Grant of Phantom Units. American Midstream GP, LLC (the "Company"), general partner of American Midstream Partners, LP (the "Partnership") hereby grants to you, Eric Kalamaras, 40,000 Phantom Units under the American Midstream GP, LLC Long-Term Incentive Plan (the "Plan") on the terms and conditions set forth herein and in the Plan, which is incorporated herein by reference as a part of this Agreement ("Agreement" or "Grant Agreement"). In the event of any conflict between the terms of this Agreement and the Plan, the Plan shall control. Capitalized terms used in this Agreement but not defined herein shall have the meanings ascribed to such terms in the Plan, unless the context requires otherwise.

Vesting. Except as otherwise provided in Paragraph 3 below, the Phantom Units granted hereunder shall vest on the dates as described below:

Death or Disability. If your employment with the Company terminates as a result of your death or Total and Permanent Disability, the unvested Phantom Units then held by you automatically will become fully vested upon such termination. For purposes of this Agreement, your "Total and Permanent Disability" means that you are qualified for long-term disability benefits under the Company's long-term disability plan or insurance policy; or, if no such plan or policy is then in existence or you are not eligible to participate in such plan or policy, that you, because of a physical or mental condition resulting from bodily injury, disease, or mental disorder, are unable to perform your duties of employment for a period of six (6) continuous months, as determined in good faith by the Committee.

Other Terminations. If your employment with the Company terminates for any reason other than as provided in Paragraph 3(a) above, all unvested Phantom Units then held by you automatically shall be forfeited without payment upon such termination.

Payment. If vesting of a Phantom Unit shall occur pursuant to Paragraph 2 or 3(a), above, then as soon as administratively practicable after the vesting of such Phantom Unit, but not later than seven days thereafter, you shall be paid a lump sum payment in Units equal to the number of vested Phantom Units. Notwithstanding the foregoing, however, the Committee

Limitations Upon Transfer. All rights under this Agreement shall belong to you alone and may not be transferred, assigned, pledged, or hypothecated by you in any way (whether by operation of law or otherwise), other than by will or the laws of descent and distribution and shall not be subject to execution, attachment, or similar process. Upon any attempt by you to transfer, assign, pledge, hypothecate, or otherwise dispose of such rights contrary to the provisions in this Agreement or the Plan, or upon the levy of any attachment or similar process upon such rights, such rights shall immediately become null and void.

Restrictions. By accepting this grant, you agree that any Units that you may acquire upon payment of this Award will not be sold or otherwise disposed of in any manner that would constitute a violation of any applicable federal or state securities laws. You also agree that (i) any certificates representing the Units acquired under this Award may bear such legend or legends as the Committee deems appropriate in order to assure compliance with applicable securities laws and any restrictions set forth in this Agreement, (ii) the Company may refuse to register the transfer of the Units to be acquired under this Award on the transfer records of the Partnership if such proposed transfer would in the opinion of counsel satisfactory to the Partnership constitute a violation of any applicable securities law, and (iii) the Partnership may give related instructions to its transfer agent, if any, to stop registration of the transfer of the Units to be acquired under this Award.

Withholding of Taxes. To the extent that the grant, vesting or payment of a Phantom Unit results in the receipt of compensation by you with respect to which the Company or an Affiliate has a tax withholding obligation pursuant to applicable law, unless other arrangements have been made by you that are acceptable to the Company or such Affiliate, you shall deliver to the Company or the Affiliate such amount of money as the Company or the Affiliate may require to meet its withholding obligations under such applicable law. If you fail to do so, the Company is authorized to withhold from any cash or Unit remuneration (including withholding any Units to be distributed to you under this Agreement) then or thereafter payable to you any tax required to be withheld by reason of such resulting compensation income. No payment of a vested Phantom Unit shall be made pursuant to this Agreement until you have paid or made arrangements approved by the Company or the Affiliate to satisfy in full the applicable tax withholding requirements of the Company or Affiliate with respect to such event. You may request that the Committee settle in cash, rather than in Units, a portion of any vested and payable Phantom Units to provide for the satisfaction of any tax withholding obligation resulting from such Phantom Units, and the Committee will determine the approval or the Company's performance of such request on a case by case basis.

Rights as Unitholder. Phantom Units awarded under the Plan do not have voting nor consent rights. You, or your executor, administrator, heirs, or legatees shall have the right to vote and receive distributions on Units and all the other privileges of a unitholder of the Partnership only from the date of issuance of a Unit certificate in your name representing payment of a vested Phantom Unit.

Insider Trading Policy. The terms of the Company's Insider Trading Policy with respect to Units are incorporated herein by reference. The timing of delivery of any Units pursuant to a vested Phantom Unit shall be subject to and comply with such Policy.

Binding Effect. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and upon any person lawfully claiming under you.

Entire Agreement. This Agreement and the Plan constitute the entire agreement of the parties with regard to the subject matter hereof, and contains all the covenants, promises, representations, warranties and agreements between the parties with respect to the Award granted hereby.

Modifications. Except as provided below, any modification of this Agreement shall be effective only if it is in writing and signed by both you and an authorized officer of the Company.

Governing Law. This grant shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to conflicts of laws principles thereof.
