Material Compensatory Plan for a Named Executive Officer
On February 2, 2007, the Board of Directors approved the 2007 Pension Equalization Plan of Black Hills Corporation (the "2007 PEP Plan").  The purpose of the 2007 PEP Plan is to provide a select group of management or highly compensated employees with retirement, disability and death benefits in addition to those benefits which the Participants may enjoy from the Company's tax qualified retirement plans in order to supplement and attempt to equalize total retirement benefits being paid to persons holding like executive and management positions by other companies.  The 2007 PEP Plan is designed to aid the Company in attracting and retaining its executive employees, persons whose abilities, experience and judgment can contribute to the well-being of the Company.
Participants in the 2007 Plan are designated by the Board of Directors.  A Participant's benefit shall consist of 180 equal monthly payments, each payment in the amount of one-twelfth of the product of:
(i)
two percent (2%) of the Participant's Average Earnings (as defined in the 2007 PEP Plan) as of the date of the Participant's Termination of Employment and the date the Participant's participation in the Plan is discontinued (the "Calculation Date")
times
(ii)
the Participant's Years of Service as an Officer (up to a maximum of 15 years) as of the Calculation Date
times
(iii)
the applicable vesting percentage as of the Calculation Date.
Benefits vest in accordance with the following table:
If, at Termination of Employment or, if earlier, Discontinuance of Participation, the Participant is
The Participant is entitled to the following percentage of his or her PEP Benefit

of Vesting Service
100%
Age 55 with fewer than 10 Years
of Vesting Service
0%
Under age 55
0%
2
Payment of vested benefits commence on the first day of the month following the later of (i) the date the Participant attains age 55 years of age or (ii) the date of the Participant's Termination of Employment for reasons other than death.  If payment begins before the Participant attains age 62, the vested PEP Benefit shall be subject to the discount for early commencement.
The Board of Directors also named the following Officers as Participants in the Plan with the following Officer Status and Vesting Service Dates:
