Item 1.01  Entry into a Material Definitive Agreement.
           ------------------------------------------

           On November 5, 2004, First National Bank of Northern California (the
"Bank"), a national banking association wholly owned by the registrant, entered
into (and announced its signing of) an Acquisition Agreement with Sequoia
National Bank, a national banking association with offices in San Francisco,
California ("Sequoia") and Hemisphere National Bank, a national banking
association based in Miami, Florida ("Hemisphere"), pursuant to which the Bank
proposes to acquire all of the assets and San Francisco banking operations of
Sequoia and Hemisphere proposes to simultaneously acquire the remaining national
bank charter of Sequoia, including Sequoia's regulatory authority to establish
branch offices elsewhere in the State of California. These all-cash transactions
will be taxable to the Sequoia shareholders.

           A copy of the Acquisition Agreement, as signed by the Bank, Sequoia
and Hemisphere on November 5, 2004, is attached to this report as Exhibit 2.2
and is incorporated here by reference.

           On November 5, 2004, the registrant issued a Press Release, "First
National Bank to Acquire Business of Sequoia National Bank," to announce the
signing of the Acquisition Agreement. A copy of the Press Release is attached to
this report as Exhibit 2.3 and is incorporated here by reference.

           The Acquisition Agreement has been approved by the respective Boards
of Directors of the Bank, Sequoia and Hemisphere. Consummation of the
transactions contemplated by the Acquisition Agreement is presently expected to
occur during the first quarter of 2005, subject to the satisfaction of various
conditions set forth in the Acquisition Agreement, including approval of the
Sequoia shareholders, the receipt of all necessary bank regulatory approvals and
other conditions customary for transactions of this type.

           Also on November 5, 2004, in accordance with the provisions of the
Acquisition Agreement, the Bank entered into a Director-Shareholder Agreement
with Peter T. Paul, Chairman and Chief Executive Officer of Sequoia, and with a
majority of the other members of the Sequoia Board of Directors, pursuant to
which Mr. Paul and such Directors have agreed to vote all of their shares of
Sequoia Common Stock in favor of, and to approve, the transactions described in
the Acquisition Agreement, and to recommend similar approval by the other
Sequoia shareholders, at a special meeting of Sequoia shareholders to be called
and held for the purpose of considering such transactions. Mr. Paul currently
owns approximately 62 percent of the outstanding Common Stock of Sequoia.

           A copy of the Director-Shareholder Agreement signed between the Bank
and each of Peter T. Paul, Tamara Blake, Kristen R. Decker, Paul Casellini,
Gilbert J. MacQuarrie and Leonard B. Auerbach is attached to this report as
Exhibit 2.4 and is incorporated here by reference.
