right of First  Refusal is no longer of
any legal force and effect or (B) that the  Corporation  shall have entered into
an agreement,  arrangement or  understanding  with Telewest and/or General Cable
directly  or  indirectly   relating  to  a  business   combination  between  the
Corporation and Telewest or the Right of First Refusal or the ownership interest
in Birmingham Cable.

     "Right of First Refusal" shall mean the right of first refusal set forth in
Section 5.2 of the Co-Ownership Agreement, dated March 12, 1990, between US West
International  Holdings Inc. and Comcast  Cablevision  of  Birmingham,  Inc., as
subsequently amended, supplemented and novated.

                      [UNDERTAKING OF COMCAST CORPORATION]


     The undersigned,  COMCAST CORPORATION ("Comcast"), hereby acknowledges that
NTL  Incorporated  ("NTL")  will be  entering  into  the  Agreement  and Plan of
Amalgamation (the "Agreement") among NTL, NTL (Bermuda) Limited,  and Comcast UK
Cable Partners Limited ("Partners") and otherwise acting in specific reliance on
this agreement.

     Comcast  irrevocably agrees that it will, and will procure that each of its
subsidiaries will, during the period commencing on the date hereof and ending on
the  earlier  of the  Effective  Time  (as  defined  in the  Agreement)  and the
termination of this agreement:

     (i) comply with the provisions of Section 4.2(a) of the Agreement;

     (ii) not sell, transfer,  dispose or assign, directly or indirectly, all or
any part of its interest in Partners other than pursuant to the Agreement;

     (iii) vote in favor of the Agreement at the Partners  Shareholder  Meetings
(as defined in the Agreement);

     (iv) not enter into any new agreement or other arrangement  between Comcast
and its  subsidiaries  (other than  Partners and its  subsidiaries),  on the one
hand,  and Partners or any subsidiary of Partners or any  Significant  Affiliate
(as defined in the  Agreement),  on the other hand,  or amend any such  existing
agreement or other arrangement; and

     (v) if any interest in any Significant Affiliate is transferred by Partners
or any subsidiary of Partners to Comcast or any  subsidiary of Comcast,  Comcast
shall make  arrangements  to  effectively  transfer  such interest to NTL at the
Effective Time without any additional consideration (other than the Amalgamation
Consideration) being payable by NTL.

<PAGE>
 

     Comcast further agrees,  on behalf of Comcast and its  subsidiaries  (other
than Partners and its subsidiaries),  that from and after the Effective Time (as
defined in the Agreement) it will:

     (i) for so long as Comcast shall be subject to the filing  requirements  of
Section 13 of the  Securities  Exchange  Act of 1934 with respect to NTL Capital
Stock (as defined in the Agreement), vote any shares of NTL Capital Stock in the
same  proportion  as voted by  stockholders  of NTL  generally  (other  than any
affiliate  thereof),  provided that this  covenant  shall not apply to any class
vote of the NTL Class C  Preferred  or NTL Class D Preferred  (in each case,  as
defined in the Agreement);

     (ii) use its reasonable efforts to provide that any person now serving as a

FOR IMMEDIATE RELEASE



                     NTL INCORPORATED ANNOUNCES AMALGAMATION
                AGREEMENT WITH COMCAST UK CABLE PARTNERS LIMITED

                  COMCAST UK SHAREHOLDERS TO RECEIVE NTL SHARES


     New York, New York  (February 5, 1998) - NTL  Incorporated  (NASDAQ:  NTLI;
EASDAQ:  NTLI.ED) announced today that it had entered into an agreement and plan
of  amalgamation  (the  "Agreement")  with  Comcast  UK Cable  Partners  Limited
("Comcast UK").

     Under the Agreement,  Comcast UK shareholders will receive 0.3745 shares of
NTL Common Stock for each share of Comcast UK Common Stock. Based on yesterday's
closing price of NTL Common Stock,  the purchase  price is $11.98 per Comcast UK
share,  for a total equity value of  approximately  $600 million.  The Agreement
contains  provisions  such that if the purchase price per Comcast UK share falls
below $10.00, Comcast UK has the right to terminate the transaction,  subject to
NTL's right to adjust the exchange ratio such that Comcast UK shareholders would
receive $10.00 for each Comcast UK share. At September 30, 1997,  Comcast UK had
total  debt  of  approximately  $397  million,   which  is  expected  to  remain
outstanding.

     Commenting on the transaction, Barclay Knapp, President and Chief Executive
Officer, said: "This acquisition represents a significant step toward increasing
the  value  of  NTL  and   achieving  our  objective  of  becoming  the  premier
communications  company in the UK. It has always  been our  strategy to look for
acquisitions which are at attractive  values,  provide strategic benefits and do
not increase leverage, and this transaction achieves all of our objectives. With
the addition of Comcast UK's  approximately  1.6 million managed homes, NTL will
have a total of  approximately  3.8 million  managed  homes under  franchise and
increase  its local  presence by more than 75%.  The  addition  of Comcast  UK's
franchises  will also enable NTL to generate  operating  cost savings and extend
the benefits of our national telecoms network to more customers. The penetration
rates of NTL and Comcast UK are the  highest in the  industry  and the  combined
company will have more than 500,000  customers in total subscribing to more than
1,000,000  services.  We look forward to working  with  Comcast UK's  customers,
employees, and suppliers to build an outstanding communications company."

     Brian L. Roberts, President of Comcast Corporation, said, "While Comcast UK
has been a leading performer in the UK Cable and telephone  industries,  we have
determined  that long-term  success in this market will require greater size and
market  presence  than  Comcast  UK has in its asset  base.  After an  extensive
evaluation of strategic  alternatives,  we have concluded that our  shareholders
will be in the best  position to take  advantage of future growth in this market
by owning shares of NTL."

     Completion of the transaction is subject to customary  closing  conditions,
including  regulatory  approvals,  NTL and Comcast UK  shareholder  approval and
consents from their respective  bondholders.  Under certain  circumstances,  the
consideration  payable  to Comcast  shareholders  may be  adjusted  based on the
proceeds of the  potential  exercise  of certain  rights of first  refusal  with
respect to Comcast's interests in London and Birmingham.

     Comcast UK  operates  telephony/cable  networks  in the  United  Kingdom in
Cambridge  and  Teesside,  and has  interests in London  (50.0%  ownership)  and
Birmingham  (27.5%  ownership).  Comcast  UK has a total  of  approximately  1.1
million  equity  homes  under  franchise.   As  of  September  30,  1997,  on  a
proportionate basis Comcast UK had passed  approximately  660,000 homes, and had
approximately 210,000 residential telephony customers, 160,000 residential cable
television customers and 6,600 business telephony customers.

     NTL Incorporated is a leading alternative telecommunications company in the
United  Kingdom.  The Company offers local business and  residential  telephony,
residential cable television and Internet services over advanced broadband fiber
networks in six major franchise  areas in the UK. Through its national  telecoms
services  division,  the Company owns and operates one of only five  independent
national  telecoms  networks in the UK, and offers national  business  telecoms,
national and international carrier  telecommunications  services,  and satellite
and radio  communications  services.  The Company's  broadcast services division
operates a national broadcast  transmission network of more than 1,200 owned and
shared transmission sites, and offers digital and analog broadcast  transmission
services to major television and radio stations nationwide in the UK.
