Change in Service/Number - Any change in the Service or the Equipment may require additional programming or Equipment or changes to Numbers assigned to Customer. Customer may be assessed a programming fee in connection with any change requested by Customer. Nextel may, at any time, change or remove any Number assigned to Customer when such change is reasonably necessary in the conduct of Nextel’s business. Customer acknowledges that Customer has no proprietary or ownership rights or interest in Customer’s Number(s) and cannot acquire such rights or interest through usage, publication or otherwise. Customer may not assign its Number to any other Equipment and shall not program any other Number into its Equipment.

Upon such request, all amounts then owed to Nextel (including damages for early termination and any amounts that appear on the
