2.1.1.Nevada will provide Master File Maintenance services for the Customer messages for those Customer's End Users for which Nevada has Bill Processing service responsibilities. Balance due amounts previously billed by the Customer are not to be included as a message or other related charges to be billed by Nevada. Customer violation of this provision will materially affect the essence of this Agreement and will constitute substantial breach of its terms. Nevada reserves the right to return to the Customer any such messages prior to billing to the End User. In the event that Nevada places any such messages on an End User bill, Nevada reserves the right to adjust the End User bill for such messages. Adjustments will be recoursed to the Customer.

It is the responsibility of the Customer to maintain, and to resupply to Nevada if necessary, for a minimum of ninety (90) days from the date of receipt by Nevada, a back-up file of all rated messages provided to Nevada. This will allow Nevada to reconstruct lost records. If the Customer fails to maintain a back-up file for reprovisioning of messages to Nevada throughout the prescribed time frame, Nevada will not be liable for any such lost records.

In the event the data cannot be recovered by Nevada and the Customer's obligation to resupply the data has expired, Nevada 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: Unless otherwise agreed to by the Customer and Nevada, an industry average price for direct dialed long distance service 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 in Section 3., Settlement Terms.
