(“IRU Grantee”), and amends that certain IRU Agreement between the parties dated September, 28, 2001 (the “Agreement”). 
 RECITALS: 
 WHEREAS, Pursuant to Article I of the Agreement, IRU Grantee desires to purchase
additional IRU Fibers from McLeodUSA along the route and as more particularly described in Exhibit A-3 attached hereto (the “***Metro Fibers”) and McLeodUSA desires to sell such IRU Fibers to IRU Grantee; and

 WHEREAS, McLeodUSA and IRU Grantee desire to otherwise amend the Agreement, it being understood that certain amendments herein
shall apply on a prospective basis, all as further set forth herein 
 NOW THEREFORE, in consideration of the mutual promises
contained herein and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree hereto as follows: 
 1.     Capitalized Terms. All capitalized terms used herein shall have the same meaning s ascribed to them in the Agreement unless otherwise specifically set forth herein. 
 2.     Term. The following sentence is hereby added to Section 2.1 of the Agreement: 
 “Upon the mutual written agreement of the parties prior to the expiration hereof, the Term hereunder may be extended for two
(2) additional extension terms of five (5) years each, upon the same terms and conditions contained herein; provided that IRU Grantee shall not be required to pay any additional non-recurring costs for such extensions.” 
 3.     Rights at End of Term. Section 2.2 is amended to read as follows: 
 “At the end of the term, and upon any relocation, condemnation, or other substitution of any nature of the IRU Fibers pursuant to
Articles VI, XII, XIV, or Article XXV, or otherwise, the IRU granted hereunder shall immediately terminate. McLeodUSA shall thereafter be deemed to have immediately transferred title to the IRU Fibers, along with an undivided interest in the conduit
containing the IRU Fibers (but not the other Associated Property), to IRU Grantee. At such time as McLeod USA transfers title to the IRU Fibers, this Agreement shall terminate only as to the IRU granted hereunder, but shall otherwise remain in
effect perpetually as to the Associated Property.” 
 4.     Obsolescence. Section 6.5 of the
Agreement is hereby deleted and replaced init entirety with the following: 
 “If the grantees of at least fifty percent
(50%) of the fibers on the McLeodUSA Network containing the IRU Fibers deem the fiber to be functionally obsolete, then McLeodUSA may offer to IRU Grantee, on not less than one hundred twenty (120) days’ written notice, to substitute
for the IRU Fibers on the McLeodUSA Network an equal number of alternative fibers along the 

 
same or an alternative route; provided that in any such event, such substitution (a) shall be without unreasonable interruption of service and use by
the applicable party; (b) shall be constructed and tested in accordance with the applicable specifications; and (c) shall not adversely affect the use, operation or performance of the party’s network or business. IRU Grantee shall
have the right to either accept the proposed substitute fibers or retain the IRU Fibers as initially configured pursuant to this Agreement, provided, however, that if IRU Grantee elects to retain the IRU Fibers as initially configured, IRU Grantee
shall pays its remain Proportionate Share (depending on the number of remaining users) of costs for maintaining such IRU Fibers and of costs associated with the Rights and of any other costs relating to such IRU Fibers for the remainder of the Term.
McLeodUSA shall provide IRU Grantee with such information as IRU Grantee may reasonably require in order to determine the amount of such costs prior to electing to accept or reject the proposed substitute fibers. In the event of a fiber substitution
hereunder, all costs of such substitution, including, without limitation, all disconnect and reconnect costs, fees and expenses, or other reasonable costs associated with the substitute fibers and the provision of the substitute fibers, costs of
fiber, Rights, conduit (if applicable), and any other cost otherwise required to be borne by IRU Grantee under this Agreement shall be shared by the parties in the following order and amounts: (i) if the affected portion of the McLeodUSA
Network includes any sheath/conduit other than the sheath/conduit housing the IRU Fibers, the total costs shall be allocated equally among all of the affected sheaths/conduits; and (ii) the costs related to the sheath/conduit carrying the IRU
Fibers plus the costs specifically related to the fibers within such sheath/conduit shall be allocated between IRU Grantee and McLeodUSA and other others based on IRU Grantee’s Proportionate Share. The foregoing notwithstanding, as a condition
to paying its share of such fiber substitution costs, IRU Grantee shall be entitled to negotiate an extension to the Term of this Agreement for the reasonably anticipated useful life of the substitute fibers. Except as may be agreed by the parties,
in the event of a substitution of fibers, the substitute fibers shall be subject to the same acceptance procedures as the original fibers being granted hereunder and the Term of the IRU shall not exceed twenty (20) years following the Effective
Date for the substitute fibers.” 
 5.     Non-Performance of Maintenance Obligations.
Section 6.6 is hereby added as follows: 
 “In the event McLeodUSA at any time during the Term discontinues or fails
to perform maintenance and/or repair of the Cable, IRU Grantee may give written notice to McLeodUSA identifying such failure. If McLeodUSA does not cure such failure within thirty (30) days of IRU Grantee’s notice (or in the case of any
emergency, if McLeodUSA does not respond in accordance with Section 6.2 (a) of this Agreement), subject to Article XI, IRU Grantee, or its designated contractor, shall have the right, but not the obligation, to provide for the maintenance
and repair of the IRU Fibers in the Cable at IRU Grantee’s sole cost and expense until such failure is cured by McLeodUSA in any given case. In such case, in the event of a non-emergency situation, IRU Grantee shall send McLeodUSA a notice
naming the contractor to be used with respect to any maintenance or repair hereunder and providing such information as is necessary in order to give McLeodUSA sufficient notice to have a representative present during any such maintenance or repair.
Such notice shall not be necessary in the case of an emergency, provided however that IRU Grantee shall give notice to McLeodUSA of any such action taken as soon as practicable thereafter. Any McLeodUSA representative so present shall have the
authority to modify or temporarily halt the work to the limited extent reasonably necessary to protect the integrity of the McLeodUSA Network. Any such contractor to be used by IRU Grantee shall also be pre-approved in writing by McLeodUSA, which
approval shall not be unreasonably withheld or delayed, and which approval shall be deemed given in the event McLeodUSA fails to respond within ten (10) days after receipt of such notice. McLeodUSA shall, upon the request of IRU 

 
Grantee, obtain for IRU Grantee, or its designee, adequate access to the easements or Rights on or within which the IRU Fibers are located, for the purpose
of permitting IRU Grantee, or its designee, to undertake maintenance and repair of the IRU Fibers as contemplated herein. IRU Grantee shall be entitled to a credit from McLeodUSA of a prorated portion of its prepaid annual maintenance fee against
the next year’s fee and shall have no obligation to pay any maintenance fee pursuant to Section 5.4 for such period of time as McLeodUSA fails to perform such maintenance. Notwithstanding anything to the contrary contained in the
foregoing, in the event McLeodUSA fails to meet its obligation to maintain and/or repair the IRU Fibers pursuant to this Agreement and this Section 6.6 three (3) times in any twelve (12) month period, IRU Grantee shall have the right,
but not the obligation, to elect to perform its own maintenance and repairs on the IRU Fibers for the remainder of the Term hereof and shall be relieved of any maintenance fees payable hereunder. Subject to any other limitation on damages or
liability contained in this Agreement, nothing in this Section shall be construed to otherwise limit the rights of IRU Grantee to seek any other remedy available for any such failure by McLeodUSA to meet is maintenance and repair obligations under
this Agreement.” 
 6.    Tax and Accounting Treatment of IRU. Section 9.5 is hereby added as
follows: 
 “Notwithstanding the fact that McLeodUSA will continue to hold legal title to the IRU Fibers during the Term,
it is agreed that the grant of the IRU is a passage of equitable title and shall be treated for all accounting and all applicable tax purposes as the sale and purchase of the IRU Fibers, and that IRU Grantee shall be treated as the beneficial owner
thereof, having assumed all burdens therefore from and after Acceptance. The parties shall maintain their books and records and make all relevant tax filings consistently with the foregoing. In addition, given the foregoing intent of the parties, in
the event that any modification to any provision of this Agreement is necessary or desirable at any time under the terms hereof in order to satisfy any current or future accounting rule or other guideline relating to such accounting and tax
treatment, IRU Grantee hereby agrees that in consideration of the IRU granted hereunder, it shall make whatever reasonable modifications may be necessary hereunder in order to satisfy such current or future rule or guideline as if the modification
where a part of this Agreement as of the date hereof, provided such modification or alteration shall not materially and/or adversely affect IRU Grantees rights or obligations hereunder. 
 7.    Relocation. The following clause contained in Section 12.1 is hereby deleted in its entirety; provided
however, that the deletion set forth herein shall apply only to purchases of IRU Fiber from and after the date hereof and shall not apply to IRU Fibers purchased previously by IRU Grantee under this Agreement. 
 “..and the gross cost (excluding reimbursements) of the relocation exceeds $5,000 per occurrence, ...” 
 8.    Abandonment. Article XVI is hereby deleted in its entirety. 
 9.    Liens and Encumbrances. Article XXIII is hereby deleted in its entirety and replaced with the following:

 “IRU Grantee agrees and acknowledges that it has no right to use any of the fibers, other than the IRU Fibers,
included in the McLeodUSA Cable or otherwise incorporated in the McLeodUSA Network and that IRU Grantee shall keep any and all of the McLeodUSA Network, other than the IRU Fibers, free from an liens, rights or claims of any third parties
whatsoever.” 

 10.    Expiration or Termination. Section 25.4 is hereby
renumbered Section 25.3, and the following is hereby added as Section 25.4: 
 “Within a reasonable period
prior to the expiration of the Term hereof, McLeodUSA shall use commercially reasonable efforts, and shall cooperate with IRU Grantee, to preserve any Rights necessary for IRU Grantee’s continued use of the IRU Fibers upon transfer of title
pursuant to Article II herein. Upon the expiration or termination of any Right before the end of the Term that is necessary in order to grant, continue or maintain the IRU granted hereunder, the Term of the IRU hereunder shall automatically expire
upon such expiration or termination of the Right. Notwithstanding the foregoing, in the event McLeodUSA elects to relocate the McLeodUSA Cable and IRU Grantee elects to relocate with McLeodUSA, then notwithstanding the expiration of the Term, the
IRU Grantee shall pay McLeodUSA for IRU Grantee’s Proportionate Share of the reasonable costs and expenses incurred as a result of such relocation pursuant to Article XII herein.” 
 11.    No Further Amendments. Except as specifically set forth herein, the Agreement shall remain unmodified and in
full force and effect. 
 IN WITNESS WHEREOF, the parties have executed this First Amendment to IRU Agreement as of the date first
written above.

 Other Special Provisions: 
 1. Effective on the date of this Exhibit A-8, the Dark Fiber Capacity Services Agreement
executed between the parties on April 11, 2003 shall become null and void, and shall be superceded by the Agreement and this Exhibit A-8. The parties acknowledge and agree Fibers described in the Capacity Agreement and in this Exhibit A-8 have
been accepted by IRU Grantee. 
 2. McLeodUSA hereby grants, bargains, sells and conveys to IRU Grantee the Fibers specifically described in this Exhibit A-8.
Except for the portions of the such Fibers that are subject to transfer restrictions set forth below (the “Restricted Fibers”), title to the Fibers, along with a Proportionate Share of an undivided tenant in common interest in and to
tangible and intangible property necessary to use the Fibers, including but not limited to cable sheathing, troughing, pedestals, slack containers, and related equipment (the “Associated Property”) (but excluding any electronic or optronic
equipment which shall be provided by IRU Grantee at its sole cost) shall pass immediately to IRU Grantee. With respect to the Restricted Fibers and appurtenant Associated Property, IRU Grantee shall be deemed to have an Indefeasible Right of Use for
the Term pursuant to the terms of the Agreement. IRU Grantee may at any time begin the process of obtaining permits, consents, franchises, or other authorizations from all relevant governmental entities or private parties as may be necessary for, or
incidental to, the transfer of title to the Restricted Fibers, at its sole cost and expense, and McLeodUSA shall reasonably cooperate with IRU Grantee in such efforts. When IRU Grantee has obtained all Rights necessary for the transfer of title to
the Restricted Fibers (or for one or more Segments thereof), title to such Restricted Fibers shall transfer to IRU Grantee and the IRU in the Restricted Fibers shall terminate. At IRU Grantee’s request, McLeodUSA shall give a Bill of Sale to
all or part of such Fibers. In addition, at the end of the Term, and upon any relocation, condemnation, or other substitution of any nature of the IRU Grantee Fibers pursuant to Articles XII, XIV, or Article XXIV, or otherwise, the IRU in the

 Restricted Fibers: 
 a. That portion of the
Fibers subject to a Licensing Agreement dated July ***, 2003, executed by and between McLeodUSA Telecommunications Services, Inc. and ***. 
 b. That portion of the Fibers subject to an Agreement dated April ***, 1998, executed by and between McLeodUSA Telecommunications Services, Inc. and ***. 
 3. The parties acknowledge (i) that Route 2 is not owned by McLeodUSA and is subject to that certain *** Agreement between McLeodUSA and *** dated July ***, 1998 (the “*** Agreement”); (ii) that the initial term of the
*** Agreement automatically extends for three additional five (5) year 

 
periods unless one of the parties thereto gives the other two (2) years written notice prior to the end of the initial term (or an extension term) of
its intent to terminate the *** Agreement. Accordingly, the initial term (“Initial Term”) of Route 2 hereunder shall end on ***, 2015. Notwithstanding, if *** exercises its right to terminate the *** Agreement at any time, Customer and
McLeodUSA shall be relieved of all obligations with respect to Route 2 at the end of the then applicable Term, and the Annual Maintenance Fee shall be adjusted accordingly. The parties further acknowledge and agree that, notwithstanding any
provision in the IRU Agreement or this Exhibit A-8 to the contrary, no Fiber or Associated Property that is owned by *** shall be conveyed to IRU Grantee. 
 4. A portion of the Segment is subject to a certain Agreement dated April ***, 1998, executed by and between McLeodUSA Telecommunications Services, Inc. and ***, pursuant to which McLeodUSA leases ducts and other facilities from ***.
Therefore, the parties acknowledge and agree that, notwithstanding any provision in the IRU Agreement or this Exhibit A-8 to the contrary, no duct or other Associated Property that is owned by ***, or its successors, shall be conveyed to IRU
Grantee. 
 5. In the event that McLeodUSA is forced in connection with the above-referenced agreements with *** or *** to decommission any collocation site
they will not be responsible for any costs associated with removal or relocation of the customer’s facilities or fiber.

 EXHIBIT B 
 SPLICING, TESTING AND ACCEPTANCE STANDARDS 
  

	1.	All splices will be performed with an industry, accepted fusion splicing machine. 

  

	2.	Splices will be qualified during the initial construction by the core alignment system on the fusion splicer. 

  

	3.	After end-to-end (site-to-site) connectivity on the fibers, bi-directional span testing will be completed. These measurements will be made after all cable installation activities
are complete for each span. Connectors will be cleaned as necessary to ensure accurate measurements are taken. 

  

	 	•	 	Installed loss measurements at 1550 nm will be recorded using an industry accepted laser source and power meter. Continuity testing (checking for “frogging”) will be done
on all fibers concurrently. 

  

	 	•	 	OTDR traces will be taken at 1550 nm and splice loss measurements will be analyzed. GN Nettest Laser Precision format will be used on all traces, unless another OTDR format is
agreed to by both parties. 

  

	 	•	 	All testing, power levels and OTDR traces, will be conducted at 1550 nm only. 

  

	 	•	 	OTDR traces shall be saved in a standard file naming convention. 

  

	 	•	 	One set of diskettes with OTDR traces will be provided. Power level results will be submitted on paper documentation. 

  

	4.	The splicing standards are as follows: 

  

	 	•	 	The objective loss value of the connector and its associated splice will be 0.50 dB or less. 

  

	 	•	 	The objective for each fiber within a span shall be an average bi-directional loss of 0.2 dB or less for each splice. For example, if a given span has 10 splices, each fiber shall
have a total bi-directional loss (due to the 10 splices) of 2.0 dB or less. Individual bi-directional loss values for each splice will be reviewed for high losses. 

  

	 	•	 	The aforementioned standards are objectives, not the basis for acceptance. The acceptance standard for each fiber per span shall be calculated as follows: 

Span Loss = a(span distance in kilometers) + b(0.2 dB/splice) + c(0.50 db/connector) 
 Where: 
 a = maximum
fiber loss in dB per kilometer for the specific fiber type/manufacturer at 1550 nm 
 b = number of splice locations for
the span 
 c = number of connectors for the span 
  

	5.	All connector splices will be protected with heat shrinks. Backbone splices may be stored in trays with bare fiber manifolds and RTV silicone protection. Buffer tubes/ribbons will
not be split across more than one splice tray. An industry accepted splice enclosure will be used on all splices.

 EXHIBIT G 
 ROUTINE MAINTENANCE STANDARDS 
 Maintenance of the fiber plant should be completed on a regular recurring
basis and documented. Properly installed fiber plant normally needs minimal routine maintenance. Most hazards to fiber plant are external in nature, such as dig ups, pole hits, gunshots, animals, etc. Most destructive events are detected immediately
and corrected with plant restoration. A well-implemented maintenance plan will permit correction of marginal plant conditions that might otherwise become restoration events. The McLeodUSA Network Management Center should be notified in advance of
any scheduled OSP maintenance activity reported or planned at McLeodUSA 1-800-332-2385 (fax 1-319-298-7375). 
 1.1 CABLE ROUTE SURVEILLANCE

 Outside Plant facilities (OSP) are periodically inspected by field personnel. During this periodic inspection the Cable route is driven/walked to inspect
for discrepancies that may affect cable integrity. Any discrepancies found are documented and forwarded into the Outside Plant Maintenance desk for correction and repair as necessary. The following are some of the OSP items that will be inspected:

  

	•	Cable route integrity (e.g.: erosion) 

  

	•	Condition of poles, pedestals, risers, lashing wire, route markers and signs 

  

	•	Clearance of aerial facilities 

  

	•	Construction activity in the area near the cable 

 1.2 PLANT LOCATION
REQUESTS 
 All facilities associated with this Agreement are located in states with statewide “one call” agencies for excavators to request and
notify utilities of digging in the vicinity of the McLeodUSA facilities. McLeodUSA will subscribe to these services and follow the guidelines and laws applicable to that state including the marking of their facilities within 48 hours of receipt of
request. McLeodUSA will also take action to insure excavator is aware and protect the facility during the excavation as required. 
 1.3 PLANT RELOCATION
REQUESTS 
 Plant relocation requests will be submitted to the manager of field operations to be reviewed for applicable resolution. Requests should be
responded to within 10 business days and scheduled as required taking into consideration the scope of work and the urgency of the activity.Fiber Optic Exchange Agreement and Grant of IRU

Fibers. The IRU Grantee shall have the right, subject to the protocols of the Rights-of-Way providers, to have a representative present any time maintenance or repairs are performed which may affect the IRU Grantee’s IRU Fibers. 
 ARTICLE X 
 SPLICING 
 10.1 IRU Fibers may be physically spliced into the Owner’s Cable. Splicing requires penetration of the Cable sheath, exposing the Fibers within the sheath. In order
to maintain the integrity of the Owner’s Cable after Acceptance, the Owner, or a contractor operating under the Owner’s direction, must perform all splicing performed on the Owner’s Cable. 
 10.2 For future expansion at existing splice points, the Owner will perform the necessary splicing upon written or email request by the IRU Grantee. Normal requests for
splicing shall be submitted at least thirty (30) business days prior to the requested splicing date, and expedited requests shall be submitted at least 72 hours prior to the requested splicing date. The Owner shall obtain any and all permits
necessary for such splicing. The IRU Grantee agrees that it will not perform any splicing or interfere in any manner with the Owner’s Cable. After Acceptance, the cost of splicing Fibers into the Owner’s Cable will be borne by the IRU
Grantee. The Optical Splice Points for each route shall be mutually agreed upon in writing by the parties. The Owner shall provide the IRU Grantee with a splicing and splice testing schedule(s) so the IRU Grantee’s representative may be
present, subject to protocols of Rights-of-Way agreements. Splicing documentation (ATP and test results) will be provided by US Xchange within ninety (90) days after splicing is completed. 
 10.3 The IRU Grantee shall provide thirty (30) days written notification to the Owner if a new splice point is needed after initial Acceptance of a Segment.

 10.4 All splicing will be performed by the fusion splicing method or by any other method that is mutually agreeable. 

 ARTICLE XI 
 WARRANTIES 
 11.1 Each Owner warrants at the time of Acceptance its constructed Cable(s) to be of good workmanship
and materials, except any materials which are separately warranted by the manufacturer, and further warrants the IRU Grantee’s IRU Fibers to perform and operate in accordance with the manufacturer’s specifications and industry standards.

 11.2 Each Owner represents and warrants that all equipment and materials to be used in the construction of the IRU Grantee’s Fibers covered by this
Agreement will be new, of good quality, properly constructed and/or installed, free of defects, and in conformity with the requirements of this Agreement. Such warranty shall be effective, with respect to each specific Segment, for the same period
of warranty provided to the Owner by its contractors (normally a one (1) year period from date of acceptance by the Owner). All work not conforming to the standards may be considered defective by the IRU Grantee and the Owner shall immediately
replace any damaged or defective work at its own expense. The Owner shall use reasonable efforts to promptly repair or replace all such defective work; provided that the Owner shall repair or replace such defective work within thirty (30) days
following its confirmation of the defect, unless reasonable circumstances dictate a shorter or longer period, in which event the parties shall in good faith mutually agree upon such period. All replaced defective equipment or items shall become the
sole property of the Owner. 
 11.3 Each Party’s sole and exclusive remedy and their sole and exclusive maximum liability under the warranties contained
in this Article shall be, at the sole option of the Owner, to repair (with new or functionally operative parts) or replace any defective portion of its Cable of which the Owner receives notice during the warranty period, provided that the Owner is
promptly notified in writing upon discovery by the IRU Grantee that any portion of the IRU Fibers has failed to conform with the terms of this Agreement, such writing to include an explanation of alleged defects. 
 11.4 In addition to the foregoing warranties, each Owner hereby assigns to the IRU Grantee, and the IRU shall have the benefit of, any and all contractors’ and
suppliers’ warranties with respect to the material in the Cable. 
 11.5 Both parties’ warranties do not extend to defects caused by acts of God,
accident, fire or other hazard, nor resulting from the IRU Grantee’s, its designees or third parties misuse, neglect, alterations, storage, attempts to repair, or use of other supplies not meeting specifications. 
 THE FOREGOING WARRANTIES AND REMEDIES CONSTITUTE THE ONLY WARRANTIES WITH RESPECT TO THE NORLIGHT CABLE AND US XCHANGE CABLE AND ARE EXCLUSIVE REMEDIES IN THE EVENT OF
BREACH OF SUCH WARRANTIES. SUCH WARRANTIES ARE IN LIEU OF ALL OTHER WARRANTIES, WRITTEN OR ORAL, STATUTORY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER PARTY SHALL IN
ANY EVENT BE LIABLE FOR ANY INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES OF ANY NATURE WHATSOEVER FOR ANY REASON. 

 ARTICLE XII 
 TAXES 
 12.1 As used in this Article XII, “Tax” or “Taxes” shall mean any and all taxes,
assessments, charges, levies, (hereinafter collectively referred to as “Taxes”) imposed by any authority having the power to tax, including any city, county, state, or federal government or quasi-governmental agency or taxing authority.

 12.2. Upon the IRU Grantee’s Acceptance of its IRU Fibers, it shall be responsible for any and all sales, use, income, gross receipts of other Tax
assessed on the basis of revenues received by the IRU Grantee pursuant to its use of its IRU Fibers. Upon the IRU Grantee’s Acceptance of its IRU Fibers, it shall be solely responsible for any real or personal property Taxes relating in any way
to its IRU Fibers, and the IRU Grantee shall reimburse the Owner for the IRU Grantee’s Proportionate Share if the Owner is assessed and pays any such Tax. The parties shall cooperate to minimize adverse tax consequences and may mutually amend
this Agreement to improve their respective company’s tax positions. 
 ARTICLE XIII 
 LIABILITY 
 13.1 Neither US Xchange nor Norlight shall
be liable to the other for any indirect, special, punitive or consequential damages (including, but not limited to, any claim from any customer for loss of services) arising under this Agreement or from any breach or partial breach of the provisions
of this Agreement or arising out of any act or omission of either party hereto, its directors, officers, employees, servants, contractors and/or agents. Both US Xchange and Norlight shall include in any agreement with any third party relating to the
use of the US Xchange Cable or Norlight’s Cable a waiver by such third party of any claim for indirect, special, punitive or consequential damages (including, but not limited to, any claim from any client or customer for loss of services)
arising out of or as a result of any act or omission by either party hereto, its directors, officers, employees, servants, contractors and/or agents. 
 13.2
Subject to the limitation on indirect, special, punitive, or consequential damages in Article 13.1, each party assumes, releases and agrees to indemnify, defend, protect and save the other (including its directors, officers, agents, representatives
and employees) harmless from and against any claim, damage, loss, liability, injury, cost and expense (including reasonable attorney’s fees and expenses) in connection with any loss or damage to any property or facilities of the indemnified
party arising out of or resulting in any way from the acts or omissions to act, negligence or willful misconduct of the indemnifying party, its directors, officers, employees, servants, contractors and/or agents in connection with the exercise of
its rights and obligations under the terms of this Agreement. The parties hereto expressly recognize and agree that each parties’ obligation to indemnify, defend, protect and save the other harmless is not a material obligation to the
continuing performance of the parties’ other obligations, if any, under the terms 

 
of this Agreement. In the event a party shall fail for any reason to indemnify, defend, protect and save the other harmless, the indemnified party hereby
expressly recognizes that its sole remedy in such event shall be the right to bring suit against the indemnifying party for its damages as a result of the indemnifying party’s failure to so indemnify, defend, protect and save harmless.

 13.3 Nothing contained herein shall operate as a limitation on the right of either party hereto to bring an action for damages, including consequential
damages, against any third party based on any acts or omissions of such third party as such acts or omissions may affect the construction, operation or use of the US Xchange Cable, the Norlight Cable or any IRU Fibers; provided, however, that each
party hereto shall assign such rights or claims, execute such documents and do whatever else may be reasonably necessary to enable the injured party to pursue any such action against such third party. 
 ARTICLE XIV 
 FORCE MAJEURE 

The obligations of the parties hereto are subject to force majeure and neither party shall be in default under this Agreement if any failure or delay in performance
is caused by strike or other labor dispute; accidents; acts of God; fire; flood; earthquake; lightning; unusually severe weather; material or facility shortages or unavailability not resulting from such party’s failure to timely place orders
therefor; lack of transportation; legal inability to access property; acts of any governmental authority; government codes, ordinances, laws, rules and regulations or restrictions (collectively “Regulations”) (but not to the extent the
delay caused by such Regulations could be avoided by rerouting the Cable if such a reroute was commercially reasonable); condemnation or the exercise of rights of eminent domain; war or civil disorder; or any other cause beyond the reasonable
control of either party hereto. The excused party shall use reasonable efforts under the circumstances to avoid or remove such causes of non-performance and shall proceed to perform with reasonable dispatch whenever such causes are removed or
ceased. Notification shall be given by the excused party of the cause and of the estimated duration, when possible. 
 ARTICLE XV 

PERMITS AND REQUIRED RIGHTS-OF-WAY 
 15.1 The Owner
shall obtain on or before Acceptance with respect to each Segment to be delivered hereunder, any and all right-of-way agreements, easements, licenses, rights, or other agreement necessary for the use of poles, conduit, cable, wire, physical plant
facilities, and/or access to real property underlying the Owner’s Cable (“Rights-of-Way”). Further, as of Acceptance, the Owner shall obtain any and all rights, licenses, franchises, authorizations, agreements, permits, and approvals
(including without limitation, any necessary local, state, federal or tribal authorizations and environmental permits) and collectively referred to as “Permits,” that are necessary for the installation and operation of the Owner’s
Cable. The Owner shall obtain all Rights-of-Way and Permits in the name of the Owner. In addition, the Owner shall use its reasonable best efforts to obtain Rights-of-Way which will allow the IRU Grantee access to its IRU Fibers in the presence of
US Xchange’s employee or agent. Both parties shall cooperate to obtain such Rights-of-Way. 

 15.2 It is expressly understood that US Xchanges’s and Norlight’s obligations under this Agreement are
conditioned upon and shall in all respects be subject to the continuation or acquisition of such Rights-of-Way and Permits. The parties shall use their best efforts to obtain or to cause such Rights-of-Way and Permits to remain effective through the
Term of this Agreement, and any extension thereof. Copies of any and all agreements with respect to the Rights-of-Way and Permits shall be made available to the other party upon request. If confidentiality obligations under such agreements preclude
provision of the entire document, summaries of the substantive provisions thereof will be provided. In the event the Owner is unable to resolve any issue with respect to Rights-of-Way in a manner reasonably acceptable to the IRU Grantee, the IRU
Grantee may, after providing the Owner thirty (30) days prior written notice, attempt to resolve the issue directly with the granter of such Rights-of-Way. 
 ARTICLE XVI 
 RELOCATION OF CABLE 
 16.1 If the Owner is required to relocate or replace its Cable or any of the appurtenant facilities used or required in providing the IRU, and the gross cost (excluding reimbursements) of the Owner’s relocation
or replacement exceeds $5,000 per occurrence, then, so long as such work is not necessitated by a breach of the Owner’s obligations, the IRU Grantee shall reimburse the Owner for the IRU Grantee’s Proportionate Share of such costs,
including, without limitation, fiber acquisition, splicing, and testing. In the event that a third party reimburses the Owner for all or a portion of the cost to perform such work, then this reimbursement amount shall reduce on a dollar for dollar
basis the aggregate amount of costs deemed to have been spent by the Owner. The Owner shall deliver to the IRU Grantee updated as-built drawings and Documentation with respect to any relocated portion of the Cable not later than one-hundred eighty
(180) days following such relocation. 
 16.2 The Owner shall give the IRU Grantee sixty (60) days prior notice of any such relocation, if
possible, and shall have the obligation to proceed with such relocation, including, but not limited to, the right to determine the extent of, the timing of, and methods to use for such relocation; provided that any such relocated Cable and Fibers
shall be constructed and tested in accordance with the specifications and requirements set forth in this Agreement. Acceptance of the relocated IRU Fibers shall be in accordance with Article V of this Agreement. In addition, the Owner shall use
reasonable efforts to ensure relocation shall not result in an adverse change to the operations, performance, or connection points with the network of the IRU Grantee, or end points of the applicable Cable. 
 16.3 The IRU Grantee has the right to review and approve the relocation plans of the Owner fourteen (14) days prior to any relocation and has the right to have,
subject to the protocols of the Rights-of-Way Agreements, a representative present at the time the Owner relocates the Cable that contains the IRU Grantee’s IRU Fibers. 

 ARTICLE XVII

Index. 
 17.2 Failure of either party to enforce the minimum insurance requirements listed above shall not relieve the other party of the responsibility for
maintaining these coverages. The parties shall furnish to each other certificates of insurance reflecting policies carried and limits of coverage as required above, which shall state that thirty (30) days notice shall be given prior to
cancellation, non-renewal or any material change in any such insurance coverage. The insurance for both parties shall name the other as an additional insured. Norlight shall name US Xchange of Wisconsin, L.L.C., US Xchange of Indiana, L.L.C., US
Xchange of Illinois, L.L.C., and US Xchange of Michigan, L.L.C., as additional insureds. 
 17.3 Contractor(s) employed by the parties to work on the Fiber
Optic Cable shall provide and maintain at all times during the provision of services to the parties the same types of and amounts of insurance (with the exception of the amount of Comprehensive General Liability Insurance), which insurance shall be
issued by companies approved by the parties. 
 For Comprehensive General Liability Insurance, contractor(s) shall carry:

  

	 	(1)	Combined Single Limit: $2,000,000 each occurrence; and 

  

	 	(2)	Bodily Injury and Property Damage: $2,000,000 general aggregate, $1,000,000 products and completed operations aggregate.

party prior to commencement of the provision of services. US Xchange of Wisconsin, L.L.C., US Xchange of Indiana, L.L.C., US Xchange of Illinois, L.L.C., and US Xchange of Michigan, L.L.C. shall be named as additional insureds. The certificates of
insurance shall show that the insurance is prepaid and in full force and effect and that such insurance shall not be canceled, non-renewed or changed during the term of this Agreement or during any extension thereof, without at least thirty
(30) days written notice to the Owner and IRU Grantee. The maintenance of insurance by the contractor shall in no way limit or affect the extent of the contractor’s liability. 
 ARTICLE XVIII 
 CONDEMNATION 
 18.1 In the event any portion of the US Xchange Cable and/or the Norlight Cable, or the Rights-of-Way in or upon which it has been installed, becomes the subject of a
condemnation proceeding by any governmental agency or other party cloaked with the power of eminent domain for public purpose or use, then and in such event, it is agreed that the IRU Grantee’s interest (being its Proportionate Share) shall be
severed from the Owner’s interest in such proceeding. The IRU Grantee shall be entitled to independently pursue an award for its interest in such proceedings and the parties hereto agree to have any such condemnation awards specifically
allocated between the Owner’s interest and the IRU Grantee’s interest. In the event the IRU Grantee’s interest in such proceeding cannot be severed from the Owner’s interest, the IRU Grantee shall be entitled to receive its
Proportionate Share of the award for its interest in the IRU Fibers and occupancy of the Rights-of-Way. 
 18.2 Upon its receipt of a formal notice of
condemnation or taking, the Owner shall notify the IRU Grantee immediately of any condemnation proceeding filed against the Owner’s Cable, including the IRU Grantee’s IRU Fibers, or the Rights-of-Way in or upon which the IRU Grantee’s
IRU Fibers have been installed. The Owner shall also notify the IRU Grantee of any similar threatened condemnation proceeding and agrees not to sell the Cable or release Rights-of-Way to such acquiring agency, authority or other party in lieu of
condemnation without the prior written consent of the IRU Grantee, which consent shall not be unreasonably conditioned, delayed or denied. 
 18.3 It is
expressly recognized and understood by the IRU Grantee that relocation costs resulting from any such condemnation proceeding may not be reimbursed by the condemning authority and, if the IRU Grantee requests the Owner to relocate the IRU
Grantee’s IRU Fibers, the IRU Grantee shall pay its Proportionate Share of all costs associated with the relocation of the IRU Grantee’s IRU Fibers in excess of such costs which were reimbursed by the condemning authority. If the IRU
Grantee’s IRU Fibers are relocated by the Owner pursuant to this Article 18.3, the IRU Grantee shall pay to the Owner all condemnation awards given to the IRU Grantee, if any, that relate to the relocation of that portion of the IRU
Grantee’s IRU Fibers. 

 ARTICLE XIX 
 CONFIDENTIALITY 
 19.1 Norlight and US Xchange represent, certify, and warrant that they shall use their best
reasonable efforts to ensure that any and all information and documents obtained from the other party during the term of this Agreement, and identified as being confidential information will be held in strict confidence and will not be used by their
company, its employees, subcontractors, consultants or agents for any purpose other than its performance required by this Agreement. 
 19.2 All documents,
data, or information furnished by Norlight and US Xchange is the sole property of that party. Upon the expiration of this Agreement and any extensions thereof, those documents, data, or information shall be returned to the Owner if readily
available. 
 19.3 Neither Norlight nor US Xchange may make any news release, public announcement, denial or confirmation concerning all or any part of this
Agreement or use the other’s name in sales or advertising materials, or in any manner advertise or publish the fact that the companies have entered into this Agreement, or disclose any of the details of this Agreement to any third party,
including the press, without the prior written consent of the other party, except such disclosures required by law, or the rules and regulations of the relevant government agencies. 
 ARTICLE XX 
 ABANDONMENT 
 Should the IRU Grantee decide to abandon all or part of its IRU Fibers, it may do so by informing the Owner in writing, such abandonment being made at no cost to either
party. The IRU Grantee shall remove its equipment and electronics within thirty (30) days of such notification of abandonment by the IRU Grantee, failing which the Owner shall remove same at the IRU Grantee’s costs payable within thirty
(30) days of receipt of the invoice. At the time of abandonment, the IRU Grantee shall have no further rights with respect to its IRU. Such abandonment shall not reduce or otherwise affect the IRU Grantee’s obligations hereunder.

 ARTICLE XXI 
 DEFAULT

 21.1 Neither party shall be in default under this Agreement unless and until the other party shall have given the defaulting party written notice of
such default and the defaulting party shall have failed to cure the default within thirty (30) days after written receipt of such notice; provided, however, that where a default cannot be reasonably cured within the thirty (30) day period,
if the defaulting party shall promptly proceed to cure the default with due diligence, the time for curing the default shall be extended for a period of up to ninety (90) days from the date of receipt of the default notice. 
 21.2 Upon the failure by the defaulting company to timely cure any default after notice thereof from the non-defaulting party, the non-defaulting party may take any
action it determines, in its discretion, to be necessary to correct the default, and/or pursue any legal remedies it may have under applicable law or principles of equity relating to the breach. 

 21.3 The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each party shall be entitled to injunctive or similar preliminary relief to prevent or cure breaches of the
provisions of this Agreement by the other and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they may be entitled by law or equity. 
 21.4 An event of default shall also be deemed to have occurred if a party becomes insolvent, or institutes or has instituted against it bankruptcy proceedings which are
not dismissed within ninety (90) days of filing, or makes a general assignment for the benefit of creditors, or if a receiver is appointed for the benefit of its creditors, or if a receiver is appointed on account of its insolvency, and the
non-defaulting party may immediately terminate this Agreement.

construed in accordance with the laws of the state in which the Cable is located, without regard to its conflict of laws principles. 
 ARTICLE XXV 
 INDEPENDENT CONTRACTOR 
 The performance by Norlight and/or US Xchange of all duties and obligations under this Agreement shall be as independent contractors and not as agents of the other party, and no persons employed or utilized by a performing party shall be
considered the employees or agents of the other. Neither party shall have the authority to enter into any agreement purporting to bind the other without its specific written authorization. The parties agree that this Agreement does not create a

 ARTICLE XXVI 
 DISPUTE RESOLUTION 
 26.1 It is the intent of US Xchange and Norlight that any disputes which may arise between them,
or between the employees of each of them, be resolved as quickly as possible. Quick resolution may, in certain circumstances, involve immediate decisions made by the parties’ representatives. When such resolution is not possible, and depending
upon the nature of the dispute, the parties hereto agree to resolve such disputes in accordance with the provisions of this Article. The obligation herein to arbitrate shall not be binding upon any party with respect to request for preliminary
injunctions, temporary restraining orders, specific performance or other procedures in a court of competent jurisdiction to obtain interim relief when deemed necessary by such court to preserve the status quo or prevent irreparable injury pending
resolution by arbitration of the actual dispute. 
 26.2 Norlight and US Xchange shall each designate, by separate letter, representatives as points of
contact and decision making with respect to the obligations and rights of the parties, said letters to be furnished by each party to the other within thirty (30) days from the date of this Agreement. Any disputed issues arising during the term
of this Agreement shall in all instances be initially referred to the parties’ designated representatives. The parties’ designated representatives shall render a mutually agreeable resolution of the disputed issue, in writing, within
seventy-two (72) hours of such referral. Either party may modify the designated representative upon written notice to the other party. 
 26.3 Any
claims or disputes arising under the terms and provisions of this Agreement, or any claims or disputes which the parties’ representatives are unable to resolve within the seventy-two (72) hour time period shall continue to be resolved
between the parties’ representatives if mutually agreeable, or may be presented by the claimant in writing to the other party within thirty (30) days after the circumstances which gave rise to the claim or dispute took place or become
known to the claimant, or within thirty (30) days after the parties’ representatives fail to achieve resolution, whichever is later. The written notice shall contain a concise statement of the claim or issue in dispute, together with
relevant facts and data to support the claim. 
 26.4 Any controversies or disputes arising out of or relating to this Agreement shall be resolved by binding
arbitration in accordance with the then current Commercial Arbitration Rules of the American Arbitration Association. The parties shall endeavor to select a mutually acceptable arbitrator knowledgeable about issues relating to the subject matter of
this Agreement. In the event the parties are unable to agree to such a selection, each party will select an arbitrator and the arbitrators in turn shall select a third arbitrator. 
 The arbitrator(s) shall not have the authority, power or right to alter, change, amend, modify, add or subtract from any provision of this Agreement, except pursuant to Article 29.3, or to award punitive damages. The
arbitrator shall have the power to issue mandatory orders and restraining 

 
orders in connection with the arbitration. The award rendered by the arbitrator shall be final and binding on the parties and judgment may be entered thereon
in any court having jurisdiction. The agreement to arbitration shall be specifically enforceable under the prevailing arbitration law. 
 26.5 During the
continuance of any arbitration proceeding, each party shall continue to perform their respective obligations under this Agreement. 
 ARTICLE
XXVII 
 LIENS 
 27.1 In the event the IRU
Fibers become subject to any mechanics’, artisans’ or materialmen’s lien, or other encumbrance chargeable to or through the Owner which interfere with the IRU Fibers or jeopardize the IRU Grantee’s use of its IRU Fibers, the
Owner shall promptly cause such lien or encumbrance to be discharged and released of record (by payment, posting of bond, court deposit or other means) without cost to the IRU Grantee and shall indemnify the IRU Grantee against all costs and
expenses (including attorney’s fees) incurred in discharging and releasing such lien or encumbrance; provided, however, that if any such lien or encumbrance is not so discharged and released within thirty (30) days after written notice by
the IRU Grantee to the Owner, then the IRU Grantee may pay or secure the release or discharge thereof at the expense of the Owner. The Owner shall reimburse the IRU Grantee for such payments within thirty (30) days of invoice by the IRU
Grantee. 
 27.2 The Owner agrees and acknowledges that it has no right to use any of the IRU Grantee’s IRU Fibers included in the Owner’s Cable.
The Owner shall obtain from any entity in favor of which the Owner in its discretion may grant after the date of this Agreement a security interest or lien on all or part of the Owner’s Cable, a written nondisturbance and subordination
agreement in form and substance reasonably satisfactory to the IRU Grantee. The nondisturbance and subordination agreement will be written to the effect that such lienholder acknowledges the IRU Grantee’s and other present or future
participants’ interest and rights in the IRU Grantee’s IRU Fibers and the IRU granted by this Agreement, and agrees that the same shall not be diminished, disturbed, impaired or interfered with in any adverse respect by such lienholder.

 27.3 The IRU Grantee agrees and acknowledges that it has no right to use any of the Fibers, other than the IRU Grantee’s IRU Fibers, included in the
Owner’s Cable or otherwise incorporated in US Xchange’s system and that the IRU Grantee shall keep any and all of the Owner’s system, other than the IRU Grantee’s IRU granted in the IRU Fibers, free from any liens, rights or
claims of any third party attributable to the IRU Grantee. Notwithstanding the aforementioned, the IRU Grantee shall obtain from any entity in favor of which the IRU Grantee in its discretion may grant after the date of this Agreement a security
interest or lien on all or part of such IRU granted by this Agreement, a written nondisturbance agreement substantially to the effect that such lienholder acknowledges the Owner’s and other present or future participants’ interest and
rights in the Owner’s Cable and agrees that the same shall not be diminished, disturbed, impaired or interfered with in any adverse respect by such lienholder.

remainder of the Agreement shall remain in full force and effect. However, in the event such a section or clause is an essential element of the Agreement, the parties shall promptly negotiate a replacement that will achieve the intent of such
unenforceable section or clause to the extent permitted by law.

against whom enforcement of the modification is sought. 
 28.5 No failure to exercise and no delay in exercising, on the part of either party hereto, any
right, power or privilege hereunder shall operate as a waiver hereof, except as expressly provided herein. Any waiver by either party of a breach of any provision of this Agreement shall not be deemed to be a waiver of any other or subsequent breach
and shall not be construed to be a modification of the terms of this Agreement unless and until agreed to in writing by both parties. 
 28.6 In the event of
a conflict between the provisions of this Agreement and those of Exhibit A and Exhibit B, the provisions of Exhibit A and Exhibit B shall prevail and the Agreement will be corrected accordingly. If there is a conflict

 EXHIBIT F CONT’D 
 ROUTINE MAINTENANCE STANDARDS 
 Maintenance of the fiber plant should be completed on a regular recurring basis and
documented. Properly installed fiber plant normally needs minimal routine maintenance. Most hazards to fiber plant are external in nature, such as dig ups, pole hits, gun shots, etc. Most destructive events are detected immediately and corrected
with plant restoration. A well implemented maintenance plan will permit correction of marginal plant conditions that might otherwise become restoration events. The Cable Owner’s Network Management Center should be notified in advance of any
scheduled OSP maintenance activity reported or planned at (US Xchange) 1-888-404-9748 (fax 1-616-454-2774) (Norlight) 1-800-809-4340 (fax 1-414-792-4051). 
 1.1 CABLE ROUTE SURVEILLANCE 
 Outside Plant facilities (OSP) are periodically inspected by field personnel. During this periodic inspection the
Cable route is driven/walked to inspect for discrepancies that may affect cable integrity. Any discrepancies found are documented and forwarded into the Outside Plant Maintenance desk for correction and repair as necessary. The following are some of
the OSP items that will be inspected: 
  

	•	 	Cable route integrity (e.g.: erosion) 

  

	•	 	Condition of poles, pedestals, risers, lashing wire, route markers and signs 

  

	•	 	Clearance of aerial facilities 

  

	•	 	Construction activity in the area near the cable 

 1.2 PLANT LOCATION
REQUESTS 
 All facilities associated with this Agreement are located in states with statewide “one call” agencies for excavators to request and
notify utilities of digging in the vicinity of the Owner’s facilities. The Owner will subscribe to these services and follow the guidelines and laws applicable to that state including the marking of their facilities within 48 hours of receipt
of request. The Owner will also take action to insure excavator is aware and protect the facility during the excavation as required. 
 1.3 PLANT RELOCATION
REQUESTS 
 Plant relocation requests will be submitted to the manager of field operations to be reviewed for applicable resolution. Requests should be
responded to within 10 business days and scheduled as required taking into consideration the scope of work and the urgency of the activity.
