Proxy Voting Reminder

Dear Shareholder,

Our records indicate that you may not have voted your AT&T proxy. We encourage you to vote your shares by telephone or Internet, or sign and mail the enclosed duplicate proxy card in the envelope provided.

The Board of Directors recommends a vote FOR proposals 1, 1a, 2 and 3 and AGAINST proposals 4, 5, 6, 7, 8 and 9. Please note that approval of the merger agreement among SBC, AT&T and Merger Sub (Proposal 1 on proxy card) requires the affirmative vote of the holders of at least a majority of the outstanding shares of AT&T common stock entitled to vote. The failure to submit a proxy card (or to submit a proxy by telephone or by Internet vote or to vote in person at the annual meeting) or the abstention from voting by a shareholder will have the same effect as a vote against adoption of the merger agreement. Election of directors (Proposal 2) requires a plurality of the votes cast. All of the other voting items require a majority vote of the shares that are voted.

Remember: it is important to vote your shares by telephone, Internet, proxy card, or in person at the annual meeting. We appreciate your participation in the voting process for our 2005 Annual Meeting.

(-s- Robert S. Feit)

Robert S. Feit
Vice President — Law and Secretary
