Item 4.01  Change in Registrant's Certifying Accountant.

         The firm of KPMG LLP served the registrant, FNB Bancorp (the
"Company"), as principal accountants for the 2004 fiscal year. On April 8, 2005,
the Board of Directors of the Company approved the recommendation of the Audit
Committee of the Board of Directors to change the Company's certifying
accountant. On April 13, 2005, the Company notified KPMG LLP of their dismissal
and termination as independent public accountants for the Company, effective
April 13, 2005.

         The audit reports of KPMG LLP on the consolidated financial statements
of the Company and its subsidiary, First National Bank of Northern California,
as of and for the fiscal years ending December 31, 2004 and 2003 did not contain
any adverse opinion or disclaimer of opinion, nor were they qualified or
modified as to uncertainty, audit scope or accounting principles.

         In connection with the audits of the two most recent fiscal years ended
December 31, 2004, and subsequent interim period through April 13, 2005, there
were no disagreements between the Company and KPMG LLP on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure, which disagreements if not resolved to the satisfaction of
KPMG LLP, would have caused it to make reference to the subject matter of the
disagreement in connection with its reports.

         None of the reportable events described under Item 304(a)(1)(v) of
Regulation S-K occurred within the Company's two most recent fiscal years ending
December 31, 2004, and the subsequent period through April 13, 2005.

         A letter from KPMG LLP dated April 18, 2005, addressed to the
Securities and Exchange Commission, in compliance with Item 304(a)(3) of
Regulation S-K, is attached to this report as Exhibit 16.

         On April 19, 2005, the Company announced that it had engaged Moss Adams
LLP as the Company's principal accountants for the 2005 fiscal year, effective
as of April 13, 2005 per the Board of Directors approval of the Audit
Committee's recommendation in compliance with Item 304(a)(1)(iii). A copy of the
April 19, 2005 press release of the Company, reporting the engagement of Moss
Adams LLP, is attached to this report as Exhibit 99.26 and is incorporated here
by reference.

         During the fiscal years ending December 31, 2004 and 2003, and the
interim period between December 31, 2004 and April 13, 2005, the Company did not
consult with Moss Adams LLP regarding any of the matters or events set forth in
Item 304(a)(2)(i) and (ii) of Regulation S-K.
