RECITALS

WHEREAS, on March 24, 2008, the Board of Directors of the Company adopted this Agreement, and has authorized and declared a dividend of one preferred share purchase right (a “ Right ”) for each Common Share (as defined in Section 1.6) of the Company outstanding at the close of business on April 15, 2008 (the “ Record Date ”) and has authorized and directed the issuance of one Right (subject to adjustment as provided herein) with respect to each Common Share that shall become outstanding between the Record Date and the earliest of the Distribution Date and the Expiration Date (as such terms are defined in Sections 3.1 and 7.1), each Right initially representing the right to purchase one one-thousandth (subject to adjustment) of a share of Series A Participating Preferred Stock (the “ Preferred Shares ”) of the Company having the rights, powers and preferences set forth in the form of Certificate of Determination attached hereto as Exhibit A , upon the terms and subject to the conditions hereinafter set forth; provided , however , that Rights may be issued with respect to Common Shares that shall become outstanding after the Distribution Date and prior to the Expiration Date in accordance with Section 22.

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:

1.1. “ Acquiring Person ” shall mean any Person (as such term is hereinafter defined) who or which, together with all Affiliates and Associates (as such terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as such term is hereinafter defined) of 15% or more of the Common Shares of the Company then outstanding but shall not include (i) an Exempt Person (as such term is hereinafter defined) or (ii) if, as of the date hereof, any Person is the Beneficial Owner of 15% or more of the Common Shares outstanding (an “ Existing Holder ”), such Existing Holder shall not be or become an “Acquiring Person” unless and until such time as such Existing Holder shall become the Beneficial Owner of one or more additional Common Shares of the Company (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Shares in Common Shares or pursuant to a split or subdivision of the outstanding Common Shares), unless, upon becoming the Beneficial Owner of such additional Common Shares, such Existing Holder is not then the Beneficial Owner of 15% or more of the Common Shares then outstanding. Notwithstanding the foregoing, no Person shall become an “Acquiring Person” as the result of an acquisition of Common Shares by the Company which, by reducing the number of shares outstanding, increases the proportionate number of shares Beneficially Owned by such Person to 15% or more of the Common Shares of the Company then outstanding; provided , however , that if a Person shall become the Beneficial Owner of 15% or more of the Common Shares of the Company then

outstanding solely by reason of share purchases by the Company and shall, after such share purchases by the Company, become the Beneficial Owner of one or more additional Common Shares of the Company (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Shares in Common Shares or pursuant to a split or subdivision of the outstanding Common Shares), then such Person shall be deemed to be an “ Acquiring Person ” unless upon becoming the Beneficial Owner of such additional Common Shares such Person does not Beneficially Own 15% or more of the Common Shares then outstanding. Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this Section 1.1, has become such inadvertently (including, without limitation, because (A) such Person was unaware that it Beneficially Owned a percentage of the Common Shares that would otherwise cause such Person to be an “ Acquiring Person ” or (B) such Person was aware of the extent of its Beneficial Ownership of Common Stock but had no actual knowledge of the consequences of such Beneficial Ownership under this Agreement), and without any intention of changing or influencing control of the Company, and such Person divests as promptly as practicable a sufficient number of Common Shares so that such Person would no longer be an Acquiring Person, as defined pursuant to the foregoing provisions of this Section 1.1 (or, in the case solely of Derivative Common Shares (as such term is hereinafter defined), such Person terminates the subject derivative transaction or transactions or disposes of the subject derivative security or securities, or establishes to the satisfaction of the Board of Directors that such Derivative Common Shares are not held with any intention of changing or influencing control of the Company), then such Person shall not be deemed to be or have become an “ Acquiring Person ” at any time for any purposes of this Agreement. For all purposes of this Agreement, any calculation of the number of Common Shares outstanding at any particular time, for purposes of determining the particular percentage of such outstanding Common Shares of which any Person is the Beneficial Owner, shall include Common Shares deemed to be Beneficially Owned by the Person in accordance with Section 1.3 , but shall not include any other unissued Common Shares which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise.

1.2. “ Affiliate ” and “ Associate ” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations, under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), as in effect on the date of this Agreement.

1.3. A Person shall be deemed the “ Beneficial Owner ” of and shall be deemed to “ Beneficially Own ” and have “ Beneficial Ownership” of any securities:

(i) which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or indirectly (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, compliance with regulatory requirements, fulfillment of a condition or otherwise) pursuant to any agreement, arrangement or understanding, whether or not in writing (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities),

2

or upon the exercise of conversion rights, exchange rights, rights, warrants or options, or otherwise; provided , however , that a Person shall not be deemed the Beneficial Owner of, or to Beneficially Own, (w) securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange, (x) securities which such Person has a right to acquire upon the exercise of Rights at any time prior to the time that any Person becomes an Acquiring Person, (y) securities issuable upon the exercise of Rights from and after the time that any Person becomes an Acquiring Person if such Rights were acquired by such Person or any of such Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3.1 or Section 22 (“ Original Rights ”) or pursuant to Section 11.9 or Section 11.15 with respect to an adjustment to Original Rights or (z) securities which such Person or any of such Person’s Affiliates or Associates may acquire, does or do acquire or may be deemed to acquire or may be deemed to have the right to acquire, pursuant to any merger or other acquisition agreement between the Company and such Person (or one or more of such Person’s Affiliates or Associates) if prior to such Person becoming an Acquiring Person the Board of Directors of the Company has approved such agreement and determined that such Person shall not be or be deemed to be the Beneficial Owner of such securities within the meaning of this Section 1.3; or (B) through any written or oral agreement, or arrangement, relationship, understanding or otherwise has or shares the power to vote, or direct the voting of such securities; provided , however , that a Person shall not be deemed the Beneficial Owner of, or to Beneficially Own, any security under this clause (B) if the agreement, arrangement or understanding to vote such security (1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations of the Exchange Act and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report);

(iii) which are Beneficially Owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) and with respect to which such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), whether or not in writing, for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in the proviso to Section 1.3(ii)(B)) or disposing of any securities of the Company with any other Person that Beneficially Owns, or whose Affiliates or Associates Beneficially Own, directly or indirectly, such securities; or

(iv) that are the subject of a derivative transaction entered into by such Person, or derivative security acquired by such Person, which gives such Person the economic equivalent of ownership of an amount of such securities due to the fact that the value of the derivative is explicitly determined by reference to the price or value of such securities, without regard to whether (a) such derivative conveys any voting rights in such securities to such Person, (b) the derivative is required to be, or capable of being, settled through delivery of such securities, or (c) such Person may have entered into other transactions that hedge the economic effect of such derivative. In determining the number of Common Shares deemed Beneficially Owned by virtue of the operation of this Section 1.3(iv), the subject Person shall be deemed to Beneficially Own (without duplication) the number of Common Shares that are synthetically owned pursuant to such derivative transactions or such derivative securities. Such Common Shares that are deemed so Beneficially Owned pursuant to the operation of this Section 1.3(iv) shall be referred to herein as “ Derivative Common Shares. ”

3

No Person who is an officer, director or employee of an Exempt Person shall be deemed, solely by reason of such Person’s status or authority as such, to be the “Beneficial Owner” of, to have “Beneficial Ownership” of or to “Beneficially Own” any securities that are “Beneficially Owned” (as defined in this Section 1.3), including, without limitation, in a fiduciary capacity, by an Exempt Person or by any other such officer, director or employee of an Exempt Person.

1.5. “ close of business ” on any given date shall mean 5:00 p.m., California time, on such date; provided , however , that if such date is not a Business Day it shall mean 5:00 p.m., California time, on the next succeeding Business Day.

1.6. “ Common Shares ” when used with reference to the Company shall mean the shares of common stock, no par value per share, of the Company. “ Common Shares ” when used with reference to any Person other than the Company shall mean the capital stock with the greatest voting power, or the equity securities or other equity interest having power to control or direct the management, of such other Person or, if such Person is a Subsidiary (as such term is hereinafter defined) of another Person, the Person or Persons which ultimately control such first-mentioned Person, and which has issued and outstanding such capital stock, equity securities or equity interest.

1.7. “ Exempt Person ” shall mean (i) the Company and any Subsidiary of the Company, in each case including, without limitation, the officers and board of directors thereof acting in their fiduciary capacity, or any employee benefit plan of the Company or of any Subsidiary of the Company or any entity or trustee holding shares of capital stock of the Company for or pursuant to the terms of any such plan, or for the purpose of funding other employee benefits for employees of the Company or any Subsidiary of the Company, (ii) Raymond D. Zinn and his Affiliates and Associates, (iii) Warren S.

1.10. “ Subsidiary ” of any Person shall mean any partnership, joint venture, limited liability company, firm, unincorporated association, trust, corporation or other entity of which a majority of the voting power of the voting equity securities or equity interests is owned, of record or beneficially, directly or indirectly, by such Person.

The Company hereby appoints the Rights Agent to act as rights agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-Rights Agents as it may deem necessary or desirable. In the event the Company appoints one or more co-Rights Agents, the respective duties of the Rights Agent and any co-Rights Agent shall be as the Company shall determine. Contemporaneously with such appointment, if any, the Company shall notify the Rights Agent thereof. The Rights Agent shall have no duty to supervise, and in no event shall be liable for, the acts or omissions of any such co-Rights Agent.

Section 3. Issuance of Right Certificates .

3.1.  Rights Evidenced by Share Certificates . Until the close of business on the earlier of (i) the tenth day after the Shares Acquisition Date or (ii) the tenth Business Day after the date of the commencement of, or first public announcement of the intent of any Person (other than an Exempt Person) to commence, a tender or exchange offer the consummation of which would result in any Person (other than an Exempt Person) becoming the Beneficial Owner of Common Shares aggregating 15% or more of the then outstanding Common Shares of the Company (the earlier of (i) and (ii) being herein referred to as the “ Distribution Date ”), (x) the Rights (unless earlier expired, redeemed or terminated) will be evidenced (subject to the provisions of Section 3.2) by the certificates for Common Shares registered in the names of the holders thereof (which certificates for Common Shares shall also be deemed to be Right Certificates) and not by separate certificates, and (y) the Rights (and the right to receive certificates therefor) will be transferable only in connection with the transfer of the underlying Common Shares. The preceding sentence notwithstanding, prior to the occurrence of a Distribution Date specified as a result of an event described in clause (ii) (or such later Distribution Date as the Board of Directors of the Company may select pursuant to this sentence), the Board of Directors may postpone, one or more times, the Distribution Date which would occur as a result of an event described in clause (ii) beyond the date set forth in such clause (ii). The Company shall promptly notify the Rights Agent in writing of any such postponement. Nothing herein shall permit such a postponement of a Distribution Date after a Person becomes an Acquiring Person, except as a result of the operation of the third sentence of Section 1.1. As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign and the Company (or, if requested and provided with all necessary information, the Rights Agent) will send, by first-class, insured, postage-prepaid mail, to each record holder of Common Shares as of the close of business on the Distribution Date (other than any Acquiring Person or any Associate or Affiliate of an Acquiring Person), at the address of such holder shown on the records of the Company, one or more certificates for Rights, in substantially the form of Exhibit B hereto (a “ Right Certificate ”), evidencing one Right (subject to adjustment as provided herein) for each Common Share so held. As of the Distribution Date, the Rights will be evidenced solely by such Right Certificates. The Company shall promptly notify the Rights Agent in writing upon the occurrence of the Distribution Date and, if such notification is given orally, the Company shall confirm same in writing on or prior to the Business Day next following. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Distribution Date has not occurred.

6

3.2.  Summary of Rights . On the Record Date or as soon as practicable thereafter, the Company will send or cause to be sent a copy of a Summary of Rights to Purchase Preferred Shares, in substantially the form attached hereto as Exhibit C (the “ Summary of Rights ”), by first-class, postage-prepaid mail, to each record holder of Common Shares as of the close of business on the Record Date at the address of such holder shown on the records of the Company. With respect to certificates for Common Shares outstanding as of the close of business on the Record Date, until the Distribution Date (or the earlier Expiration Date), the Rights will be evidenced by such certificates for Common Shares registered in the names of the holders thereof together with a copy of the Summary of Rights and the registered holders of the Common Shares shall also be registered holders of the associated Rights. Until the Distribution Date (or the earlier Expiration Date), the surrender for transfer of any certificate for Common Shares outstanding at the close of business on the Record Date, with or without a copy of the Summary of Rights, shall also constitute the transfer of the Rights associated with the Common Shares represented thereby.

3.3.  New Certificates After Record Date . Certificates for Common Shares which become outstanding (whether upon issuance out of authorized but unissued Common Shares, disposition out of treasury or transfer or exchange of outstanding Common Shares) after the Record Date but prior to the earliest of the Distribution Date or the Expiration Date, shall have impressed, printed, stamped, written or otherwise affixed onto them a legend in substantially the following form:

This certificate also evidences and entitles the holder hereof to certain rights as set forth in an Agreement between Micrel, Incorporated (the “ Company ”) and Mellon Investor Services LLC, as Rights Agent, dated March 24, 2008, as the same may be amended from time to time (the “ Agreement ”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Agreement without charge after receipt of a written request therefor. As described in the Agreement, Rights which are owned by, transferred to or have been owned by Acquiring Persons or Associates or Affiliates thereof (as defined in the Agreement) shall become null and void and will no longer be transferable .

With respect to such certificates containing the foregoing legend, until the Distribution Date (or the earlier Expiration Date), the Rights associated with the Common Shares represented by such certificates shall be evidenced by such certificates alone, and the surrender for transfer of any such certificates, except as otherwise provided herein, shall also constitute the transfer of the Rights associated with the Common Shares represented thereby. In the event that the Company purchases or acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares shall be deemed canceled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Shares which are no longer outstanding.

7

Notwithstanding this Section 3.3, the omission of a legend shall not affect the enforceability of any part of this Agreement or the rights of any holder of the Rights.

Section 4. Form of Right Certificates . The Right Certificates (and the forms of election to purchase shares, certification and assignment to be printed on the reverse thereof) shall be substantially the same as Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate (but which do not affect the rights, duties or responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or trading system on which the Rights may from time to time be listed or quoted, or to conform to usage. Subject to the terms and conditions hereof, the Right Certificates, whenever issued, shall be dated as of the Record Date, and shall show the date of countersignature by the Rights Agent, and on their face shall entitle the holders thereof to purchase such number of one one-thousandths of a Preferred Share as shall be set forth therein at the price per one one-thousandth of a Preferred Share set forth therein (the “ Purchase Price ”), but the number of such one one-thousandths of a Preferred Share and the Purchase Price shall be subject to adjustment as provided herein.

Section 5. Countersignature and Registration . The Right Certificates shall be executed on behalf of the Company by its Chairman of the Board of Directors, the Chief Executive Officer, the President or any Vice President (regardless of designation), either manually or by facsimile signature, and shall have affixed thereto the Company’s seal or a facsimile thereof which shall be attested by the Secretary or any Assistant Secretary of the Company or by such officers as the Board of Directors of the Company shall designate, either manually or by facsimile signature. The Right Certificates shall be countersigned, either manually or by facsimile signature, by an authorized signatory of the Rights Agent, but it shall not be necessary for the same signatory to countersign all of the Right Certificates hereunder. No Right Certificate shall 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, and issued and delivered by the Company with the same force and effect as though the person who signed such Right Certificates had not ceased to be such officer of the Company; and any Right Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Right Certificate, shall be a proper officer of the Company to sign such Right Certificate, although at the date of the execution of this Agreement any such person was not such an officer.

Following the Distribution Date and receipt by the Rights Agent of notice to that effect and all other relevant information referred to in Section 3.1, the Rights Agent will keep or cause to be kept, at its office designated for such purpose, 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, the certificate number of each of the Right Certificates and the date of each of the Right Certificates.

8

Section 6. Transfer, Split Up, Combination and Exchange of Right Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates . Subject to the provisions of Section 11.1.2 and Section 14, 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 Right Certificates (other than Right Certificates representing Rights that have become null and void pursuant to Section 11.1.2 or that have been exchanged pursuant to Section 27) may be transferred, split up or combined or exchanged for another Right Certificate or Right Certificates, entitling the registered holder to purchase a like number of one one-thousandths of a Preferred Share as the Right Certificate or Right Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up or combine or exchange any Right Certificate shall make such request in writing delivered to the Rights Agent, and shall surrender, together with any required form of assignment and certificate duly completed, the Right Certificate or Right Certificates to be transferred, split up or combined or exchanged at the office of the Rights Agent designated for such purpose. The Right Certificates are transferable only on the registry books of the Rights Agent. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate or Right Certificates until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Right Certificate or Right Certificates and shall have 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. 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 from the holders of Right Certificates of a sum sufficient to cover any tax or charge that may be imposed in connection with any transfer, split up or combination or exchange of such Right Certificates. The Rights Agent shall have no duty or obligation to take any action under any Section of this Agreement which requires the payment by a holder of Rights of applicable taxes and charges unless and until it is satisfied that all such taxes and/or charges have been paid.

Subject to the provisions of Section 11.1.2 , at any time after the Distribution Date and prior to the Expiration Date, upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security satisfactory to them, and, at the Company’s or the Rights Agent’s request, reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Right Certificate if mutilated, the Company will make and deliver a new Right Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

7.1.  Exercise of Rights . Subject to Section 11.1.2 and except as otherwise provided herein, the registered holder of any Right Certificate may exercise the Rights evidenced thereby in whole or in part at any time after the Distribution Date upon surrender of the Right Certificate, with the form of election to purchase and certification on the reverse side thereof

7.3.  Payment Procedures . Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase and certification properly completed and duly executed, accompanied by payment of the aggregate Purchase Price for the total number of one one-thousandths of a Preferred Share to be purchased and an amount equal to any applicable tax or charge required to be paid by the holder of such Right Certificate in accordance with Section 9, in cash or by certified or cashier’s check or money order payable to the order of the Company, the Rights Agent shall thereupon promptly (i)(A) requisition from any transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent) certificates for the number of Preferred Shares to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the total number of Preferred Shares issuable upon exercise of the Rights hereunder with a depository agent, requisition from the depositary agent depositary receipts representing interests in such number of one one-thousandths of a Preferred Share as are to be purchased (in which case certificates for the Preferred Shares represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company hereby directs the depositary agent to comply with all such requests, (ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of the issuance of fractional shares in accordance with Section 14 or otherwise in accordance with Section 11.1.3, (iii) promptly after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by such holder and (iv) when appropriate, after receipt, promptly deliver such cash to or upon the order of the registered holder of such Right Certificate. In the event that the Company is obligated to issue other securities of the Company, pay cash and/or distribute other property pursuant to Section 11.1.3, 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 necessary to comply with this Agreement.

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

Section 8. Cancellation and Destruction of Right Certificates . All Right Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Rights Agent for cancellation or in canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. Subject to applicable law and regulation, the Rights Agent shall maintain in a retrievable database electronic records of all cancelled or destroyed stock certificates which have been canceled or destroyed by the Rights Agent. The Rights Agent shall maintain such electronic records or physical records for the time period required by applicable law and regulation. Upon written request of the Company (and at the expense of the Company), the Rights Agent shall provide to the Company or its designee copies of such electronic records or physical records relating to rights certificates cancelled or destroyed by the Rights Agent.

Section 9. Reservation and Availability of Capital Stock . The Company covenants and agrees that from and after the Distribution Date it will cause to be reserved and kept available out of its authorized and unissued Preferred Shares (and, following the occurrence of a Trigger Event, out of its authorized and unissued Common Shares or other securities or out of its shares held in its treasury) the number of Preferred Shares (and, following the occurrence of a Trigger Event, Common Shares and/or other securities) that will be sufficient to permit the exercise in full of all outstanding Rights.

So long as the Preferred Shares (and, following the occurrence of a Trigger Event, Common Shares and/or other securities) issuable upon the exercise of Rights may be listed on the NASDAQ Global Select Market (“ NASDAQ GSM ”) or any other national securities exchange or traded in the over-the-counter market and quoted on the National Association of Securities Dealers, Inc. Automated Quotation System (“ NASDAQ ”), the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed or admitted to trading on the NASDAQ GSM or such other exchange or quoted on the NASDAQ upon official notice of issuance upon such exercise.

The Company covenants and agrees that it will take all such action as may be necessary to ensure that all Preferred Shares (and, following the occurrence of a Trigger Event, Common Shares and/or other securities) 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.

From and after such time as the Rights become exercisable, the Company shall use its best efforts, if then necessary to permit the issuance of Preferred Shares upon the exercise of

11

Rights, to register and qualify such Preferred Shares under the Securities Act and any applicable state securities or “Blue Sky” laws (to the extent exemptions therefrom are not available), cause such registration statement and qualifications to become effective as soon as possible after such filing and keep such registration and qualifications effective until the earlier of the date as of which the Rights are no longer exercisable for such securities and the Expiration Date. The Company may temporarily suspend, for a period of time not to exceed one hundred twenty (120) days, the exercisability of the Rights in order to prepare and file a registration statement under the Securities Act and permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. The Company shall notify the Rights Agent whenever it makes a public announcement pursuant to this Section 9 and give the Rights Agent a copy of such announcement. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction unless the requisite qualification in such jurisdiction shall have been obtained and until a registration statement under the Securities Act (if required) shall have been declared effective.

The Company further covenants and agrees that it will pay when due and payable any and all taxes and governmental charges which may be payable in respect of the issuance or delivery of the Right Certificates or of any Preferred Shares (or Common Shares and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay any tax or charge which may be payable in respect of any transfer or delivery of Right Certificates to a person other than, or the issuance or delivery of certificates for the Preferred Shares (or Common Shares and/or other securities, as the case may be) 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 Preferred Shares (or Common Shares and/or other securities, as the case may be) in a name other than that of the registered holder upon the exercise of any Rights until any such tax or charge shall have been paid (any such tax or charge being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Company’s or the Right Agent’s satisfaction that no such tax or charge is due.

Section 10. Preferred Shares Record Date . Each Person in whose name any certificate for Preferred Shares (or Common Shares and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Preferred Shares (or Common Shares and/or other securities, as the case may be) represented thereby on, and such certificate 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 taxes or governmental charges) was duly made; provided , however , that if the date of such surrender and payment is a date upon which the Preferred Shares (or Common Shares and/or other securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Shares (or Common Shares and/or other securities, as the case may be) 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 holder of Preferred Shares for which the Rights shall be exercisable, including, without limitation, the right to vote or to receive dividends or other distributions, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

12

Section 11. Adjustment of Purchase Price, Number of Shares or Number of Rights . The Purchase Price, the number of Preferred Shares or other securities or property purchasable upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

11.1.  Post-Execution Events .

11.1.1.  Corporate Dividends, Reclassifications, Etc . In the event the Company shall at any time after the date of this Agreement (A) declare and pay a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine the outstanding Preferred Shares into a smaller number of Preferred Shares or (D) issue any shares of its capital stock in a reclassification of the Preferred Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11.1, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares 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 which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Shares transfer books of the Company were open, he would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. If an event occurs which would require an adjustment under both Section 11.1.1 and Section 11.1.2, the adjustment provided for in this Section 11.1.1 shall be in addition to, and shall be made prior to, the adjustment required pursuant to, Section 11.1.2.

11.1.2.  Acquiring Person Events; Triggering Events . Subject to Sections 23.1 and 27, in the event that a Trigger Event occurs, then, from and after the first occurrence of such event, each holder of a Right, except as provided below, shall thereafter have a right to receive, upon exercise thereof at a price per Right equal to the then current Purchase Price multiplied by the number of one one-thousandths of a Preferred Share for which a Right is then exercisable (without giving effect to this Section 11.1.2), in accordance with the terms of this Agreement and in lieu of Preferred Shares, such number of Common Shares as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-thousandths of a Preferred Share for which a Right is then exercisable (without giving effect to this Section 11.1.2) and (y) dividing that product by 50% of the current per share market price of the Common Shares (determined pursuant to Section 11.4) on the first of the date of the occurrence of, or the date of the first public announcement of, a Trigger Event (the “ Adjustment Shares ”); provided that the Purchase Price and the number of Adjustment Shares shall thereafter be subject to further adjustment as appropriate in accordance with Section 11.6. Notwithstanding the foregoing, upon the occurrence of a Trigger Event, any Rights that are or were acquired or Beneficially Owned by (1) any Acquiring Person or any Associate or Affiliate thereof, (2) a transferee of any Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (3) a transferee of any Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or

13

concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect avoidance of this Section 11.1.2, and subsequent transferees, shall become null and void without any further action, and any holder (whether or not such holder is an Acquiring Person or an Associate or Affiliate of an Acquiring Person) of such Rights shall thereafter have no right to exercise such Rights under any provision of this Agreement or otherwise. From and after the Trigger Event, no Right Certificate shall be issued pursuant to Section 3 or Section 6 that represents Rights that are or have become null and void pursuant to the provisions of this paragraph, and any Right Certificate delivered to the Rights Agent that represents Rights that are or have become null and void pursuant to the provisions of this paragraph shall be canceled. The Company shall give the Rights Agent written notice of the identity of any such Acquiring Person, Associate or Affiliate, or the transferee of any of the foregoing, and the Rights Agent may rely on such notice in carrying out its duties under this Agreement and shall be deemed not to have any knowledge of the identity of any such Acquiring Person, Associate or Affiliate, or the transferee of any of the foregoing unless and until it shall have received such notice.

The Company shall notify the Rights Agent when this Section 11.1.2 applies and shall use all reasonable efforts to ensure that the provisions of this Section 11.1.2 are complied with, but neither the Company nor the Rights Agent shall have any liability to any holder of Right Certificates or other Person as a result of the Company’s failure to make any determinations with respect to any Acquiring Person or its Affiliates, Associates or transferees hereunder.

From and after the occurrence of an event specified in Section 13.1, any Rights that theretofore have not been exercised pursuant to this Section 11.1.2 shall thereafter be exercisable only in accordance with Section 13 and not pursuant to this Section 11.1.2.

11.1.3.  Insufficient Shares . The Company may at its option substitute for a Common Share issuable upon the exercise of Rights in accordance with the foregoing Section 11.1.2 a number of Preferred Shares or fraction thereof such that the current per share market price of one Preferred Share multiplied by such number or fraction is equal to the current per share market price of one Common Share. In the event that upon the occurrence of a Trigger Event there shall not be sufficient Common Shares authorized but unissued, or held by the Company as treasury shares, to permit the exercise in full of the Rights in accordance with the foregoing Section 11.1.2, the Company shall take all such action as may be necessary to authorize additional Common Shares for issuance upon exercise of the Rights, provided , however , that if the Company determines that it is unable to cause the authorization of a sufficient number of additional Common Shares, then, in the event the Rights become exercisable, the Company, with respect to each Right and to the extent necessary and permitted by applicable law and any agreements or instruments in effect on the date hereof to which it is a party, shall: (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of a Right (the “ Current Value ”), over (2) the Purchase Price (such excess, the “ Spread ”) and (B) with respect to each Right (other than Rights which have become null and void pursuant to Section 11.1.2), make adequate provision to substitute for the Adjustment

14

Shares, upon payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Preferred Shares or other equity securities of the Company (including, without limitation, shares, or fractions of shares, of preferred stock which, by virtue of having dividend and liquidation rights substantially comparable to those of the Common Shares, the Board of Directors of the Company has deemed in good faith to have substantially the same value as Common Shares) (each such share of preferred stock or fractions of shares of preferred stock constituting a “ common stock equivalent ”), (4) debt securities of the Company, (5) other assets or (6) any combination of the foregoing having an aggregate value equal to the Current Value, where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected in good faith by the Board of Directors of the Company; provided , however , that if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the occurrence of a Trigger Event, then the Company shall be obligated to deliver, to the extent necessary and permitted by applicable law and any agreements or instruments in effect on the date hereof to which it is a party, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, Common Shares (to the extent available) and then, if necessary, such number or fractions of Preferred Shares (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If the Board of Directors of the Company shall determine in good faith that it is unlikely that sufficient additional Common Shares could be authorized for issuance upon exercise in full of the Rights, the thirty (30) day period set forth above may be extended and re-extended to the extent necessary, but not more than ninety (90) days following the occurrence of a Trigger Event, in order that the Company may seek shareholder approval for the authorization of such additional shares (such period as may be extended, the “ Substitution Period ”). To the extent that the Company determines that some action need be taken pursuant to the second and/or third sentences of this Section 11.1.3, the Company (x) shall provide that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended as well as a public announcement at such time as the suspension is no longer in effect and the Company shall promptly provide the Rights Agent copies of such announcements. For purposes of this Section 11.1.3, the value of a Common Share shall be the current per share market price (as determined pursuant to Section 11.4) on the date of the occurrence of a Trigger Event and the value of any “common stock equivalent” shall be deemed to have the same value as the Common Shares on such date. The Board of Directors of the Company may, but shall not be required to, establish procedures to allocate the right to receive Common Shares upon the exercise of the Rights among holders of Rights pursuant to this Section 11.1.3.

11.2.  Dilutive Rights Offering . In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred Shares entitling them (for a period expiring within forty-five (45) calendar days after such record date) to subscribe for or purchase Preferred Shares (or securities having the same rights, privileges and preferences as the Preferred Shares (“ equivalent preferred stock ”)) or securities convertible into Preferred Shares or equivalent preferred stock at a price per Preferred Share or per share of equivalent preferred

15

stock (or having a conversion or exercise price per share, if a security convertible into or exercisable for Preferred Shares or equivalent preferred stock) less than the current per share market price of the Preferred Shares (as determined pursuant to Section 11.4) 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, the numerator of which shall be the number of Preferred Shares and shares of equivalent preferred stock outstanding on such record date plus the number of Preferred Shares and shares of equivalent preferred stock which the aggregate offering price of the total number of Preferred Shares and/or shares of equivalent preferred stock to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current per share market price and the denominator of which shall be the number of Preferred Shares and shares of equivalent preferred stock outstanding on such record date plus the number of additional Preferred Shares and/or shares of equivalent preferred stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Preferred Shares and shares of equivalent preferred stock owned by or held for the account of the Company or any Subsidiary of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

11.3.  Distributions . In case the Company shall fix a record date for the making of a distribution to all holders of the Preferred Shares (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation) of evidences of indebtedness, cash, securities or assets (other than a regular periodic cash dividend at a rate not in excess of 125% of the rate of the last regular periodic cash dividend theretofore paid or, in case regular periodic cash dividends have not theretofore been paid, at a rate not in excess of 50% of the average net income per share of the Company for the four quarters ended immediately prior to the payment of such dividend, or a dividend payable in Preferred Shares (which dividend, for purposes of this Agreement, shall be subject to the provisions of Section 11.1.1(A))) or convertible securities, or subscription rights or warrants (excluding those referred to in Section 11.2), 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 per share market price of the Preferred Shares (as determined pursuant to Section 11.4) on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent) of the portion of the cash, assets, securities or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to one Preferred Share and the denominator of which shall be such current per share market price of the Preferred Shares (as determined pursuant to Section 11.4). 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 then be in effect if such record date had not been fixed.

16

11.4.  Current Per Share Market Value .

11.4.1.  General . For the purpose of any computation hereunder, the “ current per share market price ” of any security (a “ Security ” for the purpose of this Section 11.4.1) on any date shall be deemed to be the average of the daily closing prices per share of such Security for the thirty (30) consecutive Trading Days (as such term is hereinafter defined) immediately prior to but not including such date; provided , however , that in the event that the current per share market price of the Security is determined during any period following the announcement by the issuer of such Security of (i) a dividend or distribution on such Security payable in shares of such Security or securities convertible into such shares or (ii) any subdivision, combination or reclassification of such Security, and prior to the expiration of thirty (30) Trading Days after but not including the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the “current per share market price” shall be appropriately adjusted to reflect the current market price per share equivalent of such Security. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the NASDAQ GSM or, if the Security is not listed or admitted to trading on the NASDAQ GSM, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Security is listed or admitted to trading or, if the Security is not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use, or, if on any such date the Security is 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 Security selected by the Board of Directors of the Company. If on any such date no such market maker is making a market in the Security, the fair value of the Security 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 Security is listed or admitted to trading is open for the transaction of business or, if the Security is not listed or admitted to trading on any national securities exchange, a Business Day. If the Security is not publicly held or not so listed or traded, or if on any such date the Security is not so quoted and no such market maker is making a market in the Security, “current per share market price” shall mean the fair value per share as determined in good faith by the Board of Directors of the Company or, if at the time of such determination there is an Acquiring Person, by a nationally recognized investment banking firm selected by the Board of Directors, which shall have the duty to make such determination in a reasonable and objective manner, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

11.4.2.  Preferred Shares . Notwithstanding Section 11.4.1, for the purpose of any computation hereunder, the “current per share market price” of the Preferred Shares shall be determined in the same manner as set forth above in Section 11.4.1 (other than the last sentence thereof). If the current per share market price of the Preferred Shares cannot be determined in the manner described in Section 11.4.1, the “current per share market price” of the Preferred Shares shall be conclusively deemed to be an amount equal to 1,000 (as such number

17

may be appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Shares occurring after the date of this Agreement) multiplied by the current per share market price of the Common Shares (as determined pursuant to Section 11.4.1). If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, or if on any such date neither the Common Shares nor the Preferred Shares are so quoted and no such market maker is making a market in either the Common Shares or the Preferred Shares, “current per share market price” of the Preferred Shares shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, or, if at the time of such determination there is an Acquiring Person, by a nationally recognized investment banking firm selected by the Board of Directors of the Company, which shall have the duty to make such determination in a reasonable and objective manner, which determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. For purposes of this Agreement, the “current per share market price” of one one-thousandth of a Preferred Share shall be equal to the “current per share market price” of one Preferred Share divided by 1,000.

11.5.  Insignificant Changes . No adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Purchase Price. Any adjustments which by reason of this Section 11.5 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one-hundred thousandth of a Preferred Share or the nearest one-thousandth of a Common Share or other share or security, as the case may be.

11.6.  Shares Other Than Preferred Shares . If as a result of an adjustment made pursuant to Section 11.1, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than Preferred Shares, 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 Preferred Shares contained in Sections 11.1, 11.2, 11.3, 11.5, 11.8, 11.9 and 11.13, and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares shall apply on like terms to any such other shares.

11.7.  Rights Issued Prior to Adjustment . All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-thousandths of a Preferred Share purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

11.8.  Effect of Adjustments . Unless the Company shall have exercised its election as provided in Section 11.9, upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11.2 and 11.3, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one one-thousandths of a Preferred Share (calculated to the nearest one-thousand thousandth of a Preferred Share) obtained by (i) multiplying (x) the number of one one-thousandths of a Preferred Share covered by a Right immediately prior to this adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

18

11.9.  Adjustment in Number of Rights . The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in substitution for any adjustment in the number of one one-thousandths of a Preferred Share issuable upon the exercise of a Right. Each of the Rights outstanding after such adjustment of the number of Rights shall be exercisable for the number of one one-thousandths of a Preferred Share for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one-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 (with prompt written notice thereof to the Rights Agent) of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, shall be at least ten (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 11.9, the Company may, as promptly as practicable, cause to be distributed to holders of record of Right Certificates on such record date Right Certificates evidencing, subject to Section 14, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all the Rights to which 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.

11.10.  Right Certificates Unchanged . Irrespective of any adjustment or change in the Purchase Price or the number of one one-thousandths of a Preferred Share issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase Price per share and the number of one one-thousandths of a Preferred Share which were expressed in the initial Right Certificates issued hereunder.

11.11.  [Intentionally Omitted]

11.12.  Deferred Issuance . 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 (with prompt written notice thereof to the Rights Agent) until the occurrence of such event the issuance to the holder of any Right exercised after such record date of that number of Preferred Shares and shares of other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Shares and shares of other capital stock or other securities, assets or cash of the Company, if any,
