2.3: Competitive Pricing. WilTel may provide on-net, private line POP to POP pricing for substantially similar services within *** of the lowest quote provided to WilTel by Customer, using *** as the control group (the "Carrier Control Group"), ***. The parties agree to review the Carrier Control Group on an as needed basis. The Carrier Control Group may be altered if mutually agreed to by the parties. If the lowest quote for substantially similar services that Customer receives from the Carrier Control Group is more than *** lower than the applicable WilTel's rates, ***, the Customer will give WilTel the opportunity to submit a revised price. If WilTel (1) offers a rate within *** of such lowest quote, (2) Customer's end-user purchases the service, and (3) WilTel's terms and conditions (including technical specifications) are the same as or more advantageous than Customer's alternatives for the same service, then, with respect to *** of the offers ("*** Threshold"), WilTel's services will be selected by Customer. For purposes of determining whether a private line POP to POP service is substantially similar, the parties will consider: (1) type of service, (2) city pair, (3) diversity, (4) protected or unprotected, and (5) term. For the purpose of this Agreement *** of the lowest price shall mean the monthly recurring charges based on the Voice Grade Equivalent/XX xxxxx. WilTel may audit Customer's applicable business records one (1) time per year to ensure Customer's compliance with this Section 2.3. WilTel will give Customer at least ten (10) business days notice prior to any such audit, and Customer shall make available to WilTel during normal business hours all applicable records and personnel necessary for WilTel to perform the audit; provided that Customer may redact certain information that is confidential and instead provide a certification acceptable to WilTel that provides such information necessary for WilTel to verify Customer's compliance with this Section 2.3. Notwithstanding any other provision herein, if complying with the *** Threshold would cause Customer to be in violation of any other agreement(s), the *** Threshold will be reduced to the extent necessary for Customer not to be in violation of such agreement(s); provided that in no event with the *** Threshold be reduced to less than ***.

Article 3. Ordering and Provisioning of Service

3.1

Service Orders.

a.: All Services shall be requested on WilTel' Service Order forms in effect from time to time or on Customer's forms which have been previously accepted in writing by WilTel ("Service Order(s)"). Service Orders shall be transmitted and processed in accordance with the terms and conditions of this Agreement as well as any procedures set out in the applicable Service Schedule for a specific Service. WilTel shall accept any Service Order under this Agreement that complies with the terms and conditions set forth herein, subject to availability and credit approval at the time Customer places such Service Order.
a.: A Service Order is deemed accepted (subject to availability) by WilTel when WilTel' Service Delivery department transmits an electronic Order Confirmation Document ("OCD") to Customer indicating that WilTel is processing Customer's order.
b.: When a Service Order is placed, Customer will designate: (i) a requested start date ("Requested Start Date") for the Service; (ii) the desired term of the Service; (iii) the specific city pairs, if applicable; (iv) the bandwidth, if applicable; and (v) any other information necessary to enable WilTel to provide the Service. WilTel will make reasonable efforts to meet Customer's Requested Start Date. In the event that WilTel is unable to meet Customer's Requested Start Date, WilTel will notify Customer of the date when WilTel believes the Service will be available and Customer's Requested Start Date will be changed to reflect the number of days of delay or advance, as appropriate. Failure of WilTel to deliver by Customer's

***: Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

Requested Start Date shall not constitute a default under this Agreement and WilTel shall not be liable to pay to Customer any penalties or damages for WilTel' failure to meet Customer's Requested Start Date, except for the delay credits set forth in Section 3.4.

d.: Any terms or conditions contained in Customer's acknowledgement or Service Order or elsewhere which conflict with, are different from, or are in addition to, the terms and conditions in this Agreement are hereby objected to by WilTel and shall not constitute part of this Agreement. No action by WilTel (including, without limitation, provision of Services to Customer pursuant to such Service Order) shall be construed as binding or estopping WilTel with respect to such term or condition.

3.2

Turn Up Acknowledgement. WilTel will issue to Customer an electronic notice that Service is available ("Turn Up Acknowledgement" or "TUA"). The TUA will indicate that the relevant Service ordered through WilTel has been tested by WilTel and that the WilTel' Service meets or exceeds the Technical Specifications set forth in the relevant Service Schedule. The TUA will also set forth the date Customer's Service was available for use by Customer and upon which WilTel shall commence charging for the Service, provided that absent Customer's written acknowledgement, in no event will WilTel begin to invoice for the Services prior to the Customer's Requested Start Date ("Circuit Effective Billing Date").

3.3

Service Acceptance. Customer shall be deemed to have accepted Service and WilTel shall begin billing for the Service as of the Circuit Effective Billing Date, provided that, if Customer notifies WilTel' Service Delivery Department in writing within three (3) business days of the Circuit Effective Billing Date that WilTel' Service is in material non-compliance with the applicable Technical Specifications and if, upon investigation, such material non-compliance is not due to Customer fault, then WilTel shall correct the non-compliance and make the appropriate adjustment to Customer's xxxxxxxx under this Agreement. The occurrence of any such non-compliance shall not constitute a default under this Agreement and WilTel shall not be liable to pay to Customer any penalties or damages resulting from any such non-compliance except for delay credits as set forth in Section 3.4, if applicable. Charges for Service begin accruing upon Circuit Effective Billing Date, regardless of whether Customer is actually using the Services, or is ready to test and accept the Services.

3.4

Implementation Intervals Remedies.

a.: It is WilTel's goal to provision WilTel Services within it standard service implementation intervals as set forth in the Schedule applicable to each type of Service. WilTel's standard service implementation intervals apply only to WilTel Private Line, Optical Wave and Metro Access Services and not Third Party Services.
b.: In the event WilTel fails to make Services available within its standard service implementation interval as stated in the applicable Schedule, Customer shall receive a pro-rata credit of the monthly recurring charge for such Service based on the number of days Service is delayed, such credit not to exceed ***. Customer shall not receive such credit and WilTel shall not be liable for any delay, if delay is due to the Customer, Third Party Local Access provider or as a result of a Force Majeure event as defined in Section 8.5 hereof. Notwithstanding anything to the contrary in this Agreement, in no event shall WilTel' failure to deliver William's Service within the periods set forth in the attached Schedules constitute a default under this Agreement.
c.: In the event WilTel fails to make Services available within its standard Service implementation interval as stated in the applicable Schedule Customer may cancel the Service Order for late delivery. Customer shall not have the right to cancel and WilTel shall not be liable for any delay, if delay is due to the Customer, Third Party Local Access provider or as a

result of a Force Majeure event as defined in Section 8.5 hereof. Notwithstanding anything to the contrary in this Agreement, in no event shall William's failure to deliver William's Service within the periods set forth in the attached Schedules constitute a default under this Agreement.

d.

Customer may either exercise its right to a delay credit pursuant to subsection (b) above or exercise it right to cancel the delayed Service pursuant to subsection (c) above but may not exercise both remedies. Customer agrees that the delay credit or the right to termination as set forth above is Customer's sole remedy and WilTel' sole liability in the event of any delay in providing such Service.

e.

Annual Implementation Interval Review. WilTel agrees that it will, upon the request of Customer and no more often than annually, review the actual implementation intervals set forth in the attached Service Schedules, and may adjust installation intervals in accordance with:

i): prevailing market implementation intervals at the time of the review; and
ii): implementation intervals as published by other suppliers, delivering comparable telecommunication services that are substantially similar to the range of service offered by WilTel under this Agreement.

If the parties agree to any such adjustment, such adjustment shall be effective upon written amendment and shall not apply to orders, which have already been submitted by Customer and accepted by WilTel.

3.5: Change of Service Order Date. Customer may request a delay in the Start Date of an order, when WilTel receives the delay request a minimum of *** days prior to the due date and the requested delay does not exceed *** cumulative calendar days from the Service Orders initial Start Date. When Customer has delayed a Service Order for the maximum *** cumulative calendar days, the order may not be delayed again by Customer. Once the maximum *** day delay has been achieved, Customer has the option to (a) accept the billing for the Service Order, or (b) cancel the Service Order and pay the applicable cancellation charges for the facilities ordered. The billing or cancellation is effective on the *** cumulative calendar day of the delay. If Customer elects to accept billing the installation will be completed as soon as reasonably practical after Customer advises WilTel that the installation can be completed.

Article 4. Third Party Local Access Services

4.1: Third Party Local Access Services. WilTel may obtain "Third Party Local Access Service" on behalf of Customer, which is defined as the telecommunications facilities or services connecting a Customer-designated termination point to a point of presence ("POP") designated by WilTel. The term Third Party Local Access Service, as used throughout this Agreement, may include both domestic U.S. and foreign Third Party Local Access Service. Customer shall execute a Letter of Agency, in a form provided by WilTel and agreed to by Customer authorizing WilTel to interact directly with the Third Party Local Access Service provider(s) to obtain the Third Party Local Access Service. Customer shall pay all charges including, without limitation, monthly charges, usage charges, installation charges, non-recurring charges, or applicable termination/cancellation charges, of the Third Party Local Access Service provider(s).
4.2: WilTel' Provisioning, Testing, and Charging for Third Party Local Access Services. For Third Party Local Access Services ordered by WilTel, WilTel shall provision and conduct the initial testing of an interconnection between the WilTel' Service set forth in the Service Order and the Third Party Local Access Service. WilTel shall coordinate the installation of the Third Party Local Access Service with the WilTel' Service. Third Party Local Access Service charges shall accrue at the

then-current tariff rate (or the standard published rate, if there is no tariff rate) of the Third Party Local Access Service provider. If the applicable rate for Third Party Local Access Service is changed by the Third Party Local Access Service provider, such changes will be passed through to, and be borne by, Customer. In the event WilTel' Services are not ready at the same time as the WilTel' ordered Third Party Local Access Service, WilTel will not begin billing Customer for such Third Party Local Access Services until the related WilTel' Services are turned up.

4.3: Customer Ordered Third Party Local Access Service. On a prospective basis beginning with the first order after the Effective Date of this Amendment, where Customer orders a POP to POP circuit and is providing its own Third Party Local Access Services from a vendor who has established entrance facilities in WilTel's POP ("Approved Vendor"), WilTel will use commercially reasonable efforts to include the cost of the dedicated entrance facilities on the Service Order if Customer provides the name of the Approved Vendor in advance in writing. If Customer desires to order Third Party Local Access Services from someone other than an Approved Vendor, Customer must get WilTel's prior written permission, which permission shall not be unreasonably withheld, conditioned or delayed, and WilTel will include the cost of the dedicated entrance facilities on the Service Order. In any such event, the Third Party Local Access Service provider shall directly xxxx Customer for such Services. If WilTel provides the Third Party Local Access Services, Customer will not be required to pay a separate dedicated entrance facility charge to WilTel. Customer shall ensure that the Customer-ordered Third Party Local Access Services are turned up at the same time as the WilTel's Services. If the Customer-ordered Third Party Local Access Services are not ready as of the Circuit Effective Billing Date, Customer shall nonetheless be obligated to pay for WilTel's Services as of the Circuit Effective Billing Date. Except for this Section 4.3, with respect to dedicated entrance facility charges, Article 4 of the Agreement shall have no application to the provision of Metro Private Line Services under Schedule 13.

Article 5. Payment Terms and Charges

5.1: Monthly Billing. WilTel provides and charges for Service on a monthly basis in U.S. dollars. Usage sensitive charges are billed in arrears and fixed monthly recurring charges, if any, are billed one (1) month in advance. Unless WilTel requires payment in advance, charges for installation charges and other non-recurring charges shall be billed in WilTel' next invoice cycle and are due and payable in accordance with section 5.2 below.
5.2: Due Date and Invoice. All amounts stated on each monthly invoice are due and payable in U.S. dollars within thirty (30) calendar days of the date of the receipt of the invoice ("Due Date"). Customer agrees to accept delivery of such invoice electronically via e-mail. Customer agrees to remit payment via Automated Clearinghouse ("ACH") or wire transfer to Xxxxxxxx Communications, LLC in care of: Bank of Oklahoma, Tulsa, OK, ABA # 000000000, Account # 010649443 (Xxxxxxxx Communications, LLC), or such other bank or account as WilTel may in writing direct Customer to remit payment. In the event Customer fails to make full payment of undisputed amounts by the Due Date, Customer shall also pay a late fee in the amount of the lesser of (i) one and one-half percent (1¹/2%) per month or (ii) the maximum lawful monthly rate under applicable state law, of the unpaid balance which amount shall accrue from the date of the invoice. Customer acknowledges and understands that all charges are computed exclusive of any Additional Charges (as defined in Section 5.8(a)). Such Additional Charges shall be paid by Customer in addition to all other charges provided for herein.
5.3: Adjustments. WilTel may make billing adjustments for WilTel Services for one-hundred-eighty (180) calendar days after the Due Date or after the date Service is rendered, whichever is later. WilTel may make billing adjustments for Third Party Services for a period of two (2) years.
5.4: Intentionally Omitted.

5.5

Billing Disputes. If Customer in good faith disputes any portion of an invoice it must pay the undisputed amount of the invoice on or before its Due Date and provide written notice to WilTel of the billing dispute within sixty (60) calendar days thereafter. Such notice must include documentation substantiating the dispute. Customer's failure to notify WilTel, of a dispute shall be deemed to be Customer's acceptance of such charges. The parties will make a good faith effort to resolve billing disputes as expeditiously as possible. If a dispute is resolved in favor of Customer, Customer shall receive a credit on their next xxxx for the amount determined to be due, if not, the additional sum due shall be payable no later than thirty (30) days following a determination that it is due.

5.6

Validation of Credit. WilTel reserves the right to determine the creditworthiness of Customer through available verification procedures or sources and Customer hereby consents to WilTel obtaining credit information regarding the Customer, its owners and affiliates.

5.7

Notwithstanding the foregoing, WilTel will not exercise its rights to demand reasonable assurance of payment from Customer until less than *** is remaining in the *** Prepayment.
b.: A material adverse change in Customer's creditworthiness shall include, but not limited to: (i) Customer's default of its obligations to WilTel under this Agreement; (ii) failure of Customer to make full payment of charges due hereunder on or before the Due Date on two (2) or more occasions during any period of twelve (12) or fewer months; (iii) acquisition of Customer (whether in whole or by majority or controlling interest) by an entity which is insolvent or which is subject to insolvency proceedings, or which owes past due amounts to WilTel or any WilTel affiliate, or which is a materially greater credit risk than Customer; or (iv) the legal insolvency of Customer.
c.: If Customer's financial statements are not public information or have not otherwise been made available to WilTel, then, upon WilTel' request, Customer shall provide its most current audited and unaudited financial statements.
d.: If Customer has not provided WilTel with (i) its financial statements within five (5) calendar days of WilTel' request therefore and Customer's financial statements are not public information or (ii) in the event of a WilTel demand for assurance of payment, assurance satisfactory to WilTel within five (5) calendar days of WilTel' notice of demand for such assurance, then, in addition to any other remedies available to WilTel, WilTel shall have the option, in its sole discretion, to exercise one or more of the following remedies: (x) cause the start of any Service described in any previously executed Service Order to be delayed pending

5.8

Charges for Services. Except for monthly recurring charges set forth on the Rate Sheet or the applicable Quote,, all charges for Services shall be as set forth in this Agreement and may be established on an individual case basis as contemplated herein and shall be those in effect as of the date WilTel accepts the Service Order unless the charges are otherwise specifically set forth in attached Service Schedules. Customer shall be liable for all charges (recurring and non-recurring) for Services provided by WilTel and by Third Party Providers. Additionally, Customer shall incur charges in those circumstances in which extraordinary costs and expenses are generated by Customer and reasonably incurred by WilTel beyond those normally associated with the Services, including but not limited to, the following: (a) Customer's request to expedite Service availability to a date earlier than WilTel' published installation interval or a previously accepted start date; (b) Service redesign or other activity occasioned by receipt of inaccurate information from Customer; (c) reinstallation charges following any suspension of the Service for cause by WilTel; and (d) Customer's request for use of routes or facilities other than those selected by WilTel for provision of the Service.

For those telecommunication Services identified in the attached Service Schedules, WilTel will provide Customer with a schedule that sets forth monthly recurring rates and charges for the Services (the "Rate Sheet"). WilTel will update the Rate Sheet quarterly. The monthly recurring rates and charges set forth in the Rate Sheet will apply for the requested Service ordered by Customer and accepted by WilTel, unless the parties agree to different rates and charges, which will be determined on an individual case basis ("ICB"). In any event the applicable rates and charges will be set forth on Customer's Service Order.

5.10

Credit. Concurrent with the execution of this Agreement, the parties are executing a Settlement Agreement, which provides that WilTel will submit to the issuing bank a written notice canceling Customer's existing *** Letter of Credit ("Letter of Credit") issued in favor of WilTel. On the same day Customer wire transfers WilTel *** as a prepayment for Services (the "*** Prepayment"), WilTel will return the Letter of credit to the issuing bank together with a letter unconditionally and immediately canceling the Letter of Credit, causing the *** to be returned to Customer. In the first billing month after the *** Prepayment is received and in each month thereafter, WilTel will apply a credit equal to the monthly recurring rates and charges for Services invoiced to Customer from WilTel, until the *** Prepayment is fully used.

5.11

Customer agrees to pay any such Additional Charges and hold WilTel harmless from any liability or expense associated with such Additional Charges.
b.: If Customer has been granted a tax exemption for taxes in a given jurisdiction, then WilTel shall not xxxx Customer for such taxes if Customer provides WilTel with written verification of such tax exemption acceptable to WilTel and properly issued by the relevant taxing jurisdiction.

***: Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

to any universal service program if Customer provides WilTel with written verification or exemption certificate, acceptable to WilTel for the relevant jurisdiction, that the Service will be resold by Customer and that the revenues from such resale shall be subject to the universal service program's contribution requirements. If any jurisdiction, in conjunction with any universal service program, assesses any charges against, or seeks any contributions from, WilTel in connection with any of the Service provided hereunder, Customer shall indemnify WilTel against any such assessments or contributions.

Article 6. Suspension and Termination

6.1

Suspension Of Service.

a.: In the event payment in full is not received from Customer on or before the Due Date, WilTel shall have the right: (i) upon providing a minimum of five (5) business days written notice (the "Suspension Notice"), to suspend or block, at any time after such Suspension Notice, all or any portion of all the Services then being provided to Customer; and (ii) to immediately place any pending Service Orders on hold, and to decline to accept any new Service Orders or other requests from Customer to provide Service commencing on the day that WilTel issues the Suspension Notice to Customer. If WilTel receives the entire past due amount within the five (5) business days notice period, then Customer's Service shall not be suspended. WilTel may continue such suspension until such time as Customer has paid in full all charges then due, including any reinstallation charges and/or late fees as specified herein. Following such payment, WilTel shall reinstate Customer's Services subject to WilTel' Right to Assurance as provided above in Section 5.6.
b.: Suspension of Services as set forth in this Section shall not affect Customer's obligation to pay for the Services.

6.2

Termination of Service.

a.: In addition to its other termination rights hereunder, and with respect to all Services, either party may immediately disconnect any Services in whole or in part if WilTel determines that such Services violate any law, statute, or ordinance, including the Communication Act of 1934 (as amended), or that the imposition of any statute, or promulgation of any rule, regulation, or order of the Federal Communications Commission or other governing body makes WilTel' performance under this Agreement commercially impracticable.
b.: Except where Customer is in default, WilTel recognizes that, upon the expiration or termination of this Agreement or any Service as defined in Section 2.1 and 2.2, a successor vendor may be retained to provide replacement telecommunication service to Customer. During Customer's migration to the successor vendor following the expiration or termination of this Agreement or a Service, WilTel shall reasonably cooperate with Customer and the successor vendor in the development and execution of a plan for the orderly and efficient transition to the successor vendor.

6.3

Termination of Agreement.

a.: Termination of Agreement For Cause. Except for an event of non-payment by Customer hereunder which is addressed in subsection (b) below, either party may terminate this Agreement if the other is in default of any material obligation contained herein, which default has not been cured within thirty (30) calendar days following the receipt of notice of such default setting forth the specifics of such default. The failure of any particular Service or Services to comply with the Technical Specifications set forth individually for each Service in the attached Service Schedules shall not be deemed a default by WilTel, but may obligate WilTel to provide Customer with Outage Credits, if applicable, under the relevant Service

Schedule. Such Outage Credits and right to terminate for excessive outages, if applicable, shall be Customer's sole and exclusive remedy for any failure of the Services. Termination of this Agreement for cause does not relieve Customer of any obligations to pay WilTel for charges accrued for Service which has been furnished up to the time of termination nor does it relieve the Customer of all applicable cancellation and/or disconnection charges.

b.: Termination of Agreement For Non-payment. In the event any amount payable by Customer has not been received in full by WilTel on or before the Due Date (except for amounts disputed by Customer in accordance with Section 5.4 Billing Disputes), WilTel shall have the right to terminate this Agreement ten (10) calendar days' written notice to the Customer. Termination of this Agreement pursuant to this subsection shall not relieve Customer of any obligations to pay WilTel for charges accrued for Service which has been furnished up to the time of termination nor does it relieve the Customer of all applicable cancellation and/or disconnection charges. The remedies available to WilTel for any such termination of the Agreement for non-payment shall be to collect from Customer all amounts due under this Agreement including but not limited to all applicable Early Termination, cancellation and/or disconnection charges.
c.: Termination Due To Government Action. Notwithstanding the foregoing, and upon written notice consistent with the mandate put forth by the applicable governmental authority or commission, to the other party, either Customer or WilTel shall have the right, without incurring an Early Termination Charge or other liability to the other party, to immediately disconnect the affected portion of any Service, if WilTel is prohibited by governmental authority from furnishing or Customer is prohibited from using such portion, or if any material rate or term contained herein and relevant to the affected portion of any Service is substantially changed by order of the highest court of competent jurisdiction to adjudicate the matter, the Federal Communications Commission, or other local, state, federal, or foreign government authority.

6.4

Termination Charges.

a.: Early Termination Charge. If Customer desires to disconnect any Service after installation, Customer may do so by providing written notification to WilTel thereof thirty (30) days in advance of the effective date of the disconnection. In the event of such disconnection, Customer shall pay to WilTel an "Early Termination Charge" in an amount equal to the monthly recurring charge for such disconnected Service multiplied by the number of months in the relevant Service Term, less the charges for such Service actually paid by Customer through the effective date of the disconnection plus any non-recurring payments not yet paid by Customer together with any termination liability associated with Third Party Local Access Service or any other Third Party Service.
b.

I. Portability. Provided that Customer is in compliance with the terms and conditions of the Agreement, Customer shall have the option to disconnect a circuit wholly on WilTel's owned and operated network prior to the completion of its minimum service term and order one or more new circuits also wholly on WilTel's owned and operated network as a replacement, subject to availability, without incurring the Early Termination Charge set forth above. For purposes of this Agreement, WilTel's owned and operated network will include facilities leased to WilTel under an IRU agreement. The replacement circuit(s) must be for the same or greater remaining *** as the circuit being replaced and the replacement circuit must be ordered by Customer within *** days after the date on which Customer provides WilTel with written notice of termination. The value of the circuits listed on Exhibit A shall be calculated after the original circuit terms have been decreased to 6 months in accordance with

***: Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

Section 2.2(b) above. The minimum circuit term for replacement circuit(s) will be *** months. If Customer exercises this portability option, Customer will be liable for, if applicable: (i) all termination liability charges for Third Party Local Access Services or any other Third Party Services or provided facilities that are impacted by the replacement of the circuit; (ii) installation charges due to WilTel as set forth in the attached Service Schedules; and (iii) any one (1) time Third Party Local Access Service charges and the new monthly recurring Third Party Local Access Service charges.

II. Service Term Adjustment. After any Existing Circuit has been in effect for a period of at least twelve (12) months and provided that Customer is in compliance with the terms and conditions of the Agreement, Customer shall have the option to adjust the initial Service Term to a period equal to six months ("Adjusted Service Term"). The Adjusted Service Term applicable to an Existing Circuit(s) will start concurrently with the turn up and acceptance date of the new circuit or circuit(s). Customer shall effectuate the adjustment by placing a Service Order for a new circuit(s) wholly on WilTel' owned and operated network, subject to availability. For purposes of this Agreement WilTel owned and operated network will include facilities leased to WilTel under an IRU agreement. The new circuit(s) must be for: a) a minimum Service Term of twelve months, b) the same or greater total Service Term value, and c) the same or greater monthly recurring charge as the adjusted Existing Circuit(s). If Customer exercises this Service Term adjustment option, it will only be applicable to the inter-exchange portion of the adjusted circuit that is wholly on WilTel owned and operated network. Customer remains liable for Third Party charges including, without limitation, any Third Party local access termination charges, which will be passed through to the Customer. The new circuits shall be subject to ordering and provisioning as provided in Article 3 herein. For example: If Customer has (3) DS-3s which have been in effect for at least 12 months with 24 months remaining on the Service Term and the remaining Service Term value of the DS-3s is $60,000, Customer may adjust the Service Term of those DS-3s to 6 months by placing a Service Order and by accepting Service of a circuit or circuits pursuant to Section 3.3 herein, that have: 1) a twelve month term and 2) a total MRC greater than or equal to those DS-3s and 3) a Service Term value greater than or equal to $60,000. The Service Term value shall be determined by multiplying the monthly recurring charge by the number of months remaining in the original Service Term for the applicable Existing Circuit(s).

c.: Service Migration. If customer wishes to upgrade to a higher bandwidth of service, Customer has forty-five (45) days from the turnup of the higher bandwidth circuit in which to groom existing circuits onto the higher bandwidth of service. During this forty-five (45) day period, the Customer will not be billed for the higher bandwidth. After the forty-five (45) day period from circuit turnup, billing for the higher bandwidth circuit commences, whether or not if the existing circuits have been disconnected and groomed onto the larger bandwidth.
d.: Technology Migration. If, as a result of technological changes or improvements, Customer's services provided under the Agreement may be changed or improved upon, WilTel agrees to allow Customer to migrate to new services as it applies under Section 6.4 (b) Portability.
f.: Liquidated Damages. Customer agrees that the actual damages in the event of a disconnection pursuant to this Section 6.4 would be difficult or impossible to ascertain, and that the Early Termination Charges, if any, in this Section 6.4 are intended to establish liquidated damages only and are not intended as penalties.

Article 7. Limitation of Liability

f.: The indemnified Party shall promptly notify the indemnifying Party in writing of any claims, which are subject to the terms of this Section 8.4. The indemnified Party shall have the right at its own expense to appoint its own counsel who shall be entitled to participate in any settlement negotiations or litigation regarding any matter for which it is entitled to be indemnified hereunder.

Proprietary Information.

a.: WilTel and Customer understand and agree that the terms and conditions of this Agreement and all documents referenced herein (including invoices to Customer for Services provided hereunder) are confidential as between Customer and WilTel.

b.: In addition to the matters covered under clause a. above, when confidential information is furnished in a tangible form by one party to the other, the disclosing party shall xxxx the information in a manner to indicate that it is considered confidential. When information deemed to be confidential is provided orally, the disclosing party shall, at the time of disclosure, clearly identify the information as being confidential.

All information identified as confidential pursuant to this clause b. shall not be disclosed by the receiving party to any third party without the written consent of the disclosing party, except as provided in Section 8.6(c) below.
c.: The party to whom confidential information is disclosed shall have no obligation to preserve the confidential nature of such information if it: (i) was previously known to such party free of any obligation to keep it confidential; (ii) is or becomes publicly available by other than unauthorized disclosure; (iii) is developed by or on behalf of such party independent of any information furnished under this Agreement; or (iv) is received from a third party whose disclosure does not violate any confidentiality obligation.

8.7

Representations.

a.: Unless WilTel specifically offers an intrastate Service as set forth in an applicable Service Schedule, WilTel requires that more than ten percent (10%) of the transmissions on each circuit shall be interstate transmissions or foreign transmissions as those terms are defined in 47 U.S.C. Sections 153(17) and 153(22). WilTel and its affiliates shall not be obligated to make available intrastate Service, e.g., any Service on a circuit with end points within a single state or service on a circuit which originates/terminates at points both of which are situated within a single state unless Customer represents in writing that such interexchange Service or circuits shall be used to carry more than ten percent (10%) interstate or foreign telecommunications. If it is determined at any time that such Service or circuit is subject to regulation by a U.S. State regulatory agency, the Service or circuit may be provided by WilTel or its affiliates pursuant to applicable state laws, regulations and applicable tariffs, or WilTel and its affiliates may discontinue provision of the affected Service or circuit.

b.

Use of Services.

(i): Customer represents that it is a telecommunications carrier under the Communications Act of 1934, as amended or under the laws of the jurisdiction where it operates. The parties do not contemplate, as of the Effective Date, the filing of any tariff as to the Services provided under this Agreement, however, in the event that due to a court or agency ruling, or change in applicable law or regulation, this Agreement becomes subject to a requirement of an FCC tariff, then WilTel will file a contract tariff with the FCC incorporating all of the material terms and conditions of this Agreement, including pricing, and the parties agree to abide by that contract tariff. Service may also be subject to tariffs in jurisdictions outside of the United States, and WilTel' reserves the right to make its provision of Services subject to such tariff terms. Customer represents that it has taken all actions required by the FCC to operate as a telecommunications carrier under the Communications Act of 1934, as amended. Customer may engage in resale of international private lines for the provision of a switched, basic telecommunication service only upon authorization from the FCC under Section 214 of the Communications Act of 1934, as amended, and provided that the private line is used only (i) on a route where Customer exchanges switched traffic with a foreign carrier that the FCC has determined lacks market power; or (ii) on any route for with the FCC has authorized the provision of switched services over international private lines. Service shall not be used for any unlawful purpose.
(i): Customer is responsible for ensuring that it and its customers comply with WilTel's Acceptable Use Policy ("AUP") and Customer agrees to be bound by the AUP as set forth in Exhibit B. Any material violation of the AUP shall constitute a breach of this Agreement.

c.: Customer Facilities. Customer has sole responsibility for installation, testing and operation of facilities, services and equipment ("Customer Facilities") other than those specifically provided by WilTel as part of the Services as described in a Service Order. In no event will the untimely installation or non-operation of Customer Facilities relieve Customer of its obligation to pay charges for the Services after Customer's acceptance or deemed acceptance.
d.: Universal Service Exemption. During the Term or Renewal Term of this Agreement, Customer shall provide WilTel, on a semiannual basis, a universal service exemption certificate within thirty (30) days of the Customer's filing of the universal service filing made with the appropriate federal agency, evidencing that the Customer is required to contribute to the federal Universal Service Fund. Customer agrees that failure to provide such an exemption authorizes WilTel to begin billing Customer prospectively for Universal Service Fund contributions pursuant to the applicable contribution factor (revised quarterly), plus an administrative charge of one percent (1%).

8.8: Title to Equipment. This Agreement shall not, and shall not be deemed to, convey to the other party title of any kind to any of the transmission facilities, digital encoder/decoders, telephone lines, microwave facilities or other facilities utilized in connection with the Services.
8.9: Notices. All legal notices to be sent to a party pursuant to this Agreement shall be in writing and deemed to be effective upon (i) personal delivery, (ii) three (3) business days after mailing certified mail return receipt requested if mailed within the domestic U.S., or (iii) one day after

Exhibit B

Service Delivery Process and Acceptable Use Policy

Customer Service
Service Delivery Processes

Service Orders and Provisioning of Circuits

Data Circuits and Voice Grade Dedicated Access Line Circuits: Service Orders. A Customer's request for service shall be made on WilTel' Service Order forms in effect from time to time or on Customer's forms which have previously been accepted in writing by WilTel ("Service Order(s)"). Each Service Order shall reference the written agreement ("Agreement") between WilTel and the Customer regarding the provision of telecommunication service ("Service") and the Customer's Agreement number. WilTel will accept any Service Order under the Customer's Agreement that comports with the terms and conditions set forth in such Customer's Agreement and as otherwise set forth herein, subject to availability and credit approval at the time Customer places such Service Order.

Requested Start Date. When a Service Order is placed, Customer will designate: (i) a requested start date ("Requested Start Date") for the Service; (ii) the desired term of the Service; (iii) the specific city pairs; (iv) the applicable bandwidth; (v) whether Customer or WilTel will be obtaining Third Party Local Access Services; and (vi) any other information necessary for WilTel to provide the Service. WilTel will make reasonable efforts to meet Customer's Requested Start Date. In the event that WilTel is unable to meet Customer's Requested Start Date, WilTel will notify Customer of the date when WilTel believes the Service will be available and Customer's Requested Start Date will be changed to reflect the number of days of delay or advance, as appropriate.

Implementation Intervals. WilTel' standard service implementation intervals for each of the Services provided by WilTel on its own network are set forth individually for each Service in the respective Service Schedules attached to the Customer's Agreement. A Service Order is deemed accepted by WilTel when WilTel' Service Delivery department transmits an electronic Order Confirmation Document ("OCD") to Customer which contains a WilTel' circuit identification number. Service implementation intervals for Services provided either partially or wholly off of WilTel' owned and operated network, shall be determined on an individual case basis and shall be subject to service-specific terms and conditions of the of the provider of the third party services, such as the service level parameters and related warranties, if any, pricing, surcharges, outage credits, required commitments and termination liability. WilTel shall make reasonable efforts to provide Services within its standard service implementation interval or on Customer's Requested Start Date. Failure of WilTel to deliver within such interval or by such Requested Start Date shall not constitute a default under Customer's Agreement and WilTel shall not be liable to pay to Customer any penalties or damages for WilTel' failure to meet such standard service implementation intervals or Requested Start Date.

Turn Up Acknowledgement. WilTel will issue to Customer an electronic notice that Service is available ("Turn Up Acknowledgement" or "TUA"). The TUA will indicate that the relevant Service has been tested by WilTel and that the WilTel' provided portion of the service meets or exceeds the Technical Specifications set forth in the relevant Service Schedule and whether any related third party Service is currently available. The TUA will also set forth the date Customer's Service will be ready for use by Customer and upon which WilTel shall commence charging for the Service ("Circuit Effective Billing Date"). Customer shall be deemed to have accepted Service and WilTel shall begin billing for the Service as of the Circuit Effective Billing Date, provided that, if Customer notifies WilTel' Service Delivery Department in writing within three (3) business days of the Circuit Effective Billing Date that WilTel' Service is in material non-compliance with the applicable Technical Specifications and if, upon investigation, such material non-compliance is due solely to WilTel' fault, then WilTel shall correct the

B-1

non-compliance and make the appropriate adjustment to Customer's xxxxxxxx under the Customer's Agreement. The occurrence of any such non-compliance shall not constitute a default under the Customer's Agreement and WilTel shall not be liable to pay to Customer any penalties or damages resulting from any such non-compliance. Charges for Service begin accruing upon Circuit Effective Billing Date, regardless of whether Customer is actually using the Service, or is ready to test and accept the Service.

Non-Recurring and Enhanced Service Charges.

The following is a list of the most common circumstances under which WilTel assesses a separate, non-recurring charge in connection with the service being provided.

New Order Installation. Installation Charges apply when WilTel provides new or additional Interexchange Service ("IXC") or when WilTel obtains new or additional Third Party Local Access (including feature group service) on the Customer's behalf. WilTel will charge the Customer for IXC installation and for issuing an Access Service Request ("ASR") to the Third Party Local Access provider, i.e., Local Exchange Carrier ("LEC") or by-pass carrier, i.e., Competitive Access Provider ("CAP"). All Third Party Local Access provider charges are billed to the Customer. This charge applies to both data and voice services.

Change of Service Order Charge. If Customer requests a modification to the information contained in a Service Order (other than a Change of Service Date) prior to completion of installation of the Service, Customer may incur a Change of Service Order Charge. No charge will be incurred if the change is administrative in nature (i.e. billing address, contact information, etc.). If the change is requested prior to facilities being slotted, a Change of Service Order, Pre-Engineering charge will apply. If the change is requested after facilities have been slotted, a Change of Service Order, Post-Engineering charge shall apply. A charge will be incurred if the administrative change relates to Third Party Local Access for which WilTel is acting as agent. This charge applies to both data and voice services.

Order Cancellation Charge. If Customer desires to cancel a Service Order prior to installation or acceptance of the Service, Customer will incur a Cancellation Charge. If Customer cancels the Service Order prior to facilities being slotted, Customer will be assessed a Pre-Engineering Cancellation Charge. If Customer cancels the Service Order after facilities have been slotted, Customer will be assessed a Post-Engineering Cancellation Charge. In addition to the Cancellation Charge, Customer will be required to reimburse WilTel for any cancellation charges relating to Third Party Local Access or other third party service for which WilTel is acting as agent on behalf of Customer. This charge applies to both data and voice services.

ASR Special Access. Third Party Local Access providers supply standard service at tariffed rates. Any local access request that the Third Party Local Access provider defines as "special" will be subject to the ASR Special Access charges. This charge is an administrative charge for handling the special access request.

The type of virtual circuit selected by the Customer does not determine the price. Pricing for virtual circuits is determined based on the Class of Service (CoS). Three Classes of Service are offered by WilTel: Constant Bit Rate (CBR) and Variable Bit Rate^{non real time} (VBR^nrt) and Unspecified Bit Rate (UBR). CoS charges are stated in Committed Information Rates (CIR) which are stated in Megabit per second (Mbps) increments for one-way (Simplex) VCCs or VPCs. CIR increments are available in 1 Mbps increments up to 40 Mbps for DS3 ports, 5 Mbps increments up to 150 Mpbs for OC3 ports and 25 Mbps increments up to 600 Mbps for OC12 ports. Monthly recurring charges for Bandwidth are set forth on the Service Order.

2.4

ATM Flex-UNI. ATM Flex-UNI allows Customers, expecting to outgrow their initial physical port size within the first twelve (12) months of their Service, a migration path to larger Permanent Virtual Circuits (PVCs) without requiring an upgrade of their hardware.

a.: OC3 Ordering Increments. Customer can order PVCs in one-megabyte increments starting with one (1) megabytes up to nineteen (19) megabytes for an OC3 physical port. Once

Customer needs a twenty (20) megabyte PVC, Customer must revert to the standard OC3 port pricing regardless of the time remaining on the twelve (12) month period.

b.: OC12 Ordering Increments. Customer can order PVCs in five-megabyte increments starting with five (5) megabytes up to seventy (70) megabytes for an OC12 physical port. Once Customer needs a 75-megabyte PVC, Customer must revert to the standard OC12 port pricing regardless of the time remaining on the twelve (12) month period.
c.: ATM Flex UNI Term Commitment. Before ATM Flex-UNI Service will be allowed, Customer must collocate with WilTel' POP and commit to a three (3) year term for the Service. Customer will receive the reduced ATM Flex-UNI rate for the first twelve (12) months of the circuit. Customer will be charged WilTel' standard ATM rate for the port, (i) if Customer exceeds the ATM Flex-UNI capacity during the first twelve (12) months of Service; or (ii) beginning the 13^th month of the circuit, whichever is sooner.
d.: Monthly Recurring Charges. ATM Flex-UNI pricing is based on flat monthly fee assessed per node, which includes a flat port charge based on the port connection speed, a charge for each PVC's CIR going out from the port, and local access. ATM Flex-UNI is priced simplex, meaning that a PVC's CIR is priced for both the ingress and egress CIR. Monthly recurring charges for ATM Flex-UNI pricing is set forth on the Service Order.

Section 3. Non-Recurring Rates and Charges

3.1: UNI Port and ATM Flex-UNI Connections. Non-recurring charges may be incurred for the Port, VCC or VPC connections. Non-recurring Charges are set forth below in Table C.4.

Schedule 15

Private Line Qualities of Service Schedule

This Service Schedule is a schedule to and a part of that Amended and Restated Master Services Agreement No. ("MSA") by and between Xxxxxxxx Communications, LLC ("Xxxxxxxx"), and Customer.

Section 1. Private Line Qualities of Service

1.1

Service Description. Xxxxxxxx' Private Line Qualities of Service ("PLQoS") provides domestic DS-3 and Optical SONET (OC-N) circuits which are specifically dedicated to Customer's use between two (2) points specified by the parties in a Service Order and meeting the technical requirements as defined below in Section 5, Technical Specifications for Private Line Qualities of Service. In addition, PLQoS includes only those circuits where the entire circuit is located solely upon the Xxxxxxxx' owned and operated network and both end points of such circuit originate and terminate at a QoS City as set forth below. Xxxxxxxx' Private Line Qualities of Service includes the four (4) levels of Service set forth below.

a.: Platinum. Platinum PLQoS is a protected Xxxxxxxx' Service, offering maximum availability and geographically diverse protection paths. The time it takes for the Xxxxxxxx' Platinum PLQoS to switch paths in the event of a fiber cut or electronic failure ("Switch Time") is between twenty (20) and one hundred eighty (180) milliseconds. Availability for Platinum PLQoS is 100.00%, excluding Switch Time.
b.: Gold. Gold PLQoS is a protected Xxxxxxxx' Service, offering superior availability and geographically diverse protection paths. The Switch Time for Xxxxxxxx' Gold PLQoS is between two hundred (200) milliseconds and two (2) seconds. Availability for Gold PLQoS is 99.997%, excluding Switch Time.
c.: Silver. Silver PLQoS is an unprotected Xxxxxxxx' Service but offers high availability. Xxxxxxxx' Silver PLQoS offers no fiber or electronic diversity. Availability for Silver PLQoS is 99.5%.
d.: Bronze. Bronze PLQoS is a restorable Xxxxxxxx' Service, which can be preempted when capacity is needed for Platinum or Gold PLQoS. If Bronze PLQoS is preempted, the Service will be restored when excess capacity becomes available. Bronze PLQoS is offered as a Service level objective and therefore no Outage Credits will apply. Xxxxxxxx' Availability objective for Bronze PLQoS is 99.00%.

Section 2. Recurring Rates and Charges

2.1: Monthly Recurring Rates. WilTel will provide Customer with a Rate Sheet for this Service. Charges for Services wholly on WilTel's owned and operated network, which originate and terminate in a QoS City are set forth in applicable Service Order, but will not exceed the rates set forth in the Rate Sheet. Pricing contained in Quotes but not yet included in a Service Order are valid only for thirty (30) days. The monthly recurring charge ("MRC") for any Service is firm for the term reflected on the related Service Order. Pricing for any Service not on WilTel's network will be determined on an individual case basis and set forth on Customer's Service Order. WilTel has select cities available for provisioning of the PLQoS Service. WilTel may add new PLQoS Cities, which will be listed on the WilTel's Customer Service Website at xxxx://xxx.XxxXxxxxxxxxxxxxxxxx.xxx/xxxxxxx/xxxxxxxx-xxxxxxx/xxxxxxx-xxxxxx.xxxx. A list of the select cities including the levels of Service available in each city is also available upon request. Gold PLQoS is the standard upon which other PLQoS Services are based. Platinum PLQoS is a

premium Service above and beyond the Gold PLQoS. Silver PLQoS is discounted when compared to Gold PLQoS, and Bronze PLQoS is the most economical PLQoS.

Section 3. Non-Recurring Rates and Charges

3.1: Non-Recurring Charges. Non-Recurring Charges may be incurred for Private Line connections. Non-Recurring Charges are set forth in Table A.3 below.

3.3: Miscellaneous. Customer should be aware that from time to time, third-party charges are levied to Xxxxxxxx after submission of the original Service Order from Customer. Xxxxxxxx may be obligated to pass these charges to Customer. Xxxxxxxx will inform Customer of any such charges before the charges are passed to Customer. Xxxxxxxx cannot commit that all charges related to any requested Service will always be on the original Service Order.
3.4: Non-Recurring Pricing. Pricing for Non-Recurring Private Line Quality of Service charges shall be as set forth in this Section 3 and are subject to change upon thirty (30) calendar days' written or electronic notice by Xxxxxxxx to Customer. Price changes shall only be effective on a going-forward basis and shall not apply to Service Orders placed by Customer and accepted by Xxxxxxxx prior to the effective date of the respective price change.

Section 4. Outage Credits

4.1: Outage Credits. Customer acknowledges the possibility of an unscheduled period of time during which Xxxxxxxx PLQoS Service fails to conform to the Technical Specifications below ("Outage"). An Outage shall begin upon the earlier of Xxxxxxxx' actual knowledge of the Outage or Xxxxxxxx' receipt of Customer's notice of such Outage. The Customer shall also provide Xxxxxxxx a written request for the Outage Credit reasonably identifying the Outage. Such request shall indicate the Technical Specification to which Customer claims the Service has failed to conform and shall include supporting documentation evidencing that the Service has failed to comply with the applicable Technical Specifications. In the event of an Outage, Customer shall be entitled to a credit ("Outage Credit") pursuant to this Schedule upon Xxxxxxxx' receipt of Customer's written request for such Outage Credit. The amount of the Outage Credit for Xxxxxxxx' PLQoS Service will be an amount equal to the Outage Credit percentages, set forth in Table A.5a and A.5b below, of the monthly recurring charges for the affected circuit(s) (as stated on the applicable Service Order) when Xxxxxxxx Service does not conform to the Technical Specifications on a monthly basis.

***: Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

Bronze PLQoS is offered only as a Xxxxxxxx' Service objective and therefore Customer will not receive Outage Credits for the Bronze PLQoS service level. If the Xxxxxxxx PLQoS Service fails to conform for the next consecutive month to the same Technical Specifications as in the prior month, the Customer shall be entitled to receive the next percentage level of the Outage Credits for the affected circuits. After any month in which a specific variable of the Technical Specifications for the Service is corrected from its prior non-conformance, the Outage Credit percentage for that specific variable will be reset at month one (1). Outage Credits shall never exceed 100.00% of the monthly recurring charge ("MRC") for a circuit. If in any month the Xxxxxxxx Service fails to conform to the Technical Specifications of Network Availability and one of the other Technical Specifications, Customer shall be awarded the higher Outage Credit amount.

a.: Network Availability. EXAMPLE 1: Assumption: Customer purchases Platinum PLQoS. If, in the first (1^st) month, the average Availability of all Platinum PLQoS services ordered by Customer is less than 100.00%, excluding Switch Time, Customer would receive 100.00% of the MRC of each individual circuit which did not meet 100.00% Availability. If, in the second (2^nd) consecutive month, the average Availability of all Platinum PLQoS services ordered by Customer is less than 100.00%, excluding Switch Time, Customer would receive 100.00% of the MRC of each individual circuit which did not meet 100.00% Availability. EXAMPLE 2: Assumption: Customer purchases Silver PLQoS. If, in the first (1^st) month, the average Availability of all Silver PLQoS services ordered by Customer is less than 99.5%, excluding Switch Time, Customer would receive 10% of the MRC for each individual circuit which did not meet 99.5% Availability. If, in the second (2^nd) consecutive month, the average Availability of all Silver PLQoS services ordered by Customer is less than 99.5%, excluding switching times, Customer would receive 15% of the MRC for each individual circuit which did not meet 99.5% Availability. If, in the third (3^rd) month, the average Availability of all Silver PLQoS services ordered by Customer is greater than or equal to 99.5%, excluding switching times, Customer would not receive a credit on any circuits and the next month that the average Availability of all Silver PLQoS services ordered does not meet 99.5% Customer would receive 10% of the MRC of each individual circuit which did not meet 99.5% Availability.

	3^rd Consecutive month of failure to meet applicable Availability standard	20% of the Monthly Recurring Charge for the affected circuits
	4^th Consecutive month of failure to meet applicable Availability standard	25% of the Monthly Recurring Charge for the affected circuits
	5^th Consecutive month of failure to meet applicable Availability standard	30% of the Monthly Recurring Charge for the affected circuits

b.: Mean Time To Restore, Error Free Seconds, Severely Errored Seconds and Latency.

Table A4b
Outage Credits—Mean Time to Restore, Error Free Seconds, Severely Errored Seconds, Latency

Months of Outage		Maximum Outage Credit Percentage
1^st Month of any Outage Condition		15% of Monthly Recurring Charge for affected circuits
2^nd Consecutive Month of the same Outage Condition		20% of Monthly Recurring Charges for affected circuits
3^rd Consecutive Month of the same Outage Condition		25% of Monthly Recurring Charges for affected circuits
4^th Consecutive Month of the same Outage Condition		30% of Monthly Recurring Charges for affected circuits
5^th Consecutive Month of the same Outage Condition		35% of Monthly Recurring Charges for affected circuits

Example 3: Assumption: Customer purchases any PLQoS. If the first (1^st) month, the average percentage of Error Free Seconds per day for all Xxxxxxxx PLQoS Services ordered is less than 99.99% and the average number of Severely Errored Seconds per day for all Xxxxxxxx XX QoS services ordered is greater than 8, Customer would receive 15% of the MRC for each individual circuit which failed to meet either the 99.99% Error Free Seconds or the 8 Severely Errored Seconds per day. If, in the second (2^nd) month, the average Error Free Seconds for all Xxxxxxxx PLQoS Services ordered is less than 99.99% but the number of Severely Errored Seconds per day

for all Xxxxxxxx PLQoS Services orders is less than 8, Customer would receive 20% of the MRC for each individual circuit which failed to meet the 99.99% Error Free Seconds. If, in the third (3^rd) month, the Average Error Free Seconds for all Xxxxxxxx PLQoS Services ordered is greater than 99.99% Customer would not receive a credit on any circuits and the next month that any of the technical specifications were not met the remedy structure would be reset to the 15% credit level. Example 4: If in month one Xxxxxxxx fails to meet the 99.997% Availability metric for Gold PLQoS on a $10,000.00 circuit and also in that same month fails to meet the 99.99% Error Free Seconds metric, Customer would receive a credit on the next month's invoice equal to the greater of 30% MRC for the Gold Availability service level or 15% MRC for failure to meet the Error Free Seconds variable. So in this example Customer would receive $3,000.00 in credit on the next month's invoice ($10,000.00 * 30% = $3,000.00). All examples assume that Customer has complied with the procedures for requesting an Outage Credit.

4.2: Excessive Outages. For Platinum and Gold PLQoS only, if a single circuit experiences either (a) three (3) or more outages of fifteen (15) minutes duration or longer during any thirty (30) day period, or (b) one or more outages of fifteen (15) minutes each in each of three (3) consecutive months or (c) one (1) outage of more than twenty-four (24) consecutive hours in a one (1) calendar month period, ("Excessive Outage"), Customer shall be entitled, in addition to the applicable Outage Credit, if any, to terminate such circuits as are affected by the Excessive Outage without liability for the Early Termination Charge set forth in Section 6.4 of the Agreement. However, Customer shall be liable for any termination liability associated with Third Party Local Access Service or any other Third Party Service associated with such disconnection.
4.3: Remedy. The Outage Credit and right to terminate for an Excessive Outage as set forth in this Section 4 shall be the sole and exclusive remedy of Customer in the event of any Outage and under no circumstances shall an Outage be deemed a default under the MSA. The Outage Credit amount provided to Customer will not be cumulative but will be the greater of the applicable Outage Credit for Availability or the Technical Specification variables addressed in Table A4b.
4.4: Limitations Customer shall not receive an Outage Credit if the Outage is (i) of a duration of less than two (2) consecutive hours; (ii) caused by Customer or others authorized by Customer to use the Services under the Agreement; (iii) due to the failure of power, facilities, equipment, systems or connections not provided by Xxxxxxxx; (iv) caused by the failure of Third Party Local Access Service to Xxxxxxxx' fiber optic network; (v) the result of scheduled maintenance where Customer has been notified of scheduled maintenance in advance; or (vi) due to a Force Majeure event as defined in the Agreement.
4.5: Credit Payment. Outage Credits shall be credited on Customer's next monthly invoice for the affected Service.

Section 5. Technical Specifications

5.1

Technical Specifications DS-3 service is provided in accordance with ANSI Standard T1.102 and T1.404. DS-3 Service operates at 44.736 Mbps. Optical SONET Services are provided in accordance with ANSI Standard T1.105. OC-3 service operates at 155.52 Mbps, with 3 separate STS-1 signaling paths, and an OC-3c operating at 155.52 Mbps contains 1 STS-3c signaling path. OC-12 Service operates at 622.080 Mbps with either 12 separate STS-1 signaling paths or 4 separate STS-3c paths. OC-12C Service operates at 622.080 Mbps with 1 STS-12C signaling path). The standards by which Xxxxxxxx' Private Line Service is measured apply on a one-way basis between Xxxxxxxx' POPs only and involves the five (5) variables set forth in the subsections below.

(a): Network Availability. Network Availability is a measurement of the average percent of total time that service is operative when measured in a month. DS-3 and Optical SONET Service is considered inoperative when there has been a loss of signal or when two consecutive 15

second loop-back tests confirm the observation of a bit error rate equal to or worse than 1 × 10^-6. A Service deemed inoperative under this description will not be included in measurements for Error Free Seconds or Severely Errored Seconds. Network Availability for Xxxxxxxx' PLQoS excludes switch time. Network Availability, excluding switch time, for Private Line QoS will be as follows: Platinum QoS has 100.00% availability; Gold QoS has 99.997% availability; Silver QoS has 99.5% availability and Bronze QoS has 99.00% availability and is a service objective only. Network Availability for Services of a Third Party Provider is established by the Third Party Provider. The local access availability standards for DS-3 and Optical SONET Services are established by the Local Access Service provider and are not considered in determining whether Xxxxxxxx Service has met the Technical Specifications in determining Outages and Outage Credits.

(b): Mean Time to Restore. Mean Time to Restore (MTTR) shall be the average time required to restore Service and resume availability when measured in a month. The time is measured from the moment the outage is reported until the first fiber is repaired. With respect to Xxxxxxxx Private Line Service, Xxxxxxxx will repair network equipment within an average of two (2) hours and the first fiber on a cable cut within an average of four (4) hours when averaged over a the rolling periods set forth above. Xxxxxxxx will undertake repair efforts on equipment or fiber when Xxxxxxxx first becomes aware of the problem, or when notified by Customer and Customer has released all or part of the Service for testing. The maintenance standards in this Section only apply for equipment or fiber on Xxxxxxxx' owned and operated network and from Xxxxxxxx' POP to Xxxxxxxx' POP.
(c): Error Free Seconds. Performance is noted in Error Free Seconds (Error Free Seconds ("EFS")) which is a measure of the percentage of the total seconds that do not contain bit errors over a consecutive twenty-four (24) hour period and averaged over a one month (720 hour) period. Long term performance shall be derived from Errored Seconds incidents in accordance with Telecordia Technologies Generic Criteria GR-499-CORE, Section 4.2 for DS-n services and GR-253-CORE. For Services on the Xxxxxxxx' network EFS shall be 99.99% per day. For Services not on Xxxxxxxx' network, the EFS standard for local access DS3 and Optical SONET Service is established by the third party services provider. Services from a third party provider are not considered in determining whether Xxxxxxxx Service has met the Technical Specifications in determining Outages and Outage Credits.
(d): SONET Severely Errored Seconds. A SONET Severely Errored Second ("SSES") is any one-second interval in which 2400 or more STS Path BIP errors were detected, AIS-P, LOP-P, or lower level, traffic related near end defect is detected in accordance with Telecordia Technologies Generic Criteria GR-253-CORE, Section 6.2.2.5.1. The number of Severely Errored Seconds shall not exceed eight (8) in a twenty-four hour period averaged over one month (720 hours). For Services not on Xxxxxxxx' network, the SSES standard for local access DS3 Service is established by the Third Party Services provider.
(e): Latency. Latency is defined as the one-way trip time required for a bit to travel between Xxxxxxxx' owned and operated POPs. Latency is measured as one-half of the roundtrip delay from the local customer demarcation point to the remote customer demarcation point. For Xxxxxxxx' PLQoS Services on Xxxxxxxx' network average Latency will be one millisecond (1ms) per one hundred (100) route miles.

Section 6. Product Intervals

Implementation Intervals. Xxxxxxxx' standard service implementation interval for DS3 Service is set forth below in Table A.6. Third Party Provider Service implementation intervals shall be determined on an individual case basis. Xxxxxxxx shall make reasonable efforts to provide Xxxxxxxx' Services within its

standard service implementation interval. Failure of Xxxxxxxx to deliver by such date shall not constitute a default under the MSA and Xxxxxxxx shall not be liable to pay to Customer any penalties or damages for Xxxxxxxx' failure to meet such standard service implementation intervals, except for the credits set forth in Section 3.4 of the Agreement.

Section 7. Planned Network Maintenance Activity

7.1: Timing. Xxxxxxxx shall avoid performing network maintenance between 0600 to 2200 Central Time (or local time with respect to facilities comprising international Service), Monday through Friday, inclusive, that will have a disruptive impact on the continuity or performance level of Customer's Service. However, the preceding sentence does not apply to restoration of continuity to a severed or partially severed fiber optic cable, restoration of dysfunctional power and ancillary support equipment, or correction of any potential jeopardy conditions. Xxxxxxxx will use commercially reasonable efforts to notify Customer prior to emergency maintenance.
7.2: Notice. Xxxxxxxx shall provide Customer with electronic mail, telephone, facsimile, or written notice of all non-emergency, planned network maintenance (i) not less than *** business days prior to performing maintenance that, in its reasonable opinion, has a substantial likelihood of affecting Customer's traffic for up to *** milliseconds, and (ii) not less than *** business days prior to performing maintenance that, in its reasonable opinion, has a substantial likelihood of affecting Customer traffic for more than *** milliseconds. If Xxxxxxxx' planned activity is canceled or delayed, Xxxxxxxx shall promptly notify Customer and shall comply with the provisions of this Section to reschedule any delayed activity.

Section 8. Warranty

Xxxxxxxx warrants that Xxxxxxxx' PLQoS shall be provided to Customer in accordance with the applicable Technical Specifications set forth above. Xxxxxxxx shall use commercially reasonable efforts under the circumstances to remedy any delays, interruptions, omissions, mistakes, accidents or errors in the Service and restore such Service to comply with the terms hereof. THE FOREGOING WARRANTY IS THE SOLE AND EXCLUSIVE WARRANTY AND IS PROVIDED IN LIEU OF ALL OTHER WARRANTIES WHETHER EXPRESS OR IMPLIED INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTY OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE OUTAGE CREDITS REMEDY AND RIGHT TO TERMINATE FOR EXCESSIVE OUTAGES PROVIDED TO CUSTOMER AS SET FORTH IN SECTION 4 OF THIS SERVICE SCHEDULE IS THE SOLE AND EXCLUSIVE REMEDY PROVIDED TO CUSTOMER AND IS IN LIEU OF ALL OTHER REMEDIES, REGARDLESS OF WHETHER THIS WARRANTY FAILS OF ITS ESSENTIAL PURPOSE.
