by Comcast Corporation ("Comcast") and relates to shares of Series A common
stock, par value $0.01 per share (the "Series A Common Stock"), of At Home
Corporation, a Delaware corporation (the "Company" or the "Issuer"). Pursuant
to Rule 13d-3 under the Act, this Amendment No. 5 also relates to the shares of
Series A Common Stock issuable upon exercise of certain warrants owned by

     Item 4 of the Schedule 13D is hereby amended by inserting the following
immediately prior to the third to last paragraph thereof:

     On June 22, 2001, in a series of brokerage transactions, Comcast PC sold
900,000 shares of Series A Common Stock at an average price of $2.03 per share.

were outstanding 321,900,704 shares of Series A Common Stock and 85,595,578
shares of Series B Common Stock. Comcast currently beneficially owns 27,163,180
shares of Series A Common Stock, of which it has the right to acquire 2,138,580
shares based on the exercise of certain warrants by certain of its wholly-owned
subsidiaries set forth in Item 2. As of the date hereof and assuming the
conversion into Series A Common Stock of all warrants for Series A Common Stock
which Comcast has beneficial ownership of under Rule 13d-3, Comcast
beneficially owns an aggregate of 27,163,180 shares of Series A Common Stock,
or approximately 8.4%


                                  Page 5 of 7




of the shares of Series A Common Stock deemed outstanding (assuming such
exercise of the warrants, but without giving effect to any conversion of shares
of Series B Common Stock). Comcast Online and Comcast PC each currently
beneficially owns 25,024,600 shares of Series A Common Stock constituting
approximately 7.8% of the outstanding shares of Series A Common Stock, (without
giving effect to any conversion of shares of Series B Common Stock).

     Except as set forth in this Item 5(a), none of the Reporting Persons, nor
any other person controlling any Reporting Person beneficially owns any Shares.

     Part (b) of Item 5 of the Schedule 13D is hereby replaced in its entirety
as follows:

     After giving effect to the sales described in Item 4, Comcast has sole
power (i) to vote or direct the vote and (ii) to dispose of or direct the
disposition of the 27,163,180 shares of Series A Common Stock it beneficially
owns.

     After giving effect to the sales described in Item 4, Comcast Online has
sole power (i) to vote or direct the vote and (ii) to dispose of or direct the
disposition of the 25,024,600 shares of Series A Common Stock it beneficially

     Except as set forth herein, no transactions in the Series A Common Stock
have been effected during the past 60 days by the Reporting Persons or any
other person controlling any of the Reporting Persons, except that as described
