Monthly bills will continue to be rendered pursuant to Section 5.2. 5.2.2.1 SUSPENSION OF SERVICE. If full payment for actual usage plus Commitment Shortfall, if any, is not received by AT&T by Wednesday noon in any given week, AT&T shall have the right to suspend Service hereunder that day upon oral or faxed notice to Customer.

Interfacing and -------------------------------------------- communicating with End-users shall be the sole responsibility of Customer with respect to any use that Customer may make of the Service provided pursuant to this Agreement to in turn provide service to other persons or entities.

DEPOSITS. AT&T may require the Customer, prior to or during the provision -------- of Service pursuant to this Agreement, to tender a deposit in an amount to be determined by AT&T in its reasonable discretion to be held by AT&T as a guarantee for the payment of charges. To determine the financial responsibility of Customer and/or the specific amount of any deposit required, AT&T may rely upon commercially reasonable factors to assess and manage the risk of non-payment, including but not limited to payment history for telecommunications service (including such service purchased from AT&T), number of years in business, bankruptcy or insolvency history, current AT&T account treatment status, financial statement analysis, and commercial credit bureau rating. It shall be Customer's responsibility to provide to AT&T upon request such information as is necessary for AT&T to determine the financial responsibility of Customer, including but not limited to Customer's tax returns, audited or unaudited financial statements and loan applications. A deposit does not relieve Customer of the responsibility for the prompt payment of bills on presentation or the due date appearing on the face of the bills. In lieu of a cash deposit, AT&T will accept Bank Letters of Credit and Surety Bonds which have been approved by AT&T. Interest will be paid to Customer for the period that a cash deposit is held by AT&T. The interest rate used will be compound interest compounded monthly at the rate of six percent annually unless a different rate has been established by the appropriate legal authority in the state where the Service offering is located. The failure of Customer to post a deposit as required by AT&T pursuant to this paragraph shall constitute a material breach of this Agreement by Customer which shall entitle AT&T to terminate this Agreement and the Service provided hereunder upon five (5) business days written notice to Customer. When the Service for which the deposit has been required is discontinued, the deposit will be applied to the final bill and any credit balance will be refunded to the Customer with applicable interest accrued. 5.6.

In any instance in which AT&T believes in good faith that Service is being used in such manner, AT&T may immediately restrict Service on a temporary basis. In such cases, AT&T will make a reasonable effort to give the Customer prior notice. In the event that Customer does not provide to AT&T within five (5) business days of the temporary restriction of Service acceptable proof that said use has ceased and that appropriate measures have been taken to prevent its recurrence, AT&T may immediately and without further notice terminate Service. 5.7.
