	3.3	If payment is not received by either Party by the Due Date, a late fee of the lesser of (a) one and one-half (1¹/2) percent per month or (b) the maximum percentage permitted by law shall be assessed on Parties delinquent balance of undisputed usage not paid by the Due Date.
	3.4	Each Party's execution of this Agreement signifies its acceptance of the other Party's initial and continuing credit approval procedures and policies. Each Party reserves the right to withhold initiation or full implementation of any or all Services under this Agreement pending its initial satisfactory credit review and approval thereof which may be conditioned upon terms specified by it, including, but not limited to, security for payments due hereunder in the form of a cash deposit or other means. Each Party reserves the right to modify its requirements, if any, with respect to any security or other assurance provided by the other Party for payments due hereunder in light of that other Party's actual usage when compared to projected usage levels upon which any security or assurance requirement was based.

	3.5	If at any time there is a material adverse change in the other Party's creditworthiness, then in addition to any other remedies available to, each Party may elect, in its sole discretion, to exercise one or more of the following remedies: (i) cause start of the Services to be withheld; (ii) cease providing Services pursuant to a suspension notice in accordance with Section 6.2; (iii) decline to accept requests to provide Services which it may otherwise be obligated to accept; and/or (iv) condition its provision of Services on an assurance of payment which shall be a deposit or such other means to establish reasonable assurance of payment.

	3.6	Each Party shall be solely responsible for billing and collection from its own service partners and customers. No payments due hereunder are contingent on payment due to either party from its own service partners or customers. Under no circumstances shall either Party be responsible to the other for fraudulent or unbillable calls, credits given by the other Party, bad debts or other uncollectible amounts incurred by the other Party.
	3.7	Disputes. The Parties shall promptly investigate any disputed charges and any other amount payable under this Agreement in the event of a dispute. If the disputed amount is less than three (3) percent of the total (excluding taxes) of the relevant invoice, the total amount invoiced shall be due and payable on or before the due date. If the amount in dispute is more than three (3) percent of the total (excluding taxes) of the relevant invoice, the disputed amount may be withheld until the dispute is resolved. Disputed amounts less than three (3) percent shall be refunded to the paying Party if the dispute is resolved in its favor. Any request for a billing adjustment must be made in good faith and in writing within thirty (30) days of the invoice date. Invoices shall be deemed accepted where written objections are not lodged within such thirty (30) day period. Notification of any contested or disputed amount must be in writing and delivered in accordance with Section 11.4. Written notification must be accompanied with a detailed written support, for any service interruption credit or other credit to which the Party requesting the billing adjustment believes itself entitled, and both Parties will promptly address and attempt to resolve the claim.

	3.8	The charges specified in this Agreement are exclusive of value added tax ("VAT"), or any other applicable tax, which, if due and owing, shall be added to the invoice and charged to and paid by the Service Partner at the then prevailing rate.
