In the first kind of exchange, AT&T is offering to exchange the Broadband Eligible Notes for notes that, upon completion of the AT&T Comcast Transaction, will become New Broadband Notes. The New Broadband Notes will be obligations of AT&T Broadband Corp. and will be unconditionally guaranteed by AT&T Comcast Corporation and certain of its subsidiaries. Exchange ratios and interest rates for the New Broadband Notes will be announced by press release two business days prior to the expiration of the exchange offer. The exchange ratios and interest rates will be based upon spreads over the relevant reference U.S. Treasury rates as described in the Prospectus. If more than the proration percentage of any series of Broadband Eligible Notes is tendered and not withdrawn by the applicable expiration date, notes of that series will be accepted for exchange on a prorated basis.

In the second kind of exchange, AT&T is offering to exchange the AT&T Eligible Notes for New AT&T Notes that will remain solely obligations of AT&T and, upon completion of the AT&T Comcast Transaction, will have the revised terms described in the Prospectus, including the revised maturity date and/or interest rates set forth in the table above. The exchange offer for AT&T Eligible Notes is for all notes and is not subject to proration.

Neither AT&T, AT&T Broadband, nor any other entity will receive any proceeds from the issuance of the new notes in the exchange offer. The issuance of the New Broadband Notes is essentially a new offering of notes that will be obligations of AT&T Broadband and will reduce the amount that AT&T Broadband would otherwise be required to pay to AT&T upon completion of the AT&T Comcast Transaction. The issuance of the New AT&T Notes is essentially a refinancing with respect to certain of those notes that will remain obligations of AT&T after the completion of the AT&T Comcast Transaction.

To participate in either kind of exchange, bondholders must consent to an amendment to the terms of their original notes to the extent their notes are accepted for exchange. This amendment will provide, among other things, that in the AT&T Comcast Transaction, neither AT&T Comcast Corporation nor any of its affiliates needs to assume AT&T's obligations on the original notes. The amendment will amend any series of notes so long as more than 50 percent by principal amount of that series consents. The terms of and the liquidity of the trading market for the original notes may be affected, even for non-participating holders, by the exchange offer.

AT&T will not accept any notes of a particular series unless more than 50 percent of the principal amount of that series of notes has been validly tendered and not withdrawn by the applicable expiration date. The closing of the exchange offer is subject to the conditions that are described in the Prospectus.

The exchange offer and withdrawal rights will expire at 12:00 midnight, New York City time, on November 1, 2002 unless extended. AT&T will announce any extensions by press release or other permitted means no later than 9:00 a.m., New York City time, the day after expiration of the exchange offer for that series of notes. Holders may withdraw any notes tendered until the expiration of the exchange offer for that series of notes.

The terms of the exchange offer and other information relating to AT&T and Comcast are set forth and incorporated by reference in the Prospectus and should be read carefully, including the risk factors contained and incorporated by reference in the Prospectus.
