 RIGHTS AGREEMENT

  
 THIS AGREEMENT, dated as of December 10, 2004,
between Pentair, Inc., a Wisconsin corporation (the “Company”), and Wells Fargo Bank, N.A. (the “Rights Agent”). 
  
 WHEREAS, the Board of Directors of the Company has authorized and declared a dividend of one preferred share purchase right (a “Right”)
for each Common Share (as hereinafter defined) of the Company outstanding upon the close of business on January 28, 2005 (the “Record Date”) payable upon the close of business on such date (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 one-hundredth of a Preferred Share (as hereinafter defined) of the Company 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: 
  
 Item
2. 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 a 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 would, but for the foregoing, become an Acquiring Person 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 of the Company at any time that the Person is or thereby becomes the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding (other than Common Shares acquired solely as a result of corporate action of the Company not caused, directly or indirectly, by such Person), then such Person shall be deemed to be an “Acquiring Person”.
Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a Person who would otherwise be an “Acquiring Person”, as defined pursuant to the foregoing provisions of this paragraph (a), has become
such inadvertently, and such Person divests as promptly as practicable a sufficient number of Common Shares so that such Person would no longer be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this paragraph
(a), then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement. 
  
 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, or with
respect to, 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.,
Minneapolis, Minnesota time, on such date; provided, however, that if such date is not a Business Day it shall mean 5:00 P.M., Minneapolis, 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 $0.16 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 that ultimately control such first-mentioned Person.

  

 2 








 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. “Preferred Shares” shall mean shares of Series A Junior Participating Preferred Stock, par value $0.10 per share, of the Company having the
preferences and rights set forth in Exhibit A attached to this Agreement. 
  
 k. “Redemption Date” shall have the meaning set forth in Section 7 hereof. 
  
 l. “Shares Acquisition Date” shall mean the first date of public announcement (which, for purposes of this definition, shall include, without
limitation, a report filed or amended pursuant to Section 13(d) under the Exchange Act) by the Company or an Acquiring Person that an Acquiring Person has become such. 
  
 m. “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. 
  
 Item 3. 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 the Common Shares of the Company) 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. 
  
 Item 4. 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 Record 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 of the Company 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 of the Company. 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 

  

 3 








 
of Common Shares of the Company 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 B hereto (a “Right Certificate”), evidencing one Right for each Common Share of the Company 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 Preferred Shares, attached as Exhibit C hereto (the “Summary of Rights”), a copy of which is available free of charge from the Company. With respect to certificates for Common Shares of the Company outstanding as of the Record
Date, until the Distribution Date, the Rights will be evidenced by such 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 of the Company 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 of the
Company that become outstanding (including, without limitation, certificates for reacquired Common Shares referred to in the last sentence of this paragraph (c) and certificates issued on the transfer of Common Shares) 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 a legend in substantially the following form (provided, however, that
certificates for Common Shares of the Company 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 Wells Fargo Bank, N.A., dated as of December 10, 2004, and 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 so that the Company shall not be entitled to exercise any Rights
associated with the Common Shares which are no longer outstanding. 
  
 Item 5.
Form of Right Certificates. The Right Certificates (and the forms of election to purchase Preferred Shares and of assignment to be printed on the reverse thereof) shall be substantially the same as Exhibit B 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 

  

 4 








 
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 one one-hundredths of a Preferred Share as shall be set forth therein at the price per one one-hundredth of a Preferred 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. 
  
 Item 6. 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 Treasurer, an Assistant Treasurer, 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 of each of the Right Certificates. 
  
 Item 7. 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 one one-hundredths of a Preferred Share as the Right Certificate or Right Certificates surrendered then entitled 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 

  

 5 








 
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. 
  
 Item 8. 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 one one-hundredth of a Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the close of business on January 28, 2015 (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 one one-hundredth of a Preferred Share pursuant to the exercise of a Right shall initially be $240, 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 shares to be purchased 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) (A) requisition from any transfer agent of the Preferred Shares certificates for the number of Preferred Shares to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B)
requisition from the depositary agent depositary receipts representing such number of one one-hundredths of a Preferred Share as are to be purchased (in which case certificates for the Preferred Shares represented by such receipts shall be deposited
by the transfer agent with the depositary agent), (ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuance of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such
certificates or depositary receipts, 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 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
hereinafter defined) and until the first occurrence of a Section 13 Event (as 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. 
  

 6 








 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. 
  
 Item 9. 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 destroy such cancelled Right
Certificates. 
  
 Item 10. Reservation and Availability of Preferred
Shares. 
  
 a. The Company covenants and agrees that it
will cause to be reserved and kept available out of its authorized and unissued Preferred Shares the number of Preferred Shares that will be sufficient to permit the exercise in full of all outstanding Rights in accordance with Section 7.

  
 b. So long as the Preferred Shares issuable upon the exercise
of Rights may be 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 Preferred 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 Preferred 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 Preferred 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 Preferred 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 Preferred Shares upon the exercise of any Rights until any such tax shall have been paid (any such tax being payable by the holder of 

  

 7 








 
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.

  
 Item 11. Preferred Shares Record Date. Each Person
in whose name any certificate for Preferred Shares is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Preferred 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 Preferred 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 Preferred Shares
transfer books of the Company are open. 
  
 Item 12. Adjustment of
Purchase Price, Number of Shares or Number of Rights. The Purchase Price, the number of Preferred 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. (i) In the event the Company
shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine the outstanding Preferred Shares into a smaller number of
Preferred Shares or (D) issue any shares of its capital stock in a reclassification of the Preferred 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 Preferred 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). 
  
 (ii) 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 one one-hundredths of a Preferred Share for which a Right is then exercisable, in accordance with the terms of this Agreement and in lieu of Preferred Shares, 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 one one-hundredths of a Preferred Share 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 of the Company (determined pursuant to 

  

 8 








 
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. The Company shall use all reasonable efforts to ensure that the provisions of this paragraph are complied with, but shall have no liability to any holder of Right Certificates or other Person as a result of its failure to make any
determinations with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder. 
  
 (iii) In the event that there shall not be sufficient Common Shares of the Company issued but not outstanding or 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) equity securities of the Company (including, without limitation, one one-hundredth of a Preferred Share or 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 of the Company (such one one-hundredth of a Preferred Share or 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 any portion of the Purchase Price, Common Shares of the Company (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 of the Company 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 

  

 9 








 
(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 of the Company shall be the current per share market price (as determined pursuant to Section 11(d) hereof) of the Common Shares of the Company 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 of the Company 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 Preferred Shares entitling them (for a
period expiring within 45 calendar days after such record date) to subscribe for or purchase Preferred Shares (or shares having the same rights, privileges and preferences as the Preferred Shares (“equivalent preferred shares”)) or
securities convertible into Preferred Shares at a price per Preferred Share or equivalent preferred share (or having a conversion price per share, if a security convertible into Preferred Shares or equivalent preferred shares) less than the then
current per share market price of the Preferred 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 Preferred Shares outstanding on such record date plus the number of Preferred Shares which the aggregate offering price of the total number of Preferred Shares and/or
equivalent preferred 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 Preferred
Shares outstanding on such record date plus the number of additional Preferred Shares and/or equivalent preferred 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. Preferred 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 Preferred 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 Preferred 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 

  

 10 








 
price of the Preferred 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
Preferred Share and the denominator of which shall be such current per share market price of the Preferred 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. (i) For the purpose of any computation hereunder, the “current per share market price” of any security (a “Security” for the
purpose of this Section 11(d)(i)) on any date shall be deemed to be the average of the daily closing prices per share of such Security 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 Security is determined during a period following the announcement by the issuer of such Security of (i) a dividend or distribution on such Security payable in
shares of such Security or securities convertible into such shares, or (ii) any subdivision, combination or reclassification of such Security 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 share equivalent of such
Security. 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 Securities 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 Security is listed or admitted to trading or, if the Security is 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 Security is 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 Security 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 Security is listed or admitted to trading is open for the transaction
of business or, if the Security is not listed or admitted to trading on any national securities exchange, a Business Day. 
  
 (ii) For the purpose of any computation hereunder, the “current per share market price” of the Preferred Shares shall be
determined in accordance with the method set forth in Section 11(d)(i). If the Preferred Shares are not publicly traded, the “current per share market price” of the Preferred Shares shall be conclusively deemed to be the current per share
market price of the Common Shares of the Company as determined pursuant to Section 11(d)(i) (appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the Record Date), multiplied by 100. If neither the
Common Shares of the Company nor the Preferred Shares are publicly held or so listed or traded, “current per share market price” shall mean the fair value per share 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. 
  

 11 








 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 one-hundredth 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 Preferred 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 Preferred Shares contained in Section 11(a) through (c), inclusive, and the provisions of Sections 7, 9, 10 and 13 with respect to the Preferred 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 Preferred 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 Preferred Shares (calculated to the nearest one-hundredth of a Preferred Share) obtained by (i) multiplying (x) the number of
one one-hundredth of a Preferred Share 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 one one-hundredths of a Preferred Share
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 one one-hundredths of a Preferred Share 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 one-hundredth) 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, 

  

 12 








 
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 so to be 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 one one-hundredths of a Preferred Share 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 one
one-hundredths of a Preferred Share 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 Preferred 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) Preferred 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 one one-hundredths of a Preferred Share and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of one
one-hundredths of a Preferred Share 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 Preferred Shares, issuance wholly for cash of any Preferred Shares at less than the current market price, issuance wholly for cash of Preferred Shares or securities which by their terms are convertible into or
exchangeable for Preferred Shares, dividends on Preferred Shares payable in Preferred Shares or issuance of rights, options or warrants referred to in Section 11(b) hereof, hereafter made by the Company to holders of its Common Shares shall not be
taxable to such shareholders. 
  
 n. The Company covenants and
agrees that it shall not, at any time after the earlier of the Distribution Date or the Shares Acquisition 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), (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) or (iv) consummate a share exchange with any other Person, if at the time of or immediately after such consolidation, merger, sale or share exchange (A) 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, (B) prior to, simultaneously with or
immediately after such consolidation, merger, sale or share exchange the shareholders of the Person who 

  

 13 








 
constitute, or would constitute, the “Principal Party” for purposes of Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates or (C) the form or nature of organization of the Principal Party would preclude or limit the exercisability of 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. 
  
 p. Anything in this Agreement to the
contrary notwithstanding, in the event that the Company shall at any time after the date hereof and prior to the Distribution Date (i) declare a dividend on the outstanding Common Shares payable in Common Shares, (ii) subdivide the outstanding
Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, the number of Rights associated with each Common Share then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be
proportionately adjusted so that the number of Rights thereafter associated with each Common Share following any such event shall equal the result obtained by multiplying the number of Rights associated with each Common Share immediately prior to
such event by a fraction the numerator which shall be the total number of Common Shares outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of Common Shares outstanding immediately
following the occurrence of such event. 
  
 Item 13. 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 of the Company 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. 
  
 Item 14. Consolidation, Merger, Share
Exchange 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, or any Person or Persons (other than a Subsidiary of the Company in a transaction that complies
with Section 11(o) hereof) shall consummate a share exchange with the Company, and, in connection with such consolidation, merger or share exchange, all or part of the outstanding Common Shares of the Company 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 

  

 14 








 
the exercise thereof at a price equal to the then current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share 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 one one-hundredths of a Preferred Share 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 one one-hundredths of a Preferred Share 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 of the Company are converted in such merger, consolidation or share exchange,
and if no securities are so issued, (A) the Person that is the other party to the merger, consolidation or share exchange and that survives such merger or consolidation, or, if there is more than one such Person, the Person the Common Shares of
which have the greatest aggregate market value of shares outstanding or (B) if the Person that is the other party to the merger or consolidation does not survive the merger or consolidation, the Person that does survive the merger or consolidation
(including the Company if it survives); 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 

  

 15 








 
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, share exchange, 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, share exchange 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 efforts 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, consolidations, share exchanges, 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). 
  
 Item 15. 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 New York Stock Exchange or, if the Rights 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 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. 
  

 16 








 b. The Company shall not be required to issue fractions of Preferred Shares (other than fractions which
are integral multiples of one one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares (other than fractions which are integral multiples of one one-hundredth of a
Preferred Share). Fractions of Preferred Shares in integral multiples of one one-hundredth of a Preferred Share may, at the election of the Company, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Company and a
depositary selected by it; provided, that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares that are not integral multiples of one one-hundredth of a Preferred Share, 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 Preferred Share. For purposes of this Section 14(b), the current market value of a Preferred Share shall be the closing price of a
Preferred Share (as determined pursuant to the second sentence of Section 11(d)(i) 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). 
  
 Item 16. 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. 
  
 Item 17. 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; 
  
 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; and

  

 17 








 (d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent
shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a
court or competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining
performance of such obligation; provided, however, the Company must use its best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible. 
  
 Item 18. 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 Preferred 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. 
  
 Item 19. 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 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 Preferred Shares or 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. 
  
 Item 20. 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 

  

 18 








 
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. 
  
 Item 21. 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 Section 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 

  

 19 








 
make any representation or warranty as to the authorization or reservation of any Preferred Shares or other securities to be issued pursuant to this
Agreement or any Right Certificate or as to whether any Preferred 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 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. 
  
 Item 22. 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 or agency 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 

  

 20 








 
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. 
  
 Item 23. 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. 
  
 Item 24. 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 such time as any Person becomes an Acquiring Person, redeem all but not
less than all the then outstanding Rights at a redemption price of $.001 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 hereof, and other than in connection with the purchase of Common
Shares prior to the Distribution Date. 
  

 21 








 Item 25. 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 of
the Company 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 of the Company 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 of the Company 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 Preferred Shares (or equivalent preferred shares, as such term
is defined in Section 11(b) hereof) for some or all of the Common Shares of the Company exchangeable for Rights, at the initial rate of one one-hundredth of a Preferred Share (or equivalent preferred share) for each Common Share of the Company, as
appropriately adjusted to reflect adjustments in the voting rights of the Preferred Shares pursuant to the terms thereof, so that the fraction of a Preferred Share delivered in lieu of each Common Share of the Company shall have the same voting
rights as one Common Share of the Company. 
  
 d. In the event
that there shall not be sufficient Common Shares of the Company or Preferred Shares issued but not outstanding or 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 of the Company or Preferred Shares for issuance upon exchange of the Rights. 
  
 e. The Company shall not be required to issue fractions of Common Shares of the Company or to distribute certificates which evidence fractional Common
Shares of the Company. In lieu of such fractional Common Shares of the Company, the Company shall pay to the registered holders of the Right Certificates with regard to which such fractional Common Shares of the Company would otherwise be issued an
amount in cash equal to the same fraction of the current market value of a whole Common 

  

 22 








 
Share of the Company. For the purposes of this paragraph (e), the current market value of a whole Common Share of the Company shall be the closing price of a
Common Share of the Company (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. 
  
 Item 26. 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 Preferred Shares or to make any other distribution to the holders of Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer to the holders of Preferred Shares
rights or warrants to subscribe for or to purchase any additional Preferred Shares or shares of stock of any class or any other securities, rights or options, (iii) to effect any reclassification of Preferred Shares (other than a reclassification
involving only the subdivision of outstanding Preferred Shares), (iv) to effect any consolidation or merger into or with (other than a merger of a Subsidiary into or with the Company), to effect any share exchange with 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, share exchange, sale, transfer, liquidation, dissolution, or winding up is to
take place and the date of participation therein by the holders of the Preferred 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 Preferred 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 Preferred Shares, whichever shall be the earlier. 
  
 b. In case any of Section 11(a)(ii) Event or Section 13 Event shall occur, then, in any such case, (i) 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, and (ii) all references in the preceding
paragraph to Preferred Shares shall be deemed thereafter to refer to Common Shares and/or, if appropriate, other securities.

 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

 Item
28. Supplements and Amendments. Prior to such time as any Person becomes an Acquiring Person 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 of the Company. 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 such time as any Person becomes an Acquiring Person 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 such time as any Person becomes an Acquiring
Person 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 that 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 of
the Company. 
  
 Item 29. 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. 
  

 24 








 Item 30. 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 of the Company) 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 of the Company). 
  
 Item 31. 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. 
  
 Item 32.
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. 
  
 Item 33. 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. 
  
 Item 34. 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. 
  
 Item 35. Determinations and Actions by the Board of Directors. For all purposes of this Agreement, any
calculation of the number of Common Shares of the Company outstanding at any particular time, including for purposes of determining the particular percentage of such outstanding Common Shares of which any Person is the Beneficial Owner, shall be
made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act. The Board of Directors of the Company shall have the exclusive power and authority to administer this Agreement and to
exercise all rights and powers specifically granted to the Board of Directors or to the Company, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power to (a) interpret the
provisions of this Agreement, and (b) make all determinations deemed necessary or advisable for the administration of this Agreement (including a determination to redeem or not redeem the Rights or to amend the Agreement and any determination as to
whether actions or any Person shall be such as to cause such Person to beneficially own shares held by another Person). All such actions, calculations, interpretations and determinations (including, for purposes of clause (ii) below, all omissions
with respect to the foregoing) which are done or made by the Board of Directors of the Company in good faith, shall (i) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties, and (ii) not
subject the Board of Directors of the Company to any liability to the holders of the Rights.

 EXHIBIT A 
  

Terms of the Series A Junior Participating Preferred Stock, 
 $0.10 par value, of 
 Pentair, Inc. 
  
 Series A Junior Participating Preferred Stock 
  
 1. Designation and Amount. There is hereby created a series of Preferred Shares that shall be designated as
“Series A Junior Participating Preferred Stock”, par value $0.10 per share (the “Series A Preferred Stock”), and the number of shares constituting such series shall be 2,500,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided that no decrease shall reduce the number of shares of Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance
upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Corporation into Series A Preferred Stock. 
  
 2. Dividends and Distributions. 
  
 (A) The holders of shares of Series A Preferred Stock, in preference to the holders of shares of Common Stock and of any
other junior stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on (i) such day after the end of each calendar quarter as the
Board of Directors determines for the payment of cash dividends on the Common Stock or (ii) if the Board of Directors does not declare a cash dividend on the Common Stock for the quarter, the first business days of January, April, July and October
with respect to the preceding calendar quarter in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (i) $1.00 or (ii) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount
of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all noncash dividends or other distributions, other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock
(by reclassification or otherwise), declared on the Common Stock since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Payment Date, since the first 

  

 A-1 








 
issuance of any share or fraction of a share of Series A Preferred Stock. In the event the Corporation shall at any time after the close of business on
December 10, 2004 (the “Rights Declaration Date”) (a) declare any dividend on Common Stock payable in shares of Common Stock, (b) subdivide the outstanding Common Stock, or (c) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under clause (ii) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock that are outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
  
 (B) The Corporation shall declare a dividend or distribution on the Series A
Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution
shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A Preferred Stock shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date. 
  
 (C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Preferred Stock, unless the date of
issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends
shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Preferred 

  

 A-2 








 
Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. 
  
 3. Voting Rights. The holders of shares of Series A Preferred Stock shall have the following voting rights: 
  
 (A) Each share of Series A Preferred Stock shall entitle the holder thereof
to one vote on all matters submitted to a vote of the shareholders of the Corporation. 
  
 (B) Except as otherwise provided herein, in any other resolution of the Board of Directors creating a series of Preferred Stock or any similar stock, or by law, the holders of shares of Series A Preferred Stock shall
vote as a separate class on all matters submitted to a vote of shareholders of the Corporation. 
  
 4. Certain Restrictions. 
  
 (A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Corporation shall not: 
  
 (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or
otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock; 
  
 (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to
which the holders of all such shares are then entitled; 
  
 (iii) redeem or
purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, provided that the Corporation may at any time
redeem, purchase or otherwise acquire shares of any such 

  

 A-3 








 
parity stock in exchange for shares of any stock of the Corporation ranking junior to or on a parity with (both as to dividends or upon dissolution,
liquidation or winding up) the Series A Preferred Stock; or 
  
 (iv) purchase or
otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by
the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall
determine in good faith will result in fair and equitable treatment among the respective series or classes. 
  
 (B) The Corporation shall not permit any corporation of which an amount of voting securities sufficient to elect at least a majority of the directors of
such corporation is beneficially owned, directly or indirectly, by the Corporation or otherwise controlled by the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could,
under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. 
  
 5. Reacquired Shares. All shares of Series A Preferred Stock that shall at any time have been reacquired by the Corporation shall, after such
reacquisition, have the status of authorized but unissued shares of Preferred Stock of the Corporation, without designation as to series, and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of
the Board of Directors, subject to the conditions and restrictions on issuance set forth herein. 
  
 6. Liquidation, Dissolution or Winding Up. Upon any liquidation, dissolution or winding up of the Corporation, no distribution shall be made (A) to
the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received $100
per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, provided that the holders of shares of Series A Preferred Stock shall be entitled to receive an
aggregate amount per share, subject to the provision for adjustment hereinafter set forth, equal to 100 times the aggregate amount to be distributed per share to holders of shares of Common Stock, or (B) to the holders of shares of stock ranking on
a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except distributions made ratably on the Series A Preferred Stock and all other such parity stock in proportion to the total amounts
to which the holders of all such shares are entitled upon such liquidation, dissolution or winding up. In the event the Corporation shall at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares
of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares
of Common Stock, then in each such case the aggregate amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under the proviso in clause (A) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately
prior to such event. 
  

 A-4 








 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger,
combination, share exchange or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Preferred Stock shall at
the same time be similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as
the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (A) declare any dividend on Common Stock payable in shares of Common Stock,
(B) subdivide the outstanding Common Stock, or (C) combine the outstanding shares of Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares
of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock that are outstanding immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event. 
  
 8. No Redemption. Except as provided in Section 302A.671, Subdivision 6 of the Minnesota Business Corporation Act, the shares of Series A Preferred Stock shall not be mandatorily redeemable. 
  
 9. Amendment. To the fullest extent permitted by applicable law, prior
to such time as shares of Series A Preferred Stock are issued and outstanding, the Board of Directors may modify, amend, alter or revoke any of the number of shares of Series A Preferred Stock, the powers, preferences or special rights of the Series
A Preferred Stock or the other terms of the Series A Preferred Stock. From and after such time as shares of Series A Preferred Stock are issued and outstanding, the Restated Articles of Incorporation of the Corporation shall not be amended in any
manner that would materially alter or change the powers, preferences or special rights of the Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of at least two-thirds of the outstanding shares of
Series A Preferred Stock, voting together as a single class. 
  
 10. Fractional Shares. Series A Preferred Stock may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in
distributions and to have the benefit of all other rights of holders of Series A Preferred Stock.

 EXHIBIT C 
  

PENTAIR, INC. 
  
 SUMMARY OF RIGHTS TO PURCHASE 
 PREFERRED SHARES 
  
 On December 10, 2004, the Board of Directors of Pentair, Inc. (the
“Company”) declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock, par value $.16 2/3 per share (“Common Shares”), of the Company. The dividend is payable upon
the close of business on January 28, 2005 to the shareholders of record upon the close of business on January 28, 2005 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share
of Series A Junior Participating Preferred Stock, $0.10 par value (“Preferred Shares”), of the Company, at a price of $240 per one one-hundredth of a Preferred 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 Wells Fargo Bank, N.A., 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 January 28, 2015 (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 Preferred 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 Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights or warrants to 

  

 C-1 








 
subscribe for or purchase Preferred Shares at a price, or securities convertible into Preferred Shares with a conversion price, less than the then current
market price of the Preferred Shares or (iii) upon the distribution to holders of the Preferred Shares of evidences of indebtedness or assets (excluding regular quarterly cash dividends or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above). 
  
 The
number of outstanding Rights and the number of one one-hundredths of a Preferred Share issuable upon exercise of each Right are also subject to adjustment in the event of a stock split of the Common Shares or a stock dividend on the Common Shares
payable in Common Shares or subdivisions, consolidations or combinations of the Common Shares occurring, in any such case, prior to the Distribution Date. 
  
 Preferred Shares purchasable upon the exercise of Rights will not be redeemable. Each Preferred Share will be entitled to a minimum preferential quarterly
dividend payment of $1.00 per share but will be entitled to an aggregate dividend of 100 times the dividend declared per Common Share. In the event of liquidation, the holders of the Preferred Shares will be entitled to a minimum preferential
liquidation payment of $100 per share but will be entitled to an aggregate payment of 100 times the payment made per Common Share. Each Preferred Share will have one vote per share, voting as a separate class on all matters submitted to holders of
Common Shares. Finally, in the event of any merger, consolidation or other transaction in which Common Shares are exchanged, each Preferred Share will be entitled to receive 100 times the amount received per Common Share. These rights are protected
by customary antidilution provisions. 
  
 Because of the nature of
the Preferred Shares’ dividend and liquidation rights, the economic value of the one one-hundredth interest in a Preferred Share purchasable upon exercise of each Right should approximate the value of one Common Share. 
  
 In the event that any person becomes an Acquiring Person (a “Flip-In
Event”), each holder of a Right (except as otherwise provided in the Rights Agreement) 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 that are, or (under certain circumstances
specified in the Rights Agreement) were, or subsequently become beneficially owned by an Acquiring Person, related persons and transferees will be null and void. 
  

 C-2 








 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 each holder of a Right (except as otherwise provided in the Rights Agreement) 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. 
  
 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 Preferred Shares will be issued (other than fractions which are integral multiples of one one-hundredth of a Preferred Share, which may, at the election of the Company be evidenced by depositary receipts). In lieu
thereof, an adjustment in cash will be made based on the market price of the Preferred 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 and until the first occurrence of a Flip-Over Event may be paid in Common Shares having an equivalent value. 
  
 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 any Acquiring Person which have become void), in whole or in part, at an exchange ratio of one Common Share, or one one-hundredth of a Preferred 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 a person becoming an Acquiring Person, the Board of Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.001 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 amendments that would change the Redemption Price, the Purchase
Price or the Final Expiration Date of the Rights, 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
