This STOCKHOLDERS RIGHTS AGREEMENT, dated as of June 2, 2008 (the “Effective Date”) by and between MarketAxess Holdings Inc., a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC a New York limited liability trust company (the “Rights Agent”).

WHEREAS, effective June 2, 2008 (the “Rights Dividend Declaration Date”), the Board of Directors of the Company authorized and declared a distribution of one right for each share of common stock, par value $0.003 per share, of the Company (the “Common Stock”) and each share of nonvoting common stock, par value $0.003 per share, of the Company (the “Nonvoting Common Stock”) outstanding at the Close of Business (as such term is defined herein) on June 20, 2008 (the “Record Date”), and has authorized the issuance of one such right (as such number may hereafter be adjusted pursuant hereto) for each Common Share that shall become outstanding (whether originally issued or delivered from the Company’s treasury) between the Record Date and, except as otherwise provided in Section 22 herein, the Distribution Date, each such right initially representing the right to purchase, upon the terms and subject to the conditions hereinafter set forth, one Unit of Series A Preferred Stock (each a “Right” and together with all other such rights distributed or issued pursuant hereto, the “Rights”).

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

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

(a) “Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of shares of Voting Stock representing 20% or more of the total Voting Power of the aggregate of all shares of Voting Stock then outstanding, but shall not include the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any trustee or fiduciary holding Voting Stock for, or pursuant to the terms of, any such plan, acting in such capacity. Notwithstanding the foregoing:

(i) No Person shall become an “Acquiring Person” as the result of an acquisition of Voting Stock by the Company, which, by reducing the number of shares of Voting Stock outstanding, increases the proportionate percentage of the total Voting Power represented by all shares of Voting Stock Beneficially Owned by such Person, together with all Affiliates and Associates of such Person, to 20% or more of the total Voting Power of the aggregate of all shares of Voting Stock then outstanding; provided, however, that if a Person, together with all Affiliates and Associates of such Person, shall become the Beneficial Owner of shares of Voting Stock representing 20% or more of total Voting Power of the aggregate of all shares of Voting Stock then outstanding by reason of share purchases by the Company and shall, after such share purchases by the Company, become the Beneficial Owner of any additional shares of Voting Stock (other than shares issued by the Company as a dividend or distribution made pro rata to all holders of Common Shares), then, subject to Section 1(a)(ii), such Person shall be deemed to be an “Acquiring Person;”

(ii) If the Board of Directors determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to this Section 1(a), has become such inadvertently, and such Person divests as promptly as practicable a sufficient number of shares of Voting Stock so that such Person would no longer be an “Acquiring Person,” as defined pursuant to this Section 1(a), then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement; and

(iii) If a Person would otherwise be deemed an “Acquiring Person” upon the adoption of this Agreement, such Person (herein referred to as a “Grandfathered Stockholder”) will not be deemed an “Acquiring Person” for purposes of this Agreement unless and until, subject to Section 1(a)(ii), such Grandfathered Stockholder, or any Affiliate or Associate of such Grandfathered Stockholder, acquires Beneficial Ownership of additional shares of Voting Stock after adoption of this Agreement in excess of one percent (1%) of the number of shares of Common Stock outstanding as of the Rights Dividend Declaration Date, in which case, such Person shall no longer be deemed a Grandfathered Stockholder and shall be deemed an “Acquiring Person”; and

(iv) TCV shall not be an “Acquiring Person” pursuant to this Section 1(a) for so long as TCV shall be the Beneficial Owner of shares of Voting Stock and Nonvoting Common Stock representing, in the aggregate, less than 19.9% of the sum of (x) the total Voting Power of the aggregate of all shares of Voting Stock then outstanding plus (y) the total Voting Power of the aggregate of all shares of Voting Stock into which all outstanding shares of Nonvoting Common Stock are then convertible, plus (z) the total Voting Power of the aggregate of all shares of Voting Stock issuable upon exercise of warrants to purchase Common Stock issued by the Company to TCV.

(b) “Affiliate” and “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the Exchange Act Regulations, as in effect on the date of this Agreement; provided, however, that no director or officer of the Company shall be deemed an Affiliate or Associate of any other director or officer of the Company solely as a result of his or her being a director or officer of the Company.

(ii) that such Person or any of such Person’s Affiliates or Associates has (A) the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement, or understanding, whether or not in writing (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), or upon the exercise of conversion rights, exchange rights, rights (other than these Rights), warrants, or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to Beneficially Own or to have Beneficial Ownership of securities tendered pursuant to a tender or exchange offer made in accordance with the

Exchange Act Regulations by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange; or (B) the right to vote pursuant to any agreement, arrangement, or understanding (except to the extent contemplated by the proviso to subparagraph (i) of this paragraph (c)); or

(iii) that are Beneficially Owned, directly or indirectly, by any other Person (or any Affiliate or Associate of such Person) with which such Person (or any of such Person’s Affiliates or Associates) has any agreement, arrangement, or understanding, whether or not in writing (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities) for the purpose of acquiring, holding, voting (except to the extent contemplated by the proviso to subparagraph (i) of this paragraph (c)), or disposing of any such securities.

(x)

the Rights will be evidenced (subject to the provisions of paragraph (b) of this Section 3) by the certificates for shares of Common Stock or Nonvoting Common Stock, as applicable, registered in the names of the holders of shares of Common Stock or Nonvoting Common Stock, as applicable, as of and subsequent to the Record Date (which certificates for shares of Common Stock shall be deemed also to be certificates for Rights) and not by separate rights certificates; and

(y)

the Rights will be transferable only in connection with the transfer of the underlying shares of Common Stock or Nonvoting Common Stock, as applicable (including a transfer to the Company).

As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign, and the Company will send or cause to be sent (and the Rights Agent, if so requested, will 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 rights certificates, in substantially the form of Exhibit A (the “Rights Certificates”), evidencing one Right for each Common Share so held, subject to adjustment as provided herein. In the event that an adjustment in the number of Rights per Common Share has been made pursuant to Section 11(i) or Section 11(p) hereof, at the time of distribution of the Rights Certificates, the Company may make the necessary and appropriate rounding adjustments (in accordance with Section 14(a) hereof) so that Rights Certificates representing only whole numbers of Rights are distributed and cash is paid in lieu of any fractional Rights. As of and after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates.

(b) As promptly as practicable following the Record Date, the Company will send a copy of a Summary of Rights to Purchase Series A Preferred Stock in substantially the form attached hereto as Exhibit B and which may be appended to certificates that represent Common Shares (hereinafter referred to as 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 Distribution Date, the Rights will be evidenced by such certificates registered in the names of the holders thereof together with a copy of the Summary of Rights attached thereto. Until the earlier of the Distribution Date or the Expiration Date, the surrender for transfer of any certificate for Common Shares outstanding on the Record Date, with or without a copy of the Summary of Rights attached thereto, shall also constitute the transfer of the Rights associated with the Common Shares represented thereby.

(c) Rights shall, without any further action, be issued in respect of all Common Shares that become outstanding (whether originally issued or delivered from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date; provided, that with respect to any shares of Common Stock issued upon conversion of shares of Nonvoting Common Stock, no additional Rights shall be issued, but the Rights attached to such shares of Nonvoting Common Stock shall be attached to such shares of Common Stock after such conversion. Certificates, representing such Common Shares, issued after the Record Date shall bear the following legend:

“This certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Stockholders Rights Agreement between MarketAxess Holdings Inc. (the “Company”) and American Stock Transfer & Trust Company, LLC (the “Rights Agent”) dated as of June 2, 2008 (the “Rights Agreement”), the terms of which are incorporated herein by reference and a copy of which is on file at the principal office 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, as in effect on the date of mailing, without charge after receipt of a written request therefor. Under certain circumstances, as set forth in the Rights Agreement, Rights that are Beneficially Owned by any Person who is, was, or becomes an Acquiring Person or any Affiliate or Associate thereof (as such capitalized terms are defined in the Rights Agreement), or specified transferees of such Acquiring Person (or Affiliate or Associate thereof) may become null and void.”

After the Record Date but prior to the earlier of the Distribution Date and the Expiration Date, if new certificate(s) representing Common Shares are issued in connection with the transfer, split up, combination, or exchange of certificate(s) representing Common Shares or if new certificate(s) representing Common Shares are issued to replace any certificate(s) that have been mutilated, destroyed, lost, or stolen, then such new certificate(s) shall bear the foregoing legend. With respect to all certificates containing the foregoing legend, until the earlier of the Distribution Date or the Expiration Date, the Rights associated with the Common Shares represented by such certificates shall be evidenced by such certificates alone and registered holders of the Common Shares shall also be the registered holders of the associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Shares represented by such certificates. In the event that the Company purchases or acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares shall be deemed cancelled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Shares that are no longer outstanding.

Section 4. Form of Rights Certificate. (a) The Rights Certificates (and the forms of election to purchase and of assignment and the certificate to be printed on the reverse thereof) shall be substantially in the form set forth in Exhibit A hereto and may have such marks of identification or designation and such legends, summaries, or endorsements printed thereon as the Company may deem appropriate (but which do not affect the rights, duties, or responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or any rule or regulation thereunder or with any rule or regulation of any stock exchange upon which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Sections 7, 11, 13, 22, 23, 24, and 27 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Distribution Date and on their face shall entitle the holders thereof to purchase such number of Units of Series A Preferred Stock as shall be set forth therein at the price set forth therein, but the amount and type of securities, cash, or other assets that may be acquired upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein.

(b) Any Rights Certificate issued pursuant hereto that represents Rights Beneficially Owned by: (i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) that becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person

(or of any such Associate or Affiliate) that becomes a transferee prior to or concurrently with the Acquiring Person becoming such and that receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person (or any such Associate or Affiliate) to holders of equity interests in such Acquiring Person (or such Associate or Affiliate) or to any Person with whom such Acquiring Person (or such Associate or Affiliate) has any continuing written or oral agreement, arrangement, or understanding regarding either the transferred Rights, Common Shares, or the Company, or (B) a transfer that the Board of Directors has determined in good faith to be part of a plan, agreement, arrangement, or understanding that has as a primary purpose or effect the avoidance of Section 7(e) hereof shall, upon the written direction of the Board of Directors, contain (to the extent feasible), the following legend:

“The Rights represented by this Rights Certificate are or were Beneficially Owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such capitalized terms are defined in the Stockholders Rights Agreement, dated as of June 2, 2008 (the “Rights Agreement”), by and between MarketAxess Holdings Inc. and American Stock Transfer & Trust Company, LLC, as Rights Agent). Accordingly, this Rights Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 7(e) of the Rights Agreement.”

Section 5. Countersignature and Registration. (a) Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, its Vice Chairman of the Board, or its Treasurer, shall have affixed thereto the Company’s corporate seal (or a facsimile thereof), and shall be attested by the Company’s Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Rights Certificates may be manual or by facsimile. Rights Certificates bearing the manual or facsimile signatures of the individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersigning of such Rights Certificates by the Rights Agent or did not hold such offices at the date of such Rights Certificates. No Rights Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose unless there appears on such Rights Certificate a countersignature duly executed by the Rights Agent by manual or facsimile signature of an authorized officer, and such countersignature upon any Rights Certificate shall be conclusive evidence, and the only evidence, that such Rights Certificate has been duly countersigned as required hereunder.

(b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its office designated for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the name and address of each holder of the Rights Certificates, the number of Rights evidenced on its face by each Rights Certificate, and the date of each Rights Certificate.

Section 6. Transfer, Split Up, Combination, and Exchange of Rights Certificates; Mutilated, Destroyed, Lost, or Stolen Rights Certificates. (a) Subject to the provisions of Sections 4(b), 7(e), and 14 hereof, at any time after the Close of Business on the Distribution

Date, and at or prior to the Close of Business on the Expiration Date, any Rights Certificate or Certificates (other than Rights Certificates representing Rights that have become null and void pursuant to Section 7(e) hereof, that have been redeemed pursuant to Section 23 hereof, or that have been exchanged pursuant to Section 24 hereof) may be transferred, split up, combined, or exchanged for another Rights Certificate or Certificates, entitling the registered holder to purchase a like number of Units of Series A Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) as the Rights Certificate or Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up, combine, or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Certificates to be transferred, split up, combined, or exchanged at the office of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Rights Certificate until the registered holder shall have completed and executed the certificate set forth in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) of the Rights represented by such Rights Certificate or Affiliates or Associates thereof as the Company shall reasonably request; whereupon the Rights Agent shall, subject to the provisions of Section 4(b), Section 7(e) and Section 14 hereof, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination, or exchange of Rights Certificates.

(b) If a Rights Certificate shall be mutilated, lost, stolen, or destroyed, upon request by the registered holder of the Rights represented thereby and upon payment to the Company and the Rights Agent of all reasonable expenses incident thereto, there shall be issued, in exchange for and upon cancellation of the mutilated Rights Certificate, or in substitution for the lost, stolen, or destroyed Rights Certificate, a new Rights Certificate, in substantially the form of the prior Rights Certificate, of like tenor and representing the equivalent number of Rights, but, in the case of loss, theft, or destruction, only upon receipt of evidence satisfactory to the Company and the Rights Agent of such loss, theft or destruction of such Rights Certificate and, if requested by the Company or the Rights Agent, indemnity also satisfactory to it.

Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights. (a) Prior to the earlier of (i) the Close of Business on June 2, 2011 (the “Final Expiration Date”), or (ii) the time at which the Rights are redeemed as provided in Section 23 hereof or (iii) the time at which the Rights are exchanged as provided in Section 24 hereof (the earlier of (i), (ii), and (iii) being the “Expiration Date”), the registered holder of any Rights Certificate may, subject to the provisions of Sections 7(e), 9(c), and 9(f) hereof, exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date upon surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price (as hereinafter defined) for the number of Units of Series A Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) for which such surrendered Rights are then exercisable.

(b) The purchase price for each one one-thousandth of a share of Series A Preferred Stock purchasable upon exercise of a Right shall be $40.00 (as adjusted from time to time as provided in Sections 11 and 13(a) hereof) (the “Purchase Price”). The Purchase Price shall be subject to adjustment from time to time as provided in Sections 11 and 13(a) hereof and shall be payable in lawful money of the United States of America in accordance with paragraph (c)(2) below. Each one one-thousandth of a share of Series A Preferred Stock shall be referred to herein as a “Unit” of Series A Preferred Stock.

(c) (i) Subject to Section 14(b) hereof, following the Distribution Date, the Company may (at the direction of the Board of Directors) deposit with a corporation in good standing organized under the laws of the United States or any State of the United States, which is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by federal or state authority (the “Depositary Agent”) certificates representing the shares of Series A Preferred Stock that may be acquired upon exercise of the Rights and may cause such Depositary Agent to enter into an agreement pursuant to which the Depositary Agent shall issue receipts representing interests in the shares of Series A Preferred Stock so deposited.

(ii) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase and the certificate duly executed, accompanied by payment, with respect to each Right so exercised, of the Purchase Price for the Units of Series A Preferred Stock (or, following a Triggering Event, other securities, cash, or other assets, as the case may be) to be purchased thereby as set forth below and an amount equal to any applicable tax or charge required to be paid by the holder of such Rights Certificate in accordance with Section 9 hereof, or evidence satisfactory to the Company of payment of such tax or charge, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly (i)(A) requisition from any transfer agent of the Series A Preferred Stock certificates representing such number of shares of Series A Preferred Stock (or fractions of shares that are integral multiples of one one-thousandth of a share of Series A Preferred Stock) as are to be purchased and the Company will direct its transfer agent to comply with all such requests, and/or (B) requisition from the Depositary Agent depositary receipts representing such number of Units of Series A Preferred Stock as are to be purchased and the Company will direct the Depositary Agent to comply with all such requests, (ii) requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or such depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate. In the event that the Company is obligated to issue Common Shares or other securities of the Company, pay cash, and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such Common Shares, other securities, cash, and/or other property is available for distribution by the Rights Agent, if and when necessary to comply with this Agreement. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii) hereof) may be made in cash or by certified or bank check or money order payable to the order of the Company.

(d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate evidencing the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Sections 6 and 14 hereof.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the time that any Person becomes an Acquiring Person, any Rights Beneficially Owned by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and who receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person (or any such Associate or Affiliate) to holders of equity interests in such Acquiring Person (or any such Associate or Affiliate) or to any Person with whom the Acquiring Person (or such Associate or Affiliate) has any continuing written or oral agreement, arrangement, or understanding regarding the transferred Rights, Common Shares, or the Company or (B) a transfer that the Board of Directors has determined in good faith to be part of a plan, agreement, arrangement, or understanding that has as a primary purpose or effect the avoidance of this Section 7(e), shall be null and void without any further action, and any holder of such Rights thereafter shall have no rights or preferences whatsoever with respect to such Rights, whether under any provision of this Agreement, the Rights Certificates, or otherwise (including, without limitation, rights and preferences pursuant to Sections 7, 11, 13, 23, and 24 hereof). The Company shall use reasonable efforts to ensure compliance with the provisions of this Section 7(e) and Section 4(b), but neither the Company nor the Rights Agent shall have any liability to any holder of Rights or any other Person as a result of the Company’s failure to make any determination under this Section 7(e) or such Section 4(b) with respect to an Acquiring Person or its Affiliates, Associates, or transferees.

(f) Notwithstanding anything in this Agreement or any Rights Certificate 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 by such registered holder unless such registered holder shall have (i) completed and executed the certificate following the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) of the Rights represented by such Rights Certificate or Affiliates or Associates thereof as the Company shall reasonably request.

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

Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. Reservation and Availability of Capital Stock. (a) The Company shall at all times prior to the Expiration Date cause to be reserved and kept available out of its authorized but unissued shares of Series A Preferred Stock and/or out of any shares of Series A Preferred Stock held in its treasury (and following the occurrence of a Triggering Event, out of the authorized but unissued shares of such other equity securities of the Company as may be issuable upon exercise of the Rights and/or out of any shares of such securities held in its treasury), the number of shares of Series A Preferred Stock (and following the occurrence of a Triggering Event, the number of shares of such other equity securities of the Company) that, as provided in this Agreement, will be sufficient to permit the full exercise of all outstanding Rights. Upon the occurrence of any events resulting in an increase in the aggregate number of shares of Series A Preferred Stock (or other equity securities of the Company) issuable upon exercise of all outstanding Rights above the number then reserved, the Company shall make appropriate increases in the number of shares so reserved.

(b) So long as the shares of Series A Preferred Stock (and following the occurrence of a Triggering Event, any other equity securities of the Company) to be issued and delivered upon the exercise of the Rights may be listed on any stock exchange, the Company shall during the period from the Distribution Date through the Expiration Date use its best efforts to cause all securities reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise.

(c) The Company shall use its reasonable best efforts (i) either (A) as soon as practicable following the first occurrence of a Section 11(a)(ii) Event and a determination by the Company in accordance with Section 11(a)(iii) hereof, if applicable, of the consideration to be delivered by the Company upon exercise of the Rights, or (B) if so required by law, as soon as required following the Distribution Date (the earliest of (A) and (B) being the “Registration Date”), to file a registration statement on an appropriate form under the Securities Act, with respect to the securities that may be acquired upon exercise of the Rights (the “Registration Statement”); (ii) to cause the Registration Statement to become effective as soon as practicable after such filing; (iii) to cause the Registration Statement to remain effective (and to include a prospectus at all times complying with the requirements of the Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for the securities covered by the Registration Statement and (B) the Expiration Date; and (iv) to take as soon as practicable following the Registration Date such action as may be required to ensure that any acquisition of securities upon exercise of the Rights complies with any applicable state securities or “Blue Sky” laws. The Company may temporarily suspend, for a period of time not to exceed 90 days after the date set forth in clause (i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Company shall notify the Rights Agent thereof in writing and shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement (with written notice thereof to the Rights Agent) at such time as the suspension is no longer in effect, stating that the suspension on the exercisability of the Rights is no longer in effect. Notwithstanding any provision of this

Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction (x) if the requisite qualification in such jurisdiction shall not have been obtained and until a registration statement has been declared effective or (y) if the exercise thereof shall not be permitted under applicable law.

(d) The Company shall take such action as may be necessary to ensure that all shares of Series A Preferred Stock (and, following the occurrence of a Triggering Event, any other securities that may be delivered upon exercise of Rights) shall be, at the time of delivery of the certificates or depositary receipts for such securities (subject to payment of the Purchase Price), duly and validly authorized and issued, fully paid and non-assessable.

(e) The Company shall pay when due and payable any and all documentary, stamp, or transfer tax, or other tax or charge, that is payable in respect of the issuance and delivery of the Rights Certificates or the issuance and delivery of any certificates or depository receipts for Series A Preferred Stock (or other equity securities of the Company that may be delivered upon exercise of the Rights) upon the exercise of Rights; provided, however, that the Company shall not be required to pay any such tax or charge that may be payable in connection with the issuance or delivery of Units of Series A Preferred Stock, or any certificates or depositary receipts for such Units of Series A Preferred Stock (or, following the occurrence of a Triggering Event, any other securities, cash or other assets, as the case may be) to any Person other than the registered holder of the Rights Certificates evidencing the Rights surrendered for exercise. The Company shall not be required to issue or deliver any certificates or depositary receipts for Units of Series A Preferred Stock (or, following the occurrence of a Triggering Event, any other securities, cash or other assets, as the case may be) to, or in a name other than that of, the registered holder upon the exercise of any Rights until any such tax or charge shall have been paid (any such tax or charge being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax or charge is due.

(f) The Company shall use its reasonable best efforts, on or prior to the date that is either (A) as soon as practicable following the first occurrence of a Section 11(a)(ii) Event and a determination by the Company in accordance with Section 11(a)(iii) hereof, if applicable, of the consideration to be delivered by the Company upon exercise of the Rights, or (B) if so required by law, as soon as required following the Distribution Date, to obtain any and all regulatory approvals that may be required with respect to the securities purchasable upon exercise of the Rights. The Company may temporarily suspend, for a period of time not to exceed 90 days after the date set forth in the first sentence of this Section 9(f), the exercise of the Rights in order to permit the Company to obtain the necessary regulatory approvals. Upon any such suspension, the Company shall notify the Rights Agent thereof in writing and issue a public announcement stating that the exercise of the Rights has been temporarily suspended, as well as a public announcement (with written notice thereof to the Rights Agent) at such time as the suspension is no longer in effect stating that the suspension on the exercise of the Rights is no longer in effect. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable unless and until all required regulatory approvals have been obtained with respect to the securities purchasable upon exercise of the Rights.

Section 10. Series A Preferred Stock Record Date. Each Person in whose name any certificate for Units of Series A Preferred Stock (or, following the occurrence of a Triggering Event, other securities) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Units of Series A Preferred Stock (or, following the occurrence of a Triggering Event, other securities) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and any applicable transfer taxes) was made; provided, however, that if the date of such surrender and payment is a date upon which the Series A Preferred Stock (or, following the occurrence of a Triggering Event, other securities) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such securities on, and such certificate shall be dated, the next succeeding Business Day on which the Series A Preferred Stock (or, following the occurrence of a Triggering Event, other securities) transfer books of the Company are open and, provided further, that if delivery of Units of Series A Preferred Stock is delayed pursuant to Section 9(c) hereof, such Persons shall be deemed to have become the record holders of such Units of Series A Preferred Stock only when such Units first become deliverable. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate shall not be entitled to any rights of a shareholder of the Company with respect to securities 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 securities covered by each Right, and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

(a) (i) In the event the Company shall at any time after the Rights Dividend Declaration Date (A) declare a dividend on the Series A Preferred Stock payable in shares of Series A Preferred Stock, (B) subdivide the outstanding Series A Preferred Stock, (C) combine the outstanding Series A Preferred Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a reclassification of the Series A Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a), the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares (or fractions thereof) of Series A Preferred Stock or capital stock, as the case may be, issuable on such date upon 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, the aggregate number and kind of shares (or fractions thereof) of Series A Preferred Stock or capital stock, as the case may be, which, 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 (or fractions thereof) of capital stock of the Company issuable upon exercise of one Right. If an event occurs that would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided

for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

(ii) In the event any Person becomes an Acquiring Person, provision shall be made so that each holder of a Right (except as provided below in Section 11(a)(iii) and in Sections 7(e), 13, and 24 hereof) shall thereafter have the right to receive, upon exercise thereof, at a price equal to the then current Purchase Price multiplied by the number of Units of Series A Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event (such product thereafter being, for all purposes of this Agreement other than Section 13 hereof, the “Purchase Price”), in accordance with the terms of this Agreement, in lieu of the number of Units of Series A Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event, such number of shares of Common Stock as shall equal the result obtained by dividing (x) the Purchase Price (as the same has been adjusted pursuant to the foregoing provisions of this Section 11(a)(ii)), by (y) 50% of the then current market price (determined pursuant to Section 11(d) hereof) per share of Common Stock on the date of such first occurrence (such shares of Common Stock being the “Adjustment Shares”).

(iii) In the event that the number of shares of Common Stock that are authorized by the Company’s Certificate of Incorporation but are not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is insufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exercise of the Rights. In the event that the Company shall, after good faith effort, be unable to take all such actions as may be necessary to authorize such additional shares of Common Stock, then the Company shall issue Common Stock to the extent shares thereof are available in connection with exercise of the Rights and to the extent sufficient shares of Common Stock are not available therefor shall substitute, for each share of Common Stock that would otherwise be issuable upon exercise of a Right, a number of Units of Series A Preferred Shares such that the current per share market price of one Unit of Series A Preferred Stock multiplied by such number of Units is equal (as nearly as possible) to the current per share market price of one share of Common Stock as of the date of issuance of such Units of Series A Preferred Stock. In the event that the number of shares of Common Stock, together with the number of Units of Series A Preferred Stock, that are authorized by the Company’s Certificate of Incorporation but are not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is insufficient to permit the exercise in full of the Rights in accordance with the foregoing provisions of this subparagraph (iii) and subparagraph (ii) of this Section 11(a), then the Company shall take all such action as may be necessary to authorize additional shares of Series A Preferred Stock for issuance upon exercise of the Rights. In the event that the Company shall, after good faith effort, be unable to take all such actions as may be necessary to authorize such additional shares of Common Stock and/or Units of Series A Preferred Stock, then the Company, by the vote of a majority of the Board of Directors, shall: (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of each such Right (the “Current Value”) over (2) the Purchase Price (such excess being

the “Spread”), and (B) with respect to each such Right, make adequate provision to substitute for such Adjustment Shares, upon exercise of such Rights and payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common Stock, Units of Series A Preferred Stock, and/or other equity securities of the Company, each to the extent permitted by the Company’s Certificate of Incorporation (including, without limitation, shares, or units of shares, of preferred stock that the Board of Directors has deemed to have the same value as shares of Common Stock (the “Preferred Stock Equivalents”)), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate value equal to the Current Value, where such aggregate value has been determined by a majority of the Board of Directors, after receiving advice from a nationally recognized investment banking firm; provided, however, that if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty days following the first occurrence of a Section 11(a)(ii) Event (for purposes hereof, the “Section 11(a)(iii) Trigger Date”), then the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, shares of Common Stock (to the extent available) and then, if necessary, Units of Series A Preferred Stock (to the extent available) and then, if necessary, cash, which shares of Common Stock, Units of Series A Preferred Stock and/or cash shall have an aggregate value equal to the Spread. To the extent that the Company determines that some action need be taken pursuant to this Section 11(a)(iii), the Company shall provide, subject to Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights. For purposes of this Section 11(a)(iii), the value of a share of Common Stock shall be the current market price (as determined pursuant to Section 11(d) hereof) per share of Common Stock on the Section 11(a)(iii) Trigger Date, the value of a Unit of Series A Preferred Stock shall be the current market price (as determined pursuant to Section 11(d) hereof) per Unit of Series A Preferred Stock on the Section 11(a)(iii) Trigger Date, and the value of a unit or share, as applicable, of any Preferred Stock Equivalent shall be deemed to have the same value as the Common Stock on such date.

(b) In case the Company shall fix a record date for the issuance of rights, options, or warrants to all holders of any Series A Preferred Stock entitling them to subscribe for or purchase (for a period expiring within forty-five calendar days after such record date) shares of Series A Preferred Stock (or shares having substantially the same rights, privileges, and preferences as shares of Series A Preferred Stock (“Equivalent Preferred Stock”)) or securities convertible into Series A Preferred Stock or Equivalent Preferred Stock at a price per share of Series A Preferred Stock or per share of Equivalent Preferred Stock (or having a conversion price per share, if a security convertible into Series A Preferred Stock or Equivalent Preferred Stock) less than the current market price (as determined pursuant to Section 11(d) hereof) per share of Series A Preferred Stock on such record date, then the Purchase Price with respect to the Series A Preferred Stock 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 sum of the number of shares of Series A Preferred Stock outstanding on such record date plus the number of shares of Series A Preferred Stock that the aggregate offering price of the total number of shares of Series A Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price, and the denominator of which shall be

the number of shares of Series A Preferred Stock outstanding on such record date plus the number of additional shares of Series A Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid by delivery of consideration all or part of which may be in a form other than cash, the value of such consideration shall be as determined by the Board of Directors, 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. Shares of Series A Preferred Stock owned by or held for the account of the Company or any Subsidiary shall not be deemed outstanding for the purpose of such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights 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 a distribution to all holders of shares of Series A Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation), evidences of indebtedness, cash (other than a regular quarterly cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in shares of Series A Preferred Stock, but including any dividend payable in stock other than Series A Preferred Stock), or subscription rights, options, or warrants (excluding those referred to in Section 11(b) hereof), then, in each case, 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 current market price (as determined pursuant to Section 11(d) hereof) per share of Series A Preferred Stock on such record date minus the fair market value (as determined in good faith by a majority of the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding and conclusive for all purposes on the Rights Agent and the holder of the Rights) of the cash, assets, or evidences of indebtedness so to be distributed or of such subscription rights or warrants distributable in respect of a share of Series A Preferred Stock and the denominator of which shall be such current market price (as determined pursuant to Section 11(d) hereof) per share of Series A Preferred Stock on such record date. 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 be adjusted to be the Purchase Price that would have been in effect if such record date had not been fixed.

(d) (i) For the purpose of any computation hereunder, the “current market price” per share of any security, including the Common Stock or any Common Equity Interest, on any date shall be deemed to be the average of the daily closing prices per share of such security for the ten consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, if prior to the expiration of such requisite ten Trading Day period, the issuer announces either (A) a dividend or distribution on such security payable in shares of such security or securities convertible into such shares (other than the Rights), or (B) any subdivision, combination, or reclassification of such shares, then, following the ex-dividend date for such dividend or the record date for such subdivision, as the case may be, the “current market price” for such security shall be properly adjusted to take into account such event. The closing price for each day shall be, if the shares of such security are listed and admitted to trading on a national securities exchange, as reported in the principal consolidated transaction reporting system with

respect to securities listed on the principal national securities exchange on which such shares of such security are listed or admitted to trading or, if such shares are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotation System (“NASDAQ”) or such other system then in use, or, if on any such date such shares are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in such shares selected by a majority of the Board of Directors. If on any such date no market maker is making a market in such shares, the fair value of such shares on such date as determined in good faith by a majority of the Board of Directors shall be used. If such shares are not publicly held or not so listed or traded, “current market price” per share shall mean the fair value per share as determined in good faith by a majority of the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. The term “Trading Day” shall mean, if such shares of such security are listed or admitted to trading on any national securities exchange, a day on which the principal national securities exchange on which such shares are listed or admitted to trading is open for the transaction of business or, if such shares are not so listed or admitted, a Business Day.

(ii) For the purpose of any computation hereunder, the “current market price” per share of Series A Preferred Stock shall be determined in the same manner as set forth above for Common Stock in clause (i) of this Section 11(d) (other than the fourth sentence thereof). If the current market price per share of Series A Preferred Stock cannot be determined in the manner provided above or if the Series A Preferred Stock is not publicly held or listed or traded in a manner described in clause (i) of this Section 11(d), the “current market price” per share of Series A Preferred Stock shall be conclusively deemed to be the “current market price” per share of the Common Stock multiplied by 1,000 (as such amount may be appropriately adjusted to reflect any stock split, reverse stock split, stock dividend, or any similar transaction with respect to Common Stock occurring after the date of this Agreement. If neither the Common Stock nor the Series A Preferred Stock is publicly held or so listed or traded, “current market price” per share of Series A Preferred Stock shall mean the fair value per share as determined in good faith by the Board of Directors, 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. For all purposes of this Agreement, the “current market price” of a Unit of Series A Preferred Stock shall be equal to the “current market price” of one share of Series A Preferred Stock divided by 1,000.

(e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least one percent 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 ten-thousandth of a Common Share or Common Equity Interest or other share or one-millionth of a share of Series A Preferred Stock, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction that mandates such adjustment or (ii) the Expiration Date.

(f) If, as a result of an adjustment made pursuant to Sections 11(a)(ii) or 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Series A Preferred Stock, thereafter the number of such other shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Series A Preferred Stock contained in Sections 11(a), (b), (c), (d), (e), (g), (h), (i), (j), (k), (1), and (m), and the provisions of Sections 7, 9, 10, 13, and 14 hereof with respect to the Series A Preferred Stock 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 Units of Series A Preferred Stock (or other securities or amount of cash or combination thereof) that may be acquired 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 Units of Series A Preferred Stock (calculated to the nearest one ten-thousandth of a Unit) obtained by (i) multiplying (x) the number of Units of Series A Preferred Stock covered by a Right immediately prior to this adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in lieu of any adjustment in the number of Units of Series A Preferred Stock that may be acquired upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of Units of Series A Preferred Stock 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 of a Right) 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, and notify the Rights Agent in writing, 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 Rights Certificates have been issued, shall be at least ten days later than the date of such public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such

adjustment. Rights Certificates to be so distributed shall be issued, executed, and countersigned in the manner provided for herein (and 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 Rights 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 Units of Series A Preferred Stock issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price per Unit and the number of Units of Series A Preferred Stock that was expressed in the initial Rights Certificates issued hereunder.

(k) Before taking any action that would cause an adjustment reducing the Purchase Price below the then par value of the number of Units of Series A Preferred Stock 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 such fully paid and non-assessable number of Units of Series A Preferred Stock 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 (and shall notify the Rights Agent in writing of any such election) until the occurrence of such event the issuance to the holder of any Right exercised after such record date of that number of Units of Series A Preferred Stock and shares of other capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of Units of Series A Preferred Stock and shares of 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 (fractional or otherwise) or securities upon the occurrence of the event requiring such adjustment.

(m) Anything in this Section 11 to the contrary notwithstanding, prior to the Distribution Date, 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 shall determine that any (i) consolidation or subdivision of the Series A Preferred Stock, (ii) issuance wholly for cash of any shares of Series A Preferred Stock at less than the current market price, (iii) issuance wholly for cash of shares of Series A Preferred Stock or securities that by their terms are convertible into or exchangeable for shares of Series A Preferred Stock, (iv) stock dividends, or (v) issuance of rights, options, or warrants referred to in this Section 11, hereafter made by the Company to holders of its Series A Preferred Stock, shall not be taxable to such holders or shall reduce the taxes payable by such holders.

(n) The Company shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a direct or indirect, wholly-owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a direct or indirect, wholly-owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole)

to any other Person or Persons (other than the Company and/or any of its direct or indirect, wholly-owned Subsidiaries in one or more transactions, each of which complies with Section 11(o) hereof), if (x) at the time of or immediately after such consolidation, merger, or sale there are any rights, warrants, or other instruments or securities outstanding or agreements in effect that would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights or (y) prior to, simultaneously with, or immediately after such consolidation, merger, or sale, the Person that constitutes, or would constitute, the “Principal Party” for purposes of Section 13(a) hereof shall have distributed or otherwise transferred to its shareholders or other persons holding an equity interest in such Person Rights previously owned by such Person or any of its Affiliates and Associates; provided, however, that this Section 11(n) shall not affect the ability of any Subsidiary of the Company to consolidate with, merge with or into, or sell or transfer assets or earning power to, any other Subsidiary of the Company.

(o) After the Distribution Date and so long as any Rights shall then be outstanding (other than Rights that have become null and void pursuant to Section 7(e) hereof), the Company shall not, except as permitted by Sections 23, 24, and 27 hereof, take (or permit any Subsidiary of the Company to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

(p) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time after the Effective Date and prior to the Distribution Date (i) declare a dividend on the outstanding Common Shares payable in Common Shares, (ii) subdivide any outstanding Common Shares, (iii) combine any of the outstanding Common Shares into a smaller number of shares, or (iv) issue any shares of its capital stock in a reclassification of the Common Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), the number of Rights associated with each Common Share then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be proportionately adjusted so that the number of Rights thereafter associated with each Common Share following any such event shall equal the result obtained by multiplying the number of Rights associated with each Common Share immediately prior to such event by a fraction the numerator of which shall be the total number of Common Shares outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of Common Shares outstanding immediately following the occurrence of such event. The adjustments provided for in this Section 11(p) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination, or reclassification is effected. If an event occurs that would require an adjustment under Section 11(a)(ii) and this Section 11(p), the adjustments provided for in this Section 11(p) shall be in addition and prior to any adjustment required pursuant to Section 11(a)(ii).

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

to the Distribution Date, to each holder of a certificate representing Common Shares) in accordance with Section 26 hereof. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment or statement therein contained and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of, any adjustment or any such event unless and until it shall have received such a certificate.

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

(a) At any time after a Person has become an Acquiring Person, in the event that, directly or indirectly, either (x) the Company shall consolidate with, or merge with and into, any other Person (other than a direct or indirect, wholly-owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), and the Company shall not be the continuing or surviving entity of such consolidation or merger, (y) any Person (other than a direct or indirect, wholly-owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof) shall consolidate with, or merge with or into, the Company, and the Company shall be the continuing or surviving entity of such consolidation or merger and, in connection with such consolidation or merger, all or part of the outstanding Common Shares shall be converted into or exchanged for stock or other securities of any other Person (or the Company) or cash or any other property or (z) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer) to any Person or Persons (other than the Company or any of its direct or indirect, wholly-owned Subsidiaries in one or more transactions, each of which complies with Section 11(o) hereof), 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) (any such event described in (x), (y), or (z) being herein referred to as a “Section 13 Event”); then, and in each such case, proper provision shall be made so that:

(i) each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive, upon the exercise thereof at the then current Purchase Price multiplied by the number of Units of Series A Preferred Stock for which a Right is then exercisable, in accordance with the terms of this Agreement and in lieu of Units of Series A Preferred Stock, such number of validly authorized and issued, fully paid, and non-assessable shares of Common Equity Interest of the Principal Party (which shares shall not be subject to any liens, encumbrances, rights of first refusal, transfer restrictions, or other adverse claims) as shall be equal to the result obtained by (1) multiplying such then current Purchase Price by the number of Units of Series A Preferred Stock for which such Right is exercisable immediately prior to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section 13 Event, multiplying the number of such Units of Series A Preferred Stock for which a Right would be exercisable hereunder but for the occurrence of such Section 11(a)(ii) Event by the Purchase Price that would be in effect hereunder but for such first occurrence) and (2) dividing that product (which, following the first occurrence of a Section 13 Event, shall be the “Purchase Price” for all purposes of this Agreement) by 50% of the then current market price (determined pursuant to Section 11(d) hereof) per share of the Common Equity Interest of such Principal Party on the date of consummation of such Section 13 Event;

(ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement;

(iii) the term “Company” shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence of a Section 13 Event;

(iv) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of shares of its Common Equity Interest) 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 possible, to its shares of Common Equity Interest thereafter deliverable upon the exercise of the Rights; and

(v) the provisions of Section 11(a)(ii) hereof shall be of no further effect following the first occurrence of any Section 13 Event, and the Rights that have not theretofore been exercised shall thereafter become exercisable in the manner described in this Section 13.

(b) “Principal Party” shall mean:

(i) in the case of any transaction described in clause (x) or (y) of the first sentence of Section 13(a), (A) the Person (including the Company as successor thereto or as the surviving entity) that is the issuer of any securities or other equity interests into which shares of Common Stock are converted in such merger or consolidation, or, if there is more than one such issuer, the issuer of Common Equity Interest that has the highest aggregate current market price (determined pursuant to Section 11(d) hereof) and (B) if no securities or other equity interests are so issued, the Person (including the Company as successor thereto or as the surviving entity) that is the other constituent party to such merger or consolidation, or, if there is more than one such Person, the Person that is a constituent party to such merger or consolidation, the Common Equity Interest of which has the highest aggregate current market price (determined pursuant to Section 11(d) hereof); and

(ii) in the case of any transaction described in clause (z) of the first sentence of Section 13(a), the Person that is the party receiving the largest portion of the assets or earning power transferred pursuant to such transaction or transactions, or, if each Person that is a party to such transaction or transactions receives the same portion of the assets or earning power transferred pursuant to such transaction or transactions or if the Person receiving the largest portion of the assets or earning power cannot be determined, whichever Person that has received assets or earning power pursuant to such transaction or transactions, the Common Equity Interest of which has the highest aggregate current market price (determined pursuant to Section 11(d) hereof);

provided, however, that in any such case, (1) if the Common Equity Interest of such Person is not at such time and has not been continuously over the preceding twelve-month period registered

under Section 12 of the Exchange Act (“Registered Common Equity Interest”), and such Person is a direct or indirect Subsidiary of another Person that has Registered Common Equity Interest outstanding, “Principal Party” shall refer to such other Person; (2) if the Common Equity Interest of such Person is not Registered Common Equity Interest, and such Person is a direct or indirect Subsidiary of another Person (other than an individual), but is not a direct or indirect Subsidiary of another Person that has Registered Common Equity Interest outstanding, “Principal Party” shall refer to the ultimate parent entity of such first-mentioned Person; (3) if the Common Equity Interest of such Person is not Registered Common Equity Interest, and such Person is directly or indirectly controlled by more than one Person, and one or more of such other Persons has Registered Common Equity Interest outstanding, “Principal Party” shall refer to whichever of such other Persons is the issuer of the Registered Common Equity Interest having the highest aggregate current market price (determined pursuant to Section 11(d) hereof); and (4) if the Common Equity Interest of such Person is not Registered Common Equity Interest, and such Person is directly or indirectly controlled by more than one Person (one or more of which is a Person other than an individual), and none of such other Persons has Registered Common Equity Interest outstanding, “Principal Party” shall refer to whichever ultimate parent entity is the corporation having the greatest stockholders’ equity or, if no such ultimate parent entity is a corporation, shall refer to whichever ultimate parent entity is the entity having the greatest net assets.

(c) The Company shall not consummate any Section 13 Event unless the Principal Party shall have a sufficient number of authorized shares of its Common Equity Interest that have not been issued (or reserved for issuance) or that are held in its treasury to permit the exercise in full of the Rights in accordance with this Section 13, and unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in paragraphs (a) and (b) of this Section 13 and further providing that the Principal Party shall use its best efforts to:

(i) (A) prepare and file on an appropriate form, as soon as practicable following the execution of such agreement, a registration statement under the Securities Act with respect to the shares of Common Equity Interest that may be acquired upon exercise of the Rights, (B) cause such registration statement to remain effective (and to include a prospectus at all times complying with the requirements of the Securities Act) until the Expiration Date, and (C) take such action as may be required to ensure that any acquisition of such shares of Common Equity Interest upon the exercise of the Rights complies with any applicable state security or “Blue Sky” laws as soon as practicable following the execution of such agreement;

(ii) as soon as practicable after the execution of such agreement, deliver to holders of the Rights historical financial statements for the Principal Party and each of its Affiliates that comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act; and

(iii) obtain any and all regulatory approvals as may be required with respect to the shares of Common Equity Interest securities that may be acquired upon exercise of the Rights.

(d) In case the Principal Party that is to be a party to a transaction referred to in this Section 13 has at the time of such transaction, or immediately following such transaction will have, a provision in any of its authorized securities or in its certificate of incorporation or by-laws or other instrument governing its affairs, or any other agreements or arrangements, which provision would have the effect of (i) causing such Principal Party to issue, in connection with, or as a consequence of, the consummation of a transaction referred to in this Section 13, shares of Common Equity Interest of such Principal Party at less than the then current market price per share (determined pursuant to Section 11(d) hereof) or securities exercisable for, or convertible into, Common Equity Interest of such Principal Party at less than such then current market price (other than to holders of Rights pursuant to this Section 13); (ii) providing for any special payment, tax, or similar provisions in connection with the issuance of the Common Equity Interest of such Principal Party pursuant to the provisions of Section 13; or (iii) otherwise eliminating or substantially diminishing the benefits intended to be afforded by the Rights in connection with, or as a consequence of, the consummation of a transaction referred to in this Section 13; then, in such event, the Company shall not consummate any such transaction unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing that the provision in question of such Principal Party shall have been cancelled, waived, or amended, or that the authorized securities shall be redeemed, so that the applicable provision will have no effect in connection with, or as a consequence of, the consummation of the proposed transaction.

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

Section 14. Fractional Rights; Fractional Shares; Waiver. (a) The Company shall not be required to issue fractions of Rights or to distribute Rights Certificates that evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the Persons to which such fractional Rights would otherwise be issuable, an amount in cash equal to such fraction of the market value of a whole Right. For purposes of this Section 14(a), the market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date that such fractional Rights would have been otherwise issuable. The closing price of the Rights for any day shall be, if the Rights are listed or admitted to trading on a national securities exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors. 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 shall be used and such determination shall be described in a statement filed with the Rights Agent and delivered to the holders of the Rights, which shall be conclusive for all purposes.

(b) The Company shall not be required to issue fractions of shares of Series A Preferred Stock (other than fractions that are integral multiples of one one-thousandth of a share of Series A Preferred Stock) upon exercise of the Rights or to distribute certificates that evidence such fractional shares of Series A Preferred Stock (other than fractions that are integral multiples of one one-thousandth of a share of Series A Preferred Stock). Subject to Section 7(c)(1) hereof, fractions of shares of Series A Preferred Stock in integral multiples of one one-thousandth of a share of Series A Preferred Stock may, at the election of the Company, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Company and a Depositary Agent selected by it; provided, however, 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 shares of Series A Preferred Stock represented by such depositary receipts. In lieu of such fractional shares of Series A Preferred Stock that are not integral multiples of one one-thousandth of a share, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the then current market price of a share of Series A Preferred Stock on the day of exercise, determined in accordance with Section 11(d) hereof.

(c) The holder of a Right, by the acceptance of the Right, expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 14.

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

Section 16. Agreement of Rights 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 Common Shares;

(b) after the Distribution Date, the Rights Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for

such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates duly executed;

(c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Distribution Date, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights Certificates or the associated Common Share certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to the last sentence of Section 7(e) hereof, shall be affected by any notice to the contrary; and

(d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or any other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree, judgment, 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; provided, however, the Company must use its best efforts to have any such order, decree, judgment, or ruling lifted or otherwise overturned as promptly as practicable.

Section 17. Rights Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the number of shares of Series A Preferred Stock 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 Rights Certificate be construed to confer upon the holder of any Rights 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, except as provided in Section 25 hereof, to receive notice of meetings or other actions affecting shareholders, or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof.

Section 18. Concerning the Rights Agent. (a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses, including reasonable fees and disbursements of counsel and other reasonable disbursements, incurred in the preparation, delivery, amendment, administration, or execution of this Agreement and the acceptance, administration, 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, damage, judgment, fine, penalty, claim, demand, settlement, cost, or expense (including, without limitation, the reasonable fees and disbursements of counsel), incurred without negligence, bad faith, or willful misconduct on the part of the Rights Agent, for any action taken, suffered, or omitted by the Rights Agent in connection with the acceptance, administration, exercise, and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability hereunder.

(b) The Rights Agent shall be authorized and protected and shall incur no liability for, or in respect of any action taken, suffered, or omitted by it in connection with, its acceptance and administration of this Agreement and the exercise and performance of its duties hereunder, in reliance upon any Rights Certificate or certificate for shares of Series A Preferred Stock or for other capital stock or 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 have been signed, executed and, where necessary, verified or acknowledged by the proper Person or Persons.

(c) The provisions of this Section 18 and Section 20 below shall survive the termination of this Agreement, the exercise or expiration of the Rights, and the resignation, replacement, or removal of the Rights Agent.

Section 19. Merger or Consolidation or Change of Name of Rights Agent. (a) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the corporate trust or shareholder services businesses 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 document or any further act on the part of any of the parties hereto; provided, however, that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, any successor Rights Agent may countersign such Rights 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 Rights Certificates shall have the full force provided in the Rights 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 Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

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

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company or an employee of the Rights Agent), and the advice or opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to, and the Rights

Agent shall incur no liability for or in respect of, any action taken, suffered, or omitted by the Rights Agent in good faith and in accordance with such advice or 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 an Acquiring Person and the determination of “current market price”) be proved or established by the Company prior to the Rights Agent taking, suffering, or omitting to take any action hereunder, such fact or matter (unless other evidence in respect thereof be specified herein) may be deemed to be conclusively proved and established by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the President, the Vice-Chairman of the Board, the Treasurer, any Assistant Treasurer, the Secretary, or any Assistant Secretary of the Company and delivered to the Rights Agent, and such certificate shall be full and complete authorization and protection to the Rights Agent, and the Rights Agent shall incur no liability, for or in respect of any action taken, suffered, or omitted in good faith by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent shall be liable hereunder to the Company or any other Person only for its own negligence, bad faith, or willful misconduct. Anything herein to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential, or incidental loss or damage of any kind whatsoever (including but not limited to lost profits).

(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 Rights Certificates or be required to verify the same (except as to its countersignature on such Rights Certificates), 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 have any responsibility for the validity of this Agreement or the execution and delivery hereof (except the due execution and delivery hereof by the Rights Agent) or for the validity or execution of any Rights Certificate (except its countersignature thereon); nor shall it be responsible for any breach by the Company of any covenant or failure by the Company to satisfy conditions contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including Rights becoming void pursuant to Section 7(e) hereof) or any adjustment in the terms of the Rights required under the provisions of Sections 11, 13, 23, or 24 hereof or for the manner, method, or amount of any such change or 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 Rights Certificates after receipt by the Rights Agent of the certificate describing any such adjustment contemplated by Section 12); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Series A Preferred Stock or any other securities to be issued pursuant to this Agreement or any Rights Certificate or as to whether any shares of Series A Preferred Stock or any other securities will, when so issued, be validly authorized and issued, fully paid and non-assessable.

(f) The Company shall perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all such further acts, instruments, and

assurances as may reasonably be required by the Rights Agent for the performance by the Rights Agent of its duties under this Agreement.

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

(h) The Rights Agent and any shareholder, affiliate, 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 become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though the Rights Agent were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent or any such stockholder, affiliate, director, officer, or employee from acting in any other capacity for the Company or for any other Person.

(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 (through its directors, officers, and employees) 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 or any other Person resulting from any such act, default, neglect, or misconduct, absent gross negligence, bad faith, or willful misconduct of the Rights Agent 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 hereunder if the Rights Agent shall have 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 Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase, as the case may be, has not been completed, has not been signed, or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company. If such certificate has been completed and signed and shows a negative response to clauses 1 and 2 of such certificate, unless previously instructed otherwise in writing by the Company (which instructions may impose on the Rights Agent additional ministerial responsibilities, but no discretionary responsibilities), the Rights Agent may assume without further inquiry that the Rights Certificate is not owned by a person described in Section 4(b) or Section 7(e) hereof and shall not be charged with any knowledge to the contrary.

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 thirty days’ prior notice in writing mailed to the Company, and to each transfer agent of the Series A Preferred Stock and the Common Shares, by registered or certified mail, in which case the Company shall give or cause to be given written notice to the registered holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon thirty days’ prior notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Series A Preferred Stock and the Common Shares, by registered or certified mail, and to the registered holders of the Rights Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of thirty 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 Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then any registered holder of any Rights 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 Person organized and doing business under the laws of the United States or any state of the United States, in good standing, shall be authorized under such laws to exercise corporate trust, stock transfer, or shareholder services powers, shall be subject to supervision or examination by federal or state authorities, and shall have at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000 or (b) an Affiliate of a Person described in clause (a) of this sentence. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Series A Preferred Stock and the Common Shares, and mail a notice thereof in writing to the registered holders of the Rights Certificates by first-class mail. 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.

Section 22. Issuance of New Rights Certificates. Notwithstanding any of the provisions of this Agreement or the Rights Certificates to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by a majority of the Board of Directors to reflect any adjustment or change made in accordance with the provisions of this Agreement in the Purchase Price or the number or kind or class of shares or other securities or property that may be acquired under the Rights Certificates. In addition, in connection with the issuance or sale of Common Shares following the Distribution Date and prior to the Expiration Date, the Company (a) shall, with respect to Common Shares so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company, and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights Certificate shall be issued

if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the person to whom such Rights Certificate would be issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

Section 23. Redemption and Termination. (a) The Board of Directors may, within its sole discretion, at any time prior to the earlier of (i) such time as any Person becomes an Acquiring Person and (ii) the Final Expiration Date, redeem all, but not less than all, of the then outstanding Rights at a redemption price of $0.0001 per Right, rounded up to the nearest whole cent, appropriately adjusted to reflect any stock split, reverse stock split, stock dividend, or similar transaction occurring after the date hereof (such redemption price, as adjusted, being hereinafter referred to as the “Redemption Price”). The redemption of the Rights by the Board of Directors pursuant to this paragraph (a) 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. The Company may, at its option, pay the Redemption Price in cash, Common Shares (based on the current market price (determined pursuant to Section 11(d) hereof) of the Common Stock at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors.

(b) If the Company receives a Qualified Offer and the Board of Directors of the Company has not redeemed the outstanding Rights or exempted such offer from the terms of this Agreement or called a special meeting of stockholders for the purpose of voting on whether or not to exempt such Qualified Offer from the terms of this Agreement, in each case by the end of the 90 days following the commencement of such Qualified Offer, and if the Company receives, not earlier than 90 days nor later than 120 days following the commencement of such Qualified Offer, a written notice complying with the terms of this Section 23(b) (the “Special Meeting Notice”), properly executed by the holders of record (or their duly authorized proxy) of ten percent (10%) or more of the shares of Common Stock then outstanding (excluding shares of Common Stock beneficially owned by the Person making the Qualified Offer and such Person’s Affiliates and Associates), directing the Board of Directors of the Company to submit to a vote of stockholders at a special meeting of the stockholders of the Company (a “Special Meeting”) a resolution authorizing the redemption of all, but not less than all, of the then outstanding Rights at the Redemption Price (the “Redemption Resolution”), then the Board of Directors of the Company shall take such actions as are necessary or desirable to cause the Redemption Resolution to be submitted to a vote of stockholders within ninety days following receipt by the Company of the Special Meeting Notice (the “Special Meeting Period”), by including a proposal relating to adoption of the Redemption Resolution in the proxy materials of the Company for the Special Meeting; provided, however, that if the Company, at any time during the Special Meeting Period and prior to a vote on the Redemption Resolution, enters into a Definitive Acquisition Agreement, the Special Meeting Period may be extended (and any Special Meeting called in connection therewith may be cancelled) if the Redemption Resolution will be separately submitted to a vote at the same meeting as the Definitive Acquisition Agreement. For purposes of a Special Meeting Notice, the record date for determining eligible holders of record of the Common Stock shall be the ninetieth day following the commencement of a Qualified Offer. Any Special Meeting Notice must be delivered to the Secretary of the Company at the principal executive offices of the Company and must set forth, as to the stockholders of record executing

such Special Meeting Notice, (i) the name and address of such stockholders, as they appear on the Company’s books and records, (ii) the number of shares of Common Stock that are owned of record by each of such stockholders and (iii) in the case of Common Stock that is owned beneficially by another Person, an executed certification by the holder of record that such holder has executed such Special Meeting Notice only after obtaining instructions to do so from such beneficial owner. Subject to the requirements of applicable law, the Board of Directors of the Company may take a position in favor of or opposed to the adoption of the Redemption Resolution, or no position with respect to the Redemption Resolution, as it determines to be appropriate in the exercise of its fiduciary duties. In the event that (A) no Person has become an Acquiring Person prior to the effective date of redemption referred to below in this sentence, (B) the Qualified Offer continues to be a Qualified Offer prior to the last day of the Special Meeting Period (the “Outside Meeting Date”) and (C) either (1) the Special Meeting is not held on or prior to the ninetieth day following receipt of the Special Meeting Notice or (2) at the Special Meeting at which a quorum is present, the holders of a majority of the shares of Common Stock outstanding as of the record date for the Special Meeting selected by the Board of Directors of the Company (excluding shares of Common Stock beneficially owned by the Person making the Qualified Offer and such Person’s Affiliates and Associates), shall vote in favor of the Redemption Resolution, then all of the Rights shall be deemed redeemed at the Redemption Price by such failure to hold the Special Meeting or as a result of the adoption of the Redemption Resolution by the stockholders of the Company (or the Board of Directors of the Company shall take such other action as may be necessary to prevent the existence of the Rights from interfering with the consummation of the Qualified Offer), such redemption to be effective, as the case may be, (x) as of the close of business on the Outside Meeting Date if a Special Meeting is not held on or prior to such date or (y) if a Special Meeting is held on or prior to the Outside Meeting Date, as of the date on which the results of the vote adopting the Redemption Resolution at the Special Meeting are certified as official by the appointed inspectors of election for the Special Meeting.

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

Section 24. Exchange. (a) The Board of Directors 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 null and void pursuant to the provisions of Section 7(e) hereof) for Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend, or similar transaction occurring after the date hereof (such exchange ratio being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Acquiring Person, together with all Affiliates and Associates of such Acquiring Person, becomes the Beneficial Owner of shares of Voting Stock representing 50% or more of the total Voting Power of the aggregate of all shares of Voting Stock then outstanding.

(b) Immediately upon the action of the Board of Directors 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 shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give (i) written notice to the Rights Agent of any such exchange and (ii) 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 that 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 shares of Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights that will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights that have become void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights.

(c) In the event that there are not sufficient shares of Common Stock issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 24, the Company shall take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exchange of the Rights. In the event the Company, after good faith effort, is unable to take all such action as may be necessary to authorize such additional shares of Common Stock, the Company shall substitute Units of Series A Preferred Stock (or Equivalent Preferred Stock) for Common Stock exchangeable for Rights, at the initial rate of one Unit of Series A Preferred Stock (or Equivalent Preferred Stock) for each share of Common Stock, as appropriately adjusted to reflect stock splits, stock dividends, and other similar transactions after the date hereof.

Section 25. Notice of Certain Events. (a) In case the Company shall propose, at any time after the Distribution Date, (i) to pay any dividend payable in stock of any class or series to the holders of Series A Preferred Stock or to make any other distribution to the holders of Series A Preferred Stock (other than a regular quarterly cash dividend out of earnings or retained earnings of the Company); (ii) to offer to the holders of Series A Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Series A Preferred Stock or shares of stock of any class or any other securities, rights or options; (iii) to effect any

reclassification of Series A Preferred Stock (other than a reclassification involving only the subdivision of outstanding shares of Series A Preferred Stock); (iv) to effect any consolidation or merger into or with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), 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 more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof); or (v) to effect the liquidation, dissolution or winding up of the Company; then, in each such case, the Company shall give to each registered holder of a Rights Certificate, to the extent feasible, and to the Rights Agent in accordance with Section 26 hereof, a written notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the shares of Series A Preferred Stock 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 (10) days prior to the record date for determining holders of the shares of Series A Preferred Stock for purposes of such action, and in the case of any such other action, at least ten (10) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the shares of Series A Preferred Stock whichever shall be the earlier; provided, however, that no such action shall be taken pursuant to this Section 25(a) that will or would conflict with any provision of the Certificate of Incorporation; provided further, that no such notice shall be required pursuant to this Section 25, if any Subsidiary of the Company effects a consolidation or merger with or into, or effects a sale or other transfer of assets or earnings power to, any other Subsidiary of the Company.

(b) In case any of the events set forth in Section 11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall, as soon as practicable thereafter, give to each holder of a Rights Certificate, to the extent feasible, and to the Rights Agent in accordance with Section 26 hereof, a written notice of the occurrence of such event, which notice shall describe such event and the consequences of the event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all references in the preceding Section 25(a) to Series A Preferred Stock shall be deemed to refer, if appropriate, to any other securities that may be acquired upon exercise of a Right.

(c) In case any Section 13 Event shall occur, then the Company shall, as soon as practicable thereafter, give to each registered holder of a Rights Certificate, to the extent feasible, and to the Rights Agent in accordance with Section 26 hereof, a written 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 13(a) hereof.

Section 26. Notices. All notices and other communications provided for hereunder shall, unless otherwise stated herein, be in writing (including by facsimile, telegram or cable) and mailed or sent or delivered, if to the Company, at its address at:

Section 27. Supplements and Amendments. Subject to the penultimate sentence of this Section 27, the Company, by action of the Board of Directors, may from time to time supplement or amend this Agreement without the approval of any holders of Rights in order to cure any ambiguity, to correct or supplement any provision contained herein that may be defective or inconsistent with any other provisions herein, to shorten or lengthen any time period hereunder, or to make any other provisions with respect to the Rights that the Company may deem necessary or desirable, any such supplement or amendment to be evidenced by a writing signed by the Company and the Rights Agent; provided, however, that from and after such time as any Person becomes an Acquiring Person, this Agreement shall not be amended in any manner that would adversely affect the interests of the holders of Rights (other than Rights that have become null and void pursuant to Section 7(e) hereof). Without limiting the foregoing, the Company, by action of the Board of Directors, may at any time prior to such time as any Person becomes an Acquiring Person amend this Agreement (A) to make the provisions of this Agreement inapplicable to a particular transaction by which a Person would otherwise become an Acquiring Person or to otherwise alter the terms and conditions of this Agreement as they may apply with respect to any such transaction; and (B) to lower the thresholds set forth in Sections 1(a) and 3(a) to not less than the greater of (i) the sum of 0.001% and the largest percentage of Voting Power represented by the then outstanding shares of Voting Stock then known by the Company to be Beneficially Owned by any Person (other than a Grandfathered Stockholder, the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any trustee or fiduciary holding shares of Voting Stock for, or pursuant to the terms of, any such plan, acting in such capacity), and (ii) 10%. Upon delivery of a certificate from an appropriate officer of the Company that states that the proposed supplement or amendment is in compliance with the terms of this Section 27, the Rights Agent shall execute such supplement or amendment; provided, however, that no supplement or amendment may be made to Sections 18, 19, 20, or 21 hereof without the consent of the Rights Agent. Prior to the Distribution Date, the interests of the holders of Rights shall be deemed coincident with the interests of the holders of Common Shares.

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

Section 29. Determinations and Actions by the Board of Directors. For all purposes of this Agreement, any calculation of the number of shares of any class or series of Voting Stock outstanding at any particular time, including for purposes of determining the particular percentage of outstanding shares of Voting Stock of which any Person is the Beneficial Owner (or the particular percentage of total Voting Power of such outstanding shares of Voting Stock represented by shares of Voting Stock of which any Person is the Beneficial Owner), shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the Exchange Act Regulations as in effect on the date hereof. Except as otherwise specifically provided herein, the Board of Directors shall have the exclusive power and authority to administer this Agreement and to exercise all rights and powers specifically granted to the Board of Directors or to the Company hereunder, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power (i) to interpret the provisions of this Agreement, and (ii) to make all determinations deemed necessary or advisable for the administration of this Agreement. All such actions, calculations, interpretations and determinations (including, for purposes of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Board of Directors shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties, and (y) not subject the Board of Directors or any member thereof to any liability to the holders of the Rights.

Section 30. Benefits of this Agreement. Nothing in this Agreement shall be construed to give to any Person other than the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of Common Shares) any legal or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of Common Shares).

Section 31. Severability. If any term, provision, covenant, or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

Section 32. Governing Law. This Agreement, each Right, and each Rights Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts to be made and performed entirely within such State.

Section 33. Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same instrument.

Section 34. Descriptive Headings. The headings contained in this Agreement are for descriptive purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

SUMMARY OF RIGHTS TO PURCHASE
SERIES A PREFERRED STOCK

On June 2, 2008, the Board of Directors (the “Board of Directors”) of MarketAxess Holdings Inc. (the “Company”) implemented a stockholders rights agreement and declared a distribution of one right (a “Right”) for each outstanding share of common stock, par value $0.003 per share (the “Common Stock”), and nonvoting common stock, par value $0.003 per share, of the Company (the “Nonvoting Common Stock” and, together with the Common Stock, the “Common Shares”) to stockholders of record at the close of business on June 20, 2008 (the “Record Date”) and for each Common Share issued (including Common Shares issued from the Company’s treasury) by the Company thereafter and prior to the Distribution Date (as defined below). Each Right entitles the registered holder, subject to the terms of the Stockholders Rights Agreement (as defined below), to purchase from the Company one one-thousandth of a share (a “Unit”) of Series A Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”), at a price of $40.00 per Unit, subject to adjustment (the “Purchase Price”).

The description and terms of the Rights are set forth in a Stockholders Rights Agreement, dated as of June 2, 2008 (the “Stockholders Rights Agreement”), by and between the Company and American Stock Transfer & Trust Company, LLC (the “Rights Agent”). Copies of the Stockholders Rights Agreement and the Certificate of Designation for the Series A Preferred Stock have been filed with the Securities and Exchange Commission as exhibits to a Registration Statement on Form 8-A dated June 2, 2008 (the “Form 8-A”). Copies of the Stockholders Rights Agreement and the Certificate of Designation are available free of charge from the Company. This summary description of the Rights and Series A Preferred Stock does not purport to be complete and is qualified in its entirety by reference to all the provisions of the Stockholders Rights Agreement and the Certificate of Designation, including the definitions therein of certain terms, which Stockholders Rights Agreement and Certificate of Designation are incorporated herein by reference. Capitalized terms herein and defined in the Stockholders Rights Agreement and not otherwise defined herein shall have the meaning set forth in the Stockholders Rights Agreement.

The Stockholders Rights Agreement

Initially, the Rights will attach to all certificates representing Common Shares then outstanding, and no separate Rights Certificates will be distributed. The Rights will separate from the Common Shares and the “Distribution Date” will occur upon the earlier of (i) ten business days following a public announcement that a person or group of affiliated or associated persons has become an “Acquiring Person” or (ii) ten business days (or such later date as may be determined by the Board of Directors prior to such time as any person becomes an Acquiring Person) following the commencement of a tender or exchange offer that would result in a person or group of affiliated and associated persons beneficially owning an aggregate of 20% or more of the total voting power represented by all the then

outstanding shares of Common Stock and other voting securities of the Company (the “Voting Securities”) if, upon consummation thereof, such person would be the beneficial owner of Voting Securities representing 20% or more of the total Voting Securities then outstanding. Until the Distribution Date, (i) the Rights will be evidenced by certificates for Common Shares and will be transferred with and only with such share certificates, (ii) new certificates for Common Shares issued after the Record Date (including Common Shares distributed from the Company’s treasury) will contain a notation incorporating the Stockholders Rights Agreement by reference and (iii) the surrender for transfer of any certificates representing outstanding Common Shares will also constitute the transfer of the Rights associated with the Common Shares represented by such certificates.

An “Acquiring Person” is a person or group of affiliated or associated persons that has acquired, obtained the right to acquire, or otherwise obtained beneficial ownership of an aggregate of 20% or more of the total voting power represented by all the then outstanding shares of Voting Securities. The following, however, are not considered Acquiring Persons: (1) the Company, its subsidiaries, any employee benefit plan of the Company or any of its subsidiaries, or any entity holding shares of Voting Securities pursuant to the terms of any such plan; (2) any person or group that becomes the Beneficial Owner of 20% or more of the total voting power represented by all the then outstanding Voting Securities solely as a result of the acquisition of Voting Securities by the Company, unless such person or group thereafter acquires beneficial ownership of additional Voting Securities; (3) subject to certain conditions set forth in the Stockholders Rights Agreement, a person or group that otherwise would have become an Acquiring Person as a result of an inadvertent acquisition of 20% or more of the total voting power represented by all the then outstanding Voting Securities; and (4) subject to certain conditions set forth in the Stockholders Rights Agreement, any person or group that would otherwise be deemed an Acquiring Person upon adoption of the Stockholders Rights Agreement (a “Grandfathered Stockholder”). Except as provided in the Stockholders Rights Agreement, a person or group that is a Grandfathered Stockholder will cease to be a Grandfathered Stockholder and will become an Acquiring Person if after adoption of the Stockholders Rights Agreement such Grandfathered Stockholder acquires beneficial ownership of additional Voting Securities in excess of one percent of the number of shares of Common Stock outstanding as of June 2, 2008.

The Rights are not exercisable until the Distribution Date and will expire at the close of business on the third anniversary of the Stockholders Rights Agreement unless earlier redeemed or exchanged by the Company as described below.

As soon as practicable after the Distribution Date, Rights Certificates will be mailed to holders of record of Common Shares as of the close of business on the Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights.

If a person or group of affiliated or associated persons becomes an Acquiring Person, then each holder of a Right will thereafter have the right to receive, upon exercise, shares of

Common Stock (or, in certain circumstances, Units of Series A Preferred Stock, other securities, cash, property or a combination thereof) having a value equal to two times the exercise price of the Right. The exercise price is the Purchase Price multiplied by the number of Units of Series A Preferred Stock issuable upon exercise of a Right prior to the events described in this paragraph.

Notwithstanding any of the foregoing, following the time any person or group becomes an Acquiring Person, all Rights that are, or under certain circumstances specified in the Stockholders Rights Agreement were, beneficially owned by any Acquiring Person or its Affiliates or Associates will be null and void.

In the event that, at any time after a person or group becomes an “Acquiring Person,” (i) the Company is acquired in a merger or other business combination with another company and the Company is not the surviving corporation, (ii) another company consolidates or merges with the Company and all or part of the shares of Common Stock are converted or exchanged for other securities, cash or property or (iii) 50% or more of the consolidated assets or earning power of the Company and its subsidiaries is sold or transferred to another company, then each holder of a Right (except Rights that previously have been voided as described above) shall thereafter have the right to receive, upon exercise, common stock or other equity interest of the ultimate parent of such other company having a value equal to two times the exercise price of the Right.

The Purchase Price payable, and the number of Units of Series A Preferred Stock (or other securities, as applicable) 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 Series A Preferred Stock, (ii) if holders of the Series A Preferred Stock are granted certain rights or warrants to subscribe for Series A Preferred Stock or convertible securities at less than the current market price of the Series A Preferred Stock or (iii) upon the distribution to the holders of the Series A Preferred Stock of evidences of indebtedness, cash or assets (excluding regular quarterly cash dividends or dividends payable in the Series A Preferred Stock) or of subscription rights or warrants (other than those referred to above).

With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments amount to at least one percent of the Purchase Price. The Company is not required to issue fractional shares of Series A Preferred Stock (other than fractional shares that are integral multiples of one one-thousandth of a share). In lieu thereof, an adjustment in cash may be made based on the market price of the Series A Preferred Stock prior to the date of exercise.

At any time prior to such time as any person or group or affiliated or associated persons becomes an Acquiring Person, the Board of Directors may redeem the Rights in whole, but not in part, at a price of $0.0001 per Right, rounded up to the nearest whole cent (subject to adjustment in certain events) (the “Redemption Price”). Immediately upon the action of the

Board of Directors ordering the redemption of the Rights, the Rights will terminate and the only right of the holders of such Rights will be to receive the Redemption Price for each Right held.

Between 90 and 120 days after the commencement of a Qualified Offer (as such term is defined below), the holders of 10% or more of the Common Stock then outstanding (excluding Common Stock beneficially owned by the Person making the Qualified Offer and such Person’s Affiliates and Associates) may, by notice (a “Special Meeting Notice”), require the Company to call a special meeting of the stockholders to vote on a resolution authorizing the redemption of all, but not less than all, of the then outstanding Rights at the Redemption Price (the “Redemption Resolution”). The Board of Directors must cause the Rights to be redeemed or otherwise prevent the Rights from interfering with the consummation of the Qualified Offer if the special meeting of the stockholders is not held within 90 days of the Special Meeting Notice (which period may be extended to permit the stockholders to vote on a definitive acquisition agreement) or if such meeting is held and the holders of a majority of the outstanding Common Stock (excluding Common Stock beneficially owned by the Person making the Qualified Offer and such Person’s Affiliates and Associates) vote in favor of the Redemption Resolution, in each case as long as at such time no Person has become an Acquiring Person and as long as the Qualified Offer continues to be a Qualified Offer prior to the last day of the period in which the special meeting of the stockholders must be held.

A “Qualified Offer” is an offer determined by a majority of the independent directors of the Company to have each of the following characteristics:

(ii) an offer that has commenced within the meaning of Rule 14d-2(a) under the Exchange Act;

(iii) an offer whose per-share offer price is greater than the highest reported market price for the Common Stock in the immediately preceding twenty-four months, with, in the case of an offer that includes shares of common stock of the offeror, such per-share offer price being determined using the lowest reported market price for common stock of the offeror during the five trading days immediately preceding and immediately following the commencement of such offer within the meaning of Rule 14d-2(a) under the Exchange Act;

(iv) an offer that does not result in a nationally recognized investment banking firm retained by the Board of Directors rendering an opinion to the Board of Directors that the consideration being offered to the stockholders of the Company is either unfair or inadequate;

(v) if the offer includes shares of common stock of the offeror, (A) the offeror must allow the Company’s investment bank, legal counsel and accountants to perform appropriate due diligence on the offeror and (B) such investment bank must not render an opinion to the Board of Directors that the consideration being offered to the stockholders of the Company is either unfair or inadequate and must not later render an opinion to the

Board of Directors that the consideration being offered to the stockholders of the Company has become either unfair or inadequate based on a subsequent disclosure or discovery of a development or developments that have had or are reasonably likely to have a material adverse effect on the value of the common stock of the offeror;

(vi) an offer that is subject to only the minimum tender condition described in Section 1(v)(ix) of the Stockholders Rights Agreement and other customary terms and conditions, which conditions shall not include any financing, funding or similar conditions or any requirements with respect to the offeror or its agents being permitted any due diligence with respect to the books, records, management, accountants or other outside advisors of the Company;

(vii) an offer pursuant to which the Company has received an irrevocable written commitment of the offeror that the offer will remain open for at least 120 Business Days and, if a Special Meeting is duly requested, for at least fifteen Business Days after the date of the Special Meeting or, if no Special Meeting is held within ninety Business Days following receipt of the Special Meeting Notice, for at least fifteen Business Days following such ninety Business Day period;

(viii) an offer pursuant to which the Company has received an irrevocable written commitment of the offeror that, in addition to the minimum time periods specified, the offer, if it would otherwise expire, will be extended for at least twenty Business Days after any increase in the consideration being offered or after any bona fide alternative offer is commenced within the meaning of Rule 14d-2(a) under the Exchange Act; provided, however, that such offer need not remain open beyond (A) the time that any other offer satisfying the criteria for a Qualified Offer is then required to be kept open, (B) the expiration date of any other tender offer for the Common Stock with respect to which the Board of Directors has agreed to redeem the Rights immediately prior to acceptance for payment of the Common Stock thereunder or (C) one Business Day after the stockholder vote with respect to approval of any definitive acquisition agreement has been officially determined and certified by the inspectors of elections;

(xii) an offer (other than an offer consisting solely of cash consideration) pursuant to which the Company has received the written representation and certification of the offeror and, in their individual capacities, the written representations and certifications of the offeror’s Chief Executive Officer and Chief Financial Officer, that (A) all facts about the offeror that would be material to making an investor’s decision to accept the offer have been fully and accurately disclosed as of the date of the commencement of the offer, (B) all such new facts will be fully and accurately disclosed during the entire period which the offer remains open, and (C) all required Exchange Act reports will be filed by the offeror in a timely manner during such period; and

(xiii) if the offer includes non-cash consideration, (A) the non-cash portion of the consideration offered must consist solely of common stock of a Person that is a publicly-owned United States corporation, (B) such common stock must be freely tradable and listed or admitted to trading on either the New York Stock Exchange or NASDAQ, (C) no stockholder approval of the issuer of such common stock is required to issue such common stock, or, if required, such approval has already been obtained, (D) no Person (including such Person’s Affiliates and Associates) beneficially owns more than 15% of the voting stock of the issuer of such common stock at the time of commencement or at any time during the term of the offer, (E) no other class of voting stock of the issuer of such common stock is outstanding and (F) the issuer of such common stock meets the registrant eligibility requirements for use of Form S-3 for registering securities under the Securities Act.

For the purposes of the definition of “Qualified Offer,” “fully financed” shall mean that the offeror has sufficient funds for the offer and related expenses which shall be evidenced by (1) firm, unqualified, written commitments from responsible financial institutions having the necessary financial capacity, accepted by the offeror, to provide funds for such offer subject only to customary terms and conditions, (2) cash or cash equivalents then available to the offeror, set apart and maintained solely for the purpose of funding the offer with an irrevocable written commitment being provided by the offeror to the Board of Directors to maintain such availability until the offer is consummated or withdrawn or (3) a combination of the foregoing; which evidence has been provided to the Company prior to, or upon, commencement of the offer. If an offer becomes a Qualified Offer in accordance with this definition, but subsequently ceases to be a Qualified Offer as a result of the failure at a later date to continue to satisfy any of the requirements of this definition, such offer shall cease to be a Qualified Offer and the applicable provisions of the Stockholders Rights Agreement shall no longer be applicable to such offer, provided that the actual redemption of the Rights shall not have already occurred.

At any time after any person or group of affiliated or associated persons becomes an Acquiring Person and before any such Acquiring Person becomes the beneficial owner of 50%

or more of the total voting power of the aggregate of all shares of Voting Securities then outstanding, the Board of Directors, at its option, may exchange each Right (other than Rights that previously have become void as described above) in whole or in part, at an exchange ratio of one Common Share (or under certain circumstances one Unit of Series A Preferred Stock or equivalent preferred stock) per Right (subject to adjustment in certain events).

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. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Units of Series A Preferred Stock (or other consideration).

Any of the provisions of the Stockholders Rights Agreement may be amended without the approval of the holders of Rights in order to cure any ambiguity, defect, or inconsistency or to make any other changes that the Board of Directors may deem necessary or desirable. After any person or group of affiliated or associated persons becomes an Acquiring Person, the provisions of the Stockholders Rights Agreement may not be amended in any manner that would adversely affect the interests of the holders of Rights (excluding the interests of any Acquiring Person).

Description of Series A Preferred Stock

On June 2, 2008, the Company also filed a Certificate of Designation for the Series A Preferred Stock (the “Series A Certificate of Designation”) with Secretary of State of the State of Delaware. The Series A Certificate of Designation authorizes the Company to issue 110,000 of its 5,000,000 authorized shares of preferred stock as shares of Series A Preferred Stock.

The Units of Series A Preferred Stock that may be acquired upon exercise of the Rights will not be redeemable and will rank junior to any other shares of preferred stock that may be issued by the Company with respect to the payment of dividends and as to distribution of assets in liquidation.

Each share of Series A Preferred Stock will have a minimum preferential quarterly dividend of the greater of $1.00 per share or 1,000 times the aggregate per share amount of any cash dividend declared on the shares of Common Stock since the immediately preceding quarterly dividend, subject to certain adjustments.

In the event of liquidation, the holder of Series A Preferred Stock will be entitled to receive a cash preferred liquidation payment per share equal to the greater of $1.00 (plus accrued and unpaid dividends thereon) or 1,000 times the amount paid in respect of a share of Common Stock, subject to certain adjustments.

Generally, each share of Series A Preferred Stock will vote together with the shares of Common Stock and any other class or series of capital stock entitled to vote on such matter, and will be entitled to 1,000 votes per share, subject to certain adjustments. The holders of the Series A Preferred Stock, voting as a separate class, shall be entitled to elect two directors if dividends on the Series A Preferred Stock are in arrears in an amount equal to six quarterly dividends thereon.

In the event of any merger, consolidation or other transaction in which shares of Common Stock are exchanged, each share of Series A Preferred Stock will be entitled to receive 1,000 times the aggregate per share amount of stock, securities, cash or other property paid in respect of each share of Common Stock, subject to certain adjustments.

The rights of holders of the Series A Preferred Stock to dividend, liquidation and voting rights are protected by customary anti-dilution provisions.

Because of the nature of the Series A Preferred Stock’s dividend, liquidation and voting rights, the economic value of one Unit of Series A Preferred Stock is expected to approximate the economic value of one share of Common Stock.

Amendment of Rights

The terms of the Rights generally may be amended by the Board of Directors without the approval of the holders of the Rights, except that from and after such time as the Rights are distributed, no such amendment may adversely affect the interests of the holders of Rights (excluding any interests of any Acquiring Person).

CERTIFICATE OF DESIGNATION
OF
SERIES A PREFERRED STOCK
OF
MARKETAXESS HOLDINGS INC.

Pursuant to Section 151 of the
General Corporation Law of
the State of Delaware

MarketAxess Holdings Inc., a corporation duly organized and existing under the General Corporation Law of the State of Delaware (the “Corporation”), DOES HEREBY CERTIFY:

That, pursuant to authority conferred by the Corporation’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate”) and by the provisions of Section 151 of the General Corporation Law of the State of Delaware, the board of directors of the Corporation (the “Board of Directors”), at a duly called meeting, at which a quorum was present and acted throughout, adopted the following resolutions, which resolutions remain in full force and effect on the date hereof creating a series of 110,000 shares of Preferred Stock having a par value of $0.001 per share, designated as Series A Preferred Stock:

RESOLVED, that in accordance with the provisions of the Certificate, the Board of Directors does hereby create, authorize and provide for the issuance of a series of Preferred Stock, par value $0.001 per share, of the Corporation, designated as “Series A Preferred Stock,” having the voting rights, powers, preferences and relative, participating, optional and other special rights, preferences, and qualifications, limitations and restrictions thereof that are set forth as follows:

Section 1. Designation and Amount. The shares of such class shall be designated as “Series A Preferred Stock” (the “Series A Preferred Stock”) and the number of shares constituting such class shall be 110,000. Such number of shares may be increased or decreased by resolution of the Board of Directors, provided that no such decrease shall reduce the number of shares of the Series A Preferred Stock to a number less than the number of shares then outstanding, plus the number reserved for issuance upon the exercise of options, rights or warrants, or upon conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Stock.

Section 2. Dividends and Distributions. (A) Subject to the prior and superior rights of the holders of any shares of any other class or series of Preferred Stock of the Corporation ranking prior and superior to the shares of Series A Preferred Stock with respect to

dividends, each holder of a share (a “Share”) of Series A Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for that purpose, (i) quarterly dividends payable in cash on the last day of March, June, September, and December in each year (each such date being a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of such Share of Series A Preferred Stock, 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 thousand (1,000) times an amount equal to (x) the aggregate per share amount of all cash dividends declared on shares of 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 a Share of Series A Preferred Stock, minus (y) the amount in cash actually paid per share of Common Stock pursuant to Section 2(B) below since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of a Share of Series A Preferred Stock, and (ii) subject to the provision for adjustment hereinafter set forth, quarterly distributions (payable in kind) on each Quarterly Dividend Payment Date in an amount per Share equal to one thousand (1,000) times the aggregate per share amount of all 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 shares of 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 a Share of Series A Preferred Stock. In the event that the Corporation shall at any time after June 2, 2008 (the “Rights Declaration Date”) (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine outstanding shares of Common Stock into a smaller number of shares, then in each such case the amount to which the holder of a Share of Series A Preferred Stock was entitled immediately prior to such event pursuant to the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) The Corporation shall declare a dividend or distribution on Shares of Series A Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the shares of Common Stock (other than a dividend or distribution payable in shares of Common Stock); provided, however, that in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Date, a dividend of $1.00 per Share on the Series A Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and shall be cumulative on each outstanding Share of Series A Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issuance of such Share of Series A Preferred Stock, unless the date of issuance of such Share is prior to the record date for the first Quarterly Dividend Payment Date, in which case, dividends on such Share shall begin to accrue from the date of issuance of

such Share, or unless the date of issuance is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of Shares of Series A Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on Shares of Series A Preferred Stock in an amount less than the aggregate amount of all such dividends at the time accrued and payable on such Shares shall be allocated pro rata on a share-by-share basis among all Shares of Series A Preferred Stock at the time outstanding. The Board of Directors may fix a record date for the determination of holders of Shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof.

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

(A) Subject to the provision for adjustment hereinafter set forth, each Share of Series A Preferred Stock shall entitle the holder thereof to one thousand (1,000) votes on all matters submitted to a vote of the holders of Common Stock of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine the outstanding shares of Common Stock into a small number of shares, then in each such case the number of votes per Share to which holders of Shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein or in any other Certificate of Designation creating a series of preferred stock, or any similar stock, or by law, the holders of Shares of Series A Preferred Stock, the holders of shares of Common Stock, and the holders of any other class or series of capital stock of the Corporation entitled to vote generally, together with the Common Stock, shall vote together as one class on all matters submitted to a vote of the holders of such stock.

(C) (i) If at any time dividends on any Shares of Series A Preferred Stock shall be in arrears in an amount equal to six quarterly dividends thereon, then during the period (a “default period”) from the occurrence of such event until such time as all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all Shares of Series A Preferred Stock then outstanding shall have been declared and paid or set apart for payment, the holders of the outstanding Shares of Series A Preferred Stock, together with the holders of outstanding shares of any one or more other classes or series of stock of the Corporation upon which like voting rights have been conferred and are exercisable (voting together as a class), shall have the right to elect two Directors to the Board of Directors of the Corporation at the Corporation’s next annual meeting of

stockholders, and so long as such default period continues, shall have the right to elect a successor to each of the two Directors so elected upon the expiration of their respective terms, such right to be exercised at the subsequent annual meeting or meetings at which the respective terms of such Directors expire. Any Director who shall have been so elected pursuant to this paragraph may be removed only for cause. If the office of any Director elected by the holders of Shares of Series A Preferred Stock pursuant to this paragraph becomes vacant for any reason, the remaining Director elected pursuant to this paragraph may choose a successor who shall hold office for the unexpired term in respect of which such vacancy occurred, and if the offices of both such Directors elected by the holders of Shares of Series A Preferred Stock pursuant to this paragraph become vacant for any reason, such vacancies may be filled for the unexpired term in respect of which such vacancy occurred only by the affirmative vote of the holders of the outstanding Shares of Series A Preferred Stock, together with the holders of the outstanding shares of any other class or series of stock upon which like voting rights have been conferred and are exercisable (voting together as a class).

(ii) The voting rights vested pursuant to paragraph (C)(i) hereof in the holders of the outstanding Shares of Series A Preferred Stock, together with the holders of outstanding shares of any one or more other classes or series of stock of the Corporation upon which like voting rights have been conferred and are exercisable (voting together as a class), may not be exercised at any annual meeting unless one-third of the outstanding shares of stock of the corporation upon which such voting rights have been conferred shall be present at such meeting in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Shares of Series A Preferred Stock of such rights. In connection with the election of Directors pursuant to paragraph (C)(i) hereof, each holder of Shares of Series A Preferred Stock shall be entitled to one vote for each one one-thousandth of a Share held (the holders of shares of any other class or series of preferred stock having like voting rights being entitled to such number of votes, if any, for each share of such stock held as may be granted to them).

(iii) During any default period, the holders of shares of Common Stock, and Shares of Series A Preferred Stock, and other classes or series of stock of the Corporation, if applicable, shall continue to be entitled to elect (voting together as a class) all the Directors other than the two Directors to be elected pursuant to paragraph (C)(i) hereof by the holders of the outstanding shares of Series A Preferred Stock, together with the holders of outstanding shares of any one or more other classes or series of stock of the Corporation upon which like voting rights have been conferred and are exercisable (voting together as a class).

(iv) Immediately upon the expiration of a default period, (x) the right of the holders of Shares of Series A Preferred Stock to elect Directors pursuant to paragraph (C)(i) hereof shall cease (subject to re-vesting in the event of each and every subsequent default of the character mentioned in paragraph (C)(i) above), and (y) the term of any Directors elected by the holders of Shares of Series A Preferred Stock pursuant to paragraph (C)(i) hereof shall terminate.

(D) Notwithstanding anything to the contrary contained herein, each Share of Series A Preferred Stock issued upon exercise of a Right which was originally received by the holder thereof in respect of a share of Nonvoting Common Stock of the Company shall have no voting rights other than such rights as the shares of Nonvoting Common Stock have under the Certificate, unless and until such share of Nonvoting Common Stock of the Company is converted into Common Stock in accordance with the Certificate (in which event it shall have the voting rights it would have had if it had originally been issued in respect of such Common Stock).

(E) Except as set forth herein, holders of Shares of Series A Preferred Stock shall have no special voting rights and their consents shall not be required (except to the extent

they are entitled to vote with holders of share of Common Stock as set forth herein) for taking any corporate action.

Section 4. Certain Restrictions. (A) Whenever quarterly dividends or other dividends or distributions payable on Shares of Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on outstanding Shares of Series A Preferred Stock shall have been paid in full, the Corporation shall not

(i) declare or pay dividends on, or make any other distributions on, any shares of Junior Stock;

(ii) declare or pay dividends on or make any other distributions on any shares of Parity Stock, except dividends paid ratably on Shares of Series A Preferred Stock and shares of all such Parity Stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of such Shares and all such shares are then entitled;

(iii) redeem or purchase or otherwise acquire for consideration shares of any Junior Stock, provided, however, that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such Junior Stock in exchange for shares of any Junior Stock; provided further, that the Corporation may repurchase shares of Common Stock owned by terminated employees of, or consultants to, the Corporation or its subsidiaries;

(iv) redeem or purchase or otherwise acquire for consideration any Shares of Series A Preferred Stock, or any Parity Stock except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates, and other relative rights and preferences of the respective series and classes, shall determine in good faith, will result in fair an equitable treatment among the respective series or classes.

(B) 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 paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.

Section 5. Reacquired Shares. Any Shares of Series A Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock, par value $0.001 per share, and may be reissued as part of a new series of Preferred Stock, subject to the conditions and restrictions on issuance set forth herein, in the Certificate, or in any other Certificate of

Designation creating a series of Preferred Stock, par value $0.001 per share, or any similar stock, or as otherwise restricted by law.

Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Corporation no distribution shall be made (i) to the holders of shares of Junior Stock unless the holders of Shares of Series A Preferred Stock shall have first received, subject to adjustment as hereinafter provided in paragraph (B), an amount in cash equal to the greater of either (a) $1.00 per Share plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not earned or declared, to the date of such payment, or (b) the amount equal to one thousand (1,000) times the aggregate per share amount to be distributed to holders of shares of Common Stock, or (ii) to the holders of shares of Parity Stock, unless simultaneously therewith distributions are made ratably on Shares of Series A Preferred Stock and all other shares of such Parity Stock in proportion to the total amounts to which the holders of Shares of Series A Preferred Stock are entitled under clause (i)(a) of this sentence and to which the holders of shares of such Parity Stock are entitled, in each case upon such liquidation, dissolution or winding up.

(B) In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine outstanding shares of Common Stock into a smaller number of shares, then in each such case the aggregate amount to which holders of Shares of Series A Preferred Stock were entitled immediately prior to such event pursuant to clause (i)(b) of paragraph (A) of this Section 6 shall be adjusted by multiplying such amount by a fraction the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination, or other transaction in which the shares of Common Stock are exchanged for or converted into other stock, securities, cash, and/or any other property, then in any such case Shares of Series A Preferred Stock shall at the same time be similarly exchanged for or converted into an amount per Share (subject to the provision for adjustment hereinafter set forth) equal to one thousand (1,000) times the aggregate amount of stock, securities, cash, and/or other property (payable in kind), as the case may be, into which or for which each share of Common Stock is converted or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the immediately preceding sentence with respect to the exchange or conversion of Shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 8. Conversion; Redemption. The Shares of Series A Preferred Stock shall not be convertible into any other class or series of capital stock of the Corporation, or redeemable.

Section 9. Ranking. Except as provided below, the Series A Preferred Stock shall rank junior to all other series of Preferred Stock, par value $0.001 per share, and to any other class of preferred stock that hereafter may be issued by the Corporation as to the payment of dividends and the distribution of assets, unless the terms of any such series or class shall provide otherwise. The Series A Preferred Stock shall rank prior, as to dividends and upon liquidation, dissolution, or winding up, to the Common Stock.

Section 10. Amendment. Except as set forth in Section 1 hereof, at any time that any Shares of Series A Preferred Stock are outstanding, the Certificate, including, without limitation, this Certificate of Designation shall not be amended, either directly or indirectly, or through merger or consolidation with another corporation or otherwise, in any manner that would alter or change the powers, preferences or special rights of the Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of at least two-thirds of the outstanding Shares of Series A Preferred Stock, voting separately as a class.

Section 11. Fractional Shares. The Series A Preferred Stock may be issued in fractions of one one-thousandth of a Share or other fractions of a share, which fractions shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions, and to have the benefit of all other rights of holders of Series A Preferred Stock.
