The provisions of this Section 4 shall cease and be of no further force or effect upon the Termination of this Agreement.

5. Termination

     5.1 This Agreement shall terminate (“Termination”) upon the occurrence of any of the following (provided that no such termination shall relieve any party from liability for its breach or non-performance of its obligations hereunder prior to the date of such termination):

Any time period relating to the Corporate Restructuring Transactions under the Existing Credit Agreements shall begin to run anew as of the date of such Termination as if such Corporate Restructuring Transactions had not been consummated; and the PostRock Parties shall be entitled to cure any such Default or Event of Default by unwinding some or all of the Corporate Restructuring Transactions within such forty-five (45) day period, or by giving timely notice to, or obtaining consent from, one of more of (or, as applicable, the required percentage of) the First Lien Agent, the Second Lien Agent, the Bluestem Agent, the Holdco Agent, the First Lien Lenders, the Second Lien Lenders, the Bluestem Lenders, and the Holdco Lender with respect to the Corporate Restructuring Transactions, to the extent required by and pursuant to the terms of the Existing Credit Agreements.
