TECUMSEH, MI - United Bancorp, Inc. (UBMI.OB) reports a record second quarter in
2006 and record earnings for the first six months of 2006, as it continues to
manage through a flat yield curve and the Federal Reserve Board's continued
increase in short-term interest rates.

Net income for the second quarter of 2006 was $2,184,379, representing the
Company's best second quarter ever, and 11.6% ahead of the second quarter of
2005. For the first half of 2006, earnings were a record $4,328,970, increasing
15.7% over the first half of 2005. The Company's strong performance during the
first half of 2006 is primarily the result of continued loan growth of $44
million or 8.5% over June 30, 2005, and the resulting increase in net interest
income, which was up 13.7% over the first half of 2005.

At its meeting of July 11, 2006, the board of directors of United Bancorp, Inc.
declared a cash dividend of 37 cents per share payable July 31, 2006 to
shareholders of record July 21, 2006. This represents the same per share amount
paid earlier this year but represents a 5% increase as it is reflective of the
new shares that resulted from the stock dividend paid on May 31, 2006.

Bancorp, Inc. is in the top quartile of public banks in Michigan, Indiana, Ohio
