Explanation of Responses:
( 1)	GIP-A Holding (CHK), L.P. ("GIP-A"), GIP-B Holding (CHK), L.P. ("GIP-B"), GIP-C Holding (CHK), L.P. ("GIP-C" and together with GIP-A and GIP-B, the "GIP Partnerships") hold 50% limited partnership interest of the Issuer. The Reporting Person is a director of the Issuer's general partner, Chesapeake Midstream GP, L.L.C. The Reporting Person is also a member of the investment committee and other internal committees of Global Infrastructure Management, LLC, which committees (among other things) have the right to vote, or direct to vote, and to dispose, or to direct the disposition of, the securities held by the GIP Partnerships. However, the Reporting Person cannot individually control the outcome of such decisions. (Continued in footnote 2).
( 2)	Additionally, the Reporting Person is a partner of an affiliate of the GIP Partnerships, and as such has a pecuniary interest in certain of the securities held by the GIP Partnerships. The Reporting Person disclaims beneficial ownership of the securities held by the GIP Partnerships in excess of his pecuniary interest in such units.
( 3)	Pursuant to a Contribution, Conveyance and Assumption Agreement, which the GIP Partnerships, the Issuer and the other parties thereto entered into prior to the time the Securities and Exchange Commission declared the Issuer's Registration Statement on Form S-1 (Registration No. 333-164905) (the "Registration Statement") effective, the GIP Partnerships will exchange their existing ownership interests in an affiliate of the Issuer for approximately 20,725,561 Common Units and 34,538,061 Subordinated Units upon the closing of the Issuer's initial public offering, and up to an additional 3,187,500 Common Units in the event the underwriter's over-allotment option is not exercised, and the Issuer will redeem for nominal consideration the current 50% limited partnership interest in the Issuer held by the GIP Partnerships. (Continued in footnote 4).
( 4)	If the Issuer increases or decreases the number of common units to be sold to the public through the underwriters, the Issuer will correspondingly decrease or increase the number of common units to be issued to the GIP Partnerships, respectively.
( 5)	The Subordinated Units will convert into Common Units on a one-for-one basis at the end of the subordination period described in the Registration Statement.
