    THIS DOCUMENT IS IMPORTANT AND REQUIRES YOUR IMMEDIATE ATTENTION. THIS
DOCUMENT MUST BE READ WITH THE OFFERS TO PURCHASE/PROSPECTUS DATED MARCH 21,
1997 OF CABLE & WIRELESS COMMUNICATIONS PLC (THE "OFFERS TO PURCHASE/
PROSPECTUS") ACCOMPANYING THIS DOCUMENT. YOU ARE ALSO ENCOURAGED TO READ THE
ENCLOSED SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 ("SCHEDULE
14D-9") OF NYNEX CABLECOMMS GROUP PLC AND NYNEX CABLECOMMS GROUP INC. IF YOU ARE
IN ANY DOUBT ABOUT THE ACTION YOU SHOULD TAKE, YOU ARE RECOMMENDED TO SEEK
FINANCIAL ADVICE IMMEDIATELY FROM AN APPROPRIATELY AUTHORIZED FINANCIAL ADVISOR
OR, IF YOU ARE IN THE UNITED KINGDOM, AN INDEPENDENT FINANCIAL ADVISOR
AUTHORIZED UNDER THE FINANCIAL SERVICES ACT 1986.
 
1.  This proxy statement is being sent to holders of Units ("NYNEX CableComms
    Units"), each NYNEX CableComms Unit representing one Ordinary Share ("NYNEX
    CableComms UK Ordinary Share") of NYNEX CableComms Group PLC ("NYNEX
    CableComms UK") and one share of common stock ("NYNEX CableComms US Share of
    Common Stock") of NYNEX CableComms Group Inc. ("NYNEX CableComms US") who
    held NYNEX CableComms Units on March 21, 1997 (the "Record Date").
 
2.  As a result of differences between English law, which governs voting of
    NYNEX CableComms UK Ordinary Shares, and Delaware law, which governs voting
    of NYNEX CableComms US Shares of Common Stock:
 
    - your sale or transfer of NYNEX CableComms Units after the Record Date will
      not affect your right, as a holder on the Record Date, to attend and vote
      at the NYNEX CableComms US Special Meeting, because the right to attend
      and vote does not automatically transfer to a subsequent holder of NYNEX
      CableComms Units; and
 
    - your sale or transfer of NYNEX CableComms Units will constitute the
      transfer to a subsequent holder of the right to attend and vote at the
      NYNEX CableComms UK Extraordinary General Meeting.
 
3.  The task of obtaining votes is complicated as a result of the above
    differences. To assist NYNEX CableComms UK and NYNEX CableComms US in this
    task of obtaining votes, after carefully reviewing this document and the
    accompanying materials, YOU ARE URGED IMMEDIATELY to complete, sign, date
    and return in the enclosed pre-addressed envelope BOTH the blue Proxy Card
    for the NYNEX CableComms UK Extraordinary General Meeting AND the grey Proxy
    Card for the NYNEX CableComms US Special Meeting, even if you plan to sell
    or transfer your NYNEX CableComms Units before the meeting date. Should you
    sell or transfer your NYNEX CableComms Units after submitting the Proxy
    Cards, (i) your vote at the NYNEX CableComms US Special Meeting will be
    counted (unless you assign your right to vote to a subsequent holder and
    that holder submits a later dated Proxy Card or attends the meeting in
    person and votes) and (ii) your vote at the NYNEX CableComms UK
    Extraordinary General Meeting will be disregarded.
 
4.  If you do sell or transfer your NYNEX CableComms Units, please forward this
    document as soon as possible, together with the accompanying Offers to
    Purchase/Prospectus, Schedule 14D-9 and other accompanying documents, to the
    stockbroker, bank or other agent through whom the sale or transfer was
    effected, for transmission to the purchaser or transferee. However, these
    documents should not be distributed, forwarded or transmitted in or into
    Japan or Australia.
 
5.  Any questions or requests for assistance or additional copies of the Proxy
    Statement or the Proxy Cards may be directed to The Royal Bank of Scotland,
    Receiving Agent for the Offers in the UK (call: 0117-937-0666), or D.F. King

the "Meetings".
 
    Holders of NYNEX CableComms Units are shareholders of both NYNEX CableComms
UK and NYNEX CableComms US and are entitled to notice of and may attend both of
the Meetings.
 
    BUSINESS TO BE CONDUCTED AT THE NYNEX CABLECOMMS UK EXTRAORDINARY MEETING
AND AT ANY ADJOURNMENT(S) THEREOF:
 
    To consider and, if thought fit, pass the following resolution:
 
1.  A resolution, which will be proposed as a special resolution (the "UK
De-stapling Resolution") and, for the purposes of Article 7 of the Articles of
Association of NYNEX CableComms UK, as an extraordinary resolution of the
holders of NYNEX CableComms UK Ordinary Shares as a class (the "UK De-stapling
Resolution"):
 
    THAT, subject to the approval of the US De-stapling Resolution (as defined
    in the section of the Notice of Meetings setting out the business to be
    conducted at the Special Meeting of Shareholders of NYNEX CableComms Group
    Inc. to be held on April 24, 1997), the Articles of Association of NYNEX
    CableComms Group PLC be amended by adding a new paragraph 37(e) as follows:
 
   "(e) notwithstanding anything in these Articles to the contrary, with effect
        from the NYNEX CableComms Offers (as defined in the Offers to
        Purchase/Prospectus of Cable & Wireless Communications plc) becoming or
        being declared unconditional in all respects, the Board shall be
        empowered, in its absolute discretion, to determine that:
 
        (i)  the provisions of paragraphs (a), (b) and (d) of this Article 37;
             and
 
        (ii) any other relevant provision of these Articles restricting a
             transfer, or other dealing, of Ordinary Shares other than together
             with Common Stock of U.S. CableComms,
 
        shall not apply to the transfer, or other dealing, of such number of
        Ordinary Shares as does not exceed (when aggregated with any Ordinary
        Shares which the Board of Directors has previously permitted to be
        transferred, or otherwise dealt with, free of the restrictions of such
        provisions pursuant to this paragraph (e)) 20% of the aggregate number
        of Ordinary Shares from time to time in issue, such that those Ordinary
        Shares that the Board permits to be transferred, or otherwise dealt
        with, free of the restrictions of such provisions shall thereafter no
        longer comprise Units and shall be transferable or otherwise be dealt
        with separately and apart from the relevant Common Stock, and that the
        Board shall take all such steps and adopt and follow all such procedures
        as they may consider desirable to give effect to this paragraph."
 
2.  A resolution, which will be proposed as an ordinary resolution (the "UK
Adjournment Resolution"):
 
    THAT, if the Chairman of the meeting has determined that there are an
    insufficient number of the votes required to approve the UK De-stapling
    Resolution (as defined in the section of the Notice of Meetings setting out
    the business to be conducted at the NYNEX CableComms Group PLC Extraordinary
    General Meeting of members to be held on April 24, 1997) at the
    Extraordinary General Meeting of NYNEX CableComms Group PLC to be held on
    April 24, 1997, or any adjournment thereof, such Extraordinary General
    Meeting be, and it hereby is, adjourned to the same
 
                                       2
<PAGE>
    place and to such time, not less than seven calendar days after the date of
    such Extraordinary General Meeting, or any adjournment thereof, as the
    shareholders of NYNEX CableComms Group PLC (or the proxies therefor) may
    determine, in order to permit the obtaining of such further votes as may be
    required and further solicitations of proxies in favor of the UK De-stapling
    Resolution.
 
    BUSINESS TO BE CONDUCTED AT THE NYNEX CABLECOMMS US SPECIAL MEETING AND AT
ANY ADJOURNMENT(S) THEREOF:
 
    To consider and vote upon the following resolutions:
 
1.  Subject to the approval of the UK De-stapling Resolution, to amend the
Restated Certificate of Incorporation of NYNEX CableComms US to provide that,
notwithstanding the provisions contained in Paragraphs A and B of Article FIFTH
and other relevant provisions therein requiring that NYNEX CableComms UK
Ordinary Shares and NYNEX CableComms US Shares of Common Stock be transferred
and otherwise dealt with together as a NYNEX CableComms Unit, effective upon the
NYNEX CableComms Offers (as defined in the Offers to Purchase/Prospectus)
becoming or being declared unconditional in all respects, the Board of Directors
of NYNEX CableComms US shall be authorized to determine that such provisions
shall not apply to the transfer, conversion by way of merger or other dealing of
NYNEX CableComms US Shares of Common Stock in an amount not to exceed (when
aggregated with any NYNEX CableComms US Shares of Common Stock which the Board
of Directors has previously permitted to be transferred, converted by way of
merger or otherwise dealt with, free of the restrictions of such provisions) 20%
of the NYNEX CableComms US Shares of Common Stock from time to time outstanding,
such that those NYNEX CableComms US Shares of Common Stock that the Board of
Directors permits to be transferred, converted by way of merger or otherwise
dealt with, free of the restrictions of such provisions shall thereafter no
longer comprise NYNEX CableComms Units and shall be transferable, convertible by
way of merger or otherwise dealt with separately and apart from the relevant
NYNEX CableComms UK Ordinary Shares (the "US De-stapling Resolution").
 
2.  Subject to the approval of the UK De-stapling Resolution and the US
De-stapling Resolution, to approve and adopt the Agreement and Plan of Merger,
dated as of March 21, 1997 (the "Merger Agreement"), among NYNEX CableComms US,
Cable & Wireless Communications plc ("CWC") and Cable & Wireless Communications
Delaware Inc., a Delaware corporation ("Merger Sub"), pursuant to which Merger
Sub will be merged with and into NYNEX CableComms US (the "Merger"), and as a
result of the Merger, each outstanding NYNEX CableComms US Share of Common Stock
(other than those held by CWC or by NYNEX CableComms US (as treasury shares) or
by its subsidiaries and other than Dissenting Shares (as defined in the Merger
Agreement)) will be converted into the right to receive 0.036746 of an ordinary
share of CWC which, at the election of NYNEX CableComms US shareholders, may be
in the form of American Depositary Shares representing ordinary shares of CWC
(the "Merger Resolution").
 
3.  If the Chairman of the meeting has determined that there are an insufficient
number of the votes required to approve either the US De-stapling Resolution or
the Merger Resolution at the NYNEX CableComms US Special Meeting, or any
adjournment thereof, to adjourn the NYNEX CableComms US Special Meeting to the
same place and to such time, not less than seven calendar days after the date of
such NYNEX CableComms US Special Meeting, or any adjournment thereof, as the
shareholders of NYNEX CableComms US (or the proxies therefor) may determine, in
order to permit the obtaining of such further votes as may be required and
further solicitations of proxies in favor of the US De-stapling Resolution
and/or the Merger Resolution, as the case may be (the "US Adjournment
Resolution").
 
4.  To transact such other business as may properly come before the NYNEX
CableComms US Special Meeting or any adjournments thereof.
 
    Each of the UK De-stapling Resolution and the US De-stapling Resolution will
be voted upon separately by the shareholders of NYNEX CableComms UK and NYNEX
CableComms US, respectively;
 
                                       3
<PAGE>
however, NYNEX CableComms UK and NYNEX CableComms US will not proceed with the
amendments to the Articles of Association of NYNEX CableComms UK and the
Restated Certificate of Incorporation of NYNEX CableComms US, respectively,
unless both the UK De-stapling Resolution and the US De-stapling Resolution are
approved. In addition, NYNEX CableComms US will not proceed with the Merger
unless both the UK De-stapling Resolution and the US De-stapling Resolution are
approved.
 
    The respective Offer Committees of the Boards of Directors of each of NYNEX
CableComms UK and NYNEX CableComms US have unanimously recommended that
shareholders of NYNEX CableComms Units (and holders of American Depositary
Shares representing NYNEX CableComms Units) accept the NYNEX CableComms Offers
(as defined in the Offers to Purchase/Prospectus). The Offer Committee of the
Board of Directors of NYNEX CableComms UK has unanimously recommended approval
of the UK De-stapling Resolution to the Board of Directors of NYNEX CableComms
UK, and the Board of Directors of NYNEX CableComms UK recommends that NYNEX
CableComms UK shareholders vote in favor of the UK De-stapling Resolution and
the UK Adjournment Resolution. The Offer Committee of the Board of Directors of

Resolution and the Merger Resolution to the Board of Directors of NYNEX
CableComms US, and the Board of Directors of NYNEX CableComms US recommends that
NYNEX CableComms US shareholders vote in favor of the US De-stapling Resolution,
the Merger Resolution and the US De-stapling Resolution.

the grey proxy card is for the NYNEX CableComms US Special Meeting. Whether or
not you intend to be present at the Meetings, please sign and date BOTH of the
enclosed proxy cards and return them both in the enclosed pre-addressed
envelope.
 
1.  Only holders of NYNEX CableComms Units, or their duly appointed

entitled may appoint a proxy, who need not be a holder of NYNEX CableComms
Units, NYNEX CableComms ADSs, NYNEX CableComms UK Ordinary Shares or NYNEX
CableComms US Shares of Common Stock, to attend and vote on his/her behalf.
 
2.  Holders of NYNEX CableComms Units or NYNEX CableComms ADSs whose purchase or
transfer settles after March 21, 1997 (the "Record Date") and who wish to attend
and/or vote at the NYNEX CableComms US Special Meeting (or, in respect of NYNEX
CableComms ADSs, to instruct The Bank of New York, as Depositary, in respect of
voting at the NYNEX CableComms US Special Meeting) must arrange with the seller
or transferor to receive a validly executed assignment of proxy from the holder

copy of such power or authority), not less than 48 hours before the time of the

to NYNEX CableComms US Shares of Common Stock described in Note 2) will not
prevent a holder of NYNEX CableComms Units from attending and voting in person
at the Meetings.

                                PROXY STATEMENT
 
    This proxy statement (the "Proxy Statement") and the accompanying proxy
voting instruction cards ("Proxy Cards") are being mailed on or about March 27,
1997 to holders of Units ("NYNEX CableComms Units"), each NYNEX CableComms Unit
representing one Ordinary Share ("NYNEX CableComms UK Ordinary Share") of NYNEX
CableComms Group PLC ("NYNEX CableComms UK") and one share of Common Stock
("NYNEX CableComms US Share of Common Stock") of NYNEX CableComms Group Inc.
("NYNEX CableComms US" and, together with NYNEX CableComms UK, the "Companies")
in connection with the solicitation of proxies (or obtaining of shareholder
votes) by the Boards of Directors of the Companies for the Extraordinary General
Meeting of members of NYNEX CableComms UK (the "NYNEX CableComms UK
Extraordinary Meeting") and a Special Meeting of Shareholders of NYNEX
CableComms US (the "NYNEX CableComms US Special Meeting"), (such meetings
sometimes being hereinafter referred to, individually, as a "Meeting" and,
collectively, as the "Meetings"), each to be held on April 24, 1997 at the times
and place and for the purposes specified in the accompanying Notice of Meetings.
This proxy procedure is necessary because many of the shareholders of the
Companies will not be able to attend the Meetings. Proxies are solicited (or
votes by proxy are sought) to give all shareholders an opportunity to vote.
Shares can be voted at the Meetings only if the shareholder is represented by
proxy or is present in person (see "Voting of Shares", below).
 
    To be effective the Proxy Cards should be received at the office of The
Royal Bank of Scotland Plc, Registrars Department, PO Box 82, Caxton House,
Redcliffe Way, Bristol BS99 7YA, United Kingdom not less than 48 hours before
the time of the respective Meetings.
 
    When Proxy Cards are returned properly signed, the NYNEX CableComms Units
represented will be voted in accordance with the shareholders' directions. Votes
will be tallied by The Royal Bank of Scotland, the Registrar for the NYNEX
CableComms Units. Contrary to the usual practice in the US, the listing rules of
the London Stock Exchange require that Proxy Cards (1) provide a space for
shareholders to insert the name of their own proxy in place of the proxy
designated by the Boards of Directors of the Companies and (2) state that in the
absence of specific voting instructions as to a particular matter, such proxy
will vote or abstain at his/her discretion. Thus, if the Proxy Cards are
returned duly signed and appointing a proxy other than Mr. Blackburn, Ms. Davis,
and Mr. McConville, or, failing any of them, the chairman of the meeting, but
without an indication as to how the proxy must vote on a particular resolution,
in accordance with such listing rules of the London Stock Exchange the proxy
will vote or abstain at his/her discretion. If Mr. Blackburn, Ms. Davis, and Mr.
McConville, or, failing any of them, the chairman of the meeting is appointed as
proxy, he/she will vote for the resolutions specified as Items 1 and 2 on the
blue Proxy Card at the NYNEX CableComms UK Extraordinary Meeting and for the
resolutions specified as Items 1, 2 and 3 on the grey Proxy Card at the NYNEX
CableComms US Special Meeting, in accordance with the recommendation of the
Boards of Directors of the Companies and on any other business before the
Meetings with all the powers the shareholders would possess if personally
present; PROVIDED, HOWEVER, that no proxy that is voted against Item 1 on the
blue Proxy Card or against either of Item 1 or Item 2 on the grey Proxy Card
will be voted in favor of Item 2 on the blue Proxy Card or Item 3 on the grey
Proxy Card, respectively (if there is no indication as to how the proxy is to
vote on Item 2 on the blue Proxy Card or Item 3 on the grey Proxy Card). Proxies
voted in favor of Item 1 on the blue Proxy Card or in favor of Item 1 and Item 2
on the grey Proxy Card and proxies returned without indication as to how the
proxy is to vote on such resolutions, but in any case without an indication as
to how such proxy is to vote on Item 2 on the blue Proxy Card or Item 3 on the
grey Proxy Card, will be voted in favor of such Item.
 
    YOUR VOTE IS IMPORTANT. ACCORDINGLY, WHETHER OR NOT YOU PLAN TO ATTEND THE
MEETINGS, YOU ARE URGED TO SIGN, DATE AND RETURN BOTH OF THE ACCOMPANYING PROXY
CARDS AS SOON AS POSSIBLE IN THE ENCLOSED PRE-ADDRESSED ENVELOPE. IF YOU DO
ATTEND, YOU MAY VOTE AT THE MEETINGS THEREBY CANCELING ANY PROXY VOTE PREVIOUSLY
GIVEN, EXCEPT THAT, IF YOU HAVE EXECUTED AN IRREVOCABLE ASSIGNMENT OF PROXY WITH
RESPECT TO
<PAGE>
NYNEX CABLECOMMS US SHARES OF COMMON STOCK, YOU MAY NOT ATTEND OR VOTE AT THE
NYNEX CABLECOMMS US SPECIAL MEETING.
 
    THE MEETINGS ARE BEING HELD IN CONNECTION WITH THE TRANSACTIONS DESCRIBED IN
THE ACCOMPANYING OFFERS TO PURCHASE/PROSPECTUS OF CABLE & WIRELESS
COMMUNICATIONS PLC DATED MARCH 21, 1997 (THE "OFFERS TO PURCHASE/PROSPECTUS").
SHAREHOLDER APPROVAL OF SUCH RESOLUTIONS IS NOT A CONDITION TO ANY OF THE OFFERS
DESCRIBED IN THE OFFERS TO PURCHASE/PROSPECTUS. SHAREHOLDERS OF THE COMPANIES
ARE URGED TO READ THE ACCOMPANYING OFFERS TO PURCHASE/PROSPECTUS AND THE
COMPANIES' SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 DATED MARCH
24, 1997 (THE "SCHEDULE 14D-9").

March 21, 1997 (the "Record Date") are entitled to vote. Holders of American
Depositary Shares ("NYNEX CableComms ADSs"), each representing ten NYNEX
CableComms Units, may instruct The Bank of New York, as depositary for the NYNEX
CableComms ADSs (the "Depositary") under the Deposit Agreement dated as of June
8, 1995 (the "Deposit Agreement"), in respect of voting in accordance with
procedures established by the Depositary pursuant to the Deposit Agreement.
Holders of NYNEX CableComms Units or NYNEX CableComms ADSs whose purchase or
transfer settles after the Record Date and who wish to attend and/or vote at the
NYNEX CableComms US Special Meeting (or, in respect of NYNEX CableComms ADSs, to
instruct the Depositary in respect of voting at the NYNEX CableComms US Special
Meeting) must arrange with the seller or transferor to receive a validly
executed assignment of proxy from the holder of record on the Record Date of
NYNEX CableComms US Shares of Common Stock comprising part of such NYNEX
CableComms Units or NYNEX CableComms ADSs.
 
    On a show of hands every shareholder of NYNEX CableComms UK who is present
in person at the NYNEX CableComms UK Extraordinary Meeting shall have one vote
and on a poll every shareholder of NYNEX CableComms UK who is present in person
or by proxy shall have one vote for every NYNEX CableComms UK Ordinary Share of
which he or she is the holder. Holders of NYNEX CableComms US Shares of Common
Stock are entitled to one vote per share. With respect to NYNEX CableComms UK
Ordinary Shares and NYNEX CableComms US Shares of Common Stock represented by
NYNEX CableComms ADSs, broker non-votes (where a nominee holding shares for a
beneficial owner has not received voting instructions from the beneficial owner
with respect to a particular matter and such nominee does not possess or choose
to exercise his discretionary authority with respect thereto) will be considered
as present at the Meetings but not entitled to vote with respect to a particular
matter and will have the same effect on the vote as abstentions. See "Voting of
Shares -- NYNEX CableComms UK" and "Voting of Shares -- NYNEX CableComms US"
below.
 
    A shareholder giving a proxy has the power to revoke it at any time before
it is voted at the Meetings by submitting a written revocation to the Companies,
by the delivery of a later dated proxy duly received within the time period
specified above for delivery of proxies or by attending the Meetings and voting
at the Meetings. Holders of NYNEX CableComms ADSs may revoke voting instructions
to the Depositary only in accordance with the procedures established by the
Depositary pursuant to the Deposit Agreement. A shareholder executing an
assignment of proxy to a transferee of such shareholder's NYNEX CableComms Units
will have granted, with respect to NYNEX CableComms US Shares of Common Stock,
an irrevocable proxy coupled with an interest and may not revoke such assignment
of proxy.

quorum being present, excluding any votes of NYNEX CableComms US Shares of
Common Stock owned, directly or indirectly, by NYNEX, CWC, Bell Atlantic

<PAGE>
    Pursuant to the By-laws of NYNEX CableComms US, in order for the resolution
specified as Item 3 on the grey Proxy Card (the "US Adjournment Resolution") to
be adopted, it must receive the affirmative vote of the holders of not less than
a majority of the NYNEX CableComms US Shares of Common Stock voting either for
or against the US Adjournment Resolution in person or by proxy at the NYNEX
CableComms US Special Meeting (a quorum being present in person or by proxy).
With respect to the US Adjournment Resolution, abstentions will be included in
the total number of shares present and, therefore, will have the effect of a
negative vote.
 
    As of the Record Date, NYNEX owned, indirectly, approximately 67% of the
outstanding NYNEX CableComms US Shares of Common Stock. NYNEX has agreed with
the Companies that it will vote all of its NYNEX CableComms US Shares of Common
Stock in favor of the US De-stapling Resolution, the Merger Resolution (such
vote on the Merger Resolution, however, will not be counted for purposes of
Section 203 of the DGCL) and the US Adjournment Resolution.
 
                                     QUORUM
 
    Pursuant to Articles 7 and 59 of the NYNEX CableComms UK Articles, the
presence in person or by proxy at the NYNEX CableComms UK Extraordinary Meeting
of two or more holders of not less than one-third in nominal value of the issued
NYNEX CableComms UK Ordinary Shares shall constitute a quorum, and at any
adjourned NYNEX CableComms UK Extraordinary Meeting, two shareholders present in
person or by proxy (whatever the number of shares held by such persons) shall
constitute a quorum. The presence, in person or by proxy, of the holders of
one-third of the NYNEX CableComms US Shares of Common Stock entitled to vote at
the NYNEX CableComms US Special Meeting shall constitute a quorum for the
transaction of business. In the absence of a quorum at the time the NYNEX
CableComms US Special Meeting is convened, the holders of record of NYNEX
CableComms US present in person or by proxy may vote to adjourn the NYNEX
CableComms US Special Meeting from time to time until a quorum is obtained. The
presence, in person or by proxy, of the NYNEX CableComms US Shares of Common
Stock owned, indirectly, by NYNEX is sufficient to assure a quorum at the NYNEX
CableComms US Special Meeting.
 
                                  ADJOURNMENT
 
    Pursuant to Article 63(B) of the NYNEX CableComms UK Articles, the chairman
of the NYNEX CableComms UK Extraordinary Meeting may, with the consent of the
NYNEX CableComms UK Extraordinary Meeting at which a quorum is present (and
shall if so directed by the NYNEX CableComms UK Extraordinary Meeting), adjourn
the NYNEX CableComms UK Extraordinary Meeting from time to time and from place
to place. No business shall be transacted at any such adjourned Meeting except
business which might lawfully have been transacted at the Meeting from which the
adjournment took place. Except for an adjournment for three months or more
(which requires that notice be given as in the case of an original meeting), no
notice of any adjourned Meeting or the business to be transacted at such
adjourned Meeting is required.
 
    Pursuant to the By-Laws of NYNEX CableComms US, where a quorum is present,
the NYNEX CableComms US Special Meeting may be adjourned to another time or
place by a majority vote of the shareholders either voting for or against such
adjournment present at the NYNEX CableComms Special Meeting. Unless the Board of
Directors of NYNEX CableComms US fixes a new record date, shareholders of record
for the adjourned Meeting will be shareholders on the Record Date. If the
adjournment is for more than 30 days or if after adjournment a new record date
is fixed for the adjourned Meeting, a notice of the adjourned Meeting will be
given to each holder of record entitled to vote at the adjourned Meeting. At
such adjourned Meeting, provided that a quorum is present, any business may be
transacted that might have been transacted at the Meeting as originally called.
 
    The respective Boards of Directors of NYNEX CableComms UK and NYNEX
CableComms US have proposed the UK Adjournment Resolution and the US Adjournment
Resolution so as to adjourn the NYNEX CableComms UK Extraordinary Meeting and
the NYNEX CableComms US Special Meeting,
 
                                       4
<PAGE>
respectively, if the Chairman of the relevant meeting has determined that an
insufficient number of the votes required to approve the UK De-stapling
Resolution, and the US De-stapling Resolution or the Merger Resolution,
respectively. See "Adjournment of the NYNEX CableComms UK Extraordinary Meeting"
and "Adjournment of the NYNEX CableComms US Special Meeting".

PURCHASE/PROSPECTUS. THE COMPANIES HAVE NOT INDEPENDENTLY VERIFIED THE ACCURACY
OR COMPLETENESS OF THE INFORMATION CONTAINED IN SUCH SECTIONS, EXCEPT TO THE
EXTENT IT RELATES TO THE COMPANIES AND THEIR SUBSIDIARIES (TOGETHER, "NYNEX

    The Offers to Purchase/Prospectus states that, as announced on October 22,
1996, Cable and Wireless plc ("C&W"), Bell Canada International Inc. ("BCI") and
NYNEX have entered into an agreement (the "Transaction Agreement") under which
they agreed, subject to the satisfaction of certain conditions precedent, to
combine Mercury Communications Limited ("Mercury"), Bell Cablemedia plc ("BCM")
(as enlarged by BCM's acquisition of Videotron Holdings Plc) and the Companies
under the ownership of a newly formed holding company to be called "Cable &
Wireless Communications plc" ("CWC"). As set forth in the Offers to
Purchase/Prospectus, CWC has offered to purchase all the outstanding NYNEX
CableComms UK Ordinary Shares and NYNEX CableComms US Shares of Common Stock
(comprising NYNEX CableComms Units, including NYNEX CableComms Units represented
by NYNEX CableComms ADSs) in exchange for Ordinary Shares of 50p of CWC ("CWC

transactions described in the Offer to Purchase/Prospectus are consummated,
NYNEX CableComms will become a wholly-owned subsidiary of CWC; C&W, NYNEX and
BCI will own, directly or indirectly, approximately 52.6%, 18.5% and 14.2%,

Purchase/Prospectus accompanying this Proxy Statement. For additional
information on the background of the Companies' consideration of such
transactions and the recommendations to shareholders to accept the NYNEX
CableComms Offers, see "Item 4 -- The Solicitation or Recommendation" in the
Schedule 14D-9, which is incorporated herein by reference.
 
THE NYNEX CABLECOMMS OFFERS
 
    The Offers to Purchase/Prospectus states that CWC has offered to purchase,
upon the terms and subject to the conditions set out in the Offers to
Purchase/Prospectus and the accompanying Letter of Transmittal (including the
Notice of Guaranteed Delivery) and/or Form of Acceptance (i) all NYNEX
CableComms UK Ordinary Shares (comprising NYNEX CableComms Units, including
NYNEX CableComms Units represented by NYNEX CableComms ADSs) for 0.330714 of a
CWC Ordinary Share per NYNEX CableComms UK Ordinary Share (the "NYNEX CableComms
UK Offer") and (ii) all NYNEX CableComms US Shares of Common Stock (comprising
NYNEX CableComms Units, including NYNEX CableComms Units represented by NYNEX
CableComms ADSs) for 0.036746 of a CWC Ordinary Share per NYNEX CableComms US
Share of Common Stock (the "NYNEX CableComms US Offer") (equivalent to 0.36746
of a CWC Ordinary Share per NYNEX CableComms Unit and 3.6746 of a CWC Ordinary
Share per NYNEX CableComms ADS). (The NYNEX CableComms UK Offer and the NYNEX
CableComms US Offer are collectively referred to as the "NYNEX CableComms
Offers".)
 
                                       5
<PAGE>
    The Offers to Purchase/Prospectus states that the subsidiary of NYNEX that
holds the 67% interest in the Companies has given an irrevocable undertaking to
accept the NYNEX CableComms Offers in respect of its 67% shareholdings in the
Companies and that, pursuant to the terms of the Transaction Agreement, and upon
the Offers (as defined in the Offers to Purchase/Prospectus) becoming or being
declared unconditional, CWC will acquire from NYNEX its indirect minority
interests (including those acquired by NYNEX from certain third parties) in the
cable TV and telephony operations controlled by NYNEX CableComms in exchange for
CWC Ordinary Shares representing approximately 3.317% of the issued ordinary
share capital of CWC on a fully diluted basis.
 
    For a more complete description of the NYNEX CableComms Offers, see "Part I
- -- The Offers" contained in the Offers to Purchase/Prospectus accompanying this
Proxy Statement.
 
THE COMPULSORY ACQUISITION AND THE MERGER
 
    All the NYNEX CableComms UK Ordinary Shares and NYNEX CableComms US Shares
of Common Stock presently comprise NYNEX CableComms Units and cannot, absent the
removal or disapplication of restrictions on their transfer or other dealings,
separately or other than together as a unit ("De-stapling"), be traded,
transferred, delivered or otherwise dealt with separately.
 
    The Offers to Purchase/Prospectus states that if, on or before July 27,
1997, as a result of the NYNEX CableComms Offers or otherwise, CWC acquires or
contracts to acquire NYNEX CableComms UK Ordinary Shares (comprising NYNEX
CableComms Units, including NYNEX CableComms Units represented by NYNEX
CableComms ADSs) representing at least 90% of NYNEX CableComms UK Ordinary
Shares (comprising NYNEX CableComms Units, including NYNEX CableComms Units
represented by NYNEX CableComms ADSs) to which the NYNEX CableComms UK Offer
relates, then (i) CWC will be entitled and intends to effect a compulsory
acquisition (the "Compulsory Acquisition") to compel the purchase of the
remainder of the outstanding NYNEX CableComms UK Ordinary Shares (including
those represented by NYNEX CableComms ADSs) on the same terms as those offered
in the NYNEX CableComms UK Offer in accordance with Sections 428 -- 430F of the
Companies Act, and/or (ii) a holder of NYNEX CableComms UK Ordinary Shares
(including those represented by NYNEX CableComms ADSs) may require CWC to
purchase his or her NYNEX CableComms UK Ordinary Shares on the same terms as
those offered in the NYNEX CableComms UK Offer in accordance with Sections 430A
and 430B of the Companies Act. The acquisition of NYNEX CableComms UK Ordinary
Shares under the Compulsory Acquisition procedures of the Companies Act will
not, however, be possible unless the UK De-stapling Resolution and the US
De-stapling Resolution have been duly adopted and the respective Boards of
Directors of the Companies have taken such action as is necessary to effect the
De-stapling of the appropriate NYNEX CableComms UK Ordinary Shares and the NYNEX
CableComms US Shares of Common Stock.
 
    The Offers to Purchase/Prospectus states that, subject to the requisite
approval of NYNEX CableComms US shareholders at the NYNEX CableComms US Special
Meeting, CWC intends to become the owner of 100% of the outstanding NYNEX
CableComms US Shares of Common Stock by means of a merger (the "Merger") of
Cable & Wireless Communications Delaware Inc., a wholly-owned Delaware
subsidiary of CWC ("Merger Sub"), with and into NYNEX CableComms US, pursuant
and subject to Section 251 of the DGCL. The Offers to Purchase/Prospectus also
states that, in the Merger, NYNEX CableComms US Shares of Common Stock (other
than NYNEX CableComms US Shares of Common Stock held by NYNEX CableComms US as
treasury shares or by its subsidiaries or by CWC and other than NYNEX CableComms
US Shares of Common Stock for which appraisal rights, if any, have been properly
asserted under Section 262 of the DGCL ("Dissenting Shares"), including those
represented by NYNEX CableComms ADSs, will be converted into the right to
receive the same number of CWC Ordinary Shares as such holder of NYNEX
CableComms US Shares of Common Stock would have received in the NYNEX CableComms
US Offer with respect to its NYNEX CableComms US Shares of Common Stock. The
Offers to Purchase/Prospectus states that NYNEX CableComms US Shares of Common
Stock held by
 
                                       6
<PAGE>
NYNEX CableComms US as treasury shares, or by its subsidiaries will be canceled
in the Merger, and NYNEX CableComms US Shares of Common Stock held by CWC will
remain unchanged and outstanding (as a result of CWC's agreement to forego the
conversion of its shares of Merger Sub into shares of the surviving
corporation). The Merger is, however, subject to the Merger Resolution having
been approved by the requisite votes which are being solicited (or sought to be
obtained) by this Proxy Statement and the respective Boards of Directors of the
Companies having taken action to permit the De-stapling of the appropriate NYNEX
CableComms UK Ordinary Shares and NYNEX CableComms US Shares of Common Stock.
 
    For a more complete description of the Merger, see "Approval and Adoption of
the Merger Agreement and the Merger -- Terms of the Merger Agreement", below.
 
    All the issued and outstanding NYNEX CableComms UK Ordinary Shares and NYNEX
CableComms US Shares of Common Stock are currently "stapled" as NYNEX CableComms
Units pursuant to the provisions of the NYNEX CableComms UK Articles and the
NYNEX CableComms US Certificate requiring that NYNEX CableComms UK Ordinary
Shares and NYNEX CableComms US Shares of Common Stock be transferred or
otherwise dealt with together as a NYNEX CableComms Unit. The proposed
amendments to the NYNEX CableComms UK Articles and the NYNEX CableComms US
Certificate are being sought to permit the respective Boards of Directors to
effect the De-stapling of a certain number of NYNEX CableComms UK Ordinary
Shares and NYNEX CableComms US Shares of Common Stock comprising NYNEX
CableComms Units in order for (i) the Compulsory Acquisition procedures of
Section 428 -- 430F of the Companies Act to be applied by CWC with respect to
NYNEX CableComms UK Ordinary Shares, (ii) the Merger of NYNEX CableComms US to
occur and (iii) CWC to acquire those NYNEX CableComms UK Ordinary Shares for
which acceptances of only the NYNEX CableComms UK Offer have been received and
those NYNEX CableComms US Shares of Common Stock for which acceptances of only
the NYNEX CableComms US Offer have been received.
 
    The "stapling" of the NYNEX CableComms UK Ordinary Shares and NYNEX
CableComms US Shares of Common Stock permits the treatment of NYNEX CableComms
UK as a US corporation for US federal income tax purposes which allows NYNEX
CableComms to avoid recognition of certain taxable gains. In order to continue
this treatment of NYNEX CableComms UK as a US corporation, more than 50 per
cent. of the NYNEX CableComms UK Ordinary Shares must remain "stapled" to NYNEX
CableComms US Shares of Common Stock. In order for CWC to effect the Compulsory
Acquisition of NYNEX CableComms UK Ordinary Shares pursuant to the Companies
Act, CWC must acquire or contract to acquire at least 90 per cent. of the NYNEX
CableComms UK Ordinary Shares (comprising NYNEX CableComms Units, including
NYNEX CableComms Units represented by NYNEX CableComms ADSs). The respective
Boards of Directors of NYNEX CableComms UK and NYNEX CableComms US have
determined that the De-stapling (when aggregated with those NYNEX CableComms UK
Ordinary Shares and NYNEX CableComms US Shares of Common Stock previously
De-stapled) of up to 20% of the NYNEX CableComms UK Ordinary Shares and 20% of
the NYNEX CableComms US Shares of Common Stock outstanding would be sufficient
for the purposes of (i) effecting the Compulsory Acquisition of up to 10% of the
NYNEX CableComms UK Ordinary Shares (assuming CWC effects the Compulsory
Acquisition), (ii) effecting the Merger of NYNEX CableComms US and (iii)
permitting CWC to acquire those NYNEX CableComms UK Ordinary Shares for which
acceptances of only the NYNEX CableComms UK Offer have been received and those
NYNEX CableComms US Shares of Common Stock for which acceptances of only the
NYNEX CableComms US Offer have been received.
 
APPRAISAL RIGHTS
 
    NYNEX CableComms US shareholders do not have appraisal rights as a result of
the NYNEX CableComms Offers. In connection with the Merger, the Board of
Directors of NYNEX CableComms US has been advised that if there are at least
2,000 holders of record of NYNEX CableComms US Shares of
 
                                       7
<PAGE>
Common Stock on the Record Date, NYNEX CableComms US shareholders will not have
the right to dissent and demand an appraisal of NYNEX CableComms US Shares of
Common Stock in accordance with Section 262 of the DGCL. As of March 21, 1997,
the number of holders of record of NYNEX CableComms Units was approximately
4,948. The Board of Directors of NYNEX CableComms US has also been advised that,
if there are fewer than 2,000 holders of record on the Record Date, appraisal
rights would be available only if NYNEX CableComms ADSs which are quoted on the
Nasdaq National Market do not fall within the definition of "depository
receipts", as defined in Section 262 of the DGCL. Because the NYNEX CableComms
ADSs represent NYNEX CableComms UK Ordinary Shares, as well as the NYNEX
CableComms US Shares of Common Stock, it is not free from doubt that this
definition would be applicable. For purposes of Section 262 of the DGCL, this
Proxy Statement shall constitute notice to the record holders of NYNEX
CableComms US Shares of Common Stock that appraisal rights may be available.
 
    For a more complete description of the appraisal rights of NYNEX CableComms
US shareholders, see "Part I -- Certain Considerations -- The Compulsory
Acquisitions; the Squeeze-Out Merger; Appraisal Rights" contained in the Offers
to Purchase/Prospectus accompanying this Proxy Statement. A copy of Section 262
is set forth as Appendix VII to the Offers to Purchase/Prospectus accompanying
this Proxy Statement.
 
    NYNEX CableComms UK shareholders do not have appraisal rights with respect
to the NYNEX CableComms Offers or the Compulsory Acquisition. In the event that
the Compulsory Acquisition can be effected by CWC, however, NYNEX CableComms UK
shareholders whose NYNEX CableComms UK Ordinary Shares (including those
represented by NYNEX CableComms ADSs) have not been purchased pursuant to the
NYNEX CableComms UK Offer will be entitled to certain rights under the Companies
Act, as set forth in Appendix VI to the Offers to Purchase/Prospectus
accompanying this Proxy Statement.
 
                  SECURITY OWNERSHIP OF PRINCIPAL SHAREHOLDERS
 
    The following table sets forth, as of January 31, 1997, certain information
regarding the beneficial ownership (as defined in Rule 13d-3(d)(1) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), of NYNEX
CableComms Units by the owners of 5% or more of NYNEX CableComms Units.

controlled by NYNEX. In addition, NYNEX has the right to remove and replace the
NYNEX Appointees and such NYNEX Appointees do not stand for election by the
shareholders. NYNEX currently has indirect control of approximately 67% of the
outstanding NYNEX CableComms Units (comprising equal percentages of the issued
NYNEX CableComms UK Ordinary Shares and NYNEX CableComms US Shares of Common
Stock) and, therefore, in accordance with the NYNEX CableComms UK Articles and
the NYNEX
 
                                       8
<PAGE>
CableComms US Certificate, NYNEX is currently entitled to appoint four of the
nine current Directors of each of the Boards. Control over the appointment of
four Directors in effect gives NYNEX, through the vote of such Directors, a veto
power with respect to any actions by the Boards that require the approval of a
two-thirds vote of the Directors. This two-thirds vote requirement applies to
certain important acts of the Boards, such as the acquisition or disposal of any
business outside the ordinary course of business, the approval of the annual
budget, the approval of borrowings above L10 million, the appointment of any new
Director (other than NYNEX Appointees) to fill a vacancy and the appointment and
removal of certain Executive directors.
 
    NYNEX has the right to vote with the other shareholders in the election of
Directors for each of the remaining seats on each Board. Because NYNEX owns a
majority of the outstanding NYNEX CableComms Units, NYNEX has sufficient voting
power to elect Directors to all of the remaining seats. However, the London
Stock Exchange requires, and the constitutional documents of the Companies
provide, that at all times a majority of the Directors must be independent of
NYNEX ("Independent Directors"). In a relationship agreement with the Companies
(the "NYNEX Relationship Agreement"), NYNEX has, among other things, confirmed
its intention to vote the NYNEX CableComms UK Ordinary Shares and NYNEX
CableComms US Shares of Common Stock beneficially owned by it in a manner to
ensure, so far as it is able by the exercise of such voting rights, that a
majority of each Board is composed of Independent Directors for London Stock
Exchange purposes.
 
    Currently the Boards of the Companies each consist of four NYNEX Appointees
and five Independent Directors.
 
    Upon the Offers (as defined in the accompanying Offers to
Purchase/Prospectus) becoming or being declared unconditional, (i) CWC will
acquire all of NYNEX's NYNEX CableComms Units and as a result, pursuant to the
NYNEX CableComms UK Articles and the NYNEX CableComms US Certificate, all NYNEX
Appointees will be required to vacate immediately their positions on the
respective Boards of Directors of the Companies and (ii) pursuant to a
Shareholders Agreement among C&W, BCI, BCM Holdco Limited, Bell Canada
International Holdings Limited, NYNEX and CWC, the NYNEX Relationship Agreement
between NYNEX and the Companies will be terminated.
 
    Shareholdings of the Companies' Directors and Executive directors can be
found below.
 
             SECURITY OWNERSHIP OF DIRECTORS AND EXECUTIVE OFFICERS
 
    Certain members of senior management of the Companies have the title
"Executive director" which, under UK practice, is generally equivalent to that
of an executive officer under US practice and does not connote a position on the
Boards of Directors.
 
THE COMPANIES
 
    The following table sets forth, as of January 31, 1997, beneficial ownership
(as defined in Rule 13d-3(d)(1) under the Exchange Act) of NYNEX CableComms
Units by each Director, each named Executive director and all Directors and
Executive directors (as a group), including NYNEX CableComms Units of which they
had the right within 60 days to acquire beneficial ownership pursuant to the
exercise of options to purchase NYNEX CableComms Units.

    NYNEX has entered into an Amended and Restated Agreement and Plan of Merger
dated as of April 21, 1996, as amended as of July 2, 1996, with Bell Atlantic,
pursuant to which a wholly-owned subsidiary of Bell Atlantic will merge with and
into NYNEX and NYNEX will become a wholly-owned subsidiary of Bell Atlantic. In
the merger, each shareholder of NYNEX will receive 0.768 shares of Bell Atlantic
common stock in exchange for one share of NYNEX Common Stock.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Effective on June 14, 1995, the Companies and NYNEX CableComms Limited, an
indirect wholly-owned subsidiary of the Companies which provides substantially
all the management, operations and other business functions for the Companies,
entered into a trademark agreement with NYNEX under which the Companies and
NYNEX CableComms Limited are required to pay L4.0 million per annum for 5 years
for use of the "NYNEX" name. Upon the Offers (as defined in the accompanying
Offers to Purchase/ Prospectus) becoming or being declared unconditional, the
trademark agreement will be replaced by a
 
                                       11
<PAGE>
transitional license between NYNEX and CWC ("the NYNEX Transitional License")
providing for CWC's right to use the "NYNEX" name for a transitional period. For
a description of the NYNEX Transitional License, see "Part II -- Description of
CWC -- Principal Shareholders -- NYNEX Transitional License" contained in the
Offers to Purchase/Prospectus accompanying this Proxy Statement.
 
    Effective on June 14, 1995, the Companies and NYNEX CableComms Limited
entered into a services and technology sharing agreement with NYNEX pursuant to
which NYNEX provides certain services to the Companies and NYNEX CableComms
Limited. This agreement covers both the scope and method of calculation of the
cost of such services. The level of charges under this agreement is intended to
arrive at arm's length transaction costs. Payments to NYNEX under the services
agreement totaled L5.0 million and L2.6 million for 1996 and 1995, respectively.
Upon the Offers becoming or being declared unconditional, the services agreement
will be terminated and the Offers to Purchase/Prospectus states that C&W, BCI,
NYNEX and CWC will enter into a management and technical services agreement (the
"Management and Technical Services Agreement") pursuant to which each of C&W,
BCI and NYNEX will provide various services to CWC at CWC's request (including
tax, legal, treasury and corporate finance and human resources) and CWC may
provide to each of C&W, BCI and NYNEX accounting and car fleet management
services. For a description of the Management and Technical Services Agreement,
see "Part II -- Description of CWC -- Principal Shareholders -- Management and
Technical Services Agreement" contained in the Offers to Purchase/Prospectus
accompanying this Proxy Statement.
 
    The Companies and NYNEX CableComms Limited also entered into a secondment
agreement with NYNEX which provides that NYNEX will, subject to certain
conditions, continue to second employees to the Companies and their subsidiaries
upon the request of the Companies. The Companies have agreed to reimburse NYNEX
for all costs NYNEX incurs in respect of any personnel so seconded. Currently,
11 of the senior management of NYNEX CableComms Limited are on secondment from
NYNEX, including Messrs. Hatch, Doherty, McHale, Repp, Schieck and Welsh who are
Executive directors of NYNEX CableComms Limited. Mr. Repp is also a Director of
NYNEX CableComms Limited. Under the secondment agreement, NYNEX was reimbursed
by the Companies in the aggregate of L1.6 million and L2.7 million for such
secondees during 1996 and 1995, respectively. Upon the Offers becoming or being
declared unconditional, the secondment agreement will be terminated (except as
to persons then on secondment) and the Offers to Purchase/Prospectus states that
C&W, BCI, NYNEX and CWC will enter into a secondment agreement (the "Secondment
Agreement") pursuant to which each of C&W, BCI and NYNEX, on the one hand, and
CWC, on the other hand, will, subject to certain conditions, be able to second
their employees or employees of their subsidiaries to each other, respectively,
or to companies within their respective groups. For a description of the
Secondment Agreement, see "Part II -- Description of CWC -- Principal
Shareholders -- Secondment Agreement" contained in the Offers to Purchase/
Prospectus accompanying this Proxy Statement.
 
    The Companies and Mr. Mearing-Smith (the Chief Financial Officer and
Director of the Companies, who delegated his duties as Chief Financial Officer
as of January 30, 1997) were party to an agreement which terminated Mr.
Mearing-Smith's right of first refusal and right to deferred consideration with
respect to his interest in certain franchises purchased by the Companies in
exchange for consideration which consisted of grants of NYNEX CableComms Units
and cash approximately equal in value to the deferred consideration. Under the
agreement, Mr. Mearing-Smith received L440,000 in cash in 1995 and 270,406 NYNEX
CableComms Units in 1996.
 
    Approximately 67% of the outstanding NYNEX CableComms Units are held by an
indirect, wholly-owned subsidiary of NYNEX. The Companies, through various
wholly-owned subsidiaries and two partnerships in which they exercise management
control and hold a majority interest, control the exercise of all the voting
rights in the 16 companies that hold the licenses in the Companies' franchise
areas (the "Operating Companies"). Other wholly-owned subsidiaries of NYNEX have
direct and indirect equity interests in lenders to the Operating Companies and
indirect equity interests in the Operating Companies separate from NYNEX's
interest as a shareholder of the Companies. This includes indirect equity
interests
 
                                       12
<PAGE>
in the two limited partnerships (the "North Partnership" and the "South
Partnership") which own substantially all of the ordinary shares of the
Operating Companies. The lenders to the Operating Companies hold (in addition to
loans to the Operating Companies) limited partnership interests in the North
Partnership and the South Partnership. Under the partnership agreements, the
limited partners generally have a 15% interest in all items of income, gain,
loss deduction or credit, except in respect of initial losses and profits (being
specified amounts of profits or losses calculated in accordance with US tax
principles) of the relevant partnership.
 
    Initial losses up to a maximum cumulative amount of L200.0 million in the
case of the North Partnership and L40.0 million in the case of the South
Partnership will be allocated to the limited partners, respectively. After that,
losses will be allocated to NYNEX CableComms up to the point that NYNEX
CableComms' share of the cumulative losses of the relevant partnership reaches
85%. At that point, any further losses will be allocated 85% to NYNEX CableComms
and 15% to the limited partners. Initial profits will be allocated between NYNEX
CableComms and the limited partners in proportion to the cumulative losses
allocated to each partner until such losses have been fully offset by profits.
Thereafter, all profits are to be allocated 85% to NYNEX CableComms and 15% to
the limited partners. Initial losses for the South Partnership reached L40.0
million in the first quarter of 1996. Initial losses for the North Partnership
have not yet reached L200.0 million.
 
    For the purposes of preparing the combined financial statements, the profit
or loss of the relevant partnership is allocated between NYNEX CableComms and
the limited partners in accordance with the profit and loss allocations set out
in the relevant partnership agreement.
 
    The limited partners had contributed L211.7 million to the North Partnership
and to the South Partnership as of both December 31, 1995 and December 31, 1996.
Minority interests of the limited partners in the North Partnership and the
South Partnership were L18.8 million and L57.8 million, respectively, at
December 31, 1996, and L76.2 million and L55.9 million, respectively at December
31, 1995.
 
    The North Partnership and the South Partnership are included in NYNEX
CableComms' US GAAP combined financial statements. The limited partners are
entitled to distributions only if declared and their capital contributions in
the North Partnership and the South Partnership, respectively, are reflected in
NYNEX CableComms' US GAAP combined financial statements under "Minority
interest". The revolving loans from the limited partners to the Northern
Operating Companies and Southern Operating Companies are reflected in NYNEX
CableComms' US GAAP combined financial statements under "Long-term debt".
 
    The Northern Operating Companies borrowed L292.9 million and L96.5 million
under the revolving credit facilities from the limited partners at December 31,
1996 and December 31, 1995, respectively. The Southern Operating Companies
borrowed L154.8 million and L28.9 million under the revolving credit facilities
from the limited partners at December 31, 1996 and December 31, 1995,
respectively. Neither the North Partnership nor the South Partnership had made
any borrowings under the revolving credit facilities from the limited partners
at December 31, 1996 or December 31, 1995.
 
    Interest and fees paid to the lenders under the revolving credit facilities
for the years ended December 31, 1996 and December 31, 1995 aggregated L14.6
million and L6.5 million, respectively, for the Northern Operating Companies and
L7.5 million and L8.7 million, respectively, for the Southern Operating
Companies.
 
                                       13
<PAGE>
    The revolving loans are unsecured obligations of the Operating Companies.
However, the Companies have pledged their interests in the North Partnership and
the South Partnership as collateral for repayment of the Northern Operating
Companies' and the Southern Operating Companies' revolving loans, respectively,
and significant restrictions exist on the rights of the Operating Companies to
encumber any assets or incur any additional indebtedness.
 
    The Companies have certain rights to purchase the equity interests held by
the limited partners in the North Partnership and the South Partnership. The
purchase option provides for the acquisition of these equity interests at a
price equal to fair market value, but in no event less than the unrecovered
investment of the limited partners. Under certain circumstances, following the
occurrence of certain adverse events, the failure to purchase the limited
partner's interest could result in a liquidation of the North Partnership and
the South Partnership.
 
    The Offers to Purchase/Prospectus states that both of the revolving credit
facilities for the Northern Operating Companies and the Southern Operating
Companies will be terminated upon the Offers becoming or being declared
unconditional. See "Part II -- Description of CWC -- Liquidity and Capital
Resources" of the Offers to Purchase/Prospectus for a discussion of CWC's credit
facilities.
 
    The Operating Companies have entered into two forward sterling interest rate
swaps with NYNEX to reduce potential exposure to interest rate risks inherent in
the financing arrangements for the Northern Operating Companies and Southern
Operating Companies. Under the interest rate swaps, the Companies agreed to
exchange with NYNEX, on a quarterly basis, the difference between fixed-rate
(9.15% for the Northern financing arrangement and 7.02% for the Southern
financing arrangement) and floating-rate 3-month Sterling LIBOR interest amounts
calculated by reference to an agreed notional principal amount. The notional
principal amounts of the swaps are L700.0 million and L273.7 million for swaps
entered into on December 19, 1994 and December 31, 1993, respectively. The net
effect of the interest rate swap is to fix the net cash outflow of the Companies
to 9.15% and 7.02% of the appropriate financing arrangement. In order to
correspond to the underlying financing arrangements for the Northern Operating
Companies and Southern Operating Companies, the effective date of the swaps is
the first payment date after the earlier of five years from commencement of the
arrangements or the date all completion requirements are met, and expire by
December 31, 2004 and 2003, respectively.
 
    In addition, the Operating Companies have entered into two agreements with
NYNEX to reduce the notional amount of the interest rate swaps at the Operating
Companies' option. The notional amount may be reduced at any time, and from time
to time, in whole or in part, without any penalty or additional payments. The
effective dates and expiration dates of these options are the same as the swap
transactions. The Operating Companies paid premiums of L18.3 million and L7.0
million in respect of the Northern and Southern financing arrangements,
respectively, which are being amortized over the life of the options.
 
    NYNEX has entered into the credit facility with NYNEX CableComms, to make
available up to L200 million (the "NYNEX Facility"). NYNEX CableComms may make
drawings under the NYNEX Facility at any time before May 31, 1997. Amounts
borrowed are to be repaid in full by May 31, 1998. The rate of interest
applicable to amounts drawn under the NYNEX Facility is three month sterling
LIBOR plus 4%. NYNEX CableComms paid NYNEX a fee of L375,000 during 1996 for
NYNEX's commitment to provide the NYNEX Facility. No drawings have yet been made
on the NYNEX Facility. The Offers to Purchase/ Prospectus states that the NYNEX
credit facility will be terminated upon the Offers becoming or being declared
unconditional.
 
    NYNEX has entered into an agreement with the Companies whereby it has agreed
to indemnify the Companies for certain US and UK tax liabilities of NYNEX and
its affiliates (including the affiliates that were transferred to the Companies
as part of a reorganization of NYNEX's cable television and telecommunications
operations in the UK effected immediately prior to the Companies' initial public
offering on June 14, 1995 ("the Combined Offering")) arising from or
attributable to periods prior to the
 
                                       14
<PAGE>
completion of the Combined Offering. Such tax indemnification arrangement will
remain in place after the acquisition by CWC of NYNEX's 67% interest in NYNEX
CableComms.
 
    Prior to June 14, 1995, the Companies' US corporations were included in the
NYNEX consolidated US federal tax return and in New York State and New York City
combined income tax filings. While included in the NYNEX tax filings, the
Companies' US corporations were allocated payments in accordance with the effect
their losses had on reducing the consolidated group's taxable income. As a
result of the reorganization which occurred immediately prior to the completion
of the Combined Offering, the Companies and their US corporations no longer
qualify to be included in the NYNEX consolidated US federal tax return or in any
state or local combined tax returns. As such, any equivalent payments will no
longer be made to the Companies by NYNEX for any future losses generated. For
periods after June 14, 1995, NYNEX U.K. CableComms Holdings, Inc. (" NYNEX UK
Holdings") and its US subsidiaries will be treated as a consolidated group of
corporations for US tax return purposes. However, neither NYNEX CableComms UK
nor NYNEX CableComms US will be consolidated with NYNEX UK Holdings or its
subsidiaries for US tax purposes. As a result, NYNEX CableComms UK and NYNEX
CableComms US will file their own US federal tax returns separately from NYNEX
UK Holdings.
 
    On May 15, 1995, the Companies and NYNEX entered into a registration rights
agreement pursuant to which, subject to compliance with London Stock Exchange
requirements and subject to certain other exceptions, NYNEX has the right, at
its own expense, (i) to require the Companies to include all or any portion of
the NYNEX CableComms Units beneficially owned by NYNEX or its affiliates in any
registered offering by any of the Companies in the United States (or in any
prospectus for the offering and sale to the public in the United Kingdom) and
(ii) for ten years beginning one year after the initial public offering, to
cause the Companies on up to two separate occasions to file a registration
statement for an offering in the United States and to take such other action to
facilitate an offering and sale in the United Kingdom.

its affiliates and CWC and its affiliates (including C&W), see "Part II --
Description of CWC -- Principal Shareholders" contained in the Offers to

TERMS OF THE MERGER AGREEMENT
 
    The following summary of certain provisions of the Merger Agreement, a copy
of which is attached as Appendix I to this Proxy Statement, is qualified in its
entirety by reference to the text of the Merger Agreement, which is incorporated
herein by reference.
 
                                       18
<PAGE>
    THE MERGER
 
    At the effective time of the Merger (the "Effective Time"), NYNEX CableComms
US and Merger Sub will consummate the Merger whereby Merger Sub will merge with
and into NYNEX CableComms US and the separate corporate existence of Merger Sub
will thereupon cease. NYNEX CableComms US will be the surviving corporation (the
"Surviving Corporation") in the Merger and will continue its corporate existence
under the name "NYNEX CableComms Group Inc." The Merger Agreement provides that
the NYNEX CableComms US Certificate and the NYNEX CableComms US By-Laws in
effect at the Effective Time will continue as the certificate of incorporation
and the by-laws of the Surviving Corporation. The directors of Merger Sub will
become the directors of the Surviving Corporation and the officers of NYNEX
CableComms US will become the officers of the Surviving Corporation.
 
    In the Merger, at the Effective Time, the shares of Merger Sub Common Stock
outstanding immediately prior to the Effective Time will be converted into and
will become the number of shares of Common Stock of the Surviving Corporation
equal to the number of CWC-Owned Shares (as defined below) at the Effective
Time; PROVIDED, HOWEVER, that the sole shareholder of Merger Sub, may, in its
discretion, waive its rights to have the shares of Merger Sub Common Stock
converted and such shares of Merger Sub Common Stock will cease to be
outstanding and will be canceled and retired and, in consideration therefor,
NYNEX CableComms US Shares of Common Stock owned by such shareholder of Merger
Sub that would otherwise be canceled shall be retained by such shareholder, on a
share-for-share basis, as the shares of common stock of the Surviving
Corporation (as described below).
 
    Pursuant to the Merger Agreement, at the Effective Time each issued and
outstanding NYNEX CableComms US Share of Common Stock (other than (i) any NYNEX
CableComms US Shares of Common Stock held by NYNEX CableComms US or its
subsidiaries, (ii) CWC-Owned Shares or (iii) Dissenting Shares (as defined
below)) (the "Shares") will be converted into one of the following (the "Merger
Consideration"): (a) for each such Share with respect to which an election to
receive solely CWC ADSs has been effectively made and not revoked (an "ADS
Election"), the right to receive 0.007349 of a CWC ADS or (b) for each such
Share with respect to which an ADS Election has not been effectively made or has
been revoked, the right to receive 0.036746 of a CWC Ordinary Share (the "Stock
Consideration").
 
    As a result of the Merger and without any action on the part of the holder
thereof, at the Effective Time, all Shares will cease to be outstanding and will
be canceled and retired and will cease to exist, and each such holder of Shares
will thereafter cease to have any rights with respect to such Shares, except the
right to receive, without interest, either (A) the Stock Consideration, in the
form of CWC Ordinary Shares and cash in lieu of fractional CWC Ordinary Shares,
or (B) the ADS Consideration, in the form of whole CWC ADSs and, in lieu of
fractional CWC ADSs, CWC Ordinary Shares and cash in lieu of fractional CWC
Ordinary Shares upon the surrender of (i) a certificate for NYNEX CableComms
Units (a "Unit Certificate") evidencing such Shares (and an equal number of
NYNEX CableComms UK Ordinary Shares) or (ii) if the NYNEX CableComms US Shares
of Common Stock and NYNEX CableComms UK Ordinary Shares comprising such NYNEX
CableComms Units shall have been De-stapled and a certificate for NYNEX
CableComms US Shares of Common Stock (a "Share Certificate") representing such
Shares shall have been issued prior to the Effective Time, such Share
Certificate. For the purposes of determining whole CWC Ordinary Shares and whole
CWC ADSs, if a Compulsory Acquisition of NYNEX CableComms UK Ordinary Shares
shall have been effected on or about the Effective Time, the consideration that
holders are entitled to receive as a result of Compulsory Acquisition of the
NYNEX CableComms UK Ordinary Shares will be taken into account. Each NYNEX
CableComms US Share of Common Stock issued and held as treasury shares of NYNEX
CableComms US or held by any subsidiary of NYNEX CableComms US immediately prior
to the Effective Time will, by virtue of the Merger, cease to be outstanding and
will be canceled and retired without payment of any consideration therefor.
 
    Each issued and outstanding NYNEX CableComms US Share of Common Stock owned
by CWC ("CWC-Owned Shares") immediately prior to the Effective Time will, by
virtue of the Merger, cease to be
 
                                       19
<PAGE>
outstanding and will be canceled and retired without payment of any
consideration therefor; PROVIDED, HOWEVER, that notwithstanding the foregoing,
if CWC waives its rights with respect to the conversion of the shares of Merger
Sub Common Stock into shares of the Surviving Corporation as provided in the
Merger Agreement, in consideration of such waiver such CWC-Owned Shares will
continue to be outstanding to the maximum extent permitted by law and will
represent, on a share-for-share basis, the shares of common stock of the
Surviving Corporation. CWC has agreed to waive its rights to have the shares of
Merger Sub Common Stock converted and to have such shares canceled and retired
in consideration for having the CWC-Owned Shares continue to be outstanding and
represent the shares of common stock of the Surviving Corporation.
 
    NYNEX CableComms US Shares of Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by stockholders who
have not voted such NYNEX CableComms US Shares of Common Stock in favor of the
Merger and who have properly exercised their rights of appraisal (if any) for
such NYNEX CableComms US Shares of Common Stock in the manner provided by
Section 262 of the DGCL (the "Dissenting Shares") will not be converted into or
be exchangeable for the right to receive the Merger Consideration, unless such
holder fails to perfect or effectively withdraws or loses his right to appraisal
and payment (if any), as the case may be. If such holder so fails to perfect or
effectively withdraws or loses such right (if any), his shares will thereupon be
deemed to have been converted into and to have become exchangeable for, at the
Effective Time, the right to receive the Merger Consideration.
 
    The Merger Agreement provides that each person who, at the Effective Time,
is a record holder of Shares will have the right to submit an election form
specifying the number of Shares that such person desires to have converted into
the right to receive CWC ADSs pursuant to an ADS Election. As of the Effective
Time, CWC will (i) deposit with a bank or trust company designated by CWC and
reasonably acceptable to NYNEX CableComms US (the "Exchange Agent"),
certificates representing the CWC Ordinary Shares ("CWC Certificates") and (ii)
deposit with Citibank, N.A., as Custodian and Depositary, CWC Certificates and
will cause the Depositary to issue and deposit with the Exchange Agent, American
Depositary Receipts evidencing CWC ADSs ("CWC ADRs"). CWC Ordinary Shares or CWC
ADSs, as the case may be, into which Shares will be converted pursuant to the
Merger, as well as CWC Ordinary Shares represented by such CWC ADSs, will be
deemed to have been issued at the Effective Time.
 
    Notwithstanding any other provisions of the Merger Agreement, no dividends
or other distributions declared after the Effective Time on CWC Ordinary Shares
or CWC ADSs, as the case may be, will be paid with respect to any Shares which,
prior to the Effective Time, were represented by a Unit Certificate or Share
Certificate, as the case may be, until such Unit Certificate or Share
Certificate, as the case may be, is surrendered for exchange. Subject to the
effect of applicable laws, following surrender of any such Unit Certificate or
Share Certificate, as the case may be, there will be paid to the holder of the
CWC Ordinary Shares or CWC ADSs, as the case may be, represented by CWC
Certificates or CWC ADRs delivered in exchange 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 payable with respect to
such whole CWC Ordinary Shares or CWC ADSs, as the case may be, and not paid,
less the amount of any withholding taxes which may be required thereon, and (ii)
at the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender and a payment
date subsequent to surrender payable with respect to such whole CWC Ordinary
Shares or CWC ADSs, as the case may be, less the amount of any withholding taxes
which may be required thereon.
 
    No fractional CWC Ordinary Shares or fractional CWC ADSs will be issued
pursuant to the Merger. Instead, the Merger Agreement provides that in lieu of
the issuance of any fractional CWC Ordinary Shares in the Merger, fractional CWC
Ordinary Shares will be aggregated and sold in the market and the net proceeds
of sale distributed pro rata to holders of NYNEX CableComms US Shares of Common
Stock who would otherwise be entitled to receive fractional CWC Ordinary Shares.
The Merger Agreement further provides that in lieu of the issuance of any
fractional CWC ADSs in the Merger holders of Shares
 
                                       20
<PAGE>
who would otherwise be entitled to receive fractional CWC ADSs will be entitled
to receive a CWC Certificate representing such whole number of CWC Ordinary
Shares represented by such fractional CWC ADS and will be paid a cash adjustment
for any fractional CWC Ordinary Share represented by such fractional CWC ADS in
the manner described above, in each case less the amount of any withholding
taxes which may be required thereon.
 
    CONDITIONS TO THE MERGER
 
    The Merger Agreement provides that the respective obligations of each party
to effect the Merger is subject to the satisfaction at or prior to the Effective
Time of (i) the US De-stapling Amendments, the Merger Agreement and the Merger
having been approved and adopted by the requisite votes of the shareholders of
NYNEX CableComms US; (ii) the UK De-stapling Amendments having been approved by
the requisite votes of the shareholders of NYNEX CableComms UK; (iii) the NYNEX

the US De-stapling Amendments, the Boards of Directors of NYNEX CableComms UK
and NYNEX CableComms US having taken such action, in their absolute discretion,
as is necessary to permit the De-stapling of up to 20% of the outstanding NYNEX
CableComms UK Ordinary Shares and NYNEX CableComms US Shares of Common Stock.
 
    EFFECTIVE TIME

Merger with the Secretary of State of the State of Delaware or (ii) such other

in such certificate of merger.
 
    TERMINATION
 
    Notwithstanding the approval and adoption of the Merger Agreement by the
stockholders of NYNEX CableComms US and Merger Sub, respectively, the Merger
Agreement will terminate forthwith in the event that the Transaction Agreement

    SURRENDER OF UNIT CERTIFICATES
 
    As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail to each holder of record of Shares immediately prior to the
Effective Time (i) a Letter of Transmittal, (ii) instructions for use in
effecting the surrender of Unit Certificates or Share Certificates, as the case
may be, in exchange for the Merger Consideration with respect to the Shares and
(iii) an election form providing for such holders to make the ADS Election. All
holders of Shares immediately prior to the Effective Time that have not
submitted to the Exchange Agent, or have properly revoked, an effective,
properly completed election form to make the ADS Election will receive the Stock
Consideration.
 
    An ADS Election is validly made only if the Exchange Agent has received an
election form properly completed and executed by such holder accompanied by such
holder's Unit Certificates or Share Certificates, as the case may be.
 
    Upon surrender of a Unit Certificate or Share Certificate, as the case may
be, for cancellation to the Exchange Agent, together with the Letter of
Transmittal duly executed, and such other documents as CWC or the Exchange Agent
shall reasonably request, the holder of such Unit Certificate or Share
Certificate, as the case may be, will be entitled to receive as soon as
practicable after the Effective Time in exchange therefor (i) with respect to
Shares represented by such Unit Certificate or Share Certificate, as the case
may be, with respect to which an ADS Election has not been effectively made or
has been revoked (a) (1) a
 
                                       21
<PAGE>
CWC Certificate representing that number of whole CWC Ordinary Shares, if any,
which such holder has the right to receive and (2) a certified or bank cashier's
check in the amount equal to the cash in lieu of fractional CWC Ordinary Shares,
if any, or (ii) with respect to Shares represented by such Unit Certificate or
Share Certificate, as the case may be, with respect to which an ADS Election has
been effectively made and not revoked, CWC ADRs evidencing that number of whole
CWC ADSs, if any, which such holder has the right to receive and in lieu of
fractional CWC ADSs, a CWC Certificate representing that number of whole CWC
Ordinary Shares represented by the fractional CWC ADS and a certified or bank
cashier's check in the amount equal to the cash in lieu of fractional CWC
Ordinary Shares represented by the fractional CWC ADS, if any, in each case less
the amount of any required withholding taxes. In addition, if a Compulsory
Acquisition of such NYNEX CableComms UK Ordinary Shares shall have been
effected, but the holder has not theretofore received the consideration that
such holder is entitled to receive pursuant to the Compulsory Acquisition, upon
surrender of such holder's Unit Certificate such holder shall receive such
consideration that such holder is entitled to pursuant to the Compulsory
Acquisition, provided that such holder has complied with the applicable
requirements of the Companies Act with respect to the Compulsory Acquisition.
The Unit Certificate or Share Certificate, as the case may be, so surrendered
shall forthwith be canceled. Until surrendered, each Unit Certificate or Share
Certificate, as the case may be, shall be deemed at any time after the Effective
Time to represent only the right to receive the Merger Consideration with
respect to the Shares formerly represented thereby and, with respect to a Unit
Certificate only, if a Compulsory Acquisition shall have been effected, any
consideration payable with respect to the NYNEX CableComms UK Ordinary Shares
formerly represented thereby subject to the Compulsory Acquisition.

    Pursuant to the Merger Agreement, NYNEX CableComms US has agreed to use its
reasonable best efforts to cause each individual holder of NYNEX CableComms US
Shares of Common Stock reasonably believed by NYNEX CableComms US to be an

    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE
 
    CWC has agreed in the Merger Agreement that the Certificate of Incorporation
and the By-Laws of the Surviving Corporation will contain provisions with
respect to indemnification not less favorable to the directors and officers than
those set forth in the NYNEX CableComms US Certificate and By-Laws of NYNEX
CableComms US on the date of the Merger Agreement, which provisions shall not be
amended, repealed or otherwise modified for a period of six years after the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who at the Effective Time were directors or officers of NYNEX
CableComms US in respect of actions or omissions occurring at or prior to the
Effective Time (including, without limitation, the transactions contemplated by
the Merger Agreement), unless such modification is required by law. CWC shall
guarantee the foregoing obligations of the Surviving Corporation.
 
    In addition, the Merger Agreement provides that CWC will cause the Surviving
Corporation to use its reasonable best efforts to maintain in effect for six
years from the Effective Time, if available, the coverage provided by the
current directors' and officers' liability insurance policies maintained by
NYNEX (provided that the Surviving Corporation may substitute therefor policies
of at least the same coverage containing terms and conditions which are not
materially less favorable) with respect to matters occurring prior to the
Effective Time.
 
    The Merger Agreement provides that the provisions described above will
survive the Effective Time, and are intended to be for the benefit of, and shall
be enforceable by, the directors and officers of NYNEX CableComms US and shall
be binding on CWC and Merger Sub and the Surviving Corporation and their
respective successors and assigns.

                              CONVERSION OF SHARES
 
    SECTION 2.1.  MERGER SUB COMMON STOCK.  At the Effective Time, the shares of
Merger Sub Common Stock outstanding immediately prior to the Effective Time
shall be converted into and shall become the number of shares of common stock of
the Surviving Corporation equal to the number of CWC-Owned Shares (as defined in
Section 2.2(b)) at the Effective Time; PROVIDED, HOWEVER, that the shareholder
of Merger Sub, may, in its discretion, waive its rights to have the shares of
Merger Sub Common Stock converted as provided in this Section 2.1 and such
shares of Merger Sub Common Stock shall cease to be outstanding and shall be
canceled and retired and in consideration therefor, the shares of NYNEX
CableComms US owned by such shareholder of Merger Sub that would otherwise be
canceled pursuant to Section 2.2(b) shall be retained by such shareholder, on a
share-for-share basis, as shares of common stock of the Surviving Corporation,
as provided in Section 2.2 (b).
 
    SECTION 2.2.  CONVERSION OF NYNEX CABLECOMMS US SHARES.
 
    (a) Subject to Sections 2.2(c) and 2.2(d), at the Effective Time, each
issued and outstanding NYNEX CableComms US Share of Common Stock, other than any
NYNEX CableComms US Shares of Common Stock to be canceled or otherwise dealt
with pursuant to Section 2.2 (b), Section 2.2 (c) or Dissenting Shares (as
defined in Section 2.2 (d)) (the "Shares") shall be converted into one of the
following (the "Merger Consideration"):
 
        (i) for each such Share with respect to which an election to receive
    solely American Depositary Shares (the "CWC ADSs") representing Ordinary
    Shares of 50p each of CWC (the "CWC Ordinary Shares") has been effectively
    made and not revoked pursuant to Sections 2.3(c), (d) and (e) (an "ADS
    Election"), the right to receive 0.007349 of a CWC ADS (the "ADS
    Consideration"); or
 
        (ii) for each such Share with respect to which an ADS Election has not
    been effectively made or has been revoked pursuant to Sections 2.3(c), (d)
    and (e), the right to receive 0.036746 of a CWC Ordinary Share (the "Stock
    Consideration").
 
    As a result of the Merger and without any action on the part of the holder
thereof, at the Effective Time, all Shares shall cease to be outstanding and
shall be canceled and retired and shall cease to exist, and
 
                                       2
<PAGE>
each such holder of Shares shall thereafter cease to have any rights with
respect to such Shares, except the right to receive, without interest, either
(A) the Stock Consideration, in the form of CWC Ordinary Shares and cash in lieu
of fractional CWC Ordinary Shares, or (B) the ADS Consideration, in the form of
whole CWC ADSs and, in lieu of fractional CWC ADSs, CWC Ordinary Shares and cash
in lieu of fractional CWC Ordinary Shares upon the surrender of (i) a
certificate for Units (a "Unit Certificate") evidencing such Shares (and an
equal number of NYNEX CableComms UK Ordinary Shares) or (ii) if the NYNEX
CableComms US Shares of Common Stock and NYNEX CableComms UK Ordinary Shares
comprising such Units are permitted to be transferred, converted by way of
merger or otherwise dealt with other than as Units and a certificate for NYNEX
CableComms US Shares of Common Stock (a "Share Certificate") representing such
Shares shall have been issued prior to the Effective Time, such Share
Certificate. For the purposes of determining whole CWC Ordinary Shares and whole
CWC ADSs, if a Compulsory Acquisition of NYNEX CableComms UK Ordinary Shares
shall have been effected, the consideration that such holder is entitled to
receive as a result of the compulsory acquisition ("Compulsory Acquisition") of
such NYNEX CableComms UK Ordinary Shares under Sections 428 to 430F of the
Companies Act 1985 of Great Britain, as amended (the "Companies Act"), will be
taken into account.
 
    (b) Notwithstanding anything contained in this Section 2.2 to the contrary,
each issued and outstanding NYNEX CableComms US Share of Common Stock owned by
CWC ("CWC-Owned Shares") immediately prior to the Effective Time shall, by
virtue of the Merger, cease to be outstanding and shall be canceled and retired
without payment of any consideration therefor; PROVIDED, HOWEVER, that
notwithstanding the foregoing, if CWC waives its rights with respect to the
shares of Merger Sub Common Stock as provided in Section 2.1, in consideration
of such waiver such CWC-Owned Shares shall continue to be outstanding to the
maximum extent permitted by law and shall represent, on a share-for-share basis,
the shares of common stock of the Surviving Corporation.
 
    (c) Notwithstanding anything contained in this Section 2.2 to the contrary,
each NYNEX CableComms US Share of Common Stock issued and held in the treasury
of NYNEX CableComms US or held by any subsidiary of NYNEX CableComms US
immediately prior to the Effective Time shall, by virtue of the Merger, cease to
be outstanding and shall be canceled and retired without payment of any
consideration therefor.
 
    (d) Notwithstanding anything in this Section 2.2 to the contrary, NYNEX
CableComms US Shares of Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by shareholders who
have not voted such NYNEX CableComms US Shares of Common Stock in favor of the
Merger and who shall have properly exercised their rights of appraisal (if any)
for such NYNEX CableComms US Shares of Common Stock in the manner provided by
the DGCL (the "Dissenting Shares") shall not be converted into or be
exchangeable for the right to receive the Merger Consideration, unless and until
such holder shall have failed to perfect or shall have effectively withdrawn or
lost his right to appraisal and payment (if any), as the case may be. If such
holder shall have so failed to perfect or shall have effectively withdrawn or
lost such right (if any), his shares shall thereupon be deemed to have been
converted into and to have become exchangeable for, at the Effective Time, the
right to receive the Merger Consideration. NYNEX CableComms US shall give CWC
prompt notice of any Dissenting Shares (and shall also give CWC prompt notice of
any withdrawals of such demands for appraisal rights) and CWC shall have the
right to direct all negotiations and proceedings with respect to any such
demands. Neither NYNEX CableComms US nor the Surviving Corporation shall, except
with the prior written consent of CWC, voluntarily make any payment with respect
to, or settle or offer to settle, any such demand for appraisal rights.
 
    (e) Pursuant to Section 2.1, CWC hereby agrees to waive its rights with
respect to its shares of Merger Sub Common Stock in consideration for the
CWC-Owned Shares continuing to be outstanding to the maximum extent permitted by
law and representing, on a share-for-share basis, the shares of common stock of
the Surviving Corporation.

    SECTION 2.3.  ELECTIONS BY HOLDERS OF SHARES.
 
    (a) Each person who, at the Effective Time, is a record holder of Shares
shall have the right to submit an Election Form (as defined in Section 2.3(c))
specifying the number of Shares that such person desires to have converted into
the right to receive CWC ADSs pursuant to an ADS Election.
 
    (b) As of the Effective Time, CWC shall (i) deposit (or cause to be
deposited) with a bank or trust company to be designated by CWC and reasonably
acceptable to NYNEX CableComms US (the "Exchange Agent" ), for the benefit of
the holders of Shares, for exchange in accordance with this Article II,
certificates representing the CWC Ordinary Shares ("CWC Certificates") for
exchange in accordance with this Article II and (ii) deposit (or cause to be
deposited) with Citibank, N.A., as custodian and depositary (the "Depositary"),
for the benefit of the holders of Shares, CWC Certificates and shall cause the
Depositary to issue and deposit with the Exchange Agent, American Depositary
Receipts evidencing CWC ADSs ("CWC ADRs") for exchange in accordance with this
Article II. CWC Ordinary Shares or CWC ADSs, as the case may be, into which
Shares shall be converted pursuant to the Merger, as well as CWC Ordinary Shares
represented by such CWC ADSs, shall be deemed to have been issued at the
Effective Time.
 
    (c) As soon as reasonably practicable after the Effective Time, the Exchange
Agent shall mail to each holder of record of Shares immediately prior to the
Effective Time (i) a letter of transmittal (the "Letter of Transmittal") (which
shall specify that delivery shall be effected, and risk of loss and title to
Unit Certificates or Share Certificates, as the case may be, shall pass, only
upon delivery of such Unit Certificates or Share Certificates, as the case may
be, to the Exchange Agent and shall be in such form and have such other
provisions as CWC shall specify), (ii) instructions for use in effecting the
surrender of Unit Certificates or Share Certificates, as the case may be, in
exchange for the Merger Consideration with respect to the Shares formerly
represented thereby, and (iii) an election form (the "Election Form") providing
for such holders to make the ADS Election. All holders of Shares immediately
prior to the Effective Time that shall not have submitted to the Exchange Agent,
or shall have properly revoked, an effective, properly completed Election Form
shall receive the Stock Consideration.
 
    (d) An ADS Election shall have been validly made only if the Exchange Agent
shall have received an Election Form properly completed and executed (with the
signature or signatures thereof guaranteed to the extent required by the
Election Form) by such holder accompanied by such holder's Unit Certificates or
Share Certificates, as the case may be, or by an appropriate guarantee of
delivery of such Unit Certificates or Share Certificates, as the case may be,
from a member of any registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company in
the United States as set forth in such Election Form. Any holder of Shares who
has made an ADS Election by submitting an Election Form to the Exchange Agent
may, at any time prior to the delivery by the Exchange Agent of the Merger
Consideration to which such holder is entitled, revoke his or her election and
withdraw his or her Unit Certificates or Share Certificates, as the case may be,
deposited with the Exchange Agent by written notice to the Exchange Agent.
 
       (e)(i) Upon surrender of a Unit Certificate or Share Certificate, as the
    case may be, for cancellation to the Exchange Agent, together with the
    Letter of Transmittal duly executed, and such other documents as CWC or the
    Exchange Agent shall reasonably request, the holder of such Unit Certificate
    or Share Certificate, as the case may be, shall be entitled to receive as
    soon as practicable after the Effective Time in exchange therefor:
 
       (A) with respect to Shares represented by such Unit Certificate or Share
    Certificate, as the case may be, with respect to which an ADS Election has
    been effectively made and not revoked pursuant to Section 2.3(c), (d) and
    (e), CWC ADRs evidencing that number of whole CWC ADSs, if any, which such
    holder has the right to receive pursuant to this Article II and in lieu of
    fractional CWC ADSs, a CWC Certificate representing that number of whole CWC
    Ordinary Shares, if any, represented by such fractional CWC ADS and a
    certified or bank cashier's check in the amount equal to cash in lieu
 
                                       4
<PAGE>
    of any fractional CWC Ordinary Shares represented by such fractional CWC ADS
    payable pursuant to Section 2.4(c) (in each case less the amount of any
    required withholding taxes); or
 
        (B) with respect to Shares represented by such Unit Certificate or Share
    Certificate, as the case may be, with respect to which an ADS Election has
    not been effectively made or has been revoked pursuant to Section 2.3(c),
    (d) and (e), a CWC Certificate representing that number of whole CWC
    Ordinary Shares, if any, which such holder has the right to receive pursuant
    to this Article II and a certified or bank cashier's check in the amount
    equal to the cash in lieu of fractional shares of CWC Ordinary Shares
    payable pursuant to Section 2.4(c) (less the amount of any required
    withholding taxes); and
 
        (ii) If Compulsory Acquisition of NYNEX CableComms UK Ordinary Shares
    shall have been effected, but the holder has not theretofore received the
    consideration that such holder is entitled to receive pursuant to the
    Compulsory Acquisition, upon surrender of such holder's Unit Certificate
    such holder shall receive such consideration that such holder is entitled to
    pursuant to the Compulsory Acquisition, provided that such holder has
    complied with the applicable requirements of the Companies Act with respect
    to the Compulsory Acquisition.
 
    The Unit Certificate or Share Certificate, as the case may be, so
surrendered shall forthwith be canceled. Until surrendered as contemplated by
this Section 2.3(e), each Unit Certificate or Share Certificate, as the case may
be, shall be deemed at any time after the Effective Time to represent only the
right to receive the Merger Consideration with respect to the Shares formerly
represented thereby and with respect to a Unit Certificate only, if a Compulsory
Acquisition shall have been effected, any consideration payable with respect to
the NYNEX CableComms UK Ordinary Shares formerly represented thereby subject to
the Compulsory Acquisition.
 
    (f) CWC shall have the right to make reasonable rules, not inconsistent with
the terms of this Merger Agreement, governing the validity of the Election Forms
and the issuance and delivery of CWC Certificates or CWC ADRs, as the case may
be, into which Shares are converted in the Merger.
 
    (g) The parties hereto may in their discretion, but shall not be obligated
to, establish further procedures by which holders of American Depositary Shares
representing NYNEX CableComms Units ("NYNEX CableComms ADSs"), in part
representing Shares, may make an ADS Election and/or receive the Merger
Consideration with respect to the Shares represented by their NYNEX CableComms
ADSs.
 
    SECTION 2.4.  DIVIDENDS, FRACTIONAL SHARES, ETC.
 
    (a) Notwithstanding any other provisions of this Merger Agreement, no
dividends or other distributions declared after the Effective Time on CWC
Ordinary Shares or CWC ADSs, as the case may be, shall be paid with respect to
any Shares which, prior to the Effective Time, were represented by a Unit
Certificate or Share Certificate, as the case may be, until such Unit
Certificate or Share Certificate, as the case may be, is surrendered for
exchange as provided herein. Subject to the effect of applicable laws, following
surrender of any such Unit Certificate or Share Certificate, as the case may be,
there shall be paid to the holder of the CWC Certificates or CWC ADRs, as the
case may be, issued in exchange 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 payable with respect to such whole CWC
Ordinary Shares or CWC ADSs, as the case may be, and not paid, less the amount
of any withholding taxes which may be required thereon, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole CWC Ordinary Shares
or CWC ADSs, as the case may be, less the amount of any withholding taxes which
may be required thereon.
 
    (b) At or after the Effective Time, there shall be no transfers on the stock
transfer books of NYNEX CableComms US of the Unit Certificates or Share
Certificates, as the case may be, which were outstanding
 
                                       5
<PAGE>
immediately prior to the Effective Time. If, after the Effective Time, Unit
Certificates or Share Certificates, as the case may be, formerly representing
any such Shares are presented to the Surviving Corporation, they shall be
canceled and exchanged for CWC Certificates or CWC ADRs (if any), as the case
may be, deliverable in respect thereof pursuant to this Merger Agreement in
accordance with the procedures set forth in this Article II.
 
        (c)  (i) No fractional CWC Ordinary Shares shall be issued pursuant to
    the Merger. In lieu of the issuance of any fractional CWC Ordinary Shares
    pursuant to the Merger, fractional CWC Ordinary Shares shall be aggregated
    and sold in the market and the net proceeds of sale distributed PRO RATA to
    such holders (less the amount of any withholding taxes); PROVIDED, HOWEVER,
    that CWC shall have no liability to any person for any loss or alleged loss
    arising from the price, timing or manner of any such sale.
 
            (ii) No fractional CWC ADSs shall be issued pursuant to the Merger.
    In lieu of the issuance of any fractional CWC ADSs pursuant to the Merger,
    each holder of Shares who would otherwise be entitled to receive a
    fractional CWC ADS will be issued a CWC Certificate representing such whole
    number of CWC Ordinary Shares represented by such fractional CWC ADS and
    cash in lieu of any fractional CWC Ordinary Shares represented by such
    fractional CWC ADS shall be paid as described in Section 2.4(c)(i).
 
    (d) Any CWC Ordinary Shares, CWC ADSs or funds (including the proceeds of
any sales of CWC Ordinary Shares or CWC ADSs to pay cash in lieu of fractional
CWC Ordinary Shares or CWC ADSs), as the case may be, that remain unclaimed by
the former holders of Shares of NYNEX CableComms US six months after the
Effective Time shall be delivered to CWC. Any former holder of Shares of NYNEX
CableComms US who has not theretofore complied with this Article II shall
thereafter look only to CWC for payment of the consideration payable on account
of the Merger, cash in lieu of fractional CWC Ordinary Shares or CWC ADSs and
unpaid dividends and distributions on the CWC Ordinary Shares or CWC ADSs, as
the case may be, deliverable in respect of each CWC Ordinary Share or CWC ADS,
as the case may be, that such holder of Shares holds as determined pursuant to
this Merger Agreement, in each case without any interest thereon.
 
    (e) None of NYNEX CableComms US, CWC, the Exchange Agent, nor any other
person shall be liable to any former holder of Shares for any amount properly
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws.
 
    (f) In the event that any Unit Certificate or Share Certificate, as the case
may be, shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Unit Certificate or Share
Certificate, as the case may be, to be lost, stolen or destroyed and, if
required by CWC, the posting by such person of a bond in such reasonable amount
as CWC may direct as indemnity against any claim that may be made against it
with respect to such Unit Certificate or Share Certificate as the case may be,
the Exchange Agent will issue in exchange for such lost, stolen or destroyed
Unit Certificate or Share Certificate, as the case may be, the applicable Merger
Consideration, cash in lieu of fractional CWC Ordinary Shares, and unpaid
dividends and distributions on CWC Ordinary Shares or CWC ADSs, as the case may
be, as provided in this Section 2.4, deliverable in respect thereof pursuant to
this Merger Agreement.

make the statements therein not misleading; PROVIDED, HOWEVER, that no

otherwise modified for a period of six years after the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who at

of actions or omissions occurring at or prior to the Effective Time (including,
without limitation, the transactions contemplated by this Merger Agreement),
unless such modification is required by law. CWC shall guarantee the obligations
of the Surviving Corporation under this Section 3.6(a).
 
    (b) CWC shall cause the Surviving Corporation to use its reasonable best
efforts to maintain in effect for six years from the Effective Time, if
available, the coverage provided by the current directors' and officers'
liability insurance policies maintained by NYNEX Corporation (provided that the
Surviving Corporation may substitute therefor policies of at least the same
coverage containing terms and conditions which are not materially less
favorable) with respect to matters occurring prior to the Effective Time.
 
    (c) This Section 3.6 shall survive the Effective Time, and is intended to be
for the benefit of, and shall be enforceable by, the directors and officers of
NYNEX CableComms US and shall be binding on CWC and Merger Sub and the Surviving
Corporation and their respective successors and assigns.

NYNEX CableComms Group Inc.
The Tolworth Tower
Ewell Road
Surbiton, Surrey KT6 7ED
United Kingdom
 
Gentlemen:
 
    The undersigned, a holder of Units or American Depositary Shares
representing in part shares of Common Stock, par value $.01 per share ("Common
Stock"), of NYNEX CableComms Group Inc., a Delaware corporation ("NYNEX
CableComms US"), is entitled to receive in connection with the merger (the
"Merger") of NYNEX CableComms US with Cable & Wireless Communications Delaware
Inc., a Delaware corporation, Ordinary Shares of 50p each ("CWC Ordinary
Shares") or American Depositary Shares ("CWC ADSs") representing CWC Ordinary
Shares of Cable & Wireless Communications plc, a public limited company
incorporated under the laws of England and Wales ("CWC"). The undersigned
acknowledges that the undersigned may be deemed an "affiliate" of NYNEX
CableComms US within the meaning of Rule 145 ("Rule 145") promulgated under the
Securities Act of 1933, as amended (the "Act"), although nothing contained
herein should be construed as an admission of such fact.
 
    If in fact the undersigned were an affiliate under the Act, the
undersigned's ability to sell, assign or transfer the CWC Ordinary Shares or CWC
ADSs received by the undersigned pursuant to the Merger may be restricted unless
such transaction is registered under the Act or an exemption from such
registration is available. The undersigned understands that such exemptions are
limited and the undersigned has obtained advice of counsel as to the nature and
conditions of such exemptions, including information with respect to the
applicability to the sale of such securities of Rules 144 and 145(d) promulgated
under the Act.
 
    The undersigned hereby represents to and covenants with CWC that the
undersigned will not sell, assign or transfer any of the CWC Ordinary Shares or
CWC ADSs received by the undersigned pursuant to the Merger except (i) pursuant
to an effective registration statement under the Act, (ii) in conformity with
the volume and other limitations of Rule 144 and Rule 145 or (iii) in a
transaction which, in the opinion of independent counsel reasonably satisfactory
to CWC or as described in a "no-action" or interpretive letter from the Staff of
the Securities and Exchange Commission (the "SEC"), is not required to be
registered under the Act.
 
    In the event of a sale or other disposition by the undersigned of CWC
Ordinary Shares or CWC ADSs received by the undersigned in the Merger pursuant
to Rule 145, the undersigned will supply CWC with evidence reasonably
satisfactory to CWC of compliance with such Rule. The undersigned understands
that CWC may instruct its transfer agent or the Depositary for the CWC ADSs (the
"Depositary") to withhold the transfer of such CWC Ordinary Shares or CWC ADSs,
respectively, sold or disposed of by the undersigned, subject to receipt of such
evidence of compliance. Following such receipt, the transfer agent or Depositary
shall effectuate the transfer of the CWC Ordinary Shares or CWC ADSs sold or
disposed of by the undersigned.
 
    The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing CWC Ordinary Shares or American Depositary
Receipts ("CWC ADRs") evidencing CWC ADSs received by the undersigned in the
Merger or held by a transferee thereof, which legends will be removed by
delivery of substitute certificates or CWC ADRs upon receipt of an opinion in
form and substance reasonably satisfactory to CWC from independent counsel
reasonably satisfactory to CWC to the effect that such legends are no longer
required for purposes of the Act.
 
    The undersigned acknowledges that (i) the undersigned has carefully read
this letter and understands the requirements hereof and the limitations imposed
upon the distribution, sale, transfer or other disposition of securities and
(ii) the receipt by CWC of this letter is an inducement to CWC's obligations to
consummate the Merger.
 
                                          Very truly yours,
     ---------------------------------------------------------------------------
