B. Pursuant to that certain Separation and Distribution Agreement, dated as of March 26, 2015 (the “ Distribution Agreement ”), by and among Communications Sales and Leasing, Inc., a Maryland corporation (“ CS&L Parent ”), Tenant and Windstream Services, LLC (formerly known as Windstream Corporation) (“ Win Services ”), Landlord desires to lease the Leased Property to Tenant and Tenant desires to lease the Leased Property (as defined below) from Landlord upon the terms set forth in this Master Lease.

C. A list of the approximately thirty six (36) facilities (each a “ Facility ,” and collectively, the “ Facilities ”) covered by this Master Lease, categorized by geographic area, is attached hereto as Exhibit A , which includes (i) the real property and improvements thereon owned by Landlord in the geographic area of such Facility as identified on Exhibit A attached hereto, and (ii) the Distribution Systems (as defined below) located in the geographic area of the applicable Facility as identified on Exhibit A attached hereto.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE I

1.1 Leased Property . Upon and subject to the terms and conditions hereinafter set forth, Landlord exclusively leases to Tenant and Tenant leases from Landlord all of Landlord’s rights, title and interest in and to the following with respect to each of the Facilities (collectively, the “ Leased Property ”):

(a) the real property or properties described in a letter, dated as of the date hereof, delivered by Tenant and acknowledged by Landlord, and all other real property or properties owned by Landlord in the geographical areas of each of the Facilities that are (i) the locations for central offices, remote switching locations or other switching facilities and (ii) necessary for the use and operation of, or currently used in the operation of, the Distribution Systems associated with such Facilities (collectively, the “ Land ”);

(b) all buildings, structures, and other improvements of every kind now or hereafter located on the Land or connected thereto including, but not limited to, alleyways and

connecting tunnels, sidewalks, utility pipes, conduits and lines (on-site and off-site to the extent Landlord has obtained any interest in the same), parking areas and roadways appurtenant to such buildings and structures, including all HVAC systems and components, generators, fire suppression systems and other fixtures (collectively, the “ Leased Improvements ”);

(c) all easements, rights and appurtenances relating to the Land and the Leased Improvements, including any Easements, Permits and Pole Agreements;

(d) all fiber optic cable lines, copper cable lines, conduits, telephone poles, attachment hardware (including bolts and lashing), guy wires, anchors, pedestals, concrete pads, amplifiers and such other fixtures, and other items of property, including all components thereof (such as cross connect cabinets, windstream outside plant mini-cabinet mounting posts (WOMP), fiber distribution hubs, fiber access terminals and first entry fiber splice cases), that are now or hereafter located in, on or used in connection with and permanently affixed to or otherwise incorporated into the Facilities, together with all replacements, modifications, alterations and additions thereto, up through and at the meeting and demarcation points described on Exhibit B attached hereto (collectively, the “ Distribution Systems ”); and

(e) all system maps and records for the Distribution Systems.

Notwithstanding anything to the contrary contained herein, the Leased Property shall exclude Tenant’s Property (including the Electronics, switching and equipment) and the Excluded Assets. The Leased Property is leased subject to all covenants, conditions, restrictions, easements and other matters affecting the Leased Property as of the Commencement Date and such subsequent covenants, conditions, restrictions, easements and other matters as may be agreed to by Landlord or Tenant in accordance with the terms of this Master Lease, whether or not of record, including any matters which would be disclosed by an inspection or accurate survey of the Leased Property.

1.2 Single, Indivisible Lease . This Master Lease constitutes one indivisible lease of the Leased Property and not separate leases governed by similar terms. The Leased Property constitutes one economic unit, and the Rent and all other provisions have been negotiated and agreed to be based on a demise of all of the Leased Property to Tenant as a single, composite, inseparable transaction and would have been substantially different had separate leases or a divisible lease been intended. Except as expressly provided in this Master Lease for specific, isolated purposes (and then only to the extent expressly otherwise stated), all provisions of this Master Lease apply equally and uniformly to all of the Leased Property as one unit. An Event of Default with respect to any portion of the Leased Property is an Event of Default as to all of the Leased Property. The parties intend that the provisions of this Master Lease shall at all times be construed, interpreted and applied so as to carry out their mutual objective to create an indivisible lease of all of the Leased Property and, in particular but without limitation, that, for purposes of any assumption, rejection or assignment of this Master Lease under 11 U.S.C. Section 365, or any successor or replacement thereof or any analogous state law, this is one indivisible and non-severable lease and executory contract dealing with one legal and economic unit and that this Master Lease must be assumed, rejected or assigned as a whole with respect to all (and only as to all) of the Leased Property. The parties may amend this Master Lease from time to time to include one or more additional Facilities as part of the Leased Property and such future addition to the Leased Property shall not in any way change the indivisible and nonseverable nature of this Master Lease and all of the foregoing provisions shall continue to apply in full force.

1.3 Term . The “ Term ” of this Master Lease is the Initial Term plus all Renewal Terms, to the extent exercised. The initial term of this Master Lease (the “ Initial Term ”) shall commence on execution date (the “ Commencement Date ”) and end on the last day of the calendar month in which the fifteenth (15 ^th ) anniversary of the Commencement Date occurs, subject to renewal as set forth in Section 1.4 below. Notwithstanding anything to the contrary contained herein, Tenant shall have the right to extend the Initial Term for a period of five (5) years (the “ Initial Extension Right ”) with respect to all of the Facilities (and in no event for less than all of the Facilities) by delivering Notice (the “ Initial Extension Notice ”) to Landlord at any time prior to the fifth (5 ^th ) anniversary of the Commencement Date of such election. In the event Tenant seeks to have Landlord provide the Funding Commitment as set forth in Section 10.2(b) hereof, Tenant shall include a request (a “ Funding Request ”) for such Funding Commitment from Landlord in the Initial Extension Notice. Upon receipt of an Initial Extension Notice with a Funding Request, Landlord shall have a period of thirty (30) days to evaluate such request and respond to Tenant in writing (“ Landlord Response ”), whether Landlord elects, in its sole and absolute discretion, to provide all or a portion of the Funding Commitment in accordance with Section 10.2(b).

If Tenant does not timely send the Initial Extension Notice pursuant to the provisions of this Section 1.3 or if Landlord does not send a Landlord Response agreeing to provide the Full Funding Commitment in accordance with Section 10.2(b), Tenant shall be deemed to have irrevocably waived the Initial Extension Right.

1.4 Renewal Terms . (a) Subject to Section 1.3, the term of this Master Lease may be extended for four (4) separate “Renewal Terms” of five (5) years each with respect to all (or such lesser portion of the Facilities as provided below) of the Facilities that are subject to the Master Lease as of the last day of the then current Term at a Rent being equal to the Renewal Rent if (a) at least twenty four (24) months prior to the end of the then current Term (a “ Renewal Election Outside Date ”), Tenant delivers to Landlord a “ Renewal Notice ” stating that it exercises its right to extend this Master Lease for one (1) Renewal Term and (b) no Event of Default shall have occurred and be continuing on the Renewal Election Outside Date. If, Tenant elects to renew the Lease for less than all of the Facilities, then Tenant must specify in the Renewal Notice which Facilities it elects not to renew (each a “ Non-Renewal Leased Property ” and collectively, the “ Non-Renewal Leased Properties ”). Any Facilities not specified in the Renewal Notice as Non-Renewal Leased Properties shall be deemed to be part of the Leased Property that has been extended for the one (1) Renewal Term (each a “ Renewal Leased Property ” and collectively, the “ Renewal Leased Properties ”). During any such Renewal Term, except as otherwise specifically provided for herein, all of the terms and conditions of this Master Lease shall remain in full force and effect, except that the Non-Renewal Leased Properties shall be excluded from the definition of “ Leased Property ” for the applicable Renewal Term, and Tenant shall have no further renewal rights with respect to the Non-Renewal Leased Properties. If Tenant does not timely send the applicable Renewal Notice pursuant to the provisions of this Section 1.4, Tenant shall be deemed to have irrevocably waived its renewal rights for all subsequent Renewal Terms.

(b) No later than two hundred ten (210) days prior to the Renewal Election Outside Date for each Renewal Term, Landlord shall deliver a Notice to Tenant which sets forth

3

Landlord’s proposal of the Renewal Rent and Successor Tenant Rent, in each case, for each Facility then subject to this Master Lease.

ARTICLE III

3.1 Rent . During the Term, Tenant will pay to Landlord (or as otherwise directed by Landlord pursuant to Section 3.3 or as otherwise provided in Sections 4.1 and 4.2) the Rent and Additional Charges in lawful money of the United States of America and legal tender for the payment of public and private debts, in the manner provided in Section 3.3. The Rent during any Lease Year is payable in advance in consecutive monthly installments on the fifth (5 ^th ) Business Day of each calendar month during that Lease Year. Unless otherwise agreed by the parties, Rent and Additional Charges shall be prorated as to any partial months at the beginning and end of the Term.

3.2 Late Payment of Rent and Additional Charges . Tenant hereby acknowledges that late payment by Tenant to Landlord of Rent and Additional Charges will cause Landlord to incur costs not contemplated hereunder, the exact amount of which is presently anticipated to be extremely difficult to ascertain. Accordingly, if any installment of Rent and Additional Charges (other than Additional Charges payable to a Person other than Landlord) shall not be paid within ten (10) days after its due date, Tenant will pay Landlord on demand a late charge equal to the lesser of (a) five percent (5%) of the amount of such installment or (b) the maximum amount permitted by law. The parties agree that this late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of late payment by Tenant. The parties further agree that such late charge is an Additional Charge and not interest and such assessment does not constitute a lender or borrower/creditor relationship between Landlord and Tenant. Thereafter, if

27

any installment of Rent or an Additional Charge (other than Additional Charges payable to a Person other than Landlord) shall not be paid within fifteen (15) days after its due date, the amount unpaid, including any late charges previously accrued, shall bear interest at the Overdue Rate from the due date of such installment to the date of payment thereof, and Tenant shall pay such interest to Landlord on demand. The payment of such late charge or such interest shall not constitute waiver of, nor excuse or cure, any default under this Master Lease, nor prevent Landlord from exercising any other rights and remedies available to Landlord.

3.3 Method of Payment of Rent and Additional Charges to Landlord .

(a) Rent and Additional Charges to be paid to Landlord shall be paid by electronic funds transfer debit transactions through wire transfer of immediately available funds and shall be initiated by Tenant for settlement on or before the Payment Date; provided , however , if the Payment Date is not a Business Day, then settlement shall be made on the next succeeding day which is a Business Day. Landlord shall provide Tenant with appropriate wire transfer information in a Notice from Landlord to Tenant. Landlord shall deliver an invoice to Tenant (each an “ Additional Charge Invoice ”) no later than twenty (20) days after the end of each calendar month which itemizes the Additional Charges that Tenant is obligated to pay to Landlord. Promptly following Tenant’s request, Landlord shall provide such documentation as reasonably requested by Tenant to enable Tenant to verify the accuracy of the Additional Charges set forth on the Additional Charge Invoice. Subject to Section 3.3(b) and Article XII relating to permitted contests, Tenant shall pay all Additional Charges to Landlord (or to such other person directed by Landlord) within thirty (30) days after Landlord delivers the Additional Charge Invoice therefor.

(b) No later than fifteen (15) days after the end of each calendar month, Tenant shall deliver to Landlord a report (each a “ Monthly Report ”) setting forth all Additional Charges paid by Tenant during the immediately preceding calendar month. Landlord shall reasonably cooperate with Tenant in the preparation of such Monthly Report. Promptly following Landlord’s request, Tenant shall deliver to Landlord such documentation as reasonably requested by Landlord, including, without limitation, a copy of the transmittal letter or invoice and a check whereby such payment was made, to evidence the proper payment of the Additional Charges by Tenant to parties other than Landlord hereunder.

(c) Either Landlord or Tenant (the “ Auditing Party ”), upon Notice delivered to the other party (the “ Audited Party ”) within sixty (60) days after the end of each calendar year, may elect to have a certified accountant from a nationally recognized accounting firm designated by the Auditing Party to audit the books and records of the Audited Party relating to the Additional Charge Invoices or Monthly Reports, as applicable, for the immediately preceding calendar year, together with reasonable supporting data therefor, such audit to occur during business hours and with at least Five (5) Business Days’ prior notice to the Audited Party, and which shall commence no later than thirty (30) days following the date of the Auditing Party’s Notice, as such date may be extended on a day for day basis to the extent the Audited Party delays the Audited Party’s access to such books and records following the request therefor. If Landlord or Tenant fails to deliver Notice within the time period stated above, then the Additional Charge Invoices or Monthly Reports, as applicable, for the immediately preceding calendar year shall be deemed conclusive and binding upon such party.

28

(d) The Auditing Party and the Auditing Party’s employees, accountants and agents shall treat all of the Audited Party’s books and records, and any analysis thereof, as confidential, and, as a condition to any review of such books and records, the Auditing Party shall confirm such confidentiality obligation in writing by executing a confidentiality agreement in form and substance reasonably acceptable to Landlord and Tenant. The Auditing Party shall, at the Auditing Party’s sole cost and expense, have the right to obtain copies and/or make abstracts of the books and records as it may reasonably request in connection with its verification of any such Additional Charge Invoices and/or the Monthly Reports, subject to the provisions of any such confidentiality agreement.

(e) Pending the determination of any dispute, Tenant shall pay all Additional Charges required to be paid in accordance with the Additional Charge Invoices in question; provided that the payment of such Additional Charges shall be without prejudice to Tenant’s right to dispute such amounts or Tenant’s right to recover if Tenant successfully challenges the Additional Charge Invoices. After the dispute has been finally resolved and it is determined that Landlord overstated the Additional Charges on the Additional Charge Invoices in question, then (i) Landlord shall refund to Tenant the amount of such overpayment together with interest thereon at the Overdue Rate no later than thirty (30) days following such determination and (ii) if it is determined that Tenant has overpaid such Additional Charges by more than five percent (5%), Landlord shall reimburse Tenant for Tenant’s reasonable auditing fees incurred in connection with such determination no later than thirty (30) days following receipt of an invoice therefor (with reasonable backup) from Tenant. Landlord’s obligation to make such payment shall survive the expiration or earlier termination of this Master Lease.

(f) After a dispute has been finally resolved and it is determined that Tenant has underpaid any Additional Charges (to a party other than Landlord) based on the Landlord’s audit set forth in this Section 3.3, Tenant shall pay the amount of such underpayment to the applicable party (together with all applicable interest and penalties related thereto) within thirty (30) days following such determination and shall send to Landlord, simultaneously with such payment, a copy of the invoice or check or other evidence of payment therefor. If it is determined that Tenant has underpaid such Additional Charges by more than five percent (5%), Tenant shall reimburse Landlord for Landlord’s reasonable auditing fees incurred in connection with such determination no later than thirty (30) days following receipt of an invoice therefor (with reasonable backup) from Landlord. Tenant’s obligation to make such payment shall survive the expiration or earlier termination of this Master Lease.

3.4 Net Lease . Landlord and Tenant acknowledge and agree that (i) this Master Lease is and is intended to be what is commonly referred to as a “net, net, net” or “triple net” lease, and (ii) the Rent shall be paid absolutely net to Landlord, so that this Master Lease shall yield to Landlord the full amount or benefit of the installments of Rent and Additional Charges throughout the Term with respect to each Facility subject to this Master Lease from time to time, all as more fully set forth in Article IV and subject to any other provisions of this Master Lease which expressly provide for adjustment or abatement of Rent or other charges. If Landlord commences any proceedings for non-payment of Rent or Additional Charges, Tenant will not interpose any counterclaim or cross complaint or similar pleading of any nature or description in such proceedings unless Tenant would lose or waive such claim by the failure to assert it. This shall not, however, be construed as a waiver of Tenant’s right to assert such claims in a separate action

29

brought by Tenant. The covenants to pay Rent and other amounts hereunder are independent covenants, and Tenant shall have no right to hold back, offset or fail to pay any such amounts for default by Landlord or for any other reason whatsoever. Notwithstanding anything to the contrary contained herein, in the event Landlord defaults on its obligation to fund a Capital Improvement pursuant to Section 10.2(b) and such failure is not cured by Landlord within thirty (30) days following receipt of Notice from Tenant of Landlord’s failure to make such payment, Tenant shall be entitled to offset against the next subsequent payments of Rent the amount that Landlord was obligated to but failed to fund to Tenant with respect to such Capital Improvement under Section 10.2.

ARTICLE IV

4.1 Impositions . (a) Subject to Article XII relating to permitted contests, and without any duplication as to amounts payable by Tenant as Additional Charges to Landlord, Tenant shall pay, or cause to be paid, all Impositions before any fine, penalty, interest or cost may be added for non-payment. Tenant shall make such payments directly to the taxing authorities or such other third parties where feasible. Tenant’s obligation to pay Impositions shall be absolutely fixed upon the date such Impositions become a Lien upon the Leased Property or any part thereof subject to Article XII. If any Imposition may, at the option of the taxpayer, lawfully be paid in installments, whether or not interest shall accrue on the unpaid balance of such Imposition, Tenant may pay the same, and any accrued interest on the unpaid balance of such Imposition, in installments as the same respectively become due and before any fine, penalty, premium, further interest or cost may be added thereto.

(b) Landlord shall prepare and file all tax returns and reports as may be required by Legal Requirements with respect to Landlord’s net income, gross receipts, franchise taxes and taxes on its capital stock and any other returns required to be filed by or in the name of Landlord (the “ Landlord Tax Returns ”), and Tenant shall prepare and file all other tax returns and reports as may be required by Legal Requirements with respect to or relating to the Leased Property (including all Capital Improvements), and Tenant’s Property. For the avoidance of doubt, to facilitate administrative efficiency and to mitigate the risk of duplication of tasks and double-taxation on assets that are on the books and records of Landlord and Tenant, Tenant shall file all tax returns and reports required by any Legal Requirements with respect to or relating to the Leased Property, the Capital Improvements, and Tenant’s Property except to the extent Landlord is required (and Tenant is not otherwise permitted) to make such filing, in which case Landlord shall make such filing following Notice thereof from Tenant.

(c) Any refund due from any taxing authority in respect of any Imposition paid by or on behalf of Tenant on or after the date of this Master Lease or in respect of any period prior to the Commencement Date shall be paid over to or retained by Tenant. If Landlord receives such refund from the taxing authority, Landlord shall pay such refund over to Tenant no later than thirty (30) days after receipt of such refund by Landlord.

(d) Landlord and Tenant shall, upon request of the other, provide such data as is maintained by the party to whom the request is made with respect to the Leased Property as may be necessary to prepare any required tax returns and reports. For any property covered by this Master Lease that is real property or personal property for tax purposes, Tenant shall file all

30

property tax returns in such jurisdictions where it must legally so file. Landlord, to the extent it possesses the same, and Tenant, to the extent it possesses the same, shall provide the other party, upon request, with cost and depreciation records necessary for filing returns for any property required to be reported hereunder. Where Landlord is legally required to file property tax returns, Tenant shall be provided with copies of assessment notices indicating a value in excess of the reported value in sufficient time for Tenant to file a protest.

(e) Billings for reimbursement by Tenant to Landlord of personal property or real property taxes and any taxes due under the Landlord Tax Returns, if and to the extent Tenant is responsible for such taxes under the terms of this Section 4.1, shall be accompanied by copies of a bill therefor and payments thereof which identify the personal property or real property or other tax obligations of Landlord with respect to which such payments are made.

(f) Impositions imposed or assessed in respect of the tax-fiscal period during which the Term terminates shall be adjusted and prorated between Landlord and Tenant, whether or not such Imposition is imposed or assessed before or after such termination, and Tenant’s obligation to pay its prorated share thereof in respect of a tax-fiscal period during the Term shall survive such termination. Landlord will not voluntarily enter into agreements that will result in additional Impositions without Tenant’s consent, which shall not be unreasonably withheld (it being understood that it shall not be reasonable to withhold consent to customary additional Impositions that other property owners of properties similar to the Leased Property customarily consent to in the ordinary course of business); provided Tenant is given reasonable opportunity to participate in the process leading to such agreement.

4.2 Utilities . Without duplication of any amounts payable by Tenant as Additional Charges to Landlord under Article III, Tenant shall pay or cause to be paid all charges for electricity, power, gas, oil, water and other utilities used in the Leased Property (including all Capital Improvements). Tenant shall also pay or reimburse Landlord in accordance with Article III for all costs and expenses of any kind whatsoever which at any time with respect to the Term hereof with respect to any Facility may be imposed against Landlord by reason of any of the covenants, conditions and/or restrictions affecting the Leased Property or any portion thereof, or with respect to easements, licenses or other rights over, across or with respect to any adjacent or other property which benefits the Leased Property, or any Capital Improvement. Landlord will not enter into any such agreements without Tenant’s consent, which shall not be unreasonably withheld (it being understood that it shall not be reasonable to withhold consent to such agreements that do not adversely affect the use or future development of the Facility as a Communications Facility or increase Additional Charges payable under this Master Lease). Tenant will not enter into agreements that will encumber the Leased Property after the expiration of the Term without Landlord’s consent, which shall not be unreasonably withheld (it being understood that it shall not be reasonable to withhold consent to Encumbrances that do not adversely affect the value of the Leased Property or the Facility); provided Landlord is given reasonable opportunity to participate in the process leading to such agreement.

4.3 Impound Account . At Landlord’s option following the occurrence and during the continuation of an Event of Default (to be exercised by thirty (30) days’ Notice to Tenant), Tenant shall be required to deposit, at the time of any payment of Rent, an amount equal to one-twelfth of the sum of (i) Tenant’s estimated annual real and personal property taxes required

31

pursuant to Section 4.1 hereof (as reasonably determined by Landlord), and (ii) Tenant’s estimated annual maintenance expenses and insurance premium costs pursuant to Articles IX and Article XIII hereof (as reasonably determined by Landlord). Such amounts shall be applied to the payment of the obligations in respect of which said amounts were deposited in such order of priority as Landlord shall reasonably determine, on or before the respective dates on which the same or any of them would become delinquent. The reasonable cost of administering such impound account shall be paid by Tenant. Nothing in this Section 4.3 shall be deemed to affect any right or remedy of Landlord hereunder.

ARTICLE V

5.1 No Termination, Abatement, etc . Except as otherwise specifically provided in this Master Lease including, without limitation, Section 3.4, Tenant shall remain bound by this Master Lease in accordance with its terms and shall not seek or be entitled to any abatement, deduction, deferment or reduction of Rent, or set-off against the Rent. Except as may be otherwise specifically provided in this Master Lease, the respective obligations of Landlord and Tenant shall not be affected by reason of (i) any damage to or destruction of the Leased Property or any portion thereof from whatever cause or any Condemnation of the Leased Property, any Capital Improvement or any portion thereof; (ii) other than as a result of Landlord’s willful misconduct or gross negligence, the lawful or unlawful prohibition of, or restriction upon, Tenant’s use of the Leased Property, any Capital Improvement or any portion thereof, the interference with such use by any Person or by reason of eviction by paramount title; (iii) any claim that Tenant has or might have against Landlord by reason of any default or breach of any warranty by Landlord hereunder or under any other agreement between Landlord and Tenant or to which Landlord and Tenant are parties; (iv) any bankruptcy, insolvency, reorganization, consolidation, readjustment, liquidation, dissolution, winding up or other proceedings affecting Landlord or any assignee or transferee of Landlord; or (v) for any other cause, whether similar or dissimilar to any of the foregoing, other than a discharge of Tenant from any such obligations as a matter of law. Tenant hereby specifically waives all rights arising from any occurrence whatsoever which may now or hereafter be conferred upon it by law (a) to modify, surrender or terminate this Master Lease or quit or surrender the Leased Property or any portion thereof, or (b) which may entitle Tenant to any abatement, reduction, suspension or deferment of the Rent or other sums payable by Tenant hereunder except in each case as may be otherwise specifically provided in this Master Lease. Notwithstanding the foregoing, nothing in this Article V shall preclude Tenant from bringing a separate action against Landlord for any matter described in the foregoing clauses (ii), (iii) or (v), and Tenant is not waiving other rights and remedies not expressly waived herein. The obligations of Landlord and Tenant hereunder shall be separate and independent covenants and agreements and the Rent and all other sums payable by Tenant hereunder shall continue to be payable in all events unless the obligations to pay the same shall be terminated pursuant to the express provisions of this Master Lease or by termination of this Master Lease as to all or any portion of the Leased Property other than by reason of an Event of Default. Tenant’s agreement that, except as may be otherwise specifically provided in this Master Lease, any eviction by paramount title as described in item (ii) above shall not affect Tenant’s obligations under this Master Lease, shall not in any way discharge or diminish any obligation of any insurer under any policy of title or other insurance and, to the extent the recovery thereof is not necessary to compensate Landlord for any damages incurred by any such eviction, Tenant shall be entitled to a credit for any sums recovered by Landlord under any such

32

policy of title or other insurance up to the maximum amount paid by Tenant to Landlord under this Section 5.1, and Landlord, upon request by Tenant, shall assign Landlord’s rights under such policies to Tenant; provided that such assignment does not adversely affect Landlord’s rights under any such policy and provided further , that Tenant shall indemnify, defend, protect and save Landlord harmless from and against any liability, cost or expense of any kind that may be imposed upon Landlord in connection with any such assignment except to the extent such liability, cost or expense arises from the gross negligence or willful misconduct of Landlord.

ARTICLE VI

6.1 Ownership of the Leased Property . (a) Landlord and Tenant acknowledge and agree that they have executed and delivered this Master Lease with the understanding that (i) the Leased Property is the property of Landlord, (ii) Tenant has only the right to the possession and use of the Leased Property upon the terms and conditions of this Master Lease, (iii) this Master Lease is a “true lease,” is not a financing lease, capital lease, mortgage, equitable mortgage, deed of trust, trust agreement, security agreement or other financing or trust arrangement, and the economic realities of this Master Lease are those of a true lease, (iv) the business relationship created by this Master Lease and any related documents is and at all times shall remain that of landlord and tenant, (v) this Master Lease has been entered into by each party in reliance upon the mutual covenants, conditions and agreements contained herein, and (vi) none of the agreements contained herein is intended, nor shall the same be deemed or construed, to create a partnership between Landlord and Tenant, to make them joint venturers, to make Tenant an Affiliate, agent, legal representative, partner, subsidiary or employee of Landlord, or to make Landlord in any way responsible for the debts, obligations or losses of Tenant.

(b) Each of the parties hereto covenants and agrees, subject to Section 6.1(c), not to (i) file any income tax return or other associated documents; (ii) file any other document with or submit any document to any governmental body or authority; (iii) enter into any written contractual arrangement with any Person; or (iv) release any financial statements of Tenant, in each case that takes a position for tax purposes other than that this Master Lease is a “true lease” with Landlord as owner of the Leased Property and Tenant as the tenant of the Leased Property, including (x) treating Landlord as the owner of such Leased Property eligible to claim depreciation deductions under Sections 167 or 168 of the Code with respect to such Leased Property, (y) Tenant reporting its Rent payments as rent expense under Section 162 of the Code, and (z) Landlord reporting the Rent payments as rental income under Section 61 of the Code.

(c) If Tenant should reasonably conclude that GAAP, the SEC or the Communications Regulations require treatment different from that set forth in Section 6.1(b) for applicable non-tax purposes, then (x) Tenant shall promptly give prior Notice to Landlord, accompanied by a written statement that references the applicable pronouncement that controls such treatment and contains a brief description and/or analysis that sets forth in reasonable detail the basis upon which Tenant reached such conclusion, and (y) notwithstanding Section 6.1(b), Tenant may comply with such requirements.

(d) The Rent is the fair market rent for the use of the Leased Property and was agreed to by Landlord and Tenant on that basis, and the execution and delivery of, and the performance by Tenant of its obligations under, this Master Lease does not constitute a transfer of all or any part of the Leased Property.

33

(e) Tenant waives any claim or defense based upon the characterization of this Master Lease as anything other than a true lease and as a master lease of all of the Leased Property. Tenant stipulates and agrees (1) not to challenge the validity, enforceability or characterization of the lease of the Leased Property as a true lease and/or as a single, unseverable instrument pertaining to the lease of all, but not less than all, of the Leased Property, and (2) not to assert or take or omit to take any action inconsistent with the agreements and understandings set forth in Section 3.4 or this Section 6.1.

6.2 Tenant’s Property . During the entire Term, Tenant (and Tenant’s Subsidiaries) shall have the right to affix any Electronics and other equipment to the Distribution Systems in order to operate the Facilities for the Primary Intended Use. Tenant shall maintain (or cause Tenant’s Subsidiaries to maintain) all of such Tenant’s Property in accordance with Prudent Industry Practice, in all cases as shall be necessary and appropriate in order to operate the Facilities for the Primary Intended Use in compliance in all material respects with all applicable licensure and certification requirements and in compliance in all material respects with all applicable Legal Requirements, Insurance Requirements, Permits and Communications Regulations. If any of Tenant’s Property requires replacement in order to comply with the foregoing, Tenant shall replace (or cause Tenant’s Subsidiary to replace) it with similar property in a manner consistent with Prudent Industry Practice at Tenant’s (or such Subsidiary’s) sole cost and expense. Subject to the foregoing, Tenant and Tenant’s Subsidiaries may sell, transfer, convey, pledge or otherwise dispose of Tenant’s Property (other than the Communications Licenses) in their discretion in the ordinary course of their business and Landlord shall have no rights to such Tenant’s Property, provided however any pledge of Tenant’s Property (including any Communications Licenses), any TCI ILEC Extensions and any TCI CLEC Extensions by Tenant as collateral shall be subject to Tenant’s obligation to transfer the Tenant’s Property and such TCI ILEC Extensions and TCI CLEC Extensions to a Successor Tenant pursuant to Article XXXVI free and clear of any Encumbrances but only to the extent the same constitute Communication Assets. In the case of any such Tenant’s Property that is leased (rather than owned) by Tenant (or its Subsidiaries), Tenant shall use commercially reasonable efforts to ensure that the lease agreements pursuant to which Tenant (or its Subsidiaries) leases such Tenant’s Property are assignable to third parties in connection with any transfer by Tenant (or its Subsidiaries) to a replacement lessee or operator at the end of the Term. Tenant shall remove all of Tenant’s Property from the Leased Property at the end of the Term, except to the extent Tenant has transferred ownership of such Tenant’s Property to a Successor Tenant or Landlord or Tenant continues to operate the Leased Property under a Management Agreement. Any Tenant’s Property left on the Leased Property at the end of the Term whose ownership was not transferred to a Successor Tenant shall be deemed abandoned by Tenant and shall become the property of Landlord.

ARTICLE VII

7.1 Condition of the Leased Property . Tenant acknowledges receipt and delivery of possession of the Leased Property and confirms that Tenant has examined and otherwise has knowledge of the condition of the Leased Property prior to the execution and delivery of this

34

Master Lease and has found the same to be in good order and repair and, to the best of Tenant’s knowledge, free from Hazardous Substances not in compliance with Legal Requirements and satisfactory for its purposes hereunder. Regardless, however, of any examination or inspection made by Tenant and whether or not any patent or latent defect or condition was revealed or discovered thereby, Tenant is leasing the Leased Property “as is” in its present condition. Tenant waives any claim or action against Landlord in respect of the condition of the Leased Property including any defects or adverse conditions not discovered or otherwise known by Tenant as of the Commencement Date. LANDLORD MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, IN RESPECT OF THE LEASED PROPERTY OR ANY PART THEREOF, EITHER AS TO ITS FITNESS FOR USE, DESIGN OR CONDITION FOR ANY PARTICULAR USE OR PURPOSE OR OTHERWISE, OR AS TO THE NATURE OR QUALITY OF THE MATERIAL OR WORKMANSHIP THEREIN, OR THE EXISTENCE OF ANY HAZARDOUS SUBSTANCE, IT BEING AGREED THAT ALL SUCH RISKS, LATENT OR PATENT, ARE TO BE BORNE SOLELY BY TENANT INCLUDING ALL RESPONSIBILITY AND LIABILITY FOR ANY ENVIRONMENTAL REMEDIATION AND COMPLIANCE WITH ALL ENVIRONMENTAL LAWS.

7.2 Use of the Leased Property . (a) Throughout the Term of this Master Lease, Tenant shall have the exclusive right to use, or cause to be used, the Leased Property of each Facility for its Primary Intended Use; it being agreed and acknowledged by Landlord that any of Tenant’s Subsidiaries (including but not limited to the Subsidiaries set forth on Schedule 7.2 attached hereto) shall have the right to use, occupy and operate the Leased Property subject to and in accordance with the terms of this Master Lease and such Subsidiaries shall have the right to discharge any or all of Tenant’s obligations (maintenance or otherwise) hereunder on behalf of Tenant. Tenant shall not use the Leased Property or any portion thereof or any Capital Improvement thereto for any other use without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed.

(b) Tenant shall not commit or suffer to be committed any waste on the Leased Property (including any Capital Improvement thereto) or cause or permit any nuisance thereon or to, except as required by law, take or suffer any action or condition that will diminish the ability of the Leased Property to be used as a Communications Facility after the expiration or earlier termination of the Term.

(c) Tenant shall neither suffer nor permit the Leased Property or any portion thereof to be used in such a manner as (i) might reasonably tend to impair Landlord’s title thereto or to any portion thereof or (ii) may make possible a claim of adverse use or possession, or an implied dedication of the Leased Property or any portion thereof.

(d) Except in instances of casualty or condemnation, Tenant shall continuously operate each of the Facilities for one or more of the activities constituting the Primary Intended Use, with the specific use conducted at any portion of the Facilities to be determined by Tenant in its reasonable discretion. Notwithstanding the foregoing, Tenant in its discretion shall be permitted to cease operations at a Facility or Facilities if such cessation would either (x) not reduce the route miles of the fiber optic and copper cable lines with respect to any one Facility by more than ten percent (10%) or the Facilities as a whole by more than five percent (5%) in the aggregate over the Term or (y) not reasonably be expected to have a material

35

adverse effect on Tenant, the Facilities, or on the Leased Property, taken as a whole, provided that no Event of Default has occurred and is continuing immediately prior to or immediately after the date that operations are ceased or as a result of such cessation and such cessation does not result in any non-compliance with any Legal Requirements, Communications Licenses, Pole Agreements or Communications Regulations.

Notwithstanding the foregoing, upon the occurrence and during the continuance of an Event of Default that is monetary in nature, Landlord shall have the right to receive all rents, profits and charges arising from any sublease of the Leased Property (including, but not limited to, any rights granted pursuant to a dark fiber agreement, a dim fiber agreement or a collocation agreement) subject to applicable law, and apply such rents, profits and charges to Rent as set forth in Section 22.3.

40

respect to the Leased Property and (iv) Landlord shall continue to hold the beneficial ownership interests in such modified Permits or Pole Agreements and legal title to such modified Permits or Pole Agreements shall revert to Landlord at the end of the Term for the applicable Facility.

In the event of an adverse final determination with respect to any such encroachment, violation or impairment, either (a) each of Tenant and Landlord shall be entitled to obtain valid and effective waivers or settlements of all claims, liabilities and damages resulting from each such encroachment, violation or impairment, whether the same shall affect Landlord or Tenant or (b) Tenant at the shared cost and expense of Tenant and Landlord on a 50-50 basis shall make such changes in the Leased Improvements, and take such other actions, as Tenant in the good faith exercise of its judgment deems reasonably practicable, to remove such encroachment or to end such violation

or impairment, including, if necessary, the alteration of any of the Leased Improvements, and in any event take all such actions as may be necessary in order to be able to continue the operation of the Leased Improvements for the Primary Intended Use substantially in the manner and to the extent the Leased Improvements were operated prior to the assertion of such encroachment, violation or impairment.

(b) Tenant’s (and Landlord’s) obligations under this Section 9.3 shall be in addition to and shall in no way discharge or diminish any obligation of any insurer under any policy of title or other insurance and, to the extent the recovery thereof is not necessary to compensate Landlord and Tenant for any damages incurred by any such encroachment, violation or impairment, Tenant shall be entitled to fifty percent (50%) of any sums recovered by Landlord under any such policy of title or other insurance up to the maximum amount paid by Tenant under this Section 9.3 and Landlord, upon request by Tenant, shall assign Landlord’s rights under such policies to Tenant; provided such assignment does not adversely affect Landlord’s rights under any such policy.

ARTICLE X

10.1 Construction of Capital Improvements to the Leased Property . Tenant shall, with respect to any Facility, have the right to make a Capital Improvement, including, without limitation, any Capital Improvement required by Section 8.2 or 9.1(a), without the consent of Landlord if the Capital Improvement is constructed in accordance with the Engineering Standard. Tenant shall have the right to modify the Engineering Standard from time to time subject to Landlord’s consent, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, Tenant shall have the right, without Landlord’s consent, to modify the Engineering Standard as long as the modification is consistent with prevailing industry practice and is in compliance with applicable Legal Requirements. All Capital Improvements that do not comply with the Engineering Standard shall be subject to Landlord’s review and approval, which approval shall not be unreasonably withheld. If Tenant desires to make a Capital Improvement for which Landlord’s approval is required, Tenant shall submit to Landlord in reasonable detail a general description of the proposal, the projected cost of construction and such plans and specifications, permits, licenses, contracts and other information concerning the proposal as Landlord may reasonably request. It shall be reasonable for Landlord to condition its approval of any Capital Improvement upon any or all of the following terms and conditions:

(a) Such construction shall be effected pursuant to detailed plans and specifications approved by Landlord (such approval not to be unreasonably withheld) for the Capital Improvements in which detailed plans and specifications are customarily prepared;

43

(b) Such construction shall be conducted under the supervision of an architect or engineer selected by Tenant and approved by Landlord, which approval shall not be unreasonably withheld; and

(c) No Capital Improvement will result in the Leased Property becoming a “limited use” property for purposes of United States federal income taxes.

10.2 Landlord’s Funding of Capital Improvements .

(a) No later than November 15 ^th of each calendar year, Tenant shall furnish to Landlord a report of Capital Improvements planned for each Facility for the immediately following calendar year (such report, the “ Annual Capital Improvement Plan ”) that Tenant seeks Landlord to finance (in whole or in part), which report shall set forth in reasonable detail the plans, specifications, budget, the amount of financing that Tenant is requesting from Landlord (the “ Requested Funding Amount ”), along with the construction and/or acquisition schedule for such Capital Improvements. No later than twenty (20) days following Landlord’s receipt of the Annual Capital Improvement Plan, Landlord and Tenant shall cause their representatives (including a Financial Officer and an engineer for each of Landlord and Tenant) to meet at Landlord’s office in order to discuss the Annual Capital Improvement Plan.

(b) Within thirty (30) days from the date of such meeting (the “ Outside Date ”), Landlord shall notify Tenant whether it will fund all or a portion of the Requested Funding Amount and the terms and conditions on which it would do so. Notwithstanding the foregoing but subject to the terms of this Section 10.2(b), in the event either (i) Tenant exercises the Initial Extension Right in accordance with Section 1.3, and in connection therewith, Landlord agrees to provide the Full Funding Commitment in accordance with this Section 10.2(b), or (ii) Tenant is deemed not to have exercised the Initial Extension Right in accordance with Section 1.3 but Landlord agrees to provide a Limited Funding Commitment in accordance with this Section 10.2(b), then, in either case, commencing with the Lease Year immediately following Landlord’s receipt of the Initial Extension Notice and continuing for a maximum period of five (5) consecutive Lease Years (or such shorter period as hereinafter provided), Landlord agrees to pay to Tenant, taking into account any prior payments made by Landlord to Tenant under this Section 10.2 during the applicable Lease Year, an amount equal to the actual costs paid by or on behalf of Tenant in the performance of the applicable Capital Improvement that is the subject of the Requested Funding Amount until the Full Funding Commitment or Limited Funding Commitment, as applicable, for such Lease Year has been fully depleted. Notwithstanding anything to the contrary contained herein, in no event shall Landlord have any obligation to provide funding to Tenant as a Full Funding Commitment or Limited Funding Commitment, as applicable, or otherwise for any Requested Funding Amounts from and after the seventh (7 ^th ) anniversary of the Commencement Date. If Landlord is required to fund any portion of a Capital Improvement pursuant to the terms hereof or otherwise agrees to provide funding for any portion of a Capital Improvement, including as a Full Funding Commitment or Limited Funding Commitment, at any time prior to the second (2 ^nd ) anniversary of the Commencement Date, the then current annual Rent under this Master Lease shall be increased, effective as of the date of such funding and continuing for the balance of the Initial Term, by an amount equal to the product of (i) the amount of the funds advanced by Landlord to Tenant for such Capital Improvement on such date multiplied by (ii) 8.125% (the “ Annual Base Increase Amount ”). For the avoidance of doubt, if Landlord provides funding to Tenant for a Capital Improvement in the amount of $30,000,000 prior to the second (2 ^nd )

44

anniversary of the Commencement Date, the annual Rent shall be increased by an amount equal to $2,437,500 effective as of the date such funds are advanced by Landlord to Tenant but subject to proration for the Lease Year in which the funding occurs based on the number of calendar months remaining in such Lease Year from and after the date that the funds are advanced. Such annual Rent as so increased by the Annual Base Increase Amount shall remain in effect until any subsequent increase pursuant to this Section 10.2 and shall be paid in the manner provided in Article III. If Landlord is required to fund any portion of a Capital Improvement pursuant to the terms hereof or otherwise agrees to provide funding for any portion of a Capital Improvement from and after the second (2 ^nd ) anniversary of the Commencement Date and through and excluding the seventh (7 ^th ) anniversary of the Commencement Date, the then current annual Rent under this Master Lease shall be increased, effective as of the date of such funding and continuing for the balance of the Initial Term, by an amount equal to the product of (i) the amount of the funds advanced by Landlord to Tenant for such Capital Improvement on such date multiplied by (ii) a capitalization rate not to exceed two hundred (200) basis points above the average of Landlord’s highest cost of debt’s average implied yield over the preceding sixty (60) trading days and Landlord’s average implied dividend yield over the preceding sixty (60) trading days. Within thirty (30) days after the Commencement Date, the parties will document the operating procedures for the funding of Capital Improvements, including, without limitation, the issuance of funding requests by Tenant, the due date for Landlord to disburse funds to Tenant, and the dispute resolution provisions. If Landlord fails to notify Tenant of its election to fund all or a portion of the Requested Funding Amount by the Outside Date or Landlord and Tenant fail to agree to on the terms and conditions by which Landlord will fund the Requested Funding Amount by the Outside Date and such Requested Funding Amount is in excess of the Full Funding Commitment or Limited Funding Commitment, as applicable, for any Lease Year in which Landlord is obligated to provide a Funding Commitment or otherwise relates to a Capital Improvement during any Lease Year in which Landlord has no obligation to provide a Funding Commitment hereunder, Landlord shall be deemed to have declined to fund the Requested Funding Amount. In no event shall Tenant’s obligations under Article VIII and IX of this Master Lease be reduced or modified in any manner as a result of Landlord declining to provide the Requested Funding Amount for a Capital Improvement and such Requested Funding Amount is in excess of the Funding Commitment for any Lease Year in which Landlord agreed to provide a Funding Commitment or otherwise relates to a Capital Improvement to be constructed during any Lease Year in which Landlord has not agreed to provide a Funding Commitment hereunder.

(c) If Tenant constructs a Capital Improvement that is not funded by Landlord (each a “ Tenant Capital Improvement ”) and the Capital Improvement constitutes maintenance, repair, overbuild, upgrade or replacement of the Leased Property, including, without limitation, the replacement of copper distribution systems with fiber distribution systems (each a “ TCI Replacement ”), then such TCI Replacement shall automatically become a part of the Leased Property. If a Tenant Capital Improvement constitutes an Extension of the Distribution Systems to a New Geographic Area where Tenant or its Subsidiaries are licensed as an incumbent local exchange carrier (each a “ TCI ILEC Extension ”), then Tenant shall receive fair value for such TCI ILEC Extension by having such TCI ILEC Extension included as part of the Communication Assets sold under Article XXXVI. If the Tenant Capital Improvement occurs where Tenant or its Subsidiaries are a competitive local exchange carrier and is not a TCI Replacement (each a “ TCI CLEC Extension ”), then Tenant may elect to remove the connections between the TCI CLEC

45

Extension and the Leased Property or, if the connection between the TCI CLEC Extension and the Leased Property is functionally independent, elect to leave such connection in place by delivering Notice of either such election to Landlord (which Notice shall also indicate Tenant’s intent to enter into an interconnection agreement with the Successor Tenant for continuing access to the Leased Property and shall be delivered no later than (x) fifteen (15) days after the Renewal Election Outside Date in the case of the expiration of the Term or (y) thirty (30) days following receipt of the Lease Termination Notice in the case of the termination of the Term, as applicable) and such TCI CLEC Extension will be Tenant’s Property. If the connection between the TCI CLEC Extension and the Leased Property is not functionally independent and Tenant elects not to remove the TCI CLEC Extension connections or Notice is not timely delivered to Landlord, then Tenant shall receive fair value for such TCI CLEC Extension by having such TCI CLEC Extension included as part of the Communication Assets sold under Article XXXVI. If Tenant elects to remove the connections between any TCI CLEC Extension and the Leased Property pursuant to the terms of this Section 10.2(c), the Leased Property following such removal shall be restored in accordance with Prudent Industry Practice.

(d) If Landlord funds a Capital Improvement in accordance with the terms of this Section 10.2, such Capital Improvement shall be deemed a part of the Leased Property and the Facilities for all purposes and Tenant shall provide Landlord with the following within time periods agreed upon by Landlord and Tenant:

(i) any information, certificates, licenses, new Permits or Pole Agreements or documents reasonably requested by Landlord which are necessary and obtainable to confirm that Tenant will be able to use the Capital Improvement upon completion thereof in accordance with the Primary Intended Use;

(ii) an Officer’s Certificate setting forth in reasonable detail the projected or actual costs related to such Capital Improvement;

(iii) an amendment to this Master Lease (and any development or funding agreement agreed to in accordance with this Section 10.2), in a form reasonably agreed to by Landlord and Tenant, which may include, among other things, an increase in the Rent in amounts as agreed upon by the parties hereto pursuant to the agreed funding proposal terms described above and other provisions as may be necessary or appropriate;

(iv) a deed or such other agreement conveying title or beneficial interest to Landlord to any land, easements, or rights of way acquired for the purpose of constructing the Capital Improvement free and clear of any Encumbrances except those approved by Landlord, and accompanied by an ALTA survey thereof satisfactory to Landlord;

(v) if appropriate, for each advance, endorsements to any outstanding policy of title insurance covering the Leased Property or commitments therefor reasonably satisfactory in form and substance to Landlord (i) updating the same without any additional exception except those that do not materially affect the value of such land and do not interfere with the use of the Leased Property or as may be approved by Landlord, which approval shall not be unreasonably withheld, and (ii) increasing the coverage thereof by an amount equal to the cost of the Capital Improvement;

46

(vi) Upon reasonable notice from Landlord, Tenant shall provide Landlord the right to audit and obtain billing statements, invoices, certificates, endorsements, opinions, site assessments, surveys, resolutions, ratifications, lien releases and waivers and other instruments and information reasonably required by Landlord that are attributable to the Capital Improvements funded by Landlord; and

(vii) Promptly following the completion of such construction, Tenant shall deliver to Landlord “as built” drawings of the Capital Improvement so constructed, certified as accurate by the architect or engineer that supervised the work.

(e) Notwithstanding anything to the contrary contained herein, a Tenant Capital Improvement that constitutes a Long Haul Fiber Route (a “ Long Haul TCI ”) shall be treated as Tenant’s Property, and in no event shall any such Long Haul TCI (i) become part of the Leased Property, (ii) be considered a TCI ILEC Extension or a TCI CLEC Extension or (iii) be considered part of the Communication Assets or otherwise become subject to the terms of Article XXXVI. In furtherance of the foregoing, Landlord and Tenant hereby expressly agree and acknowledge that a Long Haul TCI will not become part of the Leased Property even though the Long Haul Fiber Route constituting the Long Haul TCI enters into or passes through a geographic area where Tenant or its Subsidiaries are licensed as an incumbent local exchange carrier.

10.3 Construction Requirements for All Capital Improvements . Whether or not Landlord’s review and approval is required, for all Capital Improvements:

(a) Tenant shall comply with the applicable building codes and regulations with respect to the construction of the applicable Capital Improvement and shall have procured and paid for all municipal and other governmental permits and authorizations required to be obtained with respect to such Capital Improvement, and Landlord shall join in the application for such permits or authorizations whenever such action is necessary; provided , however , that (i) any such joinder shall be at no cost or expense to Landlord; and (ii) any plans required to be filed in connection with any such application which require the approval of Landlord as hereinabove provided shall have been so approved by Landlord;

(b) All work done in connection with such construction shall be done promptly and using materials and resulting in work that is in accordance with Prudent Industry Practice and in conformity in all material respects with all Legal Requirements; and

(c) No later than February 1 ^st of each calendar year, Tenant shall present to Landlord an “Annual Construction Summary” that (i) reports on the Capital Improvements completed during the prior calendar year, (ii) reconciles the Tenant Capital Improvements and the Capital Improvements financed by Landlord with the Annual Capital Improvement Plan established for the prior calendar year, (iii) provides a pictorial representation of each Facility illustrating which portions of the Facility are Tenant’s Property and which portions are Leased Property, (iv) provides a written description containing sufficient detail to provide a clear demarcation between Tenant’s Property and the Leased Property respective to each Tenant Capital Improvement in excess of Five Hundred Thousand Dollars ($500,000), and (v) is accompanied by a report of a nationally recognized accounting firm that confirms, based upon an

47

agreed-upon procedures review, the accuracy of the Annual Construction Summary and that the Capital Improvements have not degraded the structural integrity of the Leased Property. Tenant shall select such nationally recognized accounting firm, subject to the approval of Landlord. Any fees associated with the review of the nationally recognized accounting firm shall be shared equally between Tenant and Landlord. If, as a result of the report from the nationally recognized accounting firm, Landlord determines that a Capital Improvement has impaired the structural integrity or value of the Leased Property or that a Capital Improvement has been improperly designated as Tenant’s Property, Landlord may demand and Tenant shall be obligated to remediate the problems noted by Landlord to the satisfaction of Landlord.

(d) Within thirty (30) days after the Commencement Date, Tenant and Landlord will develop and document operating procedures to govern the Annual Construction Summary described in clause (c) above, which procedures may substitute the requirement to deliver a physical report containing required information (such as the pictorial representation) with a requirement to allow Landlord to access Tenant’s engineering record systems in order to access the same or equivalent information.

ARTICLE XI

11.1 Liens . Subject to the provisions of Article XII relating to permitted contests, Tenant will not (and will not permit any of its Subsidiaries to) directly or indirectly create or allow to remain and will promptly discharge at its expense any lien, attachment, title retention agreement or claim upon the Leased Property or any Capital Improvement thereto or any attachment, levy, claim or encumbrance in respect of the Rent, excluding, however, (i) this Master Lease; (ii) [intentionally omitted]; (iii) restrictions and other Encumbrances which are consented to in writing by Landlord (such consent not to be unreasonably withheld); (iv) liens for Impositions which Tenant or its Subsidiaries are not required to pay hereunder; (v) subleases (including, but not limited to, any rights granted by Tenant or any of its Subsidiaries pursuant to a dark fiber agreement, a dim fiber agreement or a collocation agreement) permitted by Article XXII; (vi) liens for Impositions not yet delinquent or being contested in accordance with Article XII; (vii) liens of mechanics, laborers, materialmen, suppliers or vendors for sums either disputed or not yet due, provided that (1) the payment of such sums shall not be postponed under any related contract for more than sixty (60) days after the completion of the action giving rise to such lien unless being contested in accordance with Article XII; or (2) any such liens are in the process of being contested as permitted by Article XII; (viii) any liens created by Landlord; (ix) liens related to equipment leases or equipment financing for TCI Replacements which are used or useful in Tenant’s business on the TCI Replacements, provided that the payment of any sums due under such equipment leases or equipment financing shall either (1) be paid as and when due in accordance with the terms thereof, or (2) be in the process of being contested as permitted by Article XII; (x) liens granted as security for the obligations of Tenant and its Affiliates under Permitted Leasehold Mortgages and, subject to the terms of this Section 11.1, any Debt Agreement with respect to TCI ILEC Extensions and TCI CLEC Extensions; and (xi) Easements, Pole Agreements, Permits, rights-of-way, restrictions (including zoning restrictions), covenants, encroachments, protrusions and other similar charges or encumbrances, and minor title deficiencies on or with respect to any Leased Property, in each case whether now or hereafter in existence, not individually or in the aggregate materially interfering with the conduct of the business on the Leased Property, taken as a whole.

48

For the avoidance of doubt, the parties acknowledge and agree that Tenant has not granted any liens in favor of Landlord as security for its obligations hereunder (except to the extent contemplated in the final paragraph of this Section 11.1) and nothing contained herein shall be deemed or construed to prohibit (a) the issuance of a lien on the Equity Interests in Tenant (it being agreed that any foreclosure by a lien holder on such interests in Tenant shall be subject to the restriction on Change in Control set forth in Article XXII), or (b) Tenant and its Subsidiaries from pledging any of Tenant’s Property (including any Communications Licenses), any TCI ILEC Extensions and any TCI CLEC Extensions, as collateral, but such pledge shall be subject to the obligations of Tenant to transfer the Tenant’s Property, such TCI ILEC Extensions and such TCI CLEC Extensions to a Successor Tenant pursuant to Article XXXVI free and clear of any Encumbrances to the extent the same constitute Communication Assets.

Landlord and Tenant intend that this Master Lease be an indivisible true lease that affords the parties hereto the rights and remedies of landlord and tenant hereunder and does not represent a financing arrangement. This Master Lease is not an attempt by Landlord or Tenant to evade the operation of any aspect of the law applicable to any of the Leased Property. Except as otherwise required by applicable law or any accounting rules or regulations, Landlord and Tenant hereby acknowledge and agree that this Master Lease shall be treated as an operating lease for all purposes and not as a synthetic lease, financing lease or loan and that Landlord shall be entitled to all the benefits of ownership of the Leased Property, including depreciation for all federal, state and local tax purposes.

Notwithstanding (a) the form and substance of this Master Lease and (b) the intent of the parties, and the language contained herein providing that this Master Lease shall at all times be construed, interpreted and applied to create an indivisible lease of all of the Leased Property, if any court of competent jurisdiction finds that this Master Lease is a financing arrangement, this Master Lease shall be considered a secured financing agreement and Landlord’s title to the Leased Property shall constitute a perfected first priority lien in Landlord’s favor on the Leased Property to secure the payment and performance of all the obligations of Tenant hereunder (and to that end, Tenant hereby grants, assigns and transfers to the Landlord a security interest in all right, title or interest in or to any and all of the Leased Property, as security for the prompt and complete payment and performance when due of Tenant’s obligations hereunder). Tenant authorizes Landlord, at the expense of Tenant, to make any filings or take other actions as Landlord reasonably determines are necessary or advisable in order to effect fully this Master Lease or to more fully perfect or renew the rights of the Landlord, and to subordinate to the Landlord the lien of any Permitted Leasehold Mortgagee, with respect to the Leased Property (it being understood that nothing herein shall affect the rights of a Permitted Leasehold Mortgagee under Article XVII hereof). At any time and from time to time upon the request of the Landlord, and at the expense of the Tenant, Tenant shall promptly execute, acknowledge and deliver such further documents and do such other acts as the Landlord may reasonably request in order to effect fully this Master Lease or to more fully perfect or renew the rights of the Landlord with respect to the Leased Property. Upon the exercise by the Landlord of any power, right, privilege or remedy pursuant to this Master Lease which requires any consent, approval, recording, qualification or authorization of any governmental authority, Tenant will execute and deliver, or will cause the execution and delivery of, all applications, certifications, instruments and other documents and papers that Landlord may be required to obtain from Tenant for such consent, approval, recording, qualification or authorization.

49

ARTICLE XII

12.1 Permitted Contests . Tenant, upon prior Notice to Landlord, on its own or in Landlord’s name, at Tenant’s expense, may contest, in good faith and with due diligence, the amount, validity or application, in whole or in part, of any licensure or certification decision (including pursuant to any Communications Regulation), Additional Charge (other than an Additional Charge payable to Landlord in which case Section 3.3 shall apply), Legal Requirement, Insurance Requirement, lien, attachment, levy, encumbrance, charge (including charges, fees and penalties for audit disputes under Pole Agreements, Permits and Easements relating to back rent, safety violations, unauthorized attachments, and trespass) or claim; provided , however , that (i) in the case of an unpaid Additional Charge, attachment, levy, Encumbrance, charge (including charges, fees and penalties for audit disputes under Pole Agreements, Permits and Easements relating to back rent, safety violations, unauthorized attachments, and trespass) or claim, the commencement and continuation of such proceedings shall suspend the collection thereof from Landlord and from the Leased Property or any Capital Improvement thereto; (ii) neither the Leased Property or any Capital Improvement thereto, the Rent therefrom nor any part or interest in either thereof would be in any material danger of being sold, forfeited, attached or lost; (iii) in the case of a Legal Requirement, neither Landlord nor Tenant would be in any material danger of civil or criminal liability for failure to comply therewith pending the outcome of such proceedings; (iv) in the case of a Legal Requirement, Additional Charge, Encumbrance or charge, Tenant shall give such reasonable security as may be required by Landlord to insure ultimate payment of the same and to prevent any sale or forfeiture of the Leased Property or any Capital Improvement thereto or the Rent by reason of such non-payment or noncompliance; (v) in the case of an Insurance Requirement, the coverage required by Article XIII shall be maintained; (vi) Tenant shall keep Landlord reasonably informed as to the status of the proceedings; and (vii) if such contest be finally resolved against Landlord or Tenant, Tenant shall promptly pay the amount required to be paid, together with all interest and penalties accrued thereon, or comply with the applicable Legal Requirement or Insurance Requirement.

Landlord, at Tenant’s expense and request, shall reasonably cooperate with Tenant in connection with Tenant’s exercise of any contest rights under this Article XII (including, without limitation, any audit and appeal rights of Tenant and refunds sought by Tenant) and shall execute and deliver to Tenant such authorizations and other documents as may reasonably be required in any such contest, and, if reasonably requested by Tenant or if Landlord so desires, Landlord shall join as a party therein.

The provisions of this Article XII shall not be construed to permit Tenant to contest the payment of Rent or any other amount (other than Impositions or Additional Charges which Tenant may from time to time be required to impound with Landlord) payable by Tenant to Landlord hereunder.

Tenant shall indemnify, defend, protect and save Landlord harmless from and against any liability, cost or expense of any kind that may be imposed upon Landlord in connection with any such contest and any loss resulting therefrom, except in any instance where Landlord opted to join and joined as a party in the proceeding despite Tenant’s having sent written notice to Landlord of Tenant’s preference that Landlord not join in such proceeding.

ARTICLE XIII

13.1 General Insurance Requirements . During the Term, Tenant shall at all times keep the Leased Improvements that are central office locations, and all property located in or on such Leased Improvements, including Capital Improvements thereto (collectively, the “ Insured Leased Improvements ”) and Tenant’s Property, insured with the kinds and amounts of insurance described below at each location where the Insured Leased Improvements and the Tenant’s Property located therein have a combined estimated total value exceeding Five Hundred Thousand Dollars ($500,000.00) (“ Insured Location ”). The $500,000.00 combined estimated total value amount (“ Insurable Amount ”) is subject to annual review by Tenant. Tenant may increase the Insurable Amount without first obtaining Landlord’s consent so long as: (i) the increased Insurable Amount is consistent with Tenant’s practice for its retained properties, and (ii) the increased Insurable Amount would not prevent Tenant from self-insuring its insurance obligations pursuant to Section 13.9 if it chose to do so. Otherwise, Tenant must obtain Landlord’s consent, which will not be unreasonably withheld or delayed, to increase the Insurable Amount. Each element of insurance described in this Article XIII shall be maintained with respect to the Insured Leased Improvements of each Facility and Tenant’s Property and operations thereon at an Insured Location. Such insurance shall be written by companies permitted to conduct business in the applicable State. All third party liability type policies must name Landlord as an “additional insured.” All property policies shall name Landlord as “loss payee” for its interests in each Facility. Property losses shall be payable to Landlord and/or Tenant as provided in Article XIV. In addition, the policies, as appropriate, shall name as an “additional insured” and/or “loss payee” each Permitted Leasehold Mortgagee and as an “additional insured” or “loss payee” the holder of any mortgage, deed of trust or other security agreement (“ Facility Mortgagee ”) securing any indebtedness or any other Encumbrance placed on the Leased Property in accordance with the provisions of Article XXXI (“ Facility Mortgage ”) by way of a standard form of mortgagee’s loss payable endorsement. Except as otherwise set forth herein, any property insurance loss adjustment settlement shall require the written consent of Landlord, Tenant, and each Facility Mortgagee (to the extent required under the applicable Facility Mortgage Documents) unless the amount of the loss net of the applicable deductible is less than Five Million Dollars ($5,000,000) in which event no consent shall be required. Evidence of insurance shall be deposited with Landlord and, if requested, with any Facility Mortgagee(s). The insurance policies required to be carried by Tenant hereunder shall insure against all the following risks with respect to each Insured Location of a Facility:

(a) Loss or damage by fire, vandalism and malicious mischief, extended coverage perils commonly known as “All Risk,” and all physical loss perils normally included in such All Risk insurance, including, but not limited to, sprinkler leakage and windstorm in an amount not less than the insurable value on a Maximum Foreseeable Loss (as defined below in Section 13.2) basis and including a building ordinance coverage endorsement, provided that in the event the premium cost of any or all of earthquake, flood, windstorm (including named windstorm) or terrorism coverages are available only for a premium that is more than 2.5 times the average premium paid by Tenant (or prior operator of Facilities) over the preceding three years for the insurance policy contemplated by this Section 13.1(a), then Tenant shall be entitled and required to purchase the maximum insurance coverage it deems most efficient and prudent to purchase and Tenant shall not be required to spend additional funds to purchase additional coverages insuring against such risks; and provided , further , that some property coverages might be sub-limited in an amount less than the Maximum Foreseeable Loss as long as the sub-limits are commercially reasonable and prudent as deemed by Tenant;

51

(b) Loss or damage by explosion of steam boilers, pressure vessels or similar apparatus, now or hereafter installed in each Insured Leased Improvement, in such limits with respect to any one accident as may be reasonably requested by Landlord from time to time;

(c) Flood (when any of the improvements comprising the Insured Leased Improvement is located in whole or in part within a designated 100-year flood plain area) in an amount not less than the Probable Maximum Loss of a 500 year event and such other hazards and in such amounts as may be customary for comparable properties in the area;

(d) Claims for personal injury or property damage under a policy of comprehensive general public liability insurance with amounts not less than One Hundred Million Dollars ($100,000,000) each occurrence and One Hundred Million Dollars ($100,000,000) in the annual aggregate, provided that such requirements may be satisfied through the purchase of a primary general liability policy and excess liability policies;

(e) During such time as Tenant is performing any Capital Improvements to an Insured Leased Improvement, Tenant, at its sole cost and expense, shall carry, or cause to be carried (i) workers’ compensation insurance and employers’ liability insurance covering all persons employed in connection with the improvements in statutory limits, (ii) a completed operations endorsement to the commercial general liability insurance policy referred to above, (iii) builder’s risk insurance, completed value form (or its equivalent), covering all physical loss, in an amount and subject to policy conditions satisfactory to Landlord, and (iv) such other insurance, in such amounts, as Landlord deems reasonably necessary to protect Landlord’s interest in the Insured Leased Improvement from any act or omission of Tenant’s contractors or subcontractors.

13.2 Maximum Foreseeable Loss . The term “ Maximum Foreseeable Loss ” shall mean the largest monetary loss within one area that may be expected to result from a single fire with protection impaired, the control of the fire mainly dependent on physical barriers or separations and a delayed manual firefighting by public and/or private fire brigades. If Landlord reasonably believes that the Maximum Foreseeable Loss has increased at any time during the Term, it shall have the right (unless Tenant and Landlord agree otherwise) to have such Maximum Foreseeable Loss redetermined by an impartial national insurance company reasonably acceptable to both parties (the “ Impartial Appraiser ”), or, if the parties cannot in good faith agree on an Impartial Appraiser within fifteen (15) days of Landlord’s request for an Impartial Appraiser (a “ Valuation Request Notice ”), then by Experts appointed in accordance with Section 34.1 hereof. The determination of the Impartial Appraiser (or the Experts, as the case may be) shall be final and binding on the parties hereto, and Tenant shall forthwith adjust the amount of the insurance carried pursuant to this Article XIII to the amount so determined by the Impartial Appraiser (or the Experts, as the case may be), subject to the approval of the Facility Mortgagee, as applicable. Each party shall pay one-half (1/2) of the fee, if any, of the Impartial Appraiser. If Landlord pays the Impartial Appraiser, fifty percent (50%) of such costs shall be Additional Charges hereunder and if Tenant pays such Impartial Appraiser, fifty percent (50%) of such costs shall be a credit against the next Rent payment hereunder.

52

13.3 Additional Insurance . In addition to the insurance described above, Tenant shall maintain adequate workers’ compensation coverage and any other coverage required by Legal Requirements for all Persons employed by Tenant on the Leased Property in accordance with Legal Requirements.

13.4 Waiver of Subrogation . All insurance policies carried by either party covering the Leased Property or Tenant’s Property, including, without limitation, contents, fire and liability insurance, shall expressly waive any right of subrogation on the part of the insurer against the other party. Each party, respectively, shall pay any additional costs or charges for obtaining such waiver.

13.5 Policy Requirements . All of the policies of insurance referred to in this Article XIII shall be written in form reasonably satisfactory to Landlord and any Facility Mortgagee and issued by insurance companies with a minimum policyholder rating of “A-” and a financial rating of “VII” in the most recent version of Best’s Key Rating Guide, or a minimum rating of “BBB” from Standard & Poor’s or equivalent. If Tenant obtains and maintains the general liability insurance described in Section 13.1(d) above on a “claims made” basis, Tenant shall provide continuous liability coverage for claims arising during the Term. In the event such “claims made” basis policy is canceled or not renewed for any reason whatsoever (or converted to an “occurrence” basis policy), Tenant shall either obtain (a) “tail” insurance coverage converting the policies to “occurrence” basis policies providing coverage for a period of at least three (3) years beyond the expiration of the Term, or (b) an extended reporting period of at least three (3) years beyond the expiration of the Term. Notwithstanding the foregoing, it is agreed that a captive insurer may issue insurance policies to meet the requirements under Section 13.1, provided that (i) such captive insurer is fully reinsured by insurers or reinsurers with a rating of “A- VIII” or better in the most recent version of Best’s Key Rating and Tenant furnishes evidence of such reinsurance upon Landlord’s request and (ii) Tenant provides a copy of the audited financial statements of the captive insurer upon Landlord’s request. Tenant will have an actuarial study of the captive insurer performed each calendar year, which actuarial study shall be subject to Landlord’s reasonable approval. If the actuarial study recommends that the captive’s policyholder surplus be increased, then Tenant shall either provide the funding necessary to increase the captive’s policyholder surplus to the recommended level or provide alternative insurance to cover any recommended increase of the captive’s policyholder surplus. Tenant shall pay all of the premiums therefor, and deliver certificates thereof to Landlord prior to their effective date (and with respect to any renewal policy, prior to the expiration of the existing policy), and in the event of the failure of Tenant either to effect such insurance in the names herein called for or to pay the premiums therefor, or to deliver such certificates thereof to Landlord, at the times required, Landlord shall be entitled, but shall have no obligation, to effect such insurance and pay the premiums therefor, in which event the cost thereof, together with interest thereon at the Overdue Rate, shall be repayable to Landlord upon demand therefor. Tenant shall obtain, to the extent available on commercially reasonable terms, the agreement of each insurer, by endorsement on the policy or policies issued by it, or by independent instrument furnished to Landlord, that it will give to Landlord thirty (30) days’ (or ten (10) days’ in the case of non-payment of premium) Notice before the policy or policies in question shall be altered, allowed to expire or cancelled; provided however , that if such endorsement cannot be obtained, then Tenant shall be required to deliver Notice of any cancellation to Landlord promptly following Tenant having obtained knowledge of such cancellation (but in no event later than ten

53

(10) days prior to the date of cancellation). Notwithstanding any provision of this Article XIII to the contrary, Landlord acknowledges and agrees that the coverage required to be maintained by Tenant may be provided under one or more policies with various deductibles or self-insurance retentions by Tenant or its Affiliates, subject to Landlord’s approval not to be unreasonably withheld. Upon written request by Landlord, Tenant shall provide Landlord copies of the property insurance policies when issued by the insurers providing such coverage.

13.6 Increase in Limits . If, from time to time after the Commencement Date, Landlord determines in the exercise of its reasonable business judgment that the limits of the personal injury or property damage-public liability insurance then carried pursuant to Section 13.1(d) hereof are insufficient, Landlord may give Tenant Notice of acceptable limits for the insurance to be carried; provided that in no event will Tenant be required to carry insurance in an amount which exceeds the product of (i) the amounts set forth in Section 13.1(d) hereof and (ii) the CPI Increase; and subject to the foregoing limitation, within ninety (90) days after the receipt of such Notice, the insurance shall thereafter be carried with limits as prescribed by Landlord until further increase pursuant to the provisions of this Section 13.6.

13.7 Blanket Policy . Notwithstanding anything to the contrary contained in this Article XIII Tenant’s obligations to carry the insurance provided for herein may be brought within the coverage of a so-called blanket policy or policies of insurance carried and maintained by Tenant; provided that the requirements of this Article XIII (including satisfaction of the Facility Mortgagee’s requirements and the approval of the Facility Mortgagee) are otherwise satisfied, and provided further that Tenant maintains specific allocations acceptable to Landlord.

13.8 No Separate Insurance . Tenant shall not, on Tenant’s own initiative or pursuant to the request or requirement of any third party, (i) take out separate insurance concurrent in form or contributing in the event of loss with that required in this Article XIII to be furnished by, or which may reasonably be required to be furnished by, Tenant or (ii) increase the amounts of any then existing insurance by securing an additional policy or additional policies, unless all parties having an insurable interest in the subject matter of the insurance, including in all cases Landlord and all Facility Mortgagees, are included therein as additional insureds and the loss is payable under such insurance in the same manner as losses are payable under this Master Lease. Notwithstanding the foregoing, nothing herein shall prohibit Tenant from insuring against risks not required to be insured hereby, and as to such insurance, Landlord and any Facility Mortgagee need not be included therein as additional insureds, nor must the loss thereunder be payable in the same manner as losses are payable hereunder except to the extent required to avoid a default under the Facility Mortgage.

13.9 Self-Insurance . Notwithstanding anything to the contrary contained herein, Tenant may self-insure its insurance obligations under Section 13.1 subject to and in accordance with the terms of this Section 13.9.

(a) Self-insure shall mean that Tenant is itself acting as though it were the insurance company providing the insurance required under the provisions hereof and Tenant shall pay any amounts due in lieu of insurance proceeds because of self-insurance, which amounts shall be treated as insurance proceeds for all purposes under this Master Lease.

54

(b) All amounts which Tenant pays or is required to pay and all loss or damages resulting from risks for which Tenant has elected to self-insure shall be subject to the waiver of subrogation provisions of this Master Lease and shall not limit Tenant’s indemnification obligations set forth in this Master Lease.

(c) Tenant’s right to self-insure and to continue to self-insure is subject to the following conditions being met:

(i) No later than sixty (60) days prior to the date that Tenant commences to self-insure and no later than sixty (60) days prior to each anniversary thereof (each a “ Determination Date ”), Tenant shall furnish to Landlord a report reasonably acceptable to Landlord prepared by an insurance expert reasonably acceptable to Landlord which sets forth the Maximum Foreseeable Loss and the Probable Maximum Loss as of the Determination Date, together with a certificate from Tenant certifying Tenant’s compliance with the requirements set forth in this Section 13.9.

(ii) The Maximum Expected Annual Aggregate Loss does not exceed four percent (4%) of the Consolidated Adjusted EBITDA for Tenant and its Subsidiaries based on the audited Financial Statements furnished to Landlord in accordance with Section 23.1(b)(i) for the Fiscal Year immediately preceding the Determination Date. The term “ Maximum Expected Annual Aggregate Loss ” shall mean, with respect to the applicable Determination Date, the sum of (A) the Probable Maximum Loss set forth in the report delivered to Landlord in accordance with clause (c)(i) above, (B) Tenant’s combined deductibles under Tenant’s property and executive protection insurance policies and (C) the average expenses incurred by Tenant and its Subsidiaries as a result of property damage to the Leased Property, the Capital Improvements, and Tenant’s Property over the immediately preceding five (5) years which are not covered by the insurance policies maintained by Tenant in accordance with Section 13.1, which expenses shall be substantiated by Tenant to Landlord in a manner reasonably acceptable to Landlord.

(iii) The Maximum Foreseeable Loss set forth in the report delivered to Landlord in accordance with clause (c)(i) above for the applicable Determination Date does not exceed six percent (6%) of the Consolidated Adjusted EBITDA for Tenant and its Subsidiaries based on the audited Financial Statements furnished to Landlord in accordance with Section 23.1(b)(i) for the Fiscal Year immediately preceding the Determination Date.

(iv) No events shall occur that make it apparent that such Consolidated Adjusted EBITDA shall have been diminished below the required level beyond a de minimis extent.

(d) In the event Tenant fails to timely fulfill the requirements of this Section 13.9, then Tenant shall immediately lose the right to self-insure during the continuance of such failure and shall be required to provide the insurance otherwise specified in this Article XIII during the continuance of such failure.

55

(e) In the event that Tenant elects to self-insure and an event or claim occurs for which a defense and/or coverage would have been available from the insurance company, Tenant shall (i) take the defense at Tenant’s sole cost and expense of any such claim, including a defense of Landlord and such other parties as Landlord has designated as additional insureds, with counsel selected by Tenant and reasonably acceptable to Landlord and such other parties, provided Tenant has been furnished with the names of such other parties, and (ii) use its own funds to pay any claim or replace any property or otherwise provide the funding which would have been available from insurance proceeds but for such election by Tenant to self-insure.

13.10 Distribution Systems . Notwithstanding anything herein to the contrary, to the extent consistent with communications industry practice, Tenant is only required to keep those portions of the Distribution Systems that are located within one thousand (1000) feet of an Insured Leased Improvement at an Insured Location insured in accordance with the terms of this Article XIII .

ARTICLE XIV

Subject to Landlord’s option to receive liquidated damages under this Section 16.3, none of (i) the termination of this Master Lease, (ii) the repossession of the Leased Property (including any Capital Improvements to any Facility), (iii) the failure of Landlord to relet the Leased Property or any portion thereof, (iv) the reletting of all or any portion of the Leased Property, or (v) the inability of Landlord to collect or receive any rentals due upon any such reletting, shall relieve Tenant of its liabilities and obligations hereunder, all of which shall survive any such termination, repossession or reletting. Landlord and Tenant agree that Landlord shall have no obligation to mitigate Landlord’s damages under this Master Lease. If any such termination of this Master Lease occurs (whether or not Landlord terminates Tenant’s right to possession of the Leased Property), Tenant shall forthwith pay to Landlord all Rent due and payable under this Master Lease to and including the date of such termination. Thereafter:

Tenant shall forthwith pay to Landlord, at Landlord’s option, as and for liquidated and agreed current damages for the occurrence of an Event of Default, either:

(a) the sum of:

(i) the worth at the time of award of the unpaid Rent which had been earned at the time of termination to the extent not previously paid by Tenant under this Section 16.3;

(ii) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided;

(iii) the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; plus

(iv) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Master Lease or which in the ordinary course of things would be likely to result therefrom.

As used in clauses (i) and (ii) above, the “worth at the time of award” shall be computed by allowing interest at the Overdue Rate. As used in clause (iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of New York at the time of award plus one percent (1%) and reducing such amount by the portion of the unpaid Rent that Tenant proves could be reasonably avoided.

or

(b) if Landlord chooses not to terminate Tenant’s right to possession of the Leased Property (whether or not Landlord terminates the Master Lease), each installment of said Rent and other sums payable by Tenant to Landlord under this Master Lease as the same becomes due and payable, together with interest at the Overdue Rate from the date when due until paid, and Landlord may enforce, by action or otherwise, any other term or covenant of this Master Lease (and Landlord may at any time thereafter terminate Tenant’s right to possession of the Leased Property and seek damages under subparagraph (a) hereof, to the extent not already paid for by Tenant under this subparagraph (b)).

62

16.5 Waiver . If Landlord initiates judicial proceedings or if this Master Lease is terminated by Landlord pursuant to this Article XVI, Tenant waives, to the extent permitted by applicable law, (i) any right of redemption, re-entry or repossession; and (ii) the benefit of any laws now or hereafter in force exempting property from liability for rent or for debt.

16.6 Application of Funds . Any payments received by Landlord under any of the provisions of this Master Lease during the existence or continuance of any Event of Default which are made to Landlord rather than Tenant due to the existence of an Event of Default shall be applied to Tenant’s obligations in the order which Landlord may reasonably determine or as may be prescribed by the laws of the State.

(iii) After Landlord has received the notice provided for by subsection (b)(i) above, the Tenant, upon being requested to do so by Landlord, shall with reasonable promptness provide Landlord with copies of the note or other obligation secured by such Permitted Leasehold Mortgage and of any other documents pertinent to the Permitted Leasehold Mortgage as specified by the Landlord. If requested to do so by Landlord, Tenant shall thereafter also provide the Landlord from time to time with a copy of each amendment or other modification or supplement to such instruments. All recorded documents shall be accompanied by the appropriate recording stamp or other certification of the custodian of the relevant recording office as to their authenticity as true and correct copies of official records and all nonrecorded documents shall be accompanied by a certification by Tenant that such documents are true and correct copies of the originals. From time to time upon being requested to do so by Landlord, Tenant shall also notify Landlord of the date and place of recording and other pertinent recording data with respect to such instruments as have been recorded.

(c) Default Notice . Landlord, upon providing Tenant any notice of: (i) default under this Master Lease or (ii) a termination of this Master Lease, shall at the same time provide a copy of such notice to every Permitted Leasehold Mortgagee for which notice has been properly provided to Landlord pursuant to Section 17.1(b) hereof. No such notice by Landlord to Tenant shall be deemed to have been duly given unless and until a copy thereof has been sent, in the manner prescribed in Section 35.1 of this Master Lease, to every Permitted Leasehold Mortgagee for which notice has been properly provided to Landlord pursuant to Section 17.1(b) hereof. From and after such notice has been sent to a Permitted Leasehold Mortgagee, such Permitted Leasehold Mortgagee shall have the same period, after the giving of such notice, as is given Tenant after the giving of such notice to Tenant, plus in each instance, the additional

64

periods of time specified in Section 17.1(d) and Section 17.1(e) to remedy, commence remedying or cause to be remedied the defaults or acts or omissions which are specified in any such notice. Landlord shall accept such performance by or at the instigation of such Permitted Leasehold Mortgagee as if the same had been done by Tenant. Tenant authorizes each Permitted Leasehold Mortgagee (to the extent such action is authorized under the applicable Debt Agreement) to take any such action at such Permitted Leasehold Mortgagee’s option and does hereby authorize entry upon the Leased Property by the Permitted Leasehold Mortgagee for such purpose.

(d) Notice to Permitted Leasehold Mortgagee . Anything contained in this Master Lease to the contrary notwithstanding, if any default shall occur which entitles Landlord to terminate this Master Lease, Landlord shall have no right to terminate this Master Lease on account of such default unless, following the expiration of the period of time given Tenant to cure such default or the act or omission which gave rise to such default, Landlord shall notify every Permitted Leasehold Mortgagee for which notice has been properly provided to Landlord pursuant to Section 17.1(b) hereof of Landlord’s intent to so terminate at least thirty (30) days in advance of the proposed effective date of such termination if such default is capable of being cured by the payment of money, and at least ninety (90) days in advance of the proposed effective date of such termination if such default is not capable of being cured by the payment of money (“ Termination Notice ”).

(ii) pay or cause to be paid all Rent, Additional Charges, and other payments (i) then due and in arrears as specified in the Termination Notice to such Permitted Leasehold Mortgagee and (ii) which may become due during such thirty (30) or ninety (90) day (as the case may be) period (as the same may become due); and

(iii) comply or in good faith, with reasonable diligence and continuity, commence to comply with all nonmonetary requirements of this Master Lease then in default and reasonably susceptible of being complied with by such Permitted Leasehold Mortgagee, provided , however , that such Permitted Leasehold Mortgagee shall not be required during such ninety (90) day period to cure or commence to cure any default consisting of Tenant’s failure to satisfy and discharge any charge or Encumbrance against the Tenant’s interest in this Master Lease or the Leased Property, or any of Tenant’s other assets junior in priority to the lien of the mortgage or other security documents held by such Permitted Leasehold Mortgagee; and

(iv) during such thirty (30) or ninety (90) day period, the Permitted Leasehold Mortgagee shall respond, with reasonable diligence, to requests for information from Landlord as to the Permitted Leasehold Mortgagee’s (and related lenders’) intent to pay such Rent and other charges and comply with this Master Lease.

(e) Procedure on Default .

(i) If Landlord shall elect to terminate this Master Lease by reason of any Event of Default of Tenant that has occurred and is continuing, and a Permitted Leasehold Mortgagee shall have proceeded in the manner provided for by Section 17.1(d), the specified date for the termination of this Master Lease as fixed by Landlord in its Termination Notice shall be extended for a period of six (6) months; provided that such Permitted Leasehold Mortgagee shall, during such six-month period (and during the period of any continuance referred to in subsection (e)(ii) below):

(1) pay or cause to be paid the Rent, Additional Charges and other monetary obligations of Tenant under this Master Lease as the same become due, and continue its good faith efforts to perform or cause to be performed all of Tenant’s other obligations under this Master Lease, excepting (A) obligations of Tenant to satisfy or otherwise discharge any charge or Encumbrance against Tenant’s interest in this Master Lease or the Leased Property or any of Tenant’s other assets junior in priority to the lien of the mortgage or other security documents held by such Permitted Leasehold Mortgagee and (B) past nonmonetary obligations then in default and not reasonably susceptible of being cured by such Permitted Leasehold Mortgagee; and

(2) if not enjoined or stayed pursuant to a bankruptcy or insolvency proceeding or other judicial order, diligently continue to pursue acquiring or selling Tenant’s interest in this Master Lease and the Leased Property by foreclosure of the Permitted Leasehold Mortgage or other appropriate means and diligently prosecute the same to completion.

(ii) If at the end of such six (6) month period such Permitted Leasehold Mortgagee is complying with subsection (e)(i) above, this Master Lease shall not then terminate, and the time for completion by such Permitted Leasehold Mortgagee of its proceedings shall continue ( provided that for the time of such continuance, such Permitted Leasehold Mortgagee is in compliance with subsection (e)(i) above) (x) so long as such Permitted Leasehold Mortgagee is enjoined or stayed pursuant to a bankruptcy or insolvency proceeding or other judicial order and if so enjoined or stayed, thereafter for so long as such Permitted Leasehold Mortgagee proceeds to complete steps to acquire or sell Tenant’s interest in this Master Lease by foreclosure of the Permitted Leasehold Mortgage or by other appropriate means with reasonable diligence and continuity but not to exceed twelve (12) months after the Permitted Leasehold Mortgagee is no longer so enjoined or stayed from prosecuting the same and in no event longer than twenty-four (24) months from the date of Landlord’s initial notification to Permitted Leasehold Mortgagee pursuant to Section 17.1(d) hereof, and (y) if such Permitted Leasehold Mortgagee is not so enjoined or stayed, thereafter for so long as such Permitted Leasehold Mortgagee proceeds to complete steps to acquire or sell Tenant’s interests in this Master Lease by foreclosure of the Permitted Leasehold Mortgage or by other appropriate means with reasonable diligence and continuity but not to exceed twelve (12) months from the date of Landlord’s initial notification to Permitted Leasehold Mortgagee pursuant to Section 17.1(d) hereof. Nothing in this Section 17.1(e), however, shall be construed to extend this Master Lease beyond the original term thereof as extended by any options to extend the term of this Master Lease properly exercised by Tenant or a Permitted Leasehold Mortgagee in accordance with Section 1.4, nor to require a Permitted Leasehold Mortgagee

66

to continue such foreclosure proceeding after the default has been cured. If the default shall be cured pursuant to the terms and within the time periods allowed in Sections 17.1(d) and 17.1(e) and the Permitted Leasehold Mortgagee shall discontinue such foreclosure proceedings, this Master Lease shall continue in full force and effect as if Tenant had not defaulted under this Master Lease.

(iii) If a Permitted Leasehold Mortgagee is complying with Section 17.1(e)(i), upon the acquisition of Tenant’s Leasehold Estate herein by a Discretionary Transferee this Master Lease shall continue in full force and effect as if Tenant had not defaulted under this Master Lease, provided that such Discretionary Transferee cures all outstanding defaults that can be cured through the payment of money and all other defaults that are reasonably susceptible of being cured.

(iv) For the purposes of this Section 17.1, the making of a Permitted Leasehold Mortgage shall not be deemed to constitute an assignment or transfer of this Master Lease nor of the Leasehold Estate hereby created, nor shall any Permitted Leasehold Mortgagee, as such, be deemed to be an assignee or transferee of this Master Lease or of the Leasehold Estate hereby created so as to require such Permitted Leasehold Mortgagee, as such, to assume the performance of any of the terms, covenants or conditions on the part of the Tenant to be performed hereunder; but the purchaser at any sale of this Master Lease (including a Permitted Leasehold Mortgagee if it is the purchaser at foreclosure) and of the Leasehold Estate hereby created in any proceedings for the foreclosure of any Permitted Leasehold Mortgage, or the assignee or transferee of this Master Lease and of the Leasehold Estate hereby created under any instrument of assignment or transfer in lieu of the foreclosure of any Permitted Leasehold Mortgage, shall be subject to Article XXII hereof (including the requirement that such purchaser assume the performance of the terms, covenants or conditions on the part of the Tenant to be performed hereunder and meet the qualifications of Discretionary Transferee or be reasonably consented to by Landlord in accordance with Section 22.2(i) hereof).

19.1 Holding Over . If Tenant shall for any reason remain in possession of the Leased Property of a Facility after the expiration or earlier termination of the Term with respect to such Facility without the consent of Landlord (other than Tenant remaining in possession of a Facility in accordance with Section 36.3) such possession shall be as a month-to-month tenant during which time Tenant shall pay as Rent each month twice the monthly Rent applicable to the prior Lease Year for such Facility, as reasonably determined by Landlord, together with all Additional Charges and all other sums payable by Tenant pursuant to this Master Lease.

If, in connection with granting any Permitted Leasehold Mortgage or entering into a Debt Agreement, Tenant shall reasonably request (A) reasonable cooperation from Landlord, Landlord shall provide the same at no cost or expense to Landlord, it being understood and agreed that Tenant shall be required to reimburse Landlord for all such costs and expenses so incurred by Landlord, including, but not limited to, its reasonable attorneys’ fees, or (B) reasonable amendments or modifications to this Master Lease as a condition thereto, Landlord hereby agrees to execute and deliver the same so long as any such amendments or modifications do not (i) increase Landlord’s monetary obligations under this Master Lease, (ii) adversely increase Landlord’s non-monetary obligations under this Master Lease in any material respect, (iii) diminish Landlord’s rights under this Master Lease in any material respect, (iv) adversely impact the value of the Leased Property or (v) adversely impact Landlord’s (or any Affiliate of Landlord’s) tax treatment or position.

ARTICLE XXXIV

34.1 Expert Valuation Process . (a) If it becomes necessary to determine the Maximum Foreseeable Loss, and the parties are unable to agree thereon, then the same shall be determined by two Experts, one such Expert to be selected by Landlord to act on its behalf and the other such Expert to be selected by Tenant to act on its behalf. Landlord or Tenant, as applicable, shall cause its Expert to, within forty-five (45) days after the applicable Valuation Request Notice (the “ Initial Valuation Period ”), determine the Maximum Foreseeable Loss as of the relevant date (giving effect to the impact, if any, of inflation from the date of the Expert’s decision to the relevant date); provided , however , that if either party shall fail to appoint its Expert within the time permitted, or if two Experts shall have been so appointed but only one such Expert shall have made such determination within such forty-five (45) day period, then the determination of such sole Expert shall be final and binding upon the parties. For purposes of clarity, the “relevant date” with respect to any determination of the Maximum Foreseeable Loss shall be deemed to be the date on which Tenant must adjust the amount of insurance carried pursuant to Article XIII. A written report of each Expert shall be delivered and addressed to each of Landlord and Tenant. This provision for determination by an expert valuation process shall be specifically enforceable to the extent such remedy is available under applicable law, and any determination hereunder shall be final and binding upon the parties except as otherwise provided by applicable law.

89

(b) If the two Experts shall have been appointed and shall have made their determinations within the respective requisite periods set forth above and if the difference between the amounts so determined shall not exceed ten percent (10%) of the lesser of such amounts then the Maximum Foreseeable Loss shall be an amount equal to fifty percent (50%) of the sum of the amounts so determined. If the difference between the amounts so determined shall exceed ten percent (10%) of the lesser of such amounts, then such two Experts shall have ten (10) days to appoint a third Expert meeting the above requirements, but if such Experts fail to do so, then either party may request the American Arbitration Association or any successor organization thereto to appoint an Expert meeting the above requirements (such Expert, the “ Third Expert ”) within ten (10) days of such request, and both parties shall be bound by any appointment so made within such ten (10) day period. If no such Expert shall have been appointed within such ten (10) days or within the Initial Valuation Period, whichever is earlier, either Landlord or Tenant may apply to any court having jurisdiction to have such appointment made by such court. Any Expert appointed by the original Experts, by the American Arbitration Association or by such court shall be instructed to determine the Maximum Foreseeable Loss within thirty (30) days (together with the Initial Valuation Period, the “ Valuation Period ”) after appointment of such Expert.

(c) If a Third Expert is appointed in accordance with Section 34.1(b), then such Third Expert shall choose which of the determinations made by the other two (2) Experts shall be final and binding, and such chosen determination shall be final and binding upon Landlord and Tenant as the Maximum Foreseeable Loss.

(d) Landlord and Tenant shall each pay the fees and expenses of the Expert appointed by it and each shall pay one-half (1/2) of the fees and expenses of the Third Expert.

or to such other address as either party may hereafter designate. Notice shall be deemed to have been given on the date of delivery if such delivery is made on a Business Day, or if not, on the first Business Day after delivery. If delivery is refused, Notice shall be deemed to have been given on the date delivery was first attempted.

ARTICLE XXXVI

36.1 Transfer of Tenant’s Property and Operational Control of the Facilities .

(a) Upon (i) Tenant’s election or deemed election not to extend the Master Lease for any Facility by the Renewal Election Outside Date (a “ Non-Renewal Event ”), (ii) the expiration of the final Renewal Term (the “ Final Lease Expiration ”) or (iii) the delivery by Landlord of a Notice (a “ Lease Termination Notice ”) to Tenant exercising Landlord’s right to terminate this Master Lease or repossess the Leased Property in accordance with the terms of this Master Lease, Tenant shall transfer (or cause to be transferred) upon such expiration or earlier termination of the Term with respect to any Facility that is subject to such expiration or earlier termination (each an “ Affected Facility ”) or as soon thereafter as Landlord shall request, the Communication Assets to a successor lessee or operator (or lessees or operators) of such Affected Facility (collectively, the “ Successor Tenant ”) designated pursuant to Section 36.2 for consideration to be received by Tenant (or Tenant’s Subsidiaries) from the Successor Tenant in an amount equal to the Fair Market Value of the Communications Assets (the “ Communications Assets FMV ”) as either (x) negotiated and agreed in writing by Tenant and the Successor Tenant (the “ Negotiated Communications Assets FMV ”) in accordance with Section 36.2(c)(i) or (y) if (A) the Tenant and Successor Tenant have not agreed in writing on the Communications Assets FMV for an Affected Facility by the date that is ninety (90) days prior to the expiration of the Term (other than in connection with the Final Lease Expiration) or (B) a Lease Termination Notice has been delivered to Tenant and remains in effect or the Final Lease Expiration shall have occurred, then such Communications Assets FMV shall be determined, and Tenant’s transfer of the Communication Assets to a Successor Tenant in consideration for a payment in such amount shall be determined and transferred, in accordance with the provisions of Section 36.2. Notwithstanding the foregoing, in the event (i) the Credit Agreement Agent has notified Landlord that a default or event of default (beyond all applicable notice and cure periods) has occurred and is continuing under the Credit Agreement or the transfer of the Communication Assets would constitute a sale of all or substantially all of the Tenant’s assets on a consolidated basis (each a “ Credit Agreement Agent Trigger Event ”), (ii) the Successor Tenant is a Person

91

other than the Credit Agreement Agent (acting on behalf of the lenders under the Credit Agreement) or its designee and (iii) the Negotiated Communications Assets FMV is less than Credit Agreement Payoff Amount of which Landlord receives notices from Credit Agreement Agent, then Tenant and Successor Tenant shall be deemed to not have agreed on the Communications Assets FMV and the Communications Assets FMV shall be determined in accordance with Section 36.2. For the purpose of clarification, except as provided in Section 36.2(d), the Communication Assets must be transferred in whole (and not in part) to the Successor Tenant in exchange for the Communications Assets FMV.

(b) For purposes of determining the Communication Assets, Landlord and Tenant acknowledge that there may be instances where Tenant provides services to a customer at multiple locations, some of which are directly served by an Affected Facility and some of which are not directly served by an Affected Facility. In such circumstances, Landlord and Tenant have agreed not to divide the customer relationship between Tenant and the Successor Tenant. Therefore, Landlord and Tenant agree that in such circumstances, Tenant will retain the entire customer relationship unless the revenue generated by the customer relationship is predominately derived from services provided to customer locations directly served by an Affected Facility, in which case the entire customer relationship will be included as part of the Communication Assets to be sold to a Successor Tenant under this Article XXXVI.

36.2 Determination of Successor Lessee and Communications Assets FMV .

(a) The determination of the Communications Assets FMV and the transfer of the Communications Assets to a Successor Tenant in consideration for the Communications Assets FMV shall be effected by (i)  first , determining the Successor Tenant Rent in accordance with Section 1.4(b) in the case of a Non-Renewal Event or Section 41.14 in the case of a Final Lease Expiration or a termination of this Master Lease (ii)  second , identifying and designating in accordance with the terms of Section 36.2(b), a pool of qualified potential Successor Tenants (each, a “ Qualified Successor Tenant ”) prepared to lease the Affected Facility at the Successor Tenant Rent and to bid for the Communications Assets of the Affected Facility, and (iii)  third , subject to and in accordance with the terms of Section 36.2(c)(ii), determining the highest price a Qualified Successor Tenant would agree to pay for the Communications Assets of the Affected Facility and setting such highest price as the Communications Assets FMV in exchange for which Tenant shall be required to transfer such Communications Assets. Landlord will enter into a lease with such Qualified Successor Tenant on substantially the same terms and conditions of this Master Lease (except that (1) the Leased Property shall only include the Leased Property pertaining to the Affected Facility, (2) the term shall be ten (10) years, (3) the rent shall be the Successor Tenant Rent, and (4) the references to Discretionary COC Transferee shall be deleted from the Master Lease and, to the extent not duplicative, the term Discretionary Transferee shall be substituted in its place).

(b) Designating Potential Successor Tenants. Landlord will select three (3) (one of which will be Landlord or an Affiliate of Landlord) and Tenant will select four (4) (one of which will be the Credit Agreement Agent or its designee) (for a total of up to seven (7)) potential Qualified Successor Tenants prepared to lease the Affected Facility for the Successor Tenant Rent, each of whom must meet the criteria established for a Discretionary Transferee, or in the case of Credit Agreement Agent or its designee, a Discretionary COC Transferee (and

92

none of whom may be Tenant or an Affiliate of Tenant). Landlord and Tenant must designate their proposed Qualified Successor Tenants within one hundred eighty (180) days prior to the expiration of the Term or, in the case of a termination of this Master Lease, within thirty (30) days after delivery of the Lease Termination Notice. In the event that Landlord or Tenant fails to designate such party’s allotted number of potential Qualified Successor Tenants, the other party may designate additional potential Qualified Successor Tenants such that the total number of potential Qualified Successor Tenants does not exceed seven (7); provided that, in the event the total number of potential Qualified Successor Tenants is less than seven (7), the transfer process will still proceed as set forth in Section 36.2(c) below.

(c) Determining Communications Assets FMV.

(i) Tenant will have a three (3) month period to enter into a definitive agreement specifying the Negotiated Communication Assets FMV and all other terms and conditions for the sale of the Communication Assets of the Affected Facility with one of the Qualified Successor Tenants (such agreement, a “ Communications Assets Sale Agreement ”) which three (3) month period will commence immediately upon the conclusion of the steps set forth above in Section 36.2(b); provided , however , that (x) if Landlord is notified by the Credit Agreement Agent that a Credit Agreement Agent Trigger Event exists, unless the Successor Tenant is the Credit Agreement Agent (acting on behalf of the lenders under the Credit Agreement) or its designee, such Negotiated Communications Assets FMV shall be not less than the Credit Agreement Payoff Amount of which Landlord receives notice from the Credit Agreement Agent and (y) notwithstanding the foregoing, if a Lease Termination Notice has been delivered to Tenant or the Final Lease Expiration shall have occurred, Landlord and Tenant shall immediately engage a Qualified Third Party Auctioneer and the following clause (ii) shall instead be applicable (in lieu of any such three (3) month period).

(ii) If (A) Tenant does not enter into a Communications Assets Sale Agreement in accordance with the terms set forth in Section 36.2(c)(i) or (B) a Lease Termination Notice has been delivered to Tenant or the Final Lease Expiration shall have occurred, Landlord and Tenant shall engage a Qualified Third Party Auctioneer to conduct an auction for the Communication Assets among the seven (7) potential successor lessees in a manner reasonably designed to maximize the value of the Communication Assets and, subject to the terms of this Section 36.2(c)(ii), Tenant will be required to transfer the Communication Assets to the Qualified Successor Tenant submitting the highest Qualified Communications Assets Bid. Except for a bid submitted by the Credit Agreement Agent (or its designee) which may be in the form of a “credit bid” of the indebtedness and other obligations outstanding under the Credit Agreement, if the Credit Agreement Agent has notified Landlord that a Credit Agreement Agent Trigger Event exists, all bids shall provide the purchase price proposed to be paid for the Communication Assets, and at least seventy-five percent (75%) of such purchase price must consist of cash or cash equivalents (each such bid, a “ Qualified Communications Assets Bid ”). Tenant shall select the highest Qualified Communications Assets Bid for the sale of the Communications Assets within fifteen (15) days after receipt of the Qualified Communications Assets Bids (the “ Selection Period ”), provided that in the event (x) the Credit Agreement Agent has notified Landlord that a Credit Agreement

93

Agent Trigger Event exists and (y) Tenant desires to select a Qualified Communications Assets Bid as the highest bid that offers cash or cash equivalents in an amount less than the Credit Agreement Payoff Amount that has been identified by the Credit Agreement Agent in a notice to Landlord, then Tenant shall be deemed to designate the Credit Agreement Agent to make such selection. Notwithstanding the foregoing, if the Credit Agreement Agent has been designated by Tenant to select the highest Qualified Communications Assets Bid pursuant to the immediately preceding sentence and the Credit Agreement Agent fails to make such selection within the Selection Period, the Credit Agreement Agent shall be deemed to have waived its right to select the highest Qualified Communications Assets Bid and Tenant shall select the highest Qualified Communications Assets Bid within the five-day period that immediately follows the Selection Period.

(d) Notwithstanding anything in the contrary in this Article XXXVI, the transfer of the Communication Assets will be conditioned upon the approval of the applicable regulatory agencies of the transfer of the applicable Communications Licenses, Pole Agreements, Easements and Permits and any other assets to the Successor Tenant and/or the issuance of new licenses as required by applicable Communications Regulations and the relevant regulatory agencies both with respect to operating and suitability criteria, as the case may be.

36.3 Operation Transfer . (a) Upon designation of a Successor Tenant (pursuant to either Sections 36.1 or 36.2, as the case may be), Tenant shall reasonably cooperate and take all actions reasonably necessary (including providing all reasonable assistance to Successor Tenant) to effectuate the transfer of operational control of the Affected Facility to Successor Tenant in an orderly manner so as to minimize to the maximum extent possible any disruption to the continued orderly operation of the Affected Facility for its Primary Intended Use. Concurrently with the transfer of the Communications Assets to Successor Tenant, Landlord and Successor Tenant shall execute a new master lease in accordance with the terms set forth in Section 36.2(a).

(b) Notwithstanding the expiration or earlier termination of the Term and anything to the contrary herein, unless Landlord consents to the contrary, in the event the transfer of the Communication Assets and operational control of the Affected Facility by Tenant to Successor Tenant is not completed by the expiration or earlier termination of the Term (or Tenant and Landlord agree on an alternative arrangement), Landlord and Tenant hereby agree to enter into a management agreement (the “ Management Agreement ”) in a form reasonably acceptable to both parties pursuant to which Tenant shall agree to (or shall cause Tenant’s Subsidiaries to agree to) continue to (and Landlord shall permit Tenant to maintain possession of the Leased Property to the extent necessary to) operate the Affected Facility in accordance with all Legal Requirements, Communications Regulations, Communications Licenses, Permits, Easements and Pole Agreements and on such other terms which are customary in the transfer to a Successor Tenant of a facility similar to the Affected Facility for a management fee equal to 110% of the reasonable operating costs (which operating expenses may include, without limitation, an allocable share of overhead and administrative costs) and 100% of the reasonable capital expenditures incurred by Tenant to continue operating the Affected Facility in accordance with the Management Agreement (which costs shall be evidenced by reasonably detailed backup information) for a term commencing upon the expiration or earlier termination of the Term with respect to the Affected Facility and ending on the date that Tenant transfers the Communications

94

Assets and operational control for the Affected Facility to a Successor Tenant (or Tenant and Landlord agree on an alternative arrangement); it being agreed and understood that (i) Tenant shall not be obligated to pay Rent for the Affected Facility during the term of the Management Agreement, (ii) Landlord shall be responsible for all costs and expenses relating to operation and maintenance of the Affected Facility except as otherwise set forth in the Management Agreement and (iii) all profits, rents and revenues relating to the Affected Facility from and after the expiration or earlier termination of the Term with respect to the Affected Facility shall belong to Landlord (except for Landlord’s obligation to pay the management fee described above).

(c) Upon the expiration or earlier termination of the Term with respect to any Affected Facility, Tenant and Landlord (or the Successor Tenant) shall cooperate with one another for a reasonable period in order to ensure that (i) a fully operational Affected Facility is transferred to Landlord or the Successor Tenant and (ii) any necessary authorizations, and legal title to Permits, Pole Agreements, and Easements not previously transferred to Landlord have been transferred to Landlord or Successor Tenant; it being agreed that Tenant shall enter into a Transition Services Agreement for a reasonable term and otherwise consistent with the terms described in the attached Exhibit D promptly following Landlord’s (or Successor Tenant’s) request in connection therewith. Upon expiration or earlier termination of the Term and following Landlord’s request, Tenant shall promptly deliver copies of all of Tenant’s books and records relating to the Easements, Permits and Pole Agreements for the Affected Facility.

36.4 Carrier of Last Resort . Each of Landlord and Tenant hereby acknowledge and agree that in no event shall any of Tenant’s “carrier of last resort obligations” under any Legal Requirements become the obligations of Landlord with respect to any Facility, and that such obligations shall remain the obligations solely of Tenant, in the event (i) the Term expires and there are no remaining Renewal Terms under Section 1.4, (ii) the Term expires as to such Facility due to Tenant’s election not to extend the Term for any Renewal Term under Section 1.4 with respect to such Facility, or (iii) the Master Lease is terminated as to such Facility in accordance with the terms hereof.

ARTICLE XXXVII

37.1 Attorneys’ Fees . If Landlord or Tenant brings an action or other proceeding against the other to enforce or interpret any of the terms, covenants or conditions hereof or any instrument executed pursuant to this Master Lease, or by reason of any breach or default hereunder or thereunder, the party prevailing in any such action or proceeding and any appeal thereupon shall be paid all of its costs and reasonable outside attorneys’ fees incurred therein. In addition to the foregoing and other provisions of this Master Lease that specifically require Tenant to reimburse, pay or indemnify against Landlord’s attorneys’ fees, Tenant shall pay, as Additional Charges, all of Landlord’s reasonable outside attorneys’ fees incurred in connection with the enforcement of this Master Lease (except to the extent provided above), including reasonable attorneys’ fees incurred in connection with the review, negotiation or documentation of any subletting, assignment, or management arrangement or any consent requested in connection therewith, and the collection of past due Rent.

Landlord warrants that it has not had any contact or dealings with any Person or real estate broker which would give rise to the payment of any fee or brokerage commission in connection with this Master Lease, and Landlord shall indemnify, protect, hold harmless and defend Tenant from and against any liability with respect to any fee or brokerage commission arising out of any act or omission of Landlord.

39.1 Anti-Terrorism Representations .

Tenant hereby represents and warrants to Landlord that no funds tendered to Landlord by Tenant under the terms of this Master Lease are or will be directly or indirectly derived from activities that may contravene U.S. federal, state or international laws and regulations, including anti-money laundering laws. If the foregoing representations are untrue at any time during the Term and Landlord suffers actual damages as a result thereof, an Event of Default will be deemed to have occurred, without the necessity of notice to Tenant.

Tenant will not during the Term of this Master Lease knowingly engage in any transactions or dealings, or knowingly be otherwise associated with, any Prohibited Persons in connection with the use or occupancy of the Leased Property. A breach of the representations contained in this Section 39.1 by Tenant as a result of which Landlord suffers actual damages shall constitute a material breach of this Master Lease and shall entitle Landlord to any and all remedies available hereunder, or at law or in equity.

ARTICLE XL

40.1 REIT Protection . (a) The parties hereto intend that Rent and other amounts paid by Tenant hereunder will qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or any similar or successor provision thereto and this Agreement shall be interpreted consistent with this intent.

(b) Anything contained in this Master Lease to the contrary notwithstanding, Tenant shall not without Landlord’s advance written consent (which consent shall not be

96

unreasonably withheld) (i) sublet, assign or enter into a management arrangement for the Leased Property on any basis such that the rental or other amounts to be paid by the subtenant, assignee or manager thereunder would be based, in whole or in part, on either (x) the income or profits derived by the business activities of the subtenant, assignee or manager or (y) any other formula such that any portion of any amount received by Landlord would fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or any similar or successor provision thereto; (ii) sublet, assign or enter into a management arrangement for the Leased Property to any Person (other than a “taxable REIT subsidiary” (within the meaning of Section 856(l) of the Code) of Landlord) in which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Code); or (iii) sublet, assign or enter into a management arrangement for the Leased Property in any other manner which could cause any portion of the amounts received by Landlord pursuant to this Master Lease or any sublease to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or any similar or successor provision thereto, or which could cause any other income of Landlord to fail to qualify as income described in Section 856(c)(2) of the Code. Anything contained in this Master Lease to the contrary notwithstanding, for so long as Tenant owns shares of Landlord, Tenant shall not without Landlord’s advance written consent (which consent shall not be unreasonably withheld) sublet, assign or enter into a management arrangement for the Leased Property to any Person in which Tenant owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Code). The requirements of this Section 40.1(b) shall likewise apply to any further subleasing by any subtenant.

(d) Anything contained in this Master Lease to the contrary notwithstanding, upon request of Landlord, Tenant shall cooperate with Landlord in good faith and at no cost or expense to Tenant, and provide such documentation and/or information as may be in Tenant’s possession or under Tenant’s control and otherwise readily available to Tenant as shall be reasonably requested by Landlord in connection with verification of Landlord’s “real estate investment trust” (within the meaning of Section 856(a) of the Code) compliance requirements. Anything contained in this Master Lease to the contrary notwithstanding, Tenant shall take such reasonable action as may be requested by Landlord from time to time in order to ensure compliance with the Internal Revenue Service requirement that Rent allocable for purposes of Section 856 of the Code to personal property, if any, at the beginning and end of a calendar year does not exceed fifteen percent (15%) of the total Rent due hereunder as long as such compliance does not (i) increase Tenant’s monetary obligations under this Master Lease or (ii) materially and adversely increase Tenant’s nonmonetary obligations under this Master Lease or (iii) materially diminish Tenant’s rights under this Master Lease.

41.14 Appraiser . (a) If it becomes necessary to determine the Renewal Rent and/or the Successor Tenant Rent pursuant to Section 1.4(b) or Section 36.2(a), and the parties are unable to agree thereon, the same shall be determined by two independent appraisal firms, in which one or more of the members, officers or principals of such firm are members of the American Society of Appraisers and such member has a minimum of 10 years’ experience in appraising facilities similar in scope and use as the Leased Property (each, an “ Appraiser ” and collectively, the “ Appraisers ”), one such Appraiser to be selected by Landlord to act on its behalf and the other such Appraiser to be selected by Tenant to act on its behalf. Landlord or Tenant, as applicable, shall cause its Appraiser to, within ninety (90) days after the Appraisal Commencement Date or Tenant’s receipt of the Lease Termination Notice or within ten (10) months prior to the Final Lease Expiration (the “ Initial Appraisal Period ”), as applicable, determine the Renewal Rent or the Successor Tenant Rent, as applicable, as of the relevant date (giving effect to the impact, if any, of inflation from the date of the Appraiser’s decision to the relevant date); provided , however , that if either party shall fail to appoint its Appraiser within the time permitted, or if two Appraisers shall have been so appointed but only one such Appraiser shall have made such determination within such ninety (90) day period, then the determination of such sole Appraiser shall be final and binding upon the parties. For purposes of clarity, the “relevant date” with respect to any determination of the Renewal Rent or the Successor Tenant Rent, as applicable, shall be deemed to be the date on which such applicable Renewal Term or lease term is to commence. A written report of each Appraiser shall be delivered and addressed to each of Landlord and Tenant; it being agreed and understood that the report delivered in connection with the appraisal process initiated under Section 1.4(b) shall include the Renewal Rent and/or Successor Tenant Rent, as applicable, for each of the Facilities. This provision for determination by appraisal shall be specifically enforceable to the extent such remedy is available under applicable law, and any determination hereunder shall be final and binding upon the parties except as otherwise provided by applicable law.

(b) If the two Appraisers shall have been appointed by Landlord and Tenant, then such two Appraisers shall agree on a third Appraiser (the “ Third Appraiser ”) that meets the above requirements no later than thirty (30) days after the Appraisal Commencement Date or

100

Tenant’s receipt of the Lease Termination Notice or twelve (12) months prior to the Final Expiration Date, as applicable, which Third Appraiser shall perform the services set forth in Section 41.14(c) to the extent such services are so required. If the two Appraisers shall have been appointed and shall have made their determinations within the respective requisite periods set forth above and if the difference between the amounts so determined shall not exceed ten percent (10%) of the lesser of such amounts, then the Renewal Rent or the Successor Tenant Rent, as applicable, shall be an amount equal to fifty percent (50%) of the sum of the amounts so determined. If the difference between the amounts so determined shall exceed ten percent (10%) of the lesser of such amounts, then the Third Appraiser shall perform the services set forth in Section 41.14(c) below. If the two Appraisers are unable to agree on the selection of the Third Appraiser by the last day of the Initial Appraisal Period, then either party may request the American Arbitration Association or any successor organization thereto to appoint the Third Appraiser meeting the above requirements within twenty (20) days of such request, and both parties shall be bound by any appointment so made within such twenty (20) day period. If no such Appraiser shall have been appointed within such twenty (20) day period or within the Initial Appraisal Period, whichever is earlier, either Landlord or Tenant may apply to any court having jurisdiction to have such appointment made by such court. Any Appraiser appointed by the original Appraisers, by the American Arbitration Association or by such court shall be instructed to determine the Renewal Rent or Successor Tenant Rent, as applicable, within sixty (60) days after the Initial Appraisal Period.

(c) If a Third Appraiser is appointed in accordance with Section 41.14(b), then such Third Appraiser shall choose (without any modifications) which of the determinations made by the other two (2) Appraisers shall be final and binding, and such chosen determination shall be final and binding upon Landlord and Tenant as the Renewal Rent or the Successor Tenant Rent, as applicable.

(d) Landlord and Tenant shall each pay the fees and expenses of the Appraiser appointed by it and each shall pay one-half (1/2) of the fees and expenses of the Third Appraiser.

FORM OF SUBORDINATION, NONDISTURBANCE

AND ATTORNMENT AGREEMENT

This SUBORDINATION, NON-DISTURBANCE, AND ATTORNMENT AGREEMENT (the “ Agreement ”) is dated as of                     , and is by and among [LENDER], a [ ] [ ] (together with its successors and assigns, “ Lender ” ¹ ), Communications Sales & Leasing, Inc., a Delaware corporation, and the entities set forth on Schedule I attached hereto (collectively, “ Landlord ”), and Windstream Holdings, Inc., a Delaware corporation (“ Tenant ”).

WHEREAS, by a Master Lease (as amended, modified or supplemented, the “ Lease ”) dated as of [                    ], between Landlord (or Landlord’s predecessor in title) and Tenant, Landlord leased the Leased Property to Tenant, as said Leased Property is more particularly described in the Lease (such Leased Property hereinafter referred to as the “ Premises ”);

WHEREAS, Lender has made or intends to make a loan to Landlord (the “ Loan ”), which Loan shall be evidenced by one or more promissory notes (as the same may be amended, modified, restated, severed, consolidated, renewed, replaced, or supplemented from time to time, the “ Promissory Note ”) and secured by, among other things, that certain Mortgage or Deed of Trust, Assignment of Leases and Rents and Security Agreement (as the same may be amended, restated, replaced, severed, split, supplemented or otherwise modified from time to time, the “ Mortgage ”) encumbering the real property located in                     more particularly described on Exhibit A annexed hereto and made a part hereof (the “ Property ”); ²

WHEREAS, Tenant acknowledges that Lender will rely on this Agreement in making the Loan to Landlord;

WHEREAS, Lender and Tenant desire to evidence their understanding with respect to the Mortgage and the Lease as hereinafter provided; and

WHEREAS, pursuant to Section 31.1 of the Lease, Tenant has agreed to deliver this Agreement and will subordinate the Lease to the Mortgage and to the lien thereof and, in consideration of Tenant’s delivery of this Agreement, Lender has agreed not to disturb Tenant’s possessory rights in the Premises under the Lease on the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the mutual agreements hereinafter set forth, the parties hereto hereby agree as follows:

C-1

1. Tenant covenants, stipulates and agrees that the Lease and all of Tenant’s right, title and interest in and to the Property thereunder is hereby, and shall at all times continue to be, subordinated and made secondary and inferior in each and every respect to the Mortgage and the lien thereof, to all of the terms, conditions and provisions thereof and to any and all advances made or to be made thereunder, so that at all times the Mortgage shall be and remain a lien on the Property prior to and superior to the Lease for all purposes, subject to the provisions set forth herein. Subordination is to have the same force and effect as if the Mortgage and such renewals, modifications, consolidations, replacements and extensions had been executed, acknowledged, delivered and recorded prior to the Lease, any amendments or modifications thereof and any notice thereof.

2. Lender agrees that if Lender exercises any of its rights under the Mortgage, including entry or foreclosure of the Mortgage or exercise of a power of sale under the Mortgage, Lender, or any person who acquires any portion of the Property in a foreclosure or similar proceeding or in a transfer in lieu of any such foreclosure, (a) will not terminate or disturb Tenant’s right to use, occupy and possess the Premises, nor any of Tenant’s rights, privileges and options under the terms of the Lease, so long as Tenant is not in default beyond any applicable grace period under any term, covenant or condition of the Lease and (b) will be bound by the provisions of Article XVII of the Lease for the benefit of each Permitted Leasehold Mortgagee. In addition, Lender or any person prosecuting such rights and remedies agrees that so long as the Lease has not been terminated on account of Tenant’s default that has continued beyond applicable notice and cure periods, Lender or such other person, as the case may be, shall not name or join Tenant as a defendant in any exercise of Lender’s or such person’s rights and remedies arising upon a default under the Mortgage unless applicable law requires Tenant to be made a party thereto as a condition to proceeding against Landlord. In the latter case, Lender or any person prosecuting such rights and remedies may join Tenant as a defendant in such action only for such purpose and not to terminate the Lease or otherwise adversely affect Tenant’s rights under the Lease or this Agreement in such action.

3. If, at any time Lender (or any person, or such person’s successors or assigns, who acquires the interest of Landlord under the Lease through foreclosure of the Mortgage or otherwise) shall succeed to the rights of Landlord under the Lease as a result of a default or event of default under the Mortgage, Tenant shall attorn to and recognize such person so succeeding to the rights of Landlord under the Lease (herein sometimes called “ Successor Landlord ”) as Tenant’s landlord under the Lease, said attornment to be effective and self-operative without the execution of any further instruments.

4. Landlord authorizes and directs Tenant to honor any written demand or notice from Lender instructing Tenant to pay rent or other sums to Lender rather than Landlord (a “ Payment Demand ”), regardless of any other or contrary notice or instruction which Tenant may receive from Landlord before or after Tenant’s receipt of such Payment Demand. Tenant may rely upon any notice, instruction, Payment Demand, certificate, consent or other document from, and signed by, Lender and shall have no duty to Landlord to investigate the same or the circumstances under which the same was given. Any payment made by Tenant to Lender or in response to a Payment Demand shall be deemed proper payment by Tenant of such sum pursuant to the Lease.

C-2

5. If Lender shall become the owner of the Property or the Property shall be sold by reason of foreclosure or other proceedings brought to enforce the Mortgage or if the Property shall be transferred by deed in lieu of foreclosure, Lender or any Successor Landlord shall not be:

(a) liable for any act or omission of any prior landlord (including Landlord) or bound by any obligation to make any payment to Tenant which was required to be made prior to the time Lender succeeded to any prior landlord (including Landlord) provided however, that if a prior landlord (including Landlord) agrees to fund a Capital Improvement under the terms of the Lease and landlord then defaults on the obligation to fund such Capital Improvement, in no event shall such Capital Improvement (other than a TCI Replacement) be deemed to be part of the Leased Property unless Lender cures the default by providing the unfunded amount to Tenant or Tenant exercises its offset right under Section 3.4 of the Master Lease.

(b) obligated to cure any defaults of any prior landlord (including Landlord) which occurred, or to make any payment to Tenant which was required to be paid by any prior landlord (including Landlord), prior to the time that Lender or any Successor Landlord succeeded to the interest of such landlord under the Lease; or

(c) obligated to perform any construction obligations of any prior landlord (including Landlord) under the Lease or liable for any defects (latent, patent or otherwise) in the design, workmanship, materials, construction or otherwise with respect to improvements and buildings constructed on the Property; or

(d) subject to any offsets, defenses or counterclaims which Tenant may be entitled to assert against any prior landlord (including Landlord); or

(e) bound by any payment of rent or additional rent by Tenant to any prior landlord (including Landlord) for more than one month in advance; or

(f) bound by any amendment, modification, termination or surrender of the Lease made without the written consent of Lender.

Notwithstanding the foregoing, Tenant reserves its right to any and all claims or causes of action (i) against Landlord for prior losses or damages and (ii) against the Successor Landlord for all losses or damages arising from and after the date that such Successor Landlord takes title to the Property.

6. Tenant hereby represents, warrants, covenants and agrees to and with Lender:

(a) to deliver to Lender, by certified mail, return receipt requested, a duplicate of each notice of default delivered by Tenant to Landlord at the same time as such notice is given to Landlord and no such notice of default shall be deemed given by Tenant under the Lease unless and until a copy of such notice shall have been so delivered to Lender. Lender shall have the right (but shall not be obligated) to cure such default. Tenant shall accept performance by Lender or its designee of any term, covenant, condition or

C-3

agreement to be performed by Landlord under the Lease with the same force and effect as though performed by Landlord. Tenant further agrees to afford Lender or the designee a period of thirty (30) days beyond any period afforded to Landlord or its designee for the curing of such default during which period Lender or its designee may elect (but shall not be obligated) to seek to cure such default, or, if such default cannot be cured within that time, then such additional time as may be reasonably necessary to cure such default (including but not limited to commencement of foreclosure proceedings) which in no event shall exceed one hundred eighty days (180) days following the expiration of such 30-day period during which period Lender or its designee may elect (but shall not be obligated) to seek to cure such default, prior to taking any action to terminate the Lease. If the Lease shall terminate for any reason, upon Lender’s written request given within thirty (30) days after such termination, Tenant, within fifteen (15) days after such request, shall execute and deliver to Lender (or its designee to the extent constituting a permitted successor landlord under the Lease) a new lease of the Premises for the remainder of the term of the Lease and upon all of the same terms, covenants and conditions of the Lease;

(b) that Tenant is the sole owner of the leasehold estate created by the Lease; and

(c) to promptly certify in writing to Lender, in connection with any proposed assignment of the Mortgage, whether or not any default on the part of Landlord then exists under the Lease and to deliver to Lender any tenant estoppel certificates required under the Lease.

7. Tenant acknowledges that the interest of Landlord under the Lease is assigned to Lender solely as security for the Promissory Note ³ , and Lender shall have no duty, liability or obligation under the Lease or any extension or renewal thereof, unless Lender shall specifically undertake such liability in writing or Lender becomes and then only with respect to periods in which Lender becomes, the fee owner of the Property.

8. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. ⁴

9. This Agreement and each and every covenant, agreement and other provisions hereof shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns (including, without limitation, any successor holder of the Promissory Note ⁵ ) and may be amended, supplemented, waived or modified only by an instrument in writing executed by the party against which enforcement of the termination, amendment, supplement, waiver or modification is sought. Each Permitted Leasehold Mortgagee (as defined in the Lease) (for so long as such Permitted Leasehold Mortgagee (as

C-4

defined in the Lease) holds a Permitted Leasehold Mortgage (as defined in the Lease)) is an intended third party beneficiary of Section 2(b) entitled to enforce the same as if a party to this Agreement.

10. All notices to be given under this Agreement shall be in writing and shall be deemed served upon receipt by the addressee if served personally or, if mailed, upon the first to occur of receipt or the refusal of delivery as shown on a return receipt, after deposit in the United States Postal Service certified mail, postage prepaid, addressed to the address of Landlord, Tenant or Lender appearing below. Such addresses may be changed by notice given in the same manner. If any party consists of multiple individuals or entities, then notice to any one of same shall be deemed notice to such party.

11. If this Agreement conflicts with the Lease, then this Agreement shall govern as between the parties and any Successor Landlord, including upon any attornment pursuant to this Agreement. This Agreement supersedes, and constitutes full compliance with, any provisions in the Lease that provide for subordination of the Lease to, or for delivery of nondisturbance agreements by the holder of, the Mortgage.

C-5

12. In the event Lender shall acquire Landlord’s interest in the Premises, Tenant shall look only to the estate and interest, if any, of Lender in the Property for the satisfaction of Tenant’s remedies for the collection of a judgment (or other judicial process) requiring the payment of money in the event of any default by Lender as a Successor Landlord under the Lease or under this Agreement, and no other property or assets of Lender shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to the Lease, the relationship of the landlord and tenant under the Lease or Tenant’s use or occupancy of the Premises or any claim arising under this Agreement.

13. If any provision of this Agreement is held to be invalid or unenforceable by a court of competent jurisdiction, such provision shall be deemed modified to the extent necessary to be enforceable, or if such modification is not practicable, such provision shall be deemed deleted from this Agreement, and the other provisions of this Agreement shall remain in full force and effect, and shall be liberally construed in favor of Lender.

14. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument.

EXHIBIT E

FAIR MARKET RENTAL CALCULATION

Landlord or Tenant, as applicable, will identify the Facilities from Exhibit A of this Master Lease that will be subject to appraisal, each such Facility being referred to herein as an “Appraised Facility”. This exhibit sets forth the framework that shall be utilized by the Appraiser(s) in determining the Fair Market Rental for each Appraised Facility.

Definitions, for purposes of this exhibit:

Fair Market Rental - The rental price that a willing renter and a willing landlord, with neither being required to act, and both having reasonable knowledge of the relevant facts.

Calculation of Fair Market Rental shall be based on the following inputs determined by appraiser:

Fair Market Rental Formula

Fair Market Rental = PMT(rate, nper, pv, [fv], [type])

rate = Fair Lease Rate

nper = Renewal Term

pv = Fair Market Value – Residual Value

fv = 0

type = 1 (lease payment due at beginning of period)

Fair Market Value - Shall be consistent with the meaning in IRS Regulation Section 20.2031-1(b) and will reflect the premise of in-continued-use. Fair market value is defined as the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or to sell and both having reasonable knowledge of relevant facts.

Residual Value – The uninflated future value of the Appraised Facility as of the expiration date of the Renewal Term, but in any case shall be based on IRS guidelines and methods consistent with that of lease transactions.

Fair Lease Rate – The rate of return used in the determination of the Fair Market Rental. The Fair Lease Rate shall be supported in Appraiser’s report by market comparable rates of return which may include analysis of a variety of factors including the Landlord’s weighed average cost of capital, the risk free rate of return, financing terms, asset/equity returns, and a market based risk premium.

All other capitalized terms shall have the meaning set forth in the Master Lease Agreement, unless otherwise defined herein.

F-1

Appraisal Process and Instructions:

(a) In determining the Fair Market Rental for purposes of establishing Renewal Rent, and/or determining Successor Tenant Rent, the appraisal methods and process shall be consistent with the valuation analysis performed for the Initial Term (the “Initial Term Appraisal”), except that a valuation analysis will be performed separately for each Appraised Facility and will not assume that any other Facilities will be part of the Leased Property comprising the Appraised Facility In addition to providing a recommendation for the Fair Market Rental for each Appraised Facility, the Appraiser will also provide recommendations for each of the following values for each Appraised Facility: (i) Fair Market Value, as of the inception date of the Renewal Term, (ii) Residual Value, (iii) remaining economic life as of the inception date of the Renewal Term, and (iv) Fair Lease Rate. In determining the Fair Market Rental and providing the recommendations under clauses (i) through (iv) in the immediately preceding sentence, Landlord shall be deemed to be the sole owner of the Easements, Permits and Pole Agreements without any deduction in value as a result of Tenant holding legal title to any such Easement, Permits and Pole Agreements subject to Tenant’s obligation to convey legal title to Landlord in accordance with Section 9.2(f) of the Master Lease.

(b) Landlord and Tenant agree to promptly provide all information associated with each Appraised Facility that is reasonably requested by Appraiser to facilitate the Appraiser review and determination of Fair Market Rental. Tenant and Landlord shall be prepared to provide any fixed asset data, network specifications, construction documents, capital investment records, historical and projected financial results, business plans, operational performance records, customer and market share data, and other information that may be reasonably requested by Appraiser for each Appraised Facility.

(c) In determining the Fair Market Value, Residual Value, remaining economic life, and Fair Lease Rate of each Appraised Facility as of the inception date of the Renewal Term, the Appraiser will follow generally accepted appraisal procedures including but not limited to the following:

F-2

To the extent the Appraiser determines Fair Market Rental to be a single amount, such amount will be considered the appraiser’s determination of Renewal Rent, or Successor Tenant Rent, as applicable. To the extent the Appraiser provides a range of amounts which represent his/her determination of Fair Market Rental, then the Renewal Rent, or Successor Tenant Rent, as applicable, shall be an amount equal to fifty percent (50%) of the sum of highest and lowest determinations of Fair Market Rental by such Appraiser.

Exhibit 10.3

TRANSITION SERVICES AGREEMENT

THIS TRANSITION SERVICES AGREEMENT (this “ Agreement ”), dated April 24, 2015, is entered into by and between Windstream Services, LLC, a Delaware limited liability company (“ WIN ”), and CSL National, LP, a Delaware limited partnership (“ CSL ”), on behalf of itself and its Affiliates, including Talk America Services, LLC (“ TAS ”). WIN and CSL are each sometimes referred to herein as a “ Party ” and, collectively, as the “ Parties ”.

WHEREAS , CSL and WIN have entered into that certain Separation and Distribution Agreement, dated March 26, 2015 (the “ Distribution Agreement ”; capitalized terms used but not defined herein shall have the meanings ascribed thereto in the Distribution Agreement), which provides, among other things, that WIN and CSL shall enter into a Transition Services Agreement in connection with the transactions contemplated by the Distribution Agreement;

WHEREAS , WIN and its Affiliates currently provide and provided as of the date of the Distribution Agreement certain services in support of the CSL Business; and

WHEREAS , to facilitate the transition of the CSL Business to CSL, the Parties desire that, for a limited transition period, WIN and its Affiliates provide certain services to CSL and its Affiliates on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, agree as follows:

1. Description of Services .

(a) Services . Subject to the terms and provisions of this Agreement and solely for the purpose of facilitating the transition of the CSL Business to CSL, WIN shall (or shall cause its Affiliates to) provide to CSL the services set forth on Exhibit 1 hereto (as such Exhibit 1 may be amended by the mutual agreement of the Parties in writing from time to time, the “ Services Attachment ”) (the “ Services ”).

(b) Purchase of Additional or Modified Services . From time to time, CSL may request WIN to provide additional or modified Services that are not described in Exhibit 1 , but are of a similar scope or nature as those used by WIN relating to the CSL Business prior to the Distribution Date. WIN will use commercially reasonable efforts to accommodate any reasonable requests by CSL to provide such additional or modified Services. In order to initiate a request for additional or modified Services, CSL shall submit a request in writing to WIN specifying the nature of the additional or modified Services and requesting a cost estimate (based on the general parameters set forth in this Agreement) and time frame for completion. WIN shall respond within ten (10) business days to such written request; provided that, subject to the second sentence of Section 1.3, such ten (10) business day period shall be subject to a reasonable extension if, due to the volume, frequency or type of requests submitted by CSL, WIN’s preparation of responses to such requests is materially interfering with, or is likely to materially interfere with, WIN’s normal business activities. If WIN can accommodate CSL’s request to provide such additional or modified Services, and if CSL accepts the terms and conditions set

1

forth in WIN’s response to such request, then such additional or modified Services shall be provided hereunder and according to the terms agreed to by the Parties in a written amendment to this Agreement, which shall be consistent to the greatest extent practicable with the terms of this Agreement.

(c) Ancillary Services . Any functions, responsibilities, activities or tasks that are not specifically described in this Agreement or the Exhibit hereto, but are reasonably required for the proper performance and delivery of the Services (including any additional or modified Services), and are a necessary or inherent part of such Services, as performed by WIN, in the ordinary course of business, shall be deemed to be implied by and included within the scope of such Services, subject to any limitations set forth in this Agreement or the Exhibit hereto, to the same extent and in the same manner as if specifically described in this Agreement.

(d) Modifications . Unless otherwise provided for in this Agreement, if CSL makes any change in the processes, procedures, practices, networks, equipment, configurations, or systems pertaining to the CSL Business, and such change has a materially adverse impact on WIN’s ability to provide any of the Services, then WIN shall be excused from performance of any such affected Service until CSL mitigates the material adverse impact of such change or the Parties enter into an agreement to purchase additional or modified services that may be necessitated by such changes, and CSL shall be responsible for all direct expenses incurred by WIN in connection with the cessation and, if applicable, the resumption of the affected Services.

(e) Transition Plan . The Parties shall agree on a written transition plan after the execution of this Agreement (the “ Transition Plan ”) which shall include: (i) a plan and timetable for the migration of CSL away from the Services; (ii) assistance in relation to migration (including the migration of data and the “Carve-Out Assistance” listed in the Services Attachment); (iii) information in relation to the operation of the relevant IT systems and the interface between such IT systems for the purpose of implementing the migration referred to in this Section (including the applicable Services listed in the Services Attachment); (iv) respective responsibilities of the Parties in carrying out the migration; and (v) safeguards to ensure minimal disruption to both Parties’ ongoing businesses during the migration. Each Party shall implement and comply with its obligations under the Transition Plan. Except as may otherwise be expressly provided in the Transition Plan or Schedule of Services, as applicable, CSL shall bear all costs associated with the migration by CSL away from the Services provided by WIN.

(f) Representatives .

(i) Transition Representatives . Each Party will designate an individual who shall be the primary interface for the purposes of coordinating the Services provided hereunder (the “ Transition Representative ”). Such individual shall (A) coordinate with the other Party and their Service Representatives (as defined below) to provide the relevant contacts in that Party’s applicable departments for the purposes of implementing and performing the Services, and (B) evaluate in consultation with the other Party’s Transition Representative when a particular Service may be terminated. The Transition Representative shall perform the duties required hereby in a professional and timely manner. Each Party may change its Transition Representative by giving written notice to the other in accordance with the notice provisions of this Agreement.

2

(ii) Role of the Service Representative . Each Party shall provide up to two (2) individuals (each, a “ Service Representative ”) who are familiar with that Party’s business and who will be that Party’s primary points of contact in dealing with the other Party’s Service Representatives under this Agreement and who will have the authority and power to make decisions with respect to actions to be taken by such Party with respect to the provision of Services under this Agreement. Each Party may change its Service Representative(s) by giving written notice to the other in accordance with the notice provisions of this Agreement.

(iii) Obligations of the Service Representatives . Each Party shall, or shall ensure that their Service Representative, as applicable, respond within a commercially reasonable time to any reasonable requests by the other Party or its Service Representative for such Party’s Service Representative to provide directions, instructions, approvals, authorizations, decisions or other information reasonably necessary for WIN to perform any Services; provided , however , any request contemplated in Section 1(b) of this Agreement shall be delivered by and to, and accepted or rejected by, the Transition Representatives.

(iv) Meetings of the Transition and Service Representatives . The Transition Representatives and the Service Representatives shall meet on a monthly basis (which meeting may be held telephonically) during the Term. The purpose of such meetings shall be to discuss the Services and each Party’s obligations under this Agreement, including operational details, transitional matters, dispute resolution and any other issues related to this Agreement. Such meetings will take place at mutually agreed locations (including by teleconference) and may include a reasonable number of additional representatives from either Party.

(g) Standard of the Provision of Services . WIN shall provide the Services in a manner and at a level as more particularly described in Section 8 of this Agreement. WIN shall provide Services in accordance in all material respects with all applicable Laws.

2. Term .

(a) The term of this Agreement shall commence on the date hereof and, unless terminated earlier in accordance with Section 12 , expire on the latest end date specified in Exhibit 1 (the “ Term ”). Thereafter, if CSL desires and WIN agrees to continue to perform any of the Services after the Term has expired, the parties shall negotiate in good faith to determine an amount that compensates WIN for all of its costs for such performance. However, should WIN fail to complete performance of any billing and/or collection Service(s), including the logical billing database separation, within the Term identified in Exhibit 1 for such Service(s), and such failure does not result from the actions or inactions of CSL or a force majeure event (as defined in Section 16 herein), the Term for such incomplete Service(s) shall be extended to accommodate complete performance without additional charge to CSL. The Services so performed by WIN after the expiration of the Term shall continue to constitute Services under this Agreement and be subject in all respects to the provisions of this Agreement for the duration of the agreed-upon extension period.

(b) WIN shall (or shall cause its Affiliates to) provide each Service for the period commencing on the date hereof and ending on the earlier to occur of (i) the expiration of the Term, (ii) the Parties mutually agree in writing that such Service is no longer required to be provided by WIN or its Affiliates, or (iii) the date upon which the trigger event for termination occurs for such Service as set forth in the Services Attachment, subject to earlier termination of this Agreement or termination of all or a portion of the Services, as set forth in Section 12 hereof.

3

Notwithstanding the foregoing, CSL shall (and shall cause its Affiliates to) use commercially reasonable efforts to transition the Services to another, non-transitional provider as quickly as practicable or, as applicable, to cause CSL and/or its Affiliates to provide the Services.

3. Consideration for Services . As consideration for the Services, CSL shall pay to WIN the service fee for the Services as set forth in the Services Attachment and for all out-of-pocket costs and expenses from third parties actually incurred by WIN in the provision of the Services that are explicitly set forth in the applicable Services Attachment or otherwise approved in writing (including by electronic mail) by CSL’s Transition Representative or Service Representatives prior to WIN incurring such out-of-pocket expense; provided , however , WIN shall be excused from performance for Services to the extent WIN’s performance is delayed as a result of CSL’s pre-approval process for third-party costs and expenses (the “ Service Fee ”).

4. Terms of Payment .

(a) Not later than thirty (30) calendar days following the end of each calendar month during the Term, WIN shall submit to CSL in writing an invoice setting out in reasonable detail each Service performed by WIN during the preceding month and the related Service Fee. CSL shall pay the amount shown on each such invoice no later than thirty (30) calendar days after receipt of such invoice; payment shall be made without withholding or deduction of any kind. If such amount is not received by WIN within such 30-day period, CSL shall also pay WIN interest from and after the last day of such 30-day period following receipt of such invoice, at a rate per annum equal to the prime lender rate as reported on the last day of the calendar month in respect of such invoice by the Wall Street Journal .

(b) Any transition, excise, sales, use or similar tax charged to, assessed on or incurred by the rendering of the Services shall be split equally between WIN, on the one hand, and CSL, on the other hand, and CSL’s share shall be paid to WIN in addition to the Service Fees; provided , however , WIN shall be solely responsible for its own income taxes.

(c) Should CSL dispute in good faith any portion or the entire amount due on any invoice or require any adjustment to an invoiced amount, CSL shall promptly notify WIN in writing of the nature and basis of the dispute and/or adjustment within fifteen (15) business days after CSL’s receipt of such invoice. If CSL fails to notify WIN within such 15-day period, the invoiced amount shall be deemed to be accurate and correct and shall not be subject to dispute or contest by CSL or any Affiliate thereof. In the event CSL timely delivers notice of a dispute and/or adjustment, the Parties shall use their reasonable best efforts to resolve such matter within thirty (30) calendar days. WIN shall reimburse CSL within fifteen (15) business days following, as applicable (i) agreement by the Parties of any excess payment made by CSL in respect of Services, or (ii) resolution of any disputed amounts paid in excess of the amount of the costs of such Services, in either case, with interest from and after the date payment was made by CSL through, but excluding, the date of reimbursement by WIN, at the rate per annum equal to the prime lender rate as reported on the last day of the calendar month in respect of the applicable invoice by the Wall Street Journal .

(d) WIN and CSL agree to remit payments to each other in accordance with the terms and conditions set forth in the Billing and Remittance Agreement between the Parties.

4

5. Method of Payment . All amounts payable by CSL hereunder shall be remitted to WIN in United States dollars to a bank to be designated in the invoice or otherwise in writing by WIN, unless otherwise provided for and agreed upon in writing by the Parties.

6. Accounting Records and Documents .

(a) WIN or its Affiliates shall be responsible for maintaining full and accurate accounts and records of all Services rendered pursuant to this Agreement and such additional information as CSL may reasonably request for purposes of their internal bookkeeping, accounting, operations and management. WIN shall maintain its accounts and records in accordance with past practice; provided , that , to the extent full and accurate information is not relied upon by WIN in the ordinary course of business with respect to any particular item, unit or market/sub-market, WIN shall maintain such accounts and records on the basis of appropriate and reasonable allocations. WIN shall keep such accounts and records available, during all reasonable business hours during the Term of this Agreement, at its principal offices, or at such other location as required by applicable Laws, for audit, inspection and copying by CSL and Persons, upon reasonable notice, authorized by them or any governmental agency having jurisdiction over CSL; provided , that , the costs or expenses incurred by CSL or WIN for any such audit, inspection or copying shall be the sole responsibility of CSL.

(b) At any time during the Term of this Agreement, CSL, or its authorized independent auditors or counsel, shall have the right to inspect and audit WIN’s accounts, books and records relating to the Services upon five (5) business days prior written notice during regular business hours and without undue disruption of the normal operations of WIN.

(c) All information CSL, its Affiliates and its other authorized Persons gain access to pursuant to this Section 6 shall be subject to the terms of the confidentiality provisions set forth in Section 13 of this Agreement.

7. Consents .

(a) If any consent or approval of, or notice to, any third party is required to implement the terms of this Agreement (“ Third Party Consent ”), CSL and WIN shall each use their respective reasonable endeavors to obtain any Third Party Consent as soon as reasonably practicable, each at the cost of CSL. If any such Third Party Consent is refused or not obtained within three (3) months after the Distribution Date, the Parties shall co-operate in good faith to agree and implement reasonable alternative arrangements which achieve the same commercial effect as that contemplated by this Agreement.

(b) If either Party so requests, the other Party shall provide all reasonable assistance in obtaining any Third Party Consent and neither Party will unreasonably do or omit to do anything which would cause any relevant third party to refuse to grant or to terminate or revoke any Third Party Consent.

8. Performance Standards . In providing the Services to CSL under this Agreement, WIN shall (and shall cause its Affiliates to) provide the Services in a timely and professional manner generally consistent with the past practices of WIN and its Affiliates in providing the same or similar Services to the CSL Business prior to the execution of the Distribution Agreement and in conformance in all material respects with any service levels set forth in the applicable Services Attachment. For purposes of clarity, the Parties agree that the

5

measure of such past performance shall be, except as otherwise agreed in writing by the Parties, that WIN shall provide each of the Services in substantially the same manner and with substantially the same level of care and service as the manner and the level of care and service with which such Service was provided during 2014.

9. No Representations or Warranties . WIN MAKES NO EXPRESS OR IMPLIED WARRANTY WITH RESPECT TO THE TRANSITION SERVICES, AT LAW OR IN EQUITY, INCLUDING, WITHOUT LIMITATION, WITH RESPECT TO MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE, AND ANY AND ALL REPRESENTATIONS OR WARRANTIES ARE HEREBY EXPRESSLY DISCLAIMED.

WIN shall have complete discretion to supervise and manage such employees and any third-party contractors providing the Services on behalf of WIN, and WIN is not required to continue employment for any specific individual personnel of WIN or its Affiliates or to maintain engagements with specific third-party contractors. No equipment or facility of WIN used in performing the Services for or subject to use by CSL shall be deemed to be transferred, assigned, conveyed or leased by such performance or use. WIN shall maintain appropriate security, maintenance and insurance coverage on such equipment or facility.

(b) Except as set forth in the Services Attachment, to the extent WIN or its Affiliates use any proprietary intellectual property rights owned by or licensed to WIN or its Affiliates in providing the Services, such proprietary intellectual property rights and any derivative works thereof, or modifications or improvements thereto, conceived or created as part of the provision of Services (“ Improvements ”) will, as between the Parties, remain the sole property of WIN or its Affiliate, as applicable, unless any such Improvement was created for CSL pursuant to a certain Service. If any Improvement is created for CSL pursuant to a certain Service or other proprietary intellectual property rights are created specifically for CSL pursuant to Services provided under the Services Attachment (a “ CSL Specific Improvement ”), such CSL Specific Improvement shall be owned by CSL. The applicable Party will and hereby does assign to the applicable owner designated above, and agrees to assign automatically in the future upon first recordation in a tangible medium or first reduction to practice, all of such Party’s right, title and interest in and to all Improvements, if any. All rights not expressly granted herein are reserved.

(d) Independent of, severable from, and to be enforced independently of any other enforceable or unenforceable provision of this Agreement, NO PARTY WILL BE LIABLE TO ANY OTHER PARTY (NOR TO ANY PERSON CLAIMING RIGHTS DERIVED FROM ANY OTHER PARTY’S RIGHTS) FOR PUNITIVE, EXEMPLARY, SPECIAL, CONSEQUENTIAL OR INDIRECT DAMAGES OF ANY KIND, INCLUDING, BUT NOT LIMITED TO, ANY LOSS OF USE, LOSS OF BUSINESS, LOSS OF PROFIT OR LOSS OF GOODWILL. Further, indemnification shall be limited to actual damages which in no event shall exceed the total amount of compensation payable to WIN hereunder.

(e) Except as otherwise provided in this Section 11 , WIN’s sole responsibility to CSL for errors or omissions in providing the Services shall be to re-perform such Services promptly and properly in a diligent manner, at no additional cost or expense; provided , however , that each Party shall use reasonable best efforts to detect any such errors or omissions and promptly advise the other Party of any such error or omission of which it becomes aware.

(c) Escalation Procedure . At the written request of a Party involved in the Dispute and in compliance with Section 17(b) , each Party shall appoint a knowledgeable, responsible representative to negotiate in good faith to resolve such Dispute (the “ Representatives ”).
