W I T N E S S E T H:

WHEREAS, the Company and Executive entered into an Amended and Restated Employment Agreement dated July 30, 2021 (the “Prior Agreement”);

WHEREAS, the Company desires to promote the Executive to President and Chief Executive Officer as of the Effective Date, and the Executive desires to accept this promotion as of the Effective Date; and

WHEREAS, the parties desire to enter into this Agreement, setting forth the terms and conditions of the Executive’s continued employment with the Company.

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

Employment.

(a)

Services. The Executive will be employed by the Company initially as its Chief Executive Officer and President, reporting to the Company’s Board of Directors (the “Board”), and shall perform such duties as are consistent with a position as Chief Executive Officer and President (the “Services”). The Executive agrees to perform such Services faithfully, to devote Executive’s full working time, attention and energies to the business of the Company and, while Executive remains employed and subject to the terms of this Agreement, not to engage in any other business activity that is in conflict with Executive’s duties and obligations to the Company.

(b)

Acceptance. The Executive hereby accepts such employment and agrees to render the Services.

Term. The Executive's employment under this Agreement shall commence as of the Effective Date and shall continue on an “at-will” basis until terminated pursuant to Section 8 of this Agreement (the “Term”).

Best Efforts. The Executive shall devote Executive’s full business time, attention and energies to the business and affairs of the Company and shall use Executive’s reasonable best efforts to advance the best interests of the Company and during the Term shall not be actively engaged in any other business activity, whether or not such business activity is pursued for gain, profit or other pecuniary advantage, that will interfere with the performance by the Executive of Executive’s duties hereunder or the Executive’s availability to perform such duties or that will adversely affect, or negatively reflect upon, the Company. The Executive shall not join any board

of directors of any for-profit entity or engage in outside consulting without the prior written consent of the Board (which consent shall not be unreasonably withheld). Notwithstanding the foregoing, Executive may serve on advisory boards for third-party charities and non-profit organizations (collectively the “Advisory Activities”) in each case provided that such Advisory activities (i) do not (either individually or collectively) conflict with or interfere with Executive’s Services hereunder or conflict with any of the Company’s policies; and (ii) are not competitive with any business or activity of the Company.

Directorship. So long as the Executive serves as the Company’s Chief Executive Officer, the Company shall include the Executive in the management slate for election as a director at every stockholders meeting and use its reasonable best efforts to cause the Executive to be elected as a voting member of its Board. The Executive agrees to accept such election and to serve as a member of the Company’s Board without any compensation therefor other than as specified in this Agreement. Upon termination of the Executive’s employment for any reason, or in the event the Executive ceases to remain the Company’s Chief Executive Officer for any other reason, the Executive will immediately resign from the Board unless otherwise unanimously requested by all the other members of the Board.

Compensation. During the Term, as full compensation for the performance by the Executive of his duties under this Agreement, the Company shall pay the Executive as follows:

(a)

Base Salary. The Company shall pay the Executive a base salary at the annualized rate of six hundred thousand dollars ($600,000). The base salary in effect at any given time is referred to herein as the “Base Salary.” Payment shall be made in accordance with the Company’s normal payroll practices, as they may be changed from time to time. The Base Salary will be reviewed by the Board, or a committee thereof, no less frequently than annually.

(b)

Annual Performance Bonus. The Executive shall be eligible to receive an annual performance-based bonus during the Term (the “Annual Performance Bonus”) targeted at sixty percent (60%) of Executive’s then current Base Salary based on the attainment by the Company and the Executive of certain performance objectives as established annually by the Board (or committee thereof) in consultation with Executive. The Annual Performance Bonus shall be payable in a single lump-sum as determined by the Board (or a committee thereof) in its sole discretion regarding the level of performance achieved. Except as otherwise provided in this Agreement, to earn any particular Annual Performance Bonus, the Executive must, in addition to satisfying the performance objectives, remain employed on the date the Annual Performance Bonus is paid; provided, further, that the Annual Performance Bonus will be paid no later than seventy-five (75) days after the end of the period to which the Annual Performance Bonus pertains.

(c)

[Reserved.]

(d)

Withholding. Amounts payable to the Executive under this Agreement, including Section 4 and Section 9, shall be net of all applicable federal, state and local taxes, social security and such other amounts as the Company may be required by law to withhold from such amounts.

(e)

Equity. From time to time, subject to and upon the approval by the Board (or a committee thereof), the Company may grant to the Executive equity awards to purchase or receive shares of common stock of the Company (the “Equity Awards”). The Equity Awards will contain such terms and conditions as may be approved by the Board (or a committee thereof).

(f)

Expenses. The Company shall provide the Executive with a corporate credit card for business use, and shall reimburse the Executive for all normal, usual and necessary expenses incurred by the Executive in furtherance of the business and affairs of the Company, including reasonable travel and entertainment, upon timely receipt by the Company of appropriate vouchers or other proof of the Executive’s expenditures and otherwise in accordance with any expense reimbursement policy as may from time to time be adopted by the Company.

(g)

Other Benefits. The Executive shall be entitled to all rights and benefits for which Executive shall be eligible under any benefit or other plans (including, without limitation, dental, medical, medical reimbursement and hospital plans, pension plans, employee stock purchase plans, profit sharing plans, bonus plans and other so-called “Fringe Benefits”) as the Company shall make available to its senior executives from time to time, subject to the terms of such plans. In addition, if applicable, the Company shall reimburse the Executive for Executive’s reasonable licensing fees, continuing professional education, and other professional dues upon timely receipt by the Company of appropriate vouchers or other proof of the Executive’s expenditures and otherwise in accordance with any expense reimbursement policy as may from time to time be adopted by the Company. The Company shall also name the Executive as a covered person under its Directors & Officers insurance policies.

(h)

Vacation. The Executive will be entitled to paid vacation in accordance with the Company’s vacation policy, as in effect from time to time.

Confidential Information and Inventions. The Executive agrees to continue to comply with the Company’s standard form of Proprietary Information and Inventions Agreement, as it may be amended from time to time (the “PIIA”).

Representations and Warranties.

(a)

The Executive hereby represents and warrants to the Company as follows:

(i)

Neither the execution or delivery of this Agreement nor the performance by the Executive of Executive’s duties and other obligations hereunder violate or will violate any statute, law, determination or award, or conflict with or constitute a default or breach of any covenant or obligation under (whether immediately, upon the giving of notice or lapse of time or both) any prior employment agreement, contract, or other instrument to which the Executive is a party or by which he is bound.

(ii)

The Executive has the full right, power and legal capacity to enter and deliver this Agreement and to perform Executive’s duties and other obligations hereunder. This Agreement constitutes the legal, valid and binding obligation of the Executive enforceable against him in accordance with its terms. No approvals or consents of any persons or entities are required for the Executive to execute and deliver this Agreement or perform Executive’s duties and other obligations hereunder.

(b)

The Company hereby represents and warrants to the Executive that this Agreement and the employment of the Executive hereunder have been duly authorized by and on behalf of the Company, including, without limitation, by all required action by the Board.

Termination. The Executive’s employment hereunder shall be terminated immediately upon the Executive’s death and may be otherwise terminated as follows:

(a)

The Executive’s employment hereunder may be terminated by the Company for Cause as determined by the Board. Any of the following actions by the Executive shall constitute “Cause”:

(i)

The willful and repeated failure or disregard or continuing refusal by the Executive to perform his duties hereunder;

(ii)

Any act of willful or intentional misconduct, or a grossly negligent act by the Executive having the effect of injuring, in a material way (as determined in good-faith by the Board), the business or reputation of the Company, including but not limited to, any officer, director, or executive of the Company;

(iii)

Willful misconduct by the Executive in carrying out his duties or obligations under this Agreement, including, without limitation, insubordination with respect to lawful directions received by the Executive from the Board having the effect of injuring, in a material way (as determined in good-faith by the Board), the business or reputation of the Company;

(iv)

The Executive’s indictment of any felony or a misdemeanor involving moral turpitude (including entry of a nolo contendere plea);

(v)

The determination by the Company, based upon clear and convincing evidence, after a reasonable and good-faith investigation by the Company following a written allegation by another employee of the Company, that the Executive engaged in some form of harassment or discrimination prohibited by law (including, without limitation, age, sex or race discrimination);

(vi)

Any intentional misappropriation of the property of the Company, or embezzlement of its funds or assets (whether or not a misdemeanor or felony);

(vii)

Material breach by the Executive of any of the provisions of the PIIA; and

(viii)

Material breach by the Executive of any provision of this Agreement other than those contained in the PIIA, which is not cured by the Executive within thirty (30) business days after notice thereof is given to the Executive by the Company.

Except for a failure, misconduct, breach, or refusal which, by its nature, cannot reasonably be expected to be cured, the Executive shall have ten (10) business days from the delivery of written notice by the Company within which to cure any acts constituting Cause, unless a longer cure period is provided in the act constituting Cause described above; provided however, that, if the

Company reasonably expects irreparable injury from a delay of ten (10) business days, the Company may give the Executive notice of such shorter period within which to cure as is reasonable under the circumstances, which may include the termination of the Executive's employment for Cause without notice and with immediate effect.

(b)

The Executive’s employment hereunder may be terminated by the Board due to the Executive’s Disability. For purposes of this Agreement, a termination for “Disability” shall occur (i) when the Board has provided a written termination notice to the Executive supported by a written statement from an Independent Physician (as defined below) to the effect that the Executive shall have become so physically or mentally incapacitated as to be unable to resume, even with reasonable accommodation as may be required under the Americans With Disabilities Act, within the ensuing twelve (12) months, the Executive’s employment hereunder by reason of physical or mental illness or injury, or (ii) upon rendering of a written termination notice by the Company after the Executive has been unable to substantially perform his duties hereunder, even with reasonable accommodation as may be required under the Americans With Disabilities Act, for one hundred twenty (120) or more consecutive days, or more than one hundred eighty (180) days in any consecutive twelve (12) month period, by reason of any physical or mental illness or injury. For purposes of this Section 8(b), the Executive agrees to make himself available and to cooperate in any reasonable examination by a reputable independent physician mutually selected by the Company and the Executive, or the Executive’s legal representatives in the event the Executive is unable to make such selection due to mental incapacity, and paid for by the Company (“Independent Physician”). Notwithstanding the foregoing, nothing herein shall give the Company the right to terminate the Executive prior to discharging its obligations to the Executive, if any, under the Family and Medical Leave Act, the Americans With Disabilities Act, or any other applicable law. The Company shall reimburse the Executive for the Executive’s actual cost of maintaining a supplementary long-term disability insurance policy during the Term up to a maximum reimbursement of $10,000 per year.

(c)

The Executive’s employment hereunder may be terminated by the Company (or its successor) by written notice to the Executive upon the occurrence of a Change of Control. For purposes of this Agreement, “Change of Control” means (i) the acquisition, directly or indirectly, following the Effective Date by any person (as such term is defined in Section 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended), in one transaction or a series of related transactions, of securities of the Company representing in excess of fifty percent (50%) of the combined voting power of the Company’s then outstanding securities if such person or his or its affiliate(s) do not own in excess of fifty percent (50%) of such voting power on the Effective Date of this Agreement, (ii) the future disposition by the Company (whether direct or indirect, by sale of assets or stock, merger, consolidation or otherwise) of all or substantially all of its business and/or assets in one transaction or series of related transactions other than a merger effected exclusively for the purpose of changing the domicile of the Company, or (iii) a “corporate transaction” as defined in the Company equity incentive plans under which the Executive has been granted Equity Awards. Notwithstanding the foregoing, if the Change of Control does not constitute a change in the ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), the amount of cash severance payable pursuant to Section 9(b), if any, shall be paid in equal installments in accordance with the Company’s then payroll practice over an 18-month period. Solely for purposes of Section 409A of the Code, each installment payment under this Agreement is considered a separate payment.

(d)

The Executive’s employment hereunder may be voluntarily terminated by the Executive for Good Reason. For purposes of this Agreement, “Good Reason” shall mean any of the following without the Executive’s written consent: (i) any material reduction by the Company of the Executive’s duties, or responsibilities or authority; (ii) any material reduction by the Company of the Executive’s Base Salary (it being understood that an across-the-board reduction (which reduction may not exceed 10%) applicable to all executive officers of the Company, including the Executive, shall not be deemed a reduction for purposes of this definition); (iii) any material reduction by the Company of the Executive’s target percentage applicable to the Annual Performance Bonus payable hereunder (iv) the Executive no longer reports to the Board of the Company or its successor; (v) any requirement by the Company that the Executive locate the Executive’s residence or primary place of employment to a location outside a 50-mile radius of such location mutually agreed upon between the Company and the Executive as of the Effective Date, or such other location that the Company and the Executive may mutually agree upon and designate from time to time during the Term; or (vi) a material breach by the Company of Sections 4 or 7(b) of this Agreement which is not cured by the Company within thirty (30) days after written notice thereof is given to the Company by the Executive. However, notwithstanding the above, Good Reason shall not exist unless: (x) the Executive notifies the Board within thirty (30) days of the initial existence of one of the adverse events described above, and (y) the Company fails to correct the adverse event within thirty (30) days of such notice, and (z) the Executive’s voluntary termination because of the existence of one or more of the adverse events described above occurs within ninety (90) days of the initial existence of the event.

(e)

The Executive’s employment may be terminated by the Company without Cause by delivery of written notice to the Executive effective the date of delivery of such notice. For the avoidance of doubt, termination of the Executive’s employment due to his death or Disability does not constitute a termination for Cause.

(f)

The Executive’s employment may be terminated by the Executive in the absence of Good Reason by delivery of written notice to the Company effective fifteen (15) days after the date of delivery of such notice.

Compensation upon Termination.

(a)

Accrued Benefits. Upon termination of the Executive’s employment by either party regardless of the cause or reason, the Executive shall be entitled to the following, referred to herein as the “Accrued Benefits”: (i) payment for any accrued, unpaid Base Salary through the termination date; (ii) if provided for under the Company’s vacation plan or policy or required by applicable law, payment for any accrued, unused vacation days through the termination date; and (iii) reimbursement for any approved business expenses that the Executive has timely submitted for reimbursement in accordance with the Company’s business expense reimbursement policy or practice. Except as otherwise expressly provided by this Agreement, the Company shall have no further payment obligations to the Executive and all Equity Awards that have not vested as of the termination date shall be forfeited to the Company as of such date. Subject to this Section 9, the vested portion of any stock options held by the Executive as of the Executive’s termination date shall remain exercisable for ninety (90) days following such termination.

(b)

Change of Control Separation Benefits. If the Executive’s employment is terminated due to death, by the Company due to Disability pursuant to Section 8(b), by the Company without Cause pursuant to Section 8(e) or by the Executive for Good Reason pursuant to Section 8(d) and such termination occurs during the period beginning one (1) month preceding the date of a Change of Control and ending twelve (12) months immediately following such Change of Control (the “COC Period”), provided that the Executive signs and does not revoke a general release of claims against the Company within the time period specified therein (which time period shall not exceed sixty (60) days), substantially in the form attached hereto as Exhibit A, with such changes as may be further necessitated by changes in applicable law (the “Release”), then the Company shall provide the following benefits to the Executive, referred to herein as the “Change of Control Separation Benefits”: (i) a lump sum payment equal to eighteen (18) months of the Executive’s then-current Base Salary; (ii) the full target Annual Performance Bonus for the year in which such termination occurs multiplied by 1.5, less any installments paid in advance (items (i) and (ii) being the “Change of Control Separation Pay”); (iii) immediate vesting in full of all Equity Awards (including Equity Awards that vested based on performance but only to the extent accelerated vesting is provided in the such Equity Awards); provided, however, that (A) in the event that a termination without Cause or termination for Good Reason or termination due to death or Disability occurs during the one (1) month immediately preceding a Change of Control (i.e., the first month of a COC Period), any Equity Awards outstanding as of the Executive’s termination shall not accelerate in connection with such termination but instead will remain outstanding and eligible to vest pursuant to this provision immediately prior to the consummation of such Change of Control (assuming the timely execution and non-revocation of the Release) and (B) in the event that termination without Cause or a termination for Good Reason or termination due to death or Disability occurs prior to a Change of Control and such Change of Control is not consummated on or prior to the one (1) month anniversary of such termination, no vesting shall occur pursuant to this Section 9(b) and any Equity Awards outstanding as of the Executive’s termination shall vest, if at all, and terminate in accordance with, and to the extent provided in, Section 9(c) of this Agreement; (iv) extension of the exercise period for all vested

stock options held by the Executive as of the termination date until the earlier of the first anniversary of the employment termination date and the termination date of the vested stock options; and (v) if the Executive properly and timely elects to continue his health insurance benefits under COBRA or applicable state continuation coverage after the termination date, reimbursement for the portion of Executive’s health continuation coverage premiums that the Company would have paid had the Executive remained employed by the Company until the earlier of (A) the eighteen (18) months following the month in which the Executive’s termination date occurs, or (B) the maximum period permitted by applicable law, provided that the Company’s obligation to pay a portion of the Executive’s health continuation coverage premiums will terminate if Executive becomes eligible for health insurance benefits from another employer during the reimbursement period. Subject to the Release being effective, the Change of Control Separation Pay will be paid within sixty (60) days after the termination date; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payments, to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall be paid no earlier than the first Company payroll date in the second calendar year and, in any case, by the last day of such 60-day period.

(c)

Base Separation Benefits. If the Executive’s employment is terminated during the Term and outside of the COC Period as a result of the Executive’s Disability pursuant to Section 8(b), by the Company without Cause pursuant to Section 7(e), or by the Executive for Good Reason pursuant to Section 7(d), provided that the Executive signs and does not revoke the Release within the time period specified therein (which time period shall not exceed sixty (60) days), then the Company shall provide the following benefits to the Executive, referred to herein as the “Base Separation Benefits”: (i) the continued payment in installments of the Executive’s then-current Base Salary for a period of twelve (12) months following the termination date (the “Base Separation Pay”); (ii) an Annual Performance Bonus, if any, for the year in which termination occurs in an amount equal to the amount Executive would have earned based on Company’s performance if Executive was employed for the full year, pro-rated based on the number of days employed for the year of termination; (iii) all Equity Awards which would have time vested during the twelve (12) months following the termination date shall accelerate and vest; (iv) extension of the exercise period for all vested stock options held by the Executive as of the termination date until the earlier of the first anniversary of the employment termination date and the termination date of the vested stock options; and (v) if the Executive properly and timely elects to continue Executive’s health insurance benefits under COBRA or applicable state continuation coverage after the termination date, reimbursement for the portion of the Executive’s health continuation coverage premiums that the Company would have paid had the Executive remained employed by the Company until the earlier of (A) the twelve (12) months following the month in which the Executive’s termination date occurs, or (B) the maximum period permitted by applicable law, provided that the Company’s obligation to pay a portion of the Executive’s health continuation coverage premiums will terminate if he becomes eligible for health insurance benefits from another employer during the reimbursement period. The first installment of the Base Separation Pay will be paid on the Company’s first regular payday occurring following the effectiveness of the Release in an amount equal to the sum of payments of Base Salary that would have been paid if Executive had remained in employment for the period from the termination date through the payment date. The remaining installments will be paid until the end of the 12-month period at the same rate as the Base Salary in accordance with the Company’s normal payroll practices for its employees. Notwithstanding the foregoing, if the 60-day period for the execution and non-revocation of the Release begins in one calendar year and ends in a second calendar year, the Base Separation Pay, to the extent it qualifies as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall begin to be paid no earlier than the first Company payroll date in the second calendar year and, in any case, by the last day of such 60-day period; provided, however, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following the termination date. The Executive understands that if the Executive is eligible to receive the Base Separation Benefits, such Base Separation Benefits shall be in lieu of and not in addition to the Change of Control Separation Benefits described in Section 9(b) of this Agreement. Notwithstanding the foregoing, if the Executive is entitled to receive the Base Separation Benefits but violates any provisions of this Agreement, the PIIA or any other agreement entered into by the Executive and the Company after termination of employment, the Company will be entitled to immediately stop paying any further installments of the Base Separation Benefits.

(d)

This Section 9 sets forth the only obligations of the Company with respect to the termination of the Executive’s employment with the Company, except as otherwise required by law, and the Executive acknowledges that, upon the termination of the Executive’s employment, the Executive shall not be entitled to any payments or benefits which are not explicitly provided in Section 9.

(e)

Upon termination of the Executive’s employment hereunder for any reason, the Executive shall be deemed to have resigned as director and officer of the Company and each subsidiary of the Company, to the extent applicable, effective as of the date of such termination, unless otherwise requested by the Board.

(f)

The provisions of this Section 9 shall survive any termination of this Agreement.

10.

Section 409A. The intent of the parties to this Agreement is that the payments, compensation and benefits under this Agreement be exempt from or comply with Section 409A of the Code and the regulations and guidance promulgated thereunder (collectively, “Section 409A”) and, in this connection, the following shall be applicable:

(a)

To the greatest extent possible, this Agreement shall be interpreted to be exempt from or in compliance with Section 409A.

(b)

If any severance, compensation, or benefit required by this Agreement is to be paid in a series of installment payments, each individual payment in the series shall be considered a separate payment for purposes of Section 409A.

(c)

If any severance, compensation, or benefit required by this Agreement that constitutes “nonqualified deferred compensation” within the meaning of Section 409A is considered to be paid on account of “separation from service” within the meaning of Section 409A, and the Executive is a “specified employee” within the meaning of Section 409A, no payments of any of such severance, compensation, or benefit shall be made until the earlier of six (6) months plus one (1) day after such separation from service or the Executive’s death (the “New Payment Date”). The aggregate amount of any such payments that would have otherwise been paid during the period between the date of separation from service and the New Payment Date shall be paid to the Executive or his estate in a lump sum payment on the New Payment Date. Thereafter, any severance, compensation, or benefit required by this Agreement that remains outstanding as of the day immediately following the New Payment Date shall be paid without delay over the time period originally scheduled, in accordance with the terms of this Agreement.

(d)

To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from

service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A 1(h).

(e)

The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

(f)

The provisions of this Section 10 shall survive any termination of this Agreement.

11.

Section 280G.

(a)

Notwithstanding any other provision of this Agreement or any other plan, arrangement or agreement to the contrary, if any of the payments or benefits provided or to be provided by the Company or its affiliates to the Executive or for the Executive’s benefit pursuant to the terms of this Agreement or otherwise (“Covered Payments”) constitute parachute payments (“Parachute Payments”) within the meaning of Section 280G of the Code and would, but for this Section 11 be subject to the excise tax imposed under Section 4999 of the Code (or any successor provision thereto) or any similar tax imposed by state or local law or any interest or penalties with respect to such taxes (collectively, the “Excise Tax”), then prior to making the Covered Payments, a calculation shall be made comparing (i) the Net Benefit (as defined below) to the Executive of the Covered Payments after payment of the Excise Tax to (ii) the Net Benefit to the Executive if the Covered Payments are limited to the extent necessary to avoid being subject to the Excise Tax. Only if the amount calculated under (i) above is less than the amount under (ii) above will the Covered Payments be reduced to the minimum extent necessary to ensure that no portion of the Covered Payments is subject to the Excise Tax (that amount, the “Reduced Amount”). “Net Benefit” shall mean the present value of the Covered Payments net of all federal, state, local, foreign income, employment and excise taxes.

(b)

Any such reduction shall be made in accordance with Section 409A of the Code and the following: (i) the Covered Payments which do not constitute nonqualified deferred compensation subject to Section 409A of the Code shall be reduced first; and (ii) all other Covered Payments shall then be reduced as follows: (A) cash payments shall be reduced before non-cash payments; and (B) payments to be made on a later payment date shall be reduced before payments to be made on an earlier payment date.

(c)

Any determination required under this Section 11 shall be made in writing in good faith by the accounting firm that was the Company’s independent auditor immediately before the Change of Control (the “Accounting Firm”). The Accounting Firm shall provide detailed supporting calculations to the Company and the Executive as requested by the Company or the Executive. The Company and the Executive shall provide the Accounting Firm with such information and documents as the Accounting Firm may reasonably request in order to make a determination under this Section 11. For purposes of making the calculations and determinations required by this Section 11, the Accounting Firm may rely on reasonable, good faith assumptions and approximations concerning the application of Section 280G and Section 4999 of the Code. The Accounting Firm’s determinations shall be final and binding on the Company and the

Executive. The Company shall be responsible for all fees and expenses incurred by the Accounting Firm in connection with the calculations required by this Section 11.

(d)

It is possible that after the determinations and selections made pursuant to this Section 11 the Executive will receive Covered Payments that are in the aggregate more than the amount provided under this Section 11 (“Overpayment”) or less than the amount provided under this Section 11 (“Underpayment”).

(i)

In the event that: (A) the Accounting Firm determines, based upon the assertion of a deficiency by the Internal Revenue Service against either the Company or the Executive which the Accounting Firm believes has a high probability of success, that an Overpayment has been made or (B) it is established pursuant to a final determination of a court or an Internal Revenue Service proceeding that has been finally and conclusively resolved that an Overpayment has been made, then the Executive shall pay any such Overpayment to the Company.

(ii)

In the event that: (A) the Accounting Firm, based upon controlling precedent or substantial authority, determine that an Underpayment has occurred or (B) a court of competent jurisdiction determines that an Underpayment has occurred, any such Underpayment will be paid promptly by the Company to or for the benefit of the Executive.

Release of Claims

In consideration for, among other terms, the Separation Benefits, to which you acknowledge you would otherwise not be entitled, you, on behalf of yourself and your heirs, executors, representatives, agents, insurers, administrators, successors and assigns (collectively, the “Releasors”) voluntarily release and forever discharge the Company, its affiliated and related entities, its and their respective predecessors, successors and assigns, its and their respective employee benefit plans and fiduciaries of such plans, and the current and former officers, directors, shareholders, employees, attorneys, insurers, accountants and agents of each of the foregoing in their official and personal capacities (collectively referred to as the “Releasees”) generally from all claims, demands, debts, damages and liabilities of every name and nature, known or unknown (“Claims”) that, as of the date when you sign this Agreement, you and the other Releasors have, ever had, now claim to have or ever claimed to have had against any or all of the Releasees. This release includes, without limitation, all Claims: relating to your employment by the Company and the termination of your employment; of wrongful discharge or violation of public policy; of breach of contract; of defamation or other torts; of retaliation or discrimination under federal, state or local law (including, without limitation, Claims of discrimination or retaliation under the Age Discrimination in Employment Act, the Americans with Disabilities Act, Title VII of the Civil Rights Act of 1964 and the California Fair Employment and Housing Act); under any other federal or state statute (including, without limitation, Claims under the Fair Labor Standards Act, the California Family Rights Act and the Family and Medical Leave Act); for wages, bonuses, incentive compensation, commissions, stock, stock options, vacation pay or any other compensation or benefits, either under the California Labor Code, or otherwise; and for damages or other remedies of any sort, including, without limitation, compensatory damages, punitive damages, injunctive relief and attorney’s fees; provided, however, that this release shall not affect your vested rights under the Company’s Section 401(k) plan or your rights under this Agreement, and shall not waive (i) any rights that cannot be waived as a matter of law, (ii) any claims for coverage under any D&O insurance policy and (iii) any

claims for indemnification under any arrangement or agreement between you and the Company. Furthermore, this release shall not affect your rights to claims under state workers' compensation or unemployment laws and your right to file an administrative charge or complaint with or participate in a charge by the Equal Employment Opportunity Commission (the "EEOC"), or any other local, state, or federal administrative body or government agency that is authorized to enforce or administer laws related to employment, against the Company (with the understanding that any such filing or participation does not give you the right to recover any monetary damages against the Company; your release of claims herein bars you from recovering such monetary relief from the Company).

You agree not to accept damages of any nature, other equitable or legal remedies for your own benefit or attorney's fees or costs from any of the Releasees with respect to any Claim released by this Agreement. As a material inducement to the Company to enter into this Agreement, you represent that you have not assigned any Claim to any third party.

In granting the release herein, you understand that this Agreement includes a release of all claims known or unknown. In giving this release, which includes claims which may be unknown to you at present, you acknowledge that you have read and understand Section 1542 of the California Civil Code which reads as follows: "A general release does not extend to claims which the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her would have materially affected his or her settlement with the debtor or released party." You hereby expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to the release of any unknown or unsuspected claims you may have against the Company.

Non-Disparagement

You agree not to make any disparaging statements concerning the Company, or any of its affiliates, or its or their current or former officers, directors, shareholders, employees or agents, or any of the Company’s or its respective affiliates’ products or services. These non-disparagement obligations shall not in any way affect your obligation to testify truthfully in any legal proceeding.

Confidentiality of Agreement-Related Information

You agree, to the fullest extent permitted by law, to keep all Agreement-Related Information completely confidential. "Agreement-Related Information" means the negotiations leading to this Agreement and the existence and terms of this Agreement. Notwithstanding the foregoing, you may disclose Agreement-Related Information to your spouse, your attorney and your financial advisors, and to them only provided that they first agree for the benefit of the Company to keep Agreement-Related Information confidential. Nothing in this Section 6 shall be construed to prevent you from disclosing Agreement-Related Information to the extent required by a lawfully issued subpoena or duly issued court order; provided that you provide the Company with advance written notice and a reasonable opportunity to contest such subpoena or court order.

(b)

Protected Disclosures and Other Protected Actions. Nothing contained in this Agreement or your PIIA limits your ability to file a charge or complaint with any federal, state or local governmental agency or commission (a “Government Agency”). In addition, nothing contained in this Agreement or PIIA limits your ability to communicate with any Government Agency or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including your ability to provide documents or other information, without notice to the Company, nor does anything contained in this Agreement apply to truthful testimony in litigation.

(d)

Enforceability. If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

(e)

Waiver. No waiver of any provision of this Agreement shall be effective unless made in writing and signed by the waiving party. The failure of a party to require the performance of any term or obligation of this Agreement, or the waiver by a party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

(f)

Jurisdiction. You and the Company hereby agree that the state and federal courts situated in California shall have the exclusive jurisdiction to consider any matters related to this Agreement, including without limitation any claim of a violation of this Agreement.
