with the following schedule:



     25% of the Shares subject to the Option shall vest twelve months after the Vesting

return to service to the Company or a Related Entity. The Vesting Schedule of the Option

     IN WITNESS WHEREOF, the Company and the Grantee have executed this Notice and agree that the

THE GRANTEE ACKNOWLEDGES AND AGREES THAT THE SHARES SUBJECT TO THE OPTION SHALL VEST, IF AT ALL,

BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER). THE GRANTEE FURTHER ACKNOWLEDGES AND
AGREES THAT NOTHING IN THIS NOTICE, THE OPTION AGREEMENT, OR THE PLAN SHALL CONFER UPON THE GRANTEE
ANY RIGHT WITH RESPECT TO FUTURE AWARDS OR CONTINUATION OF THE GRANTEE’S CONTINUOUS SERVICE, NOR
SHALL IT INTERFERE IN ANY WAY WITH THE GRANTEE’S RIGHT OR THE RIGHT OF THE COMPANY OR RELATED
ENTITY TO WHICH THE GRANTEE PROVIDES SERVICES TO TERMINATE THE GRANTEE’S CONTINUOUS SERVICE, WITH

Option subject to all of the terms and provisions hereof and thereof. The Grantee has reviewed

2007 STOCK INCENTIVE PLAN




STOCK OPTION AWARD AGREEMENT




     1. Grant of Option. Sourcefire, Inc., a Delaware corporation (the “Company”), hereby
grants to the Grantee (the “Grantee”) named in the Notice of Stock Option Award (the “Notice”), an
option (the “Option”) to purchase the Total Number of Shares of Common Stock subject to the Option
(the “Shares”) set forth in the Notice, at the Exercise Price per Share set forth in the Notice
(the “Exercise Price”) subject to the terms and provisions of the Notice, this Stock Option Award
Agreement (the “Option Agreement”) and the Company’s 2007 Stock Incentive Plan, as amended from
time to time (the “Plan”), which are incorporated herein by reference. Unless otherwise defined
herein, the terms defined in the Plan shall have the same defined meanings in this Option
Agreement.



     If designated in the Notice as an Incentive Stock Option, the Option is intended to qualify as
an Incentive Stock Option as defined in Section 422 of the Code. However, notwithstanding such
designation, the Option will qualify as an Incentive Stock Option under the Code only to the extent
the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. The $100,000
limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market Value of
the Shares subject to options designated as Incentive Stock Options which become exercisable for
the first time by the Grantee during any calendar year (under all plans of the Company or any
Parent or Subsidiary of the Company). For purposes of this calculation, Incentive Stock Options
shall be taken into account in the order in which they were granted, and the Fair Market Value of
the shares subject to such options shall be determined as of the grant date of the relevant option.



     2. Exercise of Option.



          (a) Right to Exercise. The Option shall be exercisable during its term in accordance
with the Vesting Schedule set out in the Notice and with the applicable provisions of the Plan and
this Option Agreement. The Option shall be subject to the provisions of Section 11 of the Plan
relating to the exercisability or termination of the Option in the event of a Corporate Transaction
or Change in Control. The Grantee shall be subject to reasonable limitations on the number of
requested exercises during any monthly or weekly period as determined by the Administrator. In no
event shall the Company issue fractional Shares.




          (b) Method of Exercise. The Option shall be exercisable by delivery of an exercise
notice (a form of which is attached as Exhibit A) or by such other procedure as specified from time
to time by the Administrator which shall state the election to exercise the Option, the whole
number of Shares in respect of which the Option is being exercised, and such other provisions as
may be required by the Administrator. The exercise notice shall be delivered in person, by
certified mail, or by such other method (including electronic transmission) as determined from time
to time by the Administrator to the Company accompanied by payment
of


1









 







the Exercise Price and all applicable income and employment taxes required to be withheld.
The Option shall be deemed to be exercised upon receipt by the Company of such notice accompanied
by the Exercise Price all applicable withholding taxes, which, to the extent selected, shall be
deemed to be satisfied by use of the broker-dealer sale and remittance procedure to pay the
Exercise Price provided in Section 3(d), below to the extent such procedure is available to the
Grantee at the time of exercise and such an exercise would not violate any Applicable Law.




          (c) Taxes. No Shares will be delivered to the Grantee or other person pursuant to the
exercise of the Option until the Grantee or other person has made arrangements acceptable to the
Administrator for the satisfaction of applicable income tax and employment tax withholding
obligations, including, without limitation, such other tax obligations of the Grantee incident to
the receipt of Shares. Upon exercise of the Option, the Company or the Grantee’s employer may
offset or withhold (from any amount owed by the Company or the Grantee’s employer to the Grantee)
or collect from the Grantee or other person an amount sufficient to satisfy such tax withholding
obligations.




     3. Method of Payment. Payment of the Exercise Price shall be made by any of the
following, or a combination thereof, at the election of the Grantee; provided, however, that such
exercise method does not then violate any Applicable Law:



          (a) cash;




          (b) check;




          (c) surrender of Shares or delivery of a properly executed form of attestation of ownership of
Shares as the Administrator may require which have a Fair Market Value on the date of surrender or
attestation equal to the aggregate Exercise Price of the Shares as to which the Option is being
exercised; or




          (d) payment through a broker-dealer sale and remittance procedure pursuant to which the
Grantee (i) shall provide written instructions to a Company-designated brokerage firm to effect the
immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to
cover the aggregate exercise price payable for the purchased Shares and (ii) shall provide written
directives to the Company to deliver the certificates for the purchased Shares directly to such
brokerage firm in order to complete the sale transaction.




     4. Restrictions on Exercise. The Option may not be exercised if the issuance of the
Shares subject to the Option upon such exercise would constitute a violation of any Applicable
Laws. In addition, the Option may not be exercised until such time as the Plan has been approved
by the stockholders of the Company. If the exercise of the Option within the applicable time
periods set forth in Section 5, 6 and 7 of this Option Agreement is prevented by the provisions of
this Section 4, the Option shall remain exercisable until one (1) month after the date the Grantee
is notified by the Company that the Option is exercisable, but in any event no later than the
Expiration Date set forth in the Notice.



     5. Termination or Change of Continuous Service. In the event the Grantee’s Continuous
Service terminates, other than for Cause, the Grantee may, but only during the Post-



2









 







Termination Exercise Period, exercise the portion of the Option that was vested at the date of
such termination (the “Termination Date”). The Post-Termination Exercise Period shall commence on
the Termination Date. In the event of termination of the Grantee’s Continuous Service for Cause,
the Grantee’s right to exercise the Option shall, except as otherwise determined by the
Administrator, terminate concurrently with the termination of the Grantee’s Continuous Service
(also the “Termination Date”). In no event, however, shall the Option be exercised later than the
Expiration Date set forth in the Notice. In the event of the Grantee’s change in status from
Employee, Director or Consultant to any other status of Employee, Director or Consultant, the
Option shall remain in effect and the Option shall continue to vest in accordance with the Vesting
Schedule set forth in the Notice; provided, however, that with respect to any Incentive Stock
Option that shall remain in effect after a change in status from Employee to Director or
Consultant, such Incentive Stock Option shall cease to be treated as an Incentive Stock Option and
shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day
following such change in status. Except as provided in Sections 6 and 7 below, to the extent that
the Option was unvested on the Termination Date, or if the Grantee does not exercise the vested
portion of the Option within the Post-Termination Exercise Period, the Option shall terminate.



     6. Disability of Grantee. In the event the Grantee’s Continuous Service terminates as
a result of his or her Disability, the Grantee may, but only within twelve (12) months commencing
on the Termination Date (but in no event later than the Expiration Date), exercise the portion of
the Option that was vested on the Termination Date; provided, however, that if such Disability is
not a “disability” as such term is defined in Section 22(e)(3) of the Code and the Option is an
Incentive Stock Option, such Incentive Stock Option shall cease to be treated as an Incentive Stock
Option and shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1)
day following the Termination Date. To the extent that the Option was unvested on the Termination
Date, or if the Grantee does not exercise the vested portion of the Option within the time
specified herein, the Option shall terminate. Section 22(e)(3) of the Code provides that an
individual is permanently and totally disabled if he or she is unable to engage in any substantial
gainful activity by reason of any medically determinable physical or mental impairment which can be
expected to result in death or which has lasted or can be expected to last for a continuous period
of not less than twelve (12) months.



     7. Death of Grantee. In the event of the termination of the Grantee’s Continuous
Service as a result of his or her death, or in the event of the Grantee’s death during the
Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s
termination of Continuous Service as a result of his or her Disability, the person who acquired the
right to exercise the Option pursuant to Section 8 may exercise the portion of the Option that was
vested at the date of termination within twelve (12) months commencing on the date of death (but in
no event later than the Expiration Date). To the extent that the Option was unvested on the date
of death, or if the vested portion of the Option is not exercised within the time specified herein,
the Option shall terminate.



     8. Transferability of Option. The Option, if an Incentive Stock Option, may not be
transferred in any manner other than by will or by the laws of descent and distribution and may be
exercised during the lifetime of the Grantee only by the Grantee. The Option, if a Non-Qualified
Stock Option, may not be transferred in any manner other than by will or by the laws



3









 







of descent and distribution, provided, however, that a Non-Qualified Stock Option may be
transferred during the lifetime of the Grantee to the extent and in the manner authorized by the
Administrator. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries
of the Grantee’s Incentive Stock Option or Non-Qualified Stock Option in the event of the Grantee’s
death on a beneficiary designation form provided by the Administrator. Following the death of the
Grantee, the Option, to the extent provided in Section 7, may be exercised (a) by the person or
persons designated under the deceased Grantee’s beneficiary designation or (b) in the absence of an
effectively designated beneficiary, by the Grantee’s legal representative or by any person
empowered to do so under the deceased Grantee’s will or under the then applicable laws of descent
and distribution. The terms of the Option shall be binding upon the executors, administrators,
heirs, successors and transferees of the Grantee.



     9. Term of Option. The Option must be exercised no later than the Expiration Date set
forth in the Notice or such earlier date as otherwise provided herein. After the Expiration Date
or such earlier date, the Option shall be of no further force or effect and may not be exercised.



     10. Tax Consequences. The Grantee may incur tax liability as a result of the
Grantee’s purchase or disposition of the Shares. THE GRANTEE SHOULD CONSULT A TAX ADVISER BEFORE
EXERCISING THE OPTION OR DISPOSING OF THE SHARES.



     11. Entire Agreement: Governing Law. The Notice, the Plan and this Option Agreement
constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company and the Grantee
with respect to the subject matter hereof, and may not be modified adversely to the Grantee’s
interest except by means of a writing signed by the Company and the Grantee. Nothing in the
Notice, the Plan and this Option Agreement (except as expressly provided therein) is intended to
confer any rights or remedies on any persons other than the parties. The Notice, the Plan and this
Option Agreement are to be construed in accordance with and governed by the internal laws of the
State of Delaware without giving effect to any choice of law rule that would cause the application
of the laws of any jurisdiction other than the internal laws of the State of Delaware to the rights
and duties of the parties. Should any provision of the Notice, the Plan or this Option Agreement
be determined to be illegal or unenforceable, such provision shall be enforced to the fullest
extent allowed by law and the other provisions shall nevertheless remain effective and shall remain
enforceable.



     12. Construction. The captions used in the Notice and this Option Agreement are
inserted for convenience and shall not be deemed a part of the Option for construction or
interpretation. Except when otherwise indicated by the context, the singular shall include the
plural and the plural shall include the singular. Use of the term “or” is not intended to be
exclusive, unless the context clearly requires otherwise.



     13. Administration and Interpretation. Any question or dispute regarding the
administration or interpretation of the Notice, the Plan or this Option Agreement shall be
submitted by the Grantee or by the Company to the Administrator. The resolution of such question
or dispute by the Administrator shall be final and binding on all persons.



4









 





     14. Venue and Waiver of Jury Trial. The Company, the Grantee, and the Grantee’s
assignees pursuant to Section 8 (the “parties”) agree that any suit, action, or proceeding arising
out of or relating to the Notice, the Plan or this Option Agreement shall be brought in the United
States Federal Court serving Howard County, Maryland (or should such court lack jurisdiction to
hear such action, suit or proceeding, in a Maryland state court in Howard County, Maryland) and
that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to
the fullest extent permitted by law, any objection the party may have to the laying of venue for
any such suit, action or proceeding brought in such court. If any one or more provisions of this
Section 14 shall for any reason be held invalid or unenforceable, it is the specific intent of the
parties that such provisions shall be modified to the minimum extent necessary to make it or its
application valid and enforceable.



     15. Notices. Any notice required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon personal delivery, upon deposit for delivery by an
internationally recognized express mail courier service or upon deposit in the United States mail
by certified mail (if the parties are within the United States), with postage and fees prepaid,
addressed to the other party at its address as shown in these instruments, or to such other address
as such party may designate in writing from time to time to the other party.

     1. Exercise of Option. Effective as of the Exercise Date, the undersigned (the
“Grantee”) hereby elects to exercise the Grantee’s option to purchase the Shares of Sourcefire,
Inc. (the “Company”) under and pursuant to the Company’s 2007 Stock Incentive Plan, as amended from
time to time (the “Plan”) and the Stock Option Award Agreement (the “Option Agreement”) and Notice
of Stock Option Award (the “Notice”) described above. Unless otherwise defined herein, the terms
defined in the Plan shall have the same defined meanings in this Exercise Notice.



     2. Representations of the Grantee. The Grantee acknowledges that the Grantee has
received, read and understood the Notice, the Plan and the Option Agreement and agrees to abide by
and be bound by their terms and conditions.



     3. Rights as Stockholder. Until the stock certificate evidencing such Shares is
issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), no right to vote or receive dividends or any other rights as a



1









 







stockholder shall exist with respect to the Shares, notwithstanding the exercise of the
Option. The Company shall issue (or cause to be issued) such stock certificate promptly after the
Option is exercised. No adjustment will be made for a dividend or other right for which the record
date is prior to the date the stock certificate is issued, except as provided in Section 10 of the
Plan.



     4. Delivery of Payment. The Grantee herewith delivers to the Company the full
Exercise Price for the Shares, which, to the extent selected, shall be deemed to be satisfied by
use of the broker-dealer sale and remittance procedure to pay the Exercise Price provided in
Section 3(d) of the Option Agreement.



     5. Tax Consultation. The Grantee understands that the Grantee may suffer adverse tax
consequences as a result of the Grantee’s purchase or disposition of the Shares. The Grantee
represents that the Grantee has consulted with any tax consultants the Grantee deems advisable in
connection with the purchase or disposition of the Shares and that the Grantee is not relying on
the Company for any tax advice.



     6. Taxes. The Grantee agrees to satisfy all applicable foreign, federal, state and
local income and employment tax withholding obligations and herewith delivers to the Company the
full amount of such obligations or has made arrangements acceptable to the Company to satisfy such
obligations. In the case of an Incentive Stock Option, the Grantee also agrees, as partial
consideration for the designation of the Option as an Incentive Stock Option, to notify the Company
in writing within thirty (30) days of any disposition of any shares acquired by exercise of the
Option if such disposition occurs within two (2) years from the Date of Award or within one (1)
year from the date the Shares were transferred to the Grantee.



     7. Successors and Assigns. The Company may assign any of its rights under this
Exercise Notice to single or multiple assignees, and this agreement shall inure to the benefit of
the successors and assigns of the Company. This Exercise Notice shall be binding upon the Grantee
and his or her heirs, executors, administrators, successors and assigns.



     8. Construction. The captions used in this Exercise Notice are inserted for
convenience and shall not be deemed a part of this agreement for construction or interpretation.
Except when otherwise indicated by the context, the singular shall include the plural and the
plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless
the context clearly requires otherwise.



     9. Administration and Interpretation. The Grantee hereby agrees that any question or
dispute regarding the administration or interpretation of this Exercise Notice shall be submitted
by the Grantee or by the Company to the Administrator. The resolution of such question or dispute
by the Administrator shall be final and binding on all persons.



     10. Governing Law; Severability. This Exercise Notice is to be construed in
accordance with and governed by the internal laws of the State of Delaware without giving effect to
any choice of law rule that would cause the application of the laws of any jurisdiction other than
the internal laws of the State of Delaware to the rights and duties of the parties. Should any
provision of this Exercise Notice be determined by a court of law to be illegal or unenforceable,



2









 







such provision shall be enforced to the fullest extent allowed by law and the other provisions
shall nevertheless remain effective and shall remain enforceable.



     11. Notices. Any notice required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon personal delivery, upon deposit for delivery by an
internationally recognized express mail courier service or upon deposit in the United States mail
by certified mail (if the parties are within the United States), with postage and fees prepaid,
addressed to the other party at its address as shown below beneath its signature, or to such other
address as such party may designate in writing from time to time to the other party.



     12. Further Instruments. The parties agree to execute such further instruments and to
take such further action as may be reasonably necessary to carry out the purposes and intent of
this agreement.



     13. Entire Agreement. The Notice, the Plan and the Option Agreement are incorporated
herein by reference and together with this Exercise Notice constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and the Grantee with respect to the subject matter
hereof, and may not be modified adversely to the Grantee’s interest except by means of a writing
signed by the Company and the Grantee. Nothing in the Notice, the Plan, the Option Agreement and
this Exercise Notice (except as expressly provided therein) is intended to confer any rights or
remedies on any persons other than the parties.
