1. Application of NTT America Backbone SLA

These NTT America ("NTT America") Backbone Service Level Agreements (SLAs) provide Customers in North America with certain rights and remedies regarding the performance of the NTT America Backbone (as defined below). These NTT America Backbone SLAs apply only to North American Customers receiving the following services from NTT America: (i) T1, T3, OC3, OC12, OC48 or Ethernet services, and/or (ii) colocation or dedicated server services utilizing the NTT America Backbone (each a "Customer"), unless otherwise specified for a Customer.

2. Definitions

For purposes of these NTT America Backbone SLAs, the following terms have the meanings set forth below:

• "NTT America Backbone" means NTT America owned and operated Internet Protocol (IP) routing infrastructure consisting solely of selected NTT America points of presence at which NTT America has installed measurement devices ("Selected POPs") (i) within the United States and the connections between them in the forty-eight continental United States (the "North American Network"), (ii) within Europe and the United States and the Trans-Atlantic connections between such Selected POPs (the "Trans-Atlantic Network") and (iii) within Asia and the United States and the Trans-Pacific connections between such Selected POPs (the "Trans-Pacific Network").
• "Network Outage" means an instance in which no traffic can pass in or out of the Selected POP through which Customer connects to the NTT America Backbone for more than 15 consecutive minutes.
• "Latency" means the average time required for round-trip packet transfers between Selected POPs on the selected portions of the NTT America Backbone during a calendar month, as measured by NTT America.
• "Packet Loss" means the average percentage of IP packets transmitted between Selected POPs during a calendar month that are not successfully delivered, as measured by NTT America.
• "Average Jitter" means the average variation in delay for packet transfers between Selected POPs during a calendar month, as measured by NTT America.
• "Maximum Jitter" means the maximum variation in delay for packet transfers between Selected POPs, as measured by NTT America.
• "Base Fee" consists solely of the base monthly fee paid by Customer for the affected NTT America service and excludes all other fees which might be charged to Customer, including, by way of example and not limitation, set-up fees, fees for local loop, space rental fees, charges for additional services such as managed services, incremental bandwidth usage, electricity, extra IP addresses, RAM, or hard drives beyond that which is available without additional charge under NTT America's standard rates, hourly support charges, and other types of optional additional services.

For example, for Dedicated Server Customers, the Base Fee may include just the fee for the standard server package, which would cover the use of the server and up to the amount of data transfer allowed each month without additional charge. For Customers of other NTT America services, the Base Fee may include just the base monthly access or bandwidth fee paid by a Customer.

3. Summary of NTT America Backbone SLAs

As described in more detail below, these NTT America Backbone SLAs provide commitments based upon goals in four key areas:

• The NTT America Backbone available to Customer free of Network Outages 100% of the time.
• Latency of the NTT America Backbone of (i) 50 milliseconds or less for the North American Network, (ii) 90 milliseconds or less for the Trans-Atlantic Network and (iii) 130 milliseconds or less for the Trans-Pacific Network.
• Packet Loss of the NTT America Backbone of 0.1% or less.
• Average Jitter on the NTT America Backbone of 250 microseconds or less; and Maximum Jitter not to exceed 10 milliseconds more than 0.1% of the time.

4. NTT America Backbone Availability

NTT America's goal is to make the NTT America Backbone available to Customer free of Network Outages 100% of the time.

Subject to Sections 9 and 10 below, upon Customer's request, NTT America will issue a credit to Customer for Network Outages in an amount equal to one day's worth of the Base Fee paid by Customer, multiplied by each hour (or portion thereof rounded to the next hour) of the cumulative duration of such Network Outages during a particular month.

5. NTT America Backbone Latency

NTT America's goal is to keep Latency on the NTT America Backbone to (i) 50 milliseconds or less for the North American Network, (ii) 90 milliseconds or less for the Trans-Atlantic Network and (iii) 130 milliseconds or less for the Trans-Pacific Network.

Subject to Sections 9 and 10 below, if Latency on the North American Network, the Trans-Atlantic Network or the Trans-Pacific Network, as applicable, for a calendar month exceeds the time frame set forth above for the applicable portion of the NTT America Backbone, NTT America will issue a credit to Customer equal to one day's worth of the Base Fee paid by Customer for such month.

The terms of this NTT America Backbone SLA related to Latency will take effect the first full calendar month after Customer's first use of the NTT America Backbone.

6. NTT America Backbone Packet Loss

NTT America's goal is to keep Packet Loss on the NTT America Backbone to 0.1% or less. If Packet Loss on the NTT America Backbone exceeds 0.1% during a calendar month, NTT America will issue a credit to Customer equal to one day's worth of the Base Fee paid by Customer for such month.

The terms of this NTT America Backbone SLA relating to Packet Loss will take effect the first full calendar month after Customer's first use of the NTT America Backbone.

7. NTT America Average and Maximum Jitter

NTT America's goal is to keep Average Jitter on the NTT America Backbone to 250 microseconds or less; and for Maximum Jitter not to exceed 10 milliseconds more than 0.1% of a calendar month. Subject to Sections 9 and 10 below, if Average Jitter on the NTT America Backbone exceeds 250 microseconds; or if Maximum Jitter exceeds 10 milliseconds more than 0.1% of a calendar month, NTT America will issue a credit to Customer equal to one day's worth of the Base Fee paid by Customer for such month.

The terms of this NTT America Backbone SLA relating to Jitter will take effect the first full calendar month after Customer's first use of the NTT America Backbone.

8. Measurement

NTT America will periodically (on average every 5 minutes) measure the NTT America Backbone at Selected POPs using software and hardware components capable of measuring traffic and responses at such Selected POPs. Customer acknowledges that not every POP may be covered by such measurements, that such measurements may not measure the exact path traversed by Customer's packets, and that such measurements constitute measurements across the NTT America Backbone but not other networks to which Customer may connect. NTT America reserves the right to periodically change the measurement points and methodologies it uses without notice to Customer. For reports of performance of the NTT America Backbone, please refer to the relevant links provided at the Global IP Network SLA.

9. Exceptions

Customer shall not receive any credits under these NTT America Backbone SLAs in connection with any failure or deficiency of the NTT America Backbone caused by or associated with:

10. Credit Request and Payment Procedures

In order to receive a credit under these SLAs, Customer must make a request by accessing and following the credit request procedures set forth at the SLA Credit Request Form. Each request in connection with a Network Outage must be received by NTT America within seven days of the Network Outage and must be confirmed by NTT America's measurements of the NTT America Backbone. NTT America must receive each request in connection with Latency, Packet Loss, Average Jitter or Maximum Jitter in a calendar month within seven days after the end of such month.

Each valid credit will be applied to an invoice of Customer within two billing cycles after NTT America's receipt of Customer's request. Credits are exclusive of any applicable taxes charged to Customer or collected by NTT America.

Notwithstanding anything in this NTT America Backbone SLA to the contrary, the total amount credited to a Customer in connection with Network Outages, Latency, Jitter and Packet Loss in any calendar month will not exceed the Base Fee paid by Customer for such month.
