   Yes

   √

   No

   If answer is no, identify report(s).

    

3. Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

   Yes

   √

   No

   If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

   At present, the Company's best reasonable estimate is that it will report an after-tax net loss of approximately $4.4 million for the year ended December 31, 2010 as compared to an after-tax net loss of $4.5 million for the year ended December 31, 2009. The after-tax net loss of approximately $4.4 million for the year ended December 31, 2010 compares to after-tax net income of $1.4 million for the nine months ended September 30, 2010, and the previously released after-tax net loss of $2.9 million for the year ended December 31, 2010 announced in our press release of March 3, 2011. The difference in the December 31, 2010 results previously released in our press release of March 3, 2011 and the estimated net loss of $4.1 million for 2010 includes additional pre-tax provisions for loan losses of approximately $2.6 million. The largest factor contributing to the increased provision was the protracted nature of the economic downturn and its impact on real estate values in California. Assuming no further adjustments, at December 31, 2010 the Company's subsidiary United Security Bank had a total risk-based capital ratio of 15.58%, a Tier 1 capital ratio of 14.35% and a leverage ratio of 11.04%. The Bank's capital is above well-capitalized levels. The Company itself had a total risk-based capital ratio of 16.17%, a Tier 1 capital ratio of 14.90% and a leverage ratio of 11.05% as of December 31, 2010.
