Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On March 26, 2013, Summit Midstream Partners, LLC ("Summit") contributed the common and subordinated units reported herein to the Reporting Person in exchange for a continuing 100% interest in the Reporting Person. Summit is the sole member of the Reporting Person and as such, may be deemed to continue to have beneficial ownership of the common and subordinated units reported herein, with the only change being in the form of ownership from direct to indirect.
(2) In connection with the aforementioned transfer of units, Summit also transferred its 2% general partnership interest in the Issuer to the Reporting Person. Accordingly, the Reporting Person may be deemed to indirectly beneficially own the securities of the Issuer held by the general partner of the Issuer, but disclaims beneficial ownership except to the extent of its pecuniary interest therein. As sole owner of the general partner, the Reporting Person has the right to appoint the entire board of directors of our general partner, which together with the executive officers of the general partner manage and operate the Issuer.
(3) Each subordinated unit will convert into one common unit at the end of the subordination period described in the Issuer's Registration Statement on Form S-1 (Registration No. 333-183466).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, See Instruction 6 for procedure.
