RIGHTS AGREEMENT

RIGHTS AGREEMENT, dated as of October 30, 2008 (the “Agreement”), between Sourcefire, Inc., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Co., a banking organization organized under the laws of the State of New York, as rights agent (the “Rights Agent”).

WHEREAS, effective October 29, 2008 (the “Rights Dividend Declaration Date”), the Board of Directors of the Company (the “Board of Directors”) (i) authorized and declared a dividend of one right (“Right”) for each share of Common Stock, par value $.001 per share, of the Company (the “Company Common Stock”) outstanding at the Close of Business on November 14, 2008 (the “Record Date”), and (ii) authorized the issuance of one Right (as such number may hereinafter be adjusted pursuant hereto) for each share of Company Common Stock issued between the Record Date and the earlier of the Distribution Date and the Expiration Date and, in certain circumstances, for each share of Company Common Stock issued after the Distribution Date but before the Expiration Date; and

WHEREAS, each Right initially represents the right to purchase, upon the terms and subject to the conditions hereinafter set forth, one Unit of Series A Junior Participating Preferred Stock;

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

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

(a) “Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of 15% or more of the shares of Company Common Stock then outstanding. Notwithstanding the foregoing:

(i) an “Acquiring Person” shall not include:

(A) the Company;

(B) any Subsidiary of the Company;

(D) any trustee or fiduciary with respect to such employee benefit plan acting in such capacity or a trustee or fiduciary holding shares of Company Common Stock for the purpose of funding any such plan;

(E) any Person if:

(1) the Board of Directors determines in good faith that such Person who would otherwise be an “Acquiring Person” became such inadvertently (including, without limitation, because (x) such Person was

unaware that it beneficially owned a percentage of Company Common Stock that would otherwise cause such Person to be an “Acquiring Person” or (y) such Person was aware of the extent of its Beneficial Ownership of Company Common Stock but had no actual knowledge of the consequences of such Beneficial Ownership under this Agreement) and without any intention of changing or influencing control of the Company;

(2) such Person does not become the Beneficial Owner of any additional shares of Company Common Stock after such Person becomes aware that such Person would be an Acquiring Person (but for the operation of this clause (E)); and

(3) such Person as promptly as practicable (as determined in good faith by the Board of Directors) divested or divests itself of Beneficial Ownership of a sufficient number of shares of Company Common Stock so that such Person would no longer be an “Acquiring Person;”

(F) any Person who becomes the Beneficial Owner of 15% or more of the then-outstanding shares of Company Common Stock as a result of the acquisition of shares of Company Common Stock directly from the Company in one or more transactions approved by the Board of Directors,

and

(ii) no Person shall be deemed an “Acquiring Person” as a result of the acquisition of shares of Company Common Stock by the Company which, by reducing the number of shares of Company Common Stock outstanding, increases the proportional number of shares beneficially owned by such Person; provided, however, that if (x) a Person would become an Acquiring Person (but for the operation of this subclause (ii)) as a result of the acquisition of shares of Company Common Stock by the Company and (y) after such share acquisition by the Company, such Person becomes the Beneficial Owner of any additional shares of Company Common Stock (other than pursuant to the grant or exercise of an option under a Company stock option plan or pursuant to a dividend or distribution paid or made by the Company on the outstanding shares of Company Common Stock or pursuant to a split or subdivision of the Company Common Stock), then such Person shall be deemed an Acquiring Person unless, upon becoming the Beneficial Owner of such additional shares, such Person is the Beneficial Owner of less than 15% of the outstanding shares of Company Common Stock.

Each Person identified in subclauses (A), (B), (C) and (D) of this Section (1)(a) is individually an “Exempt Person” and collectively “Exempt Persons.”

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

(c) A Person shall be deemed the “Beneficial Owner” of, and shall be deemed to have “Beneficial Ownership” of and to “beneficially own,” any securities:

(i) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to vote or dispose of or has “beneficial ownership” of under Rule 13d-3 of the General Rules and Regulations under the Exchange Act (the “Exchange Act Regulations”) as in effect on the date hereof, including pursuant to any agreement, arrangement or understanding (whether or not in writing); provided, however, that a Person shall not be deemed the “Beneficial Owner” of, to have “Beneficial Ownership” of or to “beneficially own,” any securities under this subparagraph (i) as a result of an agreement, arrangement or understanding to vote such securities if such agreement, arrangement or understanding (A) arises solely from a revocable proxy or consent given in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable provisions of the Exchange Act and the Exchange Act Regulations, and (B) is not reportable by such Person on Schedule 13D under the Exchange Act (or any comparable or successor report);

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

(iii) 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 or upon the satisfaction of conditions) pursuant to any agreement, arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, rights, warrants or options, or otherwise; or

(iv) in respect of which such Person or any of such Person’s Affiliates or Associates has a Synthetic Long Position that has been disclosed in a filing by such Person or any of such Person’s Affiliates or Associates with the Securities and Exchange Commission pursuant to Regulation 13D-G or Regulation 14D under the Exchange Act in respect of which Company Common Stock is the “subject security” (as such term is used in such Regulations);

provided, however, that under this paragraph (c) a Person shall not be deemed the “Beneficial Owner” of, to have “Beneficial Ownership” of, or to “beneficially own,” any securities

(A) tendered pursuant to a tender or exchange offer made in accordance with Exchange Act Regulations by such Person or any of such

Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange,

(B) that may be issued upon exercise of Rights at any time prior to the occurrence of a Triggering Event, or

(C) that may be issued upon exercise of Rights from and after the occurrence of a Triggering Event, which Rights were acquired by such Person or any of such Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3(c) or Section 22 hereof (the “Original Rights”) or pursuant to Section 11(i) hereof in connection with an adjustment made with respect to any Original Rights; and

further provided, however, that:

(x) nothing in this paragraph (c) shall cause a Person engaged in business as an underwriter of securities to be the “Beneficial Owner” of, to have “Beneficial Ownership” of, or to “beneficially own,” any securities acquired through such Person’s participation in good faith in a firm commitment underwriting until the expiration of forty days after the date of such acquisition,

(y) no decision reached, or action taken, by the Board of Directors or any committee thereof shall cause any Person (or any Affiliate or Associate of such Person) who is a member of the Board of Directors or such committee to be deemed, for the purposes of this Agreement, to be a Beneficial Owner of any securities beneficially owned by any other Person (or any Affiliate or Associate of such Person) who is a member of the Board of Directors or any committee thereof solely by reason of such membership of the Board of Directors or any committee thereof or participation in the decisions or actions thereof on the part of either or both of such Persons, and

(z) no Person who is an officer, director or employee of an Exempt Person shall be deemed, solely by reason of such Person’s status or authority as such, to be the “Beneficial Owner” of, to have “Beneficial Ownership” of, or to “beneficially own” any securities that are “beneficially owned” (as defined in this paragraph (c)), including, without limitation, in a fiduciary capacity, by an Exempt Person or by any other such officer, director or employee of an Exempt Person.

(d) “Business Day” shall mean any day other than a Saturday, Sunday or a day on which banking institutions in New York, New York 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 Stock” of any Person other than the Company shall mean the capital stock of such Person with the greatest voting power, or, if such Person shall have no

capital stock, the equity securities or other equity interest having power to control or direct the management of such Person.

(g) “Company” has the meaning given it in the first paragraph of this Agreement, and also means a Principal Party to the extent provided in Section 13(a).

(h) “Person” shall mean any individual, partnership, firm, limited liability company, corporation, association, trust, unincorporated organization or other entity, as well as any syndicate or group deemed to be a person under Section 14(d)(2) of the Exchange Act as in effect on the date hereof.

(i) “Preferred Stock” shall mean the Series A Junior Participating Preferred Stock, par value $.001 per share, of the Company having the voting powers, designation, preferences and relative, participating, optional or other special rights and qualifications, limitations and restrictions described in the Certificate of Designation set forth as Exhibit C hereto and as amended from time to time.

(j) “Stock Acquisition Date” shall mean the first date of public announcement (including, without limitation, the filing of any report, or any amendment to any report, pursuant to Section 13(d) of the Exchange Act (or any comparable or successor report)) by the Company or an Acquiring Person that an Acquiring Person has become such; provided, however, that if such Person is determined not to have become an Acquiring Person pursuant to Section 1(a) hereof, then no Stock Acquisition Date shall be deemed to have occurred.

(k) “Subsidiary” shall mean, with reference to any Person, any other Person of which an amount of voting securities or equity interests sufficient to elect at least a majority of the directors or equivalent governing body of such other Person is beneficially owned, directly or indirectly, by such Person, or any other Person otherwise controlled by such first-mentioned Person.

(l) “Synthetic Long Position” shall mean any option, warrant, convertible security, stock appreciation right or other contractual right, whether or not presently exercisable, which has an exercise or conversion privilege or a settlement payment or mechanism at a price related to Company Common Stock or a value determined in whole or part with reference to, or derived in whole or in part from, the market price or value of Company Common Stock, whether or not such right is subject to settlement in whole or in part in Company Common Stock, and which increases in value as the value of Company Common Stock increases or which provides to the holder of such right an opportunity, directly or indirectly, to profit or share in any profit derived from any increase in the value of Company Common Stock, but shall not include:

(i) rights of a pledgee under a bona fide pledge of Company Common Stock;

(ii) rights of all holders of Company Common Stock to receive Company Common Stock pro rata, or obligations to dispose of Company Common Stock, as a result of a merger, exchange offer, or consolidation involving the Company;

Section 2. Appointment of Rights Agent. The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-rights agents as it may deem necessary or desirable. The Rights Agent shall have no duty to supervise, and in no event shall be liable for, the acts or omissions of any such co-rights agent.

Section 3. Issuance of Rights Certificates.

(a) Until the earlier of (i) the Close of Business on the tenth Business Day after the Stock Acquisition Date (or, if the tenth Business Day after the Stock Acquisition Date occurs before the Record Date, the Close of Business on the Record Date), and (ii) the Close of Business on the tenth Business Day (or such later date as may be determined by action of the Board of Directors) after the date that a tender or exchange offer by any Person (other than an Exempt Person) is first published or sent or given within the meaning of Rule 14d-4(a) of the Exchange Act Regulations or any successor rule, if upon consummation thereof such Person would be an Acquiring Person (including, in the case of both clause (i) and (ii), any such date which is after the date of this Agreement and prior to the issuance of the Rights) (the earlier of (i) and (ii) above being the “Distribution Date”):

(x) the Rights will be evidenced (subject to the provisions of paragraph (b) of this Section 3) by the certificates for shares of Company Common Stock

registered in the names of the holders of shares of Company Common Stock as of and subsequent to the Record Date (which certificates for shares of Company Common Stock shall be deemed also 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 shares of Company Common Stock including a transfer to the Company;

provided, however, that if a tender or exchange offer is terminated prior to the occurrence of a Distribution Date, then no Distribution Date shall occur as a result of such tender or exchange offer. 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 shares of Company Common Stock as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, one or more rights certificates, in substantially the form of Exhibit A hereto (the “Rights Certificates”), evidencing one Right for each share of Company Common Stock so held, subject to adjustment as provided herein.

In the event that an adjustment in the number of Rights per share of Company Common Stock has been made pursuant to Section 11(p) hereof, at the time of distribution of the Rights Certificates, the Company may make the necessary and appropriate rounding adjustments (in accordance with Section 14(a) hereof) so that Rights Certificates representing only whole numbers of Rights are distributed and cash is paid in lieu of any fractional Rights. As of and after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates.

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

(c) Rights shall, without any further action, be issued in respect of all shares of Company Common Stock which are issued (including any shares of Company Common Stock held in treasury) after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date. In addition, Rights shall be issued with respect to all shares of Company Common Stock described in the second sentence of Section 22 hereof, subject to the provisions thereof. Certificates representing such shares of Company Common Stock issued after the Record Date 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 Sourcefire, Inc. (the “Company”) and Continental

Stock Transfer & Trust Co. (the “Rights Agent”) dated as of October 30, 2008, as amended from time to time (the “Rights Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the office of the Rights Agent. 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, as in effect on the date of mailing, without charge promptly after receipt of a written request therefor. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

With respect to certificates representing shares of Company Common Stock that bear the foregoing legend, until the earlier of the Distribution Date and the Expiration Date, the Rights associated with the shares of Company Common Stock represented by such certificates shall be evidenced by such certificates alone and registered holders of the shares of Company Common Stock shall also be the registered holders of the associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the shares of Company Common Stock represented by such certificates.

(d) In the event that the Company purchases or acquires any shares of Company Common Stock after the Record Date but prior to the Distribution Date, any Rights associated with such shares of Company Common Stock shall be deemed canceled and returned so that the Company shall not be entitled to exercise any Rights associated with the shares of Company Common Stock that are no longer outstanding.

(e) Notwithstanding anything to the contrary contained herein, shares of Company Common Stock and Rights (and any securities issuable on their exercise) may be issued and transferred by book-entry and not represented by physical certificates. Where shares of Company Common Stock and Rights (and any securities issuable on their exercise) are held in uncertificated form, the Company and the Rights Agent shall cooperate in all respects to give effect to the intent of the provisions contained herein.

Section 4. Form of Rights Certificates.

(a) The Rights Certificates (and the forms of election to purchase and of assignment and the certificates to be printed on the reverse thereof) shall each be substantially in the form set forth in Exhibit A hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or any rule or regulation thereunder or with any rule or regulation of any stock exchange or automated quotation system on which the Rights may from time to time be listed or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Record

Date (or in the case of Rights issued with respect to Common Stock issued by the Company after the Record Date, as of the date of issuance of such Common Stock) and on their face shall entitle the holders thereof to purchase such number of Units of Preferred Stock as shall be set forth therein at the price set forth therein, provided, however, that the amount and type of securities, cash or other assets that may be acquired upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein.

(b) Any Rights Certificate that represents Rights which are null and void pursuant to Section 7(e) of this Agreement and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (to the extent feasible) the following legend:

The Rights represented by this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). Accordingly, this Rights Certificate and the Rights represented hereby are null and void.

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

Section 5. Countersignature and Registration.

(a) Any Rights Certificates shall be executed on behalf of the Company by its Chairman, its Chief Executive Officer, its President or one of its Vice Presidents and shall be attested by its Secretary, Treasurer or one of its Assistant Secretaries and shall have affixed thereto the Company’s seal (if any) or a facsimile thereof. The signature of any of these officers on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of the individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature of such Rights Certificates or did not hold such offices at the date of such Rights Certificates. No Rights Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose unless there appears on such Rights Certificate a countersignature duly executed by the Rights Agent by manual or facsimile signature of an authorized signatory, and such countersignature upon any Rights Certificate shall be conclusive evidence, and the only evidence, that such Rights Certificate has been duly countersigned as required hereunder.

(b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its office designated for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the name and address of each holder of the Rights Certificates, the number of Rights evidenced on its face by each Rights Certificate and the date of each Rights Certificate.

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

(a) Subject to the provisions of Sections 4, 7(e) and 14 hereof, at any time after the Close of Business on the Distribution Date, and at or prior to the Close of Business on

the Expiration Date, any Rights Certificate or Certificates may be transferred, split up, combined or exchanged for another Rights Certificate or Certificates, entitling the registered holder to purchase a like number of Units of Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) as the Rights Certificate or Certificates surrendered then entitled such holder (or former holder, in the case of a transfer) to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Certificates to be transferred, split up, combined or exchanged at the office 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 Rights Certificate until the registered holder shall have completed and executed the certificate set forth in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) of the Rights represented by such Rights Certificate or Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent shall, subject to the provisions of Section 4, Section 7(e), Section 14 and Section 24 hereof, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights 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 Rights Certificates.

(b) Subject to Section 7(e) hereof, if a Rights Certificate shall be mutilated, lost, stolen or destroyed, upon request by the registered holder of the Rights represented thereby and upon payment to the Company and the Rights Agent of all reasonable expenses incident thereto, there shall be issued, in exchange for and upon cancellation of the mutilated Rights Certificate, or in substitution for the lost, stolen or destroyed Rights Certificate, a new Rights Certificate, in substantially the form of the prior Rights Certificate, of like tenor and representing the equivalent number of Rights, but, in the case of loss, theft or destruction, only upon receipt of evidence satisfactory to the Company and the Rights Agent of such loss, theft or destruction of such Rights Certificate and, if requested by the Company or the Rights Agent, indemnity also satisfactory to it.

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

(a) Prior to the earlier of (i) the Close of Business on the tenth anniversary hereof (the “Final Expiration Date”), (ii) the time at which the Rights are redeemed as provided in Section 23 hereof, and (iii) the time at which the Rights are exchanged as provided in Section 24 hereof, at which time the Rights are deemed terminated (the earlier of (i), (ii), and (iii) being the “Expiration Date”), the registered holder of any Rights Certificate may, subject to the other provisions hereof, including without limitation Sections 7(e), 7(f), 9(c), 11(a) and 23 hereof, exercise the Rights evidenced thereby, in whole or in part, at any time after the Distribution Date upon surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price for the number of Units of Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) for which such surrendered Rights are then exercisable.

(b) The purchase price for each one one-hundredth of a share (each such one one-hundredth of a share being a “Unit”) of Preferred Stock upon exercise of Rights shall be $30.00, subject to adjustment from time to time as provided in Sections 11 and 13(a) hereof (such purchase price, as so adjusted, being the “Purchase Price”), and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below.

(c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase and the certificate duly executed, accompanied by payment, with respect to each Right so exercised, of the Purchase Price for the Units of Preferred Stock (or, following a Triggering Event, other securities, cash or other assets, as the case may be) to be purchased thereby as set forth below and an amount equal to any applicable transfer tax or evidence satisfactory to the Company of payment of such tax, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly:

(i) (A) requisition from any transfer agent of the Preferred Stock (or make available, if the Rights Agent is the transfer agent for the Preferred Stock) a certificate or certificates for the number of Units of Preferred Stock to be purchased, and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the total number of Units of Preferred Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the depositary agent depositary receipts representing interests in such number of Units of Preferred Stock as are to be purchased (in which case certificates for the Units of Preferred Stock represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company hereby directs the depositary agent to comply with such request,

(ii) 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 Rights Certificate, registered in such name or names as may be designated by such holder,

(iii) requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14 hereof, and

(iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate.

In the event that the Company is obligated to issue Company Common Stock or other securities of the Company, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such Company Common Stock, other securities, cash and/or other property are available for distribution by the Rights Agent, if and when appropriate. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii) hereof) shall be made by certified or bank check or money order payable to the order of the Rights Agent.

(d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate evidencing the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the

registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Sections 6 and 14 hereof.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of any Section 11(a)(ii) Event, any Rights beneficially owned by:

(i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person,

(ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) which becomes a transferee after the Acquiring Person becomes such, or

(iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) which becomes a transferee prior to or concurrently with the Acquiring Person becoming such and which receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person (or any such Associate or Affiliate) to holders of equity interests in such Acquiring Person (or any such Associate or Affiliate) or to any Person with whom the Acquiring Person (or such Associate or Affiliate) has any continuing agreement, arrangement or understanding regarding the transferred Rights, shares of Company Common Stock or the Company or (B) a transfer which the Board of Directors has determined to be part of a plan, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e),

shall be 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. The Company shall use all reasonable efforts to ensure that the provisions of this Section 7(e) and Section 4(b) hereof are complied with, but shall have no liability to any holder of Rights or any other Person as a result of the Company’s failure to make or delay in making any determinations with respect to an Acquiring Person or its Affiliates or Associates or any transferee or any of them hereunder.

(f) Notwithstanding anything in this Agreement or any Rights Certificate 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 exercise by such registered holder unless such registered holder shall have (i) completed and executed the certificate following the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise, (ii) not indicated an affirmative response to clause 1 or 2 thereof, and (iii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) of the Rights represented by such Rights Certificate or Affiliates or Associates thereof as the Company shall reasonably request.

Section 8. Cancellation and Destruction of Rights Certificates. All Rights Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or 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 Rights Certificates shall be issued in lieu thereof except as expressly permitted by this

Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any Rights Certificates acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. Reservation and Availability of Capital Stock.

(a) The Company shall, at all times prior to the occurrence of a Section 11(a)(ii) Event, cause to be reserved and kept available, out of its authorized and unissued shares of preferred stock or its authorized and issued shares of preferred stock held in its treasury, and, after the occurrence of a Section 11(a)(ii) Event, to the extent reasonably practical, cause to be reserved and kept available, out of its authorized but unissued shares of preferred stock, Company Common Stock and/or other securities or its authorized and issued shares held in its treasury, the number of shares of Preferred Stock (and, following the occurrence of a Section 11(a)(ii) Event, Company Common Stock and/or other securities) that, as provided in this Agreement, will be sufficient to permit the exercise in full of all outstanding Rights. Upon the occurrence of any events resulting in an increase in the aggregate number of shares of Preferred Stock (or other equity securities of the Company) issuable upon exercise of all outstanding Rights above the number then reserved, the Company shall make appropriate increases in the number of shares so reserved to the extent reasonably practicable.

(b) If the shares of Preferred Stock (and, following the occurrence of a Section 11(a)(ii) Event, Company Common Stock and/or other securities) to be issued and delivered upon the exercise of the Rights may be listed on any national securities exchange or automated quotation system, the Company shall use its best efforts to cause, from and after the time that the Rights become exercisable, all securities reserved for such issuance to be listed on such exchange or quotation system upon official notice of issuance upon such exercise.

(i) as soon as practicable following the earliest date after the occurrence of a Section 11(a)(ii) Event and a determination by the Company of the consideration to be delivered by the Company upon exercise of the Rights (including in accordance with Section 11(a)(iii) hereof) or, if so required by law, as soon as practicable following the Distribution Date (such date being the “Registration Date”), to file a registration statement on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the securities that may be acquired upon exercise of the Rights (the “Registration Statement”),

(ii) to cause the Registration Statement to become effective as soon as practicable after such filing,

(iii) to cause the Registration Statement to continue to be effective (and to include a prospectus complying with the requirements of the Securities Act) until the

earlier of (A) the date as of which the Rights are no longer exercisable for the securities covered by the Registration Statement, and (B) the Expiration Date, and

(iv) to take as soon as practicable following the Registration Date such action as may be required to ensure that any acquisition of securities upon exercise of the Rights complies with any applicable state securities or “blue sky” laws.

The Company may temporarily suspend, for a period of time not to exceed one hundred twenty (120) days after the Registration Date, 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. 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 a registration statement shall not have been declared effective.

(d) The Company shall take all such action as may be necessary to ensure that all shares of Preferred Stock (and, following the occurrence of a Triggering Event, any other securities that may be delivered upon exercise of Rights) shall be, at the time of delivery of the certificates or depositary receipts for such securities (subject to payment of the Purchase Price), duly and validly authorized and issued and fully paid and nonassessable.

(e) The Company shall pay any documentary, stamp or other tax or charge imposed in connection with the issuance or delivery of the Rights Certificates or of any Preferred Stock (or any other securities or assets, as the case may be) upon the exercise of Rights; provided, however, the Company shall not be required to pay any such tax or charge imposed in connection with the issuance or delivery of Units of Preferred Stock, or any certificates or depositary receipts for such Units of Preferred Stock (or, following the occurrence of a Triggering Event, any other securities, cash or assets, as the case may be) to any Person other than the registered holder of the Rights Certificates evidencing the Rights surrendered for exercise. The Company shall not be required to issue or deliver any certificates or depositary receipts for Units of Preferred Stock (or, following the occurrence of a Triggering Event, any other securities, cash or assets, as the case may be) to, or in a name other than that of, the registered holder upon the exercise of any Rights until any such tax or charge shall have been paid (any such tax or charge being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax or charge is due.

Section 10. Preferred Stock Record Date. Each Person in whose name any certificate or depositary receipt for Units of Preferred Stock (or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Units of Preferred Stock (or other securities) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and any applicable taxes or charges) was made; provided, however, that if the date of such surrender and payment is a date upon which the Preferred Stock (or other securities, as the case may be) transfer books of the Company are

closed, such Person shall be deemed to have become the record holder of such securities on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Stock (or other securities) transfer books of the Company are open; further provided, however, that if delivery of Units of Preferred Stock (or other securities, as the case may be) is delayed pursuant to Section 9(c) hereof, such Persons shall be deemed to have become the record holders of such Units of Preferred Stock (or other securities) only when such Units (or other securities) first become deliverable. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate shall not be entitled to any rights of a stockholder of the Company with respect to securities for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

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

(a) (i) In the event the Company shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (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 for herein, including this Section 11(a) and 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 shares of Preferred Stock or other capital stock, as the case may be, issuable on such date upon exercise of the Rights, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect, the aggregate number and kind of shares of Preferred Stock or other capital stock, as the case may be, which, if such Right had been exercised immediately prior to such date and at a time when the transfer books of the Company were still open, such holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

(ii) In the event any Person, alone or together with its Affiliates and Associates, shall become an Acquiring Person, other than pursuant to any transaction set forth in Section 13(a) hereof, then, immediately upon the occurrence of such event (a “Section 11(a)(ii) Event”), each holder of a Right (except as otherwise provided herein, including Section 7(e) hereof) shall thereafter have the right to receive, upon exercise of such Right at the then-current Purchase Price in accordance with the terms of this Agreement, in lieu of the number of Units of Preferred Stock for which a Right was

exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event (whether or not such Right was then exercisable), such number of Units of Preferred Stock as shall equal the result obtained by:

(A) multiplying the then-current Purchase Price by the number of Units of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event (whether or not such Right was then exercisable) (such product thereafter being, for all purposes of this Agreement, other than Section 13 hereof, the “Purchase Price”), and

(B) dividing that product by 50% of the current market price (determined pursuant to Section 11(d) hereof) per Unit of Preferred Stock on the date of such first occurrence

(such Units of Preferred Stock being the “Adjustment Shares”); provided, however, that the Purchase Price and the number of Units of Preferred Stock so receivable upon exercise of a Right shall, following the Section 11(a)(ii) Event, be subject to further adjustment as appropriate in accordance with this Section 11. From and after the occurrence of a Section 13(a) Event, any Rights that have not theretofore been exercised pursuant to this Section 11(a)(ii) shall thereafter be exercisable only in connection with Section 13 and not pursuant to this Section 11(a)(ii).

(iii) The Company, by the vote of the Board of Directors, may at its option substitute for a Unit of Preferred Stock issuable upon the exercise of Rights in accordance with the foregoing subparagraph (ii), shares of Company Common Stock or fractions thereof having a current market price (as determined by Section 11(d) hereof) equal to the current market price of a Unit of Preferred Stock on the date of the Section 11(a)(ii) Event. In the event that the number of shares of Preferred Stock (or, if the Company shall have determined to substitute shares of Company Common Stock for Units of Preferred Stock pursuant to the preceding sentence, Company Common Stock) which are authorized by the Company’s Certificate of Incorporation, but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights, is not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall, to the extent permitted by applicable law:

(A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of a Right (the “Current Value”) over (2) the Purchase Price (such excess being the “Spread”), and

(B) with respect to each Right (other than Rights which have become void pursuant to Section 7(e)), make adequate provision to substitute, in whole or in part, for such Adjustment Shares, upon exercise of a Right and payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) shares of Company Common Stock or other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock (such other shares being “common stock equivalents”)), (4) debt securities

of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate value which, when added to the value of the Units of Preferred Stock actually issued upon exercise of such Right, shall have an aggregate value equal to the Current Value (less the amount of any reduction in such Purchase Price), where such aggregate value has been determined by the Board of Directors, after receiving advice from a nationally recognized investment banking firm;

provided, however, that if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty days following the later of (x) the first occurrence of a Section 11(a)(ii) Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a) expires (such thirty day period, as it may be extended hereunder, being referred to herein as the “Substitution Period,” and the later of (x) and (y) being referred to herein as the “Section 11(a)(iii) Trigger Date”), then, subject to Section 24 hereof, the Company shall be obligated (to the extent permitted by applicable law) to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, Units of Preferred Stock (to the extent available) and then, if necessary, shares (or fractions of shares, at the discretion of the Board of Directors) of Company Common Stock and cash, or a combination thereof, which Units of Preferred Stock, shares (or fractions of shares) of Company Common Stock and/or cash shall have an aggregate value equal to the Spread. If the Board of Directors determines in good faith that it is likely that sufficient additional shares of Preferred Stock or Company Common Stock could be authorized for issuance upon exercise in full of the Rights, then the Substitution Period may be extended to the extent necessary, but not more than ninety days after the Section 11(a)(iii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares.

To the extent that the Company determines that some action need be taken pursuant to the second and/or third sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such second sentence and to determine the value thereof. If any such suspension occurs, 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 the time such suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of a Unit of Preferred Stock or share of Company Common Stock shall be the current market price (as determined pursuant to Section 11(d) hereof) per Unit of Preferred Stock or share of Company Common Stock, as the case may be, on the Section 11(a)(iii) Trigger Date and the value of any common stock equivalent shall be deemed to have the same value as a Unit of Preferred Stock on such date.

(b) In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred Stock entitling them to subscribe for or purchase (for a period expiring within forty-five calendar days after such record date) shares of Preferred Stock (or shares having substantially the same rights, privileges and preferences as shares of

Preferred Stock (“Equivalent Preferred Stock”)) or securities convertible into Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred Stock or per share of Equivalent Preferred Stock (or having a conversion price per share, if a security convertible into Preferred Stock or Equivalent Preferred Stock) less than the current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying:

(i) the Purchase Price in effect immediately prior to such record date, by

(ii) a fraction, (A) the numerator of which shall be the sum of the number of shares of Preferred Stock outstanding on such record date, plus the number of shares of Preferred Stock which the aggregate offering price of the total number of shares of Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price, and (B) the denominator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of additional shares of Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible).

In case such subscription price may be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. Shares of Preferred Stock owned by or held for the account of the Company or any Subsidiary shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, the 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 shares of Preferred Stock (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 periodic cash dividend paid out of funds legally available therefor), assets (other than a dividend payable in shares of Preferred Stock, but including any dividend payable in stock other than Preferred Stock) or subscription rights, options or warrants (excluding those referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying:

(i) the Purchase Price in effect immediately prior to such record date, by

(ii) a fraction, (A) the numerator of which shall be the current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights

Agent and shall be conclusive for all purposes) of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights, options or warrants distributable in respect of a share of Preferred Stock and (B) the denominator of which shall be such current market price per share of Preferred Stock.

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 be adjusted to be the Purchase Price which would have been in effect if such record date had not been fixed.

(d) (i) For the purpose of any computation hereunder, the “current market price” per share of Company Common Stock or Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such shares for the thirty consecutive Trading Days immediately prior to such date; provided, however, if prior to the expiration of such requisite thirty Trading Day period the issuer announces either (A) a dividend or distribution on such shares payable in such shares or securities convertible into such shares (other than the Rights), or (B) any subdivision, combination or reclassification of such shares, and the ex-dividend date for such dividend or distribution or the record date for such subdivision, combination or reclassification, as the case may be, shall not have occurred prior to the commencement of the requisite thirty Trading Day period, then, and in each such case, the “current market price” shall be properly adjusted to take into account such event. The closing price for each day shall be:

(x) the last sale price, regular way, or, in the 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 on the principal national securities exchange on which such shares are listed or admitted to trading, or

(y) if such shares are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the Nasdaq Stock Market (“Nasdaq”) or such other system then in use, or

(z) if on any such date such 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 such shares selected by the Board of Directors.

If on any such date no market maker is making a market in such shares, or if such shares are not publicly held or 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, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. The term “Trading Day” shall mean, if such shares are listed or admitted to trading on any national securities exchange, a day on which the principal national securities exchange on which such shares are listed or admitted to trading is open

for the transaction of business or, if such shares are not so listed or admitted, a Business Day.

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

(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 the Purchase 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 one one-thousandth of a share of Company Common Stock or Common Stock or other share or one one hundred-thousandth of a share of Preferred Stock, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which mandates such adjustment and (ii) the Expiration Date.

(f) If, as a result of an adjustment made pursuant to Section 11(a)(ii) or 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Preferred Stock, thereafter the number of such other shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Sections 11(a), (b), (c), (d), (e), (g), (h), (i), (j), (k), (l) and (m), and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares.

(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 Units of Preferred Stock (or other securities or amount of cash or combination thereof) that may be acquired from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in 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 Units of Preferred Stock (calculated to the nearest one ten-thousandth of a Unit) obtained by (i) multiplying (x) the number of Units of Preferred Stock 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 lieu of any adjustment in the number of Units of Preferred Stock that may be acquired upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of Units of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing (x) the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the (y) 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 Rights Certificates have been issued, shall be at least ten days later than the date of such public announcement. If Rights 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 Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 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 Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates to be so 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 Rights 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 Units of Preferred Stock issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price per Unit and the number of Units of Preferred Stock which were expressed in the initial Rights Certificates issued hereunder.

(k) Before taking any action that would cause an adjustment reducing the Purchase Price below the par or stated value, if any, of the number of Units of Preferred Stock or other shares of capital stock issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the

Company may validly and legally issue such fully paid and nonassessable number of Units of Preferred Stock or other shares at such adjusted Purchase Price.

(l) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date of that number of Units of Preferred Stock and shares of other capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of Units of Preferred Stock and shares of 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 xxxx or other appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) or securities 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 in their good faith judgment the Board of Directors shall determine to be advisable in order that any (i) consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares of Preferred Stock at less than the current market price, (iii) issuance wholly for cash of shares of Preferred Stock or securities which by their terms are convertible into or exchangeable for shares of Preferred Stock, (iv) stock dividends or (v) issuance of rights, options or warrants referred to in this Section 11, hereafter made by the Company to holders of its Preferred Stock, shall not be taxable to such holders or shall reduce the taxes payable by such holders.

(n) The Company shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a wholly owned Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a wholly owned Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of transactions, assets, cash flow or earning power aggregating more than 50% of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its wholly owned Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if:

(x) at the time of or immediately after such consolidation, merger, sale or transfer there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights, or

(y) prior to, simultaneously with or immediately after such consolidation, merger, sale or transfer, the Person which constitutes, or would constitute, the “Principal Party” for purposes of Section 13(a) hereof shall have distributed or otherwise transferred to its stockholders or other persons holding an equity interest in such Person Rights previously owned by such Person or any of its Affiliates and Associates.

(o) After the Distribution Date, the Company shall not, except as permitted by Section 23, Section 24 or Section 27 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

(p) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a dividend on the outstanding shares of Company Common Stock payable in shares of Company Common Stock, (ii) subdivide the outstanding shares of Company Common Stock or (iii) combine the outstanding shares of Company Common Stock into a smaller number of shares, the number of Rights associated with each share of Company Common Stock then outstanding, or issued or delivered thereafter prior to the Distribution Date or in accordance with Section 22 hereof, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Company Common Stock following any such event shall equal the result obtained by multiplying:

(x) the number of Rights associated with each share of Company Common Stock immediately prior to such event, by

(y) a fraction, (A) the numerator of which shall be the total number of shares of Company Common Stock outstanding immediately prior to the occurrence of the event and (B) the denominator of which shall be the total number of shares of Company Common Stock outstanding immediately following the occurrence of such event.

Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Section 11 or Section 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 Stock and the Company Common Stock, a copy of such certificate, and (c) mail a brief summary thereof to each holder of a Rights Certificate (or, if prior to the Distribution Date, to each holder of a certificate representing shares of Company Common Stock) in accordance with Section 26 hereof. Notwithstanding the foregoing sentence, the failure of the Company to make such certification or give such notice shall not affect the validity of such adjustment or the force or effect of the requirement for such adjustment. 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, Cash Flow or Earning Power.

(a) In the event that, following the first occurrence of a Section 11(a)(ii) Event, directly or indirectly, either:

(x) the Company shall consolidate with, or merge with and into, any other Person (other than a wholly owned Subsidiary of the Company in a transaction

which complies with Section 11(o) hereof), and the Company shall not be the continuing or surviving corporation of such consolidation or merger,

(y) any Person (other than a wholly owned Subsidiary of the Company in a transaction which complies with Section 11(o) hereof) shall consolidate with, or merge with or 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 shares of Company Common Stock shall be changed into or exchanged for stock or other securities of the Company or any other Person or cash or any other property, or

(z) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer) to any Person or Persons (other than the Company or any of its wholly owned Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), in one or more transactions, assets, cash flow or earning power aggregating 50% or more of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole)

(any such event being a “Section 13 Event”), then, and in each such case, proper provision shall be made so that:

(i) each holder of a Right (other than Rights which have become void as provided in Section 7(e) hereof) shall thereafter have the right to receive, upon the exercise thereof at the then-current Purchase Price, in accordance with this Agreement and in lieu of Units of Preferred Stock or shares of Company Common Stock, such number of validly authorized and issued, fully paid, nonassessable and freely tradeable shares of Common Stock of the Principal Party, which shares shall not be subject to any liens, encumbrances, rights of call or first refusal, transfer restrictions or other adverse claims, as shall be equal to the result obtained by:

(A) multiplying (x) the then-current Purchase Price by (y) the number of Units of Preferred Stock for which a Right is exercisable immediately prior to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section 13 Event, multiplying (x) the number of such Units for which a Right was exercisable hereunder immediately prior to such first occurrence of a Section 11(a)(ii) Event by (y) the Purchase Price in effect immediately prior to such first occurrence), and

(B) dividing that product (which, following the first occurrence of a Section 13 Event, shall be the “Purchase Price” for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d) hereof) per share of the Common Stock of such Principal Party on the date of consummation of such Section 13 Event;

provided, however, that the Purchase Price (as theretofore adjusted in accordance with Section 11(a)(ii) hereof) and the number of shares of Common Stock of such Principal Party so receivable upon exercise of a Right shall be subject to further adjustment as

appropriate in accordance with Section 11(f) hereof to reflect any events occurring in respect of the Common Stock of such Principal Party after the occurrence of such Section 13 Event;

(ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement;

(iii) the term “Company” shall thereafter be deemed to refer to such Principal Party in all respects, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence of a Section 13 Event;

(iv) such Principal Party shall take such steps (including, but not limited to, the authorization and reservation of a sufficient number of shares of its Common Stock in accordance with Section 9 hereof) in connection with the consummation of any such transaction as may be necessary to assure that the provisions of this Agreement shall thereafter be applicable, as nearly as reasonably may be, in relation to its shares of Common Stock thereafter deliverable upon the exercise of the Rights;

(v) such Principal Party shall take such steps as may be necessary to assure that, upon the subsequent occurrence of any merger, consolidation, sale of all or substantially all of the assets, recapitalization, reclassification of shares, reorganization or other extraordinary transaction in respect of such Principal Party, each holder of a Right shall thereupon be entitled to receive, upon exercise of a Right and payment of the Purchase Price, such cash, shares, rights, warrants and other property which such holder would have been entitled to receive had it, at the time of such transaction, owned the shares of Common Stock of the Principal Party purchasable upon the exercise of a Right, and such Principal Party shall take such steps (including, but not limited to, reservation of shares of stock) as may be necessary to permit the subsequent exercise of the Rights in accordance with the terms hereof for such cash, shares, rights, warrants and other property; and

(vi) the provisions of Section 11(a)(ii) hereof shall be of no further effect following the first occurrence of any Section 13 Event.

(b) “Principal Party” shall mean:

(i) in the case of any transaction described in clause (x) or (y) of the first sentence of Section 13(a) hereof, (A) the Person that is the issuer of any securities into which shares of Company Common Stock are converted in such merger or consolidation, or, if there is more than one such issuer, the issuer of Common Stock that has the highest aggregate current market price (determined pursuant to Section 11(d) hereof) and (B) if no securities are so issued, the Person that is the other party to such merger or consolidation, or, if there is more than one such Person, the Person the

Common Stock of which has the highest aggregate current market price (determined pursuant to Section 11(d) hereof); and

(ii) in the case of any transaction described in clause (z) of the first sentence of Section 13(a) hereof, the Person that is the party receiving the largest portion of the assets, cash flow or earning power transferred pursuant to such transaction or transactions, or, if each Person that is a party to such transaction or transactions receives the same portion of the assets, cash flow or earning power transferred pursuant to such transaction or transactions or if the Person receiving the largest portion of the assets, cash flow or earning power cannot be determined, whichever Person the Common Stock of which has the highest aggregate current market price (determined pursuant to Section 11(d) hereof);

provided, however, that in any such case:

(1) if the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve-month period registered under Section 12 of the Exchange Act (“Registered Common Stock”) or such Person is not a corporation, and such Person is a direct or indirect Subsidiary of another Person that has Registered Common Stock outstanding, “Principal Party” shall refer to such other Person;

(2) if the Common Stock of such Person is not Registered Common Stock or such Person is not a corporation, and such Person is a direct or indirect Subsidiary of another Person but is not a direct or indirect Subsidiary of another Person which has Registered Common Stock outstanding, “Principal Party” shall refer to the ultimate parent entity of such first-mentioned Person;

(3) if such Person is directly or indirectly controlled by more than one Person, and one or more of such other Persons has Registered Common Stock outstanding, “Principal Party” shall refer to whichever of such Persons is the issuer of the Registered Common Stock having the highest aggregate current market price (determined pursuant to Section 11(d) hereof); and

(4) if such Person is directly or indirectly controlled by more than one Person, and none of such other Persons have Registered Common Stock outstanding, “Principal Party” shall refer to whichever ultimate parent entity is the corporation having the greatest stockholders equity or, if no such ultimate parent entity is a corporation, shall refer to whichever ultimate parent entity is the entity having the greatest net assets.

(c) The Company shall not consummate any such consolidation, merger, sale or transfer unless the Principal Party shall have a sufficient number of authorized shares of its Common Stock 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 unless prior thereto 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 paragraphs (a) and (b) of this Section 13 and further providing that the Principal Party, as soon as practicable after the date of such Section 13 Event, at its own expense, shall:

(i) (A) file on an appropriate form a registration statement under the Securities Act with respect to the Rights and the securities purchasable upon exercise of the Rights, (B) use its best efforts to cause such registration statement to become effective as soon as practicable after filing and remain effective (and to include a prospectus complying with the requirements of the Securities Act) until the Expiration Date, and (C) take all such action as may be required to enable the Principal Party to issue the securities purchasable upon exercise of the Rights and to assure that any acquisition of such securities upon the exercise of the Rights complies with any applicable state securities or “blue sky” laws, including but not limited to the registration or qualification of such securities under all requisite securities and “blue sky” laws of the various states and the listing of such securities on such exchanges and trading markets as may be necessary or appropriate; 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.

(d) In case the Principal Party which is to be a party to a transaction referred to in this Section 13 has a provision in any of its authorized securities or in its certificate of incorporation or by-laws or other instrument governing its corporate affairs, which provision would have the effect of (i) causing such Principal Party to issue, in connection with, or as a consequence of, the consummation of a transaction referred to in this Section 13, shares of Common Stock or common stock equivalents of such Principal Party at less than the then current market price per share (determined pursuant to Section 11(d) hereof) or securities exercisable for, or convertible into, Common Stock or common stock equivalents of such Principal Party at less than such then current market price (other than to holders of Rights pursuant to this Section 13) or (ii) providing for any special payment, tax or similar provisions in connection with the issuance of the Common Stock of such Principal Party pursuant to the provisions of this Section 13; then, in such event, the Company shall not consummate any such transaction unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing that the provision in question of such Principal Party shall have been cancelled, waived or amended, or that the authorized securities shall be redeemed, so that the applicable provision will have no effect in connection with, or as a consequence of, the consummation of the proposed transaction.

(e) The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a Section 13 Event shall occur, any Rights which theretofore have not been exercised pursuant to Section 11(a)(ii) shall thereafter be exercisable only in the manner and for the securities described in Section 13(a).

Section 14. Fractional Rights and Fractional Shares.

(a) The Company shall not be required to issue fractions of Rights, except prior to the Distribution Date as provided in Section 11(p) hereof, or to distribute Rights Certificates which evidence fractional Rights. In lieu of issuing such fractional Rights, there shall be paid to the Persons to which such fractional Rights would otherwise be issuable an amount in cash equal to such fraction of the market value of a whole Right. For purposes of this

Section 14(a), the 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:

(y) if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by Nasdaq or such other system then in use, or

(z) 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.

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 shall be used and such determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(b) The Company shall not be required to issue fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates which evidence such fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share of Preferred Stock); provided, however, that in lieu of fractions of shares of Preferred Stock which are integral multiples of one one-hundredth of a share of Preferred Stock, the Company may provide for the issuance of depositary receipts pursuant to Section 7(c) hereof. In lieu of such fractional shares of Preferred Stock that are not integral multiples of one one-hundredth of a share, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the then current market price of a share of Preferred Stock on the day of exercise, determined in accordance with Section 11(d) hereof.

(c) The Company shall not be required to issue fractions of shares of Company Common Stock upon exercise of the Rights or to distribute certificates which evidence fractional shares of Company Common Stock. In lieu of such fractional shares of Company Common Stock, the Company may pay to the registered holders of Rights 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 (1) share of Company Common Stock. For purposes of this Section 14(c), the current market value of one share of Company Common Stock shall be the closing price per share of Company Common Stock (as determined pursuant to Section 11(d)(i) hereof) on the Trading Day immediately prior to the date of such exercise.

(d) The holder of a Right by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 14.

Section 15. Rights of Action. All rights of action in respect of this Agreement, other than rights of action vested in the Rights Agent pursuant to Section 18 hereof, are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of certificates representing shares of Company Common Stock); and any registered holder of a Rights Certificate (or, prior to the Distribution Date, of a certificate representing shares of Company Common Stock), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of a certificate representing shares of Company Common Stock), may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company or any other Person to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and shall be entitled to specific performance of the obligations hereunder and injunctive relief against actual or threatened violations of the obligations hereunder of any Person subject to this Agreement.

Section 16. 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 Company Common Stock;

(b) after the Distribution Date, the Rights Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates duly executed;

(c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Distribution Date, the associated Company Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights Certificates or the associated Company Common Stock certificate made by any Person 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 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 any 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, judgment 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, judgment or ruling lifted or otherwise overturned as promptly as practicable.

Section 17. Rights Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the number of shares of Preferred Stock or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or, except as provided in Section 25 hereof, to receive notice of meetings or other actions affecting stockholders, or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof. This Section 17 shall also apply to holders, as such, of Rights prior to the issuance of Rights Certificates.

Section 18. Concerning the Rights Agent.

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable out-of-pocket expenses, including reasonable fees and disbursements of its counsel, incurred in connection with the execution and administration of this Agreement and the exercise and performance of its duties hereunder. The Company shall indemnify the Rights Agent for, and 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 or the exercise or performance of its duties hereunder, including, without limitation, the reasonable costs and expenses of defending against a claim of liability hereunder.

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

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

(a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the corporate trust or stockholder services businesses 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 document or any further act on the part of any of the parties hereto; provided, however, that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

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

Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel 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 (including, without limitation, the identity of any Acquiring Person and the determination of current market price) be proved or established by the Company prior to taking or omitting any action hereunder, such fact or matter (unless other evidence in respect thereof be specified herein) may be deemed to be conclusively proved and established by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action taken or omitted 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 Rights Certificates or be

required to verify the same (except as to its countersignature on such Rights Certificates), 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 responsible for the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or for the validity or execution of any Rights Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or failure by the Company to satisfy conditions contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any adjustment required under the provisions of Section 11 or Section 13 hereof or 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 Rights Certificates after actual notice of any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Preferred Stock or any other securities to be issued pursuant to this Agreement or any Rights Certificate or as to whether any shares of Preferred Stock or any other securities will, when so issued, be validly authorized and issued, fully paid and nonassessable.

(f) The Company shall perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further acts, instruments and assurances as may reasonably be required by the Rights Agent for the performance by the Rights Agent of its duties under this Agreement.

(g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer of the Company, and to apply to such officers for advice or instructions in connection with its duties, and shall not be liable for any action taken, or omitted to be taken by it in good faith in accordance with instructions of any such officer.

(h) The Rights Agent and any stockholder, 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 have a pecuniary interest 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.

(j) 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 or in the exercise of its rights hereunder if the Rights Agent shall have reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

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

Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty days’ prior notice in writing mailed to the Company and to each transfer agent for the Company Common Stock or Preferred Stock, by registered or certified mail, and, if such resignation occurs after the Distribution Date, to the holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon thirty days’ prior notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent for the Company Common Stock or Preferred Stock, by registered or certified mail, and, if such removal occurs after the Distribution Date, to the holders of the Rights 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 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 Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then any registered holder of any Rights 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) a corporation organized and doing business under the laws of the United States or any state of the United States in good standing, shall be authorized under applicable laws to exercise corporate trust or stock transfer or stockholder service powers and shall be subject to supervision or examination by federal or state authorities and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000 or (b) an Affiliate of a corporation described in clause (a). After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Company Common Stock or Preferred Stock, and, if such appointment occurs after the Distribution Date, mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent.

Section 22. Issuance of New Rights Certificates. Notwithstanding any of the provisions of this Agreement or the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change made in accordance with the provisions of this

Agreement in the Purchase Price or the number or kind or class of shares or other securities or property that may be acquired under the Rights Certificates.

In addition, in connection with the issuance or sale of shares by the Company of Company Common Stock following the Distribution Date and prior to the Expiration Date, the Company (a) shall, with respect to shares of Company Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement granted or awarded as of the Distribution Date, or upon the exercise, conversion or exchange of any other securities hereinafter issued by the Company, and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights 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 Rights Certificate would be issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

Section 23. Redemption and Termination.

(a) Subject to Section 31 hereof, the Company may, at its option, by action of the Board of Directors, at any time prior to the earlier of (i) the Close of Business on the tenth Business Day following the Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred prior to the Record Date, the Close of Business on the tenth Business Day following the Record Date) or (ii) the Final Expiration Date, redeem all but not less than all of the then-outstanding Rights at a redemption price of $.001 per Right, as such amount may be appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such redemption price being the “Redemption Price”). The Company may, at its option, by action of the Board of Directors, pay the Redemption Price either in shares of Company Common Stock (based on the current market price, as defined in Section 11(d) hereof, of the shares of Company Common Stock at the time of redemption) or cash or any other form of consideration deemed appropriate by the Board of Directors and the redemption of the Rights shall be effective at such time and on the basis and with such conditions as the Board of Directors may in its sole discretion establish. Notwithstanding anything in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event until such time as the Company’s right of redemption has expired.

(b) Immediately upon the action of the Board of Directors ordering the redemption of the Rights as provided in Section 23(a) above (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 for each Right so held. The Company shall promptly give notice of such redemption to the Rights Agent and the holders of the then-outstanding Rights by mailing such notice to all such holders at each holder’s 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 Company Common Stock, provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Any notice which is mailed in the manner herein provided shall be deemed

given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made.

(c) The Company may, at its option, discharge all of its obligations with respect to the Rights by (i) issuing a press release announcing the manner of redemption of the Rights in accordance with this Agreement, and (ii) mailing payment of the Redemption Price to the registered holders of the Rights as their last addresses as they appear on the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent of the Company Common Stock, and upon such action, all outstanding Rights and Rights Certificates shall be null and void without any further action by the Company.

(d) Neither the Company nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at any time in any manner, other than that specifically set forth in this Section 23 or in Section 24 hereof and other than in connection with the purchase or repurchase by any of them of Company Common Stock prior to the Distribution Date.

Section 24. Exchange.

(a) The Company, upon resolution of the Board of Directors, may, at its option, at any time after the first occurrence of a Section 11(a)(ii) Event, exchange all or part of the then-outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to Section 7(e) hereof) for Units of Preferred Stock or shares of Company Common Stock (at the election of the Board of Directors) at an exchange ratio of one Unit of Preferred Stock or one share of Company Common Stock, as the case may be, per Right, as appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such exchange ratio being the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than an Exempt Person), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of shares of Company Common Stock aggregating 50% or more of the shares of Company Common Stock then outstanding. From and after the occurrence of a Section 13(a) Event, any Rights that theretofore have not been exchanged pursuant to this Section 24(a) shall thereafter be exercisable only in accordance with Section 13 and may not be exchanged pursuant to this Section 24(a). The exchange of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish.

(b) Immediately upon the action of the Board of Directors ordering the exchange of any Rights pursuant to Section 24(a), and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive that number of Units of Preferred Stock or shares of Company Common Stock, as the case may be, equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly provide public notice of any such exchange; provided, however, that the failure to give or any defect in such notice shall not affect the validity of such exchange. The Company shall promptly mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of

exchange shall state the method by which the exchange of Units of Preferred Stock or shares of Company Common Stock, as the case may be, for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights.

(c) In the event that the number of Units of Preferred Stock or shares of Company Common Stock, as the case may be, which are authorized by the Company’s Certificate of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not sufficient to permit any exchange of Rights as contemplated in accordance with this Section 24, then the Company, at the election of the Board of Directors, shall take all such action as may be necessary to authorize additional shares of Preferred Stock or Company Common Stock, as the case may be, for issuance upon exchange of the Rights.

(d) The Company shall not be required to issue fractions of Units of Preferred Stock or fractions of shares of Company Common Stock or to distribute certificates which evidence fractional Units or fractional shares. In lieu of issuing fractional Units or fractional shares, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exchanged as herein provided an amount in cash equal to the same fraction of the current market price (determined pursuant to Section 11(d) hereof) of one Unit of Preferred Stock or one share of Company Common Stock, as the case may be, on the Trading Day immediately prior to the date of exchange pursuant to this Section 24.

Section 25. 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 Stock or to make any other distribution to the holders of Preferred Stock (other than a regular periodic cash dividend paid out of funds legally available therefor),

(ii) to offer to the holders of Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options,

(iii) to effect any reclassification of its Preferred Stock (other than a reclassification involving only the subdivision of outstanding shares of Preferred Stock),

(iv) to effect any consolidation or merger into or with any other Person (other than a wholly owned Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), 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, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its wholly owned Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), 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 Rights Certificate, to the extent feasible and in accordance with Section 26 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights 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 shares of Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date for determining holders of the shares of Preferred Stock for purposes of such action, and in the case of any such other action, at least twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the shares of Preferred Stock, whichever shall be the earlier; provided, however, no such notice shall be required pursuant to this Section 25, if any wholly owned Subsidiary of the Company effects a consolidation or merger with or into, or effects a sale or other transfer of assets, cash flow or earnings power to, any other wholly owned Subsidiary of the Company.

(b) In case any Triggering Event shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to each holder of a Rights Certificate, to the extent feasible and in accordance with Section 26 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) or Section 13 hereof, as the case may be, and (ii) all references in the preceding paragraph (a) to Preferred Stock shall be deemed thereafter to refer also to Company Common Stock and/or, if appropriate, other securities of the Company.

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 27, the Rights Agent shall execute such supplement or amendment.

Prior to the Distribution Date, the interests of the holders of Rights shall be deemed coincident with the interests of the holders of Company Common Stock.

Section 28. 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.

Except as otherwise specifically provided herein, the Board of Directors shall have the exclusive power and authority to administer this Agreement and to exercise all rights and powers specifically granted

to the Board of Directors or to the Company, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power (i) to interpret the provisions of this Agreement, and (ii) to make all determinations deemed necessary or advisable for the administration of this Agreement (including, without limitation, a determination whether to redeem or not redeem the rights or to amend this Agreement and whether any proposed amendment adversely affects the interest of the holders of Rights Certificates). All such actions, calculations, interpretations and determinations (including, for purposes 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 or any member thereof to any liability to the holders of the Rights.

(c) The members of the TIDE Committee shall be appointed by the Board of Directors and comprised of members of the Board of Directors who are not officers, employees or Affiliates of the Company.

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 Rights Certificates (and, prior to the Distribution Date, registered holders of shares of Company Common Stock) 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 Rights Certificates (and, prior to the Distribution Date, registered holders of shares of Company Common Stock).

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; provided, however, that notwithstanding anything in this Agreement to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to be invalid, void or unenforceable and the Board of Directors determines in its good faith judgment that severing the invalid language from this Agreement would adversely affect the purpose or effect of this Agreement and the Rights shall not then be redeemable, the right of redemption set forth in Section 23 hereof shall be reinstated and shall not expire until the Close of Business on the tenth Business Day following the date of such determination by the Board of Directors.

Section 33. Governing Law. This Agreement, each Right and each Rights Certificate issued hereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed entirely in such State.

Rights Certificate

SOURCEFIRE, INC.

This certifies that , or registered assigns, is the registered holder of the number of Rights set forth above, each of which entitles the registered holder thereof, subject to the terms and conditions of the Rights Agreement dated as of October 30, 2008, as amended from time to time (the “Rights Agreement”) (terms defined therein being used herein with the same meaning unless otherwise defined herein), between Sourcefire, Inc., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Co., as Rights Agent (which term shall include any successor Rights Agent under the Rights Agreement), to purchase from the Company at any time after the Distribution Date and prior to the Expiration Date, at the office of the Rights Agent, one one-hundredth of a fully paid and nonassessable share of Series A Junior Participating Preferred Stock, par value $.001 per share (the “Preferred Stock”), of the Company at the Purchase Price initially of $30.00 per one one-hundredth share of Preferred Stock (each such one one-hundredth of a share being a “Unit”), upon presentation and surrender of this Rights Certificate with the Election to Purchase and related certificate duly executed. The number of Rights evidenced by this Rights Certificate (and the number and kind of shares which may be purchased upon exercise thereof) and the Purchase Price per Unit set forth above, are the number and Purchase Price as of , 20___, based on the Preferred Stock as constituted at such date.

Upon the occurrence of a Section 11(a)(ii) Event, if the Rights evidenced by this Rights Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of any such Acquiring Person or (ii) under certain circumstances described in the Rights Agreement, a direct or indirect transferee of any such Acquiring Person, Associate or Affiliate, including a transferee of any person who, after such transfer, becomes an Acquiring Person or an Affiliate or Associate of an Acquiring Person, such Rights shall become null and void and no holder hereof

A-1

shall have any right with respect to such Rights from and after the occurrence of such Section 11(a)(ii) Event.

In certain circumstances described in the Rights Agreement, the Rights evidenced hereby may entitle the registered holder thereof to purchase capital stock of an entity other than the Company or receive common stock, cash or other assets, all as provided in the Rights Agreement.

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

This Rights Certificate is subject to all of the terms and conditions of the Rights Agreement, which terms and conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Company and the holders of the Rights Certificates, which limitations of rights include the temporary suspension of the exercisability of such Rights under the specific circumstances set forth in the Rights Agreement. Copies of the Rights Agreement are on file at the principal office of the Rights Agent and are available from the Rights Agent upon written request.

This Rights Certificate, with or without other Rights Certificates, upon surrender at the office of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing an aggregate number of Rights equal to the aggregate number of Rights evidenced by the Rights Certificate or Rights Certificates surrendered. If this Rights Certificate shall be exercised in part, the registered holder shall be entitled to receive, upon surrender hereof, another Rights Certificate or Rights Certificates for the number of whole Rights not exercised.

Subject to the provisions of the Rights Agreement, the Rights evidenced by this Certificate may be redeemed by the Company under certain circumstances at its option at a redemption price of $.001 per Right (as such amount may be adjusted pursuant to the Rights Agreement), at any time prior to the earlier of the Close of Business on (i) the tenth business day following the Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred prior to the Record Date, the Close of Business on the tenth Business Day following the Record Date) and (ii) the Final Expiration Date. In addition, subject to the provisions of the Rights Agreement, the Rights may be exchanged, in whole or in part, for Units of Preferred Stock or shares of the Common Stock of the Company. Immediately upon the action of the Board of Directors of the Company authorizing any such exchange, and without any further action or any notice, the Rights (other than Rights which are not subject to such exchange) will terminate and the Rights will only enable holders to receive the shares issuable upon such exchange.

No fractional shares of Preferred Stock will be issued upon the exercise of any Right or Rights evidenced hereby (other than fractions which are integral multiples of one one-hundredth of a share of Preferred Stock, which may, at the election of the Company be evidenced by

A-2

depositary receipts), but in lieu thereof a cash payment will be made, as provided in the Rights Agreement.

No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Preferred Stock or of any other securities which may at any time be issuable on the exercise hereof, nor shall anything contained in the Rights Agreement or herein be construed to confer upon the holder hereof, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in the Rights Agreement), or to receive dividends of subscription rights, or otherwise, until the Rights evidenced by this Rights Certificate shall have been exercised as provided in the Rights Agreement.

(AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT),

SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

On October 29, 2008, the Board of Directors of Sourcefire, Inc. (the “Company”) authorized and declared a dividend of one right (“Right”) for each outstanding share of its Common Stock, par value $.001 per share (the “Company Common Stock”), to stockholders of record at the close of business on November 14, 2008 (the “Record Date”), and authorized the issuance of one Right for each share of Company Common Stock issued by the Company (except as otherwise provided in the Rights Agreement, as defined below) between the Record Date and the Distribution Date (as defined below). Each Right entitles the registered holder, subject to the terms of the Rights Agreement (as defined below), to purchase from the Company one one-hundredth of a share (a “Unit”) of Series A Junior Participating Preferred Stock, par value $.001 per share (the “Preferred Stock”), at a purchase price of $30.00 per Unit, subject to adjustment. The purchase price is payable by certified or bank check or money order payable to the order of the Rights Agent (as defined below). The description and terms of the Rights are set forth in a Rights Agreement between the Company and Continental Stock Transfer & Trust Co., as rights agent (the “Rights Agent”), dated as of October 30, 2008, as amended from time to time (the “Rights Agreement”).

The Rights Agreement (which includes the Certificate of Designation attached as Exhibit C thereto) has been filed with the Securities and Exchange Commission as Exhibit 4.1 to a Registration Statement on Form 8-A dated , 2008. Copies of the Rights Agreement and the Certificate of Designation are available free of charge from the Company. This summary description of the Rights Agreement, the Rights and the Preferred Stock does not purport to be complete and is qualified in its entirety by reference to all of the provisions of the Rights Agreement and the Certificate of Designation, including the definitions therein of certain terms, which Rights Agreement and Certificate of Designation are incorporated herein by reference.

The Rights Agreement

Certificates; Distribution Date. Initially, the Rights will attach to all certificates representing shares of outstanding Company Common Stock, and no separate Rights Certificates will be distributed. Subject to the provisions of the Rights Agreement, the Rights will separate

B-1

from the Company Common Stock and the “Distribution Date” will occur upon the earlier of (i) ten business days following a public announcement (the date of such announcement being the “Stock Acquisition Date”) that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired or otherwise obtained beneficial ownership (which includes, among other things, certain derivative or synthetic arrangements having characteristics of a long position in Company Common Stock) of 15% or more of the then-outstanding shares of Company Common Stock (or, if the tenth business day after the Stock Acquisition Date occurs before the Record Date, the close of business on the Record Date), and (ii) ten business days (or such later date as may be determined by action of the Board of Directors) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. Until the Distribution Date, (i) the Rights will be evidenced by Company Common Stock certificates and will be transferred with and only with such Company Common Stock certificates, (ii) new Company Common Stock certificates issued after the Record Date (also including shares distributed from Treasury) will contain a notation incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates representing outstanding Company Common Stock will also constitute the transfer of the Rights associated with the Company Common Stock represented by such certificates.

An “Acquiring Person” does not include certain persons specified in the Rights Agreement.

The Rights are not exercisable until the Distribution Date and will expire at the close of business on the tenth anniversary of the Rights Agreement unless earlier redeemed or exchanged by the Company as described below. Under certain circumstances, as provided in the Rights Agreement, the exercisability of the Rights may be suspended.

As soon as practicable after the Distribution Date, Rights Certificates will be mailed to holders of record of Company Common Stock as of the close of business on the Distribution Date (and to each initial holder of certain shares of Company Common Stock issued after the Distribution Date) and, thereafter, the separate Rights Certificates alone will represent the Rights.

Flip-In. If a person becomes an Acquiring Person, then each holder of a Right will thereafter have the right to receive, upon exercise, Units of Preferred Stock or, at the option of the Company, shares of Company Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right. The exercise price is the purchase price multiplied by the number of Units of Preferred Stock issuable upon exercise of a Right prior to the event described in this paragraph. Notwithstanding any of the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person or any affiliate or associate thereof (or certain transferees of any thereof) will be null and void.

Flip-Over. If, at any time following the date that any person becomes an Acquiring Person, (i) the Company is acquired in a merger or other business combination transaction and the Company is not the surviving corporation, (ii) any person merges with the Company and all or part of the Company Common Stock is converted or exchanged for securities, cash or property

B-2

of the Company or any other person or (iii) 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, each holder of a Right (except Rights which previously have been voided as described above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right.

Redemption. At any time until ten business days following the Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred prior to the Record Date, until ten business days following the Record Date), the Board of Directors may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (subject to adjustment in certain events) payable, at the election of the Board of Directors, in cash, shares of Company Common Stock or other consideration considered appropriate by the Board of Directors. Immediately upon the action of the Board of Directors ordering the redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the redemption price.

Exchange. The Company may, at any time after there is an Acquiring Person, until the time specified in the Rights Agreement, exchange all or part of the then-outstanding and exercisable Rights (other than Rights that shall have become null and void) for Units of Preferred Stock or shares of Company Common Stock pursuant to a one-for-one exchange ratio, subject to adjustment.

No Stockholder Rights; Taxation. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Units of Preferred Stock (or other consideration) or for common stock of the acquiring company or in the event of the redemption of Rights as set forth above.

Amendment. Any of the provisions of the Rights Agreement may be amended without the approval of the holders of the Rights or Company Common Stock at any time prior to the Distribution Date. After such date, the provisions of the Rights Agreement may be amended in order to cure any ambiguity, defect or inconsistency, to shorten or lengthen any time period under the Rights Agreement, or to make changes which do not adversely affect the interests of holders of Rights (excluding the interests of any Acquiring Person); provided, that no amendment shall be made to lengthen (i) the time period governing redemption at such time as the Rights are not redeemable or (ii) any other time period unless such lengthening is for the purpose of protecting, enhancing or clarifying the rights of, and/or the benefits to, the holders of Rights.

Independent Director Review. The Rights Agreement provides that a Three-Year Independent Director Evaluation Committee (the “TIDE Committee”) of the Board of Directors will review and evaluate the Rights Agreement in order to consider whether the maintenance of the Rights Agreement continues to be in the interests of the Company and its stockholders at least once every three years. The TIDE Committee will be comprised of members of the Board of Directors who are not officers, employees or Affiliates of the Company.

Description of Preferred Stock

The Units of Preferred Stock that may be acquired upon exercise of the Rights will be nonredeemable.

Each Unit of Preferred Stock will have a minimum preferential quarterly dividend of $0.01 per Unit or any higher per share dividend declared on the Company Common Stock.

In the event of liquidation, the holder of a Unit of Preferred Stock will receive a preferred liquidation payment equal to the greater of $1.00 per Unit and the per share amount paid in respect of a share of the Company Common Stock.

Each Unit of Preferred Stock will have one vote, voting together with the Company Common Stock.

In the event of any merger, consolidation or other transaction in which shares of Company Common Stock are exchanged, each Unit of Preferred Stock will be entitled to receive the per share amount paid in respect of each share of Company Common Stock.

The rights of holders of the Preferred Stock with respect to dividends, liquidation and voting, and in the event of mergers and consolidations, are protected by customary antidilution provisions.

The economic value of one Unit of Preferred Stock that may be acquired upon the exercise of each Right should approximate the economic value of one share of Company Common Stock.

EXHIBIT C
TO RIGHTS AGREEMENT

CERTIFICATE OF DESIGNATION
OF THE
SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
OF
SOURCEFIRE, INC.

The undersigned officer of Sourcefire, Inc., a Delaware corporation (the “Corporation”), DOES HEREBY CERTIFY:

That, pursuant to the authority conferred upon the Board of Directors of the Corporation by its Certificate of Incorporation (the “Certificate of Incorporation”), the said Board of Directors, at a duly called meeting held on October 29, 2008, at which a quorum was present and acted throughout, adopted the following resolution, which resolution remains in full force and effect on the date hereof, creating a series of Preferred Stock having a par value of $.001 per share, designated as Series A Junior Participating Preferred Stock (the “Series A Junior Participating Preferred Stock”), out of the Corporation’s authorized shares of preferred stock of the par value of $.001 per share (the “Preferred Stock”):

RESOLVED, that pursuant to the authority vested in the Board of Directors in accordance with the provisions of its Certificate of Incorporation, the Board of Directors does hereby create, authorize and provide for 300,000 shares of its authorized Preferred Stock to be designated and issued as the “Series A Junior Participating Preferred Stock,” having the relative rights, preferences and limitations that are set forth as follows:

1. Dividends and Distributions.

(A) Subject to the prior and superior rights of the holders of any shares of any other series of Preferred Stock or any other shares of stock of the Corporation ranking prior and superior to the shares of Series A Junior Participating Preferred Stock with respect to dividends, each holder of one one-hundredth (1/100) of a share (a “Unit”) of Series A Junior Participating Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for that purpose, (i) quarterly dividends payable in cash on the last day of February, May, August and November in each year (each such date being a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a Unit of Series A Junior Participating Preferred Stock, in an amount per Unit (rounded to the nearest cent) equal to the greater of (a) $0.01 or (b) subject to the provision for adjustment hereinafter set forth, the aggregate per share amount of all cash dividends declared on shares of 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 a Unit of Series A Junior Participating Preferred Stock, and (ii) subject to the provision for adjustment hereinafter set forth, quarterly distributions (payable in kind) on each Quarterly Dividend Payment Date in an amount per Unit equal to the aggregate per share amount 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 shares of 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 a Unit of Series A Junior Participating Preferred Stock. In the event that the Corporation shall at any time after October 30, 2008 (the “Rights Declaration Date”) (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine outstanding shares of Common Stock into a smaller number of shares, then in each such case the amount to which the holder of a Unit of Series A Junior Participating Preferred Stock was entitled immediately prior to such event under clause (i) (b) or clause (ii) of the preceding sentence shall be adjusted by multiplying such amount by a fraction (y) the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and (z) the denominator of which shall be 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 Units of Series A Junior Participating Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the shares of Common Stock (other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock, by reclassification or otherwise); 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 $0.01 per Unit on the Series A Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and shall be cumulative on each outstanding Unit of Series A Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issuance of a Unit of Series A Junior Participating Preferred Stock, unless the date of issuance of such Unit is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such Unit shall begin to accrue from the date of issuance of such Unit, or unless the date of issuance is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of Units of Series A Junior Participating Preferred Stock 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 Units of Series A Junior Participating Preferred Stock in an amount less than the aggregate amount of all such dividends at the time accrued and payable on such Units shall be allocated pro rata on a Unit-by-Unit basis among all Units of Series A Junior Participating Preferred Stock at the time outstanding. The Board of Directors may fix a record date for the determination of holders of Units of Series A Junior Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof.

2. Voting Rights. The holders of Units of Series A Junior Participating Preferred Stock shall have the following voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each Unit of Series A Junior Participating Preferred Stock shall entitle the holder thereof to one vote on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall, at any time after the Rights Declaration Date, (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine the outstanding shares of Common Stock into a smaller number of shares, then in each such case the number of votes per Unit to which holders of Units of Series A Junior Participating Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction (y) the numerator of which shall be the number of shares of Common Stock outstanding immediately after such event and (z) the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein, in the Certificate of Incorporation or the Bylaws of the Corporation or as required by law, the holders of Units of Series A Junior Participating Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation.

3. Certain Restrictions.

(A) Whenever quarterly dividends or other dividends or distributions payable on Units of Series A Junior Participating Preferred Stock as provided herein are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on outstanding Units of Series A Junior Participating Preferred Stock shall have been paid in full, the Corporation shall not:

(i) declare or pay dividends on, or make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of junior stock;

(ii) declare or pay dividends on, or make any other distributions on, any shares of parity stock, except dividends paid ratably on Units of Series A Junior Participating Preferred Stock and shares of all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of such Units and all such shares are then entitled;

(iii) redeem or purchase or otherwise acquire for consideration shares of any parity stock, 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 junior stock; or

(iv) redeem or purchase or otherwise acquire for consideration any Units of Series A Junior Participating Preferred Stock, or any shares of parity stock, 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 Units and shares of parity stock 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 and 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 3, purchase or otherwise acquire such shares at such time and in such manner.

4. Reacquired Shares. Any Units of Series A Junior Participating Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such Units shall, upon their cancellation, become authorized but unissued shares (or fractions of shares) of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

5. Liquidation, Dissolution or Winding Up.

(A) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, no distribution shall be made (i) to the holders of shares of junior stock, unless the holders of Units of Series A Junior Participating Preferred Stock shall have received, subject to adjustment as hereinafter provided in paragraph (B), the greater of either (a) $1.00 per Unit plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not earned or declared, to the date of such payment, or (b) the amount equal to the aggregate per share amount to be distributed to holders of shares of Common Stock, or (ii) to the holders of shares of parity stock, unless simultaneously therewith distributions are made ratably on Units of Series A Junior Participating Preferred Stock and all other shares of such parity stock in proportion to the total amounts to which the holders of Units of Series A Junior Participating Preferred Stock are entitled under clause (i)(a) of this sentence and to which the holders of shares of such parity stock are entitled, in each case upon such liquidation, dissolution or winding up.

(B) In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine outstanding shares of Common Stock into a smaller number of shares, then in each such case the aggregate amount to which holders of Units of Series A Junior Participating Preferred Stock were entitled immediately prior to such event pursuant to clause (i)(b) of paragraph (A) of this Section 5 shall be adjusted by multiplying such amount by a fraction (y) the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and (z) the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

6. 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 converted into other stock or securities, cash and/or any other property, then in any such case Units of Series A Junior Participating Preferred Stock shall at the same time be similarly exchanged for or converted into an amount per Unit (subject to the provision for

adjustment hereinafter set forth) equal to 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 converted or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock, or (iii) combine outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the immediately preceding sentence with respect to the exchange or conversion of Units of Series A Junior Participating Preferred Stock shall be adjusted by multiplying such amount by a fraction (y) the numerator of which shall be the number of shares of Common Stock that are outstanding immediately after such event and (z) the denominator of which shall be the number of shares of Common Stock that were outstanding immediately prior to such event.

7. Redemption. The Units of Series A Junior Participating Preferred Stock and shares of Series A Junior Participating Preferred Stock shall not be redeemable.

8. Ranking. The Units of Series A Junior Participating Preferred Stock and shares of Series A Junior Participating Preferred Stock shall rank junior to all other series of the Preferred Stock and to any other class of Preferred Stock that hereafter may be issued by the Corporation as to the payment of dividends and the distribution of assets, unless the terms of any such series or class shall provide otherwise.

9. Fractional Shares. The Series A Junior Participating Preferred Stock may be issued in Units or other fractions of a share, which Units or other fractions shall entitle the holder, in proportion to such holder’s Units or other fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Participating Preferred Stock.

10. Amendment. At any time when any Units of Series A Junior Participating Preferred Stock are outstanding, neither the Certificate of Incorporation of the Corporation nor this Certificate of Designation shall be amended in any manner which would materially alter or change the powers, preferences or special rights of the Units of Series A Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a majority or more of the outstanding Units of Series A Junior Participating Preferred Stock, voting separately as a class.

11. Certain Definitions. As used in this resolution with respect to the Series A Junior Participating Preferred Stock, the following terms shall have the following meanings:

(A) The term “Common Stock” shall mean the class of stock designated as the common stock, par value $.001 per share, of the Corporation at the date hereof or any other class of stock resulting from successive changes or reclassification of the common stock.

(B) The term “junior stock” (i) as used in Section 3, shall mean the Common Stock and any other class or series of capital stock of the Corporation over which the Series A Junior Participating Preferred Stock has preference or priority as to dividends and (ii) as used in Section 5, shall mean the Common Stock and any other class or series of capital stock of the

Corporation over which the Series A Junior Participating Preferred Stock has preference or priority in any liquidation, dissolution or winding up of the Corporation.

(C) The term “parity stock” (i) as used in Section 3, shall mean any class or series of capital stock of the Corporation hereafter authorized or issued ranking pari passu with the Series A Junior Participating Preferred Stock as to dividends and (ii) as used in Section 5, shall mean any class or series of capital stock of the Corporation ranking pari passu with the Series A Junior Participating Preferred Stock in any liquidation, dissolution or winding up.

IN WITNESS WHEREOF, Sourcefire, Inc. has caused this Certificate of Designation to be signed by its Chief Executive Officer this 30th day of October 2008.
