Item 5.02 (d) Election of Director.

         On March 28, 2007, the registrant announced that Ms. Merrie Turner
Lightner has been appointed a Director of FNB Bancorp and and its subsidiary,
First National Bank of Northern California, effective April 1, 2007. Ms.
Lightner will also serve as a member of the Loan and Discount Committee of the
Board of Directors.

         Ms. Lightner and her company, Lightner Property Group, Inc., currently
have (and expect to have in the future) banking transactions, including loans
and other extensions of credit, in the ordinary course of business with First
National Bank of Northern California. Such loans were made on substantially the
same terms, including interest rate and collateral, as those prevailing at the
time for comparable loans with persons not related to the Bank, and such loans
do not involve more than the normal risk of collectibility or present other
unfavorable features.

         A copy of the News Release issued by the registrant on March 28, 2007
is attached as Exhibit 99.47 and is incorporated here by reference.
