(E) NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

The unaudited condensed consolidated financial statements of United Bancorp,
Inc. (the "Company") have been prepared in accordance with accounting principles
generally accepted in the United States of America for interim financial
information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by accounting principles generally accepted in the United States of America for
complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. The condensed consolidated balance sheet of the
Company as of December 31, 2005 has been derived from the audited consolidated
balance sheet of the Company as of that date. Operating results for the three
and nine month periods ending September 30, 2006 are not necessarily indicative
of the results that may be expected for the year ended December 31, 2006. For
further information, refer to the consolidated financial statements and
footnotes thereto included in the Company's Annual Report on Form 10-K for the
year ended December 31, 2005. Certain amounts for 2005 have been reclassified to
conform to 2006 classifications.

STOCK OPTIONS

In 2004, shareholders approved the Company's 2005 Stock Option Plan (the "2005
Plan"). The plan is a non-qualified stock option plan as defined under Internal
Revenue Service regulations. Under the plan, directors and management of the
Company and subsidiaries are given the right to purchase stock of the Company at
a stipulated price, adjusted for stock dividends, over a specific period of
time. The 2005 Plan will continue in effect until the end of 2009, and is the
only plan in effect in 2006. The 2005 Plan is the successor to the Company's
1999 Stock Option Plan (the "1999 Plan") that continued in effect until the end
of 2004.

The stock subject to the options are shares of authorized and unissued common
stock of the Company. Options under the 1999 and 2005 Plans (the "Plans") are
granted to directors and certain key members of management at the then-current
market price at the time the option is granted. The options have a three- year
vesting period, and with certain exceptions, expire at the end of ten years, or
three years after retirement. The following is summarized option activity for
the 1999 and 2005 Plans, adjusted for stock dividends:



                                        Stock Options
                                ----------------------------

Balance at January 1, 2006        127,192         $51.92
Options granted                    29,525          57.72
Options exercised                  (6,344)         43.02
Options forfeited                  (2,486)         58.91
                                  -------
Balance at September 30, 2006     147,887         $53.34
                                  =======


Total options granted during the nine-month period ended September 30, 2006 were
29,525, and the weighted fair value of the options granted was $7.11. For stock
options outstanding at September 30, 2006, the range of average exercise prices
was $34.11 to $64.29 and the weighted average remaining contractual term was
7.42 years. At September 30, 2006, 74,813 options are exercisable under the
Plans.

Effective January 1, 2006, the Company adopted Statement of Financial Accounting
Standards No. 123(R) Share-Based Payment ("SFAS 123(R)"). SFAS 123(R) addresses
all forms of share-based payment awards, including shares under employee stock
purchase plans, stock options, restricted stock and stock appreciation rights.
SFAS 123(R) requires all share-based payments to be recognized as expense, based
upon their fair values, in the financial statements over the vesting period of
the awards. The Company has


                                     Page 7



elected the modified prospective application method and, as a result, has
recorded approximately $164,005 in compensation expense related to vested stock
options less estimated forfeitures for the nine month period ended September 30,
2006. As of September 30, 2006, unrecognized compensation expense related to the
stock options totaled $311,527 and is expected to be recognized over 3 years.

At September 30, 2006, the aggregate intrinsic value of options outstanding
totaled $213,861. This value represents the difference between the Company's
closing stock price on the last day of trading for the third quarter and the
exercise price multiplied by the number of in-the-money options assuming all
option holders had exercised their stock options on September 30, 2006. No
options were exercised during the quarter ending September 30, 2006.

The following pro forma information presents net income and earnings per share
had SFAS 123 been used to measure compensation cost for stock option grants as
of September 30, 2005. The exercise price of the option grants is equivalent to
the market value of the underlying stock at the grant date, adjusted for stock
dividends. Accordingly, no compensation cost was recorded for the period ended
September 30, 2005.

No valuation allowance was considered necessary for mortgage servicing rights at
period end 2006 and 2005.

NOTE 3 - COMMON STOCK AND EARNINGS PER SHARE

Basic earnings per share are based upon the weighted average number of shares
outstanding plus contingently issuable shares during the year. Diluted earnings
per share further assumes the dilutive effect of additional common shares
issuable under stock options. During April of 2006 and March of 2005, the
Company declared a 5% stock dividend payable in May 2006 and 2005. Earnings per
share, dividends per share and weighted average shares have been restated to
reflect these stock dividends. A reconciliation of basic and diluted earnings
per share follows:

and 7 shares for the nine month periods ended September 30, 2006 and 2005,
represented by stock options granted, are not included in the above calculations
as they are non-dilutive as of the date of this report.

In years prior to 2006, cash dividends were declared in the last month of the
quarter, payable the end of the month following quarter-end. Effective with the
first quarter of 2006, cash dividends are declared and are payable in the month
following the end of the quarter. As a result of this change in schedule, the
cash dividend declared in December of 2005 was paid in January, 2006, but no
dividends were declared in the first quarter of 2006. Subsequently, cash
dividends of $0.37 per share were declared and paid in April and July, 2006.
While this change in procedure has not changed the number of dividends to be
paid during the calendar year, for 2006 the number of cash dividends declared
during the calendar year has been reduced by one.

NOTE 4 - ACCOUNTING DEVELOPMENTS

In March 2006, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standard (SFAS) No. 156. This Statement amends SFAS 140,
Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities, with respect to the accounting for separately recognized
servicing assets and servicing liabilities.

SFAS No. 156 requires an entity to initially recognize a servicing asset or
servicing liability at fair value each time it undertakes an obligation to
service a financial asset by entering into a servicing contract in other
specific situations. In addition, SFAS No. 156 permits an entity to choose
either of the following subsequent measurement methods for each class of
separately recognized servicing assets and servicing liabilities.

     Amortization Method - Amortize servicing assets or servicing liabilities in
     proportion to and over the period of estimated net servicing income or net
     servicing loss and assess servicing assets or servicing liabilities for
     impairment or increased obligation based on fair value at each reporting
     date.

     Fair value measurement method - Measure servicing assets or servicing
     liabilities at fair value at each reporting date and report changes in fair
     value in earnings in the period in which the change occurs.

SFAS No. 156 is effective at the beginning of an entity's fiscal year that
begins after September 15, 2006 and should be applied prospectively for
recognition and initial measurement of servicing assets and servicing
liabilities. Earlier adoption is permitted as of the beginning of an entity's
fiscal year, provided the


                                     Page 9



entity has not yet issued financial statements, including interim financial
statements, for any period of that fiscal year.

The Company did not elect to adopt SFAS No. 156 on January 1, 2006. The Company
is currently evaluating the effect of adopting this Statement on the Company's
financial condition and results of operations.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

This discussion provides information about the consolidated financial condition
and results of operations for United Bancorp, Inc. and its subsidiary banks,
United Bank & Trust ("UBT") and United Bank & Trust - Washtenaw ("UBTW") for the
three and nine month periods ended September 30, 2006 and 2005.

                                   BACKGROUND

The Company is a financial holding company registered with the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board") under the
Bank Holding Company Act. The Company has corporate power to engage in such
activities as permitted to business corporations under the Michigan Business
Corporation Act, subject to the limitations of the Bank Holding Company Act and
regulations of the Federal Reserve System. The Company's subsidiary banks (the
"Banks") offer a full range of services to individuals, corporations,
fiduciaries and other institutions. Banking services include checking, NOW
accounts, savings, time deposit accounts, money market deposit accounts, safe
deposit facilities and money transfers. Lending operations provide real estate
loans, secured and unsecured business and personal loans, consumer installment
loans, and check-credit loans, home equity loans, accounts receivable and
inventory financing, equipment lease financing and construction financing.

The Banks offer the sale of nondeposit investment products through licensed
representatives in their banking offices, and sell credit and life insurance
products. In addition, the Company and/or the Banks are co-owners of Michigan
Banker's Title Insurance Company of Mid-Michigan LLC, and derive income from the
sale of various insurance products to banking clients. UBT operates a trust
department, and provides trust services to UBTW on a contract basis. The trust
department offers a wide variety of fiduciary services to individuals,
corporations and governmental entities, including services as trustee for
personal, corporate, pension, profit sharing and other employee benefit trusts.
The department provides securities custody services as an agent, acts as the
personal representative for estates and as a fiscal, paying and escrow agent for
corporate customers and governmental entities, and provides trust services for
clients of the Banks. These products help to diversify the Company's sources of
income.

Unemployment for the State of Michigan at the end of August, 2006 was 7.1%,
which places it in a tie for the highest rate among the fifty states. The
Lenawee County unemployment rate matches the State's level, while the Washtenaw
County unemployment rate of 4.9% is among the lowest in the State. The Banks
have experienced some slowing of loan growth relating to current economic
conditions. In addition, the Company's loan quality had experienced some
declines toward the end of 2005, but improvement has been noted the past three
quarters. We continue to keep an eye on the softening economy while continuing
our efforts to gain market share.

                                EXECUTIVE SUMMARY

Net income for the third quarter of 2006 was $2,445,449, or $0.922 per share,
representing the Company's best quarter ever, and was 8.0% ahead of the third
quarter of 2005. For the first nine months of 2006, earnings were a record
$6,774,419, or $2.556 per share, increasing 12.8% over the same period of 2005.


                                     Page 10


The Company's strong quarter and year to date performance reflects continued
loan growth and the resulting increase in net interest income. Net interest
income increased 3.2% over the second quarter of 2006, and year to date is 12.6%
over the same period of 2005. Noninterest income was up slightly for the
quarter, and noninterest expense was down modestly.

Return on Average Assets ("ROA") and Return on Average Shareholders' Equity
("ROE") improved from the prior two quarters, with ROA for the quarter reaching
the highest quarterly level in recent quarters. At the same time, ROE for the
quarter was below the levels achieved in the third and fourth quarters of 2005,
but was above the levels achieved in the first and second quarters of this year.
The chart below shows the trends in the major components of earnings for the
past five quarters.

The Company's balance sheet increased by $8.9 million in the third quarter, as
total assets reached $739.9 million at September 30, 2006. This resulted in an
increase of $26.1 million since December 31, 2005, bringing the year to date
annualized asset growth rate to 4.88%. During the current quarter, the Company's
gross loans grew by $17.4 million, deposits increased by $9.1 million, and total
assets were up 4.86% from June 30.

During the second quarter of 2006, the Wealth Management Group of United Bank &
Trust made the decision to exit the business of providing administrative
services for employee benefit accounts, effective September 30, 2006. This
change, along with the decline in market value of assets, has contributed to a
1.8% decrease in total assets managed by the Bank's trust department during the
third quarter of 2006. Assets under management by the trust department declined
$10.7 million during the quarter, with a balance of $568.5 million at September
30, 2006.

                               FINANCIAL CONDITION

SECURITIES

The Company's investment securities portfolio declined by $1.8 million in the
third quarter of 2006, and balances have decrease by $9.0 million since December
31, 2005 as the Company has elected not to replace some maturing investments.
The mix of the Company's investment portfolio has shifted modestly during the
past twelve months, as the percentage of investments held in Treasury, agency
and mortgage backed agency securities has declined and the percentage of
municipal obligations and other investments has increased slightly.

The Company is conservative in its investments, preferring to concentrate its
risks within the loan portfolio. Investments in U.S. Treasury and agency
securities are considered to possess low credit risk. Obligations of U.S.
government agency mortgage-backed securities possess a somewhat higher interest
rate risk due to certain prepayment risks. The corporate, asset backed and other
securities portfolio also contains a moderate level of credit risk. The
municipal portfolio contains a small amount of geographic risk, as less than 11%
of that portfolio is issued by political subdivisions located within Lenawee
County, Michigan. The Company's portfolio contains no "high risk" mortgage
securities or structured notes.

The Company's current and projected tax position continues to make carrying
tax-exempt securities beneficial, and the Company does not anticipate being
subject to the alternative minimum tax in the near future. The investment in
local municipal issues also reflects the Company's commitment to the development
of the local area through support of its local political subdivisions.

LOANS

Gross loans increased by $17.4 million in the third quarter of 2006, bringing
the twelve-month loan growth to $54.8 million, for an increase of 10.2% over the
previous twelve months. All categories of the loan portfolio have experienced
growth during the first nine months of 2006, with business loans and commercial
and residential mortgages providing the largest portion of that growth.

The portfolio continues to evolve and the trend of the portfolio mix has changed
during the first nine months of the year. Personal loans and residential
mortgage balances increased as a percentage of total loans since December 31,
2005 while business loans and construction and development loans experienced a
decline in their overall percentages during the same period.

The table below shows total loans outstanding, in thousands of dollars, and
their percentage of the total loan portfolio. All loans are domestic and contain
no significant concentrations by industry or client.

CREDIT QUALITY

United's loan quality remains strong, in spite of the challenges facing the
Michigan economy. The Company continues to maintain a process of actively
monitoring delinquencies, nonperforming assets and potential problem loans. The
aggregate amount of nonperforming loans is presented in the table below. For
purposes of this summary, loans renewed on market terms existing at the time of
renewal are not considered troubled


                                     Page 12



debt restructurings. The accrual of interest income is discontinued when a loan
becomes ninety days past due unless it is both well secured and in the process
of collection, or the borrower's capacity to repay the loan and the collateral
value appear sufficient.

The Company's total nonperforming assets have declined by more than $4 million
from year-end 2005 totals, with the reduction in all categories of nonperforming
assets. While nonaccrual loan balances increased slightly during the quarter,
delinquent loans and troubled debt restructurings declined by $1.8 million in
the third quarter. Balances of property held as other real estate has also
declined, and the percent of non-performing assets has moved from 1.07% of loans
at December 31, 2005 to 0.48% at September 30, 2006. Collection efforts are
underway with past due and nonaccrual loans, and the Company remains adequately
secured.

The following chart shows the aggregate amount of the Company's nonperforming
assets by type, in thousands of dollars.

As of September 30, 2006, the Company has no loans classified as a troubled debt
restructuring. The amount listed in the table above as other real estate
reflects a small number of properties that were acquired in lieu of foreclosure.
Properties have been leased to a third party with an option to purchase or are
listed for sale, and no significant losses are anticipated.

The Company's allowance for loan losses remains at a level consistent with its
estimated losses, and the allowance provides for currently estimated losses
inherent in the portfolio. An analysis of the allowance for loan losses, in
thousands of dollars, for the nine months ended September 30, 2006 and 2005

Business loans carry the largest balances per loan, and therefore, any single
loss would be proportionally larger than losses in other portfolios. Because of
this, the Company uses an independent loan review firm to assess the continued
quality of its business loan portfolios. This is in addition to the precautions
taken with credit quality in the other loan portfolios. Business loans contain
no significant concentrations other than geographic concentrations within the
market areas served by the Banks.

Loans to finance residential mortgages make up 13.9% of the portfolio at
September 30, 2006, and are well-secured and have had historically low levels of
net losses. Personal and business loans, including business mortgages and
construction and development loans, make up the balance of the portfolio. The
personal loan portfolio consists of direct and indirect installment, credit
cards, home equity and unsecured revolving line of credit loans. Installment
loans consist primarily of loans for consumer durable goods, principally
automobiles. Indirect personal loans consist of loans for automobiles, marine
and manufactured housing.

DEPOSITS

Deposit growth continued during the third quarter of 2006, as total deposits
increased by more than $9 million. This represents an annualized rate of 5.9%,
compared to deposit growth over the past twelve months of 5.3%. Short-term
interest bearing accounts continue to be very popular with clients, and demand
deposit balances increased modestly. The Banks continue to experience interest
by consumers in certificates of deposit, and traditional banking products
continue to be an important part of the Company's product line. In addition, the
Banks have increased their emphasis on gathering core deposits within their
market areas, in order to fund anticipated future loan growth. The Banks'
deposit rates are consistently competitive with other banks in their market
areas.

The majority of the Company's deposits are derived from core client sources,
relating to long term relationships with local personal, business and public
clients. The Banks do not support their growth through brokered deposits,
although they do participate in gathering out-of-market certificates of deposit
through an automated network.

The chart below shows the percentage makeup of the deposit portfolio as of
September 30, 2006 and 2005, and December 31, 2005.

                        LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY, CASH EQUIVALENTS AND BORROWED FUNDS

The Company maintains correspondent accounts with a number of other banks for
various purposes. In addition, cash sufficient to meet the operating needs of
its banking offices is maintained at its lowest practical levels. At times, the
Banks are a participant in the federal funds market, either as a borrower or
seller. Federal funds are generally borrowed or sold for one-day periods. The
Banks also have the ability to utilize short-term advances from the Federal Home
Loan Bank ("FHLB") and borrowings at the discount window of the Federal Reserve
Bank as additional short-term funding sources. Federal funds were used during
2005 and 2006. Short-term advances and discount window borrowings were not
utilized during either year.


                                     Page 14



The Company periodically finds it advantageous to utilize longer term borrowings
from the Federal Home Loan Bank of Indianapolis. These long-term borrowings
serve primarily to provide a balance to some of the interest rate risk inherent
in the Company's balance sheet. No advances matured and no new advances were
obtained during the third quarter of 2006, and the amount of FHLB borrowings
outstanding at September 30 remained substantially unchanged from June 30.

CAPITAL RESOURCES

The capital ratios of the Company exceed the regulatory guidelines for well
capitalized institutions at September 30, 2006 and 2005 and December 31, 2005.

                              RESULTS OF OPERATIONS

Consolidated net income for the third quarter of 2006 resulted in the best
quarter in the Company's history. Net income for the quarter surpassed the
earnings of the second quarter of 2006 by 12.0%, and year to date earnings are
up 12.8% from the same period in 2005. The following discussion provides an
analysis of the various components of these changes.

NET INTEREST INCOME

Net interest income continues to increase, as the Banks continue to benefit from
asset growth and in spite of tightening interest spreads. During the third
quarter, interest income increased by 5.9%, while interest expense grew 10.6%,
resulting in an increase in net interest income of 3.2%. While the Company's
yield on earning assets increased during the quarter, deposit costs increased at
a faster rate, resulting in a slight decrease in spread. Total interest income
was up $683,000 over the second quarter of the year, with most of the
improvement in loan income. Deposit costs provided most of the $454,000 increase
in interest expense, and net interest income was up $229,000 for the quarter.

The Company's year to date yield on earning assets was up ninety-one basis
points from the same period of 2005, while its cost of funds increased from the
nine-month 2005 levels by eighty-three basis points, resulting in an improvement
of seven basis points in the tax equivalent spread. Spread declined from the
second quarter of 2006 by two basis points. Year to date net interest income is
up $2,203,000 over the same period of 2005, or 12.0%.

As noted from the data in the following table, interest income and expense for
the first nine months of 2006 increased from the same period of 2005, and net
interest income improved by just over $2.5 million. During that time, interest
income and interest expense both increased as a result of volume and rate
increases. The improvement in net interest income for the first nine months of
2006 was evenly divided between volume and rate.

The following table shows the effect of volume and rate changes on net interest
income for the nine months ended September 30, 2006 and 2005 on a taxable
equivalent basis, in thousands of dollars.

PROVISION FOR LOAN LOSS

The provision for loan losses for the third quarter of 2006 was $396,000, down
from $440,000 for the second quarter of 2006 and up from $329,000 for the third
quarter of last year. Through nine months, the provision is $248,000 higher than
the first nine months of 2005, for an increase of 26.0%. The increase in the
provision for loan losses for the quarter and year to date is directly related
to the continued growth of the Company's loan portfolio.

NONINTEREST INCOME

Noninterest income increased 2.4% from the second quarter of 2006 and improved
2.1% over the third quarter of 2005. Service charges on deposits, income from
the sale of nondeposit investment products and income from loan sales and
servicing provided the improvement for the quarter, while Trust & Investment fee
income was flat and other income was down from the prior quarter.

Year to date, noninterest income is up 4.1% from the same period of 2005, with
improvement in all categories of noninterest income other than Trust and
investment fee income and income from loan sales and servicing. The declines in
Trust income are a result of a number of items, including the department's exit
of the employee benefits business during the second and third quarters. The
decline in income from the sale and servicing of mortgage loans reflects lower
volumes of loans sold on the secondary market. The largest dollars of increase
were from deposit service charges, ATM, debit and credit card income and income
from the sale of nondeposit investment products.


                                     Page 17



The Banks generally market their production of fixed rate long-term mortgages in
the secondary market, and retain adjustable rate mortgages for their portfolios.
The Company maintains a portfolio of sold residential real estate mortgages,
which it continues to service. This servicing provides ongoing income for the
life of the loans. No write downs in mortgage servicing rights were required in
2006 or 2005.

NONINTEREST EXPENSES

Total noninterest expense decreased slightly during the third quarter compared
to the second quarter of 2006, with no significant changes in any one category.
Total year to date noninterest expense is up 7.9% from the same period of 2005.
Most categories of noninterest expense have increased during that period, with
compensation expense, professional fees and external data processing providing
the largest increases. Professional fees have grown in 2006 as a result of
additional consulting expenses and the Company's branding initiative. Increases
in external data processing costs relate primarily to the costs of ATM, debit
card, credit card and merchant processing, but also reflect a shift to
outsourcing of the Company's Trust processing during the third quarter of 2006.
The increase in expenses generally reflects the continued growth of the Company.

FEDERAL INCOME TAX

The Company's effective tax rate for the third quarter was up slightly, at
28.3%; compared to 27.7% for the second quarter. The Company's effective tax
rate for the first nine months of the year increased slightly from 2005 to 2006,
at 27.8% for 2006, compared to 27.6% for 2005.

NET INCOME

Overall, net interest income continues to be the major factor behind the
Company's strong net income. Noninterest income growth will likely slow as the
Company's income from loan sales and servicing and trust and investment fee
income flattens and overall noninterest income levels become more dependent on
other categories of income. Expenses remain at acceptable levels, but will also
increase during the remainder of the year as the Company expands its markets and
fills currently-vacant staff positions.

CRITICAL ACCOUNTING POLICIES

Generally accepted accounting principles are complex and require management to
apply significant judgments to various accounting, reporting and disclosure
matters. The Company's Management must use assumptions and estimates to apply
these principles where actual measurement is not possible or practical. For a
complete discussion of the Company's significant accounting policies, see "Notes
to the Consolidated Financial Statements" on pages A-26 to A-29 of the Company's
Annual Report on Form 10-K for the year ended December 31, 2005. Certain
policies are considered critical because they are highly dependent upon
subjective or complex judgments, assumptions and estimates. Changes in such
estimates may have a significant impact on the financial statements. Management
has reviewed the application of these policies with the Audit Committee of the
Company's Board of Directors.

FORWARD-LOOKING STATEMENTS

Statements contained in Management's Discussion and Analysis of Financial
Condition and Results of Operations include forward-looking statements that are
based on management's beliefs, assumptions, current expectations, estimates and
projections about the financial services industry, the economy, and about the
Company itself. Words such as "anticipate," "believe," "determine," "estimate,"
"expect," "forecast," "intend," "is likely," "plan," "project," "opinion,"
variations of such terms, and similar expressions are intended to identify such
forward-looking statements. The presentations and discussions of the provision


                                    Page 18



and allowance for loan losses, and determinations as to the need for other
allowances presented in this report are inherently forward-looking statements in
that they involve judgments and statements of belief as to the outcome of future
events. These statements are not guarantees of future performance and involve
certain risks, uncertainties, and assumptions that are difficult to predict with
regard to timing, extent, likelihood, and degree of occurrence. Therefore,
actual results and outcomes may materially differ from what may be expressed or
forecasted in such forward-looking statements. Internal and external factors
that may cause such a difference include those discussed under "Risk Factors" in
Part I, Item 1A of the Company's Annual Report on Form 10-K for the year ended
December 31, 2005, and generally include changes in interest rates and interest
rate relationships; demand for products and services; the degree of competition
by traditional and non-traditional competitors; changes in banking laws and
regulations; changes in tax laws; changes in prices, levies, and assessments;
the impact of technological advances; governmental and regulatory policy
changes; the outcomes of pending and future litigation and contingencies; trends
in customer behavior and customer ability to repay loans; software failure,
errors or miscalculations; and the vicissitudes of the national economy. The
Company undertakes no obligation to update, amend or clarify forward-looking
statements, whether as a result of new information, future events, or otherwise.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

FUNDS MANAGEMENT AND INTEREST RATE RISK

The composition of the Company's balance sheet consists of investments in
interest earning assets (loans and investment securities) that are funded by
interest bearing liabilities (deposits and borrowings). These financial
instruments have varying levels of sensitivity to changes in market interest
rates resulting in market risk. Policies place strong emphasis on stabilizing
net interest margin, with the goal of providing a sustained level of
satisfactory earnings. The Funds Management, Investment and Loan policies
provide direction for the flow of funds necessary to supply the needs of
depositors and borrowers. Management of interest sensitive assets and
liabilities is also necessary to reduce interest rate risk during times of
fluctuating interest rates.

A number of measures are used to monitor and manage interest rate risk,
including interest sensitivity and income simulation analyses. An interest
sensitivity model is the primary tool used to assess this risk with supplemental
information supplied by an income simulation model. The simulation model is used
to estimate the effect that specific interest rate changes would have on twelve
months of pretax net interest income assuming an immediate and sustained up or
down parallel change in interest rates of 200 basis points. Key assumptions in
the models include prepayment speeds on mortgage related assets; cash flows and
maturities of financial instruments held for purposes other than trading;
changes in market conditions, loan volumes and pricing; and management's
determination of core deposit sensitivity. These assumptions are inherently
uncertain and, as a result, the models cannot precisely estimate net interest
income or precisely predict the impact of higher or lower interest rates on net
interest income. Actual results will differ from simulated results due to
timing, magnitude, and frequency of interest rate changes and changes in market
conditions.

Based on the results of the simulation model as of September 30, 2006, the
Company would expect a maximum potential reduction in net interest margin of
less than 6% if market rates decreased under an immediate and sustained parallel
shift of 200 basis points. The interest sensitivity position of the Company is
now slightly liability sensitive, a change in trend from the asset sensitive
position the Company had experienced.


                                    Page 19



The Company and each Bank maintains Funds Management Committees, which review
exposure to market risk on a regular basis. The Committees' overriding policy
objective is to manage assets and liabilities to provide an optimum and
consistent level of earnings within the framework of acceptable risk standards.
The Funds Management Committees are also responsible for evaluating and
anticipating various risks other than interest rate risk. Those risks include
prepayment risk, credit risk and liquidity risk. The Committees are made up of
senior members of management, and monitor the makeup of interest sensitive
assets and liabilities to assure appropriate liquidity, maintain interest
margins and to protect earnings in the face of changing interest rates and other
economic factors.

The Funds Management policies provide for a level of interest sensitivity which,
Management believes, allows the Banks to take advantage of opportunities within
their markets relating to liquidity and interest rate risk, allowing flexibility
without subjecting the Company to undue exposure to risk. In addition, other
measures are used to evaluate and project the anticipated results of
Management's decisions.

ITEM 4 - CONTROLS AND PROCEDURES

INTERNAL CONTROL

The Company maintains internal controls that contain self-monitoring mechanisms,
and actions are taken to correct deficiencies as they are identified. The Board
of Directors of the Company, operating through its Audit and Compliance
Committee, provides oversight to the financial reporting process. Even effective
internal controls, no matter how well designed, have inherent limitations,
including the possibility of circumvention or overriding of controls.
Accordingly, even effective internal controls can provide only reasonable
assurance with respect to financial statement preparation. Furthermore, the
effectiveness of internal controls may vary over time. The Company's Audit and
Compliance Committee is composed entirely of Directors who are not officers or
employees of the Company.

As of September 30, 2006, an evaluation was carried out under the supervision
and with the participation of United Bancorp's management, including our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of our
disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e)
and 15d-15(e) under the Securities Exchange Act of 1934). Based on their
evaluation, our Chief Executive Officer and Chief Financial Officer have
concluded that United Bancorp's disclosure controls and procedures as of the end
of the quarter ended September 30, 2006 are, to the best of their knowledge,
effective to reasonably ensure that information required to be disclosed by the
Company in reports that it files or submits under the Exchange Act are recorded,
processed, summarized and reported within the time periods specified in
Securities and Exchange Commission rules and forms. There have been no changes
in the Company's internal controls over financial reporting that occurred during
the quarter ended September 30, 2006 that materially affected, or are likely to
materially affect, the Company's internal control over financial reporting.

                                     PART II
                                OTHER INFORMATION

ITEM 1- LEGAL PROCEEDINGS

On September 22, 2006, Annette Theisen and various entities controlled by her,
filed a complaint in Washtenaw Circuit Court against a number of defendants,
including UBTW and its President, Todd C. Clark. The complaint alleges that UBTW
and its President had a fiduciary duty and a duty of good faith to plaintiffs
and that UBTW and its President breached those duties in connection with secured
loans made to plaintiffs by, among other things, allegedly allowing plaintiffs
to make imprudent investments with such loans, causing transfers of, and
mortgages to be placed on, certain of plaintiffs' assets contrary to plaintiffs'
interests, not disclosing certain alleged conflicts of interest, and failing to
pay the premium on, and causing


                                    Page 20



the cancellation of, Ms. Theisen's long-term supplemental medical insurance
policy. Plaintiffs seek damages of $6 million. The Company intends to vigorously
defend such claims.

The Company is not involved in any material legal proceedings. In addition to
the foregoing litigation, the Company and the Banks are involved in ordinary
routine litigation incident to its business; however, no such routine
proceedings are expected to result in any material adverse effect on the
operations or earnings of the Company or the Banks. Neither the Company nor the
Banks are involved in any proceedings to which any director, principal officer,
affiliate thereof, or person who owns of record or beneficially five percent
(5%) or more of the outstanding stock of the Company, or any associate of the
foregoing, is a party or has a material interest adverse to the Company or the
Banks.
