Sourcefire, Inc. Executive Change in Control Severance Plan

Effective March 31, 2008

As Amended Effective March 31, 2011

ARTICLE 1

ADOPTION AND NATURE OF PLAN

1.1 Adoption of Plan. The Sourcefire, Inc. Executive Change in Control Severance Plan (the “Plan”) is hereby established, effective as of March 31, 2008, as amended effective as of March 31, 2011, to provide separation pay and other severance benefits for eligible executives of Sourcefire, Inc. (the “Company”) in the event of their termination of employment with the Company under the circumstances described in the Plan.

1.2 Nature of Plan.

(a) The Plan is an “employee welfare benefit plan” within the meaning of Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), providing separation pay and severance benefits. This document constitutes both the plan document and the summary plan description for the Plan. Your ERISA rights are described at the end of this document. This document is provided to you as required by XXXXX. You should read all parts of this description carefully so that you will not only understand the ways in which the Plan may benefit you, but also certain exclusions to coverage and limitations on the receipt of benefits which may apply to you. This Plan supersedes and replaces any and all prior Company-sponsored severance or retention plans, programs, policies or practices for the individuals covered hereunder.

(b) It is the Company’s intention to operate the Plan in a manner consistent with the requirements applicable to “separation pay plans” providing benefits in the case of involuntary separation from service under Section 1.409A-1(b)(9) of the Treasury regulations such that the severance pay and other benefits available under the Plan will be exempt from Section 409A of the Internal Revenue Code, as amended (the “Code”) and shall be administered and operated in conformity with this intention; provided, however, that in the event and to the extent amounts payable under the Plan are or become subject to Section 409A of the Code, it is the Company’s intention that such amounts be payable in a manner consistent with the requirements of such Code section.

ARTICLE 3

ELIGIBILITY TO PARTICIPATE

3.1 Notice of Eligibility; Participation Agreement. The Plan Administrator may, from time to time, determine those key executives of the Company who are generally eligible to join the Plan (the “Eligible Executives”), and, upon making such a determination, will provide a Notice of Eligibility to such Eligible Executives specifying the particular Severance Benefits to which they may become entitled upon their Qualifying Termination; provided, however, that no Eligible Executive will commence participation in the Plan prior to his or her execution and submission of a Participation Agreement in substantially the form attached hereto as Exhibit B (or such other form as the Plan Administrator may specify). An Eligible Executive who has submitted an executed Participation Agreement to the Plan Administrator will be referred to as a “Participant.”

ARTICLE 4

SEVERANCE BENEFITS

4.1 Eligibility for Severance Benefits. A Participant who experiences a Qualifying Termination will be eligible to receive the Severance Benefits described in Section 4.3 below, subject to the limitations described in Section 4.4.

4.2 Accrued and Unpaid Amounts. Notwithstanding Section 4.4(a) below, upon a Participant’s Termination of Employment for any reason, he or she will be entitled to receive payment of any Base Salary, bonus or incentive compensation, expense reimbursements, and accrued vacation benefits that have been earned but not paid at the time of his or her Termination of Employment. All such amounts shall be paid to the terminated Participant within ten (10) days of his or her Termination Date.

4.3 Severance Benefits. Subject to Section 4.4 below, a Participant who is otherwise eligible to receive Severance Benefits under the Plan may be entitled to receive one or more of the following Severance Benefits, as specified in the Participant’s Notice of Eligibility, following his or her Qualifying Termination.

(a) Salary Continuation Benefits.

(i) A Participant’s salary continuation benefits will be equal to a pro-rata portion of the Participant’s Base Salary paid over the applicable Severance Period.

(ii) Subject to Section 7.2(b) below (relating to certain payment subject to Section 409A of the Code) and except as otherwise provided in the Participant’s Notice of Eligibility, salary continuation benefits will be paid for the duration of the Severance Period in substantially-equal semi-monthly installments in accordance with the Company’s standard payroll procedures, commencing on the second payroll date following the date on which the Participant’s Release becomes effective and irrevocable. Notwithstanding the foregoing, any remaining salary continuation benefits that are outstanding at the time of a Participant’s death

Page 6 of 17

will be paid to his or her designated Beneficiary in a single lump-sum payment within sixty (60) days following the delivery of satisfactory evidence of the Participant’s death to the Plan Administrator.

(b) Continued Welfare Benefits. If a Participant and/or his or her covered dependents timely elect(s) to receive health care continuation coverage as provided by COBRA, the Company will pay the same percentage of the monthly cost of his or her COBRA coverage as it paid for the Participant’s group health coverage during his or her active employment for the duration of the Severance Period. During any such Company-subsidized COBRA coverage period, the Participant will be responsible for payment of the remainder of the cost of his or her COBRA coverage, as specified in the COBRA notice to be supplied by the Company following the Participant’s Qualifying Termination. Notwithstanding the foregoing, if at any time the Company determines that its partial subsidy of the Participant’s COBRA premiums would result in a violation of the nondiscrimination rules of Code Section 105(h)(2) or any statute or regulation of similar effect (including but not limited to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of providing the subsidized COBRA premiums described above, the Company will instead pay a fully taxable cash payment equal to the Company’s portion of the applicable COBRA premiums for that month (such amount, the “Special Severance Payment”) to the Participant on the last day of each month of the remainder of the Benefit Period. All periods of Company-subsidized coverage will be taken into account for purposes of determining the Participant’s maximum period of COBRA entitlement. Following the end of the Company-subsidized coverage period, the Participant will be responsible for payment of his or her entire COBRA premium, to the extent the Participant continues to be entitled to COBRA coverage at that time. Notwithstanding the foregoing, in the event the terminated Participant becomes covered under another employer’s group health plan (other than a plan which imposes a preexisting condition exclusion unless the preexisting condition exclusion does not apply) or otherwise ceases to be eligible for COBRA coverage during the period provided in this Section 4.3(b), the Company shall cease payment of its portion of the COBRA premiums or the Special Severance Payments, as applicable.

(c) Accelerated Vesting of Equity Awards. The Participant’s outstanding and unvested stock options will accelerate and become vested, and the restrictions applicable to his or her outstanding restricted stock award(s) will lapse and become vested, as follows:

(i) the vesting of Participant’s outstanding and unvested stock options will accelerate and become fully vested; and

(ii) the restrictions applicable to each of the Participant’s outstanding awards of restricted stock and restricted stock units will lapse and become vested by fifty percent (50%) of the total shares originally subject to such award; provided, however, that in the event that as of Participant’s Date of Termination there are not a sufficient number of shares subject to restrictions (with respect to such award) to allow for the lapse described above, either in full or in part, then, the restrictions shall lapse (with respect to such award), as necessary to give effect to the restriction lapse described in this subsection 4.3(c)(ii), up to the number of restricted shares or restricted stock units then subject to such award.

Page 7 of 17

4.4 Loss of Eligibility. A Participant who is otherwise eligible to receive Severance Benefits upon his or her Qualifying Termination will forfeit such eligibility and any entitlement to some or all of the payments and benefits available under the Plan in any of the following circumstances.

(a) Failure to Provide Effective Release. All benefits provided under the Plan are in consideration of a Participant’s execution of a Release. If a Participant does not properly execute such a Release within forty-five (45) days from his or her Termination Date or revokes his or her Release after submitting it, the Participant will not be entitled to any Severance Benefits otherwise available under the Plan.

(b) Alternative Employment. A Participant who secures alternative employment during the Severance Period will forfeit his or her entitlement to receive further Company-funded subsidies for COBRA premiums but, subject to the terms of the Plan and his or her Participation Agreement, will remain eligible to receive salary continuation benefits.

(c) Violation of Non-Disclosure, Non-Competition, or Non-Solicitation Requirements. A Participant will forfeit any entitlement to Severance Benefits under the Plan if the Plan Administrator determines that the Participant has materially breached his or her Assignment of Inventions, Non-Disclosure, Non-Solicitation and Non-Competition Agreement with the Company with respect to Participant’s continuing obligations of non-disclosure, non-solicitation or non-competition thereunder, as set forth in Sections 1, 5 and 6 thereof respectively. To the extent permitted by law, if the Plan Administrator determines that the Participant has so materially breached his or her Assignment of Inventions, Non-Disclosure, Non-Solicitation and Non-Competition Agreement with the Company, the Plan Administrator and the Company will immediately cease any unpaid Severance Benefits and it will have the right to seek repayment of any such Severance Benefits that have already been made, without prejudice to any other remedies that may be available to the Company.

(d) Non-Qualifying Termination. A Participant whose Termination of Employment does not constitute a Qualifying Termination will not be entitled to any Severance Benefits otherwise available under the Plan.

ARTICLE 5

GOLDEN PARACHUTE PROVISIONS

5.1 Best Payments Determination. In the event of an event constituting a change in the ownership or effective control of the Company or ownership of a substantial portion of the assets of the Company described in Section 280G(b)(2)(A)(i) of the Code, the Company, at its sole expense, shall cause its independent auditors promptly to review all payments, accelerations, distributions and benefits that have been made to or provided to, and are to be made, or may be made, to or provided to, the Participants under the Plan (irrespective of whether Severance Benefits or other payments are then payable to such Participants at that time), and any other agreement or plan under which they may individually or collectively benefit (collectively the “Original Payments”), to determine the applicability of Section 4999 of the Code to each of the Participants in connection with such event (other than under this Article 5). The Company’s

Page 8 of 17

independent auditors will perform this analysis in conformity with the foregoing provisions and will provide the affected Participants with a copy of their analysis and determination. Notwithstanding anything contained in this Plan to the contrary, to the extent that the Original Payments would be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Original Payments shall be reduced (but not below zero) to the extent necessary so that no Original Payment shall be subject to the Excise Tax, but only if, by reason of such reduction, the net after-tax benefit received by an Participant shall exceed the net after-tax benefit received by him or her if no such reduction was made. For purposes of the Plan, “net after-tax benefit” shall mean (a) the Original Payments which an Participant receives or is then entitled to receive from the Company that would constitute “parachute payments” within the meaning of Section 280G of the Code, less (b) the amount of all federal, state and local income taxes payable with respect to the foregoing calculated at the maximum marginal income tax rate for each year in which the foregoing shall be paid to an Participant (based on the rate in effect for such year as set forth in the Code as in effect at the time of the first payment of the foregoing), less (c) the amount of the Excise Tax imposed with respect to the payments and benefits described in (a) above. If a reduction is required by this provision, the Participant, in his or her sole and absolute discretion, may determine which Original Payments shall be reduced to the extent necessary so that no portion thereof shall be subject to the Excise Tax, and the Company shall pay such reduced amount to him or her. The fees and expenses of the Company’s auditor for its services in connection with the determinations and calculations contemplated by this provision will be borne by the Company.

ARTICLE 6

PLAN ADMINISTRATION; AMENDMENT AND TERMINATION

6.1 Administration of Plan. The Compensation Committee of the Board of Directors of the Company will serve as the Plan Administrator. The Plan Administrator is the “named fiduciary” of the Plan for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity. The Plan Administrator may delegate in writing to any other person(s) or committee all or any portion of its authority or responsibility with respect to the Plan at any time. The Plan Administrator shall, in its sole and absolute discretion, construe and interpret the terms and provisions of the Plan, and any issue arising out of, relating to, or resulting from the administration and operation of the Plan, which such construction or interpretation shall be final and binding on all persons, entities and parties, including, without limitation, any employees and shall be given the maximum possible deference allowed by law. When making a determination or calculation, the Plan Administrator shall, in its sole and absolute discretion, be entitled to rely upon information furnished by employees or other individuals or entities acting on their behalf. To the extent that any payment under the Plan may be made within a specified number of days on or after any date or the occurrence of any event, the date of payment shall be determined by the Plan Administrator in its sole discretion, and not by any Participant, Beneficiary, or other individual.

6.2 Amendment and Termination. The Company reserves the right, by written action of its Board of Directors (or its delegate), to amend, modify or terminate the Plan at any time, without advance notice to any employee; provided, however, that no such amendment,

Page 9 of 17

modification, or termination shall be effective with respect to the availability, amount or timing of payment of any Severance Benefit to the extent it adversely affects the entitlement of any Participant (without such Participant’s prior consent) who would otherwise be eligible to receive Severance Benefits, with respect to (i) a result of events or circumstances which occurred or arose prior to the date on which the Board of Directors (or its delegate) approved such amendment, modification, or termination, or (ii) any such amendment, modification, or termination which is deemed to become effective during the one (1) year period immediately following a Change in Control. Any action of the Company in amending or terminating the Plan will be taken in a non-fiduciary capacity. In the event of an Internal Revenue Service or Department of Labor ruling which has the effect of reclassifying the Plan as an “employee pension benefit plan” as defined in Section 3(2)(A) of the ERISA, the Plan will be automatically terminated effective at the date of such ruling. No communications in connection with the Plan made by any individual shall be effective to modify or amend the Plan unless duly executed on an appropriate form provided or approved by, and filed with, the Plan Administrator (including, but not limited to, a Notice of Eligibility or Participation Agreement).

6.3 ERISA Limitations.

(a) No payments made pursuant to the Plan are contingent, either directly or indirectly, upon a Participant’s retirement.

(b) In no event shall the amount of a Severance Benefit or similar benefits payable under the Plan exceed two (2) times the applicable Participant’s annual compensation paid during the year immediately preceding his or her Termination Date.

(c) Under no circumstances will any Severance Benefits or similar benefits under the Plan be payable to a Participant more that twenty-four (24) months following his or her Termination Date.

6.4 Claims and Appeals Procedures.

(a) Claims Procedures.

(i) Submission of Claims. Any employee or other person who believes he or she is entitled to any payment under the Plan may submit a claim in writing to the Plan Administrator. If the claim is denied (in full or in part), the claimant shall be provided a written or electronic response from the Plan Administrator.

(ii) Contents of Notice of Claims Denial. In the event the Plan Administrator denies a claim made under the Plan, the Plan Administrator’s will deliver a written response to the claimant including the following information: (1) the specific reason(s) for the denial; (2) reference to the specific Plan provision(s) upon which the denial was based; (3) a description of any additional or material information that is necessary for the appeal of the denied claim to be successful, and an explanation of why this information is necessary; (4) a description of any voluntary appeal procedures available under the Plan and your right to receive information about them; (5) an explanation of the review procedure summarized below, including the time limits applicable to the review procedures and the claimant’s rights to submit

Page 10 of 17

written comments and have them considered, the claimant’s right to review (upon request and at no charge) relevant documents and other information; and (6) statement that the claimant has a right to bring a civil action under Section 502(a) of ERISA following a denial of an appeal of the claim. If the Plan Administrator relied on an internal rule, guideline, protocol, or other similar criterion in denying the claim, then the Plan Administrator either will provide the claimant with a copy of the criterion or will notify the claimant that it relied on such a criterion and inform the claimant that he or she may request a copy of the criterion free of charge.

(iii) Timing of Delivery of Notice of Denial. The denial notice shall be furnished to the claimant no later than ninety (90) days after receipt of the claim by the Plan Administrator, unless the Plan Administrator determines that special circumstances require an extension of time for processing the claim. If the Plan Administrator determines than an extension of time for processing is required, then notice of the extension shall be furnished to the claimant prior to the termination of the initial ninety (90) day period. In no event shall such extension exceed a period of ninety (90) days from the end of such initial period. The notice shall inform the claimant of the following: (1) the special circumstances requiring the extension of time; (2) the date by which the claimant can expect a decision; (3) the standards for determining the claimant’s entitlement to benefits; (4) the unresolved issue(s) that prevent a decision on the claim; and (5) a description of any additional information that the claimant needs to submit.

(b) Appeal Procedures.

(i) Request for Review. If the claimant’s claim is denied, the claimant (or his or her authorized representative) may apply in writing to the Plan Administrator for a review of the decision denying the claim. The Plan Administrator shall afford the claimant a full and fair review of the decision denying the claim and, if so requested, shall: (1) provide the claimant with the opportunity to submit written comments, documents, records, and other information relating to the claim for benefits; (2) provide that the claimant shall be provided, upon request and free of charge, reasonable access to, and copies of all documents, records and other information (other than documents, records and other information that is legally privileged) relevant to the claimant’s claim for benefits; and (3) provide for a review that takes into account all comments, documents, records and other information submitted by the claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

(ii) Determination of Appeal. If the claimant’s appeal is subsequently denied by the Plan Administrator, in whole or in part, then the claimant shall be furnished with a denial notice that shall contain the following: (1) the specific reason(s) for the denial; (2) reference to the specific Plan provision(s) on which the denial is based; and (3) an explanation of the Plan’s review procedures and the time limits applicable to such procedures including a statement of the claimant’s right to bring a civil action under ERISA Section 502(a) following the denial on review.

(iii) Timing of Decision on Review. The decision on review shall be issued within sixty (60) days following the request for review. The period for decision may, however, be extended up to one hundred and twenty (120) days after such receipt if the Plan

Page 11 of 17

Administrator determines that special circumstances require extension. In the case of an extension, notice of the extension shall be furnished to the claimant (or his or her authorized representative) prior to the expiration of the initial sixty (60) day period. In no event shall such extension exceed a period of sixty (60) days from the end of such initial period. The extension notice shall indicate the special circumstances requiring the extension of time and the date by which the Plan Administrator expects to render the benefits determination.

(c) Procedural Requirements. No Participant, Beneficiary, or other claimant may bring a lawsuit to recover benefits under the Plan until he or she has exhausted the internal administrative process described above. No legal action may be commenced at all unless commenced no later than one (1) year following the issuance of a final decision on the claim for benefits, or the expiration of the appeal decision period if no decision is issued. This one-year statute of limitations on suits for all Severance Benefits available under the Plan shall apply in any forum where such a suit is initiated.

ARTICLE 7

MISCELLANEOUS PROVISIONS

7.1 Tax Withholding. All payments made or benefits provided under the Plan shall be subject to withholding for any applicable taxes or other amounts which federal, state or local law requires the Company to withhold. The Company’s determination of the type and amount of taxes to be withheld from any payment or benefit shall be final and binding on all persons having or claiming to have an interest in this Plan.

7.2 Section 409A Compliance.

(a) Notwithstanding any other provisions to the contrary, no payments or any benefits will be provided under the Plan earlier than permitted by Section 409A of the Code, or later than the latest day permitted in order to avoid taxation under such section. Further, the Plan Administrator, in its sole discretion may amend or modify the Plan in any manner to provide for the application and effects of Section 409A of the Code its related Treasury regulations, and any related regulatory or administrative guidance issued by the Internal Revenue Service.

(b) Deferred Commencement Date for Specified Employees. Notwithstanding any provision to the contrary in the Plan, to the extent required to avoid a prohibited distribution under Section 409(A)(2) of the Code, no Severance Benefits, payments, or other benefits to which a Participant becomes entitled under the Plan shall be made prior to the earlier of (i) the first business day following the expiration of the six (6)-month period measured from the date of the Participant’s “separation from service” (as defined under Code Section 409(A) and its related Treasury regulations) or (ii) the death of the Participant if he or she is at the time a “specified employee” within the meaning of that term under Section 409A of the Code. Upon the expiration of the delay period required by Section 409A of the Code, all payments and benefits deferred under this paragraph otherwise payable in the form of a salary continuation shall commence to be paid by the end of the first month following the expiration of the delay period. For the avoidance of doubt, that portion of the payments provided under this Plan that do not exceed the Code Section 409A Limit (as defined below) and which qualify as

Page 12 of 17

“separation pay” under Treasury regulation Section 1.409A-1(b)(9)(iii), shall be paid or commence to be paid on the date originally specified for such payment. For purposes of this Plan, “Code Section 409A Limit” means the lesser of two (2) times: (i) the Participant’s annual compensation paid during the Company’s taxable year preceding the taxable year in which the Participant is terminated, as determined under Treasury regulation Section 1.409A-1(b)(9)(iii)(A)(1) and any related Internal Revenue Service guidance; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which such termination occurs. In the event of a Participant’s death, any amounts delayed under this Section 7.2(b) shall be paid to the personal representative of the Participant’s estate as soon as practicable but in all events within sixty (60) days after the date of his or her death. For purposes of determining the individuals who will be “specified employees” under the Plan, the identification date shall be December 31 of each calendar year.

7.3 Waiver of Other Benefits; Non-Duplication. By agreeing to commence participation in the Plan, each Eligible Executive who would otherwise be entitled to receive severance or similar benefits in connection with a Termination under another employee benefit plan, employment agreement, offer letter, or other agreement or understanding with the Company agrees to irrevocably waive any such entitlement in full. Such waiver shall be in writing in such form as may reasonably be specified by the Plan Administrator (including in a Participation Agreement) and shall be filed with the Plan Administrator in accordance with such rules and procedures as it may reasonably establish. The Plan is intended to supersede, and not to duplicate, the provisions of the Sourcefire, Inc. Executive Retention Plan (“Retention Plan”) in any case in which an Eligible Executive would otherwise be entitled to severance or related benefits under both this Plan and the Retention Plan arising out of the Eligible Executive’s Qualifying Termination. In the event that an Eligible Executive becomes entitled to receive Severance Benefits under this Plan and any such benefits duplicate a benefit that would otherwise be provided under any other plan, program, arrangement or agreement, including without limitation, the Retention Plan, as a result of the Eligible Executive’s Termination (irrespective of whether such Termination constitutes a Qualifying Termination), then the Eligible Executive shall be entitled to receive only the Severance Benefits available under the Plan and in no event shall such Eligible Executive be entitled to receive any duplicative benefits. The Plan Administrator shall determine in its sole and exclusive judgment and discretion whether and in what manner the provisions of this Section 7.3 shall apply.

7.4 Coordination with Mandated Benefits. To the extent that any federal, state or local law, including, without limitation, so-called plant closing laws, requires the Company to give advance notice or make payment of any kind to a Participant because of his or her involuntary termination due to a layoff, reduction in force, plant or facility closing, sale of business, change of control, or any other similar event or reason, the benefits provided under this Plan shall either be reduced or eliminated accordingly. The benefits provided under this Plan are intended to satisfy any and all statutory obligations that may arise out of any Participant’s involuntary termination for the foregoing reasons, and the Plan Administrator shall so construe and implement the terms of the Plan it its sole discretion. Included in the scope of the foregoing, if a Participant receives notice from the Company pursuant to the Workers Adjustment and Retraining Notification (“WARN”) Act, and remains employed during the WARN notice period, then the Severance Benefits for which the Participant is eligible under this Plan will be reduced

Page 13 of 17

by the amount of the Severance Benefits he or she receives during the applicable WARN notice period.

7.5 Non-Assignability. In no event may any Participant, Eligible Executive, or other current or former employee of the Company or any of its subsidiaries or affiliates sell, transfer, anticipate, assign or otherwise dispose of any right or interest under the Plan. At no time will any such right or interest be subject to the claims of creditors nor liable to attachment, execution or other legal process.

7.6 Facility of Payment. If any person entitled to payments under this Plan is, in the opinion of the Plan Administrator or its designee, incapacitated and unable to use such payments in his or her own best interest, the Plan Administrator or its designee may direct that payments (or any portion) be made to that person’s legal guardian or conservator, or that person’s spouse, as an alternative to payment to the person unable to use the payments. The Plan Administrator or its designee will have no obligation to supervise the use of such payments, and court-appointed guardianship or conservatorship may be required.

7.7 Assumption by Successor. The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and to agree to perform the obligations under this Plan in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place; provided, however, that no such assumption shall relieve the Company of its obligations hereunder. As used in this Section 7.7, the “Company” shall include the Company and any successor to its business and/or assets which assumes and agrees to perform the obligations arising under this Plan by operation of law or otherwise.

7.8 Effect on Other Plans. Participation in this Plan has no effect on the rights of any Participant under any other employee benefit plan sponsored by the Company such as any pension or profit-sharing, medical, dental or hospitalization, life insurance, AD&D, bonus, incentive compensation, or vacation pay plan. Employee rights under those benefit plans are governed solely by their terms, and Participants should review those plans to ascertain their rights under them.

7.9 Voluntary Plan/No Alteration of Employment-At-Will Status. The adoption of the Plan is purely voluntary on the part of the Company and the Plan shall not be deemed to constitute a contract between the Company and any employee or other person not in the employ of the Company, or to be a consideration for, or an inducement or condition of, the employment of any employee or other person. This Plan does not alter, and should not be considered as altering, the at-will employment relationship between the Company and its employees, under which an employee of the Company is free to terminate his/her employment relationship with the Company at any time for any reason, and the Company may terminate its employment relationship with an employee at any time for any lawful reason.

7.10 Source of Payments. All Severance Benefits will be paid in cash from the general funds of the Company; no separate fund will be established under the Plan; and the Plan xxxx

Xxxx 14 of 17

have no assets. No right of any person to receive any payment under the Plan will be any greater than the right of any other general unsecured creditor of the Company.

7.11 No Rights Created or Accrued. No Participant shall have any vested rights under the Plan and nothing herein shall be construed as giving any Participant any nonforfeitable or vested rights to any benefits hereunder. Nothing in the Plan shall be construed as giving to a Participant a right to receive any benefit other than the benefits specifically provided under the terms of the Plan. No benefits shall be deemed to accrue under the Plan at any time except the time at which they become payable under the Plan, and no right to a benefit under the Plan shall be deemed to vest prior to a Participant’s Termination Date.

7.12 Controlling Law. Except as may be otherwise provided in the contracts incorporated by reference into the Plan, the provisions of the Plan shall be construed, administered and enforced according to ERISA and, to the extent not preempted, by the laws of the State of Maryland. If any provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if such illegal and invalid provisions had never been set forth in the Plan.

STATEMENT OF ERISA RIGHTS

The Employee Retirement Income Security Act of 1974 (“ERISA”) was enacted to help assure that all employer-sponsored group benefits programs conform to standards set by Congress. The Sourcefire, Inc. Executive Change in Control Severance Plan is covered by XXXXX and an employee who is a participant in this Plan is entitled to certain rights and protections. XXXXX provides that all Plan participants shall be entitled to examine, without charge, at the Company’s business office, all Plan documents and copies of all documents filed by the Plan with the U.S. Department of Labor, such as detailed annual reports and to obtain copies of all Plan documents and other Plan information, if applicable, upon written request to the Company. The Company may make a reasonable charge for the copies. The Company is required by law to furnish each participant with a copy of this summary annual report, if applicable.

In addition to creating rights for Plan participants, XXXXX also sets forth certain duties for the people who are responsible for the operation of the Plan. The people who operate the Plan are called “fiduciaries” of the Plan. They have a duty to operate the Plan prudently and in the best interests of you and other Plan participants and beneficiaries. No one, including your employer, or any other person, may fire you or otherwise discriminate against you to prevent you from either obtaining any Plan benefit or exercising your rights under ERISA. However, neither the existence of the Plan nor this summary plan description constitutes an employment contract or affects the right of the Company to lawfully terminate your employment.

If your claim for a Plan benefit is denied in whole or in part, you must receive a written explanation of the reasons for the denial. You have the right to have the Plan Administrator review and reconsider your claim.

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request materials from the Plan and do not receive them within 30 days, you may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 per day until you receive the materials (unless the materials were not sent because of reasons beyond the control of the Plan Administrator). If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or federal court. If it should happen that Plan fiduciaries do not fulfill their responsibilities under ERISA, or if you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees (for example, if the court finds your claim is frivolous).

If you have any questions about the Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Company, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 000 Xxxxxxxxxxxx Xxxxxx X.X., Xxxxxxxxxx, X.X. 00000. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

Exhibit A — Form of Separation and Release Agreement

THIS AGREEMENT AND GENERAL RELEASE (the “Release Agreement”) is made and entered into on ___________, 20___, by and between _______________ (the “Participant”) and SOURCEFIRE, INC., a Delaware corporation (the “Company”).

Exhibit B — Form of Notice of Eligibility/Participation Agreement

Dear [Eligible Executive]:

This letter relates to the Sourcefire, Inc. Executive Change in Control Severance Plan (the “Plan”) that we, Sourcefire, Inc. have adopted.

Through this letter, you are being offered the opportunity to become a participant in the Plan and thereby to be eligible to receive the voluntary severance benefits described below in the event of your “qualifying termination.” A copy of the Plan is attached to this letter. You should read it carefully and become comfortable with its terms and conditions, and those set forth below. In order to commence participation in the Plan, you must execute this letter and return it to the Company. By executing this letter, you will be establishing a “Participation Agreement” within the meaning of the Plan, and you will thereby be acknowledging and agreeing to the following provisions:

	•		that you have received and reviewed a copy of the Plan;

	•		that terms not defined in this letter but beginning with initial capital letters shall have the meaning assigned to them in the Plan;

	•		that your participation in the Plan requires that you agree irrevocably and voluntarily to the terms of the Plan and the terms set forth below; and

	•		that you have had the opportunity to carefully evaluate this opportunity, and desire to participate in the Plan according to the terms and conditions set forth herein.

Subject to the foregoing, we invite you to become a “Participant” in the Plan. Your participation in the Plan will be effective upon your signing and returning this letter agreement to the Company within thirty (30) days of your receipt of this letter agreement. Capitalized terms used in this participation agreement but not otherwise defined will have the meaning set forth in the Plan.

NOW, THEREFORE, you and the Company (hereinafter referred to as “the parties”) hereby AGREE as follows:

1. If while the Plan and this Participation Agreement are in effect, you become entitled to a Severance Benefit in accordance with 4.2 of the Plan as a result of your Qualifying Termination, then the following will be applicable.

(a) Salary Continuation Benefits. Your cash Severance Benefits will be paid in the form of salary continuation, at the time and the manner provided in Section 4.3(a) of the Plan. The Severance Period used to determine the amount and duration of your salary

Exhibit B

Page 1 of 4

continuation benefits will be twelve (12) months. Your salary continuation benefits will be determined based on your Base Salary, as provided in Section 4.3(a) of the Plan.

(b) COBRA Subsidy. You and your COBRA qualifying beneficiaries will be entitled to COBRA continuation coverage at the active employee rates in effect on your Termination Date for the duration of your Severance Period. Thereafter, you will be entitled to continuation coverage at your own expense at the COBRA premium rates then in effect and only to the extent you and/or your COBRA qualifying beneficiaries remain eligible for COBRA coverage at that time.

(c) Acceleration of Equity Awards. Your outstanding and unvested stock options will accelerate and become vested, and the restrictions applicable to your outstanding restricted stock award(s) will lapse and become vested, as follows: (i) the vesting of your outstanding and unvested stock options will accelerate and become fully vested; and (ii) the restrictions applicable to each of your outstanding awards of restricted stock and restricted stock units will lapse and become vested by fifty percent (50%) of the total shares originally subject to such award; provided, however, that in the event that as of your Date of Termination there are not a sufficient number of shares subject to restrictions (with respect to such award) to allow for the lapse described above, either in full or in part, then, the restrictions shall lapse (with respect to such award), as necessary to give effect to the restriction lapse described in this subsection 1(c), up to the number of restricted shares or restricted stock units then subject to such award.

2. Loss of Eligibility. Even if you are otherwise eligible to receive the Severance Benefits described in Paragraph 1 above, you will forfeit your entitlement to those benefits to the extent described below in the following circumstances.

	•		Failure to Provide an Effective Release. As a condition of receiving any Severance Benefits pursuant to the Plan and this Participation Agreement, you must execute and not revoke a Release supplied by the Company. Payments of Severance Benefits will not commence until your Release has become effective and irrevocable.

	•		Alternative Employment. If, subsequent to the commencement of Severance Benefits, you secure alternative employment, your right to Company-subsidized COBRA premiums will end but, subject to the terms of the Plan and your Notice of Eligibility, you will remain eligible to receive salary continuation benefits.

	•		Violation of Certain Obligations. If, subsequent to the commencement of Severance Benefits, you violate the continuing non-disclosure, non-competition, or non-solicitation provisions applicable to you under an agreement with the Company, your right to continuing salary continuation benefits and Company-subsidized COBRA premiums will end, and the Company will be entitled to recover any prior payments made to you and to exercise any other rights and remedies it may have under the terms of the applicable agreement.

If your employment with the Company ends in circumstances that are not a Qualifying Termination (for example, you are terminated by the Company for Cause, you voluntarily resign without Good Reason, or your termination occurs more than twelve months following a Change in Control), you will not be entitled to receive any Severance Benefits under the Plan.

3. Waiver of Other Benefits; Non-Duplication. As a condition of and in consideration of your becoming eligible to receive the Severance Benefits provided under the terms and conditions of the Plan and this Participation Agreement, you agree to waive any and all rights, benefits, and privileges to severance or similar benefits that you might otherwise be entitled to receive under any other oral or written plan, employment agreement or arrangement (including, without limitation, your existing employment agreement or offer letter). You understand that this waiver is irrevocable, and that this Participation Agreement and the Plan set forth the entire agreement between us with respect to any subject matter covered herein. The Plan is intended to supersede, and not to duplicate, the provisions of the Sourcefire, Inc. Executive Retention Plan (“Retention Plan”) in any case in which you would otherwise be entitled to severance or related benefits under both this Plan and the Retention Plan arising out of your Qualifying Termination. For purposes of clarification, your waiver will not generally preclude you from eligibility to participate in the Retention Plan, but if you become eligible to receive Severance Benefits as a result of your Qualifying Termination, you will forfeit any “retention benefits” you might otherwise be entitled to receive under the Retention Plan. In no event will you be entitled to receive benefits under both the Plan and the Retention Plan as a result of your Termination.

4. Tax Compliance. You understand and acknowledge that you are ultimately liable and responsible for all taxes owed in connection with any Severance Benefits you may receive under the Plan, regardless of any action the Company takes with respect to any tax withholding obligations that arise in connection with these benefits. The Company makes no representation or undertaking regarding the treatment of any tax withholding in connection with your Severance Benefits. While the Company intends to operate the Plan in a manner that avoids the limitations imposed by Section 409A of the Internal Revenue Code, the Company makes no representation that the Plan will, in fact, avoid these limitations or will comply with Section 409A to the extent it becomes applicable. The Company makes no undertaking to prevent Section 409A from applying to this Plan or any Severance Benefits made under it or to mitigate the effects of such provision on any payments made pursuant to this Plan. You are encouraged to consult a tax adviser regarding the potential tax and other implications of participation in the Plan in light of your own personal circumstances.

You understand and acknowledge that the Company in the exercise of its sole discretion and without your consent, may amend or modify this letter agreement and the Plan in any manner and delay the payment of amounts pursuant to this letter agreement and the Plan to the minimum extent necessary to meet the requirements of Section 409A as amplified by any Treasury regulations or guidance from the Internal Revenue Service as the Company deems appropriate or advisable

5. Severability of Provisions. If any provision of the Plan, or of this Participation Agreement, is determined to be unlawful, invalid or unenforceable, such provision shall be deemed severed from the Plan or this Participation Agreement, respectively, but every other provision of the Plan or of this Participation Agreement shall remain in full force and effect. In substitution for any provision of the Plan or this Participation Agreement being held unlawful, invalid or unenforceable, there shall be substituted a provision of similar import reflecting the original intent of the parties hereto to the fullest extent permissible under law.

6. Acknowledgment. You recognize and agree that your execution of this Participation Agreement results in your enrollment and participation in the Plan, that you agree to be bound by the terms and conditions of the Plan and this Participation Agreement, and that you understand that this Participation Agreement may not be amended or modified except pursuant to Section 6.2 of the Plan.
