Securities (as such term is defined in the respective Certificates of

Certificates of Designation for the Preferred Stock and any later filed

         3. (a) The NTL Preferred Stockholders and NTL each agree to exchange

with the qualifications, limitations and restrictions on the shares of such
series to be governed by the NTL Preferred Stock Certificate of Designation. NTL
and the NTL Preferred Stockholders each agree to effect such exchange, subject
to Section 3(b) hereof, at a closing (the "Closing") to be held at 9:00 a.m.
(New York City time) on September [ ], 2001, at the offices of Skadden, Arps,
Slate, Meagher & Flom LLP, Four Times Square, New York, New York 10036-6522 or

duly and validly endorsed for transfer to NTL free and clear of all Liens in
exchange for an equal number of shares of NTL Preferred Stock. Prior to the time

delivered to NTL at least two business days prior to the date of the Closing,
elect to retain the certificate representing the shares of Eurotel Preferred
Stock held by it. In such case, the certificate so retained shall be deemed (as
to and to the extent permitted by Delaware law) to represent, at and after the

such Exchange. An NTL Preferred Stockholder which has previously elected to
retain the certificate representing the Eurotel Preferred Stock in accordance
with this subsection may subsequently elect to receive



                                       7
<PAGE>

the certificate representing the shares of NTL Preferred Stock which such NTL
Preferred Stockholder would have received at the Closing. To receive the new
certificate representing such shares of NTL Preferred Stock, the NTL Preferred
Stockholder shall surrender its old certificate, duly endorsed for transfer or
assigned to NTL or in blank, at the principal office of NTL, with reasonable
prior written notice of that election delivered to NTL. As promptly as

Agreement by NTL will not conflict with, violate or result in the breach of any
of the material terms or conditions (whether through failure to provide notice,
lapse of time, or both) of the organizational documents of NTL, NTL Cablecom
Holding GmbH ("Cablecom") or any Cablecom Subsidiary (as such term is defined
herein).

         (d) No consent, authorization, approval, registration, qualification,
notice or waiver is required from any person or governmental authority for the

Shares upon due declaration and payment of the Dividend Shares in accordance
with the terms of the NTL Preferred Stock Certificate of Designation and the
DGCL), will be duly and validly issued and fully paid and nonassessable, free
and clear of any Liens or preemptive or other similar rights other than those
set forth in the Purchase Agreement, the Option Agreement and the Investment
Agreement. As of the date of the Closing, the shares of NTL Preferred Stock
issued hereunder will be the only shares of NTL Preferred Stock issued and
outstanding.

         (f) Assuming the accuracy of the representations and warranties of each
of the NTL Preferred Stockholders contained in Section 1 of this Agreement it is
not, and will not be, necessary in connection with the offer, sale or delivery
of the NTL Preferred Stock and the Dividend Shares to the NTL Preferred
Stockholders in the manner contemplated in this Agreement to register either the
NTL Preferred Stock or the Dividend Shares under the Securities Act.

the Qualified Holder acquiring up to 50% of the outstanding shares of Eurotel
Stock, and (x) redemption of the NTL Preferred Stock or conversion thereof into
Common Stock of NTL in accordance


                                       9

continue to be principally engaged in the businesses of providing cable
television, radio services, internet services, telephony and data services,
consumer electronics, engineering services and ownership and operation of fixed

NTL Preferred Stock Certificate of Designation to conduct, the respective
businesses of Cablecom and the Cablecom Subsidiaries in a reasonable and prudent
manner having regard to preserving the value of the exchange rights of the
Qualified Holder. So long as France Telecom and COGECOM collectively own at
least 25% of the outstanding shares of Eurotel Stock, any change of the
jurisdiction of incorporation of Eurotel shall be subject to the prior written
consent of France Telecom, which consent shall not be unreasonably withheld,
denied or delayed. In the event that NTL proposes a change of the jurisdiction
of incorporation of Eurotel, France Telecom and COGECOM agree to cooperate with
NTL and Eurotel in the discussions, planning and implementation of the change of
jurisdiction of incorporation of Eurotel, subject to the preceding sentence.
Prior to the time the France Telecom Parties exercise the conversion rights
under paragraph (9) of the NTL Preferred Stock Certificate of Designation, NTL
shall not take any acts (or omit to take any acts) that could materially
adversely affect such conversion rights, it being understood that any action
that is subject to paragraphs (9)(d) and (9)(e) of the NTL Preferred Stock
Certificate of Designation shall be deemed not to materially adversely affect
such rights.

         (h) No material agreement, contract, instrument or obligation of or
binding on NTL, Cablecom, any of the Cablecom Subsidiaries or any other
Significant Subsidiary of NTL exists as of the date hereof which would be
breached, or cause such entity to be in contravention thereof, upon consummation
of an exchange pursuant to paragraph (8) of the NTL Preferred Stock Certificate
of Designation or with respect to which consummation of an exchange pursuant to
paragraph (8) of the NTL Preferred Stock Certificate of Designation would give
rise to a right to terminate or otherwise cause a loss of any material right
thereunder, other than (i) the Cablecom Credit Facility pursuant to Section
23.13.2 thereof (provided that the Cablecom Credit Facility would not be
affected upon an exchange pursuant to paragraph (8) of the NTL Preferred Stock
Certificate of Designation if France Telecom or an affiliate thereof satisfies
at the time of such exchange the criteria for a



                                       10

permitted transferee as set forth in the definition of "Permitted Joint Venture"
in the Cablecom Credit Facility), (ii) the Transaction Agreement, with respect
to which the foregoing representation will be true if NTL retains more than 50%
ownership of the assets that are the subject thereof until March 30, 2002, and
(iii) a change of control under the redistribution licenses granted to the
Cablecom subsidiaries under the Federal Radio and Television Act.

         (i) No documentary, stamp, transfer or similar taxes will be imposed
under United States federal law or New York or Delaware state law on the initial
issuance of the NTL Preferred Stock pursuant to this Agreement, or on the
issuance and delivery of the Dividend Shares pursuant to the terms of the NTL
Preferred Stock Certificate of Designation.

         5. NTL covenants and agrees, and will cause Cablecom, the Cablecom
Subsidiaries, and any other Significant Subsidiary of NTL, not to enter into any
material agreement, contract or instrument of or binding on NTL, Cablecom, the
Cablecom Subsidiaries, or any other Significant Subsidiary of NTL or incur any
obligation after the date of issuance of the NTL Preferred Stock such that
consummation of an exchange pursuant to paragraph (8) of the NTL Preferred Stock
Certificate of Designation would cause NTL, Cablecom, the Cablecom Subsidiaries,
or any other Significant Subsidiary of NTL to be in breach or contravention of,
or give rise to a right to terminate or otherwise cause a loss of any material
right under any such agreement, contract, instrument or obligation. At any time
prior to the earlier to occur of (x) the Qualified Holder acquiring up to 50% of
the outstanding shares of Eurotel Stock and (y) redemption of the NTL Preferred
Stock or conversion thereof in accordance with the terms of the NTL Preferred
Stock Certificate of Designation, NTL covenants and agrees that it shall use
reasonable best efforts in securing terms for future material governmental
licenses, permits or authorizations to be held by Cablecom or any Cablecom
Subsidiaries such that consummation of an exchange pursuant to paragraph (8) of
the NTL Preferred Stock Certificate of Designation would not have a material
negative effect on such material governmental license, permit or authorization.

         6. Any references to the Eurotel Preferred Stock and to Eurotel in the
Purchase Agreement and any and all other agreements and documents that were
executed in connection therewith or in connection with the issuance of the
Eurotel Preferred Stock (the "Prior Agreements") shall be deemed to be
references to the NTL Preferred Stock and to Eurotel as defined in the NTL
Preferred Stock Certificate of Designation, respectively, and any references to
Eurotel Preferred Stock or Eurotel in any covenant remaining to be performed or
in any representation or


                                       11
<PAGE>

warranty in respect of the Eurotel Preferred Stock or to Eurotel shall be deemed
to be references to the NTL Preferred Stock and to Eurotel as defined in the NTL
Preferred Stock Certificate of Designation, respectively, and each of the Prior
Agreements is hereby amended in that respect and shall otherwise remain in full
force and effect. In the event of any conflict or inconsistency between the
provisions of this Agreement on the one hand and the Prior Agreements on the
other hand, the provisions of this Agreement shall govern.

         7. At or prior to the Closing, Amendment No. 3 to the Rights Agreement,
dated as of March 28, 2000, by and between NTL and Continental Stock Transfer &
