AT&T Reaches At Home Litigation Settlement

Philadelphia, PA.

Comcast Payment of $170 Million Results in Update to First Quarter 2005 Results

Comcast Corporation (Nasdaq: CMCSA, CMCSK) today announced that AT&T Corp. reached a settlement of certain At Home litigation. Comcast will pay AT&T Corp. $170 million to reimburse it for Comcast's portion of AT&T's settlement. Pursuant to the terms of its acquisition of AT&T Broadband from AT&T, Comcast is contractually liable for 50% of the $340 million settlement amount for these lawsuits, which are described below. The settlement also releases all claims by AT&T and AT&T Broadband in the At Home bankruptcy. The settlement is subject to the approval of the United States Bankruptcy Court for the Northern District of California.

As Comcast noted in its April 28, 2005 press release, because this
settlement was reached prior to the filing of Comcast's Form 10-Q for the
first quarter 2005, it must reflect its portion of the settlement in its first
quarter earnings. Below are selected items from Comcast's release that
reflect the changes resulting from the payment obligation (amounts in millions
except per share data):

The lawsuits are: (i) a lawsuit filed against AT&T and others in Santa
Clara, California state court alleging various breaches of fiduciary duties,
misappropriation of trade secrets and other causes of action and (ii) an
action filed against AT&T in the District Court for the Northern District of
California alleging patent infringement. As part of the settlement, a lawsuit
filed in the United States Bankruptcy Court against AT&T, AT&T Broadband and
others seeking to recover alleged "preference" payments will be dismissed.
