The FIRST NATIONAL BANK OF NORTHERN CALIFORNIA ("Company") and JAMES B. RAMSEY ("Executive") originally entered into the FIRST NATIONAL BANK OF NORTHERN CALIFORNIA Salary Continuation Agreement ("Agreement") on December 31, 1999, which was subsequently amended and restated on December 14, 2001, and September 14, 2004.

The Company shall pay the annual benefit to the Executive in twelve (12) equal monthly installments commencing on January 1, 2007. Such installment payments to the Executive shall continue for a period of twenty (20) years. This benefit shall be paid in lieu of any other benefit under this Agreement. In addition, the Company, in its sole discretion, may increase the annual benefit under this Section 2.1, provided any such increase shall be reflected on a new Schedule A.

9. Section 2.6 shall be added to the Agreement and shall read as follows:

Notwithstanding anything to the contrary in this Agreement, to the extent that any benefit under this Agreement is intended by the parties hereto to provide for a benefit distribution upon "Termination of Employment," "Termination of Service," or other similar severance from employment event (as contemplated in Section 409A(a)(2)(A)(i)), such distribution shall not be deemed a permissible distribution and will not be made to the Executive unless and until such event complies in all respects with the applicable rules and regulations set forth under
Section 409A of the Code regarding a "Separation from Service" distribution.
