ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On April 19, 2006 United Bancorp, Inc. (the "Company") entered into agreements
providing for severance pay in connection with termination of employment without
cause following a change in control of the Company. The agreements replace
similar agreements in place for such officers and reflect changes necessary to
comply with Section 409A of the Internal Revenue Code.

The agreements are identical with respect to each of the executive officers of
the Company except with regard to the amount of the benefit payable under the
respective agreements. A draft of the agreement executed by each such officer is
attached hereto as Exhibit 10.

In the event of termination of employment, without cause, following a change in
control, the executive is entitled to severance pay equal to a multiple of his
or her then current base salary and cash bonus for the prior year
("Compensation").

On April 19, 2006, the Company also amended its Director Deferred Compensation
Plan to bring the plan into documentary compliance with Section 409A of the
Internal Revenue Code and to expand the plan to permit participation by senior
officers of the Corporation. Directors may defer their cash director fees into
the plan. Senior officers who are named as eligible participants by the
Company's board of directors may elect to defer a portion of their annual cash
bonus into the plan. All plan assets are invested in shares of the Company's
common stock.
