    Your board of directors has unanimously approved a merger with Vodafone
Group Public Limited Company. The combined company will be the world's largest
wireless telecommunications company.
 
    This merger is an important step for Vodafone and AirTouch in achieving our
common goal of creating the world's premier mobile communications company. Our
companies already share a vision of wireless telecommunications as a major
platform for voice and data communications in the next century; we believe that
this transaction creates the ideal union of people and assets to realize that
vision.
 
    In the merger, Vodafone AirTouch will issue 0.5 of a Vodafone AirTouch ADS
and pay $9.00 in cash to holders of AirTouch common stock for each share held
and will issue 0.403 of a Vodafone AirTouch ADS and pay $7.25 in cash to holders
of AirTouch Class B preferred stock for each share held. Each Vodafone AirTouch
ADS will represent 10 ordinary shares of Vodafone AirTouch and will be listed on
the New York Stock Exchange under the symbol "VOD." After the merger, AirTouch
stockholders are expected to hold slightly less than 50% of the equity of
Vodafone AirTouch.
 
    Holders of AirTouch common stock and AirTouch Class B preferred stock voting
together must approve the merger. The directors of AirTouch unanimously
recommend that the stockholders of AirTouch vote "FOR" the merger.
 
    This document provides you with detailed information about the proposed
merger. You are encouraged to read this entire document before you decide how
you wish to vote. YOU SHOULD ALSO CAREFULLY CONSIDER THE RISK FACTORS RELATING
TO THE MERGER DESCRIBED BEGINNING ON PAGE 20 OF THIS DOCUMENT. In addition, this
document incorporates important business and financial information that is not
included in this document. You may obtain this information without charge by
request from the appropriate company at the address listed on page 19. TO OBTAIN
TIMELY DELIVERY OF THE INFORMATION, PLEASE REQUEST DOCUMENTS BY MAY 14, 1999.
 
    YOUR VOTE IS VERY IMPORTANT. To vote your shares, you may use the enclosed
proxy card, vote by telephone by calling (800) 650-3514 or attend the special
stockholder meeting. If your shares are held in "street name", i.e., in the name
of a broker, bank or other record holder, you must either direct the record
holder as to how to vote your shares or obtain a proxy from the record holder to
vote at the special meeting. The special meeting will be held on May 28, 1999,
at 8:00 a.m., Pacific time, at the Hiller Aviation Museum, 601 Skyway Road, San
Carlos, CA 94070. If you fail to vote, the effect will be a vote against the
merger.
 
    I urge you to vote "FOR" the merger.
 
                                          Very truly yours,

will:
 
    1.  Consider and vote on a proposal to approve and adopt the Agreement and
       Plan of Merger, dated as of January 15, 1999, among Vodafone Group Public
       Limited Company, AirTouch and Apollo Merger Sub, Inc., a wholly owned
       subsidiary of Vodafone, providing for the merger of Apollo Merger Sub,
       Inc. with and into AirTouch. After the merger, AirTouch will be a

       meeting or any adjournment or postponement of the special meeting.

common stock, except with respect to cash received in the merger.

with the proposed transactions.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q.  WHY ARE VODAFONE AND AIRTOUCH PROPOSING TO MERGE?
 
A. Vodafone and AirTouch believe that the merger of two of the world's leading
    mobile telecommunications companies will create a more competitive, global
    wireless telecommunications company than either Vodafone or AirTouch would
    be on its own and will generate significant opportunities to deliver greater
    value to shareholders.
 
Q.  WHAT WILL AIRTOUCH STOCKHOLDERS RECEIVE IN THE MERGER?
 
A. Holders of AirTouch common stock will receive 0.5 of a Vodafone AirTouch ADS
    and $9.00 in cash for each share of AirTouch common stock held. Holders of
    AirTouch Class B preferred stock will receive 0.403 of a Vodafone AirTouch
    ADS and $7.25 in cash for each share of AirTouch Class B preferred stock
    held.
 
Q.  WHAT IS A VODAFONE AIRTOUCH ADS?
 
A. A Vodafone AirTouch ADS is an American depositary share which represents 10
    Vodafone AirTouch ordinary shares and which has been created to allow U.S.
    shareholders to more easily hold and trade interests in Vodafone AirTouch on
    U.S. markets after the merger. The Bank of New York will be the depositary
    which will issue the Vodafone AirTouch ADSs and own the Vodafone AirTouch
    ordinary shares represented by the ADSs. For a discussion of the differences
    between owning Vodafone AirTouch ADSs and Vodafone AirTouch ordinary shares,
    see "DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY SHARES--General."
 
Q.  IS THE MERGER TAXABLE?
 
A. The merger will be tax free to U.S. holders of AirTouch common stock,
    including holders of preferred stock who convert their shares prior to the
    merger, except with respect to cash received in the merger.
 
Q.  WHEN IS THE MERGER EXPECTED TO BE COMPLETED?
 
A. Vodafone and AirTouch expect to complete the merger in June or July of 1999.
    Because the merger is subject to governmental approvals, the companies
    cannot predict the exact timing.
 
Q.  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?
 
A. No. After the companies complete the merger, Vodafone AirTouch will send
    instructions to AirTouch stockholders whose shares were converted in the
    merger. These instructions will explain how to exchange your AirTouch stock
    certificates for Vodafone AirTouch ADSs and cash.
 
Q.  HOW DO I VOTE?
 
A. After you have carefully read this proxy statement/prospectus, just mail your
    signed proxy card in the enclosed postage-paid envelope to The Bank of New
    York as soon as possible so that your shares may be represented and voted at
    the AirTouch special meeting. You may also vote by telephone by calling
    (800) 650-3514, or you may vote in person at the AirTouch special meeting.
    If your shares are held in "street name", i.e., in the name of a broker,
    bank or other record holder, you must either direct the record holder as to
    how to vote your shares or obtain a proxy from the record holder to vote at
    the special meeting.
 
Q.  MAY I CHANGE MY VOTE?
 
A. Yes. You may withdraw your proxy or change your vote by delivering a
    later-dated, signed written notice of revocation or proxy card to The Bank
    of New York before the AirTouch special meeting or by voting in person at
    the AirTouch special meeting. You may also withdraw your proxy or change
    your vote by telephone as described in this proxy statement/prospectus.
 
Q.  WHOM CAN I CALL WITH QUESTIONS?
 
A. If you have more questions about the merger, you should contact:

    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROXY
STATEMENT/PROSPECTUS. IT DOES NOT CONTAIN ALL OF THE INFORMATION THAT IS
IMPORTANT TO YOU. YOU SHOULD READ CAREFULLY THE ENTIRE PROXY STATEMENT/
PROSPECTUS AND THE ADDITIONAL DOCUMENTS REFERRED TO IN THIS PROXY
STATEMENT/PROSPECTUS TO FULLY UNDERSTAND THE MERGER.
 
THE COMPANIES
 
VODAFONE GROUP PUBLIC LIMITED COMPANY
The Courtyard
2-4 London Road
Newbury, Berkshire RG14 1JX
England
(011 44) 1635 33251
 
    Vodafone is a leading international provider of mobile telecommunications
services. Vodafone owns interests in mobile operations in the United Kingdom and
12 other countries, as well as an interest in the Globalstar satellite system.
As of March 31, 1999, Vodafone had over 10.4 million customers based on its
ownership share of its telecommunications ventures. Vodafone was incorporated in
England in 1984.
 
AIRTOUCH COMMUNICATIONS, INC.
One California Street
San Francisco, CA 94111
(415) 658-2000
 
    AirTouch is a leading international mobile telecommunications company with a
significant presence in the United States, Europe and Asia. As of March 31,
1999, AirTouch had over 18.8 million customers based on its ownership share of
the cellular, paging and personal communications service ventures in which it
has an interest.
 
THE MERGER (SEE PAGE 29)
 
    In the merger, AirTouch will become a subsidiary of Vodafone. In addition,
Vodafone AirTouch will issue ordinary shares with an approximate value of $52.4
billion, based on the closing price of a Vodafone ADS on April 20, 1999, and
will pay approximately $5.5 billion in cash to AirTouch stockholders. Upon
completion of the merger, Vodafone will change its name to "Vodafone AirTouch
Public Limited Company."
RECOMMENDATION OF THE AIRTOUCH BOARD (SEE PAGE 33)
 
    The AirTouch board has unanimously determined that the merger is in the best
interests of AirTouch and its stockholders and approved the merger, the merger
agreement and the agreement providing for the internal reorganization and
declared their advisability. Accordingly, the AirTouch board recommends that
AirTouch stockholders vote "FOR" approval and adoption of the merger agreement
and "FOR" approval and adoption of the agreement providing for the internal
reorganization.
 
OPINION OF FINANCIAL ADVISOR (SEE PAGE 37)
 
    Morgan Stanley & Co. Incorporated delivered a written opinion to the
AirTouch board that, as of the date of the opinion, the merger consideration was
fair to AirTouch stockholders from a financial point of view. This opinion is
not a recommendation to any AirTouch stockholder as to how to vote. We have
attached this opinion to the proxy statement/prospectus as Appendix B. You
should read it carefully.
 
SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION (SEE PAGE 55)
 
    Vodafone expects to pay approximately $5.5 billion in cash to holders of
AirTouch common stock in the merger. This payment, as well as expenses related
to the merger, will be financed by a new $10.5 billion credit facility which
Vodafone and AirTouch entered into on April 16, 1999 and from generally
available funds of Vodafone and AirTouch.
 
DIRECTORS AND MANAGEMENT OF VODAFONE AIRTOUCH FOLLOWING THE MERGER (SEE PAGE
152)
 
    At the time the merger becomes effective, the board of directors of Vodafone
AirTouch will consist of 14 directors, seven of whom Vodafone
 
                                       1
<PAGE>
will designate and seven of whom AirTouch will designate. The current chief
executive of Vodafone, Chris Gent, will be the chief executive of Vodafone
AirTouch and the current chairman and chief executive officer of AirTouch, Sam
Ginn, will be the non-executive chairman of Vodafone AirTouch.
 
INTERESTS OF MEMBERS OF THE AIRTOUCH BOARD AND MANAGEMENT (SEE PAGE 50)
 
    When considering the AirTouch board's recommendation that you vote in favor
of approval and adoption of the merger agreement, you should be aware that the
directors and officers of AirTouch may have interests in the merger that are
different from, or in addition to, yours as an AirTouch stockholder.
 
RISK FACTORS (SEE PAGE 20)
 
    In determining whether to vote to approve and adopt the merger agreement,
you should consider carefully the risk factors described in this document,
including the risks that:
 
    - expected benefits from the Vodafone/ AirTouch combination may not be
      realized,
 
    - the European Commission or the FCC may delay the merger or impose
      conditions which reduce the anticipated benefits of the merger, either of
      which could adversely affect the stock price of Vodafone, AirTouch or
      Vodafone AirTouch,
 
    - the value of Vodafone AirTouch ADSs that AirTouch stockholders will
      receive in the merger will fluctuate, and
 
    - AirTouch will likely be removed from the S&P 500 index, which may
      adversely affect the market price of a Vodafone AirTouch ADS.
 
CONDITIONS TO THE MERGER (SEE PAGE 81)
 
    Vodafone and AirTouch will not complete the merger unless a number of
conditions are satisfied or waived by them. These include:
 
    - approval by Vodafone and AirTouch shareholders,
    - clearance under applicable European Union antitrust laws and approval of
      the Federal Communications Commission and regulatory authorities of
      various states and European countries, in each case without conditions
      that would have a material adverse effect on Vodafone and AirTouch on a
      combined basis,
 
    - opinions of tax counsel to the effect that the merger will be tax free to
      U.S. holders of AirTouch common stock for U.S. federal income tax
      purposes, except with respect to cash received, and
 
    - completion of the AirTouch internal reorganization.
 
TERMINATION OF THE MERGER AGREEMENT
(SEE PAGE 84)
 
    Either Vodafone or AirTouch may terminate the merger agreement if it is not
in material breach of the merger agreement and:
 
    - Vodafone and AirTouch do not complete the merger by December 31, 1999, or
      if an additional three month period is necessary to obtain regulatory
      approval of the merger, by March 31, 2000; or
 
    - the shareholders of Vodafone or AirTouch do not approve the merger at the
      applicable shareholders' meeting; or
 
    - a governmental authority permanently restrains, enjoins or otherwise
      prohibits the merger.
 
    Additionally, either Vodafone or AirTouch may terminate the merger agreement
if:
 
    - the board of directors of the other company withdraws its recommendation
      of the merger to its shareholders; or
 
    - the other company recommends another acquisition transaction proposed by a
      third party; or
 
    - the other company breaches any of its representations, warranties or
      agreements under the merger agreement, and this breach results in the
      failure of a condition to the merger to be met which cannot be
 
                                       2
<PAGE>
      or is not cured prior to December 31, 1999.
 
TERMINATION PAYMENTS (SEE PAGE 85)
 
    AirTouch will be required to pay Vodafone a termination payment of $1
billion and Vodafone will be required to pay AirTouch a termination payment of
$225 million if the merger agreement is terminated because:
 
    - the board of directors of the non-terminating party withdraws its
      recommendation of the merger to its shareholders; or
 
    - the board of directors of the non-terminating party recommends another
      acquisition transaction proposed by a third party; or
 
    - the non-terminating party intentionally breaches a material
      representation, warranty or agreement made in the merger agreement which
      cannot be or is not cured prior to December 31, 1999.
 
    If, however, the merger agreement is terminated because AirTouch's
stockholders fail to adopt the merger agreement and, at that time, there is an
offer from a third party to acquire AirTouch, AirTouch will be required to pay
Vodafone a termination payment of $225 million and if, within 12 months of
termination, AirTouch enters into an agreement in which a third party agrees to
acquire AirTouch or a third party completes an acquisition of AirTouch, to pay
an additional $775 million. Vodafone will be required to pay AirTouch a
termination payment of $225 million if the merger agreement is terminated
because Vodafone's shareholders fail to approve the merger.
 
APPRAISAL RIGHTS (SEE PAGE 87)
 
    Under Delaware law, holders of AirTouch common stock have the right to
demand and to receive, instead of what Vodafone is offering in the merger, an
amount that the Delaware Court of Chancery decides is the fair value of such
shares of AirTouch common stock. This amount may be more or less than the value
of what these holders would otherwise receive in the merger.
 
    Holders of AirTouch common stock wishing to exercise appraisal rights must
not vote in favor of adoption of the merger agreement and must take the steps
described in the section entitled "APPRAISAL RIGHTS" and set forth in full in
Appendix F.
 
    In addition, holders of AirTouch Class D preferred stock and AirTouch Class
E preferred stock have the right to demand appraisal rights in connection with
the merger and the internal reorganization. Any holder of AirTouch Class D
preferred stock or AirTouch Class E preferred stock wishing to exercise
appraisal rights must take the steps described in the section entitled
"APPRAISAL RIGHTS" and set forth in full in Appendix F.
 
LISTING OF VODAFONE AIRTOUCH ADSS AND ORDINARY SHARES (SEE PAGE 92)
 
    The Vodafone AirTouch ADSs you receive in the merger will be listed on the
NYSE and the Vodafone AirTouch ordinary shares underlying those ADSs will be
admitted to the Official List of the London Stock Exchange.
 
ACCOUNTING TREATMENT (SEE PAGE 55)
 
    Vodafone will account for the merger as an acquisition under generally
accepted accounting principles in the United Kingdom and as a purchase for
purposes of generally accepted accounting principles in the United States.
 
U.S. FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 65)
 
    The merger will be tax free to U.S. holders of AirTouch common stock,
including holders of AirTouch preferred stock who convert their shares prior to
the merger, except with respect to cash received in the merger. The internal
reorganization, however, may be taxable to holders of AirTouch Class C preferred
stock who do not convert their shares into shares of AirTouch common stock prior
to the internal reorganization.
 
                                       3
<PAGE>
RECORD DATE FOR VOTING; VOTE REQUIRED OF AIRTOUCH STOCKHOLDERS (SEE PAGE 22)
 
    You can vote at the special meeting of AirTouch stockholders if you owned
AirTouch common stock or AirTouch Class B preferred stock on April 13, 1999.
 
    To approve the merger agreement and the agreement providing for the internal
reorganization, holders of a majority of the AirTouch common stock and the
AirTouch Class B preferred stock voting together as one class must vote in favor
of doing so. Each share of AirTouch common stock outstanding on the record date
is entitled to one vote and each share of AirTouch Class B preferred stock is
entitled to four-fifths of one vote. There are no other classes of voting
securities of AirTouch presently outstanding. As of the record date, directors
and executive officers of AirTouch and their affiliates owned approximately
0.10% and 0.21% of the outstanding shares of AirTouch common stock and AirTouch
Class B preferred stock, respectively.
 
VOTE REQUIRED OF VODAFONE SHAREHOLDERS (SEE PAGE 25)
 
    At the Vodafone shareholders' meeting Vodafone shareholders will vote:
 
    - to approve the merger and to elect new directors to the board of Vodafone
      AirTouch, each of which will require the approval of a majority of the
      votes cast at the Vodafone shareholders' meeting, and
 
    - to change Vodafone's name to "Vodafone AirTouch Public Limited Company,"
      redenominate Vodafone's ordinary share capital from pounds sterling into
      U.S. dollars, increase Vodafone's authorized capital, authorize the
      directors of Vodafone to issue shares, and authorize amendments to
      Vodafone's memorandum and articles of association, each of which will
      require the approval of at least 75% of the votes cast at the Vodafone
      shareholders' meeting.
 
Vodafone shareholders must approve all of these matters, except the
redenomination, in order for the merger to be completed.
 
COMPARISON OF RIGHTS OF HOLDERS OF VODAFONE AIRTOUCH ORDINARY SHARES WITH
HOLDERS OF AIRTOUCH COMMON STOCK (SEE PAGE 126)
 
    As a result of the merger, holders of AirTouch common stock will receive
Vodafone AirTouch ADSs. Each Vodafone AirTouch ADS will represent ten ordinary
shares of Vodafone AirTouch. There are numerous differences between the rights
of a stockholder in AirTouch, a Delaware corporation, and the rights of a
shareholder in Vodafone AirTouch, an English company. For example,
 
    - except in limited circumstances, holders of Vodafone AirTouch ordinary
      shares will not be entitled to appraisal rights in mergers or any other
      types of transactions;
 
    - only holders representing 5% or more of the voting power of Vodafone
      AirTouch will be able to make proposals at a shareholders meeting;
 
    - persons acquiring 3% or more of the voting power of Vodafone AirTouch will
      generally be required to make public disclosures and notifications with
      respect to their ownership;
 
    - amendments to the memorandum and articles of association of Vodafone
      AirTouch will require the approval of at least 75% of the votes cast at a
      shareholders meeting;
 
    - Vodafone AirTouch generally will not be permitted the same freedom as
      AirTouch has to adopt defensive measures in the event of a takeover bid;
      and
 
    - although holders of Vodafone AirTouch ordinary shares will be permitted to
      initiate lawsuits on behalf of the company in limited circumstances,
      holders will not be able to initiate class action lawsuits against
      Vodafone AirTouch.
 
    You should also be aware that it may be difficult to effect service of
process to begin a lawsuit in a U.S. court against directors and officers of
Vodafone AirTouch who are not residents of the U.S.

COMPARISON OF RIGHTS OF HOLDERS OF VODAFONE AIRTOUCH ADSS WITH HOLDERS OF
VODAFONE AIRTOUCH ORDINARY SHARES (SEE PAGE 128)
 
    Your rights as a holder of Vodafone AirTouch ADSs will in some cases be
different from the rights of a holder of Vodafone AirTouch ordinary shares. For
example, if proposed amendments to Vodafone's articles of association are
adopted at the Vodafone shareholders' meeting, you, as an individual holder of
ADSs, will be entitled to attend, speak and vote at Vodafone AirTouch general
shareholder meetings if you hold your Vodafone AirTouch ADSs directly. If,
however, you hold Vodafone AirTouch ADSs through a brokerage account or
otherwise in "street name," you will not be entitled to attend or speak at a
meeting, but you will be able to vote your ADSs by instructing the depositary.
See page 126 for a more complete description of your voting rights after the
merger.

COMPARATIVE MARKET PRICE DATA
 
    The following table presents per share closing market prices as reported on
the NYSE for Vodafone ADSs and shares of AirTouch common stock and the closing
mid-market quotation for Vodafone ordinary shares as quoted in the Official List
of the London Stock Exchange on January 15, 1999, prior to any public
announcement of the signing of the merger agreement, and on April 20, 1999, the
latest practicable date prior to the printing of this document. The table also
presents implied equivalent per share values for shares of AirTouch common stock
by multiplying the price per Vodafone ADS by 0.5 and adding $9.00.
 
    AirTouch stockholders are urged to obtain current market quotations for the
Vodafone ADSs, Vodafone ordinary shares and AirTouch common stock before making
a decision with respect to the merger.

PROPORTIONATE DATA OF VODAFONE
 
    The following table is presented on a proportionate basis. Proportionate
presentation is not required by U.K. GAAP and is not intended to replace the
consolidated financial statements prepared in accordance with U.K. GAAP.
However, since significant entities in which Vodafone has an interest are not
consolidated, proportionate information is provided as supplemental data to
facilitate a more detailed understanding and assessment of consolidated
financial statements prepared in accordance with U.K. GAAP.
 
    U.K. GAAP requires consolidation of entities controlled by Vodafone and the
equity method of accounting for entities in which Vodafone has significant
influence but not a controlling interest. Proportionate presentation is a pro
rata consolidation, which reflects Vodafone's share of turnover and expenses in
both its consolidated and unconsolidated entities. Proportionate results are
calculated by multiplying Vodafone's ownership interest in each entity by each
entity's results.
 
    Proportionate information includes results from Vodafone's equity accounted
investments and investments held at cost. Vodafone does not have control over
the turnover, expenses or cash flows of these investments and is only entitled
to cash from dividends received from these entities. Vodafone does not own the
underlying assets of these investments.
 
    Proportionate EBITDA before investment disposals in the table below
represents operating profit before exceptional reorganization costs plus
depreciation and amortization of subsidiary undertakings, associated
undertakings and investments, proportionate to equity stakes. Proportionate
EBITDA represents Vodafone's ownership interests in the respective entities'
EBITDA. As such, proportionate EBITDA does not represent EBITDA available to
Vodafone.

PROPORTIONATE DATA OF AIRTOUCH
 
    The following table is presented on a proportionate basis. Proportionate
presentation is not permitted by U.S. GAAP and is not intended to replace the
consolidated operating results prepared and presented in accordance with U.S.
GAAP. However, since significant wireless systems in which AirTouch has an
interest are not consolidated, proportionate information is provided as
supplemental data to facilitate a more detailed understanding and assessment of
consolidated operating results prepared and presented in accordance with U.S.
GAAP.
 
    U.S. GAAP requires consolidation of wireless systems controlled by AirTouch
and the equity method of accounting for wireless systems in which AirTouch has
significant influence but not a controlling interest. Proportionate presentation
is a pro rata consolidation, which reflects AirTouch's share of revenues and
expenses in both its consolidated and unconsolidated wireless systems.
Proportionate results are calculated by multiplying AirTouch's ownership
interest in each wireless system by each system's total operating results, and,
accordingly, should not be compared with U.S. GAAP consolidated results of any
company. Net income under either U.S. GAAP or proportionate presentation is the
same.
 
    Proportionately reported amounts include results from AirTouch's equity
investees, which AirTouch does not control. AirTouch does not have control over
the revenues, expenses or cash flows of its equity investees that are reported
in proportionate results and is only entitled to cash from dividends received
from these entities. AirTouch does not own the underlying assets of its equity
investees.
 
    Proportionate operating cash flow in the table below represents operating
income plus depreciation and amortization and is not the same as cash flow from
operating activities in AirTouch's consolidated statements of cash flows.
Proportionate operating cash flow represents AirTouch's ownership interests in
the respective entities' operating cash flows. As such, proportionate operating
cash flow does not represent cash available to AirTouch.

markets, the AirTouch proportionate interest in PrimeCo's results is slightly
less than 50%.

SIGNIFICANT FACTORS AFFECTING OPERATING RESULTS
 
    Financial results reported in accordance with U.K. GAAP or U.S. GAAP include
the impact of unusual or infrequent events and factors which are not expected to
occur regularly in the future. Examples of these events and factors include
gains or losses on the sale of businesses, the costs of completing major
acquisitions, restructuring charges and other business transactions, as well as
other significant factors and trends. To understand the past performance and
future prospects of Vodafone and AirTouch, it may be helpful to review the items
described briefly below. The following discussion should be read in conjunction
with the "Selected Historical Financial Data" included in the previous pages and
with the "Management's Discussion and Analysis of Financial Condition and
Results of Operations" of Vodafone and AirTouch that are contained in the annual
reports and other information that Vodafone and AirTouch have each filed with
the SEC. See "--Where You Can Find More Information."

AIRTOUCH
 
    ACQUISITIONS
 
    In August 1996, AirTouch acquired the approximately 63% of Cellular
Communications' outstanding stock that it did not already own for approximately
$1.6 billion. The consideration consisted of $1.0 billion in AirTouch preferred
stock, $393 million in cash, AirTouch stock options valued at approximately $17
million, and the assumption of $217 million of zero coupon convertible
subordinated notes due 1999.
 
    In January 1997, AirTouch began consolidating the results of operations of
Telecel Communicacoes Pessoias, S.A., its cellular system in Portugal, after
increasing its ownership from 38.9% to 50.9% in December 1996.
 
    In April 1998, AirTouch completed the acquisition of the U.S. wireless
interests of MediaOne Group, Inc. AirTouch issued approximately 59.4 million
shares of common stock having a fair market value of approximately $2.9 billion
on the date of issuance and approximately $1.6 billion of dividend-bearing
preferred stock with a 5.143% coupon, assumed approximately $1.4 billion of debt
associated with the acquired wireless interests, and granted MediaOne
registration rights with respect to the common stock and preferred stock
described above.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    Vodafone and AirTouch are providing the following pro forma consolidated
financial information to give you a better picture of what the results of
operations and financial position of the combined businesses of Vodafone and
AirTouch might have looked like had the merger occurred on an earlier date. This
information is provided for illustrative purposes only and does not show what
the results of operations or financial position of Vodafone AirTouch would have
been if the merger had actually occurred on the dates assumed. This information
also does not indicate what Vodafone AirTouch's future operating results or
consolidated financial position will be.
 
    Please see "VODAFONE AIRTOUCH UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL
INFORMATION" for a more detailed explanation of this analysis.
 
    BASIS OF PREPARATION
 
    The pro forma consolidated financial information has been prepared in
accordance with U.K. GAAP, which differs from U.S. GAAP. In the pro forma
consolidated financial information, AirTouch's financial position and results of
operations have been adjusted to U.K. GAAP and translated into pounds sterling,
as described in the notes to the pro forma consolidated financial information
contained herein. Pro forma effect has been given to the acquisition by AirTouch
on April 6, 1998 of NewVector, which held the U.S. cellular businesses of
MediaOne Group, Inc., and MediaOne's 25% interest in PrimeCo Personal
Communications, L.P., as described in more detail in AirTouch's current report
on Form 8-K/A filed on April 23, 1998 and incorporated by reference into this
document.
 
    Vodafone AirTouch intends to account for the merger using the acquisition
method of accounting under U.K. GAAP and the purchase method under U.S. GAAP.
The pro forma consolidated financial information has been prepared on this
basis.
 
    UNAUDITED PRO FORMA CONSOLIDATED INCOME STATEMENT DATA
 
    The unaudited pro forma consolidated income statement data assumes that the
merger took place on April 1, 1997, the first day of the earliest financial
period presented in the pro forma consolidated financial information.
 
    The unaudited pro forma consolidated income statement data for the year
ended March 31, 1998 combines the historical consolidated income statement of
Vodafone for the year ended March 31, 1998 and the pro forma income statement of
AirTouch for the year ended December 31, 1997, as adjusted to U.K. GAAP, after
giving effect to the pro forma adjustments described in the notes to the
unaudited pro forma consolidated financial information.
 
    The pro forma consolidated income statement data for the six months ended
September 30, 1998 combines the unaudited historical consolidated income
statements of Vodafone and AirTouch for that period, as adjusted to U.K. GAAP,
after giving effect to the pro forma adjustments described in the notes to the
unaudited pro forma consolidated financial information.
 
    UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET DATA
 
    The unaudited pro forma consolidated balance sheet data has been prepared
assuming that the merger took place on September 30, 1998, and combines the
unaudited historical consolidated balance sheets of Vodafone and AirTouch at
that date, as adjusted to U.K. GAAP, after giving effect to the pro forma
adjustments described in the notes to the unaudited pro forma consolidated
financial information.

RECENT DEVELOPMENTS (SEE PAGE 96)
 
    VODAFONE
 
    For the six months ended March 31, 1999, Vodafone's operating revenues were
in line with management's expectations. Customer growth continued to be strong
and is expected to remain robust for the mobile telecommunications industry
generally. Increasing competition in some markets may cause Vodafone ventures in
such markets to experience a slightly lower rate of increase in the number of
customers than in 1998. Vodafone expects the revenues of Vodafone AirTouch to
continue to grow, notwithstanding the industry-wide trend towards decreasing
average revenue per customer. Vodafone also expects capital expenditures to rise
in accordance with increasing usage and number of customers. Vodafone currently
expects to publish its results for the year ended March 31, 1999 on June 8,
1999.
 
    AIRTOUCH
 
    On April 22, 1999, AirTouch released its unaudited operating results for the
quarter ended March 31, 1999. AirTouch acquired the U.S. cellular and PCS
businesses of MediaOne Group, Inc. on April 6, 1998. Accordingly, AirTouch's
results for the quarter ended March 31, 1998, set forth below, do not include
the results of those acquired businesses for the periods prior to the
acquisition and, therefore, its comparability to the results for the quarter
ended March 31, 1999 is limited. Selected results for these periods include:

                      RISK FACTORS RELATING TO THE MERGER
 
EXPECTED BENEFITS FROM THE VODAFONE/AIRTOUCH COMBINATION MAY NOT BE REALIZED
 
    Vodafone and AirTouch entered into the merger agreement with the expectation
that the merger would result in cost savings and revenue enhancements. There can
be no assurance that the combined company will realize these anticipated
benefits in full or at all. If the expected benefits are not realized, the price
of the Vodafone AirTouch ADSs could be adversely affected.
 
THE EUROPEAN COMMISSION OR THE FCC MAY DELAY THE MERGER OR IMPOSE CONDITIONS
  WHICH REDUCE THE ANTICIPATED BENEFITS OF THE MERGER, EITHER OF WHICH COULD
  ADVERSELY AFFECT THE STOCK PRICE OF VODAFONE, AIRTOUCH OR VODAFONE AIRTOUCH
 
    Vodafone and AirTouch must obtain, as a condition to their obligation to
complete the merger, clearance under European Union competition laws and the
approval of the FCC without any restrictions or conditions that would have a
material adverse effect on Vodafone and AirTouch on a combined basis. There can
be no assurance that these consents and approvals will be obtained without
materially adverse restrictions or conditions. Depending on their nature and
extent, any restrictions, conditions or waivers may jeopardize or delay
completion of the merger or may lessen the anticipated benefits of the merger.
 
VALUE OF VODAFONE AIRTOUCH ADSS TO BE RECEIVED IN THE MERGER WILL FLUCTUATE
 
    The number of Vodafone AirTouch ADSs that AirTouch stockholders will receive
in the merger for each share of AirTouch common stock is fixed at 0.5 and the
merger agreement does not contain a mechanism to adjust the exchange ratio in
the event that the market price of the Vodafone ADSs declines. Therefore,
because the market price of Vodafone ADSs will fluctuate, the value at the time
of the merger of the consideration to be received by AirTouch stockholders will
depend on the market price at that time. There can be no assurance as to the
fair market value at the time of the merger of the consideration to be received
by AirTouch stockholders. For historical and current market prices of the
Vodafone ordinary shares and ADSs, see "MARKET PRICE AND DIVIDEND DATA."
 
THE REMOVAL OF AIRTOUCH FROM THE S&P 500 INDEX COULD ADVERSELY AFFECT THE MARKET
  PRICE FOR THE VODAFONE AIRTOUCH ADSS
 
    AirTouch common stock is presently included in the S&P 500 index. Mutual
funds and other investment vehicles whose investment objective is to track the
performance of the S&P 500 index currently hold a substantial amount of AirTouch
common stock. These funds will be required to sell their AirTouch shares (or the
Vodafone Airtouch ADSs they receive in the merger) if, as is likely after the
merger, AirTouch is removed from the S&P 500. These sales could adversely affect
the market price for the Vodafone AirTouch ADSs.
 
FORWARD-LOOKING STATEMENTS REGARDING BUSINESS AND OPERATIONS OF THE COMBINED
  COMPANY MAY PROVE INACCURATE
 
    Vodafone and AirTouch have made forward-looking statements in this document
and in documents incorporated by reference into this document concerning future
performance, costs, revenues and growth of Vodafone, AirTouch and/or Vodafone
AirTouch, industry and customer growth, wireless penetration rates and
statements regarding operational efficiencies from and benefits of the merger
and estimated company earnings. These statements may generally, but not always,
be identified by the use of words such as "anticipates," "should," "expects" or
"believes." By their nature, forward-looking statements involve risk and
uncertainty because they relate to events and depend on circumstances that
 
                                       20
<PAGE>
will occur in the future. Many factors could cause actual results and
developments to differ materially from those expressed or implied by these
forward-looking statements. These factors include:
 
    - the risk that the combined company will not achieve anticipated cost
      savings or revenue enhancements or that integration costs will exceed
      expectations,
 
    - changes in economic conditions in markets served by the operations of
      Vodafone, AirTouch and/ or Vodafone AirTouch which would adversely affect
      the level of demand for wireless services,
 
    - greater than anticipated competitive activity requiring reduced pricing
      and/or new product offerings or resulting in higher acquisition costs or
      slower customer growth,
 
    - greater than expected growth in customers and usage, requiring increased
      investment in network capacity,
 
    - the impact of new business opportunities requiring significant up-front
      investments,
 
    - the impact on capital spending from the deployment of new technologies,
      and
 
    - the possibility that technologies will not perform according to
      expectations or that vendors' performance will not meet the requirements
      of Vodafone, AirTouch and/or Vodafone AirTouch.
 
    Additional factors which could cause actual results and developments of
Vodafone AirTouch to differ from those expressed or implied by the
forward-looking statements are included in "Item 1. Business--Risk Factors" of
AirTouch's Annual Report on Form 10-K for the year ended December 31, 1998,
which is incorporated by reference into this proxy statement/prospectus.

    - Address procedural matters that may properly come before the special
      meeting or any adjournment or postponement of the special meeting.
 
RECORD DATE

to vote at, the special meeting.
 
    - All AirTouch stockholders of record, including holders of AirTouch Class
      C, Class D and Class E preferred stock, at the close of business on the
      record date are entitled to notice of the AirTouch special meeting.
 
    - Only holders of record of AirTouch common stock and AirTouch Class B
      preferred stock at the close of business on the record date are entitled

HOW SHARES WILL BE VOTED AT THE SPECIAL MEETING
 
    Proxies that are properly executed by holders of AirTouch common stock and
AirTouch Class B preferred stock, if received in time for the special meeting
and not subsequently revoked, will be voted at the special meeting in accordance
with the instructions given in the proxies. Proxies that are properly executed
but do not contain instructions with respect to the proposals for approval of
the merger and/or the internal reorganization will be voted "FOR" approval of
the transaction for which the proxy does not contain instructions.
 
    Stockholders who hold their AirTouch stock in their own name may call (800)
650-3514 toll-free to authorize the board of directors of AirTouch to execute a
proxy to vote their shares. The enclosed proxy card contains the specific
instructions to be followed by AirTouch stockholders for telephone voting.
AirTouch stockholders whose shares are held in the name of a bank or broker
should follow the voting instructions provided by the bank or broker. The
availability of telephone voting will depend on the voting processes of the bank
or broker.
 
                                       22
<PAGE>
    AS NOTED IN "APPRAISAL RIGHTS," A HOLDER OF AIRTOUCH COMMON STOCK WHO VOTES
IN FAVOR OF THE MERGER OR THE INTERNAL REORGANIZATION WILL FORFEIT HIS OR HER
APPRAISAL RIGHTS UNDER DELAWARE LAW WITH RESPECT TO THESE TRANSACTIONS.
 
    AIRTOUCH STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THE ENCLOSED
PROXY CARD. IF THE MERGER IS COMPLETED, VODAFONE AIRTOUCH WILL FURNISH AIRTOUCH
STOCKHOLDERS WITH INSTRUCTIONS FOR EXCHANGING THEIR SHARES OF AIRTOUCH COMMON
STOCK FOR VODAFONE AIRTOUCH ADSS AT THAT TIME.
 
HOW TO REVOKE A PROXY
 
    If you are a stockholder holding AirTouch shares in your own name, you may
revoke a previously given proxy at any time prior to its exercise by:
 
    - delivering, prior to the special meeting, to the The Bank of New York, a
      written notice of revocation or a proxy having a later date or time than
      the executed proxy; or
 
    - voting by telephone after the date of a previously given proxy; or
 
    - voting in person at the special meeting.
 
    Attendance at the special meeting will not by itself constitute revocation
of the proxy granted by the proxy card. Stockholders must mail written notices
of revocation to:
 
       The Bank of New York
       P.O. Box 11466
       New York, New York 10203-0466
 
Written notices of revocation must be received before stockholders vote at the
AirTouch special meeting. Any revocation by telephone must be done prior to the
time of the special meeting.
 
    If you do not hold your AirTouch shares in your own name, you may revoke a
previously given proxy by following the revocation instructions provided by the
bank, broker or other party who is the registered owner of the shares.
 
REQUIRED VOTE; QUORUM
 
    AirTouch stockholders will vote separately on proposals to approve and adopt
each of the merger agreement and the agreement providing for the internal
reorganization. The merger may only be completed if the internal reorganization
is completed. The affirmative vote of the holders of AirTouch common stock and
AirTouch Class B preferred stock representing a majority of the voting power of
the shares of AirTouch common stock and the shares of AirTouch Class B preferred
stock entitled to vote at the special meeting, voting as a single class, is
required to approve and adopt each of the merger agreement and the agreement
providing for the internal reorganization. Each share of AirTouch common stock
outstanding on the record date is entitled to one vote. Each share of AirTouch
Class B preferred stock outstanding on the record date is entitled to
four-fifths of one vote. There are no other classes of voting securities of
AirTouch presently outstanding.
 
    As of the record date, directors and executive officers of AirTouch and
their affiliates owned approximately 0.10% and 0.21% of the outstanding shares
of AirTouch common stock and AirTouch Class B preferred stock, respectively. See
"DIRECTORS AND MANAGEMENT OF VODAFONE AIRTOUCH FOLLOWING THE MERGER--Stock
Ownership of Directors, Executive Officers and Five Percent Stockholders."
 
    Brokers and nominees are precluded from exercising their voting discretion
on the approval and adoption of the merger agreement and the agreement providing
for the internal reorganization and, for this reason, absent specific
instructions from the beneficial owner of shares of AirTouch common stock or
AirTouch Class B preferred stock, may not vote these shares. Shares that are not
voted because
 
                                       23
<PAGE>
brokers did not receive instructions are referred to as "broker non-votes."
Holders of a majority in voting power of the AirTouch common stock and AirTouch
Class B preferred stock outstanding on the record date must be present in person
or by proxy at the special meeting to constitute a quorum. Abstentions and
broker non-votes are counted as present or represented for purposes of
determining a quorum for the special meeting. Because the affirmative vote of
the holders of a majority of the voting power of AirTouch common stock and
AirTouch Class B preferred stock, voting as a single class, is required for
approval and adoption of each of the merger agreement and the agreement
providing for the internal reorganization, AN ABSTENTION, UNRETURNED PROXY OR
BROKER NON-VOTE WILL BE TREATED AS A VOTE AGAINST APPROVAL AND ADOPTION OF THE
MERGER AGREEMENT AND THE AGREEMENT PROVIDING FOR THE INTERNAL REORGANIZATION.
 
APPRAISAL RIGHTS
 
    For a complete discussion of the appraisal rights under Delaware law of
holders of AirTouch common stock, AirTouch Class D preferred stock and AirTouch
Class E preferred stock in connection with the merger and the internal
reorganization, see the section entitled "APPRAISAL RIGHTS" beginning on page
87. Holders of AirTouch Class B and AirTouch Class C preferred stock are not
entitled to appraisal rights under Delaware law in connection with the merger or
the internal reorganization. However, holders of AirTouch Class B and AirTouch
Class C preferred stock who converted their shares into AirTouch common stock
prior to the record date for the special meeting are entitled to assert
appraisal rights with respect to that AirTouch common stock in connection with
the merger.
 
SOLICITATION OF PROXIES
 
    AirTouch will bear the costs of the special meeting and of soliciting
proxies therefor. Vodafone and AirTouch will share equally the amount of the
filing fees and the other expenses incurred in connection with the cost of
filing, printing and distributing this proxy statement/prospectus. In addition
to solicitation by mail, the directors, officers and employees of AirTouch may
also solicit proxies from stockholders by telephone, facsimile, telegram or
other electronic means or in person. AirTouch will make arrangements with
brokerages and others custodians, nominees and fiduciaries to send the proxy
materials to beneficial owners, and AirTouch will reimburse those brokerage
houses and custodians for their reasonable expenses in doing so. Georgeson &
Company Inc. will assist in the solicitation of proxies by AirTouch for a fee
not to exceed $100,000 plus reasonable out-of-pocket expenses.

      matters which are required to give effect to the merger or to satisfy

           Vodafone AirTouch ordinary shares of nominal value 5p each; and
 
       (2) to approve the continued operation of the AirTouch employee share
           plans by Vodafone AirTouch for at least one year after the merger as
           required by the merger agreement.

      AirTouch shareholders and to allot generally additional relevant
      securities up to an aggregate nominal value of L99,274,601. Relevant

    - Resolution 5--to change the name of Vodafone to "Vodafone AirTouch Public
      Limited Company."

      AirTouch: Samuel L. Ginn, Arun Sarin, Mohanbir S. Gyani, Michael J.

    - Resolution 13--to increase the aggregate remuneration authorized to be
      payable to non-executive directors of Vodafone AirTouch after the merger
      to an amount not exceeding L1 million per year.
 
    - Resolution 14--to make changes to Vodafone's articles of association to
      give effect to terms of the merger agreement, including:
 
       (1) providing that all special and extraordinary resolutions will be
           taken on a poll and all ordinary resolutions will be conducted by
           show of hands (unless a poll is demanded in accordance with the
           memorandum and articles of association or the U.K. Companies Act);
 
       (2) permitting multiple proxies to have the right to attend, speak and
           vote on a poll or a show of hands at Vodafone AirTouch general
           meetings;
 
                                       25

           have a casting vote;

           otherwise; and
 
       (5) allowing multiple proxies themselves to appoint a substitute.
 
    - Resolution 15--if the redenomination contemplated by Resolution 18 does
      not take effect, to give the Vodafone AirTouch board the power to disapply
      shareholders' preemption rights in respect of issues for cash of ordinary
      shares with an aggregate nominal value of L15,111,934, being approximately
      5% of the expected Vodafone AirTouch issued ordinary share capital upon
      completion of the merger. This authority will expire on the earlier of the
      date of Vodafone AirTouch's next annual general meeting in 2000 and August
      24, 2000.
 
    - Resolution 16--to approve the introduction of the new Vodafone AirTouch
      share schemes.
 
    - Resolution 17--to approve a change to the existing Vodafone Group long
      term incentive plan.
 
    - Resolution 18--
 
       (1) to authorize transactions required to effect the redenomination of
           the nominal value of each of the Vodafone ordinary shares from L into
           $;
 
       (2) to increase the authorized share capital of Vodafone by
 
           (a) creating 50,000 "B" 7% cumulative fixed rate shares of L1 each
               and 8,160,000,000 ordinary shares of U.S.$0.10 each,
 
           (b) giving the board of directors of Vodafone the authority to allot
 
               (i) 50,000 "B" 7% cumulative fixed rate shares of L1 each so
                   that, as required by English law, Vodafone will have issued
                   share capital of at least L50,000 following the
                   redenomination of the Vodafone ordinary shares,
 
               (ii) redenominated shares with an aggregate nominal value of
                   approximately $309,950,798 to the existing Vodafone
                   shareholders and
 
               (iii) redenominated shares with an aggregate nominal value of
                   approximately $307,500,000 to AirTouch common stockholders as
                   shares to be issued in the merger, and
 
           (c) providing the Vodafone AirTouch directors with additional
               authority to allot relevant securities up to an aggregate nominal
               value of $198,549,202, being approximately 32% of the expected
               Vodafone AirTouch issued ordinary share capital upon completion
               of the merger.
 
           This authority will expire on the earlier of the date of Vodafone
           AirTouch's next annual general meeting in 2000 and August 24, 2000,
           except the authority granted in (2)(b)(i) will terminate on March 31,
           2000.
 
    - Resolution 19--to give the Vodafone AirTouch board the power to disapply
      shareholders' preemption rights in respect of issues for cash of ordinary
      shares with an aggregate nominal value of $30,223,868, being approximately
      5% of the expected Vodafone AirTouch issued ordinary share capital upon
      completion of the merger. This authority will expire on the earlier of the
      date of Vodafone AirTouch's next annual general meeting in 2000 and August
      24, 2000 and will only take effect if Resolution 18 takes effect.
 
                                       26
<PAGE>
    - Resolutions 20 and 21--to approve the repurchase by Vodafone AirTouch of
      up to 5% of its share capital at a price not exceeding 105% of the average
      middle market closing price of these shares on the five trading days prior
      to the date of purchase.
 
    - Resolution 22--to amend the Vodafone articles of association so as to
      adopt a "plain English" set of articles to be effective from the end of
      the Vodafone shareholders' meeting.
 
    - Resolution 23--to adopt a new set of "plain English" articles of
      association upon completion of the merger so that all changes that are
      required to give effect to (1) certain terms of the merger, and (2) if the
      redenomination takes effect, the redenomination, are incorporated and
      adopted therein.
 
    At the Vodafone extraordinary general meeting, on a show of hands, every
shareholder of Vodafone who is present in person or, if a corporation, present
by proxy, shall have one vote and, on a poll, every shareholder of Vodafone who
is present in person or by proxy shall have one vote for each Vodafone ordinary
share held. Resolutions 4, 5, 14, 15 and 18 through 23 are special resolutions
and will require the approval of at least 75% of the votes cast by Vodafone
shareholders present in person, or if on a poll, in person or by proxy, at the
Vodafone shareholders' meeting. The other resolutions are ordinary resolutions
and will require the approval of at least 50% of the votes cast by Vodafone
shareholders present in person, or if on a poll, in person or by proxy, at the
Vodafone shareholders' meeting. The standard quorum requirement of two members
will apply.
 
RESOLUTIONS REQUIRED FOR THE MERGER
 
    The Vodafone shareholders must approve Resolution 3 and, unless Resolution
18 is passed, Resolution 4 in order to complete the merger. The election of the
additional directors nominated by AirTouch in Resolutions 6 to 12 by the
necessary majorities and the approval of Resolutions 5, 13, and 14 are a
condition to AirTouch's obligation to consummate the merger, and the merger will
not become effective unless these Resolutions are approved by the necessary
votes or AirTouch waives the requirement for approval. Approval of the Vodafone
shareholders of Resolutions 15 through 23 is not required to complete the
merger. Resolutions 5 through 16, 20, 21 and 23 will not become effective unless
Resolutions 3 and 4 are passed.
 
    The merger is not conditional upon Resolution 18 being passed and the
redenomination becoming effective. However, as the redenomination is being
proposed to facilitate the merger, the Vodafone board will not implement the
redenomination unless and until each of the conditions to the merger is likely
to be satisfied or waived.
 
PURPOSE OF RESOLUTIONS 3, 4, 15, 18 AND 19
 
    - Resolutions 3, 4 and 18 provide for
 
       - an increase in ordinary share capital and
 
       - authority for the board to allot shares.
 
    - Both Resolutions 15 and 19 provide for the disapplication of preemption
      rights.
 
    - These are provided for twice in each case, as the authorities must be in
      either U.S. dollars or pounds sterling depending on whether or not the
      redenomination has occurred.
 
    - The increase in authorized share capital and the increase in the board
      allotment authority will enable the board to allot Vodafone AirTouch
      ordinary shares pursuant to the merger and maintain a sufficient level of
      authority to allot additional Vodafone AirTouch ordinary shares up to a
      nominal amount of L99,274,601 or $198,549,202 until the earlier of the
      date of Vodafone's next annual general meeting in 2000 and August 24,
      2000.
 
                                       27
<PAGE>
    - Disapplying preemption rights will permit directors to allot up to
      302,238,868 Vodafone AirTouch ordinary shares for cash without being
      required to offer them to existing shareholders.
 
    - Except pursuant to the merger, the redenomination of the Vodafone ordinary
      shares, the issue of up to 50,000 "B" 7% cumulative fixed rate shares of
      L1 each, the issue of shares under Vodafone's scrip dividend scheme and
      the exercise of options under Vodafone's option schemes, the directors of
      Vodafone have no present intention to allot Vodafone AirTouch ordinary
      shares, and after the merger no issue of shares which would result in a
      change of control will take effect without the consent of Vodafone
      AirTouch shareholders in a general meeting.
 
EFFECT OF FAILURE TO APPROVE RESOLUTION 18
 
    If the Vodafone shareholders fail to approve Resolution 18 and the Vodafone
ordinary shares are not redenominated into U.S. dollars, there will be no direct
effect on AirTouch stockholders. There will be no material differences between
ordinary shares denominated in pounds sterling and ordinary shares denominated
in U.S. dollars. However, a stamp duty reserve tax liability of 1.5% of the
issue price of the Vodafone AirTouch ordinary shares issued to AirTouch
stockholders in the form of Vodafone AirTouch ADSs would arise and be jointly
payable by Vodafone and AirTouch when Vodafone AirTouch ADSs are issued. This
tax liability is estimated to be approximately L491 million ($792 million),

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
    Both Vodafone and AirTouch are leading international providers of mobile
telecommunications services. Vodafone provides cellular service in the United
Kingdom and has interests in wireless companies operating in 12 other countries.
AirTouch operates cellular and PCS networks that reach most of the major markets
in the United States and has interests in wireless companies operating in 12
other countries. Vodafone and AirTouch have highly complementary operations and
together have interests in companies that provide service in 13 European
countries, including all major European markets. At the time of the execution of
the merger agreement, the companies owned interests in competing ventures only
in Germany.
 
    As is common in the wireless telecommunications industry, AirTouch and,
outside the U.K., Vodafone conduct much of their business through partnerships
and other joint ventures. Internationally, AirTouch generally operates through
joint ventures and other consortia, including in Sweden and Egypt, where
Vodafone and AirTouch both have ownership interests in the same ventures.
Vodafone and AirTouch are also both limited partners in Globalstar, L.P., a
satellite communications venture. In the United States, AirTouch is a partner in
a number of partnerships, including with Bell Atlantic in PrimeCo Personal
Communications, L.P., a company providing PCS services in more than 30 major
cities, and in TOMCOM, L.P., a partnership formed to provide technical,
operating and marketing services for the partners' United States wireless
properties.
 
    In light of the complementary nature of AirTouch's and Vodafone's European
properties, in late 1996 and on several occasions in 1997, executives of
Vodafone and AirTouch explored possible operational synergies. Alternatives
discussed included a joint venture, contractual roaming and purchasing
arrangements and a merger of the companies. The discussions were conceptual
only, and no subsequent steps were taken.
 
    In September and early October of 1998, Chris Gent, chief executive of
Vodafone, Sam Ginn, chairman and chief executive officer of AirTouch, and other
executives of the companies met on several occasions. The parties discussed the
possible benefits and principal objectives of a potential merger as well as
issues regarding the then current valuation of AirTouch and how management of a
combined company would be organized. Those discussions, however, were
inconclusive on many important issues and did not result in the formation of a
combination proposal.
 
    On October 14, 1998, the AirTouch board held its annual meeting to discuss
the company's strategic direction. The AirTouch board analyzed the United States
and international wireless environments and AirTouch's position as an
independent company as well as the strategic aspects of a potential merger with
Vodafone. The AirTouch board also discussed the strategic aspects of the
formation of a new wireless company with Bell Atlantic in response to an
indication by Bell Atlantic in September 1998 that it might make a proposal of
this kind to AirTouch in the near future. The AirTouch board reaffirmed
AirTouch's strategy as an independent company but determined that management
should be open to discussions with both interested companies to explore further
the potential benefits of both transactions.
 
    On October 21, 1998, Messrs. Gent and Ginn had a telephone conversation to
discuss again several of the issues key to a potential merger but were unable to
resolve them and agreed to terminate their negotiations. There were no further
negotiations between executives or other employees of the two companies until
the week of January 4, 1999, although in the interim the two companies'
financial advisors had several discussions regarding the financial aspects of a
potential merger.
 
    On November 13, 1998, Bell Atlantic presented its proposal to AirTouch
regarding the formation of a new wireless company. The proposal contemplated
that both Bell Atlantic and GTE, which
 
                                       29
<PAGE>
companies have entered into a merger agreement, would contribute their wireless
assets to AirTouch and receive a controlling interest in the new company. During
November and December, senior management of AirTouch and Bell Atlantic engaged
in discussions regarding the Bell Atlantic proposal and, in late November,
AirTouch and Bell Atlantic also began to explore a possible merger of AirTouch
with Bell Atlantic in exchange for Bell Atlantic stock.
 
    On December 31, 1998, media reports circulated to the effect that Bell
Atlantic and AirTouch were in merger discussions. Over the next two days, Mr.
Gent and Ken Hydon, financial director of Vodafone, and representatives of
Goldman Sachs International discussed the Bell Atlantic proposal described in
the media reports and the propriety and timing of informing AirTouch of
Vodafone's renewed interest in a transaction with AirTouch. On January 2, 1999,
Vodafone sent AirTouch a letter indicating its desire to make a merger proposal
but did not set forth the elements of its proposal. On January 3, 1999 the
AirTouch board had a special meeting to discuss the status of merger
negotiations and AirTouch's options. Although AirTouch has a long-standing
policy not to comment on market speculation, in light of Bell Atlantic's stated
intention to issue a press release and the extensive and detailed media coverage
of the AirTouch and Bell Atlantic discussions, on January 3, 1999 AirTouch and
Bell Atlantic issued a joint press release confirming that they were in merger
discussions. At or about that time, AirTouch's financial advisors requested
that, if Vodafone was interested in making a proposal, it make a specific
proposal promptly.
 
    By letter dated January 4, 1999, Vodafone invited AirTouch to enter into
discussions for a merger in which AirTouch stockholders would receive five
Vodafone shares, equivalent to 0.5 of an ADS, and $6.00 in cash for each share
of AirTouch common stock. Vodafone structured the offer as a share exchange with
a cash element in order both to make the offer attractive to AirTouch in light
of competing proposals and, at the same time, fair to Vodafone as well as to
ensure tax-free treatment (to the extent possible) for AirTouch's U.S.
stockholders.
 
    Vodafone's approach was rumored in the media, and on January 5, 1999, in
response to a request from the London Stock Exchange in light of the media
rumors, Vodafone issued a press release confirming that it had made a proposal
to AirTouch. On that same day, AirTouch issued its own press release stating
that it had received a merger proposal from Vodafone. Mr. Hydon, Mohan Gyani,
executive vice president and chief financial officer of AirTouch, and the
companies' financial advisors met on January 6 and January 7, 1999 to discuss
the financial terms of Vodafone's proposal and the potential cost savings and
revenue opportunities which might be achieved through a merger.
 
    On January 7, 1999 and January 10, 1999, the AirTouch board held special
meetings to discuss AirTouch's strategic alternatives, the status of
negotiations with Bell Atlantic and Vodafone, the potential benefits and
disadvantages of each of the proposed transactions and the status of due
diligence and related legal and financial issues. At the meetings, the AirTouch
board received advice from Morgan Stanley regarding the financial aspects of
both proposals and from AirTouch's legal counsel regarding the relevant legal
considerations in evaluating AirTouch's options. At the January 7 meeting, the
AirTouch board was also briefed about a possible MCI WorldCom proposal as a
result of an exploratory call from that company's chairman, Bernard Ebbers, to
Mr. Ginn. However, later that week Mr. Ebbers informed Mr. Ginn that MCI
WorldCom would not be making an acquisition proposal.
 
    Following the January 10, 1999 meeting of the AirTouch board, Vodafone and
AirTouch, advised by their respective financial advisors and lawyers, negotiated
the terms and conditions of the merger agreement. At the same time, AirTouch
continued its merger negotiations with Bell Atlantic. AirTouch informed both
Bell Atlantic and Vodafone that it intended to present both companies' final
proposals and the final forms of the respective merger agreements to the
AirTouch board at a special meeting on January 15.
 
                                       30
<PAGE>
    The financial terms of the merger being proposed by Bell Atlantic varied
during the period of negotiations between Bell Atlantic and AirTouch, although
each proposal after late November 1998 involved the exchange of Bell Atlantic
common stock for AirTouch common stock. During the week of January 10, Bell
Atlantic's proposal involved an exchange of each share of AirTouch common stock
for 1.54 shares of Bell Atlantic common stock, subject to an upward adjustment
in the exchange ratio commencing in nine months to reflect dividend payments on
Bell Atlantic common stock, and was conditioned on the transaction being
accounted for as a pooling of interests under U.S. GAAP. Bell Atlantic's
proposal also involved a "collar" pursuant to which the exchange ratio would be
adjusted to produce a price of $80.08 if the price of Bell Atlantic common stock
ranged from $48 to $52. If the average closing price of Bell Atlantic common
stock was below $48 during the specified period, the exchange ratio would be
1.6683; if the price was above $52, the exchange ratio would be 1.54. The
closing price per share of Bell Atlantic's common stock on the NYSE ranged from
$53 1/8 to $54 15/16 during the week of January 11.
 
    On January 14, 1999, the Vodafone board met and considered, together with
its financial advisors, the progress of the negotiations with AirTouch of the
merger agreement and the results of Vodafone's due diligence with respect to
AirTouch. The Vodafone board confirmed its view of the strategic importance to
Vodafone's future of the proposed merger with AirTouch. The Vodafone board also
discussed the possibility of increasing the cash component and therefore the
value of its then current offer to AirTouch following indications received by
the executive management of Vodafone from AirTouch that an increase in the cash
consideration would substantially improve the competitiveness of Vodafone's
offer as compared to Bell Atlantic's offer. The Vodafone board then considered
an increase in the terms of Vodafone's offer from five Vodafone shares and $6.00
in cash for each share of common stock of AirTouch to five Vodafone shares and
$9.00 in cash. At the meeting, Goldman Sachs International rendered its oral
opinion to the Vodafone board, subsequently confirmed in writing, that the
increased merger consideration contemplated was fair from a financial point of
view to Vodafone. The Vodafone board then unanimously approved the merger
agreement and the offer of five Vodafone shares and up to $9.00 in cash for each
share of common stock of AirTouch in the hope of securing a successful
transaction with AirTouch.
 
    On January 15, 1999, immediately prior to the AirTouch board meeting,
Vodafone increased its offer to five shares of Vodafone and $9.00 in cash for
each share of AirTouch common stock. Senior management of Bell Atlantic
indicated that it was prepared to raise its offer, but did not specify by what
amount and further indicated both that the exchange ratio would not reach 1.60
Bell Atlantic shares for each AirTouch share and also that no "collar" would be
provided to the stockholders of AirTouch.
 
    At the AirTouch board meeting, AirTouch's executive management reviewed the
principal terms of the two offers and the results of AirTouch's due diligence of
the two companies. Morgan Stanley then presented its financial analysis of each
proposed transaction and AirTouch's legal counsel reviewed the two proposed
merger agreements as well as the standards of Delaware law applicable to the
board's decision. The AirTouch board, executive management, legal counsel and
Morgan Stanley engaged in a discussion of the two proposals. Morgan Stanley
delivered its oral opinion, which was later confirmed in a written opinion dated
as of January 15, 1999, that, as of that date and based upon and subject to the
matters stated in its opinion, the merger consideration offered by Vodafone was
fair from a financial point of view to the holders of AirTouch common stock. See
"--Opinions of Financial Advisors--Opinion of AirTouch's Financial Advisor" for
a description of the Morgan Stanley opinion. The AirTouch board concluded that
the Vodafone proposal was superior to the Bell Atlantic proposal and in the best
interests of AirTouch and its stockholders for the reasons set forth below under
"--Recommendation of the AirTouch Board; Additional Considerations of the
AirTouch Board." The AirTouch board voted unanimously to approve and declare
advisable the merger, the merger agreement
 
                                       31
<PAGE>
and each of the transactions contemplated thereby, and to recommend that the
AirTouch stockholders approve and adopt the merger agreement and the agreement
providing for the internal reorganization.
 
    After the January 15 meeting of the AirTouch board, the parties executed the
merger agreement. On January 15, 1999, Vodafone and AirTouch issued a joint
press release announcing the execution of the merger agreement.
 
REASONS FOR THE MERGER
 
    Vodafone and AirTouch believe that the merger of two of the world's leading
mobile telecommunications companies will create a more competitive, global
wireless telecommunications company than either Vodafone or AirTouch would be on
its own and will generate significant opportunities to deliver greater value to
shareholders.
 
    - SHARED STRATEGIC VISION.  The global market for mobile telecommunications
is undergoing rapid growth as consumers have endorsed the benefits of mobile
telephony, enhanced by increasingly lightweight, secure and attractive
equipment. Both Vodafone and AirTouch believe that mobile telecommunications
will continue to be one of the fastest growing segments of the
telecommunications industry as, over time, mobile voice telephony will replace
large amounts of telecommunications traffic currently carried by fixed line
networks and will serve as a major platform for voice and data communications.
The companies expect that the combined entity will be in a better position to
take advantage of the opportunities presented by the rapidly growing mobile
telecommunications industry and data services market. Vodafone and AirTouch
believe that mobile penetration rates in most developed countries will reach 50%
by the year 2003 and will reach 55% in the United States and 65% in most
developed European countries by 2005.
 
    - SCALE, OPERATIONAL STRENGTH AND COMPLEMENTARY ASSETS.
 
    - The combination of Vodafone and AirTouch will create the world's largest
      mobile telecommunications company, with a significant presence in the
      United Kingdom, the United States, continental Europe and the Asia Pacific
      region.
 
    - The scale and scope of the operations in which the merged enterprise will
      have an interest are expected to place it in an advantageous position to
      capitalize on the anticipated growth of the industry, to provide greater
      global telecommunications coverage and to become the "operator of choice"
      for international companies, business travelers and travel-minded
      consumers.
 
    - Because of the complementary nature of Vodafone's and AirTouch's assets,
      the merged entity will have interests in operations in all of Europe's
      major markets, making it a more attractive partner for other international
      fixed and mobile telecommunications providers as well as a more desirable
      customer for hardware and software suppliers.
 
    - The combined group's operational strength and scale are expected to
      enhance its ability to develop existing networks, to be at the forefront
      of the provision of technologically advanced products and services,
      particularly the development of third generation mobile telephony, and to
      make strategic acquisitions.
 
    - SYNERGIES.  Vodafone and AirTouch believe that substantial cost savings
are likely to accrue as a result of the combination of the two companies. The
companies estimate that the merger will result in after-tax net cash flow
savings of approximately $340 million per year by the year ending March 31,
2002. The net present value of these estimated savings is approximately $3.6
billion, based on a 9% discount rate. The cost savings are expected to arise
from global purchasing and operating efficiencies, including volume discounts on
worldwide purchases of cellular handsets, infrastructure and other assets, lower
leased line costs, a more efficient contiguous European voice and data network
and savings in the development and purchase of third generation mobile handsets,
infrastructure and software. In
 
                                       32
<PAGE>
addition, Vodafone and AirTouch believe that the combined entity will be able to
achieve certain revenue enhancements through more extensive international
coverage and through the bundling of services for corporate customers that
operate on a multinational basis, business travelers and travel-minded
consumers.
 
RECOMMENDATION OF THE AIRTOUCH BOARD; ADDITIONAL CONSIDERATIONS OF THE AIRTOUCH
  BOARD
 
    At its meeting on January 15, 1999, the board of directors of AirTouch, by
unanimous vote, determined that the merger was in the best interests of AirTouch
and AirTouch stockholders, approved and declared advisable the merger and
related transactions and recommended that the stockholders of AirTouch approve
and adopt the merger agreement and the agreement governing the internal
reorganization.
 
    In the course of reaching its determinations, the AirTouch board consulted
with AirTouch's management, as well as its financial and legal advisors. The
AirTouch board considered the following factors:
 
    - The reasons described under "--Reasons for the Merger;"
 
    - The oral opinion, later confirmed in writing, delivered by Morgan Stanley
      that, as of the date of the opinion, the consideration offered by Vodafone
      in the merger was fair to the AirTouch stockholders from a financial point
      of view;
 
    - The board's determination that the consideration offered by Vodafone was
      superior to the consideration that AirTouch stockholders would receive
      under the Bell Atlantic proposal, based on the analyses and presentations
      prepared by Morgan Stanley, including analyses of the then current market
      price, historical trading prices, market prices on a fully distributed
      basis, i.e., the anticipated trading prices of Vodafone and Bell Atlantic
      securities upon completion of the merger and after the initial post-merger
      period of redistribution of these securities in the market, and prospects
      of each of AirTouch, Vodafone and Bell Atlantic. In reaching this
      determination, the board considered in particular:
 
        -- that the Bell Atlantic proposal had a current market value of
           approximately $83 per share of AirTouch common stock, based on the
           $53.8125 closing price of Bell Atlantic common stock on January 14,
           1999, and contained a collar that would maintain a current market
           value of $80.08 per share if the price of Bell Atlantic common stock
           during a specified period prior to closing was between $52 and $48;
 
        -- that the Vodafone proposal had a current market value of $97 per
           share of AirTouch common stock based on the closing price of Vodafone
           ordinary shares on January 15, 1999 of L10.685 ($17.65);
 
        -- that following the merger, the market value of the Vodafone ADSs to
           be received by AirTouch stockholders under the Vodafone proposal
           might decrease; however, so long as Vodafone ADSs trade above $148,
           the market value of the Vodafone proposal would exceed the market
           value of Bell Atlantic proposal assuming the price of Bell Atlantic
           common stock remained constant; and
 
        -- that following a merger with Bell Atlantic, the market value of the
           Bell Atlantic common stock to be received under the Bell Atlantic
           proposal might decrease, particularly in light of the advice provided
           to the board by AirTouch's management and financial advisor that the
           proposed Bell Atlantic transaction would be dilutive by more than 10%
           to Bell Atlantic's earnings per share through 2002;
 
                                       33
<PAGE>
    - The expectation that the AirTouch stockholders will hold slightly less
      than 50% of the total issued share capital of the combined company;
 
    - The fact that, in light of the substantial holdings of the AirTouch
      stockholders in the share capital of the combined company, half of the
      board of directors of the combined company will include designees from the
      AirTouch board and that key members of senior management of AirTouch were
      expected to play a significant role in the management of the combined
      company;
 
    - The board's determination that the Vodafone transaction would involve less
      regulatory uncertainty, would otherwise be likely to close more quickly
      and would provide greater operational flexibility to AirTouch pending
      closing than would the Bell Atlantic proposal;
 
    - The fact that the merger can be consummated, except with respect to cash
      received, as a tax-free reorganization under the U.S. tax code and, unlike
      the Bell Atlantic proposal, is not conditioned on obtaining any specific
      accounting treatment, such as pooling of interests accounting under U.S.
      GAAP or merger accounting under U.K. GAAP;
 
    - The board's view that it was unlikely that AirTouch would receive any
      other proposals given that, in addition to the Vodafone proposal and the
      Bell Atlantic proposal, MCI WorldCom made and later withdrew a preliminary
      indication of interest in making a proposal to AirTouch, that these
      developments were reported publicly, and that AirTouch had not received
      any other proposal or indication of interest; and
 
    - That the merger agreement grants AirTouch the right, with respect to any
      proposal subsequently made to AirTouch that the AirTouch board determines
      in good faith to be superior to the merger, to provide information, engage
      in negotiations and change its recommendation to stockholders.
 
    The AirTouch board also considered the following potentially negative
factors:
 
    - The board's determination that a combination with Vodafone, unlike a
      combination with Bell Atlantic, would not address the major U.S. strategic
      issue facing AirTouch of creating a national footprint in the U.S.,
      although the board determined that the combined company should be able to
      achieve a U.S. national footprint or its equivalent through other means;
 
    - The board's consideration that Bell Atlantic is a larger, more diversified
      company than Vodafone, that Vodafone shares are selling at a higher price
      to earnings ratio than the shares of companies in its peer group in the
      U.S. and that the Vodafone share price has been more volatile than the
      Bell Atlantic share price, resulting in the board's view that a
      combination with Vodafone may be subject to greater market price risk than
      would a combination with Bell Atlantic;
 
    - An analysis prepared by Morgan Stanley which reflected that, on a relative
      contribution basis, AirTouch's contribution to various earnings
      measurements ranged from 57.8% to 68.4%, compared to the pro forma
      ownership of Vodafone AirTouch by AirTouch stockholders implied by the
      effective exchange ratio of 53%;
 
    - The board's consideration that AirTouch might have had to repurchase
      AirTouch shares to facilitate the tax planning for the merger;
 
    - The board's consideration that Vodafone, and possibly AirTouch, will incur
      significant additional indebtedness to finance the cash portion of the
      merger consideration;
 
    - The board's consideration that Vodafone's and AirTouch's non-controlling
      positions in certain key markets may limit the combined company's ability
      to achieve all of the potential synergies;
 
                                       34
<PAGE>
    - The board's consideration that the combined company would not be
      incorporated in the United States;
 
    - The board's consideration that the principal trading market for Vodafone
      ordinary shares is, and will continue to be after the merger, the London
      Stock Exchange, although the board also noted that the Vodafone AirTouch
      ADSs will be listed on the NYSE and will provide a more accessible trading
      vehicle than Vodafone AirTouch ordinary shares for U.S. shareholders; and
 
    - The board's recognition that the termination payment provisions of the
      merger agreement could discourage alternative proposals being made to
      AirTouch thereafter, although the board determined that it was unlikely
      that AirTouch would receive alternative proposals in any event, and that
      these provisions are customary for transactions of this type, provide for
      amounts within the range that is customary for transactions of this size,
      and were necessary to induce Vodafone to enter into the merger agreement.
 
    The discussion above of the factors considered by the board of directors of
AirTouch is not intended to be exhaustive but includes the material factors
considered by the AirTouch board. In view of the wide variety of factors
considered by the AirTouch board in connection with its evaluation of the merger
and the complexity of these matters, the AirTouch board did not consider it
practical, and did not attempt, to quantify, rank or otherwise assign relative
weights to the specific factors it considered in reaching its decision. The
AirTouch board conducted a discussion of the factors described above, including
asking questions of AirTouch's management and AirTouch's legal and financial
advisors, and reached unanimous consensus that the merger was in the best
interests of AirTouch and the AirTouch stockholders. In considering the factors
described above, individual members of the AirTouch board may have given
different weight to different factors. The AirTouch board relied on the
experience and expertise of its financial advisor for quantitative analysis of
the financial terms of the merger. See "--Opinions of Financial
Advisors--Opinion of AirTouch's Financial Advisor."
 
    THE BOARD OF DIRECTORS OF AIRTOUCH HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, THE MERGER AND EACH OF THE TRANSACTIONS CONTEMPLATED THEREBY AND
DECLARED THEIR ADVISABILITY. ACCORDINGLY, THE AIRTOUCH BOARD RECOMMENDS THAT
AIRTOUCH STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT
AND "FOR" APPROVAL AND ADOPTION OF THE AGREEMENT PROVIDING FOR THE INTERNAL
REORGANIZATION.
 
ADDITIONAL CONSIDERATIONS OF THE VODAFONE BOARD
 
    At its meeting on January 14, 1999, the board of directors of Vodafone
unanimously approved the offer of five Vodafone shares and up to $9.00 in cash
for each common share of AirTouch and the merger agreement and the transactions
contemplated thereby.
 
    In the course of reaching its conclusions on the merger, the Vodafone board
consulted with Vodafone's management as well as its financial, legal and
accounting advisors and considered the following factors:
 
    - The reasons described under "--Reasons for the Merger;"
 
    - The oral opinion, later confirmed in writing, delivered by Goldman Sachs
      International, that, as of the date of the opinion, the consideration to
      be paid by Vodafone to AirTouch stockholders is fair to Vodafone from a
      financial point of view;
 
    - The fact that the chief executive and the financial director of Vodafone
      were expected to be the chief executive and the financial director,
      respectively, of the combined company and that other executive directors
      on the Vodafone board were expected to serve as chief executive officers
      of significant regions of the combined company's operations;
 
                                       35
<PAGE>
    - The fact that the current chairman and chief executive officer of
      AirTouch, Sam Ginn, was expected to be the non-executive chairman of the
      combined company, the current president and chief operating officer of
      AirTouch, Arun Sarin, was expected to be the regional chief executive
      officer for the combined company's U.S./Asia Pacific region and the
      current executive vice president and chief financial officer of AirTouch,
      Mohan Gyani, was expected to be the head of corporate strategy for the
      combined company;
 
    - The board's view that Vodafone should be the acquiror in any merger
      transaction and that Vodafone should retain its listing on the London
      Stock Exchange;
 
    - The expectation that Vodafone shareholders will hold over 50% of the total
      issued share capital of the combined company; and
 
    - The board's view that the merger represents the best opportunity to
      implement Vodafone's strategy of concentrating on the provision of mobile
      telecommunications services worldwide, increasing shareholdings in
      associated companies, bidding for new licenses and making acquisitions,
      and that its ability to implement its strategy will be further enhanced
      through a combination with AirTouch.
 
    The Vodafone board also considered the following potentially negative
factors:
 
    - The board's concern that AirTouch does not have a national U.S. footprint,
      the slower rate of growth in customer numbers in the U.S. and the absence
      of billing on a "calling party pays" basis in the U.S. may provide
      difficulties in Vodafone's ability to realize the full potential of
      entering the U.S. market;
 
    - The potential problems inherent in effecting a transnational combination
      of two organizations, each successful in its own right, and integrating
      their operations which may divert attention from the ongoing business of
      the combined company;
 
    - The board's view that it was uncertain that senior members of AirTouch
      management, who in the board's view were primarily responsible for the
      success of AirTouch to date, would remain with the combined company after
      the merger;
 
    - The overlap of assets in Germany and the fact that it may not be possible
      to maintain both Vodafone's and AirTouch's interests in German ventures
      after the merger;
 
    - The increased borrowings required to finance the merger and to fund the
      combined company after the merger would adversely affect the company's
      credit rating, thereby increasing the cost of borrowing to Vodafone
      AirTouch; and
 
    - The fact that under U.K. GAAP Vodafone will have to account for the merger
      as an acquisition rather than as a merger, which, as a consequence, will
      result in a goodwill amortization charge of approximately $3.4 billion per
      year for a number of years after the merger, thereby reducing the reported
      consolidated profit of Vodafone AirTouch.
 
    The foregoing discussion of the factors considered by the board of directors
of Vodafone is not intended to be exhaustive but includes the material factors
considered by the Vodafone board. In view of the wide variety of factors
considered by the Vodafone board in connection with its evaluation of the merger
and the complexity of these matters, the Vodafone board did not consider it
practical, and did not attempt, to quantify, rank or otherwise assign relative
weights to the specific factors it considered in reaching its decision. The
Vodafone board conducted a discussion of the factors described above, including
asking questions of Vodafone's management and Vodafone's legal, financial and
accounting advisors, and the Vodafone board reached unanimous consensus that the
merger was in the best interests of Vodafone and the Vodafone shareholders. The
Vodafone board relied on, among other things, the experience and expertise of
its financial advisor for certain quantitative analysis of the
 
                                       36

financial terms of the merger. In considering the factors described above,
individual members of the Vodafone board may have given different weight to
different factors. See "--Opinions of Financial Advisors--Opinion of Vodafone's
Financial Advisor."
 
OPINIONS OF FINANCIAL ADVISORS
 
OPINION OF AIRTOUCH'S FINANCIAL ADVISOR
 
    Under a letter agreement dated as of January 3, 1999, AirTouch engaged
Morgan Stanley to provide financial advisory services. The AirTouch board
selected Morgan Stanley to act as its financial advisor for the merger based on
Morgan Stanley's qualifications, expertise and reputation, as well as its
knowledge of the business and affairs of AirTouch. On January 15, 1999, Morgan
Stanley delivered its oral opinion to the AirTouch board that, as of that date,
the consideration to be received in the merger by AirTouch stockholders was fair
from a financial point of view to AirTouch stockholders. Morgan Stanley later
confirmed its oral opinion by delivery of its written opinion dated January 15,
1999, which stated the considerations and assumptions upon which Morgan
Stanley's opinion was based.
 
    THE FULL TEXT OF THE OPINION DATED JANUARY 15, 1999, WHICH SETS FORTH
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE
SCOPE OF THE REVIEW UNDERTAKEN BY MORGAN STANLEY IN RENDERING ITS OPINION, IS
ATTACHED AS APPENDIX B TO THIS PROXY STATEMENT/ PROSPECTUS. MORGAN STANLEY'S
WRITTEN OPINION IS DIRECTED TO THE AIRTOUCH BOARD AND ONLY ADDRESSES THE
FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW AS OF THE
DATE OF THE OPINION. MORGAN STANLEY'S WRITTEN OPINION DOES NOT ADDRESS ANY OTHER
ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY AIRTOUCH
STOCKHOLDER AS TO HOW TO VOTE AT THE AIRTOUCH SPECIAL MEETING. THE FOLLOWING IS
ONLY A SUMMARY OF THE MORGAN STANLEY OPINION. AIRTOUCH STOCKHOLDERS ARE URGED TO
READ THE ENTIRE OPINION.
 
    In arriving at Morgan Stanley's opinion, Morgan Stanley, among other things:
 
    - reviewed publicly available financial statements and other information of
      AirTouch and Vodafone;
 
    - reviewed and discussed internal financial statements and financial and
      operating data concerning AirTouch and Vodafone prepared by the respective
      managements of both companies;
 
    - analyzed financial projections for AirTouch and Vodafone contained in
      securities analysts' research reports that the respective managements of
      both companies recommended for review;
 
    - discussed the past and current operations and financial conditions and the
      prospects of AirTouch and Vodafone, including information relating to
      strategic, financial and operational benefits anticipated from the merger,
      with the respective managements of both companies;
 
    - analyzed the estimated pro forma impact of the merger on Vodafone's
      earnings per share, cash flow, consolidated capitalization and financial
      ratios;
 
    - reviewed the reported prices and trading activity for AirTouch common
      stock and Vodafone ordinary shares and Vodafone ADSs;
 
    - reviewed and discussed with senior executives of each of AirTouch and
      Vodafone the strategic rationale for, and regulatory issues associated
      with, the merger;
 
    - compared the financial performance of AirTouch and Vodafone and the prices
      and trading activity of AirTouch common stock and Vodafone ordinary shares
      and Vodafone ADSs with that of other publicly traded companies and their
      securities;
 
    - reviewed the financial terms, to the extent publicly available, of
      comparable transactions;
 
                                       37
<PAGE>
    - participated in discussions and negotiations among representatives of
      AirTouch and Vodafone and their respective financial, legal and accounting
      advisors;
 
    - reviewed the merger agreement and related documents; and
 
    - performed analyses and considered factors that Morgan Stanley deemed
      appropriate.
 
    Morgan Stanley assumed and relied upon, without independent verification,
the accuracy and completeness of all of the information reviewed by it. In
relying on the internal financial statements and financial and operating data
and discussions relating to the strategic, financial and operational benefits
anticipated from the merger, Morgan Stanley assumed that the internal financial
statements and financial and operating data of Vodafone and AirTouch were
reasonably prepared based on the best currently available estimates and good
faith judgments of the future competitive, operating and regulatory environments
and related financial performance of AirTouch and Vodafone. In relying on the
financial projections for Vodafone included in the securities analysts' research
reports reviewed by Morgan Stanley, Morgan Stanley assumed that the
recommendation of these reports to it by management of Vodafone indicated their
belief that these reports were reasonably prepared on the bases included in the
prior sentence.
 
    Morgan Stanley relied on the financial projections for AirTouch included in
the research reports reviewed by Morgan Stanley based on its own independent
evaluation of these reports and indications by management of AirTouch that the
analyses contained in these reports were reasonably comprehensive and detailed
and were based on assumptions about the trends influencing AirTouch's financial
results that were generally consistent with those of AirTouch's management.
 
    Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities of AirTouch or Vodafone, nor did anyone furnish Morgan
Stanley with any such appraisals. Morgan Stanley's opinion was necessarily based
on economic, market and other conditions in effect on the date of the opinion as
well as the information made available to it at that time.
 
    Morgan Stanley also assumed, with AirTouch's consent, that the merger would
be completed according to the terms of the merger agreement, without waiver of
any condition contained in that agreement, and the merger will be treated as a
tax-free reorganization and/or exchange, each under the U.S. tax code. In
addition, Morgan Stanley assumed that obtaining all necessary regulatory
approvals for the merger will not adversely affect AirTouch, Vodafone or the
contemplated benefits expected to be derived in the merger.
 
    Morgan Stanley was not authorized to solicit, and did not solicit, interest
from any party regarding the acquisition of AirTouch or any of its assets,
although Morgan Stanley participated in discussions with Vodafone and Bell
Atlantic.
 
    The following is a brief summary of the material financial analyses
performed by Morgan Stanley in preparing its opinion. Morgan Stanley used
financial estimates for AirTouch and Vodafone that were based on estimates
published by securities research analysts in the investment community in
performing some of its analyses.
 
    HISTORICAL PUBLIC MARKET TRADING VALUE.  Morgan Stanley reviewed the recent
stock price performance of AirTouch based on an analysis of the historical
closing prices and trading volumes from
 
                                       38

    COMPARATIVE STOCK PRICE PERFORMANCE.  As part of its analysis, Morgan
Stanley reviewed the recent stock price performance of AirTouch and Vodafone and
compared this performance with that of a group of the following five domestic
cellular companies and five international cellular companies:

    Morgan Stanley also compared the closing market price of AirTouch common
stock on January 13, 1998 and January 13, 1999 to the average of the closing
market prices of AirTouch common stock between December 1, 1998, and December
11, 1998, which Morgan Stanley concluded was a period during which speculation
regarding a potential business combination involving AirTouch did not materially
affect the market price of AirTouch common stock. The following table reflects
the results of this exercise and indicates that between the first half of the
month of December 1998 and January 13, 1999, the closing market price of
AirTouch common stock appreciated 32.9%.

    SECURITIES RESEARCH ANALYSTS' FUTURE PRICE TARGETS.  Morgan Stanley reviewed
and analyzed future public market trading price targets for AirTouch common
stock and Vodafone ordinary shares prepared and published by securities research
analysts during the period from October 7, 1998 to January 5, 1999, for
AirTouch, and from August 10, 1998 to December 9, 1998, for Vodafone. These
targets reflected each analyst's estimate of the future public market trading
price of AirTouch common stock and Vodafone ordinary shares at the end of the
particular time period considered for each estimate. The future private market
value targets for AirTouch common stock were reviewed by Morgan Stanley
 
                                       39
<PAGE>
to assess the range of values that the community of securities research analysts
covering AirTouch expected in a change of control transaction. Using a discount
rate of 12.6% for AirTouch and 11.7% for Vodafone, Morgan Stanley discounted
these estimates to January 13, 1999, to arrive at a range of present values of
these targets as set forth below:

    Morgan Stanley noted that the public market trading price and private market
value targets published by the securities research analysts do not reflect
current market trading prices and private market value targets for AirTouch
common stock or Vodafone ordinary shares or Vodafone ADSs and that these
estimates are subject to uncertainties, including the future financial
performance of AirTouch and Vodafone and future financial market conditions.
 
    PEER GROUP COMPARISON.  Morgan Stanley compared financial information of
AirTouch and Vodafone with corresponding financial information for the five
domestic cellular companies and the five international cellular companies.
 
    Morgan Stanley analyzed, among other things, the current aggregate value,
i.e., equity value adjusted for capital structure, of each company expressed as
a multiple of earnings before interest, taxes, and depreciation and amortization
expense adjusted to reflect the relative weight of AirTouch's ownership
interests in its domestic and international cellular systems, and the ratio of
the multiple of current aggregate value to estimated EBITDA in the calendar year
1999 to the estimated, long-term EBITDA growth rate. As of January 13, 1999, and
based on estimates of EBITDA and long-term EBITDA growth rates taken from
selected securities research analysts, the statistics derived from this analysis
are set forth below:

</TABLE>
 
    As stated above, the closing market price of AirTouch common stock on
January 13, 1999, was 32.9% higher than the average daily closing price between
December 1 and December 11, 1998. As a result, Morgan Stanley calculated the
financial multiples and ratios for AirTouch based on this average price which
indicated that, based on this price, AirTouch common stock traded at a multiple
of 10.2x estimated EBITDA for the calendar year 1999, representing a multiple of
0.8x its estimated, long-term EBITDA growth rate.
 
    No company used in the peer group comparison is identical to AirTouch or
Vodafone. In evaluating the peer group companies, Morgan Stanley made judgments
and assumptions with regard to industry performance, business, economic, market
and financial conditions and other matters, many of which are beyond the control
of AirTouch and Vodafone, e.g., the impact of competition on AirTouch or
Vodafone and the industry, industry growth and the absence of any material
adverse change in the financial condition and prospects of AirTouch or Vodafone
or the industry or in the financial markets.
 
    ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS.  As part of its analysis,
Morgan Stanley reviewed the following twelve transactions involving domestic
cellular companies since 1996:
 
                                       40
<PAGE>
    - April 1996--360 DEG. Communications Company/Independent Cellular Network
      Partners
 
    - April 1996--AirTouch Communications, Inc./Cellular Communications, Inc.
 
    - May 1997--The Blackstone Group L.P./CommNet Cellular Inc.
 
    - May 1997--Price Communications Corporation/Palmer Wireless, Inc.
 
    - January 1998--AirTouch Communications, Inc./U S WEST NewVector
 
    - February 1998--Rural Cellular Corporation/Atlantic Cellular Company, L.P.
 
    - March 1998--American Cellular Corp./PriCellular Corporation
 
    - March 1998--ALLTEL Corporation/360 DEG. Communications Company
 
    - July 1998--Welsh, Carson, Anderson & Stowe/Centennial Cellular Corp.
 
    - July 1998--Dobson Communications Corporation/Sygnet Wireless, Inc.
 
    - October 1998--AT&T Corp./Vanguard Cellular Systems Inc.
 
    - October 1998--AT&T Wireless Services Inc./BellSouth Cellular Corp.
 
    For each of these, Morgan Stanley reviewed the prices paid and calculated
the multiples of one year forward EBITDA. This analysis indicated multiples
ranging from 9.1x to 10.9x one year forward EBITDA for these transactions, with
a median multiple of 10.1x. Morgan Stanley determined that, because there were
no relevant publicly disclosed transactions involving international cellular
companies or assets which were directly comparable to AirTouch's international
cellular business, this type of analysis did not constitute an appropriate
valuation methodology for AirTouch's international cellular business.
 
    No transaction used in the analysis of selected precedent transactions is
identical to the merger. In evaluating these transactions, Morgan Stanley made
judgments and assumptions with regard to industry performance, business,
economic, market and financial conditions and other matters, many of which are
beyond the control of AirTouch and Vodafone, e.g., the impact of competition on
AirTouch or Vodafone and the industry, industry growth and the absence of any
material adverse change in the financial condition and prospects of AirTouch or
Vodafone or the industry or in the financial markets.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Morgan Stanley performed discounted cash
flow analyses of AirTouch's domestic and international cellular businesses. A
discounted cash flow analysis involves an analysis of the present value of
projected cash flows and a terminal value using discount rates and terminal year
EBITDA multiples as indicated below. Morgan Stanley analyzed AirTouch's domestic
cellular business using a forecast for the period beginning January 1, 1999, and
ending December 31, 2002, based on estimates published by securities research
analysts. Morgan Stanley estimated AirTouch's domestic cellular discounted cash
flow value by using discount rates ranging from 10% to 11% and terminal
multiples of estimated 2002 EBITDA ranging from 9.5x to 10.5x. This analysis
yielded a range of values for AirTouch's domestic cellular business of
approximately $17 billion to $19 billion. Morgan Stanley analyzed AirTouch's
international cellular business using a forecast for the period beginning
January 1, 1999, and ending December 31, 2005, based on estimates published by
securities research analysts. Morgan Stanley estimated AirTouch's international
cellular discounted cash flow value by using discount rates ranging from 10% to
11% and terminal multiples of estimated 2005 EBITDA ranging from 11.0x to 13.0x.
This analysis yielded a range of values for AirTouch's international cellular
business of approximately $25 billion to $29 billion. The discounted cash flow
values of AirTouch's domestic and international cellular businesses implied a
range of values for AirTouch common stock of $65 to $75 per share. In addition,
Morgan Stanley performed sensitivity analyses on assumptions underlying the
international cellular forecast. Specifically, Morgan Stanley
 
                                       41
<PAGE>
varied the assumptions regarding monthly churn rate, average revenue per user
decline and acquisition costs per gross addition over the projection period.
These changes yielded additional value for AirTouch's international cellular
business of $5 billion to $6 billion using discount rates ranging from 10% to
11% and terminal multiples of estimated 2005 EBITDA ranging from 11.0x to 13.0x.
This sensitivity case implied a range of values for the AirTouch common stock of
$73 to $84 per share.
 
    Morgan Stanley calculated the range of implied 2002 terminal EBITDA
multiples by employing a discounted cash flow analysis that included a forecast
based on estimates published by securities analysts and by assuming a range of
Vodafone ADS prices of $130 to $200. Morgan Stanley then compared these
multiples to the growth in EBITDA between 2002 and 2003. These calculations
implied that in order to arrive at Vodafone ADS prices of $130 and $200, the
2002 terminal multiple would need to be equal to the 2002 to 2003 growth in
EBITDA and be at a 57% premium to the 2002 to 2003 EBITDA growth rate,
respectively. Morgan Stanley observed that the relationship of terminal EBITDA
multiple to growth in EBITDA, I.E., 100% to 157%, suggested by the discounted
cash flow analysis of Vodafone was consistent with similar statistics analyzed
in the peer group comparison of the international cellular companies.
 
    RELATIVE CONTRIBUTION ANALYSIS.  Morgan Stanley compared the pro forma
contribution of each of AirTouch and Vodafone, based on historical information
and securities research analyst estimates, to the resultant combined company
assuming completion of the merger. The results of this analysis are set forth
below:

    Morgan Stanley then adjusted these statistics to reflect each company's
respective capital structure and then compared them to the pro forma ownership
by AirTouch stockholders, on a diluted basis, of the common stock of the
combined company, implied by the merger consideration, of approximately 50%.
Morgan Stanley also compared these adjusted statistics to the pro forma
ownership by AirTouch stockholders, on a diluted basis, of the common stock of
the combined company, implied by the effective exchange ratio suggested by the
merger consideration, i.e., the exchange ratio plus the fraction that results
from the division of the amount of the cash consideration by the Vodafone ADS
price of $170.50 as of January 13, 1999, of approximately 53.0%.
 
    EXCHANGE RATIO ANALYSIS.  Morgan Stanley compared the effective exchange
ratio to the ratio of the closing market prices of AirTouch common stock and
Vodafone ADSs on January 13, 1999. Morgan Stanley also compared this ratio to
selected average historical ratios of the closing market prices of AirTouch
common stock to Vodafone ADSs over various periods ending December 11, 1998,
which date Morgan Stanley concluded was appropriate for this analysis. Morgan
Stanley then calculated the
 
                                       42

premiums represented by the effective exchange ratio over these ratios. The

    ANALYSIS OF PREMIUMS PAID IN SELECTED PRECEDENT LARGE TRANSACTIONS.  Morgan
Stanley reviewed nine selected acquisition transactions with values of $20
billion or greater, and analyzed the premiums paid over prevailing market prices
and exchange ratios in these transactions. Set forth below is a comparison of
the high, low and median premiums at 30 days prior to announcement of the
subject transaction and at one day prior to announcement.

Note: (1) Measured from 30 days prior to announcement of subject precedent large
transaction.
 
    Morgan Stanley observed that the premiums to the market price of AirTouch
common stock 30 days prior to, and on December 11, 1998 implied by the merger
consideration and a closing price for Vodafone ADSs of $170.50 as of January 13,
1999 were 74.7% and 62.1%, respectively. Morgan Stanley also observed that the
premiums to the one year average market exchange ratio of the prices of AirTouch
common stock and Vodafone ADSs and the trailing three month average market
exchange ratio measured from 30 days prior to December 11, 1998, implied by the
effective exchange ratio, were 18.1% and 25.9%, respectively.
 
    PRO FORMA ANALYSIS OF THE MERGER.  Morgan Stanley analyzed the pro forma
impact of the merger on Vodafone's earnings per share for the calendar years
1999 and 2000, as estimated by securities research analysts. Morgan Stanley
observed that, assuming the merger was treated as an acquisition for accounting
purposes under U.K. GAAP, the merger would result in earnings per share dilution
for Vodafone shareholders for each of the calendar years 1999 and 2000,
respectively. Morgan Stanley also noted that the pro forma analysis suggested
that the merger would result in a more leveraged capital structure for Vodafone.

    Morgan Stanley performed a variety of financial and comparative analyses
solely for purposes of providing its opinion to the AirTouch board as to the
fairness from a financial point of view to the AirTouch stockholders of the
merger consideration. While the foregoing summary describes the analyses and
factors reviewed by Morgan Stanley for its opinion, it is not intended to be a
complete description of all the analyses performed by Morgan Stanley in arriving
at its opinion. The preparation of a fairness opinion is a complex process and
is not necessarily susceptible to partial analysis or summary description.
 
    In arriving at its opinion, Morgan Stanley considered the results of all of
its analyses as a whole and did not attribute any particular weight to any
analysis or factor considered by it. Furthermore, selecting any portion of its
analyses, without considering all analyses, would create an incomplete view of
the process underlying its opinion.
 
    In addition, Morgan Stanley may have given various analyses and factors more
or less weight than other analyses and factors, and may have deemed various
assumptions more or less probable than other assumptions, so that the ranges of
valuations resulting from any particular analysis described above should not be
taken to be Morgan Stanley's view of the actual value of AirTouch or Vodafone.
 
    In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters, many of which are beyond the control of AirTouch or Vodafone. Any
estimates contained herein are not necessarily indicative of future results or
actual values, which may be significantly more or less favorable than those
suggested by the estimates. Morgan Stanley performed the analyses solely as part
of Morgan Stanley's analysis of the fairness of the merger consideration from a
financial point of view to the AirTouch stockholders and were conducted in
connection with the delivery of its opinion. The analyses are not intended to be
appraisals or to reflect the prices at which AirTouch or Vodafone might actually
be sold or the price at which their securities may trade.
 
    The merger consideration was determined through arm's-length negotiations
between AirTouch and Vodafone and was approved by the AirTouch board. Morgan
Stanley did not recommend any specific merger consideration to AirTouch or that
any specific merger consideration constituted the only appropriate merger
consideration for the merger. Morgan Stanley's opinion to the AirTouch board was
one of many factors taken into consideration by the AirTouch board in making its
determination to approve the merger. Consequently, the Morgan Stanley analyses
described above should not be viewed as determinative of the opinion of the
AirTouch board with respect to the value of AirTouch or whether the AirTouch
board would have been willing to agree to different merger consideration.
 
    The AirTouch board retained Morgan Stanley based upon Morgan Stanley's
qualifications, experience and expertise. Morgan Stanley is an internationally
recognized investment banking and advisory firm. Morgan Stanley, as part of its
investment banking business, is continuously engaged in the valuation of
businesses and securities in connection with mergers and acquisitions,
negotiated underwritings, competitive biddings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. In the ordinary course of Morgan Stanley's trading,
brokerage and financing activities, Morgan Stanley or its affiliates may at any
time hold long or short positions, may trade, make a market or otherwise effect
transactions, for its own account or for the accounts of customers, in the
securities of AirTouch or Vodafone. In the past, Morgan Stanley and its
affiliates have provided financial advisory and financing services for AirTouch
and Bell Atlantic and have received fees for the rendering of these services.
 
    In addition to acting as AirTouch's financial advisor in connection with the
merger, Morgan Stanley has, in the past several years, advised AirTouch on other
business combination transactions as well as acted as lead underwriter in
securities offerings. The aggregate fees paid by AirTouch to Morgan Stanley for
services rendered, including fees payable in connection with the merger, total
$71 million. AirTouch has agreed to indemnify Morgan Stanley and its affiliates,
their respective directors, officers, agents and employees and each person, if
any, controlling Morgan Stanley or any of its
 
                                       44

affiliates against certain liabilities and expenses, including the fees of its
legal counsel and certain liabilities under the federal securities laws, arising
out of Morgan Stanley's engagement and the transactions in connection therewith.
 
OPINION OF VODAFONE'S FINANCIAL ADVISOR
 
    In March 1998, Vodafone asked Goldman Sachs International to act as its
financial advisor in connection with a possible combination with AirTouch. At
the January 14, 1999 meeting of the Vodafone board, Goldman Sachs International
gave the Vodafone board an oral opinion, subsequently confirmed in writing,
that, as of the date of the opinion and based upon and subject to the
considerations set forth in its opinion, the consideration to be paid by
Vodafone for each share of AirTouch common stock in the merger is fair from a
financial point of view to Vodafone.
 
    APPENDIX C CONTAINS THE FULL TEXT OF THE GOLDMAN SACHS INTERNATIONAL
OPINION, WHICH SETS FORTH THE ASSUMPTIONS GOLDMAN SACHS INTERNATIONAL MADE,
PROCEDURES IT FOLLOWED, MATTERS IT CONSIDERED AND LIMITATIONS ON THE SCOPE OF
ITS REVIEW AND WHICH IS INCORPORATED BY REFERENCE WITH GOLDMAN SACHS
INTERNATIONAL'S CONSENT. THE GOLDMAN SACHS INTERNATIONAL OPINION ADDRESSES ONLY
THE FAIRNESS OF THE CONSIDERATION TO BE PAID BY VODAFONE FOR EACH SHARE OF
AIRTOUCH COMMON STOCK IN THE MERGER FROM A FINANCIAL POINT OF VIEW ON JANUARY
15, 1999, AND DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER. IT IS NOT A
RECOMMENDATION AS TO HOW ANY SHAREHOLDER OF VODAFONE SHOULD VOTE ON THE MERGER.
THE FOLLOWING IS ONLY A SUMMARY OF THE OPINION. YOU SHOULD READ THE ENTIRE
OPINION CAREFULLY.
 
    In giving its opinion, Goldman Sachs International reviewed, among other
things:
 
    (1) the merger agreement;
 
    (2) publicly available information including:
 
       (a) the audited financial statements of Vodafone for the five years ended
           March 31, 1998,
 
       (b) the audited financial statements of AirTouch for the five years ended
           December 31, 1997,
 
       (c) the unaudited pro forma financial statements of AirTouch for the year
           ended December 31, 1997, adjusted to reflect the acquisition of the
           U.S. wireless business of U S WEST,
 
       (d) the unaudited interim reports of Vodafone for the periods ended
           September 30, 1997 and 1998,
 
       (e) the unaudited quarterly reports of AirTouch on Form 10-Q for the
           three consecutive quarterly periods ended September 30, 1997 and 1998
           and
 
       (f) certain other communications from Vodafone and AirTouch to their
           shareholders; and
 
    (3) internal financial analyses of, and forecasts for, Vodafone and AirTouch
       prepared by management of Vodafone, including an estimate of expected
       cost savings and other synergies.
 
    Goldman Sachs International also participated in discussions with members of
senior management of Vodafone regarding the strategic rationale for, and the
potential benefits of, the merger and the past and current business operations
of Vodafone and AirTouch, the financial condition and the view of Vodafone's
management of the future prospects of Vodafone and AirTouch, the view of
Vodafone's management of the effects of the merger on the financial condition
and future prospects of Vodafone, AirTouch and the combined Vodafone AirTouch
business, and other matters Goldman Sachs International believed necessary or
appropriate to its inquiry. Goldman Sachs International participated in a
discussion of financial due diligence matters that the senior management of
Vodafone and AirTouch held on January 11, 1999. Goldman Sachs International also
reviewed financial studies and analyses and considered other information that it
deemed appropriate for giving its opinion.
 
                                       45
<PAGE>
    In giving its opinion, Goldman Sachs International relied upon and assumed
the accuracy and completeness of all information reviewed by it. Goldman Sachs
International has not verified the accuracy or completeness of that information,
and it has not evaluated or appraised any assets or liabilities of Vodafone or
AirTouch or any of their respective subsidiaries, nor has Vodafone or AirTouch
or any other person given any valuations or appraisals to Goldman Sachs
International.
 
    Goldman Sachs International assumed that the financial analyses and
forecasts provided to it by Vodafone were reasonably prepared based on
assumptions reflecting the best currently available estimates and judgments of
Vodafone's management as to the expected future financial and operating
performance of Vodafone and AirTouch. Goldman Sachs International also assumed
that the merger would have the tax and accounting consequences described in
discussions with representatives and advisors of Vodafone. In particular,
Goldman Sachs International assumed that Vodafone would account for the merger
as an acquisition under U.K. GAAP and as a purchase under U.S. GAAP. Goldman
Sachs International relied as to all legal matters relevant to its opinion on
the advice of counsel.
 
    The following is a brief summary of the material analyses Goldman Sachs
International performed and reviewed with the Vodafone board when giving its
opinion.
 
    1. COMPARABLE ENTERPRISE VALUE/EBITDA ANALYSIS
 
    Goldman Sachs International reviewed and compared the enterprise value to
EBITDA multiples of Vodafone and AirTouch to those of a number of other European
and U.S. mobile communications companies. The enterprise value/EBITDA multiple
is a commonly used measure of value, and a comparison of this multiple for
different companies can be used to gauge relative value.
 
    Goldman Sachs International calculated enterprise value on a proportionate
basis, including proportionate net debt, and EBITDA on a proportionate basis. In
addition, it based the enterprise value of each company on the aggregate equity
market capitalization of that company, calculated using the closing share price
of the company on January 13, 1999 multiplied by its fully diluted number of
shares based on the most recent publicly available information and taking into
account the spread value of options, plus net debt from the most recent publicly
available balance sheet information of the company. The source for the EBITDA of
each company was research analyst forecasts, adjusted to the years ending
December 31, 1998 and 1999.
 
    This analysis indicated the following enterprise value/EBITDA multiples (1):

    2. CONTRIBUTION ANALYSIS
 
    Goldman Sachs International analyzed the expected contribution of Vodafone
and AirTouch to a combined Vodafone AirTouch entity.
 
    Under the terms of the merger, holders of AirTouch common stock will receive
0.5 of a Vodafone ADS plus $9.00 in cash for each share of AirTouch common
stock. Based on the closing price for Vodafone ADSs on January 13, 1999, the
consideration to be paid for AirTouch implied that AirTouch had an aggregate
equity value on a fully diluted basis of $58.7 billion, and that Vodafone had an
aggregate equity value on a fully diluted basis of $53.0 billion. Under this
analysis, current Vodafone shareholders will have an approximate 47.5% economic
interest in the combined Vodafone AirTouch entity on a fully diluted basis.
After adjusting for the cash element of the consideration, Vodafone shareholders
will hold over 50% of the common equity of the combined Vodafone AirTouch entity
on a fully diluted basis.
 
    Goldman Sachs International reviewed and analyzed the then most current
research analyst forecasts for proportionate cellular subscribers, proportionate
revenues and proportionate EBITDA of Vodafone and AirTouch, adjusted, in the
case of AirTouch, to the years ending March 31, 1999 and 2000. For the year
ending March 31, 1999, Vodafone was forecast to contribute approximately 37% of
the proportionate cellular subscribers, approximately 42% of the proportionate
revenues and approximately 40% of the proportionate EBITDA of a combined
Vodafone AirTouch entity. For the year ending March 31, 2000, Vodafone was
forecast to contribute approximately 37% of the proportionate cellular
subscribers, approximately 42% of the proportionate revenues and approximately
41% of the proportionate EBITDA of a combined Vodafone AirTouch entity. In
addition, on the basis of the same analyst research, Vodafone was forecast to
have a compound annual EBITDA growth rate of approximately 27% for the
three-year period ending March 31, 2002, and AirTouch was forecast to have a
compound annual EBITDA growth rate of approximately 24% for the three-year
period adjusted to March 31, 2002.
 
    3. SHARING OF FUTURE BENEFITS OF THE MERGER
 
    Goldman Sachs International noted that the merger was expected to result in
significant future benefits to the two companies. Goldman Sachs International
pointed out that the Vodafone management expected the merger to result in
significant cost and revenue synergies over the next several years. Based on its
preliminary evaluation, Vodafone management expected the merger to deliver
after-tax net cash flow savings of approximately $330 million per year by the
year ending March 31, 2002. The net present value of these savings was
approximately $3.5 billion based on a discount rate of 9%.
 
    4. ANALYSIS OF PURCHASE PRICE
 
    Goldman Sachs International determined that the price Vodafone would pay in
the merger per share of AirTouch common stock would be $94.25, based on the
terms of the merger agreement and a closing price per Vodafone ADS of $170.50 on
January 13, 1999. This price represented a 22% premium over the $77.25 closing
price per share of AirTouch common stock on January 13, 1999 and a

<PAGE>
36% premium over the $69.38 closing price per share of AirTouch common stock on
December 30, 1998.
 
    Goldman Sachs International also calculated the fully diluted levered
consideration taking into account the spread value of options, as a multiple of
proportionate EBITDA of AirTouch based on current analyst research estimates. It
calculated these multiples using the consideration specified in the merger
agreement of 0.5 of a Vodafone ADS and $9.00 in cash per share of AirTouch
common stock and the closing price for Vodafone ADSs on January 13, 1999.
 
    Goldman Sachs International compared these multiples with the equivalent
multiples for Vodafone.
 
    The following table sets forth, for the periods indicated, the fully diluted
levered consideration as a multiple of proportionate EBITDA of AirTouch and
Vodafone:

     business of U S WEST had taken place at the beginning of the period.
 
    In addition, for the period ending December 31, 1999, Goldman Sachs
International compared the AirTouch enterprise value/EBITDA multiples with
enterprise value/EBITDA multiples set forth above under the comparable
enterprise value/EBITDA analysis for selected European mobile communications
companies.
 
    5. VODAFONE PRO FORMA MERGER ANALYSIS
 
    Goldman Sachs International also analyzed the expected effects of the merger
on Vodafone's future financial and operating performance. Goldman Sachs
International prepared a pro forma analysis of the financial impact of the
merger on the financial performance of Vodafone following the merger, using
estimates prepared by the Vodafone management for proportionate EBITDA, earnings
per share before goodwill amortization and earnings per share after goodwill
amortization of Vodafone for the years ending March 31, 2000, 2001 and 2002, and
estimates based on current analyst research forecasts, adjusted to reflect the
views of Vodafone management, for proportionate EBITDA, earnings per share
before goodwill amortization and earnings per share after goodwill amortization
of AirTouch for the years ending December 31, 1999, 2000 and 2001. Goldman Sachs
International adjusted the estimates for AirTouch to a March 31 year end and
converted dollar amounts into sterling at a fixed exchange rate of $1.65 = L1.
 
    Goldman Sachs International also assumed, based on Vodafone management
estimates, after-tax net cash flow savings from synergies of $330 million by the
year ending March 31, 2002 and phased in the synergies, over the preceding
periods. Goldman Sachs International compared the proportionate EBITDA, earnings
per share before goodwill amortization and earnings per share after goodwill
amortization of Vodafone on a standalone basis with those of the combined
Vodafone AirTouch entity on a pro forma basis. Goldman Sachs International
performed this analysis based on a closing price of $170.50 per Vodafone ADS and
$77.25 per share of AirTouch common stock on January 13, 1999. The analysis
showed that, on an equivalent share basis and excluding any special
restructuring charges, the
 
                                       48
<PAGE>
merger would be accretive to holders of Vodafone ordinary shares on a
proportionate EBITDA and earnings per share before goodwill amortization basis,
and dilutive to holders of Vodafone ordinary shares on an earnings per share
basis, in each of the years considered.
 
    The preparation of a fairness opinion is a complex process and is not
susceptible to partial analysis or summary description. In arriving at its
opinion, Goldman Sachs International considered the results of all of its
analyses as a whole. Furthermore, Goldman Sachs International believes that
selecting any portion of its analyses, without considering all analyses, could
create an incomplete view of the process underlying its opinion. No company or
transaction Goldman Sachs International used in the analysis referred to above
is identical to Vodafone, AirTouch or the merger. In addition, Goldman Sachs
International may have given various analyses and factors more or less weight
than other analyses and factors and may have deemed various assumptions more or
less probable than other assumptions, and the ranges of valuation resulting from
any particular analysis described above should not be taken as Goldman Sachs
International's view of the actual value of Vodafone or AirTouch. In performing
these analyses, Goldman Sachs International made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters, many of which are beyond the control of Vodafone or AirTouch. Any
estimates contained in Goldman Sachs International's analyses are not
necessarily indicative of future results or actual values, which may be
significantly more or less favorable than those suggested by the estimates.
Goldman Sachs International performed the analyses solely as part of its
analysis of the fairness of the consideration to be paid by Vodafone for each
share of AirTouch common stock in the merger from a financial point of view to
Vodafone. Goldman Sachs International prepared these analyses in connection with
the delivery of its opinion to the Vodafone board. Neither the analyses nor the
Goldman Sachs International opinion is an appraisal. In addition, Goldman Sachs
International has expressed no opinion as to the price at which securities of
Vodafone, AirTouch or Vodafone AirTouch will trade at any time. As described
above, the Goldman Sachs International opinion and presentation to the Vodafone
board was one of the many factors the Vodafone board took into account in making
its determination to approve the merger agreement.
 
    The Vodafone board retained Goldman Sachs International based upon its
qualifications, experience and expertise, including in significant transactions
in the telecommunications and cellular industries. Goldman Sachs International
is an internationally recognized investment banking and advisory firm. As part
of its investment banking and financial advisory business, Goldman Sachs
International is continuously engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. In addition, Goldman Sachs International is a full-service securities
firm engaged in securities trading, brokerage and financing activities. Goldman
Sachs International makes a market in Vodafone ordinary shares. In the ordinary
course of its trading and brokerage activities, Goldman Sachs International or
its affiliates may at any time hold long or short positions, and may trade or
otherwise effect transactions, for its own account or the accounts of customers,
in debt or equity securities or senior loans of Vodafone or AirTouch or their
affiliates.
 
    Pursuant to an engagement letter with Goldman Sachs International, Vodafone
has agreed to pay Goldman Sachs International a customary transaction fee based
on the aggregate agreed value of AirTouch plus an additional fee payable solely
at the discretion of Vodafone. A significant portion of both fees is contingent
upon the closing of the merger. Vodafone has also agreed to reimburse Goldman
Sachs International for its reasonable out-of-pocket expenses, including the
fees and expenses of Goldman Sachs International's attorneys, and to indemnify
Goldman Sachs International against certain liabilities, including liabilities
under the federal securities laws. In the past, Goldman Sachs International and
its affiliates have provided financial advisory services to Vodafone, AirTouch
and its affiliates and have received customary fees for such services. The
aggregate fees paid or payable by Vodafone to Goldman Sachs International for
services rendered during the past two years, including in
 
                                       49
<PAGE>
connection with the merger, total $31.5 million (excluding any future fees
payable at the discretion of Vodafone). During this period, Goldman Sachs
International did not receive any fees from AirTouch.
 
PLANS FOR AIRTOUCH AFTER THE MERGER
 
    Following the merger, AirTouch will be a subsidiary of Vodafone and will
change its name to "Vodafone AirTouch Inc." Vodafone AirTouch will own all of
the outstanding shares of AirTouch common stock and existing holders or their
transferees will continue to own any outstanding shares of the AirTouch Class C
preferred stock, AirTouch Class D preferred stock and AirTouch Class E preferred
stock. As a result of the internal reorganization, holders of each class of
AirTouch preferred stock will have the right to vote together with the AirTouch
common stock on all matters brought before a meeting of stockholders. The
AirTouch Class C preferred stock will vote on the basis of 1.379 votes per share
and the AirTouch Class D preferred stock and AirTouch Class E preferred stock
will each vote on the basis of 12 votes per share. As a result, following the
merger, Vodafone AirTouch is expected to control, through its ownership of all
of the AirTouch common stock, between approximately 94.4% and 96.9% of the
voting power of all outstanding AirTouch capital stock, depending upon the
number of shares of AirTouch Class C preferred stock converted into AirTouch
common stock and the number of AirTouch stock options exercised prior to the
merger.
 
INTERESTS OF MEMBERS OF AIRTOUCH BOARD AND MANAGEMENT IN THE MERGER
 
    In considering the recommendation of the AirTouch board to vote "FOR"
approval and adoption of the merger agreement and the agreement providing for
the internal reorganization, AirTouch stockholders should be aware that a number
of directors and officers of AirTouch have certain interests in the merger that
are different from, or in addition to, the interests of AirTouch stockholders
generally. The AirTouch board recognized those interests and determined that
they neither supported nor detracted from the advisability of the merger or the
internal reorganization to AirTouch or its stockholders.
 
    EMPLOYMENT AGREEMENTS
 
    AirTouch has entered into employment agreements with each of its seven
executive officers:
 
    - Mr. Sam Ginn, chairman of the board and chief executive officer of
      AirTouch,
 
    - Mr. Arun Sarin, president and chief operating officer of AirTouch,
 
    - Mr. Mohan Gyani, executive vice president and chief financial officer of
      AirTouch,
 
    - Mr. Brian Jones, senior vice president of AirTouch,
 
    - Ms. Margaret Gill, senior vice president, legal, external affairs and
      secretary of AirTouch,
 
    - Mr. Craig Farrill, vice president, strategic technology officer of
      AirTouch, and
 
    - Mr. Terry D. Kramer, vice president, human resources and corporate
      services of AirTouch.
 
    Under the terms of the AirTouch employment agreements, each of the first six
executive officers named above may become entitled to receive the following
benefits if his or her employment terminates under certain conditions within
three years after a change in control of AirTouch, which would be deemed to
occur for purposes of the employment agreements upon completion of the merger:
 
    - a cash severance payment equal to the sum of three times base compensation
      in effect on the date of termination, plus 300% of the target award under
      the AirTouch Communications Incentive Plan for the calendar year in which
      the termination occurs,
 
                                       50
<PAGE>
    - all equity incentive awards, including stock options and all awards with
      respect to equity or derivative securities and non-qualified pension plan
      benefits will become fully vested, fully exercisable or fully payable,
 
    - an extension period for incentive awards such that the period beginning on
      the date when the termination of employment is effective and ending on the
      earlier of the first anniversary of termination or on the executive
      officer's death will be counted as employment with AirTouch for purposes
      of determining the expiration date of any incentive awards,
 
    - continued coverage under welfare benefit arrangements for a period of up
      to three years from the date of termination,
 
    - provision of professional financial counseling services for one year
      following termination, and
 
    - if any payments pursuant to the AirTouch employment agreements would be
      subject to any excise tax under Section 4999 of the U.S. tax code,
      AirTouch will provide an additional gross-up payment so that the executive
      officer will retain a net amount equal to the payments he would have
      retained if the excise tax had not applied.
 
    The change in control severance benefits for Mr. Kramer are the same as
those for the other executive officers, except the severance payment multiple
referred to above is reduced to two times base compensation, the severance
percentage referred to above is reduced to 200% of the target award for the
calendar year in which the termination occurs, the continuation period for
welfare benefits is reduced to two years, and there is no extension period for
incentive awards. On February 11, 1999, as contemplated in the merger agreement,
the Compensation and Personnel Committee of the AirTouch board acted to
 
    - waive all caps on amounts payable to Mr. Kramer in the event of a change
      of control, and
 
    - provide an additional gross-up payment if any payments pursuant to the
      AirTouch employment agreement would be subject to any excise tax under
      Section 4999 of the U.S. tax code, so that Mr. Kramer will retain a net
      amount equal to the payments he would have retained if the excise tax had
      not applied, if (1) he remains employed for at least six months after the
      merger closes, or (2) his employment is terminated after the merger unless
      the termination is voluntary or is a constructive discharge.
 
    AirTouch is obligated to provide the change in control severance benefits to
all seven executive officers if:
 
    - the executive officer voluntarily terminates his employment in response to
      a material reduction in salary or benefits, a material change in
      responsibilities, or a requirement to relocate, except for office
      relocations that would not increase the executive officer's one-way
      commute distance by more than 40 miles,
 
    - AirTouch terminates the executive officer's employment for any reason,
      including for cause or disability, or
 
    - in the case of an executive officer other than Mr. Kramer, the executive
      officer voluntarily terminates his employment for any reason during the
      thirteenth full calendar month following a change in control.
 
    The following table sets forth the names, positions and estimated maximum
cash severance payments payable, not including any additional gross-up payment,
under the employment agreements referred to above for the five executive
officers who are expected to receive the greatest benefits under

    STOCK OPTIONS
 
    Upon completion of the merger, all then unvested stock options granted under
AirTouch's 1993 Long-Term Stock Incentive Plan will become fully vested and
fully exercisable. The following table sets forth, with respect to the five
highest compensated executive officers:
 
    - the number of shares of AirTouch common stock subject to unvested stock
      options held by those persons as of April 20, 1999,
 
    - the weighted average exercise price for those AirTouch stock options and
 
    - the estimated aggregate value of those stock options before deduction for
      applicable withholding taxes, assuming that the options are converted into
      options to purchase Vodafone AirTouch ADSs, based on the market price of
      Vodafone ADSs at the close of business on April 20, 1999 of $170.5625,
      determined by subtracting the aggregate exercise price from the total
      value of the shares subject to these stock options.

    SUPPLEMENTAL EXECUTIVE PENSION PLAN
 
    Messrs. Sarin and Farrill participate in the minimum pension component of
AirTouch's Supplemental Executive Pension Plan. This is a retirement benefit
equal to 45% of final average compensation and is payable to the executive
officer if he retires at or after 55 years of age with ten years of service. If
either of Messrs. Sarin and Farrill is terminated under circumstances entitling
him to severance benefits under the employment agreements described above within
three years following a change of control, then the participant will be deemed
to have satisfied all age and service requirements for eligibility to receive a
minimum pension benefit under the Supplemental Executive Pension Plan.
 
    The following table sets forth the present value of the maximum additional
benefits that may accrue for the benefit of the named executive officers upon a
qualifying termination of employment:

    LONG-TERM INCENTIVE PLAN
 
    Each of the executive officers participates in AirTouch's Long-Term
Incentive Plan. This plan is a part of the AirTouch Communications Incentive
Plan. After the close of each 3-year performance period, the plan may pay cash
awards, depending on the attainment of performance targets for the 3-year
period. Each performance period consists of 3 consecutive calendar years. The
performance periods overlap, with a new one beginning each year.
 
    If an executive officer becomes entitled to a severance benefit under his
employment agreement on account of a change of control, the amount of the actual
award payable for each performance period will be equal to the sum of,
 
                                       53
<PAGE>
    (1) with respect to the period before termination of employment, a portion
of the award, calculated on the basis of 100% of the target amount, prorated
based on the participant's period of service from the start of the performance
period to the date of termination and
 
    (2) with respect to the period after termination of employment, a portion of
the award, calculated on the basis of 100% of the target amount, prorated based
on the time between the separation from employment and the end of the
performance period and then multiplied by 50%.
 
    The following table sets forth the estimated cash amounts that would be
payable to the named executive officers based on their target awards for current
performance periods, assuming that their employment terminates on July 1, 1999.

    OTHER AGREEMENTS
 
    Vodafone has entered into an agreement with Mr. Sam Ginn which provides for
his engagement as a non-executive director of Vodafone AirTouch and as chairman
of the board of directors for a two-year term following the merger. The
agreement provides for an annual fee of $375,000, payment of agreed expenses
during the term of the agreement and the provision of perquisites during the
term of the agreement and thereafter. The agreement will take effect only if the
conditions to the merger set out in the merger agreement are satisfied or waived
and Mr. Ginn is elected as a director of Vodafone AirTouch.
 
    DIRECTOR AND OFFICER INDEMNIFICATION AND INSURANCE
 
    In the merger agreement, Vodafone and AirTouch have agreed that after the
merger all rights to indemnification and all limitations on liability existing
under the AirTouch certificate of incorporation and the AirTouch by-laws in
favor of directors and officers of AirTouch, or under an agreement in effect as
of the date of the merger agreement between any director or officer and AirTouch
or its subsidiaries, with respect to actions or omissions by them on or prior to
the merger, will continue in full force and effect. In addition, subject to
those limitations described in the merger agreement, Vodafone AirTouch will, for
six years after the merger, provide directors' and officers' liability insurance
for acts or omissions occurring prior to the merger covering each person
currently covered by AirTouch's directors' and officers' liability insurance on
terms and in amounts no less favorable than those of the policy currently in
effect.
 
    BOARD OF DIRECTORS
 
    As of the date hereof, the board of directors of Vodafone comprises 10
directors. Vodafone and AirTouch have agreed that, upon completion of the
merger, the Vodafone AirTouch board will comprise 14 persons, seven of whom will
be designated by Vodafone of whom three will be non-executive directors and
seven of whom will be designated by AirTouch of whom five will be non-executive
directors. The AirTouch designees are Messrs. Ginn, Sarin, Gyani, Donald G.
Fisher, Paul Hazen, Michael J. Boskin and Charles R. Schwab. See "DIRECTORS AND
MANAGEMENT OF VODAFONE AIRTOUCH FOLLOWING THE MERGER."
 
                                       54
<PAGE>
ACCOUNTING TREATMENT
 
    Vodafone AirTouch will account for the merger as an acquisition under U.K.
GAAP in accordance with Financial Reporting Standard 6, "Acquisitions and
Mergers" and will account for the merger as a purchase for U.S. GAAP purposes in
accordance with APB Opinion No. 16, "Business Combinations."
 
    In each case, the excess of the purchase price over the fair value of the
net assets acquired will be recorded as goodwill and amortized over its
estimated economic life. The merger will result in a goodwill amortization
charge of approximately $3.4 billion per year for a number of years after the
merger, thereby reducing the reported consolidated profit of Vodafone AirTouch
under U.K. GAAP. This goodwill amortization arises as an accounting charge
against profit upon the consolidation of Vodafone and AirTouch but will not
affect Vodafone AirTouch's cash flows, distributable reserves or ability to pay
dividends. Following the merger, Vodafone AirTouch will report earnings per
share before goodwill amortization expense and profit or loss on the disposal of
fixed asset investments, in addition to basic and diluted earnings per share.
For more detail about the amount of goodwill Vodafone AirTouch will have to
record and the way in which such goodwill will be amortized, see note 2 to the
unaudited pro forma consolidated financial statements included in the section of
this proxy statement/ prospectus entitled "VODAFONE AIRTOUCH UNAUDITED PRO FORMA
CONSOLIDATED FINANCIAL INFORMATION."
 
SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION
 
    Vodafone expects to pay approximately $5.5 billion in cash to holders of
shares of AirTouch common stock in the merger. This amount may vary slightly
depending upon the number of shares of AirTouch common stock outstanding at the
time of the merger, which depends upon the number of AirTouch stock options
exercised prior to the merger, the number of shares of AirTouch Class C
preferred stock converted prior to the merger, the number of shares, if any,
repurchased by AirTouch, and the extent of any exercise of appraisal rights. In
addition, Vodafone and AirTouch currently expect to pay approximately $270
million to cover expenses incurred in connection with the merger. These amounts
will be financed by the new $10.5 billion credit facility entered into by
Vodafone and AirTouch on April 16, 1999 as well as from generally available
funds of Vodafone and AirTouch.
 
    The new credit facility is split into three tranches. Tranche A is a
$4,000,000,000 revolving loan facility and Tranche B a $3,000,000,000 term loan
facility, each of which is available in the first year of the facility. Vodafone
has the option of extending the repayment of advances under those tranches up to
the second anniversary of the date of the facility. Tranche C is a
$3,500,000,000 revolving loan facility, available for five years. Advances may
be drawn in U.S. dollars, sterling and euros.
 
    Facility advances will bear interest at a rate per annum equal to the sum of
(i) the applicable margin, (ii) LIBOR and (iii) the cost to the lenders of
complying with capital adequacy and other regulatory requirements. The
applicable margin varies for each of the tranches according to tranche
utilization and the credit rating assigned to Vodafone AirTouch at the relevant
time, and ranges from 0.45% per annum to 0.80% per annum. Commitment fees of
0.125% per annum for Tranches A and B and 40% of the margin for Tranche C are
also payable on undrawn amounts of the facility.
 
    If there is a change in control of Vodafone, individual lenders may require
that their participation in the facility be cancelled and prepaid if they are
not able to agree to terms on which they are willing to continue to participate
in the facility.
 
    Certain other terms and conditions usual for facilities of this type apply
to the facility, including conditions precedent, prepayment provisions,
representations and warranties, covenants such as compliance with financial
ratios, events of default, indemnities and provisions to protect the margin
receivable by the lenders. Vodafone has the option, at its election, to suspend
the operation of certain specified conditions to the availability of the
facility for up to two months before completion of the merger to provide
certainty of funding.

OTHER EFFECTS OF THE MERGER
 
    The content and timing of reports and notices that Vodafone files and that
Vodafone AirTouch will
file with the SEC differ in several respects from the reports and notices that
AirTouch currently files. Vodafone is, and Vodafone AirTouch will be, a foreign
private issuer for the purposes of the reporting rules under the Exchange Act.
 
    As a U.S. reporting company, AirTouch must file with the SEC, among other
reports and notices,
 
    (1) an annual report on Form 10-K within 90 days after the end of each
fiscal year,
 
    (2) quarterly reports on Form 10-Q within 45 days after the end of each
fiscal quarter, and
 
    (3) reports on Form 8-K upon the occurrence of certain corporate events.
 
    As a foreign private issuer, pursuant to the requirements of the Securities
Exchange Act, Vodafone is, and Vodafone AirTouch will be, required to
 
    (1) file with the SEC an annual report on Form 20-F within six months after
       the end of each fiscal year and
 
    (2) furnish reports on Form 6-K upon the occurrence of significant corporate
       events.
 
Vodafone AirTouch will not be required under the Exchange Act to file quarterly
reports on Form 10-Q after the end of each financial quarter.
 
    In addition, the content and timing of reports and notices that holders of
Vodafone AirTouch ordinary shares and Vodafone AirTouch ADSs will receive will
differ from the reports and notices that are currently received by AirTouch
stockholders. As a U.S. reporting company, AirTouch must mail to its
stockholders in advance of each annual meeting of stockholders
 
    (1) an annual report containing audited financial statements and
 
    (2) a proxy statement that complies with the requirements of the Exchange
       Act.
 
    As a foreign private issuer, Vodafone AirTouch will be exempt from the rules
under the Exchange Act prescribing the furnishing and content of annual reports
and proxy statements to its shareholders. However, Vodafone AirTouch will cause
holders of Vodafone AirTouch ADSs to be furnished with an annual report which
contains audited financial statements prepared in conformity with U.K. GAAP,
including U.S. GAAP reconciliations and a discussion of Vodafone AirTouch's
financial results that is comparable to the management's discussion and analysis
that is contained in AirTouch's annual reports on Form 10-K. Vodafone AirTouch
will also furnish ADS holders with semi-annual interim reports which include
unaudited interim financial information prepared in conformity with U.K. GAAP
and notices of meetings of shareholders and related documents in accordance with
the rules of the London Stock Exchange. As promptly as practicable after each of
those reports is ready for distribution to shareholders, Vodafone AirTouch will
furnish the depositary, The Bank of New York, with sufficient copies of these
reports as well as other communications and notices that Vodafone AirTouch
generally makes available to its shareholders. Then, at the request of Vodafone
AirTouch, the depositary will arrange for the mailing of the documents to
holders of Vodafone AirTouch ADSs as promptly as possible thereafter. Holders of
Vodafone AirTouch ADSs will also be able to obtain from the depositary a copy of
the company's most recent annual report on Form 20-F. The depositary has also
agreed to make these documents available for inspection at the depositary's
office. See "DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY SHARES."
 
    Pursuant to the merger agreement, Vodafone has agreed that, beginning as
soon as practicable after the merger, and in any event within two years thereof,
it will
 
    (1) make filings with the SEC on Form 6-K within 45 days after the end of
       its first three fiscal quarters in each of its fiscal years containing
       the principal financial information required by Form 10-Q, and
 
                                       56
<PAGE>
    (2) make any requisite filings on Form 20-F with the SEC within 90 days
       after the end of each fiscal year.
 
Vodafone currently intends to post Vodafone AirTouch's company annual reports
and other information on its internet web site at www.vodafone.co.uk.
 
    If the merger is completed, the AirTouch common stock and the AirTouch Class
B preferred stock will be delisted from the NYSE and will be deregistered under
the Exchange Act. The AirTouch common stock will also be delisted from the
Pacific Exchange. Shares of AirTouch Class C preferred stock outstanding after
the merger will continue to be listed on the NYSE and, as a result, AirTouch
will continue to be a reporting company under the Exchange Act. When all shares
of AirTouch Class C preferred stock have been redeemed or converted under their
terms, AirTouch will no longer be required by the Exchange Act to be a reporting
company.
 
    AirTouch common stock is presently included in the S&P 500 index. Mutual
funds and other investment vehicles whose investment objective is to track the
performance of the S&P 500 index currently hold a substantial amount of AirTouch
common stock. These funds will be required to sell their AirTouch shares (or the
Vodafone AirTouch ADSs they receive in the merger) if, as is likely after the
merger, AirTouch is removed from the S&P 500. These sales could adversely affect
the market price for the Vodafone AirTouch ADSs.
 
    In addition, after the merger the relative weight of Vodafone AirTouch in
the U.K. series of the Financial Times Stock Exchange Actuaries Indices is
expected to increase. As a result, pension funds, unit trusts and other
investment vehicles whose investment objective is to track the performance of
these indices are likely to increase their holdings of Vodafone AirTouch
ordinary shares.
 
    Due to the additional indebtedness that Vodafone will incur in connection
with the merger as well as the rating differential of the existing indebtedness
of the two companies, Standard & Poor's and Moody's Investor Services may
downgrade Vodafone's corporate credit ratings. Vodafone and AirTouch believe,
however, that any resulting increase in the net borrowing costs of the combined
company arising from a downgrade after the merger would not be material.
 
    AirTouch's U.S. personal communications services operations are carried out
jointly within its PrimeCo partnership with Bell Atlantic Mobile. AirTouch and
Bell Atlantic Mobile are equal partners in PrimeCo, whose markets complement the
existing U.S. cellular franchises of the partners. PrimeCo began providing
service in November 1996 and at December 31, 1998 had over 902,000 customers.
Bell Atlantic stated in a proxy statement dated April 13, 1999 that upon
completion of the Vodafone/ AirTouch merger, Bell Atlantic intends to exercise
its option to dissolve PrimeCo and divide PrimeCo's personal communications
services properties with AirTouch in accordance with procedures contained in the
PrimeCo partnership agreement. Neither Vodafone nor AirTouch believes that such
a dissolution would have a material adverse effect on the combined company.
 
CERTAIN LITIGATION
 
    AirTouch has recently been served with complaints in the following two
matters:
 
    In March 1999, customers of AirTouch filed a class action complaint in Los
Angeles County Superior Court against AirTouch challenging the legality of the
assessment of an early disconnection charge when a customer terminates service
under a contract whose duration has been extended upon the acceptance of a new
promotional offer. The plaintiffs are seeking injunctive relief and unspecified
monetary damages, including disgorgement of monies obtained as a result of the
alleged unlawful business practices.
 
    In April 1999, a complaint was filed against AirTouch in the State of
Michigan on behalf of all individuals subscribing to service in that state. The
plaintiffs are challenging the legality of AirTouch's assessment of certain
charges for local calls and charges for calls that pass through wireline
networks. The plaintiffs are seeking injunctive relief and unspecified monetary
damages.
 
                                       57
<PAGE>
    In addition, on January 6, 1999, a lawsuit against AirTouch was filed in
U.S. District Court for the Central District of California alleging that a
January 3, 1999 AirTouch press release was false and misleading under Rule 10b-5
promulgated under the Exchange Act because it failed to disclose material
information about AirTouch's merger discussions. The complaint, filed as a
purported class action on behalf of all sellers of AirTouch common stock and
options on January 3, 1999, seeks an unspecified amount of damages.
 
    Also, shortly after execution of the merger agreement was announced, Bell
Atlantic, AirTouch's 50/50 partner in the PrimeCo and TOMCOM joint ventures,
filed a lawsuit seeking to void provisions in the joint venture agreements
limiting the partners' competitive activities outside of the joint ventures.
Bell Atlantic is seeking preliminary and permanent injunctive relief to void
these provisions. The court has set the matter for hearing on May 24, 1999.
 
    Each of the aforementioned cases is in the preliminary phase and AirTouch is
not currently able to assess the impact, if any, of the cases on its financial
position or results of operations. AirTouch intends to vigorously oppose each of
these actions.

<PAGE>
                          THE INTERNAL REORGANIZATION
 
    The purpose of the internal reorganization is to amend AirTouch's
certificate of incorporation to satisfy requirements to permit the
Vodafone/AirTouch merger to be tax-free to U.S. holders of AirTouch common
stock, except with respect to cash received in the merger. If AirTouch
stockholders approve and adopt the agreement providing for the AirTouch internal
reorganization and the agreement is not otherwise terminated, AirTouch will
cause AirTouch Merger Sub, a newly-formed wholly owned subsidiary of AirTouch,
to merge with and into AirTouch, with AirTouch being the surviving corporation.
AirTouch Merger Sub will not have conducted any material business prior to the
time of the internal reorganization. In connection with the internal
reorganization, appraisal rights will be available to the holders of AirTouch
Class D preferred stock and AirTouch Class E preferred stock who comply with the
applicable provisions of Delaware law. The following is only a description of
the internal reorganization to be effected. You are encouraged to read the
complete text of the merger agreement between AirTouch and AirTouch Merger Sub
which is attached hereto as Appendix D. The terms of this agreement supersede
the description of the internal reorganization contained in the merger agreement
between Vodafone and AirTouch.
 
    After completion of the internal reorganization,
 
    (1) each share of AirTouch common stock outstanding immediately prior to the
       internal reorganization will remain outstanding as a share of AirTouch
       common stock;
 
    (2) each share of AirTouch Class B preferred stock outstanding immediately
       prior to the internal reorganization will remain outstanding as a share
       of AirTouch Class B preferred stock;
 
    (3) each share of AirTouch Class C preferred stock outstanding immediately
       prior to the internal reorganization will remain outstanding as a share
       of AirTouch Class C preferred stock;
 
    (4) each share of AirTouch Class D preferred stock outstanding immediately
       prior to the internal reorganization, except for shares with respect to
       which holders have asserted appraisal rights, will remain outstanding as
       a share of AirTouch Class D preferred stock; and
 
    (5) each share of AirTouch Class E preferred stock outstanding immediately
       prior to the internal reorganization, except for shares with respect to
       which holders have asserted appraisal rights, will remain outstanding as
       a share of AirTouch Class E preferred stock.
 
    Subject to approval and adoption of the agreement providing for the internal
reorganization by the holders of AirTouch common stock and AirTouch Class B
preferred stock representing not less than a majority of the voting power of the
AirTouch common stock and the AirTouch Class B preferred stock entitled to vote
thereon, voting as a single class, the closing of the internal reorganization
will occur as soon as practicable after the special meeting of AirTouch
stockholders but in no event later than the day prior to the date of the
Vodafone/AirTouch merger. See "THE SPECIAL MEETING."
 
    Under the internal reorganization, the AirTouch certificate of incorporation
will be amended to provide that, after the reorganization:
 
    (1) the holders of AirTouch Class C preferred stock will be entitled to vote
       together with the holders of AirTouch common stock on all matters to be
       voted upon by holders of AirTouch common stock, and each share of
       AirTouch Class C preferred stock will be entitled to 1.379 votes per
       share of AirTouch Class C preferred stock. Upon redemption of AirTouch
       Class C preferred stock after the merger, a holder of any redeemed Class
       C preferred share will be entitled to receive that number of Vodafone
       AirTouch ADSs and that amount of cash as that holder would have been
       entitled to receive in the merger had the holder held that number of
       shares of AirTouch common stock that the holder would have received had
       AirTouch redeemed such holder's AirTouch Class C preferred stock
       immediately prior to the merger;
 
                                       59
<PAGE>
    (2) the holders of AirTouch Class D preferred stock will be entitled to vote
       together with the holders of AirTouch common stock on all matters to be
       voted upon by the holders of AirTouch common stock on the basis of 12
       votes for each share of AirTouch Class D preferred stock held, AirTouch
       will no longer be able to redeem the AirTouch Class D preferred stock
       prior to its maturity date of April 6, 2020, and AirTouch will not be
       able to change the maturity date or any dividend payment date for these
       shares, decrease the amount of any dividend, redemption or liquidation
       payment to holders of the AirTouch Class D preferred stock or enter into
       a merger that would result in the AirTouch Class D preferred stock being
       converted into cash, in each case without the consent of the holders of a
       majority of these shares, and
 
    (3) the holders of AirTouch Class E preferred stock will be entitled to vote
       together with the holders of AirTouch common stock on all matters to be
       voted upon by holders of AirTouch common stock on the basis of 12 votes
       for each share of AirTouch Class E preferred stock, the maturity date of
       the AirTouch Class E preferred stock will be extended from April 7, 2018
       to April 1, 2020, the dividend payable to the holders of the AirTouch
       Class E preferred stock on the first dividend payment date after the
       effective time of the internal reorganization will be increased by $25.00
       to $37.8575, and AirTouch will not be able to change the maturity date or
       any dividend payment date for these shares, decrease the amount of any
       dividend, redemption or liquidation payment to holders of the AirTouch
       Class E preferred stock or enter into a merger agreement that would
       result in the AirTouch Class E preferred stock being converted into cash,
       in each case without the consent of the holders of a majority of these
       shares.
 
    The changes to the AirTouch certificate of incorporation to be effected
pursuant to the internal reorganization will not affect any of the powers,
preferences or rights of the AirTouch common stock or AirTouch Class B preferred
stock.

                               REGULATORY MATTERS
 
    Under the merger agreement, neither party is required to complete the merger
unless all required regulatory consents and approvals that would be material to
Vodafone and AirTouch on a combined basis are obtained without any restrictions
or conditions that would have a material adverse effect on Vodafone and AirTouch
on a combined basis. It is possible that these regulatory consents and approvals
will not be obtained at all or on a timely basis or that material conditions
will be imposed on these consents and approvals. See "THE MERGER
AGREEMENT--Conditions."
 
FEDERAL COMMUNICATIONS COMMISSION
 
    The merger is subject to the requirements of the Communications Act of 1934
and the rules, regulations and policies of the Federal Communications
Commission. Under FCC rules, the acquisition by Vodafone of all outstanding
AirTouch common stock is deemed to result in a change in control of AirTouch and
its subsidiaries holding FCC authorizations and licenses and, as a result, prior
FCC approval must be obtained. Under the Communications Act, the FCC must
determine that the proposed change in control serves the public interest,
convenience and necessity before it can approve the transaction. In making this
determination, the FCC examines whether a proposed transfer is consistent with
the policies of the Communications Act, including, among other things, the
effect of the proposed transfer on FCC policies encouraging competition.
 
    The FCC will also consider whether the application satisfies the framework
for a non-U.S. carrier to enter into the U.S. telecommunications market. The
Communications Act allows a non-U.S. investor to acquire up to a 25% ownership
interest in the parent company of a U.S. common carrier radio licensee without
FCC approval, and the FCC has discretion to authorize indirect non-U.S.
ownership exceeding 25% if it finds that this ownership would not be
inconsistent with the public interest. The FCC has adopted a presumption in
favor of permitting non-U.S. entities from World Trade Organization member
states, including the United Kingdom, to acquire up to a 100% indirect interest
in a U.S. common carrier radio licensee. The FCC reserves the right to deny an
application in the exceptional case where entry into the U.S. market by a
non-U.S. telecommunications carrier from a WTO member state poses a very high
risk to competition in the U.S. market.
 
    Vodafone and AirTouch filed with the FCC applications requesting the FCC's
consent to the change in control of AirTouch's radio licenses on February 3,
1999. These FCC applications were placed on public record on February 8, 1999.
Vodafone and AirTouch believe it is likely that the FCC will grant these
applications. However, the FCC applications are subject to public comment,
petitions to deny, and informal objections by third parties who may object in an
attempt to delay or impede approval by the FCC. The period for filing and
responding to public comments on the FCC applications expired on March 29, 1999,
but several comments and objections were filed prior to the March 29 deadline.
Vodafone and AirTouch have responded to those comments and objections.
Accordingly, it is possible that the FCC will not grant the FCC applications in
a timely fashion, will subject their approval to conditions or restrictions or
will not grant the FCC applications at all.

    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
and the rules promulgated thereunder, the merger may not be completed unless
specific waiting period requirements have been satisfied. On February 4, 1999,
Vodafone and AirTouch each filed a premerger notification and report form under
the HSR Act with the Antitrust Division of the Department of Justice and the
Federal Trade Commission. Early termination of the applicable waiting period
under the HSR Act was granted on March 2, 1999.

EXON-FLORIO
 
    The provisions of Exon-Florio under the Omnibus Trade and Competitiveness
Act of 1988 empower the President of the United States to prohibit or suspend an
acquisition of, or investment in, a U.S. company by a non-U.S. company if the
President finds, after investigation, credible evidence that the non-U.S. person
might take action that threatens to impair the national security of the U.S. and
that provisions of existing law do not provide adequate and appropriate
authority to protect the national security. Any determination that an
investigation is called for must be made within 30 days of notice of the
proposed transaction. If a determination is made, any investigation must be
completed within 45 days of the determination and any decision to take action
must be announced within 15 days of completion of the investigation.
 
    On March 4, 1999, Vodafone and AirTouch filed a voluntary notice under
Exon-Florio requesting confirmation that the merger does not threaten to impair
the national security of the United States. On April 5, 1999 the Department of
the Treasury granted the request of Vodafone and AirTouch to withdraw the March
4 voluntary notice on the ground that the only issues raised in the review of
that notice were identical to those raised in the FCC proceedings. Vodafone and
AirTouch believe that they will be able to reach agreement on these issues in
the context of the FCC review process. If and when the FCC order is issued,
Vodafone and AirTouch may file a new voluntary notice under Exon-Florio.
 
STATE REGULATORY APPROVALS
 
    Vodafone and AirTouch have filed applications to seek prior approval of the
merger from the Georgia Public Service Commission, the Louisiana Public Service
Commission and the Nevada Public Utilities Commission and all three commissions
have granted approval of the merger. In addition to the aforementioned state
applications, Vodafone and AirTouch have filed mandatory notices of the merger
with the California Public Utilities Commission, the Kentucky Public Service
Commission, the New Mexico Public Regulation Commission, the Ohio Public
Utilities Commission and the Wisconsin Public Service Commission. A request has
been filed with the Ohio Public Utilities Commission to suspend the
effectiveness of the notice filed by Vodafone and AirTouch, and Vodafone and
AirTouch have opposed that request. Notwithstanding the Ohio proceeding,
Vodafone and AirTouch believe that it is likely that all of the notices filed at
the state public service commissions will become effective other than those the
failure of which to be obtained would not have a material adverse effect on
Vodafone and AirTouch on a combined basis. It is possible, however, that the
Ohio Public Utilities Commission will suspend the effectiveness of the Vodafone
and AirTouch notice pending further proceedings or will subject such notice to
conditions or restrictions. No further state filings or approvals are required.
 
EUROPEAN UNION
 
    Vodafone and AirTouch each conducts business in member states of the
European Union. Council Regulation (EEC) 4064/89, as amended, requires
notification to and approval by the European Commission of mergers or
acquisitions involving parties with aggregate worldwide sales and individual
European Union sales exceeding specified thresholds before these mergers or
acquisitions are implemented. Vodafone and AirTouch filed a merger notification
with the European Union antitrust authorities on April 6, 1999.
 
    The European Commission must review the merger to determine whether or not
it is compatible with the common market and, accordingly, whether or not to
permit it to proceed. A merger or acquisition which does not create or
strengthen a dominant position that would significantly impede effective
competition in the common market or in a substantial part of it shall be
declared compatible with the common market, and must be allowed to proceed. If,
following a preliminary one month Phase I investigation, the European Commission
considers that it needs to examine the merger more closely because it raises
serious doubts as to its compatibility with the common market, it must initiate
 
                                       62
<PAGE>
further Phase II investigation procedures. If it initiates a Phase II
investigation, the European Commission must issue a final decision as to whether
or not the merger is compatible with the common market no later than four months
after the initiation of the Phase II investigation. If no Phase II investigation
is initiated, then at the end of the Phase I investigation, the European
Commission will issue a decision declaring the merger to be compatible with the
common market, thereby allowing the merger to proceed. If the European
Commission has not issued a final decision by the end of the Phase I
investigation or, if Phase II proceedings have been initiated, the Phase II
investigation, the merger is deemed cleared. The Phase I investigation period
may be extended to six weeks if, within three weeks of receipt of the
notification, a member state requests the European Commission to refer all or
part of the merger back to the competent authority of the member state
concerned, or, if after the notification, the notifying parties offer
commitments to the European Commission during the Phase I investigation to
remedy any antitrust concerns.
 
    Vodafone and AirTouch believe that the European Commission should declare
the proposed merger compatible with the common market under Council Regulation
(EEC) 4064/89, as amended, although in order to obtain clearance of the merger,
Vodafone expects to enter into an undertaking with the European Commission to
sell its participation in its German affiliate, E-Plus Mobilfunk GmbH. It is
also possible that the European Commission will initiate a Phase II
investigation or that the European Commission may declare the merger
incompatible with the common market.
 
UNITED KINGDOM
 
    Vodafone conducts business and holds a number of telecommunications and
wireless telegraphy licenses in the United Kingdom. No approvals or
notifications under its licenses are required in the United Kingdom to complete
the merger because there will be no change in control of any of the Vodafone
licensed companies.
 
OTHER LAWS
 
    Under Polish communications regulations, Vodafone must obtain approval from
the Minister of Telecommunications prior to completion of the merger. On April
21, 1999, Polkomtel, S.A., AirTouch's Polish affiliate, filed an application to
seek prior approval of the merger from the Minister of Telecommunications.
Vodafone and AirTouch believe that it is likely that the Minister of
Telecommunications will grant the necessary approval. It is possible, however,
that the Minister of Telecommunications will not grant the approval in a timely
fashion or will subject its approval to conditions or restrictions.
 
    In addition, under Polish law, the merger may not be completed unless the
Polish Office of Competition and Consumer Protection issues its approval of the
transaction or specified waiting period requirements have been satisfied. On
February 15, 1999 AirTouch filed and on March 2, 1999 Vodafone filed a
Notification of Intended Merger of Entities with the Polish Office of
Competition and Consumer Protection pursuant to this antitrust law. The Polish
Competition Office granted approval of the merger on April 13, 1999.
 
    The German national regulatory authority, REGULIERUNGSBEHORDE FUR
TELEKOMMUNIKATION UND POST, has advised AirTouch's German affiliate, Mannesmann
Mobilfunk, that it must obtain approval from such authority for the change in
ownership of Mannesmann Mobilfunk prior to completion of the merger. Mannesmann
Mobilfunk will shortly file an application to seek prior approval for this
change. Vodafone and AirTouch believe that it is likely that this approval will
be granted. It is possible, however, that approval will not be granted in a
timely manner or will be subject to conditions or restrictions.
 
    Notifications of the merger will be required under the relevant
telecommunications licenses in France. The French mobile operator in which
Vodafone is a shareholder, SFR, will have to notify the
 
                                       63
<PAGE>
French telecommunications regulator, ART, of the new capital structure of
Vodafone following the merger. The notification must include a description of
the new capital structure of Vodafone following the merger, details of the
anticipated changes in the composition of Vodafone's shareholdings and the
timetable for the merger. Provided that this notification is made, the ART will
not have any grounds upon which to object to the merger.
 
    Vodafone and AirTouch conduct operations in a number of jurisdictions where
other regulatory filings or approvals may be required or advisable in connection
with the completion of the merger. Vodafone and AirTouch are currently in the
process of reviewing whether filings or approvals may be required or desirable
in these jurisdictions which may be material to Vodafone and AirTouch and its
subsidiaries. It is possible that one or more of these filings may not be made,
or one or more of these approvals, which are not as a matter of practice
required to be obtained prior to effectiveness of a merger transaction, may not
be obtained, prior to the merger.
 
GENERAL
 
    It is possible that one or more of the regulatory approvals required to
complete the merger will not be obtained on a timely basis or at all. In
addition, it is possible that any of the governmental entities with which
filings are made may seek, as conditions for granting approval of the merger,
regulatory concessions. Under the merger agreement, if any regulatory body's
approval is subject to conditions or restrictions that would have a material
adverse effect on Vodafone or AirTouch on a combined basis, either Vodafone or
AirTouch can elect not to complete the merger. It is possible that Vodafone or
AirTouch will not be able to comply with conditions imposed or that compliance
or non-compliance will have adverse consequences for Vodafone AirTouch after
completion of the merger. See "THE MERGER AGREEMENT--Conditions."

                           MATERIAL TAX CONSEQUENCES
 
GENERAL
 
    The following is a discussion of the material U.S. federal income tax
consequences of the internal reorganization and the merger to U.S. holders of
AirTouch common stock, AirTouch Class B preferred stock and AirTouch Class C
preferred stock and the material U.S. federal income tax considerations and
United Kingdom tax considerations applicable to the ownership of Vodafone
AirTouch shares by U.S. holders. Subject to the limitations and qualifications
set forth herein, the following description of the U.S. federal income tax
consequences relating to the internal reorganization and the merger represents
the opinion of Sullivan & Cromwell, U.S. tax counsel to Vodafone, and Fried,
Frank, Harris, Shriver & Jacobson, U.S. tax counsel to AirTouch, respectively,
as to all of the material U.S. Federal income tax consequences of the internal
reorganization and the merger. As used herein, a "U.S. holder" means a
beneficial owner of an AirTouch share or option to acquire an AirTouch share who
is treated as a United States person for U.S. federal income tax purposes. This
discussion does not address all aspects of U.S. federal income taxation or
United Kingdom taxation that may be relevant to AirTouch stockholders in light
of their particular circumstances, or to stockholders who are subject to special
provisions of U.S. federal income tax law. In addition, this discussion is
limited to stockholders who hold AirTouch shares as capital assets and who will
hold Vodafone AirTouch shares as capital assets. See "--Qualifications," below.
The opinions of counsel are based upon
 
    - a private letter ruling, dated April 12, 1999, that Vodafone and AirTouch
      received from the U.S. Internal Revenue Service addressing certain issues
      under Section 367(a)(1) of the U.S. tax code, a copy of which is attached
      as Exhibit 99(d) to the registration statement of which this document
      forms a part,
 
    - factual representations of Vodafone and AirTouch contained in certificates
      signed by officers of Vodafone and AirTouch, copies of which are attached
      to the tax opinions included as Exhibits 8(a) and 8(b) to the registration
      statement, and
 
    - the assumption that the merger and internal reorganization will be
      completed according to the terms of the merger agreements.
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS OF AIRTOUCH COMMON
STOCK AND AIRTOUCH CLASS B PREFERRED STOCK
 
    The internal reorganization will not be a taxable event to U.S. holders of
AirTouch common stock or AirTouch Class B preferred stock. U.S. holders of
AirTouch common stock or AirTouch Class B preferred stock will therefore not
recognize any gain or loss in connection with the internal reorganization.
 
    The merger will be a tax-free reorganization for U.S. federal income tax
purposes. Accordingly, U.S. holders of AirTouch common stock, including U.S.
holders of AirTouch Class B preferred stock whose shares are automatically
converted into AirTouch common stock immediately prior to the effective time of
the merger, will not recognize loss, but will recognize gain in an amount equal
to the lesser of the gain realized, if any, with respect to each share of
AirTouch common stock exchanged and any cash received in exchange for the share
of AirTouch common stock. The amount of gain realized with respect to each share
of AirTouch common stock exchanged will equal the excess of the sum of the fair
market value of the portion of a Vodafone AirTouch ADS and the amount of any
cash received for the AirTouch share over the U.S. holder's tax basis in such
share. As further discussed below, different rules apply to cash received in
lieu of fractional shares and to any stockholder of AirTouch who will own,
actually or constructively, at least five percent of Vodafone AirTouch by vote
or value immediately after the merger.
 
    Subject to the following sentence, any recognized gain will be capital gain,
and will be long-term capital gain with respect to AirTouch common stock held
for more than 12 months at the effective time
 
                                       65
<PAGE>
of the merger. However, the gain could be treated as dividend income to an
AirTouch shareholder who either will exercise some control with respect to
corporate affairs or will own, actually or constructively, more than a very
small percentage interest in Vodafone AirTouch.
 
    The tax basis of each Vodafone AirTouch ADS received in the merger will
equal the tax basis of the AirTouch common stock exchanged therefor, increased
by the amount of gain (including any gain that is treated like a dividend)
recognized with respect to the exchange of those shares, decreased by the basis
of any portion of those exchanged shares converted into cash in lieu of a
fractional Vodafone AirTouch ADS, and further decreased by the amount of cash
received with respect to those exchanged shares (other than cash received in
lieu of a fractional Vodafone AirTouch ADS). The holding period of the Vodafone
AirTouch ADSs will include the holding period of the AirTouch common stock
exchanged therefor.
 
    If a U.S. holder of AirTouch common stock receives cash in lieu of a
fractional Vodafone AirTouch ADS, the cash amount will be treated as received in
exchange for the fractional Vodafone AirTouch ADS. Subject to the rule discussed
above with respect to gain recognized in the merger, the difference between the
cash amount received for the fractional Vodafone AirTouch ADS and the proportion
of the U.S. holder's tax basis in AirTouch common stock exchanged and allocable
to the fractional Vodafone AirTouch ADS will be capital gain or loss. The
capital gain or loss will be long-term capital gain or loss with respect to
shares of AirTouch common stock held for more than 12 months at the effective
time of the merger.
 
    AN AIRTOUCH SHAREHOLDER WHO WILL OWN, ACTUALLY OR CONSTRUCTIVELY, AT LEAST
FIVE PERCENT OF VODAFONE AIRTOUCH BY VOTE OR VALUE IMMEDIATELY AFTER THE MERGER
WILL QUALIFY FOR NON-RECOGNITION TREATMENT AS DESCRIBED HEREIN ONLY IF THE
SHAREHOLDER FILES A "GAIN RECOGNITION AGREEMENT" WITH THE IRS. ANY SUCH
SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER TAX ADVISOR CONCERNING THE
DECISION TO FILE A "GAIN RECOGNITION AGREEMENT" AND THE PROCEDURES TO BE
FOLLOWED IN CONNECTION WITH THAT FILING.
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS OF AIRTOUCH CLASS
C PREFERRED STOCK
 
    UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE INTERNAL REORGANIZATION
    TO U.S. HOLDERS OF AIRTOUCH CLASS C PREFERRED STOCK
 
    The internal reorganization will be a recapitalization to holders of
AirTouch Class C preferred stock unless the AirTouch Class C preferred stock is
not considered "nonqualified preferred stock" within the meaning of Section
351(g) of the U.S. tax code prior to the internal reorganization and is
considered nonqualified preferred stock after the internal reorganization.
Nonqualified preferred stock is stock which, among other things, does not
participate in corporate growth to any significant extent. Although the matter
is not free from doubt, it is the opinion of tax counsel to AirTouch and
Vodafone that it is reasonable for a holder of AirTouch Class C preferred stock
to take the position that the AirTouch Class C preferred stock does participate
in corporate growth to some significant extent both prior to, and subsequent to,
the internal reorganization because:
 
    - the AirTouch Class C preferred stock participates on an as-converted basis
      with the AirTouch common stock on a liquidation of AirTouch after certain
      preferences have been satisfied, and
 
    - the AirTouch Class C preferred stock is convertible into AirTouch common
      stock both presently and immediately after the internal reorganization.
 
    Therefore, although the matter is not free from doubt, it is the opinion of
tax counsel to AirTouch and Vodafone that it is reasonable for a holder of
AirTouch Class C preferred stock to take the position that the internal
reorganization is tax-free to the holder.
 
    However, subsequent to the merger, and shortly after the internal
reorganization, the AirTouch Class C preferred stock will not be convertible
into AirTouch common stock but instead will be convertible into Vodafone
AirTouch ADSs. A right to convert stock into stock of a corporation other
 
                                       66
<PAGE>
than the issuer thereof (for example, stock of a parent corporation) is not
considered to constitute participation in corporate growth to any significant
extent. Accordingly, by reason of the short period of time between the internal
reorganization and the merger, it is possible that the IRS will successfully
assert that the conversion rights should not be considered to provide holders of
AirTouch Class C preferred stock participation in corporate growth. Further,
there is no authority directly addressing whether liquidation rights like the
liquidation rights attaching to the AirTouch Class C preferred stock would be
considered to constitute participation in corporate growth to any significant
extent for this purpose or otherwise addressing the treatment of shares such as
the AirTouch Class C preferred stock for this purpose. Accordingly, there can be
no assurance that the IRS will not successfully assert that the internal
reorganization is taxable, in whole or in part, to U.S. holders of AirTouch
Class C preferred stock.
 
    UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO U.S. HOLDERS
    OF AIRTOUCH CLASS C PREFERRED STOCK
 
    The merger will not be a taxable event to U.S. holders of AirTouch Class C
preferred stock. U.S. holders of AirTouch Class C preferred stock will therefore
not recognize any gain or loss in connection with the merger.
 
    CONVERSION OR REDEMPTION OF AIRTOUCH CLASS C PREFERRED STOCK SUBSEQUENT TO
    THE MERGER
 
    The conversion or redemption of AirTouch Class C preferred stock into, or
for, Vodafone AirTouch ADSs following completion of the merger will be taxable
to U.S. holders of AirTouch Class C preferred stock, except if the AirTouch
Class C preferred stock so converted is considered exchanged in the merger
transaction within the meaning of the reorganization provisions of the U.S. tax
code. Accordingly, unless the foregoing exemption applies, a U.S. holder will
recognize capital gain or loss equal to the excess, if any, of the aggregate
fair market value of the Vodafone AirTouch ADSs and any cash received in the
conversion or redemption over the aggregate tax basis of the AirTouch Class C
preferred stock converted or redeemed. AirTouch is expected to have the right to
redeem AirTouch Class C preferred stock not previously converted into AirTouch
common stock or exchanged for Vodafone AirTouch ADSs beginning September 20,
1999 for the consideration receivable in the merger by a holder of AirTouch
common stock having a value of fifty dollars.
 
    A U.S. HOLDER OF AIRTOUCH CLASS C PREFERRED STOCK THAT PRIOR TO COMPLETION
OF THE INTERNAL REORGANIZATION EXERCISES ITS RIGHT TO CONVERT ITS AIRTOUCH CLASS
C PREFERRED STOCK INTO AIRTOUCH COMMON STOCK WILL NOT RECOGNIZE GAIN OR LOSS AS
A RESULT OF THE CONVERSION OR THE INTERNAL REORGANIZATION. FOLLOWING CONVERSION,
A U.S. HOLDER WILL BE SUBJECT TO THE TREATMENT DESCRIBED HEREIN WITH RESPECT TO
U.S. HOLDERS OF AIRTOUCH COMMON STOCK. EACH U.S. HOLDER OF AIRTOUCH CLASS C
PREFERRED STOCK IS THEREFORE STRONGLY URGED TO CONSIDER WHETHER, PRIOR TO THE
INTERNAL REORGANIZATION, THE U.S. HOLDER SHOULD CONVERT ITS SHARES OF AIRTOUCH
CLASS C PREFERRED STOCK INTO AIRTOUCH COMMON STOCK.
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS OF EMPLOYEE STOCK
OPTIONS
 
    The exchange pursuant to the merger by a U.S. holder of an option to acquire
a share of AirTouch common stock received as compensation for services for an
option to acquire Vodafone AirTouch shares will not be taxable for U.S. federal
income tax purposes. A U.S. holder of an option to acquire a share of AirTouch
common stock or, after the merger, of an option to acquire a Vodafone AirTouch
share, who received the option as compensation for services and who exercises
the option will, subject to the discussion below, recognize ordinary income for
U.S. federal income tax purposes in an amount equal to the excess of the fair
market value on the exercise date of the stock received pursuant to such
exercise over the price paid for that stock pursuant to the option. A U.S.
holder's basis in stock received pursuant to the exercise of such an option will
equal the fair market value of the stock on the exercise date. Thereafter, the
U.S. holder will be subject to the rules discussed above with respect to
 
                                       67
<PAGE>
U.S. holders of AirTouch common stock or discussed below with respect to U.S.
holders of Vodafone AirTouch shares. The foregoing discussion does not address
the U.S. federal income tax consequences of the exercise of any option that is
treated as an incentive stock option within the meaning of section 422(b) of the
U.S. tax code. Any U.S. holder of an option that is treated as an incentive
stock option is urged to consult his or her own tax advisor concerning the
consequences to him or her of the merger and exercise of the option.
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO DISSENTING STOCKHOLDERS
 
    Subject to the discussion below, a U.S. holder who exercises the holder's
right to dissent from the merger will recognize gain or loss on the exchange of
the holder's AirTouch stock for cash in an amount equal to the difference
between the amount of cash received (other than amounts, if any, which are or
are deemed to be interest for federal income tax purposes, which amounts will be
taxed as ordinary income) and the holder's basis in its AirTouch stock, and the
gain or loss will be capital gain or loss if the AirTouch shares were held as
capital assets at the effective time of the merger. The capital gain or loss
will be long-term capital gain or loss with respect to AirTouch stock held for
more than 12 months at that time. A dissenting stockholder may be required to
recognize any resulting gain or loss in the year the merger closes, irrespective
of whether the dissenting stockholder actually receives payment for his or her
shares in that year. In some instances, cash received by a dissenting AirTouch
stockholder could be taxed as a dividend if the stockholder actually or
constructively owns Vodafone AirTouch ADSs immediately after the merger.
 
TAX OPINIONS AND PRIVATE LETTER RULING
 
    It is a waivable condition to the merger that at the closing Vodafone and
AirTouch each receive a tax opinion from its tax counsel that the merger
qualifies as a reorganization within the meaning of Section 368(a) of the U.S.
tax code and that the merger will be tax-free to the U.S. holders of AirTouch
stock, except with respect to cash received. These opinions will be based upon
updated representations of Vodafone and Airtouch contained in certificates
signed by officers of Vodafone and AirTouch to be delivered at the time of the
merger, the private letter ruling addressing issues under Section 367(a)(1) of
the U.S. tax code and the assumptions noted in the opinions. These opinions are
in addition to the opinions filed with the registration statement of which this
document forms a part. Neither AirTouch nor Vodafone will seek any other ruling
from the IRS as to the U.S. federal income tax treatment of the merger.
 
    The private letter ruling that Vodafone and AirTouch have received from the
IRS is based on the facts and representations contained in the request for the
private letter ruling. While generally binding on the IRS, the private letter
ruling may be retroactively revoked or modified by the IRS if there has been a
misstatement or omission of material facts, the facts at the time of merger are
materially different from the facts upon which the private letter ruling is
based, the representations upon which the private letter ruling is based are
incomplete or untrue in a material respect or there has been a change in
applicable law.
 
    The merger agreement permits each of Vodafone and AirTouch to waive the
receipt of its counsel's opinion as a condition to its obligation to consummate
the merger. AirTouch will not waive this condition without first recirculating
revised proxy materials and resoliciting the vote of the AirTouch stockholders.
The tax opinions will not be binding on the IRS or a court and will not preclude
the IRS or a court from adopting a contrary position.
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE OWNERSHIP OF VODAFONE
AIRTOUCH ORDINARY SHARES AND VODAFONE AIRTOUCH ADSS
 
    For United States federal income tax purposes, U.S. holders of Vodafone
AirTouch ADSs will be treated as the owners of the underlying ordinary shares
that are represented by Vodafone AirTouch
 
                                       68
<PAGE>
ADSs, and deposits and withdrawals of Vodafone AirTouch ordinary shares by U.S.
holders in exchange for Vodafone AirTouch ADSs will not be subject to United
States federal income tax.
 
    TAXATION OF DIVIDENDS
 
    Dividends paid to a U.S. holder by Vodafone AirTouch with respect to the
Vodafone AirTouch shares will be taxable as ordinary income to the U.S. holder
for U.S. federal income tax purposes to the extent paid out of Vodafone
AirTouch's current or accumulated earnings and profits, as determined for United
States federal income tax purposes, based on the U.S. dollar value of the
dividend on the date the dividend is actually or constructively received by the
depositary, in the case of Vodafone AirTouch ADSs, or by the U.S. holder, in the
case of Vodafone AirTouch ordinary shares, calculated by reference to the
exchange rate on the relevant date.
 
    Under the U.K.-U.S. tax treaty a beneficial owner of a Vodafone AirTouch
share and of any cash dividend paid with respect thereto who is a United States
person for U.S. federal income tax purposes and who is eligible for benefits
under the U.K.-U.S. tax treaty with respect to income derived in connection with
such shares (each such holder referred to as an eligible U.S. holder) who
receives a dividend from Vodafone AirTouch may be entitled to a foreign tax
credit for United Kingdom tax withheld. If an eligible U.S. holder is so
entitled, the foreign tax credit would be equal to one-ninth of any dividend
received and would give rise to additional dividend income in the same amount.
Eligible U.S. holders that do not elect, or are not permitted, to claim a
foreign tax credit may be entitled to claim a deduction for foreign tax
withheld. By reason, in part, of recent amendments to the relevant provisions of
United Kingdom tax law, the United States and the United Kingdom have entered
into negotiations of a new income tax treaty. EACH U.S. HOLDER IS URGED TO
CONSULT HIS OR HER TAX ADVISOR CONCERNING WHETHER THE U.S. HOLDER IS ELIGIBLE
FOR BENEFITS UNDER THE U.K.-U.S. TAX TREATY AND WHETHER, AND TO WHAT EXTENT, A
FOREIGN TAX CREDIT OR DEDUCTION WILL BE AVAILABLE WITH RESPECT TO DIVIDENDS
RECEIVED FROM VODAFONE AIRTOUCH.
 
    Each eligible U.S. holder that relies on the U.K.-U.S. tax treaty should
consider disclosing this reliance on the eligible U.S. holder's U.S. federal
income tax return. A U.S. holder that fails to disclose reliance on a treaty
where disclosure is required would be subject to penalties under United States
federal income tax law.
 
    Distributions by Vodafone AirTouch in excess of current and accumulated
earnings and profits, as determined for U.S. federal income tax purposes, will
be treated as a return of capital to the extent of the eligible U.S. holder's
basis in its Vodafone AirTouch shares and thereafter as capital gain. Dividends
paid by Vodafone AirTouch will not be eligible for the dividends-received
deduction allowed to U.S. corporations in respect of dividends received from
other U.S. corporations. U.S. holders should consult their own tax advisors
regarding the treatment of any foreign currency gain or loss on any pounds
sterling received on the Vodafone AirTouch shares which are not converted into
U.S. dollars on the date the pounds sterling are actually or constructively
received by the depositary, in the case of Vodafone AirTouch ADSs, or by the
U.S. holder, in the case of Vodafone AirTouch ordinary shares. For foreign tax
credit limitation purposes, dividends paid by Vodafone AirTouch will be income
from sources outside of the United States.
 
    It is possible that, after the merger, Vodafone AirTouch will be at least
50% owned by persons treated as United States persons under the U.S. tax code.
Under Section 904(g) of the U.S. tax code, dividends paid by a non-U.S.
corporation that is at least 50% owned by U.S. persons may be treated as U.S.
source income rather than non-U.S. source income for foreign tax credit purposes
to the extent the non-U.S. corporation has more than an insignificant amount of
U.S. source income. The effect of this rule may be to treat a portion of the
dividends paid by Vodafone AirTouch as United States source income. Such
treatment may adversely affect an eligible U.S. holder's ability to use foreign
tax credits. Section 904(g)(10) of the U.S. tax code permits an eligible U.S.
holder to elect to treat Vodafone
 
                                       69
<PAGE>
AirTouch dividends as non-U.S. source income for foreign tax credit limitation
purposes if the dividend income is separated from other income items for
purposes of calculating the holder's foreign tax credit.
 
    TAXATION OF CAPITAL GAINS
 
    Upon a sale or other disposition of Vodafone AirTouch shares, a U.S. holder
will recognize gain or loss for U.S. federal income tax purposes in an amount
equal to the difference between the U.S. dollar value of the amount realized and
the U.S. holder's tax basis, determined in U.S. dollars, in the Vodafone
AirTouch shares. Gain or loss recognized will be long-term capital gain or loss
with respect to Vodafone AirTouch shares held for more than 12 months at the
time of the sale or other disposition and any gain recognized generally will be
income from sources within the U.S. for foreign tax credit limitation purposes.
A U.S. holder that is liable for both U.S. federal income tax and United Kingdom
tax on a sale or other disposition of Vodafone AirTouch shares should consult
with his or her tax advisor to determine the U.S. holder's entitlement to credit
the United Kingdom tax against the U.S. holder's United States federal income
tax liability.
 
    BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    The relevant paying agents for the Vodafone AirTouch shares must comply with
information reporting requirements in connection with dividend payments or other
taxable distributions made with respect to Vodafone AirTouch shares within the
U.S. to a non-corporate United States person. In addition, "backup withholding"
at the rate of 31% will apply to these payments unless the holder or beneficial
owner provides an accurate taxpayer identification number in the manner required
by U.S. law and applicable regulations, certifies that the holder or beneficial
owner is not subject to backup withholding, and the holder or beneficial owner
otherwise complies with applicable requirements of the backup withholding rules.
 
    Payment of the proceeds from the sale of Vodafone AirTouch shares to or
through a U.S. office of a broker is subject to both U.S. backup withholding and
information reporting requirements, unless the holder or beneficial owner
certifies its non-U.S. status under penalties of perjury or otherwise
establishes an exemption as described in the preceding paragraph. In general,
neither U.S. backup withholding nor information reporting will apply to a
payment made outside the United States of the proceeds of a sale of Vodafone
AirTouch shares through an office outside the United States of a non-U.S.
broker. Special rules may require information reporting in the case of payments
made outside the U.S. of the proceeds of the sale of Vodafone AirTouch shares
through a U.S. broker.
 
    Amounts withheld under the backup withholding rules may be credited against
a U.S. holder's United States federal income tax liability, and a holder may
obtain a refund of any excess amounts withheld under the backup withholding
rules by filing the appropriate claim for refund with the IRS.
 
QUALIFICATIONS
 
    As noted above, the foregoing discussion does not address all aspects of
U.S. federal income taxation or United Kingdom taxation that may be relevant to
all AirTouch stockholders in light of their particular circumstances. For
instance, the discussion does not address all aspects of U.S. federal income
taxation or United Kingdom taxation to stockholders that are resident, or, in
the case of an individual stockholder, ordinarily resident, in the United
Kingdom, stockholders who conduct a trade or business in the United Kingdom
through a permanent establishment situated therein, or who perform independent
personal services from a fixed base situated therein, and, in either case, to
which holding of AirTouch stock is effectively connected.
 
    In addition, the foregoing discussion does not address all aspects of U.S.
federal income taxation or United Kingdom taxation that may be relevant to
stockholders who are subject to special provisions
 
                                       70
<PAGE>
of U.S. federal income tax law. For example, the discussion does not address all
aspects of U.S. federal income taxation or United Kingdom taxation that may be
relevant to:
 
    - stockholders liable for alternative minimum tax,
 
    - stockholders that actually or constructively will own 10% or more by vote
      and value of the outstanding stock of Vodafone,
 
    - stockholders that hold their stock as part of a straddle, hedge, synthetic
      security, conversion transaction or other integrated investment composed
      of AirTouch shares and one or more other investments,
 
    - stockholders whose "functional currency" is not the U.S. dollar,
 
    - financial institutions,
 
    - insurance companies,
 
    - tax-exempt organizations,
 
    - traders in securities that elect mark-to-market accounting treatment, or
 
    - broker-dealers.
 
    Further, this discussion does not address the U.S. federal income tax
consequences of the merger or the internal reorganization to holders of AirTouch
Class D or Class E preferred stock, or U.S. state or local taxation or taxation
by countries other than the United States and the United Kingdom.
 
    The foregoing discussion is based on existing U.S. federal income and U.K.
tax law, including legislation, administrative rulings and court decisions, as
well as on the U.K.-U.S. tax treaty, all as in effect on the date of this proxy
statement/prospectus, all of which are subject to change, or changes in
interpretation, possibly with retroactive effect. In particular, the United
States and the United Kingdom have entered into negotiations of a new U.K.-U.S.
income tax treaty. The foregoing discussion is further based, in part, upon the
representations of the depositary and the assumption that each obligation in the
deposit agreement relating to Vodafone AirTouch ADSs and any related agreement
will be performed in accordance with its terms.
 
    Finally, Vodafone believes that it is not a "passive foreign investment
company" for U.S. federal income tax purposes within the meaning of Section
1297(a) of the U.S. tax code and the foregoing discussion so assumes.
 
    EACH AIRTOUCH STOCKHOLDER IS ADVISED TO CONSULT HIS OR HER OWN TAX ADVISOR
AS TO THE U.S. FEDERAL INCOME TAX CONSEQUENCES AND UNITED KINGDOM TAX
CONSEQUENCES OF THE MERGER, THE INTERNAL REORGANIZATION, AND THE OWNERSHIP AND
DISPOSITION OF THE VODAFONE AIRTOUCH SHARES TO HIM OR HER, IN EACH CASE IN LIGHT

U.S. ESTATE, GIFT, STATE, LOCAL OR NON-U.S. AND NON-UNITED KINGDOM TAX
CONSEQUENCES OF THE MERGER AND THE INTERNAL REORGANIZATION.
 
UNITED KINGDOM TAX CONSEQUENCES OF THE OWNERSHIP OF VODAFONE AIRTOUCH ORDINARY
SHARES AND VODAFONE AIRTOUCH ADSS
 
    TAXATION OF DISTRIBUTIONS
 
    A U.S. holder who receives a dividend from Vodafone AirTouch will not have
any further U.K. tax to pay in respect of the dividend but will not be able to
claim any payment in respect of the dividend under the U.K.-U.S. tax treaty. See
"United States Federal Income Tax Consequences of the Ownership of Vodafone
AirTouch Ordinary Shares and Vodafone AirTouch ADSs--Taxation of Dividends."
 
    TAXATION OF CAPITAL GAINS
 
    A U.S. holder who is neither resident nor ordinarily resident for tax
purposes in the U.K. will not normally be liable for U.K. tax on capital gains
realized on the disposal of Vodafone AirTouch ordinary
 
                                       71
<PAGE>
shares or Vodafone AirTouch ADSs. However, this will not apply if at the time of
the disposal, the U.S. holder carries on a trade, which for this purpose
includes a profession or vocation, in the U.K. through a branch or agency and
the disposed Vodafone AirTouch ordinary shares or Vodafone AirTouch ADSs are or
have been used in or for the purposes of that trade or are or have been used or
held by or for the purposes of the branch or agency. An individual U.S. holder
who is only temporarily not resident in the U.K. may, under anti-avoidance
legislation, still be liable for U.K. tax on capital gains realized, subject to
any available exemption or relief.
 
    INHERITANCE AND GIFT TAXES
 
    Vodafone AirTouch ordinary shares and Vodafone AirTouch ADSs are assets
situated in the U.K. for the purposes of U.K. inheritance tax. A gift of these
assets by, or the death of, an individual holder may, subject to certain
exemptions and reliefs, give rise to a liability to U.K. inheritance tax even if
the holder is neither domiciled in the U.K. nor deemed to be domiciled there
under special rules relating to long residence or previous domicile. For U.K.
inheritance tax purposes, a transfer of assets at less than full market value
may be treated as a gift and particular rules apply to gifts where the donor
reserves or retains some benefit. Special rules also apply to close companies
and to trustees of settlements holding Vodafone AirTouch ordinary shares or
Vodafone AirTouch ADSs, bringing them within the charge to inheritance tax. An
individual who is domiciled in the U.S. for the purposes of the U.K.-U.S. estate
and gift tax convention and who is not a national of the U.K. for the purposes
of the U.K.-U.S. estate and gift tax convention will generally not be subject to
U.K. inheritance tax in respect of the Vodafone AirTouch ordinary shares or
Vodafone AirTouch ADSs on the individual's death or on a gift of the Vodafone
AirTouch ordinary shares or Vodafone AirTouch ADSs during the individual's
lifetime, provided that any applicable U.S. federal gift or estate tax liability
is paid, unless the Vodafone AirTouch ordinary shares or Vodafone AirTouch ADSs
are part of the business property of a permanent establishment of an enterprise
of the individual in the U.K. or pertain to a fixed base in the U.K. of the
individual used for the performance of independent personal services. Where a
settlor who, at the time of settlement, was a U.S. holder has placed Vodafone
AirTouch ordinary shares or Vodafone AirTouch ADSs in trust, the Vodafone
AirTouch ordinary shares or Vodafone AirTouch ADSs will generally not be subject
to U.K. inheritance tax if the settlor, at the time of settlement, was domiciled
in the U.S. for the purposes of the U.K.-U.S. estate and gift tax convention and
was not a U.K. national, provided that the Vodafone AirTouch ordinary shares or
Vodafone AirTouch ADSs are not part of the business property of a permanent
establishment in the U.K. and do not pertain to a fixed base in the U.K., as
more fully summarized above.
 
    In the exceptional case where the Vodafone AirTouch ordinary shares or
Vodafone AirTouch ADSs are subject both to U.K. inheritance tax and to U.S.
federal gift or estate tax, the estate and gift tax convention generally
provides for the tax paid in the U.K. to be credited against tax paid in the
U.S. or for tax paid in the U.S. to be credited against tax payable in the U.K.
based on priority rules set out in the estate and gift tax convention.
 
    STAMP DUTY AND STAMP DUTY RESERVE TAX
 
    Vodafone and AirTouch will be jointly and severally liable for all stamp
duties, stamp duty reserve tax and similar taxes and governmental levies imposed
in connection with the issuance or creation of the Vodafone AirTouch ordinary
shares constituting the stock consideration and any Vodafone AirTouch ADSs in
connection therewith and any U.K. stamp duty, stamp duty reserve tax or similar
governmental charge, or any interest or penalties thereon, that may be payable
by Vodafone, AirTouch or, after the merger, Vodafone AirTouch pursuant to the
deposit agreement relating to the ADSs. See "DESCRIPTION OF VODAFONE AIRTOUCH
AMERICAN DEPOSITARY SHARES--Payment of Taxes."
 
    No stamp duty will be payable on the acquisition or transfer of Vodafone
AirTouch ADSs or beneficial ownership of Vodafone AirTouch ADSs, provided that
any instrument of transfer is not
 
                                       72
<PAGE>
executed in the U.K. and provided further that the instrument of transfer is not
brought into the U.K. An agreement for the transfer of Vodafone AirTouch ADSs or
beneficial ownership of Vodafone AirTouch ADSs will not give rise to a liability
for stamp duty reserve tax.
 
    A transfer for value of the Vodafone AirTouch ordinary shares will generally
be subject to AD VALOREM stamp duty or to stamp duty reserve tax. Stamp duty
will arise on the execution of an instrument to transfer Vodafone AirTouch
ordinary shares. Stamp duty reserve tax will arise on the entry into an
agreement to transfer Vodafone AirTouch ordinary shares but the charge may be
canceled if stamp duty has been paid. Stamp duty and stamp duty reserve tax are
normally a liability of the purchaser. Any transfer for value of the underlying
Vodafone AirTouch ordinary shares represented by Vodafone AirTouch ADSs may give
rise to a liability on the transferee to U.K. stamp duty or stamp duty reserve
tax. The rate of stamp duty payable is 50p per L100, or part of L100, and 0.5%
of the consideration in the case of stamp duty reserve tax. On a transfer of
Vodafone AirTouch ordinary shares from the custodian of the depositary to a
holder of a Vodafone AirTouch ADS upon cancellation of the Vodafone AirTouch
ADS, only a fixed stamp duty of 50p per instrument of transfer is currently
payable. However, the U.K. government has announced that it intends to increase
this fixed duty to L5 and to require the rounding up of AD VALOREM stamp duty to
the next multiple of L5 (if the duty is not already a multiple of L5), effective
October 1, 1999.

                              THE MERGER AGREEMENT
 
    The following description of the merger agreement describes the material
terms of the agreement but does not purport to describe all the terms of the
agreement. The complete text of the merger agreement is attached to this proxy
statement/prospectus as Appendix A and is incorporated by reference herein. All
shareholders are urged to read the merger agreement in its entirety because it
is the legal document that governs the merger.
 
THE MERGER
 
    Pursuant to the merger agreement, Apollo Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Vodafone, will merge into AirTouch,
with AirTouch surviving as a subsidiary of Vodafone.
 
    The merger will become effective when Vodafone and AirTouch file the
certificate of merger with the Secretary of State of the State of Delaware or at
a later time if so specified in the certificate of merger. The merger is
expected to become effective on the same day as the closing of the merger, which
will take place either as soon as practicable after the conditions described in
the merger agreement have been satisfied or waived or on another date agreed
upon by Vodafone and AirTouch.
 
THE INTERNAL REORGANIZATION
 
    Before the Vodafone/AirTouch merger takes place, AirTouch will cause the
internal reorganization to occur, in which
 
    - AirTouch Merger Sub, Inc., a newly-formed Delaware corporation and a
      wholly owned subsidiary of AirTouch, will merge into AirTouch, with
      AirTouch being the surviving corporation, and
 
    - amendments will be made to the certificates of designation of the AirTouch
      Class C, Class D and Class E preferred stock.
 
    For more details on the effects of the internal reorganization, see "THE
INTERNAL REORGANIZATION" beginning on page 59.
 
CONSIDERATION TO BE RECEIVED IN THE MERGER
 
    At the time the merger becomes effective:
 
    - each share of AirTouch common stock outstanding, except for the shares
      owned by Vodafone, AirTouch, or any of their subsidiaries or any holder
      who properly exercises his appraisal rights, will be converted into
 
      (1) five (5) Vodafone AirTouch ordinary shares, which will be delivered in
          the form of 0.5 of a Vodafone AirTouch ADS, and
 
      (2) $9.00 in cash, without interest.
 
    - each share of AirTouch owned by Vodafone, AirTouch, or any of their
      subsidiaries will automatically be canceled without the payment of any
      consideration;
 
    - each AirTouch option outstanding and unexercised will be converted into
      the specific rights described on page 79 under "--Stock Options and Other
      Employee Benefits;"
 
    - each share of common stock of Apollo Merger Sub outstanding will be
      canceled; and
 
    - AirTouch will issue to Vodafone the number of shares of AirTouch common
      stock equal to the number of shares of AirTouch common stock converted in
      the merger.
 
TREATMENT OF PREFERRED STOCK
 
    Immediately prior to the merger, according to the Class B certificate of
designation
 
                                       74
<PAGE>
    - each outstanding share of AirTouch Class B preferred stock will convert
      automatically into AirTouch common stock at the exchange ratio set forth
      in the Class B certificate of designation, which is 0.806 shares of
      AirTouch common stock per share of AirTouch Class B preferred stock,
      subject to anti-dilution adjustments, and
 
    - all dividends accrued through the date of conversion and unpaid on the
      shares of AirTouch Class B preferred stock, other than previously declared
      dividends payable to the holder of record on a prior date, whether or not
      declared, will be due and payable in cash out of funds of AirTouch after
      the internal reorganization.
 
    The shares of AirTouch common stock issuable upon conversion of the Class B
preferred stock will then be converted into and canceled in exchange for
Vodafone AirTouch ADSs and cash as described above in "--Consideration to Be
Received in the Merger."
 
    Each share of Class C preferred stock of AirTouch outstanding immediately
prior to the merger will remain outstanding as a share of Class C preferred
stock of AirTouch after the merger. Each share of AirTouch Class C preferred
stock will, after the merger, be subject to conversion or redemption, at the
election of the holder of the AirTouch Class C preferred stock, in accordance
with the terms set forth in Section 4(e) of the Class C certificate of
designation. According to their terms, the shares of Class C preferred stock are
expected to be redeemable beginning on September 20, 1999 for the merger
consideration that such holder would have received had he held that number of
shares of AirTouch common stock issuable upon a redemption of his AirTouch Class
C preferred stock immediately prior to the merger. After the merger, each share
of Class C preferred stock will be convertible into the merger consideration
that would have been received by a holder of 1.379 shares of AirTouch common
stock.
 
    Each share of Class D and Class E preferred stock of AirTouch outstanding
immediately prior to the merger, other than shares owned by any holder who
properly exercises his appraisal rights, will remain outstanding as a share of
AirTouch Class D preferred stock or AirTouch Class E preferred stock,
respectively, after the merger.
 
EXCHANGE OF AIRTOUCH COMMON STOCK
 
    Vodafone has appointed Equiserve Limited Partnership as the exchange agent
who will exchange certificates which, before the merger, represent outstanding
shares of AirTouch common stock and, in the merger, will be converted into the
right to receive Vodafone AirTouch ADSs, and the cash consideration. Promptly
after the merger takes place, AirTouch or the exchange agent will mail to each
record holder of AirTouch common stock holding a certificate a letter of
transmittal for use in effecting delivery of the AirTouch common stock to the
exchange agent.
 
    Vodafone will issue the Vodafone AirTouch ordinary shares as the stock
consideration in registered form to Equiserve Limited Partnership as nominee and
agent for the record holders. If the redenomination of the Vodafone ordinary
share capital takes effect immediately prior to the merger, then, unless the
directors of Vodafone determine not to issue bearer shares, Vodafone will
 
    (1) strike the name of the nominee from the Vodafone shareholders' register,
 
    (2) create bearer shares with respect to the Vodafone ordinary shares; and
 
    (3) deliver the bearer shares to the nominee for delivery to the depositary
in order for it to issue the Vodafone AirTouch ADSs to holders of AirTouch
common stock.
 
    The fact that the Vodafone AirTouch ordinary shares underlying the Vodafone
AirTouch ADSs may be evidenced by bearer shares will not affect the rights of
Vodafone AirTouch ADS holders to receive Vodafone AirTouch ordinary shares
registered in their name upon any withdrawal of those shares in accordance with
the terms of the deposit agreement governing the rights of Vodafone AirTouch
ADSs. Holders of AirTouch common stock will not be liable for any charges in
connection
 
                                       75
<PAGE>
with the receipt of Vodafone AirTouch ADSs representing bearer shares. See
"DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY SHARES."
 
    Vodafone AirTouch ordinary shares issued in connection with the merger which
are in registered form will be registered in the name of The Bank of New York,
as depositary. Vodafone AirTouch ordinary shares issued in connection with the
merger which are bearer shares will be held by The Bank of New York or its
nominee. In addition, Vodafone will periodically deposit cash in an amount
sufficient to provide the exchange agent with funds to make the cash payments
required to be made under the merger agreement.
 
    After delivering AirTouch certificates and a signed transmittal letter to
the exchange agent or, in the case of AirTouch common stock held through the
AirTouch Direct Purchase and Sale Plan program or through The Depository Trust
Company, without further action by the holder, each holder of AirTouch common
stock will be entitled to receive in exchange for the AirTouch certificates:
 
    - the number of Vodafone AirTouch ADSs that the holder has the right to
      receive as stock consideration, and
 
    - a check in the amount, after giving effect to any required tax
      withholdings, of
 
         (1) the cash consideration that the holder has the right to receive,
 
         (2) cash in lieu of fractional Vodafone AirTouch ADSs on the terms
             described below plus
 
         (3) any cash dividends or other distributions that the holder has the
             right to receive, including dividends or distributions payable with
             respect to the holder's Vodafone AirTouch ADSs with a record date
             after the merger and a payment date on or prior to the date of the
             surrender and not previously paid.
 
    AirTouch certificates that are surrendered will be canceled. No interest
will be paid or accrued on any amount payable upon surrender of the share
certificates. No holder of an unsurrendered AirTouch certificate will receive
any dividends or other distributions with respect to Vodafone AirTouch ADSs to
which it is entitled under the merger agreement until the AirTouch certificate
registered to the holder is surrendered to the exchange agent.
 
    The depositary will not issue fractional ADSs in connection with the merger.
Instead, each holder of shares of AirTouch common stock exchanged in the merger
who would otherwise have received a fraction of a Vodafone AirTouch ADS will
receive cash, without interest, in an amount equal to the holder's proportionate
interest in the net proceeds from the sale on the NYSE by the exchange agent on
behalf of all holders of all fractional Vodafone AirTouch ADSs that the
depositary would otherwise issue in the merger. Vodafone will pay all
commissions, transfer taxes and out-of-pocket costs, including the expenses and
compensation of the exchange agent, incurred in connection with the sale of
fractional Vodafone AirTouch ADSs.
 
    In order for a person who is not a registered holder of the AirTouch common
stock represented by an AirTouch certificate to have that certificate exchanged
under the merger, he must
 
    - ensure that the certificate surrendered is properly endorsed and in proper
      form for transfer and
 
    - pay the exchange agent any transfer or other taxes required or establish
      to the satisfaction of the exchange agent that all taxes have been paid or
      are not payable.
 
REPRESENTATIONS AND WARRANTIES
 
    The merger agreement contains a number of customary representations and
warranties made by Vodafone and AirTouch regarding, among other things, due
organization, good standing and qualification; capital structure; corporate
authority to enter into the contemplated transactions and lack of conflicts with
corporate governance documents; governmental filings; reports and financial
statements; absence of certain changes or events; litigation and liabilities;
brokers or finders; ownership of the other party's common stock; assets;
licenses; intellectual property; year 2000 compliance; joint
 
                                       76
<PAGE>
ventures and tax matters. AirTouch has also represented that it has taken or
will take all actions appropriate and necessary to ensure that provisions of the
Delaware General Corporation Law limiting business combinations will not affect
the merger or any other transaction contemplated by the merger agreement and
that neither Vodafone nor AirTouch will have any obligations under AirTouch's
stockholder rights plan and that the holders of those rights will not have any
rights under the stockholder rights plan.
 
    The merger agreement also contains customary representations and warranties
of Vodafone regarding Apollo Merger Sub, Inc., including its corporate authority
to enter into the contemplated transactions and absence of previous business
activities.
 
CONDUCT OF BUSINESS PENDING THE MERGER; OTHER ACTIONS
 
    During the period from the signing of the merger agreement until the merger
becomes effective, each of Vodafone and AirTouch has agreed as to itself and its
subsidiaries, unless the other party approves otherwise in writing, among other
things, that:
 
    - they will carry on their businesses in the ordinary course and, to the
      extent practicable, will preserve its and their business organization
      intact and maintain their licenses in force and maintain their existing
      relations and goodwill with customers, suppliers, creditors, regulators,
      lessors, employees and business associates, and
 
    - they will not make any decision or commitment regarding a significant
      investment or divestment except in the ordinary course of business or
      under financial plans previously communicated to the other party, without
      first consulting with the other party.
 
    In addition, Vodafone and AirTouch have agreed that before the merger they
will not take any of the following actions outside of the parameters specified
in the merger agreement:
 
    - declare and pay dividends or change their share capital other than, among
      other things, the redenomination of ordinary share capital in the case of
      Vodafone,
 
    - issue securities,
 
    - amend their corporate governance documents,
 
    - incur significant debt outside the ordinary course of business, and
 
    - modify their benefit plans and compensation of directors, officers and
      employees outside of the ordinary course of business.
 
    In addition, Vodafone and AirTouch have each agreed:
 
    - to use reasonable best efforts to cause the merger to constitute a
      reorganization under Section 368(a) of the U.S. tax code;
 
    - to timely satisfy all applicable tax reporting and filing requirements
      contained in the U.S. tax code with respect to the merger;
 
    - to cooperate with the other between the date of the merger agreement and
      the closing date, and to use reasonable efforts, to ensure that the merger
      satisifies the 50% substantiality tax test under the U.S. tax code; and
 
    - to cooperate with the other between the date of the merger agreement and
      the closing date, and to use its reasonable efforts, to obtain from the
      IRS the private letter ruling with respect to the merger as described in
      United States Treasury regulations Section 1.367(a)-3(c)(9), and to
      prepare jointly the ruling request and any communications with the IRS.
      The private letter ruling was obtained on April 12, 1999.
 
    AirTouch must also use its best efforts to cause each person who may be
considered an affiliate of AirTouch under Rule 145 of the Securities Act to
execute an agreement restricting the disposition of the affiliate's Vodafone
AirTouch ADSs received in the merger or underlying Vodafone AirTouch
 
                                       77
<PAGE>
ordinary shares. Neither Vodafone AirTouch nor the depositary will register any
transfers of Vodafone AirTouch ordinary shares or Vodafone AirTouch ADSs by any
person who may be considered an affiliate unless the transfer is in compliance
with these restrictions.
 
ACQUISITION PROPOSALS
 
    Vodafone and AirTouch each has agreed that neither it nor any of its
subsidiaries nor any of the officers and directors of it or its subsidiaries
will, and that it will direct and use its best reasonable efforts to cause its
or its subsidiaries' employees, agents and representatives not to
 
    - solicit, encourage or facilitate any inquiries with respect to any
      acquisition proposal, including a merger, reorganization, share exchange,
      dual-holding company transaction, consolidation, or similar transaction
      involving it or any purchase of all or any significant portion of its
      equity securities or of its and its subsidiaries' assets taken as a whole;
      or
 
    - have any discussions with or provide any confidential information or data
      to any person relating to, or engage in any negotiations concerning, an
      acquisition proposal, or otherwise facilitate any effort or attempt to
      make or implement an acquisition proposal.
 
However, each of Vodafone, AirTouch and their respective boards of directors has
the right to
 
    - make any disclosure to its shareholders if, in the good faith judgment of
      its board of directors, failure to do so would be inconsistent with its
      obligations under applicable law;
 
    - negotiate with or furnish information to any person who has made a bona
      fide written acquisition proposal that is a superior proposal, as
      described below, and that did not result from the breach of the party's
      obligations not to solicit or engage in discussions or negotiations with
      respect to an acquisition proposal (as described above); or
 
    - recommend an acquisition proposal to its shareholders if the acquisition
      proposal is a superior proposal.
 
    A superior proposal is an acquisition proposal by a third party
 
    - on terms which the board of directors of Vodafone or AirTouch, as the case
      may be, determines in good faith after consultation with its financial
      advisors, whose advice will be communicated to the other party, to be more
      favorable from a financial point of view to its shareholders than the
      merger, after giving the other party at least five business days to
      respond to the acquisition proposal and
 
    - which the board of directors of Vodafone or AirTouch, as the case may be,
      determines in good faith is reasonably likely to be consummated on the
      terms set forth, taking into account all legal, financial, regulatory and
      other aspects of the proposal.

STOCK OPTIONS AND OTHER EMPLOYEE BENEFITS
 
    In the merger, all outstanding and unexercised AirTouch stock options and
tandem stock appreciation rights, whether vested or unvested, will
 
    - be assumed by Vodafone AirTouch,
 
    - cease to represent a right to acquire shares of AirTouch common stock and
 
    - be converted automatically into options to purchase, and tandem stock
      appreciation rights with respect to, Vodafone AirTouch ordinary shares or
      Vodafone AirTouch ADSs.
 
    Each option and tandem stock appreciation right will remain subject to the
terms of the AirTouch stock plan under which it was issued and the agreement
evidencing its grant, except that after the merger
 
    - the number of Vodafone AirTouch ordinary shares, or Vodafone AirTouch
      ADSs, as applicable, purchasable upon exercise of each option or subject
      to a tandem stock appreciation right will be equal to the number of shares
      of AirTouch common stock that were purchasable under the option or subject
      to the tandem stock appreciation right immediately prior to the merger
      multiplied by the exchange ratio or, in the case of Vodafone AirTouch
      ADSs, one-tenth of the exchange ratio, in each case subject to any
      rounding as provided for in the merger agreement, and
 
    - the exercise price per Vodafone AirTouch ordinary share or, Vodafone
      AirTouch ADSs, as applicable, under each option or tandem stock
      appreciation right will be obtained by dividing
 
       (1) the per share exercise price of each option or tandem stock
           appreciation right less the per share cash consideration by
 
       (2) the exchange ratio or, in the case of Vodafone AirTouch ADSs,
           one-tenth of the exchange ratio, in each case subject to any rounding
           as provided for in the merger agreement.
 
    Notwithstanding the foregoing, the number of Vodafone AirTouch ordinary
shares and the exercise price per Vodafone AirTouch ordinary share of each
AirTouch stock option that is intended to be an "incentive stock option," as
defined in section 422 of the U.S. tax code, will be adjusted as required by
Section 424 of the U.S. tax code. Vodafone AirTouch ordinary shares to be issued
upon the exercise of AirTouch stock options may, at the election of the holders
of AirTouch stock options, be delivered in the form of Vodafone AirTouch ADSs.
AirTouch has agreed that it will make all necessary arrangements with respect to
the AirTouch stock plans to permit the assumption by Vodafone of any unexercised
AirTouch stock options and tandem stock appreciation rights.
 
    Vodafone and its subsidiaries intend to provide current and former employees
and directors of AirTouch compensation and benefit programs, including annual
and long-term incentive programs, that are competitive with those provided by
large industrial companies in the U.S. and U.K. Specifically, Vodafone AirTouch
will, and will cause its subsidiaries to
 
    - keep in effect for one year after the merger, without any change to the
      eligibility provisions and levels of benefits, the AirTouch compensation
      and benefit plans in effect on the date of the merger agreement;
 
    - recognize an employee's service prior to the merger with AirTouch, its
      subsidiaries and any of their predecessor entities for all purposes,
      including eligibility to participate, vesting, benefit accrual,
      eligibility to commence benefits and severance, under any benefits plans
      of Vodafone AirTouch or its subsidiaries in which the employee
      participates, provided that this recognition of service does not result in
      any duplication of benefits;
 
    - recognize any appropriate out-of-pocket expenses of each employee of
      AirTouch or its subsidiaries for purposes of determining the employee's
      deductible and copayment expenses under any benefit plans of Vodafone
      AirTouch;
 
                                       79
<PAGE>
    - waive any provisions under the benefit plans of Vodafone AirTouch which
      restrict benefits by reason of pre-existing conditions; and
 
    - honor the terms of each outstanding employment, change of control,
      severance and termination agreement between AirTouch or its subsidiaries
      and their directors, officers or employees, including all obligations
      pertaining to bonus deferral plans, vested and accrued benefits and
      similar employment and benefit arrangements.
 
INDEMNIFICATION AND INSURANCE
 
    After the merger, Vodafone AirTouch will indemnify the directors and
officers of AirTouch and its subsidiaries for any losses they incur because they
acted as directors and officers of AirTouch or its subsidiaries before the
merger, as follows:
 
    - Vodafone AirTouch will maintain all rights to indemnification and all
      limitations on liability existing under the AirTouch certificate of
      incorporation and the AirTouch by-laws in favor of those directors and
      officers of AirTouch;
 
    - Vodafone AirTouch will maintain all rights to indemnification and all
      limitations on liability existing under any agreement between any of those
      directors or officers and AirTouch or its subsidiaries;
 
    - Vodafone AirTouch will, for a period of six years after the merger becomes
      effective, indemnify those directors and officers to the same extent they
      are indemnified on the date of the merger agreement; and
 
    - Vodafone AirTouch will, for a period of six years after the merger becomes
      effective, provide liability insurance for those directors and officers
      for acts or omissions occurring before the effective time of the merger on
      terms at least as favorable as those of any policy presently in effect.
      However, during the six-year period, Vodafone AirTouch will not be
      required to provide any more coverage than can be obtained for the
      remainder of the period for an annual premium costing more than 150% of
      the annual premium currently paid by AirTouch for its existing coverage.
 
DIRECTORS AND MANAGEMENT OF VODAFONE AIRTOUCH FOLLOWING THE MERGER
 
    Following the merger, the board of directors of Vodafone AirTouch will
consist of 14 persons, seven of whom Vodafone will designate, of whom three will
be non-executive directors, and seven of whom AirTouch will designate, of whom
five will be non-executive directors. These AirTouch director-designates, whose

AMENDMENT; WAIVER
 
    Vodafone and AirTouch may amend the merger agreement by written agreement
prior to completion of the merger, but, after AirTouch's stockholders or
Vodafone's shareholders have approved the merger agreement, no amendment may be
made which by law requires further stockholder approval without the stockholder
approval being obtained.
 
    Any provision of the merger agreement may be waived prior to the merger
being completed, but only if the waiver is in writing and signed by the party
against whom the waiver is to be effective.

                                APPRAISAL RIGHTS
 
    Holders of AirTouch common stock can decide to receive, instead of having
their shares converted into the merger consideration, and holders of AirTouch
Class D and Class E preferred stock can decide to receive, instead of keeping
their shares after the merger, an amount which the Court of Chancery of the
State of Delaware decides is the "fair value" of their AirTouch common stock,
AirTouch Class D preferred stock or AirTouch Class E preferred stock, as the
case may be, exclusive of any element of value arising from the accomplishment
or expectation of the merger, together with a fair rate of interest, as
determined by the court.
 
    In addition, holders of AirTouch Class D preferred stock and AirTouch Class
E preferred stock can decide to receive, instead of having their shares
converted in the internal reorganization into shares of Class D preferred stock
of AirTouch as the surviving corporation in the internal reorganization or
shares of Class E preferred stock of AirTouch as the surviving corporation in
the internal reorganization, as the case may be, an amount determined in a
similar fashion.
 
    These rights are known as "appraisal rights." If a holder of AirTouch common
stock wishes to exercise appraisal rights in connection with the merger, the
holder must not vote in favor of the merger and must meet the conditions
described below. If a holder of AirTouch Class D preferred stock or AirTouch
Class E preferred stock wishes to exercise appraisal rights with respect to the
internal reorganization or the merger, the holder must meet the conditions
described below.
 
    Holders of AirTouch Class B and Class C preferred stock are not entitled to
appraisal rights under Delaware law in connection with the merger or the
internal reorganization. However, holders of AirTouch Class B and Class C
preferred stock who converted their shares into AirTouch common stock prior to
the record date for the special meeting are entitled to assert appraisal rights
in connection with the merger with respect to their shares of AirTouch common
stock.
 
    The conditions necessary to secure appraisal rights are set out in full in
Appendix F. This summary is not meant to be a complete statement on appraisal
rights, but rather is only a guide for a stockholder who wishes to exercise
appraisal rights. Delaware law requires that AirTouch notify stockholders at
least 20 days prior to the special meeting of AirTouch stockholders that they
have a right of appraisal and provide stockholders with a copy of Section 262 of
the DGCL. This proxy statement/prospectus constitutes that notice. If AirTouch
stockholders do not follow the procedures set out below and in Appendix F, they
will lose their appraisal rights.
 
    ALL REFERENCES IN THIS SUMMARY AND IN SECTION 262 TO A "STOCKHOLDER" OR TO A
"HOLDER" OF AIRTOUCH STOCK ARE TO THE RECORD HOLDERS OF THE AIRTOUCH STOCK AS TO
WHICH APPRAISAL RIGHTS ARE AVAILABLE. A PERSON HAVING A BENEFICIAL INTEREST IN
SHARES OF AIRTOUCH STOCK HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A
BROKER OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW THE
STEPS SUMMARIZED BELOW PROPERLY AND IN A TIMELY MANNER TO PERFECT THE HOLDER'S
APPRAISAL RIGHTS.
 
    A holder of AirTouch common stock wishing to exercise his appraisal rights
with respect to the merger must deliver, before the vote on the merger at the
special meeting, a written demand for appraisal of the holder's shares.
 
    A holder of AirTouch common stock wishing to exercise his appraisal rights
with respect to the merger must not vote in favor of adoption of the merger
agreement. Because a duly executed proxy which does not contain voting
instructions will, unless revoked, be voted for the merger, a holder of AirTouch
common stock who votes by proxy and who wishes to exercise appraisal rights must
vote against the merger or abstain from voting on the merger. A vote against the
merger, in person or by proxy, will not in and of itself constitute a written
demand for appraisal satisfying the requirements of Section 262, and a separate
written demand for appraisal is required.
 
                                       87
<PAGE>
    A holder of AirTouch Class D or Class E preferred stock wishing to exercise
appraisal rights with respect to the merger or the internal reorganization must
deliver, before the vote on the merger or the internal reorganization, as the
case may be, at the special meeting, a written demand for appraisal of the
holder's shares.
 
    In addition, a holder of AirTouch common stock, AirTouch Class D preferred
stock or AirTouch Class E preferred stock wishing to exercise appraisal rights
in connection with the merger or the internal reorganization, as the case may
be, must be the record holder of his shares on the date the holder makes the
written demand for appraisal and must continue to hold the shares of record
until the completion of the merger or the internal reorganization, as the case
may be.
 
    A demand for appraisal should be executed by or on behalf of the holder of
record, fully and correctly, as the holder's name appears on the stock
certificates. The demand must also state that the stockholder intends to demand
appraisal of the holder's shares of AirTouch common stock, AirTouch Class D
preferred stock or AirTouch Class E preferred stock in connection with the
merger or the internal reorganization, as the case may be.
 
    If the shares are owned of record in a fiduciary capacity, including by a
trustee, guardian or custodian, the demand should be executed in that capacity,
and if the shares are owned of record by more than one person, as in a joint
tenancy and tenancy in common, the demand should be executed by or on behalf of
all joint owners. An authorized agent, including two or more joint owners, may
execute a demand for appraisal on behalf of a holder of record but the agent
must identify the record owner or owners and expressly disclose the fact that,
in executing the demand, the agent is agent for the owner or owners.
 
    A record holder such as a broker who holds AirTouch common stock, AirTouch
Class D preferred stock or AirTouch Class E preferred stock as nominee for
several beneficial owners may exercise appraisal rights with respect to the
shares held for one or more beneficial owners while not exercising these rights
with respect to the shares held for other beneficial owners; in this
circumstance, however, the written demand should set forth the number of shares
as to which appraisal is sought and, where no number of shares is expressly
mentioned, the demand will be presumed to cover all shares of AirTouch common
stock, AirTouch Class D preferred stock or AirTouch Class E preferred stock held
in the name of the record owner. Holders who hold their AirTouch common stock,
AirTouch Class D preferred stock or AirTouch Class E preferred stock in
brokerage accounts or other nominee forms and who wish to exercise appraisal
rights are urged to consult with their brokers to determine the appropriate
procedures for the making of a demand for appraisal by the nominee.
 
    HOLDERS OF AIRTOUCH COMMON STOCK, AIRTOUCH CLASS D PREFERRED STOCK OR
AIRTOUCH CLASS E PREFERRED STOCK MUST SEND ALL WRITTEN DEMANDS FOR APPRAISAL
UNDER SECTION 262 TO AIRTOUCH COMMUNICATIONS, INC., ONE CALIFORNIA STREET, SAN
FRANCISCO, CA 94111, ATTENTION: MARGARET G. GILL, SENIOR VICE PRESIDENT, LEGAL,
EXTERNAL AFFAIRS AND SECRETARY. AIRTOUCH MUST RECEIVE WRITTEN DEMANDS FOR
APPRAISAL UNDER SECTION 262 BEFORE THE MERGER AND THE INTERNAL REORGANIZATION
ARE VOTED UPON AT THE SPECIAL MEETING.
 
    Within ten days after the date the merger becomes effective, AirTouch must
notify each holder of AirTouch common stock, AirTouch Class D preferred stock or
AirTouch Class E preferred stock who has complied with Section 262 and, in the
case of a holder of AirTouch common stock, has not voted in favor of the merger
of the date that the merger has become effective.
 
    Within ten days after the date the internal reorganization becomes
effective, AirTouch must notify each holder of AirTouch Class D preferred stock
or AirTouch Class E preferred stock who has complied with Section 262 of the
date that the internal reorganization has become effective.
 
    Within 120 days after the date the merger or the internal reorganization, as
the case may be, becomes effective, but not thereafter, AirTouch or any holder
of AirTouch common stock, AirTouch
 
                                       88
<PAGE>
Class D preferred stock or AirTouch Class E preferred stock who has complied
with Section 262 and is entitled to appraisal rights under Section 262 may file
a petition in the Court of Chancery of the State of Delaware demanding a
determination of the fair value of the holder's shares of AirTouch common stock,
AirTouch Class D preferred stock or AirTouch Class E preferred stock. AirTouch
will have no obligation to file a petition, and neither AirTouch nor Vodafone
has any present intention to cause such a petition to be filed. Accordingly, it
is the obligation of stockholders seeking appraisal rights to initiate all
necessary action to perfect appraisal rights within the time prescribed in
Section 262.
 
    Any holder of AirTouch common stock, AirTouch Class D preferred stock or
AirTouch Class E preferred stock who has complied with the requirements for
exercise of appraisal rights will be entitled, upon written request, to receive
from AirTouch,
 
    (1) in the case of holders of AirTouch common stock, AirTouch Class D
preferred stock or AirTouch Class E preferred stock in connection with the
merger, a statement setting forth the aggregate number of shares of AirTouch
common stock not voted in favor of the merger and the number of shares of
AirTouch Class D preferred stock, AirTouch Class E preferred stock and AirTouch
common stock with respect to which demands for appraisal have been received and
the total number of holders of these shares, and
 
    (2) in the case of holders of AirTouch Class D preferred stock and Class E
preferred stock in connection with the internal reorganization, a statement
setting forth the aggregate number of shares of AirTouch Class D preferred stock
and AirTouch Class E preferred stock with respect to which demands for appraisal
have been received and the total number of holders of these shares.
 
    If a holder of AirTouch common stock, AirTouch Class D preferred stock or
AirTouch Class E preferred stock timely files a petition for an appraisal, the
Court of Chancery is empowered to conduct a hearing on this petition to
determine those holders who have complied with Section 262 and who have become
entitled to appraisal rights thereunder. The Court of Chancery may require the
holders of AirTouch common stock, AirTouch Class D preferred stock or AirTouch
Class E preferred stock who demanded appraisal of their shares to submit their
stock certificates to the Register in Chancery for notation of the pending
appraisal proceeding. If any stockholder fails to comply with its direction, the
Court of Chancery may dismiss the proceedings as to the stockholder.
 
    After determining the holders entitled to appraisal, the Court of Chancery
will appraise the "fair value" of their shares of AirTouch common stock,
AirTouch Class D preferred stock or AirTouch Class E preferred stock, as the
case may be, exclusive of any element of value arising from the accomplishment
or expectation of the merger or the internal reorganization, together with a
fair rate of interest, if any, to be paid upon the amount determined to be the
fair value. Stockholders considering seeking appraisal should be aware that the
fair value of their AirTouch common stock, AirTouch Class D preferred stock or
AirTouch Class E preferred stock, as the case may be, as determined in an
appraisal proceeding under Section 262 could be more than, the same as or less
than the merger consideration they would receive pursuant to the merger or the
internal reorganization, as the case may be, if they did not seek appraisal of
their shares, and that investment banking opinions as to fairness from a
financial point of view are not necessarily opinions as to fair value under
Section 262. The Delaware Supreme Court has stated that "proof of value by any
techniques or methods which are generally considered acceptable in the financial
community and otherwise admissible in court" should be considered in the
appraisal proceeding. In addition, Delaware courts have decided that the
statutory appraisal remedy, depending on factual circumstances, may or may not
be a dissenter's exclusive remedy. The Court of Chancery will also determine the
amount of interest, if any, payable upon the amounts due to persons whose shares
of AirTouch common stock, AirTouch Class D preferred stock or AirTouch Class E
preferred stock have been appraised.
 
    The court may determine the costs of the appraisal action and may allocate
the costs among the parties as the court deems equitable. Each party must bear
its own other expenses of the proceeding,
 
                                       89
<PAGE>
although the court may order that all or a portion of the expenses incurred by
any stockholder in connection with an appraisal, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts utilized in the
appraisal proceeding, be charged against the value of all of the shares of
AirTouch common stock, AirTouch Class D preferred stock or AirTouch Class E
preferred stock entitled to an appraisal.
 
    Any holder of AirTouch common stock, AirTouch Class D preferred stock or
AirTouch Class E preferred stock who duly demands appraisal in compliance with
Section 262 will not, after the merger or the internal reorganization, as the
case may be, be entitled to vote the holder's shares for any purpose or be
entitled to the payment of dividends or other distributions on those shares
other than dividends or other distributions payable to holders of record as of a
record date prior to the merger or the internal reorganization, as the case may
be.
 
    If any stockholder who demands appraisal of shares of AirTouch common stock,
AirTouch Class D preferred stock or AirTouch Class E preferred stock under
Section 262 fails to perfect, or effectively withdraws or loses, the holder's
right to appraisal, the shares of the stockholder will be converted into the
right to receive the merger consideration pursuant to the merger or the internal
reorganization, as the case may be, without interest.
 
    A stockholder will fail to perfect and lose the right to appraisal if he
does not file a petition for appraisal within 120 days after the date the merger
or internal reorganization, as the case may be, becomes effective, or if the
stockholder delivers to AirTouch a written withdrawal of a demand for appraisal
and an acceptance of the terms offered upon the merger or the internal
reorganization, as the case may be. However, any attempt to withdraw a demand
for appraisal made more than 60 days after the date the merger or the internal
reorganization, as the case may be, becomes effective will require the written
approval of AirTouch and, once a petition for appraisal is filed, an appraisal
proceeding may not be dismissed as to any holder absent court approval.
 
    A HOLDER OF AIRTOUCH COMMON STOCK, CLASS D PREFERRED STOCK OR CLASS E
PREFERRED STOCK MAY LOSE APPRAISAL RIGHTS IF THE HOLDER FAILS TO FOLLOW THE
STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR PERFECTING APPRAISAL RIGHTS.

DIVIDEND DATA
 
    VODAFONE
 
    The following table sets forth dividends announced and paid in respect of
Vodafone ordinary shares and Vodafone ADSs, for the periods indicated, including
the associated U.K. tax credit available to beneficial owners of Vodafone
ordinary shares or Vodafone ADSs who are resident in the U.S. for tax purposes,
but before deduction of U.K. withholding taxes. See "MATERIAL TAX
CONSEQUENCES--United Kingdom Tax Consequences of the Ownership of Vodafone
AirTouch Ordinary Shares and Vodafone AirTouch ADSs." Therefore, the amounts
shown are not those that were actually paid to holders of Vodafone ordinary
shares and Vodafone ADSs. The percentage of any dividend represented by the
associated U.K. tax credit has varied over the periods indicated. As of April 6,
1999, the U.K. tax credit is now effectively completely set off by the amount of
applicable U.K. withholding taxes. The U.K. tax credit is currently one-ninth of
the cash dividend. Dividends have been translated from pounds sterling per
Vodafone ADS into U.S. dollars using the exchange rate on the date the dividends
were paid. Dividends have historically been paid semi-annually, with the regular
interim dividend with respect to the first six months of Vodafone's year payable
in February and the regular final dividend with respect to the second six months
of Vodafone's fiscal year payable in August. See "EXCHANGE RATES," "VODAFONE

                            DESCRIPTION OF VODAFONE
 
    Vodafone is a leading international provider of mobile telecommunications
services. It owns interests in mobile operations in the United Kingdom and 12
other countries which, as of March 31, 1999, served over 10.4 million customers
based on Vodafone's ownership share of its telecommunications ventures, of which
over 9.5 million are connected to digital networks. Vodafone was formed in 1984
as a subsidiary of Racal Electronics Plc. Approximately twenty percent of
Vodafone, then known as Racal Telecom Limited, was offered to the public in
October 1988. Vodafone was spun off from Racal Electronics and became an
independent company in September 1991.
 
    Vodafone's principal business consists of the operation in the United
Kingdom of digital and analog cellular radio telephone and paging networks.
Vodafone was the first cellular operator in the United Kingdom to open its
network for service. After commencing service on its analog network on January
1, 1985 it subsequently launched one of the world's first digital networks in
July 1992. It has been the U.K. market leader since 1986 and is presently the
largest of the four United Kingdom operators with more than 5.5 million
customers at March 31, 1999, of which over 1.8 million are on its innovative
"Pay As You Talk" prepaid service.
 
    Outside of the United Kingdom, Vodafone currently has interests, including,
in most cases, board representation and significant operating influence, in
cellular operators in Australia, Egypt, Fiji, France, Germany, Greece, Malta,
the Netherlands, New Zealand, South Africa, Sweden and Uganda. These cellular
interests are licensed to serve over 360 million people. At March 31, 1999,
Vodafone's customer base outside of the U.K. was almost 4.9 million, based on
its ownership shares of its ventures. Vodafone also owns an approximate 3.0%
interest in Globalstar, which is constructing and will operate a 48 low-earth
orbit satellite communications system. Vodafone is licensed to be the exclusive
service provider for Globalstar in Australia, Greece, Lesotho, Malta, South
Africa, Swaziland and the United Kingdom.
 
                            DESCRIPTION OF AIRTOUCH
 
    AirTouch is a leading international mobile telecommunications company, with
a significant presence in the United States, Europe and Asia. As of March 31,
1999, AirTouch had over 18.8 million customers based on its ownership share of
the cellular, paging and personal communications service ventures in which it
has an interest. At that date, those ventures were licensed to serve an
estimated 723 million people.
 
    In the United States, AirTouch's cellular and PCS ventures had over 10.3
million customers at March 31, 1999, of which AirTouch's proportionate share was
approximately 8.7 million customers. AirTouch's interests in its U.S. cellular
and PCS ventures at March 31, 1999 represented over 95 million POPs, a number
reflecting the population of a market multiplied by AirTouch's ownership
interest in a licensee operating in that market. AirTouch controls or shares
control over cellular systems in 15 of the 30 largest cellular markets in the
United States, including Los Angeles, Detroit, San Francisco, Atlanta, San
Diego, Minneapolis, Phoenix, Seattle, Denver, Cleveland, Portland, San Jose,
Kansas City, Cincinnati and Sacramento. In addition, through PrimeCo Personal
Communications, L.P., AirTouch shares control over PCS systems operations in
over 30 major U.S. cities, including Chicago, Dallas, Tampa, Houston, Miami, New
Orleans and Milwaukee.
 
    Outside the U.S., as of March 31, 1999, AirTouch's cellular ventures were
licensed to serve more than 570 million people and had over 26 million
customers, of which AirTouch's proportionate share was approximately 6.6
million. AirTouch holds significant ownership interests, with board
representation and significant operating influence, in cellular systems
operating in Belgium, Egypt, Germany, India, Italy, Japan, Poland, Portugal,
Romania, South Korea, Spain and Sweden.
 
    Industry surveys indicate that AirTouch is also among the largest providers
of paging services in the United States, with approximately 3.5 million units in
service as of March 31, 1999. AirTouch also owns an approximate 5.2% interest in
Globalstar and is licensed to be the exclusive service provider for Globalstar
in the United States and the Caribbean region, Indonesia, Japan, Malaysia and
owns interests in the exclusive service providers in Mexico and Canada.

                              RECENT DEVELOPMENTS
 
VODAFONE
 
    For the six months ended March 31, 1999, Vodafone's operating revenues were
in line with management's expectations. Customer growth continued to be strong
and is expected to remain robust for the mobile telecommunications industry
generally. Increasing competition in some markets may cause Vodafone ventures in
such markets to experience a slightly lower rate of increase in the number of
customers than in 1998. Vodafone expects the revenues of Vodafone AirTouch to
continue to grow, notwithstanding the industry-wide trend towards decreasing
average revenue per customer. Vodafone also expects capital expenditures to rise
in accordance with increasing usage and number of customers. Vodafone currently
expects to publish its results for the year ended March 31, 1999 on June 8,
1999.
 
AIRTOUCH
 
    On April 22, 1999, AirTouch released its unaudited operating results for the
quarter ended March 31, 1999. AirTouch acquired the U.S. cellular and PCS
businesses of MediaOne Group, Inc. on April 6, 1998. Accordingly, AirTouch's
results for the quarter ended March 31, 1998, set forth below, do not include
the results of those acquired businesses for the periods prior to the
acquisition and, therefore, its comparability to the results for the quarter
ended March 31, 1999 is limited. Selected results for these periods include:

                     VODAFONE AIRTOUCH FOLLOWING THE MERGER
 
    Upon completion of the merger, Vodafone will change its name to "Vodafone
AirTouch Public Limited Company." The worldwide headquarters of Vodafone
AirTouch will be in Newbury, England. Following the merger, AirTouch's San
Francisco office will be the U.S./Asia Pacific regional headquarters for
Vodafone AirTouch. In addition, Vodafone has agreed that for three years
following the date the merger becomes effective, Vodafone AirTouch will maintain
a significant business presence in the San Francisco Bay Area and will maintain
AirTouch's Bay Area Research Technology Facility.
 
    Information regarding the management of Vodafone AirTouch after the merger
is contained under the caption "DIRECTORS AND MANAGEMENT OF VODAFONE AIRTOUCH
FOLLOWING THE MERGER" and additional information regarding the expected cost
savings and revenue enhancements to be achieved in connection with the merger is
contained under the caption "THE MERGER--Reasons for the Merger."
 
FINANCIAL INFORMATION
 
    Vodafone AirTouch will, like Vodafone presently, have a financial year-end
of March 31. Vodafone AirTouch will prepare its financial statements in
accordance with U.K. GAAP and present them in pounds sterling. Vodafone AirTouch
financial statements will also include a summary of the effects of the
differences between U.K. GAAP and U.S. GAAP for financial information such as
net income, shareholders' equity and total assets.
 
DIVIDENDS
 
    Vodafone has historically paid dividends on a semi-annual basis and expects
that Vodafone AirTouch will continue to pay semi-annual dividends on Vodafone
AirTouch ordinary shares. The amount of future dividends of Vodafone AirTouch
will be dependent on its earnings and financial condition and other factors
affecting its businesses. Vodafone's aggregate interim and final dividends for
the year ended March 31, 1998, including the associated U.K. tax credit
available to beneficial owners of Vodafone ordinary shares or Vodafone ADSs who
are resident in the U.S. for tax purposes, but before deduction of U.K.
withholding taxes, was 6.91p per ordinary share or $1.12 per ADS (based on the
exchange rate on the date when the dividend was paid). Vodafone's interim
dividend for the six months ended September 30, 1998, including the tax credit
but before U.K. withholding tax, was 3.9p per ordinary share or $0.63 per ADS
based on the exchange rate on the date when the dividend was paid. Because these
amounts include the associated U.K. tax credit, they do not represent the
amounts actually paid to holders of Vodafone ordinary shares or ADSs. Vodafone's
interim dividend for the six months ended September 30, 1998 was paid on
February 12, 1999. Vodafone expects to pay a final dividend in respect of the
year ended March 31, 1999 in August 1999. The record date for this dividend will

    VODAFONE AIRTOUCH UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
INTRODUCTORY NOTE
 
    The following unaudited pro forma consolidated financial information gives
pro forma effect to the merger, after giving effect to the pro forma adjustments
described in the accompanying notes. The unaudited pro forma consolidated
financial information has been prepared from, and should be read in conjunction
with, the respective historical consolidated financial statements and notes
thereto of Vodafone and AirTouch, which are incorporated by reference into this
document. For information on how to obtain any of those documents, see
"SUMMARY--Where You Can Find More Information."
 
    The unaudited pro forma consolidated financial information is provided for
illustrative purposes only and does not purport to represent what the actual
results of operations or the financial position of Vodafone AirTouch would have
been had the merger occurred on the respective dates assumed, nor is it
necessarily indicative of Vodafone AirTouch's future operating results or
consolidated financial position.
 
    The unaudited pro forma consolidated financial information has been prepared
in accordance with U.K. GAAP, which differs in certain respects from U.S. GAAP.
Note 32 to the consolidated financial statements of Vodafone, included in
Vodafone's Form 20-F filed with the SEC on July 21, 1998, which presented U.S.
GAAP financial information for the years ended March 31, 1996, 1997 and 1998,
provides a description of the principal differences between U.K. GAAP and U.S.
GAAP as they relate to Vodafone. Note 8 to the unaudited pro forma consolidated
financial information contains a reconciliation of the pro forma net loss and
loss per share and pro forma shareholders' equity to U.S. GAAP.
 
    Vodafone AirTouch will account for the merger as an acquisition under U.K.
GAAP in accordance with Financial Reporting Standard 6, "Acquisitions and
Mergers." Vodafone AirTouch will account for the merger as a purchase for U.S.
GAAP purposes in accordance with APB Opinion No. 16, "Business Combinations."
 
    The historical financial statements of AirTouch have been prepared in
accordance with U.S. GAAP. For purposes of presenting the unaudited pro forma
consolidated financial information, financial information relating to AirTouch
has been adjusted to conform materially with Vodafone's accounting policies
under U.K. GAAP as described in Note 4 to the unaudited pro forma consolidated
financial information. On April 6, 1998, AirTouch acquired NewVector, which held
the U.S. cellular business of MediaOne Group, Inc., and MediaOne's interest in
PrimeCo pursuant to the Agreement and Plan of Merger dated as of January 29,
1998 among U S WEST, Inc., MediaOne, NewVector, U S WEST PCS Holdings, Inc. and
AirTouch, as described in more detail in the Form 8-K/A filed by AirTouch on
April 23, 1998, incorporated by reference in this document. Pro forma effect has
been given to this acquisition in the pro forma consolidated financial
information.
 
    The pro forma merger adjustments reflected in the accompanying unaudited pro
forma consolidated financial information reflect estimates made by Vodafone
management and assumptions that it believes to be reasonable. The unaudited pro
forma consolidated financial information does not take into account any
synergies, including cost savings, or any severance and restructuring costs,
which may or are expected to occur as a result of the merger. See "THE
MERGER--Reasons for the Merger."
 
    The pro forma amounts pertaining to the consolidated Vodafone AirTouch
entity in the unaudited pro forma consolidated financial information are
presented in pounds sterling and are also expressed in U.S. dollars, the latter
being presented solely for convenience and translated at the noon buying rate on
September 30, 1998, which was $1.6995 to L1.00.

      VODAFONE AIRTOUCH UNAUDITED PRO FORMA CONSOLIDATED INCOME STATEMENT
                      SIX MONTHS ENDED SEPTEMBER 30, 1998
 
    The following pro forma consolidated income statement for the six months
ended September 30, 1998 is derived from the unaudited consolidated profit and
loss account of Vodafone for the period then ended and AirTouch's unaudited
income statements for the quarters ended June 30, 1998 and September 30, 1998,
as adjusted to U.K. GAAP, after giving effect to the pro forma adjustments
described in the notes to the unaudited pro forma consolidated financial
information. These adjustments have been determined as if the merger took place
on April 1, 1997, the first day of the earliest period presented in the Vodafone
AirTouch unaudited pro forma consolidated financial information. This
information has been prepared from, and should be read in conjunction with, the
respective consolidated financial statements and notes thereto of Vodafone and
AirTouch, which are incorporated by reference into this document. The unaudited
pro forma consolidated income statements omit the results of AirTouch for the
three months ended March 31, 1998. The pro forma financial information for the
six month period ended September 30, 1998 has been prepared on this basis to
reflect the basis of consolidation which Vodafone AirTouch expects to adopt
after the merger as AirTouch's financial year end will be changed to March 31.
The pro forma U.K. GAAP group turnover and profit before preference dividends of
AirTouch for the three months ended March 31, 1998, were $1,299 million and $193
million, respectively. The table below has been prepared in accordance with U.K.
GAAP.

NOTES TO THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
1.  TRANSLATION OF AIRTOUCH FINANCIAL STATEMENTS
 
    AirTouch presents its financial statements in U.S. dollars. The results of
AirTouch, as restated under U.K. GAAP, have been translated into pounds sterling
at the average rate of $1.6635 to L1.00 for the six months ended September 30,
1998 and $1.6467 to L1.00 for the year ended December 31, 1997.
 
    The AirTouch balance sheet at September 30, 1998 in U.S. dollars, as
restated under U.K. GAAP, has been translated into pounds sterling at $1.6994 to
L1.00.
 
    These translations should not be taken as assurances that the pounds
sterling amounts currently represent U.S. dollar amounts or could be converted
into U.S. dollars at the rate indicated or at any other rate, at any time.
 
2.  PRO FORMA ACQUISITION ADJUSTMENTS
 
    (a) The unaudited pro forma consolidated financial information records the
merger as being accounted for as an acquisition with the excess of the fair
value of the consideration over the fair value of net assets acquired being
allocated to goodwill.
 
    The unaudited pro forma consolidated financial information assumes that
Vodafone AirTouch will issue 5 Vodafone AirTouch ordinary shares, equivalent to
0.5 of a Vodafone AirTouch ADS, and pay $9.00 in cash in exchange for each share
of AirTouch common stock. The total purchase price assumed is based on the
Vodafone ADS price at January 15, 1999 and assumes exercise of all vested
AirTouch stock options and conversion of all shares of AirTouch Class B and
AirTouch Class C preferred stock outstanding at that date. The shares of
AirTouch Class D and E preferred stock are assumed to remain outstanding. As a
result, 307.5 million new Vodafone AirTouch ADSs are assumed to be issued.
 
    The consideration to be paid in the merger on the basis of the assumptions
noted above includes a cash consideration of $5,535 million (L3,257 million)
which will be financed by the new credit facility entered into on April 16, 1999
by Vodafone and AirTouch as well as from generally available funds of Vodafone
and AirTouch. Estimated professional fees of L94 million (primarily legal,
investment bankers' and accountants' fees) related to the acquisition are
assumed to be accounted for as acquisition costs (L74 million) and share issue
costs (L20 million). The pro forma net cash requirement is shown below.

    The unaudited pro forma consolidated financial information also includes the
capitalization of L27 million of the share premium account as a result of the
redenomination of the Vodafone ordinary shares.
 
    A preliminary allocation of the purchase price has been performed for
purposes of the unaudited pro forma consolidated financial information based on
initial appraisal estimates and other valuation studies which are in process and
assumptions which Vodafone believes are reasonable. The final
 
                                      106
<PAGE>
allocation is subject to completion of these studies, which is expected to be
within the next twelve months. However, Vodafone does not expect the differences
between the preliminary and final allocations to have a material impact on
shareholders' equity or profit for the period. A summary, in accordance with
U.K. GAAP, is shown below.

    Goodwill is amortized as follows:
 
    - L2,371 million over 5 years for goodwill nominally attributable to
      customer lists.
 
    - L15,381 million over 40 years for goodwill nominally attributable to U.S.
      cellular and paging operations, the licenses of which are assumed to have
      a life of at least 40 years without significant cost for renewal.
 
    - L16,727 million over periods ranging from 8 to 40 years, which is the
      remaining life of the licenses, for goodwill nominally attributable to non
      U.S. cellular operations.
 
                                      107
<PAGE>
    The pro forma goodwill amortization is L1,922 million in the year ended
March 31, 1998 and L961 million in the six months ended September 30, 1998. For
the year ended March 31, 1998, this goodwill amortization has been allocated to
operating profit (L758 million), share of profit in associated undertakings
(L1,104 million) and share of profit in joint ventures (L60 million). For the
six months ended September 30, 1998, the amounts are L379 million, L552 million
and L30 million, respectively.
 
    (b) Records the change in accounting required in respect of the Vodafone and
AirTouch investments in Europolitan Holdings AB and Misrfone Telecommunications
Company SAE.
 
    Europolitan is a 51% majority owned subsidiary of AirTouch and a 20% equity
accounted investment of Vodafone. On a pro forma consolidated basis Europolitan
is a 71% majority owned subsidiary.
 
    Misrfone is a 30% equity accounted investment of both Vodafone and AirTouch.
On a pro forma consolidated basis Misrfone is a 60% majority owned subsidiary.
 
    These adjustments had no impact on profit for the period.
 
    (c) Records the removal of existing AirTouch intangible asset amortization.
 
    (d) Records interest expense accrued on L3,095 million of pro forma net cash
required to fund the merger, assuming an interest rate of 6.5%. The effect of an
1/8% increase in interest rates would be to increase interest expense by L2
million for the six months ended September 30, 1998 and by L4 million for the
year ended March 31, 1998.
 
    (e) Records the amortization of bank arrangement fees of L65 million applied
against new borrowings, amortized over a period of between two and five years,
the assumed period of borrowing.
 
    (f) Records the tax effects of the relevant pro forma adjustments arising
from the acquisition at the assumed effective rate of 36%. Relevant pro forma
adjustments to the pro forma consolidated income statement include interest,
amortization of goodwill, amortization of bank arrangement fees and the change
in accounting for Europolitan and Misrfone. Other than for the amortization of
goodwill, these adjustments were tax effected at the assumed effective rate
resulting in a net tax benefit of L77 million for the year ended March 31, 1998
and L39 million for the six months ended September 30, 1998.
 
    (g) Records the adjustments to reclassify the AirTouch Class D and Class E
preferred stock and related dividends as non-equity minority interests and
remove the AirTouch Class B and Class C preferred stock dividends.
 
3.  RECLASSIFICATION
 
    Reclassifications have been made to the AirTouch and NewVector historical
financial information presented under U.S. GAAP to conform to Vodafone's
presentation under U.K. GAAP.
 
    The principal income statement reclassifications relate to:
 
    - presentation of minority interests below profit after taxation;
 
    - presentation of foreign exchange income/expense as part of operating
      profit; and
 
    - presentation of miscellaneous income/expense as part of operating profit
      or disposal of fixed asset investments, as applicable.
 
    The principal balance sheet reclassifications relate to:
 
    - reclassifications of deferred charges/non-current assets to the relevant
      U.K. GAAP headings: investments, debtors and provisions for liabilities
      and charges;
 
    - reclassification of other current assets to debtors and provisions for
      liabilities and charges;
 
    - reclassification of deferred credits to creditors and debtors;
 
                                      108
<PAGE>
    - reclassification of other reserves to profit and loss account reserves,
      revaluation reserve and investments; and
 
    - reclassification of redeemable preferred stock to capital and reserves.
 
    None of these reclassification adjustments has an impact on net income or
shareholders' equity with the exception of the reclassification of restricted
stock and treasury stock to debtors and investments, respectively, which
increases shareholders' equity by $136 million.
 
4.  U.S. TO U.K. GAAP ADJUSTMENTS
 
    Accounting principles generally accepted in the U.K. differ in material
respects from those generally accepted in the U.S. The differences which are
material to restating the historical consolidated financial statements of
AirTouch and NewVector to comply with U.K. GAAP (as set out on pages 103 to 105)
and which are material to reconciling the Vodafone AirTouch unaudited pro forma
consolidated net income and shareholders' equity to U.S. GAAP (as set out in
Note 8 to the unaudited pro forma consolidated financial information) are
described below.
 
    ADJUSTMENTS TO HISTORICAL AIRTOUCH FINANCIAL STATEMENTS:
 
    (a) CAPITALIZED INTEREST
 
    Under U.K. GAAP, the policy of Vodafone is not to include interest on
borrowings used to finance the construction of an asset in the cost of the
asset. Under U.S. GAAP, the interest cost on borrowings used to finance the
construction of an asset is capitalized during the period of construction until
the date that the asset is placed in service. This interest cost is amortized
over the estimated useful life of the related asset.
 
    (b) GOODWILL AND OTHER INTANGIBLES
 
    Under U.K. GAAP, the policy followed by Vodafone prior to the introduction
of Financial Reporting Standard 10, "Goodwill and Intangible Assets" (which is
effective for accounting periods ending on or after December 23, 1998 and has
been adopted by Vodafone on a prospective basis) was to write-off goodwill
against shareholders' equity in the year of acquisition. FRS 10 requires
goodwill to be capitalized and amortized over its estimated useful life.
 
    Under U.S. GAAP, intangibles arising on the acquisition of an equity stake
would be capitalized and amortized over their useful economic lives.
 
    Investments in associated undertakings, under U.S. GAAP, can also include an
element of goodwill in the amount of the excess investment over the acquirer's
share in the fair value of the net assets at the date of the investment. Under
U.K. GAAP, the treatment followed by Vodafone prior to the implementation of FRS
10 was to write-off the excess of the purchase consideration over the fair value
of the stake in the associate acquired against shareholders' equity in the year
of purchase. AirTouch has historically capitalized interest on start up
investments in certain equity investments. Under U.K. GAAP these amounts have
been charged to the profit and loss account in the period incurred.
 
    (c) TREASURY STOCK
 
    Under U.S. GAAP if a company acquires shares of its own capital stock, the
cost of the acquired shares is generally shown as a deduction from capital.
Under U.K. GAAP it is necessary to evaluate the recoverability of the recorded
investment in treasury stock based on the intent of the company with respect to
releasing the shares. Where the company intends to release the shares for option
exercises, the carrying value of treasury stock is evaluated against the
exercise price of outstanding stock options. Amounts in excess of the investment
recorded for treasury stock above the anticipated aggregate exercise price of
stock options to be exercised should be recognized as a loss in the income
statement.

    (d) LICENSE FEE AMORTIZATION
 
    Under U.K. GAAP, Vodafone has adopted a policy of amortizing license fees in
proportion to the expected usage of the network during the start up period and
then on a straight line basis. Under U.S. GAAP, license fees are amortized on a
straight line basis from the date that operations commence to the date the
license expires.
 
    (e) EQUITY ACCOUNTING
 
    U.K. GAAP requires the investor's share of operating profit or loss,
exceptional items and interest income or expense of associated undertakings and
joint ventures to be shown separately from those of the group on the face of the
income statement. The charges for interest and taxation for associated
undertakings and joint ventures may be aggregated within the group interest and
taxation amounts shown on the face of the income statement, but must be
disclosed in the notes to the accounts. For U.S. GAAP, the after-tax profits or
losses (i.e., operating results after exceptional items, interest and taxation)
should be included in the income statement as a single line item.
 
    (f) DEFERRED TAXATION
 
    Under the U.K. GAAP partial provision method, deferred taxation is only
provided where timing differences are expected to reverse in the foreseeable
future. For U.S. GAAP, under the liability method, deferred taxation is provided
for temporary differences between the financial reporting basis and the tax
basis of assets and liabilities at enacted tax rates expected to be in effect
when these amounts are realized or settled.
 
    (g) INVESTMENTS
 
    Under U.K. GAAP, quoted investments held as fixed asset investments are
carried at the lower of cost or recoverable amount. Under U.S. GAAP,
available-for-sale investments are carried at market value with the unrealized
gain or loss from historical cost excluded from earnings and reported in other
comprehensive income and included as a separate line item in share capital and
reserves.
 
    (h) TAX BENEFIT ON OPTION EXERCISES
 
    Under U.K. GAAP, the tax benefit received by AirTouch on the exercise of
share options by employees, being the tax on the difference between the market
value on the date of exercise and the exercise price, is shown as a component of
the tax charge for the period. Under U.S. GAAP, this tax benefit is shown as a
reduction of paid in capital on issue of shares.
 
    ADJUSTMENTS TO HISTORICAL NEWVECTOR FINANCIAL STATEMENTS:
 
    (i) SUMMARY
 
    The differences which are material to restating the historical consolidated
financial statements of NewVector incorporated herein relate to goodwill and
other intangibles and deferred taxation as described in (b) and (f) above.
 
    ADJUSTMENTS TO VODAFONE AIRTOUCH UNAUDITED PRO FORMA CONSOLIDATED NET INCOME
      AND SHAREHOLDERS' EQUITY:
 
    (j) SUMMARY
 
    The differences which are material to restating the Vodafone AirTouch
unaudited pro forma consolidated net income and shareholders' equity to U.S.
GAAP as set out in Note 8 to the unaudited pro forma consolidated financial
information relate to capitalized interest, goodwill and other intangibles,
treasury stock, license fee amortization and deferred taxation as described in
(a), (b), (c), (d) and (f) together with the adjustment for proposed dividends
and determination of the purchase price described in (k) and (l) below.
 
                                      110
<PAGE>
    (k) PROPOSED DIVIDENDS
 
    Under U.K. GAAP, final dividends are included in the financial statements
when recommended by the board of directors to the shareholders. Under U.S. GAAP,
all dividends are included in the financial statements when declared by the
board of directors.
 
    (l) DETERMINATION OF THE PURCHASE PRICE
 
    Under U.K. GAAP and U.S. GAAP the purchase price of a transaction accounted
for as an acquisition is based on the fair value of the consideration. In the
case of share consideration, under U.K. GAAP the fair value of such
consideration is based on the share price at completion of the acquisition.
Under U.S. GAAP the fair value of the share consideration is based on the
average share price over a reasonable period of time before and after the
proposed acquisition is announced.
 
5.  NEWVECTOR ACQUISITION ADJUSTMENTS
 
    The pro forma adjustments relating to the merger of AirTouch and NewVector
have been prepared from, and should be read in conjunction with, AirTouch's
current report on Form 8-K/A which was filed on April 23, 1998. The pro forma
adjustments have been restated, where necessary, to comply with U.K. GAAP.
 
6.  COST SAVINGS
 
    Vodafone and AirTouch estimate that the merger will result in after tax net
cash flow savings of approximately L200 million ($340 million) per year by the
year ending March 31, 2002. The unaudited pro forma consolidated financial
information does not contain an adjustment for the anticipated benefits of these
cash flow cost savings. There can be no assurance that anticipated cost savings
will be achieved in the expected amounts or at the times anticipated.
 
7.  EMPLOYMENT AGREEMENTS
 
    AirTouch has entered into employment agreements with a number of directors
and officers of AirTouch. These provide for severance payments, accelerated
vesting of incentive awards, full vesting of supplemental pension benefits and
continued coverage of welfare benefit arrangements after termination date if the
named executive's or officer's employment terminates under certain circumstances
within three years after a change in control of AirTouch. See "THE MERGER--
Interests of Members of AirTouch Board and Management in the Merger." To the
extent that any such amounts become payable, they have not been included in the
unaudited pro forma consolidated financial information.

                DESCRIPTION OF VODAFONE AIRTOUCH ORDINARY SHARES
 
GENERAL
 
    The following information is a summary of the material terms of the ordinary
shares as set out in the Vodafone memorandum and articles of association as
presently in effect and taking account of amendments to the Vodafone memorandum
and articles of association proposed to be adopted at the extraordinary general
meeting of Vodafone shareholders, which would take effect upon the merger
becoming effective. You are encouraged to read the form of memorandum and
articles of association proposed for Vodafone AirTouch after the merger which is
filed as an exhibit to the Registration Statement of which this proxy
statement/prospectus forms a part. See also "DESCRIPTION OF VODAFONE AIRTOUCH
AMERICAN DEPOSITARY SHARES" and "COMPARISON OF RIGHTS OF AIRTOUCH STOCKHOLDERS
AND VODAFONE AIRTOUCH SHAREHOLDERS."
 
    Vodafone AirTouch ordinary shares issued in exchange for AirTouch common
stock in the merger will be delivered in the form of Vodafone AirTouch ADSs
which will each represent ten Vodafone AirTouch ordinary shares. The amended and
restated deposit agreement among The Bank of New York, Vodafone AirTouch,
AirTouch and you as an ADS holder will govern the rights of holders of Vodafone
AirTouch ADSs as described in "DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN
DEPOSITARY SHARES." You should be aware that these rights are different from the
rights of the holders of Vodafone AirTouch ordinary shares.
 
    All of the issued Vodafone ordinary shares are fully paid. Vodafone ordinary
shares are represented in certificated form and also in uncertificated form
under "CREST". CREST is an electronic settlement system in the United Kingdom
which enables Vodafone ordinary shares to be evidenced other than by a physical
certificate and transferred electronically rather than by delivery of a physical
certificate. After the merger, all Vodafone AirTouch ordinary shares, including
those underlying the Vodafone AirTouch ADSs to be issued in the merger:
 
    - may be represented by certificates in registered form issued (subject to
      the terms of issue of the shares) following issuance or receipt of the
      form of transfer bearing the appropriate stamp duty by Vodafone AirTouch
      registrars, Computershare Services PLC, P.O. Box 82, Caxton House,
      Redcliffe Way, Bristol, BS99 7NH, England;
 
    - may be in uncertificated form with the relevant CREST member account being
      credited with the Vodafone AirTouch ordinary shares issued or transferred;
      or
 
    - may be in the form of bearer shares if the amendments described below are
      adopted at the extraordinary general meeting of Vodafone shareholders.
 
    Vodafone AirTouch ADS holders shall have the same rights with respect to the
Vodafone AirTouch ordinary shares represented by their Vodafone AirTouch ADSs,
irrespective of whether those ordinary shares are in registered or bearer form
and, if they are in registered form, irrespective of whether they are
certificated or uncertificated. Under English law, persons who are neither
residents nor nationals of the U.K. may freely hold, vote and transfer Vodafone
AirTouch ordinary shares in the same manner and under the same terms as U.K.
residents or nationals.
 
REDENOMINATION
 
    Immediately prior to the merger becoming effective, Vodafone proposes to
redenominate the nominal value of the ordinary share capital of Vodafone from a
nominal value of 5p to a nominal value of $0.10. This proposal will require the
approval of Vodafone shareholders at the Vodafone extraordinary general meeting
and confirmation by the High Court of England. A quorum of two
 
                                      114
<PAGE>
persons entitled to vote upon the business to be transacted and the approval of
at least 75% of the votes cast by Vodafone shareholders present in person, or if
on a poll, in person or by proxy, is required at the Vodafone extraordinary
general meeting for the redenomination of Vodafone ordinary share capital and
the amendments to the Vodafone memorandum and articles of association required
to effect it.
 
    The merger is not conditioned upon the redenomination being approved or
becoming effective. If the Vodafone ordinary shares are not redenominated into
U.S. dollars there will be no direct effect on holders of AirTouch common stock.
However, a stamp duty reserve tax liability of 1.5% of the issue price of the
Vodafone AirTouch ordinary shares issued to AirTouch stockholders (estimated at
approximately $792 million, based on a price per share of 1,066p (the closing
middle market quotation for Vodafone ordinary shares as quoted in the daily
Official List of the London Stock Exchange on April 20, 1999, the last
practicable date prior to the printing of this document)) would arise and be
jointly payable by Vodafone AirTouch and AirTouch on the issue of Vodafone
AirTouch ADSs. There are no material differences between ordinary shares
denominated in pounds sterling and ordinary shares denominated in U.S. dollars.
 
    At April 20, 1999, 3,099,507,981 Vodafone ordinary shares were issued and
outstanding. At the Vodafone extraordinary general meeting to be held on May 24,
1999, shareholders of Vodafone will, in addition to voting with respect to
approval of the merger, vote on proposals
 
    - to increase the authorized share capital of Vodafone from L200,000,000 to
      $816,000,000 and L50,000 (Resolution 18); or
 
    - if the redenomination (Resolution 18) is not effected, to increase the
      authorized share capital from L200,000,000 to L408,000,000 (Resolution 3);
      and
 
    - in either case, to authorize the directors of Vodafone AirTouch upon the
      merger becoming unconditional to allot Vodafone AirTouch ordinary shares
      in exchange for AirTouch common stock, and after the merger to allot
      additional Vodafone AirTouch ordinary shares, and to issue some of these
      shares for cash, disapplying shareholder rights of preemption in certain
      circumstances. See "Preemptive Rights and New Issues of Shares" below.
 
The approval of these proposals, excluding the redenomination and the
disapplication of shareholder preemption rights, is required as a condition to
the merger. See "THE VODAFONE EXTRAORDINARY GENERAL MEETING."
 
DIVIDENDS
 
    Holders of Vodafone AirTouch ordinary shares may, by ordinary resolution,
declare dividends but may not declare dividends in excess of the amount
recommended by the directors. The directors may also pay interim dividends. No
dividend may be paid other than out of profits available for distribution.
Dividends on Vodafone AirTouch ordinary shares will be announced and paid in
pounds sterling. Dividends with respect to Vodafone AirTouch ADSs held by the
depositary will be paid in U.S. dollars, and the depositary will distribute them
to the holders of Vodafone AirTouch ADSs.
 
    The Vodafone AirTouch memorandum and articles of association will permit a
scrip dividend scheme or schemes under which holders of Vodafone AirTouch
ordinary shares may be given the opportunity to elect to receive fully paid
Vodafone AirTouch ordinary shares instead of cash, or a combination of shares
and cash, with respect to future dividends. The scrip dividend scheme will not
be available to Vodafone AirTouch shareholders resident in the U.S. or Canada.
Holders of Vodafone AirTouch ADSs will be eligible to participate in Vodafone
AirTouch's "Global BuyDIRECT" plan
 
                                      115
<PAGE>
administered by The Bank of New York which, among other things, provides for
automatic dividend reinvestments to purchase Vodafone AirTouch ADSs.
 
VOTING RIGHTS
 
    Vodafone has proposed amendments to its memorandum and articles of
association for approval at the Vodafone extraordinary general meeting to
provide that voting on special and extraordinary resolutions at a general
meeting shall be decided on a poll. On a poll, each shareholder who is entitled
to vote and be present in person or by proxy has one vote for every share held.
See "COMPARISON OF RIGHTS OF AIRTOUCH STOCKHOLDERS AND VODAFONE AIRTOUCH
SHAREHOLDERS--Special Meetings of Shareholders." Ordinary resolutions will
continue to be decided on a show of hands, where each shareholder who is present
at the meeting will have one vote regardless of the number of shares held,
unless a poll is demanded. Subject to shareholder approval, it is also intended
that Vodafone's memorandum and articles of association be amended to allow
persons appointed as proxies of shareholders entitled to vote at general
meetings to vote on a show of hands, in addition to proxies' existing rights to
vote on a poll and attend and speak at general meetings. Holders of Vodafone
AirTouch ordinary shares will not have cumulative voting rights. An
extraordinary resolution at a separate meeting of Vodafone AirTouch ordinary
shareholders, requiring an affirmative vote of at least 75% of the votes cast in
person or, if on a poll, in person or by proxy, is necessary under the Vodafone
AirTouch memorandum and articles of association with respect to any proposal to
vary the rights of ordinary shareholders.
 
    Vodafone AirTouch "B" 7% cumulative fixed rate shares will confer no right
to receive notice of, attend or vote at general meetings, except where the
rights attached to the shares are to be varied or abrogated.
 
    Subject to amendments to the Vodafone memorandum and articles of association
proposed for approval at the Vodafone shareholders' meeting becoming effective,
record holders of Vodafone AirTouch ADSs will be entitled to attend, speak and
vote on a poll or a show of hands at any general meeting of Vodafone AirTouch
shareholders by the depositary's appointment of them as proxies with respect to
the underlying Vodafone AirTouch ordinary shares represented by their Vodafone
AirTouch ADSs. Alternatively, holders of Vodafone AirTouch ADSs will be entitled
to vote by supplying their voting instructions to the depositary or its nominee,
who will vote the Vodafone AirTouch ordinary shares underlying their Vodafone
AirTouch ADSs in accordance with their instructions. In addition, holders of
record of ordinary shares may appoint a proxy including a beneficial owner of
those shares to attend, speak and vote on their behalf. See "COMPARISON OF
RIGHTS OF AIRTOUCH STOCKHOLDERS AND VODAFONE AIRTOUCH SHAREHOLDERS--Voting
Rights."
 
LIQUIDATION RIGHTS
 
    In the event of the liquidation of Vodafone AirTouch, after payment of all
liabilities and the deduction of any provision made under Section 719 of the
U.K. Companies Act 1985 or Section 187 of the U.K. Insolvency Act 1986, which
enables the liquidator to make payments to employees or former employees on the
cessation or transfer of Vodafone's business, the holders of the Vodafone "B" 7%
cumulative fixed rate shares would be entitled to a sum equal to the capital
paid up on such shares in priority to holders of Vodafone AirTouch ordinary
shares.
 
PREEMPTIVE RIGHTS AND NEW ISSUES OF SHARES
 
    Under Section 80 of the U.K. Companies Act, directors are, with certain
exceptions, unable to allot relevant securities without the authority of the
shareholders in a general meeting. Relevant
 
                                      116
<PAGE>
securities as defined in the U.K. Companies Act would include Vodafone AirTouch
ordinary shares or securities convertible into Vodafone AirTouch ordinary
shares. In addition, Section 89 of the U.K. Companies Act imposes further
restrictions on the issue of equity securities (as defined in the U.K. Companies
Act, which would include Vodafone AirTouch ordinary shares and securities
convertible into ordinary shares) which are, or are to be, paid up wholly in
cash and not first offered to existing shareholders. Vodafone's memorandum and
articles of association allow shareholders to authorize directors for a period
up to 15 months, or, if the memorandum and articles of association are amended
at the extraordinary general meeting, for a period up to 5 years, to allot (1)
relevant securities generally up to an amount fixed by the shareholders and (2)
equity securities for cash other than in connection with a rights issue. In
accordance with institutional investor guidelines, the amount of relevant
securities to be fixed by shareholders is normally restricted to one third of
the existing issued ordinary share capital, and the amount of equity securities
to be issued for cash other than in connection with a rights issue is restricted
to 5% of the existing issued ordinary share capital. At Vodafone's annual
general meeting in 1998, these amounts were fixed at L30,000,000 and L7,713,968,
respectively, and at the Vodafone extraordinary general meeting, Vodafone will
ask its shareholders to change these amounts to $198,549,202 and $30,223,868,
respectively, or, if the redenomination does not take place, to L99,274,601 and
L15,111,934.
 
    The authority referred to above granted to the directors at the annual
general meeting in 1998 expires at the earlier of Vodafone's next annual general
meeting or October 21, 1999.
 
DISCLOSURE OF INTERESTS IN SHARES
 
    The U.K. Companies Act will give Vodafone AirTouch the power to require
persons who it believes to have, or to have acquired within the previous three
years, an interest in its voting shares, to disclose certain information with
respect to those interests. Failure to supply the information required may lead
to disenfranchisement of the relevant shares and a prohibition on their transfer
and receipt of dividends and payments in respect of those shares. In this
context, the term "interest" is widely defined and will generally include an
interest of any kind whatsoever in voting shares, including any interest of a
holder of a Vodafone AirTouch ADS. See "COMPARISON OF RIGHTS OF AIRTOUCH
STOCKHOLDERS AND VODAFONE AIRTOUCH SHAREHOLDERS--Disclosure of Interests."
 
CHANGES IN CAPITAL
 
    The Vodafone AirTouch shareholders may pass an ordinary resolution to do any
of the following:
 
    (1) consolidate, or consolidate and then divide, all or any of Vodafone
       AirTouch's share capital into new shares of larger nominal amounts than
       its existing shares;
 
    (2) cancel any shares which have not, at the date of the relevant
       resolution, been subscribed or agreed to be subscribed by any person and
       reduce the amount of Vodafone AirTouch's authorized share capital by the
       amount of the shares so canceled;
 
    (3) divide some or all of Vodafone AirTouch's shares into shares of a
       smaller nominal amount; and
 
    (4) increase Vodafone AirTouch's share capital.
 
    Vodafone AirTouch will also be able to:
 
    (1) with the authority of shareholders by ordinary or special resolution,
       depending on the circumstances relating to the purchase, purchase its own
       shares; and
 
                                      117
<PAGE>
    (2) by special resolution and, where required by the U.K. Companies Act,
       with the sanction of the court, reduce its share capital, any capital
       redemption reserve, share premium account or any other undistributable
       reserve.
 
TRANSFER OF SHARES
 
    Except as described in this paragraph, the Vodafone AirTouch memorandum and
articles of association will not restrict the transferability of Vodafone
AirTouch ordinary shares. Vodafone AirTouch ordinary shares will be able to be
transferred by an instrument in any usual form or in any form acceptable to the
directors. The directors may refuse to register a transfer:
 
       (1) if it is of shares which are not fully paid;
 
       (2) if it is not stamped and duly presented for registration, together
       with the share certificate and evidence of title as the directors
       reasonably require;
 
       (3) if it is with respect to more than one class of shares;
 
       (4) if it is in favor of more than four persons jointly; or
 
       (5) in certain circumstances, if the holder has failed to provide the
       required particulars to the investigating power referred to under
       "--Disclosure of Interests in Shares" above.
 
    Vodafone AirTouch may not refuse to register transfers of Vodafone AirTouch
ordinary shares if this refusal would prevent dealings in the shares on the
London Stock Exchange from taking place on an open and proper basis. The
registration of transfers may be suspended at any time and for any period as the
directors may determine. The register of shareholders may not be closed for more
than 30 days in any year.
 
GENERAL MEETINGS AND NOTICES
 
    A shareholder who is not registered on Vodafone AirTouch's register of
shareholders with an address in the U.K. and who has not supplied to Vodafone
AirTouch an address within the U.K. for the purpose of giving notice will not be
entitled to receive notices from Vodafone AirTouch. In certain circumstances,
Vodafone AirTouch will be able to give notices to shareholders by advertisement
in newspapers in the U.K. Holders of Vodafone AirTouch ADSs will be entitled to
receive notices under the terms of the deposit agreement relating to Vodafone
AirTouch ADSs. See "DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY
SHARES--Voting Rights." Under the Vodafone AirTouch memorandum and articles of
association, the annual general meeting of shareholders will be held within 15
months after the preceding annual general meeting and at a time and place
determined by the directors.
 
LIABILITY OF DIRECTORS AND OFFICERS
 
    See "COMPARISON OF RIGHTS OF AIRTOUCH STOCKHOLDERS AND VODAFONE AIRTOUCH
SHAREHOLDERS--Liability of Directors and Officers" for a discussion of the
inability of an English company to exempt directors and officers from certain
liabilities.
 
REGISTRAR
 
    The registrar for Vodafone AirTouch ordinary shares after the merger will be
Computershare Services PLC, P.O. Box 82, Caxton House, Redcliffe Way, Bristol,
BS99 7NH.

          DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY SHARES
 
GENERAL
 
    The Bank of New York as depositary will issue Vodafone AirTouch ADSs to
holders of AirTouch common stock and AirTouch Class B preferred stock in
certificated or book-entry form upon completion of the merger. Each ADS will
represent ownership interests in ten Vodafone AirTouch ordinary shares and the
right to receive ten Vodafone AirTouch ordinary shares which Vodafone AirTouch
will deposit with the custodian, which currently is the London office of The
Bank of New York. Each ADS will also represent securities, cash or other
property deposited with The Bank of New York but not distributed to ADS holders.
The Bank of New York's Corporate Trust Office is located at 101 Barclay Street,
New York, New York, 10286, its principal executive office is located at One Wall
Street, New York, New York 10286, and the custodian's office is located at 46
Berkeley Street, London W1X 6AA, England.
 
    Because The Bank of New York will actually be the legal owner of the
underlying ordinary shares, you will generally exercise the rights of a
shareholder through it, although you will have the option to attend, speak and
vote at shareholder meetings as its proxy, as described below. An amended and
restated deposit agreement among Vodafone AirTouch, AirTouch, The Bank of New
York and you, as an ADS holder, will set out the obligations of The Bank of New
York. New York law will govern the deposit agreement and the Vodafone AirTouch
American depositary receipts evidencing the ADSs.
 
    You may hold ADSs either directly or indirectly through your broker or
financial institution. If you hold ADSs directly, you are an ADS holder. This
description assumes you hold your ADSs directly. If you hold the ADSs
indirectly, you must rely on the procedures of your broker or financial
institution to assert the rights of ADS holders described in this section. You
should consult with your broker or financial institution to find out what those
procedures are.
 
    The following is a summary of the deposit agreement. Because it is a
summary, it does not contain all the information that may be important to you.
For more complete information, you should read the entire agreement and the
Vodafone AirTouch ADR. Copies of the agreement and the Vodafone AirTouch ADR
will be available for inspection at the Corporate Trust Office of the depositary
and at the London office of the custodian set forth above.
 
SHARE DIVIDENDS AND OTHER DISTRIBUTIONS
 
    HOW WILL YOU RECEIVE DIVIDENDS AND OTHER DISTRIBUTIONS ON THE SHARES?
 
    The Bank of New York will pay to you the cash dividends or other
distributions it or the custodian receives on shares or other deposited
securities, after deducting its fees and expenses. You will receive these
distributions in proportion to the number of ordinary shares your ADSs
represent.
 
    - CASH. The Bank of New York will, as promptly as practicable after payment,
      convert any cash dividend or distribution Vodafone AirTouch pays on the
      shares, other than any dividend or distribution paid in U.S. dollars, into
      U.S. dollars. If that is not possible on a reasonable basis, or if any
      approval from any government is needed and cannot be obtained, the
      agreement allows The Bank of New York to distribute the pounds sterling
      only to those ADS holders to whom it is possible to do so or to hold the
      pounds sterling it cannot convert for the account of the ADS holders who
      have not been paid. It will not invest the pounds sterling and it will not
      be liable for any interest.
 
    Before making a distribution, The Bank of New York will deduct any
    withholding taxes that must be paid under applicable laws. See "MATERIAL TAX
    CONSEQUENCES." It will distribute only whole U.S. dollars and cents and will
    round any fractional amounts to the nearest whole cent.
 
                                      119
<PAGE>
    - SHARES. The Bank of New York will distribute new ADSs representing any
      shares Vodafone AirTouch distributes as a dividend or free distribution,
      if Vodafone AirTouch requests it to make this distribution. The Bank of
      New York will only distribute whole ADSs. It may sell shares which would
      require it to issue a fractional ADS and distribute the net proceeds to
      the holders entitled to those shares. If The Bank of New York does not
      distribute additional cash or ADSs, each ADS will also represent the new
      shares.
 
    - RIGHTS TO RECEIVE ADDITIONAL SHARES. If Vodafone AirTouch offers holders
      of securities any rights, including rights to subscribe for additional
      shares, The Bank of New York may take actions necessary to make these
      rights available to you. If The Bank of New York determines that it is not
      legal or not feasible to make these rights available to you, The Bank of
      New York may sell the rights and allocate the net proceeds to holders'
      accounts. The Bank of New York may allow rights that are not distributed
      or sold to lapse.
 
    If The Bank of New York makes rights available to you, upon instruction from
    you it will exercise the rights and purchase the shares on your behalf. The
    Bank of New York will then deposit the shares and issue ADSs to you. It will
    only exercise rights if you pay it the exercise price and any charges the
    rights require you to pay.
 
    U.S. securities laws may restrict the sale, deposit, cancellation, and
    transfer of the ADSs issued after exercise of rights. In this case, The Bank
    of New York may issue the ADSs under a separate restricted deposit agreement
    which will contain the same provisions as the agreement, except for changes
    needed to put the restrictions in place. The Bank of New York will not offer
    you rights unless those rights and the securities to which the rights relate
    are either exempt from registration or have been registered under the
    Securities Act with respect to a distribution to you. Vodafone AirTouch will
    have no obligation to register under the Securities Act those rights or the
    securities to which they relate.
 
    - OTHER DISTRIBUTIONS. The Bank of New York will send to you anything else
      Vodafone AirTouch distributes on deposited securities by any means The
      Bank of New York thinks is legal, fair and practical. If it cannot make
      the distribution in that way, The Bank of New York may decide to sell what
      Vodafone AirTouch distributed--for example by public or private sale--and
      distribute the net proceeds, in the same way as it does with cash.
 
    Vodafone AirTouch will have no obligation to take any other action to permit
the distribution of ADSs, shares, rights or anything else to ADS holders.
 
DEPOSIT, WITHDRAWAL AND CANCELLATION
 
    HOW DOES THE DEPOSITARY ISSUE ADSS?
 
    The Bank of New York will issue the ADSs that you are entitled to receive in
the merger in certificated or book-entry form, against deposit of the underlying
ordinary shares. The Bank of New York will issue additional ADSs if you or your
broker deposit ordinary shares, along with any appropriate instruments of
transfer, or endorsement, with the custodian. The Bank of New York may also
require you to deliver evidence of any necessary approvals of the governmental
agency in England, if any, which is responsible for regulating currency exchange
at that time, and an agreement transferring your right as a shareholder to
receive dividends or other property. Upon payment of its fees and of any taxes
or charges, such as stamp taxes or stock transfer taxes or fees, The Bank of New
York will register the appropriate number of ADSs in the names you request and
will issue book-entry ADSs or, if you specifically request, deliver the ADSs at
its Corporate Trust Office to the persons you request. THESE TAXES OR CHARGES
WILL NOT BE PAYABLE BY AIRTOUCH STOCKHOLDERS OR BY HOLDERS OF OUTSTANDING
AIRTOUCH STOCK OPTIONS IN CONNECTION WITH THEIR RECEIPT OF VODAFONE AIRTOUCH
ADSS PURSUANT TO THE MERGER AGREEMENT.
 
                                      120
<PAGE>
    HOW DO ADS HOLDERS CANCEL AN ADS AND OBTAIN SHARES?
 
    You may submit a written request to withdraw ordinary shares and turn in
your certificated ADSs, if any, at the Corporate Trust Office of The Bank of New
York. Even though Vodafone may deposit bearer shares in connection with the
merger, any deposited securities that you withdraw will be delivered to you in
registered form. Upon payment of its fees and of any taxes or charges, such as
stamp taxes or stock transfer taxes or fees, The Bank of New York will deliver
the deposited securities underlying the ADSs at the office of the custodian,
except that The Bank of New York may deliver at its Corporate Trust Office any
dividends or distributions with respect to the deposited securities represented
by the ADSs, or any proceeds from the sale of any dividends, distributions or
rights, which may be held by The Bank of New York. Alternatively, at your
request, risk and expense, The Bank of New York will deliver the deposited
securities at its Corporate Trust Office in New York City.
 
VOTING RIGHTS
 
    HOW DO YOU VOTE?
 
    If you are an ADS holder on a record date fixed by The Bank of New York, you
may attend, speak and vote at Vodafone AirTouch shareholder meetings of holders
of the same class of securities as the ordinary shares represented by your ADSs.
 
    The Bank of New York will enable you to attend, speak and vote at a meeting
by appointing you its proxy for the ordinary shares underlying your ADSs. If you
do not wish to attend a meeting, you may appoint The Bank of New York or another
person as your substitute proxy to attend, speak and vote on your behalf.
 
    If you hold Vodafone AirTouch ADSs through a brokerage account or otherwise
in "street name", you will not be entitled to attend or speak at a meeting, but
you will be able to vote your ADSs through the depositary.
 
    The Bank of New York will notify you of the upcoming meeting and arrange to
deliver certain materials to you. The materials will (1) describe the meeting
time, place and the matters to be voted on and (2) explain how you may instruct
The Bank of New York to vote the shares or deposited securities underlying your
ADSs as you direct if you choose to appoint The Bank of New York as your
substitute proxy, or how you may appoint a different substitute proxy. For
instructions to be valid, The Bank of New York must receive them on or before
the date specified in the instructions. The Bank of New York will, to the extent
practical, subject to applicable law and the provisions of the memorandum and
articles of association of Vodafone AirTouch, vote the underlying ordinary
shares as you instruct. The Bank of New York will only vote as you instruct.
 
    Although the depositary will try to send the notice of the vote reasonably
in advance of the meeting, Vodafone AirTouch will not be able to assure that you
will receive the voting materials in time to ensure that you can attend, speak
and vote at a meeting, instruct The Bank of New York to vote your shares or
appoint a different substitute proxy. In addition, The Bank of New York and its
agents are not responsible for failing to carry out voting instructions or for
the manner of carrying out voting instructions.

    The Bank of New York may deduct the amount of any taxes owed from any
payments to you. It may also restrict the transfer of your ADSs or restrict the
withdrawal of your underlying deposited securities until you pay any taxes owed
on your ADSs or underlying securities. It may also sell deposited securities to
pay any taxes owed. You will remain liable if the proceeds of the sale are not
enough to pay the taxes. If The Bank of New York sells deposited securities, it
will, if appropriate, reduce the number of ADSs held by you to reflect the sale
and pay to you any proceeds, or send to you any property, remaining after it has
paid the taxes.
 
RECLASSIFICATIONS, RECAPITALIZATIONS AND MERGERS
 
If Vodafone AirTouch:
 
- -  Changes the nominal or par value of any of the Vodafone AirTouch ordinary
shares
 
- -  Reclassifies, splits or consolidates any of the Vodafone AirTouch ordinary

- -  Distributes securities on any of the Vodafone AirTouch ordinary shares that

    securities; and
 
(2) The Bank of New York will, if Vodafone AirTouch asks it to, issue new ADSs
    or ask you to surrender your outstanding ADSs in exchange for new ADSs
    identifying the new deposited securities.
 
DISCLOSURE OF INTERESTS
 
    The obligation of a holder of Vodafone AirTouch ordinary shares and other
persons with an interest in the shares to disclose information to Vodafone
AirTouch under English law also applies to you and any other persons with an
interest in the ADSs. The consequences for failure to comply with these
provisions will be the same for you and any other persons with an interest as
for a holder of Vodafone AirTouch ordinary shares. See "DESCRIPTION OF VODAFONE
AIRTOUCH ORDINARY SHARES--Disclosure of Interests in Shares."
 
AMENDMENT AND TERMINATION
 
    HOW MAY THE AGREEMENT BE AMENDED?
 
    Vodafone AirTouch may agree with The Bank of New York to amend the deposit
agreement and the Vodafone AirTouch ADRs without your consent for any reason. If
the amendment adds or increases fees or charges, except for taxes and
governmental charges, or prejudices an important right of ADS holders, it will
only become effective three months after The Bank of New York notifies you of
the amendment. AT THE TIME AN AMENDMENT BECOMES EFFECTIVE, YOU ARE CONSIDERED,
BY CONTINUING TO HOLD YOUR ADS, TO AGREE TO THE AMENDMENT AND TO BE BOUND BY THE
AGREEMENT AS AMENDED. HOWEVER, NO AMENDMENT WILL IMPAIR YOUR RIGHT TO RECEIVE
THE DEPOSITED SECURITIES IN EXCHANGE FOR YOUR ADSS.
 
    HOW MAY THE AGREEMENT BE TERMINATED?
 
    The Bank of New York will terminate the deposit agreement if Vodafone
AirTouch asks it to do so, in which case it must notify you at least 30 days
before termination. The Bank of New York may also terminate the agreement after
notifying you if The Bank of New York informs Vodafone AirTouch that it would
like to resign and Vodafone AirTouch does not appoint a new depositary bank
within 90 days.
 
    If any ADSs remain outstanding after termination, The Bank of New York will
stop registering the transfer of ADSs, will stop distributing dividends to ADS
holders, and will not give any further notices or do anything else under the
deposit agreement other than:
 
    (1) collect dividends and distributions on the deposited securities,
 
    (2) sell rights and other property offered to holders of deposited
securities, and
 
    (3) deliver ordinary shares and other deposited securities upon cancellation
of ADSs.
 
    At any time after six months after termination of the deposit agreement, The
Bank of New York may sell any remaining deposited securities. After that, The
Bank of New York will hold the money it received on the sale, as well as any
cash it is holding under the agreement, for the PRO RATA benefit of the ADS
holders that have not surrendered their ADSs. It will not invest the money and
has no liability for interest. The Bank of New York's only obligations will be
to account for the money and cash. After termination, Vodafone AirTouch's only
obligations will be with respect to indemnification of, and to pay specified
amounts to, The Bank of New York.

YOUR RIGHT TO RECEIVE THE SHARES UNDERLYING YOUR ADSS
 
    You have the right to cancel your ADSs and withdraw the underlying shares at
any time except:
 
    - due to temporary delays caused by The Bank of New York or Vodafone
      AirTouch closing its transfer books, the deposit of ordinary shares in
      connection with voting at a shareholders' meeting, or the payment of
      dividends;
 
    - when you owe money to pay fees, taxes and similar charges; or
 
    - when it is necessary to prohibit withdrawals in order to comply with any
      laws or governmental regulations that apply to ADSs or to the withdrawal
      of ordinary shares or other deposited securities.
 
    This right of withdrawal may not be limited by any provision of the
agreement.
 
LIMITATIONS ON OBLIGATIONS AND LIABILITY TO ADS HOLDERS
 
    The deposit agreement expressly limits the obligations of Vodafone AirTouch
and The Bank of New York. It also limits the liability of Vodafone AirTouch and
The Bank of New York. Vodafone AirTouch and The Bank of New York:
 
    - are only obligated to take the actions specifically set forth in the
      deposit agreement without negligence or bad faith;
 
    - are not liable if either of them is prevented or delayed by law, any
      provision of the Vodafone AirTouch articles of association or
      circumstances beyond their control from performing their obligations under
      the agreement;
 
    - are not liable if either of them exercises, or fails to exercise,
      discretion permitted under the agreement;
 
    - have no obligation to become involved in a lawsuit or proceeding related
      to the ADSs or the deposit agreement on your behalf or on behalf of any
      other party unless they are indemnified to their satisfaction; and
 
    - may rely upon any advice of or information from any legal counsel,
      accountants, any person depositing ordinary shares, any ADS holder or any
      other person whom they believe in good faith is competent to give them
      that advice or information.
 
    In the deposit agreement, Vodafone AirTouch and The Bank of New York agree
to indemnify each other under specified circumstances.
 
REQUIREMENTS FOR DEPOSITARY ACTIONS
 
    Before The Bank of New York will issue or register the transfer of an ADS,
make a distribution on an ADS, or permit withdrawal of ordinary shares, Vodafone
AirTouch or The Bank of New York may require:
 
    - payment of taxes, including stamp duty reserve and stock transfer taxes or
      other governmental charges, and transfer or registration fees charged by
      third parties for the transfer of any shares or other deposited
      securities, as well as the fees and expenses of The Bank of New York;
 
    - production of satisfactory proof of the identity of the person presenting
      ordinary shares for deposit or ADSs upon withdrawal, and of the
      genuineness of any signature or other information they deem necessary; and
 
    - compliance with regulations The Bank of New York may establish consistent
      with the deposit agreement, including presentation of transfer documents.
 
                                      124
<PAGE>
    The Bank of New York may refuse to deliver, transfer, or register transfers
of ADSs generally when the transfer books of The Bank of New York are closed or
at any time if The Bank of New York or Vodafone AirTouch thinks it advisable to
do so.
 
PRE-RELEASE OF ADSS
 
    The Bank of New York may issue ADSs before deposit of the underlying
ordinary shares. This is called a pre-release of ADSs. The Bank of New York may
also deliver ordinary shares prior to the receipt and cancellation of
pre-released ADSs even if the ADSs are cancelled before the pre-release
transaction has been closed out. A pre-release is closed out as soon as the
underlying ordinary shares are delivered to The Bank of New York. The Bank of
New York may receive ADSs instead of ordinary shares to close out a pre-release.
The Bank of New York may pre-release ADSs only under the following conditions:
 
        (1) before or at the time of the pre-release, the person to whom the
    pre-release is being made must represent to The Bank of New York in writing
    that it or its customer, as the case may be,
 
           (a) owns the ordinary shares or ADSs to be remitted,
 
           (b) will assign all beneficial rights, title and interest in the ADSs
       or ordinary shares to The Bank of New York in its capacity as the
       depositary and for the benefit of the holders of the ADSs and
 
           (c) will not take any action with respect to the ADSs or ordinary
       shares that is inconsistent with the assignment of beneficial ownership
       (including, without the consent of The Bank of New York, disposing of the
       ADSs or ordinary shares) other than in satisfaction of the pre-release;
 
        (2) the pre-release must be fully collateralized with cash or collateral
    that The Bank of New York considers appropriate; and
 
        (3) The Bank of New York must be able to close out the pre-release on
    not more than five business days' notice.
 
    The pre-release will be subject to whatever indemnities and credit
regulations that The Bank of New York considers appropriate. In addition, The
Bank of New York will limit the number of ADSs that may be outstanding at any
time as a result of pre-release.

                 COMPARISON OF RIGHTS OF AIRTOUCH STOCKHOLDERS
                       AND VODAFONE AIRTOUCH SHAREHOLDERS
 
    As a result of the merger, holders of AirTouch common stock who do not
exercise their appraisal rights will receive Vodafone AirTouch ADSs, each
representing ten ordinary shares of Vodafone AirTouch, a company incorporated
under the laws of England and Wales. The following is a summary comparison of
material differences between the rights of an AirTouch stockholder and a
Vodafone AirTouch shareholder arising from the differences between the corporate
laws of Delaware and of England and Wales, the governing instruments of the two
companies, and the securities laws and regulations governing the two companies.
This summary assumes that all the changes which are proposed at the Vodafone
extraordinary general meeting are approved by Vodafone shareholders. However, it
is not a complete description of the laws of Delaware or of England and Wales,
the other rules or laws referred to in this summary, the AirTouch certificate of
incorporation, the AirTouch by-laws, the certificate of designations of the
AirTouch Class B preferred stock or the Vodafone AirTouch memorandum and
articles of association. For information as to where the governing instruments
of Vodafone, AirTouch and Vodafone AirTouch may be obtained, see "SUMMARY--
Where You Can Find More Information." You are encouraged to obtain and read
these documents.
 
    You should refer to "DESCRIPTION OF VODAFONE AIRTOUCH AMERICAN DEPOSITARY
SHARES" for a description of the Vodafone AirTouch ADSs and a discussion of the
ways in which the rights of holders of Vodafone AirTouch ADSs may differ from
those of holders of Vodafone AirTouch ordinary shares.

                               FEES AND EXPENSES
 
    Pursuant to the merger agreement, Vodafone and AirTouch have agreed to each
pay half of certain expenses. See "THE MERGER AGREEMENT--Expenses."
 
    Estimated fees and expenses incurred or to be incurred by Vodafone in
connection with the merger are approximately $200.0 million, which includes up
to approximately $110.0 million of bank arrangement and associated fees in
connection with the new credit facility which Vodafone and AirTouch entered into
on April 16, 1999. Estimated fees and expenses incurred or to be incurred by
AirTouch in connection with the merger are approximately $70.0 million.
 
    These fees and expenses related to the merger will be financed by the new
credit facility and from generally available funds of Vodafone and AirTouch. The
new facility will also provide the funds to pay the cash consideration in the
merger, refinance part of their existing indebtedness and to finance anticipated
working capital requirements of the combined entity.
 
    Neither Vodafone nor AirTouch will pay any fees or commissions to any broker
or dealer or any person other than Georgeson & Company Inc., Morgan Stanley &
Co. Incorporated and the Exchange Agent for soliciting AirTouch stockholders
pursuant to the merger. Upon request, AirTouch will reimburse brokers, dealers,
commercial banks and trust companies for reasonable and necessary costs and
expenses incurred by them in forwarding materials to their customers.
 
                             VALIDITY OF SECURITIES
 
    Stephen R. Scott, Company Secretary of Vodafone, will pass upon the validity
under English law of the Vodafone AirTouch ordinary shares to be issued pursuant
to the merger.

                          FUTURE STOCKHOLDER PROPOSALS
 
    If the merger is completed as expected, AirTouch will not hold an annual
meeting of AirTouch stockholders in 1999. If the merger is not approved by
AirTouch stockholders or is not completed for any other reason, AirTouch will
hold a 1999 annual meeting. Stockholder proposals submitted for inclusion in the
proxy statement for the 1999 annual meeting must comply with the requirements of
the SEC. A stockholder proposal generally will be voted on only if the
stockholder or the stockholder's representative attends the 1999 annual meeting
and presents the proposal. Any AirTouch stockholder who intended to submit a
proposal for inclusion in the proxy materials for the 1999 annual meeting was
required to have submitted his or her proposal to AirTouch's executive offices
at least 75 days prior to the meeting, unless less than 90 days' notice of the
date of the meeting is given to AirTouch stockholders, in which case the
proposal must be received by the earlier of 15 days following the day on which
notice or disclosure of the meeting was mailed or made, whichever comes first,
and two days prior to the date of the meeting.

    rights, privileges, immunities, powers and franchises, shall continue

    shares of Vodafone, of nominal value 5p each, ("VODAFONE ORDINARY SHARES")
    or, if the redenomination of Vodafone's ordinary share capital from pounds
    sterling into U.S. dollars (the "REDENOMINATION") is approved by the
    requisite vote of shareholders of Vodafone at the meeting convened for such
    purpose as contemplated by Section 3.4. and otherwise becomes effective, of
    nominal value US$.10 each (as such consideration may be adjusted pursuant to
    clause (y) or (z) below, the "STOCK CONSIDERATION"), and (ii) $9.00 in cash,
    without interest (as such consideration may be adjusted pursuant to clause
    (y) or (z) below, the "CASH CONSIDERATION", and, together with the Stock
    Consideration, the "MERGER CONSIDERATION"), PROVIDED, THAT, (y) if the 50%
    Test (as defined in Section 3.1.6.) has not been satisfied but the Private
    Letter Ruling (as defined in Section 3.1.7.) has been obtained, (i) the
    Exchange Ratio shall be reduced by the smallest amount (rounded to the
    nearest 1/1000th of a Vodafone Ordinary Share) which Fried, Frank, Harris,
    Shriver & Jacobson and Sullivan & Cromwell agree in writing is necessary to
    satisfy the 50% Test and (ii) the Cash Consideration shall be increased by
    the value of the fraction of a Vodafone Ordinary Share (based on a value of

    that (z) if the Private Letter Ruling has not been obtained, (i) the
    Exchange Ratio shall be reduced (provisionally, subject to clause (z)(iv)
    and (z)(v) below) by the smallest amount (rounded to the nearest 1/1000th of
    a Vodafone Ordinary Share) which Fried, Frank, Harris, Shriver & Jacobson

    set forth in U.S. Treasury Regulation Section 1.367(a)-3(c)(3)(iii) without
    obtaining the Private Letter Ruling, (ii) the Cash Consideration shall be
    reduced to $0, (iii) in lieu of the Cash Consideration, AirTouch shall,
    immediately prior to Closing, pay to each holder of AirTouch Common Shares
    an amount in cash for each AirTouch Common Share held by such stockholder
    equal to the sum of $9.00 plus the value of the fraction of a Vodafone
    Ordinary Share (based on a value of $17.60 per Vodafone Ordinary Share)
    represented by the reduction in the Exchange Ratio pursuant to the foregoing
    clause (z)(i) (such amount, the "AIRTOUCH CASH PAYMENT"), (iv) if AirTouch
    elects to make the AirTouch Cash Payment by means of a pro rata dividend,
    the Exchange Ratio shall be as determined in accordance with clause (z)(i),
    and (v) if AirTouch elects to make the AirTouch Cash Payment by means of a
    pro rata stock redemption, the Exchange Ratio shall be equal to (A) the
    number of AirTouch Common Shares outstanding immediately prior to the
    Effective Time but prior to the pro rata stock redemption, other than
    Excluded AirTouch Shares and Dissenting Shares (the "OUTSTANDING NUMBER")
    multiplied by (B) the provisional Exchange Ratio determined pursuant to
    clause (z)(i) divided by (C) the Outstanding Number minus the number of
    AirTouch Common Shares redeemed in the pro rata redemption. If AirTouch
    elects to make the AirTouch Cash Payment by means of a pro rata stock
    redemption, it shall establish the procedures, including an appropriate
    amendment to its certificate of incorporation, by which such redemption
    shall be effected.
 
                                      A-2
<PAGE>
        For all purposes of this Agreement, the Cash Consideration shall not be
    deemed to include the AirTouch Cash Payment. In no circumstance will the
    Cash Consideration or the AirTouch Cash Payment exceed $13.00 per AirTouch
    Common Share without the prior consent, at its sole discretion, of the board
    of directors of Vodafone (any such consent, the "INCREASED CASH CONSENT").
    If AirTouch is required to make the AirTouch Cash Payment, it shall also
    make a payment to holders of Class C Preferred Shares (as defined in Section
    1.3.6.3.1.3.) on a pro rata basis with the payment made to holders of
    AirTouch Common Shares based on the Exchange Rate (as that term is defined
    in the Class C Certificate of Designation (as defined in Section
    1.3.6.3.1.3.)) in effect on the date immediately preceding such cash
    payment.
 
        Any Vodafone Ordinary Shares constituting a portion of the Merger
    Consideration shall be delivered to the holders of AirTouch Common Shares
    (other than Excluded AirTouch Shares and Dissenting Shares) in the form of
    American depositary shares, each representing the right to receive ten
    Vodafone Ordinary Shares (the "VODAFONE DEPOSITARY SHARES"). The Vodafone
    Depositary Shares may be evidenced by one or more receipts ("VODAFONE ADRS")
    issued in accordance with the Amended and Restated Deposit Agreement, dated
    as of September 16, 1991, among Vodafone, The Bank of New York, as
    Depositary (the "DEPOSITARY"), and the holders from time to time of Vodafone
    ADRs, as amended and restated as of the date on which the Effective Time
    occurs (the "DEPOSIT AGREEMENT").
 
        At the Effective Time, all AirTouch Common Shares shall no longer be
    outstanding, shall be canceled and retired and shall cease to exist, and
    each certificate (a "CERTIFICATE") formerly representing any of such
    AirTouch Common Shares (other than Excluded AirTouch Shares and Dissenting
    Shares) shall thereafter represent only the right to the Merger
    Consideration and the AirTouch Cash Payment, if any, and the right, if any,
    to receive pursuant to Section 1.6. cash in lieu of fractional Vodafone
    Depositary Shares, and any dividend or distribution pursuant to Section
    1.4.6., in each case without interest. The Vodafone Ordinary Shares issued
    in accordance with Section 1.4.1., and the Vodafone Depositary Shares issued
    as provided in this Section 1.3.2., shall be of the same class and shall
    have the same rights as the currently outstanding Vodafone Ordinary Shares
    and the currently outstanding Vodafone Depositary Shares, respectively
    (other than in relation to the nominal value of all Vodafone Ordinary
    Shares, which may be US$.10 each, PROVIDED, THAT, the Redenomination takes
    effect). At and following the Closing, Vodafone and AirTouch shall be
    jointly and severally liable for all stamp duties, stamp duty reserve tax
    and other similar taxes and similar levies imposed in connection with the
    issuance or creation of the Vodafone Depositary Shares constituting the
    Stock Consideration or issued in respect of the conversion of any AirTouch
    Stock Options (as defined in Section 1.5.) pursuant to Section 1.5. and any
    Vodafone Depositary Shares in connection therewith and any other United
    Kingdom stamp duty, stamp duty reserve tax or other similar United Kingdom
    governmental charge (or any interest or penalties thereon) that may be
    payable by Vodafone and AirTouch pursuant to the Deposit Agreement.
 
        1.3.3.  Each share of common stock of Merger Sub, no par value ("MERGER
    SUB COMMON STOCK"), outstanding immediately prior to the Effective Time
    shall be canceled and, in consideration for the issuance, in accordance with
    Section 1.4.1., of the Vodafone Ordinary Shares referred to in Section
    1.3.4. below, the Surviving Corporation shall issue to Vodafone at the
    Effective Time such number of shares of common stock as is equal to the
    number of AirTouch Common Shares outstanding immediately prior to the
    Effective Time (other than the Excluded AirTouch Shares and Dissenting
    Shares) with the same rights, powers and privileges as the AirTouch Common
    Shares and shall constitute the only outstanding shares of common stock of
    the Surviving Corporation.
 
        1.3.4.  In consideration of the issue to Vodafone by the Surviving
    Corporation of shares of common stock of the Surviving Corporation pursuant
    to Section 1.3.3. hereof, Vodafone shall issue,
 
                                      A-3
<PAGE>
    in accordance with Section 1.4.1., such number of Vodafone Ordinary Shares
    as is equal to the number of AirTouch Common Shares outstanding immediately
    prior to the Effective Time (other than the Excluded AirTouch Shares and the
    Dissenting Shares) multiplied by the Exchange Ratio to permit the issuance
    of Vodafone Depositary Shares to the holders of such AirTouch Common Shares
    and shall pay the Cash Consideration for the purpose of giving effect to the
    delivery of the Merger Consideration referred to in Section 1.3.2. of this
    Agreement.
 
        1.3.5.  In the event that, subsequent to the date of this Agreement but
    prior to the Effective Time, AirTouch changes the number of AirTouch Common
    Shares, or Vodafone changes the number of Vodafone Ordinary Shares, issued
    and outstanding as a result of a stock split, combination, stock dividend,
    recapitalization, redenomination of share capital (other than the
    Redenomination) or other similar transaction, the Exchange Ratio and other
    items dependent thereon shall be appropriately adjusted.
 
        1.3.6.  AIRTOUCH PREFERRED STOCK
 
           1.3.6.1.  Prior to the Effective Time, subject to the stockholder
       approval described in Section 1.3.6.2., AirTouch will cause AirTouch
       Merger Sub, Inc., a newly-formed, wholly owned subsidiary of AirTouch, to
       merge with and into AirTouch (the "INITIAL MERGER"), with AirTouch being
       the surviving corporation (the "INITIAL SURVIVING CORPORATION").
 
           1.3.6.2.  AirTouch will take, or cause to be taken, all action
       necessary to submit to the vote of the holders of AirTouch Common Shares

       Stock, Series 1996, of AirTouch (the "CLASS B PREFERRED STOCK"), voting

       the effective time of the Initial Merger (the "INITIAL MERGER EFFECTIVE
       TIME"), mean (and be deemed to refer to) the Initial Surviving
       Corporation and all references to AirTouch Common Shares, shall, after
       the Initial Merger Effective Time, mean (and be deemed to refer to)
       common shares of the Initial Surviving Corporation (the "INITIAL

               Corporation.
 
                   1.3.6.3.2.5.  Each Class E Preferred Share of the Initial
               Surviving Corporation outstanding immediately prior to the
               Effective Time (other than Dissenting Shares), shall remain
               outstanding as a Class E Preferred Share of the Surviving
               Corporation.
 
    1.4.  SURRENDER AND PAYMENT.
 
        1.4.1.  Prior to the Effective Time, Vodafone shall appoint ChaseMellon
    Shareholder Services, L.L.C. or, failing ChaseMellon Shareholder Services,
    L.L.C., another agent reasonably acceptable to AirTouch as exchange agent
    (the "EXCHANGE AGENT") for the purpose of exchanging Certificates for
    Vodafone Depositary Shares and the Cash Consideration. Promptly after the
    Effective Time, the Surviving Corporation will send, or will cause the
    Exchange Agent to send, to each holder of record as of the Effective Time of
    AirTouch Common Shares (other than holders of Excluded AirTouch Shares and
    Dissenting Shares), a letter of transmittal, in such form as AirTouch and
    Vodafone may reasonably agree, for use in effecting delivery of AirTouch
    Common Shares to the Exchange Agent. AirTouch shall act as agent for each
    holder of record as of the Effective Time of AirTouch Common Shares (other
    than Excluded AirTouch Shares and Dissenting Shares) (each, a "RECORD
    HOLDER") and shall enter into an agreement (the "NOMINEE AGREEMENT") with
    Vodafone and Boston EquiServe Limited Partnership. Vodafone shall issue the
    Vodafone Ordinary Shares referred to in Section 1.3.4. in registered form to
    Boston EquiServe Limited Partnership or its nominee (the "NOMINEE"), as
    nominee and agent for and on behalf of the Record Holders for the issuance
    of Vodafone Depositary Shares in accordance with this Article I, subject to
    the terms and conditions of this Agreement and the Nominee Agreement. If the
    Redenomination shall take effect immediately prior to the Effective Time,
    then, unless the directors of Vodafone shall determine not to issue Bearer
    Shares (as defined below), the Nominee shall, as agent for the Record
    Holders, instruct Vodafone to, and Vodafone shall, strike the name of the
    Nominee from the Vodafone Shareholders' register, create share warrants to
    bearer ("BEARER SHARES") in respect of such Vodafone Ordinary Shares and
    deliver the Bearer Shares to the Nominee, as agent as aforesaid. Regardless
    of whether the Redenomination takes effect and the Bearer Shares are
    delivered to the Nominee, the Vodafone Ordinary Shares in registered form or
    the Bearer Shares, as the case may be, held by the Nominee shall be
    deposited by the Nominee or on its behalf with
 
                                      A-6
<PAGE>
    the Depositary (or as it may direct) as and when required for the issuance
    of Vodafone Depositary Shares in accordance with this Article I. To the
    extent required, the Exchange Agent will requisition from the Depositary,
    from time to time, such number of Vodafone Depositary Shares, in such
    denominations as the Exchange Agent shall specify, as are issuable in
    respect of AirTouch Common Shares properly delivered to the Exchange Agent.
    Vodafone shall from time to time deposit or cause to be deposited cash in an
    amount sufficient to provide the Exchange Agent with the cash to fund the
    payments to be paid by Vodafone required by Section 1.4.2.
 
        1.4.2.  Each holder of any AirTouch Common Shares that have been
    converted into a right to receive the consideration set forth in Section
    1.3.2. shall, upon surrender to the Exchange Agent of a Certificate or
    Certificates, together with a properly completed letter of transmittal
    covering the AirTouch Common Shares represented by such Certificate or
    Certificates, without further action, be entitled to receive (i) the number
    of whole Vodafone Depositary Shares included in the Merger Consideration in
    respect of such AirTouch Common Shares, and (ii) a check in the amount
    (after giving effect to any required tax withholdings) of (A) the Cash
    Consideration that such holder has the right to receive pursuant to Section
    1.3.2., plus (B) any cash in lieu of fractional shares to be paid pursuant
    to Section 1.6., plus (C) any cash dividends or other distributions that
    such holder has the right to receive pursuant to Section 1.4.6. Until so
    surrendered, each such Certificate shall after the Effective Time represent
    for all purposes only the right to receive the number of whole Vodafone
    Depositary Shares included in the Merger Consideration and the applicable
    amounts of cash provided in the foregoing clause (ii).
 
        1.4.3.  If any Vodafone Depositary Shares are to be issued to a person
    other than the registered holder of the AirTouch Common Shares represented
    by a Certificate or Certificates surrendered with respect thereto, it shall
    be a condition to such issue that the Certificate or Certificates so
    surrendered shall be properly endorsed or otherwise be in proper form for
    transfer and that the person requesting such issue shall pay to the Exchange
    Agent any transfer or other taxes required as a result of such issue to a
    person other than the registered holder of such AirTouch Common Shares or
    establish to the satisfaction of the Exchange Agent that such tax has been
    paid or is not payable.
 
        1.4.4.  After the close of the stock transfer books of AirTouch on the
    day prior to the Effective Time, there shall be no further registration of
    transfers of AirTouch Common Shares that were outstanding prior to the
    Effective Time. After the Effective Time, Certificates presented to the
    Surviving Corporation for transfer shall be canceled and exchanged for the
    consideration provided for, and in accordance with the procedures set forth,
    in this Article I.
 
        1.4.5.  Any Vodafone Ordinary Shares issued and delivered in respect of
    AirTouch Common Shares pursuant to this Article I, any cash entitled to be
    received therefor pursuant to Section 1.3.2., and any cash in lieu of
    fractional interests in Vodafone Depositary Shares to be paid pursuant to
    Section 1.6., plus any cash dividend or other distribution that such holder
    has the right to receive pursuant to Section 1.4.6., that remains unclaimed
    by any holder of AirTouch Common Shares six months after the Effective Time
    shall be held by the Exchange Agent (or a successor agent appointed by
    Vodafone) or shall be delivered to the Depositary upon the instruction of
    Vodafone and held by the Depositary, in either case subject to the
    instruction of Vodafone in an account or accounts designated for such
    purpose. Vodafone shall not be liable to any holder of AirTouch Common
    Shares for any securities delivered or any amount paid by the Depositary,
    the Exchange Agent or its nominee, as the case may be, to a public official
    pursuant to applicable abandoned property laws. Any cash remaining unclaimed
    by holders of AirTouch Common Shares three years after the Effective Time
    (or such earlier date immediately prior to such time as such cash would
    otherwise escheat to or become property of any governmental entity or as is
    otherwise provided by applicable Law (as defined in Section 2.1.4.2.))
    shall, to the extent permitted by
 
                                      A-7
<PAGE>
    applicable Law, become the property of the Surviving Corporation or
    Vodafone, as Vodafone may determine.
 
        1.4.6.  No dividends or other distributions with respect to securities
    of Vodafone issuable with respect to AirTouch Common Shares shall be paid to
    the holder of any unsurrendered Certificates until such Certificates are
    surrendered as provided in this Section. Subject to the effect of applicable
    Law, upon such surrender, there shall be issued and/or paid to the holder of
    the Vodafone Depositary Shares issued in exchange therefor, without
    interest, (A) at the time of such surrender, the dividends or other
    distributions payable with respect to such Vodafone Depositary Shares with a
    record date after the Effective Time and a payment date on or prior to the
    date of such surrender and not previously paid and (B) at the appropriate
    payment date, the dividends or other distributions payable with respect to
    such Vodafone Depositary Shares with a record date after the Effective Time
    but with a payment date subsequent to such surrender. For purposes of
    dividends or other distributions in respect of Vodafone Depositary Shares,
    all Vodafone Depositary Shares to be issued pursuant to the Merger shall be
    deemed issued and outstanding as of the Effective Time.
 
    1.5.  AIRTOUCH STOCK OPTIONS.
 
        1.5.1.  At the Effective Time, all stock options to purchase AirTouch
    Common Shares (each, an "AIRTOUCH STOCK OPTION") and tandem stock
    appreciation rights ("TANDEM SARS"), whether vested or unvested, which are
    then outstanding and unexercised shall cease to represent a right to acquire
    AirTouch Common Shares and shall be converted automatically into options to
    purchase, and tandem stock appreciation rights with respect to, Vodafone
    Ordinary Shares, and Vodafone shall assume each such AirTouch Stock Option
    and Tandem SAR, subject to the terms of the relevant AirTouch Stock Plan (as
    defined in Section 2.1.2.1.) under which it was issued and the agreement
    evidencing the grant thereof; provided, however, that from and after the
    Effective Time, (i) the number of Vodafone Ordinary Shares purchasable upon
    exercise of each such AirTouch Stock Option or subject to a Tandem SAR shall
    be equal to the number of AirTouch Common Shares that were purchasable under
    such AirTouch Stock Option or subject to such Tandem SAR immediately prior
    to the Effective Time multiplied by the Exchange Ratio, subject to
    adjustment as provided in Section 1.3.5., and rounding down to the nearest
    whole Vodafone Ordinary Share (or, if issued in the form of Vodafone
    Depositary Shares, the nearest whole Vodafone Depositary Share), and (ii)
    the per Vodafone Ordinary Share exercise price under each such AirTouch
    Stock Option or Tandem SAR shall be obtained by dividing (A) the per share
    exercise price of each such AirTouch Stock Option or Tandem SAR less the per
    share Cash Consideration or AirTouch Cash Payment, as the case may be, by
    (B) the Exchange Ratio, subject to adjustment as provided in Section 1.3.5.,
    and rounding down to the nearest cent. Vodafone Ordinary Shares to be issued
    upon the exercise of AirTouch Stock Options or Tandem SARs shall, at the
    election of the holders of such AirTouch Stock Options or Tandem SARs, be
    delivered in the form of Vodafone Depositary Shares evidenced by Vodafone
    ADRs. Notwithstanding the foregoing, the number of Vodafone Ordinary Shares
    and the per Vodafone Ordinary Share exercise price of each AirTouch Stock
    Option which is intended to be an "INCENTIVE STOCK OPTION" (as defined in
    Section 422 of the U.S. Code) shall be adjusted in accordance with the
    requirements of Section 424 of the U.S. Code. At or prior to the Effective
    Time, AirTouch shall make all necessary arrangements with respect to the
    AirTouch Stock Plans to permit the assumption by Vodafone of any unexercised
    AirTouch Stock Options and Tandem SARs.
 
        1.5.2.  Prior to the Effective Time, Vodafone shall make available for
    issuance in accordance with Section 1.4.1. the number of Vodafone Ordinary
    Shares necessary to satisfy Vodafone's obligations under Section 1.5.1. and
    1.5.3. As soon as practicable after the Effective Time, Vodafone shall file
    with the Securities and Exchange Commission (the "SEC") a registration
    statement on an appropriate form or a post-effective amendment to a
    previously filed registration
 
                                      A-8
<PAGE>
    statement under the Securities Act of 1933, as amended (the "SECURITIES
    ACT"), with respect to the Vodafone Ordinary Shares and the Vodafone
    Depositary Shares issued pursuant to Section 1.5.1. or Section 1.5.3., and
    shall use its best reasonable efforts to cause such registration statement
    to become and remain effective and maintain the current status of the
    prospectus contained therein, as well as comply with any applicable state
    securities or "BLUE SKY" laws, for so long as such options or other awards
    remain outstanding.
 
        1.5.3.  At the Effective Time, each other right with respect to the
    AirTouch Common Shares (an "AIRTOUCH AWARD"), whether vested or unvested,
    shall be deemed to constitute a right to receive or acquire, on the same
    terms and conditions as were applicable under the AirTouch Award, the same
    number of Vodafone Ordinary Shares as the holder of such AirTouch Award
    would have been entitled to receive pursuant to the Merger had such holder
    received such AirTouch Award in full immediately prior to the Effective Time
    (rounded to the nearest whole number), in each case, as appropriately
    adjusted to reflect the payment of the Cash Consideration or the AirTouch
    Cash Payment, as the case may be. Effective at the Effective Time, Vodafone
    shall assume each AirTouch Award in accordance with the terms of the
    relevant AirTouch Stock Plan under which it was issued and the award
    agreement by which it was evidenced. At or prior to the Effective Time,
    Vodafone shall take all corporate action necessary to reserve for issuance a
    sufficient number of Vodafone Ordinary Shares with respect to the AirTouch
    Awards assumed by it in accordance with this Section 1.5.3.
 
    1.6.  FRACTIONAL VODAFONE DEPOSITARY SHARES.  No fraction of a Vodafone
Depositary Share will be issued, but in lieu thereof each holder of AirTouch
Common Shares otherwise entitled to receive a fraction of a Vodafone Depositary
Share will be entitled to receive in accordance with the provisions of this
Section 1.6. from the Exchange Agent a cash payment in lieu of such fraction of
a Vodafone Depositary Share representing such holder's proportionate interest in
the net proceeds from the sale by the Exchange Agent on behalf of all such
holders of the aggregate of the fractions of Vodafone Depositary Shares which
would otherwise be issued ("EXCESS SHARES"). The sale of the Excess Shares by
the Exchange Agent shall be executed on the New York Stock Exchange, Inc. (the
"NYSE") through one or more member firms of the NYSE and shall be executed in
round lots to the extent practicable. Until the net proceeds of such sale or
sales have been distributed to the holders of AirTouch Common Shares, the
Exchange Agent will hold such proceeds in trust for the holders of AirTouch
Common Shares (the "COMMON SHARES TRUST"). Vodafone shall pay all commissions,
transfer taxes and other out-of-pocket transaction costs, including the expenses
and compensation, of the Exchange Agent incurred in connection with such sale of
the Excess Shares. The Exchange Agent shall determine the portion of the Common
Shares Trust to which each holder of AirTouch Common Shares shall be entitled,
if any, by multiplying the amount of the aggregate net proceeds comprising the
Common Shares Trust by a fraction the numerator of which is the amount of the
fractional Vodafone Depositary Share interest to which such holder of AirTouch
Common Shares is entitled and the denominator of which is the aggregate amount
of fractional share interests to which all holders of AirTouch Common Shares are
entitled. As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of AirTouch Common Shares in lieu of any
fractional Vodafone Depositary Share interests, the Exchange Agent shall make
available such amounts to such holders of AirTouch Common Shares without
interest.
 
    1.7.  THE SURVIVING CORPORATION.
 
        1.7.1.  The certificate of incorporation of AirTouch in effect at the
    Effective Time shall be the certificate of incorporation of the Surviving
    Corporation until amended in accordance with applicable law.
 
        1.7.2.  The bylaws of AirTouch in effect at the Effective Time shall be
    the bylaws of the Surviving Corporation until amended in accordance with
    applicable law.
 
                                      A-9
<PAGE>
        1.7.3.  From and after the Effective Time, until successors are duly
    elected or appointed and qualified in accordance with applicable law, (i)
    the directors of the Surviving Corporation shall comprise six directors,
    three selected by the current Chief Executive Officer of Vodafone and three
    selected by the current Chief Executive Officer of AirTouch, and (ii) such
    officers as are mutually agreed by Vodafone and AirTouch prior to the
    Effective Time shall be the officers of the Surviving Corporation.
 
    1.8.  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificate
shall have been lost, stolen or destroyed, upon the holder's compliance with the
replacement requirements established by the Exchange Agent, including, if
necessary, the posting by such Person (as defined in Section 2.1.1.) of a bond
in customary amount as indemnity against any claim that may be made against it
with respect to such Certificate, the Exchange Agent will issue in exchange for
such lost, stolen or destroyed Certificate, the Merger Consideration and any
cash payable in lieu of fractional Vodafone Depositary Shares and any unpaid
dividends or other distributions deliverable pursuant to Section 1.4.6. in
respect of the AirTouch Common Shares represented by such Certificate pursuant
to this Agreement.
 
    1.9.  RESERVATION OF RIGHT TO REVISE TRANSACTION.  Without prejudice to
Section 1.3.2., in the event of any change in law in relation to stamp duty or
stamp duty reserve tax which materially increases the costs of the issuance or
creation of the Vodafone Ordinary Shares or the Vodafone Depositary Shares
issued or created as part of the Stock Consideration or in respect of the
conversion of any AirTouch Stock Options pursuant to Section 1.5., Vodafone
shall, subject as provided below, be entitled to change its domicile to a
jurisdiction other than the U.K. Such change may be effected in such manner as
Vodafone considers appropriate, including by the imposition of a new holding
company which acquires all of the outstanding and issued shares in Vodafone in
exchange for its own shares and is then substituted for Vodafone for the
purposes of this Agreement. For this purpose Vodafone may seek such approvals
from, and propose such resolutions to, its shareholders (and if applicable the
courts) as may be necessary to effect such change; provided always that, save
with the consent of AirTouch, no such change of domicile may be undertaken if
the effect would be likely to increase any liability for taxation on AirTouch or
its stockholders or holders of AirTouch Stock Options, Tandem SARs or AirTouch
Awards from that which would apply if no such change of domicile were to occur.
 
    1.10.  DISSENTING SHARES.  (a) AirTouch Common Shares (unless no Cash
Consideration is paid hereunder) and shares of Class D Preferred Shares and
Class E Preferred Shares which are issued and outstanding immediately prior to
the Effective Time and which are held by a holder who has not voted such shares
in favor of the Merger, who shall have delivered a written demand for appraisal
of such shares in the manner provided by the DGCL and who, as of the Effective
Time, shall not have effectively withdrawn or lost such right to appraisal
("DISSENTING SHARES") shall be entitled to such rights (but only such rights) as
are granted by Section 262 of the DGCL. Each holder of Dissenting Shares who
becomes entitled to payment for such Dissenting Shares pursuant to Section 262
of the DGCL shall receive payment therefor from the Surviving Corporation in
accordance with the DGCL; provided, however, that (i) if any such holder of
Dissenting Shares shall have failed to establish his entitlement to appraisal
rights as provided in Section 262 of the DGCL, (ii) if any holder of Dissenting
Shares shall have effectively withdrawn his demand for appraisal of such Shares
or lost his right to appraisal and payment for his Shares under Section 262 of
DGCL or (iii) if neither any holder of Dissenting Shares nor the Surviving
Corporation shall have filed a petition demanding a determination of the value
of all Dissenting Shares within the time provided in Section 262 of the DGCL,
such holder shall forfeit the right to appraisal of such Dissenting Shares and
each such Dissenting Share shall, in the case of AirTouch Common Shares, be
converted and exchanged pursuant to Section 1.3.2., or in the case of Class D or
Class E Preferred Shares, remain outstanding in accordance with Sections
1.3.6.3.2.4. and 1.3.6.3.2.5., respectively. AirTouch shall give Vodafone prompt
notice of any demands received by AirTouch for appraisal of AirTouch Common
Shares, shares of Class D Preferred Shares and Class E
 
                                      A-10
<PAGE>
Preferred Shares and Vodafone shall have the right to conduct all negotiations
and proceedings with respect to such demands.
 
    (b) Any and all amounts paid by AirTouch to holders of Dissenting Shares
shall be paid by AirTouch solely out of its own cash on hand or out of its own
borrowings. In no event shall Vodafone or its Affiliates (as defined in Section
2.1.1.) provide directly or indirectly any funds to AirTouch in respect of
payments of holders of Dissenting Shares or the repayment of any such
borrowings.
 
                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES
 
    2.1.  REPRESENTATIONS AND WARRANTIES OF AIRTOUCH AND VODAFONE.  Except as
set forth in the corresponding sections or subsections of the disclosure letter,
dated the date hereof and signed by an authorized officer, delivered by AirTouch
to Vodafone or by Vodafone to AirTouch (each a "DISCLOSURE LETTER," and the
"AIRTOUCH DISCLOSURE LETTER" and the "VODAFONE DISCLOSURE LETTER,"
respectively), as the case may be, or as disclosed in the AirTouch Reports (as
defined in Section 2.1.5.1.) or the Vodafone Reports (as defined in Section
2.1.5.2.) publicly available prior to the date hereof, AirTouch (except for
subparagraphs 2.1.2.2, 2.1.3.2, 2.1.5.2, 2.1.9(ii), 2.1.10.2, 2.1.11 and
2.1.14.2 below and references in paragraph 2.1.1 below to documents made
available by Vodafone to AirTouch) hereby represents and warrants to Vodafone,
and Vodafone (except for subparagraphs 2.1.2.1, 2.1.3.1, 2.1.5.1, 2.1.8,
2.1.9(i), 2.1.10.1, 2.1.14.1 and 2.1.16 below and references in paragraph 2.1.1

        2.1.1.  ORGANIZATION, GOOD STANDING AND QUALIFICATION.  Each of it and
    its Subsidiaries (as defined below) is duly organized, validly existing and

    of good standing) under the laws of its respective jurisdiction of
    organization and has all requisite corporate or similar power and authority,
    and has been duly authorized by all necessary approvals and orders, to own,
    operate and lease its properties and assets and to carry on its business as
    presently conducted and is duly qualified to do business and is in good
    standing in each jurisdiction where the ownership, operation or leasing of
    its assets or properties or conduct of its business requires such
    qualification, except where the failure to be so organized, qualified or in
    good standing, or to have such power or authority would not, individually or
    in the aggregate, reasonably be expected to have a Material Adverse Effect
    (as defined below) on it. AirTouch has made available to Vodafone complete
    and correct copies of its certificate of incorporation and by-laws, and
    Vodafone has made available to AirTouch complete and correct copies of its
    memorandum and articles of association, in all cases as amended to date.
    Such certificate of incorporation and by-laws or memorandum and articles of
    association, as the case may be, as so made available are in full force and
    effect.
 
        As used in this Agreement, the term (i) "SUBSIDIARY" means, with respect
    to AirTouch, any entity, whether incorporated or unincorporated, in which
    AirTouch owns, directly or indirectly, more than fifty percent of the
    securities or other ownership interests having by their terms ordinary
    voting power to elect more than fifty percent of the directors or other
    persons performing similar functions, or the management and policies of
    which AirTouch otherwise has the power to control, and, with respect to
    Vodafone, any body corporate which is a subsidiary or subsidiary
    undertaking, in each case within the meaning of the Companies Act of 1985 of
    the United Kingdom, as amended (the "COMPANIES ACT"), (ii) "MATERIAL ADVERSE
    EFFECT" means, with respect to any Person, a material adverse effect on the
    financial condition, properties, business, or results of operations of such
    Person and its Subsidiaries taken as a whole, PROVIDED, THAT, all references
    to Material Adverse Effect on Vodafone or its Subsidiaries or to AirTouch
    and its Subsidiaries in this Article II or in Article III shall be deemed to
    refer solely to Vodafone and its Subsidiaries and AirTouch and its
    Subsidiaries, respectively, without giving effect to Vodafone's ownership of
 
                                      A-11
<PAGE>
    AirTouch and its Subsidiaries after the Effective Time, (iii) "PERSON" means
    any individual, corporation (including not-for-profit), general or limited
    partnership, limited liability or unlimited liability company, joint
    venture, estate, trust, association, organization, Governmental Entity (as
    defined in paragraph 2.1.4.1 (Governmental Filings; No Violations)) or other
    entity of any kind or nature, and (iv) "AFFILIATE" has the meaning specified
    in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the
    "EXCHANGE ACT").
 
        2.1.2.  CAPITAL STRUCTURE.
 
           2.1.2.1.  The authorized capital stock of AirTouch consists of
       1,100,000,000 AirTouch Common Shares, of which 572,391,167 AirTouch
       Common Shares were issued and outstanding as of the close of business on
       December 31, 1998 and 4,373,383 shares were held in the treasury of
       AirTouch, and 60,000,000 shares of preferred stock, par value $.01 per
       share ( "AIRTOUCH PREFERRED SHARES"). Of such authorized AirTouch
       Preferred Shares, (i) 7,000,000 shares have been designated as the Series
       A Participating Preferred Stock, of which no shares are outstanding as of
       the date hereof but of which all have been reserved for issuance pursuant
       to the Rights Agreement, dated as of September 19, 1994 and as amended to
       the date hereof, between AirTouch and The Bank of New York, as rights
       agent (the "RIGHTS AGREEMENT"); (ii) 19,000,000 shares have been
       designated as Class B Preferred Shares, of which 17,197,235 shares were

       outstanding as of the date hereof and (v) 825,000 shares have been
       designated as Class E Preferred Shares, all of which shares are
       outstanding as of the date hereof. In addition, since December 31, 1998
       through the date hereof, AirTouch has issued no AirTouch Common Shares
       other than pursuant to previously outstanding options or convertible
       securities. All of the outstanding AirTouch Common Shares and AirTouch
       Preferred Shares have been duly authorized and validly issued and are
       fully paid and nonassessable. Other than as set forth above, AirTouch has
       no AirTouch Common Shares or AirTouch Preferred Shares reserved for or
       otherwise subject to issuance, except that (i) as of the close of
       business on December 31, 1998, there were 37,800,157 AirTouch Common
       Shares subject to issuance pursuant to AirTouch Stock Options outstanding
       under the plans of AirTouch identified in subparagraph 2.1.2.1 of the
       AirTouch Disclosure Letter as being the only compensation or benefit

       any matter.
 
           2.1.2.2.  The authorized share capital of Vodafone is L200,000,000
       divided into 4,000,000,000 ordinary shares of nominal value 5p each. As
       of the close of business on January 13, 1999, the allotted share capital
       of Vodafone consisted of 3,094,601,095 Vodafone Ordinary Shares. All of
       the outstanding Vodafone Ordinary Shares have been, and the Vodafone
       Ordinary Shares to be issued as Merger Consideration shall be, duly
       authorized and validly issued and are or will be, as the case may be,
       fully paid or credited as fully paid. Vodafone has no Vodafone Ordinary
       Shares reserved for or otherwise subject to issuance. Of the Vodafone
       Ordinary Shares described in the first sentence of this paragraph, as of
       the close of business on January 13, 1999, there were 2,230,470 Vodafone
       Ordinary Shares held by trusts operated by Vodafone Group Share Trustee

       Vodafone Disclosure Letter as being the only compensation or benefit
       plans or agreements pursuant to which Vodafone Ordinary Shares may be

       stock or other ownership interests of each of Vodafone's Significant
       Subsidiaries is duly authorized, validly issued, fully paid and
       nonassessable and owned by Vodafone or a direct or indirect wholly owned
       Subsidiary of Vodafone, in each case free and clear of any Encumbrance.

       no preemptive or other outstanding rights, options, warrants, conversion
       rights, stock appreciation rights, redemption rights, repurchase rights,

       acquire from Vodafone or any of its Subsidiaries, any securities of
       Vodafone or any of its Subsidiaries, and no securities or obligations
       evidencing such rights are authorized, issued or outstanding. Vodafone
       does not have outstanding any bonds, debentures, notes or other
       obligations the holders of which have the right to vote (or which are
       convertible into or exercisable for securities having the right to vote)
       with the shareholders of Vodafone on any matter.
 
           2.1.3.  CORPORATE AUTHORITY; APPROVAL AND FAIRNESS.
 
               2.1.3.1.  AirTouch has all requisite corporate power and
           authority and has taken all corporate action necessary in order to
           execute, deliver and perform its obligations under this Agreement and
           to consummate the Merger and the other transactions contemplated
           hereby (including, without limitation, the Initial Merger), subject
           only to the adoption of this Agreement and the Initial Merger by the
           vote of the holders of a majority of the outstanding stock entitled
           to vote at the AirTouch Shareholders Meeting (as defined in Section
           3.4. (Shareholders Meetings)) (the "AIRTOUCH REQUISITE VOTE"). The
           execution and delivery of this Agreement has been duly authorized by
           all necessary corporate action on the part of AirTouch and, assuming
           the due authorization, execution and delivery of this Agreement by
           Vodafone and Merger Sub, this Agreement constitutes a valid and
           binding agreement of AirTouch enforceable against AirTouch in
           accordance with its terms, subject to bankruptcy, insolvency,
           fraudulent transfer, reorganization, moratorium and similar laws of
           general applicability relating to or affecting creditors' rights and
           to general equity principles (the "BANKRUPTCY AND EQUITY EXCEPTION").
           The Board of Directors of AirTouch has (A) unanimously approved this
           Agreement, the Merger and the other transactions
 
                                      A-13

           contemplated hereby and declared their advisability and (B) has
           received the opinion of its financial advisor, Morgan Stanley & Co.
           Incorporated, to the effect that, as of the date of this Agreement,
           the Merger Consideration, together with the AirTouch Cash Payment, if
           any, is fair to the holders of AirTouch Common Shares from a
           financial point of view.
 
               2.1.3.2.  Vodafone has all requisite corporate power and
           authority and has taken all corporate action necessary in order to
           execute, deliver and perform its obligations under this Agreement and
           to consummate the Merger and the other transactions contemplated
           hereby, subject only to the approval of (i) the resolution set forth
           in clause (i) of the third sentence of Section 3.4. (the "VODAFONE
           REQUISITE RESOLUTION") by, on a show of hands, not less than a
           majority of the holders of the outstanding Vodafone Ordinary Shares
           present in person or, on a poll, by the holders of not less than a
           majority of the votes attaching to the Vodafone Ordinary Shares who
           vote in person or by proxy at the Vodafone Shareholders Meeting (as
           defined in Section 3.4. (Shareholders Meetings)) (the "VODAFONE
           REQUISITE VOTE") and (ii) the resolutions set forth in clauses (ii),
           (iii), (iv), (v) and (vi) of the third sentence of Section 3.4. (the
           "VODAFONE SUPPLEMENTAL RESOLUTIONS") by not less than three-fourths
           (or, in the case of such clauses (iii) and (v), a majority) of the
           persons voting on a show of hands or, on a poll, of the votes
           attaching to the Vodafone Ordinary Shares who vote in person or by
           proxy, at the Vodafone Shareholders Meeting (the "VODAFONE
           SUPPLEMENTAL VOTE"). The execution and delivery of this Agreement has
           been duly authorized by all necessary corporate action on the part of
           Vodafone, and, assuming the due authorization, execution and delivery
           of this Agreement by AirTouch, this Agreement constitutes a valid and
           binding agreement of Vodafone, enforceable against Vodafone in
           accordance with its terms, subject to the Bankruptcy and Equity
           Exception. The Board of Directors of Vodafone has (A) unanimously
           approved this Agreement, the Merger and the other transactions
           contemplated hereby and (B) received the opinion of its financial
           advisor, Goldman Sachs International, to the effect that, as of the
           date of this Agreement, the Merger Consideration, together with the
           AirTouch Cash Payment, if any, is fair, from a financial point of
           view, to Vodafone.

           normal year-end audit adjustments that will not be material in amount
           or effect), in each case in accordance with generally accepted
           accounting principles in the United States ("U.S. GAAP") consistently
           applied during the periods involved except as may be noted therein.
 
               2.1.5.2.  Vodafone has made available to AirTouch copies of (A)

           any Vodafone Reports filed, distributed or delivered subsequent to
           the date hereof will comply in all material respects with, any
           applicable requirements of the Securities Act and the Exchange Act
           and the rules and regulations of the SEC promulgated thereunder and

       respect of, in lieu of or in substitution for shares of its capital
       stock, except as expressly contemplated hereby; or (iv) any change by it
       in accounting principles, practices or methods except as required by
       changes in U.S. GAAP or U.K. GAAP, as the case may be. Since its
       respective Audit Date, except as provided for herein or as disclosed in
       the Reports filed prior to the date hereof, there has not been any
       material increase in the compensation payable or that could become
       payable by it or any of its Subsidiaries to officers or key employees or
       any amendment of any of its compensation or benefit plans or agreements
       other than increases or amendments in the ordinary course or as
       contemplated by this Agreement.
 
           2.1.7.  LITIGATION AND LIABILITIES.  Except as disclosed in the
       Reports filed prior to the date hereof, there are no (i) civil, criminal
       or administrative actions, suits, claims, hearings, investigations,
       complaints or proceedings pending or, to the knowledge of, in the case of
       AirTouch, its executive officers (as defined in the Exchange Act)
       ("AIRTOUCH OFFICERS"), and, in the case of Vodafone, its executive
       directors ("VODAFONE EXECUTIVE DIRECTORS"), threatened against it or any
       of its Subsidiaries (ii) obligations or liabilities, whether or not
       accrued, contingent or otherwise and whether or not required to be
       disclosed, or any other facts or circumstances of which, in the case of
       AirTouch, the AirTouch Officers, and, in the case of Vodafone, the
       Vodafone Executive Directors, have knowledge that would reasonably be
       expected to result in any claims against, or obligations or liabilities
       of, it or any of its Subsidiaries, except, in each case, for those that,
       individually or in the aggregate, have not had and would not reasonably
       be expected to have a Material Adverse Effect on it or prevent,
       materially delay or materially impair its ability to consummate the
       Merger and the other transactions contemplated by this Agreement.

           2.1.8.  TAKEOVER STATUTES.  The board of directors of AirTouch has
       taken or will take all appropriate and necessary action such that
       Vodafone will not be prohibited from entering into a "business
       combination" with AirTouch as an "interested stockholder" (in each case
       as such term is used in Section 203 of the DGCL) as a result of the
       execution and delivery of this Agreement or the consummation of the
       transactions contemplated hereby and thereby. No other "fair price,"
       "moratorium," "control share acquisition" or other similar anti-takeover
       statute or regulation, including such business combination provisions of
       the DGCL (each, a "TAKEOVER STATUTE"), and no anti-takeover provision in
       the certificate of incorporation or by-laws of AirTouch is, or at the
       Effective Time will be, applicable to the Merger or any of the other
       transactions contemplated by this Agreement.
 
           2.1.9.  BROKERS AND FINDERS.  Neither it nor any of its Subsidiaries,
       officers, directors or employees has employed any broker or finder or
       incurred any liability for any brokerage fees, commissions or finders'
       fees in connection with the execution and delivery of this Agreement, the
       Merger or the other transactions contemplated by this Agreement, except
       that (i) AirTouch has retained Morgan Stanley & Co. Incorporated as its
       financial advisor, the arrangements with which have been disclosed to
       Vodafone prior to the date hereof, and (ii) Vodafone has employed Goldman
       Sachs International as its financial advisor, the arrangements with which
       have been disclosed to AirTouch prior to the date hereof.
 
           2.1.10.  OWNERSHIP OF OTHER PARTY'S COMMON STOCK.
 
               2.1.10.1.  Neither AirTouch nor any of its Subsidiaries
           "beneficially owns" (as such term is defined in Rule 13d-3 under the
           Exchange Act) any Vodafone Ordinary Shares or Vodafone Depositary
           Shares.
 
               2.1.10.2.  Neither Vodafone nor any of its Subsidiaries
           "beneficially owns" (as such term is defined in Rule 13d-3 under the
           Exchange Act) any AirTouch Common Shares.
 
               2.1.11.  MERGER SUB'S OPERATIONS.  Merger Sub was formed solely
           for the purpose of engaging in the transactions contemplated hereby
           and has not (i) engaged in any business activities, (ii) conducted
           any operations other than in connection with the transactions
           contemplated hereby or (iii) incurred any liabilities other than in
           connection with the transactions contemplated hereby. The execution
           and delivery of this Agreement has been duly authorized by all
           necessary corporate action on the part of Merger Sub and, assuming
           the due authorization, execution and delivery of this Agreement by
           AirTouch, this Agreement constitutes a valid and binding agreement of
           Merger Sub enforceable against Merger Sub in accordance with its
           terms, subject to the Bankruptcy and Equity Exception. Vodafone, as
           Merger Sub's sole stockholder, has approved Merger Sub's execution of
           this Agreement.
 
               2.1.12.  ASSETS.  Each of it and its Subsidiaries has, and
           immediately after the Effective Time will have, good and valid title
           to its properties and assets, and valid and subsisting leasehold
           interests in all properties or assets of which it is lessee or
           licensee, in each case free and clear of any Encumbrances, except for
           such defects and Encumbrances which, individually or in the
           aggregate, have not had and would not reasonably be expected to have
           a Material Adverse Effect on it.
 
               2.1.13.  LICENSES.  Each of it, its Subsidiaries and, to the
           knowledge of the AirTouch Officers, in the case of AirTouch, or the
           Vodafone Executive Directors, in the case of Vodafone, its Affiliates
           has all material permits, licenses, certificates, waivers or
           authorizations ("LICENSES") from all Governmental Entities having
           jurisdiction over any part of its business necessary for the conduct
           of any of its activities, including, without limitation, licenses and
           authorizations from the FCC and certificates of public
 
                                      A-18
<PAGE>
           convenience and necessity from PUCs and OFTEL ("COMMUNICATIONS
           LICENSES") and all such material Licenses are valid and in full force
           and effect, except for any such Licenses the failure of which to have
           or to be in full force and effect would not, individually or in the
           aggregate, reasonably be expected to have a Material Adverse Effect.
           Neither it nor any of its Subsidiaries has made any untrue statement
           of material fact, nor has it omitted to disclose any material fact,
           to any Governmental Entity nor has it or any of its Subsidiaries
           taken or failed to take any action which misstatements, omissions,
           actions or failures to act, individually or in the aggregate, would
           subject or could reasonably be expected to subject any of the
           material Licenses held by it or any of its Subsidiaries to revocation
           or failure to renew or to the imposition of material conditions on
           any of such Licenses or the renewal thereof; and to the knowledge of
           the AirTouch Officers, in the case of AirTouch, or the Vodafone
           Executive Directors, in the case of Vodafone no event has occurred or
           other fact exists with respect to any of the material Licenses held
           by it or any of its Subsidiaries which permits, or after notice or
           lapse of time or both would permit, revocation or termination thereof
           or would result in any other material impairment of the rights of the
           holder of any of the material Licenses. There is no pending, or to
           the knowledge of, in the case of AirTouch, the AirTouch Officers, or,
           in the case of Vodafone, the Vodafone Executive Directors,
           threatened, application, complaint, petition, objection or other
           pleading with the FCC, OFTEL or other Governmental Entity which
           challenges or questions the validity of, or any rights of the holders
           under, any License held by AirTouch or any of its Subsidiaries or
           Vodafone or any of its Subsidiaries, as applicable, except for such
           applications, complaints, petitions, objections or other pleadings,
           that, individually or in the aggregate, have not had and would not
           reasonably be expected to have (taking into account both the
           likelihood of success and the likely relief) a Material Adverse
           Effect. It has no reason to believe that any such material License
           held by it or any of its Subsidiaries is not likely to be renewed in
           the ordinary course and without new material conditions or, in the
           case of such material U.S. Licenses, that the holder of any such
           License would not be entitled to a renewal expectancy as such term is
           defined in 47 C.F.R. section 22.941 or any successor provisions and
           associated FCC policies.
 
           2.1.14.  INTELLECTUAL PROPERTY.
 
               2.1.14.1.  AirTouch owns the entire right, title and interest in
           and to or has the right to use (pursuant to valid and defensible
           license arrangements), all Intellectual Property (as defined below)
           used or held for use in, or otherwise necessary for, the operation of
           its business as presently operated, except as would not, individually
           or in the aggregate, reasonably be expected to have a Material
           Adverse Effect. Except as provided in subparagraph 2.1.14 of the
           AirTouch Disclosure Letter, there are no pending, or to the knowledge
           of the AirTouch Officers, threatened proceedings or litigation or
           other adverse claims affecting or relating to any such Intellectual
           Property, nor, to the knowledge of the AirTouch Officers, any
           reasonable basis upon which a claim may be asserted by or against
           AirTouch for infringement of any such Intellectual Property that,
           individually or in the aggregate, would reasonably be expected to
           have a Material Adverse Effect on AirTouch's business as presently
           operated. As used herein, "INTELLECTUAL PROPERTY" means all
           industrial and intellectual property rights, including proprietary
           technology, patents, patent applications, trademarks, trademark
           applications and registrations, servicemarks, servicemark
           applications and registrations, trade dress, copyrights, know-how,
           licenses, trade secrets, proprietary processes, formulae and customer
           lists.

               2.1.14.2.  Vodafone owns the entire right, title and interest in
           and to or has the right to use (pursuant to valid and defensible
           license arrangements), all Intellectual Property used or held for use
           in, or otherwise necessary for, the operation of its business as
           presently operated, except as would not, individually or in the
           aggregate, reasonably be expected to have a Material Adverse Effect.
           Except as provided in subparagraph 2.1.14 of the Vodafone Disclosure
           Letter, there are no pending, or to the knowledge of the Vodafone
           Managing Directors, threatened proceedings or litigation or other
           adverse claims affecting or relating to any such Intellectual
           Property, nor, to the knowledge of the Vodafone Managing Directors,
           any reasonable basis upon which a claim may be asserted by or against
           Vodafone for infringement of any such Intellectual Property that,
           individually or in the aggregate, would reasonably be expected to
           have a Material Adverse Effect on Vodafone's business as presently
           operated.
 
           2.1.15.  YEAR 2000 COMPLIANCE.  To the knowledge of the AirTouch
       Officers, in the case of AirTouch and its Subsidiaries and the Vodafone
       Executive Directors, in the case of Vodafone and its Subsidiaries, (i) it
       and its Subsidiaries have taken steps that are reasonable to ensure that
       the occurrence of the year 2000 will not materially and adversely affect
       its and its Subsidiaries' information and business systems, (ii) as of
       the date hereof, no material expenditures in excess of currently budgeted
       items will be required to cause such systems to operate properly
       following the change of the year 1999 to the year 2000 and (iii) there is
       no fact or circumstance that would lead one to reasonably conclude that
       it will be unable to resolve any issues with respect to its mission
       critical systems arising in connection with the change from the year 1999
       to the year 2000 on a timely basis before the year 2000, except for such
       issues which, if not resolved, would not reasonably be likely to have a
       Material Adverse Effect on it.
 
           2.1.16.  RIGHTS PLAN.  AirTouch will take all necessary action with
       respect to all of the outstanding Rights so that, as of immediately prior
       to the Effective Time, (A) neither AirTouch nor Vodafone will have any
       obligations under the Rights or the Rights Agreement and (B) the holders
       of the Rights will have no rights under the Rights or the Rights
       Agreement.
 
           2.1.17.  JOINT VENTURES.  Set forth in subparagraph 2.1.17 of its
       Disclosure Letter is a list as of the date hereof of all material
       organizational documents, shareholder, partnership, membership, voting or
       joint venture agreements and agreements relating to existing restrictions
       on the transfer of investments to which it or its Subsidiaries is a party
       in connection with joint ventures in which the greater of the fair market
       value or book value of its or its Subsidiaries' investment in such joint
       venture exceeds $200 million ("JOINT VENTURE AGREEMENTS"). All of its
       Joint Venture Agreements are, with respect to it and its Subsidiaries,
       valid and in full force and effect on the date hereof except to the
       extent they have previously expired in accordance with their terms, or if
       the failure to be in full force and effect, individually or in the
       aggregate, would not reasonably be expected to have a Material Adverse
       Effect on it. Neither it nor any of its Subsidiaries has violated any
       provision of, or committed or failed to perform any act which with or
       without notice, lapse of time or both would constitute a default under
       the provisions of, any of its Joint Venture Agreements, except in each
       case for such as, individually or in the aggregate, would not reasonably
       be expected to result in a Material Adverse Effect on it; it being
       understood that no effect arising out of the execution, performance or
       consummation of this Agreement shall be deemed to have a Material Adverse
       Effect for purposes of this Section 2.1.17.
 
           2.1.18.  TAX MATTERS.  Neither it nor any of its Affiliates has taken
       or agreed to take any action that would, or failed to take any action the
       omission of which would, prevent or impede the Merger from qualifying as
       a reorganization under Section 368(a) of the U.S. Code.

       stock-based compensation or other benefits under, amend or otherwise
       modify any compensation or benefit plan or agreement or increase the
       salary, wage, bonus or other compensation of any directors, officers or

       private letter ruling (the "PRIVATE LETTER RULING") with respect to the
       transactions contemplated by the Agreement as described in United States
       Treasury Regulations Section 1.367(a)-3(c)(9); the preparation of such
       ruling request, and any oral or written communication with the Internal
       Revenue Service, shall be conducted jointly by Vodafone and AirTouch.
 
    3.2.  ACQUISITION PROPOSALS.
 
        3.2.1.  Each of AirTouch and Vodafone agrees that, subject to paragraph
    3.2.3 and except as expressly contemplated by this Agreement, neither it nor
    any of its Subsidiaries nor any of the officers or directors of it or its
    Subsidiaries shall, and that it shall direct and use its best reasonable
    efforts to cause its and its Subsidiaries' officers, directors, employees,
    investment bankers, attorneys, accountants, financial advisors, agents or
    other representatives (collectively, with respect to each of AirTouch and
    Vodafone, such Person's "REPRESENTATIVES") not to, directly or indirectly,
    initiate, solicit, encourage or otherwise facilitate any inquiries or the
    making of any proposal or offer with respect to a merger, reorganization,
    share exchange, dual-holding company transaction, consolidation or similar
    transaction involving AirTouch or Vodafone, or any purchase of, or offer to
    purchase, all or substantially all of the equity securities of AirTouch or
    Vodafone, as the case may be, or of its and its Subsidiaries' assets taken
    as a whole (any such proposal or offer being hereinafter referred to as an
    "ACQUISITION PROPOSAL"). Each of AirTouch and Vodafone further agrees that
    neither it nor any of its Subsidiaries nor any of its or its Subsidiaries'
    officers or directors shall, and that it shall direct and use its best
    reasonable efforts to cause its Representatives not to, directly or
    indirectly, have any discussions with or provide any confidential
    information or data to any Person relating to an Acquisition Proposal or
    engage in any negotiations concerning an Acquisition Proposal, or otherwise
    facilitate any effort or attempt to make or implement an Acquisition
    Proposal; PROVIDED, HOWEVER, that nothing contained in this Agreement shall
    prevent either AirTouch or Vodafone or its board of directors from (i)
    making any disclosure to its shareholders if, in the good faith judgment of
    its board of directors, failure so to disclose would be inconsistent with
    its obligations under applicable Law; (ii) negotiating with or furnishing
    information to any Person who has made a bona fide written Acquisition
    Proposal which did not result from a breach of this Section 3.2.1.; or (iii)
    recommending such an Acquisition Proposal to its shareholders, if and only
    to the extent that, in the case of actions referred to in clause (ii) or
    clause (iii), such Acquisition Proposal is a Superior Proposal (as defined
    below). For purposes of this Agreement, a "SUPERIOR PROPOSAL" means in
    respect of AirTouch or Vodafone, as applicable, any Acquisition Proposal by
    a third party (x) on terms which the board of directors of such Party
    determines in its good faith judgment, after consultation with its financial
    advisors (whose advice shall be communicated to the other Party), to be more
    favorable from a financial point of view to its stockholders, in the case of
    AirTouch, or its shareholders, in the case of Vodafone, than the Merger and
    the other transactions contemplated hereby after giving the other Party at
    least five business days notice of all material terms and conditions of such
    Acquisition Proposal to respond to such third party Acquisition Proposal and
    (y) which the board of directors of such Party determines in its good faith
    judgment to constitute a transaction that is reasonably likely to be
    consummated on the terms set forth, taking into account all legal,
    financial, regulatory and other aspects of such proposal. Each of AirTouch
    and Vodafone agrees that it will, on the date hereof, immediately cease and
    cause to be terminated any existing activities, discussions or negotiations
    with any Person conducted heretofore with respect to any Acquisition
    Proposal. Each of AirTouch and Vodafone also agrees that if it has not
    already done so, it will promptly request each Person, if any, that has
    heretofore executed a confidentiality agreement within the 12 months prior
    to the date hereof in connection with its consideration of any Acquisition
    Proposal to return or destroy all confidential information heretofore
    furnished to such Person by or on behalf of it or any of its Subsidiaries.

        3.2.2.  Each of AirTouch and Vodafone agrees that it will take the
    necessary steps promptly to inform its Subsidiaries and its and its
    Subsidiaries' Representatives of the obligations undertaken in this Section
    3.2. (Acquisition Proposals). Each of AirTouch and Vodafone agrees that it
    will notify the other promptly (and in any case within 24 hours) if any such
    inquiries, proposals or offers relating to or constituting an Acquisition
    Proposal are received by, any such information is requested from, or any
    such discussions or negotiations are sought to be initiated or continued
    with, any of its or its Subsidiaries' Representatives (such notice to
    include the name of the party making such inquiry, proposal, offer or
    request).
 
        3.2.3.  Nothing contained herein shall prohibit a Party from taking and
    disclosing to its shareholders a position contemplated by Rule 14d-9 or Rule
    14e-2(a) under the Exchange Act with respect to an Acquisition Proposal by
    means of a tender or exchange offer or, in the case of Vodafone, taking such
    action and making such recommendations as the directors of Vodafone
    reasonably consider necessary so as to comply with any obligations imposed
    on them or Vodafone by the City Code on Takeovers and Mergers (the "CITY
    CODE") or the Takeover Panel in relation to any Acquisition Proposal,
    provided that, it is hereby acknowledged, for the avoidance of doubt, that
    no provision of the City Code requires Vodafone or its directors to solicit
    or initiate any Acquisition Proposal.
 
    3.3.  INFORMATION SUPPLIED.
 
        3.3.1.  REGISTRATION STATEMENT.
 
           3.3.1.1.  Each of Vodafone and AirTouch shall cooperate and as
       promptly as practicable prepare and Vodafone shall file with the SEC as
       soon as practicable a Registration Statement on Form F-4 (the "FORM F-4")
       (or any successor form) under the Securities Act, with respect to the
       issuance pursuant to this Agreement of the Vodafone Ordinary Shares
       represented by Vodafone Depositary Shares, which Registration Statement
       shall include the proxy statement/ prospectus to be sent to holders of
       AirTouch Common Shares and Class B Preferred Shares (the "AIRTOUCH PROXY
       STATEMENT"). The Parties will cause the Form F-4 to comply as to form in
       all material respects with the applicable provisions of the Securities
       Act and the rules and regulations thereunder. Each of Vodafone and
       AirTouch shall use its respective best reasonable efforts to have the
       Form F-4 declared effective by the SEC as promptly as practicable after
       such filing. Vodafone shall use its reasonable efforts to obtain, prior
       to the effective date of the Form F-4, all necessary state securities law
       or "Blue Sky" permits or approvals required to carry out the transactions
       contemplated by this Agreement. Vodafone will advise AirTouch, promptly
       after it receives notice thereof, of the time when the Form F-4 has
       become effective or any supplement or amendment has been filed, the
       issuance of any stop order, the suspension of the qualification of the
       Vodafone Ordinary Shares represented by Vodafone Depositary Shares
       issuable in connection with the Merger for offering or sale in any
       jurisdiction, or any request by the SEC for amendment of the AirTouch
       Proxy Statement or the Form F-4 or comments thereon and responses thereto
       or requests by the SEC for additional information.
 
           3.3.1.2.  AirTouch and Vodafone each agrees, as to itself and its
       Subsidiaries, that none of the information supplied or to be supplied by
       it or its Subsidiaries for inclusion or incorporation by reference in the
       Form F-4, including, without limitation, the AirTouch Proxy Statement and
       any amendment or supplement thereto will, at the time the Form F-4
       becomes effective under the Securities Act, at the date of mailing to
       shareholders and at the time or times of the AirTouch Shareholders
       Meeting, contain any untrue statement of a material fact or omit to state
       any material fact required to be stated therein or necessary in order to
       make the statements therein, in the light of the circumstances under
       which they were made, not misleading. If at any time prior to the date of
       the AirTouch Shareholders Meeting any
 
                                      A-24
<PAGE>
       information relating to AirTouch or Vodafone, or any of their respective
       Affiliates, officers or directors, should be discovered by AirTouch or
       Vodafone which should be set forth in an amendment to the Form F-4 or a
       supplement to the AirTouch Proxy Statement, so that such document would
       not include any misstatement of a material fact or omit to state any
       material fact required to be stated therein or necessary to make the
       statements therein, in the light of the circumstances under which they
       were made, not misleading, the Party which discovers such information
       shall promptly notify the other Party and, to the extent required by Law,
       an appropriate amendment or supplement describing such information shall
       be promptly filed with the SEC and, to the extent required by law,
       disseminated to the AirTouch shareholders.
 
           3.3.1.3.  Each of Vodafone and AirTouch will use its best reasonable
       efforts to cause the Vodafone Documents (as defined in Section 3.3.2.)
       and the definitive AirTouch Proxy Statement, respectively, to be mailed
       to its shareholders as promptly as practicable after the date hereof.
 
        3.3.2.  AirTouch and Vodafone shall cooperate with respect to and
    Vodafone shall as promptly as practicable prepare and file with the LSE (a)
    a circular to be sent to Vodafone shareholders in connection with the
    Vodafone Shareholders Meeting (as defined in Section 3.4. (Shareholders
    Meetings)) (the "VODAFONE CIRCULAR"), containing (i) a notice convening the
    Vodafone Shareholders Meeting, (ii) such other information (if any) as may
    be required by the LSE and the City Code and (iii) such other information as
    Vodafone and AirTouch shall agree to include therein; and (b) listing
    particulars relating to Vodafone and its Subsidiaries and the Vodafone
    Ordinary Shares (the "VODAFONE LISTING PARTICULARS," and the Vodafone
    Circular and the Vodafone Listing Particulars together being the "VODAFONE
    DOCUMENTS"). AirTouch and Vodafone each agrees, as to itself and its
    Subsidiaries, that the Vodafone Documents and any supplements thereto and
    any other circulars or documents issued to shareholders, employees of
    Vodafone, will contain all particulars relating to AirTouch and Vodafone
    required to comply in all material respects with all United Kingdom
    statutory and other legal provisions (including, without limitation, the
    Companies Act, the Financial Services Act 1986 (the "FSA") and the rules and
    regulations made thereunder, and the rules and requirements of the LSE and
    the City Code) and all such information contained in such documents will be
    substantially in accordance with the facts and will not omit anything
    material likely to affect the import of such information.
 
    3.4.  SHAREHOLDERS MEETINGS.  AirTouch will take all action necessary to
convene a meeting of the holders of AirTouch Common Shares and Class B Preferred
Shares at which the holders of AirTouch Common Shares and AirTouch Class B
Preferred Shares shall consider adoption of this Agreement and the transactions
contemplated hereby (including, without limitation, the Initial Merger) (the
"AIRTOUCH SHAREHOLDERS MEETING") as promptly as practicable after the Form F-4
has been declared effective by the SEC. Vodafone will take all action necessary
to convene an extraordinary general meeting of holders of Vodafone Ordinary
Shares at which resolutions will be proposed to approve the Merger and the other
matters specified in the next succeeding sentence (the "VODAFONE SHAREHOLDERS
MEETING") as promptly as practicable after the Vodafone Documents are cleared by
the LSE and the Form F-4 has been declared effective by the SEC. Vodafone shall
propose at the Vodafone Shareholders Meeting referred to above the following
resolutions: (i) resolutions to approve all of the following transactions or
matters: (A) the Merger, (B) an increase in the authorized ordinary share
capital of Vodafone, and (C) the authorization of the Vodafone Board to allot
securities, including to AirTouch shareholders pursuant to the Merger; (ii)
resolutions to approve amendments to the Vodafone Articles of Association to

Plan and Vodafone AirTouch Long Term Incentive Plan and other compensation or
benefits for employees overseas which are based on the Vodafone AirTouch Share
Option Plan or the Vodafone AirTouch Long Term Incentive Plan; and (vi)
resolutions to amend the Vodafone Articles of Association to provide for the
delivery of notice of Vodafone Board meetings to Directors outside the U.K., to
provide for the appointment of multiple proxies by certain types of
shareholders, to provide that the Chairman of the Board of Directors shall not
have the casting vote, to permit the appointment of substitutes instead of the
proxies and to provide that special and extraordinary resolutions shall be taken
on a poll, to allow the issue of Bearer Shares, and to make certain other minor
amendments. Vodafone and AirTouch each agrees to use all reasonable efforts such
that, to the extent practical, the AirTouch Shareholders Meeting and the
Vodafone Shareholders Meeting shall be held as promptly as practicable after the
conditions precedent to holding such meetings have been fulfilled. Subject to
fiduciary obligations and the requirements of applicable Law and the terms of
this Agreement, including the provisions of Section 3.2. (Acquisition
Proposals), the board of directors of each of Vodafone and AirTouch shall
recommend to its respective shareholders the approval of the Merger and the
other transactions contemplated hereby and shall use best reasonable efforts to
solicit such approval.
 
    3.5.  FILINGS; OTHER ACTIONS; NOTIFICATION.
 
        3.5.1.  AirTouch and Vodafone shall each cooperate with the other and

    things, necessary, proper or advisable under this Agreement and applicable
    Laws to consummate and make effective the Merger and the other transactions

    practicable all approvals, consents, registrations, permits, authorizations
    and other confirmations required to be obtained from any third party (other
    than AirTouch Required Consents and Vodafone Required Consents) necessary,
    proper or advisable to consummate the Merger and the other transactions
    contemplated by this Agreement and (iii) use (and shall use best reasonable
    efforts to cause their respective Subsidiaries to use) their respective best
    efforts to take or cause to be taken all actions, and do or cause to be done
    all things, necessary, proper or advisable to obtain the AirTouch Required
    Consents or Vodafone Required Consents, as the case may be (including,
    without limitation, selling or otherwise disposing of or agreeing to dispose
    of or hold separate such assets, categories of assets or businesses of
    Vodafone (including Vodafone's investment in E-Plus Mobilfunk Gmbh) or
    AirTouch as necessary to obtain, such AirTouch Required Consents or Vodafone
    Required Consents; PROVIDED that neither Party shall be required by this
    Section 3.5.1.(iii) to take any action or accept or agree to any conditions,
    terms or restrictions in connection with any such AirTouch Required Consent
    or Vodafone Required Consent, as the case may be, which, individually or in
    the aggregate, would be reasonably expected to have a Material Adverse
    Effect on Vodafone or AirTouch after the Effective Time (it being understood
    that, for this purpose, materiality shall be considered with reference to
    the total equity market value of Vodafone and AirTouch). Subject to
    applicable Laws relating to the exchange of information, AirTouch and
    Vodafone shall have the right to review in advance, and to the extent
    practicable each will consult the other on, all the information relating to
    AirTouch and its Subsidiaries or Vodafone and its Subsidiaries, as the case
    may be, that appears in any filing made with, or written materials submitted
    to, any third party and/or any Governmental Entity in connection with the
    Merger and the other transactions contemplated by this Agreement. In
    exercising the foregoing right, each of AirTouch and Vodafone shall act
    reasonably and as promptly as practicable.

        3.5.2.  AirTouch and Vodafone each shall, upon request by the other,
    furnish the other with all information concerning itself, its Subsidiaries,
    directors, officers and shareholders and such other matters as may be
    reasonably necessary or advisable in connection with the Form F-4, the
    AirTouch Proxy Statement, the Vodafone Documents or any other necessary or
    appropriate filing, notice, statement, registration, submission of
    information or application made by or on behalf of AirTouch or Vodafone or
    any of their respective Subsidiaries to any third party and/or any
    Governmental Entity in connection with the Merger and the other transactions
    contemplated by this Agreement.
 
        3.5.3.  AirTouch and Vodafone each shall keep the other apprised of the
    status of matters relating to completion of the Merger and the other
    transactions contemplated by this Agreement, including promptly furnishing
    the other with copies of notices or other communications received by
    AirTouch or Vodafone, as the case may be, or any of its Subsidiaries, from
    any third party and/or any Governmental Entity with respect to the Merger
    and the other transactions contemplated by this Agreement. AirTouch and
    Vodafone each shall give prompt notice to the other of any change that
    would, individually or in the aggregate, reasonably be expected to result in

    in Article IV to the other Party's obligations to effect the Merger.
 
        3.5.4.  Prior to making any filing, notice, petition, statement,
    registration, submission of information or application to or with any third
    party and/or Governmental Entity (including any domestic or foreign national

    the other transactions contemplated by this Agreement and except as may be
    required by Law or by obligations pursuant to any listing agreement with or
    rules of any domestic or foreign national securities exchange, each Party
    shall make all reasonable efforts to consult with the other Party with
    respect to the content of such filing, notice, petition, statement,
    registration, submission of information or application and to provide the
    other Party with copies of the proposed filing, notice, petition, statement,
    registration, submission of information or application. AirTouch and
    Vodafone each shall not agree to participate in any meeting with any
    Governmental Entity in respect of any filings, investigation or other
    inquiry relating to the Merger and the other transactions contemplated by
    this Agreement unless it consults with the other Party in advance and, to
    the extent practicable and permitted by such Governmental Entity, gives the
    other Party the opportunity to attend and participate thereat.
 
        3.5.5.  In the event any claim, action, suit, investigation or other
    proceeding by any Governmental Entity or other Person or other legal or

    limitations set forth in Section 3.5.1.(iii), to defend against and respond

other transactions contemplated by this Agreement, the Parties hereby agree that
upon reasonable request to any executive officer of Vodafone or AirTouch, as the

by applicable Law, AirTouch and Vodafone each shall (and shall cause its
Subsidiaries to) afford the other's Representatives access, during normal
business hours throughout the period prior to the Effective Time, to its
properties, books, contracts and records and, during such period, each shall
(and shall cause its Subsidiaries to) furnish promptly to the other all
information concerning its business, properties and personnel as may reasonably
be requested, PROVIDED that no receipt of information pursuant to this Section
shall affect or be deemed to modify any representation or warranty made by
AirTouch or Vodafone hereunder, and PROVIDED, FURTHER, that the foregoing shall
not require AirTouch or Vodafone to permit any inquiry, or to disclose any
information, that in the reasonable judgment of AirTouch or Vodafone, as the
case may be, would (i) violate any antitrust or
 
                                      A-27
<PAGE>
competition Law or (ii) result in the disclosure of any trade secrets of third
Parties or violate any of its obligations with respect to confidentiality to
third Parties if AirTouch or Vodafone, as the case may be, shall have used
reasonable efforts to obtain the consent of such third party to such inspection
or disclosure. All such information shall be governed by the terms of the
Confidentiality Agreement, dated as of January 6, 1999, between the Parties (the
"CONFIDENTIALITY AGREEMENT"), including without limitation all such information
disclosed in the Disclosure Letters.
 
    3.7.  PUBLICITY.  The initial press release concerning this Agreement, the
Merger and the other transactions contemplated by this Agreement shall be a
joint press release, and thereafter AirTouch and Vodafone shall consult with
each other prior to issuing any press releases or otherwise making public
announcements with respect to the Merger and the other transactions contemplated

        3.8.1.  EMPLOYEE BENEFITS.
 
           3.8.1.1.  It is the specific intention that the compensation and
       benefit programs (including annual and long-term incentive programs) to
       be provided by Vodafone and its Subsidiaries for current and former
       employees and directors of AirTouch will be competitive with those
       provided generally by large industrial companies for each respective
       home-country market, both with respect to the type and variety of
       programs as well as the level of compensation and benefits afforded.
 
           3.8.1.2.  (a) Without limiting the generality of Section 3.8.1.1.,
       Vodafone shall cause the AirTouch compensation and benefit plans in
       effect on the date hereof to remain in effect for at least one year after
       the Effective Time without change to the eligibility provisions and
       levels of benefits provided thereunder.
 
           (b) Following the Effective Time, Vodafone shall, and shall cause its
       Subsidiaries to, recognize service with AirTouch and its Subsidiaries and
       any predecessor entities (and any other service credited by AirTouch
       under similar benefit plans) prior to the Effective Time for all purposes
       (including, without limitation, eligibility to participate, vesting,
       benefit accrual, eligibility to commence benefits and severance) under
       any benefit plans of Vodafone or its Subsidiaries in which the particular
       employee or former employee of AirTouch (or its respective Subsidiaries)
       participates; PROVIDED, HOWEVER, that the foregoing shall not result in
       any duplication of benefits for the same period of service. From and
       after the Effective Time, Vodafone shall, and shall cause its
       Subsidiaries to, (i) recognize any and all appropriate out-of-pocket
       expenses of each employee or former employee of AirTouch and its
       Subsidiaries for purposes of determining such employee's and former
       employee's (including their beneficiaries and dependents) deductible and
       copayment expenses and (ii) cause to be waived any provision which
       restricts benefits by reason of pre-existing conditions.
 
           3.8.1.3.  From and after the Effective Time, Vodafone shall honor,
       and shall cause its Subsidiaries to honor, in accordance with its terms,
       each existing employment, change of control, severance and termination
       agreement between AirTouch or any of its Subsidiaries, and any officer,
       director or employee of such company, including without limitation all
       legal and contractual obligations pursuant to outstanding bonus deferral
       plans, vested and accrued benefits and similar employment and benefit
       arrangements and agreements in effect as of the Effective Time.
 
           3.1.8.4.  Vodafone agrees that for three years following the
       Effective Time it shall maintain a significant business presence in the
       San Francisco Bay Area, including, but not limited to maintaining the Bay
       Area Research Tech Facility. In addition, Vodafone agrees that AirTouch's
       San Francisco office shall initially be maintained as Vodafone's
       U.S./Asia Pacific regional headquarters.

        3.8.2.  DIRECTOR AND OFFICER INDEMNIFICATION AND INSURANCE.
 
           (a) Vodafone agrees that all rights to indemnification and all
       limitations on liability existing in favor of any Indemnitee (as defined
       below) in respect of acts or omissions of such Indemnitees on or prior to
       the Effective Time as provided in the certificate of incorporation and
       by-laws of AirTouch and each of its Subsidiaries or an agreement between
       an Indemnitee and AirTouch or any of its Subsidiaries in effect as of the
       date hereof shall continue in full force and effect in accordance with
       the terms thereof.
 
           (b) For six years after the Effective Time, Vodafone shall indemnify
       and hold harmless the individuals who on or prior to the Effective Time
       were officers or directors or agents of AirTouch or any of its
       Subsidiaries (the "INDEMNITEES") to the same extent indemnification is
       provided as of the date hereof with respect to all actions or omissions
       by them in their capacities as officers or directors or agents of
       AirTouch, or taken by them at the request of, AirTouch or any of its
       Subsidiaries. In the event any claim in respect of which indemnification
       is available pursuant to the foregoing provisions is asserted or made
       within the period specified in the previous sentence, all rights to
       indemnification shall continue until such claim is disposed of or all
       judgments, orders, decrees or other rulings in connection with such claim
       are duly satisfied.

       liability insurance on terms with respect to coverage and in amounts no
       less favorable than those of such policy in effect on the date hereof;
       PROVIDED, HOWEVER, that during such period, Vodafone shall not be
       required to procure any coverage in excess of the amount that can be
       obtained for the remainder of such period for an annual premium of 150%
       of the current annual premium paid by AirTouch for its existing coverage.
 
           (d) The obligations of Vodafone under this Section 3.8.2. shall not

legends on any Vodafone ADRs (or any underlying Vodafone Ordinary Shares that

between the date hereof and the Effective Time, such Chief Executive Officers
shall jointly (i) examine various alternatives regarding the business of

with respect to regulatory authorities and bodies, in all cases subject to
applicable law. Such Chief Executive Officers shall establish committees to
assist them in various aspects of the transition planning and implementation
process including, without limitation, committees on employee transition issues,
which committees shall consist of representatives of both Vodafone and AirTouch
to be designated by their respective Chief Executive Officers.

give prompt notice to the other upon obtaining knowledge of any of the
following:
 
        3.18.1.  the occurrence or nonoccurrence of any event whose occurrence
    or nonoccurrence would be likely to cause either (i) any representation or
    warranty contained in this Agreement to be untrue or inaccurate in any
    material respect at any time from the date hereof to the Effective Time, or
    (ii) directly or indirectly, any Material Adverse Effect on such Party;

    law;
 
PROVIDED, HOWEVER, that the delivery of any notice pursuant to this Section

    (collectively, "GOVERNMENTAL CONSENTS") in connection with the consummation
    of the Merger and the other transactions contemplated hereby shall have been
    made or obtained, except where the failure to obtain such Governmental
    Consent would not, individually or in the aggregate, reasonably be expected
    to have a Material Adverse Effect on Vodafone or AirTouch after the
    Effective Time, it being understood and agreed that, for this purpose,
    materiality shall be considered with reference to the total equity market
    value of Vodafone and AirTouch and that the failure to obtain the approval
    of the FCC and, to the extent such approval is necessary, the California
    Public Utilities Commission, of the transaction contemplated by this

    restriction relating or applying to, or requiring changes in or limitations
    on, the operation of any asset or businesses of AirTouch, Vodafone or any of

    the extent not qualified by Material Adverse Effect shall be true and
    correct in each case, when made and as of the Closing Date (except that any
    representation and warranty that by its terms expressly speaks as of a
    specific date shall be true and correct as of such date) (PROVIDED that this
    clause (ii) shall be deemed satisfied so long as any failures of such
    representations and warranties to be true and correct would not,
    individually or in the aggregate, reasonably be expected to have a Material
    Adverse Effect on AirTouch), and Vodafone shall have received a certificate
    signed on behalf of AirTouch by an executive officer of AirTouch to such
    effect.

<PAGE>
        4.2.4.  TAX OPINION.  Vodafone shall have received an opinion from
    Sullivan & Cromwell, dated as of the Effective Time, substantially to the
    effect that, on the basis of the facts, representations and assumptions set
    forth in such opinion, (i) the Merger will be treated for U.S. federal
    income tax purposes as a reorganization within the meaning of Section 368(a)
    of the U.S. Code and (ii) Vodafone shall be treated as a corporation under
    Section 367(a)(1) of the U.S. Code with respect to each transfer of property
    thereto pursuant to the Merger. In rendering such opinion, counsel may
    require and rely upon representations of Vodafone and AirTouch, including
    representations and covenants substantially in the form of those contained
    in the Vodafone officer's certificates and the AirTouch officer's
    certificates attached hereto as Exhibits 3.1.5.1 and Exhibits 3.1.5.2, and,
    in addition, may rely upon an opinion of a nationally recognized investment
    bank setting forth the fair market value as of the Effective Time of the
    aggregate outstanding shares of each of the Class C Preferred Shares, Class
    D Preferred Shares and Class E Preferred Shares and the aggregate fair
    market value immediately after the Effective Time of the Vodafone Ordinary
    Shares (represented by Vodafone Depositary Shares) issued to stockholders of
    AirTouch in the Merger as compared to the aggregate fair market value
    immediately after the Effective Time of all outstanding Vodafone Ordinary
    Shares. The opinion referred to in this Section 4.2.4. shall be based upon
    the Private Letter Ruling, if obtained. The opinion set forth in clause (ii)
    above shall not address the tax consequences applicable to any stockholder
    of AirTouch who, immediately after the Merger will be a "FIVE PERCENT
    TRANSFEREE SHAREHOLDER" with respect to Vodafone within the meaning of
    United States Treasury Regulation Section 1.367(a)-3(c)(5).
 
    4.3.  CONDITIONS TO OBLIGATION OF AIRTOUCH.  The obligation of AirTouch to
effect the Merger is also subject to the satisfaction or waiver by AirTouch
prior to the Effective Time of the following conditions:
 
        4.3.1.  REPRESENTATIONS AND WARRANTIES.  The representations and
    warranties of Vodafone set forth in this Agreement (i) to the extent
    qualified by Material Adverse Effect shall be true and correct, and (ii) to
    the extent not qualified by Material Adverse Effect shall be true and
    correct, in each case, when made and as of the Closing Date (except that any
    representation and warranty that by its terms expressly speaks as of a
    specific date shall be true and correct as of such date) (PROVIDED that this
    clause (ii) shall be deemed satisfied so long as any failures of such
    representations and warranties to be true and correct, taken together, would
    not, individually or in the aggregate, reasonably be expected to have a
    Material Adverse Effect on Vodafone), and AirTouch shall have received a
    certificate signed on behalf of Vodafone by an executive officer of Vodafone
    to such effect.
 
        4.3.2.  PERFORMANCE OF OBLIGATIONS OF VODAFONE.  Vodafone shall have
    performed all material obligations required to be performed by it under this

    certificate signed on behalf of Vodafone by an executive officer of Vodafone
    to such effect.

    obtained from each Person whose consent or approval shall be required in
    order to consummate the Merger and the other transactions contemplated by
    this Agreement under any Contract to which Vodafone or AirTouch or any of
    their respective Subsidiaries is a party, except those for which the failure
    to obtain such consent or approval, individually or in the aggregate, would
    not reasonably be expected to have a Material Adverse Effect on Vodafone or
    AirTouch, as the case may be, and would not reasonably be likely to prevent
    or materially impair the ability of Vodafone or AirTouch to consummate the
    Merger and the other transactions contemplated by this Agreement.
 
        4.3.4.  TAX OPINION.  AirTouch shall have received an opinion from
    Fried, Frank, Harris, Shriver & Jacobson, dated as of the Effective Time,
    substantially to the effect that, on the basis of the facts, representations
    and assumptions set forth in such opinion, (i) the Merger will be treated
 
                                      A-34
<PAGE>
    for U.S. federal income tax purposes as a reorganization within the meaning
    of Section 368(a) of the U.S. Code and (ii) Vodafone shall be treated as a
    corporation under Section 367(a)(1) of the U.S. Code with respect to each
    transfer of property thereto pursuant to the Merger. In rendering such
    opinion, counsel may require and rely upon representations of Vodafone and
    AirTouch, including representations and covenants substantially in the form
    of those contained in the Vodafone officer's certificates and the AirTouch
    officer's certificates attached hereto as Exhibits 3.1.5.1 and Exhibits
    3.1.5.2, and, in addition, may rely upon an opinion of a nationally
    recognized investment bank setting forth the fair market value as of the
    Effective Time of the aggregate outstanding shares of each of the Class C
    Preferred Shares, Class D Preferred Shares and Class E Preferred Shares and
    the aggregate fair market value immediately after the Effective Time of the
    Vodafone Ordinary Shares (represented by Vodafone Depositary Shares) issued
    to stockholders of AirTouch in the Merger as compared to the aggregate fair
    market value immediately after the Effective Time of all outstanding
    Vodafone Ordinary Shares. The opinion referred to in this Section 4.3.4.
    shall be based upon the Private Letter Ruling, if obtained. The opinion set
    forth in clause (ii) above shall not address the tax consequences applicable
    to any stockholder of AirTouch who, immediately after the Merger, will be a
    "five-percent transferee shareholder" with respect to Vodafone within the
    meaning of United States Treasury Regulation Section 1.367(a)-3(c)(5).
 
        4.3.5.  SUPPLEMENTAL RESOLUTIONS.  The Vodafone Supplemental Resolutions
    (including the election of those New Directors designated by AirTouch, but
    excluding the resolutions relating to the Redenomination) shall have been

    Supplemental Vote.

or is not cured prior to the Termination Date; or (iv) the board of directors of
Vodafone shall have withheld the Increased Cash Consent.

Merger may be abandoned at any time prior to the Effective Time, whether before

to reconfirm such recommendation within seven business days after a written
request by Vodafone to do so; or (ii) AirTouch or its board of directors shall
recommend an Acquisition Proposal to its stockholders; or (iii) there shall be a
breach by AirTouch of any representation, warranty, covenant or agreement
contained in this Agreement which would result in a failure of a condition set
forth in paragraph 4.2.1 or 4.2.2 and cannot be or is not cured prior to the
Termination Date.
 
    5.5.  EFFECT OF TERMINATION AND ABANDONMENT.
 
        5.5.1.  In the event of termination of this Agreement and the
    abandonment of the Merger pursuant to this Article V, this Agreement (other
    than as set forth in Section 6.1. (Survival)) shall become void and of no
    effect with no liability on the part of either Party (or of any of its
    Representatives); PROVIDED, HOWEVER, that no such termination shall relieve
    either Party of any liability for damages resulting from any willful and
    intentional breach of this Agreement or from any obligation to pay, if
    applicable, the amounts payable pursuant to Section 5.5.2. or 5.5.3.
 
        5.5.2.  In the event that (i) this Agreement is terminated by either
    AirTouch or Vodafone pursuant to Section 5.2.(iii) and at the time of the
    AirTouch Shareholders Meeting (or at any adjournment thereof) an Acquisition
    Proposal exists with respect to AirTouch or (ii) this Agreement is
    terminated by Vodafone pursuant to Section 5.4.(i), 5.4.(ii) or 5.4.(iii)
    (solely with respect to a willful and intentional breach of a
    representation, warranty, covenant or agreement of AirTouch contained in
    this Agreement), then AirTouch shall promptly, but in no event later than
    two business days after the date of such termination, pay to Vodafone a
    termination payment equal to the AirTouch Termination Amount (as defined
    below), which amount shall be exclusive of any expenses to be paid pursuant
    to Section 3.9. (Expenses), payable by wire transfer of same day funds. The
    term "AirTouch Termination Amount" shall mean, in the case of termination by
    Vodafone pursuant to clause (ii) of the preceding sentence, $1,000,000,000
    (inclusive of value added tax, if any) or, in the case of termination by
    AirTouch or Vodafone pursuant to clause (i) of the preceding sentence,
    "AIRTOUCH TERMINATION AMOUNT" shall mean $225,000,000 (inclusive of value
    added tax, if any), plus, if (x) AirTouch executes and delivers an agreement
    with respect to any Acquisition Proposal (an "AIRTOUCH ALTERNATIVE
    AGREEMENT") or (y) an Acquisition Proposal with respect to AirTouch is
    consummated, in any such case, within 12 months from the date of
    termination, an additional $775,000,000 (inclusive of value added tax, if
    any) (which additional amount shall be paid promptly but in no event later
    than two business days after the earliest date on which the event requiring
    AirTouch to pay such additional sum occurs). In the event that the board of
    directors of AirTouch recommends the acceptance by AirTouch stockholders of
    a third-party tender or exchange offer for the AirTouch Common Shares, such
    recommendation shall be treated for purposes of this paragraph as though an
    AirTouch Alternative Agreement had been executed. AirTouch acknowledges that
    the agreements contained in this Section 5.5.2. are an integral part of the
    transactions contemplated by this Agreement, and that, without these
 
                                      A-36
<PAGE>
    agreements, Vodafone would not enter into this Agreement; accordingly, if
    AirTouch fails promptly to pay any amount due pursuant to this Section
    5.5.2., and, in order to obtain such payment, Vodafone commences a suit
    which results in a judgment against AirTouch for the payment set forth in
    this Section 5.5.2., AirTouch shall pay to Vodafone its costs and expenses
    (including attorneys' fees) in connection with such suit, together with
    interest on the amount due from each date for payment until the date of such
    payment at the prime rate of Citibank N.A. in effect on the date such
    payment was required to be made plus 2 percent.
 
        5.5.3.  In the event that (i) this Agreement is terminated by either
    AirTouch or Vodafone pursuant to Section 5.2.(iv), or (ii) this Agreement is
    terminated by AirTouch pursuant to Section 5.3.(i), 5.3.(ii) or 5.3.(iii)
    (solely with respect to a willful and intentional breach of a
    representation, warranty, covenant or agreement of Vodafone contained in
    this Agreement), then Vodafone shall promptly, but in no event later than
    two business days after the date of such termination, pay to AirTouch a
    termination payment equal to the Vodafone Termination Amount (as defined
    below), which amount shall be exclusive of any expenses to be paid pursuant
    to Section 3.9. (Expenses), payable by wire transfer of same day funds. The
    term "Vodafone Termination Amount" shall mean $225,000,000 (inclusive of
    value added tax, if any). Vodafone acknowledges that the agreements
    contained in this Section 5.5.3. are an integral part of the transactions
    contemplated by this Agreement, and that, without these agreements, AirTouch
    would not enter into this Agreement; accordingly, if Vodafone fails promptly
    to pay any amount due pursuant to this Section 5.5.3., and, in order to
    obtain such payment, AirTouch commences a suit which results in a judgment
    against Vodafone for the payment set forth in this Section 5.5.3., Vodafone
    shall pay to AirTouch its costs and expenses (including attorneys' fees) in
    connection with such suit, together with interest on the amount due from
    each date for payment until the date of such payment at the prime rate of
    Citibank N.A. in effect on the date such payment was required to be made
    plus 2 percent.

Board of Directors
AirTouch Communications, Inc.
One California Street, 30th Floor
San Francisco, CA 94111
 
Members of the Board:
 
    We understand that AirTouch Communications, Inc. (the "Company"), Vodafone
Group Public Limited Company ("Vodafone") and Apollo Merger Sub, Inc., a wholly
owned subsidiary of Vodafone ("Vodafone Acquisition Sub") have entered into an
Agreement and Plan of Merger, dated as of January 15, 1999 (the "Vodafone Merger
Agreement"), which provides, among other things, for the merger (the "Company
Merger") of Vodafone Acquisition Sub with and into the Company. Pursuant to the
Company Merger, the Company will become a wholly owned subsidiary of Vodafone
and each issued and outstanding share of common stock, par value $.01 per share,
of the Company (the "Company Common Stock"), other than shares owned by
Vodafone, the Company or any Subsidiary (as defined in the Vodafone Merger
Agreement) of Vodafone or the Company, will, subject to adjustment as provided
below, be converted into the right to receive (x) five (5) ordinary shares
(subject to adjustment as described below, the "Exchange Ratio"), of nominal
value 5p each, of Vodafone or, if the Redenomination (as defined in the Vodafone
Merger Agreement) is approved and becomes effective, of nominal value $.10 each
(the "Vodafone Stock") and (y) $9.00 in cash, without interest (subject to
adjustment as described below, the "Cash Consideration", together with the
Vodafone Stock to be received in the Company Merger, the "Merger
Consideration"). Notwithstanding the foregoing, pursuant to the Vodafone Merger
Agreement, in the event the 50% Test (as defined in the Vodafone Merger
Agreement) is not satisfied (A) but the Private Letter Ruling (as defined in the
Vodafone Merger Agreement) has been obtained, the Exchange Ratio shall be
reduced by the smallest fraction that legal counsel to the Company and Vodafone
agree is necessary to satisfy the 50% Test, and the Cash Consideration shall be
increased in accordance with Section 1.3.2(y)(ii) of the Vodafone Merger
Agreement or (B) and the Private Letter Ruling has not been obtained, the
Exchange Ratio shall be reduced by the smallest fraction that legal counsel to
the Company and Vodafone agree is necessary to satisfy the test set forth in
U.S. Treasury Regulation Section 1.367(a)-3(c)(3)(iii) without obtaining the
Private Letter Ruling, the Cash Consideration shall be reduced to $0, and the
Company shall, in lieu of the Cash Consideration, pay to each holder of Company
Common Stock being exchanged in the Company Merger the AirTouch Cash Payment (as
defined in the Vodafone Merger Agreement).
 
    You have asked for our opinion as to whether, as of the date hereof, the
Merger Consideration, together with the AirTouch Cash Payment, if any, is fair
from a financial point of view to holders of shares of Company Common Stock
(other than Vodafone, the Company and their respective Subsidiaries).
 
    For purposes of the opinion set forth herein, we have:
 
     (i) reviewed certain publicly available financial statements and other
         information of the Company and Vodafone;
 
                                      B-1
<PAGE>
     (ii) reviewed and discussed certain internal financial statements and other
          financial and operating data concerning the Company and Vodafone
          prepared by the respective managements of such companies;
 
    (iii) analyzed financial projections for the Company and Vodafone contained
          in certain securities analysts' research reports that were recommended
          for review by the respective managements of such companies;
 
     (iv) discussed the past and current operations and financial conditions and
          the prospects of the Company and Vodafone, including information
          relating to certain strategic, financial and operational benefits
          anticipated from the Company Merger, with the respective managements
          of such companies;
 
     (v) analyzed the estimated pro forma impact of the Company Merger on
         Vodafone's earnings per share, cash flow, consolidated capitalization
         and financial ratios;
 
     (vi) reviewed the reported prices and trading activity for the Company
          Common Stock and the Vodafone Stock and Vodafone ADRs (as defined in
          the Vodafone Merger Agreement);
 
    (vii) reviewed and discussed with senior executives of each of the Company
          and Vodafone the strategic rationale for, and certain regulatory
          issues associated with, the Company Merger;
 
   (viii) compared the financial performance of the Company and Vodafone and the
          prices and trading activity of the Company Common Stock and the
          Vodafone Stock and Vodafone ADRs with that of certain other comparable
          publicly traded companies and their securities;
 
     (ix) reviewed the financial terms, to the extent publicly available, of
          certain comparable transactions;
 
     (x) participated in discussions and negotiations among representatives of
         the Company and Vodafone and their respective financial, accounting and
         legal advisors;
 
     (xi) reviewed the Vodafone Merger Agreement and certain related documents;
          and
 
    (xii) performed such other analyses and considered such other factors as we
          have deemed appropriate.
 
    We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the internal financial statements and other
financial and operating data and discussions relating to the strategic,
financial and operational benefits anticipated from the Company Merger, we have
assumed that such financial statements and other financial and operating data
have been reasonably prepared on bases reflecting the best currently available
estimates and good faith judgments of the future competitive, operating and
regulatory environments and related financial performance of the Company and
Vodafone. In relying on the financial projections for Vodafone included in the
securities analysts' research reports reviewed by us, we have assumed that the
recommendation of these reports to us by management of Vodafone indicated their
belief that these reports were reasonably prepared on the bases set forth in the
prior sentence. We have relied on the financial projections for AirTouch
included in the securities analysts' research reports reviewed by us based on
our own independent evaluation of these reports and indications by management of
AirTouch that the analyses contained in these reports were reasonably
comprehensive and detailed and were based on assumptions about the trends
influencing AirTouch's financial results that were generally consistent with
those of AirTouch's management. We have not made any independent valuation or
appraisal of the assets or liabilities of the Company or Vodafone, nor have we
been furnished with any such appraisals. Our opinion is necessarily based on
economic, market and other conditions as in effect on, and the information made
available to us as of, the date hereof.
 
                                      B-2
<PAGE>
    We have further assumed, with your consent, that the Company Merger will be
consummated in accordance with the terms set forth in the Vodafone Merger
Agreement (without waiver of any condition contained therein) and the Company
Merger will be treated as a tax-free reorganization and/or exchange, each
pursuant to the Internal Revenue Code of 1986. In addition, we have assumed that
obtaining all necessary regulatory approvals for the Company Merger will not
have an adverse effect on the Company, Vodafone or the contemplated benefits
expected to be derived in the Company Merger.
 
    In arriving at our opinion, we were not authorized to solicit, and did not
solicit, interest from any party with respect to the acquisition of the Company
or any of its assets, although we participated in discussions with Vodafone and
Bell Atlantic Corporation.
 
    We have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for the Company and Bell Atlantic
Corporation and have received fees for the rendering of these services.
 
    It is understood that this letter is for the information of the Board of
Directors of the Company and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by the Company in respect of the Company Merger with the
Securities and Exchange Commission. In addition, this opinion does not in any
manner address the prices at which the Vodafone Stock will trade following
announcement or consummation of the Company Merger, and Morgan Stanley expresses
no opinion or recommendation as to how the holders of the Company Common Stock
should vote at the stockholders' meetings held in connection with the Company
Merger.
 
    Based on and subject to the foregoing, we are of the opinion on the date
hereof that the Merger Consideration, together with the AirTouch Cash Payment,
if any, is fair from a financial point of view to the holders of shares of
Company Common Stock (other than Vodafone, the Company and their respective
Subsidiaries).

Attn: Chris Gent
 
Ladies and Gentlemen,
 
You have requested our opinion as to the fairness from a financial point of view
to Vodafone Group Plc (the "Company") of the Consideration (as defined below) to
be paid by the Company for each outstanding share of common stock, par value
$0.01 per share ("AirTouch Shares"), of AirTouch Communications, Inc.
("AirTouch") pursuant to an Agreement and Plan of Merger dated as of January 15,
1999 (the "Merger Agreement") among the Company, AirTouch and Apollo Merger Sub,
Inc., a wholly owned subsidiary of the Company. The "Consideration" consists of
(i) five (5) ordinary shares, nominal value 5 pence per share ("Company Shares")
of the Company, and (ii) $9.00 in cash, for each AirTouch Share, subject to
rebalancing in the circumstances described in Section 1.3 of the Merger
Agreement.

In connection with this opinion, we have reviewed, among other things:
 
 (i) the Merger Agreement,
 
 (ii) certain publicly available information, including the audited financial
      statements of the Company for the five years ended March 31, 1998, the
      audited financial statements of AirTouch on Form 10-K for the five years
      ended December 31, 1997, the unaudited pro forma financial statements of
      AirTouch for the year ended December 31, 1997, adjusted to reflect the
      acquisition of the U.S. wireless business of U S WEST, the unaudited
      interim reports of the Company for the periods ended September 30, 1997
      and 1998, the unaudited quarterly reports of AirTouch on Form 10-Q for the
      three consecutive quarterly periods ended September 30, 1997 and 1998, and
      certain other communications from the Company and AirTouch to their
      respective shareholders; and
 
(iii) certain internal financial analyses and forecasts for the Company and
      AirTouch prepared by the management of the Company, including an estimate
      of expected cost savings and other synergies.
 
We have also participated in discussions with members of the senior management
of the Company regarding the strategic rationale for, and the potential benefits
of, the transaction contemplated by the Merger Agreement and the past and
current business operations, financial condition and future prospects of the
Company and AirTouch. In addition, we have (i) reviewed the reported price and
trading activity for Company Shares and AirTouch Shares, (ii) compared certain
financial and stock market information for the Company and AirTouch with similar
information for certain other companies, the securities of which are publicly
traded, (iii) reviewed the financial terms of certain business combinations in
the telecommunications industry specifically and in other industries generally
and (iv) performed such other studies and analyses as we considered appropriate.
 
We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us and have assumed such accuracy and completeness
for purposes of rendering this opinion. We have assumed that the financial
analyses and forecasts provided to us by the Company were reasonably prepared
based on assumptions reflecting the best currently available estimates and
judgments by the management of the Company as to the expected future results of
operations and financial condition of the Company and AirTouch. In addition, we
have not made an independent evaluation or appraisal of the assets and
liabilities of the Company or AirTouch or any of their respective subsidiaries,
and we have not been furnished with any such valuation or appraisal.
 
Our advisory services and the opinion expressed herein are provided for the
information and assistance of the Board of Directors of the Company in
connection with its consideration of the transaction contemplated by the Merger
Agreement, and such opinion does not constitute a recommendation as to how any
holder of Company Shares should vote with respect to such transaction.
 
Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that, as of the date hereof, the
Consideration to be paid by the Company for each AirTouch Share pursuant to the
Merger Agreement is fair from a financial point of view to the Company.
 
Very truly yours,
 
GOLDMAN SACHS INTERNATIONAL

Preferred Stock shall surrender the certificates evidencing such shares to the
Corporation at the place designated in a notice of redemption provided by the
Corporation to the holders of record of shares of Class D Preferred Stock and
shall there upon be entitled to receive any funds payable pursuant to this

affiliate of a bank or trust company, having an office or agency in New York
City and having a capital and surplus of at least $50,000,000, an amount of
funds required to be delivered by the Corporation pursuant to this Section 4
upon the occurrence of the related redemption. Any interest accrued on such
funds shall be paid to the Corporation from time to time. Any funds so deposited

D Preferred Stock so called for redemption shall look only to the Corporation
for delivery of such funds.

Stock, Series 1998, par value $0.01 per share, (the "Class E Certificate of

capital stock of the Corporation entitled to vote with the Common Stock (the

coming before any meeting of the stockholders on which the holders of Common
Stock and Voting Stock are entitled to vote, on the basis of twelve (12) votes
for each share of Class E Preferred Stock held. The holders of the Class E
Preferred Stock, Voting Stock and Common Stock shall vote together as one class
except as otherwise set forth herein or as otherwise provided by law or

Incorporation of the Corporation, whether by merger, consolidation or otherwise,
to change the Maturity Date or any Dividend Payment Date or to decrease the
amount of any dividend or redemption payment or any liquidation preference of
the Class E Preferred Stock."
 
    10.  The first sentence of paragraph (a) of Section 3 of Schedule A to the
Class E Certificate of Designation shall be amended by adding the following
proviso at the very end thereof:
 
    "provided, however, that with respect to the first Dividend Payment Date
following the effective time of the merger of AirTouch Merger Sub, Inc. with and

3. INFORMATION ON VODAFONE
 
    Vodafone is a leading international provider of mobile telecommunications
services. It owns interests in mobile operations in the United Kingdom and 12
other countries which, as at 31 March 1999, served over 10.4 million
proportionate customers, of which over 9.5 million are connected to digital
networks. Vodafone was formed in 1984 as a subsidiary of Racal Electronics Plc
("Racal"). Approximately 20 per cent of Vodafone, then known as Racal Telecom
Limited, was offered to the public in October 1988. Vodafone was fully demerged
from Racal and became an independent company in September 1991.
 
    Vodafone's principal business consists of the operation in the United
Kingdom of digital and analogue cellular radio telephone and paging networks.
Vodafone was the first cellular operator in the United Kingdom to open its
network for service. After commencing service on its analogue network on 1
January 1985, it subsequently launched one of the world's first digital networks
in July 1992. It has been the UK market leader since 1986 and is presently the
largest of the four United Kingdom operators with more than 5.5 million
customers at 31 March 1999, of which over 1.8 million are on its innovative "Pay
As You Talk" prepaid service.
 
    Outside the United Kingdom, Vodafone currently has interests including, in
most cases, board representation and significant operating influence in cellular
operators in Australia, Egypt, Fiji, France, Germany, Greece, Malta, the
Netherlands, New Zealand, South Africa, Sweden and Uganda. These cellular
interests are licensed to serve over 360 million people. As at 31 March 1999,
Vodafone's international proportionate customer base outside the UK was almost
4.9 million. Vodafone also holds an approximate 3 per cent interest in
Globalstar, L.P. ("Globalstar"), which is constructing and will operate a 48
satellite low-earth wireless communications system. Vodafone is licensed to be
the Globalstar exclusive service provider in Australia, Greece, Lesotho, Malta,
South Africa, Swaziland and the United Kingdom.
 
    Over the three financial years ended 31 March 1999, Vodafone continued to
make significant investments in its core activities. The principal investments
Vodafone has made are as follows:
 
    3.1 In the year ended 31 March 1999, Vodafone acquired 100 per cent of New
Zealand's only GSM network operator which has been rebranded as Vodafone. The
total consideration payable by Vodafone in respect of this acquisition was L235
million.
 
    3.2 In the year ended 31 March 1998, Vodafone acquired controlling interests
in C.V. Gemeenschapplijk Bezit Libertel, the holding partnership of Libertel
B.V., the Dutch cellular network operator, and its principal service provider,
Libertel Verkoop en Services B.V. (formerly Liberfone B.V.), by increasing its
interest from 35 per cent to 70 per cent for a net cash consideration of L256
million and the assumption of L120 million of long term debt.
 
                                      E-2
<PAGE>
    3.3 In December 1997, Vodafone exercised an option to increase its
shareholding in Societe Francaise du Radiotelephone S.A. from 16.11 per cent to
20 per cent for an aggregate consideration of L134 million. Societe Francaise du
Radiotelephone S.A. has been accounted for as an associated company since that
date.
 
    3.4 In the year ended 31 March 1997, Vodafone acquired controlling interests
in the Greek cellular network operator, Panafon S.A., and its principal service
provider, Panavox S.A., taking Vodafone's interest from 45 per cent to 55 per
cent. The consideration paid for this transaction was L66 million. In addition,
in the 1997 fiscal year Vodafone acquired controlling interests in three U.K.
service providers for an aggregate consideration of L147 million.
 
4. INFORMATION ON AIRTOUCH
 
    AirTouch is a leading international mobile telecommunications company, with
a significant presence in the U.S., Europe and Asia. As at 31 March 1999,
AirTouch had over 18.8 million customers based on its ownership share of the
cellular, paging and personal communications service ("PCS") ventures in which
it has an interest. At that date, those ventures were licensed to serve an
estimated 723 million people.
 
4.1 U.S. CELLULAR AND PCS OPERATIONS
 
    AirTouch is one of the largest providers of mobile telecommunications
services in the United States. In the U.S., AirTouch's cellular and PCS ventures
had over 10.3 million customers at 31 March 1999, of which AirTouch's
proportionate share was approximately 8.7 million customers. AirTouch's
interests in its U.S. cellular and PCS ventures at 31 March 1999 represented
over 95 million POPs, a number reflecting the population of a market multiplied
by AirTouch's ownership interest in a licensee operating in the market. AirTouch
controls or shares control over cellular systems in 15 of the 30 largest
cellular markets in the U.S., including Los Angeles, Detroit, San Francisco,
Atlanta, San Diego, Minneapolis, Phoenix, Seattle, Denver, Cleveland, Portland,
San Jose, Kansas City, Cincinnati and Sacramento. In addition, through PrimeCo
Personal Communications, L.P. ("PrimeCo"), AirTouch shares control over PCS
systems operations in over 30 other major U.S. cities, including Chicago,
Dallas, Tampa, Houston, Miami, New Orleans and Milwaukee.
 
    AirTouch's U.S. PCS operations are carried out jointly within its PrimeCo
partnership with Bell Atlantic Mobile. AirTouch and Bell Atlantic Mobile are
equal partners in PrimeCo, whose markets complement the existing U.S. cellular
franchises of the partners. PrimeCo began providing service in November 1996 and
at 31 December 1998 had over 902,000 customers. Bell Atlantic stated in a proxy
statement dated 13 April 1999 that, upon completion of the Merger between
AirTouch and Vodafone, Bell Atlantic intends to exercise its option to dissolve
PrimeCo and divide PrimeCo's personal communications services properties with
AirTouch in accordance with procedures contained in the PrimeCo partnership
agreement. The Directors of Vodafone and AirTouch consider that, if such a
dissolution were to take place, it would not have a material adverse effect on
the combined Vodafone AirTouch Group.
 
4.2 INTERNATIONAL CELLULAR OPERATIONS
 
    Outside the U.S., as at 31 March 1999, AirTouch's cellular ventures were
licensed to serve more than 570 million people and had over 29 million
customers, of which AirTouch's proportionate share was approximately 6.6
million. AirTouch holds significant ownership interests, with board
representation and significant operating influence, in cellular systems
operating in Belgium, Egypt, Germany, India, Italy, Japan, Poland, Portugal,
Romania, South Korea, Spain and Sweden.
 
                                      E-3
<PAGE>
4.3 US PAGING
 
    Industry surveys indicate that AirTouch is also among the largest providers
of paging services in the U.S., with approximately 3.5 million units in service
as at 31 March 1999.
 
4.4 GLOBALSTAR
 
    AirTouch holds a 5.2 per cent interest in Globalstar and is licensed to be
the exclusive Globalstar service provider in the United States, the Caribbean
and eastern Asia (Indonesia, Japan, Malaysia) and, through partnerships, in
Canada and Mexico.
 
4.5 RECENT ACQUISITIONS AND MERGERS
 
    In April 1998, AirTouch completed the acquisition of the US cellular
business and the 25 per cent PrimeCo interest of MediaOne Group, Inc. (the
"MediaOne Group Merger"). AirTouch issued approximately 59.4 million shares of
AirTouch common stock ("AirTouch Common Shares") having a fair market value of
$2.9 billion on the date of issuance, approximately $1.6 billion of dividend
bearing preferred stock with a 5.143 per cent coupon, assumed approximately $1.4
billion of debt associated with the acquired businesses, and granted MediaOne
Group registration rights with respect to the AirTouch Common Shares and
preferred stock issued. No cash was acquired or paid in the MediaOne Group
Merger.
 
    In August 1996, AirTouch acquired approximately 63 per cent of the
outstanding stock of Cellular Communications, Inc. that it did not already own
for approximately $1.6 billion. The consideration consisted of $1.04 billion in
AirTouch preferred securities, $393 million in cash, AirTouch stock options
valued at approximately $17 million and the assumption of $217 million of zero
coupon convertible subordinated notes due 1999, all of which have been redeemed.
 
5. PROPOSED MERGER WITH AIRTOUCH
 
    Vodafone and AirTouch have entered into an Agreement and Plan of Merger,
dated as of 15 January 1999 (the "Merger Agreement"), together with Apollo
Merger Sub, Inc. (a wholly owned subsidiary of Vodafone) ("Merger Sub") pursuant
to which they agreed that Merger Sub would be merged with and into AirTouch.
AirTouch will become a subsidiary of Vodafone in accordance with the terms in
the Merger Agreement (the "Merger") and Vodafone will be renamed "Vodafone
AirTouch Public Limited Company" ("Vodafone AirTouch") from the Effective Date.
 
    In addition, prior to the Merger becoming effective, an internal
reorganisation of AirTouch will be undertaken by AirTouch, the effect of which
will be to amend AirTouch's certificate of incorporation to satisfy requirements
for the Merger to be tax free to U.S. holders of AirTouch Common Shares, except
with respect to cash received in the Merger.
 
    Vodafone AirTouch's shares will remain listed on the London Stock Exchange
and its ADSs will remain listed on the New York Stock Exchange. Following the
Effective Date, Vodafone AirTouch will own all of the outstanding common stock
of AirTouch, although certain outstanding preferred shares of AirTouch will
continue to be held by their existing holders. As a result, Vodafone AirTouch is
expected to control, through its ownership of all of the AirTouch Common Shares,
between approximately 94.4 per cent and 96.9 per cent of the voting rights in
AirTouch, depending on the number of AirTouch preferred shares converted into
AirTouch Common Shares and the number of AirTouch stock options exercised prior
to the Merger becoming effective.
 
    Under the terms of the Merger, AirTouch Common Shareholders (other than
Vodafone, AirTouch, their respective subsidiaries and AirTouch Common
Shareholders who properly exercise statutory rights of appraisal) will be
entitled to receive for each AirTouch Common Share five Vodafone AirTouch
 
                                      E-4
<PAGE>
ordinary shares ("Vodafone AirTouch Ordinary Shares") in the form of Vodafone
AirTouch ADSs plus $9.00 in cash (the "Cash Consideration"), without interest.
 
    Each Vodafone AirTouch ADS will represent ten Vodafone AirTouch Ordinary
Shares and, as a consequence, AirTouch Common Shareholders will receive 0.5 of a
Vodafone AirTouch ADS in exchange for each AirTouch Common Share they own at the
Effective Date. AirTouch Common Shareholders who would otherwise have been
entitled to receive a fraction of a Vodafone AirTouch ADS will be entitled to
receive, in lieu thereof, a payment in cash (without interest) equal to their
proportionate interest in the net proceeds from the sale on the New York Stock
Exchange of Vodafone AirTouch ADSs representing the aggregate of all fractional
entitlements.
 
    Upon the Merger becoming effective, all employee options to acquire AirTouch
Common Shares outstanding at that time will convert into options to acquire
Vodafone AirTouch Ordinary Shares (in the form of Vodafone AirTouch ADSs) after
adjustment to take account of the exchange ratio and the Cash Consideration.
There is a maximum number of 33.4 million AirTouch employee options outstanding
as at 20 April 1999 (the latest practicable date prior to the date of this
document). It is expected that up to 9.9 million may have vested and been
exercised by the Effective Date and that the balance of approximately 23.5
million will become exercisable immediately after the Effective Date.
 
    The Merger is subject to the approval of the shareholders of Vodafone and
AirTouch at general meetings of the respective companies, together with the
fulfillment of certain other conditions, including obtaining regulatory
consents.
 
    The Merger Agreement may be terminated by mutual consent of the parties or
by either party in certain circumstances before the Merger becomes effective and
in certain circumstances a termination payment of either $1 billion (L620
million) or $225 million (L140 million) may be payable by AirTouch to Vodafone
or $225 million (L140 million) by Vodafone to AirTouch pursuant to the Merger
Agreement.
 
    The Merger will become effective only following the receipt of shareholder
approvals and the satisfaction of the other conditions to the Merger. Vodafone
and AirTouch hope to complete the Merger in June or July of 1999.
 
6. REDENOMINATION, DIVIDENDS AND ACCOUNTING
 
    It is proposed to redenominate the existing Vodafone ordinary shares of 5p
each into ordinary shares of $0.10 each immediately prior to the Merger taking
effect (the "Redenomination"). The Merger is not conditional upon the
Redenomination becoming effective. However, as the Redenomination is being
proposed in connection with the Merger, subject to the High Court's
confirmation, the board will not implement the Redenomination unless and until
all the conditions to the Merger are, or are believed by the board, likely to be
satisfied or waived in all respects.
 
    Under English law, a public company is required to have an issued share
capital with a sterling nominal value of at least L50,000. Therefore, upon the
Redenomination taking place, the Company will issue L50,000 fixed rate shares at
par to one of the Company's bankers so that the Company complies with this
requirement. The Company expects to undertake to the holder of the fixed rate
shares that it will seek shareholder consent to enter into a contract for the
repurchase of the shares at the annual general meeting in 2003.
 
    Holders of Vodafone AirTouch Ordinary Shares will be paid dividends in
sterling and holders of Vodafone AirTouch ADSs will receive from the Depositary
a payment in U.S. dollars equivalent to that paid in sterling on the underlying
Vodafone AirTouch Ordinary Shares. It is expected that half-yearly dividends
will be paid on Vodafone AirTouch Ordinary Shares in February and August.
 
                                      E-5
<PAGE>
    Vodafone AirTouch will account for the Merger using the acquisition method
of accounting under U.K. GAAP. This will result in a goodwill amortisation
charge of approximately L2 billion per annum for a number of years after the
Merger, thereby reducing the reported consolidated profit of the Company. This
goodwill amortisation arises as an accounting charge against profit upon
consolidation of Vodafone and AirTouch and will not affect Vodafone AirTouch's
cash flows, distributable reserves or ability to pay dividends. Following the
Merger, Vodafone AirTouch will report earnings per share before goodwill
amortisation expense and profit or loss on the disposal of fixed asset
investments, in addition to basic and diluted earnings per share. Pro forma
earnings per share for the year ended 31 March 1998 and six months ended 30
September 1998 on the adjusted basis were 10.65p and 8.44p respectively, as
described further in Section A of Part IV of the Listing Particulars.
 
    The financial year of Vodafone AirTouch will end on 31 March in each year.
The financial statements of Vodafone AirTouch will be published in sterling and
will be prepared in accordance with U.K. GAAP. Vodafone AirTouch financial
statements will also include a summary of the effects of the differences between
U.K. GAAP and U.S. GAAP for certain financial information such as net income,
shareholders' equity and total assets. Vodafone AirTouch will initially report
results half-yearly and will move to a quarterly basis within two years from the
Effective Date.
 
7.  FINANCING THE MERGER
 
    Vodafone expects to pay approximately $5.5 billion (L3.4 billion) in cash to
AirTouch Common Shareholders in the Merger depending on the number of AirTouch
Common Shares in issue at the time of the Merger and assuming no exercise of
appraisal rights, reflecting a cash consideration of $9 per AirTouch Common
Share. In addition, Vodafone currently expects that the expenses of Vodafone and
AirTouch in connection with the Merger will be approximately $270 million (L167
million).
 
    The aggregate value of the share consideration to be paid by Vodafone
pursuant to the Merger, calculated on the basis of the per share price of
1,066p, being the closing middle market quotation for Vodafone ordinary shares
as derived from the Daily Official List of the London Stock Exchange on 20 April
1999 (the latest practicable date prior to the posting of the document)
multiplied by 3,075,000,000 (being the maximum number of consideration shares
expected to be issued), is approximately L32.8 billion ($52.9 billion) after
applying an exchange rate of $1.6135: L1 (being the noon-buying rate prevailing
at 20 April 1999) and assuming that no appraisal rights are exercised. The
aggregate value of the Cash Consideration to be paid by Vodafone pursuant to
this Merger, calculated on the basis of $9 per AirTouch Common Share is
approximately $5.5 billion (L3.4 billion), on the basis that 615,000,000
AirTouch Common Shares are outstanding at the Effective Date and assuming that
no appraisal rights are exercised.
 
    Vodafone and AirTouch entered into a $10.5 billion (L6.5 billion) facility
agreement on 16 April 1999 to finance the aggregate Cash Consideration, to pay
for the expenses of the Merger and for other general corporate purposes. Part of
this facility comprises 364 day tranches, with options for Vodafone to extend by
an additional one year, and part of it is revolving for up to five years.
 
    Due to the additional indebtedness that Vodafone will incur to finance the
Cash Consideration and to pay expenses associated with the Merger, as well as
the rating differential of the existing indebtedness of the two companies,
Standard & Poor's and Moody's Investor Services may downgrade Vodafone's
corporate credit debt ratings. However, Vodafone and AirTouch believe that any
consequential increase in the net borrowing costs of Vodafone AirTouch after the
Merger would not be material.
 
8.  RISK FACTORS RELATING TO THE MERGER
 
    Vodafone and AirTouch entered into the Merger Agreement with the expectation
that the Merger would result in certain cost savings and revenue enhancements.
There can be no assurance that the
 
                                      E-6
<PAGE>
Vodafone AirTouch Group will realise any of the anticipated benefits in full or
at all. Vodafone and AirTouch must obtain, as a condition to their obligation to
complete the Merger, clearance under EU competition laws and the approval of the
Federal Communications Commission. In addition, both companies operate in highly
competitive and regulated telecommunications markets and the licensing,
construction and operation of telecommunications systems and services and the
allocation of frequency spectrum are subject to extensive regulation and
supervision by various government entities.
 
    The Year 2000 problem could result in system failure or miscalculations
causing disruptions of operations. Both Vodafone and AirTouch have implemented
programmes which seek to ensure that they do not suffer business losses from
failures due to the Year 2000 problem. They are taking positive steps to
minimize the effect of the Year 2000 date change before, after and during the
Year 2000 on their ability to maintain their networks and to continue to provide
services to their customers.
 
    Vodafone's planned remediation and millennium testing activities were
successfully completed for all essential systems by the target date of 31
December 1998 and roll-out of these systems is already largely complete with a
target end date in the second quarter of 1999. Activities outstanding include
transition and contingency planning, business scenario testing and completing
millennium activities for all non-critical systems.
 
    Based on the current progress of AirTouch's Year 2000 efforts and on the
assumption that third parties will meet their commitments, AirTouch believes
that it can prevent serious disruption to the mission-critical systems of its
consolidated markets.
 
9. PROPOSED DIRECTORS' SERVICE ARRANGEMENTS
 
9.1 VODAFONE DIRECTOR'S SERVICE CONTRACTS
 
    All four executive directors, Chris Gent, Peter Bamford, Julian Horn-Smith
and Ken Hydon, have service contracts with Vodafone which can be terminated on
giving 12 months' notice. Vodafone has the right to pay an executive director in
lieu of giving him notice. All the executive directors' service contracts expire
automatically on the birthday of the executive that represents his normal
retirement age which is currently 60 years.
 
    The executive directors receive additional protection if Vodafone terminates
or gives notice to terminate their employment within 12 months of a change of
control of Vodafone. In such circumstances, Vodafone must give the executive
director 24 months' notice. Provided certain conditions are fulfilled, each
executive director may also be entitled to payment of the equivalent of two
years' salary and benefits. Payment of the sum described is conditional on the
executive director signing an agreement or agreements accepting it in full and
final settlement of all claims against the Vodafone Group arising out of the
termination of his employment and undertaking to remain bound by confidentiality
obligations and restrictions on his activities after termination.
 
    The executive directors current salaries are Chris Gent L648,000, Peter
Bamford L333,900, Julian Horn-Smith L361,800, and Ken Hydon L344,500. The
executive directors are contributing members of the Vodafone Group Directors
Pension Scheme and Peter Bamford also participates in the Vodafone Group funded
and approved retirement benefits scheme in order to conform his benefits to
those of the other Executive Directors. Each executive director is also provided
with a company car, company sick pay, premiums paid by Vodafone for a private
health insurance scheme for himself, his wife and his children under 21. The
executive directors participate in Vodafone's executive share schemes, the
Vodafone Group Short Term Incentive Plan and the Vodafone Group Long Term
Incentive Plan and are entitled to participate in its all-employee share
schemes, the savings related share option scheme and the profit sharing scheme.
 
                                      E-7
<PAGE>
    On condition that the Merger becomes effective, Chris Gent's salary will
increase to L900,000, Peter Bamford's to L490,000, Julian Horn-Smith's to
L490,000 and Ken Hydon's to L490,000. Conditional on the Merger becoming
effective each of Chris Gent, Julian Horn-Smith and Ken Hydon will receive a
Merger bonus of L325,000, L150,000 and L175,000 respectively. The existing
Vodafone executive directors and Lord MacLaurin will each receive 5 per cent
increases in their fees with effect from the earlier of 1 July or the Effective
Date. Non-executive directors may elect to receive their fees in shares.
 
    The appointment of Lord MacLaurin, Vodafone's Chairman, is subject to the
terms of an agreement with Vodafone dated 21 July 1998. Lord MacLaurin is
appointed as a non-executive director for a three year term provided that he
does not resign from the board or, having retired by rotation, he is re-elected
to the board. His appointment may be terminated early if Lord MacLaurin has
prolonged absence for ill-health. He is provided with a car to assist in the
performance of his duties.
 
9.2 PROPOSED DIRECTORS' SERVICE CONTRACTS
 
    Arun Sarin and Mohan Gyani are each employed by AirTouch under employment
agreements dated 12 February 1998. From the Effective Date they will continue to
be employed under those agreements. Messrs Sarin and Gyani's salary are $750,000
and $422,000 per annum with effective from 1 April 1999.
 
    Messrs Sarin and Gyani's employment can be terminated by either party by 30
days' prior written notice to the other. However, the service contracts can only
be terminated by one year's prior written notice. Following a change in control
the first effective date of termination of the service contracts can be no
earlier than 3 years after that change in control.
 
    On termination following a change in control, Messrs Sarin and Gyani are
entitled to a cash payment of three time base compensation, plus 300 per cent of
the target award (currently 90 percent and 65 percent of salary respectively)
under the AirTouch Communications Incentive Plan. All equity incentive awards
will become fully exercisable and they would be entitled to other benefits such
as continued welfare benefits for a three year period. If these payments are
subject to excise tax, AirTouch is also required to pay an additional gross-up
payment so that the employee receives the net amount he would have received had
such tax not applied.
 
    On termination of the employee's employment where there is no change of
control, the cash payment is reduced to one and one half times base
compensation, plus 150 per cent of the target award and the period which welfare
and other benefits are continued is also reduced. The payments are also
conditional on the employee signing a release of all claims against AirTouch in
connection with the employment or its termination.
 
    If any payment made to the employee under the employment agreements would be
subject to excise tax the employee is entitled to additional payments equal to
the excise tax payable on the total payment. Messrs Sarin and Gyani are also
eligible to participate in employee benefit plans and executive compensation
programmes maintained by AirTouch and will participate in the New Vodafone
AirTouch Share Schemes. As part of the Merger Agreement, Vodafone has undertaken

    At close of business on 31 March 1999 Vodafone Group had given guarantees
and indemnities to third parties of L174.7 million. At close of business on 31
March 1999 AirTouch Group had given guarantees and indemnities to third parties

    Save as disclosed above and in respect of the litigation disclosed in
Section 14 below, the effect of which is not as yet quantifiable, and apart from
their respective intra-group liabilities, neither the Vodafone Group nor the
AirTouch Group had outstanding as at 31 March 1999 any loan capital issues, or
created but unissued, term loans, other borrowings or indebtedness in the nature
of borrowing, including bank overdrafts, liabilities under acceptances (other
than normal trade bills) or acceptance credits, hire purchase commitments, or
obligations under finance leases, mortgages, charges, guarantees or other
material contingent liabilities.
 
    In addition, as at 31 March 1999 the Vodafone Group had cash of L6.1 million
and the AirTouch Group had cash of L3.6 million.
 
    Foreign currency amounts have been translated into sterling at the exchange
rates at close of business on 31 March 1999.
 
11. WORKING CAPITAL
 
    Vodafone is of the opinion that, taking into account available bank and
other money market facilities, Vodafone, as enlarged by the Merger with
AirTouch, has sufficient working capital for at least the next twelve months
from the date of the Listing Particulars.
 
12. FINANCIAL AND TRADING POSITION
 
    Since 30 September 1998, being the date to which the most recent unaudited
interim financial statements have been published, and save as disclosed in
Section 8 of Part I (Current Trading and Prospects) and Section B of Part IV
(Indebtedness of the Vodafone Group and the AirTouch Group) of the Listing
Particulars, there has been no significant change in the financial or trading
position of the Vodafone Group.
 
    Since 31 March 1999, being the date to which the most recent unaudited

13. MATERIAL CONTRACTS
 
    13.1 Except as disclosed in Section 13.2 below and for the Merger Agreement,
no contracts other than contracts entered into in the ordinary course of
business, have been entered into by Vodafone or any of its subsidiaries within
the two years immediately preceding the date of this document which are, or may
be, material.
 
    13.2 Vodafone and AirTouch have entered into a $10,500,000,000 term and
revolving credit facility dated 16 April 1999 (the "Facility"), provided by the
lenders.
 
    The Facility is split into three tranches. Tranche A is a $4,000,000,000
revolving loan facility and Tranche B a $3,000,000,000 term loan facility, each
of which is available in the first year of the Facility. Vodafone has the option
of extending the repayment of advances under those tranches up to the second
anniversary of the date of the Facility. Tranche C is a $3,500,000,000 revolving
loan facility, available for five years. Advances may be drawn in US dollars,
sterling and euros.
 
    Facility advances will bear interest at a rate per annum equal to the
aggregate of (i) the applicable margin, (ii) the London interbank offered rate
and (iii) the cost to the lenders of complying with capital adequacy and other
regulatory requirements which are passed on to the borrowers. The applicable
margin varies for each of the tranches and according to tranche utilization and
the credit rating assigned to Vodafone AirTouch at the relevent time, in a range
from 0.45 per cent per annum to 0.80 per cent per annum. Commitment fees are
also payable on undrawn amounts of the Facility at 0.125 per cent per annum on
Tranches A and B, and 40 per cent of the margin on Tranche C.
 
    If there is a change in control of Vodafone, individual lenders may require
that their participation in the Facility be cancelled and prepaid if they are
not able to agree terms on which they are willing to continue to participate in
the Faciltiy.
 
    Certain other terms and conditions usual for facilities of this type apply
to the Facility (including conditions precedent, prepayment provisions,
representations and warranties, covenants (including financial ratios), events
of default, indemnities and provisions to protect the margin receivable by the
lenders). Vodafone has the option, at its election, to suspend the operation of
certain specified conditions to the availability of the Facility for up to two
months before completion of the Merger to provide certainty of funding.
 
    13.3 Except as disclosed in Section 13.2 above, Section 13.4 below and for
the Merger Agreement, no contracts, other than contracts entered into in the
ordinary course of business, have been entered into by members of the AirTouch
Group within the two years immediately preceding the date of this document which
are, or may be, material.
 
    13.4 AirTouch entered into an agreement and plan of merger dated 29 January
1998 which was completed in April 1998 (the "MediaOne Agreement") between U S
WEST, Inc., now MediaOne Group, Inc., ("MediaOne"), U S WEST Media Group, Inc.,
U S WEST NewVector, Inc. ("NV"), U S WEST PCS Holdings, Inc. ("PCS Holdings")
and AirTouch.
 
    Under the MediaOne Agreement, AirTouch acquired the US cellular business of
MediaOne and MediaOne's 25 per cent interest in PrimeCo in consideration of
which AirTouch issued approximately 59.4 million AirTouch Common Shares having a
fair market value of $2.9 billion on the date of issuance and approximately $1.6
billion of dividend-bearing redeemable preferred stock with a 5.143 per cent
coupon and granted MediaOne registration rights in relation to such shares and
preferred stock. AirTouch also assumed approximately $1.4 billion of
indebtedness, which it refinanced, and assumed the guarantee obligations
executed by MediaOne in relation to certain leveraged leases entered into by
PrimeCo.
 
                                      E-10
<PAGE>
    In accordance with post-closing adjustments to the merger consideration as
set out in the MediaOne Agreement, in September 1998 MediaOne returned to
AirTouch, as a first and final adjustment, approximately 130,000 AirTouch Common
Shares with a then market value of $7.9 million.
 
    AirTouch and MediaOne also gave certain representations and warranties to
each other and indemnified each other against certain losses to the extent they
exceed $40 million up to a maximum amount of $750 million, which arise from
claims made in the 18 months from the effective date of the MediaOne Agreement.
 
    The parties to the MediaOne Agreement also agreed to enter into various
ancilliary agreements before the closing date of the MediaOne Agreement,
including patent and software licensing agreements, a tax sharing agreement and
a new investment agreement.
 
14. LITIGATION
 
    14.1 No member of the Vodafone Group is or has been engaged in any legal or
arbitration proceedings which may have, or have had during the 12 months
preceding the date of this document, a significant effect on the Vodafone
Group's financial position nor, so far as the Directors are aware, are any such
proceedings pending or threatened.
 
    14.2 Other than as set out in Sections 14.3 to 14.9 below, no member of the
AirTouch Group is or has been engaged in any legal or arbitration proceedings
which may have, or have had during the 12 months preceding the date of this
document, a significant effect on the AirTouch Group's consolidated financial
position nor, so far as AirTouch is aware, are any such proceedings pending or
threatened.
 
    14.3 AirTouch is a defendant in various antitrust lawsuits filed in both
state and federal courts in the U.S. In 1993, a class action complaint was filed
in the State of California in the Orange County Superior Court. The plaintiffs
alleged that AirTouch was involved in price fixing in the Los Angeles cellular
market. In 1994, a parallel class action complaint, also filed in Orange County
Superior Court, was stayed pending the resolution of the 1993 case. In 1997, the
same court approved a settlement of the 1993 case, although three plaintiffs
have filed an appeal challenging the adequacy of the settlement.
 
    14.4 In December 1998, a complaint was filed against AirTouch and other
cellular service providers in the State of California in the Sacramento County
Superior Court on behalf of all individuals subscribing to service in the
Sacramento area. The plaintiffs claimed that the defendants conspired to fix
prices for cellular services and sought injunctive relief and damages in excess
of $100 million. This case is at a preliminary stage of proceedings and AirTouch
is not able to assess the impact, if any, of these cases on its current
financial position or results of operations.
 
    14.5 In July 1998, customers filed a further complaint in the Sacramento
County Superior Court against AirTouch and other cellular and PCS carriers
challenging the legality of certain billing practices and claiming that the
practices are not adequately disclosed in the California markets. This case was
subsequently dismissed with prejudice. The plaintiffs have filed a notice of
appeal. In August 1998, a complaint was filed against PrimeCo, an unconsolidated
subsidiary of AirTouch, in the Cook County Chancery Court. The plaintiffs are
challenging the legality of certain billing practices and claiming that the
practices are not adequately disclosed. The plaintiffs are seeking unspecified
monetary damages and revisions of PrimeCo's billing practices. Also in August
1998, a second complaint was filed against PrimeCo in the Cook County Chancery
Court alleging certain deficiencies in PrimeCo's network performance. The
plaintiffs are seeking unspecified monetary damages. These cases are at
preliminary stages of proceedings. AirTouch is not able to assess the impact, if
any, of these cases on its financial position or results of operations.
 
    14.6 On 6 January 1999, a class action was filed against AirTouch in the
Federal District Court for the Central District of California alleging claims
under section 10(b) and 20(a) of the Securities
 
                                      E-11
<PAGE>
Exchange Act, 15 U.S.C. 78j and 78t and Rule 10b-5. The action was filed on
behalf of individuals who sold AirTouch Common Shares or call options or
purchased put options on 4 January 1999. The plaintiffs claim that AirTouch's
press release on 3 January 1999 was false and misleading because it confirmed
that AirTouch was in discussions with Bell Atlantic but did not disclose that it
was in discussions with Vodafone. The plaintiffs are seeking unspecified
monetary damages. This case is at a preliminary stage of proceedings and
AirTouch is not able to assess the impact, if any, on its current financial
position or results of operations.
 
    14.7 Bell Atlantic filed an action against AirTouch on 15 January 1999 in
the Federal District Court for the Northern District of California seeking an
injunction to void clauses of the TOMCOM, L.P. and PrimeCo partnership
agreements which restrict a partner's ability to compete against the
partnerships. AirTouch has filed a counterclaim against Bell Atlantic for
violations of the partnership agreements. The case is at a preliminary stage of
proceedings and AirTouch is not able to assess the impact, if any, on its
current financial position or results of operations.
 
    14.8 In March 1999, customers filed a class action complaint in Los Angeles
County Superior Court against AirTouch challenging the legality of the
assessment of an early disconnection charge when a customer terminates service
under a contract whose duration has been extended upon the acceptance of a new
promotional offer. The plaintiffs are seeking injunctive relief and unspecified
monetary damages, including disgorgement of monies obtained as a result of the
alleged unlawful business practices. This case is at a preliminary stage of
proceedings and AirTouch is not currently able to assess the impact, if any, on
its financial position or results of operations.
 
    14.9 In April 1999, a complaint was filed against AirTouch in the State of
Michigan on behalf of all individuals subscribing to service in that state. The
plaintiffs are challenging the legality of AirTouch's assessment of certain
charges for local calls and charges for calls that pass through wireline
networks. The plaintiffs are seeking injunctive relief and unspecified monetary
damages. This case is at a preliminary stage of proceedings and AirTouch is not
currently able to assess the impact, if any, of this case on its financial
position or results of operations.

                     SUBCHAPTER IX. MERGER OR CONSOLIDATION
 
Section 262 APPRAISAL RIGHTS.
 
    (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to Section 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.
 
    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section251 (other than a merger effected pursuant to
Section251(g) of this title), Section252, Section254, Section257, Section258,
Section263 or Section264 of this title:
 
        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of Section251 of this title.
 
        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to Sections
    251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock

       such merger or consolidation, or depository receipts in respect thereof;
 
           b. Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock (or depository receipts in
       respect thereof) or depository receipts at the effective date of the
       merger or consolidation will be either listed on a national securities
       exchange or designated as a national market system security on an
       interdealer quotation system by the National Association of Securities
       Dealers, Inc. or held of record by more than 2,000 holders;
 
           c. Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or
 
                                      F-1
<PAGE>
           d. Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.
 
        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under Section253 of this title is not owned by
    the parent corporation immediately prior to the merger, appraisal rights
    shall be available for the shares of the subsidiary Delaware corporation.
 
    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
    (d) Appraisal rights shall be perfected as follows:
 
        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsections (b) or (c) hereof that appraisal rights are
    available for any or all of the shares of the constituent corporations, and
    shall include in such notice a copy of this section. Each stockholder
    electing to demand the appraisal of such stockholder's shares shall deliver
    to the corporation, before the taking of the vote on the merger or
    consolidation, a written demand for appraisal of such stockholder's shares.
    Such demand will be sufficient if it reasonably informs the corporation of
    the identity of the stockholder and that the stockholder intends thereby to
    demand the appraisal of such stockholder's shares. A proxy or vote against
    the merger or consolidation shall not constitute such a demand. A
    stockholder electing to take such action must do so by a separate written
    demand as herein provided. Within 10 days after the effective date of such
    merger or consolidation, the surviving or resulting corporation shall notify
    each stockholder of each constituent corporation who has complied with this
    subsection and has not voted in favor of or consented to the merger or
    consolidation of the date that the merger or consolidation has become
    effective; or
 
        (2) If the merger or consolidation was approved pursuant to Section228
    or Section253 of this title, each constituent corporation, either before the
    effective date of the merger or consolidation or within ten days thereafter,
    shall notify each of the holders of any class or series of stock of such
    constituent corporation who are entitled to appraisal rights of the approval
    of the merger or consolidation and that appraisal rights are available for
    any or all shares of such class or series of stock of such constituent
    corporation, and shall include in such notice a copy of this section;
    provided that, if the notice is given on or after the effective date of the
    merger or consolidation, such notice shall be given by the surviving or
    resulting corporation to all such holders of any class or series of stock of
    a constituent corporation that are entitled to appraisal rights. Such notice
    may, and, if given on or after the effective date of the merger or
    consolidation, shall, also notify such stockholders of the effective date of
    the merger or consolidation. Any stockholder entitled to appraisal rights
    may, within 20 days after the date of mailing of such notice, demand in
    writing from the surviving or resulting corporation the appraisal of such
    holder's shares. Such demand will be sufficient if it reasonably informs the
    corporation of the identity of the stockholder and that the stockholder
    intends thereby to demand the appraisal of such holder's shares. If such
    notice did not notify stockholders of the effective date of the merger or
    consolidation, either (i) each such constituent corporation shall send a
    second notice before the effective date of the merger or consolidation
    notifying each of the holders of any class or series of stock of such
    constituent
 
                                      F-2
<PAGE>
    corporation that are entitled to appraisal rights of the effective date of
    the merger or consolidation or (ii) the surviving or resulting corporation
    shall send such a second notice to all such holders on or within 10 days
    after such effective date; provided, however, that if such second notice is
    sent more than 20 days following the sending of the first notice, such
    second notice need only be sent to each stockholder who is entitled to
    appraisal rights and who has demanded appraisal of such holder's shares in
    accordance with this subsection. An affidavit of the secretary or assistant
    secretary or of the transfer agent of the corporation that is required to
    give either notice that such notice has been given shall, in the absence of
    fraud, be prima facie evidence of the facts stated therein. For purposes of
    determining the stockholders entitled to receive either notice, each
    constituent corporation may fix, in advance, a record date that shall be not
    more than 10 days prior to the date the notice is given, PROVIDED, THAT, if
    the notice is given on or after the effective date of the merger or
    consolidation, the record date shall be such effective date. If no record
    date is fixed and the notice is given prior to the effective date, the
    record date shall be the close of business on the day next preceding the day
    on which the notice is given.
 
    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.
 
    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
                                      F-3
<PAGE>
    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.
 
    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.
 
    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.
