                      Realization of the broadband vision

The  merger  of AT&T  Broadband  and  Comcast  Corp.  creates  a  communications
powerhouse and accelerates the potential of cable telephony.

By Paul La Plante

If you were to  develop  the first  television  program to be carried by the new
AT&T Comcast Corp.  -- a program that  chronicled  the events  leading up to the
merger of AT&T Broadband and Comcast Corp. announced in December -- what kind of
program would it be?

Judging from the outside-looking-in view seen through much of the media coverage
in the  second  half of 2001,  you might  guess it would be along the lines of a
"reality program" where speculation and intrigue abound.

But the behind-the-scenes  activities and single-minded focus of AT&T management
would be much more  accurately  depicted by a television  concept that  predates
even the invention of cable TV: the repeat.  That's because from start to finish
-- from AT&T's initial restructuring announcement in October 2000, to evaluation
of Comcast's overture last summer, to the culmination of the merger agreement in
December  --  management  returned  time and time again to one goal for the AT&T
Broadband business unit: maximize the creation of shareholder value.

AT&T and Comcast  shareholders  will have their say on the  proposed $72 billion
merger  later  this year when  votes are  taken,  and the  merger is  subject to
regulatory  review as well. But at this point,  the management teams of AT&T and
Comcast are confident the deal not only meets this goal of creating  shareholder
value,  but also is a win for  customers  because it's  positioned to bring more
services to more people more quickly.

Separately,  the  organizations are each forces to be reckoned with in their own
right:

o        AT&T  Broadband  is  the  United  States'  largest  broadband  services
         company,  providing television entertainment services to more than 13.5
         million customers across the nation as of the end of the third quarter.
         The company also provides  advanced  services,  such as digital  cable,
         high-speed cable Internet services and competitive local phone service.
o        Meanwhile,  Comcast is the  country's  third-largest  provider of cable
         services,  with about 8.5 million  customers as of the end of the third
         quarter,  and is  expanding  its cable  operations  to deliver  digital
         services and high-speed Internet service.

Together,  the strategic  combination  -- expected to be completed by the end of
the  year  --  will  create  one  of  the  premiere  communications,  media  and
entertainment companies in the world.

Bringing greater choice
For  starters,  it would  be the  United  States'  premiere  broadband  services
network,  serving about 22 million subscribers.  Further, the merger is intended
to put on the  fast-track a vision that  thousands  of AT&T people  already were
working toward -- bringing greater choice in affordable  broadband video,  voice
and data services to even more American homes.



AT&T Comcast Corp. will begin life with a clear mandate to  aggressively  expand
the availability of those services throughout its service areas, including plans
to bring a choice  in local  telephone  service  to more than 38  million  homes
passed by its cable systems.  The new company's  footprint includes 17 of the 20
largest  metropolitan  areas in the  country,  and its  scale  will  allow it to
accelerate the development and deployment of new broadband applications, such as
video on demand and interactive television.

So just how did the proposed AT&T Comcast Corp. come about?  And why was Comcast
chosen for the merger  with AT&T  Broadband  when it was no secret  others  were
vying for the  opportunity to link up with us? The answers rest,  again,  in the
focus on doing what created the most shareholder  value -- both today and in the
future. (See recap of key events on page 7.)

Closer look at the offer
Though   the   acceptance   of   Comcast's   offer   may   appear   to   have  a
"back-where-we-began-in-July"  feel to it given the company's initial bid, there
were significant differences that made the new offer the right one.

First, concerns about the voting structure of a combined company were addressed.
The proposal  accepted by AT&T calls for AT&T  shareholders  to own a 56 percent
economic  stake and about a 66 percent voting  interest in the new company.  And
the Roberts family, which owns Comcast Class B shares, will control one third of
the new company's outstanding voting interest.

Second,  the  economics  of the latest  offer mean that AT&T  shareholders  will
benefit from improved financials over the initial bid.

Third,  Comcast  management  fully  supports AT&T  Broadband's  cable  telephony
strategy.  After extensive  review of AT&T  Broadband's  industry-leading  cable
telephony expertise and infrastructure  during the evaluation  process,  Comcast
management  agreed  with AT&T that the merged  firm will be  well-positioned  to
accelerate and improve the delivery of telephony  services in Comcast's  service
areas, and that telephony has the potential to be a significant driver for value
creation for the merged firm.

Restructuring to proceed
AT&T intends to proceed with other aspects of its original  restructuring  plan,
including the creation of a tracking stock for AT&T Consumer,  which is expected
to be  distributed  to  AT&T  shareholders  this  summer  following  shareholder
approval.  And following the separation of AT&T Broadband and the  establishment
of the AT&T Consumer  tracking stock,  the familiar "T" stock symbol is intended
to reflect the financial  results of AT&T Business,  which will retain ownership
of the "AT&T" brand.

So with an  unanticipated  but welcome  change in how the  independence  of AT&T
Broadband will come about, the AT&T  restructuring plan of October 2000 remains:
create new businesses,  with each to become a publicly held business that trades
as a common stock or a tracking stock.

Terms of the  merger  will  accelerate  by a few months  the  departure  of AT&T
Chairman  and CEO Mike  Armstrong.  Armstrong  will serve as chairman of the new
AT&T Comcast Corp. when the merger closes,  instead of retiring from AT&T in May
2003 as he had planned.  Until the deal closes,  Armstrong will remain  Chairman
and CEO of AT&T.

"AT&T  Broadband and Comcast can accomplish  more together than we could alone,"
Armstrong says. "Our  shareholders  and our employees will both benefit from the
industry-leading growth we will achieve."



Sidebar:  A recap of key events
Oct. 25, 2000
AT&T announces plans to create new  businesses,  each operating under the "AT&T"
brand,  committed to uniform  standards of quality and continuing to bundle each
other's services through inter-company  agreements.  Under the plan, each of the
major units -- AT&T Business, AT&T Consumer, AT&T Broadband and AT&T Wireless --
was to become a publicly held business,  trading as a common stock or a tracking
stock.  The  plan's  goal  was to  provide  the  greatest  long-term  value  for
shareholders.

July 8, 2001
Comcast makes an unsolicited bid for the AT&T Broadband unit.

July 18, 2001
After  careful  review,  and based in part on the  advice  and  analysis  of its
financial  advisers,  the AT&T Board of  Directors  votes to reject the  Comcast
proposal,  feeling it does not  reflect  the full value of AT&T  Broadband.  The
Board also is concerned about the voting rights of AT&T  shareholders  under the
proposal. The Board instructs AT&T management to explore financial and strategic
alternatives  to find  one  that  provides  the  greatest  long-term  value  for
shareholders.

Dec. 9, 2001
Following submissions of bids from Comast and other interested parties, the AT&T
Board meets to consider the various  proposals.  The meeting  concludes with the
Board  instructing  management  to  continue  discussions  with  all  interested
parties,  saying it would  evaluate  the  potential  of all  proposals to create
long-term shareholder value.

Dec. 19, 2001
The AT&T Board gives unanimous approval and full support to
a merger of AT&T Broadband and Comcast, culminating a rigorous process to assess
strategic and financial  alternatives  for the Broadband  unit that would create
long-term shareholder value.

Terms of the agreement
Subject to the terms of the definitive agreement:

o AT&T will spin off AT&T  Broadband and  simultaneously  merge it with Comcast,
forming a new company to be called AT&T Comcast Corp.

o AT&T shareholders will receive approximately 0.34 shares of AT&T Comcast Corp.
for each share of AT&T they own  (subject to  adjustment  based on the number of
AT&T shares at closing).

o AT&T  shareowners  will own a 56 percent economic stake and about a 66 percent
voting interest in the new company. The Roberts family, which owns Comcast Class
B  shares,  will  control  one  third of the new  company's  outstanding  voting
interest.

o AT&T Comcast Corp.'s assets will consist of both companies'  cable TV systems,
as well as AT&T's  interests  in cable  television  joint  ventures and its 25.5
percent interest in Time Warner  Entertainment,  and Comcast's interests in QVC,
E! Entertainment, The Golf Channel and other entertainment businesses.



o The new company will assume  nearly $20 billion in debt and other  liabilities
from AT&T and its  subsidiaries,  as well as $5 billion of AT&T subsidiary trust
convertible  preferred  securities held by Microsoft Corp., making the aggregate
value of the transaction to AT&T  shareholders  worth $72 billion,  based on the
closing price of Comcast Class K stock on Dec. 19.

o The approximate .34 shares of AT&T Comcast that AT&T shareowners
would receive  represented a value  equivalent to $13.07 per AT&T share based on
Comcast's  closing  share price on Dec. 19, 2001.  AT&T  shareholders  also will
retain complete ownership of AT&T's traditional communications businesses.
