2. Vesting

No portion of the shares of Common Stock that the Participant is entitled to receive will be issued until such portion has vested. The RSUs shall vest in accordance with the Vesting Schedule as provided above in this Agreement, provided in each case that the Participant is then, and since the Award Date has remained, in Continuous Service.

3. Issuance of Common Stock

(a) Each vested RSU entitles the Participant to receive one share of Common Stock.

(b) As soon as practicable after each applicable anniversary of the Vesting Commencement Date, the Participant’s name shall be entered as the stockholder of record on the books and records of the transfer agent for the Company with respect to the shares of Common Stock underlying the vested RSUs upon compliance to the satisfaction of the Committee with all requirements under applicable laws or regulations in connection with such issuance and with the requirements of this Agreement. The determination of the Committee as to such compliance shall be final and binding on the Participant.

(c) Until such time as shares of Common Stock have been issued to the Participant pursuant to Section 3(b) above, the Participant shall not have any rights as a holder of shares of Common Stock underlying the RSUs, including, but not limited to, voting rights, rights to receive dividends and other distributions with respect to Common Stock, and stockholder inspection rights.

4. Termination of Continuous Service

The Participant’s right in any RSUs that are not vested as of the date on which the Participant’s Continuous Service has ceased shall automatically terminate on such date, and such RSUs shall be canceled and shall be of no further force and effect. In the event of termination of

Continuous Service, the Company, as soon as practicable following the effective date of termination, shall issue shares of Common Stock to the Participant (or the Participant’s designated beneficiary or estate executor in the event of Participant’s death) with respect to any RSUs which, as of the effective date of termination of Continuous Service, have vested but for which shares of Common Stock had not yet been issued to the Participant.

5. Adjustments

If, from time to time during the term of this Agreement: (i) there is any stock dividend, distribution or dividend of cash or property, stock split, or other change in the character or amount of any of the outstanding securities of the Company; or (ii) there is any consolidation, merger or sale of all, or substantially all, of the assets of the Company; then in such event, any and all new, substituted or additional securities, cash or other property that Participant would receive, or to which the Participant would be entitled, by reason of the Participant’s ownership of any shares of Common Stock issuable pursuant to the RSUs then held by the Participant, shall be immediately subject to the provisions of Section 2 and be deemed subject to the RSUs for all purposes with the same force and effect as the shares of Common Stock presently subject to this Agreement.

Subject to the terms of any other written agreement between the Participant and the Company related to the Participant’s employment by or other association with the Company, the Committee may, if it so determines in the exercise of its sole discretion, also make provision for proportionately adjusting the number or class of securities covered by the RSUs, as well as the price to be paid therefor, in the event that the Company effects one or more Corporate Transactions or other increases or reductions of shares of its outstanding Common Stock.

6. Transferability

This Agreement is personal to the Participant, is non-assignable, and is not transferable in any manner, by operation of law, or otherwise, other than by will or the laws of descent and distribution. This Award is available, during the Participant’s lifetime, only to the Participant, and thereafter, only to the Participant’s designated beneficiary.

7. Tax Withholding

The Participant shall not later than the date as of which the Award becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Company for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. The Participant may elect to have the minimum tax withholding obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Common Stock to be issued, or (ii) authorizing the Company to deduct cash payments from the Participant’s regularly scheduled payroll distributions that would satisfy the minimum required tax withholding amount due.

8. Tax Consequences

The Company makes no representation or warranty as to the tax treatment to the Participant of the Participant’s receipt of the Award or vesting of RSUs or upon Participant’s sale or other disposition of the Common Stock issued pursuant to the RSUs. The Participant should rely on his or her own tax advisors for all such advice.

9. Miscellaneous

(a) Notice under this Agreement shall be given to the Company at its principal place of business, and shall be given to the Participant at the address set forth below, or in either case at such other address as one party may subsequently furnish to the other party in writing.

(b) This Agreement does not confer upon the Participant any rights with respect to continuation of employment by the Company or any of its Subsidiaries.

(c) The Committee may amend the terms of this Agreement, prospectively or retroactively, but no such amendment shall impair the Participant’s rights under this Agreement without the Participant’s consent.

(d) This Agreement shall be construed and enforced in accordance with the laws of California, without regard to the conflicts of laws principles thereof.

(e) This Agreement shall be binding upon and inure to the benefit of any successor or assign of the Company and any executor, administrator, trustee, guardian or other legal representative of the Participant.

(f) This Agreement may be executed in counterparts. This Agreement constitutes the entire agreement between the parties relative to the subject matter of this Agreement, and supersedes all communications, whether written or oral, relating to the subject matter of this Agreement.
