         The following statement is furnished in connection with the
solicitation of proxies by the Board of Directors of Pentair, Inc. (the
"Company") to be voted at the Annual Meeting of Shareholders of the Company to
be held on Wednesday, May 1, 2002, or at any adjournment or adjournments of such
meeting. Distribution of this proxy statement and proxy to shareholders began on
or about March 25, 2002.

                                  SOLICITATION

         The cost of soliciting proxies and the notices of the meeting,
including the preparation, assembly and mailing of proxies and this statement,
will be borne by the Company. In addition to this mailing, proxies may be
solicited personally or by telephone by regular employees of the Company.
Assistance in the solicitation of proxies is also being rendered by Morrow &
Co., 445 Park Avenue, New York, New York, at a cost to the Company of $7,000
plus expenses of up to $2,500. Furthermore, arrangements may be made with
brokers, banks and similar organizations to send proxies and proxy materials to
beneficial owners for voting instructions, for which the Company will reimburse
such organizations for their expense in so doing and will pay all costs of
soliciting the proxies.

                         REVOCATION AND VOTING OF PROXY

         Any shareholder giving a proxy may revoke it prior to its use at the
meeting by (1) delivering a written notice expressly revoking the proxy to the
Secretary at the Company's offices, (2) signing and forwarding to the Company at
its offices a later dated proxy, or (3) attending the Annual Meeting and casting
his or her votes personally.

         A majority of the outstanding shares will constitute a quorum at the
Annual Meeting. Abstentions and broker non-votes are counted for purposes of
determining the presence or absence of a quorum for the transaction of business.
Pursuant to Minnesota law and the Company's Articles of Incorporation,
abstentions are counted in determining the total number of the votes cast on
proposals presented to shareholders, but will not be treated as votes in favor
of the proposals. Broker non-votes are not counted for purposes of determining
the total number of votes cast on proposals presented to shareholders.

         Unless otherwise directed in the accompanying proxy, the persons named
therein will vote FOR the directors and the other proposals set forth in this
Notice of Annual Meeting of Shareholders. As to any other business that may
properly come before the meeting, they will vote in accordance with their best
judgment. The Company does not presently know of any other business.

(a)      Unless otherwise noted, all shares are held either directly or
         indirectly by individuals possessing sole voting and investment power
         with respect to such shares. Beneficial ownership of an immaterial
         number of shares held by spouses and children has been disclaimed in
         some instances. Amounts listed do not include 841,570 shares held by
         the Pentair, Inc. Master Trust for various pension plans of the Company
         and its subsidiaries. The Trust Investment Committee of such Master
         Trust includes Randall J. Hogan, David D. Harrison and one other
         officer. Although these individuals could be deemed under applicable
         Securities and Exchange Commission rules to "beneficially own" all of
         the shares held by these Plans because of their shared voting and
         investment power with respect to those shares, they disclaim beneficial
         ownership of such shares.
(b)      Represents share units paid under the Fourth Amended and Restated
         Compensation Plan for Non-Employee Directors as to which the beneficial
         owner has no voting or investment power.
(c)      Represents stock options exercisable within 60 days from March 4, 2002.
(d)      Restricted shares issued pursuant to incentive plans as to which the
         beneficial owner has sole voting power but no investment power.
(e)      Represents common shares owned as a participant in the Pentair Employee
         Stock Ownership Plan ("Pentair ESOP") and, for one officer, common
         shares owned as a participant in the Federal-Hoffman Employee Stock
         Ownership Plan ("F-H ESOP"). As of March 4, 2002, Fidelity Management
         Trust Company ("Fidelity"), the Trustee of the Pentair ESOP, held
         2,518,445 common shares (5.0%) and Wells Fargo ("Wells Fargo"), the
         Trustee of the F-H ESOP, held 491,870 common shares (1.0%). Fidelity
         and Wells Fargo disclaim beneficial ownership of all shares. The
         Pentair ESOP and F-H ESOP participants have the right to direct the
         Trustee to vote their shares although participants have no investment
         power

                                       2



         over such shares. The Trustees, except as otherwise required by
         law, vote the shares for which they have received no direction from
         participants, in the same proportion on each issue as they vote those
         shares for which they have received voting directions from
         participants.
(f)      Less than 1% unless otherwise indicated.
(g)      In a Schedule 13G filed February 14, 2002, as of December 31, 2001,
         Fidelity Management & Research Company ("Fidelity"), a wholly owned
         subsidiary of FMR Corp. and a registered investment adviser, reported
         beneficial ownership of 2,896,196 shares as a result of activities as
         an investment adviser. The funds, FMR Corp., through its control of
         Fidelity, and its Chairman, Edward C. Johnson III, reported sole
         dispositive power of such shares, but had no voting power over such
         shares, which is directed by the funds' Boards of Trustees. Fidelity
         carries out the voting of the shares under written guidelines
         established by the funds' Boards of Trustees. Fidelity Management Trust
         Company, a wholly owned subsidiary of FMR Corp. and a bank, reported
         beneficial ownership of 193,700 shares as a result of serving as
         investment manager of institutional account(s). FMR Corp. and its
         Chairman, Edward C. Johnson III, reported sole dispositive power of all
         such shares and sole voting power of 186,000 of such shares. They
         reported no voting control of 7,700 shares owned by the institutional
         accounts. The members of the Edward C. Johnson III family, the
         predominant owners of FMR Corp., have entered into a voting agreement
         and consequently may be a controlling group of FMR Corp under the
         Investment Company Act of 1940, as amended.
(h)      In a Schedule 13G filed February 15, 2002, Putnam Investments, LLC
         ("PI"), a wholly-owned subsidiary of Marsh & McLennan Companies, Inc.,
         reported that two registered investment advisers wholly-owned by PI,
         Putnam Investment Management, LLC., which is the investment adviser to
         the Putnam family of mutual funds ("PIM"), and The Putnam Advisory
         Company, LLC. ("PAC"), which is the investment adviser to Putnam's
         institutional clients, have dispositive power of the shares as
         investment managers but each of the mutual fund's trustees have voting
         power over the shares held by each fund and PAC has shared voting power
         over the shares held by the institutional clients. PI reported shared
         voting power of 570,255 shares and shared dispositive power of
         2,582,432 shares; PIM reported shared dispositive power of 1,598,295
         shares; and PAC reported shared voting power of 570,255 shares and
         shared dispositive power of 984,137 shares.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's directors and executive officers to file with the Securities and
Exchange Commission ("SEC") initial reports of ownership and reports of changes
in ownership of Common Stock and other equity securities of the Company.
Officers, directors, and greater than ten-percent shareholders are required by
SEC regulations to furnish the Company with copies of all Section 16(a) forms
they file.

         Based solely on its review of the copies of such forms furnished to the
Company and written representations from the Company's officers and directors,
the Company believes that it has previously reported any delinquencies for the
fiscal year ended December 31, 2001 and all other persons subject to these
reporting requirements filed the required reports on a timely basis.

                PROPOSALS TO BE ACTED UPON AT THE ANNUAL MEETING

                                     ITEM 1

                              ELECTION OF DIRECTORS

         The Company's By-Laws provide for a Board of Directors (sometimes
referred to herein as the "Board") of not fewer than three members and not more
than fifteen members. The Board is divided into three classes with directors
serving three-year terms but with the beginning date for each term staggered so
that the term of only one class expires in any particular year. Vacancies may be
filled by the Board of Directors or by election at a special meeting of
shareholders. Any director elected to fill a vacancy by the remaining directors
is required to stand for election at the next meeting of shareholders. If the
proposal to amend the Company's Articles of Incorporation and By-Laws are
approved, then the number of directors will be fixed at 10.

         At the forthcoming Annual Meeting, four persons have been nominated as
candidates to be elected to the Company's Board of Directors. Barbara B. Grogan,
Stuart Maitland and Augusto Meozzi, each incumbent directors, have been
nominated for three-year terms, expiring at the 2005 Annual Meeting and William


                                       3



H. Hernandez, who was appointed to the Board in July 2001, subject to election
at the upcoming Annual Meeting, has been nominated for a two-year term, expiring
at the 2004 Annual Meeting. Five other directors have terms of office that do
not expire at this time and who will be continuing to serve his or her full
term. Although there will be one vacancy remaining on the Board following this
election, proxies cannot be voted for a greater number of directors than the
number nominated. Unless you direct otherwise, proxies will be voted FOR the
election of all nominees listed below. Should any nominee decline or be unable
to accept such nomination or to serve as director (an event management does not
now expect to occur), proxies will be voted FOR a substitute nominee or nominees
in accordance with the best judgment of the person or persons acting under them.

         Information concerning the persons nominated for election as directors,
as well as those continuing in office, is set forth on the following pages.

(held on the same day) because of a death in the family.

COMMITTEES OF THE BOARD

         The Audit and Finance Committee is responsible, among other things, for

DIRECTORS' COMPENSATION

         It is the Company's philosophy that a significant portion of directors'
compensation should be tied to long-term growth in shareholder value. In 2001,
non-employee directors were paid an annual retainer of $24,000 ($29,000 for the
Chair of the Compensation and Human Resource Committee), $68,341 of deferred
compensation in the form of share units under the Fourth Amended and Restated
Compensation Plan for Non-


                                       5



Employee Directors (the "Non-Employee Director Plan"), $1,500 for attendance at
each Board meeting, $1,000 ($2,000 for committee chairs) for attendance at each
committee meeting, and $500 for participation in a telephone conference in lieu
of a meeting. In recognition of his 25 years of service on the Board of
Directors, the Board made an award in 2001 of deferred compensation of $68,341
in the form of share units under the Non-Employee Director Plan to Quentin
Hietpas, who retired from the Board effective April 25, 2001. Under the
Non-Employee Director Plan, non-employee directors of the Company may elect to
defer payment of all or a portion of their annual retainer and meeting fees in
the form of share units. The Plan provides for a Company match of 25% on the
first $750 per month deferred in the form of share units. The value of a share
unit is equal to the market value of a share of Common Stock. Share units carry
no voting or investment power. Participants and amounts deferred under the Plan
are shown below:

         The Outside Directors Nonqualified Stock Option Plan provides for the
granting of options to purchase Common Stock to directors who are not employees
of the Company. The Plan provides for automatic annual grants to the directors
and offers alternative forms of payment of the exercise price including
surrender of Common Stock. The persons to receive options, the number of options
granted, and the terms of the options are determined by the Plan. No option
granted under the Plan may extend for a period of more than 10 years from the
date of the grant and no option exercise price may be less than the current
market price of Common Stock on the date of award of such option. Beginning with
stock options granted in 1998, if the option holder exercises the stock option
during the first five years of the option term by tendering to the Company
common shares owned by that person, the Company can grant to such person, an
option ("Reload Option") to purchase common shares equal to the number of shares
tendered. The Reload Option may be exercised during the remaining term of the
original stock option period. The Reload Option exercise price is equal to the
market price per share on the date the shares are tendered.

BUXTON RETIREMENT AND CONSULTING ARRANGEMENTS

         Winslow H. Buxton, Chairman of the Board of Directors, retired as Chief
Executive Officer of the Company, effective January 1, 2001 and as an employee
of the Company effective April 30, 2001. He will retire from the Board effective
as of the 2002 Annual Meeting of the Shareholders. In connection with his
retirement the Company has entered into certain arrangements with Mr. Buxton.

         In connection with his retirement and in exchange for a non-competition
and non-solicitation agreement and a standard release of any claims against the
Company, Mr. Buxton is receiving a supplemental benefit payment of $60,900 per
month, payable in the form of a life annuity, which includes his accrued benefit
under the Company's Supplemental Executive Retirement Plan. His awards under the
Omnibus Plan, including restricted stock (26,397 shares), stock options and
Incentive Compensation Units ("ICUs") were fully vested as of April 30, 2001 and
the value of the ICUs ($731,216) was paid to him as of such date. Mr. Buxton and
his spouse are also being provided medical and dental coverage, including
reimbursement of expenses, as well as life insurance. He may also have accrued
benefits through April 30, 2001, under other plans, such as the RSIP, Deferred
Compensation Plans or the Pentair Pension Plan, which are being paid out in
accordance with the terms of such plans.

         Through April 30, 2001, Mr. Buxton was compensated at an annual rate of
$825,700 (the rate of compensation in effect on January 1, 2001, the effective
date of his retirement as CEO). Beginning May 1, 2001 and ending on April 30,
2002, the Company is compensating Mr. Buxton under a consulting arrangement for
services rendered as Chairman of the Board at sixty percent (60%) of his former
annual salary of $825,700. On February 27, 2002, Mr. Buxton was also awarded an
option to purchase 182,000 shares of the Company's Common Stock, at an exercise
price of $39.0781 per share (the closing price on the date of grant), which
option expires 10 years after the date of grant. The option vests in three equal
annual installments, commencing February 27, 2003. These payments are in lieu of
any compensation, fees or other benefits to which Mr. Buxton might otherwise be
entitled as a non-employee member of the Board. Mr. Buxton received a bonus in
2001 in the aggregate amount of $196,625. The Company has also agreed to
reimburse Mr. Buxton for all reasonable business expenses incurred by him in the
active performance of his duties as Chairman of the Board, provide him with
office space and secretarial services until December 31, 2005 and provide him
with a vehicle, including covering related expenses, and pay his membership dues
for certain clubs until December 31, 2010.

                                     ITEM 2

               AMENDMENTS TO ARTICLES OF INCORPORATION AND BY-LAWS
                       TO FIX THE SIZE OF THE BOARD AT TEN

         The Board of Directors of the Company has unanimously approved, and is
requesting that the shareholders adopt, an amendment to the Company's Second
Restated Articles of Incorporation and the Company's Third Amended and
Superseding By-Laws to fix the size of the Board of Directors at 10 members.


                                       7



BACKGROUND AND PURPOSE OF PROPOSAL

         Section 1 of Article II of the By-Laws currently provides that the
Board of Directors will consist of not less than three nor more than 15
directors. However, neither Section 1 of Article II of the By-Laws nor the
Minnesota Business Corporation Act contains any specific procedure to fix the
number of directors of the Corporation within such limits. In addition, there
recently has been a general trend in corporate governance to have smaller
boards. The Company's historical practice has also been to have fewer directors
than fifteen. The number of directors was increased from nine to 11 at the 1996
Annual Meeting. Subsequently, the size of the Board of Directors has varied
between nine and 12 members. Board size has fluctuated from year to year as a
result of retirements, resignations and appointments to fill vacancies. The
Board currently has 10 members and, assuming the four nominees for director are
elected, following the Annual Meeting, with Mr. Buxton's retirement, there will
be nine members of the Board of Directors, leaving one vacancy. Keeping the
Board size at 10 members will maintain a Board that is flexible and responsive,
while keeping the Company's cost lower by not expanding the number of members on
the Board.

         Accordingly, the Board of Directors believes it is in the best
interests of the shareholders to amend Section 1 of Article II of the By-Laws to
fix the number of directors of the Corporation at 10. The text of the
resolutions the shareholders are being asked to approve are set forth below:

         RESOLVED, the second sentence of Section 1, Article XI of the Second
         Restated Articles of Incorporation is hereby deleted in its entirety
         and replaced with the following: "The number of directors is hereby
         fixed at ten (10)."

         RESOLVED, the second sentence of Section 1, Article II of the Third
         Amended and Superseding By-Laws is hereby deleted in its entirety and
         replaced with the following: "The Board of Directors shall consist of
         ten (10) directors, who need not be shareholders of the Corporation."

         RESOLVED, the last two sentences of Section 1, Article II of the Third
         Amended and Superseding By-Laws are hereby deleted in their entirety.

         The current and proposed text of the sections of the Second Amended and
Restated Articles of Incorporation and the Third Amended and Superseding By-Laws
to be amended is set forth in Appendix 2.

EFFECT OF PROPOSAL

         The Board of Directors believes that it is desirable to reduce the
potential size of the Board and fix the number of directors at ten. The Board
believes this action will result in a more responsive membership and will
maintain a lower cost with fewer Board members. A smaller Board of Directors
also will enhance the likelihood of continuity and stability in its composition
and, therefore, in the strategic plans and long-term policies adopted by the
Board. Although this change could have the effect of deterring a change in
management in certain circumstances, since the Board could no longer be expanded
to more than 10 without shareholder approval, these changes are not being
proposed for that purpose or in response to any known efforts by any person to
acquire or change the control of the Company.

         In addition, other provisions of the Company's Restated Articles of
Incorporation and By-Laws and the Company's shareholder rights plan may have the
effect of delaying or preventing a change in control of the Company. Although
the Board of Directors does not currently contemplate adopting or proposing for
shareholder approval any additional provisions that may have anti-takeover
effects, the Board does periodically review such provisions and reserves the
right to propose such further actions in the future if, in its view,
circumstances should so warrant. The Board of Directors is not aware of any
existing or planned effort on the part of any party to acquire control of the
Company by means of a tender offer, solicitation of proxies in opposition to
management or by other means.

         If Item 2 is approved by the shareholders, then the amendment to the
Second Restated Articles of Incorporation would become effective upon the filing
of an executed amendment with the Secretary of State of Minnesota, which would
be filed promptly following the Annual Meeting, and the amendments to the
By-Laws would become effective as of the Annual Meeting of Shareholders.


                                       8



VOTE REQUIRED

         Because Item 2 would amend the Company's Second Restated Articles of
Incorporation, this proposal requires the affirmative vote of the holders of at
least 60% of the outstanding shares entitled to vote, provided that the proposal
does not receive a negative vote from holders of more than 25% of the
outstanding voting shares. Abstentions and broker non-votes would have the
effect of votes against the proposal with respect to the 60% approval
requirement, but they do not count as negative votes with respect to the 25%
limitation.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ITEM 2 TO AMEND THE ARTICLES AND
BY-LAWS TO FIX THE SIZE OF THE BOARD OF DIRECTORS AT TEN.

                                     ITEM 3

                  APPROVAL OF THE OMNIBUS STOCK INCENTIVE PLAN
                           FOR SECTION 162(m) PURPOSES

         Shareholders are asked to approve the Omnibus Stock Incentive Plan, as
amended and restated (the "Omnibus Plan") to ensure that performance-based
awards under the plan qualify as such for purposes of Section 162(m) of the
Internal Revenue Code and in order to satisfy New York Stock Exchange guidelines
relating to equity compensation for officers.

         Following is a summary of the material features of the Omnibus Plan.
Capitalized terms have the meanings set forth in the Omnibus Plan, a copy of
which is attached as Appendix 3:

         PURPOSE. To attract and retain top quality executives and key
employees, encourage innovation and growth, reward executives for attainment of
short-term performance objectives and long-term shareholder value, recognize
outstanding performance, encourage executive stock ownership and, in general, to
align management and shareholder interests.

         ELIGIBILITY AND PARTICIPATION. Any key managerial, administrative or
professional employee of the Company (or an affiliate) generally in salary grade
25 or higher who is in a position to make a material contribution to the
continued profitable growth and long term success of the Company (or an
affiliate).

         SHARES AUTHORIZED. The Omnibus Plan has 5,600,000 shares authorized for
issuance, of which no more than 1,120,000 (20%) may be issued as grants in a
form other than stock options. As of December 31, 2001, 2,446,236 shares
remained available for issuance under this plan. Unused shares, such as canceled
or expired options or forfeited shares of restricted stock, are eligible for
future grants.

         OPTIONS. The exercise price of an option, whether incentive stock
options ("ISOs") or non-qualified stock options ("NQSOs"), cannot be less than
the Fair Market Value as of the date of grant. The term of the option is set by
the Compensation Committee at the time of grant, but may not be longer than 10
years. No one participant may receive options or SARS under the Omnibus Plan for
more than 150,000 shares in the aggregate in any calendar year.

         SARS. Participants who have been awarded ISOs may also be award Stock
Appreciation Rights up to the total number of shares the participant could
acquire by exercise of the underlying ISOs, which must expire at the same time
as the underlying ISO and for which the payment amount cannot be more than 100%
of the difference between the exercise price and the Fair Market Value of the
shares subject to the option on the date the SAR is exercised.

         RESTRICTED STOCK AWARDS. The Committee may make awards of restricted
stock (including rights to restricted stock), which are subject to a vesting
period before the participant is entitled to the shares. The Committee
determines the vesting period at the time of grant, but no more than 5% of the
maximum number of shares available under the Omnibus Plan may vest during a
period shorter than three years. The Committee also has the discretion to impose
additional conditions or restrictions on the grant. Beginning in 2001,
restricted stock awards also may be made to officers of the Company and certain
subsidiary presidents (who are nominated by the CEO and approved by the
Committee) under the Time Accelerated Restricted Stock Award Plan (TARSAP),
which has been added to the Omnibus Plan. TARSAP awards are made in addition to
other awards under the Omnibus Plan determined by using an eligibility factor
determined on an individual basis by the Committee. The


                                       9



maximum award available will be an amount equal to the executive's award
eligibility under the Omnibus Plan. Restricted stock awards under the TARSAP
will vest in equal portions in the fifth, sixth and seventh years following the
date of grant. The award may vest earlier, if certain share price performance
goals, as established by the Committee are met, but in no event will more than
one-third of any award vest in any year.

         INCENTIVE COMPENSATION UNITS. The Committee may make awards of ICUs
under the Omnibus Plan. In making an award, the Committee establishes the
specific targets with respect to the corporate performance factors to be met
over a specified Incentive Period (usually three years). The performance factors
currently being used by the Committee are return on invested capital and growth
in operating income. The calculation of the awards for 2001 is described on
pages 21 and 22. Performance factors that also may be used under the Omnibus
Plan include the growth in earnings per share, the average return on equity or
the change in Book Value per share of Stock, all measured over the specified
Incentive Period. The Committee has the discretion to designate additional
factors. The Committee uses the audited financial statements for the fiscal year
in which the Incentive Period ends to determine the value of the ICUs. The
payment may be made in cash, Stock, Restricted Stock or Rights to Restricted
Stock (or any combination), as determined by the Committee at the time of grant.
Shares of stock used in payment of an award are valued as of the date the
Incentive Period ends.

         PERFORMANCE SHARES. The Compensation Committee may make awards of
Performance Shares and Performance Units. At the time of the award the Committee
establishes the terms and conditions applicable to the payment of the award,
including the achievement of target performance objectives. The performance
objectives shall include such financial measures as return on shareholders
equity, growth in earnings per share, return on sales, growth in income and
growth in sales. The achievement of the designated targets is measured over the
Performance Period specified at the date of the award. Awards are paid based on
the degree of attainment of the performance targets. The maximum amount of
compensation a Participant may be granted by reason of a performance award in
any one calendar year is $100,000 (based on the Fair Market Value of the award
on the date of grant). Payment of an award is made within four months following
the end of the Performance Period. The payment may be made in cash, Stock,
Restricted Stock or Rights to Restricted Stock (or any combination), as
determined by the Committee at the time of grant. Shares of stock used in
payment of an award are valued as of the date the Performance Period ends.

         STOCK OWNERSHIP GUIDELINE AWARDS. Stock ownership guidelines for top
management have been established to motivate individual achievement and increase
ownership of the Company's Common Stock. The Committee determined that over a
period of five years, its top management should accumulate and hold Company
stock equal to the following values: Chief Executive Officer -- three to five
times base salary; Senior Corporate Officers -- two to three times base salary;
and other corporate officers and subsidiary presidents -- one to two times base
salary. In the opinion of the Committee, the achievement of ownership levels set
forth will result in executive management being significant shareholders and
will further encourage long-term performance and Company growth.

         The Committee considers incentive grants of restricted stock or rights
to restricted stock based on the increase in ownership during the preceding
year. These restricted stock grants (made under the Omnibus Plan) vest in equal
increments on the third, fourth, and fifth anniversaries of the grant. The size
of the grant is equal to 10% of the increase in common stock during the year if
the annual ownership target is met, limited to 10% of the targeted ownership
level if the targeted ownership level has already been achieved.

         PLAN AMENDMENT, SUSPENSION, MODIFICATION AND TERMINATION. The
Compensation Committee has the right to amend, suspend, modify or terminate the
Omnibus Plan at any time, subject to approval by the Board of Directors.

         TERMINATION OF EMPLOYMENT. In the event a participant dies, becomes
disabled, retires or is otherwise terminated, for cause or otherwise (except for
a "Change of Control," which is described below), the outstanding options or
other awards may be subject to accelerated vesting, a shortening of the exercise
period or termination, all on the terms and conditions set forth in the Omnibus
Plan.

         CHANGE IN CONTROL. If a "Change in Control" (as defined in the
Company's Key Executive Employment and Severance Agreement, effective August 23,
2000) occurs all Options granted to a Participant then employed by Pentair (or
an Affiliate) become fully vested and immediately exerciseable, restrictions on
Restricted Stock and Performance Share awards automatically lapse, rights to
Restricted Stock become fully vested and outstanding


                                       10



ICUs and Performance Units are valued assuming all goals are met and all or a
portion of such award is paid based on when such award was granted. All payments
must be made within 10 days of the Change in Control.

         MODIFICATION OF AWARDS. While the Committee has authority generally to
make modifications to individual awards, including accelerating vesting or
removing restrictions, the Committee does not have discretion to increase the
amount of compensation a Participant could earn by application of preestablished
performance goals and financial measurements relevant to the award, although the
Committee does have discretion to decrease such an award.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ITEM 3 TO APPROVE THE OMNIBUS
STOCK INCENTIVE PLAN FOR 162(M) PURPOSES.

                                     ITEM 4

       APPROVAL OF AN AMENDMENT TO THE EXECUTIVE OFFICER PERFORMANCE PLAN

         Shareholders are asked to approve an amendment to the Executive Officer
Performance Plan ("EOPP") to ensure that awards under the plan continue to
qualify as "performance-based" for purposes of Section 162(m) of the Internal
Revenue Code and in order to satisfy New York Stock Exchange guidelines relating
to equity compensation for officers. The amendment modifies the criteria used to
measure achievement of the performance goals under the plan. The criteria as
amended are described in the paragraph entitled "Performance Goals" set forth
below. If shareholder approval of the amendment is not received, the
Compensation Committee will reconsider the amendment and reconsider the change
to the Performance Goals.

         Following is a summary of the material features of the EOPP.
Capitalized terms have the meanings set forth in the EOPP, a copy of which is
attached as Appendix 4:

         PURPOSE. A primary objective of the Company is to be a top-performing
company by consistently achieving profit performance that is higher than the
performance of comparable companies. The Company has also identified growth as a
key strategy for the long-term success of the business. The return on our
investments, whether to support internal growth and improvements or make
acquisitions, is also a key determinant of our business success and the return
to our shareholders. The Company expects to compensate executive officers for
their performance against key financial measurements in accordance with the
terms of the EOPP.

         ELIGIBILITY AND PARTICIPATION. Key employees in executive positions are
eligible for participation at the discretion of the Compensation Committee.
Participants in the EOPP are not eligible to participate in the Management
Incentive Plan. Currently the Chief Executive Officer is the only participant.
The Compensation Committee may determine that additional executive officers
should be added as participants in the future.

         AWARD AMOUNTS. Annual awards under the EOPP are determined by
multiplying the participant's base salary by his or her bonus opportunity
category percentage (a percentage of base salary based on position) and by the
corporate performance factor. The bonus opportunity category percentage for the
Chief Executive Officer is 100%. Other positions that may qualify in the future,
with the following bonus opportunity category percentages, include: President
and Chief Operating Officer, 80%, Executive Vice Presidents and operating
officers of business segments, 58.5%, and other senior officers, 52%. In
administering the EOPP and in establishing bonus awards, the Committee does not
have the discretion to pay participants more than the bonus amount indicated by
the pre-established goals. The Committee has the discretion and flexibility,
however, based on its business judgment, to reduce such amount.

         PERFORMANCE GOALS. EOPP performance goals and factors are established
by the Compensation Committee prior to or early in each fiscal year. These
performance goals are used to calculate the corporate performance factor that,
in conjunction with the participant's bonus opportunity category percentage,
determines the amount of the bonus awarded to each participant.

         The determination of the corporate performance factor for 2001 is
discussed in the "Compensation of the Chief Executive Officer" section of the
Report of the Compensation Committee.

         For 2002, the Compensation Committee has amended the EOPP to increase
the emphasis on the importance of total capital management. The corporate
performance factor will be determined by multiplying


                                       11



factors for Pentair Value Added ("PVA") and Free Cash Flow. The use of these two
factors reinforces the importance of balancing economically profitable growth
and cash generation.

         For 2002, PVA will be calculated as a target percentage of Net
Operating Profit After Taxes ("NOPAT") less a surcharge against average invested
capital (which is defined as the total of net cash, debt and equity invested in
a relevant business unit, segment or the Company as a whole). For 2002, Free
Cash Flow is equal to net cash provided by operating activities, excluding net
tax-affected interest expense, less capital expenditures. Under the annual bonus
plan, the achievement of (a) Free Cash Flow equal to the target percentage of
NOPAT and (b) PVA generated that equates to the target percentage total business
return (which is defined as the increase in value, based on the annual
performance of a relevant business unit, segment or the Company as a whole),
results in a corporate performance factor of 1.00. The maximum corporate
performance factor is 4.50 and the minimum corporate performance factor is 0.10;
however, there is no bonus if the Company has an operating loss. If the
Company's performance results in a negative PVA the maximum performance factor
is capped at 2.00. Performance between the stated factors is interpolated.

         The target percentages for 2002 established by the Compensation
Committee are discussed in the Report of the Compensation Committee. The
Compensation Committee may further refine the calculation of PVA and Free Cash
Flow in future years to measure the targets it sets in each year. Traditionally,
the achievement of the established targets is measured by applying generally
accepted accounting principles used by the Company in preparing its financial
statements. The EOPP gives the Compensation Committee discretion to use pro
forma results or to exclude the effects of significant transactions or changes
in accounting rules to achieve consistency in measuring results, in the
interests of fairness or to achieve the purposes of the EOPP.

         MAXIMUM AWARD. The maximum annual award is 200% of annual base salary,
but in no event more than $3.5 million.

         PAYMENT. Payment of the bonus amount is made in cash up to the amount
of the participant's annual base salary, with any excess amount awarded in
restricted shares under the Omnibus Plan.

         SHARES AUTHORIZED. The Omnibus Plan, under which EOPP share awards are
issued, has 5,600,000 shares authorized for issuance, of which no more than
1,120,000 (20%) may be issued as grants in a form other than stock options. As
of December 31, 2001, 2,446,236 shares remained available for issuance under the
Omnibus Plan.

         PLAN TERMINATION. The Compensation Committee has the right to terminate
the EOPP at any time, subject to approval by the Board of Directors.

         CHANGE IN CONTROL. If a "Change in Control" (as defined in the
Company's Key Executive Employment and Severance Agreement, effective August 23,
2000) occurs, a participant in the EOPP as of the date of such change in control
is entitled to receive (i) payment of any outstanding but unpaid award for the
prior year and (ii) an award for the fiscal year in effect as of the Change in
Control using the annual base salary rate as in effect immediately before the
Change in Control and assuming the EOPP goals for such year have been attained.
Such amounts are payable within 10 days of the Change in Control. In addition,
certain other provisions or requirements applying to awards under the EOPP are
modified or eliminated in the event of a Change in Control, including the
authority of the Compensation Committee to reduce an award, the minimum
operating income requirement, the requirement of an annual audit and the
requirement that a participant remain employed through the end of the incentive
period.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ITEM 4 TO APPROVE THE AMENDMENT
TO THE EXECUTIVE OFFICER PERFORMANCE PLAN.

                                     ITEM 5

                              APPROVAL OF AUDITORS

         Deloitte & Touche LLP, independent certified public accountants, have
been the auditors for the Company since 1977. They have been retained by the
Board of Directors as the Company's auditors for the current fiscal year, and
shareholder approval of such retention is requested.


                                       12



         Representatives of Deloitte & Touche LLP are expected to attend the
Annual Meeting with the opportunity to make a statement if they so desire, and
they will be available to respond to appropriate questions.

         Upon recommendation of the Audit and Finance Committee, and subject to
ratification by the shareholders at the 2002 Annual Meeting, the Board of
Directors has appointed Deloitte & Touche LLP as independent auditors to examine
the consolidated financial statements of the Company for 2002.

         The enclosed proxy will be voted "For" the proposal to approve
retention of Deloitte & Touche LLP unless a contrary vote or abstention is
indicated. If retention of Deloitte & Touche LLP is not approved by the
shareholders, the Board of Directors will make another appointment effective at
the earliest practicable date.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ITEM 5 TO APPROVE RETENTION OF
DELOITTE & TOUCHE LLP.

                             EXECUTIVE COMPENSATION

COMPENSATION AND HUMAN RESOURCE COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
         During 2001, the Compensation and Human Resource Committee of the Board
of Directors was comprised of Quentin J. Hietpas (Chair through 4/25/01),
Charles A. Haggerty (Chair since 4/25/01), Barbara B. Grogan, Stuart Maitland
and William T. Monahan (beginning 2/01). During 2001, none of the members of the
Committee were officers or employees of the Company and there were no interlock
relationships.

COMPENSATION AND HUMAN RESOURCE COMMITTEE REPORT ON EXECUTIVE COMPENSATION

OVERVIEW
         The Compensation and Human Resource Committee of the Board of Directors
(the "Committee") is responsible for supervising the development of, and making
recommendations to the Board with respect to, the Company's executive
compensation policies. In addition, the Committee makes annual recommendations
to the Board concerning compensation to be paid to the Chief Executive Officer
("CEO") and each of the other executive officers of the Company.

         The Committee also oversees all aspects of the Company's executive
compensation program, including many of the Company's employee benefit plans.
The Company currently maintains a variety of compensation and benefit plans in
which its executive officers may participate including the Omnibus Stock
Incentive Plan (including stock awards granted under the Management Incentive
Plan ("MIP") and Time Accelerated Restricted Stock Award Program ("TARSAP")),
the Employee Stock Purchase and Bonus Plan, the Retirement Savings and Stock
Incentive Plan, the RSIP Sidekick Plan, the Supplemental Executive Retirement
Plan and the Executive Officer Performance Plan ("EOPP"). The Company also
maintains a defined benefit pension plan in which substantially all U.S.-based,
non-bargaining employees, including the Company's executive officers,
participate.

PENTAIR'S COMPENSATION PHILOSOPHY
         The principles guiding the executive compensation program are designed
to ensure a proper linkage between executive compensation and creation of
shareholder value. Goals of the program are:

         (a)      to encourage innovation and growth;

         (b)      to reward executives for top short-term performance and
                  long-term shareholder value;

         (c)      to recognize outstanding performance;

         (d)      to attract and retain top-quality executives and key
                  employees;

         (e)      to encourage executive stock ownership; and thereby

         (f)      to align management and shareholder interests.

         The Company has maintained the philosophy that compensation of the
executive officers should be directly and materially linked to operating results
and stock price performance. To achieve this, compensation is heavily leveraged
through the annual bonuses and long-term equity incentives. The mix of base
salary, bonuses


                                       13



and other benefits reflects the Company's goal of providing average compensation
for average performance and above-average compensation for above-average
performance.

         In order to make its recommendations to the Board concerning executive
officer compensation, the Committee annually reviews and evaluates the Company's
corporate performance and the compensation and equity ownership of its executive
officers. This is done by reviewing salary practices for comparable positions at
other major industrial organizations as disclosed in the Towers Perrin
compensation database, as well as a review of other nationally recognized pay
surveys. These major organizations include companies that the Corporation
competes with for business or executive talent. Many of the companies included
in the Towers Perrin compensation database and national pay surveys are also
listed in the S&P 500 Index and the S&P 400 MidCap Index, the indices included
in the Comparative Stock Performance Graph. The Committee typically retains an
independent compensation consulting firm, such as Towers Perrin, to assist in
the review of executive compensation every other year.

EXECUTIVE COMPENSATION PROGRAM
         The components of the Company's executive compensation program, which
are subject to the discretion of the Committee on an individual basis, include
(a) base salaries, (b) annual cash performance-based bonuses, (c) long-term
performance-based equity incentives, and (d) miscellaneous fringe benefits. All
of these components are comparable to those of companies similar to the Company.

BASE SALARY
         The CEO submits a performance appraisal and recommendation to the
Committee with respect to annual salaries of the executive officers. The
Committee discusses and evaluates the salaries and makes its recommendation to
the Board. Base salary targets for executive positions are set at the 50th
percentile of competitive compensation. An individual performance and experience
factor is applied to the target midpoint to determine each executive's actual
base salary, within a range of +/- 20% of midpoint. For 2001, the salaries of
the named executive officers identified in the Summary Compensation Table are
within the salary targets for each position.

BONUS
         Generally, bonuses are considered for payment to executives and key
employees following the end of each year under the EOPP (see page 11 for
discussion of the EOPP) and the MIP. MIP awards are determined by applying the
following factors to base salary: a bonus opportunity category (40% for
Executive and Senior Vice Presidents; 30-35% for other officers), a corporate
performance factor and an individual performance factor.

         For 2001, the corporate performance factor was determined by
multiplying factors for Simple Pentair Value Added ("SPVA") and Free Cash Flow
("FCF"). The use of these two factors reinforces the importance of balancing
economically profitable growth and cash generation. SPVA is calculated as
follows: earnings before interest and taxes less a 15% surcharge against average
receivables, inventory and payables. FCF for bonus calculation is equal to net
cash provided by operating activities, excluding net tax-affected interest
expense, less capital expenditures. Under the MIP, the achievement of (a) FCF
equal to 6.5% of sales and (b) SPVA generated that equates to a 15% total
business return, results in a corporate performance factor of 1.00. The maximum
corporate performance factor is 4.50 and the minimum corporate performance
factor is 0.21; however, there is no MIP bonus if the Company has an operating
loss. If the Company's performance results in a negative SPVA the maximum
performance factor is capped at 2.00. Performance between the stated factors is
interpolated. The maximum individual cash bonus is 100% of the participant's
annual base salary, with the remainder being paid in shares of restricted stock.
In addition to the corporate performance factor, for executives in charge of
operating segments, a segment performance factor is used and weighted at 75%
versus 25% for the corporate performance factor, to recognize contributions made
at the segment level.

         For 2002, the Company has revised the MIP to emphasize the importance
of total capital management by substituting PVA (Pentair Value Added) for the
SPVA measure. PVA is calculated as follows: Net Operating Profit After Taxes
("NOPAT") less a 10% surcharge against average invested capital. The 2002
corporate performance factor will be a result of the multiplication of factors
for PVA and FCF. FCF for the 2002 bonus calculation will be equal to net cash
provided by operating activities, excluding net tax-affected interest expense,
less capital expenditures. Under the MIP as revised, the achievement of (a) FCF
of 65% of NOPAT and (b) PVA generated that equates to a 15% total business
return, will result in a corporate performance factor of 1.00. The use of these
two factors reinforces the importance of balancing economically profitable
growth and cash generation. The maximum corporate performance factor will remain
4.50 and the minimum corporate performance factor is 0.10


                                       14



and there will be no bonus if the Company has an operating loss. If the
Company's performance results in a negative PVA the maximum bonus remains capped
at 2.00. Performance between the stated factors is interpolated. The maximum
individual cash bonus remains 100% of the participant's annual base salary, with
the remainder being paid in restricted stock.

         In the first quarter of 1999, the Company recorded a special
restructuring charge against continuing operations of $23.0 million ($14.6
million after-tax or $0.34 per share). In the fourth quarter of 2000, the
Company recorded a special restructuring charge against continuing operations of
$24.8 million ($15.9 million after tax, or $0.33 per share). For purposes of the
MIP calculation, costs related to these restructuring activities are being
amortized against the first 24 months of benefits, on a project-by-project
basis. This is a timing difference only for MIP purposes in order to match the
costs with the associated benefits. The bonus calculations for 2001 include a
portion of these restructuring charges. In the fourth quarter of 2001, the
Company recorded a restructuring charge of $41.1 million ($29.8 million
after-tax or $0.60 per share), which will be taken into account for MIP purposes
beginning in 2002.

         The individual performance factor component of the MIP bonus
calculation is determined by the assignment of a numerical factor based on a
supervisor's judgment on attainment of expectations relative to the employee's
function. The CEO submits a performance appraisal and recommendation to the
Committee for executive officers with respect to the individual performance
factor. The Committee approves all MIP awards and has the right to increase or
decrease awards to better accomplish the objectives of the MIP.

         Bonus awards that exceed an amount equal to base salary are paid as a
performance share award under the Omnibus Stock Incentive Plan. The performance
share award is paid in restricted stock, subject to any vesting condition the
Committee may impose.

         The Committee has the discretion to make special awards to retain key
executives or to recognize extraordinary contributions to the welfare,
reputation and earnings of the Company. For 2001, the Company made five such
awards to executive officers, including the CEO and three of the named executive
officers, and each such bonus was made in addition to the MIP or EOPP award
earned by such individual.

LONG-TERM EQUITY INCENTIVES

GRANTS
         Long-term incentive compensation is awarded in the form of restricted
shares, incentive compensation units ("ICUs"), performance shares and stock
options under the Omnibus Stock Incentive Plan ("Omnibus Plan"). All awards are
proposed by the CEO and approved by the Committee. Long-term incentives are
determined by using the average of the 50th and 60th percentile of comparable
grant practices as compiled by the Towers Perrin compensation database. Annual
awards are granted in the form of ICUs (10% for the CEO and 20% for executive
officers) and stock options (90% for the CEO and 80% for executive officers).

         Restricted stock may be awarded to such individuals as described in the
section entitled "stock ownership guidelines" below; as an award to a new
executive officer; as the form of payment of performance shares; or in payment
of MIP or EOPP bonuses in excess of annual base salary. Restricted stock awards
also may be made to officers of the Company and certain subsidiary presidents
(who are nominated by the CEO and approved by the Committee) under the TARSAP,
which has been added to the Omnibus Plan. TARSAP awards are made in addition to
other awards under the Omnibus Plan and are determined by using an eligibility
factor set on an individual basis by the Committee. The maximum award available
is an amount equal to the executive's award eligibility under the Omnibus Plan.
Restricted stock awards under the TARSAP vest in equal portions in the fifth,
sixth and seventh years following the date of grant. The award may vest earlier,
if certain performance goals, such as share price targets, are met, but in no
event will more than one-third of any award vest in any year.

         The Committee is authorized to grant stock options and performance
share awards upon attainment of certain performance criteria that are based on
the Company's long-term objectives. The Black-Scholes Model is used to determine
stock option grant values.

         Stock options can be granted for terms up to 10 years. Beginning with
stock options granted in 1998, if the option holder exercises the stock option
during the first five years of the option term by tendering to the Company
common shares owned by that person, the Committee can grant to such person, an
option ("Reload Option") to purchase common shares equal to the number of shares
tendered. The Reload Option may be


                                       15



exercised during the remaining term of the original stock option period. The
Reload Option exercise price is equal to the market price per share on the date
the shares are tendered.

         In addition, in 2001, the Committee determined that, in the interests
of retaining key management personnel, the Committee would provide additional
grants of option awards to certain executives, as determined by the Committee on
an individual basis. These individuals were eligible to receive options for
additional shares up to an amount equal to 50% of their grant eligibility for
2001.

         The total Omnibus Plan awards for 2001 for all executive officers as a
group, including the CEO and named executive officers, amounted to 1,912,998
ICUs, 683,500 stock options, 5,584 restricted shares, which were awarded for
achievement of stock ownership guidelines, and 180,000 restricted shares, which
were awarded under the TARSAP. Grants for the named executive officers are shown
in the Summary Compensation Table (page 19) and the Option/SAR grant table (page
20).

PAYOUTS
         Payouts on ICUs in 2001 which related to ICU grants in 1998 were based
upon the Company's three year average Return On Invested Capital (ROIC) and
three year average Operating Income. Payouts in 2001 for the named executive
officers are shown in the LTIP Payout column on the Summary Compensation Table
(page 19). For retention purposes, in 2001, the Compensation Committee increased
the dollar value of each ICU paid out from $.71 to $1.00.

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

         The base salary, annual bonus and long-term equity incentives paid to
Mr. Hogan in 2001 were generally determined in accordance with the guidelines
described above, and his compensation is comprised of the same elements as for
all executive officers. Mr. Hogan became CEO effective January 1, 2001.

         The Committee has a formal rating process for evaluating the
performance of the Chief Executive Officer. The rating process includes a
self-evaluation rating by the CEO, after which each Board member completes an
evaluation and rating with commentary. The Chairman of the Committee provides a
consolidated rating report and chairs a discussion with the Board members
without the CEO present. From that discussion, the performance rating is
finalized and the Committee Chairman is instructed to review the final rating
results and commentary with the CEO. This then translates into a personal
development plan for the following year. The first such review for Mr. Hogan was
held in December 2001.

         Mr. Hogan's base salary was $625,000 in accordance with the Committee's
guideline of establishing the base salary at the market compensation rate for
the CEO at the 50th percentile for companies at a comparable size as projected
based on the 2000 performance. This resulted in a 39% increase in Mr. Hogan's
base salary over 2000, reflecting his promotion from COO to CEO.

         Mr. Hogan's bonus was determined under the EOPP. During 2001, the
Chairman and the Chief Executive Officer were the only eligible officers
participating in the EOPP. EOPP awards are determined based on the participant's
bonus opportunity and a corporate performance factor. For 2001, the maximum
individual bonus for the CEO was 200% of his annual base salary, but in no event
more than $3,500,000. In administering the EOPP and in establishing bonus awards
thereunder, the Committee does not have the discretion to pay participants more
than the bonus amount indicated by the preestablished goals. The Committee has
the discretion and flexibility, however, based on its business judgment, to
reduce this amount.

         For 2001, the corporate performance factor was determined by
multiplying factors for SPVA and FCF. The use of these two factors reinforces
the importance of balancing economically profitable growth and cash generation.
SPVA is calculated as follows: earnings before interest and taxes less a 15%
surcharge against average receivables, inventory and payables. FCF for bonus
calculation is equal to net cash provided by operating activities, excluding net
tax-affected interest expense, less capital expenditures. Under the EOPP, the
achievement of (a) FCF equal to 6.5% of sales and (b) SPVA generated that
equates to a 15% total business return, results in a corporate performance
factor of 1.00. The maximum corporate performance factor is 4.50 and the minimum
corporate performance factor is 0.21; however, there is no EOPP bonus if the
Company has an operating loss. If the Company's performance results in a
negative PVA the maximum performance factor is capped at 2.00. Performance
between the stated factors is interpolated.


                                       16



         Mr. Hogan's bonus was calculated using the formula described above. For
2001, SPVA declined by $68.2 million (including the impact of amortizing the
1999 and 2000 restructuring charges) and FCF was 8.3% of net sales, resulting in
a corporate performance factor of 0.325. The Committee used his base salary of
$625,000, his bonus opportunity category of 100%, and the corporate performance
factor of 0.325 to obtain his bonus amount. In accordance with the terms of the
EOPP, the bonus amount of $203,125 was paid in cash. The Committee exercised its
discretion to make special awards to retain key executives or to recognize
extraordinary contributions to the welfare, reputation and earnings of the
Company and awarded a bonus of $200,000 to Mr. Hogan, in addition to the EOPP
bonus. Mr. Hogan's Omnibus Plan grants were computed based on the average of the
50th and 60th percentile of the Towers Perrin compensation database for
comparable grant practices. He was granted 284,400 ICUs and 174,000 stock
options in 2001.

         For 2002, the Company has revised the EOPP in the same manner as the
MIP described above to further emphasize the importance of capital management by
substituting PVA for the SPVA measure. PVA and FCF will be measured in the same
manner as described for the MIP.

STOCK OWNERSHIP GUIDELINES
         Stock ownership guidelines for top management have been established to
motivate individual achievement and increase ownership of Pentair Common Stock.
The Committee determined that over a period of five years, its top management
should accumulate and hold Company stock equal to the following values: Chief
Executive Officer -- three to five times base salary; Senior Corporate Officers
-- two to three times base salary; and other corporate officers and subsidiary
presidents -- one to two times base salary. In the opinion of the Committee, the
achievement of ownership levels set forth will result in executive management
being significant shareholders and will further encourage long-term performance
and Company growth.

         The Committee will consider making incentive grants of restricted stock
based on the increase in ownership during the preceding year. These restricted
stock grants (made under the Omnibus Plan) vest in equal increments on the
third, fourth, and fifth anniversaries of the grant. The size of the grant is
equal to 10% of the increase in common stock during the year if the annual
ownership target is met, limited to 10% of the targeted ownership level if the
targeted ownership level has been achieved. In 2001, restricted stock awards of
6,893 were granted under these guidelines to all key employees.

COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(m)

         Section 162(m) of the Internal Revenue Code generally disallows a tax
deduction to public companies for compensation over $1 million paid to each of
the corporation's Chief Executive Officer and the four other most highly
compensated officers. Qualifying performance-based compensation is not subject
to the deduction limit if certain requirements are met. The Company's policy is
to maximize the deductibility of executive compensation so long as the
deductibility is compatible with the more important objectives of retaining
executives and maintaining competitive and motivational performance-based
compensation. The shareholders are being asked to approve the Omnibus Stock
Incentive Plan and an amendment to the EOPP this year, all to comply with
Section 162(m) requirements. Under current interpretations of Section 162(m),
EOPP bonus awards and most Omnibus Plan awards of stock options, SARs, ICUs,
performance shares and performance units should not be subject to the $1,000,000
deduction limit assuming receipt of shareholder approval and compliance with all
other aspects of Section 162(m); however, some awards may not meet the
requirements to be exempt from 162(m).

                       COMPARATIVE STOCK PERFORMANCE GRAPH

         The following graph sets forth the cumulative total shareholder return
on the Company's Common Stock for the last five fiscal years, assuming the
investment of $100 on December 31, 1996 and the reinvestment of all dividends
since that date to December 31, 2001. The graph also contains for comparison
purposes the S&P 500 Index and the S&P MidCap 400 Index.

         By virtue of its market capitalization, Pentair is a component of the
S&P MidCap 400 Index. On the basis of the Company's size and diversification of
businesses, a readily identifiable peer group has not been found. It is our
opinion the S&P MidCap 400 Index is an appropriate comparison. The Company has
evaluated other


                                       17



published indices, but has determined that the results are skewed by one or two
large companies included in the indices. We believe such a comparison would not
be meaningful.

         equal installments on the third, fourth and fifth anniversaries of the
         grant, based solely on the continued employment of the recipient by the
         Company. The value of restricted stock awards reflected in the table is
         based on the closing market price of the Common Stock on the date of
         grant. As of December 31, 2001, the following restricted stock awards
         (not yet earned) were held by each of the named executives (based on
         12/31/01 closing price of $36.5156): Hogan 87,575 shares or $3,197,854;

         perquisite program available to certain executives for the
         reimbursement of certain business-related expenses, including
         automobile expenses, membership fees, professional fees (including tax
         preparation costs) and out-of-pocket medical expenses. The program
         includes an annual benefit of up to $20,000, plus a one-time benefit of
         up to $50,000 for certain membership fees.
(g)      Approximately $416,000 of this amount represents reimbursement of
         relocation expenses.

         The ultimate payout value of each ICU is determined based on the
Company's operating income (OI) growth and return on invested capital (ROIC)
averaged over the three-year period. The target payout shown in the table is
based on annual OI growth of 10% and annual ROIC of 20% which results in a value
per ICU of $1.73. If over the three-year period there is no OI growth or ROIC is
less than 15%, the value per ICU will be $0. The maximum value per ICU is $4.76.
The following matrix shows the ICU values based on the OI growth and ROIC.

RETIREMENT BENEFIT PLANS

         The Company maintains a tax-qualified defined benefit pension plan
covering substantially all nonbargaining U.S. employees and an excess benefit
plan covering highly-paid employees. Benefits under each plan are based on a
participant's high five year average eligible earnings which generally include
salary and bonus.

         The Company maintains an unfunded, nonqualified Supplemental Executive
Retirement Plan (SERP) for corporate officers and subsidiary presidents. The
annual retirement benefit payable under the SERP at age 65 is equal to 50% of
the participant's high three year average eligible earnings reduced by 100% of
the annual primary Social Security benefit and further reduced by age 65
benefits payable under qualified pension plans sponsored by the Company and
previous employers of the participant.

         Effective January 1, 1999 the Company amended the SERP to provide an
annual retirement benefit which, expressed as a lump sum, is equal to the
product of 15 percentage points for each year of service times the high five
year average eligible earnings with no reductions for Social Security or
qualified pension benefits. SERP benefits are payable as early as the attainment
of age 55 and completion of five years of service in the new plan and are
converted into and received in the form of a term certain or joint and survivor
annuity.

         The following estimated aggregate amounts are payable from the
qualified pension (as a life annuity), excess plan and SERP (as a fifteen year
term annuity) upon retirement to the named executive officers, assuming
retirement at age 65 and each final salary is the same as that at January 1,
2002: Hogan $397,361; Harrison $270,855; Feraco $120,345; Cathcart $369,038;
Schrock $226,859.

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS

         The Company has entered into an Employment Agreement with Richard J.
Cathcart, the President and Chief Operating Officer of the Water Technologies
segment. The Employment Agreement provides that in the event Mr. Cathcart's
employment is terminated at any time prior to his normal retirement date (as
determined under the primary defined benefit pension plan applicable to Mr.
Cathcart), unless terminated "For Cause" as defined in the agreement, then Mr.
Cathcart is entitled to receive certain severance benefits. Prior to reaching
age 62, he is entitled to a payment of three times his annual cash compensation,
at age 62 he is entitled to an amount equal to his annual cash compensation and
from age 63 on there is no cash payment amount. The amount of this payment is
subject to reduction if the average performance of the Water Technologies
segment (or any other segment for which Mr. Cathcart has responsibility during
the applicable period) for the three fiscal years preceding termination does not
meet the specified criteria. Mr. Cathcart is also entitled to receive
outplacement services, medical benefits, full vesting in the accrued benefit
under the Supplemental Executive Retirement Plan plus any additional benefits he
would have received if employment had continued until age 62. In addition, the
agreement provides for the vesting of restricted stock awards and stock options,
as well as a formula for calculating payment of outstanding performance-based
awards. The agreement also contains a covenant against competition from Mr.
Cathcart.

         Approximately 20 key corporate executives and business unit leaders
(including the executive officers) have entered into agreements with the Company
that provide for contingent benefits in the event of a change in control of the
Company (except in certain very limited circumstances). Such benefits include:

         a.       bonus awards for the year in question to be made under the
                  Management Incentive Plan;


                                       22



         b.       immediate vesting of all unvested stock options, termination
                  of all restrictions on shares issued under the Omnibus Plan,
                  and payment for ICU's and performance units without regard to
                  the plans' forfeiture provisions;

         c.       reimbursement of any excise taxes triggered by payments to the
                  executive;

         d.       the cost of an executive search agency;

         e.       directors and officers liability insurance coverage;

         f.       short-term replacement coverage for Company-provided group
                  medical, dental, and life insurance policies;

         g.       amount of non-vested benefits under any of the Company's
                  tax-qualified deferred compensation plans;

         h.       the accelerated accrual and vesting of benefits under the
                  Supplemental Executive Retirement Plan (for those executives
                  who have been made participants of such plan);

         i.       severance pay equal to 300% (for the CEO), 250% (for the
                  Company's other executive officers and business unit
                  presidents) or 200% (for all other applicable executives) of
                  annual compensation;

         j.       guaranteed salary, benefit and bonus levels for continuing
                  employees for up to a three-year period; and

         k.       reimbursement of the executive's legal expenses in the event
                  of a dispute with the Company arising out of the agreement.

         In addition, the Omnibus Plan permits the Compensation and Human
Resource Committee, upon a change in control of the Company, to cancel all
outstanding options granted under the plan, whether or not exercisable, and
authorize payment of the "spread" between the exercise price of the options and
the then current market value of the underlying stock. The agreement requires
the executive to devote his or her best efforts to the Company or its successor
during the three-year period, to maintain the confidentiality of Company
information during and following employment and to refrain from competitive
activities for a period of one year following termination of employment with the
Company or its successor.

       REPORT OF THE AUDIT AND FINANCE COMMITTEE OF THE BOARD OF DIRECTORS

         The Audit and Finance Committee of the Board of Directors is
responsible for selecting auditors, ensuring the fiscal integrity of the Company
and establishing and reviewing internal controls. The Audit and Finance
Committee adopted a Charter of its responsibilities on February 23, 2001, which
is attached as Appendix 1 to this Proxy Statement. The Audit and Finance
Committee is comprised of the following directors:

                   *subject to election at the Annual Meeting

         In accordance with the recently adopted SEC and NYSE standards for
independence of Audit and Finance Committee members, the Board of Directors
considers all of the members of the Audit and Finance Committee to be
independent. None of the members of the Audit and Finance Committee were
officers or employees of the Company during or prior to 2001, or had a
relationship with the Company that would, in the


                                       23



opinion of the Board of Directors, interfere with the exercise of his or her
independence from management and the Company. All of the members of the Audit
and Finance Committee have substantial experience in financial matters and
business operations.

         The Audit and Finance Committee has (i) reviewed and discussed the
Company's audited financial statements with management; (ii) discussed with the
Company's independent auditors, Deloitte & Touche LLP, the matters required to
be discussed by Statement on Auditing Standards No. 61; (iii) received from the
auditors disclosures regarding the auditors' independence in accordance with
Independence Standards Board Standard No. 1 and discussed with the auditors the
auditors' independence; and (iv) considered whether the level of non-audit
services provided by Deloitte & Touche LLP is compatible with maintaining the
independence of its auditors.

addition, the Audit and Finance Committee, through its Chair, reviewed the
Company's 2001 quarterly results prior to public release.

                           CHARTER OF RESPONSIBILITIES
                                       FOR
                           AUDIT AND FINANCE COMMITTEE
                                       Of
                                  Pentair, Inc.
                               Board of Directors


The Audit and Finance Committee (the "Committee") has been appointed by the
Board of Directors to assist the Board in supervising the financial and legal
compliance of the Company. The principal responsibility of the Committee is to
monitor the integrity of the financial statements of the Company and the
independence and performance of the Company's internal and external auditors.
The Committee also will work in cooperation with the Company's legal counsel to
monitor compliance with applicable legal requirements when the risk of
non-compliance might have an adverse impact on the Company's financial condition
or results of operations.

The Committee shall consist of at least three directors, all of whom shall be
independent and financially literate, and at least one of whom shall possess
financial or accounting expertise, as determined by the Board of Directors. A
director shall be considered independent if he or she meets the requirements
established by the New York Stock Exchange for Audit and Finance Committee
independence and will submit an annual statement to the Board confirming
compliance with these independence requirements. The members of the Committee
will be appointed by the Board on the recommendation of the Nominating and
Governance Committee.

The Committee shall have the authority to retain special legal, accounting or
other consultants to advise the Committee. The Committee may request any officer
or employee of the Company or the Company's outside counsel or independent
auditor to attend a meeting of the Committee or to meet with any members of, or
consultants to, the Committee.

A.       With regard to the Company's financial statements and accounting
         practices and policies, the Committee shall:

         *        Meet with management to review the annual audited financial
                  statements and discuss major issues regarding accounting and
                  auditing principles and practices as well as the adequacy of
                  internal controls that could significantly affect the
                  Company's financial statements.

         *        Review significant financial reporting issues and judgments
                  made in connection with the preparation of the Company's
                  financial statements.

         *        Review with management and the independent auditor the
                  Company's quarterly financial statements prior to the release
                  of quarterly earnings.

         *        Meet periodically with management to review the Company's
                  major financial risk exposures and the steps management has
                  taken to monitor and control such exposures.

         *        Review major changes to the Company's accounting principles
                  and practices as suggested by the independent auditor,
                  internal auditors or management.

B.       With regard to the independent certified public accountants (external
         auditors) responsible for rendering opinions reflecting proper
         compliance with generally accepted accounting principles and various
         financial accounting standards, the Committee shall:

         *        Review and recommend to the Board the appointment or retention
                  of an independent auditor, which firm is ultimately
                  accountable to the Committee and the Board.

         *        Review and approve the independent auditor's audit plan
                  including scope, staffing, timing of work and audit fees.


                                 Appendix 1 - 1



         *        Ensure that the external auditors submit on a periodic basis
                  to the Committee a formal written statement delineating all
                  relationships between the auditors and the Company; actively
                  engage in a dialogue with the external auditors with respect
                  to any disclosed relationships or services that may impact the
                  objectivity and independence of the external auditors; and
                  recommend that the Board of Directors take appropriate action
                  in response to the external auditors' report to satisfy itself
                  of their independence.

         *        Discuss with the independent auditor the matters required to
                  be discussed by Statement on Auditing Standards No. 61
                  relating to the conduct of the audit.

         *        Review independent auditor's letter reports regarding the
                  Company's internal controls and other observations and
                  recommendations and management's responses.

C.       With regard to the Company's internal audit practices, the Committee
         shall:

         *        Perform a general oversight function assuring adequate
                  competent staff and sufficient internal control policies to
                  ensure the integrity of the Company's financial reporting
                  process.

         *        Review the performance of the internal audit department.

         *        As appropriate, review significant reports to management
                  prepared by the internal audit department and management's
                  responses.

D.       The Committee shall also:

         *        Review and approve the report required by the rules of the
                  Securities and Exchange Commission to be included in the
                  Company's annual proxy statement regarding the activities of
                  the Committee.

         *        Review with the Company's General Counsel legal matters that
                  may have a material impact on the financial statements, the
                  Company's compliance policies and any material reports or
                  inquiries received from regulators or government agencies.

         *        Meet at least annually with the Company's financial
                  management, the senior internal audit staff and the
                  independent auditor in separate executive sessions, as needed.

         *        The Committee shall review and reassess at least annually the
                  adequacy of this Charter and recommend any proposed changes to
                  the Board for its review and approval and submit required
                  certifications to the appropriate exchanges.

While the Committee has the responsibilities and power set forth in this Charter
delegated to it by the Board, it is not the duty of the Committee to plan or
conduct audits or to determine that the Company's financial statements are
complete and accurate and are in accordance with generally accepted accounting
principles. This is the responsibility of management and the independent
auditor. Nor is it the duty of the Committee, separate from the Board, to
conduct investigations, to resolve disagreements, if any, between management and
the independent auditor or to assure compliance with laws and regulations and
the Company's Code of Conduct.

SECTION 1. BACKGROUND AND PURPOSE

         1.1. Background. Pentair, Inc. ("Pentair") maintains a comprehensive
equity compensation incentive plan to award long-term equity incentives which
tie the compensation of executives and key managerial employees to Pentair
operating results. In particular, this Plan is designed to attract and retain
top quality executives and key employees, encourage innovation and growth,
reward executives for attainment of short-term performance objectives and
long-term shareholder value, recognize outstanding performance, encourage
executive stock ownership and, in general, to align management and shareholder
interests. Pentair established the Plan in 1990 by combining its then separate
equity compensation plans into one plan to achieve administrative consistency
and greater flexibility in structuring equity compensation awards.

         1.2. Restatement of Plan. Pentair amended and restated this Plan to
authorize additional shares of Stock and ICUs with which to make grants under
the Plan, clarify certain administrative practices and bring the Plan into
compliance with Code requirements enacted since the Plan's adoption. The amended
and restated Plan was adopted on February 14, 1996, subject to shareholder
approval, and applies to all equity compensation grants made after that date.
This amended and restated plan extends until February 14, 2006.

         1.3. 2001 Amendments. Pentair is amending the Plan, effective February
14, 2001, to authorize additional shares of Stock with which to make grants
under the Plan, implement a cap on the amount of authorized shares of Stock
available for various types of Stock awards, other than Options, and clarify the
authority of the Committee to amend outstanding grants.

                                 Appendix 3 - 2



         (b) Unused Shares. Any shares of Stock subject to an Option which is
canceled, expires or otherwise terminates without having been exercised in full
(unless such cancellation is due to the exercise of a related SAR), or any
shares of Restricted Stock, Rights to Restricted Stock or Performance Shares
which are forfeited, shall again be available for grants or awards under the
Plan.

         3.2. Incentive Compensation Units. The maximum number of Incentive
Compensation Units which may be awarded under the Plan is 4,000,000, subject to
adjustment as provided in this Section 3.2 and in Section 3.3. If an ICU is
awarded, but is forfeited or otherwise terminates without payment having been
made to the Participant, then such ICU shall again be available for awards under
the Plan.

         3.3. Antidilution. In the event of a change in the number or class of
outstanding shares of Stock by reason of a stock dividend or split,
recapitalization, reclassification, merger, consolidation, or other similar
corporate change, the number of shares of Stock as to which grants of Options or
other awards under the Plan may be made, and the number of ICUs available for
award under the Plan, shall be adjusted proportionately to the nearest whole
share or unit. Any such action shall be within the discretion of the Committee,
whose determination shall be conclusive.

         If such an adjustment is made with respect to shares then subject to an
Option, the number of shares and the Option price per share shall be adjusted
proportionately so the aggregate exercise price of such Option shall not change.

SECTION 4. STOCK OPTIONS

         4.1. Granting Options. Participants may be granted ISOs, SARs or NQSOs.
No one Participant shall be granted, in the aggregate, Options or SARs on more
than 150,000 shares in any calendar year. Solely for purposes of determining the
number of Options or SARs available for grant to an individual in any calendar
year, Options which are canceled or repriced shall be counted against this
annual maximum to the extent required by applicable regulations.

         4.2. Option Terms and Conditions. (a) Grant of Option. Except as
otherwise limited by the Plan, the Committee shall have the discretion to grant
to a Participant any number or type of Options at any time, and subject to such
terms and conditions as the Committee may determine.

         (b) Exercise Limit. With respect to Options designated as ISOs at the
time of grant, to the extent the aggregate Fair Market Value of Stock,
determined as of the date of grant, with respect to which ISOs are first
exercisable during any single calendar year exceeds $100,000, or such other
limit as shall be allowed under the Code, such Options shall be treated as
NQSOs. In applying this limit Options shall be taken into account in the order
granted.

         (c) Option Price. The Option price of an ISO or NQSO shall be not less
than Fair Market Value as of the date of grant. If an ISO is granted to a
Significant Shareholder, the Option price shall be not less than 110% of Fair
Market Value on the date of grant.

         (d) Term of Option. Each Option shall expire at the time specified by
the Committee when granting the Option. The Committee may not fix a term which
is shorter than required under any applicable state or federal law, nor longer
than ten (10) years from the date of grant. With respect to a Significant
Shareholder, the Committee may not fix a term which is longer than five (5)
years from the date of grant. An Option term may extend beyond the Plan's
termination date.

         (e) Manner of Exercise. To exercise an Option, whether partially or
completely, the Participant shall give written notice to Pentair in such form
and manner as the Committee may prescribe. Payment for Stock to be acquired by
the exercise of an Option must accompany the written notice of exercise.

         (f) Payment. (1) General. Full payment for all Stock to be acquired
upon the exercise of an Option, together with an amount sufficient to satisfy
applicable federal, state or local withholding taxes, shall be made at the time
such Option, or any part thereof, is exercised, and no Stock certificate shall
be issued until such payment has been made. Payment may be made in cash or in
such other form as is acceptable to the Committee, provided that in the case of
an ISO, no form of payment shall be allowed which would prevent the Option from
qualifying as such within the meaning of Code section 422.


                                 Appendix 3 - 3



         (2) Payment with Options. The Participant, in lieu of or in combination
with a payment in cash, may transfer to Pentair a sufficient number of
outstanding Options as will pay all applicable withholding tax liability
incurred on exercise of the Option. For this purpose, the Participant may use
only Options having an exercise price less than Fair Market Value on the date
such Options are transferred or exercised, and the value of such any Option so
transferred shall be the difference between its then exercise price and Fair
Market Value. Transfer of an Option for payment of taxes shall be considered
exercise of the Option.

         (3) Payment with Stock. Subject to such Code requirements as are
relevant to ISOs, a Participant, in lieu of or in combination with a payment in
cash, may transfer to Pentair a sufficient number of shares of Stock to satisfy
all or any part of the Option price and applicable withholding taxes. Such Stock
may be Stock already owned by the Participant or, in the case of an NQSO, Stock
to be acquired by exercise of the Option. For this purpose, the value of the
Stock shall be Fair Market Value as of the date of exercise. Where payment is
made in whole or in part by Stock, the Participant may not transfer fractional
shares of Stock or shares of Stock with an aggregate Fair Market Value in excess
of the Option price plus applicable withholding taxes.

         (4) Interim Broker Loan. The Committee may arrange through a stock
brokerage or other similar agent, a loan to a Participant of some or all of the
funds needed to exercise an Option. Upon application for such loan and receipt
of written notice of exercise of an Option from a Participant, the broker will
pay to Pentair the amount requested by the Participant to pay the Option
exercise price and applicable withholding taxes. Pentair will promptly deliver
to such broker a certificate representing the total number of shares of Stock to
be acquired by exercise of said Option. The broker will then sell part or all of
these shares and pay to the Participant the proceeds from the sale, less the
loan principal and any interest charged thereon from the date the broker
received the notice of exercise until the date the broker is repaid.

         (5) Other Payment Methods. The Committee may, in its discretion,
authorize payment by other methods or forms within the limitations imposed by
the Plan and applicable state or federal law.

         (g) No Tandem Options. No ISO granted under this Plan shall contain
terms which would limit or otherwise affect a Participant's right to exercise
any other Option, nor shall any NQSO contain terms which will limit or otherwise
affect the Participant's right to exercise any other Option in such a manner
that an Option intended to be an ISO would be deemed a tandem option.

         4.3. Stock Appreciation Rights. (a) Grant of Stock Appreciation Rights.
The Committee may grant Stock Appreciation Rights ("SARs") to Participants who
have been granted ISOs. These SARs may relate to any number of shares, up to the
total number of shares the Participant could acquire by exercise of the
underlying ISOs. An SAR shall expire no later than the expiration date of the
underlying ISO, and the amount paid shall not be more than 100% of the
difference between the Option price and Fair Market Value of the Stock subject
to the Option, determined on the date the SAR is exercised.

         (b) Exercise. Stock Appreciation Rights may be exercised at the same
time, to the same extent and subject to the same conditions as the related ISO,
and only when the Fair Market Value of the Stock subject to the ISO exceeds the
Option price. The exercise of an SAR shall cancel the related ISO; the exercise
of an ISO shall cancel a related SAR.

         (c) Payment of Stock Appreciation Rights. Upon exercise of an SAR, the
Participant shall be paid in cash, Stock, Rights to Restricted Stock, Restricted
Stock, or a combination thereof, as the Committee shall determine at the time of
grant. If payment is made in Stock, Rights to Restricted Stock or Restricted
Stock, the shares shall be valued at Fair Market Value on the date the SAR is
exercised.

         4.4. Issuance of Certificates. (a) Delivery. As soon as practicable
after either the exercise of an Option and the delivery of payment therefor, or
the exercise of an SAR which is to be paid in Stock, Rights to Restricted Stock
or Restricted Stock, Pentair shall:

         (i)      if Stock is to be issued due to the exercise of an Option,
                  record in the name of the Participant a number of certificated
                  or uncertificated shares equal to the number of shares
                  acquired by the Participant through exercise of the Option;

         (ii)     if payment is to be made in Restricted Stock, record in the
                  name of the Participant a number of nonnegotiable certificated
                  or uncertificated shares equal to the number of shares of
                  Restricted Stock acquired; and


                                 Appendix 3 - 4



         (iii)    if payment is to be made in Rights to Restricted Stock,
                  establish and maintain a separate written account for each
                  Participant and record in such account the number of Rights to
                  Restricted Stock so acquired.

         Consistent with applicable state or federal law, the Committee may fix
a minimum or maximum period of time during which a Participant may not sell any
such Stock or Restricted Stock, or obtain Restricted Stock in lieu of a Right to
Restricted Stock.

         (b) Designation. Shares acquired pursuant to the exercise of an ISO
shall be designated as such on the stock transfer records of Pentair, to the
extent the value of such shares does not exceed the exercise limit contained in
Section 4.2(b). Shares acquired by exercise of an Option which exceed this
exercise limit shall be designated on Pentair's stock transfer records as shares
acquired pursuant to the exercise of an NQSO. For purposes of this exercise
limit, the designation of shares as acquired pursuant to the exercise of an ISO
or NQSO shall be subject to change as permitted by applicable Code provisions.

SECTION 5. RESTRICTED STOCK AND INCENTIVE COMPENSATION UNITS

         5.1. Restricted Stock Awards (a) Written Agreement. Each award of
Restricted Stock or Rights to Restricted Stock shall be evidenced by a written
agreement, executed by the Participant and Pentair. Such agreement shall specify
the number of shares of Restricted Stock or the number of Rights to Restricted
Stock awarded and any terms and conditions the Committee may require on such
award.

         (b) Restriction Period. At the time of an award of Restricted Stock or
Rights to Restricted Stock, the Committee shall fix a period of time
("Restriction Period") during which such restrictions as are imposed by the
Committee shall remain in effect; provided that the number of shares of Stock
with respect to which the Committee may make an award which fixes a Restriction
Period of less than three (3) years shall not exceed five percent (5%) of the
maximum number of shares available under the Plan. Such restrictions shall lapse
upon expiration of the Restriction Period, or sooner if otherwise provided in
the Plan.

         (c) Restrictions. In addition to such other restrictions as the
Committee may impose at grant, each share of Restricted Stock or Right to
Restricted Stock shall be subject to the following restrictions:

                  (i)      Neither Restricted Stock nor Rights to Restricted
                           Stock may be sold, assigned, transferred, pledged,
                           hypothecated, or otherwise disposed of during a
                           Restriction Period.

                  (ii)     Except as otherwise herein provided, unless the
                           Participant remains continuously employed by Pentair
                           or an Affiliate until the conditions for the removal
                           of such restrictions as the Committee may impose have
                           been satisfied, Restricted Stock and Rights to
                           Restricted Stock shall be forfeited and returned to
                           Pentair, and all rights of a Participant to receive
                           Restricted Stock or vest in Rights to Restricted
                           Stock shall terminate without any payment or
                           consideration by Pentair.

         (d) Recordkeeping. As soon as practicable after the execution of the
written agreement required by Section 5.2(a), Pentair shall:

                  (i)      for awards of Restricted Stock, record in the name of
                           the Participant a number of nonnegotiable,
                           certificated or uncertificated shares equal to the
                           number of shares of Restricted Stock awarded; and

                  (ii)     for awards of Rights to Restricted Stock, establish
                           and maintain a separate written account for each
                           Participant and record in such account the number of
                           Rights to Restricted Stock awarded.

         (e) Dividends. Dividends declared with respect to shares of Restricted
Stock shall be paid in cash to the Participant as and when declared, or as
otherwise determined by the Committee. Where Rights to Restricted Stock are
awarded, the Committee shall determine whether amounts equivalent to dividends
declared on Stock subject to an award of Rights to Restricted Stock shall be
paid when the dividends are declared, or as


                                 Appendix 3 - 5



otherwise determined by the Committee. Dividends, regardless of when paid, shall
be subject to all applicable withholding taxes.

         5.2. Incentive Compensation Units. (a) Award Agreements. Each ICU award
shall be evidenced by a written agreement, executed by the Participant and
Pentair, which shall specify the number of ICUs awarded and contain such other
terms and conditions as the Committee may require.

         (b) ICU Account. Pentair shall establish and maintain a separate
account ("ICU Account") for each Participant and record in such accounts the
number of ICUs awarded to each Participant. The number of ICUs which may be
realized by each Participant may be adjusted by any conditions specified by the
Committee in the award agreement. The maintenance of an ICU Account is
principally a bookkeeping function and does not entitle a Participant to realize
on an ICU award.

         (c) Earning an ICU Award. (1) General. The ability of a Participant to
realize on an ICU award shall be determined by achievement of specific corporate
performance factors over the designated Incentive Period. The maximum amount of
compensation per ICU payable to a Participant in any calendar year by reason of
an ICU award shall not exceed twice the growth in Book Value, determined
pursuant to Section 5.2(d), over the applicable Incentive Period.

         (2) Incentive Period. At the time of award, the Committee shall fix the
Incentive Period during which the Participant must remain continuously employed
by Pentair or an Affiliate. The Incentive Period shall generally be three (3)
years, unless another expiration date is specified by the Committee or the Plan
provides otherwise.

         (3) Corporate Performance Factors. The amount of compensation payable
to a Participant on account of an ICU award shall be determined by application
of the following factors:

                  (i)      the change in Book Value per share of Stock over the
                           designated Incentive Period;

                  (ii)     the growth in earning per share of Stock over the
                           designated Incentive Period;

                  (iii)    the average return on equity of Stock over the
                           designated Incentive Period; or

                  (iv)     such other factors as the Committee shall specify at
                           the time of grant.

         (d) Valuation of Incentive Compensation Unit. (1) Valuation at
Expiration of Incentive Period. As soon as practicable after the Incentive
Period expires, Pentair's audited financial statements for the preceding Fiscal
Year shall be provided in final form to the Committee, which shall determine the
value of each ICU. Such value shall be based on the net increase in Book Value
over the Incentive Period, calculated by subtracting the beginning Book Value
(determined as of the December 31 immediately preceding the date the ICUs were
awarded) from the ending Book Value (determined on the December 31 immediately
following the end of the Incentive Period). The resulting number shall then be
subject to adjustment by a multiplier which takes into account average return on
equity, compounded growth in earnings per share, or any other corporate
performance factors established with respect to the award being valued.

         (2) Valuation if Incentive Period Shortened. If for any reason an
Incentive Period is shortened, the Committee shall determine the value of an
affected Participant's ICUs as soon as practicable after the date such Period
prematurely ends, and for this purpose, the ending Book Value shall be
determined as of the December 31 immediately preceding the date the Incentive
Period ends, or as otherwise determined by the Committee.

         (3) Adjustments to Valuation Formula. The Committee shall retain the
discretion to modify the factors or formula used to value an ICU award;
provided, however, that any such change shall be defined in the written
agreement executed pursuant to Section 5.2(a) at the time of grant. No such
modification shall in any event cause the value of an ICU award made to any one
Participant to exceed the maximum possible award as defined in Section
5.2(c)(1).

         (e) Payment of ICU Account. Payment of the value of each ICU shall be
made to the Participant, or, if applicable, a designated beneficiary, as soon as
practicable after valuation. Such payment may be made in cash, Stock, Rights to
Restricted Stock, Restricted Stock or any combination thereof, as the Committee
shall determine at the time of grant. If payment is made in Stock, Rights to
Restricted Stock or Restricted Stock, the


                                 Appendix 3 - 6



shares shall be valued at Fair Market Value (as adjusted for any restrictions)
on the date the Incentive Period expires.

SECTION 6. PERFORMANCE SHARES AND PERFORMANCE UNITS

         6.1. Performance Awards. (a) Performance Agreement. Each award of
Performance Shares and Performance Units shall be evidenced by a written
agreement, executed by the Participant and Pentair. Such agreement shall
establish all terms and conditions applicable to the payment of a Performance
Share or Performance Unit as the Committee may determine, including the
achievement of relevant performance objectives. These performance objectives
shall include such financial measures as return on shareholders equity, growth
in earnings per share, return on sales, growth in income, growth in sales and
various techniques which compare actual returns with required returns based on
cost of capital criteria.

         (b) Performance Accounts. At such time as a performance award is made,
Pentair shall establish an account ("Performance Account") for each Participant
and credit the Performance Units and Performance Shares awarded to such account.
Performance Shares shall be credited in the form of Restricted Stock or Rights
to Restricted Stock. The maintenance of Performance Accounts is principally a
bookkeeping function, and does not entitle a Participant to payment of any
awards hereunder.

         (c) Dividends. Dividends or the equivalent paid with respect to
Restricted Stock shall be paid in cash to the Participant as and when declared,
or as other determined by the Committee. The Committee shall determine whether
dividends or the equivalent declared on Stock subject to Rights to Restricted
Stock shall be paid when declared, or as otherwise determined by the Committee.
Dividends, regardless of when paid, shall be subject to all applicable
withholding taxes.

         6.2. Performance Period and Targets. (a) Performance Period. The
Performance Period shall be established by the Committee at the time of the
award. This period may differ for each award granted to any one Participant.

         (b) Performance Targets. At the time a performance award is
established, the Committee shall establish such performance targets as it
determines to be relevant. Successful completion of performance targets within
the designated Performance Period shall be certified by the Committee, using
such measures of performance during the Performance Period as are specified in
the performance agreement.

         6.3. Earning a Performance Award. The Committee shall pay a performance
award to a Participant based on the degree of attainment of the relevant
performance targets during the Performance Period, and in accordance with the
provisions of the performance agreement. The maximum amount of compensation a
Participant may be granted by reason of a performance award in any one calendar
year shall be $100,000, calculated by reference to Fair Market Value of the
award on date of grant.

         6.4. Payment of Performance Awards. (a) Time for Payment. No
performance award shall be payable until after earned in accordance with the
terms and conditions of the performance agreement, unless otherwise provided in
the Plan or in the sole discretion of the Committee. Any Performance Shares,
Performance Units or other amounts credited to a Performance Account shall be
paid to the Participant only when, and to the extent, the Committee so
determines. All such determinations shall be made during the four (4) month
period immediately following the end of the Performance Period as established in
the performance agreement.

         (b) Form of Payment. Payment of Performance Shares or Performance Units
shall be in the form of cash, Stock, Rights to Restricted Stock or Restricted
Stock, or a combination thereof as determined by the Committee at the time of
grant. If payment is made in Stock, Rights to Restricted Stock or Restricted
Stock, the shares shall be valued at Fair Market Value (as adjusted for any
restrictions) on the date the Performance Period expires.

         6.5. Bonus Plans. (a) Executive Bonus Award. On February 14, 1996,
Pentair adopted the Executive Officer Performance Plan ("EOPP"), an annual bonus
plan designed to compensate participating executive officers for performance as
measured against the key financial measurements defined in the EOPP plan. Cash
awards under the EOPP are limited to an amount equal to an EOPP participant's
annual base salary, even though a total bonus award under the EOPP may exceed
that amount. To the extent an annual bonus award exceeds the amount which can be
paid in cash pursuant to the EOPP, the balance shall be considered an


                                 Appendix 3 - 7



award of Performance Shares payable in the form of Restricted Stock under the
Plan. The performance targets applicable to such Performance Shares shall be the
same as the criteria established under the EOPP for purposes of earning the
award. The Performance Shares so granted shall be subject to any vesting
conditions the Committee may impose as of the date the Performance Shares are
issued. The maximum amount of compensation a Participant may be granted by
reason of a Performance Share award under the EOPP in any one calendar year is
equal to the maximum award available to such Participant under the EOPP, reduced
by the amount of such award payable to the Participant in cash.

         (b) Management Incentive Plan. Pentair also maintains an annual bonus
plan (the "MIP") which provides incentive compensation for management employees
other than executive officers. Like the EOPP, cash awards under the MIP are
limited to an amount equal to a MIP participant's annual base salary, even
though a total bonus award under the MIP may exceed that amount. To the extent
such an annual bonus award exceeds the amount which can be paid in cash under
the MIP, the balance shall be considered an award of Performance Shares payable
in the form of Restricted Stock under the Plan. The Performance Shares so
granted shall be subject to any vesting conditions the Committee may impose as
of the date the Performance Shares are issued. The maximum amount of
compensation a Participant may be granted by reason of a Performance Share award
under the MIP in any one calendar year is equal to the maximum award available
to such Participant under the MIP reduced by the amount of such award payable to
the Participant in cash.

SECTION 7. TERMINATION OF EMPLOYMENT

         7.1. General Rule. Except as otherwise provided herein, Options and
SARs may be exercised and Restricted Stock, Rights to Restricted Stock, ICUs,
Performance Share or Performance Unit awards paid to a Participant only in
accordance with the terms and conditions specified by the Committee at the time
of grant.

         7.2. Exceptions for Death, Disability or Retirement. (a) Death of
Participant. If a Participant's employment terminates due to death, any benefits
under the Plan may be transferred to the beneficiary designated by the
Participant. If no beneficiary has been duly designated, said benefits shall
transfer pursuant to the provisions of such Participant's will, or if there is
no will, by the laws of intestate succession in the state in which the
Participant is domiciled on the date of death. The individual who succeeds to
the Participant's benefits under the Plan may:

         (i)      exercise any outstanding Options to the same extent the
                  Participant was entitled to exercise such Options, together
                  with any Options the Committee may accelerate, at any time
                  prior to the earlier of six (6) months from the date of the
                  Participant's death, or the date the Options would otherwise
                  expire by their terms;

         (ii)     receive payment of any shares of Restricted Stock or Rights to
                  Restricted Stock based on a deemed lapse of the restrictions,
                  or of any ICUs based on a deemed expiration of the Incentive
                  Period and attainment of the relevant performance goals,
                  provided that any such payment may be either prorated or
                  otherwise paid as determined by the Committee;

         (iii)    receive payment of a Performance Share or Performance Unit
                  award, as determined by the Committee, based on the degree to
                  which established performance targets had been attained as of
                  the Participant's death.

         (b) Disability of Participant. A Participant who becomes Disabled may:

         (i)      exercise outstanding Options that are otherwise exercisable,
                  together with any Options the Committee may accelerate, at any
                  time prior to the earlier of twelve (12) months after the date
                  of Disability or the date the Options would otherwise expire
                  by their terms;

         (ii)     be paid a prorated amount of an award of Restricted Stock or
                  Rights to Restricted Stock or ICUs, determined by application
                  of the payment provisions in Section 7.2(a)(ii), based on a
                  deemed lapse of restrictions or a deemed expiration of an
                  Incentive Period and attainment of the relevant performance
                  goals;

         (iii)    be paid a Performance Share or Performance Unit award prior to
                  expiration of a Performance Period, as the Committee shall
                  determine by considering the degree of attainment of
                  established performance targets.


                                 Appendix 3 - 8



         (c) Retirement. At the time of Retirement, a Participant may:

         (i)      exercise outstanding Options which are otherwise exercisable,
                  together with any Options the Committee may accelerate, at any
                  time prior to the earlier of thirty (30) days following
                  Retirement, or the date the Options would otherwise expire by
                  their terms;

         (ii)     receive a prorated payment of an award of Restricted Stock,
                  Rights to Restricted Stock or ICUs, determined by application
                  of the payment provisions in Section 7.2(a)(ii), based on a
                  deemed lapse of restrictions or a deemed expiration of an
                  Incentive Period and, if applicable, attainment of relevant
                  performance goals;

         (iii)    receive a payment of Performance Shares or Performance Units
                  as the Committee shall determine by considering the degree to
                  which performance targets have been attained.

         (d) Other Termination of Employment. (1) Termination Not for Cause. If
a Participant's employment ends for reasons other than those listed in Sections
7.2 or 7.3, outstanding Options may be exercised no later than the earlier of
thirty (30) days following such termination, or the date the Options would, by
their terms, expire. Any other outstanding awards under the Plan, to the extent
not then earned and paid to the Participant, shall terminate unless accelerated
by the Committee, subject to the provisions of Section 8.1.

         (2) Termination for Cause. If a Participant's services are terminated
for cause, as determined by the Committee, all Options or other benefits granted
under the Plan, to the extent not already exercised or otherwise earned or paid,
shall terminate.

         7.3. Change in Control. (a) Definitions. Unless the context requires
otherwise, when capitalized the terms listed below shall have the following
meanings when used in this or any other section of the Plan:

                  (1)      "Change in Control" is a change in control of
                           Pentair, as that term is defined in the KEESA.

                  (2)      "KEESA" is the Key Executive Employment and Severance
                           Agreement between Pentair and key executives, as
                           approved by the Board effective August 23, 2000.

         (b) Treatment of Options. Upon the occurrence of a Change in Control,
all Options granted to a Participant who is then employed by Pentair or an
Affiliate shall, to the extent not then vested or exercised, become fully vested
and immediately exercisable without regard to the terms and conditions attached
to such Options at the time of grant. To the extent such Options are then
exercised under circumstances which would otherwise result in a grant of Reload
Options to the Participant, no such Reload Options will be granted.

         (c) Treatment of Restricted Stock. Upon the occurrence of a Change in
Control the restrictions then applicable to all outstanding shares of Restricted
Stock awarded under the Plan shall automatically lapse. If on the Change in
Control date any dividends declared with respect to such Restricted Stock have
not been paid to the Participant, then all such amounts shall be paid within ten
(10) days of the Change in Control date.

         (d) Treatment of Rights to Restricted Stock. Upon the occurrence of a
Change in Control, all Rights to Restricted Stock shall be fully and immediately
vested and the participant shall be paid within ten (10) days the cash value of
the shares of Stock which otherwise would have been issued based on the Fair
Market Value of the Stock on the Change in Control date, together with any then
unpaid dividends which have been declared on the Stock subject to the award of
Rights to Restricted Stock.

         (e) ICUs. Outstanding ICUs shall be valued by assuming the corporate
performance goals for the applicable Incentive Period have been met and shall be
paid in cash within ten (10) days of the Change in Control date, as follows:

         (i)      one-third of the ICUs awarded less than one (1) year prior to
                  the Change in Control date shall be paid;

         (ii)     two-thirds of the ICUs awarded one (1), but less than two (2)
                  years prior to the Change in Control date shall be paid;


                                 Appendix 3 - 9



         (iii)    all of the ICUs awarded two (2) or more years prior to the
                  Change in Control date shall be paid.

         (f) Performance Shares. Upon the occurrence of a Change in Control the
restrictions then applicable to all outstanding Performance Shares shall lapse
and any dividends declared with respect to such shares which have not been paid
shall be paid within ten (10) days of the Change in Control date.

         (g) Performance Units. Outstanding Performance Units shall be valued by
assuming all performance targets for the applicable Performance Period have been
fully met and shall be paid as cash within ten (10) days of the Change in
Control date, as follows:

         (i)      one-third of the Performance Units granted less than one (1)
                  year prior to the Change in Control date shall be paid;

         (ii)     two-thirds of the Performance Units granted one (1) but less
                  than two (2) years prior to the Change in Control date shall
                  be paid;

         (iii)    all of the Performance Units granted two (2) or more years
                  prior to the Change in Control date shall be paid.

         (h) Participants Covered under a KEESA. The provisions of this Section
7.3 shall also apply to a Participant who terminates employment before a Change
in Control if the Participant has entered into a KEESA and is entitled to
benefits thereunder pursuant to Section 2(b) of the KEESA.

         (i) Governing Documents. In the case of any conflict between the
provisions of this Section 7.3 and any other provision of the Plan, this Section
7.3 will control. In the case of any conflict between the terms of this Plan and
the terms and provisions of a Participant's KEESA, the terms of such KEESA shall
control to the extent more beneficial to such Participant, and the obligations
of Pentair under such KEESA shall be in addition to any of its obligations under
the Plan.

SECTION 8. CHANGES TO AWARDS

         8.1. Acceleration of Benefits. The Committee shall have the discretion
to accelerate the exercise date of an Option or SAR or the time at which
restrictions on Stock or Rights thereto lapse, to remove any Stock restrictions
or to accelerate the expiration of an Incentive Period or Performance Period due
to changes in applicable tax or other laws, or such other changes of
circumstances as may arise after the date of an award under the Plan, or to take
any such similar action it may decide, in its absolute discretion, is in the
best interests of Pentair and equitable to a Participant (or such Participant's
heirs or beneficiaries). Notwithstanding the above, however, the Committee shall
have no discretion to increase the amount of compensation a Participant could
earn by application of the preestablished performance goals and financial
measurements relevant to the award, although the Committee shall retain the
discretion to decrease any such award. Any action by the Committee to accelerate
a grant or award for reasons other than death, disability or change in control
of Pentair shall include application of a commercially reasonable discount to
the compensation payable to reflect the value of accelerated payment.

         8.2. Accounting Standards. Calculation of changes to any performance
goal established for purposes of making awards under the Plan shall be without
regard to changes in accounting methods used by Pentair or in accounting
standards that may be required by the Financial Accounting Standards Board after
the goal is established and prior to the time compensation earned on account of
achievement of the relevant performance goal is paid to the Participant.

         8.3. Amendment of Awards. The Committee shall have the discretion to
amend the terms of any grant or award made under the Plan. Any such amendment
may be made either prospectively or retroactively, as necessary, provided that
no such amendment shall either impair the rights of an affected Participant
without the consent of such Participant or amend the terms of an Option so as to
reduce the Option price. Absent shareholder approval, the Committee may not
cancel any outstanding Option and replace it with a new Option which has a lower
Option price, if such action would have the same economic effect as reducing the
Option price of such a canceled Option.


                                Appendix 3 - 10



SECTION 9. MISCELLANEOUS PROVISIONS

         9.1. Stockholder Privileges. (a) Options. Until such time as a Stock
certificate is issued, a Participant, or other person entitled to exercise an
Option under the Plan, shall have none of the privileges of a stockholder with
respect to Stock covered by an Option granted under this Plan.

         (b) Other Awards. Upon delivery of Restricted Stock to a Participant
(or to an escrow holder, if applicable) such Participant shall have all of the
rights of a shareholder with respect to the Restricted Stock, subject to the
restrictions imposed, including the right to receive dividends and vote the
shares of Restricted Stock. Participants for whom an account is established to
record an award of Rights to Restricted Stock shall not have the rights of a
shareholder until such time as the Rights to Restricted Stock vest, but may, in
the discretion of the Committee, receive payment of or credit for the equivalent
of dividends otherwise payable with respect to the number of shares of Stock to
which such Rights to Restricted Stock relate.

         In the event of forfeiture, the certificate or certificates, if any,
representing such Restricted Stock shall be delivered to Pentair, accompanied by
executed instruments of transfer. If the Restricted Stock is held in escrow,
Pentair shall be entitled to have the certificates representing the Restricted
Stock redelivered to it out of escrow.

         (c) Interest. The Committee may provide for the crediting of earnings
interest with respect to Performance Units or ICUs credited to a Participant's
account. Any rate of earnings credited hereunder shall be determined by the
Committee.

         (d) Sale of Stock or Restricted Stock. The Committee may fix a period
during which any Stock, Right to Restricted Stock or Restricted Stock acquired
under the Plan may not be sold, provided that the Committee may not fix any
period which is less than or which exceeds such requirements as may be imposed
by applicable state or federal law.

         9.2. Amendment, Suspension, Modification and Termination of Plan. The
Committee, subject to approval by the Board, may amend or modify the Plan at any
time to conform to changes in applicable laws or in any other respect deemed to
be in the best interests of Pentair. Pursuant to Code section 422, however, no
such amendment shall, without shareholder approval (i) materially increase the
number of shares of Stock as to which ISOs may be granted under the Plan, (ii)
materially modify the requirements as to eligibility to receive Options under
the Plan, (iii) materially increase the benefits accruing to Participants
receiving ISOs under the Plan, (iv) reduce an ISO Option price below Fair Market
Value on the day the Option is granted, (v) permit the award of SARs other than
in tandem with an ISO, (vi) extend the period during which an Option may be
granted or exercised, or (vii) extend the termination date of the provisions of
the Plan which permit the granting of ISOs. No amendment or modification of the
Plan shall adversely affect any Participant under the Plan, or any section
thereof, without such Participant's consent.

         9.3. Administration. The Plan shall be administered by the Committee.
Pursuant to this delegation, the Committee is authorized to (i) interpret and
construe the Plan, (ii) adopt, amend, or rescind rules and regulations relating
to the Plan, and (iii) make all other determinations necessary or advisable for
the administration of the Plan, to the extent not contrary to the express
provisions of the Plan. Any actions, determinations or other interpretations
made by the Committee within the scope of its authority shall be final, binding
and conclusive for all purposes.

         9.4. Indemnification. To the extent permitted by law, members of the
Committee and the Board shall be indemnified and held harmless by Pentair with
respect to any loss, cost, liability or expense that may reasonably be incurred
in connection with any claim, action, suit or proceeding which arises by reason
of any act or omission under the Plan, taken within the scope of the authority
delegated herein.

         9.5. Expenses. The expenses of maintaining and administering this Plan
shall be borne by Pentair.

         9.6. Rights of Participants. Nothing in this Plan shall interfere with
or limit in any way the right of Pentair or an Affiliate to terminate any
individual's employment at any time, with or without notice or cause. This Plan
does not, nor is it intended to, confer upon any employee the right to continue
in the employment of Pentair or an Affiliate.


                                Appendix 3 - 11



         9.7. Transferability. (a) Nontransferability. Except as otherwise
specified in the Plan, Options, SARs, Restricted Stock, Rights to Restricted
Stock, ICUs, Performance Shares and Performance Units granted or awarded under
the Plan shall not be transferrable.

         (b) Designation of Beneficiary(ies). A Participant may designate a
person or persons to receive his or her Plan benefits in the event of death.
Such designation shall be on forms as prescribed by the Committee and may be
modified or revoked only in writing.

         9.8. Governing Law. To the extent not preempted by applicable federal
law, this Plan shall be construed and interpreted in accordance with the
substantive laws of the State of Minnesota.

                                                                      APPENDIX 4

                                  PENTAIR, INC.
                       EXECUTIVE OFFICER PERFORMANCE PLAN,
                             AS AMENDED AND RESTATED

PURPOSE

A primary objective of Pentair, Inc. ("Pentair" or the "Company") is to be a
top-performing company by consistently achieving profit performance that is
higher than the performance of comparable companies. The Company has also
identified growth as a key strategy for the long-term success of the business.
The return on our investments, whether to support internal growth and
improvements or make acquisitions, is also a key determinant of our business
success and the return to our shareholders. The Company expects to compensate
executive officers for their performance against key financial measurements in
accordance with the terms of the EOPP.

ELIGIBILITY AND PARTICIPATION

Key employees in executive positions will be considered for participation.
Participation is determined by the magnitude and scope of the employee's
position and is subject to Pentair Inc. Compensation Committee nomination. An
employee who participates in this program is not eligible for the Pentair
Management Incentive Plan.

QUALIFYING POSITIONS AND BOC PERCENTAGES

Bonus Opportunity Category ("BOC") percentages are assigned to each qualifying
position by the Compensation Committee based on competitive market data. Annual
awards under the EOPP are determined by multiplying the participant's base
salary by his or her Bonus Opportunity Category percentage (a percentage of base
salary based on position) and by the Corporate Performance Factor.

The current designated Qualifying Position and BOC percentage is:

      QUALIFYING POSITION                   BOC PERCENTAGE
      -------------------                   --------------
      Chairman, CEO                                  100%

The BOC percentage for other positions that may qualify for future participation
at the discretion of the Compensation Committee are:

      President, Chief Operating Officer             80.0%
      Executive VP's and Operating Officers          58.5%
      Other Senior Officers                          52.0%

INCENTIVE AWARDS

Incentive Awards under the EOPP are determined according to the following
formula:

           INCENTIVE AWARD = BASE SALARY X BOC% X CPF

                  Base Salary = Actual base salary earned during the year

                  BOC% = Bonus Opportunity Category Percentage

                  CPF = Corporate Performance Factor

         CASH PAY-OUT LIMIT

         The cash incentive award for the fiscal year will be limited to one
         times the participant's annual base salary. The portion in excess of
         one times the participant's annual base salary will be awarded as
         shares of


                                 Appendix 4 - 1



         restricted stock. The restricted stock will be subject to the terms and
         provisions of the Omnibus Stock Incentive Plan.

         MAXIMUM AWARD

         No participant will receive an Incentive Award (cash plus stock)
         greater than $3.5 million or 200% of annual base salary.

         TIMING OF PAY-OUT

         Incentive Awards for a fiscal year shall be paid as soon as
         administratively possible after the annual audit is complete and the
         Compensation Committee has reviewed and approved the payment.

         MINIMUM OPERATING INCOME REQUIREMENT

         If Pentair's operating income (after corporate charges) is zero or
         less, there will be no bonus payouts.

ESTABLISHMENT OF COMPANY GOALS AND FACTORS

EOPP performance goals are a reflection of the overall financial goals for
Pentair and are based on the comparative market data and the historical and
expected performance of the Company. These performance goals are used in
calculating the Corporate Performance Factor. The performance goals that make up
the Corporate Performance Factor are Pentair Value Added ("PVA") and Free Cash
Flow. The use of these two factors reinforces the importance of balancing
economically profitable growth and cash generation. The achievement of these
goals will add to shareholder value and move Pentair toward its top performance
objectives.

Specific EOPP performance targets with respect to these goals are established by
the Compensation Committee of the Board of Directors prior to or early in each
fiscal year. The EOPP targets established for a fiscal year are measured against
Pentair's performance for that fiscal year. The performance goals have been
designed to be used over multiple fiscal years, although the specific targets
will be determined annually by the Compensation Committee.

CORPORATE PERFORMANCE FACTOR

The Corporate Performance Factor is determined by multiplying factors for PVA
and Free Cash Flow. PVA is calculated as a target percentage of Net Operating
Profit After Taxes ("NOPAT") less a surcharge against average invested capital.
Free Cash Flow is equal to net cash provided by operating activities, excluding
net tax-affected interest expense, less capital expenditures. The achievement of
(a) Free Cash Flow equal to the target percentage of NOPAT and (b) PVA generated
that equates to the target percentage total business return, results in a
Corporate Performance Factor of 1.00. The maximum Corporate Performance Factor
is 4.50 and the minimum Corporate Performance Factor is 0.10; however, there is
no bonus if the Company has an operating loss. If the Company's performance
results in a negative PVA, the maximum performance factor is capped at 2.00.

The following grid shows the range of performance factors for each measure that
when multiplied together give the total Corporate Performance Factor.

PERFORMANCE MULTIPLIER GRID

                             PERFORMANCE FACTOR GRID

                                  -------       -------        -------
PVA Factor                          .20          1.00            3.00
Free Cash Flow Factor               .50          1.00            1.50
CPF (PVA x Cash Flow)               .10          1.00            4.50

*Performance falling between stated factors will be interpolated.


                                 Appendix 4 - 2



The Compensation Committee may further refine the calculation of PVA and Free
Cash Flow in future years to measure the targets it sets in each year. The
achievement of the established targets is measured by applying generally
accepted accounting principles used by the Company in preparing its financial
statements.

CONSIDERATION FOR ACQUISITIONS/DIVESTITURES

In the case of acquisitions and divestitures generally, no special adjustment
will be necessary because they flow into the calculations and impact the results
and payouts.

In the event of a significant acquisition or divestiture, however, the Committee
has discretion to use pro forma results or to exclude the effect of a
transaction, if the Committee determines it is necessary to achieve consistency
in measuring year-over-year results or it is otherwise advisable in the
interests of fairness or to achieve the purposes of the Plan.

APPROVAL OF FINAL AWARDS

The Compensation Committee will review and approve all goals and final Incentive
Awards granted under this plan. The Compensation Committee has the flexibility
to reduce or eliminate the award based on its business judgment. The
Compensation Committee does not have the authority or discretion to award more
than the incentive award generated by the formula, subject to the stated limits.

GENERAL PROVISIONS

1.       Nothing contained herein shall be construed to limit or affect in any
         manner or degree the normal and usual powers of management, including
         the right to terminate the employment of any participant or remove
         him/her from participating in the EOPP at any time.

2.       The judgment of the Compensation Committee in administering the EOPP
         will be final, conclusive and binding upon all officers and employees
         of Pentair and its subsidiaries, whether or not selected as
         participants hereunder, and their heirs, executors, personal
         representatives and assigns.

3.       The Compensation Committee has the authority and duties to:

         a.       Determine the rights and benefits under the EOPP of
                  participants and other persons;

         b.       Interpret the terms of the EOPP and apply them to different
                  situations;

         c.       Approve, process and direct the payment of EOPP benefits, and

         d.       Adopt rules, procedures and forms which are appropriate for
                  the smooth and proper operation of the EOPP.

4.       In the event of death, a participant's designated beneficiary will be
         entitled to the participant's Plan benefits. If a participant does not
         designate a beneficiary, the participant's beneficiary(ies) will be
         determined according to the participant's will. If there is no will,
         the beneficiary(ies) shall be determined by the laws of descent and
         distribution of the state in which the participant is a resident on the
         date of death.

5.       A participant does not have the right to assign, transfer, encumber or
         dispose of any award under the Plan until it is distributed to the
         participant. Also, no award is liable to the claims of any creditor of
         the participant until it is distributed to him or her.

6.       The Compensation Committee subject to approval by the Pentair, Inc.
         Board of Directors, has the right to terminate the Plan at any time.

7.       Calculations may exclude or otherwise take into account the impact of
         changes in accounting methods used by Pentair or required by the
         Financial Accounting Standards Board if the Committee determines it is
         necessary to achieve consistency in measuring year-over-year results or
         it is otherwise advisable in the interests of fairness or to achieve
         the purposes of the Plan.


                                 Appendix 4 - 3



CHANGE IN CONTROL

For purposes of the EOPP, a "Change in Control" is a change in control of
Pentair as defined in the KEESA, and the "KEESA" is the Key Executive Employment
and Severance Agreement, as approved by the Pentair Board of Directors effective
August 23, 2000.

If an EOPP participant is employed by Pentair on the date of a Change in
Control, or if an EOPP participant who has entered into a KEESA terminates
employment before a Change in Control but is entitled to benefits under Section
2(b) of the KEESA, then the following provisions shall apply.

1.       If the Change in Control occurs prior to the end of the fiscal year to
         which an Incentive Award relates, the Incentive Award for such fiscal
         year shall be (i) determined by using the participant's annual base
         salary rate as in effect immediately before the Change in Control and
         by assuming the EOPP Goals for such fiscal year have been attained, and
         (ii) paid to the participant in cash within ten (10) days of the Change
         in Control.

2.       If the Change in Control occurs at such time as the participant has not
         received payment of an Incentive Award for a prior fiscal year, then
         the cash portion of such Incentive Award allocated to the participant,
         based upon the attainment of the EOPP Goals for such fiscal year, shall
         be paid to the participant within ten (10) days of the Change in
         Control.

3.       The requirement that the participant remain employed through the end of
         the incentive period to which the Incentive Award relates shall not
         apply.

4.       The requirement that an Incentive Award be paid after completion of an
         annual audit and completion of a review and approval by the
         Compensation Committee shall not apply.

5.       The Minimum Operating Income Requirement provision of the EOPP shall
         not apply to the Incentive Award described in paragraph 1 immediately
         preceding.

6.       The Compensation Committee shall not have the discretion to reduce the
         amount of, or eliminate, an Incentive Award.

7.       The Maximum Award provision of the EOPP shall remain in effect.

8.       If an Incentive Award for a fiscal year referenced in paragraph 2
         immediately preceding exceeds one times the participant's annual base
         salary for such year, then immediately upon a Change in Control such
         excess shall be paid to the participant in restricted shares and such
         shares shall be subject to the terms and provisions of the Pentair
         Omnibus Stock Incentive Plan upon a Change in Control.

9.       To the extent any provision of the EOPP may be in conflict with this
         Change in Control provision, the provisions of this section shall
         apply. In the case of any conflict between the terms and provisions of
         this Plan and the terms and provisions of the KEESA entered into by an
         EOPP participant, the terms of such KEESA shall control to the extent
         more beneficial to such participant, and the obligations of Pentair
         under such KEESA shall be in addition to any of its obligations under
         the EOPP.
