To: Employee Shareholders

Dear Colleague:

The AT&T Annual Report on Form 10K/A and Proxy Statement/Prospectus, and other investor-related materials, are available online for viewing and downloading by employee shareholders on the AT&T Investor Relations Website at http://www.att.com/ir/.

By having employee shareholders access these materials electronically, instead of requesting paper copies, employees will help AT&T reduce its mailing and printing costs.

Employee shareholders will receive the following proxy materials in the mail: a proxy card, an electronic access confirmation notice that also includes travel directions to the annual meeting, a proxy voting insert and a business reply envelope. Employees are encouraged to vote their shares electronically by using either the telephone (1-800-273-1174) or the Internet (http://att.proxyvoting.com/). With these two electronic voting options, employees will be able to vote their shares in the same manner as if they had signed, dated and returned the proxy card by mail. If you elect to vote your shares electronically, please do not return your proxy card. Employee shareholders who would like to obtain paper copies of the Annual Report on Form 10K/A and/or Proxy Statement/Prospectus, should contact our transfer agent, EquiServe (1-800-348-8288), no later than 15 days before the June 30, 2005, annual meeting date.
