                                  MASTER TERMS

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Company and BellSouth,
hereby agree as follows:

A. SCOPE AND PURPOSE

         The purpose of this Agreement is to establish a mutually beneficial
[***] relationship between BellSouth and Company ("Relationship"). The
elements of the Relationship are set forth in the following exhibits, which are
attached hereto and incorporated into this Agreement:

         1. Exhibit A, pursuant to which the parties will engage in cooperative
            promotional activities related to the Relationship;

         2. Exhibit B, which is reserved for possible future use;

         3. Exhibits C and D, pursuant to which the parties will engage in
            [***] to each other.

         This Agreement shall not create a legal representative or agency
relationship between the parties. No party shall have the right or authority to
assume, create, or incur any liability or obligation of any kind, expressed or
implied, against, or in the name of, or in the behalf of the other party. No
party shall have any power or authority to bind or commit the other party.
Nothing contained in the Agreement shall be deemed or construed as creating a
joint venture or partnership between the parties. No party shall have the power
to control the activities and operations of any other party.

         Each party's relationship to the other party in the performance of this
Agreement is that of an independent contractor. Personnel furnished by a party
("Party's Employees") to perform services hereunder shall at all times remain
under that party's control and direction and shall be employees solely of that
party. That party shall pay all wages, salaries and other amounts due its
employees relative to this Agreement and shall be responsible for all
obligations respecting them relating to FICA, income tax withholdings,
unemployment compensation and other similar responsibilities. In the event that
a party's independent status is denied or changed and that Party's Employees are
declared to be "common law" employees with respect to work performed for another
party, to the extent permitted by law, the employing party agrees to hold
harmless from all taxes and costs, including reasonable attorneys' fees, as set
forth above, that any other party may incur as a result of such change in
status. Moreover, solely for purposes of complying with the Immigration Reform
and Control Act of 1986 and its regulations ("IRCA"), each party warrants and
agrees to the other party that, to the best of its ability, it will (i) not
assign any individual to perform work hereunder who is an unauthorized alien
under IRCA, (ii) immediately remove any alien discovered to be unauthorized from
such work and replace him/her with one who is not an unauthorized alien, and
(iii) to the extent permitted by the law to indemnify and hold the other party
harmless from all liabilities, damages, losses, or expenses and reasonable
attorneys' fees arising out of a breach of this clause.

B. ADDITIONAL BUSINESS RELATIONSHIPS

         Company will discuss with BellSouth opportunities to [***]

C. ADVERTISING AND PUBLICITY

         The parties shall develop a mutually acceptable press release
concerning the subject matter of this Agreement. The parties may also prepare
other mutually acceptable public relations materials relating to this Agreement.
All media releases, public announcements and public disclosures by either party
regarding the Relationship shall be coordinated between and approved by both
parties prior to release. Such approval shall not be unreasonably withheld or
delayed by either party.

D. CONFIDENTIAL INFORMATION

         Each party acknowledges that it may acquire information and material
that is the other party's confidential, proprietary or trade secret information.
As used herein, "Information" means all information and documents disclosed by a
party, whether written or oral, in the course of this Agreement or in
contemplation hereof, that is marked "confidential", "proprietary", or "trade
secret" or, if disclosed orally, is characterized as such and confirmed in
writing as such a reasonable time after disclosure, and shall include all

agents, subcontractors or other suppliers received from the party.

         The receiving party agrees to take all steps reasonably necessary to
hold in confidence disclosing party's Information, not to disclose it to third
parties or to use it, in any way, commercially or otherwise, other than as
permitted under this Agreement. The receiving party will limit the disclosure
of the disclosing party's Information to employees, subcontractors, agents,
representatives and other third parties with a need to know who perform under
this Agreement who (i) have been advised of the proprietary nature thereof and
(ii) have been contractually obligated to maintain such confidentiality. The
receiving party's obligations set forth herein shall remain in effect for two
(2) years from the receipt of disclosing party's Information considered or
deemed to be confidential information, but such obligation of disclosing party's
confidentiality will not expire for disclosing party's Information considered or
deemed to be a trade secret under applicable law.

         Notwithstanding the other provisions of this Agreement, nothing
received by either party from the other will be considered to be the disclosing
party's Information if (i) it has been published or is otherwise available to
the public other than by a breach of this Agreement, (ii) it has been rightfully
and lawfully received by the receiving party from a third party without
limitations or restrictions on its use or disclosure, (iii) it has been
independently developed by the receiving party or by personnel having no access
to disclosing party's Information, (iv) it was known by the receiving party
prior to its first receipt from the disclosing party and such knowledge can be
substantiated by reasonable documentation, (v) it is hereafter disclosed by the
disclosing party without restriction on further disclosure, or (vi) it is
required to be disclosed to any governmental agency or a court of competent
jurisdiction pursuant to a written order, subpoena or by operation of law,
provided the receiving party has given the disclosing party prior advance
written notice in order that the disclosing party may attempt to obtain a
protective order limiting disclosure and use of the information disclosed.

         Each party hereby agrees that every individual person including but not
limited to employees, subcontractors, agents, representatives and other third
parties who perform under this Agreement shall execute the appropriate documents
to undertake obligations of confidentiality and limitations on use consistent
with the terms set forth herein. Each party hereby agrees to provide evidence of
such duly executed documents and/or copies to the other upon request.

E. PRIOR COMMITMENTS

         The parties represent that neither of them is negotiating to enter into
any legal commitment(s) or is under any prior legal commitment(s) that would
interfere with the good faith performance of this Agreement, except such
commitments as have been disclosed to the other party on Exhibit E hereto.

F. NON-EXCLUSIVE AGREEMENT

         This Agreement does not create an exclusive relationship between the
parties. Either party may freely contract with other parties for comparable or
identical relationships.

G. INTELLECTUAL PROPERTY

         Except as specifically provided herein, no licenses under any patents,
copyrights, trademarks, trade secrets or any other intellectual property,
express or implied, are granted to either party under this Agreement.

H. FORCE MAJEURE

         Neither party shall be responsible for any delay or failure in
performance of any part of this Agreement to the extent that such delay or
failure is caused by fire, flood, lightning, explosion, war, strike, embargo,
government requirement, civil or military authority, act of God, acts or
omissions of carriers, or other similar causes beyond its reasonable control. If
any such condition occurs, the party delayed or unable to perform shall give
notice to the other party as soon as possible.

O. INDEMNIFICATION

         The parties agree to the following indemnification provisions that
arise out of their respective capacities:

         (1) With respect to matters of liability that relate directly to use of
the products or services of either party provided as the result of a referral
under this Agreement, the providing party agrees to indemnify and save harmless
the other party from any liabilities, lawsuits, penalties, claims or demands
(including the costs, expenses and reasonable attorney's fees) that may be made
by any third party for (a) injuries (including death) to persons, (b) physical
damage to real or tangible property (excluding software or data) resulting from
alleged defects in such products or services, or (c) breach of warranties.

         (2) With respect to matters of liability that do not relate directly to
use of the products or services, each party shall indemnify and save harmless
the other party from any liabilities, lawsuits, penalties, claims or demands
(including the costs, expenses and reasonable attorney's fees) that may be made
by (a) any third party for injuries (including death) to persons or physical
damage to real or tangible property (excluding software or data) that solely
results from the other party's negligent or willful acts or omissions or those
of persons furnished by either party, its agents or subcontractors or (b) any
employee or former employee of either party or any of its subcontractors for
which the other party or its subcontractor's liability to such employee or
former employee would otherwise be subject to payments under the state Worker's
Compensation or similar laws.

         Each party agrees to notify the other promptly of any written claims or
demands for which it is responsible hereunder. The indemnifying party shall
defend or settle, at its own expense, any action or suit against the indemnified
party; provided, however, that the indemnifying party shall not settle any such
action or suit in a manner that imposes any obligation on the indemnified party
without the prior written consent of such party, which consent shall not be
unreasonably withheld. The party seeking indemnification shall notify the other
party promptly of any claim for which the indemnifying party is responsible and
shall cooperate with such party in every reasonable way to facilitate the
defense or settlement of any such claim.

WARRANTIES, FAILURE OF ESSENTIAL PURPOSE OR OTHERWISE, SHALL BE LIMITED TO THE
LESSER OF (1) THE FEES PAID FOR THE REFERRAL OUT OF WHICH THE LIABILITY ARISES
OR (2) $100,000; PROVIDED, HOWEVER, THAT THE FOREGOING SHALL NOT LIMIT A PARTY'S
LIABILITY UNDER THIS AGREEMENT FOR PAYMENT OF THE FEES DUE HEREUNDER, OR CLAIMS
