                          SUMMARY OF THE TRANSACTION

     This prospectus relates to up to 52,347,844 shares of AT&T common stock to
be issued in connection with the redemption or exchange of shares of Class A
preferred stock of TCI Pacific.

     Each holder of Class A preferred stock, at his or her option, may exchange
each of his or her shares of Class A preferred stock for 8.365 shares of AT&T
common stock.

     We may call all shares of Class A preferred stock for redemption on a date
to be set forth in a prospectus supplement to this prospectus. We reserve the
right not to proceed with the redemption prior to the actual delivery of the
notice of redemption.

     If we call the shares of Class A preferred stock for redemption, each share
of Class A preferred stock outstanding on the redemption date will be redeemed
for either cash or shares of AT&T common stock (or a combination thereof), as
determined by TCI Pacific, having a value calculated pursuant to the Restated
Certificate of Incorporation of TCI Pacific, including accrued and unpaid
dividends. The type of consideration and amount payable on redemption will be
set forth in a prospectus supplement to this prospectus. Dividends on shares of
Class A preferred stock will cease to accrue on the redemption date.

     The exchange privilege will terminate immediately prior to the close of
business on the redemption date. Accordingly, holders of shares of Class A
preferred stock who wish to exchange their shares for 8.365 shares of AT&T
common stock per share of Class

                                      -3-



A preferred stock must do so prior to the close of business on the redemption
date. Otherwise the right to exchange will terminate and holders who do not
exchange their shares will only receive the cash or shares of AT&T common stock
(or a combination thereof) payable in connection with the redemption. The
prospectus supplement will specify whether holders of shares of Class A
preferred stock will be entitled pursuant to the TCI Pacific Restated
Certificate of Incorporation to any accrued dividends upon exchange.

                              RECENT DEVELOPMENTS

     On December 19, 2001, AT&T and AT&T Broadband Corp., a wholly owned
subsidiary of AT&T, entered into a Separation and Distribution Agreement
providing, subject to the terms and conditions thereof, that AT&T would separate
its broadband business from its other businesses, transfer its broadband
business to AT&T Broadband and distribute shares of common stock of AT&T
Broadband to shareholders of AT&T. Also, on that day, AT&T, AT&T Broadband and
Comcast Corporation entered into a Merger Agreement pursuant to which, subject
to the terms and conditions thereof, AT&T Broadband would combine with Comcast
and shareholders of AT&T Broadband would receive shares of the combined entity
in exchange for their shares of AT&T Broadband. AT&T agreed under the Merger
Agreement to complete the redemption of the Class A preferred stock before the
merger is consummated. For additional information about these transactions, see
"Where You Can Find More Information."

     AT&T also announced that it intends to proceed with other aspects of its
previously announced restructuring, including the creation of a tracking stock
for its consumer services unit, which is expected, subject to shareholder
approval and other conditions, to be distributed to AT&T shareholders later this
year.

                                     EXPERTS

     The audited financial statements incorporated in this
prospectus/Registration Statement on Amendment No.3 to Form S-3 by reference to
AT&T's Current Report on Form 8-K, filed on September 24, 2001, except as they
relate to Liberty Media Group, have been audited by PricewaterhouseCoopers LLP,
independent accountants (and insofar as they relate to Liberty Media Group, by
KPMG LLP, independent accountants), whose reports thereon are incorporated by
reference. Such financial statements have been incorporated by reference in
reliance on the reports of such independent accountants, given on the authority
of such firms as experts in auditing and accounting.


     The combined financial statements of AT&T Wireless Group incorporated in
this prospectus/Registration Statement on Amendment No.3 to Form S-3 by
reference to AT&T's Annual Report on Form 10-K, filed on April 2, 2001 (as
amended on April 17, 2001), and the Current Report on Form 8-K, filed on March
29, 2001 (as amended on April 11, 2001) have been so incorporated in reliance on
the report of PricewaterhouseCoopers LLP, independent accountants, given on the
authority of said firm as experts in auditing and accounting.

      The combined balance sheets of Liberty Media Group ("New Liberty or

periods) which appear as an exhibit to the Annual Report on Form 10-K/A, dated
April 17, 2001, of AT&T, have been incorporated by reference herein in reliance
upon the report, dated February 26, 2001, of KPMG LLP, independent certified
public accountants, incorporated by reference herein, and upon the authority of

financial statements of AT&T.

     In addition, the KPMG LLP report contains an explanatory paragraph that
states that, effective March 9, 1999, AT&T, the owner of the assets comprising
New Liberty, acquired Tele-Communications, Inc., the owner of the assets
comprising Old Liberty, in a business combination accounted for as a purchase.
As a result of the acquisition, the combined financial information for the
periods after the acquisition is presented on a

                                      -7-



different cost basis than that for the periods before the acquisition and,
therefore, is not comparable.

subsidiaries as of December 31, 1998 and 1997, and the related consolidated
statements of operations and comprehensive earnings, stockholders' equity, and
cash flows for each of the years in the three-year period ended December 31,

Item 15. 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 attorney's fees, incurred
by him/her in connection with the defense of a civil or criminal proceeding to
which he/she has been made, or threatened to be made, a party by reason of the
fact that he/she was such 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 he/she reasonably believed to be in the best interests
of the corporation. Specific court approval is required in some cases. The
foregoing statement is subject to the detailed provisions of Sections 715, 717
and 721-725 of the New York Business Corporation Law.

     The AT&T By-laws provide that AT&T 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 AT&T or at the request of AT&T in any capacity with
any other enterprise.

     AT&T has entered into contracts with its officers and directors, pursuant
to the provisions of New York Business Corporation Law Section 721, by which it
will be obligated to indemnify such persons, to the fullest extent permitted by
the New York Business Corporation Law, 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 AT&T
or, at the request of AT&T, 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/her acts were committed
in


                                      II-1



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 AT&T are covered by insurance policies
indemnifying against certain liabilities, including certain liabilities arising
under the Securities Act, that might be incurred by them in such capacities.

Item 16. Exhibits.

         See Exhibit Index.

Item 17. Undertakings.

        (a) 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 of 1933;

                (ii) To reflect in the prospectus any facts or events arising
after the effective date of this 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 Commission pursuant to Rule 424(b) under the Securities Act 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 in the effective registration statement;

                (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;

     PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in the registration statement.

                (2) That, for the purpose of determining any liability under
the Securities Act of 1933, 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.

                                      II-2




                (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.

        (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors and officers of the registrant pursuant to
the foregoing provision or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission 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 Act and
will be governed by the final adjudication of such issue.

                                      II-3



                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Basking Ridge, State of New Jersey, on the 26th day
of February, 2002.
