Trustee, notice of which shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

Adjustment to the Purchase Price.

that is thirty (30) days following receipt thereof by Buyer unless Buyer gives written notice of its disagreement with the revised Closing Statement (“Notice of Disagreement”) to Seller prior to such date. Any Notice of
Disagreement shall specify in detail the dollar amount, nature, and basis of any disagreement so asserted. If a Notice of Disagreement is received by Seller in a timely manner, then the Closing Statement (as revised in accordance with paragraph

binding resolution. The Closing Statement Arbitrator shall be the accounting firm of KPMG LLP, or if unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by Buyer and Seller in

submit a brief to the Closing Statement Arbitrator with dollar figures for settlement of the disputes as to the amount of the Adjusted Purchase Price (together with a proposed Closing Statement that reflects such figures) consistent with their
respective calculations delivered pursuant to Section 3.3(a). The hearing will be scheduled seven (7) days following submission of the settlement briefs, or as soon thereafter as is acceptable to the Closing Statement Arbitrator,
and shall be conducted on a confidential basis. The Closing Statement Arbitrator shall consider only those items or amounts in the Closing Statement as to which the Parties disagreed and render a decision resolving the matters in dispute (which
decision shall include a written statement of findings and conclusions) promptly after the conclusion of the hearing, unless the Parties reach agreement prior thereto and withdraw the dispute from arbitration. The Closing Statement Arbitrator shall
provide to the Parties explanations in writing of the reasons for its decisions regarding the Adjusted Purchase Price and shall issue the Final Closing Statement reflecting such decision. The decision of the Closing Statement Arbitrator shall be
final and binding on the Parties. The cost of any arbitration (including the fees and expenses of the Closing Statement Arbitrator) under this Section 3.3(b) shall be borne equally by Buyer and Seller. The fees and disbursements of
Seller’ independent auditors incurred in connection with the services performed with respect to the Closing Statement shall be borne by Seller and the fees and disbursements of Buyer’s independent auditors incurred in connection with their
preparation of the Notice of Disagreement shall be borne by Buyer. As used in this Agreement, the term “Final Closing Statement” shall mean the revised Closing Statement described in Section 3.3(a), as prepared by Seller
and as may be subsequently adjusted to reflect any subsequent written agreement between the Parties with respect thereto, or if submitted to the Closing Statement Arbitrator, the Arbitrator’s Closing Statement (“Arbitrator’s
Closing Statement”) as described in this Section 3.3(b). 
 (c) Final Settlement. If
the amount of the Adjusted Purchase Price as set forth on the Final Closing Statement exceeds the amount of the Estimated Adjusted Purchase Price, then Buyer shall pay to Seller, within five (5) Business Days after the Final Settlement Date,
the amount by which the Adjusted Purchase Price as set forth on the Final Closing Statement exceeds the amount of the Estimated Adjusted Purchase Price, together with interest at the Agreed Rate on such excess amount from the Closing Date until
paid. If the amount of the Adjusted Purchase Price as set forth on the Final Closing Statement is less than the amount of the Estimated Adjusted Purchase Price, then Seller shall pay to Buyer, within five (5) Business Days after the Final
Settlement Date, the amount by which the Adjusted Purchase Price, as set forth on the Final Closing Statement, is less than the amount of the Estimated Adjusted Purchase Price, together with interest at the Agreed Rate on such deficiency amount from
the Closing Date until paid. Any post-Closing payment made pursuant to this Section 3.3(c) shall be made by means of a wire transfer of immediately available funds to a bank account designated by the Party receiving the funds.

liabilities of Seller to the extent that they are attributable to or arise out of the Excluded Assets (the “Assumed Obligations”).

Sale Agreement

 Page 27 

 Section 9.2 Indemnification by Buyer. From and after the Closing Date,
Buyer shall indemnify and hold harmless Seller, its Affiliates, and each of their directors, officers, employees, representatives, agents, successors, and assigns (collectively, the “Seller Indemnified Parties”) from and against any
and all Losses incurred by any of the Seller Indemnified Parties arising out of (i) any breach of Buyer’s representations or warranties made in this Agreement, (ii) any breach of the covenants or obligations made or to be performed by
Buyer under this Agreement, or (iii) the Assumed Obligations. 
 Section 9.3 Indemnification by Seller.
From and after the Closing Date, Seller shall indemnify and hold harmless Buyer and its directors, officers, employees, representatives, agents, successors, and assigns (collectively, the “Buyer Indemnified Parties”) from and
against any and all Losses incurred by any of the Buyer Indemnified Parties arising out of (i) any breach of Seller’s representations or warranties made in this Agreement, (ii) any breach of the covenants or obligations made or to be
performed by Seller and its Affiliates under this Agreement, and (iii) the Excluded Assets. 
 Section 9.4
Indemnity Limitations. 
 (a) Cap; Threshold. Seller’s aggregate liability to the Buyer Indemnified Parties under
Section 9.3(i) shall not exceed ten percent (10%) of the Purchase Price, except for Seller’s representations and warranties in Sections 4.1(a), (b), (c), (d), (m) and (n)(i), which
shall not be subject to such limit. No claim (other than a claim based on a breach of Sections 4.1(a), (b), (c), (d), (m) and (n)(i)) may be made against Seller for indemnification under
Section 9.3(i) with respect to any individual item (or group of related items) of Loss unless such Loss exceeds $50,000 (nor shall any such Loss below such threshold be applied to or considered for purposes of calculating Seller’s
aggregate liability to the Buyer Indemnified Parties). 
 (b) Survival Period. The representations and warranties of
Seller in Section 4.1 shall survive the Closing until December 31, 2012, except for Seller’s representations and warranties in Sections 4.1(a), (b), (c), (d), (m) and (n)(i), which
shall survive the Closing until thirty (30) days following the expiration of the applicable statute of limitations. The representations and warranties of Buyer in Section 4.2 shall survive the Closing until thirty (30) days
following the expiration of the applicable statute of limitations. The covenants and agreements of the Parties in this Agreement shall survive the Closing in accordance with their terms. Notwithstanding the foregoing, any assertion by any Buyer
Indemnified Party under Section 9.3(i) for any claim (other than a claim based on a breach of Sections 4.1(a), (b), (c), (d), (m) and (n)(i)) must be made in a notice delivered to Seller in
accordance with Section 12.6 (or not at all) within one hundred eighty (180) days following the Closing Date. 

(c) Knowledge. Buyer shall not be entitled to assert the breach of any representation or warranty of Seller in
Section 4.1 as a basis for a claim for indemnification under Section 9.3(i) if Seller can demonstrate (i) that Buyer had actual knowledge of such alleged breach prior to Closing and (ii) that Buyer failed to provide
written notice (including reasonable details) to Seller of such alleged breach prior to Closing.

 Section 9.5 Third Party Claims. If a claim by a third party a
(“Third Party Claim”) is made against a Seller Indemnified Party or a Buyer Indemnified Party (an “Indemnified Party”), and if such party intends to seek indemnity with respect thereto under Article 9 or
Section 9.3, such Indemnified Party shall promptly furnish written notice to the indemnifying party (the “Indemnitor”) of such claims. The Indemnitor shall have thirty (30) days after receipt of such notice to
undertake, conduct, and control (through counsel of its own choosing and at its own expense) the defense thereof. The Indemnitor may not assume control of the defense of any Third Party Claim if (i) the Third Party Claim relates to or arises in
connection with any criminal liability, (ii) the Third Party Claim seeks an injunction or equitable relief against the Indemnified Party, or (iii) the Indemnified Party reasonably believes an adverse determination with respect to the Third
Party Claim would be materially detrimental to the Indemnified Party’s reputation or future business prospects, but in any event, shall remain subject to its indemnification obligations in this Article 9. If the Indemnitor elects to
undertake the defense of any Third Party Claim, the Indemnified Party shall cooperate with it in connection therewith; provided that the Indemnitor shall not settle any such Third Party Claim without the prior written consent of the Indemnified
Party (which consent will not be unreasonably withheld or delayed) unless the relief consists solely of money damages and includes a provision whereby the plaintiff or claimant in the matter releases Buyer Indemnified Parties or Seller Indemnified
Parties, as applicable, from all liability with respect thereto. The Indemnitor shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party (however, the fees and expenses of such
counsel shall be borne by such Indemnified Party except if (i) the Indemnified Party shall have determined in good faith that an actual or potential conflict of interest makes representation by the same counsel or the counsel selected by the
Indemnitor inappropriate or (ii) the Indemnitor shall have authorized the Indemnified Party to employ separate legal counsel at the Indemnitor’s expense). So long as the Indemnitor, at Indemnitor’s cost and expense, (i) has
undertaken the defense of, and assumed full responsibility for all indemnified liabilities with respect to, such claim, (ii) is reasonably contesting such claim in good faith, by appropriate proceedings, and (iii) has taken such action
(including the posting of a bond, deposit, or other security) as may be necessary to prevent any action to foreclose a lien against or attachment of the property of the Indemnified Party for payment of such claim, the Indemnified Party shall not pay
or settle any such claim. Notwithstanding compliance by the Indemnitor with the preceding sentence, the Indemnified Party shall have the right to pay or settle any such claim, provided that in such event it shall waive any right to indemnity
therefor by the Indemnitor for such claim. If within thirty (30) days after the receipt of the Indemnified Party’s notice of a claim of indemnity hereunder, the Indemnitor does not notify the Indemnified Party that it elects (at
Indemnitor’s cost and expense) to undertake the defense thereof and assume full responsibility for all indemnified liabilities with respect thereto, or gives such notice and thereafter fails to contest such claim in good faith or to prevent
action to foreclose a lien against or attachment of the Indemnified Party’s property as contemplated above, the Indemnified Party shall have the right to contest but shall not settle or compromise the claim and, to the extent the actions taken
by the Indemnified Party in settling or compromising such claim are reasonable and in good faith, the Indemnified Party shall not thereby waive any right to indemnity therefor pursuant to this Agreement. 

Section 9.6 Purchase Price Adjustment. Any amount paid by Seller or Buyer under Article 9 will be treated as an
adjustment to the Adjusted Purchase Price unless a determination within the meaning of Code Section 1313(a) or change in applicable law causes any such amount not to constitute an adjustment to the Adjusted Purchase Price for Tax purposes.

Sale Agreement

 Section 9.7 No Consequential
Damages. Neither Party shall be liable to the other Party for any consequential, indirect, punitive, exemplary, and special damages under this Agreement, except this waiver shall not apply to the extent such
consequential, indirect, punitive, exemplary, or special damages are asserted by a third party against an Indemnified Party. 
 Section 9.8 Disclaimers. The Assets are being conveyed and assigned to and accepted by Buyer in their “as is, where is” condition and state of repair, and
with all faults and defects, without, except as provided in this Agreement, any representation, warranty, or covenant of any kind or nature, express, implied, or statutory, including warranties of marketability, quality, condition, conformity to
models (financial or otherwise) or samples, accuracy of data, merchantability, or fitness for a particular purpose, all of which are expressly disclaimed by Seller and waived by Buyer. Seller disclaims all liability and responsibility for any
representation, warranty, statement or information orally or in writing made or communicated to Buyer or its representatives including any opinion, information or advice which may have been provided to Buyer or its representatives by Seller,
including (a) any models provided by Seller, which have been provided for illustration purposes only, (b) any correspondence from or presentation by Seller, and (c) any information or statements made available to Buyer or its
representatives during site or office visits, in any data room or in any presentation. 
 Except as expressly
represented otherwise in Section 4.1(l), Seller has not and will not make any representation or warranty regarding any matter or circumstance relating to Environmental Laws, Environmental Liabilities, the release of materials into the
environment or the protection of human health, safety, natural resources or the environment, or any other environmental condition of the Assets, and nothing in this Agreement or otherwise shall be construed as such a representation or warranty, and
Buyer shall be deemed to be taking the Assets “as is, where is” for purposes of their environmental condition. 

Article 10 

Termination And Remedies 
 Section 10.1 Termination. 
 (a) Termination
of Agreement. This Agreement and the transactions contemplated hereby may be terminated at any time prior to the Closing: 
 (i) by either Buyer or Seller, as provided in Section 12.3; 
 (ii) by the mutual written consent of Seller and Buyer; or 
 (iii)
if the Closing has not occurred by the close of business on December 30, 2011, then (a) by Seller if any condition specified in Section 7.1 has not been satisfied on or before such close of business, and shall not theretofore
have been waived by Seller, or (b) by Buyer if any condition specified in Section 7.2 has not been satisfied on or before such close of business, and shall not theretofore have been waived by Buyer; provided, in each case, that the
failure to consummate the transactions contemplated hereby on or before such date did not result from the failure by the Party seeking termination of this Agreement to fulfill any undertaking or commitment provided for herein on the part of such
Party that is required to be fulfilled on or prior to Closing. 

  
 Purchase and
Sale Agreement 
 15 November 2011 
 Page 30 

 (b) Effect of Termination. In the event of termination of this
Agreement by Seller or Buyer under Section 10.1(a), written notice thereof shall forthwith be given by the terminating Party to the other Party, and this Agreement shall thereupon terminate. Following such termination, the provisions of
Section 5.2, Section 9.7, and Section 12.5 shall survive any termination hereof under this Section 10.1(b). If this Agreement is terminated as provided herein (i) all filings, applications, and
other submissions made to any Governmental Authority shall, to the extent practicable, be withdrawn from the Governmental Authority to which they were made, and (ii) such termination shall be without liability of either Party (or any
stockholder, director, officer, employee, agent, consultant or representative of such Party) to the other Party; provided that if such termination shall result from the (A) willful failure of either Party to fulfill a condition to the
performance of the obligation of the other Party, (B) failure to perform a covenant of this Agreement, or (C) breach by either Party of any representation or warranty or agreement contained herein, such Party shall be fully liable for all
and any damages incurred or suffered by the other Party a result of such failure or breach. 
 Article 11 

Taxes 

Section 11.1 Allocation of Taxes. 

(a) Transfer Taxes. Transfer Taxes incurred in connection with the transactions contemplated by this Agreement
shall be borne equally by Seller and by Buyer. 
 (b) Property Taxes. Property Taxes for calendar year
2011 shall be prorated between Seller and Buyer (with Seller liable for the Property Taxes for the portion of the tax period prior to the Effective Date). Buyer shall pay or cause to be paid to the Operator all Property Taxes relating to calendar
year 2011. If Seller’s pro-rata portion of the Property Taxes exceeds the amount by which the Purchase Price was reduced under Section 3.1(iv), Seller shall pay to Buyer such excess no later than thirty (30) days after receipt
of Buyer’s statement. If the amount by which the Purchase Price was reduced under Section 3.1(iv) exceeds Seller’s pro rata portion of the Property Taxes, Buyer shall pay Seller such excess at the time Buyer delivers its
statement to Seller. 
 (c) Allocation of Other Taxes. Except as set forth in Section 11.1(a)
and (b), Seller shall be responsible for all Taxes imposed on or with respect to the Assets that are attributable to any whole or partial taxable period before the Effective Date and Buyer shall be responsible for all other Taxes imposed on
or with respect to the Assets. 
 (d) Interim Closing. To the extent allowable under the C&O
Agreement, all items of income, gain, loss, deduction, and credit of the Tax Partnership attributable to the Assets for the taxable year of the Tax Partnership that includes the Effective Date shall be allocated between Buyer and Seller under the
interim closing of the books method in accordance with Treas. Reg. § 1.706-1(c)(2).

 Section 11.2 Cooperation. Buyer and Seller will cooperate with each other
and with each other’s respective agents, including accounting firms and legal counsel, in connection with the preparation or audit of any Tax Return or report and any Tax claim or litigation in respect of the Assets that include whole or
partial taxable periods, activities, operations, or events on or prior to the Effective Date, which cooperation shall include, but not be limited to, making available employees, if any, or original documents, or either or both of them, for the
purpose of providing testimony and advice (the cost of which shall be borne by the requesting Party). In the event of a contest with a Tax authority regarding Taxes relating to the Assets for which Seller is wholly responsible hereunder, Seller
shall have the right to control the contest; provided, however that Seller shall not settle any such contest in a manner that would adversely affect the Assets or Buyer for any tax period after the Effective Date without Buyer’s consent. In a
contest with a Tax authority regarding Taxes related to the Assets for which Seller and Buyer are jointly responsible hereunder, Seller and Buyer shall jointly control the contest in good faith with each other. Reasonable out-of-pocket expenses with
respect to such contests shall be borne by the Parties pro-rata in accordance with their responsibility for such Taxes as set forth in this Agreement. 
 Section 11.3 Section 754 Election. Seller will use commercially reasonable efforts to obtain any consent required for the Tax Partnership to make an election pursuant to
Section 754 of the Code effective for the taxable year that includes the Closing Date.

or more counterparts have been signed by each of the Parties and delivered to the other Party. 
 Section 12.2
Governing Law. This Agreement and the respective rights and obligations of the Parties shall be governed by, interpreted, and enforced in accordance with the Laws of the State of Texas. 

Section 12.3 Casualty Loss Prior to Closing. 

(a) Non-Material Casualty. If, prior to Closing, any part of the Assets is damaged or destroyed by fire, flood,
storm, or other casualty (a “Casualty”), if in Buyer’s reasonable good faith estimation the amount of aggregate damages caused by one or more Casualties to the Burns Point Gas Plant does not exceed $1,000,000 net to the
interest of Seller (the “Casualty Threshold”), Buyer shall proceed to purchase the Assets, and unless the Casualty is repaired prior to Closing, the Purchase Price shall be reduced by Seller’s share of the repair or replacement
cost thereof, as applicable, of the damaged or destroyed assets. 

  
 Purchase and
Sale Agreement 
 15 November 2011 
 Page 32 

 (b) Material Casualty. If, prior to Closing, any part of Burns Point
Gas Plant is damaged or destroyed by a Casualty and the amount of aggregate damages caused by one or more Casualties exceeds the Casualty Threshold, Seller shall promptly notify Buyer of such Casualty. Each of Buyer and Seller will then have a right
to terminate this Agreement by written notice to the other Party. If neither Party elects to so terminate this Agreement, Buyer shall proceed to purchase the Assets, and the Purchase Price shall be reduced by Seller’s share of the repair cost
or replacement cost, as applicable, of such damaged or destroyed assets.

 Section 12.8 Amendments and Waivers. This Agreement may not be modified
or amended except by an instrument or instruments in writing signed by the Party against whom enforcement of any such modification or amendment is sought. Any Party may, only by an instrument in writing, waive compliance by another Party hereto with

lower amounts) are or are not material, and neither Party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Schedules in any dispute or controversy between the Parties as to whether any
obligation, item, or matter not described herein or included in a Schedule is or is not material for purposes of this Agreement. 
 Section 12.10 Agreement for the Parties’ Benefit Only. Except as specified in Article 9, which is also intended to benefit and to be enforceable by any of the indemnified
parties thereunder, this Agreement is not intended to confer upon any Person not a Party any rights or remedies hereunder, and no Person, other than the Parties or the indemnified parties, is entitled to rely on any representation, warranty,
covenant, or agreement contained herein. In each case, such third party beneficiary may only bring suit against the defaulting Party. 
 Section 12.11 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to any Party. Upon such
determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an
acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

 Exhibit 8.2(iii) 

Certificate of Non-Foreign Status 
 Section 1445 of the Internal Revenue Code of 1986, as amended, (the “Code”) provides that a transferee of a U.S. real property interest must withhold tax if the transferor is a foreign
person. For U.S. tax purposes (including section 1445), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property and not the disregarded entity. To inform the
transferee, American Midstream Partners, LP (“AMID” or “Transferee”) that withholding of tax is not required upon the disposition of a U.S. real property interest by the transferor, Marathon Oil Company, an Ohio Corporation
(“Marathon” or “Transferor”), the undersigned hereby certifies the following on behalf of Marathon: 
  

	 	1.	Marathon is not a foreign corporation, foreign partnership, foreign trust, or foreign estate (as those terms are defined in the Internal Revenue Code and its
accompanying Income Tax Regulations) nor a nonresident alien for U.S. income tax purposes; 

  

	 	2.	Marathon is not a disregarded entity as defined in Treas. Reg. Section 1.1445-2(b)(2)(iii); 

 

	 	3.	Marathon’s U.S. employer identification number is 25-1410539; and 

  

	 	4.	Marathon’s office address is 5555 San Felipe Road, Houston, TX 77056 

 Transferor understands that this certification may be disclosed to the Internal Revenue Service by Transferee and that any false statement contained herein could be punished by fine, imprisonment, or
both. 
 Under penalties of perjury, I declare that I have examined this certification and to the best of my knowledge and belief it is true,
correct, and complete, and I further declare that I have authority to sign this document on behalf of Marathon. 
 In witness whereof, the
undersigned has duly executed this certificate of Non-Foreign Status as of the date written below.

Burns Point Gas Plant pursuant the Surface Lease dated July 1, 1996, but effective September 21, 1992, by and between St. Mary Land & Exploration Company and Marathon Oil Company duly recorded in the Clerk’s office of St.
Mary Parish Louisiana as Entry No. 254,745 in Conveyance Book 39-M, at Folio 530. The Operator continues to use the land and facilities in connection with operation of the Burns Point Gas Plant. The lease is past its primary term, and it
remains in the name of Marathon Oil Company. However, rental payment on the lease is current through September 2011. Therefore, to the knowledge of Seller, Operator does not have good and marketable title to, or a valid and enforceable leasehold
interest in, the real property used for the metering station and interconnection facilities.
