14. **Amendments**. The 2007 Plan and RSUs may be amended or altered by the Administrator to the extentprovided in the 2007 Plan. 

****15.**Other Matters.**

(a) Any prior agreements, commitments or negotiations concerning the RSUs are superseded by these Standard Terms and your Notice of Grant. You hereby acknowledge that a copy of the 2007 Plan has been madeavailable to you. The grant of RSUs to you in any one year, or at any time, does not obligate the Company or any Subsidiary to make a grant in any future year or in any given amount and should not create an expectation that the Company or anySubsidiary might make a grant in any future year or in any given amount. RSUs are not part of your employment contract (if any) with the Company (unless otherwise provided therein), your salary, your normal or expected compensation, or otherremuneration for any purposes, including for purposes of computing severance pay or other termination compensation or indemnity. 

(b) RSUs are not part of your Service contract (if any, unless otherwise specified therein), your salary, your normal or expected compensation, or other remuneration for any purposes, including for purposes of computing severance pay orother termination compensation or indemnity. 

(c) Notwithstanding any other provision of these Standard Terms, if any changesin the financial or tax accounting rules applicable to the RSUs covered by these Standard Terms shall occur which, in the sole judgment of the Administrator, may have an adverse effect on the reported earnings, assets or liabilities of the Company,the Administrator may, in its sole discretion, modify these Standard Terms or cancel and cause a forfeiture with respect to any unvested RSUs at the time of such determination. 

(d) Nothing contained in these Standard Terms creates or implies an employment contract or term of employment upon which you may rely.

(e) Notwithstanding any provision of these Standard Terms, the Notice of Grant or the 2007 Plan to the contrary, if, at thetime of your termination of Service with the Company, you are a “specified employee” as defined in Section 409A of the Code, and one or more of the payments or benefits received or to be received by you pursuant to the RSUs wouldconstitute deferred compensation subject to Section 409A, no such payment or benefit will be provided under the RSUs until the earliest of (A) the date which is six (6) months after your “separation from service” for anyreason, other than death or “disability” (as such terms are used in Section 409A(a)(2) of the Code), (B) the date of your death or “disability” (as such term is used in Section 409A(a)(2)(C) of the Code) or(C) the effective date of a “change in the ownership or effective control” of the Company (as such term is used in Section 409A(a)(2)(A)(v) of the Code). The provisions of this Section 15(e) shall only apply to theextent required to avoid your incurrence of any penalty tax or interest under Section 409A of the Code or any regulations or Treasury guidance promulgated thereunder. In addition, if any provision of the RSUs would cause you to incur anypenalty tax or interest under Section 409A of the Code or any regulations or Treasury guidance promulgated thereunder, the Administrator may reform such provision to maintain to the maximum extent practicable the original intent of theapplicable provision without violating the provisions of Section 409A of the Code. 

 

6 

(f) Notwithstanding any provision of these Standard Terms, the Notice of Grant or the 2007Plan to the contrary, if the Company determines, based upon the advice of the tax advisors for the Company, that part or all of the consideration, compensation or benefits to be paid to you pursuant to the RSUs constitute “parachutepayments” under Section 280G(b)(2) of the Code, then, if the aggregate present value of such parachute payments, singularly or together with the aggregate present value of any consideration, compensation or benefits to be paid to you underany other plan, arrangement or agreement which constitute “parachute payments” (collectively, the “***Parachute Amount***”) exceeds 2.99 times your “base amount,” as defined in Section 280G(b)(3) of theCode (the “***Base Amount***”), the amounts constituting “parachute payments” which would otherwise be payable to you or for your benefit shall be reduced to the extent necessary so that the Parachute Amount is equal to2.99 times the Base Amount (the “***Reduced Amount***”); *provided*, *however*, that the Company shall pay to you the Parachute Amount without reduction if the Company determines that payment of the Parachute Amount wouldgenerate more after-tax income to you than the Reduced Amount. In the event of a reduction of the payments that would otherwise be paid to you, then the Company may elect which and how much of any particular entitlement shall be eliminated orreduced and shall notify you promptly of such election; *provided*, *however*, that the aggregate reduction shall be no more than as set forth in the preceding sentence of this Section 15(f). Within ten (10) days followingsuch election, the Company shall pay you such amounts as are then due pursuant to the RSUs and shall pay you in the future such amounts as become due pursuant to the RSUs. As a result of the uncertainty in the application of Section 280G of theCode at the time of a determination hereunder, it is possible that payments will be made by the Company which should not have been made (“***Overpayment***”) or that additional payments which are not made by the Company pursuant tothis Section 15(f) should have been made (“***Underpayment***”). In the event of a final determination by the Internal Revenue Service, a final determination by a court of competent jurisdiction or a change in theprovisions of the Code or regulations or tax law, that an Overpayment has been made, any such Overpayment shall be treated for all purposes as a loan to you that you shall repay to the Company together with interest at the applicable federal rateprovided for in Section 7872(f)(2) of the Code. In the event of a final determination by the Internal Revenue Service, a final determination by a court of competent jurisdiction or a change in the provisions of the Code or regulations or taxlaw pursuant to which an Underpayment arises under this Agreement, any such Underpayment shall be promptly paid by the Company to you or for your benefit, together with interest at the applicable federal rate provided for in Section 7872(f)(2)of the Code. 

(g) Because these Standard Terms relate to terms and conditions under which you may be issued shares of CommonStock, an essential term of these Standard Terms is that it shall be governed by the laws of the State of Delaware, without regard to choice of law principles of Delaware or other jurisdictions. Any action, suit, or proceeding relating to theseStandard Terms or the RSUs granted hereunder shall be brought in the state or federal courts of competent jurisdiction in the State of California. 

(h) Copies of the Company’s Annual Report to Stockholders for its latest fiscal year and the Company’s latest quarterly report are available, without charge, at the Company’s businessoffice.
