                         DEFERRED STOCK OPTION GAIN PLAN


                                    SECTION 1

                            ESTABLISHMENT AND PURPOSE

1.1. ESTABLISHMENT. Effective as of July 25, 1997, Donaldson Company, Inc.
hereby establishes a nonqualified, unfunded, elective deferral plan for a select
group of highly compensated employees known as the "DONALDSON COMPANY, INC.
DEFERRED STOCK OPTION GAIN PLAN."

1.2. PURPOSE. The purposes of this Plan are to allow a select group of
management and highly compensated employees of the Company to defer the receipt
of income that would otherwise be subject to income tax upon exercise of stock
options granted by the Company and to attract and retain certain executive
employees of outstanding competence.




                                    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

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

2.2. 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.

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

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

2.5. CHANGE OF CONTROL -- a "Change in Control" shall be deemed to have occurred

            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


                                      -2-




            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 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 the sale or disposition by the Company of all or
            substantially all of the Company's assets, other than a sale or
            disposition by the Company of all or substantially all of the
            Company's assets to an entity, at 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 in 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
immediately following such transaction or series of transactions. Solely for

                                    SECTION 3

                          ELIGIBILITY AND PARTICIPATION

3.1. ELIGIBILITY. Any officer of the Company who is affirmatively selected by
the Committee shall be an Eligible Employee and may actively participate under
the Plan until the earlier of the officer's Termination of Employment or
transfer to a non-officer position with the Company or its Affiliates. The
Committee may rescind an officer's selection as an Eligible Employee and
discontinue an officer's active participation in the Plan at any time.

3.2. COMMENCEMENT OF PARTICIPATION. An Eligible Employee shall become a
Participant in the Plan when the Eligible Employee is first credited with any
amount pursuant to Section 4.

3.3. TERMINATION OF PARTICIPATION. A person shall cease to be a Participant as

full.

3.4. OVERRIDING EXCLUSION. Notwithstanding anything apparently to the contrary
in this Plan Statement or in any written communication, summary, resolution or

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

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.


                                      -6-




                                    SECTION 4

                           DEFERRED STOCK UNIT AMOUNTS

4.1. DEFERRAL ELECTIONS. An Eligible Employee may file with the Committee a
Deferral Election as to any option to buy Common Stock granted to such Eligible
Employee by the Company, subject to the following:

      (a)   Except as provided in subsection (f) below and subject to the
            modifications described in Sections 5.3 and 5.5, a Deferral Election
            shall be irrevocable once it has been filed with the Committee.

      (b)   Deferral Elections may only be made with respect to options whose
            exercise price may be paid in shares of Common Stock, and shall
            obligate the Eligible Employee making the Deferral Election to pay
            the exercise price and any tax withholding required at the time of
            exercise by attestation to the ownership of shares of Common Stock
            that the Eligible Employee has owned for at least six months and
            that have not been used to exercise another option for at least six
            months.

      (c)   Each Deferral Election shall specify the time and manner in which
            distribution of the portion of the Participant's Account
            attributable to that Deferral Election shall be made; provided,
            however, that distribution may not commence prior to the first
            anniversary of the Exercise Date of the option that is subject to
            the Deferral Election.

      (d)   Nothing in this Plan shall be deemed to extend the period during
            which stock options may be exercised, or to otherwise alter the
            terms of any stock option.

      (e)   Deferral Elections must be made on forms approved by the Committee,
            must be made at such time as the Committee shall determine but not
            less than six months prior to the Exercise Date with respect to
            those options, and shall conform to such other procedural and
            substantive rules as the Committee shall make.

      (f)   Any Deferral Elections with respect to options that have not been
            exercised shall become null and void upon an Eligible Employee's
            Termination of Employment.

4.2. DEFERRED STOCK UNITS. As of each Exercise Date, a Participant's Account
shall be credited with the number of Deferred Stock Units equal to the
difference between (a) and (b):


                                      -7-




      (a)   The number of shares of Common Stock obtained by exercise of the
            option being exercised; and

      (b)   The number of shares of Common Stock required to pay both the
            exercise price of the option being exercised and any required tax
            withholding.

4.3. DISCRETIONARY CREDITS. In the event of any change in the outstanding shares
of common stock of the Company by reason of any stock split or stock dividend in
the form of a split, the Committee shall adjust the number of Deferred Stock
Units in a Participant's Account so that such number equals the number of
Deferred Stock Units in the Account prior to the event, multiplied by a
fraction, the denominator of which is the number of Deferred Stock Units in the
Account prior to the event, and the numerator of which is the number of shares
of Common Stock the Participant would have had after the event if the
Participant had shares of Common Stock immediately prior to the event equal in
number to the number of Deferred Stock Units in the Participant's Account
immediately prior to the event. In the event of any dividend (other than a stock
dividend in the form of a split), recapitalization, merger, consolidation,
spinoff, reorganization, combination or exchange of shares or other similar
corporate change, then if the Committee, or the board of directors of a
successor corporation, shall determine, in its sole discretion, that such change
equitably requires an adjustment in the number of Deferred Stock Units then held
in the Participant's Account, such adjustment shall be made by the Committee or
said board and shall be conclusive and binding for all purposes of the Plan.

4.4. DIVIDEND CREDITS. The number of Deferred Stock Units in a Participant's
Account shall be automatically increased as of each Common Stock dividend
payment date in an amount equal to the number of shares of Common Stock that
could be purchased on such dividend payment date with the cash dividends that
would be paid on a number of shares of Common Stock equal to the number of
Deferred Stock Units in the Participant's Account on the record date for such
dividend.

4.5. VESTING. The Accounts of all Participants shall be 100% Vested at all
times.


                                      -8-




                                    SECTION 5

                           TIME AND MANNER OF PAYMENTS

5.1. TIME OF PAYMENT. Payment of all or, under Section 5.1(b), a portion of a
Participant's Account under the Plan will be made as soon as administratively
feasible following the occurrence of the earliest of the following events:

      (a)   death, or

      (b)   the date of distribution selected by the Participant in writing at a
            time and on a form prescribed by the Committee (Deferral Election).

In no event, however, may payment of the portion of a Participant's Account
attributable to a particular option exercise begin less than one year after the
Exercise Date with respect to that option exercise.

5.2. MANNER OF PAYMENT. The Participant's Account will be paid to a Participant
in either a single lump sum payment or in annual installments of not more than
fifteen (15) years, beginning up to two (2) years after departure from the
Company. 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(b).
Payment shall be made exclusively in the form of shares of Common Stock and cash
for any fractional shares. For purposes of determining any cash payment and any
tax withholding on a payment, the value of Common Stock will be the market price
of such Common Stock as of the close of business on the day prior to the date as
of which the payment is made.

5.3. CHANGES IN TIME AND MANNER OF PAYMENT. Notwithstanding the foregoing, a
Participant may make a new election concerning selection of the time and form of
payment authorized pursuant to this Section 5.3 (the "New Election") in
accordance with the following terms and conditions, unless waived or modified by
the Committee:

      (a)   A New Election shall only be permitted once and must be made and
            become effective as hereinafter provided, if at all, prior to a
            Participant's Termination of Employment;

      (b)   A New Election shall become effective twelve months after it is
            received by the Company;

      (c)   A New Election shall be subject to the limitations described in
            Section 4.1(a) through (f); and

      (d)   If any of the events set forth in Section 5.1 of the Plan occur
            prior to the effective date of a New Election with respect to
            previously credited deferrals,

            then payments shall be paid hereunder to or with respect to the
            Participant according to the elections in effect at the time of the
            event.

5.4. CHANGE IN CONTROL DISTRIBUTIONS. A Participant or Beneficiary will receive
a distribution of his or her entire Account if a Change in Control has occurred.
Distribution of the entire Account shall be made on the date the Change in
Control occurs. Such distribution shall be made in a lump sum stock
distribution.

5.5. ACCELERATION OF PAYMENTS.

      5.5.1. WHEN AVAILABLE. A Participant or Beneficiary who is receiving
installments may receive an accelerated payment of his or her entire Account
(after reduction for the forfeiture described in Section 5.5.2). To receive such
an accelerated payment, the Participant or Beneficiary must file a written
payment application with the Committee. Payment of the accelerated payment
(after reduction for the forfeiture described in Section 5.5.2) shall be made as
soon as administratively feasible following the approval of a completed
application by the Committee. Such accelerated payment shall be made in a lump
sum cash payment. The amount of the accelerated payment shall be equal to the
value of the Account as of such distribution date (after reduction for the
forfeiture described below).

      5.5.2. FORFEITURE. Upon the approval of an accelerated payment, there
shall be irrevocably forfeited from the Account of the Participant or
Beneficiary an amount equal to six percent (6%) of the Account. In addition, if
the Participant is an active employee at the time of the accelerated payment,
the Participant will not be an Eligible Employee under this Plan for two (2)
years following such accelerated payment.

5.6. DEATH BENEFIT. In the event of a Participant's death prior to the date on
which distribution of the Participant's Account is made, 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 4.4) in a lump sum or in installments, as
previously elected by the Participant, to the Participant's designated
Beneficiary as soon as administratively feasible.

5.7. 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.

                                    SECTION 6

                          DEFERRED STOCK UNIT ACCOUNTS

6.1. PARTICIPANT ACCOUNTS. The Committee shall cause a bookkeeping account to be
kept in the name of each Participant which shall reflect the Deferred Stock
Units credited to a Participant.

6.2. 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.

                                    SECTION 7

                                     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.

                                 ADMINISTRATION

8.1. 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. 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.

8.2. 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.

8.3. 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.

8.4. 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.

8.5. CLAIMS PROCEDURE. Until modified by the Committee, the claims procedure set
forth in this Section 8.5 shall be the claims procedure for the resolution of
disputes and disposition of claims arising under the Plan.

      8.5.1. 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,

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


                                      -13-




      (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.

     8.5.2. 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.

      8.5.3. 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.

      (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


                                      -14-




            a copy of this Plan Statement and all other pertinent documents in
            the possession of the Company and its Affiliates.

8.6. 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. The Participant agrees
to cooperate with the Company in connection with any tax audit.

8.7. 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.

8.8. 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 misstatement, is found to be understated as a result of such
misstatement of the participant. However, the benefit of any


                                      -15-




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).


                                      -16-




                                    SECTION 9

                                  MISCELLANEOUS

9.1. 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.

9.2. 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.

9.3. 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.

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

9.5. 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.

9.6. AMENDMENT AND TERMINATION. The Company reserves the power to unilaterally
amend this Plan at any time, either prospectively or retroactively or both:

      (a)   in any respect by resolution of its Board of Directors; and

      (b)   in any respect that does not materially increase the cost of the
            Plan by action of the Committee (with the written concurrence of the
            Chief Executive Officer of the Company).

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.


                                      -17-




9.7. 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 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.
