     Agreement, dated as of June 18, 2001, between AT&T Wireless Services, Inc.,
a Delaware corporation (the "Company"), and Equiserve Trust Company, N.A., as
rights agent (the "Rights Agent").

     The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding as of the Rights Dividend
Effective Time (as hereinafter defined) on the date on which the Separation (as
hereinafter defined) occurs (the "Record Date"), which is expected to be July 9,
2001, each Right representing the right to purchase one one-hundredth of a
Preferred Share (as hereinafter defined), upon the terms and subject to the
conditions herein set forth, and has further authorized and directed the
issuance of one Right with respect to each Common Share that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).

     Accordingly, in consideration of the premises and the mutual agreements
herein set forth, the parties hereby agree as follows:

     Section 1. Definitions. For purposes of this Agreement, the following terms
have the meanings indicated:

     (a) "Acquiring Person" shall mean any Person who or which, together with
all Affiliates and Associates of such Person, shall be the Beneficial Owner of
15% or more of the Common Shares of the Company then outstanding, but shall not
include the Company, any Subsidiary of the Company, any employee benefit plan of
the Company or any Subsidiary of the Company, or any entity holding Common
Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Shares by the Company which, by reducing the number of
Common Shares of the Company outstanding, increases the proportionate number of
Common Shares of the Company beneficially owned by such Person to 15% or more of
the Common Shares of the Company then outstanding; provided, however, that, if a
Person shall become the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company, then such Person shall be deemed to
be an "Acquiring Person." Notwithstanding the foregoing, (i) if the Board of
Directors of the Company determines in good faith that a Person who would
otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of Common Shares so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement; (ii) AT&T Corp.,
a New York Corporation ("AT&T"), shall not be deemed to be an "Acquiring Person"
at any time prior to the effectiveness of the Separation; and (iii) neither NTT
DoCoMo, Inc., a company organized under the laws of Japan ("DoCoMo") nor any of
its Standstill Affiliates (as defined in the DoCoMo Investor Agreement (as
hereinafter defined)) shall be deemed to be an "Acquiring Person" solely by
virtue of its Beneficial Ownership, as of the effectiveness of the Separation,
of 15% or more of the Common Shares outstanding unless DoCoMo or any of its
Standstill Affiliates becomes
<PAGE>   5

the Beneficial Owner of any additional Common Shares of the Company other than
in connection with (w) a stock split, stock dividend or other similar
transaction initiated by the Company occurring after the date hereof, (x) at any
time when the standstill provisions of Section 3.6(a) of the DoCoMo Investor
Agreement are applicable to DoCoMo and the Standstill Affiliates, an acquisition
by DoCoMo or any Standstill Affiliate of Beneficial Ownership of Common Shares
of the Company that is not in violation of Section 3.6 of the DoCoMo Investor
Agreement, (y) at any time when DoCoMo has Preemptive Rights (as defined in the
DoCoMo Investor Agreement), an acquisition by DoCoMo or any Standstill Affiliate
of Beneficial Ownership of Common Shares of the Company pursuant to and in
accordance with Section 8.1 of the DoCoMo Investor Agreement, or (z) at any time
when the standstill provisions of Section 3.6(a) of the DoCoMo Investor
Agreement are not applicable to DoCoMo and the Standstill Affiliates, an
acquisition by DoCoMo or any Standstill Affiliate of Beneficial Ownership of
Common Shares of the Company immediately following which neither DoCoMo nor any
Standstill Affiliate would be an Acquiring Person if no effect were given to
this third sentence of this paragraph (a).

     (b) "Affiliate" shall have the meaning ascribed to such term in Rule 12b-2
of the General Rules and Regulations under the Exchange Act as in effect on the
date of this Agreement.

     (c) "Associate" shall have the meaning ascribed to such term in Rule 12b-2

to "beneficially own" any securities:

     arrangement or understanding (other than customary agreements with and
     between underwriters and selling group members with respect to a bona fide
     public offering of securities), or upon the exercise of conversion rights,
     exchange rights, rights (other than these Rights), warrants or options, or
     otherwise; provided, however, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, securities tendered pursuant
     to a tender or exchange offer made by or on behalf of such Person or any of
     such Person's Affiliates or Associates until such tendered securities are
     accepted for purchase or exchange; or (B) the right to vote pursuant to any
     agreement, arrangement or understanding; provided, however, that a Person
     shall not be deemed the Beneficial Owner of, or to beneficially own, any
     security if the agreement, arrangement or understanding to vote such
     security (1) arises solely from a revocable proxy or consent given to such
     Person in response to a public proxy or consent solicitation made pursuant
     to, and in accordance with, the applicable rules and regulations
     promulgated under the Exchange Act and (2) is not also then reportable on
     Schedule 13D under the Exchange Act (or any comparable or successor
     report); or

     customary agreements with and between underwriters and selling group
     members with respect to a bona fide public offering of securities) for the

     of the Company.

         Notwithstanding anything in this definition of Beneficial Ownership to
the contrary, the phrase "then outstanding," when used with reference to a

other Person or, if such other Person is a Subsidiary of another Person, the
Person or Persons which ultimately control such first-mentioned Person.

         (j) "Distribution Date" shall have the meaning set forth in Section

be evidenced (subject to the provisions of Section 3(b) hereof) by Book-Entry or
the certificates for Common Shares of the Company registered in the names of the
holders thereof (which certificates and Book-Entry shall also be deemed to be
Right Certificates) and not by separate Right Certificates, and (y) the right to
receive Right Certificates will be transferable only in connection with the
transfer of Common Shares of the Company. As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common Shares of the Company as of the Close of Business on the
Distribution Date, at the address of such holder shown on the records of the
Company, a Right Certificate, in substantially the form of Exhibit B hereto (a
"Right Certificate"), evidencing one Right for each Common Share so held. As of

Certificates.

         (b) On the Record Date, or as soon as practicable thereafter, the

substantially the form of Exhibit C hereto (the "Summary of Rights"), by
first-class, postage-prepaid mail, to each record holder of Common Shares as of

holder shown on the records of the Company. With respect to certificates or
Book-Entries for Common Shares of the Company outstanding as of the Record Date,
until the Distribution Date, the Rights will be evidenced by such certificates
or Book-Entries registered in the names of the holders thereof together with a
copy of the Summary of Rights attached thereto. Until the Distribution Date (or
the earlier of the Redemption Date or the Final Expiration Date),

                                      -5-
<PAGE>   9

the surrender for transfer of any Common Shares of the Company outstanding on
the Record Date represented by certificates or Book-Entry, with or without a
copy of the Summary of Rights attached thereto, shall also constitute the
transfer of the Rights associated with the Common Shares of the Company
represented thereby.

         (c) Certificates for Common Shares which become outstanding (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this paragraph (c)) after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them the following
legend:

      This certificate also evidences and entitles the holder hereof to certain
      rights as set forth in an Agreement between AT&T Wireless Services, Inc.
      and Equiserve Trust Company, N.A., dated as of June 18, 2001, as it may be
      amended from time to time (the "Agreement"), the terms of which are hereby
      incorporated herein by reference and a copy of which is on file at the
      principal executive offices of AT&T Wireless Services, Inc. Under certain
      circumstances, as set forth in the Agreement, such Rights (as defined in
      the Agreement) will be evidenced by separate certificates and will no
      longer be evidenced by this certificate. AT&T Wireless Services, Inc. will
      mail to the holder of this certificate a copy of the Agreement without
      charge after receipt of a written request therefor. As set forth in the
      Agreement, Rights beneficially owned by any Person (as defined in the
      Agreement) who becomes an Acquiring Person (as defined in the Agreement)
      become null and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares of the Company
represented by such certificates shall be evidenced by such certificates alone,
and the surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares of the Company
represented thereby. In the event that the Company purchases or acquires any
Common Shares of the Company after the Record Date but prior to the Distribution
Date, any Rights associated with such Common Shares of the Company shall be
deemed cancelled and retired so that the Company shall not be entitled to
exercise any Rights associated with the Common Shares of the Company which are
no longer outstanding.

         Section 4. Form of Right Certificates. The Right Certificates (and the
forms of election to purchase Preferred Shares and of assignment to be printed
on the reverse thereof) shall be substantially the same as Exhibit B hereto, and
may have such marks of identification or designation and such legends, summaries
or endorsements printed thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any applicable rule or regulation made
pursuant thereto or with any applicable rule or regulation of any stock exchange
or the National Association of Securities Dealers, Inc., or to conform to usage.
Subject to the provisions of Section 22 hereof, the Right Certificates shall
entitle the holders thereof to purchase such number of one one-hundredths of a
Preferred Share as shall be set forth therein at the price per one one-hundredth
of a Preferred Share set forth therein (the "Purchase Price"), but the number of
such one one-hundredths of a Preferred Share and the Purchase Price shall be
subject to adjustment as provided herein.

                                      -6-
<PAGE>   10

         Section 5. Countersignature and Registration. The Right Certificates
shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, its President, any of its Vice Presidents or its Chief
Financial Officer, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless countersigned. In
case any officer of the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the individual who signed such Right Certificates had not ceased to be such
officer of the Company; and any Right Certificate may be signed on behalf of the
Company by any individual who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of the execution of this Agreement any such
individual was not such an officer.

         Following the Distribution Date, the Rights Agent will keep or cause to
be kept, at its principal office, books for registration and transfer of the
Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

         Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. Subject
to the provisions of Section 14 hereof, at any time after the Close of Business
on the Distribution Date, and at or prior to the Close of Business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates
entitling the registered holder to purchase a like number of one one-hundredths
of a Preferred Share as the Right Certificate or Right Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Right Certificate or Right
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

            Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor

                                      -7-

to the Rights Agent for delivery to the registered holder in lieu of the Right
Certificate so lost, stolen, destroyed or mutilated.

         Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein), in whole or in
part, at any time after the Distribution Date, upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent,
together with payment of the Purchase Price for each one one-hundredth of a
Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the Close of Business on July 9, 2010 (the "Final Expiration
Date"), (ii) the time at which the Rights are redeemed as provided in Section 23
hereof (the "Redemption Date"), or (iii) the time at which such Rights are
exchanged as provided in Section 24 hereof.

         (b) The Purchase Price for each one one-hundredth of a Preferred Share
purchasable pursuant to the exercise of a Right shall initially be $100.00, and
shall be subject to adjustment from time to time as provided in Section 11 or 13
hereof, and shall be payable in lawful money of the United States of America in
accordance with paragraph (c) below.

         (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof by certified check, cashier's
check or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) (A) requisition from any transfer agent of the Preferred
Shares certificates for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes any such transfer agent to comply with all
such requests, or (B) requisition from the depositary agent depositary receipts
representing such number of one one-hundredths of a Preferred Share as are to be
purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent of the Preferred Shares
with such depositary agent) and the Company hereby directs such depositary agent
to comply with such request; (ii) when appropriate, requisition from the Company
the amount of cash to be paid in lieu of issuance of fractional shares in
accordance with Section 14 hereof; (iii) promptly after receipt of such
certificates or depositary receipts, cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate, registered in such
name or names as may be designated by such holder; and (iv) when appropriate,
after receipt, promptly deliver such cash to or upon the order of the registered
holder of such Right Certificate.

         (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to
such holder's duly authorized assigns, subject to the provisions of Section 14
hereof.

         Section 8. Cancellation and Destruction of Right Certificates. All
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for

                                      -8-
<PAGE>   12

cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall
be cancelled by it, and no Right Certificates shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Agreement. The
Company shall deliver to the Rights Agent for cancellation and retirement, and
the Rights Agent shall so cancel and retire, any other Right Certificate
purchased or acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all cancelled Right Certificates to the Company,
or shall, at the written request of the Company, destroy such cancelled Right
Certificates, and, in such case, shall deliver a certificate of destruction
thereof to the Company.

         Section 9. Availability of Preferred Shares. The Company covenants and
agrees that it will cause to be reserved and kept available out of its
authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7 hereof.
The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such Preferred Shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares.

         The Company further covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares upon the exercise of Rights. The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a Person other than, or the
issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Company's reasonable satisfaction that no
such tax is due.

         Section 10. Preferred Shares Record Date. Each Person in whose name any
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares represented thereby on, and such certificate shall be dated, the date
upon which the Right Certificate evidencing such Rights was duly surrendered and
payment of the Purchase Price (and any applicable transfer taxes) was made;
provided, however, that, if the date of such surrender and payment is a date
upon which the Preferred Shares transfer books of the Company are closed, such
Person shall be deemed to have become the record holder of such shares on, and
such certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any rights of a holder of Preferred Shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

         Section 11. Adjustment of Purchase Price, Number of Shares or Number of
Rights. The Purchase Price, the number of Preferred Shares covered by each Right
and the num-

                                      -9-
<PAGE>   13

ber of Rights outstanding are subject to adjustment from time to time as
provided in this Section 11.

         (a) (i) In the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, such holder would have
owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification; provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right.

         (ii) Subject to Section 24 hereof, in the event any Person becomes an
Acquiring Person, each holder of a Right shall thereafter have a right to
receive, upon exercise thereof at a price equal to the then current Purchase
Price multiplied by the number of one one-hundredths of a Preferred Share for
which a Right is then exercisable, in accordance with the terms of this
Agreement and in lieu of Preferred Shares, such number of Common Shares of the
Company as shall equal the result obtained by (A) multiplying the then current
Purchase Price by the number of one one-hundredths of a Preferred Share for
which a Right is then exercisable and dividing that product by (B) 50% of the
then current per share market price of the Common Shares of the Company
(determined pursuant to Section 11(d) hereof) on the date of the occurrence of
such event. In the event that any Person shall become an Acquiring Person and
the Rights shall then be outstanding, the Company shall not take any action
which would eliminate or diminish the benefits intended to be afforded by the
Rights.

         From and after the occurrence of such event, any Rights that are or
were acquired or beneficially owned by any Acquiring Person (or any Associate or
Affiliate of such Acquiring Person) shall be void, and any holder of such Rights
shall thereafter have no right to exercise such Rights under any provision of
this Agreement. No Right Certificate shall be issued pursuant to Section 3
hereof that represents Rights beneficially owned by an Acquiring Person whose
Rights would be void pursuant to the preceding sentence or any Associate or
Affiliate thereof; no Right Certificate shall be issued at any time upon the
transfer of any Rights to an Acquiring Person whose Rights would be void
pursuant to the preceding sentence or any Associate or Affiliate thereof or to
any nominee of such Acquiring Person, Associate or Affiliate; and any Right
Certificate delivered to the Rights Agent for transfer to an Acquiring Person
whose Rights would be void pursuant to the preceding sentence shall be
cancelled.

                                      -10-
<PAGE>   14

         (iii) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit the exercise in
full of the Rights in accordance with subparagraph (ii) above, the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exercise of the Rights. In the event the Company shall, after
good faith effort, be unable to take all such action as may be necessary to
authorize such additional Common Shares, the Company shall substitute, for each
Common Share that would otherwise be issuable upon exercise of a Right, a number
of Preferred Shares or fraction thereof such that the current per share market
price of one Preferred Share multiplied by such number or fraction is equal to
the current per share market price of one Common Share as of the date of
issuance of such Preferred Shares or fraction thereof.

         (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares (as defined in Section 11(d)) on such
record date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of Preferred
Shares which the aggregate offering price of the total number of Preferred
Shares and/or equivalent preferred shares so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such current market price and the denominator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
additional Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and holders
of the Rights. Preferred Shares owned by or held for the account of the Company
shall not be deemed outstanding for the purpose of any such computation. Such
adjustment shall be made successively whenever such a record date is fixed; and,
in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

         (c) In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a

                                      -11-
<PAGE>   15

fraction, the numerator of which shall be the then-current per share market
price of the Preferred Shares on such record date, less the fair market value
(as determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights Agent and holders of the Rights) of the portion
of the assets or evidences of indebtedness so to be distributed or of such
subscription rights or warrants applicable to one Preferred Share and the
denominator of which shall be such then-current per share market price of the
Preferred Shares on such record date; provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company to be issued
upon exercise of one Right. Such adjustments shall be made successively whenever
such a record date is fixed; and, in the event that such distribution is not so
made, the Purchase Price shall again be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

         (d) (i) For the purpose of any computation hereunder, the "current per
share market price" of any security (a "Security" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the 30 consecutive Trading Days
immediately prior to such date; provided, however, that, in the event that the
current per share market price of the Security is determined during a period
following the announcement by the issuer of such Security of (A) a dividend or
distribution on such Security payable in shares of such Security or Securities
convertible into such shares, or (B) any subdivision, combination or
reclassification of such Security and prior to the expiration of 30 Trading Days
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification, then, and in each such
case, the current per share market price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security. The
closing price for each day shall be the last sale price, regular way, reported
at or prior to 4:00 P.M. Eastern time or, in case no such sale takes place on
such day, the average of the bid and asked prices, regular way, reported as of
4:00 P.M. Eastern time, in either case, as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Security is not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the Security is
listed or admitted to trading or, if the Security is not listed or admitted to
trading on any national securities exchange, the last quoted price reported at
or prior to 4:00 P.M. Eastern time or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported as of 4:00
P.M. Eastern time by NASDAQ or such other system then in use, or, if on any such
date the Security is not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Security selected by the Board of Directors of the Company. The
term "Trading Day" shall mean a day on which the principal national securities
exchange on which the Security is listed or admitted to trading is open for the
transaction of business, or, if the Security is not listed or admitted to
trading on any national securities exchange, a Business Day.

(ii) For the purpose of any computation hereunder, the "current per share market
price" of the Preferred Shares shall be determined in accordance with the method
set forth in Section 11(d)(i). If the Preferred Shares are not publicly traded,
the "current per share market price" of the Preferred Shares shall be
conclusively deemed to be the current per share market price of the Common
Shares as determined pursuant to Section 11(d)(i) hereof (appropriately adjusted
to reflect

                                      -12-
<PAGE>   16

any stock split, stock dividend or similar transaction occurring after the date
hereof), multiplied by one hundred. If neither the Common Shares nor the
Preferred Shares are publicly held or so listed or traded, "current per share
market price" shall mean the fair value per share as determined in good faith by
the Board of Directors of the Company, whose determination shall be described in
a statement filed with the Rights Agent.

         (e) No adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Purchase
Price; provided, however, that any adjustments which by reason of this Section
11(e) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 11
shall be made to the nearest cent or to the nearest one one-millionth of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the transaction which requires such adjustment or (ii)
the date of the expiration of the right to exercise any Rights.

         (f) If, as a result of an adjustment made pursuant to Section 11(a)
hereof, the holder of any Right thereafter exercised shall become entitled to
receive any shares of capital stock of the Company other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Section 11(a) through (c) hereof, inclusive, and
the provisions of Sections 7, 9, 10 and 13 hereof with respect to the Preferred
Shares shall apply on like terms to any such other shares.

         (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

         (h) Unless the Company shall have exercised its election as provided in
Section 11(i) hereof, upon each adjustment of the Purchase Price as a result of
the calculations made in Sections 11(b) and (c) hereof, each Right outstanding
immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase, at the adjusted Purchase Price, that number of one
one-hundredths of a Preferred Share (calculated to the nearest one one-millionth
of a Preferred Share) obtained by (A) multiplying (x) the number of one
one-hundredths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (B) dividing the product so obtained by the
Purchase Price in effect immediately after such adjustment of the Purchase
Price.

         (i) The Company may elect, on or after the date of any adjustment of
the Purchase Price, to adjust the number of Rights in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one ten-thousandth) ob-

                                      -13-
<PAGE>   17

tained by dividing the Purchase Price in effect immediately prior to adjustment
of the Purchase Price by the Purchase Price in effect immediately after
adjustment of the Purchase Price. The Company shall make a public announcement
of its election to adjust the number of Rights, indicating the record date for
the adjustment, and, if known at the time, the amount of the adjustment to be
made. This record date may be the date on which the Purchase Price is adjusted
or any day thereafter, but, if the Right Certificates have been issued, shall be
at least 10 days later than the date of the public announcement. If Right
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(i), the Company shall, as promptly as practicable,
cause to be distributed to holders of record of Right Certificates on such
record date Right Certificates evidencing, subject to Section 14 hereof, the
additional Rights to which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall cause to be distributed to
such holders of record in substitution and replacement for the Right
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Right Certificates evidencing
all the Rights to which such holders shall be entitled after such adjustment.
Right Certificates so to be distributed shall be issued, executed and
countersigned in the manner provided for herein, and shall be registered in the
names of the holders of record of Right Certificates on the record date
specified in the public announcement.

         (j) Irrespective of any adjustment or change in the Purchase Price or
in the number of one one-hundredths of a Preferred Share issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter issued
may continue to express the Purchase Price and the number of one one-hundredths
of a Preferred Share which were expressed in the initial Right Certificates
issued hereunder.

         (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below one one-hundredth of the then par value, if any, of the
Preferred Shares issuable upon exercise of the Rights, the Company shall take
any corporate action which may, in the opinion of its counsel, be necessary in
order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.

         (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

         (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it, in its sole discretion, shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or

                                      -14-
<PAGE>   18

issuance of rights, options or warrants referred to in Section 11(b) hereof,
hereafter made by the Company to holders of the Preferred Shares shall not be
taxable to such stockholders.

         (n) In the event that, at any time after the date of this Agreement and
prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares, or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then, in any such case, (A)
the number of one one-hundredths of a Preferred Share purchasable after such
event upon proper exercise of each Right shall be determined by multiplying the
number of one one-hundredths of a Preferred Share so purchasable immediately
prior to such event by a fraction, the numerator of which is the number of
Common Shares outstanding immediately before such event and the denominator of
which is the number of Common Shares outstanding immediately after such event,
and (B) each Common Share outstanding immediately after such event shall have
issued with respect to it that number of Rights which each Common Share
outstanding immediately prior to such event had issued with respect to it. The
adjustments provided for in this Section 11(n) shall be made successively
whenever such a dividend is declared or paid or such a subdivision, combination
or consolidation is effected.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 or 13 hereof, the
Company shall promptly (a) prepare a certificate setting forth such adjustment
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Common Shares or the
Preferred Shares and the Securities and Exchange Commission a copy of such
certificate and (c) if such adjustment occurs at any time after the Distribution
Date, mail a brief summary thereof to each holder of a Right Certificate in
accordance with Section 25 hereof.

         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power. In the event, directly or indirectly, at any time after a Person
has become an Acquiring Person, (a) the Company shall consolidate with, or merge
with and into, any other Person, (b) any Person shall consolidate with the
Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or the Company) or cash or any
other property, or (c) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person other than the Company or one or more of its wholly-owned
Subsidiaries, then, and in each such case, proper provision shall be made so
that (i) each holder of a Right (except as otherwise provided herein) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price multiplied by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable and
dividing that

                                      -15-
<PAGE>   19

product by (B) 50% of the then current per share market price of the Common
Shares of such other Person (determined pursuant to Section 11(d) hereof) on the
date of consummation of such consolidation, merger, sale or transfer; (ii) the
issuer of such Common Shares shall thereafter be liable for, and shall assume,
by virtue of such consolidation, merger, sale or transfer, all the obligations
and duties of the Company pursuant to this Agreement; (iii) the term "Company"
shall thereafter be deemed to refer to such issuer; and (iv) such issuer shall
take such steps (including, but not limited to, the reservation of a sufficient
number of its Common Shares in accordance with Section 9 hereof) in connection
with such consummation as may be necessary to assure that the provisions hereof
shall thereafter be applicable, as nearly as reasonably may be, in relation to
the Common Shares of the Company thereafter deliverable upon the exercise of the
Rights. The Company shall not consummate any such consolidation, merger, sale or
transfer unless, prior thereto, the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing. The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights. The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

         Section 14. Fractional Rights and Fractional Shares. (a) The Company
shall not be required to issue fractions of Rights or to distribute Right
Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid and asked prices, regular way, in either case, as reported in
the principal consolidated transaction reporting system with respect to
securities listed or admitted to trading on the New York Stock Exchange or, if
the Rights are not listed or admitted to trading on the New York Stock Exchange,
as reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal national securities exchange on
which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the Company. If on any such date no such market maker is making a
market in the Rights, the fair value of the Rights on such date as determined in
good faith by the Board of Directors of the Company shall be used.

         (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-hundredth of a Preferred Share). Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred

                                      -16-
<PAGE>   20

Share may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; provided that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares
that are not integral multiples of one one-hundredth of a Preferred Share, the
Company shall pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For the purposes of
this Section 14(b), the current market value of a Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to the second
sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of such exercise.

         (c) The holder of a Right, by the acceptance of the Right, expressly
waives such holder's right to receive any fractional Rights or any fractional
shares upon exercise of a Right (except as provided above).

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in such holder's own behalf and
for such holder's own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement, and
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to, this Agreement.

         Section 16. Agreement of Right Holders. Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

         (a) prior to the Distribution Date, the Rights will be transferable
only in connection with the transfer of the Common Shares;

         (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

         (c) the Company and the Rights Agent may deem and treat the person in
whose name the Right Certificate (or, prior to the Distribution Date, the
associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate or the associated

                                      -17-
<PAGE>   21

Common Shares certificate made by anyone other than the Company or the Rights
Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent
shall be affected by any notice to the contrary.

         Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

         Section 18. Concerning the Rights Agent. The Company agrees to pay to
the Rights Agent reasonable compensation for all services rendered by it
hereunder, and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability, or expense incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability in the premises.

         The Rights Agent shall be protected and shall incur no liability for,
or in respect of any action taken, suffered or omitted by it in connection with,
its administration of this Agreement in reliance upon any Right Certificate or
certificate for the Preferred Shares or Common Shares or for other securities of
the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement, or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper
person or persons, or otherwise upon the advice of counsel as set forth in
Section 20 hereof.

         Section 19. Merger or Consolidation or Change of Name of Rights Agent.
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or any corporation succeeding to the stock transfer or
corporate trust powers of the Rights Agent or any successor Rights Agent, shall
be the successor to the Rights Agent under this Agreement without the execution
or filing of any paper or any further act on the part of any of the parties
hereto; provided that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at the
time such successor Rights Agent shall succeed to the agency created by this
Agreement, any of the Right Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the

                                      -18-
<PAGE>   22

predecessor Rights Agent and deliver such Right Certificates so countersigned;
and, in case at that time any of the Right Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Right
Certificates either in the name of the predecessor Rights Agent or in the name
of the successor Rights Agent; and, in all such cases, such Right Certificates
shall have the full force provided in the Right Certificates and in this
Agreement.

            In case at any time the name of the Rights Agent shall be changed
and at such time any of the Right Certificates shall have been countersigned but
not delivered, the Rights Agent may adopt the countersignature under its prior
name and deliver Right Certificates so countersigned; and, in case at that time
any of the Right Certificates shall not have been countersigned, the Rights
Agent may countersign such Right Certificates either in its prior name or in its
changed name; and, in all such cases, such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

         Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Right Certificates,
by their acceptance thereof, shall be bound:

         (a) The Rights Agent may consult with legal counsel (who may be legal
counsel for the Company), and the opinion of such counsel shall be full and
complete authorization and protection to the Rights Agent as to any action taken
or omitted by it in good faith and in accordance with such opinion.

         (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Chief Financial
Officer or the Secretary of the Company and delivered to the Rights Agent; and
such certificate shall be full authorization to the Rights Agent for any action
taken or suffered in good faith by it under the provisions of this Agreement in
reliance upon such certificate.

         (c) The Rights Agent shall be liable hereunder to the Company and any
other Person only for its own gross negligence, bad faith or willful misconduct.

         (d) The Rights Agent shall not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the Right
Certificates (except its countersignature thereof) or be required to verify the
same, but all such statements and recitals are and shall be deemed to have been
made by the Company only.

         (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall it
be re-

                                      -19-
<PAGE>   23

sponsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in
the terms of the Rights (including the manner, method or amount thereof)
provided for in Section 3, 11, 13, 23 or 24 hereof, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right Certificates after actual
notice that such change or adjustment is required); nor shall it by any act
hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

         (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.

         (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Secretary or the Chief Financial Officer of the Company,
and to apply to such officers for advice or instructions in connection with its
duties, and it shall not be liable for any action taken or suffered by it in
good faith in accordance with instructions of any such officer or for any delay
in acting while waiting for those instructions.

         (h) The Rights Agent and any stockholder, director, officer or employee
of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.

         (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct, provided that reasonable care was exercised in the
selection and continued employment thereof.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Shares or Preferred Shares by registered or certified mail, and to
the holders of the Right Certificates by first-class mail. The Company may
remove the Rights Agent or any successor Rights Agent upon 30 days' notice in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent of the Common Shares or Preferred Shares by
registered or certified mail, and to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appoint-

                                      -20-
<PAGE>   24

ment within a period of 30 days after giving notice of such removal or after it
has been notified in writing of such resignation or incapacity by the resigning
or incapacitated Rights Agent or by the holder of a Right Certificate (which
holder shall, with such notice, submit such holder's Right Certificate for
inspection by the Company), then the registered holder of any Right Certificate
may apply to any court of competent jurisdiction for the appointment of a new
Rights Agent. Any successor Rights Agent, whether appointed by the Company or by
such a court, shall be a corporation organized and doing business under the laws
of the United States or of the State of Delaware (or of any other state of the
United States so long as such corporation is authorized to do business as a
banking institution in the State of Delaware), in good standing, having an
office in the State of Delaware, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Shares
or Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Right Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates evidencing Rights in such form
as may be approved by the Board of Directors of the Company to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement.

         Section 23. Redemption. (a) The Board of Directors of the Company may,
at its option, at any time prior to such time as any Person becomes an Acquiring
Person, redeem all but not less than all the then outstanding Rights at a
redemption price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(such redemption price being hereinafter referred to as the "Redemption Price").
The redemption of the Rights by the Board of Directors of the Company may be
made effective at such time, on such basis and with such conditions as the Board
of Directors of the Company, in its sole discretion, may establish.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice, the right to
exercise the Rights will terminate and the only right thereafter of the holders
of Rights shall be to receive the Redemption Price. The Company shall promptly
give public notice of any such redemption; provided, however, that the failure
to give, or any defect in, any such notice shall not affect the validity of such
redemption. Within 10 days after such action of the Board of Directors of the
Company ordering the redemp-

                                      -21-
<PAGE>   25

tion of the Rights, the Company shall mail a notice of redemption to all the
holders of the then outstanding Rights at their last addresses as they appear
upon the registry books of the Rights Agent or, prior to the Distribution Date,
on the registry books of the transfer agent for the Common Shares. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of redemption will state
the method by which the payment of the Redemption Price will be made. Neither
the Company nor any of its Affiliates or Associates may redeem, acquire or
purchase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section 24 hereof, and other
than in connection with the purchase of Common Shares prior to the Distribution
Date.

         Section 24.Exchange. (a) The Board of Directors of the Company may, at
its option, at any time after any Person becomes an Acquiring Person, exchange
all or part of the then outstanding and exercisable Rights (which shall not
include Rights that have become void pursuant to the provisions of Section
11(a)(ii) hereof) for Common Shares at an exchange ratio of one Common Share per
Right, appropriately adjusted to reflect any adjustment in the number of Rights
pursuant to Section 11(i) (such exchange ratio being hereinafter referred to as
the "Exchange Ratio"). Notwithstanding the foregoing, the Board of Directors of
the Company shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange. The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the Common Shares for Rights will be effected,
and, in the event of any partial exchange, the number of Rights which will be
exchanged. Any partial exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void pursuant to the provisions
of Section 11(a)(ii) hereof) held by each holder of Rights.

         (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with this Section 24, the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exchange of the Rights. In the event the Company shall, after
good faith effort, be unable to take all such action as may be necessary to
authorize such additional Common Shares, the Company shall substitute, for each
Common Share that would otherwise be issuable upon exchange of a Right, a number
of Preferred Shares

                                      -22-
<PAGE>   26

or fraction thereof such that the current per share market price of one
Preferred Share multiplied by such number or fraction is equal to the current
per share market price of one Common Share as of the date of issuance of such
Preferred Shares or fraction thereof.

         (d) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional Common Shares, the Company shall pay to the registered
holders of the Right Certificates with regard to which such fractional Common
Shares would otherwise be issuable an amount in cash equal to the same fraction
of the current market value of a whole Common Share. For the purposes of this
paragraph (d), the current market value of a whole Common Share shall be the
closing price of a Common Share (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

         Section 25. Notice of Certain Events. (a) In case the Company shall, at
any time after the Distribution Date, propose (i) to pay any dividend payable in
stock of any class to the holders of the Preferred Shares or to make any other
distribution to the holders of the Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of the Preferred Shares
rights or warrants to subscribe for or to purchase any additional Preferred
Shares or shares of stock of any class or any other securities, rights or
options, (iii) to effect any reclassification of the Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the Common Shares and/or Preferred
Shares, if any such date is to be fixed, and such notice shall be so given in
the case of any action covered by clause (i) or (ii) above at least 10 days
prior to the record date for determining holders of the Preferred Shares for
purposes of such action, and, in the case of any such other action, at least 10
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier.

         (b) In case the event set forth in Section 11(a)(ii) hereof shall
occur, then the Company shall, as soon as practicable thereafter, give to each
holder of a Right Certificate, in accordance with Section 26 hereof, a notice of
the occurrence of such event, which notice shall describe such event and the
consequences of such event to holders of Rights under Section 11(a)(ii) hereof.

         Section 26. Notices. Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Right Certificate
to or on the Company shall be sufficiently given or made if sent by first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

Subject to the provisions of Section 21 hereof, any notice or demand authorized
by this Agreement to be given or made by the Company or by the holder of any
Right Certificate to or on the Rights Agent shall be sufficiently given or made

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Right Certificate shall be
sufficiently given or made if sent by first-class mail, postage prepaid,
addressed to such holder at the address of such holder as shown on the registry

         Section 27. Supplements and Amendments. The Company may from time to
time supplement or amend this Agreement without the approval of any holders of
Right Certificates in order to cure any ambiguity, to correct or supplement any
provision contained herein which may be defective or inconsistent with any other
provisions herein, or to make any other provisions with respect to the Rights
which the Company may deem necessary or desirable, any such supplement or
amendment to be evidenced by a writing signed by the Company and the Rights
Agent; provided, however, that, from and after such time as any Person becomes
an Acquiring Person, this Agreement shall not be amended in any manner which
would adversely affect the interests of the holders of Rights. Without limiting
the foregoing, the Company may at any time prior to such time as any Person
becomes an Acquiring Person amend this Agreement to lower the thresholds set
forth in Section 1(a) and 3(a) hereof to not less than 10% (the "Reduced
Threshold"); provided, however, that no Person who beneficially owns a number of
Common Shares equal to or greater than the Reduced Threshold shall become an
Acquiring Person unless such Person shall, after the public announcement of the
Reduced Threshold, increase its beneficial ownership of the then outstanding
Common Shares (other than as a result of an acquisition of Common Shares by the
Company) to an amount equal to or greater than the greater of (x) the Reduced
Threshold or (y) the sum of (i) the lowest beneficial ownership of such Person
as a percentage of the outstanding Common Shares as of any date on or after the
date of the public announcement of such Reduced Threshold plus (ii) .001%. Prior
to the time DoCoMo or any of its Standstill Affiliates becomes an Acquiring
Person, the Company shall not adopt any

                                      -24-
<PAGE>   28

amendment or supplement to this Agreement that would have the effect of causing
DoCoMo or any of its standstill Affiliates to be, without any action on the part
of DoCoMo or such Standstill Affiliate, an Acquiring Person.

         Section 28. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

         Section 29. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Shares) any legal or equitable right, remedy or claim under
this Agreement; but this Agreement shall be for the sole and exclusive benefit

                          AT&T WIRELESS SERVICES, INC.

                         (Pursuant to Section 151 of the
                        Delaware General Corporation Law)

                          AT&T Wireless Services, Inc.

         AT&T Wireless Services, Inc., a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Corporation"), hereby certifies that the following resolution was adopted
by the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on June 8, 2001:

         RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, par value $.01 per share, of the Corporation (the "Preferred Stock"), and
hereby states the designation and number of shares, and fixes the relative
rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be [ ]. Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

         Section 2. Dividends and Distributions.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Series A Preferred Stock

                                      A-1
<PAGE>   31

with respect to dividends, the holders of shares of Series A Preferred Stock, in
preference to the holders of Common Stock, par value $.01 per share (the "Common
Stock"), of the Corporation, and of any other junior stock, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the first day
of March, June, September and December in each year (each such date being
referred to herein as a "Quarterly Dividend Payment Date"), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $1 or (b) subject to the
provision for adjustment hereinafter set forth, 100 times the aggregate per
share amount of all cash dividends, and 100 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions, other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock since the immediately preceding Quarterly Dividend Payment Date or,
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Preferred Stock. In the
event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          (B) The Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in the event no dividend or distribution shall have been declared on
     the Common Stock during the period between any Quarterly Dividend Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $1 per share on the Series A Preferred Stock shall nevertheless be payable
     on such subsequent Quarterly Dividend Payment Date.

          (C) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
     dividends shall not bear interest. Dividends paid on

                                      A-2
<PAGE>   32

     the shares of Series A Preferred Stock in an amount less than the total
     amount of such dividends at the time accrued and payable on such shares
     shall be allocated pro rata on a share-by-share basis among all such shares
     at the time outstanding. The Board of Directors may fix a record date for
     the determination of holders of shares of Series A Preferred Stock entitled
     to receive payment of a dividend or distribution declared thereon, which
     record date shall be not more than 60 days prior to the date fixed for the
     payment thereof.

         Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of the stockholders of the
     Corporation. In the event the Corporation shall at any time declare or pay
     any dividend on the Common Stock payable in shares of Common Stock, or
     effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

          (B) Except as otherwise provided herein, in any other Certificate of
     Designations creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A Preferred Stock and the holders
     of shares of Common Stock and any other capital stock of the Corporation
     having general voting rights shall vote together as one class on all
     matters submitted to a vote of stockholders of the Corporation.

          (C) Except as set forth herein, or as otherwise provided by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

Section 4.  Certain Restrictions.

          (A) Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Preferred Stock as provided in Section 2 are in
     arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Series A Preferred
     Stock outstanding shall have been paid in full, the Corporation shall not:

               (i) declare or pay dividends, or make any other distributions, on
          any shares of stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock;

                                      A-3
<PAGE>   33

               (ii) declare or pay dividends, or make any other distributions,
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A
          Preferred Stock, except dividends paid ratably on the Series A
          Preferred Stock and all such parity stock on which dividends are
          payable or in arrears in proportion to the total amounts to which the
          holders of all such shares are then entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
          shares of any stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock, provided that the Corporation may at any time redeem, purchase
          or otherwise acquire shares of any such junior stock in exchange for
          shares of any stock of the Corporation ranking junior (either as to
          dividends or upon dissolution, liquidation or winding up) to the
          Series A Preferred Stock; or

               (iv) redeem or purchase or otherwise acquire for consideration
          any shares of Series A Preferred Stock, or any shares of stock ranking
          on a parity with the Series A Preferred Stock, except in accordance
          with a purchase offer made in writing or by publication (as determined
          by the Board of Directors) to all holders of such shares upon such
          terms as the Board of Directors, after consideration of the respective
          annual dividend rates and other relative rights and preferences of the
          respective series and classes, shall determine in good faith will
          result in fair and equitable treatment among the respective series or
          classes.

          (B) The Corporation shall not permit any subsidiary of the Corporation
     to purchase or otherwise acquire for consideration any shares of stock of
     the Corporation unless the Corporation could, under paragraph (A) of this
     Section 4, purchase or otherwise acquire such shares at such time and in
     such manner.

         Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

         Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $100.00 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquida-

                                      A-4
<PAGE>   34

tion, dissolution or winding up) with the Series A Preferred Stock, except
distributions made ratably on the Series A Preferred Stock and all such parity
stock in proportion to the total amounts to which the holders of all such shares
are entitled upon such liquidation, dissolution or winding up. In the event the
Corporation shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under the proviso in clause (1) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         Section 7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 8. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

         Section 9. Rank. The Series A Preferred Stock shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all series
of any other class of the Corporation's Preferred Stock.

         Section 10. Amendment. The Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

Introduction

         One preferred share purchase right (a "Right") is attached to and
trades each outstanding share of common stock, par value $.01 per share.

         Our Board has adopted the Rights Agreement that provides for these
rights in order to protect stockholders from coercive or otherwise unfair
takeover tactics. In general terms, it works by imposing a significant penalty
upon any person or group which acquires 15% or more of our outstanding common
stock without the approval of our Board. The Rights Agreement should not
interfere with any merger or other business combination approved by our Board.

         For those interested in the specific terms of the Rights Agreement as
made between our Company and Equiserve Trust Company, N.A., as the Rights Agent,
as of June 18, 2001, we provide the following summary description. Please note,
however, that this description is only a summary, and is not complete, and
should be read together with the entire Rights Agreement, which has been filed
with the Securities and Exchange Commission as an exhibit to a Registration
Statement on Form 8-A dated _________ __, 2001. A copy of the agreement is
available free of charge from our Company.

The Rights. The Rights trade with, and are inseparable from, the common stock.
The Rights are evidenced only by certificates that represent shares of common
stock. New Rights will accompany any new shares of common stock we issue until
the Distribution Date described below.

Exercise Price. Each Right will allow its holder to purchase from our Company
one one-hundredth of a share of Series A Junior Participating Preferred Stock
("Preferred Share") for $100.00, once the Rights become exercisable. This
portion of a Preferred Share will give the stockholder approximately the same
dividend, voting, and liquidation rights as would one share of common stock.
Prior to exercise, the Right does not give its holder any dividend, voting, or
liquidation rights.

Exercisability.  The Rights will not be exercisable until

-    10 days after the public announcement that a person or group has become an
     "Acquiring Person" by obtaining beneficial ownership of 15% or more of our
     outstanding common stock, or, if earlier,

-    10 business days (or a later date determined by our Board before any person
     or group becomes an Acquiring Person) after a person or group begins a
     tender or exchange offer which, if completed, would result in that person
     or group becoming an Acquiring Person.

         We refer to the date when the Rights become exercisable as the
"Distribution Date." Until that date, the common stock certificates will also
evidence the Rights, and any transfer of shares of common stock will constitute
a transfer of Rights. After that date, the Rights will separate from the common
stock and be evidenced by book-entry credits or by Rights

                                      C-1
<PAGE>   42

certificates that we will mail to all eligible holders of common stock. Any
Rights held by an Acquiring Person are void and may not be exercised.

         Our Board may reduce the threshold at which a person or group becomes
an Acquiring Person from 15% to not less than 10% of the outstanding common
stock.

Consequences of a Person or Group Becoming an Acquiring Person.

-    Flip In. If a person or group becomes an Acquiring Person, all holders of
     Rights except the Acquiring Person may, for $100.00, purchase shares of our
     common stock with a market value of $200.00, based on the market price of
     the common stock prior to such acquisition.

-    Flip Over. If our Company is later acquired in a merger or similar
     transaction after the Rights Distribution Date, all holders of Rights
     except the Acquiring Person may, for $100.00, purchase shares of the
     acquiring corporation with a market value of $200.00 based on the market
     price of the acquiring corporation's stock, prior to such merger.

Preferred Share Provisions.

Each one one-hundredth of a Preferred Share, if issued:

-    will not be redeemable.

-    will entitle holders to quarterly dividend payments of $.01 per share, or
     an amount equal to the dividend paid on one share of common stock,
     whichever is greater.

-    will entitle holders upon liquidation either to receive $1 per share or an
     amount equal to the payment made on one share of common stock, whichever is
     greater.

-    will have the same voting power as one share of common stock.

-    if shares of our common stock are exchanged via merger, consolidation, or a
     similar transaction, will entitle holders to a per share payment equal to
     the payment made on one share of common stock.

The value of one one-hundredth interest in a Preferred Share should approximate
the value of one share of common stock.

Expiration.  The Rights will expire on July 9, 2010.

Redemption. Our Board may redeem the Rights for $.01 per Right at any time
before any person or group becomes an Acquiring Person. If our Board redeems any
Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only
right of the holders of Rights will be to receive the redemption price of $.01
per Right. The redemption price will be adjusted if we have a stock split or
stock dividends of our common stock.

Exchange. After a person or group becomes an Acquiring Person, but before an
Acquiring Person owns 50% or more of our outstanding common stock, our Board may
extinguish the Rights

                                      C-2
<PAGE>   43

by exchanging one share of common stock or an equivalent security for each
Right, other than Rights held by the Acquiring Person.

Anti-Dilution Provisions. Our Board may adjust the purchase price of the
Preferred Shares, the number of Preferred Shares issuable and the number of
outstanding Rights to prevent dilution that may occur from a stock dividend, a
stock split, a reclassification of the Preferred Shares or common stock. No
adjustments to the Exercise Price of less than 1% will be made.

Amendments. The terms of the Rights Agreement may be amended by our Board
without the consent of the holders of the Rights. However, our Board may not
amend the Rights Agreement to lower the threshold at which a person or group
becomes an Acquiring Person to below 10% of our outstanding common stock. In
addition, the Board may not cause a person or group to become an Acquiring
Person by lowering this threshold below the percentage interest that such person
or group already owns. After a person or group becomes an Acquiring Person, our
Board may not amend the agreement in a way that adversely affects holders of the
Rights.<PAGE>   1

            REGISTRATION RIGHTS AGREEMENT, dated as of June 7, 2001, by and

advisable the separation of the Wireless Group (as defined in AT&T's amended and
restated certificate of incorporation (the "AT&T Charter")) from AT&T (the
"Separation");

            WHEREAS, to effect the Separation, all the then issued and
outstanding shares of AT&T Wireless Group Common Stock will be redeemed in
exchange for shares of common stock of Wireless ("Wireless Common Stock") in
accordance with the AT&T Charter, and a portion of AT&T's remaining interest in
Wireless will be distributed pro rata (the "Distribution") to holders of shares
of AT&T's Common Stock, par value $1.00 per share;

            WHEREAS, following the Distribution, AT&T will retain a number of
shares of Wireless Common Stock equal to $3 billion divided by the closing share
price of shares of AT&T Wireless Group tracking stock on the New York Stock
Exchange under the symbol "AWE" on the record date for determining holders of
AT&T common stock entitled to receive the Distribution (without giving effect to
any extended-hours trading) (the "Shares");

            WHEREAS, in connection with the Separation and Distribution,
Wireless has agreed to grant certain registration rights to AT&T in respect of
the Shares, on the terms and subject to the conditions set forth herein;

            NOW, THEREFORE, in consideration of the mutual covenants contained

      of all or part of the Registrable Securities held by AT&T; on Form S-1 or

      Long-Form Registration or Short-Form Registration shall specify the
      approximate number of Registrable Securities requested to be registered

      Registrations."

                                       2
<PAGE>   3
      (b)   Demand Registrations.

            (i) Number. AT&T shall be entitled to request up to two Demand
          Registrations with respect to the Registrable Securities held by AT&T.
          A registration will not count as a Demand Registration hereunder until
          such registration has become effective and unless AT&T is able to
          register at least 50% of the Registrable Securities requested to be
          included in such registration. AT&T may withdraw any request for
          registration prior to the time the registration statement is declared
          effective and in such event that registration will not be counted as a
          Demand Registration for purposes hereof. In addition, the registration
          of Shares contemplated by the Registration Statement filed with the
          SEC on May 8, 2001 (the "Debt for Equity Registration") shall not be
          included in determining the number of permitted registrations
          hereunder so long as such registration is effected substantially as
          contemplated by the Debt for Equity Registration Statement (including
          any amendment thereto) that has been filed as of the date of this
          Agreement. Wireless agrees to cooperate in connection with the
          transactions contemplated by the Debt for Equity Registration and to
          use all reasonable efforts to permit the issuance and sale of the
          securities registered thereunder.

            (ii) Suspension Period. With respect to any Demand Registration,
          Wireless shall be entitled not to file a registration statement, or if
          a registration has been filed, to cause such registration statement to
          be withdrawn and/or the effectiveness of such registration statement
          terminated, for a period not to exceed 90 days in any three-month
          period or for three periods not to exceed an aggregate of 150 days in
          any twelve-month period (each, a "Suspension Period") for valid
          business reasons, to be determined by Wireless in its sole reasonable
          judgment, including, without limitation, the acquisition or
          divestiture of assets, financings, public filings with the SEC,
          pending corporate developments and similar events. Wireless shall
          provide notice of any Suspension Period to AT&T. The foregoing
          notwithstanding, with respect to one Demand Registration only, if AT&T
          makes a request for such Demand Registration during the period from
          October 15, 2001 through January 15, 2002, Wireless shall not have the
          right under this paragraph (ii) to invoke a Suspension Period and
          accordingly to withdraw or terminate such registration or to not file
          such registration statement during the period from and including
          November 1, 2001 through and including January 31, 2002 (the
          "No-Black-Out Period") and, with respect to any Registrable Securities
          subject to such Demand Registration made during such period, clauses
          (iii) and (v) of the definition of Registrable Securities shall not
          apply.

            (iii) Registration Expenses.  AT&T shall pay, reimburse and
          indemnify Wireless for all Registration Expenses.

      (c) Short-Form Registrations. Demand Registrations will be Short-Form
      Registrations whenever Wireless is permitted to use any applicable short
      form. After Wireless has become subject to the reporting requirements of
      the Exchange Act, Wireless will use all reasonable efforts to make
      Short-Form Registration available for the sale of Registrable Securities.

                                       3
<PAGE>   4
      (d) Priority on Demand Registrations. Wireless will not include in any
      Long-Form Registration or Short-Form Registration regarding Registrable
      Securities any securities that are not Registrable Securities without the
      prior written consent of AT&T. If a Long-Form Registration or a Short-Form
      Registration regarding Registrable Securities is an underwritten offering
      and the lead managing underwriter advises Wireless in writing (with a copy
      to AT&T) that, in the opinion of such lead managing underwriter, the
      number or class of Registrable Securities and, if permitted hereunder,
      other securities requested to be included in such offering, exceeds the
      number or class of Registrable Securities and other securities, if any,
      which can be sold therein without adversely affecting the marketability of
      the offering, Wireless will exclude from such registration (i) first, any
      securities that are not Registrable Securities and (ii) second,
      Registrable Securities.

      (e) Selection of Underwriters. In the case of a Demand Registration for an
      underwritten offering made pursuant to the terms and conditions of this
      Agreement by AT&T, AT&T shall have the right to select the lead managing
      underwriter for such offering, subject to Wireless's consent, which shall
      not be unreasonably withheld.

      (f) 415 Registrations. If required in connection with the issuance or sale
      of any Convertible Securities, AT&T will be entitled to request a
      registration pursuant to Rule 415 under the Securities Act, to the extent
      required in connection with such Convertible Securities (a "415
      Registration"). As promptly as practicable and in any event within 30 days
      after Wireless receives written notice of a request for a 415
      Registration, Wireless shall file with the SEC a registration statement
      under the Securities Act for the 415 Registration. Wireless shall use all
      reasonable efforts to cause the 415 Registration to be declared effective
      under the Securities Act as soon as practical after filing and, once
      effective, Wireless shall (subject to the provisions of clause (ii) below)
      cause such 415 Registration to remain effective for such time period as is
      specified in such request, but for no time period longer than the period
      ending on the earlier of (i) the three month and one day anniversary of
      the Separation, or (ii) the date on which all Registrable Securities have
      been sold pursuant to the 415 Registration.

3.    Holdback Agreements.

      (a) Wireless agrees (i) not to effect any public sale or distribution of
      its equity securities, or any securities convertible into or exchangeable
      or exercisable for such securities, during the seven days prior to and
      during the 90-day period beginning on the effective date of any
      underwritten Demand Registration (including any 415 Registration relating
      to Convertible Securities) (except as part of such underwritten
      registration or pursuant to registrations on Forms S-4 or S-8 or any
      successor forms); and (ii) except with the prior written consent of AT&T,
      such consent not to be withheld unless AT&T intends to, or in good faith
      believes that it is reasonably likely to, request a Demand Registration
      that could reasonably be expected to be in registration or become
      effective during the No-Black-Out Period, to not file during the
      No-Black-Out Period any registration statement (except as part of a Demand
      Registration or pursuant to registrations on Forms S-4 or S-8 or any
      successor forms) relating to the public sale or distribution of its equity
      securities, or any securities convertible into or exchangeable or

                                       4
<PAGE>   5
      exercisable for such securities, and to withdraw and terminate any such
      registration statement as may have been filed or be in effect as of
      November 1, 2001 with respect to which the securities registered
      thereunder have not been sold.

4. Registration Procedures. In connection with the Debt for Equity Registration
and whenever a Demand Registration has been requested pursuant to this
Agreement, Wireless will use all reasonable efforts to effect the registration
and the sale of such Registrable Securities in accordance with the intended
method of disposition thereof, and pursuant thereto Wireless will as
expeditiously as possible:

      (a) prepare and file with the SEC a registration statement with respect to
      such Registrable Securities as promptly as practicable and in any event
      within 30 days of the request and use all reasonable efforts to cause such
      registration statement to become effective;

      (b) prepare and file with the SEC such amendments and supplements to such
      registration statement and the prospectus used in connection therewith as
      may be necessary to keep such registration statement effective for a
      period of not less than 30 days (or such other period as may be applicable
      pursuant to this Agreement in accordance with any 415 Registration) and
      comply with the provisions of the Securities Act with respect to the
      disposition of all securities covered by such registration statement
      during such period in accordance with the intended methods of disposition
      by AT&T set forth in such registration statement;

      (c) furnish to AT&T such number of copies of such registration statement,
      each amendment and supplement thereto, the prospectus included in such
      registration statement (including each preliminary prospectus) and such
      other documents as AT&T may request in order to facilitate the disposition
      of the Registrable Securities owned by AT&T;

      (d) use all reasonable efforts to register or qualify such Registrable
      Securities under such other securities or blue sky laws of such
      jurisdictions as AT&T reasonably requests and do any and all other acts
      and things which may be reasonably necessary or advisable to enable AT&T
      to consummate the disposition in such jurisdictions of the Registrable
      Securities owned by AT&T; provided, that Wireless will not be required to
      (i) qualify generally to do business in any jurisdiction where it would
      not otherwise be required to qualify but for this subsection, (ii) subject
      itself to taxation in any such jurisdiction, or (iii) consent to general
      service of process (i.e., service of process which is not limited solely
      to securities law violations) in any such jurisdiction;

      (e) notify AT&T at any time when a prospectus relating to Registrable
      Securities is required to be delivered under the Securities Act, of the
      happening of any event as a result of which the prospectus included in
      such registration statement contains an untrue statement of a material
      fact or omits any material fact necessary to make the statements therein
      not misleading, and, at the request of AT&T, Wireless will promptly
      prepare a supplement or amendment to such prospectus so that, as
      thereafter delivered to the purchasers of such Registrable Securities,
      such prospectus will not contain an untrue

                                       5
<PAGE>   6
      statement of a material fact or omit to state any material fact necessary
      to make the statements therein not misleading;

      (f) notify AT&T (A) when the prospectus or any prospectus supplement or
      post-effective amendment included in such registration statement has been
      filed, and, with respect to any registration statement or any
      post-effective amendment thereto, when the same has become effective, (B)
      of any request by the SEC for amendments to such registration statement or
      amendments or supplements to the prospectus or for additional information
      relating thereto, and (C) of the issuance by the SEC of any stop order
      suspending the effectiveness of the registration statement under the
      Securities Act or of the suspension by any state securities commission of
      the qualification of such Registrable Securities, as applicable, for
      offering or sale in any jurisdiction, or the initiation of any proceeding
      for any of the preceding purposes;

      (g) cause all such Registrable Securities to be listed on each securities
      exchange on which similar securities issued by Wireless are then listed;

      (h) provide a transfer agent and registrar for all such Registrable
      Securities not later than the effective date of such registration
      statement;

      (i) enter into such customary agreements (including underwriting
      agreements containing such representations and warranties by Wireless and
      such other terms, including indemnity, as are customarily contained in
      underwriting agreements entered into by AT&T with respect to underwritten
      offerings of AT&T securities of this type) and take all such other actions
      as the underwriters, if any, reasonably request in order to expedite or
      facilitate the disposition of such Registrable Securities;

      (j) make available for inspection by AT&T, any underwriter participating
      in any disposition pursuant to such registration statement and any
      attorney, accountant or other agent retained by AT&T or any underwriter,
      all financial and other records, pertinent corporate documents and
      properties of Wireless, and cause the managers, officers, members,
      employees and independent accountants of Wireless to supply all
      information reasonably requested by AT&T, any underwriter, attorney,
      accountant or agent in connection with such registration statement;

      (k) otherwise use all reasonable efforts to comply with all applicable
      rules and regulations of the SEC, and make available to its security
      holders, as soon as reasonably practicable, an earnings statement covering
      the period of at least twelve months beginning with the first day of the
      first full calendar quarter of Wireless after the effective date of the
      registration statement, which earnings statement shall satisfy the
      provisions of Section 11(a) of the Securities Act and Rule 158 promulgated
      thereunder;

      (l) in the event of the issuance of any stop order suspending the
      effectiveness of a registration statement, or of any order suspending or
      preventing the use of any related prospectus or suspending the
      qualification of any securities included in such registration statement
      for sale in any jurisdiction, Wireless will use all reasonable efforts
      promptly to obtain the withdrawal of such order;

                                       6
<PAGE>   7
      (m) use all reasonable efforts to cause such Registrable Securities
      covered by such registration statement to be registered with or approved
      by such other governmental agencies or authorities as may be necessary to
      enable AT&T to consummate the disposition of such Registrable Securities;

      (n) obtain a "cold comfort" letter from the independent public accountants
      of Wireless and opinions of counsel to Wireless in each case in customary
      form and covering such matters of the type customarily covered by "cold
      comfort" letters and opinions as AT&T reasonably requests; and

      (o)   otherwise facilitate such registration and related offering.

5.    Indemnification.

      (a) Wireless agrees to indemnify (i) AT&T, (ii) AT&T's officers,
      directors, agents, and representatives, and (iii) each Person who controls
      (within the meaning of the Securities Act) AT&T against all losses,
      claims, damages, liabilities, and expenses arising out of or based upon
      any untrue or alleged untrue statement of material fact contained in any
      registration statement, prospectus, or preliminary prospectus or any
      amendment thereof or supplement thereto or any omission or alleged
      omission of a material fact required to be stated therein or necessary to
      make the statements therein not misleading, and shall reimburse AT&T and
      such officers, directors, agents, and representatives, or controlling
      Person for any legal or other expenses reasonably incurred by AT&T and
      such officers, directors, agents, and representatives, or controlling
      Person in connection with the investigation or defense of such loss,
      claim, damage, liability or expense, except insofar as the same are caused
      by or contained in any information furnished in writing to Wireless by
      AT&T expressly for use therein or by AT&T's failure to deliver a copy of
      the registration statement or prospectus or any amendments or supplements
      thereto after Wireless has furnished AT&T with a sufficient number of
      copies of the same. In connection with an underwritten offering, Wireless
      will indemnify such underwriters, their officers, partners and directors,
      and each Person who controls such underwriters (within the meaning of the
      Securities Act) to the same extent as provided above with respect to the
      indemnification of AT&T.

      (b) AT&T will furnish to Wireless in writing such information as Wireless
      reasonably requests for use in connection with any registration statement
      or prospectus and will indemnify Wireless in connection with any
      registration of Registrable Securities, and its officers, directors,
      agents, and representatives and each Person who controls Wireless against
      any losses, claims, damages, liabilities and expenses resulting from any
      untrue or alleged untrue statement of material fact contained in such
      registration statement, prospectus or preliminary prospectus or any
      amendment thereof or supplement thereto or any omission or alleged
      omission of a material fact required to be stated therein or necessary to
      make the statements therein not misleading, but only to the extent that
      such untrue statement or omission is contained in any information or
      affidavit so furnished in writing by AT&T.

                                       7
<PAGE>   8
      (c) Any Person entitled to indemnification hereunder will (i) give prompt
      written notice to the indemnifying party of any claim with respect to
      which it seeks indemnification and (ii) unless in such indemnified party's
      reasonable judgment a conflict of interest between such indemnified and
      indemnifying parties may exist with respect to such claim, permit such
      indemnifying party to assume the defense of such claim with counsel
      reasonably satisfactory to the indemnified party. If such defense is
      assumed, the indemnifying party will not be subject to any liability for
      any settlement made by the indemnified party without its consent (but such
      consent will not be unreasonably withheld). An indemnifying party who is
      not entitled to, or elects not to, assume the defense of a claim will not
      be obligated to pay the fees and expenses of more than one counsel for all
      parties indemnified by such indemnifying party with respect to such claim,
      unless in the reasonable judgment of any indemnified party a conflict of
      interest may exist between such indemnified party and any other of such
      indemnified parties with respect to such claim.

      (d) The indemnification provided for under this Agreement will remain in
      full force and effect regardless of any investigation made by or on behalf
      of the indemnified party or any officers, directors, agents, and
      representatives, or controlling Person of such indemnified party and will
      survive the transfer of securities. Wireless, to the extent so liable,
      also agrees to make such provisions, as are reasonably requested by any
      indemnified party, for contribution to such party in the event the
      indemnification provided by Wireless pursuant to the terms and conditions
      of this Agreement is unavailable for any reason.

6. Rule 144 Reporting. With a view to making available to AT&T the benefits of
certain rules and regulations of the SEC which may permit the sale of the
Registrable Securities to the public without registration, Wireless agrees to
use all reasonable efforts to:

      (a) make and keep current public information available, within the meaning
      of Rule 144 or any similar or analogous rule promulgated under the
      Securities Act, at all times after it has become subject to the reporting
      requirements of the Exchange Act;

      (b) file with the SEC, in a timely manner, all reports and other documents
      required under the Securities Act and the Exchange Act (after Wireless has
      become subject to such reporting requirements); and

      (c) so long as any party hereto owns any Registrable Securities, furnish
      to such Person forthwith upon request a written statement as to the
      compliance by Wireless with the reporting requirements of said Rule 144
      (at any time commencing 90 days after the effective date of the first
      registration filed by Wireless for an offering of its securities to the
      general public), the Securities Act and the Exchange Act (at any time
      after it has become subject to such reporting requirements); a copy of its
      most recent annual or quarterly report; and such other reports and
      documents as such Person may reasonably request in availing itself of any
      rule or regulation of the SEC allowing it to sell any such securities
      without registration.

notices are to be given.

8. Debt for Equity Registration Exchange Agreement. Wireless agrees that it
will, promptly upon the request of AT&T, execute the Exchange Agreement and, as
and to the extent provided for therein, become a party thereto. The term
"Exchange Agreement" means an Exchange Agreement, between AT&T and one or more
purchasers of Shares from AT&T in connection with the Debt for Equity
Registration, substantially in the form provided to Wireless and to the Internal
Revenue Service prior to the date hereof, with such changes as do not affect
Wireless or such changes as do affect Wireless as to which Wireless consents,
such consent not to be withheld unreasonably.

9.    Miscellaneous.

            (a) Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

            (b) Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may be amended or waived only upon the prior
written consent of the parties hereto.

            (c) Successors and Assigns. Neither the rights nor the obligations
of any party may be assigned or delegated without the prior written consent of
the other party hereto; provided that, the foregoing notwithstanding, whether or
not any express assignment has been made, the provisions of this Agreement which
are for the benefit of AT&T are for the benefit of, and enforceable by AT&T on
behalf of, any subsequent holder of Registrable Securities that is at such time
a wholly-owned direct or indirect subsidiary of AT&T.

            (d) Severability. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision will be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

            (e) Counterparts. This Agreement may be executed simultaneously in
two or more counterparts, any one of which need not contain the signatures of
more than one party, but all such counterparts taken together will constitute
one and the same Agreement.

            (f)   Descriptive Headings.  The descriptive headings of this
Agreement are inserted for convenience only and do not constitute a part of
this Agreement.

            (g) GOVERNING LAW. ALL ISSUES AND QUESTIONS CONCERNING THE
APPLICATION, CONSTRUCTION, VALIDITY, INTERPRETATION AND ENFORCEMENT OF THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL
LAWS OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR

OTHER THAN THE STATE OF DELAWARE.
