10. A new Section 12.11 is added to the Employment Agreement to read as follows:

“12.11 Compliance with Internal Revenue Code Section 409A.

12.11.1 This Agreement will be administered and interpreted to maximize the involuntary separation pay and short-term deferral exemptions from Section 409A of the Code, and Officer is not permitted, directly or indirectly, to designate the taxable year of any payment. Any right to a series of installment payments under this Agreement will be treated as a right to a series of separate payments. Any installment payment under this Agreement that is payable during the short-term deferral period (as defined in Treas. Reg. § 1.409A-1(b)(4)) will be treated as a short-term deferral and not aggregated with other awards, plans, or payments. Any other payment that does not meet the short-term deferral requirement will, to the maximum extent possible be deemed to satisfy the exception from Internal Revenue Code section 409A and Treas. Reg. § 1.409A-1(b)(9)(iii)(A) for involuntary separation pay and shall not be aggregated with any other payment. Designated payment dates provided for in this Agreement are deemed to incorporate the grace periods provided by Treas. Reg. § 1.409A-3(d).

12.11.2 Notwithstanding anything in this Agreement to the contrary, if the Board of Directors (or its delegate) determines in its discretion that any payment or benefit due under this Agreement constitutes “nonqualified deferred compensation” subject to Internal Revenue Code section 409A, and that as of the date of Officer’s separation from service” (as defined in

Treas. Reg. § 1.409A-1(h)) Officer is a “specified employee” (as defined in Treas. Reg. § 1.409A-1(i)), then no such payment will be made or benefit provided before the date that is six months after the date of separation from service. Any payment or benefit that is delayed pursuant to the foregoing sentence will be accumulated and paid or otherwise provided, without interest, on the first business day of the seventh month following Officer’s separation from service. For purposes of this Agreement, whether Officer is a “specified employee” will be determined in accordance with the written procedures adopted by the Board of Directors, which procedures are incorporated by reference herein.”

11. Except as amended by this Amendment, the Employment Agreement shall continue unmodified and in full force and effect.

12. This Amendment is effective as of the date hereof. This Amendment contains the entire understanding of the parties to it relating to the subject matter hereof and cannot be changed or terminated except in writing signed by both the Company and Officer. This Amendment has been made and entered into in the State of California and shall be construed in accordance with the laws of the State of California without regard to the conflict of laws principles thereof. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument. This Amendment and all obligations and benefits hereunder shall bind and inure to the benefit of Officer, the Company and its respective affiliates, and their respective successors and assigns. No amendment or waiver of any term of this Amendment shall be effective unless made in writing.

     IN WITNESS WHEREOF, each of the parties has signed this Amendment on the date opposite their signature below.
