RIGHTS AGREEMENT

This Rights Agreement, dated as of September 25, 2007 (this “Agreement”), is made and entered into by and between Harsco Corporation, a Delaware corporation (the “Company”), and Mellon Investor Services LLC, as Rights Agent (the “Rights Agent”).

RECITALS

WHEREAS, on September 25, 2007, the Board of Directors of the Company (the “Board of Directors”) authorized and declared a dividend distribution of one right (a “Right”) for each share of Common Stock, par value $1.25 per share, of the Company (a “Common Share”) outstanding as of the Close of Business (as hereinafter defined) on October 9, 2007 (the “Record Date”), each Right initially representing the right to purchase one one-hundredth of a Preferred Share (as hereinafter defined), on the terms and subject to the conditions herein set forth, and further authorized and directed the issuance of one Right (subject to adjustment as provided herein) with respect to each Common Share issued or delivered by the Company (whether originally issued or delivered from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date (as hereinafter defined) and the Expiration Date (as hereinafter defined) or as provided in Section 22.

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

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

(a) “Acquiring Person” means any Person (other than the Company or any Related Person) who or which, together with all Affiliates and Associates of such Person, is or becomes the Beneficial Owner of 15% or more of the then-outstanding Common Shares; provided, however, that a Person will not be deemed to have become an Acquiring Person solely as a result of a reduction in the number of Common Shares outstanding unless and until such time as (A) such Person or any Affiliate or Associate of such Person thereafter becomes the Beneficial Owner of additional Common Shares representing 1% or more of the then-outstanding Common Shares, other than as a result of a stock dividend, stock split or similar transaction effected by the Company in which all holders of Common Shares are treated equally, or (B) any other Person who is the Beneficial Owner of Common Shares representing 1% or more of the then-outstanding Common Shares thereafter becomes an Affiliate or Associate of such Person. Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a Person who would otherwise be an “Acquiring Person” as defined pursuant to the foregoing provisions of this Section 1(a), has become such inadvertently, and such Person divests as promptly as practicable or agrees in writing with the Company to divest, a sufficient number of Common Shares so that such Person would no longer be an “Acquiring Person” as defined pursuant to the foregoing provisions of this Section 1(a), then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement.

(b) “Affiliate” and “Associate” will have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in effect

on the date of this Agreement, provided, however, that a Person will not be deemed to be the Affiliate or Associate of another Person solely because either or both Persons are or were Directors of the Company.

(i) which such Person or any of such Person’s Affiliates or Associates is deemed to beneficially own, directly or indirectly, within the meaning of Rule 13d-3 of the General Rules and Regulations under the Exchange Act as in effect on the date of this Agreement;

(ii) the beneficial ownership of which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (whether or not in writing), or upon the exercise of conversion rights, exchange rights, warrants, options or other rights (in each case, other than upon exercise or exchange of the Rights); provided, however, that a Person will not be deemed the Beneficial Owner of, or to Beneficially Own, securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange; or

(iii) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has or shares the right to vote or dispose of, including pursuant to any agreement, arrangement or understanding (whether or not in writing); or

(iv) of which any other Person is the Beneficial Owner, if such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (whether or not in writing) with such other Person (or any of such other Person’s Affiliates or Associates) with respect to acquiring, holding, voting or disposing of any securities of the Company;

provided, however, that a Person will not be deemed the Beneficial Owner of, or to Beneficially Own, any security (A) if such Person has the right to vote such security pursuant to an agreement, arrangement or understanding (whether or not in writing) which (1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations of the Exchange Act and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report), or (B) if such beneficial ownership arises solely as a result of such Person’s status as a “clearing agency,” as defined in Section 3(a)(23) of the Exchange Act; providedfurther, however, that nothing in this Section 1(c) will cause a Person engaged in business as an underwriter of securities to be the Beneficial Owner of, or to Beneficially Own, any securities acquired through such Person’s participation in good faith in an underwriting syndicate until the expiration of 40 calendar days after the date of such acquisition, or such later date as the Board of Directors of the Company may determine in any specific case.

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 of this Agreement, and the Rights Agent hereby accepts such appointment. The Company may from time to time act as co-Rights Agent or appoint such co-Rights Agents as it may deem necessary or desirable. Any actions which may be taken by the Rights Agent pursuant to the terms of this Agreement may be taken by any such co-Rights Agent. To the extent that any co-Rights Agent takes any action pursuant to this Agreement, such co-Rights Agent will be entitled to all of the rights and protections of, and subject to all of the applicable duties and obligations imposed upon, the Rights Agent pursuant to the terms of this Agreement. The Rights Agent shall have no duty to supervise, and in no event will be liable for, the acts or omissions of any such co-Rights Agent.

3. Issue of Right Certificates. (a) Until the Distribution Date, (i) the Rights will be evidenced by the certificates representing Common Shares registered in the names of the record holders thereof, which certificates representing Common Shares will also be deemed to be Right Certificates (or, if the Common Shares are uncertificated, by the registration of the associated Common Shares on the stock transfer books of the Company), (ii) the Rights will be transferable only in connection with the transfer of the underlying Common Shares, (iii) the transfer of any Common Shares in respect of which Rights have been issued will also constitute the transfer of the Rights associated with such Common Shares, and (iv) the interests of the holders of the Rights as such shall be deemed coincident with the interests of the holders of the Common Shares. Commencing as promptly as practicable after the Record Date, the Company will make available a copy of a Summary of Rights to Purchase Preferred Stock in substantially the form attached as Exhibit C to any holder of Rights who may request it from time to time prior to the Expiration Date.

(b) Rights will be issued by the Company in respect of all Common Shares (other than Common Shares issued upon the exercise or exchange of any Right) issued or delivered by the Company (whether originally issued or delivered from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date. Certificates evidencing such Common Shares will have stamped on, impressed on, printed on, written on, or otherwise affixed to them substantially the following legend or such similar legend as the Company may deem appropriate (but which does not affect the rights, duties or responsibilities of the Rights Agent) and as is not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or quotation system on which the Common Shares may from time to time be listed or quoted, or to conform to usage:

This Certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement between Harsco Corporation and Mellon Investor Services LLC, dated as of September 25, 2007 (the “Rights Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of Harsco Corporation. The Rights are not exercisable prior to the occurrence of certain events specified in the Rights Agreement. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be redeemed, may be exchanged, may expire, may be amended, or may be evidenced by separate certificates and no longer be evidenced by this Certificate. Harsco Corporation will mail to the holder of this

Certificate a copy of the Rights Agreement, as in effect on the date of mailing, without charge promptly after receipt of a written request therefor. Under certain circumstances as set forth in the Rights Agreement, Rights that are or were beneficially owned by an Acquiring Person or any Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement) may become null and void.

(c) Any Right Certificate issued pursuant to this Section 3 that represents Rights beneficially owned by an Acquiring Person or any Associate or Affiliate thereof and any Right Certificate issued at any time upon the transfer of any Rights to an Acquiring Person or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate and any Right Certificate issued pursuant to Section 6 or 11 hereof upon transfer, exchange, replacement or adjustment of any other Right Certificate referred to in this sentence, shall be subject to and may (to the extent feasible) contain substantially the following legend or such similar legend as the Company may deem appropriate (but which does not affect the rights, duties or responsibilities of the Rights Agent) and as is not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage:

The Rights represented by this Right Certificate are or were beneficially owned by a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). This Right Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 11(a)(ii) or Section 13 of the Rights Agreement.

(d) As promptly as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign and the Company will send or cause to be sent (and the Rights Agent will, if requested and provided with all necessary information, send), by first class, insured, postage prepaid mail, to each record holder of Common Shares as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, a Right Certificate evidencing one Right for each Common Share so held, subject to adjustment as provided herein. As of and after the Distribution Date, the Rights will be evidenced solely by such Right Certificates. The Company shall promptly notify the Rights Agent of the occurrence of the Distribution Date. 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.

(e) In the event that the Company purchases or otherwise acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares will be deemed canceled and retired so that the Company will not be entitled to exercise any Rights associated with the Common Shares so purchased or acquired.

4. Form of Right Certificates. The Right Certificates (and the form of election to purchase and the form of assignment to be printed on the reverse thereof) will be substantially in the form attached as Exhibit B with such changes and 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 or quotation system on which the Rights may from time to time be listed or quoted, or to conform to usage. Subject to the provisions of Section 22, the Right Certificates, whenever issued, on their face will entitle the holders thereof to purchase such number of one one-hundredths of a Preferred Share as are set forth therein at the Purchase Price set forth therein, but the Purchase Price, the number and kind of securities issuable upon exercise of each Right and the number of Rights outstanding will be subject to adjustment as provided herein.

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

(b) Following the Distribution Date and receipt by the Rights Agent of notice to that effect, the Rights Agent will keep or cause to be kept, at the its office designated for such purpose and at such other offices as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or any quotation system on which the Rights may from time to time be listed or quoted, books for registration and transfer of the Right Certificates issued hereunder. Such books will show the names and addresses of the respective holders of the Right Certificates, the number of Rights evidenced on its face by each of the Right Certificates and the date of each of the Right Certificates.

6. Transfer, Split Up, Combination and Exchange of Right Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. (a) Subject to the provisions of Sections 7(d) and 14, at any time after the Close of Business on the Distribution Date and prior to the Expiration Date, any Right Certificate or Right Certificates representing exercisable Rights may be transferred, split up, combined or exchanged for another Right Certificate or Right Certificates, entitling the registered holder to purchase a like number of one one-hundredths of a Preferred Share (or other securities, as the case may be) as the Right Certificate or Right Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to purchase.

Any registered holder desiring to transfer, split up, combine or exchange any such Right Certificate or Right Certificates must make such request in a writing delivered to the Rights Agent and must surrender the Right Certificate or Right Certificates to be transferred, split up, combined or exchanged at the office of the Rights Agent designated for such purpose. Thereupon or as promptly as practicable thereafter, subject to the provisions of Sections 7(d) and 14, the Company will prepare, execute and deliver to the Rights Agent, and the Rights Agent will countersign and deliver, a Right Certificate or Right Certificates, as the case may be, 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 to transfer, split up, combine or exchange any Right Certificates under this Section unless and until it is satisfied that all such taxes and/or governmental charges relating thereto 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, if requested by the Company, reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Right Certificate if mutilated, the Company will prepare, execute and deliver a new Right Certificate of like tenor to the Rights Agent and the Rights Agent will countersign and deliver such new Right Certificate to the registered holder in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

7. Exercise of Rights; Purchase Price; Expiration Date of Rights. (a) The registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date and prior to the Expiration Date, upon surrender of the Right Certificate, with the form of election to purchase on the reverse side thereof duly executed, to the Rights Agent at the office or offices of the Rights Agent designated for such purpose, together with payment in cash, in lawful money of the United States of America by certified check or bank draft payable to the order of the Company, equal to the sum of (i) the exercise price for the total number of securities as to which such surrendered Rights are exercised and (ii) an amount equal to any applicable transfer tax required to be paid by the holder of such Right Certificate in accordance with the provisions of Section 9(d).

(b) Upon receipt of a Right Certificate representing exercisable Rights with the form of election to purchase duly executed, accompanied by payment as described above, the Rights Agent will promptly (i) requisition from any transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent) certificates representing the number of one one-hundredths of a Preferred Share to be purchased or, in the case of uncertificated shares or other securities, requisition from any transfer agent therefor a notice setting forth such number of shares or other securities to be purchased for which registration will be made on the stock transfer books of the Company (and the Company hereby irrevocably authorizes and directs its transfer agent to comply with all such requests), or, if the Company elects to deposit Preferred Shares issuable upon exercise of the Rights hereunder with a depositary agent, requisition from

the depositary agent depositary receipts representing such number of one one-hundredths of a Preferred Share as are to be purchased (and the Company hereby irrevocably authorizes and directs such depositary agent to comply with all such requests), (ii) after receipt of such certificates (or notices or depositary receipts, as the case may be), 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, (iii) when appropriate, requisition from the Company or any transfer agent therefor (or make available, if the Rights Agent is the transfer agent) certificates representing the number of equivalent common shares (or, in the case of uncertificated shares, a notice of the number of equivalent common shares for which registration will be made on the stock transfer books of the Company) to be issued in lieu of the issuance of Common Shares in accordance with the provisions of Section 11(a)(iii), (iv) when appropriate, after receipt of such certificates or notices, 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, (v) when appropriate, requisition from the Company the amount of cash to be paid in lieu of the issuance of fractional shares in accordance with the provisions of Section 14 or in lieu of the issuance of Common Shares in accordance with the provisions of Section 11(a)(iii), (vi) when appropriate, after receipt, deliver such cash to or upon the order of the registered holder of such Right Certificate, and (vii) when appropriate, deliver any due bill or other instrument provided to the Rights Agent by the Company for delivery to the registered holder of such Right Certificate as provided by Section 11(l).

(c) In case the registered holder of any Right Certificate exercises less than all the Rights evidenced thereby, the Company will prepare, execute and deliver a new Right Certificate evidencing Rights equivalent to the Rights remaining unexercised and the Rights Agent will countersign and deliver such new Right Certificate to the registered holder of such Right Certificate or to his duly authorized assigns, subject to the provisions of Section 14.

(d) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company will be obligated to undertake any action with respect to any purported transfer, split up, combination or exchange of any Right Certificate pursuant to Section 6 or exercise of a Right Certificate as set forth in this Section 7 unless the registered holder of such Right Certificate has (i) completed and signed the certificate following the form of assignment or the form of election to purchase, as applicable, set forth on the reverse side of the Right Certificate surrendered for such transfer, split up, combination, exchange or exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company may reasonably request.

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

request of the Company, destroy such canceled Right Certificates, and in such case will deliver a certificate of destruction thereof to the Company.

9. Company Covenants Concerning Securities and Rights. The Company covenants and agrees that:

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

(b) So long as the Preferred Shares (and, following the occurrence of a Triggering Event, Common Shares and/or other securities) issuable upon the exercise of the Rights may be listed on a national securities exchange or quoted on a quotation system, it will endeavor to cause, from and after such time as the Rights become exercisable, all securities reserved for issuance upon the exercise of Rights to be listed on such exchange or quoted on such system, upon official notice of issuance upon such exercise.

(c) It will take all such action as may be necessary to ensure that all Preferred Shares (and, following the occurrence of a Triggering Event, Common Shares and/or other securities) delivered (or evidenced by registration on the stock transfer books of the Company) upon exercise of Rights, at the time of delivery of the certificates for (or registration of) such securities, will be (subject to payment of the Purchase Price) duly authorized, validly issued, fully paid and nonassessable securities.

(d) It will pay when due and payable any and all federal and state transfer taxes and charges that may be payable in respect of the issuance or delivery of the Right Certificates and of any certificates representing securities issued upon the exercise of Rights (or, if such securities are uncertificated, the registration of such securities on the stock transfer books of the Company); provided, however, that the Company will not be required to pay any transfer tax or charge which may be payable in respect of any transfer or delivery of Right Certificates to a person other than, or the issuance or delivery of certificates or depositary receipts representing (or the registration of) securities issued upon the exercise of Rights in a name other than that of, the registered holder of the Right Certificate evidencing Rights surrendered for exercise, or to issue or deliver any certificates, depositary receipts or notices representing securities issued upon the exercise of any Rights until any such tax or charge has 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 reasonable satisfaction that no such tax is due.

(e) It will use its best efforts (i) to file on an appropriate form, as soon as practicable following the later of the Share Acquisition Date and the Distribution Date, a registration statement under the Securities Act with respect to the securities issuable upon exercise of the Rights, (ii) to cause such registration statement to become effective as soon as practicable after such filing, and (iii) to cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities and (B) the Expiration Date. The Company will also take such action as may be appropriate under, or to ensure compliance with,

the applicable state securities or “blue sky” laws in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time after the date set forth in clause (i) of the first sentence of this Section 9(e), the exercisability of the Rights in order to prepare and file such registration statement and to permit it to become effective. Upon any such suspension, the Company will 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 addition, if the Company determines that a registration statement should be filed under the Securities Act or any state securities laws following the Distribution Date, the Company may temporarily suspend the exercisability of the Rights in each relevant jurisdiction until such time as a registration statement has been declared effective and, upon any such suspension, the Company will 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. Notwithstanding anything in this Agreement to the contrary, the Rights will not be exercisable in any jurisdiction if the requisite registration or qualification in such jurisdiction has not been effected or the exercise of the Rights is not permitted under applicable law. The Company will notify the Rights Agent and provide a copy of any public announcement it makes pursuant to this Section 9(e).

(f) Notwithstanding anything in this Agreement to the contrary, after the later of the Share Acquisition Date and the Distribution Date the Company will not take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will eliminate or otherwise diminish the benefits intended to be afforded by the Rights.

(g) In the event that the Company is obligated to issue other securities of the Company and/or pay cash pursuant to Section 11, 13, 14 or 24, it will make all arrangements necessary so that such other securities and/or cash are available for distribution by the Rights Agent, if and when appropriate under the terms of this Agreement.

10. Record Date. Each Person in whose name any certificate representing Preferred Shares (or Common Shares and/or other securities, as the case may be) is issued (or in which such securities are registered upon the stock transfer books of the Company) upon the exercise of Rights will for all purposes be deemed to have become the holder of record of the Preferred Shares (or Common Shares and/or other securities, as the case may be) represented thereby on, and such certificate (or registration) will be dated, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price and all applicable transfer taxes was made; provided, however, that if the date of such surrender and payment is a date upon which the transfer books of the Company for the Preferred Shares (or Common Shares and/or other securities, as the case may be) are closed, such Person will be deemed to have become the record holder of such securities on, and such certificate (or registration) will be dated, the next succeeding Business Day on which the transfer books of the Company for the Preferred Shares (or Common Shares and/or other securities, as the case may be) are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Right Certificate will not be entitled to any rights of a holder of any security for which the Rights are or may become exercisable, including, without limitation, the right to vote, to receive dividends

or other distributions, or to exercise any preemptive rights, and will not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

11. Adjustment of Purchase Price, Number and Kind of Securities or Number of Rights. The Purchase Price, the number and kind of securities issuable upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

(a) (i) In the event that the Company at any time after the Record Date (A) declares a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivides the outstanding Preferred Shares, (C) combines the outstanding Preferred Shares into a smaller number of Preferred Shares, or (D) issues any shares of its capital stock in a reclassification of the Preferred Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a), the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification and/or the number and/or kind of shares of capital stock issuable on such date upon exercise of a Right, will be proportionately adjusted so that the holder of any Right exercised after such time is entitled to receive upon payment of the Purchase Price then in effect the aggregate number and kind of shares of capital stock which, if such Right had been exercised immediately prior to such date and at a time when the transfer books of the Company for the Preferred Shares were open, the holder of such Right would have owned upon such exercise (and, in the case of a reclassification, would have retained after giving effect to such reclassification) and would have been entitled to receive by virtue of such dividend, subdivision, combination or reclassification; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock issuable upon exercise of one Right. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) or Section 13, the adjustment provided for in this Section 11(a)(i) will be in addition to, and will be made prior to, any adjustment required pursuant to Section 11(a)(ii) or Section 13.

(ii) Subject to the provisions of Section 24, if:

(A) any Person becomes an Acquiring Person; or

(B) any Acquiring Person or any Affiliate or Associate of any Acquiring Person, directly or indirectly, (1) merges into the Company or otherwise combines with the Company and the Company is the continuing or surviving corporation of such merger or combination (other than in a transaction subject to Section 13), (2) merges or otherwise combines with any Subsidiary of the Company, (3) in one or more transactions (otherwise than in connection with the exercise, exchange or conversion of securities exercisable or exchangeable for or convertible into shares of any class of capital stock of the Company or any of its Subsidiaries) transfers cash, securities or any other property to the Company or any of its Subsidiaries in exchange (in whole or in part) for shares of any class of capital stock of the Company or any of its

Subsidiaries or for securities exercisable or exchangeable for or convertible into shares of any class of capital stock of the Company or any of its Subsidiaries, or otherwise obtains from the Company or any of its Subsidiaries, with or without consideration, any additional shares of any class of capital stock of the Company or any of its Subsidiaries or securities exercisable or exchangeable for or convertible into shares of any class of capital stock of the Company or any of its Subsidiaries (otherwise than as part of a pro rata distribution to all holders of shares of any class of capital stock of the Company, or any of its Subsidiaries), (4) sells, purchases, leases, exchanges, mortgages, pledges, transfers or otherwise disposes (in one or more transactions) to, from, with or of, as the case may be, the Company or any of its Subsidiaries (otherwise than in a transaction subject to Section 13), any property, including securities, on terms and conditions less favorable to the Company than the Company would be able to obtain in an arm’s-length transaction with an unaffiliated third party, (5) receives any compensation from the Company or any of its Subsidiaries other than compensation as a director or a regular full-time employee, in either case at rates consistent with the Company’s (or its Subsidiaries’) past practices, or (6) receives the benefit, directly or indirectly (except proportionately as a stockholder), 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

(C) during such time as there is an Acquiring Person, there is any reclassification of securities of the Company (including any reverse stock split), or any 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 an Acquiring Person), other than a transaction subject to Section 13, which has the effect, directly or indirectly, of increasing by more than 1% the proportionate share of the outstanding shares of any class of equity securities of the Company or any of its Subsidiaries, or of securities exercisable or exchangeable for or convertible into equity securities of the Company or any of its Subsidiaries, of which an Acquiring Person, or any Affiliate or Associate of any Acquiring Person, is the Beneficial Owner;

then, and in each such case, from and after the latest of the Distribution Date, the Share Acquisition Date and the date of the occurrence of such Flip-in Event, proper provision will be made so that each holder of a Right, except as provided below, will thereafter have the right to receive, upon exercise thereof in accordance with the terms of this Agreement at an exercise price per Right equal to the product of the then-current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to the date of the occurrence of such Flip-in Event (or, if any other Flip-in Event shall have previously occurred, the product of the then-current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to the date of the first occurrence of a Flip-in Event), in lieu of Preferred Shares, such number of Common Shares as equals the result obtained by (x) multiplying the then-current Purchase Price by the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to the date of the occurrence of such Flip-in Event (or, if any other Flip-in Event shall have previously occurred, multiplying the then-current Purchase Price by the number of one one-hundredths of a Preferred Share for which a Right was exercisable

immediately prior to the date of the first occurrence of a Flip-in Event), and dividing that product by (y) 50% of the current per share market price of the Common Shares (determined pursuant to Section 11(d)) on the date of the occurrence of such Flip-in Event. Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of a Flip-in Event, any Rights that are Beneficially Owned by (A) any Acquiring Person (or any Affiliate or Associate of any Acquiring Person), (B) a transferee of any Acquiring Person (or any such Affiliate or Associate) who becomes a transferee after the occurrence of a Flip-in Event, or (C) a transferee of any Acquiring Person (or any such Affiliate or Associate) who became a transferee prior to or concurrently with the occurrence of a Flip-in Event pursuant to either (1) a transfer from an Acquiring Person to holders of its equity securities or to any Person with whom it has any continuing agreement, arrangement or understanding regarding the transferred Rights or (2) a transfer which the Directors of the Company have determined is part of a plan, arrangement or understanding which has the purpose or effect of avoiding the provisions of this Section 11(a)(ii), and subsequent transferees of any of such Persons, will be void without any further action and any holder of such Rights will thereafter have no rights whatsoever with respect to such Rights under any provision of this Agreement. The Company will use all reasonable efforts to ensure that the provisions of this Section 11(a)(ii) are complied with, but will have no liability to any holder of Right Certificates or any other Person as a result of its failure to make any determinations with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder. Upon the occurrence of a Flip-in Event, no Right Certificate that represents Rights that are or have become void pursuant to the provisions of this Section 11(a)(ii) will thereafter be issued pursuant to Section 3 or Section 6, and any Right Certificate delivered to the Rights Agent that represents Rights that are or have become void pursuant to the provisions of this Section 11(a)(ii) will be canceled. Upon the occurrence of a Flip-over Event, any Rights that shall not have been previously exercised pursuant to this Section 11(a)(ii) shall thereafter be exercisable only pursuant to Section 13 and not pursuant to this Section 11(a)(ii). Promptly upon the Company becoming aware of the identify of any such Acquiring Person, Associate or Affiliate or the nominee of any of the foregoing, the Company shall give the Rights Agent notice of the identity of any such Acquiring Person, 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 not be deemed to have any knowledge of the identity of any such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing unless and until it shall have received such notice or until such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing, has certified their status as such in writing to the Rights Agent.

(iii) Upon the occurrence of a Flip-in Event, if there are not sufficient Common Shares authorized but unissued or issued but not outstanding to permit the issuance of all the Common Shares issuable in accordance with Section 11(a)(ii) upon the exercise of a Right, the Board of Directors of the Company will use its best efforts promptly to authorize and, subject to the provisions of Section 9(e), make available for issuance additional Common Shares or other equity securities of the Company having equivalent voting rights

and an equivalent value (as determined in good faith by the Board of Directors of the Company) to the Common Shares (for purposes of this Section 11(a)(iii), “equivalent common shares”). In the event that equivalent common shares are so authorized, upon the exercise of a Right in accordance with the provisions of Section 7, the registered holder will be entitled to receive (A) Common Shares, to the extent any are available, and (B) a number of equivalent common shares, which the Board of Directors of the Company has determined in good faith to have a value equivalent to the excess of (x) the aggregate current per share market value on the date of the occurrence of the most recent Flip-in Event of all the Common Shares issuable in accordance with Section 11(a)(ii) upon the exercise of a Right (the “Exercise Value”) over (y) the aggregate current per share market value on the date of the occurrence of the most recent Flip-in Event of any Common Shares available for issuance upon the exercise of such Right; provided, however, that if at any time after 90 calendar days after the latest of the Share Acquisition Date, the Distribution Date and the date of the occurrence of the most recent Flip-in Event, there are not sufficient Common Shares and/or equivalent common shares available for issuance upon the exercise of a Right, then the Company will be obligated to deliver, upon the surrender of such Right and without requiring payment of the Purchase Price, Common Shares (to the extent available), equivalent common shares (to the extent available) and then cash (to the extent permitted by applicable law and any agreements or instruments to which the Company is a party in effect immediately prior to the Share Acquisition Date), which securities and cash have an aggregate value equal to the excess of (1) the Exercise Value over (2) the product of the then-current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to the date of the occurrence of the most recent Flip-in Event (or, if any other Flip-in Event shall have previously occurred, the product of the then-current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right would have been exercisable immediately prior to the date of the occurrence of such Flip-in Event if no other Flip-in Event had previously occurred). To the extent that any legal or contractual restrictions prevent the Company from paying the full amount of cash payable in accordance with the foregoing sentence, the Company will pay to holders of the Rights as to which such payments are being made all amounts which are not then restricted on a pro rata basis and will continue to make payments on a pro rata basis as promptly as funds become available until the full amount due to each such Rights holder has been paid.

(b) In the event that the Company fixes a record date for the issuance of rights, options or warrants to all holders of Preferred Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Preferred Shares (or securities having equivalent rights, privileges and preferences as the Preferred Shares (for purposes of this Section 11(b), “equivalent preferred shares”)) or securities convertible into Preferred Shares or equivalent preferred shares at a price per Preferred Share or equivalent preferred share (or having a conversion price per share, if a security convertible into Preferred Shares or equivalent preferred shares) less than the current per share market price of the Preferred Shares (determined pursuant to Section 11(d)) on such record date, the Purchase Price to be in effect after such record date will be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which is the number of Preferred Shares outstanding on such record date plus the number of Preferred Shares which

the aggregate offering price of the total number of Preferred Shares and/or equivalent preferred shares so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current per share market price and the denominator of which is the number of Preferred Shares outstanding on such record date plus the number of additional Preferred Shares and/or equivalent preferred shares to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock issuable upon exercise of one Right. In case such subscription price may be paid in a consideration part or all of which is in a form other than cash, the value of such consideration will be as determined in good faith by the Board of Directors of the Company, whose determination will be described in a statement filed with the Rights Agent. Preferred Shares owned by or held for the account of the Company will not be deemed outstanding for the purpose of any such computation. Such adjustment will be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, the Purchase Price will be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

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

(d) (i) For the purpose of any computation hereunder, the “current per share market price” of Common Shares on any date will be deemed to be the average of the daily closing prices per share of such Common Shares for the 30 consecutive Trading Days immediately prior to but not including such date; provided, however, that in the event that the current per share market price of the Common Shares is determined during a period following the announcement by the issuer of such Common Shares of (A) a dividend or distribution on such Common Shares payable in such Common Shares or securities convertible into such Common Shares (other than the Rights) or (B) any

subdivision, combination or reclassification of such Common Shares, and prior to but not including the expiration of 30 Trading Days after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the current per share market price will be appropriately adjusted to take into account ex-dividend trading or to reflect the current per share market price per Common Share equivalent. The closing price for each day will be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated quotation system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Common Shares are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated quotation system with respect to securities listed on the principal national securities exchange on which the Common Shares are listed or admitted to trading or, if the Common Shares are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by such market then in use, or, if on any such date the Common Shares are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Shares selected by the Board of Directors of the Company. If the Common Shares are not publicly held or not so listed or traded, or are not the subject of available bid and asked quotes, “current per share market price” will mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination will be described in a statement filed with the Rights Agent.

(ii) For the purpose of any computation hereunder, the “current per share market price” of the Preferred Shares will be determined in the same manner as set forth above for Common Shares in Section 11(d)(i), other than the last sentence thereof. If the current per share market price of the Preferred Shares cannot be determined in the manner provided above, the “current per share market price” of the Preferred Shares will be conclusively deemed to be an amount equal to the current per share market price of the Common Shares multiplied by one hundred (as such number may be appropriately adjusted to reflect events such as stock splits, stock dividends, recapitalizations or similar transactions relating to the Common Shares occurring after the date of this Agreement). If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, or the subject of available bid and asked quotes, “current per share market price” of the Preferred Shares will mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination will be described in a statement filed with the Rights Agent. For all purposes of this Agreement, the current per share market price of one one-hundredth of a Preferred Share will be equal to the current per share market price of one Preferred Share divided by one hundred.

(e) Except as set forth below, no adjustment in the Purchase Price will be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 11(e) are not required to be made will be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 will be made to the nearest cent or to the nearest one one-

millionth of a Preferred Share or one ten-thousandth of a Common Share or other security, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 will be made no later than the earlier of (i) three years from the date of the transaction which requires such adjustment and (ii) the Expiration Date.

(f) If as a result of an adjustment made pursuant to Section 11(a), the holder of any Right thereafter exercised becomes entitled to receive any securities of the Company other than Preferred Shares, thereafter the number and/or kind of such other securities so receivable upon exercise of any Right (and/or the Purchase Price in respect thereof) will be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Shares (and the Purchase Price in respect thereof) contained in this Section 11, and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares (and the Purchase Price in respect thereof) will apply on like terms to any such other securities (and the Purchase Price in respect thereof).

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder will evidence the right to purchase, at the adjusted Purchase Price, the number of one one-hundredths of a Preferred Share issuable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

(h) Unless the Company has exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price pursuant to Section 11(b) or Section 11(c), each Right outstanding immediately prior to the making of such adjustment will thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one one-hundredths of a Preferred Share (calculated to the nearest one one-millionth of a Preferred Share) obtained by (i) multiplying (x) the number of one one-hundredths of a Preferred Share issuable upon exercise of a Right immediately prior to such adjustment of the Purchase Price by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect, on or after the date of any adjustment of the Purchase Price, to adjust the number of Rights in substitution for any adjustment in the number of one one-hundredths of a Preferred Share issuable upon the exercise of a Right. Each of the Rights outstanding after such adjustment of the number of Rights will be exercisable for the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights will become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company will make a public announcement (with prompt notice thereof to the Rights Agent) of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. Such record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, will be at least 10 calendar days later than the date of the public announcement. If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company will, as promptly as practicable, cause to be distributed to holders of

record of Right Certificates on such record date Right Certificates evidencing, subject to the provisions of Section 14, the additional Rights to which such holders are entitled as a result of such adjustment, or, at the option of the Company, will cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof if required by the Company, new Right Certificates evidencing all the Rights to which such holders are entitled after such adjustment. Right Certificates so to be distributed will be issued, executed, and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and will be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

(j) Without respect to any adjustment or change in the Purchase Price and/or the number and/or kind of securities issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase Price and the number and kind of securities which were expressed in the initial Right Certificate issued hereunder.

(k) Before taking any action that would cause an adjustment reducing the Purchase Price below one one-hundredth of the then par value, if any, of the Preferred Shares or below the then par value, if any, of any other securities of the Company issuable upon exercise of the Rights, the Company will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable Preferred Shares or such other securities, as the case may be, at such adjusted Purchase Price.

(l) In any case in which this Section 11 otherwise requires that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer (with prompt notice thereof to the Rights Agent) until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Preferred Shares or other securities of the Company, if any, issuable upon such exercise over and above the number of Preferred Shares or other securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company delivers to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional Preferred Shares or other securities upon the occurrence of the event requiring such adjustment.

(m) Notwithstanding anything in this Agreement to the contrary, the Company will be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that in its good faith judgment the Board of Directors of the Company determines to be advisable in order that any (i) consolidation or subdivision of the Preferred Shares, (ii) issuance wholly for cash of Preferred Shares at less than the current per share market price therefor, (iii) issuance wholly for cash of Preferred Shares or securities which by their terms are convertible into or exchangeable for Preferred Shares, (iv) stock dividends, or (v) issuance of rights, options or warrants referred to in this Section 11, hereafter made by the Company to holders of its Preferred Shares is not taxable to such stockholders.

(n) Notwithstanding anything in this Agreement to the contrary, in the event that the Company at any time after the Record Date prior to the Distribution Date (i) pays a dividend on

the outstanding Common Shares payable in Common Shares, (ii) subdivides the outstanding Common Shares, (iii) combines the outstanding Common Shares into a smaller number of shares, or (iv) issues any shares of its capital stock in a reclassification of the outstanding Common Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), the number of Rights associated with each Common Share then outstanding, or issued or delivered thereafter but prior to the Distribution Date, will be proportionately adjusted so that the number of Rights thereafter associated with each Common Share following any such event equals the result obtained by multiplying the number of Rights associated with each Common Share immediately prior to such event by a fraction the numerator of which is the total number of Common Shares outstanding immediately prior to the occurrence of the event and the denominator of which is the total number of Common Shares outstanding immediately following the occurrence of such event. The adjustments provided for in this Section 11(n) will be made successively whenever such a dividend is paid or such a subdivision, combination or reclassification is effected.

12. Certificate of Adjusted Purchase Price or Number of Securities. Whenever an adjustment is made as provided in Section 11 or Section 13, the Company will promptly (a) prepare a certificate setting forth such adjustment or describing such event and a brief statement of the facts, computations and methodology accounting for such adjustment, (b) file with the Rights Agent and with each transfer agent for the Preferred Shares and the Common Shares a copy of such certificate, and (c) if such adjustment is made after the Distribution Date, mail a brief summary of such adjustment to each holder of a Right Certificate in accordance with Section 26. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and will have no duty or liability with respect to, and shall not be deemed to have knowledge of, any adjustment unless and until it shall have received such a certificate.

13. Consolidation, Merger or Sale or Transfer of Assets or Earning Power. (a) In the event that:

(i) at any time after a Person has become an Acquiring Person, the Company consolidates with, or merges with or into, any other Person and the Company is not the continuing or surviving corporation of such consolidation or merger; or

(ii) at any time after a Person has become an Acquiring Person, any Person consolidates with the Company, or merges with or into the Company, and the Company is the continuing or surviving corporation of such merger or consolidation and, in connection with such merger or consolidation, all or part of the Common Shares is changed into or exchanged for stock or other securities of any other Person or cash or any other property; or

(iii) at any time after a Person has become an Acquiring Person, the Company, directly or indirectly, sells or otherwise transfers (or one or more of its Subsidiaries sells or otherwise transfers), in one or more transactions, assets or earning power (including without limitation securities creating any obligation on the part of the Company and/or any of its Subsidiaries) representing in the aggregate 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;

then, and in each such case, proper provision will be made so that from and after the latest of the Share Acquisition Date, the Distribution Date and the date of the occurrence of such Flip-over Event (A) each holder of a Right thereafter has the right to receive, upon the exercise thereof in accordance with the terms of this Agreement at an exercise price per Right equal to the product of the then-current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to the Share Acquisition Date, such number of duly authorized, validly issued, fully paid, nonassessable and freely tradeable Common Shares of the Issuer, free and clear of any liens, encumbrances and other adverse claims and not subject to any rights of call or first refusal, as equals the result obtained by (x) multiplying the then-current Purchase Price by the number of one one-hundredths of a Preferred Share for which a Right is exercisable immediately prior to the Share Acquisition Date and dividing that product by (y) 50% of the current per share market price of the Common Shares of the Issuer (determined pursuant to Section 11(d)), on the date of the occurrence of such Flip-over Event; (B) the Issuer will thereafter be liable for, and will assume, by virtue of the occurrence of such Flip-over Event, all the obligations and duties of the Company pursuant to this Agreement; (C) the term “Company” will thereafter be deemed to refer to the Issuer; and (D) the Issuer will take such steps (including without limitation the reservation of a sufficient number of its Common Shares to permit the exercise of all outstanding Rights) in connection with such consummation as may be necessary to assure that the provisions hereof are thereafter applicable, as nearly as reasonably may be possible, in relation to its Common Shares thereafter deliverable upon the exercise of the Rights.

(b) For purposes of this Section 13, “Issuer” means (i) in the case of any Flip-over Event described in Sections 13(a)(i) or (ii) above, the Person that is the continuing, surviving, resulting or acquiring Person (including the Company as the continuing or surviving corporation of a transaction described in Section 13(a)(ii) above), and (ii) in the case of any Flip-over Event described in Section 13(a)(iii) above, the Person that is the party receiving the greatest portion of the assets or earning power (including without limitation securities creating any obligation on the part of the Company and/or any of its Subsidiaries) transferred pursuant to such transaction or transactions; provided, however, that, in any such case, (A) if (1) no class of equity security of such Person is, at the time of such merger, consolidation or transaction and has been continuously over the preceding 12-month period, registered pursuant to Section 12 of the Exchange Act, and (2) such Person is a Subsidiary, directly or indirectly, of another Person, a class of equity security of which is and has been so registered, the term “Issuer” means such other Person; and (B) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, a class of equity security of two or more of which are and have been so registered, the term “Issuer” means whichever of such Persons is the issuer of the equity security having the greatest aggregate market value. Notwithstanding the foregoing, if the Issuer in any of the Flip-over Events listed above is not a corporation or other legal entity having outstanding equity securities, then, and in each such case, (x) if the Issuer is directly or indirectly wholly owned by a corporation or other legal entity having outstanding equity securities, then all references to Common Shares of the Issuer will be deemed to be references to the Common Shares of the corporation or other legal entity having outstanding equity securities which ultimately controls

the Issuer, and (y) if there is no such corporation or other legal entity having outstanding equity securities, (I) proper provision will be made so that the Issuer creates or otherwise makes available for purposes of the exercise of the Rights in accordance with the terms of this Agreement, a kind or kinds of security or securities having a fair market value at least equal to the economic value of the Common Shares which each holder of a Right would have been entitled to receive if the Issuer had been a corporation or other legal entity having outstanding equity securities; and (II) all other provisions of this Agreement will apply to the issuer of such securities as if such securities were Common Shares.

(c) The Company will not consummate any Flip-over Event if, (i) at the time of or immediately after such Flip-over Event, there are or would be any rights, warrants, instruments or securities outstanding or any agreements or arrangements in effect which would eliminate or substantially diminish the benefits intended to be afforded by the Rights, (ii) prior to, simultaneously with or immediately after such Flip-over Event, the stockholders of the Person who constitutes, or would constitute, the Issuer for purposes of Section 13(a) shall have received a distribution of Rights previously owned by such Person or any of its Affiliates or Associates, or (iii) the form or nature of the organization of the Issuer would preclude or limit the exercisability of the Rights. In addition, the Company will not consummate any Flip-over Event unless the Issuer has a sufficient number of authorized Common Shares (or other securities as contemplated in Section 13(b) above) which have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this Section 13 and unless prior to such consummation the Company and the Issuer have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in subsections (a) and (b) of this Section 13 and further providing that as promptly as practicable after the consummation of any Flip-over Event, the Issuer will:

(A) prepare and file a registration statement under the Securities Act with respect to the Rights and the securities issuable upon exercise of the Rights on an appropriate form, and use its best efforts to cause such registration statement to (1) become effective as soon as practicable after such filing and (2) remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date;

(B) take all such action as may be appropriate under, or to ensure compliance with, the applicable state securities or “blue sky” laws in connection with the exercisability of the Rights; and

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

(d) The provisions of this Section 13 will similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a Flip-over Event occurs at any time after the occurrence of a Flip-in Event, except for Rights that have become void pursuant to Section 11(a)(ii), Rights that shall not have been previously exercised will cease to be exercisable in the manner provided in Section 11(a)(ii) and will thereafter be exercisable in the manner provided in Section 13(a).

14. Fractional Rights and Fractional Securities. (a) The Company will not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights. In lieu of such fractional Rights, the Company will pay as promptly as practicable to the registered holders of the Right Certificates with regard to which such fractional Rights otherwise would be issuable, an amount in cash equal to the same fraction of the current market value of one Right. For the purposes of this Section 14(a), the current market value of one Right is the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights otherwise would have been issuable. The closing price for any day is the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal quotation system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal quotation system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by such market then in use, or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company. If the Rights are not publicly held or are not so listed or traded, or are not the subject of available bid and asked quotes, the current market value of one Right will mean the fair value thereof as determined in good faith by the Board of Directors of the Company, whose determination will be described in a statement filed with the Rights Agent.

(b) The Company will not be required to issue fractions of Preferred Shares (other than fractions which are integral multiples of one one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares or to register fractional Preferred Shares on the stock transfer books of the Company (other than fractions which are integral multiples of one one-hundredth of a Preferred Share). Fractions of Preferred Shares in integral multiples of one one-hundredth of a Preferred Share may, at the election of the Company, be evidenced by depositary receipts pursuant to an appropriate agreement between the Company and a depositary selected by it, provided that such agreement provides that the holders of such depositary receipts have all the rights, privileges and preferences to which they are entitled as beneficial owners of the Preferred Shares represented by such depositary receipts. In lieu of fractional Preferred Shares that are not integral multiples of one one-hundredth of a Preferred Share, the Company may pay to any Person to whom or which such fractional Preferred Shares would otherwise be issuable an amount in cash equal to the same fraction of the current market value of one Preferred Share. For purposes of this Section 14(b), the current market value of one Preferred Share is the closing price of the Preferred Shares (as determined in the same manner as set forth for Common Shares in the second sentence of Section 11(d)(i)) for the Trading Day immediately prior to the date of such exercise; provided, however, that if the closing price of the Preferred Shares cannot be so determined, the closing price of the Preferred Shares for such Trading Day will be conclusively deemed to be an amount equal to the closing price of the Common Shares (determined pursuant to the second sentence of Section 11(d)(i)) for such Trading Day multiplied by one hundred (as such number may be appropriately adjusted to reflect events such as stock splits, stock dividends, recapitalizations or

similar transactions relating to the Common Shares occurring after the date of this Agreement); providedfurther, however, that if neither the Common Shares nor the Preferred Shares are publicly held or listed or admitted to trading on any national securities exchange, or the subject of available bid and asked quotes, the current market value of one Preferred Share will mean the fair value thereof as determined in good faith by the Board of Directors of the Company, whose determination will be described in a statement filed with the Rights Agent.

(c) Following the occurrence of a Triggering Event, the Company will not be required to issue fractions of Common Shares or other securities issuable upon exercise or exchange of the Rights or to distribute certificates which evidence any such fractional securities or to register any such fractional securities on the stock transfer books of the Company. In lieu of issuing any such fractional securities, the Company may pay to any Person to whom or which such fractional securities would otherwise be issuable an amount in cash equal to the same fraction of the current market value of one such security. For purposes of this Section 14(c), the current market value of one Common Share or other security issuable upon the exercise or exchange of Rights is the closing price thereof (as determined in the same manner as set forth for Common Shares in the second sentence of Section 11(d)(i)) for the Trading Day immediately prior to the date of such exercise or exchange; provided, however, that if neither the Common Shares nor any such other securities are publicly held or listed or admitted to trading on any national securities exchange, or the subject of available bid and asked quotes, the current market value of one Common Share or such other security will mean the fair value thereof as determined in good faith by the Board of Directors of the Company, whose determination will mean the fair value thereof as will be described in a statement filed with the Rights Agent.

(d) Whenever a payment for fractional Rights or fractional shares is to be made by the Rights Agent, the Company will (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 funds to the Rights Agent to make such payments. The Rights Agent shall be fully protected in relying upon such a certificate and will have no duty with respect to, and will 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 certificate and sufficient funds.

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

entitled to specific performance of the obligations under this Agreement, and injunctive relief against actual or threatened violations of the obligations of any Person subject to this Agreement.

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

(a) Prior to the Distribution Date, the Rights are transferable only in connection with the transfer of the Common Shares;

(b) After the Distribution Date, the Right Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer, and with the appropriate forms and certificates fully completed and executed;

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

(d) Such holder expressly waives any right to receive any fractional Rights and any fractional securities upon exercise or exchange of a Right, except as otherwise provided in Section 14.

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

17. Right Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Right Certificate will be entitled to vote, receive dividends, or be deemed for any purpose the holder of Preferred Shares or any other securities of the Company which may at any time be issuable upon the exercise of the Rights represented thereby, nor will anything contained herein or in any Right Certificate be construed to confer upon the holder of any Right Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of Directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 25), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions of this Agreement or exchanged pursuant to the provisions of Section 24.

18. Concerning the Rights Agent. (a) The Company will pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the preparation, delivery, amendment, administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company will also indemnify the Rights Agent for, and hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the reasonable fees and expenses of legal counsel), 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 anything done, suffered or omitted to be done by the Rights Agent in connection with the acceptance, administration, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly. The costs and expenses incurred in enforcing this right of indemnification will 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 will be authorized and protected and will incur no liability for, or in respect of any action taken, suffered, or omitted by it in connection with its acceptance and administration of this Agreement and the exercise and performance of its duties hereunder, in reliance upon any Right Certificate or certificate or other notice evidencing Preferred Shares or Common Shares or 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 or opinion of counsel as set forth in Section 20.

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 is a party, or any Person succeeding to the business of the Rights Agent or any successor Rights Agent, will 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. If at the time such successor Rights Agent succeeds 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 will have the full force provided in the Right Certificates and in this Agreement.

(b) If at any time the name of the Rights Agent changes and at such time any of the Right Certificates 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 have not 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 will have the full force provided in the Right Certificates and in this Agreement.

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

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company or an employee of the Rights Agent), and the advice or opinion of such counsel will 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 deems it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person and the determination of the current per share market price of any security) 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 President, any Vice President, the Secretary or the Treasurer of the Company and delivered to the Rights Agent, and such certificate will be full authorization to the Rights Agent for any action taken, suffered or omitted by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent will be liable hereunder 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). Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. 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.

(d) The Rights Agent will 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 will be deemed to have been made by the Company only.

(e) The Rights Agent will 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 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 will it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Right Certificate; nor will it be responsible any change in the exercisability of the Rights for any adjustment required under the provisions of Sections 11 or 13 (including any adjustment which results in Rights becoming void) or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after actual notice of any such adjustment after receipt of the certificate described in Section 12 upon which the Rights Agent may rely); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of stock or other securities to be issued pursuant to this Agreement or any Right Certificate or as to whether any shares of stock or other securities will, when issued, be duly authorized, validly issued, fully paid and nonassessable.

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

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

(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 Rights Agent under this Agreement. Nothing herein will 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 will not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company or any other Person resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith or willful misconduct in the selection and continued employment thereof (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). The Rights Agent will not be under any duty or responsibility to ensure compliance with any applicable federal or state securities laws in connection with the issuance, transfer or exchange of Right Certificates.

(j) If, with respect to any Right Certificate surrendered to the Rights Agent for exercise, transfer, split up, combination or exchange, either (i) the certificate attached to the form of assignment or form of election to purchase, as the case may be, has either not been completed or indicates an affirmative response to clause 1 or 2 thereof, or (ii) any other actual or suspected irregularity exists, the Rights Agent will not take any further action with respect to such requested exercise, transfer, split up, combination or exchange without first consulting with the Company, and will thereafter take further action with respect thereto only in accordance with the Company’s written instructions.

(k) No provision of this Agreement will 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 reasonably assured to it.

21. Change of Rights Agent. Except as otherwise provided by Section 31, the Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon 30 calendar days’ notice in writing mailed to the Company and to each transfer agent of the Preferred Shares or the Common Shares known to the Rights Agent by registered or certified mail, and to the holders of the Right Certificates by first class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30 calendar 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 Preferred Shares and the Common Shares by registered or certified mail, and to the holders of the Right Certificates by first class mail. If the Rights Agent resigns or is removed or otherwise becomes incapable of acting, the Company will appoint a successor to the Rights Agent. If the Company fails to make such appointment within a period of 30 calendar 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 will, with such notice, submit his Right Certificate for inspection by the Company), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, will be a Person organized and doing business under the laws of the United States or of any state of the United States so long as such Person is authorized to exercise stock transfer powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50 million. After appointment, the successor Rights Agent will 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 will deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of

the Preferred Shares or 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, will 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.

22. Issuance of New Right Certificates. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price per share and the number or kind of securities issuable upon exercise of the Rights made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale by the Company of Common Shares following the Distribution Date and prior to the Expiration Date, the Company (a) will, with respect to Common Shares so issued or sold pursuant to the exercise, exchange or conversion of securities (other than Rights) issued prior to the Distribution Date which are exercisable or exchangeable for, or convertible into Common Shares, and (b) may, in any other case, if deemed necessary, appropriate or desirable by the Board of Directors of the Company, issue Right Certificates representing an equivalent number of Rights as would have been issued in respect of such Common Shares if they had been issued or sold prior to the Distribution Date, as appropriately adjusted as provided herein as if they had been so issued or sold; provided, however, that (i) no such Right Certificate will be issued if, and to the extent that, in its good faith judgment the Board of Directors of the Company determines that the issuance of such Right Certificate could have a material adverse tax consequence to the Company or to the Person to whom or which such Right Certificate otherwise would be issued and (ii) no such Right Certificate will be issued if, and to the extent that, appropriate adjustment otherwise has been made in lieu of the issuance thereof.

23. Redemption. (a) Prior to the Expiration Date, the Board of Directors of the Company may, at its option, redeem all but not less than all of the then-outstanding Rights at the Redemption Price at any time prior to the Close of Business on the later of (i) the Distribution Date and (ii) Share Acquisition Date. Any such redemption will be effective immediately upon the action of the Board of Directors of the Company ordering the same, unless such action of the Board of Directors of the Company expressly provides that such redemption will be effective at a subsequent time or upon the occurrence or nonoccurrence of one or more specified events (in which case such redemption will be effective in accordance with the provisions of such action of the Board of Directors of the Company).

(b) Immediately upon the effectiveness of the redemption of the Rights as provided in Section 23(a), and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights will be to receive the Redemption Price, without interest thereon. Promptly after the effectiveness of the redemption of the Rights as provided in Section 23(a), the Company will publicly announce such redemption (with prompt notice thereof to the Rights Agent) and, within 10 calendar days thereafter, will give notice of such redemption to the holders of the then-outstanding Rights by mailing such notice to all such holders at their last addresses as they appear upon the registry books of the Company; provided, however, that the failure to give, or any defect in, any such notice will not

affect the validity of the redemption of the Rights. Any notice that is mailed in the manner herein provided will be deemed given, whether or not the holder receives the notice. The notice of redemption mailed to the holders of Rights will state the method by which the payment of the Redemption Price will be made. The Company may, at its option, pay the Redemption Price in cash, Common Shares (based upon the current per share market price of the Common Shares (determined pursuant to Section 11(d)) at the time of redemption), or any other form of consideration deemed appropriate by the Board of Directors of the Company (based upon the fair market value of such other consideration, determined by the Board of Directors of the Company in good faith) or any combination thereof. The Company may, at its option, combine the payment of the Redemption Price with any other payment being made concurrently to holders of Common Shares and, to the extent that any such other payment is discretionary, may reduce the amount thereof on account of the concurrent payment of the Redemption Price. If legal or contractual restrictions prevent the Company from paying the Redemption Price (in the form of consideration deemed appropriate by the Board of Directors) at the time of redemption, the Company will pay the Redemption Price, without interest, promptly after such time as the Company ceases to be so prevented from paying the Redemption Price.

24. Exchange. (a) The Board of Directors of the Company may, at its option, at any time after the later of the Share Acquisition Date and the Distribution Date, exchange all or part of the then-outstanding and exercisable Rights (which will not include Rights that have become void pursuant to the provisions of Section 11(a)(ii)) for Common Shares at an exchange ratio of one Common Share per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the Record Date (such exchange ratio being hereinafter referred to as the “Exchange Ratio”). Any such exchange will be effective immediately upon the action of the Board of Directors of the Company ordering the same, unless such action of the Board of Directors of the Company expressly provides that such exchange will be effective at a subsequent time or upon the occurrence or nonoccurrence of one or more specified events (in which case such exchange will be effective in accordance with the provisions of such action of the Board of Directors of the Company). Notwithstanding the foregoing, the Board of Directors of the Company will not be empowered to effect such exchange at any time after any Person (other than the Company or any Related Person), who or which, together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the then-outstanding Common Shares.

(b) Immediately upon the effectiveness of the exchange of any Rights as provided in Section 24(a), and without any further action and without any notice, the right to exercise such Rights will terminate and the only right with respect to such Rights thereafter of the holder of such Rights will be to receive that number of Common Shares equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. Promptly after the effectiveness of the exchange of any Rights as provided in Section 24(a), the Company will publicly announce such exchange (with prompt notice thereof to the Rights Agent) and, within 10 calendar days thereafter, will give notice of such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent; provided, however, that the failure to give, or any defect in, such notice will not affect the validity of such exchange. Any notice that is mailed in the manner herein provided will be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the

exchange of the Common Shares for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange will be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 11(a)(ii)) held by each holder of Rights.

AMENDED CERTIFICATE OF DESIGNATION,

PREFERENCES AND

RIGHTS OF SERIES A JUNIOR PARTICIPATING

CUMULATIVE PREFERRED STOCK

(1.25 PAR VALUE)

Harsco Corporation

Pursuant to Section 151 of the General Corporation Law

of the State of Delaware

We, Derek C. Hathaway, Chairman of the Board, and Paul C. Coppock, Secretary, of Harsco Corporation, a corporation organized and existing under the General Corporation Law of the State of Delaware, in accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

That pursuant to the authority conferred upon the Board of Directors by the Restated Certificate of Incorporation of the said Corporation, the said Board of Directors on September 29, 1987, adopted a resolution creating a series of 400,000 shares of Cumulative Preferred Stock designated as Series A Junior Participating Cumulative Preferred Stock with the preferences and rights as provided in the Certificate of Designation adopted by the Board; and on June 24, 1997, the said Board of Directors adopted a resolution amending the Certificate of Designation as follows:

RESOLVED, that pursuant to the authority vested in the Board of Directors of this Corporation in accordance with the provisions of its Restated Certificate of Incorporation, the Certificate of Designation adopted by the Board of Directors on September 29, 1987, is hereby amended effective September 28, 1997 as follows:

SECTION 1. DESIGNATION AND AMOUNT. The shares of such series shall be designated as “Series A Junior Participating Cumulative Preferred Stock” and the number of shares constituting such series shall be 750,000.

SECTION 2. DIVIDENDS AND DISTRIBUTIONS.

(A) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Series A Junior Participating Cumulative Preferred Stock with respect to dividends or distributions, the holders of shares of Series A Junior Participating Cumulative Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the fifteenth day of February, May, August and November in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”),

A–1

commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Junior Participating Cumulative Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $5.00 or (b) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value $1.25 per share, of the Corporation (the “Common Stock”) since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Junior Participating Cumulative Preferred Stock. In the event the Corporation shall at any time after September 28,1997 (the “Rights Declaration Date”) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a small number of shares, then in each such case the amount to which holders of shares of Series A Junior Participating Cumulative Preferred Stock were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) The corporation shall declare a dividend or distribution on the Series A Junior Participating Cumulative Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $5.00 per share on the Series A Junior Participating Cumulative Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Participating cumulative Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Junior Participating Cumulative Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for determination of holders of shares of Series A Junior Participating Cumulative Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Participating Cumulative Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Junior Participating Cumulative Preferred Stock

A–2

entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 45 days prior to the date fixed for the payment thereof.

SECTION 3. VOTING RIGHTS. In addition to the voting rights set forth in Article FOURTH of the Restated Certificate of Incorporation or otherwise required by law, the holders of shares of Series A Junior Participating Cumulative Preferred Stock shall have the following voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each share of Series A Junior Participating Cumulative Preferred Stock shall entitle the holder thereof to 100 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the number of votes per share to which holders of shares of Series A Junior Participating Cumulative Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein or by law, the holders of shares of Series A Junior Participating Cumulative Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation.

(C) (i) If at any time dividends on any Series A Junior Participating Cumulative Preferred Stock shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a “default period”) which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series A Junior Participating Cumulative Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, all holders of Cumulative Preferred Stock (including holders of the Series A Junior Participating Cumulative Preferred Stock) with dividends in arrears in an amount equal to six (6) quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two (2) Directors.

(ii) During any default period, such voting right of the holders of Series A Junior Participating Cumulative Preferred Stock may be exercised initially at a special meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of stockholders, and thereafter at annual meetings of Stockholders, provided that neither such voting right nor the right of the holders of any other series of Cumulative Preferred Stock, if any, to increase, in certain cases, the authorized number of Directors shall be exercised unless the holders of ten percent (10%) in number of shares of Cumulative Preferred Stock outstanding shall be present in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Cumulative Preferred Stock of such voting right. At any meeting at which the

A–3

holders of Cumulative Preferred Stock shall exercise such voting right initially during an existing default period, they shall have the right, voting as a class, to elect Directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two (2) Directors or, if such right is exercised at an annual meeting, to elect two (2) Directors. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the Cumulative Preferred Stock shall have the right to make such increase in the number of Directors as shall be necessary to permit the election by them of the required number. After the holders of the Cumulative Preferred Stock shall have exercised their right to elect Directors in any default period and during the continuance of such period, the number of Directors shall not be increased or decreased except by vote of the holders of Cumulative Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Junior Participating Cumulative Preferred Stock.

(iii) Unless the holders of Cumulative Preferred Stock shall, during an existing default period, have previously exercised their right to elect Directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Cumulative Preferred Stock outstanding, irrespective of series, may request, the calling of a special meeting of the holders of Cumulative Preferred Stock, which meeting shall thereupon be called by the President, a Vice-President or the Secretary of the Corporation. Notice of such meeting and of any annual meeting at which holders of Cumulative Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each holder of record of Cumulative Preferred Stock by mailing a copy of such notice to him at his last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or in default of the calling of such meeting within 60 days after such order or request, such meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Cumulative Preferred Stock outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the stockholders.

(iv) In any default period, the holders of Common Stock, and other classes of stock of the Corporation if applicable, shall continue to be entitled to elect the whole number of Directors until the holders of Cumulative Preferred Stock shall have exercised their right to elect two (2) Directors voting as a class, after the exercise of which right (x) the Directors so elected by the holders of Cumulative Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may (except as provided in paragraph (C)(ii) of this Section (3) be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the class of stock which elected the Director whose office shall have become vacant. References in this paragraph (C) to Directors elected by the holders of a particular class of stock shall include Directors elected by such Directors to fill vacancies as provided in clause (y) of the foregoing sentence.

A–4

(v) Immediately upon the expiration of a default period, (x) the right of the holders of Cumulative Preferred Stock as a class to elect Directors shall cease, (y) the term of any Directors elected by the holders of Cumulative Preferred Stock as a class shall terminate, and (z) the number of Directors shall be such number as may be provided for in the certificate of incorporation or by-laws irrespective of any increase made pursuant to the provisions of paragraph (C)(ii) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the certificate of incorporation or by-laws). Any vacancies in the Board of Directors effected by the provisions of clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining Directors.

(D) Except as set forth herein, holders of Series A Junior Participating Cumulative Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

SECTION 4. REACQUIRED SHARES. Any shares of Series A Junior Participating Cumulative Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Cumulative Preferred Stock and may be reissued as part of a new series of Cumulative Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

SECTION 5. LIQUIDATION, DISSOLUTION OR WINDING UP.

(A) Upon any voluntary liquidation, dissolution or winding up of the Corporation, no distribution shall be made to the holders of shares of stock ranking (either as to dividends or upon liquidation, dissolution or winding up) junior to the Series A Junior Participating Cumulative Preferred Stock unless, prior thereto, the holders of shares of Series A Junior Participating Cumulative Preferred Stock shall have received $150 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Junior Participating Cumulative Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing (i) the Series A Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in subparagraph C below to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in clause (ii), the “Adjustment Number”). Following the payment of the full amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Junior Participating Cumulative Preferred Stock and Common Stock, respectively, holders of Series A Junior Participating Cumulative Preferred Stock and holders of shares of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Cumulative Preferred Stock and Common Stock, on a per share basis, respectively.

A–5

(B) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of Cumulative Preferred Stock, if any, which rank on a parity with the Series A Junior Participating Cumulative Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock.

(C) In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

SECTION 6. CONSOLIDATION, MERGER, ETC. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Junior Participating Cumulative Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Junior Participating Cumulative Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

SECTION 7. NO REDEMPTION. The shares of Series A Junior Participating Cumulative Preferred Stock shall not be redeemable.

SECTION 8. RANKING. The Series A Junior Participating Cumulative Preferred Stock shall rank junior to all other series of the Corporation’s preferred stock as to the payment of dividends and the distribution of assets.

SECTION 9. AMENDMENT. The Restated Certificate of Incorporation of the Corporation shall not be further amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Junior Participating Cumulative Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a

A–6

majority or more of the outstanding shares of Series A Junior Participating Cumulative Preferred Stock, voting separately as a class.

SECTION 10. FRACTIONAL SHARES. Series A Junior Participating Cumulative Preferred Stock may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Participating Cumulative Preferred Stock.

IN WITNESS WHEREOF, we have executed and subscribed this Certificate and do affirm the foregoing as true under the penalties of perjury this ____ day of September, 1997.

EXHIBIT C

SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

On September 25, 2007, the Board of Directors of Harsco Corporation adopted a rights plan and declared a dividend of one preferred share purchase right for each outstanding share of Harsco Corporation’s Common Stock, par value $1.25 per share. The dividend is payable on October 9, 2007 to our stockholders of record on that date. The terms of the rights and the rights plan are set forth in a Rights Agreement, dated as of September 25, 2007, by and between Harsco Corporation and Mellon Investor Services LLC, as rights agent.

Our Board adopted the rights plan to protect our stockholders from coercive takeover practices or takeover bids that are inconsistent with their best interests. In general terms, the rights plan imposes a significant penalty upon any person or group that acquires 15% or more of our outstanding common stock without the prior approval of our Board. A person or group that acquires a percentage of our common stock in excess of that threshold is called an “acquiring person.” Any rights held by an acquiring person are void and may not be exercised.

This summary of rights provides a general description of the rights plan. Because it is only a summary, this description should be read together with the entire rights plan, which we incorporate in this summary by reference. We have filed the rights plan with the Securities and Exchange Commission as an exhibit to our registration statement on Form 8-A. Upon written request, we will provide a copy of the rights plan free of charge to any stockholder.

The Rights. Our Board of Directors authorized the issuance of one right per each outstanding share of our common stock on October 9, 2007. If the rights become exercisable, each right would allow its holder to purchase from us one one-hundredth of a share of our Series A Junior Participating Cumulative Preferred Stock for a purchase price of $230.00. Each fractional share of preferred stock would give the stockholder approximately the same dividend, voting and liquidation rights as does one share of our common stock. Prior to exercise, however, a right does not give its holder any dividend, voting or liquidation rights.

Exercisability. The rights will not be exercisable until the earlier of:

·	10 days after a public announcement by Harsco Corporation that a person or group has become an acquiring person; and

·	10 business days (or a later date determined by our Board) after a person or group begins a tender or exchange offer that, if completed, would result in that person or group becoming an acquiring person.

We refer to the date that the rights become exercisable as the “distribution date.” Until the distribution date, our common stock certificates will also evidence the rights and will contain a notation to that effect. Any transfer of shares of common stock prior to the distribution date will constitute a transfer of the associated rights. After the distribution date, the rights will separate from the common stock and be evidenced by right certificates, which we will mail to all holders of rights that have not become void.

C–1

Flip-in Event. After the distribution date, if a person or group already is or becomes an acquiring person, all holders of rights, except the acquiring person, may exercise their rights upon payment of the purchase price to purchase shares of our common stock (or other securities or assets as determined by the Board) with a market value of two times the purchase price.

Flip-over Event. After the distribution date, if a flip-in event has already occurred and Harsco Corporation is acquired in a merger or similar transaction, all holders of rights except the acquiring person may exercise their rights upon payment of the purchase price, to purchase shares of the acquiring corporation with a market value of two times the purchase price of the rights.

Rights may be exercised to purchase our preferred shares only after the distribution date occurs and prior to the occurrence of a flip-in event as described above. A distribution date resulting from the commencement of a tender offer or exchange offer described in the second bullet point above could precede the occurrence of a flip-in event, in which case the rights could be exercised to purchase our preferred shares. A distribution date resulting from any occurrence described in the first bullet point above would necessarily follow the occurrence of a flip-in event, in which case the rights could be exercised to purchase shares of common stock or other securities as described above.

Expiration. The rights will expire on October 9, 2017 unless earlier redeemed or exchanged.

Redemption. Our Board may redeem all (but not less than all) of the rights for a redemption price of $0.001 per right at any time before the later of the distribution date and the date of the first public announcement or disclosure by Harsco Corporation that a person or group has become an acquiring person. Once the rights are redeemed, the right to exercise rights will terminate, and the only right of the holders of rights will be to receive the redemption price. The redemption price will be adjusted if we declare a stock split or issue a stock dividend on our common stock.

Exchange. After the later of the distribution date and the date of the first public announcement by Harsco Corporation that a person or group has become an acquiring person, but before an acquiring person owns 50% or more of our outstanding common stock, our Board may exchange each right (other than rights that have become void) for one share of common stock or an equivalent security.

Anti-Dilution Provisions. Our Board may adjust the purchase price of the preferred shares, the number of preferred shares issuable and the number of outstanding rights to prevent dilution that may occur as a result of certain events, including among others, a stock dividend, a stock split or a reclassification of the preferred shares or our common stock. No adjustments to the purchase price of less than 1% will be made.

Amendments. Before the time rights cease to be redeemable, our Board may amend or supplement the rights plan without the consent of the holders of the rights, except that no

C–2

amendment may decrease the redemption price below $0.001 per right. At any time thereafter, our Board may amend or supplement the rights plan only to cure an ambiguity, to alter time period provisions, to correct inconsistent provisions or to make any additional changes to the rights plan, but only to the extent that those changes do not impair or adversely affect any rights holder and do not result in the rights again becoming redeemable. The limitations on our Board’s ability to amend the rights plan does not affect our Board’s power or ability to take any other action that is consistent with its fiduciary duties, including without limitation accelerating or extending the expiration date of the rights, making any amendment to the rights plan that is permitted by the rights plan or adopting a new rights plan with such terms as our Board determines in its sole discretion to be appropriate.
