EXHIBIT 10.20



| | B. |  | In the event of technology driven changes that improve the functionality of a Service to a material extent or a new service type (NEW) is offered, and
such functionality or new service is required by Customer, Customer may request in writing, that Sprint make such functionality, or a substantially equivalent functionality, available to Customer. In such event, Customer and Sprint agree to
negotiate, in good faith, the terms and conditions of an agreement (the NEW Agreement). This NEW agreement would govern the migration of Customers usage of services pursuant to this Agreement to a Sprint-provided new service plan,
in which case Sprint agrees to negotiate with Customer to reach a mutually agreeable position for the MAC. Should a new service become commercially available from another Tier One Telecommunications Carrier and Sprint be unable to provide new
service to Customer within six (6) months following receipt of Customers request for new service pursuant to this subsection and Customer purchases such new services from another carrier, then Sprint agrees to negotiate with Customer to reach
a mutually agreeable position on the MAC, following the expiration of the six (6) month period.
| | -- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. |  | If Sprint becomes the subject of a bankruptcy, insolvency, administration, reorganization or liquidation proceeding, or any other similar or related company
reconstruction, receivership or administration action, whether voluntary or involuntary; and materially fails to provide Services as outlined in this Agreement, Customer may terminate the affected service element. To terminate for such failure,
Customer must give Sprint written notice of the failure and provide Sprint a reasonable opportunity to cure, which will be a minimum of 30 days from Sprints receipt of notice. If Sprint fails to cure, then Customer may terminate the effected
service element 30 days after giving Sprint written notice of termination due to the material failure. Sprints material failure does not include a failure caused by circumstances not within Sprints sole control, including, but not
limited to, a failure caused by: (a) a local exchange carrier; (b) Customer-provided equipment; or (c) Customer. Notwithstanding termination of the effected element as set forth in this Section, Customer will remain liable for all invoices, charges
and fees that remain outstanding, whether or not invoiced by the termination date.

| | D. |  | One time after the 18thbilling
month and/or the Customers Monthly Volume of Services (MVS) has equaled or exceeded $3,000,000 annually for the immediately preceding 12 billing month cycle, Sprint will, upon Customers written request, review the status of
Customers rates for services priced in this agreement to determine if Customer is eligible to receive a rate adjustment for Services. Any revision may depend on Customers agreement to adjust this Agreements Term or MSC. To qualify
for this review, Customer must be in compliance with all Agreement terms and conditions, including its MSC and any Preferred Interexchange Carrier requirements.

Conditions) for Domestic Sprint Dedicated IP.
| |  |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



(1.) For any termination request occurring in the 1st year of the order term, Customer will notify Sprint in writing 6 months prior to termination and Customer will be liable for (a.) 15% of the MRC multiplied by the number
of months remaining in the initial term. Customer will be liable for any and all DS3 and greater bandwidth Access Termination Costs Sprint incurs from a Local Exchange Carrier.



(2.) For any termination request occurring in the 2nd year of the order term, Customer will pay (a.) 15% of
the MRC multiplied by the number of months remaining in the initial term. Customer will be liable for any and all DS3 and greater bandwidth Access Termination Costs Sprint incurs from a Local Exchange Carrier.

| | a. |  | All ingress and egress traffic will be measured and summed over a 24-hour period. This sum is then divided by the theoretical maximum throughput available during
that period. The resulting average is termed the daily port utilization value.
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b. |  | All of the daily port utilization values for the billing period are ranked from highest to lowest, and the top 5% are discarded.
