                                     PART I


 ITEM 1 - BUSINESS
 United Bancorp, Inc. (the "Company") was incorporated on May 31, 1985 as a
 business corporation under the Michigan Business Corporation Act, pursuant to
 the authorization and direction of the Directors of United Bank & Trust
 ("UBT").

 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. In general, the Bank Holding Company
 Act and regulations restrict the Company with respect to its own activities and
 activities of any subsidiaries to the business of banking or such other
 activities which are closely related to the business of banking.

 United Savings Bank (the "Bank") opened in 1933 as a result of a merging of
 charters of Lilley State Bank and Tecumseh State Savings Bank. Since that time,
 the Bank has grown from a single office in Tecumseh to sixteen offices located
 in three counties in Southeast Michigan. The Bank changed its name to United
 Bank & Trust on January 1, 1992, at the time it acquired Thompson Savings Bank
 in Hudson, and UBT was acquired by the Company on January 1, 1986.

 UBT delivers financial services through a system of sixteen banking offices
 plus fifteen automated teller machines, all in Lenawee, Washtenaw, and Monroe
 Counties, Michigan. The business base of the area is primarily agricultural and
 light manufacturing, with its manufacturing sector exhibiting moderate
 dependence on the automotive and refrigeration and air conditioning industries.

 In November of 2000, the Company filed applications with its regulators for
 permission to establish a second bank as a subsidiary of the Company. United
 Bank & Trust - Washtenaw ("UBTW") opened for business on April 2, 2001, and is
 headquartered in Ann Arbor. UBTW operates with its own local management and
 board of directors, and targets the Washtenaw County market for its growth.

 Banking services are delivered by UBTW through one banking office and one
 off-site automated teller machine in Washtenaw County, Michigan. The employment
 base of Washtenaw County is centered around health care, education and
 automotive high technology. Economic stability is provided to a great extent by
 the University of Michigan, which is a major employer and is not as
 economically sensitive to the fluctuations of the automotive industry. The
 services and public sectors account for a substantial percentage of total
 industry employment, in a large part due to the University of Michigan and the
 U of M Medical Center.

 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, credit card and check-credit loans,
 home equity loans, accounts receivable and inventory financing, equipment lease
 financing and construction financing.

 The Banks maintain correspondent bank relationships with a small number of
 larger banks, which involve check clearing operations, securities safekeeping,
 transfer of funds, loan participation, and the purchase and sale of federal
 funds and other similar services. UBTW also maintains a correspondent banking
 relationship with UBT.



                                     Page 3




 The Company's 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 Michigan
 Bankers Insurance Center, LLC, and derive income from the sale of various
 insurance products to banking clients.

 The following table shows comparative information concerning the Banks as of
 December 31, 2002, in thousands of dollars:




                                                                  Assets      Loans      Deposits
                                                                ---------   ---------    ---------

         United Bank & Trust - Washtenaw                           60,304      54,646       37,592


 UBT operates a trust department, and provides trust services to UBTW on a
 contract basis. The Trust & Investment Group 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.

 Supervision and Regulation
 As a bank holding company within the meaning of the Bank Holding Company Act,
 the Company is required by said Act to file quarterly and annual reports of its
 operations and such additional information as the Federal Reserve Board may
 require and is subject, along with its subsidiaries, to examination by the
 Federal Reserve Board. The Federal Reserve is the primary regulator of the
 Company.

 The Bank Holding Company Act requires every bank holding company to obtain
 prior approval of the Federal Reserve Board before it may merge with or
 consolidate into another bank holding company, acquire substantially all the
 assets of any bank, or acquire ownership or control of any voting shares of any
 bank if after such acquisition it would own or control, directly or indirectly,
 more than 5% of the voting shares of such bank holding company or bank. The
 Federal Reserve Board may not approve the acquisition by the Company of voting
 shares or substantially all the assets of any bank located in any state other
 than Michigan unless the laws of such other state specifically authorize such
 an acquisition. The Bank Holding Company Act also prohibits a bank holding
 company, with certain exceptions, from acquiring direct or indirect ownership
 or control of more than 5% of the voting shares of any company which is not a
 bank and from engaging in any business other than that of banking, managing and
 controlling banks or furnishing services to banks and their subsidiaries.
 However, holding companies may engage in, and may own shares of companies
 engaged in, certain businesses found by the Federal Reserve Board to be so
 closely related to banking or the management or control of banks as to be a
 proper incident thereto.

 Under current regulations of the Board of Governors, a holding company and its
 nonbank subsidiaries are permitted, among other activities, to engage, subject
 to certain specified limitations, in such banking related business ventures as
 sales and consumer finance, equipment leasing, computer service bureau and
 software operations, data processing and services transmission, discount
 securities brokerage, insurance, mortgage banking and brokerage, sale and
 leaseback and other forms of real estate banking. The Bank Holding Company Act
 does not place territorial restrictions on the activities of nonbank
 subsidiaries of bank holding



                                     Page 4




 companies. In addition, federal legislation prohibits acquisition of "control"
 of a bank or bank holding company without prior notice to certain federal bank
 regulators. "Control" in certain cases may include the acquisition of as little
 as 10% of the outstanding shares of capital stock.

 In March of 2000, the Gramm-Leach-Bliley Act of 1999 (the "GLB Act") was
 enacted. Under the act, new opportunities became available for banks and other
 depository institutions, insurance companies and securities firms to enter into
 combinations that permit a single financial services organization to offer
 customers a more complete array of financial products and services. The GLB Act
 provides a new regulatory framework for regulation through the "financial
 holding company," with the Federal Reserve Board as the umbrella regulator.
 Functional regulation of the separately regulated subsidiaries of a financial
 holding company will be conducted by their primary functional regulator.

 In order to qualify as a financial holding company, a bank holding company must
 file an election to become a financial holding company and each of its banks
 must be "well capitalized" and "well managed." In addition, the GLB Act
 requires satisfactory or above Community Reinvestment Act compliance for
 insured depository institutions and their financial holding companies in order
 for them to engage in new financial activities. The GLB Act provides a federal
 right to privacy of non-public personal information of individual customers.
 The Company and its Banks are also subject to certain state laws that deal with
 the use and distribution of non-public personal information. The Company
 believes that the GLB Act could significantly increase competition in its
 business, and the Company elected to become a financial holding company during
 2000.

 Michigan's banking laws restrict the payment of cash dividends by a state bank
 by providing, subject to certain exceptions, that dividends may be paid only
 out of net profits then on hand after deducting therefrom its losses and bad
 debts and no dividends may be paid unless the bank will have a surplus
 amounting to not less than twenty percent (20%) of its capital after the
 payment of the dividend.

 UBT and UBTW are Michigan banking corporations, and as such are subject to the
 regulation of, and supervision and regular examination by, the Michigan
 Division of Financial Institutions ("DFI") and also the Federal Deposit
 Insurance Corporation ("FDIC"). The DFI is the primary regulator of the Banks.
 Deposit accounts of the Banks are insured by the FDIC. Requirements and
 restrictions under the laws of the United States and the State of Michigan
 include the requirement that banks maintain reserves against certain deposits,
 restrictions on the nature and amount of loans which may be made by a bank and
 the interest that may be charged thereon, restrictions on the payment of
 interest on certain deposits and restrictions relating to investments and other
 activities of a bank.

 The Federal Reserve Board has established guidelines for risk-based capital by
 bank holding companies. These guidelines establish a risk adjusted ratio
 relating capital to risk-weighted assets and off-balance-sheet exposures. These
 capital guidelines primarily define the components of capital, categorize
 assets into different risk classes, and include certain off-balance-sheet items
 in the calculation of capital requirements. Tier I capital consists of
 shareholders' equity less intangible assets and unrealized gain or loss on
 securities available for sale, and Tier 2 capital consists of Tier 1 capital
 plus qualifying loan loss reserves.

 The capital ratios of the Company and Banks exceed the regulatory guidelines
 for well capitalized institutions, and in conjunction with regulatory ratings,
 have qualified the Bank for the lowest FDIC insurance rate available to insured
 financial institutions. Information in Note 18 on Page A-35 of the Company's
 Proxy provides additional information regarding the Company's capital ratios,
 and is incorporated herein by reference.

 Information regarding accounting standards adopted by the Company are discussed
 beginning on Page A-24 of the Company's Proxy, and is incorporated herein by
 reference.

 Competition
 The banking business in the Company's service area is highly competitive. In
 its market, the Banks compete with credit unions, savings associations, and
 various finance companies and loan production offices. This competition is in
 addition to a number of community banks and subsidiaries of large multi-state,
 multi-bank holding companies.

 The Company believes that the market perceives a competitive benefit to an
 independent, locally controlled commercial bank. Much of the Company's
 competition comes from affiliates of organizations controlled from outside the
 area. Against these competitors, the subsidiary banks continue to expand their
 loan and deposit portfolios. Coupled with the fact that the Company offers the
 only locally-based trust department in Lenawee County, this local focus has
 provided a significant competitive advantage.

 Employees
 On December 31, 2002, the Company and its subsidiaries employed 183 full-time
 and 52 part-time employees. This compares to 188 full time and 54 part time
 employees as of December 31, 2001. The Company has no full time employees. Its
 operation and business are carried out by officers and employees of the Banks,
 who are not compensated by the Company.

 Additional information concerning nonperforming loans, the Company's nonaccrual
 policy, and loan concentrations is provided on Pages A-8, A-9 and A-10, in Note
 1 on Pages A-24 and A-25 and Notes 5 and 6 on Pages A-28 and A-29 of the
 Company's Proxy Statement, and is incorporated herein by reference.

 At December 31, 2002, the Banks had two loans, other than those disclosed
 above, for a total of $313,000 which would cause management to have serious
 doubts as to the ability of the borrowers to comply with the present loan
 repayment terms. These loans were included on the Banks' "watch lists" and were
 classified as impaired; however, payments are current.

 (D)     OTHER INTEREST BEARING ASSETS
 As of December 31, 2002, other than $467,000 in other real estate, there were
 no other interest bearing assets that would be required to be disclosed under
 Item III, Parts (C)(1) or (C)(2) of the Loan Portfolio listing if such assets
 were loans.

 The allowance for loan losses is maintained at a level believed adequate by
 Management to absorb losses inherent in the loan portfolio. Management's
 determination of the adequacy of the allowance is based on an


                                     Page 8




 evaluation of the portfolio, past loan loss experience, current economic
 conditions, volume, amount and composition of the loan portfolio, and other
 factors. The provision charged to earnings was $1,105,000 in 2002, compared to
 $722,000 in 2001 and $1,129,000 in 2000. The allowance is based on the analysis
 of the loan portfolio and a four year historical average of net charge offs to
 average loans of 0.15% of the portfolio.

 The following table presents the portion of the allowance for loan losses

 ITEM 14 -           CONTROLS AND PROCEDURES

 (a)     The term "disclosure controls and procedures" is defined in Rules
         13a-14(C)and 15d-14(C)of the Securities Exchange Act of 1934 (the
         "Exchange Act"). These rules refer to the controls and other procedures
         of a company that are designed to ensure that information required to
         be disclosed by a company in the reports that it files under the
         Exchange Act is recorded, processed, summarized and reported, within
         required time periods. Our Chief Executive Officer and Principal
         Financial Officer have evaluated the effectiveness of our disclosure
         controls and procedures as of a date within 90 days before the filing
         of this annual report (the "Evaluation Date"), and have concluded that,
         as of the Evaluation Date, our disclosure controls and procedures are
         effective in providing them with material information relating to the
         Company known to others within the Company which is required to be
         included in our periodic reports filed under the Exchange Act.

 (b)     There have been no significant changes in the Company's internal
         controls or in other factors which could significantly affect internal
         controls subsequent to the Evaluation Date.
