                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of December 12, 2001 (herein called
the "Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and Bank One Trust Company, N.A., as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof, limited at the date
hereof in aggregate principal amount to $750,000,000; provided that the Company
may from time to time, without notice to or the consent of the Holders of
Securities, create and issue further Securities of this Series (the "Additional
Securities") having the same terms and ranking equally and ratably with the
Securities in all respects, or in all respects except for the payment of
interest accruing prior to the Issue Date or except for the first payment of
interest following the Issue Date of such Additional Securities. Any Additional
Securities will be consolidated and form a single series with the Securities and
shall have the same terms as to status, redemption or otherwise as the
Securities. Any Additional Securities may be issued pursuant to authorization
provided by a resolution of the Board of Directors of Cingular Wireless
Corporation, the manager of the Company, a supplement to the Indenture, or under
an Officers' Certificate pursuant to the Indenture.

                  The Securities of this series are subject to redemption upon
not less than 30 days' but not more than 60 days' notice by mail, at any time,
as a whole or in part, at the election of the Company, at a redemption price
equal to (i) 100% of the principal amount of the Securities to be redeemed,
together with accrued interest to the Redemption Date, if any, but interest
installments whose Stated Maturity is on or prior to such Redemption Date shall
be payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture, plus (ii) the
Make-Whole Amount, if any.

                  The Redemption Price will be calculated assuming a 360-day
year consisting of twelve 30-day months.

                  "Make-Whole Amount" means the excess, if any, of the aggregate
present value as of the Redemption Date of each dollar of principal being
redeemed and the amount of interest (exclusive of interest accrued to the
Redemption Date) that would have been payable in respect of such dollar if such
prepayment had not been made, determined by discounting, on a semiannual basis,
such principal and interest at the Treasury Rate, plus 0.25% from the date on
which such principal and interest would have been payable if the Security had
not been redeemed, over the principal amount of the Security being redeemed.

computation of U.S. Treasury securities with a constant maturity, as compiled by
and published in the most recent Statistical Release that has become publicly
available at least two Business Days prior to the Redemption Date, equal to the
then remaining maturity of this Security; if no maturity exactly corresponds to
such maturity, yields for the two published maturities most closely
corresponding to such maturity shall be calculated pursuant to the immediately
preceding clause and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight-line basis, rounding in each of such relevant
periods to the nearest month; or (ii) if the Statistical Release is not
published during the week preceding the calculation date or does not contain
such yields, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such Redemption Date. The Treasury
Rate shall be calculated on the third Business Day preceding the Redemption
Date.

                  "Comparable Treasury Issue" means the U.S. Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term ("Remaining Life") of this Security that would be utilized,
at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of this Security.

                  "Comparable Treasury Price" means (i) the average of three out
of five Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii)
if the Independent Investment Banker obtains fewer than five such Reference
Treasury Dealer Quotations, the average of all such quotations.

                  "Independent Investment Banker" means (i) any of Lehman
Brothers Inc., Goldman, Sachs & Co. or J.P. Morgan Securities Inc. and their
respective successors, as selected by the Company, or (ii) if all those firms

Goldman, Sachs & Co. and J.P. Morgan Securities Inc. and their respective

new Security or Securities of this series and of like tenor for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the
cancellation hereof.

                  The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security or certain restrictive covenants and
Events of Default with respect to this Security, in each case upon compliance
with certain conditions set forth in the Indenture.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the Securities at the time Outstanding of each series to be affected. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive
compliance by the Company 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 Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security 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
Security.

                  As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with

                                      -7-

<PAGE>

such request, and the Trustee shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

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

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company in any place where the principal
of and any premium and interest on this Security are payable, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, shall be issued to the designated transferee or
transferees.

                  The Securities of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof. As provided in the Indenture and subject to certain limitations therein
set forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same.

                  No service charge shall be made to a Holder for any such
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

                  Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and none of
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

conflicts of laws.

the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof, limited at the date
hereof in aggregate principal amount to $750,000,000; provided that the Company
may from time to time, without notice to or the consent of the Holders of
Securities, create and issue further Securities of this Series (the "Additional
Securities") having the same terms and ranking equally and ratably with the
Securities in all respects, or in all respects except for the payment of
interest accruing prior to the Issue Date or except for the first payment of
interest following the Issue Date of such Additional Securities. Any Additional
Securities will be consolidated and form a single series with the Securities and
shall have the same terms as to status, redemption or otherwise as the
Securities. Any Additional Securities may be issued pursuant to authorization
provided by a resolution of the Board of Directors of Cingular Wireless
Corporation, the manager of the Company, a supplement to the Indenture, or under
an Officers' Certificate pursuant to the Indenture.

                  The Securities of this series are subject to redemption upon
not less than 30 days' but not more than 60 days' notice by mail, at any time,
as a whole or in part, at the election of the Company, at a redemption price
equal to (i) 100% of the principal amount of the Securities to be redeemed,
together with accrued interest to the Redemption Date, if any, but interest
installments whose Stated Maturity is on or prior to such Redemption Date shall
be payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture, plus (ii) the
Make-Whole Amount, if any.

                  The Redemption Price will be calculated assuming a 360-day
year consisting of twelve 30-day months.

                  "Make-Whole Amount" means the excess, if any, of the aggregate
present value as of the Redemption Date of each dollar of principal being
redeemed and the amount of interest (exclusive of interest accrued to the
Redemption Date) that would have been payable in respect of such dollar if such
prepayment had not been made, determined by discounting, on a semiannual basis,
such principal and interest at the Treasury Rate, plus 0.30% from the date on
which such principal and interest would have been payable if the Security had
not been redeemed, over the principal amount of the Security being redeemed.

transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
