corporation ("MediaOne Group"), proposes to sell to the underwriters named in
Schedule I hereto (the "Underwriters"), for whom you (the "Representatives") are

*  Plus an option to purchase from MediaOne Group, Inc. up to 3,900,000

<PAGE>

The First National Bank of Chicago, as trustee (the "Trustee"), as amended to 
the date hereof by the First Supplemental Indenture thereto dated as of 
December 6, 1995, the Second Supplemental Indenture thereto dated as of May 
8, 1996 and the Third Supplemental Indenture thereto dated as of August 5, 
1998.  In addition, the Underwriters will have an option to purchase up to 
3,900,000 PIES (the "Option PIES" and, together with the Underwritten PIES, 
the "PIES").  At maturity (including as a result of acceleration or 
otherwise), the PIES will be mandatorily exchanged by MediaOne Group into 
shares of Common Stock, par value $.01 per share (the "AirTouch Common 
Stock"), of AirTouch Communications, Inc., a Delaware corporation 
("AirTouch") (or, at MediaOne Group's option under the circumstances 
described in the Final MediaOne Group Prospectus (as defined below), the cash 
equivalent for all or part thereof and/or such other consideration as 
permitted or required by the terms of the PIES) at the rate specified in the 
Final MediaOne Group Prospectus.

     In connection with the foregoing and pursuant to the Investment 
Agreement dated April 6, 1998 between AirTouch and MediaOne Group (the 
"Investment Agreement"), AirTouch has filed with the Commission a shelf 
registration statement (including a base prospectus), pursuant to Rule 415 
and has filed a preliminary prospectus pursuant to Rule 424 with respect to a 
number of shares (the "Underwritten Shares") of AirTouch Common Stock offered 
pursuant to the Underwritten PIES plus an additional number of shares (the 
"Option Shares" and, together with the Underwritten Shares, the "Shares") of 
AirTouch Common Stock offered pursuant to the Option PIES, for sale by 
MediaOne Group as a selling stockholder (to the extent MediaOne Group shall 
so elect to deliver AirTouch Common Stock at maturity to holders of the PIES 
pursuant to the terms of the PIES), which registration statement is referred 
to in Section 2 of this Agreement.

     Certain terms used in this Agreement are defined in paragraph (a)(vi) of 
Section 1 and paragraph (c) of Section 2.

     1.   REPRESENTATIONS AND WARRANTIES OF MEDIAONE GROUP.  (a) MediaOne
Group represents and warrants to, and agrees with, each Underwriter and AirTouch

            (i) MediaOne Group has filed with the Commission registration 
       statements (file number 33-62451, 333-57187 and 333-59587) on Form 
       S-3, including a basic prospectus, for the registration under the 
       Securities Act of 1933, as amended (the "Act"), of the offering and 
       sale of the PIES. MediaOne Group may have filed one or more amendments 
       thereto, and may have used a Preliminary Final MediaOne Group 
       Prospectus, each of which has previously been furnished to you and to 
       AirTouch.  Such registration statement, as so amended, has become 
       effective.  MediaOne Group will next file with the Commission pursuant 
       to Rules 415 and 424(b)(2) or (5) a final supplement to the form of 
       prospectus included in such registration statement relating to the 
       PIES and the offering thereof.  As filed, such final prospectus 
       supplement, except to the extent the Representatives (and, as to 
       modifications to AirTouch Furnished Information, AirTouch) shall agree 
       in writing to a modification, shall be in all substantive respects in 
       the form 

                                            2

       extent not completed at the Execution Time, shall contain only such 
       specific additional information and other changes (beyond that 
       contained in the Basic MediaOne Group Prospectus and any Preliminary 
       Final MediaOne Group Prospectus) as MediaOne Group has advised you and 
       AirTouch, prior to the Execution Time, will be included or made 
       therein.

             (ii)     On the MediaOne Group Effective Date, the MediaOne

       respective rules thereunder; on the MediaOne Group Effective Date, the 
       MediaOne Group Registration Statement did not or will not 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 not misleading; on the MediaOne Group Effective 
       Date and on the Closing Date the Indenture did or will comply in all 
       material respects with the applicable requirements of the Trust 
       Indenture Act and the rules thereunder; and, on the date of any filing 
       pursuant to Rule 424(b) and on the Closing Date, the Final MediaOne 
       Group Prospectus (together with any supplement thereto) will not 
       include any untrue statement of a material fact or omit to state a 
       material fact necessary in order to make the statements therein, in 
       the light of the circumstances under which they were made, not 
       misleading; PROVIDED, HOWEVER, that MediaOne Group makes no 
       representations or warranties as to (A) that part of the MediaOne 
       Group Registration Statement which shall constitute the Statement of

       MediaOne Group Registration Statement or the Final MediaOne Group

       thereto) or (C) the information contained in or omitted from the Final 
       MediaOne Group Prospectus (or any supplement thereto) in reliance upon

       information is presented in the MediaOne Group Registration Statement 
       and the Final MediaOne Group Prospectus, except as otherwise stated 
       therein, there has been no material adverse change or any development 
       involving a prospective material adverse change in the financial 
       condition or results of operations of MediaOne Group and its 
       subsidiaries taken as a whole ("MediaOne Material Adverse Effect").

           (iv)     To the knowledge of MediaOne Group, the representations

       are (i) in cases where such representations and warranties are

    Item 12 of Form S-3 which were filed under the Exchange Act on or before

    shall be deemed to refer to and include the filing of any document under 
    the Exchange Act after the AirTouch Effective Date, or the issue date of 
    any Preliminary Final AirTouch Prospectus or the Final AirTouch 
    Prospectus, as the case may be, deemed to be incorporated therein by 
    reference.  The term "Material Adverse Effect" shall mean a material 
    adverse change or any development involving a prospective material 
    adverse change in the financial condition or results of operations of 
    AirTouch and its consolidated subsidiaries, taken as a whole.

          (d)  Each of AirTouch and each of AirTouch Cellular, a California 
    corporation, AirTouch of Nevada, a Nevada corporation, AirTouch Cellular, 
    Inc., a Delaware corporation, and AirTouch International, a California 
    corporation, (each individually a "AirTouch Subsidiary" and collectively 
    the "AirTouch Subsidiaries") is validly existing as a corporation in good 
    standing under the laws of the jurisdiction in which it is chartered or 
    organized.  Each of AirTouch and the AirTouch Subsidiaries has been duly 
    incorporated and has full corporate power and authority to own its 
    properties and conduct its business as described in the Final AirTouch 
    Prospectus.  Each of AirTouch and the AirTouch Subsidiaries is duly 
    qualified to do business as a foreign corporation and is in good standing 
    under the laws of each jurisdiction in which the ownership or leasing of 
    its properties or the conduct of its business legally require such 
    qualification, except where the failure so to qualify or be in good 
    standing would not have a Material Adverse Effect.

          (e)  There are no options, warrants or other rights to subscribe 
    for, to purchase or to convert any obligations into or exchange any 
    securities for, any shares of capital stock of the Company pursuant to 
    the Company's articles of incorporation, by-laws or other governing 
    documents or any agreement or other instrument to which the Company or 
    any of the AirTouch Subsidiaries is a party or by which any of them may 
    be bound, except as disclosed in the Final AirTouch Prospectus.  Neither 
    the filing of the AirTouch Registration Statement nor the offering or 
    sale of the Shares as contemplated by this Agreement gives rise to any 
    rights, other than those which have been waived or satisfied, for or 
    relating to the registration of any shares of AirTouch Common Stock or 
    other securities of AirTouch.  The capitalization of AirTouch as of June 
    30, 1998 is as set forth in the AirTouch Final Prospectus and the 
    AirTouch Common Stock conforms to the description thereof contained in 
    the AirTouch Prospectus.  All of the outstanding shares of capital stock 
    of each AirTouch Subsidiary have been duly authorized and validly issued, 
    are fully paid and nonassessable, and, except as otherwise set forth in 
    the AirTouch Final Prospectus, are owned by AirTouch, directly or through 
    wholly owned subsidiaries, free and clear of any claim, lien, 
    encumbrance, security interest, restriction upon voting or transfer, 
    preemptive rights or any other claim of any third party.

          (f)  (i) None of the execution or delivery of this Agreement, the 
    sale of the Shares pursuant to the PIES, or the consummation by AirTouch 
    of the transactions contemplated hereby will conflict with, result in a 
    breach or violation of, or constitute a default under (A) the articles of 
    incorporation, by-laws or other governing documents of AirTouch or any of 
    the AirTouch Subsidiaries or (B) any material agreement, indenture or 
    other instrument, to which any of them is a party or by which any of them 
    is bound, or to which 

                                            8
<PAGE>


    any of their properties is subject (except in the case of this clause (B) 
    for such conflicts, breaches, violations and defaults that would not 
    result in a Material Adverse Effect) and (ii) the performance by AirTouch 
    of its obligations hereunder will not violate in any material respect any 
    law, rule, administrative regulation or decree of any court, governmental 
    agency, regulatory body or other governmental body, or any arbitrator 
    having jurisdiction over AirTouch, the AirTouch Subsidiaries or any of 
    their respective properties, or result in the creation or imposition of 
    any material lien, charge, claim or encumbrance upon any property or 
    asset of AirTouch or any of the AirTouch Subsidiaries (except for such 
    liens, charges and encumbrances that would not have a Material Adverse 
    Effect).  Except for permits and similar authorizations required under 
    the Act and the securities or "Blue Sky" laws of certain jurisdictions 
    and for such permits and authorizations which have been obtained, no 
    consent, approval, authorization or order of any court, governmental 
    agency, regulatory body or other governmental body or financial 
    institution is required in connection with the consummation by AirTouch 
    of the transactions contemplated by this Agreement.

          (g)  This Agreement has been duly authorized, executed and 
    delivered by AirTouch.

          (h)  No action, suit or proceeding by or before any court or any 
    governmental agency, regulatory body or other governmental body or any 
    arbitrator involving AirTouch or any its subsidiaries, or any of their 
    respective properties is pending or threatened that (i) may have a 
    material adverse effect on the performance of this Agreement by AirTouch 
    or the consummation by AirTouch of any of the transactions contemplated 
    hereby or (ii) may have a Material Adverse Effect (except, in the case of 
    this clause (ii) for those that have been disclosed in the Final AirTouch 
    Prospectus); and there is no franchise, contract or other document of a 
    character required to be described in the AirTouch Registration Statement 
    or Final AirTouch Prospectus, or to be filed as an exhibit, which is not 
    described or filed as required.

          (i)  AirTouch has not taken and shall not take, directly or 
    indirectly, any action designed to cause or result in, or which has 
    constituted or which might reasonably be expected to constitute, the 
    stabilization or manipulation of the price of the shares of AirTouch 
    Common Stock to facilitate the resale by MediaOne Group of the Shares 
    pursuant to the offering of the PIES.

          (j)  AirTouch is not an "investment company" within the meaning of 
    such term under the Investment Company Act of 1940 as amended, and the 
    rules and regulations thereunder.

     3.   PURCHASE AND SALE.  (a) Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, MediaOne
Group agrees to sell to each Underwriter, and each Underwriter agrees, severally
and not jointly, to purchase from MediaOne Group, the number of PIES set forth

     (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, MediaOne Group hereby grants an
option to the several Underwriters to purchase, severally and not jointly, up to
3,900,000 of the Option PIES at the same purchase price as the Underwriters
shall pay for the Underwritten PIES.  Said option may be exercised only to cover
over-allotments in the sale of the Underwritten PIES by the Underwriters.  Said
option may be exercised in whole or in part at any time (but not more than once)
on or before the 30th day after the date of the Final MediaOne Group Prospectus
upon written or telegraphic notice by the Representatives to MediaOne Group
setting forth the number of the Option PIES as to which the several Underwriters
are exercising the option and the settlement date.  Delivery of certificates for
the Option PIES, and payment therefor, shall be made as provided in Section 4
hereof.  The number of the Option PIES to be purchased by each Underwriter shall
be the same percentage of the total number of the Option PIES to be purchased by
the several Underwriters as such Underwriter is purchasing of the Underwritten
PIES, subject to such adjustments as you in your absolute discretion shall make
to eliminate any fractional Option PIES.

     4.   DELIVERY AND PAYMENT.  Delivery of and payment for the
Underwritten PIES and the Option PIES (if the option provided for in
Section 3(b) hereof shall have been exercised on or before the second business
day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
August 5, 1998, (or such later date not later than five business days after such
specified date as the Representatives shall designate) which date and time may
be postponed by agreement between the Representatives and MediaOne Group or as
provided in Section 11 hereof (such date and time of delivery and payment for
the PIES being herein called the "Closing Date").  Delivery of the PIES shall be
made to the Representatives for the respective accounts of the several
Underwriters against payment by the several Underwriters through the
Representatives of the purchase price thereof to or upon the order of MediaOne
Group by wire transfer of same day funds to an account specified by MediaOne
Group on or before the second business day prior to the Closing Date.  Delivery
of the PIES shall be made through the facilities of the Depositary Trust
Company, unless the Representatives otherwise instruct.  Certificates for the
PIES shall be registered in such names and in such denominations as the
Representatives may request not less than two full business days in advance of
the Closing Date.

     If the option provided for in Section 3(b) hereof is exercised after
the second business day prior to the Closing Date, MediaOne Group will deliver
the Option PIES (at the expense of MediaOne Group) to the Representatives
through the facilities of the Depositary Trust Company on the date specified by
the Representatives (which shall be within three business days after exercise of
said option) to the Representatives against payment of the purchase price
thereof to or upon the order of MediaOne Group by wire transfer of funds payable
in same day funds to the above-mentioned account specified by MediaOne Group. 
If settlement for the Option PIES occurs after the Closing Date, MediaOne Group
and AirTouch will deliver to the Representatives on the settlement date for the
Option PIES, and the obligation of the Underwriters to purchase the Option PIES
shall be conditioned upon receipt of, supplemental opinions, certificates and
letters confirming as of such date the opinions, certificates and letters
delivered on the Closing Date pursuant to Section 7 hereof.

     5.   OFFERING BY UNDERWRITERS.  It is understood that the several
Underwriters propose 

                                            10
<PAGE>


to offer the PIES for sale to the public as set forth in the Final MediaOne 
Group Prospectus.

     6.   AGREEMENTS OF MEDIAONE GROUP.  MediaOne Group agrees with the
several Underwriters that:

          (a) MediaOne Group will use its best efforts to cause the MediaOne 
    Group Registration Statement, if not effective at the Execution Time, and 
    any amendment thereof to become effective.  Prior to the termination of 
    the offering of the PIES, MediaOne Group will not file any amendment of 
    the MediaOne Group Registration Statement or supplement (including the 
    Final MediaOne Group Prospectus or any Preliminary Final MediaOne Group 
    Prospectus) to the Basic MediaOne Group Prospectus unless MediaOne Group 
    has furnished you a copy for your review prior to filing and will not 
    file any such proposed amendment or supplement to which you reasonably 
    object unless MediaOne Group shall conclude in good faith that such 
    filing is required by applicable law.  Subject to the foregoing sentence, 
    MediaOne Group will cause the Final MediaOne Group Prospectus, properly 
    completed, and any supplement thereto to be filed with the Commission 
    pursuant to the applicable paragraph of Rule 424(b) within the time 
    period prescribed and will provide evidence satisfactory to the 
    Representatives of such timely filing.  MediaOne Group will promptly 
    advise the Representatives (i) when the MediaOne Group Registration 
    Statement, if not effective at the Execution Time, and any amendment 
    thereto, shall have become effective, (ii) when the Final MediaOne Group 
    Prospectus, and any supplement thereto, shall have been filed with the 
    Commission pursuant to Rule 424(b), (iii) when, prior to termination of 
    the offering of the PIES, any amendment to the MediaOne Group 
    Registration Statement shall have been filed or become effective, (iv) of 
    any request by the Commission for any amendment of the MediaOne Group 
    Registration Statement or supplement to the Final MediaOne Group 
    Prospectus or for any additional information, (v) of the issuance by the 
    Commission of any stop order suspending the effectiveness of the MediaOne 
    Group Registration Statement or the institution or threatening of any 
    proceeding for that purpose and (vi) of the receipt by MediaOne Group of 
    any notification with respect to the suspension of the qualification of 
    the PIES for sale in any jurisdiction or the initiation or threatening of 
    any proceeding for such purpose.  MediaOne Group will use its best 
    efforts to prevent the issuance of any such stop order and, if issued, to 
    obtain as soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the PIES is 
    required to be delivered under the Act, any event occurs as a result of 
    which the Final MediaOne Group Prospectus as then supplemented would 
    include any untrue statement of a material fact or omit to state any 
    material fact necessary to make the statements therein in the light of 
    the circumstances under which they were made not misleading, or if it 
    shall be necessary to amend the MediaOne Group Registration Statement or 
    supplement the Final MediaOne Group Prospectus to comply with the Act or 
    the Exchange Act or the respective rules thereunder, MediaOne Group 
    promptly will prepare and file with the Commission, subject to the second 
    sentence of paragraph (a) of this Section 6, an amendment or supplement 
    which will correct such statement or omission or effect such compliance.

                                            11
<PAGE>

          (c)  As soon as practicable, MediaOne Group will make generally 
    available to its security holders an earnings statement or statements of 
    MediaOne Group and its subsidiaries which will satisfy the provisions of 
    Section 11(a) of the Act and Rule 158 under the Act.

          (d) MediaOne Group will furnish to the Representatives and counsel 
    for the Underwriters, without charge, copies of the MediaOne Group 
    Registration Statement (including exhibits thereto) and to each other 
    Underwriter a copy of the MediaOne Group Registration Statement (without 
    exhibits thereto) and, so long as delivery of a prospectus by an 
    Underwriter or dealer may be required by the Act, as many copies of each 
    Preliminary Final MediaOne Group Prospectus and the Final MediaOne Group 
    Prospectus and any supplement thereto as the Representatives may 
    reasonably request.  MediaOne Group will pay the expenses of printing or 
    other production of the MediaOne Group Registration Statement, each 
    Preliminary Final MediaOne Group Prospectus and the Final MediaOne Group 
    Prospectus (other than with respect to the Preliminary Final AirTouch 
    Prospectus and Final AirTouch Prospectus, respectively, attached a 
    thereto, which shall be paid by AirTouch).

          (e)  MediaOne Group will arrange for the qualification of the PIES 
    and the Shares for sale under the laws of such jurisdictions as the 
    Representatives may designate and will maintain such qualifications in 
    effect so long as required for the distribution of the PIES and the 
    Shares; provided, however, that in connection therewith MediaOne Group 
    shall not be required to qualify as a foreign corporation or to file a 
    general consent to service of process in any jurisdiction.

          (f)  MediaOne Group will not, for a period of 90 days following the 
    Execution Time, without the prior written consent of Lehman Brothers 
    Inc., offer for sale, sell or contract to sell, or otherwise dispose of, 
    or announce the offering of, or file or cause the filing of any 
    registration statement under the Securities Act with respect to, any 
    shares of AirTouch Common Stock or any securities convertible into, or 
    exchangeable for, or warrants to acquire, shares of AirTouch Common Stock 
    (other than the PIES).

     7.   AGREEMENTS OF AIRTOUCH.  AirTouch agrees with the several
Underwriters that:

          (a)  AirTouch will use its best efforts to cause the AirTouch 
    Registration Statement, if not effective at the Execution Time, and any 
    amendment thereof to become effective.  Prior to the termination of the 
    offering of the PIES, AirTouch will not file any amendment of the 
    AirTouch Registration Statement or supplement (including the Final 
    AirTouch Prospectus) to the Preliminary Final AirTouch Prospectus or the 
    Final AirTouch Prospectus unless AirTouch has furnished you a copy for 
    your review prior to filing and will not file any such proposed amendment 
    or supplement to which you reasonably object unless AirTouch shall 
    conclude in good faith that such filing is required by applicable law.  
    Subject to the foregoing sentence, AirTouch will cause the Final AirTouch 
    Prospectus, properly completed, and any supplement thereto to be filed 
    with the Commission pursuant to the applicable paragraph of Rule 424(b) 
    within the time 

                                            12
<PAGE>

    period prescribed and will provide evidence satisfactory to the 
    Representatives of such timely filing.  AirTouch will promptly advise the 
    Representatives (i) when the AirTouch Registration Statement, if not 
    effective at the Execution Time, and any amendment thereto, shall have 
    become effective, (ii) when the Final AirTouch Prospectus, and any 
    supplement thereto, shall have been filed with the Commission pursuant to 
    Rule 424(b), (iii) when, prior to termination of the offering of the 
    Shares, any amendment to the AirTouch Registration Statement shall have 
    been filed or become effective, (iv) of any request by the Commission for 
    any amendment of the AirTouch Registration Statement or supplement to the 
    Final AirTouch Prospectus or for any additional information, (v) of the 
    issuance by the Commission of any stop order suspending the effectiveness 
    of the AirTouch Registration Statement or the institution or threatening 
    of any proceeding for that purpose and (vi) of the receipt by AirTouch of 
    any notification with respect to the suspension of the qualification of 
    the Shares for sale in any jurisdiction or the initiation or threatening 
    of any proceeding for such purpose.  AirTouch will use its best efforts 
    to prevent the issuance of any such stop order and, if issued, to obtain 
    as soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Shares is 
    required to be delivered under the Act (i) any event occurs as a result 
    of which the Final AirTouch Prospectus as then supplemented would include 
    any untrue statement of a material fact or omit to state any material 
    fact necessary to make the statements therein in the light of the 
    circumstances under which they were made not misleading, or (ii) it shall 
    be necessary to amend the AirTouch Registration Statement or supplement 
    the Final AirTouch Prospectus to comply with the Act or the Exchange Act 
    or the respective rules thereunder, AirTouch will promptly notify the 
    Underwriters and will promptly prepare and file with the Commission, 
    subject to the second sentence of paragraph (a) of this Section 7, an 
    amendment or supplement which will correct such statement or omission or 
    effect such compliance.

          (c)  As soon as practicable, AirTouch will make generally available 
    to its security holders and to the Representatives an earnings statement 
    or statements of AirTouch and its consolidated subsidiaries which will 
    satisfy the provisions of Section 11(a) of the Act and Rule 158 under the 
    Act.

          (d)  AirTouch will furnish to the Representatives and counsel for 
    the Underwriters, without charge, copies of the AirTouch Registration 
    Statement (including exhibits thereto) and to each other Underwriter a 
    copy of the AirTouch Registration Statement (without exhibits thereto) 
    and, so long as delivery by an Underwriter or dealer of a prospectus with 
    respect to the PIES may be required by the Act, as many copies of each 
    Preliminary Final AirTouch Prospectus and the Final AirTouch Prospectus 
    and any supplement thereto as the Representatives may reasonably request. 
     AirTouch will pay the expenses of printing or other production of the 
    AirTouch Registration Statement, each Preliminary Final AirTouch 
    Prospectus and the Final AirTouch Prospectus.

          (e)  AirTouch will cooperate with MediaOne Group for purposes of 
    the qualification 

                                            13
<PAGE>

    of the PIES and the Shares for sale under the laws of such jurisdictions 
    as the Representatives may designate and will use all reasonable efforts 
    to maintain such qualifications in effect so long as required for the 
    sale of the Shares pursuant to the distribution of the PIES; provided, 
    however, that in connection therewith, AirTouch shall not be required to 
    qualify to do business in any jurisdiction where it is now not qualified 
    or to take any action which would subject it to general or unlimited 
    service of process, or to taxation, in any jurisdiction where it is not 
    now so subject.

          (f)  AirTouch will not, for a period of 90 days following the 
    Execution Time, without the prior written consent of Lehman Brothers 
    Inc., offer for sale, sell or contract to sell, or otherwise dispose of, 
    or announce the offering of, or file or cause the filing of any 
    registration statement under the Securities Act with respect to, (i) any 
    shares of AirTouch Common Stock or any securities convertible into, or 
    exchangeable for, or warrants to acquire, shares of AirTouch Common Stock 
    (other than the Shares in connection with the offering by MediaOne Group 
    of the PIES); PROVIDED, HOWEVER, that AirTouch may sell AirTouch Common 
    Stock or grant options to purchase the same, in either case, pursuant to 
    any employee stock option plan, stock ownership plan or dividend 
    reinvestment plan of AirTouch in effect at the Execution Time.

          (g)  AirTouch will furnish to the Trustee copies of its annual 
    report to stockholders and reports on Forms 10-K and 10-Q in sufficient 
    quantities for transmission to holders of the PIES as soon as practicable 
    after such reports are required to be filed with the Commission.  The 
    cost of production of such reports will be borne by AirTouch and the cost 
    of transmitting such reports to the holders will be borne by MediaOne 
    Group.

          (h)  AirTouch will take such actions as may be reasonably necessary 
    to comply with the rules and regulations of the NYSE in respect of the 
    offering of the Shares contemplated hereby.

     8.   CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS.  The obligations 
of the Underwriters to purchase the PIES shall be subject to the accuracy of 
the representations and warranties on the part of MediaOne Group and AirTouch

     (b)  MediaOne Group shall have furnished to the Representatives the

           (i) each of MediaOne Group and the MediaOne Group Subsidiary has 
     been duly incorporated and is validly existing as a corporation in good 
     standing under the laws of the jurisdiction in which it is organized, 
     with full corporate power and authority to own its properties and 
     conduct its business as described in the Final MediaOne Group 
     Prospectus, and is duly qualified to do business as a foreign 
     corporation and is in good standing under the laws of each jurisdiction 
     which requires such qualification wherein it owns or leases material 
     properties or conducts material business, except where failure to so 
     qualify would not have a material adverse effect on MediaOne Group and 
     the MediaOne Group Subsidiary, taken as a whole;

            (ii)     no consent, approval, authorization or order of any 
     court or governmental agency or body is required for the consummation of 
     the transactions contemplated herein, except such as have been obtained 
     under the Act and such as may be required under the blue sky laws of any 
     jurisdiction in connection with the distribution of the PIES and the 
     Shares by MediaOne Group and such other approvals (specified in such 
     opinion) as have been obtained; and

           (iii)    to the best knowledge of such counsel, MediaOne Group has 
     good and marketable title to the Shares and owns such Shares free and 
     clear of all liens, encumbrances, equities and claims.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the State of Colorado or the
United States, to the extent such counsel deems proper and specified in such
opinion, the State of Delaware, upon the opinion of other counsel of good
standing whom such counsel believes to be reliable and who are satisfactory to
counsel for the Underwriters and (B) as to matters of fact, to the extent such
counsel deems proper, on certificates of responsible officers of MediaOne Group
and public officials.  References to the Final MediaOne Group Prospectus in this
paragraph (b) include any supplements thereto at the Closing Date.

       (c)  MediaOne Group shall have furnished to the Representatives the
opinion of Weil, Gotshal & Manges, counsel for MediaOne Group, dated as of the
Closing Date, to the effect that:

      (i) MediaOne Group has been duly incorporated and is validly existing
as a corporation in good standing under the laws of the State of Delaware,
with full corporate 

                                            15
<PAGE>


     power and authority to own its properties and conduct its business as 
     described in the Final MediaOne Group Prospectus;

          (ii)   the Indenture has been duly authorized, executed and 
     delivered, has been duly qualified under the Trust Indenture Act, and 
     (assuming the due authorization, execution and delivery thereof by the 
     Trustee) constitutes a legal, valid and binding instrument enforceable 
     against MediaOne Group in accordance with its terms (subject, as to 
     enforcement of remedies, to applicable bankruptcy, reorganization, 
     insolvency, moratorium or other laws affecting creditors' rights 
     generally from time to time in effect); and the PIES have been duly 
     authorized and, when executed and authenticated in accordance with the 
     provisions of the Indenture and delivered to and paid for by the 
     Underwriters pursuant to this Agreement will constitute legal, valid and 
     binding obligations of MediaOne Group entitled to the benefits of the 
     Indenture;

           (iii)    the MediaOne Group Registration Statement was declared 
     effective under the Act; any required filing of the Basic MediaOne Group 
     Prospectus, any Preliminary Final MediaOne Group Prospectus and the 
     Final MediaOne Group Prospectus, and of any supplements thereto, 
     pursuant to Rule 424(b) has been made in the manner and within the time 
     period required by Rule 424(b); to the best knowledge of such counsel, 
     no stop order suspending the effectiveness of the MediaOne Group 
     Registration Statement has been issued, no proceedings for that purpose 
     have been instituted or threatened;

           (iv)     this Agreement has been duly authorized, executed and 
     delivered by MediaOne Group; and

           (v) The statements in the Basic MediaOne Group Prospectus under 
     the heading "Description of Debt Securities" and the statements in the 
     Final MediaOne Group Prospectus under the heading "Description of the 
     PIES", insofar as such statements constitute a summary of certain 
     provisions of the Indenture and the PIES, are accurate in all material 
     respects.

     In addition, such counsel shall state that it has participated in
conferences with officers and other representatives of MediaOne Group,
representatives of the independent public accountants for MediaOne Group and
representatives of the Underwriters and counsel for the Underwriters, at which
conferences the contents of the MediaOne Group Registration Statement and the
Final MediaOne Group Prospectus and related matters were discussed; such counsel
has not independently verified and is not passing upon and assumes no
responsibility for the accuracy, completeness or fairness of the statements
contained in the MediaOne Group Registration Statement and the Final MediaOne
Group Prospectus, except for the statements in the Basic MediaOne Group
Prospectus under the heading "Description of Debt Securities" and the statements
in the Final MediaOne Group Prospectus under the heading "Description of the
PIES"; however, based upon such counsel's participation in the aforesaid
conferences, no facts have come to its attention which lead it to believe that
the MediaOne Group Registration Statement, as of the MediaOne Group Effective
Date, and the Final MediaOne Group Prospectus (other than the financial
statements and other financial, accounting and operating (as described 


                                            16
<PAGE>


below) information contained therein, the AirTouch Furnished Information, and 
exhibit 25 to the MediaOne Group Registration Statement, as to which such 
counsel need express no opinion) did not comply as to form in all material 
respects with the applicable requirements of the Act, the Exchange Act and 
the Trust Indenture Act and the respective rules thereunder; and such counsel 
has no reason to believe that at the Effective Date the MediaOne Group 
Registration Statement (other than the financial statements and schedules and 
other financial, accounting and operating (as described below) information 
included therein and exhibit 25 to the MediaOne Group Registration Statement) 
contained any untrue statement of a material fact or omitted to state any 
material fact required to be stated therein or necessary to make the 
statements included therein not misleading or that, as of the date thereof or 
on the Closing Date, the Final MediaOne Group Prospectus (other than the 
financial statements and schedules and other financial, accounting and 
operating (as described below) information included therein, the AirTouch 
Furnished Information, and exhibit 25 to the MediaOne Group Registration 
Statement) included or includes any untrue statement of a material fact or 
omitted or omits to state a material fact required to be stated therein or 
necessary to make the statements included therein, in the light of the 
circumstances under which they were made, not misleading.  For purposes of 
this paragraph, the phrase "operating information" means information of the 
type included in the Final MediaOne Group Prospectus in the last item under 
the caption "Summary Financial Data."

     (d)  The Representatives shall have received from Cleary, Gottlieb, 
Steen & Hamilton, counsel for the Underwriters, such opinion or opinions, 
dated the Closing Date, with respect to the issuance and sale of the PIES, 
the Indenture, the MediaOne Group Registration Statement, the Final MediaOne 
Group Prospectus (together with any supplement thereto), the Shares, the 
AirTouch Registration Statement, the Final AirTouch Prospectus (together with 
any supplement thereto) and other related matters as the Representatives may 
reasonably require, and MediaOne Group and AirTouch shall have furnished to 
such counsel such documents as they request for the purpose of enabling them 
to pass upon such matters.

     (e)  AirTouch shall have furnished to the Representatives and to 
MediaOne Group the opinion of Margaret G. Gill, Esq., Senior Vice President, 
Legal, External Affairs and Secretary for AirTouch, dated as of the Closing 
Date, to the effect that:

           (i) each of AirTouch and the AirTouch Subsidiaries has been duly 
     incorporated and is validly existing as a corporation in good standing 
     under the laws of the jurisdiction in which it is organized with full 
     corporate power and authority to own, lease and operate its properties 
     and conduct its business as described in the Final AirTouch Prospectus 
     and, in the case of AirTouch, to enter into and perform this Agreement; 
     each of AirTouch and the AirTouch Subsidiaries is duly qualified to do 
     business as a foreign corporation and is in good standing under the laws 
     of each jurisdiction in which the character of the business conducted by 
     it or the location of the properties owned or leased by it makes such 
     qualification necessary, except where the failure to be so qualified or 
     in good standing would not have a Material Adverse Effect;

           (ii)     all of the outstanding shares of AirTouch Common Stock 
     have been duly authorized, validly issued, fully paid and nonassessable, 
     with no personal liability 


                                            17
<PAGE>

     attaching to the ownership thereof; except as described in the Final 
     AirTouch Prospectus, there are no preemptive rights, options, warrants 
     or other rights to subscribe for, to purchase or to convert any 
     obligations into or exchange any securities for, or any restriction upon 
     the voting or transfer of, any shares of capital stock of AirTouch 
     pursuant to the Amended and Restated Articles of Incorporation of 
     AirTouch, the Amended and Restated By-laws of AirTouch, or, to the 
     knowledge of such counsel, any agreement or other instrument to which 
     AirTouch is a party or by which it is bound; to the knowledge of such 
     counsel, neither the filing of the AirTouch Registration Statement nor 
     the offering or sale of the Shares pursuant to the PIES as contemplated 
     by this Agreement gives rise to any rights, other than those which have 
     been waived or satisfied, for or relating to the registration of any 
     shares of AirTouch Common Stock or other securities of AirTouch; and the 
     authorized, issued and outstanding capital stock of AirTouch at June 30, 
     1998 is as set forth under "Capitalization" in the Final AirTouch 
     Prospectus and the AirTouch Common Stock conforms to the description 
     thereof contained in the Final AirTouch Prospectus;

           (iii)    to the best knowledge of such counsel, there is no 
     franchise, contract or other document of a character required to be 
     described in the AirTouch Registration Statement or Final AirTouch 
     Prospectus, or to be filed as an exhibit thereto, which is not described 
     or filed as required; all descriptions in the Final AirTouch Prospectus 
     of statutes, regulations, legal or governmental proceedings, contracts 
     and other documents are accurate in all material respects and fairly 
     present the information required to be shown;

           (iv)     the AirTouch Registration Statement has become effective 
     under the Act; any required filing of the Final AirTouch Prospectus, and 
     any supplements thereto, pursuant to Rule 424(b) has been made in the 
     manner and within the time period required by Rule 424(b); to the 
     knowledge of such counsel, no stop order suspending the effectiveness of 
     the AirTouch Registration Statement has been issued, and no proceedings 
     for that purpose have been instituted or threatened;

           (v) the AirTouch Registration Statement and the Final AirTouch 
     Prospectus (except the financial statements and schedules and other 
     financial data contained therein, as to which such counsel need express 
     no opinion) comply as to form in all material respects with the 
     requirements of the Act and the rules and regulations thereunder;

           (vi)     this Agreement has been duly authorized, executed and 
     delivered by AirTouch; the execution and delivery of this Agreement by 
     AirTouch and the consummation by AirTouch of the transactions 
     contemplated hereby will not conflict with, result in a breach or 
     violation of, or constitute a default under (a) the Amended and Restated 
     Articles of Incorporation of AirTouch, the Amended and Restated By-laws 
     of AirTouch or any of the AirTouch Subsidiaries or (b) any material 
     agreement, indenture or other instrument to which any of them is a party 
     or by which any of them is bound filed as an exhibit to the AirTouch 
     Registration Statement or otherwise known to such counsel (except, in 
     the case of clause (a), for such conflicts, breaches, violations and 
     defaults that would not result in a Material Adverse Effect), or, to the 
     knowledge of such counsel, any 


                                            18
<PAGE>

     law, rule, administrative regulation or decree of any court, 
     governmental agency, regulatory body or other governmental body, or any 
     arbitrator having jurisdiction over AirTouch;

         (vii)  no consent, approval, authorization or order of any court, 
     governmental agency, regulatory body or other governmental body is 
     required for the performance of this Agreement by AirTouch or the 
     consummation by AirTouch of the transactions contemplated hereby, except 
     such as have been obtained under the Act;

           (viii)   to the knowledge of such counsel, there is no action, 
     suit or proceeding by or before any court or governmental agency, 
     regulatory body or other governmental body or any arbitrator involving 
     AirTouch required to be disclosed in the AirTouch Registration 
     Statement, other than those disclosed therein; and

           (ix)     the Shares are duly listed and admitted for trading on 
     the NYSE; the AirTouch Common Stock conforms in all material respects to 
     the description thereof contained in the Final AirTouch Prospectus.

     In addition such counsel shall state that although she is not passing
upon and has not checked the accuracy or completeness, or otherwise verified the
information furnished in the AirTouch Registration Statement and the Final
AirTouch Prospectus (except to the extent otherwise set forth above), she has
considered the information required to be furnished therein, and on the basis of
such consideration, but without independent checking and verification, she has
no reason to believe that, at the AirTouch Effective Date, the AirTouch
Registration Statement and the basic prospectus included therein at the AirTouch
Effective Date contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or the AirTouch Furnished Information
contained in the Final MediaOne Prospectus as of the date of such prospectus or
on the Closing Date contained or contains any untrue statement of a material
fact or omitted or omits to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading; it being understood that
with respect to the matters covered by this paragraph, counsel shall express no
opinion as to the financial statements and related schedules and other financial
or statistical data contained in or omitted from the AirTouch Registration
Statement or the AirTouch Furnished Information contained in the Final MediaOne
Prospectus.

     In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
California or the United States, to the extent she deems proper and specified in
such opinion, upon the opinion of other counsel of good standing whom such
counsel believes to be reliable and who are satisfactory to counsel for the
Underwriters and (B) as to matters of fact, to the extent such counsel deems
proper, on certificates of responsible officers of AirTouch and public
officials.  References to the Final AirTouch Prospectus in this paragraph (e)
include any supplements thereto at the Closing Date.

     (f)  MediaOne Group shall have furnished to the Representatives a
certificate of MediaOne Group, signed by the Executive Vice President and Chief
Financial Officer of 


                                            19

carefully examined the MediaOne Group Registration Statement, the Final 
MediaOne Group Prospectus, any supplements to the Final MediaOne Group 
Prospectus and this Agreement and that to the best of his knowledge after 
reasonable investigation:

           (i) the representations and warranties of MediaOne Group in this 
     Agreement are true and correct in all material respects on and as of the 
     Closing Date with the same effect as if made on the Closing Date and 
     MediaOne Group has complied with all the agreements and satisfied all 
     the conditions on its part to be performed or satisfied at or prior to 
     the Closing Date;

           (ii)     no stop order suspending the effectiveness of the 
     MediaOne Group Registration Statement has been issued and no proceedings 
     for that purpose have been instituted or, to MediaOne Group's knowledge, 
     threatened; and

           (iii)    since the date of the most recent financial statements 
     included in the Final MediaOne Group Prospectus (exclusive of any 
     supplement thereto), there has been no material adverse change in the 
     financial position or results of operations of MediaOne Group and its 
     subsidiaries taken as a whole, whether or not arising from transactions 
     in the ordinary course of business, except as set forth in or 
     contemplated in the Final MediaOne Group Prospectus (exclusive of any 
     supplement thereto).

     (g)  AirTouch shall have furnished to the Representatives a
certificate of AirTouch, signed by one of:  the Chairman of the Board, the Chief
Executive Officer, the President, any Vice Chairman, or any Vice President, and
one of:  the Chief Financial Officer, the Treasurer or any Assistant Treasurer

           (i) the representations and warranties of AirTouch in this 
     Agreement are true and correct in all material respects on and as of the 
     Closing Date with the same effect as if made on the Closing Date and

     conditions on its part to be performed or satisfied at or prior to the 
     Closing Date;

           (ii)     no stop order suspending the effectiveness of the 
     AirTouch Registration Statement has been issued and no proceedings for 
     that purpose have been instituted and are pending or, to his or her

           (iii)    since the date of the most recent financial statements 
     included in the Final AirTouch Prospectus (exclusive of any supplement 
     thereto), there has been no material adverse change or any development 
     involving a prospective material adverse change in the Financial 
     condition or results of operations of AirTouch and its subsidiaries 
     taken as a whole, whether or not arising from transactions in the 
     ordinary course of business, except as set forth in or contemplated by 
     the Final AirTouch Prospectus (exclusive of any 

                                            20

     supplement thereto).

     (i)  At the Execution Time and at the Closing Date, Arthur Andersen
LLP, accountants for MediaOne Group for the years ended December 31, 1996 and
1997, shall have furnished to the Representatives a letter or letters, dated
respectively as of the Execution Time and as of the Closing Date, in form and
substance satisfactory to the Representatives, confirming that they are
independent accountants within the meaning of the Act and the Exchange Act and
the respective applicable published rules and regulations thereunder and stating
in effect that:

          (1)  in their opinion the audited financial statements and 
     financial statement schedules included or incorporated in the MediaOne 
     Group Registration Statement and the Final MediaOne Group Prospectus and 
     reported on by them comply in form in all material respects with the 
     applicable accounting requirements of the Act and the Exchange Act and 
     the related published rules and regulations;

          (2)  on the basis of a reading of the latest unaudited financial 
     statements made available by the MediaOne Group and its subsidiaries; 
     carrying out certain specified procedures (but not an examination in 
     accordance with generally accepted auditing standards) which would not 
     necessarily reveal matters of significance with respect to the comments 
     set forth in such letter; a reading of the minutes of the meetings of 
     the shareholders, directors and executive, finance, audit committees of 
     MediaOne Group and its subsidiaries; and inquiries of certain officials 
     of MediaOne Group who have responsibility for financial and accounting 
     matters of MediaOne Group and its subsidiaries as to transactions and 
     events subsequent to December 31, 1997, nothing came to their attention 
     which caused them to believe that:

               (a)  any unaudited financial statements included or 
          incorporated in the MediaOne Group Registration Statement and the 
          Final MediaOne Group Prospectus do not comply in form in all 
          material respects with applicable accounting requirements and with 
          the published rules and regulations of the Commission with respect 
          to financial statements included or incorporated in quarterly 
          reports on Form 10-Q under the Exchange Act; or said unaudited 
          financial statements are not in conformity with generally accepted 
          accounting principles applied on a basis substantially consistent 
          with that of the audited financial statements included or 
          incorporated in the MediaOne Group Registration Statement and the 
          Final MediaOne Group Prospectus; or

               (b)    with respect to the period subsequent to June 30, 1998, 
          there were any changes, at a specified date not more than five 
          business days prior to the date of the letter, in the capital stock 
          of MediaOne Group, or any increase in the consolidated long-term 
          debt of MediaOne Group and its subsidiaries, or decreases in 
          consolidated net current assets or net assets as compared with the 
          amounts shown on the June 30, 1998 consolidated balance sheet 
          included or 

                                            21

          incorporated in the MediaOne Group Registration Statement and the 
          Final MediaOne Group Prospectus, or for the period from July 1, 
          1998 to such specified date there were any decreases, as compared 
          with the corresponding period in the preceding year in consolidated 
          revenues, net income or net income per share of MediaOne Group and 
          its subsidiaries, except in all instances for changes or decreases 
          set forth in such letter, in which case the letter shall be 
          accompanied by an explanation by MediaOne Group as to the 
          significance thereof unless said explanation is not deemed 
          necessary by the Representatives;

               (c)  they have performed certain other specified procedures as 
          a result of which they determined that certain information of an 
          accounting, financial or statistical nature (which is limited to 
          accounting, financial or statistical information derived from the 
          general accounting records of MediaOne Group and its subsidiaries) 
          set forth or incorporated in the MediaOne Group Registration 
          Statement and the Final MediaOne Group Prospectus and in Exhibit 12 
          to the MediaOne Group Registration Statement, agrees with the 
          accounting records of MediaOne Group and its subsidiaries, 
          excluding any questions of legal interpretation.

     (ii)  At the Execution Time and at the Closing Date, 
PricewaterhouseCoopers LLP, accountants for MediaOne Group for the year ended 
December 31, 1995, shall have furnished to the Representatives a letter or 
letters, dated respectively as of the Execution Time and as of the Closing 
Date, in form and substance satisfactory to the Representatives, confirming 
that they are independent accountants within the meaning of the Act and the 
Exchange Act and the respective applicable published rules and regulations 
thereunder and stating in effect that:

          (1)  in their opinion the audited financial statements and 
     financial statement schedules included or incorporated in the MediaOne 
     Group Registration Statement and the Final MediaOne Group Prospectus and 
     reported on by them comply in form in all material respects with the 
     applicable accounting requirements of the Act and the Exchange Act and 
     the related published rules and regulations;

          (2)  they have performed certain other specified procedures as a 
     result of which they determined that certain information of an 
     accounting, financial or statistical nature (which is limited to 
     accounting, financial or statistical information derived from the 
     general accounting records of MediaOne Group and its subsidiaries) 
     specified by the Representatives set forth or incorporated in the 
     MediaOne Group Registration Statement and the Final MediaOne Group 
     Prospectus, agrees with the accounting records of MediaOne Group and its 
     subsidiaries, excluding any questions of legal interpretation.

References to the Final MediaOne Group Prospectus in this paragraph (h) include
any supplement thereto at the date of the letter.

          10-Q under the Exchange Act; or said unaudited financial statements 
          are not in conformity with generally accepted accounting principles 
          applied on a basis substantially consistent with that of the 
          audited financial statements included or incorporated in the 
          AirTouch Registration Statement and the Final AirTouch Prospectus; 
          or

               (2)  with respect to the period subsequent to June 30, 1998, 
          there were any increases, at a specified date not more than five 
          business days prior to the date of the letter, in borrowings under 
          the commercial paper program of AirTouch and its consolidated 
          subsidiaries as compared with the amounts shown on the June 30, 
          1998 consolidated balance sheet included or incorporated in the 
          AirTouch Registration Statement and the Final AirTouch Prospectus, 
          or for the period from July 1, 1998 to such specified date there 
          were any decreases, as compared with the corresponding period in 
          the preceding year, in consolidated operating revenues, except in 
          all instances for changes or decreases set forth in such letter, in 
          which case the letter shall be accompanied by an explanation by 
          AirTouch as to the significance thereof unless said explanation is 
          not deemed necessary

          by the Representative.

           (iii)    they have performed certain other specified procedures as 
     a result of which they determined that certain information of an 
     accounting, financial or statistical nature (which is limited to 
     accounting, financial or statistical information derived from the 
     general accounting records of AirTouch and its subsidiaries) set forth 
     or incorporated in the AirTouch Registration Statement and the Final 
     AirTouch Prospectus, agrees with the accounting records of AirTouch and 
     its subsidiaries, excluding any questions of legal interpretation.

References to the Final AirTouch Prospectus in this paragraph (i) include any
supplement thereto at the date of the letter.

     (j)  At the Execution Time and at the Closing Date, Arthur Andersen
LLP, accountants for the former US WEST NewVector Group, Inc., shall have
furnished to the Representatives a letter or letters related to US WEST
NewVector Group, Inc., dated respectively as of the Execution Time and as of the
Closing Date, in form and substance satisfactory to the Representatives.

     (k)  Subsequent to the Execution Time or, if earlier, the dates as of
which information is given in each of the MediaOne Group Registration Statement
and the AirTouch Registration Statements (exclusive of any amendment thereof)
and each of the Final MediaOne Group Prospectus and the Final AirTouch
Prospectus (exclusive of any supplement thereto), there shall not have been any
change, or any development involving a prospective change, in or affecting the
business or properties of either MediaOne Group or AirTouch and their respective
subsidiaries, taken as a whole, the effect of which is, in the judgment of the
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the PIES as contemplated
by the MediaOne Group Registration Statement (exclusive of any amendment
thereof) and the Final MediaOne Group Prospectus (exclusive of any supplement
thereto).

     (l)  Subsequent to the Execution Time, there shall not have been any
decrease in the rating of any of MediaOne Group's or AirTouch's debt securities
by any "nationally recognized statistical rating organization" (as defined for
purposes of Rule 436(g) under the Act) or any notice given of any intended or
potential decrease in any such rating or of a possible change in any such rating
that does not indicate the direction of the possible change.

     (m)  The PIES shall have been listed and admitted and authorized for
trading on the New York Stock Exchange, and satisfactory evidence of such
actions shall have been provided to the Representatives.

     (n)  Prior to the Closing Date, each of MediaOne Group and AirTouch
shall have furnished to the Representatives such further information,
certificates and documents as the Representatives may reasonably request.

     If any of the conditions specified in this Section 8 shall not have
been fulfilled in 


                                            24
<PAGE>

all material respects when and as provided in this Agreement, or if any of 
the opinions and certificates mentioned above or elsewhere in this Agreement 
shall not be in all material respects reasonably satisfactory in form and 
substance to the Representatives and counsel for the Underwriters, this 
Agreement and all obligations of the Underwriters hereunder may be canceled 
at, or at any time prior to, the Closing Date by the Representatives.  Notice 
of such cancellation shall be given to MediaOne Group and AirTouch in writing 
or by telephone or telegraph confirmed in writing.

     9.   REIMBURSEMENT OF UNDERWRITERS' EXPENSES.  If the sale of the PIES
provided for herein is not consummated because any condition to the obligations
of the Underwriters set forth in Section 8 hereof is not satisfied, because of
any termination pursuant to Section 12 hereof or because of any refusal,
inability or failure on the part of MediaOne Group or AirTouch to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, MediaOne Group will reimburse the
Underwriters severally upon demand for all reasonable out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the PIES. 
The Underwriters agree to pay such expenses, fees and disbursements in any other
event.  In no event will MediaOne Group be liable to any of the Underwriters for
damages on account of loss of anticipated profits.

     10.  INDEMNIFICATION AND CONTRIBUTION.  (a) MediaOne Group agrees to
indemnify and hold harmless each Underwriter and AirTouch, the directors,
officers, employees and agents of each Underwriter or AirTouch, and each person
who controls any Underwriter or AirTouch within the meaning of either the Act or
the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject under the Act,
the Exchange Act or other Federal or state statutory law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
MediaOne Group Registration Statement as originally filed or in any amendment
thereof, or in the Basic MediaOne Group Prospectus, any Preliminary Final
MediaOne Group Prospectus or the Final MediaOne Group Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER,
that MediaOne Group will not be liable under the indemnity agreement in this
paragraph (a) to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made in the MediaOne Group
Registration Statement as originally filed or in any amendment thereof, or in
the Basic MediaOne Group Prospectus, any Preliminary Final MediaOne Group
Prospectus or the Final MediaOne Group Prospectus, or in any amendment thereof
or supplement thereto in reliance upon and in conformity with (A) written
information furnished to MediaOne Group by or on behalf of any Underwriter
through the Representatives specifically for inclusion therein or (B) the
AirTouch Furnished Information (including the information contained in any
Preliminary Final AirTouch 


                                       25
<PAGE>

Prospectus or Final AirTouch Prospectus included in any such document (other 
than information contained in or omitted from any such Preliminary Final 
AirTouch Prospectus or Final AirTouch Prospectus in reliance on and 
conformity with MediaOne Group Furnished Information)); and PROVIDED, FURTHER 
that MediaOne Group shall not be liable to any Underwriter under the 
indemnity agreement in this paragraph (a) with respect to the Preliminary 
Final MediaOne Group Prospectus to the extent that any such loss, claim, 
damage or liability of such Underwriter results from the fact that such 
Underwriter sold PIES to a person as to whom it shall be established that 
there was not sent or given, at or prior to the written confirmation of such 
sale, a copy of the Final MediaOne Group Prospectus (excluding documents 
incorporated by reference), as the case may be, or of the Final MediaOne 
Group Prospectus as then amended or supplemented (excluding documents 
incorporated by reference) in any case where such delivery is required by the 
Act and where MediaOne Group has previously furnished copies thereof in 
sufficient quantity to such Underwriter and the loss, claim, damage or 
liability of such Underwriter results from an untrue statement or omission of 
a material fact contained in the Final Preliminary MediaOne Group Prospectus 
and corrected in the Final MediaOne Group Prospectus (excluding documents 
incorporated by reference) or in the Final MediaOne Group Prospectus as then 
amended or supplemented (excluding documents incorporated by reference).  
This indemnity agreement will be in addition to any liability which MediaOne 
Group may otherwise have.

    (b)  AirTouch agrees to indemnify and hold harmless each Underwriter, the 
directors, officers, employees and agents of each Underwriter, and each 
person who controls any Underwriter within the meaning of either the Act or 
the Exchange Act, and AirTouch agrees to indemnify and hold harmless MediaOne 
Group, the directors, officers, employees and agents of MediaOne Group, and 
each person who controls MediaOne Group within the meaning of either the Act 
or the Exchange Act, in either case, against any and all losses, claims, 
damages or liabilities, joint or several, to which they or any of them may 
become subject under the Act, the Exchange Act or other Federal or state 
statutory law or regulation, at common law or otherwise, insofar as such 
losses, claims, damages or liabilities (or actions in respect thereof) arise 
out of or are based upon any untrue statement or alleged untrue statement of 
a material fact contained in (i) the AirTouch Registration Statement as 
originally filed or in any amendment thereof, or in any Preliminary Final 
AirTouch Prospectus or the Final AirTouch Prospectus, or in any amendment 
thereof or supplement thereto, or (ii) all other AirTouch Furnished 
Information, or arise out of or are based upon the omission hereto, or arise 
out of or are based upon the omission or alleged omission to state in the 
documents referred to in clause (i) or (ii) above a material fact required to 
be stated in the documents referred to in clause (i) or (ii) above or 
necessary to make the statements therein not misleading, and agrees to 
reimburse each such indemnified party, as incurred, for any legal or other 
expenses reasonably incurred by them in connection with investigating or 
defending any such loss, claim, damage, liability or action; PROVIDED, 
HOWEVER, that AirTouch will not be liable under the indemnity agreement in 
this paragraph (b) to the extent that any such loss, claim, damage or 
liability arises out of or is based upon any such untrue statement or alleged 
untrue statement or omission or alleged omission made in the documents 
referred to in clause (i) above in reliance upon and in conformity with (A) 
written information furnished to AirTouch by or on behalf of any Underwriter 
through the Representatives specifically for inclusion therein or (B) 
MediaOne Group Furnished Information; and PROVIDED, 

                                       26
<PAGE>

FURTHER that AirTouch shall not be liable to any Underwriter under the 
indemnity agreement in this paragraph (b) with respect to the Preliminary 
Final AirTouch Prospectus or Final MediaOne Group Prospectus to the extent 
that any such loss, claim, damage or liability of such Underwriter results 
from the fact that such Underwriter sold PIES to a person as to whom it shall 
be established that there was not sent or given, at or prior to the written 
confirmation of such sale, a copy of the Final MediaOne Group Prospectus 
(including the Final AirTouch Prospectus, but excluding, in either case, 
documents incorporated by reference)) or of the Final MediaOne Group 
Prospectus (including the Final AirTouch Prospectus as then amended or 
supplemented (excluding, in either case, documents incorporated by 
reference)), as the case may be, in any case where such delivery is required 
by the Act and, if the correction were made in the Final AirTouch Prospectus 
(or amendment or supplement thereto), AirTouch has previously furnished 
copies of the Final AirTouch Prospectus (excluding documents incorporated by 
reference) or the Final AirTouch Prospectus as then amended or supplemented 
(excluding documents incorporated by reference) in sufficient quantity to 
such Underwriter and the loss, claim, damage or liability of such Underwriter 
results from an untrue statement or omission of a material fact contained in 
the Preliminary Final AirTouch Prospectus and corrected in the Final AirTouch 
Prospectus (excluding documents incorporated by reference) or in the Final 
AirTouch Prospectus as then amended or supplemented (excluding documents 
incorporated by reference).  This indemnity agreement will be in addition to 
any liability which AirTouch may otherwise have.

     (c)  Each Underwriter severally agrees to indemnify and hold harmless
MediaOne Group and AirTouch, each of their respective directors, each of their
respective officers who signs the MediaOne Group Registration Statement, and
each person who controls MediaOne Group or AirTouch within the meaning of either
the Act or the Exchange Act, to the same extent as the foregoing indemnity in
paragraph (a) from MediaOne Group to each Underwriter and AirTouch, but only
with reference to written information furnished to MediaOne Group by or on
behalf of such Underwriter through the Representatives specifically for
inclusion in the documents referred to in the foregoing indemnity.  This
indemnity agreement will be in addition to any liability which any Underwriter
may otherwise have.  MediaOne Group and AirTouch acknowledge that the statements
set forth in the last paragraph of the cover page, in the last paragraph of the
inside cover page and under the heading "Plan of Distribution" in any
Preliminary Final MediaOne Group Prospectus or the Final MediaOne Group
Prospectus constitute the only information furnished in writing by or on behalf
of the several Underwriters as of the date hereof for inclusion in the documents
referred to in the foregoing indemnity, and you, as the Representative, confirm
that such statements are correct.

     (d)  Each Underwriter severally agrees to indemnify and hold harmless
AirTouch and MediaOne Group, each of their respective directors, each of their
respective officers who signs the AirTouch Registration Statement and each
person who controls AirTouch or MediaOne Group within the meaning of either the
Act or the Exchange Act, to the same extent as the foregoing indemnity in
paragraph (b) from AirTouch to each Underwriter and MediaOne Group, but only
with reference to written information relating to such Underwriter furnished to
AirTouch or MediaOne Group by or on behalf of such Underwriter through the
Representatives specifically for inclusion in the documents referred to in
clause (i) of the foregoing indemnity.  This indemnity agreement will be in
addition to any liability which any Underwriter may 


                                       27
<PAGE>

otherwise have.  AirTouch and MediaOne Group acknowledge that the statements 
set forth in the first paragraph of the inside cover page and under the 
heading "Plan of Distribution" in any Preliminary Final AirTouch Prospectus 
or the Final AirTouch Prospectus constitute the only information furnished in 
writing by or on behalf of the several Underwriters as of the date hereof for 
inclusion in the documents referred to in the foregoing indemnity, and you, 
as the Representatives, confirm that such statements are correct.

     Promptly after receipt by an indemnified party under this Section 10
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 10, notify the indemnifying party in writing of the commencement
thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from any liability under paragraphs (a), (b), (c) or (d) above except
to the extent it has been materially prejudiced by such omission and (ii) will
not, in any event, relieve the indemnifying party from any obligations to any
indemnified party other than the indemnification obligation provided in
paragraphs (a), (b), (c) or (d) above.  In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel
satisfactory to such indemnified party; PROVIDED, HOWEVER, that, any indemnified
party may employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of such indemnified party except as provided below.  Upon receipt of
notice from the indemnifying party to the indemnified party of its election to
assume the defense thereof and approval by the indemnified party of counsel, the
indemnifying party will not be liable to such indemnified party (except as set
forth below) under this Section 10 for any legal or other expenses subsequently
incurred by such indemnified party in connection with the defense thereof unless
(i) the indemnified party shall have employed separate counsel in connection
with the assertion of legal defenses which the indemnified party shall have been
advised by such counsel may be available to it and/or other indemnified parties
which are different from or additional to those available to the indemnifying
party (it being understood, however, that the indemnifying party shall not be
liable for the expenses of more than one separate counsel, approved by the
representatives representing the indemnified parties who are parties to such
action), (ii) the indemnifying party shall not have employed satisfactory
counsel to the indemnified party to represent the indemnified party within a
reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; and except that, if clause (i)
or (iii) is applicable, such liability shall be only in respect of the counsel
referred to in such clause (i) or (iii).  An indemnifying party shall not be
liable for any amounts paid in settlement of any action or claim without its
written consent of the indemnifying party, which shall not be unreasonably
withheld.  An indemnifying party will not, without the prior written consent of
each indemnified party, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of such indemnified party from all liability
arising out of such claim, action, suit or proceeding.


                                       28
<PAGE>

     (f)  In the event that the indemnity provided in paragraph (a), (b),
(c) or (d) of this Section 10 is for any reason held by a court to be
unavailable to an indemnified party for any reason, MediaOne Group, AirTouch and
the Underwriters agree to contribute to the aggregate losses, claims, damages
and liabilities (including legal or other expenses reasonably incurred in
connection with investigating or defending same) (collectively "Losses") to
which MediaOne Group, AirTouch and one or more of the Underwriters may be
subject (i) if the claim under such indemnity would have related to the
Underwriters as an indemnifying or indemnified party, (x) in such proportion as
shall be appropriate to reflect the relative benefits received by MediaOne Group
or AirTouch, as applicable, on the one hand and the Underwriters, on the other,
from the offering of the PIES or (y) if the allocation provided by clause (i)
(x) above is not permitted by applicable law or if the otherwise indemnified
party failed to give the notice required under Section 10(e), in such proportion
as is appropriate to reflect not only the relative benefits referred to in
clause (i) (x) above but also the relative fault of MediaOne Group or AirTouch,
as applicable, on the one hand and the Underwriters, on the other, with respect
to the statements or omissions which resulted in such Losses, as well as any
other relevant equitable considerations or (ii) if the claim under the indemnity
would have related to MediaOne Group or AirTouch as the respective indemnifying
and indemnified parties (or vice versa), in such proportion as shall be
appropriate to reflect the relative fault of MediaOne Group or AirTouch, as
applicable with respect to the statements or omissions which resulted in such
Losses as well as any other relevant equitable principles; PROVIDED, HOWEVER,
that in no case shall any Underwriter (except as may be provided in any
agreement among underwriters relating to the offering of the PIES) be
responsible for any amount in excess of the product of (i) the total Losses and
(ii) the percentage (expressed as a decimal) that the aggregate underwriting
discount applicable to the PIES purchased by such Underwriter hereunder bears to
the aggregate initial public offering price of such PIES.  The relative benefits
received by MediaOne Group or AirTouch, as applicable, on the one hand and the
Underwriters on the other with respect to such offering shall be deemed to be
equal to the total net proceeds from the offering (before deducting expenses)
received by MediaOne Group, and the total underwriting discounts and
commissions, respectively, in each case as set forth on the cover page of the
Final MediaOne Group Prospectus and, as between AirTouch and the Underwriters,
AirTouch shall be deemed for this purpose to have received such total net
proceeds as received by MediaOne Group.  Relative fault shall be determined by
reference to whether any alleged untrue statement or omission relates to
information provided by MediaOne Group or AirTouch, as applicable, on the one
hand or the Underwriters on the other, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission.  MediaOne Group, AirTouch and the Underwriters agree
that it would not be just and equitable if contribution were determined by PRO
RATA allocation or any other method of allocation which does not take account of
the equitable considerations referred to above.  Notwithstanding the provisions
of this paragraph (g), no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  For
purposes of this Section 10, each person who controls an Underwriter within the
meaning of either the Act or the Exchange Act and each director, officer,
employee and agent of an Underwriter shall have the same rights to contribution
as such Underwriter, and each person who controls MediaOne Group or AirTouch
within the meaning of either the Act or the Exchange Act, each officer of
MediaOne Group or AirTouch who shall have signed the MediaOne Group 


                                       29
<PAGE>

Registration Statement or the AirTouch Registration Statement, as the case 
may be, and each director of MediaOne Group or AirTouch shall have the same 
rights to contribution as MediaOne Group or AirTouch, subject in each case to 
the applicable terms and conditions of this paragraph (g).  Any party 
entitled to contribution will, promptly after receipt of notice of 
commencement of any action, suit or proceeding against another party or 
parties under this paragraph (g), notify such party or parties from whom 
contribution may be sought, but the omission to so notify in writing such 
party or parties shall not relieve the party or parties from whom 
contribution may be sought from any other obligation it or they may have 
hereunder or otherwise under this paragraph (g).

     11.  DEFAULT BY AN UNDERWRITER.  If any one or more Underwriters shall
fail to purchase and pay for any of the PIES agreed to be purchased by such
Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of PIES
set forth opposite their names in Schedule I hereto bears to the aggregate
principal amount of PIES set forth opposite the names of all the remaining
Underwriters) the PIES which the defaulting Underwriter or Underwriters agreed
but failed to purchase; PROVIDED, HOWEVER, that in the event that the aggregate
principal amount of PIES which the defaulting Underwriter or Underwriters agreed
but failed to purchase shall exceed 10% of the aggregate amount of PIES set
forth in Schedule I hereto, the remaining Underwriters shall have the right to
purchase all, but shall not be under any obligation to purchase any, of the
PIES, and if such nondefaulting Underwriters do not purchase all the PIES, this
Agreement will terminate without liability to any nondefaulting Underwriter,
MediaOne Group or AirTouch.  In the event of a default by any Underwriter as set
forth in this Section 11, the Closing Date shall be postponed for such period,
not exceeding seven days, as the Representatives shall determine in order that
the required changes in the MediaOne Group or AirTouch Registration Statement
and the Final MediaOne Group or Final AirTouch Prospectus or in any other
documents or arrangements may be effected.  Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to MediaOne
Group, AirTouch and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

     12.  TERMINATION.  This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by written notice given to
MediaOne Group and AirTouch prior to delivery of and payment for the PIES, if
prior to such time (i) trading in MediaOne Group's or AirTouch's common stock
shall have been suspended by the Commission or trading in securities generally
on the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared by either Federal or New York State authorities or
(iii) there shall have occurred any outbreak or escalation of hostilities,
declaration by the United States of a national emergency or war or other
calamity or crisis, the effect of which on financial markets of the United
States is such as to make it, in the judgment of the Representatives,
impracticable or inadvisable to proceed with the offering or delivery of the
PIES as contemplated by the Final MediaOne Group Prospectus (exclusive of any
supplement thereto).

Common Stock otherwise deliverable at Maturity (the "Cash Delivery Option").  
The amount of cash deliverable in respect of each PIES (calculated to the 
nearest 1/100th of a dollar per PIES or, if there is not a nearest 1/100th of 
a dollar, then to the next higher 1/100th of a dollar) shall be equal to the 
product of the number of shares of AirTouch Common Stock otherwise 
deliverable in respect of such PIES on the date of Maturity multiplied by the 
Maturity Price.  An election to exercise the Cash Delivery Option with 
respect to less than all of the shares of AirTouch Common Stock otherwise 
deliverable at Maturity shall not in any way limit the Company's obligation 
to deliver the remaining shares of AirTouch Common Stock deliverable at 
Maturity.  As further provided in Section 203, no fractional shares of 
AirTouch Common Stock shall be delivered pursuant to this Section 202.  In 
determining the amount of cash deliverable in exchange for the PIES in lieu 
of shares of AirTouch Common Stock pursuant to the fourth sentence of this 
Section 202, if more than one PIES shall be surrendered for exchange at one 
time by the same Holder, the amount of cash which shall be delivered upon 
exchange shall be computed on the basis of the aggregate number of PIES so 
surrendered at Maturity.

          SECTION 203.  NO FRACTIONAL SHARES. 

          If more than one PIES shall be surrendered for exchange pursuant to
Section 202 at one time by the same Holder, the number of full shares of
AirTouch Common Stock which shall be delivered upon such exchange, in whole or
in part, as the case may be, shall be computed on the basis of the aggregate
number of PIES surrendered.  No fractional shares or scrip representing
fractional shares of AirTouch Common Stock shall be issued or delivered upon any
exchange pursuant to Section 202 of any PIES.  In lieu of any fractional share
of AirTouch Common Stock which, but for the immediately preceding sentence,
would otherwise be deliverable upon such exchange, the Company, through any
applicable Paying Agent, shall make a cash payment in respect of such fractional
interest in an amount equal to the value of such fractional shares at the
Maturity Price.  The Company shall, upon such exchange of any PIES, provide cash
to any applicable Paying Agent in an amount equal to the cash payable with
respect to any fractional shares of AirTouch Common Stock deliverable upon such
exchange, and the Company shall retain such fractional shares of AirTouch Common
Stock.

          SECTION 204.  EXTENSIONS AND POST-EXTENSION TERMINATION.

          The Company may at its option elect to extend the Stated Maturity of
the PIES to November [__], 2001 and may further elect to extend the maturity of
the PIES to February [__], 2002.  The period from and including August [+1],
2001 to the then current Stated Maturity, is referred to herein as an "Extension
Period."  The Company may exercise the election to extend the Stated Maturity by
giving notice as provided in Section 206(d).  In the event that the Company
exercises its option to extend the 


                                       9
<PAGE>

maturity of the PIES to February __, 2002, interest at the rate set forth in 
Section 201 will continue to accrue on the PIES until Maturity and additional 
interest will accrue in arrears, commencing November [__], 2001 until 
Maturity, at a rate per annum equal to 0.5% of the principal amount of the 
PIES.  Such additional interest shall be payable in the same manner, at the 
same time and to the same Holders as other interest payments required to be 
made under the PIES.

          The Company may elect to cause all but not less than all of the 
PIES to mature at any time within an Extension Period upon completion of a 
Refinancing Offer ("Post-Extension Termination"), whereupon the PIES shall 
terminate and be repaid.  The Company may exercise this election by (i) 
providing to the Trustee an Officers' Certificate to the effect that MediaOne 
is engaged in good faith efforts to launch and consummate a Refinancing Offer 
and (ii) giving notice as provided in Section 206(e).  The related date of 
Maturity for the PIES shall be the anticipated settlement date indicated in 
such notice, except that if the Company postpones the settlement date for the 
Refinancing Offer and gives two Business Days' prior notice by press release 
to Holders of such postponement, the date of Maturity for the PIES shall be 
such postponed date on which the Refinancing Offer actually settles.  
Notwithstanding the foregoing, if the Company terminates or abandons a 
Refinancing Offer and gives notice thereof by press release to Holders, any 
election made to cause Post-Extension Termination of the PIES will be deemed 
rescinded and thereafter the PIES will mature on the then existing date of 
Stated Maturity, subject to Post-Extension Termination on the terms described 
herein.

          SECTION 205.  ADJUSTMENT OF EXCHANGE RATE.

          (a)  ADJUSTMENT FOR DISTRIBUTIONS, CERTAIN RECLASSIFICATIONS, ETC. 
The Exchange Rate shall be subject to adjustment from time to time as follows: 

          (i) If AirTouch shall:

               (A)  pay a stock dividend or make a distribution, in either case,
          with respect to the AirTouch Common Stock in shares of such stock;

               (B)  subdivide or split its outstanding shares of AirTouch Common
          Stock; 

               (C)  combine its outstanding shares of AirTouch Common Stock into
          a smaller number of shares; or

               (D)  issue by reclassification (other than a reclassification
          pursuant to clause (ii), (iii), (iv) or (v) of the definition of
          Adjustment Event in paragraph (b) of this Section) of its shares of
          AirTouch Common Stock any other shares of common stock of AirTouch
          (other than shares of a class of common stock of 


                                       10
<PAGE>

          AirTouch that is intended to reflect separately less than all of the 
          businesses of AirTouch and its subsidiaries);

     then, in any such event, the Exchange Rate shall be adjusted by adjusting
     each of the Share Components of the Exchange Rate in effect immediately
     prior to such event so that a Holder of any PIES shall be entitled to
     receive, upon mandatory exchange pursuant to Section 202 of the principal
     amount of such PIES at Maturity, the number of shares of AirTouch Common
     Stock (or, in the case of a reclassification referred to in clause (D) of
     this sentence, the number of shares of other common stock of AirTouch
     issued pursuant thereto) which such Holder of such PIES would have owned or
     been entitled to receive immediately following such event had such PIES
     been exchanged immediately prior to such event or any record date with
     respect thereto.  Each such adjustment shall become effective at the
     opening of business on the Business Day next following the record date for
     determination of holders of AirTouch Common Stock entitled to receive such
     dividend or distribution in the case of a dividend or distribution and
     shall become effective immediately after the effective date in the case of
     a subdivision, split, combination or reclassification.  Each such
     adjustment shall be made successively.

         (ii) If AirTouch shall, after the date hereof, issue rights or warrants
     (other than rights to purchase AirTouch Common Stock pursuant to a plan for
     the reinvestment of dividends or interest) to all holders of AirTouch
     Common Stock entitling them to subscribe for or purchase shares of AirTouch
     Common Stock at a price per share less than the Market Price of the
     AirTouch Common Stock on the Business Day next following the record date
     for the determination of holders of AirTouch Common Stock entitled to
     receive such rights or warrants, then in each case the Exchange Rate shall
     be adjusted by multiplying each of the Share Components of the Exchange
     Rate in effect on the record date for the issuance of such rights or
     warrants, by a fraction, of which the numerator shall be (A) the number of
     shares of AirTouch Common Stock outstanding on the record date for the
     issuance of such rights or warrants, plus (B) the number of additional
     shares of AirTouch Common Stock offered for subscription or purchase
     pursuant to such rights or warrants, and of which the denominator shall be
     (X) the number of shares of AirTouch Common Stock outstanding on the record
     date for the issuance of such rights or warrants, plus (Y) the number
     specified in clause (B) above multiplied by the quotient of the exercise
     price of such rights or warrants divided by the Market Price of the
     AirTouch Common Stock on the Business Day next following the record date
     for the determination of holders of AirTouch Common Stock entitled to
     receive such rights or warrants.  Such adjustment shall become effective at
     the opening of business on the Business Day next following the record date
     for the determination of stockholders entitled to receive such rights or
     warrants.  To the extent that such rights or warrants expire prior to the
     Maturity of the PIES and shares of AirTouch Common Stock are not delivered
     pursuant to such rights or warrants prior to such expiration, the Exchange
     Rate shall be readjusted to the Exchange Rate which would then be in effect
     had such adjustments for the issuance of 


                                       11
<PAGE>

     such rights or warrants been made upon the basis of delivery of only the 
     number of shares of AirTouch Common Stock actually delivered pursuant to 
     such rights or warrants.  Each such adjustment shall be made successively.

          (iii) Any shares of AirTouch Common Stock issuable in payment of a
     dividend that has been declared but not yet issued shall be deemed to have
     been issued immediately prior to the close of business on the record date
     for such dividend for purposes of calculating the number of outstanding
     shares of AirTouch Common Stock under paragraph (a)(ii) of this Section.

         (iv) All adjustments to the Exchange Rate shall be calculated to the
     nearest 1/10,000th of a share of AirTouch Common Stock (or if there is not
     a nearest 1/10,000th of a share, to the next higher 1/10,000th of a share).
     No adjustment in the Exchange Rate shall be required unless such adjustment
     would require an increase or decrease of at least one percent therein;
     PROVIDED, HOWEVER, that any adjustments which by reason of this paragraph
     (a)(iv) are not required to be made shall be carried forward and taken into
     account in any subsequent adjustment.  If an adjustment is made to the
     Exchange Rate pursuant to paragraphs (a)(i) or (a)(ii) of this Section, an
     adjustment shall also be made to the Maturity Price as such term is used
     throughout the definition of Exchange Rate set forth in Section 101.  The
     required adjustment to the Maturity Price shall be made at Maturity by
     multiplying the Maturity Price by the cumulative number or fraction
     determined under paragraphs (a)(i) and/or (a)(ii) of this Section by which
     the original Exchange Rate was multiplied to adjust such rate.  In the case
     of the reclassification of any shares of AirTouch Common Stock into any
     shares of common stock of AirTouch other than AirTouch Common Stock, such
     shares of common stock shall be deemed shares of AirTouch Common Stock for
     all purposes.  Each such adjustment to the Exchange Rate and the Maturity
     Price shall be made successively.

          (b)  OTHER ADJUSTMENT EVENTS.  In the event of (i) any dividend or
distribution by AirTouch to all holders of AirTouch Common Stock of evidences of
its indebtedness or other assets (excluding any dividends or distributions
referred to in clause (A) of paragraph (a)(i) of this Section, any shares of
common stock issued pursuant to a reclassification referred to in clause (D) of
paragraph (a)(i) of this Section and any Ordinary Cash Dividends) or any
issuance by AirTouch to all holders of AirTouch Common Stock of rights or
warrants to subscribe for or purchase any of its securities (other than rights
or warrants referred to in paragraph (a)(ii) of this Section), (ii) any
consolidation or merger of AirTouch with or into another entity (other than a
merger or consolidation in which AirTouch is the continuing corporation and in
which the AirTouch Common Stock outstanding immediately prior to the merger or
consolidation is not exchanged for cash, securities or other property of
AirTouch or another corporation), (iii) any sale, transfer, lease or conveyance
to another corporation of the property of AirTouch as an entirety or
substantially as an entirety, (iv) any statutory exchange of securities of
AirTouch with another corporation (other than in connection with a merger or
acquisition) or (v) any liquidation, 


                                       12
<PAGE>

dissolution or winding up of AirTouch (any such event, an "Adjustment 
Event"), the property receivable by Holders of PIES at Maturity shall be 
subject to adjustment from time to time as follows:

               (1)  Each Holder of a PIES will receive at Maturity, in lieu of
     or (in the case of an Adjustment Event described in clause (i) of this
     paragraph (b)) in addition to, the shares of AirTouch Common Stock that it
     would otherwise receive as required by Section 202, cash in an amount equal
     to (A) if the Maturity Price is greater than or equal to the Threshold
     Appreciation Price, - multiplied by the Transaction Value, (B) if the
     Maturity Price is less than the Threshold Appreciation Price but is greater
     than the Initial Price, the product of (x) the Initial Price divided by the
     Maturity Price multiplied by (y) the Transaction Value and (C) if the
     Maturity Price is less than or equal to the Initial Price, the Transaction
     Value.

               (2)  Following an Adjustment Event, the Maturity Price, as such
     term is used throughout the definition of Exchange Rate and in subparagraph
     (b)(1) above, shall be deemed to equal (A) if shares of AirTouch Common
     Stock are outstanding at Maturity, the Maturity Price of the AirTouch
     Common Stock, as adjusted pursuant to the provisions of paragraph (a)(iv)
     of this Section, plus the Transaction Value or (B) if shares of AirTouch
     Common Stock are not outstanding at Maturity, the Transaction Value.

               (3)  Notwithstanding the foregoing, with respect to any
     securities received in an Adjustment Event that (A) are (i) listed on a
     United States national securities exchange, (ii) reported on a United
     States national securities system subject to last sale reporting, (iii)
     traded in the over-the-counter market and reported on the National
     Quotation Bureau or similar organization or (iv) for which bid and ask
     prices are available from at least three nationally recognized investment
     banking firms and (B) are either (x) perpetual equity securities or (y)
     non-perpetual equity or debt securities with a stated maturity after the
     Stated Maturity ("Reported Securities"), the Company may, at its option, in
     lieu of delivering cash in respect of all or a percentage (selected by the
     Company in its discretion) of such Reported Securities received in an
     Adjustment Event, as determined in accordance with subparagraph (b)(1),
     deliver a number of such Reported Securities with a value equal to all cash
     amounts that would otherwise be deliverable in respect of all or such
     percentage of Reported Securities received in such Adjustment Event, as
     determined in accordance with clause (b) of the definition of Transaction
     Value set forth in Section 101; PROVIDED, HOWEVER, that (i) if such option
     is exercised in respect of less than all cash amounts that would otherwise
     be deliverable in respect of Reported Securities received in an Adjustment
     Event, the Company shall deliver all cash amounts as to which such option
     has not been exercised and (ii) the Company may not exercise such option if
     such Reported Securities have not yet been delivered to the Holders
     entitled thereto following such Adjustment Event or any record date with
     respect thereto.  If the Company delivers any Reported Securities, each
     Holder of a PIES will be 


                                       13
<PAGE>

     responsible for the payment of any and all brokerage and other 
     transaction costs upon the sale of such Reported Securities.  If, 
     following any Adjustment Event, any Reported Security ceases to qualify 
     as a Reported Security, then (x) the Company may no longer elect to 
     deliver such Reported Security in lieu of an equivalent amount of cash 
     and (y) notwithstanding clause (b) of the definition of Transaction 
     Value, the Transaction Value of such Reported Security shall mean the 
     fair market value of such Reported Security on the date such security 
     ceases to qualify as a Reported Security, as determined by a nationally 
     recognized investment banking firm retained for this purpose by the 
     Company.

               (4)  The amount of cash and/or the kind and number of securities
     into which the PIES shall be exchangeable after an Adjustment Event shall
     be subject to adjustment following the date of such Adjustment Event in the
     same manner and upon the occurrence of the same type of events as described
     in paragraphs (a) and (b) of this Section with respect to AirTouch Common
     Stock and AirTouch.

               (5)  For purposes of the foregoing, the term "Ordinary Cash
     Dividend" means, with respect to any consecutive 365-day period, any
     dividend with respect to AirTouch Common Stock paid in cash to the extent
     that the amount of such dividend, together with the aggregate amount of all
     other dividends on the AirTouch Common Stock paid in cash during such 
     365-day period, does not exceed on a per share basis 10% of the average of 
     the Closing Prices of the AirTouch Common Stock over such 365-day period 
     (the amount of cash dividends paid on a per share basis to be appropriately
     adjusted to reflect the occurrence during such period of any Adjustment
     Event described in Section 205(a)).  For purposes of this subparagraph
     (b)(5), any cash dividend shall be deemed to be paid as of the record date
     for such cash dividend.

          SECTION 206.  NOTICE OF ADJUSTMENTS AND CERTAIN OTHER EVENTS.

          (a)  Whenever the Exchange Rate is adjusted as herein provided or an
Adjustment Event occurs, the Company shall:

          (v)  forthwith compute the adjusted Exchange Rate (or Transaction
     Value) in accordance with Section 205 and prepare an Officers' Certificate
     signed by an officer of the Company setting forth the adjusted Exchange
     Rate (or Transaction Value), the method of calculation thereof in
     reasonable detail and the facts requiring such adjustment and upon which
     such adjustment is based, which certificate shall be conclusive, final and
     binding evidence of the correctness of the adjustment, and file such
     certificate forthwith with the Trustee; and 

          (vi)  within 10 Business Days following the occurrence of an event 
     that permits or requires an adjustment to the Exchange Rate pursuant to 
     Section 205(a) (each, a "Dilution 


                                       14
<PAGE>

     Event") or an Adjustment Event that permits or requires a change in the 
     consideration to be received by Holders pursuant to Section 205(b) (or, 
     in either case, if the Company is not aware of such occurrence, as soon 
     as practicable after becoming so aware), provide written notice to the 
     Trustee and to the Holders of the outstanding PIES of the occurrence of 
     such Dilution Event or Adjustment Event including a statement in 
     reasonable detail setting forth the method by which any adjustment to 
     the Exchange Rate or change in the consideration to be received was 
     determined and setting forth the revised Exchange Rate or consideration, 
     as the case may be, per PIES, PROVIDED, THAT, in respect of any 
     adjustment to the Maturity Price, such notice need only disclose the 
     factor by which the Maturity Price is to be multiplied pursuant to 
     Section 205(a)(iv) in order to determine which clause of the definition 
     of the Exchange Rate will apply at Maturity, it being understood that, 
     until Maturity, the Exchange Rate itself cannot be determined.

          (b)  In case at any time while any of the PIES are outstanding the
Company receives notice that:

          (vii) AirTouch shall declare a dividend (or any other distribution) on
     or in respect of the AirTouch Common Stock to which Section 205(a)(i) or
     (ii) shall apply (other than any cash dividends and distributions, if any,
     paid from time to time by AirTouch that do not constitute Ordinary Cash
     Dividends);

          (viii) AirTouch shall authorize the issuance to all holders of 
     AirTouch Common Stock of rights or warrants to subscribe for or purchase 
     shares of AirTouch Common Stock or of any other subscription rights or 
     warrants;

          (ix) there shall occur any conversion or reclassification of AirTouch
     Common Stock (other than a subdivision or combination of outstanding shares
     of such AirTouch Common Stock) or any consolidation, merger or
     reorganization to which AirTouch is a party and for which approval of any
     stockholders of AirTouch is required, or the sale or transfer of all or
     substantially all of the assets of AirTouch; or

          (x) there shall occur the voluntary or involuntary dissolution,
     liquidation or winding up of AirTouch;

     (xi) then the Company shall promptly cause to be delivered to the 
     Trustee and any applicable Paying Agent and filed at the office or 
     agency maintained for the purpose of exchange of PIES at Maturity in the 
     Borough of Manhattan, in The City of New York by the Trustee (or any 
     applicable Paying Agent), and shall promptly cause to be mailed to the 
     Holders of PIES at their last addresses as they shall appear upon the 
     registration books of the Security Registrar, at least 10 days before 
     the date hereinafter specified (or the earlier of the dates hereinafter 
     specified, in the event that more than one is specified), a notice 
     stating (x) the date on which a record is to be taken for the purpose of 
     such dividend, distribution or grant of rights or warrants, or, if a 
     record is not to be taken, the date as of which the holders of AirTouch 
     Common Stock of record to be entitled to such 


                                       15
<PAGE>

     dividend, distribution or grant of rights or warrants are to be 
     determined, or (y) the date, if known by the Company, on which such 
     reclassification, consolidation, merger, sale, transfer, dissolution, 
     liquidation or winding up is expected to become effective.  Following 
     any Adjustment Event, the provisions of this paragraph (b) shall apply 
     with respect to any Reported Securities in the same manner as with 
     respect to AirTouch and the AirTouch Common Stock

          (c)  On or prior to the twenty-first Business Day preceding the Stated
Maturity of the PIES, the Company will provide notice to the Holders of record
of the PIES and to the Trustee and will publish a notice in a daily newspaper of
national circulation stating whether the Company will deliver, in accordance
with Section 202, AirTouch Common Stock, cash (and/or, in accordance with
Section 205(b), cash or Reported Securities) or a combination thereof upon the
mandatory exchange of the principal amount of the PIES and, if a combination of
cash or such securities, the relative proportion of each.  After the close of
business on the Business Day immediately preceding the Stated Maturity of the
PIES, the Company shall notify the Trustee in writing of the number of shares of
AirTouch Common Stock and/or Reported Securities, or the amount of cash, to be
delivered per PIES.

          (d)  An election pursuant to the first paragraph of Section 204 will
be effective if, not less than twenty-one Business Days nor more than sixty
Business Days preceding the Stated Maturity of the PIES, the Company provides
notice to Holders of record of the PIES and to the Trustee and publishes a
notice in a daily newspaper of national circulation stating the Company's
election to extend the maturity of the PIES to November [__], 2001 or February
[__], 2002, as the case may be, in accordance with Section 204, subject, in
either case, to Post-Extension Termination in accordance with Section 204.

          (e)  An election pursuant to the second paragraph of Section 204 will
be effective if (subject to satisfaction of any additional conditions set forth
in Section 204), not less than twenty-one Business Days nor more than thirty
Business Days preceding the anticipated settlement date of a Refinancing Offer,
the Company (i) gives notice to the Holders of record of the PIES (a) of the
Company's intention to launch and consummate a Refinancing Offer and of such
anticipated settlement date and (b) that, pursuant to the terms described
herein, the PIES will be terminated and repurchased by Company on the
anticipated settlement date of the Refinancing Offer and (ii) simultaneously
with giving such notice, gives notice to The Depository Trust Company and the
Trustee and publishes a notice in a daily newspaper of national circulation
stating whether the principal amount of each PIES will be exchanged for shares
of AirTouch Common Stock, cash or a combination thereof and, if a combination of
cash and shares, the relative proportions thereof.

          SECTION 207.  TAXES. 


                                       16
<PAGE>

          The Company will pay any and all documentary, stamp, transfer or
similar taxes that may be payable in respect of the transfer and delivery of
AirTouch Common Stock (or Reported Securities) pursuant hereto; PROVIDED,
HOWEVER, that the Company shall not be required to pay any such tax which may be
payable in respect of any transfer involved in the delivery of AirTouch Common
Stock (or Reported Securities) in a name other than that in which the PIES so
exchanged were registered, and no such transfer or delivery shall be made unless
and until the person requesting such transfer has paid to the Company the amount
of any such tax, or has established, to the satisfaction of the Company, that
such tax has been paid. 

          SECTION 2.08.  DELIVERY OF SECURITIES UPON MATURITY.

          All AirTouch Common Stock and Reported Securities deliverable to
Holders upon the Maturity of the PIES shall be delivered to such Holders,
whenever practicable, in such manner (such as by book-entry transfer) so as to
assure same-day transfer of such Securities to Holders and otherwise in the
manner customary at such time for delivery of such Securities and Securities of
the same type.

                               ARTICLE III

                                Covenants

          SECTION 301.  SHARES FREE AND CLEAR.

          With respect to the PIES only and for the benefit of only the Holders
thereof, the Company covenants and warrants that upon exchange of a PIES at
Maturity pursuant to the Indenture and this Supplemental Indenture, the Holder
of a PIES shall receive valid title to the AirTouch Common Stock (and, in the
event an Adjustment Event has occurred and Reported Securities are delivered,
the Reported Securities) for which such PIES is at such time exchangeable
pursuant to this Indenture, free and clear of any and all liens, claims, charges
and encumbrances whatsoever.  To the extent as provided in Section 207, the
Company will pay all taxes and charges with respect to the delivery of AirTouch
Common Stock (and Reported Securities) delivered in exchange for PIES hereunder.
In addition, the Company further warrants that any AirTouch Common Stock (and
Reported Securities) so delivered in exchange for PIES hereunder shall be free
of any transfer restrictions (other than such as are solely attributable to any
Holder's status as an affiliate of AirTouch or the issuer of such Reported

          of its obligations under Section 8.01 hereof to deposit with the 
          Trustee from time to time cash and securities in the amounts and, 
          in the case of the securities, of the type required by the

          receipt of notice of such failure by the Trustee or the Company."

          Section 303  DISCHARGE OF INDENTURE.

          With respect to the PIES only and for the benefit of only the Holders
thereof, Sections 8.01, 8.02 and 8.03 of the Indenture are amended and restated
to read in their entirety as follows:

          "Section 8.01  Defeasance.

               (a)  The Company shall cease to be under any obligation with
          respect to the PIES or with respect to this Indenture with respect to
          the PIES (other than the Continuing Obligations) on the 91st day after
          the following applicable conditions have been satisfied (and
          thereafter such non-compliance shall not constitute an Event of
          Default):  (i) the Company shall have irrevocably deposited with
          respect to the PIES in trust with the Trustee as trust funds,
          specifically pledged as security for, and dedicated solely to, the
          benefit of the Holders with respect to each PIES (A) the maximum
          number of shares of AirTouch Common Stock and of any Reported
          Securities, in either case, that could (based on the Share Components
          of the Exchange Rate at the time of deposit and assuming no exercise
          of the Cash Delivery option and full exercise of the option to deliver
          Reported Securities in lieu of cash in respect of such securities
          received in an Adjustment Event) be deliverable at Maturity, with
          respect to such PIES and (B) U.S. Government Obligations (as defined
          below), cash or a combination thereof, in any case, sufficient
          (without any reinvestment of interest or principal of such U.S.
          Government Obligations), in the opinion of a nationally recognized
          firm of independent public accountants expressed in a written
          certification thereof delivered to the Trustee at or prior to the time
          of such deposit, to pay not later than one day before due (1) all
          interest on such PIES to Stated Maturity and (2) the maximum cash
          amount with respect to such PIES that could be deliverable at Maturity
          with respect to any cash or property other than Reported Securities
          received in an Adjustment Event; (ii) no Default or Event of Default
          with respect to this Indenture or the PIES shall have occurred and be
          continuing on the date of such deposit or shall occur as a result of
          such deposit and such deposit will not result in a breach or violation
          of, or constitute a default under, any other instrument to which the
          Company is a party or by which it is bound, as evidenced to the


                                       18
<PAGE>

          Trustee in an Officers' Certificate delivered to the Trustee
          concurrently with such deposit; (iii) the Company has delivered to the
          Trustee an Opinion of Counsel in form satisfactory to the Trustee to
          the effect that Holders will not recognize income, gain or loss for
          Federal income tax purposes as a result of the Company's exercise of
          its option described in clause (i) and will be subject to Federal
          income tax on the same amount and in the same manner and at the same
          time as would have been the case if such option had not been
          exercised; (iv) the Company has paid or duly provided for payment of
          all amounts then due to the Trustee pursuant to the terms of this
          Indenture; (v) the Company has delivered to the Trustee an Officers'
          Certificate and an Opinion of Counsel, each stating, as applicable,
          that all conditions precedent provided for herein relating to the
          discharge of the Company's obligations to comply with certain
          covenants have been complied with; and (vi) the Company has delivered
          to the Trustee an Opinion of Counsel to the effect that after the
          passage of 90 days after the deposit, the trust funds will not be
          subject to the effect of any applicable Federal or State bankruptcy,
          insolvency or similar law.

               (b)  If any Dilution Event or any Adjustment Event shall occur,
          in either case, following a deposit (an "initial deposit") pursuant to
          paragraph (a) of this Section, then the Company shall make an
          additional deposit with the Trustee (or the Trustee shall remit to the
          Company) a number of shares of AirTouch Common Stock, Reported
          Securities, U.S. Government Obligations and an amount of cash such
          that the Trustee will hold the number of such securities and amount of
          cash that it would be entitled to hold if such initial deposit (and
          any permitted substitutions described below) were made immediately
          following such event.

               (c)  Unless the Company is in default under the Indenture, it
          may, at its option, substitute for the shares of AirTouch Common Stock
          or Reported Securities deposited pursuant to paragraph (a) of this
          Section U.S. Government Obligations having an aggregate market value
          at the time of substitution and at daily mark-to-market valuations
          thereafter of not less than 125% (except as provided below) of the
          product of the Closing Price per share of AirTouch Common Stock or
          security of Reported Securities, respectively, on the day immediately
          preceding the time of each substitution or valuation multiplied by the
          number of shares of AirTouch Common Stock or Reported Securities,
          respectively, for which such obligations are being substituted.  The
          Company may, at its option substitute U.S. Government Obligations for
          shares of AirTouch 


                                       19
<PAGE>

          Common Stock or for Reported Securities pledged after any dilution 
          adjustment or Adjustment Event in the same manner described above 
          for such securities pledged pursuant to paragraph (a) of this 
          Section. Prior to any substitution made pursuant to this paragraph, 
          the Company shall delivery to the Trustee a legal opinion of 
          nationally recognized counsel to the effect that the deposit of 
          U.S. Government Obligations having an aggregate market value of 
          125% of the amount specified above is sufficient to avoid a 
          violation of any applicable federal law or regulation.  If the 
          Company delivers an opinion to the foregoing effect but with 
          respect to a greater percentage, then all references in this 
          paragraph to 125% shall be deemed to be references to such greater 
          amount, as in the opinion of such counsel, shall be required to 
          avoid any such violation.
               

               (d)  Except in the case of U.S. Government Obligations deposited
          in respect of a cash amount that could be deliverable at Maturity, the
          Trustee will promptly pay over to the Company any dividends, interest,
          principal or other payments received by the Trustee in respect of any
          securities and deposit with it, unless the Company is in default on
          its obligations under the PIES, or unless the payment of such amount
          to the Company would cause the cash and securities on deposit with the
          Trustee to become insufficient under the provisions of this Section
          8.01.

               (e)  Notwithstanding anything to the contrary in this Section
          8.01, the Company shall not substitute U.S. Government Obligations and
          shall not replace AirTouch Common Stock or Reported Securities within
          the 21 Business Days preceding Stated Maturity.  If at Maturity the
          number of shares of AirTouch Common Stock (or, after an Adjustment
          Event, Reported Securities) on deposit with the Trustee pursuant to
          this Article 8 is insufficient to meet the obligations (based on the
          actual Maturity Price and the assumption that the Cash Delivery Option
          is not exercised) under any PIES to deliver such securities, the
          Trustee will distribute to the Holders pro rata all of such securities
          held by it and, as to the remaining obligation to deliver such
          securities, shall deliver the cash equivalent that the Company would
          have been allowed to deliver thereunder, in the form of cash generated
          from the liquidation of U.S. Government Obligations then pledged by
          the Company.



                                       20

<PAGE>

         (f)  Unless the Trustee holds, as of the 21st Business Day
    preceding Stated Maturity, sufficient shares of AirTouch Common Stock
    with which to settle the PIES in their entirety, the Company will
    notify The Depository Trust Company and the Trustee and publish a
    notice in a daily newspaper of national circulation stating the
    proportions of securities and cash that will be delivered at Maturity. 
    The Trustee shall promptly remit to the Company any excess cash or
    securities on deposit after all amounts owing in respect of the PIES
    at Maturity have been paid in full.

         (g)  After a deposit by the Company in accordance with this
    Section in respect of the PIES, the Trustee upon request shall
    acknowledge in writing the discharge of the Company's obligations
    under the PIES in respect of which the deposit has been made and under
    the Indenture with respect to the PIES except for those Continuing
    Obligations specified above.

         (h)  U.S. Government Obligations shall not be callable at the
    issuer's option.

         (i)  "U.S. Government Obligations" means (i) direct obligations
    of the United States of America for the payment of which the full
    faith and credit of the United States or America is pledged; or (ii)
    obligations of a person controlled or supervised by and acting as an
    agency or instrumentality of the United States of America, the full
    and timely payment of which is unconditionally guaranteed as a full
    faith and credit obligation by the United States of America.

    Section 8.02  Application of Trust Money.

         The Trustee shall hold in trust shares of AirTouch Common
         Stock, Reported Securities, U.S. Government Obligations,
         cash or a combination thereof deposited with it pursuant to
         Section 8.01.  It shall apply the deposited AirTouch Common
         Stock, Reported Securities, cash or cash generated from the
         liquidation of the U.S. Government Obligations pledged by
         the Company through any Paying Agent and in accordance with
         this Supplemental Indenture to the payment of principal of
         and interest on the PIES.

    Section 8.03  Repayment to the Company.

         The Trustee and any Paying Agent shall promptly pay to the

                                   21
<PAGE>


         Company upon request any money held by them for the payment
         of principal or interest that remains unclaimed for two
         years.  After that, Securityholders entitled to the money
         must look to the Company for payment as general creditors
         unless an abandoned property law designates another person. 
         Upon payment to the Company, the Trustee and any Paying
         Agent are released of any further obligation or liability
         with respect to the utilization of such moneys."

         SECTION 304.  TAX TREATMENT.

         The parties hereto hereby agree, and each Holder of a PIES by its
purchase of a PIES hereby agrees:

         (i) to treat, for U.S. federal income tax purposes, each PIES as a 
    forward purchase contract to purchase AirTouch Common Stock at Maturity 
    (including as a result of acceleration or otherwise) (the "FORWARD 
    PURCHASE CONTRACT CHARACTERIZATION"), under the terms of which contract 
    (a) at the time of issuance of the PIES the Holder deposits irrevocably 
    with the Company a fixed amount of cash equal to the purchase price of 
    the PIES to assure the fulfillment of the Holder's purchase obligation 
    described in clause (c) below, which deposit will unconditionally and 
    irrevocably be applied at Maturity to satisfy such obligation, (b) until 
    Maturity the Company will be obligated to pay interest on such deposit at 
    a rate equal to the stated rate of interest on the PIES as compensation 
    to the Holder for the Company's use of such cash deposit during the term 
    of the PIES, and (c) at Maturity such cash deposit unconditionally and 
    irrevocably will be applied by the Company in full satisfaction of the 
    Holder's obligation under the forward purchase contract, and the Company 
    will deliver to the Holder the number of AirTouch Common Shares that the 
    Holder is entitled to receive at that time pursuant to the terms of the 
    PIES (subject to the Company's right to deliver cash in lieu of the 
    AirTouch Common Stock);

        (ii) to treat, consistent with the above characterization, (x) amounts
    paid to the Company in respect of the original issue of a PIES as allocable
    in their entirety to the amount of the cash deposit attributable to such
    PIES and (y) amounts denominated as interest that are payable with respect
    to the PIES as interest payable on the amount of such deposit, includible
    annually in the income of the Holder as interest income in accordance with
    its method of accounting;

        (iii) not to treat the delivery of any portion of the AirTouch Common
    Stock, cash or Reported Securities to be delivered pursuant to this
    Agreement (other than in respect of stated interest) as the payment of
    interest or ordinary income; and

        (iv) to file all U.S. federal, state and local income and franchise
    tax returns

                                     22

     consistent with the forward purchase contract characterization
    (unless required otherwise by an applicable taxing authority).

described below), and to pay interest (computed on the basis of a 360-day 
year of twelve 30-day months) on such principal amount from August [15], 
1998, or from the most recent Interest Payment Date (as defined below) to 
which interest has been paid or duly provided for, quarterly on February [15]
, May [15], August [15], and November [15] of each year (each, an "Interest 
Payment Date" and, collectively, the "Interest Payment Dates"), commencing 
November [15], 1998, at the rate per annum specified in the title of this 
note, until the principal hereof is paid or made available for payment.  The 
interest so payable, and punctually paid or duly provided for, on any 
Interest Payment Date will, as provided in said Indenture, be paid to the 
person in whose name this PIES (or the PIES in exchange or substitution for 
which this PIES was issued) is registered at the close of business on the 
Regular Record Date (as defined below) for interest payable on such Interest 
Payment Date.  The "Regular Record Date" for any interest payment is the 
close of business on the last day of the calendar month immediately preceding 
the relevant Interest Payment Date, whether or not a Business Day (as defined 
below), PROVIDED, that interest payable at Maturity shall be payable to the 
person to whom the principal hereof is payable.  In any case where such 
Interest Payment Date shall not be a Business Day, then (notwithstanding any 
other provision of said Indenture or this PIES) payment of such interest need 
not be made on such date, but may be made on the next succeeding Business Day 
with the same force and effect as if made on such date, and, if such payment 
is so made, no interest shall accrue for the period from and after such date. 
 Any such interest not so punctually paid or duly provided for shall 
forthwith cease to be payable to the registered Holder on such Regular Record 
Date, as the case may be, and may be paid to the person in whose name this 
PIES (or the PIES in exchange or substitution for which this PIES was issued) 
is registered at the close of business on a record date for the payment of 
such interest to be fixed by the Trustee for the PIES, notice whereof shall 
be given to Holders of the PIES not less than 10 days prior to such record 
date, or may be paid at any time in any other lawful manner not inconsistent 
with the requirements of any securities exchange on which the PIES may be 
listed, and upon such notice as may be required by such exchange.  At 
Maturity, the principal amount of this PIES will be mandatorily exchanged 
into a number of shares of Common Stock, par value $.01 per share (the 
"AirTouch Common Stock"), of AirTouch Communications, Inc. ("AirTouch") at 
the Exchange Rate (as defined below).  The "Exchange Rate" is equal to (a) if 
the Maturity Price (as defined below) is greater than or equal to $- (the 
"Threshold Appreciation Price"),  - shares of AirTouch Common Stock per PIES, 
(b) if the Maturity Price is less than the Threshold Appreciation Price but 
is greater than $- (the "Initial Price"), a fraction of one share of AirTouch 
Common Stock per PIES equal to the quotient of (i) the Initial Price divided 
by (ii) the Maturity Price (such fractional share being calculated to the 
nearest 1/10,000th of a share or, if there is not a nearest 1/10,000th of a 
share, to the next higher 1/10,000th of a share) and (c) if the Maturity 
Price is less than or equal to the Initial Price, one share of AirTouch 
Common Stock per PIES.  ACCORDINGLY, THE VALUE OF THE AIRTOUCH COMMON STOCK 
TO BE RECEIVED BY HOLDERS OF THE PIES (OR, AS DISCUSSED BELOW, THE CASH 
EQUIVALENT FOR ALL OR PART THEREOF OR OTHER CONSIDERATION THAT MAY BE 
RECEIVED IN LIEU OF OR IN ADDITION TO SUCH SHARES) AT MATURITY MAY BE LESS 
THAN THE PRINCIPAL AMOUNT OF 

                                    27

<PAGE>

SUCH PIES. Any shares of AirTouch Common Stock delivered by the Company to 
the Holders of the PIES that are not affiliated with AirTouch shall be free 
of any transfer restrictions, and the Holders of PIES will be responsible for 
the payment of any and all brokerage costs upon the subsequent sale of such 
shares.  No fractional shares of AirTouch Common Stock will be issued at 
Maturity as provided in the Indenture.  The Company may at its option deliver 
cash in lieu of delivering all or a portion (such portion to be selected by 
the Company in its discretion) of the shares of AirTouch Common Stock 
otherwise deliverable at Maturity (the "Cash Delivery Option").  The amount 
of cash deliverable in respect of each PIES (calculated to the nearest 
1/100th of a dollar per PIES or, if there is not a nearest 1/100th of a 
dollar, then to the next higher 1/100th of a dollar) shall be equal to the 
product of the number of shares of AirTouch Common Stock otherwise 
deliverable in respect of such PIES on the date of Maturity multiplied by the 
Maturity Price.  An election to exercise the Cash Delivery Option with 
respect to less than all of the shares of AirTouch Common Stock otherwise 
deliverable at Maturity shall not in any way limit the Company's obligation 
to deliver the remaining shares of AirTouch Common Stock otherwise 
deliverable at Maturity.  Notwithstanding the foregoing, (i) in the case of 
certain dilution events, the Exchange Rate will be subject to adjustment and 
(ii) in the case of certain adjustment events, the consideration received by 
Holders of PIES at Maturity will be other securities and/or cash, each as 
provided in the Indenture.

          The "Maturity Price" is defined as the average Closing Price per 
share of AirTouch Common Stock on the 20 Trading Days immediately prior to, 
but not including, the date of Maturity or, under certain circumstances, the 
market value per share of AirTouch Common Stock as of the date of Maturity as 
determined by a nationally recognized independent investment banking firm 
retained for such purpose by the Company, as provided in the Indenture, or, 
under certain other circumstances, the Closing Price per share of AirTouch 
Common Stock on the Trading Day immediately preceding the date that a 
Refinancing Offer (as defined in the Indenture) is priced (the "Pricing 
Date") or, if such Refinancing Offer is priced after 4:00 p.m., New York 
time, on the Pricing Date, the Closing Price per share on the Pricing Date, 
as provided in the Indenture.  The "Closing Price" of any security on any 
date of determination means (i) the closing sale price (or, if no closing 
price is reported, the last reported sale price) of such security (regular 
way) on the NYSE on such date, (ii) if such security is not listed for 
trading on the NYSE on any such date, as reported in the composite 
transactions for the principal United States securities exchange on which 
such security is so listed, (iii) if such security is not so listed on a 
United States national or regional securities exchange, as reported by the 
NASDAQ National Market, or (iv) if such security is not so reported, the last 
quoted bid price for such security in the over-the-counter market as reported 
by the National Quotation Bureau or similar organization. For purposes of 
determining the Maturity Price, the Closing Price of any securities on any 
day prior to any "ex-dividend" date occurring during the relevant 20 Trading 
Day Period for any dividend paid or to be paid with respect to such security 
should be reduced by the amount of such dividend.  A "Trading Day" is defined 
as a day on which the security the Closing Price of which is being determined 
(i) is not suspended from trading on any national or regional securities 
exchange or association or over-the-counter market at the close of business 
and (ii) has traded at 

                                    28

<PAGE>

least once on the national or regional securities exchange or association or 
over-the-counter market that is the primary market for the trading of such 
security.  "Business Day" means any day that is not a Saturday, a Sunday or a 
day on which the NYSE, banking institutions or trust companies in The City of 
New York, New York are authorized or obligated by law or executive order to 
close.

          Interest on this PIES will be payable, and delivery of AirTouch 
Common Stock and/or such other consideration as permitted or required herein 
(or, at the Company's option, cash in an amount equal to the value of such 
AirTouch Common Stock and/or other consideration) in exchange for the 
principal amount of this PIES at Maturity will be made upon surrender of this 
PIES, at the office or agency of the Company maintained for that purpose in 
The City of New York, New York, and payment of interest on (and, if the 
Company elects not to deliver AirTouch Common Stock and/or other securities 
upon exchange at Maturity, the cash equivalent thereof payable upon exchange 
for the principal amount of) this PIES will be made in such coin or currency 
of the United States of America as at the time of payment is legal tender for 
payment of public and private debts; PROVIDED, HOWEVER, that at the option of 
the Company payment of interest may be made by check mailed to the address of 
the person entitled thereto as such address shall appear on the register for 
the PIES.

          ADDITIONAL PROVISIONS OF THIS PIES ARE CONTAINED ON THE REVERSE 
HEREOF AND SUCH PROVISIONS SHALL HAVE THE SAME EFFECT AS THOUGH FULLY SET 
FORTH IN THIS PLACE.

          Unless the certificate of authentication hereon has been executed 
by or on behalf of the Trustee for this PIES by manual signature, this PIES 
shall not be entitled to any benefit under the Indenture, or be valid or 
obligatory for any purpose.  "PIES" and "Premium Income Exchangeable 
Securities" are service marks of Lehman Brothers Inc.

                              Form of Reverse of PIES

                              MEDIAONE GROUP, INC.

                     ___% Exchangeable Note due August 15, 2001

                  (Subject to Exchange at Maturity into Shares of
                     Common Stock, Par Value $.01 Per Share,
                         of AirTouch Communications, Inc.) 

          This PIES is one of a duly authorized issue of unsubordinated 
debentures, notes, or other evidences of indebtedness (hereinafter called the 
"Securities") of the Company of the Series hereinafter specified, which 
Series is limited in aggregate principal amount to $-, all such Securities 
issued and to be issued under an indenture dated as of November 13, 1995 
between the Company and The First National Bank of Chicago, as Trustee, as 
supplemented by a First Supplemental Indenture dated as of December 6, 1995, 
a Second Supplemental Indenture dated as of May 8, 1996 and a Third 
Supplemental Indenture dated as of August [  ], 1998 (as so supplemented and 
as may be further supplemented from time to time, the "Indenture") between 
the Company and The First National Bank of Chicago as trustee (herein called 
the "Trustee," which term includes any successor Trustee under the 
Indenture), pursuant to which the Company has designated The First National 
Bank of Chicago as Trustee for the PIES, to which Indenture and all other 
indentures supplemental thereto reference is hereby made for a statement of 
the rights and limitation of rights thereunder of the Holders of the 
Securities and of the rights, obligations, duties and immunities of the 
Trustee for each Series of Securities and of the Company, and the terms upon 
which the Securities are and are to be authenticated and delivered.  As 
provided in the Indenture, the Securities may be issued in one or more 
Series, which different Series may be issued in various aggregate principal 
amounts, may be denominated in currencies other than U.S. Dollars, (including 
composite currencies), may mature at different times, may bear interest, if 
any, at different rates, may be subject to different redemption provisions, 
if any, may be subject to different sinking fund or other purchase 
provisions, if any, may be subject to different covenants and Events of 
Default and may otherwise vary as in the Indenture provided or permitted.  
This PIES is one of a Series of the Securities designated as ___% 
Exchangeable Notes Due August 15, 2001. 

          The PIES may not be redeemed or terminated prior to Stated Maturity 
(except as provided in the Indenture) and are not entitled to the benefit of 
any sinking fund.

          The Company may at its option elect to extend the Stated Maturity 
of the PIES to November [__], 2001 and may further elect to extend the 
maturity of the PIES to February [__], 2002 (each, an "Extension Period") 
under certain circumstances, 

                                32

<PAGE>

subject, in either case, to Post-Extension Termination (as defined in the 
Indenture).  In the event that the Company exercises its option to extend the 
maturity of the PIES to February __, 2002, interest at the rate set forth 
above will continue to accrue on the PIES until Maturity and additional 
interest will accrue in arrears, commencing November [__], 2001 until 
Maturity (including by Post-Extension Termination), at a rate per annum equal 
to 0.5% of the principal amount of the PIES.  Such additional interest shall 
be payable in the same manner, at the same time and to the same Holders as 
other interest payments required to be made under the PIES.

     The Company may elect to cause all but not less than all of the PIES to 
be terminated and repaid at any time within an Extension Period upon 
completion of a Refinancing Offer.  The Company may exercise this election 
upon satisfaction of certain conditions described in the Indenture.  The 
related date of Maturity for the PIES shall be the anticipated settlement 
date indicated in such notice or, if two Business Days' prior notice to 
Holders thereof is given, such later date as the Refinancing Offer actually 
settles.

     The provisions contained in the Indenture for defeasance and discharge 
of the Company's obligations upon compliance by the Company with certain 
conditions set forth therein will be applicable to the PIES.

     If an Event of Default with respect to the PIES, as defined in the 
Indenture, shall occur and be continuing, the principal of all PIES may be 
declared due and payable and therefore will result in the mandatory exchange 
of the principal amount thereof for AirTouch Common Stock and/or other 
consideration as permitted or required under the terms hereof (or, at the 
Company's option, cash), all in the manner and with the effect provided in 
the Indenture. 

     The Indenture permits, with certain exceptions as therein provided, the 
amendment thereof and the modification of the rights and obligations of the 
Company and the rights of the Holders of the Securities of each Series under 
the Indenture at any time by the Company with the consent of the Holders of 
not less than a majority in aggregate principal amount of the Securities at 
the time outstanding of each Series to be affected thereby.  The Indenture 
also contains provisions permitting the Holders of specified percentages in 
aggregate principal amount of the Securities of any Series at the time 
outstanding, on behalf of the Holders of all the Securities of such Series, 
to waive compliance by the Company with certain provisions of the Indenture 
and certain past defaults under the Indenture and their consequences with 
respect to such Series. Any such consent or waiver by the Holder of this PIES 
shall be conclusive and binding upon such Holder and upon all future Holders 
of this PIES and of any PIES issued upon the transfer hereof or in exchange 
hereof or in lieu hereof whether or not notation of such consent of waiver is 
made upon this PIES. 

                                 33

<PAGE>

     No reference herein to the Indenture and no provision of this PIES or of 
the Indenture shall alter or impair the obligation of the Company, which is 
absolute and unconditional, to pay the principal of and interest on this PIES 
at the times, place and rate, and in the manner, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein 
set forth, this PIES is transferable on the register for the PIES, upon 
surrender of this PIES for registration of transfer at the office or agency 
of the Company to be maintained for that purpose in The City of New York, New 
York, or at any other office or agency of the Company maintained for that 
purpose, duly endorsed by, or accompanied by a written instrument of transfer 
in form satisfactory to the Company and the Registrar for the PIES duly 
executed by, the Holder hereof or his attorney duly authorized in writing, 
and thereupon one or more new PIES, of authorized denominations and for the 
same aggregate principal amount, will be issued to the designated transferee 
or transferees.  No service charge shall be made for any such transfer or 
exchange, but the Company may require payment of a sum sufficient to cover 
any tax or other governmental charge payable in connection with the 
registration of such transfer or exchange, other than certain exchanges not 
involving any transfer.

     Certain capitalized terms used in this PIES but not defined herein have 
the meanings set forth in the Indenture.

     THIS PIES SHALL FOR ALL PURPOSES BE GOVERNED BY, AND CONSTRUED IN 
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     The Company, the Trustee for the PIES and any agent of the Company or 
such Trustee may treat the person in whose name this PIES is registered as 
the owner hereof for the purpose of receiving payment as herein provided and 
for all other purposes, whether or not this PIES be overdue, and neither the 
Company, such Trustee nor any such agent shall be affected by notice to the 
contrary.
