On or before the Bill Due Date, WSP must pay: (i) all undisputed amounts to AT&T-21STATE and (ii) all Disputed Amounts into an interest bearing escrow account with a Third Party escrow agent that is mutually agreed upon by the Parties. 10.10 Identification of circumstances in which the Non-Paying Party shall not be required to pay a Disputed Amount into an escrow account: 10.10.1 The Non-Paying Party shall not be required to pay a Disputed Amount into an escrow account if its total Disputed Amounts not paid into escrow do not exceed $50,000. 10.10.2 The Non-Paying Party shall not be required to pay a Disputed Amount into an escrow account if it has established a minimum of 12 consecutive months of timely payment history and its total outstanding and unpaid invoice charges do not exceed 10 percent of the then current monthly billing to said Non-Paying Party. 10.10.3 If the Billed Party believes in good faith that a billed amount is incorrect by reason of a clerical or arithmetic error (e.g., erroneous use of a $0.50 rate when applicable rate for the service billed is $0.05, or multiplication by 1220 units when actual number of units was 220), the Billed Party may dispute the bill by bringing the asserted error to the Billing Party’s attention without paying the Disputed Amount into an escrow account. Upon the assertion of such a dispute, 10.10.3.1 If the Billing Party agrees in all respects with the Billed Party’s assertion of the error, the Billing Party will correct the error. 10.10.3.2 If the Billing Party agrees that a billing error has apparently occurred, but requires additional time for investigation or to ascertain the correct amount, the Billing Party will notify the Disputing Party in writing of the portion of its invoice, if any, that the Disputing Party is required to pay or escrow pending resolution of the dispute, with the amount of any required escrow to be reasonable under the circumstances. The Non-Paying Party shall pay into escrow as set forth in Section 10.12 below the amount reasonably specified by the Billing Party within five Business Days of its receipt of such specification, and if (but only if) the Non-Paying Party does so, the payment into escrow will be deemed to have been made for purposes of perfection of the dispute, on the date on which the Billed Party initially disputed the bill under subsection 10.10.3. 10.11 If the Billing Party determines in good faith that no billing error has occurred, the Billing Party will so notify the Non- Paying Party, and may demand that the Non-Paying Party pay the Disputed Amount into escrow if it wishes to dispute the bill. Within five Business Days of its receipt of such a demand, the Disputing Party shall pay the Disputed Amount into an interest bearing escrow account as set forth in Section 10.12 below, and if (but only if) the Disputing Party does so, the payment into escrow will be deemed to have been made, for purposes of perfection of the billing dispute, as of the date on which the Billed Party initially disputed the bill under subsection 10.10.3.
