                         UNITED BANCORP, INC. ANNOUNCES
                          SECOND QUARTER 2008 EARNINGS

TECUMSEH, MI - United Bancorp, Inc. (UBMI), reported net income of $1,695,300 or
$.33 per share for the quarter ended June 30, 2008, compared to $2,267,200 or
$.43 per share for the same quarter of 2007. Earnings for the first six months
of 2008 were $3,583,400, or $.70 per share, compared to $3,993,200, or $.75 per
share for the same period of 2007.

Financial Performance

Additions to the Company's allowance for loan losses reduced net income during
the second quarter of 2008, resulting in a decline in net income from the prior
quarter and the same quarter of 2007. While loan quality and competitive pricing
pressure have continued to negatively impact the Company's net interest margin,
non-interest income has increased 12.8% over the same quarter of 2007 and now
represents 33% of total revenue. Robert K. Chapman, President and Chief
Executive Officer of United Bancorp, noted "We continue to address the issues of
tightening margin and credit quality resulting from the current economic
conditions, while building on our strengths to grow our noninterest income."

Asset Quality

In the second quarter of 2008, the Company's provision for loan loss was $1.65
million, up from $710,000 for the same quarter of 2007, bringing the provision
for the first six months of 2008 to $2.31 million. This compares to a provision
of $2.22 million for the same period of 2007, for an increase of 4.1%. The
increase in provision relates to the Company's recognition of potential losses
relating to a few large business loans and the Company's corresponding increase
in the amount of its Allowance for Loan Losses at June 30, 2008.

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 June 30, 2008, the Company's allowance for loan loss
was 1.96% of total loans, up slightly from the end of the first quarter, and up
from 1.19% at June 30, 2007. The Company's ratio of total nonperforming loans to
total loans increased from 2.48% at March 31, 2008 to 2.65% at June 30, 2008. At
the end of the current quarter, non-performing loans totaled $17.5 million,
compared to $16.2 million at the end of the first quarter of 2008 and $7.5
million one year earlier.

Financial Condition

Total consolidated assets of the Company of $798.9 million at June 30, 2008 were
up 2.2% from the same period last year. At the end of June, portfolio loan
balances reached $662.0 million, up 4.4% from June 30, 2007, and loan growth was
$28.0 million over the past year. Deposits at June 30, 2008 were $669.1 million,
for an increase of 1.9% compared with the prior year balance.
