Explanation of Responses:	
(  1) 	Each subordinated unit will convert into one common unit at the end of the subordination period described in the Registration Statement. The subordinated units have no expiration date.	
(  2) 	On April 15, 2013, High Point acquired beneficial ownership of all of the Issuer's 5,142,857 outstanding Series A Convertible Preferred Units pursuant to the Contribution Agreement, dated as of April 15, 2013, between the Issuer and High Point. In addition, on April 15, 2013, High Point acquired beneficial ownership of all of the Issuer's 4,526,066 outstanding Subordinated Units pursuant to the Purchase Agreement, dated as of April 15, 2013, between AIM Midstream Holdings, LLC and High Point. Each of Messrs. Bergstrom, Revers, Erhard and Taylor (collectively, the "Director Reporting Persons") is a member of the board of directors of the General Partner. (continued on footnote 3)	
(  3) 	In addition, each of the Director Reporting Persons is a member of the general partner of ArcLight Energy Partners Fund V, L.P., the indirect majority owner of High Point, and therefore may be deemed a member of a group beneficially owning 10% or more of the equity of the Issuer within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended. Each of the Director Reporting Persons disclaims beneficial ownership of these securities except to the extent of the reporting person's pecuniary interest, if any, in such securities through ownership in ArcLight Energy Fund V, L.P. and this report shall not be deemed an admission that such a group exists or that the reporting person is the beneficial owner of the securities of such group for purposes of Section 16 or for any other purpose.	
(  4) 	The Series A Convertible Preferred Units are convertible in whole or in part into Common Units at any time after January 1, 2014 or, prior to that date, with the consent of the required lenders under the Issuer's credit agreement, at the reporting person's election. The number of Common Units into which a Series A Preferred Unit is convertible will be an amount equal to (i) the sum of $17.50 and all accrued and accumulated but unpaid distributions, divided by (ii) the conversion price, which is initially $17.50, subject to customary anti-dilution adjustments. The Series A Convertible Preferred Units have no expiration date.	

Remarks:
High Point Infrastructure Partners, LLC ("High Point") also owns all of the Class A membership interests, representing 90% of all membership interests, in American Midstream GP, LLC, the general partner of the Issuer (the "General Partner"). The General Partner holds a 2% general partner interest in the Issuer, as well as the incentive distribution rights. Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions as set forth in the Issuer's Registration Statement on Form S-1 (Registration No. 333-173191) (the "Registration Statement").

                               POWER OF ATTORNEY

                  For Executing Forms 3, 4 and 5 and Form 144

      The undersigned hereby constitutes and appoints each of William B. Mathews
and Mary J. Janiszewski, signing singly, the undersigned's true and lawful
attorney-in-fact to:

      (1) execute for and on behalf of the undersigned (a) Forms 3, 4 and 5
(including amendments thereto) in accordance with Section 16(a) of the
Securities Exchange Act of 1934, as amended (the "Act") and the rules thereunder
and (b) Form 144;

      (2) do and perform any and all acts for and on behalf of the undersigned
that may be necessary or desirable to complete and execute any such Form 3, 4 or
5 or Form 144 and timely file such Forms or Schedules with the Securities and
Exchange Commission (the "SEC") and any stock exchange, self-regulatory
association or any other authority;

      (3) take any necessary or appropriate action to obtain or regenerate
codes and passwords enabling the undersigned to make electronic filings with the
SEC of reports required by Section 16(a) of the Act or any rule or regulation of
the SEC; and

      (4) take any other action of any type whatsoever in connection with the
foregoing that, in the opinion of each such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required of the undersigned, it being
understood that the documents executed by the attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as the attorney-in-fact may approve in the
attorney-in-fact's discretion.

      The undersigned hereby grants to each attorney-in-fact full power and
authority to do and perform each and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that the attorneys-in-fact substitute, shall
lawfully do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted. The undersigned acknowledges that the
foregoing attorneys-in-fact, and their substitutes, in serving in such capacity
at the request of the undersigned, are not assuming (nor is American Midstream
GP, LLC or American Midstream Partners, LP assuming) any of the undersigned's
responsibilities to comply with Section 16 of the Act.

      The undersigned agrees that each such attorney-in-fact may rely entirely
on information furnished orally, electronically or in writing by the undersigned
to the attorney-in-fact. The undersigned also agrees to indemnify and hold
harmless American Midstream GP, LLC, American Midstream Partners, LP and each
such attorney-in-fact against any losses, claims, damages or liabilities (or
actions in these respects) that arise out of or are based upon any untrue
statements or omissions of necessary facts in the information provided by the
undersigned to such attorney-in-fact for purposes of executing, acknowledging,
delivering or filing Form 3, 4 or 5 or Form 144 (including amendments thereto)
and agrees to reimburse American Midstream GP, LLC, American Midstream Partners,
LP and the attorney-in-fact on demand for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.

      This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 and Form 144
(including amendments thereto) with respect to the undersigned's holdings of and
transactions in securities issued by American Midstream Partners, LP unless
earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact; provided, however, that this Power of Attorney
shall automatically terminate with respect to any attorney-in-fact (but not with
respect to the other attorneys-in-fact) at such time as such attorney-in-fact
ceases to be an employee of American Midstream GP, LLC or any of its affiliates.
This Power of Attorney does not revoke any other power of attorney that the
undersigned has previously granted.

      IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of the date written below.
