Important message on voting your AT&T proxy

To AT&T Manager-Stockholders:

As AT&T stockholders, you will receive your proxy materials in the coming days. The proxy statement includes several proposals to be voted on by stockholders; some of them submitted by our Board of Directors and others by stockholders.

I encourage you to exercise your right to vote and to consider the Board's recommendations when doing so. For each proposal, the Board has provided a thoughtful and comprehensive supporting statement for its recommendation. You can review the proposals and the Board recommendations in the "Matters to be Voted Upon" section of your proxy (pages 13-25).

If you have not received your proxy materials, you should receive them shortly. You can also access the annual report and the proxy statement by going to www.attproxy.com.

Thank you,

Randall
