2.1    Purchase Price. The aggregate purchase price (the “Purchase Price”) for the Purchased Assets shall be (a) One Hundred Million Dollars ($100,000,000) (the “Base Purchase Price”), plus (b) the amount, if any, of all capital costs and expenses in respect of the Purchased Assets paid by Sellers prior to the date upon which the Proposed Final Settlement Statement is due to Buyer pursuant to Section 2.3(b) and either (i) incurred after October 1, 2013 (the “Capital

Date”) and prior to the date hereof as set forth on Schedule 5.3 or (ii) incurred between the date hereof and the Closing Date in accordance with Section 5.3(c)(vii) ((i) and (ii) collectively, the “Capital Adjustment”), minus (c) the amount, if any, of all costs and expenses incurred by Buyer to create “as-built” maps for the Purchased Assets as set forth on Schedule 2.1.

(b)    As soon as practicable but no later than 90 days after the Closing, the Seller Representative shall prepare and deliver to Buyer a statement in the same form of and on the same basis as the Preliminary Settlement Statement (the “Proposed Final Settlement Statement”), which sets forth the Seller Representative’s calculation of the final Purchase Price and each adjustment or payment that was not finally determined on the Preliminary Settlement Statement. Each Party shall, during normal business hours, grant and provide the other Party access to the Purchased Records in the possession or control of such Party for the purposes of

conducting an audit of the information set forth in the Proposed Final Settlement Statement.

(c)    Within 30 days following receipt by Buyer of the Proposed Final Settlement Statement, Buyer shall, if applicable, provide the Seller Representative with a written objection (a “Notice of Disagreement”) detailing Buyer’s objections, if any, to the Seller Representative’s calculation of the final Purchase Price. To the extent such written notice is not delivered by Buyer within such time period, the Seller Representative’s calculation of the final Purchase Price, and each component thereof, shall become final and binding upon the Parties.

(d)    Any disagreement between Buyer and Sellers regarding the Seller Representative’s calculation of the final Purchase Price that cannot be resolved within 30 days after the date of the Notice of Disagreement shall be resolved by Audit Firm, who shall calculate the final Purchase Price in a manner consistent with the Preliminary Settlement Statement and this Agreement in all respects.

The determination of the Audit Firm shall be expressly limited to the determination of the final Purchase Price, and the Audit Firm will not render any decision or have any authority to render a decision with respect to any other matter relating to this Agreement, including with respect to any alleged breach of a representation, warranty or covenant by any Party. In making such determination, the Audit Firm shall consider only those items and amounts in the Proposed Final Settlement Statement with which Buyer has disagreed and which are set forth in the Notice of Disagreement. In no event shall the final Purchase Price as determined by the Audit Firm be more favorable to Sellers than reflected on the Proposed Final Settlement Statement by the Seller Representative nor more favorable to Buyer than shown in the proposed changes set forth in the Notice of Disagreement. Buyer and Sellers shall use commercially reasonable efforts to cause the Audit Firm to render its decision within 15 business days after such points of disagreement are submitted to the Audit Firm. Subject to the provisions set forth in this Section 2.3(d), the decision of the Audit Firm shall be set forth in writing and shall be conclusive and binding on the Parties and subject to judicial enforcement. The fees charged by the Audit Firm shall be borne 50% by Buyer and 50% by Sellers, and each Party shall bear all of its own costs and expenses associated with the submission of any disputed matters to the Audit Firm.

(e)    If the final Purchase Price, as determined pursuant to this Section 2.3, exceeds (i) the Base Purchase Price, plus (ii) the Seller Representative’s good faith estimate of the Capital Adjustment (the “Closing Payment”), then Buyer shall pay to Sellers the amount of such excess. If the final Purchase Price, as determined pursuant to this Section 2.3, is less than the Closing Payment, then Sellers shall pay to Buyer the amount of such deficiency. Any payment shall be made within three days after the date the final Purchase Price is deemed to be finally determined pursuant to this Section 3.4 via wire transfer of immediately available funds to the account(s) designated in writing by the Party entitled to such payment.

5.2    Access. From and after the date of this Agreement and until the Closing Date, Sellers shall permit Buyer’s officers, employees, agents and advisors, at Buyer’s sole risk and expense, to (i) have reasonable access to the Purchased Assets (so long as such access occurs during normal business hours or at mutually agreeable times and does not unreasonably interfere with the operation of the Purchased Assets) to observe the condition, use and operation of the Purchased Assets and to facilitate the transactions contemplated by this Agreement and (ii) otherwise perform due diligence activities, including title searches. Buyer agrees to maintain the confidentiality of all information acquired by Buyer pursuant to this Section 5.2 in

accordance with the terms of the Confidentiality Agreement (as defined in Section 5.11 below). Buyer agrees to indemnify, defend and hold harmless the Seller Indemnified Parties from and against any and all Damages (as defined in Section 7.2 below) arising out of or relating to access to the Purchased Assets prior to the Closing by Buyer, even if caused in whole or in part by the negligence (whether sole, joint or concurrent), strict liability or other legal fault of any Seller Indemnified Parties (but excluding gross negligence or willful misconduct on the part of any Seller Indemnified Parties).

5.3    Conduct of Business. From and after the date of this Agreement and until the Closing Date, each Seller agrees that:

(vi)    abandon or release any Right of Way or Permit;

(viii)    enter into any Affiliate Agreement; or

(ix)    waive, compromise or settle any material rights under any Right of Way or Contract.

Buyer’s approval of any action restricted by this Section 5.3 shall not be unreasonably withheld or delayed and shall be considered granted 10 days (unless a shorter time is reasonably required by the circumstances and such shorter time is specified in the Seller Representative’s notice) after the Seller Representative’s notice to Buyer requesting such consent unless Buyer notifies the Seller Representative to the contrary during that period. Notwithstanding the foregoing provisions of this Section 5.3, in the event of an emergency, Sellers may take such action as reasonably necessary to prevent damage to people or property and shall notify Buyer of such action promptly thereafter.

5.4    Consents. From and after the date of this Agreement and until the Closing Date, Sellers shall use commercially reasonable efforts to obtain the written consent from any person or entity with respect to any Right of Way or Contract that is required to permit the sale, transfer and assignment of such Right of Way or Contract pursuant to the terms and conditions thereof (the “Consents”). All such Consents are set forth on Schedule 5.4. Notwithstanding anything in this Agreement to the contrary, neither Party shall be obligated to make any payments to any holder of any Consent or incur any other material burden in order to comply with the requirements set forth in this Section 5.4 and the failure to obtain any such Consent shall not be deemed a breach of any covenant of any Party hereunder.

5.6    Transfer Taxes. Buyer shall pay all sales, use, gross receipts, transfer, real property transfer, documentary stamp, recording and other similar taxes arising from and with respect to the purchase and sale of the Purchased Assets.

Buyer shall be solely responsible for recording of the Partial Assignments and any other documents related to the conveyance of the Purchased Assets and shall promptly furnish Sellers with either the recorded originals or with the recording information thereof. All recording and filing shall be at the sole cost and expense of Buyer.

5.8    Allocation of Taxes.

(a)    All ad valorem real property taxes, personal property taxes, fees or assessments for the calendar year 2014 due with respect to the Purchased Assets or payable by Sellers pursuant to the terms of any Rights of Way or Contracts shall be prorated between Sellers, on the one hand, and Buyer, on the other hand, as of the Closing Date on a calendar year basis, using the calendar year 2013 tax rates and assessments by the appropriate Governmental Authority; provided, however, that, if the taxes for 2014 are thereafter determined to be more or less than the taxes for 2013 (after any appeal of the assessed valuation thereof is concluded), Buyer and Sellers promptly shall adjust the proration of such taxes based on actual taxes paid with respect to 2014, and Sellers or Buyer, as the case may be, shall pay to the other any amount required as a result of such adjustment. The portion of such taxes allocable to the portion of calendar year 2014 ending on the Effective Time shall be deemed to be (A) the amount of such

taxes for the entire period multiplied by (B) a fraction, the numerator of which is the number of calendar days in the portion of calendar year 2014 ending on the Effective Time and the denominator of which is 365. All special taxes or assessments prior to the end of 2014 shall be prorated as set forth above. If any Party shall pay such taxes for which it is entitled to be reimbursed because of such proration, the other Party responsible therefor shall promptly reimburse the party so paying upon notice of the amount paid by such Party.

(b)    Sellers shall be responsible for any sales, use, excise, environmental, custom or other like tax, duty, fee or assessment or charge imposed by a Governmental Authority that is associated with the Purchased Assets prior to the Effective Time.

(c)    Sellers shall be entitled to any refunds or credits of taxes paid with respect to the Purchased Assets to the extent attributable to the period prior to the Effective Time. Buyer shall be entitled to any refunds or credits of taxes paid with respect to the Purchased Assets to the extent attributable to the period after the Effective Time.

(d)    Sellers shall be responsible for the preparation and filing of any tax returns, consistent with past practice, and the payment of any tax required to be paid in connection therewith related to Sellers that are required to be filed for taxable periods ending prior to or on the Closing Date. Buyer shall be responsible for the preparation and filing of all tax returns and the payment of any tax required to be paid in connection therewith related to Buyer that are required to be filed for taxable periods ending after the Closing Date.

(e)    Each Party shall be responsible for its own income taxes, if any, which may result from the transactions contemplated by this Agreement.

(f)    No Seller shall take or omit to take any action outside of the ordinary course of business or in a manner inconsistent with past practice if such action or omission could have the effect of increasing the tax liability relating to any of the Purchased Assets, Buyer or any of Buyer’s Affiliates, unless required by applicable Laws and Regulations.

5.9    Transaction Expenses. Except as expressly provided otherwise herein, each Party shall pay its own expenses and the fees and expenses of its counsel, accountants, consultants and other experts and representatives incurred in connection with the execution and delivery of this Agreement and the other Transaction Documents and the consummation of the transactions contemplated hereby and thereby.

5.10    Maintenance of Books and Records. At the Closing, Sellers shall deliver to Buyer the Records. Buyer and Sellers shall cooperate fully with one another after the Closing so that (subject to any limitations that are reasonably required to preserve any applicable attorney-client or other legal privilege) each Party has access to the business records, contracts and other information existing at the Closing Date and relating in any manner to the Purchased Assets (whether in the possession of Sellers or Buyer). No files, books or records existing at the Closing Date and relating in any manner to the Purchased Assets shall be destroyed by any Party for a period of two years after the Closing Date (or such longer period as is required by applicable Laws and Regulations). The access to files, books and records contemplated by this Section 5.10 shall be during normal business hours and upon not less than two days prior written

request, shall be subject to such reasonable limitations as the Party having custody or control thereof may impose to preserve the confidentiality of information contained therein, and shall not extend to material subject to a claim of privilege unless expressly waived by the Party entitled to claim the same.

5.11    Confidentiality. The respective obligations of the Parties with regard to the use and disclosure of information provided to one Party by the other are set forth in the Confidentiality Agreement dated September 5, 2013 (the “Confidentiality Agreement”), between PVOG and American Midstream Partners, L.P. (“AMID”), an Affiliate of Buyer. Notwithstanding anything in the Confidentiality Agreement or this Agreement to the contrary, Sellers and Buyer shall consult with each other with regard to all publicity and other public releases concerning this Agreement and the transactions contemplated hereby; provided, however, that nothing contained in this Agreement or the Confidentiality Agreement shall restrict any Party or any Affiliate of any Party from making any disclosure required by applicable Laws and Regulations or the applicable rules of any stock exchange. Sellers shall use commercially reasonable efforts to (i) assign all confidentiality agreements relating to the sale of the Purchased Assets to Buyer or (ii) if such assignment cannot be made, cause any person or entity which received confidential information about the Purchased Assets to return to Sellers or destroy such confidential information.

5.12    Release of Bonds. Upon the request of Sellers, Buyer shall assist Sellers in a commercially reasonable manner to release or cause the release or cancellation any bonds, letters of credit or guarantees posted by any Seller with Governmental Authorities and relating to the Purchased Assets.

5.15    Government Reviews. As promptly as practicable after the date of this

Agreement (but in any event within three business days of this date of this Agreement), Sellers and Buyer shall in a timely manner (a) make all required filings, if any, with and prepare applications to and conduct negotiations with each Governmental Authority as to which such filings, applications or negotiations are necessary or appropriate in connection with the consummation of the transactions contemplated hereby, specifically including, but not limited to, the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (b) provide such information as each may reasonably request to make such filings, prepare such applications and conduct such negotiations and (c) request early termination or waiver of any applicable waiting period under the HSR Act. To the extent reasonably practicable, Sellers and Buyer shall each have the right to review in advance all information relating to such Party that is disclosed for any filing. Each Party shall cooperate with and use all commercially reasonable efforts to assist the other with respect to such filings, applications and negotiations and shall promptly furnish each other with copies of any written communications delivered to such Party from any Governmental Authority. The applicable filing fee in connection with the filings to be made under the HSR Act shall be borne 50% by Buyer and 50% by Sellers.

5.16    Further Assurances. At or after the Closing, any Party, at the request of any other Party and without additional consideration, shall execute and deliver to the requesting Party all such further assignments, deeds, agreements, contracts, instruments and other documents as the requesting Party may reasonably request in order to perform, accomplish, perfect or record, if reasonably necessary, the sale, assignment, transfer and delivery to Buyer of the Purchased Assets as contemplated by this Agreement, to obtain the Customary Post-Closing Consents and to otherwise carry out the intention of this Agreement.

5.17    Financial Information. Sellers hereby agree to provide to Buyer access to such records, materials and documents in Sellers possession as may be reasonably requested from time to time by Buyer and its auditors in connection with the completion and delivery of such information as is required by the Securities and Exchange Commission to be included in any periodic report to be filed by AMID under the Securities Exchange Act of 1934, as amended, with respect to the Gathering Assets.

5.18    Rights-of-Way. Sellers shall use all commercially reasonable efforts to (a) procure and record valid rights-of-way across the leases set forth on Schedule 5.18 (the “Necessary ROWs”) and (b) record (to the extent not already recorded) all of the Rights of Way set forth on Schedule 1.1(b).

5.19    Replacement of Drip Tanks. Buyer acknowledges and agrees that the drip tanks currently used to operate the Gathering Assets are not Purchased Assets and, consequently, Buyer will need to procure and install new drip tanks for the operation of the Gathering Assets following the Closing. Buyer shall procure and install such new drip tanks within 90 days following the Closing Date. During such 90-day period, Sellers shall allow Buyer to continue to use Sellers’ existing drip tanks in connection with the operation of the Gathering Assets. Buyer agrees to indemnify, defend and hold harmless the Seller Indemnified Parties from and against any and all Damages arising out of or relating to Buyer’s use of Sellers’ existing drip tanks, even if caused in whole or in part by the negligence (whether sole, joint or concurrent), strict liability or other legal fault of any Seller Indemnified Parties (but excluding gross negligence or willful misconduct on the part of any Seller Indemnified Parties).

Failure of the Indemnified Party to give such notice shall not relieve the Indemnifying Party from liability on account of this indemnification, except if and to the extent that the Indemnifying Party is actually prejudiced thereby.

(b)    The Indemnifying Party, at its own expense, shall have the right, exercisable within 30 days of receipt of notice of the Third Party Claim, to assume the defense of the Indemnified Party against the Third Party Claim so long as (i) the Indemnifying Party proceeds in good faith and in a timely manner and (ii) such Third Party Claim involves (and continues to involve) solely monetary damages.

(c)    So long as the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 7.4(b) above, (i) the Indemnified Party may retain separate co‑counsel at its sole cost and expense and participate in the defense of the Third Party Claim, it being understood that the Indemnifying Party shall pay all costs and expenses of counsel for the Indemnified Party (A) for all periods prior to such time as the Indemnifying Party has notified the Indemnified Party that it has assumed the defense of such Third Party Claim and (B) if there is a conflict of interest between the Indemnifying Party and the Indemnified Party, (ii) the Indemnified Party shall not file any papers or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), and (iii) the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed).

(d)    The Parties shall use commercially reasonable efforts to minimize Damages from Third Party Claims and shall act in good faith and in a timely manner in responding to, defending against, settling or otherwise dealing with Third Party Claims. The Parties shall also cooperate in any such defense and give each other reasonable access to all information relevant thereto. Whether or not the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnifying Party shall not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into without the Indemnifying Party’s prior written consent, which consent shall not unreasonably withheld or delayed. Notwithstanding the foregoing, the Indemnified Party shall have the sole and exclusive right

to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such claim involves equitable or other non‑monetary relief.

7.5    Other Limitations on Indemnification.

(a)    No Party shall have any liability pursuant to Section 7.2(a) or Section 7.3(a) above with respect to any breach of any representation or warranty (other than any Fundamental Representation) unless and until the aggregate amount of all of the Damages to the Buyer Indemnified Parties exceeds $2,000,000 (the “Indemnification Threshold”), in which case the Buyer Indemnified Parties shall be entitled to indemnification only to the extent of the excess over the Indemnification Threshold. There shall be no threshold or deductible with respect to (i) Sellers’ obligations to Buyer pursuant to Section 7.2(a) above with respect to any breach of any Fundamental Representation or pursuant to Section 7.2(b) above or (ii) Buyer’s obligations to Sellers pursuant to Section 7.3(b) or Section 7.3(c).

(b)    The aggregate liability of any Party pursuant to this Article 7 shall in no event exceed, individually or in the aggregate, $15,000,000; provided, however, that subject to Section 7.5(c) below, (a) Buyer’s liability pursuant to Section 7.3(b) above with respect to any covenant (including Buyer’s liability to fund the Purchase Price at the Closing) and Section 7.3(c) and (b) Seller’s liability pursuant to Section 7.2(a) with respect to any Fundamental Representation and Section 7.2(b) with respect to any covenant, shall, in each case, be without limit.

(c)    Under no circumstances shall any Party be liable to any other Party for any indirect, contingent, consequential, unforeseen, exemplary or punitive, special Damages of any nature (including lost profits); provided, however, that any such Damages recovered by any third party for which a Party owes another Party an indemnity under this Agreement shall not be waived.

(d)    The Parties will make appropriate adjustments for any insurance proceeds actually received by the Indemnified Party in determining Damages for purposes of this Article 7. All indemnification payments under this Article 7 will be deemed to be adjustments to the amounts paid to Sellers pursuant to Article 2. Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement.

(e)    Each Indemnified Party seeking indemnification hereunder shall use commercially reasonable efforts to mitigate any Damages that it asserts under this Article 7, but any reasonable costs and expenses (other than internal costs and expenses) incurred in connection therewith shall constitute Damages.

7.6    Exclusive Remedy. IN THE ABSENCE OF FRAUD, AFTER THE CLOSING THE RIGHT OF THE PARTIES TO ASSERT INDEMNIFICATION CLAIMS AND RECEIVE INDEMNITY PAYMENTS UNDER THIS AGREEMENT IS THE SOLE AND EXCLUSIVE RIGHT AND REMEDY EXERCISABLE BY THE PARTIES WITH RESPECT TO ANY DAMAGES ARISING OUT OF ANY BREACH BY ANY PARTY OF ANY

REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT OF SUCH PARTY SET FORTH IN THIS AGREEMENT OR OTHERWISE RELATING TO THE CONTEMPLATED TRANSACTIONS. NO PARTY WILL HAVE ANY OTHER REMEDY (STATUTORY, EQUITABLE, COMMON LAW OR OTHERWISE) AGAINST ANY OTHER PARTY WITH RESPECT TO SUCH MATTERS, AND ALL SUCH OTHER REMEDIES ARE HEREBY WAIVED. WITHOUT LIMITING THE FOREGOING, IN THE ABSENCE OF FRAUD, EACH OF THE PARTIES ACKNOWLEDGES AND AGREES THAT SUCH PARTY WILL NOT HAVE ANY REMEDY AFTER THE CLOSING FOR ANY BREACH OF ANY REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT, EXCEPT AS EXPRESSLY PROVIDED IN THIS ARTICLE 7.

7.7    Tax Treatment. Indemnification payments made pursuant to this Article 7 may be treated as adjustments of the Purchase Price as permitted by applicable Laws and Regulations.

8.1    Termination of Agreement. The Parties may terminate this Agreement as provided below:

(a)    Buyer and Sellers may terminate this Agreement by mutual written consent at any time prior to the Closing;

(b)    Buyer may terminate this Agreement by giving written notice to the Seller Representative (i) at any time prior to the Closing in the event that any Seller has breached in any material respect any representation, warranty or covenant contained in this Agreement, Buyer has notified the Seller Representative of the breach, and the breach has continued without cure for a period of 30 days after the notice of breach or (ii) at any time following February 28, 2014 (the “Termination Date”) if the Closing shall not have occurred on or before the Termination Date; or

(c)    Sellers may terminate this Agreement by giving written notice to Buyer (i) at any time prior to the Closing in the event that Buyer has breached in any material respect any representation, warranty or covenant contained in this Agreement, the Seller Representative has notified Buyer of the breach, and the breach has continued without cure for a period of 30 days after the notice of breach or (ii) at any time following the Termination Date if the Closing shall not have occurred on or before the Termination Date.

8.2    Effect of Termination.

(a)    In the event that this Agreement is terminated by either Party pursuant to Section 8.1 above, then, except as expressly hereinafter provided, this Agreement shall become void and have no effect; provided, however, that (i) the provisions of Sections 5.2, 5.11, 7.4, 7.5(c), 7.5(d) and 7.5(e), this Article 8, Article 9 and Article 10 shall survive any such termination and (ii) each Party shall, in all events, remain bound by and continue to be subject to the terms of the Confidentiality Agreement.

(b)    In the event that (i) Buyer terminates this Agreement pursuant to

Section 8.1(b) above, (ii) any Seller has knowingly taken any action or knowingly omitted to take any action where such action or omission to take any such action resulted in the breach or failure in any material respect of any of such Seller’s representations or warranties set forth herein or any covenants of such Seller which are to be performed or observed at or prior to the Closing and (iii) as of the date of such termination, Buyer has not breached in any material respect any representation, warranty or covenant of Buyer contained in this Agreement (including Buyer’s failure to consummate the transactions contemplated by this Agreement upon satisfaction of the conditions set forth in Section 6.2 above), then, subject to the limitations set forth in Section 7.5(c) above and this Section 8.2, Buyer shall be entitled to all remedies available at law or in equity (including specific performance to the extent that a court of competent jurisdiction determines that Buyer is entitled to such remedy).

(c)    In the event that (i) Sellers terminate this Agreement pursuant to Section 8.1(c) above , (ii) Buyer has knowingly taken any action or knowingly omitted to take any action where such action or omission to take any such action resulted in the breach or failure in any material respect of any of Buyer’s representations or warranties set forth herein or any covenants of Sellers which are to be performed or observed at or prior to the Closing and (iii) as of the date of such termination, no Seller has not breached in any material respect any representation, warranty or covenant of such Seller contained in this Agreement (including such Seller’s failure to consummate the transactions contemplated by this Agreement upon satisfaction of the conditions set forth in Section 6.1 above), then, subject to the limitations set forth in Section 7.5(c) above and this Section 8.2, Sellers shall be entitled to all remedies available at law or in equity (including specific performance to the extent that a court of competent jurisdiction determines that Sellers are entitled to such remedy).

(d)    In the event that (i) this Agreement terminates pursuant to Section 8.1 above and (ii) the conditions described in either Section 8.2(b) or Section 8.2(c) above have not been satisfied, then no Party shall have any obligations or liabilities hereunder except for the obligations and liabilities with respect to Sections 5.2 and 5.11, this Article 8, Article 9 and Article 10.

9.1    Appointment of Seller Representative.

(a)    By the execution and delivery of this Agreement, each Seller, effective immediately, hereby irrevocably constitutes and appoints PVOG as the true and lawful agent and attorney-in-fact with full authority and power of substitution to act in the name, place and stead of such Seller with respect to the performance of the obligations and rights of Sellers under this Agreement (the “Seller Representative”) and any action contemplated to be taken by the Seller Representative hereunder in connection therewith, including the power to (i) determine the Capital Adjustment, make adjustments to the Base Purchase Price and prepare the Preliminary Settlement Statement and the Proposed Final Settlement Statement, (ii) receive from Buyer any amounts owed to Sellers pursuant to this Agreement (including any amounts owed to Sellers pursuant to Section 2.3 or Section 2.5) and disburse to each Seller such Seller’s Pro Rata Share thereof, (iii) settle or pursue claims or controversies on behalf of Sellers with respect to amounts

owed by or to Sellers pursuant to this Agreement (including pursuant to Section 2.3(d)), (iv) give and receive any consents or notices required or permitted by this Agreement and (v) do or refrain from doing all such further acts and things, and execute, deliver and receive all such documents, waivers, extensions and amendments as the Seller Representative shall deem necessary or appropriate in its sole discretion in connection with the administration of this Agreement (and any such actions shall be binding on Sellers). Each of the Parties hereto covenants and agrees that it will not take any action to voluntarily revoke the power of attorney conferred in this Section 9.1. By its execution of this Agreement, PVOG hereby (1) accepts its appointment and authorization to act as the Seller Representative and attorney-in-fact on behalf of each Seller in accordance with the terms of this Agreement, and (2) agrees to perform its obligations under, and otherwise comply with, this Section 9.1.

(b)    Buyer, Sellers and any other Person may conclusively and absolutely rely, without inquiry, upon any action of the Seller Representative as the action of each Seller hereunder and in all matters referred to herein, and each Seller confirms all that the Seller Representative shall do or cause to be done in good faith by virtue of its appointment as the Seller Representative.

(c)    The Seller Representative may resign as the Seller Representative for any reason and at any time by written notice to Buyer and Sellers. If at any time the Seller Representative (or any successor Seller Representative) resigns from such Person’s position as the Seller Representative, a successor shall be designated by the mutual agreement of each Seller or, absent such mutual agreement, by a majority vote of the Sellers, as soon as practicable (but in no event later than 30 days after resignation of the Seller Representative or successor Seller Representative, as applicable), and the Parties shall thereafter be notified in writing of such designation; provided, however, that the Parties agree that a court of competent jurisdiction sitting in Harris County, Texas shall have the authority to appoint a successor Seller Representative in the event that a successor Seller Representative is not designated within the 30‑day period pursuant to the provisions hereof.

(d)    The Seller Representative shall have no duties except those which are expressly set forth herein. Each Seller hereby consents and agrees to all actions or inactions taken or omitted to be taken, in each case in good faith, by the Seller Representative under this Agreement. Notwithstanding anything in this Agreement to the contrary, including the provisions set forth in Article 7, each Seller hereby agrees to severally, and not jointly or jointly and severally, indemnify and hold harmless the Seller Representative from and against all Damages incurred in connection with the performance of its duties under this Agreement, excluding such Damages caused by the gross negligence, bad faith or willful misconduct of the Seller Representative. The Seller Representative shall be entitled and is hereby granted the right to set off and deduct any such unpaid, unsatisfied Damages from any amounts owed to a Seller pursuant to this Agreement.

(e)    Each of the Parties acknowledges and agrees that the Seller Representative shall not be liable, responsible or accountable in Damages or otherwise to any Party by reason of, arising from or relating to any action taken or failure to act on behalf of Sellers, unless caused by the gross negligence, bad faith or willful misconduct of the Seller Representative.

(f)    The Seller Representative shall be fully protected in relying in good faith upon the records of Sellers and upon such information, opinions, reports or statements presented to the Seller Representative by any of its accountants, consultants, brokers, financial advisors, legal counsel and other professionals as to matters the Seller Representative reasonably believes are within such Person’s professional or expert competence.

(g)    IN NO EVENT SHALL THE SELLER REPRESENTATIVE BE LIABLE, DIRECTLY OR INDIRECTLY, FOR ANY SPECIAL, INDIRECT OR CONSEQUENTIAL LOSSES OR DAMAGES OF ANY KIND WHATSOEVER (INCLUDING LOST PROFITS), EVEN IF THE SELLERS’ REPRESENTATIVE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES OR DAMAGES REGARDLESS OF THE FORM OF ACTION, UNLESS CAUSED BY THE GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OF THE SELLER REPRESENTATIVE.

(h)    EXCEPT TO THE EXTENT PROHIBITED BY LAW, EACH SELLER UNDERSTANDS AND AGREES THAT INDEMNIFICATION PURSUANT TO THIS SECTION 9.1 SHALL INCLUDE INDEMNIFICATION FOR THE SELLER REPRESENTATIVE’S OWN NEGLIGENCE OR UNDER THEORIES OF STRICT LIABILITY TO THE FULLEST EXTENT PERMITTED BY LAW, BUT SHALL EXCLUDE INDEMNIFICATION FOR THE SELLER REPRESENTATIVE’S GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT.

(i)    The provisions set forth in this Section 9.1 shall survive the resignation of the Seller Representative and the termination of this Agreement; provided, however, that the authorizations of the Seller Representative shall be effective only until its rights and obligations under this Agreement terminate by virtue of the termination of any and all obligations of Sellers and of Buyer under this Agreement.

(j)    The appointment and grant of power and authority by each Seller under this Section 9.1 is coupled with an interest and is irrevocable and shall not be terminated by any act of such Party or by operation of law, whether by the death or incapacity of such Party or by the occurrence of any other event.

9.2    Release of Seller Claims. Save and except for (i) any rights of any Seller under this Agreement and (ii) any claims of PVOG against any Seller for any outstanding System Costs as defined in that certain Gathering System Agreement dated as of June 1, 2012 by and among Sellers, each Seller, effective as of the Closing, for itself and its representatives and assigns, hereby finally, unconditionally, irrevocably and absolutely releases, acquits, remises and forever discharges each of the other Sellers and any of their Affiliates, predecessors, successors, assigns, agents and representatives (collectively, the “Releasees”) from any and all claims, counterclaims, demands, causes of action, liabilities costs, expenses and fees (including attorneys’ fees and court costs), existing as of the Closing accruing to such Seller in connection with the Purchased Assets (the “Claims”), and finally, unconditionally, irrevocably and absolutely waives any and all offsets and defenses, in each case related to any action, inaction, event, circumstance or occurrence occurring or alleged to have occurred on or prior to the Closing with respect to such Claims, whether known or unknown, absolute or contingent, matured or unmatured, foreseeable or unforeseeable, presently existing or hereafter discovered, at law, in equity or otherwise,

whether arising by statute, common law, in contract, in tort or otherwise, that such Seller may now have or that might subsequently accrue to it, including without limitation those against any current or former officer, director, manager, partner, employee or agent of any Releasee.

10.1    Amendment and Waiver. The Parties may, by mutual written agreement, amend this Agreement in any respect, and either party, as to such Party, may (i) extend the time for the performance of any of the obligations of the other Party; (ii) waive any inaccuracies in representations and warranties by the other Party; (iii) waive compliance by the other Party with any of the covenants or agreements contained herein and performance of any obligations by the other Party; and (iv) waive the fulfillment of any condition that is precedent to the performance by such Party of any of its obligations under this Agreement. To be effective, any such extension or waiver must be in writing and be signed by the Party providing such waiver or extension, as the case may be. No such extension or waiver by any Party, nor any waiver by any Party of any breach of any provision of this Agreement, shall operate or be construed as a waiver of any subsequent breach, whether or not similar. No failure or any delay by any Party in exercising any right, power or privilege under this Agreement or any of the other Transaction Documents shall operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege shall preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. Except as otherwise provided in this Agreement, the rights and remedies herein provided are cumulative and are not alternative.

10.2    Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, however, that no Party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of the other Party. Any transfer or assignment in violation of this Section 10.2 shall be void ab initio.

10.4    Severability.

10.5    No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall (i) confer on any person or entity other than the Parties (and the Indemnified Parties referred to in Article 7 above) and their respective successors or assigns any rights (including third party beneficiary rights), remedies, obligations or liabilities under or by reason of this Agreement, or (ii) constitute the Parties as partners or as participants in a joint venture. This Agreement shall not provide third parties with any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without reference to the terms of this Agreement. No third party shall have any right, independent of any right which may exist irrespective of this Agreement, under or granted by this Agreement, to bring any suit at law or equity for any matter governed by or subject to the provisions of this Agreement.

10.12    Applicable Law. This Agreement shall be governed by, and construed and interpreted in accordance with the Laws and Regulations of the State of Texas, without giving effect to any choice or conflict of law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the Laws and Regulations of any jurisdiction other than the State of Texas.

10.13    Several Obligations of Sellers. Except as provided in Section 7.2, the obligations of each Seller under or arising out of this Agreement are several and not joint. Without limiting the generality of the foregoing, any representation, warranty or covenant of a Seller contained in this Agreement (other than the representations and warranties set forth in Section 4.2) is made by such Seller only with respect to itself and its own interest in the Purchased Assets and such Seller shall not be liable for any breach (or Damages arising out of a breach) by another Seller of any of its representations, warranties or covenants contained in this Agreement (other than the representations and warranties set forth in Section 4.2).

Buyer Guarantor shall cause payment of all amounts owed by Buyer to Sellers pursuant to Article 2 hereunder if, as and when provided in this Agreement. In no event shall Buyer Guarantor have any greater liability than Buyer pursuant to this Agreement.
