Explanation of Responses:

PSUs represent a contingent right to receive the value of one share of Cloud Peak Energy Inc. ("CPE") common stock. In general, PSUs vest 3 years from the date of grant depending on CPE's achievement of performance goals, which are based upon CPE's relative and absolute total shareholder return ("TSR"), and subject to the terms of the award agreement and CPE's long-term incentive plan ("LTIP"). These TSR achievements may result in a payout ranging between 0% and 200% of the target.
(2)  Represents the following awards of RSUs granted to the Reporting Person: 1,669 RSUs granted on 3/2/15, 7,055 RSUs granted on 3/4/16 and 3,071 RSUs granted on 3/3/17. Each RSU represents a contingent right to receive the value of one share of CPE common stock. In general, 100% of the RSUs vest three years after the date of grant subject to the terms of the award agreement and CPE's LTIP. Vested RSUs may be paid in shares, cash or a combination of shares and cash, in the discretion of the Compensation Committee.
