                     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 14, 2003. 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 6, 2003.

2.    Q:    Who is entitled to vote at the annual meeting?

      A:    Only common shareholders of record at the close of business on
            February 14, 2003 are entitled to vote at the annual meeting. As of
            the record date, 25,593,524 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 approve Deloitte & Touche LLP as independent
            auditors for 2003, and on any other business that is properly
            brought before the meeting, including shareholder proposals.

 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:

            -    Telephone

            -    Internet

            -    Mailing the 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, FOR the appointment of Deloitte & Touche LLP as
            independent auditors, and AGAINST the shareholder proposal.

            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.

 7.   Q:    Where and when will I be able to find the results of the voting?

      A:    The results will be announced at the Annual Meeting of Shareholders.
            Otter Tail Corporation will publish the final results in its
            quarterly report on Form 10-Q for the quarter ending June 30, 2003
            to be filed with the Securities and Exchange Commission. You may
            also find the results on our website, www.ottertail.com.

 8.   Q:    Who bears the cost of soliciting votes for the annual meeting?

      A:    Otter Tail Corporation will pay the cost of preparing, assembling,
            printing, mailing, and distributing these proxy materials. In
            addition to soliciting proxies by mail, officers and employees of
            Otter Tail Corporation may solicit them by telephone or in person.
            Employees receive no additional compensation for these solicitation
            activities.

                      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, Nominating Committee, and Executive Committee
so that certain important matters can be addressed in more depth than may be
possible in a full Board meeting. Here is a brief description of each committee.

Audit Committee

The Audit Committee reviews financial results of Otter Tail Corporation,
accounting and control procedures, and supervises the audit function. This
committee is composed of five members of the Board of Directors who, for 2002,
were Dennis R. Emmen, Kenneth L. Nelson, Nathan I. Partain, Gary J. Spies, and
Robert N. Spolum. This committee held four meetings in 2002. For further
information on the actions of the Audit Committee, please refer to the Report of
the Audit Committee on page 14.

Compensation Committee

The Compensation Committee reviews the compensation of officers and the fees of
Directors of Otter Tail Corporation and makes recommendations on compensation
and fees to the Board of Directors. This committee administers the 1999 Employee
Stock Purchase Plan and 1999 Stock Incentive Plan. This committee is composed of
four members of the Board of Directors who, for 2002, were Thomas M. Brown,
Dennis R. Emmen, Maynard D. Helgaas, and Arvid R. Liebe. The committee held
three meetings in 2002.

Executive Committee

The Executive Committee exercises certain powers of the Board between normally
scheduled Board meetings and performs such duties as the Board may assign to it.
This committee is composed of four members of the Board of Directors who, for
2002, were Arvid R. Liebe, John C. MacFarlane, Nathan I. Partain, and Robert N.
Spolum. This committee held one meeting in 2002.

Nominating Committee

The Nominating Committee identifies qualified nominees to succeed to Board
membership. Any shareholder may submit recommendations for membership on 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. The Nominating
Committee is composed of four members of the Board of Directors who, for 2002,
were Thomas M. Brown, Maynard D. Helgaas, Nathan I. Partain, and Gary J. Spies.
This committee held five meetings in 2002.

The full Board of Directors held a total of seven regularly scheduled and
special meetings in 2002. The Board of Directors also held a planning retreat
with senior management. Each incumbent Director attended at least 75 percent of
the total of 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.

                             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 $2,000 per year. In addition, Directors receive an actual expense
reimbursment 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 2002, Directors received 1,000 shares of Restricted Stock, granted under the
terms of the 1999 Stock Incentive Plan. The Restricted Stock shares, 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 the payments pursuant
to the Otter Tail Corporation's Deferred Compensation Plan for Directors. The
deferral may be in the form of cash or stock. Cash deferrals receive interest at
a rate equal to 1% over the prime commercial rate of U.S. Bank National
Association. Stock is deferred in the form of Restricted Stock Units and is
credited quarterly with dividend equivalents equal to the dividend rate on the
Otter Tail Corporation's Common Stock.

                             EXECUTIVE C0MPENSATION

Compensation Committee Report on Executive Compensation

The Compensation Committee of the Board of Directors is composed solely of
Directors who are not current employees of Otter Tail Corporation. This
committee is responsible for developing Otter Tail Corporation's executive
compensation program 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.

The Compensation Committee develops annual recommendations for compensation for
the Chief Executive Officer and the other executive officers. The committee
reviews market-based data prepared by Otter Tail Corporation's Senior Manager,
Compensation and Benefits, in consultation with an independent executive
compensation consultant, Towers Perrin.

Towers Perrin prepared 2002 market-based compensation data for Otter Tail
Corporation. The Towers Perrin analysis established the market competitiveness
for the four top management positions of Otter Tail Corporation, providing
information on base salary, annual bonus, and total direct compensation.

Towers Perrin provided market data for both the 50th and 75th percentile. Otter
Tail Corporation utilized the 50th percentile as the midpoint for base salary
for each executive officer position and calculated salary ranges at 20 percent
above and below the midpoint. Midpoints and ranges were based on total
consolidated revenue of Otter Tail Corporation.

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 analysis. The committee may adjust
base salaries, however, as it sees fit without respect to the analysis or any
other objective criteria.

ANNUAL INCENTIVE BONUS

In 2002, the Compensation Committee utilized an incentive bonus plan for Otter
Tail Corporation's four top executive officers. The Otter Tail Corporation
Management Incentive Plan provides incentives to these officers if Otter Tail
Corporation achieves certain performance targets. The Compensation Committee is
responsible for setting these performance targets near the end of the first
quarter each year and establishes total target payout percentages for each of
these officers. The performance targets are:

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 1/2 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 2002.

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 1/2 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 exceeded the targeted performance level for return on equity
      in 2002.


                                                                               8




3.    Utility net income. Each officer, except Mr. Molbert, receives 25 percent
      of the total target payout if the utility achieves its targeted net
      income. Mr. Molbert receives 10 percent of the total target payout if the
      utility achieves its targeted net income; he receives 5 percent of his
      total target payout if the utility achieves the minimum performance level.
      Each officer receives 12 1/2 percent of the total target payout if the
      utility achieves the minimum performance level and additional increments
      up to 200 percent of the target payout. Utility net income reached the
      maximum performance level in 2002.

4.    Varistar return on capital. Each officer, except Mr. Molbert, receives 25
      percent of the total target payout if Varistar achieves its targeted
      return on capital. Each officer receives 12 1/2 percent of the total
      target payout if Varistar achieves the minimum performance level. Mr.
      Molbert receives 40 percent of his total target payout if Varistar
      achieves its targeted return on capital; he receives 20 percent of his
      total target payout if Varistar achieves its minimum performance level for
      return on capital. Each officer receives up to 175 percent of the total
      target payout, if Varistar exceeds its targeted performance level for
      return on capital. Otter Tail Corporation exceeded the targeted
      performance level for Varistar return on capital in 2002.

The Compensation Committee has discretion over treatment of extraordinary gains,
write-offs, or other events in determining the amount of incentive bonus to be
paid to eligible employees. All incentive payments for 2002 were based upon
reported results, except for Corporate earnings per share.

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 Board of Directors has
designated the Compensation Committee to administer the plan.

In 2002 the Compensation Committee awarded restricted stock grants for 66,800
common shares to the named 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 derived from the
Towers Perrin analysis 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. The
restricted shares vest at a rate of 25% per year.

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 2002, the
committee granted the Chief Executive Officer an award of restricted stock of
34,400 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.

A participant's final average earnings 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. As of December 31, 2002,
the annual final average earnings and actual credited years of service for each
of the named officers were as follows: Mr. MacFarlane, $380,956 (40 years); Mr.
Erickson, $229,193 (22 years), Mr. Molbert, $254,000 (1 year), Mr. Kjellerup,
$194,223 (40 years), Mr. Moug, $215,000 (1 year) and Mr. Koeck, $164,533
(3 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 table on page 11 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 named officers 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. MacFarlane, Mr. Erickson,
Mr. Kjellerup and Mr. Koeck, equal to 70% of the executive's salary and bonuses
during the 12 months before retirement offset by the executive's Social Security
benefit and the amount of the executive'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 and Mr. Moug are also participants in the Executive Survivor and
Supplemental Retirement Plan. The benefit for Mr. Molbert and 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 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.


                                                                              12




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 2002,
and bonus determined by actuarial assumptions based on past financial
performance, is as follows: Mr. Erickson, $289,284; Mr. Molbert, $166,196; Mr.
Kjellerup, $115,960; Mr. Moug, $82,902; and Mr. Koeck, $97,460. Mr. MacFarlane
retired on May 1, 2002 and is currently receiving retirement benefits under the
Plan.

Severance and Employment Agreements

Otter Tail Corporation has entered into change of control severance agreements
(the "Severance Agreements") with each of its executive officers, including the
named officers. 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.

Otter Tail Corporation has entered into employment agreements with Mr. Erickson,
Mr. Molbert, Mr. Moug, and Mr. Koeck. The agreements provide that if Otter Tail
Corporation terminates the employment of one of the officers for cause or if one
of the officers terminates the employment relationship without good reason that
the officer shall receive base pay and benefits through the date of termination.
Alternatively, if Otter Tail Corporation terminates the employment of one of the
officers for any other reason, or if one of the officers terminates the
employment relationship for good reason, Otter Tail Corporation shall pay a
severance payment equal to one and one-half times the sum of the officer's base
pay plus his most recent annual incentive payment in full satisfaction of Otter
Tail Corporation's obligations to the officer.

                            REPORT OF AUDIT COMMITTEE

The Audit Committee of Otter Tail Corporation's Board of Directors is composed
of five independent Directors, as defined under Rule 4200 of the National
Association of Securities Dealers, and operates under a written charter
adopted by the Board of Directors. The Audit Committee recommends to the Board
of Directors, subject to shareholder ratification, the selection of Otter Tail
Corporation's independent accountants, currently Deloitte & Touche LLP.

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, 2002, filed with the Securities and
Exchange Commission.

                              APPROVAL OF AUDITORS

At the Annual Meeting, the Board of Directors will propose that shareholders
approve the appointment of the firm of Deloitte & Touche LLP as the certified
public accountants to audit the consolidated financial statements of Otter Tail
Corporation for 2003. This firm has no direct or indirect financial interest in
Otter Tail Corporation. A partner of the certified public accounting firm of
Deloitte & Touche LLP will be present at the annual meeting to answer questions
and to make a statement if he or she desires to do so. Proxies, unless otherwise
directed thereon, will be voted in favor of this proposal.

AUDIT FEES

Audit fees that Deloitte & Touche LLP billed to Otter Tail Corporation for audit
of Otter Tail Corporation's annual consolidated financial statements for 2002
and the consolidated financial statements included in Otter Tail Corporation's
quarterly reports on Form 10-Q for 2002 totaled $410,875.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

Otter Tail Corporation did not engage Deloitte & Touche LLP to provide advice
regarding financial information systems design and implementation during 2002.

ALL OTHER FEES

Fees that Deloitte & Touche LLP billed to Otter Tail Corporation for all other
nonaudit services rendered to Otter Tail Corporation during 2002, totaled
$145,035, primarily for tax-related services. The Audit Committee considered and
confirmed that the provision of these nonaudit services was compatible with
maintaining the independence of Deloitte & Touche LLP as Otter Tail
Corporation's independent auditors.

              SHAREHOLDER PROPOSAL FOR 2003 ANNUAL MEETING

The following shareholder proposal was received by Otter Tail Corporation for
consideration by shareholders. It is presented below in the exact form it was
received.

BACKGROUND INFORMATION: THIS RESOLUTION CONCERNS EXPENSING STOCK OPTIONS. BELOW
IS PERTINENT RELATED INFORMATION.

Whereas: Excessive executive compensation has become a reality in corporate
America. Included are increased executive compensation plans, severance and
employment agreements, special executive pensions and reduced cost stock option
plans. Directors are now participating also.

Regarding Otter Tail, those provisions are referred to in the Proxy Statement.
Their wording makes it virtually impossible for the average person to decipher.

In addition to attractive stock option provisions, the Board of Directors
compensation has risen from $7,800 in 1993 to around $28,000 in 2002.

An example of executive compensation: The 1991 total compensation of CEO John
MacFarlane was $192,800. The 2001 total compensation was $713,000 plus options
at reduced pricing on 125,000 shares. To show the increasing value of stock
options to management, if Mr. MacFarlane purchased and sold his year 2000
granted options on the same day, he would have a guaranteed profit of over
$950,000. This assumes the selling price of $27.50 as this resolution is written
on November 14, 2002.

In 2001 a number of officers exercised options, purchasing and selling the
shares at the same time. One executive officer sold 13,500 shares in August for
an immediate gain of $120,000+.

In 2002 the same trend increased. A number of directors and officers did
simultaneous transactions with instant profits of from $19,000 to well over
$100,000.

These examples show that stock options are increasing as a component of total
compensation. We feel the Company should expense them when granted.

In 1999 Otter Tail initiated the Stock Incentive Plan authorizing 2.6 Million
shares. At year-end 2001 there were 24.7 Million common shares outstanding.
Those original shares in the Plan amount to over 10% of all outstanding shares.

In the 2001 Otter Tail annual report, management explained they would not
expense them when granted. The footnotes indicate that had they been expensed,
earnings per share would have decreased from $1.68 reported to $1.64.

With the numerous scandals in corporate America, conservative reporting of stock
options should be initiated, even though not mandatory.

Recognizing the same concern we are making, most large companies see the wisdom
of that and are reporting and expensing them when granted.

RESOLVED:

1.    That the Board of Directors initiate expensing all options when granted.

2.    All future stock option grants be reporting in the financial statements
      and not in the footnotes.

                   OTTER TAIL CORPORATION'S OPPOSITION TO THE
                              SHAREHOLDER PROPOSAL

The Board of Directors strongly opposes the shareholder proposal and urges you
to vote AGAINST it. Otter Tail Corporation accounts for stock options using the
"intrinsic value" method of accounting. Contrary to the assertion in the
proposal, the intrinsic value method used by Otter Tail Corporation is the
method used by the vast majority of U.S. public companies and is an acceptable
method under generally acceptable accounting principles. The proposal would
require Otter Tail Corporation to shift to the "fair value" method of
accounting, used by relatively few U.S. public companies.

The intrinsic value method of accounting for stock options measures compensation
cost as the excess of the market price of the stock at the grant date over the
exercise price, and generally results in no recorded expense for stock option
awards at the time the awards are granted. When the intrinsic value method is
used, accounting rules require that the impact of the fair value method of
accounting be disclosed in the footnotes to the financial statements. Otter Tail
Corporation has followed these rules in our financial statements.

We believe it is in the best interest of shareholders to follow the most widely
used industry practice when given a choice under the accounting rules. Although
some public companies have announced plans to expense employee stock options on
the grant date, the vast majority of U.S. public companies account for options
using the intrinsic value method and disclose in the notes to the financial
statements the estimated impact on earnings as if employee stock options had
been expensed when granted. These pro forma disclosures, which are included in
the Notes to our 2002 financial statements, provide a reasonable indication to
shareholders of the estimated cost of employee stock options.

The proposal would require Otter Tail Corporation to shift to the "fair value"
method of accounting for stock options. The "fair value" method typically
measures compensation cost at the grant date based on the fair value of the
stock option award and recognizes it as an expense on the income statement,
usually over the vesting period of the option. However, under the fair value
method, there are at least three distinct methods prescribed by current
accounting rules for computing "fair value," and the existing guidance related
to "fair value" calculations is subject to varying interpretations. We believe
these factors detract from the reliability of the fair value method and can lead
to inconsistency and incomparability even among the relatively few public
companies that have adopted this method.

The Financial Accounting Standards Board and other rulemaking bodies are
currently studying the standards for accounting for employee stock options and
may at some time in the future adopt new rules. The Board of Directors does not
believe it to be in the best interests of Otter Tail Corporation to adopt a new
accounting method now that ultimately may be inconsistent with the new rules.
Furthermore, we believe that the choice between two permitted accounting
principles is an ordinary business decision that should be made by the Board of
Directors and management, with the advice of our independent auditors and legal
advisors. Accordingly, the Board of Directors urges you to vote AGAINST this
proposal.

The affirmative vote of a majority of the common shares present and entitled to
vote with respect to the shareholder proposal is required to approve the
proposal. The Board of Directors urges you to vote AGAINST the proposal.
