**10. TRANSFERABILITY.** Your option is not transferable, except by will or bythe laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in theevent of your death, shall thereafter be entitled to exercise your option. In addition, if permitted by the Company you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 ofthe Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into a transfer and other agreements required by the Company. 

**11. CHANGE IN CONTROL.**If a Change in Control occurs and as of, or within thirteen(13) months after, the effective time of such Change in Control your Continuous Service terminates due to an involuntary termination (not including death or Disability) without Cause, then, as of the date of termination of Continuous Service,the vesting and exercisability of your option shall be accelerated in full. 

**12. PARACHUTE PAYMENTS.**If any payment or benefit you would receive pursuant to a Change in Control from the Company or otherwise (“***Payment***”) would (i) constitute a “parachute payment” within the meaning of Section 280G ofthe Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “***Excise Tax***”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount”shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after takinginto account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Paymentnotwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shalloccur in the following order unless you elect in writing a different order (*provided, however,* that such election shall be subject to Company approval if made on or after the effective date of the event that triggers the Payment): reductionof cash payments; cancellation of accelerated vesting of Stock Awards; reduction of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in thereverse order of the date of grant of your Stock Awards (*i.e.*, earliest granted Stock Award cancelled last) unless you elect in writing a different order for cancellation. 

The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shallperform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognizedaccounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. 

The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supportingdocumentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by you or the Company) or such other time as requested by you or the Company. If theaccounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish you and the Company with an opinion reasonably acceptable to you that no Excise Taxwill be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company. 

**13. RIGHTOF FIRST REFUSAL.** Shares of Common Stock that you acquire uponexercise of your option are subject to any right of first refusal that may be described in the Company’s bylaws in effect at such time the Company elects to exercise its right; *provided, however,* that if your option is an Incentive StockOption and the right of first refusal described in the Company’s bylaws in effect at the time the Company elects to exercise its right is more beneficial to you than the right of first refusal described in the Company’s bylaws on the Dateof Grant, then the right of first refusal described in the Company’s bylaws on the Date of Grant shall apply.

**14. RIGHTOF REPURCHASE.** To the extentprovided in the Company’s bylaws in effect at such time the Company elects to exercise its right, the Company shall have the right to repurchase all or any part of the shares of Common Stock you acquire pursuant to the exercise of your option.

**15. OPTIONNOTA SERVICE CONTRACT.** Your option is notan employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue youremployment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant forthe Company or an Affiliate. 

**16. WITHHOLDING OBLIGATIONS.**

**(a)**At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you herebyauthorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated bythe Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise ofyour option. 

**(b)**Upon your request and subject to approval by the Company, in its sole discretion, and compliance with anyapplicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determinedby the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option as a liability for financial accounting purposes).If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timelyelection under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the determination of such taxwithholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your optionthat are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

**(c)**You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from anyescrow provided for herein unless such obligations are satisfied. 

**17. TAXCONSEQUENCES**. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claimagainst the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of theCode only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associatedwith the option. Because the Common Stock is not traded on an established securities market, the Fair Market Value is determined by the Board, perhaps in consultation with an independent valuation firm retained by the Company. You acknowledge thatthere is no guarantee that the Internal Revenue Service will agree with the valuation as determined by the Board, and you shall not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that theInternal Revenue Service asserts that the valuation determined by the Board is less than the “fair market value” as subsequently determined by the Internal Revenue Service. 

**18. NOTICES.** Any notices provided for in your option or the Plan shall be given in writing and shall be deemedeffectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 

**19. GOVERNING PLAN DOCUMENT.** Your option is subject to all the provisions of the Plan, theprovisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflictbetween the provisions of your option and those of the Plan, the provisions of the Plan shall control.
