Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Reflects the number of shares of common stock withheld by the Issuer in satisfaction of the Reporting Person's tax withholding obligation upon the vesting of 2015 restricted stock units ("RSUs").
(2) Each 2015 performance share unit ("PSU") represented a contingent right to receive the value of one share of Cloud Peak Energy Inc. ("CPE") common stock. The PSUs vested 3 years from the date of grant (which was 3/2/2015) upon CPE's achievement of performance goals, which were based upon CPE's relative and absolute total shareholder return ("TSR"). These TSR achievements resulted in a payout of 100% of the target, which target number was originally reported in Table II on the Form 4 filed on 3/3/2015.
(3) Reflects the number of shares of common stock withheld by the Issuer in satisfaction of the Reporting Person's tax withholding obligation upon the vesting of 2015 PSUs.
(4) This total does not include RSUs granted to the Reporting Person in 2016, 2017 or 2018 because vested RSUs may be paid in shares, cash or a combination of shares and cash, in the discretion of the Compensation Committee.
(5) Each 2018 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 long-term incentive plan ("LTIP"). Vested RSUs may be paid in shares, cash or a combination of shares and cash, in the discretion of the Compensation Committee.
(6) This total does not include 2018 PSUs that were also granted on 3/2/2018 and that will be reported under Section 16 upon any vesting, as provided by applicable rules. PSUs represent a contingent right to receive the value of one share of 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 TSR, and subject to the terms of the award agreement and CPE's LTIP. These TSR achievements may result in a payout ranging between 0% and 200% of the target.
