                         AMENDMENT TO THE PENTAIR, INC.
                    NON-QUALIFIED DEFERRED COMPENSATION PLAN

         The Pentair, Inc. Non-Qualified Deferred Compensation Plan, as in
effect for employee compensation deferrals made for periods of employment before
1996 (the "Plan"), is hereby amended effective August 23, 2000 as follows:

         1.       Section 9 is deleted in its entirety and the following
                  substituted therefor:

         9.       Distribution in the Event of Change in Control.

                  A.       Definitions.

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

                           (2)      "KEESA" is the Key Executive Employment and
                                    Severance Agreement between Pentair, Inc.
                                    and key executives, as approved by Pentair's
                                    board of directors effective August 23,
                                    2000.

                  B.       Effect on Participants. Upon a Change in Control, and
                           notwithstanding the benefit election previously made
                           by such participant and other Plan provisions to the
                           contrary, a participant shall receive all of his or
                           her Plan benefits in a cash lump sum on the lump sum
                           date unless such participant timely elects otherwise
                           in accordance with subsection C immediately
                           following. The lump sum date shall be the first
                           business day of the third calendar month following
                           the calendar month in which such Change in Control
                           occurs; provided, however, if the participant is
                           employed by the Company or one of its subsidiaries on
                           the date of the Change in Control, then the lump sum
                           date shall be the first business day of the third
                           calendar month following the calendar month in which
                           such participant terminates employment with the
                           Company and its subsidiaries.

                  C.       Election to Forego Lump Sum. A participant otherwise
                           entitled to receive a lump sum pursuant to subsection
                           B immediately preceding may elect to forego payment
                           of the lump sum if he or she so elects in writing and
                           files such writing with the Administrator no later
                           than thirty (30) days before the lump sum date. If a
                           participant timely elects to forego the lump sum
                           payment, such participant's Plan benefits shall be
                           paid in accordance with the participant's otherwise
                           effective benefit election and Plan provisions apart
                           from this Section 9.

                  D.       No Delay in Payment. Application of this Section 9
                           shall not delay the date for payment of benefits as
                           otherwise elected by a participant

                           or as otherwise provided under the Plan apart from
                           this Section 9.

                  E.       Notice of Lump Sum Entitlement and Election to Forego
                           Lump Sum. No later than five (5) days following the
                           date of the Change in Control, the Administrator
                           shall cause a notice to be sent to all Plan
                           participants to whom the provisions of this Section 9
                           may apply. Such notice shall be sent in a manner
                           reasonably calculated to be actually and timely
                           received by such participants, and shall reasonably
                           inform such participant of the provisions of this
                           Section 9 and such participant's rights and
                           entitlements hereunder. In the event such notice is
                           not timely sent as to a participant, then at such
                           participant's election the lump sum date and the date
                           for electing to forego such lump sum shall be
                           appropriately adjusted to reflect the time periods
                           that would have applied had such notice been timely
                           sent.

         2.       The foregoing amendment shall apply to all participants under
the Plan as of August 23, 2000.

                         AMENDMENT TO THE PENTAIR, INC.
                    NON-QUALIFIED DEFERRED COMPENSATION PLAN

         The Pentair, Inc. Non-Qualified Deferred Compensation Plan, as in
effect for employee compensation deferrals and employer contributions for
periods of employment after 1995 (also known as the "Sidekick"), is hereby
amended effective August 23, 2000 as follows:

         1.       Section 10.2 is deleted in its entirety and the following
                  substituted therefor:

                  SECTION 10.2 CHANGE IN CONTROL.

                           (a) Definitions.

                               (1)  "CHANGE IN CONTROL" is a change in control
                                    of the Company as defined in the KEESA.

                               (2)  "KEESA" is the Key Executive Employment and
                                    Severance Agreement between the Company and
                                    key executives, as approved by the Company's
                                    board of directors effective August 23,
                                    2000.

                           (b) Effect on Participants. If a Participate
         terminates employment, whether voluntarily or involuntarily (other than
         by reason of death), with the Employer within three (3) years following
         a Change in Control, then notwithstanding the benefit election
         previously made by such Participant and other Plan provisions to the
         contrary, such Participant shall receive all of his or her Plan
         benefits in a cash lump sum on the lump sum date unless such
         Participant timely elects otherwise in accordance with subsection (c)
         immediately following. The lump sum date shall be the first business
         day of the third calendar month following the calendar month in which
         such Participant so terminates Employment.

                           The provisions of this Section 10.2 shall also apply
         to a Participant who so 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; provided,
         however, in such circumstances the lump sum date shall be determined as
         if the Participant had so terminated employment on the day following
         the date of the Change in Control.

                           (c) Election to Forego Lump Sum. A Participant
         otherwise entitled to receive a lump sum pursuant to subsection (b)
         immediately preceding may elect to forego payment of the lump sum if he
         or she so elects in writing and files such writing with the Committee
         no later than thirty (30) days before the lump sum date. If a
         Participant timely elects to forego the lump sum payment, such
         Participant's Plan benefits shall be paid in accordance with the
         Participant's otherwise effective benefit election and Plan provisions
         apart from this Section 10.2.

                           (d) No Delay in Payment. Application of this Section
         10.2 shall not delay the date for payment of benefits as otherwise
         elected by a Participant or as

<PAGE>   2

         otherwise provided under the Plan apart from this Section 10.2.

                           (e) Notice of Lump Sum Entitlement and Election to
         Forego Lump Sum. No later than five (5) days following the date of the
         Change in Control, the Committee shall cause a notice to be sent to all
         Participants to whom the provisions of this Section 10.2 may apply.
         Such notice shall be sent in a manner reasonably calculated to be
         actually and timely received by such Participants, and shall reasonably
         inform such Participant of the provisions of this Section 10.2 and such
         Participant's rights and entitlements hereunder. In the event such
         notice is not timely sent as to a Participant, then at such
         Participant's election the lump sum date and the date for electing to
         forego such lump sum shall be appropriately adjusted to reflect the
         time periods that would have applied had such notice been timely sent.

         2. The foregoing amendment shall apply to all participants and their
beneficiaries under the Sidekick as of August 23, 2000 and regardless of whether
such participants actively participated in the Sidekick after 1998.

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

         The undersigned, by the authority of the Board of Directors of Pentair,
Inc., does hereby approve the form and content of this amendment to the
Sidekick. The Vice President of Human Resources shall cause an executed copy of
this amendment to be provided to Fidelity Management Trust Company and
appropriate amendments shall be made to the trust agreement related to Sidekick
to reflect this amendment.
