Remarks:

(A) ArcLight Capital Holdings, LLC ("ArcLight") is the sole manager and member of ArcLight Capital Partners, LLC ("ArcLight Partners" and, together with ArcLight Holdings and ArcLight Energy Partners Fund V, L.P. ("Fund V"), the "ArcLight Entities"). ArcLight Partners is the investment adviser to Fund V. ArcLight Holdings is the manager of the general partner of Fund V. Mr. Revers is a manager of ArcLight Holdings, and a managing partner of ArcLight Partners and has certain voting and dispositive rights as a member of ArcLight Partners' investment committee. Fund V directly owns Busbar II, LLC ("Busbar") and Magnolia Holdings, which owns Magnolia. Fund V, through Magnolia, also owns approximately 90% of the ownership interest in HPIP. HPIP and AMID GP Holdings LLC, a subsidiary of Magnolia Holdings, own respectively, approximately 77% and 23% of American Midstream GP, LLC (the "General Partner"), the general partner of the Issuer. As a result, the ArcLight Entities and Mr. Revers may be deemed to indirectly beneficially own the securities of the Issuer held by Magnolia Holdings, Busbar, Magnolia, HPIP and the General Partner, but disclaim beneficial ownership except to the extent of their respective pecuniary interests therein.
