--------------------------------------------------------------------------------

5.     Selection of Participants and Performance Objectives. Prior to the
commencement of each Incentive Compensation Award Period, or at such later time
as determined by the Committee in its discretion, the Committee shall determine
in writing (i) the Participants who shall be eligible to receive an Incentive
Compensation Award for such Incentive Compensation Award Period, (ii) the
performance objective(s) applicable to such Incentive Compensation Award, which
shall be based on any one or more of the business criteria determined by the
Committee, and (iii) the formula for computing the amount of the Incentive
Compensation Award payable to each Participant if the performance objective(s)
is(are) achieved. The amount of an Incentive Compensation Award may be
denominated in cash and/or in shares of the Company’s common stock, provided
that all amounts paid under the Plan shall be in cash. Any performance objective
based on one or more business criteria may, in the Committee’s discretion, be
expressed in absolute amounts, on a per share basis, relative to one or more
other business criteria, as a growth rate or change from preceding periods, or
as a comparison to the performance of specified companies or a published or
special index (including stock market indices) or other external measures, and
may relate to the performance of one or any combination of the Company as whole,
a business unit, a geographic region, or one or more subsidiaries of the Company
or a Participant’s individual performance .

6.    Establishing Performance Objectives. In establishing and measuring
achievement against a performance objective applicable to any Incentive
Compensation Award Period, the Committee may provide that one or more
adjustments may be made to the business criteria on which the performance
objective is based under such circumstances as the Committee shall determine in
its discretion, which may include adjustments for events such as the following
that occur during an Incentive Compensation Award Period: (i) asset write-downs,
(ii) litigation or claim judgments or settlements, (iii) the effect of changes
in tax laws, accounting principles or other laws or provisions affecting
reported results, (iv) any reorganization and restructuring programs, (v)
acquisitions or divestitures, (vii) foreign exchange gains and losses and (viii)
other events that are unusual in nature or occur infrequently.

7.    Incentive Compensation Award Determination. The Committee shall make a
written determination prior to payment of an Incentive Compensation Award as to
the degree to which the applicable performance objective(s) has(have) been
attained and the resulting Incentive Compensation Award payment amount. With
respect to any such Committee determination, approved minutes of the meeting in
which the determination is made shall be treated as written determination.

8.     Discretion to Reduce or Increase Awards. The Committee, in its sole and
absolute discretion, may reduce or increase the amount of any Incentive
Compensation Award that would otherwise be payable to a Participant based on
such factors as the Committee deems relevant and appropriate.

9.     Active Employment Requirement. Except as provided below, an Incentive
Compensation Award shall be paid for an Incentive Compensation Award Period only
to a Participant who is actively employed by the Company (or on approved
vacation or other approved leave of absence) throughout the Incentive
Compensation Award Period and who is employed by the Company on the date the
Incentive Compensation Award is paid. The Committee may in its sole discretion
(i) grant an Incentive Compensation Award for an Incentive Compensation Award
Period to a Participant who is first employed or who is first promoted to a
position conferring eligibility to participate in this Plan during the Incentive
Compensation Award Period, or (ii) authorize payment of an Incentive
Compensation Award to a Participant whose employment is terminated during the
Incentive Compensation Award Period because of the Participant’s retirement (as
defined in the Company’s 401(k) plan), death, or disability as defined in
Section 22(e)(3) of the Code. In such cases of active employment for part of an
Incentive Compensation Award Period, a pro rata Incentive Compensation Award may
be paid for the Incentive Compensation Award Period.

10.     Payment and Deferrals of Incentive Compensation Award.

(a)    An Incentive Compensation Award shall be paid to the Participant for the
Incentive Compensation Award Period as provided in this Plan. The Company shall
pay the Incentive Compensation Award to the Participant in such form as the
Committee may determine and at such time as the Committee may determine after
the Committee certifies that the Incentive Compensation Award is payable as
provided in Section 8, but no later than March 15 of the year following the year
in which the Incentive Compensation Award Period ends. In the event of the
Participant’s death, any Incentive Compensation Award shall be paid to the
Participant’s spouse or, if there is no surviving spouse, the Participant’s
estate. Payments under this Section shall operate as a complete discharge of the
Committee and the Company. The Company shall deduct from any Incentive
Compensation Award paid under the Plan the amount of any taxes required to be
withheld by the federal or any state or local government.

(b)    The Committee may, in its sole and absolute discretion, permit an
Eligible Senior Executive who is entitled to receive an Incentive Compensation
Award to elect to defer payment of such Incentive Compensation Award in
accordance with the terms of the Polaris Industries Inc. Supplemental
Retirement/Savings Plan.

Compensation Award; (b) give a Participant any rights whatsoever with respect to
shares of common stock of the Company; (c) limit in any way the right of the
Company to terminate an Eligible Senior Executive’s employment with the Company

incentive compensation arrangements for the benefit of individuals who are
Participants hereunder as the Board or Committee, as the case may be, deems
appropriate and in the best interests of the Company.

13.     Nonassignment. The right of a Participant to the payment of any
Incentive Compensation Award under the Plan may not be assigned, transferred,
pledged, or encumbered, nor shall such right or other interests be subject to
attachment, garnishment, execution, or other legal process.

14.     Amendment or Termination of the Plan. The Board may amend or terminate
the Plan at any time, except that no amendment or termination shall be made that
would impair the rights of any Participant to an Incentive Compensation Award
that would be payable were the Participant to terminate employment on the
effective date of such amendment or termination, unless the Participant consents
to such amendment or termination.

15.     Governing Law. The validity, construction, interpretation,
administration and effect of the Plan and of its rules and regulations, and
rights relating to the Plan, shall be determined solely in accordance with the
laws of the State of Minnesota, other than the conflict of law provisions of
such laws.
