COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE
ANNUAL MEETING PROCESS

Q:    Who is soliciting my proxy?

A:

The Board of Directors of Black Hills Corporation.

Q:    Where and when is the annual meeting?

A:

9:30 a.m., local time, May 20, 2008 at The Journey Museum, 222 New York Street, Rapid City, South Dakota.

Q:    What am I voting on?

A:	•	Election of four directors in Class II: David R. Emery, Kay S. Jorgensen, Warren L. Robinson and John B. Vering.
	•	Ratification of Deloitte & Touche LLP as our independent registered public accounting firm for 2008.
	•	The consideration of a shareholder proposal that may be presented at the meeting, which the Board of Directors and management oppose, to recommend the annual election of all directors instead of electing directors for staggered three-year terms.

Q:    Who can vote?

A:

Holders of our common stock as of the close of business on the record date, April 1, 2008, can vote at our annual meeting. Each share of our common stock gets one vote. Cumulative voting is permitted in the election of directors. Each share is entitled to four votes, one each for the election of four directors, and the four votes may be cast for a single person or may be distributed among two, three or four persons.

Q:    How do I vote?

A:

There are three ways to vote by proxy:

•

by calling the toll free telephone number on the enclosed proxy;

•

by using the Internet; or

•

by returning the enclosed proxy in the envelope provided.

You may be able to vote by telephone or the Internet if your shares are held in the name of a bank or broker. If this is the case, you will need to follow their instructions.

If we receive your signed proxy before the annual meeting, we will vote your shares as you direct. You can specify on your proxy whether your shares should be voted for all, some or none of the nominees for directors. You can also specify whether you approve, disapprove or abstain from the other two proposals.

If you do not mark any sections, your proxy card will be voted:

•

in favor of the election of the directors named in Item 1;



•

in favor of Item 2; and



•

        You have the right to revoke your proxy any time before the meeting by:

•

entering a new vote by telephone or Internet;



•

notifying our secretary in writing;



•

sending a later dated proxy changing your vote; or



•

attending the meeting in person and revoking your proxy at any time before the proxy is exercised.

Q:    Who will count the vote?

A:

Representatives of Wells Fargo Bank, N.A. will count the votes and serve as judges of the election.

Q:    What constitutes a quorum?

A:

As of the record date, April 1, 2008, 38,397,919 shares of our common stock were issued and outstanding. In order to conduct the annual meeting, more than one-half of the outstanding shares must be present or be represented by proxy. This is referred to as a "quorum." If you submit a properly executed proxy card, you will be considered as part of the quorum. Proxies marked as abstaining and broker non-votes on any proposal to be acted on by shareholders will be treated as present at the annual meeting for purposes of determining a quorum.

Q:    What vote is needed for these proposals to be adopted?

A:

The affirmative vote of a plurality of the votes cast at the meeting is required for the election of directors. This means that the nominees with the largest number of votes "for" will be elected as directors, up to the maximum number of directors to be chosen at the election. A properly executed proxy marked "Withhold authority" with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum.

The appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year 2008 will be ratified if a majority of the shares represented at the meeting and entitled to vote on the item, vote in favor.

The shareholder proposal to recommend the annual election of all directors requires the affirmative vote of the holders of a majority of the shares represented at the meeting and entitled to vote on the item to approve the proposal. Shareholders should be aware that this shareholder proposal is simply a request that the Board take the action stated in the proposal. Approval of this proposal may not result in the requested action being taken by the Board of Directors. Under South Dakota law, the Board of Directors must approve an amendment to its Articles of Incorporation and Article VI of our Articles of Incorporation requires an affirmative vote of the holders of at least 80 percent of the outstanding shares of our common stock to change the structure of our Board of Directors.

A properly executed proxy marked "Abstain" with respect to the ratification of the appointment of Deloitte & Touche as our independent registered public accounting firm and the shareholder proposal to recommend the annual election of directors will have the effect of a negative, or "no" vote.

If you hold your shares in "street name" through a broker or nominee, your broker or nominee may not be permitted to exercise voting discretion with respect to some of the matters to be acted upon. Thus, if you do not give your broker or nominee specific instructions, your shares may not be voted on those matters and will not be counted in determining the number of shares necessary

for approval. Shares represented by such "broker non-votes" will, however, be counted in determining whether there is a quorum.

Q:    Is cumulative voting permitted for the election of directors?

A:

In the election of directors, you may elect to cumulate your vote. Cumulative voting will allow you to allocate among the director nominees, as you see fit, the total number of votes equal to the number of director positions to be filled multiplied by the number of shares you hold. For example, if you own 100 shares of stock, and there are four directors to be elected at the annual meeting, you could allocate 400 "For" votes (four times 100) among as few or as many of the four nominees to be voted on at the annual meeting as you choose.

If you choose to cumulate your votes, you will need to submit a proxy card or a ballot and make an explicit statement of your intent to cumulate your votes, either by indicating in writing on the proxy card or by indicating in writing on your ballot when voting at the annual meeting. If you hold shares beneficially in street name and wish to cumulate votes, you should contact your broker, trustee or nominee.

Q:    What should I do now?

A:

You should vote your shares by telephone, by the Internet or by returning your signed and dated proxy card in the enclosed envelope as soon as possible so that your shares will be represented at the annual meeting.

Q:    Who conducts the proxy solicitation and how much will it cost?

A:

We are asking for your proxy for the annual meeting and will pay all the cost of asking for shareholder proxies. We have hired Georgeson Inc. to help us send out the proxy materials and ask for proxies. Georgeson Inc.'s fee for these services is anticipated to be $7,000, plus out-of-pocket expenses. We can ask for proxies through the mail or by telephone, fax, or in person. We can use our directors, officers and employees to ask for proxies. These people do not receive additional compensation for these services. We will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding solicitation material to the beneficial owners of our common stock.

Q:    Can I revoke my proxy?

A:

Yes. You can change your vote in one of four ways at any time before your proxy is used. First, you can enter a new vote by telephone or Internet. Second, you can revoke your proxy by written notice. Third, you can send a later dated proxy changing your vote. Fourth, you can attend the meeting and vote in person.

Q:    How will my shares be voted if they are held in a broker's name?

A:

Your broker may vote shares nominally held in its name, or in what is commonly called "street name," under some circumstances, only if you provide the broker with written instructions on how to vote.

Q:    What happens if I do not give my broker instructions?

A:

Absent your instructions, under some circumstances, these shares will not be voted. Therefore, we urge you to instruct your broker in writing to vote shares held in street name.

Q:    Who should I call with questions?

A:

If you have questions about the annual meeting, you should call Roxann R. Basham, Vice President—Governance and Corporate Secretary, at (605) 721-1700.

Q:    When are the shareholder proposals for the annual meeting held in 2009 due?

A:

In order to be considered, you must submit proposals for next year's annual meeting in writing to our Corporate Secretary at our executive offices at 625 Ninth Street, P.O. Box 1400, Rapid City, South Dakota 57709, prior to December 10, 2008.

Proposal 1

ELECTION OF DIRECTORS

        In accordance with our Bylaws and Article VI of our Articles of Incorporation, members of our Board of Directors are elected to three classes of staggered terms consisting of three years each. At this annual meeting of our shareholders, four directors will be elected to Class II of the Board of Directors to hold office for a term of three years until our annual meeting of shareholders in 2011, and until their respective successors shall be duly elected and qualified in accordance with the Company's Bylaws.

        All four nominees for directors are presently members of our Board of Directors. Mr. Robinson was elected by the Board of Directors in April 2007 and is nominee for election for the first time. Mr. Robinson was recommended for nomination by our Chief Executive Officer. The proxy attorneys will vote your stock for the election of the four nominees for directors, unless otherwise instructed. If, at the time of the meeting, any of such nominees shall be unable to serve in the capacity for which they are nominated or for good cause will not serve, an event which the Board of Directors does not anticipate, it is the intention of the persons designated as proxy attorneys to vote, at their discretion, for such nominees as the Governance Committee may recommend and the Board of Directors may propose to replace those who are unable to serve. The affirmative vote of a plurality of the votes cast at the meeting is required for the election of the nominees to the Board of Directors.

CORPORATE GOVERNANCE

        Corporate Governance Guidelines.    Our Board of Directors has adopted corporate governance guidelines titled "Corporate Governance Guidelines of the Board of Directors" which set the tone for operation of our Board and assist the Board in fulfilling its obligations to shareholders and other constituencies. The guidelines lay the foundation for the Board's responsibilities, operations, leadership, organization and committee matters. The Governance Committee reviews the guidelines annually, and the guidelines may be amended at any time, upon recommendation by the Governance Committee and approval of the Board.

        Board Independence.    In accordance with New York Stock Exchange rules, the Board of Directors through its Governance Committee affirmatively determines the independence of each director and director nominee in accordance with guidelines it has adopted, which include all elements of independence set forth in the New York Stock Exchange listing standards. These guidelines are contained in our Policy for Director Independence, which can be found in the "Governance" section of our website (www.blackhillscorp.com/corpgov.htm). Based on these standards, the Governance Committee determined that each of the following nonemployee directors is independent and has no relationship with the Company, except as a director and shareholder of the Company:

        In addition, based on such standards, the Governance Committee determined that Mr. Emery is not independent because he is our Chairman, President and Chief Executive Officer (the "CEO").

        Presiding Director and Executive Sessions.    The Board has a Presiding Director position that is named annually. Kay S. Jorgensen has been serving as our Presiding Director since May 2006. The responsibilities of Presiding Director, as provided in the Board's Governance Guidelines, are to chair executive sessions of the non-management directors and communicate the Board's annual evaluation of the CEO. The Presiding Director, together with the non-management directors, establishes the agenda for executive sessions, which are held at the end of each regular Board meeting. The Presiding Director serves as a liaison between the non-management members of the Board and the CEO, and discusses, to the extent appropriate, matters discussed by the non-management directors in executive session. The Presiding Director also presides over regular meetings of the Board in the absence of the Chairman.

        Consideration of Director Nominees.    The Governance Committee utilizes a variety of methods for identifying and evaluating nominees for director. The Committee regularly assesses the appropriate size of the Board, and whether any vacancies on the Board are expected due to retirement or otherwise. In the event vacancies are anticipated, or otherwise arise, the Committee considers various potential candidates for director. Board candidates are considered based upon various criteria, including diverse business, administrative and professional skills or experiences; an understanding of relevant industries, technologies and markets; financial literacy; independence status; the ability and willingness to contribute time and special competence to Board activities; personal integrity and independent judgment; and a commitment to enhancing shareholder value. The Committee considers these and other factors as it deems appropriate, given the current needs of the Board and the Company. The Committee considers candidates for Board membership suggested by a variety of sources, including current or past Board members, members of management and shareholders. There are no differences in the manner by which the Committee evaluates director candidates recommended by shareholders from those recommended by other sources. The Committee has also retained a third-party executive search firm at times to identify candidates.

---

        Nominations from our shareholders for membership on the Board of Directors will be considered by the Governance Committee. A shareholder who wishes to submit names for future consideration for Board membership should do so in writing, with whatever supporting material the shareholder considers appropriate, addressed to Governance Committee, c/o Corporate Secretary, Black Hills Corporation, P.O. Box 1400, Rapid City, South Dakota 57709.

        Communications with the Board.    Shareholders and others interested in communicating directly with the Presiding Director, with the non-management directors as a group, or the Board of Directors may do so in writing to the Presiding Director, Black Hills Corporation, P.O. Box 1400, 625 Ninth Street, Rapid City, South Dakota, 57709.

        Policy on Related Party Transactions.    We recognize related party transactions can present potential or actual conflicts of interest and create the appearance that decisions are based on considerations other than the best interests of the Company and our shareholders. Accordingly, as a general matter, it is our preference to avoid related party transactions. Nevertheless, we recognize that there are situations where related party transactions may be in, or may not be inconsistent with, the best interests of the Company and our shareholders, including but not limited to situations where we may obtain products or services of a nature, quantity or quality, or on other terms, that are not readily available from alternative sources or when we provide products or services to related parties on an arm's length basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to employees generally. Therefore, our Board of Directors has adopted a policy for the review of related party transactions. This policy requires directors and officers to promptly report to our Vice President—Governance all proposed or existing transactions in which the Company and they, or persons related to them, are parties or participants. Our Vice President—Governance presents to our Governance Committee those transactions that may require disclosure pursuant to Item 404 of Regulation S-K (typically, those transactions that exceed $120,000). Our Governance Committee reviews the material facts presented and either approves or disapproves entry into the transaction. In reviewing the transaction, the Governance Committee considers the following factors, among other factors it deems appropriate: (i) whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances; (ii) the extent of the related party's interest in the transaction; and (iii) the impact on a director's independence in the event the related party is a director, an immediate family member of a director or an entity in which a director is a partner, shareholder or executive officer.

        Corporate Governance Documents.    The charters of the Audit, Compensation, Executive and Governance committees, as well as the Board's Corporate Governance Guidelines, Policy for Director Independence, Code of Business Conduct and the Code of Ethics that applies to our Chief Executive Officer, Chief Financial Officer, Corporate Controller, and certain other persons performing similar functions can be found in the "Governance" section of our website (www.blackhillscorp.com/corpgov.htm). Copies may also be obtained upon request from our Corporate Secretary. Please note that none of the information contained on our website is incorporated by reference in this proxy statement.

        Section 16(a) Beneficial Ownership Reporting Compliance.    Based solely upon a review of our records and copies of reports on Form 3, 4 and 5 furnished to us, we believe that during and with respect to 2007, all persons subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934, as amended, filed the required reports on a timely basis, except for one Form 4 for Mr. Eugster that was filed one day late relating to the acquisition of phantom stock under the Outside Directors Stock Based Compensation Plan.

MEETINGS AND COMMITTEES OF THE BOARD

The Board of Directors

        Our directors review and approve our strategic plan and oversee management of the Company. Our Board of Directors held 16 meetings during 2007. Directors' attendance at all Board and Committee meetings averaged 99 percent. During 2007, every director attended at least 75 percent of the combined total of Board meetings and Committee meetings on which the director served. Each regularly scheduled meeting of the Board includes an executive session of only non-management directors. We encourage our directors to attend the annual shareholders' meeting. All 10 directors were in attendance at the 2007 annual meeting of shareholders.

Committees of the Board

        Our Board has four standing committees to facilitate and assist the Board in the execution of its responsibilities. The committees are currently the Audit Committee, the Compensation Committee, the Governance Committee and the Executive Committee. In accordance with the New York Stock Exchange listing standards and our Corporate Governance Guidelines, the Audit, Compensation and Governance Committees are comprised solely of non-employee, independent directors. Each committee operates under a charter which is available on our website at www.blackhillscorp.com/corpgov.htm and is also available in print to any shareholder who requests it.

        Members of the Committees are designated by our directors upon recommendation of the Governance Committee. The table below shows current membership for each of the Board committees.

Committee Chairperson

        Audit Committee.    The Audit Committee held eight meetings in 2007. The Audit Committee's responsibilities, discussed in detail in its charter include, among other duties, the responsibility to:

•

assist the Board in fulfilling its responsibility for oversight of the quality and integrity of our accounting, auditing and financial reporting practices;



•

monitor the integrity of our financial reporting process, systems of internal controls and disclosure controls regarding finance, accounting and legal compliance;



•

review areas of potential significant financial risk to the Company;



•

review consolidated financial statements and disclosures;



•

appoint an independent registered public accounting firm for ratification by our shareholders;



•

monitor the independence and performance of our independent registered public accountants and internal auditing department;



•

pre-approve all audit and non-audit services provided by our independent registered public accountants;



•

review the scope and results of the annual audit including reports and recommendations of our independent registered public accountants;

9

---

•

review the internal audit plan, results of internal audit work and monitor compliance with our Code of Conduct; and



•

periodically meet with our internal audit group, management, and independent registered public accounting firm.

        In accordance with the rules of the NYSE, all of the members of the Audit Committee are financially literate. The Board determined that Messrs. Howard, Robinson, Vering and Zeller each have the requisite attributes of an "audit committee financial expert" as provided in regulations promulgated by the Securities and Exchange Commission, and that such attributes were acquired through relevant education and/or experience.

        Compensation Committee.    The Compensation Committee held five meetings in 2007. The Compensation Committee's responsibilities, discussed in detail in its charter include, among other duties, the responsibility to:

•

approve and oversee the implementation of the executive and director compensation philosophy, policies and programs;



•

perform functions required by the Board of Directors in the administration of all federal and state statutes relating to employment and compensation;



•

consider and recommend for approval by the Board all executive compensation programs including benefits, stock option plans and stock ownership plans; and



•

promote an executive compensation program that supports the overall objective of enhancing shareholder value.

        The Compensation Committee has authority under its charter to retain and terminate compensation consultants, outside counsel and other advisors as the Committee may deem appropriate in its sole discretion. The Committee has sole authority to approve related fees and retention terms. The Committee may delegate any of its responsibilities to subcommittees as the Committee may deem appropriate in its sole discretion. The Committee engaged Hewitt Associates, an independent consulting firm, to conduct an annual review of its 2007 total compensation program for executive officers and non-employee directors.

        The Committee annually evaluates the CEO's performance in light of established goals and objectives, with input from the other independent directors. Based upon the Committee's evaluation and recommendation, the independent directors of the Board set the CEO's annual compensation, including salary, bonus, incentive and equity compensation and perquisites.

        The CEO annually reviews the performance of each of our senior officers. He presents a summary of his evaluations of the Chief Operating Officer—Utilities (the "COO-Utilities,") the Chief Operating Officer—Non-regulated Energy Group (the "COO-Non-regulated Energy") and the Executive Vice President and Chief Financial Officer (the "CFO") to the Compensation Committee. Based upon the Committee's review and recommendation, the Board of Directors sets the annual compensation of the COO-Utilities, COO-Non-regulated Energy and CFO, including salary, bonus, incentive and equity compensation and perquisites.

        The CEO also annually reviews the performance of our other senior officers and provides oversight of management's evaluations of our other officers. Senior officers assess performance of all officers reporting to them. Based upon these performance reviews, market analysis conducted by the compensation consultant and discussions with the human resources department, the CEO recommends the compensation of this group of officers to the Committee. The Committee may exercise its discretion in modifying any of the recommended compensation and award levels in its review and approval process.

        More information describing the Compensation Committee's processes and procedures for considering and determining executive compensation, including the role of our CEO and consultants in determining or recommending the amount or form of executive compensation, is included in the Compensation Discussion and Analysis.

        In setting non-employee director compensation, the Compensation Committee recommends the form and amount of compensation to the Board of Directors and the Board of Directors makes the final determination. In considering and recommending the compensation of non-employee directors, the Compensation Committee considers such factors as it deems appropriate, including historical compensation information, level of compensation necessary to attract and retain non-employee directors meeting our desired qualifications and market data. In the review of director compensation for 2007, the Compensation Committee retained Hewitt Associates to provide market information on non-employee director compensation, including annual board and committee retainers, board and committee meeting fees, committee chairperson fees, number of Board meetings and stock based compensation.

        Compensation Committee Interlocks and Insider Participation.    The Compensation Committee is comprised entirely of independent directors.

•

assess the size of the Board and membership needs and qualifications for Board membership;



•

recruit and recommend prospective directors to the Board to fill vacancies;



•

consider and recommend existing Board members to be renominated at our annual meeting of shareholders;

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

        This Compensation Discussion and Analysis is designed to provide shareholders with a better understanding of our compensation philosophy, core principles and decision-making process. It explains the compensation-related actions taken with respect to 2007 compensation for our executive officers included in the Summary Compensation Table (our "Named Executive Officers"). Our Named Executive Officers, based on 2007 positions and compensation levels, are:

•

David R. Emery, our CEO;



•

Mark T. Thies, our CFO in 2007 and 2006 (Mr. Thies resigned on January 18, 2008);



•

Thomas M. Ohlmacher, our COO-Non-regulated Energy;



•

Linden R. Evans, our COO-Utilities; and



•

Steven J. Helmers, our Senior Vice President and General Counsel.

        The Compensation Committee of the Board of Directors (the "Committee," for purposes of this Compensation Discussion and Analysis) is composed entirely of independent directors and is responsible for approving and overseeing the implementation of our executive compensation philosophy, policies and programs. The Committee has a written executive compensation philosophy which details the objectives of our executive compensation program.

        Compensation Philosophy.    Our long-term success depends on our ability to operate effectively and efficiently, offering reliable service to our customers and investing wisely for present and future success. To achieve these goals, we must attract, motivate, and retain highly talented individuals. For these reasons, the Committee seeks to promote an executive compensation program that supports the overall objective of enhancing shareholder value and is based on principles designed to:

•

attract, retain and encourage the development of highly qualified and motivated executives;



•

provide compensation that is competitive;



•

promote the relationship between pay and performance;



•

promote overall corporate performance that is linked to the interests of our shareholders; and



•

recognize and reward outstanding performance.

        The market for our senior executive talent is national in scope and is not focused on any one geographic location, area or region of the country. As such, our executive compensation should be competitive with the national market place for senior executives. Beginning in 2008, the Committee has changed the market for our corporate executives from the general and diversified energy industry to the utility and energy industry, recognizing the significant role our regulated utility operations will have in the future with the proposed acquisition of Aquila's electric utility in Colorado and its gas utilities in Colorado, Kansas, Nebraska and Iowa. The executive compensation should also reflect the executive's responsibilities and duties and be aligned with the pay of executives at companies or business units of comparable size and complexity.

        Overall, our goal is to provide total direct compensation (the sum of base salary, annual bonus and long-term incentives) at the median of the appropriate market when our operating results approximate average performance in relation to our peers. Individual executive's compensation may vary from the median based on such factors as individual skills, experience, contribution and performance, historic compensation, internal equity, retention concerns and other factors relevant to the individual executive.

12

---

Our executives' actual direct compensation should vary significantly based on how actual performance varies from average or target results.

        Our executive compensation is designed to maintain an appropriate and competitive balance between fixed and variable pay elements, short- and long-term compensation, and cash as well as stock-based compensation. We believe that the performance basis for determining compensation should differ by each reward element—base salary, annual bonus and long-term incentive compensation.

        Incentive measures (short- and long-term) should emphasize objective, quantitative operating measures. The Committee retains the right to positively or negatively adjust incentive payments based on their subjective evaluation of performance, including the materiality of certain extraordinary events.

        We have a policy that if an accounting restatement occurs after incentive payments have been made, due to the results of misconduct associated with financial reporting, the Committee will seek repayment of the incentive compensation from our CEO and CFO and has the discretion to request repayment of incentive compensation from our other officers, taking into consideration the individual roles and responsibilities prompting the restatement.

        We believe it is important for our officers to hold Company stock to further link performance to the interests of our shareholders. Consequently, we have stock ownership guidelines in place for all officers with minimum stock ownership levels that are based upon their level of responsibility.

        It is our philosophy to qualify, to the extent reasonably practicable, our executive officers' compensation for deductibility under applicable tax law. We reserve the flexibility necessary to provide total cash compensation in line with competitive practice, our compensation philosophy, and the Company's best interests, and may from time to time pay compensation to our executive officers that may not be deductible for tax purposes.

Setting Executive Compensation

        Based upon this compensation philosophy, the Committee structures our executive compensation to motivate our officers to achieve specified business goals and to reward them for achieving such goals.

        The Committee selects and retains the services of an independent consulting firm to:

•

provide information regarding practices and trends in compensation programs;



•

review and evaluate our compensation program as compared to compensation practices of other companies with similar characteristics, including size and type of business;



•

review and assist with the establishment of a peer group of companies; and



•

provide a compensation analysis of the executive positions.

        In 2007, the Company operated in a diverse collection of businesses; therefore, our comparator group was comprised of both utility and general industry companies. The Committee used the services of Hewitt Associates for evaluating 2007 compensation issues. Hewitt gathered data from its database, as well as from public and private surveys covering the utility and general industries.

        The salary surveys used by Hewitt Associates were:

•

Hewitt Associates: Total Compensation Measurement Database—Utility and General Industry;



•

Hewitt Associates: Power Industry Compensation Survey;



•

Hewitt Associates: Energy Marketing & Trading Survey;



•

Towers Perrin: Energy Services Industry, Executive Compensation Database;

13

---

•

ECS/Watson Wyatt: Top Management Report; and



•

ECI: Oil and Gas Industry Compensation Survey.

        The salary surveys are one of several inputs into the Committee's decisions regarding appropriate compensation levels. Other factors include company performance, individual performance, the level and nature of responsibilities, and discussions with the CEO and human resources department.

        An important component of the total compensation is derived from incentive compensation as discussed in our compensation philosophy above. The Committee reviews information provided by the compensation consultant to determine the appropriate level and mix of incentive compensation. Actual income in the form of incentive compensation is realized by the executive as a result of achieving Company goals and overall stock performance. The Committee believes that a significant portion of total target compensation should be comprised of incentive compensation.

        The Committee annually reviews tally sheets on all components of each executive officer's compensation, including salary, bonus, equity and other long-term incentive compensation values granted, the actual value realized from stock option exercises and restricted stock and restricted stock units vested, the value of all perquisites and other personal benefits, and the projected annual benefit under our Pension and Pension Equalization Plans. The Committee uses the tally sheets as a resource that concisely summarizes all elements of actual and potential future compensation of our officers facilitating the Committee's analysis of both the individual elements of compensation as well as the total aggregate amount of actual and projected compensation and internal pay relationships between the officer positions. In the review of tally sheets, the Committee concluded that both the annual compensation and the compensation mix were consistent with the Committee's expectations.

        Role of the Committee and Board in Setting Executive Compensation.    Each year the Committee evaluates the CEO's performance in light of established goals and objectives, with input from the other independent directors. Based upon the Committee's evaluation and recommendation, the independent directors of the Board set the CEO's annual compensation, including salary, bonus, incentive and equity compensation and perquisites.

        The Committee reviews the CEO's evaluation of the performance of the COO-Utilities, COO-Non-regulated Energy and the CFO in light of established goals and objectives. Based upon the Committee's review and recommendation, the Board of Directors sets the annual compensation of the COO-Utilities, COO-Non-regulated Energy and CFO, including salary, bonus, incentive and equity compensation and perquisites. The Committee also reviews and approves the CEO's recommendations for compensation of our other senior officers. The Committee is required to approve all decisions regarding equity awards to our officers.

        Role of Executive Officers in Compensation Decisions.    The CEO annually reviews the performance of each of our senior officers. He presents a summary of his evaluation of all of our senior officers to the Committee and thoroughly reviews the COO-Utilities, COO-Non-regulated Energy and CFO evaluations with the Committee. Based upon these performance reviews, market analysis conducted by compensation consultants and discussions with our human resources department, the CEO recommends the compensation of this group of officers to the Committee. The Committee may exercise its discretion in modifying any of the recommended compensation and award levels in its review and approval process.

Components of Executive Compensation

        The components of our executive compensation program consist of a base salary, an annual incentive plan, and a long-term incentive award program. In addition, we provide income for our officers' retirement and other benefits. In order to reward long-term growth as well as short-term results, the Committee establishes incentive targets that emphasize long-term compensation at a higher

14

---

level than short-term compensation. The components of total target compensation in 2007 were as follows:

        Base Salary.    Base salaries for all officers are reviewed annually. The base salary component is targeted at the median of the market data provided by the compensation consultant. The actual base salary of each officer is determined by the executive's performance, the experience level of the officer, the executive's current position in a market-based salary range, and internal pay relationships. Evaluation and approval of base salary adjustments normally occurs in December, with the adjustments effective in January of the following year. We also adjust the base salary of our executives at the time of a promotion or change in job responsibility, as appropriate. The Committee approved base salary increases for the Named Executive Officers ranging from 3.0% to 5.0% for 2007.

        Annual Incentive.    Our Short-Term Annual Incentive Compensation Program is designed to recognize and reward the contributions of individual executives as well as the contributions that group performance makes to overall corporate success. The program's goal for our corporate officers is based on earnings per share targets in order to closely align interests with shareholders and to foster teamwork and cooperation within the officer team. The annual incentive, after applicable tax withholding, is distributed to the officer in the form of 50 percent stock and 50 percent cash, unless the officer has met his or her stock ownership guideline whereby he or she has the option to receive the total award in cash, after applicable tax withholding. Target award levels are established as a percentage of each participant's base salary considering the appropriate compensation survey data. A target award is comparable to the average annual incentive payout award of the comparator group at the 50^th percentile level.

        The Committee approves the target level for each officer in December, which is applicable to performance in the following plan year. Target levels are derived in part from competitive data provided by the compensation consultant and in part by the Committee's judgment on internal equity of the positions and their value to the Company. The target levels for the positions held by our Named Executive Officers are shown below. The actual amount awarded to corporate officers ranges from zero to two times the target percentage depending on the performance level.

        The threshold, target and maximum payout levels for our Named Executive Officers under the 2007 Short-Term Annual Incentive Plan are shown in the Grants of Plan Based Awards in 2007 table under the heading "Estimated Possible Payouts Under Non-Equity Incentive Plan Awards."

        In February, the Committee meets to establish the goals for the current plan year, to evaluate actual performance in relation to the prior year's targets and to approve the actual payment of awards related to the prior plan year. The Committee reserves the discretion to adjust any award, and will review and take into account individual performance, level of contribution and the accomplishment of

15

---

specific project goals that were initiated throughout the plan year. In February 2007, the Committee approved the goals for the 2007 plan year for the corporate officers as follows:

        The target earnings per share goal for 2007 equaled 2007 budgeted earnings per share. In February 2008, the Committee approved a payout of 200 percent of target under the 2007 Short-Term Annual Incentive Plan as a result of our 2007 earnings per share of $2.64 exceeding the maximum earnings per share goal under the 2007 plan. The 2007 award, after applicable tax withholding, was distributed in the form of 50 percent stock and 50 percent cash for Mr. Emery and Mr. Evans. Mr. Thies, Mr. Ohlmacher and Mr. Helmers had met their stock ownership guidelines and elected to receive their 2007 award in the form of 100 percent cash. Awards for corporate officers under the Short-Term Annual Incentive Plan have varied significantly over the last five years as shown below.

        Actual awards made to each of our Named Executive Officers under the Short-Term Annual Incentive Plans for 2007 are included in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table.

        For 2008, the Committee reviewed the design of the Short-Term Annual Incentive Plan, addressing the volatility of our energy marketing segment's earnings and the potential that these earnings may disproportionately influence bonus outcomes for participants in the Short-Term Annual Incentive Plan. The Committee selected a modified earnings per share goal for the 2008 corporate goal that is weighted 80 percent on non-energy marketing earnings per share and 20 percent on energy marketing earnings per share. The Committee chose this weighted methodology because it aligns the plan more clearly with the ability of the majority of the employees to directly impact the results and it prevents the variability of earnings from our energy marketing segment from disproportionately influencing payouts of the plan, both positively and negatively. It also continues to meet the objectives of the plan including:

•

aligning the interests of the plan participants and the shareholders with a corporate-wide component;



•

motivating employees and supporting the corporate compensation philosophy;



•

being easily understood and easily communicated to ensure "buy-in" from the participants; and



•

by meeting the performance objectives of the plan, an average payout of target can be attained over time.

        Long-Term Incentive.    Long-term incentive compensation is comprised of grants made by the Committee under our 2005 Omnibus Incentive Plan ("Omnibus Incentive Plan") which was previously approved by our shareholders. Long-term incentive compensation is intended to:

•

promote corporate goals by linking the personal interests of participants to those of our shareholders;

16

---

•

provide participants with an incentive for excellence in individual performance;



•

promote teamwork among participants; and



•

provide flexibility in our effort to motivate, retain, and attract the services of participants who make significant contributions to our success by allowing participants to share in such success.

        The Committee oversees the administration of the Omnibus Incentive Plan with full power and authority to determine when and to whom awards will be granted, along with the type, amount and other terms and conditions of each award. The long-term incentive compensation component is currently composed of restricted stock (or restricted stock units) and performance shares. The Committee chose these components because they believe that executive compensation tied to stock price appreciation and total shareholder return is an effective way to align the interests of management with those of our shareholders. The Committee selected total shareholder return as the performance goal for the performance shares because it believes executive pay under a long-term, capital accumulation program such as this should mirror our performance in shareholder return as compared to our peer group of companies. None of our Named Executive Officers have received stock option grants since 2003. When stock options have been granted, they were granted with an exercise price equal to the fair market value of the common stock on the date of grant. No stock option back-dating occurred.

        The value of long-term incentives awarded is based primarily on competitive market-based data presented by the compensation consultant to the Committee, the impact each position has on our shareholder return and internal pay relationships. The Committee approves the target long-term incentive compensation level for each officer in December, which is awarded in January of the following year. Long-term incentive compensation approved for the 2007 plan year for our Named Executive Officers is shown in the table below.

        The variance in percentage of base salary for the long-term incentive value reflects our philosophy that the CEO and COOs should have more of their total compensation at risk because they are in positions that have a more direct impact on our long-term results.

        Restricted stock (or restricted stock units) are targeted to deliver 50 percent of the long-term incentive opportunity, with the remaining 50 percent delivered in the form of performance shares.

        Restricted Stock and Restricted Stock Units.    Restricted stock and restricted stock units vest one-third each year over a three-year period, and automatically vest in their entirety upon death, disability or a change in control. Dividends are paid on the restricted shares and dividend equivalents accrue on restricted stock units. Unvested restricted stock or units are forfeited if an officer's employment is terminated for any reason other than death, disability or in the event of a change in control. Restricted stock and restricted stock units granted prior to December 10, 2007 also automatically vest in their entirety upon retirement. Corporate officers may elect to receive the award in the form of restricted stock, or to defer the payment under the Nonqualified Deferred Compensation Plan, in the form of restricted stock units. Restricted stock award values are normally approved in December with a grant date effective in the first week in January of the following year. The number of shares awarded in 2007 for each of our Named Executive Officers are shown below and

17

are included in the Grants of Plan Based Awards in 2007 table under the heading "All Other Stock Awards: Number of Shares of Stock or Units" and "Grant Date Fair Value of Stock Awards."

        Performance Shares.    Participants are awarded a target number of performance shares based upon the value of the individual performance share component approved by the Committee, divided by the Beginning Stock Price. The Beginning Stock Price, as defined under the Performance Plan, is the average of the closing price of our common stock for the 20 trading days immediately preceding the beginning of the plan period. Entitlement to performance shares is based on our total shareholder return over designated performance periods, as measured against our peer group. In addition, in order for any performance shares to be awarded, our stock price must also increase during the performance period from the Beginning Stock Price. The final value of the performance shares is based upon the number of shares of common stock that are ultimately granted, based upon our performance in relation to the performance criteria. At the end of each respective performance period, actual awards may range from 0 percent to 175 percent of the target share amounts plus accrued dividends. A 100 percent payout of the target shares occurs if our total shareholder return exceeds the 50^th percentile of the peer group. For the performance period that ended in 2007 and the performance period that ends in 2008, a zero percent payout occurs if we are below the 30^th percentile. For the performance periods that end in 2009 and 2010, the minimum threshold for a payout was raised from the 30^th percentile to the 40^th percentile. For all the performance periods outstanding, the maximum payout of 175 percent occurs if we perform at the 80^th percentile or above. The performance awards and dividend equivalents, if earned, are paid in 50 percent cash and 50 percent common stock. All payroll deductions and applicable tax withholding related to the award are withheld from the cash portion. Performance share target grant values are normally approved in December for a three-year performance period beginning January 1 of the following year.

        Our peer group is comprised of the following companies for the performance periods that end in 2007, 2008 and 2009:

		Alliant Energy Corporation		NStar
		DPL Inc.		OGE Energy Corporation
		Great Plains Energy Incorporated		Pepco Holdings Inc.
		Hawaiian Electrics Inds.		PNM Resources Inc.
		IDACORP, Inc.		Puget Energy Inc.
		Integrys Energy Group, Inc.		Wisconsin Energy Corp.
		Northeast Utilities

        This peer group was originally identified as the companies in the S&P MidCap Electric Utilities Index; however because of re-categorizing of companies in the index by S&P from time to time, the companies in the peer group must be tracked individually.

        The Committee changed our peer group for the January 1, 2008 to December 31, 2010 Performance Period, recognizing a peer group that is more reflective of Black Hills Corporation upon

18

---

the closing of the proposed acquisition of Aquila's electric utility in Colorado and its gas utilities in Colorado, Kansas, Nebraska and Iowa. The new peer group is comprised of the following companies:

		AGL Resources Inc.		Otter Tail Corporation
		ALLETE Inc.		PNM Resources, Inc.
		Avista Corp		Portland General Electric Company
		CH Energy Group Inc.		Puget Energy, Inc.
		Cleco Corporation		Sierra Pacific Resources
		DPL Inc.		UIL Holdings Corporation
		Great Plains Energy Incorporated		UniSource Energy Corporation
		IDACORP, Inc.		Vectren Corporation
		MDU Resources Group, Inc.		Westar Energy, Inc.
		NorthWestern Corporation		WGL Holdings, Inc.

        Each performance share period is for three-years. For the recently completed performance period, January 1, 2005 to December 31, 2007, our total shareholder return was 58 percent, which ranked at the 87^th percentile of our peer group, resulting in a payout of 175 percent of target levels. The awards were paid in the form of 50 percent cash and 50 percent common stock. The actual shares, cash and total payout value awarded to our Named Executive Officers for the performance period were as follows:

Janaury 1, 2005 to December 31, 2007 Performance Period

		Equivalent Shares Earned		50% Awarded in Shares		50% Awarded in Cash			Total Payout Value
David R. Emery		14,339		7,169		$	311,737		$	623,446
Mark T. Thies		6,701		3,351		$	145,677		$	291,379
Thomas M. Ohlmacher		12,108		6,054		$	263,230		$	526,457
Linden R. Evans		7,643		3,821		$	166,179		$	332,316
Steven J. Helmers		5,088		2,544		$	110,599		$	221,212

        Target shares for each of our Named Executive Officers for the outstanding performance periods are as follows:

		January 1, 2006 to December 31, 2008 Performance Period		January 1, 2007 to December 31, 2009 Performance Period		January 1, 2008 to December 31, 2010 Performance Period
David R. Emery		7,326		8,163		6,900
Mark T. Thies		NA		NA		NA
Thomas M. Ohlmacher		5,303		5,170		4,370
Linden R. Evans		3,348		3,252		2,748
Steven J. Helmers		2,245		2,189		1,850

        Actual payouts, if any, will be determined based upon the total shareholder return for the plan period in comparison to the peer group.

        Stock Ownership Guidelines.    The Committee has implemented stock ownership guidelines that apply to all officers. We believe it is important for our officers to hold a significant amount of our common stock to further align their performance with the interest of our shareholders. A "retention ratio" approach to stock ownership is incorporated into the guidelines. This approach requires officers to retain 100 percent of all shares owned, including shares awarded through our incentive plans (net of share withholding for taxes and in the case of cashless stock option exercises net of the exercise price and withholding for taxes) until specific ownership goals are achieved. Ownership guidelines are denominated in share amounts which approximate a multiple of base pay.

        The ownership guidelines and current stock ownership of our Named Executive Officers are shown below.

Officer Level		Ownership Guideline (# of Shares)		Actual Ownership (# of Shares)		Years in Position
David R. Emery, CEO		90,000		71,116		4
Mark T. Thies, former CFO		40,000		15,834		NA
Thomas M. Ohlmacher, COO-Non-regulated Energy		40,000		40,544		6
Linden R. Evans, COO-Utilities		40,000		23,671		3
Steven J. Helmers, Senior Vice President & General Counsel		25,000		27,002		7

        Perquisites and Other Personal Benefits.    We provide a limited number of market-based perquisites to our executive officers which include financial planning services and personal use of a Company vehicle. The total value of these perquisites in 2007 for our Named Executive Officers ranged from $1,767 to $7,600. The perquisites' value was reported as taxable income to the officers and the officers were required to pay the applicable taxes. The Committee periodically reviews the perquisites and other personal benefits provided to our executive officers and believes the current perquisites are reasonable and consistent with our overall compensation program.

        Retirement and Other Benefits.    We currently maintain a variety of employee benefit plans and programs in which our executive officers may participate, including a 401(k) Retirement Savings Plan, the Pension Plan, the Pension Equalization Plan, 2007 Pension Equalization Plan and the Nonqualified Deferred Compensation Plan. We believe it is important to provide post-employment benefits to our executive officers and the benefits we provide approximate retirement benefits paid by other employers to its executives in similar executive positions. The Committee periodically reviews the benefits provided with assistance from its compensation consultant to maintain a market-based benefits package.

        The Black Hills Corporation 401(k) Retirement Savings Plan is offered to all eligible employees of the Company and its subsidiaries except for Cheyenne Light, Fuel and Power which has its own 401(k) Plan. All of our Named Executive Officers are participants in the Black Hills Corporation 401(k) Retirement Savings Plan. Participants may elect to invest up to 20 percent of their eligible compensation on a pre-tax basis up to maximum amounts established by the Internal Revenue Service. The Black Hills Corporation 401(k) Plan provides a matching contribution of 100 percent of the employee's annual tax-deferred contribution up to a maximum of 3 percent of eligible compensation. Matching contributions vest at 20 percent per year and are fully vested when the participant has five years of service with the Company. Each of our Named Executive Officers received the maximum annual contribution of $6,750 in 2007. The matching contribution is included as "All Other Compensation" in the Summary Compensation Table.

        The Black Hills Corporation Pension Plan covers the employees of Black Hills Corporation and a number of its subsidiary companies. The plan is a qualified defined benefit pension plan that provides benefits at retirement based on length of employment service and certain average compensation levels during the highest five consecutive years of the last ten years of service. Our employees do not contribute to the plan. Each of our Named Executive Officers are participants in the plan and none of our Named Executive Officers have been granted additional years of credited service.

        The defined benefit pension plan is limited by the Internal Revenue Code in the amount of annual payments received under the plan ($180,000 in 2007) and in the amount of compensation that can be taken into account in determining contributions and benefits ($225,000 in 2007). Because of these limitations we also have the Pension Equalization Plan and the 2007 Pension Equalization Plan. The level of retirement benefits provided by the Pension Plan, Pension Equalization Plan, 2007 Pension Equalization Plan and the Pension Restoration Benefit for each of our Named Executive Officers is

20

reflected in the Pension Benefits for 2007 table and explained in more detail in the accompanying narrative.

        The Pension Equalization Plan is a nonqualified supplemental retirement plan with a pension restoration benefit designed to provide the higher paid executive employee a retirement benefit which, when added to social security benefits and the pension to be received under the defined benefit pension plan, approximate retirement benefits paid by other employers to its employees in similar executive positions. The Board of Directors designates the participants in the Pension Equalization Plan. Each of our Named Executive Officers except Mr. Evans is a participant in the Pension Equalization Plan. The Pension Equalization Plan has been frozen to new participants since 2002.

        Several of our current corporate officers became officers after the Pension Equalization Plan was frozen to new participants. During 2006 and early 2007, the Committee, in consultation with Mercer Human Resource Consulting, an independent consultant engaged by the Committee, thoroughly reviewed the need to offer some form of supplemental retirement plan to officers. The Committee concluded that a supplemental retirement plan was needed for corporate officers who were not participants in the existing frozen Pension Equalization Plan in order to provide a benefits package consistent with market practices. In 2007, the Committee recommended and the Board of Directors approved the 2007 Pension Equalization Plan. The Board of Directors designated four corporate officers, including Mr. Evans, who were not participants in the existing Pension Equalization Plan as participants in the 2007 Pension Equalization Plan with years of credited service equal to the number of years they served as a corporate officer. Mr. Evans received two years of credited service. The main differences between the original Pension Equalization Plan and the 2007 Pension Equalization Plan are as follows:

Annual Benefit Amount

	Original Pension Equalization Plan		2007 Pension Equalization Plan
	25% of average earnings, if salary was less than two times the social security wage base, or 30%, if salary was more than two times the social security wage base, multiplied by the vesting percentage		2% of average earnings times the participant's years of service as an officer (up to a maximum of 15 years) times the applicable vesting percentage

Vesting Schedule

Original Pension Equalization Plan				2007 Pension Equalization Plan
Years of Plan Participation		Vesting %		Age at Termination of Employment or Discontinuance of Participation		Vesting %
Less than 3 years		0	%	Age 65 or over		100	%
3 years but less than 4		20	%	Age 55 with over 10 years of vesting service		100	%
4 years but less than 5		35	%	Age 55 with less than 10 years of service		0	%
5 years but less than 6		50	%	Under age 55		0	%
6 years but less than 7		65	%
7 years but less than 8		80	%
8 or more years		100	%

        The Nonqualified Deferred Compensation Plan allows our corporate officers to elect to defer up to 50 percent of their base salary and up to 100 percent of their Short-Term Annual Incentive Plan award, including Company stock, and elect to defer restricted stock grants in the form of restricted stock units. We make no contributions to the plan. None of our Named Executive Officers are currently contributing to the Nonqualified Deferred Compensation Plan. The deferred balance in the plan for each of our Named Executive Officers is shown in the Nonqualified Deferred Compensation for 2007 table.

        Our Named Executive Officers may also receive severance benefits in the event of a change in control. Change in control agreements are common among our peer group and the Committee and our Board of Directors believe providing these agreements to our corporate officers protect our shareholder interests in the event of a change in control by helping assure management focus and continuity. Our change in control agreements have termination dates and our Board of Directors conduct a thorough review of the change in control agreements before renewing them. There are currently 10 change in control agreements in place with a term ending June 1, 2008. In general, our change in control agreements provide a severance payment of up to 2.99 times average compensation for our CEO and up to two times average compensation for our other corporate officers. The change in control agreement for our CEO contains a "modified trigger," providing benefits in association with a change in control upon:

(i)

termination of employment other than by death, disability or by the Company for cause,



(ii)

a termination by the CEO for good reason, or



(iii)

a termination by the CEO for any reason during a 30-day window period immediately following the first anniversary of a change in control.

        The change in control agreements for our other corporate officers contain a "double trigger," providing benefits in association with a change in control only upon:

(i)

termination of employment other than by death, disability or by the Company for cause, or



(ii)

a termination by the employee for good reason.

        See the Potential Payments Upon Termination or Change in Control table and the accompanying narrative for more information regarding our change in control agreements and estimated payments associated with a change in control.

        Deductibility of Executive Compensation.    Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended, limits the tax deductibility by a corporation of compensation in excess of $1 million paid to its CEO and any of its four most highly compensated executive officers. Compensation which qualifies as "performance-based" is excluded from the $1 million limit, if, among other requirements, the compensation is payable only upon attainment of pre-established, objective performance goals under a plan approved by the corporation's shareholders. As a result, the Compensation Committee has designed a large share of our incentive compensation for the Named Executive Officers to qualify for the exemption of "performance-based" compensation from the deductibility limit. However, the Compensation Committee does have the discretion to design and use compensation elements that may not be deductible under Section 162(m) if it determines those elements are in our best interests. We believe the compensation paid to our Named Executive Officers in 2007 is fully deductible.

COMPENSATION COMMITTEE REPORT

        The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Company's Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

SUMMARY COMPENSATION TABLE

        The following table sets forth the total compensation paid or earned by each of our Named Executive Officers for the fiscal years ended December 31, 2007 and December 31, 2006. We have no employment agreements with our Named Executive Officers. Amounts listed under the heading "Non-Equity Incentive Plan Compensation" represent amounts earned under the Short-Term Annual Incentive Plan for 2007 and 2006, respectively. The Compensation Committee approved the payout of the 2007 awards at its February 1, 2008, meeting and the awards were paid on February 26, 2008.

        Based on the fair value of equity awards granted to our Named Executive Officers in 2007 and the base salary of our Named Executive Officers, base salary accounted for 36 percent to 51 percent of total compensation, short-term annual incentive accounted for 18 percent to 25 percent of total compensation and long-term incentive accounted for 31 percent to 43 percent of total compensation. Because the table below reflects the value of certain equity awards based on the Statement of Financial Accounting Standards 123(R), "Share-Based Payment," ("FAS 123(R)") value rather than the fair value, these percentages cannot be derived using the amounts reflected in the table below.

(1)

Mr. Ohlmacher's 2006 bonus reflects a $32,000 relocation bonus to compensate for additional state income taxes.

(2)

Stock Awards represent the annual compensation expense related to restricted stock, restricted stock units and performance shares that have been granted as a component of Long-Term Incentive Compensation. The amount reported is the amount recognized for financial statement reporting purposes computed in accordance with FAS 123(R), and therefore includes amounts for awards granted in prior years. Assumptions used in the calculation of these amounts are included in Note 9 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2007.

Mr. Ohlmacher turned age 55 in September 2006 which made him eligible for early retirement. Because our restricted stock and restricted stock units granted prior to December 10, 2007 fully vest at retirement, the fair value of $190,000 associated with Mr. Ohlmacher's awards granted in each of 2007 and 2006 was all recognized in the year of grant in accordance with FAS 123(R), rather than expensing the award over the normal three year vesting period.

(3)

Option Awards represent the annual compensation expense related to stock options that have been granted as a component of Long-Term Incentive Compensation in prior years. The amount reported is the amount recognized for financial statement reporting purposes computed in accordance with FAS 123(R), and therefore includes amounts for awards granted in prior years. Assumptions used in the calculation of these amounts are included in Note 9 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2007.

(4)

Non-Equity Incentive Plan Compensation represents amounts earned under the Short-Term Annual Incentive Plan.

(5)

Change in Pension Value and Nonqualified Deferred Compensation Earnings represents the increase in actuarial value of the Defined Benefit Pension Plan, Pension Restoration Benefit ("PRB"), Pension Equalization Plan ("PEP"), and 2007 Pension Equalization Plan ("2007 PEP") for the respective year. No Named Executive Officer received preferential or above-market earnings on nonqualified deferred compensation. The value attributed from each plan to each Named Executive Officer is shown in the table below. Mr. Evans was not a participant in the PRB or PEP in 2007 and 2006. Mr. Evans is the only Named Executive Officer participating in the 2007 PEP.

(6)

All Other Compensation includes amounts allocated under the 401(k) match, dividends received on restricted stock and unvested restricted stock units and perquisites. Perquisites provided to our Named Executive Officers include personal use of a Company vehicle and financial planning services for 2007 and 2006 and club dues in 2006 only.

(7)

Mr. Thies resigned from the Company on January 18, 2008. Mr. Thies's severance agreement is disclosed under the caption "Severance Agreement."

No stock options were granted to our Named Executive Officers in 2007.

(2)

The columns under "Estimated Possible Payouts Under Non-Equity Incentive Plan Awards" show the range of payouts for 2007 performance under the Short-Term Annual Incentive Compensation Program as described in the Compensation Discussion and Analysis under the section titled "Annual Incentive." If the performance criteria is met, payouts can range from 30 percent of target at the threshold level to 200 percent of target at the maximum level. The 2008 bonus payment for 2007 performance has been made based on achieving the criteria described in the Compensation Discussion and Analysis, at 200 percent of target, and is shown in the Summary Compensation Table in the column titled "Non-Equity Incentive Plan Compensation."

(3)

The columns under "Estimated Future Payouts Under Equity Incentive Plan Awards" show the range of payouts (in shares of stock) for the January 1, 2007 to December 31, 2009 performance period as described in the Compensation Discussion and Analysis under the section titled "Long-Term Incentive—Performance Shares." If the performance criteria are met, payouts can range from 1 percent of target to 175 percent of target. If a participant retires, suffers a disability or dies during the performance period, the participant or the participant's estate is entitled to that portion of the number of performance shares as such participant would have been entitled to had he or she remained employed, prorated for the number of months served. Performance shares are forfeited if employment is terminated for any other reason. During the performance period, dividends and other distributions paid with respect to the shares of common stock shall accrue for the benefit of the participant and are paid out at the end of the performance period.

(4)

The column "All Other Stock Awards" reflects the number of shares of restricted stock granted on January 5, 2007 under our 2005 Omnibus Incentive Plan. The restricted stock vests one-third a year over a three-year period, and automatically vests upon death, disability, retirement or a change in control. Unvested restricted stock is forfeited if employment is terminated for any other reason. Dividends are paid on the restricted shares and the dividends that were paid in 2007 are included in the column titled "All Other Compensation" in the Summary Compensation Table.

(5)

The column "Grant Date Fair Value of Stock Awards" reflects the grant date fair value of each equity award computed in accordance with FAS 123(R). The grant date fair value for the performance shares was $34.17 per share and was calculated using a Monte Carlo simulation model. Assumptions used in the calculation are included in Note 9 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2007. The grant date fair value for the restricted stock was $37.11 per share which was the market value of our common stock on the date of grant as reported on the New York Stock Exchange.

PENSION BENEFITS FOR 2007

        Pension benefits for our Named Executive Officers can be comprised of a qualified defined benefit pension, a nonqualified pension restoration benefit and a supplemental pension benefit. None of our Named Executive Officers received any pension benefit payments during the fiscal year ended December 31, 2007.

(1)

The number of years of credited service represents the number of years used in determining the benefit for each plan. The Pension Equalization Plan and 2007 Pension Equalization Plan benefits are not directly tied to service but rather the number of years of participation in the plan.

(2)

The present value of accumulated benefits was calculated assuming benefits commence at age 62 and using the discount rate, mortality rate and assumed payment form assumptions consistent with those disclosed in Note 17 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2007.

(3)

Mr. Evans is not a current participant in the Pension Restoration Benefit and is a participant in the 2007 Pension Equalization Plan rather than the original Pension Equalization Plan. See the discussion on the plan benefits below.

Defined Benefit Pension Plan

        We have a Defined Benefit Retirement Plan, a qualified pension plan, in which our Named Executive Officers are included. Participants become eligible for the benefit when they have been employed by us for at least one year and are at least 21 years of age. The plan provides benefits at retirement based on length of employment service and average compensation levels during the highest five consecutive years of the last ten years of service. For purposes of the benefit calculation, earnings include wages and other cash compensation received from the Company, including any bonus, commission, unused paid time off or incentive compensation. It also includes any elective before-tax contributions made by the employee to a Company sponsored cafeteria plan or 401(k) plan. However, it does not include any expense reimbursements, taxable fringe benefits, moving expenses or moving/relocation allowances, nonqualified deferred compensation, non-cash incentives, stock options and any payments of long-term incentive compensation such as restricted stock or payments under performance share plans. The Internal Revenue Code places maximum limitations on the amount of compensation

28

---

that may be recognized when determining benefits of qualified pension plans. In 2007, the maximum amount of compensation that could be recognized when determining compensation was $225,000 (called "covered compensation").

        The benefit formula for the Named Executive Officers is the sum of (a) and (b) below.

(a)

Credited Service after January 31, 2000

(b)

Credited Service before January 31, 2000

        Pension benefits are not reduced for social security benefits. The Internal Revenue Code places maximum limitations on annual benefit amounts that can be paid under qualified pension plans. In 2007, the maximum benefit payable under qualified pension plans was $180,000. Accrued benefits become 100 percent vested after an employee completes five years of service. None of our Named Executive Officers have been credited with extra years of credited service under the plan.

        Normal retirement is defined as age 65 under the plan. Participants who have completed at least five years of credited service can retire and receive defined benefit pension benefits as early as age 55. However, the retirement benefit will be reduced by five percent for each year of retirement before age 62. For example, a participant with at least five years of credited service may retire at age 55 and receive a pension benefit equal to 65 percent of the normal retirement benefit. A participant with five years of service who retires from the Company may begin receiving retirement benefits on an unreduced basis at age 62. Mr. Ohlmacher is currently age 56 and is entitled to early retirement benefits under this provision.

        If a participant is vested and leaves the Company before reaching his or her earliest retirement date, he or she may begin receiving the full value of his or her vested benefit at age 65 or can receive a reduced benefit as early as age 55 if he or she has at least five years of credited service when he or she leaves employment of the Company. The benefit will be reduced by five percent for each year he or she begins receiving benefits prior to age 65. For example, a participant who leaves the Company before reaching age 55 with at least five years of credited service may begin receiving benefits at age 55 equal to 50 percent of the normal retirement benefit and may begin receiving retirement benefits at age 65 on an unreduced basis.

        If a participant is single, the benefit is paid as a life annuity. If a participant is married, the benefit is paid as a joint and 50 percent survivor annuity unless an optional form of payment is chosen.

        Our employees do not contribute to the plan. The amount of the annual contribution by us to the plan is based on an actuarial determination.

Pension Equalization Plan, 2007 Pension Equalization Plan and Pension Restoration Benefit

        We also have a Pension Equalization Plan, a 2007 Pension Equalization Plan and a Pension Restoration Benefit, nonqualified supplemental plans, in which benefits are not tax deductible until paid. The plans are designed to provide the higher paid executive employee a retirement benefit which, when added to social security benefits and the pension to be received under the Defined Benefit Pension Plan, will approximate retirement benefits being paid by other employers to its employees in similar executive positions. The employee's pension from the qualified pension plan is limited by the Internal Revenue Code. The 2007 limit was set at $180,000 annually and the compensation taken into account in determining contributions and benefits could not exceed $225,000 and could not include nonqualified deferred compensation. The amount of deferred compensation paid under nonqualified plans is not subject to these limits.

        Pension Equalization Plan.    A participant under the Pension Equalization Plan does not qualify for benefits until the benefits become vested under the following vesting schedule. The vesting is based on years of employment under the plan, not total years of service with the Company. No credit for past service is granted under the Pension Equalization Plan.

        The annual benefit is 25 percent of the employee's average earnings, if salary was less than two times the Social Security Wage Base, or 30 percent, if salary was more than two times the Social Security Wage Base, multiplied by the vesting percentage. Average earnings are normally an employee's average earnings for the five highest consecutive full years of employment during the ten full years of employment immediately preceding the year of calculation. The annual Pension Equalization Plan benefit is paid on a monthly basis for 15 years to each participating employee and, if deceased, to the employee's designated beneficiary or estate, commencing at the earliest of death or when the employee is both retired and 62 years of age or more. A participant with vested benefits who is 55 years of age or older and no longer an employee of the Company may elect to be paid benefits beginning at age 55 or older, subject to a discount of such benefits according to the following schedule.

        Participants in the Pension Equalization Plan were designated by our Board of Directors upon recommendation of the Chief Executive Officer. Mr. Emery, Mr. Thies, Mr. Ohlmacher and Mr. Helmers are participants in the Pension Equalization Plan. The Pension Equalization Plan has been frozen to new participants since 2002.

30

---

        2007 Pension Equalization Plan.    During 2006 and 2007, the Compensation Committee reviewed the need to offer some form of supplemental retirement plan to officers and concluded that a supplemental retirement plan was needed for corporate officers who were not participants in the original frozen Pension Equalization Plan. In 2007, the Board of Directors approved the 2007 Pension Equalization Plan and designated the four corporate officers, including Mr. Evans, who were not participants in the original Pension Equalization Plan as participants in the 2007 Pension Equalization Plan. The four participants were given years of credited service equal to the number of years they served as a corporate officer. Mr. Evans received two years of credited service.

        A participant under the 2007 Pension Equalization Plan does not qualify for benefits until the benefits become vested under the following vesting schedule. The vesting is based on age at termination and years of service under the plan, not total years of service with the Company.

        The annual benefit is 2 percent of the employee's average earnings multiplied by the participant's years of service as an officer (up to a maximum of 15 years) and the vesting percentage. Average earnings are normally an employee's average earnings for the five highest consecutive full years of employment during the ten full years of employment immediately preceding the year of calculation. The annual 2007 Pension Equalization Plan benefit is paid on a monthly basis for 15 years to each participating employee commencing at the later of 55 years of age or the date of the participant's termination of employment, unless the participant has elected otherwise. In the event of the participant's death before payment of the benefit begins, the vested benefit shall commence at the later of the date the participant would have attained age 55 years of age or the date of the participant's death. A participant or participant's beneficiary that receives payments under the plan prior to the participant attaining age 62 (or in the case of a beneficiary, would have attained age 62) shall receive such benefits subject to a discount of such benefits according to the same schedule as for the Pension Equalization Plan shown above.

        Pension Restoration Benefit.    In the event that at the time of a participant's retirement, the participant's salary level exceeds the qualified pension plan annual compensation limitation ($225,000 in 2007) or includes nonqualified deferred compensation, then the participant shall receive an additional benefit, called a "Pension Restoration Benefit," which is measured by the difference between (i) the monthly benefit which would have been provided to the participant under the Defined Benefit Pension Plan as if there were no annual compensation limitation and no exclusion on nonqualified deferred compensation, and (ii) the monthly benefit to be provided to the participant under the Defined Benefit Pension Plan. At the current time, the Pension Restoration Benefit only applies to participants in the Pension Equalization Plan. It does not apply to participants in the 2007 Pension Equalization Plan.

NONQUALIFIED DEFERRED COMPENSATION FOR 2007

        We have a Nonqualified Deferred Compensation Plan for a select group of management or highly compensated employees. The aggregate plan earnings for 2007 and the aggregate balance as of December 31, 2007 for our Named Executive Officers are shown in the following table. Our Named Executive Officers made no contributions and received no withdrawals or distribution from the plan in 2007. In addition, we made no contributions to the plan in 2007.

(1)

No contributions were made by the Named Executive Officers in 2006 or 2007 and none of the earnings met the definition of above-market or preferential earnings, therefore none of these amounts are included in the Summary Compensation Table.

        Eligibility to participate in the plan is determined by the Compensation Committee and currently consists of only corporate officers. Eligible employees may elect to defer up to 50 percent of their base salary, up to 100 percent of their Short-Term Annual Incentive Plan award, including Company stock, and elect to defer restricted stock grants in the form of restricted stock units. The deferrals are deposited into a trust account where the participants may direct the investment of the deferrals (except for Company stock and restricted stock unit deferrals) as allowed by the plan. The investment options are the same as those offered to all employees in the 401(k) Plan except for a fixed rate option which was set at 5.6 percent in 2007. Investment earnings are credited to the participants' accounts. Upon retirement, we will distribute the account balance to the participant according to the distribution election filed with the Compensation Committee. The participants may elect either a lump sum payment to be paid within 30 days of retirement (requires a six month deferral for benefits not vested as of December 31, 2004), or annual or monthly installments over a period of years designated by the participant, but not to exceed 15 years.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

        The following table describes the potential payments and benefits under our compensation and benefit plans and arrangements to which our Named Executive Officers would be entitled upon termination of employment. Except for certain terminations following a change in control of the Company, as described below; pro-rata payout of incentive compensation and the acceleration of vesting of equity awards upon retirement, death or disability; and certain pension and nonqualified deferred compensation arrangements described under Pension Benefits for 2007 and Nonqualified Deferred Compensation for 2007 above, there are no agreements, arrangements or plans that entitle the Named Executive Officers to severance, perquisites, or other enhanced benefits upon termination of their employment. Any agreement to provide such other payments or benefits to a terminating executive officer would be in the discretion of the Compensation Committee.

        The amounts shown below assume that such termination was effective as of December 31, 2007, and thus include estimates of the amounts which would be paid out to our Named Executive Officers upon their termination. The table does not include amounts such as base salary, short-term incentives and stock awards which the Named Executive Officers earned due to employment through December 31, 2007 and distributions of vested benefits such as those described under Pension Benefits

32

---

for 2007, Nonqualified Deferred Compensation for 2007 and vested stock options listed in the Outstanding Equity Awards at Fiscal Year-End 2007 tables. The table also does not include a value for outplacement services because this would be a diminimus amount. The actual amounts to be paid out can only be determined at the time of such Named Executive Officer's separation from the Company.

(1)

The amounts reflected for involuntary or good reason termination after a change in control include the benefits a Named Executive Officer would receive in the event of a change in control as a sole event without the involuntary or good reason termination.

(2)

Assumes that in the event of a change in control, Mr. Emery will receive an additional three years of credited and vesting service and the other Named Executive Officers will receive an additional two years of credited and vesting service towards the benefit accrual under the Defined Benefit Pension Plan, Pension Restoration Benefit, Pension Equalization Plan and 2007 Pension Equalization Plan. Assumes that each Named Executive Officer's pension compensation for the additional years of credited service is equal to the highest rate of salary earned in the one year period prior to the change in control.

(3)

Welfare benefits include medical coverage, dental coverage, life insurance, short-term disability coverage and long-term disability coverage. The calculation assumes that the Named Executive Officer does not take employment with another employer following termination and that the Named Executive Officer elects

33

---

continued welfare benefits until retirement and retiree medical benefits thereafter. Retirement is assumed to occur at age 65 for all the Named Executive Officers except Mr. Ohlmacher for which we have assumed retirement will occur at age 62 because he is already retiree eligible (see Note 6 to this table).

(4)

In the event of retirement, death or disability, the acceleration of equity awards represents the acceleration of unvested restricted stock, the payout of the pro-rata share of the performance shares calculated at target levels for the January 1, 2006 to December 31, 2008 and January 1, 2007 to December 31, 2009 performance periods.

In the event of a change in control or an involuntary or good reason termination after a change in control, the acceleration of equity awards represents the acceleration of unvested restricted stock, the payout of the pro-rata share of the performance shares calculated as if the performance period ended on December 31, 2007 for the January 1, 2006 to December 31, 2008 and January 1, 2007 to December 31, 2009 performance periods.


The valuation of the restricted stock was based upon the closing price of our common stock on December 31, 2007 and the valuation of the performance shares was based on the average closing price of our common stock for the last 20 trading days of 2007. Actual amounts to be paid out at the time of separation from the Company may vary significantly based upon the market value of our common stock at that time.

(5)

The calculation of the excise tax and gross-up amount is based on the Internal Revenue Code Section 4999 excise tax rate of 20 percent, a 35 percent federal income tax rate, a 1.45 percent Medicare tax rate and a 4.63 percent Colorado state income tax rate that applies to Mr. Ohlmacher only.

(6)

Because Mr. Ohlmacher is age 56, he is already retiree eligible. Therefore, in the event of a change in control he can begin receiving pension benefits on an undiscounted basis at age 62. The calculations assume he will continue to receive active welfare benefits until age 62 and that he will begin receiving pension benefits at that time. The other Named Executive Officers are not retiree eligible, therefore the calculations assume they will continue to receive active welfare benefits until age 65 and that they will begin receiving pension benefits at that time.

        Payments Made Upon Termination.    Regardless of the manner in which a Named Executive Officer's employment terminates, he may be entitled to receive amounts earned during his term of employment. These include:

•

accrued salary and unused vacation pay;



•

amounts vested under the Defined Benefit Pension Plan, Pension Equalization Plan, 2007 Pension Equalization Plan and the Pension Restoration Benefit;



•

amounts vested under the Nonqualified Deferred Compensation Plan; and



•

amounts vested under the 401(k) Retirement Savings Plan.

        Payments Made Upon Retirement, Death or Disability.    In the event of retirement, death or disability of a Named Executive Officer, in addition to the items identified above, he will also receive the benefit of the following:

•

accelerated vesting of unvested stock options;



•

accelerated vesting of restricted stock and restricted stock units;



•

a pro-rata share of the performance shares for each outstanding performance period upon completion of the performance period; and



•

a pro-rata share of the Short-Term Annual Incentive Plan upon completion of the annual incentive period.

        Payments Made Upon a Change in Control.    Our Named Executive Officers have change in control agreements that terminate June 1, 2008. The renewal of the change in control agreements is at the discretion of the Compensation Committee and the Board of Directors. The Compensation Committee

34

---

is conducting a thorough review of the agreements before the June 1, 2008 termination date. The change in control agreements provide for certain payments and other benefits to be payable upon a change in control and a subsequent termination of employment, either involuntary or for a good reason.

        A change in control is defined in the agreements as:

•

an acquisition of 30 percent or more of our common stock, except for certain defined acquisitions, such as acquisition by employee benefit plans, us, any of our subsidiaries, or acquisition by an underwriter holding the securities in connection with a public offering thereof; or



•

members of our incumbent Board of Directors at the time the agreements were executed cease to constitute at least two-thirds of the members of the Board of Directors, with the incumbent Board of Directors being defined as those individuals consisting of the Board of Directors on the date the agreement was executed and any other directors elected subsequently whose election was approved by the incumbent Board of Directors; or



•

approval by our shareholders of:



•

a merger, consolidation, or reorganization;



•

liquidation or dissolution; or



•

an agreement for sale or other disposition of 50 percent or more of our assets, with exceptions for transactions which do not involve an effective change in control of voting securities or Board of Directors membership, and transfers to subsidiaries or sale of subsidiaries; and



•

all regulatory approvals required to effect a change in control have been obtained and the transaction constituting the change in control has been consummated.

        In the change in control agreements, a good reason for termination which would trigger payment of benefits is defined to include:

•

a material reduction of the executive's authority, duties or responsibilities;



•

a reduction in the executive's annual compensation or any failure to pay the executive any compensation or benefits to which he or she is entitled within seven days of the date due;



•

any material breach by us of any provisions of the change in control agreement;



•

requiring the executive to be based outside a 50-mile radius from his or her usual and normal place of work; or



•

our failure to obtain an agreement, satisfactory to the executive, from any successor company to assume and agree to perform the change in control agreement.

        Upon a change in control, the CEO will have an employment contract for a three-year period and the non-CEO executive will have an employment contract for a two-year period, but not beyond age 65 ("employment term"). During this employment term, the executive shall receive annual compensation at least equal to the highest rate in effect at any time during the one-year period preceding the change in control and shall also receive employment welfare benefits, pension benefits, and supplemental retirement benefits on a basis no less favorable than those received prior to the change in control. Annual compensation is defined to include amounts which are includable in the gross income of the executive for federal income tax purposes, including base salary, targeted annual incentive bonus, targeted long-term incentive grants and awards; and matching contributions or other benefits payable

35

---

under the 401(k) Retirement Savings Plan; but exclude restricted stock awards, performance units or stock options that become vested or exercisable pursuant to a change in control.

        If a Named Executive Officer's employment is terminated prior to the end of the employment term by the Company for cause or disability, by reason of the Named Executive Officer's death, or by the Named Executive Officer without good reason, the Named Executive Officer will receive all amounts of compensation earned or accrued through the termination date. If the Named Executive Officer's employment is terminated because of death or disability, the Named Executive Officer or his beneficiaries will also receive a pro rata bonus equal to 100 percent of the target bonus for the portion of the year served.

        If the CEO's employment is terminated during the employment term (other than by reason of death) (i) by the Company other than for cause or disability, (ii) by the CEO for a good reason, or (iii) by the CEO for any reason during a 30-day window period immediately following the first anniversary of a change in control, then the CEO is entitled to the following benefits:

•

all accrued compensation and a pro rata bonus (the same as the CEO or the CEO's beneficiaries would receive in the event of death or disability discussed above);



•

severance pay equal to 2.99 times the CEO's five-year average severance compensation defined as the CEO's base salary and annual incentive payment plus any discretionary bonuses paid in cash or vested stock on a calendar-year basis; provided that if the CEO has attained the age of 62 on the termination date, the severance payment shall be adjusted for the ratio of the number of days remaining to the CEO's 65^th birthday to 1,095 days;



•

continuation of employee welfare benefits for three years following the termination date unless the CEO becomes covered under the health insurance coverage of a subsequent employer which does not contain any exclusion or limitation with respect to any preexisting condition of the CEO or the CEO's eligible dependents;



•

following the three-year period, the CEO may elect to receive coverage under the employee welfare plans of the successor entity at his then-current level of benefits (or reduced coverage at the CEO's election) by paying the premiums charged to regular full-time employees for such coverage, and is eligible to continue receiving such coverage through the date of his retirement;



•

coverage under the successor entity's retiree health insurance coverage if the CEO elected the continuation of employee welfare plan coverage through the date of his retirement;



•

three years of additional credited service under the Pension Equalization Plan and Defined Benefit Pension Plan; and



•

outplacement assistance services for up to six months.

        If the non-CEO executive's employment is terminated during the employment term (other than by death) (i) by the Company other than for cause or disability, or (ii) by the non-CEO for a good reason; then the non-CEO is entitled to the following benefits:

•

all accrued compensation and a pro rata bonus (the same as the non-CEO or the non-CEO's beneficiaries would receive in the event of death or disability discussed above);



•

severance pay equal to two times the non-CEO's five-year average severance compensation defined as the non-CEO's base salary and annual incentive payment plus any discretionary bonuses paid in cash or vested stock on a calendar-year basis; provided that if the non-CEO has attained the age of 63 on the termination date, the severance payment shall be adjusted for the ratio of the number of days remaining to the non-CEO's 65^th birthday to 730 days;

36

---

•

continuation of employee welfare benefits for two years following the termination date unless the non-CEO becomes covered under the health insurance coverage of a subsequent employer which does not contain any exclusion or limitation with respect to any preexisting condition of the non-CEO or the non-CEO's eligible dependents;



•

following the two-year period, the non-CEO may elect to receive coverage under the employee welfare plans of the successor entity at his then-current level of benefits (or reduced coverage at the non-CEO's election) by paying the premiums charged to regular full-time employees for such coverage, and is eligible to continue receiving such coverage through the date of his retirement;



•

coverage under the successor entity's retiree health insurance coverage if the non-CEO elected the continuation of employee welfare plan coverage through the date of his retirement;



•

two years of additional credited service under the Pension Equalization Plan or 2007 Pension Equalization Plan and the Defined Benefit Pension Plan; and



•

outplacement assistance services for up to six months.

        The change in control agreements contain an additional benefit to cover any excise tax imposed by Section 4999 of the Internal Revenue Code of 1986. The executive must sign a waiver and release agreement in order to receive the severance payment.

SEVERANCE AGREEMENT

        Effective January 18, 2008, we entered into a Severance and Release Agreement with Mark T. Thies, whose resignation from the Company occurred on that date. The agreement provides for payment of a severance amount of $350,000, reimbursement of COBRA premium cost of continued healthcare coverage for a period of twelve months and outplacement assistance.

All of our directors have currently met their stock ownership guidelines.

(1)

Our directors did not receive any option awards, non-equity incentive plan compensation, pension benefits or perquisites in 2007.

(2)

Mr. Emery, our CEO, is not included in this table as he is an employee of the Company and thus receives no compensation for his services as a director. Mr. Emery's compensation received as an employee is shown in the Summary Compensation Table for our Named Executive Officers.

(3)

Each non-employee director received a quarterly award of common stock equivalents with a grant date fair value of $9,000 a quarter or $36,000 a year.

(4)

The common stock equivalents are fully vested in that they are not subject to forfeiture; however, the shares are not issued until after the director ends his or her service on the Board. The common stock equivalents are payable in stock or cash or can be deferred further at the election of the director.

(5)

Mr. Korpan did not seek reelection and resigned as a member of our Board of Directors effective May 22, 2007, consequently his fees earned and stock award fair value reflect a partial year of service.

(6)

Mr. Robinson and Mr. Pechota became members of our Board of Directors effective April 1, 2007 and May 22, 2007, respectively, consequently their fees earned and stock award fair values reflect partial years of service.

Proposal 3

SHAREHOLDER PROPOSAL

        Gerald R. Armstrong, the holder of approximately 724 shares of the Company's common stock, whose address is 820 Sixteenth Street, No. 705, Denver, Colorado, 80202-3227, has notified the Company that he intends to present the following resolution at the Annual Meeting. If properly presented, this resolution will be voted on at the Annual Meeting. The Board of Directors and the Company accept no responsibility for the proposed resolution and supporting statement. As required by federal regulations, the resolution and supporting statement are printed below.

SHAREHOLDER RESOLUTION:

        That the shareholders of Black Hills Corporation request its Board of Directors to take the steps necessary to eliminate classification of terms of its Board of Directors to require that all Directors stand for election annually. The Board declassification shall be completed in a manner that does not affect the unexpired terms of the previously-elected Directors.

Shareholder Supporting Statement:

        The proponent believes that the election of directors is the strongest way that shareholders influence the directors of any corporation. Currently, our Board of Directors is divided into three classes with each class serving three-year terms. Because of this structure, shareholders may only vote

42

---

for one-third of the directors each year. This is not in the best interest of shareholders because it reduces accountability.

        U.S. Bancorp, Associated Banc-Corp, Piper-Jaffray Companies, Fifth-Third Bancorp, Pan Pacific Retail Properties, Qwest Communications International, Xcel Energy, Greater Bay Bancorp, North Valley Bancorp, Pacific Continental Corporation, Regions Financial Corporation, CoBiz Financial Inc., Marshall & Illsley Corporation, and Wintrust Financial, Inc. are among the corporations electing directors annually because of the efforts of the proponent.

        The performance of our management and our Board of Directors is now being more strongly tested due to economic conditions and the accountability for performance must be given to the shareholders whose capital has been entrusted in the form of share investments.

        A study by researchers at Harvard Business School and the University of Pennsylvania's Wharton School titled "Corporation Governance and Equity Prices" (Quarterly Journal of Economics, February 2003), looked at the relationship between corporate governance practices (including classified boards) and firm performance. The study found a significant positive link between governance practices favoring shareholders (such as annual directors election) and firm value.

        While management may argue that directors need and deserve continuity, management should become aware that continuity and tenure may be best assured when their performance as directors is exemplary and is deemed beneficial to the best interests of the corporation and its shareholders.

        The proponent regards as unfounded the concern expressed by some that annual election of all directors could leave companies without experienced directors in the event that all incumbents are voted out by shareholders. In the unlikely event that shareholders do vote to replace all directors, such a decision would express dissatisfaction with the incumbent directors and reflect a need for change.

        If you agree that shareholders may benefit from greater accountability afforded by annual election of all directors, please vote "FOR" this proposal.

BOARD OF DIRECTORS' STATEMENT IN OPPOSITION:

        In response to the shareholder proposal, the Board of Directors performed a thorough review of our company's classified board structure. The matter was considered by our Governance Committee and the Board of Directors. Our review included consideration of the reasons why companies choose to classify their boards, such as the need for continuity and protection against coercive takeover tactics. It also included consideration of the provisions of our Articles of Incorporation and Bylaws, and in particular, the existing cumulative voting provisions.

        After thorough consideration of the classified board issue, the Board of Directors ultimately determined that it is in the best interest of the shareholders to retain the classified board. We agree that corporate governance measures have a bearing upon company performance and accountability to shareholders. We do not agree that the efficacy of governance factors, however, should be viewed in isolation. Rather, it is the entire complex of corporate governance measures implemented by a specific company that should guide the evaluation of shareholder value and accountability. This is the approach applied by institutional shareholder organizations that publish annual corporate governance ratings. According to these measures, even with a classified Board of Directors, Black Hills Corporation has garnered corporate governance ratings that consistently outperform utility companies and companies in the S&P 400 Index. As reflected in our rating, our Board has in place governance guidelines that enhance corporate accountability, such as measures to assure that the Board is composed of a majority of independent directors, and that only independent directors are members of its committees. The Board believes that a director's contributions are best measured over several years, versus the short-term evaluation implicit in annual elections.

        Moreover, Black Hills Corporation does not have a poison pill in place to deter hostile takeover attempts. The classified board structure, therefore, provides important protection for directors against pressure from special interest groups who might have an agenda contrary to the long-term interests of all our shareholders. We feel that all directors must be concerned about the interests of all of the shareholders, as opposed to the issues asserted by a special interest constituency. The classified board structure enhances the Board's ability to negotiate with a suitor to obtain the best result for shareholders in a takeover event, and thus gives us the leverage required to best fulfill our fiduciary responsibilities in responding to a possible takeover.

        Our Board of Directors also believes that it is essential, in reviewing the classified board structure, to take into account the cumulative voting provisions in our Articles of Incorporation and the impact of those provisions with or without classification of the Board. Our Articles of Incorporation provide for cumulative voting which, when coupled with an annual election of directors, would substantially multiply the ability of a shareholder with short-term objectives to elect a member or members of the Board. Notably, most of the companies which have eliminated classified board structures do not have cumulative voting. Because a classified board can make it more difficult for third parties with short-term objectives to seize control of the Company in a single proxy contest, the classified board system provides the leverage needed under coercive conditions to negotiate terms that will maximize the value of the Company for all shareholders.

        Finally, although this proposal disputes the value of director continuity, we feel that there simply is no substitute for the classified board structure in providing experience and perspective to facilitate long-term planning, and to maximize the value of the Company for our long-term investors. Our classified Board assures that a majority of directors at any time will have the prior experience and knowledge to oversee our complex business, with two classes of directors always having served for one or more years. Although we believe board continuity is important, our use of a classified board has not enabled directors to become "entrenched," or unresponsive to shareholders. Even with a classified structure, our shareholders have had the opportunity to elect 12 new directors in the last 10 years, who have applied new perspectives and experience to our implementation of a long-term strategy.

        The Board endeavors always to act in a manner that reflects its judgment of the best interests of the Company and its shareholders and does not believe that the classified board structure undermines or affects in any way the accountability of the Board. All directors are required to uphold their fiduciary duties to our Company and its shareholders regardless of their term of office. A classified board permits shareholders to annually change one-third of the directors and thereby substantially change the Board's composition and character. Corporate accountability, in our view, is best served by the selection of responsible and experienced individuals, and not by potentially limiting director terms to one year instead of three.

        The Board of Directors of Black Hills Corporation is committed to excellence in corporate governance and enhancement of shareholder value. We believe that our existing record demonstrates that we will use the classified board for its intended purpose, which is to enable us to best fulfill our fiduciary responsibilities to the shareholders. At the 1986 Annual Meeting, a substantial majority of our shareholders (79 percent of shareholders voting) voted to approve the Board's recommendation to adopt a classified Board. The Board continues to believe that the present system of electing one-third of the Board each year offers important advantages to our shareholders, is in the best interests of the Company and should not be changed.
