             UNITED BANCORP, INC. DECLARES CASH AND STOCK DIVIDENDS
                    AND ANNOUNCES FIRST QUARTER 2007 EARNINGS

TECUMSEH, MI - United Bancorp, Inc. (UBMI) announced that it has increased its
quarterly dividend amount to $0.40 per share and has declared a 100% stock
dividend. In addition, the Company reported net income of $1.726 million or
$0.65 per share for the quarter ended March 31, 2007, compared to $2.145 million
or $0.81 per share for the first quarter of 2006 and $2.197 million or $0.83 per
share for the fourth quarter of 2006.

Cash and Stock Dividends Declared

Robert K. Chapman, President and Chief Executive Officer of United Bancorp, Inc.
("United") announced that the board of directors of United Bancorp, Inc. has
declared a cash dividend of $0.40 per share payable April 30, 2007 to
shareholders of record April 20, 2007. This dividend represents an increase
of 5.3%, or $0.02 per share over the cash dividend paid in the first quarter
of this year.

In addition, the board of directors of United has declared a 100% stock dividend
payable May 31, 2007 to shareholders of record May 11, 2007. As a result of this
stock dividend, shareholders of United Bancorp, Inc. stock will receive one
additional share of stock for each share they currently own.

Financial Performance

Additions to the Company's allowance for loan losses reduced net income during
the first quarter of 2007, resulting in a decline in net income from prior
quarters. Net interest income for the first quarter of 2007 was up over the same
quarter last year. Noninterest income continues to improve, and expenses are
down from the same period last year. At the same time, United continues to grow
the company, and balances in the loan portfolio have increased by $56.0 million
from a year ago. Mr. Chapman noted that "While we experienced a decline in
earnings as a result of the additional provision for loan loss, our core
earnings remain strong."

The Company's interest income was up 12.0% in the first quarter compared to the
first quarter of 2006 while interest expense increased by 32.2%, and net
interest income increased by 1.2%. During the first quarter of this year, net
interest margin was 4.30%, down from 4.52% for the same period of 2006.
Chapman commented, "We continue to face the challenge of a flat to inverted
yield curve and the resulting negative pressure on our net interest income."

In the first quarter of 2007, the Company's provision for loan loss was $1.509
million, up from $365,900 for the first quarter of 2006. The increase in
provision relates to the Company's recognition of impairment of a few large
business loans and the Company's corresponding increase in the amount of its
Allowance for Loan Losses at March 31, 2007.

Total noninterest income for the first quarter increased $318,100 over the same
quarter of 2006, representing an improvement of 11.0% for the period. Continued
improvement in income from fees, wealth management services and mortgage loan
sales and servicing has contributed to the improvement in noninterest income.

Total noninterest expenses for the period were down 1.4% from the same quarter
last year. While some expense categories were higher than the prior year, the
increases were more than offset by declines in compensation expense and costs of
external data processing.

Financial Condition

Loans totaled $615.1 million at March 31, 2007, up from $559.1 million at March
31, 2006. Deposit growth for the past year was somewhat slower than loan growth,
but new deposits of $33.2 million brought the quarter end total deposits to
$636.4 million. Total consolidated assets at March 31, 2007 were $760.5 million,
up from $718.3 million at the end of the first quarter of 2006. Loan growth for
the past twelve months was 10.0%, with deposit growth of 5.5% and total asset
growth of 5.9%.
