Explanation of Responses:
( 1)	This form is jointly filed by Chesapeake Energy Corporation ("Chesapeake") and Chesapeake Midstream Holdings, L.L.C. ("Midstream Holdings").
( 2)	As of July 28, 2010, Midstream Holdings indirectly owned, through Midstream Ventures, 50% of the limited partner interest in Chesapeake Midstream Partners, L.P. (the "Partnership") and 50% of the limited liability company interest in Chesapeake Midstream GP, L.L.C., the general partner of the Partnership. Other than Chesapeake Midstream Ventures, L.L.C., all other reporting persons' ownership was indirect through Midstream Holdings.
( 3)	Pursuant to a Contribution, Conveyance and Assumption Agreement, which Midstream Holdings, 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, Midstream Holdings will exchange its existing ownership interests in an affiliate of the Issuer for (i) approximately 23,913,061 Common Units and 34,538,061 Subordinated Units upon the closing of the Issuer's initial public offering. 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 Midstream Holdings, respectively.
( 4)	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.
