All periods of notice shall be measured from the date of delivery thereof.

(c)Entire Agreement; Amendment. The recitals hereto are hereby incorporated herein by this reference. This Agreement, together with the exhibits hereto, constitute the entire agreement between the parties hereto with regard to the subject matter hereof and thereof, superseding all prior understandings and agreements, whether written or oral, including, without limitation, the Severance Agreement; provided, however, that any indemnification agreement and any outstanding vested equity award agreements (including, without limitation, any outstanding vested option agreement, restricted stock unit agreement, performance stock unit agreement, market stock unit agreement or other equity instrument by and between the Company and the Executive), and the Restrictive Covenants shall remain in full force and effect in accordance with the terms and conditions herein and therein.

may not be changed orally, but only by an agreement in writing signed by the party against whom enforcement of any such change is sought.

(d)409A Compliance. Notwithstanding any other provision herein to the contrary, the Company shall make the payments required hereunder in compliance with the requirements of Section 409A and any interpretative guidance issued thereunder. The Company may, in its sole and absolute discretion, delay payments hereunder or make such other modifications with respect to the timing of payments as it deems necessary to comply with Section 409A. Notwithstanding any provision herein to the contrary, in the event any payment or benefit hereunder is determined to constitute non-qualified deferred compensation subject to Section 409A, then to the extent necessary to comply with Section 409A, such payment or benefits shall not be made, provided or commenced until six (6) months after the Executive’s “separation from service” as such phrase is defined for the purposes of Section 409A.

(f)Effect of Headings. The titles of section headings herein contained have been provided solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this Agreement.

(g)Severability. The provisions of this Agreement are severable, and the invalidity of any provision shall not affect the validity of any other provision. In the event that any court of competent jurisdiction shall determine that any provision of this Agreement or the application thereof is unenforceable because of the duration or scope thereof, the parties hereto agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to the full extent permitted by law.

(h)Governing Law/Jurisdiction. This Agreement shall be binding upon the Executive and shall inure to the benefit of the Company and its successors and interest and assigns, and shall be construed in accordance with and governed by the laws of the State of California without regard to conflicts of laws. The parties hereto intend and hereby confer jurisdiction to enforce the covenants contained herein upon the state and federal courts sitting in the State of California. In the event that such courts shall hold any such covenant wholly unenforceable by reason of the breadth of scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the Company’s right to the relief

provided above in the courts of any other states within the geographical scope of such other covenants having appropriate personal and subject matter jurisdiction over the parties, as to breaches of such covenants in such other respective jurisdictions, the above covenants as they relate to each state being, for this purpose, severable into diverse and independent covenants.
