QUICKSILVER RESOURCES INC. SECOND AMENDED AND RESTATED KEY EMPLOYEE CHANGE IN CONTROL RETENTION INCENTIVE PLAN

WHEREAS , Quicksilver Resources Inc., a Delaware corporation (the “Company”), considers it to be in the best interests of its stockholders to encourage the continued employment of certain Key Employees (as defined herein) notwithstanding the possibility, threat or occurrence of a Change in Control (as defined herein);

WHEREAS , the Company believes that the possibility of the occurrence of a Change in Control may result in the termination by the Key Employee of the Key Employee’s employment by the Company or in the distraction of the Key Employee from the performance of his or her duties to the Company, in either case to the detriment of the Company and its stockholders;

WHEREAS , the Company recognizes that the Key Employee could suffer adverse financial and professional consequences if a Change in Control were to occur; and

WHEREAS , the Company has determined that it is advisable to establish a severance benefit program to protect the Key Employee if a Change in Control occurs, thereby encouraging the Key Employee to remain in the employ of the Company and not to be distracted from the performance of his or her duties to the Company by the possibility of a Change in Control.
