RIGHTS AGREEMENT

This Agreement, dated as of July 11, 2007, between AAR CORP., a Delaware corporation (the “Company”), and Computershare Trust Company, N.A., a national banking association (the “Rights Agent”).

W I T N E S S E T H

WHEREAS, the Board of Directors of the Company has authorized and declared a dividend distribution (the “Distribution”) of one Right (as hereinafter defined) for each share of Common Stock, $1.00 par value, of the Company outstanding at the close of business on August 6, 2007 (the “Record Date”) and has further authorized the issuance of one Right in respect of each share of Common Stock of the Company issued between such date and the earlier of the Distribution Date or the Expiration Date (as such terms are hereinafter defined), each Right initially representing the right to purchase one share of Common Stock of the Company (the “Rights”), all upon the terms, with the adjustments and subject to the conditions hereinafter set forth;

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

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

(a) “Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, without prior approval of the Company shall be the Beneficial Owner of a Substantial Block or who was such a Beneficial Owner at any time after the date hereof, whether or not such Person continues to be the Beneficial Owner of a Substantial Block, but shall not include the Company, any Subsidiary of or other Person controlled by the Company, any employee benefit plan of the Company or of any Subsidiary of the Company or any Person appointed as trustee by the Company or such Subsidiary pursuant to the terms of any such plan in that Person’s capacity as trustee. Notwithstanding the foregoing, no Person shall become an “Acquiring Person” (i) as a result of the acquisition of shares of Common Stock by the Company which, by reducing the number of shares of Common Stock outstanding, increases the proportional number of shares beneficially owned by such Person together with all Affiliates and Associates of such Person; provided however, that if (1) a Person would become an Acquiring Person (but for the operation of this subclause (i)) as a result of the acquisition of shares of Common Stock by the Company, and (2) after such share acquisition by the Company, such Person, or an Affiliate or Associate of such Person, becomes the Beneficial Owner of any additional shares of Common Stock, then such Person shall be deemed an Acquiring Person; or (ii) if the Board of Directors determines that such Person became an Acquiring Person inadvertently, and such Person promptly divests itself of a sufficient number of shares of Common Stock so that such Person is the Beneficial Owner of such number of shares of Common Stock so that such Person no longer would be an Acquiring Person.

(b) “Affiliate” and “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934 (the “Exchange Act”), as in effect on the date of this Agreement, but shall not include the Company, any Subsidiary of or other Person controlled by the Company, any employee benefit plan of the Company or of any Subsidiary of the Company or any Person appointed as trustee by the Company or such Subsidiary pursuant to the terms of any such plan in that Person’s capacity as trustee.

(i) of which such Person or any of such Person’s Affiliates or Associates directly or indirectly has “beneficial ownership,” as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act, as in effect on the date of this Agreement;

(ii) which such Person or any of such Person’s Affiliates or Associates directly or indirectly has (A) the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (whether or not in writing), or upon the exercise of conversion rights, exchange rights, rights (other than the Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to “beneficially own,” securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase; or (B) the right (whether sole or shared) to vote or dispose of pursuant to any agreement, arrangement or understanding (whether or not in writing); provided, however, that a Person shall not be deemed the Beneficial Owner of, or to “beneficially own,” any security under this clause (B) pursuant to an agreement, arrangement or understanding to vote such security that (1) arises solely from a revocable proxy or consent given in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the Exchange Act and the rules and regulations thereunder and (2) is not also then required to be reported as beneficially owned on a Schedule 13D under the Exchange Act (or any comparable or successor report); or

(iii) which are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) with which such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (whether or not in writing) for the purpose of acquiring, holding, voting (except pursuant to a revocable proxy as described in clause (B) of subparagraph (ii) of this paragraph (c)) or disposing of any securities of the Company.

Notwithstanding anything in this definition of Beneficial Ownership to the contrary, the phrase “then outstanding,” when used with reference to a Person’s Beneficial Ownership of securities of the Company, shall mean the number of such securities then issued and outstanding together with the number of such securities not then actually issued and outstanding which such Person would be deemed to own beneficially hereunder.

(d) “Business Day” shall mean any day other than a Saturday, Sunday or a legal holiday for banking institutions in the State of Illinois.

(e) “Close of business” on any given date shall mean 5:00 P.M., Chicago time, on such date; provided, however, that if such date is not a Business Day it shall mean 5:00 P.M., Chicago time, on the next succeeding Business Day.

(f) “Common Stock” when used with reference to the Company shall mean the Common Stock, $1.00 par value, of the Company. “Common Stock” when used with reference to any Person other than the Company shall mean the capital stock with the greatest aggregate voting power or the equity securities or other equity interests having power to control or direct the management of such Person or, if such Person is a subsidiary of or controlled by another Person, the Person which ultimately controls such first-mentioned Person and which has issued and outstanding such capital stock, equity securities or equity interests.

(g) “Person” shall mean any individual, firm, corporation, partnership, trust, association, joint venture, syndicate or other entity, and shall include any successor (by merger or otherwise) of such entity.

(h) “Stock Acquisition Date” shall mean the first date of public announcement (which shall include, without limitation, a report filed pursuant to the Exchange Act) by the Company or an Acquiring Person of facts that show that an Acquiring Person has become such.

(i) “Subsidiary” of any Person shall mean any corporation or other Person of which a majority of the voting power of the voting equity securities or equity interest is owned, directly or indirectly, by such Person, or which is otherwise controlled by such Person.

(j) “Substantial Block” shall mean a number of shares of Common Stock of the Company which equals or exceeds 15% of the number of shares of Common Stock of the Company then outstanding.

Section 2. Appointment of Rights Agent. The Company hereby appoints the Rights Agent to act as agent for the Company and the holders of the Rights (who, in accordance with Section 3 hereof, shall prior to the Distribution Date also be the holders of the Common Stock) in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such Co-Rights Agents as it may deem necessary or desirable. In the event the Company appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and the Co-Rights Agents shall be as the Company determines.

Section 3. Issue of Right Certificates.

(a) Until the earlier of the close of business on (i) the tenth business day after the Stock Acquisition Date (or, the Record Date, if the tenth business day after the Stock Acquisition Date occurs before the Record Date), or (ii) the tenth business day after the commencement of, or first public announcement of, the intent of any Person (other than the Company or any of its subsidiaries or any employee benefit plan of the Company or of any subsidiary of the Company

or any Person appointed as trustee by the Company or such subsidiary pursuant to the terms of any such plan in such Person’s capacity as trustee) to commence (which intention to commence remains in effect for five business days after such announcement) a tender or exchange offer which would result in such Person becoming an Acquiring Person (including any such day which is after the date of this Agreement and prior to the issuance of the Rights, the earlier of such dates being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced by the certificates for the Common Stock of the Company registered in the names of the holders of the Common Stock (which certificates for Common Stock shall be deemed also to be Right Certificates) and not by separate Right Certificates, and (y) the right to receive Right Certificates will be transferable only in connection with the transfer of Common Stock. As soon as practicable after the Distribution Date, the Rights Agent will send, by first-class, insured, postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Distribution Date, at the address of such holder shown on the records of the Company, a certificate for Rights, in substantially the form of Exhibit A hereto (the “Rights Certificates”), evidencing one Right for each share of Common Stock so held. As of and after the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

(b) As soon as practicable after the Record Date, the Company will send a copy of a Summary of Rights to Purchase Common Stock, in substantially the form attached hereto as Exhibit B (the “Summary of Rights”), by first-class, postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Record Date, at the address of such holder shown on the records of the Company. With respect to certificates for the Common Stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for the Common Stock registered in the names of the holders of the Common Stock. Until the Distribution Date (or earlier Expiration Date), the surrender for transfer of any of the certificates for the Common Stock outstanding on the Record Date shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificate.

(c) Rights shall be issued in respect of all shares of Common Stock which become outstanding after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date. Certificates representing such shares shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement between AAR CORP. and Computershare Trust Company, N.A. dated as of July 11, 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 AAR CORP. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be redeemed, may expire or may be evidenced by separate certificates and will no longer be evidenced by this certificate. AAR CORP. will mail to the holder of this certificate a copy of the Rights Agreement without charge promptly upon receipt of a written request therefor. Under certain circumstances, Rights issued to, or held by, an Acquiring Person or Associates or

Affiliates of an Acquiring Person (as defined in the Rights Agreement) and any subsequent holder of such Rights may become null and void.

With respect to such certificates containing the foregoing legend, until the Distribution Date, the Rights associated with the Common Stock represented by such certificates shall be evidenced by such certificates alone, and the surrender for transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificate.

Section 4. Form of Right Certificates.

(a) The Right Certificates (and the forms of election to purchase shares and of assignment to be printed on the reverse thereof) shall be substantially the same as Exhibit A hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Right Certificates, whenever issued, shall be dated as of the Record Date, and on their face shall entitle the holders thereof to purchase such number of shares of Common Stock as shall be set forth therein at the price per share set forth therein (the “Purchase Price”), but the number of such shares and the Purchase Price shall be subject to adjustments as provided herein.

(b) Any Right Certificate that represents Rights beneficially owned by an Acquiring Person or any Associate or Affiliate of an Acquiring Person and any Rights Certificate issued at any time upon the transfer of any Rights to such an Acquiring Person or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate, and any Rights Certificate issued pursuant to Section 6 or Section 11 upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain the following legend:

The Rights represented by this Rights Certificate were issued to 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, dated as of July 11, 2007). This Rights Certificate and the Rights represented hereby may become void to the extent provided by, and under certain circumstances as specified in, Section 7(e) of the Rights Agreement.

The provisions of Section 7(e) of this Rights Agreement shall be operative whether or not the foregoing legend is contained on any such Rights Certificate.

Section 5. Countersignature and Registration.

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

(b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at one of its offices in Chicago, Illinois, books for registration and transfer of the Right Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Right Certificates, the number of Rights evidenced on its face by each of the Right Certificates and the date of each of the Right Certificates.

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

(a) Subject to the provisions of Section 15 hereof, at any time after the close of business on the Distribution Date, and at or prior to the close of business on the Expiration Date, any Right Certificate or Certificates 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 shares of Common Stock as the Right Certificate or Right Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Right Certificate shall make such request in writing delivered to the Rights Agent, and shall surrender the Right Certificate or Right Certificates to be transferred, split up, combined or exchanged at the principal office of the Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the person entitled thereto a Right Certificate or Right Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Right Certificates.

(b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Right Certificate if

mutilated, the Company will make and deliver a new Right Certificate of like tenor to the Rights Agent for delivery to the registered owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

(a) The registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date, upon surrender of the Right Certificate, with the form of election to purchase on the reverse side thereof duly executed, to the Rights Agent at the principal office of the Rights Agent in Chicago, Illinois, together with payment of the Purchase Price for each share of Common Stock of the Company as to which the Rights are exercised, at or prior to the close of business on the earlier of the close of business on (i) August 6, 2017 (the “Final Expiration Date”), or (ii) the date on which the Rights are redeemed pursuant to Section 24 (such earlier date being herein referred to as the “Expiration Date”).

(b) The Purchase Price for each share of Common Stock pursuant to the exercise of a Right shall initially be $140.00, shall be subject to adjustment from time to time as provided in Sections 11 and 13 and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below.

(c) Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase duly executed, accompanied by payment of the Purchase Price for the shares to be purchased, and an amount equal to any applicable transfer tax in cash, or by certified check or bank draft payable to the order of the Company, the Rights specified in the election shall be exercised, and the Rights Agent shall, subject to Section 21(j), thereupon promptly (i) (A) requisition from any transfer agent of the Common Stock of the Company (or make available, if the Rights Agent is the transfer agent) certificates for the number of shares of Common Stock to be purchased (and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests), or (B) if the Company, in its sole discretion, shall have elected to deposit the shares of Common Stock issuable upon exercise of the Rights hereunder into a depositary, requisition from the depositary agent depositary receipts representing such number of shares of Common Stock as are to be purchased (in which case certificates for the shares of Common Stock represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company will direct the depositary agent to comply with such request, (ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuance of fractional shares in accordance with Section 15, (iii) promptly after receipt of such certificates, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by such holder and (iv) when appropriate, after receipt promptly deliver such cash to or upon the order of the registered holder of such Right Certificate. The payment of the Purchase Price may be made (x) in cash or by certified bank check or bank draft payable to the order of the Company, or (y) by delivery of a certificate or certificates (with appropriate stock powers executed in blank attached thereto) evidencing a number of shares of Common Stock equal to the then Purchase Price divided by the closing price (as determined pursuant to Section 11(d) hereof) per share of Common Stock on the Trading Day immediately preceding the date of such exercise. In the

event that the Company is obligated to issue other securities (including shares of Common Stock) of the Company, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution by the Rights Agent, if and when appropriate. In addition, in the case of an exercise of the Rights by a holder pursuant to Section 11(a)(ii), the Rights Agent shall return such Rights Certificate to the registered holder thereof after imprinting, stamping or otherwise indicating thereon that the rights represented by such Rights Certificate no longer include the rights provided by Section 11(a)(ii) of the Rights Agreement and if less than all the Rights represented by such Rights Certificate were so exercised, the Rights Agent shall indicate on the Rights Certificate the number of Rights represented thereby which continue to include the rights provided by Section 11(a)(ii).

(d) In case the registered holder of any Right Certificate shall exercise (except pursuant to Section 11(a)(ii)) less than all the Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent to the registered holder of such Right Certificate or to his duly authorized assigns, subject to the provisions of Section 15.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of an event described in Section 11(a)(ii), any Rights beneficially owned (including beneficial ownership that can be deemed to exist because of the transfer of voting rights pursuant to a voting trust or similar arrangement) by an Acquiring Person or an Associate or Affiliate of an Acquiring Person shall be void and any holder of such Rights shall thereafter have no right to exercise such Rights under any provision of this Agreement. No Rights Certificate shall be issued pursuant to Section 3 that represents Rights beneficially owned by an Acquiring Person whose Rights are void pursuant to the preceding sentence or any Associate or Affiliate thereof; no Rights Certificate shall be issued at any time upon the transfer of any Rights to an Acquiring Person whose Rights are void pursuant to the preceding sentence or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate; and any Rights Certificate delivered to the Rights Agent for transfer to an Acquiring Person (or Associate or Affiliate thereof) whose Rights are void pursuant to the preceding sentence shall be cancelled.

(f) Notwithstanding anything in this Agreement to the contrary, the Rights shall not be effectively exercised and neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7, unless such registered holder shall have (i) completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Right Certificate surrendered for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request.

Section 8. Cancellation and Destruction of Right Certificates. All Right Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by it,

and no Right Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Rights Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Right Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. Reservation and Availability of Shares of Common Stock.

(a) The Company covenants and agrees that after the occurrence of an event described in Section 11 it will cause to be reserved and kept available, and not reserved for other purposes, out of its authorized and unissued shares of Common Stock or its authorized and issued shares of Common Stock held in its treasury, the number of shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Rights.

(b) So long as the Common Stock issuable upon the exercise of Rights may be listed on any national securities exchange, the Company shall use its best efforts to cause, from and after the Distribution Date, all shares reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise.

(c) The Company covenants and agrees that it will take all such action as may be necessary to insure that all shares of Common Stock delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable shares.

(d) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges which may be payable in respect of the issuance or delivery of the Right Certificates or of any shares of Common Stock upon the exercise of Rights. The Company shall not, however, be required to pay any transfer tax which may be payable in respect of any transfer involved in the transfer or delivery of Right Certificates or the issuance or delivery of certificates for Common Stock 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 for shares of Common Stock upon the exercise of any Rights until any such tax shall have been paid (any such tax being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax is due.

(e) The Company shall use its best efforts to (i) file, as soon as practicable following the Distribution Date, a registration statement under the Securities Act of 1933 (the “Act”), with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act and the rules and regulations thereunder) 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 securities or “blue sky” laws of the various states in connection with the exercisability of the Rights.

Section 10. Common Stock Record Date. Each person in whose name any certificate for shares of Common Stock is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Stock represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and any applicable transfer taxes) was made in accordance with Section 7; provided, however, that if the date of such surrender and payment is a date upon which the Common Stock transfer books of the Company are closed, such person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding business day on which the Common Stock transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Right Certificate shall not be entitled to any rights of a stockholder of the Company with respect to shares for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

Section 11. Adjustment of Purchase Price, Number of Shares or Number of Rights. The Purchase Price, the number of shares covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

(a) (i) In the event the Company shall at any time after the date of this Agreement (A) declare a dividend on the Common Stock payable in shares of Common Stock, (B) subdivide the outstanding shares of Common Stock, (C) combine the outstanding shares of Common Stock into a smaller number of shares or (D) issue any shares of its capital stock in a reclassification or recapitalization of the Common Stock (including any such reclassification or recapitalization in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided this Section 11(a) and in Section 7(e), the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination, reclassification or recapitalization, and the number and kind of shares of capital stock issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive the aggregate number and kind of shares of capital stock, other securities and/or property which, if such Right had been exercised immediately prior to such date and at a time when the Common Stock transfer books of the Company were open, such holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination, reclassification or recapitalization; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon the exercise of one Right. If an event occurs which would require an adjustment under both Section 11(a)(i) and Section 11(a)(ii), the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii).

(ii) In the event that at any time after the date hereof, any Person, alone or together with its Affiliates and Associates, shall become an Acquiring Person then proper provision shall be made so that each holder of a Right, except as provided in Section 7(e) hereof, shall have a right to receive, upon exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, such number of shares of Common Stock of the Company as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of shares of Common Stock for which a Right is then exercisable and dividing that product by (y) 50% of the current market price for one share of Common Stock (determined pursuant to Section 11(d)) on the date of the occurrence of the event set forth above in this subparagraph (ii) (such number of shares being referred to as the “number of Adjustment Shares”); provided, however, that if the transaction that would otherwise give rise to the foregoing adjustment is also subject to the provisions of Section 13 hereof, then only the provisions of Section 13 hereof shall apply and no adjustment shall be made pursuant to this Section 11(a)(ii).

(iii) In the event that there shall not be sufficient treasury shares or authorized but unissued shares of Common Stock to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) or, if any regulatory approvals for the issuance of such Common Stock has not been obtained by the Company, and the Rights become so exercisable, notwithstanding any other provision of this Agreement, to the extent necessary and permitted by applicable law and any agreements in effect on the date hereof to which it is a party, the Company shall, with respect to each Right, make adequate provision to substitute upon exercise of such Right to the extent necessary and on a pro rata or such other basis as the Company deems appropriate, (1) cash, (2) a reduction in the Purchase Price, (3) other equity securities of the Company (including without limitation shares or units of shares of preferred stock or other securities), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate value equal to the “current per share market price” (as determined pursuant to Section 11(d) hereof) of the Common Stock for which such Right is otherwise exercisable, where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors of the Company.

(b) In case a record date is fixed by the Company or otherwise established for the issuance of rights, options or warrants to all holders of Common Stock entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Stock (or securities convertible into Common Stock) at a price per share of Common Stock (or having a conversion price per share of Common Stock, if a security convertible into Common Stock) less than the current market price (as defined in Section 11(d)) per share of Common Stock on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding on such record date plus the number of shares of Common Stock which the aggregate offering price of the total number of shares of Common Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price and of which the denominator shall be the number of

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

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

(d) For the purpose of any computation hereunder, the “current market price” per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of Common Stock for the 30 consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, that in the event that the current market price per share of Common Stock is determined during a period following the announcement by the issuer of the Common Stock of (i) a dividend or distribution on the Common Stock payable in shares of Common Stock or securities convertible into shares of Common Stock or (ii) any subdivision, combination or reclassification of the Common Stock, and prior to the expiration of 30 Trading Days after the ex-dividend date for such dividend or

distribution, or the record date for such subdivision, combination or reclassification, as the case may be, then, and in each such case, the “current market price” shall be appropriately adjusted to reflect the current market price per common share equivalent. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the shares of Common Stock are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotations System (“NASDAQ”) or such other system then in use, or, if on any such date the shares of Common Stock 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 Stock selected by the Board of Directors of the Company, except that, if on any such date no market maker is making a market in the Common Stock, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading is open for the transaction of business or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Stock is not publicly held or not so listed or traded, “current market price” per share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent.

(e) No adjustment in the Purchase Price shall 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 shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest ten-thousandth of a share as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which mandates such adjustment or (ii) the Expiration Date.

(f) If as a result of an adjustment made pursuant to Section 11(a) or Section 13(a), the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the shares contained in Section 11(a) through (c), inclusive, and the provisions of Sections 7, 9, 10, 13 and 15 with respect to the shares of Common Stock shall apply on like terms to any such other shares.

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of shares of Common Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Section 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of shares (calculated to the nearest ten-thousandth) obtained by (i) multiplying (x) the number of shares covered by a Right immediately prior to this adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in substitution for any adjustment in the number of shares of Common Stock purchasable upon the exercise of a Right. Each of the Rights outstanding after such adjustment of the number of Rights shall be exercisable for the number of shares of Common Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. 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, the record date shall be at least 10 days later than the date of the public announcement. If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Right Certificates on such record date Right Certificates evidencing, subject to Section 15, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Right Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

(j) Irrespective of any adjustment or change in the Purchase Price or the number of shares of Common Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase Price per share and the number of shares which were expressed in the initial Right Certificates issued hereunder.

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

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

(m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that it in its sole discretion shall determine to be advisable in order that any consolidation or subdivision of the Common Stock, issuance wholly for cash of any shares of Common Stock at less than the current market price, issuance wholly for cash of shares of Common Stock or securities which by their terms are convertible into or exchangeable for shares of Common Stock, stock dividends or issuance of rights, options or warrants referred to hereinabove in this Section 11, hereafter made by the Company to holders of its Common Stock shall not be taxable to such stockholders.

(n) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time after the date of this Agreement (i) declare a dividend on the outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, (iii) combine the outstanding Common Stock into a smaller number of shares or (iv) issue any shares of its capital stock in a reclassification of the outstanding Common Stock, the number of Rights associated with each share of Common Stock then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock immediately prior to such event (or, in the event that any adjustment is made in connection with such event by reason of Section 11(i), after such adjustment) by a fraction the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately after the occurrence of the event.

(o) Notwithstanding any other provision of this Agreement, no adjustment to the Purchase Price, the number of shares of Common Stock (or fractions of a share) for which a Right is exercisable or the number of Rights outstanding (except as permitted by Section 23

hereof) or any similar adjustment shall be made or be effective if such adjustment would have the effect of reducing or limiting the benefits the holders of the Rights would have had absent such adjustment, including, without limitation, the benefits under Section 11(a)(ii) and Section 13, unless the terms of this Agreement are amended so as to preserve such benefits.

(p) The Company covenants and agrees that, following the Distribution Date, except as permitted by Section 24 or Section 26 hereof, it will not, directly or indirectly, take any action the purpose or effect of which is to eliminate or otherwise diminish the benefits intended to be afforded by the Rights.

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

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

(a) In the event that, on or after the Stock Acquisition Date, directly or indirectly, (i) the Company shall consolidate with, or merge with and into, any other Person, and the Company shall not be the continuing or surviving corporation, (ii) any Person shall consolidate with the Company, or merge with and into the Company, and the Company shall be the continuing or surviving corporation and, in connection therewith, all or part of the Common Stock of the Company shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (iii) the Company shall sell or otherwise transfer (or one or more of its subsidiaries shall sell or otherwise transfer), in one or more transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its subsidiaries (taken as a whole) to any other Person or Persons, then, and in each such case, proper provision shall be made so that (A) each holder of a Right, subject to Section 7(e), shall thereafter have the right to receive, upon the exercise thereof at the then-current Purchase Price in accordance with the terms of this Agreement, such number of validly authorized and issued, fully paid, non-assessable and freely tradeable shares of Common Stock of the Principal Party (as hereinafter defined), free and clear of any liens, encumbrances and adverse claims and not subject to any rights of call, purchase or first refusal, as shall be equal to the result obtained by (x) multiplying the then current Purchase Price by the number of shares of Common Stock for which a Right is then exercisable (without taking into account any adjustment previously made pursuant to Section 11(a)(ii) hereof) and dividing that product by (y) 50% of the current market price (determined pursuant to Section 11(d)) per share of the Common Stock of the Principal Party on the date of consummation of such consolidation, merger, sale or transfer; (B) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such consolidation, merger, sale or transfer, all the obligations and duties of the Company pursuant to this Agreement; (C) the term “Company” shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence of an event set forth

in Section 13(a) hereof; and (D) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of shares of its Common Stock in accordance with Section 9) in connection with such consummation as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to the shares of its Common Stock or cash, property or other securities thereafter deliverable upon the exercise of the Rights.

(b) “Principal Party” shall mean (i) in the case of any transaction described in (i) or (ii) of the first sentence of Section 13(a), the Person that is the issuer of any securities into which shares of Common Stock of the Company are converted in such merger or consolidation, and if no securities are so issued, the Person that is the other party to such merger or consolidation; and (ii) in the case of any transaction described in (iii) of the first sentence in Section 13(a), the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions; provided, however, that in any such case, (1) if the shares of Common Stock of such Person are not at such time and have not been continuously over the preceding twelve month period registered under Section 12 of the Exchange Act (“Registered Common Shares”) or such Person is not a corporation, and such Person is directly or indirectly controlled by another Person which has Registered Common Shares outstanding, “Principal Party” shall refer to such other Person; (2) if the shares of Common Stock of such Person are not Registered Common Shares or such Person is not a corporation, and such Person is directly or indirectly controlled by another Person which does not have Registered Common Shares outstanding, “Principal Party” shall refer to the controlling Person of such first-mentioned Person; (3) if the shares of Common Stock of such Person are not Registered Common Shares or such Person is not a corporation, and such Person is directly or indirectly controlled by more than one Person, and one or more of such controlling Persons have Registered Common Shares outstanding, “Principal Party” shall refer to whichever of such controlling Persons is the issuer of the Registered Common Shares having the greatest aggregate market value; and (4) if the shares of Common Stock of such Person are not Registered Common Shares or such Person is not a corporation, and such Person is directly or indirectly controlled by more than one Person, and none of such controlling Persons have Registered Common Shares outstanding, “Principal Party” shall refer to whichever controlling Person is the corporation having the greatest stockholders equity or, if no such controlling Person is a corporation, shall refer to whichever controlling Person has the greatest net assets.

(c) The Company shall not consummate any such consolidation, merger, sale or transfer unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a legally valid, binding and enforceable supplemental agreement in compliance with the provisions set forth in Section 13(a) and (b), and if applicable Section 13(d), and further providing that, as soon as practicable after the date of any consolidation, merger or sale of assets mentioned in this Section 13, such issuer will (i) prepare and file a registration statement under the Act, with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such filing and (B) remain effective (with a prospectus at all times meeting the requirements of the Act) until the Expiration Date; and (ii) use its best efforts to qualify or register the Rights and the securities purchasable upon exercise of the Rights under the blue sky laws of such jurisdictions as may be necessary or

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

(d) Notwithstanding anything in Section 13(b) and (c) to the contrary, if the Principal Party as determined pursuant to paragraph (b) above is not a corporation or does not have shares of Common Stock, proper provision shall be made so that such Principal Party shall create or otherwise make available for purposes of the exercise of the Rights in accordance with the terms of this Agreement, cash or a type or types of securities having a fair market value (as determined by a nationally recognized investment banking firm selected by the Board of Directors of the Company) equal to at least the value of the shares of Common Stock which each holder of a Right would have been entitled to receive if such Principal Party had been a corporation or had shares of Common Stock.

(e) The Company covenants and agrees that, following the Distribution Date, it shall not consummate any of the transactions described in clauses (i), (ii) and (iii) of the first sentence of Section 13(a) if at the time of or after such consummation there would be any charter or by-law provisions or any rights, warrants or other instruments or securities outstanding or agreements in effect or any other action taken which would diminish or eliminate the benefits intended to be afforded by the Rights, unless prior thereto the Principal Party shall have amended or repealed such charter or by-law provisions, instruments or securities, agreements or actions or otherwise protected the holders of the Rights from such diminution or elimination of benefits, and the Company and the Principal Party shall have executed and delivered to the Rights Agent a legally valid, binding and enforceable supplemental agreement providing for such amendment, repeal or other protection.

(f) The provisions of this Section 13 shall similarly apply to successive mergers, consolidations, sales or other transfers. Notwithstanding the occurrence of any transaction set forth in Section 11(a)(ii), in the event that any transaction set forth in Section 13 subsequently occurs, the Rights which have not theretofore been exercised shall thereafter become exercisable in the manner described in this Section 13.

Section 14. Additional Covenants.

(a) After the Stock Acquisition Date, the Company covenants and agrees that it shall not (i) consolidate with, (ii) merge with or into, or (iii) sell or transfer to, in one or more transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its subsidiaries taken as a whole, any other Person if at the time of or after such consolidation, merger or sale there are any charter or by-law provisions or any rights, warrants or other instruments outstanding or any other action taken which would diminish or otherwise eliminate the benefits intended to be afforded by the Rights. The Company shall not consummate any such consolidation, merger or sale unless prior thereto the Company and such other Person shall have executed and delivered to the Rights Agent a supplemental agreement evidencing compliance with this subsection.

Section 15. Fractional Rights and Fractional Shares.

(a) The Company shall not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For the purposes of this Section 15(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company, except that, if on any such date no such market maker is making a market in the Rights, the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Company shall be used.

(b) The Company shall not be required to issue fractions of shares upon exercise of the Rights or to distribute certificates which evidence fractional shares. In lieu of fractional shares, the Company may pay to the registered holders of Right Certificates at the time such Right Certificates are exercised as herein provided an amount in cash equal to the same fraction of the current market value of a share of Common Stock. For purposes of this Section 15(b), the current market value of a share of Common Stock shall be the closing price of a share of Common Stock (as determined pursuant to the second sentence of Section 11(d)) for the Trading Day immediately prior to the date of such exercise.

(c) Each holder of a Right or Rights by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right or Rights.

Section 16. Rights of Action. All rights of action in respect of 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 Stock); and any registered holder of any Right Certificate (or, prior to the Distribution Date, of the Common Stock), without the consent of the Rights Agent or of the holder of any other Right Certificate (or, prior to the Distribution Date, of the Common Stock), may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Right Certificate in the manner

provided in such Right Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of, the obligations of any Person subject to this Agreement. Holders of Rights shall be entitled to recover the reasonable costs and expenses, including attorneys’ fees, incurred by them in any action to enforce the provisions of this Agreement.

Section 17. Agreement of Right Holders. Every holder of a Right by accepting the same consents and agrees with the Company and the Rights Agent and with every other holder of a Right that:

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

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

(c) the Company and the Rights Agent may deem and treat the person in whose name each Right Certificate (or, prior to the Distribution Date, the associated Common Stock certificate) 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 Stock certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary.

Section 18. Right Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Right Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of Common Stock or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Right Certificate be construed to confer upon the holder of any Right Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 25), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof.

Section 19. Concerning the Rights Agent.

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The

Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability in the premises.

(b) The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any Right Certificate or certificate for Common Stock or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper person or persons.

Section 20. Merger or Consolidation or Change of Name of Rights Agent.

(a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the corporate trust business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 22. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

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

Section 21. Terms and Conditions to Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Right Certificates, by their acceptance thereof, shall be bound:

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full authorization to the Rights Agent for any action taken or omitted by it in good faith and in accordance with such opinion.

(b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or omitting any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chairman of the Board, the Vice Chairman of the Board, the President or any Executive or Senior Vice President and by the Treasurer or any Assistant Treasurer or the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action taken or omitted by it in good faith under the provisions of this Agreement in reliance upon such certificate.

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

(e) The Rights Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Right Certificate; nor shall it be responsible for any adjustment required under the provisions of Sections 11 or 13 or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after actual notice of any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Right Certificate or as to whether any shares of Common Stock will, when issued, be validly authorized and issued, fully paid and nonassessable.

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

(g) The Rights Agent is hereby authorized and directed to accept determinations, interpretations and instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the Vice Chairman of the Board, the President or any Executive or Senior Vice President or the Secretary or any Assistant Secretary or the Treasurer or any

Assistant Treasurer of the Company, and to apply to such officers for advice or instructions in connection with its duties, and it shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with determinations, interpretations and instructions of any such officer.

(h) The Rights Agent and any shareholder, 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 it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity.

(i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

(j) If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase, as the case may be, has either not been completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise of transfer without first consulting with the Company.

Section 22. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Right Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Right Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting or shall repeatedly fail or refuse to act, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity or repeated failure or refusal to act by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall, with such notice, submit his Right Certificate for inspection by the Company), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation or trust company organized and doing business under the laws of the United States, in good standing, which is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by federal or state authority and which has individually or combined with an affiliate at the time of its appointment as Rights Agent a combined capital and surplus of at least $100 million dollars. After appointment, the

successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock, 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 22, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

Section 23. Issuance of New Right Certificates. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price per share and the number or kind or class of shares of stock or other securities or property purchasable under the Right Certificates made in accordance with the provisions of this Agreement.

Section 24. Redemption.

(a) The Board of Directors of the Company may, at its option, at any time prior to the earlier of (i) the close of business on the tenth business day after the Stock Acquisition Date or (ii) the Final Expiration Date, redeem all but not less than all the then outstanding Rights at a redemption price of $.01 per Right, as such amount may be appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the “Redemption Price”).

(b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights, and without any further action and without any notice, the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price. As soon as practicable after the action of the Board of Directors ordering the redemption of the Rights, the Company shall 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 Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Such notice of redemption shall state the method by which the payment of the Redemption Price will be made. Neither the Company nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section 24, and other than in connection with the repurchase of Common Stock prior to the Distribution Date.

(c) The Company may, at its option, discharge all of its obligations with respect to the Rights by (i) issuing a press release announcing the manner of redemption of the Rights and (ii) mailing payment of the Redemption Price to the registered holders of the Rights at their last addresses as they appear on the registry books of the Rights Agent or, prior to the Distribution

Date, on the registry books of the Transfer Agent of the Common Stock, and upon such action, all outstanding Rights Certificates shall be null and void without any further action by the Company.

Section 25. Exchange.

(a) Subject to Section 15(b), the Board of Directors of the Company may, at its option, at any time after the time that any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) and Section 11(a)(ii) hereof) for shares of Common Stock of the Company at an exchange ratio of one share of Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such exchange ratio being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than the Company, any subsidiary of the Company, any employee benefit plan of the Company or any such subsidiary, any entity holding shares of Common Stock for or pursuant to the terms of any such plan or any trustee, administrator or fiduciary of such a plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the shares of Common Stock then outstanding.

(b) Immediately upon the action of the Board of Directors of the Company ordering the exchange of any Rights pursuant to subsection (a) of this Section 25 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive that number of shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice of any such exchange; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the shares of Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 7(e) and Section 11(a)(ii) hereof) held by each holder of Rights.

(c) In the event that there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 25, the Company shall take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exchange of the Rights; and, consistent with the provisions of Section 9(e) and Section 11(a)(iii) hereof, in the event the Company is unable to cause shares of Common Stock to be delivered in exchange for Rights for any reason within 90 days after the announcement of the decision to exchange Rights pursuant to Section (a) of this Section 25, the Company shall substitute for each share of Common Stock otherwise issuable upon the exchange of Rights, cash, other assets or other securities of the

Company (or any combination of the foregoing) having an aggregate value equal to the “current per share market price” (as determined pursuant to Section 11(d)(ii) hereof), as determined by the Board of Directors of the Company.

Section 26. Notice of Certain Events. In case the Company shall propose (a) to pay any dividend payable in stock of any class to the holders of its Common Stock or to make any other distribution to the holders of its Common Stock (other than a regular periodic cash dividend out of earnings or retained earnings or other than a special cash dividend declared at a time when there is no Acquiring Person out of earnings or retained earnings, or (b) to offer to the holders of its Common Stock rights or warrants to subscribe for or to purchase any additional shares of Common Stock or shares of stock of any class or any other securities, rights or options, or (c) to effect any reclassification of its Common Stock (other than a reclassification involving only the subdivision of outstanding shares of Common Stock), or (d) to effect any consolidation or merger into or with, or to effect any sale or other transfer (or to permit one or more of its subsidiaries to effect any sale or other transfer), in one or more transactions, of more than 50% of the assets or earning power of the Company and its subsidiaries (taken as a whole) to, any other Person or Persons, or (e) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Right, in accordance with Section 26, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (a) or (b) above at least twenty days prior to the record date for determining holders of the Common Stock for purposes of such action, and in the case of any such other action, at least twenty days prior to the date of the taking of such proposed action or the date of participation therein by the holders of Common Stock, whichever shall be the earlier.

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

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

Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section 28, the Rights Agent shall execute such supplement or amendment unless the Rights Agent shall have determined in good faith that such supplement or amendment would adversely affect its interest under this Agreement.

As provided in the Rights Agreement, the Purchase Price and the number of shares of Common Stock or other securities which may be purchased upon the exercise of the Rights evidenced by this Rights Certificate are subject to modification and adjustment upon the happening of certain events.

This Rights Certificate is subject to all of the terms, provisions and conditions of the Rights Agreement, which terms, provisions and conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Company and the holders of the Rights Certificates.

This Rights Certificate, with or without other Rights Certificates, upon surrender at the office of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing Rights entitling the holder to purchase a like aggregate number of shares of Common Stock as the Rights evidenced by the Rights Certificate or Rights Certificates surrendered shall have entitled such holder to purchase.

AAR CORP.
SUMMARY OF RIGHTS TO PURCHASE
COMMON STOCK

On July 10, 2007, the Board of Directors of AAR CORP. (the “Company”) declared a dividend distribution of one Right for each outstanding share of Common Stock, $1.00 par value (the “Common Stock”), of the Company to the stockholders of record on August 6, 2007 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company one share of Common Stock at a price of $140.00 per share (the “Purchase Price”), subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement (the “Rights Agreement”) between the Company and Computershare Trust Company, N.A., as Rights Agent (the “Rights Agent”). The Rights replace the common stock purchase rights which were distributed to the Company’s stockholders in 1997.

Until the earlier to occur of (i) the tenth business day after a public announcement that a person or group of affiliated or associated persons acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock of the Company (such person or group being called an “Acquiring Person” and such date of first public announcement being called the “Stock Acquisition Date”), or (ii) the tenth business day after the commencement or announcement of an intention to make a tender offer or exchange offer which would result in any person or group of affiliated or associated persons becoming an Acquiring Person (the earlier of such dates being called the “Distribution Date”), the Rights will be evidenced, with respect to any of the Company’s Common Stock certificates outstanding as of the Record Date, by such Common Stock certificate with a copy of this Summary of Rights attached thereto. The Rights Agreement provides that, until the Distribution Date, the Rights will be transferred with and only with the Company’s Common Stock. Until the Distribution Date (or earlier redemption or expiration of the Rights), new Common Stock certificates issued after the Record Date upon transfer or new issuance of the Company’s Common Stock will contain a notation incorporating the Rights Agreement by reference. Until the Distribution Date (or earlier redemption or expiration of the Rights), the surrender for transfer of any of the Company’s Common Stock certificates outstanding as of the Record Date will also constitute the transfer of the Rights associated with the Common Stock represented by such certificate. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Rights Certificates”) will be mailed to holders of record of the Company’s Common Stock as of the close of business on the Distribution Date and, thereafter, such separate Rights Certificates alone will evidence the Rights.

The Rights are not exercisable until the Distribution Date. The Rights will expire on August 6, 2017, unless earlier redeemed by the Company as described below.

The Purchase Price payable, and the number of shares of Common Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of the Common Stock, (ii) upon the grant to holders of Common Stock of certain

rights, options or warrants to subscribe for shares of Common Stock or convertible securities at less than the current market price of the Common Stock or (iii) upon the distribution to holders of Common Stock of evidences of indebtedness or assets (excluding (a) a regular periodic cash dividend or (b) a dividend payable in Common Stock) or of subscription rights, options or warrants (other than those referred to above).

In the event that a person becomes the beneficial owner of 15% or more of the outstanding shares of Common Stock (i.e., becomes an Acquiring Person), each holder of a Right, other than Rights beneficially owned by the Acquiring Person (which will be void), will have the right to receive upon exercise thereof, that number of shares of Common Stock having a market value of two times the exercise price of the Right (such right being called the “Flip-In” right).

In the event that, on or after the Stock Acquisition Date, the Company were acquired in a merger or other business combination, or 50% or more of its assets or earning power were sold, proper provision shall be made so that each holder of a Right shall thereafter have the right to receive, upon the exercise thereof at the then current exercise price of the Right, that number of shares of common stock of the acquiring company which at the time of such transaction would have a market value of two times the exercise price of the Right. In the event that the Company were the surviving corporation in a merger involving the Acquiring Person and the Common Stock were not changed or exchanged, proper provision shall be made so that each holder of a Right, other than Rights beneficially owned by the Acquiring Person (which will be void), will thereafter have the right to receive upon exercise that number of shares of the Common Stock having a market value of two times the exercise price of the Right (such right being called the “Flip-Over” right). The holder of a right will no longer have a Flip-Over right if, and to the extent that, he has exercised his Flip-In right.

With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price. No fractional shares will be issued and, in lieu thereof, a cash payment will be made based on the market price of the Common Stock on the last trading date prior to the date of exercise.

At any time prior to the tenth day after the time that there is an Acquiring Person, the Company may, at its option, redeem the Rights in whole but not in part, at a price of $0.01 per Right (the “Redemption Price”). Immediately upon the authorization of the redemption of the Rights by the Board of Directors of the Company, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.

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

The Board of Directors of the Company may amend the Rights Agreement from time to time, provided that any such changes do not adversely affect the interest of the holders of the Rights, and provided further that the Rights Agreement may not be supplemented or amended in any way after an Acquiring Person has become such.
