         TECUMSEH, Mich. -- United Bancorp, Inc. reports a strong first quarter
of 2004. Net income reached $1,715,815, which is the company's second best first
quarter ever, and is 3.7% below the first quarter of 2003, which was the
previous record. United's steady growth continued, as assets under management
reached $1.637 billion, an increase of $236.2 million, or 16.9% in the trailing
12 months.

         United achieved steady growth during the quarter, as its loan portfolio
increased by $10.6 million, deposits rose by $11.7 million, and assets under
management in the Trust & Investment Group grew by $29.8 million. The
residential real estate mortgage refinance boom ended late in the third quarter
of 2003, and as a result, mortgage production fell considerably in the fourth
quarter of 2003 and that decline continued in the first quarter of this year.
United's income from loan sales and servicing in the current quarter was
$587,000 less than the prior year. However, its fee income from the Trust &
Investment Group improved by $248,000, or 30.1%, from the first quarter of a
year ago. This strong performance, plus increases in other fee income
categories, offset a substantial portion of the decline in loan sales and
servicing income.

         United Bancorp, Inc. is a financial holding company that is the parent
company for United Bank & Trust and United Bank & Trust -- Washtenaw. The
subsidiary banks operate 17 banking offices in Lenawee, Washtenaw and Monroe
Counties.
