AT&T Inc., a corporation duly organized and existing under the laws of the State of Delaware (herein called “AT&T”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of Five Hundred Million Dollars ($500,000,000) on November 15, 2013 (the “Maturity Date”), and to pay interest on said principal sum from November 17, 2008 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on May 15 and November 15 in each year, commencing on May 15, 2009 (each an “Interest Payment Date”) and on the Maturity Date, at the interest rate of 6.70% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as

provided in such Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on May 1 or November 1, as the case may be (each, a “Regular Record Date”), next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 15 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Any money that AT&T deposits with the Trustee or any Paying Agent for the payment of principal or any interest on this Note that remains unclaimed for two years after the date upon which the principal and interest are due and payable, will be repaid to AT&T upon AT&T’s request unless otherwise required by mandatory provisions of any applicable unclaimed property law. After that time, unless otherwise required by mandatory provisions of any unclaimed property law, the Holder of this Note will be able to seek any payment to which such Holder may be entitled to collect only from AT&T.

If the Notes are issued in definitive form, payment of the principal and interest on this Note due at the Maturity Date or upon redemption will be made at the Maturity Date or upon redemption, as the case may be, upon presentation of this Note, in immediately available funds, at the office of The Bank of New York Mellon, the Paying and Transfer Agent and Registrar for the Notes, currently located at 101 Barclay Street, New York, New York 10286.

Payment of interest on this Note due on an Interest Payment Date, other than interest at maturity or upon redemption, may be paid by check mailed to the address of the Holder entitled thereto as such address shall appear in the Note register. Notwithstanding the foregoing, (1) the Depository as Holder of the Notes or (2) a Holder of more than U.S.$5,000,000 in aggregate principal amount of Notes in definitive form is entitled to require the Paying Agent to make payments of interest, other than interest due at maturity or upon redemption, by wire transfer of immediately available funds into an account maintained by the Holder in the United States, by sending appropriate wire transfer instructions as long as the Paying Agent receives the instructions not less than ten days prior to the applicable Interest Payment Date.

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time outstanding to waive compliance by AT&T with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of AT&T, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.
