PART III

NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As disclosed in the Current Report on Form 8-K filed with the SEC on March 17, 2015 by Quicksilver Resources Inc. (the “Company”), on March 17, 2015 the Company and its subsidiaries, Barnett Shale Operating LLC, Cowtown Drilling, Inc., Cowtown Gas Processing L.P., Cowtown Pipeline Funding, Inc., Cowtown Pipeline L.P., Cowtown Pipeline Management, Inc., Makarios Resources International Holdings LLC, Makarios Resources International Inc., QPP Holdings LLC, QPP Parent LLC, Quicksilver Production Partners GP LLC, Quicksilver Production Partners LP, and Silver Stream Pipeline Company LLC (collectively with the Company, the “Debtors”) each filed a voluntary petition for relief under chapter 11 of title 11 of the U.S. Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware to restructure their obligations and capital structure. The Debtors are currently operating their business as debtors in possession in accordance with the applicable provisions of the Bankruptcy Code.

The Company is unable to file its Quarterly Report on Form 10-Q for the period ended March 31, 2015 (the “Form 10-Q”), with the SEC within the prescribed period without unreasonable effort or expense. The Company’s management and external advisors have devoted substantial attention to the Company’s reorganization efforts. As a result of the increased burdens on the Company’s financial, accounting and administrative staff, the Company has not completed its preparation of the financial statements for the period ended March 31, 2015 that are required to be included in the Form 10-Q.

The Company expects to file the Form 10-Q no later than the fifth calendar day following the prescribed due date as set forth in Rule 12b-25.
