As previously reported, 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 and merge with the remaining Sequoia national bank charter.

C. Privee is the registered bank holding company for HNB, and in order to obtain all approvals of the Office of the Comptroller of the Currency (the "OCC") required under terms of the Agreement, the parties hereto agree that Privee should be the purchaser of the "Consolidated Bank Stock" (as defined in the Agreement).

NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein and in the Agreement, the parties hereto agree as follows:
