Common use of Additional Mileage Clause in Contracts

Additional Mileage. Subject to the overall IRU Capacity limitation set forth herein, PSINet, at its option, may order Bandwidth on portions of the Available System in excess of 10,000 Route Miles (the "Excess Miles") provided that: (a) the aggregate Route Mileage covered by Bandwidth Units, regardless of the level or type of Bandwidth which is then being provided by IXC to PSINet thereon, does not exceed 15,000 Route Miles; (b) pursuant to the Collocation Agreement in the form attached hereto as Exhibit C, PSINet will pay the market rate for cabinet space used in connection with the Excess Miles; and (c) PSINet will pay IXC' fees for add/drop, multiplexing and reconfiguration on the Excess Miles, as set forth herein. To the extent PSINet orders Bandwidth on Excess Miles, the parties will in good faith attempt to negotiate and effect adjustments in PSINet's rights in the PSINet Fiber IRU and in the security interest in the Long-Term Indefeasible IRU, with such rights to be expanded to cover such Bandwidth in the Excess Miles and to be reduced so as not to cover PSINet's usage of Bandwidth to the extent less than an OC-48 on any portion of the original 10,000 Route Miles of the Available System.
