       Group, and

     - other matters.

Statements in this document, or that are incorporated by reference into this
document, that are not historical facts are hereby identified as
"forward-looking statements" for the purpose of the safe harbor provided by
Section 21E of the Securities Exchange Act of 1934 and Section 27A of the
Securities Act of 1933. These forward-looking statements, including, without
limitation, those relating to the future business prospects, revenues, working
capital, liquidity, capital needs, network build out, interest costs and income,
in each case, relating to AT&T, AT&T Common Stock Group and AT&T Wireless Group,
wherever they occur in this document, are necessarily estimates reflecting the
best judgment of senior management and involve a number of risks and
uncertainties that could cause actual results to differ materially from those
suggested by the forward-looking statements. These forward-looking statements
should, therefore, be considered in light of various important factors,
including those set forth in this document. Important factors that could cause
actual results to differ materially from estimates or projections contained in
the forward-looking statements include, without limitation:

     - the risks associated with the implementation of a third generation
       network and business strategy, including risks relating to the operations
       of new systems and technologies, substantial required expenditures and
       potential unanticipated costs, the need to enter into roaming agreements
       with third parties, uncertainties regarding the adequacy of suppliers on
       whom these groups must rely to provide both network and consumer
       equipment and consumer acceptance of the products and services to be
       offered,

     - the potential impact of DoCoMo's strategic investment in AT&T Wireless
       Group, including provisions of the agreements that restrict AT&T Wireless
       Group's future operations, and provisions that may require AT&T to
       repurchase DoCoMo's interest in AT&T Wireless Group if AT&T or AT&T
       Wireless Group fail to meet specified conditions,

     - the risks associated with the implementation of AT&T's restructuring
       plan, which is complicated and which involves a substantial number of
       different transactions, any or all of which may not occur as we currently
       intend, or which may not occur in the timeframe we currently expect,

     - the risks associated with each of AT&T's main business units, including
       AT&T Wireless Group, operating as an independent entity as opposed to as
       part of an integrated telecommunications provider following completion of
       AT&T's restructuring plan, including the inability of these groups to
       rely on the financial and operational resources of the combined company
       and these groups having to provide services that were previously provided
       by a different part of the combined company,

     - the impact of new competitors entering the markets in which these groups
       compete, including competitors which may offer less expensive products
       and services, desirable or innovative products, technological substitutes
       or be well-financed and have extensive resources,

     - the potential of oversupply of capacity resulting from excessive
       deployment of network capacity in the markets served by these groups,

     - the ongoing global and domestic trend towards consolidation in the
       telecommunications industry, which trend may have the effect of making
       the competitors of these entities larger and better financed and afford
       these competitors with extensive resources and greater geographic reach,
       allowing them to compete more effectively,

     - the effects of vigorous competition in the markets in which these groups
       operate,

     - the ability to enter into agreements to provide, and the cost of entering
       new markets necessary to provide, nationwide services,

     - the ability to establish a significant market presence in new geographic
       and service markets,

                                       iii
<PAGE>   6

     - the availability and cost of capital and the consequences of increased
       leverage,

     - the impact of any unusual items resulting from ongoing evaluations of the
       business strategies of these groups,

     - requirements imposed on these groups or latitude allowed to competitors
       by the FCC or state regulatory commissions under the Telecommunications
       Act of 1996 or other applicable laws and regulations,

     - the risks associated with the need to acquire additional spectrum for
       current and future services,

     - the risks associated with technological requirements and changes and
       other technological developments,

     - results of litigation filed or to be filed against these groups,

     - the possibility of one or more of the markets in which these groups
       compete being impacted by changes in political, economic or other
       factors, such as monetary policy, legal and regulatory changes or other
       external factors over which these groups have no control,

     - the risks related to AT&T's investments in Liberty Media Group and joint
       ventures, and

     - those factors listed under "Risk Factors."

The words "estimate," "project," "intend," "expect," "believe" and similar
expressions are intended to identify forward-looking statements. These
forward-looking statements are found at various places throughout this document
and throughout the other documents incorporated into this document by reference,
including, but not limited to, AT&T's 1999 Annual Report on Form 10-K, including
any amendments to the annual report. Readers are cautioned not to place undue
reliance on these forward-looking statements, which speak only as of the date of

to these forward-looking statements to reflect events or circumstances after the

   shareholders. We intend this exchange offer to allow AT&T and holders of AT&T
   common stock to more fully realize the economic value arising from our
   ownership of AT&T Wireless Group, and to permit the retirement of shares of
   AT&T common stock.

   In addition, this exchange offer will give holders of AT&T common stock that
   desire to increase their relative investment in AT&T Wireless Group the
   opportunity to do so in a convenient manner. Shareholders that have an
   unrealized gain on their shares of AT&T common stock would be able to
   increase their relative investment in AT&T Wireless Group in a manner
   generally free of U.S. federal income tax consequences.

Q. IS AT&T RECOMMENDING THAT SHAREHOLDERS TENDER THEIR SHARES OF AT&T COMMON
   STOCK?

A. No. AT&T is not making any recommendation one way or the other. You should
   carefully evaluate all the information contained in or incorporated into this
   document, consult your own advisors and make your own decision. The answer as
   to whether or not you should tender your shares of AT&T common stock may vary
   depending upon your investment objectives, financial position and
   requirements and any other relevant considerations.

Q. IS THIS EXCHANGE OFFER BEING USED TO SEPARATE AT&T WIRELESS GROUP FROM AT&T?

A. No. This exchange offer itself will not result in a separation of AT&T
   Wireless Group from AT&T. However, following completion of this exchange
   offer and subject to specified conditions, AT&T intends to separate, or
   spin-off, AT&T Wireless Group from AT&T. While we currently intend to
   complete the spin-off, we cannot assure you that the spin-off will occur.

   In addition, although AT&T has no current plans to do so, prior to completion
   of the spin-off, AT&T may seek to sell additional equity in AT&T Wireless
   Group. If any sale did occur, it would reduce the percentage of the equity
   interest in the AT&T Wireless Group available for distribution to holders of
   AT&T common stock in any spin-off.

Q. WHAT WOULD BE THE MECHANICS OF A SPIN-OFF?

A. We expect that the spin-off would be accomplished through the following
   steps, any or all of which may occur simultaneously:

   - We would transfer all of the assets and liabilities of AT&T Wireless Group
     to AT&T Wireless Services, Inc., a subsidiary of AT&T.

   - We would mandatorily exchange, in accordance with the provisions of AT&T's
     charter, all outstanding shares of AT&T Wireless Group tracking stock for
     shares of AT&T Wireless Services common stock.

   - We would distribute the remaining shares of AT&T Wireless Services common
     stock to holders of AT&T common stock on a pro rata basis.

Q. WHAT IS THE DOCOMO INVESTMENT?

A. On November 30, 2000, AT&T, AT&T Wireless Services and NTT DoCoMo, Inc., a
   Japanese wireless communications company, entered into a binding letter
   agreement in which DoCoMo agreed to invest approximately $9.8 billion for an
   approximate 16% economic interest in AT&T Wireless Group. The parties signed
   final agreements for this investment on December 20, 2000. As part of this
   investment, DoCoMo will also receive five-year warrants to purchase
   additional shares of AT&T Wireless Group tracking stock at $35 per share, and
   DoCoMo and AT&T Wireless Group will form
<PAGE>   8

   a strategic alliance to develop the next generation of mobile multimedia
   services on a global-standard, high-speed wireless network. AT&T has agreed,
   if DoCoMo so elects, to repurchase DoCoMo's interest in AT&T Wireless Group
   if AT&T does not complete the spin-off, substantially in the manner
   described, of AT&T Wireless Group by January 1, 2002, or by March 15, 2002 if
   AT&T is trying to obtain a tax ruling, or if AT&T Wireless Group fails to
   commence service using an agreed technology in at least 13 of the top 50
   domestic markets by June 30, 2004.

Q. WILL THE SHARES OF AT&T WIRELESS GROUP TRACKING STOCK ISSUED IN THIS EXCHANGE
   OFFER DILUTE THE EARNINGS PER SHARE ATTRIBUTABLE TO SHARES OF AT&T WIRELESS
   GROUP TRACKING STOCK CURRENTLY OUTSTANDING?

A. No. This exchange offer will not dilute the earnings per share attributable
   to shares of AT&T Wireless Group tracking stock.

Q. HOW WILL THIS EXCHANGE OFFER AFFECT ME?

A. This exchange offer will provide you with an opportunity to increase your
   interest in the financial performance of AT&T Wireless Group by exchanging
   your shares of AT&T common stock for shares of AT&T Wireless Group tracking
   stock. We expect this exchange to be generally free of any U.S. federal
   income tax consequences, except with respect to cash received in lieu of
   fractional shares. You may tender some, all or none of your shares of AT&T
   common stock in exchange for shares of AT&T Wireless Group tracking stock in
   this exchange offer, subject to proration. However, you will be affected by
   this exchange offer whether or not you tender any of your shares of AT&T
   common stock because AT&T Common Stock Group's retained inter-group interest
   in AT&T Wireless Group will decrease, and the number of outstanding shares of
   AT&T common stock will also decrease. AT&T Common Stock Group is what we call
   the assets, the economic value of which is represented by AT&T common stock.

Q. WHAT IS AT&T'S RESTRUCTURING PLAN?

A. Under AT&T's restructuring plan announced October 25, 2000, each of AT&T's
   major units would become a publicly traded company, represented by either a
   common stock or a tracking stock.

   Upon completion of all elements of AT&T's restructuring plan, AT&T Wireless,
   AT&T Business and AT&T Broadband would be represented by independent,
   asset-based common stocks. AT&T Consumer would be represented by a tracking
   stock of AT&T Business. Each of these four companies would be accountable to
   its own customers, capital markets, shareholders, employees and other
   constituencies that would be able to evaluate the performance of each of
   these companies against other comparable companies. We cannot assure you that
   any or all of the elements of AT&T's restructuring plan will occur as we
   currently expect or in the time frames that we currently contemplate. In
   addition, many of the details of AT&T's restructuring plan have not been
   determined and we cannot predict the impact of AT&T's restructuring plan on
   the value of AT&T common stock or AT&T Wireless Group tracking stock.

Q. HOW DOES A DECISION TO TENDER SHARES OF AT&T COMMON STOCK RELATE TO AT&T'S
   RESTRUCTURING PLAN?

A. If AT&T's restructuring plan is completed, holders of shares of AT&T common
   stock that retain their shares will eventually receive shares representing
   interests in each of AT&T's four major business units: AT&T Wireless, AT&T
   Business, AT&T Consumer and AT&T Broadband. To the extent that you tender
   your shares of AT&T common stock in this exchange offer, your relative
   interest in AT&T Wireless Group will be increased but your relative interest
   in the other AT&T business units will be decreased. In addition, you will not
   receive shares in the other AT&T business units as part of AT&T's
   restructuring plan for those shares of AT&T common stock you tender. Instead,
   you will only have the shares of AT&T Wireless Group tracking stock that you
   received in this exchange offer, which may later come to represent a direct
   interest in AT&T Wireless Services if the spin-off occurs.

   Conversely, all holders of shares of AT&T common stock would receive shares
   of AT&T Wireless Services if it becomes an independent company in the
   spin-off. Even if you do not tender any shares of AT&T common stock in this
   exchange offer, if you retain your shares of AT&T common stock you will
   receive some shares in AT&T Wireless Services at that time. However, your
   interest in AT&T Wireless Services would be smaller than it would be if your

                                        2
<PAGE>   9

   shares of AT&T common stock are tendered and accepted in this exchange offer.

We cannot predict what the relative value of the securities representing
interests in AT&T Wireless, AT&T Business, AT&T Broadband and AT&T Consumer will
be over time. As a result, we cannot assure you whether the securities you would
own if you tender your shares of AT&T common stock will be worth more or less at
any point in the future than the securities you would own if you do not tender
your shares of AT&T common stock.

Q. WILL AT&T PAY DIVIDENDS ON THE AT&T WIRELESS GROUP TRACKING STOCK?

A. We do not currently expect to pay dividends on AT&T Wireless Group tracking
   stock in the foreseeable future. We also do not expect that, for the
   foreseeable future, AT&T Wireless Services will pay dividends on its common
   stock following the spin-off.

Q. MAY I PARTICIPATE IN THIS EXCHANGE OFFER?

A. Anyone who holds shares of AT&T common stock may participate in this exchange
   offer if they validly tender their shares of AT&T common stock during the
   exchange offer period in a jurisdiction under the laws of which this exchange
   offer is permitted.

Q: IF THIS EXCHANGE OFFER IS FULLY SUBSCRIBED, HOW MUCH OF THE ECONOMIC INTEREST
   IN AT&T WIRELESS GROUP WILL THE OUTSTANDING AT&T WIRELESS GROUP TRACKING
   STOCK REPRESENT?

A: Approximately 16% of the economic interest in AT&T Wireless Group is
   represented by currently outstanding AT&T Wireless Group tracking stock. If
   this exchange offer is fully subscribed and completed, this percentage would
   increase to approximately   %. Conversely, AT&T Common Stock Group's retained
   inter-group interest in AT&T Wireless Group is currently approximately 84% of
   the economic value of AT&T Wireless Group. If this exchange offer is fully
   subscribed, AT&T Common Stock Group's retained inter-group interest would
   decrease to approximately   %, approximately   % assuming completion of
   DoCoMo's strategic investment in AT&T Wireless Group, or approximately   %,
   assuming the exercise by DoCoMo of warrants that it will receive in AT&T
   Wireless Group.

Q. HOW MANY SHARES OF AT&T WIRELESS GROUP TRACKING STOCK WILL I RECEIVE FOR EACH
   SHARE OF AT&T COMMON STOCK THAT I TENDER IN THIS EXCHANGE OFFER?

A. You will receive        shares of AT&T Wireless Group tracking stock for each
   share of AT&T common stock that you validly tender in this exchange offer
   that is accepted by AT&T. We sometimes refer to this number in this document
   as the "exchange ratio." If more than        shares of AT&T common stock are
   validly tendered in this exchange offer, AT&T will accept those shares for
   exchange on a pro rata basis, as described below. Shares of AT&T Wireless
   Group tracking stock issued in this exchange offer will be issued in
   book-entry form.

Q. WHEN DOES THIS EXCHANGE OFFER EXPIRE?

A. The exchange offer period and withdrawal rights will expire at 12:00
   midnight, New York City time, on      ,                     , 2001, unless
   AT&T extends this exchange offer. This date is   business days from
          , 2001, which is the date on which we commenced this exchange offer.
   We sometimes refer to this date and time, as it may be extended by us, in
   this document as the "expiration date." You must tender your shares of AT&T
   common stock so that they are received by the exchange agent prior to the
   expiration date if you wish to participate in this exchange offer.

Q. DOES THIS EXCHANGE OFFER INVOLVE A PREMIUM?

A. Based on the closing trading prices for shares of AT&T common stock and AT&T
   Wireless Group tracking stock on               ,        , the exchange ratio
   would result in a tendering shareholder receiving shares of AT&T Wireless
   Group tracking stock with a market value of      % of the market value of the
   shares of AT&T common stock tendered. However, the relative trading prices
   for AT&T Wireless Group tracking stock and AT&T common stock will fluctuate
   over the course of this exchange offer and any premium or discount that you
   might receive as a tendering shareholder will depend on the prices of shares
   of AT&T common stock and AT&T Wireless Group tracking stock at the time of
   the closing of this exchange offer. We cannot predict whether there will be a
   premium or a discount at the closing of this exchange offer, the amount of
   either, or the prices at which shares of AT&T Wireless Group

                                        3
<PAGE>   10

tracking stock or AT&T common stock will trade over time.

Q. ARE THERE ANY CONDITIONS TO AT&T'S OBLIGATION TO COMPLETE THIS EXCHANGE
   OFFER?

A. Yes. We do not have to complete this exchange offer unless all of the
   conditions outlined on pages 54 to 56 are satisfied. In particular, there is
   a condition that at least           shares of AT&T common stock must be
   tendered into this exchange offer. This means that we will not be obligated
   to complete this exchange offer unless at least           shares of AT&T
   common stock are tendered so that           shares of AT&T Wireless Group
   tracking stock, or      % of those offered in this exchange offer, can be
   exchanged. We sometimes refer to this condition in this document as the
   "minimum condition." AT&T may at any time waive any or all of the conditions
   to this exchange offer.

Q. WHAT HAPPENS IF THE MINIMUM CONDITION IS SATISFIED BUT FEWER THAN      SHARES
   OF AT&T COMMON STOCK ARE TENDERED?

A. If the minimum condition is satisfied but fewer than      shares of AT&T
   common stock and all of the other conditions to this exchange offer have been
   satisfied or waived, AT&T would be obligated to complete this exchange offer
   as described in this document. Under these circumstances, this exchange offer
   would not be fully subscribed and, as a result, we would issue fewer than
        shares of AT&T Wireless Group tracking stock.

Q. WHAT HAPPENS IF MORE THAN      SHARES OF AT&T COMMON STOCK ARE TENDERED?

A. If more than      shares of AT&T common stock are tendered in this exchange
   offer, all shares of AT&T common stock that are validly tendered will be
   accepted for exchange on a pro rata basis. However, tenders by persons that
   own odd-lots, or fewer than 100 shares of AT&T common stock as of the date we
   announce the exchange ratio, that tender all of the shares they own will not
   be subject to proration and those shares of AT&T common stock will be
   accepted in full. Shares of AT&T common stock you own in an AT&T savings plan
   are not eligible for the preferential treatment that odd-lot holders will
   receive. Proration will be based on the number of shares of AT&T common stock
   that each holder has tendered in this exchange offer, and not on that
   holder's aggregate ownership of AT&T common stock. Any shares of AT&T common
   stock not accepted for exchange as a result of proration will be returned to
   tendering holders in book-entry form.

Q. WHAT HAPPENS IF AT&T DECLARES A QUARTERLY DIVIDEND ON AT&T COMMON STOCK
   DURING THIS EXCHANGE OFFER AND I HAVE PREVIOUSLY TENDERED MY SHARES OF AT&T
   COMMON STOCK?

A. If a dividend is declared with a record date before the completion of this
   exchange offer, you will be entitled to that dividend even if you have
   previously tendered your shares of AT&T common stock. Tendering your shares
   of AT&T common stock in this exchange offer is not a sale or transfer of
   those shares until they are accepted by AT&T for exchange upon completion of
   this exchange offer.

Q. HOW CAN I GET MORE INFORMATION ABOUT THIS EXCHANGE OFFER?

A. Please see the sections entitled "Summary -- Terms of this Exchange Offer" on
   page 9 and "This Exchange Offer" on page 46. You may call the information
   agent, Georgeson Shareholder Services, to ask any questions or to request
   additional documents at (     )           (toll free) in the United States or

                                    SUMMARY

     This summary highlights only selected information from this document and
may not contain all of the information that is important to you. To better
understand this exchange offer, you should read this entire document and the
accompanying letter of transmittal carefully, as well as those additional
documents to which we refer you. See "Where You Can Find More Information" on

                                    OVERVIEW

     Subject to the satisfaction of the conditions to this exchange offer, we
will issue           shares of AT&T Wireless Group tracking stock for each share
of AT&T common stock that is validly tendered and accepted by us in this
exchange offer, up to an aggregate of           shares of AT&T Wireless Group
tracking stock. We are making this exchange offer in connection with
implementing our plan to more widely distribute AT&T Wireless Group tracking
stock to our shareholders. This exchange offer is intended to allow AT&T and all
of our shareholders to more fully realize the economic value arising from our
ownership of AT&T Wireless Group, and to permit the retirement of shares of AT&T
common stock.

     Upon completion of this exchange offer, AT&T Wireless Group will remain a
part of AT&T. However, following completion of this exchange offer and subject
to specified conditions, AT&T intends to spin-off AT&T Wireless Group from AT&T.
These conditions include, among others, receipt of a favorable ruling on the
spin-off from the Internal Revenue Service, the satisfaction by AT&T of the
conditions in a new credit agreement that AT&T expects to enter into and the
receipt of other approvals.

     We expect that the spin-off would be accomplished through the following
steps, any or all of which may occur simultaneously. First, we would transfer
all of the assets and liabilities of AT&T Wireless Group to AT&T Wireless
Services, a subsidiary of AT&T that currently holds a substantial amount of the
assets of AT&T Wireless Group. We would then mandatorily exchange, in accordance
with terms of AT&T's charter, all outstanding shares of AT&T Wireless Group
tracking stock, including shares to be issued in this exchange offer and to
DoCoMo in exchange for the securities with respect to AT&T Wireless Group it
then holds, for shares of AT&T Wireless Services. Finally, we would distribute
the remaining shares of AT&T Wireless Services to holders of AT&T common stock,
on a pro rata basis. While we currently intend to complete the spin-off, we
cannot assure you that the conditions described will be met, or that even if the
conditions are met, that the spin-off will occur or that if the spin-off does
occur that it will occur on the terms or in the manner described, or in the time
frame contemplated.

     Although AT&T has no current plans to do so, prior to completion of the
spin-off, AT&T may seek to sell additional equity in AT&T Wireless Group. If any
sale did occur, it would reduce the percentage of the equity interest in AT&T
Wireless Group available for distribution to holders of AT&T common stock in any
spin-off.

     The proposed spin-off is an element of AT&T's restructuring plan announced
October 25, 2000. Under AT&T's restructuring plan, each of AT&T's major business
units is expected to become a publicly traded company, represented by either a
common stock or a tracking stock. AT&T shareholders that do not tender all of
their shares of AT&T common stock in this exchange offer and retain their shares
of AT&T common stock would ultimately own stock in four AT&T businesses: AT&T
Wireless, AT&T Business, AT&T Broadband and AT&T Consumer. Upon completion of
all elements of AT&T's restructuring plan, AT&T Wireless, AT&T Business and AT&T
Broadband would be represented by independent, asset-based common stocks. AT&T
Consumer would be represented by a tracking stock of AT&T Business. Each of
these four companies would be accountable to its own customers, capital markets,
shareholders, employees and other constituencies that would be able to evaluate
the performance of each of these companies against other comparable companies.
We cannot assure you however, that AT&T's restructuring plan will be completed,
or that if it is completed, it will be completed on the terms or in the manner
described, or in the time frame contemplated. In addition, many details of
AT&T's restructuring plan have not yet been determined, and we cannot predict
the impact that AT&T's restructuring plan will have on the value of AT&T common
stock and AT&T Wireless Group tracking stock.

                                      AT&T

     AT&T is among the world's communications leaders, providing voice, data and
video communications to large and small businesses, consumers and government
entities. AT&T and its subsidiaries furnish domestic and international long
distance, regional, local and wireless communications services, cable television
and Internet communications services. AT&T also provides billing, directory
assistance, and calling card services to support its communications business.

     AT&T's primary lines of business are business services, consumer services,
broadband services and wireless services. In addition, AT&T's other lines of
business include network management and professional services through AT&T
Solutions and international operations and ventures.

     On October 25, 2000, AT&T announced a restructuring plan to create four new
companies. On November 15, 2000, AT&T announced a plan to distribute ownership
of the Liberty Media Group to the holders of the Liberty Media Group tracking
stock in exchange for that tracking stock. AT&T has not yet determined the
precise structure or the timing of that transaction. The proposed distribution
is subject to receipt of a favorable tax ruling from the Internal Revenue
Service. We cannot assure you that the distribution of Liberty Media Group will
be completed or that changes in the distribution plan will not be made.

     The principal executive offices of AT&T are located at 32 Avenue of the

                              AT&T WIRELESS GROUP

     The AT&T Wireless Group is one of the largest wireless service providers in
the United States based on $7.5 billion in revenue for the nine months ended
September 30, 2000. Including its partnership markets, AT&T Wireless Group had
almost 15 million total subscribers as of September 30, 2000. AT&T Wireless
Group focuses on revenue growth through the retention and expansion of its
subscriber base. AT&T Wireless Group seeks to do this by providing new and
innovative services that distinguish it from its competitors. Examples include
pricing plans that simplify customer choice, such as AT&T Digital One Rate
service.

     AT&T Wireless Group operates one of the largest U.S. digital wireless
networks. AT&T Wireless Group, including its partnership and affiliate markets,
currently holds 850 megahertz and 1900 megahertz licenses to provide wireless
services covering 97% of the U.S. population, with approximately 79% of the U.S.
population covered by at least 30 megahertz of wireless spectrum as of September
30, 2000. As of September 30, 2000, AT&T Wireless Group's built network,
including partnership and affiliate markets, covered 73% of the U.S. population.
This includes operations in 48 of the 50 largest U.S. metropolitan areas. By the
end of 2000, AT&T Wireless Group expects that its built network, including
partnership and affiliate markets, will cover over 75% of the U.S. population.
AT&T Wireless Group supplements its own operations with roaming agreements that
allow its subscribers to use other providers' wireless services in regions where
AT&T Wireless Group does not have operations. Through these roaming agreements,
AT&T Wireless Group is able to offer its customers wireless services covering
over 95% of the U.S. population. AT&T Wireless Group plans to continue to
increase its coverage and the quality of its services by expanding the footprint
and capacity of its network at an increased pace and by acquiring or partnering
with other wireless providers.

     AT&T Wireless Group historically has provided its wireless voice and data
services using primarily time division multiple access, or TDMA, analog and
cellular digital packet data, or CDPD technologies. Recently AT&T Wireless Group
announced plans to deploy a global system for mobile communications, or GSM,
platform to facilitate the implementation of next generation technology. On the
same day, it was announced that AT&T and AT&T Wireless Services entered into a
binding letter agreement with DoCoMo, a Japanese wireless communications
company, for DoCoMo's investment in AT&T representing an economic interest in
AT&T Wireless Group and for the formation of a strategic alliance with AT&T
Wireless Group to develop the next generation of mobile multimedia services on a
global-standard, high-speed wireless network. The parties signed final
agreements for this investment on December 20, 2000.

     AT&T Wireless Group has focused on building out its digital network,
including upgrading its analog systems to digital in its 850 megahertz markets,
and on migrating its customers from analog to digital service. AT&T Wireless
Group believes that digitalization improves capital efficiency, lowers network
operating costs

                                        6
<PAGE>   13

and allows it to offer higher quality services. As of September 30, 2000, AT&T
Wireless Group had upgraded 99% of its 850 megahertz markets to digital based
systems and all of its 1900 megahertz markets are digital based. As of September
30, 2000, over 87% of AT&T Wireless Group's consolidated subscribers use digital
services, accounting for over 94% of its traffic. AT&T Wireless Group believes
that these percentages are substantially greater than the industry average,
excluding AT&T Wireless Group.

     AT&T Wireless Group markets its products and services primarily under the
AT&T brand name and expects to be able to continue to do so for some time,
pursuant to agreements expected to become effective in connection with the
proposed spin-off. AT&T Wireless Group believes that AT&T's widely recognized
brand increases consumer awareness of, and confidence in, AT&T Wireless Group's
products and services.

     AT&T Wireless Group has targeted two growth areas for near term expansion:
wireless data and fixed wireless. AT&T Wireless Group is an industry leader in
wireless data services, possessing a CDPD network covering markets with a total
population of 104 million. In addition to CDPD technology, AT&T Wireless Group
has announced plans to deploy GPRS and third generation technologies capable of
greater data speeds. AT&T Wireless Group expects new applications for corporate
and consumer use to further drive wireless data growth. These data applications
may include instant messaging, access to email, Internet content, e-commerce,
shopping services and services that are enhanced by information about the user's
location. In addition, AT&T Wireless Group has begun to deploy a fixed wireless
technology. AT&T Wireless Group believes there is a significant business
opportunity to use wireless technology to provide residential and small business
customers with high speed, "always on" broadband access coupled with wireline
quality voice access.

     AT&T Wireless Group is currently represented by a tracking stock designed
to reflect the separate economic performance of AT&T Wireless Group. Except as
described below, we attribute all of AT&T's current wireless operations to AT&T
Wireless Group, including:

     - all mobile and fixed wireless licenses,

     - all wireless networks, operations, cell sites, retail operations,
       wireless customer care facilities and customer location assets, and

     - interests in partnerships and affiliates providing wireless mobile
       communications in the United States and internationally.

     AT&T retains:

     - existing and future wireless activities that stem from country-specific
       joint venture relationships that are predominantly non-wireless, and

     - incidental wireless capabilities or links in any backbone or other
       communications network that is predominantly non-wireless.

     Prior to the spin-off, we currently intend to include all future wireless
activities in AT&T Wireless Group. Our board of directors may, however, in its
discretion, but subject to AT&T Wireless Group policy statement, direct new
businesses and assets to AT&T Wireless Group or to the rest of AT&T or dispose
of or transfer businesses or assets of either group. Following the spin-off, we
expect AT&T Wireless Group to own largely the same assets that were attributed
to AT&T Wireless Group prior to the spin-off.

     The principal executive offices of AT&T Wireless Group are located at 7277
164th Avenue NE, Building 1, Redmond, Washington 98052. The telephone number is
(425) 580-6000.

INDUSTRY OVERVIEW

     The growth in the wireless communications industry has been shaped by a
number of trends that are likely to continue in the near future. Key trends
include:

     - increased penetration, which is improving network efficiency,

     - rate simplification, which eases customer choice, increases penetration
       and leads to industry consolidation,

     - declining costs of service, which is leading to mass market availability
       of wireless communications,

     - increased use of digital service, as opposed to analog service, which is
       increasing the range of wireless service capabilities for subscribers,
       and

     - development of wireless data applications, which AT&T Wireless Group
       believes will increase wireless usage.

STRATEGY

     AT&T Wireless Group's goal is to be the premier provider of high-quality
wireless communications services, whether mobile or fixed, voice or data, to
businesses or consumers, in the United States or internationally. AT&T Wireless
Group believes that the following are key elements to enable it to meet its
goal:

     - continue expansion of its digital network to add capacity, improve
       quality and provide consistent features regardless of location,

     - continue to lower its operating costs and improve capital efficiency by
       expanding its digital mobile wireless network and increasing the use of
       more efficient channels of distribution,

     - deploy a GSM platform as the basis for implementation of third
       generation, or 3G, services, including GPRS, EDGE and, ultimately, UMTS,

     - target distinct consumer and business customer segments with wireless
       offers that match their needs for voice and data services, in order to
       increase its subscriber base and revenues,

     - take advantage of its relationship with AT&T, including the use of the
       AT&T brand and AT&T's distribution channels and cross marketing
       opportunities, and

     - take advantage of its existing wireless spectrum, digital network,
       customer base and the AT&T brand with new growth initiatives, including
       wireless data and fixed wireless opportunities.

     AT&T Wireless Group believes the following key strengths and assets
differentiate it from other wireless service providers:

     - Spectrum -- licenses, including partnership and affiliate markets,
       covering 97% of the U.S. population, with approximately 79% of the U.S.
       population covered by at least 30 megahertz of wireless spectrum,

     - Network -- operations in 48 of the 50 largest U.S. metropolitan areas,

     - Subscriber base -- almost 15 million, including partnership markets,

     - Brand -- benefits from AT&T's widely recognized brand which it expects to
       be able to continue to use for some time following the spin-off pursuant
       to agreements expected to become effective in connection with the
       spin-off,

     - Digital migration -- majority of subscribers migrated from analog to
       digital services, and

     - Management team -- experienced senior executives.

                           COMPARATIVE PER SHARE DATA

     We summarize in the tables below the historical and pro forma per share
information for AT&T Wireless Group tracking stock, or AWE stock, and for AT&T
common stock, or T stock. AT&T's historical book value per share was calculated
based on AT&T common stock, Liberty Media Group Class A common stock, Liberty
Media Group Class B common stock and AT&T Wireless Group tracking stock
outstanding and 1.95 billion assumed shares, which shares represent AT&T Common
Stock Group's retained inter-group interest in AT&T Wireless Group. In reading
the following information, you should note that the exchange ratio in this
exchange offer is      , and therefore that the per share data set forth below
does not set forth a comparison between the per share data for AT&T common stock
and the comparable data for the number of shares of AT&T Wireless Group tracking
stock you would receive in this exchange offer, in exchange for each share of
AT&T common stock. You should also note that on December 20, 2000, AT&T
announced that it had reduced the quarterly dividend on AT&T common stock to
$0.0375 per share. The Liberty Media Group loss per share data for the nine
months ended September 30, 1999 and year ended December 31, 1999 has been
restated to reflect a two-for-one stock split paid on June 9, 2000.

PRO FORMA PER SHARE DATA

     This pro forma per share information gives effect to a fully subscribed
exchange offer, the DoCoMo investment and the distribution of AT&T Wireless
Group as if such events had been completed on January 1, 1999 for income
statement purposes, and at September 30, 2000 for balance sheet purposes. The
pro forma per share information also gives effect to the TCI and MediaOne
mergers as if they had been completed on January 1, 1999 for income statement
purposes. As a result of this exchange offer, the earnings (loss) per share
calculation of AT&T common stock will reflect the lower number of outstanding
shares of AT&T common stock and the shareholders' decreased interest in the
available separate combined net income (loss) of AT&T Wireless Group. While
there will be no change to the earnings per share of AT&T Wireless Group
tracking stock as a result of the exchange offer, the earnings per share
calculation of AT&T Wireless Group tracking stock will reflect the shareholders'
increased interest in the available separate combined net income (loss) of AT&T
Wireless Group and the proportionate increase in the number of shares of AT&T
Wireless Group tracking stock outstanding.

information we incorporate by reference, see "Where You Can Find More
Information" on page 135.

AT&T CORP.

     In the table below, we provide you with selected historical consolidated
financial data of AT&T. We prepared this information using our consolidated
financial statements at and for each of the nine-month periods ended September
30, 2000, and September 30, 1999, and at and for each of the fiscal years in the
five-year period ended December 31, 1999. We derived the consolidated income
statement data below for each of the three years ended December 31, 1999, and
the consolidated balance sheet data at December 31, 1999 and 1998, from
consolidated financial statements audited by PricewaterhouseCoopers LLP,
independent accountants. We derived the remaining data from unaudited
consolidated financial statements.

     Income from continuing operations for the nine months ended September 30,
2000, includes $0.05 billion of a net benefit consisting primarily of gains on
the sale of businesses, restructuring and other charges and equity losses
associated with investments in Cablevision Systems Corporation and Time Warner
Entertainment. Income from continuing operations for the nine months ended
September 30, 1999, includes $0.5 billion of a net expense consisting primarily
of an in-process research and development charge associated with AT&T's merger
with Tele-Communications, Inc., or TCI, equity losses associated with an
investment in Cablevision, restructuring and other charges, and gains on the
sale of businesses.

     Income from continuing operations for the year ended December 31, 1999
includes $1.1 billion of a net expense consisting primarily of an in-process
research and development charge associated with our merger with TCI, equity
losses associated with an investment in Cablevision, an asset impairment charge
associated with the planned disposal of certain wireless network equipment,
other restructuring charges, and gains on the sale of businesses. Income from
continuing operations for the year ended December 31, 1998 includes $1.1 billion
of a net expense consisting of restructuring and other charges as well as
benefits from gains on the sales of businesses. Income from continuing
operations for 1995 includes $2.0 billion of a net expense consisting of
restructuring and other charges. The number of shares of Liberty Media Group
tracking stock outstanding and per share data reflect a two-for-one stock split
paid on June 9, 2000.

(1) On June 15, 2000, the MediaOne Group, Inc. merger closed. The MediaOne
    merger was recorded as a purchase. Accordingly, the results of operations of
    MediaOne have been included in AT&T's consolidated results since the date
    the merger closed.

(2) On March 9, 1999, the TCI merger closed. The TCI merger was recorded as a
    purchase. Accordingly, the results of operations of TCI and Liberty Media
    Group have been included in AT&T's consolidated results since the date the
    merger closed. In conjunction with the TCI merger, AT&T issued Liberty Media
    Group tracking stock to reflect the separate economic performance of the
    Liberty Media Group. AT&T does not have a "controlling financial interest"
    for financial accounting purposes in the Liberty Media Group, therefore AT&T
    accounts for the Liberty Media Group as an equity investment. Because the
    Liberty Media Group is reflected by separate tracking stock, AT&T excludes
    all of the earnings or losses related to the Liberty Media Group from the
    earnings available to the holders of AT&T common stock.

(3) Basic and diluted losses per share from continuing operations of Liberty
    Media Group tracking stock prior to the two-for-one stock split, for the
    nine months ended September 30, 1999 and for the year ended December 31,
    1999 were $0.65 and $1.61, respectively.

     The following information is only a summary and you should read it together

information we incorporate by reference, see "Where You Can Find More
Information" on page 135.

AT&T WIRELESS GROUP

     In the table below, we provide you with unaudited selected pro forma
condensed combined financial information of AT&T Wireless Group. The unaudited
pro forma condensed combined balance sheet set forth below as of September 30,
2000 for AT&T Wireless Group gives effect to (1) the DoCoMo transaction and (2)
the repayment of all intercompany amounts owed to AT&T with available funds,
including long-term debt and preferred stock outstanding as of September 30,
2000 as if such events had been completed on January 1, 1999. The unaudited pro
forma condensed statements of operations assume that AT&T Wireless Group had
incurred interest expense associated with an assumed amount of long-term debt
outstanding equal to the combined amount of intercompany long-term debt and
preferred stock held by AT&T for both the nine months ended September 30, 2000
and for the year ended December 31, 1999. AT&T Wireless Group has no commitments
related to future financing arrangements, however, interest expense has been
reflected on these intercompany amounts in the combined statements of operations
which is more reflective of AT&T Wireless Group results than presenting no
interest expense or preferred stock dividends for these periods.

     There is no impact to AT&T Wireless Group's combined financial statements
as a result of this exchange offer.

     We have included detailed unaudited pro forma combined financial statements
starting on page F-1 of this document.

                                  RISK FACTORS

     You should carefully consider each of the following risks and uncertainties
and all of the other information set forth in this document before deciding
whether to participate in this exchange offer.

     The risks and uncertainties described below are not the only ones relating
to this exchange offer, facing AT&T and AT&T Wireless Group or relating to any
investment in AT&T common stock or AT&T Wireless Group tracking stock. You
should carefully review the information set forth elsewhere in this document and
in the other documents which are incorporated by reference into this document.
Additional risks and uncertainties not presently known to us or that we
currently believe to be immaterial may also adversely affect AT&T, AT&T Wireless
Group and your investment in AT&T common stock or AT&T Wireless Group tracking
stock.

     If any of the following risks and uncertainties develop into actual events,
AT&T Wireless Group's business, financial condition, prospects or results of
operations could be materially adversely affected. In such case, the trading
price of AT&T Wireless Group tracking stock could decline materially.

     This document contains forward-looking statements that involve risks and
uncertainties. AT&T's and AT&T Wireless Group's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of a number of factors, including the risks and uncertainties faced by
AT&T and AT&T Wireless Group described below and elsewhere in this document.

RISK FACTORS RELATING TO AT&T'S RESTRUCTURING PLAN

     AT&T's restructuring plan, if completed, will result in fundamental changes
to AT&T and AT&T's businesses, including AT&T Wireless Group; we cannot predict
how the implementation of AT&T's restructuring plan will affect AT&T and its
businesses or the trading price of AT&T common stock and AT&T Wireless Group
tracking stock

     Although AT&T is currently involved in a number of businesses, including
those businesses the economic performance of which is currently represented by
AT&T common stock and AT&T Wireless Group tracking stock, historically, AT&T has
been one company. AT&T's restructuring plan announced October 25, 2000, if
completed, will result in fundamental changes to AT&T and AT&T's businesses. In
particular, if AT&T's restructuring plan is completed, holders of AT&T common
stock that do not tender all of those shares into this exchange offer or
otherwise dispose of those shares of AT&T common stock will eventually receive
shares representing interests in four separate businesses: AT&T Business, AT&T
Consumer, AT&T Broadband and AT&T Wireless. We cannot predict the trading prices
of these shares and we cannot assure you that the aggregate value of these
shares will exceed what the value of AT&T common stock would be without the
restructuring. We also cannot assure you that the trading price of AT&T common
stock will not decline as a result of the implementation of AT&T's restructuring
plan.

     Each of these companies will also be a new company, operating for the first
time as an independent entity, and the transition to independent operation will
require substantial effort and involve substantial risks and costs. If any of
these companies is unable to make this transition smoothly or if any of these
companies is not able to operate as effectively on a stand-alone basis, the
financial position and results of operations of that company could suffer, and
cause the trading value of that company's securities to decline. In addition,
following each separation the securities of each of these companies will begin
trading publicly for the first time. Until orderly trading markets develop for
each of these new securities, and after that time as well, there may be
significant fluctuations in price. Also, many of the details of AT&T's
restructuring plan have not been determined and we cannot predict the impact of
AT&T's restructuring plan on the value of AT&T common stock or AT&T Wireless
Group tracking stock.

     We cannot assure you that AT&T's restructuring plan will be completed as we
expect

     AT&T's restructuring plan is complicated, and involves a substantial number
of steps and transactions. The implementation of this restructuring plan will
require various approvals and be subject to various conditions. In addition,
circumstances may occur that make it inadvisable to proceed with part or all of
AT&T's restructuring plan. We also cannot assure you that implementation of the
restructuring plan will not

                                       21
<PAGE>   28

adversely affect the trading prices of AT&T common stock and/or AT&T Wireless
Group tracking stock. If we are unable to complete AT&T's restructuring plan as
we expect, or the implementation of AT&T's restructuring plan is more complex
than we expect, AT&T, its business or the trading prices of its securities may
be materially adversely affected. We cannot assure you that any or all of the
elements of AT&T's restructuring plan will occur as we currently expect or in
the time frames that we currently contemplate or at all.

     AT&T's failure to complete its restructuring plan as contemplated may
impact its liquidity

     At September 30, 2000, AT&T had current assets of $15.5 billion and current
liabilities of $51.3 billion. A significant portion of the current liabilities,
$32.3 billion, relate to short-term notes, the majority of which was commercial
paper or debt with an original maturity of one year or less. AT&T expects that
it will retire a portion of the short-term debt with funds that will be
generated from the expected mid-2001 initial public offering of AT&T Broadband
tracking stock. In addition, AT&T continues to investigate and negotiate other
financing alternatives including the monetization of publicly held securities,
sales of certain non-strategic assets and investments, securitization of certain
accounts receivable, and a potential separate debt offering by AT&T Wireless.
Since September 30, 2000, AT&T has monetized certain publicly held securities
through the issuance of approximately $1 billion of asset-backed debt. Lastly,
AT&T is presently in negotiations to increase its $10 billion line of credit to
$25 billion. At September 30, 2000, all of the $10 billion line of credit was
available for AT&T's use. There can be no assurance that AT&T will be able to
obtain financing on terms that are acceptable to it.

     AT&T's debt ratings have been under review by the applicable rating
agencies. As a result of this review, AT&T's ratings have been either downgraded
and/or put on credit watch with negative outlook. These actions will result in
an increased cost of future borrowings. AT&T's failure to complete the
restructuring plan as contemplated may impact its liquidity.

     Your decision to tender shares of AT&T common stock in this exchange offer
will change what you receive as part of AT&T's restructuring plan

     If AT&T's restructuring plan is completed as planned, holders of shares of
AT&T common stock who retain their shares of AT&T common stock will eventually
receive shares representing interests in AT&T Wireless, AT&T Business, AT&T
Broadband and AT&T Consumer. To the extent that your shares of AT&T common stock
are tendered and accepted in this exchange offer, your relative interest in AT&T
Wireless Group will be increased, your relative interest in the remaining AT&T
businesses will be decreased and you will not receive shares in AT&T Wireless,
AT&T Business, AT&T Broadband and AT&T Consumer for your shares of AT&T common
stock that you tender in this exchange offer.

     Conversely, all holders of shares of AT&T common stock are expected to
receive shares of AT&T Wireless Group in mid-2001 when it becomes an independent
company. Even if you do not tender any shares of AT&T common stock in this
exchange offer, if you retain your shares of AT&T common stock we expect that
you will receive some shares in AT&T Wireless Group at that time. However, your
interest in AT&T Wireless Group will be smaller than it would be if your shares
are tendered and accepted in this exchange offer.

     We cannot predict what the relative value of the shares representing
interests in AT&T Wireless, AT&T Business, AT&T Broadband and AT&T Consumer will
be over time. As a result, we cannot tell whether the securities you would own
if you tender shares of AT&T common stock will be worth more or less at any
point in the future than the securities you would own if you do not tender these
shares.

RISK FACTORS RELATING TO THE SPIN-OFF

  We may not complete the spin-off as we plan

     On October 25, 2000, AT&T announced that, subject to a number of
conditions, we intend to separate AT&T Wireless Group from AT&T. We expect to
complete the spin-off in the middle of 2001. We cannot, however, assure you that
those conditions, which include receipt of a favorable ruling from the IRS, the

                                       22
<PAGE>   29

satisfaction by AT&T of the conditions in a credit agreement it expects to enter
into prior to completion of the spin-off and the receipt of other approvals,
will all be satisfied or that circumstances will not exist or that events will
not occur that will make it inadvisable to complete the spin-off. Accordingly,
we cannot assure you that the spin-off will occur or that if it does occur, that
it will occur on the terms and in the manner described or in the time frame
contemplated. The failure to accomplish the spin-off could materially adversely
affect the trading prices of AT&T common stock and AT&T Wireless Group tracking
stock.

     In addition, in connection with DoCoMo's strategic investment in AT&T
Wireless Group, AT&T has agreed, if DoCoMo so elects, to repurchase DoCoMo's
interest in AT&T Wireless Group for an aggregate purchase price of $9.8 billion
plus a predetermined rate if AT&T does not complete the spin-off, substantially
in the manner described, of AT&T Wireless Group, by January 1, 2002, or March
15, 2002 if AT&T is trying to obtain a tax ruling, or if AT&T Wireless Group
fails to commence service using an agreed technology in at least 13 of the top
50 domestic markets by June 30, 2004. For more information, please see "Recent
Developments--DoCoMo Strategic Investment" on page 40.

     Although AT&T has no current plans to do so, prior to completion of the
spin-off, AT&T may seek to sell additional equity in AT&T Wireless Group. If any
sale did occur, it would reduce the percentage of the equity interest in AT&T
Wireless Group available for distribution to holders of AT&T common stock in any
spin-off.

  AT&T Wireless Group has substantial capital needs that are key to its business
  strategy, and these capital needs may not be met if the spin-off does not
  occur and AT&T Wireless Group remains a part of AT&T

     As discussed in the "Risk Factors -- Risks Relating to the Business of AT&T
Wireless Group" and "Business of AT&T Wireless Group," AT&T Wireless Group has
and will continue to have substantial capital needs in order to fund its
business strategy and remain competitive. As a result of AT&T's desire to reduce
debt levels and maintain its overall credit rating, the ability of each of
AT&T's business units, including AT&T Wireless Group, to incur substantial
indebtedness, including both third party and intercompany indebtedness, is
restricted relative to its competitors. As a result, if the spin-off does not
occur in the time frame contemplated, AT&T Wireless Group is likely to face
significant capital constraints that would make it difficult for the AT&T
Wireless Group to continue to pursue its growth strategy in a capital intensive
and highly competitive industry. In such event, these constraints are likely to
have a material adverse effect on AT&T Wireless Group. For more information on
the risks associated with AT&T Wireless Group's ability to raise financing
following the spin-off, see "--AT&T Wireless Group will need to pursue financing
on a stand-alone basis" below.

  AT&T Wireless Group will need to pursue financing on a stand-alone basis

     Historically, all financing for AT&T Wireless Group was done by AT&T at the
parent level, which means that AT&T was able to use its overall balance sheet to
finance the operations of AT&T Wireless Group. If the spin-off is completed,
AT&T Wireless Services will be an independent entity and be required to raise
financing on a stand-alone basis without reference to AT&T's overall balance
sheet. Although AT&T and AT&T Wireless Group believe that providing AT&T
Wireless Services with the ability to incur indebtedness without regard to
potential adverse consequences to AT&T's overall credit rating will be
beneficial to AT&T Wireless Services, we cannot assure you that following
completion of the spin-off AT&T Wireless Services will be able to secure
adequate debt or equity financing on desirable terms. The cost to AT&T Wireless
Services of stand-alone financing may be materially higher than the cost of
financing that AT&T Wireless Group incurred as part of AT&T.

     At the time of the spin-off, AT&T Wireless Group is expected to be required
to repay all intercompany indebtedness owed to AT&T and to redeem all preferred
equity in AT&T Wireless Group held by AT&T. As of September 30, 2000, the
aggregate amount of this intercompany debt and preferred stock would have been
approximately $4.8 billion. The actual amount to be repaid at the time of the
spin-off may materially exceed this amount. As a result, AT&T Wireless Services
expects to require substantial capital to meet the funding requirements arising
from both the intercompany debt repayment and its ongoing business needs and to
satisfy its business growth strategy. In addition, while the intercompany debt
has been designed to be substantially

                                       23
<PAGE>   30

equivalent to the interest rates and other terms and conditions that AT&T
Wireless Group would be able to obtain from third parties as a non-affiliate of
AT&T, it is unlikely that those rates and structures will be replicated with the
new debt, which will be based on market conditions and the business financial
profile of AT&T Wireless Services at the time the debt is issued. The credit
ratings of AT&T Wireless Services may be different than the historical ratings
of AT&T. Differences in credit ratings affect the interest rate charged on
financings, as well as the amounts of indebtedness, types of financing
structures and debt markets that may be available to AT&T Wireless Services.
Accordingly, we cannot assure that AT&T Wireless Services will be able to raise
the capital it requires on desirable terms.

  AT&T Wireless Group has no recent history of operating other than as part of
  an integrated telecommunications provider and no recent history of operating
  as an independent entity; it may be unable to make the changes necessary to
  operate as an independent entity; it may incur greater costs as an independent
  entity than has historically been the case

     AT&T Wireless Group has historically been part of an integrated
telecommunications provider since its acquisition by AT&T in 1994. We cannot
assure you that its ability to compete in the short-term or long-term will not
be materially adversely effected by its separation from the other
telecommunications businesses of AT&T.

     Prior to the spin-off, the businesses of AT&T Wireless Group were operated
by AT&T as a segment of its broader corporate organization rather than as an
independent company. AT&T assisted AT&T Wireless Group by providing financing,
as well as by providing other corporate functions and services.

     Following the spin-off, AT&T will have no obligation to provide financial,
operational or organizational assistance to AT&T Wireless Group other than the
services which will be provided by AT&T which are described in "Relationship
Between AT&T Wireless Group and AT&T following the Spin-Off." Because the
businesses of AT&T Wireless Group have not been operated as an independent
entity, we cannot assure you that AT&T Wireless Group will be able to implement
successfully the changes necessary to operate independently or that AT&T
Wireless Group will not incur additional costs operating independently that
would cause its cash flow and results of operations to decline materially. In
addition, AT&T Wireless Services may be able to participate in some of AT&T's
supplier arrangements where those arrangements permit this or the vendors agree
to this and AT&T Wireless Services may also enter into its own supplier
arrangements. We cannot assure you that its supplier arrangements will be as
favorable as has historically been the case.

  The historical financial information of AT&T Wireless Group may not be
  representative of its results as an independent entity and, therefore, may not
  be reliable as an indicator of its historical or future results

     The historical financial information we have included and incorporated in
this document may not reflect what the results of operations, financial position
and cash flows of AT&T Wireless Group would have been had it been an independent
entity during the periods presented or what its results of operations, financial
position and cash flows will be in the future. This is because:

     - the combined financial statements reflect allocations for services
       provided to AT&T Wireless Group by AT&T, which allocations may not
       reflect the costs AT&T Wireless Group will incur for similar or
       incremental services as an independent entity; and

     - the pro forma financial information does not reflect changes that we
       expect AT&T Wireless Group to incur in the future as a result of the
       separation of AT&T Wireless Group from AT&T, except for the repayment of
       all intercompany indebtedness and redemption of all preferred equity in
       AT&T Wireless Group held by AT&T Common Stock Group.

                                       24
<PAGE>   31

     Completion of the spin-off will include transactions with a variety of
effects on AT&T Wireless Group

     In connection with the spin-off, it is expected that AT&T Wireless Group
and AT&T will engage in a series of transactions that include the following:

     - Prior to the spin-off, AT&T Wireless Services will repay all intercompany
       indebtedness owed to AT&T and will redeem all preferred equity in AT&T
       Wireless Group held by AT&T Common Stock Group. As of September 30, 2000,
       these amounts were approximately $1.8 billion and $3.0 billion,
       respectively, or an aggregate of approximately $4.8 billion. The actual
       amount expected to be repaid at the time of the spin-off may materially
       exceed this amount.

     - The employee benefit agreement to be entered into in connection with the
       spin-off provides that a portion of existing AT&T employee stock-based
       obligations will be converted into options to acquire shares of AT&T
       Wireless Services common stock and that AT&T Wireless Services will
       assume other specified obligations. The separation and distribution
       agreement to be entered into in connection with the spin-off provides
       that in exchange for AT&T Wireless Group's undertaking its obligations
       under the employee benefit agreement, the AT&T Common Stock Group will
       reduce its retained inter-group interest in AT&T Wireless Group by
       12,577,610 nominal shares of AT&T Wireless Group tracking stock. As of
                   ,      , based on the closing price of the AT&T Wireless
       Group tracking stock, the value of such reduction is approximately $
       million.

     - As a result of the spin-off, AT&T Wireless Services will cease to be a
       member of the consolidated federal income tax return group of which AT&T
       is the common parent. Consequently, taxable income and losses (as well as
       other tax attributes) of AT&T Wireless Group in post spin-off taxable
       periods could generally no longer offset taxable income or losses (as
       well as other tax attributes) of the AT&T consolidated tax return group.
       For two taxable years after the spin-off, under federal income tax rules,
       AT&T Wireless Group would generally be able to carry back any such tax
       losses (subject to certain limitations) against taxable income, if any,
       of members of AT&T Wireless Group for pre spin-off periods. Under the tax
       sharing agreement between AT&T and AT&T Wireless Group, as amended,
       however, AT&T Wireless Group generally is only permitted to carry back
       net operating losses (and not other tax attributes) from post spin-off
       taxable periods to pre spin-off taxable periods if such losses are
       significant and with the consent of AT&T, which consent AT&T has agreed
       not to withhold unreasonably. To the extent AT&T Wireless Group, is
       expected to have tax losses in post spin-off taxable periods, it would
       generally no longer be entitled to receive current tax sharing payments
       with respect to such losses. Instead, except where such losses can be
       carried back, it would benefit from such losses only if and when AT&T
       Wireless Group generated sufficient taxable income in future years to
       utilize such tax losses on a stand-alone basis.

     - Under the separation and distribution agreement, subject to certain
       limited exceptions, AT&T Wireless Services will be responsible for any
       tax liability and any related liability that results from the spin-off
       failing to qualify as a tax-free transaction. Furthermore, the separation
       and distribution agreement prohibits AT&T Wireless Services for a period
       of 30 months following the spin-off, from entering into certain
       transactions that could render the spin-off taxable. This may discourage,
       delay or prevent a merger, change of control, or other strategic
       transaction involving the issuance of equity by AT&T Wireless Services.

     - Other agreements to be entered into in connection with the spin-off,
       including a separation and distribution agreement and agreements covering
       the use of the AT&T brand and related marks, other intellectual property
       and commercial and service arrangements, mean that the business of AT&T
       Wireless Group will be conducted differently, and that its relationship
       with AT&T will be different, from that which has historically been the
       case. We cannot assure you that these differences will not have a
       material adverse effect on the results of operations or financial
       condition of AT&T or AT&T Wireless Group.

                                       25

  Because there has not been any public market for AT&T Wireless Services common
  stock and because of the business in which AT&T Wireless Group is engaged, the
  market price and trading volume of AT&T Wireless Services common stock may be
  volatile

     Prior to the spin-off, there will be no trading market for shares of AT&T
Wireless Services common stock which holders of AT&T common stock and AT&T
Wireless Group tracking stock will receive in the spin-off. Accordingly, we
cannot predict the extent to which investors' interest will lead to a liquid
trading market or whether the market price of AT&T Wireless Services common
stock will be volatile. In addition, after the spin-off, the percentage of AT&T
Wireless Services represented by publicly held shares will increase materially.
This increase may result in short- or long-term negative pressure on the trading
price of shares of AT&T Wireless Services common stock. The market price of AT&T
Wireless Services common stock could fluctuate significantly for many reasons,
including in response to the risk factors listed in this document or for
specific reasons unrelated to the performance of AT&T Wireless Services. AT&T
Wireless Services common stock may be considered a technology stock by
investors. Technology stocks have typically experienced extreme price and volume
fluctuations. Therefore, the market price and trading volume of AT&T Wireless
Services common stock also may be extremely volatile.

  Anti-takeover provisions of the AT&T Wireless Services' charter and by-laws,
  AT&T Wireless Services' rights agreement, provisions of Delaware law and
  provisions of the agreements to be entered into in connection with the
  spin-off, as well as our agreements with DoCoMo, could delay or prevent a
  change of control that you may favor

     Provisions of AT&T Wireless Services' charter and by-laws, its rights
agreement and provisions of applicable Delaware law, which will be in effect
after the spin-off, may discourage, delay or prevent a merger or other change of
control that shareowners may consider favorable or may impede the ability of the
holders of AT&T Wireless Services common stock to change AT&T Wireless Services'
management. The provisions of AT&T Wireless Services' charter and By-Laws, among
other things, will:

     - divide AT&T Wireless Services' board of directors into three classes,
       with members of each class to be elected in staggered three-year terms;

     - limit the right of shareholders to remove directors;

     - eliminate the right of shareholders to act by written consent or to call
       special meetings;

     - regulate how shareholders may present proposals or nominate directors for
       election at annual meetings of shareholders; and

     - authorize AT&T Wireless Services' board of directors to issue preferred
       stock in one or more series, without shareholder approval.

     Our agreements with DoCoMo may have provisions with a similar effect. For
more information, see "Recent Developments -- DoCoMo Strategic Investments."

     In addition, some of the agreements that AT&T and AT&T Wireless Services
expect to enter into in connection with the spin-off, including the brand
license agreement, network services agreement and other commercial agreements,
are expected to contain provisions which give one party rights in the event of a
change of control of the other party and accordingly may serve to deter certain
changes of control. In the event of certain changes of control, the exercise of
these rights could have a material adverse effect on AT&T Wireless Services or
AT&T.

     See "Relationship between AT&T and AT&T Wireless Group following the
Spin-Off" and "Description of AT&T Wireless Services Capital Stock following the
Spin-Off" for a more detailed description of these agreements and provisions.
Also, although we have not yet made any determination, it is possible that the
charter, by-laws and other constituent documents of the other companies created
by AT&T's restructuring plan will also contain provisions that could delay or
prevent a change of control of those companies that you may favor.

RISK FACTORS RELATING TO THIS EXCHANGE OFFER

  You will be affected by this exchange offer whether or not you tender your
  shares of AT&T common stock

     Your investment in AT&T will be subject to different risks as a result of
this exchange offer. As a holder of shares of AT&T common stock, you will be
affected by this exchange offer regardless of whether you tender all, some or
none of your shares of AT&T common stock in this exchange offer:

     - If you exchange all of your shares of AT&T common stock for shares of
       AT&T Wireless Group tracking stock in this exchange offer, you will have
       an increased interest in the financial performance of AT&T Wireless
       Group. However, you will no longer participate in any change in the value
       of AT&T common stock because you will no longer own any shares of AT&T
       common stock.

     - If you exchange some, but not all, of your shares of AT&T common stock in
       this exchange offer, you will generally have an increased interest in the
       financial performance of AT&T Wireless Group, and a diminished interest
       in the financial performance of AT&T's businesses other than AT&T
       Wireless Group, assuming that you exchange a greater percentage of your
       shares of AT&T common stock than the percentage of all outstanding shares
       of AT&T common stock that are exchanged in this exchange offer.

     - If you do not exchange any of your shares of AT&T common stock in this
       exchange offer, you will continue to participate in any change in the
       value of AT&T common stock. However, because of the shares of AT&T
       Wireless Group tracking stock issued in this exchange offer, you will
       have a diminished interest in the financial performance of AT&T Wireless
       Group.

  You may not receive any premium on the issuance of AT&T Wireless Group
  tracking stock in exchange for AT&T common stock

     We cannot predict whether or to what extent there will be a premium at the
end of this exchange offer. As a result, if you tender your shares of AT&T
common stock in this exchange offer, you may not receive any premium. Any
premium that you would receive through your participation in this exchange offer
will depend upon a variety of factors including the market prices of shares of
AT&T common stock and AT&T Wireless Group tracking stock at the time of the
closing of this exchange offer, which we cannot predict. Even if you receive a
premium in this exchange offer, it is possible that over time, the market value
of the number of shares of AT&T common stock tendered and accepted in this
exchange offer will exceed the market value of the AT&T Wireless Group tracking
stock received in this exchange offer.

  The issuance of AT&T Wireless Group tracking stock in this exchange offer may
  adversely affect the market price of AT&T Wireless Group tracking stock and/or
  AT&T common stock

     This exchange offer could increase substantially the number of publicly
held shares of AT&T Wireless Group tracking stock and the number of AT&T
Wireless Group tracking shareholders. The shares of AT&T Wireless Group tracking
stock to be issued to the shareholders in this exchange offer will generally be
eligible for immediate resale in the open market. If a significant number of
shareholders that receive shares of AT&T Wireless Group tracking stock in this
exchange offer attempt to sell those shares on the open market after this
exchange offer, the market price of AT&T Wireless Group tracking stock could be
adversely affected. In addition, this exchange offer may adversely affect the
market price of AT&T common stock, including by reducing the value of AT&T
Common Stock Group's retained interest in AT&T Wireless Group.

RISK FACTORS RELATING TO THE BUSINESS OF AT&T WIRELESS GROUP

  AT&T Wireless Group may substantially increase its debt level in the future,
  which could subject it to various restrictions and higher interest costs, and
  decrease its profitability

     AT&T Wireless Group may substantially increase its debt in the future. AT&T
Wireless Group currently anticipates requiring substantial additional financing
for the foreseeable future to fund capital expenditures, license purchases and
costs and expenses in connection with funding its operations, domestic and
international investments and its growth strategy and in order to repay
indebtedness and preferred stock owed to or held by AT&T and affiliated entities
at the time of the spin-off. As of September 30, 2000, the aggregate amount of
                                       27
<PAGE>   34

this intercompany debt and preferred stock was approximately $4.8 billion. The
actual amount to be repaid at the time of the spin-off may materially exceed
this amount. AT&T and AT&T Wireless Group are exploring and evaluating the
relative advantages and disadvantages of various funding mechanisms for AT&T
Wireless Services. The alternatives being considered include long-term debt
offerings, bank credit lines, commercial paper, and other forms of public and
private debt facilities. The decision on debt composition is dependent on, among
other things, the business and financial plans of AT&T Wireless Group and the
market conditions at the time of financing. The agreements governing this
indebtedness may contain financial and other covenants that could impair the
flexibility of AT&T Wireless Group and restrict its ability to pursue growth
opportunities. We cannot assure you that AT&T Wireless Group will be able to
secure adequate debt or equity financing on desirable terms.

  AT&T Wireless Group has significant network build out that needs to be
  completed

     AT&T Wireless Group needs to complete significant remaining build out
activities, including completion of build out activities in some of its existing
wireless markets. As AT&T Wireless Group continues to build out its network, it
must, among other things, continue to:

     - lease, acquire or otherwise obtain rights to a large number of cell and
       switch sites,

     - obtain zoning variances or other local governmental or third-party
       approvals or permits for network construction,

     - complete the radio frequency design, including cell site design,
       frequency planning and network optimization, for each of its remaining
       markets,

     - complete the fixed network implementation, which includes designing and
       installing network switching systems, radio systems, interconnecting
       facilities and systems, and operating support systems, and

     - expand and maintain customer care, network management, billing and other
       financial and management systems.

In addition, in the next several years, AT&T Wireless Group will start to
implement upgrades to its network to access the next generation of digital
technology. AT&T Wireless Group recently announced a third generation technology
strategy that includes the deployment of a GSM network and other technologies
beginning in 2001, earlier than its previous third generation technology plan.

     We cannot assure you that these events will occur in the time frame AT&T
Wireless Group assumes or that the Federal Communications Commission requires,
or at the cost AT&T Wireless Group assumes, or at all. Additionally, problems in
vendor equipment availability, technical resources or system performance could
delay the launch of new or expanded operations in new or existing markets or
result in increased costs in all markets. Failure or delay to complete the build
out of the network and launch operations, or increased costs of this build out
and launch of operations, could have a material adverse effect on the operations
and financial condition of AT&T Wireless Group. AT&T Wireless Group intends to
rely on the services of various companies that are experienced in design and
build out of wireless networks in order to accomplish its build out schedule. We
cannot assure you, however, that AT&T Wireless Group will be able to obtain
satisfactory contractors on economically attractive terms or that the
contractors obtained will perform as expected.

  AT&T Wireless Group has substantial capital requirements and needs for
  substantial capital expenditures

     The operation, expansion and upgrade of AT&T Wireless Group's network and
the marketing and distribution of its products and services will continue to
require substantial capital. AT&T Wireless Group has also entered into various
purchase commitments for network equipment, as well as handsets. Additionally,
AT&T Wireless Group anticipates that it will enter into additional material
purchase commitments associated with the development of its third generation
strategy. AT&T Wireless Group also has entered into agreements for investments
and ventures which have required or will require substantial capital. These
agreements also may contain provisions potentially requiring substantial
additional capital in future circumstances, such as allowing the other investors
to require AT&T Wireless Group to purchase assets or investments. The terms

                                       28
<PAGE>   35

and costs of these purchases are based on a variety of factors and are not in
all cases currently calculable but nevertheless may be significant when the
requirement is to be fulfilled.

     AT&T Wireless Group currently estimates that its capital expenditures for
build out of its networks, including expenditures related to its fixed wireless
operations during 2000 will total approximately $4.3 billion. Although
third-generation technology deployment plans involve an integrated network and
in which one cannot definitively allocate capital expenditures between voice and
data components, AT&T Wireless Group has estimated that the capital expenditures
for the high speed data component of its third-generation plans over the next
four years will be approximately $10 per covered POP. These capital expenditures
are in addition to those anticipated to be incurred in connection with AT&T
Wireless Group's voice network, fixed wireless network and other capital
expenditure requirements. As a result, AT&T Wireless Group expects capital
expenditures for the year 2001 to materially exceed those of 2000. AT&T Wireless
Group also expects to incur substantial capital expenditures in future years.
The actual amount of the funds required to finance AT&T Wireless Group's network
build out and other capital expenditures may vary materially from management's
estimate. AT&T Wireless Group could also require additional funds in the event
of departures from its current business plan, unforeseen delays, cost overruns,
unanticipated expenses, regulatory changes, engineering design changes, and
technological and other risks.

     AT&T Wireless Group also may require substantial additional capital for,
among other uses, acquisitions of providers of wireless services, spectrum
license or system acquisitions, system development and network capacity
expansion. AT&T Wireless Group is participating in FCC auctions that began in
December 2000, and is making binding bids on its own behalf, and has made
commitments to provide funding to a third party for successful bids of other
parties. Although there can be no assurance that AT&T Wireless Group or such
third party will be successful, successful bids may, directly or indirectly,
create an additional demand for capital.

     As a result of AT&T Wireless Group's various present or future capital
plans or requirements, AT&T Wireless Group will incur significant indebtedness.
In addition, we may not be able to arrange additional financing to fund AT&T
Wireless Group's capital requirements on terms acceptable to us or AT&T Wireless
Group. Failure to obtain any such financing could result in the delay, change or
abandonment of AT&T Wireless Group's development or expansion plans or the
failure to meet regulatory build-out requirements which would materially
adversely affect AT&T Wireless Group.

 AT&T Wireless Group's business and operations would be adversely affected if it
 fails to acquire adequate radio spectrum in FCC auctions or through other
 transactions

     AT&T Wireless Group anticipates that it will need additional spectrum
capacity in new and existing markets in order to meet the expanded demands for
its existing services as well as to develop future services. AT&T Wireless Group
intends to continue to acquire more spectrum through a combination of
alternatives: participation in spectrum auctions, purchase of spectrum licenses
from companies who own them or purchase of such companies outright. Failure to
obtain the necessary spectrum may have a material adverse impact on the quality
of AT&T Wireless Group services or its ability to roll out third generation
services.

     One method of acquiring spectrum is through FCC auctions. Auction
participants must qualify with the FCC to be allowed to participate. Spectrum
licenses are auctioned in connection with particular geographic markets, and the
availability of spectrum to particular bidders may be limited by regulation.
Bids submitted during the auction process are binding upon the bidder when made,
subject to certain limited exceptions; however, being the high bidder during any
particular round of the auction offers no assurance of being the winner at the
conclusion of the auction. AT&T Wireless Group participates in FCC spectrum
auctions when commercially and strategically reasonable to do so, such as the C
and F block auctions that began in December 2000. The FCC determines what
spectrum will be made available for auction, but there can be no assurances that
the FCC will allocate spectrum sufficient to meet the demands of all those
wishing to obtain licenses. We cannot assure you that AT&T Wireless Group will
be successful in the current or future auctions in obtaining in these auctions
the spectrum that it believes is necessary to implement its business and
technology strategies.

                                       29
<PAGE>   36

     AT&T Wireless Group may also seek to acquire radio spectrum through
purchases and swaps with other wireless communications providers or otherwise,
including by purchases of other providers outright. We cannot assure you,
however, that AT&T Wireless Group will be able to acquire sufficient spectrum
through these types of transactions, or that it will be able to complete any of
these transactions on favorable terms.

  The relationship with DoCoMo contains certain features that will affect the
  way in which the business of AT&T Wireless Group is conducted

     In November 2000, AT&T, AT&T Wireless Services and DoCoMo entered into a
binding letter agreement, and entered into definitive documentation on December
20, 2000, more particularly described under "Recent Developments -- DoCoMo
Strategic Investment." The agreements contain requirements and contingencies
that could materially adversely affect the financial condition and technology
strategies of the business.

     The terms of this investment enable DoCoMo to terminate its investment and
require repayment of its $9.8 billion investment, plus interest at a
predetermined rate, if AT&T does not complete the spin-off substantially in the
manner described, of AT&T Wireless Group, by January 1, 2002, or March 15, 2002
if AT&T is trying to obtain a tax ruling, or if AT&T Wireless Group fails to
commence service using an agreed technology in at least 13 of the top 50
domestic markets by June 30, 2004. Although the current plans of AT&T and AT&T
Wireless Group are consistent with these requirements, there can be no assurance
that events may not arise that would cause these contingencies to occur,
permitting DoCoMo to require this repayment and causing the consequent material
adverse effects of terminating its investment and certain technology rights
provided by DoCoMo.

     After the spin-off, AT&T Wireless Services will require DoCoMo's consent
for certain business actions that otherwise would be in the discretion of the
company, regarding the scope of its business and joint ventures of a certain
magnitude with another wireless operator. These limitations could prevent AT&T
Wireless Services from taking advantage of otherwise beneficial business
opportunities or relationships.

  Potential acquisitions may require AT&T Wireless Group to incur substantial
  additional debt and integrate new technologies, operations and services, which
  may be costly and time consuming

     An element of AT&T Wireless Group's strategy is to expand its network,
which AT&T Wireless Group may do through the acquisition of licenses, systems
and wireless providers. These acquisitions may cause AT&T Wireless Group to
incur substantial additional indebtedness to finance the acquisitions or to
assume indebtedness of the entities that are acquired. In addition, AT&T
Wireless Group may encounter difficulties in integrating those acquired
operations into its own operations, including as a result of different
technologies, systems, services or service offerings. These actions could prove
costly or time consuming or divert management's attention from other business
matters.

  Failure to develop future business opportunities may have an adverse effect on
  AT&T Wireless Group's growth potential

     AT&T Wireless Group intends to pursue a number of new growth opportunities,
including wireless data and fixed wireless services. These opportunities involve
new services for which there are no proven markets. In addition, the ability to
deploy and deliver these services relies, in many instances, on new and unproven
technology. We cannot assure you that AT&T Wireless Group's existing technology
will perform as expected or that AT&T Wireless Group will be able to
successfully develop new technology to effectively and economically deliver
these services. In addition, these opportunities require substantial capital
outlays and spectrum availability to deploy on a large scale. We cannot assure
you that this capital or spectrum will be available to support these services.
Furthermore, each of these opportunities entails additional specific risks. For
example, the delivery of fixed wireless services requires AT&T Wireless Group to
provide installation and maintenance services, which the AT&T Wireless Group has
never provided previously. This will require AT&T Wireless Group to hire,
employ, train and equip technicians to provide installation and repair in each
market served, or rely on subcontractors to perform these services. We cannot
assure you that AT&T Wireless Group will be able to hire and train sufficient
numbers of qualified employees or subcontract these services, or do so on
economically attractive terms. The success of wireless data services, on the
other hand, is

                                       30
<PAGE>   37

substantially dependent on the ability of others to develop applications for
wireless devices and to develop and manufacture devices that support wireless
applications. We cannot assure you that these applications or devices will be
developed or developed in sufficient quantities to support the deployment of
wireless data services.

     AT&T Wireless Group cannot guarantee when or that these services will be
widely introduced and fully implemented, that they will be successful when they
are in place, or that customers will purchase the services offered. If these
services are not successful or costs associated with implementation and
completion of the roll out of these services materially exceed those currently
estimated by AT&T Wireless Group, AT&T Wireless Group's financial condition and
prospects could be materially adversely affected.

  AT&T Wireless Group faces substantial competition

     There is substantial competition in the wireless telecommunications
industry. AT&T Wireless Group expects competition to intensify as a result of
the entrance of new competitors and the development of new technologies,
products and services. Other two-way wireless providers, including other
cellular and personal communications services, or PCS, operators and resellers,
serve each of the markets in which AT&T Wireless Group competes. A majority of
markets will have five or more commercial mobile radio service providers, and
all of the top 50 metropolitan markets have at least four, and in some cases as
many as seven or more, facilities-based wireless service providers offering
wireless services on cellular, PCS or specialized mobile radio frequency.
Competition also may increase to the extent that smaller, stand-alone wireless
providers transfer licenses to larger, better capitalized and more experienced
wireless providers.

     AT&T Wireless Group anticipates that market prices for two-way wireless
services generally will decline in the future due to increased competition. We
expect significant competition among wireless providers, including from new
entrants, to continue to drive service and equipment prices lower. AT&T Wireless
Group also expects that there will be increases in advertising and promotional
spending, along with increased demands on access to distribution channels. All
of this may lead to greater choices for customers, possible consumer confusion
and increasing movement of customers between competitors, which we refer to as
"churn". AT&T Wireless Group's ability to compete successfully also will depend
on marketing and on its ability to anticipate and respond to various competitive
factors affecting the industry, including new services, changes in consumer
preferences, demographic trends, economic conditions and discount pricing
strategies by competitors.

     The wireless communications industry has been experiencing significant
consolidation and AT&T Wireless Group expects that this consolidation will
continue. The previously announced mergers or joint ventures of Bell Atlantic
Corporation/GTE Corporation/Vodafone/AirTouch plc, now called Verizon,
SBC/Bell-South, now called Cingular, have created large, well-capitalized
competitors with substantial financial, technical, marketing and other resources
to respond to AT&T Wireless Group's offerings. In addition, in July 2000,
VoiceStream Communications and Deutsche Telecom publicly announced a planned
merger. These mergers or ventures have caused AT&T Wireless Group's ranking to
decline to third in U.S. revenue and U.S. subscriber share. In terms of U.S.
population covered by licenses, or POPs, AT&T Wireless Group, including
partnerships and affiliates, ranks third. As a result, these competitors may be
able to offer nationwide services and plans more quickly and more economically
than AT&T Wireless Group and to obtain roaming rates that are more favorable
than those obtained by AT&T Wireless Group, and may be better able to respond to
offers of AT&T Wireless Group.

  AT&T Wireless Group expects to experience significant change in the wireless
  industry

     The wireless communications industry is experiencing significant
technological change. This includes the increasing pace of digital upgrades in
existing analog wireless systems, evolving industry standards, ongoing
improvements in the capacity and quality of digital technology, shorter
development cycles for new products, and enhancements and changes in end-user
needs and preferences. There is also uncertainty as to the pace and extent that
customer demand will continue to increase, as well as the extent to which
airtime and monthly recurring charges may continue to decline. As a result, the
future prospects of the industry and AT&T

                                       31
<PAGE>   38

Wireless Group and the success of its competitive services remain uncertain.
Also, alternative technologies may develop for the provision of services to
customers that may provide wireless communications service or alternative
service superior to that available from AT&T Wireless Group. Thus, AT&T Wireless
Group cannot give assurance that technological developments will not materially
adversely affect it.

  Termination or impairment of AT&T Wireless Group's relationship with a small
  number of key suppliers could adversely affect AT&T Wireless Group's revenues
  and results of operations

     AT&T Wireless Group has developed relationships with a small number of key
vendors, including Nokia Mobile Phones, Inc., Telefonaktiebolaget LM Ericsson,
Mitsubishi Corporation and Motorola, Inc. for its supply of wireless handsets,
Lucent Technologies, Inc., Nortel Networks, Inc., Ericsson and Nokia Networks,
Inc. for its supply of telecommunications infrastructure equipment and Convergys
Information Management Group for its billing services. AT&T Wireless Group does
not have operational or financial control over its key suppliers, and has
limited influence with respect to the manner in which these key suppliers
conduct their businesses. If these key suppliers were unable to honor their
obligations to AT&T Wireless Group, it could disrupt the business of AT&T
Wireless Group and adversely impact its revenues and results of operations.

  There is no guarantee that AT&T Wireless Group's technology will be
  competitive with other technologies or compatible with next generation
  technology

     There are three existing digital technologies, none of which is compatible
with the others. AT&T Wireless Group selected Time Division Multiple Access, or
TDMA, technology for its second generation network because it believes that this
technology offers several advantages over other second generation technologies.
However, a number of other wireless service providers chose code division
multiple access, or CDMA, or GSM, as their digital wireless technology. For the
next generation technology, AT&T Wireless Group has chosen a GSM platform to
deploy GPRS (general packet radio service)/EDGE (enhanced data for global
evolution) and ultimately UMTS (universal mobile telecommunications systems)
services. There is no guarantee that this technology will provide the advantages
AT&T Wireless Group expects. Other wireless providers have chosen CDMA 2000, a
competing wideband technology, as their third generation technology. If UMTS
does not gain widespread acceptance, it would materially adversely affect the
business, financial condition and prospects of AT&T Wireless Group. As AT&T
Wireless Group develops its 3G GSM-based networks, it will continue to incur
substantial costs associated with maintaining its TDMA networks. Also, these
networks are not compatible, and customers with phones that operate on one
network will not initially be able to use those phones on the other network.
There are certain risks inherent in the development of new third generation
equipment and we cannot assure you that we will not face unforeseen costs,
delays or problems that may have a material adverse affect.

  AT&T Wireless Group relies on favorable roaming arrangements, which it may be
  unable to continue to obtain

     AT&T Wireless Group's customers automatically can access another provider's
analog cellular or digital system or PCS system only if the other provider
allows AT&T Wireless Group's customers to roam on its network. AT&T Wireless
Group relies on agreements to provide roaming capability to its customers in
many areas of the United States that AT&T Wireless Group's network does not
serve. Some competitors, because of their call volumes or their affiliations
with, or ownership of, wireless providers, however, may be able to obtain
roaming rates that are lower than those rates obtained by AT&T Wireless Group.

     We cannot assure you that AT&T Wireless Group will continue to be able to
obtain or maintain roaming agreements with other providers on terms that are
acceptable to it. In addition, the quality of service that a wireless provider
delivers during a roaming call may be inferior to the quality of service AT&T
Wireless Group or an affiliated company provides, the price of a roaming call
may not be competitive with prices of other wireless providers for such call,
and AT&T Wireless Group's customer may not be able to use any of the advanced
features, e.g., voicemail notification, that the customer enjoys when making
calls within AT&T Wireless Group's network. Finally, we cannot assure you that
AT&T Wireless Group will obtain favorable roaming agreements for its GSM-based
or 3G products and services.

                                       32

  AT&T Wireless Group depends on fourth quarter results

     The wireless industry, including AT&T Wireless Group, has experienced a
trend of generating a significantly higher number of customer additions and
handset sales in the fourth quarter of each year as compared to the other three
fiscal quarters. A number of factors contribute to this trend, including the
increasing use of retail distribution, which is dependent upon the year-end
holiday shopping season, the timing of new product and service announcements and
introductions, competitive pricing pressures, and aggressive marketing and
promotions. We cannot assure you that strong fourth quarter results for customer
additions and handset sales will continue for the wireless industry or AT&T
Wireless Group. In the future, the number of customer additions and handset
sales for AT&T Wireless Group in the fourth quarter could decline for a variety
of reasons, including AT&T Wireless Group's inability to match or beat pricing
plans offered by competitors, failure to adequately promote AT&T Wireless
Group's products, services and pricing plans, or failure to have an adequate
supply or selection of handsets. If in any year fourth quarter results fail to
significantly improve upon customer additions and handset sales from the year's
previous quarters, this could adversely impact AT&T Wireless Group's results for
the following year.

  Media reports have suggested radio frequency emissions may be linked to
  various health concerns and interfere with various medical devices

     Media and other reports have linked radio frequency emissions from wireless
handsets to various health concerns, including cancer, and to interference with
various electronic medical devices, including hearing aids and pacemakers.
Although the expert reviews published to date have concluded that the evidence
does not support a finding of adverse health effects, concerns over radio
frequency emissions may discourage the use of wireless handsets or expose AT&T
Wireless Group to potential litigation, which could have a material adverse
effect on AT&T Wireless Group's results of operations. Additionally, research
and studies are ongoing, and we cannot assure you that further research and
studies will not demonstrate a link between radio frequency emissions and health
concerns.

  The operations of AT&T Wireless Group are subject to various government
  regulations

     The licensing, construction, operation, sale, resale and interconnection
arrangements of wireless communications systems are regulated to varying degrees
by the FCC, and, depending on the jurisdiction, state and local regulatory
agencies. These regulations may include, among other things, required service
features and capabilities, such as universal number portability or emergency 911
service. In addition, the FCC, together with the Federal Aviation Administration
regulates tower marking and lighting. Any of these agencies having jurisdiction
over AT&T Wireless Group's business could adopt regulations or take other
actions that could adversely affect the business of AT&T Wireless Group.

     FCC licenses to provide wireless services or PCS are subject to renewal and
revocation. There may be competition for AT&T Wireless Group's licenses upon
their expiration and we cannot assure you that the FCC will renew them. FCC
rules require all wireless and PCS licensees to meet specified build out
requirements. There can be no assurance that AT&T Wireless Group will be able to
meet these requirements in each market. Failure to comply with these
requirements in a given license area could result in revocation or forfeiture of
AT&T Wireless Group's license for that license area or the imposition of fines
on AT&T Wireless Group by the FCC.

  State and local legislative bodies are considering or have enacted legislation
  to restrict or prohibit wireless phone use while driving

     Legislation has been proposed in some state and local legislative bodies to
restrict or prohibit the use of wireless phones while driving motor vehicles.
These laws have been enacted in other countries, and, to date, a small number of
communities in the United States have passed restrictive local ordinances. In
addition, some studies have indicated that some aspects of using wireless phones
while driving may impair drivers' attention in certain circumstances, making
accidents more likely. If laws are passed prohibiting or restricting the use of
wireless phones while driving, it could have the effect of reducing subscriber
usage, which could cause a material adverse effect on AT&T Wireless Group's
results of operations. Additionally, concerns over the use

                                       33
<PAGE>   40

of wireless phones while driving could lead to potential litigation relating to
accidents, deaths or serious bodily injuries, which also could have material
adverse effects on AT&T Wireless Group's results of operations.

RISK FACTORS RELATING TO AT&T'S CORPORATE STRUCTURE PRIOR TO THE SPIN-OFF

  Holders of AT&T common stock, AT&T Wireless Group tracking stock and Liberty
  Media Group tracking stock are shareholders of one company and, therefore,
  financial impacts on one group could affect the other groups

     Holders of AT&T common stock, AT&T Wireless Group tracking stock and
Liberty Media Group tracking stock are all common shareholders of AT&T, and are
subject to risks associated with an investment in a single company and all of
AT&T's businesses, assets and liabilities. Financial effects arising from one
group that affect AT&T's consolidated results of operations or financial
condition could, if significant, affect the combined results of operations or
financial position of the other groups or the market price of the class of
common shares relating to the other groups. In addition, if AT&T or any of its
subsidiaries were to incur significant indebtedness on behalf of a group,
including indebtedness incurred or assumed in connection with an acquisition or
investment, it could affect the credit rating of AT&T and its subsidiaries.
This, in turn, could increase the borrowing costs of the other groups and AT&T
as a whole. Net losses of any group and dividends or distributions on shares of
any class of common or preferred stock will reduce the funds of AT&T legally
available for payment of future dividends on each of AT&T common stock, AT&T
Wireless Group tracking stock and Liberty Media Group tracking stock. For these
reasons, you should read AT&T's consolidated financial information together with
the financial information of AT&T Common Stock Group, AT&T Wireless Group and
Liberty Media Group.

  We cannot give you assurance as to the market impact of some of the terms of
  AT&T Wireless Group tracking stock

     AT&T cannot predict the market impact of some of the terms of AT&T Wireless
Group tracking stock, such as:

     - the discretion of our board of directors to make determinations affecting
       AT&T Wireless Group tracking stock,

     - redemption and conversion rights in the event AT&T disposes of
       substantially all the assets attributed to AT&T Wireless Group,

     - the ability of AT&T to convert shares of AT&T Wireless Group tracking
       stock into shares of AT&T common stock, or

     - the voting rights of AT&T Wireless Group tracking stock and AT&T common
       stock.

  Holders of AT&T Wireless Group tracking stock will have limited separate
  shareholder rights, and will have no additional rights with respect to their
  group, including direct voting rights

     Holders of AT&T Wireless Group tracking stock do not have any direct voting
rights in AT&T Wireless Group, except to the extent required under AT&T's
charter or New York law. Separate meetings for holders of AT&T Wireless Group
tracking stock are not held. When a vote is taken on any matter as to which all
of our common shares are voting together as one class, any class or series of
our common shares that is entitled to more than the number of votes required to
approve the matter being voted upon is in a position to control the outcome of
the vote on that matter. Currently, each share of AT&T common stock has one
vote, each share of Class B Liberty Media Group tracking stock has 0.375 of a
vote, each share of Class A Liberty Media Group tracking stock has 0.0375 of a
vote and each share of AT&T Wireless Group tracking stock has 0.5 of a vote. The
voting power of each class is subject to adjustment for stock splits, stock
dividends and combinations, including any distribution of AT&T Wireless Group
tracking stock to holders of AT&T common stock.

  Holders of AT&T Wireless Group tracking stock may have potentially diverging
  interests from holders of other classes of AT&T capital stock

     General

     The existence of separate classes of our common stock could give rise to
occasions when the interests of the holders of AT&T common stock, AT&T Wireless
Group tracking stock and/or Liberty Media Group tracking stock diverge, conflict
or appear to diverge or conflict. Examples include determinations by our board
of directors to:

     - pay or omit the payment of dividends on AT&T common stock, AT&T Wireless
       Group tracking stock or Liberty Media Group tracking stock, except where
       such dividends are required,

     - redeem shares of AT&T Wireless Group tracking stock for shares of AT&T
       common stock or stock of qualifying subsidiaries of AT&T,

     - approve dispositions of assets attributed to any group,

     - if and to the extent there is an inter-group interest, allocate the
       proceeds of issuances of AT&T Wireless Group tracking stock either to
       AT&T Common Stock Group with a corresponding reduction in the inter-group
       interest or to the equity of AT&T Wireless Group,

     - formulate public policy positions for AT&T,

     - establish material commercial relationships between groups, and

     - make operational and financial decisions with respect to one group that
       could be considered to be detrimental to another group.

     In addition, decisions regarding distribution and other commercial
arrangements between the groups may affect costs, service alternatives and
marketing approaches for each group. When making decisions with regard to
matters that create potential diverging interests, AT&T's board of directors
will act in accordance with:

     - the terms of AT&T's charter, the AT&T Wireless Group policy statement,
       the Liberty Media Group policy statement and the inter-group agreement
       between AT&T and Liberty Media Group, which governs the relationship
       between AT&T Common Stock Group and Liberty Media Group, to the extent
       applicable, and

     - its fiduciary duties, which require our board of directors to consider
       the impact of these decisions on all shareholders of AT&T.

Our board of directors also could, from time to time, refer to the Liberty Media
Group capital stock committee and AT&T Wireless Group capital stock committee
matters involving any conflict, and have those committees report to our board of
directors on those matters or decide those matters to the extent permitted by
AT&T's by-laws and applicable law.

     Operational and financial decisions

     Our board of directors could, in its sole discretion, from time to time,
but subject to:

     - its fiduciary duties,

     - the AT&T Wireless Group policy statement,

     - the Liberty Media Group policy statement, and

     - the terms of the inter-group agreement between AT&T and Liberty Media
       Group

make operational and financial decisions or implement policies that affect
disproportionately the businesses of a group. These decisions could include:

     - allocation of financing opportunities in the public markets,

     - allocation of business opportunities, resources and personnel, and

     - transfers of services, including sales agency, resale and other
       arrangements, funds or assets between groups and other inter-group
       transactions

that, in each case, may be suitable for one or more groups. Any such decision
may benefit one group more than the other groups. For example, the decision to
obtain funds for one group may adversely affect the ability
                                       35
<PAGE>   42

of the other groups to obtain funds sufficient to implement their respective
growth strategies or may increase the cost of those funds.

     In addition, AT&T Wireless Group is subject to AT&T's existing agreements
or arrangements with third parties. These agreements or arrangements currently
may benefit AT&T Wireless Group, as in the case of purchasing arrangements, or
may have the effect of limiting or impairing its business opportunities. For
example, AT&T and British Telecommunications plc have entered into a joint
venture agreement for the provision of global communications services. As part
of that joint venture agreement, among other things, AT&T has agreed to various
restrictions on its businesses and activities, including non-competition
provisions and exclusive purchasing requirements, all of which will apply to
AT&T Wireless Group.

     Any decisions by our board of directors to renew, extend, modify or
terminate its current agreements or arrangements, or enter into similar
agreements or arrangements in the future, may benefit one group more than the
other group or limit or impair the ability of either group to pursue business
opportunities. Furthermore, overlap between the businesses of the two groups may
increase as a result of regulatory changes, technological advancements or other
factors that will make those operational and financial decisions more difficult.

     All of these decisions will be made by our board of directors in its good
faith business judgment and in accordance with procedures and policies adopted
by our board of directors from time to time, including the AT&T Wireless Group
policy statement described under "Relationship between AT&T Common Stock Group
and AT&T Wireless Group prior to the Spin-Off -- AT&T Wireless Group Policy
Statement."

     Changes in the tax law or in the interpretation of current tax law may
     result in redemption of AT&T Wireless Group tracking stock or cessation of
     the issuance of further shares

     From time to time, there have been legislative and administrative proposals
which, if effective, would have resulted in the imposition of corporate level or
shareholder level tax upon the issuance of tracking stock. As of the date
hereof, no such proposals are outstanding.

     If there are adverse tax consequences to the issuance of AT&T Wireless
Group tracking stock, it is possible that we would cease issuing additional
shares of AT&T Wireless Group tracking stock. This could affect the value of
AT&T Wireless Group tracking stock then outstanding.

     Furthermore, we are entitled to convert AT&T Wireless Group tracking stock
into AT&T common stock at a premium of 10% if, based upon the opinion of tax
counsel, there are adverse U.S. federal income tax law developments related to
AT&T Wireless Group tracking stock that occur after the issuance of AT&T
Wireless Group tracking stock.

     Optional redemption of AT&T Wireless Group tracking stock, including as a
     result of an adverse tax law change

     Our board of directors may, at any time after either the occurrence of
tax-related events such as the ones described above, or May 2, 2002, redeem all
outstanding shares of AT&T Wireless Group tracking stock for shares of AT&T
common stock at a rate per share of AT&T Wireless Group tracking stock equal to
110% of the ratio of the average market price per share of AT&T Wireless Group
tracking stock to the average market price per share of AT&T common stock
computed for the 40 consecutive trading days ending on the 15th trading day
prior to the date that the notice of redemption is sent to holders of AT&T
Wireless Group tracking stock. A decision to redeem shares of AT&T Wireless
Group Tracking Stock could be made at a time when either or both of AT&T common
stock and AT&T Wireless Group tracking stock may be considered to be overvalued
or undervalued. In addition, a redemption at any premium would preclude holders
of AT&T Wireless Group tracking stock from retaining their investment in a
security intended to reflect separately the economic performance of AT&T
Wireless Group. It would also give holders of shares of converted AT&T Wireless
Group tracking stock an amount of consideration that may differ from the amount
of consideration a third-party buyer pays or would pay for all or substantially
all of the assets of the AT&T Wireless Group.

     Dispositions of group assets

     Assuming the assets attributed to any group represent less than
substantially all of the properties and assets of AT&T as a whole, our board of
directors could, in its sole discretion and without shareholder

                                       36
<PAGE>   43

approval, approve sales and other dispositions of any amount of the properties
and assets attributed to a group because the New York Business Corporation Law,
or NYBCL, requires shareholder approval only for a sale or other disposition of
all or substantially all of the properties and assets of the entire company.

     In the event of a disposition of all or substantially all of the properties
and assets attributed to AT&T Wireless Group, generally defined as 80% or more
of the fair value of that group, AT&T will be required to:

     - convert each outstanding share of AT&T Wireless Group tracking stock into
       a number of shares of AT&T common stock equal to 110% of the ratio of the
       average market price per share of AT&T Wireless Group tracking stock to
       the average market price per share of AT&T common stock, or

     - distribute cash and/or securities (other than AT&T common stock) or other
       property equal to the fair value of the net proceeds from that
       disposition allocable to AT&T Wireless Group tracking stock, either by
       special dividend or by redemption of all or part of the outstanding
       shares of AT&T Wireless Group tracking stock, or

     - take a combination of the actions described in the preceding bullets
       whereby AT&T would convert some shares of AT&T Wireless Group tracking
       stock into AT&T common stock at a 10% premium and pay a dividend on the
       remaining shares of AT&T Wireless Group tracking stock or redeem all or
       part of the remaining shares of AT&T Wireless Group tracking stock for
       cash and/or property equal to the fair value of a portion of the net
       proceeds of the disposition allocable to AT&T Wireless Group tracking
       stock.

For this purpose, the "average market price per share" of AT&T common stock or
AT&T Wireless Group tracking stock, as the case may be, means the average of the
daily market value per share for such AT&T common stock or AT&T Wireless Group
tracking stock during the 10-trading day period beginning on the 15th trading
day following completion of that transaction.

     Our board of directors is not required to select the option that would
result in the distribution with the highest value to the holders of AT&T
Wireless Group tracking stock. See "-- The fiduciary duties of our board of
directors to more than one class of common stock are not clear under New York
law" for a discussion of our board of directors' fiduciary duties to the holders
of the different classes of our common shares.

     In addition, under New York law, our board of directors could decline to
dispose of assets of a group despite the request of a majority of the holders of
the tracking stock designed to track the assets and businesses of that group.

     Public policy determinations

     Because of the nature of the businesses of AT&T Common Stock Group, AT&T
Wireless Group and the Liberty Media Group, the groups may have diverging
interests as to the position AT&T should take with respect to various regulatory
issues. For example, FCC regulations that may advance the interests of one group
may not advance the interests of the other groups. Under the AT&T Wireless Group
policy statement, we will resolve material matters involving potentially
divergent interests in a manner that our board of directors, or AT&T Wireless
Group capital stock committee, determines to be in the best interests of AT&T
and all of our common shareholders after giving fair consideration to the
potentially divergent interests and all other relevant interests of the holders
of the separate classes of our common shares. Nevertheless, our board of
directors could take positions on any given issue that may benefit one group
more than another.

  The fiduciary duties of our board of directors to more than one class of
  common stock are not clear under New York law

     Although we are not aware of any legal precedent under New York law
involving the fiduciary duties of directors of corporations having two or more
classes of common stock, or separate classes or series of capital stock,
principles of Delaware law established in cases involving differing treatment of
two classes of capital stock or two groups of holders of the same class of
capital stock provide that a board of directors owes an equal duty to all
shareholders regardless of class or series, and does not have separate or
additional duties to either

                                       37
<PAGE>   44

group of shareholders. Under these principles of Delaware law and the related
principle known as the "business judgment rule," absent abuse of discretion, a
good faith business decision made by a disinterested and adequately informed
board of directors, or a committee of the board of directors, with respect to
any matter having disparate impacts upon holders of AT&T common stock, AT&T
Wireless Group tracking stock or Liberty Media Group tracking stock would be a
defense to any challenge to a determination made by or on behalf of the holders
of any class of our common shares. Nevertheless, a New York court hearing a case
involving this type of a challenge may decide to apply principles of New York
law different from the principles of Delaware law discussed above, or may
develop new principles of law, in order to decide such a case.

  Our board of directors has the ability to control inter-group transactions
  between AT&T Common Stock Group and AT&T Wireless Group

     Our board of directors may decide to transfer funds between groups, which
may result in either a corresponding change in the size of AT&T Common Stock
Group's retained inter-group interest in AT&T Wireless Group, the issuance of an
additional preferred security in AT&T Wireless Group or a loan, or repayment of
a loan, from one group to the other group, subject to the terms of the AT&T
Wireless Group policy statement. Transfers of assets from AT&T Common Stock
Group to AT&T Wireless Group that our board of directors designates as an equity
contribution by AT&T Common Stock Group to AT&T Wireless Group will result in an
increase in the inter-group interest of AT&T Common Stock Group in AT&T Wireless
Group.

     Under the AT&T Wireless Group policy statement, AT&T Common Stock Group may
make loans to AT&T Wireless Group at interest rates and on terms and conditions
substantially equivalent to the interest rates and terms and conditions that
AT&T Wireless Group would be able to obtain from third parties, including the
public markets, as a non-affiliate of AT&T without the benefit of any guaranty
by AT&T or any member of AT&T Common Stock Group. The AT&T Wireless Group policy
statement contemplates that these terms will apply regardless of the interest
rates and terms and conditions on which AT&T or members of AT&T Common Stock
Group may have acquired the subject funds. We anticipate that interest rates
payable by AT&T Wireless Group initially will be higher than those payable by
AT&T or the AT&T Common Stock Group.

     Any increase in the retained inter-group interest resulting from an equity
contribution by AT&T Common Stock Group to AT&T Wireless Group, or any decrease
in the retained inter-group interest resulting from a transfer of funds from
AT&T Wireless Group to AT&T Common Stock Group, would be determined by reference
to the then-current market value of AT&T Wireless Group tracking stock. Such an
increase, however, could occur at a time when those shares are considered under-
or over-valued and such a decrease could occur at a time when those shares are
considered under- or over-valued. Under the AT&T Wireless Group policy
statement, there will be no inter-group interest of AT&T Wireless Group in AT&T
Common Stock Group. Transfers from AT&T Wireless Group to AT&T Common Stock
Group will require other types of consideration when there is no inter-group
interest to offset.

  Our board of directors may change the AT&T Wireless Group Policy Statement or
  our By-Laws without shareholder approval

     The AT&T Wireless Group policy statement governs the relationship between
AT&T Common Stock Group and AT&T Wireless Group and to amend AT&T's by-laws to
create a capital stock committee that will oversee the interaction between the
two groups. Our board of directors may modify, suspend or rescind the policies
set forth in the policy statement or make additions or exceptions to them, in
the sole discretion of our board of directors, without approval of our
shareholders, although there is no present intention to do so. Our board of
directors may also adopt additional policies, depending upon the circumstances.
AT&T's by-laws may similarly be modified, suspended or rescinded. Our board of
directors would make any determination to modify, suspend or rescind these
policies or our by-laws, or to make exceptions to them or adopt additional
policies or by-laws, including any decision that would have disparate impacts
upon holders of AT&T common stock and AT&T Wireless Group tracking stock, in a
manner consistent with its fiduciary duties to AT&T and all of our common
shareholders after giving fair consideration to the potentially divergent
interests and all
                                       38
<PAGE>   45

other relevant interests of the holders of the separate classes of our common
shares, including the holders of AT&T common stock, AT&T Wireless Group tracking
stock and Liberty Media Group tracking stock. See "-- The fiduciary duties of
our board of directors to more than one class of common stock are not clear
under New York law" for more information regarding our board of directors'
fiduciary duties to our shareholders and "Relationship between AT&T Common Stock
Group and AT&T Wireless Group prior to the Spin-Off" for a description of the
AT&T Wireless Group policy statement and our by-laws.

  It will be difficult for a third party to acquire AT&T Wireless Group without
AT&T's consent

     If AT&T Wireless Group were an independent entity, any person interested in
acquiring it without negotiation with our management could seek control of the
outstanding stock of that entity by means of a tender offer or proxy contest.
Although AT&T Wireless Group tracking stock is a class of our common shares that
is intended to reflect the separate economic performance of AT&T Wireless Group,
a person interested in acquiring only AT&T Wireless Group without negotiation
with our management still would be required to seek control of the voting power
represented by all of the outstanding capital stock of AT&T entitled to vote on
that acquisition, including the classes of common shares related to the other
groups. As a result, this may discourage potential interested bidders from
seeking to acquire AT&T Wireless Group. See "-- Holders of AT&T Wireless Group
tracking stock will have limited separate shareholder rights and will have no
additional rights with respect to their group, including direct voting rights"
for more information on the rights of holders of tracking stocks.

  Future sales of AT&T Wireless Group tracking stock and AT&T common stock could
  adversely affect their respective market prices and the ability to raise
  capital in the future

     Sales of substantial amounts of AT&T Wireless Group tracking stock and AT&T
common stock in the public market could hurt the market price of AT&T Wireless
Group tracking stock. This could also hurt AT&T's ability to raise capital in
the future. The shares of AT&T Wireless Group tracking stock that we sold to the
public in the initial public offering and the shares AT&T Wireless Group
tracking stock issued in this exchange offer are freely tradable without
restriction under the Securities Act of 1933 by persons other than "affiliates"
of AT&T, as defined under the Securities Act. Any sales of substantial amounts
of AT&T Wireless Group tracking stock or AT&T common stock in the public market,
or the perception that those sales might occur, could materially adversely
affect the market price of AT&T Wireless Group tracking stock.

     The approval of the shareholders of AT&T and AT&T Wireless Group will not
be solicited by AT&T for the issuance of authorized but unissued shares of AT&T
Wireless Group tracking stock, unless this approval is deemed advisable by our
board of directors or is required by applicable law, regulation or stock
exchange listing requirements. The issuance of those shares could dilute the
value of shares of AT&T Wireless Group tracking stock.

  We do not expect to pay dividends on AT&T Wireless Group tracking stock or
AT&T Wireless Services common stock

     Determinations as to the future dividends on AT&T Wireless Group tracking
stock primarily will be based upon the financial condition, results of
operations and business requirements of AT&T Wireless Group and AT&T as a whole.
We currently do not expect to pay any dividends on AT&T Wireless Group tracking
stock for the foreseeable future, nor do we expect AT&T Wireless Services to pay
any dividends on its common stock for the foreseeable future following the
spin-off.

               RECENT DEVELOPMENTS -- DOCOMO STRATEGIC INVESTMENT

     On November 30, 2000, AT&T, AT&T Wireless Services and NTT DoCoMo, Inc., a
Japanese wireless communications company, entered into a binding letter
agreement, which was superseded by definitive documentation in December 2000.
Under these agreements, DoCoMo has agreed to invest approximately $9.8 billion
for a new class of AT&T preferred stock that would be economically equivalent to
406,255,889 shares of AT&T Wireless Group tracking stock and represent an
approximate 16% economic interest in AT&T Wireless Group. As part of this
investment, DoCoMo will also receive five-year warrants to purchase the
equivalent of an additional 41,748,273 shares of AT&T Wireless Group tracking
stock at $35 per share, and DoCoMo and AT&T Wireless Group will form a strategic
alliance to develop the next generation of mobile multimedia services on a
global-standard, high-speed wireless network. AT&T will retain $3,651,615,431 of
the proceeds of DoCoMo's investment and contribute $6,159,464,289 to AT&T
Wireless Group.

     The investment is expected to be completed during the first quarter of
2001. The following summary of the material provisions of the agreements is
qualified in its entirety by reference to the full text of the agreements, and
copies of these documents have been filed as exhibits to the registration
statement of which this document forms a part and are incorporated into this
document by reference.

New Class of AT&T Wireless Group Tracking Stock

     DoCoMo will purchase 812,511.778 shares of a new class of AT&T preferred
stock, par value $1.00, that we call "New Wireless tracking stock." Each share
of New Wireless tracking stock is intended to be the economic and voting
equivalent of 500 shares of AT&T Wireless Group tracking stock, and is
convertible at any time into 500 shares of AT&T Wireless Group tracking stock.
The New Wireless tracking stock also has some additional rights not available to
holders of AT&T Wireless Group tracking stock. The following is a description of
some of the rights and features of the New Wireless tracking stock.

     - Conversion.  DoCoMo can convert all, and not less than all, of its shares
       of New Wireless tracking stock into AT&T Wireless Group tracking stock at
       a ratio of 500 shares of AT&T Wireless Group tracking stock for each
       share of New Wireless tracking stock, subject to anti-dilution
       protection. If the spin-off occurs, then immediately before the
       completion of the spin-off, each share of New Wireless tracking stock
       automatically will be converted into 500 shares of AT&T Wireless Group
       tracking stock, subject to anti-dilution protection, and thereafter be
       exchanged on the same terms as all other shares of AT&T Wireless Group
       tracking stock in the spin-off.

     - Liquidation Preference.  The New Wireless tracking stock carries an
       aggregate liquidation preference of $3.65 billion in the event of an
       involuntary liquidation or dissolution of AT&T, and holders of New
       Wireless tracking stock are entitled to participate in this preference in
       proportion to the number of shares they hold. The holders of shares of
       New Wireless tracking stock will also be entitled to participate, on an
       as-converted basis, in any additional liquidation payments made to
       holders of AT&T Wireless Group tracking stock, less any amounts received
       out of the $3.65 billion liquidation preference. The New Wireless
       tracking stock has no preference in the event of a voluntary liquidation
       or dissolution of AT&T, but would automatically convert into shares of
       AT&T Wireless Group tracking stock and participate in any liquidation
       payments made to holders of AT&T Wireless Group tracking stock.

     - Dividends.  Holders of New Wireless tracking stock are entitled to
       participate, on an as-converted basis, in any dividends or distributions
       paid to holders of AT&T Wireless Group tracking stock.

     - Voting Rights.  Holders of New Wireless tracking stock are entitled to
       vote together with holders of AT&T common shares and not as a separate
       class. Each share of New Wireless tracking stock is entitled to the
       number of votes that could be cast by the shares of AT&T Wireless Group
       tracking stock into which the New Wireless tracking stock is convertible.
       Initially, each share of New Wireless tracking stock will be entitled to
       250 votes.

     - Redemption at the Option of AT&T.  There are two instances in which AT&T
       may redeem all, and not less than all, of the shares of New Wireless
       tracking stock and warrants owned by DoCoMo at DoCoMo's original purchase
       price plus a predetermined rate. First, if the proposed spin-off does not
       occur before April 26, 2002 and thereafter AT&T redeems all AT&T Wireless
       Group tracking stock,

                                       40
<PAGE>   47

       AT&T may concurrently redeem the New Wireless tracking stock. In this
       case, if AT&T announces a sale of all or substantially all the assets of
       AT&T Wireless Group within a year of redemption and then completes the
       sale, DoCoMo will be entitled to receive a payment equal to the excess of
       the value from that sale that would have been attributable to the New
       Wireless tracking stock over the redemption price. Second, if specified
       adverse tax events occur prior to the proposed spin-off and thereafter
       all AT&T Wireless Group tracking stock is redeemed, AT&T may concurrently
       redeem the New Wireless tracking stock on the same terms as described
       above. In either case, if AT&T spins off all or substantially all of the
       assets of AT&T Wireless Group within a year of redeeming the New Wireless
       tracking stock, DoCoMo will be entitled to reinvest in the spun off
       entity at the redemption price and otherwise on terms comparable to those
       set forth in the letter agreement.

     - Transfer.  Shares of New Wireless tracking stock are not transferable
       other than by conversion into AT&T Wireless Group tracking stock or
       redemption by AT&T.

Warrants

     DoCoMo will acquire 83,496.546 warrants, each of which initially represents
the right to purchase one share of New Wireless tracking stock at an exercise
price of $17,500 per share, subject to customary anti-dilution adjustments.
These warrants may be exercised in any amount and at any time until the fifth
anniversary of the issuance of the warrants. Upon transfer by DoCoMo to a third
party, or if DoCoMo converts its New Wireless tracking stock into AT&T Wireless
Group tracking stock, each of the warrants will be exercisable for 500 shares of
AT&T Wireless Group tracking stock at an exercise price of $35 per share, and
will no longer be exercisable for New Wireless tracking stock. After the
proposed spin-off, each warrant will be exercisable for 500 shares of the AT&T
Wireless Services common stock at an exercise price of $35 per share, subject to
adjustments to reflect the exchange ratio and customary anti-dilution
adjustments. The warrants are subject to the transfer restrictions described
below.

DoCoMo Investment Rights and Obligations

     In addition to the rights inherent in the shares of New Wireless tracking
stock, under the final agreements DoCoMo will have additional rights and
obligations with respect to its investment in AT&T Wireless Group that will
continue even if DoCoMo converts its shares of New Wireless tracking stock into
AT&T Wireless Group tracking stock or if the spin-off is completed.

     - Transfer Restrictions.  Without the consent of AT&T before the spin-off,
       or AT&T Wireless Services after the spin-off, for 18 months following the
       investment, DoCoMo may not transfer any warrants or any shares of AT&T
       Wireless Group tracking stock or AT&T Wireless Services common stock that
       it receives on conversion of New Wireless tracking stock, except if
       specified events occur. Those events are:

        -- a sale of all or substantially all of AT&T Wireless Group's assets or
           business through merger or other business combination, unless AT&T
           Wireless Group shareholders continue to own two-thirds of the
           successor corporation;

        -- the acquisition or acquisitions of business or assets, other than
           radio spectrum rights, by AT&T Wireless Group totaling more than $25
           billion; or

        -- a tender offer or exchange offer approved by the AT&T board of
           directors or AT&T Wireless Services board of directors, as
           applicable.

     In addition, subject to a limited exception, without AT&T's or AT&T
Wireless Group's consent, as the case may be, DoCoMo may not transfer any AT&T
Wireless Group securities to any person if after the transfer the recipient's
interest in AT&T Wireless would exceed 6%, or in the case of recipients,
principally financial institutions, who are eligible to report their interest on
Schedule 13G under the Securities Exchange Act, 10%.

                                       41
<PAGE>   48

     None of DoCoMo's special rights will be transferable by DoCoMo along with
the shares, except that DoCoMo may transfer its demand registration rights
described below to any transferee of more than $1 billion of AT&T Wireless Group
securities, and DoCoMo may transfer one demand registration right to a
transferee of the warrants. Any transfer of registration rights will be subject
to overall limitations on the registration rights and will not increase AT&T's
or AT&T Wireless Group's aggregate registration obligations.

     - Repurchase Obligations.  If the spin-off is not completed by January 1,
       2002, or March 15, 2002 if the reason it was not completed by January 1,
       2002 was that the requisite tax ruling from the Internal Revenue Service
       had not been received and AT&T reasonably believes that it is possible to
       obtain such a ruling by, or effect the spin-off without a ruling by,
       March 15, 2002 and is continuing to seek such a ruling or to effect the
       spin-off without a ruling, then DoCoMo may require AT&T to repurchase the
       New Wireless tracking stock, or AT&T Wireless Group tracking stock, and
       warrants, that DoCoMo still holds at that time. DoCoMo must exercise this
       right within 30 days of the January 1 or March 15, 2002 trigger date,
       whichever is applicable. The repurchase price will be DoCoMo's original
       purchase price plus a predetermined rate. In lieu of receiving this
       repurchase price from AT&T, DoCoMo will have the right to cause AT&T to
       register for public sale all of the shares of AT&T Wireless Group
       tracking stock (including shares that DoCoMo would hold if it exercised
       its warrants and converted its shares of New Wireless tracking stock),
       and thereafter DoCoMo will be able to sell such shares and retain the
       proceeds from that sale or sales. In some circumstances, if AT&T Wireless
       Group fails to launch service based on a wireless communications
       technology known as UMTS or W-CDMA, or wideband code division multiple
       access, in at least 13 of the top 50 U.S. markets by June 30, 2004 or
       abandons W-CDMA as its primary technology, DoCoMo may require AT&T before
       the proposed spin-off, or AT&T Wireless Services after the spin-off, to
       repurchase the warrants and New Wireless tracking stock, or AT&T Wireless
       Group tracking stock, that DoCoMo still holds (or the AT&T Wireless
       Services common stock and related warrants if post-spin). The repurchase
       price will be DoCoMo's original purchase price plus interest of a
       predetermined rate. In lieu of paying all or a portion of the repurchase
       price, AT&T or AT&T Wireless Services, as the case may be, will have the
       right to cause DoCoMo to sell any portion of its shares in a registered
       sale, and to pay DoCoMo the difference between the repurchase price and
       the proceeds from the registered sales.

     - Standstill.  Until the fifth anniversary of the closing of the investment
       agreement, DoCoMo, its controlled subsidiaries, when acting on behalf of
       DoCoMo, its officers, directors or agents, or any subsidiary to which
       DoCoMo has disclosed confidential information regarding its investment
       may not take a number of actions, including the following, without AT&T's
       consent before the spin-off or AT&T Wireless Services' consent after the
       spin-off:

        -- acquire or agree to acquire any voting securities of AT&T or AT&T
           Wireless Services, except in connection with DoCoMo's exercise of its
           preemptive rights, conversion rights, or warrants;

        -- solicit proxies with respect to AT&T's or AT&T Wireless Services'
           voting securities or become a participant in any election contest
           relating to the election of the directors of AT&T or AT&T Wireless
           Services;

        -- call or seek to call a meeting of the AT&T or AT&T Wireless Services
           shareholders or initiate a shareholder proposal;

        -- contest the validity of the standstill in a manner that would lead to
           public disclosure;

        -- form or participate in a group that would be required to file a
           Schedule 13D with the SEC as a "person" within the meaning of the
           Section 13(d)(3) of the Securities Exchange Act; or

        -- act in concert with any person for the purpose of effecting a
           transaction that would result in a change of control of AT&T or AT&T
           Wireless Services.

     After the fifth year anniversary of the investor agreement, DoCoMo will
continue to be subject to the standstill for so long as DoCoMo has the right to
nominate at least one director. However, DoCoMo will be released from the
standstill ninety-one days after the resignations of all of its representatives
on AT&T's and

                                       42
<PAGE>   49

AT&T Wireless Services' board of directors, as the case may be, all of DoCoMo's
nominated AT&T Wireless Services committee members and all of DoCoMo's nominated
management. After these resignations, AT&T Wireless may take steps to terminate
or sequester all of the other DoCoMo nominated employees.

     If NTT, which owns approximately two-thirds of DoCoMo, or any of NTT's
subsidiaries other than DoCoMo takes any action contrary to the standstill
restrictions and the action leads to any vote of shareholders of AT&T before the
spin-off or AT&T Wireless Services after the spin-off, then DoCoMo either must
vote its shares as the board of directors of AT&T or AT&T Wireless Services
directs, or must vote its shares in proportion to the votes cast by the
shareholders who are not affiliated with either DoCoMo or NTT. In addition, if
NTT or any of its subsidiaries commences a tender offer for AT&T or AT&T
Wireless Services securities, DoCoMo cannot tender or transfer any of its
securities into that offer until all of the conditions to that offer have been
satisfied.

     The standstill provisions described above will terminate in the following
circumstances:

        -- a third party unaffiliated with AT&T Wireless commences a tender or
           exchange offer of 15% of AT&T Wireless Services' outstanding voting
           securities and AT&T Wireless Services does not publicly recommend
           that its shareholders reject to the offer;

        -- AT&T Wireless Services enters into a definitive agreement to merge
           into or sell all or substantially all of its assets to a third party,
           unless AT&T Wireless Services shareholders retain at least 50% of the
           economic and voting power of the surviving corporation; or

        -- AT&T Wireless Services enters into a definitive agreement that would
           result in any one person or groups of persons acquiring more than 35%
           of the voting power of AT&T Wireless Services, unless, among other
           things, this person or group agrees to a standstill.

     The standstill provisions terminate with respect to AT&T two years after
the proposed spin-off (or, if sooner, upon any of the foregoing three events as
applied to AT&T).

     - Registration Rights.  Subject to certain exceptions and conditions,
       DoCoMo is entitled to require AT&T prior to the spin-off, and AT&T
       Wireless Services after the spin-off, to register shares of AT&T Wireless
       Group tracking stock or AT&T Wireless Services common stock on up to six
       occasions, with each demand involving not less than $500 million worth of
       shares. DoCoMo cannot exercise more than one demand right in any seven
       and a half month period. DoCoMo is also entitled to require AT&T or AT&T
       Wireless Services, as the case may be, to register securities for resale
       in an unlimited number of incidental registrations, commonly known as
       piggy-back registrations. DoCoMo will cease to be entitled to these
       registration rights if it owns less than $1 billion of AT&T or AT&T
       Wireless Services securities, as the case may be, and less than 2% of the
       outstanding economic interest in AT&T Wireless Services.

     - Board Representation.  Until the proposed spin-off, DoCoMo will be
       entitled to nominate one representative to the AT&T board of directors,
       and that representative will also be a member of the AT&T Wireless Group
       Capital Stock Committee. After the proposed spin-off, DoCoMo will be
       entitled to nominate a number of representatives on the AT&T Wireless
       Services board proportional to its economic interest acquired as a result
       of this investment. The DoCoMo nominees for these board seats must be
       senior officers of DoCoMo that are reasonably acceptable to AT&T or AT&T
       Wireless Services, as the case may be. DoCoMo will lose these board
       representation rights if its economic interest in AT&T Wireless Services
       falls below 10% for 60 consecutive days. However, as long as it retains
       62.5% of the shares of its original investment or shares of AT&T Wireless
       Group tracking stock into which such shares are convertible, DoCoMo will
       lose its board representation rights only if its economic interest in
       AT&T Wireless Services falls below 8% for 60 consecutive days.

     - Management Rights.  Before the spin-off, DoCoMo is entitled to appoint
       one of its senior executives that is reasonably acceptable to AT&T
       Wireless Group to AT&T Wireless Group's Senior Leadership Team. In
       addition, subject to AT&T Wireless Group's reasonable approval, DoCoMo
       can appoint between two and five of its employees as employees of AT&T
       Wireless Group, including the Manager-

                                       43
<PAGE>   50

       Finance and Director of Technology. DoCoMo will lose these rights under
       the same circumstances as it would lose board representation rights.

     - Right to Approve Specified Actions.  Prior to the spin-off, AT&T may not
       take any of the following actions without DoCoMo's prior approval:

        -- sell all or substantially all of AT&T Wireless Group's assets;

        -- sell all or substantially all of AT&T Wireless Group's business
           through merger or other business combination, unless AT&T Wireless
           Group shareholders retain two-thirds of the successor corporation;

        -- acquire business or assets for AT&T Wireless Group, other than radio
           spectrum rights, in excess of $17 billion;

        -- subject to some exceptions, issue any further economic interests or
           rights to AT&T Wireless over 15% of AT&T Wireless Group's market
           capitalization as of the date of the letter agreement;

        -- subject to some exceptions, pay cash dividends to or repurchase AT&T
           Wireless Group tracking stock;

        -- amend the articles of incorporation or by-laws of AT&T so that the
           rights of the holders of New Wireless tracking stock would be
           adversely affected; or

        -- change the spin-off related agreements so that AT&T Wireless Services
           would be materially adversely affected or enter into new, material
           contracts among affiliated parties that do not have arm's length
           terms.

     After the spin-off, DoCoMo, AT&T Wireless Services may not take any of the
following actions without DoCoMo's prior approval:

        -- change the scope of its business such that AT&T Wireless Group's
           Businesses (including those in its business plan) cease to constitute
           the primary businesses of AT&T Wireless Services; or

        -- enter into a strategic alliance with another wireless operator so
           that the wireless operator would own more than 15% but less than 50%
           of the economic interest in AT&T Wireless Services.

     DoCoMo will lose these approval rights under the same circumstances as it
would lose board representation rights.

     - Preemptive Rights.  DoCoMo has limited preemptive rights that entitle it
       to maintain its ownership interest by purchasing shares in some new
       equity issuances by AT&T or AT&T Wireless Services. In the event of a new
       equity issuance of the type covered by the preemptive right, then:

        -- if DoCoMo held 12% or more of the economic interest of AT&T Wireless
           Services at the time of the new issuance, DoCoMo may purchase a
           number of additional shares that would bring DoCoMo's economic
           interest back up to 16%; and

        -- if DoCoMo held less than 12% of the economic interest of AT&T
           Wireless Services at the time of the new issuance, DoCoMo may
           purchase a number of additional shares that would maintain DoCoMo's
           economic interest at the level it was at just prior to the new
           issuance.

     In most cases, the purchase price for these additional shares will be the
issuance price. DoCoMo will lose these preemptive rights under the same
circumstances as it would lose board representation rights.

Strategic Alliance

     AT&T Wireless and DoCoMo plan to form a strategic alliance to develop the
next generation of mobile multimedia services on a global-standard, high-speed
wireless network. AT&T Wireless Services will create a new, wholly owned
subsidiary to provide multimedia content, applications and services over its
current network, as well as on new, high-speed wireless networks built to global
standards for "third generation" or 3G services. AT&T Wireless Services will
contribute, among other things, its PocketNet service and rights to content and
applications to the new multimedia subsidiary. Both AT&T Wireless Services and
DoCoMo plan to provide technical resources and support staffing. In addition,
AT&T Wireless Services will be able to license

                                       44
<PAGE>   51

from DoCoMo, without additional payment, certain rights to DoCoMo's "i-mode"
service and related technology.

     The strategic alliance is expected to enable AT&T Wireless Services and
DoCoMo to offer wireless services to customers throughout the United States and
Japan. In addition, each has agreed, subject to technical and commercial
feasibility, to recognize the other as its primary and preferred roaming partner
in the other party's home territory.

     AT&T and AT&T Wireless Services on the one hand, and DoCoMo on the other,
have agreed to certain non-competition commitments that restrict each other's
ability to provide mobile wireless services in Japan and the United States,
respectively. They have also agreed to limit the extent to which AT&T or AT&T
Wireless Services on the one hand, and DoCoMo on the other, will be able to
participate in certain mobile multimedia activities and investments in each
other's home territory. Any such restrictions on AT&T would terminate upon the
earlier of a spin-off of AT&T Wireless Services or exercise by DoCoMo of any
put, liquidation or registration right as a result of the non-occurrence of such
a spin-off. AT&T Wireless Services and DoCoMo will generally be bound by the
non-competition commitments until DoCoMo loses its board representation and
management rights, either due to any of the events described above (i.e., under
Board Representation and Management Rights) or due to voluntary relinquishment
of such rights by DoCoMo.

                              THIS EXCHANGE OFFER

BACKGROUND AND PURPOSE

     AT&T is making this exchange offer in connection with implementing our plan
to more widely distribute AT&T Wireless Group tracking stock to our
shareholders. We intend for this exchange offer to allow AT&T and our
shareholders to more fully realize the economic value arising from our ownership
of AT&T Wireless Group and to permit the retirement of AT&T common stock. In
addition, this exchange offer will give holders of AT&T common stock who desire
to increase their relative investment in AT&T Wireless Group the opportunity to
do so in a convenient manner. Shareholders that have an unrealized gain on their
shares of AT&T common stock would be able to increase their relative investment
in AT&T Wireless Group in a manner generally free of U.S. Federal income tax
consequences.

EXCHANGE OFFER

     The issuance of shares of AT&T Wireless Group tracking stock in this
exchange offer will increase the number of shares of AT&T Wireless Group
tracking stock outstanding and reduce the retained inter-group interest of AT&T
Common Stock Group. AT&T Common Stock Group's retained interest in AT&T Wireless
Group is currently approximately 84% of the economic value of AT&T Wireless
Group. Assuming that this exchange offer is fully subscribed, we expect to issue
a total of approximately           new shares of AT&T Wireless Group tracking
stock. After these shares of AT&T Wireless Group tracking stock are issued, we
expect that AT&T Common Stock Group's retained inter-group interest would
represent approximately    % of the economic value of AT&T Wireless Group,
approximately      % assuming completion of the DoCoMo strategic investment in
AT&T Wireless Group, or approximately      %, assuming the exercise by DoCoMo of
warrants that it will receive in AT&T Wireless Group.

     This exchange offer will provide holders of AT&T common stock with an
opportunity to increase, in a manner generally free of U.S. federal income tax
other than with respect to cash in lieu of fractional shares, their interest in
the economic value of AT&T Wireless Group by exchanging shares of AT&T common
stock for shares of AT&T Wireless Group tracking stock. Every holder of AT&T
common stock will be affected by this exchange offer, regardless of whether they
participate in this exchange offer, as described below:

     - Tender of All of Your Shares of AT&T Common Stock.  If you tender all of
       your shares of AT&T common stock in this exchange offer, and if all of
       your shares of AT&T common stock are accepted for exchange, you will have
       increased your interest in the economic value of AT&T Wireless Group.
       However, you will no longer participate in any change in value of the
       AT&T common stock because you will no longer own any shares of AT&T
       common stock.

     - Tender of Some, But Not All, of Your Shares of AT&T Common Stock.  If you
       exchange some, but not all, of your shares of AT&T common stock in this
       exchange offer, you will generally have an increased interest in the
       economic value of AT&T Wireless Group, and a diminished interest in the
       economic value of AT&T's businesses other than AT&T Wireless Group,
       assuming that you exchange a greater percentage of your shares of AT&T
       common stock than the percentage of all outstanding shares of AT&T common
       stock that are exchanged in this exchange offer.

     - Tender of None of Your Shares of AT&T Common Stock.  If you do not tender
       any of your shares of AT&T common stock in this exchange offer, you will
       continue to own the same number of shares of AT&T common stock. You will
       continue to participate in any change in the value of AT&T common stock.
       However, as a result of the decrease in the inter-group retained interest
       owned by AT&T Common Stock Group, you will have a diminished interest in
       the economic value of AT&T Wireless Group.

     All shares of AT&T common stock tendered in this exchange offer will be
cancelled and become authorized and unissued shares of AT&T common stock. This
means that these shares of AT&T common stock will generally be available for
issuance by AT&T without further shareholder action, except as may be required
by applicable law or the rules of the NYSE, for general or other corporate
purposes, including stock splits and dividends, acquisitions, the raising of
additional capital for use in AT&T's businesses and pursuant to employee benefit
plans.

RELATIONSHIP TO AT&T'S RESTRUCTURING PLAN

     If AT&T's restructuring plan is completed, holders of shares of AT&T common
stock who retain their shares of AT&T common stock would receive shares
representing interests in AT&T's major business units: AT&T Wireless, AT&T
Business, AT&T Broadband and AT&T Consumer. To the extent that your shares of
AT&T common stock are tendered and accepted in this exchange offer, your
relative interest in AT&T Wireless Group will be increased but your relative
interest in the remaining AT&T business units will be decreased and you will not
receive shares in the other business units for your shares of AT&T common stock
that you tender in this exchange offer.

     Conversely, all holders of shares of AT&T common stock are expected to
receive shares of the AT&T Wireless Services common stock in mid 2001 if it
becomes an independent company. Even if you do not tender any shares of AT&T
common stock in this exchange offer, if you retain your shares of AT&T common
stock we expect that you would receive some shares in the AT&T Wireless Services
common stock at that time. However, your interest in AT&T Wireless Services
would be smaller than it would be if your shares of AT&T common stock are
tendered and accepted in this exchange offer.

     We cannot predict what the relative value of the shares representing
interests in AT&T Wireless, AT&T Business, AT&T Broadband and AT&T Consumer will
be over time. As a result, we cannot tell whether the securities you would own
if you tender shares of AT&T common stock in this exchange offer will be worth
more or less at any point in the future than the securities you would own if you
do not tender your shares of AT&T common stock.

NO APPRAISAL RIGHTS

     Appraisal is a statutory remedy available to shareholders of corporations
that object to certain mergers and other extraordinary and statutorily specified
corporate actions. No appraisal rights are or will be available to holders of
AT&T common stock or AT&T Wireless Group tracking stock in connection with this
exchange offer.

REGULATORY APPROVALS

     No filings under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, are required in connection with this exchange offer generally. If a
shareholder decides to participate in this exchange offer and consequently
acquires enough shares of AT&T Wireless Group tracking stock to exceed any
threshold stated in the regulations under the HSR Act, and if an exemption under
those regulations does not apply, that shareholder and AT&T could be required to
make filings under the HSR Act, and the waiting period under the HSR Act would
have to expire or be terminated before any exchanges of shares with such
stockholder could be effected. A filing requirement could delay exchanges with
that shareholder for several months or more.

ACCOUNTING TREATMENT

     The shares of AT&T common stock which we receive in this exchange offer
will be recorded as a decrease in AT&T's shareholders' equity in an amount equal
to the market value, as of the expiration date, of the shares of AT&T Wireless
Group tracking stock issued in this exchange offer. This issuance of AT&T
Wireless Group tracking stock will be recorded as an equal and offsetting
increase in AT&T's shareholders' equity. Accordingly, except for the direct
costs of this exchange offer, this exchange offer will not affect the financial
position of AT&T. As a result of this exchange offer, basic and diluted earnings
per share calculations for the AT&T common stock after the expiration date will
reflect the lower number of outstanding shares of AT&T common stock and the AT&T
common shareholders' decreased interest in the available separate combined net
income of AT&T Wireless Group. While the earnings per share for AT&T Wireless
Group tracking stock will not change, basic and diluted earnings per share
calculations for the AT&T Wireless Group tracking stock after the expiration
date will reflect AT&T Wireless Group tracking shareholders' increased interest
in the available separate combined net income of AT&T Wireless Group and the
proportionate increase in the number of shares of AT&T Wireless Group tracking
stock outstanding.

     AT&T's issuance of shares of AT&T Wireless Group tracking stock in this
exchange offer will not, in and of itself, affect the financial position or
results of operations of AT&T Wireless Group.

TERMS OF THIS EXCHANGE OFFER

     AT&T is offering to exchange           shares of AT&T Wireless Group
tracking stock for each share of AT&T common stock that is validly tendered on
the terms and subject to the conditions described below by 12:00 midnight, New
York City time, on           , 2001. AT&T may extend this deadline for any
reason, including under those circumstances specified below. The last day on
which tenders will be accepted, whether on           , 2001 or any later date to
which this exchange offer may be extended, is sometimes referred to in this
document as the "expiration date." This is a voluntary exchange offer, which
means that holders of AT&T common stock may tender all, some or none of their
shares of AT&T common stock in this exchange offer, subject to proration. All
persons holding AT&T common stock are eligible to participate in this exchange
offer if they validly tender their shares of AT&T common stock during the
exchange offer period in a jurisdiction where this exchange offer is permitted
under the laws of that jurisdiction.

     AT&T will accept up to           shares of AT&T common stock for exchange
and will issue up to           shares of AT&T Wireless Group tracking stock in
this exchange offer. If more than           shares of AT&T common stock are
validly tendered, the tendered shares will be subject to proration when this
exchange offer expires. AT&T's obligation to complete this exchange offer is
subject to important conditions that are described under "-- Conditions for
Completion of this Exchange Offer".

     In determining the exchange ratio, AT&T considered, among other things:

     - recent market prices and volatility on the NYSE for shares of AT&T common
       stock and AT&T Wireless Group tracking stock; and

     - advice from the dealer manager as to what exchange ratio might attract
       holders of AT&T common stock to participate in this exchange offer.

     AT&T will furnish this document and related documents to brokers, banks and
similar persons whose names or the names of whose nominees appear on AT&T's
shareholder list or, if applicable, who are listed as participants in a clearing
agency's security position listing for subsequent transmittal to beneficial
owners of shares of AT&T common stock.

     The terms and conditions of this exchange offer are set forth in this
document, the letter of transmittal and the instructions to the letter of
transmittal. Each holder of AT&T common stock who tenders shares of AT&T common
stock in this exchange offer will be agreeing to the terms and conditions of
this exchange offer and will be making certain representations and warranties to
and agreements with AT&T, as described in these documents. We urge you to read
these documents carefully before deciding whether to participate in this
exchange offer.

NO RECOMMENDATION

     None of AT&T, the exchange agent, the information agent, the dealer manager
or the marketing manager or any of their respective officers or directors makes
any recommendation as to whether you should participate in this exchange offer.

PRORATION; TENDERS FOR EXCHANGE BY HOLDERS OF FEWER THAN 100 SHARES OF AT&T
COMMON STOCK

     If, upon the expiration date, holders of AT&T common stock have validly
tendered more than           shares of AT&T common stock so that more than
          shares of AT&T Wireless Group tracking stock would be issued in this
exchange offer, we will accept on a pro rata basis, all shares of AT&T common
stock validly tendered and not withdrawn, with appropriate adjustments to avoid
the return of fractional shares of AT&T common stock, except as described below.

     Except as otherwise provided in this paragraph, holders of an aggregate of
less than 100 shares of AT&T common stock at the close of business one trading
day prior to the date the exchange ratio is established that validly tender all
of their shares of AT&T common stock will not be subject to proration if this
exchange offer is oversubscribed. Shares of AT&T common stock held in an AT&T
savings plan are not eligible for this preferential treatment. Beneficial
holders of 100 or more shares of AT&T common stock are not eligible for

                                       48
<PAGE>   55

this preferential treatment, even if these holders have separate stock
certificates or accounts representing fewer than 100 shares of AT&T common
stock. If you own fewer than 100 shares of AT&T common stock and wish to take
advantage of the preferential treatment of odd-lot shares in the event of
proration, you must tender all of your shares of AT&T common stock in this
exchange offer.

     We expect to announce preliminary results of this exchange offer by press
release promptly after the expiration date. However, because of the time
required and difficulty involved in determining the number of shares of AT&T
common stock validly tendered for exchange, AT&T expects that the final results,
including proration, if any, will not be determined until up to about ten
business days after the expiration date. We will announce the final results of
this exchange offer by press release promptly after such results have been
determined.

EXCHANGE OF SHARES OF AT&T COMMON STOCK

     If all of the conditions of this exchange offer are satisfied or waived,
AT&T will exchange           shares of AT&T Wireless Group tracking stock for
each validly tendered share of AT&T common stock that was not properly withdrawn
prior to the expiration date, except as described under "-- Proration; Tenders
for Exchange by Holders of Fewer than 100 Shares of AT&T Common Stock" and
"-- Extension of Tender Period; Termination; Amendment." AT&T may, subject to
the rules under the Securities Exchange Act, delay accepting or exchanging any
shares of AT&T common stock in order to comply, in whole or in part, with any
applicable law. For a description of AT&T's right to delay, terminate or amend
this exchange offer, see "-- Extension of Tender Period; Termination;
Amendment."

     If AT&T notifies the exchange agent, either orally or in writing, that it
has accepted the tenders of shares of AT&T common stock for exchange, the
exchange of these shares of AT&T common stock will be complete. Promptly
following the announcement by AT&T of the final results of this exchange offer,
including proration, if any, the exchange agent will deliver the tendered shares
of AT&T common stock to AT&T. Simultaneously, the exchange agent, as agent for
the tendering shareholders, will receive from AT&T the shares of AT&T Wireless
Group tracking stock that correspond, based on the exchange ratio and taking
into account proration, to the number of shares of AT&T common stock accepted.
The exchange agent will then credit the shares of AT&T Wireless Group tracking
stock, including fractional shares, to book-entry accounts maintained by AT&T's
transfer agent for the benefit of the tendering holders.

     If any tendered shares of AT&T common stock are not exchanged for any
reason, or if fewer shares of AT&T common stock are exchanged due to proration,
these unexchanged or untendered shares of AT&T common stock will be returned to
the tendering holders through a credit to book-entry accounts maintained by
AT&T's transfer agent for the benefit of the holders.

     As soon as reasonably practicable following the crediting of shares to your
respective book-entry accounts, AT&T's transfer agent will send you an account
statement evidencing your holdings.

     AT&T will not pay any interest in connection with this exchange offer,
regardless of any delay in making the exchange or crediting or delivering
shares.

     No alternative, conditional or contingent tenders will be accepted in this
exchange offer. Tendering shareholders waive any right to receive notice of the
acceptance by AT&T of their shares of AT&T common stock for exchange.

PROCEDURES FOR TENDERING SHARES OF AT&T COMMON STOCK

     To tender your shares of AT&T common stock, you must complete the following
procedures so that your tender is received by the exchange agent before the
expiration date:

     If you have stock certificates representing your shares of AT&T common
stock, you should send the following documents to the exchange agent by one of
the mailing methods described in the letter of

                                       49
<PAGE>   56

transmittal, at the applicable address set forth on the back cover of this
document sufficiently in advance of the expiration date for them to be received
by the exchange agent before the expiration date:

     - a properly completed and executed letter of transmittal indicating the
       number of shares of AT&T common stock to be tendered and any other
       documents required by the instructions to the letter of transmittal; and

     - the physical stock certificates representing the shares of AT&T common
       stock to be tendered.

     In addition, the stock certificates representing shares of AT&T common
stock to be tendered must be endorsed or you must enclose an appropriate stock
power if:

     - a stock certificate representing shares of AT&T common stock to be
       tendered is registered in the name of a person other than the signer of a
       letter of transmittal;

     - delivery of shares of AT&T Wireless Group tracking stock is to be made to
       the exchange agent on behalf of a person other than the registered owner
       of the shares of AT&T common stock being tendered; or

     - shares of AT&T common stock not accepted for exchange are to be delivered
       to AT&T's transfer agent on behalf of a person other than the registered
       owner.

     The signature on the letter of transmittal must be guaranteed by an
eligible institution unless the shares of AT&T common stock tendered under the
letter of transmittal are tendered in one of the following ways:

     - by the registered holder of the shares of AT&T common stock tendered if
       the holder has not requested special issuance as described in "Special
       Issuance Instructions" of the instructions to the letter of transmittal;
       or

     - for the account of an eligible institution.

An eligible institution is a member of a registered national securities exchange
or a member of the National Association of Securities Dealers, Inc. or a
commercial bank or trust company having an office or a correspondent in the
United States. Most banks and financial institutions are eligible institutions.

     If your stock certificate representing shares of AT&T common stock has been
lost, destroyed, mutilated or stolen, see "-- Lost, Destroyed, Mutilated or
Stolen Certificates" for information regarding certain special procedures that
must be followed.

     The exchange agent's addresses are set forth on the back cover of this
document.

     If you hold your shares of AT&T common stock through a broker, you should
follow the instructions sent to you separately by your broker. You should not
use the letter of transmittal to direct the tender of your shares of AT&T common
stock. Your broker must notify The Depository Trust Company and cause it to
transfer the shares into the exchange agent's account in accordance with The
Depository Trust Company's procedures. The broker must also ensure that the
exchange agent receives an agent's message from The Depository Trust Company
confirming the book-entry transfer of your shares of AT&T common stock. An
agent's message is a message, transmitted by The Depository Trust Company and
received by the exchange agent, that forms a part of a book-entry confirmation,
which states that The Depository Trust Company has received an express
acknowledgment from the participant in The Depository Trust Company tendering
the shares that such participant has received and agrees to be bound by the
terms of the letter of transmittal and the instructions to the letter of
transmittal.

     If you are an institution that is a participant in The Depository Trust
Company's book-entry transfer facility, you should follow the same procedures
that are applicable to persons holding shares through a broker as described in
the immediately preceding paragraph.

     If you hold your shares of AT&T common stock as a participant in AT&T's
Dividend Reinvestment Plan or in book-entry form with the AT&T transfer agent
through the direct registration system, you should send a properly completed and
executed letter of transmittal indicating the number of shares of AT&T common
stock to be tendered and any other documents required by the instructions to the
letter of transmittal to the exchange agent by one of the mailing methods
described on the letter of transmittal at the applicable address

                                       50
<PAGE>   57

set forth on the back cover of this document sufficiently in advance of the
expiration date for them to be received by the exchange agent before the
expiration date. If you tender all of your shares of AT&T common stock that you
hold in AT&T's Dividend Reinvestment Plan, that tender will constitute
termination of your participation in AT&T's Dividend Reinvestment Plan.

     If you hold your shares of AT&T common stock as a participant in an AT&T or
an AT&T affiliated company savings plan, you should follow the instructions sent
to you separately by the plan trustees or administrator of the plan. You should
not use the letter of transmittal to direct the tender of your shares of AT&T
common stock held in that plan.

     The AT&T savings plans eligible to participate in this exchange offer

     Trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity who
sign the letter of transmittal, notice of guaranteed delivery or any stock
certificates representing shares of AT&T common stock to be tendered or stock
powers must indicate the capacity in which they are signing, and must submit
evidence, which is current as of a date within 180 days prior to the date that
the letter of transmittal is delivered to the exchange agent, of their power to
act in that capacity, unless this requirement is waived by AT&T.

     If you validly tender your shares of AT&T common stock and those shares are
accepted by AT&T, there will be a binding agreement between you and AT&T on the
terms and subject to the conditions set forth in this document and in the letter
of transmittal and the instructions to the letter of transmittal. A person who
tenders shares of AT&T common stock for their own account violates U.S. federal
securities law unless the person owns:

     - those shares of AT&T common stock;

     - other securities convertible into or exchangeable for those shares of
       AT&T common stock and intends to acquire shares of AT&T common stock for
       tender by conversion or exchange of such securities; or

     - an option, warrant or right to purchase those shares of AT&T common stock
       and intends to acquire shares of AT&T common stock for tender by exercise
       of that option, warrant or right.

U.S. federal securities law provides a similar restriction applicable to the
tender or guarantee of a tender on behalf of another person.

     Do not send letters of transmittal, certificates representing shares of
AT&T common stock or other exchange offer documents to AT&T, the AT&T Wireless
Group, the dealer manager, the marketing manager or the information agent. These
materials must be submitted to Equiserve, the exchange agent, at one of the
addresses set forth on the back cover of this document as described above and in
the instructions to the letter of transmittal in order for you to participate in
this exchange offer.

     It is up to you to decide how to deliver your shares of AT&T common stock
and all other required documents to the exchange agent. It is your
responsibility to ensure that all necessary materials are received by the
exchange agent prior to the expiration date. If the exchange agent does not
receive all of the materials

                                       51
<PAGE>   58

required by this section at one of the addresses set forth on the back cover of
this document before the expiration date, your shares of AT&T common stock will
not be validly tendered in this exchange offer.

AT&T'S INTERPRETATIONS ARE BINDING

     AT&T will determine, in its sole and absolute discretion, all questions as
to the form of documents, including notices of withdrawal, and the validity,
form, eligibility, including time of receipt, and acceptance for exchange of any
tender of shares of AT&T common stock in this exchange offer. This determination
will be final and binding on all tendering shareholders.

     AT&T reserves the absolute right to:

     - determine whether a tendering shareholder is eligible;

     - reject any and all tenders of any shares of AT&T common stock not validly
       tendered or the acceptance of which, in the opinion of AT&T's counsel,
       may be unlawful;

     - waive any defects or irregularities in the tender of shares of AT&T
       common stock or any conditions of this exchange offer either before or
       after the expiration date; and

     - request any additional information from any record or beneficial owner of
       shares of AT&T common stock that AT&T deems necessary or appropriate.

None of AT&T, the information agent, the exchange agent, the dealer manager, the
marketing manager, the soliciting dealers or any other person will be under any
duty to notify tendering shareholders of any defect or irregularity in tenders
or notices of withdrawal or incur any liability for failure to give such
notification. It is your responsibility to ensure that your shares of AT&T
common stock are validly tendered in accordance with the procedures described in
this document and the related documents prior to the expiration date.

LOST, DESTROYED, MUTILATED OR STOLEN CERTIFICATES

     If your stock certificate representing shares of AT&T common stock has been
lost, destroyed, mutilated or stolen and you wish to tender your shares of AT&T
common stock, please complete Box A of the accompanying letter of transmittal.
You will need to enclose a check payable to the surety company in the amount
needed to pay for a surety bond for your lost, destroyed, mutilated or stolen
shares of AT&T common stock and any other applicable procedures. The surety bond
amount will be $     per share, with a minimum surety bond amount of $
in all cases. Upon receipt of the surety bond payment and a properly completed
letter of transmittal, including Box A, your shares of AT&T common stock will be
validly tendered in this exchange offer.

GUARANTEED DELIVERY PROCEDURES

     If you wish to tender your shares of AT&T common stock but the shares are
not immediately available, or time will not permit the shares of AT&T common
stock or other required documentation to reach the exchange agent before the
expiration date, you may still tender your shares of AT&T common stock if:

     - the tender is made through an eligible institution;

     - the exchange agent receives from the eligible institution before the
       expiration date, a properly completed and duly executed notice of
       guaranteed delivery, substantially in the form provided by AT&T; and

     - the exchange agent receives the stock certificates for all physically
       tendered shares of AT&T common stock, in proper form for transfer and a
       properly completed letter of transmittal, or a facsimile of a letter of
       transmittal and all other documents required by the letter of transmittal
       and the instructions to the letter of transmittal, within three NYSE
       trading days after the date of execution of the notice of guaranteed
       delivery.

     You may deliver the notice of guaranteed delivery by hand, facsimile
transmission or mail to the exchange agent at the applicable address set forth
on the back cover of this document and you must include a guarantee by an
eligible institution in the form set forth in the notice of guaranteed delivery.

                                       52

WITHDRAWAL RIGHTS

     You may withdraw tenders of shares of AT&T common stock at any time prior
to the expiration date, and, unless AT&T has accepted your tender as provided in
this document and the accompanying documents, after the expiration of 40
business days from the commencement of this exchange offer. If AT&T:

     - delays its acceptance of shares of AT&T common stock for exchange,

     - extends this exchange offer, or

     - is unable to accept shares of AT&T common stock for exchange under this
       exchange offer for any reason,

then, without prejudice to AT&T's rights under this exchange offer, the exchange
agent may, on behalf of AT&T, retain shares of AT&T common stock tendered, and
these shares of AT&T common stock may not be withdrawn, except as otherwise
provided in this document and the accompanying documents, subject to provisions
under the Exchange Act that provide that an issuer making an exchange offer
shall either pay the consideration offered or return tendered securities
promptly after the termination or withdrawal of the exchange offer.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent at one of its addresses set forth on the back
cover of this document. The notice of withdrawal must:

     - specify the name of the person having tendered the shares of AT&T common
       stock to be withdrawn;

     - identify the number of shares of AT&T common stock to be withdrawn; and

     - specify the name in which physical AT&T common stock certificates are
       registered, if different from that of the withdrawing holder.

     If stock certificates representing the shares of AT&T common stock have
been delivered or otherwise identified to the exchange agent, then, before the
release of these certificates, the withdrawing holder must also submit the
serial numbers of the particular stock certificates to be withdrawn.

     If the shares of AT&T common stock have been tendered pursuant to the
procedures for book-entry transfer, any notice of withdrawal must specify the
name and number of the account at The Depository Trust Company to be credited
with the withdrawn shares of AT&T common stock and otherwise comply with the
procedures of The Depositary Trust Company.

     If the shares of AT&T common stock have been tendered pursuant to the
procedures applicable to participants in AT&T's Dividend Reinvestment Plan or
through book-entry transfer under the direct registration system, any notice of
withdrawal must specify the name and number of the account with AT&T's transfer
agent.

     Any shares of AT&T common stock withdrawn will be deemed not to have been
validly tendered for exchange for purposes of this exchange offer. Properly
withdrawn shares may be retendered by following one of the procedures described
under "-- Procedures for Tendering Shares of AT&T Common Stock" at any time on
or before the expiration date.

     If you withdraw your tender of any shares of AT&T common stock, these
shares will be credited to a book-entry account maintained by AT&T's transfer
agent on your behalf. However, any shareholder who wishes to receive a physical
stock certificate evidencing that shareholder's shares will be able to obtain a
certificate at no charge by contacting AT&T's transfer agent.

     Except as otherwise provided above, any tender of shares of AT&T common
stock made under this exchange offer is irrevocable. No alternative, conditional
or contingent tenders will be accepted in this exchange offer.

BOOK-ENTRY ACCOUNTS

     Physical stock certificates representing shares of AT&T Wireless Group
tracking stock or AT&T common stock will not be issued as a result of this
exchange offer. Rather than issuing physical stock

                                       53
<PAGE>   60

certificates representing either shares of AT&T common stock returned due to
proration or withdrawal or shares of AT&T Wireless Group tracking stock issued
in exchange for shares of AT&T common stock tendered in this exchange offer, the
exchange agent will credit these shares to book-entry accounts maintained by
AT&T's transfer agent for the benefit of the respective holders. This method of
holding stock eliminates the need for actual stock certificates to be issued and
eliminates the requirements for physical movement of stock certificates at the
time of sale. As soon as reasonably practicable following the crediting of
shares to your respective book-entry accounts, you will receive an account
statement from AT&T's transfer agent evidencing your holdings, as well as
general information on the book-entry form of ownership through AT&T's direct
registration system. For more information about the book-entry form of ownership
under AT&T's direct registration system, see "Description of AT&T Wireless Group
Tracking Stock -- Direct Registration System."

     You are not required to maintain a book-entry account and you may at any
time obtain a physical stock certificate for all or a portion of your shares of
AT&T Wireless Group tracking stock received as part of this exchange offer at no
cost to you. Instructions describing how you can obtain stock certificates will
be included with the account statement mailed to you and can also be obtained
upon request from AT&T's transfer agent.

EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT

     AT&T expressly reserves the right, in its sole and absolute discretion, for
any reason, including the non-satisfaction of any of the conditions for
completion set forth below, at any time and from time to time, to extend the
period of time during which this exchange offer is open or to amend this
exchange offer in any respect, including changing the exchange ratio. AT&T also
expressly reserves the right to extend the period of time during which this
exchange offer is open in the event this exchange offer is undersubscribed
-- that is, fewer than      shares of AT&T common stock are tendered. In any of
these cases, AT&T will make a public announcement of the extension or amendment.

     If AT&T materially changes the terms of or information concerning this
exchange offer, AT&T will extend this exchange offer. Depending on the substance
and nature of the change, we will extend the offer for at least five to ten
business days following the announcement if this exchange offer would have
otherwise expired within such five to ten business days.

     If any condition for completion of this exchange offer described below is
not satisfied, AT&T reserves the right to choose to delay acceptance for
exchange of any shares of AT&T common stock or to terminate this exchange offer
and not accept for exchange any shares of AT&T common stock. For more
information, see "-- Conditions for Completion of this Exchange
Offer -- Consequences of Unsatisfied Conditions."

     If AT&T extends this exchange offer, is delayed in accepting any shares of
AT&T common stock or is unable to accept for exchange any shares of AT&T common
stock under this exchange offer for any reason, then, without affecting AT&T's
rights under this exchange offer, the exchange agent may, on behalf of AT&T,
retain all shares of AT&T common stock tendered. These shares of AT&T common
stock may not be withdrawn except as provided under "-- Withdrawal Rights."
AT&T's reservation of the right to delay acceptance of any shares of AT&T common
stock is subject to applicable law, which requires that AT&T pay the
consideration offered or return the shares of AT&T common stock deposited
promptly after the termination or withdrawal of this exchange offer. Any shares
of AT&T common stock to be returned to you will be credited to a book-entry
account in your name maintained by AT&T's transfer agent. However, any
shareholder who wishes to receive a physical stock certificate evidencing that
shareholder's shares will be able to obtain a certificate at no charge by
contacting AT&T's transfer agent. Fractional shares will not be issued.

     AT&T will issue a press release or other public announcement no later than
9:00 a.m., New York time, on the next business day following any extension,
amendment, non-acceptance or termination of the previously scheduled expiration
date.

CONDITIONS FOR COMPLETION OF THIS EXCHANGE OFFER

     AT&T will not be obligated to complete this exchange offer unless at least
          shares of AT&T common stock are validly tendered and not withdrawn and
all of the other conditions to the exchange offer

<PAGE>   61

in this document as the "minimum condition" is designed to ensure that at least
       shares of AT&T Wireless Group tracking stock are issued under this
exchange offer.

     Even if the minimum condition is satisfied, AT&T may choose not to accept
shares of AT&T common stock for exchange and not to complete this exchange offer
if:

     - AT&T or AT&T Wireless Group does not receive or obtain any consent,
       authorization, approval or exemption of or from any governmental
       authority that may be advisable in connection with the completion of this
       exchange offer;

     - any action, proceeding or litigation seeking to enjoin, make illegal or
       delay completion of this exchange offer or otherwise relating in any
       manner to this exchange offer is instituted or threatened;

       governmental authority or other regulatory or administrative authority
       and is in effect, or any statute, rule, regulation, governmental order or
       injunction shall have been proposed, enacted, enforced or deemed
       applicable to this exchange offer, any of which would or might restrain,
       prohibit or delay completion of this exchange offer or impair the
       contemplated benefits of this exchange offer to AT&T or AT&T Wireless
       Group;

     - any of the following occurs and the adverse effect of such occurrence
       shall, in the judgment of AT&T, be continuing:

        -- any general suspension of trading in, or limitation on prices for,
           securities on any national securities exchange or in the
           over-the-counter market in the United States;

        -- any extraordinary or material adverse change in U.S. financial
           markets generally, including, without limitation, a decline of at
           least   % in any of the Dow Jones Average of Industrial Stocks, the
           Nasdaq Stock Market Composite Index or the Standard & Poor's 500
           Index from the close of the markets on                  , 2001;

        -- a declaration of a banking moratorium or any suspension of payments
           in respect of banks in the United States;

        -- any limitation, whether or not mandatory, by any governmental
           authority on, or any other event that would reasonably be expected to
           materially adversely affect, the extension of credit by banks or
           other lending institutions;

        -- a commencement of a war or other national or international calamity
           directly or indirectly involving the United States, which would
           reasonably be expected to affect materially and adversely, or to
           delay materially, the completion of this exchange offer; or

        -- if any of the situations described above existed at the time of
           commencement of this exchange offer, and AT&T determines that the
           situation has deteriorated materially subsequent to the time of
           commencement;

     - any tender or exchange offer, other than this exchange offer by AT&T,
       with respect to some or all of the outstanding AT&T Wireless Group
       tracking stock or AT&T common stock or any merger, acquisition or other
       business combination proposal involving AT&T or AT&T Wireless Group or a
       substantial portion of their respective assets, shall have been proposed,
       announced or made by any person or entity;

     - any event or events shall have occurred that have resulted or may result,
       in AT&T's judgment, in an actual or threatened change in the business
       condition, income, operations, stock ownership or prospects of AT&T and
       its subsidiaries, taken as a whole, or of AT&T Wireless Group and its
       subsidiaries, taken as a whole or that otherwise affects AT&T or AT&T
       Wireless Group or the trading prices of AT&T common stock or AT&T
       Wireless Group tracking stock; or

                                       55
<PAGE>   62

     - as the terms "group" and "beneficial owner" are used in Section 13(d) of
       the Exchange Act and SEC rules thereunder:

          -- any person, entity or group shall have become, directly or
             indirectly, the beneficial owner of more than 5% of the outstanding
             shares of AT&T common stock or AT&T Wireless Group tracking stock,
             other than a person, entity or group that had publicly disclosed
             that beneficial ownership by an appropriate filing with the SEC
             prior to                , 2001; or

          -- any such person, entity or group that had publicly disclosed such
             beneficial ownership prior to that date shall have become, directly
             or indirectly, the beneficial owner of additional AT&T common stock
             and AT&T Wireless Group tracking stock, the ownership of which was
             not publicly disclosed in such filing, constituting more than 2% of
             the outstanding shares of AT&T common stock and AT&T Wireless Group
             tracking stock; or

          -- any new group shall have been formed that beneficially owns more
             than 5% of the outstanding shares of AT&T common stock or AT&T
             Wireless Group tracking stock; or

          -- any one or more of the foregoing events relating to beneficial
             ownership would occur as a result of the issuance of AT&T Wireless
             Group tracking stock in exchange for any shares of AT&T common
             stock that have been tendered in this exchange offer;

the occurrence of which event, in the judgment of AT&T, in any case and
regardless of the circumstances, makes it inadvisable to proceed with this
exchange offer or with the acceptance of shares of AT&T common stock tendered
for exchange.

  Consequences of Unsatisfied Conditions

     If any condition to this exchange offer is not satisfied, subject to
applicable rules and regulations, AT&T may, in its sole and absolute discretion:

     - terminate this exchange offer and promptly return in book-entry form all
       tendered shares of AT&T common stock to tendering shareholders;

     - delay acceptance for exchange of any shares of AT&T common stock, extend
       this exchange offer and, subject to the withdrawal rights described under
       "-- Withdrawal Rights," retain all tendered shares of AT&T common stock
       until the expiration date;

     - amend the terms and conditions of this exchange offer; or

     - waive the unsatisfied condition and, subject to any requirement to extend
       the period of time during which this exchange offer is open, complete
       this exchange offer.

     These conditions are for the sole and exclusive benefit of AT&T. AT&T may
assert these conditions with respect to all or any portion of this exchange
offer regardless of the circumstances giving rise to them. AT&T may waive any
condition in whole or in part at any time in its sole and absolute discretion,
subject to applicable rules and regulations, AT&T's failure to exercise its
rights under any of the conditions described above does not represent a waiver
of these rights. Each right is an ongoing right which may be asserted at any
time. Any determination by AT&T concerning the conditions described above will
be final and binding upon all parties.

     If a stop order issued by the SEC is in effect at any time after the
commencement of this exchange offer with respect to the registration statement
of which this document is a part, AT&T will not accept any shares of AT&T common
stock tendered and will not exchange shares of the AT&T Wireless Group tracking
stock for any shares of AT&T common stock.

LEGAL LIMITATION

in the United States where making this exchange offer or its acceptance would

     AT&T will pay each soliciting dealer a solicitation fee of $     per share,
for up to 1,000 shares per tendering stockholder, for each share of AT&T common
stock tendered and accepted for exchange under this exchange offer if that
soliciting dealer has affirmatively solicited and obtained the tender. AT&T will
not pay a solicitation fee in connection with a tender of AT&T common stock by a
stockholder who tenders:

     - more than 10,000 shares of AT&T common stock; or

     - from a country outside the United States.

                                       57

"Soliciting dealer" includes the following organizations:

     - any broker or dealer in securities that is a member of any national
       securities exchange in the United States or of the National Association
       of Securities Dealers, Inc.; or

     - any bank or trust company located in the United States.

     In order for a soliciting dealer to receive a solicitation fee with respect
to the valid tender of shares of AT&T common stock held in registered form, the
exchange agent must have received, by three NYSE trading days after the
expiration date, a properly completed and duly executed letter of transmittal.
If a letter of transmittal is not received by the exchange agent within three
NYSE trading days after the expiration date, no solicitation fee will be paid to
such soliciting dealer.

     In order for a soliciting dealer to receive a solicitation fee with respect
to the valid tender of shares of AT&T common stock held beneficially, the
exchange agent must have received, by three NYSE trading days after the
expiration date, an agent's message. If an agent's message is not received by
the exchange agent within three NYSE trading days after the expiration date, no
solicitation fee will be paid to that soliciting dealer.

     Under no circumstances shall a fee be paid to a soliciting dealer more than
once with respect to any shares of AT&T common stock. No soliciting dealer is
required to make a recommendation to holders of shares of AT&T common stock as
to whether to tender or refrain from tendering in this exchange offer.

     Soliciting dealers should take care to ensure proper record-keeping to
document their entitlement to any solicitation fee. AT&T and the exchange agent
reserve the right to require additional information, as deemed warranted in
their sole discretion.

     All questions as to the validity, form, and eligibility, including time of
receipt of notices of solicited tenders will be determined by the exchange agent
and AT&T, in their sole discretion, which determination will be final and
binding. Neither AT&T, the exchange agent nor any other person will be under any
duty to give notification of any defects or irregularities in a notice of
solicited tender or incur any liability for failure to give such notification.

     AT&T will not pay a solicitation fee to a soliciting dealer who for any
reason must transfer the fee to a tendering stockholder. Soliciting dealers are
not entitled to a solicitation fee with respect to shares of AT&T common stock
beneficially owned by them or with respect to any shares that are registered in
the name of a soliciting dealer unless the shares are held by such soliciting
dealer as nominee and are tendered for the benefit of beneficial holders. No
broker, dealer, bank, trust company or fiduciary shall be deemed to be the agent
of AT&T, the exchange agent, the information agent or the dealer manager for
purposes of this exchange offer.

     AT&T will not pay any fees or commissions to any broker or dealer or any
other person, other than Credit Suisse First Boston, Lehman Brothers Inc. and
the soliciting dealers, for soliciting tenders of shares of AT&T common stock
under this exchange offer. Brokers, dealers, commercial banks and trust
companies will, upon request made within a reasonable period of time, be
reimbursed by AT&T for reasonable and necessary costs and expenses incurred by
them in forwarding materials to their customers.

INFORMATION AGENT AND EXCHANGE AGENT

     AT&T has retained Georgeson Shareholder Services to act as the information
agent and Equiserve to act as the exchange agent in connection with this
exchange offer. Equiserve also currently serves as AT&T's transfer agent. The
information agent may contact holders of shares of AT&T common stock by mail,
telephone, facsimile transmission and personal interviews and may request
brokers, dealers and other nominee shareholders to forward materials relating to
this exchange offer to beneficial owners. The information agent and the exchange
agent each will receive reasonable compensation for their respective services,
will be reimbursed for reasonable out-of-pocket expenses and will be indemnified
against liabilities in connection with their services.

                                       58
<PAGE>   65

     Neither the information agent nor the exchange agent has been retained to
make solicitations or recommendations. The fees they receive will not be based
on the number of shares of AT&T common stock tendered under this exchange offer;
however, the exchange agent will be compensated in part on the basis of the
number of letters of transmittal received and the number of account statements
distributed.

     AT&T has retained certain other persons to serve as local exchange agents
in connection with this exchange offer in jurisdictions outside the United
States. These local exchange agents will receive reasonable compensation and
other rights in connection with their services.

dividend on AT&T common stock to $.0375 per share. If AT&T's board of directors
declares a quarterly dividend on the AT&T common stock after commencement of
this exchange offer but prior to the expiration date, it is possible that the
record date for determining holders of AT&T common stock entitled to receive the
dividend would be a date before the expiration date. Tendering your shares of
AT&T common stock in this exchange offer will not change your status as a record
holder of AT&T common stock, except with respect to those of your shares of AT&T
common stock that are accepted for exchange upon completion of this exchange
offer. This means that if you tender shares of AT&T common stock before the
record date for a dividend, you will continue to be the record holder of those
shares of AT&T common stock on the record date and you will be entitled to
receive payment of the dividend if the record date is a date prior to the
expiration date. In such event, the quarterly dividend would be paid to you in
the normal manner and would be separate from any shares of AT&T Wireless Group
tracking stock, and cash instead of fractional shares, issued to you in this
exchange offer.

dividend with respect to any shares of AT&T common stock that are not exchanged
pursuant to this exchange offer.

                        BUSINESS OF AT&T WIRELESS GROUP

OVERVIEW

     AT&T Wireless Group is one of the largest wireless service providers in the
United States, based on $7.5 billion in revenue for the nine months ended
September 30, 2000. Including its partnership markets, AT&T Wireless Group had
nearly 15 million total subscribers as of September 30, 2000. AT&T Wireless
Group focuses on revenue growth through the retention and expansion of its
subscriber base. AT&T Wireless Group seeks to do this by providing new and
innovative services that distinguish it from its competitors. Examples include
pricing plans that simplify customer choice, such as AT&T Digital One Rate
service.

     AT&T Wireless Group operates one of the largest U.S. digital wireless
networks. AT&T Wireless Group, including its partnership and affiliate markets,
currently holds 850 megahertz and 1900 megahertz licenses to provide wireless
services covering 97% of the U.S. population, with approximately 79% of the U.S.
population covered by at least 30 megahertz of wireless spectrum as of September
30, 2000. As of September 30, 2000, AT&T Wireless Group's built network,
including partnership and affiliate markets, covered 73% of the U.S. population.
This includes operations in 48 of the 50 largest U.S. metropolitan areas. By
December 31, 2000, AT&T Wireless Group expects that its built network, including
partnership and affiliate markets, will cover over 75% of the U.S. population.
AT&T Wireless Group supplements its own operations with roaming agreements that
allow its subscribers to use other providers' wireless services in regions where
AT&T Wireless Group does not have operations. Through these roaming agreements,
AT&T Wireless Group is able to offer its customers wireless services covering
over 95% of the U.S. population. AT&T Wireless Group plans to continue to
increase its coverage and the quality of its services by expanding the footprint
and capacity of its network at an increased pace and by acquiring or partnering
with other wireless providers.

     AT&T Wireless Group historically has provided its wireless voice and data
services using primarily TDMA, analog and CDPD technologies. On November 30,
2000, AT&T Wireless Group announced plans to deploy a GSM platform to facilitate
the deployment of next generation technology. On the same day, it was announced
that AT&T and AT&T Wireless Services entered into a binding letter agreement
with DoCoMo, a Japanese wireless communications company, for DoCoMo's investment
in AT&T representing an economic interest in the AT&T Wireless Group and for the
formation of a strategic alliance with AT&T Wireless Group to develop the next
generation of mobile multimedia services for global-standard, high-speed
wireless network. The parties signed final agreements for this investment on
December 20, 2000.

     AT&T Wireless Group has focused on building out its digital network,
including upgrading its analog systems to digital in its 850 megahertz markets,
and on migrating its customers from analog to digital service.

AT&T Wireless Group believes that digitalization improves capital efficiency,
lowers network operating costs and allows it to offer higher quality services.
As of September 30, 2000, AT&T Wireless Group had upgraded 99% of its 850
megahertz markets to digital based systems and all of its 1900 megahertz markets
are digital based. As of September 30, 2000, over 87% of AT&T Wireless Group's
consolidated subscribers used digital services, accounting for over 94% of its
traffic. AT&T Wireless Group believes that these percentages are substantially
greater than the industry average, excluding AT&T Wireless Group.

     AT&T Wireless Group markets its products and services primarily under the
AT&T brand name. AT&T Wireless Group believes that AT&T's widely recognized
brand has increased consumer awareness of, and confidence in, AT&T Wireless
Group's products and services.

     On October 25, 2000, AT&T announced plans to restructure its major business
units such that each will be represented either by a tracking stock or, as in
the case of AT&T Wireless Group, an asset-based common stock. This section
describes primarily the business of AT&T Wireless Group prior to the
implementation of AT&T's restructuring plan.

AT&T WIRELESS GROUP

     AT&T Wireless Group tracking stock is currently a tracking stock of AT&T
designed to reflect the separate economic performance of AT&T Wireless Group.
Except as described below, AT&T attributes all of AT&T's current wireless
operations to AT&T Wireless Group, including:

     - all mobile and fixed wireless licenses,

     - all wireless networks, operations, cell sites, retail operations,
       wireless customer care facilities and customer location assets, and

     - interests in partnerships and affiliates providing wireless mobile
       communications in the United States and internationally.

     AT&T Common Stock Group initially retained:

     - existing and future wireless activities that stem from country-specific
       joint venture relationships that are predominantly non-wireless, and

     - incidental wireless capabilities or links in any backbone or other
       communications network that is predominantly non-wireless.

     Prior to the spin-off, we currently intend to include all future wireless
activities in AT&T Wireless Group. Our board of directors may, however, in its
discretion, but subject to the AT&T Wireless Group policy statement, direct new
businesses and assets to AT&T Wireless Group or to the rest of AT&T or dispose
of or transfer businesses or assets of either group. Following the spin-off, we
expect AT&T Wireless Services to own substantially the same assets that were
attributed to the AT&T Wireless Group immediately prior to the spin-off.

     AT&T Common Stock Group currently offers and is expected to continue to be
able to offer wireless services under sales agency or other arrangements with
AT&T Wireless Group. These transactions are described in more detail below and,
up to now, have been implemented under AT&T Wireless Group policy statement. We
expect to enter into new arrangements between AT&T and AT&T Wireless Services in
connection with the spin-off.

ARRANGEMENTS BETWEEN AT&T COMMON STOCK GROUP AND AT&T WIRELESS GROUP

     AT&T has sought to manage AT&T Common Stock Group and AT&T Wireless Group
in a manner designed to maximize the operations, unique assets and value of both
groups. Following the issuance of AT&T Wireless Group tracking stock, AT&T
Wireless Group has been able to:

     - use the powerful AT&T brand name on the same basis as any other AT&T
       business,

     - use AT&T's sales force through cross marketing arrangements and through
       bundled offers, as may be agreed by AT&T and AT&T Wireless Group, of
       wireless with the services of other AT&T businesses,

     - use AT&T's intellectual property and technology, and

     - benefit from AT&T's favorable purchasing contracts with major network and
       equipment suppliers.

     The relationship between the two groups has been governed by AT&T Wireless
Group policy statement, including the process of fair dealing described under
"Relationship Between AT&T Common Stock Group and AT&T Wireless Group Prior to
the Spin-Off -- AT&T Wireless Group Policy Statement -- General Policy."
Although our board of directors has no present intention to do so, it may
modify, suspend or rescind the policies set forth in the AT&T Wireless Group
policy statement, adopt additional policies or make exceptions to existing
policies, at any time, without the approval of our shareholders, subject to
limitations we describe under "Relationship Between AT&T Common Stock Group and
AT&T Wireless Group Prior to the Spin-Off -- AT&T Wireless Group Policy
Statement" and our board of directors' fiduciary duties.

     In the event of the spin-off, the assets and liabilities of AT&T Wireless
Group are expected to be transferred to AT&T Wireless Services, a subsidiary of
AT&T that currently holds a substantial amount of the assets of AT&T Wireless
Group. If specified conditions are satisfied, we expect AT&T Wireless Services
to be an independent company by mid-2001. The specific terms and conditions of
the spin-off of AT&T Wireless Services will be governed by a separation and
distribution agreement entered into among AT&T and AT&T Wireless Services. In
addition, we expect that AT&T and AT&T Wireless Services will enter into a
number of other agreements in connection with the spin-off, which would govern
the parties' relationship. For more information on the spin-off and the
relationship between AT&T and AT&T Wireless Services after the spin-off, please

Services Following the Spin-Off" on page 118.

INDUSTRY OVERVIEW

  General

     Wireless communications systems use a variety of radio frequencies to
transmit voice and data. Broadly defined, the wireless communications industry
includes one-way radio applications, such as paging or beeper services, and
two-way radio applications, such as cellular telephone, enhanced specialized
mobile radio services, PCS and fixed wireless services. The FCC licenses the
radio frequency used to provide each of these applications.

     Since its introduction in 1983, wireless service has grown dramatically. As
illustrated by the following chart, domestic cellular, enhanced specialized
mobile radio and PCS providers experienced average annual rates of growth of 23%
and 29% in revenues and subscribers, respectively, over the five-year period
from 1994 to 1999.

  Recent industry trends

     The growth in the wireless communications industry has been shaped by a
number of industry trends that are likely to continue in the near future.

     Expanding penetration fuels network optimization.  The U.S. wireless
industry has experienced an increase in absolute subscriber additions and
wireless penetration levels. For example, the number of ending subscribers
increased by 8.1 million in 1994 and by 16.8 million in 1999 at the same time as
penetration grew from 9.4% to 30.9%, respectively. Increased penetration allows
wireless providers to distribute the fixed costs of a wireless network over
greater numbers of users, thereby optimizing network usage. Wireless penetration
in other developed nations, particularly in Western Europe and Japan, is
currently substantially higher than in the United States. The experience of
wireless providers in these developed nations has shown that the market for
wireless services has an inflection point with regard to subscriber penetration
whereby the number of subscribers and penetration accelerates as wireless
service usage becomes more ubiquitous. In addition, those same international
wireless providers have experienced growth in earnings before interest, taxes,
depreciation and amortization, or EBITDA, at a greater rate than subscriber
growth as network usage increases. AT&T Wireless Group believes that the U.S.
wireless industry is approaching a similar inflection point in subscriber
penetration and is likely to develop along the same path as international
wireless industries have developed.

     Rate simplification eases customer choice and drives consolidation.  AT&T
Wireless Group has led the industry in simplifying customer choice through
pricing plans. In May 1998, AT&T Wireless Group revolutionized the industry by
offering AT&T Digital One Rate service, which, for the first time, charged one
rate with no separate roaming or long distance fees for domestic calls across
the United States. In addition, AT&T Wireless Group has introduced a simplified
national prepaid wireless service that provides wireless communications to
customers with no long-term contract, credit check, deposit or bill. AT&T
Digital One Rate, prepaid wireless, and similar plans by other service providers
have increased wireless penetration in the United States. AT&T Wireless Group
believes that the introduction of other simplified, targeted rate plans,
including prepaid products, will continue to increase wireless penetration. In
addition, because roaming costs to the wireless provider can exceed the amount
charged to the subscriber under these single rate plans, wireless providers have
been attempting to establish national coverage through acquisitions, thus
driving consolidation.

     Declining costs of service results in mass market availability.  As the
cost of wireless service has declined, it has become, in an extremely short
period of time, a mass market product rather than a luxury good. AT&T Wireless
Group expects that competition in each wireless market will continue to lead to
further price declines, which should make wireless service available to an even
greater number of potential users. Experience indicates that this widespread
usage will in turn cause even more people to use wireless services, especially
as the price of wireless service declines relative to the price of wireline
service. AT&T Wireless Group believes that these developments are likely to
drive continued growth in the wireless communications industry.

                                       67
<PAGE>   74

     Digital service increases utility and functionality of wireless
services.  Technological advancements, from longer battery life to improved
voice quality, have begun to make wireless service increasingly comparable to
wireline communications. Additionally, customers have begun to expect custom
calling features that are similar to those available on a wireline network.
Digital service, as opposed to analog service, permits wireless providers to
offer these types of enhanced services to users. Wireless providers will need to
continue to invest in network upgrades to offer advanced services in order to
attract and retain subscribers.

     Wireless data applications will drive expanded wireless usage.  Existing
and new wireless data technologies, coupled with the widespread use of the
Internet, have caused wireless providers to focus on wireless data services
offerings. Historically, these services predominantly have been used to date to
carry corporate data applications. AT&T Wireless Group has been a leader in this
emerging market. Data network coverage is now available using its CDPD packet
data network in over 60% of AT&T Wireless Group's voice network footprint, which
AT&T Wireless Group believes provides a critical advantage in the cost-effective
provision of wireless data services. In addition to CDPD technology, AT&T
Wireless Group has announced plans to deploy GPRS and third generation
technologies capable of greater data speeds.

     The introduction of new applications for corporate and consumer users, such
as mobile originated short message services, access to email, news, sports,
weather summaries, travel services, financial information and services and
comparison shopping applications, will drive the growth for wireless data
network services. To this end, enabling technologies, such as wireless access
protocol, or WAP, provide an environment that encourages developers to create
innovative data services for wireless networks. In addition, applications, such
as email, instant messages, banking, wireless portals and web services, are
being developed and marketed. AT&T Wireless Group believes that the development
and deployment of so called "third generation" wireless networks will drive
further growth in wireless data services and applications due to increased
capacity, speed and lower costs.

BACKGROUND

     AT&T Wireless Group has licenses to use four portions of the radio spectrum
that the FCC has made available for the transmission of voice and data signals:
850 megahertz, 1900 megahertz, 2.3 gigahertz and 38 gigahertz.

     AT&T Wireless Group provides its mobile voice services using both 850
megahertz cellular and 1900 megahertz PCS licenses. AT&T Wireless Group does not
manage its business for these spectrums separately. Rather, AT&T Wireless Group
manages its business to provide network coverage irrespective of the spectrum.
From a marketing and operational perspective, AT&T Wireless Group defines and
manages its markets geographically, usually around an urban area or other
geographic region. These geographic markets may use either 850 megahertz or 1900
megahertz spectrum or both. Geographic markets that use predominantly 850
megahertz spectrum have been in operation longer and therefore are more mature
than those markets that exclusively use 1900 megahertz spectrum.

     The 850 megahertz wireless markets originally used analog based systems,
although digital technology has been introduced in most markets. As of September
30, 2000, AT&T Wireless Group had upgraded 99% of its 850 megahertz markets to
digital based systems. The 1900 megahertz markets all are digital based.

                                       68
<PAGE>   75

     AT&T Wireless Group, including its partnership and affiliate markets,
currently holds 850 megahertz and 1900 megahertz licenses to provide wireless
services covering 97% of the U.S. population. As shown in the table below, as of
September 30, 2000, approximately 79% of the U.S. population were covered by at
least 30 megahertz of wireless spectrum:

     Analog systems currently have several limitations, including comparative
lack of privacy and limited capacity. However, analog handsets are compatible
with all analog systems in all markets within the United States.

     Second generation digital systems in the U.S., whether in the 850 megahertz
or 1900 megahertz spectrum, convert voice or data signals into a stream of
digits that is compressed before transmission, enabling a single radio channel
to carry multiple simultaneous signal transmissions. AT&T Wireless Group
believes that digital technology offers many advantages over analog technology,
including substantially increased network capacity, greater call privacy,
enhanced services and features, lower operating costs, reduced susceptibility to
fraud and the opportunity to provide improved data transmissions.

     Second generation digital systems use one of three principal signal
transmission technologies, or standards, none of which is compatible with the
others:

     - TDMA, or time division multiple access,

     - CDMA, or code division multiple access, or

     - GSM, or global system for mobile communications.

     AT&T Wireless Group believes that three of the five recognized advanced
digital signal transmission technologies, or standards, which are in various
stages of development, have more commercial momentum than the remaining two.
These three are:

     - EDGE, or enhanced data for global evolution,

     - CDMA 2000, and

     - UMTS, or universal mobile telecommunications systems.

These so-called "third generation" or "3G" technologies will allow high-speed
wireless packet data services and ultimately voice services using Internet
Protocol. Widespread deployment of 3G technology is expected to occur in the
industry beginning in 2002. A fourth technology, GPRS, or general packet radio
service, is generally considered to be an interim step between current and 3G
technologies. GPRS standards have been developed by recognized standards-setting
bodies, and there has been some commercial deployment by carriers outside the
U.S. and some U.S. carriers have announced plans to deploy GPRS. EDGE standards
also are complete but equipment is still under development and AT&T Wireless
Group is not aware of any commercial deployment. UMTS standards address more
complex data applications and are not yet complete, but equipment development
has begun. UMTS is expected to be initially available in Japan in 2001, in
Europe in 2002 and subsequently in North America. UMTS is also known as WCDMA.
Some carriers have selected CDMA 2000 as their path to wideband data
applications, as an alternative to the GPRS/EDGE/UMTS path selected by AT&T
Wireless Group. Despite the similarity of the acronyms, CDMA 2000 and WCDMA are
not compatible.

                                       69
<PAGE>   76

     AT&T Wireless Group selected TDMA as its second generation digital wireless
standard, although it does operate a small number of CDMA markets that were
operating that technology when AT&T Wireless Group acquired them. AT&T Wireless
Group offers its subscribers tri-mode handsets that permit the user to access
both its analog and digital TDMA systems, whether operating in 850 megahertz or
1900 megahertz spectrum. AT&T Wireless Group also has plans to deploy third
generation technologies to enhance both voice and data services.

     AT&T Wireless Group also has licenses to provide communications services
utilizing 38 gigahertz digital spectrum in 156 geographic areas covering a total
population of approximately 220 million and including more than 80 of the
largest 100 metropolitan markets. These licenses were acquired in large part
through AT&T's acquisition of Teleport Communications Group Inc.

     AT&T Wireless Group has also acquired licenses for radio spectrum in the
2.3 gigahertz range. AT&T Wireless Group expects to use this spectrum for its
fixed wireless operations.

STRATEGY

     AT&T Wireless Group's goal is to be the premier provider of high-quality
wireless communication services, whether mobile or fixed, voice or data, to
businesses or consumers, in the United States and internationally. AT&T Wireless
Group believes that the following are key elements to enable it to meet its
goal:

     - continue the expansion of its digital network to add capacity, improve
       quality and provide consistent features regardless of location,

     - continue to lower its operating costs and improve capital efficiency by
       expanding its digital, mobile wireless network and increasing the use of
       more efficient channels of distribution,

     - deploy a GSM platform as the basis for implementation of third generation
       services, including GPRS, EDGE and, ultimately, UMTS,

     - target distinct consumer and business customer segments with wireless
       offers that match their needs for voice and data services in order to
       increase its subscriber base and revenue,

     - use the benefits of AT&T Wireless Group's relationship with and use of
       the resources of AT&T, including the use of AT&T brand and, when
       appropriate, AT&T's distribution channels and cross marketing
       opportunities, and

     - take advantage of its existing wireless spectrum, digital network,
       customer base and the AT&T brand with new growth initiatives, including
       wireless data and fixed wireless opportunities.

  Continue the expansion of its digital network

     AT&T Wireless Group believes it is competitively critical to expand and
improve its network coverage footprint, as well as to increase capacity in
existing TDMA markets, in order to provide coverage throughout the nation, and
offer consistent features regardless of location. AT&T Wireless Group regularly
monitors quality and identifies specific areas in existing markets where calls
may be dropped or transmission quality is sub-optimal. As a result, AT&T
Wireless Group has taken a number of steps to increase its network coverage,
including the purchase of 1900 megahertz PCS licenses, to accelerate digital
build outs in 850 megahertz and 1900 megahertz markets, to increase the capacity
of its TDMA network, and to acquire or partner with other wireless providers.
AT&T Wireless Group, including its partnership and affiliate markets, currently
has licenses covering 97% of the U.S. population, with approximately 79% of the
U.S. population covered by at least 30 megahertz of wireless spectrum as of
September 30, 2000. In addition, in many of its markets, AT&T Wireless Group
possesses licenses for both 850 megahertz and 1900 megahertz spectrum. In each
market in which AT&T Wireless Group is not currently operating, AT&T Wireless
Group evaluates the benefits and costs of building out its license versus
acquiring or partnering with other experienced wireless providers before it
decides on the appropriate method of expanding into that market. The timing of
these decisions depends upon a variety of factors, including the size of the
prospective market, the location of the market relative to other AT&T Wireless
Group markets, the economics of existing roaming agreements and anticipated
industry developments.

     Digital build out.  AT&T Wireless Group has aggressively pursued the build
out of its digital network. In the years ended December 31, 1997, 1998 and 1999,
capital expenditures for build out of owned and operated 1900 megahertz licenses
and to increase capacity, improve quality and upgrade to digital in 850
megahertz markets totaled $1,514 million, $1,029 million and $2,333 million,
respectively. As of September 30, 2000, AT&T Wireless Group had upgraded 99% of
its 850 megahertz markets to digital based systems. As of September 30, 2000,
TDMA or other digital systems covering 61% of AT&T Wireless Group's 155 million
1900 megahertz licensed POPs, including affiliates, were in service in those
markets.

     Acquisitions.  AT&T Wireless Group has and will expand its digital mobile
wireless network through acquisitions when it is economic to do so. For example,
on May 3, 1999, AT&T Wireless Group acquired Vanguard Cellular Systems, Inc., an
independent operator of wireless telephone systems in the United States with
approximately 6.9 million potential customers and over 700 thousand subscribers
as of the date of acquisition. Vanguard served 26 markets in the Eastern United
States, including the Mid-Atlantic and Ohio Valley Super Systems and the New
England metro-clusters. In addition, in August 1999, AT&T Wireless Group
acquired Honolulu Cellular Telephone Company, a provider of cellular services
covering Oahu, Hawaii with approximately 900 thousand potential customers and
over 125 thousand subscribers as of the date of its acquisition.

     In February 2000, AT&T and Dobson Communications Corporation, through a
joint venture, acquired American Cellular Corporation. AT&T contributed its
interest in the joint venture to AT&T Wireless Group as of the date of the
acquisition. This acquisition increased AT&T Wireless Group's coverage in New
York State and several mid-west markets by adding approximately 450 thousand
subscribers as of the acquisition date. Further, in June 2000, AT&T Wireless
Group purchased the assets of Wireless One Network, L.P., including wireless
systems in northwest and southwest Florida covering a population base of 1.6
million potential customers and serving approximately 190 thousand subscribers
as of the acquisition date.

     In June 2000, AT&T Wireless Group announced that it had agreed to acquire
wireless systems in Houston and San Diego, as well as the remaining 50% interest
that it did not own in CMT Partners, which operates a wireless system in the San
Francisco Bay Area. The AT&T Wireless Group closed the CMT Partners transaction
on June 29, 2000. CMT Partners covers a population base exceeding 7 million
potential customers and, as of June 30, 2000, served nearly 1 million
subscribers. On September 29, 2000, AT&T Wireless Group closed the acquisition
of the San Diego Wireless System, which covers a population base of 3 million
potential customers. Also, during the third quarter of 2000, AT&T Wireless Group
acquired a wireless system on the big island of Hawaii. Combined, the San Diego
and Hawaii markets served more than 180 thousand subscribers as of September 30,
2000. AT&T Wireless Group expects to close the acquisition of the Houston
wireless system during December 2000.

     On October 2, 2000, AT&T Wireless Group acquired a wireless system in
Indianapolis, Indiana, which covers a population base of approximately 3 million
potential customers, and served approximately 100 thousand subscribers as of the
acquisition date.

     On November 13, 2000, AT&T Wireless Group acquired wireless systems in
several New England Markets. These New England wireless systems acquired cover a
population base of nearly 2 million potential customers and served approximately
38 thousand subscribers as of the acquisition date.

     Establish partnerships and affiliates.  AT&T Wireless Group also will
continue to establish local market partnerships and affiliates with other
wireless operators in order to accelerate the build out of its digital mobile
wireless network. In addition to existing partnership arrangements for its 850
megahertz markets, AT&T Wireless Group has entered into a number of joint
ventures and affiliations to expand its 1900 megahertz digital coverage. Key
partnerships and affiliates include the following:

  * As of September 30, 2000.

 ** In November 1998, AT&T Wireless Group and BellSouth combined their jointly
    owned cellular properties in Los Angeles, Houston and Galveston, plus cash,
    to form AB Cellular Holding, LLC, which owns, controls and supervises all
    three properties. AT&T Wireless Group anticipates that, in the fourth
    quarter of 2000, the AT&T Wireless Group will relinquish all of its 55.6%
    equity interest in this joint venture in exchange for all of the net assets
    of the Los Angeles property currently held by AB Cellular.

*** In November 2000, TeleCorp PCS, Inc. announced completion of its acquisition
    of Tritel, Inc. As a result of completion of the transaction, AT&T Wireless
    Group owns approximately 23% of the combined entity.

  Continue to lower its operating costs and improve capital efficiency by
  expanding its digital mobile wireless network and increasing the use of more
  efficient channels of distribution

     AT&T Wireless Group believes that its success also will depend in large
part on its ability to continue to lower its operating costs in order to have
the flexibility to offer various pricing plans and to be cost competitive. AT&T
Wireless Group already has taken a number of steps to lower its operating costs
associated with providing network service, and is taking a number of initiatives
to lower its marketing and sales costs.

     Lower unit network costs and capital requirements.  As described above,
AT&T Wireless Group is expanding its footprint across the United States. AT&T
Wireless Group pays other wireless providers negotiated roaming rates when AT&T
Wireless Group customers make or receive wireless calls when located in other
approved wireless providers' coverage areas. Because roaming costs to the
wireless provider can be significant or exceed the amount charged to the
subscriber, it is extremely advantageous to be able to provide services on AT&T
Wireless Group's network. As it builds out its network to achieve these roaming
savings, AT&T Wireless Group purchases equipment from multiple vendors and
aggressively negotiates with each vendor for volume discounts, in order to
reduce cost.

     In the interim, AT&T Wireless Group has been able to reduce roaming charges
significantly. The AT&T Wireless Group has been able to negotiate favorable
roaming rates with most wireless providers across the United States based upon
volume and growth. In addition, the AT&T Wireless Group's proprietary
Intelligent Roaming Data Base, or IRDB, directs wireless subscribers to
preferred service providers whenever they travel outside their wireless
home-coverage area. The IRDB maintains a list of wireless carriers and their
frequency bands, ranked by priority. This is designed to provide service in more
areas at favorable roaming rates. The updated IRDB is downloaded over the air
into each digital multi-network phone periodically. During the IRDB process, the
wireless phone scans all bands to determine which service providers are
available. The phone registers, or "locks on," immediately if it finds
sufficiently strong AT&T Wireless Group service, the top priority. If AT&T
Wireless Group does not offer service in the area, the IRDB instructs the phone
to search for an affiliate or a partner service provider. When an affiliate or a
partner is not available, the phone scans for a "favored" service provider, one
that is preferred over a carrier not categorized in the IRDB.

     Lower marketing and sales expense.  AT&T Wireless Group has begun a number
of initiatives designed to lower its customer acquisition cost, as well as its
customer care expenses. For example, AT&T Wireless Group has been actively
seeking lower cost distribution channels for its products and services. AT&T
Wireless Group is increasing the number of its company-owned stores, which are
one of the lowest cost channels for distributing and signing up customers. As of
September 30, 2000, there were approximately 460 company-owned stores throughout
the United States. In addition, in June 1999, AT&T Wireless Group began using
the Internet as a vehicle for customer acquisition, as well as for customer
care. In addition to allowing customers to sign up for wireless services over
the Internet, resulting in a lower cost to add a new subscriber to AT&T Wireless
Group than other channels, subscribers can access their account and obtain
answers to routine inquiries that would otherwise require a customer care
representative. Since its introduction, the number of visits to the AT&T
Wireless Group's Internet site has grown to approximately 2.7 million per month
as of October 2000.

  Deploy a GSM Platform to Implement Third Generation Services

     Third generation technologies will allow high-speed wireless packet data
services and ultimately voice services using Internet Protocol. In order to be
successful, any third generation strategy must allow the wireless provider to
achieve a pervasive footprint quickly and cost effectively. In addition, third
generation networks that achieve global economies of scale and allow for global
roaming will have a significant advantage.

     Starting in the second half of 2001, AT&T Wireless Group plans to deploy a
GSM platform for GPRS, EDGE, and subsequently UMTS data services, as well as
associated voice services. This platform, which will be deployed as an overlay
on AT&T Wireless Group's second generation voice network, will provide a cost-
effective means for AT&T Wireless Group to offer customers of a wide range of
data service offerings earlier than previously planned. Much of the GSM and GPRS
equipment for this overlay network is technologically mature and readily
available in the market today from a highly competitive source of supply. In the
longer
                                       73
<PAGE>   80

term, this platform is expected to provide multi-media services using the
anticipated global standard of UMTS.

     AT&T Wireless Group plans to sell phones combining TDMA and GSM/GPRS/EDGE
technology, which would provide customers the benefit of access to AT&T Wireless
Group's current voice network as well as the new high-speed data services. AT&T
Wireless Group is in discussions with manufacturers to develop phones compatible
with such services, based on industry specifications. When these new data
services become available, AT&T Wireless Group will be able to sell GSM/GPRS and
EDGE devices in a variety of forms (e.g., phones, PDAs, laptops), to address a
broad range of customer needs. The eventual deployment of UMTS in AT&T Wireless
Group's network is expected to enable the transmission of multimedia services
(e.g., streaming audio and video) to customer devices.

     AT&T Wireless Group plans to make GPRS available starting in 2001, and EDGE
is expected to be available in 2002. AT&T Wireless Group currently plans to
deploy UMTS technology beginning in 2003, depending on the availability of
network equipment and customer devices.

     Due to its broad international acceptance, the GSM platform equipment
needed is readily available in the market. The overlay strategy also will allow
AT&T Wireless Group to utilize its existing cell site facilities and spectrum.
Because of these efficiencies, the AT&T Wireless Group expects that its network
capital expenditures over the period of deployment associated with the high
speed data technology in its third generation plans will be only modestly
greater than its earlier third generation migration plan, but may occur in
earlier periods.

     The customer benefits of this strategy include earlier availability of a
broad array of high-speed data services and devices, and enhanced international
roaming capability. Overall, this strategy provides AT&T Wireless Group an
opportunity for more rapid and greater penetration of the wireless data market
than previously planned.

 Target distinct consumer and business customer segments with wireless offers
 that match their needs for voice and data services in order to increase its
 subscriber base and revenue

     AT&T Wireless Group believes that one key to success in the wireless
industry is the ability to target customer segments and provide offers that
match the needs of those segments. Certain segments respond to pricing plans
tailored to their usage patterns while other segments are more attuned to
customized service features. AT&T Wireless Group has been a leader in
differentiating its services through its use of targeted offerings and its
introduction of new features and services.

     AT&T Digital One Rate service.  In May 1998, AT&T Wireless Group introduced
its AT&T Digital One Rate service, which targets high value customers (i.e.,
customers that spend over $60 per month on wireless services) who travel
frequently and make frequent long distance calls. In August 2000, AT&T Wireless
Group introduced six new AT&T Digital One Rate calling plans, giving customers
more minutes for the same monthly charge. The introduction of AT&T Digital One
Rate service redefined the industry by charging one rate with no roaming or long
distance fees for domestic calls across the United States.

     AT&T Regional Advantage and AT&T Digital Advantage services.  AT&T Wireless
Group has created other service plans because it believes there are other
opportunities to segment the market with simplified pricing plans. AT&T Regional
Advantage is designed for mobile individuals who travel across a multi-state,
regional calling area. When traveling in the regional area customers pay no
roaming or domestic long distance charges. This program addresses customers that
frequently travel to neighboring states, but do not travel across the nation.
AT&T Wireless Group also offers AT&T Digital Advantage for customers that spend
most of their time within a local area. AT&T Digital Advantage offers these
customers a large number of local minutes to use in their home calling area.

     AT&T group plans.  AT&T has developed offers for groups that are in
frequent contact with a predetermined number of other wireless subscribers. For
consumers, AT&T Wireless Group developed the AT&T Family Plan. With the AT&T
Family Plan, each family member has his or her own wireless number that allows
for unlimited calls between wireless numbers on the account within the defined
family calling area.
                                       74
<PAGE>   81

The family's charges are then provided on a single wireless bill. For
businesses, AT&T Wireless Group offers AT&T Group Calling, the wireless
industry's first business offer with unlimited calling among a wireless group of
five to 200 subscribers and to as many as five wireline numbers within a
designated group calling area. AT&T Group Calling is designed for local, mobile
businesses, such as sales and service, delivery and distribution, dispatch and
contractors, that operate within a specific geographic area.

     Wireless Office Service.  Wireless Office Service integrates wireless
phones into a company's office, campus or plant telephone network. Calls to and
from the wireless phone can be routed through a company's network as if the
calls were being made from or received on a desk phone. Users can receive calls
dialed to their desk phone on their wireless phone when the user is within the
expanded AT&T Wireless Group's network. Wireless Office Service provides one
number call delivery, four-digit dialing, enhanced radio frequency coverage and
low flat-rate billing for airtime usage within a customer's office, campus or
plant.

     AT&T Corporate Digital Advantage program.  The AT&T Corporate Digital
Advantage program was created for large and middle sized businesses. This
program combines simplified wireless purchasing and management with nationally
consistent service, airtime, and equipment pricing in all AT&T Wireless Group
markets.

     Prepaid Wireless Services.  AT&T Wireless Group recently launched a new and
improved prepaid wireless program. AT&T Wireless Group markets the prepaid
program under two product names, depending upon the target segment. Free2Go
Wireless from AT&T Wireless Group targets the youth market, while AT&T Prepaid
Advantage targets the mass market. Both offer digital prepaid wireless service
as a pay-in-advance wireless product that provides wireless communications to
customers with no annual contract, no credit check, no deposit and no monthly
bill. In addition, both offer customers the choice of a Local or National
Calling Plan, the ability to use any compatible digital multi-network phone,
access to enhanced digital PCS features, and both plans include domestic long
distance for all calls placed in the United States. AT&T Wireless Group prepaid
wireless service is designed to meet the needs of customers that want to manage
their expenses, prefer to pay in cash, lack credit or have difficulty obtaining
credit.

     Enhanced features.  AT&T Wireless Group has been an industry leader in the
migration of subscribers from analog to digital service. At the present time,
over 94% of AT&T Wireless Group's traffic is digital, which AT&T Wireless Group
believes is substantially greater than the industry average, excluding AT&T
Wireless Group. The ability to migrate customers to digital service has
permitted AT&T Wireless Group to further differentiate its wireless offerings
through enhanced features. During October 2000, AT&T Wireless Group announced
the launch of AT&T Text Messaging service, otherwise known as two-way SMS. AT&T
Text Messaging service allows subscribers to send and receive short text
messages from their compatible phones. AT&T Wireless Group offers custom calling
services, such as voice mail, call forwarding, call waiting and three-way
calling to all of its customers. The digital network allows AT&T Wireless Group
to offer enhanced features to its customers, including extended battery life,
message waiting indicator, text messaging and caller ID. It also offers a
variety of other enhanced features, including enhanced directory assistance,
which enables callers to be connected to the party whose number is sought
without hanging up and redialing.

  Use the benefits of AT&T Wireless Group's relationship with AT&T

     AT&T Wireless Group believes that its relationship with AT&T has provided
it with significant competitive advantages. As part of the spin-off, AT&T and
AT&T Wireless Group expect to enter into certain contracts and other
arrangements which after the spin-off will be intended to continue many of the
advantages enjoyed by AT&T Wireless Group before the spin-off. For more
information, please see "The Spin-Off" on page 113 and "Relationship between
AT&T and AT&T Wireless Services following the "Spin-Off" on page 118. These
continued advantages may include:

     - use of the powerful AT&T brand name substantially in the same manner as
       has been used by AT&T Wireless Group up to now,

                                       75
<PAGE>   82

     - an opportunity to use AT&T sales force through cross marketing
       arrangements and, where appropriate, through bundled offers, as may be
       agreed by AT&T and AT&T Wireless Group, of wireless with services of
       other AT&T businesses,

     - use of specified AT&T intellectual property and technology on license
       terms as of the time of the spin-off,

     - use of the AT&T network on contractual terms, and

     - potential benefits from certain of AT&T's purchasing contracts with
       suppliers where already permitted by existing contracts or where
       arrangements can be made with such suppliers.

     AT&T brand.  The AT&T brand is one of the best known and respected brand
names in the United States. AT&T Wireless Group believes that the AT&T brand
positively impacts consumer awareness of, and confidence in, AT&T Wireless
Group's products and services. In addition, as competition in the wireless
communications industry intensifies, AT&T Wireless Group believes that the power
of a strong national brand plays an increasingly important role in consumers'
purchasing decisions.

     Marketing.  AT&T Wireless Group believes that its relationship with AT&T
Common Stock Group has and can continue to provide substantial marketing
advantages. AT&T Wireless Group will be able to enter into cross marketing
relationships with the AT&T sales force whereby AT&T's customers can be
solicited for wireless services. In addition, both AT&T Common Stock Group and
AT&T Wireless Group will have the opportunity to cooperate in bundled offers of
services designed for targeted markets.

     Technology.  AT&T Wireless Group will continue to have the advantage of
being able to use not only its intellectual property and technology but also,
under license terms as of the time of the spin-off, specified AT&T's proprietary
intellectual property and technology as well as specified intellectual property
that AT&T has the right to use through licensing or other arrangements.

     Purchasing power.  AT&T is one of the largest communications carriers in
the world, and, as such, has substantial leverage in the industry with major
equipment and other suppliers. AT&T's ability to purchase large amounts of goods
has enabled it to obtain favorable pricing and other terms with those suppliers.
Through contractual and other arrangements, AT&T Wireless Group may be able to
participate in certain of AT&T's supplier arrangements either directly or in
making its own purchasing arrangements where those arrangements allow for this
and the vendors agree to this. In addition, AT&T Wireless Group has already
developed its own relationships with many of these vendors and believes that it
will be able to effectively negotiate independent agreements where necessary or
appropriate.

 Take advantage of wireless spectrum, digital networks, customer base and brand
 with new growth initiatives, including wireless data and fixed wireless
 opportunities

     AT&T Wireless Group has been an industry leader in developing new growth
initiatives that take advantage of its existing wireless spectrum, digital
networks, customer base and brand. Working with AT&T Labs and outside vendors,
AT&T Wireless Group has targeted two growth areas for near-term expansion:
wireless data and fixed wireless.

  Wireless Data

     AT&T Wireless Group has been an industry leader in wireless data services
since it introduced the first packet-switched data network in March 1995, using
CDPD technology. AT&T Wireless Group's CDPD network currently covers 104 million
POPs. AT&T Wireless Group's CDPD customers can also roam on the CDPD networks of
other wireless providers. CDPD is an industry standard using Internet Protocol,
which allows most applications written for the Internet as well as many
corporate applications to run efficiently over the network without modification.
Relative to data services carried over circuit-switched analog or digital
wireless networks, AT&T Wireless Group's packet-switched CDPD service is a
significantly more cost effective means of sending data for the majority of
applications because it allows a channel to be shared by many users. AT&T
Wireless Group believes that its early introduction of packetized wireless data
services

                                       76
<PAGE>   83

provided it with a first mover advantage that significantly contributed to its
current leadership position. AT&T Wireless Group also believes that its
successful deployment and operation of a wireless data network, and its
competitive position in that market, will provide it significant advantages in
the deployment of GPRS, third generation networks and advanced data applications
and services.

     The development of compelling data applications will be critical to the
growth in usage of wireless data network services. AT&T Wireless Group is
developing such applications as well as supporting applications developed by
third parties. AT&T Wireless Group expends considerable effort to sign up
corporate customers to carry its applications because these customers exhibit
lower churn and often provide relatively high revenue per subscriber. Examples
of these applications include those for public safety, dispatch, wireless credit
card validation and automated vehicle location. In addition, AT&T Wireless Group
has launched its consumer data service known as "AT&T Digital PocketNet(SM)"
service. This service provides customers with access to the wireless Internet,
including wireless web sites providing content, shopping services and other
Internet-based services such as email and personal calendars. Because of the
efficiencies in using its packet-based data network, AT&T Wireless Group has
been able to offer this service at flat rates to customers who also subscribe to
a certain wireless voice calling plan.

     New devices are now driving the development of applications targeted more
broadly to consumers. These include applications involving hand held devices,
like the Palm Vx units, as well as those involving phones and laptop computers.
Applications that are currently available allow users to access their personal
information, including contact lists and calendars, as well as email, Internet
content and two-way messaging services. Additionally, AT&T Wireless Group has
introduced new applications including e-commerce and shopping services. By
providing or facilitating these applications, AT&T Wireless Group believes it
can generate new revenue streams and develop personalized relationships with its
customers.

     AT&T Wireless Group expects that the development and introduction of third
generation networks will drive wireless data usage growth by offering greater
bandwidth and network coverage at lower costs. For its third generation
strategy, AT&T Wireless Group has decided to deploy a GSM platform that will
facilitate the implementation of GPRS, EDGE and, subsequently, UMTS data
services. This entails installing an overlay of new equipment in existing and
new base stations as the GSM platform and GPRS, EDGE and UMTS capabilities are
successively introduced. AT&T Wireless Group expects to first make GPRS service
available in 2001 and EDGE service available in 2002. AT&T Wireless Group
expects to make UMTS service available in 2003, assuming availability of network
equipment and customer devices.

     In the fourth quarter of 2000, AT&T Wireless Services and AT&T entered into
a binding letter agreement with DoCoMo, a Japanese wireless communications
company, for DoCoMo's investment in AT&T representing an economic interest in
AT&T Wireless Group and for the formation of a strategic alliance. The parties
signed final agreements for this investment on December 20, 2000. For more
information, please see "Recent Developments -- DoCoMo Strategic Investment" on
page 40. AT&T Wireless Group and DoCoMo will form a strategic alliance to
develop the next generation of mobile multimedia services on a global-standard,
high-speed wireless network. AT&T Wireless Group will create a new, wholly owned
subsidiary to develop multimedia applications for its current network and a new,
high-speed wireless network built to global standards for third generation
services, such as graphic presentation of data, video e-mail, high quality music
downloads and streaming audio and video. Both AT&T Wireless Services and DoCoMo
will share technical resources and support staffing of the new subsidiary. In
addition, AT&T Wireless Group will be able to license from DoCoMo, without
additional payment, rights to DoCoMo's "i-mode" technology and related
technology as long as the relationship is in effect and for 18 months
thereafter. AT&T Wireless Group and DoCoMo will also become partners in the U.S.
and Japan for handling the roaming traffic in each other's network. Subject to
some exceptions, DoCoMo has agreed that in the U.S., Mexico or Canada, other
than through AT&T Wireless Services, it will not undertake certain activities
itself or form certain relationships with third parties. AT&T Wireless Group has
made the same agreements with respect to DoCoMo in Japan.

  Fixed Wireless

     AT&T Wireless Group believes there is a significant business opportunity to
use wireless technology to provide residential and small business customers with
high speed broadband access coupled with wireline quality voice access. Fixed
wireless service provides customers with a high-speed packet data channel that
can
                                       77
<PAGE>   84

be used by up to five data devices simultaneously (for example, five personal
computers simultaneously accessing the Internet) at download speeds of up to 512
kilobits per second. The service is expected to be capable of speeds of up to
one megabit per second by fourth quarter 2000. In addition, the offering
provides up to four lines of wireline quality voice telephony, including custom
calling features currently available over wireline networks (e.g., call waiting,
caller ID, three-way calling). AT&T Wireless Group believes that it enjoys a
time-to-market advantage with this fixed wireless solution. The technology is
currently serving customers in Dallas/Fort Worth, Texas and in San Diego,
California.

     In addition to serving more than 6,100 customers as of September 30, 2000
in the Dallas/Fort Worth and San Diego markets, AT&T Wireless Group expects to
launch service in Los Angeles, Houston, and Anchorage by the end of 2000, with
marketing beginning in these areas in 2001. AT&T Wireless Group initially has
focused its deployment of fixed wireless in markets not covered by AT&T's or its
affiliates' broadband properties.

BUSINESS OF AT&T WIRELESS GROUP

     AT&T Wireless Group offers wireless mobile and fixed voice and data
communications service to consumers and businesses in the United States,
provides air-to-ground wireless services and has interests in wireless providers
in the United States and internationally. AT&T Wireless Group's wireless voice
services are capable of operating in virtually all of the United States over its
own network or its partners' networks or through roaming agreements.

  Services and products

     Basic Services

     AT&T Wireless Group offers a variety of services for both voice and data
communications. Service can include wireless voice transmission as well as
custom calling services for digital services, such as extended battery life,
message waiting indicator, text messaging and caller ID. AT&T Wireless Group
also offers a variety of other enhanced features, including enhanced directory
assistance, which enables callers to be connected to the party whose number was
sought without hanging up and redialing.

     Specialized Wireless Offers and Services

     AT&T Wireless Group has developed a number of specialized wireless offers
and services to target distinct customer segments:

     - AT&T Digital One Rate(SM)

     - AT&T Regional Advantage and AT&T Digital Advantage services

     - AT&T group plans

     - Wireless Office Service

     - AT&T Corporate Digital Advantage program

     - Prepaid Wireless Services

     - AT&T WorldConnect(R) service

     The AT&T WorldConnect(R) service program allows AT&T Wireless Group's
customers to make and receive wireless calls for a flat roaming rate plus long
distance charges in over 100 countries across Europe, Australia, Asia, Latin
America, Africa and the Middle East, all while using their existing wireless
phone number. AT&T WorldConnect(R) service enables customers to enjoy the
convenience of wireless service at rates less than those charged by many
international hotels. A customer using a GSM wireless phone with AT&T
WorldConnect(R) service and a laptop computer with a GSM compatible modem card
is able to send and receive email and originate faxes, check a calendar, browse
the Internet and carry out other online transactions. AT&T WorldConnect(R)
service also provides discounted international calling from AT&T Wireless Group
markets in the U.S. and roaming with its U.S. Digital multi-network phone in
select countries. For simplicity, international and domestic wireless charges
are both included on the customer's regular monthly AT&T Wireless bill. We
describe each of the other specialized wireless offers and services under
"-- Strategy."

     Data Services

     CDPD network service.  As a packet-switched network, AT&T Wireless Group's
CDPD network takes advantage of the fact that with many data applications, data
is sent in bursts with intermittent quiet periods, which allows many users to
share the network channel. As a result, relative to data services carried over
circuit-switched analog or digital wireless networks, AT&T Wireless Group's
packet-switched CDPD service is a significantly more cost-effective means of
sending data for the majority of applications because it allows a channel to be
shared by many users. For example, for many applications, AT&T Wireless Group's
packet-switched CDPD network allows it to offer its customers unlimited usage,
most often for a flat monthly fee. This makes its CDPD network service
attractive for a variety of new applications. AT&T Wireless Group has created
applications and offers using the CDPD network for businesses, public agencies
and consumers.

     To date, corporations and public agencies have been significant users of
AT&T Wireless Group's CDPD service. These customers typically use AT&T Wireless
Group's CDPD service to carry industry-specific applications. Examples of such
applications include public safety applications, dispatch applications, wireless
credit card validation and automated vehicle location services.

     New devices are driving the development of broader applications targeted to
consumers. Users may access these applications with hand held devices, like the
Palm Vx, as well as phones and laptop computers.

     Applications on hand held devices.  For hand held devices, AT&T Wireless
Group now has access to new CDPD modems that work with the Palm Vx device. Users
can access Internet-based information from devices equipped with these modems. A
leading example of this is the OmniSky service available for the Palm Vx. With a
Palm Vx equipped with a modem that connects to AT&T Wireless Group's CDPD
network, an OmniSky subscriber can access email as well as several hundred
content providers that have created information specifically for hand held
devices.

     Applications on phones.  AT&T Wireless Group has been instrumental in the
formation of a worldwide standard called the Wireless Application Protocol. This
standard allows a micro "browser" in a wireless phone to link into a gateway
service in AT&T Wireless Group's network in such a way that web developers can
easily develop new services available to wireless phone users.

     In the second quarter of 2000, AT&T Wireless Group launched AT&T Digital
PocketNet service and two new phones that combine AT&T Wireless Group's tri-mode
voice capability with a CDPD modem and a micro browser in a single package. AT&T
Wireless Group first developed its own wireless data applications for phones
three years ago with the introduction of AT&T PocketNet service. AT&T Wireless
Group expects that the introduction of these new phones will accelerate the
adoption of AT&T Digital PocketNet service as well as drive the introduction of
new applications.

     AT&T Digital PocketNet service for businesses.  In the first quarter of
2000, AT&T Wireless Group introduced AT&T Digital PocketNet service for
businesses. This service allows corporations to build applications that provide
access to corporate intranet information to employees who are out of their
offices. Two key applications illustrate this service. The first is Mobile
Services for Domino, which is available from International Business Machines
Corporation/Lotus Development Corporation. This application provides for real
time access to Lotus Notes email, calendar and contacts from compatible phones
available from AT&T Wireless Group via AT&T Digital PocketNet service. The
second application provides similar capabilities using Microsoft Exchange email
and Outlook calendar/contacts information. AT&T Wireless Group is offering this
service in cooperation with Wireless Knowledge LLC. These applications open up
the ability for Lotus Notes and Microsoft Exchange users to have real time and
easy control of their email and other corporate information when away from their
offices. All of these are currently available at flat monthly rates, and can be
bundled with AT&T Digital One Rate service or any of AT&T Wireless Group's other
wireless voice rate plans.

     AT&T Digital PocketNet service for the consumer.  In May 2000, AT&T
Wireless Group announced the launch of a version of AT&T Digital PocketNet
service for the consumer. As with AT&T Digital PocketNet service for businesses,
these services provide unlimited usage at flat monthly rates. With the consumer
offer customers can browse a variety of consumer oriented branded and nonbranded
content including news, sports,
                                       79
<PAGE>   86

financial information, directories, directions, travel reservations and weather.
In addition, applications that allow consumer users to shop, access their
personal information, including contact lists and calendars, and read, write and
respond to emails are also available. AT&T Wireless Group currently offers
applications and services from over 70 content providers. In the third quarter
of 2000, AT&T Wireless Group announced that it has chosen Qpass to provide AT&T
Digital PocketNet subscribers the ability to easily and securely buy content,
goods and services via their Internet enabled phones.

     In the future, AT&T Wireless Group expects a number of additional
applications will be developed, including instant messaging shopping services
and services that are enhanced by information about the user's location. By
providing or facilitating such applications, AT&T Wireless Group believes it can
generate new revenue streams, as well as develop personalized relationships with
its customers.

     AT&T Text Messaging service.  For the last several years AT&T Wireless
Group has offered digital customers the ability to receive and store short
alphanumeric messages and pages right on their wireless phones. In October 2000,
AT&T Wireless Group launched AT&T Text Messaging service which allows customers
to send, receive and reply to short text messages from any compatible digital
wireless phone. AT&T Wireless Group provides customers the choice to either pay
on a per message basis or purchase a bucket of messages for use each month. AT&T
Text Messaging service also allows customers to receive updated news, sports,
weather and other relevant information in the form of short text messages.
Two-way text messaging is extremely popular in Europe and Asia and AT&T Wireless
Group views AT&T Text Messaging as important part of its overall offer portfolio
in the future.

     Products

     AT&T Wireless Group offers a variety of products as complements to its
wireless service, including handsets and accessories, such as chargers,
headsets, belt clips, faceplates and batteries.

     As part of its basic service offering, AT&T Wireless Group provides
easy-to-use, interactive menu-driven handsets that can be activated over the
air. These handsets primarily feature word prompts and menus rather than numeric
codes to operate handset functions. Some handsets allow mobile access to the
Internet. In addition, AT&T Wireless Group offers tri-mode handsets, which are
handsets compatible with PCS, digital cellular and analog cellular frequencies
and service modes. Tri-mode handsets permit customers to roam across a variety
of wireless networks and incorporate AT&T Wireless Group's IRDB system. AT&T
Wireless Group offers its customers use of Nokia, Ericsson, Mitsubishi and
Motorola handsets.

     Tri-mode handsets offer significantly extended battery life over earlier
technologies, providing up to 14 days of stand-by battery life. Handsets
operating on a digital system are capable of sleep-mode while turned on but not
in use, thus improving efficiency for incoming calls, as users will be able to
leave these phones on for significantly longer periods than they can with
wireless phones using an earlier technology. The use of tri-mode handsets
further extends battery life by using a digital system for roaming when in areas
covered by digital systems.

     Marketing

     AT&T Wireless Group develops customer awareness through its marketing and
promotion efforts and has been a leader in differentiating its products through
its use of targeted pricing plans and the introduction of new products and
services. AT&T Wireless Group also uses the AT&T brand name, provides superior
customer care and may continue to be able to engage in cross marketing
arrangements with the AT&T sales force and, when appropriate, to bundle its
service with the communications services offered by AT&T Common Stock Group
under the terms of agreements to take effect at the spin-off.

     Targeted marketing.  AT&T Wireless Group targets groups of customers who
share common characteristics or have common needs. Common characteristics may be
usage (frequent travelers), social group (families), age (youth market) or any
other distinctive measure. AT&T Wireless Group then attempts to create a
compelling offer by combining rate plans, products promotions and features that
meet the particular needs of that targeted group and that AT&T Wireless Group
can provide at a competitive advantage.

                                       80
<PAGE>   87

     The AT&T brand name.  AT&T Wireless Group prominently features the AT&T
brand name and logo on its products and services. AT&T Wireless Group has
benefited from AT&T's national advertising to build its brand awareness. AT&T
Wireless Group believes that the use of the AT&T brand name, one of the most
well known in the United States, will continue to be a distinct marketing
advantage.

     Customer care and support.  AT&T Wireless Group places a high priority on
providing its customers with the best customer care and support. J.D. Power and
Associates' 2000 U.S. Wireless Customer Satisfaction Survey rated AT&T Wireless
Group highest in overall customer satisfaction in nine out of 12 markets
studied. In two of the nine markets, AT&T Wireless Group was tied for first
place. AT&T Wireless Group employs approximately 8,300 customer care
representatives located in 14 call centers and contracts for outsourced customer
care service with approximately 3,000 additional representatives in nine
locations. In addition, subscribers can access their account and obtain answers
to routine inquiries through its website, www.att.com/wireless. Customers can
reach AT&T Wireless Group's customer care representatives or access its website
on a 24 hour/seven day a week basis for answers regarding their service,
activation, changing service plans and other service options. Customer care
representatives are accessible from any point within the network on an AT&T
Wireless Group handset at no charge or through any other telephone by calling a
toll-free number. In addition, certain large enterprise customers may utilize a
customized extranet for ease of customer service.

     As part of its customer care program, AT&T Wireless Group seeks to identify
higher value customers who are at risk of changing service providers. In these
cases, AT&T Wireless Group makes contact with the customers to address their
concerns, adjust their service plans or take other actions in an effort to
minimize the likelihood of such a change.

     Marketing with AT&T Common Stock Group.  AT&T Wireless Group has had the
opportunity to cross market with AT&T Common Stock Group's divisions and
capitalize on the size and breadth of AT&T Common Stock Group's customer base in
long distance and broadband service. In the event of the spin-off, AT&T Wireless
Services may continue to have certain marketing opportunities with AT&T, as set
forth in the terms of agreements to become effective at the time of the
spin-off.

  Sales and distribution

     AT&T Wireless Group markets its wireless services in its managed markets
under the AT&T brand name. It markets wireless services to business and
residential customers through a direct sales force of 2,100, through sales
points of presence in approximately 460 AT&T Wireless Group company-owned stores
located in 37 states, and kiosks and other customer points of presence,
including the Internet and inbound call centers, and through local and national
non-affiliated retailers throughout the United States. AT&T Common Stock Group
sales force may sell wireless services to business and residential customers as
part of bundled offerings with services of AT&T Common Stock Group when agreed
upon by the companies.

     AT&T Wireless Group also relies upon dealers to market its services in some
locations. Dealers are independent contractors that solicit customers for AT&T
Wireless Group service, and, typically, include specialized wireless stores,
specialized electronics stores and department stores. AT&T Wireless Group
generally pays its dealers a commission for each customer that uses its service
for a specified period, and may make residual or account management payments to
the dealer based on the customer's ongoing service charges.

     AT&T Wireless Group has begun a number of initiatives designed to lower its
costs of adding subscribers as well as its customer care expenses.

  Rates and billing

     AT&T Wireless Group charges may include fees for service activation,
monthly access, per-minute airtime and customer-calling features, which may
include a fixed number of minutes or packets of data per month at a set price
and generally offers a variety of pricing options, most of which combine a fixed
monthly access fee for a fixed number of minutes or packets of data and
additional charges for usage in excess of those allotted. Customers may also
incur long distance and roaming fees.

  Other assets

     AT&T Wireless Group also possesses certain other assets not described
above. The most significant of these assets include a number of equity interests
in international wireless operations and an air-to-ground wireless operation.

  International

     AT&T Wireless Group owns half of a 33.3% equity stake in Rogers Cantel, a
Canadian wireless communications company, which it holds jointly with British
Telecommunications. AT&T and British Telecommunications acquired this interest
in August 1999 for an aggregate of approximately Cdn$1.4 billion (US$934
million) in cash. This ownership position is held through a subsidiary entity
that is 50% owned by AT&T and 50% owned by British Telecommunications. AT&T and
British Telecommunications share four of the 16 Rogers Cantel board seats and
have been granted other governance rights customary in a transaction of this
nature.

     AT&T Wireless Group's long standing relationship with Rogers Cantel allows
two of North America's largest TDMA providers to offer cross-border
capabilities. Wireless customers throughout Canada can enjoy wireless services
under the Rogers AT&T Wireless name. This arrangement adds 28 million POPs to
AT&T Wireless Group's North American coverage.

     In the first quarter of 2000, AT&T Wireless Group was allocated a portion
of AT&T's interest in Japan Telecom, which provides local, long distance,
Internet and mobile wireless communications to businesses and consumers in
Japan. AT&T's interest in Japan Telecom is held through a 50% owned joint
venture with British Telecommunications. The joint venture owns 30% of Japan
Telecom. AT&T Wireless Group has been allocated 5% (i.e., one-sixth) of this 30%
stake. In the fourth quarter of 2000, the AT&T Wireless Services and AT&T
entered into a binding letter agreement with DoCoMo, a Japanese wireless
communications company, for DoCoMo's investment in AT&T representing an economic
interest in the AT&T Wireless Group and for the formation of a strategic
alliance. The parties signed final agreements for this investment on December
20, 2000. For more information, please see "Recent Developments -- DoCoMo
Strategic Investments" on page 40. As a result of this new wireless alliance, it
is anticipated that AT&T Wireless Group will seek to divest its interest in
Japan Telecom as promptly as commercially practicable.

     In October 2000, AT&T Wireless Group completed its acquisition of several
equity interests in international ventures acquired by AT&T as a result of its
acquisition of Media One in June 2000. AT&T Wireless Group paid approximately $1
billion to AT&T for these properties, which was based upon a third party
valuation. The following table provides information regarding these properties:

*  As of September 30, 2000.

** In the last quarter of 2000, Birla AT&T executed definitive documents for two
   transactions that will expand its coverage area in India. First, AT&T
   Wireless Group entered into an agreement to merge with the wireless
   operations of the Tata group. The Tata group has a cellular license for the
   Indian state of Andhra Pradesh. The transaction is awaiting governmental
   approval, which AT&T Wireless Group expects to receive in the first or second
   quarters of 2001. When closed the merger will create an enlarged company in
   which AT&T Wireless Group will own a 33% stake. In a second transaction,
   Birla AT&T and the Tata group agreed to jointly acquire for cash, 100% of the
   cellular license for the state of Madhay Pradesh. Upon closing, both
   transactions will increase the merged company's covered POPs to about
   63 million.

*** In September 2000, AT&T Wireless Group signed an agreement to exercise its
    options to purchase additional shares of stock in Far EasTone. In December
    2000, AT&T Wireless Group completed this transaction, investing an
    additional $205 million, resulting in a total ownership interest of 22.7%.

  Air-to-ground

     The Aviation Communications Division, or ACD, of AT&T Wireless Group
provides air-to-ground communications services. A minority ownership interest in
ACD is held by Rogers Cantel.

     ACD owns and operates a network of ground-based and airborne
telecommunications equipment and related assets that deliver digital telephone
service to commercial and private aircraft in North America. In the United
States and Canada, ACD currently contracts with Alaska Airlines, American
Airlines, Canadian Airlines, Delta Air Lines, Legend Airlines, Mid-west Express,
Northwest Airlines, and Southwest Airlines. ACD's North American installed
customer base represents 1,619 commercial aircraft. Outside the United States,
ACD is a supplier of airborne telecommunications equipment and product support
to airlines and other service providers. In Europe and Asia, ACD's current
installed customer base represents 371 commercial aircraft. Through its general
aviation segment, ACD provides digital telephone service to operators of private
aircraft. ACD currently has its system installed on 389 general aviation
aircraft.

     ACD's North American Terrestrial System network of 152 ground stations in
the United States, Canada and Mexico provides coverage on all major routes flown
by U.S. and Canadian commercial airlines customers equipped with ACD telephony
equipment. ACD's primary role in its international airline relationships has
been to install, integrate and support in-cabin telephone equipment on the
customer aircraft.

  Wireless network

     AT&T Wireless Group's ownership position in U.S. markets was obtained
through FCC comparative hearings, FCC auctions and the FCC lottery and
settlement process as well as through acquisitions of, and purchases and
exchanges of, operating systems and licenses from or with other wireless service
providers. AT&T Wireless Group continues to participate in FCC spectrum auctions
when commercially and strategically reasonable to do so. It may enter into
agreements with third parties with regard to participation in such

                                       83
<PAGE>   90

auctions, within the parameters legally permitted and disclosed to the extent
required by law. In addition to bidding in its own right, AT&T Wireless Group
has made certain commitments to provide funding for successful bids of Alaska
Native Wireless, L.L.C., up to agreed upon levels for the C and F Block
reauction (FCC Auction 35) which began December 12, 2000. AT&T Wireless Group
has a financial interest in Alaska Native Wireless. Auction participants' bids
are publicly available each auction day. Bidding can change dramatically in each
round of the auction, so being the high bidder at any point in the auction
offers no assurance of being the winner at the conclusion of the auction. At the
conclusion of the day's bidding on December 21, 2000, AT&T Wireless Group and
Alaska Native Wireless, collectively, held net high bids in the aggregate amount
of approximately $2.1 billion.

  Mobile wireless network

     Coverage.  As of September 30, 2000, AT&T Wireless Group's built network,
including partnership and affiliate markets, covered 97% of the U.S. population,
including operations in 48 of the 50 largest U.S. metropolitan areas. By
December 31, 2000, AT&T Wireless Group expects that its built network, including
partnership and affiliate markets, will cover 75% of the U.S. population. AT&T
Wireless Group's wireless network operates using both 850 megahertz and 1900
megahertz licenses. Where agreements are in place, AT&T Wireless Group is able
to offer service to customers of other wireless providers when they travel
through its service area, and AT&T Wireless Group subscribers can roam through
other wireless providers' service areas.

     Analog and digital technologies.  AT&T Wireless Group offers both analog
and digital service in its 850 megahertz markets and digital service in its 1900
megahertz markets. AT&T Wireless Group believes that digital technology offers
many advantages over analog technology, including substantially increased
network capacity, greater call privacy, enhanced services and features, lower
operating costs, reduced susceptibility to fraud and the opportunity to provide
improved data transmissions. Moving customers to digital service has been a key
component of AT&T Wireless Group's overall wireless strategy. Digital service
enables AT&T Wireless Group to provide added benefits and services to its
customers, including extended battery life, caller ID, text messaging and
voicemail with message waiting indicator.

     AT&T Wireless Group has pursued a strategy to convert its analog networks
and subscriber base to digital. The primary goals of this program are capacity
expansion, cost reduction, and product improvement. As of September 30, 2000,
over 87% of AT&T Wireless Group's consolidated subscribers use digital service,
accounting for over 94% of its traffic.

     As AT&T Wireless Group grows its customer base and adds new services and
applications, such as data services, it will need to increase its capacity in
order to support higher network traffic. Digital voice paths require less radio
frequency spectrum capacity than do analog voice paths. Further capacity
improvements are possible using other digital techniques and AT&T Wireless Group
believes that it is currently yielding from its digital mobile systems as much
as four times the capacity of an analog system using equivalent spectrum.
Further capacity improvements are possible using other digital techniques that
would yield as much as or more than six times analog capacity. AT&T Wireless
Group and its suppliers currently are developing and intend to deploy such
additional capacity-enhancing technology within its existing spectrum.

     AT&T Wireless Group intends to launch a national GSM platform, adding
GPRS/EDGE data services within its existing spectrum resources, and eventually
including UMTS largely using its existing spectrum resources. The deployment of
new technology is expected to be one factor that increases the spectrum
efficiency of AT&T Wireless Group's existing digital mobile network, in
combination with increased network capacity through cell site construction. AT&T
Wireless Group believes that its competitors that have not converted to digital
will not have the same flexibility in deploying high-speed data services.

     AT&T Wireless Group believes that its continued success depends on having a
competitive cost structure. In addition to enhancing capacity, digital
technology allows AT&T Wireless Group to produce network minutes with less
capital and operating expense than analog technology. Not only is the cost of
digital network equipment lower per voice path than analog network equipment,
but also fixed costs, such as towers, shelters and other common equipment, are
reduced by spreading them over a larger number of minutes.
                                       84

Digital has also allowed AT&T Wireless Group to improve its roaming costs
substantially using over-the-air programming, which enables phones to select the
most cost-effective roaming partners. AT&T Wireless Group believes that its
prompt implementation of digital technology gives it a cost advantage over its
competitors that are more dependent on analog.

     Moving customers to digital service is a key component of AT&T Wireless
Group's overall wireless strategy. Digital technology provides a host of feature
improvements to AT&T Wireless Group's customers. To date, AT&T Wireless Group
has delivered on its digital networks such features as caller ID, voicemail with
message waiting indicator, short alphanumeric message service, and Wireless
Office Service.

     TDMA network.  AT&T Wireless Group chose TDMA technology for its second
generation voice digital network, although it does operate a small number of
CDMA markets that were operating that technology when AT&T Wireless Group
acquired them. TDMA permits the use of advanced tri-mode handsets that allow for
roaming across analog and digital systems and across 850 megahertz and 1900
megahertz spectrums. TDMA digital technology allows for enhanced services and
features, such as short alphanumeric message service, extended battery life,
added call security and improved voice quality. TDMA's hierarchical cell
structure enables AT&T Wireless Group to enhance network coverage with lower
incremental investment through the deployment of micro and pico, as opposed to
macro, cell sites. This enables AT&T Wireless Group to offer customized billing
options and to track billing information per individual cell site, which is
practical for advanced wireless applications such as fixed wireless and wireless
office applications. TDMA served an estimated 54 million subscribers worldwide
and 27 million subscribers in North America as of September 30, 2000, according
to the Universal Wireless Communications Consortium, an association of TDMA
service providers and manufacturers. TDMA equipment is available from leading
telecommunication vendors such as Lucent, Ericsson and Nortel Networks Inc. A
number of other wireless service providers have chosen CDMA or GSM as their
current digital wireless technology. The AT&T Wireless Group intends to deploy
an overlay of GSM technology to its TDMA network, as part of its third
generation development strategy.

     AT&T Wireless Group is currently assessing the useful lives of its wireless
communications systems and anticipates that the lives of certain wireless
equipment will be shortened.

  CDPD network

     AT&T Wireless Group's CDPD network currently covers 104 million POPs, which
represents over 60% of its built network, and its CDPD customers can roam on the
CDPD networks of other wireless providers, which, together, cover an additional
74 million POPs. CDPD is an industry standard using Internet Protocol, which
allows most applications written for the Internet as well as many corporate
applications to run efficiently over the network without modification. Using
CDPD, data files and transactions are divided into small packets and sent on a
dedicated wireless channel. In many data applications, data is sent in bursts
with intermittent quiet periods. Packet transmission technologies take advantage
of this fact and allow user data to be efficiently carried on the same network
channel. As a result, relative to data services carried over circuit-switched
analog or digital wireless networks, AT&T Wireless Group's packet-switched CDPD
service is a significantly more cost-effective means of sending data for the
majority of applications because it allows many users to share the same channel.

  Third generation development strategy

     Third generation technologies will allow high-speed wireless packet data
services and ultimately voice services using Internet Protocol. AT&T Wireless
Group believes that a sound third generation strategy should allow the wireless
provider to achieve a pervasive footprint quickly and cost effectively. In
addition, AT&T Wireless Group believes third generation networks that achieve
global economies of scale and allow for global roaming will have a significant
advantage. AT&T Wireless Group had previously chosen TDMA-EDGE as its next
generation wireless architecture, to be deployed on its TDMA network platform,
as a means of accomplishing all of these goals. With this strategy, the AT&T
Wireless Group expected to be able to offer initial TDMA-EDGE services sometime
in 2002, with substantial deployment continuing into 2003.

                                       85
<PAGE>   92

     To accelerate the availability of third generation data services offerings,
AT&T Wireless Group recently announced plans to deploy a GSM platform to
facilitate the deployment of next generation technology including GPRS, EDGE,
and subsequently UMTS data services, as well as associated voice services. These
technologies will be deployed as an overlay on AT&T Wireless Group's TDMA voice
network. GSM platform deployment is planned to begin in the second half of 2001.
AT&T Wireless Group plans to make GPRS services available starting in 2001, and
EDGE is expected be available in 2002. AT&T Wireless Group currently plans to
deploy UMTS technology beginning in 2003, depending on the availability of
network equipment and customer devices. By making GPRS available in 2001, AT&T
Wireless Group expects to be able to make enhanced data services available to
customers earlier than its originally planned deployment of TDMA-EDGE in 2002.

     Due to its broad international acceptance, the GSM platform equipment
needed is readily available in the market. The overlay strategy also will allow,
AT&T Wireless Group to utilize its existing cell site facilities and spectrum.
Because of these efficiencies, the AT&T Wireless Group expects that its network
capital expenditures associated with the high speed data technology included in
its third generation plans over the period of deployment will be only modestly
greater than its earlier third generation migration plan, but may occur in
earlier periods.

     Like CDPD, GPRS, EDGE and UMTS are also Internet Protocol based. As a
result, AT&T Wireless Group expects that its near term use of its CDPD network
to develop innovative solutions will provide migration for its data customers.
AT&T Wireless Group expects that all the applications developed and deployed
today will migrate to GPRS and eventually to EDGE network services as customers
upgrade their equipment to GPRS and EDGE. With GPRS and EDGE, these applications
are expected to operate at higher speeds where deployed.

     This plan is expected to enable AT&T Wireless Group to provide customers
with earlier availability of a wide range of data service offerings on a broad
array of devices (phones, PDA's, laptops, etc.). AT&T Wireless Group plans to
sell handsets combining TDMA and GSM/GPRS/EDGE technology, which would provide
customers the benefit of access to AT&T Wireless Group's current voice network
as well as the new high-speed data services when available. Industry
specifications for the combined technology handsets were jointly developed by
the Universal Wireless Communications Consortium and the North American GSM
Alliance. AT&T Wireless Group is in discussions with manufacturers to develop
such devices.

     In November 2000, AT&T announced nonbinding letters of intent with
Ericsson, Lucent Technologies, Nokia and Nortel Networks for third generation
network equipment and, in the case of Nokia and Ericsson, for future generation
wireless customer terminals. AT&T Wireless Group has begun negotiating
definitive agreements with these and other vendors during the fourth quarter of
2000, has executed one of these agreements and expects to enter into binding
agreements as soon as practicable with the other vendors.

  Fixed Wireless

     Fixed wireless service provides customers with a high speed packet data
channel which can be used by up to five data devices simultaneously (for
example, five personal computers simultaneously accessing the Internet) at
download speeds of up to 512 kilobits per second. The service is expected to be
capable of speeds of up to one megabit per second by fourth quarter 2000. In the
future, the fixed wireless technology may evolve to provide higher than one
megabit of bandwidth per second. Currently, the offering provides expansion up
to four lines of wireline quality voice telephony, including custom calling
features (e.g., call waiting, caller ID, three-way calling) available today over
wireline networks.

     Both the data and voice channels are delivered over the existing telephone
wiring within the residence or small business premises, allowing customers to
utilize their existing telephones. No separate modem is required in order to
connect a customer's personal computer to the data channel. Once connected to
the existing telephone wiring within the premises, the fixed wireless equipment
(in combination with installation of third party hardware) supports multiple
simultaneous PC connections to the Internet within the premises. Data and
telephone equipment is connected within the premises using the standard jacks
that already exist on

                                       86
<PAGE>   93

the premises. All data transmissions are secured for customer privacy and fraud
protection by use of proprietary protocols. Voice transmissions are encrypted
for customer privacy and fraud protection.

     The data aspect of fixed wireless service will be further developed to
create an environment in which customers may select and easily change their
third party Internet service provider.

     In order to install fixed wireless service in a customer's premises, AT&T
Wireless Group must mount a flat panel antenna on the outside of a customer's
premises and certain electronic equipment, including a backup battery supply,
inside the premises. Once installed, the antenna on the customer's premises
communicates with a neighborhood antenna and base station that, in the majority
of cases, shares its physical location with an antenna and base station site
used to serve AT&T Wireless Group's mobile wireless service. Thus, in many cases
the mobile and fixed wireless networks will share a common infrastructure for
towers, base station sites and backhaul transmission to a digital switching
center.

     AT&T Wireless Group estimates the total capital cost to serve a subscriber
on the fixed wireless service currently is approximately $800 and expects this
cost to fall to about $550 within the next three to five years. These estimates
include the installed cost of all premises equipment as well as the installed
cost of any additional cell sites, antennas, base station equipment, backhaul
and switching equipment necessary to add the fixed wireless capability to AT&T
Wireless Group's mobile wireless infrastructure. The deployment of capital for
fixed wireless is flexible and can be actively managed. Approximately 65% of the
estimated capital cost is associated with the equipment installed on the
customer's premises and is not incurred until customers commit to purchase fixed
wireless services. The remaining 35% will only occur in targeted geographic
areas that AT&T Wireless Group believes offer the potential to be profitable
fixed wireless markets. Given this cost profile and the set of voice and data
capabilities provided by the fixed wireless system, AT&T Wireless Group believes
that it can create highly competitive market offers for the basic voice and
growing broadband data needs of residential and small business customers in any
market in which it chooses to deploy its fixed wireless solution. AT&T Wireless
Group believes that it can leverage AT&T's consumer sales channels to promote
its fixed wireless services to residential and small business customers.

     AT&T believes that AT&T Wireless Group is the most appropriate group to
take advantage of the fixed wireless opportunity for a number of reasons. First,
the fixed wireless network will share equipment and facilities with the mobile
wireless network, lowering the level of capital required to roll out the fixed
wireless service. Second, AT&T Wireless Group will take charge of the management
and sharing of wireless spectrum across business opportunities such as the core
mobility business, fixed wireless and the wireless data opportunity. Finally,
AT&T Wireless Group's management team has more experience to take advantage of
the opportunity, given the technical expertise and knowledge it has accumulated
building the mobile wireless network.

COMPETITION

     Competition for subscribers among wireless service providers is based
principally upon the services and features offered, call quality, customer
service, system coverage and price. AT&T Wireless Group's ability to compete
successfully will depend, in part, on its ability to anticipate and respond to
various competitive factors affecting the industry, including new services that
may be introduced, changes in consumer preferences, demographic trends, economic
conditions and pricing strategies. AT&T Wireless Group's primary national
competitors are Cingular, Verizon Wireless, Nextel Communications, Inc.,
VoiceStream Communications and Sprint PCS.

     In addition, the wireless communications industry has been experiencing
significant consolidation and the AT&T Wireless Group expects that this
consolidation will continue. The previously announced, or recently completed,
mergers or joint ventures of Bell Atlantic/GTE/Vodafone/AirTouch (now called
Verizon), SBC/ Bell South/Ameritech (now called Cingular) have created large,
well-capitalized competitors with substantial financial, technical, marketing
and other resources to respond to AT&T Wireless Group's offerings. In addition,
in July 2000, VoiceStream Communications and Deutsche Telecom announced a
proposed transaction. These mergers or ventures have caused AT&T Wireless
Group's ranking to decline to third in U.S. revenue and U.S. subscriber share.
In terms of U.S. population covered by licenses, or POPs, AT&T
                                       87
<PAGE>   94

Wireless Group, including partnerships and affiliates, ranks third. As a result,
these competitors may be able to offer nationwide services and plans more
quickly and more economically than the AT&T Wireless Group and to obtain roaming
rates that are more favorable than those obtained by AT&T Wireless Group, and
may be better able to respond to offers of AT&T Wireless Group.

     AT&T Wireless Group's cellular operations have always experienced direct
competition from the second cellular licensee in each market. Beginning in 1997,
AT&T Wireless Group began experiencing competition from as many as six license
holders in certain markets. Competition from new providers in AT&T Wireless
Group's markets will continue to increase as the networks of license holders are
built out over the next several years. In addition, the FCC is likely to offer
additional spectrum for wireless mobile licenses in the future using existing or
new technologies.

PATENTS AND TRADEMARKS

     AT&T and AT&T Wireless Group and their subsidiaries own numerous patents in
the United States and foreign countries. The foreign patents are generally
counterparts of the U.S. patents. Many of these patents are licensed to others
and AT&T, the AT&T Wireless Group and their subsidiaries are licensed to use
certain patents licensed from others. Until now, patents sometimes have been
managed by the AT&T group originating or utilizing the patent, and sometimes
have been managed by a different AT&T group; patents utilized by AT&T Wireless
Group have been managed by the group that has managed it historically. In the
event of a spin-off, AT&T Common Stock Group and AT&T Wireless Services will
cross-license to each other their patents owned as of the time of the spin-off
as well as certain patents issuing from patent applications pending at the time
of the spin-off. This arrangement is intended to preserve each group's right to
use the patents managed by the other group, or with respect to which either has
the power to grant such rights, for appropriate business activities. We expect
there will be no royalty or licensing fees related to these arrangements for
patents owned by the respective group.

     The groups have collaborated to achieve enterprise objectives with respect
to the licensing or sale of patents to third parties. The policy of AT&T
Wireless Group capital stock committee has been not to sell or license any
patents that are predominantly used by AT&T Wireless Group if that sale or
license would result in a material competitive disadvantage to AT&T Wireless
Group. Any fees obtained through such sales or licensing would be allocated to
the group that predominantly uses the patents sold or licensed, or if no
specific patent can be associated with a fee or such patent is not predominantly
used by any one group, then allocated using the same general allocation as
overhead expenses. AT&T Wireless Group does not consider any individual patents
to be material to its business operation.

     AT&T has numerous trademarks registered throughout the world. AT&T
considers many of its trademarks to be valuable assets, particularly the AT&T
brand name and globe logo. AT&T Wireless Group currently has access to these
trademarks, including the AT&T brand name and globe logo, in the United States
and other countries under the same terms as for the patents described above. In
the event of a spin-off, AT&T Wireless Services will be licensed by AT&T to use
a number of AT&T's trademarks that it has been using to date, including the AT&T
brand name and globe logo. It is expected that the initial term of the license
will be five years, with the right by AT&T Wireless Services to renew the
license for an additional five years. The license will be royalty free, but will
include a brand maintenance fee computed as a percentage of AT&T Wireless
Services' gross revenue on services using the licensed trademarks. That
percentage during the initial term declines over one or two year increments;
and, during the renewal term, the percentage remains at the percentage set for
the final year of the initial term. This license will be exclusive and
world-wide for wide-area mobile cellular wireless services, with the exception
of certain countries in which AT&T has already licensed the brand for these
services. The license to use the brand for fixed wireless is non-exclusive and
is limited to residential markets, and if certain preconditions are met, the
license may be extended to small business markets; but in neither case does the
license extend to the service areas of cable systems owned and operated by AT&T
(other than in certain areas of Dallas, Texas) or in which AT&T has an
attributable ownership interest, or to certain designated market areas.

                                       88
<PAGE>   95

     In total, these patents, patent applications, trademarks and licenses are
material to AT&T Wireless Group's business.

EMPLOYEES

     As of September 30, 2000, AT&T Wireless Group employed approximately 27,000
individuals in its operations, including its fixed wireless operations,
virtually all of whom are located in the United States.

PROPERTIES

     AT&T Wireless Group owns, or controls through long-term leases or licenses,
properties consisting of plant and equipment used to provide wireless
communications services. In addition, it owns, or controls through leases,
properties used as administrative office buildings and/or retail sales
locations, customer care centers, and other facilities, such as research and
development facilities. These properties include land, interior and rooftop
office space, and space on existing structures of various types used to support
equipment used to provide wireless communications services. Most of the leased
properties are owned by private entities and the balance is owned by municipal
entities.

     Plant and equipment used to provide wireless communications services
consist of:

     - switching, transmission and receiving equipment,

     - connecting lines (cables, wires, poles and other support structures,
       conduits, etc.),

     - land and buildings,

     - easements, and

     - other miscellaneous properties (work equipment, furniture and plants
       under construction).

     The majority of the lines connecting AT&T Wireless Group services to other
telecommunications services and power sources are on or under public roads,
highways and streets. The remainder are on or under private property.

REGULATORY ENVIRONMENT

     The FCC regulates the licensing, construction, operation, acquisition, sale
and resale of wireless systems in the United States pursuant to the
Communications Act of 1934 and the associated rules, regulations and policies
promulgated by the FCC.

  Licensing of wireless services systems

     AT&T Wireless Group owns protected geographic service area licenses granted
by the FCC to provide cellular service and PCS. It also owns licenses granted by
the FCC to provide point-to-multi-point communications services in various
bands, including significant licenses in the 37 to 39 gigahertz bands.

     A cellular system operates on one of two 25 megahertz frequency blocks that
the FCC allocates for cellular radio service. Cellular systems generally are
used for two-way mobile voice applications, although they may be used for data
applications and fixed wireless services as well. Cellular license areas are
issued for either metropolitan service areas or rural service areas. Initially,
one of the two cellular licenses available in each metropolitan service area or
rural service area was awarded to a local exchange telephone company by the FCC,
while the other license was awarded either through competitive processes or
lotteries. Licenses were issued beginning in 1983, and over the years numerous
license transfers and corporate reorganizations have obscured the original
pattern of distributing one set of licenses to local telephone company
affiliates and the other to companies that do not have local exchange service in
the license area.

     A PCS system operates on one of six frequency blocks allocated for personal
communications services. PCS systems generally are used for two-way voice
applications although they may carry two-way data communications as well.
Narrowband PCS systems, in contrast, are for non-voice applications such as
paging and data service and are separately licensed. For the purpose of awarding
PCS licenses, the FCC has segmented the United States into 51 large regions
called major trading areas, which are comprised of 493 smaller regions called
basic trading areas. The FCC awarded two PCS licenses for each major trading
area and four licenses for each basic trading area. The two major trading area
licenses authorize the use of
                                       89
<PAGE>   96

30 megahertz of spectrum. One of the basic trading area licenses is for 30
megahertz of spectrum, and the other three are for 10 megahertz each. The FCC
permits licensees to split their licenses and assign a portion, on either a
geographic or frequency basis or both, to a third party.

     The FCC awarded initial PCS licenses by auction. Auctions began with the 30
megahertz major trading area licenses and concluded in 1998 with the last of the
basic trading area licenses. However, in March 1998, the FCC adopted an order
that allows troubled entities that won PCS 30 megahertz C-Block licenses at
auction to obtain financial relief from their payment obligations and to return
some or all of their C-Block licenses to the FCC for reauctioning. The FCC
completed the reauction of the returned licenses in April 1999. In addition,
certain of the C-block licenses are currently in bankruptcy proceedings. The FCC
has cancelled some of these licenses, and has scheduled a reauction which began
in December 2000. The FCC's cancellation of the licenses has been challenged by
one of the bankrupt licensees, and there is no guarantee that the reauction or
the award of any licenses pursuant to the reauction will not be affected by this
challenge.

     Under the FCC's current rules specifying spectrum aggregation limits
affecting wireless licensees, no entity may hold attributable interests,
generally 20% or more of the equity of, or an officer or director position with,
the licensee, in licenses for more than 45 megahertz of PCS, cellular and
certain specialized mobile radio services where there is significant overlap in
any geographic area. Significant overlap will occur when at least 10% of the
population of the PCS licensed service area is within the cellular and/or
specialized mobile radio service area(s). The FCC recently increased this limit
to 55 megahertz in situations in which a 25 megahertz cellular rural service
area is attributed to a 30 megahertz PCS license. These spectrum aggregation
rules are subject to a pending FCC proceeding that could revise or eliminate
them.

     All wireless licenses have a 10-year term, at the end of which term they
must be renewed. The FCC will award a renewal expectancy to a wireless licensee
that has provided substantial service during its past license term, and has
substantially complied with applicable FCC rules and policies and the
Communications Act. Licenses may be revoked for cause and license renewal
applications denied if the FCC determines that a renewal would not serve the
public interest. FCC rules provide that competing renewal applications for
licenses will be considered in comparative hearings, and establish the
qualifications for competing applications and the standards to be applied in
hearings.

     All wireless licenses must satisfy specified coverage requirements.
Cellular licenses were required, during the five years following the grant of
the license, to construct their systems to provide service (at a specified
signal strength) to the territory encompassed by their service area. Failure to
provide such coverage resulted in reduction of the relevant license area by the
FCC. All A and B block PCS licensees must construct facilities that offer
coverage to one-third of the population of the service area within five years of
the original license grants and to two-thirds of the population within ten
years. All D and E block PCS licensees must construct facilities that offer
coverage to one-fourth of the population of the licensed area or "make a showing
of substantial service in their license area" within five years of the original
license grants. Other point-to-multi-point licenses require a showing of
substantial service at renewal. Licensees that fail to meet the coverage
requirements may be subject to forfeiture of the license.

     In an effort to balance the competing interests of existing microwave users
in the PCS bands and newly authorized PCS licensees, the FCC has adopted a
transition plan to relocate such microwave operators to other spectrum blocks
and a cost sharing plan so that if the relocation of an incumbent benefits more
than one PCS licensee, those licensees will share the cost of the relocation.
Initially, this transition plan allowed most microwave users to operate in the
PCS spectrum for a voluntary two-year negotiation period and an additional
mandatory one-year negotiation period. For public safety entities that dedicate
a majority of their system communications to police, fire or emergency medical
services operations, the voluntary negotiation period is three years, with an
additional mandatory two-year negotiation period. In 1998, the FCC shortened the
voluntary negotiation period by one year, without lengthening the mandatory
negotiation period, for non-public safety PCS licensees in the C, D, E and F
Blocks. Parties unable to reach agreement within these time periods may refer
the matter to the FCC for resolution, but the incumbent microwave user is
permitted to continue its operations until final FCC resolution of the matter.
The transition and cost sharing plans expire on April 4, 2005, at which time
remaining microwave incumbents in the PCS spectrum will be responsible for the
costs of relocating to alternate spectrum locations.

                                       90
<PAGE>   97

     Wireless systems are subject to certain FAA regulations governing the
location, lighting and construction of transmitter towers and antennas and are
subject to regulation under federal environmental laws and the FCC's
environmental regulations. State or local zoning and land use regulations also
apply to tower siting and construction activities. We expect to use common
carrier point-to-point microwave facilities to connect certain wireless cell
sites, and to link them to the main switching office. The FCC licenses these
facilities separately and they are subject to regulation as to technical
parameters and service.

     The Communications Act preempts state and local regulation of the entry of,
or the rates charged by, any provider of private mobile radio service or of
commercial mobile radio service, which includes PCS and cellular service. The
FCC does not regulate commercial mobile radio service or private mobile radio
service rates. However, commercial mobile radio service providers are common
carriers and are required under the Communications Act to offer their services
to the public without unreasonable discrimination. The FCC's rules currently
require providers to permit others to resell their services for a profit;
however, these rules will expire in 2002.

  Transfers and assignments of cellular and PCS licenses

     The Communications Act and FCC rules require the FCC's prior approval of
the assignment or transfer of control of a license for a PCS or cellular system.
In addition, the FCC has established transfer disclosure requirements that
require licensees who assign or transfer control of a PCS license within the
first three years of their license terms to file associated sale contracts,
option agreements, management agreements or other documents disclosing the total
consideration that the licensee would receive in return for the transfer or
assignment of its license. Non-controlling interests in an entity that holds an
FCC license generally may be bought or sold without FCC approval subject to the
FCC's spectrum aggregation limits. However, notification and expiration or
earlier termination of the applicable waiting period under Section 7A of the
Clayton Act by either the Federal Trade Commission or the Department of Justice
may be required, as well as approval by state or local regulatory authorities
having competent jurisdiction, if we sell or acquire PCS or cellular interests
over a certain size.

  Foreign ownership

     Under existing law, no more than 20% of an FCC licensee's capital stock may
be owned, directly or indirectly, or voted by non-U.S. citizens or their
representatives, by a foreign government or its representatives or by a foreign
corporation. If an FCC licensee is controlled by another entity, as is the case
with our ownership structure, up to 25% of that entity's capital stock may be
owned or voted by non-U.S. citizens or their representatives, by a foreign
government or its representatives or by a foreign corporation. Foreign ownership
above the 25% level may be allowed should the FCC find such higher levels not
inconsistent with the public interest. The FCC has ruled that higher levels of
foreign ownership, even up to 100%, are presumptively consistent with the public
interest with respect to investors from certain nations. If our foreign
ownership were to exceed the permitted level, the FCC could revoke our FCC
licenses, although we could seek a declaratory ruling from the FCC allowing the
foreign ownership or take other actions to reduce our foreign ownership
percentage in order to avoid the loss of our licenses. We have no knowledge of
any present foreign ownership in violation of these restrictions.

  Recent regulatory developments

     The FCC has announced rules for making emergency 911 services available by
cellular, PCS and other commercial mobile radio service providers, including
enhanced 911 services that provide the caller's telephone number, location and
other useful information. The original timetable required commercial mobile
radio services providers to be able to process and transmit 911 calls without
call validation, including those from callers with speech or hearing
disabilities, by late 1997. Additionally, commercial mobile radio service
providers are required to take actions enabling them to relay a caller's
automatic number identification and cell site if requested to do so by a public
safety dispatch agency that agreed to reimburse the provider for the additional
expenses incurred to provide those services. In December 1999, the FCC revised
its rules to eliminate any requirement that such agencies reimburse wireless
providers. In another order issued earlier in October 1999, the FCC also
modified rules requiring commercial mobile radio service providers to provide

                                       91
<PAGE>   98

information on the location of a 911 call. The modified rules allow providers to
use either network or handset-based technologies to provide such information.
However, providers are not permitted to recover their costs of deploying such
technologies from dispatch agencies. The FCC has granted waivers of the
requirement to provide 911 service to users with speech or hearing disabilities
to various providers, and we have obtained a waiver. On June 9, 1999, the FCC
also adopted rules designed to ensure that analog cellular calls to 911 are
completed. These rules, which do not apply to digital cellular service or to
PCS, give each cellular provider a choice of three ways to meet this
requirement. State actions incompatible with the FCC rules are subject to
preemption.

     On August 8, 1996, the FCC released its order implementing the
interconnection provisions of the Telecommunications Act. Although many of the
provisions of this order were struck down by the U.S. Court of Appeals for the
Eighth Circuit, on January 25, 1999, the U.S. Supreme Court reversed the Eighth
Circuit and upheld the FCC in all respects material to our operations. On June
10, 1999, the Eighth Circuit issued an order requesting briefs on certain issues
it did not address in its earlier order, including the pricing regime for
interconnection. While appeals have been pending, the rationale of the FCC's
order has been adopted by many states' public utility commissions, with the
result that the charges that cellular and PCS operators pay to interconnect
their traffic to the public switched telephone network have declined
significantly from pre-1996 levels. In July 2000, the Eighth Circuit rejected
certain aspects of the FCC's pricing methodology, but stayed its order pending
appeal by affected parties to the U.S. Supreme Court. The FCC and some carriers
are seeking review of the Eighth Circuit's order in the U.S. Supreme Court.

     In its implementation of the Telecommunications Act, the FCC established
federal universal service requirements that affect commercial mobile radio
service operators. Under the FCC's rules, commercial mobile radio service
providers are potentially eligible to receive universal service subsidies for
the first time; however, they are also required to contribute to the federal
universal service fund and can be required to contribute to state universal
funds. Many states are moving forward to develop state universal service fund
programs. A number of these state funds require contributions, varying greatly
from state to state, from commercial mobile radio service providers. The FCC's
universal service order was modified on appeal in the U.S. Court of Appeals for
the Fifth Circuit. The court's ruling has had the effect of reducing commercial
mobile radio service provider support payments required for the federal
universal service programs. The U.S. Supreme Court has agreed to address the
constitutionality of the FCC's universal service order, in particular as it
affects the amount of funds to which telephone companies are entitled to help
defray the costs of providing basic telephone service. The Court's determination
may also affect the FCC's interconnection pricing methodology.

     On August 1, 1996, the FCC released a report and order expanding the
flexibility of cellular, PCS and other commercial mobile radio service providers
to provide fixed as well as mobile services. These fixed services include, but
need not be limited to, wireless local loop services, for example, to apartment
and office buildings, and wireless backup services to private branch exchange or
switchboards and local area networks, to be used in the event of interruptions
due to weather or other emergencies. The FCC declined to render a prospective
ruling on whether fixed services provided on a co-primary basis with mobility
services should be subjected to universal service obligations, or how such fixed
services should be regulated. Rather, it has announced its intention to decide
such matters on a case-by-case basis depending on the characteristics of a
provider's fixed service offering. If the fixed services are provided as an
ancillary service to a carrier's mobility services, the FCC has decided that
such fixed services should be regulated as commercial mobile radio services. The
FCC has been presented with one such case, but has not yet ruled on it. It is
unclear what effect, if any, such a ruling would have on the business of AT&T
Wireless Group.

     The FCC has adopted rules on telephone number portability that will enable
customers to migrate their landline and cellular telephone numbers to cellular
or PCS providers and from a cellular or PCS provider to another service
provider. On February 8, 1999, the FCC extended the deadline for compliance with
this requirement to November 24, 2002, subject to any later determination that
number portability is necessary to conserve telephone numbers. The FCC has also
adopted rules requiring cellular and PCS providers to provide certain functions
to facilitate electronic surveillance by law enforcement officials by June 30,
2000. Carriers must be able to provide additional surveillance capabilities by
September 30, 2001. AT&T Wireless Group has

                                       92
<PAGE>   99

sought permission for a flexible deployment schedule from the FCC. The FCC has
not ruled on the request and there can be no assurance that the FCC will grant
the request. In addition, in August 2000, the U.S. Court of Appeals for the
District of Columbia Circuit invalidated some of these rules and remanded them
to the FCC for further consideration. Various other petitions are pending before
the FCC seeking suspension or further extensions of the deadlines applicable to
providing surveillance capabilities. It is not known how the FCC will revise its
rules or whether it will extend either or both of the compliance deadlines or
what the scope of penalties for failing to comply may be.

     In 1997, the FCC determined that the rate integration requirement of the
Communications Act applies to the interstate, interexchange services of
commercial mobile radio service providers. Rate integration requires a carrier
to provide service between the continental U.S. and offshore U.S. states and
territories under the same rate structure applicable to service between two
points in the continental U.S. The FCC delayed implementation of the rate
integration requirements with respect to wide area rate plans we offer pending
further reconsideration of its rules. The FCC also delayed the requirement to
integrate commercial mobile radio service long distance rates among commercial
mobile radio service affiliates. On December 31, 1998, the FCC reaffirmed, on
reconsideration, that its interexchange rate integration rules apply to
interexchange commercial mobile radio service services. The FCC announced it
would initiate a further proceeding to determine how integration requirements
apply to typical commercial mobile radio service offerings, including one-rate
plans. In July 2000, the U.S. Court of Appeals for the District of Columbia
Circuit reversed the FCC's holding that the Communications Act unambiguously
extends rate integration to providers of commercial mobile services. The court
remanded the matter to the FCC for further consideration. Pending conclusion of
this further proceeding, the rate integration requirement does not apply to
commercial mobile services. To the extent that AT&T Wireless Group is required
to offer services subject to the FCC's rate integration requirements, its
pricing flexibility will be reduced. We cannot assure you that the FCC will
decline to impose rate integration requirements on AT&T Wireless Group or
decline to require it to integrate its commercial mobile radio service long
distance rates across its commercial mobile radio service affiliates.

     In 1998, the FCC adopted new rules limiting the use of customer proprietary
network information by telecommunications carriers in marketing a broad range of
telecommunications and other services to their customers and the customers of
affiliated companies. The rules were struck down by the U.S. Court of Appeals
for the Tenth Circuit in 1999, and their effectiveness has been stayed pending
the court's review of a petition to the FCC for reconsideration. Even if the
rules are reinstated, AT&T Wireless Group does not anticipate that they will
result in a significant adverse impact on its financial position, results of
operation or liquidity.

     State commissions have become increasingly aggressive in their efforts to
conserve numbering resources. Examples of state conservation methods include:
number pooling, number rationing and code sharing. A number of states have
petitioned the FCC for authority to adopt "technology specific" overlays that
would require wireless providers to obtain telephone numbers out of a separate
area code and may require wireless providers to change their customers'
telephone numbers. These efforts may impact wireless service providers by
imposing additional costs or limiting access to numbering resources.

     The FCC has adopted detailed billing rules for landline telecommunications
service providers and applied a number of these rules to commercial mobile radio
services providers. It is considering whether to extend the remaining rules to
commercial mobile service providers as well. The FCC may require that more
billing detail be provided to consumers, which could add to the expense of the
billing process as systems are modified to conform to any new requirements. The
FCC also is considering whether carriers that decide to pass through their
mandatory universal service contributions to their customers should be required
to provide a full explanation of the program, and whether to ensure that the
carriers that pass through their contribution do not recover amounts greater
than their mandatory contributions from their customers. Adoption of some of the
FCC's proposals could increase the complexity of our billing processes and
restrict our ability to bill customers for services in the most commercially
advantageous way.

     The FCC has adopted an order that determines the obligations of
telecommunications carriers to make their services accessible to individuals
with disabilities. The order requires telecommunications services providers to
offer equipment and services that are accessible to and useable by persons with
disabilities. While

                                       93
<PAGE>   100

the rules exempt telecommunications carriers from meeting general disability
access requirements if such results are not readily achievable, it is not clear
how liberally the FCC will construe this exemption. Accordingly, the rules
require us to make material changes to our network, product line, or services at
our expense.

     In June 1999, the FCC initiated an administrative rulemaking proceeding to
help facilitate the offering of calling party pays as an optional wireless
service. Under the calling party pays service, the party placing the call to a
wireless customer pays the wireless airtime charges. Most wireless customers in
the United States now pay both to place calls and to receive them. Adoption of a
calling party pays system on a widespread basis could make commercial mobile
radio service providers more competitive with traditional landline
telecommunications providers for the provision of regular telephone service.

     The FCC has adopted rules specifying standards and the methods to be used
in evaluating radiofrequency emissions from radio equipment, including network
equipment and handsets used in connection with commercial mobile radio service.
These rules were upheld on appeal by the U.S. Court of Appeals for the Second
Circuit, but a number of parties have asked the U.S. Supreme Court to review the
Second Circuit's decision. AT&T Wireless Group's network facilities and the
handsets it sells to customers comply with these standards.

     Media reports have suggested that some radio frequency emissions from
wireless handsets may be linked to health concerns, including the incidence of
cancer. Although some studies have suggested that radio frequency emissions may
cause certain biological effects, all of the expert reviews conducted to date
have concluded that the evidence does not support a finding of adverse health
effects but that further research is appropriate. Earlier this year, CTIA
entered into a Cooperative Research and Development Agreement to sponsor such
research.

     Studies have shown that some hand-held digital telephones may interfere
with some medical devices, including hearing aids and pacemakers. The FDA has
recently issued guidelines for the use of wireless phones by pacemaker wearers.
Additional studies are underway to evaluate and improve the compatibility of
hearing aids and digital wireless phones.

  State and local regulation

     State and local governments are preempted from regulating either market
entry by, or the rates of, wireless operators. However, state governments can
regulate other terms and conditions of wireless service and several states have
imposed, or have proposed legislation that will impose, various consumer
protection regulations on the wireless industry. As noted above, States also may
impose their own universal service support regimes on wireless and other
telecommunications carriers, similar to the requirements that have been
established by the FCC and have been delegated certain authority by the FCC in
the area of number allocation and administration. At the local level, wireless
facilities typically are subject to zoning and land use regulation. However,
under the federal Telecommunications Act, neither local nor state governments
may categorically prohibit the construction of wireless facilities in any
community or unreasonably discriminate against a carrier. Numerous State and
local jurisdictions have considered imposing conditions on a driver's use of
wireless technology while operating a motor vehicle, and a few have actually
done so.

LEGAL PROCEEDINGS

     Several lawsuits have been filed asserting claims that AT&T Wireless Group
collected charges for local government taxes from customers that were not
properly subject to those charges. AT&T Wireless Group has entered into a
settlement of one of these cases, although the settlement has been challenged on
appeal. AT&T Wireless Group has asserted in those cases that any recovery should
come from the municipalities to which the taxes were paid.

     Several class action lawsuits have been filed in which claims have been
asserted that AT&T Wireless Group did not have sufficient network capacity to
support the influx of new subscribers who signed up for AT&T Digital One Rate
service beginning in May 1998 and therefore has failed to provide service of a
quality allegedly promised to subscribers. The plaintiffs in these cases have
not asserted specific claims for damages, with the exception of one case filed
in Texas in which the named plaintiffs have asserted claims for compensatory and
punitive damages totaling $100 million.

                                       94
<PAGE>   101

     Several other class action or representative lawsuits have been filed
against AT&T Wireless Group that allege, depending on the case, breach of
contract, misrepresentation or unfair practice claims relating to AT&T Wireless
Group's billing practices (including rounding up of partial minutes of use to
full minute increments and billing send to end), coverage, dropped calls, price
fixing and/or mistaken bills. Although the plaintiffs in these cases have not
specified alleged damages, the damages in two of the cases are alleged to exceed
$100 million. One of these two cases was dismissed and the dismissal was
affirmed in part on appeal. Settlement negotiations are ongoing in both cases.

     AT&T Wireless Group is involved in litigation in which the Cellular One
Group claims that use of the name "AT&T Digital One Rate" infringes a
trademarked name, "DIGITALONE" for which the Cellular One Group has obtained
trademark registration. The Cellular One Group has not specified amounts of
claimed damages.

     AT&T Wireless Group is involved in a patent infringement action against GTE
in the U.S. District Court in Seattle, Washington. GTE claims that the Nokia
phones manufactured for AT&T Wireless Group infringe a GTE patent for
over-the-air activation and over-the-air programming. AT&T Wireless Group is
seeking a declaratory judgment that its use of over-the-air activation does not
infringe GTE's patent. GTE has not specified amounts of claimed damages.

     AT&T Wireless Group is involved in an international arbitration proceeding
concerning interests in a Malaysian telecommunications joint venture, Maxis
Communications Bhd, a former MediaOne business acquired by AT&T and sold to AT&T
Wireless Group in the fourth quarter of 2000. In the arbitration, a group of
Malaysian shareholders claim that MediaOne breached fiduciary duties and
contractual obligations owed to the joint venture. The arbitration claim asserts
damages of $400 million. If the spin-off is completed, AT&T Wireless Services
will assume a portion of the liabilities, if any, relating to this action,
subject to certain adjustments.

     Stockholders of a former competitor of AT&T Wireless Group air-to-ground
business are plaintiffs in a lawsuit filed in 1993, alleging that AT&T Wireless
Group breached a confidentiality agreement, used trade secrets to unfairly
compete, and tortiously interfered with the business and potential business of
the competitor. Plaintiffs sought damages in an unspecified amount in excess of
$2.5 billion dollars. AT&T Wireless Group obtained partial summary judgment and
then prevailed on the remainder of the claims at a trial on the validity of a
release of plaintiffs' claims. Final judgment was entered against plaintiffs on
their claims, and plaintiffs appealed. On appeal, the Appellate Court of
Illinois, Second District, reversed and remanded the case for trial indicating
that certain issues decided by the judge needed to be resolved by a jury.

     AT&T Wireless Group is vigorously defending each of these claims. AT&T
Wireless Group cannot predict the final outcome of these disputes, but does not
believe that it will suffer any material liability from them.

     Several lawsuits have been filed against AT&T, certain executives of AT&T
and a group of investment banking firms, seeking class certification and
asserting claims under federal securities laws. The complaints assert claims
that AT&T made material misstatements concerning the company's earnings and
financial condition, while omitting other material information, allegedly to
maximize proceeds from the initial public offering of AT&T Wireless Group
tracking stock in April 2000 and/or to avoid paying a cash guarantee in
connection with the MediaOne acquisition. The complaints do not specify amounts
of damages claimed, although the plaintiffs are seeking to recover for declines
in stock prices of AT&T securities, including the AT&T Wireless Group tracking
stock. In connection with the spin-off, AT&T Wireless Group is expected to be
allocated a portion of the liabilities, if any, arising out of these actions to
the extent relating to AT&T Wireless Group tracking stock.

     AT&T Wireless Group also is a defendant in other legal actions involving
claims incidental to the normal conduct of the running of its business. AT&T
Wireless Group believes that the amounts that may be paid in these actions will
not be material to its financial position, or its results of operations or cash
flow.

                  RELATIONSHIP BETWEEN AT&T COMMON STOCK GROUP
                 AND AT&T WIRELESS GROUP PRIOR TO THE SPIN-OFF

     The description of the AT&T Wireless Group capital stock committee and the
AT&T Wireless Group policy statement below is not complete and is qualified in
its entirety by reference to AT&T's by-laws and the AT&T Wireless Group policy
statement. For information on how to obtain these documents, see "Where You Can
Find More Information" on page 135. You are urged to read them in their
entirety.

AT&T WIRELESS GROUP CAPITAL STOCK COMMITTEE

     The AT&T Wireless Group capital stock committee of our board of directors
oversees the interaction between the businesses of the AT&T Common Stock Group
and the AT&T Wireless Group. The members of the AT&T Wireless Group capital
stock committee are selected by our board of directors. AT&T's by-laws provide
that AT&T's board of directors has delegated to the AT&T Wireless Group capital
stock committee authority to:

     - interpret, make determinations under and oversee the implementation of
       the policies described in the Policy Statement Regarding AT&T Wireless
       Group Tracking Stock Matters described under "-- AT&T Wireless Group
       Policy Statement,"

     - review the policies, programs and practices of AT&T relating to:

        -- the business and financial relationships between AT&T or any of its
           units, other than Liberty Media Group, with AT&T Wireless Group,

        -- dividends in respect of, disclosures to shareholders and the public
           concerning, and transactions by AT&T or any of its subsidiaries,
           other than subsidiaries included in Liberty Media Group, in shares of
           AT&T Wireless Group tracking stock, and

        -- any matters arising in connection with any of the foregoing, all to
           the extent the AT&T Wireless Group capital stock committee may deem
           appropriate, and

     - recommend changes in the policies, programs and practices that the AT&T
       Wireless Group capital stock committee may deem appropriate.

     The AT&T Wireless Group capital stock committee will have and may exercise
such other powers, authority and responsibilities as our board of directors may
determine from time to time. Although our board of directors has no present
intention to do so, it may modify, suspend or rescind AT&T's by-laws or adopt
additional by-laws, at any time, without the approval of our shareholders,
subject to our board of directors' fiduciary duties. Pursuant to the terms of
the DoCoMo investment, prior to the spin-off DoCoMo has the right to appoint one
member of the AT&T board who will be entitled to serve as a member of the AT&T
Wireless Group capital stock committee.

AT&T WIRELESS GROUP POLICY STATEMENT

  General policy

     Our board of directors has determined that all material matters in which
holders of AT&T common stock and AT&T Wireless Group tracking stock may have
divergent interests will be generally resolved in a manner that is in the best
interests of AT&T and all of its common shareholders after giving fair
consideration to the potentially divergent interests and all other relevant
interests of the holders of the separate classes of AT&T common shares. Under
the AT&T Wireless Group policy statement, the relationship between the AT&T
Common Stock Group and the AT&T Wireless Group and the means by which the terms
of any material transaction between them are determined and governed by a
process of fair dealing.

  Relationship between AT&T Common Stock Group and AT&T Wireless Group

     The AT&T Wireless Group policy statement provides that AT&T is to seek to
manage AT&T Common Stock Group and AT&T Wireless Group in a manner designed to
maximize the operations, unique assets and value of both groups, and with
complementary deployment of capital and facilities. The operating relationship
between the two groups includes the coordination and use of bundled offers,
network services, marketing, sales, branding, and other intellectual property
and technology. AT&T and AT&T Wireless Group use common platforms and technology
across their services where possible. In addition, there are various financial
arrangements between the two groups, including with respect to debt, other
financings and taxes.

                                       96
<PAGE>   103

     General.  The AT&T Wireless Group policy statement provides that, except as
otherwise provided in the AT&T Wireless Group policy statement, all material
commercial transactions between AT&T Common Stock Group and AT&T Wireless Group
are to be on commercially reasonable terms taken as a whole and are subject to
the review and approval of the AT&T Wireless Group capital stock committee.

     Allocation of corporate overhead and support services.  Each group has
access to the support services of the other group, including customer care and
billing platforms.

     For shared corporate services that arise as a result of being part of a
combined entity, including securities filing and financial reporting services,
costs relating to these services are:

     - allocated directly to the group utilizing those services, and

     - if not directly allocable to a group, allocated between the groups on a
       fair and reasonable basis as our board of directors determines.

     For other support services, for example, billing and purchasing services,
the AT&T Wireless Group policy statement provides that the groups are to seek to
achieve enterprise efficiencies to minimize the aggregate costs incurred by the
two groups combined, although each group also will be entitled to negotiate and
procure support services on their own either from the other group or from third
parties.

     Sourcing and provision of other services.  Each group has exclusively
agreed to use the services that the other group offers for use in their
respective packaged, bundled, combined or integrated offerings. This would, for
example, require AT&T Wireless Group to procure long distance services for its
wireless service bundles exclusively from AT&T Common Stock Group and require
AT&T Common Stock Group to procure wireless services for its bundled offerings
exclusively from AT&T Wireless Group. The AT&T Wireless Group policy statement
further provides that each group will provide these services to the other group
at the best price offered by that group to third parties in similar situations
when taking into account all relevant factors, including the availability of
wholesale pricing, volume, peak/off-peak usage and length of commitment. The
establishment of such price should also give consideration to other factors, as
appropriate, such as avoided costs and synergies to be shared between the
groups. In addition, each group cooperates in good faith to develop offers that
reflect such other factors.

     Marketing of services.  The AT&T Wireless Group policy statement provides
that, as a general matter, each group is to design, develop, deploy, produce,
market, sell and service their own service offerings and choose their own sales
channels. In addition, each group is able to negotiate for the use of the sales
channels of the other group to offer their services. With respect to fixed
wireless services, however, it is currently intended that AT&T Wireless Group
will not develop, deploy, produce, market or sell:

     - fixed wireless voice and data services to residences located in AT&T
       Common Stock Group's currently owned and operated broadband service areas
       or after acquired owned and operated broadband service areas in which
       fixed wireless has not begun deployment at the time of acquisition,

     - fixed wireless voice and data services to businesses that are otherwise
       connected by AT&T fiber or broadband, and

     - fixed wireless voice services to residences located in broadband service
       areas served by a cable operator in which AT&T Common Stock Group
       currently has or has contracted for, as of the initial issuance of AT&T
       Wireless Group tracking stock, a substantial equity interest if such
       operator offers AT&T branded residential telephony services within a
       commercially reasonable time, unless prior thereto AT&T Wireless Group
       has received the approval of AT&T's board of directors. Such approval
       will be based on the value and likelihood, considering all terms and
       conditions, of any actual or prospective AT&T branded telephony offers by
       such cable operator.

     Furthermore, AT&T Wireless Group is subject to all existing agreements and
arrangements (including reasonable amendments thereto) entered into by AT&T with
third parties.

     With respect to residences located in the same marketing areas as AT&T's
broadband service areas, AT&T Wireless Group is to, to the extent practical,
conform its voice and data offers to those of AT&T Common Stock Group and AT&T
Common Stock Group will have the non- exclusive right to market AT&T Wireless
Group's fixed wireless services for which it will receive a sales agency fee.
Marketing areas may include those markets in which AT&T has significant cable
licenses and in which geographic proximity, marketing overlap or other factors
support coordinated marketing and sales activities, including development
                                       97
<PAGE>   104

of specific consumer and business service offers. In addition, the policy
statement provides that the groups will work collaboratively with each other to
understand and take into account the other's expansion, acquisition, deployment,
marketing and sales plans, with the goal of minimizing overlaps and conflicts
between the groups.

     When the combined services of the two groups are bundled or offered
together and the total cost to consumers of each of those services are
separately identified on a billing statement, each of AT&T Common Stock Group
and AT&T Wireless Group controls the pricing of its respective services and
receives the associated revenues. The group that sells the service to the public
receives an appropriate fee from the other group for selling the service.

     In a bundled product offering where the services of the two groups are
integrated and the total cost to consumers of each of those services are not
separately identified on a billing statement, the groups work collaboratively to
determine the nature of their arrangements and are also permitted to source the
services of the other group as described above; provided, however, that neither
group may offer a bundle of services comprised primarily of the services of the
other group without that other group's agreement.

     Inter-Group Interest.  The AT&T Wireless Group policy statement provides
that AT&T Wireless Group will not acquire an inter-group interest in AT&T Common
Stock Group.

  Corporate opportunities

     The AT&T Wireless Group policy statement provides that our board of
directors is to allocate any business opportunities and operations, any acquired
assets and businesses and any assumed liabilities between the two groups, in
whole or in part, as it considers to be in the best interests of AT&T and its
shareholders as a whole and as contemplated by the other provisions of the AT&T
Wireless Group policy statement. If a business opportunity or operation, an
acquired asset or business, or an assumed liability would be suitable to be
undertaken by or allocated to either group, our board of directors is to
allocate it using its business judgment or in accordance with procedures that
our board of directors adopts from time to time to ensure that decisions will be
made in the best interests of AT&T and its shareholders as a whole. Any
allocation of this type may involve the consideration of a number of factors
that our board of directors determines to be relevant, including, without
limitation, whether the business opportunity or operation, the acquired asset or
business, or the assumed liability is principally within the existing scope of a
group's business and whether a group is better positioned to undertake or have
allocated to it such business opportunity or operation, acquired asset or
business or assumed liability. Our board of directors currently intends,
however, subject to and without limiting these provisions, and subject to
pre-existing agreements relating to international markets, to allocate future
mobile and fixed wireless opportunities to AT&T Wireless Group.

     Except under the AT&T Wireless Group policy statement and any other
policies adopted by our board of directors, which policies will be designed to
minimize conflicts between the groups, harmonize capital spending and promote
the use by each group of services of the other group, neither AT&T Wireless
Group nor AT&T Common Stock Group has any duty, responsibility or obligation to
refrain from:

     - engaging in the same or similar activities or lines of business as any
       member of the other group,

     - doing business with any potential or actual supplier, competitor or
       customer of any member of any other group, or

     - engaging in, or refraining from, any other activities whatsoever relating
       to any of the potential or actual suppliers or customers of any member of
       the other group.

     In addition, except under the policy statement and any other policies
adopted by our board of directors, neither AT&T Wireless Group nor AT&T Common
Stock Group has any duty, responsibility or obligation:

     - to communicate or offer any business or other corporate opportunity to
       any other person, including any business or other corporate opportunity
       that may arise that more than one group may be financially able to
       undertake, and that are, from their nature, in the line of more than one
       group's business and are of practical advantage to more than one group,

     - to provide financial support to another group, or any member of that
       group, except as described under "-- Relationship with AT&T -- Financing
       arrangements," or

     - otherwise to assist any other group.

     Under no circumstances are any members of AT&T Wireless Group or AT&T
Common Stock Group prevented from entering into written agreements with another
group to define or restrict any aspect of the relationship between the groups.

  Dividend policy

     The AT&T Wireless Group policy statement provides that, subject to the
limitations on dividends set forth in our charter, including any preferential
rights of any series of preferred stock of AT&T, and to the limitations of
applicable law, holders of shares of AT&T Wireless Group tracking stock are
entitled to receive dividends on AT&T Wireless Group tracking stock when, as and
if AT&T's board of directors authorizes and declares dividends on AT&T Wireless
Group tracking stock.

     Since AT&T Wireless Group is expected to require significant capital
commitments to finance its operations and fund its future growth, the AT&T
Wireless Group policy statement provides that AT&T does not expect to pay any
dividends on shares of AT&T Wireless Group tracking stock. If and when our board
of directors determines to pay any dividends on shares of AT&T Wireless Group
tracking stock, the policy statement provides that this determination will be a
business decision that our board of directors makes from time to time based upon
the results of operations, financial condition and capital requirements of AT&T
and other factors that our board of directors considers relevant. Payment of
dividends on AT&T Wireless Group tracking stock also may be restricted by loan
agreements, indentures and other transactions that AT&T enters into from time to
time.

  Financial reporting

     The AT&T Wireless Group policy statement provides that AT&T is to prepare
and include in its filings with the SEC financial statements of AT&T and AT&T
Wireless Group for so long as AT&T Wireless Group tracking stock is outstanding.

  AT&T Wireless Group capital stock committee

     AT&T's by-laws provide for the AT&T Wireless Group capital stock committee
of AT&T's board of directors that we describe under "-- AT&T Wireless Group
Capital Stock Committee."

     In making determinations in connection with the policies set forth in the
AT&T Wireless Group policy statement, the members of AT&T's board of directors
and the AT&T Wireless Group capital stock committee act in a fiduciary capacity
and in accordance with legal guidance concerning their respective obligations
under applicable law. The delegation of responsibilities to the AT&T Wireless
Group capital stock committee is subject to changes our board of directors may
determine.

  Amendment and modification to the AT&T Wireless Group policy statement

     AT&T's board of directors may modify, suspend or rescind the policies set
forth in the AT&T Wireless Group policy statement, including any resolution
implementing the provisions of the policy statement. AT&T's board may also adopt
additional or other policies or make exceptions with respect to the application
of the policies described in the AT&T Wireless Group policy statement in
connection with particular facts and circumstances, all as our board may
determine, consistent with its fiduciary duties to AT&T and all of our
shareholders.

RELATIONSHIP WITH AT&T PRIOR TO THE SPIN-OFF

  Branding

     AT&T Wireless Group is permitted, on the same discretionary basis as other
businesses that AT&T wholly owns, or substantially owns in excess of a majority
of the economic interest in, to operate under the AT&T service mark for
appropriate business activities in its capacity as a division or subsidiary of
AT&T. There are no royalty or licensing fees related to the use of branding.
AT&T's divisions' or subsidiaries' use of the brand is limited in certain
respects, including requiring compliance with AT&T's corporate brand strategy,
policies, graphics standards, advertising policies, quality control and
restrictions on certain activities relating to the brand, including a
prohibition on licensing and sublicensing without corporate approval.

                                       99
<PAGE>   106

  Intellectual Property

     Intellectual property is to be managed by the group that has managed it
historically. AT&T Common Stock Group and AT&T Wireless Group, on the same basis
they have enjoyed historically, have the right to use the intellectual property
managed by the other group, or with respect to which either has the power to
grant such rights, for appropriate business activities. The groups also
collaborate to achieve enterprise objectives with respect to the licensing or
sale of intellectual property to third parties. The policy of the AT&T Wireless
Group capital stock committee is not to sell or license any intellectual
property that is predominantly used by AT&T Wireless Group if that sale of
license would result in a material competitive disadvantage to AT&T Wireless
Group. Any fees obtained through such sales or licensing are allocated to the
group that predominantly uses the intellectual property sold or licensed, or if
no specific intellectual property can be associated with a fee or such
intellectual property is not predominantly used by any one group, then allocated
using the same general allocation as overhead expenses.

  Commercial transactions between groups

     All commercial transactions between AT&T Common Stock Group and AT&T
Wireless Group are intended to be on commercially reasonable terms taken as a
whole. The groups have negotiated and developed their arrangements over time and
these arrangements have been subject to the review and approval of the AT&T
Wireless Group capital stock committee.

     In the future, we may reallocate assets between AT&T Common Stock Group and
AT&T Wireless Group in exchange for an increase or decrease in the retained
inter-group interest held by AT&T Common Stock Group in AT&T Wireless Group. Any
reallocations of assets between the groups that do not result in such an
adjustment, other than reallocations made under a contract for the provision of
goods or services between the groups, will be accompanied by:

     - the reallocation by the transferee group to the transferor group of other
       assets or consideration,

     - the creation of inter-group debt owed by the transferee group to the
       transferor group, or

     - the reduction of inter-group debt owed by the transferor group to the
       transferee group,

     - in each case, in an amount having a fair market value, in the judgment of
       our board of directors, equivalent to the fair market value of the assets
       reallocated by the transferor group.

  Financing arrangements

     Loans from AT&T or any member of AT&T Common Stock Group to any member of
AT&T Wireless Group are to be made at interest rates, fees and on other terms
and conditions designed to be substantially equivalent to the interest rates,
fees and other terms and conditions that AT&T Wireless Group would be able to
obtain from third parties, including the public markets, as a non-affiliate of
AT&T without the benefit of any guaranty by AT&T or any member of AT&T Common
Stock Group. This policy contemplates that these loans are to be made on the
basis set forth above regardless of the interest rates and other terms and
conditions on which AT&T or members of AT&T Common Stock Group may have acquired
the funds. If, however, AT&T incurs any fees or charges in order to keep
available funds for use by AT&T Wireless Group, those fees or charges are to be
allocated to AT&T Wireless Group.

     A corporate entity within AT&T Wireless Group has issued to AT&T $3.0
billion of 9% cumulative preferred stock that, subject to the approval of AT&T
Wireless Group capital stock committee, is redeemable at the option of AT&T.
This preferred stock is held by AT&T on behalf of AT&T Common Stock Group. AT&T
Common Stock Group also had $1.8 billion of AT&T Wireless Group indebtedness at
September 30, 2000.

  Accounting matters

     AT&T prepares financial statements in accordance with generally accepted
accounting principles, consistently applied, for AT&T Wireless Group, and pro
forma financial information for AT&T and AT&T Wireless Group, as well as full
consolidated financial statements of AT&T. The financial statements and
information for each of the groups principally reflect the financial position,
results of operations and cash flows

                                       100
<PAGE>   107

of the businesses included in those groups. Notwithstanding any allocation of
assets or liabilities for dividend purposes or the purpose of preparing group
financial statements, holders of AT&T common stock and holders of AT&T Wireless
Group tracking stock are subject to risks associated with an investment in a
single corporation and all of AT&T's businesses, assets and liabilities.

  Tax sharing agreement

     AT&T Common Stock Group and AT&T Wireless Group have entered into a tax
sharing agreement dated as of May 2, 2000, that provides for tax sharing
payments between AT&T Common Stock Group and AT&T Wireless Group based on the
taxes or tax benefits of a hypothetical affiliated group consisting of AT&T
Common Stock Group and AT&T Wireless Group with respect to taxable periods
ending after the issuance of the shares of AT&T Wireless Group tracking stock.
This hypothetical group does not include Liberty Media Group. A separate tax
sharing agreement exists between AT&T Common Stock Group and the Liberty Media
Group under which tax sharing payments are made between AT&T and Liberty Media
Group to the extent that the taxes of the actual affiliated group of which AT&T
is the common parent are increased or decreased as a result of the inclusion of
the Liberty Media Group in that affiliated group.

     Under the tax sharing agreement between AT&T Common Stock Group and AT&T
Wireless Group, the consolidated tax liability before credits of the
hypothetical group consisting of AT&T Common Stock Group and AT&T Wireless Group
is allocated between AT&T Common Stock Group and the AT&T Wireless Group based
on each group's contribution to consolidated taxable income of the hypothetical
group. Such allocation takes into account losses, deductions and other tax
attributes, such as capital losses or charitable deductions, that are utilized
by the hypothetical group even if these attributes could not be utilized on a
stand-alone basis. For purposes of the tax sharing agreement, the $3.0 billion
of 9% cumulative preferred stock issued by a corporate entity within AT&T
Wireless Group to AT&T, and $1.8 billion of AT&T Wireless Group indebtedness
held by AT&T Common Stock Group are treated as intercompany debt instruments,
each with an issue price equal to its face amount, for federal, state and local
income tax purposes. Accordingly, tax sharing payments are calculated by
treating coupon payments on the preferred stock and debt as interest expense to
AT&T Wireless Group and interest income to AT&T Common Stock Group. Tax sharing
payments in respect of the consolidated tax liability of the hypothetical group,
after allocation of consolidated tax credits, are made between AT&T Common Stock
Group and AT&T Wireless Group consistent with the allocations under the tax
sharing agreement.

     In addition, under the tax sharing agreement, AT&T Wireless Group is
responsible for all tax items resulting from the attribution to AT&T Wireless
Group, or transfer to a legal entity which is a member of AT&T Wireless Group,
of certain international wireless investments formerly owned by MediaOne as well
as any tax items resulting from the distribution of the stock of any company the
assets of which are tracked by AT&T Wireless Group tracking stock.

     The tax sharing payments under the tax sharing agreement assume that the
members of AT&T Common Stock Group and AT&T Wireless Group are members of the
same affiliated, consolidated, combined or unitary group for the relevant
federal, state, local or foreign income tax purposes with respect to taxable
periods ending after the issuance of the shares of AT&T Wireless Group tracking
stock. It is possible, however, that the IRS may assert that AT&T Wireless Group
tracking stock is not stock of AT&T, in which case the members of AT&T Common
Stock Group and AT&T Wireless Group may not be members of the same federal
income tax affiliated group filing consolidated returns. AT&T believes that it
is unlikely that the IRS would prevail on that view, but no assurance can be
given in that regard. AT&T Wireless Group would be responsible under the tax
sharing agreement for any corporate-level taxes resulting from the treatment of
AT&T Wireless Group tracking stock as not stock of AT&T, and any corporate-level
taxes on the actual or deemed disposition of AT&T Wireless Group caused by the
issuance of AT&T Wireless Group tracking stock.

AT&T PREFERRED STOCK

     AT&T preferred stock may be issued from time to time in one or more series.
All shares of AT&T preferred stock of all series will rank equally and be
identical in all respects, except that our board of directors is authorized to
fix the number of shares in each series, the designation thereof, and, subject
to the provisions of Article Third of AT&T's charter, the relative rights,
preferences and limitations of each series and the variations in such rights,
preferences and limitations as between series and specifically is authorized to
fix with respect to each series:

     - the dividend rate on the shares of such series and the date or dates from
       which dividends will be cumulative; the times when, the prices at which,
       and all other terms and conditions upon which, shares of such series will
       be redeemable,

     - the amounts that the holders of shares of such series will be entitled to
       receive upon the liquidation, dissolution or winding up of AT&T, which
       amounts may vary depending on whether such liquidation, dissolution or
       winding up is voluntary or involuntary and, if voluntary, may vary at
       different dates,

     - whether or not the shares of such series will be subject to the operation
       of a purchase, retirement or sinking fund and, if so, the extent to and
       manner in which such purchase, retirement or sinking fund will be applied
       to the purchase or redemption of the shares of such series for retirement
       or for other corporate purposes and the terms and provisions relative to
       the operation of the said fund or funds,

     - whether or not the shares of such series will be convertible into or
       exchangeable for shares of any other class or series or for any class of
       common shares and, if so, the price or prices or the rate or rates of
       conversion or exchange and the method, if any, of adjusting the same,

     - the restrictions, if any, upon the payment of dividends or making of
       other distributions on, and upon the purchase or other acquisition of,
       common shares,

     - the restrictions, if any, upon the creation of indebtedness, and the
       restrictions, if any, upon the issue of any additional shares ranking on
       a parity with or prior to the shares of such series in addition to the
       restrictions provided for in Article Third of AT&T's charter,

     - the voting powers, if any, of the shares of such series in addition to
       the voting powers provided for in Article Third of AT&T's charter, and

     - such other rights, preferences and limitations as will not be
       inconsistent with Article Third of AT&T's charter.

                                       102
<PAGE>   109

     All shares of any particular series will rank equally and be identical in
all respects, except that shares of any one series issued at different times may
differ as to the date from which dividends will be cumulative.

     Dividends on shares of AT&T preferred stock of each series will be
cumulative from the date or dates fixed with respect to such series, and will be
paid or declared or set apart for payment for all past dividend periods and for
the current dividend period before any dividends (other than dividends payable
in common shares) will be declared or paid or set apart for payment on common
shares. Whenever, at any time, full cumulative dividends for all past dividend
periods and for the current dividend period will have been paid or declared and
set apart for payment on all then-outstanding shares of AT&T preferred stock and
all requirements with respect to any purchase, retirement or sinking fund or
funds for all series of AT&T preferred stock will have been complied with, our
board of directors may declare dividends on the common shares and the shares of
AT&T preferred stock will not be entitled to share therein.

     Upon any liquidation, dissolution or winding up of AT&T, the holders of
shares of AT&T preferred stock of such series will be entitled to receive the
amounts to which such holders are entitled as fixed with respect to such series,
including all dividends accumulated to the date of final distribution, before
any payment or distribution of assets of AT&T will be made to or set apart for
the holders of common shares and, after such payments will have been made in
full to the holders of shares of AT&T preferred A stock, the holders of common
shares will be entitled to receive any and all assets remaining to be paid or
distributed to shareholders and the holders of shares of AT&T preferred stock
will not be entitled to share therein. For the purposes of this paragraph, the
voluntary sale, conveyance, lease, exchange or transfer of all or substantially
all the property or assets of AT&T or a consolidation or merger of AT&T with one
or more other corporations (whether or not AT&T is the surviving corporation of
such consolidation or merger) will not be deemed to be a liquidation,
dissolution or winding up, voluntary or involuntary.

     The aggregate amount that all shares of AT&T preferred stock outstanding at
any time will be entitled to receive on involuntary liquidation, dissolution or
winding up will not exceed $8 billion.

     So long as any shares of AT&T preferred stock are outstanding, AT&T will
not:

     - authorize shares of stock ranking prior to shares of AT&T preferred stock
       or change any provision of Article Third of AT&T's charter so to affect
       adversely shares of AT&T preferred stock without the affirmative vote or
       consent of the holders of at least 66 2/3% of all the shares of AT&T
       preferred stock at the time outstanding;

     - change any of the provisions of any series of AT&T preferred stock at the
       time outstanding so as to affect adversely shares of such series without
       the affirmative vote or consent of the holders of at least 66 2/3% of
       such series of AT&T preferred stock; or

     - increase the authorized number of shares of AT&T preferred stock or
       increase the authorized number of shares of any class of stock ranking on
       a parity with the AT&T preferred stock without the affirmative vote or
       consent of the holders of at least a majority of all the shares of AT&T
       preferred stock at the time outstanding.

     Whenever, at any time or times, dividends payable on shares of AT&T
preferred stock will be in default in an aggregate amount equivalent to six full
quarterly dividends on any series of AT&T preferred stock at the time
outstanding, the number of directors then constituting our board of directors
will be increased by two, and the outstanding shares of AT&T preferred stock
will, in addition to any other voting rights, have the exclusive right, voting
separately as a class and without regard to series, to elect two directors of
AT&T to fill such newly created directorships, and such right will continue
until such time as all dividends accumulated on all shares of AT&T preferred
stock to the latest dividend payment date will have been paid or declared and
set apart for payment.

     No holder of shares of AT&T preferred stock of any series, irrespective of
any voting or other right of shares of such series, will have, as such holder,
any preemptive right to purchase any other shares of AT&T or any securities
convertible into or entitling the holder to purchase such other shares.

                                       103
<PAGE>   110

     If, in any case, the amounts payable with respect to any requirements to
retire shares of AT&T preferred stock are not paid in full in the case of all
series with respect to which such requirements exist, the number of shares to be
retired in each series will be in proportion to the respective amounts that
would be payable on account of such requirements if all amounts payable were
paid in full.

     DoCoMo will purchase 812,511.778 shares of a new class of AT&T preferred
stock, par value $1.00, that we call "New Wireless tracking stock." Each share
of New Wireless tracking stock is intended to be the economic and voting
equivalent of 500 shares of AT&T Wireless Group tracking stock, and is
convertible at any time into 500 shares of AT&T Wireless Group tracking stock.
The New Wireless tracking stock also has some additional rights not available to
holders of AT&T Wireless Group tracking stock. See "Recent
Developments -- DoCoMo Strategic Investment -- New Class of AT&T Wireless Group
Tracking Stock."

AT&T WIRELESS GROUP TRACKING STOCK

  AT&T Wireless Group

     We designed AT&T Wireless Group tracking stock to track the economic
performance of AT&T Wireless Group. "AT&T Wireless Group" consists of,
generally, the interest of AT&T or any of its subsidiaries in all of the
businesses, assets and liabilities reflected in the audited combined financial
statements of AT&T Wireless Group, as of December 31, 1999, including any
successor to AT&T Wireless Group by merger, consolidation or sale of all or
substantially all of its assets. AT&T's charter contains adjustments to the
definition of AT&T Wireless Group to reflect, among other things, related assets
and liabilities (including contingent liabilities), net income and net losses
arising after the date of such financial statements, contributions and
allocations of assets, liabilities and businesses between the groups and
acquisitions and dispositions.

     The "AT&T Common Stock Group" consists of, generally, the interest of AT&T
or any of its affiliates in all of the businesses in which AT&T or any of its
affiliates (or any of their predecessors or successors) is or has been engaged,
directly or indirectly, and the respective assets and liabilities of AT&T or any
of its affiliates, other than:

     - the economic interest in AT&T Wireless Group represented by the
       outstanding shares of AT&T Wireless Group tracking stock, and

     - any businesses, assets or liabilities of the Liberty Media Group.

     We created the Liberty Media Group at the time of the TCI merger and
defined it to consist primarily of TCI's programming assets and businesses,
TCI's principal international assets and businesses, and substantially all of
TCI's non-cable and non-programming assets and businesses other than its
interest in At Home Corporation.

  AT&T Wireless Group Allocation Fraction

     AT&T's charter defines the "AT&T Wireless Allocation Fraction" to represent
the interest in the economic performance of AT&T Wireless Group reflected by
AT&T Wireless Group tracking stock issued to the public. At any time that all of
the interest in the economic performance of AT&T Wireless Group is not reflected
by the outstanding AT&T Wireless Group tracking stock, this fraction will be
used, in effect, to allocate to the AT&T Common Stock Group the right to
participate in any dividend, distribution or liquidation payment made to holders
of AT&T Wireless Group tracking stock. This right to participate will reflect
the inter-group interest of the AT&T Common Stock Group in AT&T Wireless Group,
which will be equal to one minus this fraction. At any time that all of the
interest in the economic performance of AT&T Wireless Group is fully reflected
by the outstanding AT&T Wireless Group tracking stock, this fraction will equal
one and, accordingly, the inter-group interest will equal zero.

                                       104
<PAGE>   111

     Subject to the criteria we describe below, this fraction is subject to
adjustment from time to time as our board of directors deems appropriate:

     - to reflect subdivisions (by stock split or otherwise) and combinations
       (by reverse stock split or otherwise) of AT&T Wireless Group tracking
       stock and stock dividends payable in shares of AT&T Wireless Group
       tracking stock,

     - to reflect the fair market value of contributions or allocations by AT&T
       of cash, property or other assets or liabilities from the AT&T Common
       Stock Group to AT&T Wireless Group (or vice versa), or of cash or
       property or other assets or liabilities of the AT&T Common Stock Group
       to, or for the benefit of, employees of AT&T Wireless Group in connection
       with employee benefit plans or arrangements of AT&T or any of its
       subsidiaries (or vice versa),

     - to reflect the number of shares of capital stock of AT&T contributed to,
       or for the benefit of, employees of AT&T Wireless Group in connection
       with benefit plans or arrangements of AT&T or any of its subsidiaries,

     - to reflect repurchases by AT&T of shares of AT&T Wireless Group tracking
       stock for the account of AT&T Wireless Group,

     - to reflect issuances of AT&T Wireless Group tracking stock for the
       account of AT&T Wireless Group,

     - to reflect dividends or other distributions to holders of AT&T Wireless
       Group tracking stock, to the extent no payment is made to the AT&T Common
       Stock Group, and

     - under such other circumstances as our board of directors determines
       appropriate to reflect the economic substance of any other event or
       circumstance.

     In addition, in determining the percentage interest of holders of AT&T
Wireless Group tracking stock in any particular dividend or other distribution,
we will reduce the economic interest of holders of AT&T Wireless Group tracking
stock to reflect dilution arising from shares of AT&T Wireless Group tracking
stock reserved for issuance upon conversion, exercise or exchange of other
securities that are entitled to participate in such dividend or other
distribution.

     AT&T's charter provides that any such adjustment must be made in a manner
that our board of directors determines to be fair and equitable to holders of
AT&T common stock and AT&T Wireless Group tracking stock. In the event that any
assets or other property are acquired by the AT&T Common Stock Group and
allocated or contributed to AT&T Wireless Group, the consideration paid by the
AT&T Common Stock Group to acquire such assets or other property will be
presumed to be its "fair market value" as of its acquisition. Any adjustment to
AT&T Wireless Group Allocation Fraction made by our board of directors in
accordance with these principles will be at the sole discretion of our board of
directors and will be final and binding on all shareholders.

  Voting Rights

     Each outstanding share of AT&T Wireless Group tracking stock has one-half
of a vote per share. The voting rights of AT&T Wireless Group tracking stock
will be subject to adjustments to reflect stock splits, reverse stock splits,
stock dividends or certain stock distributions with respect to AT&T common
stock, AT&T Wireless Group tracking stock or Liberty Media Group tracking stock.

     Holders of AT&T common stock are entitled to one vote on all matters voted
on by shareholders. Holders of Class B Liberty Media Group tracking stock are
entitled to 0.375 of a vote per share and holders of Class A Liberty Media Group
tracking stock have 0.0375 of a vote per share on all matters voted on by
shareholders. The voting rights of AT&T common stock, Class B Liberty Media
Group tracking stock and Class A Liberty Media Group tracking stock will be
subject to adjustments to reflect stock splits, reverse stock splits, stock
dividends or certain stock distributions with respect to AT&T common stock, AT&T
Wireless Group tracking stock or Liberty Media Group tracking stock, including
any distribution of AT&T Wireless Group tracking stock to holders of AT&T common
stock.

     Except as otherwise required by New York law or any special voting rights
of any class or series of AT&T preferred stock, Liberty Media Group tracking
stock or any other class of AT&T common shares, holders of shares of AT&T common
stock, AT&T Wireless Group tracking stock, each other class of common shares, if
any, that is entitled to vote, Class A Liberty Media Group tracking stock and
Class B Liberty Media Group tracking stock, and holders of shares of each class
or series of AT&T preferred stock, if any, that is entitled to vote, will vote
as one class with respect to all matters to be voted on by shareholders of AT&T.

     No separate class vote of AT&T Wireless Group tracking stock will be
required, except as required by the NYBCL.

  Dividends

     General.  Provided that AT&T has sufficient assets to pay a dividend under
applicable law, after excluding the available dividend amount relating to the
Liberty Media Group, dividends on AT&T Wireless Group tracking stock are limited
to an available dividend amount that is designed to be equivalent to the amount
that would legally be available for dividends on that stock if AT&T Wireless
Group were a stand-alone corporation. Dividends on AT&T common stock are limited
to the amount of legally available funds for all of AT&T less the sum of the
available dividend amount for AT&T Wireless Group tracking stock and the
available dividend amount for Liberty Media Group tracking stock. AT&T does not
expect to pay dividends on shares of AT&T Wireless Group tracking stock.

     Discrimination among classes of common shares.  Our charter does not
provide for mandatory dividends. Provided that there are sufficient assets to
pay a dividend on a class of stock as described under " -- General," our board
of directors will have the sole authority and discretion to declare and pay
dividends (or to refrain from declaring or paying dividends), in equal or
unequal amounts, on AT&T common stock, AT&T Wireless Group tracking stock,
Liberty Media Group tracking stock, any other class of common shares or any two
or more of such classes. Subject to not exceeding the applicable available
dividend amount, our board of directors has this power regardless of the
relative available dividend amounts, prior dividend amounts declared,
liquidation rights or any other factor. Our board of directors has adopted a
policy with respect to Liberty Media Group tracking stock that it will
distribute to the holders of Liberty Media Group tracking stock any dividends it
receives from any entity included in the Liberty Media Group.

  Share Distributions

     Subject to the provisions of Liberty Media Group tracking stock, AT&T may
declare and pay a distribution consisting of shares of AT&T common stock, AT&T
Wireless Group tracking stock or any other securities of AT&T or any other
person to holders of AT&T Wireless Group tracking stock only in accordance with
the provisions described below. We refer to this type of distribution as a
"share distribution."

     Distributions on AT&T common stock or AT&T Wireless Group tracking
stock.  Subject to any limitations imposed by the terms of Liberty Media Group
tracking stock, AT&T may declare and pay a share distribution to holders of AT&T
common stock, AT&T Wireless Group tracking stock or any other class of common
shares consisting of any securities of AT&T, any subsidiary of AT&T, or any
other person. However, securities attributable to a group may be distributed to
holders of another group only for consideration.

     Discrimination among classes of common shares.  AT&T's charter does not
provide for mandatory share distributions. Subject to the restrictions described
above or that are in effect regarding Liberty Media Group tracking stock, our
board of directors will have the sole authority and discretion to declare and
pay share distributions (or to refrain from declaring or paying share
distributions), in equal or unequal amounts, on AT&T common stock, AT&T Wireless
Group tracking stock, Liberty Media Group tracking stock, any other class of
common shares or any two or more of such classes. Subject to not exceeding the
applicable available dividend amounts, our board of directors has this power
regardless of the relative available dividend amounts, prior share distributions
amounts declared, liquidation rights or any other factor.

  Redemption

     Redemption in exchange for shares of AT&T common stock at option of our
board of directors. At any time following either the occurrence of tax-related
events or May 2, 2002, our board of directors, in its sole discretion, may
redeem all outstanding shares of AT&T Wireless Group tracking stock for shares
of AT&T common stock. In such event, each share of AT&T Wireless Group tracking
stock will be redeemed in exchange for that number of shares of AT&T common
stock, calculated to the nearest 1/10,000, equal to 110% of the ratio of the
average market price per share of AT&T Wireless Group tracking stock to the
average market price per share of AT&T common stock.

     In this case, the average market price per share of AT&T common stock or
AT&T Wireless Group tracking stock, as the case may be, means the average of the
daily market value per share for such AT&T common stock or AT&T Wireless Group
tracking stock for the 40 consecutive trading days ending on the 15th trading
day prior to the date notice of the redemption is mailed to holders of AT&T
Wireless Group tracking stock.

     In order to redeem AT&T Wireless Group tracking stock on the basis of a tax
event, AT&T must obtain the opinion of counsel that, as a result of an amendment
to or change (or prospective change) in a law or an interpretation of the law
that takes place after AT&T Wireless Group tracking stock is issued, there is
more than an insubstantial risk that:

     - any issuance of AT&T Wireless Group tracking stock would be treated as a
       sale or other taxable disposition by AT&T or any of its subsidiaries of
       any of the assets, operations or relevant subsidiaries underlying AT&T
       Wireless Group tracking stock,

     - the existence of AT&T Wireless Group tracking stock would subject AT&T,
       its subsidiaries or its affiliates, or any of their respective successors
       to the imposition of tax or other adverse tax consequences, or

     - either AT&T common stock or AT&T Wireless Group tracking stock would not
       be treated solely as common stock of AT&T.

     Redemption in exchange for stock of qualifying subsidiaries at option of
our board of directors. AT&T's charter also provides that AT&T may, at any time,
redeem all outstanding shares of AT&T Wireless Group tracking stock in exchange
for a specified number of outstanding shares of common stock of a subsidiary of
AT&T that satisfies certain requirements under the Internal Revenue Code and
that holds all of the assets and liabilities of AT&T Wireless Group. We refer to
a subsidiary that satisfies these requirements as a "qualifying subsidiary."
This type of redemption may only be made on a pro rata basis, and must be tax
free to the holders of AT&T Wireless Group tracking stock, except with respect
to any cash that holders receive in lieu of fractional shares.

     In this case, we would exchange each share of AT&T Wireless Group tracking
stock, on a pro rata basis, for an aggregate number of shares of common stock of
the qualifying subsidiary equal to the number of outstanding shares of common
stock of the qualifying subsidiary held by AT&T.

     Redemption in connection with certain significant transactions. In the
event of a sale, transfer, assignment or other disposition by AT&T in a
transaction or series of related transactions, of all or substantially all of
the properties and assets of AT&T Wireless Group, AT&T is generally required to
take one of the following actions, which will be selected in the sole discretion
of our board of directors:

     - AT&T may redeem each outstanding share of AT&T Wireless Group tracking
       stock in exchange for a number of shares of AT&T common stock (calculated
       to the nearest 1/10,000) equal to 110% of the ratio of the average market
       price per share of AT&T Wireless Group tracking stock to the average
       market price per share of AT&T common stock. For this purpose, the
       "average market price per share" of AT&T common stock or AT&T Wireless
       Group tracking stock, as the case may be, means the average of the daily
       market value per share for such AT&T common stock or AT&T Wireless Group
       tracking stock during the 10-trading day period beginning on the 15th
       trading day following completion of that transaction.
                                       107
<PAGE>   114

     - Subject to limitations, AT&T may declare and pay a dividend in cash
       and/or in securities (other than AT&T common stock) or other property to
       holders of the outstanding shares of AT&T Wireless Group tracking stock
       equally on a share-for-share basis in an aggregate amount equal to the
       net proceeds of the disposition allocable to AT&T Wireless Group tracking
       stock.

     - Subject to limitations, if the disposition involves the disposition of
       all, not merely substantially all, of the properties and assets of AT&T
       Wireless Group, AT&T may redeem all outstanding shares of AT&T Wireless
       Group tracking stock in exchange for cash and/or securities or other
       property in an aggregate amount equal to the net proceeds of such
       disposition allocable to AT&T Wireless Group tracking stock.

     - Subject to limitations, if the disposition involves substantially all,
       but not all, of the properties and assets of AT&T Wireless Group, AT&T
       may redeem a number of outstanding shares of AT&T Wireless Group tracking
       stock in exchange for a redemption price equal to the net proceeds of
       that disposition. The number of shares of AT&T Wireless Group tracking
       stock to be redeemed would be equal to the lesser of (1) a number
       determined by dividing the aggregate amount allocated to the redemption
       of these shares by the average market value of one share of AT&T Wireless
       Group tracking stock during the 10-trading day period beginning on the
       15th trading day following the completion of that disposition and (2) the
       total number of outstanding shares of AT&T Wireless Group tracking stock.

     - Subject to limitations, AT&T may take a combination of the actions
       described in the preceding bullets whereby AT&T may redeem some shares of
       AT&T Wireless Group tracking stock in exchange for shares of AT&T common
       stock at the exchange rate described in the first bullet above, and use
       an amount equal to a portion of the net proceeds of the disposition
       allocable to AT&T Wireless Group tracking stock to either (1) declare and
       pay a dividend as described in the second bullet above, or (2) redeem
       part or all of the remaining shares of AT&T Wireless Group tracking stock
       as described in the third or fourth bullet above.

     For purposes of these provisions, "substantially all of the properties and
assets" of AT&T Wireless Group as of any date means a portion of such properties
and assets that represents at least 80% of the fair value of the properties and
assets attributed to AT&T Wireless Group as of such date.

     Certain exceptions.  The provisions described under "-- Redemption in
connection with certain significant transactions" will not apply, and AT&T will
not be required to redeem any securities or make any dividend or other
distribution it would otherwise be required to make, in some circumstances,
including the following:

     - if the underlying disposition is conditioned upon the affirmative vote of
       a majority of holders of AT&T Wireless Group tracking stock, voting as a
       separate class,

     - if the disposition is in connection with a liquidation of AT&T,

     - if the disposition is to a person or group of which AT&T is the majority
       owner and AT&T Wireless Group receives in exchange primarily equity
       securities of that person or group as consideration,

     - in connection with a spin-off or similar distribution of AT&T's entire
       interest in AT&T Wireless Group to the holders of AT&T Wireless Group
       tracking stock, including a distribution that is made in connection with
       a mandatory redemption as described under "-- Redemption in exchange for
       shares of AT&T common stock at option of our board of directors" or
       "-- Redemption in exchange for stock of qualifying subsidiaries at option
       of our board of directors," and

     - in connection with a "related business transaction," which generally
       means a disposition of all or substantially all of the assets attributed
       to AT&T Wireless Group in which AT&T receives equity securities of an
       entity that engages or proposes to engage primarily in one or more
       businesses similar or complementary to the businesses conducted by AT&T
       Wireless Group prior to such transaction.

  General Procedures

     Public announcements; notices.  In the case of specified dispositions or a
redemption, AT&T will publicly announce or otherwise provide specified
information to holders of AT&T Wireless Group tracking stock.

     Fractional shares.  Our board of directors will not have to issue or
deliver any fractional shares to any holder of AT&T Wireless Group tracking
stock upon any redemption, dividend or other distribution under the provisions
described under "-- Redemption." Instead of issuing fractional shares, AT&T will
pay cash for the fractional share in an amount equal to the fair market value of
the fractional share, without interest.

     No adjustments for dividends or other distributions. No adjustments for
dividends will be made upon the exchange of any shares of AT&T Wireless Group
tracking stock; except that, if a redemption date with respect to AT&T Wireless
Group tracking stock comes after the record date for the payment of a dividend
or other distribution to be paid on that stock but before the payment or
distribution, the registered holders of those shares at the close of business on
such record date will be entitled to receive the dividend or other distribution
on the payment date, notwithstanding the redemption of those shares or AT&T's
default in payment of the dividend or distribution.

     Payment of taxes.  If any person exchanging a certificate representing
shares of AT&T Wireless Group tracking stock wants us to issue a certificate in
a different name than the registered name on the old certificate, that person
must pay any transfer or other taxes required by reason of the issuance of the
certificate in another name or establish, to the satisfaction of AT&T or its
agent, that the tax has been paid or is not applicable.

  Liquidation Rights

     In the event of a liquidation, dissolution or winding up of AT&T, whether
voluntary or involuntary, AT&T will first pay or provide for payment of debts
and other liabilities of AT&T, including the liquidation preferences of any
class or series of AT&T preferred stock. Thereafter, holders of the shares of
AT&T common stock, Liberty Media Group tracking stock, AT&T Wireless Group
tracking stock and any other class of AT&T common shares will share in the funds
of AT&T remaining for distribution to its common shareholders in proportion to
the aggregate market capitalization of the outstanding shares of each class of
stock, as applicable, to the aggregate market capitalization of all the classes
of AT&T common stock. AT&T will calculate the market capitalizations based on
the 20-trading day period ending on the trading day prior to the date of the
public announcement of the liquidation, dissolution or winding up of AT&T.

     None of the following, by itself, will constitute a liquidation,
dissolution or winding up of AT&T:

     - the consolidation or merger of AT&T with or into any other corporation or
       corporations or the sale, transfer or lease of all or substantially all
       of the assets of AT&T,

     - any transaction or series of related transactions that results in all of
       the assets and liabilities included in AT&T Wireless Group being held by
       one or more AT&T Wireless Group subsidiaries and the distribution of such
       AT&T Wireless Group subsidiaries, and no other material assets or
       liabilities, to the holders of the outstanding AT&T Wireless Group
       tracking stock, and

     - any transaction or series of related transactions that results in all of
       the assets and liabilities included in the Liberty Media Group being held
       by one or more Liberty Media Group subsidiaries and the distribution of
       such Liberty Media Group subsidiaries, and no other material assets or
       liabilities, to the holders of the outstanding Liberty Media Group
       tracking stock (but this will be subject to the provisions relating to
       the redemption of shares of Liberty Media Group tracking stock described
       in our charter).

  Determinations by Our Board of Directors

     Any determinations made by our board of directors under any provision
described in AT&T's charter will be final and binding on all shareholders of
AT&T, except as may otherwise be required by law. AT&T will prepare a statement
of any determination by our board of directors respecting the fair market value
of any properties, assets or securities, and will file the statement with our
Corporate Secretary.

ANTI-TAKEOVER CONSIDERATIONS

     The New York Business Corporation Law, AT&T's charter and the AT&T by-laws
contain provisions which could serve to discourage or make more difficult a
change in control of AT&T without the support of the AT&T board of directors or
without meeting various other conditions.

  Business Combinations

     Under the NYBCL, a plan of merger or consolidation, a plan of share
exchange or the sale, lease, exchange or other disposition of all or
substantially all of the assets of a corporation is required to be approved in
the case of corporations like AT&T that were in existence on February 22, 1998
and that do not expressly provide in their certificates of incorporation for
majority approval of such transactions, by two-thirds of the votes of all
outstanding shares entitled to vote thereon. AT&T's charter does not contain a
provision expressly providing for majority approval of such transactions.

  State Takeover Legislation

     Section 912 of the NYBCL prohibits any business combination (defined to
include a variety of transactions, including mergers, sales or dispositions of
assets, issuances of stock, liquidations, reclassifications and benefits from
the corporation, including loans or guarantees) with, involving or proposed by
any interested shareholder (defined generally as any person who, directly or
indirectly, beneficially owns 20% or more of the outstanding voting stock of a
New York corporation) for a period of five years after the date on which the
interested shareholder became an interested shareholder. After such five-year
period, a business combination between a New York corporation and such
interested shareholder is prohibited unless either certain "fair price"
provision are complied with or the business combination is approved by a
majority of the outstanding voting stock not beneficially owned by such
interested shareholder or its affiliates and associates. The restrictions of the
NYBCL do not apply, however, to any business combination with an interested
shareholder if such business combination, or the purchase of stock by the
interested shareholder that cause such shareholder to become an interested
shareholder, was approved by the board of directors of the New York corporation
prior to the date on which the interested shareholder became an interested
shareholder.

     A New York corporation may adopt an amendment to its by-laws, approved by
the affirmative vote of a majority of votes of the outstanding voting stock,
excluding the voting stock of interested shareholders and their affiliates and
associates, expressly electing not to be governed by Section 912 of the NYBCL.
Such amendment will not, however, be effective until 18 months after such
shareholder vote and will not apply to any business combination with an
interested shareholder who was such on or prior to the effective date of such
amendment. The AT&T by-laws contain no provision electing not to be governed by
such section of the NYBCL.

  Shareholder Action

     Under the NYBCL, any action required or permitted to be taken by a vote at
a meeting of shareholders may be taken without a meeting by written consent,
setting forth the action so taken, signed by the holders of all outstanding
shares entitled to vote thereon or, if the certificate of incorporation so
permits, signed by holders of outstanding shares having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted. AT&T's charter does not contain such a provision.

  Shareholder Proposals

     The AT&T by-laws require that, for business to be properly brought before
an annual meeting by a shareholder, or for shareholder nominations to be made at
an annual meeting, the shareholder must have delivered notice thereof to AT&T
(containing certain information specified in the AT&T by-laws) not less than 90
nor more than 120 days prior to the first anniversary of the preceding year's
annual meeting.

                                       110
<PAGE>   117

  Meetings of Shareholders

     The AT&T by-laws provide that special meetings of the shareholders may be
called at any time by the Chairman of the Board or by our board of directors.

  Cumulative Voting

     Under the NYBCL, the certificate of incorporation may provide that in all
elections of directors each shareholder is entitled to cumulate such
shareholder's votes. AT&T's charter does not contain such a provision.

  Removal of Directors

     The NYBCL provides that any or all of the directors may be removed for
cause by vote of the shareholders and, if the certificate of incorporation or
the specific provisions of a by-law adopted by the shareholders provide,
directors may be removed for cause by action of the board of directors. If the
certificate of incorporation or the by-laws so provide, any or all of the
directors may be removed without cause by vote of the shareholders.

     Neither AT&T's charter nor the AT&T by-laws provide that directors may be
removed without cause by action of the shareholders or that directors may be
removed by our board of directors.

  Vacancies

     The certificate of incorporation or by-laws may provide that newly created
directorships or vacancies are to be filled by vote of the shareholders. Unless
the certificate of incorporation or the specific provisions of a by-law adopted
by the shareholders provide that the board of directors may fill vacancies
occurring on the board of directors by reason of the removal of directors
without cause, such vacancies may be filled only by vote of the shareholders. A
director elected to fill a vacancy, unless elected by the shareholders, will
hold office until the next meeting of shareholders at which the election of
directors is in the regular order of business and until his or her successor has
been elected and qualified.

                       COMPARISON OF RIGHTS OF HOLDERS OF
            AT&T COMMON STOCK AND AT&T WIRELESS GROUP TRACKING STOCK
                             PRIOR TO THE SPIN-OFF

     We summarize below the material differences between the rights of holders
of AT&T common stock and holders of AT&T Wireless Group tracking stock. We do
not intend for this summary to be a complete statement of the rights of holders
of shares of AT&T Wireless Group tracking stock or a comprehensive comparison
with the rights of the holders of shares of AT&T common stock, or a complete
description of the specific provisions referred to in this summary. For more
information on AT&T's capital stock, see "Description of AT&T Capital Stock" on
page 101.

     If you exchange your shares of AT&T common stock for shares of AT&T
Wireless Group tracking stock, until the spin-off is completed you will remain a
common stockholder of AT&T Corp., but you will have different rights as a result
of AT&T's corporate structure. The rights of holders of AT&T common stock and
holders of AT&T Wireless Group tracking stock are defined and governed by the
AT&T charter, the AT&T by-laws and the NYBCL.

     We do not intend that this identification of specific differences is to
indicate that other equally or more significant differences do not exist. This
summary is qualified in its entirety by reference to the NYBCL, AT&T's charter
and AT&T's by-laws, to which holders of shares of AT&T common stock are
referred. Copies of the governing corporate instruments of AT&T have been filed
with the SEC. For information about how to obtain copies, see "Where You Can
Find More Information."

VOTING RIGHTS

     Currently, holders of AT&T common stock have one vote per share, holders of
Class B Liberty Media Group tracking stock have 0.375 of a vote per share,
holders of Class A Liberty Media Group tracking stock have 0.0375 of a vote per
share, and holders of AT&T Wireless Group tracking stock have 0.5 of a vote per
share. This voting power is subject to adjustment for stock splits, stock
dividends and combinations, including any distribution of AT&T Wireless Group
tracking stock to holders of AT&T common stock. Except as otherwise required by
New York law or any special voting rights of any class or series of AT&T
preferred stock, Liberty Media Group tracking stock or any other class of AT&T
common shares, holders of shares of AT&T common stock, AT&T Wireless Group
tracking stock, each other class of AT&T common shares, if any, that is entitled
to vote, Class A Liberty Media Group tracking stock and Class B Liberty Media
Group tracking stock, and holders of shares of each class or series of AT&T
preferred stock, if any, that is entitled to vote, will vote as one class with
respect to all matters to be voted on by shareholders of AT&T. No separate class
vote of AT&T Wireless Group tracking stock will be required, except as required
by the NYBCL.

DIVIDENDS

     Provided that AT&T has sufficient assets to pay a dividend under applicable
law, after excluding the available dividend amount relating to the Liberty Media
Group, dividends on AT&T Wireless Group tracking stock are limited to an
available dividend amount that is designed to be equivalent to the amount that
would legally be available for dividends on that stock if the AT&T Wireless
Group were a stand-alone corporation. Dividends on AT&T common stock are limited
to the amount of legally available funds for all of AT&T less the sum of the
available dividend amount for AT&T Wireless Group tracking stock and the
available dividend amount for Liberty Media Group tracking stock.

     Provided that there are sufficient assets to pay a dividend on a class of
stock, our board of directors will have the sole authority and discretion to
declare and pay dividends (or to refrain from declaring or paying dividends), in
equal or unequal amounts, on AT&T common stock, AT&T Wireless Group tracking
stock, Liberty Media Group tracking stock, any other class of AT&T common shares
or any two or more of such classes. Subject to not exceeding the applicable
available dividend amount, our board of directors has this power regardless of
the relative available dividend amounts, prior dividend amounts declared,
liquidation rights or any other factor. Our board of directors has adopted a
policy with respect to Liberty Media Group tracking stock that it will
distribute to the holders of Liberty Media Group tracking stock, subject to
legal restrictions, any dividends and distributions it receives from any entity
included in the Liberty Media Group.

REDEMPTION

     AT&T common stock is not subject to redemption. At any time following
either the occurrence of tax-related events or May 2, 2002 and in the event of
certain significant transactions, our board of directors, in its sole
discretion, may redeem all outstanding shares of AT&T Wireless Group tracking
stock for shares of AT&T common stock. In addition, AT&T Wireless Group tracking
stock may be mandatorily exchanged for shares of a subsidiary holding
substantially all of the assets of the AT&T Wireless Group. For more information
on redemption of AT&T Wireless Group tracking stock, see "Description of AT&T
Capital Stock -- AT&T Wireless Group Tracking Stock -- Redemption" on page 105.

LIQUIDATION

     In the event of a liquidation, dissolution or winding up of AT&T, whether
voluntary or involuntary, AT&T will first pay or provide for payment of debts
and other liabilities of AT&T, including the liquidation preferences of any
class or series of AT&T preferred stock. Thereafter, holders of the shares of
AT&T common stock, Liberty Media Group tracking stock, AT&T Wireless Group
tracking stock and any other class of AT&T common shares will share in the funds
of AT&T remaining for distribution to its common shareholders in proportion to
the aggregate market capitalization of the outstanding shares of each class of
stock, as applicable, to the aggregate market capitalization of all the classes
of AT&T common stock. AT&T will calculate the market capitalizations based on
the 20-trading day period ending on the trading day prior to the date of the
public announcement of the liquidation, dissolution or winding up of AT&T.

                                  THE SPIN-OFF

     Under AT&T's restructuring plan announced October 25, 2000, each of AT&T's
major business units, AT&T Wireless, AT&T Broadband, AT&T Consumer and AT&T
Business, would become a publicly traded company, represented either by a
tracking stock or an asset-based common stock.

     Following completion of this exchange offer, the issued and outstanding
shares of AT&T Wireless Group tracking stock will represent only a portion of
the economic value of AT&T Wireless Group. AT&T Common Stock Group will continue
to retain the remaining interest in AT&T Wireless Group in the form of a
retained inter-group interest. As such, AT&T Wireless Group will continue to be
a part of AT&T following completion of this exchange offer. However, subject to
a number of conditions and circumstances which are described below, AT&T intends
to spin-off AT&T Wireless Group from AT&T.

     We expect that this spin-off would be accomplished through the following
steps, any or all of which may be effected simultaneously:

     -  Transfer all of the assets and liabilities of AT&T Wireless Group to
        AT&T Wireless Services, a subsidiary of AT&T that currently holds a
        substantial amount of the assets of AT&T Wireless Group.

     -  Mandatorily exchange, in accordance with the terms of AT&T's charter,
        all issued and outstanding shares of AT&T Wireless Group tracking stock,
        including the shares of AT&T Wireless Group tracking stock issued in
        this exchange offer and to DoCoMo, in exchange for the securities of
        AT&T Wireless Group it then holds, for shares of common stock of AT&T
        Wireless Services.

     -  Distribute all of the remaining shares of AT&T Wireless Services, held
        by AT&T in respect of its inter-group retained interest, on a pro rata
        basis, to holders of AT&T common stock.

     The specific terms and conditions of the spin-off of AT&T Wireless Services
are expected to be governed by a separation and distribution agreement to be
entered into among AT&T and AT&T Wireless Services. The material expected terms
of this separation and distribution agreement are summarized below.

     In addition, we expect that AT&T and AT&T Wireless Services will enter into
a number of other agreements in connection with the spin-off. We expect these
agreements to include:

     - brand license agreement

     - network services agreements

     - agency and referral agreement

     - employee benefits agreement

     - intellectual property agreement

     - tax sharing agreement

     - interim and other services agreements

The material expected terms of these agreements are described below. However, we
do not expect that any of these agreements will be entered into until
immediately prior to the spin-off, and each of AT&T and AT&T Wireless Services
reserves the right to materially change the terms of these agreements.

SEPARATION AND DISTRIBUTION AGREEMENT

     The following summary of the expected form of the separation and
distribution agreement does not purport to be complete, and it is qualified in
its entirety by the form of separation and distribution agreement which has been
filed as an exhibit to the registration statement of which this document is a
part.

     The separation and distribution agreement sets forth the agreements among
AT&T and AT&T Wireless Services with respect to the principal corporate
transactions required to effect the spin-off, and a number of other agreements
governing the relationship between AT&T Wireless Services and AT&T following the
spin-off. We expect to execute the separation and distribution agreement
immediately prior to the spin-off. We only expect to enter into the separation
and distribution agreement, and to complete the spin-off, if specified
conditions are met. These conditions include, among others, receipt of a
favorable ruling on the spin-off from the Internal Revenue Service, the
satisfaction by AT&T of a number of conditions in a new credit agreement that
AT&T expects to enter into and the receipt of other approvals.
                                       114
<PAGE>   121

     Specifically, AT&T expects to enter into a new $25 billion bank facility.
The commitment letter with respect to this bank facility provides, and the
definitive credit agreement is expected to provide, that AT&T cannot effect
specified transactions, including the distribution of AT&T Wireless Group in the
spin-off, unless

     - AT&T's public debt rating for its long-term senior debt is at least BBB+
       by Standard & Poor's Ratings Services and Baa1 by Moody's Investors
       Service, Inc.

     - there are no defaults or events of default under the credit agreement,

     - the preferred equity interest in AT&T Wireless Group held by, and
       intercompany indebtedness owed by AT&T Wireless Group to, AT&T is repaid
       and

     - required prepayments of the credit facility are made.

AT&T's current long-term debt ratings are A on CreditWatch with negative
implications by Standard and Poor's and A2 under review for possible downgrade
by Moody's.

     While we currently intend to complete the spin-off, we cannot assure you
that these conditions will be met or that, even if these conditions are met, the
spin-off will occur or that if the spin-off does occur that it will occur on the
terms or in the manner described, or in the time frame contemplated.

  The Separation

     In the separation and distribution agreement, AT&T will agree to transfer,
or to cause its subsidiaries to transfer, to AT&T Wireless Services:

     - all assets attributed to AT&T Wireless Group by AT&T's charter that are
       not then held by AT&T Wireless Services;

     - all assets reflected in the most recent balance sheet of AT&T Wireless
       Group that are not then held by AT&T Wireless Services;

     - specified contracts which relate to AT&T Wireless Group; and

     - other specified assets.

These assets are referred to as the "additional wireless group assets."

     AT&T Wireless Services will also agree to assume or fulfill:

     - all liabilities attributed to AT&T Wireless Group by AT&T's charter to
       which AT&T Wireless Services or its subsidiaries is not then subject;

     - all liabilities reflected in the most recent balance sheet of AT&T
       Wireless Group to which AT&T Wireless Services is not then subject;

     - all liabilities to the extent arising out of, relating to or resulting
       from the operations of AT&T Wireless Group including its contracts and
       assets;

     - all liabilities to the extent arising out of, relating to or resulting
       from terminated, divested or discontinued businesses and operations that
       were part of AT&T Wireless Group immediately prior to termination,
       divestiture or discontinuation;

     - all liabilities to the extent arising out of, relating to or resulting
       from, a specified list of litigations;

     - all liabilities to the extent arising out of, relating to or resulting
       from the provision, or failure to provide, telecommunications services by
       AT&T Wireless Group;

     - a portion of the liabilities, if any, resulting out of an action relating
       to AT&T Wireless Group's assets in Malaysia, subject to certain
       adjustments;

     - a portion of the liabilities, if any, arising out of specified purported
       securities class actions litigations to the extent relating to AT&T
       Wireless Group tracking stock;

     - specified liabilities resulting from the spin-off;

     - obligations and commitments under a specified list of contracts; and

     - other specified liabilities.

                                       115
<PAGE>   122

These liabilities are referred to as "additional wireless group liabilities."

     Generally, neither AT&T nor AT&T Wireless Services will make any
representation or warranty as to:

     - the assets, businesses or liabilities transferred or assumed;

     - any consents or approvals required in connection with that transfer or
       assumption;

     - the value or freedom from any lien or other security interest of any of
       the additional wireless group assets; and

     - the absence of any defenses or freedom from counterclaim relating to any
       claim of any person, or as to the legal sufficiency of any assignment,
       document or instrument delivered to convey title to any asset
       transferred.

In addition, the wireless group assets are being transferred on an "as is,"
"where is" basis, and AT&T Wireless Services will agree to bear the economic and
legal risks that the conveyance is insufficient to vest good and marketable
title, free and clear of any lien or other security interest.

     In order to facilitate these transfers and assumptions, each of AT&T and
AT&T Wireless Services will agree to execute and deliver those deeds,
assignments, bills of sale, stock powers and other instruments of transfer or
conveyance as may be necessary. Each of AT&T and AT&T Wireless Services will
also agree to take such further actions as may be necessary to effectuate these
transfers and assumptions, including obtaining any required governmental
consents.

     AT&T and AT&T Wireless Services will generally also agree to terminate all
agreements, understandings and arrangements among AT&T and AT&T Wireless
Services with specified exceptions. AT&T Wireless Services will agree, upon
completion of the spin-off, to repay the full amount of the principal and
accrued but unpaid interest of all outstanding indebtedness owed by AT&T
Wireless Group to AT&T and the face value and accrued but unpaid dividends on
all preferred stock in AT&T Wireless Group held by AT&T.

  The Mandatory Exchange and the Distribution

     Following completion of the transactions described under "-- The
Separation," AT&T would deliver to an exchange agent a stock certificate
representing the shares of AT&T Wireless Services common stock that will be
delivered in exchange for shares of AT&T Wireless Group tracking stock. AT&T
would then deliver to the exchange agent a stock certificate representing the
shares of AT&T Wireless Services common stock issued to AT&T in respect of its
retained inter-group interest in the mandatory exchange, which will be
distributed pro rata to holders of AT&T common stock.

     AT&T will issue no fractional shares in either the mandatory exchange or
the distribution, and, instead, will issue cash to holders of AT&T common stock
and AT&T Wireless Group common stock in lieu of those fractional shares.

  Reduction in Retained Inter-Group Interest

     The separation and distribution agreement will provide that in
consideration of the liabilities and obligations that would be assumed by AT&T
Wireless Services in the employee benefits agreement, including the obligation
to assume a portion of AT&T's employee stock options, AT&T will, effective
immediately prior to the spin-off, reduce its retained inter-group interest by
12,577,650 nominal shares of AT&T Wireless Group tracking stock. As of
            , based on the closing trading price of AT&T Wireless Group tracking
stock, this reduction had a value of approximately $     million. For more
information on the liabilities and obligations that AT&T Wireless Services will
assume in the employee benefits agreement, please see "Relationship between AT&T
and AT&T Wireless Services following the Spin-Off -- Employee Benefits
Agreement" on page [  ].

  Releases and Indemnification

     The separation and distribution agreement generally will provide for a full
and complete release and discharge as of the date of the completion of the
mandatory exchange of all liabilities existing or arising from all acts and
events occurring or failing to occur or alleged to have occurred or to have
failed to occur and all conditions existing or alleged to have existed on or
before the date of the completion of the mandatory
                                       116
<PAGE>   123

exchange, between or among AT&T and its affiliates, on the one hand, and AT&T
Wireless Services and its affiliates, on the other hand, including any
contractual agreements or arrangements existing or alleged to exist between or
among those parties on or before that date.

     AT&T Wireless Services will agree to indemnify, defend and hold harmless
AT&T and its affiliates, and each of their directors, officers and employees,
from and against all liabilities relating to, arising out of or resulting from:

     - the failure of AT&T Wireless Services or its affiliates, or any other
       person to pay, perform or otherwise promptly discharge any of the
       liabilities of the AT&T Wireless Group or additional wireless group
       liabilities;

     - any liabilities of AT&T Wireless Group or additional wireless group
       liabilities;

     - any breach by AT&T Wireless Services or its affiliates of the separation
       and distribution agreement or any of the ancillary agreements entered
       into in connection with the separation and distribution agreement; and

     - specified disclosure liabilities.

     AT&T will agree to indemnify, defend and hold harmless AT&T Wireless
Services and its affiliates, and each of their directors, officers and
employees, from and against all liabilities relating to, arising out of or
resulting from:

     - the failure of AT&T or its affiliates or any other person to pay, perform
       or otherwise promptly discharge any liabilities of AT&T, other than
       liabilities of AT&T Wireless Group or additional wireless group
       liabilities;

     - any liabilities of AT&T, other than liabilities of AT&T Wireless Group or
       additional wireless group liabilities;

     - any breach by AT&T or its affiliates of the separation and distribution
       agreement or any of the ancillary agreements entered into in connection
       with the separation and distribution agreement; and

     - specified disclosure liabilities.

     The separation and distribution agreement also specifies procedures for
claims for indemnification made under the provisions described above.

  Agreement on Spin-Off Taxes and Limitations on Future Transactions

     Under the separation and distribution agreement, AT&T Wireless Services, is
responsible for any tax liability and any related liability (e.g. interest,
penalties, accounting, legal and other professional fees, etc.) that results
from the spin-off failing to qualify as a tax-free transaction, unless any such
liability was caused by (1) the inaccuracy of certain factual representations
made by AT&T in connection with obtaining a private letter ruling from the IRS
(or in connection with obtaining a tax opinion), or (2) a post spin-off
transaction with respect to the stock or assets of AT&T.

     In addition, AT&T Wireless Services has agreed that, for a period of 30
months from the date of the distribution:

     - it will continue to be a company engaged in the active conduct of a trade
       or business as defined in Section 355(b) of the Internal Revenue Code.

     - it will not enter into any transaction or transactions as a result of
       which any person or group of related persons would acquire, or have the
       right to acquire, AT&T Wireless Services stock that represents more than
       five percent of the vote or value of all outstanding shares of AT&T
       Wireless Services stock unless (1) AT&T determines that such transaction
       or transactions would not render the spin-off taxable, or (2) AT&T or
       AT&T Wireless Services, at AT&T's election, obtains a tax opinion or
       private letter ruling from the IRS confirming that the subsequent
       transaction will not render the spin-off taxable.

                                       117
<PAGE>   124

  Termination

     The separation and distribution agreement will provide that it may be
terminated at any time prior to the completion of the distribution by AT&T in
its sole discretion. If AT&T terminates the separation and distribution
agreement, neither party will have any liability or further obligation to any
other party.

  Amendments and Waivers

     The separation and distribution agreement will provide that no provisions
of it or any ancillary agreement will be deemed waived, amended, supplemented or
modified by any party unless the waiver, amendment, supplement or modification
is in writing and signed by the authorized representative of the party against
whom that waiver, amendment, supplement or modification is sought to be
enforced.

                  RELATIONSHIP BETWEEN AT&T AND AT&T WIRELESS
                        SERVICES FOLLOWING THE SPIN-OFF

BRAND LICENSE AGREEMENT

     AT&T and AT&T Wireless Services expect to enter into a brand license
agreement pursuant to which AT&T Wireless Services will have rights, on a
royalty-free basis (subject to the payment of a maintenance fee described
below), to continue to use specified AT&T brands, including the AT&T globe
design and the AT&T trade dress. Under the brand license agreement, AT&T
Wireless Services will be entitled to use these AT&T brands, alone or in
combination with AT&T Wireless Services' other marks, for the provision of its
mobile cellular services, including so-called third generation services, its
residential fixed wireless services and certain ancillary products and services
for a period of five years following the completion of the spin-off. After the
initial five-year period, AT&T Wireless Services will be entitled, if it
chooses, to continue to use these AT&T brands on these services for an
additional five-year period. During the second five-year period, AT&T Wireless
Services may terminate the brand license agreement by providing 12 months prior
notice. In addition, AT&T Wireless Services may continue to use these AT&T
brands after the brand license agreement is terminated during a one-year
transition period.

     AT&T Wireless Services will have the exclusive right to use these AT&T
brands in connection with its wide-area mobile cellular services, aircraft to
ground services, and specified ancillary wireless services. AT&T Wireless
Services will have the non-exclusive right to use these AT&T brands in
connection with its residential fixed wireless services in certain territories
(provided that AT&T cannot license the brands to third parties for residential
fixed wireless services or to third parties providing residential telephony or
high speed data services competing with residential fixed wireless services
unless AT&T provides a component of such service) and on specified content,
equipment and software associated with the AT&T Wireless Services' services as
well as on certain wireless devices, portals and promotional products. For two
years following the completion of the spin-off, AT&T Wireless Services reserves
the right to obtain a non-exclusive license to use these AT&T brands for
specified small business fixed wireless services if a distribution agreement is
reached with AT&T relating to AT&T Wireless Services' provision to AT&T of fixed
wireless services.

     The territory of the brand license agreement is generally worldwide with
exceptions where AT&T has already granted brand license agreements, e.g.,
Canada, Mexico, Republic of China, parts of India, or where another AT&T unit
has exclusive brand rights for related services. Subject to certain conditions
set forth in the brand license agreement, AT&T Wireless Services may also extend
certain rights to use these AT&T brands to authorized dealers of AT&T Wireless
Services' services. The brand license agreement provides that AT&T Wireless
Services will comply with specified quality, customer care, graphics and
marketing standards in connection with the use of these AT&T brands. It also
provides that, for so long as AT&T Wireless Services uses these AT&T brands, it
will pay AT&T a brand maintenance fee for the administration, protection and
promotion of these AT&T brands. AT&T may terminate the brand license agreement
in the event of a significant breach, as defined in the brand license agreement,
and a change of control of AT&T Wireless Services.

NETWORK SERVICES AGREEMENTS

     AT&T and AT&T Wireless Services expect to enter into a network services
agreement under which AT&T will provide voice and data telecommunications
services to AT&T Wireless Services for a five year term. The services that will
be covered under the network services agreement include both wholesale services,
which AT&T Wireless Services will use as a component of wireless services it
provides to its customers, and administrative services, for example corporate
usage with respect to which AT&T Wireless will use itself.

     Under the terms and conditions of the network services agreement, AT&T
Wireless Services will have an annual base purchase commitment for domestic
voice services equal to AT&T Wireless Services actual usage in 2001. The pricing
on which AT&T provides these services will be subject to internal and external
benchmarking. Any growth in AT&T Wireless' services needs for these domestic
voice services above that base purchase commitment is not committed to AT&T,
although AT&T has a right to match any third party
                                       119
<PAGE>   126

offers until 2003 for 80% of that growth. Thereafter, for the remainder of the
term of the network services agreement, AT&T Wireless Services may award its
business above the commitment to any carrier.

     In addition, AT&T Wireless will agree to purchase all international voice
services from AT&T for the term of the network services agreement. The pricing
on which AT&T provides these services will be at the price AT&T receives from
Concert, its joint venture with British Telecommunications, without mark-up.

     AT&T Wireless Services' base commitment for administrative services (data
and voice) will be set at 80% of 2000 purchases. With respect to AT&T Wireless
Services' needs for local connectivity, business will be awarded to AT&T if AT&T
meets committed levels of performance, and offers price and performance terms at
least as favorable as those offered by other providers.

     AT&T and AT&T Wireless Services also expect to enter into other commercial
agreements, including agreements governing the physical interconnection of their
networks and other intercarrier arrangements, SS7 signaling services to be
provided by AT&T Wireless Services to AT&T's business services unit, a 38 GHz
license to be provided by AT&T Wireless Services to AT&T's business services
unit, agreements under which AT&T will provide space and power in various AT&T
locations for AT&T Wireless Services' equipment and an agreement under which
AT&T Wireless Services will provide wireless services to AT&T for administrative
purposes.

AGENCY AND REFERRAL AGREEMENT

     AT&T and AT&T Wireless Services also expect to enter into an agency and
referral agreement that covers AT&T's acting as an agent on AT&T Wireless
Services' behalf to assist AT&T Wireless Services in obtaining business with
AT&T's business customers.

EMPLOYEE BENEFITS AGREEMENT

     AT&T and AT&T Wireless Services expect to enter into an employee benefits
agreement that will govern the employee benefit obligations of AT&T Wireless
Services, including both compensation and benefits, with respect to active
employees and retirees assigned to AT&T Wireless Group. In general, pursuant to
the employee benefits agreement, AT&T Wireless Services will be responsible for
all liabilities relating to employees or former employees of AT&T Wireless
Services, and their dependents and beneficiaries, other than those liabilities
relating to employment by AT&T for periods on or before the last date as of
which AT&T Wireless Services is a member of AT&T's controlled group within the
meaning of Section 414 of the Internal Revenue Code, which date is sometimes
referred to as the "disposition date," that are expressly retained by AT&T. Each
plan maintained by AT&T Wireless Services shall provide that each employee of
AT&T Wireless Services or any of its affiliates as of the disposition date, each
sometimes referred to as a "transferred individual," will receive full
recognition and credit under each AT&T Wireless Services plan for all service
with AT&T or its affiliates for purposes of determining eligibility to
participate, vesting and the schedule of benefits under each AT&T Wireless
Services plan in which such employee will otherwise be eligible to participate.

     AT&T and AT&T Wireless Services will establish a procedure by which each
transferred individual who has an account under the AT&T defined contribution
plans may make a one-time election to have such account transferred to the AT&T
Wireless Services 401(k) Plan. As of the disposition date, all account balances
of transferred individuals in the AT&T defined contribution plans will be
immediately vested. AT&T will make a one-time payment to certain transferred
individuals who, immediately prior to the close of the disposition date,
performed services for AT&T Wireless Services as employees of AT&T or an AT&T
entity, each sometimes referred to as an "AT&T Transferee," in the year
following the calendar year in which the disposition date occurs, of the amount
of "lost savings plan matching contributions," if any, to which they would have
been entitled under existing AT&T practices with respect to compensation earned
on or before the disposition date that is in excess of the annual limits imposed
by Section 401(a)(17) of the Internal Revenue Code.

     Effective immediately after the disposition date, AT&T Wireless Services
will assume all liabilities, and be assigned all rights, under certain
individual agreements made by AT&T or an AT&T entity with AT&T transferees.

                                       120
<PAGE>   127

     Effective immediately after the disposition date, and thereafter,
transferred individuals will be entitled to distribution of their accounts under
the AT&T Employee Stock Ownership Plan.

     Effective as of the disposition date, the AT&T pension plans will be
amended to provide that:

     - each transferred individual will vest, as of the disposition date, in his
       or her accrued benefit under the AT&T pension plans;

     - all unbridged net credited service of certain transferred individuals
       will be bridged, provided that the unbridged net credited service would
       have been eligible for bridging under the bridging rules of the AT&T
       pension plans in the event that the transferred individual had continued
       to be employed as an "Employee" under the AT&T pension plans and
       satisfied the applicable bridging rules under those plans; and

     - certain transferred individuals will be deemed to have completed any
       minimum period of net credited service that is required to convert his or
       her accrued benefit to a cash balance account.

     In general, pursuant to the employee benefits agreement, all liabilities
relating to health and welfare coverage or claims and workers compensation
claims incurred by or on behalf of transferred individuals or their covered
dependents under the AT&T health and welfare plans on or before the disposition
date will remain liabilities of AT&T, and all liabilities relating to health and
welfare coverage or claims incurred by or on behalf of transferred individuals
or their covered dependents after the disposition date will be liabilities of
AT&T Wireless Services.

     For the one-year period immediately after the disposition date, AT&T
Wireless Services will provide severance payments to AT&T transferees eligible
to receive severance benefits under AT&T Wireless Services' severance plan in an
amount not less than the greater of the severance payments that the AT&T
transferees would have received under the AT&T Force Management Program or the
severance payments payable under the AT&T Wireless Services severance plan. In
addition, AT&T and AT&T Wireless Services will cooperate to establish, prior to
the disposition date, "change in control" benefits applicable to AT&T Wireless
Services.

     AT&T Wireless Services will be responsible for determining all awards that
would otherwise be payable under the AT&T Short Term Incentive Plan and the AT&T
Bonus Plan to Transferred Individuals for the calendar year in which the
disposition date occurs.

     Pursuant to the employee benefits agreement, AT&T Wireless Services has
agreed to consider the issuance of a guarantee of, or to pursue issuance of an
insurance policy for, payments to certain AT&T transferees (the present value of
which is presently estimated to be $83 million), under the AT&T Senior
Management Incentive Award Deferral Plan. This guarantee would be contingent on
payments not being paid to transferred individuals when due, by AT&T, any AT&T
entity or any successor as a result of the financial inability of AT&T or an
AT&T entity to make such payments, subject to specified conditions.

     For periods after the disposition date, AT&T will retain all liabilities
relating to transferred individuals under the AT&T Non-Qualified Pension Plan,
the AT&T Excess Benefit and Compensation Plan, the AT&T Mid-Career Pension Plan,
the AT&T Senior Management Long Term Disability and Survivor Protection Plan,
and any individual nonqualified pension arrangements as of the disposition date,
and will make benefit payments to transferred individuals at such times and in
such manner as is provided for under the terms of the respective nonqualified
pension plans and arrangements.

     Prior to the disposition date, AT&T will cause AT&T Wireless Services to
adopt the Wireless Long Term Incentive Plan, which plan will have terms and
conditions substantially similar to the AT&T Long Term Incentive Plan.

     Each AT&T option granted prior to January 1, 2001, that is outstanding as
of the date that the AT&T Wireless Services stock held by AT&T is distributed to
holders of AT&T common stock (referred to as the "distribution date"), will be
adjusted so that each holder of such AT&T option will receive, immediately after
the distribution, adjusted AT&T options and, under an AT&T Wireless Services
Long Term Incentive Plan, AT&T Wireless Services options. The combined intrinsic
value of the adjusted AT&T option and the AT&T Wireless Services option held by
each holder of an adjusted AT&T option will equal the intrinsic value of the
AT&T option held by such holder immediately before the distribution date.

                                       121
<PAGE>   128

     The exercise price per share of AT&T common stock subject to an adjusted
AT&T option will be equal to the product of (A) the exercise price per share of
the AT&T option with respect to which an adjustment is being made and (B) the
quotient obtained by dividing the opening stock price of AT&T on the first
trading day after the distribution date by the closing stock price of AT&T on
the distribution date. The exercise price per share of AT&T Wireless Services
common stock subject to an AT&T Wireless Services option will be equal to the
product of (x) the exercise price per share of the AT&T option with respect to
which the AT&T Wireless Services option is granted immediately before the
distribution date and (y) the quotient obtained by dividing the opening price of
AT&T Wireless Services stock on the first trading day after the distribution
date, by the closing stock price of AT&T on the distribution date.
Notwithstanding the foregoing, if the distribution occurs while the NYSE is open
for trading, the opening and closing stock prices of AT&T and the opening stock
price of AT&T Wireless Services will be based on the initial or last trading
prices of such stock immediately after or before the distribution, as the case
may be.

     The number of shares of AT&T Wireless Services common stock subject to an
AT&T Wireless Services option, granted with respect to an adjusted AT&T option,
immediately after the distribution will equal the product of the number of
shares of AT&T common stock subject to the AT&T option outstanding as of the day
before the distribution date times a fraction, the numerator of which is the
number of shares of AT&T Wireless Services common stock beneficially owned by
AT&T or an AT&T entity (other than any Wireless entity, an AT&T pension plan
trust or an AT&T Savings Plan trust) on the record date for the distribution and
the denominator of which is the number of shares of AT&T common stock
outstanding on the record date for the distribution.

     The number of shares of AT&T common stock subject to an adjusted option
immediately after the distribution will equal the quotient obtained by dividing
(a)the intrinsic value of the original AT&T option based on the closing stock
price of AT&T on the distribution and the exercise price per share of the
original AT&T option based on the closing stock price of AT&T on the
distribution and the exercise price per share of the original AT&T option minus
the intrinsic value of the AT&T Wireless Services option granted with respect to
the adjusted AT&T option, by (b) the spread between the opening stock price of
AT&T on the first trading day after the distribution date and the exercise price
of the such adjusted AT&T option as set forth above.

     Each AT&T option granted on or after January 1, 2001, that is outstanding
under an AT&T Long Term Incentive Plan as of the distribution date, will be
adjusted so that each holder of such an AT&T option will receive, immediately
after the distribution, adjusted AT&T options under which the intrinsic value of
the adjusted option held by such individual immediately after the distribution
equals the intrinsic value of the option held by such individual immediately
before the distribution. The exercise price per share of AT&T common stock
subject to such an adjusted AT&T option will be equal to the product of (A) the
exercise price per share of the option with respect to which an adjustment is
being made, and (B) the quotient obtained by dividing the opening stock price of
AT&T on the first trading day after the distribution date by the closing stock
price of AT&T on the distribution date. The number of shares of AT&T common
stock subject to such an adjusted AT&T option immediately after the distribution
will equal the quotient obtained by dividing (x) the product of (i) the spread
between the AT&T closing stock price on the distribution date and the exercise
price per share of the original AT&T option, multiplied by (ii) the number of
shares subject to the original AT&T options, by (y) the spread between the
opening stock price of AT&T on the distribution date and the exercise price per
share of such adjusted option, which spread, in each case, may be a negative
number.

     Each AT&T Wireless Group tracking stock option outstanding under an AT&T
Long Term Incentive Plan as of the exchange date will be converted on the
exchange date into an AT&T Wireless Services option under an AT&T Wireless
Services Long Term Incentive Plan for the number of shares of AT&T Wireless
Services common stock equal to the number of shares of AT&T Wireless Group
tracking stock subject to the AT&T Wireless Group tracking stock option
immediately before the exchange date. The exercise price per share of AT&T
Wireless Services common stock subject to the AT&T Wireless Services option will
equal the exercise price per share of the AT&T Wireless Group tracking stock
option immediately before the exchange date.

                                       122
<PAGE>   129

     Each AT&T option held by a transferred individual will be fully vested and
will continue to be exercisable after the distribution date for the remaining
scheduled term of such option. Each AT&T Wireless Services option held by an
AT&T employee received in exchange for an AT&T Wireless Group tracking stock
option will be fully vested and will continue to be exercisable after the
distribution date for the remaining scheduled term of the original AT&T Wireless
Group tracking stock option. Each AT&T Wireless Services option issued to an
AT&T employee as part of the adjustment to an AT&T option will be fully vested
and will continue to be exercisable after the distribution date for the
remaining scheduled term of the original AT&T option with respect to which the
AT&T Wireless Services option was received. Each AT&T Wireless Services option
held by a transferred individual and received in exchange for an AT&T Wireless
Group tracking stock option, will be subject to the same terms and conditions
regarding term, vesting, and other provisions regarding exercise as set forth in
the original AT&T Wireless Group tracking stock option. Each adjusted AT&T
option held by an AT&T employee will have the same vesting schedule as the
original AT&T option.

     AT&T will issue the shares of AT&T common stock under each of the adjusted
AT&T options and AT&T Wireless Services will issue the shares of AT&T Wireless
Services common stock under each of the AT&T Wireless Services options.

     All AT&T restricted shares or restricted stock units outstanding as of the
distribution date will be adjusted so that each AT&T employee who is the holder
of an AT&T restricted share or restricted stock unit will receive, immediately
after the distribution date, a number of AT&T restricted shares or restricted
stock units equal to the product of (A) the number of restricted shares or
restricted stock units held by such AT&T employee immediately before the
distribution date multiplied by (B) the quotient obtained by dividing the AT&T
closing stock price on the distribution date by the AT&T opening stock price on
the first trading day after the distribution date. Each transferred individual
who is the holder of an AT&T restricted share or restricted stock unit will
receive, immediately after the distribution date, in exchange for each such AT&T
restricted share or restricted stock unit, a number of AT&T Wireless Services
restricted shares or restricted stock units under the applicable AT&T Wireless
Services Long Term Incentive Plan equal to the product of (x) the number of AT&T
restricted shares or restricted stock units held by each transferred individual
immediately before the distribution date multiplied by (y) the quotient obtained
by dividing the AT&T closing stock price by the AT&T Wireless Services opening
stock price on the first trading day after the distribution date. Each
transferred individual will continue to vest in his or her AT&T Wireless
Services restricted stock or units during his or her employment with AT&T
Wireless Services or a related entity. Each AT&T employee will continue to vest
in his or her AT&T award under the AT&T Long Term Incentive Plan during his or
her employment with AT&T and its affiliates and the adjusted award will continue
to be subject to the same terms and conditions which applied to the original
award. Each AT&T Wireless Services award will have the same terms and conditions
as were applicable to the corresponding AT&T award as of the close of the
distribution date, except that references to AT&T and its affiliates will be
modified to refer to AT&T Wireless Services and its affiliates and distribution
equivalent payments, if any, will be payable after the disposition date with
reference to distributions on AT&T Wireless Services common stock, if any.

     Each holder of AT&T performance shares or AT&T stock units that is
outstanding as of the distribution date will be adjusted so that each holder of
such an award will receive, immediately after the distribution date:

     - an award under the AT&T Wireless Services Long Term Incentive Plan for a
       number of AT&T Wireless Services performance shares or AT&T Wireless
       Services stock units, as the case may be, determined by multiplying the
       number of AT&T performance shares or AT&T stock units held as of the
       distribution date by a fraction, the numerator of which is the number of
       shares of AT&T Wireless Services common stock beneficially owned by AT&T
       or an AT&T entity (other than any Wireless entity, an AT&T pension plan
       trust or an AT&T Savings Plan trust) on the record date and the
       denominator of which is the number of shares of AT&T common stock
       outstanding on the record date; and

     - an adjusted award of AT&T performance shares or AT&T stock units for a
       number of AT&T performance shares or AT&T stock units determined by
       dividing (A) the value of AT&T performance shares or AT&T stock units
       held as of the distribution date reduced by the value of the award of
       AT&T Wireless Services performance shares and AT&T Wireless Services
       performance units described

                                       123
<PAGE>   130

       above, by (B) the value of a single AT&T performance share or performance
       unit based on the AT&T opening stock price on the first trading day after
       the distribution date.

Each transferred individual will continue to vest or satisfy service
requirements with respect to his or her AT&T award under the AT&T Long Term
Incentive Plan as if his or her employment with AT&T Wireless Services or one of
its subsidiaries or controlled affiliates were employment with AT&T, and a
termination of such employment will be treated as a termination of employment
from AT&T and its affiliates under the AT&T Long Term Incentive Plan. The
performance criteria of such AT&T award held by a transferred individual will
continue to be based on AT&T measures as determined by the Compensation and
Employee Benefits Committee of the AT&T Board of Directors from time to time,
and the performance criteria for each such AT&T Wireless Services award will be
deemed earned at 100% of target and will otherwise be paid pursuant to the terms
of the original award. Each AT&T employee will vest or satisfy service
requirements with respect to his or her AT&T Wireless Services award under the
AT&T Wireless Services Long Term Incentive Plan as if his or her employment with
AT&T and its affiliates were employment with AT&T Wireless Services or one of
its subsidiaries or controlled affiliates, and a termination of such employment
with AT&T and its affiliates will be treated as a termination of employment with
AT&T Wireless Services and its subsidiaries and affiliates under the AT&T
Wireless Services Long Term Incentive Plan, and each such AT&T Wireless Services
Award will be deemed earned at 100% of target. The performance criteria of each
such AT&T award held by an AT&T employee will continue to be based on AT&T
measures as determined by the Compensation and Employee Benefits Committee of
the AT&T Board of Directors from time to time and will otherwise be paid
pursuant to the terms of the original award. Except with respect to satisfaction
of performance criteria, which will be deemed to have been met as of the day
after the distribution date, the payment of AT&T awards and AT&T Wireless
Services awards to either an AT&T employee or a transferred individual will
continue to be subject to the terms and conditions of the AT&T Long Term
Incentive Plan and the AT&T Wireless Services Long Term Incentive Plan, as in
effect from time to time, provided that, with respect to AT&T Wireless Services
Awards, references to AT&T and its affiliates will be modified to refer to AT&T
Wireless Services and its affiliates and distribution equivalent payments, if
any, will be payable after the disposition date with reference to distributions
on AT&T Wireless Services common stock, if any.

     In consideration of the liabilities and obligations that would be assumed
by AT&T Wireless Services in the employee benefits agreement, including the
obligation to assume a portion of AT&T's employee stock options, AT&T Common
Stock Group will, effective immediately prior to the spin-off, reduce its
retained inter-group interest by 12,577,650 nominal shares of AT&T Wireless
Group tracking stock. As of           ,      , based on the closing price of
AT&T Wireless Group tracking stock, this reduction had a value of approximately
$     million.

INTELLECTUAL PROPERTY AGREEMENTS

     AT&T and AT&T Wireless Services expect to enter into an intellectual
property agreement. The intellectual property agreement will specify the
ownership and license rights in patents, software, copyrights, and trade
secrets, but not the AT&T brands. Under the terms of the intellectual property
agreement, each of the parties grants to the other under its patents a
non-exclusive, fully paid-up, worldwide, perpetual license to make, use and sell
any and all products and services in the conduct of its present and future
business. The parties also grant special rights under certain of each other's
patents for defensive protection, special affiliate licensing, and supplier
sublicensing. In addition, AT&T has agreed to refrain from licensing AT&T
Wireless Services' ten largest domestic mobile service competitors under certain
of AT&T's patents for a period of five years.

     Each party to the intellectual property agreement will own all the
software, trade secrets, and copyrights that it created prior to the spin-off of
AT&T Wireless Services. Each party grants to the other a non-exclusive, fully
paid-up, worldwide, perpetual license to use the party's software, trade
secrets, and copyrights that it currently possesses for use in its present and
future business. Proprietary information related to a party's customers receives
special protection under the agreement.

TAX SHARING AGREEMENT

     In connection with the spin-off, AT&T and AT&T Wireless Services amended
and restated the existing tax sharing agreement dated as of May 2, 2000. As
amended and restated, the tax sharing agreement provides that:

     - AT&T will be responsible for any tax item resulting from the transfer to
       AT&T of certain assets that are not attributed to AT&T Wireless Group
       that are currently held by a member of AT&T Wireless Group;

     - the intercompany account between AT&T and AT&T Wireless Group will be
       adjusted to reflect either party's liability for or right to receive any
       unpaid amounts under the tax sharing agreement with respect to
       pre-spin-off periods;

     - no tax sharing payments will be made with respect to taxable periods (or
       portions thereof) beginning after the date of the distribution; and

     - the responsibility for taxes and related liabilities resulting from a
       failure of the spin-off to qualify as a tax-free transaction will be
       governed by the separation and distribution agreement.

     In addition, the amended and restated tax sharing agreement contains
provisions that govern tax contests and other related matters (e.g., exchange of
information, dispute resolution, etc.) with respect to tax periods ending on or
before or deemed to end on the date of the distribution.

SERVICES AGREEMENT

     AT&T and AT&T Wireless Services plan to enter into a Services Agreement.
This agreement is expected to govern the provision by each party to the other
party, on an interim basis, of corporate support services falling into three
categories: (i) common support services; (ii) inter-unit services; and (iii)
systems replication and systems services. With certain exceptions, the term of
the agreement is expected to be 18 months and the individual services provided
for by the agreement are generally terminable on 90 days' notice.

     Common support services.  Common support services include services
historically provided at a corporate headquarters level, such as financial
management, tax, media relations, human resources administration, procurement,
real estate management and other administrative functions. It is expected that
the charges for these services will allow the company that is providing the
service to recover the costs of such service, plus all out-of-pocket costs and
expenses, but without any profit.

     Inter-unit services.  Inter-unit services include services historically
provided by one business unit to another, such as billing, systems development
and customer care. It is expected that the charges for these services will allow
the company that is providing the service to recover the cost of such service,
plus all out-of-pocket costs and expenses. In some instances it is expected that
the company providing the service will recover a profit.

     It is expected that the Services Agreement will also provide for the
provision of additional services identified from time to time after the spin-off
that a party reasonably believes were inadvertently or unintentionally omitted
from the specified services, and that are essential to effectuate an orderly
transition, so long as the provision of these services would not significantly
disrupt the providing party's operations.

     Systems Replication and Systems Service.  It is expected that under this
agreement AT&T will supply to AT&T Wireless Services certain technology systems
and support services. Examples include information technologies network support,
linkages between AT&T Wireless Services's web site and att.com. The charges for
these services will be based on a "cost plus" formula intended to allow the
party supplying the service to recover its fully-allocated cost, plus a profit.
With limited exceptions, the term of the agreement is 18 months and the
agreement is terminable by the party receiving the service on 90 days' notice.

   DESCRIPTION OF AT&T WIRELESS SERVICES CAPITAL STOCK FOLLOWING THE SPIN-OFF

     The following description of the material expected terms of the capital
stock of AT&T Wireless Services does not purport to be complete, and is
qualified in its entirety by reference to the forms of AT&T Wireless Services'
charter and by-laws, copies of which have been filed as exhibits to the
registration statement of which this document is a part. For more information on
how you can obtain copies of these documents, see "Where You Can Find More
Information" on page 125. You are urged to read the forms of charter and by-laws
in their entirety.

GENERAL

     Immediately after the spin-off, we expect AT&T Wireless Services'
authorized capital stock is expected to consist of           shares of preferred
stock, par value $.01, and           shares of common stock, par value $0.01.
Immediately following the spin-off, we expect approximately           shares of
AT&T Wireless Services common stock and no shares of AT&T Wireless Services
preferred stock would be outstanding.

  AT&T WIRELESS SERVICES COMMON STOCK

     The holders of AT&T Wireless Services common stock will be entitled to one
vote for each share on all matters voted on by stockholders, including elections
of directors, and, except as otherwise required by law or provided in any
resolution adopted by AT&T Wireless Services' board of directors with respect to
any series of preferred stock (a "preferred stock designation"), the holders of
AT&T Wireless Services common stock will possess all of the voting power of AT&T
Wireless Services. AT&T Wireless Services' charter will not provide for
cumulative voting in the election of directors. Subject to any preferential
rights of any outstanding series of AT&T Wireless Services preferred stock
created by AT&T Wireless Services' board of directors from time to time, the
holders of AT&T Wireless Services common stock will be entitled to the dividends
as may be declared from time to time by the AT&T Wireless Services' board of
directors from funds legally available for dividends, and upon liquidation will
be entitled to receive pro rata all assets available for distribution to the
holders of AT&T Wireless Services common stock. For a more complete discussion
of AT&T Wireless Services' dividend policy, see "-- Dividend Policy".

  AT&T WIRELESS SERVICES PREFERRED STOCK

     AT&T Wireless Services' charter will authorize AT&T Wireless Services'
board of directors to establish one or more series of preferred stock and to
determine, with respect to any series of preferred stock, the terms and rights
of such series, including, but not limited to:

     - the designation of the series

     - the number of shares of the series, which number AT&T Wireless Services'
       board of directors may later, except where otherwise provided in the
       preferred stock designation, increase or decrease, but not below the
       number of shares thereof then outstanding

     - whether dividends, if any, will be cumulative or noncumulative, and, in
       the case of shares of any series having cumulative dividend rights, the
       date or dates or method of determining the date or dates from which
       dividends on the shares of the series having cumulative dividend rights
       shall be cumulative

     - the rate of any dividends, or method of determining the dividends,
       payable to the holders of the shares of the series, any conditions upon
       which the dividends will be paid and the date or dates or the method for
       determining the date or dates upon which the dividends will be payable

     - the redemption rights and price or prices, if any, for shares of the
       series

     - the terms and amounts of any sinking fund provided for the purchase or
       redemption of shares of the series

     - the amounts payable on and the preferences, if any, of shares of the
       series in the event of any voluntary or involuntary liquidation,
       dissolution or winding up of AT&T Wireless Services' affairs

                                       126
<PAGE>   133

     - whether the shares of the series will be convertible or exchangeable into
       shares of any other class or series, or any other security, of AT&T
       Wireless Services or any other corporation, and, if so, the specification
       of such other class or series or such other security, the conversion or
       exchange price or prices or rate or rates, any adjustments thereof, the
       date or dates as of which the shares will be convertible or exchangeable
       and all other terms and conditions upon which the conversion or exchange
       may be made

     - restrictions on the issuance of shares of the same series or of any other
       class or series

     - the voting rights, if any, of the holders of the shares of the series

     We believe that the ability of AT&T Wireless Services' board of directors
to issue one or more series of preferred stock will provide AT&T Wireless
Services with flexibility in structuring possible future financings and
acquisitions, and in meeting other corporate needs that might arise. The
authorized shares of AT&T Wireless Services preferred stock, as well as shares
of AT&T Wireless Services common stock, will be available for issuance without
further action by AT&T Wireless Services stockholders, unless required by
applicable law or the rules of any stock exchange or automated quotation system
on which AT&T Wireless Services securities may be listed or traded. The NYSE
currently requires stockholder approval as a prerequisite to listing shares in
several instances, including where the present or potential issuance of shares
could result in an increase of at least 20% in the number of outstanding shares
of common stock, or in the amount of voting securities, outstanding. If the
approval of AT&T Wireless Services stockholders is not required for the issuance
of shares of AT&T Wireless Services preferred stock or common stock, the AT&T
Wireless Services board of directors may determine not to seek stockholder
approval.

     Although we believe AT&T Wireless Services' board of directors will have no
intention of immediately doing so, it could issue a series of preferred stock
that could, depending on the terms of the series, impede the completion of a
merger, tender offer or other takeover attempt. AT&T Wireless Services' board of
directors will make any determination to issue the shares of preferred stock
based on its judgment as to the best interests of AT&T Wireless Services and its
stockholders. AT&T Wireless Services' board of directors, in so acting, could
issue preferred stock having terms that could discourage an acquisition attempt
through which an acquiror may be able to change the composition of AT&T Wireless
Services' board of directors, including a tender offer or other transaction that
some, or a majority, of AT&T Wireless Services stockholders might believe to be
in their best interests or in which AT&T Wireless Services stockholders might
receive a premium for their stock over the then current market price of AT&T
Wireless Services common stock.

     We expect that, as of the completion spin-off,           shares of AT&T
Wireless Services Series A junior participating preferred stock will be reserved
for issuance upon exercise of the rights issued under AT&T Wireless Services'
rights agreement. For a more complete discussion of AT&T Wireless Services'
rights plan, see "-- Rights Agreement".

  Dividend Policy

     We do not currently expect that AT&T Wireless Services will pay dividends
on shares of AT&T Wireless Services common stock following completion of the
spin-off in the foreseeable future.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF AT&T WIRELESS SERVICES' CHARTER
AND BY-LAWS

  Board of Directors

     AT&T Wireless Services' charter will provide that, except as otherwise
provided in any preferred stock designation relating to the rights of the
holders of any class or series of preferred stock to elect additional directors
under specified circumstances, the number of directors will be fixed from time
to time exclusively by a resolution adopted by a majority of the total number of
directors which AT&T Wireless Services would have if there were no vacancies, or
the whole board, but shall not be less than three. AT&T Wireless Services'
directors, other than those who may be elected by the holders of any class or
series of our preferred stock having the right under a preferred stock
designation to elect additional directors under specified circumstances, will be
classified into three classes, as nearly equal in number as possible, one class
to be originally

                                       127
<PAGE>   134

elected for a term expiring at the annual meeting of stockholders to be held in
2002, another class to be originally elected for a term expiring at the annual
meeting of stockholders to be held in 2003 and another class to be originally
elected for a term expiring at the annual meeting of stockholders to be held in
2004, with each director to hold office until his or her successor is duly
elected and qualified. Commencing with the 2002 annual meeting of stockholders,
directors elected to succeed directors whose terms then expire will be elected
for a term of office to expire at the third succeeding annual meeting of
stockholders after their election, with each director to hold office until such
person's successor is duly elected and qualified.

     AT&T Wireless Services' certificate of incorporation will provide that,
except as otherwise provided in any Preferred Stock Designation relating to the
rights of the holders of any class or series of preferred stock to elect
directors under specified circumstances, newly created directorships resulting
from any increase in the number of directors and any vacancies on AT&T Wireless
Services' board resulting from death, resignation, disqualification, removal or
other cause will be filled by the affirmative vote of a majority of the
remaining directors then in office, even though less than a quorum of the board,
and not by the stockholders. Any director elected in accordance with the
preceding sentence will hold office for the remainder of the full term of the
class of directors in which the new directorship was created or the vacancy
occurred and until the director's successor shall have been duly elected and
qualified. No decrease in the number of directors constituting AT&T Wireless
Services' board will shorten the term of any incumbent director. Subject to the
rights of any class or series of preferred stock having the right under a
Preferred Stock Designation to elect directors under specified circumstances,
any director may be removed from office only for cause by the affirmative vote
of the holders of at least a majority of the voting power of all voting stock
then outstanding, voting together as a single class.

     These provisions would preclude a third party from removing incumbent
directors and simultaneously gaining control of our board by filling the
vacancies created by removal with its own nominees. Under the classified board
provisions described above, it would take at least two elections of directors
for any individual or group to gain control of AT&T Wireless Services' board.
Accordingly, these provisions could discourage a third party from initiating a
proxy contest, making a tender offer or otherwise attempting to gain control of
AT&T Wireless Services.

  NO STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS

     We expect AT&T Wireless Services' certificate of incorporation and by-laws
to provide that stockholders must effect any action required or permitted to be
taken at a duly called annual or special meeting of stockholders and that those
actions may not be effected by any consent in writing by the holders. Except as
otherwise required by law or by any Preferred Stock Designation, special
meetings of stockholders may be called only by a majority of the Whole Board or
by AT&T Wireless Services' chairman. No business other than that stated in the
notice of meeting may be transacted at any special meeting. These provisions may
have the effect of delaying consideration of a stockholder proposal until the
next annual meeting unless a special meeting is called by AT&T Wireless
Services' board or the chairman of the board.

  ADVANCE NOTICE PROCEDURES

     We expect AT&T Wireless Services' by-laws to establish an advance notice
procedure for stockholders to make nominations of candidates for election as
directors or to bring other business before an annual meeting of stockholders.
These stockholder notice procedures will provide that only persons who are
nominated by AT&T Wireless Services' board, or by a stockholder who was a
stockholder of record at the time of giving notice and has given timely written
notice to our secretary before the meeting at which directors are to be elected,
will be eligible for election as our directors. These stockholder notice
procedures will also provide that at an annual meeting only the business as has
been brought before the meeting by AT&T Wireless Services' board, or by a
stockholder who has given timely written notice to AT&T Wireless Services'
secretary of the stockholder's intention to bring the business before the
meeting, may be conducted. Under these stockholder notice procedures, for notice
of stockholder nominations to be made at an annual meeting to be timely, the
notice must be received by AT&T Wireless Services' secretary not later than the
close of business on the 90th calendar day nor earlier than the close of
business on the 120th calendar day before the first anniversary of the
                                       128
<PAGE>   135

preceding year's annual meeting, except that, if the date of the annual meeting
is more than 30 calendar days before or more than 60 calendar days after such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the close of business on the 120th calendar day before the
annual meeting and not later than the close of business on the later of the 90th
calendar day before the annual meeting or the 10th calendar day following the
day on which public announcement of a meeting date is first made by us.

     Nevertheless, if the number of directors to be elected to AT&T Wireless
Services' board is increased and there is no public announcement by AT&T
Wireless Services naming all of the nominees for director or specifying the size
of our increased board at least 100 calendar days before the first anniversary
of the preceding year's annual meeting, a stockholder's notice also will be
considered timely, but only with respect to nominees for any new positions
created by the increase, if it shall be delivered not later than the close of
business on the 10th calendar day following the day on which the public
announcement is first made by AT&T Wireless Services. Under these stockholder
notice procedures, for notice of a stockholder nomination to be made at a
special meeting at which directors are to be elected to be timely, the notice
must be received by AT&T Wireless Services not earlier than the close of
business on the 120th calendar day before the special meeting and not later than
the close of business on the later of the 90th calendar day before the special
meeting or the 10th calendar day following the day on which public announcement
is first made of the date of the special meeting and of the nominees proposed by
AT&T Wireless Services' board to be elected at the meeting.

     In addition, under these stockholder notice procedures, a stockholder's
notice to us proposing to nominate a person for election as a director or
relating to the conduct of business other than the nomination of directors will
be required to contain some specified information. If the chairman of a meeting
determines that an individual was not nominated, or other business was not
brought before the meeting, in accordance with our stockholder notice procedure,
the individual will not be eligible for election as a director, or the business
will not be conducted at the meeting, as the case may be.

  AMENDMENT

     We expect that AT&T Wireless Services' charter will provide that the
affirmative vote of the holders of at least 80% of AT&T Wireless Services'
voting stock then outstanding, voting together as a single class, is required to
amend provisions of the charter relating to stockholder action; the number,
election and tenure of directors; the nomination of director candidates and the
proposal of business by stockholders; the filling of vacancies; and the removal
of directors. We expect AT&T Wireless Services' certificate to further provide
that the related by-laws described above, including the stockholder notice
procedure, may be amended only by the affirmative vote of a majority of the
whole board or by the affirmative vote of the holders of at least 80% of the
voting power of the outstanding shares of voting stock, voting together as a
single class.

RIGHTS AGREEMENT

     We expect that AT&T Wireless Services' board of directors will adopt a
rights agreement on or before the completion of the spin-off (the "Rights
Agreement"). Under the Rights Agreement, AT&T Wireless Services expects to issue
one preferred share purchase right for each outstanding share of AT&T Wireless
Services common stock. Each right will entitle the registered holder to purchase
from AT&T Wireless Services one one-hundredth of a share of Series A junior
participating preferred stock, par value $.01 per share, of AT&T Wireless
Services at a price of $       , subject to adjustment in some circumstances.
The description and terms of the rights will be set forth in a rights agreement
between AT&T Wireless Services and the designated rights agent. The description
set forth below is intended as a summary only and is qualified in its entirety
by reference to the form of the rights agreement, which will be filed as an
exhibit to the registration statement of which this document is a part.

                                       129
<PAGE>   136

     The rights will be evidenced by the certificates representing AT&T Wireless
Services common stock until the earlier to occur of:

     - 10 days following a public announcement that a person or group of
       affiliated or associated persons has acquired beneficial ownership of at
       least   % or more of the outstanding shares of AT&T Wireless Services
       common stock, or

     - 10 business days or a later date determined by our board following the
       commencement of, or announcement of an intention to make, a tender offer
       or exchange offer the consummation of which would result in the
       beneficial ownership by a person or group of   % or more of such
       outstanding shares of AT&T Wireless Services common stock (the
       "Distribution Date").

     We expect the Rights Agreement to provide that, until the Distribution Date
or earlier redemption or expiration of the rights, the rights will be
transferred with and only with AT&T Wireless Services common stock. Until the
Distribution Date or earlier redemption or expiration of the rights, AT&T
Wireless Services common stock certificates will contain a notation
incorporating the Rights Agreement by reference. As soon as practicable
following the Distribution Date, separate certificates evidencing the rights
will be mailed to holders of record of AT&T Wireless Services common stock as of
the close of business on the Distribution Date and the separate right
certificates alone will evidence the rights.

     The rights will not be exercisable until the Distribution Date. The rights
will expire on the 10th anniversary of the Rights Agreement, unless the final
expiration date is extended or unless the rights are earlier redeemed or
exchanged by us, in each case, as summarized below.

     In the event that any person or group of affiliated or associated persons
becomes an acquiring person, proper provision shall be made so that each holder
of a right, other than rights beneficially owned by the acquiring person which
will thereafter be void, will later have the right to receive upon exercise that
number of shares of AT&T Wireless Services common stock having a market value of
two times the exercise price of the right. If AT&T Wireless Services is acquired
in a merger or other business combination transaction or 50% or more of our
consolidated assets or earning power are sold after a person or group of
affiliated or associated persons becomes an acquiring person, proper provision
will be made so that each holder of a right will thereafter have the right to
receive, upon the exercise thereof at the then-current exercise price of the
right, that number of shares of common stock of the acquiring company which at
the time of the transaction will have a market value of two times the exercise
price of the right.

     At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of   % or more of AT&T Wireless
Services outstanding common stock and before the acquisition by the person or
group of   % or more of our outstanding common stock, AT&T Wireless Services'
board of directors may exchange the rights, other than rights owned by the
person or group which have become void, in whole or in part, at an exchange
ratio of one share of AT&T Wireless Services common stock, or one one-hundredth
of one of our junior preferred shares, or of a share of a class or series of
preferred stock having equivalent rights, preferences and privileges, per right
subject to adjustment.

     At any time before the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of   % or more of AT&T Wireless
Services' outstanding common stock, AT&T Wireless Services' board of directors
may redeem the rights in whole, but not in part, at a price of $.01 per right,
as adjusted. The redemption of the rights may be made effective at such time on
such basis and with such conditions as AT&T Wireless Services' board of
directors, in its sole discretion, may establish. Immediately upon any
redemption of the rights, the right to exercise the rights will terminate and
the only right that the holders of the rights will be eligible to receive will
be the redemption price.

     The terms of the rights may be amended by AT&T Wireless Services' board of
directors without the consent of the holders of the rights; provided, however,
that, our board may not reduce the threshold at which a person or group becomes
an acquiring person to below   % of our outstanding common stock and from and
after such time as any person or group of affiliated or associated persons
becomes an acquiring person, no amendment may adversely affect the interests of
the holders of the rights.

                                       130
<PAGE>   137

     Until a right is exercised, the holder of that right, as a holder, will
have no additional rights as an AT&T Wireless Services stockholder solely by
virtue of holding that right, including, without limitation, the right to vote
or to receive dividends.

     The number of outstanding rights and the number of one one-hundredths of
AT&T Wireless Services' junior preferred shares issuable upon exercise of each
right also will be subject to adjustment in the event of a stock split of AT&T
Wireless Services' common stock or a stock dividend on AT&T Wireless Services'
common stock payable in its common stock or subdivisions, consolidations or
combinations of common stock occurring, in any case, before the Distribution
Date.

     The purchase price payable, and the number of AT&T Wireless Services'
junior preferred shares or other securities or property issuable, upon exercise
of the rights will be subject to adjustment from time to time to prevent
dilution:

     - in the event of a stock dividend on, or a subdivision, combination or
       reclassification of, our junior preferred shares;

     - upon the grant to holders of our junior preferred shares of some rights
       or warrants to subscribe for or purchase our junior preferred shares at a
       price, or securities convertible into our junior preferred shares with a
       conversion price, less than the then-current market price of our junior
       preferred shares; or

     - upon the distribution to holders of our junior preferred shares of
       evidences of indebtedness or assets excluding regular periodic cash
       dividends paid out of earnings or retained earnings or dividends payable
       in our junior preferred shares or of subscription rights or warrants
       other than those referred to above.

     With some exceptions, no adjustment in the purchase price will be required
until cumulative adjustments require an adjustment of at least one percent in
the purchase price. No fractional junior preferred shares will be issued, other
than fractions which are integral multiples of one one-hundredth of one of our
junior preferred shares, which may, at our election, be evidenced by depositary
receipts and instead, an adjustment in cash will be made based on the market
price of our junior preferred shares on the last trading day before the date of
exercise.

     AT&T Wireless Services' junior preferred shares purchasable upon exercise
of the rights will not be redeemable. Each of AT&T Wireless Services' junior
preferred shares will be entitled to a minimum preferential quarterly dividend
payment of $1.00 per share but will be entitled to an aggregate dividend of 100
times the dividend declared per share of common stock. In the event of
liquidation, the holders of AT&T Wireless Services' junior preferred shares will
be entitled to a minimum preferential liquidation payment of $100 per share but
will be entitled to an aggregate payment of 100 times the payment made per share
of common stock. Each of AT&T Wireless Services' junior preferred shares will
have 100 votes voting together with our common stock. Finally, in the event of
any merger, consolidation or other transaction in which shares of common stock
are exchanged, each one of AT&T Wireless Services' junior preferred shares will
be entitled to receive 100 times the amount received per one share of common
stock. These rights are protected by customary anti-dilution provisions.

     Due to the nature of AT&T Wireless Services' junior preferred shares'
dividend, liquidation and voting rights, the value of the one one-hundredth
interest in one of AT&T Wireless Services' junior preferred shares purchasable
upon exercise of each right should approximate the value of one share of common
stock.

     The rights have anti-takeover effects. The rights will cause substantial
dilution to a person or group of persons that attempts to acquire us on terms
not approved by AT&T Wireless Services' board of directors. The rights should
not interfere with any merger or other business combination approved by AT&T
Wireless Services' board before the time that a person or group has acquired
beneficial ownership of   % percent or more of the common stock since the rights
may be redeemed by us at the redemption price until such time.

     We expect the terms of the Rights Agreement to contain certain exceptions
for DoCoMo's investment in AT&T Wireless Services.

DELAWARE BUSINESS COMBINATION STATUTE

     Section 203 of the DGCL provides that, subject to some exceptions, an
interested stockholder of a Delaware corporation shall not engage in any
business combination, including mergers or consolidations or acquisitions of
additional shares of the corporation, with the corporation for a three-year
period following the date that such stockholder becomes an interested
stockholder unless:

     - before the date of the business combination, the board of directors of
       the corporation approved either the business combination or the
       transaction which resulted in the stockholder becoming an interested
       stockholder;

     - upon consummation of the transaction which resulted in the stockholder
       becoming an "interested stockholder," the interested stockholder owned at
       least 85% of the voting stock of the corporation outstanding at the time
       the transaction commenced, excluding some shares; or

     - on or subsequent to such date, the business combination is approved by
       the board of directors of the corporation and authorized at an annual or
       special meeting of stockholders by the affirmative vote of at least
       66 2/3% of the outstanding voting stock which is not owned by the
       interested stockholder. Except as otherwise specified in Section 203, an
       interested stockholder is defined to include:

      - any person that is the owner of 15% or more of the outstanding voting
        stock of the corporation, or is an affiliate or associate of the
        corporation and was the owner of 15% or more of the outstanding voting
        stock of the corporation at any time within three years immediately
        before the date of determination; and

      - the affiliates and associates of the stockholder.

     Under some circumstances, Section 203 makes it more difficult for a person
who would be an interested stockholder to effect various business combinations
with a corporation for a three-year period. We have not elected to be exempt
from the restrictions imposed under Section 203. However AT&T and its affiliates
are excluded from the definition of interested stockholder for purposes of
Section 203. The provisions of Section 203 may encourage persons interested in
acquiring us to negotiate in advance with our board, since the stockholder
approval requirement would be avoided if a majority of the directors then in
office approves either the business combination or the transaction which results
in any person becoming an interested stockholder. These provisions also may have
the effect of preventing changes in our management. It is possible that these
provisions could make it more difficult to accomplish transactions which our
stockholders may otherwise deem to be in their best interests.

OTHER COMPANIES RESULTING FROM AT&T'S RESTRUCTURING PLAN

     You should also note, although we have not yet made any determination, it
is possible that the charter, by-laws and other constituent documents of the
other companies created by AT&T's restructuring plan will also contain
provisions that could delay or prevent a change of control that you may favor.

                 MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

IN GENERAL

     All shareholders should consult their own tax advisors concerning the tax
consequences of this exchange offer and of the mandatory exchange of AT&T
Wireless Services common stock for AT&T Wireless Group tracking stock in light
of their particular circumstances. This summary is of a general nature only and
is not intended to be, nor should it be construed to be, legal or tax advice to
any particular investor.

     We summarize below the material U.S. federal income tax consequences
relating to this exchange offer. The summary is based on the Internal Revenue
Code, the Treasury regulations promulgated thereunder and interpretations of the
Code and Treasury regulations by the courts and the IRS, all as they exist as of
the date of this document and all of which are subject to change at any time,
possibly with retroactive effect. Any such change could alter the tax
consequences to AT&T or the holders of AT&T common stock as described below. See
"Risk Factors -- Risk Factors Relating to AT&T's Corporate Structure prior to
the Spin-Off -- Changes in the tax law or in the interpretation of current tax
law may result in redemption of AT&T Wireless Group tracking stock or cessation
of the issuance of further shares."

     It is a condition to the mandatory exchange of AT&T Wireless Services
common stock for AT&T Wireless Group tracking stock that AT&T has obtained a
private letter ruling from the Internal Revenue Service which confirms, among
other things, that the distribution by AT&T of the common stock of AT&T Wireless
Services to holders of AT&T Wireless Group tracking stock will qualify as a
tax-free spin-off to AT&T and its shareholders under Section 355 of the Code. To
the extent this summary describes the federal income tax consequences of the
mandatory exchange to AT&T and its shareholders, such consequences are expected
to be set forth in the IRS ruling.

     This summary does not discuss all tax considerations that may be relevant
to shareholders in light of their particular circumstances, nor does it address
the consequences to shareholders subject to special treatment under the U.S.
federal income tax laws, such as tax-exempt entities, non-resident alien
individuals, foreign entities, foreign trusts and estates and beneficiaries
thereof, persons who acquire such AT&T common stock pursuant to the exercise of
employee stock options or otherwise as compensation, insurance companies, and
dealers in securities. In addition, this summary does not address the U.S.
federal income tax consequences to shareholders who do not hold their common
stock or AT&T Wireless Group tracking stock as a capital asset. This summary
does not address any state, local or foreign tax consequences.

U.S. FEDERAL INCOME TAX CONSEQUENCES

     The exchange and mandatory exchange will have the U.S. federal income tax
consequences set forth below to holders of AT&T common stock, holders of AT&T
Wireless Group tracking stock, and AT&T only if AT&T Wireless Group tracking
stock is treated as stock of AT&T for U.S. federal income tax purposes. If the
exchange of AT&T Wireless Group tracking stock for AT&T common stock or the
mandatory exchange of AT&T Wireless Services common stock for AT&T Wireless
Group tracking stock were held to be taxable, AT&T and the exchanging
shareholders potentially would incur material tax liabilities.

     Exchange Offer

     Subject to the discussion below relating to the receipt of cash instead of
fractional shares, for U.S. federal income tax purposes the tax consequences of
the exchange of AT&T Wireless Group tracking stock for AT&T common stock are as
follows:

     - no gain or loss will be recognized by, and no amount will be included in
       the income of, shareholders upon their receipt of shares of AT&T Wireless
       Group tracking stock in this exchange offer;

     - for shareholders that surrender shares of AT&T common stock in this
       exchange offer, the aggregate tax basis of the shares of AT&T Wireless
       Group tracking stock received by the shareholders pursuant to this
       exchange offer will be the same as the aggregate tax basis of the shares
       of AT&T common stock exchanged in this exchange offer; and
                                       133
<PAGE>   140

     - the aggregate tax basis of the shares of AT&T common stock retained by
       such shareholders will remain unchanged;

     - the holding period of the shares of AT&T Wireless Group tracking stock
       received by the shareholders in this exchange offer will include the
       holding period of the shares of AT&T common stock with respect to which
       the shares of AT&T Wireless Group tracking stock were received;

     - no gain or loss will be recognized by, and no amount will be included in
       the income of, AT&T upon issuance of the shares of AT&T Wireless Group
       tracking stock in exchange for shares of AT&T common stock in this
       exchange offer.

     Mandatory Exchange

     Subject to the discussion below relating to the receipt of cash instead of
fractional shares, and assuming receipt of the private letter ruling from the
Internal Revenue Service, for U.S. federal income tax purposes the tax
consequences of the mandatory exchange are as follows:

     - no gain or loss will be recognized by, and no amount will be included in
       the income of, shareholders upon their receipt of shares of AT&T Wireless
       Services common stock in the mandatory exchange;

     - the aggregate tax basis of the shares of AT&T Wireless Services common
       stock received by shareholders in the mandatory exchange will be the same
       as the aggregate tax basis of the shares of AT&T Wireless Group tracking
       stock exchanged therefor;

     - the holding period of the shares of AT&T Wireless Services common stock
       received by shareholders in the mandatory exchange will include the
       holding period of the shares of AT&T Wireless Group tracking stock with
       respect to which the shares of AT&T Wireless Services common stock were
       received;

     - no gain or loss will be recognized by, and no amount will be included in
       the income of, AT&T upon the issuance of AT&T Wireless Services common
       stock in exchange for AT&T Wireless Group tracking stock.

     - Current Treasury Regulations require each holder of AT&T Wireless Group
       tracking stock who receives AT&T Wireless Services, Inc. common stock
       pursuant to the mandatory exchange to attach to his or her federal income
       tax return for the year in which the mandatory exchange occurs, a
       detailed statement setting forth such data as may be appropriate in order
       to show the applicability of Section 355 of the Code to the mandatory
       exchange. AT&T will provide the appropriate information to each
       shareholder of record.

     Receipt of Cash Instead of Fractional Shares

     No fractional shares of AT&T Wireless Group tracking stock will be issued
to shareholders who participate in this exchange offer and no fractional shares
of AT&T Wireless Services common stock will be issued in the mandatory exchange.
All fractional shares resulting from this exchange offer or from the mandatory
exchange will be aggregated and sold by the exchange agent and the proceeds will
be distributed to the owners of such fractional shares.

     Cash received by an exchanging stockholder instead of a fractional share
interest will be treated as having been received in exchange for such fractional
share interest, and gain or loss will generally be recognized for U.S. federal
income tax purposes. This gain or loss will be measured by the difference
between the amount of cash received and the portion of such stockholder's tax
basis allocable to such fractional share interest. Such gain or loss will be
treated as capital gain or loss. For taxpayers who are individuals, if their
fractional share interest has a holding period for U.S. federal income tax
purposes of more than one year, any gain will generally be subject to a stated
maximum rate of 20%. In general, for purposes of the exchange offer, a person's
holding period for a fractional share interest will include the period during
which such person held the AT&T common stock with respect to which such
fractional share interest was received. For purposes of the mandatory exchange,
a person's holding period for a fractional share interest will include the
period during
                                       134
<PAGE>   141

which such person held the AT&T common stock and the period during which such
person held the AT&T Wireless Group tracking stock with respect to which such
fractional share interest was received.

     Under the Code, if you receive cash in lieu of a fractional share interest,
you may be subject, under certain circumstances, to backup withholding at a 31%
rate with respect to such cash unless you provide proof of an applicable
exemption or a correct taxpayer identification number, and otherwise comply with
applicable requirements of the backup withholding rules. The letter of
transmittal provides instructions on how to provide us with information to
prevent backup withholding with respect to cash received in the exchange offer
in lieu of a fractional share interest. Any amounts withheld under the backup
withholding rules are not an additional tax and may be refunded or credited
against your U.S. federal income tax liability, provided you furnish the
required information to the IRS.

     Holders who have blocks of AT&T common stock with different per share tax
bases are urged to consult their tax advisors regarding the possible tax basis
consequences to them of this exchange offer and mandatory exchange.

                                 LEGAL MATTERS

     The validity of the AT&T Wireless Group tracking stock offered in this
exchange offer will be passed upon for AT&T by Robert S. Feit, Esq., General

this exchange offer will be passed upon for AT&T by Wachtell, Lipton, Rosen &

                              AT&T WIRELESS GROUP

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The unaudited pro forma condensed combined balance sheet set forth below as
of September 30, 2000 for AT&T Wireless Group gives effect to (1) the DoCoMo
transaction described below and (2) the repayment of all intercompany
obligations owed to AT&T using available funds, including long-term debt and
preferred stock outstanding as of September 30, 2000 as if such events had been
completed on January 1, 1999. The unaudited pro forma condensed statements of
operations assume that AT&T Wireless Group had incurred interest expense
associated with an assumed amount of long-term debt outstanding equal to the
combined amount of intercompany long-term debt and preferred stock held by AT&T
for both the nine months ended September 30, 2000 and for the year ended
December 31, 1999. AT&T Wireless Group has no commitments related to future
financing arrangements, however, interest expense has been reflected on these
intercompany amounts in the combined statements of operations which is more
reflective of AT&T Wireless Group results than reflecting no interest expense or
preferred stock dividends for these periods.

     DoCoMo will invest approximately $9.8 billion for AT&T preferred stock,
equivalent to 406 million shares of AT&T Wireless Group tracking stock (a 16%
economic interest). AT&T will reduce its retained interest in AT&T Wireless
Group by 178 million shares and will receive $20.50 per share from DoCoMo. The
balance of the 406 million shares will come from the issuance of 228 million new
primary shares of AT&T Wireless Group tracking stock at $27 per share, which
will be attributed to AT&T Wireless Group in the form of cash. In addition,
DoCoMo will acquire 5-year warrants to purchase the equivalent of an additional
41.7 million shares of AT&T Wireless Group tracking stock at $35 per share. The
Convertible Preferred Stock held by DoCoMo will convert into AT&T Wireless Group
tracking stock immediately prior to the distribution of AT&T Wireless.

     There is no impact to AT&T Wireless Group's combined financial statements
as a result of this exchange offer.

     The distribution of AT&T Wireless Services will result in a non-recurring
compensation charge associated with the remeasurement of AT&T Wireless Group
stock options held by current and former employees of AT&T. The charge will be
recorded by AT&T Wireless Services immediately after the separation from AT&T.
The compensation charge for the AT&T Wireless stock options held by non-AT&T
Wireless employees will be measured using the Black-Scholes option pricing
model.

     Based on stock price assumptions of $20 per share for both AT&T and AT&T
Wireless Group and historical company and industry stock price volatility the
estimated range of pretax compensation expense for AT&T Wireless at distribution
is approximately $400 million - $500 million related to the AT&T Wireless
options held by non-AT&T Wireless employees. This fair value calculation is
significantly affected by the stock price at the time of separation. For
example, given an AT&T Wireless Group tracking stock price between $15 and $25
per share, the pre-tax compensation expense could change by an amount between
$40-$60 million for a $1 change in share price. Due to the fact that the charge
is a one-time event, its effects have not been included as a pro forma
adjustment to the income statement or balance sheet.

     In connection with the assumption by AT&T Wireless Services of the
obligation for the AT&T employees that hold AT&T Wireless stock options and
other employee obligations, AT&T will reduce its retained inter-group interest
in AT&T Wireless Group by approximately 12.6 million nominal shares of AT&T
Wireless Group tracking stock.

     The pro forma adjustments included herein are based on available
information and certain assumptions that management believes are reasonable and
are described in the accompanying notes to the pro forma financial statements.
The unaudited pro forma financial statements do not necessarily represent what
AT&T Wireless Group's financial position or results of operations would have
been had these events occurred on such dates or to project AT&T Wireless Group's
financial position or results of operations at or for any future date or period.
In the opinion of management, all adjustments necessary to present fairly the
unaudited pro forma financial information have been made. The unaudited pro
forma financial statements should be read in conjunction with the historical
financial statements of AT&T and AT&T Wireless Group, incorporated by reference
herein.

      NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. This column reflects the historical combined results of operations and
   financial position of AT&T Wireless Group.

2. Gives effect to the proceeds to be attributed to AT&T Wireless Group as a
   result of the investment in AT&T Wireless Group by DoCoMo. AT&T will receive
   $9.8 billion from DoCoMo in conjunction with the sale of AT&T Wireless Group
   preferred stock and warrants. AT&T will allocate $6.2 billion to AT&T
   Wireless Group.

3. Gives effect to the repayment of outstanding intercompany debt and preferred
   stock owed to AT&T as of September 30, 2000, in accordance with the terms of
   the separation and distribution agreement to be entered into between AT&T and
   AT&T Wireless Services.

4. Gives effect to the assumption that AT&T Wireless Group had long-term debt
   outstanding for both the year ended December 31, 1999 and the nine months
   ended September 30, 2000 in an amount equal to the total intercompany
   indebtedness owed to AT&T. These intercompany amounts are assumed to be
   repaid as of January 1, 1999 for balance sheet purposes using available
   funds. AT&T Wireless Group has no commitments related to future financing
   arrangements, however interest expense has been reflected on these
   intercompany amounts in the combined statements of operations which is more
   reflective of AT&T Wireless Group results. The interest expense has been
   calculated utilizing the stated rate of 8.1% on the intercompany debt, which
   differs from the cumulative preferred rate of 9.0%.

5. Reflects the federal statutory and blended state tax effect on the pro forma
   adjustments.

                         UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS

     The unaudited pro forma financial statements set forth below for AT&T give
effect to (1) the AT&T Wireless Group Exchange Offer, (2) the DoCoMo transaction
and (3) the AT&T Wireless Group distribution (collectively, the AT&T wireless
events), as if such events had been completed on January 1, 1999 for income
statement purposes, and at September 30, 2000 for balance sheet purposes,
subject to the assumptions and adjustments in the accompanying notes to the pro
forma financial statements. The unaudited pro forma financial statements set
forth below for AT&T also give effect to the TCI and MediaOne mergers as if they
had been completed on January 1, 1999 for income statement purposes. Upon
receipt of necessary approvals, AT&T will report the AT&T Wireless Group as a
Discontinued Operation, in accordance with APB Opinion No. 30 "Reporting the
Results of Operations - Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions" (APB 30). For accounting purposes, the spin-off/split-off (the
"distribution") of the AT&T Wireless Group is a non pro-rata distribution and is
to be recorded at fair value resulting in the recognition of a gain on the
remaining AT&T entity upon the distribution date. Such gain is reflected in
AT&T's equity in the unaudited pro forma balance sheet at September 30, 2000.
See the Notes to the Unaudited Pro Forma Financial Statements for additional
disclosure of potential material nonrecurring charges and credits directly
attributable to the events as noted above which are not reflected in the pro
forma financial statements.

     The pro forma adjustments included herein are based on available
information and certain assumptions that management believes are reasonable and
are described in the accompanying notes to the pro forma financial statements.
The unaudited pro forma financial statements do not necessarily represent what
AT&T's financial position or results of operations would have been had the TCI
or MediaOne mergers or the AT&T wireless events occurred on such dates or to
project AT&T's financial position or results of operations at or for any future
date or period. In the opinion of management, all adjustments necessary to
present fairly the unaudited pro forma financial information have been made. The
unaudited pro forma financial statements should be read in conjunction with the
historical financial statements of AT&T and the AT&T Wireless Group, both
incorporated by reference herein.

     DoCoMo will invest approximately $9.8 billion for AT&T preferred stock,
equivalent to 406 million shares of AT&T Wireless tracking stock (a 16% economic
interest). AT&T will reduce its retained interest in the AT&T Wireless Group by
178 million shares and will receive $20.50 per share from DoCoMo. The balance of
the 406 million shares will come from the issuance of 228 million new primary
shares of AT&T Wireless Group tracking stock at $27 per share. In addition,
DoCoMo will acquire 5-year warrants to purchase the equivalent of an additional
41.7 million shares of AT&T Wireless Group tracking stock at $35 per share. The
convertible preferred stock held by DoCoMo will convert into AT&T Wireless Group
tracking stock immediately prior to the distribution of AT&T Wireless Services.

     AT&T closed its merger with MediaOne on June 15, 2000, therefore, MediaOne
is reflected in the September 30, 2000 balance sheet. The merger was accounted
for using the purchase method of accounting. Accordingly, AT&T has established a
new basis for MediaOne Group's assets and liabilities using their preliminarily
assigned fair values based on the allocation of the purchase price including the
costs of the merger. We may make refinements to the allocation of the purchased
price in future periods as the related fair value appraisals of certain assets
and liabilities are finalized.

     AT&T closed its merger with TCI on March 9, 1999, therefore, TCI is
reflected in the September 30, 2000 balance sheet. The merger was accounted for
using the purchase method of accounting. Accordingly, AT&T has established a new
basis for TCI's assets and liabilities using their assigned fair values based on
the allocation of the purchase price including the costs of the merger. In
connection with the merger, AT&T issued a separate tracking stock to reflect the
economic performance of Liberty Media Group, TCI's former programming and
technology investment businesses.

     On April 27, 2000, AT&T completed an initial public offering of a tracking
stock (AT&T Wireless Group tracking stock) representing a 15.6% interest in the
AT&T Wireless Group. The results of AT&T Wireless Group are included in their
entirety in the consolidated results of AT&T. The earnings available to Common
Shareholders are (reduced) increased by the 15.6% of (income) loss from the AT&T
Wireless Group beginning on April 27, 2000, the date of formation of the AT&T
Wireless Group Tracking Stock.

     In connection with the assumption by AT&T Wireless Services of the
obligation for the AT&T employees that hold AT&T Wireless stock options and
other employee obligations, AT&T will reduce its retained inter-group interest
in AT&T Wireless Group by approximately 12.6 million nominal shares of AT&T
Wireless Group tracking stock.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     1. These columns reflect the historical results of operations and financial
position of the respective companies.

     2. This column reflects the deconsolidation of the historical results of
operations for the interests represented by the shares of Liberty Media Group
tracking stock for the period January 1, 1999 through February 28, 1999. AT&T
accounts for the Liberty Media Group under the equity method because it does not
possess a "controlling financial interest" for financial accounting purposes in
the Liberty Media Group.

     3. This column reflects the TCI merger purchase accounting adjustments.
These adjustments include the amortization of the excess of the purchase price
over the net assets acquired and incremental interest expense on additional
borrowings for the period January 1, 1999 through February 28, 1999.

     4. This column reflects the MediaOne merger purchase accounting
adjustments. These adjustments include the amortization of the excess of the
purchase price over the net assets acquired, incremental interest expense on
additional borrowings and the elimination of a non-recurring charge related to
the termination of MediaOne's merger with Comcast Corp.

     5. These entries give effect to an assumed approximate $10 billion exchange
of 563 million shares of AT&T Wireless Group tracking stock for 528 million
shares of AT&T common stock offered to existing AT&T common stock shareholders.
The number of shares exchanged is calculated based on the relative fair values
as of December 20, 2000, for pro forma purposes, in order to effectuate an equal
market value exchange. The exchange offer, as presented, reflects a reduction of
24.4% economic interest in the AT&T Wireless Group currently held by the AT&T
Common Stock Group. As a result of the exchange offer, the earnings per share
calculation of the AT&T Common Stock Group reflects a decrease in the number of
outstanding shares of AT&T common stock and decrease in net income attributable
to the AT&T Common Stock Group as a result of the decrease in the economic
interest in the AT&T Wireless Group held by the AT&T Common Stock Group (for the
period subsequent to April 27, 2000). The effect of the exchange offer on the
balance sheet would include: 1) a decrease in the par and additional
paid-in-capital of AT&T common stock and 2) an increase in the par and
additional paid-in-capital of AT&T Wireless Group tracking stock. Since the
number of shares of AT&T Wireless Group tracking stock and the net income
attributable to the AT&T Wireless Group will increase proportionally, there will
be no change to the calculated earnings per share for the AT&T Wireless Group.
For purposes of these pro forma financial statements, it is assumed that the
fair value of the exchange is based on the closing price of AT&T Wireless Group
tracking stock on December 20, 2000. There is no gain or loss on the exchange
offer. The pro forma financial statements do not reflect any premium on the
exchange as the Board of Directors of AT&T has not approved a fixed premium at
this time for this exchange offer. However, if a premium is necessary to
facilitate the exchange, such premium will be recorded as a reduction to net
income attributable to the AT&T Common Stock Group and result in an additional
decrease in the economic interest in the AT&T Wireless Group held by the AT&T
Common Stock Group. Assuming a 5% premium in connection with the exchange offer,
the diluted earnings per share attributable to the AT&T Common Stock Group would
be $1.61 and $2.61 for the nine months ended September 30, 2000 and the year
ended December 31, 1999, respectively. Each 1% change in the premium would
result in an impact to diluted earnings per share of approximately $.03.

     6. These entries reflect the sale of the preferred stock and warrants to
DoCoMo for $9.811 billion. The preferred stock is characterized as a mandatorily
redeemable preferred security, as defined by the SEC in Accounting Series
Release (ASR) No. 268, and is classified outside of stockholders' equity on the
balance sheet. The value of the warrants is recorded as a liability and will be
marked to market in subsequent periods through its period of expiration. The
values assigned to the preferred stock ($9.547 billion) and the warrants ($264
million) are based upon an allocation of the relative fair values of each
instrument. The proceeds from the sale will be allocated among AT&T and the AT&T
Wireless Group with $3.652 billion being utilized by AT&T to pay down short-term
debt and the remaining $6.159 billion allocated to the AT&T Wireless Group. The
pay down in short-term debt would result in a reduction in interest expense, of
$265 million ($164 million, net of taxes) for the year ended December 31, 1999
and $199 million ($123 million, net of taxes) for the nine

                                      F-12
<PAGE>   155

months ended September 30, 2000, respectively. The reduction in interest expense
was calculated using an interest rate of 7.25%, which reflects the current
90-day commercial paper rate.

     7. This entry reflects the fair value adjustment for accounting purposes
that result in a gain which will be recorded upon the distribution of the AT&T
Wireless Group. This distribution is non pro-rata due to the alteration of
shareowner interests in the AT&T Wireless Group as a result of the exchange
offer. For this reason, the distribution will be accounted for at fair value and
will result in a nonrecurring gain upon distribution equal to the excess of the
fair value of the securities issued over AT&T's carrying value of the net assets
of the AT&T Wireless Group. The actual gain will be determined upon
distribution. Due to the fact that the gain is a one-time event, its effects
have not been included as a pro forma adjustment to the income statement;
however, it has been included as a pro forma adjustment to retained earnings on
the pro forma balance sheet. The estimated gain is calculated as follows
(numbers in millions):

     8. The adjustments presented deduct the historical results of operations
and the historical financial position of the AT&T Wireless Group to reflect the
distribution of the AT&T Wireless Group from AT&T. The distribution is a fair
value transaction and as such the fair value of the net assets has been recorded
as a reduction to retained earnings for the stock dividend of AT&T's retained
Inter-Group interest and par and additional paid-in-capital for the distribution
to the AT&T Wireless Group tracking stock Shareholders. The reduction to
retained earnings and the reduction to additional paid in capital is calculated
as follows: (Amounts in millions)

     In addition, to the historical adjustments, other adjustments relating to
the DoCoMo transaction have been presented. These adjustments reflect that $6.2
billion of cash associated with the transaction has been allocated to the AT&T
Wireless Group, the preferred stock associated with the transaction is converted
to 406 million shares of AT&T Wireless Group Tracking Stock and the warrants
associated with the transaction are converted to warrants in AT&T Wireless
Services.

     9. These adjustments reflect the cash received by AT&T from AT&T Wireless
Group in connection with the repayment of the $1.8 billion intercompany loan and
the $3.0 billion preferred stock (together, "intercompany indebtedness"). The
repayment of intercompany indebtedness is contained in the preliminary
Separation and Distribution Agreement between AT&T and AT&T Wireless Group. It
is assumed that AT&T utilized the proceeds it received from AT&T Wireless Group
to pay down its short-term debt in the pro forma balance sheet. The paydown in
short-term debt would result in a reduction in interest expense of $348 million
($215 million net of taxes), for the year ended December 31, 1999 and $261
million ($161 million net of taxes) for the nine months ended September 30,
2000, respectively. The reduction in interest expense was calculated using an
interest rate of 7.25% which reflects the current 90-day commercial paper rate.

the separate financial statements of AT&T after excluding the AT&T Wireless
Group on a pro forma basis that were eliminated in the AT&T consolidated
financial statements and were therefore not reflected in AT&T's historical
results and financial position.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Pursuant to the statutes of the State of New York, a director or officer of
a corporation is entitled, under specified circumstances, to indemnification by
the corporation against reasonable expenses, including attorneys' fees, incurred
by him or her in connection with the defense of a civil or criminal proceeding
to which he or she has been made, or threatened to be made, a party by reason of
the fact that he or she was such a director or officer. In certain
circumstances, indemnity is provided against judgments, fines and amounts paid
in settlement. In general, indemnification is available where the director or
officer acted in good faith, for a purpose such director or officer reasonably
believed to be in the best interests of the corporation. Specific court approval
is required in some cases. The foregoing statement is qualified in its entirety
by reference to Sections 715, 717 and 721 through 725 of the New York Business
Corporation Law (the "NYBCL").

     The by-laws of AT&T Corp. (the "Registrant") provide that the Registrant is
authorized, by (i) a resolution of shareholders, (ii) a resolution of directors
or (iii) an agreement providing for such indemnification, to the fullest extent
permitted by applicable law, to provide indemnification and to advance expenses
to its directors and officers in respect of claims, actions, suits, or
proceedings based upon, arising from, relating to, or by reason of the fact that
any such director or officer serves or served in such capacity with the
Registrant or at the request of the Registrant in any capacity with any other
enterprise.

     The Registrant has entered into contracts with its officers and directors,
pursuant to the provisions of Section 721 of the NYBCL, by which it will be
obligated to indemnify such persons, to the fullest extent permitted by the
NYBCL, against expenses, fees, judgments, fines, and amounts paid in settlement
in connection with any present or future threatened, pending or completed
action, suit or proceeding based in any way upon or related to the fact that
such person was an officer or director of the Registrant or, at the request of
the Registrant, an officer, director or other partner, agent, employee, or
trustee of another enterprise. The contractual indemnification so provided will
not extend to any situation where a judgment or other final adjudication adverse
to such person establishes that his acts were committed in bad faith or were the
result of active and deliberate dishonesty or that there inured to such person a
financial profit or other advantage.

     The directors and officers of the Registrant are covered by insurance
policies indemnifying them against certain liabilities, including certain
liabilities arising under the Securities Act of 1933, as amended, which might be
incurred by them in such capacities.

ITEM 22.  UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 20, or otherwise, the
Registrant has been advised that in the opinion of the SEC, such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally

                                      II-2
<PAGE>   160

prompt means. This includes information contained in documents filed subsequent
to the effective date of the registration statement through the date of
responding to the request. The undersigned Registrant hereby further undertakes
to supply by means of a post-effective amendment all information concerning a
transaction and the company being acquired involved therein, that was not the
subject of and included in the registration statement when it became effective.

     The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement.

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes
        in volume and price represent no more than a 20 percent change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table if the effective Registration Statement; and

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the registration
        statement.

     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in the Registration
Statement shall be deemed to be a new Registration Statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide thereof.

     The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X are not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.
