FOR IMMEDIATE RELEASE:

                          TIME WARNER CABLE AND COMCAST
                  TO ACQUIRE ASSETS OF ADELPHIA COMMUNICATIONS

                COMPANIES ALSO TO SWAP CERTAIN CABLE SYSTEMS AND
               UNWIND COMCAST'S INTERESTS IN TIME WARNER CABLE AND
                        TIME WARNER ENTERTAINMENT COMPANY

           TRANSACTIONS TO EXPAND BOTH COMPANIES' CABLE FOOTPRINTS AND
                  ENHANCE THEIR GEOGRAPHIC SUBSCRIBER CLUSTERS,
   SPEEDING THE DELIVERY OF NEW PRODUCTS IN AREAS CURRENTLY SERVED BY ADELPHIA

NEW YORK AND PHILADELPHIA, APRIL 21, 2005 - Time Warner Inc. (NYSE:TWX) and
Comcast Corporation (Nasdaq:CMCSA, CMCSK) today announced that they have reached
definitive agreements to acquire substantially all the assets of Adelphia
Communications Corporation (OTC: ADELQ) for a total of $12.7 billion in cash and
16% of the common stock of Time Warner's cable subsidiary, Time Warner Cable
Inc. Time Warner Cable and Comcast also will swap certain cable systems. In
addition, Time Warner Cable will redeem Comcast's interests of 17.9% in Time
Warner Cable and 4.7% in Time Warner Entertainment Company, L.P. (TWE) (together
an effective 21% economic ownership of Time Warner Cable) in an efficient and
mutually beneficial way.

These transactions will serve to expand both companies' cable footprints and
improve the geographic clusters of their subscribers. Importantly, consumers in
areas now served by Adelphia will benefit significantly from the accelerated
deployment of video, high-speed data, voice and other advanced services.

As a result of these transactions, Time Warner Cable will gain systems passing
approximately 7.5 million homes, with approximately 3.5 million basic
subscribers. Time Warner Cable will then manage a total of approximately 14.4
million well-clustered basic subscribers. Time Warner will own 84% of Time
Warner Cable's common stock, and the cable company will become a publicly traded
company at the time of closing.

Comcast will emerge from these transactions with approximately 1.8 million
additional basic subscribers for a net cash investment of approximately $1.5
billion. Following these transactions, Comcast will serve a total of
approximately 23.3 million customers. Comcast's clusters in Washington, D.C.,
Florida, Massachusetts and Pennsylvania will be enhanced, and Comcast will
divest its interests in Time Warner Cable and TWE in transactions designed to be
tax-free to all parties. Comcast's attributable subscribers, as calculated under
the Federal Communications Commission (FCC) rules, will remain under 30% of the
multi-channel video subscribers in the United States.

Time Warner Chairman and Chief Executive Officer Dick Parsons said: "I'm very
pleased that we're able to take full advantage of this unique opportunity to
grow our company at a



fair price and move it forward - strategically, operationally and financially.
Consistent with our strategy, these transactions will better position us to
compete, improve returns and create shareholder value. At Time Warner Cable,
we'll gain important scale, enhance our subscriber clusters and accelerate
growth. As we plan the smooth integration of these new cable systems, we'll stay
focused on meeting all of Time Warner's financial and operational objectives,
while evaluating how to best employ our significant remaining capacity to
improve shareholder returns. My thanks to Brian Roberts and his Comcast team for
being such fine partners in this process that produced beneficial results for
both companies."

Brian L. Roberts, Chairman and Chief Executive Officer of Comcast, said: "These
transactions underscore our belief that there has never been a better time to be
in the cable business. Adding these subscribers, many of whom are in
high-growth, geographically desirable areas, will allow us to roll out our new
products and services rapidly. Our vision remains to provide customers with more
choice and control of their entertainment and communication services, and to
generate superior shareholder returns. I would like to thank Dick Parsons and
everyone at Time Warner for helping to achieve such a positive outcome for all
parties."

TERMS OF PROPOSED TRANSACTIONS

In the proposed transactions:

- -     Time Warner Cable and Comcast will each acquire a portion of Adelphia's
      assets, representing approximately 5.0 million basic cable subscribers in
      the aggregate. Time Warner Cable will pay $9.2 billion in cash and will
      issue common shares representing 16% of Time Warner Cable's outstanding
      common equity (taking into account the redemption transaction with
      Comcast) to Adelphia stakeholders in connection with its acquisition
      agreement. Comcast will pay $3.5 billion in cash.

- -     Time Warner Cable and Comcast have agreed to swap certain cable systems to
      enhance their respective geographic clusters of subscribers.

- -     Time Warner Cable will redeem Comcast's 17.9% interest in Time Warner
      Cable, now held in an FCC-mandated trust, in exchange for a subsidiary
      holding Time Warner Cable systems serving nearly 600,000 subscribers, as
      well as approximately $1.856 billion in cash.

- -     TWE will redeem Comcast's 4.7% interest in TWE, now held in an
      FCC-mandated trust, in exchange for cable systems serving more than
      150,000 subscribers, as well as approximately $133 million in cash.

- -     Comcast's net cash investment in these transactions will be $1.5 billion.

- -     The purchase of the Adelphia assets is not dependent on the occurrence of
      the system swaps and redemption transactions between Time Warner and
      Comcast.

                                                                               2


Steve Burke, Chief Operating Officer of Comcast, said, "The Adelphia
transaction, the various system swaps, and the redemption of our Time Warner
Cable interests will allow us to enhance our key clusters. It is truly a perfect
fit. We look forward to quickly integrating the 1.8 million additional
subscribers just as we did when we acquired AT&T Broadband and its 13 million
subscribers in 2002. Most importantly, we look forward to providing all our
subscribers, both old and new, with a complete suite of integrated
communications and entertainment products."

Don Logan, Chairman of Time Warner's Media & Communications Group, said: "We
like the cable business. It's the only platform today that can deliver enhanced
digital video, high-speed data and voice services to consumers, and we have
great confidence in its future. Our newly acquired systems will give us a bigger
and better-clustered cable footprint, built around five large clusters,
including New York City and Los Angeles. Together with Glenn Britt and the Time
Warner Cable team, we'll bring our experience in innovation and proven operating
track record to improving and growing the performance of these new systems."

OUTCOME FOR TIME WARNER

When these transactions close, Time Warner will own 84% of Time Warner Cable's
common stock, which will continue to consist of Class A shares and Class B
super-voting shares. The remaining 16% of Time Warner Cable's common equity
initially will be owned by Adelphia stakeholders and is expected to be publicly
traded in the form of Class A shares. In addition to its 84% stake in the
publicly traded Time Warner Cable, Time Warner also will own a direct non-voting
common equity interest of approximately $2.9 billion in a subsidiary of Time
Warner Cable. The acquisition will be accounted for as an asset purchase. Time
Warner said that it expects to retain significant financial flexibility, while
maintaining its strong investment-grade debt rating.

Taking into account the proposed acquisition, swaps and redemptions, on a net
basis, Time Warner Cable will gain approximately 3.5 million basic video
subscribers. Specifically, Time Warner Cable will add around 3 million Adelphia
subscribers and more than 1 million Comcast subscribers, and will give Comcast
approximately 750,000 current Time Warner Cable subscribers. It will then manage
a total of approximately 14.4 million basic subscribers - 12.9 million
consolidated and 1.5 million in 50%-owned continuing joint ventures with
Comcast. That will make Time Warner Cable the second-largest multi-channel video
provider in the U.S. - ahead of all other cable operators, except for Comcast,
and ahead of both major satellite companies.

Once these transactions are complete, 85% of Time Warner Cable's managed
subscribers will be located in five large clusters, including (in round
numbers): 3.1 million in New York, 2.6 million in Texas, 2.4 million in
California, 2.3 million in Ohio and 1.9 million in the Carolinas. Time Warner
Cable will be the largest cable provider in both New York City and Los Angeles,
cities which anchor the country's two largest designated market areas (DMAs).

As part of his current duties as Chairman of Time Warner's Media &
Communications Group, Mr. Logan will become non-executive Chairman of Time
Warner Cable's board of

                                                                               3


directors. Glenn Britt, who now serves as Time Warner Cable's Chairman and Chief
Executive Officer, will remain Chief Executive Officer and also will be named
President.

Mr. Britt said: "We're very excited about this opportunity and look forward to
taking over the day-to-day management of these new systems. Over the last few
months, we've done extensive due diligence on the Adelphia properties and have a
very realistic view of how we can create new value. We expect a smooth
integration, and we'll quickly bring greater choice to consumers with our
popular enhanced digital video and high-speed data services. We also are well
positioned to compete effectively for telephone customers with our new Digital
Phone service. We have the technological, managerial and operational expertise
that will allow us to drive penetration rates and improve performance."

OUTCOME FOR COMCAST

Taking into account the proposed acquisition, swaps and redemptions, on a net
basis, Comcast will gain approximately 1.8 million basic video subscribers.
Specifically, Comcast will add approximately 2.1 million Adelphia subscribers
through the acquisition and the swap, and approximately 750,000 Time Warner
cable subscribers through the redemptions of Comcast's interest in Time Warner
Cable and TWE and the swap. Comcast will give Time Warner more than 1 million
subscribers. Comcast will serve approximately 23.3 million owned and operated
subscribers and be attributed with approximately 3.5 million additional
subscribers held in various partnerships. Comcast will remain the largest
multi-channel video provider in the U.S. and the nation's largest high-speed
Internet provider. As a result of these transactions, Comcast will expand its
presence in such key geographic areas as Washington D.C., West Palm Beach,
Boston and Pittsburgh.
