ITEM 4.01.        CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

(a)  On July 10, 2007, Grant Thornton LLP ("Grant Thornton") was terminated as
the independent registered public accountant for United Bancorp, Inc. ("United"
or the "Corporation"). On July 10, 2007, the Audit Committee of the
Corporation's Board of Directors, upon authority delegated to it by the Board of
Directors, engaged the firm of BKD, LLP as the Corporation's new independent
registered public accountant.

(b)  Grant Thornton's reports on the consolidated financial statements of the
Corporation for each of the fiscal years ended December 31, 2005 and December
31, 2006, contained no adverse opinions or disclaimers of opinion, and none were
qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2005 and December 31, 2006, and the
subsequent interim period through July 10, 2007, there were no disagreements
between the Corporation and Grant Thornton on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which disagreements, if not resolved to the satisfaction of Grant
Thornton, would have caused it to make reference to the subject matter of the
disagreement in connection with its reports. During the fiscal years ended
December 31, 2004, December 31, 2005 and December 31, 2006, and the subsequent
interim period through July 10, 2007, there were no reportable events as defined
in Item 304 (a)(1)(v) of SEC Regulation S-K.

(c)  During the fiscal years ended December 31, 2005 and December 31, 2006, and
the subsequent interim period through July 10, 2007, the Corporation did not
consult with BKD, LLP regarding any of the matters or events set forth in Item
304(a)(2)(i) and (ii) of SEC Regulation S-K.

     Exhibit No. 16, filed herewith, sets forth the letter of Grant Thornton to
the Commission stating whether Grant Thornton agrees with the statements made by
Registrant in this report on Form 8-K and the respects, if any, in which Grant
Thornton does not agree with Registrant's statements in this report on Form 8-K.
