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
BETWEEN BELLSOUTH AND CINGULAR

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

The headings of the Sections herein are inserted for convenience only and are not intended to affect the meaning or interpretation of this Agreement.

4. AMENDMENTS AND WAIVERS

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.

BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
BETWEEN BELLSOUTH AND CINGULAR

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 billing and Cingular will not provide charges for an End-User 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 Telephone Number ("BTN") for an End-User and for mapping the Client account invoice to this BTN. BST will not bill charges based on the Client's account identification number for the End-User since it

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.

BETWEEN BELLSOUTH AND CINGULAR

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.

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.

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.

BETWEEN BELLSOUTH AND CINGULAR

A. SERVICE APPROVAL

The Client will submit to BellSouth new and revised Service Programs, 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

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.

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.

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

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.

BILLING AND COLLECTIONS SERVICES OPERATING AGREEMENT
BETWEEN BELLSOUTH AND CINGULAR

Existing payment allocation methodology will be used to apportion End-User payments to Client revenues in the event an 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

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

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.

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.

Any legal proceeding or any other action with respect to BST and with respect to any asserted Liability or additional taxes due by BST shall be under BST's direction, but Client shall be consulted. Any legal proceeding or any other action with respect to Client and with respect to any asserted liability of additional taxes due by Client shall be under Client's direction, but BST shall be consulted. In any event, both Client and BST shall fully cooperate with each other as to the asserted liability. Client shall bear all the costs of any such action undertaken at its specific request. BST shall bear the costs of any such action undertaken absent such a request from Client.

25. FUTURE ENHANCEMENTS

Once the Client's initial service establishment is complete for the service purchased under this Agreement, the Client may request 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.

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.

         ninety (90) days from the date of receipt by SBC
         Telco, a back-up file of all rated messages provided
         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
         not be liable for any such lost records.

5.4.3.   SBC Telco will create and send to the Customer a
         confirmation report that contains information
         regarding acceptances or rejections of the Customer
         data into SBC Telco's data entry processing.

5.4.4.   Rated Customer messages input to the Master File
         Maintenance, which have been received by SBC Telco
         and that SBC Telco cannot bill for any reason, will
         be processed in accordance with SBC Telco's methods
         and procedures. Based on the error encountered, any
         such message may be 1) returned to the Customer
         without review by SBC Telco, or 2) reviewed by SBC
         Telco's Message Investigation Center (see Section
         5.5). Upon completion of the review, the billable
         messages will be posted.

5.4.5.   SBC Telco will return unbillable messages to the
         Customer. Customer messages received by SBC Telco
         that exceed the age of message limits

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.

5.6 PAYMENT AND REMITTANCE PROCESSING

5.6.1    Payment and remittance processing service
         consists of receiving and applying to End User
         accounts sums due to Customer's products and services
         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.

         defined in Exhibit A. Inquiry services include
         acceptance, referral, and/or resolution of End User

                  procedures for its Business Offices to
                  handle, resolve, and/or refer End Users
                  inquiries and claims to Customer.

         5.8.2.2  The SBC Telco will preform standard claim
                  investigation functions for Customer in
                  order to resolve inquiries.

         5.8.2.3  Following standard procedures, the SBC
                  Telco may determine an adjustment is
                  necessary/appropriate, due to a claim
                  related to Customer's service, at its sole
                  discretion, and enter the adjustment into
                  the billing system.

5.8.3    SBC Telco shall not be liable for any loss in the
         Customer's revenues associated with Customer adjusted
         charges initiated by SBC Telco under terms of this
         Agreement.

5.8.4    If Inquiry services are not ordered initially and
         are requested at a later date, a subsequent Start-Up
         fee will be assessed as defined in Exhibit A.

5.9 PURCHASE OF ACCOUNTS RECEIVABLE (PARS)

5.9.1    In order to perform the billing and collection
         function, SBC Telco will purchase the Customer's
         accounts receivables represented by the Customer's
         charges included in bills rendered by SBC Telco. SBC
         Telco's purchase of the Customer's accounts
         receivables shall be with full recourse of all
         charges either uncollected for any reason or disputed
         and credit/refunded back to the end-user customer
         (debit uncollected

                  charges back to the Customer). The parties agree
                  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
                  whole or in part and at any time without liability,
                  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
                  commenced related to Customer's alleged tender of
                  disputed or unauthorized charges to SBC Telco or any
                  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.

5.10     TAXES - MESSAGE READY BILLING

         5.10.1   APPLICATION OF TAXES TO END USERS

                  5.10.1.1 In performing Services, the SBC Telco will

                           and local taxes for jurisdictions outside of
                           the areas in which the SBC Telcos provide
                           local exchange services. All such taxes and
                           charges are referred to in the singular as
                           "Tax" and in the plural as "Taxes." Customer
                           shall be responsible for applying and
                           providing all tax information for state and
                           local tax jurisdiction outside of the areas
                           in which SBC Telcos provide local exchange
                           services.

                  5.10.1.2 Customer authorizes SBC Telco to apply,
                           bill, record and collect all applicable
                           taxes due and payable by Customer's End
                           Users on the service provided by Customer
                           for the period of time coincidental with
                           this Agreement between Customer and SBC
                           Telco.

5.10.1.3 In applying and billing Taxes on behalf of 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.

5.10.2   TAX EXEMPTION

         5.10.2.1 The SBC Telco, in its performance of
                  Services, will apply the exemption status it
                  has determined for the End User and maintain
                  exemption certificate information derived
                  from its exemption certificates. The SBC
                  Telco's exemption certificate information
                  will be used as a basis for exempting End
                  Users from Taxes on Customer's services
                  billed hereunder by SBC Telco. The Customer
                  understands that SBC Telco makes no warranty
                  as to the validity of the End User exemption
                  certificates and that the Customer relies
                  upon SBC Telco's use of the exemption
                  certificate at the Customer's own risk.

         5.10.2.2 The Customer may review information relating
                  to an End User's exemption status and
                  request through the Time and Cost process,
                  as defined in Exhibit A, that SBC Telco
                  reverse the exempt status for purposes of
                  the Customer's service if the Customer
                  provides SBC Telco written instructions to
                  make the status change.

5.10.3   FILING OF TAX RETURNS

         5.10.3.1 Customer shall be solely responsible for
                  filing all returns for Taxes imposed on or
                  with respect to Customer's services billed
                  under this Agreement and paying or remitting
                  all such Taxes and other items and any
                  applicable interest or penalties. Upon
                  reasonable request, SBC Telco shall furnish
                  to Customer on a timely basis all
                  information in SBC Telco's possession that
                  is necessary for Customer to file its Tax
                  returns. Customer shall promptly notify SBC
                  Telco if such information is not received.
                  Requests for such information are subject to
                  T&C Charges in accordance with Exhibit A if
                  SBC Telco must make multiple submissions or
                  use customized formats for Customer.

5.10.4   TAXES IMPOSED ON SERVICES PERFORMED BY THE SBC TELCO

         5.10.4.1 Customer shall be responsible for payment of
                  all sales, use or other taxes of a similar
                  nature imposed on SBC Telco's performance of

                  income tax payable by the SBC Telco on its
                  revenues from such services. SBC Telco
                  agrees to use reasonable efforts to invoice

         deemed to prohibit SBC Telco from invoicing for such
         taxes at a later date to correct errors or omissions
         from the earlier invoice. If any federal, state or
         local jurisdiction notifies SBC Telco that any
         additional sales, use or other taxes (including
         interest, penalties and surcharges thereon) are due
         as a result of SBC Telco's performance under this

         Telco for such tax, interest, penalty and surcharge
         upon notice thereof; provided, however, that Customer
         shall not be required to reimburse SBC Telco for any

         due solely as a result of a negligent act or omission
         of SBC Telco.

         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),

         and subject to that jurisdiction's regulations.

         (consecutive 12 months) minimum purchase of services shall be based on

         services. This comparison will be made ninety (90) days after

                  billing standards. Prior to sending messages

                  have concerning Unauthorized Messages
                  involving Customer. The provision of such
                  information will not subject SBC Telco to
                  any liability of claim by either the
                  Customer or anyone claiming to be a third
                  party beneficiary of this Agreement. The

                  D upon sixty (60) days advance written
                  notice to the Customer and without
                  Customer's consent. Customers who exceed the
                  pre-determined thresholds, as defined by SBC

Billed Taxes is the amount of taxes billed to End Users for Customer charges since the last settlement. Timely and accurate remittance of taxes to the taxing agency is the responsibility of the Customer.

Surcharges is the total of applicable surcharges collected on the Customer's behalf by SBC Telco. Timely and accurate remittance of surcharges to the reporting agency is the responsibility of the Customer.

Rebills represent the value of messages that have been adjusted from an End User account and processed to be billed to the same or another End User.

Returns (Unbillables) represent the value of messages that have been rejected for billing by SBC Telco and returned to the Customer.

Recourse Adjustments are the amounts debited or credited each settlement period to the Total Current Billable Amount. Recourse adjustments include SBC Telco and Customer initiated End User Adjustments, and Uncollectible Adjustments, defined as follows:

- End User Adjustments are the billed amounts, which SBC Telco removes from End User balance due, in accordance with this agreement.

- Uncollectible adjustments are the amount of non-deniable revenues adjusted through SBC Telco's uncollectible system on final accounts at time of write-off.

Uncollectible Bad Debt Allowance is an amount deducted from Total Current Billable Amount adjusted for Billed Taxes and Recourse Adjustments to compensate for losses resulting from failure of End Users to pay Final Customer Bill amounts due. Derivation of the Uncollectible Bad Debt Allowance is defined in Section 1.1.3.

Customer messages lost by SBC Telco will be estimated by SBC Telco based upon procedures defined in this

Agreement and, if not previously calculated in the 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
Section 1.1.4.

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

Amount Due SBC Telco equals all charges due or to become due to SBC Telco under this Agreement and any applicable tariff.

Net Purchase of Accounts Receivable amount is the Amount due the Customer less the Amount Due SBC Telco.

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 factor as determined below:

1.1.3.1. New Customers

Until valid uncollectible data can be accumulated by SBC Telco on the Customer, normally 6 (six) to 9
(nine) months of realized uncollectible monthly activity, the Customer's uncollectible factor will be set at 25% for the first two months, defined as the Customer submitting billings to SBC Telco no less eight consecutive weeks over a two calendar month time frame. After the first two months of billings as defined above, the factor will set to an industry average for like billings or another surrogate factor acceptable to SBC Telco, and will be applied to the Customer's account receivables; provided however, the

two month reserve will in no event be less than 50% of the largest one month's billing submitted to SBC 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 amounts.

1.1.3.6. The most recent uncollectible bad debt allowance factor will be used by SBC Telco until a revised uncollectible

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

- Prior quarter's reserve amount held by SBC Telco


= +/- True-up amount

A positive true-up amount will be due SBC Telco and a 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 the month following the close of the quarterly period. The true-up settlement will be included in the calculation of the Amount Due the Customer.

1.1.4.4. If the actual net bad debt realized is greater than 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 billing services offered under this Agreement.

1.1.4.5. A final true-up will be performed on 9 -12 months of data following the termination of billing and collections Bill Rendering services. The formula for the final true-up is:

All realized uncollectibles not previously tuned-up

- All discounted uncollectibles not previously trued-up

- Current reserve held by SBC Telco


= Final true-up amount

A positive true-up amount will be due SBC Telco and a negative true-up amount will be due the Customer.

1.1.4.6. The final true-up will be calculated by the end of the 9* to

12th month following termination of billing and collections Bill Rendering services. The true-up settlement will be made within 90 days thereafter.

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

+        The amount of adjustments
         experienced in the prior three
         months of billings with respect to
         live accounts. Current reserve held
         by SBC Telco

+        The amount of revenues adjusted in
         the prior three months through SBC
         Telco's uncollectible system on
         final accounts at write-off

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

=        Required Reserve Amount

The required reserve amount for Customers not subject to procedures defined in 1.1.5.1 and 1.1.5.2 above will be established and maintained by SBC Telco as a current reserve and will be determined by calculating the total realized uncollectibles for the current quarterly period x (multiplied) .667.

1.1.5.3. (Pacific Bell and Nevada Bell only) In addition to the Customer's reserve requirement defined above, the Customer's minimum annual purchase of service requirements will be reviewed on a quarterly basis and

any prorated short fall will be maintained
in the reserve requirement based on the
following calculation:

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

- All annual billing and collection charges


= Required Reserve Amount

A positive amount will be calculated into
the Customer's reserve requirement. A
negative amount will not require a reserve
requirement for the minimum annual purchase
of service.

1.1.5.4. Notwithstanding the above, SBC Telco at its sole discretion reserves the right to increase the reserve amount, if the Customer's uncollectibles, adjustments, minimum annual purchase of service (Pacific Bell and Nevada Bell), 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 SBC Telco shall deem necessary to cover the risk involved or require the Customer to fund the increased reserve amount.

1.1.5.5. Deposits and Reserves

In the event the Customer has not established credit with SBC Telco or has information services billings that are 25% or greater of its projected or actual total billed revenue, or has repeatedly failed to pay SBC Telco in a timely manner for Billing and Collection Services provided by SBC Telco under previous billing agreements, or fail to pay the charges for the services provided under this Agreement in a timely manner, SBC Telco shall have the right to require a deposit from the Customer to guarantee payment. The deposit shall be the actual or estimated charges for services, including amounts for anticipated Adjustments and uncollectibles, for providing the Service to the Customer for a four month period. The anticipated Adjustments and

                  uncollectibles shall be based on the greater
                  of the Customer's historical Adjustment and
                  uncollectible for the Customer's type of
                  telecommunications services. SBC Telco
                  reserves the right to increase the deposit
                  in the event the Customer's billing volumes
                  increase to the extent that the existing
                  deposit no longer represents the actual
                  charges for services, over a four month
                  period. Upon termination of the service, SBC
                  Telco shall credit the amount of the deposit
                  to the Customer's account and any remaining
                  credit balance will be refunded or credited
                  to the Customer's account prior to
                  termination of the Service if the Customer
                  has promptly paid all relevant charges for a
                  period of one year.

Interest on the settlement amount shall be calculated as follows:

- If the claim is received within six
(6) months of the disputed charge(s), the interest will be calculated according to the late payment charge factor described in Paragraphs 1.1.10 or 1.2.7 from the date of the disputed payment amount.

- If the claim is received after six
(6) months of the disputed charge(s), the interest will be calculated from receipt of the claim notification according to the late payment charge factor described in Paragraph 1.1.10 or
1.2.7. After written notice to the paying Party that the claim has been sustained, the total amount due, with interest, to the remittance date or as otherwise agreed to by the Parties, shall be remitted no later than 30 calendar days following resolution.

         4.1.1    Formula for Calculation of the Net Purchase/Collected
                  Amount Due Customer

                  The Ameritech Operating Company (AOC) will use the
                  following formula for the calculation of the Net
                  Purchase/Collected Amount Due Customer for the

Purchase/Collection of Accounts Receivable:

Total Revenue Accepted

+ Total Billed Taxes/Surcharges (AOC-generated)

+/- Recoursed Adjustments, Duplicates, Unbillables and Rebills

- Anticipated Uncollectibles

+/- Uncollectible Settlement True-Up

+/- Reserve for Recoursed Adjustments

- Gross Receipts Tax (if applicable)

= Net Purchased/Collected Amount Due Customer

A. Total Revenue Accepted

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 Statement(s) will include all revenues accepted from the transmissions for a specific journal month.

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

CINGULAR WIRELESS LLC

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

32

CINGULAR WIRELESS LLC

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

EXHIBIT 10.62

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

33

CINGULAR WIRELESS LLC

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

EXHIBIT 10.62

Exhibit B
Ameritech

user accounts written off during the
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 follows:

  Months of Study       Months Factor Applied
----------------------------------------------
 OCT     NOV   DEC      JAN     FEB      MAR
----------------------------------------------
 JAN     FEB   MAR      APR     MAY      JUN
----------------------------------------------
 APR     MAY   JUN      JUL     AUG      SEP
----------------------------------------------
 JUL     AUG   SEP      OCT     NOV      DEC
----------------------------------------------

E. Uncollectible Settlement True-Up

The AOC will true-up the difference between the amount of Anticipated Uncollectibles (Allowance for Uncollectibles) withheld and the amount of Realized Uncollectibles which actually resulted. The difference will be the Uncollectible Settlement True-Up. If the Realized Uncollectibles exceed the Anticipated Uncollectibles, the difference will be deducted from the Amount Due to 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

34

CINGULAR WIRELESS LLC

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

EXHIBIT 10.62

Exhibit B
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.

F. Reserve Requirement

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 uncollectibles adjustments and/or billed (accepted) revenues fluctuate to an extent as to appear unstable or insufficient to

35

CINGULAR WIRELESS LLC

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

EXHIBIT 10.62

Exhibit B
Ameritech

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 .667

+ The amount of adjustments experienced in the prior three months of billings with respect to live accounts

= Required Reserve Amount

3. The required reserve amount for Customers not subject to procedures 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 .667.

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

EXHIBIT 10.62

Exhibit B
Ameritech

= + Reserve True-Up Amount

A positive true-up amount will be due AOC and a negative true-up amount will be due the Customer.

AOC may continue to hold the Reserve amount through the Final True-Up Upon Cessation of Billing and Collection Services.

         G.       Gross Receipts Tax

                  Income from Accounts Receivable may be subject to a
                  State Gross Receipts Tax. If applicable, the Customer
                  will compensate the AOC for this additional tax
                  liability including a gross-up designed to offset the
                  additional tax liability caused by the reimbursement.
                  The AOC will calculate the Gross Receipts Tax amount
                  each bill month and subtract it in the calculation of
                  the Net Purchase/Collected Amount Due the Customer.

4.1.2    Final True-Up Upon Cessation of Billing and Collection
         Services

         For a period of one year after the AOC ceases to provide
         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
                  the State in which the AOC provides Billing and
                  Collection Services to the Customer, or

         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)
         calendar days prior to that date, in which case the due date
         shall be twenty (20) calendar days after the Customer's
         receipt of the bill. It is the Customer's responsibility to
         substantiate that a bill was received after the specified time
         frame. If the Payment Date would cause

         payment to be due on a Saturday, Sunday, or AOC/Customer/bank
         Holiday, payment for the Amount Due the AOC will be 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.

4.2.3    Payment Method

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

4.2.4    Payment Detail

         Any payment to the AOC from the Customer must identify the AOC
         invoice being paid.

4.2.5    Netting of Amount Due AOC

         4.2.5.1. AOC reserves the right to net against the Customer
                  accounts receivable purchases all Billing and
                  Collection Services which AOC has not received
                  payment on or prior to the Payment Date of the
                  statement detailing the amount due AOC.

         4.2.5.2. Furthermore, AOC 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 AOC has not received payment
                  on or prior to the Payment Date of the statement
                  detailing the amount due AOC. These non-Billing and
                  Collection Service charges

can include, but are not limited to, Account Maintenance, Billing Name and Address, Mechanized Data Gathering, Customer Name and Address, Customer Name and Location, and On-Line Inquiry.

4.2.5.3. AOC may, at its sole discretion, process all future Purchase of Accounts Receivable under netting. AOC will apply any late payment penalty incurred by the Customer. AOC will notify the Customer if such netting is required.

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

4.2.6    Late Payment Penalty

         Any payment received by the AOC after the Payment Date, or any
         payment received in funds which are not immediately available
         to the AOC on the Payment Date, will be subject to a Late
         Payment Penalty. The Late Payment Penalty shall be the portion
         of the Amount Due the AOC (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 AOC. The late 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
                  the State in which the AOC provides Billing and
                  Collection Services to the Customer, or

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

4.2.7    Late Payment Resulting from Bank Error

         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.

4.3.1    Notification of Disputed Amount

         Either Party may dispute any portion of the Amount Due (as
         defined in Paragraphs 4.1.1 and 4.2.1). Said Party shall
         notify the other Party in writing of the nature and basis of
         the dispute. The claim period shall be limited to six (6)
         months from the issuance by AOC of the statement of Amount
         Due.

4.3.2    Payment of Disputed Amount

         Should the dispute not be resolved by the Payment Date, the
         payer shall, notwithstanding the continuing existence of the
         dispute, pay the billed amount in accordance with settlement
         terms defined in Subsections 4.1 and 4.2, but said Party shall
         reserve and have claim against the other Party for
         reimbursement if the dispute is resolved at a later date in

4.3.3    Ultimate Settlement of Disputed Amount

         The Party receiving the notice of dispute shall have 30
         calendar days from the notification date, or other mutually

         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
         be calculated and remitted as follows:

         A.       Interest will be calculated according to the late
                  factor described in Paragraphs 4.1.7 or 4.2.6 and
                  will include the period from the date such
                  overpayment/underpayment was made available to the
                  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
         reasonably be required for resolution of the disputed amount
         during the tendency of the dispute.

SECTION 5.0 IS APPLICABLE ONLY TO SOUTHERN NEW ENGLAND TELEPHONE.)

5.0 SETTLEMENT TERMS

5.1. Amount Due Customer

Accounts Receivable - Southern New England Telephone (SNET) will purchase accounts receivable for messages billed to Customer end user accounts billed under this Agreement in accordance with the provisions of this Section 5.

5.1.1. Formula for Calculation of Amount Due Customer

SNET will use the following formula for calculation of the dollar amount due Customer for the purchase of accounts receivable prior to netting of the Billing Services Charges:

Amount of Rated Messages Received

+/- Recourse Adjustments

- Uncollectible Bad Debt Allowance

+/- Quarterly Uncollectible True-up Amount

- Unbillables

+ Federal Excise Tax (if Customer to remit directly)

+ Connecticut State Sales Tax (Customer required to remit)


= Amount Due Customer

Where:

A. Amount of Rated Messages Received is the amount of the messages received by SNET from Customer for billing.

B. Recourse Adjustments are the amounts debited or credited for end user adjustments in accordance with SNET' Inquiry Procedures, plus any Customer initiated adjustments.

EXHIBIT 10.62

Exhibit B
SNET

C. Uncollectible Bad Debt Allowance is an amount deducted on the Purchase of Accounts 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.

E. Factor Development

The following table reflects the months used in the uncollectible bad debt factor development and months to which such factor shall apply.

Uncollectible  Total Amount Billed
   Realized     (Net Adjustments)     Factor Applied

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 shall not be reduced to ten percent (10%) until the calculated uncollectible factor is less than or equal to ten percent (10%) for three consecutive months.

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 related charges and/or Customer's Net 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.

5.1.5.1  The date and revenue value of all Casual
         Billing transmissions (accepted messages)
         will be tracked by SNET from the first
         through the last day of each calendar month.
         The revenue value of Casual Billing
         transmissions received on each day of the
         month will be multiplied by the day (date)
         of the month that the transmission is
         received, plus one (1), to determine a
         weighted revenue value for all
         transmissions. At the end of each calendar
         month, the weighted revenue value of all
         Casual Billing transmissions for the month
         will be divided by the actual revenue value
         of all Casual Billing transmissions for the
         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.

5.2.2. Netting Process

SNET shall deduct the amount due SNET from Customer as calculated in Section 5.2.1. above from the amount due Customer from SNET as described in Section 5.1. of this Exhibit.

Furthermore, SNET has the right to net outstanding non-Billing and Collection Service charges, either displayed 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 SNET has not received payment on or prior to the Payment Date of the statement detailing the amount due SNET. These non-Billing and Collection Service charges can include, but are not limited to, Account Maintenance, Billing Name and Address, Mechanized Data Gathering, Customer Name and Address, Customer Name and Location, and On-Line Inquiry.

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.

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:

Bills Rendered Per Month                         Complaint Percentage
------------------------                         --------------------
80,000 bills rendered or less                             0.5%
80,001 - 300,000 bills rendered                           0.2%
300,001 + bills rendered                                  0.1%

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.

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.

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.

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,
Section II) -- that which is proprietary to the Customer and will not be used by the SBC Telcos, except as necessary for the SBC Telcos to perform its obligations under this Agreement or as may otherwise be consented to in writing by the Customer.

3.0 HANDLING OF PROPRIETARY INFORMATION

Except for information not subject to the terms and conditions herein because of its prior disclosure of permitted or consented disclosure as described below, Proprietary Information of one Party ("Disclosing Party") that is possessed by the other Party ("Receiving Party"), shall be treated in accordance with the following terms and conditions:

A. The Receiving Party shall put in place and strictly enforce (using all of its prerogatives, including appropriate 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:
