                         UNITED BANCORP, INC. ANNOUNCES
                           FIRST QUARTER 2008 EARNINGS

TECUMSEH, MI - United Bancorp, Inc. (UBMI), reported net income of $1,888,100 or
$.37 per share for the quarter ended March 31, 2008, compared to $1,726,000 or
$.33 per share for the same quarter of 2007. Return on average shareholders'
equity (ROE) for the quarter was 10.35%, compared to 9.35% for the first quarter
of last year, and return on average assets (ROA) for the most recent quarter was
..94%, up from .92% for the same period last year.

Financial Performance

Net income for the quarter improved from that of one year ago, and was
significantly better than the earnings achieved in the fourth quarter of 2007.
For the quarter, total revenues increased by nearly 5%. United's net interest
income increased by 2.5% during the most recent quarter compared to a year ago
as growth in assets was offset by tightening interest spreads due to market rate
shifts and continued competition for funding.

Total noninterest income for the quarter of $3.54 million reflects an
improvement of 10.2% over first quarter 2007 levels, with income from loan sales
and servicing providing the largest increases. The Company's residential
mortgage business continued to expand as loan originations increased 45%
compared with the same period in 2007. In addition, the recently formed United
Structured Finance Company contributed to the Company's noninterest income
during the quarter, and the Company's wealth management group continued to
provide a significant contribution to revenue. Total noninterest expense
increased compared to the same period last year, with a significant portion of
that resulting from selective increases in staffing and higher benefit costs.

Asset Quality

The Company's provision for loan loss for the first quarter of 2008 was
$660,000, down significantly from $1.5 million for the same quarter of 2007. At
this level, the provision expense is also considerably below that of the fourth
quarter of 2007, when the Company's provision was $5.8 million. Management
continues to be concerned for economic conditions within Michigan and the market
areas of its banks, but remains diligent in addressing credit issues in its loan
portfolio. At March 31, 2008, the Company's allowance for loan loss was 1.84% of
total loans, substantially unchanged from the end of 2007, and up from 1.51% at
March 31, 2007. The Company's ratio of total nonperforming loans to total loans
increased from 2.35% at December 31, 2007 to 2.48% at March 31, 2008. At the end
of the current quarter, non-performing loans totaled $16.2 million, compared to
$10.9 million one year earlier and $15.2 million at the end of 2007.

Financial Condition

Total consolidated assets of the Company of $797.9 million at March 31, 2008
were up 4.9% from the same period last year, and increased by $2.2 million
during the most recent quarter. At the end of March, loan balances reached
$655.0 million, for an increase of $10.4 million in the quarter, and loan growth
was $43.1 million over the past year. Deposits at March 31, 2008 were $667.5
million, an increase of 4.9% compared with the prior year balance.
