ITEM 1 DESCRIPTION OF BUSINESS (CONTINUED)

      (d)   NARRATIVE DESCRIPTION OF BUSINESS

            The Company is a financial holding company as defined under the Bank
            Holding Company Act of 1956, as amended (the "BHC Act"). The BHC Act
            regulates acquisitions by the Company of voting shares or assets of
            any bank or other company. The Company is subject to the reporting
            requirements of, and examination and regulation by, the Board of
            Governors of the Federal Reserve System, as well as reporting
            requirements under the Securities and Exchange Commission Act of
            1934.

            The Banks' are located in northeastern, eastern, southeastern and
            south central Ohio and are engaged in the business of commercial and
            retail banking in Belmont, Harrison, Tuscarawas, Carroll, Athens,
            Hocking, and Fairfield counties and the surrounding localities. The
            Banks provide a broad range of banking and financial services, which
            include accepting demand, savings and time deposits and granting
            commercial, real estate and consumer loans. CITIZENS conducts its
            business through its main office in Martins Ferry, Ohio and nine
            branches located in Bridgeport, Colerain, Dellroy, Dover, Jewett,
            New Philadelphia, St. Clairsville, Sherrodsville, and Strasburg,
            Ohio. CITIZENS offers full service brokerage service with securities
            provided through UVEST(R) member NASD/SIPC. COMMUNITY conducts its
            business through its seven offices in Amesville, Glouster,
            Lancaster, and Nelsonsville, Ohio.

            The markets in which the Banks' operate continue to be highly
            competitive. CITIZENS competes for loans and deposits with other
            retail commercial banks, savings and loan associations, finance
            companies, credit unions and other types of financial institutions
            within the Mid-Ohio valley geographic area along the eastern border
            of Ohio, extending into the northern panhandle of West Virginia and
            the Tuscarawas and Carroll County geographic areas of northeastern
            Ohio. COMMUNITY also encounters similar competition for loans and
            deposits throughout the Athens, Hocking, and Fairfield County
            geographic areas of central and southeastern Ohio.

            On November 12, 1999, the Graham-Leach-Bliley Act of 1999 ("GLB
            Act") was enacted, which is intended to modernize the financial
            services industry. The GLB Act sweeps away large parts of a
            regulatory framework that had its origins in the Depression Era of
            the 1930s. Effective March 11, 2000, new opportunities became
            available for banks, other depository institutions, insurance
            companies and securities firms to enter into combinations that
            permit a single financial service 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, which will have as its umbrella regulator
            the Federal Reserve Board. The functional regulation of the
            financial holding company's separately regulated subsidiaries will
            be conducted by their primary functional regulator. The GLB Act
            makes satisfactory or above Community Reinvestment Act compliance
            for insured depository institutions and their financial holding
            companies necessary 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 Banks are also subject to certain state laws that deal with the
            use and distribution of non-public personal information.

            The Company's two subsidiary banks are subject to regulation by the
            Ohio Division of Financial Institutions ("ODFI") and the Federal
            Deposit Insurance Corporation ("FDIC"). The regulations and
            restrictions affecting the Banks

            pertain to, among other things, allowable loans, guidelines for
            allowance for loan losses, accountability for fair and accurate
            disclosures to customers and regulatory agencies, permissible
            investments and limitations of risk and regulation of capital
            requirements for safe and sound operation of the financial
            institution.

            The Banks have no single customer or related group of customers
            whose banking activities, whether through deposits or lending, would
            have a material impact on the continued earnings capabilities if
            those activities were removed.


                                                                               4

II    INVESTMENT PORTFOLIO

A Securities available for sale at year-end 2002 increased $18,825,000, or 16.5%
over 2001, while securities held to maturity increased $2,547,000, or 24.5%. In
our planning process, Management's projection for 2002 was for a steady to
slightly rising interest rate environment. For the first half of 2002,
Management maintained an average of $13.8 million in fed funds sold. As the
economy continued to weaken, and threat of war surfaced, Management's, posture
on interest rates for the remainder of 2002 and heading into 2003 changed from
one that interest rates may rise to a position that rates will go basically
unchanged for the next twelve months. Therefore, by December 31, 2002,
Management invested the Company's excess liquidity in investment securities and
in loans. During 2002 the Company recognized gains of $320,485 on the sale of
investment securities. Management's strategy in 2002, took into consideration
the relative volatility in the bond market. At times during the year Management
realized there were opportunities to sell certain bonds in the portfolio when
overall interest rates were depressed. Security gains are non recurring income
and depending on future interest rate scenarios, the gains on the sale of
investment securities may negatively impact the yield on the investment
portfolio in future periods, and also negatively impact the Company's net
interest margin

The following table sets forth the carrying amount of securities at December 31,
2002, 2001 and 2000:

                  (1) Loans considered impaired under the provisions of SFAS No.
                  114 and interest recognized on a cash received basis were not
                  considered material during any of the periods presented.

                  The additional amount of interest income that would have been
                  recorded on nonaccrual loans, had they been current, totaled
                  $43,047 for the year-ended December 31, 2002.

                  Interest income is not reported when full loan repayment is
                  doubtful, typically when the loan is impaired or payments are
                  past due over 90 days. Payments received on such loans are
                  reported as principal reductions.

                  A loan is impaired when full payment under the loan terms is
                  not expected. Impairment is evaluated in total for
                  smaller-balance loans of similar nature such as residential
                  mortgage, consumer, and credit card loans, and on an
                  individual loan basis for other loans. If a loan is impaired,
                  a portion of the allowance is allocated so that the loan is
                  reported, net, at the present value of estimated future cash
                  flows using the loan's existing rate or at the fair value of
                  collateral if repayment is expected solely from the
                  collateral.

            1.    POTENTIAL PROBLEM LOANS

                  The Company had no potential problem loans as of December 31,
                  2002 which have not been disclosed in Table C 1., but where
                  known information about possible credit problems of borrowers
                  causes management to have serious doubts as to the ability of
                  such borrowers to comply with the present loan repayment terms

ITEM 12 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Regulations of the Securities and Exchange Commission require the
      disclosure of any related party transactions with members of the
      Compensation Committee. During the past year, certain directors and
      officers, including members of the Compensation Committee, and one or more
      of their associates may have been customers of and had business
      transactions with one or more of the bank subsidiaries of United Bancorp,
      Inc. All loans included in such transactions were made in the ordinary
      course of business and on substantially the same terms, including interest
      rates and collateral, as those prevailing at the same time for comparable
      transactions with other persons, and did not involve more than normal risk
      of collectability or present other unfavorable features. It is expected
      that similar transactions will occur in the future. In addition, The
      Citizens Savings Bank, a wholly-owned subsidiary of the Corporation,
      pursuant to the terms of a lease entered into on April 1, 1998, paid
      Riesbeck Food Markets, Inc. $25,128 in 2002, and over the five-year term
      of the lease, payments will total $130,000 as lease payments for space
      used in an in-store banking location at St. Clairsville, Ohio. Mr.
      Riesbeck, Chairman of the Compensation Committee, is an officer, director
      and shareholder of Riesbeck Food Markets, Inc. Management believes the
      lease between Riesbeck Food Markets, Inc. and the Corporation was made on
      an arms-length basis. Management employed a third party consulting firm
      that specializes in grocery store banking facilities to establish the
      terms of the lease.

ITEM 13 CONTROLS AND PROCEDURES

      Within the 90-day period prior to the filing date of this report, 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
      Rules13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934).
      Based on their evaluation, our Chief Executive Officer and Chief Financial
      Officer have concluded that the Company's disclosure controls and
      procedures are, to the best of their knowledge, effective to ensure that
      information required to be disclosed, processed, summarized and reported
      within the time periods specified in Securities and Exchange Commission
      rules and forms. Subsequent to the date of their evaluation, our Chief
      Executive Officer and Chief Financial Officer have concluded that there
      were no significant changes in United Bancorp's internal controls or in
      other factors that could significantly affect its internal control,
      including any corrective actions with regard to significant deficiencies
      and material weaknesses.

                             entitled to a lump sum severance benefit in the
                             event of their involuntary termination of
                             employment (other than for cause) following a
                             "change in control" of the Corporation. A change in
                             control is defined to include the acquisition of
                             the Corporation and certain other changes in the
                             voting control of the Corporation. In the event of
                             a change in control and the involuntary termination
                             of employment, the agreements provide that Mr.
                             James W. Everson will receive 2.99 times his annual
                             compensation, Mr. Hooker will receive 2.0 times his

                             Greenwood will receive 1.0 time his annual
                             compensation and Mr. Assenza will receive 1.0 times
                             his annual compensation in a lump sum cash payment.
                             Each agreement has a term of one year and is
                             automatically extended for one additional year
                             unless, not later than June 30 of the preceding
                             year, the Corporation gives notice of termination
                             of the agreement. The right of the Corporation to
                             terminate the employment of Mr. James W. Everson,
                             Mr. Hooker. Mr. Scott A. Everson, Mr. Greenwood and
                             or Mr. Assenza prior to a change in control is
                             unaffected by these agreements. In the event a
                             change in control had occurred on January 1, 2003,
                             and Mr. James W. Everson's, Mr. Hooker's, Mr Scott
                             A. Everson's, Mr. Greenwood's or Mr. Assenza'a
                             employment had been involuntarily terminated on
                             such date (other than for cause), Mr. James W.
                             Everson, Mr. Hooker, Mr. Scott A. Everson, Mr.
                             Greenwood and Mr. Assenza would have been entitled
                             to receive lump sum severance benefits of $752,448,

                             respectively. In the event a potential change in
                             control is announced, the agreements obligate Mr.
                             James W. Everson, Mr. Hooker, Mr Scott A. Everson,
                             Mr. Greenwood and Mr. Assenza to remain in the

                             year following the change in control of the
                             Corporation. The Change in control contracts can be
                             found in Exhibits 10.1 through 10.7.
