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)&nbsp;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;

SIZE=2><I>&nbsp;&nbsp;&nbsp;&nbsp;Service Term Adjustment.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;After any Existing Circuit has been in effect for a period of at least twelve
(12)&nbsp;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)&nbsp;a minimum Service Term of twelve months, b)&nbsp;the same or
greater total Service Term value, and c)&nbsp;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&nbsp;3 herein. For example: If Customer has (3)&nbsp;DS-3s which have been in effect for at least 12&nbsp;months with 24&nbsp;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&nbsp;months by placing a Service Order and by accepting Service
of a circuit or circuits pursuant to Section&nbsp;3.3 herein, that have: 1)&nbsp;a twelve month term and 2)&nbsp;a total MRC greater than or equal to those DS-3s and 3)&nbsp;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). </FONT></P>

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. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Requested Start Date.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;When a Service Order is placed, Customer will designate: (i)&nbsp;a requested start date ("Requested

obtaining Third Party Local Access Services; and (vi)&nbsp;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. </FONT></P>

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. </FONT></P>

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

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. </FONT></P>

<P><FONT SIZE=2><B>Non-Recurring and Enhanced Service Charges.  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;New Order Installation.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;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. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Change of Service Order Charge.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;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. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Order Cancellation Charge.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;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. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ASR Special Access.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;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. In
addition to WilTel' administrative charge, Customer shall be responsible for all charges imposed by Third Party Local Access providers in fulfilling the request. This charge applies to both data and
voice services. </FONT></P>

<P><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Order Expedite Charge.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;An Order Expedite Charge will apply when Customer requests that a Service be turned-up on
a date, which is earlier than WilTel' standard implementation interval. If Customer requests that a Service Order be expedited and the expedited order fails to be installed in the standard interval,
the expedite charge will still apply. This charge applies to both data and voice services. </FONT></P>

<DT style='margin-bottom:-11pt;'><FONT SIZE=2>1.1</FONT></DT><DD><FONT SIZE=2><I>Service Description.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;WilTel' Private Line Service ("Private Line Service") provides domestic DS-1,
DS-3 and Optical SONET (OC-N) circuits which are specifically dedicated to Customer's use between two (2)&nbsp;points specified by the parties in a Service Order and meeting
the technical requirements as defined below in Section&nbsp;5, Technical Specifications for Private Line Service. In addition, Private Line Service includes only those circuits where the entire
circuit shall be located solely upon the WilTel' owned and operated network and both end points of such circuit shall originate or terminate at a WilTel point of presence. </FONT></DD></DL>

<DL compact>
<DT style='margin-bottom:-11pt;'><FONT SIZE=2>2.1</FONT></DT><DD><FONT SIZE=2><I>Monthly Recurring Rates.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;Interexchange Rates. WilTel will provide Customer with a Rate Sheet for this Service.
Interexchange rates for Private Line Services wholly on WilTel' owned and operated network are as set forth in the 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)&nbsp;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 network will be determined on an individual case basis and set forth on Customer's Service Order.
<BR><BR></FONT></DD><DT style='margin-bottom:-11pt;'><FONT SIZE=2>2.3</FONT></DT><DD><FONT SIZE=2><I>Third Party Local Access Rates.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;If a Customer requests a Letter of Agency ("LOA") for a DS1 Private Line circuit, WilTel
will issue LOA/CFA (Carrier Facilities Assignment) from the ILEC Central Office, which serves WilTel's facilities. The Customer will then be responsible for a monthly recurring Local Service
Arrangement ("LSA") charge for the channel termination and any applicable mileage between the ILEC Central Office and WilTel's facilities. The LSA only applies to DS1 Private Line circuits and is set
forth in the Rate Sheet. Subject to Section&nbsp;4.3 of the Agreement, if WilTel issues CFA and an entrance facility charge for DS-3 through OC-48 Private Line circuits, or
for any Private Line circuits not entirely located on WilTel's owned and operated network applies, the entrance facility charge will be at the rates set forth in the Rate Sheet.

termination on a single DS-3 to another WilTel POP. For example, Customer orders five (5)&nbsp;DS1's from POP A to POP B. WilTel will mux the DS1's in POP A for transport on a single DS3
at the agreed upon rate and terminate a DS3 to Customer at POP B. WilTel will not demux the DS1's at the POP B location. </FONT></DD></DL>

switching and multiplexing technology, which can support applications requiring high bandwidth and high performance. ATM Service will allow Customers who have requirements for high speed,
inter-premise connectivity to interconnect their multiple locations via a User Network Interface (UNI) element from the Customer premise equipment (CPE) to the WilTel' point of presence (POP). ATM
Service is a general-purpose, connection-oriented technology that provides integration of disparate networks onto a single communications infrastructure. ATM Service provides the capability to route
traffic between various end points via virtual circuits that are predefined on the WilTel' ATM network and in the equipment provided by the Customer (CPE). The Customer is responsible for segmenting
information into 53 byte cells for transport across the WilTel' ATM network. ATM Service provides networking capabilities suited for high-speed, low delay, bandwidth intensive applications
such as voice, video and data that require real-time or near real-time connectivity between multiple locations. In addition, ATM Service shall only be provided with respect to
those circuits where the entire circuit shall be located entirely upon the WilTel' owned and operated network and both end points of such circuit shall originate or terminate at a WilTel' point of
presence. </FONT></DD></DL>

<BR><BR></FONT></DD><DT style='margin-bottom:-11pt;'><FONT SIZE=2>2.3</FONT></DT><DD><FONT SIZE=2><I>Virtual Circuits.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;There are two types of virtual circuits, which can be selected, the Virtual Channel Connection (VCC) or
the Virtual Path Connection (VPC). 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<SUP>non real time</SUP> (VBR<SUP>nrt</SUP>) 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.

and involves two variables: Network Availability and Mean-time-to-restore. Mean-time-to-restore is discussed in
Section&nbsp;5.3 of this Schedule.

POP measured over a one (1)&nbsp;year period. Network Availability for Services of a Third Party Provider is established by the Third Party Provider. The Local Access Service availability standards

an objective of repairing network equipment within an average of two (2)&nbsp;hours and an objective to have the first fiber on a cable cut restored within an average of six (6)&nbsp;hours. WilTel
will undertake repair efforts on equipment or fiber when WilTel first becomes aware of the problem, or when notified by Customer and Customer has released all or part of the Service for testing. The

point-to-point transport service that connects a Customer's international cable network to WilTel' domestic U.S. network. Customer may order International Backhaul Service at
STM-1 capacity at the China U.S. Cable and Southern Cross Cable Network ("Southern Cross") and STM-1, STM-4 or STM-16 capacity at the Japan U.S. Cable
and TAT-14 ("TAT-14"), subject to availability. WilTel will pick up Customer's traffic, which enters the U.S. via a cable system at a cable landing station. The cable landing
stations where WilTel may pick up Customer's traffic for the individual cable systems are as set forth in Table G.1 below. The origination demarcation point for International Backhaul Service shall be
at the system interface of the landing station of the applicable cable system (the "Origination Demarcation Point"). Customer will designate on each Service Order at which cable landing station the
Service is to originate. Once WilTel's picks up the traffic at the cable landing station, it will then carry the traffic to one of WilTel' designated termination
points-of-presence ("Termination POP"), which will also be specified by Customer on the Service Order. The Termination POPs for each landing station are set forth in Table F.1
below. </FONT></DD></DL>

or unprotected, concatenated OC-48 and OC-192 wavelengths. To provide Metro Wave Service, Williams uses dense wavelength division multiplexing ("DWDM") technology to multiplex
OC-48 and OC-192 signals at unique wavelengths over a single optical fiber. Metro Wave Service will originate at the fiber cross connect in a Williams' metro access point
("MAP(s)") designated in the applicable Service Order as the origination point, and will terminate at the fiber cross connect in the MAP designated in applicable the Service Order as the termination
point. The MAPs constituting the end points of each Metro Wave Service circuit shall both be located within the same Metro Wave Market, as defined below, or shall be located within adjacent Metro Wave
Markets (for example, a Metro Wave Service circuit may extend between MAPs located in Anaheim and Los Angeles). Protected Metro Wave Service is an optional Service configuration in which Williams'
owned or operated equipment located at the originating MAP (i.e., the MAP where Customer transfers its traffic to Williams) duplicates Customer's signal and transmits each signal over separate optical
fibers to the terminal MAP. Williams owned or operated equipment located in the terminal MAP chooses the signal of superior quality, or the surviving signal if only one signal arrives, and delivers it
to Customer. Unprotected Metro Wave Service is a Service configuration where only one signal is transmitted between MAPs. The provisions of Article&nbsp;4 of the MSA (Local Access Services) shall
not apply to Metro Wave Service and Metro Wave Service shall not be considered a Third Party Service.

3: Assumption: Customer purchases any PLQoS. If the first (1<SUP>st</SUP>) month, the average percentage of Error Free Seconds per day for all Williams PLQoS Services ordered is less than
99.99% and the average number of Severely Errored Seconds per day for all Williams PL 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<SUP>nd</SUP>) month, the average Error Free Seconds for all Williams PLQoS

for all Williams 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<SUP>rd</SUP>) month, the Average Error Free Seconds for all Williams 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 Williams 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%&nbsp;= $3,000.00). All examples assume that Customer has complied with the procedures for requesting an Outage Credit. </FONT></P>
