3

General Partner or CMV, or the merger or consolidation of the General Partner or sale by the General Partner of substantially all its assets, in each case to or with a Third Party, or any public offering of the General Partner or CMV. CMV shall not take any act to remove the General Partner as the general partner of the Partnership other than in connection with a transfer of the General Partner Interest (as defined in the Partnership Agreement) permitted by the Partnership Agreement.

In the event the Second Purchase Agreement is terminated by Midstream Holdings in accordance with its terms prior to the closing of the transactions contemplated thereby pursuant to (x) Section 10.01(e) thereof or (y) Section 10.01(d) thereof, each of the GIP Parties hereby agrees that, from and after the date of such termination through and including the 180th day following such termination, it shall not, and shall cause its Affiliates (other than CHKM) not to, without the prior written consent of Midstream Holdings, (i) request the inclusion of Registrable Securities in any Registration Statement filed in response to a Demand Notice initiated by CHK or its Affiliates, (ii) deliver a Demand Notice to the Partnership, or (iii) otherwise cause the Partnership to file a Registration Statement registering the resale of Common Units owned by the GIP Parties or their Affiliates.
