This Rights Agreement (the “Agreement”) is made and entered into as of February 4, 2008, by and between CSK Auto Corporation, a Delaware corporation (the “Company”), and Mellon Investor Services LLC, a New Jersey limited liability company, as rights agent (the “Rights Agent”).

WHEREAS, the Board of Directors of the Company has authorized and declared a dividend of one share purchase right (a “Right”) for each Common Share (as hereinafter defined) of the Company outstanding on February 14, 2008 (the “Record Date”), each Right initially representing the right to purchase one Common Share (as hereinafter defined), upon the terms and subject to the conditions set forth herein, and has further authorized and directed the issuance of one Right with respect to each Common Share that shall become outstanding between the Record Date and the earliest of the Distribution Date, the Redemption Date or the Expiration Date (as such terms are hereinafter defined).

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

“Person” shall mean any individual, firm, partnership, corporation, limited liability company, association, group (as such term is used in Rule 13d-5 promulgated under the Exchange Act as in effect on the date hereof) or other entity, and shall include any successor (by merger or otherwise) of such entity.

“Triggering Date” shall mean the first date of public announcement (which, for purposes of this definition, shall include, without limitation, a report filed pursuant to Section 13(d) of the Exchange Act) by the Company or a Triggering Stockholder containing the facts by virtue of which a Person has become a Triggering Stockholder, or such earlier date that a majority of the members of the Board of Directors shall have become aware of the existence of a Triggering Stockholder.

(i) such Person represents to the Company that such Person inadvertently acquired such Beneficial Ownership;

(ii) such Person promptly, but in any event within 10 Business Days of receipt of a written request to do so duly issued on behalf of the Board of Directors, delivers to the Company a certificate signed by an authorized representative of such Person, satisfactory to the Board of Directors, representing that such Person has not acquired the Voting Shares with any purpose, or with the effect, of changing the control of the Company, or in connection with or as a participant in any transaction having that purpose or effect; and

In calculating the percentage of the outstanding Voting Shares that are Beneficially Owned by a Person for purposes of this definition, Voting Shares that are Beneficially Owned by such Person shall be deemed outstanding, and Voting Shares that are not Beneficially Owned by such Person and that are subject to issuance upon the exercise or conversion of outstanding conversion rights, exchange rights, rights, warrants or options shall not be deemed outstanding. Any determination made by the Board of Directors of the Company as to whether any Person is or is not a Triggering Stockholder shall be conclusive and binding upon all holders of Rights.

“Voting Share” shall mean (i) a Common Share and (ii) any other share of capital stock of the Company entitled to vote generally in the election of directors or entitled to vote together with the Common Shares in respect of any merger, consolidation, sale of all or substantially all of the Company’s assets, liquidation, dissolution or winding up of the Company. References in this Agreement to a percentage or portion of the outstanding Voting Shares shall be deemed a

reference to the percentage or portion of the total votes entitled to be cast by the holders of the outstanding Voting Shares.

Section 2. Appointment of Rights Agent. The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-Rights Agents as it may deem necessary or desirable upon ten (10) days’ prior written notice to the Rights Agent. The Rights Agent shall have no duty to supervise, and in no event be liable for, the acts or omissions of any such co-Rights Agent.

Section 3. Issuance of Right Certificates.

(a) “Distribution Date” shall mean the date, after the date hereof, that is the earliest of (i) the tenth Business Day (or such later day as shall be designated by the Board of Directors of the Company) following the date of the commencement of, or the first public announcement of the intent of any Person, other than an Exempt Person, to commence a tender offer or exchange offer, the consummation of which would cause any Person to become a Triggering Stockholder, (ii) the date of the first Section 11(a)(ii) Event or (iii) the date of the first Section 13(a) Event.

(b) Until the Distribution Date, (i) the Rights shall be represented by certificates for Common Shares (all of which certificates for Common Shares shall be deemed to be “Right Certificates”) and not by separate Right Certificates, (ii) the record holder of the Common Shares represented by each of such certificates shall be the record holder of the Rights represented thereby and (iii) the Rights shall be transferable only in connection with the transfer of Common Shares. Until the earliest of the Distribution Date, the Redemption Date or the Expiration Date, the surrender for transfer of such certificates for Common Shares shall also constitute the surrender for transfer of the Rights represented thereby. The Company shall promptly notify the Rights Agent in writing upon the occurrence of the Distribution Date and, if such notification is given orally, the Company shall confirm the same in writing on or prior to the Business Day next following. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Distribution Date has not occurred.

(c) As soon as practicable after the Distribution Date, and after notification by the Company, the Rights Agent shall (if provided with all the necessary information) send, at the expense of the Company, by first-class, postage-prepaid mail to each record holder of Common Shares, as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, a Right Certificate substantially in the form of Exhibit A hereto (a “Right Certificate”) representing one Right for each Common Share so held, subject to adjustment as necessary to give effect to any adjustments previously made to the number of Common Shares issuable upon exercise of a Right or adjustments previously made to the Exercise Price as provided herein. From and after the Distribution Date, the Rights shall be represented solely by such Right Certificates and may only be transferred by the transfer of such Right Certificates, and the holders of such Right Certificates, as listed in the records of the Company or any transfer agent or registrar for such Rights, shall be the record holders of such Rights.

(d) Certificates for Common Shares issued at any time after the Record Date and prior to the earliest of the Distribution Date, the Redemption Date or the Expiration Date, shall have impressed on, printed on, written on or otherwise affixed to them a legend in substantially the following form:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement dated as of February 4, 2008 by and between CSK Auto Corporation (the “Company”) and Mellon Investor Services LLC, as Rights Agent (the “Rights Agreement”), as amended to date, the terms and conditions of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances specified in the Rights Agreement, such Rights will be represented by separate certificates and will no longer be represented by this certificate. Under certain circumstances specified in the Rights Agreement, Rights beneficially owned by certain persons may become null and void. The Company will mail to the record holder of this certificate a copy of the Rights Agreement without charge promptly following receipt of a written request therefor. As described in the Rights Agreement, Rights Beneficially Owned by any Person who becomes a Triggering Stockholder or any Affiliate or Associate of a Triggering Stockholder (as such capitalized terms are defined in the Rights Agreement) shall become null and void.

(e) Certificates for Common Shares issued at any time on or after the Distribution Date and prior to the earlier of the Redemption Date or the Rights Expiration Date shall have impressed on, printed on, written on or otherwise affixed to them a legend in substantially the following form:

This certificate does not represent any Right issued pursuant to the terms of a Rights Agreement dated as of February 4, 2008 by and between CSK Auto Corporation and Mellon Investor Services LLC, as Rights Agent.

(f) In the event that at any time on or after the earlier of the date of the first Section 11(a)(ii) Event or the date of the first Section 13(a) Event and prior to the earlier of the Redemption Date or the Rights Expiration Date, the Company shall issue any Common Shares pursuant to the exercise of conversion rights, exchange rights, rights (other than Rights), warrants or options that shall have been issued or granted prior to the earlier of the date of the first Section 11(a)(ii) Event or the date of the first Section 13(a) Event, then, unless the Board of Directors of the Company shall have provided otherwise at the time of the issuance or grant of such conversion rights, exchange rights, rights (other than Rights), warrants or options, the Rights Agent shall, as soon as practicable after the date of such event, send by first-class, postage-prepaid mail to the record holder of such Common Shares, at the address of such holder as shown on the records of the Company, a Right Certificate substantially in the form of Exhibit A hereto representing one Right for each Common Share so issued.

(g) Notwithstanding the foregoing provisions of this Section 3, the Rights Agent shall not send any Right Certificate to any Triggering Stockholder or any of its Affiliates or Associates or to any Person if the Rights held by such Person are Beneficially Owned by a

Triggering Stockholder or any of its Affiliates or Associates. Any determination made by the Board of Directors of the Company as to whether any Common Shares are or were Beneficially Owned at any time by a Triggering Stockholder or an Affiliate or Associate of a Triggering Stockholder shall be conclusive and binding upon all holders of Rights.

Section 4. Form of Right Certificates. The Right Certificates and the form of assignment, including certificate, and the form of election to purchase, including certificate, printed on the reverse thereof, when, as and if issued, shall be substantially the same as Exhibit A hereto, and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate (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 with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange upon which the Rights or the securities of the Company issuable upon exercise of the Rights may from time to time be listed, or to conform to usage. Subject to Section 22 hereof, Right Certificates, whenever issued, that are issued in respect of Common Shares that were issued and outstanding as of the Close of Business on the Distribution Date, shall be dated as of the Distribution Date.

Section 5. Countersignature and Registration.

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

(b) Following the Distribution Date and receipt by the Rights Agent of notice to that effect, the Rights Agent shall keep or cause to be kept at its principal offices books for registration and transfer of the Right Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of Right Certificates, the number of Rights represented on its face by each Right Certificate and the date of each Right Certificate.

Section 6.

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

(a) Subject to the provisions of Sections 6(c), 7(d) and 14 hereof, at any time after the Close of Business on the Distribution Date, and so long as the Rights represented thereby remain

outstanding, any one or more Right Certificates may be transferred, split-up, combined or exchanged for one or more Right Certificates representing the same aggregate number of Rights as the Right Certificates surrendered. Any registered holder desiring to transfer, split up, combine or exchange one or more Right Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Right Certificates to be transferred, split up, combined or exchanged at the office of the Rights Agent with the form of assignment, including certificate, on the reverse side thereof completed and duly executed, with signature guaranteed. The Right Certificates are transferable only on the registry books of the Rights Agent. Thereupon, the Rights Agent shall countersign and deliver to the person entitled thereto one or more Right Certificates, as so requested. The Company or the Rights Agent may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Right Certificates. The Rights Agent shall have no duty or obligation under this Section unless and until it is satisfied that all such taxes and/or governmental charges have been paid.

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

(c) Notwithstanding anything to the contrary in this Section 6, the Rights Agent shall not countersign and deliver a Right Certificate to any Person if such Right Certificate represents, or would represent when held by such Person, Rights that had become or would become null and void pursuant to Section 7(d) hereof.

Section 7. Exercise of Rights.

(a) Until the Distribution Date, no Right may be exercised.

(b) Subject to Section 7(d) and (g) hereof and the other provisions of this Agreement, at any time after the Close of Business on the Distribution Date and prior to the Close of Business on the earlier of the Redemption Date or the Rights Expiration Date, the registered holder of any Right Certificate may exercise the Rights represented thereby in whole or in part upon surrender of such Right Certificate, with the form of election to purchase, including certificate, on the reverse side thereof completed and duly executed, with signature guaranteed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate Exercise Price for the number of Common Shares for each Right exercised. Upon the exercise of an exercisable Right and payment of the Exercise Price in accordance with the provisions of this Agreement, the holder of such Right shall be entitled to receive, subject to adjustment as provided herein, one Common Share (or, following the occurrence of a Section 11(a)(ii) Event or a Section 13(a) Event, Common Shares, cash, securities and/or other property).

(c) The “Exercise Price” for the exercise of each Right shall initially be $45.00 and shall be payable in lawful money of the United States of America in accordance with Section 7(f) hereof. The Exercise Price and the number of Common Shares (or, following the occurrence of a Section 11(a)(ii) Event or a Section 13(a) Event, Common Shares, cash, securities and/or other property) to be acquired upon exercise of a Right shall be subject to adjustment from time to time as provided in Sections 7(e), 11 and 13 hereof and the other provisions of this Agreement.

(d) Notwithstanding anything in this Agreement to the contrary, from and after the earlier of the date of the first Section 11(a)(ii) Event or the date of the first Section 13(a) Event, any Rights that are or were Beneficially Owned by a Triggering Stockholder or any Affiliate or Associate of a Triggering Stockholder at any time on or after the Distribution Date shall be null and void, and for all purposes of this Agreement such Rights shall thereafter be deemed not to be outstanding, and any holder of such Rights (whether or not such holder is a Triggering Stockholder or an Affiliate or Associate of a Triggering Stockholder) shall thereafter have no right to exercise such Rights.

(e) Prior to the Distribution Date, if the Board of Directors of the Company shall have determined that such action adequately protects the interests of the holders of Rights, the Company may, in its discretion, substitute for all or any portion of the Common Shares that would otherwise be issuable (after the Close of Business on the Distribution Date) upon the exercise of each Right and payment of the Exercise Price (i) cash, (ii) other equity or derivative securities of the Company, (iii) debt securities of the Company, (iv) other property or (v) any combination of the foregoing, in each case having an aggregate Current Market Price equal to the aggregate Current Market Price of the Common Shares for which substitution is made. Subject to Section 7(d) hereof, in the event that the Company takes any action pursuant to this Section 7(e), such action shall apply uniformly to all outstanding Rights.

(f) Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase, including certificate, completed and duly executed, with signature guaranteed, accompanied by payment of the Exercise Price for each Right to be exercised and an amount equal to any applicable tax or charge required to be paid by the holder of such Right Certificate in accordance with Section 9 hereof by certified check or cashier’s check payable to the order of the Company, the Rights Agent shall thereupon promptly (i) requisition from the transfer agent of the Common Shares (or, following the occurrence of a Section 11(a)(ii) Event or a Section 13(a) Event, Common Shares, cash, securities and/or other property) certificates for the number of Common Shares (or such other securities) to be purchased, and the Company hereby irrevocably authorizes such transfer agent to comply with all such requests, and/or, as provided in Section 14 hereof, requisition from the depositary agent described therein depositary receipts representing such number of Common Shares (or such other securities) as are to be purchased (in which case certificates for the Common Shares (or such other securities) represented by such receipts shall be deposited by the transfer agent with such depositary agent) and the Company hereby directs such depositary agent to comply with such request, (ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuance of fractional Common Shares (or such other securities) in accordance with Section 14 hereof, (iii) after receipt of such certificates, depositary receipts or cash, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or

names as may be designated by such holder and (iv) when appropriate, after receipt thereof, deliver such cash to or upon the order of the registered holder of such Right Certificate.

(g) Notwithstanding the foregoing provisions of this Section 7, the exercisability of the Rights shall be suspended for such period as shall reasonably be necessary for the Company to register and qualify under the Securities Act and any applicable securities law of any jurisdiction the Common Shares and/or other securities to be issued pursuant to the exercise of the Rights; provided, however, that nothing contained in this Section 7 shall relieve the Company of its obligations under Section 9(c) hereof.

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

(i) The Company shall give the Rights Agent written notice of the identity of any such Triggering Stockholder, Associate or Affiliate, or the nominee of any of the foregoing, and the Rights Agent may rely on such notice in carrying out its duties under this Agreement and shall be deemed not to have any knowledge of the identity of any such Triggering Stockholder, Associate or Affiliate, or the nominee of any of the foregoing unless and until it shall have received such notice.

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

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

Section 9. Reservation and Availability of Capital Stock.

(a) Subject to Sections 7(e) and 9(f) hereof, the Company shall cause to be reserved and kept available out of its authorized and unissued equity securities (or out of its authorized and issued equity securities held in its treasury), the number of such equity securities that will from time to time be sufficient to permit the exercise in full of all outstanding Rights (other than with respect to a Section 13(a) Event).

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

(c) If necessary to permit the issuance of securities upon exercise of the Rights, the Company shall use its best efforts, from and after the Distribution Date, to register and qualify such securities under the Securities Act, the Exchange Act and any other applicable securities laws and to keep such registration effective until the earlier of the Redemption Date or the Rights Expiration Date.

(d) The Company shall take all such action as may be necessary to ensure that all securities delivered upon exercise of the Rights shall, at the time of delivery of the certificates for such securities (subject to payment of the Exercise Price), be duly and validly authorized and issued and fully paid and nonassessable securities.

(e) The Company shall pay when due and payable any and all taxes and charges that may be payable in respect of the issuance or delivery of the Right Certificates or of any securities upon the exercise of Rights. The Company shall not, however, be required to pay any tax or charge that may be payable in respect of any transfer or delivery of a Right Certificate to a Person other than, or the issuance or delivery of a certificate for securities in respect of a name other than that of, the registered holder of the Right Certificate representing Rights surrendered for exercise, or to issue or deliver any certificate for securities upon the exercise of any Right until any such tax or charge shall have been paid (any such tax or charge being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Company’s or the Rights Agent’s satisfaction that no such tax or charge is due.

(f) With respect to the Common Shares and/or other securities issuable pursuant to Section 11(a)(ii) and (iii) hereof, the foregoing covenants shall be applicable only upon and following the occurrence of a Section 11(a)(ii) Event.

Section 10. Securities Record Date. Each Person in whose name any certificate for securities of the Company is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the securities represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate representing such Rights was duly surrendered and payment of the Exercise Price (and any applicable taxes or charges) was made; provided, however, that if the date of such surrender and payment is a date upon which the 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 securities transfer books of the Company are open.

Section 11. Adjustment of Exercise Price, Number of Shares Issuable Upon Exercise of Rights or Number of Rights. The Exercise Price, the number and kind of securities that may be purchased upon exercise of a 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 that the Company shall at any time after the Close of Business on the Record Date and prior to the Close of Business on the earlier of the Redemption Date or the Rights Expiration Date (A) declare or pay any dividend on the Common Shares payable in Common Shares or Voting Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding Common Shares into a smaller number of Common Shares or (D) issue Common Shares or other securities of the Company (other than those for which an adjustment is required under Section 11(b) hereof) 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) or in a reorganization of the Company, then, and upon each such event, the number and kind of Common Shares or other securities issuable upon the exercise of a Right on the date of such event shall be proportionately adjusted so that the holder of any Right exercised on or after such date shall be entitled to receive, upon the exercise thereof and payment of the Exercise Price, the aggregate number and kind of Common Shares or other securities or other property, as the case may be, that, if such Right had been exercised immediately prior to such date and at a time when such Right was exercisable and the transfer books of the Company were open, such holder would have owned upon such exercise and would have been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. 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 that:

(A) any Person, alone or together with its Affiliates and Associates, becomes a Triggering Stockholder after the date of this Agreement unless the

event causing “Triggering Stockholder” status to be triggered is a Permitted Offer; or

(B) a Triggering Stockholder (or any other Person who would be a “Triggering Stockholder” but for the operation of the first clause of subparagraph (d) of the definition of “Triggering Stockholder”) or any Associate or Affiliate thereof, at any time after the date of this Agreement, acquires Beneficial Ownership of, in the aggregate, a number of Voting Shares equal to 1% or more of the Voting Shares then outstanding, unless such acquisition is pursuant to a Permitted Offer;

(C) a Triggering Stockholder (or any other Person who would be a “Triggering Stockholder” but for the operation of the first clause of subparagraph (d) of the definition of “Triggering Stockholder”) or any Associate or Affiliate thereof, at any time after the date of this Agreement, directly or indirectly, (1) merges into the Company or otherwise combines with the Company or any Subsidiary of the Company and the Company or such Subsidiary is the continuing or surviving corporation of such merger or combination and the Common Shares of the Company shall remain outstanding and unchanged, (2) in one transaction or a series of transactions, transfers any assets to the Company or to any of its Subsidiaries in exchange (in whole or in part) for Common Shares, for shares of other equity securities of the Company, or for securities exercisable for or convertible into shares of equity securities of the Company (Common Shares or otherwise) or otherwise obtains from the Company, with or without consideration, any additional shares of such equity securities or securities exercisable for or convertible into shares of such equity securities (other than pursuant to a pro rata distribution to all holders of Common Shares), (3) sells, purchases, leases, exchanges, mortgages, pledges, transfers or otherwise acquires or disposes of, in one transaction or a series of transactions, to, from or with (as the case may be) the Company or any of its Subsidiaries, assets on terms and conditions less favorable to the Company than the Company would be able to obtain in arm’s-length negotiation with an unaffiliated third party, (4) sells, purchases, leases, exchanges, mortgages, pledges, transfers or otherwise acquires or disposes of in one transaction or a series of transactions, to, from or with (as the case may be) the Company or any of the Company’s Subsidiaries (other than incidental to the lines of business, if any, engaged in as of the date hereof between the Company and such Triggering Stockholder or Associate or Affiliate) assets having an aggregate fair market value of more than $5,000,000, (5) receives any compensation from the Company or any of the Company’s Subsidiaries other than compensation for full-time employment as a regular employee at rates in accordance with the Company’s (or its Subsidiaries’) past practices, or (6) receives the benefit, directly or indirectly (except proportionately as a stockholder and except if resulting from a requirement of law or governmental regulation), of any loans, advances, guarantees, pledges or other financial assistance or any tax credits or other tax advantage provided by the Company or any of its Subsidiaries; or

(D) during such time as there is a Triggering Stockholder, there is any reclassification of securities (including any reverse stock split), or recapitalization of the Company, or any merger or consolidation of the Company with any of its Subsidiaries or any other transaction or series of transactions involving the Company or any of its Subsidiaries (whether or not with or into or otherwise involving a Triggering Stockholder), which has the effect, directly or indirectly, of increasing by more than one percent (1%) the proportionate share of the outstanding shares of any class of equity securities of the Company or any of its Subsidiaries that are directly or indirectly beneficially owned by any Triggering Stockholder or any Associate or Affiliate thereof;

then, promptly following the occurrence of any event described in Sections 11(a)(ii)(A)-(D) hereof (each, a “Section 11(a)(ii) Event”), proper provision shall be made so that, except as provided in Section 7(d) hereof, each holder of a Right shall thereafter have the right to receive, upon the exercise thereof in accordance with the terms of this Agreement and payment of the then current Exercise Price, such number of Common Shares as shall equal the result obtained by (A) multiplying the then current Exercise Price by the then number of Common Shares for which a Right was exercisable immediately prior to such Section 11(a)(ii) Event (or, if the Distribution Date shall not have occurred prior to the date of such Section 11(a)(ii) Event, the number of Common Shares for which a Right would have been exercisable if the Distribution Date had occurred on the Business Day immediately preceding the date of such Section 11(a)(ii) Event), and (B) dividing that product by 50% of the Current Market Price of a Common Share on the date of occurrence of the relevant Section 11(a)(ii) Event (such number of shares being hereinafter referred to as the “Adjustment Shares”). Successive adjustments shall be made pursuant to this paragraph each time a Section 11(a)(ii) Event occurs; provided, however, that the Exercise Price and the number of Adjustment Shares shall be further adjusted as provided in this Agreement to reflect any events occurring after the date of such first occurrence; provided, further, that if the transaction that would otherwise give rise to the foregoing adjustment is also subject to the provisions of Section 13 hereof, then only the provisions of Section 13 shall apply and no adjustment shall be made pursuant to this Section 11(a)(ii).

(iii) In the event that on the date of a Section 11(a)(ii) Event the aggregate number of Common Shares that are authorized by the Company’s Certificate of Incorporation, as amended from time to time, but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is less than the aggregate number of Adjustment Shares thereafter issuable upon the exercise in full of the Rights in accordance with Section 11(a)(ii) hereof (the excess of such number of Adjustment Shares over and above such number of Common Shares being hereinafter referred to as the “Unavailable Adjustment Shares”), then, and upon each such event, the Company shall substitute for the pro rata portion of the Unavailable Adjustment Shares that would otherwise be issuable thereafter upon the exercise of each Right and payment of the Exercise Price (A) cash, (B) other equity or derivative securities of the Company (including, without limitation, shares of preferred stock of the Company or units of such shares or other securities having the same Current Market Price as one Common Share (a “Common Share Equivalent”)), (C) debt securities of the Company, (D) other property or

(E) any combination of the foregoing, in each case having an aggregate Current Market Price equal to the aggregate Current Market Price of the Unavailable Adjustment Shares for which substitution is made; provided, however, if the Company shall not have made adequate provision to deliver value pursuant to clauses (A) through (E) above within 30 days following the first occurrence of a Section 11(a)(ii) Event, then the Company shall be obligated to deliver cash for the pro rata portion of the Unavailable Adjustment Shares that would otherwise be issuable thereafter upon the exercise of such Right and payment of the Exercise Price. If the Board of Directors shall determine in good faith that it is likely that sufficient additional Common Shares could be authorized for issuance upon exercise in full of the Rights, the 30-day period set forth above may be extended to the extent necessary, but not more than 90 days after the first occurrence of a Section 11(a)(ii) Event, in order that the Company may seek stockholder approval for the authorization of such additional Common Shares (such period, as it may be extended, being referred to herein as the “Substitution Period”). To the extent that the Company determines that some action needs be taken pursuant to this Section 11(a)(iii), the Company (I) shall provide, subject to Section 7(d) hereof, that such action shall apply uniformly to all outstanding Rights and (II) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional Common Shares or to decide the appropriate form of distribution to be made pursuant to this Section 11(a)(iii) and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect, in each case with simultaneous written notice to the Rights Agent.

(b) In the event that the Company shall, at any time after the Close of Business on the Record Date and prior to the Close of Business on the earlier of the Redemption Date or the Rights Expiration Date, fix a record date for the issuance of rights, options or warrants to all holders of Common Shares entitling them initially to subscribe for or purchase Common Shares (or shares having the same rights, privileges and preferences as the Common Shares (“Common Share Equivalents”)) or securities convertible into Common Shares or Common Share Equivalents, at a price per Common Share or Common Share Equivalent (or having a conversion price per share, if a security convertible into Common Shares or Common Share Equivalents) less than the Current Market Price per Common Share on such record date, then, and upon each such event, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be equal to the sum of the number of Common Shares outstanding on such record date plus the number of Common Shares that the aggregate offering price of the total number of Common Shares and/or Common Share Equivalents to be so offered (and/or the aggregate initial conversion price of the convertible securities to be so offered) would purchase at such Current Market Price, and the denominator of which shall be equal to the number of Common Shares outstanding on such record date plus the number of additional Common Shares and/or Common Share Equivalents to be offered for subscription or purchase (or into which the convertible securities to be so offered are initially convertible); provided, however, that if such rights, options or warrants are not exercisable immediately upon issuance but become exercisable only upon the occurrence of a specified event or the passage of a specified period of time, then the adjustment to the Exercise Price shall be made and become effective only upon the

occurrence of such event or such passage of time, and such adjustment shall be made as if the record date for the issuance of such rights, options or warrants had been the Business Day immediately preceding the date upon which such rights, options or warrants became exercisable. Common Shares owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment to the Exercise Price 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 Exercise Price shall be adjusted to be the Exercise Price that would then be in effect if such record date had not been fixed.

(c) In the event that the Company shall, at any time after the Close of Business on the Record Date and prior to the Close of Business on the earlier of the Redemption Date or the Rights Expiration Date, fix a record date for the making of a distribution to all holders of the Common Shares (including any such distribution made in connection with a consolidation or merger in which the Company is the surviving corporation) of assets (other than a distribution for which an adjustment is required under Section 11(a)(i) or (b) hereof or a regular quarterly cash dividend), then the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be equal to the excess of the Current Market Price per Common Share on such record date over and above the fair market value of the portion of the securities or assets to be so distributed with respect to one Common Share, and the denominator of which shall be equal to such Current Market Price per Common Share. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such a distribution is not so made, the Exercise Price shall be adjusted to be the Exercise Price that would then be in effect if such record date had not been fixed.

(d) Reserved.

(e) No adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the then current Exercise Price; provided, however, that any adjustments that by reason of this Section 11(e) are not required to be made shall be cumulated and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one-thousandth of a Common Share.

(f) If, as a result of an adjustment made pursuant to Section 11(a) hereof, the holder of any Right shall, upon exercise thereof, be entitled to receive any securities of the Company other than Common Shares, and if an event occurs in respect of such securities that, if it were to occur in respect of Common Shares, would require an adjustment under this Section 11 in respect of Common Shares, then the number of such other securities so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Shares contained in this Section 11, and the other provisions of this Agreement with respect to Common Shares shall apply on like terms to any such other securities.

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Exercise Price hereunder shall represent the right to purchase, at the adjusted Exercise

Price, the number of Common Shares purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

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

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

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

(k) Before taking any action that would cause an adjustment reducing the Exercise Price below the then par value, if any, of the Common Shares issuable upon exercise of the Rights, the Company shall take any corporate action that may, in the advice or opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable Common Shares at such adjusted Exercise Price.

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

(m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such further adjustments in the number of Common Shares that may be purchased upon exercise of one Right, and such further adjustments in the Exercise Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that the Company in its sole discretion shall determine to be advisable in order that any (i) consolidation or subdivision of the Common Shares, (ii) issuance wholly for cash of any Common Shares at less than the Current Market Price thereof, (iii) issuance wholly for cash of Common Shares or securities that by their terms are convertible into or exchangeable for Common Shares, (iv) dividends on Common Shares payable in Common Shares or (v) issuance of rights, options or warrants referred to in Section 11(b) hereof, hereafter made by the Company to holders of its Common Shares shall not be taxable to such stockholders.

Section 12. Certificate of Adjusted Exercise Price or Number of Shares Issuable Upon Exercise of Rights. Whenever an adjustment is made or any event affecting the Rights or their exercisability (including without limitation an event which causes Rights to become null and void) as provided in Section 11 hereof, the Company shall promptly (a) prepare a certificate setting forth such adjustment or describing such event and a brief reasonably detailed statement of the facts, computations and methodology giving rise to such adjustment, (b) file with the Rights Agent and with each transfer agent for the securities issuable upon exercise of the Rights a copy of such certificate and (c) mail a brief summary thereof to each holder of Rights in accordance with Section 27 hereof. Notwithstanding the foregoing sentence, the failure of the Company to make such certification or to give such notice shall not affect the validity or the force and effect of such adjustment. Any adjustment to be made pursuant to Sections 11 or 13 hereof shall be effective as of the date of the event giving rise to such adjustment. 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 such an adjustment unless and until it shall have received such certificate.

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

(a) In the event (a “Section 13(a) Event”) that, at any time on or after the Triggering Date and prior to the earlier of the Redemption Date or the Rights Expiration Date, (1) the Company shall, directly or indirectly, consolidate with or merge with and into any other Person and the Company shall not be the continuing or surviving corporation in such consolidation or merger, (2) any Person shall, directly or indirectly, consolidate with or merge with and into the Company and the Company shall be the continuing or surviving corporation in such merger and, in connection with such merger, all or part of the Common Shares shall be changed into or exchanged for stock or other securities of any Person or cash or any other property, or (3) the Company and/or any one or more of its Subsidiaries shall, directly or indirectly, sell or otherwise transfer, in one or more transactions (other than transactions in the ordinary course of business), assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons other than the Company or one or more of its wholly-owned Subsidiaries (such Persons, together with the Persons described in clauses (1) and (2) above shall be collectively referred to in this Section as the “Surviving Person”), then, and in each such case, proper provision shall be made so that:

(i) except as provided in Section 7(d) hereof, each holder of a Right shall thereafter have the right to receive, upon the exercise thereof in accordance with the terms of this Agreement and payment of the then current Exercise Price, in lieu of the securities or other property otherwise purchasable upon such exercise, such number of validly authorized and issued, fully paid and nonassessable Common Shares of the Surviving Person (and if such Surviving Person has more than one class or series of Common Shares, such number of validly authorized and issued, fully paid and nonassessable Common Shares of each series or class) as shall be equal to a fraction, the numerator of which is:

(A) if a Section 11(a)(ii) Event has not occurred prior to such Section 13(a) Event, the product of the then current Exercise Price multiplied by the number of Common Shares purchasable upon the exercise of one Right immediately prior to the first Section 13(a) Event (or, if the Distribution Date shall not have occurred prior to the date of such Section 13(a) Event, the number of Common Shares that would have been so purchasable if the Distribution Date had occurred on the Business Day immediately preceding the date of such Section 13(a) Event), or

(B) if a Section 11(a)(ii) Event has occurred prior to such Section 13(a) Event, the product of the Exercise Price in effect immediately prior to such Section 11(a)(ii) Event multiplied by the number of Common Shares purchasable upon the exercise of one Right immediately prior to such Section 11(a)(ii) Event (or, if the Distribution Date shall not have occurred prior to the date of such Section 11(a)(ii) Event, the number of Common Shares that would have been so purchasable if the Distribution Date had occurred on the Business Day immediately preceding the date of such Section 11(a)(ii) Event),

and the denominator of which is 50% of the Current Market Price per Common Share of the Surviving Person on the date of consummation of such Section 13(a) Event;

(ii) the Surviving Person shall thereafter be liable for and shall assume, by virtue of such consolidation, merger, sale or transfer, all the obligations and duties of the Company pursuant to this Agreement;

(iii) the term “Company” shall thereafter be deemed to refer to the Surviving Person; and

(iv) the Surviving Person shall take such steps (including, but not limited to, the reservation of a sufficient number of its Common Shares in accordance with Section 9 hereof) in connection with such consummation as may be necessary to ensure that the provisions hereof shall thereafter be applicable to its Common Shares thereafter deliverable upon the exercise of Rights.

(b) Notwithstanding the foregoing, if the Section 13(a) Event is the sale or transfer in one or more transactions of assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole), but less than 100% thereof, then each Person acquiring all or a portion thereof shall assume the obligations of the Company as to a fraction of each of the Rights equal to the fraction of the assets of the Company and its Subsidiaries (taken as a whole) acquired by such Person, and the obligations of the Company as to the remaining fraction of each of the Rights shall continue to be the obligations of the Company.

(c) The Company shall not consummate a Section 13(a) Event unless prior thereto the Company and the Surviving Person shall have executed and delivered to the Rights Agent a supplemental agreement confirming that such Surviving Person shall, upon consummation of such Section 13(a) Event, assume this Agreement in accordance with Section 13 hereof, that all rights of first refusal or preemptive rights in respect of the issuance of Common Shares of such Surviving Person upon exercise of outstanding Rights have been waived and that such Section 13(a) Event shall not result in a default by such Surviving Person under this Agreement, and further providing that, as soon as practicable after the date of consummation of such Section 13(a) Event, such Surviving Person shall:

(i) prepare and file a registration statement under the Securities Act with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, use its best efforts to cause such registration statement to become effective as soon as practicable after such filing, use its best efforts to cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Rights Expiration Date, and similarly comply with all applicable state securities laws;

(ii) use its best efforts to list (or continue the listing of) the Rights and the Common Shares of the Surviving Person purchasable upon exercise of the Rights on a national securities exchange, or use its best efforts to cause the Rights and such Common Shares to meet the eligibility requirements for quotation on NASDAQ; and

(iii) deliver to holders of the Rights historical financial statements for such Surviving Person that comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act.

(d) In the event that at any time after the occurrence of a Section 11(a)(ii) Event some or all of the Rights shall not have been exercised pursuant to Section 11 hereof prior to the date of a Section 13(a) Event, such Rights shall thereafter be exercisable only in the manner described in Section 13(a) hereof. In the event that a Section 11(a)(ii) Event occurs on or after the date of a Section 13(a) Event, Rights shall not be exercisable pursuant to Section 11 hereof but shall instead be exercisable pursuant to, and only pursuant to, this Section 13.

(e) Notwithstanding anything in this Agreement to the contrary, the provisions of this Section 13 shall not apply to a transaction described in clauses (1) and (2) of Section 13(a) if (i) such transaction is consummated with a Person or Persons (or a wholly owned subsidiary of any such Person or Persons) who acquired Common Shares pursuant to a Permitted Offer, (ii) the price per Common Share offered in such transaction is not less than the price per Common Share paid to all holders of Common Shares whose shares were purchased pursuant to such Permitted Offer, and (iii) the form of consideration being offered to the remaining holders of Common Shares pursuant to such transaction is the same as the form of consideration paid pursuant to such Permitted Offer. Upon consummation of any such transaction contemplated by this Section 13(e), all Rights hereunder shall expire.

(f) The provisions of this Section 13 shall apply to each successive merger, consolidation, sale or other transfer constituting a Section 13(a) Event.

Section 14. Fractional Rights and Fractional Shares.

(a) The Company shall not be required to issue fractions of Rights or to distribute Right Certificates that represent fractional Rights. If the Company shall determine not to issue such fractional Rights, the Company shall pay to the registered holders of the Right Certificates with respect to which such fractional Rights would otherwise be issuable, at the time such fractional Rights would otherwise have been issued as provided herein, an amount in cash equal to the same fraction of the Current Market Price of a whole Right on the Business Day immediately prior to the date upon which such fractional Rights would otherwise have been issuable.

(b) The Company shall not be required to issue fractions of Common Shares upon exercise of Rights, or to distribute certificates that represent fractional Common Shares. Fractions of Common Shares may, at the election of the Company, be represented by depositary receipts, pursuant to an appropriate agreement between the Company and a depositary selected by it, provided that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of Common Shares. If the Company shall determine not to issue depositary receipts in lieu of Common Shares, the Company shall pay to the registered holders of Right Certificates with respect to which such fractional Common Shares would otherwise be issuable, at the time such Rights are exercised as provided herein, an amount in cash equal to the same fraction of the Current Market Price of a whole Common Share. For purposes of this Section 14(b), the Current

Market Price of a whole Common Share shall be the Closing Price per share for the Trading Day immediately prior to the date of such exercise.

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

(d) Whenever a payment for fractional Rights or fractional shares is to be made by the Rights Agent, the Company shall (i) promptly prepare and deliver to the Rights Agent a certificate setting forth in reasonable detail the facts related to such payments and the prices and/or formulas utilized in calculating such payments, and (ii) provide sufficient monies to the Rights Agent in the form of fully collected funds to make such payments. The Rights Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be deemed to have knowledge of any payment for fractional Rights or fractional shares under any Section of this Agreement relating to the payment of fractional Rights or fractional shares unless and until the Rights Agent shall have received such a certificate and sufficient monies.

Section 15. Rights of Action. All rights of action in respect of this Agreement, except the rights of action given to the Rights Agent herein, are vested in the respective registered holders of the Right Certificates and certificates for Common Shares representing Rights, and any registered holder of any Right Certificate or of such certificate for Common Shares, without the consent of the Rights Agent or of the holder of any other Right Certificate or any other certificate for Common Shares may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, such holder’s right to exercise the Rights represented by such Right Certificate or by such certificate for Common Shares in the manner provided in such 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 by the Company of this Agreement and shall be entitled to specific performance, and injunctive relief against actual or threatened violations by the Company, of the obligations of any Person under this Agreement.

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

(a) prior to the Distribution Date, the Rights shall be represented by certificates for Common Shares registered in the name of the holders of such Common Shares (which certificates for Common Shares shall also constitute Right Certificates), and each such Right shall be transferable only in connection with the transfer of such Common Shares;

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

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

Section 17. Right Holder and Right Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Right or Right Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the securities of the Company that may at any time be issuable upon the exercise of the Rights represented thereby, nor shall anything contained herein or in any Right Certificate be construed to confer upon the holder of any Right or Right Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, to give or withhold consent to any corporate action, to receive notice of meetings or other actions affecting stockholders (except as provided in Section 27 hereof), or to receive dividends or subscription rights, or otherwise, in each case until such Right or the Rights represented by such Right Certificate shall have been exercised in accordance with the provisions hereof.

Section 18. Concerning the Rights Agent.

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and disbursements and other disbursements incurred in the preparation, delivery, amendment ,administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense, incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction), 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. The costs and expenses of enforcing this right of indemnification shall also be paid by the Company. 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.

(b) The Rights Agent may conclusively rely upon and 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 or administration of this Agreement and the exercise and performance of its duties hereunder, in reliance upon any Right Certificate or certificate for Common Shares or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper person or persons, or otherwise upon the advice of its counsel as set forth in Section 20 hereof.

(c) Notwithstanding anything in this Agreement to the contrary, in no event shall the Rights Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage and regardless of the form of the action. Any liability of the Rights Agent under this Agreement will be limited to the amount of annual fees paid by the Company to 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 business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. If, at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and if at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in such Right Certificate and in this Agreement.

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

Section 20. Rights and Duties of Rights Agent. The Rights Agent undertakes to perform only the duties and obligations expressly imposed by this Agreement (and no implied duties or obligations shall be read into this Agreement against the Rights Agent) upon the following terms and conditions, by all of which the Company and the holders of Right Certificates, by their acceptance of the Rights, shall be bound:

(a) Before the Rights Agent acts or refrains from acting, it may consult with legal counsel (who may be legal counsel for the Company 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 and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it 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 be proved or established by the

Company prior to taking, suffering or omitting to take any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by any one of the Chairman of the Board, the Vice Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the 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 by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent shall be liable hereunder to the Company and any other Person only for its own gross negligence, bad faith or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction).

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

(e) The Rights Agent shall not have any liability for or be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Right Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including any Rights becoming null and void pursuant to Section 7(d) hereof) or any adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Sections 7, 11, 13 and 23 hereof, or the ascertaining of the existence of facts that would require any such change or adjustment (except with respect to the exercise of Rights represented by Right Certificates after actual notice that such change or adjustment is required); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares or other securities to be issued pursuant to this Agreement or any Right Certificate, or as to whether any Common Shares or other securities will, when issued, be validly authorized and issued, fully paid and nonassessable.

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

(g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Vice Chairman, the Chief Executive Officer, the President, any Vice President, the Chief Financial Officer, the Secretary or the 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 it shall not be liable for or in respect of any action taken, suffered or omitted to be taken by it in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions. The Rights Agent shall be fully authorized and protected in relying upon the most recent instructions received by any such officer. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken, suffered or omitted by the Rights Agent under this Agreement and the date on or after which such action shall be taken or suffered or such omission shall be effective. The Rights Agent shall not be liable for any action taken or suffered by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than ten Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless, prior to taking, suffering or omitting any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instructions from the Company in response to such application to the contrary.

(h) The Rights Agent and any stockholder, 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 the 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 or bad faith in the selection and continued employment thereof (which gross negligence or bad faith must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction).

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

(k) The Rights Agent shall not be required to take notice or be deemed to have notice of any fact, event or determination (including, without limitation, any dates or events defined in this Agreement or the designation of any Person as a Triggering Stockholder, Affiliate or Associate) under this Agreement unless and until the Rights Agent shall be specifically notified in writing by the Company of such fact, event or determination.

(l) If, with respect to any Right 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, the Rights Agent shall not take any further

action with respect to such requested exercise or transfer without first consulting with the Company.

Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon 30-days’ notice in writing mailed to the Company and to each transfer agent of the Common Shares known to the Rights Agent by registered or certified mail, and, at the expense of the Company to the holders of the Right Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30-days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Shares by registered or certified mail, and to the holders of the Right Certificates by first-class mail. In the event the transfer agency relationship in effect between the Company and the Rights Agent terminates, the Rights Agent will be deemed to resign automatically on the effective date of such termination, and any required notice will be sent by the Company. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting as such, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall, with such notice, submit such holder’s Right Certificate for inspection by the Company), then the Company shall become the Rights Agent and the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a Person organized and doing business under the laws of the United States (or of any other state of the United States), in good standing, that is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by federal or state authority and that has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000. 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 of this Agreement and so that the successor Rights Agent may appropriately act as Rights Agent hereunder. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares, and mail a notice thereof in writing to the registered holders of the Right Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

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

Section 23. Redemption of Rights.

(a) Until the earliest of the date that is (i) the tenth Business Day after the Triggering Date (or, if the tenth Business Day after the Triggering Date occurs before the Record Date, the Close of Business on the Record Date) or (ii) the Rights Expiration Date, the Board of Directors of the Company may, at its option, authorize and direct the redemption of all, but not less than all, of the then outstanding Rights at a redemption price of $0.001 per Right, as such redemption price shall be appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (the “Redemption Price”), and the Company shall so redeem the Rights. If, following the occurrence of a Triggering Date and following the expiration of the right of redemption hereunder but prior to any Section 11(a)(ii) Event or Section 13(a) Event, (A) a Person who is a Triggering Stockholder shall have transferred or otherwise disposed of a number of Voting Shares in one transaction or series of transactions, not directly or indirectly involving the Company or any of its Subsidiaries, that did not result in the occurrence of a Section 11(a)(ii) Event or a Section 13(a) Event such that such Person is thereafter a Beneficial Owner of 10% or less of the Voting Shares then outstanding, (B) there are no other Persons, immediately following the occurrence of the event described in clause (A), who are Triggering Stockholders and (C) the Board of Directors shall so approve, then the right of redemption shall be reinstated and thereafter be subject to the provisions of this Section 23. Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event or a Section 13(a) Event until such time as the Company’s right of redemption hereunder has expired. Notwithstanding the foregoing, the Rights shall become nonredeemable on and following any merger to which the Company is a party and that has not been approved by stockholders at an annual or special meeting of the Company, if within the period of 30 days prior to such a merger a Section 11(a)(ii) Event or a Section 13(a) Event shall have occurred.

(b) Immediately upon the action of the Board of Directors authorizing and directing the redemption of the Rights pursuant to subsection (a) of this Section 23, or at such time and date thereafter as specified, and without any further action and without any notice, the right to exercise Rights shall terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price. Within ten (10) Business Days after the date of such action, the Company shall give notice of such redemption (with prompt written notice thereof to the Rights Agent) to the holders of Rights by mailing such notice to all holders of Rights at their last addresses as they appear upon the registry books of the Rights Agent or, if 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 such notice, but neither the failure to give any such notice nor any defect therein shall affect the legality or validity of such redemption. Each such notice of redemption shall state the method by which the payment of the Redemption Price will be made. Neither the Company nor any of its Affiliates or Associates may, directly or indirectly, redeem, acquire or purchase for value any Rights in any manner other than that specifically set forth in Section 24 hereof or in this Section 23, or in connection with the purchase of Common Shares prior to the earlier of the date of the first Section 11(a)(ii) Event or the date of the first Section 13(a) Event.

(c) The Company may, at its option, pay the Redemption Price in cash, Common Shares, other equity securities of the Company, debt securities of the Company, other property or any combination of the foregoing, in each case having an aggregate Current Market Price on the Redemption Date equal to the Redemption Price.

Section 24. Exchange of Rights.

(a) At any time during the period of 180 days after a Section 11(a)(ii) Event, the Board of Directors of the Company may, at its option, authorize and direct the exchange of all, but not less than all, of the then outstanding Rights for Common Shares, other equity securities, debt or derivative securities of the Company, other property, or any combination of the foregoing, in each case having an aggregate Current Market Price equal to the result obtained by (i) multiplying the Current Market Price per Common Share on the record date for such exchange by the number of Common Shares for which a Right is exercisable on such record date and (ii) subtracting from such product the Exercise Price on such Record Date (the “Exchange Ratio”), and the Company shall so exchange the Rights.

(b) Immediately upon the action of the Board of Directors of the Company authorizing and directing the exchange of the Rights pursuant to subsection (a) of this Section 24, or at such time and date thereafter as it may specify, and without any further action and without any notice, the right to exercise Rights shall terminate and the only right thereafter of the holders of Rights shall be to receive the securities described in Section 24(a) in accordance with the Exchange Ratio. Within ten (10) Business Days after the date of such action, the Company shall give notice of such exchange (with prompt written notice thereof to the Rights Agent) to the holders of Rights by mailing such notice to all holders of Rights at their last addresses as they appear upon the registry books of the Rights Agent or, if 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 such notice, but neither the failure to give any such notice nor any defect therein shall affect the legality or validity of such exchange. Each such notice of exchange shall state the method by which the Rights will be exchanged.

(c) Notwithstanding the foregoing, in the event that the aggregate number of Common Shares that are authorized by the Company’s Certificate of Incorporation, as amended from time to time, but not outstanding or reserved for issuance for purposes other than upon exercise or exchange of the Rights is less than the aggregate number of Common Shares issuable upon the exchange of the Rights in accordance with this Section 24 (the excess of such number of authorized Common Shares over and above such number of issuable Common Shares being hereinafter referred to as the “Unavailable Exchange Shares”), then the Company shall substitute for the pro rata portion of the Unavailable Exchange Shares that would otherwise be issuable upon the exchange of the Rights in accordance with this Section 24 (i) cash, (ii) other equity securities of the Company (including, without limitation, Common Share Equivalents), (iii) debt securities of the Company, (iv) other property or (v) any combination of the foregoing, in each case having an aggregate Current Market Price equal to the aggregate Current Market Price of the Unavailable Exchange Shares for which substitution is made. Subject to Section 7(d) hereof, in the event that the Company takes any action pursuant to this Section 24, such action shall apply uniformly to all outstanding Rights.

Section 25. Independent Director Review.

Should the Expiration Date be extended by the stockholders of the Company beyond February 3, 2009, a committee of the Board of Directors of the Company comprised entirely of

independent directors shall evaluate the Agreement at least once prior to the date that is three years from the date of this Agreement, and to the extent not terminated prior to such date, at least once every three years thereafter, to determine whether this Agreement continues to be in the best interests of the stockholders of the Company or, rather, if the Rights should be redeemed.

Section 26. Notice of Certain Events.

(a) In the event that the Company shall propose (i) to declare or pay any dividend on or make any distribution with respect to its Common Shares (other than a regular quarterly cash dividend), (ii) to offer to the holders of its Common Shares options, rights or warrants to subscribe for or to purchase any additional shares thereof or shares of stock of any class or any other securities, rights or options, (iii) to effect any reclassification of its Common Shares (other than a reclassification involving only the subdivision of outstanding shares), (iv) to effect any consolidation or merger with or into, 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, or (v) to effect the liquidation, dissolution or winding up of the Company, then and in each such case, the Company shall give to the Rights Agent and each holder of a Right Certificate, in accordance with Section 28 hereof, a notice of such proposed action that shall specify the record date for the purpose of such dividend or distribution, or the date upon 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 record of the Common Shares, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least 20 days prior to the record date for determining holders of the Common Shares for purposes of such action, and in the case of any such other action, at least 20 days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Common Shares, whichever date shall be the earlier. The failure to give the notice required by this Section 27 or any defect therein shall not affect the legality or validity of the action taken by the Company or the vote upon any such action.

(b) Upon the occurrence of each Section 11(a)(ii) Event and each Section 13(a) Event, the Company shall as soon as practicable thereafter give to the Rights Agent and to each holder of a Right Certificate, in accordance with Section 28 hereof, a notice of the occurrence of such event, specifying the event and the consequences of the event to holders of Rights under Sections 11 and 13 hereof.

Section 27. Notices. Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Right Certificate to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows:
