Proxy Statement Questions and Answers

     
1. Q:   Why am I receiving these materials?
     
A:   The Board of Directors of Otter Tail Corporation provides these proxy materials for use at the Annual Meeting of Shareholders to be held on April 12, 2004. As a shareholder you are invited to attend the annual meeting and are entitled to vote on the proposals described in this proxy statement. These materials were sent to shareholders on or about March 17, 2004.
     
2. Q:   Who is entitled to vote at the annual meeting?
     
A:   Only common shareholders of record at the close of business on February 13, 2004 are entitled to vote at the annual meeting. As of the record date, 25,781,402 common shares of Otter Tail Corporation were issued and outstanding. Each shareholder is entitled to one vote per share.
     
3. Q:   What issues may I vote on at the annual meeting?
     
A:   You may vote on the election of three nominees to serve on the Board of Directors, to ratify Deloitte & Touche LLP as independent auditors for 2004, and on any other business that is properly brought before the meeting.
     
4. Q:   How do I vote my shares?
     
A:   You may vote either in person at the annual meeting or by granting a proxy. If you desire to grant a proxy, then you have three voting options:

    by telephone
 
    by Internet
 
    by proxy card
     
    If you intend to vote by proxy, please refer to the instructions included on your proxy card. Voting by proxy will not affect your right to vote your shares if you attend the annual meeting and desire to vote in person.
     
5. Q:   May I change my vote?
     
A:   You have the right to revoke your proxy any time before the annual meeting by:

    Providing written notice to an officer of Otter Tail Corporation and voting in person at the annual meeting.
 
    Submitting another proper proxy by telephone or the Internet.
 
    Submitting a new written proxy bearing a later date at any time before the proxy is voted at the meeting.
     
6. Q:   How are the votes counted?
     
A:   In the election of Directors, you may vote FOR all of the nominees or your vote may be WITHHELD with respect to one or more nominees. If you return your signed proxy card, but do not mark the boxes showing how you wish to vote, your shares will be voted FOR all nominees, and FOR the appointment of Deloitte & Touche LLP as independent auditors.
     
    Shares voted as abstentions on any matter (or as “withhold authority” as to Directors) will be counted as shares that are present and entitled to vote for purposes of determining the presence of a quorum at the meeting and as unvoted, although present and entitled to vote, for purposes of determining the approval of each matter as to which the shareholder has abstained.
     
    If a broker submits a proxy that indicates that the broker does not have discretionary authority as to certain shares to vote on one or more matters, those shares will be counted as shares that are present and entitled to vote for purposes of determining the presence of a quorum at the meeting, but will not be considered as present and entitled to vote with respect to such matters.

The affirmative vote of a majority of the common shares present and entitled to vote with respect to the election of Directors is required for the election of the nominees to the Board of Directors. The proxies solicited may be voted for a substitute nominee or nominees in the event that any of the nominees is unable to serve, or for good reason will not serve, which is a contingency not now anticipated.

These biographies include the ages of the Directors (as of the 2004 Annual Meeting of Shareholders) and outlines of their business experiences.

Meetings and Committees of the Board

The full Board of Directors of Otter Tail Corporation considers all major decisions of Otter Tail Corporation. The Board has established a standing Audit Committee, Compensation Committee, Corporate Governance Committee, and Executive Committee so that certain important matters can be addressed in more depth than may be possible in a full Board meeting. Committee charters can be found on the Otter Tail Corporation website at www.ottertail.com.

The full Board of Directors held a total of seven regularly scheduled and special meetings in 2003. The Board of Directors also held a planning retreat with senior management. In conjunction with each meeting and the retreat, the Board of Directors met in executive session without management present. Each incumbent Director attended all meetings of the Board of Directors held during the period for which he was a Director and all meetings of the committees during the periods he served on such committees. Each then-incumbent Director attended the Annual Meeting of Shareholders in 2003. The Corporation expects that all Directors and executive officers will attend the Annual Meeting of Shareholders.

Audit Committee

The Audit Committee reviews financial results of Otter Tail Corporation, reviews accounting, audit and control procedures, and retains and supervises the outside independent public accountants. The Audit Committee has oversight responsibility for the Corporation’s Code of Conduct. This committee is composed of six members of the Board of Directors who, for 2003, were Dennis R. Emmen, Kenneth L. Nelson, Nathan I. Partain, Gary J. Spies, and Robert N. Spolum. In 2004, Karen M. Bohn joined the committee. All committee members are independent as defined by the NASDAQ Listing Standards. The Board has determined that Mr. Emmen, Mr. Partain, and Mr. Spolum meet the SEC definition for financial expert and all remaining members of the Committee are financially literate. This committee held five meetings in 2003. For further information on the actions of the Audit Committee, please refer to the Report of the Audit Committee on page 17. A copy of the Audit Committee charter is attached as Appendix 1.

Compensation Committee

The Compensation Committee reviews, approves, and reports to the Board on compensation programs and benefit plan matters involving the Corporation’s Directors and executive officers. The Compensation Committee oversees the administration of the 1999 Employee Stock Purchase Plan and the 1999 Stock Incentive Plan. Working with an outside compensation consultant, and subject to approval by the Board, this committee sets compensation for the Directors, the Chief Executive Officer, and certain executive officers. This committee is composed of four members of the Board of Directors who, for 2003, were Thomas M. Brown, Dennis R. Emmen, Maynard D. Helgaas, and Arvid R. Liebe, and all of whom are independent Directors, consistent with the NASDAQ Listing Standards. The committee held five meetings in 2003. For further information on the actions of the Compensation Committee, please refer to the Report of the Compensation Committee on page 9.

Corporate Governance Committee

The Corporate Governance Committee provides recommendations to the Board on candidates for election as Directors, on Director committee assignments, on actions necessary for the proper governance of Otter Tail Corporation, and on actions necessary for the evaluation of the performance of the Board of Directors and Chief Executive Officer. With input from the Chief Executive Officer, the committee recommends certain executive officers for annual election. The committee reviews, as necessary, changes in corporate governance required by statute or rule and makes recommendations to the Board on changes in structure, rule or practice necessary for compliance and for good corporate governance. The Board of Directors has not set minimum standards for Director candidates. Rather, it seeks highly qualified individuals with a wide variety of business and life experiences that will enable them to constructively review and guide management of Otter Tail Corporation. Otter Tail Corporation has successfully obtained highly qualified candidates for Directors without utilizing a paid outside consultant. Any shareholder may submit a recommendation for nomination to the Board of Directors by sending a written statement of the qualifications of the recommended individual to the President and Chief Executive Officer, Otter Tail Corporation, Box 496, Fergus Falls, Minnesota 56538-0496. Such nominations will be given due consideration by the Corporate Governance Committee. The Corporate Governance Committee is composed of four members of the Board of Directors who, for 2003, were Thomas M. Brown, Maynard D. Helgaas, Nathan I. Partain, and Gary J. Spies, all of

This committee is composed of four members of the Board of Directors who, for 2003, were Arvid R. Liebe, John C. MacFarlane, Nathan I. Partain, and Robert N. Spolum. This committee did not meet in 2003.

Director Compensation

All Directors of Otter Tail Corporation receive an annual retainer for their services as a Director, including service on committees. All Directors, except the Chairman, receive an annual retainer of $24,000. The Chairman receives an annual retainer of $60,000. All Directors receive a fee of $1,000 for attendance at each board and committee meeting. Each committee chair receives an additional retainer of $3,000 per year. In addition, Directors receive an actual expense or a $100 travel allowance if they are required to furnish their own transportation to board or committee meetings outside their city of residence.

In 2003, each Director received 1,300 shares of restricted stock, granted under the terms of the 1999 Stock Incentive Plan. The shares of restricted stock, which were granted on the date of the annual meeting, vest over a period of four years, at the rate of 25% per year, and are eligible for full dividend and voting rights.

Directors may elect to receive their compensation (other than expense reimbursements) in the form of cash, stock or a combination. Directors may elect to defer the receipt of all or part of their cash compensation pursuant to the Otter Tail Corporation Deferred Compensation Plan for Directors. The deferral may be in the form of cash or stock units. Cash deferrals receive interest at a rate equal to 1% over the prime commercial rate of U.S. Bank National Association. Deferrals in the form of stock units are credited quarterly with dividend equivalents equal to the dividend rate on the Otter Tail Corporation’s Common Stock and the deferred amount is paid out in shares of common stock.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires Otter Tail Corporation’s Directors and certain executive officers and holders of more than 10 percent of Otter Tail Corporation’s common shares to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of common shares and other equity securities of Otter Tail Corporation. Otter Tail Corporation believes that during the year ended December 31, 2003 its Directors and executive officers complied with all Section 16(a) filing requirements.

Executive Compensation

Compensation Committee Report on Executive Compensation

The Compensation Committee of the Board of Directors is composed solely of independent Directors as defined by the NASDAQ Listing Standards, and operates under a written charter adopted by the Board of Directors. This committee is responsible for developing Otter Tail Corporation’s executive compensation program for Mr. Erickson, Mr. Molbert, Mr. Moug, and Mr. Koeck (referred to in this report as the “executive officers”) and recommending it to the Board of Directors. The components of the executive compensation program are base salary, annual incentive bonus, and long-term incentive in the form of restricted stock.

Working with an outside compensation consultant (Towers Perrin), the Compensation Committee develops annual recommendations

Table of Contents

for compensation for the Chief Executive Officer and the other executive officers. Towers Perrin prepared 2003 market-based compensation data at the 25th, 50th, and 75th percentiles for the four top management positions of Otter Tail Corporation, providing information on base salary, annual bonus, and total direct compensation. Towers Perrin based its report on general industry data for companies of comparable revenues because of the diversified operations of Otter Tail Corporation and the resulting skills required of its executive officers. Otter Tail Corporation utilized the 50th percentile as the midpoint for base salary, annual bonus, long-term incentives, and total direct compensation for each executive officer.

Compensation for Mr. C. MacFarlane was set by the Executive Vice President and Chief Operating Officer because Mr. C. MacFarlane is not elected to his position by the Board of Directors.

Base Salary

The Chief Executive Officer makes specific recommendations to the Compensation Committee with respect to adjustments in base salary for executive officers (other than himself) based upon the market data and analysis described above and other factors, which typically are subjective and reflect individual performances during the year or changes in corporate responsibilities. The Compensation Committee reviews the recommendations of the Chief Executive Officer for consistency with the market data. The committee may adjust base salaries, however, as it sees fit without respect to the market data or any other objective criteria. For 2003, base salary for each executive officer was below the midpoint of the market data.

Annual Incentive Bonus

The Compensation Committee utilizes an incentive bonus plan for Otter Tail Corporation’s executive officers. The Otter Tail Corporation Management Incentive Plan provides incentives to these officers if Otter Tail Corporation achieves certain performance targets. The annual incentive bonus is designed to place a significant portion of each executive officer’s annual cash compensation “at risk” depending upon the financial performance of Otter Tail Corporation for that year. The Compensation Committee is responsible for setting performance targets near the end of the first quarter each year and establishes total target payout percentages for each of these officers. For 2003, the target payouts were set below the midpoint of the market data and the performance targets were as follows:

1.   Corporate earnings per share. Each officer receives 25 percent of the total target payout if Otter Tail Corporation achieves the targeted earnings per share. Each officer receives 12 ½ percent of the total target payout if Otter Tail Corporation achieves the minimum performance level, and additional increments for performance above the target. Otter Tail Corporation did not meet the minimum performance level for earnings per share in 2003.
 
2.   Corporate return on equity. Each officer receives 25 percent of the total target payout if Otter Tail Corporation achieves the targeted return on equity. Each officer receives 12 ½ percent of the total target payout if Otter Tail Corporation achieves the minimum performance level, and additional increments for performance above the target. Otter Tail Corporation did not meet the minimum performance level for return on equity in 2003.
 
3.   Electric utility net income. Each officer receives 25 percent of the total target payout if the electric utility achieves its targeted net income. Each officer receives 12 ½ percent of the total target payout if the electric utility achieves the minimum performance level and additional increments up to 200% of the target payout for performance above the target. Electric utility net income reached the maximum performance level in 2003.

4.   Nonelectric return on capital. Each officer receives 25 percent of the total target payout if the nonelectric operations of the Corporation achieve its targeted return on capital. Each officer receives 12 ½ percent of the total target payout if the nonelectric operations achieve the minimum performance level. Each officer receives up to 175 percent of the total target payout if the nonelectric operations exceed its targeted performance level for return on capital. Otter Tail Corporation did not meet the minimum performance level for nonelectric operations return on capital in 2003.

The Compensation Committee has discretion over treatment of extraordinary gains, writeoffs, or other events in determining the amount of incentive bonus to be paid. All incentive payments for 2003 were based upon reported results. Mr. Erickson and Mr. Molbert each declined 50% of the 2003 annual incentive bonus.

Long-term Incentives

Long-term incentive compensation for executive officers is based on restricted stock awards granted by the Compensation Committee under Otter Tail Corporation’s 1999 Stock Incentive Plan. The Stock Incentive Plan is designed to attract and retain employees, officers, and nonemployee Directors capable of assuring Otter Tail Corporation’s future success. The plan is also designed to align the interests of executive officers with shareholders. The Board of Directors has designated the Compensation Committee to administer the plan.

In 2003 the Compensation Committee awarded restricted stock grants for 76,200 common shares to the executive officers as a group. The size of the grant awarded to each executive officer was intended to be competitive with awards to officers in similar positions in comparable companies, based on market data provided by Towers Perrin for the 50th percentile of long-term incentives and the 50th percentile of total direct compensation.

The committee also considered other criteria, such as years of service and individual performance. For 2003, the value of the long-term incentive compensation award to each executive officer was below the midpoint of the market data. The restricted shares vest at a rate of 25% per year provided the executive officer remains employed by Otter Tail Corporation.

Chief Executive Officer Compensation

The Board of Directors, upon the Compensation Committee’s recommendation, sets the Chief Executive Officer’s base salary. The committee determines the Chief Executive Officer’s base salary utilizing the same criteria as it utilizes to determine the base salaries for the other executive officers, but without recommendation from the Chief Executive Officer. The committee determines the Chief Executive Officer’s annual incentive bonus, if any, in the same manner that it determines the bonus of the other executive officers. In 2003, the committee granted the Chief Executive Officer an award of shares of restricted stock of 36,000 common shares, based on the same criteria as the grants to the other executive officers.

Section 162(m) of the Internal Revenue Code

Section 162(m) of the Internal Revenue Code imposes limits on tax deductions for executive compensation in excess of $1 million paid to any of the top five executive officers named in the Summary Compensation Table. It is the committee’s policy to take reasonable steps to preserve this tax deduction.

(1)   Each option was granted with a term of ten years and becomes exercisable as to 25% of the common shares covered thereby on each of the first through fourth anniversaries of the grant date. All options become fully exercisable upon a change of control. The exercise price may be paid by delivery of common shares, and tax withholding obligations related to exercise may be paid by delivery or withholding of common shares.
 
(2)   In accordance with Securities and Exchange Commission Rules, the Black-Scholes option pricing model was chosen to estimate the grant date present value of the options set forth in this table. Otter Tail Corporation’s use of this model should not be construed as an endorsement of its accuracy at valuing options. All stock option valuation models, including the Black-Scholes model, require a prediction about the future movement of the stock price. The following assumptions were made for the purpose of calculating the grant date present value for the options granted: expected life of the option of seven years, volatility at 26.28%, dividend yield of 4.00% and discount rate of 3.659%.

A participant’s final average earnings for those officers in the Corporate Group (Mr. Erickson, Mr. Molbert, Mr. Moug and Mr. Koeck) is determined using the 42 consecutive months out of the last 10 consecutive years prior to the participant’s retirement which produces the highest average salary (Table 1). As a nonunion utility participant, Mr. C. MacFarlane’s final average earnings is determined using the 30 consecutive months out of the last 10 consecutive years (Table 2). As of December 31, 2003, the annual final average earnings and actual credited years of service for each of the officers were as follows: Mr. Erickson, $287,393 (23 years), Mr. C. MacFarlane, $179,060 (2 years), Mr. Molbert, $268,750 (2 years), Mr. Moug, $221,250 (2 years), Mr. Koeck, $180,372 (4 years).

The benefits in the foregoing table were calculated as a straight life annuity. Because covered compensation takes into account an average of annual Social Security benefits, there is no deduction for Social Security under the pension plan. The amounts shown in the tables on page 14 reflect the limits imposed by Sections 415 or 401(a)(17) of the Internal Revenue Code.

Otter Tail Corporation maintains the Executive Survivor and Supplemental Retirement Plan, which was amended and restated effective January 1, 2002. This plan is designed to provide survivor and retirement benefits for certain executive officers and other key management employees in order to attract and retain employees of outstanding competence. Each of the officers in the Summary Compensation Table is a participant in this plan. If a participant who is deemed to be an executive officer under the plan dies while employed by Otter Tail Corporation, Otter Tail Corporation will pay the participant’s beneficiary an amount equal to four times the participant’s annual salary and bonus at the time of death. If an executive officer under the plan dies after retirement or dies after termination for other reasons with a vested benefit, Otter Tail Corporation will pay the executive’s beneficiary a lesser amount, depending on the participant’s age at death and his or her vested percentage.

In addition to these survivor benefits, the Executive Survivor and Supplemental Retirement Plan provides retirement benefits to Mr. Erickson and Mr. Koeck, equal to 70% of the executive’s salary and bonuses during the 12 months before retirement offset by the executive officer’s Social Security benefit and the amount of the executive officer’s benefit from Otter Tail Corporation’s qualified pension plan if it were paid in the form of a single life annuity. The retirement benefit is paid in the form of a 15-year certain or life annuity or a 50% joint and survivor annuity. The benefit vests over five years. Mr. Koeck’s benefit amount accrues over a 15-year period beginning with his date of hire.

Mr. Molbert, Mr. C. MacFarlane, and Mr. Moug are also participants in the Executive Survivor and Supplemental Retirement Plan. The benefit for Mr. C. MacFarlane, Mr. Molbert, Mr. Moug is equal to 65% of the executive’s Final Average Earnings as defined by the plan, with the same offsets as shown above. The benefit amount vests after five years of service under the plan, with the full benefit amount accruing over 15 years. The retirement benefit is paid in the form of a 15-year certain or life annuity or a 50% joint and survivor annuity.

All participants who retire early (after 10 years of service and age 55) or who terminate before retirement with a vested benefit in the plan will be paid a reduced amount. If a participant dies while still employed, his or her beneficiary will be paid the actuarial equivalent of the participant’s benefit in 15 annual installments. Upon a Change in Control as defined by the plan, or in the event of the death of the participant while actively employed by Otter Tail Corporation, the participant becomes

Table of Contents

100% vested in his or her accrued benefit. In the event of disability, Years of Credited Service and Years of Participation continue to accrue under the plan until such time as payments under Otter Tail Corporation’s Long Term Disability Plan end. At any time after a change in control or following termination of employment, a participant is entitled to receive upon request a lump sum distribution of 90% of his or her benefits in the plan with forfeiture of the remaining benefits.

The Board of Directors has the right to amend, suspend, or terminate the plan, but no such action can reduce the benefits already accrued. Otter Tail Corporation has purchased insurance on the lives of many of the participants to provide sufficient funding to satisfy the benefit obligations payable under this plan. The estimated annual benefits payable under the plan upon retirement at age 65 for each of the named officers, assuming salary is unchanged from 2003, and bonus determined by actuarial assumptions based on past financial performance, is as follows: Mr. Erickson, $172,350; Mr. Molbert, $99,375; Mr. Moug, $64,631; Mr. Koeck, $83,795; Mr. C. MacFarlane $78,205.

Severance and Employment Agreements

Otter Tail Corporation has entered into change of control severance agreements (the Severance Agreements) with Mr. Erickson, Mr. Molbert, Mr. Moug, and Mr. Koeck. The Severance Agreements provide for certain payments and other benefits if, following a Change in Control, Otter Tail Corporation terminates the officer’s employment without Cause or the officer terminates his employment for Good Reason. Such payments and benefits include: (i) severance pay equal to three times the sum of the officer’s salary (at the highest annual rate in effect during the three years prior to the termination) and average annual bonus (for the three years prior to the termination); (ii) three years of continued life, health and disability insurance; (iii) the payment of legal fees and expenses relating to the termination; (iv) the termination of any noncompetition arrangement between Otter Tail Corporation and the officer; and (v) a gross-up payment for any excise tax imposed on such payments or benefits and for any tax imposed on such gross-up. Under the Severance Agreements, “Cause” is defined as willful and continued failure to perform duties and obligations or willful misconduct materially injurious to Otter Tail Corporation; “Good Reason” is defined to include a change in the employee’s responsibility or status, a reduction in salary or benefits, or a mandatory relocation; and “Change in Control” is defined to include a change in control of the type required to be disclosed under Securities and Exchange Commission proxy rules, acquisition by a person or group of 35% of the outstanding voting stock of Otter Tail Corporation, a proxy fight or contested election which results in Continuing Directors (as defined) not constituting a majority of Otter Tail Corporation’s Board of Directors, or another event the majority of the Continuing Directors determines to be a change in control.

Report of Audit Committee

The Audit Committee of Otter Tail Corporation’s Board of Directors is composed of six independent Directors, as defined by NASDAQ Listing Standards, and operates under a written charter adopted by the Board of Directors. A copy of the Audit Committee charter is attached as Appendix 1. The Audit Committee retains and supervises Otter Tail Corporation’s independent accountants, currently Deloitte & Touche LLP, subject to shareholder ratification.

Management is responsible for Otter Tail Corporation’s internal controls and the financial reporting process. The independent accountants are responsible for performing an independent audit of Otter Tail Corporation’s consolidated financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes.

In this context, the Audit Committee met and held discussions with management and the independent accountants. Management represented to the Audit Committee that Otter Tail Corporation’s consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee reviewed and discussed the consolidated financial statements with management and the independent accountants. The Audit Committee discussed with the independent accountants matters required to be discussed by Statement on Auditing Standards No. 61 (Communications with Audit Committees).

Otter Tail Corporation’s independent accountants also provided to the Audit Committee the written disclosures required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and the Audit Committee discussed with the independent accountants that firm’s independence.

Based on the Audit Committee’s discussion with management and the independent accountants and the Audit Committee’s review of the representation of management and the report of the independent accountants to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in Otter Tail Corporation’s Annual Report on Form 10-K for the year ended December 31, 2003, filed with the Securities and Exchange Commission.

Pre-approval of Audit/Non-audit Services Policy

The Company’s Audit Committee has adopted, and the Board of Directors has ratified, the Audit and Non-Audit Services Pre-Approval Policy which sets forth the procedures and the conditions pursuant to which services proposed to be performed by the independent auditor may be pre-approved. The independent auditor has reviewed this policy and believes that implementation of the policy will not adversely affect the auditor’s independence.

Four categories of services have been defined by the Company within the policy:

Audit services are specified services directly related to performing the independent audit of Otter Tail Corporation and its subsidiaries. The Audit Firm will submit to the Audit Committee for pre-approval the scope and estimated fees associated with the current year audit at the July Audit Committee meeting.

Audit-related services are specified services that are related extensions of audit services and are logically performed by the auditors. Additional services exceeding the specified pre-approved limits require specific Audit Committee approval.

Tax services are specified services related to tax matters. Using the Audit Firm for these matters creates efficiencies, minimizes disruption, or preserves confidentiality. Additional services exceeding the specified pre-approved limits, or adding service types to the pre-approved list, requires specific Audit Committee approval.

Other services include (a) “synergistic” services for which utilizing the audit firm creates efficiencies, minimizes disruption, or preserves confidentiality, or (b) “unique

qualifications” services for which management has determined that the audit firm possesses unique or superior qualifications to provide the services. Additional services exceeding the specified pre-approved limits, or adding service types to the pre-approved list, requires specific Audit Committee approval. The Audit Committee approved all non-audit services.

“Restricted” non-audit services include nine specific restricted services outlined in the SEC’s final rule on auditor independence issued January 28, 2003. These services are not to be performed by the audit firm.
