              RIGHTS AGREEMENT


          This Agreement, dated as of July 21, 1995,
between Pentair, Inc., a Minnesota corporation (the
"Company"), and Norwest Bank Minnesota, National
Association (the "Rights Agent").

          WHEREAS, the Board of Directors of the
Company has authorized and declared a dividend of one
common share purchase right (a "Right") for each Common
Share (as hereinafter defined) of the Company
outstanding on July 31, 1995 (the "Record Date") payable
on July 31, 1995 (the "Payment Date"), and has
authorized and directed the issuance of one Right with
respect to each Common Share that shall become
outstanding between the Record Date and the earliest of
the Distribution Date, the Redemption Date and the Final
Expiration Date (as such terms are hereinafter defined),
each Right representing the right to purchase one Common
Share of the Company, subject to adjustment as
hereinafter provided, and upon the terms and subject to
the conditions hereinafter set forth;

          NOW, THEREFORE, in consideration of the
premises and the mutual agreements herein set forth, the
parties hereby agree as follows:

         Section 1.  Certain Definitions.  For
purposes of this Agreement, the following terms have the
meanings indicated:

              (a)  "Acquiring Person" shall mean any
Person (as such term is hereinafter defined) who or
which, together with all Affiliates and Associates (as
such terms are hereinafter defined) of such Person,
shall be the Beneficial Owner (as such term is
hereinafter defined) of 15% or more of the Common Shares
of the Company then outstanding, but shall not include
the Company, any Subsidiary (as such term is hereinafter
defined) of the Company, any employee benefit plan of
the Company or any Subsidiary of the Company, any entity
holding Common Shares for or pursuant to the terms of
any such plan, or any trustee, administrator or
fiduciary of such a plan.  Notwithstanding the
foregoing, no Person shall become an "Acquiring Person"
as the result of an acquisition of Common Shares by the
Company which, by reducing the number of shares
outstanding, increases the proportionate number of
shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding;
provided, however, that if a Person becomes the
Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding by reason of share
purchases by the Company and shall, after such share
purchases by the Company, become the Beneficial Owner of
any additional Common Shares (other than Common Shares
acquired solely as a result of corporate action of the
Company not caused, directly or indirectly, by such
Person) of the Company, then such Person shall be deemed
to be an "Acquiring Person."

              (b)  "Affiliate" and "Associate" shall
have the respective meanings ascribed to such terms in
Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), as in effect on the date of this
Agreement.

              (c)  A Person shall be deemed the
"Beneficial Owner" of and shall be deemed to
"beneficially own" any securities:

                 (i)  which such Person or
    any of such Person's Affiliates or
    Associates beneficially owns, directly or
    indirectly;

                 (ii)  which such Person or
    any of such Person's Affiliates or
    Associates has (A) the right to acquire
    (whether such right is exercisable
    immediately or only after the passage of
    time) pursuant to any agreement,
    arrangement or understanding (other than
    customary agreements with and between
    underwriters and selling group members with
    respect to a bona fide public offering of
    securities), or upon the exercise of
    conversion rights, exchange rights, rights
    (other than these Rights), warrants or
    options, or otherwise; provided, however,
    that a Person shall not be deemed the
    Beneficial Owner of, or to beneficially
    own, securities tendered pursuant to a
    tender or exchange offer made by or on
    behalf of such Person or any of such
    Person's Affiliates or Associates until
    such tendered securities are accepted for
    purchase or exchange; or (B) the right to
    vote pursuant to any agreement, arrangement
    or understanding; provided, however, that a
    Person shall not be deemed the Beneficial
    Owner of, or to beneficially own, any
    security if the agreement, arrangement or
    understanding to vote such security (1)
    arises solely from a revocable proxy or
    consent given to such Person in response to
    a public proxy or consent solicitation made
    pursuant to, and in accordance with, the
    applicable rules and regulations of the
    Exchange Act and (2) is not also then
    reportable on Schedule 13D under the
    Exchange Act (or any comparable or
    successor report); or

                 (iii)  which are
    beneficially owned, directly or indirectly,
    by any other Person with which such Person
    or any of such Person's Affiliates or
    Associates has any agreement, arrangement
    or understanding (other than customary
    agreements with and between underwriters
    and selling group members with respect to a
    bona fide public offering of securities)
    for the purpose of acquiring, holding,
    voting (except to the extent contemplated
    by the proviso to Section 1(c)(ii)(B)) or
    disposing of any securities of the Company.

         Notwithstanding anything in this definition
of Beneficial Ownership to the contrary, the phrase
"then outstanding," when used with reference to a
Person's Beneficial Ownership of securities of the
Company, shall mean the number of such securities then
issued and outstanding together with the number of such
securities not then actually issued and outstanding
which such Person would be deemed to beneficially own
hereunder.

              (d)  "Business Day" shall mean any day
other than a Saturday, a Sunday, or a day on which
banking institutions in the State of Minnesota are
authorized or obligated by law or executive order to
close.

              (e)  "Close of business" on any given
date shall mean 5:00 P.M., St. Paul, Minnesota time, on
such date; provided, however, that if such date is not
a Business Day it shall mean 5:00 P.M., St. Paul,
Minnesota time, on the next succeeding Business Day.

              (f)  "Common Shares" when used with
reference to the Company shall mean the shares of common
stock, par value $.16-2/3 per share of the Company, or
shares having equivalent rights, privileges and
preferences to common stock.  "Common Shares" when used
with reference to any Person other than the Company
shall mean the capital stock (or equivalent equity
interest) with the greatest voting power of such other
Person or, if such other Person is a Subsidiary of
another Person, the Person or Persons which ultimately
control such first-mentioned Person.

              (g)  "Distribution Date" shall have
the meaning set forth in Section 3(a) hereof.

              (h)  "Final Expiration Date" shall
have the meaning set forth in Section 7 hereof.

              (i)  "Person" shall mean any
individual, firm, corporation or other entity, and shall
include any successor (by merger or otherwise) of such
entity.

              (j)  "Redemption Date" shall have the
meaning set forth in Section 7 hereof.

              (k)  "Shares Acquisition Date" shall
mean the first date of public announcement (which, for
purposes of this definition, shall includes, without
limitation, a report filed pursuant to Section 13(d)
under the Exchange Act) by the Company or an Acquiring
Person that an Acquiring Person has become such.

              (l)  "Subsidiary" of any Person shall
mean any corporation or other entity of which a majority
of the voting power of the voting equity securities or
equity interest is owned, directly or indirectly, by
such Person.

         Section 2.  Appointment of Rights Agent. 
The Company hereby appoints the Rights Agent to act as
agent for the Company and the holders of the Rights
(who, in accordance with Section 3 hereof, shall prior
to the Distribution Date also be the holders of Common
Shares) in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such
appointment.  The Company may from time to time appoint
such co-Rights Agents as it may deem necessary or
desirable.

         Section 3.  Issue of Right Certificates.

              (a)  Until the earlier of (i) the
tenth day after the Shares Acquisition Date or (ii) the
tenth Business Day (or such later date as may be
determined by action of the Company's Board of Directors
prior to such time as any Person becomes an Acquiring
Person) after the date of the commencement of, or of the
first public announcement of the intention of any Person
to commence, a tender or exchange offer the consummation
of which would result in any Person (other than the
Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the
Company, any entity holding Common Shares for or
pursuant to the terms of any such plan, or any trustee,
administrator or fiduciary of such a plan) becoming the
Beneficial Owner of Common Shares of the Company
aggregating 15% or more of the then outstanding Common
Shares (including in either case any such date which is
after the date of this Agreement and prior to the
Payment Date; the earlier of such dates being herein
referred to as the "Distribution Date"; provided,
however, that if the tenth day or Business Day, as the
case may be, after the pertinent date occurs before the
Record Date, "Distribution Date" shall mean the Record
Date), (x) the Rights will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates
for Common Shares registered in the names of the holders
thereof (which certificates shall also be deemed to be
Right Certificates) and not by separate Right
Certificates, and (y) the right to receive Right
Certificates will be transferable only in connection
with the transfer of Common Shares.  As soon as
practicable after the Distribution Date, the Company
will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be
sent (and the Rights Agent will, if requested, send) by
first-class, insured, postage-prepaid mail, to each
record holder of Common Shares as of the close of
business on the Distribution Date, at the address of
such holder shown on the records of the Company, a Right
Certificate, in substantially the form of Exhibit A
hereto (a "Right Certificate"), evidencing one Right for
each Common Share so held.  As of the Distribution Date,
the Rights will be evidenced solely by such Right
Certificates.

              (b)  The Company has prepared a
Summary of Rights to Purchase Common Shares, attached as
Exhibit B hereto (the "Summary of Rights"), a copy of
which is available free of charge from the Company. 
With respect to certificates for Common Shares
outstanding as of the Record Date, until the
Distribution Date, the Rights will be evidenced by such
stock certificates registered in the names of the
holders thereof.  Until the Distribution Date (or the
earlier of the Redemption Date or the Final Expiration
Date), the surrender for transfer of any certificate for
Common Shares outstanding on the Record Date, with or
without a copy of the Summary of Rights attached
thereto, shall also constitute the transfer of the
Rights associated with the Common Shares represented
thereby.

              (c)  Certificates for Common Shares
which become outstanding (including, without limitation,
reacquired Common Shares referred to in the last
sentence of this paragraph (c)) after the Record Date
but prior to the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise
affixed to them the following legend (provided, however,
that certificates for Common Shares in existence on the
Record Date may bear the legend required by the
Company's predecessor rights agreement):

         This certificate also evidences and
         entitles the holder hereof to certain
         Rights as set forth in a Rights Agreement
         between Pentair, Inc. and Norwest Bank
         Minnesota, National Association (the
         "Rights Agent"), dated as of July 21, 1995,
         as such agreement may be amended (the
         "Rights Agreement"), the terms of which are
         hereby incorporated herein by reference and
         a copy of which is on file at the principal
         executive offices of Pentair, Inc.  Under
         certain circumstances, as set forth in the
         Rights Agreement, such Rights will be
         evidenced by separate certificates and will
         no longer be evidenced by this certificate. 
         Pentair, Inc. will mail to the holder of
         this certificate a copy of the Rights
         Agreement without charge after receipt of a
         written request therefor.  Under certain
         circumstances set forth in the Rights
         Agreement, Rights issued to, or held by, an
         Acquiring Person or any Affiliate or
         Associate thereof (as such terms are
         defined in the Rights Agreement), whether
         held by such Person or any subsequent
         holder, shall become null and void.

With respect to such certificates containing the
foregoing legend, until the Distribution Date, the
Rights associated with the Common Shares represented by
such certificates shall be evidenced by such
certificates alone, and the surrender for transfer of
any such certificate shall also constitute the transfer
of the Rights associated with the Common Shares
represented thereby.  In the event that the Company
purchases or acquires any Common Shares after the Record
Date but prior to the Distribution Date, any Rights
associated with such Common Shares shall be deemed
cancelled and retired.

         Section 4.  Form of Right Certificates.  The
Right Certificates (and the forms of election to
purchase Common Shares and of assignment to be printed
on the reverse thereof) shall be substantially the same
as Exhibit A hereto and may have such marks of
identification or designation and such legends,
summaries or endorsements printed thereon as the Company
may deem appropriate and as are not inconsistent with
the provisions of this Agreement, or as may be required
to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which the Rights may
from time to time be listed, or to conform to usage. 
Subject to the provisions of Section 22 hereof, the
Right Certificates shall entitle the holders thereof to
purchase such number of Common Shares as shall be set
forth therein at the price per Common Share set forth
therein (the "Purchase Price"), but the amount and type
of securities purchasable upon exercise of each Right
and the Purchase Price shall be subject to adjustment as
provided herein.

         Section 5.  Countersignature and
Registration.

              (a)  The Right Certificates shall be
executed on behalf of the Company by its Chairman of the
Board, Chief Executive Officer, President, Chief
Financial Officer or any Vice President, either manually
or by facsimile signature, shall have affixed thereto
the Company's seal or a facsimile thereof, and shall be
attested by the Secretary or an Assistant Secretary of
the Company, either manually or by facsimile signature. 
The Right Certificates shall be manually countersigned
by the Rights Agent and shall not be valid for any
purpose unless countersigned.  In case any officer of
the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the
Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right
Certificates, nevertheless, may be countersigned by the
Rights Agent and issued and delivered by the Company
with the same force and effect as though the individual
who signed such Right Certificates had not ceased to be
such officer of the Company; and any Right Certificate
may be signed on behalf of the Company by any person
who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to
sign such Right Certificate, although at the date of the
execution of this Rights Agreement any such individual
was not such an officer.

              (b)  Following the Distribution Date,
the Rights Agent will keep or cause to be kept, at its
principal office, books for registration and transfer of
the Right Certificates issued hereunder.  Such books
shall show the names and addresses of the respective
holders of the Right Certificates, the number of Rights
evidenced on its face by each of the Right Certificates
and the date and certificate number of each of the Right
Certificates.

         Section 6.  Transfer, Split Up, Combination
and Exchange of Right Certificates; Mutilated,
Destroyed, Lost or Stolen Right Certificates.

              (a)  Subject to the provisions of
Section 14 hereof, at any time after the close of
business on the Distribution Date, and at or prior to
the close of business on the earlier of the Redemption
Date or the Final Expiration Date, any Right Certificate
or Right Certificates (other than Right Certificates
representing Rights that have become void pursuant to
Section 11(a)(ii) hereof or that have been exchanged
pursuant to Section 24 hereof) may be transferred, split
up, combined or exchanged for another Right Certificate
or Right Certificates, entitling the registered holder
to purchase a like number of Common Shares as the Right
Certificate or Right Certificates surrendered then
entitle such holder to purchase.  Any registered holder
desiring to transfer, split up, combine or exchange any
Right Certificate or Right Certificates shall make such
request in writing delivered to the Rights Agent, and
shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or
exchanged at the principal office of the Rights Agent. 
Thereupon the Rights Agent shall countersign and deliver
to the person entitled thereto a Right Certificate or
Right Certificates, as the case may be, as so requested. 
The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed
in connection with any transfer, split up, combination
or exchange of Right Certificates.

              (b)  Upon receipt by the Company and
the Rights Agent of evidence reasonably satisfactory to
them of the loss, theft, destruction or mutilation of a
Right Certificate and, in case of loss, theft or
destruction, of indemnity or security reasonably
satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all
reasonable expenses incidental thereto, and upon
surrender to the Rights Agent and cancellation of the
Right Certificate if mutilated, the Company will make
and deliver a new Right Certificate of like tenor to the
Rights Agent for delivery to the registered holder in
lieu of the Right Certificate so lost, stolen, destroyed
or mutilated.

         Section 7.  Exercise of Rights; Purchase
Price; Expiration Date of Rights.

              (a)  The registered holder of any
Right Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole
or in part at any time after the Distribution Date upon
surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly
executed, to the Rights Agent at the principal office of
the Rights Agent, together with payment of the Purchase
Price for each Common Share as to which the Rights are
exercised, at or prior to the earliest of (i) the close
of business on July 31, 2005 (the "Final Expiration
Date"), (ii) the time at which the Rights are redeemed
as provided in Section 23 hereof (the "Redemption
Date"), and (iii) the time at which such Rights are
exchanged as provided in Section 24 hereof.

              (b)  The Purchase Price for each
Common Share pursuant to the exercise of Rights shall
initially be $160.00, shall be subject to adjustment
from time to time as provided in Sections 11 and 13
hereof and shall be payable in lawful money of the
United States of America or in Common Shares of the
Company in accordance with paragraph (c) below.

              (c)  Upon receipt of a Right
Certificate representing exercisable Rights, with the
form of election to purchase duly executed, accompanied
by payment of the Purchase Price for the Common Shares
to be purchased as set forth below and an amount equal
to any applicable transfer tax required to be paid by
the holder of such Right Certificate in accordance with
Section 9 hereof, as set forth below, the Rights Agent
shall thereupon promptly (i) requisition from any
transfer agent of the Common Shares certificates for the
number of Common Shares to be purchased and the Company
hereby irrevocably authorizes its transfer agent to
comply with all such requests, (ii) when appropriate,
requisition from the Company the amount of cash to be
paid in lieu of issuance of fractional Common Shares in
accordance with Section 14 hereof, (iii) after receipt
of such certificates, cause the same to be delivered to
or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be
designated by such holder, and (iv) when appropriate,
after receipt, deliver such cash to or upon the order of
the registered holder of such Right Certificate.  The
payment of the Purchase Price (as such amount may be
reduced pursuant to Section 11(a)(iii) hereof) shall be
made in cash or by certified check, cashier's check,
bank draft or money order payable to the order of the
Company, except that, if so provided by the Board of
Directors of the Company, the payment of the Purchase
Price following the occurrence of a Section 11(a)(ii)
Event (as such term is hereinafter defined) and until
the first occurrence of a Section 13 Event (as such term
is hereinafter defined) may be made wholly or in part by
delivery of a certificate or certificates (with
appropriate stock powers executed in blank attached
thereto) evidencing a number of Common Shares of the
Company equal to the then Purchase Price divided by the
closing price (as determined pursuant to Section 11(d)
hereof) per Common Share on the Trading Day (as such
term is hereinafter defined) immediately preceding the
date of such exercise.  If the Company is obligated to
issue other securities of the Company, pay cash and/or
distribute other property pursuant to Section 11(a)
hereof, the Company will make all arrangements necessary
so that such other securities, cash and/or other
property are available for distribution by the Rights
Agent, if and when appropriate.

              (d)  In case the registered holder of
any Right Certificate shall exercise less than all the
Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining
unexercised shall be issued by the Rights Agent to the
registered holder of such Right Certificate or to his
duly authorized assigns, subject to the provisions of
Section 14 hereof.

              (e)  Notwithstanding anything in this
Agreement to the contrary, neither the Rights Agent nor
the Company shall be obligated to take any action with
respect to a registered holder of a Right Certificate
upon the occurrence of any purported transfer,
assignment or exercise as set forth in this Section 7
unless such registered holder shall have (i) completed
and signed the certificate following the form of
assignment or election to purchase set forth on the
reverse of the Right Certificate surrendered for such
transfer, assignment or exercise, and (ii) provided such
additional evidence of the identity of the Beneficial
Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably
request.

         Section 8.  Cancellation and Destruction of
Right Certificates.  All Right Certificates surrendered
for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the
Company or to any of its agents, be delivered to the
Rights Agent for cancellation or in cancelled form, or,
if surrendered to the Rights Agent, shall be cancelled
by it, and no Right Certificates shall be issued in lieu
thereof except as expressly permitted by any of the
provisions of this Rights Agreement.  The Company shall
deliver to the Rights Agent for cancellation and
retirement, and the Rights Agent shall so cancel and
retire, any other Right Certificate purchased or
acquired by the Company otherwise than upon the exercise
thereof.  The Rights Agent shall deliver all cancelled
Right Certificates to the Company or shall, at the
written request of the Company, destroy such cancelled
Right Certificates, and in such case shall deliver a
certificate of destruction thereof to the Company.

         Section 9.  Reservation and Availability of
Common Shares.

              (a)  The Company covenants and agrees
that it will cause to be reserved and kept available out
of its authorized and unissued Common Shares the number
of Common Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance
with Section 7.

              (b)  If the Common Shares issuable
upon the exercise of Rights are then listed on any
national securities exchange, the Company shall use its
best efforts to cause, from and after such time as the
Rights become exercisable, all Common Shares reserved
for such issuance to be listed on such exchange upon
official notice of issuance upon such exercise.

              (c)  The Company covenants and agrees
that it will take all such action as may be necessary to
ensure that all Common Shares delivered upon exercise of
Rights shall, at the time of delivery of the
certificates for such shares (subject to payment of the
Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares (except
as otherwise provided by any corporation law applicable
to the Company).

              (d)  The Company further covenants and
agrees that it will pay when due and payable any and all
federal and state transfer taxes and charges which may
be payable in respect of the issuance or delivery of the
Right Certificates or of any Common Shares upon the
exercise of Rights.  The Company shall not, however, be
required to pay any transfer tax which may be payable in
respect of any transfer or delivery of Right
Certificates to a person other than, or the issuance or
delivery of certificates for the Common Shares in a name
other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise
or to issue or to deliver any certificates for Common
Shares upon the exercise of any Rights until any such
tax shall have been paid (any such tax being payable by
the holder of such Right Certificate at the time of
surrender) or until it has been established to the
Company's reasonable satisfaction that no such tax is
due.

         Section 10.  Common Shares Record Date. 
Each Person in whose name any certificate for Common
Shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of
record of the Common Shares represented thereby on, and
such certificate shall be dated, the date upon which the
Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any
applicable transfer taxes) was made; provided, however,
that if the date of such surrender and payment is a date
upon which the Common Shares transfer books of the
Company are closed, such Person shall be deemed to have
become the record holder of such shares on, and such
certificate shall be dated, the next succeeding Business
Day on which the Common Shares transfer books of the
Company are open.

         Section 11.  Adjustment of Purchase Price,
Number of Shares or Number of Rights.  The Purchase
Price, the number of Common Shares covered by each Right
and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section
11.

              (a)    (A)  In the event the
    Company shall at any time after the date of
    this Agreement (A) declare a dividend on
    the Common Shares payable in Common Shares,
    (B) subdivide the outstanding Common
    Shares, (C) combine the outstanding Common
    Shares into a smaller number of Common
    Shares or (D) issue any shares of its
    capital stock in a reclassification of the
    Common Shares (including any such
    reclassification in connection with a
    consolidation or merger in which the
    Company is the continuing or surviving
    corporation), except as otherwise provided
    in this Section 11(a), the Purchase Price
    in effect at the time of the record date
    for such dividend or of the effective date
    of such subdivision, combination or
    reclassification, and the number and kind
    of shares of capital stock issuable on such
    date, shall be proportionately adjusted so
    that the holder of any Right exercised
    after such time shall be entitled to
    receive the aggregate number and kind of
    shares of capital stock which, if such
    Right had been exercised immediately prior
    to such date and at a time when the Common
    Shares transfer books of the Company were
    open, such holder would have owned upon
    such exercise and been entitled to receive
    by virtue of such dividend, subdivision,
    combination or reclassification; provided,
    however, that in no event shall the
    consideration to be paid upon the exercise
    of one Right be less than the aggregate par
    value of the shares of capital stock of the
    Company issuable upon exercise of one
    Right.  If an event occurs which would
    require an adjustment under both Section
    11(a)(i) and Section 11(a)(ii), the
    adjustment provided for in this Section
    11(a)(i) shall be in addition to, and shall
    be made prior to, any adjustment required
    pursuant to Section 11(a)(ii).

                 (i)  Subject to Section 24
    of this Agreement, in the event any Person
    shall become an Acquiring Person, other
    than pursuant to any transaction set forth
    in Section 13(a), each holder of a Right
    shall thereafter have a right to receive,
    upon exercise thereof at a price equal to
    the then current Purchase Price multiplied
    by the number of Common Shares for which a
    Right is then exercisable, in accordance
    with the terms of this Agreement, such
    number of Common Shares of the Company as
    shall equal the result obtained by (x)
    multiplying the then current Purchase Price
    by the number of Common Shares for which a
    Right is then exercisable and dividing that
    product by (y) 50% of the then current per
    share market price of the Common Shares
    (determined pursuant to Section 11(d)) on
    the date the Person became an Acquiring
    Person (such number of shares, the
    "Adjustment Shares").

              From and after such time as a
    Person becomes an Acquiring Person (a
    "Section 11(a)(ii) Event"), any Rights that
    are or were acquired or beneficially owned
    by such Acquiring Person (or any Associate
    or Affiliate of such Acquiring Person)
    shall be void and any holder of such Rights
    shall thereafter have no right to exercise
    such Rights under any provision of this
    Agreement.  No Right Certificate shall be
    issued pursuant to Section 3 that
    represents Rights beneficially owned by an
    Acquiring Person whose Rights would be void
    pursuant to the preceding sentence or any
    Associate or Affiliate thereof; no Right
    Certificate shall be issued at any time
    upon the transfer of any Rights to an
    Acquiring Person whose Rights would be void
    pursuant to the preceding sentence or any
    Associate or Affiliate thereof or to any
    nominee of such Acquiring Person, Associate
    or Affiliate; and any Right Certificate
    delivered to the Rights Agent for transfer
    to an Acquiring Person whose Rights would
    be void pursuant to the preceding sentence
    shall be cancelled.

                 (ii)  In the event that
    there shall not be sufficient Common Shares
    of the Company authorized but unissued (and
    not reserved for issuance for purposes
    other than upon exercise of the Rights) to
    permit the exercise in full of the Rights
    in accordance with the foregoing
    subparagraph (ii), the Company shall:  (A)
    determine the excess of (1) the value of
    the Adjustment Shares issuable upon the
    exercise of a Right (the "Current Value")
    over (2) the Purchase Price (such excess,
    the "Spread"), and (B) with respect to each
    Right, make adequate provision to
    substitute for the Adjustment Shares, upon
    payment of the applicable Purchase Price,
    (1) cash, (2) a reduction in the Purchase
    Price, (3) Common Shares or other equity
    securities of the Company (including,
    without limitation, shares, or units of
    shares, of preferred stock which the Board
    of Directors of the Company has deemed to
    have the same value as Common Shares (such
    shares of preferred stock, hereinafter
    referred to as ("common stock
    equivalents")), (4) debt securities of the
    Company, (5) other assets or (6) any
    combination of the foregoing, having an
    aggregate value equal to the Current Value,
    where such aggregate value has been
    determined by the Board of Directors of the
    Company based upon the advice of a
    nationally recognized investment banking
    firm selected by the Board of Directors of
    the Company; provided, however, if the
    Company shall not have made adequate
    provision to substitute for the Adjustment
    Shares pursuant to clause (B) above within
    thirty (30) days following the occurrence
    of a Section 11(a)(ii) Event (the "Section
    11(a)(ii) Trigger Date"), then the Company
    shall be obligated to deliver, upon the
    surrender for exercise of a Right and
    without requiring payment of the Purchase
    Price, Common Shares (to the extent
    available) and then, if necessary, cash,
    which shares and/or cash have an aggregate
    value equal to the Spread.  If the Board of
    Directors of the Company shall determine in
    good faith that it is likely that
    sufficient additional Common Shares might
    be authorized for issuance for exercise in
    full of the Rights, the thirty (30) day
    period set forth above may be extended to
    the extent necessary, but not more than
    ninety (90) days after the Section
    11(a)(ii) Trigger Date, in order that the
    Company may seek shareholder approval for
    the authorization of such additional shares
    (such period, as it may be extended, the
    "Substitution Period").  To the extent that
    the Company determines that some action
    need be taken pursuant to the first and/or
    second sentences of this Section
    11(a)(iii), the Company (x) shall provide,
    subject to the last paragraph of Section
    11(a)(ii) hereof, that such action shall
    apply uniformly to all outstanding Rights,
    and (y) may suspend the exercisability of
    the Rights until the expiration of the
    Substitution Period to seek any
    authorization of additional shares and/or
    to decide the appropriate form of
    distribution to be made pursuant to such
    first sentence and to determine the value
    thereof.  In the event of any such
    suspension, the Company shall issue a
    public announcement stating that the
    exercisability of the Rights has been
    temporarily suspended, as well as a public
    announcement at such time as the suspension
    is no longer in effect.  For purposes of
    this Section 11(a)(iii), the value of the
    Common Shares shall be the current per
    share market price (as determined pursuant
    to Section 11(d) hereof) of the Common
    Shares on the Section 11(a)(ii) Trigger
    Date and the value of any "common stock
    equivalent" shall be deemed to have the
    same value as the Common Shares on such
    date.

              (b)  In case the Company shall fix a
record date for the issuance of rights, options or
warrants to all holders of Common Shares entitling them
(for a period expiring within 45 calendar days after
such record date) to subscribe for or purchase Common
Shares (or securities convertible into Common Shares) at
a price per Common Share (or having a conversion price
per share, if a security convertible into Common Shares)
less than the then current per share market price of the
Common Shares (as defined in Section 11(d)) on such
record date, the Purchase Price to be in effect after
such record date shall be determined by multiplying the
Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall
be the number of Common Shares outstanding on such
record date plus the number of Common Shares which the
aggregate offering price of the total number of Common
Shares so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be
offered) would purchase at such current market price and
the denominator of which shall be the number of Common
Shares outstanding on such record date plus the number
of additional Common Shares to be offered for
subscription or purchase (or into which the convertible
securities so to be offered are initially convertible);
provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of
capital stock of the Company issuable upon exercise of
one Right.  In case such subscription price may be paid
in a consideration part or all of which shall be in a
form other than cash, the value of such consideration
shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be
described in a statement filed with the Rights Agent. 
Common Shares owned by or held for the account of the
Company shall not be deemed outstanding for the purpose
of any such computation.  Such adjustment shall be made
successively whenever such a record date is fixed; and
in the event that such rights, options or warrants are
not so issued, the Purchase Price shall be adjusted to
be the Purchase Price which would then be in effect if
such record date had not been fixed.

              (c)  In case the Company shall fix a
record date for the making of a distribution to all
holders of the Common Shares (including any such
distribution made in connection with a consolidation or
merger in which the Company is the continuing or
surviving corporation) of evidences of indebtedness or
assets (other than a regular quarterly cash dividend or
a dividend payable in Common Shares) or subscription
rights or warrants (excluding those referred to in
Section 11(b)), the Purchase Price to be in effect after
such record date shall be determined by multiplying the
Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall
be the then current per share market price of the Common
Shares (as defined in Section 11(d)) on such record
date, less the fair market value (as determined in good
faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed
with the Rights Agent) of the portion of the assets or
evidences of indebtedness so to be distributed or of
such subscription rights or warrants applicable to one
Common Share and the denominator of which shall be such
current per share market price of the Common Shares;
provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of
capital stock of the Company to be issued upon exercise
of one Right.  Such adjustments shall be made
successively whenever such a record date is fixed; and
in the event that such distribution is not so made, the
Purchase Price shall again be adjusted to be the
Purchase Price which would then be in effect if such
record date had not been fixed.

              (d)  For the purpose of any
computation hereunder, the "current per share market
price" of the Common Shares on any date shall be deemed
to be the average of the daily closing prices per Common
Share for the 30 consecutive Trading Days (as such term
is hereinafter defined) immediately prior to such date;
provided, however, that in the event that the current
per share market price of the Common Shares is
determined during a period following the announcement by
the issuer of such Common Shares of (i) a dividend or
distribution on such Common Shares payable in Common
Shares or securities convertible into Common Shares, or
(ii) any subdivision, combination or reclassification of
Common Shares and prior to the expiration of 30 Trading
Days after the ex-dividend date for such dividend or
distribution, or the record date for such subdivision,
combination or reclassification, then, and in each such
case, the current per share market price shall be
appropriately adjusted to reflect the current market
price per Common Share.  The closing price for each
Trading Day shall be the last sale price, regular way,
or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular
way, in either case as reported in the principal
consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New
York Stock Exchange or, if the Common Shares are not
listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated
transaction reporting system with respect to securities
listed on the principal national securities exchange on
which the Common Shares are listed or admitted to
trading or, if the Common Shares are not listed or
admitted to trading on any national securities exchange,
the last quoted price or, if not so quoted, the average
of the high bid and low asked prices in the
over-the-counter market, as reported by the National
Association of Securities Dealers, Inc. Automated
Quotations System ("Nasdaq") or such other system then
in use, or, if on any such date the Common Shares are
not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a
professional market maker making a market in the Common
Shares selected by the Board of Directors of the
Company.  The term "Trading Day" shall mean a day on
which the principal national securities exchange on
which the Common Shares are listed or admitted to
trading or Nasdaq, as the case may be, is open for the
transaction of business or, if the Common Shares are not
listed or admitted to trading on any national securities
exchange or Nasdaq, as the case may be, a Business Day.

              (e)  No adjustment in the Purchase
Price shall be required unless such adjustment would
require an increase or decrease of at least 1% in the
Purchase Price; provided, however, that any adjustments
which by reason of this Section 11(e) are not required
to be made shall be carried forward and taken into
account in any subsequent adjustment.  All calculations
under this Section 11 shall be made to the nearest cent
or to the nearest ten-thousandth of a share as the case
may be.  Notwithstanding the first sentence of this
Section 11(e), any adjustment required by this Section
11 shall be made no later than the earlier of (i) three
years from the date of the transaction which requires
such adjustment or (ii) the date of the expiration of
the right to exercise any Rights.

              (f)  If, as a result of an adjustment
made pursuant to Section 11(a), the holder of any Right
thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than
Common Shares, thereafter the number of such other
shares so receivable upon exercise of any Right shall be
subject to adjustment from time to time in a manner and
on terms as nearly equivalent as practicable to the
provisions with respect to the Common Shares contained
in Section 11(a) through (c), inclusive, and the
provisions of Sections 7, 9, 10 and 13 with respect to
the Common Shares shall apply on like terms to any such
other shares.

              (g)  All Rights originally issued by
the Company subsequent to any adjustment made to the
Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of
Common Shares purchasable from time to time hereunder
upon exercise of the Rights, all subject to further
adjustment as provided herein.

              (h)  Unless the Company shall have
exercised its election as provided in Section 11(i),
upon each adjustment of the Purchase Price as a result
of the calculations made in Section 11(b) and (c), each
Right outstanding immediately prior to the making of
such adjustment shall thereafter evidence the right to
purchase, at the adjusted Purchase Price, that number of
Common Shares (calculated to the nearest ten-thousandth
of a Common Share) obtained by (i) multiplying (x) the
number of Common Shares covered by a Right immediately
prior to this adjustment by (y) the Purchase Price in
effect immediately prior to such adjustment of the
Purchase Price and (ii) dividing the product so obtained
by the Purchase Price in effect immediately after such
adjustment of the Purchase Price.

              (i)  The Company may elect on or after
the date of any adjustment of the Purchase Price to
adjust the number of Rights, in substitution for any
adjustment in the number of Common Shares purchasable
upon the exercise of a Right.  Each of the Rights
outstanding after such adjustment of the number of
Rights shall be exercisable for the number of Common
Shares for which a Right was exercisable immediately
prior to such adjustment.  Each Right held of record
prior to such adjustment of the number of Rights shall
become that number of Rights (calculated to the nearest
one ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the
Purchase Price by the Purchase Price in effect
immediately after adjustment of the Purchase Price.  The
Company shall make a public announcement of its election
to adjust the number of Rights, indicating the record
date for the adjustment, and, if known at the time, the
amount of the adjustment to be made.  This record date
may be the date on which the Purchase Price is adjusted
or any day thereafter, but, if the Right Certificates
have been issued, shall be at least 10 days later than
the date of the public announcement.  If Right
Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be
distributed to holders of record of Right Certificates
on such record date Right Certificates evidencing,
subject to Section 14 hereof, the additional Rights to
which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall
cause to be distributed to such holders of record in
substitution and replacement for the Right Certificates
held by such holders prior to the date of adjustment,
and upon surrender thereof, if required by the Company,
new Right Certificates evidencing all the Rights to
which such holders shall be entitled after such
adjustment.  Right Certificates to be so distributed
shall be issued, executed and countersigned in the
manner provided for herein and shall be registered in
the names of the holders of record of Right Certificates
on the record date specified in the public announcement.

              (j)  Irrespective of any adjustment or
change in the Purchase Price or the number of Common
Shares issuable upon the exercise of the Rights, the
Right Certificates theretofore and thereafter issued may
continue to express the Purchase Price and the number of
Common Shares which were expressed in the initial Right
Certificates issued hereunder.

              (k)  Before taking any action that
would cause an adjustment reducing the Purchase Price
below the par value, if any, of the Common Shares
issuable upon exercise of the Rights, the Company shall
take any corporate action which may, in the opinion of
its counsel, be necessary in order that the Company may
validly and legally issue fully paid and nonassessable
(except as otherwise provided by any corporation law
applicable to the Company) Common Shares at such
adjusted Purchase Price.

              (l)  In any case in which this Section
11 shall require that an adjustment in the Purchase
Price be made effective as of a record date for a
specified event, the Company may elect to defer until
the occurrence of such event the issuing to the holder
of any Right exercised after such record date of the
Common Shares and other capital stock or securities of
the Company, if any, issuable upon such exercise over
and above the Common Shares and other capital stock or
securities of the Company, if any, issuable upon such
exercise on the basis of the Purchase Price in effect
prior to such adjustment; provided, however, that the
Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to
receive such additional shares upon the occurrence of
the event requiring such adjustment.

              (m)  Anything in this Section 11 to
the contrary notwithstanding, the Company shall be
entitled to make such reductions in the Purchase Price,
in addition to those adjustments expressly required by
this Section 11, as and to the extent that it in its
sole discretion shall determine to be advisable in order
that any consolidation or subdivision of the Common
Shares, issuance wholly for cash of any Common Shares at
less than the current market price, issuance wholly for
cash of Common Shares or securities which by their terms
are convertible into or exchangeable for Common Shares,
dividends on Common Shares payable in Common Shares or
issuance of rights, options or warrants referred to
hereinabove in Section 11(b), hereafter made by the
Company to holders of Common Shares shall not be taxable
to such shareholders.

              (n)  The Company covenants and agrees
that it shall not, at any time after the Distribution
Date, (i) consolidate with any other Person (other than
a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), (ii) merge with or
into any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section
11(o) hereof), or (iii) sell or transfer (or permit any
Subsidiary to sell or transfer), in one transaction, or
a series of related transactions, assets or earning
power aggregating more than 50% of the assets or earning
power of the Company and its Subsidiaries (taken as a
whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o)
hereof), if at the time of or immediately after such
consolidation, merger or sale there are any rights,
warrants or other instruments or securities outstanding
or agreements in effect which would substantially
diminish or otherwise eliminate the benefits intended to
be afforded by the Rights.

              (o)  The Company covenants and agrees
that, after the Distribution Date, it will not, except
as permitted by Section 23, Section 24 or Section 27
hereof, take (or permit any Subsidiary to take) any
action if at the time such action is taken it is
reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits
intended to be afforded by the Rights.

         Section 12.  Certificate of Adjusted
Purchase Price or Number of Shares.  Whenever an
adjustment is made as provided in Sections 11 and 13
hereof, the Company shall promptly (a) prepare a
certificate setting forth such adjustment, and a brief
statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer
agent for the Common Shares a copy of such certificate
and (c) mail a brief summary thereof to each holder of
a Right Certificate in accordance with Section 25
hereof.

         Section 13.  Consolidation, Merger or Sale
or Transfer of Assets or Earning Power.

              (a)  In the event that, following the
Shares Acquisition Date, directly or indirectly, (x) the
Company shall consolidate with, or merge with and into,
any other Person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(o)
hereof), and the Company shall not be the continuing or
surviving corporation of such consolidation or merger,
(y) any Person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(o)
hereof) shall consolidate with, or merge with or into,
the Company, and the Company shall be the continuing or
surviving corporation of such consolidation or merger
and, in connection with such consolidation or merger,
all or part of the outstanding Common Shares shall be
changed into or exchanged for stock or other securities
of any other Person (or the Company) or cash or any
other property, or (z) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries
shall sell or otherwise transfer), in one transaction or
a series of related transactions, assets or earning
power aggregating more than 50% of the assets or earning
power of the Company and its Subsidiaries (taken as a
whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more
transactions each of which complies with Section 11(o)
hereof), then, and in each such case, proper provision
shall be made so that:  (i) each holder of a Right
(except as otherwise provided herein) shall thereafter
have the right to receive, upon the exercise thereof at
a price equal to the then current Purchase Price
multiplied by the number of Common Shares for which a
Right is then exercisable (or, if a Section 11(a)(ii)
Event has occurred prior to the first occurrence of any
of the events described in clauses (x), (y) or (z) above
(a "Section 13 Event"), the Purchase Price in effect
immediately prior to the first occurrence of a Section
11(a)(ii) Event multiplied by the number of Common
Shares for which a Right was exercisable immediately
prior to such first occurrence), in accordance with the
terms of this Agreement, such number of validly
authorized and issued, fully paid, nonassessable (except
as otherwise required by any corporation law applicable
to the Principal Party (as such term is hereinafter
defined)) and freely tradeable Common Shares of the
Principal Party, not subject to any liens, encumbrances,
rights of first refusal or other adverse claims, as
shall be equal to the result obtained by (1) multiplying
the then current Purchase Price by the number of Common
Shares for which a Right is exercisable immediately
prior to the first occurrence of a Section 13 Event (or,
if a Section 11(a)(ii) Event has occurred prior to the
first occurrence of a Section 13 Event, multiplying the
number of such shares for which a Right was exercisable
immediately prior to the first occurrence of a Section
11(a)(ii) Event by the Purchase Price in effect
immediately prior to such first occurrence), and
dividing that product (which, following the first
occurrence of a Section 13 Event, shall be referred to
as the "Purchase Price" for each Right and for all
purposes of this Agreement) by (2) 50% of the current
market price (determined pursuant to Section 11(d)
hereof) per Common Share of such Principal Party on the
date of consummation of such Section 13 Event; (ii) such
Principal Party shall thereafter be liable for, and
shall assume, by virtue of such Section 13 Event, all
the obligations and duties of the Company pursuant to
this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party,
it being specifically intended that the provisions of
Section 11 hereof shall apply only to such Principal
Party following the first occurrence of a Section 13
Event; (iv) such Principal Party shall take such steps
(including, but not limited to, the reservation of a
sufficient number of its Common Shares) in connection
with the consummation of any such transaction as may be
necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may
be, in relation to its Common Shares thereafter
deliverable upon the exercise of the Rights; and (v) the
provisions of Section 11(a)(ii) hereof shall be of no
effect following the first occurrence of any Section 13
Event.

              (b)  "Principal Party" shall mean

                 (i)  in the case of any
    transaction described in clause (x) or (y)
    of the first sentence of Section 13(a), the
    Person that is the issuer of any securities
    into which Common Shares are converted in
    such merger or consolidation, and if no
    securities are so issued, the Person that
    is the other party to such merger or
    consolidation; and

                 (ii)  in the case of any
    transaction described in clause (z) of the
    first sentence of Section 13(a), the Person
    that is the party receiving the greatest
    portion of the assets or earning power
    transferred pursuant to such transaction or
    transactions;

provided, however, that in any such case, (1) if the
Common Shares of such Person are not at such time and
have not been continuously over the preceding twelve
(12) month-period registered under Section 12 of the
Exchange Act, and such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which
are and have been so registered, "Principal Party" shall
refer to such other Person; and (2) in case such Person
is a Subsidiary, directly or indirectly, of more than
one Person, the Common Shares of two or more of which
are and have been so registered, "Principal Party" shall
refer to whichever of such Persons is the issuer of the
Common Shares having the greatest aggregate market
value.

              (c)  The Company shall not consummate
any such consolidation, merger, sale or transfer unless
the Principal Party shall have a sufficient number of
authorized Common Shares which have not been issued or
reserved for issuance to permit the exercise in full of
the Rights in accordance with this Section 13 and unless
prior thereto the Company and such Principal Party shall
have executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth
in paragraphs (a) and (b) of this Section 13 and further
providing that, as soon as practicable after the date of
any consolidation, merger or sale of assets mentioned in
paragraph (a) of this Section 13, the Principal Party
will:

                 (i)  prepare and file a
    registration statement under the Securities
    Act of 1933, as amended (the "Act"), with
    respect to the Rights and the securities
    purchasable upon exercise of the Rights on
    an appropriate form, and will use its best
    effort to cause such registration statement
    to (A) become effective as soon as
    practicable after such filing and (B)
    remain effective (with a prospectus at all
    times meeting the requirements of the Act)
    until the Final Expiration Date; and

                 (ii)  deliver to holders of
    the Rights historical financial statements
    for the Principal Party and each of its
    Affiliates which comply in all respects
    with the requirements for registration on
    Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply
to successive mergers or consolidations or sales or
other transfers.  In the event that a Section 13 Event
shall occur at any time after the occurrence of a
Section 11(a)(ii) Event, the Rights which have not
theretofore been exercised shall thereafter become
exercisable in the manner described in Section 13(a).

         Section 14.  Fractional Rights and
Fractional Shares.  (a)  The Company shall not be
required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights.  In
lieu of such fractional Rights, there shall be paid to
the registered holders of the Right Certificates with
regard to which such fractional Rights would otherwise
be issuable, an amount in cash equal to the same
fraction of the current market value of a whole Right. 
For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price
of the Rights for the Trading Day immediately prior to
the date on which such fractional Rights would have been
otherwise issuable.  The closing price for any day shall
be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing
bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction
reporting system with respect to securities listed or
admitted to trading on the principal national securities
exchange on which the Rights are listed or admitted to
trading or, if the Rights are not listed or admitted to
trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the
high bid and low asked prices in the over-the-counter
market, as reported by Nasdaq or such other system then
in use or, if on any such date the Rights are not quoted
by any such organization, the average of the closing bid
and asked prices as furnished by a professional market
maker making a market in the Rights selected by the
Board of Directors of the Company.  If on any such date
no such market maker is making a market in the Rights
the fair value of the Rights on such date as determined
in good faith by the Board of Directors of the Company
shall be used.

              (b)  The Company shall not be required
to issue fractions of Common Shares upon exercise of the
Rights or to distribute certificates which evidence
fractional Common Shares.  In lieu of fractional Common
Shares, the Company shall pay to the registered holders
of Right Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to
the same fraction of the current market value of one
Common Share.  For purposes of this Section 14(b), the
current market value of a Common Share shall be the
closing price of a Common Share (as determined pursuant
to the second sentence of Section 11(d) hereof) for the
Trading Day immediately prior to the date of such
exercise.

              (c)  The holder of a Right by the
acceptance of the Right expressly waives his right to
receive any fractional Rights or any fractional shares
upon exercise of a Right (except as provided above).

         Section 15.  Rights of Action.  All rights
of action in respect of this Agreement, excepting the
rights of action given to the Rights Agent under Section
18 hereof, are vested in the respective registered
holders of the Right Certificates (and, prior to the
Distribution Date, the registered holders of the Common
Shares); and any registered holder of any Right
Certificate (or, prior to the Distribution Date, of the
Common Shares), without the consent of the Rights Agent
or of the holder of any other Right Certificate (or,
prior to the Distribution Date, of the Common Shares),
may, in his own behalf and for his own benefit, enforce,
and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise
act in respect of, his right to exercise the Rights
evidenced by such Right Certificate in the manner
provided in such Right Certificate and in this
Agreement.  Without limiting the foregoing or any
remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach
of this Agreement and will be entitled to specific
performance of the obligations under, and injunctive
relief against actual or threatened violations of the
obligations of any Person subject to, this Agreement.

         Section 16.  Agreement of Right Holders. 
Every holder of a Right, by accepting the same, consents
and agrees with the Company and the Rights Agent and
with every other holder of a Right that:

              (a)  prior to the Distribution Date,
the Rights will be transferable only in connection with
the transfer of the Common Shares;

              (b)  after the Distribution Date, the
Right Certificates are transferable only on the registry
books of the Rights Agent if surrendered at the
principal office of the Rights Agent, duly endorsed or
accompanied by a proper instrument of transfer; and

              (c)  the Company and the Rights Agent
may deem and treat the person in whose name the Right
Certificate (or, prior to the Distribution Date, the
associated Common Shares certificate) is registered as
the absolute owner thereof and of the Rights evidenced
thereby (notwithstanding any notations of ownership or
writing on the Right Certificates or the associated
Common Shares certificate made by anyone other than the
Company or the Rights Agent) for all purposes
whatsoever, and neither the Company nor the Rights Agent
shall be affected by any notice to the contrary.

         Section 17.  Right Certificate Holder Not
Deemed a Shareholder.  No holder, as such, of any Right
Certificate shall be entitled to vote, receive dividends
or other distributions or be deemed for any purpose the
holder of the Common Shares or any other securities of
the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall
anything contained herein or in any Right Certificate be
construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a shareholder
of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders
at any meeting thereof, or to give or withhold consent
to any corporate action, or to receive notice of
meetings or other actions affecting shareholders (except
as provided in Section 25 hereof), or to receive
dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by such Right Certificate
shall have been exercised in accordance with the
provisions hereof.

         Section 18.  Concerning the Rights Agent. 
(a)  The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the
Rights Agent, its reasonable expenses and counsel fees
and other disbursements incurred in the administration
and execution of this Agreement and the exercise and
performance of its duties hereunder.  The Company also
agrees to indemnify the Rights Agent for, and to hold it
harmless against, any loss, liability or expense,
incurred without gross negligence, bad faith or willful
misconduct on the part of the Rights Agent, for anything
done or omitted by the Rights Agent in connection with
the acceptance and administration of this Agreement,
including the costs and expenses of defending against
any claim of liability in the premises.

              (b)  The Rights Agent shall be
protected and shall incur no liability for, or in
respect of any action taken, suffered or omitted by it
in connection with, its administration of this Agreement
in reliance upon any Right Certificate or certificate
for the Common Shares or for other securities of the
Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice,
direction, consent, certificate, statement or other
paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or
acknowledged, by the proper person or persons, or
otherwise upon the advice of counsel as set forth in
Section 20 hereof.

         Section 19.  Merger or Consolidation or
Change of Name of Rights Agent.  (a)  Any corporation
into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be
consolidated, or any corporation resulting from any
merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any
corporation succeeding to the stock transfer or
corporate trust business of the Rights Agent or any
successor Rights Agent, shall be the successor to the
Rights Agent under this Agreement without the execution
or filing of any paper or any further act on the part of
any of the parties hereto, provided that such
corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section
21 hereof.  In case at the time such successor Rights
Agent shall succeed to the agency created by this
Agreement, any of the Right Certificates shall have been
countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of the
predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time
any of the Right Certificates shall not have been
countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name
of the predecessor Rights Agent or in the name of the
successor Rights Agent; and in all such cases such Right
Certificates shall have the full force provided in the
Right Certificates and in this Agreement.

              (b)  In case at any time the name of
the Rights Agent shall be changed and at such time any
of the Right Certificates shall have been countersigned
but not delivered, the Rights Agent may adopt the
countersignature under its prior name and deliver Right
Certificates so countersigned; and in case at that time
any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such
Right Certificates either in its prior name or in its
changed name; and in all such cases such Right
Certificates shall have the full force provided in the
Right Certificates and in this Agreement.

         Section 20.  Duties of Rights Agent.  The
Rights Agent undertakes the duties and obligations
imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders
of Right Certificates, by their acceptance thereof,
shall be bound:

              (a)  The Rights Agent may consult with
legal counsel (who may be legal counsel for the
Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights
Agent as to any action taken or omitted by it in good
faith and in accordance with such opinion.

              (b)  Whenever in the performance of
its duties under this Agreement the Rights Agent shall
deem it necessary or desirable that any fact or matter
be proved or established by the Company prior to taking
or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be
conclusively proved and established by a certificate
signed by the Chairman of the Board, the Chief Executive
Officer, the President, the Chief Financial Officer or
any Vice President and by the Treasurer or any Assistant
Treasurer or the Secretary or any Assistant Secretary of
the Company and delivered to the Rights Agent; and such
certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by
it under the provisions of this Agreement in reliance
upon such certificate.

              (c)  The Rights Agent shall be liable
hereunder to the Company and any other Person only for
its own negligence, bad faith or willful misconduct.

              (d)  The Rights Agent shall not be
liable for or by reason of any of the statements of fact
or recitals contained in this Agreement or in the Right
Certificates (except its countersignature thereof) or be
required to verify the same, but all such statements and
recitals are and shall be deemed to have been made by
the Company only.

              (e)  The Rights Agent shall not be
under any responsibility in respect of the validity of
this Agreement or the execution and delivery hereof
(except the due authorization, execution and delivery
hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except
its countersignature thereof); nor shall it be
responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in
any Right Certificate; nor shall it be responsible for
any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section
11(a)(ii) hereof) or any adjustment in the terms of the
Rights (including the manner, method or amount thereof)
provided for in Sections 3, 11, 13, 23 or 24, or the
ascertaining of the existence of facts that would
require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right
Certificates after actual notice that such change or
adjustment is required); nor shall it by any act
hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any
Common Shares or other securities to be issued pursuant
to this Agreement or any Right Certificate or as to
whether any Common Shares or other securities will, when
issued, be validly authorized and issued, fully paid and
nonassessable.

              (f)  The Company agrees that it will
perform, execute, acknowledge and deliver or cause to be
performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as
may reasonably be by required by the Rights Agent for
the carrying out or performing by the Rights Agent of
the provisions of this Agreement.

              (g)  The Rights Agent is hereby
authorized and directed to accept instructions with
respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief
Executive Officer, the President, the Chief Financial
Officer, any Vice President, the Secretary, any
Assistant Secretary, the Treasurer or any Assistant
Treasurer of the Company, and to apply to such officers
for advice or instructions in connection with its
duties, and it shall not be liable for any action taken
or suffered by it in good faith in accordance with
instructions of any such officer or for any delay in
acting while waiting for those instructions.

              (h)  The Rights Agent and any
shareholder, director, officer or employee of the Rights
Agent may buy, sell or deal in, or act as the transfer
agent for, any of the Rights, Common Shares or other
securities of the Company or become pecuniarily
interested in any transaction in which the Company may
be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though
it were not Rights Agent under this Agreement.  Nothing
herein shall preclude the Rights Agent from acting in
any other capacity for the Company or for any other
legal entity.

              (i)  The Rights Agent may execute and
exercise any of the rights or powers hereby vested in it
or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent
shall not be answerable or accountable for any act,
default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company resulting from any
such act, default, neglect or misconduct, provided
reasonable care was exercised in the selection and
continued employment thereof.

         Section 21.  Change of Rights Agent.  The
Rights Agent or any successor Rights Agent may resign
and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company
and to each transfer agent of the Common Shares by
registered or certified mail, and to the holders of the
Right Certificates by first-class mail.  The Company may
remove the Rights Agent or any successor Rights Agent
upon 30 days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and
to each transfer agent of the Common Shares by
registered or certified mail, and to the holders of the
Right Certificates by first-class mail.  If the Rights
Agent shall resign or be removed or shall otherwise
become incapable of acting, the Company shall appoint a
successor to the Rights Agent.  If the Company shall
fail to make such appointment within a period of 30 days
after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the
holder of a Right Certificate (who shall, with such
notice, submit his Right Certificate for inspection by
the Company), then the registered holder of any Right
Certificate may apply to any court of competent
jurisdiction for the appointment of a new Rights Agent. 
Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be (a) a corporation
organized and doing business under the laws of the
United States or of the State of Minnesota or the State
of New York (or of any other state of the United States
so long as such corporation is authorized to do business
as a banking institution in the State of Minnesota or
the State of New York), in good standing, having an
office in the State of Minnesota or the State of New
York, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject
to supervision or examination by federal or state
authority and which has at the time of its appointment
as Rights Agent a combined capital and surplus of at
least $50 million, or (b) an Affiliate of a corporation
described in clause (a) of this sentence.  After
appointment, the successor Rights Agent shall be vested
with the same powers, rights, duties and
responsibilities as if it had been originally named as
Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to
the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further
assurance, conveyance, act or deed necessary for the
purpose.  Not later than the effective date of any such
appointment the Company shall file notice thereof in
writing with the predecessor Rights Agent and each
transfer agent of the Common Shares, and mail a notice
thereof in writing to the registered holders of the
Right Certificates.  Failure to give any notice provided
for in this Section 21, however, or any defect therein,
shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the
appointment of the successor Rights Agent, as the case
may be.

         Section 22.  Issuance of New Right
Certificates.  Notwithstanding any of the provisions of
this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by its
Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under
the Right Certificates made in accordance with the
provisions of this Agreement.

         Section 23.  Redemption.  (a)  The Rights
may be redeemed by action of the Board of Directors
pursuant to subsection (b) of this Section 23 and shall
not be redeemed in any other manner.

         (b)  The Board of Directors of the Company
may, at its option, at any time prior to the earlier of
(i) the close of business on the tenth day following the
Shares Acquisition Date (or, if the Shares Acquisition
Date shall have occurred prior to the Record Date, the
close of business on the tenth day following the Record
Date), or (ii) the Final Expiration Date, redeem all but
not less than all of the then outstanding Rights at a
redemption price of $.01 per Right, appropriately
adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof
(such redemption price being hereinafter referred to as
the "Redemption Price").  The redemption of the Rights
by the Board of Directors may be made effective at such
time, on such basis and with such conditions as the
Board of Directors in its sole discretion may establish. 
Notwithstanding anything contained in this Agreement to
the contrary, the Rights shall not be exercisable after
the first occurrence of a Section 11(a)(ii) Event until
such time as the Company's right of redemption hereunder
has expired.

         (c)  Immediately upon the effectiveness of
the action of the Board of Directors of the Company
ordering the redemption of the Rights pursuant to
subsection (b) of this Section 23 and without any
further action and without any notice, the right to
exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive
the Redemption Price.  The Company shall promptly give
public notice of any such redemption; provided, however,
that the failure to give, or any defect in, any such
notice shall not affect the validity of such redemption. 
Within 10 days after the effectiveness of the action of
the Board of Directors ordering the redemption of the
Rights pursuant to subsection (b), the Company shall
mail a notice of redemption to all the holders of the
then outstanding Rights at their last addresses as they
appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of
the transfer agent for the Common Shares.  Any notice
which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the
notice.  Each such notice of redemption will state the
method by which the payment of the Redemption Price will
be made.  Neither the Company nor any of its Affiliates
or Associates may redeem, acquire or purchase for value
any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section
24 or Section 30 hereof, and other than in connection
with the purchase of Common Shares prior to the
Distribution Date.

         Section 24.  Exchange.  (a)  The Board of
Directors of the Company may, at its option, at any time
after any Person becomes an Acquiring Person, exchange
all or part of the then outstanding and exercisable
Rights (which shall not include Rights that have become
void pursuant to the provisions of Section 11(a)(ii)
hereof) for Common Shares of the Company at an exchange
ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof
(such exchange ratio being hereinafter referred to as
the "Exchange Ratio").  Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect
such exchange at any time after any Person (other than
the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, any
entity holding Common Shares for or pursuant to the
terms of any such plan, or any trustee, administrator or
fiduciary of such a plan), together with all Affiliates
and Associates of such Person, becomes the Beneficial
Owner of 50% or more of the Common Shares then
outstanding.

              (b)  Immediately upon the action of
the Board of Directors of the Company ordering the
exchange of any Rights pursuant to subsection (a) of
this Section 24 and without any further action and
without any notice, the right to exercise such Rights
shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of
Common Shares equal to the number of such Rights held by
such holder multiplied by the Exchange Ratio.  The
Company shall promptly give public notice of any such
exchange; provided, however, that the failure to give,
or any defect in, such notice shall not affect the
validity of such exchange.  The Company promptly shall
mail a notice of any such exchange to all of the holders
of such Rights at their last addresses as they appear
upon the registry books of the Rights Agent.  Any notice
which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the
notice.  Each such notice of exchange will state the
method by which the exchange of the Common Shares for
Rights will be effected and, in the event of any partial
exchange, the number of Rights which will be exchanged. 
Any partial exchange shall be effected pro rata based on
the number of Rights (other than Rights which have
become void pursuant to the provisions of Section
11(a)(ii) hereof) held by each holder of Rights.

              (c)  In any exchange pursuant to this
Section 24, the Company, at its option, may substitute
common stock equivalents (as such term is defined in
Section 11(a)(iii) hereof) for some or all of the Common
Shares exchangeable for Rights.

              (d)  In the event that there shall not
be sufficient Common Shares or common stock equivalents
authorized but unissued to permit any exchange of Rights
as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary
to authorize additional Common Shares or common stock
equivalents for issuance upon exchange of the Rights.

              (e)  The Company shall not be required
to issue fractions of Common Shares or to distribute
certificates which evidence fractional Common Shares. 
In lieu of such fractional Common Shares, the Company
shall pay to the registered holders of the Right
Certificates with regard to which such fractional Common
Shares would otherwise be issued an amount in cash equal
to the same fraction of the current market value of a
whole Common Share.  For the purposes of this paragraph
(e), the current market value of a whole Common Share
shall be the closing price of a Common Share (as
determined pursuant to the second sentence of Section
11(d) hereof) for the Trading Day immediately prior to
the date of exchange pursuant to this Section 24.

         Section 25.  Notice of Certain Events.   (a) 
In case the Company shall propose, after the
Distribution Date, (i) to pay any dividend payable in
stock of any class to the holders of Common Shares or to
make any other distribution to the holders of Common
Shares (other than a regular quarterly cash dividend),
(ii) to offer to the holders of Common Shares rights or
warrants to subscribe for or to purchase any additional
Common Shares or shares of stock of any class or any
other securities, rights or options, (iii) to effect any
reclassification of Common Shares (other than a
reclassification involving only the subdivision of
outstanding Common Shares), (iv) to effect any
consolidation or merger into or with (other than a
merger of a Subsidiary into or with the Company), or to
effect any sale or other transfer (or to permit one or
more of its Subsidiaries to effect any sale or other
transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to, any other Person, or
(v) to effect the liquidation, dissolution or winding up
of the Company, then, in each such case, the Company
shall give to each holder of a Right Certificate, in
accordance with Section 26 hereof, a notice of such
proposed action, which shall specify the record date for
the purposes of such stock dividend, or distribution of
rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, transfer,
liquidation, dissolution, or winding up is to take place
and the date of participation therein by the holders of
the Common Shares if any such date is to be fixed, and
such notice shall be so given in the case of any action
covered by clause (i) or (ii) above at least 10 days
prior to the record date for determining holders of
Common Shares for purposes of such action, and in the
case of any such other action, at least 10 days prior to
the date of the taking of such proposed action or the
date of participation therein by the holders of the
Common Shares, whichever shall be the earlier.

              (b)  In case any Section 11(a)(ii)
Event or Section 13 Event shall occur, then the Company
shall as soon as practicable thereafter give to each
holder of a Right Certificate, in accordance with
Section 26 hereof, a notice of the occurrence of such
event, which notice shall include a brief summary of the
Section 11(a)(ii) Event or Section 13 Event, as the case
may be, and the consequences thereof to holders of
Rights.

         Section 26.  Notices.  (a)  Notices or
demands authorized by this Agreement to be given or made
by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently

              Attention:  _____________________

              (c)  Notices or demands authorized by
this Agreement to be given or made by the Company or the
Rights Agent to the holder of any Right Certificate
shall be sufficiently given or made if sent by first-class mail,
postage prepaid, addressed to such holder at the address
of such holder as shown on the registry books of the Company.

         Section 27.  Supplements and Amendments. 
Prior to the Distribution Date and subject to the
penultimate sentence of this Section 27, the Company may
and the Rights Agent shall, if the Company so directs,
supplement or amend any provision of this Agreement
without the approval of any holders of certificates
representing Common Shares.  Without limiting the
foregoing, the Company may at any time prior to such
time as any Person becomes an Acquiring Person amend
this Agreement to lower the thresholds set forth in
Sections 1(a) and 3(a) hereof from 15% to not less than
10%, with appropriate exceptions for Persons then
beneficially owning Common Shares of the Company
constituting a percentage of the number of Common Shares
then outstanding equal to or in excess of the new
threshold.  From and after the Distribution Date and
subject to the penultimate sentence of this Section 27,
the Company and the Rights Agent shall, if the Company
so directs, supplement or amend this Agreement without
the approval of any holders of Right Certificates in
order (i) to cure any ambiguity, (ii) to correct or
supplement any provision contained herein which may be
defective or inconsistent with any other provision
herein, (iii) to shorten or lengthen any time period
hereunder, or (iv) to change or supplement the
provisions hereunder in any manner which the Company may
deem necessary or desirable and which shall not
adversely affect the interests of the holders of Right
Certificates (other than an Acquiring Person or an
Affiliate or Associate of an Acquiring Person);
provided, that from and after the Distribution Date this
Agreement may not be supplemented or amended to
lengthen, pursuant to clause (iii) of this sentence, (A)
a time period relating to when the Rights may be
redeemed at such time as the Rights are not then
redeemable, or (B) any other time period unless such
lengthening is for the purpose of protecting, enhancing
or clarifying the rights of, and/or the benefits to, the
holders of Rights.  Upon the delivery of a certificate
from an appropriate officer of the Company which states
that the proposed supplement or amendment is in
compliance with the terms of this Section 27, the Rights
Agent shall execute such supplement or amendment. 
Notwithstanding anything contained in this Agreement to
the contrary, no supplement or amendment shall be made
which changes the Redemption Price, the Purchase Price
or the Final Expiration Date.  Prior to the Distribution
Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of
Common Shares.

         Section 28.  Successors.  All the covenants
and provisions of this Agreement by or for the benefit
of the Company or the Rights Agent shall bind and inure
to the benefit of their respective successors and
assigns hereunder.

         Section 29.  Benefits of this Agreement. 
Nothing in this Agreement shall be construed to give to
any person or corporation other than the Company, the
Rights Agent and the registered holders of the Right
Certificates (and, prior to the Distribution Date, the
Common Shares) any legal or equitable right, remedy or
claim under this Agreement; but this Agreement shall be
for the sole and exclusive benefit of the Company, the
Rights Agent and the registered holders of the Right
Certificates (and, prior to the Distribution Date, the
Common Shares).

         Section 30.  Severability.  If any term,
provision, covenant or restriction of this Agreement is
held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full
force and effect and shall in no way be affected,
impaired or invalidated; provided, however, that
notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or
restriction is held by such court or authority to be
invalid, void or unenforceable and the Board of
Directors determines in its good faith judgment that
severing the invalid language from this Agreement would
adversely affect the purpose or effect of this
Agreement, the right of redemption set forth in Section
23 hereof shall be reinstated and shall not expire until
the close of business on the tenth day following the
date of such determination by the Board of Directors.

         Section 31.  Governing Law.  This Agreement
and each Right Certificate issued hereunder shall be
deemed to be a contract made under the laws of the State
of Minnesota and for all purposes shall be governed by
and construed in accordance with the laws of such State
applicable to contracts to be made and performed
entirely within such State and shall be subject to the
exclusive jurisdiction of the courts of, and United
States Federal Courts sitting in, such State.

         Section 32.  Counterparts.  This Agreement
may be executed in any number of counterparts and each
of such counterparts shall for all purposes be deemed to
be an original, and all such counterparts shall together
constitute but one and the same instrument.

         Section 33.  Descriptive Headings. 
Descriptive headings of the several Sections of this
Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any
of the provisions hereof.

         IN WITNESS WHEREOF, the parties hereto have
caused this Agreement to be duly executed and attested,
all as of the day and year first above written.

              PENTAIR, INC.

      SUMMARY OF RIGHTS TO PURCHASE
              COMMON SHARES


          On July 21, 1995, the Board of
Directors of Pentair, Inc. (the "Company")
declared a dividend of one common share purchase
right (a "Right") for each outstanding share of
common stock, par value $.16-2/3 per share (the
"Common Shares"), of the Company.  The dividend
is effective July 31, 1995 for shareholders of
record on such date (the "Record Date").  Each
Right entitles the registered holder to purchase
from the Company one Common Share at a price of
$160.00 per Common Share, subject to adjustment
(the "Purchase Price").  The description and
terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the
Company and Norwest Bank Minnesota, National
Association, as Rights Agent (the "Rights
Agent").

          Until the earlier to occur of (i) 10
days following a public announcement that a
person or group of affiliated or associated
persons (other than the Company, a subsidiary of
the Company or an employee benefit plan of the
Company or a subsidiary) (an "Acquiring Person")
has acquired beneficial ownership of 15% or more
of the outstanding Common Shares (the "Shares
Acquisition Date") or (ii) 10 business days (or
such later date as may be determined by action of
the Company's Board of Directors prior to such
time as any person becomes an Acquiring Person)
following the commencement of, or announcement of
an intention to make, a tender offer or exchange
offer the consummation of which would result in
the beneficial ownership by a person or group
(other than the Company, a subsidiary of the
Company or an employee benefit plan of the
Company or a subsidiary) of 15% or more of such
outstanding Common Shares (the earlier of such
dates being called the "Distribution Date"), the
Rights will be evidenced, with respect to any of
the Common Share certificates outstanding as of
the Record Date, by such Common Share
certificate.

          The Rights Agreement provides that,
until the Distribution Date, the Rights will be
transferred with and only with the Common Shares. 
Until the Distribution Date (or earlier
redemption or expiration of the Rights), new
Common Share certificates issued after the Record
Date, upon transfer or new issuance of Common
Shares, will contain a notation incorporating the
Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for
transfer of any certificates for Common Shares,
outstanding as of the Record Date, even without
such notation, will also constitute the transfer
of the Rights associated with the Common Shares
represented by such certificate.  As soon as
practicable following the Distribution Date,
separate certificates evidencing the Rights
("Right Certificates") will be mailed to holders
of record of the Common Shares as of the close of
business on the Distribution Date and such
separate Right Certificates alone will evidence
the Rights.

          The Rights are not exercisable until
the Distribution Date.  The Rights will expire on
July 31, 2005 (the "Final Expiration Date"),
unless the Rights are earlier redeemed or
exchanged by the Company, in each case, as
described below.

          The Purchase Price payable, and the
number of Common Shares or other securities or
property issuable, upon exercise of the Rights
are subject to adjustment from time to time to
prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or
reclassification of, the Common Shares, (ii) upon
the grant to holders of the Common Shares of
certain rights or warrants to subscribe for or
purchase Common Shares at a price, or securities
convertible into Common Shares with a conversion
price, less than the then current market price of
the Common Shares or (iii) upon the distribution
to holders of the Common Shares of evidences of
indebtedness or assets (excluding regular
quarterly cash dividends or dividends payable in
Common Shares) or of subscription rights or
warrants (other than those referred to above).

          With certain exceptions, no
adjustment in the Purchase Price will be required
until cumulative adjustments require an
adjustment of at least 1% in such Purchase Price. 
No fractional shares will be issued.  In lieu
thereof, an adjustment in cash will be made based
on the market price of the Common Shares on the
last trading day prior to the date of exercise.

          The Purchase Price is payable by
certified check, cashier's check, bank draft or
money order or, if so provided by the Company,
the Purchase Price following the occurrence of a
Flip-In Event (as defined below) and until the
first occurrence of a Flip-Over Event (as defined
below) may be paid in Common Shares having an
equivalent value.

          In the event that any person becomes
an Acquiring Person (a "Flip-In Event"), the
holders of Rights will thereafter have the right
to receive upon exercise that number of Common
Shares (or, in certain circumstances cash,
property or other securities of the Company or a
reduction in the Purchase Price) having a market
value of two times the then current Purchase
Price.  Notwithstanding any of the foregoing,
following the occurrence of a Flip-In Event all
Rights will be null and void to the extent they
are, or (under certain circumstances specified in
the Rights Agreement) were, or subsequently
become beneficially owned by an Acquiring Person,
related persons and transferees.

          In the event that, at any time
following the Shares Acquisition Date, (i) the
Company is acquired in a merger or other business
combination transaction or (ii) 50% or more of
its consolidated assets or earning power are sold
(the events described in clauses (i) and (ii) are
herein referred to as "Flip-Over Events"), proper
provision will be made so that the holders of
Rights will thereafter have the right to receive,
upon the exercise thereof at the then current
Purchase Price, that number of shares of common
stock of the acquiring company which at the time
of such transaction will have a market value of
two times the then current Purchase Price.

          At any time after a person becomes an
Acquiring Person and prior to the acquisition by
such Acquiring Person of 50% or more of the
outstanding Common Shares, the Board of Directors
of the Company may exchange the Rights (other
than Rights owned by such Acquiring Person which
have become void), in whole or in part, at an
exchange ratio of one Common Share (or of a share
of a class or series of the Company's preferred
stock having equivalent rights, preferences and
privileges) per Right (subject to adjustment).

          At any time prior to the close of
business on the tenth day following the Shares
Acquisition Date, the Board of Directors of the
Company may redeem the Rights in whole, but not
in part, at a price of $.01 per Right (the
"Redemption Price").  The redemption of the
Rights may be made effective at such time, on
such basis and with such conditions as the Board
of Directors in its sole discretion may
establish.  Immediately upon any redemption of
the Rights, the right to exercise the Rights will
terminate and the only right of the holders of
Rights will be to receive the Redemption Price.

          Other than the Redemption Price, the
Purchase Price and the Final Expiration Date, the
terms of the Rights may be amended by the Board
of Directors of the Company without the consent
of the holders of the Rights, including an
amendment to lower the threshold for
exercisability of the Rights from 15% to 10%,
with appropriate exceptions for any person then
beneficially owning a percentage of the number of
Common Shares then outstanding equal to or in
excess of the new threshold, except that from and
after the Distribution Date no such amendment may
adversely affect the interests of the holders of
the Rights.

          Until a Right is exercised, the
holder thereof, as such, will have no rights as a
shareholder of the Company, including, without
limitation, the right to vote or to receive
dividends.

          A copy of the Rights Agreement has
been filed with the Securities and Exchange
Commission as an Exhibit to a Registration
Statement on Form 8-A filed with respect to the
Rights.  A copy of the Rights Agreement is
available free of charge from the Company.  This
summary description of the Rights does not
purport to be complete and is qualified in its
entirety by reference to the Rights Agreement,
which is hereby incorporated herein by reference.
