     The following information amends the Schedule 13D dated May 12, 1980, as
previously amended (as so amended, the "Schedule 13D").

     Unless otherwise indicated, each capitalized term used but not defined
herein shall have the meaning assigned to such term in the Schedule 13D.

Item 2. Identity and Background

     On September 11, 2001, Sural Corporation merged with and into Sural LLC, a
newly formed Delaware limited liability company ("Sural"). Sural was the
surviving entity in the merger. Its managing member is Brian L. Roberts, who
holds approximately 72% of its outstanding units of membership interests.
Sural's principal place of business and executive offices are at 1105 North
Market Street, Suite 1219, Wilmington, Delaware 19801.

Item 4. Purpose of Transaction

     (a) On December 19, 2001, Comcast entered into an Agreement and Plan of
Merger (the "Merger Agreement") with AT&T Corp., a New York corporation
("AT&T"), AT&T Broadband Corp., a Delaware corporation and a wholly owned
subsidiary of AT&T ("AT&T Broadband"), AT&T Comcast Corporation, a Pennsylvania
corporation ("Parent"), AT&T Broadband Acquisition Corp., a Delaware
corporation and a wholly owned subsidiary of Parent, and Comcast Acquisition
Corp., a Pennsylvania corporation and a wholly owned subsidiary of Parent,
which provides, among other things, that each of Comcast and AT&T Broadband
will merge with and become a wholly-owned subsidiary of Parent (the "Mergers").

     In connection with the Merger Agreement, on December 19, 2001, Sural and
Brian L. Roberts entered into a Support Agreement (the "Support Agreement")
with AT&T, Comcast and Parent. The Support Agreement provides, among other
things, that Sural will vote its shares of Comcast voting stock: (i) in favor
of adoption of the Merger Agreement and approval of the transactions
contemplated by the Merger Agreement, (ii) against any action or agreement that
would reasonably be expected to result in a breach of any covenant,
representation or warranty or any other obligation or agreement of Comcast
under the Merger Agreement or that would reasonably be expected to result in
any of the conditions to the obligations of the parties under the Merger
Agreement not being fulfilled, (iii) in favor of any other matter relating to
the consummation of the transactions contemplated by the Merger Agreement with
respect to which Sural may be entitled to vote and (iv) against any other
matter that would reasonably be expected to prevent, interfere with or delay
consummation of the transactions contemplated by the Merger Agreement,
including any transaction that would result in a breach of the Merger Agreement
by Comcast.

     In addition, Sural has agreed in the Support Agreement not to transfer
ownership of any of the shares of Parent Class B Common Stock it will receive
in the Mergers prior to the tenth anniversary of the completion of the Mergers,
except to certain permitted transferees or in a transaction that is approved by
disinterested directors and shareholders, and Brian L. Roberts has





                                                              Page 5 of 7 pages


agreed not to transfer ownership of any of his securities or other equity
interests in Sural prior to the tenth anniversary of the completion of the
Mergers, except to certain permitted transferees or in a transaction that is
approved by disinterested directors and shareholders. Under the terms of the
Support Agreement, each permitted transferee of any of such securities will be
required to agree, as a condition to such transfer, to the same transfer
restrictions.

     Sural has further agreed in the Support Agreement that, after the
completion of the Mergers and until April 2005, Sural will vote its shares of
Parent Class B Common Stock against any proposed amendment to Article SIXTH of
the Articles of Incorporation of Parent (the Article setting forth, among other
things, the composition of the Parent Board of Directors and other Parent
governance arrangements, in each case after completion of the Mergers). Sural
has further agreed in the Support Agreement that if Brian L. Roberts dies or
becomes incapable of performing his duties prior to the fifth anniversary of
the completion of the Mergers, then, unless Ralph J. Roberts has sole voting
power in respect of the election of directors with respect to all outstanding
shares of Parent Class B Common Stock, from the date of his death or inability
to perform his duties until the fifth anniversary of the completion of the
Mergers, Sural will vote its shares of Parent Class B Common Stock in any
election of Parent directors in the same proportion as the holders of shares of
Parent Common Stock (other than Parent Class B Common Stock and any other
voting shares of Parent owned by Brian L. Roberts or Sural) vote in such
election of directors. Under the terms of the Support Agreement, each permitted
transferee of any of such securities will also be required to agree, as a
condition to such transfer, to the same voting obligations.

     Copies of the Merger Agreement and the Support Agreement are filed as
Exhibits 1 and 2, respectively, hereto and are incorporated herein by
reference. The description herein of certain provisions of the Merger Agreement
and the Support Agreement are qualified in their entirety by reference thereto.

     (b) Except as described in subparagraph (a) above, neither Brian L.
Roberts, Sural nor any executive officer or director of Sural has any present
plans or proposals that relate to or would result in:

          (i) the acquisition by any person of additional securities of
     Comcast, or the disposition of securities of Comcast;

          (ii) an extraordinary corporate transaction, such as a merger,
     reorganization or liquidation, involving Comcast or any of its
     subsidiaries;

          (iii) a sale or transfer of a material amount of assets of Comcast or
     any of its subsidiaries;

          (iv) any change in the present board of directors or management of
     Comcast, including any plans or proposals to change the number or term of
     directors or to fill any existing vacancies on the board;





                                                              Page 6 of 7 pages


          (v) any material change in the present capitalization or dividend
     policy of Comcast;

          (vi) any other material change in Comcast's business or corporate
     structure;

          (vii) changes in Comcast's charter, bylaws or instruments
     corresponding thereto or other actions which may impede the acquisition of
     control of Comcast by any person;

          (viii) causing a class of securities of Comcast to be delisted from a
     national securities exchange or to cease to be authorized to be quoted in
     an inter-dealer quotation system of a registered national securities
     association;

          (ix) a class of equity securities of Comcast becoming eligible for
     termination of registration pursuant to Section 12(g)(4) of the Exchange
     Act; or

          (x) any action similar to those enumerated in (i) - (ix) above.

     Notwithstanding the foregoing, the parties filing this statement reserve
the right to attempt to effectuate any such transaction or transactions in the
future, subject to any applicable restrictions under contract or applicable
law.
