AGREEMENT

The Parties, intending to be legally bound, agree as follows:

At the Closing, upon the terms and subject to the conditions set forth in this Agreement, Seller shall sell, assign, transfer, and convey to Buyer, and Buyer shall purchase and acquire from Seller, the Purchased Units, free and clear of any Liens other than Permitted Liens.

(iii) a good standing certificate (or equivalent document), dated within 5 Business Days of the Closing, for each Seller Party issued by the Secretary of State of the jurisdiction in which such Seller Party was formed or organized;

-2-

(iv) a certificate of each Seller Party signed by an officer of such Seller Party (1) certifying that the conditions set forth in Sections 6.2(a) and 6.2(b) with respect to each Seller Party has been satisfied and (2) certifying and attaching all requisite resolutions or actions of the board of directors, general partner or member of such Seller Party approving the execution and delivery of this Agreement and the consummation of the Contemplated Transactions, including the removal of each of the officers and managers of the Company immediately prior to the Effective Time and appointment of new officers of the Company as of the Effective Time;

1.5 Net Working Capital Threshold. The Parties acknowledge that the Base Total Consideration has been based in part on the Company having a Net Working Capital as of the Effective Time equal to $47 million (the “Net Working Capital Threshold”). Attached hereto as Schedule 1.5 is (a) an estimated balance sheet of the Company as of November 30, 2011, which balance sheet has been prepared in accordance with GAAP, except as set forth on Schedule 1.5 (the “Estimated Balance Sheet”), and (b) a schedule with a calculation of the Net Working Capital of the Company as of November 30, 2011 (the “Estimated NWC Schedule”).

1.6 Net Working Capital Adjustment Procedure.

(a) For the purpose of confirming the Net Working Capital Threshold, Buyer shall prepare, or cause to be prepared, (i) a balance sheet of the Company as of the Effective Time, which balance sheet shall be prepared in substantially the same manner as the Estimated Balance Sheet (the “Final Balance Sheet”) and (ii) a schedule with a calculation of the Net Working Capital of the Company as of the Effective Time (the “Final Net Working Capital”), which schedule shall be prepared in substantially the same manner as the Estimated NWC Schedule (the “Final NWC Schedule”) and which Final Net Working Capital shall be calculated in substantially the same manner as the calculation of the Net Working Capital of the Company as of November 30, 2011 in the Estimated NWC Schedule.

(b) No later than 90 days after the Effective Time (or such later date as mutually agreed by Buyer and Seller), Buyer shall deliver to Seller the Final Balance Sheet and the Final NWC Schedule, including a worksheet showing the difference, if any, between the Final Net Working Capital and the Net Working Capital Threshold. If Buyer does not deliver the Final Balance Sheet and Final NWC Schedule in accordance with this Section 1.6(b) on or before the 90th day after the Effective Time (or such later date as mutually agreed by Buyer and Seller), Seller shall have the right to prepare the Final Balance Sheet and Final NWC Schedule on or before the 120th day after the Effective Time (or such later date as mutually agreed by Buyer and Seller), in which case the relative obligations of Buyer and Seller in the remainder of this Section 1.6 shall be switched. Buyer and Seller shall promptly provide to each other all documents reasonably requested by the other to verify any of the elements of working capital set forth in the Final Balance Sheet and Final NWC Schedule.

(c) Within 30 days after receipt by Seller of the Final Balance Sheet and Final NWC Schedule (the “Initial Review Period”), Seller shall notify Buyer in writing as to whether Seller agrees or disagrees with the Final Net Working Capital set forth on the Final NWC Schedule and, if Seller disagrees, such notice shall set forth in reasonable detail the particulars of such disagreement, including the calculation by Seller of the Final Net Working Capital (“Notice of Disagreement”). If Seller provides a notice pursuant to which it agrees with each of the components of the Final Balance Sheet and the Final NWC Schedule or does not provide a Notice of Disagreement within such 30-day period, then Seller shall be deemed to have accepted all of the amounts set forth in the Final Balance Sheet and the Final NWC Schedule, which shall then be final, binding, and conclusive for all purposes hereunder. If a Notice of Disagreement is timely provided, then Buyer and Seller shall use commercially reasonable efforts for a period of 30 days thereafter to resolve any disagreements with respect to the amounts identified in the Notice of Disagreement. Any item or amount to which no dispute is raised in the Notice of Disagreement shall be final, conclusive, and binding.

-4-

(d) If, at the end of the 30 day resolution period, Buyer and Seller are unable to resolve any disagreements as to items in a Notice of Disagreement, then Deloitte LLP (or such other nationally-recognized independent accounting firm as may be mutually selected by Buyer and Seller) shall be appointed as an expert to resolve any remaining disagreements, but in no case shall Deloitte LLP review or propose any resolution for any matters that have not been raised in the Notice of Disagreement. If Deloitte LLP is unwilling or unable to serve in such capacity and Buyer and Seller are not able to mutually select an alternative independent accounting firm that is willing and able to serve in such capacity, then Buyer shall within 10 days deliver to Seller a listing of 3 other nationally-recognized firms and Seller shall within 10 days after receipt of such list, select one of such 3 firms (such firm as is ultimately selected pursuant to the aforementioned procedures being the “Dispute Resolution Expert”). The Dispute Resolution Expert shall be charged with determining as promptly as practicable, but in any event within 30 days after the date on which such dispute is referred to the Dispute Resolution Expert, any unresolved disputed items required to determine the Final Net Working Capital. In resolving any such dispute:

(i) each of Buyer and Seller shall furnish to the Dispute Resolution Expert such workpapers and other documents and information relating to such objections as the Dispute Resolution Expert may request and are reasonably available to that Party (or its independent public accountants) and shall be afforded the opportunity to present to the Dispute Resolution Expert any material relating to the determination of the matters in dispute and to discuss such determination with the Dispute Resolution Expert;

(ii) the Dispute Resolution Expert may not adopt an amount for Final Net Working Capital that is less than the lowest amount proposed by either Buyer or Seller or greater than the highest amount proposed by either Buyer or Seller;

(iii) the determination of the Dispute Resolution Expert shall be final, binding, and conclusive for all purposes hereunder; and

(iv) all fees and costs of the Dispute Resolution Expert shall be paid 50% by Buyer and 50% by Seller.

(e) Following the final determination of Final Net Working Capital as set forth in this Section 1.6 the Parties agree as follows:

(i) If the Final Net Working Capital is less than the Net Working Capital Threshold (such shortfall, the “Final NWC Shortfall”), Seller shall promptly (but in any event within 5 Business Days) pay by wire transfer in immediately available funds to Buyer, to an account or accounts designated by Buyer in writing, an amount equal to the Final NWC Shortfall.

-5-

(ii) If the Final Net Working Capital exceeds the Net Working Capital Threshold (such excess, the “Final NWC Excess”), Buyer shall promptly (but in any event within 5 Business Days) pay by wire transfer in immediately available funds to Seller, to an account or accounts designated by Seller in writing, an amount equal to the Final NWC Excess.

(f) Buyer will, or will cause the Company to, promptly pay to Seller all Stale Receivables received by Buyer or the Company from and after the Effective Time.

1.7 Adjustments to Total Consideration. All amounts to be paid under this Article 1 shall be deemed to be adjustments to the Total Consideration for tax purposes.

No equity interests of the Company are reserved for issuance.

(c) All issued and outstanding Units have been duly authorized, are validly issued and outstanding, fully paid, and nonassessable. None of the equity interests of the Company have been offered, issued, sold, or transferred in violation of any applicable Law or pre-emptive or similar rights.

2.5 Subsidiaries. Except as set forth on Schedule 2.5, the Company does not, directly or indirectly, own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any Person, nor does it participate in any manner in any joint venture, partnership, or similar arrangement.

2.6 Title to and Condition of Assets; Sufficiency of Assets.

(a) The Seller Parties have delivered or made available to Buyer copies of the deeds, leases, assignments, and other instruments (as recorded) by which the Company acquired the real property interests owned by the Company, and copies of all title insurance policies, opinions, abstracts, and surveys in the possession of the Company and relating to such real property interests.

(b) The Company has (i) good and defensible title to all of its real property interests and (ii) good and valid title to all of its personal property used in the ordinary conduct of business, except (A) for such defects in title as would not, individually or in the aggregate, reasonably be expected to materially and adversely impact the ability of the Company to (1) conduct its business in accordance with past practices and (2) perform its obligations under its Material Contracts, (B) for Rights-of-Way addressed in Section 2.7, and (C) interests of other parties set forth in the COO Agreements.

-8-

2.7 Rights-of-Way.

(a) The Company has good and defensible title to all of the Rights-of-Way, free and clear of all Liens other than Permitted Liens and has held all of the Rights-of-Way in a manner that does not violate in any material respect the terms of any such Rights-of-Way. All of the Rights-of-Way are valid and enforceable. The Company has not received notice from any grantor of any such Right-of-Way of any default or dispute relating thereto. No event has occurred which, with notice or the lapse of time or both, would give rise to the revocation, modification, or termination of any Right-of-Way, except as would not be material to the conduct of the Company’s business in substantially the same manner as is currently being conducted. The Rights-of-Way constitute all easements, rights-of-way, permits, servitudes, licenses, leasehold estates, and similar rights related to real property that are necessary for the Company to (i) conduct its business in substantially the same manner as is currently being conducted and (ii) perform its obligations that are currently required to be performed under its Material Contracts.

2.8 Litigation. Schedule 2.8 contains a complete and accurate list of all unsatisfied Orders to which the Company or the Assets are subject and all Proceedings of any Person or Governmental Body to which the Company is a party or to which the Assets are subject. Except as set forth Schedule 2.8, neither the Company nor the Assets are (a) subject to any unsatisfied Order or (b) a party or subject to, or, to the Knowledge of Seller Parties, threatened to be made a party or subject to, any Proceeding of any Person or Governmental Body that has not been finally resolved by litigation, settlement, or otherwise. There are no pending Proceedings or, to the Knowledge of Seller Parties, threatened Proceedings against a Seller Party relating to the Transaction Documents or any of the Contemplated Transactions.

-9-

2.9 Compliance with Laws; Permits.

(a) The Company is in compliance in all material respects with all Laws or Orders applicable to the Company and the use, ownership, and operation of the Assets.

ARTICLE 5 — TAX MATTERS

5.1 Payment of Taxes. Seller shall file all Tax Returns required to be filed by or with respect to the Company for a Pre-Effective Time Tax Period. Seller shall indemnify the Buyer Indemnified Parties for all Liabilities incurred for, arising out of, or relating to any Taxes incurred or paid with respect to the Company and the Assets for any Pre-Effective Time Tax Period to the extent such Taxes are not actually taken into account in the calculation of the Final Net Working Capital. Buyer shall file all other Tax Returns required to be filed by or with respect to the Company and shall pay all other Taxes owed. In the case of any Tax period that includes but does not end on the Effective Time (a “Straddle Period”), the portion of any Taxes, other than property Taxes (which shall be allocated between the Pre-Effective Time Tax Period and the Post-Effective Time Tax Period in accordance with Section 5.4), allocable to the Pre-Effective Time Tax Period shall be determined from the books and records of the Company or its Affiliates, as applicable, as though the taxable year of the Company terminated at the close of business on the day prior to the Effective Time. Buyer and Seller shall each provide the other with all information reasonably necessary to prepare a Tax Return. The indemnification procedures set forth in Section 8.5 shall apply to the indemnification provided in this Section 5.1.

5.2 Allocation of Total Consideration. The Total Consideration represents the amount agreed upon by Buyer and Seller to be the aggregate fair market value of the Purchased Units. The Total Consideration shall be allocated among the assets of the Company for Tax purposes in a manner consistent with Section 1060 of the Code and the Treasury Regulations promulgated thereunder, based upon the fair market value of such assets. Such Total Consideration allocation shall be agreed upon and memorialized in a schedule on or prior to the Closing Date. Seller and Buyer agree to file all required Tax Returns (including IRS Form 8594 and any amended Tax Returns or claims for refund) in a manner consistent with the Total Consideration allocation agreed upon under this Section 5.2 and neither Seller nor Buyer shall take any position inconsistent with such allocation on any Tax Return or otherwise, unless required to do so by Applicable Law or a “determination”, within the meaning of Section 1313(a)(1) of the Code. The Total Consideration allocation may be revised, from time to time, by a mutual written consent of Seller and Buyer, to reflect any matters that require updating (including Total Consideration adjustments, if any).

5.3 Responsibility for Tax Audits and Contests. Seller shall control any audit or contest with respect to a Pre-Effective Time Tax Period and Buyer shall control any other audit or contest; provided, however, that the Party with the greater potential Tax Liability shall control any audit or contest with respect to a Straddle Period. Neither Buyer nor Seller shall settle any

-25-

audit or contest in a way that would adversely affect the other Party without the other Party’s written consent, which the other Party shall not unreasonably withhold. Buyer and Seller shall each provide the other with all information reasonably necessary to conduct an audit or contest with respect to Taxes.

5.4 Property Taxes. Seller shall be responsible for property Taxes levied with respect to the Assets attributable to the Pre-Effective Time Tax Period and the Company shall be responsible for property Taxes levied with respect to the Assets attributable to the Post-Effective Time Tax Period. Property Taxes levied with respect to the Assets for the Tax period (for purposes of property Taxes, the term “Tax period” means the period beginning on the assessment date for property Taxes through the day before the next assessment date for such property Taxes) that contains the Effective Time shall be prorated between the Pre-Effective Time Tax Period and the Post-Effective Time Tax Period based on the relative number of days prior to the Effective Time and on and after the Effective Time during the Tax period. Except to the extent actually taken into account in the calculation of the Final Net Working Capital with respect to property Taxes, upon receipt of any ▇▇▇▇ for such property Taxes, (a) the Company or Seller shall present, whether before or after the payment of such ▇▇▇▇, a statement to Seller or the Company, as applicable, setting forth the amount of reimbursement to which the presenting Person is entitled under this Section 5.4 together with such supporting evidence as is reasonably necessary to calculate the proration amount and (b) the proration amount shall be paid promptly but in no event later than 10 days after receipt of such statement.

5.5 Tax Sharing Agreements. The Company’s participation in any Tax sharing agreement with Seller or any other Person shall be terminated as of the Closing Date and shall have no further effect with respect to any Pre-Effective Time Tax Period or Post-Effective Time Tax Period.

5.6 Tax Refunds. Seller shall be entitled to any refund of Taxes paid with respect to a Pre-Effective Time Tax Period. The Company shall be entitled to any refund of Taxes paid with respect to a Post-Effective Time Tax Period. Refunds for a Straddle Period shall be apportioned based on the Taxes that were paid by or on behalf of Buyer and Seller. If a Party receives a refund to which the other Party is entitled, the Party receiving the refund shall pay it to the Party entitled to the refund within 2 Business Days after receipt.

5.7 Liability for Transfer Taxes. In the event any sales (including bulk sales), use, documentary, stamp, registration, transfer, conveyance, excise, recording, license, stock transfer stamps, or other similar taxes (“Transfer Taxes”) are incurred as a direct result of Buyer’s purchase of the Purchased Units pursuant to this Agreement, Buyer shall be responsible for the payment of such Transfer Taxes. The party required by law to file all necessary Tax Returns relating to such Transfer Taxes shall prepare and file such Tax Returns and Buyer and Seller shall each, and shall each cause their Affiliates to, cooperate in the timely preparation and filing of, and join in the execution of, any such Tax Returns. Buyer, Seller, and their respective Affiliates shall use their commercially reasonable efforts to mitigate, reduce, or eliminate any Transfer Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

-26-

5.8 Tax Treatment of Transaction. Buyer and Seller agree that for federal income Tax purposes, since the Company is a disregarded entity, the purchase and sale of the Purchased Units hereunder will be treated as a sale of the assets of the Company. The Parties agree that the transfer of ownership of the Purchased Units will occur at the Effective Time and that all of the benefits and burdens of ownership related to the Purchased Units will remain with the Seller until the Effective Time.

8.5 Indemnification Procedures.

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by prompt notice (a “Claim Notice”) by the Buyer Indemnified Party or Seller Indemnified Party seeking indemnification (the “Indemnified Party”) to the Party from whom indemnification is sought (the “Indemnifying Party”); provided, however, that failure to so notify the Indemnifying Party shall not preclude the Indemnified Party from any indemnification which it may claim in accordance with this Article 8 except to the extent that the Indemnifying Party can demonstrate actual loss and prejudice as a result of such failure. The Indemnifying Party shall, within 30 days after its receipt of a Claim Notice, notify the Indemnified Party in writing whether the Indemnifying Party admits or disputes the claim described in the Claim Notice. If the Indemnifying Party gives written notice that it admits the indemnification claim described in the Claim Notice, then the Indemnified Party shall be entitled to indemnification pursuant to the provisions of this Article 8, and subject to the limitations hereof, with respect to the estimated amount of Losses stated in the Claim Notice. If the Indemnifying Party notifies the Indemnified Party in writing that it disputes the claim for indemnification, or that it admits the entitlement of the Indemnified Party to indemnification under this Article 8 with respect thereto but disputes the amount of the Losses in connection therewith, then in either of such cases the indemnification claim described in the Claim Notice shall be a disputed indemnification claim that must be resolved by settlement between the Indemnified Party and the Indemnifying Party or by Proceedings commenced in an appropriate court of competent jurisdiction by either the Indemnifying Party or the Indemnified Party or by any other mutually agreeable method.

(b) In the event that any Proceedings shall be instituted or that any claim or demand shall be asserted by any third party in respect of which indemnification may be sought under Section 8.3 (a “Third Party Claim”), the Indemnified Party shall promptly notify the Indemnifying Party in writing of the assertion of such Third Party Claim. The failure of the Indemnified Party to give timely notice of any Third Party Claim shall not release, waive, or otherwise affect the Indemnifying Party’s obligations with respect thereto, except to the extent that the Indemnifying Party can demonstrate actual loss and prejudice as a result of such failure. Subject to the provisions of this Section 8.5, the Indemnifying Party shall have the right, at its sole expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the Indemnified Party, and to defend against, negotiate, settle, or otherwise deal with any Third Party Claim which relates to any Losses indemnified by it hereunder; provided, however, that the Indemnifying Party shall have acknowledged in writing to the Indemnified Party its unqualified obligation to indemnify the Indemnified Party as provided hereunder. If the Indemnifying Party elects to defend against, negotiate, settle, or otherwise deal with any Third Party Claim which relates to any Losses indemnified by it hereunder, it shall within 10 days prior to the time any response to a Third Party Claim is required, and in any event within 30 days of the Indemnified Party’s receipt of written notice of the assertion
