The Issuer's principal executive offices are located at 425 Broadway Street, Redwood City, CA 94063. Pursuant to Rule 13d-3 under the Exchange Act, this Amendment No. 5 also relates to the shares of Series A Common Stock issuable upon conversion of shares of the Series B common stock, par value $0.01 per share ("Series B Common Stock"), of Excite@Home.

Item 3 of the Schedule 13D is hereby amended by adding the following to the end thereof: On May 18, 2001, AT&T, Cox and Cox@Home, Inc., a wholly owned subsidiary of Cox ("Cox@Home"), entered into a share issuance agreement (the "Cox Share Issuance Agreement") and completed the transactions contemplated by the Cox Share Issuance Agreement. Pursuant to the Cox Share Issuance Agreement, AT&T issued 75 million shares of AT&T common stock to Cox@Home. As a result of this transaction, the Put granted to Cox under the Letter Agreement, which was exercised on January 11, 2001, has been satisfied in full. AT&T will not acquire any Series A Common Stock in this transaction. AT&T granted Cox@Home limited registration rights with respect to the AT&T common stock issued to Cox@Home. Also on May 18, 2001, AT&T and Comcast PC Investments Inc., a wholly owned subsidiary of Comcast ("Comcast PC"), entered into a share issuance agreement (the "Comcast Share Issuance Agreement"), pursuant to which AT&T agreed to issue shares of AT&T common stock to Comcast PC. The exact number of shares of AT&T common stock to be issued to Comcast PC will depend on recent trading prices of AT&T common stock and of Series A Common Stock at the time of closing, but it is expected to be in excess of 80 million shares of AT&T common stock. It is expected that the transactions contemplated by the Comcast Share Issuance Agreement will be completed in June 2001, at which time the Put granted to Comcast under the Letter Agreement, which was exercised on January 11, 2001, will be fully satisfied. AT&T will not acquire any Series A Common Stock in this transaction. AT&T will grant Comcast PC limited registration rights with respect to the AT&T common stock to be issued to Comcast PC at the closing.
