The undersigned is currently the beneficial owner (or holder of record) of shares of common and/or preferred stock of AMERICA CALIFORNIA BANK (“ACB”), a California banking corporation located at 417 Montgomery Street, San Francisco, CA 94104 U.S.A. (“ACB”), in the amount indicated on the signature page below (the “Shares”);

ACB proposes to sign an Agreement and Plan of Reorganization and Merger with FNB Bancorp and its wholly-owned subsidiary, First National Bank of Northern California (together, “FNB”), pursuant to which ACB would become a wholly-owned subsidiary of FNB and all outstanding shares of ACB common stock and preferred stock would be converted into the right to receive the cash consideration described in the proposed Agreement equal to $10.60 per share, for a total of approximately $21,510,000; and

NOW, THEREFORE, I confirm as follows:

1.          Upon my receipt of the special meeting materials to be prepared by the Board of Directors for distribution to all ACB shareholders, my intention is to vote all of my Shares (or to use all reasonable efforts to cause my Shares to be voted) in favor of the proposed Agreement with FNB, and in favor of the mergers and other transactions contemplated by the proposed Agreement with FNB, as will be recommended by the Board of Directors.

2.          Without first giving written notice to the Board of Directors, my intention is to not, directly or indirectly sell, transfer, assign or otherwise dispose of any of my Shares prior to the conclusion of the special meeting of ACB shareholders.

3.          Unless recommended by the Board of Directors and advised to me in writing, I will not directly or indirectly solicit any proposals from any person relating to the disposition of the business or assets of ACB, the acquisition of ACB common or preferred stock or any business combination between ACB and any person, group or entity, except for FNB.
