                               (2005 RESTATEMENT)


                                    SECTION 1

                               HISTORY AND PURPOSE

1.1. HISTORY. Donaldson Company, Inc. sponsors an unfunded, nonqualified
deferred compensation for a select group of highly compensated employees, known
as the "DONALDSON COMPANY, INC. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN". The
Plan, in its most current amended and restated form, is maintained under a
document effective August 1, 2003 (the "Prior Plan Statement"). Effective as of
January 1, 2005, Donaldson Company, Inc. hereby amends and restates the Plan in
the manner hereinafter set forth. Credits made to the Plan which relate entirely
to services performed on or before December 31, 2004 shall continue to be
governed under the terms of the Prior Plan Statement. Credits which relate all
or in part to services performed on or after January 1, 2005 shall be made
subject to the terms of this Plan statement, the terms of which are intended to
comply with the deferred compensation provisions in the American Jobs Creation
Act of 2004.

1.2. PURPOSE. The purpose of this Plan is to enable the Company to provide
supplemental retirement benefits to a select group of management or highly
compensated employees such that the sum of the supplemental benefits, certain
other retirement benefits provided by Company, and benefits provided by prior
employers, will not be less than a predetermined portion of the employee's final
average compensation.







                                    SECTION 2

                                   DEFINITIONS

The following words and phrases shall have the following meanings, unless a
different meaning is plainly required by the context. Any masculine terminology
used in the Plan shall also include the feminine gender and the definition of
any terms in the singular shall also include the plural.

2.1. ACCOUNT -- the compensation account established under this Plan for a
Participant pursuant to Section 6.1.

2.2. ACTUARIAL EQUIVALENT -- a benefit of equivalent value computed on the basis
of actuarial tables, factors and assumptions set forth in Appendix C to the
Donaldson Company, Inc. Salaried Employees' Pension Plan.

2.3. AFFILIATE -- a business entity which is under "common control" with the
Company or which is a member of an "affiliated service group" that includes the
Company, as those terms are defined in section 414(b), (c) and (m) of the Code.
A business entity shall also be treated as an Affiliate if, and to the extent
that, such treatment is required by regulations under section 414(o) of the
Code. In addition to said required treatment, the Committee may, in its
discretion, designate as an Affiliate any business entity which is not such a
"common control" or "affiliated service group" business entity but which is
otherwise affiliated with the Company, subject to such limitations as the
Committee may impose.

2.4. BASIC RETIREMENT PLAN BENEFITS -- the single lump-sum value of the benefits
payable under all of the following plans, determined as of the date of the
Eligible Employee's Termination of Employment, death or Disability, whichever
happens first (or if the value of a plan cannot be determined as of that date,
as of the valuation date for such plan that immediately precedes or follows such
Termination of Employment, death or Disability, whichever happens first, as
determined by the Committee), and subject to the limitations, if any, set forth
below:

     (a)  Donaldson Company, Inc. Retirement Savings and Employee Stock
          Ownership Plan (including profit sharing and PAYSOP), taking into
          account only vested benefits attributable employer contributions;

     (b)  Donaldson Company, Inc. Salaried Employees' Pension Plan;

     (c)  Donaldson Company, Inc. Excess Pension Plan;

     (d)  Donaldson Company, Inc. Deferred Compensation and 401(k) Excess Plan,
          taking into account only benefits attributable to Company Credits;

     (e)  Donaldson Company, Inc. ESOP Restoration Plan;




                                      -2-



     (f)  Any qualified or non-qualified retirement plan, program or arrangement
          provided by the Company or an Affiliate and not listed above, taking
          into account only vested benefits attributable to employer
          contributions; and

     (g)  Any qualified or non-qualified retirement plan, program or arrangement
          provided by a prior employer, taking into account only vested benefits
          attributable to employer contributions.

For purposes of paragraphs (a), (f) and (g) above, "employer contributions" does
not include pre-tax contributions to a tax-qualified retirement plan elected by
an Eligible Employee in lieu of current compensation under a 401(k) arrangement,
or any other amount contributed due to an Eligible Employee's election to defer
compensation. If prior to the earliest of the Eligible Employee's Termination of
Employment, death or Disability the Eligible Employee received a distribution of
any benefits that, but for the distribution, would have been included in the
Eligible Employee's Basic Retirement Plan Benefits, such Basic Retirement Plan
Benefits shall be increased by the amount of such distribution, plus interest
thereon at a rate to be determined by the Committee. In the event any of the
foregoing plans do not provide for payment in a single lump-sum, the benefit
taken into account for purposes of this Section 2.4 shall be the single lump-sum
Actuarial Equivalent of the benefit payable under such plan.

2.5. BENEFICIARY -- any person or entity validly designated by the Participant
in accordance with Section 5 to receive the benefits, if any, payable under the
Plan with respect to the Participant after the Participant's death. Designated
persons or entities shall not be considered Beneficiaries until the death of the
Participant.

2.6. BOARD -- the Board of Directors of the Company.

2.7. CHANGE OF CONTROL -- a "Change of Control" shall be deemed to have occurred
if the event set forth in any one of the following paragraphs shall have
occurred:

     (a)  any Person is or becomes the Beneficial Owner, directly or indirectly,
          of securities of the Company representing 25% or more of the combined
          voting power of the Company's then outstanding securities, excluding
          any Person who becomes such a Beneficial Owner in connection with a
          transaction described in clause (i) of paragraph (c) below; or

     (b)  the following individuals cease for any reason to constitute a
          majority of the number of directors then serving: individuals who, on
          the date hereof, constitute the Board and any new director (other than
          a director whose initial assumption of office is in connection with an
          actual or threatened election contest, including but not limited to a
          consent solicitation, relating to the election of directors of the
          Company) whose appointment or election by the Board or nomination for
          election by the Company's stockholders was approved or recommended by
          a vote of at least two thirds (2/3) of the directors then still in
          office who either were directors on



                                      -3-



          the date hereof or whose appointment, election or nomination for
          election was previously so approved or recommended; or

     (c)  there is consummated a merger or consolidation of the Company or any
          direct or indirect subsidiary of the Company with any other
          corporation, other than (i) a merger or consolidation which would
          result in the voting securities of the Company outstanding immediately
          prior to such merger or consolidation continuing to represent (either
          by remaining outstanding or by being converted into voting securities
          of the surviving entity or any parent thereof), in combination with
          the ownership of any trustee or other fiduciary holding securities
          under an employee benefit plan of the Company or any subsidiary of the
          Company, at least 60% of the combined voting power of the securities
          of the Company or such surviving entity or any parent thereof
          outstanding immediately after such merger or consolidation, or (ii) a
          merger or consolidation effected to implement a recapitalization of
          the Company (or similar transaction) in which no Person is or becomes
          the Beneficial Owner, directly or indirectly, of securities of the
          Company representing 25% or more of the combined voting power of the
          Company's then outstanding securities; or

     (d)  the stockholders of the Company approve a plan of complete liquidation
          or dissolution of the Company or there is consummated an agreement for

          least 60% of the combined voting power of the voting securities of
          which are owned by stockholders of the Company in substantially the
          same proportions as their ownership of the Company immediately prior
          to such sale.

Notwithstanding the foregoing, a "Change of Control" shall not be deemed to have
occurred by virtue of the consummation of any transaction or series of
integrated transactions immediately following which the record holders of the
common stock of the Company immediately prior to such transaction or series of
transactions continue to have substantially the same proportionate ownership in
an entity which owns all or substantially all of the assets of the Company

                          ELIGIBILITY AND PARTICIPATION

3.1. ELIGIBILITY. A senior officer of the Company who is affirmatively selected
by the Committee shall be an Eligible Employee and shall participate in the
Plan. Committee selections shall continue in effect until rescinded by the
Committee. The Committee may rescind its selection and thereby discontinue a
senior officer's active participation in the Plan at any time. If any amendment

reauthorized by the Committee or its delegate. If a senior officer's selection
is rescinded (or deemed rescinded), the benefit, if any, provided by this Plan
shall be calculated pursuant to the terms of the Plan in effect when the
rescission (or deemed rescission) took effect, using only the Participant's
compensation through that time, but calculating any offset for other benefits
using the amount of such other benefits at the time of the person's actual
Termination of Employment. In connection with an Eligible Employee's
commencement of participation in the Plan, the Eligible Employee shall elect the
time and form of payment of such Participant's Account as permitted under
Section 5, along with such other elections as the Committee deems necessary or
desirable under the Plan. For these elections to be valid, the election form
must be completed and timely delivered to the Committee and accepted by the
Committee within thirty (30) days after the Participant first becomes eligible
to participate in the Plan.

3.2. COMMENCEMENT OF PARTICIPATION. An Eligible Employee shall become a
Participant in the Plan when the Eligible Employee is first affirmatively
selected as required by Section 3.1.

3.3. TERMINATION OF PARTICIPATION. A person shall cease to be a Participant as
soon as all amounts payable to the Participant have been paid in full.

3.4. OVERRIDING EXCLUSION. Notwithstanding anything apparently to the contrary
in this Plan or in any written communication, summary, resolution or document or
oral communication, no individual shall be a Participant in this Plan, develop
benefits under this Plan or be entitled to receive benefits under this Plan
(either for the employee or his or her survivors) unless such individual is a
member of a select group of management or highly compensated employees (as that
expression is used in ERISA). If a court of competent jurisdiction, any
representative of the U.S. Department of Labor or any other governmental,
regulatory or similar body makes any direct or indirect, formal or informal,
determination that an individual is not a member of a select group of management
or highly compensated employees (as that expression is used in ERISA), such
individual shall not be (and shall not have ever been) a Participant in this
Plan at any time. If any person not so defined has been erroneously treated as a
Participant in this Plan, upon discovery of such error such person's erroneous
participation shall immediately terminate AB INITIO and upon demand such person
shall be obligated to reimburse the Company for all amounts erroneously paid to
him or her.

                                    SECTION 4

                                CREDITED AMOUNTS

4.1. NORMAL RETIREMENT BENEFIT. A Participant whose Termination of Employment
occurs on or after the date the Participant attains age 62 and completes at
least ten (10) years of Pension Service shall be credited with a Normal
Retirement Benefit equal to (a) minus (b):

     (a)  the product of (i), (ii) and (iii):

          (i)  30%;

          (ii) Years of Pension Service, limited to twenty (20); and

          (iii) Final Average Compensation

     (b)  the lump-sum value of the Participant's Basic Retirement Plan
          Benefits.

4.2. EARLY RETIREMENT BENEFIT. A Participant whose Termination of Employment
occurs after the Participant has completed at least fifteen (15) years of
Pension Service and attained age 55, but before the date the Participant attains
age 62 shall, in lieu of any other benefit under this Plan, be credited with an
Early Retirement Benefit equal to the amount determined in the same manner as
provided in Section 4.1 above, except that the product in Section 4.1(a) will
include a fourth factor:

          (iv) Early Retirement Factor

(Example: If a Participant retires early at age 60, the product in Section
4.1(a) would be further multiplied by .96.)

4.3. DISABILITY OR DEATH BENEFIT. A Participant who becomes Disabled prior to
his or her Termination of Employment and after completing at least fifteen (15)
years of Pension Service and before the date he or she attains age 62, or who
dies prior to both the Participant's Termination of Employment and Disability,
shall, in lieu of any other benefit under this Plan, be credited with a
Disability or Death Benefit equal to the amount determined in the same manner as
provided in Section 4.2, taking into account only Pension Service through the
date of Disability or death, and determining the Early Retirement Factor based
on the amount, if any, by which the Participant's Disability or death precedes
the Participant's attainment of age 62.

4.4. VESTING. The applicable amount determined in accordance with this Section 4
shall be credited to the Participant's Account at the time of the Participant's
Termination of Employment, death or Disability, as applicable. Subject to the
forfeiture provisions of Section 8, any Account established for a Participant
under this Plan shall be 100% Vested at all times.

                                    SECTION 5

                           TIME AND MANNER OF PAYMENTS

5.1. TIME OF PAYMENT. Payment of a Participant's Account under the Plan will
commence as soon as administratively feasible after (but not later than December
31 of the Plan Year in which occurs, or if later, sixty (60) days following) the
earliest of the following events:

     (a)  the Participant's death;

     (b)  the Participant's Disability;

     (c)  the date that is twenty four (24) months following the Participant's
          Termination of Employment; or

     (d)  a date of distribution selected by the Participant (at the time the
          Participant first becomes eligible to participate, on a form
          prescribed by the Committee), which may be:

          (i)  a fixed, specified date (E.G., January 1, 2010); or

          (ii) a date that is a specified number of months after the
               Participant's Termination of Employment (not to exceed twenty
               four (24) months); provided, however, that where payment under
               this paragraph (d)(ii) is made to any "key employee" (as defined
               under section 409A of the Code) on account of Termination of
               Employment, such payment shall commence no earlier than six (6)
               months following a Termination of Employment (or upon the death
               of the employee, if earlier) if required to comply with section
               409A of the Code.

5.2. MANNER OF PAYMENT. A Participant's Account shall be paid in cash to the
Participant in either a single lump-sum payment or in annual installments over a
period of not more than twenty (20) years. The Participant must elect a manner
of payment at the time the Participant elects his or her date of distribution
pursuant to Section 5.1(d). Notwithstanding the foregoing, the following special
rules shall apply:

     (a)  in the case of the Participant's death or Disability, payment shall be
          in a single lump sum;

     (b)  if the Participant's Account upon commencement of distribution under
          Section 5.1 is less then Ten Thousand Dollars ($10,000), payment shall
          be in a single lump sum; and


                                      -10-


     (c)  in the event no election was made by the Participant, payment shall be
          in a single lump sum.

5.3. CHANGES IN TIME AND MANNER OF PAYMENT. Notwithstanding the foregoing, a
Participant who is actively employed by the Company may make a new election
concerning selection of the time and form of payment authorized pursuant to this
Section 5.3, subject to the following limitations:

     (a)  Such election must be submitted to and accepted by the Committee at
          least twelve (12) months prior to the date a distribution to the
          Participant would otherwise have been made or commenced;

     (b)  The election shall have no effect until at least twelve (12) months
          after the date on which the election is made;

     (c)  The election may change the time when payment shall commence but only
          if the new date selected by the Participant for commencement shall be
          a date that is at least five (5) years from the prior date of
          distribution selected by the Participant;

     (d)  The election may reduce or extend the number of installment payments
          (subject to the limitations in Section 5.2) so long as the initial
          installment is delayed at least five (5) years from the date
          distribution would have otherwise commenced; and

     (e)  If the participant changes the time and/or form of payment under this
          Section 5.3, payment shall commence as soon as administratively
          feasible after (but not later than December 31 of the Plan Year in
          which occurs, or if later, sixty (60) days following) the earliest of
          the following events:

          (i)  the Participant's death;

          (ii) the Participant's Disability; or

          (iii) the new date selected by the Participant for commencement.

5.4. CHANGE OF CONTROL DISTRIBUTIONS. Notwithstanding any other provision of
this Plan, in the event of a Change of Control, each Participant who incurs a
Termination of Employment with the Company for any reason during the two (2)
year period following such Change of Control shall receive within ten (10)
business days after the date of termination a lump sum payment of the entire
balance contained in the Participant's Account; provided, however, that with
respect to any Participant who separated from service before the date of a
Change of Control, the balance of the Participant's Account shall be paid at the
time and in the manner as elected by the Participant under this Section 5 hereof
(and shall not be commuted to a lump sum or otherwise accelerated by the Change
of Control). Where payment under this Section 5.4 is



                                      -11-



made to any "key employee" (as defined under section 409A of the Code) on
account of Termination of Employment, such payment shall commence no earlier
than six (6) months following a Termination of Employment (or upon the death of
the employee, if earlier) if required to comply with section 409A of the Code.

5.5. DEATH BENEFIT. In the event of a Participant's death, the Company shall pay
the amount of the Participant's Account as of the date of death (as adjusted
from time to time pursuant to Section 6.2) in a lump-sum to the Participant's
designated Beneficiary as soon as administratively feasible after the
Participant's death (but not later than December 31 of the Plan Year in which
the Participant's death occurs, or if later, sixty (60) days following such
death). Payment to a Participant's designated Beneficiary shall be in cash.

5.6. BENEFICIARY DESIGNATION. A Participant shall submit to the Company upon
initial designation as an Eligible Employee in the Plan, and at such other times
as the Participant desires, on a form provided by the Committee, a written
designation of the beneficiary or beneficiaries to whom payment of the
Participant's Account under the Plan shall be made in the event of the
Participant's death. Beneficiary designations shall become effective only when
received by the Company. Beneficiary designations first received by the Company
after the Participant's death, and any designations in effect at the time a
valid subsequent designation is received by the Company, shall be invalid and
have no effect. If a Participant has not designated a Beneficiary, or if no
designated Beneficiary is living on the date of distribution, the Participant's
Account shall be distributed to those persons entitled to receive distribution
of the Participant's benefit under the Donaldson Company, Inc. Salaried
Employees' Pension Plan (1997 Restatement), as amended from time to time.

                                    SECTION 6

                                     ACCOUNT

6.1. PARTICIPANT ACCOUNTS. The Committee shall cause a bookkeeping account to be
kept in the name of each Participant which shall reflect the value of the Normal
Retirement Benefit, Early Retirement Benefit, Disability or death benefit
credited to the Participant at the time of the Participant's Termination of
Employment, death or Disability, whichever applies.

6.2. INVESTMENT OF ACCOUNTS. When the manner of payment is annual installments,
the Participant's Account will be adjusted as of the last day of each Plan Year
to the same extent that an equal amount would be adjusted if it had been
credited to the subfund under the Deferred Compensation Plan that provides a
fixed rate of return.

6.3. CHARGES AGAINST ACCOUNTS. There shall be charged against each Participant's
bookkeeping account any payments made to the Participant or the Participant's
Beneficiary in accordance with Section 5.

                                     FUNDING

7.1. FUNDING. The Company and its Affiliates shall be responsible for paying all
benefits due hereunder. For the purpose of facilitating the payment of benefits
due hereunder, the Company may (but shall not be required to) establish and
maintain a grantor trust pursuant to an Agreement between the Company and a
trustee selected by the Company; provided, however, that any such grantor trust
must be structured so that it does not result in any federal income tax
consequences to any Participant until distributions under Section 5 are actually
received. The Company may contribute to a grantor trust thereby created such
amounts as it may from time to time determine.

7.2. CORPORATE OBLIGATION. Neither the officers nor any member of the Board of
Directors of the Company or any of its Affiliates in any way secures or
guarantees the payment of any benefit or amount which may become due and payable
hereunder to or with respect to any Participant. Each Participant and other
person entitled at anytime to payments hereunder shall look solely to the assets
of the Company and its Affiliates for such payments as an unsecured, general
creditor. Nothing herein shall be construed to give a Participant, Beneficiary
or any other person or persons any right, title, interest or claim in or to any
specific asset, fund, reserve, account or property of any kind whatsoever owned
by the Company or in which it may have any right, title or interest now or in
the future. After benefits shall have been paid to or with respect to a
Participant and such payment purports to cover in full the benefit hereunder,
such former Participant or other person or persons, as the case may be, shall
have no further right or interest in the other assets of the Company and its
Affiliates in connection with this Plan.

                             FORFEITURE OF BENEFITS

All unpaid benefits under this Plan shall be permanently forfeited if the
Committee determines that the Participant, either before or after the
Participant's Termination of Employment or Disability, or before the
Participant's death:

     (a)  engaged in criminal or fraudulent conduct resulting in a hardship to
          the Company or an Affiliate; or

     (b)  breached the Participant's written employment agreement with the
          Company or an Affiliate.

                                    SECTION 9

                                 ADMINISTRATION

9.1. AUTHORITY. The Plan shall be administered by the Committee, which shall
have full discretionary power and authority to administer and interpret the Plan
and to determine all factual and legal questions under the Plan, including but
not limited to the entitlement of Participants and Beneficiaries, and the amount
of their respective interests. Except where necessary to comply with applicable
corporate or securities law, or applicable rules of the New York Stock Exchange
(e.g., with respect to executive officers), the Committee may delegate or
redelegate to one or more persons, jointly or severally, and whether or not such
persons are members of the committee or employees of the Company, such functions
assigned to the Committee hereunder as it may from time to time deem advisable.
Until withdrawn or redelegated by the Committee, all of the Committee's
delegable power and authority under this Section 9.1 shall be deemed delegated
to the Company's Vice President in charge of executive compensation, excluding
only the power and authority to act in such a way as would materially increase
the cost of the Plan.

9.2. LIABILITY. No member of the Committee and no director or member of the
management of the Company or its Affiliates shall be liable to any persons for
any actions taken under the Plan, or for any failure to effect any of the
objective or purposes of the Plan, by reason of insolvency or otherwise.

9.3. PROCEDURES. The Committee may from time to time adopt such rules and
procedures as it deems appropriate to assist in the administration of the Plan.

9.4. CLAIM FOR BENEFITS. No employee or other person shall have any claim or
right to payment of any amount hereunder until payment has been authorized and
directed by the Committee.

9.5. CLAIMS PROCEDURE. Until modified by the Committee, the claims procedure set
forth in this Section 9.5 shall be the claims procedure for the resolution of
disputes and disposition of claims arising under the Plan.

     9.5.1. ORIGINAL CLAIM. Any employee, former employee, or Beneficiary of
such employee or former employee may, if the employee, former employee or
Beneficiary so desires, file with the Committee a written claim for benefits
under the Plan. Within ninety (90) days after the filing of such a claim, the
Committee shall notify the claimant in writing whether the claim is upheld or
denied in whole or in part or shall furnish the claimant a written notice
describing specific special circumstances requiring a specified amount of
additional time (but not more than one hundred eighty (180) days from the date
the claim was filed) to reach a decision on the claim. If the claim is denied in
whole or in part, the Committee shall state in writing:

     (a)  the specific reasons for the denial;


                                      -16-



     (b)  the specific references to the pertinent provisions of this Plan on
          which the denial is based;

     (c)  a description of any additional material or information necessary for
          the claimant to perfect the claim and an explanation of why such
          material or information is necessary; and

     (d)  an explanation of the claims review procedure set forth in this
          Section.

     9.5.2. CLAIMS REVIEW PROCEDURE. Within sixty (60) days after receipt of
notice that the claim has been denied in whole or in part, the claimant may file
with the Committee a written request for a review and may, in conjunction
therewith, submit written issues and comments. Within sixty (60) days after the
filing of such a request for review, the Committee shall notify the claimant in
writing whether, upon review, the claim was upheld or denied in whole or in part
or shall furnish the claimant a written notice describing specific special
circumstances requiring a specified amount of additional time (but not more than
one hundred twenty days (120) from the date the request for review was filed) to
reach a decision on the request for review.

     9.5.3. GENERAL RULES.

     (a)  No inquiry or question shall be deemed to be a claim or a request for
          a review of a denied claim unless made in accordance with the claims
          procedure. The Committee may require that any claim for benefits and
          any request for a review of a denied claim be filed on forms to be
          furnished by the Committee upon request.

     (b)  All decisions on original claims shall be made by the Committee and
          requests for a review of denied claims shall be made by the Committee.

     (c)  The Committee may, in its discretion, hold one or more hearings on a
          claim or a request for a review of a denied claim.

     (d)  Claimants may be represented by a lawyer or other representative at
          their own expense, but the Committee reserves the right to require the
          claimant to furnish written authorization. A claimant's representative
          shall be entitled to copies of all notices given to the claimant.

     (e)  The decision of the Committee on an original claim or on a request for
          a review of a denied claim shall be served on the claimant in writing.
          If a decision or notice is not received by a claimant within the time
          specified, the claim or request for a review of a denied claim shall
          be deemed to have been denied.


                                      -17-



     (f)  Prior to filing a claim or a request for a review of a denied claim,
          the claimant or the claimant's representative shall have a reasonable
          opportunity to review a copy of this Plan Statement and all other
          pertinent documents in the possession of the Company and its
          Affiliates.

9.6. PAYMENTS UPON IMPOSITION OF FEDERAL OR STATE TAXES. If any Participant is
determined to be subject to federal or state income tax on any amount accrued on
his or her behalf under this Plan prior to the time of payment hereunder,
federal or state taxes attributable to the amount determined to be so taxable
shall be distributed by the Plan to such Participant. An amount accrued on his
or her behalf under this Plan shall be determined to be subject to federal
income tax upon the earliest of:

          (i)  a final determination by the United States Internal Revenue
               Service addressed to the Participant which is not appealed to the
               courts;

          (ii) a final determination by the United States Tax Court or any other
               Federal Court affirming any such determination by the Internal
               Revenue Service; or

          (iii) an opinion by the Tax Counsel of the Company, addressed to the
               Company that, by reason of Treasury Regulations, amendments to
               the Internal Revenue Code, published Internal Revenue Service
               rulings, court decisions or other substantial precedent, amounts
               accrued on a Participant's behalf hereunder are subject to
               federal or state income tax prior to payment.

The Company shall undertake at its sole expense to defend any tax claims
described herein which are asserted by the Internal Revenue Service or by any
state revenue authority against any Participant, including attorney fees and
costs of appeal, and shall have the sole authority to determine whether or not
to appeal any determination made by the Internal Revenue Service, by any state
revenue authority or by a lower court. The Company also agrees to reimburse any
Participant for any interest or penalties in respect of federal or state tax
claims hereunder upon receipt of documentation of same.

9.7. LEGAL FEES. If the Company does not pay the benefits required under the
terms of the Plan for reasons other than the insolvency of the Company, the
Company agrees to reimburse any Participant for all legal fees incurred in
enforcing his or her claim to benefits under the Plan.

9.8. ERRORS IN COMPUTATIONS. The Committee shall not be liable or responsible
for any error in the computation of any benefit payable to or with respect to
any Participant resulting from any misstatement of fact made by the Participant
or by or on behalf of any Beneficiary to whom such benefit shall be payable,
directly or indirectly, to the Committee, and used by the Committee in
determining the benefit. The Committee shall not be obligated or required to
increase the benefit payable to or with respect to such Participant which, on
discovery of the




                                      -18-



misstatement, is found to be understated as a result of such misstatement of the
Participant. However, the benefit of any Participant which is overstated by
reason of any such misstatement or any other reason shall be reduced to the
amount appropriate in view of the truth (and to recover any prior overpayment).








                                      -19-



                                   SECTION 10

                                  MISCELLANEOUS

10.1. NOT AN EMPLOYMENT CONTRACT. This Plan is not and shall not be deemed to
constitute a contract of employment between the Company and any employee or
other person, nor shall anything herein contained be deemed to give any employee
or other person any right to be retained in the Company's employ or in any way
limit or restrict the Company's right or power to discharge any employee or
other person at any time and to treat him without regard to the effect which
such treatment might have upon the employee as a Participant in the Plan.

10.2. NONTRANSFERABILITY. A Participant's rights and interest under the Plan,
including amounts payable, may not be assigned, alienated, pledged or
transferred except, in the event of a Participant's death to his Beneficiary. No
benefit payable under this Plan shall be subject to attachment, garnishment,
execution following judgment or other legal process before actual payment to the
Participant or Beneficiary.

10.3. TAX WITHHOLDING. The Company shall withhold the amount of any federal,
state or local income tax or other tax required to be withheld by the Company
under applicable law with respect to any amount payable under the Plan. The
Participant shall not be liable for any tax withholding.

10.4. EXPENSES. All expenses of administering the Plan shall be borne by the
Company.

10.5. GOVERNING LAW. Except to the extent that federal law is controlling, the
Plan shall be construed and enforced in accordance with and governed by the laws
of the State of Minnesota.

10.6. AMENDMENT AND TERMINATION. The Company reserves the power to unilaterally
amend this Plan at any time, either prospectively or retroactively or both by
action of the Committee. The Committee may likewise terminate or curtail the
benefits of this Plan both with regard to persons expecting to receive benefits
in the future and persons already receiving benefits at the time of such action;
provided, however, that the Committee may not amend or terminate the Plan with
respect to benefits that have accrued and are vested pursuant to Section 4 in
any manner that reduces the amount of such benefits or alters the effect of any
Participant election previously filed with the Company. No modification of the
terms of this Plan shall be effective unless it is in writing and signed on
behalf of the Company by a person authorized to execute such writing. No oral
representation concerning the interpretation or effect of this Plan shall be
effective to amend the Plan.

10.7. RULES OF INTERPRETATION. The titles given to the various sections of this
Plan are inserted for convenience of reference only and are not part of this
Plan, and they shall not be considered in determining the purpose, meaning or
intent of any provision hereof. This Plan shall be construed and this Plan shall
be administered to create an unfunded plan providing deferred compensation to a
select group of management or highly compensated employees so



                                      -20-



that it is exempt from the requirements of Parts 2, 3 and 4 of Title I of ERISA
and qualifies for a form of simplified, alternative compliance with the
reporting and disclosure requirements of Part 1 of Title I of ERISA.










                                      -21-
