ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On January 11, 2006, the Board of Directors of United Bancorp, Inc. approved
employment contracts for 2006 and bonuses for 2005 for its executive officers.

The employment contracts include the following provisions:

     1.   Term of contracts is twelve months

     2.   Termination for cause results in compensation paid to the date of
          termination.

     3.   Unless terminated for cause by mutual agreement, any other termination
          provides for continuation of salary for six months, which shall cease,
          however, if the employee secures employment sooner.

     4.   In the event of change in control, if the employee is terminated or
          leaves on his own accord within twelve months of the date of change in
          control, the employee will receive continuation of salary for twelve
          months.

     5.   Confidential information is the property of the Company.

     6.   The terminated employee is prohibited from soliciting employees or
          clients of the Company or subsidiary banks for one year following
          termination.

     7.   Provides a non-compete clause within the subsidiary bank CRA areas for
          a term of one year.

     8.   Disputes will be resolved by arbitration.

These terms are unchanged from prior years. 2005 bonus and 2006 salary amounts
are set forth in the table below.
