RIGHTS AGREEMENT

Agreement, dated as of July 26, 2005, between Eagle DE, Inc., a Delaware corporation to be renamed Entegris, Inc. (the “Company”), and Xxxxx Fargo Bank, N.A. (the “Rights Agent”).

The Company has entered into an Agreement and Plan of Merger by and among Entegris, Inc., a Minnesota corporation (“Entegris”), Mykrolis Corporation, a Delaware corporation (“Mykrolis”) and the Company, dated as of March 21, 2005 (the “Merger Agreement”) that among other things provides for the merger of Mykrolis with and into the Company (the “Merger”).

The Board of Directors of the Company has authorized and declared, subject to the Merger becoming effective, a dividend of one preferred share purchase right (a “Right”) for each share of Common Stock, par value $0.01 per share, of the Company (a “Common Share”) outstanding on the Close of Business (as defined in this Agreement) on August 8, 2005 (the “Record Date”), each Right initially representing the right to purchase one-hundredth of a Preferred Share (as defined in this Agreement), upon the terms and subject to the conditions set forth in this Agreement, and has further authorized the issuance of one Right (as such number may hereafter be adjusted pursuant to Section 11) with respect to each additional Common Share that shall become outstanding at any time between the Record Date and the earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date (each as defined in this Agreement), and certain additional shares of Common Stock that shall become outstanding after the Distribution Date as provided in Section 22 of this Agreement, each Right representing the right to purchase one-hundredth of a Preferred Share, or such different amount and/or kind of securities as shall be hereinafter provided.

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

Section 1. Certain Definitions.

For purposes of this Agreement, the following terms have the meanings indicated:

“Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner after the effective time of the Merger of 15% or more of the Common Shares of the Company then outstanding but shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii) any employee benefit plan of the Company or any Subsidiary of the Company, or (iv) any entity holding Common Shares for or pursuant to the terms of any such employee benefit plan (each Person described in clauses (i) through (iv) is called an “Exempt Person”). An entity other than the Company or any Subsidiary of the Company holding Common Shares for or pursuant to the terms of an employee benefit plan of the Company or any Subsidiary of the Company and in addition being the Beneficial Owner of Common Shares that are not held for or pursuant to the terms of any such plan shall be deemed to constitute an Acquiring Person, notwithstanding anything herein stated, if, but only if, it, together with its Affiliates and Associates, shall be the Beneficial Owner of 15% or more, exclusive of the Common Shares held by it for or pursuant to the terms of any such plan, of the Common Shares then outstanding. Notwithstanding the foregoing, (1) no Person shall become an “Acquiring Person” as the result of an acquisition of Common Shares by the Company that, 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, together with all Affiliates or Associates of such Person, shall so become the Beneficial Owner of 15% or more of the

- 2 -

Common Shares of the Company then outstanding by reason of an acquisition of Common Shares by the Company and shall, after such share purchases by the Company, become the Beneficial Owner of an additional 1% of the outstanding Common Shares of the Company, then such Person (unless such Person is an Exempt Person) shall be deemed to be an “Acquiring Person”; and (2) 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, has become such inadvertently (including, without limitation, because (A) such Person was unaware that it beneficially owned a percentage of the Common Shares that would otherwise cause such Person to be an “Acquiring Person” or (B) such Person was aware of the extent of its Beneficial Ownership but had no actual knowledge of the consequences of such Beneficial Ownership under this Agreement) and without any intention of changing or influencing control of the Company, 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, then such Person shall not be deemed to have become an “Acquiring Person” for any purposes of this Agreement.

“Act” means the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder.

“Adjustment Date” has the meaning set forth in Section 11(a)(iii).

“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.

“Aggregate Market Value” has the meaning set forth in Section 11(a)(iii)(A)(1).

(ii) that such Person or any of such Person’s Affiliates or Associates has, directly or indirectly, (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), written or otherwise, or upon the exercise of conversion rights, exchange rights, other rights (other than the Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed to be the Beneficial Owner of, or to beneficially own or to have beneficial ownership of, any securities pursuant to paragraph (i), (ii) or (iii) hereof solely because such securities are tendered pursuant to a tender or exchange offer made pursuant to, and in accordance with, the applicable rules and regulations promulgated under the Exchange Act 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 (including without limitation pursuant to any agreement, arrangement or understanding, written or otherwise); provided, however, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own or have beneficial ownership of, any security pursuant to paragraph (i), (ii) or (iii) hereof solely because of the right to vote such security pursuant to an agreement, arrangement or understanding if the agreement, arrangement or

- 4 -

understanding to vote such security (1) arises solely from a revocable proxy or consent given to such Person or any of such Person’s Affiliates or Associates in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations promulgated under the Exchange Act and (2) is not also then reportable by such Person or any of such Person’s Affiliates or Associates on Schedule 13D under the Exchange Act (or any comparable or successor report) as being beneficially owned by such Person or any of such Person’s Affiliates or Associates; or

(iii) that are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) 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), written or otherwise, for the purpose of acquiring, holding, voting (except to the extent contemplated by the proviso to section (B) of the immediately preceding paragraph (ii)) or disposing of any securities of the Company.

Notwithstanding anything in these definitions of Beneficial Owner, beneficially own or 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 that such Person would be deemed to own beneficially hereunder.

“common share equivalents” shall have the meaning set forth in Section 11(a)(iii)(C)(3).

The Company may from time to time appoint such co-Rights Agents as it may deem necessary or desirable.

Section 3. Issue of Right Certificates.

(a) Until the latest of (A) (i) the tenth Business Day after the Shares Acquisition Date or (ii) the tenth Business Day (or such later date as may be determined by action of the Board of Directors prior to such time as any Person becomes an Acquiring Person) after the date of the commencement or the first public announcement (as defined in Rule 14d-2 promulgated under the Exchange Act) by any Person (other than an Exempt Person) of the making of, or intent to make, a tender or exchange offer the consummation of which would result in any Person (other than an Exempt Person) becoming the Beneficial Owner of Common Shares aggregating 15% or more of the then outstanding Common Shares, whichever is earlier, (B) such date or the occurrence of such event thereafter which is on or after the Record Date, as may be determined by action of the Board of Directors prior to the Distribution Date as determined by the earlier of (A)(i) or (A)(ii), or (C) such date or the occurrence of such event thereafter as may be determined by action of the Board of Directors from time to time prior to the date or the occurrence of such event on which the Distribution Date would have occurred, but for the most recent determination by the Board of Directors pursuant to this Section 3(a) (including any such date that is after the date of this Agreement and before the issuance of the Rights; the latest of such dates being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced

- 8 -

(subject to the provisions of Section 3(b)) by the certificates for Common Shares registered in the names of the holders thereof (which certificates shall also be deemed to be Right Certificates when the context so requires) and not by separate Right Certificates, and (y) the right to receive Right Certificates will be transferable only in connection with the transfer of Common Shares. As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign, and the Company will send or cause to be sent (and the Rights Agent will, if requested, at the expense of the Company, send) by first-class, insured, postage-prepaid mail, to each record holder of Common Shares as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, one or more Right Certificates evidencing one Right for each Common Share so held, subject to adjustment pursuant to Section 11(i). If an adjustment in the number of Rights per Common Share has been made pursuant to Section 11(i), at the time Right Certificates are distributed, the Company may, to the extent provided in Section 14(a), make the necessary and appropriate rounding adjustments (as set forth in Section 14(a)) so that Right Certificates are distributed representing only whole numbers of Rights and pay cash in lieu of fractional Rights pursuant to Section 14(a). As of and after the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

(b) On the Record Date, or as soon as practicable thereafter, the Company will send a copy of the Summary of Rights by first-class, postage-prepaid mail, to each record holder of Common Shares as of the Close of Business on the Record Date, at the address of such holder shown on the records of the Company. With respect to certificates for Common Shares outstanding as of the Record Date, until the earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date, the Rights will

- 9 -

be evidenced by such certificates registered in the names of the holders thereof and the registered holders of the Common Shares shall also be the registered holders of the associated Rights. Until the earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date, the surrender for transfer of any certificate for Common Shares (including without limitation the surrender for transfer of any certificate for Common Shares outstanding on the Record Date), with or without a copy of the Summary of Rights attached thereto, shall also constitute the transfer of the Rights associated with the Common Shares evidenced thereby.

(c) Certificates for Common Shares that become outstanding (including, without limitation, reacquired Common Shares referred to in the last sentence of this paragraph (c)) after the Record Date but prior to the earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date or as provided in Section 22 of this Agreement, shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement between Entegris, Inc. and Xxxxx Fargo Bank, N.A., as Rights Agent, dated as of July 26, 2005, as it may from time to time be amended or supplemented pursuant to its terms (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 the Company. 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. The Company will mail to the holder of this certificate a copy of the Rights Agreement without charge after receipt of a written request therefor from such holder. Under certain circumstances, Rights that are or were acquired or beneficially owned by an Acquiring Person or any Affiliate or Associate thereof (as defined in the Rights Agreement) may become null and void.

- 10 -

With respect to such certificates containing the foregoing legend, until the earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date, the Rights associated with the Common Shares represented by certificates shall be evidenced by such certificates alone, the registered holders of the Common Shares shall also be the registered holders of the associated Rights 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 earliest of the Close of Business on the Distribution Date, the Redemption Date or the Close of Business on the Final Expiration Date, any Rights associated with such Common Shares shall be deemed canceled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Shares that are no longer outstanding.

Section 4. 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 or automated quotation system on which the Rights may from time to time be listed, or to conform to usage or to reflect adjustments to the Rights made pursuant to this Agreement. Subject to the other provisions of this Agreement, the Right Certificates whenever distributed shall entitle the holders thereof to purchase such number of one-hundredths of a Preferred Share

- 11 -

as shall be set forth therein at the Purchase Price per one-hundredth of a Preferred Share, but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price shall be subject to adjustment as provided herein.

Section 5. Countersignature and Registration.

(a) The Right Certificates shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, any of its Vice Presidents, or its Treasurer, either manually or by facsimile signature, shall have affixed thereto the Company’s seal, if any, or a facsimile thereof, and shall be attested by the Secretary or any Assistant Secretary of the Company, either manually or by facsimile signature. The Right Certificates shall be countersigned by the Rights Agent and shall not be valid for any purpose unless so countersigned, either manually or by facsimile. In case any officer of the Company who shall have signed or whose facsimile signature shall appear on 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 person 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 Person 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 of the 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.

- 12 -

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

(a) Subject to the provisions of Section 14, at any time after the Close of Business on the Distribution Date, and prior to the earlier of the Redemption Date or the Close of Business on 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) or that have been exchanged pursuant to Section 24) 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-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, subject to Section 14, 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 by the registered holder 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. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate until the registered holder shall have duly completed and executed the form of assignment on the reverse side of such Right Certificate and shall have provided such

- 13 -

additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) of such Right Certificate or Affiliates or Associates thereof as the Company or Rights Agent shall reasonably request.

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

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

(a) The registered holder of any Right Certificate (other than a holder whose Rights have become void pursuant to Section 11(a)(ii) or have been exchanged pursuant to Section 24) may exercise the Rights evidenced thereby 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 completed and executed, to the Rights Agent at its principal office, together with payment of the Purchase Price for each one-hundredth of a Preferred Share as to which the Rights are exercised, prior to the earliest of (i) the Close of Business on the Final Expiration Date, (ii) the Redemption Date, or (iii) the time at which such Rights are exchanged pursuant to Section 24.

(b) The purchase price for each one-hundredth of a Preferred Share to be purchased upon the exercise of a Right shall initially be Fifty Dollars ($50.00) (the “Purchase

- 14 -

Price”), shall be subject to adjustment from time to time as provided in Sections 11 and 13 and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below.

(c) Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase and certification duly executed, accompanied by payment of the Purchase Price for the number of Preferred 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 by cash, certified check, cashier’s check or money order payable to the order of the Company, the Rights Agent shall, subject to Section 20(k), thereupon promptly (i) (A) requisition from any transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent for such 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) if the Company shall have elected to deposit the total number of Preferred Shares issuable upon exercise of Rights under this Agreement with a depositary agent, requisition from the depositary agent depositary receipts representing such number of Preferred Shares 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) and the Company hereby directs any such depositary agent to comply with such request, (ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuance of fractional interests in shares (other than fractions that are integral multiples of one-hundredth of a Preferred Share) in accordance with Section 14, (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 for fractional interests to or upon the order of the registered holder of such Right Certificate.

- 15 -

(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 and delivered to the registered holder of such Right Certificate or to such holder’s duly authorized assigns, subject to the provisions of Section 14.

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

Section 8. Cancellation 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 canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Rights Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all canceled Right Certificates to the Company.

- 16 -

Section 9. Status and Availability of Preferred Shares.

(a) 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 Preferred Shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and non-assessable shares.

(b) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges that 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 that 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 or depositary receipts 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 or depositary receipts 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 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.

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

- 17 -

(d) The Company covenants and agrees that on and after the Distribution Date so long as the Preferred Shares (and/or, following a Section 11(a)(ii) Event, Common Shares and/or similar units of equivalent preferred shares) issuable upon the exercise of Rights may be listed on any national securities exchange or quoted on the Nasdaq National Market or comparable system, the Company shall use its best efforts to cause all shares (or similar units) reserved for such issuance to be listed on such exchange or quoted on the Nasdaq National Market or comparable system upon official notice of issuance upon such exercise. The Company shall use its best efforts (i) to file, as soon as practicable following the earliest date after the first occurrence of a Section 11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined in accordance with this Agreement, or as soon as is required by law following the Distribution Date, as the case may be, a registration statement under the Act, with respect to the securities issuable upon exercise of the Rights on an appropriate form, (ii) to cause such registration statement to become effective as soon as practicable after such filing, and (iii) to cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, or (B) the Final Expiration Date or earlier redemption of the Rights. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or “blue sky” laws of the various states of the United States in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time not to exceed 90 days after the date set forth in clause (i) of this Section 9(d), the exercisability of the Rights in order to prepare and file such registration statement or to permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been

- 18 -

temporarily suspended. The Company shall thereafter issue a public announcement at such time as the suspension is no longer in effect. The Company shall notify the Rights Agent whenever it makes a public announcement pursuant to this Section 9(d) and give the Rights Agent a copy of such announcement. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction unless the requisite qualification in such jurisdiction shall have been obtained.

Section 10. 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. Prior to the exercise of the Rights evidenced thereby, the holder of a Right Certificate shall not be entitled to any rights of a holder of Preferred Shares for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

Section 11. Adjustment of Purchase Price, Number and Kind of Shares or Number of Rights.

The Purchase Price, the number and kind of 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.

- 19 -

(a)(i) In the event the Company shall at any time after the date of this Agreement (A) declare or pay a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares into a greater number of 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 shall be proportionately adjusted, and the number and kind of shares of capital stock issuable on such date pursuant to the exercise of the Rights shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect (and any applicable transfer taxes), the aggregate number and kind of shares of capital stock that, if such Right had been exercised immediately prior to such date, 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 that 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 before, any adjustment required pursuant to Section 11(a)(ii).

(ii) Subject to the following paragraph of this subparagraph (ii) and to Section 24 of this Agreement, in the event any Person shall become an Acquiring Person, each holder of

- 20 -

a Right, subject to Section 11(a)(iii), shall thereafter have a right to receive, upon exercise thereof after the Distribution Date by payment of the amount equal to the product of the number of one-hundredths of a Preferred Share that would otherwise be issuable upon exercise of a Right and the then current Purchase Price, in accordance with the terms of this Agreement, 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-hundredths of a Preferred Share for which a Right would be exercisable immediately before the occurrence of the Section 11(a)(ii) Event that caused such Person to become an Acquiring Person and (y) dividing that product by 50% of the then current per share market price of the Company’s Common Shares (determined pursuant to Section 11(d)) on the date such Person became an Acquiring Person. In the event that any Person shall become an Acquiring Person and the Rights shall then be outstanding, the Company shall not take any action that would eliminate or diminish the benefits intended to be afforded by the Rights.

From and after the occurrence of a Section 11(a)(ii) Event or a Section 13 Event, any Rights that are or were acquired or beneficially owned by any Acquiring Person (or any Associate or Affiliate of such Acquiring Person) on or after the earlier of (x) the date of such event and (y) the Distribution Date shall be void and any holder of such Rights shall thereafter have no right to exercise such Rights or any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. 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

- 21 -

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 or any Associate or Affiliate of such Acquiring Person whose Rights would be void pursuant to the preceding sentence shall be canceled. The Company shall use all reasonable efforts to ensure that the provisions of this Section 11(a)(ii) are complied with, but shall have no liability to any holder of a Right Certificate or other Person as a result of its failure in good faith to make any determinations with respect to an Acquiring Person or its Affiliates or Associates.

(iii) In the event that, on the date of the occurrence of a Section 11(a)(ii) Event (the “Adjustment Date”), the number of Common Shares that are authorized by the Company’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than upon exercise of the Rights, are not sufficient to permit the holder of each Right to purchase the number of Common Shares to which such holder would be entitled upon the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of paragraph (a) of this Section 11, then the exercise price of a Right and the number of Common Shares to be delivered by the Company upon exercise of a Right shall be further adjusted as provided in this subparagraph (iii).

(A) Definitions:

(1) The “Aggregate Market Value” is the product of the number of Available Shares times the current per share market price of the Common Shares on the Adjustment Date, determined as provided in Section 11(d).

(2) The “Available Shares” are all Common Shares authorized by the Company’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than upon exercise of the Rights.

- 22 -

(3) The “Exercise Price” is the amount of payment that must be made by a holder of a Right in connection with the exercise of one Right immediately before the Adjustment Date.

(4) The “Deficiency” is the amount by which two times the Exercise Price exceeds the quotient obtained by dividing the Aggregate Market Value by the number of Rights remaining outstanding immediately before the Adjustment Date (the “Remaining Rights”) (which number shall not include the Rights that are beneficially owned by any Acquiring Person (or any Associate or Affiliate thereof) or were beneficially owned by any Acquiring Person (or any Associate or Affiliate thereof) after the Acquiring Person became an Acquiring Person that shall have become void pursuant to Section 11(a)(ii)).

(B) If the Deficiency is less than or equal to the Exercise Price, then

(1) the number of Common Shares to be delivered by the Company upon exercise of a Right shall be adjusted to equal the number of Available Shares divided by the number of Remaining Rights; and

(2) the amount of cash required to be delivered by a holder of a Right upon the exercise thereof shall be adjusted (the “New Exercise Price”) to equal the Exercise Price minus the Deficiency, notwithstanding anything to the contrary provided in Section 11(a)(ii); provided, however, that in no event will the New Exercise Price be less than the aggregate par value of the Common Shares required to be delivered upon the exercise of one Right pursuant to subparagraph (B)(1) above.

- 23 -

(C) If the Deficiency is greater than the Exercise Price, then

(1) the number of Common Shares to be delivered by the Company upon exercise of a Right shall be adjusted to equal the quotient obtained by dividing the Exercise Price by the per share market price of the Common Shares on the Adjustment Date;

(2) the New Exercise Price shall equal the aggregate par value of the Common Shares required to be delivered upon the exercise of one Right pursuant to subparagraph (C)(1) above; and

(3) in lieu of issuing Common Shares (in whole or in part upon the exercise of Rights) the Company may issue, upon the exercise of Rights at the New Exercise Price notwithstanding anything to the contrary provided in Section 11(a)(ii) other equity securities of the Company to the extent they shall be authorized (including without limitation, shares, or units or fractions of shares of preferred stock, which may include Preferred Shares) that the Board of Directors of the Company has determined have substantially the same value, voting rights, dividend rights and other rights as the Common Shares (such equity securities are herein called “common share equivalents”). To the extent that such common share equivalents (or fractions thereof) are substituted for Common Shares upon exercise of the Rights following the occurrence of a Section 11(a)(ii) Event, they shall be substituted on a pro rata basis with respect to all Rights (other than Rights that are beneficially owned by any Acquiring Person (or any Associate or

- 24 -

Affiliate thereof) or were beneficially owned by any Acquiring Person (or any Associate or Affiliate thereof) after the Acquiring Person became an Acquiring Person that shall have become void pursuant to Section 11(a)(ii)). Such common share equivalents shall not be included in Available Shares, and all of the Available Shares shall be reserved, as of the Adjustment Date, for issuance on a pro rata basis, upon exercise of the Rights and may not be substituted for with common share equivalents upon the exercise of any Right except to the extent that the number of Common Shares required to be delivered under subparagraph (C)(1) upon the exercise of such Right exceeds the quotient of the number of Available Shares divided by the number of Remaining Rights.

(D) If, at the time any adjustment is required pursuant to this Section 11(a)(iii), the Common Shares have no par value, then for the purpose of this Section 11(a)(iii), the par value of the Common Shares shall be deemed to be $0.01 per share.

(E) If there shall not be sufficient Available Shares (or common share equivalents) to permit the exercise in full of the Rights in accordance with this subparagraph (iii), the Company shall use its best efforts to cause the authorization of sufficient additional Common Shares or common share equivalents to permit such exercise and, if the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional Common Shares or common share equivalents could be authorized to permit exercise in full of the Rights, the Company may suspend the exercisability of the Rights for a period of not more than 90 days (and not beyond the Final Expiration Date), in order that the Company may seek stockholder approval for the authorization of such additional Common Shares or common share equivalents. In the

- 25 -

event of any such suspension, the Company shall make a public announcement, and shall deliver to the Rights Agent a statement, stating that the exercisability of the Rights has been temporarily suspended. At such time as the suspension is no longer in effect, the Company shall make another public announcement, and deliver to the Rights Agent a statement, so stating. If, despite the best efforts of the Company, there shall not be sufficient Common Shares (or common share equivalents) which are authorized by the Company’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than upon exercise of the Rights to permit the exercise in full of the Rights in accordance with this subparagraph (iii), the Board of Directors of the Company in good faith shall establish a system for treatment of exercising Rights holders on as pro rata a basis as practicable based upon the number of Common Shares for which Rights are exercised and the number of Available Shares (and common share equivalents).

(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 or equivalent 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 determined pursuant to Section 11(d)) on such record date, the Purchase Price to be in effect after such record date shall be adjusted by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the

- 26 -

numerator of which shall be the number of Preferred Shares outstanding on such record date plus the number of Preferred Shares that 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 per share 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 and shall be binding on the Rights Agent and the holders of the Rights. 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 that 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 cash or non-cash assets (other than a regular

- 27 -

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 price of the Preferred Shares (as determined pursuant to 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 and shall be binding on the Rights Agent and the holders of the Rights) of the portion of the cash or non-cash assets or evidences of indebtedness so to be distributed on, 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 that 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 (A) a dividend or distribution on such Security payable in such Security or securities convertible into

- 28 -

such Security (other than the Rights), or (B) 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 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 Security is 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 or reported 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. Except as provided in Section 11(d)(ii) with respect to Preferred Shares, if on any such day no professional market maker is making a market in the Security, the fair value of such Security on such day 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 and shall be binding on the Rights Agent and the holders of Rights) shall be used in lieu of the closing price

- 29 -

for such day. 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) If the Preferred Shares are not publicly held or listed or traded in a manner described in Section 11(d)(i), then, notwithstanding anything to the contrary provided in Section 11(d)(i), 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 as determined pursuant to Section 11(d)(i) (appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date of this Agreement) multiplied by one hundred. If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, the “current per share market price” of the Preferred Shares 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.

(e) Anything herein to the contrary notwithstanding, except as provided in the third sentence of this Section 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 that 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 millionth of a Preferred Share, or one ten-thousandth of any other share or security, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11, but for the first sentence of this Section 11(e), shall be made no later than the earlier of (1) three years from the date of the transaction that requires such adjustment or (2) the Final Expiration Date.

- 30 -

(f) If as a result of an adjustment made pursuant to Section 11(a) or Section 13(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, the number of such other shares so receivable upon exercise of any Right shall thereafter 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, 13 and 14 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 one-hundredths of a Preferred Share (or other securities) 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 Sections 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 one-hundredths of a Preferred Share (calculated to the nearest one-millionth of a Preferred Share) obtained by (i) multiplying (x) the number of one-hundredths 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.

- 31 -

(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-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-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 ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been distributed, shall be at least ten days later than the date of the public announcement. If Right Certificates have been distributed, 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, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all the Rights to which

- 32 -

such holders shall be entitled after such adjustment. Right Certificates to be so distributed shall be issued, executed and countersigned in the manner provided for herein, may bear, at the option of the Company, the adjusted Purchase Price, 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-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-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 one-hundredth of the then par value, if any, of the Preferred Shares issuable upon exercise of the Rights, the Company shall take any corporate action that may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and non-assessable 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 Preferred Shares and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Shares and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due xxxx or other appropriate instrument evidencing such holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment.

- 33 -

(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 the Board of Directors of the Company in its sole discretion shall determine to be advisable in order that any (i) subdivision, combination or consolidation of the Preferred Shares, (ii) issuance wholly for cash of any Preferred Shares at less than the current per share market price, (iii) issuance wholly for cash of Preferred Shares or securities that by their terms are convertible into or exchangeable for Preferred Shares, (iv) dividends on Preferred Shares payable in Preferred Shares or (v) issuance of any rights, options or warrants referred to hereinabove in Section 11(b), hereafter made by the Company to holders of its Preferred Shares shall not be taxable to such stockholders.

(n) Anything in this Agreement or the Rights to the contrary notwithstanding, if at any time after the date of this Agreement and before the Distribution Date, the Company shall (i) declare or pay any dividend on the Common Shares payable in Common Shares or (ii) effect a subdivision, combination or consolidation of the Common Shares (by reclassification or otherwise than by payment of dividends on the Common Shares payable in Common Shares) into a greater or lesser number of Common Shares, then in any such case (x) the number of one-hundredths of a Preferred Share purchasable after such event upon proper exercise of each Right shall be determined by multiplying the number of one-hundredths of a Preferred Share so purchasable immediately before such event by a fraction, the numerator of which is the number of Common Shares outstanding immediately before such event and the denominator of which is the number of Common Shares outstanding immediately after such event and (y) each Common Share outstanding immediately after such event shall have issued with respect to it that number of Rights that each Common Share outstanding immediately before such event had issued with

- 34 -

respect to it. The adjustments provided for in this Section 11(n) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is effected. If an event occurs that would require an adjustment under Section 11(a)(ii) and this Section 11(n), the adjustments provided for in this Section 11(n) shall be in addition to, and before, any adjustment required pursuant to Section 11(a)(ii).

Section 12. Certificate of Adjustment.

Whenever an adjustment is made as provided in Sections 11 and 13, 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 or the Preferred Shares a copy of such certificate and (c) if such adjustment occurs following a Distribution Date, mail a brief summary thereof to each holder of a Right Certificate in accordance with Section 25. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and shall not be obligated or responsible for calculating any adjustment nor shall it be deemed to have knowledge of such an adjustment unless and until it shall have received such certificate.

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

(a) In the event that, at any time after a Person becomes an Acquiring Person, directly or indirectly, (i) the Company shall consolidate with, or merge with and into, any other Person, and, if a merger, the Company shall not be the continuing or surviving corporation of such merger, (ii) any Person shall merge with and into the Company and the Company shall be the continuing or surviving corporation of such merger and, in connection with such consolidation or merger, all or part of the Common Shares shall be changed into or exchanged

- 35 -

for stock or other securities of any other Person (or the Company) or cash or any other property (except as a result of the exercise of statutory appraisal rights), or (iii) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one or more transactions, assets or earning power aggregating 50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole and taken at net asset value as stated on the financial records of the Company and determined on a consolidated basis with generally accepted accounting principles consistently applied) to any other Person or Persons (other than the Company or one or more of its wholly-owned Subsidiaries), then, and in each such case, proper provision shall be made so that (A) each holder of a Right (except as otherwise provided herein) shall thereafter have the right to receive, upon the exercise thereof after the Distribution Date by payment of an amount equal to the product of the number of one-hundredths of a Preferred Share that would otherwise be issuable upon exercise of a Right and the then current Purchase Price in accordance with the terms of this Agreement and in lieu of Preferred Shares, such number of validly authorized and issued, fully paid, nonassessable and freely tradable Common Shares of the Principal Party (as defined below), not subject to any liens, encumbrances, rights of first refusal or adverse claims, as shall be equal to the result obtained by (x) multiplying the then current Purchase Price by the number of one-hundredths of a Preferred Share for which a Right is, immediately before the occurrence of the Section 13 Event, exercisable and (y) dividing that product by 50% of the then current per share market price of the Common Shares of such Principal Party (determined pursuant to Section 11(d)) on the date of consummation of such Section 13 Event; (B) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such consolidation, merger, sale or transfer, all the obligations and duties of the Company pursuant to this Agreement; (C) the term “Company”

- 36 -

shall thereafter be deemed to refer to such Principal Party; and (D) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of its Common Shares to permit the exercise of all outstanding Rights) in connection with the consummation of any such transaction as may be necessary to ensure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to the Common Shares thereafter deliverable upon the exercise of the Rights.

(b) “Principal Party” shall mean:

(i) in the case of any transaction described in clauses (i) or (ii) of the first sentence of Section 13(a), the Person (including, without limitation, the Company as successor thereto or as the surviving corporation) that is the issuer of any securities into which Common Shares of the Company are converted in such merger or consolidation or if no securities are so issued, the Person that is the other party to such merger or consolidation; or

(ii) in the case of any transaction described in clause (iii) 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, (A) if the Common Shares of such Person are not at such time, and have not continuously over the preceding 12 month period been 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 (B) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Shares of two or more of which are and have been so registered, “Principal Party” shall refer to whichever of such Persons is the issuer of the Common Shares having the greatest aggregate market value.

- 37 -

(c) The Company covenants and agrees that it shall not consummate any Section 13 Event unless (i) the Principal Party shall have a sufficient number of shares authorized by the Principal Party’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than upon exercise of the Rights to permit the exercise in full of the Rights in accordance with this Section 13 and (ii) 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 Section 13 Event, such Principal Party shall: (A) prepare and file a registration statement under 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 (x) become effective as soon as practicable after such filing and (y) remain effective (with a prospectus at all times meeting the requirements of the Act) until the Final Expiration Date, and (B) deliver to holders of the Rights historical financial statements of such Principal Party and each of its Associates and Affiliates which comply in all respects with the requirements for registration on Form 10 under the Securities Exchange Act of 1934, as amended.

(d) The Company shall not enter into any transaction of the kind referred to in this Section 13 if at the time of such transaction there are any rights, warrants, instruments or securities outstanding or any agreements or arrangements that, as a result of the consummation of such transaction, would eliminate or substantially diminish the benefits intended to be afforded by the Rights.

(e) The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers.

- 38 -

(f) For purposes hereof, the “earning power” of the Company and its Subsidiaries shall be determined in good faith by the Company’s Board of Directors on the basis of the operating earnings of each business operated by the Company and its Subsidiaries during the three fiscal years preceding the date of such determination (or, in the case of any business not operated by the Company or any Subsidiary during three full fiscal years preceding such date, during the period such business was operated by the Company or any Subsidiary).

Section 14. Fractional Rights and Fractional Shares.

(a) The Company shall not be required to issue fractions of Rights or to distribute Right Certificates that evidence fractional Rights. In lieu of such fractional Rights, there may 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,

- 39 -

as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not so quoted or reported 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 in lieu of the closing price for such day.

(b) The Company shall not be required to issue fractions of Preferred Shares (other than fractions that are integral multiples of one-hundredth of a Preferred Share, or, if a Right shall then be exercisable for a fraction other than one-hundredth of a Preferred Share, integral multiples of that fraction) upon exercise of the Rights or to distribute certificates which evidence fractions of Preferred Shares (other than fractions that are integral multiples of one-hundredth of a Preferred Share, or, if a Right shall then be exercisable for a fraction other than one-hundredth of a Preferred Share, integral multiples of that fraction). Fractions of Preferred Shares in integral multiples of one-hundredth of a Preferred Share or, if a Right shall then be exercisable for a fraction other than one-hundredth of a Preferred Share, integral multiples of that fraction 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-hundredth of a Preferred Share, or, if a Right shall then be exercisable for a fraction other than one-hundredth of a Preferred Share, integral multiples of that fraction, the Company may pay to each registered holder of Right Certificates at the time such Rights are

- 40 -

exercised as herein provided an amount in cash equal to the same fraction of the current market value of one Preferred Share. For the 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)) for the Trading Day immediately prior to the date of such exercise or if the closing price is not determinable pursuant to the second sentence of Section 11(d)(i), the current market value of a Preferred Share shall be determined pursuant to Section 11(d)(ii).

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

Section 15. Rights of Action.

All rights of action in respect of this Agreement, excepting the rights of action given to the Rights Agent under Section 18, 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) may, 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), on such holder’s own behalf and for such holder’s own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, such holder’s right to exercise the Rights evidenced by such Right Certificate (or, prior to the Distribution Date, the associated Common Shares 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

- 41 -

would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

Section 16. Agreement of Right Holders.

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

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

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

(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;

(d) the Company may issue Rights on or after the Record Date but before the Distribution Date, and in certain instances after the Distribution Date, as provided in this Agreement; and

- 42 -

(e) notwithstanding anything in this Agreement or the Rights to the contrary, the Company, the Rights Agent and the Board of Directors shall not have any liability to any holder of a Right or other Person as a result of the inability of the Company or the Rights Agent 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 of 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.

Section 17. Right Certificate Holder Not Deemed a Stockholder.

No holder, as such, of any Right Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the Preferred Shares or any other securities of the Company that 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 stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 25), 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.

- 43 -

Section 18. Concerning the Rights Agent.

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without 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 or liability in connection therewith. The indemnification provided for hereunder shall survive the expiration of the Rights and the termination of this Agreement. The costs and expenses of enforcing this right of indemnification shall also be paid by the Company.

(b) The Rights Agent may conclusively rely upon and 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 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 its counsel as set forth in Section 20. Notwithstanding anything in this Agreement to the contrary, in no event shall the Rights Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage and regardless of the form of the action.

- 44 -

Section 19. Merger or Consolidation or Change of Name of Rights Agent.

(a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the 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. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

(b) In case at any time the name of the Rights Agent shall be changed and at such time any of the Right Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been

- 45 -

countersigned, the Rights Agent may countersign such Right Certificates either in its prior name or in its changed name; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

Section 20. Duties of Rights Agent.

The Rights Agent undertakes the duties and obligations expressly set forth in this Agreement and no implied duties or obligations shall be read into this Agreement against the Rights Agent. The Rights Agent shall perform those duties and obligations upon the following terms and conditions, by all of which the Company and the holders of Right Certificates (or, prior to the Distribution Date, the Common Shares certificates) by their acceptance thereof, shall be bound:

(a) Before the Rights Agent acts or refrains from acting, it 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 (including, without limitation, the identity of any Acquiring Person and the determination of the “current per share market price”) 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 any one of the Chairman of the Board, the President, a Vice President, the Treasurer or the 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.

- 46 -

(c) The Rights Agent shall be liable hereunder 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 as to 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 execution 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)) or any adjustment required under the provisions of Sections 11 or 13 or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such change or adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after actual notice that such change or adjustment is required); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Preferred Shares or Common Shares to be issued pursuant to this Agreement or any Right Certificate or as to whether any Preferred Shares or Common Shares will, when so issued, be validly authorized and issued, fully paid and nonassessable.

- 47 -

(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 President, a Vice President, the Secretary or the 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 to be taken by it in good faith in accordance with instructions of any such officer. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent under this Agreement and the date on or after which such action shall be taken or such omission shall be effective. The Rights Agent shall not be liable for any action taken by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than ten Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received, in response to such application, written instructions with respect to the proposed action or omission specifying a different action to be taken or omitted.

(h) The Rights Agent and any stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or

- 48 -

become pecuniarily interested in any transaction in which the Company or its Subsidiaries may be interested, or contract with or lend money to the Company or its Subsidiaries 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 its Subsidiaries 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.

(j) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(k) If, with respect to any Right Certificate surrendered to the Rights Agent for exercise or transfer, the form of assignment or form of election to purchase, as the case may be, has either not been duly completed and executed, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company.

(l) The Rights Agent shall not be required to take notice or be deemed to have notice of any fact, event or determination (including, without limitation, any dates or events

- 49 -

defined in this Agreement or the designation of any Person as an Acquiring Person, Affiliate or Associate) under this Agreement unless and until the Rights Agent shall be specifically notified in writing by the Company of such fact, event or determination.

Section 21. Change of Rights Agent.

The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Shares and Preferred Shares by registered or certified 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 and Preferred Shares by registered or certified 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 such holder’s 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 any state of the United States, in good standing, which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $100 million or (b) an affiliate of a corporation described in clause (a) of this sentence.

- 50 -

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 Preferred Shares. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

Section 22. Issuance of New Right Certificates.

Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Right Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of Common Stock following the Distribution Date and prior to the earlier of the Redemption Date and the Close of Business on the Final Expiration Date, the Company may with respect to shares of Common Stock so issued or sold pursuant to (i) the exercise of stock options, (ii) under any employment plan or arrangement, (iii) upon the exercise, conversion or exchange of securities, notes or debentures issued by the Company or (iv) a contractual obligation of the Company, in each case existing prior to the Distribution Date, issue Right Certificates representing the appropriate number of Rights in connection with such issuance or sale.

- 51 -

Section 23. Redemption.

(a) 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 $0.01 per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the “Redemption Price”). The Redemption Price shall be payable in cash by the Company. The redemption of the Rights by the Board of Directors may be made effective at such time, on such basis and subject to such conditions as the Board of Directors in its sole discretion may establish. Except for the obligation of the Company to pay the Redemption Price, the Board of Directors and the Company shall not have any liability to any Person as a result of the redemption of Rights pursuant to the terms of this Section 23.

(b) Immediately upon the time of the effectiveness of the redemption of the Rights pursuant to paragraph (a) of this Section 23 or such earlier time as may be determined by the Board of Directors of the Company in the action ordering such redemption (although not earlier than the time of such action) (such time the “Redemption Date”), and without any further action and without any notice, the right to exercise the Rights shall 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 and shall give notice of such redemption to the Rights Agent; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Promptly after such action of the Board of

- 52 -

Directors ordering the redemption of the Rights pursuant to paragraph (a), 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; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. If the payment of the Redemption Price is not included with such notice, each such notice shall 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, other than in connection with the purchase of Common Shares prior to the Distribution Date.

Section 24. Exchange.

(a) The Board of Directors of the Company may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 11(a)(ii)) for Common Shares with each Right to be exchanged for such number of Common Shares as shall equal the result obtained by dividing (i) the Exercise Price (as defined in Section 11(a)(iii)(A)(3)) by (ii) the current per share market price of the Common Shares (determined pursuant to Section 11(d)) on the date the Rights first become exercisable for Common Shares pursuant to Section 11(a)(ii) (such number of shares being hereinafter referred to as the “Exchange Ratio”). The Exchange Ratio shall be appropriately adjusted to reflect any stock split, stock dividend or similar transaction affecting the Common Shares that occurs after

- 53 -

the date the Rights first become exercisable for Common Shares pursuant to Section 11(a)(ii). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than an Exempt Person), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the Common Shares then outstanding.

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

(c) If there shall not be sufficient Common Shares authorized by the Company’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than the exchange of the Rights to permit an

- 54 -

exchange of Rights as contemplated in accordance with this Section 24, the Company, at its option, may substitute Preferred Shares (or equivalent preferred shares) or common share equivalents for Common Shares exchangeable for Rights, at the initial rate of one-hundredth of a Preferred Share (or equivalent preferred share) or one common share equivalent for each Common Share, as appropriately adjusted to reflect stock splits, stock dividends or similar transactions affecting the Common Shares that occur after the Record Date.

(d) In the event that there shall not be sufficient Common Shares, Preferred Shares, equivalent preferred shares or common share equivalents authorized by the Company’s certificate of incorporation and not outstanding or subscribed for, or reserved or otherwise committed for issuance for purposes other than upon exchange of Rights, to permit any exchange of Rights as contemplated in accordance with this Section 24, the Company, if its Board of Directors, at its option, shall elect to exchange Rights pursuant to this Section 24, shall take all such action as may be necessary to authorize additional Common Shares, Preferred Shares, equivalent preferred shares or common share equivalents for issuance upon exchange of the Rights.

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

- 55 -

Section 24 or if the closing price is not determinable pursuant to the second sentence of Section 11(d)(i), the current market value of a Common Share shall be determined pursuant to Section 11(d)(i). The Board of Directors and the Company shall not have any liability to any Person as a result of the exchange of Rights pursuant to the terms of this Section 24.

Section 25. Notice of Certain Events.

(a) In case the Company shall after the Distribution Date propose (i) to declare or pay any dividend payable in stock of any class to the holders of its Preferred Shares or to make any other distribution to the holders of its Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer to the holders of its 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 its Preferred Shares (other than a reclassification involving only the subdivision of outstanding Preferred Shares), (iv) to effect any consolidation or merger into or 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 Persons (other than the Company and/or any of its wholly-owned Subsidiaries), (v) to effect the liquidation, dissolution or winding up of the Company, or (vi) to declare or pay any dividend on the Common Shares payable in Common Shares or to effect a subdivision, combination or consolidation of the Common Shares (by reclassification or otherwise than by payment of dividends on Common Shares payable in Common Shares), then, in each such case, the Company shall give to each holder of a Right Certificate, to the extent feasible and in accordance with Section 26, 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

- 56 -

the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the Common Shares and/or 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 ten days prior to the record date for determining holders of the Preferred Shares for purposes of such action, and in the case of any such other action, at least ten days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Common Shares and/or Preferred Shares, whichever shall be the earlier.

(b) In case any Section 11(a)(ii) Event shall occur, then the Company shall as soon as practicable thereafter give to each holder of a Right Certificate, in accordance with Section 26, a notice of the occurrence of such event, which notice shall describe such event and the consequences of such event to holders of Rights under Section 11(a)(ii).

Section 26. Notices.

Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Right Certificate to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, or delivered by hand or express courier services addressed (until another address is filed in writing with the Rights Agent) as follows:

Section 27. Supplements and Amendments.

Prior to the Distribution Date, the Company, upon the vote of a majority of the Board, may from time to time supplement or amend this Agreement without the approval of any holders of Rights. From and after the Distribution Date, the Company may from time to time, upon the vote of a majority of the Board 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 (a) to extend the Final Expiration Date, (b) to cure any ambiguity or to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, or (c) to make any change to or delete any provision hereof or to adopt any other provisions with respect to the Rights which the Company may deem necessary or desirable; provided, however, that from and after such time as any Person becomes an Acquiring

- 58 -

Person, this Agreement shall not be amended or supplemented in any manner which would adversely affect the interests of the holders of Rights (other than an Acquiring Person and its Affiliates and Associates). Any supplement or amendment authorized by this Section 27 will be evidenced by a writing signed by the Company and the Rights Agent. Notwithstanding anything in this Agreement to the contrary, no supplement or amendment that changes the rights and duties of the Rights Agent under this Agreement will be effective against the Rights Agent without the execution of such supplement or amendment by the Rights Agent.

CERTIFICATE OF DESIGNATIONS OF SERIES A JUNIOR

PARTICIPATING PREFERRED CAPITAL STOCK

OF

ENTEGRIS, INC.

(Pursuant to Section 151 of the Delaware General Corporation Law)

Entegris, Inc., a corporation organized and existing under the General Corporation Law of the State of Delaware (the “Corporation”), hereby certifies that the following resolution was adopted by the Board of Directors of the Corporation, in accordance with the provisions of Section 151 of the General Corporation Law at a meeting duly called and held and is in full force and effect:

RESOLVED, that pursuant to the authority granted to and vested in the Board of Directors of this Corporation (hereinafter called the “Board of Directors” or the “Board”) in accordance with the provisions of its Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), a series of Preferred Capital Stock, par value one cent ($0.01) per share (as such par value may be changed from time to time, the “Preferred Shares” or “Preferred Stock”), of the Corporation be, and it hereby is, created and that the designation and number of shares thereof and the relative rights, preferences and limitations of the shares of such series, are as follows:

1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Capital Stock “ (the “Series A Preferred Shares”), and the number of shares constituting such series shall be two million five hundred thousand (2,500,000). The number of shares constituting such series may, unless prohibited by the Certificate of Incorporation or by applicable law of the State of Delaware, be increased or decreased by resolution of the Board of Directors; provided, that no decrease shall reduce the number of Series A Preferred Shares to a number less than the number of shares then outstanding plus the number of shares issuable upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Shares.

2. Dividends and Distributions.

(i) Subject to the rights of the holders of any shares of any series of Preferred Stock (or any similar stock ranking prior and superior to the Series A Preferred Shares), the holders of Series A Preferred Shares, in preference to the holders of Common Stock, par value one cent ($0.01) per share (the “Common Shares” or “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 the first business day of March, June, September and December 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 Series A Preferred Share, or fraction thereof, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment hereinafter set forth, one hundred (100) times the aggregate per share amount of all cash dividends, and one hundred (100) times the aggregate per share amount (payable in kind) of all

A-1

non-cash 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 Dividend Payment Date, since the first issuance of any Series A Preferred Share, or fraction thereof. In the event the Corporation shall at any time after August 8, 2005 declare or pay any dividend on shares of 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 on shares of Common Stock payable in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of Series A Preferred Shares were entitled immediately before such event under clause (b) 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 before such event.

(ii) The Corporation shall declare a dividend or distribution on the Series A Preferred Shares as provided in subparagraph (i) of this paragraph 2 simultaneously with its declaration of a dividend or distribution on the shares of Common Stock (other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock); provided that, if no dividend or distribution shall have been declared on the shares of 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 Shares shall nevertheless be payable, out of funds legally available for such purpose, on such subsequent Quarterly Dividend Payment Date.

(iii) Dividends shall begin to accrue and be cumulative on outstanding Series A Preferred Shares from the Quarterly Dividend Payment Date immediately preceding the date of issue of such Series A Preferred Shares, unless the date of issue of such shares is before 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 Series A Preferred Shares 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 Series A Preferred Shares 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 outstanding at that time. The Board of Directors may fix a record date for the determination of holders of Series A Preferred Shares entitled to receive payment of a dividend or distribution declared thereon, which record date shall be not more than sixty (60) days before the date fixed for the payment thereof.

3. Voting Rights. The holders of Series A Preferred Shares shall have the following voting rights:

(i) Subject to the provision for adjustment hereinafter set forth, each Series A Preferred Share shall entitle the holder thereof to one hundred (100) votes on all matters submitted to a vote of the stockholders of the Corporation. If the Corporation shall at any time after

A-2

August 8, 2005 declare or pay any dividend on Common Stock payable in Common Stock, or effect a subdivision or combination or consolidation of the outstanding Common Stock (by reclassification or otherwise) into a greater or lesser number of shares of Common Stock, then in each such case the number of votes per share to which holders of Series A Preferred Shares were entitled immediately before such event shall be adjusted by multiplying such number 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 before such event.

(ii) Except as otherwise provided herein, in any other Certificate of Designations creating a series of Preferred Stock or by law, the holders of Series A Preferred Shares and the holders of shares of Common Stock and any other capital stock of the Corporation having general voting rights shall vote together as one class on all matters submitted to a vote of the stockholders of the Corporation.

(iii) Except as otherwise provided herein or by law, the holders of Series A Preferred Shares shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of shares of Common Stock and any other capital stock of the Corporation having general voting rights as set forth herein) for taking any corporate action.

4. Certain Restrictions.

(i) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Shares as provided in paragraph 2 hereof are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on Series A Preferred Shares outstanding shall have been paid in full, the Corporation shall not:

(a) declare or pay dividends, or make any other distributions, on any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares;

(b) declare or pay dividends, 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 Shares, except dividends paid ratably on the Series A Preferred Shares 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;

(c) redeem or purchase or otherwise acquire for consideration shares of any stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such junior stock in exchange for shares of stock of the Corporation ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares; or

(d) redeem or purchase or otherwise acquire for consideration any Series A Preferred Shares, or any shares of stock ranking on a parity with the Series A Preferred

A-3

Shares, 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.

(ii) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under subparagraph (i) of this paragraph 4, purchase or otherwise acquire such shares at such time and in such manner.

5. Reacquired Shares. Any Series A Preferred Shares purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. The Corporation shall take all such actions as are necessary to cause all such shares to become authorized but unissued shares of Preferred Stock that may be reissued as part of a new series of Preferred Stock, subject to the conditions and restrictions on issuance set forth herein or in the Certificate of Incorporation, including any Certificate of Designations creating a series of Preferred Stock or any similar stock, or as otherwise required by law.

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 Shares unless, prior thereto, the holders of Series A Preferred Shares shall have received the greater of (i) $1.00 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, or (ii) an aggregate amount per share, subject to the provision for adjustment hereinafter set forth, equal to one hundred (100) times the aggregate amount to be distributed per share to holders 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 Shares, except distributions made ratably on the Series A Preferred Shares 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. If the Corporation shall at any time after August 8, 2005 declare or pay any dividend on the shares of Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding Common Stock (by reclassification or otherwise) into a greater or lesser number of shares of Common Stock, then in each such case the aggregate amount to which holders of Series A Preferred Shares were entitled immediately before such event under clause (a)(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 outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately before such event.

7. Consolidation, Merger, Exchange, etc. If the Corporation shall enter into any consolidation, merger, combination, or other transaction in which the Common Shares are exchanged for or changed into other stock or securities, money and/or any other property, then in any such case the Series A Preferred Shares shall at the same time be similarly exchanged or changed into an amount per share (subject to the provision for adjustment hereinafter set forth)

A-4

equal to one hundred (100) times the aggregate amount of stock, securities, money 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. If the Corporation shall at any time after August 8, 2005 declare or pay any dividend on shares of 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 on shares of Common Stock payable in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of Series A Preferred Shares 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 before such event.

8. Amendment. The Certificate of Incorporation shall not be amended in any manner, including in a merger or consolidation, which would alter, change, or repeal the powers, preferences or special rights of the Series A Preferred Shares so as to affect them adversely without the affirmative vote of the holders of at least two thirds of the outstanding Series A Preferred Shares, voting together as a single class.

9. No Redemption. The Series A Preferred Shares shall not be redeemable.

10. Rank. The Series A Preferred Shares shall rank junior with respect to the payment of dividends and distribution of assets upon liquidation, dissolution or winding up to all other series of the Corporation’s Preferred Stock hereafter issued that specifically provide that they shall rank senior to the Series A Preferred Shares.

11. Fractional Shares. Series A Preferred Shares may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Preferred Shares.

IN WITNESS WHEREOF, this Certificate of Designations is executed on behalf of the Corporation by its                                 , all as of the 8th day of August, 2005.

EXHIBIT C

SUMMARY OF RIGHTS TO PURCHASE

PREFERRED SHARES

On July 26, 2005, the Board of Directors of Entegris, Inc., then known as Eagle DE, Inc., (the “Company”) declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of Common Stock, par value $0.01 per share (the “Common Shares”) outstanding on August 8, 2005 (the “Record Date”) to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one-hundredth of a share of Series A Junior Participating Preferred Capital Stock, $0.01 par value per share, of the Company (the “Preferred Shares”), at a price of $50.00 per one-hundredth of a Preferred Share (the “Purchase Price”), subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement (the “Rights Agreement”) between the Company and Xxxxx Fargo Bank, N.A., as Rights Agent (the “Rights Agent”).

Initially, the Rights will attach to all certificates representing Common Shares then outstanding and no separate Right Certificates will be distributed. The Rights will separate from the Common Shares and a Distribution Date for the Rights will occur, subject to certain exceptions, upon the latest to occur of:

(A)(i) ten business days following a public announcement that a person or group of affiliated or associated persons has become an “Acquiring Person” (i.e., has become, subject to certain exceptions, the beneficial owner of 15% or more of the outstanding Common Shares), or (ii) ten business days (or such later date as may be determined by action of the Board of Directors prior to such time as any Person becomes an Acquiring Person) following the commencement of, or first public announcement of the making of, or intention to make, a tender offer or exchange offer the consummation of which would result in a person or group of affiliated or associated persons becoming, subject to certain exceptions, the beneficial owner of 15% or more of the outstanding Common Shares, whichever is earlier;

(B) such date or the occurrence of such event thereafter which is on or after the Record Date, as may be determined by action of the Board of Directors prior to the Distribution Date as determined by the earlier of (A)(i) or (A)(ii), or

(C) such date or the occurrence of such event thereafter as may be determined by action of the Board of Directors from time to time prior to the date or the occurrence of such event on which the Distribution Date would have occurred, but for the most recent determination by the Board of Directors.

Until the Distribution Date, the Rights will be evidenced by the Common Share certificates and transferred with and only with the Common Shares, new Common Share certificates issued after the Record Date or upon transfer or new issuance of Common Shares will contain a notation incorporating the Rights Agreement by reference and the surrender for transfer of any certificates for Common Shares, even without such notation or a copy of this Summary of Rights being attached thereto, 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 August 8, 2015 (the “Final Expiration Date”), unless the Final Expiration Date is extended or 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 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 periodic cash dividends paid out of earnings or retained earnings or dividends payable in Preferred Shares) or of subscription rights or warrants (other than those referred to above). The number of Preferred Shares issuable upon the exercise of a Right is also subject to adjustment in the event of a dividend on Common Shares payable in Common Shares, or a subdivision, combination or consolidation of the Common Shares.

If any person or group of affiliated or associated persons becomes an Acquiring Person, proper provisions shall be made so that each holder of a Right, other than Rights that are or were beneficially owned by the Acquiring Person (which will thereafter be void), will thereafter have the right to receive upon exercise of the Right at the then current exercise price of the Right that number of Common Shares having a market value of two times the exercise price of the Right, subject to certain possible adjustments.

In the event that, at any time after a Person becomes an Acquiring Person, the Company is acquired in a merger or other business combination transaction or 50% or more of its consolidated assets or earning power are sold, proper provision will be made so that each holder of a Right will thereafter have the right to receive, upon the exercise thereof at the then current exercise price of the Right, 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 exercise price of the Right.

At any time after a person or group of affiliated or associated persons becomes an Acquiring Person (subject to certain exceptions) and prior to the acquisition by any person or group of 50% or more of the outstanding Common Shares, the Board of Directors of the Company may exchange all or part of the Rights (other than Rights owned by such person or group which have become void) for Common Shares or equivalent securities at an exchange ratio per Right equal to the result obtained by dividing the exercise price of a Right by the current per share market price of the Common Shares, subject to adjustment.

- C-2 -

At any time prior to the time any person or group of affiliated or associated persons becomes an Acquiring Person, the Board of Directors of the Company may redeem the Rights in whole, but not in part, at a price of $0.01 per Right, subject to adjustment (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.

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, except that from and after the Distribution Date and from and after such time as any person becomes an Acquiring Person no such amendment may adversely affect the interests of the holders of the Rights (other than the Acquiring Person and its affiliates and associates).

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

A copy of the Agreement has been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A dated August 8, 2005. A copy of the Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Agreement, which is hereby incorporated herein by reference.
