If the Participant’s Service terminates for any reason, all Units subject to the Award which have not become Vested Units as of the time of such termination of Service (“Unvested Units”) shall be forfeited to the Company and all rights of Participant to such Unvested Units shall immediately terminate. Notwithstanding the foregoing, if a Participant’s Change in Control Severance Agreement or other similar agreement or employment agreement with the Company provide for additional service credit in the event of a termination of Service, such Participant shall receive additional service credit, provided that it shall not affect the determination of whether Units have been earned pursuant to performance metrics in the Grant Notice.

Corporate Transaction.

Effect of Corporate Transaction on Award. In the event of a Corporate Transaction, (i) the number of Earned Units for each Performance Period that has ended prior to the closing of the Corporate Transaction (the “Closing Date”) in accordance with the schedule for such Performance Period set forth in the Grant Notice (a “Completed Performance Period”) shall, if not previously certified by the Committee in accordance with Section 3 and settled in accordance with Section 5, be determined and certified by the Committee in accordance with Section 3 and settled in accordance with Section 5 within 30 days following the Closing Date in accordance with Section 5, but in any event no later than the 15th day of the third calendar month following the end of the calendar year in which the Closing Date occurs (the “Completed Performance Period Units”); and (ii) the 1-Year Performance Period and the 2-Year Performance Period, to the extent not Completed Performance Periods and subject to Section 9.1(a), shall be disregarded and the remaining Earned Units (if any) and the vesting thereof shall be determined based on an adjusted performance period that ends on the day immediately preceding the Closing Date (the “Adjusted Performance Period”) as follows:

Earned Units. The number of Earned Units for the Adjusted Performance Period shall be determined, taking into account the following:

The number of Adjusted Performance Period Earned Units, if any (not to exceed the Maximum Number of Units when combined with Completed Performance Period Earned Units), shall equal the excess, if any, of (a) the product of (i) the Target Number of Units and (ii) the Performance Multiplier determined for the Adjusted Performance Period, over (b) the Completed Performance Period Earned Units.

The Company Total Stockholder Return shall be determined as provided by Section 2.1, except that the Average Per Share Closing Price for the 30 market trading days ending on the last market trading day of the Adjusted Performance Period shall be replaced with the price per Share of Common Stock to be paid to the holder thereof in accordance with the definitive agreement governing the transaction constituting the Corporate Transaction (or, in the absence of such agreement, the closing price per Share of Common Stock on the last trading day of the Adjusted Performance Period as reported on the securities exchange constituting the primary market for the Common Stock).

The Benchmark Index Total Return shall be determined as provided by Section 2.3, except that for the purposes of clause (a) thereof, the Average Closing Index Value shall be determined for the 30 market trading days ending on the last market trading day of the Adjusted Performance Period.

Vested Units. As of the last day of the Adjusted Performance Period and provided that the Participant’s Service has not terminated prior to such date, a portion of the Earned Units determined in accordance with Section 9.1(a) shall become Vested Units (the “Accelerated Units”), with such portion determined by multiplying the total number of Earned Units by a fraction, the numerator of which equals the number of days contained in the Adjusted Performance Period and the denominator of which equals the number of days contained in the corresponding original Performance Period determined without regard to this Section, less the number of Completed Performance Period Units. The Accelerated Units shall be settled in accordance Section 5 within 30 days following the Closing Date but in any event no later than the 15th day of the third calendar month following the end of the calendar year in which the Closing Date occurs.

Unvested Units. Except as otherwise provided by Section 9.1(b), that portion of the Earned Units determined in accordance with Section 9.1(a) in excess of the number of Accelerated Units (such excess portion, a “Time-Vesting Unit Award”) shall become Vested Units in equal installments on the remaining original Vesting Date(s), provided that the Participant’s Service has not terminated prior to the applicable Vesting Date. The Units subject to the Time-Vesting Unit Award which become Vested Units shall be settled on the applicable Settlement Date in accordance with Section 5, provided that payment for each Vested Unit shall be made in the amount and in the form of the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a Share of Common Stock on the effective date of the Corporate Transaction was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares of Common Stock). For the purposes of this Section 9.1(c), the Settlement Date shall occur upon or as soon as practicable following the applicable Vesting Date, but in any event no later than the 15th day of the third calendar month following the end of the calendar year in which the Vesting Date occurs.

Vested Units in Corporate Transaction in which Awards are not Assumed. Notwithstanding anything to the contrary in Section 9.1(c) above or in the Plan, in the event of a Corporate Transaction in which the Units are not assumed or replaced by the successor entity, all of the Earned Units (as determined in accordance with Section 9.1(a) above) shall become Vested Units as of the last day of the Adjusted Performance Period and shall be settled in accordance Section 5 within 30 days following the Closing Date but in any event no later than the 15th day of the third calendar month following the end of the calendar year in which the Closing Date occurs.

Qualifying Termination in Connection with Corporate Transaction. Notwithstanding anything to the contrary in Section 9.1, in the event of a Corporate Transaction, if a Participant’s Change in Control Severance Agreement or other similar agreement or employment agreement with the Company provide for additional service credit or accelerated vesting in the event of a qualifying termination of Service in connection with a Corporate Transaction, this Award Agreement shall be read in conjunction therewith, provided, however, that provisions of this Award Agreement shall govern except to the extent that such Participant would receive greater benefits under the Change in Control Severance Agreement or other similar agreement or employment agreement with the Company.

Section 280G Provision.

Best After-Tax Result. In the event that any payment or benefit received or to be received by Participant pursuant to this Award Agreement or otherwise (“Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this subsection (a), be subject to the excise tax imposed by Section 4999 of the Code, any successor provisions, or any comparable federal, state, local or foreign excise tax (“Excise Tax”), then, subject to the provisions of Section 10.1 hereof, such Payments shall be either (A) provided in full pursuant to the terms of this Award Agreement or any other applicable agreement, or (B) provided as to such lesser extent which would result in no portion of such Payments being subject to the Excise Tax (“Reduced Amount”), whichever of the foregoing amounts, taking into account the applicable federal, state, local and foreign income, employment and other taxes and the Excise Tax (including, without limitation, any interest or penalties on such taxes), results in the receipt by Participant, on an after-tax basis, of the greatest amount of payments and benefits provided for hereunder or otherwise, notwithstanding that all or some portion of such Payments may be subject to the Excise Tax. Unless the Company and Participant otherwise agree in writing, any determination required under this Section shall be made by independent tax counsel designated by the Company and reasonably acceptable to Participant (“Independent Tax Counsel”), whose determination shall be conclusive and binding upon Participant and the Company for all purposes. For purposes of making the calculations required under this Section, Independent Tax Counsel may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code; provided that Independent Tax Counsel shall assume that Participant pays all taxes at the highest marginal rate. The Company and Participant shall furnish to Independent Tax Counsel such information and documents as Independent Tax Counsel may reasonably request in order to make a determination under this Section. The Company shall bear all costs that Independent Tax Counsel may reasonably incur in connection with any calculations contemplated by this Section. In the event that Section 10.1(i) (B) above applies, then any reduction in payments and/or benefits required by this Section 6 shall occur in the following order: (1) reduction of cash payments; (2) reduction of acceleration of vesting of equity awards; and (3) reduction of other benefits paid to Participant. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant for Participant’s Equity Awards. If the Internal Revenue Service (the “IRS”) determines that any Payment is subject to the Excise Tax, then Section 10.2 hereof shall apply, and the enforcement of Section10.2 shall be the exclusive remedy to the Company.

Adjustments. If, notwithstanding any reduction described in Section 10.1 hereof (or in the absence of any such reduction), the IRS determines that Participant is liable for the Excise Tax as a result of the receipt of one or more Payments, then Participant shall be obligated to surrender or pay back to the Company, within 120 days after a final IRS determination, an amount of such payments or benefits equal to the “Repayment Amount.” The Repayment Amount with respect to such Payments shall be the smallest such amount, if any, as shall be required to be surrendered or paid to the Company so that Participant’s net proceeds with respect to such Payments (after taking into account the payment of the Excise Tax imposed on such Payments) shall be maximized. Notwithstanding the foregoing, the Repayment Amount with respect to such Payments shall be zero if a Repayment Amount of more than zero would not eliminate the Excise Tax imposed on such Payments or if a Repayment Amount of more than zero would not maximize the net amount received by Participant from the Payments. If the Excise Tax is not eliminated pursuant to this Section 10.2, Participant shall pay the Excise Tax.

Compliance with Section 409A.

Withholding Taxes and Stock Withholding.

In General. Regardless of any action the Company or Participant’s actual employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), Participant acknowledges that the ultimate liability for all Tax-Related Items legally due by Participant is and remains Participant’s responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the award, including the settlement of the Units, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends; and (2) do not commit to structure the terms of the award or any aspect of the Units to reduce or eliminate Participant’s liability for Tax-Related Items.

Withholding. Prior to the settlement of Participant’s Units, Participant shall pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all withholding and payment on account obligations of the Company and/or the Employer. In this regard, Participant authorizes the Company and/or the Employer to withhold all applicable Tax-Related Items legally payable by Participant from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer. With the Committee’s consent, these arrangements may also include, if permissible under local law, (a) withholding Shares that otherwise would be issued to Participant when Participant’s Units are settled, provided that the Company only withholds the amount of Shares necessary to satisfy the minimum statutory withholding amount, (b) having the Company withhold taxes from the proceeds of the sale of the Shares, either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization), or (c) any other arrangement approved by the Company. The Fair Market Value of these Shares, determined as of the effective date when taxes otherwise would have been withheld in cash, will be applied as a credit against the withholding taxes. Finally, Participant shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of Participant’s participation in the Plan or Participant’s purchase of Shares that cannot be satisfied by the means previously described. The Company may refuse to deliver the Shares if Participant fails to comply with Participant’s obligations in connection with the Tax-Related Items as described in this section.

Entire Agreement; Enforcement of Rights. This Award Agreement, the Plan and the Grant Notice constitute the entire agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning the purchase of the Shares hereunder are superseded. No modification of or amendment to this Award Agreement, nor any waiver of any rights under this Award Agreement, shall be effective unless in writing and signed by the parties to this Award Agreement.

Compliance with Laws and Regulations. The issuance of Shares will be subject to and conditioned upon compliance by the Company and Participant with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed or quoted at the time of such issuance or transfer.

Governing Law; Severability. If one or more provisions of this Award Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Award Agreement, (ii) the balance of this Award Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Award Agreement shall be enforceable in accordance with its terms. This Award Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law.

No Rights as Employee, Director or Consultant. Nothing in this Award Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent or Subsidiary of the Company, to terminate Participant^’s Service, for any reason, with or without cause.
