This Assignment Letter confirms our mutual understanding of the terms and conditions applicable to

describes the provisions applicable to your temporary international assignment. It contains both
policy and procedural guidelines for compensation, benefits, and allowances related to your
assignment. By signature below, you acknowledge and agree to adhere to the terms and conditions of
the assignment. Any deviation from the components of the Assignment Letter must be agreed to in
writing and attached to the Assignment Letter as an addendum.

The following provisions will apply during your assignment:

	 	1.	 	Position Title: President of PTI Group, Inc. and Director of The Mac Services
Group, Inc.
	 
	 	2.	 	Host Location: Sydney, Australia
	 
	 	3.	 	Home Location: Edmonton, Canada
	 
	 	4.	 	Effective Date of Assignment: May 3, 2011
	 
	 	 	 	This is contingent upon obtaining any and all medical clearances and visas and/or employment
passes, as required by the Australian government. The Company will pay such reasonable
expenses and official fees for your passport or visa in connection with your relocation to
Australia.
	 
	 	5.	 	Duration of Assignment: 12 months
	 
	 	 	 	International assignments are temporary in nature. The initial term of this agreement is
twelve (12) months. At the end of the initial term, a review process will take place to
determine if there is a need to extend the assignment for a longer duration. However, the
total length of your assignment will not exceed two (2) years.

 

	 	 	 	The terms and conditions outlined in this letter will be in effect only for the initial term
of this agreement. Upon completion of your assignment, you will be required to return to
your home country Canada.
	 
	 	6.	 	Annual Base Salary:
	 
	 	 	 	Base salary is calculated on an annual basis. It is the basis for calculating assignment
related allowances, premiums, supplementary payments and deductions. These compensation
components may be paid in Home Country currency (Canadian dollars, with payments deposited
directly into an established bank account or the compensation components may be calculated
in Home Country currency, but paid in Host Country currency (Australian dollars. In
situations where legal and/or tax statutes necessitate local payment of cash compensation, a
portion of pay may be delivered in local currency.
	 
	 	7.	 	Benefits
	 
	 	 	 	You will be provided health, welfare, retirement plan and workers compensation benefits that
are comparable to your current Home Country plan. The Company’s Global Benefits Plan will
also be provided to ensure supplemental coverage for the duration of the assignment.
	 
	 	8.	 	Goods and Services Differential (“GSD”) / Cost of Living Adjustment (“COLA”)
	 
	 	 	 	A Goods and Services payment (“GSD”) will be provided when the cost-of-living is determined
to be higher in the Host Country than in your Home Country. This amount is a separately
identified payment of your remuneration. It will be provided on a monthly basis deposited
directly into your bank account.
	 
	 	 	 	During the course of your assignment the GSD will be reviewed twice a year and/or adjusted
in response to changing economic factors (e.g. exchange rate fluctuation, relative inflation
between the Home and Host Country and changes in salary or family size while on assignment).
It is important to note that the allowance may increase or decrease depending on these
factors.
	 
	 	 	 	You will receive a living away from home allowance (“LAFHA”) — Food Component as part of
the GSD, of $810 per month to compensate you for the additional food costs. The amount of
compensation for additional food costs has been determined after taking into account your
normal food consumption expenditure and the allowance is to compensate you for the costs in
addition to that estimated amount. The amount of the allowance will be reviewed at the start
of each fiscal tax year, i.e. 1 April.
	 
	 	9.	 	Housing 
	 
	 	 	 	The Company will pay for furnished rental housing in the Host Country            within
established guidelines. The Company will advise a housing budget entitlement based on
pre-established guidelines and in most cases the Company will own the lease and pay the
actual rent directly. You will not be required to contribute to this cost. This is on the
basis that you are incurring additional accommodation costs as a result of your relocation.
In the event that your circumstances change and you no longer intend to return to your usual
place of residence you will be required to notify the Company as soon as possible.

EMPLOYEE DECLARATIONS

 

	 	 	 	In order to be eligible to receive the benefits described above, upon commencement of your
assignment, and annually thereafter, you are required to complete an annual declaration for
the purposes of The Mac Services Group, Inc. fringe benefits tax return. This declaration
should be completed on or before 30 April each year in respect of the 12 month period (or
elapsed period of employment if shorter) ending on the previous 31 March.

	 	12.	 	Income Tax Equalization
	 
	 	 	 	In view of the additional personal income taxes arising from your international assignment,
the Company follows a policy of “tax equalization.” The objective of this approach is to
hold you responsible for the amount of Home Country taxes you would have paid had you not
gone on international assignment and ensure you do not pay more in taxes than you would have
as a result of the assignment. The Company will reimburse you for all actual Host Country
and residual Home Country personal income taxes paid on Company-earned income. As your
contribution, the Company will deduct from your base salary a hypothetical income tax, based
on typical Federal and Provincial (if applicable) tax calculated based on your salary and
family size. Similarly to ordinary tax returns, a tax true-up at the end of the year will
apply when your tax returns are completed. It is the Company’s intent to maintain your
participation in Home Country social insurance and other applicable Home Country benefits
programs, to the extent possible.
	 
	 	 	 	The Company will designate an external tax consultant to assist in the preparation and
processing of your Host and Home country tax returns at the Company’s expense. In the event
that penalties and/or interest charges are imposed because your tax returns are not filed in
a timely fashion, you will be responsible for the charges, unless the Company can confirm
that you have made bona fide efforts to have your returns filed on time.
	 
	 	 	 	An initial tax briefing will be conducted by the Company’s tax provider to provide you with
more detailed information related to the Company’s tax equalization program and answer any
questions you have related to the Company’s tax policy/program.

ADOPTION AND NATURE OF PLAN

     1.1 Adoption of Plan. The Sourcefire, Inc. Executive Retention Plan (the
“Plan”) is hereby established, effective as of March 31, 2008, as amended effective as of
March 31, 2011, to provide certain retention incentives 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 ERISA. 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.

Participant ceases to be categorized as an employee on the payroll system of the Company as a
result of a Qualifying Termination or otherwise. For purposes of Retention Benefits or similar
benefits under the Plan that are not exempt from the provisions of Code Section 409A, a
Participant’s Termination Date will be the date on which he or she incurs a “separation from
service” (within the meaning of Section 409A(a)(2)(A)(i) of the Code and its related regulatory
and administrative guidance), as determined by the Plan Administrator in its sole discretion. The
last day of a Participant’s active employment with the Company shall be considered his or her
“termination date” for purposes of the Company’s other employee benefit plans, unless otherwise
provided by such plans. For purposes of a Participant’s eligibility for continued health benefits
under COBRA, the COBRA eligibility period shall run from the Participant’s Termination Date,
except as otherwise provided by applicable law.

     2.19 “Termination of Employment”, “Terminated”, or “Terminates” means
a Participant’s (i) separation from service with the Company, (ii) refusal or failure to return to
work within three (3) working days after the date requested by the Company which results in a
separation from service with the Company, or (iii) failure to return to work at the conclusion of
a leave of absence. Notwithstanding the foregoing, a Participant will not be deemed to have
experienced a Termination of Employment while absent on military leave, sick leave, or other bona
fide leave of absence if the period of such leave does not exceed six (6) months, or if longer,
the period during which the Participant’s right to reemployment is guaranteed by statute or
contract. If the period of leave exceeds six (6) months, and the Participant’s right to
reemployment is not guaranteed by statute or contract, he or she will be deemed to have
experienced a Termination of Employment as of the first day immediately following the end of such
six-month period. Notwithstanding the foregoing, for purposes of the Plan, no payments of amounts
subject to Section 409A of the Code shall be triggered by any Termination of Employment that is
not considered to constitute a “separation from service” within the meaning of Section
409A(a)(2)(A)(i) of the Code and its related regulatory and administrative guidance, as determined
by the Plan Administrator in its sole discretion.

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 Retention 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

Page 4 of 15

 

submitted an executed Participation Agreement to the Plan Administrator will be referred to as a
“Participant.”

ARTICLE 4

RETENTION BENEFITS

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

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

Page 5 of 15

 

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.

     4.4 Loss of Eligibility. A Participant who is otherwise eligible to receive
Retention 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 Retention Benefits
otherwise available under the Plan.

          (b) Alternative Employment. A Participant who secures alternative employment during
the Benefit 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 Retention 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 Retention Benefits and it will have the right
to seek repayment of any such Retention Benefits that have already been made, without
prejudice to any other remedies that may be available to the Company.

Page 6 of 15

 

          (d) Non-Qualifying Termination. A Participant whose Termination of Employment does
not constitute a Qualifying Termination will not be entitled to any Retention 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 Retention
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 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

Page 7 of 15

 

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, modification,
or termination shall be effective with respect to the availability, amount, or timing of payment
of any Retention 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 Retention
Benefits with respect to 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. 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 Retention Benefit or similar benefit 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 Retention 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.

Page 8 of 15

 

          (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 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)

Page 9 of 15

 

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 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 Retention 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

Page 10 of 15

 

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 Retention Benefits or other payments or 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 “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,
retention, or similar benefits in connection with a Termination of Employment 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. Notwithstanding the foregoing, if an
Eligible Executive becomes entitled to receive severance benefits under the Sourcefire, Inc.
Executive Change in Control Severance Plan (the “Executive Plan”) as a result of his or
her “qualifying termination” (as defined in the Executive Plan), any such waiver shall not
preclude the Eligible Executive from receiving such severance benefits thereunder, but in such
event, the Eligible Executive shall forfeit entitlement to any Retention Benefits that might have
otherwise been payable under the Plan. In no event will any Eligible
Executive be entitled to receive benefits or payments under both the Executive Plan and this
Plan as a result of his or her Termination of Employment.

Page 11 of 15

 

     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 Retention Benefits for which the Participant is eligible under this Plan will be
reduced by the amount of the Retention 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.

Page 12 of 15

 

     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 Retention 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
will 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 Retention Plan is covered by ERISA and an employee who is a
participant in this Plan is entitled to certain rights and protections. ERISA 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, ERISA 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, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also obtain
certain publications about your rights and responsibilities under ERISA by calling the publications
hotline of the Employee Benefits Security Administration.

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

     WHEREAS, the Participant’s employment with the Company terminated effective as of
______________, 200__ (the “Date of Termination”);

     WHEREAS, the Participant is a participant in the Sourcefire, Inc. Executive Retention Plan
(the “Plan”), pursuant to which Participant is eligible to receive retention benefits,
contingent upon certain conditions that are outlined in the Plan; and

     WHEREAS, one such condition under the Plan and that certain Participation Agreement dated
__________, 200_ between Participant and the Company (the “Participation Agreement”) to
receiving the severance benefits is Participant’s execution, return and non-revocation of this
Release Agreement.

     NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements set forth in
this Release Agreement, the sufficiency of which the parties acknowledge, it is agreed as follows:

     2. Notwithstanding anything to the contrary in this Release Agreement, if on the date of the

within the meaning of Code Section 409A, any payments and benefits that otherwise would be due
under Section 1 on account of the Participant’s Separation from Service and within the first six
(6) months following the Participant’s Separation from Service, shall instead be paid in a lump sum
on the first business day of the seventh (7th) month following the Participant’s
Separation from Service (but only to the extent that such payments or benefits constitute
“deferrals of compensation,” within the meaning of United States Treasury Regulation (“Treasury
Regulation”) Section 1.409A-1(b) and after application of the exemptions provided in Treasury
Regulation Sections 1.409A-1(b)(4) and 1.409A-1(b)(9)). Each payment or benefit under Section 1

the meaning set forth in Treasury Regulation Section 1.409A-1(h)(1)(i).

     3. The parties agree that the payments described in the Plan, Participation Agreement and this
Release Agreement are in full, final and complete settlement of all claims the Participant may have
against the Company and its past and present affiliates, officers, directors,

owners, employees, agents, successors and assigns. The parties agree that the Participant
would not otherwise be entitled to these payments but for his promises in this Release Agreement.

     4. Nothing in this Release Agreement shall be construed as an admission of liability by the
Company or its past and present affiliates, officers, directors, owners, employees or agents, and
the Company specifically disclaims liability to or wrongful treatment of the Participant on the
part of itself and its past and present affiliates, officers, directors, owners, employees and
agents.

     5. The Participant represents that he has not filed any complaints or charges against the
Company with the Equal Employment Opportunity Commission or with any other federal, state, local,
foreign or other agency or court, and covenants that he will not seek to recover on any claim
released in this Release Agreement.

     6. In exchange for the payments and other consideration under this Release Agreement to which
Participant would not otherwise be entitled, subject to applicable law, Participant hereby releases
and forever discharges the Company and its past and present affiliates, directors, officers,
owners, employees and agents, as well as its successors and assigns (collectively, the
“Releasees”), from any and all claims, liabilities, damages, demands and causes of action
or liabilities of any nature or kind, whether now known or unknown, arising out of or in any way
connected with the Participant’s employment with the Company or its affiliates or the termination
of that employment; provided, however, that nothing in this Release Agreement shall (i) waive any
rights or claims of the Participant that arise after this Release Agreement becomes effective, (ii)
impair or preclude his right to take action to enforce the terms of this Release Agreement, (iii)
impair the Participant’s vested rights under any tax-qualified retirement plan

Sourcefire, Inc. Executive Retention Plan

Exhibit B — Form of Notice of Eligibility/Participation Agreement

Dear [Eligible Executive]:

This letter relates to the Sourcefire, Inc. Executive Retention 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
Retention 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 Retention 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 Benefit Period used to determine the amount and duration of your salary continuation

Exhibit B
Page 1 of 4

 

benefits will be six (6) 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 Benefit 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.

     2. Loss of Eligibility. Even if you are otherwise eligible to receive the Retention
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 Retention Benefits pursuant to the Plan and this Participation Agreement, you
must execute and not revoke a Release supplied by the Company. Payments of
Retention Benefits will not commence until your Release has become effective and
irrevocable.
	 
	 	•	 	Alternative Employment. If, subsequent to the commencement of Retention
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
Retention 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.
	 
	 	•	 	Non-Qualifying Termination. 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 or you voluntarily resign without Good Reason),
you will not be entitled to receive any Retention 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 Retention 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

Exhibit B
Page 2 of 4

 

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.
Notwithstanding the foregoing, if you are a participant in the Sourcefire, Inc. Executive Change in
Control Severance Plan (the “Executive Plan”) and you become eligible to receive severance
benefits thereunder as a result of your “qualifying termination” (as defined in the Executive
Plan), your waiver will not preclude your receipt of such severance benefits, but you will forfeit
any Retention Benefits you might otherwise be entitled to receive under the Plan as a result of
your Termination. In no event will you be entitled to receive benefits under both the Plan and the
Executive 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 Retention 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 Retention 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 Retention
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.
