NEW YORK and PHILADELPHIA - 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.

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 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.
