RIGHTS AGREEMENT

RIGHTS AGREEMENT, dated as of September 25, 2003 (the “Agreement”), between North Pittsburgh Systems, Inc., a Pennsylvania corporation (the “Company”), and ▇▇▇▇▇ Fargo Bank Minnesota, N.A., a National Association (the “Rights Agent”).

The Board of Directors of the Company (the “Board of Directors”) has authorized and declared a dividend of one Right (as such term is defined below) for each share of Common Stock, par value $.15625 per share, of the Company (the “Common Shares”) outstanding as of the Close of Business on October 6, 2003 (the “Record Date”), and has authorized the issuance of one Right with respect to each Common Share that shall become outstanding between the Record Date and the earliest of the Distribution Date, the Redemption Date, the Exchange Date and the Final Expiration Date (as such terms are defined below), each Right representing the right to purchase one one-hundredth of a share of Class A Junior Participating Preferred Stock of the Company having the rights, powers and preferences set forth in the form of Statement with Respect to Shares attached hereto as Exhibit A, upon the terms and subject to the conditions hereinafter set forth (the “Rights”).

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

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

(a) “Acquiring Person” shall mean any Person (as such term is defined below) who or which, together with all Affiliates and Associates (as such terms are defined below) of such Person, shall be the Beneficial Owner (as such term is defined below) of 15% or more of the Common Shares then outstanding, but shall not include (i) the Company, (ii) any Subsidiary (as such term is defined below) of the Company, or (iii) any employee benefit plan of the Company or of any Subsidiary of the Company or any entity organized, appointed or established by the Company for or pursuant to the terms of any such plan. Notwithstanding the foregoing, (i) no Person shall become an “Acquiring Person” solely as the result of an acquisition of Common Shares by the Company which, by reducing the number of shares outstanding, increases the proportionate number of shares beneficially owned by such Person to 15% or more of the Common Shares then outstanding; provided, however, that if a Person becomes the Beneficial Owner of 15% or more of the Common Shares then outstanding by reason of share acquisitions by the Company and shall, after such share acquisitions, become the Beneficial Owner of any additional Common Shares (other than pursuant to a stock split or stock dividend by the Company to all holders of Common Shares), then such Person shall be deemed to be an “Acquiring Person”; and (ii) if the Board of Directors of the Company determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this paragraph, has become such inadvertently, and such Person divests as promptly as practicable a sufficient number of Common Shares so that such Person would no longer be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this paragraph, then such Person shall not be deemed to have become an “Acquiring Person” for any purposes of this Agreement.

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

(i) which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or indirectly, within the meaning of Rule 13d-3 or Rule 13d-5 of the General Rules and Regulations under the Exchange Act, as in effect on the date of this Agreement;

(ii) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), or upon the exercise of conversion rights, exchange rights, rights (other than these Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially own”, securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange;

(iii) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to vote or dispose of pursuant to any agreement, arrangement or understanding; provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially own”, any security under this subparagraph (iii) as a result of an agreement, arrangement or understanding to vote such security if such agreement, arrangement or understanding (1) arises solely from a revocable proxy given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations of the Exchange Act and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report); or

(iv) which are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) with which such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities) for the purpose of acquiring, holding, voting (except pursuant to a revocable proxy as described in the proviso to subparagraph (iii) of this paragraph (c)) or disposing of any securities of the Company.

If a Person shall be deemed to be the Beneficial Owner of any securities which are not outstanding, such securities shall be deemed to be outstanding for purposes of determining the percentage of Common Shares beneficially owned by such Person.

(d) “Business Day” shall mean any day other than a Saturday, Sunday or a day on which banking institutions in the Commonwealth of Pennsylvania are authorized or obligated by law or executive order to close.

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

(f) “Common Shares” when used with reference to the Company (or without express reference to another Person) shall mean the shares of Common Stock, par value $.15625 per share, of the Company or any other shares of capital stock of the Company into which the Common Shares are reclassified or changed. “Common Shares” when used with reference to any Person other than the Company shall mean the capital stock or other equity securities or equity or other beneficial interests of such Person with the greatest aggregate voting power.

(g) “Common Stock Equivalent” shall mean a share, or fraction of a share, of any authorized class or series of preferred stock of the Company having dividend, voting, liquidation and other rights which result, in the judgment of the Board of Directors, in such share, or fraction of a share, being approximately equivalent in value to one Common Share as of the Event Date (as such term is defined below); provided, however, that, if in the judgment of the Board of Directors there are not sufficient authorized but unissued shares of preferred stock available for the creation of Common Stock Equivalents, “Common Stock Equivalent” shall mean such cash, reduction in Purchase Price (as such term is defined below), other equity securities, debt securities, other assets or any combination of the foregoing, that the Board of Directors shall determine to be approximately equivalent in value to one Common Share as of the Event Date. As used herein, “Event Date” shall mean (i) for purposes of any determination made pursuant to Section 11(a)(iii) hereof, the date of occurrence of the event described in Section 11(a)(ii) hereof and (ii) for purposes of any determination made pursuant to Section 25(c) hereof, the Exchange Date (as such term is defined below).

The Rights Agent shall have no duty to supervise, and shall in no event be liable for, the acts or omissions of any such Co-Rights Agent.

Section 3. Issue of Right Certificates. (a) Until the earlier of (i) the Close of Business on the tenth day after the Share Acquisition Date or (ii) the Close of Business on the tenth business day (or such later day 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 that a tender or exchange offer by any Person is first published, sent or given within the meaning of Rule 14d-2(a) of the General Rules and Regulations under the Exchange Act if, upon consummation thereof, such Person would be an Acquiring Person (the earlier of such dates, including any such date which is after the date of this Agreement and prior to the issuance of the Rights, being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced (subject to the provisions of paragraph (b) of this Section 3) by the certificates for Common Shares registered in the names of the holders thereof (which certificates shall also be deemed to be certificates for Rights) and not by separate certificates, and (y) the Rights will be transferable only in connection with the transfer of the underlying Common Shares. As soon as practicable after the Distribution Date, the Rights Agent will send, by first-class, insured, postage prepaid mail, to each record holder of Common Shares as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, one or more Right certificates, in substantially the form of Exhibit B hereto (the “Right Certificates”), evidencing one Right for each Common Share so held, subject to adjustment as provided herein. As of the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

(b) As promptly as practicable after the Record Date, the Company will send a copy of a Summary of Rights in substantially the form attached hereto as Exhibit C (the “Summary of Rights”), by first-class, postage prepaid mail, to each record holder of Common Shares as of the Close of Business on the Record Date, at the address of such holder shown on the records of the Company. With respect to certificates for Common Shares outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for Common Shares together with a copy of the Summary of Rights, and the registered holders of Common Shares shall also be the registered holders of the associated Rights. Until the Distribution Date (or the earliest of the Redemption Date, Exchange Date or Final Expiration Date), the surrender for transfer of any certificate for Common Shares outstanding on the Record Date, with or without a copy of the Summary of Rights attached thereto, shall also constitute the transfer of the Rights associated with the Common Shares represented by such certificate.

(c) Rights shall be issued in respect of all Common Shares which become outstanding (including, without limitation, reacquired Common Shares referred to in the last sentence of this paragraph (c)) after the Record Date but prior to the earliest of the Distribution Date, the Redemption Date, the Exchange Date or the Final Expiration Date. Certificates representing such Common Shares shall also be deemed to be certificates for Rights, and shall bear the following legend:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Rights Agreement between North Pittsburgh Systems, Inc. (the “Company”) and ▇▇▇▇▇ Fargo Bank Minnesota, N.A., dated as of September 25, 2003 (the “Rights Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Rights Agreement without charge promptly after receipt of a written request therefor. As described in the Rights Agreement, Rights beneficially owned by (i) an Acquiring Person or any Associate or Affiliate thereof (as such terms are defined in the Rights Agreement), (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such or (iii) under certain circumstances, a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee before or concurrently with the Acquiring Person becoming such, shall become null and void.

With respect to such certificates containing the foregoing legend, until the earliest of the Distribution Date, the Redemption Date, the Exchange Date or the Final Expiration Date, the Rights associated with the Common Shares represented by such certificates shall be evidenced by such certificates alone and the registered holders of Common Shares shall also be the holders of the associated Rights, and the surrender for transfer of any such certificates shall also constitute the transfer of the Rights associated with the Common Shares represented thereby. In the event that the Company purchases or acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares shall be deemed cancelled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Shares which are no longer outstanding.

Section 4. Form of Right Certificates. The Right Certificates (and the forms of election to purchase shares and of assignment to be printed on the reverse thereof) shall be substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 23 hereof, the Right Certificates shall entitle the holders thereof to purchase such number of one one-hundredths of a Preferred Share as shall be set forth therein at the price per one

one-hundredth of a share set forth therein (the “Purchase Price”), but the number of such shares and the Purchase Price shall be subject to adjustment as provided herein.

Section 5. Countersignature and Registration.

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

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

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

(a) Subject to the provisions of Section 7(e) and Section 15 hereof, at any time after the Close of Business on the Distribution Date, and at or prior to the Close of Business on the earliest of the Redemption Date, the Exchange Date or the Final Expiration Date, any Right Certificate or Certificates may be transferred, split up, combined or exchanged for another Right Certificate or Right Certificates, entitling the registered holder to purchase a like number of Preferred Shares as the Right Certificate or Right Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Right Certificate shall make such request in writing delivered to the Rights Agent, and shall surrender the Right Certificate or Right Certificates to be transferred, split up, combined or exchanged at the principal office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate or Right Certificates until the registered holder shall have properly completed and signed the certificate contained in the form of assignment set forth on the reverse side of each such Right Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably

request. Thereupon the Rights Agent shall, subject to Section 7(e) and Section 15 hereof, countersign and deliver to the person entitled thereto a Right Certificate or Right Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Right Certificates.

(b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and, at the Company’s request, reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Right Certificate if mutilated, the Company will execute and deliver a new Right Certificate of like tenor to the Rights Agent for delivery to the registered owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

(a) The Rights shall not be exercisable prior to the Distribution Date. The registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date upon surrender of the Right Certificate, with the form of election to purchase on the reverse side thereof duly executed, to the Rights Agent at the principal office or offices of the Rights Agent designated for such purpose, together with payment of the Purchase Price for each one one-hundredth of a Preferred Share as to which the Rights are exercised, at or prior to the earliest of (i) the Close of Business on October 6, 2013 (the “Final Expiration Date”), (ii) the time at which the Rights are redeemed as provided in Section 24 hereof (the “Redemption Date”) or (iii) the time at which the Rights are exchanged as provided in Section 25 hereof (the “Exchange Date”).

(b) The Purchase Price for each one one-hundredth of a Preferred Share pursuant to the exercise of a Right shall initially be $60, shall be subject to adjustment from time to time as provided in Sections 11 and 13 hereof and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below.

(c) Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase duly executed, accompanied by payment of the Purchase Price for the shares to be purchased as set forth below and an amount equal to any applicable transfer tax required to be paid by the holder of such Right Certificate in accordance with Section 9(e) hereof, the Rights Agent shall, subject to Section 21(j) hereof, thereupon promptly (i)(A) requisition from any transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent for such shares) certificates for the number of Preferred Shares to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the Preferred Shares issuable upon exercise of the Rights hereunder into a depositary, requisition from the depositary agent depositary receipts representing such number of one one-hundredths of a Preferred Share as are to be purchased (in which case certificates for the Preferred Shares represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company will direct

the depositary agent to comply with such request, (ii) requisition from the Company the amount of cash, if any, to be paid in lieu of issuance of fractional shares in accordance with Section 15 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by such holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Right Certificate. The payment of the Purchase Price shall be made in cash or by certified or bank official check or money order payable to the order of the Company. In the event that the Company is obligated to issue other securities of the Company pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such other securities are available for distribution by the Rights Agent, if and when necessary to comply with this Agreement.

(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 by the Rights Agent and delivered to the registered holder of such Right Certificate or to his duly authorized assigns, subject to the provisions of Sections 6 and 15 hereof.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the occurrence of the event described in Section 11(a)(ii) hereof, any Rights beneficially owned by (i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which a majority of the Board of Directors has determined is part of a plan, agreement, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e), shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. No Right Certificate shall be issued pursuant to Section 3 hereof that represents Rights beneficially owned by an Acquiring Person whose Rights would be void pursuant to the preceding sentence or any Associate or Affiliate thereof and no Right Certificate shall be issued at any time upon the transfer of any Rights to an Acquiring Person whose Rights would be void pursuant to the preceding sentence or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate. Any Right Certificate delivered to the Rights Agent for transfer to any of the foregoing Persons, or which represents void Rights, shall be cancelled. The Company shall use reasonable efforts to effect compliance with the provisions of this Section 7(e), but shall have no liability to any holder of Right Certificates or other Person as a result of its failure to make any determinations with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder.

(f) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported transfer as set forth in

Section 6 hereof or exercise as set forth in this Section 7 unless such registered holder shall have (i) duly and properly completed and signed the certificate contained in the form of assignment or election to purchase set forth on the reverse side of the Right Certificate surrendered for such assignment or exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request.

Section 8. Cancellation and Destruction of Right Certificates. All Right Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Right Certificates to the Company, or shall, at the written request of the Company and after any Securities and Exchange Commission required retention period, destroy such cancelled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. Reservation and Availability of Preferred Shares.

(a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued Preferred Shares and/or any authorized and issued Preferred Shares held in its treasury, the number of Preferred Shares that will be sufficient to permit the exercise in full of all outstanding Rights.

(b) The Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all Preferred Shares issued or reserved for issuance to be listed, upon official notice of issuance, upon the principal national securities exchange, if any, upon which the Common Shares are listed or, if the principal market for the Common Shares is not on any national securities exchange, to be listed or admitted to trading on the NASDAQ National Market System (the “NASDAQ NMS”) or any successor thereto or other comparable nationally recognized securities quotation system.

(c) The Company shall use its best efforts to (i) file, as soon as practicable following the earliest date after the occurrence of the event described in Section 11(a)(ii) hereof on which the consideration to be delivered by the Company has been determined in accordance with Section 11(a)(ii) or 11(a)(iii) hereof, as the case may be, a registration statement under the Securities Act with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) subject to Section 25 hereof, cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities and (B) the Final Expiration Date. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or “blue sky” laws of the various states in connection with the exercisability of the Rights. The Company may temporarily

suspend, for a period of time not to exceed ninety (90) days after the date described in clause (i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. In addition, if the Company shall determine that a registration statement is required following the Distribution Date but prior to the occurrence of the event described in Section 11(a)(ii) hereof, the Company may temporarily suspend the exercisability of the Rights until such time as a registration statement has been declared effective. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification in such jurisdiction shall not have been obtained, the exercise thereof shall not be permitted under applicable law or the requisite registration statement shall not have been declared effective.

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

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

Section 10. Preferred Shares Record Date. Each person in whose name any certificate for Preferred Shares is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Preferred Shares represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable transfer taxes) was made; provided, however, that if the date of such surrender and payment is a date upon which the transfer books of the Company with respect to the Preferred Shares are closed, such person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the transfer books of the Company for the Preferred Shares are open.

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

(a) (i) In the event the Company shall, at any time after the date of this Agreement, (A) declare a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares into a greater number of shares, (C) combine the outstanding Preferred Shares into a smaller number of shares or (D) issue any shares of its capital stock in a reclassification of the Preferred Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and in Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of Preferred Shares or shares of capital stock, as the case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive the aggregate number and kind of Preferred Shares or shares of capital stock, as the case may be, which he would have owned immediately after such dividend, subdivision, combination or reclassification if he had exercised such Right immediately prior to such date at a time when the transfer books of the Company for the Preferred Shares were open.

(ii) Subject to Sections 11(a)(iii) and 25 hereof, in the event that any Person shall become an Acquiring Person, then proper provision shall be made so that each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have a right to receive, upon exercise thereof at a price equal to the then current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right is then exercisable, in accordance with the terms of this Agreement and in lieu of Preferred Shares, such number of Common Shares as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-hundredths of a Preferred Share for which a Right is then exercisable and (y) dividing that product by 50% of the current market price (determined pursuant to Section 11(d)(i) hereof) per Common Share on the date such Person became an Acquiring Person.

(iii) Subject to Section 25 hereof, in the event that the number of Common Shares which are authorized by the Company’s Articles of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii), the Rights shall not be exercisable for Common Shares, but proper provision shall be made so that each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have a right to receive, upon exercise thereof in accordance with the terms of this Agreement at the price determined pursuant to the foregoing subparagraph (ii), such number of Common Stock Equivalents (or, in the judgment of the Board of Directors, such combination of Common Stock Equivalents and Common Shares) as shall equal the number of Common Shares determined pursuant to the foregoing subparagraph (ii).

(b) In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred Shares entitling them to subscribe for or purchase (for a period expiring within 45 calendar days after such record date) Preferred Shares (or shares having the same rights, privileges and preferences as the Preferred Shares (“equivalent preferred shares”)) or securities convertible into Preferred Shares or equivalent preferred shares at a price per Preferred Share or equivalent preferred share (or having a conversion price per share, if a security convertible into Preferred Shares or equivalent preferred shares) less than the current market price (as determined pursuant to Section 11(d)(ii) hereof) per Preferred Share on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of Preferred Shares outstanding on such record date, plus the number of Preferred Shares which the aggregate offering price of the total number of Preferred Shares so to be offered and/or equivalent preferred shares so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price and the denominator of which shall be the number of Preferred Shares outstanding on such record date, plus the number of additional Preferred Shares and/or equivalent preferred shares to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. Preferred Shares owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

(c) In case the Company shall fix a record date for a distribution to all holders of Preferred Shares (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation) of evidences of indebtedness, cash (other than a regular quarterly cash dividend), assets, stock (other than a dividend payable in Preferred Shares) or subscription rights, options or warrants (excluding those referred to in or excluded pursuant to Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the current market price (as determined pursuant to Section 11(d)(ii) hereof) per one one-hundredth of a Preferred Share on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes) of the portion of the cash, assets, stock or evidences of indebtedness so to be distributed or of such subscription rights, options or warrants applicable to one one-hundredth of a Preferred Share and the denominator of which shall be such current market price (as determined pursuant to Section 11(d)(ii) hereof) per one one-hundredth of a Preferred Share. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Purchase Price shall again be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

(d) (i) For the purposes of any computation hereunder, the “current market price” per Common Share on any date shall be deemed to be the average of the daily closing prices per Common Share for the 30 consecutive Trading Days (as such term is defined below) immediately prior to such date; provided, however, that in the event that the current market price per Common Share is determined during a period following the announcement by the issuer of such Common Shares of (A) a dividend or distribution on such Common Shares payable in such Common Shares or securities convertible into such Common Shares (other than the Rights) or (B) any subdivision, combination or reclassification of such Common Shares and prior to the expiration of 30 Trading Days after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the “current market price” shall be appropriately adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Common Shares are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Common Shares are listed or admitted to trading or, if the Common Shares are not listed or admitted to trading on any national securities exchange, the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the NASDAQ NMS or, if the Common Shares are not listed or admitted to trading on the NASDAQ NMS, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use, or, if on any such date the Common Shares are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Shares selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Common Shares, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used and shall be conclusive for all purposes. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the Common Shares are listed or admitted to trading is open for the transaction of business or, if the Common Shares are not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Shares are not publicly held or not so listed or traded, “current market price” per share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(ii) For the purpose of any computation hereunder, the “current market price” per Preferred Share shall be determined in the same manner as set forth above for the Common Shares in subparagraph (i) of this Section 11(d) (other than the last sentence thereof). If the current market price per Preferred Share cannot be determined in the manner provided above or if the Preferred Shares are not publicly held or listed or traded in a manner described in subparagraph (i) of this Section 11(d), the “current market price” per Preferred Share shall be conclusively deemed to be an amount equal to 100 times the current market price per Common Share (as appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Shares occurring after the date of this Agreement). If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, “current market price” per Preferred Share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest ten-thousandth of a Common Share or other share or one-millionth of a Preferred Share, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which requires such adjustment or (ii) the date of the expiration of the right to exercise any Rights.

(f) If as a result of an adjustment made pursuant to Section 11(a) or Section 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Preferred Shares, thereafter the number of such other shares so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Shares contained in this Section 11 and the provisions of Sections 6, 7, 9, 10, 13 and 15 with respect to the Preferred Shares shall apply on like terms to any such other shares.

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

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made pursuant to Sections 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one one-hundredths of a Preferred Share (calculated to the nearest one-millionth)

obtained by (i) multiplying (x) the number of one one-hundredths of a share covered by a Right immediately prior to this adjustment, by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price, and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in substitution for any adjustment in the number of Preferred Shares purchasable upon the exercise of a Right. Each of the Rights outstanding after such adjustment in the number of Rights shall be exercisable for the number of one one-hundredths of a Preferred Share for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, shall be at least 10 days later than the date of the public announcement.

If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Right Certificates on such record date Right Certificates evidencing, subject to Section 15 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all the Rights to which such holder shall be entitled after such adjustment. Right Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

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

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

(1) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the

Company may elect to defer until the occurrence of such event the issuing to the holder of any Right exercised after such record date of the Preferred Shares and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Shares and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due ▇▇▇▇ or other appropriate instrument evidencing such holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment.

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

(n) In the event that any time after the date of this Agreement and prior to the Distribution Date, the Company shall (i) declare or pay any dividend on the Common Shares payable in Common Shares or (ii) effect a subdivision, combination or consolidation of the Common Shares (by reclassification or otherwise than by payment of dividends in Common Shares) into a greater or lesser number of Common Shares, then in any such case (i) the number of one one-hundredths of a Preferred Share purchasable after such event upon proper exercise of each Right shall be determined by multiplying the number of one one-hundredths of a Preferred Share so purchasable immediately prior to such event by a fraction, the numerator of which is the number of Common Shares outstanding immediately before such event and the denominator of which is the number of Common Shares outstanding immediately after such event, and (ii) each Common Share outstanding immediately after such event shall have issued with respect to it that number of Rights which each Common Share outstanding immediately prior to such event had issued with respect to it. The adjustments provided for in this Section 11(n) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is effected.

Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Sections 11 and/or 13 hereof, the Company shall (a) promptly prepare a certificate setting forth such adjustment, and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Rights Agent and with each transfer agent for the Preferred Shares and the Common Shares a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate (or, if prior to the Distribution Date, to each holder of a certificate representing Common Shares) in accordance with Section 27 hereof. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained.

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

(a) In the event that, following the Share Acquisition Date, (x) the Company, directly or indirectly, shall consolidate with, or merge with and into, any other Person, and the Company shall not be the continuing or surviving corporation of such consolidation or merger, (y) any Person, directly or indirectly, shall consolidate with, or merge with and into, the Company, and the Company 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 Common Shares shall be changed into or exchanged for stock or other securities of any other Person (or of the Company) or cash or any other property, or (z) the Company, directly or indirectly, shall sell or otherwise transfer (or one or more of its Subsidiaries, directly or indirectly, shall sell or otherwise transfer), in one or more transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than the Company or one or more wholly owned Subsidiaries of the Company), then, and in each such case, proper provision shall be made so that (i) each holder of a Right (except as otherwise provided herein) shall thereafter have the right to receive, upon the exercise thereof at a price equal to the then current Purchase Price multiplied by the number of one one-hundredths of a Preferred Share for which a Right is then exercisable (without taking into account any adjustment previously made pursuant to Section 11(a)(ii) or 11(a)(iii) hereof), in accordance with the terms of this Agreement, such number of validly authorized and issued, fully paid, nonassessable and freely tradeable Common Shares of the Principal Party (as defined below), free and clear of any liens, encumbrances and other adverse claims and not subject to any rights of call or first refusal, as shall be equal to the result obtained by (1) multiplying the then current Purchase Price by the number of one one-hundredths of a Preferred Share for which a Right is then exercisable (without taking into account any adjustment previously made pursuant to Section 11(a)(ii) or 11(a)(iii) hereof) and (2) dividing that product by 50% of the current market price (determined pursuant to Section 11(d)(i) hereof) per Common Share of the Principal Party on the date of consummation of such consolidation, merger, sale or transfer; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such consolidation, merger, sale or transfer, all the obligations and duties of the Company pursuant to this Agreement; (iii) except for purposes of Section 1(f) hereof, the term “Company” shall thereafter be deemed to refer to such Principal Party; (iv) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of its Common Shares) in connection with the consummation of any such transaction as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to its Common Shares 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 (except as otherwise provided herein) shall thereupon be entitled to receive, upon exercise of a Right and payment of the Purchase Price, such cash, shares, rights, warrants and other property which such holder would have been entitled to receive had he, at the time of such transaction, owned the Common Shares of the Principal Party purchasable upon the exercise of a Right (after giving effect to the foregoing provisions of this Section 13(a)), 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 (v) the provisions of Sections 11(a)(ii) and 11(a)(iii) hereof shall be of no effect following the occurrence of any event described in clauses (x), (y) and (z) of this Section 13(a).

(b) “Principal Party” shall mean

(i) in the case of any merger described in clause (x) or (y) of Section 13(a), any Person that is the issuer of any securities into which Common Shares of the Company are converted in such merger, and if no securities are so issued, any Person that is a party to such merger that survives the merger;

(ii) in the case of any consolidation described in clause (x) or (y) of Section 13(a), any Person that directly controls, alone or with other Persons, a corporation that is consolidating with the Company; and

(iii) in the case of any transaction or transactions described in clause (z) of Section 13(a), any Person that receives any assets or earning power transferred pursuant to such transaction or transactions;

provided, however, that with respect to such Person (or, if there is more than one such Person, with respect to each such Person), (1) if the Common Shares of such Person are not at such time and have not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act (“Registered Common Shares”), or such Common Shares are deregistered as a consequence of any merger described in Section 13(a), or such Person is not a corporation, and such Person is (or, upon consummation of any merger described in Section 13(a), becomes) a direct or indirect Subsidiary of another Person which has Registered Common Shares outstanding, “Principal Party” shall refer to such other Person; (2) if the Common Shares of such Person are not Registered Common Shares, or such Common Shares are deregistered as a consequence of any merger described in Section 13(a), or such Person is not a corporation, and such Person is (or, upon consummation of any merger described in Section 13(a), becomes) a direct or indirect Subsidiary of another Person but is not a direct or indirect Subsidiary of another Person which has Registered Common Shares outstanding, “Principal Party” shall refer to the ultimate parent entity of such first-mentioned Person; (3) if the Common Shares of such Person are not Registered Common Shares, or such Common Shares are deregistered as a consequence of any merger described in Section 13(a), or such Person is not a corporation, and such Person is (or, upon consummation of any merger described in Section 13(a), becomes) directly or indirectly controlled by more than one Person, and one or more of such latter Persons have Registered Common Shares outstanding, “Principal Party” shall refer to whichever of such latter Persons is the issuer of outstanding Registered Common Shares having the greatest aggregate current market value (determined pursuant to Section 11(d)(i) hereof); or (4) if the Common Shares of such Person are not Registered Common Shares, or such Common Shares are deregistered as a consequence of any merger described in Section 13(a), or such Person is not a corporation, and such Person is (or, upon consummation of any merger described in Section 13(a), becomes) directly or indirectly controlled by more than one Person, and none of such latter Persons have Registered Common Shares outstanding, “Principal Party” shall refer to whichever ultimate parent entity is the entity having the greatest net assets;

provided, further, however, that if under the foregoing provisions of this Section 13(b) there shall for any reason be more than one Principal Party, “Principal Party” shall refer to whichever of such Persons is the issuer of outstanding Registered Common Shares having the greatest aggregate current market value (determined pursuant to Section 11(d)(i) hereof) or, if none of such Persons has Registered Common Shares outstanding, whichever of such Persons is the entity having the greatest net assets.

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

(d) The Company shall not consummate any such consolidation, merger, sale or transfer unless (1) at the time of and after such consummation the Principal Party shall have a sufficient number of authorized Common Shares which have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this Section 13 and (2) prior to such consummation the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in this Section 13 and further providing that, as soon as practicable after the date of any consolidation, merger or sale or transfer of assets mentioned in paragraph (a) of this Section 13, 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, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such filing and (B) remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Final Expiration Date, and similarly comply with applicable state securities or “blue sky” laws; and

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

Section 14. Additional Covenants.

(a) Except as expressly provided herein, no adjustment to the Purchase Price, the number of Preferred Shares or other securities for which a Right is exercisable or the number of Rights outstanding (except as permitted by Section 24 or Section 25 hereof) or any similar adjustment shall be made or be effective if such adjustment would have the effect of reducing or limiting the benefits the holders of the Rights would have had absent such

adjustment, including, without limitation, the benefits under Section 11(a)(ii) and Section 13 hereof, unless the terms of this Agreement are amended so as to preserve such benefits.

(b) The Company covenants and agrees that, following the Share Acquisition Date, except as permitted by Section 25 hereof, it shall not, directly or indirectly, take any action the purpose or effect of which is to eliminate or otherwise diminish in any material respect the benefits intended to be afforded by the Rights.

(c) The Company covenants and agrees that, following the Share Acquisition Date, it shall not consummate any of the transactions described in clauses (x), (y) and (z) of Section 13(a) hereof if (i) at the time of or after such consummation there are or would be any charter or by-law provisions or any rights, warrants or other instruments or securities outstanding or agreements in effect (whether of the Company or any other Person) or any other action taken (whether by the Company or any other Person) the purpose or effect of which is to eliminate or otherwise diminish in any material respect the benefits intended to be afforded by the Rights or (ii) the shareholders of the Principal Party shall have received, either prior to, simultaneously with, or after the consummation of such transaction, a distribution of Rights previously owned by the Principal Party or any of its Affiliates and Associates.

(d) The Company further covenants and agrees that, following the Share Acquisition Date, it shall not consummate any of the transactions described in clauses (x), (y) and (z) of Section 13(a) hereof unless prior thereto the Company and the Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement evidencing compliance with paragraph (c) above and further providing that the Principal Party covenants and agrees that it shall not, directly or indirectly, take any action the purpose or effect of which is to eliminate or otherwise diminish in any material respect the benefits intended to be afforded by the Rights. The provisions of this paragraph (d) and paragraph (c) above shall similarly apply to successive mergers, consolidations, sales or other transfers.

Section 15. Fractional Rights and Fractional Shares. (a) The Company shall not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For the purposes of this Section 15(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price of the Rights for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities

listed or admitted to trading on the NASDAQ NMS or, if the Common Shares are not listed or admitted to trading on the NASDAQ NMS, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company. If on any such date no such market maker is making a market in the Rights the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Company shall be used and shall be conclusive for all purposes.

(b) The Company shall not be required to issue fractions of Preferred Shares (other than fractions which are integral multiples of one one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares (other than fractions which are integral multiples of one one-hundredth of a Preferred Share). Fractions of Preferred Shares in integral multiples of one one-hundredth of a Preferred Share may, at the election of the Company, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Company and a depositary selected by it, provided that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of the Preferred Shares represented by such depositary receipts. In lieu of fractional Preferred Shares that are not integral multiples of one one-hundredth of a Preferred Share, the Company may pay to the registered holders of Right Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one one-hundredth of a Preferred Share. For purposes of this Section 15(b), the current market value of one one-hundredth of a Preferred Share shall be one one-hundredth of the closing price of a Preferred Share (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of such exercise.

(c) The holder of a Right by the acceptance of the Right expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 15.

Section 16. Rights of Action. All rights of action in respect of this Agreement are vested in the respective registered holders of the Right Certificates (and, prior to the Distribution Date, the registered holders of the Common Shares); and any registered holder of any Right Certificate (or, prior to the Distribution Date, of any of the Common Shares), without the consent of the Rights Agent or of the holder of any other Right Certificate (or, prior to the Distribution Date, of any of the Common Shares), may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Right Certificate in the manner provided in such Right Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

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

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

(b) after the Distribution Date, the Right Certificates will be transferable only on the registry books of the Rights Agent if surrendered at the office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer;

(c) subject to Sections 6(a) and 7(f) hereof, the Company and the Rights Agent may deem and treat the Person in whose name the Right Certificate (or, prior to the Distribution Date, the associated Common Shares certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificate or the associated Common Shares certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to the last sentence of Section 7(e) hereof, shall be required to be affected by any notice to the contrary; and

(d) notwithstanding anything in this Agreement to the contrary, neither the Company 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, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; provided, however, the Company must use its best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible.

Section 18. Right Certificate Holder Not Deemed a Shareholder. No holder, as such, of any Right Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the Preferred Shares or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Right Certificate be construed to confer upon the holder of any Right Certificate, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in Section 26 hereof), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof.

Section 19. Concerning the Rights Agent. (a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder in accordance with a fee schedule to be mutually agreed upon and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in

the administration and execution of this Agreement and the exercise and performance of its duties hereunder in accordance with such fee schedule. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without gross 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 hereunder. In no case will the Rights Agent be liable for special, indirect, incidental or consequential loss or damages of any kind whatsoever (including, but not limited to, lost profits), even if the Rights Agent has been advised of the possibility of such damages. The indemnity provided herein shall survive the termination of this Agreement and the exercise or expiration of the Rights.

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

Section 20. Merger or Consolidation or Change of Name of Rights Agent. (a) Any 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 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 22 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and in case at such time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

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

Section 21. Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of

which the Company and the holders of Right Certificates, by their acceptance thereof, shall be bound:

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full 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 shall deem 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 the President or any Vice President of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

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

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

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

(g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from the President or any Vice President of the Company, and to apply to such officers for advice or instructions in

connection with its duties, and it shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer.

(h) The Rights Agent and any shareholder, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other Person.

(i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself 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 for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

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

(k) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if it believes in good faith that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

Section 22. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days’ notice in writing mailed to the Company and, if instructed by the Company, to each transfer agent of the Common Shares and Preferred Shares by registered or certified mail, and, at the expense of the Company, to the holders of the Right Certificates by first-class mail. The Company 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 Shares and Preferred Shares by registered or certified mail, and to the holders of the Right Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company 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 Company), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a Person organized and doing business under the laws of the United States or of any State of the United States, in

good standing, having a principal office in the State of New York, which is authorized under such laws to exercise stock transfer powers and is subject to supervision or examination by federal or state authority and which has (or whose Affiliate has) at the time of such Person’s appointment as Rights Agent a combined capital and surplus of at least $50 million. 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 or conveyance, and perform any other act or deed, necessary for the purpose. Not later than the effective date of any such appointment the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares and the Preferred Shares, and mail a notice thereof in writing to the registered holders of the Right Certificates. Failure to give any notice provided for in this Section 22, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

Section 23. Issuance of New Right Certificates. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and/or the number or kind or class of shares 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 Common Shares following the Distribution Date and prior to the earliest of the Redemption Date, the Exchange Date and the Final Expiration Date, the Company (a) shall, with respect to Common Shares so issued or sold pursuant to the exercise of employee stock options or under any employee plan or arrangement outstanding, granted or awarded as of the Distribution Date, or upon the exercise, conversion or exchange of securities issued by the Company prior to such date, and (b) may, in any other case, if deemed necessary or appropriate by a majority of the Board of Directors, issue Right Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Right Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Right Certificates would be issued and (ii) no such Right Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

Section 24. Redemption. (a) The Board of Directors of the Company 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 the then outstanding Rights at a redemption price of $.01 per Right, appropriately adjusted to reflect any stock split, stock dividend, reclassification or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the “Redemption Price”). The redemption of the Rights 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. Without limiting the generality of the foregoing, the Company may, at its option, pay the Redemption Price in cash, Common Shares (based on the “current market price,” as defined in Section 11(d)(i) hereof, of the Common Shares at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors.

(b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights (or at such later time as the Board of Directors may establish for the effectiveness of such redemption), and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price. The Company shall promptly give public notice of any such redemption; provided, however, that the failure to give or any defect in such notice shall not affect the validity of such redemption. Within ten (10) days after the action of the Board of Directors ordering the redemption of 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 to the Rights Agent and to all such holders at their last address as it appears 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 Shares. 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 redemption will state the method by which the payment of the Redemption Price will be made.

(c) Neither the Company nor any of its Subsidiaries may redeem, acquire or purchase for value any Rights at any time in any manner except (i) pursuant to a redemption in accordance with this Section 24 or an exchange pursuant to Section 25 hereof or (ii) in connection with the purchase or other acquisition of Common Shares prior to the Distribution Date.

Section 25. Exchange. (a) Subject to paragraph (c) of this Section 25, the Board of Directors of the Company may, at its option, at any time following such time as any Person becomes an Acquiring Person, exchange all but not less than all of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof) for Common Shares at an exchange ratio of one Common Share per Right, appropriately adjusted to reflect any stock split, stock dividend, reclassification or similar transaction occurring after the date hereof (such exchange being hereinafter referred to as the “Exchange” and such exchange ratio being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect the Exchange at any time after any Person (other than the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any such Subsidiary, or any entity organized, appointed or established by the Company for or pursuant to the terms of any such plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of Common Shares aggregating 50% or more of the Common Shares then outstanding.

(b) Immediately upon the action of the Board of Directors of the Company authorizing the Exchange, and without any further action and without any notice, the right to exercise the Rights shall terminate and the only right thereafter of a holder of Rights included in the Exchange shall be to receive that number of Common Shares equal to the number of Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice of the Exchange; provided, however, that the failure to give or any defect in such notice shall not affect the validity of the Exchange. Within ten (10) days after the effectiveness of the Exchange pursuant to the first sentence of this Section 25(b), the Company shall mail a notice of Exchange to the Rights Agent and 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 will be effected.

(c) In the event that the number of Common Shares which are authorized by the Company’s Articles of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not sufficient to permit the Exchange, the Exchange Ratio shall equal one Common Stock Equivalent (in lieu of one Common Share) per Right. Alternatively, the Board of Directors of the Company may, at its option, determine that the Company shall (i) issue Common Shares in the Exchange to the extent Common Shares are available and (ii) utilize Common Stock Equivalents in the Exchange as provided above to the extent Common Shares are not available, in which case such Common Shares shall be allocated on such basis as the Board of Directors determines pursuant to Section 30 hereof.

(d) The Company shall not be required to issue fractions of Common Shares or to distribute certificates which evidence fractional Common Shares. In lieu of such fractional shares, there shall be paid to the registered holders of the Right Certificates with regard to which such fractional shares would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of one Common Share. For the purposes of this paragraph (d), the current market value of one Common Share shall be the closing price of a Common Share (as determined pursuant to Section 11(d)(i) hereof) for the Trading Day immediately prior to the Exchange Date.

Section 26. Notice of Certain Events. (a) In case the Company shall propose, at any time after the Distribution Date, (i) to pay any dividend payable in stock of any class to the holders of Preferred Shares or to make any other distribution to the holders of Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer to the holders of Preferred Shares rights, options or warrants to subscribe for or to purchase any additional Preferred Shares at less than the current market price of the Preferred Shares, or shares of stock of any class or any other securities, rights or options, (iii) to effect any reclassification of its Preferred Shares (other than a reclassification involving only the subdivision of outstanding Preferred Shares), (iv) to effect any consolidation or merger into or with, or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one or more transactions, of more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to, any other Person or Persons, or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Right Certificate, in accordance with Section 27 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, or distribution of rights, options or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the Preferred Shares, 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 20 days prior to the record date for determining holders of the Preferred Shares for purposes of such action, and in the case of any such other action, at least 20 days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Preferred Shares, whichever shall be the earlier.

(b) In case the event set forth in Section 11(a)(ii) of this Agreement shall occur, then (i) the Company shall as soon as practicable thereafter give to each holder of a Right Certificate, in accordance with Section 27 hereof, a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Section 11(a)(ii) hereof and (ii) all references in the preceding paragraph to Preferred Shares shall thereafter be deemed to refer to Common Shares or, if appropriate, to Common Stock Equivalents.

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

Section 28. Supplements and Amendments. Prior to the Share Acquisition Date, and subject to the last sentence of this Section 28, the Company and the Rights Agent shall, if the Company so directs, supplement or amend any provision of this Agreement, whether or not adverse to the holders of Rights, without any approval of the holders of Rights. From and after the Share Acquisition Date, and subject to the last sentence of this Section 28, the Company and the Rights Agent may from time to time supplement or amend this Agreement without any approval of the holders of Rights in order (i) to cure any ambiguity, (ii) to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, or (iii) to change or supplement the provisions herein to effectuate the purposes of this Agreement, or to make any other provisions with respect to the Rights, which, in either such

case, shall not materially adversely affect the interests of the holders of Rights (other than Acquiring Persons and Affiliates or Associates thereof). Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section 28, the Rights Agent shall execute such supplement or amendment; provided, however, that the Rights Agent may, but shall not be obligated to, enter into any such supplement or amendment which affects the Rights Agent’s own rights, duties, liabilities or obligations under this Agreement. Notwithstanding anything contained in this Agreement to the contrary, no supplement or amendment shall be made which decreases the Redemption Price.

Section 29. Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder.

All such actions, calculations, interpretations and determinations (including, for purpose of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Board of Directors in good faith shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties, and (y) not subject the Board of Directors to any liability to the holders of the Rights.

Section 31. Benefits of this Agreement. Nothing in this Agreement shall be construed to give to any Person other than the Company, the Rights Agent and the registered holders of the Right Certificates (and, prior to the Distribution Date, the Common Shares) any legal or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Right Certificates (and, prior to the Distribution Date, the Common Shares).

Section 32. 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.

RESOLVED, that pursuant and subject to the provisions of Article 5 of the Articles of Incorporation of the Corporation, as amended, there is hereby established a class of Preferred Stock to which the following provisions shall be applicable:

Class A Junior Participating Preferred Stock

Section 1. Designation. The class shall be designated as “Class A Junior Participating Preferred Stock” (hereinafter “this Class”).

Section 2. Number. The number of shares of this Class authorized to be issued is 151,000. Such number may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease shall reduce the number of shares of this Class to a number less than that of the shares then outstanding.

Section 3. Dividends and Distributions.

(A) Subject to the prior and superior rights of the holders of any shares of any class or series of Preferred Stock ranking prior and superior to this Class with respect to dividends, the holders of shares of this Class shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available therefor, quarterly dividends payable in cash on the 15th day of January, April, July and October in 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 this Class, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions (other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock by reclassification or otherwise), declared on the Common Stock, par value $.15625 per share, of the Corporation (the “Common Stock”) since the immediately preceding Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of this Class. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of shares of this Class were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) The Corporation shall declare a dividend or distribution on this Class as provided in paragraph (A) of this Section immediately after it declares a dividend or distribution

on the Common Stock (other than a dividend payable in shares of Common Stock); provided, however, that in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on this Class shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and be cumulative on outstanding shares of this Class from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of this Class, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date with respect to this Class, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of this Class entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of this Class 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 this Class entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 60 days prior to the date fixed for the payment thereof.

Section 4. Liquidation, Dissolution or Winding Up. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation (a “Liquidation”), no distribution shall be made (x) to the holders of Common Stock or any other shares of stock ranking junior (either as to dividends or upon Liquidation) to this Class unless, prior thereto, the holders of shares of this Class shall have received an amount per share equal to the greater of (i) $100, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, or (ii) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate amount to be distributed per share to holders of Common Stock or (y) to the holders of stock ranking on a parity (either as to dividends or upon Liquidation) with this Class, except distributions made ratably on this Class and all other such parity stock in proportion to the total amounts to which the holders of all such shares are entitled upon such Liquidation. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the aggregate amount to which holders of shares of this Class were entitled immediately prior to such event under clause (ii) of clause (x) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

For purposes of this Statement, the voluntary sale, lease, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property

or assets of the Corporation to, or a consolidation or merger of the Corporation with, one or more corporations shall not be deemed to be a Liquidation.

Section 5. Redemption. The shares of this Class shall not be redeemable.

Section 6. Voting Rights. The holders of shares of this Class shall have the following voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each share of this Class shall entitle the holder thereof to 100 votes on all matters submitted to a vote of the Common shareholders of the Corporation. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the number of votes per share to which holders of shares of this Class were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein, in the Articles of Incorporation of the Corporation or by law, the holders of shares of this Class and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of Common shareholders of the Corporation.

(C) (i) If at any time dividends on any shares of this Class shall be in arrears in an amount equal to six full quarterly dividends thereon, the holders of this Class and all other classes and/or series of Preferred Stock (in each case to the extent then entitled pursuant to the terms of such classes or series), voting together as one class, shall have the exclusive and special right to elect two directors of the Corporation, and the number of directors constituting the Board of Directors of the Corporation shall be increased by two (if not previously increased in connection with the right of other classes or series of Preferred Stock entitled to vote together with this Class to elect directors of the Corporation) for such purpose and, if necessary, the By-laws of the Corporation shall be deemed amended to so provide.

(ii) Whenever any such right of the holders of this Class shall have vested, such right may be exercised initially either at a special meeting of the holders of this Class and all other classes and/or series so entitled to vote, if any, called as hereinafter provided, or at any annual meeting of shareholders, and thereafter at annual meetings of shareholders. The right of the holders of this Class voting separately as a class with such other classes and/or series to elect members of the Board of Directors of the Corporation as aforesaid shall continue until such time as all dividends accrued on all shares of this Class shall have been paid in full, or declared and set apart for payment, at which time the special right

of the holders of this Class so to vote separately as a class with such other classes and/or series for the election of directors shall terminate, subject to revesting in the event of each and every subsequent occurrence of an arrearage specified in subparagraph (C)(i) above.

(iii) At any time when such special voting power shall have vested in the holders of this Class as provided in the preceding subparagraph (C)(i), the proper officer of the Corporation shall, upon the written request of the holders of record of at least 10% of the then outstanding voting power of shares of this Class and all other classes and/or series entitled to vote in the election of such directors addressed to the Secretary of the Corporation, call a special meeting of the holders of this Class for the purpose of electing directors pursuant to this paragraph (C). Such meeting shall be held at the earliest practicable date. If such meeting shall not be called by the proper officer of the Corporation within 20 days after personal service of such written request upon the Secretary of the Corporation, or within 20 days after mailing the same within the United States of America, by registered mail addressed to the Secretary of the Corporation at its principal office, then the holders of record of at least 10% of the then outstanding voting power of shares of this Class and all other classes and/or series entitled to vote in the election of such directors may designate in writing one of their number to call such meeting at the expense of the Corporation, and such meeting may be called by such person so designated by giving the notice required for annual meetings of shareholders. Any holder of this Class so designated shall have access to the stock books of the Corporation for the purpose of causing meetings of shareholders to be called pursuant to these provisions. Notwithstanding the provisions of this subparagraph (C)(iii), no such special meeting shall be called during the period within 90 days immediately preceding the date fixed for the next annual meeting of shareholders.

(iv) At any meeting held for the purpose of electing directors at which the holders of this Class and any other classes and/or series of Preferred Stock shall have the special right to elect directors as provided in this paragraph (C), the presence, in person or by proxy, of the holders of 50% of the voting power of the then outstanding aggregate number of shares of this Class and such other classes and/or series shall be required to constitute a quorum for the election of any director by the holders of such classes and/or series. At any such meeting or adjournment thereof, (a) the absence of a quorum shall not prevent the election of directors other than those to be elected by all such classes and/or series of Preferred Stock voting separately as a class, and the absence of a quorum for the election of such other directors shall not prevent the election of the directors to be elected by this Class and any other classes and/or series of Preferred Stock that may be voting with it separately as a class, and (b) in the absence of either or both such quorums, the holders of a majority of the voting power of the shares present in person or by proxy of the stock or stocks which lack a quorum shall have power to adjourn the meeting for the election of directors whom they are entitled to elect from time to time without notice other than announcement at the meeting until a quorum shall be present.

(v) During any period when the holders of this Class have the right to vote separately as a class for directors as provided in this paragraph (C), (1) the directors so elected by the holders of the one or more classes and/or series of Preferred Stock entitled to vote for such directors shall continue in office until the next succeeding annual meeting or until their successors, if any, are elected by such holders and qualify or, until termination of the right of the holders of the one or more classes and/or series of Preferred Stock entitled to vote for such directors to vote separately as a class for directors as provided in this paragraph (C) and (2) vacancies in the Board of Directors shall be filled only by vote of a majority (even if that be only a single director) of the remaining directors theretofore elected by the holders of the one or more classes and/or series of Preferred Stock which elected the directors whose office shall have become vacant or, if there be no such remaining director, directors to fill such vacancies shall be elected by the holders of the one or more classes and/or series of Preferred Stock entitled to vote for such directors at a special meeting called pursuant to the provisions of this paragraph (C). Immediately upon any termination of the right of the holders of this Class and any other classes and/or series of Preferred Stock to vote separately as a class for directors as provided in this paragraph (C), the term of office of the directors then in office so elected by the holders of this Class and any such other classes and/or series shall terminate. Whenever the term of office of the directors so elected by the holders of this Class and any such other classes and/or series shall terminate and the special voting power vested in the holders of this Class and any such other classes and/or series as provided in this paragraph (C) shall have terminated, the number of directors shall be such number as may be provided for in the by-laws irrespective of any increase made pursuant to the provisions of this paragraph (C).

(D) So long as any shares of this Class are outstanding, the Corporation shall not, without the consent of the holders of two-thirds of the outstanding shares of this Class, given by such holders as one class, and given by vote in person or by proxy at a meeting called for that purpose or given in writing, amend the Articles of Incorporation or adopt or amend any resolutions of the Board of Directors to alter or change the powers, preferences or special rights of this Class so as to affect them adversely.

(E) Except as provided herein, in the Articles of Incorporation of the Corporation or by law, holders of shares of this Class shall have no special voting rights and their consent shall not be required for taking any corporate action.

Section 7. Certain Restrictions.

(A) Whenever quarterly dividends or other dividends or distributions payable on this Class as provided in Section 3 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of this Class outstanding shall have been paid in full, 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 Common Stock or

any other shares of stock ranking junior (either as to dividends or upon Liquidation) to this Class;

(ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon Liquidation) with this Class, except dividends paid ratably on this Class 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;

(iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon Liquidation) with this Class; provided, however, that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon Liquidation) to this Class; or

(iv) purchase or otherwise acquire for consideration any shares of this Class, or any shares of stock ranking on a parity (either as to dividends or upon Liquidation) with this Class, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) 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 of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 7, purchase or otherwise acquire such shares at such time and in such manner.

Section 8. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of this Class shall at the same time be similarly exchanged for or changed into an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of this Class shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 9. Ranking. This Class shall rank junior to all other classes and series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets upon Liquidation, unless the terms of any such class or series shall provide otherwise.

Section 10. Fractional Shares. This Class may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and have the benefit of all other rights of holders of this Class.

Section 11. Other Rights. The holders of shares of this Class shall not have any other preferences or special rights.

EXHIBIT C TO RIGHTS AGREEMENT

SUMMARY OF RIGHTS TO PURCHASE

PREFERRED STOCK

On September 25, 2003, the Board of Directors of North Pittsburgh Systems, Inc. (the “Company”) declared a dividend distribution of one Right for each outstanding share of Common Stock, par value $.15625 per share, of the Company (the “Common Shares”) to shareholders of record on October 6, 2003 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company a unit (“Unit”) consisting of one one-hundredth of a share of Class A Junior Participating Preferred Stock, par value $1.00 per share, of the Company (the “Preferred Shares”), at a price of $60 per Unit (the “Purchase Price”), subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement (the “Rights Agreement”) between the Company and ▇▇▇▇▇ Fargo Bank Minnesota, N.A., as Rights Agent.

Initially, the Rights will be attached to all Common Share certificates representing Common Shares then outstanding, and no separate Right certificates will be distributed. Until the earlier to occur of (i) 10 days following a public announcement that a person or group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding Common Shares (an “Acquiring Person”), or (ii) 10 business days (or such later day as may be determined by action of the Board of Directors prior to such time as any person or group becomes an Acquiring Person) following the commencement of a tender offer or exchange offer if, upon consummation thereof, any person or group would be an Acquiring Person (the earlier of such dates being called the “Distribution Date”), the Rights will be evidenced, with respect to any of the Common Share certificates outstanding as of the Record Date, by such certificate together with a copy of this Summary of Rights. The date of announcement of the existence of an Acquiring Person referred to in clause (i) above is hereinafter referred to as the “Share Acquisition Date.”

The Rights Agreement provides that, until the Distribution Date, the Rights will be transferred with and only with the Common Share certificates. Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), new Common Share certificates issued after the Record Date upon transfer or new issuance of Common Shares will contain a notation incorporating the Rights Agreement by reference. Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), the surrender for transfer of any certificates for Common Shares outstanding as of the Record Date, with or without a copy of this Summary of Rights attached thereto, will also constitute the transfer of the Rights associated with the Common Shares represented by such certificate. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) will be mailed to holders of record of the Common Shares on the Distribution Date and, thereafter, such separate Right Certificates alone will evidence the Rights.

The Rights are not exercisable until the Distribution Date and will expire at the close of business on October 6, 2013, unless earlier redeemed or exchanged by the Company as described below.

In the event that any person or group of affiliated or associated persons becomes an Acquiring Person, the Rights Agreement provides that proper provision shall be made so that each holder of a Right, except as provided below, shall thereafter have the right to receive, upon exercise, Common Shares (or, in certain circumstances, Common Stock Equivalents (as such term is defined in the Rights Agreement)) having a value equal to two (2) times the exercise price of the Right. Upon the occurrence of any event described in the preceding sentence, any Rights beneficially owned by (i) an Acquiring Person or an Associate or Affiliate (as such terms are defined in the Rights Agreement) of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, agreement, arrangement or understanding which has as a primary purpose or effect the avoidance of the Rights Agreement, shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of the Rights Agreement or otherwise.

At any time after the occurrence of the event described in the first sentence of the preceding paragraph (and prior to the acquisition by any person or group of affiliated or associated persons of 50% or more of the outstanding Common Shares), the Board of Directors of the Company may exchange the Rights (except Rights which previously have been voided as described above), in whole, but not in part, at an exchange ratio of one Common Share (or, in certain circumstances, one Common Stock Equivalent) per Right.

In the event that, at any time after any person or group of affiliated or associated persons becomes an Acquiring Person, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving corporation, (ii) the Company engages in a merger or other business combination transaction with another person in which the Company is the surviving corporation, but in which its Common Shares are changed or exchanged, or (iii) more than 50% of the Company’s assets or earning power is sold or transferred, the Rights Agreement provides that proper provision shall be made so that each holder of a Right (except Rights which previously have been voided as described above) shall thereafter have the right to receive, upon the exercise thereof at the then current exercise price of the Right, common stock of the acquiring company having a value equal to two (2) times the exercise price of the Right.

The Purchase Price payable, and the number of Units of Preferred Shares or other securities issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights, options or warrants to subscribe for Preferred Shares or convertible securities at less than the current market price of the Preferred Shares, or (iii) upon the distribution to holders of the Preferred Shares of evidences of indebtedness, stock (other than a dividend payable in Preferred Shares), assets or cash (excluding regular quarterly cash dividends) or of subscription

rights, options or warrants (other than those referred to above). Such terms are also subject to adjustment in the event of a stock split of the Common Shares or a stock dividend on the Common Shares payable in Common Shares or subdivisions, consolidations or combinations of the Common Shares occurring, in any such case, prior to the Distribution Date.

With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price. No fractional Units will be issued and, in lieu thereof, an adjustment in cash will be made as provided in the Rights Agreement.

At any time prior to such time as any person or group of affiliated or associated persons becomes an Acquiring Person, the Board of Directors may redeem the Rights in whole, but not in part, at a price of $.01 per Right, subject to adjustment (the “Redemption Price”). Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights (or at such later time as the Board of Directors may establish for the effectiveness of such redemption), the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.

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

The terms of the Rights may be amended by the Company and the Rights Agent, provided that following the Share Acquisition Date the amendment does not materially adversely affect the interests of holders of Rights (other than an Acquiring Person) and provided that no amendment shall be made which decreases the Redemption Price.

A copy of the Rights Agreement is being filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A. A copy of the Rights Agreement will be available free of charge from the Company. This summary description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which is incorporated herein by reference.

Rights Agreement Dated as of September 25, 2003
