                         INTELLECTUAL PROPERTY AGREEMENT

         This Intellectual Property Agreement ("Agreement") is dated this 17th

("BellSouth").

                                    RECITALS:

         WHEREAS, in connection with the Amended and Restated Contribution and
Formation Agreement dated as of April 4, 2000 (the "Contribution Agreement")
among BellSouth Corporation, SBC Communications, Inc. and Cingular (formerly,
Alloy, LLC), BellSouth and Cingular entered into an Intellectual Property
License Agreement ("License") and a Transition Marks Agreement (the "TM
Agreement"), each dated October 2, 2000;

         WHEREAS, BellSouth has requested an extension for filing patent
applications pursuant to the License until December 31, 2001 for those
applications based on technology invented by BellSouth Leaseco employees and in
BellSouth's or its representative's possession in the form of an invention
disclosure or a draft patent application on or before April 2, 2001; and

         WHEREAS, BellSouth has agreed to provide Cingular with additional
rights as Licensee under the License; and

         WHEREAS, Cingular has requested an extension of the use of the
BellSouth Marks under the TM Agreement until December 31, 2001;

         NOW, THEREFORE, in consideration of the foregoing premises, BellSouth
and Cingular agree as follows:

1.       FILING OF PATENTS. For those patent applications set forth in Schedule
         1 which were received by BellSouth's law firms as of April 2, 2001 (the
         "Law Firm Patents"), BellSouth shall have until December 31, 2001 to
         file the applications as regular patent applications, foreign patent
         applications or provisional applications. For those invention
         disclosures from BellSouth Leaseco employees set forth in Schedule 2
         for inventions developed on or before April 2, 2001 (the "Employee
         Patents", the Law Firm Patents and the Employee Patents are
         collectively referred to herein as the "Patents"), BellSouth shall have
         until December 31, 2001 to file patent applications as regular patent
         applications, foreign patent applications or provisional applications.

2.       OWNERSHIP OF PATENTS. To the extent the Patents are filed on or before
         December 31, 2001, BellSouth shall own full right, title and interest
         to any patents and patent applications resulting therefrom, including
         any and all continuations, divisionals, continuation-in-parts, and
         international patents and patent

<PAGE>

         applications relating thereto. Cingular will have a license to the
         Patents in accordance with the License. To the extent the Patents are
         not filed on or before December 31, 2001, Cingular shall own full
         right, title and interest to any patents and patent applications
         resulting therefrom, including any and all continuations, divisional,
         continuation-in-parts, and international patents relating thereto and
         shall reimburse BellSouth its attorney's fees incurred in preparing and
         prosecuting such Patents to issuance and in assigning them to Cingular.

3.       INNOVATION AWARDS. Cingular will pay all Innovation Awards (defined
         below) relating to the Law Firm Patents. BellSouth will pay all
         innovation awards relating to the Employee Patents. For purposes of
         this Agreement, "Innovation Awards" are awards of $1000 per inventor
         per application filing and $2000 per inventor per application issuance
         payable to employees employed by the BellSouth Leaseco on the on the
         day that the Patent application is filed or the date that the Patent
         issues, as applicable. If BellSouth is able to obtain revenues from the
         Law Firm Patents, from its profits (revenues less any BellSouth
         expenses incurred to obtain the revenues from the patents) BellSouth
         will reimburse Cingular for the Innovation Awards it has actually paid
         to its employees.

4.       REPRESENTATIONS AND WARRANTIES. BellSouth represents that, to the best
         of its knowledge, Schedules 1 and 2 contain all invention disclosures
         and patent applications that are the subject of this agreement.
         However, Schedule 1 may be amended to include additional invention
         disclosures and patent applications that meet the above criteria but
         were not known to BellSouth at the time of this Agreement.

5.       COOPERATION. Cingular will cooperate and encourage the BellSouth
         Leaseco employees to cooperate with BellSouth and Cingular further
         agrees to execute all documents deemed reasonably necessary by
         BellSouth and Cingular to record and perfect BellSouth's rights to the
         patents and patent applications contemplated by this Agreement.

6.       LICENSEE RIGHTS. At BellSouth's sole discretion, Cingular, as Licensee
         (herein "Licensee") shall have the right to assert a claim against, or
         counter-sue, any infringer of any of the Patents in the event that such
         infringer asserts a patent infringement claim against Licensee or sues
         Licensee for patent infringement. Licensee shall pay all costs and
         expenses associated with such lawsuit. BellSouth agrees to join in such
         suit at Licensee's expense and to execute any necessary papers for such
         suit. BellSouth may, at its discretion, participate in, and control any
         such claim or suit, at Licensee's expense, to the extent that the claim
         or suit may involve the validity, ownership, scope or interpretation of
         a Patent. BellSouth may, at its sole discretion, at the request of
         Cingular, license one or more Patents in settlement of any such suit or
         in response to a threat thereof. Any sum recovered in such suit or in
         settlement thereof shall be retained by BellSouth for its own use and
         benefit, and Licensee shall have no rights whatsoever in any such
         recovery or settlement. Neither Licensee nor any affiliate of Licensee
         shall

<PAGE>

         foster or encourage any infringement of the Patents by any third-party.
         If Licensee or any of its affiliates shall engage in such conduct,
         BellSouth shall have the right to deem such conduct a material breach
         of this Agreement, which breach shall be a basis of termination of this
         Agreement. All other terms and conditions of the License shall remain
         in full force and effect according to their terms. Licensee also agrees
         to indemnify and hold BellSouth harmless from and against all claims,
         judgments, costs, expenses, attorneys fees and liabilities of any
         nature whatsoever arising out of or in connection with any claim or
         suit involving the assertion by Cingular or by BellSouth at Cingular's
         request of a Patent.

7.       EXTENSION OF TM AGREEMENT. BellSouth hereby extends the date pursuant
         to which Cingular may use the BellSouth Marks under the TM Agreement
         until December 31, 2001.

         IN WITNESS WHEREOF, the parties hereto acknowledge that this Agreement
shall be deemed effective as of the day and date first above written.

                  A.       Licensor owns or otherwise has marketing rights in

         2.1      License. In consideration of Licensee's obligations set forth
in this Agreement and other agreements being executed by SBC and BellSouth on
or about the Closing Date, Licensor hereby grants to Licensee a perpetual,
fully paid-up, royalty-free, nonexclusive right and license (with limited

Products, (3) to practice the Licensed Processes, (4) to sell Licensed Services

<PAGE>

         2.3      No Future Licenses. Nothing herein shall be construed to
require that Licensor license any Other Intellectual Property to Licensee.

         2.4      No Implied Licenses. The license and rights granted in this
Agreement to Licensee from Licensor shall not be construed to confer any rights
upon Licensee by implication, estoppel or otherwise as to any technology not
specifically identified in this Agreement as Licensed Technology, nor shall it
be construed to confer any rights outside the Territory.

3.       Infringement.

         3.1      Enforcement of Rights to Licensed Technology. Licensee shall
promptly advise Licensor, in writing, upon becoming aware of any infringement
or threatened infringement of any of the Licensed Products in the Territory or
any claim that the Licensed Products infringe the Intellectual Property rights
of another party in the Territory. Licensor shall have the initial right to
determine the appropriate action, if any, to be taken with respect to any such
infringement. If Licensor or an Affiliate initiates an enforcement suit or
proceeding or intervenes to defend any claim of infringement of the right of
another, it shall have the right to exclusive control of any such suit or
proceeding (provided, however, that Licensee shall remain a party to such suit
to the extent so required). Licensee shall cooperate with Licensor with respect
to any such proceedings, including, without limitation, joining as a party to
any litigation, if required. If, on request by Licensee, Licensor refuses to
pursue infringers within a reasonable time, Licensee shall be entitled to take
reasonable appropriate actions to challenge such infringement at its own
expense. If Licensee institutes suit pursuant to this Section 3.1, Licensor
shall (i) provide reasonable assistance to Licensee and (ii) have the right to
participate and represent its interests through other counsel of its own
choosing and at its own cost. In addition, in no event shall Licensee have the
right, without the prior consent of Licensor, to acknowledge the validity of a
claim that the Licensed Products infringes the Intellectual Property rights of
another party, to obtain or seek a license from such party or to take any other
action which might impair the ability of Licensor to contest the claim of such
party if Licensor so elects. Licensee agrees at the request of Licensor to make
and have made reasonable modifications requested by Licensor in Licensee's use
of the elements of the Licensed Products in question or so long as such
modifications would not have a material adverse effect on Licensee if Licensor,
in its sole discretion, reasonably exercised, determines that such action is
necessary to resolve or settle the claim or suit or eliminate or reduce the
threat of a claim or suit by such party.

         3.2      Cooperation. In any proceedings that Licensor may commence or
defend pursuant to its rights under this Agreement in order to enforce or
defend the validity or enforceability of the rights to Licensed Technology,
Licensee shall, at the request and expense of Licensor, cooperate in all
respects and, to the extent possible, have its employees testify when requested
and make available relevant records, papers, information, samples, specimens
and other information sought in discovery.

4.       Confidentiality.

         4.1      In the event of the termination of this Agreement, Licensor
and Licensee, each at its own expense, shall promptly deliver (without
retaining any copies thereof) to Licensee or

                                       3
<PAGE>

Licensor, as the case may be, or confirm to the other in writing that it has
destroyed, all information furnished to it or its representatives by the other
or any of the other's Subsidiaries or any of their respective agents, employees
or representatives as a result hereof or in connection herewith, whether so
obtained before or after the execution hereof, and all analyses, compilations,
forecasts, studies or other documents prepared by it or its representatives
which contain or reflect any such information. Licensor and Licensee shall, and
shall cause their respective employees, officers, directors and Subsidiaries
and the employees, officers and directors of their Subsidiaries to, subject to
any exceptions set forth in the Confidentiality Agreement (as defined below),
cause any information so obtained to be kept confidential and will not use, or
permit the use of, such information in its business or in any other manner or
for any other purpose except as contemplated hereby.

         4.2      In addition to the confidentiality arrangements contained
herein, all information provided or obtained in connection with the
transactions contemplated by this Agreement (including pursuant to Section 4.1
above) shall be held in accordance with and subject to the terms of the
Confidentiality Agreement, dated February 18, 2000, between SBC and BellSouth
(the "Confidentiality Agreement"). In the event of a conflict or inconsistency
between the terms of this Agreement and the Confidentiality Agreement, the
terms of this Agreement shall govern.

5.       Representations.

         5.1      Licensor. Licensor represents and warrants that it is the
owner or licensee of the Licensed Technology and that Licensor has the right to
grant to Licensee the licenses contemplated under this Agreement. Licensor
further represents and warrants that it has the right to enter into this
Agreement, that it has not granted any outstanding conflicting rights, and that
it has not made, nor will it make, any commitment to any third party
inconsistent with or in derogation of the rights granted hereunder.

6.       Miscellaneous and General.

         6.1      Entire Agreement. This Agreement constitutes the entire
agreement between Licensor and Licensee with respect to the Intellectual
Property licenses which are the subject matter hereof and supersedes all
promises or understandings made prior to or contemporaneously herewith with
respect to such subject matter.

         6.2      Headings. The section and paragraph headings are for
convenience only and are not a part of this Agreement.

         6.3      Severability. All rights and restrictions contained herein
may be exercised and shall be applicable and binding only to the extent that
they do not violate any applicable laws and are intended to be limited to the
extent necessary so that they will not render this Agreement illegal, invalid
or unenforceable. If any provision or portion of any provision of this
Agreement not essential to the commercial purpose of this Agreement shall be
held to be illegal, invalid or unenforceable by a court of competent
jurisdiction, the remainder of the Agreement shall be interpreted to the extent
possible to effect the overall intention of the parties at the Effective Date
of this Agreement.

altered in any way, except in an amendment identified as such and signed by
both Licensor and Licensee.

         6.5      Non-waiver. The waiver of any breach of any provision of this
Agreement shall not be deemed to be a waiver of any other breach of the same or
any other provision of this Agreement.

         6.6      Non-Agency. Nothing contained in this Agreement or the
performance thereof is intended to or shall be construed to create any
relationship of agency, partnership or joint venture between Licensor and
Licensee.

                  substantially all of the assets of the relevant business of
                  either Licensee or Licensor, provided that the assignee is
                  obligated to fulfill any and all obligations of its
                  predecessor in interest hereunder.

                  (b)      Other. Except as provided in Section 6.7(a) above,

                  Any purported assignment without such permission(s) shall be
