NOW, THEREFORE, in consideration of the promises and the mutual covenants herein contained, the Parties hereby agree as follows:

1.             Duties and Responsibilities.

1.1          Position.  Executive shall serve as the Company’s Chairman and Chief Executive Officer. During the term of Executive’s employment with the Company, Executive will devote Executive’s diligent efforts and substantially all of Executive’s business time and attention to the business of the Company, except for approved vacation periods and reasonable periods of illness or other incapacities permitted by the Company’s general employment policies.  During the Employment Period (as defined below) executive shall serve as a member of the Board and as its Chairman, and the Board shall nominate Executive to stand for reelection, subject to election by the Company’s stockholders in accordance with the Company’s Certificate of Incorporation and Bylaws.  During the Employment Period, Executive shall not be paid a fee for serving as a member of the Board. The Company shall reimburse Executive for reasonable expenses incurred by Executive in connection with his service as a member of the Board in accordance with the Company’s expense reimbursement policies.

1.2          Duties and Location.  Executive shall perform such duties as are required by the Company’s Board of Directors (the “Board”), to whom Executive will report.  Executive’s primary office location shall be the Company’s Santa ▇▇▇▇▇▇▇ office.  The Company reserves the right to reasonably require Executive to perform Executive’s duties at places other than Executive’s primary office location from time to time, and to require reasonable business travel.  Executive shall devote substantially all of Executive’s business time and attention to the performance of Executive’s duties hereunder and shall not engage in any other business, profession or occupation for compensation or otherwise that would conflict or interfere with the rendition of such services, either directly or indirectly; provided that nothing in this Agreement shall preclude Executive from (i) managing personal investments, (ii) serving on civic or charitable boards or committees, (iii) engaging in business or professional activities for compensation from a third party, for 40 or fewer hours per calendar year, so long as such activities do not compete with the Company, and (iv) with the prior approval from the Board (not to be unreasonably withheld or delayed) serving on the board of directors of one other for-profit company that does not compete with the Company, so long as all such activities described in clauses (i) through (iv) herein do not materially interfere with the performance of Executive’s duties and responsibilities under this Agreement.  Executive has provided to the Board a written list of all boards of directors (whether for-profit or non-profit) of which he is a member.

1

1.3          Policies and Procedures.  The employment relationship between the Parties shall be governed by the general employment policies and practices of the Company, except that when the terms of this Agreement differ from or are in conflict with the Company’s general employment policies or practices, this Agreement shall control.

2.             Compensation.

2.1          Salary.  As of the Effective Date, Executive’s current base salary shall be payable at the annualized rate of $600,000.00 per year (the “Base Salary”), subject to standard payroll deductions and withholdings and payable in accordance with the Company’s regular payroll schedule.  The Base Salary may be increased in the sole and absolute discretion of the Board but may not be decreased during the Employment Period. In the event of any increase as permitted by this Section 2, the Base Salary for all purposes under this Agreement shall be the increased amount in effect from time to time.

2.2          Bonus.  Executive shall be provided with a signing bonus of $100,000 within thirty (30) days following the Effective Date.  For each full calendar year during the Employment Period, Executive shall be eligible for an annual discretionary bonus of up to 75% of Executive’s Base Salary (the “Target Bonus”), with the actual bonus amount (the “Annual Bonus”) determined by the Compensation Committee of the Board (the “Committee”) and communicated in writing to Executive, which Annual Bonus shall be based upon the achievement of specific performance goals as established by the Committee in good faith consultation with the Executive, and the Annual Bonus for the 2016 calendar year shall be established no later than March 1, 2016.  For the partial 2015 calendar year, Executive shall be eligible for a discretionary performance-based bonus of up to $50,000.00, based on the Board’s evaluation of his performance during such time period. Except as otherwise set forth above, whether Executive receives an Annual Bonus for any given year, and the amount of any such Annual Bonus, will be determined by the Committee in its sole discretion based upon the Company’s and Executive’s achievement of objectives and milestones to be determined on an annual basis by the Committee in good faith consultation with the Executive.  Executive must remain an active employee through the end of any given calendar year in order to earn an Annual Bonus for that year and any such bonus will be paid prior to February 15 of the year following the year in which Executive’s right to such amount became vested.  Executive will not be eligible for, and will not earn, any Annual Bonus (including a prorated bonus) if Executive’s employment terminates for any reason before the end of the calendar year, except as expressly contemplated in Section 6 below.

2.3          Equity Award.  Subject to the approval of the Board, (i) concurrent with the Effective Date, Executive shall be granted (A) a nonqualified stock option to purchase 621,931 shares of the Company’s common stock at a per share exercise price equal to the fair market value (as determined based on the terms of the equity plan pursuant to which it is granted) of the Company’s common stock on the grant date and with a ten (10) year term, and (B) a restricted stock unit award covering 17,993 shares of the Company’s common stock, and (ii) on January 1, 2016, Executive shall be granted an additional nonqualified stock option to purchase 241,753 shares of the Company’s common stock at a per share exercise price equal to the fair market value (as determined based on the terms of the equity plan pursuant to which it is granted) of the Company’s common stock on the grant date and with a ten (10) year term.  The stock options shall vest in equal monthly installments over a forty-eight (48) month period commencing on the first month anniversary of the Effective Date and the restricted stock units shall vest in equal three (3) month installments over a forty-eight (48) month period commencing on the three (3) month anniversary of the Effective Date. The options and restricted stock units shall be governed by the Company’s standard form of stock option agreement and restricted stock unit agreement, respectively, and subject to the terms and conditions of this Agreement.

3.             Company Benefits.  Executive shall be entitled to participate in all employee benefit programs for which Executive is eligible under the terms and conditions of the benefit plans that may be in effect from time to time and provided by the Company to its senior executive employees, provided that such benefits shall be made available on the Effective Date without regard to any waiting period, to the extent permitted by the terms of the benefit plans and applicable law.  The Company reserves the right to cancel or change the benefit plans or programs it offers to its employees at any time. Executive and the Company shall enter into the Company’s standard Indemnification Agreement, which Indemnification Agreement shall be effective as of the Effective Date.  The Company shall reimburse Executive for any necessary and reasonable, out-of-pocket Relocation Expenses (as defined below) that are actually incurred by Executive. For purposes of this Section 3, “Relocation Expenses” shall mean (i) travel, lodging, and meal expenses for Executive and his spouse and children for house hunting trips or relocation to Executive’s new principal residence, (ii) expenses for moving the household goods, personal effects, and automobiles of Executive and his spouse and children from Executive’s current principal residence to his residence located near the Company, and (iii) brokerage commission expenses incurred by Executive in connection with the sale of Executive’s current principal residence, provided the expenses described in clause (i), (ii) or (iii) are directly related to the establishment of Executive’s residence located near the Company in connection with Executive’s employment with the Company, and such Relocation Expenses shall be reimbursed only if incurred by Executive not later than December 31, 2016.  The Company shall pay such reimbursements and other payments upon presentation of an itemized account and appropriate supporting documentation in accordance with the Company’s expense reimbursement procedures.  In addition, the Company agrees to promptly reimburse Executive for the reasonable legal fees incurred by Executive in the preparation and negotiation of this Agreement.

4.             Paid Time Off.  Executive shall be entitled to accrue and use paid time off in accordance with the terms of the Company’s policies and practices, provided, however, that in no event will Executive’s vacation accrual rate be lower than twenty (20) days per year.

5.             Expenses.  The Company will reimburse Executive for reasonable and normal airfare, car rental, travel, local transportation, entertainment, or other expenses incurred by Executive in furtherance or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

6.             Termination of Employment; Severance.

6.1          At-Will Employment.  Executive’s employment relationship is at-will.  Either Executive or the Company may terminate the employment relationship at any time, with or without Cause or advance notice.  The period during which Executive’s employment continues in effect shall be referenced as the “Employment Period.”

6.2          Termination for Cause; Resignation; Death or Disability.

(a)                           The Company may terminate Executive’s employment with the Company at any time for Cause (as defined below).  Further, Executive may resign at any time, with or without Good Reason (as defined below).  Executive’s employment with the Company may also be terminated due to Executive’s death or disability.

(b)                           If Executive resigns for any reason, except as provided in Section 6.4 below, or the Company terminates Executive’s employment for Cause, or upon Executive’s death or disability, then (i) Executive will no longer vest in any equity awards, (ii) all payments of

3

compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already earned), and (iii) Executive will not be entitled to any severance benefits.  In addition, Executive shall resign from all positions and terminate any relationships as an employee, advisor, officer or director with the Company and any of its affiliates, each effective on the date of termination.

6.3          Termination without Cause.  In the event Executive’s employment with the Company is terminated by the Company without Cause (and other than as result of death or disability) prior to the closing of a Change in Control (as defined below) or more than twelve (12) months following the closing of a Change of Control, then provided such termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “Separation from Service”), and provided that Executive remains in compliance with the terms of this Agreement, the Company shall provide Executive with the following severance benefits (collectively, the “Severance Benefits”):

(a)           (X) in the event of a termination by the Company without Cause on or prior to the two-year anniversary of the Effective Date, the Company shall pay Executive (i) an amount equal to (twenty-four) 24 months of Executive’s then-current Base Salary paid in a lump sum, plus (ii) a lump sum amount equal to two (2) times the Annual Bonus, earned by Executive in connection with completion of the fiscal year prior to Executive’s Separation from Service, or (Y) in the event of a termination by the Company without Cause after the two-year anniversary of the Effective Date, the Company shall pay Executive (i) an amount equal to (twelve) 12 months of Executive’s then-current Base Salary paid in a lump sum, plus (ii) a lump sum amount equal to the Annual Bonus, earned by Executive in connection with completion of the fiscal year prior to Executive’s Separation from Service.

(b)           Provided that Executive timely elects continued coverage under COBRA, the Company shall pay Executive’s COBRA premiums to continue Executive’s coverage (including coverage for eligible dependents, if applicable) (“COBRA Premiums”) through the period (the “COBRA Premium Period”) starting on the Executive’s Separation from Service and ending on the earliest to occur of: (i) eighteen (18) months following Executive’s Separation from Service; (ii) the date Executive becomes eligible for group health insurance coverage through a new employer; or (iii) the date Executive ceases to be eligible for COBRA continuation coverage for any reason, including plan termination.  In the event Executive becomes covered under another employer’s group health plan or otherwise cease to be eligible for COBRA during the COBRA Premium Period, Executive must immediately notify the Company of such event.  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, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to Executive a taxable monthly payment in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s group health coverage in effect on the date of Executive’s employment termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made on the last day of each month regardless of whether Executive elects COBRA continuation coverage and shall end on the earlier of (x) the date upon which Executive obtains other employment or (y) the last day of the 18th calendar month following Executive’s Separation from Service date.

(c)           In the event of a termination by the Company without Cause (i) on or prior to the two-year anniversary of the Effective Date, the Company shall accelerate the vesting of that portion of all then-unvested Company equity awards granted to Executive that would have vested over the 12-month period following the date of Executive’s Separation from Service; or (ii) following the two-year anniversary of the Effective Date, the Company shall accelerate the vesting of that portion of all then-unvested Company equity awards granted to Executive such that all of Executive’s then-outstanding

4

unvested Company equity awards shall be deemed vested and exercisable as of Executive’s Separation from Service date.

6.4          Change in Control.

(a)           If the Company terminates Executive’s employment with the Company without Cause, or Executive resigns for Good Reason, in either case on or within twelve (12) months following the closing of a Change in Control (as defined below), and such termination represents a Separation from Service, then Executive shall be entitled to the Severance Benefits as set forth in Section 6.3.

(b)           In addition, if an acquiror does not assume or continue Executive’s then-unvested Company equity awards in connection with a Change in Control that also represents a Corporate Transaction (as defined in the Company’s 2014 Equity Incentive Plan), then all such awards shall accelerate in full and will be deemed vested and exercisable as of the closing of the Corporate Transaction.

7.             Conditions to Receipt of Severance Benefits.  The receipt of the Severance Benefits provided in Section 6.3 and Section 6.4 above, as applicable, will be subject to Executive signing and not revoking within the permitted timeframe a separation agreement and release of claims with the release of claims in substantially the form set forth on Exhibit A hereto (the “Separation and Release Agreement”) within the time period set forth therein, which shall not exceed fifty (50) days from the date of Executive’s Separation from Service (the “Release Period”).  No Severance Benefits will be paid or provided until the Separation and Release Agreement becomes effective.  If the Release Period described in the preceding sentence spans two calendar years, then payment of Severance Benefits will in any event commence in the second calendar year to the extent required to comply with Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”).  Executive shall also resign from all positions and terminate any relationships as an employee, advisor, officer or director with the Company and any of its affiliates, each effective on the date of termination.

8.             Section 409A.   It is intended that all of the severance benefits and other payments payable under this Agreement satisfy, to the greatest extent possible, the exemptions from the application of Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest extent possible as consistent with those provisions, and to the extent no so exempt, this Agreement (and any definitions hereunder) will be construed in a manner that complies with Section 409A.  For purposes of Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), Executive’s right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment.  Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by the Company at the time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other agreement with the Company are deemed to be “deferred compensation”, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments shall not be provided to Executive prior to the earliest of (i) the expiration of the six-month period measured from the date of Executive’s Separation from Service with the Company, (ii) the date of Executive’s death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation.  Upon the first business day following the expiration of such time period, all payments

5

deferred pursuant to this Paragraph shall be paid in a lump sum to Executive, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement. No interest shall be due on any amounts so deferred.

9.             Parachute Payments.  If any payment or benefit (including payments and benefits pursuant to this Agreement) that Executive would receive in connection with a Change in Control from the Company or otherwise (“Transaction Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Company shall cause to be determined, before any amounts of the Transaction Payment are paid to Executive, which of the following two alternative forms of payment would result in Executive’s receipt, on an after-tax basis, of the greater amount of the Transaction Payment notwithstanding that all or some portion of the Transaction Payment may be subject to the Excise Tax: (1) payment in full of the entire amount of the Transaction Payment (a “Full Payment”), or (2) payment of only a part of the Transaction Payment so that Executive receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”). For purposes of determining whether to make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all applicable federal, state and local income and employment taxes and the Excise Tax (all computed at the highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes). If a Reduced Payment is made, (x) Executive shall have no rights to any additional payments and/or benefits constituting the Transaction Payment, and (y) reduction in payments and/or benefits shall occur in the manner that results in the greatest economic benefit to Executive as determined in this paragraph. If more than one method of reduction will result in the same economic benefit, the portions of the Transaction Payment shall be reduced pro rata. Unless Executive and the Company otherwise agree in writing, any determination required under this section shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this section, the Accountants 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. Executive and the Company shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this section as well as any costs incurred by Executive with the Accountants for tax planning under Sections 280G and 4999 of the Code.

10.          Definitions.

10.1        Cause.  For purposes of this Agreement, “Cause” for termination will mean:  (a) Executive’s willful and continued failure substantially to perform his duties and responsibilities to the Company hereunder in accordance with the lawful instructions of the Board, or a willful, material violation of a material policy of the Company that has caused or is reasonably expected to result in material injury to the Company, in either case which, if curable, Executive fails to cure within thirty (30) business days following written notice from the Board; (b) Executive’s commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably expected to result in material injury to the Company; (c) Executive’s willful breach of any of his obligations under any written agreement or covenant with the Company, which, if curable, Executive fails to cure within thirty (30) business days following written notice from the Board; or (d) Executive’s material and willful violation of a federal or state law or regulation applicable to the business of the Company that has caused or is reasonably expected to result in material injury to the Company.

6

10.2        Change in Control.  For purposes of this Agreement, “Change in Control” shall have the meaning provided in the Company’s 2014 Equity Incentive Plan.

10.3        Corporate Transaction.  For purposes of this Agreement, “Corporate Transaction” shall have the meaning provided in the Company’s 2014 Equity Incentive Plan.

10.4        Good Reason.  For purposes of this Agreement, Executive shall have “Good Reason” for resignation from employment with the Company if any of the following actions are taken by the Company without Executive’s affirmative prior written consent to such adverse change (which specifically acknowledges Executive’s waiver of the Good Reason condition with respect to the individual action that would otherwise form the basis of a resignation for Good Reason):  (a) a material reduction in Executive’s base salary, bonus opportunity or benefits; (b) a material reduction in Executive’s title, duties, responsibilities and/or authority; or (c) relocation of Executive’s principal place of employment to a place other than Santa Barbara, California.  In order to resign for Good Reason, Executive must provide written notice to the Board within thirty (30) days after the first occurrence of the event giving rise to Good Reason setting forth the basis for Executive’s resignation, allow the Company at least thirty (30) days from receipt of such written notice to cure such event, and if such event is not reasonably cured within such period, Executive must resign from all positions Executive then holds with the Company not later than sixty (60) days after the expiration of the cure period.

11.          Proprietary Information Obligations. Regardless of the reason of Executive’s termination of employment with the Company, Executive will continue to comply with the Employee Confidentiality, Inventions and Non-Interference Agreement dated as of the Effective Date (the “Confidentiality Agreement”).

12.          No Adverse Interests.  Executive agrees not to intentionally or knowingly acquire, assume or participate in, directly or indirectly, any position, investment or interest known by Executive to be adverse or antagonistic to the Company, its business or prospects, financial or otherwise.

13.          Non-Solicitation.  Executive agree that during the period of employment with the Company and for twelve (12) months after the date Executive’s employment is terminated for any reason, Executive will not, either directly or through others, solicit or encourage or attempt to solicit or encourage any employee, independent contractor, or consultant of the Company to terminate his or her relationship with the Company in order to become an employee, consultant or independent contractor to or for any other person or entity.

14.          Dispute Resolution.  To ensure the timely and economical resolution of disputes that may arise in connection with Executive’s employment with the Company, Executive and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement, breach, performance, negotiation, execution, or interpretation of this Agreement, Executive’s employment, or the termination of Executive’s employment, including but not limited to statutory claims, shall be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in Los Angeles, California, conducted by JAMS, Inc. (“JAMS”) under the then applicable JAMS rules (which can be found at the following web address: ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇▇▇▇▇▇).  By agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding.  The Company acknowledges that Executive will have the right to be represented by legal counsel at any arbitration proceeding.  The arbitrator shall:  (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award.  The Company will pay the arbitrator’s fees and any other fees,

7

costs or expenses unique to arbitration, including the filing fee, the fees and costs of the arbitrator, and rental of a room to hold the arbitration hearing. However, if Executive is the party initiating the claim, Executive shall be responsible for contributing an amount equal to the filing fee to initiate a claim in the court of general jurisdiction in the State of California. The Arbitrator shall award reasonable legal fees and/or costs to the prevailing party in any dispute subject to arbitration under this Agreement, to the extent permitted by applicable law.  Nothing in this Agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration.  Any awards or orders in such arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction.

15.          General Provisions.

15.1        Notices.  Any notices provided must be in writing and will be deemed effective upon the earlier of personal delivery (including personal delivery by fax) or the next day after sending by overnight carrier, to the Company at its primary office location and to Executive at the address as listed on the Company payroll.

15.2        Severability.  Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction to the extent possible in keeping with the intent of the parties.

15.3        Waiver.  Any waiver of any breach of any provisions of this Agreement must be in writing to be effective, and it shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement.

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

Each party expressly waives and relinquishes all rights and benefits under this section and any law or legal principle of similar effect in any jurisdiction with respect to claims released hereby.

13.          NO ADMISSIONS.  The parties hereto hereby acknowledge that this is a compromise settlement of various matters, and that the promised payments in consideration of this Agreement shall not be construed to be an admission of any liability or obligation by either party to the other party or to any other person whomsoever.

14.          ENTIRE AGREEMENT.  This Agreement constitutes the complete, final and exclusive embodiment of the entire Agreement between you and the Company with regard to the subject matter hereof.  It is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein.  It may not be modified except in writing signed by you and the Chairman of the Board of the Company.  Each party has carefully read this Agreement, has been afforded the opportunity to be advised of its meaning and consequences by his or its respective attorneys, and signed the same of his or its free will.

15.          SUCCESSORS AND ASSIGNS.  This Agreement shall bind the heirs, personal representatives, successors, assigns, executors, and administrators of each party, and inure to the benefit of each party, its agents, directors, officers, employees, servants, heirs, successors and assigns.

16.          APPLICABLE LAW.  This Agreement shall be deemed to have been entered into and shall be construed and enforced in accordance with the laws of the State of California as applied to contracts made and to be performed entirely within California.

17.          SEVERABILITY.  If a court or arbitrator of competent jurisdiction determines that any term or provision of this Agreement is invalid or unenforceable, in whole or in part, the remaining terms and provisions hereof shall be unimpaired.  Such court or arbitrator will have the authority to modify or replace the invalid or unenforceable term or provision with a valid and enforceable term or provision that most accurately represents the parties’ intention with respect to the invalid or unenforceable term or provision.

18.          INDEMNIFICATION.  You will indemnify and save harmless the Company from any loss incurred directly or indirectly by reason of the falsity or inaccuracy of any representation made herein.  The Company will indemnify and save harmless you from any loss incurred directly or indirectly by reason of the falsity or inaccuracy of any representation made herein.  The Company and you acknowledge and agree that the terms of the Company’s standard form of indemnification agreement for members of the Board and executive officers of the Company

have applied to you in your role as an executive officer of the Company, and the Company hereby affirms its continuing agreements and obligations as set forth in such indemnification agreement with you.

19.          AUTHORIZATION.  You and the Company warrant and represent that there are no liens or claims of lien or assignments in law or equity or otherwise of or against any of the claims or causes of action released herein and, further, that each of them are fully entitled and duly authorized to give their complete and final general release and discharge.

20.          COUNTERPARTS.  This Agreement may be executed in two counterparts, each of which shall be deemed an original, all of which together shall constitute one and the same instrument.

21.          SECTION HEADINGS.  The section and paragraph headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

22.          PHOTOCOPIES.  A photocopy of this executed Agreement shall be as valid, binding, and effective as the original Agreement.

23.          SECTION 409A.  It is intended that all of the benefits and payments payable under this Agreement satisfy, to the greatest extent possible, an exemption from Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), and this Agreement will be construed to the greatest extent possible as consistent with those exemptions, and to the extent not so exempt, this Agreement (and any definitions hereunder) will be construed to the greatest extent possible in a manner that complies with Section 409A. For purposes of Section 409A, your right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this Agreement, if you are deemed by the Company at the time of your separation from service to be a “specified employee” for purposes of Section 409A, and if any of the payments upon separation from service set forth herein and/or under any other agreement with the Company are deemed to be “deferred compensation”, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Section 409A and the related adverse taxation under Section 409A, such payments shall not be provided to you prior to the earliest of (i) the expiration of the six-month period measured from the date of your separation from service, (ii) the date of your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. If the release revocation period spans two calendar years, payments will commence in the second of those two calendar years to the extent required to comply with Section 409A.
