Part II - Rules 12b-25(b) and (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed.(Check box if appropriate.)

Part III - Narrative

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Although management of United Security Bancshares (the “Company”), has been working diligently to complete all the required information for its Form 10-Q for the quarter ended September 30, 2011, and a substantial part of such information has been completed as of this date, the Company and its auditors require additional time to complete the preparation of the Company’s financial statements for the quarter ended September 30, 2010 and other related disclosures in the Form 10-Q. The Company’s ability to complete its Form 10Q for the quarter ended September 30, 2011 has been further impeded by the recent and unexpected illness of the Company’s Chief Financial Officer.

The Form 10-Q will be filed as soon as possible (and no later than the fifth calendar day following the prescribed due date).

   Ken L. Donahue	559	248-0468
   (Name)	(Area Code)	(Telephone Number)

2. Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed?

   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 $4.8 million for the quarter ended September 30, 2011 and an after-tax net loss of approximately $7.5 million for the nine months ended September 30, 3011, as compared to an after-tax net income of $411,000 for the quarter ended September 30, 2010 and an after-tax net income of $1.4 million for the nine months ended September 30, 2010. The difference in the after-tax net loss of $4.8 million for the quarter ended September 30, 2011 and the after-tax net income of $411,000 for the quarter ended September 30, 2010, and the difference in the after-tax net loss of $7.5 million for the nine months ended September 30, 2011 and the after-tax net income of $1.4 million for the nine months ended September 30, 2010 is a result of additional pre-tax provisions for loan losses of approximately $6.9 million and $9.1 million, respectively. The largest factor contributing to the increased provisions is the continued protraction of real estate values in California, and specifically those counties in which the Company operates. At September 30, 2011, the Company’s subsidiary United Security Bank has an estimated total risk-based capital ratio of 13.64%, a Tier 1 capital ratio of 12.41% and a leverage ratio of 9.77%. The Company itself has an estimated total risk-based capital ratio of 13.15%, a Tier 1 capital ratio of 11.89% and a leverage ratio of 9.32% as of September 30, 2011.
