WHEREAS, the Board of Directors of the Company has authorized and declared a dividend of one right (the "Right") in respect of each share of Common Stock (as hereinafter defined) of the Company outstanding as of the date the holding company reorganization is consummated (the "Record Time") and authorized the issuance of one Right in respect of each share of Common Stock issued after the Record Time and prior to the Separation Time (as hereinafter defined); WHEREAS, each Right entitles the holder thereof, after the Separation Date, to purchase securities of the Company (or, in certain cases, of certain other entities) pursuant to the terms and subject to the conditions set forth herein; and WHEREAS, in connection with the matters referred to herein, the Company desires to appoint the Rights Agent to act on behalf of the Company for the benefit of the holders of Rights, and the Rights Agent is willing so to act; NOW, THEREFORE, in consideration of the foregoing recitals and the mutual agreements set forth herein, and for the benefit of the holders of the Rights, the parties hereto hereby agree as follows: ARTICLE I - CERTAIN DEFINITIONS --------- ------------------- 1.1 Certain Definitions. For purposes of this Agreement, the following -------------------- terms have the meaning indicated: "Acquiring Person" shall mean any Person who is a Beneficial Owner of 10% or more of the outstanding shares of Common Stock; provided, however, that the -------- ------- term "Acquiring Person" shall not include (i) any Person who shall become the Beneficial Owner of 10% or more of the outstanding shares of Common Stock solely as a result of an acquisition by the Company of shares of Common Stock, until such time thereafter as such Person shall become the Beneficial Owner (other than by means of a stock dividend or stock split) of any additional shares of Common Stock; or (ii) any Person who shall become the Beneficial Owner of 10% or more of the outstanding shares of the Common Stock solely as a result of purchasing the Common Stock directly from the Company pursuant to a written agreement with the Company; or (iii) the Company, a wholly owned Subsidiary of the Company or any employee stock ownership or other employee benefit plan of the Company or a wholly owned Subsidiary of the Company. "Adverse Person" shall mean a Person declared as such by the Board of Directors of the Company, upon (i) a determination that such Person, alone or together with its Affiliates and Associates, has become the Beneficial Owner of 10% or more of the outstanding shares of Common Stock and (ii) a determination by the Board of Directors, including at least a majority of the Disinterested Directors, after reasonable inquiry and investigation, including such consultation with such persons as such directors shall deem appropriate, that (A) such Beneficial Ownership by such Person is intended to cause, is reasonably likely to cause or will cause the Company to repurchase the Common Stock beneficially owned by such Person or to cause pressure on the Company to take action or enter into a transaction or series of transactions which would provide such Person with short-term financial gain under circumstances where the Board of Directors determines that the best long-term interests of the Company and its stockholders, but for the actions and possible actions of such Person, would not be served by taking such action or entering into such transactions or series of transactions at that time or (B) such Beneficial Ownership is having or is reasonably likely to have a material adverse impact (including, but not limited to, impairment of relationships with customers or impairment of the Company's ability to maintain its competitive position) on the business or prospects of the Company; provided, however, that the Board of Directors of the Company may -------- determine not to declare a Person to be an Adverse Person if, prior to the time that such Person acquired 10% or more of the shares of Common Stock then outstanding (or, in the case of a Person who is the Beneficial Owner of 10% or more of the outstanding Common Stock as of the date of this Agreement, within 90 days following adoption of this Agreement), such Person provided to the Board of Directors in writing a statement of such Person's purpose and intentions in connection with the proposed acquisition of Common Stock, together with any other information reasonably requested of such Person by the Board of Directors, and the Board of Directors, based on such statement and reasonable inquiry and investigation, including consultation with such persons as the directors shall deem appropriate, determines to notify and notifies such Person in writing that it will not declare such Person to be an Adverse Person; provided further, that the -------- ------- Board of Directors, with the concurrence of a least a majority of the Disinterested Directors, may expressly condition in any manner a determination not to declare a Person an Adverse Person on such conditions as the Board of Directors may select, including without limitation, such Person's not acquiring more than a specified amount of stock and/or on such Person's not taking actions inconsistent with the purposes and intentions disclosed by such Person in the statement provided to the Board of Directors. In the event that the Board of Directors should at any time determine, upon reasonable inquiry and investigation, including consultation with such Persons as the directors shall deem appropriate, that such Person has not met or complied with any condition specified by the Board of Directors, the Board of Directors, with the concurrence of at least a majority of the Disinterested Directors, may at any time thereafter declare such Person to be an Adverse Person pursuant to the provisions hereof.

ARTICLE II - THE RIGHTS ---------- ---------- 2.1 Summary of Rights. As soon as practicable after the Record Time, the ----------------- Company will mail a copy of a letter to shareholders summarizing the terms of the Rights to each holder of record of Common Stock as of the Record Time, at such holder's address as shown by the records of the Company. 2.2 Legend on Common Stock Certificates. Certificates for the Common Stock ----------------------------------- issued after the Record Time but prior to the Separation Time shall evidence one Right for each share of Common Stock represented thereby and shall have impressed on, printed on, written on or otherwise affixed to them the following legend: Until the Separation Time (as defined in the Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement, dated as of the date the holding company reorganization is consummated (as such may be amended from time to time, the "Rights Agreement"), between Central Bancorp, Inc. (the "Company") and State Street Bank and Trust Company, the Rights Agent, the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be redeemed, may be exchanged for shares of Common Stock or other securities or assets of the Company, may expire, may become void (if they are "Beneficially Owned" by an "Acquiring Person" or "Adverse Person" or an Affiliate or Associate thereof, as such terms are defined in the Rights Agreement, or by any transferee of any of the foregoing) or may be evidenced by separate certificates and may no longer be evidenced by this certificate. The Company will mail or arrange for the mailing of a copy of the Rights Agreement to the holder of this certificate without charge within five days after the receipt of a written request therefor. Certificates representing shares of Common Stock that are issued and outstanding at the Record Time shall evidence one Right for each share of Common Stock evidenced thereby notwithstanding the absence of the foregoing legend. 2.3 Exercise of Rights; Separation of Rights. (a) Subject to adjustment as ----------------------------------------- herein set forth, each Right will entitle the holder thereof, after the Separation Time, to purchase, for the Exercise Price, one share of the Common Stock at the Exercise Price. (b) Until the Separation Time, (i) no Right may be exercised and (ii) each Right will be evidenced by the certificate for the associated share of Common Stock and will be transferable only together with, and will be transferred by a transfer of, such associated share. Notwithstanding any other provision of this Agreement, any Rights held by the Company or any of its Subsidiaries other than in fiduciary capacity shall not be exercisable. -5- Nothing in the preceding sentence shall be construed as limiting the right of the Company and its Subsidiaries to acquire or transfer Rights. (c) Subject to the terms and conditions herein set forth, after the Separation Time and prior to the Expiration Date, the Rights (i) may be exercised, and (ii) may be transferred independently of the shares of Common Stock in respect of which they were originally issued. Promptly following the Separation Time, the Rights Agent will mail to each holder of record of Common Stock as of the Separation Time, at such holder's address as shown by the records of the Company (the Company hereby agreeing to furnish copies of such records to the Rights Agent for this purpose), (x) a certificate (a "Rights Certificate") in substantially the form of Exhibit A hereto appropriately completed, representing the number of rights held by such holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any national securities exchange or other self-regulatory organization (as such terms are used under the Exchange Act) on which the Rights may from time to time be listed or through which the Rights may from time to time be traded, or to conform to usage, and (y) a disclosure statement describing the Rights. (d) Subject to Sections 2.3(b) and 5.10, Rights may be exercised on any Business Day after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent the Rights Certificate evidencing such Rights with an election to exercise (an "Election to Exercise") substantially in the form attached to the Rights Certificate duly completed, accompanied by payment in cash, or by certified or official bank check or money order payable to the order of the Company, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised together with a sum sufficient to cover any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for shares or depositary receipts (or both) in a name other than that of the holder of the Rights being exercised. (e) Upon receipt of a Rights Certificate, with an Election to Exercise accompanied by payment as set forth in Section 2.3(d) above, and subject to the conditions set forth in this Agreement, the Rights Agent will thereupon promptly (i)(A) requisition from a transfer agent for the stock or other securities purchasable upon exercise of the Rights certificates evidencing such number of shares or other securities to be purchased (the Company hereby irrevocably authorizing its transfer agents to comply with all such requisitions) and (B) if the Company elects pursuant to Section 5.5 hereof not to issue certificates representing fractional shares, requisition from the depositary selected by the Company depositary receipts representing the fractional shares to be purchased or requisition from the Company the amount of cash to be paid in lieu of fractional shares in accordance with Section 5.5 hereof and (ii) after receipt of such certificates, depositary receipts and/or cash, deliver the same to or upon the order of the registered holder of such Rights Certificate, registered (in the case of certificates or depositary receipts) in such name or names as may be designated by such holder. (f) In case the holder of any Rights shall exercise less than all the Rights evidenced by such holder's Rights Certificate, a new Rights Certificate evidencing the Rights which remain unexercised will be issued by the Rights Agent to such holder or to such holder's duly authorized assigns. (g) The Company covenants and agrees that it will (i) cause to be kept available until the Expiration Date out of its authorized and unissued shares of capital stock a number of shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Rights; (ii) immediately upon the occurrence of the Separation Time, take all such action as may be necessary to obtain the approval of such regulatory agency or agencies as may be required by law for the issuance of shares of the Common Stock upon the exercise of Rights hereunder, if required by law; (iii) take all such action as may be necessary to ensure that all shares delivered upon exercise of Rights shall, at the time of delivery thereof (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered and fully paid and nonassessable; (iv) take all such action as may be necessary to ensure that all securities other than shares delivered upon exercise of Rights shall, at the time of delivery thereof (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered and valid and binding obligations of the issuer thereof; (v) take all such action as may be necessary to comply with any applicable requirements of the General Laws of Massachusetts, the Securities Act of 1933 or the Exchange Act, and the rules and regulations thereunder, and any other applicable law, rule or regulation, in -6- connection with the issuance of any shares upon exercise of Rights; (vi) use its best efforts to cause all shares and other securities issued upon exercise of Rights to be listed on a national securities exchange or traded in the over-the-counter market, as reported by NASDAQ or another self-regulatory organization or registered securities information processor (as such terms are used under the Exchange Act), upon issuance; and (vii) pay when due and payable any and all federal and state transfer taxes and charges which may be payable in respect of the original issuance or delivery of the Rights Certificates or of any shares issued upon the exercise of Rights, provided that the Company shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for shares in a name other than that of the holder of the Rights being transferred or exercised. 2.4 Adjustments to Exercise Price; Number of Rights. (a) In the event the ------------------------------------------------ Company shall at any time after the Record Time and prior to the Separation Time (i) declare or pay a dividend on Common Stock payable in Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares of Common Stock, then (x) the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of shares of Common Stock (the "Expansion Factor") that a holder of one share of Common Stock immediately prior to such dividend, subdivision or combination would hold thereafter as a result thereof and (y) each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor, and (z) the adjusted number of Rights will be deemed to be distributed among the shares of Common Stock with respect to which the original Rights were associated (if they remain outstanding) and the shares issued in respect of such dividend, subdivision or combination, so that each such share of Common Stock will have exactly one Right associated with it. Each adjustment made pursuant to this paragraph shall be made as of the payment or effective date for the applicable dividend, subdivision or combination. In the event the Company shall at any time after the Record Time and prior to the Separation Time issue any shares of Common Stock otherwise than in a transaction referred to in the preceding paragraph, each such share of Common Stock so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such share. (b) In the event the Company shall at any time after the Record Time and prior to the Separation Time issue or distribute any securities or assets in respect of, in lieu of or in exchange for Common Stock (other than pursuant to a regular periodic cash dividend or a dividend paid solely in Common Stock) whether by dividend, in a reclassification or recapitalization (including any such transaction involving a merger, consolidation or binding share exchange), or otherwise, the Company shall make such adjustments, if any, in the Exercise Price, number of Rights and/or securities or other property purchasable upon exercise of Rights as the Board of Directors of the Company, in its sole discretion, may deem to be appropriate under the circumstances in order to adequately protect the interests of the holders of Rights generally, and the Company and the Rights Agent shall amend this Agreement as necessary to provide for such adjustments. (c) Each adjustment to the Exercise Price made pursuant to this Section 2.4 shall be calculated to the nearest cent. Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.4, the Company shall (i) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment, (ii) promptly file with the Rights Agent and with each transfer agent for the Common Stock a copy of such certificate and (iii) mail a brief summary thereof to each holder of Rights. (d) Irrespective of any adjustment or change in the securities purchasable upon exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the securities so purchasable which were expressed in the initial Rights Certificates issued hereunder. 2.5 Date on Which Exercise is Effective. Each person in whose name any -------------------------------------- certificate for shares issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the shares represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Exercise Price for such Rights (and any applicable taxes and other governmental charges payable by the exercising holder hereunder) was made; provided, however, -------- ------- that if the date of such surrender and payment is a date upon which the stock transfer books of the Company are closed, such 7 person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the stock transfer books of the Company are open. 2.6 Execution, Authentication, Delivery and Dating of Rights Certificates. ---------------------------------------------------------------------- (a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature and delivery of such Rights Certificates. Promptly after the Company learns of the Separation Time, the Company will notify the Rights Agent of such Separation Time and will deliver Rights Certificates executed by the Company to the Rights Agent for countersignature, and the Rights Agent shall manually countersign and deliver such Rights Certificates to the holders of the Rights pursuant to Section 2.3(c) hereof. No Rights Certificate shall be valid for any purpose until manually countersigned by the Rights Agent. (b) Each Rights Certificate shall be dated the date of countersignature thereof by the Rights Agent. 2.7 Registration, Registration of Transfer and Exchange. (a) After the ------------------------------------------------------ Separation Time, the Company will cause to be kept a register (the "Rights Register") in which, subject to such reasonable regulations as it may prescribe, the Company will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed "Rights Registrar" for the purpose of maintaining the Rights Register for the Company and registering Rights and transfers of Rights after the Separation Time as herein provided. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times after the Separation Time. After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of Section 2.7(c) below, the Company will execute, and the Rights Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificate so surrendered. (b) Except as otherwise provided in Section 3.1(b) hereof, all Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of the Company, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange. (c) Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company or the Rights Agent, as the case may be, duly executed by the holder thereof or such holder's attorney duly authorized in writing. As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. (d) The Company shall not be required to register the transfer or exchange of any Rights after the Rights have been redeemed pursuant to Section 5.1 hereof or become void pursuant to Section 3.1(b) hereof. 2.8 Mutilated, Destroyed, Lost and Stolen Rights Certificates. (a) If any ---------------------------------------------------------- mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Company shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so surrendered. -8- (b) If there shall be delivered to the Company and the Rights Agent prior to the Expiration Time (i) evidence to their satisfaction of the destruction, loss or theft of any Rights Certificate and (ii) such security or indemnity as may be required by them to save each of them and any of their agents harmless, then, in the absence of notice to the Company or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, ---- ---- the Company shall execute and upon its request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen. (c) As a condition to the issuance of any new Rights Certificate under this Section 2.8, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Rights Agent) connected therewith. (d) Every new Rights Certificate issued pursuant to this Section 2.8 in lieu of any mutilated, destroyed, lost or stolen Rights Certificate shall evidence an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Rights Certificate shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Rights duly issued hereunder. 2.9 Persons Deemed Owners. Prior to due presentment of a Rights Certificate --------------------- (or, prior to the Separation Time, the associated Common Stock certificate) for registration of transfer, the Company, the Rights Agent and any agent of the Company or the Rights Agent may deem and treat the person in whose name such Rights Certificate (or, prior to the Separation Time, such Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary. As used in this Agreement, unless the context otherwise requires, the term "holder" of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, the associated shares of Common Stock). 2.10 Delivery and Cancellation of Certificates. All Rights Certificates ------------------------------------------- surrendered upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The Company may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly cancelled by the Rights Agent. No Rights Certificates shall be countersigned in lieu of or in exchange for any Rights Certificates cancelled as provided in this Section 2.10, except as expressly permitted by this Agreement. The Rights Agent shall return all cancelled Rights Certificates to the Company. 2.11 Agreement of Rights Holders. Every holder of Rights by accepting the ---------------------------- same consents and agrees with the Company and the Rights Agent and with every other holder of Rights that: (a) prior to the Separation Time, each Right will be transferable only together with, and will be transferred by a transfer of, the associated share of Common Stock; (b) after the Separation Time, the Rights Certificates will be transferable only on the Rights Register as provided herein; (c) prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Stock certificate) for registration of transfer, the Company, the Rights Agent and any agent of the Company or the Rights Agent may deem and treat the person in whose name the Rights Certificate (or, prior to the Separation time, the associated Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary; (d) Rights beneficially owned by certain Persons will under the circumstances set forth in Section 3.1(b) become void; and -9- (e) This Agreement may be supplemented or amended from time to time pursuant to Section 2.4(b) or 5.4 hereof. ARTICLE III - ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN ----------- ------------------------------------------------- TRANSACTIONS ------------- 3.1 Distribution Date. (a) In the event that prior to the Expiration Time a ----------------- Distribution Date shall occur, then, if applicable law does not preclude Rights owned by certain Persons referred to in Section 3.1(b) hereof to become void pursuant to the provisions thereof, the Company shall take such action as shall be necessary to ensure and provide that, except as provided below, each Right shall constitute the right to purchase from the Company, upon exercise thereof in accordance with the terms hereof (but subject to Sections 5.1 and 5.10 hereof), that number of shares of Common Stock having an aggregate Market Price on the Distribution Date equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in order to protect the interests of the holders of Rights generally in the event that on or after such Distribution Date an event of a type analogous to any of the events described in Section 2.4(a) or (b) shall have occurred with respect to the Common Stock). (b) Notwithstanding the foregoing, to the extent permitted by applicable law, any Rights that are or were Beneficially Owned on or after the Distribution Date by an Acquiring Person, an Adverse Person, or an Affiliate or Associate thereof or by a transferee, direct or indirect, of any of the foregoing shall become void and any holder of such Rights (including transferees) shall thereafter have no rights to exercise or transfer such Rights. For purposes of the preceding sentence, a transferee of an Acquiring Person, Adverse Person or Affiliate or Associate thereof shall include only a Person who (i) becomes a transferee after the Acquiring Person or Adverse Person becomes such or (ii) becomes a transferee prior to or concurrently with the Acquiring Person or Adverse Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person or Adverse Person to holders of equity interests in such Acquiring Person or Adverse Person or to any Person with whom the Acquiring Person or Adverse Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 3.1(b). If any Rights Certificate is presented for assignment or exercise and the Person presenting the same does not complete the certification set forth at the end of the form of assignment or notice of election to exercise and provide such additional evidence of the identity of the Beneficial Owner and its Affiliates and Associates (or former Beneficial Owners and their Affiliates and Associates) as the Company shall reasonably request, then the Company shall be entitled to conclusively deem the Beneficial Owner thereof to be an Acquiring Person or an Adverse Person, or an Affiliate or Associate thereof or a transferee of any of the foregoing and accordingly will, to the extent permitted by applicable law, deem the Rights evidenced thereby to be void and not transferable or exercisable. (c) The Board of Directors of the Company may, at its option, at any time after a Distribution Date and prior to the time that an Acquiring Person or an Adverse Person becomes the Beneficial Owner of more than 50% of the outstanding shares of Common Stock, but only if applicable law does not preclude Rights owned by certain Persons referred to in Section 3.1(b) hereof to become void pursuant to the provisions thereof, elect to exchange all (but not less than all) of the then outstanding Rights (which shall not include Rights that have become void pursuant to the provisions of Section 3.1(b)) for shares of Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted in order to protect the interests of holders of Rights generally in the event that after the Separation Time an event of a type analogous to any of the events described in Section 2.4(a) or (b) shall have occurred with respect to the Common Stock (such exchange ratio, as adjusted from time to time, being hereinafter referred to as the "Exchange Ratio"). Immediately upon the action of the Board of Directors of the Company electing to exchange the Rights, without any further action and without any notice, the right to exercise the Rights will terminate and each Right will thereafter represent only the right to receive a number of shares of Common Stock equal to the Exchange Ratio. Promptly after the action of the Board of Directors electing to exchange the Rights, the Company shall give notice thereof (specifying the steps to be taken to receive shares of Common Stock in exchange for Rights) to the Rights Agent and the holders of the then outstanding Rights by mailing such notice in accordance with Section 5.9. -10- (d) In the event that there shall not be sufficient treasury shares or authorized but unissued shares of Common Stock of the Company to permit the exercise or exchange in full of the Rights in accordance with Section 3.1(a) or (c), the Company shall take such action as shall be necessary to ensure and provide, to the extent permitted by applicable law and any agreements or instruments in effect on the Distribution Date to which it is a party, that each Right shall thereafter constitute the right to receive, (x) at the Company's option, either (A) in return for the Exercise Price, debt or equity securities or other assets (or a combination thereof) having a fair value equal to twice the Exercise Price, or (B) without payment of consideration (except as otherwise required by applicable law), debt or equity securities or other assets (or a combination thereof) having a fair value equal to the Exercise Price, or (y) if the Board of Directors of the Company elects to exchange the Rights in accordance with Section 3.1(c), debt or equity securities or other assets (or a combination thereof) having a fair value equal to the product of the Market Price of a share of Common Stock on the Distribution Date times the Exchange Ratio in effect on the Distribution Date, where in any case set forth in (x) or (y) above the fair value of such debt or equity securities or other assets shall be as determined in good faith by the Board of Directors of the Company, after consultation with a nationally recognized investment banking firm. 3.2 Flip-over. (a) Prior to the Expiration Time the Company shall not enter --------- into any agreement with any Acquiring Person, any Adverse Person or any Affiliate or Associate of an Acquiring Person or Adverse Person with respect to, or consummate or permit to occur, any Flip-over Transaction or Event, unless and until it shall have entered into a supplemental agreement with the Person engaging in such Flip-over Transaction or Event (the "Flip-over Entity"), for the benefit of the holders of the Rights, providing that, upon consummation or occurrence of the Flip-over Transaction or Event (i) each Right shall thereafter constitute the right to purchase from the Flip-over Entity, upon exercise thereof in accordance with the terms hereof, that number of shares of Flip-over Stock of the Flip-over Entity having an aggregate Market Price on the date of consummation or occurrence of such Flip-over Transaction or Event equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in order to protect the interests of the holders of Rights generally in the event that after such date of consummation or occurrence an event of a type analogous to any of the events described in Section 2.4(a) or (b) shall have occurred with respect to the Flip-over Stock) and (ii) the Flip-over Entity shall thereafter be liable for, and shall assume, by virtue of such Flip-over Transaction or Event and such supplemental agreement, all the obligations and duties of the Company pursuant to this Agreement. The provisions of this Section 3.2 shall apply to successive Flip-over Transactions or Events. (b) Prior to the Expiration Time, unless the Rights will be redeemed pursuant to Section 5.1 hereof in connection therewith, the Company shall not enter into any agreement with respect to, or consummate or permit to occur, any Flip-over Transaction or Event if at the time thereof there are any rights, warrants or securities outstanding or any other arrangements, agreements or instruments which would eliminate or otherwise diminish in any respect the benefits intended to be afforded by this Agreement to the holders of Rights upon consummation or occurrence of such transaction or event. ARTICLE IV - THE RIGHTS AGENT ---------- ---------------- 4.1 General. (a) The Company hereby appoints the Rights Agent to act as ------- agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company agrees to pay to the Rights Agent reasonable compensation as shall be agreed to in writing from time to time for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses (including expenses incurred by the Rights Agent under Section 4.4) and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability. (b) The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any certificate for securities purchasable upon exercise of Rights, Rights Certificate, certificate for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, -11- 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. 4.2 Merger or Consolidation or Change of Name of Rights Agent. (a) Any ------------------------------------------------------------ corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any corporation succeeding to the shareholder services business of the Rights Agent or any successor Rights Agent, will be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. In case, at the time such successor Rights Agent succeeds to the agency created by this Agreement, any of the Rights Certificates have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates have not been countersigned, any successor Rights Agent may countersign such Rights 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 Rights Certificates will have the full force provided in the Rights Certificates and in this Agreement. (b) In case at any time the name of the Rights Agent is changed and at such time any of the Rights Certificates have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in is changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. 4.3 Duties of Rights Agent. The Rights Agent undertakes the duties and ----------------------- obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound: (a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel will be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion. (b) Whenever in the performance of its duties under this Agreement the Rights Agent deems it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by a person 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 Company and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate. (c) The Rights Agent will be liable hereunder only for its own negligence, bad faith or willful misconduct. (d) The Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the certificates for securities purchasable upon exercise of Rights or the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and will be deemed to have been made by the Company only. (e) The Rights Agent will not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity or execution of any certificate for securities purchasable upon exercise of Rights or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Section 3.1(b) hereof) or any adjustment required under the provisions of Section 2.4, 3.1 or 3.2 hereof or -12- responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.4 describing any such adjustment); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any securities purchasable upon exercise of Rights or any Rights or as to whether any securities purchasable upon exercise of Rights will, when issued, be duly and validly authorized, executed, issued and delivered and fully paid and nonassessable. (f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement. (g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be the Chairman of the Board, the President or any Vice President or the Secretary or any Assistance Secretary or the Treasurer or any Assistant Treasurer of the Company, and to apply to such persons for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such person. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent under this Rights Agreement and the date on and/or after which such action shall be taken or such omission shall be effective. Until the Rights Agent has received written instructions in response to such application specifying the action to be taken or omitted, the Rights Agent shall not be liable for any inaction or omission related to the subject of the proposal included in any such application. (h) The Rights Agent and any shareholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Stock, Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not the Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity. (i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent will not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof. 4.4 Change of Rights Agent. The Rights Agent may resign and be discharged ----------------------- from its duties under this Agreement upon 60 days' notice (or such lesser notice as is acceptable to the Company) in writing mailed to the Company and to each transfer agent of Common Stock by registered or certified mail, and to the holders of the Rights in accordance with Section 5.9. The Company may remove the Rights Agent upon 60 days' notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Rights in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Company will appoint a successor to the Rights Agent. If the Company fails to make such appointment within a period of 30 days after 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 any Rights (which holder shall, with such notice, submit such holder's Rights Certificate for inspection by the Company), then the holder of any Rights or the Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or or any other state of the United States which is authorized under such laws to exercise the powers of the Rights Agent contemplated by this Agreement and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000. After appointment, the successor Rights Agent will be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent 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 -13- appointment, the Company will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing to the holders of the Rights. Failure to give any notice provided for in this Section 4.4, 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. ARTICLE V - MISCELLANEOUS --------- ------------- 5.1 Redemption. (a) The Board of Directors of the Company may, at its ---------- option, at any time prior to the Distribution Date, or ten days thereafter, subject to extension by a vote of two-thirds of the Board of Directors, elect to redeem all (but not less than all) the then outstanding Rights at the Redemption Price. (b) Immediately upon the action of the Board of Directors of the Company electing to redeem the Rights, without any further action and without any notice, the right to exercise the Rights will terminate and each Right will thereafter represent only the right to receive the Redemption Price in cash. Promptly after the action of the Board of Directors electing to redeem, and thereby redeeming, the Rights, the Company shall give notice of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice in accordance with Section 5.9. 5.2 Expiration. No Person shall have any rights pursuant to this Agreement ---------- or any Right after the Expiration Time, except, if the Rights are redeemed, as provided in Section 5.1 hereof. 5.3 Issuance of New Rights Certificates.

The Company and the Rights Agent may from --------------------------- time to time supplement or amend this Agreement without the approval of any holder of Rights (i) in any respect prior to the Distribution Date (other than to change the Redemption Price or the Expiration Time, except as contemplated elsewhere herein), (ii) to make any changes following the close of business on the Distribution Date which the Company may deem necessary or desirable and which shall not materially adversely affect the interests of the holders of Rights generally or (iii) in order to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with any other provisions herein or otherwise defective. The Rights Agent will duly execute and deliver any supplement or amendment hereto requested by the Company which satisfies the terms of the preceding sentence. 5.5 Fractional Shares. If the Company elects not to issue certificates ------------------ representing fractional shares upon exercise of Rights, the Company shall, in lieu thereof, (a) evidence such fractional shares by depositary receipts issued pursuant to an appropriate agreement between the Company and a depositary selected by it, provided that such agreement shall provide that each holder of a depositary receipt shall have all of the rights, privileges and preferences to which such holder would be entitled as a beneficial owner of such fractional share, or (b) pay to the registered holder of such Rights the same fraction of the Market Price (determined as of the date of exercise) of one share of the stock issuable upon such exercise. 5.6 Rights of Action. Subject to the terms of this Agreement, rights of ---------------- action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights; and any holder of any Rights, without the consent of the Rights Agent or of the holder of any other Rights, may on such holder's own behalf and for such holder's own benefit and the benefit of other holders of Rights, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, such holder's right to exercise such holder's Rights in the manner provided in such holder's Rights 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 -14- of this Agreement and will be entitled to specific performance of the obligations of, and injunctive relief against actual or threatened violations of the obligations of, any Person subject to this Agreement. 5.7 Holder of Rights Not Deemed a Shareholder.
