Exhibit 10.1

THIS WARRANT HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE (THE “STATE LAWS”).  THIS WARRANT MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED OR OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, IN THE ABSENCE OF SUCH REGISTRATION OR QUALIFICATION OR THE AVAILABILITY OF AN APPLICABLE EXEMPTION FROM THE REGISTRATION AND QUALIFICATION REQUIREMENTS OF SUCH ACT AND STATE LAWS EVIDENCED BY AN OPINION OF LEGAL COUNSEL, WHICH OPINION AND LEGAL COUNSEL ARE SATISFACTORY TO THE PARTNERSHIP.

WARRANT TO PURCHASE COMMON UNITS OF

AMERICAN MIDSTREAM PARTNERS, LP

This Warrant certifies that, for value received, AIM Midstream Holdings, LLC, or its registered assigns (collectively, the “Holder”), are entitled to purchase from American Midstream Partners, LP, a Delaware limited partnership (the “Partnership”), up to 300,000 common units representing limited partner interests in the Partnership (the “Common Units”) for an exercise price of $0.01 per Common Unit (the “Exercise Price”). This Warrant shall be exercisable as of and from February 8, 2014 until the tenth anniversary of the date hereof.

As used herein, the term “Warrant Exercised Units” refers to the Common Units issuable upon exercise of this Warrant.  “Common Units” shall mean the common units of the Partnership, which, for the avoidance of doubt shall not include the Partnership’s Series A Preferred Units, Series B Units, or other similar units issued by the Partnership hereafter.  Terms used but not defined in this Warrant are defined in the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership dated August 9, 2013, as amended (the “Fourth A/R Partnership Agreement”).

This Warrant, together with all warrants issued upon transfer, exchange or in replacement hereof pursuant to Section 4 (collectively, the “Warrants”), is subject to the following additional terms, provisions and conditions:

Section 1.                                           Manner of Exercise; Issuance of Certificates; Payment for Warrant Exercised Units.  Subject to the provisions hereof, this Warrant (i) may be exercised by the Holder, in whole or in part, on or after the date hereof and (ii) must be exercised by the Holder, in whole, if a Series A Change of Control occurs, in each case by the surrender of this Warrant, together with a completed Exercise Agreement in the form attached hereto, to the Partnership during normal business hours on any Business Day at the Partnership’s office in Denver, Colorado (or such other office or agency of the Partnership as it may designate by notice to the Holder).  Payment of the Exercise Price shall be made by the Holder in cash, by wire transfer of immediately available funds,  by certified or official bank check or pursuant to the Conversion Right (defined below).

In lieu of the payment of the Exercise Price in cash, by wire transfer of immediately available funds,  by certified or official bank check, Holder shall have the right (but not the obligation), to require the Partnership to convert this Warrant, in whole or in part, into Common Units (the “Conversion Right”).  Upon exercise of the Conversion Right, the Partnership shall deliver to Holder (without payment by Holder of any of the Exercise Price) that number of Warrant Exercised Units equal to the number Common Units set forth on any Exercise Agreement less a number of common units equal to the quotient obtained by dividing (x) the aggregate Exercise Price for the number of Common Units set forth on the Exercise Agreement by (y) the closing trading price of one (1) Common Unit on the day immediately prior to the exercise of the Conversion Right. The Warrant Exercised Units so purchased or converted shall be deemed to be issued to the Holder or its designees as the record owner of such Common Units as of the close of business on the date or dates on which this Warrant shall have been surrendered, the completed Exercise Agreement delivered and payment (by means of wire transfer of immediately available funds,  by certified or official bank check or pursuant to the Conversion Right)  made for such Warrant Exercised Units as aforesaid.

If this Warrant has been exercised in part, the Partnership shall, at the time of delivery of the acknowledgement reflecting the ownership of the Warrant Exercised Units, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Common Units called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of Holder, appropriate notation may be made on this Warrant and the same returned to Holder.

Section 2.                                           Certain Actions Prohibited.  The Partnership will not, by amendment of the Fourth A/R Partnership Agreement or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder of this Warrant in order to protect the exercise privilege of the Holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

Section 3.                                           Anti-Dilution Provisions and Other Adjustments. The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment, from time to time, as follows:

(a)                                 Consolidation or Merger.  If, at any time while this Warrant remains outstanding and unexpired, the Partnership shall (i) consolidate or merge with any other entity (regardless of whether the Partnership is the continuing or surviving entity, except that in connection with a consolidation or merger where the Partnership is not the continuing or surviving entity, the Common Units shall be changed into or exchanged for units, stock or other securities of the surviving entity or cash or any other property), (ii) transfer all or substantially all of its properties or assets to any other person or entity or (iii) effect a capital reorganization or reclassification of the Common Units, the Partnership, or such successor entity as the case may be, shall, without payment of any additional consideration therefor, execute a new warrant providing that the Holder shall have the right to exercise such new warrant (upon terms no less favorable to the Holder than those applicable to this Warrant and immediately exercisable) and to receive upon such exercise, in lieu of each Common Unit theretofore issuable upon exercise of this Warrant, the kind and amount of units, shares of stock or other securities, money or property receivable upon such capital reorganization, reclassification, change, consolidation, merger or sale or conveyance by the holder of one Common Unit issuable upon exercise of this Warrant had it been exercised immediately prior to such capital reorganization, reclassification, change, consolidation, merger or sale or conveyance.  The provisions of this Section 3(a) shall similarly apply to successive capital reorganizations, reclassifications, changes, consolidations, mergers, sales and conveyances.

(b)                                 Dividends and Distributions in Common Units.  If the Partnership shall pay or make a dividend or other distribution on its Common Units in additional Common Units, the Exercise Price in effect at the opening of business on the day following the date fixed for the determination of unitholders entitled to receive such dividend or other distribution (the “Determination Date”) shall be reduced by multiplying such Exercise Price by a fraction, (i) the numerator of which shall be the number of Common Units outstanding as of the close of business on the Determination Date and (ii) the denominator of which shall be the sum of (x) the number of Common Units outstanding at the close of business on the Determination Date and (y) the total number of Common Units constituting such dividend or other distribution.  Such reduction shall become effective immediately after the opening of business on the day following the Determination Date.  For the purposes of this Section 3(b), the number of Common Units at any time outstanding shall not include Common Units held in the treasury of the Partnership.  The Partnership will not pay any dividend or make any distribution on Common Units held in the treasury of the Partnership.

(c)                                  Unit Splits or Combinations.  In case the outstanding Common Units shall be subdivided into a greater number of Common Units, the Exercise Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be reduced, and, conversely, in case the outstanding Common Units shall each be combined into a smaller number of Common Units, the Exercise Price in effect at the opening of business on the day following the date upon which such combination becomes effective shall be increased, in each case, to equal the product of the Exercise Price in effect on such date and a fraction, (i) the numerator of which shall be the number of Common Units outstanding immediately prior to such subdivision or combination, as applicable, and (ii) the denominator of which shall be the number of Common Units outstanding

2

immediately after such subdivision or combination, as applicable.  Such reduction or increase, as applicable, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective (the “Alteration Date”).

(d)                                 Reclassifications.  The reclassification or change of Common Units (other than any reclassification upon a consolidation or merger to which Section 3(a) shall apply) into securities, including securities other than Common Units, shall be deemed to involve (i) a distribution of such securities other than Common Units to all holders of Common Units (and the effective date of such reclassification shall be deemed to be the Determination Date within the meaning of Section 3(b)), and (ii) a subdivision or combination, as applicable, of the number of Common Units outstanding immediately prior to such reclassification into the number of Common Units outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be the Alteration Date within the meaning of Section 3(c)).

(e)                                  Adjustment of Number of Units.  Upon each adjustment in the Exercise Price pursuant to any provision of this Section 3, the number of Common Units purchasable hereunder at the Exercise Price shall be adjusted, to the nearest whole Common Unit, to the product obtained by multiplying such number of Common Units purchasable immediately prior to such adjustment in the Exercise Price by a fraction, (i) the numerator of which shall be the Exercise Price immediately prior to such adjustment and (ii) the denominator of which shall be the Exercise Price immediately thereafter.

(f)                                   Other Provisions Applicable to Adjustments Under This Section.  The following provisions will be applicable to the making of adjustments in the Exercise Price provided in this Section 3:

(i)                                     No adjustment in the Exercise Price need be made under Section 3(b) if the Partnership issues or distributes (or holds in a segregated manner pending exercise of this Warrant into Common Units and upon such exercise distributes) to the Holder the Common Units, evidences of indebtedness, assets, rights, options or warrants referred to in those paragraphs that such Holder would have been entitled to receive had this Warrant been exercised for Common Units prior to the happening of such event or the record date with respect thereto.

(ii)                                  All calculations under this Section 3 shall be made to the nearest 1/100th of a cent or to the nearest whole Common Unit, as applicable.  No adjustment in the Exercise Price shall be required unless such adjustment (plus any adjustments not previously made by reason of this Section 3(f)(ii)) would require an increase or decrease of at least 1% in such Exercise Price.

(g)                                  Notice to the Holder.  The Partnership will deliver to the Holder written notice, at the same time and in the same manner that it is required to give such notice under the Fourth A/R Partnership Agreement of any event or transaction potentially giving rise to an adjustment or modification of the terms and provisions of the Warrant Exercised Units.  The Partnership will take all steps reasonably necessary in order to insure that the Holder is able to exercise this Warrant prior to the time of such event or transaction so as to participate in or vote with respect to such event or transaction.

Section 4.                                           Transfer, Exchange and Replacement of Warrant; Representations and Covenants.

(a)                                 Warrant Transferable.  The Holder of this Warrant may transfer and assign it to any Affiliate, provided that such party is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), as presently in effect. The Holder of this Warrant may not transfer and assign it to any other person without the prior written consent of the Partnership.  The permitted or approved transfer of this Warrant and all rights hereunder, in whole or in part, is registrable at the office or agency of the Partnership referred to in Section 5 by the Holder in person or by his duly authorized attorney, upon surrender of this Warrant properly endorsed. Upon any permitted or approved transfer of this Warrant to any person, other than a person who is at that time a holder of other Warrants, the Partnership shall have the right to require the Holder and the transferee to make customary representations to the extent reasonably necessary to assure that the transfer will comply with the Securities Act and any applicable state securities laws.  The Holder of this Warrant, by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank, shall be deemed negotiable, and that the Holder, when this Warrant shall have been so endorsed, may be treated by the Partnership

3

and all other persons dealing with this Warrant as the absolute owner and holder for any purpose and as the person entitled to exercise the rights represented by this Warrant and to the registration of transfer hereof on the books of the Partnership; but until due presentment for registration of transfer on such books the Partnership may treat the registered Holder as the owner and holder of this Warrant for all purposes, and the Partnership shall not be affected by any notice to the contrary.

(b)                                 Warrant Exchangeable for Different Denominations.  This Warrant is exchangeable, upon the surrender of this Warrant by the Holder at the office or agency of the Partnership referred to in Section 5, for new warrants of like tenor representing in the aggregate the right to purchase the number of Common Units which may be purchased hereunder, each of such new warrants to be imprinted with the same legend appearing on the face of this Warrant and to represent the right to purchase such number of Common Units as shall be designated by the Holder at the time of such surrender.

(c)                                  Replacement of Warrant.  Upon receipt of evidence reasonably satisfactory to the Partnership of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Partnership, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Partnership, at its expense, will execute and deliver, in lieu thereof, a new warrant of like tenor.

(d)                                 Cancellation; Payment of Expenses.  Upon the surrender of this Warrant in connection with any transfer, exchange, or replacement as provided in Section 4(c), this Warrant shall be promptly cancelled by the Partnership.  The Partnership shall pay all taxes (other than securities transfer taxes) and all other expenses and charges payable in connection with the preparation, execution and delivery of Warrants pursuant to this Section 4.

(e)                                  Register.  The Partnership shall maintain, at its office in Denver, Colorado (or such other office or agency of the Partnership as it may designate by notice to the Holder), a register for this Warrant, in which the Partnership shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee and each prior owner of this Warrant.

(f)                                   Representations and Covenants of the Partnership.  The Partnership represents and covenants as of the date hereof and as of the date of any exercise hereof that:

1.                                      The Partnership is a limited partnership duly organized, validly existing and in good standing under the laws of the State of Delaware.

2.                                      The Warrant has been duly authorized, validly issued and is a valid and binding obligation of the Partnership, enforceable against the Partnership in accordance with the terms hereof (except as such enforceability may be limited by bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law)).

3.                                      All Warrant Exercised Units have been duly authorized and will, when issued, be validly issued, fully paid and nonassessable (except to the extent such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act).

4.                                      The issuance of the Warrant does not, and the issuance of the Warrant Exercised Units upon exercise of the Warrant will not, conflict with (i) the Partnership’s certificate of limited partnership, (ii) the Fourth A/R Partnership Agreement, (iii) any other agreement of the Partnership or (iv) any applicable laws (except in the case of clauses (iii) and (iv) for such conflict that would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the condition (financial or other), results of operations, unitholders’ equity, properties or business of the Partnership).

4

5.                                      Upon the exercise of this Warrant, the issuance of the Warrant Exercised Units will not be subject to any preemptive or similar rights, other than pursuant to Sections 5.2 and 5.8 of the Fourth A/R Partnership Agreement.

(g)                                  Representations and Covenants of the Holder.  The Holder is acquiring this Warrant and will acquire the Warrant Exercised Units for its own account, with no present intention of distributing or reselling this Warrant or the Warrant Exercised Units or any part thereof in violation of applicable securities laws.  The Holder acknowledges that this Warrant has not been, and when issued the Warrant Exercised Units will not be, registered under the Securities Act or the securities laws of any state in the United States or any other jurisdiction and may not be offered or sold by such Holder unless subsequently registered under the Securities Act (if applicable to the transaction) and any other securities laws or unless exemptions from the registration or other requirements of the Securities Act and any other securities laws are available for the transaction.  The Holder represents that it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act, as presently in effect.

Section 5.                                           Notices.  All notices, requests, and other communications required or permitted to be given or delivered hereunder to the Holder of this Warrant shall be in writing, and shall be personally delivered, or shall be sent by certified or registered mail, postage prepaid, or by delivery service with proof of delivery, and addressed to the Holder at the address shown for the Holder on the books of the Partnership, or at such other address as shall have been furnished to the Partnership by notice from the Holder.  All notices, requests, and other communications required or permitted to be given or delivered hereunder to the Partnership shall be in writing, and shall be personally delivered, or shall be sent by certified or registered mail, postage prepaid, or by delivery service with proof of delivery, and addressed to the office of the Partnership at 1400 16th Street, Suite 310, Denver, Colorado 80202, Attention: General Counsel, or at such other address as shall have been furnished to the Holder of this Warrant by notice from the Partnership.  Any such notice, request, or other communication may be sent by facsimile but shall in such case be subsequently confirmed by a writing personally delivered or sent by certified or registered mail as provided above.  All notices, requests, and other communications shall be deemed to have been given either at the time of the delivery thereof to (or the receipt by, in the case of a facsimile) the person entitled to receive such notice at the address of such person for purposes of this Section 5 or, if mailed, at the completion of the third full day following the time of such mailing thereof to such address, as the case may be.

Section 6.                                           GOVERNING LAW.  THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO ANY CHOICE OF LAW PRINCIPLES OF SUCH STATE.

Section 7.                                           Remedies.  The Partnership stipulates that the remedies at law of the Holder of this Warrant in the event of any default or threatened default by the Partnership in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific enforcement of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

Section 8.                                           Miscellaneous.

(a)                                 Amendments.  This Warrant and any provision hereof may not be changed, waived, discharged, or terminated orally, but only by an instrument in writing signed by the party (or any predecessor in interest thereof) against which enforcement of the same is sought.

(b)                                 Descriptive Headings.  The descriptive headings of the several sections of this Warrant are inserted for purposes of reference only, and shall not affect the meaning or construction of any of the provisions hereof.
