(c) LCP LP is a private investment vehicle that focuses on investing directly in master limited partnership-qualifying businesses and assets.

LCP GP is the general partner of LCP LP. LCP GP owns 100% of the limited liability company interests in Arc Logistics GP LLC, the general partner of the Issuer (the “General Partner”). Information with respect to the managers and Series A Members of LCP GP, including, as applicable, name, principal business, residence or business address, present principal occupation or employment, the name, principal business and address of any corporation or other organization in which such employment is conducted, citizenship and state or other place of organization, is listed on the attached Schedule A, which is incorporated in this Schedule 13D by reference.

(d), (e) During the last five years, none of the Reporting Persons nor, to the knowledge of LCP GP, any manager or Series A Member of LCP GP, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

In connection with the Issuer’s initial public offering, and pursuant to the Contribution Agreement dated October 25, 2013 by and among the Issuer, the General Partner, LCP LP, Center Terminal Company-Cleveland, Gulf Coast Asphalt Company, L.L.C., Arc Terminals GP LLC (“Arc Terminals GP”), Arc Terminals LP (“Arc Terminals”), Arc Terminals Holdings LLC and Arc Terminals Mississippi Holdings LLC, LCP LP contributed all of its limited partner interests in Arc Terminals and all of its limited liability company interests in Arc Terminals GP to the Issuer in exchange for 68,617 Common Units and 5,146,264 subordinated units representing limited partner interests (“Subordinated Units”) of the Issuer.

On November 16, 2016, the Subordinated Units converted into Common Units on a one-for-one basis upon the satisfaction of certain tests set forth in the Issuer’s First Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”).

The acquisitions of Common Units by the Reporting Persons were undertaken for investment purposes. LCP GP owns a 100% limited liability company interest in the General Partner.

(a) The Reporting Persons and the managers and Series A Members of LCP GP intend to review their investment in the Issuer, if any, on a continuing basis and, depending upon the price of and other market conditions relating to the Common Units or other securities of the Issuer, subsequent developments affecting the Issuer, the Issuer’s business and prospects, other investment and business opportunities available to the Reporting Persons and the managers and Series A Members of LCP GP, general stock market and economic conditions, tax considerations, and other factors deemed relevant, may decide to increase or decrease the size of their investment in the Issuer.
