determining the extent to which the Performance Goals are met and Awards are

         requirements of Section 162(m) of the Code, Awards payable to Covered
         Employees after such time shall constitute "qualified performance-based
         compensation" and shall be subject to the achievement of an overall
         performance goal based on Consolidated EBITDA in order that payments
         are deductible under Section 162(m) of the Code.

         (2)      In the event the Company becomes subject to the provisions of
         Section 162(m) of the Code, Awards payable after such time to Covered
         Employees shall only be payable under this Plan for a Plan Year if the
         Company has positive Consolidated EBITDA for the Plan Year.

         a Plan Year (i) to a Covered Employee who is the Chief Executive
         Officer for any part of the Plan Year, and (ii) to each other Covered
         Employee will be (i) 0.5% and (ii) 0.3%, respectively, of Consolidated
         EBITDA for the Plan Year. This resulting amount for any Plan Year shall
         be the limit established for purposes of Section 162(m) of the Code,
         and the actual amount paid to any Executive shall only be that amount,
         if any, determined by the Administrator under Sections 6.1 and related
         sections of the Plan.

         (3)      In the event that Awards payable to any Covered Employee
         become subject to the limitations of Section 6.1(f)(2) above, the

         paid under Section 6.1(f)(2) for the Plan Year to any

7.0      Miscellaneous Administrative Provisions.

7.1.     Amendment and Termination. The Administrator shall have the unilateral
right to amend, modify, suspend or terminate the Plan at any time for any
reason; provided, that in the event Section 162(m) is applicable, approval by
shareholders shall be required as provided in the regulations under Section
162(m) of the Code for any amendment that would have the effect of changing the
class of employees eligible for consideration for Awards under Section 5.0,
materially changing the definition of Consolidated EBDITA, changing the formula
in Sections 6.1(f)(2) and 6.2(h) for determining the maximum amount of Grants or
Awards paid to any Executive or changing the provisions of Section 6.1(g)
regarding the credit of additional amounts on deferred Awards.

7.2.     Beneficiary . A Participant may name, from time to time, any
beneficiary or beneficiaries (which may be named contingently or successively)
as his or her Beneficiary for purposes of the Plan. Each designation shall be on
a form prescribed by the Administrator, will be effective only when delivered to
the Company, and when effective will revoke all prior designations by the
Participant. If a Participant dies with no such beneficiary designation in
effect, or if the Administrator determines that there is any question about the
legal right of the designated beneficiary , such Participant's Beneficiary shall
be his or her estate. The Administrator shall set forth additional rules and
requirements regarding the rights of Beneficiaries to receive payment of an
Award or exercise a vested SA Unit following the Participant's death.

7.3.     No Right to Awards. No person shall have any claim to receive a Grant

of treatment of eligible Participants under the Plan. The selection of a
Participant to receive Grants or be paid Awards and the amount and payment of
Awards rests completely in the absolute and final discretion of the
Administrator. The Administrator's discretion is limited only by the maximum
amount of a Grant or Award that it may pay as provided in Sections 6.1(f)(2) and
6.2(h), if applicable. Neither the existence of this maximum, nor any prior
practice by the Administrator as to the

and shall not lessen or affect the Company's or Subsidiary's right to terminate
the employment or service of such Participant. No Participant or other Person
shall have any claim to be granted any Award, and there is no obligation for
uniformity of treatment of Participants, or holders or beneficiaries of Awards.
The terms and conditions of Grants and Awards and the Administrator's
determinations and interpretations with respect thereto need not be the same
with respect to each Participant (whether or not such Participants are similarly
situated).

7.5.     No Funding. This Plan shall be unfunded and no assets of the Company or
a Subsidiary shall be segregated for the purpose of paying any Awards.

7.6.     Taxes or Deductions. The Company or any Subsidiary shall withhold from
any payment under the Plan such taxes as it deems are sufficient to cover any
withholding taxes that may become required with respect to such payment. The
Company or any Subsidiary shall have the right to require the payment to it of
any such taxes and require that any person furnish information deemed necessary
by such company to meet any tax reporting obligation before making any payment
under the Plan. The Company shall also withhold any other authorized or required
amounts or deductions.

7.7      Other Incentive Plans. Nothing in this Plan shall prevent the Company
and its subsidiaries from maintaining other incentive compensation plans
providing for the payment of incentive awards to employees, provided that the
requirements of Section 162(m), if applicable, are met by the Company in the
administration and operation of such other plans.

7.8      Company Benefit Plans. The terms of the Company's benefit plans shall
determine whether Awards are included as compensation or earnings under the
particular benefit plan.

7.9      Governing Law and Venue. This Plan and all related documents shall be
governed by the laws of the State of Georgia, without regard to the conflict of
laws provisions thereof (except to the extent provisions of federal law may be
applicable). Acceptance of a Grant shall be deemed to constitute consent to the
jurisdiction and venue of the Superior Court of Fulton County, Georgia and the
United States District Court for the Northern District of Georgia for all
purposes in connection with any suit, action, or other proceeding relating to
such Grant or a corresponding Award, including the enforcement of any rights
under this Plan or other document, and shall be deemed to constitute consent to
any process or notice of motion in connection with such proceeding being served
by certified or registered mail or personal service within or without the State

                                EXECUTIVE SUMMARY

BELLSOUTH ("BST") BILLING AND COLLECTIONS AGREEMENT

Cingular and BST have agreed to enter into a new Billing and Collections
Agreement ("B&C") that will supercede the existing Billing and Collections
agreement. The B&C outlines the billing and collection processes between the two
companies and the associated costs to perform those services. The B&C is
effective as of September 1, 2003 and has a term of 3 years. Thereafter, the
term shall continue on a monthly basis until either a new agreement is in place,
or until the agreement is amended. The B&C is effective for all BST Markets
where Combined Billing is available.

The pricing for the B&C costs to be charged to Cingular will have an average
cost of a $1.13 per invoice. This cost including OCA charges (Outside Collection
Agency) is approximately $1.40 per invoice. For comparative purposes, Cingular's
internal B&C costs plus OCA fees is $1.22.

The bad debt under this agreement will now be fully recoursed, beginning with
the September PARS Statement, which corresponds to the December 2002 revenue
month. Under the previous agreement, bad debt was withheld at 3.2% each month.
The new B&C provides for full recourse of the actual bad debt incurred by BST.
BST and Cingular have agreed on two provisions to aid in the management of bad
debt. First, BST will use Cingular's credit scoring model. Second, BST and
Cingular will meet quarterly to review and modify collection procedures.

--------------------------------------------------------------------------------

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT

This agreement ("Agreement") is entered into by and among BellSouth
Telecommunications, Inc., a Georgia corporation (herein referred to as "BST"),
and Cingular Wireless LLC. (Cingular), a Georgia corporation, (herein referred
to as "Client"), to be effective the first day of September, 2003. Client and
BST are hereinafter collectively referred to as the "Parties". Client shall
purchase Service as described in this Agreement including Attachment Number 1
for a period of three (3) years from the effective date of the contract.

WHEREAS, BST offers certain billing and collections services pursuant to the
Agreement; and

WHEREAS, Client desires to avail itself of those services as more particularly
described below:

NOW, THEREFORE, in consideration of the terms and conditions contained herein,
BST and Client hereby mutually agree as follows:

1.       SCOPE OF THIS AGREEMENT AND RELATIONSHIP TO OTHER DOCUMENTS

         A.       It is expressly understood and acknowledged that the service
                  (the "Service") which is the subject of this Agreement is
                  provided solely pursuant to and under the terms, conditions,
                  rates and charges as set forth in the Agreement and Attachment
                  One (1) which is hereby made a part of this Agreement.

         B.       Any services offered by BST to or for Client for which terms
                  and conditions, including rates, are not specifically
                  established herein may be offered on an Individual Case Basis
                  ("ICB") for which necessary additional terms and conditions,
                  including rates, shall be negotiated separately. The Parties
                  may amend the Agreement to provide for such services, which
                  shall then be governed by this Agreement. Any such amendment
                  shall be in writing and signed by both parties.

2.       ENTIRE AGREEMENT

         The Agreement, together with all amendments and attachments hereto,
         constitutes the entire agreement between Client and BST, which
         supersedes all prior agreements or contracts, oral or written
         representations, statements, negotiations, understandings, proposals
         and undertakings with respect to the subject matter hereof.

3.       HEADINGS

         This Agreement or any part hereof or any attachments hereto may not be
         modified or amended except by written agreement signed by or on behalf
         of both Parties. No waiver or consent to any default under this
         Agreement shall be effective unless the same shall be in writing and
         signed by or on behalf of the Party against whom such waiver or
         consent is claimed. In addition, failure to strictly enforce any term,
         right or condition of this Agreement shall not be construed as a waiver
         of such term, right or condition.

5.       REGULATORY CONSIDERATIONS

         If any regulatory authority of competent jurisdiction should determine
         that any or all of the services offered pursuant to this Agreement
         cannot be provided as untariffed, unregulated services, this Agreement
         shall have no further force or effect and BST shall have no further
         duty to perform the affected Service under this Agreement. If in such
         instance BST, in its sole discretion, shall decide to tariff a
         regulated service, Client may elect to obtain such service pursuant to
         the approved tariff. If Client elects to continue the service on or
         after the effective date of the tariff, all terms and conditions in the
         tariff shall apply, and provision of the service by BST shall be
         governed solely by said tariff.

6.       GENERAL DESCRIPTION OF SERVICES TO BE PURCHASED

         A.       SERVICE DESCRIPTION

         Combined billing is a single bill containing charges for both BST and
         the Client, provided to End-Users subscribing to both BST and Client
         services. Based on End-User request for combined billing, the Client
         shall provide to BST an invoice containing the Client charges/credits,
         associated taxes, and informational text for products and services
         listed in Section 6.B. below for billing to authorized BST End-Users.
         An authorized BST End-User (hereinafter known as the "End-User") is the
         responsible billing party that has agreed to purchase services from the
         Client and also purchases telephone service from BST. The Client will
         also provide to BST Adjustments for Client charges appearing on the
         Client's bill pages. BST will edit the invoices and Adjustments and
         bill error-free invoices to such authorized BST End-Users. BST will
         perform treatment and collections services on behalf of the Client for
         such invoices. BST may involve outside collection agencies for
         collection of Client revenues.

         The Client may initiate transactions for validation that the BST
         End-User account information matches Client billing information,
         confirming that Client invoices should be included in the bill for BST
         services.

         Under this Agreement, BST shall provide Billing and Collection Services
         for Client charges and credits submitted by invoice and Adjustments
         through BST's Flexible Invoicing System for Host Carrier Identification
         Code ("CIC") ACOO and Traffic CICs AC01 and AC11.

                                                                               4

         Billing and Collection Services for other Entity Code(s) representing
         Cingular Wireless shall be pursuant to either an addendum to this
         Agreement or a separate Agreement.

         B.       PRODUCTS/SERVICES BILLED BY CLIENT

         Under this Agreement, the Client can bill charges/credits associated
         with the following products and services:

                  1).      Wireless services, associated End-User equipment and
                           accessories, applicable taxes and/or interest,
                           Adjustments, refunds of deposits and early contract
                           termination charges.

                  2).      The charges/credits associated with the above
                           products and services are referred to as "charges".
                           The Client will provide BST with an invoice
                           containing all charges, associated taxes, and related
                           text information for a given End-User.

                  3).      Under this Agreement, the Client can only bill
                           charges associated with services and products
                           provided by the Client, either directly or by resale.
                           Such billing may include amounts for approved
                           services provided by third parties but related
                           specifically to the service provided the End-User by
                           Client, with services approved through the process
                           described in Section 14.A.

7.       END-USER AUTHORIZATION AND IDENTIFICATION

         A.       The Client shall bill charges to current (live) BST End-Users
                  and End-Users who have disconnected their BST service and
                  remain on the customer tollguide database. BST is not
                  obligated to send charges to End-Users that have disconnected
                  their BST service and have been deleted from the customer
                  database. BST agrees, under normal circumstances, to maintain
                  disconnected accounts on the customer toll guide database for
                  a minimum of 61 days. BST will not establish an End-User
                  account solely to render Client Charges.

B.       It is the responsibility of the enrolling Party to ensure that
                  the End-User of record of the BST account agrees to accept
                  billing responsibility for the Client's charges to be included
                  on the BST bill. Only charges for End-Users who have accepted
                  the terms and conditions of the Client service, including the
                  combined billing, will be sent to BST for billing. Where
                  required by regulatory mandate, BST will not allow combined

                  that has requested that a third-party billing block be placed
                  on their wireline account.

         C.       The Client is responsible for maintaining the BST Billing

EXHIBITS - Billing and Collections Services Operating Agreement by and among
           BellSouth Telecommunications, Inc. and Cingular Wireless LLC,
           effective September 1, 2003

                                                                   EXHIBIT 10.62

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                         BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

                  is different from BSTs. Multiple invoices for different Client
                  customers and Client accounts may be billed to the same BST
                  wireline End-User account.

         D.       Client agrees that charges for services it has rendered will
                  be sent to BST only one time for inclusion in End-User bills,
                  except those charges that were rejected by BST as Unbillable
                  due to error and are being resent by Client. Duplicate charges
                  will not be sent by the Client to BST for billing. However,
                  BST will continue to bill customers in conformity with terms
                  and conditions herein for past-due amounts.

         E.       BST will provide, when available, the End-User billing name,
                  address, social security number or Federal Tax ID and the
                  billing telephone number associated with the wireline
                  telephone number provided to associate the Client invoice with
                  the End-User wireline bill. This information will be
                  associated with the Billing Telephone Number (BTN) on which
                  the wireline bill is rendered. Client agrees that this data
                  will not be used by Client for any purposes other than the
                  billing of Client's customers. BST will mechanically notify
                  Client of changes to the BTN and End-User billing name and
                  address after they occur, in the normal course of business. It
                  is the responsibility of the Client to correct Client records
                  to reflect the new End-User BTN for any subsequent invoices
                  sent to BST.

         F.       Certain BST wireline accounts are ineligible for Client
                  combined bill arrangement. Those include but are not limited
                  to BST accounts for the following: BST Reseller, Coin Phone
                  Service, BST Official, Foreign Exchange, and Independent
                  Company, WATS, and other accounts not yet determined to be
                  mutually agreed upon at a later date. These accounts will be
                  identified to Client as ineligible in the Landline Telephone
                  Number Validation ("LLTNV") process and any invoices sent on
                  these accounts will be rejected. BST will also reject data
                  sent by the Client for disconnected accounts that are no
                  longer on the Customer toll guide database.

         G.       Both parties are responsible for explaining to perspective
                  End-Users any eligibility or enrollment denials resulting from
                  their company's enrollment procedures. If combined billing is
                  not possible, the Client will be responsible for billing its
                  charges to the End-User directly.

8.       DATA FORMAT AND CONTENT

         The Client and BST will exchange data that is formatted according to
         mutually agreed upon specifications. If changes are required to these
         specifications, BST will notify Client at least ninety (90) days before
         targeted implementation. Both parties agree to implement these changes
         in the mutually agreed upon timeframe. The Client agrees to pay BST for
         implementation of any customized format changes requested by Client If
         a BST proposed format specification revision requires a change to
         Client systems, responsibility for paying for such revision will be
         handled on an ICB.

                                                                               6

--------------------------------------------------------------------------------

         Client will pass End-User charges to BST via the Flexible Invoicing
         Service ("FLEX") for inclusion on BST's bill.

9.       DATA EXCHANGE

         BST supports the use of electronic data transmission (e.g. Sterling
         Commerce's CONNECT:Direct(TM)) for data delivery. CONNECT:Direct(TM)
         electronic data transmission is the primary data exchange method. Data
         transfer via cartridge will be used as the backup/alternate data
         delivery method when electronic data transmission cannot be used. The
         specific data delivery method such as cartridge size or electronic data
         transmission version must be a method that can be supported within
         BST's and Client's data processing centers. Client and BST must
         mutually agree on the use of a backup/alternate delivery method if
         needed.

         Dates and times for data exchange will be negotiated and agreed upon by
         both Parties. Any changes required for the data exchange process must
         be coordinated between the Parties and should allow sufficient time for
         the agreed upon changes to be tested and implemented. Receipt of data
         files will automatically start the processing of the Client's data. BST
         will not change its End-User bill period to accommodate Client's
         billing schedule.

         The software for electronic data transfer and the physical line
         location will be negotiated and agreed upon by both Parties. When a
         dedicated line is used, the Client will be responsible for ordering and
         purchasing the data transmission circuits, any additional hardware and
         paying all costs associated with installation and usage charges. The
         Client will be responsible for providing the telephone line and modem
         to transmit data to BST. Should a non-standard modem be required on the
         BST end, the Client must obtain, purchase, install, and maintain this
         equipment and assumes all associated maintenance charges. Since the
         equipment is in a secure area, access for the purpose of maintenance
         must be arranged with BST in advance.

         Upon receipt of the Client's data, BST will verify through the
         mechanized editing of the file that the total transmission reported by
         the Client is the total received and entered into the BST Billing
         System. BST's control of the Client's data will begin upon receipt of
         the data at the BST processing location.

         BST will determine whether the data can be processed and provide
         confirmation of receipt of the data to the Client. If the Client uses
         electronic data transmission, (the normal mode of file delivery), BST
         will provide transmission confirmation reports within 24 hours after
         the data has been processed. If the Client must use the alternate mode
         of data delivery, BST will either send the confirmation reports and
         files via the restored CONNECT:Direct(TM) connection within twenty four
         (24) hours, fax, or mail a copy of the confirmation reports to the
         Client on the next business day following processing of the data.

         In the event BST cannot process a Client file due to a data
         transmission system failure, improperly formatted data on the file, or
         other reasons caused by the Client, the Client will make every effort
         to re-send the data upon correction of the problem. BST will not be
         responsible for data that cannot be processed due to Client error.

                                                                               7

             BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                        BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

         The Client will retain a copy of the data sent to BST for 60 days.
         Failure of the Client to retain a copy of this data for at least 60
         days will abrogate BST liability as set forth in this section and in
         Section 11.

         BST will retain a copy of the data sent to the Client for 60 days. In
         the event the Client loses or is unable to process this data, the
         Client can request BST to re-send the data. The first request will be
         done at no charge; however, subsequent requests to re-send the same
         data will be handled on an ICB.

10.      ERRORS AND OMISSIONS

         If the Client discovers a Client-generated error, the Client will
         notify the BST designated contact by phone immediately and follow up in
         writing {FAX or E-mail) as soon as possible. Any action required by BST
         will be handled on an ICB and any cost incurred by BST for data
         recovery will be billed to the Client. Such recovery may include
         extracting data awaiting billing and correcting system impact.

         If BST finds or is notified of a BST error on an End-User's bill, it
         will make every reasonable effort to correct the error and bill
         correctly within the limits permitted by laws of the state in which the
         service is provided. Enrollment billing disputes will be handled as
         outlined in Section 16. BST will notify the Client in writing of a
         BST-generated error and corrective action.

11.      LOST OR DAMAGED DATA

         If BST loses or damages the Client's data, BST will make every effort
         to recover and re-process the data. If BST is unable to re-process the
         data, BST will, as soon as possible, notify Client in writing to
         re-send the data to BST. The Client will re-send the data to BST within
         48 hours (or 2 business days) of notice of request by BST.

         BST requires the use of the incremental pack sequence number for data
         packs to ensure data files are processed correctly and will control
         data files using the sequence number. The Client is required to repack
         and increment the pack sequence number and resend packs/files to BST,
         when the pack/file has been rejected as being a duplicate or out of
         sequence. BST will not be responsible for handling out-of-sequence
         packs for invoices, adjustments or text files (packs within the file).

12.      REJECTED INVOICES AND ADJUSTMENTS

         Standard reports, listing all invoices and/or Adjustments that have
         been received from the Client, but rejected by BST will be provided to
         the Client. A reject reason will be provided for each invoice and/or
         adjustment. If the invoice or adjustment is rejected due to Client
         error, notification will be sent at the same time as the confirmation
         file is sent via the error report. All errors will be listed for each
         record on this report. Each invoice and/or adjustment will be reported
         on the Unbillable report with a return code or reason code noted.

                                                                               8

         Also, on the Unbillable report are the Unguideables. Unguideables will
         be reported with a unique return code(s). All rejected/unguidable
         invoices and/or adjustments are returned via the Unbillable file.
         Invoices rejected by BST due to Client formatting error may be
         corrected and re-sent to BST in a subsequent data exchange cycle. It
         will be the responsibility of the Client to secure alternate billing
         for the invoices that cannot be billed by BST (e.g. Unguideables).

         If data pack (file) contains greater than a 5% error rate for invoices
         or adjustments, the entire pack will be returned to Client and shall
         not be accepted or purchased by BST. The other packs within the file
         will be accepted if error threshold is not exceeded. The file will be
         processed except for the bad packs. After correction, the data pack
         (file) may be resequenced and resent to BST.

13.      BILL SPECIFICATIONS

         Charges billed by BST for the Client will appear on a separate bill
         page with the Client logo (symbol and text) and Client's End-User
         service number within the End-User's BST bill. Client's logo will
         appear on every bill page containing Client charges. Only Client billed
         charges may appear on these pages containing Client's logo.

         Subject to Section 30, Client agrees to provide BST a logo image and to
         obtain any necessary authorizations or licenses for the use of any logo
         it asks BST to print. Also subject to Section 30, Client agrees to
         indemnify, defend and hold BST and its affiliated companies harmless
         against all claims, suits, costs, damages, expenses, attorneys' fees
         and judgments arising out of or alleged to arise from BST printing the
         logo and its inclusion on the End-User bill.

         The bill invoice page BST prepares for the Client shall be based on
         mutually agreeable formats. BST is responsible for the overall End-User
         bill format that the Clients invoices are included in. The Clients
         invoice may contain section headings, informational text lines,
         marketing messages and subtotal records. The Client is responsible for
         determining the sequence of the headings, informational text, charges,
         credits and subtotals within each invoice, and for calculating all
         taxes, applying discounts, and determining the total amount due for the
         invoice.

14.      SERVICE AND TEXT APPROVAL

         BST will review and approve any text, marketing messages and service(s)
         the Client requests to have printed on the End-Users invoice. BST may
         reject any text, marketing message, or refuse to bill any service(s)
         that does not conform to reasonable BST requirements. Failure of the
         Client to follow this process and requirement may result in termination
         of this Agreement by BST.

                                                                               9

         which includes new or revised Text Messages, rates, scripts, etc., and
         other required information for approval prior to submitting billing for
         these Services. BellSouth will notify the Client of its approval, or
         denial, of the new or revised Service Program within two (2) weeks of
         receipt of the Client's request. The Service Program approval will be
         submitted to the BST Contract Administrator at least two (2) weeks
         prior to planned implementation of Service Program in a method agreed
         to by both Parties.

         B.       TEXT APPROVAL

         Bill format text wording and phrases which Client wishes to place on
         the BST bill must be submitted to the Bill Continuity Team for approval
         at least thirty (30) business days in advance of their first use on the
         BST bill. Client understands and agrees that BST reserves the right to
         approve and request changes to all words and phrases which Client
         wishes to place on the BST bill. The Client may request BST to modify
         or add additional phrases to be printed on BST's bill. Customized bill
         phrase changes will be handled on an ICB. The Client agrees to pay for
         any changes requested by it. Bill phrases which are associated with tax
         amounts should indicate the tax rate applied by the Client.

         Marketing messages for the Client may be part of the Client invoice
         submitted to BST for inclusion in the End-User bill.

         The Client must submit Marketing message text for approval to BST at
         least thirty (30) business days prior to the first day of the month
         that the marketing message text will be used. BST reserves the right to
         approve and request reasonable changes to all marketing message text
         which the Client wishes to place on the BST bill.

         The Client must submit Marketing message tag lines (FLEX 90 records)
         for approval to BST at least seven (7) business days in advance of
         their first use (transmission to BST) for inclusion on the BST bill.
         BST reserves the right to approve and request reasonable changes to all
         marketing message tag lines (FLEX 90 records) which the Client wishes
         to place on the BST bill. The Marketing Message Tag Lines submitted on
         FLEX 90 records must be appropriately formatted with the tag line
         indicator populated correctly on the record.

         The Client agrees to indemnify, defend and hold BST and its affiliated
         companies harmless against all claims, suits, costs, damages, expenses,
         attorneys' fees and judgments arising out of or alleged to arise from
         BST printing the Client's text messages, bill phrases and marketing
         messages on the End-User bill.

         When BST prints a foreign language (e.g. Spanish) End-User bill in one
         or more of its operating areas, the Client is encouraged to provide the
         invoice text information associated with its charges in the same
         foreign language in which the BST bill pages are printed. The

         Client is responsible for the correct spelling, grammar, editing, and
         special characters of all foreign language text to be printed on the
         End-User's bills.

         If the Client elects to provide foreign language text, Client shall pay
         for all additional program modifications and testing which may be
         required. All such requests to support foreign language text will be
         handled on an ICB. Testing must be completed in FLEX and CRIS before
         the table entry to allow Spanish bill will be updated.

 15.     AGE OF CHARGES

         Client agrees not to send to BST charges more than 90 days old except
         roaming charges. The 90 day age of charge will be based on the date the
         charge was incurred by the End-User compared to the billing date for
         the BST bill on which the Client's charges will be included. Credits
         for charges should be submitted to BST no more than 30 days from when
         the Adjustment was issued by the Client. Should BST receive invoices
         with messages greater than 90 days old, where regulatory rules govern
         age of messages, they will be returned as unbillable.

16.      END-USER DISPUTES

         It is not the intent of the Parties for BST to become involved in
         disputes between Client and its End-Users. In the event an End-User
         contacts BST with a dispute of Client changes and refuses referral to
         the Client Inquiry number, BST will contact the Client via an initial
         SP/BOC Memo, on behalf of the End-User.

         BST will notify the Client of a dispute, within thirty (30) days of
         customer's claim, via an initial SP/BOC Memo, of a dispute. The Client
         has 35 calendar days to resolve the End-User dispute. In the event
         Client sustains, with adequate documentation compliant with BST SP/BOC
         methods and procedures, the amount of the dispute on the End-User
         customer bill (no adjustment warranted), BST agrees to sustain same
         charges upon customer inquiry into BST service centers. If the customer
         then refuses to pay the disputed charges, a final recourse will be
         issued and an SP/BOC will be sent to Cingular as notification. If
         Client sustains disputed Client charges, Client will provide in it's
         substantiation documentation to BST, a description of the action(s)
         taken, result of the investigation(s) and reason(s). If the Client
         fails to respond to BST within the 35 calendar day time frame, BST will
         issue a final SP/BOC Memo to adjust and recourse the amount to the
         Client. If necessary for BST to initiate adjustments to the End-User
         for Client services, and credit for taxes is included, such tax shall
         be calculated by BST based on mutually agreeable procedures with tax
         amounts reported to Client for disposition. In the case that the
         End-User inadvertently receives the same Adjustment more than once,
         the Party responsible for any corrective action will be determined on
         an ICB.

         Unresolved or recurring disputes from an End-User regarding Client
         billing between BST and the Client could result in suspension or
         termination of the combined billing arrangement for that End-User on
         behalf of the Client. If the End-User is removed from the combined

                                                                              11

                                                                   EXHIBIT 10.62

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                         BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

         billing arrangement, the Client is responsible for excluding the
         End-User billing from billing data sent to BST.

         For enrollment disputes where BST or Client initiates combined billing
         to a BST account holder other than the intended End-User, Client
         charges for the given period will be recoursed to Client. BST will make
         every effort to recourse these charges in a timely manner. Client will
         be notified within 90 days from End-User notification to BST of a
         disputed enrollment. If BST fails to notify Client within 90 days of
         learning about the inaccurate billing, BST shall be responsible for any
         incorrectly billed Client charges. If End-User notification to BST of
         an enrollment dispute exceeds 90 days, fraud assessment and profile
         procedures will apply, up to and including recourse of fraudulently
         billed amounts to Client.

         Client-initiated Adjustments to Client charges appearing on the Client
         bill pages will be prepared and entered by Client and will be passed to
         BST via the FLEX adjustment feed. Adjustments submitted by Client will
         be applied to the End-User's wireless charges.

17.      INQUIRY

         The services provided under this Agreement do not include the provision
         of billing inquiry services. For certain End-User accounts with Client
         billing, billing inquiry services may be provided under a separate
         Affiliated Company Agreement. For purposes of this Agreement, the
         billing inquiry service provided under said separate Affiliated Company
         Agreement are viewed as provided by the Client.

         The Client will provide its End-Users with the ability to inquire about
         billed accounts to the Client. Client will provide a toll-free inquiry
         number for any Client charges appearing in a BST bill envelope. If an
         End-User calls BST to ask about Client charges, BST will refer the
         End-User to the Client Inquiry Number. General questions, such as bill
         date, balance, receipt of payment will be answered by BST. Under the
         terms of this Agreement, BST will not have access to detailed
         transaction information or Client rate schedules and will not be able
         to respond to questions of this nature. If an End-User refuses to
         contact the Client, BST will forward the issue to the Client so the
         Client can initiate an End-User contact. The Client will contact the
         End-User as soon as possible after notification by BST.

18.      COLLECTIONS AND TREATMENT

         A.       BST will pursue the single balance due and the charges of both
                  Parties included therein with equal aggressiveness and
                  application of all BST Collection and Treatment resources and
                  processes. In collection amounts due for services provided by
                  the Client, BellSouth, or its contractors or agents, will use
                  its internal Treatment and Collection processes as well as
                  third party collection management efforts in collecting
                  amounts due for Client service charges and Adjustments billed
                  in the BellSouth End-User Bill.

                                                                              12

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                         BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

         B.       "Treatment" is action taken by BellSouth to collect delinquent
                  or unpaid amounts associated with End-User accounts. This
                  action may include, but is not limited to:

                  1). Sending notices/letters,
                  2). Making collection calls,
                  3). Posting payments and Adjustments, and/or
                  4). Negotiating satisfactory payment arrangements with End
                      Users.

         C.       BellSouth collection activities will begin after BellSouth has
                  exhausted Treatment efforts. Collection activity is the
                  referral of End-User accounts with outstanding balances to
                  third party collection management companies. BellSouth refers
                  to a collection management company as an 'Outside Collection
                  Agency' ('OCA'). The OCA charges incurred by BST for the
                  recovery of BST and Client billed revenue will be allocated
                  between the Parties based the percent of BST and Client
                  billed revenue on the identifiable recovered accounts. BST
                  will deduct Client's allocated portion of the OCA Charges from
                  its Settlement amount due, as set forth in Section 22, the
                  month following the month BST pays the OCA for services.

         D.       Additionally, BST will determine if unregulated charges for
                  Client are involved in the balance during the treatment
                  process. When an account comes into treatment, BST will
                  compare the Client's balance as shown on the End-User's
                  Accounts Receivable record established for the account. If the
                  balance exceeds a mutually agreed upon threshold, BST will
                  notify the Client to suspend their End-User's service. After
                  notification from BST, the Client will suspend the End-User's
                  service and notify BST that this has been done.

                  If non-payment of regulated wireline services results in
                  denial of wireline service by BST, and there are Client
                  charges on the same account, BST will notify the Client that
                  BST has taken this action and Client agrees to suspend the
                  Client's End-User's service.

                  BST will notify Client when sufficient payment has been
                  received in order to restore the Client service. Once BST has
                  notified the Client of its receipt of payment, the End-User
                  service must be restored within two (2) hours by Client. The
                  Client shall not restore End-User service without notification
                  from BST that the End-User balance has been satisfied.

         E.       The Parties agree to meet at a minimum on a quarterly basis.
                  The purpose of this meeting includes, but is not limited to
                  examining the relative collections performance experienced in
                  combined billing experienced in this channel compared to
                  performance experienced in Client's Direct billing channel,
                  investigating and managing improvement opportunities, and
                  discussion of current Collections issues. BST agrees to share
                  information on its collection and treatment practices and
                  processes for purposes of identifying improvement
                  opportunities.

                                                                              13

19.      NO DENIAL OF WIRELINE TELEPHONE SERVICE

         Client acknowledges that the Service provided pursuant to this
         Agreement is not related to BST's provision of telephone service to the
         public and that BST cannot and will not disconnect BST End-User's
         services for non-payment of Client charges. Where required by
         regulatory requirements, or Company policy, a statement on the bill
         will clearly indicate to the End-User that failure to pay Client's
         charges will not result in disconnection of regulated telephone
         service.

20.      OPERATING PROCEDURES

         BST will provide the Client with operating procedures for the functions
         associated with the provisioning of this Agreement. These procedures
         include but are not limited to:

         A.  Settlements procedures
         B.  Treatment and Collections
         C.  Data format requirements
         D.  Data exchange procedures
         E.  Management reports

         BST may revise or modify its Operating Procedures from time to time. If
         a BST revision to its Operating Procedures impacts the Clients
         Operating Procedures, such a revision will be mutually agreeable to
         both Companies. If a BST revision to its Operating Procedures does not
         impact the Clients Operating Procedures, Client will be informed of
         such revision and provided the opportunity to comment. When such
         Operating Procedures are revised, the Client will be provided with
         revised documentation.

21.      ACCOUNTS RECEIVABLE

         A.       COMMITMENT TO PURCHASE AND SELL CLIENT ACCOUNTS RECEIVABLE

                  Client agrees to sell, assign and transfer to BST, and BST
                  hereby agrees to purchase from Client, all of Client's right,
                  title, and interest in and to Client Accounts Receivable to be
                  placed on BST's bill in the performance of this Agreement. The
                  purchase of Client Accounts Receivable by BST shall not
                  constitute an assumption or acceptance by BST of any
                  representation, warranty, obligation, or liability of Client
                  with regard to any Client Accounts Receivable, or the Client
                  product or service related thereto. During the term of this
                  Agreement, Client shall sell, assign and transfer to BST and
                  BST shall purchase from Client each and every such Account
                  Receivable to be placed in the BST bill.

         B.       CLIENT ADJUSTMENTS AND REPURCHASE COMMITMENT

                  The Client agrees to repurchase from BST, and BST agrees to
                  sell, assign and transfer to the Client all of BST's right,
                  title and interest in any amount previously billed and
                  purchased by BST which is the subject of a Client Adjustment
                  per the conditions stated herein. The repurchase price shall
                  be equal to the amount of the Client Adjustment. The

                                                                              14

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                         BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

                  repurchase price shall be considered to have been paid by the
                  Client on the Due Date of the Accounts Receivable Settlement
                  Statement which reflects the amount of the Client Adjustment
                  as an element of the Aggregate Purchase Price of the Client
                  Accounts Receivable covered by the Settlement Statement.

                  Dispute adjustments applied by BST are limited as described in
                  Section 16.

                  All Client initiated Adjustments (RTAs) to Client charges
                  appearing on the Client bill pages will be prepared and
                  entered by Client and will be passed to BellSouth via FLEX.

         C.       CLIENT UNCOLLECTIBLE REVENUES

                  BST will purchase the value of the invoices/charges or the
                  Accounts Receivable when the data is received and accepted.

                  After the purchase of the Client's Accounts Receivable, a
                  portion of the same Accounts Receivable may prove to be
                  uncollectible for BST eight to nine months from the date of
                  purchase after all standard treatment and collection
                  activities have been exhausted. In such circumstances THE
                  UNCOLLECTIBLE REVENUE WILL BE RECOURSED IN FULL TO CLIENT
                  THROUGH THE SETTLEMENT PROCESS AS REALIZED NET BAD DEBT. The
                  process from receipt of billing to write-off averages
                  approximately nine ("9") months.

                  These provisions for full recourse of uncollectible revenue as
                  Realized Net Bad Debt will apply to all Client charges and
                  credits submitted by invoice and Adjustments through BST's
                  Flexible Invoicing System for Host Carrier Identification
                  Code ("CIC") AC00 and Traffic CIC's AC01 and AC11. If, in the
                  future, the Parties modify or expand the business
                  relationship and desire to change this term, the Parties
                  agree that such change must be mutually agreed upon in either
                  an amendment to this agreement or in another agreement prior
                  to effecting such change and the Client acknowledges that
                  this may require the establishment of another "CIC".
                  Uncollectibles recourse will begin on the September 2003 PAR
                  statement, (associated with December 2002 revenues), due to
                  the estimated nine-month lag between billing and Net Bad Debt
                  write-off.

                  When Client charges appear on a BST customer bill, the Client
                  amount becomes a part of the "total balance due". If an
                  End-User fails to clear the total balance due, then subsequent
                  bills do not detail the remaining amount due by entity
                  designation ( i.e. BST, Client, etc.).

                  BST procedures allow analysis of the account when and if the
                  account becomes past due or uncollectible. This analysis
                  determines what amounts owing, if any, are due to Client
                  charges based on the billing history of the uncollectible
                  amount. Client charges that become uncollectible are fully
                  recourseable to the Client.

                  Should BST recover any portion of the revenue after it has
                  been written off, BST will share such recoveries with Client
                  based on an apportionment of the actual Client billed revenue
                  on the customer account. BST will pass such recoveries to
                  Client by reducing the realized Net Bad Debt amount for the
                  Settlement reporting period.

                                                                              15

                  End-User makes a partial payment on the total BST balance due.
                  For Treatment purposes only, Regulated services receive
                  payment application prior to unregulated services. Payments to
                  satisfy unregulated balances are apportioned in the same
                  proportion as the percentage of the unregulated balance
                  attributed to each provider, oldest charges receiving payments
                  first. For Net Bad Debt determination, the balance being
                  written off is apportioned in the same proportion as the
                  percentage of the total (regulated plus unregulated) balance
                  attributed to each provider. Net Bad Debt apportionment occurs
                  at the individual end user account level if the billing
                  history is available and at the RAO level if the end user
                  account billing history is not available.

         D.       COLLECTION OBLIGATIONS AFTER RECOURSE

                  BST relinquishes it collection obligations back to Client
                  after BST adjusts a Client charge off an End-User account and
                  recourses the revenue to Client as a post billing adjustment.
                  After BST relinquishes its obligations Client may pursue
                  independent collection activities. Client collection
                  activities will not include any reference to BST other than a
                  statement that such Client charges were initially billed in
                  the BST End-User bill.

                  When BST recourses an Uncollectible amount to Client as
                  Realized Net Bad Debt, BST does NOT relinquish its collection
                  obligations back to Client. Consequently, Client will not
                  pursue any independent collection activities of Realized Net
                  Bad Debt after receipt of the recourse amount.

         E.       REPORTING OF UNCOLLECTIBLE REVENUE TO CLIENT

                  A summary report of the realized uncollectibles will be
                  provided on a standard monthly report and attached to the
                  Purchase of Accounts Receivable ("PAR") statement.
                  Additionally, if desired by Client, BST will provide Client a
                  monthly uncollectible reporting in EMI record format detailing
                  the write offs and recoveries.

22.      SETTLEMENTS AND BILLING AND COLLECTIONS CHARGES

         A.       The Settlement Amount will be calculated as follows:

                  Amount of Client billing charges accepted for the report month
                  -  Total End-User Adjustments for the report month
                  -  Total Unbillable charges for the report month
                  -  Total uncollectibles for the report month
                  -  OCA Expense
                  -  Total Other Charges and Credits for report month
                     ------------------------------------------------
                  =  Net Settlement Amount

                                                                              16

              BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
                         BETWEEN BELLSOUTH AND CINGULAR
--------------------------------------------------------------------------------

         B.       BST will mail the settlement statement in time for it to be
                  received by the Client by the sixteenth (16) workday of the
                  month following close of the report month. If the calculated
                  settlement indicates BST owes Client, the electronic funds
                  transfer or settlement check will be processed so as to be
                  received by Client by the last workday of the month following
                  the report month. In the event Client remittance is not paid
                  in full by the date contained in the paragraph herein,
                  interest charges shall apply as set forth in Section 53
                  relative to charges owed to Client by BST. If the calculated
                  settlement indicates Client owes BST, Client will remit the
                  amount due to be received by BST within thirty days following
                  report month close. If payment is not received within thirty
                  days, interest charges will apply as described in Section 53
                  of this Agreement. Upon written notification by BST to Client,
                  BST may, in its sole discretion, suspend billing services if
                  outstanding charges are not paid in full on time as described
                  herein.

                  If agreed to by the Parties, electronic funds transfer may be
                  used to accomplish the settlement.

         C.       The BST Billing and Collections Services billing will be
                  accomplished via the Cost Based Billing (CBB) system. This is
                  the standard affiliate inter-company settlements process. The
                  BST charges for billing services rendered to the Client will
                  be billed by the BST Cost Based Billing group (CBB) on behalf
                  of BST. The charges for services rendered will be billed the
                  month following the month the charges are incurred. The
                  billing services provided by BST will be billed at the rates
                  set forth in Attachment 1. The charges calculated by the CBB
                  group for services provided by BST to the Client will be
                  processed through the BellSouth Global Inter-Company
                  Settlement (GIS) system.

                  BST will generate billing by the thirtieth (30th) day of the
                  month following the month charges are incurred, and as set
                  forth in Attachment 1. Payment is due within thirty (30) days
                  of the posted date of the bill and should be remitted to the
                  BST address shown in Attachment 5. If payment is not received
                  within thirty days, interest charges will apply as described
                  in Section 53 of this Agreement

         D.       Settlement Reserve

                  BST will not require and does not maintain any "Settlement
                  Reserve" against which future uncollectibles or adjustments
                  would be offset. Following termination of this Agreement,
                  Client shall continue to receive recoursed uncollectibles and
                  adjustments for revenues submitted for billing under this
                  Agreement.

23.      SETTLEMENTS OF CLAIMS

         In the event that Client disputes the settlement statement or Billing
         and Collections Services bill, the Client must submit to BST a
         documented claim in writing for the disputed amount. The Client will
         submit any dispute promptly but no later than six (6) months from
         report month so that the information relevant for the investigation of
         the dispute may be reviewed

                                                                              17

--------------------------------------------------------------------------------

         by both Parties. Both Parties will use best efforts to resolve the
         dispute. The responsibilities are as follows:

         A.       DISPUTE DATE AND DOCUMENTATION

                  The dispute date is the date on which BST receives the
                  Client's documented claim in writing. Such documentation must
                  include, at a minimum, but is not limited to:

                  l).      The nature of the dispute, including the basis for
                           the Client's belief that the settlement or Billing
                           and Collections Services bill is incorrect

                  2).      The amount of money in dispute identified by
                           category; e.g., Billed Revenue, Adjustments

                  3).      The report month and the RAO(s) for the settlement
                           statement

                  4).      Any applicable transmission dates or sequence pack
                           numbers

                  BST may request the Client to provide any additional
                  information if needed. Any request for additional information
                  will not affect the established dispute date if the Client
                  meets the written documentation requirements stated herein.

         B.       RESOLUTION OF DISPUTE

                  If after investigation of the dispute, the statement in
                  question is found by BST to be correct and the Client concurs
                  with BST's findings, both Parties will consider the dispute
                  settled.

                  If the statement is found to be incorrect by both
                  Parties, the dispute will be settled as follows:

                  1)       The amount determined to be the settlement amount for
                           the claim will be documented in BST's findings as the
                           "settlement claim amount".

                  2)       If a credit is due the Client, the settlement claim
                           amount due less any disputed amounts associated with
                           the claim withheld by the Client will be credited to
                           the Client on a subsequent settlement. Interest
                           charges will apply as described in Section 53 of this
                           Agreement.

                  3)       In the event that payment is due BST, the same
                           provisions as set forth in this section will apply as
                           with payments due the Client. Interest charges will
                           apply as described in Section 53 of this Agreement.

         C.       ESCALATION OF SETTLEMENTS DISPUTE

                  In the event that a settlements dispute is not resolved in a
                  timeframe acceptable to either the Client or BST the dispute
                  should first be escalated to the Contract Administrators and
                  then Cingular's Controller and BST's Accounts Receivable
                  Management-Assistant Vice President. If not resolved by the
                  above, the dispute shall be escalated to the Cingular
                  President and to the BST Vice President-Finance, Chief
                  Financial Officer-Domestic Operations.

24.      TAXES

         All taxes including but not limited to Federal, State, or local sales,
         use, excise, gross receipts or other taxes or tax-like fees imposed on
         or with respect to Client's services, excluding however, advalorem
         property taxes, state and local privilege and license taxes based on
         gross revenue, taxes measured by net income, and any taxes or amounts
         in lieu of the foregoing excluded items, are hereinafter collectively
         referred to as "Taxes", unless otherwise specifically named.

         BST shall print and bill in the format required and the time frame
         specified, applicable Taxes, as provided by Client to BST, to End User
         Customers, as mutually agreed upon. Client shall calculate and provide
         to BST all applicable taxes related to Client's services.

         BST shall collect taxes computed by Client from End User Customers on
         Client's behalf and remit such Taxes to Client through the settlement
         process.

         BST shall not remit Taxes to Client when it is not able to do so as a
         result of legal restrictions; however, Client reserves the right to
         challenge such determination.

         BST shall not be entitled to retain or receive any statutory fee or
         share of Taxes that the person collecting or remitting such Taxes is
         entitled under applicable law.

         BST is providing this service for a specific fee. BST shall not report
         related Client's revenues as its own receipts for gross receipts tax
         purposes or any other tax purposes.

         BST shall not be responsible for calculating and billing any foreign
         state taxes associated with a jurisdiction where the call originates in
         a state other than the billing state, unless the foreign state tax
         information is calculated by Client and provided to BST for printing on
         End User Customers bill.

         Should any Federal, State or local jurisdiction determine that sales,
         use, gross receipts or any other taxes (including interest, penalties,
         and surcharges thereon) are due by BST as a result of BST's provision
         of this service and such taxes have not already been billed by BST and
         paid by Client, BST shall advise Client and Client shall be liable for
         any such tax, interest, penalties and surcharges, and Client shall
         immediately reimburse BST the amount of such tax, interest, penalties
         and surcharge paid by BST. If Client disagrees with BST's determination
         that any taxes are due by BST as a result of BST's provision of this
         service, Client shall, at its option and expense (including immediate
         payment of any such assessment), have the right to seek a ruling as to
         the inapplicability of any such tax or to protest any assessment and
         participate in any legal challenge to such assessment, but shall be
         liable for any tax, penalty, surcharge and interest ultimately
         determined to be due.

         All communications with taxing authorities regarding Taxes applicable
         to Client shall be the responsibility of the Client.

         Client understands and agrees that BST is merely providing Services
         with respect to the billing and collection of Taxes hereunder.

         Client shall file all tax returns and pay or remit all such Taxes to
         the imposing authority.

TAX INDEMNITY AND RECOURSE

BST agrees to pay and hold Client harmless from and defend (at BST's expense)
Client from and against any liability or loss resulting from tax, penalties,
interest, additions to Tax, or other charges or payable expenses (including
reasonable attorney's fees) incurred by Client as a result of:

         l).      The failure of BST to bill End User Customer Taxes as required
                  by Client through the Invoice Billing Service; or

         2).      BST's recalculation or alteration of Taxes sent to BST through
                  the Invoice Billing Service. This sub-paragraph does not apply
                  to recourse adjustments initiated by BST or to adjustments
                  received by other than the mechanized Invoice Processing feed.

Such indemnity shall be provided to Client on an after Tax basis.

Client shall indemnify and hold harmless, and defend (at Client's expense) BST
from and against any liability or loss resulting from any Taxes, penalties,
interest, additions to Tax, or other charges or payable expenses (including
reasonable attorney's fees) incurred by BST as a result of:

         1).      Client's failure to pay any Tax or file any return or other
                  information as required by law or the Agreement; or,

         2).      BST complying with the Agreement or with any determination or
                  direction by or advice of Client provided in writing by Client
                  or BST correctly using information provided in writing by
                  Client in performing any Tax-related service hereunder; or

         3).      BST acting or failing to take any action with respect to any
                  Tax which is subject of the Agreement.

Notwithstanding, the above, such indemnity is conditioned upon BST providing
Client or Client providing BST with notice (which notice shall be given allowing
the Party time to file a response, but in no event more than 10 business days of
receipt of assessment) of any additional Tax, penalties, or interest due with
respect to this Agreement. BST shall receive a copy of all filings in any such
proceeding, protest or legal challenge, all rulings issued in connection
therewith and all correspondence between Client and the taxing authority.

If Client disagrees that any Taxes are payable by BST, disagrees with an
assessment of any additional Taxes, penalties, interest, additions to Tax
surcharges, or other charges or payable expenses due by BST as a result of BST's
billing to Client for services under this Agreement, Client shall, at its option
and expense (including, if required by a taxing authority, payment of such Tax,
penalties and interest prior to final resolution of the issue have the right to
seek administrative relief, a ruling, judicial review (in a manner deemed
appropriate by Client), as to the applicability of any Tax, penalty or interest,
or to protest any assessment and direct and legal challenge filed with the
Internal Revenue Service or in a court of Law such assessment, and shall be
liable hereunder for any such amount ultimately determined to be due.

         enhancements and/or modifications to its service. There are cases when
         additional work is required due to Client requests such as new bill
         phrases, new product billing, re-sends of data, etc. All such Client
         requests will be handled as additional work requests unless the work is
         a result of changes initiated by BST.

         The Client should provide a written request completely detailing the
         service modifications needed. If more information is needed by BST, BST
         will provide Client with a list of questions and issues. Once complete
         specifications are provided by Client, BST will provide a response with
         the time and cost estimate.

         The Client will have up to forty (40) working days to provide written
         authorization concurring with BST's time and cost estimate and
         authorizing BST to begin the work. The timeframe for implementation
         will be dependent upon receipt of written authorization to proceed. The
         cost for performing the enhancement will be billed to the Client on its
         billing and collections statement for portions of the work as they are
         completed by BST. This billing will typically be one month in arrears.
         (Ex. billing for work undertaken for a project in January will be
         billed on the February bill.) If the Client cancels a request, it will
         be billed for the work completed to date of cancellation.

         Client modifications requested may also require additional recurring
         processing expense for BST. In those cases, new recurring rates may be
         established or the rates for existing rate elements may be increased.

         The Client will be charged at rates set forth in Attachment 1 for the
         non-recurring development work required for BST to develop and
         implement the request.

         TESTING

         New procedures, which require mutual testing, must be coordinated by
         both Parties and a mutually acceptable test schedule timeline and
         frequency established. Since future enhancements are determined on an
         ICB, testing must be included in this process.

26.      LIMITATION OF LIABILITY

         The Client agrees that BST assumes no liability for any action or claim
         arising out of BST's billing or determination to refuse to bill any of
         Client's charges. The liability of BST for damages arising out of
         mistakes, omissions, interruptions, delays, errors or defects in
         rendering services hereunder and not caused by the negligence of the
         Client shall in no event exceed an amount equivalent to the
         proportionate charges to the Client for the service which was affected
         by such mistakes, omissions, interruptions, delays, errors, or defects.
         Neither Party shall be liable for lost profits, lost savings or other
         such damages, including without limitation special, exemplary,
         indirect, incidental or consequential damages arising out of or in
         connection with this Agreement or in connection with either Party's
         failure to perform its obligations hereunder.

27.      INDEMNITY

         Both parties represent and warrant that any data files which are to be
         processed by either company and any bill or notice formats comply with
         the criteria and requirements set forth in this Agreement, any
         governmental laws, codes and regulations, and any attachments,
         exhibits, addendum's, amendments and good business practices. Each
         Party shall defend at its own expense and indemnify and hold the other
         Party harmless from all claims, lawsuits, actions, complaints, damages,
         demands, liabilities, penalties, interest and expense, (including
         reasonable attorney's fees) arising out of either company's breach of
         the foregoing representation and warranties.

         HEREIN RESPECTING EQUIPMENT FURNISHED OR SERVICES PERFORMED UNDER THE
         AGREEMENT.

29.      CONFIDENTIALITY AND PUBLICITY

         A.       All business-sensitive and competitive information disclosed
                  by Client or BST during the negotiation of this Agreement as
                  well as information generated during the performance of the
                  Services covered by this Agreement are considered proprietary
                  and confidential to the disclosing Party and shall not be
                  disclosed to a third party. Also, neither Party shall use
                  information except to perform duties pursuant to this
                  Agreement. Each Party shall use the same standard to protect
                  such information as it uses to protect its own similar
                  confidential and proprietary information unless such
                  information was previously known to the other Party free of
                  any obligation to keep it confidential, or has been or is
                  subsequently made public by either Party or a third party.

         B.       Unless otherwise required by applicable law or regulatory
                  agency, each Party agrees that it shall not, without the prior
                  written consent of the other Party, make any news release,

                  confidential information which may be considered proprietary
                  by either or both Parties, and agree to limit distribution of
                  this Agreement to those individuals in their respective

                  requirements of a court, regulatory body or government agency
                  having jurisdiction over either Party provided that such Party
                  will seek commercial confidential status for the Agreement to

30.      TRADEMARKS, TRADE NAMES AND SERVICE MARKS

         BST agrees to submit to Client all advertising, sales promotions, press
         releases, and other publicity matters relating to this Agreement or
         mentioning or implying the trade names, logos, trademarks or service
         marks (collectively called "Marks") of Client or language from which
         the connection of said Marks therewith may be inferred or implied, or
         mentioning or implying the names of any personnel of Client. BST
         further agrees not to publish or use such advertising, sales
         promotions, press releases, or publicity matters without Client's prior
         written consent.

         A.       LICENSE FOR MARKS.

                  The Parties retain exclusive ownership of their trademarks,
                  service marks, logos and trade names ("MARKS"). Client hereby
                  grants to BST a personal, nonexclusive, limited right,
                  assignable only as provided within this Agreement, to
                  reproduce Client's Marks for use as defined herein and as
                  necessary for fulfilling any obligations or exercising any
                  rights under this Agreement. Client agrees that BST may affix
                  such Client Marks to materials provided for hereunder. BST
                  shall strictly adhere to all graphic standards and marking
                  requirements required by Client as may be revised or
                  supplemented from time to time. In the case of BellSouth's
                  Marks, the parties acknowledge that any license to use
                  applicable BellSouth marks must be obtained from BellSouth's
                  corporate affiliate, BellSouth Intellectual Property Marketing
                  Corporation.

                           1).      Client and its Affiliated Companies' trade

                                    are the property of Client. In response to

                                    trademarks, trade names, logos, symbols,

                                    furnished hereunder, Client hereby grants to
                                    BST a personal, nonexclusive, limited right,
                                    assignable only as provided within this
                                    Agreement, to reproduce and affix Client's
                                    Marks for use as defined herein and as
                                    necessary for fulfilling any obligations or
                                    exercising any rights under this Agreement.
                                    BST shall strictly adhere to all graphic
                                    standards and marking requirements required
                                    by Client as may be revised or supplemented
                                    from time to time.

                                           VERSION FINAL. SEPTEMBER 3, 2003

                                                                              23

                           2).      BST's and its Affiliated Companies' trade
                                    names, logos, trademarks and service marks
                                    are the property of BellSouth Intellectual
                                    Property Corporation ("BIPCO"). In response

                                    Agreement attached as Appendix A. Client
                                    shall not affix, use, or otherwise display
                                    such Marks on the Material or use the Marks
                                    in any manner inconsistent with the terms of
                                    the Trademark License Agreement. BIPCO shall
                                    retain all right, title, and interest in any
                                    and all Marks, packaging design and finished
                                    artwork provided to BST.

                           3).      Neither party will use the name, logo,
                                    trademarks or service marks of the other
                                    Party without obtaining advance written
                                    approval from the other party regarding such
                                    use, including use in a domain name. The
                                    request for approval will include the
                                    specific copy for which use is proposed.

         B.       OWNERSHIP OF WORK PRODUCT

                  "Work Product" means all software (object and source code),
                  technical information, inventions, discoveries, improvements,
                  methods, techniques, training material, processes,
                  specifications, works of authorship, documentation, data
                  format and other information conceived, developed or first
                  reduced to practice by a Party, its employees, consultants or
                  representatives, under or resulting from this Agreement.
                  Unless otherwise agreed to by authorized representatives of
                  the Parties, in writing, in advance of the creation of the
                  Work Product, the Party developing such information shall own
                  all right, title, and interest, including copyright, in and to
                  the Work Product.

         C.       CONFIDENTIALITY

                  It may be necessary for BST to provide Client with certain
                  proprietary and confidential information, specifically
                  software containing data format information, solely for the
                  purpose(s) of data exchange. Client may share data format
                  information with its partner companies provided both Client
                  and partner companies agree that each shall protect the
                  information from any use, distribution or disclosure except as
                  permitted hereunder. Client and its partner companies will use
                  the same standard of care to protect the information as its
                  uses to protect its own similar confidential and proprietary
                  information, but not less than a reasonable standard of care.
                  Client may provide data format information only to its partner
                  companies who: (i) have a substantive need to know such
                  information in connection with this Agreement; (ii) have been
                  advised of the confidential and proprietary nature of such
                  information; and (iii) have personally agreed in writing to
                  protect from unauthorized disclosure all confidential and
                  proprietary information, of whatever source, to which they
                  have access in the course of their employment.

31.      SOFTWARE

         The Parties or their contractors or agents may develop specifications,
         drawings, documentation, concepts, methods, techniques, processes,
         adaptations and ideas including, but not limited to software
         (hereinafter "Software") for the purpose of rendering Services under
         this Agreement. Unless otherwise agreed by authorized representatives
         of the Parties, in writing, in advance of the creation of the Software,
         the Party developing such information shall own all right, title, and
         interest, including copyright, in and to the Software.

         The Client may share data format information for the purpose of data
         exchange with its partner companies provided those companies use the
         formats internally only.

32.      ASSIGNMENT

         Neither Party shall assign any right, obligation or duty, in whole or
         in part, or any other interest hereunder, without the written consent
         of the other Party, which consent shall not be unreasonably withheld.
         Provided, however, that either Party, may, without the other Party's
         consent, assign this Agreement to any of its Affiliated Companies or
         may subcontract the performance of any of its obligations hereunder to
         such an affiliate company provided that such affiliate is financially
         and technologically able to perform the Assignor's duties under this
         Agreement. If assigned to an Affiliated Company by BST, this Agreement,
         and rates contained herein, may be modified by mutual agreement by the
         Contract Administrators for BST and the Client. If new terms and
         conditions cannot be mutually agreed upon, either Party may terminate
         this agreement without any further liability hereunder other than for
         services previously rendered.

         Client understands and agrees that at its sole discretion, BST may
         delegate any duty in this Agreement to an affiliate for such affiliate
         to perform on behalf of BST.

33.      AUTHORIZATION TO CONDUCT BUSINESS

         A.       Client and BST shall comply with the provisions of all
                  applicable federal, state, county and local, laws ordinances,
                  orders, tariffs, regulations and codes. The Parties shall
                  indemnify each other for, and defend each other against, any
                  loss or damage sustained because of the indemnifying Party's
                  noncompliance.

         B.       The Parties shall obtain and keep current all federal, state,
                  and local licenses or approvals that may be required for the
                  performance of this agreement. Upon request, copies of all
                  required licenses and approvals shall be furnished to each
                  other. If either Party does not comply with such a request

                  Florida, Georgia, North Carolina and South Carolina. It also
                  includes limited areas in adjacent states to the extent that
                  BST has existing customers to whom it sends bills and any
                  other areas where Client may operate in the future within the
                  BST operating territory.

         C.       The above addresses may be changed by written notice given by
                  such Party to the other Party pursuant to this section.

35.      NO THIRD-PARTY BENEFICIARIES

         This Agreement is not intended to create any third-party beneficiary
         rights and shall not provide any person not a party to this Agreement
         with any remedy, claim, liability, reimbursement, cause of action or
         other right.

36.      TERMINATION UPON EVENT OF DEFAULT BY A PARTY

         A.       Upon the occurrence of an event of default (as hereinafter
                  defined) by a Party, and so long as such event of default
                  shall be continuing, the aggrieved Party may elect to give
                  notice to the defaulting Party that the Agreement is
                  terminated and, if the aggrieved Party shall elect, proceed by
                  appropriate court action, either at law or in equity, to
                  recover damages for the breach thereof. The occurrence of any
                  of the following shall constitute an event of default:

                  1).      Any Party shall fail to pay any amounts due under
                           this Agreement and such failure to pay shall continue
                           for more than thirty (30) business days after written
                           notice from the aggrieved Party.

                  2).      Any representation or warranty made by a Party in
                           this Agreement or in any report, certificate,
                           financial statement or other statement furnished
                           pursuant to the provisions of this Agreement or
                           otherwise, shall prove to have been false or
                           misleading in any material respect as of the date on
                           which the same was made.

                  3).      Any Party shall fail in any material respect to duly
                           observe or perform any covenant, condition or
                           agreement made by it in this Agreement and shall
                           continue to fail to do so for a period of thirty (30)
                           business days after receipt of written notice
                           thereof.

                  A "business day" or "Working day" shall mean a calendar day,
                  excluding Saturdays, Sundays, and all holidays celebrated by
                  BST. On an annual basis, prior to the beginning of each
                  calendar year, BST shall provide Client a list of said
                  holidays.

         B.       The foregoing does not represent the sole and exclusive remedy
                  of a Party upon the occurrence of an event of default by
                  another Party.

37.      AGREEMENT TERMINATION

         Either Party may terminate this Agreement at its sole discretion
         without cause by providing the other Party with a ninety (90) day
         written notice.

         Upon discontinuance of services, all charges incurred by the Client
         will be due to BST. Any settlements owed to the Client will be paid by
         BST.

                                                                              27

38.      OBLIGATIONS SURVIVE TERMINATION

         The Parties agree that the termination of this Agreement pursuant to
         any provision or section hereof, or for any other reason, shall not
         affect or terminate any obligation or liability incurred or assumed by
         either Party prior to the effective date of termination of this
         Agreement, and the provisions of this Agreement shall survive its
         termination with respect to conclusion of any unresolved matters
         relating to the Services performed prior to termination. Upon
         termination of this Agreement by either Party for default or
         convenience, each Party will be responsible for paying any and all
         outstanding amounts due to the other Party. With respect to Client,
         these amounts, which must be paid to BST, may include, but are not
         limited to, unbillables, uncollectibles, unguideables, and Billing and
         Collections Services charges which relate to services provided under
         this Agreement, and may include amounts that occur subsequent to the
         date of termination.

39.      SEVERABILITY OF PROVISIONS

         Except as expressly provided in this Agreement, if any part of this
         Agreement is held or construed to be invalid or unenforceable, such
         provision shall be severed from this Agreement and all other terms and
         conditions of this Agreement shall remain in full force and effect to
         the extent permissible or appropriate in furtherance of the intent of
         this Agreement as if such severed provision had never been a part
         hereof.

40.      UNLAWFUL USE

         The service provided under this Agreement will not be used by the
         Client for any unlawful purpose. If the Client uses the service for any
         unlawful purpose, the Client will indemnify, defend and hold the
         company harmless against any and all damages and expenses, arising in
         any manner, due to the Client's use of the service in any unlawful way.
         The Client's use of this service for an unlawful purpose will be
         grounds for BST to immediately terminate this Agreement without notice.

41.      TERM OF AGREEMENT

         This Agreement shall continue in effect for the term provided in this
         Agreement. After the primary term expires, unless otherwise terminated

         increments until terminated. Upon termination by either Party certain
         charges as specified in this Agreement or attachments and amendments
         may be applicable. This Agreement will continue to apply to invoices
         received prior to termination throughout the remainder of the billing
         month.

48.      LATE PAYMENT CHARGES ON END-USER ACCOUNTS

         Where authorized by appropriate regulatory agencies, BST will apply
         late payment charges automatically to End-User bills based on balance
         due. A late payment charge is applied when any undisputed portion of a
         previous month's bill has not been paid in full prior to the subsequent
         bill date. Any payment of these charges by End-User, waiver or
         adjustment of late payment charges is considered BST revenue and does
         not involve Client settlements, even though the basis for the late
         payment charges could include Client invoice revenues. The Client is
         not permitted to bill late payment charges assessed by the Client on
         combined bills.

49.      INTEREST ON END-USER ACCOUNTS

         Interest calculated on BST charges or paid by BST to End-Users will not
         use Client invoice revenues in the basis for calculation. Client
         End-Users will not receive interest from BST for any Client services.
         Interest paid to End-Users by the Client must be included in the Client
         invoice, identified to the End-User, and be represented as a "net" of
         Client charges when provided to BST on the invoice.

50.      DEPOSITS ON END-USER ACCOUNTS

         If a deposit is required to establish Client service to an End-User,
         the deposit for Client services must be determined and secured by the
         Client. Charges for or refunds for deposits may be included in the
         invoice sent to BST for inclusion in the End-User bill. The Client will
         be responsible for holding the End-User deposits.

51.      NPA/NXXFile

         BST will provide to the Client a mechanized file of BST NPA/NXX/RAO
         information for Client use in mapping Client bill cycles to BST bill
         cycles, if Client desires to do so. This file will be provided each
         bill cycle of BST (there are 20 bill cycles per month) and will contain
         the complete set of data each time. If BST revises the specifications
         for the NPA/NXX/RAO data file, BST will notify Client at least ninety
         (90) days before the changes are implemented.

52.      NPA SPLIT PROCEDURES

         The Client understands that it has multiple options for NPA split
         notifications. BST recommends that a combination of options be employed
         by the Client. The Client will be responsible for updating it's NPA/NXX
         splits.ide NXX information.)

53.      INTEREST ON SETTLEMENTS, CLAIMS, AND LATE PAYMENT.

         A.       The interest paid on late payment and claim payment amounts is
                  .67% per month (.0222% per day simple interest) or 8%
                  annually. The resulting amount will be rounded to the nearest
                  penny; i.e., to two decimal places.

         B.       Calculation of Interest Payments

                  1).      Treatment and Collection Services Bills

                           For Treatment and Collection Services bills, the
                           interest rate stated above will be applied as a late
                           payment factor to the portion of the Client payment
                           not received by BST on the payment due date. It is
                           calculated for the number of days from the payment
                           due date to, and including, the date BST receives the
                           full payment from the Client.

                  2).      Treatment and Collection Claim Payments

                           For Treatment and Collection Services bill claim
                           payments, the interest rate stated above will be
                           applied to the amount owed. Interest will accumulate
                           beginning either on the date the written documented
                           claim is received by BST or from the bill payment due
                           date, whichever occurs later.

                  3).      Settlements Payments

                           For Settlements payments, the interest rate stated
                           above will be applied as a late payment factor to the
                           portion of the balance due not received by the Party
                           owed by the Settlement due date. It is calculated for
                           the number of days from the payment due date to, and
                           including the date the Party owed receives full
                           payment from the indebted Party.

                  4).      Settlements Claim Payments

                           For Settlements claim payments, the interest rate
                           stated above will be applied to the amount owed.
                           Interest will accumulate beginning either on the date
                           the written documented claim of the monies in
                           question is received by BST or from the settlement
                           due date, whichever occurs later.

                  5).      Audit Claim Payments

                           For Audit claim payments, the interest rate stated
                           above will be applied as follows:

                           a.       Application of the interest payment to the
                                    claim amount will start on the date the
                                    claim is received under the conditions that
                                    all supporting documentation is attached to
                                    the claim and that both Parties mutually
                                    agree that the documentation is accurate and
                                    sufficient. When supporting documentation
                                    has to be gathered by either or both
                                    Parties, application of the interest payment
                                    will begin the day both Parties mutually
                                    agree that the supporting documentation is
                                    complete and sufficient and on the claim

                              CONFLICTS OF INTEREST

BST does business with thousands of contractors and suppliers. It is a
fundamental policy of BST that such dealings shall be conducted on a fair and
impartial basis, free from improper influences, so that all participating
contractors and suppliers may be considered on the basis of the quality and cost
of their product or service.

We are also committed to doing business with contractors and suppliers in an
atmosphere that is in keeping with the highest standards of business ethics.
Although we recognize that the exchange of gifts and entertainment is customary
in some businesses, we believe this practice often raises embarrassing questions
about the motives of both the giver and receiver. Therefore, this company has
for some time followed a policy that its employees shall not accept from
customers, suppliers of property, goods, or services, or from any other persons,
any gifts, benefits, or unusual hospitality that may in any way tend to
influence them, or have the appearance of influencing them, in the performance
of their jobs.

Employees of BST who are authorized to make purchases or negotiate contract are
aware of this policy.

We believe that firm adherence to this policy will help establish better
business relationships between BST and its contractors and suppliers. We solicit
your cooperation in achieving that objective.

         Final Bill.

         depending on the context. When discussing End-Users and post-billing

         End-User has notified the Client of a claim and the Client, after
         investigation, sustains the charges and the End-User continues to
         refuse to pay and contacts BST for assistance. When discussing
         Treatment and Collections Service charges, Settlement, and audit

         Client and BST as to the amount due or owed.

                           and tariffs. This Agreement and its Exhibits attached
                           hereto and incorporated herein, complement such

                           not in conflict with the provisions of such tariffs,
                           are to be construed to the extent possible in harmony

                           Agreement and SBC Telco may elect to terminate the
                           Agreement pursuant to Section 9, Termination of
                           Services.

                  5.3.5    The Customer will use commercially reasonable efforts
                           to submit billings on a regular and consistent basis
                           of at least once every week and if the Customer fails
                           to submit billings within three (3) months from the
                           effective date of this Agreement, Customer will be
                           deemed to have breached this Agreement and SBC Telco
                           may elect to terminate it immediately.

                  5.3.6    The Customer shall notify SBC Telco of any billing
                           problems that impact the requirement to submit
                           billings on a regular and consistent basis after
                           commencement of services. If the Customer fails to
                           provide such notice and fails to submit billings on a
                           regular and consistent basis of at least once every
                           week after commencement of services, Customer will be
                           deemed to have breached this Agreement and SBC Telco
                           may elect to terminate pursuant to Section 9,
                           Termination of Services. SBC Telco at its sole option
                           may withhold payment of any monies due the Customer,
                           until such time that the Customer submits billings at
                           least once a week and demonstrates that such billings
                           are true and correct.

                  5.3.7    In accepting information to be billed on behalf of
                           Customer, SBC Telco will confirm both the receipt of
                           the billing information and the total amount of the
                           billing information received. SBC Telco will provide
                           confirmation in a format determined by the SBC Telco.

                           Customer' messages subject to SBC Telco's ability to

                           a specific SBC Telco approves in writing in advance
                           of such billing. Roaming charges must be submitted

                           this provision will materially affect the essence of
                           this Agreement and will constitute a substantial
                           breach of its terms. SBC Telco reserves the right to
                           return to the Customer any such messages prior to
                           billing the End User. In the event that SBC Telco

                           rated messages to be filled by SBC Telco. The
                           Customer will deliver its messages to be billed by
                           SBC Telco to a location specified by SBC Telco. The
                           Customer will uniquely identify its deniable and

                           re-supply to SBC Telco if necessary, for a minimum of

                           to SBC Telco. This will allow SBC Telco to
                           reconstruct lost records. If the Customer fails to
                           maintain a back-up file of messages to SBC Telco
                           throughout the prescribed timeframe, SBC Telco will

                           will be treated as unbillable messages and returned
                           to the Customer without investigation.

                  5.4.6.   SBC Telco will return to the Customer messages that
                           are to be billed to an End User that has elected a
                           local service provider other than SBC Telco.

                  5.4.7.   In the event the Customer requests data that has
                           previously been successfully provided by SBC Telco to
                           Customer, the data, if available, will be re-provided
                           to the Customer through the Time and Cost procedure.

                  5.4.8.   Customer message detail determined to be lost as a
                           result of the Master File Maintenance processing will
                           be recovered, if possible, by SBC Telco. In the event
                           the data cannot be recovered by SBC Telco and the
                           Customer's obligation to re-supply the data has
                           expired, SBC Telco will in all instances assume that
                           the data lost is attributable to direct dialed long
                           distance service and will estimate the messages and
                           associated revenues as follows:

                           a)       Unless otherwise agreed to by the Customer
                                    and SBC Telco, Cingular's average
                                    direct-dialed per minute rate billed its End
                                    Users will be used to calculate the revenues
                                    associated with the lost records. A
                                    reduction to the calculated revenue loss,
                                    for projected billing and collection
                                    charges, adjustments and uncollectibles,
                                    will be made based on the per message charge
                                    and bill rendering charge. The number of
                                    bill rendering charges will be based on the
                                    Customer's average number of messages per
                                    bill rendered. This estimate will be used to
                                    adjust the Amount Due the Customer as
                                    specified Exhibit B.

         5.5      MESSAGE INVESTIGATION CENTER

                  5.5.1    SBC Telco will provide Message Investigation Center
                           (MIC) services to the Customer for the investigation
                           of the Customer's messages that are unbillable under
                           certain error codes to an End User (pre-billing
                           errors). In these instances, SBC Telco will utilize
                           its methods and procedures to determine the dollar
                           level at which investigation of messages will occur
                           and/or for the return of messages to the Customer.
                           SBC Telco will not be liable to the Customer for
                           revenue associated with messages that are unbillable.

                  5.5.2    SBC Telco will recover customer messages determined
                           to be lost, as a result of MIC services at no charge.
                           In the event SBC Telco cannot recover the messages,
                           procedures defined in Section 5.4 will be utilized
                           to estimate an adjustment to the Customer's Amount
                           Due.

                           billed by SBC Telcos.

                  5.6.2    Partial Payments on accounts may be applied by SBC
                           Telcos first to amounts owed for charges for which
                           telephone service may be disconnected for nonpayment
                           and SBC Telcos' own products and services.

         5.7      TREATMENT AND COLLECTION SERVICE

                  5.7.1    Treatment and Collection service is the method of
                           securing payment of past due charges for Customer's
                           products and services. SBC Telcos provide treatment
                           and collection services in an attempt to control or
                           collect appropriate outstanding balance due amounts.
                           Treatment and Collection services include, but are
                           not limited to, preparation and mailing of account
                           status notices to End Users, imposition of late
                           payment fees where authorized and permitted by law,
                           and the initiation of final collection efforts. SBC
                           Telcos shall provide treatment and collection
                           services to Customer in connection with End User
                           accounts which SBC Telcos provides payment and
                           remittance processing.

                  5.7.2    The SBC Telco will utilize the same steps and
                           procedures in collecting the Customer's accounts as
                           it does on its own behalf. The SBC Telco will
                           determine and collect deposits from End Users for
                           which the SBC Telco provides Billing and Collection
                           Services according to regulatory requirements and the
                           SBC Telco deposit policy. The SBC Telco deposit
                           policy is nondiscriminatory with regard to the entity
                           on behalf of which the service is billed.

                  5.7.3    Where appropriate regulatory authority permits
                           denial of services and/or by Customer's contract with
                           the End User, Customer authorizes SBC Telco to deny
                           service and disconnect End Users for non-payment in
                           accordance with such procedures.

                  5.7.4    This Agreement does not obligate SBC Telco to
                           terminate End User services for non-payment. Upon
                           completion of SBC Telco collection procedures for
                           non-payment of any charges appearing on the End User
                           Bill, SBC Telco may adjust, in its sole discretion,
                           such charges with recourse to Customer. In addition,
                           the Parties acknowledge that changes in applicable
                           laws or regulations may prevent SBC Telco from
                           terminating or threatening to terminate End User
                           service for non-payment of any Customer charges, and
                           that such actions may require changes in SBC Telco
                           procedures.

                           there are no third party beneficiaries to this. The
                           Customer and SBC Telco further agree that, under the
                           terms of this agreement, the purchase of the
                           Customer's accounts receivables is a revenue neutral
                           process to SBC Telco, and that the procedures defined
                           in Exhibit B, which are utilized for the purchase of
                           Customer's accounts receivables, result in a revenue
                           neutral process for SBC Telco. The parties agree that
                           Customer is obligated to forward only true, correct
                           and owing charges to the SBC Telco for billing and
                           collection, that the SBC Telco will not knowingly
                           bill disputed or unauthorized charges, that it is a
                           breach of contract for Customer to forward disputed
                           and/or unauthorized charges to the SBC Telco for
                           billing and collection and that the SBC Telco may
                           terminate billing and collection for Customer, in

                           as a result of end user complaints lodged with the
                           SBC Telco, FCC, any state PUC, commission, or
                           regulatory agency; or any suit filed or investigation

                           other local exchange carrier. The parties further
                           agree the SBC Telco does not financially benefit from
                           billing Customer's disputed and unauthorized charges
                           and, instead, incurs additional, significant expense
                           and loss of end-user good will.

                                    Customer, SBC Telco will use the same Tax
                                    procedures as it applies to its own similar
                                    services. SBC Telco makes no warranties or
                                    representations as to whether its Tax
                                    procedures accurately reflect the
                                    requirements of the applicable Tax laws. If
                                    Customer elects to have SBC Telco apply its
                                    Tax procedures, Customer shall have the sole
                                    responsibility for verifying the correct
                                    application of Tax laws to Customer's
                                    services. Customer may, upon written
                                    request, review the SBC Telco's Tax
                                    procedures applicable to the billing of
                                    Customer's services. Customer shall be
                                    responsible for advising SBC Telco in
                                    writing of any changes in the Tax laws
                                    affecting the taxability of Customer's
                                    services.

                           5.10.1.4 Customer may request in writing that SBC
                                    Telco apply modified Tax procedures to the
                                    billing of Customer's services if either of
                                    the following applies:

                                    a)       The modifications reflect changes
                                             in the Tax laws applicable to
                                             Customer's services to be billed
                                             under this Agreement; or

                                    b)       The modifications are pursuant to
                                             an investigation of what Customer
                                             believes are errors in the SBC
                                             Telco tax procedures and, if SBC
                                             Telco deems appropriate, the
                                             modifications correct the alleged
                                             error.

                           5.10.1.5 Provided reasonable advance notice is given
                                    and no undue burden is imposed upon SBC
                                    Telco in implementing such changes, SBC
                                    Telco agrees to use reasonable efforts to
                                    implement such modified Tax procedures on a
                                    timely basis based upon the effective date
                                    of service or the statutory effective date
                                    of a Tax law change. SBC Telco shall charge
                                    Customer for such implementation services at
                                    the Time and Cost ("T&C") rates specified in
                                    Exhibit A hereto. Whenever the SBC Telco
                                    estimates that the time required for it to
                                    implement a change in the Tax law would
                                    preclude its implementation by the statutory
                                    effective date, the Parties will together
                                    apply to the taxing authority for an
                                    appropriate extension of the effective date
                                    of a change.

                           5.10.1.6 Both parties acknowledge that SBC Telco is
                                    merely acting as Customer's agent with
                                    respect to the calculation, billing and
                                    collection of Taxes under this Agreement.
                                    SBC Telco shall not be entitled to retain or
                                    receive from Customer any statutory fee or
                                    share of Taxes to which the person
                                    collecting such Taxes is entitled under
                                    applicable law.

                  5.11.1   Rates and charges applicable to the Billing and
                           Collection Services covered by this Agreement are

                                                                   EXHIBIT 10.62

5.11.3   For the purposes of billing the Customer for SBC Telco services
         provided under this Agreement, the determination of rates and charges
         and procedures for intrastate messages originating and terminating in
         one state and billed to an End-User in another state (billing state),
         will be based on the rates, charges and procedures of the billing state
         and subject to that jurisdiction's regulations.

5.11.4   SBC Telco may modify rates to this Agreement to simplify the SBC
         Telcos' rates or due to changes in the billing and collection
         regulatory environment or changes in the SBC Telcos' costs in providing
         Billing and Collection Services only once per year during the Term of
         Agreement. Such rate increases shall not exceed more than 10% of the
         current rate. The Parties must mutually agree to the rate increase,
         however, if Customer is unwilling to agree, this Agreement will
         terminate thirty (30) days after the rate increase becomes effective.
         The limitations in this paragraph shall not apply to increases solely
         and directly due to postal increases or rate changes to tariffed rates.

5.11.5   When bill rendering services are ordered, the Customer will make an
         upfront initial "start-up" payment as indicated on Exhibit A. Such
         payment will be included with the Customer's submission of this signed
         Agreement to SBC Telco. A separate start-up charge is associated with
         Invoice Billing as indicated on Exhibit A. Notwithstanding the above,
         Customers who are renewing existing bill rendering services are not
         subject to additional initial start-up payments.

5.11.6   The Customer purchasing bill rendering services will make a guaranteed
         minimum purchase of services from SBC Telco under this Agreement, as
         specified in Exhibit A.

5.11.7   SWBT, AMERITECH, SNET ONLY - Calculation of the monthly minimum
         purchase of services will be based on the Customer's monthly billed
         volumes. A comparison will be made of actual amount billed to the
         Customer and the monthly minimum purchase of services. The Customer
         will pay no less than the applicable monthly minimum purchase of
         services for that month. Minimums will be tracked on a monthly basis.

5.11.8   PACIFIC BELL AND NEVADA BELL ONLY - Calculation of the annual
         (consecutive 12 months) minimum purchase of services shall be based on
         the Customer's annual billed volumes. A comparison will be made of
         actual amount billed to the Customer and the minimum annual purchase of
         services. This comparison will be made ninety (90) days after

                Agreement under Section 9. For the purposes of this Section,
                "certification" includes any registration of similar filing

                        SBC Telco.

                6.4.2   Neither Customer nor its Clients, nor their employees,
                        contractors or agents, shall make any misrepresentations
                        concerning their affiliation with the SBC Telcos or any
                        SBC Telco Affiliates, or imply that products or services

                        Telco in investigating such violation, as well as for
                        any lost profits or costs associated with the loss or
                        restoral of End User accounts.

                6.4.4   Customer agrees that a continued violation of this
                        Section would cause the SBC Telcos or their Affiliates
                        irreparable injury for which they would have no
                        adequate remedy at law, and that the SBC Telcos or

                           loss, cost, claim, liability, damage or expense
                           (including reasonable attorney's fees) to Third
                           Parties, relating to or arising out of negligence,
                           misconduct, or breach of this Agreement by the
                           Indemnified Party, its employees, agents, or
                           contractors, and associated with this Agreement. In
                           addition, the Indemnifying Party will defend any

                           liability, damage or expense relating to or arising
                           out of the negligence, misconduct, or breach of this

                           reasonable attorney's fees) arising from the accuracy
                           of the billing charges submitted by the Customer to

                           Indemnified Party alleges that the Indemnifying Party
                           is responsible under this section and tender the
                           defense of such claim, lawsuit or demand to the
                           Indemnifying Party. The Indemnified Party also will
                           cooperate in every reasonable manner with the defense
                           or settlement of such claim, demand or lawsuit. The
                           Indemnifying Party will not be liable under this
                           subparagraph for settlements by the Indemnified Party
                           of any claim, demand or lawsuit unless the
                           Indemnifying Party has approved the settlement in
                           advance or unless the defense of the claim, demand or
                           lawsuit has been tendered to the Indemnifying Party
                           in writing and the Indemnifying Party has failed
                           promptly to undertake the defense.

EXHIBITS - Billing and Collections Services Operating Agreement by and among
           BellSouth Telecommunications, Inc. and Cingular Wireless LLC,
           effective September 1, 2003

                                                                   EXHIBIT 10.62

                  10.3     Notwithstanding any other provision of this Section
                           10, the parties acknowledge that SBC Telco has no
                           knowledge of the validity of message payment
                           obligations (billing charges) sent to SBC Telco for
                           billing and collections under this Agreement, and
                           that SBC Telco therefore strictly relies upon the
                           Customer to forward only correct billing charges that
                           can be, if necessary, substantiated in a court of
                           law.

                  10.4     Upon request, the Customer will provide to SBC Telco
                           all evidence needed to sustain billing charges
                           challenged by an End User, and SBC Telco may adjust
                           said charges with recourse if the Customer does not
                           provide all evidence needed to substantiate billing
                           charges which are challenged by an End User. SBC may
                           adjust any billing charges challenged by an End User
                           if in SBC Telco's sole opinion, the circumstances
                           involved in the dispute, should be handled between
                           the Customer and the End User. The Customer
                           certifies, when forwarding billing charges to SBC
                           Telco, that said charges are true and correct, and
                           accurately reflect proper charges legally owed by the
                           billed Party (End User). This Customer certification
                           of validity shall apply to all billing charges
                           forwarded to SBC Telco under this Agreement by the
                           Customer from whatever source. Should SBC Telco incur
                           liability for billing and collection of any billing
                           charges forwarded by the Customer, the Customer will
                           defend, indemnify, and hold harmless SBC Telco for
                           any loss, cost, claim, damage or expense (including
                           reasonable attorney's fees) arising from such billing
                           and collection.

                  10.5     The Customer shall indemnify SBC Telco for any claim,
                           loss, damage, expense (including reasonable
                           attorney's fees) or liability arising in whole or in
                           part from Customer's infringement of any patent,
                           trademark, copyright, trade secret or other
                           proprietary interest associated with Services
                           provided by this Agreement.

                  10.6     Each Party shall defend or settle, at its own
                           expense, any action or suit against the other for
                           which it is responsible under this clause. Each Party
                           shall notify the other promptly of any claim of
                           infringement for which the other is responsible, and
                           shall cooperate with the other in every reasonable
                           way to facilitate the defense of any such claim.

         11.0     PROPRIETARY INFORMATION

                  Attached to this Agreement, as Exhibit F, is the Parties'
                  understanding with respect to Proprietary Information.

         12.0     FORCE MAJEURE

                  Neither Party shall be liable or deemed to be in default
                  under this Agreement for any delay or failure to perform
                  resulting from (i) accidents, fire, labor disputes, epidemics,

                  shall extend performance accordingly or excuse performance, in
                  whole or in part, as may be reasonable. Customer may terminate
                  for a Force Majeure Condition which continues for more than
                  sixty (60) days as provided in Section 9, Termination of
                  Service.

                  provisions may be added by written agreement signed by or on

                  otherwise provided herein. No amendment or waiver of any
                  provision of this Agreement and no consent to any default
                  under this Agreement shall be effective unless the same shall
                  be in writing and signed by the Party against whom such
                  amendment, waiver or consent is claimed. In addition, no
                  course of dealing or failure of any Party to strictly enforce
                  any term, right or condition of this Agreement shall be
                  construed as a waiver or such term, right or condition.

         14.0     ASSIGNMENT

                  14.1     Neither Party shall assign any right or obligation
                           under this Agreement without the other Party's prior
                           written consent. Any attempted assignment shall be

                           Telco at least thirty (30) days prior written notice
                           of such assignment, (ii) such assignment shall not
                           impose upon SBC Telco obligations to the assignee
                           other than the payment of such moneys and (iii) such
                           assignment shall not result in the filing or claim of
                           a security interest in any PAR offered to SBC Telco
                           for purchase under this Agreement.

                                    equal to or greater than that of the
                                    assignor.

                           Any assignment under this Section shall not require
                           the consent of the other Party, but the assigning
                           Party shall provide written notice to the other Party

                           scope of the Services which SBC Telco is obligated to
                           provide by more than ten percent (10%). If the

                           agreements between the Parties will survive such
                           merger or consolidation and govern the billing and
                           collection services provided thereafter by SBC Telco
                           to the surviving company.

                  14.4     Without limiting the generality of the forgoing, this
                           Agreement shall be binding upon and shall inure to

                  and demands that may be given by a Party to the other Party
                  under this Agreement shall be in writing and shall be deemed
                  to have been duly given 1) on the date delivered in person or

                  electronically provided that the receiving machine delivers
                  confirmation to the sender and receipt is verified through a
                  phone call; or, 4) on the date transmitted via electronic
                  mail. If electronic mail delivery is selected as the method of
                  giving notice under this section, the electronic mail record
                  of receipt is binding as appropriate notification. If personal
                  delivery is selected as the method of giving notice under this
                  section, a receipt of such delivery shall be obtained. Mailing
                  addresses for notices shall be as indicated on the Customer's
                  current Implementation Forms. The Parties will officially
                  indicate their electronic notice name and address if this

                  charges to Customer to have their billing messages included by
                  SBC Telco on End User telephone bills.

                  hereunder or related hereto, whether in contract or tort,

                  the portion of the Agreement that is invalid. In all other
                  respects this Agreement will stand as if such invalid or
                  unenforceable provision had not been a part thereof, and the
                  remainder of the Agreement shall remain in full force and
                  effect. Additionally, the Parties shall endeavor to replace
                  the provision with a valid and enforceable provision
                  acceptable to both Parties which so far as possible achieves
                  the same economic and other benefits for the Parties as the
                  severed provision was intended to achieve.

         19.0     ENTIRE AGREEMENT

                  This Agreement (including all Appendices, Exhibits, and/or
                  Attachments hereto) constitutes the entire agreement between
                  the Parties and supersedes all prior agreements, oral or
                  written representations, statements, negotiations, proposals
                  and undertakings with respect to the subject matter hereof.
                  Except as otherwise provided in this Agreement, no
                  modification, amendment, supplement to or waiver of this
                  Agreement or any of its provisions shall be binding upon the
                  Parties unless made in writing and duly signed by authorized
                  representatives of both Parties.

         20.0     HEADINGS

                  The headings in this Agreement are for convenience and shall
                  not be construed to define or limit any of the terms herein

                                    procedures, the SBC Telco determines are

                           Purchase of Accounts Receivable, SBC Telco will add
                           to the Amount Due the Customer.

                           Uncollectible True-Up Amounts are amounts resulting
                           from quarterly true-up calculations as defined in

         1.1.3.   Uncollectible Bad Debt Allowance (Discounted)

                  For each settlement, SBC Telco will subtract an uncollectible
                  bad debt allowance amount for Uncollectibles from the Total
                  Current Billable Amount, adjusted by Recourse Adjustments,
                  Billed Taxes, Surcharges and Unbillables. Uncollectibles are
                  amounts billed by SBC Telco to End Users on final End User
                  bills that are added to the Uncollectible (realized) Accounts
                  of SBC Telco. SBC Telco will determine the Customer's
                  uncollectible bad debt allowance amount for Uncollectibles for
                  each settlement by multiplying the Total Current Billable
                  Amount, adjusted by Recourse Adjustments, Billed Taxes,
                  Surcharges and Unbillables by the Customer uncollectible

                           (nine) months of realized uncollectible monthly
                           activity, the Customer's uncollectible factor will be

                           Telco by the Customer.

                  1.1.3.2. Existing Customers

                           To determine the Customer uncollectible bad debt
                           allowance factor, SBC Telco will determine from its
                           bill records the dollar amount billed on the final
                           End User bills which have deemed as uncollectible.
                           These amounts are added to the realized uncollectible
                           accounts (uncollectible amount) for the most recent
                           quarterly period as defined by SBC Telco. This
                           uncollectible amount will include adjustments to
                           account for any payments received by SBC Telco for
                           outstanding final Customer billed amounts that were
                           declared uncollectible prior to the most recent
                           quarter. The uncollectible amount will not include
                           uncollected late payment charges applied to the End
                           User bill.

                  1.1.3.3. An uncollectible apportionment system will be used by
                           SBC Telco each month to determine the total realized
                           uncollectible amounts for each Customer which is
                           provided Bill Processing Service by SBC Telco.

                  1.1.3.4. SWBT only - The realized uncollectible amount for the
                           Customer determined through the apportionment system,
                           will be divided by the Total Current Billable Amount,
                           plus or minus returns, plus rebills, plus or minus
                           Recourse Adjustments, plus taxes for the same quarter
                           to develop the Customer uncollectible bad debt
                           allowance factor.

                           PB/NB only - The realized uncollectible amount for
                           the Customer determined through the apportionment
                           system, will be divided by the Total Current Billable
                           Amount, plus or minus returns, plus rebills, plus or
                           minus Recourse Adjustments, for the same quarter to
                           develop the Customer uncollectible bad debt allowance
                           factor.

                  1.1.3.5. This uncollectible apportionment system will utilize
                           actual Customer realized uncollectible amount from
                           End User accounts in order to determine realized

                           bad debt allowance factor is determined in the
                           succeeding study period.

                  1.1.3.7. In the event of negative or zero uncollectible bad
                           debt allowance factor occurs, SBC Telco may utilize
                           either an industry average factor, the Customer's
                           prior quarter factor, or another surrogate factor
                           which represents the Customer's prior uncollectible
                           history.

                  1.1.3.8. Notwithstanding the above, SBC Telco retains the
                           right to adjust the Customer's uncollectible bad debt
                           allowance factor should the Customer's
                           uncollectibles, adjustments and/or billable revenues
                           fluctuate to such an extent as to appear unstable and
                           insufficient to cover projected write-offs, or
                           abruptly change.

         1.1.4.   Uncollectible True-Up

                  SBC Telco will determine the time at which the history of the
                  Customer's realized uncollectibles is sufficient to establish
                  the Customer specific uncollectible bad debt allowance factor
                  (normally 9 to 12 months of realized uncollectible monthly
                  activity). After this Customer specific factor has been
                  developed and applied for a quarterly period, the following
                  uncollectible true-up procedure will be implemented.

                  1.1.4.1. During the quarterly period, if the realized
                           uncollectible (write-offs) plus the required
                           uncollectible reserve amount as defined below in
                           Section 1.1.5 (reserve) differ from the total
                           uncollectible bad debt allowance amount discounted
                           from each settlement (discounted uncollectibles) plus
                           the reserve currently held by SBC Telco, a true-up
                           amount will be calculated. This difference shall
                           equal the true-up amount. SBC Telco will net the
                           true-up amount from the Purchase of Accounts
                           Receivable Amount due the Customer. The formula for
                           the true-up is as follows:

                           Total Current Quarter's Realized Uncollectibles

                           +        The current quarter's required reserve
                                    amount

                           ----------------------------------------------------

                           = Total current quarter's realized uncollectible and
                           reserve requirement

                           -        The appropriate quarter's discounted
                                    uncollectibles

                           negative true-up amount will be due the Customer.

                  1.1.4.2. This formula allows for an actual true-up on realized
                           uncollectibles and the maintenance of an ongoing
                           required reserve amount.

                  1.1.4.3. The true-up amount will be calculated at the end of

                           period. The true-up settlement will be included in

                           the Estimated Bad Debt, SBC Telco will deduct the
                           difference from the next available purchase of
                           accounts receivable or, if the next scheduled
                           purchase of accounts receivable is less than the
                           difference, SBC Telco may issue a separate invoice to
                           the Customer for the difference. The Customer will
                           pay such separate invoice within 5 business days of
                           receipt. In the event the Customer fails to pay the
                           separate invoice within 5 business days of receipt,
                           SBC Telco may immediately discontinue any or all

                  1.1.5.   Reserve Requirement

                           SBC Telco will apply the following procedures in
                           calculating the required reserve amount:

                           1.1.5.1. Until such time as SBC Telco has established
                                    a Customer specific uncollectible factor,
                                    the reserve requirement will be based on no
                                    less than 50% of the largest one month's
                                    billings submitted to SBC Telco by the
                                    Customer.

                           1.1.5.2. For Customers whose total adjustments exceed
                                    10% of the Customer's billed revenues in any
                                    one (1) month or should the Customer's
                                    uncollectibles adjustments and/or billed
                                    revenues fluctuate to an extent as to appear
                                    unstable or insufficient to cover projected
                                    write-offs, or abruptly change, the required
                                    reserve amount will be calculated as
                                    follows:

                                    Total realized uncollectibles for the
                                    current quarterly period x (multiplied) .667

                                             experienced in the prior three
                                             months of billings with respect to

                                             Telco's uncollectible system on

                                    and will be determined by calculating the
                                    total realized uncollectibles for the
                                    current quarterly period x (multiplied)

                                    term of the Agreement (less any reduction of
                                    time for service start up) x (multiplied)
                                    one-twelfth (1/12) of the annual required

                                             charges

                                    -------------------------------------------

                                    =        Required Reserve Amount

                                    A positive amount will be calculated into
                                    the Customer's reserve requirement. A

                                    of service.

                                    sole discretion reserves the right to

                  1.1.9.   Payment Detail

                           Any draft payment to the Customer from SBC Telco must
                           be accompanied by the reference number utilized by
                           SBC Telco for the Purchase of Accounts Receivable
                           Statement being paid.

                  1.1.10.  Late Payment Charge

                           Any payment received by the Customer after the
                           payment date or any payment received in funds, which
                           are not immediately available to the Customer on the
                           payment date, will be subject to a late payment
                           charge. The late payment charge shall be the portion
                           of the Amount Due the Customer (as defined in 1.1.)
                           received after the payment date times a late factor.
                           The late factor shall be six percent (6%) per annum
                           prorated on a daily basis (6% divided by 365), or the
                           maximum rate allowed by law in each state
                           jurisdiction, whichever is less. Any late payment
                           charge may be remitted separately to the Customer or
                           at SBC Telco's option combined with a Purchase of
                           Accounts Receivable payment.

                  1.1.11.  Late Payment Resulting from Bank Error

                           Any late payment resulting from bank error will not
                           be subject to the late payment charge provided SBC
                           Telco can verify that it was not at fault. Rather,
                           the discrepancy will be resolved by the bank(s)
                           involved. It is the responsibility of SBC Telco to
                           notify the bank(s) involved and coordinate resolution
                           of the discrepancy.

                  1.1.12.  Negative Amount due the Customer

                           The Customer and SBC Telco agree that in the event
                           the calculation of any Purchase of Accounts
                           Receivable results in a negative amount due the
                           Customer, SBC Telco may at its sole discretion 1)
                           recalculate and reduce the amount of prior pending
                           accounts receivable purchase(s) by the current
                           negative amount due, or 2) hold payment of any
                           pending account receivable purchase(s), otherwise due
                           the Customer, without penalty until such time as the
                           Customer submits new billings which are sufficient to
                           result in SBC Telco's calculation of a subsequent
                           Purchase of Accounts Receivable with a positive
                           amount due the Customer, taking into consideration
                           the negative amount due from prior purchase(s), or 3)
                           issue a bill to the Customer for the amount due SBC
                           Telco.

                                             for payment as defined above will
                                             be due the Customer ten (10)
                                             additional business days from the
                                             date on which a positive or
                                             recalculated amount due is
                                             calculated by SBC Telco or ten (10)
                                             additional business days from the
                                             original payment date, whichever is
                                             later.

                                   1.1.12.2. In addition to any other remedies,
                                             should the Customer fail to submit
                                             new billings in the required weekly
                                             interval to offset the negative
                                             amount due, SBC Telco may apply the
                                             Customer's reserve amount to offset
                                             and proceed with Termination of
                                             Services, as defined in this
                                             Agreement.

         1.2.     AMOUNT DUE SBC TELCO

                  1.2.1.   Calculation of Amount Due SBC Telco

                           The amount due SBC Telco equals all appropriate
                           billing and collection service charges for services
                           provided under this Agreement, or tariffs, including
                           amounts resulting from uncollectible true-up and
                           reserve requirements. These charges will be
                           summarized for the Customer.

                  1.2.2.   Billing Detail

                           Billing and Collection Service charges will be
                           provided to the Customer in the format described in
                           2.0, entitled Customer Billing Statement.

                  1.2.3.   Payment Date

                           1.2.3.1. Based on Pre-End User Billing with netting

                                    If the Amount Due the Customer is less than
                                    the amount due SBC Telco, the difference is
                                    due from the Customer to SBC Telco within 30
                                    days following the date of the Purchase of
                                    Accounts Receivable statement. SBC Telco at
                                    its option may net any negative amount due
                                    SBC Telco as set forth in 1.1.12. If the
                                    payment date would cause payment to be due
                                    on a Saturday, Sunday or SBC Telco/Customer
                                    bank Holiday, payment for the amount due SBC
                                    Telco will be as defined in 1.2.3.2.1. or
                                    1.2.3.2.2.

                  provided to the Customer by SBC Telco) by electronic funds
                  transfer. Any payment to SBC Telco from the Customer less than

                  amount is received by SBC Telco in funds which are not
                  immediately available to SBC Telco, then a late payment charge

                  Statements detailing the amount due SBC Telco (i.e., ASBS
                  reports from SWBT, Open Billing reports from PB/NB) must be
                  received by the Customer at least 20 days prior to the payment
                  date to allow the Customer adequate time to process payment.
                  Statements not received within this timeframe will not be
                  subject to the late payment charge for the number of days the
                  statement was late. It is the Customer's responsibility to
                  prove that a statement was received after the specified
                  timeframe.

         1.2.7.   Late Payment Charge

                  Any payment received by SBC Telco after the payment date or
                  any payment received in funds, which are not immediately
                  available to SBC Telco on the payment date, will be subject to
                  a late payment charge. The late payment charge shall be the
                  portion of the amount due SWBT (as defined in 1.2.1.) received
                  after the payment date multiplied by a late factor. The late
                  factor shall be six (6%) per annum prorated on a daily basis
                  (6% divided by 365), or the maximum rate allowed by law in
                  each state jurisdiction, whichever is less.

                  Any late payment charge may be billed separately by SBC Telco
                  or at SBC Telco's option netted against a Purchase of Accounts
                  Receivable payment.

         1.2.8.   Late Payment Resulting from Bank Error

                  Any late payment resulting from bank error will not be subject
                  to the late payment charge provided the Customer can verify
                  that it was not at fault. Rather, the discrepancy will be
                  resolved by the bank(s) involved. It is the responsibility of
                  the Customer to notify the bank(s) involved and coordinate
                  resolution of the discrepancy.

         1.2.9.   Right to Net

                  1.2.9.1. SBC Telco reserves the right to net against the
                           Customer accounts receivable purchases all Billing

                           received payment on or prior to the Payment Date of
                           the statement detailing the amount due SBC Telco.

                  1.2.9.2. Furthermore, SBC Telco has the right to net
                           outstanding non-Billing and Collection Service
                           charges, either billed on the same billing statement
                           as Billing and Collection Services charges or
                           separately billed, to the Customer's accounts
                           receivable purchases for those charges for which

                           Customer if such netting is required.

                  1.2.9.4. Should the Customer fail to submit new billings in
                           the required weekly interval to offset the amount
                           due, SBC Telco may apply the Customer's reserve
                           amount to offset the amount due and proceed with
                           Termination of Service, as defined in this Agreement.

                  Customer will provide data sets or transmissions to the AOC on
                  a prearranged schedule. The AOC edits the data sets for
                  untimely messages. The AOC also edits to assure the data sets
                  balance to totals predetermined by Customer and supplied in
                  the data set trailer records.

                  If there are no edit errors found in the pack header or
                  trailer records, individual message records are edited for
                  acceptability. The AOC purchases all the message records in
                  the pack that are determined to be acceptable.

                  The revenue on the Purchase/Collection of Accounts Receivable
                  Statement(s) will include all revenues accepted from the
                  transmissions for a specific journal month.

                  The revenue on the Purchase/Collection of Accounts Receivable

                                                                       Ameritech

         B.       Total Billed Taxes/Surcharges (AOC-generated)

                  Billed Taxes include all AOC-generated Federal, State, and
                  Local taxes and additional charges due to taxes that have been
                  billed to the End User. Surcharge amounts include all amounts
                  billed to the End User as directed by Customer.

         C.       Recoursed Adjustments, Duplicates, Unbillables, and Rebills

                  1.       Recoursed Adjustments

                           Recoursed Adjustments are amounts that the AOC
                           removes from end user balances and charges back to
                           the Customer via a deduction on the
                           Purchase/Collection of Accounts Receivable Statement.
                           They may be initiated by the Customer or by the end
                           user and include, but are not limited to, adjustments
                           made to end user bills to correct the charges on
                           current or prior bills; lawfully billed amounts
                           removed from end user balances at the direction of
                           the Customer; and disputed billed amounts removed
                           from end user balances.

                  2.       Discounts

                           Discounts are credits to an end user's account and
                           may apply on either an individual message basis or a
                           bulk basis. Discounts are subtracted on the
                           Purchase/Collection of Accounts Receivable Statement.

                  3.       Unbillables

                           Unbillables are messages or invoices which remain
                           unidentified after standard AOC investigation (e.g.
                           messages from a billing telephone number where no
                           account can be found), messages with invalid data
                           which are detected after successful processing of the
                           transmission and which fail standard AOC correction
                           procedures (e.g. invalid NPA NXX RAO combination) or
                           third number and/or collect messages received for
                           billing on an account which includes a "toll billing
                           exception" indicator.

                  4.       Rebills

                           Rebills are End User messages or invoices that the
                           AOC bills again to the same or other End User
                           accounts after having adjusted the message amounts
                           and applicable taxes. The original messages written
                           off

                                                                       Exhibit B
                                                                       Ameritech

                  resulted in an Adjustment to End Users' accounts and
                  Adjustment to the Purchase/Collection of Accounts Receivable
                  Statement. Therefore, the rebills must be added back into the
                  Purchase/Collection of Accounts Receivable Statement.

                  The Federal, State, or Local taxes associated with the rebill
                  would be included in the "Total Billed Taxes" portion of the
                  Purchase/Collection of Accounts Receivable Statement.

         D.       Uncollectible Bad Debt Allowance (for Bad Debt on Accounts
                  Which Have Received Final Bills)

                  The AOC will subtract on the Purchase/Collection of Accounts
                  Receivable Statement an amount for Anticipated Uncollectibles.
                  Anticipated Uncollectibles are estimated amounts representing
                  the portion of the Total Revenue Accepted, plus or minus Taxes
                  and Surcharges, Recoursed Adjustments, Duplicates,
                  Unbillables, and Rebills - which the AOC expects will
                  ultimately become Realized Uncollectibles.

                  Realized Uncollectibles are amounts lawfully billed to End
                  Users by the AOC, which, after standard intervals and
                  application of standard collection procedures, the AOC
                  determines to be impracticable of collection and which are
                  added to the AOC's Realized Uncollectible Accounts and
                  identified with Customer.

                  The AOC will determine the amounts for Anticipated
                  Uncollectibles by multiplying the Total Revenue Accepted, plus
                  or minus adjustments, by the Uncollectible Factor, rounded to
                  the nearest 1/100,000th. The Uncollectible Factor will be
                  determined as described in subsections 1 to 3 as follows:

                  1.       Uncollectible Factor Initial Period (New Billing and
                           Collection Customer only)

                           At the time a new Customer orders Billing and
                           Collection Services, the AOC will determine the
                           Customer's Uncollectible Factor for the Initial
                           Period. The Initial Period shall be the first nine
                           months for which the Customer is provided Billing and
                           Collection Services if the ninth month is the last
                           month in a calendar quarter (i.e., March, June,
                           September, or December). If the ninth month is the
                           first or second month in a calendar quarter, then the
                           Initial Period shall

                                                                       Exhibit B
                                                                       Ameritech

                           be the first eight or ten months for which the
                           Customer orders such service.

                  2.       Uncollectible Factor - Subsequent Periods

                           At the end of the Initial Period that Billing and
                           Collection Services are provided to the new Customer,
                           and at three-month intervals thereafter, the AOC will
                           revise the Uncollectible Factor to be used in
                           determining the Anticipated Uncollectible amounts for
                           the ensuing three-month period. Existing Customers,
                           who extend the term of their billing agreement(s),
                           will not begin a new nine-month initial period.
                           Rather, their existing Uncollectible Factor, as may
                           be updated at the previously established quarterly
                           intervals, will be carried forward to the new or
                           extended agreement. Where the AOC and Customer enter
                           into a new billing agreement, use of the existing
                           Uncollectible Factor and the previously established
                           quarterly intervals shall not be construed to
                           incorporate by reference any terms or conditions of
                           any previous Billing and Collections agreement
                           between the AOC and Customer.

                  3.       Calculation of the Uncollectible Factor

                           The Uncollectible Factor will be revised as follows:

                           (a)      The AOC will determine the total amount of
                                    all End User billing which, after standard
                                    intervals and application of standard
                                    collection procedures, was written off to
                                    the Realized Uncollectible Accounts of the
                                    AOC during the most recent three-month
                                    period. This Realized Uncollectible amount
                                    will reflect any payments, applicable
                                    deposits, and accrued interest converted to
                                    payments, or Recoursed Adjustments as
                                    described in Section 4.1.1.C preceding,
                                    which were applied during the most recent
                                    three-month period to End User accounts
                                    whose unpaid balances have been included in
                                    the Realized Uncollectible amounts for the
                                    same or earlier periods.

                           (b)      This total Realized Uncollectible amount
                                    will be used by the AOC in an apportionment
                                    study to determine the Uncollectible Bad
                                    Debt Allowance for each billing entity
                                    during the three-month period. Apportionment
                                    percentages used to determine each entity's
                                    Realized Uncollectibles will be based on the
                                    proportion of charges for those end

                                    three-month period.

                           (c)      Customer's Realized Uncollectible amount in
                                    the AOC for the most recent three-month
                                    period will be divided by Customer's
                                    Adjusted Revenue, in such AOC, plus or minus
                                    adjustments, for the three-month period
                                    ending six (6) months prior to the end of
                                    the most recent three-month period. The
                                    result of this calculation will be the
                                    Uncollectible Factor to be used by the AOC
                                    in the ensuing three-month period.

                           (d)      This factor will be used by the AOC as

                                    The AOC will true-up the difference between
                                    the amount of Anticipated Uncollectibles
                                    (Allowance for Uncollectibles) withheld and

                                    actually resulted. The difference will be
                                    the Uncollectible Settlement True-Up. If the
                                    Realized Uncollectibles exceed the

                                    Customer. If the Anticipated Uncollectibles
                                    exceed the Realized Uncollectibles, the
                                    difference will be added to the Amount Due
                                    to the Customer.

                                    The True-Up Settlement will be implemented
                                    in the month following the end of the
                                    Initial Period that Billing and Collection
                                    Services are provided to a new Customer. The
                                    AOC will subtract the sum of the Realized
                                    Uncollectibles incurred during the Initial
                                    Period from the sum of the Anticipated
                                    Uncollectibles (Allowance for
                                    Uncollectibles) which were withheld during
                                    the period extending from the seventh
                                    previous month back through the first month
                                    of the initial period. The difference will
                                    be the True-Up Settlement that will appear
                                    on the Purchase/Collection of

                                                                       Ameritech

                                    Accounts Receivable Statement issued the
                                    month following the end of the Initial
                                    Period.

                                    For example, if the Initial Period is
                                    January through September, the True-Up
                                    Settlement will be implemented on the
                                    October Purchase/Collection of Accounts
                                    Receivable Statement. The sum of the
                                    Realized Uncollectibles for January through
                                    September will be subtracted from the sum of
                                    the Anticipated Uncollectibles for January
                                    through March. The difference will be the
                                    True-Up Settlement amount that will appear
                                    on the October Purchase/Collection of
                                    Accounts Receivable Statement.

                                    After settling for the Initial Period, the
                                    True-Up Settlement will continue on a
                                    monthly basis. The amount of Realized
                                    Uncollectibles for the first previous month
                                    will be subtracted from the amount of
                                    Anticipated Uncollectibles for the fourth
                                    previous month. The difference will appear
                                    on the Purchase/Collection of Accounts
                                    Receivable Statement as the True-Up
                                    Settlement for the fourth previous month.

                                    For example, after settling for the Initial
                                    Period on the October Purchase/Collection of
                                    Accounts Receivable Statement, the True-Up
                                    Settlement for the November
                                    Purchase/Collection Statement will be
                                    calculated as follows: The amount of
                                    Realized Uncollectibles for October will be
                                    subtracted from the amount of Anticipated
                                    Uncollectibles for July. The difference will
                                    be reflected on the November
                                    Purchase/Collection of Accounts Receivable
                                    Statement as the True-Up Settlement for
                                    July.

                                    The AOC will apply the following procedures
                                    in calculating the required reserve amount:

                                    1.       Until such time as the AOC has
                                             established a Customer specific
                                             uncollectible factor, the reserve
                                             requirement will be based on no
                                             less than fifty percent (50%) of
                                             the largest one month's billings
                                             submitted to the AOC by the
                                             Customer.

                                    2.       For Customers whose total
                                             adjustments exceed 10% of the
                                             Customer's billed (accepted)
                                             revenues in any one (1) month or
                                             should the Customer's

                                    3.       The required reserve amount for

                                             defined in F.1 and F.2 above will
                                             be established and maintained by
                                             AOC as a current reserve and will
                                             be determined by calculating the
                                             total realized uncollectibles for
                                             the current quarterly period x

                                    4.       Notwithstanding the above, AOC at
                                             its sole discretion reserves the
                                             right to increase the reserve
                                             amount, if the Customer's
                                             uncollectibles, adjustments, and/or
                                             billable revenues fluctuate to such
                                             an extent that the reserve no
                                             longer appears sufficient to cover
                                             the projected write-offs. This may
                                             be accomplished by increasing the
                                             bad debt allowance factor and/or by
                                             withholding payments due to the
                                             Customer, as AOC shall deem
                                             necessary to cover the risk
                                             involved or require the Customer to
                                             fund the increased reserve amount.
                                             AOC can satisfy the reserve
                                             requirement for any AOC by netting
                                             a customer's PAR from any other
                                             AOC.

                                    5.       During the quarterly period, if the
                                             required uncollectible reserve
                                             amounts as defined above in Section
                                             F (Reserve) differ from the total
                                             Reserve currently held by AOC, a
                                             true-up amount will be calculated.
                                             This difference shall equal the
                                             Reserve True-Up amount. AOC will
                                             net the Reserve True-Up amount from
                                             the Purchase of Accounts Receivable
                                             Amount due the Customer. The
                                             formula for the Reserve true-up is
                                             as follows:

                                    Reserve True-up Formula

                                    + Total Current Quarter's required reserve
                                      amount

                                    - Prior quarter's reserve amount held by AOC

                                    AOC may continue to hold the Reserve amount

                           The AOC will calculate the Gross Receipts Tax amount

                  Billing and Collection Services to Customer, the AOC shall
                  continue to determine Recoursed Adjustments as set forth in
                  Section 4.1.1.C preceding, which are made during this one-year
                  period. The AOC will also continue to determine the Realized
                  Uncollectible amounts that occur during this one-year period.

                  The AOC will continue to provide the Customer the Purchase of
                  Accounts Receivable Statement during this one-year period and
                  will pay any net amounts owed to Customer. If the "Net Due" is
                  negative, amounts are to be paid within twenty (20) calendar
                  days from the Customer's receipt of the Purchase of Accounts
                  Receivable Statement Date, interest will be charged at the
                  rate described in Paragraph 4.1.7.

                  A.       Recoursed Adjustments

                           If a Reserve has not been established under Section
                           4.1.1.F in a sufficient amount to cover anticipated
                           Recoursed Adjustments, the AOC will subtract from the
                           last regular Purchase of Accounts Receivable
                           Statement(s) an amount for anticipated Recoursed
                           Adjustments during this one-year period. The AOC will
                           calculate the amount to be subtracted by multiplying
                           the total Recoursed Adjustments for the previous
                           twelve (12) months, as detailed on the
                           Purchase/Collection of Accounts Receivable
                           Statements,

                           times 25%. If in the AOC's discretion, the Reserve
                           established under Section 4.1.1.G preceding is
                           insufficient to cover anticipated Recoursed
                           Adjustments during this one year period, then the AOC
                           may increase the amount of the Reserve consistent
                           with the calculation under this Section 4.1.2.A.

                           This amount subtracted for anticipated Recoursed
                           Adjustments will be used on a monthly basis as an
                           offset against Recoursed Adjustments incurred by End
                           User accounts on behalf of Customer during the
                           one-year period. Customer may make additional
                           payments for anticipated Recoursed Adjustments.

                           After the one-year period has elapsed, the AOC will
                           determine the settlement amount by which the
                           Recoursed Adjustments exceeded or were less than the
                           anticipated Recoursed Adjustment. The AOC will
                           prepare a Settlement Statement one month after the
                           one-year period has elapsed which will reflect the
                           final settlement amount. The AOC will provide
                           Customer a copy of that statement and will make
                           available to Customer all documentation used in
                           preparation of the Settlement Statement.

                           The AOC will pay Customer the amount by which the
                           actual Recoursed Adjustments are less than the
                           anticipated Recoursed Adjustments or the Reserve
                           amount, as applicable. Customer will pay the AOC the
                           amount by which actual Recoursed Adjustments exceeded
                           the anticipated Recoursed Adjustments or Reserve
                           amount. Amounts owed are to be paid within twenty
                           (20) calendar days of receipt of the Settlement
                           Statement (Payment Date).

                  B.       Uncollectibles

                           The true-up settlement will continue on a monthly
                           basis during the one-year period to settle for the
                           last six months of billing prior to the end of the
                           contract.

                           The AOC will make twelve (12) additional monthly
                           true-ups. For the first six (6) months, the AOC will
                           subtract the amount of Realized Uncollectibles from
                           the amount of Anticipated Uncollectibles held in
                           reserve. The difference will be included in the
                           True-Up Settlement Section on the Purchase of
                           Accounts Receivable Statement(s).

                           The AOC will pay the Customer the amount by which the
                           Anticipated Uncollectibles exceeded the Realized
                           Uncollectibles. The Customer will pay the AOC the

                           amount by which Realized Uncollectibles exceeded
                           Anticipated Uncollectibles.

                           At the end of the one-year period, the AOC will pay
                           the Customer the amount by which the Anticipated
                           Uncollectibles exceed the Realized Uncollectibles.

                  C.       Special Anticipated Uncollectibles

                           The AOC may subtract from the last regular Purchase
                           of Accounts Receivable Statement(s) an amount for a
                           Special Anticipated Uncollectible amount. The AOC and
                           Customer will agree upon the amount to be subtracted.

                           This Special Anticipated Uncollectible Amount will be
                           used on a monthly basis as an offset against Realized
                           Uncollectibles incurred during the one-year period.

                           If the Special Anticipated Uncollectible Amount does
                           not occur before the one-year period has elapsed, the
                           AOC shall pay the Customer the Unused Special
                           Anticipated Uncollectible Amount.

                  D.       Unbillables

                           The Unbillable Amount will be subtracted on a monthly
                           basis during the one-year period. The Unbillable
                           Amount will be included on the Purchase/Collection of
                           Accounts Receivable Statement(s).

                  E.       Other Collection Fee

                           The Other Collection Fee (outside collection agency
                           fees) will continue to be included on the
                           Purchase/Collection of Accounts Receivable Statement
                           in the True-Up Settlement Section during the one-year
                           period.

                  F.       Netting Against Reserve or Other Amounts Withheld

                           If the Reserve or any amount withheld for a specific
                           type of anticipated adjustments under Section 4.1.2
                           is exhausted during the one year true up period, the
                           AOC may net any amounts owed by Customer for such
                           anticipated adjustment against amounts withheld for
                           any other type of anticipated adjustment.

         4.1.3    Statement of Amount Due the Customer

                  A Statement of Amount Due, e.g., the Purchase/Collection of
                  Accounts Receivable Statement, will be provided to the
                  Customer by the AOC on a monthly basis.

         4.1.4    Payment Date

                  The payment of the Purchase/Collection of Accounts Receivable
                  Statement is paid once per month. The Payment Date is
                  calculated by adding to the transmission receipt the average
                  number of days to bill (15 days for Message Ready, 6 days for
                  Invoice Ready), then adding the lag days (43 days), and then
                  calculating a weighted average of the transmissions. (Refer to
                  Attachment I for an example of the Payment Date Calculation.)

                  If the calculated Payment Date is a Saturday, Sunday, or
                  AOC/Customer bank Holiday, payment for the Net
                  Purchase/Collected Amount will be due to the Customer as
                  follows:

                  A.       If such Payment Date falls on a Sunday or on a
                           Holiday which is observed on a Monday, the Payment
                           Date shall be the first non-Holiday day following
                           such Sunday or Holiday.

                  B.       If such Payment Date falls on a Saturday or on a
                           Holiday which is observed on Tuesday, Wednesday,
                           Thursday, or Friday, the Payment Date shall be the
                           last non-Holiday day preceding such Saturday or
                           Holiday.

         4.1.5    Payment Method

                  Any payment to the Customer from the AOC may be paid by check,
                  or draft to the payee's lock box address, or by electronic
                  funds transfer to a designated bank account. Payment must
                  result in immediately available funds on the Payment Date. If
                  any portion of the Net Purchase/Collected Amount is received
                  by the Customer in funds that are not immediately available to
                  the Customer, then a Late Payment Penalty shall be due the
                  Customer. The AOC will have full responsibility for ensuring
                  that payment is received by the Payment Date.

         4.1.6    Payment Detail

                  Any payment to the Customer from the AOC must identify the
                  Purchase/Collection of Accounts Receivable Statement being
                  paid.

         4.1.7    Late Payment Penalty

                  If any portion of the Net Purchase/Collected Amount is
                  received by the Customer after the Payment Date, or if any
                  portion of the Net Purchase/Collected Amount is received by
                  the Customer in

                  funds which are not immediately available to the Customer,
                  then a Late Payment Penalty shall be due the Customer. The
                  Late Payment Penalty shall be the portion of the Net
                  Purchase/Collected Amount (as defined in Paragraph 4.1.1)
                  received after the Payment Date, times a late factor,
                  compounded daily for the number of calendar days from the
                  Payment Date to and including the date that the funds are made
                  available to the Customer. The factor for each day shall be
                  the lesser of:

                  A.       The highest interest rate (in decimal value) which
                           may be levied by law for commercial transactions in

                  B.       0.000454 per day compounded daily, resulting in an
                           effective annual rate of 18%.

         4.1.8    Late Payment Resulting from Bank Error

                  Any late payment resulting from bank error will not be subject
                  to the Late Payment Penalty provided the AOC can verify that
                  it was not at fault. Rather, the banks involved will resolve
                  the error. It is the responsibility of the AOC to notify the
                  banks involved and coordinate resolution of the error.

4.2      AMOUNT DUE THE AOC

         4.2.1    General

                  A Statement of the Amount Due the AOC will be provided to the
                  Customer by the AOC on a monthly basis. The Amount Due the AOC
                  equals all appropriate Billing and Collection Services charges
                  billed under contract or any applicable tariffs. Access
                  charges are not to be considered a portion of the Amount Due
                  the AOC as part of this Agreement.

         4.2.2    Payment Date

                  The Amount Due the AOC is due from the Customer on the same
                  date as the bill date but in the following month unless the
                  bill is received by the Customer less than twenty (20)

                           Purchase of Accounts Receivable under netting. AOC
                           will apply any late payment penalty incurred by the

                           netting is required.

                  4.2.5.4. Should the Customer fail to submit new billings in

                  Any late payment resulting from bank error will not be subject
                  to the Late Payment Penalty provided the Customer can verify
                  that it was not at fault. Rather, the banks involved will
                  resolve the error. It is the responsibility of the Customer to
                  notify the banks involved and coordinate resolution of the
                  error.

                  agreed period, to process the claim and notify the claiming
                  Party of the claim status. Should the claim, in whole or in
                  part, ultimately be resolved in favor of the claimant, the
                  claiming Party shall be entitled to a financial settlement
                  from the other Party to the extent the claim was sustained. If
                  appropriate, interest on the financial settlement amount shall

                           payee through the date that the
                           overpayment/underpayment was made available to the
                           payer.

                  B.       After written notice to the claiming Party that the
                           claim has been sustained, the total amount of the
                           financial settlement shall be remitted no later than
                           31 calendar days following resolution.

         4.3.4    Retention of Supporting Data Concerning Disputed Amount

                  Both parties shall retain such detailed information as may

                                    Receivable Statement to compensate for
                                    losses resulting from failure of the end
                                    user to pay final bill amounts due.
                                    Derivation of the Uncollectible Bad Debt
                                    Allowance is set forth in Section 5.1.2
                                    below.

                           D.       Quarterly Uncollectible True-up Amount
                                    reflects the amount by which the
                                    Uncollectible Bad Debt Allowance differs
                                    from the net realized uncollectibles.

                           E.       Unbillable messages are messages that cannot
                                    be posted to an end user account.

                           F.       Amount Due Customer represents the Net
                                    Purchase amount for Accounts Receivable.

                  5.1.2.   Derivation of Uncollectible Bad Debt Allowance

                           For each purchase of accounts receivable, SNET shall
                           subtract from the total accounts receivable an amount
                           for uncollectibles, subject to the following process:

                           A.       Initial Factor

                                    The uncollectible percentage will be 5.00%
                                    for the first three (3) full quarters of
                                    billing. At the end of the third full
                                    quarter of billing, a true-up will be
                                    performed and a new factor will be
                                    calculated, and shall be revised for each
                                    calendar quarter thereafter.

                           B.       Factor Calculation

                                    B.1)     Except as provided in B.2 below,
                                             the uncollectible factor will be
                                             determined by dividing Customer's
                                             realized uncollectible by
                                             Customer's total end user revenue
                                             billed for the prior quarter net of
                                             adjustments.

                                    B.2)     If 900 Service messages received
                                             for processing represent thirty
                                             percent (30%) or more of the total
                                             volume of messages received for
                                             processing (without editing) during
                                             a given calendar month then the
                                             uncollectible factor shall be ten
                                             percent (10%) or the factor
                                             calculated pursuant to B.1

                                             above, if the factor calculated
                                             pursuant to B.1 above is greater
                                             than ten percent (10%).

                           C.       Total Realized Uncollectible

                                    The total realized uncollectible is the
                                    amount of final customer bills remaining
                                    unpaid after SNET's standard collection
                                    efforts are completed. (Deposits held by
                                    SNET are applied to final bills when
                                    rendered.) This amount reduced by any
                                    payments received by SNET for outstanding
                                    uncollectibles from prior periods equals the
                                    total net realized uncollectible.

                           D.       Net Realized Uncollectible

                                    Customer's net realized uncollectible is
                                    computed monthly by applying an
                                    apportionment percentage for Customer as
                                    determined by SNET's monthly uncollectible
                                    apportionment study to the total realized
                                    uncollectible for the month.

                           If the factor calculated pursuant to section
                           5.1.2.B.1 is above ten percent (10%), this higher
                           factor shall remain in effect for a given quarter and

                                    withheld from billed revenues, a true-up
                                    amount shall be calculated and either billed
                                    or remitted to the Customer, as appropriate.
                                    The true-up amount shall be calculated by
                                    the end of the month following the close of
                                    each quarter.

                           5.1.3.2. If 900 Service messages received for
                                    processing represent thirty percent (30%) or
                                    more of the total volume of messages
                                    received for processing (without editing)
                                    during a given calendar month (900 first
                                    month of purchase) then the total of all
                                    uncollectible bad debt allowance amounts
                                    shall be accrued for twelve (12) months.
                                    This twelve (12) months of allowance amounts
                                    shall be compared to the total amount of
                                    Customer's realized uncollectibles for all
                                    months prior to the true-up. The true-up
                                    shall be calculated on the twenty-fourth
                                    (24th) month following the 900 first month
                                    of purchase. Subsequent true-ups shall be
                                    calculated every twelve (12) months for the
                                    prior twelve (12) month period.

                  5.1.4.   Final True-ups at Termination

                           5.1.4.1. Upon termination of this Agreement, SNET
                                    shall withhold additional amounts thereby
                                    establishing a reserve to offset any service
                                    related costs and/or charges that may occur
                                    after settlement of Customer's final
                                    submission of Contract Messages. If the
                                    uncollectible bad debt allowance withheld
                                    for the Quarter prior to termination notice
                                    is less than the highest amount withheld
                                    during any Quarter during the previous
                                    eighteen (18) months, SNET shall reduce the
                                    Final purchase of accounts receivable by the
                                    difference. During the period of one (1)
                                    year following the settlement of Customer's
                                    final submission of messages, SNET shall
                                    subtract from the reserve amount any
                                    subsequent service related charges and/or
                                    Customer's Net Realized Uncollectible
                                    amounts. In the event that the service

                                    Realized Uncollectible amounts exceed the
                                    reserve during such one (1) year period,
                                    SNET shall invoice Customer for such excess.
                                    SNET shall, one (1) year following the
                                    settlement of Customer's final submission,
                                    provide Customer with a final accounting and
                                    remit any remaining amounts withheld or
                                    shall invoice Customer as appropriate.

                                    month. The result, using conventional
                                    rounding, will be the Average Transmission
                                    Receipt Date for the month. The cash lag
                                    time period referenced above will be added
                                    to each month's Average Transmission Receipt
                                    Date to determine the actual date of Payment
                                    (wire transfer) from SNET for each month's
                                    total transmissions. A copy of the Average
                                    Transmission Receipt Date calculation,
                                    including the Obligation ID and Serial
                                    Number of all transmissions received, will
                                    be attached to the PAR. For Casual Billing
                                    customers who provide only one transmission
                                    in a calendar month, the transmission
                                    receipt date alone will be utilized to
                                    calculate the Payment Date, and the formula
                                    referenced above will not apply.

                  5.1.6.   Payment Method

                           Any payment to the Customer from SNET will be
                           transmitted by SNET to Customer such that the funds
                           will be available to Customer on the payment date.

                  5.1.7.   Assignment of Accounts Receivable

                           Customer is prohibited from assigning, transferring,
                           selling, exchanging, or giving the accounts
                           receivable to any other entity or person. Any such
                           assignment, transfer, sale, exchange or gift is null
                           and void and will subject Customer to all
                           liabilities, expenses, costs including attorney's
                           fees expended and incurred by SNET in pursuing
                           exclusive ownership to the accounts receivable.

         5.2.     Amount Due SNET

                  5.2.1.   Calculation of Amount Due SNET

                           The amount due SNET is calculated based on the rates
                           contained in Exhibit A, multiplied by the appropriate
                           unit amounts for each month plus any applicable
                           taxes.

NOTE: Invoice Billing is not available in Southern New England Telephone.

1.0      DESCRIPTION OF INVOICE BILLING AND COLLECTION SERVICES

         1.1.     Invoice Billing and Collection Services consist of End User
                  billing data records that have been invoice prepared and sent
                  to SBC Telco as an End User invoice. The invoice will contain
                  call detail that has been rated by the Customer and/or summary
                  records which may contain credits, adjustments, promotions,
                  discounts, other charges and taxes that have been calculated
                  by the Customer. SBC Telco will not be required to perform any
                  additional calculations on the Customer portion of the End
                  User bill.

         1.2.     SBC Telco maintains the sole right to modify and/or require
                  bill presentation formats in a manner consistent with SBC
                  Telco's own bill presentation format.

2.0      TRANSMISSION

         2.1      The Customer will transmit invoices in synchronization with
                  the End User's billing cycle as assigned by SBC Telco. SBC
                  Telco will not be required to alter existing cycles. The
                  Customer will transmit invoices no less than five (5) calendar
                  days prior to SBC Telco's scheduled End User billing period
                  dates (e.g., End User bill period 2/22/05 should be
                  transmitted no later than 2/18/05).

         2.2      Upon receipt of the invoices, SBC Telco will process them in
                  such a way that they may be incorporated with an End User's
                  next bill from SBC Telco according to SBC Telco's normally
                  scheduled billing cycle.

         2.3      If SBC Telco receives transmissions from the Customer for End
                  Users who do not fall in SBC Telco's next billing cycle, SBC
                  Telco will hold the Customer invoice for that End User until
                  the appropriate billing cycle.

         2.4      SBC Telco is to reroute the invoices to the correct SBC Telco
                  billing cycle if the Customer has routed them to the incorrect
                  SBC Telco billing cycle.

         2.5      Invoice formatted messages will not be forwarded to SBC Telco
                  with non-invoice formatted messages. If the Customer submits
                  messages for both invoice and non-invoice presentation on the
                  end user bill, a separate entity (CIC Code) will be required
                  for each.

3.0      UNBILLABLES

         3.1      For purposes of invoice billing error investigation, the
                  invoice will not be split apart by SBC Telco if some of the
                  messages are billable and some are not. The entire invoice
                  will be returned to the Customer with the appropriate error
                  code.

4.0      TAXES

         4.1      The Customer will apply all applicable taxes to the End User
                  invoice data. SBC Telco will not calculate additional taxes on
                  the Customer invoice data. SBC Telco will bill the End User in
                  the format provided by the Customer within its invoice.

         4.2      The Customer acknowledges that SBC Telco will not maintain tax
                  reports for invoice billing. The Customer is solely
                  responsible to maintain all required tax information within
                  their own system.

         4.3      SBC Telco will remit payment to the Customer for the collected
                  taxes as part of the purchase of accounts receivables payment.

         4.4      Billed Taxes are defined for invoice billing to represent the
                  billed taxes (federal, state, and local) associated with all
                  the Customer revenue amounts included in the transmission. The
                  Customer is responsible for determining, calculating, and
                  advising SBC Telco of all taxes.

                                                                        MAY 2001

1.0      SOUTHWESTERN BELL, PACIFIC BELL, AMERITECH

         Complaint thresholds are measured using the number of complaints from
         Customer's End Users that are recorded by the SBC Telco's business
         offices. The complaint threshold for the above SBC Telcos is as
         follows:

<TABLE>
<CAPTION>
         Bills Rendered Per Month                         Complaint Percentage
         ------------------------                         --------------------
         <S>                                              <C>
         80,000 bills rendered or less                             0.5%
         80,001 - 300,000 bills rendered                           0.2%
         300,001 + bills rendered                                  0.1%
</TABLE>

         The formulas for determining specific complaint thresholds will be
         calculated by multiplying the number of bills rendered by the
         appropriate percentage. Therefore, the number of allowable complaints
         for each category would be as follows:

         1.       80,000 bills rendered or less will have a range of 0 - 400
                  complaints per month for two out of every three consecutive
                  months.

         2.       80,001 - 300,000 bills rendered will have a range of 401 - 600
                  complaints per month for two out of every three consecutive
                  months.

         3.       300,001 + bills rendered will have a range beginning with 601
                  complaints per month for two out of every three consecutive
                  months.

                                                                   EXHIBIT 10.62

                                                                       Exhibit E

1.0      GENERAL INFORMATION

         1.1      Billing and Collection Customers can direct promotional,
                  informational or legally required communications/messages to
                  their End Users.

         1.2      The messages that may be printed are the Customer messages
                  that comply with SBC Telco requirements. SBC Telco reserves
                  the right, at its sole discretion to reject any Marketing
                  Message which in SBC Telco's opinion does not conform to the
                  requirements or is advertising a service competitive with a
                  service offered by SBC Telco or one of its affiliates.

         1.3      Customer is limited to two (2) Marketing Messages per End
                  User's monthly bill.

         1.4      SBC Telco will exercise all reasonable efforts to accommodate
                  an accelerated time frame for acceptance of the Customer
                  Marketing Message that is mandated by any governmental
                  authority with appropriate jurisdiction.

         1.5      All information submitted to SBC Telco pursuant to the
                  Marketing Messages procedures as described herein are
                  confidential to the Customer prior to inclusion on the End
                  User bill and will be treated by SBC Telco in a manner
                  consistent with Exhibit F of this Agreement.

2.0      WARRANTY

         2.1      If a Marketing Message is omitted from all or a portion of the
                  applicable End User invoice, and if such omission is due to
                  the fault or negligence of SBC Telco, SBC Telco will include
                  the Marketing Message on the next month's bill following
                  discovery by SBC Telco of the omission. The Customer will
                  timely retransmit the omitted Marketing Message upon
                  notification to do so from SBC Telco in order for SBC Telco to
                  include it on the next month's bills.

                  2.1.1    If due to the time sensitivity of the original
                           marketing Message, that is, having for its principle
                           subject some imminent event (e.g., Mother's Day), and
                           the foregoing remedy will not result in the End Users
                           receiving the Marketing Message before the occurrence
                           of such event, and accordingly the Customer does not
                           desire to utilize the Marketing Message in the next
                           mailing, the Customer will not send the Marketing
                           Message.

                  2.1.2    This Section 2.0 will constitute the Customer's sole
                           and exclusive remedy for the omission of a requested
                           Marketing Message from all or a portion of its End
                           User invoices.

         2.2      The Customer agrees to defend, indemnify, and hold SBC Telco,
                  its officers, directors, and employees harmless from and
                  against all loss, cost, liability, claims,

                  limited to attorneys' fees and costs, resulting from or
                  arising in connection with the Customer's Marketing Messages
                  including but not limited to claims or actions for defamation,
                  trademark, or trade secret infringement, invasion of privacy,
                  or use of false, deceptive, or misleading advertising or
                  practices.

         2.3      SBC Telco assumes no responsibility for reviewing or editing
                  the Customer's Marketing Message.

         2.4      In the event SBC Telco misprints a Marketing Message, SBC
                  Telco will use reasonable efforts to correct the error before
                  the Marketing Message is mailed and at no charge to the
                  Customer. The Customer will timely retransmit the misprinted
                  Marketing Message upon request from SBC Telco if it will help
                  SBC Telco in correcting the error prior to mailing. If a
                  Marketing Message is mailed with a material error caused by
                  SBC Telco, at the Customer's request SBC Telco will in order
                  to correct the error, mail a corrected version of the
                  Marketing Message as retransmitted by the Customer and as
                  agreed upon by both Parties in writing on the next month's
                  bill following discovery by SBC Telco of the misprint. There
                  will be no charge to the Customer for the SBC Telco
                  activities. The corrected version of the Marketing Message
                  will not impact the space available to the Customer for
                  Marketing Message text.

3.0      CHARGES

         3.1      The rates for Marketing Messages will be charged in accordance
                  with the rate elements as provided in Exhibit A of this
                  Agreement.

         3.2      The Customer will be charged for all Marketing Messages after
                  the service has been provided and the charges will be included
                  in the Customer's monthly carrier billing statement. All
                  charges for Marketing Messages are subject to the Late Payment
                  Charges.

1.0      OVERVIEW

         It is recognized by the Parties that, in connection with the B&C
         Services to be provided by the SBC Telcos, the SBC Telcos and the
         Customer will have in their possession and control information in the
         form of data, records, reports, computer programs, end user customer
         lists and other documentation some of which is proprietary to the SBC
         Telcos, the Customer, to both, or to other entities and which is
         considered confidential (hereinafter, "Proprietary Information").

2.0      IDENTIFICATION OF PROPRIETARY INFORMATION COVERED BY THIS EXHIBIT

         The types or categories of the Parties' Proprietary Information
         intended to be covered by and protected under Exhibit F, and which is
         limited to information provided under the terms of this Agreement, are
         specifically designated by each Party in Schedule 1 of Exhibit F. For
         the purpose of defining the respective duties and obligations
         hereunder, the information set forth in Schedule I of Exhibit F is
         categorized and defined as follows:

         A.      SBC Telco Proprietary Information (Exhibit F, Schedule 1,
                 Section I) -- that which is proprietary to the SBC Telcos and
                 will not be used by the Customer, except as necessary for the
                 Customer to perform its obligation under this Agreement or as
                 may otherwise be consented to in writing by the SBC Telcos.

         B.      The Customer's Proprietary Information (Exhibit F, Schedule 1,

                 disciplinary action or termination of employment of its
                 employees or agents) procedures to ensure that its employees or
                 agents are aware of and fulfill the obligation under Exhibit F
                 to hold the Disclosing Party's Proprietary Information in
                 confidence.

                                                                   EXHIBIT 10.62

                                                                       Exhibit F

         B.       Proprietary Information, consistent with the terms herein,
                  will be held in confidence by the Receiving Party and its
                  employees or agents; shall be treated with the same degree of
                  care as the Receiving Party would treat its own Proprietary
                  Information and, consistent therewith, shall not be disclosed
                  to third parties; shall be used only for the purposes stated
                  herein; and may be used or disclosed for other purposes, only
                  upon such terms and conditions as may be mutually agreed upon
                  by the Parties in writing.

         C.       Each Party acknowledges that a Party's Proprietary
                  Information, or third party information held by a Party, may
                  be commingled with Proprietary Information of the other Party.
                  Accordingly the Parties shall, to the extent practicable, use
                  good faith efforts to ensure that its own or third parties'
                  Proprietary Information shall be masked or rendered
                  mechanically inaccessible to the other Party. However, there
                  may be instances in which efforts to mask or screen such
                  Proprietary Information are impracticable, or in which
                  disclosure is inadvertent. In such instances, the Receiving
                  Party will neither use or disclose the Proprietary
                  Information, except as required to fulfill its obligations
                  under this Agreement.

         D.       Unless specifically directed otherwise by the requesting
                  authority, each Party agrees to give notice to the other
                  Party, prior to disclosure of Proprietary Information, of any
                  demand to disclose or provide Proprietary Information of said
                  other Party to other persons, under lawful process, prior to
                  disclosing or furnishing such Proprietary Information, and the
                  Party receiving the demand agrees to reasonably cooperate if
                  the other Party deems it necessary to seek protective
                  arrangements. A Party may provide Proprietary Information of
                  the other Party to implement, effect and enforce this
                  Agreement or the Party's tariffs; to meet the requirements of
                  a court, regulatory body or government agency having
                  jurisdiction over the Party; and will notify the Disclosing
                  Party so as to give the Disclosing Party a reasonable
                  opportunity to object to such disclosure, unless the court,
                  regulatory body or government agency requests that the Party
                  not notify the other Party. Nothing in this Exhibit requires
                  either Party to support or not support the position of any
                  person or entity on the issue of whether any particular
                  Proprietary Information is proprietary under applicable law or
                  this Exhibit.

4.0      PROPRIETARY INFORMATION NOT SUBJECT TO HANDLING RESTRICTIONS

         Notwithstanding any other provision of this Agreement, Proprietary
         Information described in Schedule 1 of Exhibit F shall not be deemed
         confidential or proprietary and the Receiving Party shall have no
         obligation to prevent disclosure of such Proprietary Information if it:

         A.       Is already known to the Receiving Party without restriction as
                  to its confidentiality;

                  of the product, or otherwise, and through no wrongful act of
                  Receiving Party;

         C.       Is received from a third party without similar restriction and
                  without breach of this Exhibit;

         D.       Is independently developed, produced, or generated by
                  Receiving Party;

         E.       Is furnished to a third party by the Disclosing Party without

         F.       Is approved for release by written authorization of the
                  Disclosing Party.

5.0      PERMITTED USES

         Notwithstanding other provisions of this Exhibit, either Party may
         provide, to the end user or any person the end user may designate
         through written notification upon request, any information relevant to
         the end user's account.

         Notwithstanding Section 3.B of Exhibit F, the SBC Telcos or an SBC
         Telco affiliate may use the Customer information, proprietary or
         otherwise, to provide end user inquiry services and to estimate
         facilities usage for jurisdictional separations, and for engineering
         and network planning. Such affiliate will be bound by the terms of this
         Exhibit.

6.0      SBC TELCO NON-PUBLISHED TELEPHONE NUMBERS

         The Customer agrees that it will not disclose any non-published SBC
         Telco end user telephone number to third parties (other than to the end
         user, or to an agent of the Customer). The Customer may disclose a
         non-published number to an agent for the purpose of contacting that end
         user on the Customer's behalf, but the Customer shall bind the agent
         not to disclose the number to anyone other than that end user. In
         addition, the Customer will hold the SBC Telcos harmless from any
         liability or loss resulting from the Customer's improper use of such
         non-published numbers, and shall indemnify the SBC Telcos for such loss
         including costs and fees of litigation.

7.0      FILINGS WITH PUCS OR OTHER REGULATORY AGENCIES

         The Parties agree that this Agreement and its Exhibits will be filed in
         those state jurisdictions that require such filings.

         The Parties acknowledge that this Agreement and its Exhibits contain
         commercially confidential information which may be considered
         proprietary by either or both Parties, and agree to limit distribution
         of the Agreement to those individuals in their respective

         5.1.     SBC Telco will provide Message Data Transmission services that
                  will consist of the transmission of rated Customer message
                  records. SBC Telco maintains the right to terminate without
                  cause Message Data Transmission services upon ninety (90) days
                  written notification to the Customer.

         5.2.     EMI formatted messages from the Customer are required to
                  provide Message Data Transmission. The EMI formatted records
                  must be delivered to a location specified by SBC Telco. It is
                  the responsibility of the Customer to maintain, for a minimum
                  of ninety (90) days from date of receipt by SBC Telco, a
                  back-up file of all call detail records provided to SBC Telco,
                  to allow SWBT to reconstruct lost records. If the Customer
                  fails to maintain a back-up file for reprovisioning of
                  messages to SBC Telco throughout the prescribed time frame,
                  SWBT will not be liable for any such lost records. For
                  transmission from one SBC Telco location to another SBC Telco
                  location, the Customer message data determined to be lost as a
                  result of an error in SBC Telco's Message Data Transmission
                  service, will be recovered by SBC Telco and the Customer's
                  obligation to resupply the data has expired, SBC Telco will
                  estimate the messages' associated revenues as set forth in
                  Paragraph 5.4.8. of the Principal Agreement to this contract.

         Once Cingular Wireless's initial service establishment is complete for
         the service purchased under this agreement they may request

         additional work is required by SBC due to client request such as new
         bill phrases, new product billing, resends of data, etc. All such
         client request will be handled as additional requests.

         Cingular Wireless will provide a written request completely detailing
         the service modifications needed. If more information is required by
         SBC, SBC will provide the client with a list of questions and issues
         within forty-five (45) working days of its receipt of the client's
         request. Once complete, specifications are provided by client, SBC will
         provide a response with a time and cost estimate within forty-five (45)
         working days.

         At the time the Agreement is signed, both SBC and Cingular Wireless
         will submit to each other escalation lists, flow charts, or
         organization charts for conflict resolution.
