Item 5.02 Election of Directors.

As previously announced by the Registrant, Mr. Michael R. Wyman, Chairman of the Board of Directors of FNB Bancorp and First National Bank of Northern California, has resigned, effective as of December 31, 2009. On December 18, 2009, the Registrant announced that Ms. Lisa Angelot, a Director since 1999, has been appointed to serve as Chairwoman of the Board of Directors of FNB Bancorp and First National Bank of Northern California, effective upon the resignation of Mr. Wyman. Ms. Angelot will continue as a member of the committees of the Board of Directors on which she currently serves.

          On December 18, 2009, the Registrant announced that Dr. Thomas G. Atwood has been appointed Director of the FNB Bancorp and First National Bank of Northern California, effective as of January 1, 2010. Dr. Atwood previously served as a Director of First National Bank of Northern California for 19 years, starting in 1977. The committees of the Board of Directors on which Dr. Atwood is expected to serve are not known at this date.

          Dr. Atwood currently holds 479,500 shares or approximately 15% of FNB Bancorp stock, which includes 285,360 shares owned by Cypress Abbey Company, a corporation in which Dr. Atwood is the principal shareholder. Through its banking subsidiary, First National Bank of Northern California, the Registrant has and expects in the future to have banking transactions, including loans and other extensions of credit in the ordinary course of its business, with Dr. Atwood and Cypress Abbey Company, on substantially the same terms (including interest rates and collateral) as those prevailing for comparable transactions with others. The Bank’s existing loans to Dr. Atwood and Cypress Abbey Company do not involve more than the normal risk of collectability or present other unfavorable features.

          A copy of the News Release issued by the registrant on December 21, 2009 is attached as Exhibit 99.83

          Item 9.01 Financial Statements and Exhibits.
