ARTICLE I

FIBER OPTIC EXCHANGE

1.1 Norlight desires to obtain an IRU for single-mode optical fiber in a Cable owned by McLeodUSA specifically described in Exhibit A to this Agreement, which is incorporated into this Agreement by reference. From time to time additional routes may be added by amending Exhibit A to this Agreement. For each IRU granted, a separate Exhibit A, executed by both parties, will be attached hereto, titled so as to identify the Cable route and resulting IRU. Upon Joint Acceptance of a Segment by both Norlight and McLeodUSA, McLeodUSA grants an IRU to Norlight for the IRU Fibers specified in the applicable Exhibit A. At the time of Joint Acceptance, the Constructing Party warrants that it provides good and clear title to the Norlight IRU Fibers, such IRU Fibers being free and clear of all liens. Upon Acceptance, McLeodUSA also grants a non-exclusive right to use tangible and intangible property Norlight needs to use its IRU Fibers, including, but not limited to, cable sheathing, troughing, pedestals, slack containers, and related equipment, but excluding any electronic or optronic equipment. Norlight shall be entitled to use its IRU Fibers for any lawful purposes subject to i) agreeing to be bound by all laws, regulations and any requirements of Rights agreements relating to access, ii) agreeing to appoint McLeodUSA as its agent for matters relating to access to the Rights and iii) agreeing to notify McLeodUSA of any transfer and obtaining from any transferee undertakings to be bound by the above as per the terms and conditions of the Rights agreements.

1.2 McLeodUSA desires to obtain an IRU for single-mode optical fiber in a Cable owned by Norlight specifically described in Exhibit A to this Agreement. From time to time additional routes may be added by amending Exhibit A to this Agreement. For each IRU granted, a separate Exhibit A, executed by both parties, will be attached hereto, titled so as to identify the Cable route and resulting IRU. Upon Joint Acceptance of a Segment by both McLeodUSA and Norlight, Norlight grants an IRU to McLeodUSA for the IRU Fibers specified in the applicable Exhibit A. At the time of Joint Acceptance, the Constructing Party warrants that it provides good and clear title to the McLeodUSA IRU Fibers, such IRU Fibers being free and clear of all liens. Upon Acceptance, Norlight also grants a non-exclusive right to use tangible and intangible property McLeodUSA needs to use its IRU Fibers, including, but not limited to, cable sheathing, troughing, pedestals, slack containers, and related equipment, but excluding any electronic or optronic equipment. McLeodUSA shall be entitled to use its IRU Fibers for any lawful purposes subject to i) agreeing to be bound by all laws, regulations and any requirements of Rights agreements relating to access, ii) agreeing to appoint Norlight as its agent for matters relating to access to the Rights and iii) agreeing to notify Norlight of any transfer and obtaining from any transferee undertakings to be bound by the above as per the terms and conditions of the Rights agreements.

1.3 Consideration for the rights granted in Article I shall be the grant of IRUs as specified in Exhibit A. For reciprocal IRUs, the parties intend that such exchanges of McLeodUSA IRU Fibers for Norlight IRU Fibers will be classified for income tax purposes as an exchange of property pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, for accounting purposes and for federal and all applicable state and local income tax purposes, McLeodUSA shall be treated as the owner of the McLeodUSA IRU Fibers and Norlight shall be treated as the owner of the

Norlight IRU Fibers. To the greatest extent possible, delivery of the respective IRUs shall occur simultaneously on a date mutually agreed to by both parties and indicated on the respective Exhibits A. Notwithstanding the preceding, delivery of the respective IRUs may occur upon agreement of the parties and due to construction related delays in cable pulling or splicing work, to occur on separate dates, but in no event more than one hundred eighty (180) days apart and the parties shall take such action, or refrain from action, as the case may be, to ensure such timing and delivery falls within the mandatory requirement of the Code.

ARTICLE II

EFFECTIVE DATE AND TERM

2.1 The IRU Grantee will be entitled to use the IRU Fibers upon the Joint Acceptance of a route Segment. The initial IRU term shall start upon Joint Acceptance (“Effective Date”) and shall terminate on the earlier of twenty (20) years from the Effective Date of the last Segment of the routes described in Exhibit A, but in any event no later than year 2022, or at the end of the economic useful life of the IRU Fibers as determined by the IRU Grantee. The IRU Grantee will have an option to renew the term for two (2) additional ten (10) year periods. An election by either party to extend the term for its IRU Fibers must be given in writing to the Owner at least one (1) year prior to the expiration of the then current term or extension.

LIABILITY

13.1 Neither Norlight nor McLeodUSA 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 McLeodUSA and Norlight shall include in any agreement with any third party relating to the use of the McLeodUSA Cable or the Norlight 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. Notwithstanding any other provisions of this Agreement, with respect to the performance or interruption of any services provided by the IRU Grantee through the IRU Fibers, the Owner will not be liable for any damages (including without limitation, damages for harm to business, lost revenues, lost savings, or lost profits) claimed by the IRU Grantee or its end user customers or those to whom the IRU Grantee has entered into leases with or to whom it has granted IRUs in accordance with Section 23.4.

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 McLeodUSA Cable, 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

15.1 The Constructing Party shall obtain on or before Joint Acceptance with respect to each Segment to be delivered hereunder, any and all right-of-way agreements, easements, licenses, rights, or other agreements necessary for the use of poles, conduit, cable, wire, physical plant facilities, and/or access to real property underlying the Owner’s

Cable (“Rights”).

Copies of any and all agreements with respect to the Rights 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 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.

15.3 Each Constructing Party represents and warrants that, as of the date hereof, there is no litigation pending or, to the best of its knowledge, threatened regarding any of the Rights obtained or to be obtained by such Constructing Party requisite to the construction of the Owner’s Cable.

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 Agreements, a representative present at the time the Owner relocates the Cable that contains the IRU Fibers.

The obligation herein to arbitrate shall not be binding upon any party with respect to requests 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 McLeodUSA and Norlight 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.

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.

The nondisturbance and subordination agreement will be written to the effect that such lienholder acknowledges IRU Grantee’s and other present or future participants’ interest and rights in the 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 IRU Grantee agrees and acknowledges that it has no right to use any of the fibers, other than the IRU Fibers, included in the Owner’s Cable or otherwise incorporated in the Owner’s system and that IRU Grantee shall keep any and all of the Owner’s system, other than the IRU granted in the IRU Fibers, free from any liens, rights or claims of any third party attributable to IRU Grantee.

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 (McLeodUSA) 1800-332-2385 (fax 1-319-298-7375) or (                            ) 1800-      -         (fax 1-800-      -        )

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 Owners’ 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. “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.
