Chris Lien

[PRIVATE ADDRESS]

Dear Chris:

This letter confirms the agreement (“Agreement”) between you and Marin Software Incorporated (the “Company”) concerning the terms of your transition and separation from employment and offers you certain benefits, including severance benefits as set forth in that certain Severance and Change in Control Agreement between you and the Company dated April 19, 2013 and attached hereto as Exhibit A (the “Severance Agreement”), conditioned upon your provision of a general release of claims and covenant not to sue upon the Separation Date (defined below) as provided herein. If you agree to the terms outlined herein, please sign and return this Agreement to me in the timeframe outlined below.

1. Separation from Employment: This Agreement confirms that your last day of employment will be September 30, 2015 (the “Separation Date”), subject to the at-will nature of your employment, as described in Paragraph 2(d), below. The Company has discussed with you the terms under which it would offer to continue your employment through the Separation Date.

2. Continued Employment; Other Release Consideration: In exchange for your agreement to the general release and waiver of claims and covenant not to sue set forth below and your other promises herein, the Company agrees to continue your employment on the following terms:

a. Transition Period and Services: Between now and the Separation Date (the “Transition Period”), you agree to carry out the duties and responsibilities of your position, and to provide other transition services as may reasonably be requested by the Company, including transition of the responsibilities, duties, and knowledge relative to your position (the “Transition Services”). During the Transition Period, you will maintain a full-time schedule.

b. Compensation and Benefits: During the Transition Period, the Company will continue to pay you your current base salary and you will continue to be eligible to participate in benefits customarily afforded to other employees, including participation in the Company-sponsored health benefits plan and continued vesting of options, to the fullest extent allowed by the governing plans, agreements, or policies. You will be reimbursed for all reasonable and documented business expenses incurred in your service through the Separation Date in accordance with the Company’s governing business expense reimbursement policies. Your final expense reimbursement statement should be submitted no later than 45 days after the Separation Date, and will be paid within 30 days thereafter.

c. Severance Benefits: In exchange for your agreement to the general release and waiver of claims and covenant not to sue set forth in Exhibit B (the “Second Release”), and your other promises herein, the Company agrees to provide you the severance benefits set forth in Section 2 of the Severance Agreement, on the terms and conditions set forth therein. As an additional severance benefit, subject to your satisfaction of the foregoing Second Release requirement, the Company will pay you a bonus for your services during the current fiscal year (prorated based on your partial year of service), to be paid in 2016 at the same time the Company pays bonuses to other Company executives. The amount of your bonus shall be determined by the Company’s Compensation Committee in its reasonable and good faith discretion based on the performance objectives now in effect, and shall be paid subject to applicable payroll deductions and withholdings.

d. At-Will Employment; Earlier Separation From Employment: During the Transition Period, your employment with the Company will remain at-will, meaning either you or the Company may accelerate the effective date of your separation with or without notice or reason. Notwithstanding the at-will nature of your employment, you will be entitled to all benefits and promises provided under this Agreement unless your employment is terminated by the Company terminated before September 30, 2015 for Cause, as such term is defined in the Severance Agreement. As of the Separation Date,, you will resign from all positions you hold with the Company (other than as a member of the Board of Directors of the Company (the “Board”)) and its subsidiaries, including, without limitation, Executive Chair, and any positions on the board of directors of any subsidiary of the Company, and you will relinquish any power of attorney given to you by the Company or its subsidiaries.

READ, UNDERSTOOD AND AGREED

EXHIBIT A

SEVERANCE AND CHANGE IN CONTROL AGREEMENT DATED APRIL 19, 2013

SEVERANCE AND CHANGE IN CONTROL AGREEMENT

This Severance and Change in Control Agreement is entered into as of April 19, 2013 (the “Effective Date”) by and between Christopher A. Lien (the “Executive”) and MARIN SOFTWARE INCORPORATED, a Delaware corporation (the “Company”).

Except to the extent renewed as set forth in this Section l, this Agreement shall terminate the earlier of June 30, 2016 (the “Expiration Date”) or the date the Executive’s employment with the Company terminates for a reason other than a Qualifying Termination as described in Section 4(e); however, if a definitive agreement relating to a Change in Control has been signed by the Company on or before June 30, 2016, then this Agreement shall remain in effect through the earlier of:

(a) The date the Executive’s employment with the Company terminates for a reason other than a Qualifying Termination as described in Section 4(e) or

(b) The date the Company has met all of its obligations under this Agreement following a termination of the Executive’s employment with the Company.

This Agreement shall renew automatically and continue in effect for three year periods measured from the initial Expiration Date, unless the Company provides Executive notice of non-renewal at least 90 days prior to the date on which this Agreement would otherwise expire.

(a) Severance Payment. If the Executive’s employment is terminated by the Company without Cause and Executive has a Separation that is not a Qualifying Termination under Section 3, then, subject to Section 4 below, the Company shall pay the Executive nine (9) months of his or her monthly base salary (at the rate in effect immediately prior to the actions that resulted in the Separation). Such severance payment shall be paid in accordance with the Company’s standard payroll procedures. The Executive will receive his or her severance payment in a cash lump-sum which will be made on the sixtieth (60^th) day following the Separation.

(b) Health Care Benefit. If the Executive is eligible for the severance benefit set forth in Section 2(a) above, and if the Executive elects to continue his or her health insurance coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) following the termination of his or her employment, then the Company shall pay the Executive’s monthly premium under COBRA until the earliest of (i) the close of the nine-month period following cessation of his or her employment or (ii) the expiration of the Executive’s continuation coverage under COBRA.

(c) Special Cash Payments in Lieu of COBRA Premiums. Notwithstanding the foregoing, if the Company determines, in its sole discretion, that it cannot pay the COBRA premiums without a substantial risk of violating applicable law (including Section 2716 of the Public Health Service Act), the Company instead shall pay to the Executive, on the first day of each calendar month, a fully taxable cash payment equal to the applicable COBRA premiums for that month (including premiums for the Executive and the Executive’s eligible dependents who have elected and remain enrolled in such COBRA coverage), subject to applicable tax withholdings (such amount, the “Special Cash Payment”), for the remainder of the period the Executive remains eligible for the benefit under Section 2(b) above. The Executive may, but is not obligated to, use such Special Cash Payments toward the cost of COBRA premiums. In the event the Company opts for the Special Cash Payments, then on the sixtieth (60^th) day following the Separation, the Company will make the first payment to the Executive under this Section, in a lump sum, equal to the aggregate Special Cash Payments that the Company would have paid through such date had the Special Cash Payments commenced on the first day of the first month following the Separation through such sixtieth (60^th) day, with the balance of the Special Cash Payments paid monthly thereafter.

(a) Severance Payment. If the Executive is subject to a Qualifying Termination, then, subject to Section 4 below, the Company shall pay the Executive nine (9) months of his or her monthly base salary (at the rate in effect immediately prior to the actions that resulted in the Qualifying Termination). Such severance payment shall be paid in accordance with the Company’s standard payroll procedures. The Executive will receive his or her severance payment in a cash lump-sum which will be made on the sixtieth (60^th) day following the Separation.

(b) Equity. Each of Executive’s then outstanding unvested Equity Awards, including awards that would otherwise vest only upon satisfaction of performance criteria, shall accelerate and become vested and exercisable with respect to 100% of the then

unvested shares subject thereto. “Equity Awards” means all options to purchase shares of the Company common stock as well as any and all other stock-based awards granted to the Executive, including but not limited to stock bonus awards, restricted stock, restricted stock units or stock appreciation rights. Subject to Section 4, the accelerated vesting described above shall be effective as of the Separation. In the event of a Qualifying Termination preceding the consummation of the Change in Control, Executive’s Equity Awards shall not be cancelled but shall remain outstanding until the earlier of (i) the closing of the Change in Control or (ii) three months after Executive’s Separation. If the Change in Control closes within three (3) months of Executive’s Separation, then Executive shall receive the benefits set forth in this Section 3(b) as of the date of closing of the Change in Control.

(c) Health Care Benefit. If the Executive is subject to a Qualifying Termination, and if the Executive elects to continue his or her health insurance coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) following the termination of his or her employment, then the Company shall pay the Executive’s monthly premium under COBRA until the earliest of (i) the close of the nine-month period following cessation of his or her employment or (ii) the expiration of the Executive’s continuation coverage under COBRA.

(d) Special Cash Payments in Lieu of COBRA Premiums. Notwithstanding the foregoing, if the Company determines, in its sole discretion, that it cannot pay the COBRA premiums without a substantial risk of violating applicable law (including Section 2716 of the Public Health Service Act), the Company instead shall pay to the Executive, on the first day of each calendar month, a fully taxable cash payment equal to the applicable COBRA premiums for that month (including premiums for the Executive and the Executive’s eligible dependents who have elected and remain enrolled in such COBRA coverage), subject to applicable tax withholdings (such amount, the “Special Cash Payment”), for the remainder of the period the Executive remains eligible for the benefit under Section 3(c) above. The Executive may, but is not obligated to, use such Special Cash Payments toward the cost of COBRA premiums. In the event the Company opts for the Special Cash Payments, then on the sixtieth (60^th) day following the Separation, the Company will make the first payment to the Executive under this Section, in a lump sum, equal to the aggregate Special Cash Payments that the Company would have paid through such date had the Special Cash Payments commenced on the first day of the first month following the Separation through such sixtieth (60^th) day, with the balance of the Special Cash Payments paid monthly thereafter.

(a) General Release. Any other provision of this Agreement notwithstanding, Executive shall not be entitled to the benefits of Section 2 or 3 above unless the Executive (i) has executed a general release (in a form prescribed by the Company) of all known and unknown claims that he or she may then have against the Company or persons affiliated with the Company and (ii) has agreed not to prosecute any legal action or other proceeding based upon any of such claims. The release must be in the form prescribed by the Company, without alterations. The Company will deliver the form to the Executive within 30 days after the Executive’s Separation. The Executive must execute and return the release within the time period specified in the form.

(b) Non-Competition. The Executive agrees that, during his or her employment with the Company, he or she shall not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company.

(c) Cooperation and Non-Disparagement. The Executive agrees that, during the six-month period following his or her cessation of employment, he or she shall cooperate with the Company in every reasonable respect and shall use his or her best efforts to assist the Company with the transition of Executive’s duties to his or her successor. The Executive further agrees that, during this six-month period, he or she shall not in any way or by any means disparage the Company, the members of the Company’s Board of Directors or the Company’s officers and employees.

(d) Accrued Compensation and Benefits. In connection with any termination of employment, the Company shall pay Executive’s earned but unpaid base salary and other vested but unpaid cash entitlements for the period through and including the termination of employment, including unused earned vacation pay and unreimbursed documented business expenses incurred by Executive prior to the date of termination (collectively “Accrued Compensation and Expenses”), as required by law and the applicable Company plan or policy. In addition, Executive shall be entitled to any other vested benefits earned by Executive for the period through and including the termination date of Executive’s employment under any other employee benefit plans and arrangements maintained by the Company, in accordance with the terms of such plans and arrangements, except as modified herein (collectively “Accrued Benefits”). Any Accrued Compensation and Expenses to which the Executive is entitled shall be paid to the Executive in cash as soon as administratively practicable after the termination, and, in any event, no later than two and one-half (2 1/2) months after the end of the taxable year of the Executive in which the termination occurs. Any Accrued Benefits to which the Executive is entitled shall be paid to the Executive as provided in the relevant plans and arrangement.

2

(a) “Cause” means (i) Executive’s continued refusal or material failure to perform Executive’s material duties reasonably expected of Executive in connection with his or her arrangement to provide services to the Company or any Parent or Subsidiary, as applicable; (ii) unprofessional, unethical or fraudulent conduct or conduct that materially discredits the Company or any Parent or Subsidiary, as applicable, or is materially detrimental to the reputation, character or standing of the Company or any Parent or Subsidiary, as applicable; (iii) dishonest conduct with respect to a material matter, or a deliberate attempt to do an injury to the Company or any Parent or Subsidiary, as applicable; (iv) Executive’s material breach of any material term of any agreement between Executive and; (v) a criminal act which would reflect badly on the Company or any Parent or Subsidiary, as applicable; (vi) Executive’s failure to cooperate with the Company in any investigation or formal proceeding; or (vii) Executive’s death or total disability (for these purposes Executive shall be deemed totally disabled if, in the judgment of a licensed physician, Executive is physically or mentally incapacitated or disabled or otherwise unable to fully discharge Executive’s duties as a service provider to the Company or any Parent or Subsidiary, as applicable, for a period of 180 consecutive days or for 180 days in any 365 calendar day period); provided that Executive must be provided with written notice of Executive’s termination for “Cause” and Executive must be provided with a 30-day period following Executive’s receipt of such notice to cure the event(s) that trigger “Cause” (if curable), with the Compensation Committee of the Company’s Board of Directors making the final determination whether Executive has cured any Cause.

(b) “Code” means the Internal Revenue Code of l986, as amended.

(c) “Change in Control” shall mean a Corporate Transaction, as such term is defined in the 2013 Equity Incentive Plan.

(d) “Good Reason” means Executive’s Employment by the Company or any Parent or Subsidiary, as applicable, is voluntarily terminated by Executive for any one or more of the following reasons: (i) a material diminution in the Executive’s authority, duties or responsibilities, provided, however, if by virtue of the Company being acquired and made a division or business unit of a larger entity following a Change in Control, Executive retains substantially similar authority, duties or responsibilities for such division or business unit of the acquiring corporation but not for the entire acquiring corporation, such reduction in authority, duties or responsibilities shall not constitute Good Reason for purposes of this sub-clause (d)(i); (ii) a 10% or greater reduction in his or her level of compensation, which will be determined based on an average of the Executive’s annual total target cash compensation (annual base salary plus target annual cash incentives) for the prior three calendar years or, if less, the number of years the Executive has been employed by the Company; or (iii) a relocation of Executive to a facility or a location that would increase Executive’s one-way commute by more than 35 miles from Executive’s then current place of employment, provided and only if such change, reduction or relocation is effected by the Company without Executive’s consent. For the Executive to receive the benefits under this Agreement as a result of a voluntary resignation under this subsection (d), all of the following requirements must be satisfied: (1) the Executive must provide notice to the Company of his or her intent to assert Good Reason within 120 days of the initial existence of one or more of the conditions set forth in subclauses (i) through (iii): (2) the Company will have 30 days from the date of such notice to remedy the condition and , if it does so, the Executive may withdraw his or her resignation or may resign with no benefits under this Agreement; and (3) any termination of employment under this provision must occur within six months of the initial existence of one or more of the conditions set forth in subclauses (i) through (iii). Should the Company remedy the condition as set forth above and then one or more of the conditions arises again within twelve months following the occurrence of a Change in Control, the Executive may assert Good Reason again subject to all of the conditions set forth herein.

(e) “Qualifying Termination” means a Separation as a result of (i) the Company terminates the Executive’s employment for any reason other than Cause or (ii) the Executive voluntarily resigns his or her employment for Good Reason, within twelve (12) months following a Change in Control or within three (3) months preceding a Change in Control if after a Potential Change in Control. A “Potential Change in Control” means the date of execution of a definitive agreement whereby the Company will consummate a Change in Control if such transaction is consummated. In the case of a termination following a Potential Change in Control and before a Change in Control, solely for purposes of benefits under this Agreement, the date of Separation will be deemed the date the Change in Control is consummated.

(f) “Separation” means a “separation from service,” as defined in the regulations under Section 409A of the Code.

(a) Company’s Successors. The Company shall require any successor (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets, by an agreement in substance and form satisfactory to the Executive, to assume this Agreement and to agree expressly to perform this Agreement in the same manner and to the same extent as the Company would be required to perform it in the absence of a succession. For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business and/or assets or which becomes bound by this Agreement by operation of law.

3

(b) Executive’s Successors. This Agreement and all rights of the Executive hereunder shall inure to the benefit of, and be enforceable by, the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

(a) Best After-Tax Result. In the event that any payment or benefit received or to be received by Executive pursuant to this Agreement or otherwise (“Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this subsection (a), be subject to the excise tax imposed by Section 4999 of the Code, any successor provisions, or any comparable federal, state, local or foreign excise tax (“Excise Tax”), then, subject to the provisions of Section 7(b) hereof, such Payments shall be either (A) provided in full pursuant to the terms of this Agreement or any other applicable agreement, or (B) provided as to such lesser extent which would result in no portion of such Payments being subject to the Excise Tax (“Reduced Amount”). whichever of the foregoing amounts, taking into account the applicable federal, state, local and foreign income, employment and other taxes and the Excise Tax (including, without limitation, any interest or penalties on such taxes), results in the receipt by Executive, on an after-tax basis, of the greatest amount of payments and benefits provided for hereunder or otherwise, notwithstanding that all or some portion of such Payments may be subject to the Excise Tax. Unless the Company and Executive otherwise agree in writing, any determination required under this Section shall be made by independent tax counsel designated by the Company and reasonably acceptable to Executive (“Independent Tax Counsel”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required under this Section, Independent Tax Counsel may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code; provided that Independent Tax Counsel shall assume that Executive pays all taxes at the highest marginal rate. The Company and Executive shall furnish to Independent Tax Counsel such information and documents as Independent Tax Counsel may reasonably request in order to make a determination under this Section. The Company shall bear all costs that Independent Tax Counsel may reasonably incur in connection with any calculations contemplated by this Section. In the event that Section 7(a)(ii)(B) above applies, then based on the information provided to Executive and the Company by Independent Tax Counsel, Independent Tax Counsel shall determine which and how much of the Payments (including the accelerated vesting of equity compensation awards) to be otherwise received by Executive shall be eliminated or reduced (as long as after such determination the value (as calculated by Independent Tax Counsel in accordance with the provisions of Sections 280G and 4999 of the Code) of the amounts payable or distributable to Executive equals the Reduced Amount). If the Internal Revenue Service (the “IRS”) determines that any Payment is subject to the Excise Tax, then Section 7(b) hereof shall apply, and the enforcement of Section 7(b) shall be the exclusive remedy to the Company.

(b) Adjustments. If, notwithstanding any reduction described in Section 7(a) hereof (or in the absence of any such reduction), the IRS determines that Executive is liable for the Excise Tax as a result of the receipt of one or more Payments, then Executive shall be obligated to surrender or pay back to the Company, within 120 days after a final IRS determination, an amount of such payments or benefits equal to the “Repayment Amount.” The Repayment Amount with respect to such payments shall be the smallest such amount, if any, as shall be required to be surrendered or paid to the Company so that Executive’s net proceeds with respect to such Payments (after taking into account the payment of the Excise Tax imposed on such Payments) shall be maximized. Notwithstanding the foregoing, the Repayment Amount with respect to such Payments shall be zero if a Repayment Amount of more than zero would not eliminate the Excise Tax imposed on such Payments or if a Repayment Amount of more than zero would not maximize the net amount received by Executive from the Payments. If the Excise Tax is not eliminated pursuant to this Section 7(b), Executive shall pay the Excise Tax.

(a) Section 409A. For purposes of Section 409A of the Code, if the Company determines that Executive is a “specified employee” under Code Section 409A(a)(2)(B)(i) at the time of a Separation, then (i) the severance benefits under Section 2 and 3, to the extent subject to Code Section 409A, will commence during the seventh month after the Executive’s Separation and (ii) will be paid in a lump sum on the earliest practicable date permitted by Section 409A(a)(2) of the Code. It is intended that each installment of the payments provided hereunder constitute separate “payments” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). It is further intended that payments hereunder satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code (and any state law of similar effect) provided under Treasury Regulation Section 1.409A- I(b)(4) (as a “short-term deferral”). To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision will be read in such a manner so that all payments hereunder comply with Section 409A of the Code.

ATTACHMENT 1

List of Assigned Technology

MARIN SOFTWARE INCORPORATED

EMPLOYEE INVENTION ASSIGNMENT AND

CONFIDENTIALITY AGREEMENT

In consideration of, and as a condition of my employment with Marin Software Incorporated, a Delaware corporation (the “Company”), I hereby represent to, and agree with the Company as follows:

1. Purpose of Agreement. I understand that the Company is engaged in a continuous program of research, development, production and marketing in connection with its business and that it is critical for the Company to preserve and protect its “Proprietary Information” (as defined in Section 7 below), its rights in “Inventions” (as defined in Section 2 below) and in all related intellectual property rights. Accordingly, I am entering into this Employee Invention Assignment and Confidentiality Agreement (this “Agreement”) as a condition of my employment with the Company, whether or not I am expected to create inventions of value for the Company.

2. Disclosure of Inventions. I will promptly disclose in confidence to the Company all inventions, improvements, designs, original works of authorship, formulas, processes, compositions of matter, computer software programs, databases, mask works and trade secrets that I make or conceive or first reduce to practice or create, either alone or jointly with others, during the period of my employment, whether or not in the course of my employment, and whether or not patentable, copyrightable or protectable as trade secrets (the “Inventions”).

3. Work for Hire; Assignment of Inventions. I acknowledge and agree that any copyrightable works prepared by me within the scope of my employment are “works for hire” under the Copyright Act and that the Company will be considered the author and owner of such copyrightable works. I agree that all Inventions that (i) are developed using equipment, supplies, facilities or trade secrets of the Company, (ii) result from work performed by me for the Company, or (iii) relate to the Company’s business or current or anticipated research and development (the “Assigned Inventions”), will be the sole and exclusive property of the Company and are hereby irrevocably assigned by me to the Company. Attached hereto as Exhibit A is a list describing all inventions, original works of authorship, developments and trade secrets which were made by me prior to the date of this Agreement, which belong to me and which are not assigned to the Company (“Prior Inventions”). If no such list is attached, I agree that it is because no such Prior Inventions exist. I acknowledge and agree that if I use any of my Prior Inventions in the scope of my employment, or include them in any product or service of the Company, I hereby grant to the Company a perpetual, irrevocable, nonexclusive, world-wide, royalty-free license to use, disclose, make, sell, copy, distribute, modify and create works based on, perform or display such Prior Inventions and to sublicense third parties with the same rights.

4. Labor Code Section 2870 Notice. I have been notified and understand that the provisions of Sections 3 and 5 of this Agreement do not apply to any Assigned Invention that qualifies fully under the provisions of Section 2870 of the California Labor Code, which states as follows:

ANY PROVISION IN AN EMPLOYMENT AGREEMENT WHICH PROVIDES THAT AN EMPLOYEE SHALL ASSIGN, OR OFFER TO ASSIGN, ANY OF HIS OR HER RIGHTS IN AN INVENTION TO HIS OR HER EMPLOYER SHALL NOT APPLY TO AN INVENTION THAT THE EMPLOYEE DEVELOPED ENTIRELY ON HIS OR HER OWN TIME WITHOUT USING THE EMPLOYER’S EQUIPMENT, SUPPLIES, FACILITIES, OR TRADE SECRET INFORMATION EXCEPT FOR THOSE INVENTIONS THAT EITHER: (1)RELATE AT THE TIME OF CONCEPTION OR REDUCTION TO PRACTICE OF THE INVENTION TO THE EMPLOYER’S BUSINESS, OR ACTUAL OR DEMONSTRABLY ANTICIPATED RESEARCH OR DEVELOPMENT OF THE EMPLOYER; OR (2) RESULT FROM ANY WORK PERFORMED BY THE EMPLOYEE FOR THE EMPLOYER. TO THE EXTENT A PROVISION IN AN EMPLOYMENT AGREEMENT PURPORTS TO REQUIRE AN EMPLOYEE TO ASSIGN AN INVENTION OTHERWISE EXCLUDED FROM BEING REQUIRED TO BE ASSIGNED UNDER CALIFORNIA LABOR CODE SECTION 2870(a), THE PROVISION IS AGAINST THE PUBLIC POLICY OF THIS STATE AND IS UNENFORCEABLE.

5. Assignment of Other Rights. In addition to the foregoing assignment of Assigned Inventions to the Company, I hereby irrevocably transfer and assign to the Company: (i) all worldwide patents, patent applications, copyrights, mask works, trade secrets and other intellectual property rights, including but not limited to rights in databases, in any Assigned Inventions, along with any registrations of or applications to register such rights; and (ii) any and all “Moral Rights” (as defined below) that I may have in or with respect to any Assigned Inventions. I also hereby forever waive and agree never to assert any and all Moral Rights I may have in or with respect to any Assigned Inventions, even after termination of my work on behalf of the Company. “Moral Rights” mean any rights to claim authorship of or credit on an Assigned Inventions, to object to or prevent the modification or destruction of any Assigned Inventions or Prior Inventions licensed to Company under Section 3, or to withdraw from circulation or control the

publication or distribution of any Assigned Inventions or Prior Inventions licensed to Company under Section 3, and any similar right, existing under judicial or statutory law of any country or subdivision thereof in the world, or under any treaty, regardless of whether or not such right is denominated or generally referred to as a “moral right.” Notwithstanding the foregoing, I will have the right to claim participation in the development, creation, or modification of the Assigned Inventions on my resume or in my curriculum vita; provided that I obtain Company’s approval for such disclosures before providing the disclosure to any third-party.

6. Assistance. I agree to assist the Company in every proper way to obtain for the Company and enforce patents, copyrights, mask work rights, trade secret rights and other legal protections for the Company’s Assigned Inventions in any and all countries. I will execute any documents that the Company may reasonably request for use in obtaining or enforcing such patents, copyrights, mask work rights, trade secrets and other legal protections. My obligations under this paragraph will continue beyond the termination of my employment with the Company, provided that the Company will compensate me at a reasonable rate after such termination for time or expenses actually spent by me at the Company’s request on such assistance. I appoint the Secretary of the Company as my attorney-in-fact to execute documents on my behalf for this purpose.

7. Proprietary Information. I understand that my employment by the Company creates a relationship of confidence and trust with respect to any information of a confidential or secret nature that may be disclosed to me by the Company or a third party that relates to the business of the Company or to the business of any parent, subsidiary, affiliate, customer or supplier of the Company or any other party with whom the Company agrees to hold information of such party in confidence (the “Proprietary Information”). Such Proprietary Information includes, but is not limited to, Assigned Inventions, marketing plans, product plans, business strategies, financial information, forecasts, personnel information, customer lists and data, and domain names.

8. Confidentiality. At all times, both during my employment and after its termination, I will keep and hold all such Proprietary Information in strict confidence and trust. I will not use or disclose any Proprietary Information without the prior written consent of the Company, except as may be necessary to perform my duties as an employee of the Company for the benefit of the Company. Upon termination of my employment with the Company, I will promptly deliver to the Company all documents and materials of any nature pertaining to my work with the Company and, upon the Company’s request, will execute a document confirming my agreement to honor my responsibilities contained in this Agreement. I will not take with me or retain any documents or materials or copies thereof containing any Proprietary Information.

9. No Breach of Prior Agreement. I represent that my performance of all the terms of this Agreement and my duties as an employee of the Company will not breach any invention assignment, proprietary information, confidentiality or similar agreement with any former employer or other party. I represent that I will not bring with me to the Company or use in the performance of my duties for the Company any documents or materials or intangibles of a former employer or third party that are not generally available to the public or have not been legally transferred to the Company.

10. Efforts; Duty Not to Compete. I understand that my employment with the Company requires my undivided attention and effort during normal business hours. While I am employed by the Company, I will not, without the Company’s express prior written consent, engage in any other employment or business that (i) directly competes with the current or future business of the Company; (ii) uses any Company information, equipment, supplies, facilities or materials; or (iii) otherwise conflicts with the Company’s business interest and causes a disruption of its operations.

11. Notification. I hereby authorize the Company to notify third parties, including, without limitation, customers and actual or potential employers, of the terms of this Agreement and my responsibilities hereunder.

12. Non-Solicitation of Employees/Consultants. During my employment with the Company and for a period of one (1) year thereafter, I will not directly or indirectly solicit away employees or consultants of the Company for my own benefit or for the benefit of any other person or entity.

13. Non-Solicitation of Suppliers/Customers. During and after the termination of my employment with the Company, I will not directly or indirectly solicit or otherwise take away customers or suppliers of the Company if, in so doing, I use or disclose any trade secrets or proprietary or confidential information of the Company. I agree that the non-public names and addresses of the Company’s customers and suppliers, and all other confidential information related to them, including their buying and selling habits and special needs, created or obtained by me during my employment, constitute trade secrets or proprietary or confidential information of the Company.

2

14. Name & Likeness Rights. I hereby authorize the Company to use, reuse, and to grant others the right to use and reuse, my name, photograph, likeness (including caricature), voice, and biographical information, and any reproduction or simulation thereof, in any form of media or technology now known or hereafter developed (including, but not limited to, film, video and digital or other electronic media), both during and after my employment, for any purposes related to the Company’s business, such as marketing, advertising, credits, and presentations.

15. Injunctive Relief. I understand that in the event of a breach or threatened breach of this Agreement by me the Company may suffer irreparable harm and will therefore be entitled to injunctive relief to enforce this Agreement.

16. Governing Law; Severability. This Agreement will be governed by and construed in accordance with the laws of the State of California, without giving effect to its laws pertaining to conflict of laws. If any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement.

17. Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered will be deemed an original, and all of which together shall constitute one and the same agreement.

18. Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement and understanding of the parties with respect to the subject matter of this Agreement, and supersede all prior understandings and agreements, whether oral or written, between or among the parties hereto with respect to the specific subject matter hereof.

19. Amendment and Waivers. This Agreement may be amended only by a written agreement executed by each of the parties hereto. No amendment of or waiver of, or modification of any obligation under this Agreement will be enforceable unless set forth in a writing signed by the party against which enforcement is sought. Any amendment effected in accordance with this section will be binding upon all parties hereto and each of their respective successors and assigns. No delay or failure to require performance of any provision of this Agreement shall constitute a waiver of that provision as to that or any other instance. No waiver granted under this Agreement as to any one provision herein shall constitute a subsequent waiver of such provision or of any other provision herein, nor shall it constitute the waiver of any performance other than the actual performance specifically waived.

20. Successors and Assigns; Assignment. Except as otherwise provided in this Agreement, this Agreement, and the rights and obligations of the parties hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives. The Company may assign any of its rights and obligations under this Agreement. No other party to this Agreement may assign, whether voluntarily or by operation of law, any of its rights and obligations under this Agreement, except with the prior written consent of the Company.

21. Further Assurances. The parties agree to execute such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement.

22. “At Will” Employment. I understand that this Agreement does not constitute a contract of employment or obligate the Company to employ me for any stated period of time. I understand that I am an “at will” employee of the Company and that my employment can be terminated at any time, with or without notice and with or without cause, for any reason or for no reason, by either the Company or myself. I acknowledge that any statements or representations to the contrary are ineffective, unless put into a writing signed by the Company. I further acknowledge that my participation in any stock option or benefit program is not to be construed as any assurance of continuing employment for any particular period of time. This Agreement shall be effective as of the first day of my employment by the Company, which is March 16, 2006.
