reduced, offset or subject to recovery by the Company or any of its subsidiaries or affiliates by reason of any compensation earned by Executive as the result of employment by another employer after Executive’s employment with the Company
terminates for any reason. In addition, Executive shall be under no obligation to seek other employment or to take any other actions to mitigate the amounts payable under Section 8. 

8.6 Sections 280G and 4999. 
 (a) In the event of a Change in Control, or other 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 a certified public accounting firm designated by the Company (the “Accounting Firm”) 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 Executive under this Agreement, and any other agreement or plan benefiting the Executive (collectively the “Original
Payments”), to determine the applicability of Section 4999 of the Code to the Executive in connection with such event. If the Accounting Firm determines that the Original Payments are subject to excise taxes under Section 4999 of the
Code (the “Excise Tax”), then: 
 (i) If (A) the aggregate Original Payments exceed an amount (the
“Parachute Threshold”) equal to two hundred ninety nine percent (299%) of the Executive’s “base amount,” as defined in Section 280G(b)(3) of the Code, and (B) such excess is equal to four and six-tenths
percent (4.6%) of the Parachute Threshold or less, the Original Payments shall be reduced (but not below zero) to the extent necessary so that no portion of the Original Payments is subject to the Excise Tax (with such reduction effected in
accordance with Section 8.6(f) below); or 
 (ii) If (A) the aggregate Original Payments exceed the Parachute
Threshold, and (B) such excess is equal to more than four and six-tenths percent (4.6%) of the Parachute Threshold, then an additional amount shall be paid to the Executive (the “Gross-Up Amount”) such that the net proceeds of
the Gross-Up Amount to the Executive, after deduction of the Excise Tax (including interest and penalties) and any federal, state and local income taxes and employment taxes (including interest and penalties) upon the Gross-Up Amount, shall be equal
to the Excise Tax on the Original Payments. 

 (b) The Accounting Firm will perform the calculations in conformity with the foregoing
provisions and will provide the Executive with a copy of their calculations. The intent of the parties is that, except as set forth in Section 8.6(a)(i), the Company shall be solely responsible for, and shall pay, any Excise Tax on the Original
Payments and Gross-Up Amount and any income and employment taxes (including, without limitation, penalties and interest) imposed on any Gross-Up Amount payable hereunder. 
 (c) If no determination by the Accounting Firm is made prior to the time the Executive is required to file a tax return reflecting Excise Taxes on any portion of the Original Payments, the Executive will
be entitled to receive a Gross-Up Amount calculated on the basis of the Excise Tax that the Executive reports in such tax return, within thirty (30) days after the filing of such tax return. The Executive agrees that, for the purposes of the
foregoing sentence, the Executive is not required to file a tax return until the Executive has obtained the maximum number and length of filing extensions available, and Executive shall have provided a copy of the relevant portions of such tax
return to the Company not less than ten (10) days prior to filing such tax return. If, subsequent to the Executive’s filing of such tax return but within one hundred eighty (180) days thereafter, the Accounting Firm determines that
the aggregate Original Payments should be reduced pursuant to Section 8.6(a)(i), the Executive shall reimburse the Company the amount of such reduction, promptly file an amended tax return reflecting such reduction, and promptly take any steps
reasonably required to obtain a refund of any Excise Tax paid with respect to the Original Payments. 
 (d) If any tax authority
finally determines that a greater Excise Tax should be imposed upon the Original Payments or the Gross-Up Amount than is determined by the Accounting Firm or reflected in the Executive’s tax returns, the Executive shall be entitled to receive
an additional Gross-Up Amount calculated on the basis of the additional amount of Excise Tax determined to be payable by such tax authority (including related penalties and interest) from the Company within thirty (30) days after such
determination. The Executive shall cooperate with the Company as it may reasonably request to permit the Company (at its sole expense) to contest the determination of such taxing authority in order to minimize the amount payable under this
Section 8.6. 
 (e) If any tax authority finally determines the Excise Tax payable by the Executive to be less than the
amount taken into account hereunder in calculating the Gross-Up Amount, the Executive shall repay to the Company, within thirty (30) days after the Executive’s receipt of a tax refund resulting from that determination, to the extent of
such refund, the portion of the Gross-Up Amount attributable to such reduction (including the refunded portion of Gross-Up Amount attributable to the Excise Tax and federal, state and local income and employment taxes imposed on the Gross-Up Amount
being repaid, less any additional income tax resulting from receipt of such refund). 
 (f) If the Original Payments are to be
reduced pursuant to Section 8.6(a)(i) above, then the amounts payable under this Agreement will be reduced or eliminated by determining the Parachute Payment Ratio (as defined below) for each Original Payment and then reducing the Original
Payments in order beginning with the Original Payment with the highest Parachute 

 
Payment Ratio. For Original Payments with the same Parachute Payment Ratio, such payments shall be reduced based on the time of payment of such Original Payments, with amounts having later
payment dates being reduced first. For Original Payments with the same Parachute Payment Ratio and the same time of payment, such Original Payments shall be reduced on a pro rata basis (but not below zero) prior to reducing Original Payments with a
lower Parachute Payment Ratio. For purposes hereof, the term “Parachute Payment Ratio” shall mean a fraction, the numerator of which is the value of the applicable payment for purposes of Section 280G of the Code, and the denominator
of which is the intrinsic value of such Parachute Payment. 
 (g) Notwithstanding the foregoing, if on the date of the
Executive’s termination, the Executive is a “specified employee” within the meaning of Section 409A of the Code and any Original Payments are made on account of the Executive’s termination of employment, any Gross-Up Amount
that would otherwise be due under this Section 8.6 and that would constitute deferred compensation within the first six (6) months following the Executive’s termination of employment shall instead be subject to the six (6) month
delay to the extent required by Section 11.7 below. The Executive’s receipt of a Gross-Up Amount for Excise Tax due in one taxable year shall not affect the Executive’s eligibility for a Gross-Up Amount for Excise Tax due in another
taxable year. The Executive’s rights under this Section 8.6 are not subject to liquidation or exchange for another benefit. 
 8.7 Board/Committee Resignation. Upon termination of Executive’s employment for any reason, Executive will be deemed to have resigned, as of the date of such termination and to the extent
applicable, from all positions he then holds with the Company or its affiliates, including any position(s) on the Board, voluntarily, without any further required action by Executive, and Executive, at the Board’s request, will execute any
documents necessary to reflect his resignation. 
 9. Proprietary Information, Inventions, and Non-Competition Agreement.
As a condition to his employment with the Company, Executive shall execute and comply with the Company’s Employee Proprietary Information, Inventions, and Non-Competition Agreement, in the form attached hereto as Exhibit D.

 10. Specific Performance. Executive acknowledges and agrees that the Company’s remedies at law for a breach or
threatened breach of any of the provisions of Section 9 or the Employee Proprietary Information, Inventions, and Non-Competition Agreement would be inadequate and the Company would suffer irreparable damages as a result of such breach or
threatened breach. In recognition of this fact, Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company, without posting any bond, shall be entitled to cease making any payments or
providing any benefit otherwise required by this Agreement and obtain equitable relief in the form of specific performance, temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available.

 11. Miscellaneous. 

11.1 Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of
Delaware, without regard to conflicts of laws principles thereof. Any and all disputes between the parties which may arise pursuant to this Agreement shall be heard and determined before an appropriate state or federal court serving Howard County,
Maryland. The parties acknowledge that such courts have jurisdiction to interpret and enforce the provisions of this Agreement, and the parties consent to, and waive any and all objections that they may have as to, personal jurisdiction and/or venue
in such courts. 
 11.2 Expenses. In the event of any dispute between the Company and Executive as to the interpretation,
terms, validity or enforceability of (including any dispute about the amount of any payment pursuant to) this Agreement, the prevailing party shall be entitled to recover from the non-prevailing party any and all of such prevailing party’s
costs and expenses incurred in connection with any such dispute, including reasonable attorneys’ fees. 
 11.3 Entire
Agreement; Amendments. This Agreement, together with the Exhibits hereto, contains the entire understanding of the parties with respect to the employment of Executive by the Company. There are no restrictions, agreements, promises, warranties,
covenants or undertakings between the parties with respect to the subject matter herein other than those expressly set forth herein. This Agreement may not be altered, modified, or amended except by written instrument signed by the parties hereto.

 11.4 No Waiver. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion
shall not be considered a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. 

11.5 Severability. In the event that any one or more of the provisions of this Agreement shall be or become invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Agreement shall not be affected thereby. 
 11.6 Assignment. This Agreement and all of Executive’s rights and duties hereunder, shall not be assignable or delegable by Executive; except to the extent permitted by the Company in writing.
Any purported assignment or delegation by Executive in violation of the foregoing shall be null and void ab initio and of no force and effect. This Agreement may be assigned by the Company to a person or entity which is a successor in
interest to substantially all of the business operations of the Company. Upon such assignment, the rights and obligations of the Company hereunder shall become the rights and obligations of such successor person or entity. 

11.7 Compliance with IRC Section 409A. To the extent applicable, it is intended that this Agreement and any payment made
hereunder shall comply with the requirements of (or an exemption or exclusion from) Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and any related regulations or other guidance promulgated with respect to
such section by the U.S. Department of the Treasury or the Internal Revenue Service (“Section 409A”), and any ambiguities in this Agreement will be interpreted accordingly. Any provision of this Agreement that would cause this Agreement to
fail to satisfy Section 409A will have no force and effect until amended to comply therewith (which amendment may be retroactive to the extent permitted by Section 409A). 

 (a) Notwithstanding anything contained herein to the contrary, to the extent required
in order to avoid accelerated taxation and/or tax penalties under Section 409A, Executive shall not be considered to have terminated employment with the Company for purposes of this Agreement and no payments shall be due to Executive under this
Agreement which are payable upon or following Executive’s termination of employment until Executive would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A. 

(b) Notwithstanding anything in this Agreement to the contrary, if at the time of Executive’s termination of employment with
the Company Executive is a “specified employee” as defined in Section 409A and the deferral in accordance with Section 409A(a)(2)(B) of the Code of the commencement of any payments or benefits otherwise payable hereunder as a
result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any
reduction in such payments or benefits ultimately paid or provided to Executive) until the date that is six months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A
without the imposition of any accelerated or additional tax). In addition, for purposes of the Agreement, each amount (including each installment payment that may be paid pursuant to Section 8.2) to be paid or benefit to be provided to
Executive pursuant to this Agreement shall be construed as a separate identified payment for purposes of Section 409A. 

(c) With respect to expenses eligible for reimbursement or in-kind benefits under the terms of the Agreement, (i) the amount
of such expenses eligible for reimbursement or in-kind benefits provided in any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits provided in another taxable year, (ii) any reimbursements or in-kind
benefits shall be made no later than the end of the calendar year following the calendar year in which the related expenses were incurred, (iii) any reimbursement is for expenses incurred during the period of time specified in the Agreement and
(iv) Executive’s right to have the Company pay or provide such reimbursements or in-kind benefits may not be liquidated or exchanged for any other benefit, except, in each case, to the extent that the right to reimbursement or in-kind
benefits does not provide for a “deferral of compensation” within the meaning of Section 409A. 
 (d) Where
required to avoid additional taxes under Section 409A, no transaction or event shall constitute a Change in Control for purposes of this Agreement unless such transaction or event also constitutes a “change in the ownership or effective
control, or in the ownership of a substantial portion of the assets,” each as defined in Section 409A. 
 The Company shall consult
with Executive in good faith regarding the implementation of the provisions of this Section 11.7; provided that neither the Company nor any of its employees or representatives shall have any liability to Executive with respect to any taxes,
penalties, interest or other costs or expenses Executive (or his estate or beneficiaries) may incur with respect to or as a result of Section 409A. 

 11.8 Successors; Binding Agreement. This Agreement shall inure to the benefit of and
be binding upon personal or legal representatives, executors, administrators, successors, assigns, agents, affiliates, heirs, distributees, devisees and legatees. The Company shall require any successor to all or substantially all of the assets or
business of the Company to agree to assume the Agreement.

 EXHIBIT A 
 Form of General Release 
 This General Release (“Release”)
is entered into as of             , 20     (the “Execution Date”), by and between John Becker (“Executive”) and Sourcefire, Inc., a Delaware
corporation, and its successors and assigns (the “Company”). Executive and the Company are sometimes collectively referred to as the “Parties”. 
 1. Executive’s employment with the Company is terminated effective as of             , 20     (hereinafter
“Termination Date”). 
 2. In consideration for Executive’s execution of this Release and Executive’s
promises and covenants contained herein and in that certain Employment Agreement, dated             , 2013, between the Company and Executive (the “Employment Agreement”), the
Company agrees to deliver to Executive those payments and benefits set forth in Section 8.     of the Employment Agreement, on the terms and conditions described therein, after Executive executes this Release. 

3. Executive and Executive’s agents and assigns (collectively, the “Releasors”) hereby waive, release and forever
discharge the Company and its predecessors, subsidiaries and affiliates, and their respective officers, directors, stockholders, agents, attorneys, employees, successors or assigns (collectively, the “Releasees”) of and from any and all
actions, causes of action, suits, debts, dues, sums of money, accounts, reckonings, bonds, bills, specialties, covenants, contracts, controversies, agreements, promises, variances, trespasses, damages, judgments, extents, executions, claims and
demands whatsoever (including attorneys’ fees, costs and disbursements actually incurred), in law or equity, whether known or unknown, suspected or unsuspected, of every kind and nature whatsoever, which may now exist or which may later arise,
including without limitation under Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; Sections 1981 through 1988 of Title 42 of the United States Code, as amended; the Fair Labor Standards Act, as amended; the Age
Discrimination in Employment Act of 1967, as amended; the Americans With Disabilities Act; the Employee Retirement Income Security Act of 1974, as amended; the Immigration Reform and Control Act, as amended; the Workers Adjustment and Retraining
Notification Act, as amended; the Occupational Safety and Health Act, as amended; Article 49B of the Maryland Code; the California Fair Employment and Housing Act, as amended; the California Family Rights Act, as amended; and all other federal,
state and local laws, statutes, rules or regulations of any type or description, including contract law, tort law, civil rights laws, public policy or common law, which the Releasors ever had, now have or hereafter can, shall or may have against the
Releasees or any of them for, upon or by reason of any matter, cause or thing whatsoever from the beginning of the world to the day of the date of this Agreement, except as otherwise provided in this Agreement. 

4. Executive acknowledges that there may exist claims or facts in addition to or different from those which are now known or believed by
the Parties to exist and Executive agrees that it is Executive’s intention to fully settle and release such claims, whether known or unknown, that may exist as of the date of this agreement. Executive therefore waives his rights under
Section 1542 of the Civil Code of California, which states: 
 A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN TO HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR. 

 Executive acknowledges he has read this Release, including the waiver of California Civil
Code Section 1542. Executive further acknowledges he has been specifically advised to consult an attorney about the Release and specifically about the waiver of Section 1542, and that he understands the Release and the Section 1542
waiver, and so freely and knowingly enters into this Release. Executive understands he may later discover facts different from or in addition to those known or now believed to be true with respect to the matters released or described in this
Release. Executive agrees that the release and agreements contained in this Release shall be and will remain effective in all respects notwithstanding any later discovery of any such different or additional facts. Executive hereby assumes any and
all risk of any mistake in connection with the true facts involved in the matters, disputes, or controversies described in this Release or with regard to any facts which are now unknown to him. 

5. Notwithstanding anything to the contrary set forth in paragraph 3, the Releasors do not waive, release or discharge the Releasees from
(i) any claims regarding any payments or benefits due to Executive in connection with his execution of this Release pursuant to paragraph 2, (ii) Executive’s rights to indemnification from the Company whether pursuant to a prior
agreement, the Company’s bylaws, applicable law or otherwise, (iii) any claim which the Releasors may have as the beneficial owner of securities of the Company, or (iv) any claim which may arise in the future from events or actions
occurring after the date that Executive executes this Release. 
 6. Executive hereby represents that Executive has not filed or
commenced any proceeding against any of the Releasees regarding the claims and matters discussed in paragraph 3, and hereby covenants and agrees not to file or commence any proceeding against any of the Releasees with respect to, or in any way
connected with, Executive’s employment with the Company or the termination thereof, or otherwise regarding the claims and matters discussed in paragraph 3, in each case, arising on or prior to the date of execution of this Release. Executive
also agrees that if Executive breaches these representations or covenants, then Executive authorizes the Releasees to, and each shall have the right to, cause any such proceeding to be dismissed on the grounds that Executive has completely released
and waived such proceeding. 
 7. Executive warrants that no promise or inducement has been offered for this Release other than
as set forth herein and that this Release is executed without reliance upon any other promises or representations, oral or written. Any modification of this Release must be made in writing and be signed by Executive and the Company. 

8. If any provision of this Release or compliance by Executive or the Company with any provision of the Release constitutes a violation
of any law, or is or becomes unenforceable or void, then such provision, to the extent only that it is in violation of law, unenforceable or void, 

 
will be deemed modified to the extent necessary so that it is no longer in violation of law, unenforceable or void, and such provision will be enforced to the fullest extent permitted by law. If
such modification is not possible, such provision, to the extent that it is in violation of law, unenforceable or void, will be deemed severable from the remaining provisions of this Release, which provisions will remain binding on both Executive
and the Company. This Release is governed by, and construed and interpreted in accordance with the laws of the State of Delaware, without regard to principles of conflicts of law. Executive consents to venue and personal jurisdiction in the
appropriate state of federal court serving Howard County, Maryland for disputes arising under this Release. This Release represents the entire understanding with the Parties with respect to subject matter herein; no oral representations have been
made or relied upon by the Parties. 
 9. Executive specifically agrees and acknowledges that: (i) he has read and
understands the terms of this Release; (ii) he has hereby been advised by the Company to consult with an attorney prior to executing this Release; (iii) the Company has given him a period of up to twenty-one (21) days within which to
consider this Release, which period shall be waived by Executive’s voluntary execution prior to the expiration of the twenty–one day period; and (iv) following his execution of this Release he has seven (7) days in which to
revoke his release as set forth in this paragraph 9 only and that, if he chooses not to so revoke, the Release shall then become effective and enforceable and the payment listed above shall then be made to Executive in accordance with the terms
of this Release. To cancel this Release, Executive understands that he must give a written revocation to the General Counsel of the Company at 9770 Patuxent Woods Drive, Columbia, Maryland 21046, either by hand delivery or certified mail within the
seven–day period. If he rescinds the Release, it will not become effective or enforceable and he will not be entitled to any benefits from the Company. 
 10. No action taken by the Parties hereto, or either of them, either previously or in connection with this Agreement, shall be deemed or constructed to be: (i) an admission of the truth or falsity of
any claims heretofore made; or (ii) an acknowledgment or admission by either party of any fault or liability whatsoever to the other party or to any third party. 
 11. Each of the Released Parties, other than the Company, is intended third party beneficiaries of this Release.

 EXHIBIT B3 
 Form of Stock Option Agreement 
 SOURCEFIRE, INC. 

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. Notwithstanding the foregoing, if in connection with a Corporate Transaction or Change in Control, any of Grantee’s Options granted hereunder are not Assumed, then
such Options shall become fully and immediately vested and Grantee shall be eligible to exercise the Options effective immediately prior to the Corporate Transaction or Change in Control, in accordance with the terms and subject to the conditions
set forth in the Notice, the Plan and this Agreement. 
 (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 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(c), 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-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 5 and 6 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 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.

 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

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 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

 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.

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

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

 SOURCEFIRE, INC. 
 2007 STOCK INCENTIVE PLAN 
 NOTICE OF RESTRICTED STOCK UNIT AWARD 

Grantee’s Name and Address: 
 JOHN C.
BECKER 
 [ADDRESS] 
 UNITED STATES

 You (the “Grantee”) have been granted an award of Restricted Stock Units (the “Award”), subject to the terms and
conditions of this Notice of Restricted Stock Unit Award (the “Notice”), the Sourcefire, Inc. 2007 Stock Incentive Plan, as amended from time to time (the “Plan”) and the Restricted Stock Unit Agreement (the
“Agreement”) attached hereto, as follows. Unless otherwise provided herein, the terms in this Notice shall have the same meaning as those defined in the Plan. 

 

			
	Award Number	  	[TBD]
	Date of Award	  	May 6, 2013
	Vesting Commencement Date	  	May 6, 2013
	Total Number of Restricted Stock	  	
	Units Awarded (the “Units”)	  	70,000

 Vesting Schedule: 
 Subject to the Grantee’s Continuous Service and other limitations set forth in this Notice, the Agreement and the Plan, the Units will “vest” in accordance with the following schedule (the
“Vesting Schedule”): 
 Grantee’s interest in the Units will vest in full as to one hundred percent (100%) of
any Units that remain unvested as of the fifth (5th) anniversary of the Vesting Commencement Date; provided, however, that on each of the first, second, third and fourth anniversaries of the Vesting Commencement Date, Grantee’s interest
will earlier vest as to twenty-five percent (25%) of the Total Number of Restricted Stock Units Awarded if one hundred percent (100%) of the annual performance goals with respect to the Award, as established by the Compensation Committee
for the fiscal year immediately preceding such anniversary of the Vesting Commencement Date, are met. 
 The determination as to
whether the annual performance goals for each applicable fiscal year have been met shall be made by the Compensation Committee. In the event that the Compensation Committee determines that the annual performance goals for a fiscal year have been met
and such determination is made after the applicable anniversary of the 
 Vesting Commencement Date, the Units subject to vesting
on such anniversary will instead vest on the date that such determination is made. 

 In the event of the Grantee’s change in status from Employee to Consultant or Director, the
determination of whether such change in status results in a termination of Continuous Service will be determined in accordance with Section 409A of the Code. During any authorized leave of absence, the vesting of the Units as provided in this
schedule shall be suspended (to the extent permitted under Section 409A of the Code) after the leave of absence exceeds a period of three (3) months. The Vesting Schedule of the Units shall be extended by the length of the suspension.
Vesting of the Units shall resume upon the Grantee’s termination of the leave of absence and return to service to the Company or a Related Entity; provided, however, that if the leave of absence exceeds six (6) months, and a return to
service upon expiration of such leave is not guaranteed by statute or contract, then (a) the Grantee’s Continuous Service shall be deemed to terminate on the first date following such six-month period and (b) the Grantee will forfeit
the Units that are unvested on the date of the Grantee’s termination of Continuous Service. An authorized leave of absence shall include sick leave, military leave, or other bona fide leave of absence (such as temporary employment by the
government). Notwithstanding the foregoing, with respect to a leave of absence due to any medically determinable physical or mental impairment of the Grantee that can be expected to result in death or can be expected to last for a continuous period
of not less than six (6) months, where such impairment causes the Grantee to be unable to perform the duties of the Grantee’s position of employment or substantially similar position of employment, a twenty-nine (29) month period of
absence shall be substituted for such six (6) month period above. 
 For purposes of this Notice and the Agreement, the term
“vest” shall mean, with respect to any Units, that such Units are no longer subject to forfeiture to the Company. If the Grantee would become vested in a fraction of a Unit, such Unit shall not vest until the Grantee becomes vested in the
entire Unit. 
 Vesting shall cease upon the date the Grantee terminates Continuous Service for any reason, including death or Disability. In
the event the Grantee terminates Continuous Service for any reason, including death or Disability, any unvested Units held by the Grantee immediately upon such termination of the Grantee’s Continuous Service shall be forfeited and deemed
reconveyed to the Company and the Company shall thereafter be the legal and beneficial owner of such reconveyed Units and shall have all rights and interest in or related thereto without further action by the Grantee. 

IN WITNESS WHEREOF, the Company and the Grantee have executed this Notice and agree that the Award is to be governed by the terms and conditions of this
Notice, the Plan, and the Agreement.

AGREEMENT, NOR IN THE PLAN, SHALL CONFER UPON THE GRANTEE ANY RIGHT WITH RESPECT TO CONTINUATION OF THE GRANTEE’S CONTINUOUS SERVICE, NOR SHALL IT INTERFERE IN ANY WAY WITH THE GRANTEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE THE
GRANTEE’S CONTINUOUS SERVICE AT ANY TIME, WITH OR WITHOUT CAUSE, AND WITH OR WITHOUT NOTICE. THE GRANTEE ACKNOWLEDGES THAT UNLESS THE GRANTEE HAS A WRITTEN EMPLOYMENT AGREEMENT WITH THE COMPANY TO THE CONTRARY, THE GRANTEE’S STATUS IS AT
WILL. 
 Grantee Acknowledges and Agrees: 
 The Grantee acknowledges receipt of a copy of the Plan and the Agreement and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts the Award subject to all of the
terms and provisions hereof and thereof. The Grantee has reviewed this Notice, the Agreement and the Plan in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Notice and fully understands all provisions
of this Notice, the Agreement and the Plan. The Grantee further agrees and acknowledges that this Award is a non-elective arrangement pursuant to Section 409A of the Code. 
 The Grantee further acknowledges that, from time to time, the Company may be in a “blackout period” and/or subject to applicable federal securities laws that could subject the Grantee to
liability for engaging in any transaction involving the sale of the Company’s Shares. The Grantee further acknowledges and agrees that, prior to the sale of any Shares acquired under this Award, it is the Grantee’s responsibility to
determine whether or not such sale of Shares will subject the Grantee to liability under insider trading rules or other applicable federal securities laws. 
 The Grantee understands that the Award is subject to the Grantee’s consent to access this Notice, the Agreement and the Plan (collectively, the “Plan Documents”) in electronic form on the
Company’s intranet or the website of the Company’s designated brokerage firm, if applicable. By signing below (or providing an electronic signature by clicking below) and accepting the grant of the Award, the Grantee: (i) consents to

(iv) acknowledges that the Grantee is familiar with and accepts the Award subject to the terms and provisions of the Plan Documents. 
 The
Company may, in its sole discretion, decide to deliver any Plan Documents by electronic means or request the Grantee’s consent to participate in the Plan by electronic means. The Grantee hereby consents to receive such documents by electronic
delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company. 

 The Grantee hereby agrees that all questions of interpretation and administration relating to this Notice,
the Plan and the Agreement shall be resolved by the Administrator in accordance with Section 8 of the Agreement. The Grantee further agrees to the venue and jurisdiction selection in accordance with Section 9 of the Agreement. The Grantee
further agrees to notify the Company upon any change in his or her residence address indicated in this Notice.

 2007 STOCK INCENTIVE PLAN 
 RESTRICTED STOCK UNIT AGREEMENT 
 1. Issuance of Units. Sourcefire, Inc., a Delaware
corporation (the “Company”), hereby issues to the Grantee (the “Grantee”) named in the Notice of Restricted Stock Unit Award (the “Notice”) an award (the “Award”) of the Total Number of Restricted Stock Units
Awarded set forth in the Notice (the “Units”), subject to the Notice, this Restricted Stock Unit Agreement (the “Agreement”) and the terms and provisions of the Sourcefire, Inc. 2007 Stock Incentive Plan, as amended from time to
time (the “Plan”), which is incorporated herein by reference. Unless otherwise provided herein, the terms in this Agreement shall have the same meaning as those defined in the Plan. 
 2. Transfer Restrictions. The Units may not be transferred in any manner other than by will or by the laws of descent and distribution. 
 3. Conversion of Units and Issuance of Shares. 
 (a) General. Subject to Sections
3(b) and 3(c), one share of Common Stock shall be issuable for each Unit subject to the Award (the “Shares”) upon vesting. Immediately thereafter, or as soon as administratively feasible, the Company will transfer the appropriate number of
Shares to the Grantee after satisfaction of any required tax or other withholding obligations. Any fractional Unit remaining after the Award is fully vested shall be discarded and shall not be converted into a fractional Share. Notwithstanding the
foregoing, the relevant number of Shares shall be issued no later than March 15th of the year following the calendar year in which the Award vests. Notwithstanding the foregoing, if in connection with a Corporate Transaction or Change in
Control, any of Grantee’s Awards made hereunder are not Assumed, then Grantee shall be eligible to receive full vesting of the Award effective immediately prior to the Corporate Transaction or Change in Control, in accordance with the terms and
subject to the conditions set forth in the Notice, the Plan and this Agreement. Any such Award shall be settled within thirty (30) days following the date of the Corporate Transaction or Change in Control but in no event later than
March 15 of the calendar year following the calendar year in which the Corporate Transaction or Change in Control occurs. 
 (b) Delay
of Conversion. The conversion of the Units into the Shares under Section 3(a) above, shall be delayed in the event the Company reasonably anticipates that the issuance of the Shares would constitute a violation of federal securities laws or
other Applicable Law. If the conversion of the Units into the Shares is delayed by the provisions of this Section 3(b), the conversion of the Units into the Shares shall occur at the earliest date at which the Company reasonably anticipates
issuing the Shares will not cause a violation of federal securities laws or other Applicable Law. For purposes of this Section 3(b), the issuance of Shares that would cause inclusion in gross income or the application of any penalty provision
or other provision of the Code is not considered a violation of Applicable Law. 

 (c) Delay of Issuance of Shares. The Company shall delay the issuance of any Shares under this
Section 3 to the extent necessary to comply with Section 409A(a)(2)(B)(i) of the Code (relating to payments made to certain “specified employees” of certain publicly-traded companies); in such event, any Shares to which the
Grantee would otherwise be entitled during the six (6) month period following the date of the Grantee’s termination of Continuous Service will be issuable on the first business day following the expiration of such six (6) month
period. 
 4. Right to Shares. The Grantee shall not have any right in, to or with respect to any of the Shares (including any voting
rights or rights with respect to dividends paid on the Common Stock) issuable under the Award until the Award is settled by the issuance of such Shares to the Grantee. 
 5. Taxes. 
 (a) Tax Liability. The Grantee is ultimately liable and responsible for
all taxes owed by the Grantee in connection with the Award, regardless of any action the Company or any Related Entity takes with respect to any tax withholding obligations that arise in connection with the Award. Neither the Company nor any Related
Entity makes any representation or undertaking regarding the treatment of any tax withholding in connection with any aspect of the Award, including the grant, vesting, assignment, release or cancellation of the Units, the delivery of Shares, the
subsequent sale of any Shares acquired upon vesting and the receipt of any dividends or dividend equivalents. The Company does not commit and is under no obligation to structure the Award to reduce or eliminate the Grantee’s tax liability.

 (b) Payment of Withholding Taxes. Prior to any event in connection with the Award (e.g., vesting) that the Company determines may
result in any tax withholding obligation, whether United States federal, state, local or non-U.S., including any social insurance, employment tax, payment on account or other tax-related obligation (the “Tax Withholding Obligation”), the
Grantee must arrange for the satisfaction of the minimum amount of such Tax Withholding Obligation in a manner acceptable to the Company. 
 (i)
By Share Withholding. If permissible under Applicable Law, the Grantee authorizes the Company to, upon the exercise of its sole discretion, withhold from those Shares otherwise issuable to the Grantee the whole number of Shares sufficient to
satisfy the minimum applicable Tax Withholding Obligation. The Grantee acknowledges that the withheld Shares may not be sufficient to satisfy the Grantee’s minimum Tax Withholding Obligation. Accordingly, the Grantee agrees to pay to the
Company or any Related Entity as soon as practicable, including through additional payroll withholding, any amount of the Tax Withholding Obligation that is not satisfied by the withholding of Shares described above. 

(ii) By Sale of Shares. Unless the Grantee determines to satisfy the Tax Withholding Obligation by some other means in accordance with clause
(iii) below, the Grantee’s acceptance of this Award constitutes the Grantee’s instruction and authorization to the Company and any brokerage firm determined acceptable to the Company for such purpose to, upon the exercise of
Company’s sole discretion, sell on the Grantee’s behalf a whole number of Shares from those 

 
Shares issuable to the Grantee as the Company determines to be appropriate to generate cash proceeds sufficient to satisfy the minimum applicable Tax Withholding Obligation. Such Shares will be
sold on the day following the date on which such Tax Withholding Obligation arises (e.g., a vesting date) or as soon thereafter as practicable. The Grantee will be responsible for all broker’s fees and other costs of sale, and the Grantee
agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale. To the extent the proceeds of such sale exceed the Grantee’s minimum Tax Withholding Obligation, the Company agrees to pay
such excess in cash to the Grantee. The Grantee acknowledges that the Company or its designee is under no obligation to arrange for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy the
Grantee’s minimum Tax Withholding Obligation. Accordingly, the Grantee agrees to pay to the Company or any Related Entity as soon as practicable, including through additional payroll withholding, any amount of the Tax Withholding Obligation
that is not satisfied by the sale of Shares described above. 
 (iii) By Check, Wire Transfer or Other Means. At any time not less than
five (5) business days (or such fewer number of business days as determined by the Administrator) before any Tax Withholding Obligation arises (e.g., a vesting date), the Grantee may elect to satisfy the Grantee’s Tax Withholding
Obligation by delivering to the Company an amount that the Company determines is sufficient to satisfy the Tax Withholding Obligation by (x) wire transfer to such account as the Company may direct, (y) delivery of a certified check payable
to the Company, or (z) such other means as specified from time to time by the Administrator. 
 Notwithstanding the foregoing, the Company
or a Related Entity also may satisfy any Tax Withholding Obligation by offsetting any amounts (including, but not limited to, salary, bonus and severance payments) payable to the Grantee by the Company and/or a Related Entity. Furthermore, in the
event of any determination that the Company has failed to withhold a sum sufficient to pay all withholding taxes due in connection with the Award, the Grantee agrees to pay the Company the amount of such deficiency in cash within five (5) days
after receiving a written demand from the Company to do so, whether or not the Grantee is an employee of the Company at that time. 
 6.
Entire Agreement; Governing Law. The Notice, the Plan and this 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. These agreements are to be construed in
accordance with and governed by the internal laws of the State of Maryland 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 Maryland to the
rights and duties of the parties. Should any provision of the Notice or this Agreement be determined to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable. 

7. Construction. The captions used in the Notice and this Agreement are inserted for convenience and shall not be deemed a part of the Award 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. 

 8. Administration and Interpretation. Any question or dispute regarding the administration or
interpretation of the Notice, the Plan or this 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. 

9. Venue and Jurisdiction. The parties agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this
Agreement shall be brought exclusively in the United States District Court for the District of Maryland (or should such court lack jurisdiction to hear such action, suit or proceeding, in a Maryland state court in the County of Howard) 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 9 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. 
 10. 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. 

11. Nature of Award. In accepting the Award, the Grantee acknowledges and agrees that: 
 (a) the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the
Plan and this Agreement; 
 (b) the Award is voluntary and occasional and does not create any contractual or other right to receive future
awards of Units, or benefits in lieu of Units, even if Units have been awarded repeatedly in the past; 
 (c) all decisions with respect to
future awards, if any, will be at the sole discretion of the Company; 
 (d) the Grantee’s participation in the Plan is voluntary;

 (e) the Grantee’s participation in the Plan shall not create a right to any employment with the Grantee’s employer and shall not
interfere with the ability of the Company or the employer to terminate the Grantee’s employment relationship, if any, at any time; 
 (f)
the Award is not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, 

 
end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any
way to, past services for the Company or any Related Entity; 
 (g) in the event that the Grantee is not an Employee of the Company or any
Related Entity, the Award and the Grantee’s participation in the Plan will not be interpreted to form an employment or service contract or relationship with the Company or any Related Entity; 

(h) the future value of the underlying Shares is unknown and cannot be predicted with certainty; 

(i) in consideration of the Award, no claim or entitlement to compensation or damages shall arise from termination of the Award or diminution in value of
the Award or Shares acquired upon vesting of the Award, resulting from termination of the Grantee’s Continuous Service by the Company or any Related Entity (for any reason whatsoever and whether or not in breach of local labor laws) and in
consideration of the grant of the Award, the Grantee irrevocably releases the Company and any Related Entity from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have
arisen, then, by signing the Notice, the Grantee shall be deemed irrevocably to have waived his or her right to pursue or seek remedy for any such claim or entitlement; 
 (j) in the event of termination of the Grantee’s Continuous Service (whether or not in breach of local labor laws), the Grantee’s right to receive Awards under the Plan and to vest in such
Awards, if any, will terminate effective as of the date that the Grantee is no longer providing services and will not be extended by any notice period mandated under local law (e.g., providing services would not include a period of “garden
leave” or similar period pursuant to local law); furthermore, in the event of termination of the Grantee’s Continuous Service (whether or not in breach of local labor laws), the Administrator shall have the exclusive discretion to
determine when the Grantee is no longer providing services for purposes of this Award; 
 (k) the Company is not providing any tax, legal or
financial advice, nor is the Company making any recommendations regarding the Grantee’s participation in the Plan or the Grantee’s acquisition or sale of the underlying Shares; and 
 (l) the Grantee is hereby advised to consult with the Grantee’s own personal tax, legal and financial advisers regarding the Grantee’s participation in the Plan before taking any action related
to the Plan. 
 12. Data Privacy. 
 (a) The Grantee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of the Grantee’s personal data as described in the Notice and this
Agreement by and among, as applicable, the Grantee’s employer, the Company and any Related Entity for the exclusive purpose of implementing, administering and managing the Grantee’s participation in the Plan. 

 (b) The Grantee understands that the Company and the Grantee’s employer may hold certain personal
information about the Grantee, including, but not limited to, the Grantee’s name, home address and telephone number, date of birth, social insurance or other identification number, salary, nationality, job title, any Shares or directorships
held in the Company, details of all Units or any other entitlement to Shares awarded, canceled, vested, unvested or outstanding in the Grantee’s favor, for the exclusive purpose of implementing, administering and managing the Plan
(“Data”). 
 (c) The Grantee understands that Data will be transferred to any third party assisting the Company with the
implementation, administration and management of the Plan. The Grantee understands that the recipients of the Data may be located in the Grantee’s country, or elsewhere, and that the recipients’ country may have different data privacy laws
and protections than the Grantee’s country. The Grantee understands that the Grantee may request a list with the names and addresses of any potential recipients of the Data by contacting the Grantee’s local human resources representative.
The Grantee authorizes the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in
electronic or other form, for the sole purpose of implementing, administering and managing the Grantee’s participation in the Plan. The Grantee understands that Data will be held only as long as is necessary to implement, administer and manage
the Grantee’s participation in the Plan. The Grantee understands that the Grantee may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or
withdraw the consents herein, in any case without cost, by contacting in writing the Grantee’s local human resources representative. The Grantee understands, however, that refusal or withdrawal of consent may affect the Grantee’s ability
to participate in the Plan. For more information on the consequences of the Grantee’s refusal to consent or withdrawal of consent, the Grantee understands that the Grantee may contact the Grantee’s local human resources representative.

 13. Language. If the Grantee has received this Agreement or any other document related to the Plan translated into a language other
than English and if the translated version is different than the English version, the English version will control, unless otherwise prescribed by Applicable Law. 
 14. Amendment and Delay to Meet the Requirements of Section 409A. The Grantee acknowledges that the Company, in the exercise of its sole discretion and without the consent of the Grantee, may
amend or modify this Agreement in any manner and delay the issuance of any Shares issuable pursuant to this Agreement to the minimum extent necessary to meet the requirements of Section 409A of the Code as amplified by any Treasury regulations
or guidance from the Internal Revenue Service as the Company deems appropriate or advisable. In addition, the Company makes no representation that the Award will comply with Section 409A of the Code and makes no undertaking to prevent
Section 409A of the Code from applying to the Award or to mitigate its effects on any deferrals or payments made in respect of the Units. The Grantee is encouraged to consult a tax adviser regarding the potential impact of Section 409A of
the Code.

Company any rights I may have or acquire in such Proprietary Information and recognize that all Proprietary Information shall be the sole property of the Company and its assigns. I have been informed and acknowledge that the unauthorized taking of

 1.3 Third Party Information. I understand, in addition, that the Company has received and in the future will receive from
third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes.
During the term of my employment and thereafter, I will hold Third Party Information in the strictest confidence and will not disclose to anyone (other than Company personnel who need to know such information in connection with their work for the
Company) or use, except in connection with my work for the Company, Third Party Information unless expressly authorized by an officer of the Company in writing. 
 1.4 No Improper Use of Information of Prior Employers and Others. During my employment by the Company I will not improperly use or disclose any confidential information or trade secrets, if any, of
any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto the premises of the Company any unpublished documents or any property belonging to any former employer or any other person to whom I
have an obligation of confidentiality unless consented to in writing by that former employer or person. I will use in the performance of my duties only information which is generally known and used by persons with training and experience comparable
to my own, which is common knowledge in the industry or otherwise legally in the public domain, or which is otherwise provided or developed by the Company.

 

 
 2. ASSIGNMENT OF INVENTIONS. 

2.1 Proprietary Rights. The term “Proprietary Rights” shall mean all trade secret, patent, copyright, mask work and other
intellectual property rights or “moral rights” throughout the world. “Moral rights” refers to any rights to claim authorship of an Invention or to object to or prevent the modification of any Invention, or to withdraw from
circulation or control the publication or distribution of any Invention, and any similar right, existing under judicial or statutory law of any country in the world, or under any treaty, regardless of whether or not such right is denominated or
generally referred to as a “moral right.” 
 2.2 Prior Inventions. Inventions, if any, patented or unpatented, which I
made prior to the commencement of my employment with the Company are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit 1 (Previous Inventions) attached hereto a complete list of
all Inventions that I have, alone or jointly with others, conceived, developed or reduced to practice or caused to be conceived, developed or reduced to practice prior to the commencement of my employment with the Company, that I consider to be my
property or the property of third parties and that I wish to have excluded from the scope of this Agreement (collectively referred to as “Prior Inventions”). If disclosure of any such Prior Invention would cause me to violate
any prior confidentiality agreement, I understand that I am not to list such Prior Inventions in Exhibit 1 but am only to disclose a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the fact that
full disclosure as to such inventions has not been made for that reason. A space is provided on Exhibit 1 for such purpose. If no such disclosure is attached, I represent that there are no Prior Inventions. If, in the course of my employment
with the Company, I incorporate a Prior Invention into a Company product, process or machine, the Company is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights to sublicense through
multiple tiers of sublicensees) to make, have made, modify, use and sell such Prior Invention. Notwithstanding the foregoing, I agree that I will not incorporate, or permit to be incorporated, Prior Inventions in any Company Inventions without the
Company’s prior written consent. 
 2.3 Assignment of Inventions. Subject to Sections 2.4, and 2.6, I hereby assign and agree to

 
assign in the future (when any such Inventions or Proprietary Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to the Company all my right, title and
interest in and to any and all Inventions (and all Proprietary Rights with respect thereto) whether or not patentable or registrable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or
jointly with others, during the period of my employment with the Company. Inventions assigned to the Company, or to a third party as directed by the Company pursuant to this Section 2, are hereinafter referred to as “Company
Inventions.” 
 2.4 Unassigned Inventions. I recognize that this Agreement will not be deemed to require assignment of any
invention that was developed entirely on my own time without using the Company’s equipment, supplies, facilities, or trade secrets and neither related to the Company’s actual or anticipated business, research or development, nor resulted
from work performed by me for the Company. 
 2.5 Obligation to Keep Company Informed. During the period of my employment and for six
(6) months after termination of my employment with the Company, I will promptly disclose to the Company fully and in writing all Inventions authored, conceived or reduced to practice by me, either alone or jointly with others. In addition, I
will promptly disclose to the Company all patent applications filed by me or on my behalf within a year after termination of employment. The Company will keep in confidence and will not use for any purpose or disclose to third parties without my
consent any confidential information disclosed in writing to the Company pursuant to this Agreement. 
 2.6 Government or Third Party. I
also agree to assign all my right, title and interest in and to any particular Company Invention to a third party, including without limitation the United States, as directed by the Company. 
 2.7 Works for Hire. I acknowledge that all original works of authorship which are made by me (solely or jointly with others) within the scope of my employment and which are protectable by copyright
are “works made for hire,” pursuant to United States Copyright Act (17 U.S.C., Section 101). 
 2.8 Enforcement of
Proprietary Rights. I will assist the Company in every proper way to obtain, and from time to time enforce, United States and foreign Proprietary Rights relating to Company

 

 
Inventions in any and all countries. To that end I will execute, verify and deliver such documents and perform such other acts (including appearances as a witness) as the Company may reasonably
request for use in applying for, obtaining, perfecting, evidencing, sustaining and enforcing such Proprietary Rights and the assignment thereof. In addition, I will execute, verify and deliver assignments of such Proprietary Rights to the Company or
its designee. My obligation to assist the Company with respect to Proprietary Rights relating to such Company Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a
reasonable rate after my termination for the time actually spent by me at the Company’s request on such assistance. In the event the Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in
connection with the actions specified in the preceding paragraph, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, which appointment is coupled with an interest, to
act for and in my behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of the preceding paragraph with the same legal force and effect as if executed by me. I hereby waive and
quitclaim to the Company any and all claims, of any nature whatsoever, which I now or may hereafter have for infringement of any Proprietary Rights assigned hereunder to the Company. 
 3. RECORDS. I agree to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that may be required by the Company) of all
Proprietary Information developed by me and all Inventions made by me during the period of my employment at the Company, which records shall be available to and remain the sole property of the Company at all times. 

4. DUTY OF LOYALTY DURING EMPLOYMENT. I understand that my employment
with the Company requires my full attention and effort. I agree that during the period of my employment by the Company I will not, without the Company’s express written consent, engage in any employment or business activity other than for the
Company, including but not limited to employment or business activity which is competitive with, or would otherwise conflict with, my employment by the Company.

 5. NO SOLICITATION OF EMPLOYEES,
CONSULTANTS, CONTRACTORS OR CUSTOMERS. I agree that for the period of my employment by the Company and for two (2) years after the date my employment by the Company ends for any
reason, including but not limited to voluntary termination by me or involuntary termination by the Company, I will not, either directly or through others, (i) solicit or attempt to solicit any employee, independent contractor or consultant of
the Company to become an employee, consultant or independent contractor to or for any other person or entity, or (ii) solicit any customers of the Company with whom I had contact or whose identity I learned as a result of my employment with the
Company if I am working with any Competitive Business as that term is defined in Section 6, below. The parties agree that for purposes of this Agreement, a customer is any person or entity to which the Company has provided goods or services at
any time during the period commencing six (6) months prior to my employment with the Company and ending on the date my employment with the Company ends. 
 6. NON-COMPETE PROVISION. I agree that for the period of my employment with the Company, and for the period of one (1) year after the later of
(i) the date my employment ends for any reason, including but not limited to voluntary termination by me or involuntary termination by the Company, or (ii) the date a court of competent jurisdiction enters an order enforcing this
provision, I will not provide services, similar to those I provided to the Company, to any person or entity in competition with the Company within the United States of America. I acknowledge that this non-compete provision is limited to the types of
activities and services I provided in my employment with the Company. The Company currently engages in the network security business providing products and services for network intrusion detection and prevention, next-generation firewalls and
malware protection; however, the parties acknowledge that this will change as the Company develops. Therefore, the parties agree that a person or entity is in competition with the Company if it provides services or goods similar to those provided by
the Company at the time my employment with the Company ends (a “Competitive Business”). 
 7. NO
CONFLICTING AGREEMENT OR OBLIGATION. I represent that my performance of all the terms of this Agreement and as an employee of the Company does not and will not breach any agreement or
obligation of any kind made prior to my employment by the Company, including agreements or obligations I may have with prior employers or

 

 
entities for which I have provided services. I have not entered into, and I agree I will not enter into, any agreement or obligation either written or oral in conflict herewith. 

8. RETURN OF COMPANY DOCUMENTS. When I leave the employ of the Company, I will deliver
to the Company any and all drawings, notes, memoranda, specifications, devices, formulas, and documents, together with all copies thereof, and any other material containing or disclosing any Company Inventions, Third Party Information or Proprietary
Information of the Company. I further agree that any property situated on the Company’s premises and owned by the Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company
personnel at any time with or without notice. Prior to leaving, I will cooperate with the Company in completing and signing the Company’s termination statement. 
 9. LEGAL AND EQUITABLE REMEDIES. I recognize that in the course of employment with the Company, I will have access to Proprietary
Information, to Third Party Information, and to employees, consultants, contractors, clients, and customers of the Company. I also recognize that the services I will be employed to provide are personal and unique. I understand that because of this
the Company may sustain irreparable injury if I violate this Agreement. In order to limit or prevent such irreparable injury, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or
other equitable relief, without bond and without prejudice to any other rights and remedies that the Company may have for a breach of this Agreement. 
 10. NOTICES. Any notices required or permitted hereunder shall be given to the appropriate party at the address specified below or at such other address as the party shall specify in
writing. Such notice shall be deemed given upon personal delivery to the appropriate address or if sent by certified or registered mail, three (3) days after the date of mailing. 
 11. NOTIFICATION OF NEW EMPLOYER. In the event that I leave the employ of the Company, I authorize the Company to provide notice of my
rights and obligations under this Agreement to my subsequent employer and to any other entity or person to whom I provide services.

 12. GENERAL PROVISIONS. 

12.1 Governing Law; Consent to Personal Jurisdiction. This Agreement will be governed by and construed according to the laws of the State of
Maryland, as such laws are applied to agreements entered into and to be performed entirely within Maryland between Maryland residents. I hereby expressly consent to the personal jurisdiction of the state and federal courts for Howard County,
Maryland in any lawsuit filed there against me by Company arising from or related to this Agreement. 
 12.2 Severability. In case any
one or more of the provisions, subsections, or sentences contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other
provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. Moreover, if any one or more of the provisions contained in this Agreement shall for any
reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as it shall then appear.

 12.3 Successors and Assigns. This Agreement will be binding upon my heirs, executors, administrators and other legal representatives
and will be for the benefit of the Company, its successors, and its assigns. 
 12.4 Survival. The provisions of this Agreement shall
survive the termination of my employment and the assignment of this Agreement by the Company to any successor in interest or other assignee. 

12.5 Employment At-Will. I agree and understand that I am employed at-will, and that nothing in this Agreement shall change this at-will status or
confer any right with respect to continuation of employment by the Company, nor shall it interfere in any way with my right or the Company’s right to terminate my employment at any time, with or without cause. 

12.6 Waiver. No waiver by the Company of any breach of this Agreement shall be a waiver of any preceding or succeeding breach. No waiver by the
Company of any right under this Agreement shall be construed as a waiver of any other right. The Company shall not be required to give notice to enforce strict adherence to all terms of this Agreement.

 

 12.7 Entire Agreement. The obligations pursuant to Sections 1 and 2 of this Agreement shall apply to
any time during which I was previously employed, or am in the future employed, by the Company as a consultant if no other agreement governs nondisclosure and assignment of inventions during such period. This Agreement is the final, complete and
exclusive agreement of the parties with respect to the subject matter hereof and supersedes and merges all prior agreements or discussions between us on this subject matter. No modification of or amendment to this Agreement, nor any waiver of any
rights under this Agreement, will be effective unless in writing and signed by the party to be charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement. 

This Agreement shall be effective as of the first day of my employment with the Company, specifically: April 8, 2013. 

I HAVE READ THIS AGREEMENT CAREFULLY AND
UNDERSTAND ITS TERMS. I HAVE COMPLETELY FILLED OUT EXHIBIT A TO THIS AGREEMENT.

 EXHIBIT 2 

APPLICANT DISCLOSURE STATEMENT 
 In consideration of my employment or continued employment by Sourcefire, Inc. (the “Company”), and the compensation now and hereafter paid to me, I hereby agree as follows: 

1. Nondisclosure of Confidential Information. I acknowledge that I have not been asked to disclose and am not providing information which would be
considered as “confidential information” belonging to my former employer(s) to the Company during the employment application and hiring process, other than to the limited extent that a limited disclosure of such information may be
necessary to identify whether related issues may exist if I became employed by the Company. 
 2. Existing Employment Agreements. Except
as set forth below, I am aware of no current or prior employment agreements between me and my current or former employers, including but not limited to any employee code of conduct, noncompetition, non solicitation or nondisclosure agreements, which
would restrict or otherwise may adversely affect my accepting new employment with the Company. To the extent I have identified any such agreements, I agree to provide copies to the Company before my hiring process is completed so that they can be
reviewed for this purpose. To the extent such agreements exist, they are identified as follows: 

			
	  
	  	
	  
	  	

 My performance of my expected job duties at the Company will not breach any of these agreements, including as to any
agreement to keep in confidence confidential, proprietary and trade secret information that I may have acquired during my previous employment. 

3. Non-delivery of Confidential Information. I agree that, if I am offered and accept employment with the Company, I will not bring with me to my
new employment any items of “confidential information” from my former employer(s), and will not engage in any activities that would violate any employment or other agreements I may have with such employer(s). 

4. Non-removal of Confidential Information. I further acknowledge that, in preparation for engaging in the hiring process with the Company, I have
not removed any written, electronic or other materials containing “confidential information” of my current employer, whether or not such would assist me according to my understanding of the job position(s) for which I am being considered
by the Company. 
 I HAVE READ THIS AGREEMENT CAREFULLY AND UNDERSTAND ITS TERMS.
