              Item 4. Changes in Registrant's Certifying Accountant

(a) On April 22, 1997, the Audit Committee of United Security Bancorporation
(the "Company") accepted the decision of the firm of McFarland & Alton, P.S.
("McFarland & Alton") to decline to stand for re-election as the independent
auditor for the Company and its subsidiaries.

(b) McFarland & Alton's Audit Report on the Company's financial statements for
the years ended December 31, 1995, and December 31, 1996, did not contain an
adverse opinion or a disclaimer of opinion nor was it qualified or modified as
to uncertainty, audit scope, or accounting principles.

(c) During McFarland & Alton's audit of the Company's 1996 financial statements,
McFarland & Alton noted matters involving the internal control structure and its
operation that they considered to be reportable conditions under standards
established by the American Institute of Certified Public Accountants.
McFarland & Alton also stated in a communication with the Audit Committee:


                                        1

   2
        There were disagreements with management regarding the materiality,
        accounting treatment, and necessary disclosures related to the Home
        Security Bank fraud loss. There was also a disagreement related to the
        existence of sufficient competent evidential matter supporting the
        insurance recoverability of the fraud loss as of the date of our report.
        These disagreements were satisfactorily resolved and management agreed
        to record the identified fraud loss and to disclose the uncertainties
        surrounding the recovery from insurance and the potential for additional
        losses.

All of the foregoing matters have been discussed and noted in communications
with the Company's Audit Committee.

(d) The Audit Committee for the Company is presently in the process of selecting
a new independent auditor. The Company's Audit Committee has authorized
McFarland & Alton to respond fully to inquiries of the successor accountants.
The Company will file a Form 8-K when the selection of the new auditor has been
made.

(e) A letter from McFarland & Alton addressed to the Securities and Exchange
Commission is included as Exhibit 16 to this Form 8-K.

                 Item 6. Resignations of Registrant's Directors

(a) On April 21, 1997, Stan Horton, a Director of the United Security
Bancorporation (the "Company") tendered his resignation from the Board of
Directors of the United Security Bancorporation and any and all of its
subsidiaries. Director Horton stated the basis for his resignation was his lack
of faith in the internal control structure and the personnel in charge of these
controls.

(b) The Company has and has had in place what it believes to be appropriate
internal control policies and procedures. The fraud loss was the result of
circumvention of these policies and procedures. In response to the fraud loss,
the Company has taken steps to further tighten and improve these polices and
procedures.

(c) A copy of the Director's letter is included as Exhibit 17 to this Form 8-K.

                    Item 7. Financial Statements and Exhibits
