Item 3 of the Schedule 13D is hereby amended by adding the following to the end thereof: On June 11, 2001, AT&T and Comcast PC entered into an agreement (the "Amended and Restated Comcast Share Issuance Agreement"), which amended and restated the Comcast Share Issuance Agreement, and thereafter completed the transactions contemplated by the Amended and Restated Comcast Share Issuance Agreement. Pursuant to the Amended and Restated Comcast Share Issuance Agreement, AT&T issued 80,300,930 shares of AT&T common stock to Comcast PC. As a result of this transaction, the Put granted to Comcast under the Letter Agreement, which was exercised on January 11, 2001, was fully satisfied. AT&T did not acquire any Series A Common Stock in this transaction. AT&T granted Comcast PC limited registration rights with respect to the AT&T common stock issued to Comcast PC. The foregoing description of the Amended and Restated Comcast Share Issuance Agreement is qualified in its entirety by reference to the text of the Amended and Restated Comcast Share Issuance Agreement, which is filed as Exhibit 1 to this Amendment No. 6 and is incorporated herein by reference. ITEM 4. PURPOSE OF TRANSACTION. Item 4 of the Schedule 13D is hereby amended by adding the following at the end thereof: On June 8, 2001, Excite@Home announced that AT&T and Excite@Home had agreed to negotiate an arrangement relating to Excite@Home's network and engineering operations that differs from that contemplated by the LOA. If AT&T and Excite@Home reach agreement on the revised arrangements, (1) AT&T would provide consulting and support services on commercially reasonable, arm's-length terms; and (2) AT&T would assist Excite@Home in implementing an updated network plan to augment performance Page 2 of 5 levels in Excite@Home's network, instead of the outsourcing arrangement contemplated in the LOA.
