THIS RIGHTS AGREEMENT (this “Agreement”), dated as of March 23, 2011, is entered into by and between Iron Mountain Incorporated, a Delaware corporation, and Mellon Investor Services LLC (operating with the service name “BNY Mellon Shareowner Services”), a New Jersey limited liability company (the “Rights Agent”).

RECITALS

WHEREAS, on March 23, 2011, the board of directors of the Corporation (the “Board of Directors”) authorized the issuance of, and declared a dividend payable in, one right (a “Right”) for each share of common stock, par value $0.01 per share (“Common Stock”), of the Corporation outstanding as of close of business on April 1, 2011 (the “Record Date”), each such Right representing the right to purchase one one-thousandth (1/1000) of a share of Series A Junior Participating Preferred Stock of the Corporation, par value $0.01 per share (“Preferred Stock”), having the rights and preferences set forth in the form of Certificate of Designations attached hereto as Exhibit A duly adopted by the Board of Directors on March 23, 2011, upon the terms and subject to the conditions hereinafter set forth; and

WHEREAS, on March 23, 2011, the Board of Directors further authorized the issuance of one Right (subject to adjustment) with respect to each share of Common Stock which may be issued between the Record Date and the earliest to occur of the Distribution Date, the Expiration Date or the Final Expiration Date (as such terms are hereinafter defined); provided, however, that Rights may be issued with respect to shares of Common Stock that shall become outstanding after the Distribution Date and prior to the earlier of the Expiration Date and the Final Expiration Date in accordance with Section 22 hereof.

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 shall have the meanings provided in this Section 1.  Any capitalized term defined in this Section 1 and used in the following definitions shall have the meaning provided in this Section 1.

(a)                                  “Acquiring Person” shall mean any Person (as such term is hereinafter defined) who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner (as such term is hereinafter defined) of fifteen percent (15%) or more of the shares of Voting Stock then outstanding, but shall not include an Exempt Person (as such term is hereinafter defined); provided, however, that (i) if the Board of Directors determines in good faith that a Person became the Beneficial Owner of a number of shares of Voting Stock such that the Person would otherwise qualify as an “Acquiring Person” inadvertently (including, without limitation, because

(A) such Person was unaware that it Beneficially Owned a percentage of Voting Stock 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 Voting 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 Corporation, then such Person shall not be deemed to be or to have become an “Acquiring Person” for any purposes of this Agreement unless and until such Person shall have failed to divest itself, as soon as practicable (as determined, in good faith, by the Board of Directors), of Beneficial Ownership of a sufficient number of shares of Voting Stock so that such Person would no longer otherwise qualify as an “Acquiring Person” (or, in the case solely of Derivative 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 Shares are not held with any intention of changing or influencing control of the Corporation); (ii) an Existing Holder (as such term is hereinafter defined) shall not be deemed to be or to become an “Acquiring Person” unless and until such time as such Existing Holder shall become the Beneficial Owner of additional shares of Voting Stock representing one-quarter of one percent (0.25%) of the then-outstanding Voting Stock (other than pursuant to a dividend or distribution paid or made by the Corporation on the outstanding Voting Stock or pursuant to a split or subdivision of the outstanding Voting Stock); provided, however, that if, following the date hereof, any Existing Holder Beneficially Owns less than fifteen percent (15%) of the Voting Stock then outstanding, such Existing Holder shall thereafter become an Acquiring Person if such Existing Holder acquires Beneficial Ownership of additional shares of Voting Stock representing fifteen percent (15%) or more of the Voting Stock then outstanding (other than pursuant to a dividend or distribution paid or made by the Corporation on the outstanding Voting Stock or pursuant to a split or subdivision of the outstanding Voting Stock); and (iii) no Person shall become an “Acquiring Person” as the result of an acquisition of shares of Voting Stock by the Corporation which, by reducing the number of shares outstanding, increases the proportionate number of shares of Voting Stock beneficially owned by such Person so that such Person would otherwise become an “Acquiring Person”; provided, however, that if any such Person shall thereafter become the Beneficial Owner of additional shares of Voting Stock representing one-quarter of one percent (0.25%) of the then-outstanding Voting Stock (other than pursuant to a dividend or distribution paid or made by the Corporation on the outstanding Voting Stock or pursuant to a split or subdivision of the outstanding Voting Stock), then such Person shall be deemed to be an “Acquiring Person” unless upon becoming the Beneficial Owner of such additional shares of Voting Stock such Person does not beneficially own fifteen percent (15%) or more of the shares of Voting Stock then outstanding.  For all purposes of this Agreement, any calculation of the number of shares of Voting Stock outstanding at any particular time, including for purposes of determining the particular percentage of such outstanding shares of Voting Stock of which any Person is the Beneficial Owner, shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act, as in effect on the date hereof.

(d)                                 A person shall be deemed the “Beneficial Owner” of, to “Beneficially Own” or have “Beneficial Ownership” of any securities (and correlative terms shall have correlative meanings):

(i)                                     which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or indirectly, for purposes of Section 13(d) of the Exchange Act and Regulations 13D and 13G thereunder, in each case, as in effect on the date of this Agreement;

(ii)                                  which such Person or any of such Person’s Affiliates or Associates has (A) the right to acquire (whether such right is exercisable immediately or only after the passage of time or the fulfillment of a condition or both) pursuant to any agreement, arrangement or understanding (whether or not in writing), or upon the exercise of conversion rights, exchange rights, other rights (other than the Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, to Beneficially Own or have Beneficial Ownership of, securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange or (B) the right to vote, alone or in concert with others, 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, to Beneficially Own or have Beneficial Ownership of, any securities if the agreement, arrangement or understanding to vote such security (1) arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made pursuant to, and in accordance with, the

3

applicable rules and regulations under the Exchange Act and (2) is not at the time reportable by such Person on a Schedule 13D report under the Exchange Act (or any comparable or successor report), other than by reference to a proxy or consent solicitation being conducted by such Person;

(iii)                               which are beneficially owned, directly or indirectly, by any other Person with which such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (whether or not in writing) for the purpose of acquiring, holding, voting (except as described in clause (B) of subparagraph (ii) of this paragraph (d)) or disposing of any securities of the Corporation; provided, however, that for purposes of determining Beneficial Ownership of securities under this Agreement, officers and directors of the Corporation, solely by reason of their status as such, shall not constitute a group (notwithstanding that they may be Associates of one another or may be deemed to constitute a group for purposes of Section 13(d) the Exchange Act) and shall not be deemed to own securities owned by another officer or director of the Corporation; or

(iv)                              which are the subject of, or the reference securities for, or that underlie any derivative transaction entered into by such Person, or derivative security (including options) 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 directly or indirectly 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 shares of Voting Stock deemed Beneficially Owned by virtue of the operation of this Section 1(d)(iv), the subject Person shall be deemed to Beneficially Own (without duplication) the number of shares of Voting Stock that are synthetically owned pursuant to such derivative transactions or such derivative securities.  Such shares of Voting Stock that are deemed so Beneficially Owned pursuant to the operation of this Section 1(d)(iv) shall be referred to herein as “Derivative Shares”.

Notwithstanding anything in this paragraph (d) to the contrary, a Person engaged in the business of underwriting securities in the ordinary course of its business shall not be deemed the Beneficial Owner of, to Beneficially Own or to have Beneficial Ownership of, any securities acquired or otherwise beneficially owned in good faith in a firm commitment underwriting until the expiration of forty (40) days after the date of the sale of securities to the public pursuant to such firm commitment underwriting.

(a)           On the Record Date (or as soon as practicable thereafter), the Corporation will send or cause to be sent a copy of a Summary of Rights, in substantially the form attached hereto as Exhibit B (the “Summary of Rights”), by first class mail, postage prepaid, to each record holder of the Common Stock as of the Record Date, at the address of such holder shown on the records of the Corporation or the transfer agent or registrar for Common Stock.

(b)           Until the Close of Business on the day which is the earlier of (i) the tenth (10th) Business Day after the Stock Acquisition Date or (ii) the tenth (10th) Business Day (or such later date as may be determined by action of the Board of Directors prior to such time as any Person becomes an Acquiring Person) after the date of the commencement by any Person (other than an Exempt Person) of a tender or exchange offer upon the successful consummation of which such Person, or any Affiliate or Associate of such Person, would be an Acquiring Person (including any such date 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”), (A) the Rights shall be evidenced by the certificates for Common Stock (or in the case of uncertificated shares of Common Stock, by the book-entry account that evidences record ownership for such shares) registered in the names of the holders of Common Stock (together with, in the case of certificates for Common Stock outstanding as of the Record Date, the Summary of Rights) and not by separate Right certificates, and the record holders of such certificates (or such book-entry accounts) for Common Stock shall be the record holders of the Rights represented thereby and (B) each Right shall only be transferable simultaneously and together with the transfer of a share of Common Stock (subject to adjustment as hereinafter provided).  Until the Distribution Date (or, if earlier, the Expiration Date or Final Expiration Date), the surrender for transfer of any certificate for Common Stock (or the effectuation of a book-entry transfer of shares of Common Stock) shall constitute the surrender for transfer of the Right or Rights associated with the Common Stock evidenced thereby, whether or not accompanied by a copy of the Summary of Rights.

(c)           Rights shall be issued in respect of all shares of Common Stock that become outstanding after the Record Date, but prior to the earliest of the Distribution Date, the Expiration Date or the Final Expiration Date.  Certificates that become outstanding (including, without limitation, certificates issued upon original issuance, disposition from the Corporation’s treasury or transfer or exchange of Common Stock) after the Record Date but prior to the earliest of the Distribution Date, the Expiration Date, or the Final Expiration Date, shall have impressed, printed, written or stamped thereon or otherwise affixed thereto substantially the following legend:

This certificate also evidences and entitles the holder hereof to the same number of Rights (subject to adjustment) equal to the number of shares of common stock represented by this certificate, such Rights being on the terms set forth in the Rights Agreement by and between Iron Mountain Incorporated (the “Corporation”) and

8

Mellon Investor Services LLC (operating with the service name “BNY Mellon Shareowner Services”) (the “Rights Agent”), dated as of March 23, 2011, as it may be amended from time to time (the “Agreement”), the terms of which are incorporated herein by reference and a copy of which is on file at the principal executive offices of the Corporation.  Under certain circumstances, as set forth in the Agreement, such Rights may be redeemed, may become exercisable for securities or assets of the Corporation, or securities of another entity, may be exchanged for shares of Common Stock or other securities or assets of the Corporation or may expire. Under certain circumstances, as set forth in the Agreement, such Rights shall be evidenced by separate certificates and shall no longer be evidenced by this certificate.  The Corporation shall mail to the registered holder of this certificate a copy of the Agreement without charge within five (5) days after receipt of a written request therefor.  As provided in Section 7(e) of the Agreement, Rights issued to or Beneficially Owned by Acquiring Persons or their Affiliates or Associates (as such terms are defined in the Agreement) or any subsequent holder of such Rights shall be null and void and may not be exercised by or transferred to any Person.

With respect to any book-entry shares of Common Stock, such legend shall be included in a notice to the record holder of such shares in accordance with applicable law.  With respect to such certificates containing the foregoing legend, or any notice of the foregoing legend delivered to holders of book-entry shares, until the Distribution Date, the Rights associated with the Common Stock represented by such certificates or registered in book-entry form shall be evidenced by such certificates alone or such registration in book-entry form, and the surrender for transfer of any such certificate or book-entry shares, except as otherwise provided herein, shall also constitute the transfer of the Rights associated with the Common Stock.  In the event that the Corporation purchases or otherwise acquires any shares of Common Stock after the Record Date but prior to the Distribution Date, any Rights associated with such shares of Common Stock shall be deemed canceled and retired so that the Corporation shall not be entitled to exercise any Rights associated with the shares of Common Stock that are no longer outstanding.  Notwithstanding this paragraph (c), neither the omission of a legend, nor the failure to provide notice thereof, shall affect the enforceability of any part of this Agreement or the rights of any holder of the Rights.

(d)           As soon as practicable after the Distribution Date, the Corporation will prepare and execute, the Rights Agent will countersign, and the Corporation will send or cause to be sent (and the Rights Agent will, if requested by the Corporation and provided with a shareholder list and all necessary or relevant information and documents,

9

at the Corporation’s expense, send), by first class mail, postage prepaid, to each record holder of the Common Stock as of the Close of Business on the Distribution Date, as shown by the records of the Corporation or the transfer agent or registrar for Common Stock, at the address of such holder shown on such records, a certificate substantially in the form provided by Section 4 hereof (a “Right Certificate”), evidencing one Right (subject to adjustment as provided herein) for each share of Common Stock so held.  As of and after the Distribution Date, the Rights shall be evidenced solely by Right Certificates and may be transferred by the transfer of the Right Certificate as permitted hereby, separately and apart from any transfer of one or more shares of Common Stock.

Section 4.               Form of Right Certificates.  The Right Certificates (and the forms of election to purchase shares, certificate and assignment to be printed on the reverse thereof), when, as and if issued, shall be substantially in the form set forth in Exhibit C hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as may be required to comply with any law or any applicable rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Common Stock or the Rights may from time to time be listed or as the Corporation may deem appropriate (but which do not affect the rights, duties, liabilities or responsibilities of the Rights Agent) to conform to usage or otherwise and as are not inconsistent with the provisions of this Agreement.  Subject to the provisions of Section 22 hereof, Right Certificates evidencing Rights whenever issued, (a) shall be dated as of the date of issuance of the Rights they represent and (b) subject to adjustment from time to time as provided herein, on their face shall entitle the holders thereof to purchase such number of one one-thousandths (1/1000) of a share (including fractional shares which are integral multiples of one one-thousandth (1/1000) of a share) of Preferred Stock as shall be set forth thereon at the price per one one-thousandth (1/1000) of a share of Preferred Stock payable upon exercise of a Right provided by Section 7(b) hereof, as the same may from time to time be adjusted as provided herein (the “Exercise Price”).

Section 5.               Countersignature and Registration.

(a)           Each Right Certificate shall be executed on behalf of the Corporation by its Chief Executive Officer, President or any Executive Vice President, either manually or by facsimile signature, and have affixed thereto the Corporation’s seal or a facsimile thereof which shall be attested to by the Secretary or an Assistant Secretary of the Corporation, either manually or by facsimile signature.  Each Right Certificate shall be countersigned by the Rights Agent either manually or by facsimile signature and shall not be valid for any purpose unless so countersigned.  In case any officer of the Corporation who shall have signed any Right Certificate shall cease to be such officer of the Corporation before countersignature by the Rights Agent and issuance and delivery of the Right Certificate by the Corporation, such Right Certificate, nevertheless, may be countersigned by the Rights Agent and 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 Corporation.  Any Right Certificate may be signed on behalf of the Corporation by any person who, on the date of the execution of such Right Certificate,

10

shall be a proper officer of the Corporation to sign such Right Certificate, although at the date of the execution of this Agreement any such person was not such an officer.

(b)           Following the Distribution Date and upon receipt by the Rights Agent of notice of the Distribution Date and all other relevant information and documents referred to in Section 3(d), the Rights Agent shall keep or cause to be kept, at the office of the Rights Agent 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 the face of 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 Sections 7(e), 7(f) and 14 hereof, at any time after the Close of Business on the Distribution Date, and at or prior to the Close of Business on the earlier of the Expiration Date or the Final Expiration Date, any Right Certificate (other than Right Certificates representing Rights that have become null and void pursuant to Section 11 hereof or that have been exchanged pursuant to Section 27 hereof), may be (i) transferred or (ii) split up, combined or exchanged for one or more other Right Certificates, entitling the registered holder to purchase a like number of one one-thousandths (1/000) of a share of Preferred Stock as the Right Certificate surrendered then entitled such holder to purchase.  Any registered holder desiring to transfer, split up, combine or exchange any Right Certificate or Right Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Right Certificate at the office of the Rights Agent designated for such purpose with the form of certificate and assignment on the reverse side thereof duly endorsed (or enclose with such Right Certificate a written instrument of transfer in form satisfactory to the Corporation and the Rights Agent), duly executed by the registered holder thereof or his attorney duly authorized in writing, and with such signature duly guaranteed and such other and further documentation as the Rights Agent or the Corporation may require.  The Right Certificates are transferable only on the registry books of the Rights Agent.  Neither the Rights Agent nor the Corporation shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate until the registered holder shall have (i) properly completed and duly executed the certificate contained in the form of assignment set forth on the reverse side of such Right Certificate, (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) from whom the Rights evidenced by such Right Certificate are to be transferred (or the Beneficial Owner to whom such Rights are to be transferred) or Affiliates thereof as the Corporation or the Rights Agent shall reasonably request, and (iii) paid a sum sufficient to cover any Transfer Tax that may be imposed in connection with any transfer, split up combination or exchange of Rights Certificates.  Thereupon, subject to Sections 5, 7(f) and 14 hereof, the Corporation shall execute and 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, registered in such name or names as may be designated by the surrendering registered holder.  The Rights Agent shall forward any such sum collected

11

by it to the Corporation or to such Persons as the Corporation shall specify by written notice.  The Rights Agent shall have no duty or obligation under any Section of this Agreement that requires the payment of Transfer Taxes unless and until it is satisfied that all such Transfer Taxes have been paid in full.

(b)           Subject to the provisions of Sections 7(e), 7(f) and 14 hereof, at any time after the Distribution Date and prior to the Close of Business on earlier of the Expiration Date and the Final Expiration Date, upon receipt by the Corporation and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security satisfactory to them and, if requested by the Corporation or Rights Agent, reimbursement to the Corporation and the Rights Agent of all reasonable expenses incidental thereto, or upon surrender to the Rights Agent and cancellation of the Right Certificate if mutilated, accompanied by a signature guarantee and such other and further documentation as the Rights Agent may require, the Corporation shall cause a new Right Certificate of like tenor to be issued and delivered to the registered owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

Section 7.               Exercise of Rights; Exercise Price; Expiration Date of Rights; Invalidation of Certain Rights.

(a)           The Rights shall not be exercisable until, and shall become exercisable on, the Distribution Date (unless otherwise provided herein, including, without limitation, the restrictions on exercisability set forth in Section 7(e), 23(a) and 27(b) hereof).  Except as otherwise provided herein, the Rights may be exercised, in whole or in part, at any time commencing with the Distribution Date upon surrender of the Right Certificate, with the form of election to purchase and certificate on the reverse side thereof properly completed and duly executed (with signatures duly guaranteed), to the Rights Agent at the designated office for such purpose of the Rights Agent, accompanied by a signature guarantee and such other documentation as the Rights Agent may require, and together with payment in cash, only by electronic or wire transfer, or by certified check or bank check, of the Exercise Price (which payment shall include any additional amount payable by such Person in accordance with Section 9 hereof) for each Right exercised (as the same may have been adjusted as hereinafter provided), at or prior to the Close of Business on the earliest to occur of (i) March 22, 2013 (the “Final Expiration Date”), (ii) the date on which the Rights are redeemed as provided in Section 23 hereof or the date on which the Rights are exchanged as provided in Section 27 hereof or (iii) the date of the Corporation’s 2012 annual meeting of stockholders if Stockholder Approval has not been obtained at such meeting (such earliest date being herein referred to as the “Expiration Date”).

(b)           The Exercise Price shall initially be $120.00 for each one one-thousandth (1/1000) of a share of Preferred Stock issued pursuant to the exercise of a Right.  The Exercise Price and the number of one one-thousandths (1/1000) of a share of Preferred Stock or other securities or property to be acquired upon exercise of a Right shall be subject to adjustment from time to time as provided in Sections 11 and 13 hereof.

12

The Exercise Price shall be payable in lawful money of the United States of America, in accordance with paragraph (c) below.

(c)           Except as otherwise provided herein, upon receipt of a Right Certificate representing exercisable Rights with the form of election to purchase and certificate contained therein properly completed and duly executed, accompanied by full payment by certified check, cashier’s check, bank draft or money order payable to the Corporation or the Rights Agent of the aggregate Exercise Price for the number of one one-thousandths (1/1000) of a share of Preferred Stock to be purchased and an amount equal to any applicable Transfer Tax required to be paid by the holder of the Right Certificate in accordance with Section 9(e) hereof, the Rights Agent shall, subject to Sections 7(a), 11 and 20, thereupon promptly (i) request from any transfer agent of the Preferred Stock of the Corporation (or from the Corporation, if there shall be no such transfer agent, or make available if the Rights Agent is such transfer agent) one or more certificates representing the number of shares of Preferred Stock to be so purchased, and the Corporation hereby authorizes and directs any such transfer agent to comply with all such requests, (ii) as provided in Section 14(b) hereof, at the election of the Corporation, cause depositary receipts to be issued in lieu of fractional shares of Preferred Stock, and the Corporation hereby directs such depositary agent to comply with all such requests, (iii) if the election provided for in the immediately preceding clause (ii) has not been made, request from the Corporation the amount of cash to be paid in lieu of the issuance of fractional shares (other than fractions that are integral multiples of one one-thousandth (1/1000) of a share) in accordance with Section 14(b) hereof, (iv) after receipt of such Preferred Stock certificates and, if applicable, 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 (v) when appropriate, after receipt, deliver such cash to or upon the order of the registered holder of such Right Certificate; provided, however, that in the case of a purchase of securities other than Preferred Stock, pursuant to Section 13 hereof, the Rights Agent shall take the appropriate actions corresponding in such case to that referred to in the foregoing clauses (i) through (v) of this Section 7(c).  For purposes of this Section 7, the Rights Agent shall be entitled to rely, and shall be protected in relying, on a certificate duly executed by an officer of the Corporation to the effect that the Distribution Date has occurred.  Notwithstanding the foregoing provisions of this Section 7(c), the Corporation may suspend (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may presume conclusively that no such suspension has occurred) the issuance of shares of Preferred Stock and other securities upon exercise of a Right for a reasonable period, not in excess of ninety (90) days, during which the Corporation seeks to register under the Securities Act, and any applicable securities law of any other jurisdiction, the shares of Preferred Stock or other securities to be issued pursuant to the Rights; provided, however, that nothing contained in this Section 7(c) shall relieve the Corporation of its obligations under Section 9(d) hereof.  Upon any such suspension, the Corporation shall issue a public announcement (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such

13

suspension has occurred) stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such lifting of such suspension has occurred) at such time as the suspension is no longer in effect.

(d)           In case the registered holder of any Right Certificate shall exercise less than all the Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued and delivered by the Corporation to the Rights Agent and countersigned and delivered by the Rights Agent to the registered holder of such Right Certificate or his duly authorized assign, subject to the provisions of Section 14(b) hereof.

(e)           Notwithstanding any provision of this Agreement to the contrary, from and after the time (the “invalidation time”) when any Person first becomes an Acquiring Person, any Rights that are Beneficially Owned by (i) such Acquiring Person (or any Associate or Affiliate of such Acquiring Person), (ii) a transferee of such Acquiring Person (or any such Associate or Affiliate) who becomes a transferee after the invalidation time or (iii) a transferee of such Acquiring Person (or any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the invalidation time pursuant to either (A) a transfer from the Acquiring Person (or any such Associate or Affiliate) to holders of its equity securities or to any Person with whom it has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors has determined is part of a plan, arrangement or understanding which has the purpose or effect of avoiding the provisions of this Section 7(e), and subsequent transferees of such Persons referred to in clauses (ii) and (iii) above, shall be null and void without any further action and any holder of such Rights shall thereafter have no rights whatsoever with respect to such Rights under any provision of this Agreement.  No Right Certificate shall be issued pursuant to Section 3 hereof that represents Rights beneficially owned by an Acquiring Person or any Affiliate or Associate thereof whose Rights would be null and void pursuant to the provisions of this Section 7(e), no Right Certificate shall be issued at any time upon the transfer of any Rights to an Acquiring Person (or an Affiliate or Associate of such Acquiring Person) whose Rights would be null and void pursuant to the provisions of this Section 7(e) or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate, and any Right Certificate delivered to the Rights Agent for transfer to an Acquiring Person (or an Associate or Affiliate of such Acquiring Person) whose Rights would be null and void pursuant to the provisions of this Section 7(e) shall be cancelled.  The Corporation shall use all reasonable efforts to ensure that the provisions of this Section 7(e) are complied with, but neither it nor the Rights Agent shall have any liability to any holder of Right Certificates or any other Person as a result of any failure to make any determination with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder.

(f)            Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Corporation shall be obligated to undertake any action

14

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) duly and properly completed and signed the certificate following 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 and such other information as the Corporation or the Rights Agent shall reasonably request.

Section 8.               Cancellation and Destruction of Right Certificates.  All Right Certificates surrendered for the purpose of and accepted for exercise, transfer, split up, combination or exchange shall, if surrendered to the Corporation or to any of its agents (other than the Rights Agent), 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 Agreement.  The Corporation shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall cancel and retire, any Right Certificate purchased or acquired by the Corporation other than in connection with the exercise thereof.  The Rights Agent shall deliver all cancelled Right Certificates to the Corporation, or shall, at the written request of the Corporation, destroy such cancelled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Corporation.

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

(a)           The Corporation covenants and agrees that it will cause to be reserved and kept available out of the authorized and unissued shares of Preferred Stock or out of authorized and issued shares of Preferred Stock held in its treasury, such number of shares of Preferred Stock as will from time to time be sufficient to permit the exercise in full of all outstanding Rights.

(b)           The Corporation shall use its reasonable best efforts to cause, from and after such time as the Rights become exercisable, all shares of Preferred Stock issued or reserved for issuance in accordance with this Agreement to be listed, upon official notice of issuance, upon the principal national securities exchange, if any, upon which the Common Stock is listed or, if the principal market for the Common Stock is not on any national securities exchange, to be eligible for or admitted to trading on any quotation or other system then in use.

(c)           The Corporation covenants and agrees that it will take all such action as may be necessary to ensure that all shares of Preferred Stock delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the full Exercise Price in respect thereof), be duly and validly authorized and issued and fully paid and nonassessable shares.

(d)           The Corporation shall use its reasonable best efforts to (i) file, as soon as practicable following the occurrence of the event described in Section 11(a)(ii),

15

or as soon as is required by law following the Distribution Date, as the case may be, a registration statement under the Securities Act and the Exchange Act on an appropriate form, with respect to the shares of Preferred Stock purchasable upon exercise of the Rights, (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 Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for Preferred Stock and (B) the earlier of the Expiration Date and the Final Expiration Date.  The Corporation may temporarily suspend (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such suspension has occurred), for a period of time not to exceed ninety (90) days, the issuance of shares of Preferred Stock upon exercise of a Right in order to prepare and file a registration statement under the Securities Act and permit it to become effective.  The Corporation shall 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.  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.

(e)           The Corporation covenants and agrees that it will pay when due and payable any and all United States federal and state Transfer Taxes which may be payable in respect of the issuance or delivery of the Right Certificates or of any shares of Preferred Stock issued or delivered upon the exercise of Rights.  The Corporation shall not, however, be required to pay any Transfer Tax which may be payable in respect of any transfer or delivery of a Right Certificate to a Person other than, or the issuance or delivery of certificates for Preferred Stock upon exercise of Rights in a name other than that of, the registered holder of the Right Certificate, and the Corporation shall not be required to issue or deliver a Right Certificate or certificate for Preferred Stock to a Person other than such registered holder until any such Transfer Tax shall have been paid (any such Transfer Tax being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Corporation’s or the Rights Agent’s satisfaction that no such Transfer Tax is due.

(f)            The requirements of this Section 9 shall apply to shares of Common Stock of the Corporation if the Corporation has elected in accordance with Section 11(a)(iii) hereof to substitute shares of Common Stock for shares of Preferred Stock that otherwise may be purchased upon the exercise of Rights.

Section 10.             Preferred Stock Record Date.  Each Person in whose name any certificate for shares of Preferred Stock is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Preferred Stock represented thereby on, and such certificate shall be dated as of, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the full Exercise Price (and any applicable Transfer Taxes) was duly made; provided, however,

16

that, if the date of such surrender and payment is a date upon which the relevant Preferred Stock transfer books are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated as of, the next succeeding Business Day on which such Preferred Stock transfer books are open.

Section 11.             Adjustment of Exercise Price or Number of Shares.

(a)           The Exercise Price and the number of shares of Preferred Stock which may be purchased upon exercise of a Right are subject to adjustment from time to time as provided in this Section 11.

(i)  In the event the Corporation shall at any time after the date of this Agreement (A) declare or pay any dividend on Common Stock payable in shares of Common Stock, (B) subdivide or split the outstanding shares of Common Stock into a greater number of shares or (C) combine or consolidate the outstanding shares of Common Stock into a smaller number of shares or effect a reverse split of the outstanding shares of Common Stock, then and in each such event the number of one one-thousandths (1/1000) of a share of Preferred Stock issuable upon the exercise of a Right after the record date for such event (if one shall have been established or, if not, after the date of such event) shall be the number of one one-thousandths (1/1000) of a share of Preferred Stock issuable immediately prior to such event multiplied by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which is the number of shares of Common Stock outstanding immediately after such event, and the Exercise Price to be in effect after the record date for such event (if one shall have been established or, if not, after the date of such event) shall be determined by multiplying the Exercise Price in effect immediately prior to such event by such fraction.  If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii).

(ii)           Subject to Section 27 hereof, in the event that any Person shall become an Acquiring Person, then, subject to the last sentence of Section 23(a) hereof and except as otherwise provided in this Section 11, each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive upon exercise of such Right in accordance with the terms of this Agreement and payment of the Exercise Price, such number of one one-thousandths (1/1000) of a share of Preferred Stock as shall equal the result obtained by (A) multiplying the then current Exercise Price by the number of one one-thousandths (1/1000) of a share of Preferred Stock for which a Right would, absent adjustment pursuant to this Section 11(a)(ii), be then exercisable and dividing the product by (B) fifty percent (50%) of the proportionate Fair Market Value of one one-thousandth (1/1000) of a share of Preferred Stock (determined pursuant to Section 11(b) hereof) on the Stock Acquisition Date in respect of such event; provided, however, 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).

17

(iii)          In the event that the Corporation does not have available sufficient authorized but unissued shares of Preferred Stock to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii), the Corporation shall take all such action as may be necessary to authorize and reserve for issuance such number of additional shares of Preferred Stock as may from time to time be required to be issued upon the exercise in full of all Rights from time to time outstanding and, if necessary, shall use its reasonable best efforts to obtain stockholder approval thereof.  In lieu of issuing shares of Preferred Stock in accordance with the foregoing subparagraph (ii), the Corporation may, if the Board of Directors determines that such action is necessary or appropriate, elect to issue or pay, upon the exercise of the Rights, cash, property, shares of Preferred Stock or Common Stock, or any combination thereof, having an aggregate Fair Market Value equal to the Fair Market Value of the shares of Preferred Stock which otherwise would have been issuable pursuant to Section 11(a)(ii) hereof as of the date the Board of Directors makes such election (which Fair Market Value shall be determined as provided by Section 11(b) hereof).  Subject to Section 23 hereof, any such election by the Board of Directors must be made and publicly announced within thirty (30) days after the date on which the event described in Section 11(a)(ii) occurs and shall be applicable with respect to all Rights exercised after such public announcement.  Notice of such election shall promptly be given to the Rights Agent.  The Rights Agent may conclusively assume that no such election has been made until it receives such notice.

(b)           For the purpose of this Agreement, the “Fair Market Value” of any share of Preferred Stock, Common Stock or any other stock or any Right or other security or any other property on any date shall be determined as provided in this Section 11(b).  In the case of a publicly traded (as such term is hereinafter defined) stock or other security, the Fair Market Value thereof on any date shall be deemed to be the average of the daily closing prices per share of such stock or per unit of such other 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 Fair Market Value of any share of Common Stock is to be determined as of a date that is within thirty (30) Trading Days after but not including (i) the ex-dividend date for a dividend or distribution on the Common Stock payable in shares of Common Stock or securities convertible into shares of Common Stock or (ii) the effective date of any subdivision, split, combination, consolidation, reverse stock split or reclassification of the Common Stock, then, and in each such case, the Fair Market Value shall be appropriately adjusted by the Board of Directors to take into account such dividend, distribution, subdivision, split, combination, consolidation, reverse stock split or reclassification.  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 applicable transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange), or, if the securities are not listed or admitted to trading on the New York Stock Exchange, as reported in the applicable transaction reporting system with respect to securities listed on the principal national securities exchange (which, if approved by the Board of Directors,

18

may be a securities exchange of a country other than the United States of America) on which such security is listed or admitted to trading, or, if not listed or admitted to trading on any such 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 quotation reporting system then in use in the United States of America, or, if no bids for such security are so quoted, the average of the closing bid and asked prices as furnished by a professional market maker making a market in such security selected by the Board of Directors.  The term “Trading Day” shall mean a day on which the principal national securities exchange on which such security is listed or admitted to trading is open for the transaction of business or, if such security is not listed or admitted to trading on any national securities exchange, a Business Day.  For purposes of this Section 11(b), a stock or other security shall be considered “publicly traded” only (i) if registered under Section 12 of the Exchange Act or exempt from such registration pursuant to Section 12(g)(2)(B), (C) or (G) of the Exchange Act, (ii) if traded on a national securities exchange of a country other than the United States of America approved by the Board of Directors or (iii) if, in the judgment of the Board of Directors, there is sufficient active trading in such stock or other security that reported trading transactions therein fairly reflect the fair market value thereof.  If a security is not publicly traded, “Fair Market Value” shall mean the fair value per share of stock or per other unit of such other security, as determined by an independent investment banking firm experienced in the valuation of securities selected in good faith by the Board of Directors, or, if no such investment banking firm is, in the good faith judgment of the Board of Directors, available to make such determination, as determined in good faith by the Board of Directors; provided, however, that for purposes of making the adjustment provided for by Section 11(a)(ii) hereof, the Fair Market Value of a share of Preferred Stock, unless the Preferred Stock shall at the time be publicly traded (in which case its Fair Market Value shall be determined pursuant to the foregoing provisions of this Section 11(b)), shall be 100% of the product of the Fair Market Value of a share of Common Stock multiplied by the higher of the then Dividend Multiple or Vote Multiple applicable to the Preferred Stock (as defined in the certificate of designations of the Corporation relating to the Preferred Stock); provided, further, however, that the Board of Directors may, by resolution, determine that the Fair Market Value of a share of Preferred Stock shall be more than such amount but not more than 110% of the product of the then Fair Market Value of a share of Common Stock multiplied by the higher of the then Dividend Multiple or Vote Multiple applicable to the Preferred Stock.  In the case of property other than securities, the Fair Market Value thereof shall be determined in good faith by the Board of Directors based upon such appraisals or valuation reports of such independent experts as the Board of Directors shall in good faith determine to be appropriate in accordance with good business practices and fair to the interests of the holders of Rights.  Any determination made by the Board of Directors as provided for by this Section 11(b) shall be described in a written statement filed by the Corporation with the Rights Agent, shall be effective thereupon and only thereupon and shall be binding upon the Rights Agent and, as provided by and subject to Section 34 hereof, all holders of Rights.  The Rights Agent may be conclusively assumed to have no knowledge of any

19

such determination until it receives such statement and may conclusively rely on such statement.

(c)           In case the Corporation shall fix a record date for the issuance of rights, options or warrants to all holders of Common Stock entitling them (for a period expiring within forty-five (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 (or having a conversion price per share, if a security convertible into Common Stock) less than the then current per share Fair Market Value of the Common Stock on such record date, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be 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 Fair Market Value and the denominator of which 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).  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, whose determination shall be described in a statement filed with the Rights Agent.  The Rights Agent may be conclusively assumed to have no knowledge of any such determination until it receives such statement and may conclusively rely on such statement.  Shares of Common Stock owned by or held for the account of the Corporation 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 and in the event that such rights, options or warrants are not so issued, the Exercise Price shall be adjusted to be the Exercise Price which would then be in effect if such record date had not been fixed.

(d)           In case the Corporation shall fix a record date for the making of a distribution to all holders of the Common Stock (including any such distribution made in connection with a consolidation or merger in which the Corporation is the continuing or surviving corporation) of evidences of indebtedness of the Corporation or any of its Subsidiaries, cash (other than a regular quarterly cash dividend not in excess of one hundred fifty percent (150%) of the previous regular quarterly cash dividend), other assets (other than a dividend payable in shares of Common Stock) or options, rights or warrants to subscribe for shares of the Corporation or any Subsidiary (excluding those referred to in Section 11(c) hereof), the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the Fair Market Value of the shares of Common Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and the Rights Agent may be

20

conclusively assumed to have no knowledge of any such determination until it receives such statement and may conclusively rely on such statement) of the portion of the assets or evidences of indebtedness or options, rights or warrants so to be distributed in respect of one share of Common Stock, and the denominator of which shall be such current Fair Market Value of the shares of Common Stock.  Such adjustment shall be made successively whenever such a record date is fixed, and, in the event that such distribution is not so made notwithstanding the setting of a record date therefor, the Exercise Price shall again be adjusted to be the Exercise Price which would then be in effect if such record date had not been fixed.

(e)           Unless the Corporation shall have exercised its election as provided in Section 11(f), upon each adjustment of the Exercise Price as a result of the calculations made in Section 11(c) or (d), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of one one-thousandths (1/1000) of a share of Preferred Stock obtained by (i) multiplying (A) the number of one one-thousandths (1/1000) of a share of Preferred Stock that could be purchased upon exercise of a Right immediately prior to the adjustment pursuant to this Section 11(e) by (B) the Exercise Price in effect immediately prior to such adjustment of the Exercise Price and (ii) dividing the product so obtained by the Exercise Price in effect immediately after such adjustment of the Exercise Price.

(f)            The Corporation may elect, on or after the date of any adjustment of the Exercise Price pursuant to Section 11(c) or 11(d), to adjust the number of Rights in substitution for any adjustment pursuant to Section 11(e) in the number of one one-thousandths (1/1000) of a share of Preferred 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 one one-thousandths (1/1000) of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment.  Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights obtained by dividing the Exercise Price in effect immediately prior to adjustment of the Exercise Price by the Exercise Price in effect immediately after adjustment of the Exercise Price.  The Corporation shall make a public announcement (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such adjustment has occurred) 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 Exercise 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 the Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(f), the Corporation 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 14 hereof, the additional Rights, if any, to which such holders shall be entitled as a result of such adjustment, or, at the option of the Corporation, shall cause to be distributed to

21

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 Corporation, 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 shall be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

(g)           All calculations under this Section 11 shall be made to the nearest cent or to the nearest one one-thousandth (1/1000) of a share, as the case may be.

(h)           Irrespective of any adjustment or change in the Exercise Price or the number of shares of Preferred Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Exercise Price and the number of shares to be issued upon exercise of the Rights as in the initial Right Certificates issued hereunder but, nevertheless, shall represent the Rights as so adjusted.

(i)            Before taking any action that would cause an adjustment reducing the purchase price per whole share of Preferred Stock upon exercise of the Rights below the then par value, if any, of the shares of Preferred Stock, the Corporation shall use its reasonable best efforts to take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of such Preferred Stock at such adjusted purchase price per share.

(j)            Anything in this Section 11 to the contrary notwithstanding, in the event of any reclassification of stock of the Corporation or any recapitalization, reorganization or partial liquidation of the Corporation or similar transaction, the Corporation shall be entitled to make such further adjustments in the number of shares of Preferred Stock which may be acquired upon exercise of the Rights, and such adjustments in the Exercise Price therefor, in addition to those adjustments expressly required by the other paragraphs of this Section 11, as the Board of Directors shall determine to be necessary or appropriate in order for the holders of the Rights in such event to be treated equitably and in accordance with the purpose and intent of this Agreement or in order that any such event shall not, but for such adjustment, in the opinion of counsel to the Corporation, result in the stockholders of the Corporation being subject to any United States federal income tax liability by reason thereof.  The Rights Agent may conclusively assume that no such determinations have been made until it receives a written statement from the Corporation to such effect and may conclusively rely on such statement.

(k)           If as a result of an adjustment made pursuant to Section 11(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Corporation other than the Preferred Stock, thereafter the Exercise Price and the number of such other shares so receivable upon exercise of a 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 Stock contained in Sections 11(a), 11(c), 11(d), 11(e), 11(f) and 11(j) hereof, as applicable, and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares.

Section 12.             Certification of Adjusted Exercise Price or Number of Shares.  Whenever an adjustment is made as provided in Section 11, 13, 23(c) or 27 hereof, the Corporation shall (a) promptly prepare a certificate duly executed by an officer of the Corporation setting forth such adjustment, and a brief statement of the facts giving rise to such adjustment, (b) promptly file with the Rights Agent and with each transfer agent for the Preferred Stock a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate in accordance with Section 25.  Notwithstanding the foregoing, the failure of the Corporation to make such certification or give such notice shall not affect the validity of or the force or effect of the requirement for such adjustment.  Any adjustment to be made pursuant to Section 11, 13, 23(c) or 27 hereof shall be effective as of the date of the event giving rise to such adjustment.  The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment, or statement, therein contained, and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of any adjustment unless and until it shall have received such certificate.

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

(a)           In the event that, at any time after the time that any Person becomes an Acquiring Person, (i) the Corporation shall, directly or indirectly, consolidate with, or merge with and into, any other Person or Persons and the Corporation shall not be the surviving or continuing corporation of such consolidation or merger, (ii) any Person or Persons shall, directly or indirectly, consolidate with, or merge with and into, the Corporation, and the Corporation shall be the continuing or surviving corporation of such consolidation or merger and, in connection with such consolidation or merger, all or part of the outstanding shares of Common Stock shall be changed or converted into or exchanged for stock or other securities of any other Person or of the Corporation or cash or any other property or (iii) the Corporation or one or more of its Subsidiaries shall, directly or indirectly, sell or otherwise transfer to any other Person in one or more transactions, assets or earning power aggregating more than fifty percent (50%) of the assets or earning power of the Corporation and its Subsidiaries (taken as a whole), then, on the first occurrence of any such event, proper provision shall be made so that (A) each holder of record of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive, upon the exercise thereof at a price equal to the then current Exercise Price multiplied by the number of one one-thousandths (1/1000) of a share of Preferred Stock for which a Right is then exercisable, in accordance with the terms of this Agreement and in lieu of shares of Preferred Stock, such number of shares of validly issued, fully paid, non-assessable and freely tradeable Common Stock of the Principal Party (as such term is hereinafter defined), not subject to any liens, encumbrances, rights

23

of first refusal or other adverse claims, as shall equal the result obtained by (1) multiplying the then current Exercise Price by the number of one one-thousandths (1/1000) of a share of Preferred Stock for which a Right is then exercisable and dividing that product by (2) fifty percent (50%) of the then per share Fair Market Value of the Common Stock of the Principal Party on the date of the consummation of such consolidation, merger, sale or transfer; provided, however, that the Exercise Price (as adjusted) and the number of shares of Common Stock of such Principal Party so receivable upon exercise of a Right shall be subject to further adjustment as appropriate in accordance with Section 11 hereof to reflect any events occurring in respect of the Common Stock of such Principal Party after the occurrence 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 Corporation pursuant to this Agreement, (C) the term “Corporation” for all purposes of this Agreement shall thereafter be deemed to refer to such Principal Party, (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 the provisions of Section 9 hereof applicable to the reservation of Preferred Stock) 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 its shares of Common Stock thereafter deliverable upon the exercise of the Rights; provided, however, that, upon the subsequent occurrence of any merger, consolidation, sale of all or substantially all of the assets, recapitalization, reclassification of shares, reorganization or other extraordinary transaction in respect of such Principal Party, each holder of a Right shall thereupon be entitled to receive, upon exercise of a Right and payment of the Exercise Price, such cash, shares, rights, warrants and other property which such holder would have been entitled to receive had it, at the time of such transaction, owned the shares of Common Stock of the Principal Party purchasable upon the exercise of a Right, and such Principal Party shall take such steps (including, but not limited to, reservation of shares of stock) as may be necessary to permit the subsequent exercise of the Rights in accordance with the terms hereof for such cash, shares, rights, warrants and other property and (E) the provisions of Section 11(a)(ii) hereof shall be of no effect following the occurrence of any event described in clause (i), (ii) or (iii) above of this Section 13(a).

(b)           “Principal Party” shall mean:

(i)            in the case of any transaction described in clause (i) or (ii) of the first sentence of Section 13(a) hereof (A) the Person that is the issuer of the securities into which shares of Common Stock of the Corporation are changed or otherwise exchanged or converted in such merger or consolidation, or, if there is more than one such issuer, the issuer of the Common Stock of which has the greatest market value or (B) if no securities are so issued, (1) the Person that is the other party to the merger or consolidation and that survives such merger or consolidation, or, if there is more than one such Person, the Person the Common Stock of which has the greatest market value or (2) if the Person that is the other party to the merger or consolidation

24

does not survive the merger or consolidation, the Person that does survive the merger or consolidation (including the Corporation if it survives); and

(ii)           in the case of any transaction described in clause (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, or, if each Person that is a party to such transaction or transactions receives the same portion of the assets or earning power so transferred or if the Person receiving the greatest portion of the assets or earning power cannot be determined, whichever of such Persons as is the issuer of Common Stock having the greatest market value of shares outstanding;

provided, however, that in any such case, if the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, then (A) if such Person is a direct or indirect Subsidiary of another Person the Common Stock of which is and has been so registered, the term “Principal Party” shall refer to such other Person, (B) if such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stock of all of which are and have been so registered, the term “Principal Party” shall refer to whichever of such Persons is the issuer of the Common Stock having the greatest market value of shares outstanding, or (C) if such Person is owned, directly or indirectly, by a joint venture formed by two or more Persons that are not owned, directly or indirectly, by the same Person, the rules set forth in clauses (A) and (B) above shall apply to each of the owners having an interest in the venture as if the Person owned by the joint venture was a Subsidiary of both or all of such joint venturers, and the Principal Party in each such case shall bear the obligations set forth in this Section 13 in the same ratio as its interest in such Person bears to the total of such interests.

(c)           The Corporation shall not consummate any consolidation, merger or sale or transfer of assets or earning power referred to in Section 13(a) unless the Principal Party shall have a sufficient number of authorized shares of its Common Stock that have not been issued or reserved for issuance to permit exercise in full of all Rights in accordance with this Section 13 and unless prior thereto the Corporation and the Principal Party involved therein shall have executed and delivered to the Rights Agent an agreement confirming that the Principal Party shall, upon consummation of such consolidation, merger or sale or transfer of assets or earning power, assume this Agreement in accordance with Section 13(a) hereof and that all rights of first refusal or preemptive rights in respect of the issuance of shares of Common Stock of the Principal Party upon exercise of outstanding Rights have been waived and that such transaction shall not result in a default by the Principal Party under this Agreement, and further providing that, as soon as practicable after the date of any consolidation, merger or sale or transfer of assets or earning power referred to in Section 13(a) hereof, the Principal Party will:

(i)            prepare and file a registration statement under the Securities Act with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, use its reasonable best efforts to cause such

25

registration statement to become effective as soon as practicable after such filing and use its best efforts to cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the date of expiration of the Rights, and similarly comply with applicable state securities laws;

(ii)           use its reasonable best efforts to list (or continue the listing of) the Rights and the securities purchasable upon exercise of the Rights on a national securities exchange in the United States;

(iii)          deliver to holders of the Rights historical financial statements for the Principal Party which comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act.  In the event that any of the transactions described in Section 13(a) hereof shall occur at any time after the occurrence of a transaction described in Section 11(a)(ii) hereof, the Rights which have not theretofore been exercised shall, subject to the provisions of Section 7(e) hereof, thereafter be exercisable in the manner described in Section 13(a); and

(iv)          obtain waivers of any rights of first refusal or preemptive rights in respect of the Common Stock of the Principal Party subject to purchase upon exercise of outstanding Rights.

(d)           In case the Principal Party which is to be a party to a transaction referred to in this Section 13 has a provision in any of its authorized securities or in its Certificate of Incorporation or Bylaws or other instrument governing its affairs, which provision would have the effect of (i) causing such Principal Party to issue, in connection with, or as a consequence of, the consummation of a transaction referred to in this Section 13, shares of Common Stock of such Principal Party at less than the then Fair Market Value per share (determined pursuant to Section 11(b) hereof) or securities exercisable for, or convertible into, Common Stock of such Principal Party at less than such then Fair Market Value (other than to holders of Rights pursuant to this Section 13) or (ii) providing for any special tax or similar payment in connection with the issuance to any holder of a Right of Common Stock of such Principal Party pursuant to the provisions of this Section 13, then, in such event, the Corporation shall not consummate any such transaction unless prior thereto the Corporation and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing that the provision in question of such Principal Party shall have been canceled, waived or amended, or that the authorized securities shall be redeemed, so that the applicable provision will have no effect in connection with, or as a consequence of, the consummation of the proposed transaction.

(e)           The Corporation covenants and agrees that it shall not, at any time after any Person becomes an Acquiring Person, enter into any transaction of the type described in clauses (i) through (iii) of the first sentence of Section 13(a) hereof if (i) at the time of or immediately after such consolidation, merger, sale, transfer or other transaction there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the

26

benefits intended to be afforded by the Rights, (ii) prior to, simultaneously with or immediately after such consolidation, merger, sale, transfer or other transaction, the stockholders of the Person who constitutes, or would constitute, the Principal Party for purposes of Section 13(a) hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates or Associates or (iii) the form or nature of organization of the Principal Party would preclude or limit the exercisability of the Rights.

Section 14.             Fractional Rights and Fractional Shares.

(a)           The Corporation shall not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights (i.e., Rights to acquire less than one one-thousandth (1/1000) of a share of Preferred Stock), unless such fractional Rights result from a transaction referred to in Section 11(a)(i) or 11(f) hereof.  If the Corporation shall determine not to issue such fractional Rights, then, in lieu of such fractional Rights, there shall be paid to the holders of record 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 Fair Market Value of a whole Right.

(b)           The Corporation shall not be required to issue fractions of shares of Preferred Stock (other than fractions that are integral multiples of one one-thousandth (1/1000) of a share) upon exercise of the Rights or to distribute certificates which evidence fractional shares (other than fractions that are integral multiples of one one-thousandth (1/1000) of a share).  In lieu of issuing fractions of shares of Preferred Stock, the Corporation may, at its election, issue depositary receipts evidencing fractions of shares pursuant to an appropriate agreement between the Corporation and a depositary selected by it, provided that such agreement shall provide that the holders of such depositary receipts shall have all of the rights, privileges and preferences to which they would be entitled as owners of the Preferred Stock.  With respect to fractional shares that are not integral multiples of one one-thousandth (1/1000) of a share, if the Corporation does not issue such fractional shares or depositary receipts in lieu thereof, there shall be paid to the holders of record 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 Fair Market Value of a share of Preferred Stock.  As soon as practicable, the Corporation shall notify the Rights Agent of any election pursuant to this Section 14(b).  The Rights Agent may assume conclusively that no such election has occurred until it receives such notice.

(c)           The holder of a Right by the acceptance of a Right expressly waives his right to receive any fractional Right or any fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-thousandth (1/1000) of a share) upon exercise of a Right.

(d)           Whenever a payment for fractional Rights or fractional shares is to be made by the Rights Agent, the Corporation shall (i) promptly prepare and deliver to the Rights Agent a certificate setting forth in reasonable detail the facts related to such payments, and (ii) provide sufficient monies to the Rights Agent in the form of fully

27

collected funds to make such payments.  The Rights Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be deemed to have knowledge of any payment for fractional Rights or fractional shares under any Section of this Agreement relating to the payment of fractional Rights or fractional shares unless and until the Rights Agent shall have received such a certificate and sufficient monies.

Section 15.             Rights of Action.  All rights of action in respect of this Agreement, except the rights of action given to the Rights Agent in Section 18 and Section 20 hereof, are vested in the respective registered holders of the Right Certificates (and, prior to the Distribution Date, the holders of record of the Common Stock), and any holder of record 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, on his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Corporation 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.  Notwithstanding anything in this Agreement to the contrary, neither the Corporation nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, judgment, decree or ruling (whether interlocatory or final) issued by a court of competent jurisdiction or by a governmental, regulatory, self regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; provided, however, that the Corporation shall use its reasonable best efforts to have any such injunction, order, judgment, decree or ruling lifted or otherwise overturned as soon as possible.

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

(a)           prior to the Distribution Date, the Rights shall be evidenced by the certificates for Common Stock (or in the case of uncertificated shares of Common Stock, by the book-entry account that evidences record ownership of such shares) registered in the name of the holders of Common Stock (together, as applicable, with the Summary of Rights), which certificates for Common Stock (or book-entry account) shall also constitute certificates for Rights, and not by separate Right Certificates, and each Right shall be transferable only simultaneously and together with the transfer of shares of Common Stock;

28

(b)           after the Distribution Date, the Right Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer along with a form of assignment and certificate set forth on the reverse side thereof duly executed, accompanied by a signature guarantee and such other and further documentation as the Rights Agent may require; and

(c)           the Corporation and the Rights Agent may deem and treat the Person in whose name the Right Certificate (or, prior to the Distribution Date, the associated Common Stock certificate or, in the case of uncertificated shares of Common Stock, the book-entry account evidencing record ownership of such shares) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificates or the associated Common Stock certificate made by anyone other than the Corporation or the Rights Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent shall be affected by any notice to the contrary.

Section 17.             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 Preferred Stock or any other securities 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 or other securityholder of the Corporation or of a securityholder of any other Person 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 securityholder action, or to receive notice of meetings or other actions affecting stockholders or securityholders (except as provided in Section 24 hereof), or to receive dividends or subscription rights, or otherwise, except in any such case the rights, if any, in respect thereof provided by this Agreement, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof for such stock or other security.

Section 18.             Concerning the Rights Agent.

(a)           The Corporation 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 expenses and other disbursements incurred in the preparation, negotiations, delivery, amendments, administration and execution of this Agreement and the exercise and performance of its duties hereunder, including but not limited to any taxes or charges imposed as a result of the action taken by it hereunder.  The Corporation also agrees to indemnify the Rights Agent for, and to hold it harmless against, any and all loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the fees and expenses of legal counsel), incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent, (which gross negligence, bad faith or

29

willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered, or omitted to be taken by the Rights Agent in connection with the acceptance, administration, exercise and performance of its duties under this Agreement, including the costs and expenses (including attorneys’ fees and expenses) of defending against any claim of liability hereunder.  The costs and expenses incurred in enforcing this right of indemnification shall be paid by the Corporation.  The provisions of this Section 18 and Section 20 below shall survive the termination of this Agreement, the exercise or expiration of the Rights and the resignation, replacement or removal of the Rights Agent.

(b)           Subject to Section 20(c) hereof, the Rights Agent shall be authorized and protected against, and shall incur no liability for or in respect of, any action taken, suffered or omitted to be taken by it in connection with its acceptance and administration of this Agreement and the exercise and performance of its duties hereunder, in reliance upon any Right Certificate or certificate for Preferred Stock or for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, instruction, direction, consent, certificate, statement or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper person or persons, or otherwise upon the advice of counsel.  The Rights Agent shall not be deemed to have any knowledge of any event of which it was supposed to receive notice thereof hereunder, and the Rights Agent shall be fully protected and shall incur no liability for failing to take any action in connection therewith unless and until it has received such notice in writing.

Section 19.             Merger, Consolidation or Change of Name of the Rights Agent.

(a)           Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the shareholder services or stock transfer business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof.  In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of 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.

30

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

(a)           The Rights Agent may consult with legal counsel of its selection (who may be an employee of or outside legal counsel for the Corporation or the Rights Agent or otherwise), and the advice or opinion of such counsel shall be full and complete authorization and protection to the Rights Agent, and the Rights Agent shall incur no liability for, or in respect of any action taken, suffered or to be taken omitted by it in accordance with such advice or opinion.

(b)           Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Corporation prior to taking, suffering any or omitting to take 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 a person reasonably believed by the Rights Agent to be the Chairman of the Board, the President or any Vice President and by the Treasurer or any Assistant Treasurer or the Secretary or any Assistant Secretary of the Corporation and delivered to the Rights Agent.  Any such certificate shall be full and complete authorization and protection to the Rights Agent for any action taken, suffered or omitted to be taken by it under the provisions of this Agreement in reliance upon such certificate.

(c)           The Rights Agent shall be liable hereunder to the Corporation and any other Person only for its own gross negligence, bad faith, or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction).  Anything to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential, or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage.  Any liability of the Rights Agent under this Agreement shall be limited to the amount of annual fees paid by the Corporation to the Rights Agent.

(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

31

(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 Corporation only.

(e)           The Rights Agent shall (i) not have any liability for, or be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof), (ii) nor shall it have any liability for or be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Right Certificate, (iii) nor shall it have any liability for or be responsible for any adjustment or change in the exercisability of Rights 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 change, adjustment or procedure (except with respect to the exercise of Rights evidenced by Right Certificates after receipt by the Rights Agent of a certificate delivered pursuant to Section 12 hereof describing any such adjustment) and (iv) not by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Preferred Stock or other security to be delivered pursuant to the exercise of any Right or as to whether any shares of Preferred Stock or other security will, when issued, be validly authorized and issued, fully paid and nonassessable.

(f)            The Corporation 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 the Agreement.

(g)           The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder and to accept and rely on any certificates delivered pursuant to any provision hereof from any person reasonably believed by the Rights Agent to be the Chairman of the Board, the President or any Vice President or the Secretary or the Treasurer of the Corporation, and is authorized to apply to such officers for advice or instructions in connection with its duties, and such instructions shall be full authorization and protection to the Rights Agent, and the Rights Agent and it shall not be liable for or in respect of any action taken, suffered or omitted to be taken to be taken by it in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions.  The Rights Agent shall be fully authorized and protected in relying upon the most recent instructions received by it from any such officer.  Any application by the Rights Agent for written instructions from the Corporation may, at the option of the Rights Agent, set forth in writing any action proposed to be taken, suffered or omitted to be taken by the Rights Agent under this Agreement and the date on and/or after which such action shall be taken or such omission shall be effective.  The Rights Agent shall not be liable for any action taken, suffered or omitted to be taken by the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer of the Corporation actually

32

receives such application unless any such officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instructions from the Corporation in response to such application specifying the action to be taken, suffered or omitted to be taken, or a written objection by the Corporation to such proposal.

(h)           The Rights Agent and any stockholder, director, officer, Affiliate or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Corporation or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as though it were not the Rights Agent under this Agreement.  Nothing herein shall preclude the Rights Agent, or any such shareholder, director, officer, Affiliate or employee from acting in any other capacity for the Corporation 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 (through its directors, officers and employees) or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation or any other Person resulting from any such act, default, neglect or misconduct, absent gross negligence or willful misconduct (which gross negligence or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction) 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 contained in the form of assignment or the form of election to purchase set forth on the reverse thereof, as the case may be, has not been properly completed to certify the holder is not an Acquiring Person (or an Affiliate or Associate thereof) or not duly executed, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Corporation.

Section 21.             Change of Rights Agent.  The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days’ notice in writing mailed to the Corporation and to each transfer agent of the Common Stock known to the Rights Agent and the Preferred Stock by registered or certified mail.  The Corporation may remove the Rights Agent or any successor Rights Agent upon thirty (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 and the Preferred Stock by registered or certified mail.  If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Corporation shall appoint a successor to the Rights Agent.  If the Corporation shall fail to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall,

with such notice, submit his Right Certificate for inspection by the Corporation), then the Corporation shall become the Rights Agent or the holder of record 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 Corporation or by such a court, shall be (a) a Person organized and doing business under the laws of the United States or of any state thereof, which is authorized under such laws to exercise stock transfer powers or conduct a shareholder services business and is subject to supervision or examination in the conduct of its stock transfer business by federal or state authorities and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000 or (b) an Affiliate controlled by or under common control with one or more Persons described in clause (a) of this sentence.  After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed, but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose.  Not later than the effective date of any such appointment, the Corporation shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock and Preferred 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 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.  Notwithstanding the foregoing provisions, in the event of resignation, removal or incapacity of the Rights Agent, the Corporation shall have the authority to act as the Rights Agent until a successor Rights Agent shall have assumed the duties of the Rights Agent hereunder.

Section 22.             Issuance of New Right Certificates.  Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Corporation may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the Exercise 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.  In addition, in connection with the issuance or sale of Voting Stock following the Distribution Date and prior to the Expiration Date, the Corporation may, with respect to Voting Stock so issued or sold pursuant to (a) the exercise of stock options, (b) under any employee plan or arrangement, (c) upon the exercise, conversion or exchange of securities, notes or debentures issued by the Corporation or (d) a contractual obligation of the Corporation, in each case existing prior to the Distribution Date, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale.

Section 23.             Redemption.

(a)           The Board of Directors may, at its option, at any time prior to such time as any Person becomes an Acquiring Person, redeem all, but not less than all, of the

34

then outstanding Rights at a redemption price of $0.01 per Right, subject to adjustment as provided in Section 23(c) hereof (the “Redemption Price”).  The redemption of the Rights by the Board of Directors may be made effective at such time after the Board of Directors’ action to redeem the Rights on such basis and subject to such conditions, as the Board of Directors, in its sole and absolute discretion, may establish. Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable prior to the expiration of the Corporation’s right of redemption.

(b)           Without any further action and without any notice, the right to exercise the Rights will terminate effective at the time so designated by action of the Board of Directors ordering the redemption of the Rights and the only right thereafter of the holders of Rights shall be to receive the Redemption Price.  Within ten (10) days after the effective time of the action of the Board of Directors ordering the redemption of the Rights, the Corporation shall give notice (with prompt written notice thereof to the Rights Agent; and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such redemption has occurred) 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; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption.  Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice.  Each notice of redemption will state the method by which the payment of the Redemption Price will be made.  At the option of the Board of Directors, the Redemption Price may be paid in cash to each Rights holder or by the issuance of shares (and, at the Corporation’s election pursuant to Section 14(b) hereof, cash or depositary receipts in lieu of fractions of shares other than fractions which are integral multiples of one one-thousandth (1/1000) of a share) of Preferred Stock or Common Stock having a Fair Market Value equal to such cash payment.

(c)           In the event the Corporation shall at any time after the date of this Agreement, but before such time as any Person becomes an Acquiring Person, (i) pay any dividend on Common Stock in shares of Common Stock, (ii) subdivide or split the outstanding shares of Common Stock into a greater number of shares or (iii) combine or consolidate the outstanding shares of Common Stock into a smaller number of shares or effect a reverse split of the outstanding shares of Common Stock and as a consequence thereof the number of Rights outstanding shall change, then, and in each such event, the Redemption Price may, by action of the Board of Directors in its discretion, be appropriately adjusted in respect of such transaction so as to maintain the aggregate Redemption Price of all Rights after such transaction at the same amount, insofar as practicable, as before the transaction.

Section 24.             Notice of Proposed Actions.

(a)           In case the Corporation, after the Distribution Date, shall propose (i) to effect any of the transactions referred to in Section 11(a)(i) hereof or to pay any

35

dividend to the holders of record of its shares of Common Stock payable in shares of capital stock of any class or to make any other distribution to the holders of record of its Common Stock (other than a regular periodic cash dividend at a rate not in excess of one hundred fifty percent (150%) of the rate of the last cash dividend theretofore paid), (ii) to offer to the holders of record of its Common Stock options, warrants, or other rights to subscribe for or to purchase shares of Common Stock (including any security convertible into or exchangeable for Common Stock) or shares of stock of any class or any other securities, options, warrants, convertible or exchangeable securities or other rights, (iii) to effect any reclassification of its Preferred Stock or Common Stock or any recapitalization or reorganization of the Corporation, (iv) to effect any consolidation or merger with or into, or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one or more transactions, of more than fifty percent (50%) of the assets or earning power of the Corporation and its Subsidiaries (taken as a whole) to, any other Person or Persons, or (v) to effect the liquidation, dissolution or winding up of the Corporation, then, in each such case, the Corporation shall give to each holder of record of a Right Certificate, in accordance with Section 25 hereof, notice of such proposed action, which shall specify the record date for the purposes of such transaction referred to in Section 11(a)(i) or such dividend or distribution, or the date on which such reclassification, recapitalization, reorganization, consolidation, merger, sale or transfer of assets, liquidation, dissolution, or winding up is to take place and the record date for determining participation therein by the holders of record of Common Stock or Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least ten (10) days prior to the record date for determining holders of record of the Preferred Stock for purposes of such action, and in the case of any such other action, at least ten (10) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of record of Common Stock or Preferred Stock, whichever shall be the earlier.  The failure to give notice required by this Section 24 or any defect therein shall not affect the legality or validity of the action taken by the Corporation or the vote upon any such action.

(b)           In case the event referred to in Section 11(a)(ii) hereof shall occur, then the Corporation shall as soon as practicable thereafter, in accordance with Section 25 hereof, give to each holder of a Right notice of the occurrence of such event, which notice shall describe the event and the consequences of the event to holders of Rights under Section 11(a)(ii) hereof.

Section 25.             Notices.  Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of record of any Right Certificate or Right to or on the Corporation shall be in writing and shall be considered given upon receipt or seven (7) Business Days after being sent by first-class mail, postage prepaid, in any case addressed (until another address is filed in writing with the Rights Agent) or by facsimile as follows:

Notices or demands authorized by this Agreement to be given or made by the Corporation or the Rights Agent to the holder of any Right Certificate shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed to such holder at the address of such holder as shown on the registry books of the Corporation.

Section 26.             Supplements and Amendments.  For as long as the Rights are then redeemable, the Corporation (at the direction of the Board of Directors in its sole and absolute discretion) may, and the Rights Agent shall if the Corporation so directs, supplement or amend any provision of this Agreement in any manner without the approval of any holders of the Rights.  At any time when the Rights are not then redeemable, the Corporation (at the direction of the Board of Directors) may, and the Rights Agent shall if the Corporation so directs, supplement or amend this Agreement without the approval of any holders of Rights (a) in order to cure any ambiguity, (b) to correct or supplement any provision contained herein that may be inconsistent with any other provisions herein or otherwise defective, including without limitation, any change in order to satisfy any applicable law, rule or regulation, (c) shorten or lengthen any time period herein, or (d) in any way that will not materially adversely affect the interests of the holders of Rights as such (other than an Acquiring Person or any other Person in whose hands Rights are null and void under the provisions of Section 7(e) hereof).  Notwithstanding anything contained in this Agreement to the contrary, no supplement or amendment shall (A) be made which changes the Redemption Price, (B) cause this Agreement again to become amendable other than in accordance with this sentence or (C) cause the Rights again to become redeemable.  Upon the delivery of a certificate from an

37

appropriate officer of the Corporation which states that the proposed supplement or amendment is in compliance with the terms of this Section 26, the Rights Agent shall execute such supplement or amendment, subject to the last sentence hereof.  Any and all supplements and amendments to this Agreement shall be evidenced in writing signed by the Corporation and the Rights Agent.  Notwithstanding anything contained in this Agreement to the contrary, the Rights Agent may, but shall not be obligated to, enter into any supplement or amendment that affects the Rights Agent’s own rights, liabilities, duties, obligations or immunities under this Agreement.

Section 27.             Exchange.

(a)           The Board of Directors may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 7(e) hereof) by exchanging for each such Right one share of Common Stock of the Corporation, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such number of shares of Common Stock per Right being hereinafter referred to as the “Exchange Ratio”).  The Rights Agent shall be given written notice as soon as practicable of any such exchange and the Exchange Ratio pursuant to which such exchange is effected and shall be deemed to have no knowledge thereof until it receives such notice.  The exchange of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish.  Prior to effecting an exchange pursuant to this Section 27, the Board of Directors may direct the Corporation to enter into a Trust Agreement in such form and with such terms as the Board of Directors shall then approve (the “Trust Agreement”).  If the Board of Directors so directs, the Corporation shall enter into the Trust Agreement and shall issue to the trust created by such agreement (the “Trust”) all of the shares of Common Stock issuable pursuant to the exchange, and all Persons entitled to receive shares pursuant to the exchange shall be entitled to receive such shares (and any dividends or distributions made thereon after the date on which such shares are deposited in the Trust) only from the Trust and solely upon compliance with the relevant terms and provisions of the Trust Agreement.  Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than an Exempt Person), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of fifty percent (50%) or more of the Voting Stock then outstanding.  From and after the occurrence of an event specified in Section 13(a) hereof, any Rights that theretofore have not been exchanged pursuant to this Section 27(a) shall thereafter be exercisable only in accordance with Section 13 and may not be exchanged pursuant to this Section 27(a).

(b)           Immediately upon the action of the Board of Directors ordering the exchange of any Rights pursuant to Section 27(a) 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

38

Ratio.  The Corporation shall promptly give public notice of any such exchange, and the Rights Agent shall be given prompt written notice of any such exchange (and until such written notice is received by the Rights Agent, the Rights Agent may assume conclusively that no such exchange has occurred); provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange.  The Corporation 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 null and void pursuant to the provisions of Section 7(e) 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 27, the Corporation shall substitute to the extent of such insufficiency, for each share of Common Stock that would otherwise be issuable upon exchange of a Right, a number of shares of Preferred Stock or fractions thereof having an aggregate Fair Market Value equal to the Fair Market Value of one share of Common Stock as of the date any Person becomes an Acquiring Person.

(d)           The Corporation shall not be required to issue fractions of shares of Common Stock or to distribute certificates which evidence fractional shares.  In lieu of such fractional shares, the Corporation shall pay to the registered holders of the Right Certificates with regard to which such fractional shares of Common Stock would otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole share of Common Stock.  For the purposes of this Section 27(d), the current market value of a whole share of Common Stock shall be the closing price of a share of Common Stock for the Trading Day immediately prior to the date of exchange pursuant to this Section 27.

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

Section 29.             Benefits of this Agreement.  This Agreement shall be for the sole and exclusive benefit of the Corporation, the Rights Agent and the holders of record of the Right Certificates (and, prior to the Distribution Date, the holders of Common Stock in their capacity as holders of the Rights).  Nothing in this Agreement shall be construed to give to any Person other than the Corporation, the Rights Agent and the registered holders of the Right Certificates (and, prior to the Distribution Date, the holders of Common Stock in their capacity as holders of the Rights) any legal or equitable right, remedy or claim under this Agreement.

39

Section 30.             Governing Law.  This Agreement and each Right Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed and enforced in accordance with the laws of such state applicable to contracts to be made and performed entirely within such state.

Section 31.             Counterparts.  This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

Section 32.             Descriptive Headings.  Descriptive headings of the several Sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

Section 33.             Severability.  If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

Section 34.             Determinations and Actions by the Board of Directors.  The Board of Directors shall have the exclusive power and authority to administer, interpret and apply this Agreement and to exercise the rights and powers specifically granted to the Board of Directors or to the Corporation by this Agreement or by law and may take such action as may be necessary or advisable in the administration of this Agreement or to amend or supplement this Agreement in accordance with its terms, including, without limitation, the right and power (a) to make all determinations deemed necessary or advisable for the administration of this Agreement, (b) to decide to redeem the Rights and (c) to decide to amend or supplement this Agreement.  All such actions, calculations, interpretations and determinations (including any decision not to take any action) done or made by the Board of Directors in good faith shall (i) be final, conclusive and binding on the Corporation, the Rights Agent, the holders of the Rights, as such, and all other Persons and (ii) not subject any member of the Board of Directors to any liability to the holders of Rights.  Notwithstanding anything contained herein to the contrary, for all purposes of this Agreement, the Rights Agent is entitled always to assume that the Board of Directors acted in good faith and shall be fully protected and incur no liability in reliance thereon.

Section 35.             Force Majeure.  Notwithstanding anything to the contrary contained herein, the Rights Agent shall not incur any liability for not performing, or a delay in the performance of, any act, duty, obligation or responsibility by reason of any occurrence beyond the reasonable control of the Rights Agent (including, without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunctions or computer facilities, or loss of data due to power failures

40

or mechanical difficulties with information storage or retrieval systems, labor difficulties, war or civil unrest).

Section 36.             Miscellaneous.

(a)           The Corporation acknowledges that the Rights Agent is subject to the customer identification program (“Customer Identification Program”) requirements under the USA PATRIOT Act and its implementing regulations, and that the Rights Agent must obtain, verify and record information that allows the Rights Agent to identify the Corporation.  Accordingly, prior to accepting an appointment hereunder, the Rights Agent may request information from the Corporation that will help the Rights Agent to identify the Corporation, including without limitation the Corporation’s physical address, tax identification number, organizational documents, certificate of good standing, license to do business, or any other information that the Rights Agent deems necessary.  The Corporation agrees that the Rights Agent cannot accept an appointment hereunder unless and until the Rights Agent verifies the Corporation’s identity in accordance with the Customer Identification Program requirements.

(b)           The Bank of New York Mellon Corporation (“BNYM”) has adopted an incentive compensation program designed (i) to facilitate clients gaining access to and being provided with explanations about the full range of products and services offered by BNYM and its subsidiaries and (ii) to expand and develop client relationships.  This program may lead to the payment of referral fees and/or bonuses to employees of BNYM or its subsidiaries who may have been involved in a referral that resulted in the Corporation obtaining products or services from BNYM pursuant to this Agreement or which may be ancillary or supplemental to such products or services.  Any such referral fees or bonuses are funded solely out of fees and commissions payable by the Corporation under this Agreement or with respect to such ancillary or supplemental products or services.  Under no circumstances will the payment of such fees and/or bonuses contemplated under this Section 36(b) increase the amount payable by the Corporation under any other provision of this Agreement.

Exhibit A

CERTIFICATE OF DESIGNATIONS

OF

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

OF

IRON MOUNTAIN INCORPORATED

The undersigned duly authorized officer of Iron Mountain Incorporated, a Delaware corporation (the “Corporation”), in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware, hereby certifies that, pursuant to the authority conferred upon the board of directors of the Corporation (the “Board of Directors”) by the Certificate of Incorporation of the Corporation, the Board of Directors on March 23, 2011 adopted a resolution which creates a series of preferred stock of the Corporation designated as Series A Junior Participating Preferred Stock (the “Preferred Stock”) as follows:

RESOLVED, that pursuant to Section 151(g) of the General Corporation Law of the State of Delaware and the authority vested in the Board of Directors of the Corporation in accordance with the provisions of the Certificate of Incorporation of the Corporation, a series of preferred stock of the Corporation be, and hereby is, created and the powers, designations, preferences and relative, participating, optional or other special rights of the shares of such series, and the qualifications, limitations or restrictions thereof, be, and hereby are, as follows:

Section 1.               Designation and Amount.  The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” (the “Series A Preferred Stock”), par value $0.01 per share, and the number of shares constituting such series shall be 1,000,000.

Section 2.               Dividends and Distributions.

(a)           Subject to the rights of the holders of any shares of any series of preferred stock of the Corporation ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock shall be entitled to receive, when, as and if declared by the board of directors of the Corporation (the “Board of Directors”) out of funds legally available for that purpose, quarterly dividends payable in cash on the fifteenth day of January, April, July and October of each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Stock, in an amount per share (except in the case of the first Quarterly Dividend Payment Date if the date of the first issuance of Series A Preferred Stock is a date other than a Quarterly Dividend Payment Date, in which case such payment shall be a prorated portion of such amount) (rounded to the nearest cent) equal to the greater of (i) $1.00 and (ii) subject to the provisions for adjustment hereinafter set forth, one thousand (1,000) times the aggregate per share amount of all cash dividends declared or paid on the common stock, $0.01 par value per share, of the Corporation (the “Common Stock”).  In the event the Corporation shall, at any time after the issuance of any share or fraction of a share of Series A Preferred Stock,

make any distribution on the shares of Common Stock, whether by way of a dividend or a reclassification of stock, a recapitalization, reorganization or partial liquidation of the Corporation or otherwise, which is payable in cash or any debt security, debt instrument, real or personal property or any other property (other than cash dividends subject to the immediately preceding sentence, a distribution of shares of Common Stock or other capital stock of the Corporation or a distribution of options, rights or warrants to acquire any such share, including any debt security convertible into or exchangeable for any such share, at a price less than the Fair Market Value (as hereinafter defined) of such share of Common Stock), then, and in each such event, the Corporation shall simultaneously pay on each then outstanding share of Series A Preferred Stock a distribution, in like kind, of one thousand (1,000) times such distribution paid on a share of Common Stock (subject to the provisions for adjustment hereinafter set forth).  The dividends and distributions on the Series A Preferred Stock to which holders thereof are entitled pursuant to the first sentence of this paragraph and pursuant to the second sentence of this paragraph are hereinafter referred to as “Dividends” and the multiple of such cash and non-cash dividends on the Common Stock applicable to the determination of the Dividends, which shall initially be one thousand (1,000) but shall be adjusted from time to time as hereinafter provided, is hereinafter referred to as the “Dividend Multiple.”  In the event the Corporation shall at any time after March 23, 2011 (the “Effective Date”) declare or pay any dividend or make any distribution on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then in each such case the Dividend Multiple thereafter applicable to the determination of the amount of Dividends which holders of shares of Series A Preferred Stock shall be entitled to receive shall be the Dividend Multiple applicable immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(b)   The Corporation shall declare each Dividend at the same time it declares any cash or non-cash dividend or distribution on the Common Stock in respect of which a Dividend is required to be paid; provided, however, that if no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date (or, with respect to the first Quarterly Dividend Payment Date, the period between the first issuance of any share or fraction of a share of Series A Preferred Stock and such first Quarterly Dividend Payment Date), a dividend of $1.00 per share on the Series A Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.  No cash or non-cash dividend or distribution on the Common Stock in respect of which a Dividend is required to be paid shall be paid or set aside for payment on the Common Stock unless a Dividend in respect of such dividend or distribution on the Common Stock shall be simultaneously paid or set aside for payment (as the case may be), on the Series A Preferred Stock.

(c)   Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Preferred Stock from the first Quarterly Dividend Payment Date

2

following the date of issuance of any shares of Series A Preferred Stock, unless the date of issue of such shares is on or before the record date for the first Quarterly Dividend Payment Date, in which case Dividends shall begin to accrue and be cumulative from the date of issue of such shares, or unless the date of issue is a date after the record date for the determination of holders of shares of Series A Preferred Stock entitled to receive Dividends and on or before such Quarterly Dividend Payment Date, in which case dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid dividends shall not bear interest.  Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding.  The Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of Dividend declared thereon, which record date shall not be more than sixty (60) days prior to the date fixed for the payment thereof.

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

(a)   Subject to the provisions for adjustment hereinafter set forth, each share of Series A Preferred Stock shall entitle the holder thereof to one thousand (1,000) votes on all matters submitted to a vote of the holders of Common Stock.  The number of votes which a holder of Series A Preferred Stock is entitled to cast, as the same may be adjusted from time to time as hereinafter provided, is hereinafter referred to as the “Vote Multiple.”  In the event the Corporation shall at any time after the Effective Date declare or pay any dividend on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then in each such case the Vote Multiple thereafter applicable to the determination of the number of votes per share to which holders of shares of Series A Preferred Stock shall be entitled after such event shall be the Vote Multiple immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(b)   Except as otherwise provided herein, in the By-laws of the Corporation or by law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock shall vote together as a single class on all matters submitted to a vote of stockholders of the Corporation.

(c)   In the event that the Dividends accrued on the Series A Preferred Stock for four (4) or more quarterly dividend periods, whether consecutive or not, shall not have been declared and paid or irrevocably set aside for payment, the holders of record of preferred stock of the Corporation of all series (including the Series A Preferred Stock), other than any series in respect of which such right is expressly withheld by the By-laws of the Corporation or the authorizing resolutions included in any certificate of designations therefor, shall have the right, at the next meeting of stockholders called for

3

the election of directors, to elect two (2) members to the Board of Directors, which directors shall be in addition to the number required prior to such event (and to the extent that this shall require an increase in the maximum number of directors, the Board of Directors shall by resolution increase that number accordingly), to serve until the next annual meeting and until their successors are elected and qualified or their earlier resignation, removal or incapacity.  The holders of shares of Series A Preferred Stock shall continue to have the right to elect directors as provided by the immediately preceding sentence until all accrued and unpaid Dividends upon the outstanding shares of Series A Preferred Stock shall have been paid (or set aside for payment) in full.  Such directors may be removed for cause and replaced by such stockholders, and casual vacancies in such directorships may be filled only by such stockholders (or by the remaining director elected by such stockholders, if there be one) in the manner permitted by law; provided, however, that any such action by stockholders shall be taken at a meeting of stockholders and shall not be taken by written consent thereto.

(d)   Except as otherwise required by the By-laws of the Corporation, by law or as set forth herein, holders of Series A Preferred Stock shall have no other special voting rights and their consent shall not be required for the taking of any corporate action.

Section 4.               Certain Restrictions.

(a)   Whenever Dividends are in arrears or the Corporation shall be in default of payment thereof, thereafter and until all accrued and unpaid Dividends, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid or set irrevocably aside for payment in full, and in addition to any and all other rights which any holder of shares of Series A Preferred Stock may have in such circumstances, the Corporation shall not:

(i)          declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration, any shares of capital stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock;

(ii)         declare or pay dividends on or make any other distributions on any shares of capital stock ranking on a parity as to dividends with the Series A Preferred Stock, unless dividends are paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled if the full dividends accrued thereon were to be paid;

(iii)        except as permitted by subparagraph (iv) of this Section 4(a), redeem or purchase or otherwise acquire for consideration shares of any capital stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any capital stock of the Corporation ranking junior (both as to dividends and upon liquidation, dissolution or winding up) to the Series A Preferred Stock; or

4

(iv)        purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of capital stock ranking on a parity with the Series A Preferred Stock (either as to dividends or upon liquidation, dissolution or winding up), except in accordance with a purchase offer made to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(b)   The Corporation shall not permit any Subsidiary (as hereinafter defined) of the Corporation to purchase or otherwise acquire for consideration any shares of capital stock of the Corporation unless the Corporation could, under Section 4(a), purchase or otherwise acquire such shares at such time and in such manner.  A “Subsidiary” of the Corporation shall mean any corporation or other entity of which securities or other ownership interests having ordinary voting power sufficient to elect a majority of the board of directors of such corporation or other entity or other persons performing similar functions are beneficially owned, directly or indirectly, by the Corporation or by any corporation or other entity that is otherwise controlled by the Corporation.

(c)   The Corporation shall not issue any shares of Series A Preferred Stock except upon exercise of Rights issued pursuant to that certain Rights Agreement dated as of March 23, 2011, by and between the Corporation and Mellon Investor Services LLC, as Rights Agent, as it may be amended from time to time, a copy of which is (i) on file with the Secretary of the Corporation at its principal executive office and shall be made available to stockholders of record without charge upon written request therefor addressed to said Secretary and (ii) available from the Securities and Exchange Commission at www.sec.gov, or upon the exchange of Rights in accordance with the agreement.  Notwithstanding the foregoing sentence, nothing contained in the provisions of this Certificate of Designations shall prohibit or restrict the Corporation from issuing for any purpose any series of preferred shares with rights and privileges similar to, different from, or greater than, those of the Series A Preferred Stock.

Section 5.               Reacquired Shares.  Any shares of Series A Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof.  All such shares upon their retirement and cancellation shall become authorized but unissued shares of preferred stock, without designation as to series, and such shares may be reissued as part of a new series of preferred stock to be created by resolution or resolutions of the Board of Directors.

Section 6.               Liquidation, Dissolution or Winding Up.  Upon any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, no distribution shall be made (a) to the holders of shares ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received for each share of Series A Preferred Stock, subject to adjustment as hereinafter provided,

5

(i) $1,000 plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment or, (ii) if greater than the amount specified in clause (a)(i) of this sentence, an amount equal to one thousand (1,000) times the aggregate amount to be distributed per share to holders of Common Stock, as the same may be adjusted as hereinafter provided and, (b) to the holders of shares ranking on a parity upon liquidation, dissolution or winding up with the Series A Preferred Stock, unless simultaneously therewith distributions are made ratably on the Series A Preferred Stock and all other shares of such parity stock in proportion to the total amounts to which the holders of shares of Series A Preferred Stock are entitled under clause (a)(i) of this sentence and to which the holders of such parity shares are entitled, in each case upon such liquidation, dissolution or winding up.  The amount to which holders of Series A Preferred Stock may be entitled upon liquidation, dissolution or winding up of the Corporation pursuant to clause (a)(i) of the foregoing sentence is hereinafter referred to as the “Participating Liquidation Amount” and the multiple of the amount to be distributed to holders of shares of Common Stock upon the liquidation, dissolution or winding up of the Corporation applicable pursuant to said clause to the determination of the Participating Liquidation Amount, as said multiple may be adjusted from time to time as hereinafter provided, is hereinafter referred to as the “Liquidation Multiple.”  In the event the Corporation shall at any time after the Effective Date declare or pay any dividend on Common Stock payable in shares of Common Stock, or effect a subdivision or split or a combination, consolidation or reverse split of the outstanding shares of Common Stock into a greater or lesser number of shares of Common Stock, then, in each such case, the Liquidation Multiple thereafter applicable to the determination of the Participating Liquidation Amount to which holders of Series A Preferred Stock shall be entitled after such event shall be the Liquidation Multiple applicable immediately prior to such event multiplied by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 7.               Certain Reclassifications and Other Events.

(a)   In the event that holders of shares of Common Stock receive after the Effective Date in respect of their shares of Common Stock any share of capital stock of the Corporation (other than any share of Common Stock), whether by way of reclassification, recapitalization, reorganization, dividend or other distribution or otherwise (a “Transaction”), then, and in each such event, the dividend rights, voting rights and rights upon the liquidation, dissolution or winding up of the Corporation of the shares of Series A Preferred Stock shall be adjusted so that after such event the holders of Series A Preferred Stock shall be entitled, in respect of each share of Series A Preferred Stock held, in addition to such rights in respect thereof to which such holder was entitled immediately prior to such adjustment, to (i) such additional dividends as equal to the Dividend Multiple in effect immediately prior to such Transaction multiplied by the additional dividends which the holder of a share of Common Stock shall be entitled to receive by virtue of the receipt in the Transaction of such capital stock, (ii) such additional voting rights as equal to the Vote Multiple in effect immediately prior to such Transaction multiplied by the additional voting rights which the holder of a share of

6

Common Stock shall be entitled to receive by virtue of the receipt in the Transaction of such capital stock and (iii) such additional distributions upon liquidation, dissolution or winding up of the Corporation as equal to the Liquidation Multiple in effect immediately prior to such Transaction multiplied by the additional amount which the holder of a share of Common Stock shall be entitled to receive upon liquidation, dissolution or winding up of the Corporation by virtue of the receipt in the Transaction of such capital stock, as the case may be, all as provided by the terms of such capital stock.

(b)   In the event that holders of shares of Common Stock receive after the Effective Date in respect of their shares of Common Stock any right or warrant to purchase Common Stock (including as such a right, for all purposes of this paragraph, any security convertible into or exchangeable for Common Stock) at a purchase price per share less than the Fair Market Value of a share of Common Stock on the date of issuance of such right or warrant, then and in each such event the dividend rights, voting rights and rights upon the liquidation, dissolution or winding up of the Corporation of the shares of Series A Preferred Stock shall each be adjusted so that after such event the Dividend Multiple, the Vote Multiple and the Liquidation Multiple shall each be the product of the Dividend Multiple, the Vote Multiple and the Liquidation Multiple, as the case may be, in effect immediately prior to such event multiplied by a fraction the numerator of which shall be the number of shares of Common Stock outstanding immediately before such issuance of rights or warrants plus the maximum number of shares of Common Stock which could be acquired upon exercise in full of all such rights or warrants and the denominator of which shall be the number of shares of Common Stock outstanding immediately before such issuance of rights or warrants plus the number of shares of Common Stock which could be purchased, at the Fair Market Value of the Common Stock at the time of such issuance, by the maximum aggregate consideration payable upon exercise in full of all such rights or warrants.

(c)   In the event that holders of shares of Common Stock receive after the Effective Date in respect of their shares of Common Stock any right or warrant to purchase capital stock of the Corporation (other than shares of Common Stock), including as such a right, for all purposes of this paragraph, any security convertible into or exchangeable for capital stock of the Corporation (other than Common Stock), at a purchase price per share less than the Fair Market Value of such shares of capital stock on the date of issuance of such right or warrant, then and in each such event the dividend rights, voting rights and rights upon liquidation, dissolution or winding up of the Corporation of the shares of Series A Preferred Stock shall each be adjusted so that after such event each holder of a share of Series A Preferred Stock shall be entitled, in respect of each share of Series A Preferred Stock held, in addition to such rights in respect thereof to which such holder was entitled immediately prior to such event, to receive (i) such additional dividends as equal to the Dividend Multiple in effect immediately prior to such event multiplied by the additional dividends to which the holder of a share of Common Stock shall be entitled upon exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction (as hereinafter defined), (ii) such additional voting rights as equal to the Vote Multiple in effect immediately prior to such event multiplied by the additional voting rights to which the holder of a share of Common Stock shall be entitled upon

7

exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction and (iii) such additional distributions upon liquidation, dissolution or winding up of the Corporation as equal to the Liquidation Multiple in effect immediately prior to such event multiplied by the additional amount which the holder of a share of Common Stock shall be entitled to receive upon liquidation, dissolution or winding up of the Corporation upon exercise of such right or warrant by virtue of the capital stock which could be acquired upon such exercise and multiplied again by the Discount Fraction.  For purposes of this paragraph, the “Discount Fraction” shall be a fraction the numerator of which shall be the difference between the Fair Market Value of a share of the capital stock subject to a right or warrant distributed to holders of shares of Common Stock as contemplated by this paragraph immediately after the distribution thereof and the purchase price per share for such share of capital stock pursuant to such right or warrant and the denominator of which shall be the Fair Market Value of a share of such capital stock immediately after the distribution of such right or warrant.

(d)   For purposes of this Certificate of Designations, the “Fair Market Value” of a share of capital stock of the Corporation (including a share of Common Stock) on any date shall be deemed to be the average of the daily closing prices per share thereof of such stock over the thirty (30) consecutive Trading Days (as hereinafter defined) immediately prior to such date; provided, however, that, in the event that the Fair Market Value of any such share of capital stock is to be determined as of a date that is within thirty (30) Trading Days after (i) the ex-dividend date for a dividend or distribution on stock payable in shares of such stock or securities convertible into shares of such stock, or (ii) the effective date of any subdivision, split, combination, consolidation, reverse stock split or reclassification of such stock, then, and in each such case, the Fair Market Value shall be appropriately adjusted by the Board of Directors to take into account such dividend, distribution, subdivision, split, combination, consolidation, reverse stock split or reclassification.  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 applicable transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange); or, if the shares are not listed or admitted to trading on the New York Stock Exchange, as reported in the applicable transaction reporting system with respect to securities listed on the principal national securities exchange on which the shares are listed or admitted to trading; or, if the shares are not listed or admitted to trading on any national securities exchange, the last quoted price (or, if not so quoted, the average of the high bid and low asked prices) in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotation System or such other quotation reporting system then in use; or if no bids for such shares are so quoted, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the shares selected by the Board of Directors.  The term “Trading Day” shall mean a day on which the principal national securities exchange on which the shares are listed or admitted to trading is open for the transaction of business or, if the shares are not listed or admitted to trading on any national securities exchange, on which the New York Stock Exchange or such other national securities exchange as may be selected by the Board of Directors.  If the shares

8

are not publicly held or not so listed or traded on any day within the period of thirty (30) Trading Days applicable to the determination of Fair Market Value thereof as aforesaid, “Fair Market Value” shall mean the fair market value thereof per share as determined in good faith by the Board of Directors.  In either case referred to in the foregoing sentence, the determination of Fair Market Value shall be described in a statement filed with the Secretary of the Corporation.

Section 8.               Consolidation, Merger, Combination or Other Transaction  In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each outstanding share of Series A Preferred Stock shall at the same time be similarly exchanged for or changed into the aggregate amount of stock, securities, cash and/or other property (payable in like kind), as the case may be, for which or into which each share of Common Stock is changed or exchanged multiplied by the highest of the Vote Multiple, the Dividend Multiple or the Liquidation Multiple in effect immediately prior to such event.

Section 9.               Effective Time of Adjustments.

(a)   Adjustments to the Series A Preferred Stock required by the provisions hereof shall be effective as of the time at which the event requiring such adjustments occurs.

(b)   The Corporation shall give prompt written notice to each holder of a share of Series A Preferred Stock of the effect of any adjustment to the voting rights, dividend rights or rights upon liquidation, dissolution or winding up of the Corporation of such shares required by the provisions of this Certificate of Designations.  Notwithstanding the foregoing sentence, the failure of the Corporation to give such notice shall not affect the validity of or the force or effect of or the requirement for such adjustment.

Section 10.             No Redemption.  The shares of Series A Preferred Stock shall not be redeemable at the option of the Corporation or any holder thereof.  Notwithstanding the foregoing sentence, the Corporation may acquire shares of Series A Preferred Stock in any other manner permitted by law, the provisions hereof and the By-laws of the Corporation.

Section 11.             Ranking.  Unless otherwise provided in the By-laws of the Corporation, or a certificate of designations relating to a subsequent series of preferred stock of the Corporation, the Series A Preferred Stock shall rank junior to all other series of the Corporation’s preferred stock as to the payment of dividends and the distribution of assets on liquidation, dissolution or winding up and senior to the Common Stock.

Section 12.             Amendment.  The provisions hereof, the Certificate of Incorporation of the Corporation and the By-laws of the Corporation shall not be amended in any manner which would adversely affect the rights, privileges or powers of

9

the Series A Preferred Stock without, in addition to any other vote of stockholders required by law, the affirmative vote of the holders of two-thirds of the outstanding shares of Series A Preferred Stock, voting separately as a single class.

Section 13.             Fractional Shares.  Shares representing Series A Preferred Stock may, but are not required to, be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and have the benefit of all other rights of holders of shares of Series A Preferred Stock.  Any reference in this Certificate of Designations to shares of Series A Preferred Stock shall be deemed also to refer to fractions of shares of Series A Preferred Stock.

AS PROVIDED IN THE RIGHTS AGREEMENT REFERRED

TO BELOW, RIGHTS ISSUED TO OR BENEFICIALLY OWNED

BY ACQUIRING PERSONS OR THEIR AFFILIATES OR

ASSOCIATES (AS SUCH TERMS ARE DEFINED IN THE

RIGHTS AGREEMENT) OR ANY SUBSEQUENT HOLDER OF

SUCH RIGHTS SHALL BE NULL AND VOID AND MAY NOT

BE EXERCISED OR TRANSFERRED TO ANY PERSON.

IRON MOUNTAIN INCORPORATED

SUMMARY OF RIGHTS

TO PURCHASE SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

On March 23, 2011, the Board of Directors of Iron Mountain Incorporated, a Delaware corporation (referred to as the “Company,” “we,” or “us”), authorized the issuance of one Preferred Share Purchase Right (a “Right” and collectively, the “Rights”) for each outstanding share of the Company’s common stock, par value $0.01 per share (the “Common Stock”).  Each Right, once exercisable, entitles the registered holder to purchase one one-thousandth (1/1000) of a share of preferred stock designated as Series A Junior Participating Preferred Stock, par value $0.01 per share (the “Preferred Stock”), at a price of $120.00 per one one-thousandth (1/1000) of a share (“Exercise Price”), subject to certain adjustments.  The issuance was made effective as of April 1, 2011 to our stockholders of record on that date (the “Record Date”).

The description and terms of the Rights are set forth in a Rights Agreement (the “Rights Agreement”), dated as of March 23, 2011, by and between the Company and Mellon Investor Services LLC (operating with the service name “BNY Shareowner Services”), a New Jersey limited liability company, as Rights Agent (the “Rights Agent”).  For those interested in the specific terms of the Rights Agreement, we provide the following summary description.  Please note, however, that this description is only a summary, and is not complete, and should be read together with the entire Rights Agreement, which has been filed with the Securities and Exchange Commission as an exhibit to a Registration Statement on Form 8-A dated March 24, 2011.  A copy of the agreement is available free of charge from the Company.

As discussed below, initially the Rights will not be exercisable, certificates representing the Rights will not be sent to our stockholders and the Rights will automatically trade with our Common Stock.

Holder of a Right Is Not Deemed a Stockholder.  Until a Right becomes exercisable and is exercised or exchanged pursuant to the terms of the Rights Agreement, the holder of a Right, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends.

Exercisability.  Prior to the Distribution Date (as defined in this paragraph), the Rights will not be exercisable and will not be transferable apart from our Common Stock.  Unless earlier redeemed by our Board of Directors, the Rights will become exercisable upon the close of business on the day (the “Distribution Date”) which is the earlier of:

·                  the tenth day following a public announcement that a person or group of affiliated or associated persons, with certain exceptions as described below, has acquired beneficial ownership of 15% or more of our outstanding voting shares (an “Acquiring Person”); and

·                  the tenth business day after the date of the commencement by any person (other than an Exempt Person, as defined in the Rights Agreement) of a tender or exchange offer, the consummation of which would result in such person or group of affiliated or associated persons becoming an Acquiring Person prior, subject to the ability of our Board of Directors to establish a later date.

Acquiring Person.  An Acquiring Person does not include:

·                  the Company or any of our subsidiaries;

·                  any employee benefit plan or employee stock plan of the Company or of any or our subsidiaries or any trust or other entity organized, appointed, established or holding voting shares for or pursuant to the terms of any such plan;

·                  any person or group of affiliated or associated persons who, immediately prior to the date of the Rights Agreement, is the beneficial owner of 15% or more of our shares of voting stock then outstanding (provided that any such person or group shall become an Acquiring Person upon acquisition of an additional 0.25% or more of our voting shares, unless such acquisition of additional voting shares is pursuant to a dividend or distribution paid or made by the Company on our outstanding voting stock or pursuant to a split or subdivision of our outstanding voting stock); or

·                  any person or group of affiliated or associated persons whose ownership of 15% or more of our shares of voting stock then outstanding results solely from (i) any action or transaction or transactions approved by our Board of Directors before such person or group became an Acquiring Person or (ii) a reduction in the number of our issued and outstanding voting shares pursuant to a transaction or transactions approved by our Board of Directors (provided that any such person or group shall become an Acquiring Person upon acquisition of an additional 0.25% or more of our voting shares, unless such acquisition of additional voting shares is pursuant to a dividend or distribution paid or made by the Company on our outstanding voting stock or pursuant to a split or subdivision of our outstanding voting stock).

In addition, if our Board of Directors determines in good faith that a person became an Acquiring Person inadvertently and without any intention of changing or influencing

2

control over our Company, then such person will not be deemed to become an Acquiring Person unless and until such person have failed to divest itself, as soon as practicable, of sufficient number of voting shares so that such person would no longer otherwise qualify as an Acquiring Person.

Evidence of Ownership of Rights.  The Rights will be evidenced by certificates for Common Stock together with this summary of rights or, in the case of uncertificated shares of Common Stock, by the book-entry account that evidences record ownership for such shares, each as registered in the names of holders of our Common Stock outstanding as of the Record Date, and not by separate Right certificates.  Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), new Common Stock certificates issued after the Record Date will contain a legend incorporating the Rights Agreement by reference.  With respect to any book-entry shares of Common Stock, such legend shall be included in a notice to the record holder of such shares.  Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), the surrender for transfer of any such certificate or book-entry shares, except as otherwise provided in the Rights Agreement, shall also constitute the transfer of the Rights associated with the Common Stock.  As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) will be mailed to holders of record of our Common Stock as of the close of business on the Distribution Date, and such separate certificates alone will evidence the Rights from and after the Distribution Date.

Expiration.  The Rights will expire upon the close of business on the earliest to occur of: (i) March 22, 2013, (ii) the date on which the Rights are redeemed or exchanged by the Company in accordance with the Rights Agreement and (iii) the date of the Company’s 2012 annual meeting of stockholders if requisite stockholder approval of the Rights Agreement is not obtained at such meeting.

Preferred Stock Material Provisions.  Each one one-thousandth (1/1,000) share of our Preferred Stock issuable upon exercise of the Rights:

·                  will be non-redeemable;

·                  unless otherwise provided in connection with the creation of a subsequent series of preferred shares, will be subordinate to any other series of our  preferred shares;

·                  will be entitled to receive when, as and if declared, a quarterly dividend in an amount equal to the greater of $0.001 per share or the cash dividends declared on one share of our Common Stock, and an amount equal to any non-cash dividends (other than dividends payable in equity securities) declared on one share of our Common Stock, in like kind;

·                  will be entitled to receive upon liquidation of the Company, a payment in an amount equal to the greater of $1.00 or the payment made per share of our Common Stock;

·                  will have one vote, voting together with the Common Stock; and

3

·                  will be entitled to receive in the event of any merger, consolidation or other transaction in which Common Stock is exchanged, the same amount received per share of our Common Stock.

The rights of our Preferred Stock as to dividends, liquidation and voting are protected by anti-dilution provisions.

Exercise Price Adjustments.  The Exercise Price of the Rights and the number of shares of Preferred Stock issuable upon exercise of the Rights are subject to certain adjustments from time to time in the event of a stock dividend on, or a subdivision or combination of, our Common Stock.  The Exercise Price for the Rights also is subject to adjustment in the event of extraordinary distributions of cash or other property to holders of Common Stock.

Flip In.  Unless the Rights are earlier redeemed, in the event that a person or group becomes an Acquiring Person, the Rights Agreement provides that proper provisions will be made so that each holder of record of a Right (other than Rights beneficially owned by an Acquiring Person and certain affiliates, associates and transferees thereof, whose Rights will thereupon become null and void) will thereafter have the right to receive, upon payment of the Exercise Price, that number of shares of the Preferred Stock having a fair market value determined in accordance with the Rights Agreement at the time of the transaction equal to approximately two times the Exercise Price (such value to be determined with reference to the fair market value of our Common Stock as provided in the Rights Agreement).

Flip Over.  Unless the Rights are earlier redeemed or exchanged, in the event that, after the time that a person or group becomes an Acquiring Person, we were to be acquired in a merger or other business combination (in which any shares of Common Stock are changed into or exchanged for other securities or assets) or more than 50% of the assets or earning power of the Company and its subsidiaries (taken as a whole) were to be sold or transferred in one or a series of related transactions, the Rights Agreement provides that proper provision will be made so that each holder of record of a Right (other than Rights beneficially owned by an Acquiring Person and certain affiliates, associates and transferees thereof, whose Rights will thereupon become null and void) will from and after such date have the right to receive, upon payment of the Exercise Price, that number of shares of common stock of the acquiring company having a fair market value at the time of such transaction determined in accordance with the Rights Agreement equal to approximately two times the Exercise Price.

Exchange.  At any time after any person or group becomes an Acquiring Person and prior to the acquisition by such person or group of 50% or more of the outstanding voting shares, our Board of Directors may exchange the Rights (other than Rights owned by such person or group which will have become null and void), in whole or in part, for shares of our Common Stock in accordance with the Rights Agreement.

Fractional Shares.  Fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one-thousandth of a share) may, at our election, be evidenced by depositary receipts.  We may also issue cash in lieu of fractional shares which are not integral multiples of one one-thousandth of a share.

4

Redemption.  At any time prior to such time as any person or group becomes an Acquiring Person, we may (at the direction of our Board of Directors) redeem the Rights in whole, but not in part, at a price of $0.01 per Right, subject to adjustment (the “Redemption Price”).  The redemption of the Rights by our Board of Directors may be made effective at such time and subject to such conditions, as our Board of Directors in its sole and absolute discretion may establish.  Notwithstanding anything contained in the Rights Agreement to the contrary, the Rights shall not be exercisable prior to the expiration of our right of redemption.  Immediately upon the effective time of the action of our Board of Directors authorizing redemption of the Rights, and without any further action and notice, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.  At the option of our Board of Directors, the Redemption Price may be paid in cash to each Rights holder or by the issuance of shares of Preferred Stock or Common Stock having a fair market value, determined in accordance with the Rights Agreement, equal to such cash payment.

Amendments.  For as long as the Rights are then redeemable, we (at the direction of our Board of Directors) may amend the Rights in any manner without the approval of any holders of the Rights.  At any time when the Rights are not then redeemable, we (at the direction of our Board of Directors) may amend the Rights without the approval of any holders of Rights (i) to cure any ambiguity, (ii) to correct or supplement any provision contained in the Rights Agreement which may be defective or inconsistent with any other provisions in the Rights Agreement or (iii) to change or supplement the provisions in the Rights Agreement in any manner which we may deem necessary or desirable, provided that no such supplement or amendment pursuant to this clause (iii) shall adversely affect the interest of the holders of Right Certificates (other than an Acquiring Person or any other person in whose hands Rights are null and void under the provisions of Section 7(e) of the Rights Agreement).
