CENTURYLINK MASTER SERVICE AGREEMENT

This Master Service Agreement (“Agreement”) is between CENTURYLINK COMMUNICATIONS, LLC (“CenturyLink”) and PRECISION OPINION (“Customer”) and is effective on the date the last party signs it (the “Effective Date”). This Agreement provides the terms and conditions applicable to Customer’s purchase of products and services (“Service”) from CenturyLink.

1. Term; Commitment. The term of the Agreement will commence on the Effective Date and continue until the expiration of the last Service term, unless earlier terminated in accordance with the Agreement (“Term”). The Revenue Commitment for the Agreement is set forth on the following Addendum attached and incorporated into the Agreement.

2. Service. CenturyLink will provide Service in accordance with the Agreement, including all applicable Service Schedules, Service Exhibits, Statements of Work, Order(s), pricing attachments, and any other documents that are attached or expressly incorporated into the Agreement (“Service Attachments”). The following Service Attachments are initially attached and incorporated into the Agreement. At CenturyLink’s discretion, additional Service Attachments may be added by Amendment or by Customer placing an Order.

3. Order(s). Customer may submit requests for Service in a form designated by CenturyLink (“Order”). The term for a Service is defined in the applicable Service Attachment (“Service Term”). Unless otherwise set forth in a Service Attachment, Service will continue month-to-month at the expiration of the Service Term at CenturyLink’s then current rates. CenturyLink will notify Customer of acceptance of requested Service in the Order by delivering (in writing or electronically) the date by which CenturyLink will install Service (the “Customer Commit Date”), by delivering the Service, or by the manner described in a Service Attachment. Renewal Orders will be accepted by CenturyLink’s continuation of Service. For moves, adds or changes agreed to by CenturyLink, Customer will pay CenturyLink’s then current charges unless otherwise specifically stated in a Service Attachment.

4. Billing and Payment.

4.1 Commencement of Billing. Unless otherwise set forth in a Service Attachment, CenturyLink will deliver written or electronic notice (a “Connection Notice”) to Customer when Service is installed, at which time billing will commence (“Service Commencement Date”). If Customer notifies CenturyLink within three days after delivery of the Connection Notice that Service is not functioning properly, CenturyLink will correct any deficiencies and, upon Customer’s request, credit Customer’s account in the amount of 1/30 of the applicable monthly recurring charge (MRC) for each day the Service did not function properly. If CenturyLink cannot complete installation due to Customer delay or inaction, CenturyLink may begin charging Customer for the Service, and Customer will pay such charges.

4.2 Payment of Invoices and Disputes. Invoices are delivered or made available monthly and due 30 days after the invoice date. Fixed charges are billed in advance and usage-based charges are billed in arrears. Customer’s payments to CenturyLink must be made via an ACH transfer or any CenturyLink approved payment portal (e.g., CenturyLink Control Center) in the currency stated on the invoice. CenturyLink may charge administrative fees where Customer’s payment and invoice preferences deviate from CenturyLink’s standard practices. Past due amounts bear interest at 1.5% per month or the highest rate allowed by law (whichever is less). CenturyLink may charge Customer reasonable attorneys’ fees and any third-party collection costs CenturyLink incurs in collecting such amounts. Customer is responsible for all charges regarding the Service, even if incurred as the result of unauthorized use. If Customer reasonably disputes an invoice, Customer must pay the undisputed amount and submit written notice of the disputed amount (with details of the nature of the dispute and the Services and invoice(s) disputed). Disputes must be submitted in writing within 90 days from the date of the invoice. If CenturyLink determines in good faith that a disputed charge was billed correctly, Customer must pay such amounts within 10 days after CenturyLink provides notice of such determination. Customer may not offset disputed amounts from one invoice against payments due on the same or another account.

4.3 Taxes and Fees. Excluding taxes based on CenturyLink’s net income, Customer is responsible for all taxes and fees arising in any jurisdiction imposed on or incident to the provision, sale or use of Service. This includes value added, consumption, sales, use, gross receipts, withholding, excise, access, bypass, ad valorem, franchise or other taxes, fees, duties or surcharges (e.g., regulatory and 911 surcharges), whether imposed on CenturyLink or a CenturyLink affiliate, along with similar charges stated in a Service Attachment (collectively “Taxes and Fees”). Some Taxes and Fees, and costs of administering the same, are recovered through imposition of a percentage surcharge(s) on the charges for Service. If Customer is required by law to make any deduction or withholding of withholding Taxes from any payment due hereunder to CenturyLink, then, notwithstanding anything to the contrary in this Agreement, the gross amount payable by Customer will be increased so that, after any such deduction or withholding for such withholding Taxes, the net amount received by CenturyLink will not be less than CenturyLink would have received had no such deduction or withholding been required. Charges for Service are exclusive of Taxes and Fees. Customer may present CenturyLink with an exemption certificate eliminating CenturyLink’s liability to pay certain Taxes and Fees. The exemption will apply prospectively.

CENTURYLINK MASTER SERVICE AGREEMENT

4.4 Credit Approval and Deposits. Customer will provide CenturyLink with credit information as requested. CenturyLink may require Customer to make a deposit as a condition of CenturyLink’s acceptance of any Order or continuation of: (a) usage-based Services; or (b) non-usage based Service where Customer fails to timely pay CenturyLink hereunder or CenturyLink reasonably determines that Customer has had an adverse change in financial condition. Deposits will not exceed two months’ estimated charges for Service and are due upon CenturyLink’s written request. When Service is discontinued, the deposit will be credited to Customer’s account and the balance refunded.

4.5 Regulatory and Legal Changes. If changes in applicable law, regulation, rule or order materially affect delivery of Service, the parties will negotiate appropriate changes to this Agreement. If the parties cannot reach agreement within 30 days after CenturyLink’s notice requesting renegotiation, CenturyLink may, on a prospective basis after such 30-day period, pass any increased delivery costs on to Customer. If CenturyLink does so, Customer may terminate the affected Service on notice to CenturyLink delivered within 30 days of the cost increase taking effect.

4.6 Cancellation and Termination Charges. Unless otherwise set forth in a Service Attachment:

(a) Customer may cancel an Order (or portion thereof) prior to the delivery of a Connection Notice upon written notice to CenturyLink identifying the affected Order and Service. If Customer does so, Customer will pay CenturyLink a cancellation charge equal to the sum of: (1) for “off-net” Service, third party termination charges for the cancelled Service; (2) for “on-net” Service, one month’s monthly recurring charges for the cancelled Service; (3) the non-recurring charges for the cancelled Service; and (4) CenturyLink’s out-of-pocket costs (if any) incurred in constructing facilities necessary for Service delivery.

(b) Customer may terminate a specified Service after the delivery of a Connection Notice upon 30 days’ written notice to CenturyLink. If Customer does so, or if Service is terminated by CenturyLink as the result of Customer’s default, Customer will pay CenturyLink a termination charge equal to the sum of: (1) all unpaid amounts for Service actually provided; (2) 100% of the remaining monthly recurring charges for months 1-12 of the Service Term; (3) 50% of the remaining monthly recurring charges for month 13 through the end of the Service Term; and (4) if not recovered by the foregoing, any termination liability payable to third parties resulting from the termination and any out-of-pocket costs of construction to the extent such construction was undertaken to provide Service hereunder. The charges in this Section represent CenturyLink’s reasonable liquidated damages and are not a penalty.

5. Default. If (a) Customer fails to make any payment when due and such failure continues for five business days after CenturyLink’s written notice, or (b) either party fails to observe or perform any other material term of this Agreement and such failure continues for 30 days after the other party’s written notice, then the non-defaulting party may: (i) terminate this Agreement and/or any Order, in whole or in part, and/or (ii) subject to Sections 6.1 (Damages Limitations) and 6.3 (Service Levels), pursue any remedies it may have at law or in equity.

The request for credit must be made within 60 days after the end of the month in which the event occurred. Total monthly credits will not exceed the charges for the affected Service for that month. Customer’s sole remedies for any nonperformance, outages, failures to deliver or defects in Service are contained in the Service Levels applicable to the affected Service.

6.4 Right of Termination for Installation Delay. Unless otherwise set forth in a Service Attachment, in lieu of installation Service Level credits, if CenturyLink’s installation of Service is delayed by more than 30 business days beyond the Customer Commit Date, Customer may terminate the affected Service without liability upon written notice to CenturyLink, provided such written notice is delivered prior to CenturyLink delivering a Connection Notice for the affected Service. This Section will not apply where CenturyLink is constructing facilities to a new location not previously served by CenturyLink.

This includes configuration and management of complex routing, switching, device NIC cards, firewall module configurations, and basic router internal firewall functions. CenturyLink acts as the Customer’s single point of contact in managing the resolution of all service, device, and transport faults covered by Comprehensive Management and will work with any third party hardware and/or transport providers the Customer has under contract until all network issues are successfully resolved. With Internet security protocol (“IPSec”), CenturyLink can configure full mesh, partial mesh, or hub-and-spoke topologies with secure tunnels for remote communication between Customer locations. IPSec is only available on approved Cisco and Adtran devices. IPSec opportunities greater than 25 devices or with other manufacturer’s devices require CenturyLink approval before submitting an order.

(d) CenturyLink Responsibilities. For NMS, CenturyLink will provide Customer with a nonexclusive service engineer team, which will maintain a Customer profile for the portion of the Customer’s network where the devices covered by NMS reside. CenturyLink will work with Customer to facilitate resolution of service affecting issues with Select Management or Comprehensive Management.

(e) Customer Responsibilities.

(i) Customer must provide all information and perform all actions reasonably requested by CenturyLink in order to facilitate installation of NMS. If Customer limits or restricts CenturyLink’s read/write access to a device, CenturyLink cannot support configuration backups. Customer is responsible for supporting CenturyLink in access, troubleshooting, and configuration requests made in accordance with normal troubleshooting and repair support activities. For Out-of-Band management related to fault isolation/resolution, Customer will provide and maintain a POTS line for each managed device. “Out-of-Band” means a connection between two devices that relies on a non-standard network connection, such as an analog dial modem, which must be a CenturyLink certified 56k external modem. Additionally, Customer will provide a dedicated modem for each managed device. It is not mandatory that Customer have a POTS line but Customer must understand that CenturyLink will not be able to troubleshoot issues if the device covered by NMS cannot be reached. Service related outages requiring access to the device for troubleshooting and repair purposes will impact the eligibility of any associated SLA credits.

(ii) For Comprehensive Management, Customer must execute the attached Letter of Agency (Attachment 1) to authorize CenturyLink to act as Customer’s agent solely for the purpose of accessing Customer’s transport services.

(iii) Depending on transport type, Customer’s managed devices must comply with the following set of access requirements: (A) for NMS delivered via IP connectivity with an Internet Port or other public Internet service, devices must contain an appropriate version of OS capable of establishing IPsec VPNs; and (B) for NMS delivered with a Private Port, CenturyLink will configure a virtual circuit to access Customer’s device at no additional charge. CenturyLink will add the NMS network operations center to the Customer closed user group to manage the devices within Customer’s network.

(iv) Customer must provide a routable valid IP address to establish the NMS connection. Customer’s primary technical interface person must be available during the remote installation process to facilitate installation of NMS. All Customer devices managed under NMS must be maintained under a contract from a CenturyLink approved onsite CPE maintenance provider. The response times for which Customer contracts with its CPE maintenance provider will affect CenturyLink’s timing for resolution of problems involving Customer provided devices. The performance of the CPE maintenance provider is Customer’s responsibility.

(v) Customer may not reverse engineer, decompile, disassemble or apply any other process or procedure to alter any CPE, software, or other component of this Service for any purpose.

2.4 End-to-End Performance Reporting. End-to-End Performance Reporting is a feature included all Ports, except for Ports with VPLS. Customer must include CenturyLink as a member of each closed user group. The feature includes a report based on data collected from Customer’s traffic within its closed user groups and measures availability, jitter, latency, and packet delivery between Customer’s edge routers, between CenturyLink’s routers, and between Customer’s edge routers and CenturyLink’s routers. The data contained in the report is measured differently than the goals contained in the SLA applicable to the Service and is for informational purposes only. Customer is not entitled to SLA credits based on the data in the report. Customer may access the report in the Control Center portal. Some quote forms or other associated documents may use “End-to-End Performance Monitoring” to mean “End-to-End Performance Reporting”.

2.5 Multicast. Multicast is an optional feature for Private Ports. The feature enables IP multicast on the CenturyLink IP network. Customer must configure its edge devices with CenturyLink designated multicast protocol specifications and use the CenturyLink designated IP address range for Customer’s multicast applications. The standard feature allows up to ten sources of multicast traffic per Customer, but CenturyLink may permit a limited number of additional sources.

2.6 VPLS. Layer 2 virtual private LAN service (“VPLS”) is optional feature for Private Ports only. VPLS is not available for CenturyLink IQ+ Ports or CenturyLink IQ+ Cloud Ports.

CENTURYLINK MASTER SERVICE AGREEMENT

DOMESTIC CENTURYLINK IQ^® NETWORKING SERVICE EXHIBIT

2.7 VPN Extensions. A VPN Extension is an optional feature for layer 3 multi protocol label switching (“MPLS”) Private Ports. The feature allows Customer to extend its Layer 3 MPLS closed user groups to Customer locations that are not served by CenturyLink’s MPLS network (“Remote Location”). Customer can establish a tunnel through the Internet between the Customer’s CPE at the Remote Location (separately purchased and managed by Customer) and the CenturyLink network device. The Customer provided CPE must support the CenturyLink service configurations and be installed as designated by CenturyLink or as otherwise agreed upon by the parties. Customer is responsible for the installation, operation, maintenance, use and compatibility of the Remote Location CPE. Customer will cooperate with CenturyLink in setting the initial configuration for the Remote Location CPE interface with the VPN Extension Service. Customer must use IP connectivity at the Remote Location that includes a static public IP address.

(a) Exclusions. CenturyLink will not debug problems on, or configure any internal or external hosts or networks (e.g., routers, DNS servers, mail servers, www servers, and FTP servers). All communication regarding the VPN Extension must be between CenturyLink and a Customer approved site contact that has relevant experience and expertise in Customer’s network operations. The following features are not available with VPN Extensions: (i) End-to-End Performance Reporting; (ii) QoS; (iii) VPLS; and (iv) Multicast. VPN Extensions are not subject to the SLA.

2.8 Backbone Prioritization/Priority Queuing. Backbone Prioritization and Priority Queuing is an optional feature available with individual domestic Private Ports, CenturyLink IQ+ Ports, and CenturyLink IQ+ Cloud Ports. When this feature is configured on such Port, traffic originating from that Port will be designated at a higher class of service to the CenturyLink IP network than traffic originating from such Ports without the feature or Internet Ports. If Customer desires the feature for traffic between two or more such Ports, the feature must be ordered for each such Port. The benefit from this feature is realized during periods of high network congestion. The feature may not be available at all locations or with Multicast in certain circumstances.

3. Ordering. For purposes of this Service Exhibit, “Order Form” means an electronic order confirmation process using an architecture confirmation document (“ACD”) or other document that Customer and CenturyLink mutually agree to prior to submitting a Service order request. CenturyLink must approve each Order Form and Customer must send it via e-mail, fax, or other CenturyLink-approved electronic process to CenturyLink. Subject to availability, CenturyLink will assign /29 Internet address space for Customer during the use of a Port. Neither Customer nor any End Users will own or route these addresses. Upon termination of Service, Customer’s access to the IP addresses will cease. If Customer requests special sequencing for Port installation, Customer must designate a Key Port. A “Key Port” is a Port that must be available on the network before adding additional domestic Port locations. The installation of the Key Port will determine the timelines for the installation of other domestic Ports. Customer may designate one Key Port within its CenturyLink IQ Networking network topology by notifying CenturyLink in writing of that request. Unless the parties otherwise agree in writing, Customer has sole responsibility for ordering, securing installation and ensuring proper operation of any and all equipment required to enable Customer to receive the Service.

4. Charges. Customer must pay all applicable MRCs and NRCs set forth in an attached pricing attachment, offer attachment, or a valid signed CenturyLink issued quote. Charges will commence within five days after the date CenturyLink notifies Customer that Service is provisioned and ready for use (“Start of Service Date”). Customer may order multiple Ports with multiple pricing methodologies in accordance with the pricing methodologies set forth below. Customer may change the pricing methodology (e.g., from Flat Rate to Precise Burstable) of a Port if: (a) the Port’s new MRC remains the same or greater than the old MRC, and (b) the Port starts a new Service Term that is equal to or greater than the remaining number of months in the old Service Term, subject to a 12 month minimum. CenturyLink may change rates after the completion of a Port’s Service Term with 60 days’ notice. The net rate MRCs set forth in the pricing attachment, offer attachment or valid signed CenturyLink issued quote will be used to calculate Contributory Charges. Net rate MRCs are lieu of all other rates, discounts, and promotions. The End-to-End Performance Reporting, VPN Extension, SIG and Multicast features are provided on a month-to-month basis and either party may cancel a feature with 30 days’ prior written notice to the other party. CenturyLink may upon 30 days prior written notice to Customer modify those features, including without limitation, their rates. If a CenturyLink IQ+ Port uses Data Center Access as the access type, that Port will be understood to be a CenturyLink IQ+ Cloud Port.

4.1 Pricing Methodologies.

(a) Flat Rate. The Flat Rate pricing methodology bills Customer a specified MRC for a given Port speed regardless of Customer’s actual bandwidth utilization.

(b) Tiered. The Tiered pricing methodology caps Customer’s bandwidth at the tier specified on an Order Form and bills the Customer a fixed MRC based on that bandwidth tier regardless of Customer’s actual bandwidth utilization. No more than once per month, Customer may change its specific bandwidth tier (e.g., 2 Mbps to10 Mbps) within the applicable Port classification (e.g., Ethernet, Fast Ethernet). Customer may not change its bandwidth from one Port classification to another.

(c) Precise Burstable. Usage samples are taken every five minutes throughout the monthly billing cycle. Only one sample is captured for each five-minute period, even though there are actually two samples taken; one for inbound utilization and one for outbound utilization. The higher of these two figures is retained. At the end of the billing period, the samples are ordered from highest to lowest. The top 5% of the samples are discarded. The highest remaining sample is used to calculate the usage level, which is the 95th percentile of peak usage. For each Precise Burstable Port, Customer will pay an MRC calculated by multiplying Customer’s 95th percentile of peak usage in a given month by the applicable MRC per Mbps. There is a minimum usage amount within each Precise Burstable Port classification (“Precise Burstable Minimum”). Customer will be billed the greater of the Precise Burstable Minimum or the actual charges based upon its 95th percentile of peak usage.

CENTURYLINK MASTER SERVICE AGREEMENT

DOMESTIC CENTURYLINK IQ^® NETWORKING SERVICE EXHIBIT

(d) Data Transfer. Usage samples are taken every five minutes throughout the Customer’s monthly billing cycle. Samples are taken for both in-bound utilization and out-bound utilization. Customer will be billed for the sum total of both inbound and outbound utilization. Charges are applied using a stepped or “metered” methodology such that Customer’s traffic will be billed incrementally at each volume tier. For example, if Customer’s total volume on a DS1 circuit is 10 GB, the first 7 GB of such total would be billed at the 0-7 GB tier, and the remaining 3 GB would be billed at the 7.01-17 GB tier. For each Data Transfer Port ordered hereunder, Customer will pay an MRC calculated by multiplying Customer’s volume of data transferred in a given month (in GBs) by the applicable MRC per GB. Within each Data Transfer Port classification (e.g., DS1, DS3), Customer will be subject to the minimum usage amount set forth in the column heading of the applicable Data Transfer pricing table (“Data Transfer Minimum”). Customer will be billed the greater of the Data Transfer Minimum or the actual charges based upon its actual volume of data transferred. Data Transfer pricing is only available if Customer’s premises-based router uses HDLC, PPP, or MLPPP line encapsulation.

5. Term; Cancellation.

5.1 Term. The term of an individual Port (and associated features/Services, if applicable) begins on the Start of Service Date for that Port and continues for (a) the service term shown on the valid signed CenturyLink issued quote or the pricing attachment or (b), if a service term is not shown in a quote or a pricing attachment, three years. If Service is installed at multiple Customer locations or with multiple Ports at a Customer location, each separate Port (and associated features/Services) will have its own Start of Service Date. Upon expiration of a Service Term, individual domestic Ports (and associated features/Services) will remain in effect on a month-to-month basis until canceled by either party with 60 days’ notice.

5.2 Cancellation. Upon cancellation of a Service, Customer will remain liable for charges accrued but unpaid as of the cancellation date. If a Port and associated features/Services is canceled by Customer other than for Cause, or by CenturyLink for Cause, before the conclusion of its Service Term or Upgrade Service Term (as described in the “Upgrades” section), Customer will pay a “Cancellation Charge” equal to the amounts set forth below. “Cause” means the failure of a party to perform a material obligation under the Agreement, which failure is not remedied: (a) for payment defaults by Customer, within five days of separate written notice from CenturyLink of such default; or (b) for any other material breach, within 30 days after written notice (unless a shorter notice period is identified in a Service Attachment).

(a) Domestic Internet Port orPrivate Ports: (i) 100% of the Port and NMS MRCs multiplied by the number of months remaining in the first 12 months of the initial Service Term (or Upgrade Service Term), if any, plus (ii) 35% of the balance of those MRCs multiplied by the number of months remaining to complete the initial Service Term (or Upgrade Service Term) beyond the first 12 months, plus (iii) the amount of any NRCs discounted or waived if the Port has not remained installed for at least 12 months.

(b) CenturyLink IQ+ Ports and CenturyLink IQ+ Cloud Ports: (i) 100% of the CenturyLink IQ+ Port or CenturyLink IQ+ Cloud Port MRC (and associated features/Service MRCs if applicable) multiplied by the number of months remaining in the first 12 months of the initial Service Term, if any; plus (ii) 75% of the those MRCs multiplied by the number of months remaining to complete 24 months of the initial Service Term, if any; plus, if applicable, (iii) 50% of those MRCs multiplied by the number of months remaining to complete the remainder of the Service Term.

5.3 Waiver of Cancellation Charges.

(a) Upgrades. CenturyLink will waive the Cancellation Charges for a domestic Port if Customer: (i) upgrades a Port to another Port with a higher bandwidth (e.g., from a DS1 to a DS3) within the same pricing methodology and the new Port’s MRC (with Local Access) is equal to or greater than the combined MRCs of the Port and the associated Local Access Service being terminated; or (ii) upgrades the Port type to a higher Port type (e.g., from an Internet Port to a Private Port or CenturyLink IQ+ Port) within the same pricing methodology. All upgraded Ports must start a new Service Term equal to or greater than the replaced Port’s remaining Service Term, subject to a 12 month minimum (“Upgrade Service Term”). If Customer cancels the upgraded Port before the completion of the Upgrade Service Term, Customer will pay the Cancellation Charges set forth in the Cancellation section above. In some cases an upgrade to a Port may trigger a Local Access charge under the Local Access Service Exhibit. Customer can upgrade a CenturyLink IQ+ Port from 8x5 NBD Remote to 24x7 On-Site maintenance or upgrade a CenturyLink IQ+ Port’s NMS feature to Select Management or Comprehensive Management without restarting the Service Term.

(b) Migration to Other CenturyLink Services. CenturyLink will waive the Cancellation Charges for a domestic Port if Customer migrates the Port to a new Data Bundle solution (a “New Service”) as long as: (i) the New Service’s MRC is equal to or greater than the combined MRCs of the Port and the associated Local Access Service being terminated; (ii) the New Service’s minimum service term is at least as long as the then remaining Service Term of the Port being terminated; and (iii) the New Service is available.

6. Additional Disclaimer of Warranty. In addition to any other disclaimers of warranty stated in the Agreement, CenturyLink makes no warranty, guarantee, or representation, express or implied, that all security threats and vulnerabilities will be detected or that the performance of the Services will render Customer’s systems invulnerable to security breaches. Customer is responsible for Customer’s own network security policy (including applicable firewall and NAT policies) and security response procedures.

Customer agrees to provide CenturyLink with any change to its e mail address.

8. AUP. All use of the Services must comply with the AUP located at http://www.centurylink.com/legal/, which is subject to change. CenturyLink may reasonably change the AUP to ensure compliance with applicable laws and regulations and to protect CenturyLink’s network and customers. Any changes to the AUP will be consistent with the purpose of the AUP to encourage responsible use of CenturyLink’s networks, systems, services, Web sites, and products.

9. SLA. Ports other than CenturyLink IQ+ Ports or CenturyLink IQ+ Cloud Ports are subject to the CenturyLink IQ Networking Service Level Agreement (“SLA”), CenturyLink IQ+ Ports and CenturyLink IQ+ Cloud Ports are subject to the CenturyLink IQ+ Port SLA and the NMS feature is subject to the NMS SLA. Each SLA is located at http://www.centurylink.com/legal/ and subject to change. For Customer’s claims related to Service or NMS feature deficiencies, interruptions or failures, Customer’s exclusive remedies are limited to those remedies set forth in the applicable SLA. References to CenturyLink IQ+ Ports in the CenturyLink IQ= SLA will also refer to CenturyLink IQ+ Cloud Ports.

10. Other Terms.

10.1 General. Any references to a Revenue Commitment or Contributory Charges will not apply to this Service Exhibit.

10.2. Cancellation and Termination Charges. This section replaces Section 4.6, the Cancellation and Termination Charges set forth in the Agreement:

Termination. Either party may terminate an individual Service: (a) as set forth above with 60 days’ prior written notice to the other party, or (b) for Cause. If an individual Service is terminated by Customer for any reason other than for Cause or by CenturyLink for Cause prior to conclusion of the applicable Service Term, then Customer will pay the Cancellation Charges set forth above, in addition to any and all charges that are accrued but unpaid as of the termination date. If the Agreement is terminated by Customer for any reason other than for Cause, or by CenturyLink for Cause prior to the conclusion of the Service Term, all Services are deemed terminated, and Customer will pay the Cancellation Charges set forth above, in addition to any and all charges that are accrued but unpaid as of the termination date.

10.3 Installation, Maintenance and Repair. The following are supplemental terms to the Scheduled Maintenance and Local Access section of the Agreement: (a) Provision of Services is subject to availability of adequate capacity and CenturyLink’s acceptance of a complete Order Form and (b) Customer is responsible for any facility or equipment repairs on Customer’s side of the demarcation point. Customer may request a technician dispatch for Service problems. Before dispatching a technician, CenturyLink will notify Customer of the dispatch fee. CenturyLink will assess a dispatch fee if it determines the problem is on Customer’s side of the demarcation point or was not caused by CenturyLink’s facilities or equipment on CenturyLink’s side of the demarcation point. “Order Form” includes both order request forms and quotes issued by CenturyLink. If a CenturyLink service requires a quote to validate the Order Form pricing, the quote will take precedence over the order request form, but not over the Service Exhibit.

10.4 Service Notices. Notices for disconnection of Service must be submitted to CenturyLink via Email at: BusinessDisconnects@Centurylink.com. Notices of non-renewal for Services must be sent via email to: CenturyLink, Attn.: CenturyLink NoRenew, e-mail: Norenew@centurylink.com. Notices for billing inquiries/disputes or requests for Service Level credits must be submitted to CenturyLink via Customer’s portal at https://www.centurylink.com/business/login/ or via Email at: Care.Inquiry@Centurylink.com. All other routine operational notices will be provided by Customer to its CenturyLink sales representative.

10.5 CPNI. CenturyLink is required by law to treat CPNI confidentially. Customer agrees that CenturyLink may share CPNI within its business operations (e.g., wireless, local, long distance, and broadband services divisions), and with businesses acting on CenturyLink’s behalf, to determine if Customer could benefit from the wide variety of CenturyLink products and services, and in its marketing and sales activities. Customer may withdraw its authorization at any time by informing CenturyLink in writing. Customer’s decision regarding CenturyLink’s use of CPNI will not affect the quality of service CenturyLink provides Customer. “CPNI” means Customer Proprietary Network Information, which includes confidential account, usage, and billing-related information about the quantity, technical configuration, type, destination, location, and amount of use of a customer’s telecommunications services. CPNI reflects the telecommunications products, services, and features that a customer subscribes to and the usage of such services, including call detail information appearing in a bill. CPNI does not include a customer’s name, address, or telephone number.

10.6 Conflicts. If a conflict exists among the provisions of the Service Attachments, the order of priority will be as follows: the Service Exhibit, the general terms of the Agreement, SLA, SOW (if any) and Order Form, as applicable, and then any other documents attached or expressly incorporated into the Agreement.

CENTURYLINK MASTER SERVICE AGREEMENT

LOCAL ACCESS SERVICE EXHIBIT

1. General. CenturyLink will provide Local Access Service (“Service”) under the terms of this Service Exhibit, the Agreement and the RSS.

2. Service Description and Availability.

2.1 Description. Service provides the physical connection between the Service Address and the CenturyLink Domestic Network. Service includes any entrance cable or drop wire to, and equipment maintained by CenturyLink at the Demarcation Point, but does not include CPE, Extended Wiring unless CenturyLink notifies customer that Extended Wiring is included with a service offering, inside wiring, or other equipment not maintained by CenturyLink. Customer is responsible for any additional terminations beyond the Demarcation Point. All equipment owned by CenturyLink remains property of CenturyLink. Customer disclaims any interest in any equipment, property or licenses used by CenturyLink to provide Service. CenturyLink will not provide Service to a residential location, even if business is conducted at that location. Service is not a standalone service and Customer must purchase the Service in connection with another CenturyLink service for which a local loop is required.

2.2 Types of Service Technologies. CenturyLink uses the following different technologies to provide Service. Some technologies or speeds may not be available in all areas or with certain types of Service.

(a) Special Access. “Special Access” means Service using digital signal bandwidths DS0, DS1 and DS3 or Optical Carrier signal bandwidths OC3, OC12, OC48 and OC192.

(b) Ethernet Local Access (“ELA”). ELA is available at bandwidths varying from 1 Mbps to 1,000 Mbps (1G) and 10G (Cross-Connect Access only). ELA is available in the following options: Native Single-Class-of-Service (CoS) Low, Native Single-CoS Medium, Native Single-CoS High, Native Multi-CoS, ELA over SONET, or Ethernet Virtual Access (“EVA”). “Native Single-CoS Low” is a layer 2, switched, native service using a standard Ethernet offering from the local access provider. Native Single-CoS Low is not recommended for use with critical applications (i.e. voice), but is ideal for non-critical applications (i.e. Internet and email traffic). “Native Single-CoS Medium” is a layer 2, switched, native service using a better-than-standard Ethernet offering from the local access provider. Native Single-CoS Medium is ideal for a combination of non-critical and/or critical applications; typically varying voice, video, and data. “Native Single-CoS High” is a layer 2, switched, native service using the best Ethernet offering from the local access provider. Native Single-CoS High is ideal for critical applications; typically predictable and reliable voice and data. Native Single-CoS Medium and Native Single-CoS High are only available with the following CenturyLink services: CenturyLink IQ^® Networking Internet Port, Private Port or Enhanced Port with Secure Internet Gateway, E-Line, or Ethernet Private Line (“EPL”). Native Single-CoS Medium or Native Single-CoS High circuit speed must match the maximum CenturyLink IQ Networking port, E-Line, or EPL bandwidth. “Native Multi-CoS” is a layer 2, switched, native service closely aligning the CenturyLink IQ Networking QoS and the local access provider’s Ethernet class of service offering and is only available with CenturyLink IQ Networking Private Port or Enhanced Port with Secure Internet Gateway. At Customer’s discretion, Native Single-CoS Low, Native Single-CoS Medium, Native Single-CoS High, or Native Multi-CoS may be used to support CoS for critical applications (i.e. voice). “ELA over SONET” is a layer 1, SONET-based service. EVA is a layer 2, Ethernet-based service that provides customers with a premium non-oversubscribed connection with Fast E and Gig E connection types. Customer may experience delayed installation intervals due to construction requirements and available bandwidths may be limited due to distance and available Ethernet-supported facilities from the local access provider.

(c) Wavelength Local Access. “Wavelength Local Access” means Service using wave division multiplexing technology. Wavelength Local Access is available at bandwidths of 1 GbE, 10 GbE LAN PHY, 2.5 G (OC48), 10 GbE WAN PHY (OC192), 40G, OTU1, OTU2, OTU3, 1G, 2G, 4G and 10G.

(d) DSL Local Access. “DSL Local Access” means Leased Access using digital subscriber line (“DSL”) technology. DSL Local Access is available at bandwidths varying from 128 kbps/64 kbps to 15000 Mbps/1000 Mbps. Customer may experience delayed installation intervals due to Construction requirements and available bandwidths may be limited due to distance and available DSL-supported facilities from the local access provider.

2.2.1 Use of IP Connection. In some locations, CenturyLink will enable the Service using “IP Connection” which is a Layer 3, symmetrical functionality that utilizes established IP and MPLS transport technologies. In such cases, Customer agrees that it will use IP Connection functionality only for the provision of either: (i) wireline broadband Internet access (as defined in applicable Federal Communications Commission orders and regulations), or (ii) wireline broadband Internet access plus additional information services, with wireline broadband Internet access constituting a principal use. CenturyLink can provision IP Connection functionality over multiple designs with MPLS transport supporting speeds up to 1G/1G.

2.3 Types of Service. CenturyLink offers the following three types of Service: CenturyLink Provided Access, Customer Provided Access or Cross-Connect Access.

2.3.1 CenturyLink Provided Access. “CenturyLink Provided Access” or “CLPA” means either On-Net Access or Leased Access.

(a) On-Net Access. For On-Net Access, Customer must be located in a CenturyLink designated building in which On-Net Access is generally available. On-Net Access is generally available as Special Access (except at the DS0 bandwidth), ELA, and Wavelength Local Access. Depending on the Service Address, On-Net Access may be provided through an existing CPOP, newly built CPOP, existing intra-building local loop facilities, or connections to a third party provider where CenturyLink coordinates the connectivity between CenturyLink facilities and facilities of a service provider with whom CenturyLink is interconnected. On-Net Access is subject to the OnNet Service Level Agreement located at http://www.centurylink.com/legal/docs/Local-Access-SLA.pdf, which is subject to change.

CENTURYLINK MASTER SERVICE AGREEMENT

LOCAL ACCESS SERVICE EXHIBIT

(b) Leased Access. Leased Access is generally available as Special Access, ELA, Wavelength Local Access and DSL Local Access at the bandwidths described in this Service Exhibit for those access types. Customer may request a Preferred Provider for Leased Access from a list of available providers with whom CenturyLink has interconnect agreements. CenturyLink will attempt to use Customer’s Preferred Provider, but both final routing and the provider actually used will be chosen by CenturyLink. If CenturyLink is unable to use Customer’s Preferred Provider for a specific Service Address as designated in the pricing attachment or a quote, then the rate for Service at that Service Address may be subject to change. Where available for Special Access, ELA and Wavelength Local Access, Customer may request CenturyLink to provide a separate fiber facility path for a protection system between the local access provider’s serving wire center and the Service Address (“Protect Route”). Protect Route uses backup electronics and two physically separate facility paths in the provisioning of Service. If the working facility or electronics fail, or the Service performance becomes impaired, the facility is designed to automatically switch to the Service protect path in order to maintain a near-continuous flow of information between locations. Special Access and ELA are also generally available as a central office meet point at a local access provider central office to which Customer has a dedicated connection.

2.3.2 Customer Provided Access. “Customer Provided Access” or “CPA” means a local loop that Customer orders from a local access provider to connect Customer’s premises to the CenturyLink Domestic Network at a connection point specified by CenturyLink. CenturyLink will provide Customer with a limited letter of agency (“LOA”), which is incorporated by this reference, authorizing Customer to act as CenturyLink’s agent so that Customer’s local access provider will connect Customer’s premises to the CenturyLink Domestic Network. Customer will also need to execute a CPA-DAR Addendum for CPA POP with ELA or Wavelength Local Access. Customer will pay a CPA charge to CenturyLink when Customer uses the following: (a) Special Access CPA dedicated facilities or ELA CPA virtual local area network (“VLAN”), both of which are dedicated entrance facilities CenturyLink leases from a local access provider and that carry traffic only from CenturyLink; or (b) ELA CPA POP, which requires CenturyLink to provide space and power for the local access provider to install Ethernet equipment; or (c) Wavelength Local Access. Customer will pay a CPA charge to CenturyLink when Customer uses Special Access CPA non-dedicated facilities owned by local access providers and that carry traffic from multiple carriers, including CenturyLink, if the provider charges CenturyLink for those facilities. CPA ELA VLAN is an access type where CenturyLink will provision and assign an Ethernet virtual circuit from a CenturyLink POP to a Customer designated Ethernet facility leased from a common Ethernet service provider. This access will be used to connect to a CenturyLink VLAN assignment on a CenturyLink IQ Networking Internet or Private Port or E-Line. CenturyLink will not bill customer a CPA charge for an IP layer 3 expansion site because Customer, not CenturyLink, is responsible for ordering a cross-connect from the IP layer 3 expansion site manager to meet CenturyLink in the IP layer 3 expansion site’s meet-me-room. CPA is the responsibility of Customer and CenturyLink will not pay for or troubleshoot components of CPA.

2.3.3 Cross-Connect Access. “Cross-Connect Access” or “XCA” means: (a) an intra-POP connection between certain Customer facilities with direct access to the CenturyLink Domestic Network and the CenturyLink backbone access point (either (i) located within CenturyLink’s transport area where CenturyLink allows Customer to bring its own fiber directly to the CenturyLink fiber under an executed Direct Connect Agreement (“Direct Connect”) or (ii) in an area where Customer has leased space in a CPOP, a remote collocation site, or a collocation hotel under a Telecommunications Collocation License Agreement or (b) a connection between a CenturyLink-determined data center and a CenturyLink IQ Networking Port, Optical Wavelength Service (“OWS”), or E-Line (“Data Center Access”) under an executed CenturyLink TS Service Exhibit with a CenturyLink IQ Networking, OWS or E-Line Service Exhibit. Data Center Access is available in bandwidths of 100 Mbps, 1G, and 10G (CenturyLink IQ Networking and OWS only). Direct Connect requires splicing of Customer and CenturyLink fibers and cross-connection of individual circuits.

2.4 RSS. Customer understands that Service is an interstate telecommunications service, as defined by Federal Communications Commission regulations and represents while using the Service, more than 10% of its usage will be interstate usage.

3. Ordering. Upon acceptance of an order for a Service, CenturyLink will notify Customer of CenturyLink’s target date for the delivery of that Service (“Estimated Availability Date”). Once CenturyLink notifies Customer of the Estimated Availability Date for a Service, cancellation fees or Cancellation Charges set forth in the Cancellation section below will apply to any cancellation of that order. If Customer fails to respond to CenturyLink’s requests to arrange for the installation of a Service when CenturyLink is ready, CenturyLink may consider the affected Service order canceled. CenturyLink will use commercially reasonable efforts to install each such Service on or before the Estimated Availability Date, but the inability of CenturyLink to deliver Service by such date is not a default under the Agreement or this Service Exhibit.

4. Charges. Customer will pay the net rates set forth in the attached pricing attachment or a quote for Service issued by CenturyLink if the rates for Service at a particular Service Address are not included in the pricing attachment, including all applicable ancillary service charges. CenturyLink invoices MRCs in advance and NRCs in arrears. If the Start of Service Date for any Service falls on any day other than the first day of the month, the first invoice to Customer will consist of: (a) the pro-rata portion of the applicable MRC covering the period from the Start of Service Date to the first day of the subsequent month; and (b) the MRC for the following month. Charges for Service will not be used to calculate Contributory Charges. Customer will receive the rates for Service as shown on the pricing attachment regardless of whether an NPA/NXX split or overlay occurs.

CENTURYLINK MASTER SERVICE AGREEMENT

LOCAL ACCESS SERVICE EXHIBIT

4.1 Ancillary Charges. Ancillary charges applicable to Service include but are not limited to those ancillary services set forth in this section. If an ancillary charge applies in connection with provisioning a particular Service, CenturyLink will notify Customer of the ancillary charge to be billed to Customer. Customer may either approve or disapprove CenturyLink providing the ancillary service.

(a) Expedite. A local loop expedite charge applies to orders where Customer requests the delivery of Service one or more days before the Estimated Availability Date. Customer may only request to expedite CenturyLink Provided Access of Special Access and ELA orders (where underlying local access provider allows CenturyLink QCC to order an expedited service.)

(b) Extended Wiring. “Extended Wiring” means additional wiring from the Demarcation Point to Customer’s network interface equipment. Customer may only request Extended Wiring for (i) Special Access ordered as Leased Access, (ii) DSL Local Access, and (iii) Ethernet Local Access (where available). Extended Wiring could entail electrical or optical cabling into 1) existing or new conduit or 2) bare placement in drop down ceilings, raised floors, or mounted to walls/ceilings. Once Service is accepted by Customer, the Extended Wiring then becomes property of and maintained by Customer. CenturyLink will maintain Service to the Demarcation Point only.

(c) Construction. Construction charges apply if; (i) special construction is required to extend Service to the Demarcation Point; or (ii) other activities not covered by Extended Wiring are required beyond the Demarcation Point, that cause CenturyLink to incur additional expenses for provisioning the Service (“Construction”). If Customer does not approve of the Construction charges after CenturyLink notifies Customer of the charges, the Service ordered will be deemed cancelled.

(d) Multiplexing. Customer may request multiplexing for Special Access where available. CenturyLink will multiplex lower level local loop into a higher local loop, or vice-versa, for an additional charge. CenturyLink offers multiplexing at a CPOP, at an On-Net Access building or at an ILEC/CLEC facility providing the Leased Access. For multiplexing at a CenturyLink On-Net Access building, CenturyLink provides multiplexed circuit handoffs to Customer at the same On-Net Access Service Address. For multiplexing at ILEC/CLEC facility, CenturyLink facilitates the delivery of multiplexed circuit handoffs to Customer at a single Service Address or at multiple Service Addresses per Customer’s request. Multiplexing is generally available at DS1 and OCn circuit levels. Pricing for multiplexing at an ILEC/CLEC facility is on an individual case basis.

(e) Changes. Ancillary change charge applies where Customer requests CenturyLink to change a local loop to a different Service Address that is within the same Customer serving wire center as the existing local loop, but a Cancellation Charge does not apply.

5. Term; Cancellation.

5.1 Term. The term of an individual Service begins on the Start of Service Date for that Service and continues for the number of months specified in the attached pricing attachment for a particular Service Address or a quote for Service issued by CenturyLink if the rates for Service at particular Service Address are not included in the pricing attachment (“Initial Service Term”). Excluding voice loops and Data Center Access with a month-to-month Initial Service Term, the Initial Service Term will not be less than 12 months. Upon expiration of the Initial Service Term, Service will automatically renew for consecutive periods equal to the Initial Service Term length (a “Renewal Service Term”). CenturyLink may change rates at any time after the Initial Service Term, but will not change rates more than once during a Renewal Service Term.

5.2 Cancellation. Upon cancellation of a Service, Customer will remain liable for (a) charges accrued but unpaid as of the cancellation date (including MRCs, NRCs and Construction charges and other ancillary charges), (b) the amount of any NRCs that CenturyLink discounted or waived, if canceled during the first 12 months of the Initial Service Term and (c) any applicable cancellation fees and Cancellation Charges as set forth below.

(a)  Leased Access and On-Net Access—Cancellation Before the Start of Service Date. Customer will pay the cancellation fee identified in the below table if cancellation of a Service order occurs before the Start of Service Date. If Customer accepted a Construction charge, Customer will also pay any unpaid Construction charges incurred by CenturyLink. If CenturyLink notifies Customer that Construction is required to provision a Service order and Customer cancels that order before the Start of Service Date because Customer disapproves of the Construction charge, the cancellation fee does not apply.

†Includes all types of Service Technology unless otherwise noted.

(b) All Service Types—Cancellation After the Start of Service Date. If a Service is canceled by Customer other than for Cause, or by CenturyLink for Cause, before the conclusion of its Initial Service Term, Customer will pay a “Cancellation Charge” equal to: (i) 100% of the balance of the MRCs that otherwise would have become due for the unexpired portion of the first 12 months of the Initial Service Term, if any, plus (ii) 35% of the balance of the MRCs that otherwise would have become due for the unexpired portion, if any, of the Initial Service Term beyond the first 12 months.

(c) Moves. When Customer requests that CenturyLink move a local loop to a different Service Address that is not within the same Customer serving wire center as the existing local loop such move will be deemed a disconnect of the current local loop to which a Cancellation Charge applies and a new install of a new local loop.

CENTURYLINK MASTER SERVICE AGREEMENT

LOCAL ACCESS SERVICE EXHIBIT

(d) Waiver of Cancellation Charges. CenturyLink will waive the Cancellation Charge for a cancelled Service:

(e) Customer Provided Access—Cancellation of Connectivity after Start of Service Date. To cancel CPA, Customer must provide CenturyLink with a written disconnect firm order confirmation (“DFOC”) notice from Customer’s CPA provider along with notice to cancel the CPA. If Customer fails to provide CenturyLink with the DFOC notice within 30 calendar days after CenturyLink’s receipt of the notice to cancel the CPA, or if CenturyLink disconnects CPA for Cause, then CenturyLink may disconnect the CPA or require the CPA provider to do so. Customer will remain liable for charges for the connectivity to CPA (even if Customer cannot use the CPA) until: (i) Customer furnishes the required DFOC to CenturyLink; or (ii) either party cancels the associated CPA with the CPA provider.

6. Grooming. If CenturyLink plans to groom a circuit on which Service is provided, CenturyLink will provide a grooming notice to Customer. For CPA dedicated facilities grooming, Customer will provide a signed LOA to CenturyLink so that CenturyLink can order the necessary changes. Within 20 calendar days after receipt of that notice, Customer will: (a) notify CenturyLink of its approval, which may not be unreasonably withheld; (b) state its reason for refusing; or (c) request that CenturyLink provide Customer with an LOA so Customer can order the necessary changes. Customer’s failure to respond within the 20-day period will constitute approval of the groom. If the groom results in Customer incurring additional NRCs from its local access provider and Customer provides sufficient proof of the local access provider charge, CenturyLink will issue a credit to Customer equal to the local access provider NRC for each groomed circuit. If Customer refuses the groom for On-Net Access, CenturyLink will, upon 20 calendar days’ prior written notice, cancel the Service on that circuit and assess a Cancellation Charge. When Customer does not respond to a CPA dedicated facilities grooming notice or refuses a CPA dedicated facilities groom, Customer must either: (a) provide CenturyLink with a LOA/CFA so that CenturyLink can have the local access provider cancel the circuit; or (b) work directly with the local access provider to cancel the circuit. If Customer does neither of these things, CenturyLink will pass through to Customer any costs incurred by CenturyLink from the local access provider as a result of the circuit remaining in place. “CFA” means circuit facility assignment of the CenturyLink facility, as identified by CenturyLink, to which Customer must order a local loop for connection to the CenturyLink Domestic Network.

7. Other Terms.

7.1 General. Any references to a Revenue Commitment or Contributory Charges will not apply to this Service Exhibit.

7.2. Cancellation and Termination Charges. This Section replaces Section 4.6, the Cancellation and Termination Charges set forth in the Agreement:

Termination. Either party may terminate an individual Service: (a) as set forth above with 60 days’ prior written notice to the other party, or (b) for Cause. If an individual Service is terminated by Customer for any reason other than for Cause or by CenturyLink for Cause prior to conclusion of the applicable Service Term, then Customer will pay the termination charges set forth above, in addition to any and all charges that are accrued but unpaid as of the termination date. If the Agreement is terminated by Customer for any reason other than for Cause, or by CenturyLink for Cause prior to the conclusion of the Term, all Services are deemed terminated, and Customer will pay the termination charges set forth above, in addition to any and all charges that are accrued but unpaid as of the termination date. “Cause” means the failure of a party to perform a material obligation under the Agreement, which failure is not remedied: (a) for payment defaults by Customer, within five days of separate written notice from CenturyLink of such default; or (b) for any other material breach, within 30 days after written notice (unless a shorter notice period is identified in a Service Attachment).

7.3 Installation, Maintenance and Repair. The following are supplemental terms to the Scheduled Maintenance and Local Access section of the Agreement: (a) Provision of Services is subject to availability of adequate capacity and CenturyLink’s acceptance of a complete Order Form and (b) Customer is responsible for any facility or equipment repairs on Customer’s side of the demarcation point. Customer may request a technician dispatch for Service problems. Before dispatching a technician, CenturyLink will notify Customer of the dispatch fee. CenturyLink will assess a dispatch fee if it determines the problem is on Customer’s side of the demarcation point or was not caused by CenturyLink’s facilities or equipment on CenturyLink’s side of the demarcation point. “Order Form” includes both order request forms and quotes issued by CenturyLink. If a CenturyLink service requires a quote to validate the Order Form pricing, the quote will take precedence over the order request form, but not over the Service Exhibit.

7.4 Service Notices. Notices for disconnection of Service must be submitted to CenturyLink via Email at: BusinessDisconnects@Centurylink.com. Notices of non-renewal for Services must be sent via email to: CenturyLink, Attn.: CenturyLink NoRenew, e-mail: Norenew@centurylink.com.

Within the five-day timeframe, if Customer neither informs CenturyLink about errors nor accepts the circuit, the circuit will be considered to have been accepted and the Start of Service Date to have commenced on the fifth day following CenturyLink’s ready notification, regardless of whether Customer placed traffic over the circuit. If Customer informs CenturyLink of circuit errors within the five-day timeframe, CenturyLink will promptly take necessary, reasonable action to correct the errors, and upon correction, notify Customer that the circuit is ready.

Customer may withdraw its authorization at any time by informing CenturyLink in writing. Customer’s decision regarding CenturyLink’s use of CPNI will not affect the quality of service CenturyLink provides Customer. “CPNI” means Customer Proprietary Network Information, which includes confidential account, usage, and billing-related information about the quantity, technical configuration, type, destination, location, and amount of use of a customer’s telecommunications services. CPNI reflects the telecommunications products, services, and features that a customer subscribes to and the usage of such services, including call detail information appearing in a bill.

DOMESTIC VOICE SERVICE EXHIBIT

1. General; Definitions. Capitalized terms not defined in this Service Exhibit are defined in the Agreement. CenturyLink will provide domestic Voice Services (“Service”) under the terms of the Agreement, Tariff, RSS, ISS, and this Service Exhibit.

“Access Arbitrage” is the use of a scheme, device or any other means to exploit or benefit from the difference between the rates for Voice Services provided by CenturyLink and the originating or terminating charges imposed by the Local Exchange Carrier (“Access Arbitrage”). Examples of Access Arbitrage include: (i) using switching equipment or a call processing system (such as a prepaid card, calling card, or teleconferencing platform) to segregate calls and systematically route to CenturyLink calls that are characterized by a greater discrepancy between the access costs and the price charged by CenturyLink; (ii) routing calls through a call processing system such that the percentage of high cost minutes routed to CenturyLink using the Service is more than 11.4%; (iii) segregating calls within another carrier’s network or a call processing system to systematically route calls to CenturyLink where the access costs exceed the price of long distance service provided by CenturyLink; (iv) transporting intrastate traffic into a different state in order to cause the traffic to be rated by CenturyLink at a lower Interstate rate than would otherwise apply; or (v) any other means to exploit or benefit from the difference between the rates for Services and the originating or terminating access charges imposed by the local exchange carrier.

“Net Effective Rate” means the rates less the Custom Discount. Net Effective Rates are subject to change if there is a change in the underlying rates and/or applicable discount(s), with any such changes to be done in accordance with the terms of the Agreement or this Service Exhibit.

“Net Rate” is in lieu of all other rates, discounts, and promotions.

“SLA” means the service level agreement specific to the Service, located at http://www.centurylink.com/legal/, which is subject to change.

2. Service.

2.1 Description. Voice Service consists of domestic Long Distance, domestic Toll Free (including features), domestic Virtual Network Service (“VNS”), domestic worldcard^®, and domestic Directory Assistance Services. Domestic Long Distance Service is available both interstate and intrastate, through switched and dedicated facilities. Toll Free service is also available through switched or dedicated facilities. CenturyLink is required by the Federal Communications Commission (“FCC”) to state in this Service Exhibit that Customer is prohibited from using any Toll Free telephone number, or other telephone number advertised or widely understood to be Toll Free, in a manner that would violate FCC rule 47 CFR 64.1504. Directory Assistance offers one rate to Voice Service customers domestically. With respect to Outbound Long Distance: (a) Per the Federal Trade Commission (“FTC”), telemarketers are required to transmit their telephone number to Caller ID services. As such, all telemarketers using CenturyLink commercial services are required to provide CPN/pseudo-CPN according to the rules below: IF A TELEMARKETER DOES NOT PROVIDE CENTURYLINK WITH A NUMBER FOR THIS PURPOSE, THEIR BILLING TELEPHONE NUMBER WILL BE USED AS THE TRUNK GROUP’S CPN; and (b) Federal Do Not Calls rules require that companies that telemarket or engage in telephone solicitations adhere to the requirements set forth in 47 C.F.R. section 64.1200 (FCC) and 16 C.F.R. Part 310 (FTC). Please consult with your company’s legal advisor for more information. The SLA provides Customer’s sole and exclusive remedy for service interruptions or service deficiencies of any kind whatsoever for the Service. worldcard offers domestic calling card services available either interstate or intrastate and is available through switched access only. worldcard is offered with three options: (c) the standard option includes CenturyLink’s trademarks and telephone number; (d) the “cologo” option includes CenturyLink’s and Customer’s names and trademarks and/or logos and will include either CenturyLink’s or Customer’s telephone number; and (e) the “private label” option only includes Customer’s names trademarks and/or logos and will include either CenturyLink’s or Customer’s telephone number. If Customer selects the cologo or private label worldcard options, then Customer grants CenturyLink permission to create a card using Customer’s name, trademarks and/or logos as provided to CenturyLink by Customer. Customer further agrees that even though Customer’s name, trademarks, logo and/or phone number may appear on the cards, except for Customer’s rights in its name, trademarks, and/or logo, CenturyLink will be sole owner of all right and title in and to all intellectual property associated with the cards and the worldcard service. Furthermore, if Customer selects either the cologo or private label cards, then Customer agrees to indemnify and hold CenturyLink harmless for any costs, fees, damages, or expenses of any sort incurred by CenturyLink as a result of claims arising from CenturyLink’s use of Customer’s name, trademarks or logo in accordance with this Agreement. In addition to the other worldcard charges listed in the pricing document provided to Customer, Customer will pay to CenturyLink any set-up charges associated with the design and production of the cologo and private label cards. CenturyLink will notify Customer of the total amount of set-up charges prior to production of the cards. If Customer objects to the set-up charges, then the parties will work together to create a less expensive design than originally requested by Customer (this sentence and the previous sentence combined constitute the “Set-up Process”). If Customer revokes the use of its mark for the cologo or private label cards or requests new cards due to its mark changing, then Customer must cease using those cards and CenturyLink will issue replacement cards that either do not include Customer’s mark or contain the new mark, as appropriate. The Set-up Process will apply to the replacement cards and Customer will pay CenturyLink the set-up charges for the replacement cards. The person(s) named on the calling card and those identified on CenturyLink’s records for the associated account are jointly and severally responsible for the charges made using the calling card. The calling card is not transferable, but the cardholder may authorize others to use it. The cardholder is responsible for all charges incurred by authorized users, and giving the calling card to someone else or telling someone else the security code is such authorization. The calling card will be cancelled at the cardholder’s request. CenturyLink may cancel the calling card if the cardholder cancels or fails to pay, if CenturyLink suspects fraud, improper, or unauthorized use or observes unusual use, or if it changes its policies for issuing worldcard calling cards. CenturyLink may cancel the calling card without notice. CenturyLink is not liable for any damages for any reason due to the cancellation of, or failure to accept the calling card. If a calling card is canceled for any reason, the cardholder must notify all authorized users and destroy all calling cards. The cardholder should notify CenturyLink immediately if the cardholder changes address or telephone number or if a calling card is lost, stolen, or misplaced or if a cardholder suspects unauthorized use or misuse of a calling card. To report a loss, theft, or suspected misuse, please call 1 800-860-1020. Some uses of the worldcard calling card may be subject to rules, regulations, and tariffs of state public utility commissions and the Federal Communications Commission.

CENTURYLINK MASTER SERVICE AGREEMENT

DOMESTIC VOICE SERVICE EXHIBIT

2.2 Domestic IP Voice. Domestic IP Voice Service consists of IP intrastate and interstate dedicated Long Distance and IP dedicated Toll Free. Domestic IP Voice accepts intrastate and interstate dedicated Long Distance traffic in IP format and converts such traffic for transmission across the telecommunications network. Domestic IP Voice also accepts domestic Toll Free traffic and converts it into VoIP format for transmission to Customer. The pricing for Domestic IP Voice services is the same as for non-IP intrastate and interstate dedicated Long Distance and non-IP dedicated Toll Free. Domestic IP Voice does not support local services, 911, E911, V911, operator services, local number portability, or directory listings. All use of Domestic IP Voice will comply with and be subject to the service guide, AUP, and applicable sections of the SLA which are posted at http://www.centurylink.com/legal/. CenturyLink reserves the right to refuse to accept, suspend, or limit any or all of Customer’s IP traffic not complying with the service guide technical specifications or that CenturyLink believes is adversely affecting other customers on the CenturyLink network. The service guide and AUP are incorporated into the Agreement by this reference. CenturyLink may reasonably modify the service guide, AUP, and SLA to ensure compliance with applicable laws and regulations and to protect CenturyLink’s network and customers, and such change will be effective upon posting to the Web site.

2.3 CenturyLink 8XX Outbound Service. CenturyLink 8XX Outbound Service (“8XX Outbound”) allows Customer to place Toll Free Outbound TDM or IP calls to CenturyLink owned or non-CenturyLink owned Toll Free numbers on Customer’s CenturyLink dedicated access lines (“DALS”). 8XX Outbound is only available on DALs provisioned on CenturyLink DMS250, NGS, and IPLD switched. 8XX Outbound is not subject to an SLA. 8XX Outbound is governed by the CenturyLink RSS and/or Tariffs. CenturyLink reserves the right, upon 30 calendar days prior written notice to Customer, to cancel or modify 8XX Outbound. If Customer does not agree to the 8XX Outbound modifications, then Customer must notify CenturyLink prior to the expiration of the 30 day time frame that Customer wishes to cancel 8XX Outbound. Customer’s continued use of 8XX Outbound after the 30-day time frame will indicate that Customer agrees to the modifications. Limitations. CenturyLink provides 8XX Outbound by routing and terminating the toll-free call to a CenturyLink dedicated facility that is connected to a LEC facility to allow re-origination to the dialed toll-free number. CenturyLink is only responsible for getting the call to the LEC for re-origination. CenturyLink cannot provide any kind of support or help troubleshoot problems with Toll Free origination or termination once the call is delivered to the LEC for re-origination. Because all outbound Toll Free calls will re-originate from a LEC central office, the outbound toll-free call will route as if the call originates from the LEC central office, and not from the geographic location of Customer’s DAL. If there is regional (i.e., calls only allowed to originate from specific states or disallowed from specific states) or point of call (geographic) routing on the dialed toll-free number, the call may not be completed. From time to time CenturyLink may add, change, and/or remove the central offices from which calls are re-originated, without notice to Customer. Customer requests for 8XX Outbound changes or additions, including additional 8XX Outbound traffic volumes, are subject to availability and CenturyLink’s acceptance of the order.

3. Compliance.

3.1 Access Arbitrage. If CenturyLink determines the number of calls routed to CenturyLink using Access Arbitrage exceeds 11.4% of Customer’s total call volume, CenturyLink will apply a per minute Access Arbitrage Fee to 95% of their high cost minutes. In addition, CenturyLink may immediately restrict, suspend, or discontinue Service used in connection with Access Arbitrage upon notice of such violation to Customer. Inbound and outbound per minute “Access Arbitrage Fees” are $0.10 per minute for switched Services and $0.05 per minute for dedicated Services. For more detailed information about Access Arbitrage, please refer to the RSS.

3.2 Non-Completed Calls. “Non-completed Call Percentage Threshold” means 30% of all attempted calls, both completed and non-completed. If the percentage of Customer’s calls that do not complete (out of all attempted calls) meets or exceeds the Non-completed Call Percentage Threshold for any given monthly billing cycle, CenturyLink may, upon 30 calendar days notice to Customer, disconnect any and all circuit(s) providing Service on which the Non-completed Call Percentage Threshold was exceeded.

3. Term. This Service Exhibit will expire or terminate coterminous with the Agreement, unless terminated earlier by either party by providing 60 days advance written notice.

4. Charges. Customer will pay all applicable rates and charges for the Services and features set forth in the pricing document CenturyLink provides to Customer as part of the Agreement or an amendment to the Agreement. The Services and features are usage-based. If Customer uses a Service or feature for which CenturyLink has not provided the rates, Net Rates, or Net Effective Rates in a separate document, then Customer will pay the applicable Tariff, RSS, or ISS rates and charges for the subject Service or feature. Customer is responsible for all metered usage charges and per call charges that occur from the point Service is available for Customer use, regardless of whether CenturyLink notifies Customer of Service availability. Domestic Long Distance calls crossing state boundaries, within the same LATA, will be billed at the interstate rate. The rates, Net Rates, and Net Effective Rates do not include costs associated with local access or CPE, which rates are described in the Service Exhibits specific to those services or in a separate agreement for such service. Customer’s 8XX Outbound will bill the same rates as Customer’s dedicated outbound Long Distance (1+), except where otherwise noted on the pricing document provided to Customer. Customer understands and agrees that all 8XX Outbound calls will be billed to the trunk group owner, even if the dialed toll-free numbers belong to CenturyLink. CenturyLink reserves the right, upon 30 calendar days prior written notice to Customer, to charge an MRC for 8XX Outbound. If Customer does not agree to the MRC, then Customer must notify CenturyLink prior to the expiration of the 30 day time frame that Customer wishes to cancel 8XX Outbound. Customer’s continued use of 8XX Outbound after the 30-day time frame will indicate that Customer agrees to pay the MRC.

5. Other Terms.

5.1 General. Any references to a Revenue Commitment or Contributory Charges will not apply to this Service Exhibit.

CENTURYLINK MASTER SERVICE AGREEMENT

DOMESTIC VOICE SERVICE EXHIBIT

5.2. Cancellation and Termination Charges. This Section replaces Section 4.6, the Cancellation and Termination Charges set forth in the Agreement:

Termination. Either party may terminate an individual Service: (a) as set forth above with 60 days’ prior written notice to the other party, or (b) for Cause.

5.6 Acceptable Use Policy and Use of Service. CenturyLink may also terminate the Domestic IP Voice Service for Cause under this Section where Customer’s use of the Domestic IP Voice Service: (a) is contrary to the AUP, (b) constitutes an impermissible traffic aggregation or Access Arbitrage, (c) avoids Customer’s obligation to pay for communication services, and (d) violates the Use of Service terms or compliance terms. Customer may have obligations under 47 CFR 9.5 relating to 911 if Customer combines the Service with other products creating a VoIP or VoIP-like service that facilitates the transmission of voice services.

5.7 Use of Service. CenturyLink may also terminate Service for Cause under this Section where Customer’s use of the Service: (a) constitutes an impermissible traffic aggregation or Access Arbitrage, (b) avoids Customer’s obligation to pay for communication services, and (c) violates the use of Service terms or compliance terms applicable to the Service. “Cause” means the failure of a party to perform a material obligation under the Agreement, which failure is not remedied: (a) for payment defaults by Customer, within five days of separate written notice from CenturyLink of such default; or (b) for any other material breach, within 30 days after written notice (unless a shorter notice period is identified in a Service Attachment).

5.8 CPNI. CenturyLink is required by law to treat CPNI confidentially. Customer agrees that CenturyLink may share CPNI within its business operations (e.g., wireless, local, long distance, and broadband services divisions), and with businesses acting on CenturyLink’s behalf, to determine if Customer could benefit from the wide variety of CenturyLink products and services, and in its marketing and sales activities. Customer may withdraw its authorization at any time by informing CenturyLink in writing. Customer’s decision regarding CenturyLink’s use of CPNI will not affect the quality of service CenturyLink provides Customer. “CPNI” means Customer Proprietary Network Information, which includes confidential account, usage, and billing-related information about the quantity, technical configuration, type, destination, location, and amount of use of a customer’s telecommunications services. CPNI reflects the telecommunications products, services, and features that a customer subscribes to and the usage of such services, including call detail information appearing in a bill.

CENTURYLINK MASTER SERVICE AGREEMENT

INTERNATIONAL VOICE SERVICE EXHIBIT

1. General; Definitions. Capitalized terms not defined in this Service Exhibit are defined in the Agreement. CenturyLink will provide international voice service (“Service” or “International Voice Service”) under the terms of the Agreement, RSS, ISS, and this Service Exhibit.

“Net Rate” is in lieu of all other rates, discounts, and promotions.

“Pricing Attachment” means a document containing rates specific to the Service and is incorporated by reference and made a part of this Service Exhibit.

2. Service.

2.1 Description. Service consists of International Outbound Long Distance, International Toll Free and International worldcard^®. Except where specified otherwise, for international outbound voice service, the rates specified in the Pricing Attachment will only apply to international outbound voice service originating in the U.S. (subject to availability) and terminating internationally using land-line facilities and will not apply to international outbound voice service terminating internationally using cellular facilities or, for international inbound voice service, the rates specified in the Pricing Attachment will only apply to international inbound voice service originating internationally using land-line and cellular facilities. However, airtime is charged for mobile calls. With respect to International Outbound Long Distance: (a) Per the Federal Trade Commission (“FTC”), telemarketers are required to transmit their telephone number to Caller ID services. As such, all telemarketers using CenturyLink commercial services are required to provide CPN/pseudo-CPN according to the rules below: IF A TELEMARKETER DOES NOT PROVIDE CENTURYLINK WITH A NUMBER FOR THIS PURPOSE, THEIR BILLING TELEPHONE NUMBER WILL BE USED AS THE TRUNK GROUP’S CPN; and (b) Federal Do Not Calls rules require that companies that telemarket or engage in telephone solicitations adhere to the requirements set forth in 47 C.F.R. section 64.1200 (FCC) and 16 C.F.R. Part 310 (FTC). Please consult with your company’s legal advisor for more information.

2.2 International IP Voice. International IP Voice Service consists of IP international Long Distance and IP dedicated international Toll Free. International IP Voice accepts international dedicated Long Distance traffic in IP format and converts such traffic for transmission across the telecommunications network. International IP Voice also accepts dedicated international Toll Free traffic and converts it into VoIP format for transmission to Customer. The pricing for International IP Voice services is the same as for non-IP dedicated international Long Distance and Toll Free. International IP Voice does not support local services, 911, E911, V911, operator services, local number portability, or directory listings. All use of International IP Voice will comply with and be subject to the service guide and AUP which are posted at http://www.centurylink.com/legal/. CenturyLink reserves the right to refuse to accept, suspend, or limit any or all of Customer’s IP traffic not complying with the service guide technical specifications or that CenturyLink believes is adversely affecting other customers on the CenturyLink network. The service guide and AUP are incorporated into the Agreement by this reference. CenturyLink may reasonably modify the service guide and AUP to ensure compliance with applicable laws and regulations and to protect CenturyLink’s network and customers, and such change will be effective upon posting to the Web site.

2.3 Non-Completed Calls. “Non-completed Call Percentage Threshold” means 30% of all attempted calls, both completed and non-completed. If the percentage of Customer’s calls that do not complete (out of all attempted calls) meets or exceeds the Non-completed Call Percentage Threshold for any given monthly billing cycle, CenturyLink may, upon 30 calendar days notice to Customer, disconnect any and all circuit(s) providing Service on which the Non-completed Call Percentage Threshold was exceeded.

3. Term. This Service Exhibit will expire or terminate coterminous with the Agreement, unless terminated earlier by either party by providing 60 days advance written notice.

4. Charges. Customer will pay all applicable rates and charges as set forth in the Pricing Attachment, in the RSS, or Order Form. Rates not addressed in the Pricing Attachment, in the RSS, or Order Form can be found at http://centurylink.com/legal/ildctaexp/ildezaildtfezd/v4.doc. The rates will be used to calculate Contributory Charges. The rates for Service are controlled by the RSS and are subject to change. The rates set forth at http://centurylink.com/legal/ildctaexp/ildezaildtfezd/v4.doc and in the Pricing Attachment do not include costs associated with local access.

5. Other Terms.

5.1 General. Any references to a Revenue Commitment or Contributory Charges will not apply to this Service Exhibit.

Termination. Either party may terminate an individual Service: (a) as set forth above with 60 days’ prior written notice to the other party, or (b) for Cause. If an individual Service is terminated by Customer for any reason other than for Cause or by CenturyLink for Cause, then Customer will pay any and all charges that are accrued but unpaid as of the termination date. If the Agreement is terminated by Customer for any reason other than for Cause, or by CenturyLink for Cause prior to the conclusion of the Term, all Services are deemed terminated, and Customer will pay any and all charges that are accrued but unpaid as of the termination date. “Cause” means the failure of a party to perform a material obligation under the Agreement, which failure is not remedied: (a) for payment defaults by Customer, within five days of separate written notice from CenturyLink of such default; or (b) for any other material breach, within 30 days after written notice (unless a shorter notice period is identified in a Service Attachment).

CENTURYLINK MASTER SERVICE AGREEMENT

INTERNATIONAL VOICE SERVICE EXHIBIT

5.3 Installation, Maintenance and Repair. The following are supplemental terms to the Scheduled Maintenance and Local Access section of the Agreement: (a) Provision of Services is subject to availability of adequate capacity and CenturyLink’s acceptance of a complete Order Form and (b) Customer is responsible for any facility or equipment repairs on Customer’s side of the demarcation point. Customer may request a technician dispatch for Service problems. Before dispatching a technician, CenturyLink will notify Customer of the dispatch fee. CenturyLink will assess a dispatch fee if it determines the problem is on Customer’s side of the demarcation point or was not caused by CenturyLink’s facilities or equipment on CenturyLink’s side of the demarcation point. “Order Form” includes both order request forms and quotes issued by CenturyLink. If a CenturyLink service requires a quote to validate the Order Form pricing, the quote will take precedence over the order request form, but not over the Service Exhibit.

5.4 Service Notices. Notices for disconnection of Service must be submitted to CenturyLink via Email at: BusinessDisconnects@Centurylink.com. Notices of non-renewal for Services must be sent via email to: CenturyLink, Attn.: CenturyLink NoRenew, e-mail: Norenew@centurylink.com. Notices for billing inquiries/disputes or requests for Service Level credits must be submitted to CenturyLink via Customer’s portal at https://www.centurylink.com/business/login/ or via Email at: Care.Inquiry@Centurylink.com. All other routine operational notices will be provided by Customer to its CenturyLink sales representative.

5.5 Access Arbitrage. If CenturyLink determines the number of calls routed by Customer via Access Arbitrage exceeds 11.4% of Customer’s total call volume, CenturyLink will apply to 95% of their high cost minutes an inbound and outbound per minute fee of $0.10 for switched Services and $0.05 per minute for dedicated Services. In addition, CenturyLink may immediately restrict, suspend, or discontinue Service used in connection with Access Arbitrage upon notice of such violation to Customer. “Access Arbitrage” is the methodology used by Customer to exploit or benefit from the difference between the rates for CenturyLink voice Services and the originating or terminating charges imposed by the Local Exchange Carrier, which includes: (i) using switching equipment or a call processing system (such as a prepaid card, calling card, or teleconferencing platform) to segregate and systematically route calls to CenturyLink characterized by a greater discrepancy between the access costs and the price charged by CenturyLink;(ii) routing calls through a call processing system where the percentage of high cost minutes routed to CenturyLink using the Service exceeds 11.4%; (iii) segregating calls within another carrier’s network or a call processing system to systematically route calls to CenturyLink where the access costs exceed the price of long distance service provided by CenturyLink; (iv) transporting intrastate traffic into a different state in order to cause the traffic to be rated by CenturyLink at a lower Interstate rate than would otherwise apply; or (v) any other means to exploit or benefit from the difference between the rates for Services and the originating or terminating access charges imposed by the local exchange carrier.

5.6 Acceptable Use Policy and Use of Service. CenturyLink may also terminate the International IP Voice Service for Cause under this Section where Customer’s use of the International IP Voice Service: (a) is contrary to the AUP, (b) constitutes an impermissible traffic aggregation or Access Arbitrage, (c) avoids Customer’s obligation to pay for communication services, and (d) violates the Use of Service terms or compliance terms. Customer may have obligations under 47 CFR 9.5 relating to 911 if Customer combines the Service with other products creating a VoIP or VoIP-like service that facilitates the transmission of voice services.

5.7 Use of Service. CenturyLink may also terminate Service for Cause under this Section where Customer’s use of the Service: (a) constitutes an impermissible traffic aggregation or Access Arbitrage, (b) avoids Customer’s obligation to pay for communication services, and (c) violates the use of Service terms or compliance terms applicable to the Service. “Cause” means the failure of a party to perform a material obligation under the Agreement, which failure is not remedied: (a) for payment defaults by Customer, within five days of separate written notice from CenturyLink of such default; or (b) for any other material breach, within 30 days after written notice (unless a shorter notice period is identified in a Service Attachment).

5.8 CPNI. CenturyLink is required by law to treat CPNI confidentially. Customer agrees that CenturyLink may share CPNI within its business operations (e.g., wireless, local, long distance, and broadband services divisions), and with businesses acting on CenturyLink’s behalf, to determine if Customer could benefit from the wide variety of CenturyLink products and services, and in its marketing and sales activities. Customer may withdraw its authorization at any time by informing CenturyLink in writing. Customer’s decision regarding CenturyLink’s use of CPNI will not affect the quality of service CenturyLink provides Customer. “CPNI” means Customer Proprietary Network Information, which includes confidential account, usage, and billing-related information about the quantity, technical configuration, type, destination, location, and amount of use of a customer’s telecommunications services. CPNI reflects the telecommunications products, services, and features that a customer subscribes to and the usage of such services, including call detail information appearing in a bill. CPNI does not include a customer’s name, address, or telephone number.

5.9 Conflicts. If a conflict exists among the provisions of the Service Attachments, the order of priority will be as follows: the Service Exhibit, the RSS or ISS, the general terms of the Agreement, SLA, SOW (if any) and Order Form, as applicable, and then any other documents attached or expressly incorporated into the Agreement. “ISS” means CenturyLink’s Information Services Schedule incorporated by this reference and posted at: http://www.centurylink.com/tariffs/clc_info_services.pdf. “RSS” means CenturyLink’s Rates and Services Schedules incorporated by this reference and posted at http://www.centurylink.com/tariffs/fcc_clc_ixc_rss_no_2.pdf for CenturyLink’s International RSS.
