                           PROSPECTUS/PROXY STATEMENT

                                  INTRODUCTION

THE COMPANY
        
        This Prospectus/Proxy Statement and the accompanying proxy card are
being furnished to the shareholders of the Company in connection with the
solicitation of proxies by the Board of Directors of the Company for the Oak
Hill Special Meeting to be held at _____ _.m., local time, on ________,
_____________ __, 1997, at the Ohio State University Extension South District
Office, 17 Standpipe Road, Jackson, Ohio, and any adjournments or postponements
thereof, to adopt the Merger Agreement, pursuant to which 792,625 shares of Oak
Hill Common Stock, as such number may be adjusted downward in accordance with
the terms of the Merger Agreement, will be issued to the shareholders of Unity
Savings Bank ("Unity"). This Prospectus/Proxy Statement and accompanying proxy
card are first being mailed to the shareholders of the Company on or about
________ __, 1997.

        This Prospectus/Proxy Statement also constitutes a prospectus of the
Company with respect to the issuance of 792,625 shares of Oak Hill Common Stock
pursuant to the Merger Agreement (as such number of shares may be adjusted
downward in accordance with the terms of the Merger Agreement) in order to
effect the proposed acquisition of Unity by the Company.

        The shares represented by the accompanying proxy card will be voted as
directed if the proxy is properly signed and received by the Company prior to
the Oak Hill Special Meeting. If no directions are made to the contrary on a
duly executed and returned proxy, then the proxy will be voted FOR the adoption
of the Merger Agreement, pursuant to which 792,625 shares of Oak Hill Common
Stock, as such number of shares may be adjusted downward in accordance with the
terms of the Merger Agreement, will be issued to the shareholders of Unity. The
proxy also grants discretionary authority to vote on other matters which may
arise at the Oak Hill Special Meeting. While management is presently unaware of
any such matters, the person or persons designated to vote the shares will cast
votes according to their best judgment if any such matters properly come before
the Oak Hill Special Meeting. Any shareholder giving the enclosed proxy has the
power to revoke it at any time prior to the Oak Hill Special Meeting by filing
with the Secretary of the Company a written notice of revocation or a subsequent
proxy relating to the same shares, or by attending the Oak Hill Special Meeting
and voting in person. Shareholders who attend the meeting may vote in person and
their proxies will not then be used.

        A majority of the outstanding shares of Oak Hill Common Stock,
represented in person or by proxy, will constitute a quorum at the meeting.
Abstentions and broker non-votes will be counted for purposes of determining the
presence of a quorum at the Oak Hill Special Meeting. The affirmative vote of
the holders of a majority of the shares of Oak Hill Common Stock present in
person or by proxy and entitled to vote (assuming the presence of a quorum) at
the Oak Hill Special Meeting is required to approve the issuance of shares of
Oak Hill Common Stock pursuant to the Merger Agreement. Because approval of the
Merger requires the affirmative vote of a particular percentage of the shares of
Oak Hill Common Stock voting, an abstention or a broker non-vote will have the
same effect as a vote against the Merger.

RECORD DATE; SHARES ENTITLED TO VOTE

        Only the Company's shareholders of record at the close of business on
July ___, 1997 (the "Oak Hill Record Date"), will be entitled to vote at the Oak
Hill Special Meeting. At that date, the Company had 2,873,500 shares of Oak Hill
Common Stock outstanding and entitled to vote on all matters requiring a vote of
the shareholders. These shares were held by approximately ____ holders of
record. Each share of Oak Hill Common Stock entitles the holder to one vote,
exercisable in person or by properly executed proxy, on each matter that comes
before the shareholders at the Oak Hill Special Meeting.

        The Company will bear the cost of the solicitation of proxies, including
the charges and expenses of brokerage firms and others, if any, for forwarding
solicitation material to beneficial owners of stock. Representatives of the
Company may solicit proxies by mail, telegram, telephone, or personal interview.

UNITY

        This Prospectus/Proxy Statement is being furnished to the shareholders
of Unity in connection with the solicitation of proxies by the Board of

<PAGE>   14
and any adjournments or postponements thereof, to adopt the Merger Agreement,
pursuant to which Unity will be merged with and into the Bank and the
shareholders of Unity will become shareholders of the Company. This
Prospectus/Proxy Statement and accompanying proxy card will be first sent or
given to the shareholders of Unity on or about July __, 1997.

        The shares represented by the accompanying proxy card will be voted as
directed if the proxy is properly signed, dated and received by Unity prior to
the Unity Special Meeting. If no directions are made to the contrary on a duly
executed and returned proxy, then the proxy will be voted FOR the adoption of
the Merger Agreement, pursuant to which each Unity Common Share will be
exchanged for 8.5 shares of Oak Hill Common Stock, as such number may be
adjusted downward pursuant to the Merger Agreement. The proxy also grants
discretionary authority to vote on other matters which may arise at the Unity
Special Meeting. While management is presently unaware of any such matters, the
person or persons designated to vote the shares will cast votes according to
their best judgment if any such matters properly come before the Unity Special
Meeting. Any Unity shareholder giving the enclosed proxy has the power to revoke
it at any time prior to the Unity Special Meeting by a later dated proxy
received by Unity or by giving notice of revocation to Unity in writing or in
open meeting. Shareholders who attend the meeting may revoke their proxies and
vote in person.

        The Unity Common Shares represented in person or by proxy at the Unity
Special Meeting will constitute a quorum at the meeting. The affirmative vote of
the holders of two-thirds of the Unity Common Shares outstanding on the record
date for the Unity Special Meeting is required to adopt the Merger Agreement.

"initial period") which is contingent on the consummation of the Merger. He will
be employed as a Senior Vice President and will be appointed to the Boards of
Directors of the Company and the Bank. His base salary will be $100,000 and he
will be entitled to participate in the Company's employee benefit plans. Upon
the consummation of the Merger, he will receive options under the Company's 1995
Stock Option Plan as specified in his employment agreement. The employment
agreement also provides that if he is terminated without cause during the
initial period, the Company will pay to him a sum equal to the remaining unpaid
salary for the initial period, in equal monthly installments which commence on
the date of his termination and continue until the termination of the initial
period. See "CERTAIN RELATED TRANSACTIONS."

        Executive salary continuation agreements were entered into between Unity
and George Knox and Unity and D. Bruce Knox in 1994. The salary continuation
agreements contain provisions which vest the benefits thereunder upon a change
in control of the ownership of Unity. The salary continuation agreement entered
into by George Knox and Unity provides for the institution of the retirement
benefits contemplated by the agreement, effective June 30, 1997. Consummation of
the Merger requires that the salary continuation agreement entered into by D.
Bruce Knox be terminated and all claims thereunder be released as consideration
for a payment by Unity to Mr. Knox of $206,000. See "CERTAIN RELATED
TRANSACTIONS."

REGULATORY REQUIREMENTS

        The Company has filed a request to the Board of Governors of the Federal
Reserve System (together with the Federal Reserve Bank of Cleveland, the
"Federal Reserve Board") for an exemption from the Federal Reserve Board's
general requirement of an application for bank holding company mergers. The
Company expects that this waiver will be granted and that only a 30-day prior
notice to the Federal Reserve Bank of Cleveland will be required. The Merger
must be approved by the Federal Deposit Insurance Corporation (the "FDIC") and
the Ohio Superintendent of Financial 


                                      -7-

Institutions. The notices and applications required to be filed with these
agencies were submitted or filed on June 30, 1997. See "THE MERGER - Regulatory
Approvals."

RISK FACTORS

        The acquisition of Oak Hill Common Stock by Unity shareholders in the
Merger involves certain risks, including, but not limited to the following: (i)
management of growth; (ii) rising interest rates affecting the Company's
cumulative interest rate gap; (iii) share ownership of management; (iv) credit
risk and economic conditions; (v) intense competition; and (vi) dependence on
management.

        Shareholders of the Company should consider Unity's financial
performance and the integration of Unity into the Company in deciding whether or
not to approve the Merger.

        For a fuller discussion of these and other risks affecting the Company,
its business, and the Merger, see "RISK FACTORS."

        The ability of the Company to pay cash dividends to shareholders is
limited by its ability to receive dividends from its subsidiary. As discussed in
Note K of Notes to the Consolidated Financial Statements, the State of Ohio
places certain limitations on the payment of dividends by Ohio state-chartered
banks. The Company paid a split-adjusted cash dividend of $.064 per share during
the six-month period ended June 30, 1995. Commencing with the fourth quarter of
1995, the Company has declared the following quarterly cash dividends:

operations, investment opportunities, capital requirements, and regulatory
limitations.

</TABLE>

                                  RISK FACTORS

        The Company desires to take advantage of the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995 (the "Reform Act"). Many of
the important factors discussed below have been discussed in the Company's prior
filings with the Commission. In addition to the other information in this
Prospectus/Proxy Statement, shareholders of the Company and the shareholders of
Unity should carefully consider the following factors in evaluating the Company
and its business before making a decision regarding the vote on the Merger. The
following important factors, among others, in some cases have affected, and in
the future could affect, the Company's actual results and could cause the
Company's actual consolidated results of operations to differ materially from
those expressed in any forward-looking statements made by, or on behalf of, the
Company.

        Growth Strategy. The Company has pursued and continues to pursue a
strategy of growth. The success of the Company's growth strategy will depend
largely upon its ability to manage its credit risk and control its costs while
providing competitive products and services. This growth strategy may present
special risks, such as the risk that the Company will not efficiently handle
growth with its present operations, the risk of dilution of book value and
earnings per share as a result of an acquisition, the risk that earnings will be
adversely affected by the start-up costs associated with establishing new
products and services, the risk that the Company will not be able to attract and
retain qualified personnel needed for expanded operations, and the risk that its
internal monitoring and control systems may prove inadequate.

        Potential Impact of Changes In Interest Rates. The Company's results of
operations are dependent to a large degree on net interest income, the
difference between interest income from loans and investments and interest
expense on deposits and borrowings. One common measurement of interest rate
risk, known as the interest rate gap, is the difference between interest-earning
assets and interest-bearing liabilities repricing or maturing within various
time frames, expressed as a percentage of total assets. At December 31, 1996,
the Company had a negative cumulative interest rate gap of 1.56% for one year.
As a result of this cumulative negative interest rate gap position, the rate of
increase in the costs associated with the Company's deposits could be expected
to increase more rapidly than the rate of increase in the Company's income from
loans and investments in a period of rising interest rates. Consequently, a
significant increase in market rates of interest could adversely affect net
interest income.

        Control by Management; Anti-Takeover Provisions. Evan E. Davis, John D.
Kidd, and D. Bruce Knox (the "Principal Shareholders") will own in the aggregate
approximately 57% of the outstanding shares of the Oak Hill Common Stock after
the Merger. Accordingly, because holders of Oak Hill Common Stock are not
permitted to vote their shares cumulatively in the election of directors, the
Principal Shareholders will retain the power to elect the entire Board of
Directors of the Company and to determine the outcome of any other matters
submitted to the Company's shareholders for approval. In addition to Ohio and
federal laws and regulations governing changes in control of insured depository
institutions, the Company's Articles of Incorporation and Code of Regulations
contain certain provisions which may delay or make more difficult an acquisition
of control of the Company. For example, the Company's Articles of Incorporation
do not exempt the Company from the provisions of Ohio's "control share
acquisition" and "merger moratorium" statutes. Assuming that the Principal
Shareholders continue to retain at least a majority of the outstanding voting
shares of the Company, such ownership position could be expected to deter any
prospective acquiror from seeking to acquire ownership or control of the
Company, and the Principal Shareholders would be able to defeat any acquisition
proposal that requires approval of the Company's shareholders. In addition, the
Principal Shareholders may make a private sale of shares of Oak Hill Common
Stock which they own, including to a person seeking to acquire ownership or
control of the Company. The Company has 3,000,000 shares of authorized but
unissued preferred stock, par value $ .01 per share, which may be issued in the
future with such rights, privileges and preferences as are determined by the
Board of Directors of the Company These shares may have the effect of making
more difficult or discouraging any acquisition of the Company which is
determined to be undesirable by the Board of Directors.


                                      -10-
<PAGE>   20
        Credit Risk; Exposure To Economic Conditions in Jackson, Scioto and Ross
Counties, Ohio. A significant risk facing lenders generally is credit risk, that
is, the risk of losing principal and accrued interest if borrowers fail to
perform according to the terms of the loan agreements. The Bank's concentration
of loans in Jackson, Scioto, and Ross Counties, Ohio, exposes it to risks
resulting from changes in the local economies. Per capita income in Jackson,
Scioto and Ross Counties is typically less than the statewide average, while
unemployment in the same three counties is typically higher than the statewide
unemployment level. While the Bank's market area for loans extends throughout
most of southeastern Ohio and Butler County, Pickaway County and Warren County,
Ohio, its lending operations are concentrated in Jackson, Scioto, and Ross
Counties, Ohio.

        Competition. Banking institutions operate in a highly competitive
environment. The Company competes with other commercial banks, credit unions,
savings institutions, finance companies, mortgage companies, mutual funds, and
other financial institutions, many of which have substantially greater financial
resources than the Company. Certain of these competitors offer products and
services that are not offered by the Company and certain competitors are not
subject to the same extensive laws and regulations as the Company. Additionally,
consolidation of the financial services industry in Ohio and in the Midwest in
recent years has increased the level of competition. Recent and proposed
regulatory changes may further intensify competition in the Company's market
area.

        Shares Eligible for Future Sale. The market price of the Oak Hill Common
Stock could be adversely affected by the sale of additional shares of Oak Hill
Common Stock owned by the Company's current shareholders. The Principal
Shareholders are permitted to sell certain limited amounts of Oak Hill Common
Stock without registration, pursuant to Rule 144 under the Securities Act.

        Dependence on Management. The Company's success depends to a great
extent on its senior management, including its Chairman, Evan E., Davis,
President, John D. Kidd, Executive Vice President, Richard P. LeGrand and H. Tim
Bichsel, Secretary and Treasurer. The loss of their individual services could
have a material adverse impact on the Company's financial stability and its
operations. In addition, the Company's future performance depends on its ability
to attract and retain key personnel and skilled employees, particularly at the
senior management level. The Company's financial stability and its operations
could be adversely affected if, for any reason, one or more key executive
officers ceased to be active in the Company's management. The Company does not
own or currently plan to acquire "key man" life insurance on the lives of any of
its key employees.

        Unity's Financial Performance and Integration. As a savings bank, Unity
is subject to many of the same risks as the Company, including interest rate
risk, credit risk and competition. Although Unity has been profitable to date,
there is no guarantee that Unity will continue to be profitable and that the
integration of Unity and the Company will be successful.

                                   THE MERGER

BACKGROUND OF THE MERGER

        The Company, an Ohio corporation, is a bank holding company that engages
directly in the business of commercial banking and other permissible activities
closely related to banking, through its wholly owned subsidiary, the Bank. The
Company and the Bank have twelve banking locations in Southeastern Ohio. The
Company faces strong competition from other banking institutions, including
local and regional banks and bank holding companies, as well as some of the
largest banking organizations in the United States. As of March 31, 1997, the
Company had approximately $262.8 million in total assets.

        Unity is an Ohio savings bank with four banking locations in
Southeastern Ohio. As of March 31, 1997, Unity had approximately $65.1 million
in total assets.

        The Company and Unity believe that the combination of Unity with the
Bank will enable the Company to reach a wider customer base and thus strengthen
its position in the banking industry in Southeastern Ohio.

        The terms and conditions of the Merger were determined in arms' length
negotiations between the management teams and Boards of Directors of the Company
and Unity with advice from their respective financial advisors and lawyers,
after evaluations of the current financial condition, earnings potential and
market position of the Company and Unity, as well as the business prospects of
the combined company.

THE COMPANY'S REASONS FOR THE MERGER; RECOMMENDATION OF THE COMPANY'S BOARD OF 
DIRECTORS

        The management of the Company believes that the Merger offers
significant benefits to the Company. In approving the Merger and the Merger
Agreement, the Company's Board considered a number of factors. The Company's
Board did not assign any relative or specific weight to any of the factors. The
factors considered included:

        1. Financial Terms of the Merger. The Company's Board of Directors
evaluated the information it received from Trident Financial Corporation,
indicating that the terms of the transaction were fair to the Company's
shareholders.


                                      -11-
<PAGE>   21
        2. Certain Financial and Other Information. The financial and other
information concerning the Company and Unity considered by the Company's Board
included, but was not limited to, information with regard to recent stock
performance, valuation analysis, pro forma analysis, and comparative financial
and operating performance.

        3. Economic and Competitive Environment. The Company's Board took into
account the current and prospective economic environment facing the financial
services industry generally, and the respective capacities of the Company and
Unity to compete effectively given the rapid changes in the industry.

        4. Regulatory Approvals. The Company's Board evaluated the likelihood of
obtaining the regulatory approvals that would be required with respect to the
Merger.

        Based upon the above analysis, the Company's Board of Directors
concluded that the Merger was favorable to its shareholders and would allow the
Company to enhance its ability to meet the financial needs of its customers. The
Company also believes the combination of the Bank and Unity will solidify the
Company's presence in the financial services industry in Southeastern Ohio. For
the reasons described above, the Company's Board of Directors at its meeting
held on March 11, 1997 unanimously determined that the Merger and the Merger
Agreement are advisable and fair and in the best interests of the Company and
its shareholders and approved the Merger and the Merger Agreement and
recommended that holders of Oak Hill Common Stock adopt the Merger Agreement.

UNITY'S REASONS FOR THE MERGER; RECOMMENDATION OF UNITY'S BOARD OF DIRECTORS

        Unity has been approached from time to time by other financial
institutions, including the Company, which have expressed an interest in
affiliating with Unity. When faced with such overtures, the Board has carefully
considered Unity's future prospects in view of prevailing and anticipated
regulatory, economic and competitive conditions to determine the course of
action that was in the best interests of its shareholders. In prior years, the
Board has determined, relative to the proposals of interested acquirors, that
the shareholders of Unity would best be served by Unity remaining independent.

        In January 1997 the Company again approached Unity to discuss a possible
affiliation. In once again considering the merits of a merger, the Board
considered the many changes that have affected the thrift industry recently as
regulatory matters continue to become increasingly complex and as technology
assumes an ever-increasing role in the delivery of financial products and
services. The Board also discussed the competitive challenges which Unity will
be likely to encounter in the future, as well as the lack of liquidity with
respect to Unity's Common Shares. The Board reached the conclusion that, at this
time, the shareholders and customers of Unity would be best served by
affiliating with a larger financial institution.

        Unity engaged McDonald & Company Securities, Inc. ("McDonald &
Company"), an investment banking firm experienced in financial institution
mergers and acquisitions, to advise the Board concerning a possible affiliation.
McDonald & Company performed an analysis of Unity relative to comparable
financial institutions and prepared an extensive comparable merger transaction
analysis to help the Board assess Unity's valuation in an acquisition context.
In conjunction with McDonald & Company, the Board compiled a list of other
financial institutions which had a presence in Southern Ohio as prospective
merger partners, without regard to whether such companies had previously
indicated an interest in acquiring Unity. The Board, with the assistance of
McDonald & Company, evaluated the different characteristics of the institutions
which had been identified to determine their suitability as merger partners. The
Board of Unity considered a number of factors, including, but not limited to,
the market performance of each company's stock, the characteristics of the
market served by the company, the products and services offered by the company
and the prospects for Unity's employees. After considering and weighing various
factors, the Board concluded that the Company was the most suitable acquiror and
decided to enter into negotiations with the Company.

        The Company has a strong record of profitability and growth. Since its
initial public offering price of $9.75 per share in October 1995, the Oak Hill
Common Stock has achieved a market value of $19.25 per share as of June 25,
1997. In conjunction with McDonald & Company, the Board evaluated the Company's
prospects for increased profitability and growth.

        The Merger presents an opportunity for the shareholders of Unity to
exchange their Unity Common Shares in a non-taxable transaction Oak Hill Common
Stock at a premium relative to Unity's book value per share. Shares of Oak Hill
Common Stock, which will total more than 3,000,000 after the Merger, are listed
on The Nasdaq National Market under the symbol "OAKF" and are beneficially owned
by approximately 1,400 shareholders. These characteristics indicate an
established market for Unity shareholders who want to sell all or part of their
stock after the Merger. Those shareholders who continue to hold their shares,
however, will realize a significant return on their investment while deferring
the tax consequences of that gain.

        The asset size of the Company is another important consideration to the
Board. The Company is large enough to support the staff and the technology
necessary to offer products and services that Unity does not offer. Commercial
banking, participation in the secondary market and automated teller machines are
just a few examples of the products and services that will be available to
Unity's customers as a result of the Merger. While its size enables the Company
to conduct these activities effectively and profitably, the Company is not too
large to be compatible with Unity. Like Unity, the Company has served the
financial service needs of small communities throughout Southern Ohio, and there
are many similarities between the business philosophy and customer-service
orientation of Unity and the Company.


                                      -12-

Moreover, because of its size, the Company can offer Unity's employees more
diverse opportunities for career advancement.

        Geographically, the Company and Unity fit well together. Jackson, Ohio
is the only market where Unity and the Company both have branches. The proximity
of the Company's headquarters to Unity's offices will facilitate the
communications, employee training and technological support which are necessary
to a smooth transition and to the successful expansion of products and services
in the Unity offices. In addition, a significant number of the Company's
shareholders are residents of Southern Ohio, which the Board believes will help
foster the community orientation that has been the hallmark of Unity's business.

        The Board recognized that these features would provide the foundation
for a combination that would benefit Unity's shareholders, its employees, its
customers and the communities it services. On April 28, 1997, at the conclusion
of arm's length negotiations between Unity and the Company, the Board of Unity
met to consider approval of the terms of the Merger Agreement. At that meeting,
representatives of McDonald & Company met with the Board to review the financial
components of the Merger and advised the Board that, in the opinion of McDonald
& Company as of that date, the Exchange Ratio was fair to the Unity shareholders
from a financial point of view.

        Based on all the foregoing, the directors of Unity concluded that the
terms of the Merger, as set forth in the Merger Agreement, were in the best
interests of Unity and its shareholders.

OPINION OF FINANCIAL ADVISOR FOR OAK HILL

        The Company retained Trident Financial Corporation ( "Trident" ) on
April 4, 1997 to act as the Company's financial advisor in connection with a
possible business transaction with Unity, including rendering its opinion to the
Company's Board of Directors as to the fairness to the Company, from a financial
point of view, of the Merger Consideration. As part of its engagement, Trident
performed a valuation analysis of Unity in an acquisition context. On April 15,
1997, Trident delivered its valuation report to the Company's Board of
Directors. In its report Trident reviewed the terms of the Merger, provided
market information with respect to thrift mergers and acquisitions, compared the
Company's offer to the valuation of Unity, and estimated the pro forma effect of
the Merger. In addition, Trident rendered its written opinion to the Company's
Board of Directors to the effect that, as of that date, the consideration to be
paid by the Company, pursuant to the Merger Agreement, was fair from a financial
point of view to its shareholders. The Merger Consideration was determined
pursuant to a negotiated process conducted by Unity and its advisors. Trident
did not advise the Company during the negotiation process.

        Trident delivered its updated written opinion to the Company's Board of
Directors as of the date of this Prospectus/Proxy Statement stating that, as of
such date, the consideration to be paid by the Company in the Merger is fair
from a financial point of view to its shareholders. Trident has consented to the
inclusion of such opinion and the related disclosure in this Prospectus/Proxy
Statement.

        TRIDENT'S OPINION IS DIRECTED TO THE BOARD OF DIRECTORS OF THE COMPANY
AND IS DIRECTED ONLY TO THE FAIRNESS TO THE COMPANY'S SHAREHOLDERS, FROM A
FINANCIAL POINT OF VIEW, OF THE MERGER CONSIDERATION TO BE PAID BY THE COMPANY
BASED ON CONDITIONS AS THEY EXISTED AND COULD BE EVALUATED AS OF THE DATE OF THE
OPINION. TRIDENT'S OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO ANY
SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE SPECIAL MEETING, NOR
DOES TRIDENT'S OPINION ADDRESS THE UNDERLYING BUSINESS DECISION TO EFFECT THE
MERGER. THIS SUMMARY OF TRIDENT'S OPINION IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION, WHICH IS ATTACHED TO THIS
PROSPECTUS/PROXY STATEMENT AS APPENDIX C. THE COMPANY'S SHAREHOLDERS ARE URGED
TO READ TRIDENT'S OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF THE ASSUMPTIONS
MADE AND MATTERS CONSIDERED AND THE LIMITS ON THE REVIEW UNDERTAKEN IN RENDERING
SUCH OPINION.

        In connection with rendering its opinion, Trident reviewed and analyzed,
among other things, the following: (i) the Merger Agreement; (ii) this
Prospectus/Proxy Statement; (iii) certain publicly available information
concerning Unity, including the audited financial statements of Unity for each
of the years in the three-year period ended December 31, 1996, and unaudited
financial statements for the three months ended March 31, 1997; (iv) certain
publicly available information concerning the Company, including the audited
financial statements of the Company for each of the years in the three-year
period ended December 31, 1996, and unaudited financial statements for the three
months ended March 31, 1997; (v) certain other internal information, primarily
financial in nature, concerning the business and operations of Unity and the
Company furnished to Trident by Unity and the Company for purposes of Trident's
analysis; (vi) certain information with respect to the limited trading market
for Unity Common Stock; (vii) certain information with respect to the pricing
and trading of Oak Hill Common Stock; (viii) certain publicly available
information with respect to other companies that Trident believed to be
comparable to Unity and the Company and the trading markets for such other
companies' securities; and (ix) certain publicly available information
concerning the nature and terms of other transactions that Trident considered
relevant. Trident had discussions with certain officers and employees of Unity
and the Company to review the foregoing, as well as other matters which it
believed relevant to its inquiry, such as: (i) the current business operations,
financial condition, and future prospects of the Company and Unity; (ii) the
results of Trident's due diligence examination of Unity; and (iii) the expected
cost savings and revenue enhancements resulting from the Merger. Trident also
took into account its assessment of general economic, market, financial and
regulatory 


                                      -13-
<PAGE>   23
conditions and trends, as well as its knowledge of the financial institutions
industry, its experience in connection with similar transactions, and its
knowledge of securities valuation generally.

        In its review and analysis, and in arriving at its opinion, Trident
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided to it, or that was publicly available, and did
not attempt independently to verify any such information. Trident did not
conduct a physical inspection of the properties or facilities of the Company or
Unity, nor did it make or obtain any independent valuations or appraisals of any
of such properties or facilities.

        The following is a summary of the material valuation, financial and
comparative analyses performed by Trident in arriving at its fairness opinion.
The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial or summary description. Trident believes that
its analyses and the summary set forth below must be considered as a whole and
that selecting portions of its analyses without considering all of the analyses,
or the summary without considering all factors and analyses, would create an
incomplete view of the processes underlying the analyses set forth in Trident's
report and its opinion. Therefore, the ranges of valuations resulting from any
single analysis described below should not be taken to be Trident's view of the
actual value of Unity or the combined company. In performing its analyses,
Trident made numerous assumptions with respect to industry performance, general
business and economic conditions and other matters, many of which are beyond the
control of the Company or Unity. The results of the specific analyses performed
by Trident may differ from the Company's or Unity's actual values or actual
future results as a result of changing economic conditions, changes in company
strategy and policies, as well as a number of other factors. Such individual
analyses were prepared to provide valuation guidance solely as part of Trident's
overall valuation analysis and the determination of the fairness of the
consideration to be paid by the Company's shareholders, and were provided to the
Company's Board of Directors in connection with the delivery of Trident's
opinion. The analyses do not purport to be appraisals or to reflect the prices
at which a company might actually be sold or the prices at which any securities
may trade at the present time or at any time in the future. In addition, as
described above, Trident's opinion and report to the Company's Board of
Directors were among the many factors taken into consideration by the Company's
Board of Directors in making its determination to approve the Merger Agreement.

        Financial Analysis of Unity. Trident examined Unity's financial
performance for the period December 31, 1992 through December 31, 1996 by
analyzing the composition of its balance sheet, adjusting and normalizing its
earnings, and calculating a variety of operating and financial ratios for Unity.

        Peer Group Analysis. Trident evaluated Unity's strengths and weaknesses
by comparing its financial performance to that of the following groups of
state-chartered savings banks: (i) all United States institutions; (ii) all
institutions in the Midwest; (iii) all Ohio institutions; (iv) all United States
institutions with total assets between $50 million and $100 million; and (v)
Ohio institutions with total assets between $50 million and $100 million (the
"Aggregates"). This analysis compared a number of Unity's historical financial
ratios at September 30, 1996 to those of the Aggregates, including but not
limited to: (i) the balance sheet composition as a percentage of total assets;
(ii) the loan portfolio as a percentage of total assets; (iii) the investment
portfolio as a percentage of total assets; and (iv) asset quality. Trident also
compared Unity's growth rates between December 31, 1993 and September 30, 1996,
its yields on assets and costs of liabilities and its income and expense data
for 1995 and the nine months ended September 30, 1996 to those of the
Aggregates.

        Valuation of Unity. Trident estimated the fair market value of Unity in
an acquisition context using three different approaches to value: the asset
approach, the income approach and the market approach.

        The asset approach considers the market value of a company's assets and
liabilities, as well as any intangible value the company may have. Trident
estimated Unity's net asset value by adjusting the carrying value of its assets
and liabilities to reflect current market values. In addition, the net asset
value of Unity was adjusted downward based on an estimate of transaction and
other costs. Based on those adjustments, Trident estimated Unity's fully diluted
net asset value to be approximately $6.7 million or $71.82 per share. After
determining Unity's net asset value, Trident added an intangible premium to
reflect the estimated value of its customer relationships. According to the
asset approach, the total value of Unity is the sum of its net asset value and
its intangible value. Based on a branch purchase methodology and intangible (
core deposit ) premiums observed in the market for thrift acquisitions, as well
as Trident's knowledge of Unity, Trident applied premiums equal to 6.0% and
11.0% of core deposits to Unity's estimated fully diluted net asset value. Using
the asset approach, Trident established a reference range of $99.50 to $123.00
per share for Unity Common Stock.

        Trident also used an income approach in its valuation of Unity by
capitalizing its previous twelve months earnings (adjusted to exclude
non-recurring income and expense items) plus merger cost savings of 25% to 50%
as a result of an acquisition (the "Normalized Earnings"). The Normalized
Earnings were capitalized at rates of 8% to 14%. The capitalization rates chosen
were estimates of the required rates of return for holders or prospective
holders of shares of financial institutions similar to Unity, based on a number
of factors including prevailing interest rates, the pricing ratios of publicly
traded financial institutions, the financial condition and operating results of
Unity, as well as Trident's general knowledge of valuation, the securities
markets, and acquisition values in other mergers of financial institutions.
Trident adjusted the resulting value to reflect certain merger-related expenses.
Using the income approach, Trident established a reference range of $72.00 to
$109.00 per share for Unity Common Stock.


                                      -14-
<PAGE>   24
        In the market approach, Trident analyzed certain median pricing ratios
(e.g., price to book value, price to tangible book value, price to reported
earnings, price to assets, and the premium paid over tangible book value as a
percentage of core deposits) resulting from selected completed thrift merger
transactions, as well as recently announced pending transactions. In applying
the market approach, Trident considered the pricing ratios for the following
groups of thrift merger transactions: (i) all pending thrift merger transactions
(40 transactions); (ii) all pending thrift mergers announced during the 90 days
prior to April 1, 1997 (the date of the market data) (22 transactions); (iii)
all pending thrift mergers of Midwestern thrifts (13 transactions); (iv) all
pending thrift mergers in which the aggregate consideration was between $5
million and $15 million (6 transactions); (v) all pending thrift mergers in
which the target thrift had assets between $30 million and $100 million (9
transactions); (vi) all pending thrift mergers in which the target thrift had a
return on assets between 0.75% and 1.00% (8 transactions); (vii) all pending
thrift mergers in which the target thrift had a return on equity between 5.5%
and 9.5% (7 transactions); (viii) all pending thrift mergers in which the target
thrift had a tangible equity ratio between 10% and 13% of assets (7
transactions); and (ix) pending thrift mergers in which the target thrift had a
ratio of non-performing assets to assets between zero and 0.5% (15
transactions). Trident also considered the pricing ratios for ten pending or
completed thrift merger transactions in which the target thrift was of similar
size and capital structure as Unity, and in which the target thrift had similar
profitability and asset quality. Trident then compared a number of financial
ratios for Unity to those of the target thrift institutions.

        Based on Unity's financial condition and results of operations, as well
as other factors relative to the groups of thrift mergers noted above, Trident
selected ranges of pricing ratios to apply to Unity. Trident chose price to book
value ratios of 135% to 160%, resulting in per share values of $107.00 to
$126.75; price to tangible book value ratios of 135% to 160%, resulting in per
share values of $106.75 to $126.50; price to earnings multiples of 18 to 26
times earnings, resulting in per share values of $97.00 to $140.25; price to
assets ratios of 16% to 20%, resulting in per share values of $111.50 to
$139.50; and premiums over tangible book value as a percentage of core deposits
of 6% to 11%, resulting in per share values of $107.00 to $130.25. Based on
these derived ranges of value, Trident established a reference range of $105.00
to $130.00 per share using the market approach.

        After reviewing the results from the three approaches and considering
all relevant facts, Trident reconciled the acquisition values generated by each
approach and determined a final range of $107.00 to $123.00 per share as the
acquisition value of Unity. Trident did not apply specific weights to the three
individual approaches, but rather applied its judgment and experience in
determining the final range of value for Unity. On April 15, 1997, the Merger
Consideration ($121.13 per share) was within Trident's valuation range for
Unity.

        Contribution and Dilution Analysis. Trident presented a pro forma
combined balance sheet as of December 31, 1996 and a pro forma combined income
statement for the four quarters ended December 31, 1996 assuming a pooling of
interests based upon the Exchange Ratio. Trident analyzed the contribution of
each of the Company and Unity (on a fully diluted basis assuming projected cost
savings and revenue enhancements) to the pro forma combined company for, among
other things, ownership, equity, and earnings. Trident also compared the
earnings per share of Oak Hill Common Stock to the earnings per share of the
common stock of the combined company on a pro forma basis. Based on such
analysis and assuming certain projected cost savings and revenue enhancements,
the proposed transaction would be slightly accretive to the Company's book value
and earnings per share.

        Trident, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwriting, and valuations for corporate
and other purposes. Trident has extensive experience in the valuation of
financial institutions. The Company's Board of Directors selected Trident to
render a fairness opinion because Trident is a nationally recognized investment
banking firm specializing in financial institutions, with substantial experience
in transactions similar to the Merger. Trident is not affiliated with either the
Company or Unity.

        For its services, the Company paid Trident a retainer of $5,000 and a
fee of $10,000 upon delivery of its preliminary fairness opinion. A remaining
balance of $5,000 is due upon delivery of the final fairness opinion. The
Company has also agreed to reimburse Trident for its reasonable out-of-pocket
expenses and to indemnify Trident against certain liabilities, including certain
liabilities under federal securities laws.

OPINION OF FINANCIAL ADVISOR FOR UNITY

        Unity has retained McDonald & Company to render its opinion with respect
to the fairness, from a financial point of view, of the Exchange Ratio to the
holders of Unity Common Shares. McDonald & Company rendered its oral opinion to
the Unity Board of Directors on April 28, 1997, which it subsequently confirmed
in writing, that, as of the date of such opinion, the Exchange Ratio was fair,
from a financial point of view, to the holders of Unity Common Shares.

        THE FULL TEXT OF THE OPINION OF MCDONALD & COMPANY UPDATED AS OF THE
DATE OF THIS PROSPECTUS/PROXY STATEMENT, WHICH SETS FORTH CERTAIN ASSUMPTIONS
MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEWS UNDERTAKEN, IS ATTACHED
AS APPENDIX B TO THIS PROSPECTUS/PROXY STATEMENT, AND SHOULD BE READ IN ITS
ENTIRETY. THIS SUMMARY OF THE OPINION OF MCDONALD & COMPANY IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE OPINION. MCDONALD & COMPANY'S OPINION IS DIRECTED
TO THE UNITY BOARD OF DIRECTORS AND ADDRESSES ONLY THE EXCHANGE RATIO.


                                      -15-

        In arriving at its opinion, McDonald & Company reviewed, among other
things, the Merger Agreement together with exhibits and schedules thereto,
certain publicly available information relating to the business, financial
condition and operations of Unity and the Company, as well as certain other
non-public information, primarily financial in nature, furnished to it by Unity
and the Company relating to the respective businesses, earnings, assets and
prospects of Unity and the Company. McDonald & Company also held discussions
with members of senior management of Unity and the Company concerning their
respective businesses, assets, financial forecasts and prospects. McDonald &
Company also reviewed certain publicly available information concerning the
trading of, and the trading market for, Unity Common Shares and Oak Hill Common
Stock and certain publicly available information concerning comparable companies
and transactions, all as set forth in McDonald & Company's opinion.

        McDonald & Company was not engaged to and did not conduct a physical
inspection of any of the assets, properties, or facilities of either Unity or
the Company and was not engaged to and has not made, obtained or been furnished
with any independent evaluation or appraisal of any of such assets, properties,
or facilities or any of the liabilities of Unity or the Company. McDonald &
Company has assumed and relied, without independent investigation, upon the
accuracy and completeness of the financial and other information provided to it
or publicly available, has relied upon the representations and warranties of
Unity and the Company contained in the Merger Agreement, and has not
independently attempted to verify such information. McDonald & Company has also
assumed that all of the conditions to the Merger as set forth in the Merger
Agreement, including the tax-free treatment of the Merger to the holders of
Unity Common Shares, would be satisfied and that the Merger would be consummated
on a timely basis in the manner contemplated by the Merger Agreement. No
limitations were imposed by Unity upon McDonald & Company with respect to the
scope of McDonald & Company's investigation, nor were any specific instructions
given to McDonald & Company in connection with its fairness opinion.

         In connection with rendering its opinion, McDonald & Company considered
a variety of financial analyses, which are summarized below. McDonald & Company
believes that its analyses must be considered as a whole and that selecting
portions of such analyses and of the factors considered by McDonald & Company
without considering all such analyses and factors may create an incomplete view
of the analytical process underlying McDonald & Company's opinion. In its
analyses, McDonald & Company made numerous assumptions with respect to industry
performance, business and economic conditions, and other matters. Any estimates
contained in McDonald & Company's analyses are not necessarily indicative of
future results or values, which may be significantly more or less favorable than
such estimates.

        The following is a summary of selected analyses considered by McDonald &
Company and discussed with the Unity Board of Directors, in connection with
McDonald & Company's opinion dated April 28, 1997:

        COMPARISON WITH SELECTED COMPANIES. McDonald & Company compared the
financial performance and stock market valuation of the Company with
corresponding data for the following selected financial service companies: ANB
Corporation, Belmont Bancorp., Bryn Mawr Bank Corporation, Cass Commercial
Corporation, Capitol Bancorp, Ltd., Comm Bancorp Inc., Commercial BancShares
Inc., Century Financial Corporation, NSD Bancorp, Inc., Peoples Bank Corporation
of Indianapolis, Southside Bancshares Corp., S.Y. Bancorp, Inc., and United
Bancorp, Inc. In addition, McDonald & Company compared the same data of Unity
with corresponding data for the following selected companies: East Side
Financial, Inc., GF Bancorp, Inc., HFB Financial Corporation, Illinois Community
Bancorp, Inc., Mid-Central Financial Corp., NorthWest Indiana Bancorp, Peoples
Savings Bank of Troy, Pioneer Financial Corporation, TSB Financial Incorporated,
West Town Bancorp, Inc., as well as Community Investors Bancorp, Classic
Bancshares, Inc., Enterprise Federal Bancorp, FFW Corp., Wood Bancorp, Inc.,
Laurel Capital Group, Inc., MFB Corp., OHSL Financial Corp., Pittsburgh Home
Financial Corp, and Three Rivers Financial Corp. At the time, none of the
companies listed above had announced a merger transaction or disclosed an
interest in pursuing a possible merger transaction which would have
significantly affected its stock market valuation.

        CONTRIBUTION ANALYSIS. McDonald & Company analyzed the contribution of
each of Unity and the Company to, among other things, the shareholders' equity
and after-tax income of the pro forma combined company. This analysis showed
that, among other factors, Unity would have contributed 24.1% of the stated
shareholders' equity of the pro forma combined company as of March 31, 1997 and
18.7% of the pro forma net income for the combined company for the 12 months
ended March 31, 1997, compared to a proposed ownership of 21.1% of the combined
company to be held by holders of Unity Common Shares.

        PRO FORMA MERGER ANALYSIS. McDonald & Company analyzed certain pro forma
effects resulting from the Merger on the pro forma combined company over a
five-year period from 1997 through 2001. This analysis, based upon the financial
forecasts of management of Unity and the Company and including estimates of cost
savings provided by the management of Unity and the Company, showed
approximately 3.1% dilution for the Company in pro forma earnings per share in
1997 and approximately 0.6% dilution in pro forma earnings per share in 1998.
McDonald & Company also analyzed the changes in the per share amount of
earnings, book value and indicated dividend represented by one Unity Common
Share after the Merger. The analysis was performed on the basis of financial
information for both companies as of and for the 12-month periods ended December
31, 1994, 1995 and 1996 and the 12 -month period ended March 31, 1997. The
analysis indicated that, among other things, exchanging one Unity Common Share
at the Exchange Ratio for shares of Oak Hill Common Stock on a pro forma basis
would have resulted in a 48.7% increase in earnings per share for each Unity
Common Share for the 12 months ended March 31, 1997, a 10.1% decrease in fully
diluted book value per share for each Unity Common Shares as of March 31, 1997
and a dividend increase of 2.0% per share of Unity Common Shares based on the
Company's indicated annual dividend rate as of the date of the opinion.

        ANALYSIS OF SELECTED MERGER TRANSITIONS. McDonald & Company reviewed
five groups of selected pending thrift acquisition transactions involving (i)
selling thrifts, headquartered in the Midwest region of Iowa, Illinois, Indiana,
Kansas, Kentucky, Michigan, Minnesota, Missouri, North Dakota, Nebraska, Ohio,
Pennsylvania, South Dakota, West Virginia and Wisconsin, (ii) selling thrifts
with total assets less than $250 million, (iii) selling thrifts with an equity
to assets ratio of between 9.00% and 15.00%, (iv) selling thrifts with a return
on average assets ratio of between 0.50% and 1.00%, and (v) selling thrifts with
a ratio of non-performing assets to total assets of less than 1.00%. McDonald &
Company reviewed the ratios of the offer value to stated book value and tangible
book value, the multiple of the last 12 months earnings of the acquired company
(adjusted for the SAIF charge), and the ratio of offer value to assets in each
such transaction, and computed the mean and median ratios and multiples for each
group. The calculations yielded ranges of median ratios of price to stated book
value and tangible book value of 119% to 152% and 119% to 156%, respectively.
Median multiples of earnings among the five groups ranged from 20.3x to 25.5x;
and median ratios of offer value to assets ranged from 17.0% to 19.5%. This
analysis showed an imputed reference range of $126.00 to $154.00 per Unity
Common Share.

        NO COMPANY OR TRANSACTION USED IN THE ABOVE ANALYSES AS A COMPARISON IS
IDENTICAL TO UNITY, THE COMPANY OR THE MERGER. ACCORDINGLY, AN ANALYSIS OF THE
RESULTS OF THE FOREGOING NECESSARILY INVOLVES COMPLEX CONSIDERATIONS AND
JUDGMENTS CONCERNING THE DIFFERENCES IN FINANCIAL AND OPERATING CHARACTERISTICS
OF THE COMPANIES TO WHICH THEY ARE BEING COMPARED. MATHEMATICAL ANALYSIS (SUCH
AS DETERMINING THE MEAN OR MEDIAN) IS NOT, IN ITSELF, A MEANINGFUL METHOD OF
USING COMPARABLE COMPANY OR COMPARABLE TRANSACTION DATA.

        DISCOUNTED CASH FLOW ANALYSIS. Using discounted cash flow analysis,
McDonald & Company estimated the present value of the future streams of
after-tax cash flows that Unity could produce over a five-year period from 1997
through 2001, under various assumptions, based upon Unity's management
forecasts. McDonald & Company then estimated the terminal value of Unity after
the five year period by applying an estimated perpetual growth rate to the sixth
year's projected after-tax cash flow and then applied to this value multiples
ranging from 8.1X to 10.1X. The five year cash flow streams and terminal values
were then discounted to present values using different discount rates chosen to
reflect different assumptions regarding the estimated required rates of return
of prospective buyers of Unity. On the basis of such varying assumptions, this
discounted cash flow analysis indicated a reference range of $98.32 to $122.46
per Unity Common Share. This analysis was based upon management forecasts
including variations and assumptions made by McDonald & Company which included
adjustments to reflect the anticipated effects of potential merger related cost
savings estimated by Unity and the Company. Management's forecasts are based
upon many factors and assumptions, many of which are beyond the control of Unity
or the Company.

        In addition to performing the analyses summarized above, McDonald &
Company also considered its analyses of the general market for bank and thrift 
mergers, Unity's relative share of the deposit market that it serves and the 
general economic conditions and prospects of the markets.

        In performing its analyses, McDonald & Company made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters. The analyses performed by McDonald & Company are not
necessarily indicative of actual values, which may be significantly more or less
favorable than the values suggested by such analyses. Such analyses were
prepared solely as part of McDonald & Company's opinion.

        The term "fair from a financial point of view" is a standard phrase
contained in investment banking fairness opinions and refers to the fact that
McDonald & Company's opinion as to the fairness of the Exchange Ratio is
addressed solely to the financial attributes of the Exchange Ratio. The analyses
do not purport to be appraisals or to reflect the prices at which a company
might actually be sold. In addition, as described above, McDonald & Company's
opinion and related presentation to the Unity Board of Directors were one of
many factors taken into consideration by the Unity Board in making its
determination to approve the Merger Agreement. Consequently, the McDonald &
Company analyses described above should not be viewed as determinative of the
Unity Board's conclusions with respect to the value of Unity or of the decision
of the Unity Board to agree to the Exchange Ratio.

        McDonald & Company's opinion is based on economic and market conditions
and other circumstances existing on, and information made available as of, the
date of the opinion. In addition, the opinion does not address the underlying
business decision to effect the Merger or any other terms of the Merger.
McDonald & Company's opinion does not represent its opinion as to what the value
of Unity Common Shares or Oak Hill Common Stock may be at the Effective Time.

        In connection with its opinion dated as of the date of this
Prospectus/Proxy Statement, McDonald & Company performed procedures to update
certain of its analyses and reviewed the assumptions on which such analyses were
based and the factors considered herewith.

        McDonald & Company, as part of its investment banking business, is
customarily engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. McDonald & Company has
extensive experience with the valuation of financial institutions. Unity's Board
of Directors selected McDonald & Company as its financial advisor because of
McDonald & Company's industry expertise with respect to financial institutions
and because of its substantial experience in transactions similar to the Merger.
McDonald & Company is not affiliated with either Unity or the Company.

        In the ordinary course of business, McDonald & Company makes a market in
Oak Hill Common Stock and may actively trade securities of the Company or Unity
for its own account and for the accounts of its customers. At any time and from
time to time, McDonald & Company may hold a short or long position in such
securities. In addition, 


                                      -17-

McDonald & Company has provided investment banking services to the Company in
the past, serving as managing underwriter for an initial public offering of Oak
Hill's Common Stock, McDonald & Company received customary fees from the
Company for these services. McDonald & Company may provide other investment
banking services to the Company in the future.

        For its services as financial advisor, Unity has paid McDonald & Company
a fee of $40,000 upon rendering of the oral opinion. Assuming the consummation
of the Merger and based upon the value of the Merger assuming a per share merger
price of [price of Oak Hill Common Stock just before printing proxy], additional
fees equal to approximately $160,000 would be payable to McDonald & Company upon
consummation of the Merger. Unity has also agreed to reimburse McDonald &
Company for its reasonable out-of-pocket expenses and to indemnify McDonald &
Company against certain liabilities, including certain liabilities under federal
securities laws.

REQUIRED VOTE

        Under the OGCL and Unity's Amended and Restated Articles of
Incorporation ("Unity Articles"), adoption of the Merger Agreement requires the
affirmative vote of the holders of two-thirds of the outstanding Unity Common
Shares. As of the Unity Record Date the directors and executive officers of
Unity and their affiliates beneficially owned 63,525.8 Unity Common Shares,
which represent 68.1% of the total issued and outstanding shares.

        The affirmative vote of the holders of a majority of the shares of Oak
Hill Common Stock voting on the Merger Agreement is necessary to adopt the
Merger Agreement. As of the Oak Hill Record Date, the directors and executive
officers of the Company and their affiliates beneficially owned 1,816,623 shares

represent 63.2% of the total issued and outstanding shares of such stock
entitled to vote at the Oak Hill Special Meeting.

THE MERGER AGREEMENT

        The following is a brief summary of certain provisions of the Merger
Agreement, a copy of which is attached as Appendix A to this Prospectus/Proxy
Statement and is incorporated herein by reference. Such summary is qualified in
its entirety by reference to the Merger Agreement. Shareholders are urged to
read the Merger Agreement carefully.

        The Merger Agreement provides that, following the approval of the
issuance of the Merger Consideration by the shareholders of the Oak Hill Common
Stock and adoption of the Merger Agreement by the shareholders of Unity, and the
satisfaction or waiver of the other conditions to the Merger, Unity will be
merged with and into the Bank, with the Bank continuing as the surviving
corporation of the Merger and continuing as a wholly-owned subsidiary of the
Company.

        Upon the satisfaction or waiver of all conditions to the Merger, the
Merger will become effective upon the filing of a certificate of merger by the
Bank and Unity with the Secretary of State of the State of Ohio in accordance
with the OGCL. The Effective Time of the Merger is expected to occur on or about
__________ __, 1997.

        MERGER CONSIDERATION GENERALLY. Each outstanding Unity Common Share
shall be converted into the right to receive 8.5 shares of Oak Hill Common Stock
(the "Exchange Ratio"), with the 8.5 shares subject to adjustment downward if
the average of the daily average of the closing bid and asked prices of the Oak
Hill Common Stock, as reported on The Nasdaq National Market, for the 20 most
recent full trading days in which such shares are traded on The Nasdaq National
Market, ending on the date three days prior to Closing of the Merger (the
"Average Closing Price") is greater than $16.01. In that event, each outstanding
share of Unity Common Shares shall be converted into the right to receive such
number of shares as is equal to the product of multiplying 8.5 shares by a
fraction, the numerator of which is $16.01 and the denominator of which is the
Average Closing Price. The Exchange Ratio shall be further adjusted to reflect
any non-cash distribution, stock splits or stock dividends on the Oak Hill
Common Stock occurring or having a record date after the date hereof and prior
to the Effective Time.

        FRACTIONAL SHARES. No fractional shares of Oak Hill Common Stock shall
be issued. Each holder of Unity Common Shares who would otherwise be entitled to
receive a fractional part of a share of Oak Hill Common Stock shall instead be
entitled to receive cash in an amount equal to the product resulting from
multiplying such fraction by the Average Closing Price per share of Oak Hill
Common Stock. No interest shall be payable with respect to such cash payment.

        COMMON STOCK OF THE BANK. At the Effective Time, each share of common
stock, $1,000 par value, of the Bank that is issued and outstanding immediately
prior to the Effective Time will, by virtue of the Merger, continue to be the
issued and outstanding shares of the Bank without change.

        CONDITIONS TO CONSUMMATION OF THE MERGER. The respective obligations of
the Company, the Bank and Unity to consummate the Merger are subject to the
fulfillment or waiver by the parties of certain mutual conditions, including:

        TERMINATION. The Merger Agreement shall terminate on December 31, 1997,
unless a later date is agreed upon in writing by the parties, and may be

Time as follows:

                  (a) by the mutual consent, evidenced in writing, of the Boards
of Directors of the Company, the Bank, and Unity;

                  (b) by the Board of Directors of the Company, by giving
written notice thereof to Unity, which notice shall specify in reasonable detail
the grounds therefor: (i) if any condition precedent to performance by the
Company and the Bank has not been satisfied or waived; (ii) if Unity has not
fully performed its obligations and agreements under the Merger Agreement; or
(iii) if any of the representations of Unity set forth in the Merger Agreement
are untrue or incorrect in any material respect; or

                  (c) by the Board of Directors of Unity, by giving written
notice thereof to the Company, which notice shall specify in reasonable detail
the grounds therefor: (i) if any condition precedent to performance by Unity has
not been satisfied or waived; (ii) if the Company and the Bank have not fully
performed their obligations and agreements under the Merger Agreement; or (iii)
if any of the representations of the Company set forth in the Merger Agreement
are untrue or incorrect in any material respect.

DISSENTERS' RIGHTS

        THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW
PERTAINING TO DISSENTING SHAREHOLDER RIGHTS UNDER THE OGCL AND IS QUALIFIED IN
ITS ENTIRETY BY THE FULL TEXT OF SECTION 1701.85 WHICH IS REPRINTED IN ITS
ENTIRETY AS APPENDIX D TO THIS PROSPECTUS.

        Shareholders of Unity who (i) are shareholders of record on the Unity
Record Date, (ii) do not vote in favor of adoption of the Merger Agreement, and
(iii) who, within 10 days after the date of the vote on the Merger Agreement is
taken, deliver written demand in compliance with the provisions of Section
1701.85(A)(2) of the OGCL, shall be entitled to receive the fair cash value of
the shares that were not voted in favor of the Merger. The written demand must
set forth the shareholder's address, the number and class of stocks as to which
the shareholder seeks relief (the "Dissenting Shares") and the amount the
shareholder claims as the fair cash value of the Dissenting Shares.

        If Unity receives a written demand from a shareholder seeking the fair
cash value of Dissenting Shares, it may request the surrender of the certificate
or certificates that represent the Dissenting Shares. The dissenting shareholder
must deliver the certificate or certificates representing the Dissenting Shares
to Unity within 15 days of the date of its request therefor or the shareholder's
rights with respect to the Dissenting Shares will terminate. If the certificate
or certificates representing the Dissenting Shares are delivered to Unity, it
must promptly endorse the certificates with a legend to the effect that a demand
for the fair cash value for the Dissenting Shares has been made and return the
certificates to the dissenting shareholder.

        If Unity and the dissenting shareholder cannot agree on the fair cash
value of the Dissenting Shares, then either may, within three months after the
date of the service of the demand for fair cash value was made by the dissenting
shareholder, file a complaint in the court of common pleas of Vinton County,
Ohio. The court will first make a determination if the dissenting shareholder is
entitled to receive the fair cash value for the Dissenting Shares. If the court
determines that the dissenting shareholder is entitled to fair cash value for
the Dissenting Shares, the court will appoint an appraiser or appraisers to make
a finding as to the fair cash value of the Dissenting Shares.

        The fair cash value will be determined based on what a willing seller
who is under no compulsion to sell would be willing to accept and what a willing
buyer who is under no compulsion to purchase would be willing to pay for the
Dissenting Shares. In no event will the fair cash value exceed the amount stated
in the written demand by the dissenting shareholder. In computing the fair cash
value, any appreciation or depreciation in the market value resulting from the
Merger shall be excluded.

        The fair cash value that is agreed upon between the parties or that is
determined by the court shall be paid within 30 days after the date of the final
determination of such value or the consummation of the Merger, whichever occurs
last. Payment shall be made only upon and simultaneously with the surrender to
Unity of the certificate or certificates representing the Dissenting Shares.

        The costs of the action, including reasonable compensation to the
appraisers, will be fixed by the court and will be assessed or apportioned as
the court considers equitable.

        A shareholder's right to receive the fair cash value for the Dissenting
Shares terminates if (i) the dissenting shareholder does not strictly comply
with the requirements of Section 1701.85, (ii) the Merger is abandoned, (iii)
the dissenting shareholder withdraws the demand for fair cash value, or (iv)
Unity and the dissenting shareholder have not come to an agreement regarding the
fair cash value of the Dissenting Shares and neither has filed a complaint with
the Vinton County Court of Common Pleas within the time period described in
Section 1701.85(B).

        FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 1701.85 OF THE OGCL FOR
PERFECTING DISSENTING SHAREHOLDER RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS
(IN WHICH EVENT THE DISSENTING SHAREHOLDER WILL BE ENTITLED TO RECEIVE THE
MERGER CONSIDERATION IN ACCORDANCE WITH THE MERGER AGREEMENT).

EXCHANGE OF CERTIFICATES

        The Fifth Third Bank (the "Exchange Agent") will deliver to the
shareholders of Unity, a letter of transmittal ("Letter of Transmittal") and
instructions in effecting the surrender of certificates representing Unity
Common Shares in exchange for certificates representing shares of Oak Hill
Common Stock and cash in lieu of fractional shares thereof.

        Upon surrender of a certificate to the Exchange Agent, together with a
duly executed Letter of Transmittal and any other required documents, the
shareholders of Unity will be entitled to receive, in exchange therefor, a
certificate representing their proportion of shares of Oak Hill Common Stock and
a check representing cash in lieu of any fractional shares of Oak Hill Common
Stock. No interest will be paid or will accrue on any amount payable upon
surrender of the certificates previously representing Unity Common Shares.

        After the Effective Time, each certificate evidencing Unity Common
Shares, until so surrendered and exchanged, will be deemed, for all purposes, to
evidence only the right to receive the consideration into which such shares have
been converted in the Merger.

        UNITY SHAREHOLDERS SHOULD NOT SUBMIT ANY STOCK CERTIFICATES NOW BUT
RATHER SHOULD ONLY SUBMIT STOCK CERTIFICATES ONLY UPON RECEIPT OF, AND TOGETHER
WITH, THE LETTER OF TRANSMITTAL AND INSTRUCTIONS ENCLOSED THEREWITH.

STOCK EXCHANGE LISTING

        A notification has been filed to list on The Nasdaq National Market the
Oak Hill Common Stock issuable in connection with the Merger. Listing of such
shares of Oak Hill Common Stock to be issued in the Merger, subject to official
notice of issuance, is a condition precedent to consummation of the Merger.

REGULATORY APPROVALS

        It is anticipated that the Merger will qualify for an exemption from the
Federal Reserve Board's general requirement of an application for bank holding
company mergers. Such exemptions apply to certain acquisitions that are subject
to the Bank Merger Act, and require, for qualifying transactions, only a 30-day
prior notice to the relevant Federal Reserve Bank, which in this case is the
Federal Reserve Bank of Cleveland. The Merger is subject to the Bank Merger Act
and must be approved by the FDIC and the Ohio Superintendent of Financial
Institutions. An application to the FDIC and the Ohio Superintendent of
Financial Institutions was filed, and a notice to the Federal Reserve Bank of
Cleveland was submitted, on June 30, 1997.

        Approval by the FDIC requires that the criteria of the Bank Merger Act
be met. In conducting its review of any application under the Bank Merger Act,
the FDIC is required to take into consideration the financial and managerial
resources and (including the competence, experience, and integrity of the
officers, directors, and principal shareholders), the future prospects of the
existing and proposed institutions, and the convenience and needs of the
communities to be served. In considering financial resources and future
prospects, the FDIC will, among other things, evaluate the adequacy of the
capital levels of the parties to a proposed transaction.

        Ohio law and the Bank Merger Act also prohibit the Superintendent of
Financial Institutions and the FDIC from approving a merger if it would result
in a monopoly or be in furtherance of any combination or conspiracy to
monopolize or to attempt to monopolize the business of banking in any part of
the Untied States, or if its effect in any section of the country would be
substantially to lessen competition or tend to create a monopoly, or if it would
in any other manner result in a restraint of trade, unless it is determined that
the anti-competitive effects of a merger are clearly outweighed in the public
interest by the probable effect of the transaction in meeting the convenience
and needs of the communities to be served. In addition, under the Community
Reinvestment Act of 1977, as amended, the FDIC must take into account the record
of performance of the existing institutions in meeting the credit needs of the
entire community, including low- and moderate-income neighborhoods, served by
such institutions.

        Ohio law and the Bank Merger Act provide for the publication of notice
of, and the opportunity for administrative hearings relating to, the application
for approval noted and described above. Interested parties may intervene in the
approval proceedings. If an interested party intervenes, such intervention could
substantially delay the regulatory approvals required for consummation of the
Merger. Any merger approved by the FDIC is subject to a statutory waiting period
of 15 to 30 days, during which time the United States Department of Justice may
challenge a merger on antitrust grounds. The commencement of an antitrust action
would stay the effectiveness of the regulatory agency's approval unless a court
specifically ordered otherwise.

        The managements of the Company and Unity believe that the FDIC and the
Ohio Superintendent of Financial Institutions will approve the applications
filed with them, that the Federal Reserve Board will waive any application that
would otherwise be required under the Bank Holding Company Act, and that the
Merger will not be subject to challenge by the Department of Justice under the
antitrust laws. However, no assurance can be provided that such approval will be
obtained, that such waiver will be granted, that the Department of Justice will
not challenge the Merger under the antitrust laws, or that the approval by the
FDIC and the Ohio Superintendent of Financial Institutions will not contain
conditions unacceptable to either the Company or Unity. See "THE MERGER -
Conditions to Consummation of the Merger."

ANTICIPATED ACCOUNTING TREATMENT

        The Company intends to account for the Merger using the pooling of
interests method of accounting under generally accepted accounting principles
and the rules and regulations of the Commission.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

        The following is a summary of certain material United States federal
income tax consequences of the Merger. This summary is based on the Internal
Revenue Code of 1986, as amended (the "Code"), and is for general information
only. This summary is not a complete description of all the possible tax
consequences of the Merger and the tax treatment of a particular shareholder
will depend upon such shareholder's particular situation. Special tax
considerations not discussed herein may be applicable to particular classes of
taxpayers, such as foreign shareholders, broker-dealers, certain retirement
plans, financial institutions, or insurance companies, or to any shareholder who
does not hold Unity Common Shares as a capital asset or who acquired Unity
Common Shares through the exercise of an employee stock option or otherwise as
compensation. All shareholders should consult with their own tax advisors as to
particular tax consequences of the Merger to them, including the applicability
and effect of state, local and foreign tax laws and possible changes in the tax
law.

        Consummation of the Merger is dependent upon receipt by the Company and
Unity of an opinion of Porter, Wright, Morris & Arthur, counsel to the Company,
substantially to the effect that, for federal income tax purposes, the Merger
will constitute a reorganization within the meaning of Section 368(a) of the
Code and will result in the tax consequences described below. In rendering such
opinion, Porter, Wright, Morris & Arthur is entitled to rely upon certain
assumptions and representations of the parties and their respective officers,
directors, and shareholders, which representations will not be independently
investigated or verified by Porter, Wright, Morris & Arthur and will be assumed
to be true as of the Effective Time.

        Assuming that the Merger constitutes a reorganization within the meaning
of Section 368(a) and that the Company, the Bank and Unity will each be a party
to the reorganization within the meaning of Section 368(b) of the Code, the
following is a summary of the tax consequences which will result:

        RECEIPT OF OAK HILL COMMON STOCK. The shareholders of Unity will not
recognize gain or loss upon receipt of Oak Hill Common Stock in the Merger
(except for cash received in lieu of fractional shares as described below) in
exchange for all shares of Unity Common Shares owned by them for federal income
tax purposes. The tax basis of the Oak Hill Common Stock received in such an
exchange will be equal to the basis of the Unity Common Shares exchanged
therefor (except for the basis attributable to any fractional shares of Oak Hill
Common Stock for which cash is paid, as discussed below). The holding period for
tax purposes of the Oak Hill Common Stock to be received by Unity shareholders
will include the holding period of the shares of Unity Common Shares surrendered
in exchange therefor, provided that Unity Common Shares were held as a capital
asset in the hands of the Unity shareholder at the Effective Time.

        CASH RECEIVED IN LIEU OF FRACTIONAL SHARES. The shareholders of Unity,
upon receipt of cash in the Merger in lieu of a fractional share interest in Oak
Hill Common Stock, will be treated for federal income tax purposes as having
received such fractional share interest and sold it for the cash received.
Shareholders will recognize gain or loss as of the Effective Time equal to the
difference between the amount of cash received and the portion of the
shareholder's adjusted tax basis in the Unity Common Shares exchanged for the
fractional share interest that is deemed sold. Such gain or loss will be capital
gain or loss if the stockholder holds the Unity Common Shares exchanged for the
fractional share as a capital asset and will be long-term capital gain or loss
if such Unity Common Shares is considered to have been held for more than one
year at the Effective Time.

        TAX CONSEQUENCES TO THE COMPANY, THE BANK, AND UNITY. No gain or loss
will be recognized by the Company, the Bank, or Unity (except for the inclusion
in income of amounts resulting from any required changes in accounting methods
or similar items) as a result of the consummation of the Merger.

        DISSENTERS' RIGHTS. If a shareholder of Unity dissents to the
transaction and receives solely cash in exchange for the shareholder's Unity
Common Shares, such cash will be treated as having been received as a
distribution in redemption of such shareholders Unity Common Shares, subject to
the provisions and limitations of Section 302 of the Code. Where, as a result of
such distribution, the shareholder owns no Oak Hill Common Stock, either
directly or by reason of the application of Section 318 of the Code, the
redemption will be a complete termination of interest within the meaning of
section 302(b)(3), and such cash will be treated as a distribution in full
payment in exchange for his or her Unity Common Shares as provided in section
302(a) of the Code. Such shareholder will recognize gain or loss (subject to
Section 267 of the Code) under section 1001 of the Code measured by the
difference between the amount of cash received and the adjusted basis of the
Unity Common Shares surrendered.

        BACKUP WITHHOLDING. Under federal income tax law concerning "backup
withholding," the Company will be required to withhold, and will withhold, 31%
of any cash payments to which a shareholder of Unity is entitled pursuant to the
Merger unless the holder provides its taxpayer identification number and
certifies that such number is correct or otherwise establishes that the holder
is an exempt holder (such as a corporation or certain foreign individuals,


                                      -22-
<PAGE>   32
partnerships or trusts). Each holder should sign the Substitute Form W-9
included as part of the Transmittal Letter (or in the case of a nonresident
alien or foreign entity, a Form W-8) to prevent backup withholding.

        The foregoing discussion is based on currently existing provisions of
the Code, existing and proposed treasury regulations thereunder, and current
administrative rulings and court decisions. The opinion of counsel described
above is not binding on the Internal Revenue Service and no rulings of the
Internal Revenue Service will be sought or obtained in relation to the Merger.
There can be no assurance that the Internal Revenue Service will agree with the
tax consequences of the Merger described above. All of the foregoing discussion
is subject to change and any such change could affect the continuing validity of
such discussion.

        SHAREHOLDERS OF UNITY ARE ADVISED TO CONSULT WITH THEIR OWN TAX ADVISERS
CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER, AS WELL AS THE
APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON ITS
PARTICULAR FACTS AND CIRCUMSTANCES.

RESALES BY AFFILIATES

        Certain shareholders of Unity that are deemed "affiliates" of Unity for
purposes of Rule 145 under the Securities Act ("Rule 145") will not be permitted
to transfer their shares of Oak Hill Common Stock issued in the Merger except
(i) pursuant to an effective registration statement under the Securities Act;
(ii) in compliance with Rule 145; or (iii) pursuant to an exemption from the
registration requirements of the Securities Act. The Company shall be entitled
to place appropriate legends on the certificates evidencing the Oak Hill Common
Stock to be received by Unity's shareholders deemed to be affiliates, and to
issue appropriate stock transfer instructions to the transfer agent for Oak Hill
Common Stock, to the effect that the shares received or to be received by such
Unity shareholders pursuant to the Merger may only be sold, transferred or
otherwise conveyed pursuant to an effective registration statement under the
Securities Act, in accordance with the provisions of paragraph (d) of Rule 145
or pursuant to an exemption from registration provided under the Securities Act.
Pursuant to the terms of the Merger Agreement, it is a condition to consummation
of the Merger that those individuals deemed to be affiliates of Unity deliver a
written agreement to the Company stating that they will not sell, transfer, or
dispose of their shares of Oak Hill Common Stock received in the Merger except
in accordance with the provisions of paragraph (d) of Rule 145 or pursuant to an
exemption from registration provided under the Securities Act. This
Prospectus/Proxy Statement does not cover any resales of Oak Hill Common Stock
received by Unity's shareholders.


                          CERTAIN RELATED TRANSACTIONS

        In considering the recommendation of Unity's and the Company's Boards of
Directors with respect to the Merger, Unity's and the Company's stockholders
should be aware that certain members of Unity management at the time of the
approval of the Merger Agreement and the Merger had, and currently have, certain
interests in related transactions to the Merger.

EMPLOYMENT OF D. BRUCE KNOX

        D. Bruce Knox, the President of Unity, has entered into a an employment
agreement with the Bank to serve as its Senior Vice President for a period of
three years (the "initial period") commencing on the effective date of the
Merger and the employment agreement provides that Mr. Knox shall be appointed to
the boards of directors of the Company and the Bank. The employment agreement
may be extended by the mutual agreement of Mr. Knox and the Company. Mr. Knox's
employment may also become an employment "at will" if the agreement is not
extended and he continues in the employment of the Company after the initial
term of the agreement. The agreement provides that he shall have the duties and
responsibilities normally associated with his position and that he shall devote
his full business time and effort to the performance of his duties under the
agreement.

        The agreement provides that the Company shall pay Mr. Knox a base salary
of $100,000; that he shall receive directors' fees in addition to other
compensation; that he shall be eligible to participate in the Company's 1997
bonus compensation program; and that he shall receive options to purchase the
Company's common stock at the then-prevailing market prices under the Company's
1995 Stock Option Plan as specified in the agreement. The agreement also
provides that he shall receive reimbursement of business expenses in accordance
with the Company's standard practices, and that he shall be eligible to
participate in all group insurance and other benefit plans and programs made
available by the Company to its employees generally.

        The agreement also provides that if he is terminated without cause
during the initial period, the Company will pay to him a sum equal to the
remaining unpaid salary for the initial period, in equal monthly installments
which commence on the date of his termination and continue until the termination
of the initial period. In such event, the Company must also provide health,
life, disability and other benefits to Mr. Knox until the end of the initial
period. Mr. Knox is not required to mitigate the amounts of these payments by
seeking other employment.

MODIFICATION OF EXECUTIVE SALARY CONTINUATION AGREEMENTS

        On December 5, 1994, Unity entered into certain executive salary
continuation agreements with D. Bruce Knox and George Knox. The agreements
provided for annual retirement benefits of $67,473 and $36,000, respectively.
The benefits would begin at retirement (age 65 for D. Bruce Knox and age 70 for
George Knox) and would be payable monthly for 15 years. On September 19, 1995,
the agreements were modified to provided that the benefits did not vest in full
until the stated retirement dates.

        The agreements provide that the benefits vest upon a change in control
of Unity which is defined in the agreement to be a cumulative transfer, from the
date of the agreements, to any party other than current shareholders of more
than fifty percent of the common stock of Unity, disregarding transactions
between family members.

        In connection with the agreements, in May 1994, Unity purchased single
premium insurance contracts to finance the benefits payable under the
agreements. As of December 31, 1996, the policy related to the agreement with D.
Bruce Knox had a cash surrender value of $138,706, and the policy related to the
agreement with George Knox had a cash surrender value of $437,452. Unity has
established a liability reserve account in connection with the salary
continuation agreements which on March 31, 1997, had a value of approximately
$129,000.

        In connection with the execution of the Merger Agreement on April 28,
1997, the salary continuation agreement with George Knox was amended, effective
that date, to provide for his retirement on May 31, 1997 (subsequently amended
to June 30, 1997). The agreement with George Knox, as amended, provides that
monthly benefits shall be payable for 211 months.

        The Merger constitutes a change of control for purposes of the salary
continuation agreements. As a result, the Merger Agreement provides, as a
condition to the obligation of the Company to consummate the Merger, that the
salary continuation agreement with D. Bruce Knox is to be terminated and all
claims thereunder released in return for a payment of $206,000.

(1)      The Pro Forma Unaudited Condensed Combined Consolidated Statements of
         Financial Condition assume that the Merger is accounted for as a
         pooling of interests. Accordingly, the Company and Unity's assets,
         liabilities and stockholders' equity are added together at the
         historical carrying values. Both of the companies utilize the same
         accounting methods and there were no intercompany transactions affected

GENERAL

         The Company is a bank holding company that engages indirectly in the
business of commercial banking, and other permissible activities closely related
to banking, through a wholly owned subsidiary, the Bank. The Company provides
management and similar services for the Bank. Since it does not itself conduct
any operating businesses, the Company must depend largely upon the Bank for
funds with which to pay the expenses of its operation and, to the extent
applicable, any dividends on its outstanding shares of stock.

         The Company was formed in 1981 for the purpose of becoming the parent
holding company of the Bank. The Company is registered as a bank holding company
under the Bank Holding Company Act of 1956, as amended. As such, the Company is
subject to strict regulation regarding the acquisition of additional financial
institutions and the conduct through subsidiaries of non-banking activities. See
"Regulation," below.

         The Company faces strong competition from both banking and non-banking
institutions. Its banking competitors include local and regional banks and bank
holding companies, as well as some of the largest banking organizations in the
United States. In addition, other types of financial institutions, such as
savings and loan associations and credit unions, also offer a wide range of loan
and deposit services that are directly competitive with those offered by the
Bank. The consumer is also served by brokerage firms and mutual funds that
provide checking services, credit cards, and other services similar to those
offered by the Bank. Major stores compete for loans by offering credit cards and
retail installment contracts. It is anticipated that competition from non-bank
and non-savings and loan organizations will continue to grow.

         The range of banking services provided by the Bank to its customers
includes commercial lending, real estate lending, consumer credit, credit card,
and other personal loan financing. The Bank operates under the direction of its
own board of directors and officers.

LENDING ACTIVITIES

         GENERAL. The Company generally makes loans in the four counties in
which its branches are located. The Company's principal lending activities are
the origination of (i) conventional one- to four-family residential loans, and
(ii) commercial loans, most of which are secured by real estate located in the
Company's primary market area. These loan categories accounted for approximately
83% of the Company's loan portfolio at March 31, 1997. The Company also makes
consumer loans, including installment loans and second mortgages, and offers
credit cards.

         LOAN PORTFOLIO COMPOSITION AND ACTIVITY. The following table sets forth
the composition of the Company's loan portfolio, including loans held for sale,
in dollar amounts and in percentages for each of the last five years, along with

         LOANS SECURED BY ONE- TO FOUR-FAMILY REAL ESTATE. A significant portion
of the Company's lending activity is the origination of permanent conventional
loans secured by one- to four-family residences located within the Company's
primary market area. The Company typically makes adjustable rate mortgage loans
and holds the loans in portfolio. More than 73% the Company's portfolio of
permanent conventional mortgage loans secured by one- to four-family residences
are adjustable rate. The Company also underwrites fixed rate, residential
mortgage loans, but then sells those loans in the secondary market to the FHLMC
or on a servicing-released basis to another financial institution.

         The Company makes fixed rate loans on one- to four-family residences up
to 95% of the value of the real estate and improvements (the "loan-to-value" or
"LTV") substantially all of which are sold in the secondary market. Residential
real estate loans are offered by the Company for terms of up to 30 years. The
Company requires private mortgage insurance for the amount of such loans in
excess of 80% of the value of the real estate securing such loans.

         The aggregate amount of the Company's one- to four-family residential
real estate loans equaled approximately $66.7 million at March 31, 1997 and
represented 33.8% of loans at such date. At such date, loans secured by
residential real estate with outstanding balances of approximately $418,000, or
 .6%, of its total one- to four-family residential real estate loan balance, were
more than 90 days delinquent or nonaccruing.

         COMMERCIAL LOANS. The Company is also active in commercial lending,
primarily to smaller businesses in the Company's primary market area. These
loans are typically secured by commercial real estate and priced in relation to
the prime rate. Such loans generally have terms of up to 15 years and
loan-to-value ratios of up to 75%. To a much lesser degree, the Company will
also make unsecured commercial loans, which are also typically priced at spreads
to prime and have maturities of up to one year.

         Loan officers review the financial statements, appraisals of the
collateral, and other related documents before recommending funding of a
commercial loan. The loan officer and the approving officer or committee then
determines that there is sufficient income to cover this and other loan
payments, that the collateral is of adequate liquidation value, that the
applicant has a good payment history and is capable of performing the
requirements of the loan. Other reviews and analysis are done as appropriate,
depending upon the complexity of the credit request.

         Although a risk of nonpayment exists with respect to all loans, certain
specific types of risks are associated with different types of loans. The
primary risks associated with commercial loans are the quality of the borrower's
management and the impact of national and regional economic factors. The Company
mitigates these risks by maintaining a close working relationship with its
borrowers, by obtaining cross-collateralization and personal guarantees of its
loans, and by diversification within its loan portfolio.

         Due to the nature of the Company's customer base, real estate is
frequently a material component of the collateral for its loans. The expected
source of repayment of these loans is generally the operations of the borrower's
business, but the real estate provides an additional measure of security.

         Risks associated with real estate loans include fluctuating land
values, changes in tax policies, and concentration of loans within the Company's
market area. The Company mitigates these risks by generally providing loans to
experienced commercial real estate owners and developers. The risk is further
mitigated by the number of commercial real estate loans made to the user of the
property.

         The aggregate amount of the Company's commercial loans without real
estate as primary or secondary collateral equaled approximately $20.3 million at
March 31, 1997, and represented 10.2% of loans at such date. At such date,
commercial loans that were more than 90 days delinquent or nonaccruing totaled
approximately $206,000, or .21% of its commercial loan portfolio. The aggregate
amount of the Company's commercial loans with real estate as primary or
secondary collateral was approximately $76.7 million at March 31, 1997, and at
such date, approximately $15,000 in outstanding balances, or .02% of such loans
were delinquent or nonaccruing.

         CONSUMER LOANS. The Company offers several consumer loan products:
installment loans, home equity loans and credit cards.


                                      -33-
<PAGE>   43
         The Company has a good relationship with several car dealerships in its
market area, and as a result is able to do some financing of new and used cars
through these relationships. The Company only finances cars up to six years old
and requires a down payment of 10.0%. These loans generally have fixed rates and
maturities of three to four years.

         To a lesser degree, the Company makes small unsecured loans to
creditworthy individuals. These loans are typically between $2,000 and $5,000 at
fixed rates with maturities of less than five years. The Company also offers a
home equity loan product and, as a result of consumer demand, a credit card
product to its customers. Both products are underwritten to the same standards
as any of the Company's other consumer loan products.

         Loan officers underwrite installment loan and other consumer loan
requests in such a manner to assure compliance with the various regulations and
the Company's underwriting standards. Payment history on applicants is very
important on these smaller loans, and is checked through in-house records as
well as credit bureaus. Normally collateral, such as an automobile, is taken as
security and the value is checked through the N.A.D.A. book or another valuation
service. Income must be adequate to cover all monthly payments including the
proposed loan.

         At March 31, 1997, the Company had approximately $36.1 million in its
consumer loan portfolio, which was 18.4% of the Company's total loans.
Approximately $213,000 of consumer loans were over 90 days delinquent or
nonaccruing on that date, which represented .06% of the consumer loan portfolio.

         LOAN SOLICITATION AND PROCESSING. Loan originations are developed from
a number of sources, including continuing business with depositors, other
borrowers and real estate developers, solicitations by the Company's lending
staff and walk-in customers.

         Underwriting guidelines for all branches and loan types are set by
senior management at the home office. Loan processing and underwriting, however,
are decentralized. Loan applications are generally processed and underwritten at
the branch level. Loan officers and branch managers review the applications, as
well as credit bureau reports, appraisals, financial information, verifications
of income, and other documentation concerning the credit-worthiness of the
borrower, as applicable to each loan type.

         Commercial loans are underwritten at the branch level with oversight by
area managers for each county. This decentralization of the loan underwriting
process allows loan officers and branch managers to respond more quickly to
applicants, and better serve its customers. The Company also benefits from this
decentralization in that every branch manager is well trained to originate all
types of loans, again allowing the branches to better serve their customers and
cross-sell the Company's loan products.

         Branch managers have the authority to approve loans which meet the
underwriting criteria set by management up to $120,000, and area managers have
authority for amounts up to $300,000. Any loan over $300,000 must be submitted
for approval by senior management.

         INCOME FROM LENDING ACTIVITIES. The Company earns interest and fee
income from its lending activities. The Company earns income from fees for
originating loans and for making commitments to originate loans and loan
participations. Certain of these fees net of origination costs are amortized
over the life of the respective loan. The Company also receives loan fees
related to existing loans, which include late charges. Income from loan
origination and commitment fees and discounts varies with the volume and type of
loans and commitments made and with competitive and economic conditions.

NONPERFORMING LOANS

         GENERAL. Late charges on residential mortgages are assessed by the
Company if a payment is not received either by the 10th day following its due
date or 15th day if the loan has been sold in the secondary market and is being
serviced by the Company. Late charges on installment loans and commercial loans
are assessed by the Company if a payment is not received by the 10th day
following its due date. Any borrower whose payment was not received by this time
is mailed a past due notice. If the loan is still delinquent after a second past
due notice is mailed (generally around the 20th day of delinquency), a branch
employee will attempt to contact the customer to resolve any problem that might
exist.

         When an advanced stage of delinquency appears (generally around the
60th day of delinquency) and if repayment cannot be expected within a reasonable
amount of time or a repayment agreement has not been entered into, the Bank will
contact an attorney and request that the required 30-day prior notice of
foreclosure or repossession proceedings be prepared and delivered to the
borrower so that, if necessary, foreclosure proceedings may be initiated shortly
after the loan is 90 days delinquent. This procedure has historically aided in
achieving a low level of nonperforming loans and, as of March 31, 1997, only
$852,000 or .43% of the Bank's total loan portfolio was 90 days or more past
due. As of March 31, 1997, the Company's level of nonperforming assets to total
assets was .32%.

         If a credit card account becomes 10 days delinquent, a notice is sent
to the account holder demanding that the payment be made so that the card is
current. Another notice is sent to the cardholder if the account becomes 20 days
delinquent. If payment is not received within 30 days, authorization requests
are denied, a message appears on the cardholder's account statement and a
follow-up telephone call is made. These telephone collection efforts and
statement messages continue until the account is deemed uncollectible. Legal
action is considered during this time. As of March 31, 1997, approximately
$18,000 in outstanding balances, or 1.7% of credit card loans were
nonperforming.



                                      -34-
<PAGE>   44
         On March 31, 1997, the Bank held no real estate and other repossessed
collateral acquired as a result of foreclosure, voluntary deed, or other means.
When the Bank has such real estate, it is classified as "other real estate
owned" until it is sold. When property is so acquired, it is recorded at the
lower of cost (the unpaid principal balance at the date of acquisition plus
foreclosure and other related costs) or fair value less estimated selling
expenses. Any subsequent write-down resulting therefrom is charged to expense.
Generally, unless the property is a one- to four-family residential dwelling and
well-collateralized, interest accrual ceases in 90 days but no later than the
date of acquisition. All costs incurred from that date in maintaining the
property are expensed. Other real estate owned is appraised during the
foreclosure process prior to the time of acquisition, and losses are recognized
for the amount by which the book value of the related mortgage loan exceeds the
estimated net realizable value of the property.

         Not categorized as nonperforming loans are certain potential problem
loans that management believes are adequately secured and for which no material
loss is expected, but as to which certain circumstances may cause the borrowers
to be unable to comply with the present loan repayment terms at some future
date. At March 31, 1997 there were no such potential problem loans.

         The following is a summary of the Company's loan loss experience and
selected ratios for the periods presented.

         At March 31, 1997, December 31, 1996, 1995 and 1994 the Company had
nonaccrual loans totaling $713,000, $698,000, $39,000, and $174,000,
respectively. Interest income that would have been recognized if such loans had
performed in accordance with contractual terms totaled approximately $19,000 for
the three months ended March 31, 1997, and $62,000, $1,000, and $15,000
respectively, for the years ended December 31, 1996, 1995 and 1994. There was no
interest income recognized on such loans during any of the periods.

         ALLOWANCE FOR LOAN LOSSES. The amount of the allowance for loan losses
is based on management's analysis of risks inherent in the various segments of
the loan portfolio, management's assessment of known or potential problem
credits which have come to management's attention during the ongoing analysis of
credit quality, historical loss experience, current and anticipated economic
conditions and other factors. If actual circumstances and losses differ
substantially from management's assumptions and estimates, such allowance for
loan losses may not be sufficient to absorb all future losses, and net earnings
could be adversely affected. Loan loss estimates are reviewed periodically, and
adjustments, if any, are reported in earnings in the period in which they become
known. In addition, the Company maintains a portion of the allowance to cover
potential losses inherent in the portfolio which have not been specifically
identified.

         Although management believes that it uses the best information
available to make such determinations and that the allowance for loan losses is
adequate at March 31, 1997, future adjustments to the allowance may be
necessary, and net earnings could be affected, if circumstances and/or economic
conditions differ substantially from the assumptions used in making the initial
determinations. A downturn in the Southeastern Ohio economy and employment
levels could result in the Company experiencing increased levels of
nonperforming assets and charge-offs, increased provisions for loan losses and
reductions in income. Additionally, various regulatory agencies, as an integral
part of their examination process, periodically review the Company's allowance
for loan losses. Such agencies may require the recognition of additions to the
allowance based on their judgment of information available to them at the time
of their examination.

         The following table summarizes nonperforming assets by category.

(1)      Represents accruing loans delinquent greater than 90 days which are
         considered by management to be well secured and in the process of
         collection.

         As of March 31, 1997 the Company had no loans that were not included in
the nonaccrual, past due 90 days or more or restructured categories where the
borrowers were experiencing potential credit problems that raised doubts as to
the ability of the borrowers to comply with the present loan repayment terms.

         CLASSIFIED ASSETS. The FDIC regulations on classification of assets
require commercial banks to classify their own assets and to establish
appropriate general and specific allowances for losses, subject to FDIC review.
These regulations are designed to encourage management to evaluate assets on a
case-by-case basis and to discourage automatic classifications. Assets
classified as substandard or doubtful must be evaluated by management to
determine a reasonable general loss reserve which is included in total capital
for purposes of the bank's risk-based capital requirement, but which is not
included in core capital or tangible capital or in capital under generally
accepted accounting principles. Assets classified as loss must either be written
off or reserved for by a specific allowance which is not counted toward capital
for purposes of any of the regulatory capital requirements.

         INVESTMENTS. Investment securities primarily satisfy the Company's
liquidity needs and provide a return on residual funds after lending activities.
Pursuant to the Company's written investment policy, investments may be in
interest-bearing deposits, U.S. Government and agency obligations, state and
local government obligations and government-guaranteed mortgage-backed
securities. The Company does not make any investments in securities which


                                      -36-
<PAGE>   46
are rated less than investment grade by a nationally recognized statistical
rating organization. A goal of the Company's investment policy is to limit
interest rate risk wherever possible.

         All securities-related activity is reported to the Board. General
changes in investment strategy are required to be reviewed and approved by the
Board. The Company's senior management can purchase and sell securities on
behalf of the Company in accordance with the Company's stated investment policy.

         DEPOSIT ACCOUNTS. Savings deposits are a major source of the Company's
funds. The Company offers a number of alternatives for depositors designed to
attract both commercial and regular consumer checking and savings including
regular and money market savings accounts, NOW accounts, and a variety of
fixed-maturity, fixed-rate certificates with maturities ranging from seven days
to 120 months. The Company also provides travelers' checks, official checks,
money orders, ATM services and IRA accounts.

         Effective January 16, 1995, the Company began offering a large balance
deposit account product known as the Premium Investment Account. The account is
a money market deposit account under applicable FDIC insurance regulations; it
pays an adjustable (quarterly) interest rate equal to a 13-week treasury bill
rate; there is no minimum or maximum interest rate. A minimum balance of $10,000
is required to open the account. Interest is earned on the account only so long
as the balance is greater than $5,000.

         The distribution of the Company's deposit accounts by type and rate is
set forth in the following table.

         BORROWINGS. Deposits and repayment of loan principal are the primary
source of funds for the Company's lending activities and other general business
purposes. However, during periods when the supply of lendable funds cannot meet
the demand for loans, the Company can obtain funds necessary through loans
(advances) from the FHLB of Cincinnati. Advances from the FHLB may be on a
secured or unsecured basis depending upon a number of factors, including the
purpose for which the funds are being borrowed and existing advances
outstanding. The Company typically only utilizes FHLB advances to fund long-term
fixed rate commercial loans. As of March 31, 1997, the Bank had outstanding FHLB
advances totaling $10.9 million. See Note F to the consolidated financial
statements for additional information regarding FHLB advances. The Company also
has arrangements to borrow funds from commercial banks. The Company does not
solicit brokered deposits.

         The following table sets forth the maximum amount of the Company's FHLB
advances and other borrowings outstanding at any month end during the periods
shown and the average aggregate balances of FHLB advances and other borrowings
for such periods:

PERSONNEL

         At March 31, 1997, the Company and its subsidiary employed 99 persons
on a full-time basis and 30 persons on a part-time basis.

EXECUTIVE OFFICES

         The Company's executive office is located at 14621 State Route 93,
Jackson, Ohio 45640 and its telephone number is (614) 286-3283.

SUBSIDIARY

         The Company owns all of the outstanding stock of Oak Hill Banks, an
Ohio state-chartered bank, which was founded in 1902.

REGULATION

         The Bank as an Ohio state-chartered bank, is subject to supervision and
regular examination by the Superintendent of Financial Institutions of the State
of Ohio. It is insured by the FDIC and is subject to the provisions of the
Federal Deposit Insurance Act. To the extent that the information below consists
of summaries of certain statutes or regulations it is qualified in its entirety
by reference to the statutory or regulatory provisions described.

         The Company is subject to the provisions of the Bank Holding Company
Act of 1956, as amended (the "Act"), which requires a bank holding company to
register under the Act and to be subject to supervision and examination by the
Board of Governors of the Federal Reserve System. As a bank holding company, the
Company is required to file with the Board of Governors an annual report and
such additional information as the Board of Governors may require pursuant to
the Act. The Act requires prior approval by the Board of Governors of the
acquisition by a bank holding company, or any subsidiary thereof, of 5% or more
of the voting stock or substantially all the assets of any bank within the
United States.

         As a bank holding company located in the State of Ohio, the Company is
not permitted to acquire a bank or other financial institution located in
another state unless such acquisition is specifically authorized by the statutes
of such state. The Act further provides that the Board of Governors shall not
approve any such acquisition that would result in a monopoly or would be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the business of banking in any part of the United States, or the
effect of which may be to substantially lessen competition or to create a
monopoly in any section of the country, or that in any other manner would be in
restraint of trade, unless the anti-competitive effects of the proposed
transaction are clearly outweighed in the public interest by the probable effect
of the transaction in meeting the convenience and needs of the community to be
served.

         The Act also prohibits a bank holding company, with certain exceptions,
from acquiring 5% or more of the voting stock of any company that is not a bank
and from engaging in any business other than banking or performing services for
its banking subsidiary without the approval of the Board of Governors. In
addition, the acquisition of a thrift institution must be approved by the Office
of Thrift Supervision pursuant to the savings and loan holding company
provisions of the Home Owners' Loan Act of 1933, as amended by FIRREA. The Board
of Governors is also authorized to approve, among other things, the ownership of
shares by a bank holding company in any company the activities of which the
Board of Governors has determined to be so closely related to banking or
managing or controlling banks as to be a proper incident thereto. The Board of
Governors has, by regulation, determined that certain activities, including
mortgage banking, operating small loan companies, factoring, furnishing certain
data processing operations, holding or operating properties used by banking
subsidiaries or acquired for such future use, providing certain investment and
financial advice, leasing (subject to certain conditions) real or personal
property, providing management consulting advice to certain depository
institutions, providing securities brokerage services, arranging commercial real
estate equity financing, underwriting and dealing in government obligations and
money market instruments, providing consumer financial counseling, operating a
collection agency, owning and operating a savings association, operating a
credit bureau and conducting certain real estate investment activities and
acting as insurance agent for certain types of insurance, are closely related to
banking within the meaning of the Act. It also has determined that certain other
activities, including real estate brokerage and syndication, land development,
and property management are not related to credit transactions and are not
permissible. The Act and the regulations of the Board of Governors prohibit a
bank holding company and



                                      -40-
<PAGE>   50
its subsidiaries from engaging in certain tie-in arrangements in connection with
any extension of credit, lease or sale of property, or furnishing of services.
The Act also imposes certain restrictions upon dealing by affiliated banks with
the holding company and among themselves including restrictions on interbank
borrowing and upon dealings in respect to the securities or obligations of the
holding company or other affiliates.

         The earnings of banks, and therefore the earnings of the Company (and
the Bank), are affected by the policies of regulatory authorities, including the
Board of Governors of the Federal Reserve System. An important function of the
Federal Reserve Board is to regulate the national supply of bank credit in an
effort to prevent recession and to restrain inflation. Among the procedures used
to implement these objectives are open market operations in U.S. Government
securities, changes in the discount rate on member bank borrowings, and changes
in reserve requirements against member bank deposits. These procedures are used
in varying combinations to influence overall growth and distribution of bank
loans, investments and deposits, and their use also may affect interest rates
charged on loans or paid for deposits. Monetary policies of the Federal Reserve
Board have had a significant effect on the operating results of commercial banks
in the past and are expected to continue to do so in the future. The effect, if
any, of such policies upon the future business and earnings of the Company
cannot accurately be predicted. The Company makes no attempt to predict the
effect on its revenues and earnings of changes in general economic, industrial,
and international conditions or in legislation and governmental regulations.

PROPERTIES.
        
         The registrant and its subsidiary operate from 13 offices in Ohio,
including the Company's executive office in Jackson, Ohio. Four of the offices
are located in Jackson County, Ohio. The properties in Jackson County are
located on real estate which is owned by the Company. Three offices are located
in Ross County, Ohio; one in Warren County, Ohio; three in Scioto County, Ohio;
one in Pickaway County, Ohio; one in Butler County, Ohio. Four of the offices
(located in Ross County, Butler County and Scioto County) are on leased
locations. All leases are comparable to other leases in the respective market
areas and do not contain provisions detrimental to the registrant or its
subsidiary.

LEGAL PROCEEDINGS.

         Except for routine litigation incident to their business, the
registrant and its subsidiary are not a party to any material pending legal
proceedings and none of their property is the subject of any such proceedings.

CERTAIN TRANSACTIONS

         Some of the officers and directors of the Company and the companies
with which they are associated were customers of the Bank. The loans to such
officers and directors (a) were made in the ordinary course of business, (b)
were made on substantially the same terms, including interest and nature of
collateral, as those prevailing at the time for comparable transactions with
other persons, and (c) did not involve more than the normal risk of
collectibility or present other unfavorable features.

         The Bank has had, and expects to have in the future, banking
transactions in the ordinary course of business with directors, officers,
principal shareholders, and their associates on the same terms, including
interest rates and collateral on loans, as those prevailing at the same time for
comparable transactions with others.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS.

         OVERVIEW OF YEAR END RESULTS. The principal asset of the Company is its
ownership of the Bank. Accordingly, the Company's results of operations are
primarily dependent upon the results of operations of the Bank. The Bank
conducts a general commercial banking business that consists of attracting
deposits from the general public and using those funds to originate loans for
commercial, consumer, and residential purposes.

         The Bank's profitability depends primarily on its net interest income,
which is the difference between interest income generated from interest-earning
assets (i.e., loans and investments) less the interest expense incurred on
interest-bearing liabilities (i.e., deposits and borrowed funds). Net interest
income is affected by the relative amounts of interest-earning assets and
interest-bearing liabilities, and the interest rates paid on these balances.

         Additionally, and to a lesser extent, the Bank's profitability is
affected by such factors as the level of non-interest income and expenses, the
provision for loan losses, and the effective tax rate. Non-interest income
consists primarily of service charges and other fees and income from the sale of
loans. Non-interest expenses consist of compensation and benefits,
occupancy-related expenses, FDIC deposit insurance premiums, and other operating
expenses.

         Management's discussion and analysis of earnings and related financial
data are presented herein to assist investors in understanding the consolidated
financial condition and results of operations of the Company as of and for the
years ended December 31, 1996 and 1995. This discussion should be read in
conjunction with the consolidated financial statements and related footnotes
presented elsewhere in this registration statement.

         Forward-Looking Statements. In the following pages, management presents
an analysis of the Company's financial condition as of December 31, 1996, and
the results of operations for the year ended December 31, 1996 as compared to
prior periods. The management also presents the Company's financial condition as
of March 31, 1997 and the results of operations for the three months ended March
31, 1997. In addition to this historical information, the following discussion
contains forward-looking statements that involve risks and uncertainties.
Economic circumstances, the Company's operations and the Company's actual
results could differ significantly from those discussed in the forward-looking
statements. Some of the factors that could cause or contribute to such
differences are discussed herein but also include changes in the economy and
interest rates in the nation and in the Company's general market area.

         Without limiting the foregoing, some of the forward-looking statements
include the following:

         Management's establishment of an allowance for loan losses, and its
statements regarding the adequacy of such allowance for loan losses.
Management's belief that the allowance for loan losses is adequate.

CHANGES IN FINANCIAL CONDITION FOR YEAR ENDED DECEMBER 31, 1996

         The Company's total assets amounted to $246.9 million as of December
31, 1996, an increase of $36.6 million, or 17.4%, over the $210.3 million total
at December 31, 1995. The increase was funded primarily through growth in
deposits of $27.7 million, an increase in borrowings of $6.2 million, and an
increase in stockholders' equity of approximately $2.5 million.

         Cash and due from banks, federal funds sold, and investment securities
increased by $2.3 million, or 4.9%, to a total of $49.0 million at December 31,
1996, compared to $46.7 million at December 31, 1995. Investment securities
increased by $7.6 million, as purchases of $26.6 million exceeded maturities of
$14.6 million and sales of $3.1 million, while Federal funds sold decreased by
$6.4 million during 1996.

         Loans receivable totaled $190.5 million at December 31, 1996, an
increase of $32.7 million, or 20.8%, over the $157.8 million total at December
31, 1995. Loan disbursements totaled $89.8 million during 1996, which were
partially offset by loans sales of $7.8 million and principal repayments of
$48.3 million. Loan origination volume during 1996 exceeded that of 1995 by
$17.7 million and sales volume increased by $1.5 million. The Company's
allowance for loan losses amounted to $2.6 million at December 31, 1996, an
increase of $508,000, or 23.9%, over the total at December 31, 1995. The
allowance for loan losses represented 1.36% of the total loan portfolio at
December 31, 1996, as compared to 1.33% at December 31, 1995. The Company's
allowance represented 326.2% and 189.3% of nonperforming loans, which totaled
$808,000 and $1.1 million at December 31, 1996 and 1995, respectively.

         Deposits totaled $209.6 million at December 31, 1996, an increase of
$27.7 million, or 15.2%, over the $181.9 million total at December 31, 1995. The
increase resulted from management's continuing marketing efforts, increased
customer acceptance of the Bank's "premium investment" account, and continued
growth at newer branch facilities.

         The Company's stockholders' equity amounted to $23.0 million at
December 31, 1996, an increase of $2.5 million, or 12.4%, over the balance at
December 31, 1995. The increase resulted primarily from net earnings of $3.2
million which were partially offset by dividends to stockholders of $604,000.


                                      -46-
<PAGE>   56
         SUMMARY OF EARNINGS. The table on page 53 shows for each category of
interest-earning assets and interest-bearing liabilities, the average amount
outstanding, the interest earned or paid on such amount, and the average rate
earned or paid for the years ended December 31, 1996, 1995, and 1994. The table
also shows the average rate earned on all interest-earning assets, the average
rate paid on all interest-bearing liabilities, the interest rate spread, and the
net interest margin for the same periods.

         Changes in net interest income are attributed to either changes in
average balances (volume change) or changes in average rates (rate change) for
interest-earning assets and interest-bearing liabilities. Volume change is
calculated as change in volume times the old rate, while rate change is the
change in rate times the old volume. The table on page 54 indicates the dollar
amount of the change attributable to each factor. The rate/volume change, the
change in rate times the change in volume, is allocated between the volume
change and rate change at the ratio each of the components bears to the absolute
value of their total.

DISCUSSION OF FINANCIAL CONDITION CHANGES FROM DECEMBER 31, 1996 TO MARCH 31,
1997

         At March 31, 1997, the Company had total assets of $262.8 million, an
increase of approximately $15.9 million, or 6.4%, over December 31, 1996 levels.
The increase in total assets was funded primarily by growth in the deposit
portfolio of $17.6 million and undistributed net earnings of $728,000, which
were partially offset by a decrease in Federal Home Loan Bank advances of $2.8
million.

         Cash, federal funds sold and investment securities totaled $58.0
million at March 31, 1997, an increase of $9.0 million, or 18.4%, over December
31, 1996 levels. During the three months ended March 31, 1997, management
purchased $11.9 million of investment securities, while $3.0 million of
securities matured. Securities purchased consisted primarily of U.S. treasury
notes and U.S. government agency securities. The increase reflects management's
efforts to maintain adequate levels of liquidity while maximizing yield on
short-term investments.

         Loans receivable and loans held for sale totaled $197.1 million at
March 31, 1997, an increase of $6.6 million, or 3.5%, over the total at December
31, 1996. Loan disbursements totaled approximately $41.2 million during the 1997
three month period, while principal repayments and sales amounted to $32.8
million and $1.7 million, respectively. Loan disbursements increased by $20.6
million, or 100.3%, during the 1997 period, is compared to the comparable period
in 1996. Loans originated in 1997 were primarily comprised of commercial loans,
1-4 family loans and residential loans.

         The Company's allowance for loan losses amounted to $2.7 million at
March 31, 1997, an increase of $91,000 or 3.5% over the total at December 31,
1996. The allowance for loan losses represented 1.36% and 1.37% of the total
loan portfolio at March 31, 1997 and December 31, 1996, respectively. The
Company's allowance represented 320.1% and 326.2% of non-performing loans, which
totaled $852,000 and $808,000 at March 31, 1997 and December 31, 1996,
respectively.

         The deposit portfolio totaled $227.2 million at March 31, 1997, an
increase of $17.6 million, or 8.4%, over December 31, 1996 levels. The increase
resulted from management's marketing efforts and continued growth at newer
branch facilities.

         The Bank is required to maintain minimum regulatory capital pursuant to
federal regulations. At March 31, 1997, the Bank's regulatory capital
substantially exceeded all regulatory capital requirements.


COMPARISON OF RESULTS OF OPERATIONS FOR THE THREE MONTH PERIODS ENDED MARCH 31,
1997 AND 1996

         GENERAL. Net earnings for the three months ended March 31, 1997 totaled
$900,000, an increase of $126,000, or 16.3%, over the $774,000 in net earnings
reported in the comparable 1996 period. The increase in earnings in the 1997
period is primarily attributable to a $394,000 increase in net interest income
after provision for losses on loans, which was partially offset by a $170,000
increase in general, administrative and other expenses and an increase in
federal income tax provision of $100,000.

         NET INTEREST INCOME. Total interest income for the three months ended
March 31, 1997 increased by $664,000, or 14.6%, generally reflecting the effects
of growth in interest-earning assets from $212.9 million to $251.5 million for
the three month periods ending March 31, 1996 and 1997, respectively, which was
partially offset by a decrease in the weighted-average yield year-to-year.
Similarly, total interest expense increased for the three months ended March 31,
1997 by $327,000 or 15.0%, primarily reflecting the growth in interest-bearing
liabilities from $181.3 million to $214.8 million year-to-date, which was
partially offset by a decrease in the weighted-average cost of funds from 1996
to 1997.

         PROVISION FOR LOSSES ON LOANS. The provision for losses on loans
totaled $81,000 for the three months ended March 31, 1997, a decrease of $57,000
from the comparable 1996 period. The decrease in the provision for 1997 was
primarily attributable to net charge-offs of $77,000 for the three months ended
March 31, 1996, compared to net recoveries of approximately $10,000 for the same
period ending March 31, 1997. The provision was primarily attributable to growth
in the portfolio year-to-year.

         Although management believes that it uses the best information
available in providing for possible loan losses and believes that the allowance
is adequate at March 31, 1997, future adjustments to the allowance could be
necessary and net earnings could be affected if circumstances and/or economic
conditions differ substantially from the assumptions used in making the initial
determinations.

         GENERAL, ADMINISTRATIVE AND OTHER EXPENSE. General, administrative and
other expense increased for the three months ended March 31, 1997 by $170,000,
or 11.9%. The increase was due primarily to a $69,000, or 8.8%, increase in
employee compensation and benefits, a $54,000, or 24.4%, increase in occupancy
and equipment expense, and an increase in federal deposit insurance premiums and
franchise taxes of $12,000 and $8,000, respectively. Other operating expenses
also increased year-to-year by $27,000 or 8.0%.

         The increase in employee compensation and benefits is due primarily to
normal merit increases and the employment of additional staff for a new banking
office which opened during the first quarter, which were partially offset by an
increase in deferred costs related to greater lending volume year-to-year. The
increase in franchise taxes resulted from greater levels of stockholders' equity
in 1996. The increase in federal deposit insurance premiums resulted primarily
from an increase in premium rates assessed in 1997. Other operating expenses
increased due primarily to the opening of a new branch facility during the first
quarter of 1997.

         FEDERAL INCOME TAXES. The provision for federal income taxes increased
by $100,000, or 28.9%, during the three months ended March 31, 1997, as compared
to the same period in 1996. The effective tax rates for the three month periods
ended March 31, 1997 and 1996 were 33.1% and 30.9%, respectively.

         SUBSEQUENT EVENT. On April 29, 1997, the Company announced the signing
of a definitive agreement for the acquisition of Unity. Under terms of the
agreement, the Company will exchange 8.5 shares of its common stock for each of
the 93,250 shares of Unity stock, resulting in a transaction valued at
approximately $11.7 million. The combination will be accounted for as a pooling
of interests. At March 31, 1997, Unity reported total assets of $65.1 million,
total deposits of $48.1 million and stockholders equity of $7.5 million. The
transaction is expected to be consummated during the third quarter of 1997,
subject to the approval of both the Company's and Unity's shareholders and
subject to regulatory approval.


COMPARISON OF RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1996 AND
1995

         GENERAL. Net earnings for the year ended December 31, 1996 totaled $3.2
million, an increase of $959,000, or 42.6%, over the $2.3 million in net
earnings recorded in 1995. The increase in earnings resulted primarily from a
$2.1 million increase in net interest income and a $288,000 increase in other
income, which were partially offset by a $332,000 increase in the provision for
losses on loans, a $694,000 increase in general, administrative and other
expense and a $385,000 increase in the provision for federal income taxes.

         NET INTEREST INCOME. Total interest income for the year ended December
31, 1996, amounted to $19.2 million, an increase of $2.7 million, or 16.2%, over
the $16.5 million recorded for 1995. Interest income on loans totaled $16.3
million, an increase of $2.5 million, or 18.3%, over the 1995 period. This
increase resulted primarily from a $19.1 million, or 12.8%, increase in the
average portfolio balance outstanding year-to-year, coupled with a 45 basis
point increase in the average yield, from 9.26% in 1995 to 9.71% in 1996.
Interest income on investment securities and other interest-earning assets
increased by $147,000, or 5.4%, to a total of $2.9 million in 1996, as compared
to $2.7 million in 1995. This increase resulted primarily from a $2.3 million
increase in the average portfolio balance year-to-year, combined with a 3 basis
point increase in the average yield, from 5.72% in 1995 to 5.75% in 1996.

         Total interest expense amounted to $8.9 million for the year ended
December 31, 1996, an increase of $595,000, or 7.2%, over the $8.3 million
recorded in 1995. Interest expense on deposits increased by $463,000, or 6.1%,
to a total of $8.1 million in 1996. The increase resulted primarily from a $15.5
million, or 9.8%, increase in the average deposit portfolio balance outstanding
year-to-year, which was partially offset by a 15 basis point decrease in the
average cost of deposits, from 4.79% in 1995 to 4.64% in 1996. Interest expense
on borrowings increased by $132,000, or 20.2% during 1996. This increase was due
to a $4.0 million increase in average borrowings outstanding, which was
partially offset by a 194 basis point decrease in the average cost of
borrowings, from 8.79% in 1995 to 6.85% in 1996.

         As a result of the foregoing changes in interest income and interest
expense, net interest income increased by $2.1 million, or 25.3%, for the year
ended December 31, 1996, as compared to 1995. The interest rate spread increased
by 61 basis points to 4.04% in 1996 from 3.43% in 1995, while the net interest
margin increased by 55 basis points to 4.74% in 1996 from 4.19% in 1995.

         PROVISIONS FOR LOAN LOSSES. The provision for loan losses represents a
charge to earnings to maintain the allowance at a level management believes is
adequate to absorb losses in the loan portfolio. The Company's provision for
loan losses amounted to $760,000 for the year ended December 31, 1996, as
compared to $428,000 for the same period in 1995, an increase of $332,000, or
77.6%. The provision for loan losses in 1996 was increased primarily as a result
of the $32.7 million of growth in the loan portfolio over the year. Net loan
charge-offs amounted to $252,000 in 1996, as compared to $197,000 in 1995.

         Although management believes that it uses the best information
available in providing for possible loan losses and believes that the allowance
is adequate at December 31, 1996, future adjustments to the allowance could be
necessary and net earnings could be affected if circumstances and/or economic
conditions differ substantially from the assumptions used in making the initial
determinations.

         OTHER INCOME. Other income totaled $1.2 million for the year ended
December 31, 1996, an increase of $288,000, or 31.5%, over the $915,000 in other
income recorded in 1995. The increase resulted primarily from a


                                      -48-
<PAGE>   58
$134,000, or 13.9%, increase in service fees, charges, and other operating
income, coupled with a $28,000 increase in gain on sale of loans, as well as a
$126,000 increase in net gains on securities transactions, to $17,000 during
1996 as compared to the $109,000 net loss on such sales recorded during the 1995
period. The increase in service fees, charges, and other operating income
resulted primarily from growth in the deposit portfolio, coupled with an
increase in service fee rates and management's continued focus on collecting
fees assessed on deposit accounts.

         GENERAL, ADMINISTRATIVE AND OTHER EXPENSE. General, administrative, and
other expense totaled $6.0 million for the year ended December 31, 1996, an
increase of $694,000, or 13.1%, over the $5.3 million recorded in 1995. The
increase resulted primarily from a $365,000, or 12.4%, increase in employee
compensation and benefits, a $110,000, or 14.5%, increase in occupancy and
equipment, a $40,000, or 17.0% increase in franchise taxes, and a $368,000, or
31.1% increase in other operating expense, which were partially offset by a
$189,000, or 99.0% decrease in federal deposit insurance premiums.

         The increase in employee compensation and benefits resulted primarily
from increased staffing levels required as a result of the opening of a new
branch office in Portsmouth, Ohio late in fiscal 1995 and an additional branch
facility in Circleville, Ohio which opened for business during 1996.
Additionally, the opening of such branch facilities as described above was
primarily responsible for the increase in occupancy and equipment expense. The
increase in franchise taxes resulted from the Company's continued growth in
equity during 1996. The increase in other operating expense resulted primarily
from costs attendant to the reporting requirements of a public stock company,
coupled with an increase in expense related to administration of the Bank's
credit card loan portfolio, computer software expenses associated with updating
the Bank's processing systems, as well as increases in expenses related to the
Company's overall growth year-to-year.

         FEDERAL INCOME TAXES. The provision for federal income taxes amounted
to $1.5 million for the year ended December 31, 1996, an increase of $385,000,
or 33.1%, over the $1.2 million recorded in 1995. The increase resulted
primarily from a $1.3 million, or 39.4%, increase in earnings before taxes. The
effective tax rates were 32.5% and 34.1% for the years ended December 31, 1996
and 1995, respectively.


COMPARISON OF RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1995 AND
1994

         GENERAL. Net earnings for the year ended December 31, 1995, totaled
$2.3 million, an increase of $386,000, or 20.7%, over the $1.9 million in net
earnings recorded in 1994. The increase in earnings resulted primarily from a
$647,000 increase in net interest income and a $211,000 increase in other
income, which were partially offset by a $159,000 increase in the provision for
losses on loans, a $70,000 increase in general, administrative, and other
expense and a $243,000 increase in the provision for federal income taxes.

         NET INTEREST INCOME. Total interest income for the year ended December
31, 1995, amounted to $16.5 million, an increase of $3.2 million, or 24.4%, over
the $13.3 million recorded for 1994. Interest income on loans totaled $13.8
million, an increase of $2.7 million, or 24.4%, over the 1995 period. This
increase resulted primarily from a $19.7 million, or 15.2%, increase in the
average portfolio balance outstanding year-to-year, coupled with a 69 basis
point increase in the average yield, from 8.56% in 1994 to 9.25% in 1995.
Interest income on investment securities and other interest-earning assets
increased by $533,000, or 24.5%, to a total of $2.7 million in 1995, as compared
to $2.2 million in 1994. This increase resulted primarily from a $7.1 million
increase in the average portfolio balance outstanding year-to-year.

         Total interest expense amounted to $8.3 million for the year ended
December 31, 1995, an increase of $2.6 million, or 45.7%, over the $5.7 million
recorded in 1994. Interest expense on deposits increased by $2.3 million, or
42.5%, to a total of $7.6 million in 1995. The increase resulted primarily from
a $15.1 million, or 10.5%, increase in the average deposit portfolio balance
outstanding year-to-year, coupled with a 108 basis point increase in the average
cost of deposits, from 3.71% in 1994 to 4.79% in 1995. Interest expense on
borrowings increased by $322,000, or 97.3%, during 1995. This increase was due
primarily to a $4.3 million increase in average borrowings outstanding.

         As a result of the foregoing changes in interest income and interest
expense, net interest income increased by $647,000, or 8.5%, for the year ended
December 31, 1995, as compared to 1994. The interest rate spread decreased by 53
basis points to 3.43% in 1995 from 3.96% in 1994, while the net interest margin
decreased by 28 basis points to 4.19% in 1995 from 4.47% in 1994.

         PROVISION FOR LOAN LOSSES. The Company's provision for loan losses in
1995 and 1994 was heavily influenced by the $20.2 million of growth in loans
over that period. The provision for loan losses totaled $428,000 in 1995,
compared to $269,000 in 1994. Net charge-offs totaled less than 0.2% of the
portfolio in each year.

         OTHER INCOME. Other income totaled $915,000 for the year ended December
31, 1995, an increase of $211,000, or 30.0%, over the $704,000 in other income
recorded in 1994. The increase resulted primarily from a $211,000, or 27.9%,
increase in service fees, charges, and other operating income, coupled with a
$29,000 increase in gain on sale of loans, which were partially offset by a
$29,000 increase in loss on sale of securities. The increase in service fees,
charges, and other operating income resulted primarily from growth in the
deposit portfolio, coupled with an increase in service fee rates and
management's focus on collecting fees assessed on deposit accounts.

         GENERAL, ADMINISTRATIVE AND OTHER EXPENSE. General, administrative, and
other expense totaled $5.3 million for the year ended December 31, 1995, an
increase of $70,000, or 1.3%, over the $5.2 million recorded in 1994. The
increase resulted primarily from a $181,000, or 6.5%, increase in employee
compensation and benefits and a $73,000, or 10.7%, increase in occupancy and
equipment, which were partially offset by a $166,000, or 46.5%, decline in
federal deposit insurance premiums and a $46,000, or 3.7% decrease in other
operating expense.

         The increase in employee compensation and benefits resulted primarily
from the cost attendant to the Company's stock option plan, which was partially
offset by an increase in deferred loan origination cost resulting from the
increase in loan volume. The increase in occupancy and equipment resulted
primarily from the addition of a new branch location during the year. The
decline in federal deposit insurance premiums resulted from a decline in federal
insurance rates as the Bank Insurance Fund reached its required reserve level
during 1995. The decline in other operating expense resulted primarily from a
decline in charitable contributions expense, which was partially offset by
increases in expenses related to the opening of a new branch facility.

         FEDERAL INCOME TAXES. The provision for federal income taxes amounted
to $1.2 million for the year ended December 31, 1995, an increase of $243,000,
or 26.4%, over the $920,000 total recorded in 1994. The increase resulted
primarily from a $629,000, or 22.6%, increase in earnings before taxes. The
effective tax rates were 34.1% and 33.0% for the years ended December 31, 1995
and 1994, respectively.


LIQUIDITY

         Like other financial institutions, the Company must ensure that
sufficient funds are available to meet deposit withdrawals, loan commitments,
and expenses. Control of the Company's cash flow requires the anticipation of
deposit flows and loan payments. The Company's primary sources of funds are
deposits and principal and interest payments on loans. The Company uses funds
from deposit inflows and principal and interest payments on loans primarily to
originate loans, and to purchase short-term investment securities and
interest-bearing deposits.

         At March 31, 1997 and December 31, 1996, the Company had $67.1 million
and $58.3 million, respectively, of certificates of deposit maturing within one
year. It has been the Company's historic experience that such certificates of
deposit will be renewed at market rates of interest. It is management's belief
that maturing certificates of deposit over the next year will similarly be
renewed at market rates of interest without a material adverse effect on results
of operations.

         In the event that certificates of deposit cannot be renewed at
prevalent market rates, the Company can obtain up to $40.0 million in advances
from the Federal Home Loan Bank of Cincinnati (FHLB). Also, as an operational
philosophy, the Company seeks to obtain advances to help with asset/liability
management and liquidity. At March 31, 1997 and December 31, 1996, the Company
had $10.9 million and $13.6 million of outstanding FHLB advances.

         As of March 31, 1997 and December 31, 1996, loan commitments, or loans
committed but not closed, totaled $3.8 million and $3.9 million, respectively.
Additionally, the Bank had unused lines of credit and letters of credit totaling
$5.2 million and $1.2 million at March 31, 1997 and $4.8 and $1.1 million at
December 31, 1996, respectively. Funding for these amounts is expected to be
provided by the sources described above. Management believes the Company has
adequate resources to meet its normal funding requirements.


EFFECT OF RECENT ACCOUNTING PRONOUNCEMENTS

         In October 1994, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards (" SFAS") No. 119,
"Disclosure About Derivative Financial Instruments and Fair Value of Financial
Instruments." SFAS No. 119 requires financial statement disclosure of certain
derivative financial instruments, defined as futures, forwards, swaps, option
contracts, or other financial instruments with similar characteristics. In the
opinion of management, SFAS No. 119 will have no material effect on the
Company's consolidated financial condition or results of operations, as the
Company does not invest in derivative financial instruments, as defined. As a
result, the applicability of SFAS No. 119 relates solely to disclosure
requirements pertaining to fixed-rate and adjustable-rate loan commitments.

         In June 1994, the FASB issued SFAS No, 122, "Accounting for Mortgage
Servicing Rights," which requires that the Company recognize as separate assets,
rights to service mortgage loans for others, regardless of how those servicing
rights are acquired. An institution that acquires mortgage servicing rights
through either the purchase or origination of mortgage loans and sells those
loans with servicing rights retained would allocate some of the cost of the
loans to the mortgage servicing rights.

         SFAS No. 122 requires that securitizations of mortgage loans be
accounted for as sales of mortgage loans and acquisitions of mortgage-backed
securities. Additionally, SFAS No. 122 requires that capitalized mortgage
servicing rights and capitalized excess servicing receivables be assessed for
impairment. Impairment is based on fair value.

         SFAS No. 122 would be applied prospectively to fiscal years beginning
after December 15, 1995 (January 1, 1996, as to the Company) to transactions in
which an entity acquires mortgage servicing rights and to impairment evaluations
of all capitalized mortgage servicing rights and capitalized excess servicing
receivables whenever acquired. Retroactive application is prohibited. Management
adopted SFAS No. 122 effective January 1, 1996 without material effect on the
Company's consolidated financial position or results of operations.


                                      -50-
<PAGE>   60
         In October 1995, the FASB issued SFAS No. 123, "Accounting for
Stock-Based Compensation," establishing financial accounting and reporting
standards for stock-based employee compensation plans. SFAS No. 123 encourages
all entities to adopt a new method of accounting to measure compensation cost of
all employee stock compensation plans based on the estimated fair value of the
award at the date it is granted. Companies are, however, allowed to continue to
measure compensation cost for those plans using the intrinsic value based method
of accounting, which generally does not result in compensation expense
recognition for most plans. Companies that elect to remain with the existing
accounting are required to disclose in a footnote to the financial statements
pro forma net earnings and, if presented, earnings per share, as if SFAS No. 123
has been adopted. The accounting requirements of SFAS No. 123 are effective for
transactions entered into during fiscal years that begin after December 15,
1995; however, companies are required to disclose information for awards granted
in their first fiscal year beginning after December 31, 1994. Management has
determined that the Company will continue to account for stock-based
compensation pursuant to Accounting Principles Board Opinion No. 25, and
therefore SFAS No. 123 will have no effect on its consolidated financial
condition or results of operations.

         In June 1996, the FASB issued SFAS No. 125, "Accounting for Transfers
of Financial Assets, Servicing Rights, and Extinguishment of Liabilities," that
provides accounting guidance on transfers of financial assets, servicing of
financial assets, and extinguishment of liabilities. SFAS No. 125 introduces an
approach to accounting for transfers of financial assets that provides a means
of dealing with more complex transactions in which the seller disposes of only a
partial interest in the assets, retains rights or obligations, makes use of
special purpose entities in the transaction, or otherwise has continuing
involvement with the transferred assets. The new accounting method, referred to
as the financial components approach, provides that the carrying amount of the
financial assets transferred be allocated to components of the transaction based
on their relative fair values. SFAS No. 125 provides criteria for determining
whether control of assets has been relinquished and whether a sale has occurred.
If the transfer does not qualify as a sale, it is accounted for as a secured
borrowing. Transactions subject to the provisions of SFAS No. 125 include among
others, transfers involving repurchase agreements, securitizations of financial
assets, loan participations, factoring arrangements and transfers of receivables
with recourse.

         An entity that undertakes an obligation to service financial assets
recognizes either a servicing asset or liability for the servicing contract
(unless related to a securitization of assets, and all the securitized assets
are retained and classified as held-to-maturity). A servicing asset or liability
that is purchased or assumed is initially recognized at its fair value.
Servicing assets and liabilities are amortized in proportion to and over the
period of estimated net servicing income or net servicing loss and are subject
to subsequent assessments for impairment based on fair value.

         SFAS No. 125 provides that a liability is removed from the balance
sheet only if the debtor either pays the creditor and is relieved of its
obligation for the liability or is legally released from being the primary
obligor.

         SFAS No.125 is effective for transfers and servicing of financial
assets and extinguishment of liabilities occurring after December 31, 1997, and
is to be applied prospectively. Earlier or retroactive application is not
permitted. Management does not believe that adoption of SFAS No. 125 will have a
material adverse effect on the Company's consolidated financial position or
results of operations.

         In February 1997, the FASB issued SFAS No. 128 "Earnings Per Share",
which requires companies to present basic earnings per share and, if applicable,
diluted earnings per share, instead of primary and fully diluted earnings per
share, respectively. Basic earnings per share is computed without including
potential common share, i.e. no dilutive effect. Diluted earnings per share is
computed taking into consideration common shares outstanding and dilutive
potential common shares, including options, warrants, convertible securities and
contingent stock agreements. SFAS No. 128 is effective for periods ending after
December 15, 1997. Early application is not permitted. Based upon the provisions
of SFAS No. 128, the Company's basic and diluted earnings per share for three
months ended March 31, 1997 would have been $.31 and $.31, respectively.


IMPACT OF INFLATION AND CHANGING PRICES

         The consolidated financial statements and related data herein have been
prepared in accordance with generally accepted accounting principles, which
require measurement of financial condition and results of operations in terms of
historical dollars, without considering changes in the relative purchasing power
of money over time due to inflation.

         Since the primary assets and liabilities of the Company are monetary in
nature, changes in the general level of prices for goods and services have a
relatively minor impact on the Company's total expenses. Increases in operating
expenses such as salaries and maintenance are in part attributable to inflation.
However, interest rates have a far more significant effect than inflation on the
performance of financial institutions, including the Company.

As an Ohio-chartered savings bank, Unity is subject to supervision and
regulation by the FDIC and the Ohio Division of Financial Institutions. Unity is
a member of the FHLB of Cincinnati and deposits at Unity are insured up to the
applicable limits by the FDIC in the Savings Association Insurance Fund (the
"SAIF").

         Unity conducts business from its main office at 115 W. Main Street,
McArthur, Ohio and its branch offices in Gallipolis, Jackson and Wellston, Ohio.
The principal business of Unity is the origination of permanent mortgage loans
secured by first mortgages on one- to four-family residential real estate
located in Unity's primary market area, Vinton, Gallia and Jackson Counties,
Ohio. Unity also originates mortgage loans secured by multifamily real estate
and nonresidential real estate in its market area. In addition to real estate
lending, Unity originates secured and unsecured consumer loans. Funds for
lending and other investment activities are obtained primarily from savings
deposits and principal repayments on loans. Advances from the FHLB of Cincinnati
are utilized from time to time when additional funds are needed to satisfy loan
demand or to fund deposit withdrawals.

         REAL ESTATE LENDING. Unity makes permanent conventional mortgage loans
on one- to four-family residential properties, multifamily properties and
nonresidential real estate located in its primary market area, which consists of
Vinton, Gallia and Jackson Counties, Ohio. Unity originates fixed-rate and
adjustable-rate mortgage loans secured by real estate with loan-to-value ratios
("LTVs") of up to 80% of the lesser of the appraised value or the purchase price
of the property. Unity's fixed-rate loans typically have maturities of up to 15
years, although Unity occasionally originates fixed-rate mortgage loans with
terms of up to 20 years. Adjustable-rate loans originated by Unity have terms of
up to 30 years. Currently, Unity offers adjustable-rate residential mortgage
loans with adjustment periods of one year and maximum increases per adjustment
period and over the life of the loan. The adjustment limits on Unity's
adjustable-rate loans are 1% per year and 6% over the life of the loan or 2% per
year and 5% over the life of the loan. The rate


                                      -54-
<PAGE>   64
adjustments are based on the Average Contract Interest Rate for Previously
Occupied Single Family Homes, as published by the Federal Housing Finance Board.

         Multifamily lending is generally considered to involve a higher degree
of risk than single family lending because the borrower typically depends upon
income generated by the project to cover operating expenses and debt service.
The profitability of a project can be affected by economic conditions,
government policies and other factors beyond the control of the borrower. Unity
attempts to reduce the risk associated with multifamily lending by evaluating
the creditworthiness of the borrower and the project income from the project and
by obtaining personal guarantees on loans made to corporations and partnerships.

         Nonresidential real estate lending may entail significant additional
risks compared to residential mortgage lending. Such loans may involve large
loan balances to single borrowers or groups of related borrowers. In addition,
the payment experience on loans secured by income producing properties is
typically dependent on the successful operation of the properties and thus may
be subject, to a greater extent, to adverse conditions in the real estate market
or in the economy generally.

         CONSUMER LOANS. Unity offers several consumer loan products, including
loans secured by deposit accounts at Unity, home equity loans, auto, boat and
recreational vehicle loans, mobile home loans and secured and unsecured
installment loans. Secured loans are made at fixed rates of interest for terms
of up to 15 years. Unsecured loans are made to creditworthy individuals in
amounts that generally range from $300 to $5,000 at fixed rates with maturities
of up to five years.

         Loan officers underwrite installment loans and other consumer loans in
a manner designed to assure compliance with various regulations and Unity's
underwriting standards. Unity's underwriting guidelines require that a consumer
borrower's income be adequate to service all of the borrower's debts, including
the proposed loan, or an alternative acceptable means of repayment must be
available.

         At March 31, 1997, Unity had approximately $8.6 million in its consumer
loan portfolio, or 17.9% of Unity's total loans.

         LOAN SOLICITATION AND PROCESSING. Loan originations are developed from
a number of sources, including continuing business with depositors, other
borrowers and walk-in customers.

         Underwriting guidelines for all loan types are set by the Board of
Directors and reviewed each year. Loan processing and underwriting are
decentralized, with loan applications generally being processed and underwritten
at the branch where the application is taken. Loan officers and branch managers
review the applications, as well as credit bureau reports, appraisals, financial
information, verification of income, and other documents concerning the
credit-worthiness of the borrower, as applicable to each loan type.

         Branch managers and loan officers have the authority to approve loans
which meet the underwriting criteria set by the board, up to $60,000 for
mortgage loans, including home equity loans, and up to $20,000 for other types
of secured consumer loans. The President of Unity has the authority to approve
loans which meet the underwriting criteria set by the board, up to $250,000 for
mortgage loans, including home equity loans, and up to $35,000 for other types
of secured consumer loans. The Executive Committee has the authority to approve
loans, which meet the underwriting criteria set by the board, up to $250,000 for
mortgage loans, including home equity loans, and $45,000 for other types of
unsecured consumer loans.

         Interest rates charged by Unity on its loans are primarily determined
by competitive loan rates offered in its lending area and Unity's cost of funds.
These rates reflect prevailing interest rates generally, the availability of
lendable funds and the demand for loans.

         In addition to interest earned on loans, Unity earns income from fees
for originating loans. Unity also receives loan fees related to existing loans,
including late charges.

         NONPERFORMING LOANS AND CLASSIFIED ASSETS. Late charges on residential
mortgages are assessed by Unity if a payment is not received by the 15th day
following such payment's due date. Late charges on installment loans are
assessed by Unity if a payment is not received by the 10th day following its due
date. If a loan is still delinquent after


                                      -55-
<PAGE>   65
a past due notice is mailed (generally around the 19th day of delinquency), a
branch employee will attempt to contact the customer to resolve any problem that
might exist.

         When an advanced stage of delinquency occurs on a real estate loan
(generally around the 90th day of delinquency) and if repayment cannot be
expected within a reasonable amount of time or a repayment agreement has not
been entered into, Unity contacts an attorney and requests that a 30-day prior
notice of foreclosure or repossession proceedings be prepared and delivered to
the borrower so that, if necessary, foreclosure proceedings may be initiated
after the loan is 120 days delinquent. Unity has historically had a low level of
nonperforming loans. As of March 31, 1997, only $373,000 of loans were past due
or accounted for on a nonaccrual basis, and Unity had no real estate acquired
through foreclosure. At March 31, 1997, Unity's ratio of nonperforming assets to
total assets was 0.6%.

         When Unity has real estate or other repossessed collateral acquired as
a result of foreclosure, voluntary deed, or other means, it is classified as
"other real estate owned" until it is sold. When property is so acquired, it is
recorded at the lower of cost (the unpaid principal balance at the date of the
acquisition plus foreclosure and other related costs) or fair value less
estimated selling expenses. Any subsequent write-down resulting therefrom is
charged to expense. Generally, unless a loan is secured by a one- to four-family
residential dwelling and well-collateralized, interest accrual ceases when a
loan becomes 90 days past due, but no later than the date of acquisition. All
costs incurred in maintaining a property from the date of acquisition are
expensed. Other real estate owned is appraised during the foreclosure process
prior to the time of acquisition and losses are recognized for the amount by
which the book value of the related mortgage loan exceeds the estimated net
realizable value of the property.

         Certain potential problem loans that management believes are adequately
secured and for which no material loss is expected, but as to which certain
circumstances may cause the borrowers to be unable to comply with the loan
repayment terms at some future date, are not included in nonperforming loans. At
March 31, 1997, there were no such potential problem loans.

         The following table sets forth information with respect to Unity's
nonperforming loans and other nonperforming assets at the dates indicated:

         For the three months ended March 31, 1997, no interest income was
recognized on nonaccruing loans and $3,000 would have been recorded as interest
income on nonaccruing loans had such loans been accruing pursuant to contractual
terms.

         ALLOWANCE FOR LOAN LOSSES. Unity maintains an allowance with respect to
possible losses on loans. The amount of the allowance is based on past loss
experience, trends in the level of delinquent and problem loans, adverse
situations that may affect the ability of a particular borrower to repay his
loan, the estimated value of the underlying collateral and current and
anticipated economic conditions in the primary lending area. When the collection
of a specific


                                      -56-
<PAGE>   66
loan becomes doubtful or otherwise troubled, Unity records a provision equal to
the difference between the fair value of the property securing the loan and the
loan's carrying value.

         The following table sets forth an analysis of Unity's allowance for
loan losses for the periods indicated.

INVESTMENT ACTIVITIES.

         Federal regulations and Ohio law permit Unity to invest in various
types of liquid assets. The Board of Directors of Unity has adopted an
investment policy which authorizes management to make investments in U.S.
Government and agency securities, deposits in the FHLB, certificates of deposit
in federally-insured financial institutions, banker's acceptances issued by
major U.S. banks, corporate debt securities rated by a major statistical rating
firm as at least "AA," or equivalent, and municipal or other tax free
obligations. Unity's investment policy is designed primarily to provide and
maintain liquidity within regulatory guidelines, to maintain a balance of high
quality investments to minimize risk and to maximize return without sacrificing
liquidity and safety.

DEPOSITS AND BORROWINGS.

         Deposits are the major source of Unity's funds for lending and other
investment purposes. In addition to deposits, Unity derives funds from loan
principal repayments. Loan repayments are a relatively stable source of funds
while deposit inflows and outflows may be significantly influenced by general
interest rates and money market conditions. Unity also has access to advances
from the FHLB of Cincinnati. These advances can be used on a short-term basis to
compensate for reductions in the availability of funds from other sources or
they may be used on a longer-term basis for general business purposes.

         DEPOSITS. Local deposits are, and traditionally have been, the primary
source of Unity's funds for use in lending and other general business purposes.
Unity offers a number of deposit accounts, including passbook and certificate
accounts. Deposit accounts vary as to terms, with the principal differences
being the minimum balance required, the time period the funds must remain on
deposit and the interest rate. Unity reviews the interest rates offered on
various savings accounts periodically and adjusts its rates as appropriate to
remain competitive with other financial institutions in its market area.

         The following table sets forth the dollar amount of deposits in the
various types of savings programs offered by Unity at the dates indicated:

         BORROWINGS. The FHLB system functions as a central reserve bank
providing credit for its member institutions and certain other financial
institutions. As a member in good standing of the FHLB of Cincinnati, Unity is
required to own capital stock in the FHLB and is authorized to apply for
advances on the security of such stock and certain of its home mortgages and
other assets (principally securities which are obligations of, or guaranteed by,
the United States) provided certain standards related to creditworthiness have
been met. Advances are made pursuant to several different programs. Each credit
program has its own interest rate and range of maturities. Depending on the
program, limitations on the amount of advances are based either on a fixed
percentage of an association's regulatory capital or on the FHLB's assessment of
the institution's creditworthiness.

The following table sets forth certain information regarding Unity's FHLB
advances at the dates indicated:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


GENERAL

         Unity is primarily engaged in the business of attracting savings
deposits from the general public and investing such funds in mortgage loans
secured by one- to four-family residential real estate located in its primary
market area. Unity also originates loans for the construction or improvement of
one- to four-family residential real estate loans secured by multi-family
residential real estate (over four units) and nonresidential real estate and
consumer loans, and invests in U.S. Government and agency obligations,
interest-bearing deposits in other financial institutions, mortgage-backed
securities and other investments permitted by law.

         The principal determinants of Unity's net income are net interest
income and operating expenses. Net interest income is affected by the relative
amounts of interest-earning assets and interest-bearing liabilities, and the
interest rates earned or paid on these balances. To a lesser extent, Unity's
profitability is affected by such factors as the level of non-interest income
and expenses, the provision for loan losses, and the effective tax rate. Other
income consists primarily of service charges and other fees. General
administrative and other expense consists of employee compensation and benefits,
occupancy expenses, FDIC deposit insurance premiums and other operating
expenses.

         The following discussion and analysis of Unity's earnings and related
financial data should be read in conjunction with the financial statements and
related footnotes presented elsewhere in this Prospectus.

CHANGES IN FINANCIAL CONDITION

         Unity's total assets increased slightly from $65.0 million at December
31, 1996, to $65.1 million at March 31, 1997. Such growth resulted primarily
from an increase in shareholders' equity. A decrease of $253,000 in cash and
cash equivalents during the 1997 three month period was offset by a $265,000
increase in loans receivable.

         Total liabilities increased negligibly. A $956,000 increase in FHLB
advances was used to fund deposit outflows of $918,000 during the quarter.
Shareholders' equity increased $80,000 from December 31, 1996, to March 31,
1997, primarily as a result of net income of $197,000 for the quarter ended
March 31, 1997, which was partially offset by a $117,000 increase in unrealized
loss on securities available for sale.

         Total assets increased $7.0 million, or 12.0%, from December 31, 1995,
to December 31, 1996. Increases in loans receivable and investments primarily
accounted for the increase in total assets. Total liabilities increased $6.7
million, or 13.1%, primarily as a result of the increased use of FHLB advances
to fund loan originations and the purchase of investment securities.

         During 1996, cash and cash equivalents decreased $461,000, or 26.8%,
investments increased $3.8 million, or 95.1%, and loans receivable increased
$4.7 million, or 11.0%, from December 31, 1995 levels. These changes are a
result of a strategy implemented by Unity in 1996 to more effectively leverage
its capital through the use of FHLB advances and to invest the proceeds in
investment securities at a profitable spread. Increased loan demand during 1996
was funded with cash and cash equivalents and a portion of the FHLB advances.

         Deposits increased slightly from $48.8 million at December 31, 1995, to
$49.0 million at December 31, 1996. FHLB advances increased by $6.5 million, or
469.3%, as a result of the leveraging strategy described above.

         Shareholders' equity increased $310,000 from December 31, 1995, to
December 31, 1996, primarily as a result of 1996 earnings, which were offset
slightly by a small increase in unrealized loss on securities available for
sale.

COMPARISON OF RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 1996
AND 1997

         GENERAL. Unity's net income was $197,000 for the three months ended
March 31, 1997, compared to $135,000 for the three months ended March 31, 1996,
an increase of $62,000, or 45.9%. Unity's net income increased primarily as a
result of an increase in net interest income and a decline in general
administrative and other expenses, which were offset somewhat by an increase in
the provision for loan losses, a decrease in other income and an increase in
federal income taxes.

         NET INTEREST INCOME. Net interest income increased $94,000, or 18.5%,
from 1996 to 1997. An increase of $172,000 in total interest income was offset
somewhat by an increase of $78,000 in interest expense.

         Interest income on loans increased $112,000, or 11.6%, primarily as a
result of the increase in the average outstanding balance. Interest income on
mortgage-backed securities decreased $15,000, or 12.6%, primarily as a result of
a decrease in the average outstanding balance, which more than offset the
effects of the increase in average yield from 6.67% to 7.04%. Interest income on
investment securities increased $75,000, or 90.4%, primarily as a result of the
increase in the average outstanding balance.

         Interest expense, consisting of interest paid on deposits and FHLB
advances, increased $78,000, or 11.7%. Interest paid on deposits declined by
$21,000, primarily a result of the decline in the average rate from 5.30% for
the three months ended March 31, 1996, to 5.14% for the three months ended March
31, 1997. Interest expense on FHLB advances increased $99,000, or 430.4%, as a
result of the increase in the average outstanding balance, which more than
offset the effects of the decline in average rate from 7.26% to 6.04% from
period to period.

         PROVISION FOR LOAN LOSSES. The provision for loan losses increased
$4,000, or 19.0%. The increase was principally based on growth in the loan
portfolio.

          OTHER INCOME AND GENERAL, ADMINISTRATIVE AND OTHER EXPENSES. Other
income decreased $7,000, or 14.9%, from March 31, 1996, to March 31, 1997.
General, administrative and other expenses decreased $16,000, or 4.8%, during
the period, primarily as a result of a $23,000, or 85.2%, decrease in federal
deposit insurance premiums and a

                                     - 62 -
<PAGE>   72
$17,000 decrease in other operating expenses. In the fourth quarter of 1996, the
FDIC reduced SAIF premiums from approximately 23 basis points to 6.4 basis
points following the recapitalization of the SAIF. The reduction in deposit
insurance premiums and other operating expenses were offset somewhat by
increases in salaries and employee benefits, occupancy expense, state franchise
taxes, other operating expenses and outside data processing costs.

         FEDERAL INCOME TAXES. Federal income taxes for the three months ended
March 31, 1997, increased by $37,000, or 56.9%, as a result of the increase in
income before federal income tax. Unity's effective federal income tax rate was
34.1% for the 1997 period compared to 32.5% for the 1996 period.

COMPARISON OF RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1996 AND
1995

         GENERAL. Unity's net income was $503,000 for 1996, compared to $529,000
for 1995, a decrease of $26,000, or 4.9%. Despite increases in net interest
income and other income, Unity's net income decreased solely as a result of the
payment of a $309,000 special assessment in September 1996 to recapitalize the
SAIF.

         NET INTEREST INCOME. Net interest income increased $215,000, or 10.7%,
from 1995 to 1996. An increase of $395,000 in total interest income was offset
somewhat by an increase of $180,000 in total interest expense.

         Interest income on loans increased $245,000, or 6.4%, primarily as a
result of the increase in the average outstanding balance. The total increase
due to volume was offset somewhat by a decline in yield from 9.21% for 1995 to
9.13% for 1996. Interest income on mortgage-backed securities increased $11,000,
or 2.6%, primarily as a result of the increase in the average outstanding
balance. The increase due to volume was offset somewhat by a decline in yield
from 7.04% for 1995 to 6.72% for 1996. Interest income on investment securities
increased $139,000, or 46.7%, as a result of the increase in the average
outstanding balance, and an increase in yield from 6.55% for 1995 to 7.51% for
1996.

         Interest expense, consisting of interest paid on deposits and FHLB
advances, increased $180,000, or 7.0%. The $15,000 increase in interest paid on
deposits was primarily a result of the increase in the average outstanding
balance of certificates of deposit, which more than offset the effects of a
decline in average rate paid on total deposits from 5.26% for 1995 to 5.16% for
1996. Interest expense on FHLB advances increased $165,000, or 311.3%, as a
result of the increase in average outstanding balance.

         PROVISION FOR LOAN LOSSES. The provision for loan losses decreased
$54,000, or 35.3%. The decrease was based on a decline in nonperforming loans
during 1996.

         OTHER INCOME. Other income increased $14,000 primarily as a result of
an increase in the cash value of life insurance policies owned by Unity in
connection with a nonqualified retirement plan.

         GENERAL ADMINISTRATIVE AND OTHER EXPENSE. General, administrative and
other expense increased $345,000, or 27.6%, primarily as a result of a $286,000,
or 267.3%, increase in federal deposit insurance premiums. Increases in salaries
and employee benefits, state franchise taxes, other operating expenses and
outside data processing costs also contributed to the increase in other
expenses.

         FEDERAL INCOME TAXES. Federal income taxes for 1996 decreased by
$36,000, or 13.7%, as a result of the decline in income before federal income
taxes. Unity's effective federal income tax rate was 31.0% for 1996 compared to
33.1% for 1995.

COMPARISON OF RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1995 AND
1994

         GENERAL. Net income decreased $42,000, or 7.4% for the year ended
December 31, 1995 compared to 1994, primarily as a result of a decline in net
interest income and an increase in the provision for loan losses, which were
partially offset by an increase in other income and a decrease in federal income
taxes.

         NET INTEREST INCOME. Net interest income decreased $69,000, or 3.3%,
from 1994 to 1995. An increase of $349,000 in total interest income was more
than offset by an increase of $418,000 in total interest expense.

         Interest income on loans increased $281,000, or 7.9%, primarily as a
result of the increase in the average outstanding balance. Interest income on
mortgage-backed securities increased $15,000, or 3.7%, as a result of the

                                     - 63 -

increase in average yield from 6.42% to 7.04%, which more than offset the
effects of the decrease in the average outstanding balance from year to year.
Interest income on investment securities increased $53,000, or 24.9%, primarily
as a result of the increase in the average yield from 5.16% for 1994 to 6.55%
for 1995.

         Interest expense increased $418,000, or 19.5%, primarily as a result of
an increase in interest paid on deposits, which increased $393,000, or 18.6%.
The increase in interest paid on deposits was primarily a result of the increase
in the average outstanding balance of certificates of deposit and the increase
in interest paid on certificates of deposits. Although Unity experienced a
slight decline in the average rate paid on interest-bearing checking accounts
and passbook savings accounts, the average rate paid on certificates of deposit
increased from 5.22% for 1994 to 5.94% for 1995. An increase in the average
outstanding balance of certificates of deposit also contributed significantly to
the increase in interest paid on certificate accounts. During 1995, Unity
utilized a pricing strategy designed to attract longer-term certificates of
deposit in anticipation of a rising interest rate environment. Interest expense
on FHLB advances increased $25,000, or 89.3%. The increase in the average
outstanding balance and the increase in the average rate contributed equally to
the increase in interest expense on FHLB advances.

         PROVISION FOR LOAN LOSSES. The provision for loan losses increased
$59,000, or 62.8%. The increase was based on an increase in nonperforming loans
which was attributable to one loan.

         OTHER INCOME. Other income increased $64,000, or 53.3%, primarily as a
result of an increase in the cash value of life insurance policies.

         GENERAL, ADMINISTRATIVE AND OTHER EXPENSES. General, administrative and
other expenses increased $25,000, or 2.0%, primarily as a result of a $49,000,
or 8.5%, increase in salaries and employee benefits and an $11,000 increase in
state franchise taxes. These increases were offset somewhat by decreases in net
occupancy expense and other operating expenses.

         FEDERAL INCOME TAXES. Federal income taxes for 1995 decreased by
$47,000, or 15.2%, as a result of the decline in income before federal income
taxes. Unity's effective federal income tax rate was 33.1% for 1995 compared to
35.1% for 1994.

         The following table presents certain information relating to Unity's
average balance sheet information and reflects the average yield on
interest-earning assets and the average cost of interest-bearing liabilities for
the periods indicated. Such yields and costs are derived by dividing annual
income or expense by the average monthly balance of interest-earning assets or
interest-bearing liabilities, respectively, for the periods presented. Average
balances are derived from daily balances, which include nonaccruing loans in the
loan portfolio, net of the allowance for loan losses.

         The following table sets forth, for the periods indicated, the weighted
average yields earned on Unity's interest-earning assets, the weighted average
interest rates paid on interest-bearing liabilities, the interest rate spread
and the net interest margin on interest-earning assets. Such yields and costs
are derived by dividing income or expense by the average balance of assets or
liabilities, respectively, for the periods presented.

         The table below describes the extent to which changes in interest rates
and changes in volume of interest-earning assets and interest-bearing
liabilities have affected Unity's interest income and expense during the periods
indicated. For each category of interest-earning assets and interest-bearing
liabilities, information is provided on changes attributable to (i) changes in
volume (change in volume multiplied by prior year rate), (ii) changes in rate
(change in rate multiplied by prior year volume) and (iii) total changes in rate
and volume. The combined effects of changes in both volume and rate, which
cannot be separately identified, have been allocated proportionately to the
change due to volume and the change due to rate:

LIQUIDITY AND CAPITAL RESOURCES

         Unity's principal sources of funds are deposits, loan and
mortgage-backed securities repayments, maturities of securities and other funds
provided by operations. Unity also has the ability to borrow from the FHLB of
Cincinnati. While scheduled loan repayments and maturing investments are
relatively predictable, deposit flows and early loan and mortgage-backed
securities prepayments are more influenced by interest rates, general economic
conditions and competition. Unity maintains investments in liquid assets based
upon management's assessment of (i) the need for funds, (ii) expected deposit
flows, (iii) the yields available on short-term liquid assets and (iv) the
objectives of the asset/liability management program.

         Unity maintains investments in United States Treasury securities,
federal agency obligations and other investments having maturities of five years
or less to provide a source of relatively liquid funds upon which Unity may rely
if necessary to fund deposit withdrawals or other short-term funding needs. At
March 31, 1997, Unity had commitments to originate loans totaling approximately
$653,000. Unity considers its liquidity and capital reserves sufficient to meet
its outstanding short- and long-term needs. At March 31, 1997, Unity had no
material commitments for capital expenditures.

      COMPARISON OF CERTAIN RIGHTS OF SHAREHOLDERS OF THE COMPANY AND UNITY

         Each of the Company and Unity is incorporated in the State of Ohio. The
rights of Unity's shareholders are currently governed and defined by OGCL and by
the Unity Amended and Restated Articles of Incorporation (the "Unity Articles"),
and the Unity Amended Constitution (the "Unity Constitution"). Upon consummation
of the Merger, the shareholders of Unity will become shareholders of the Company
and their rights will cease to be governed and defined by the Unity Articles,
and the Unity Constitution and will be defined and governed by the Company's
Second Amended and Restated Articles of Incorporation, (the "Oak Hill
Articles"), and the Company's First Amended and Restated Code of Regulations
(the "Oak Hill Regulations"). Certain provisions of the Oak Hill Articles and
the Oak Hill Regulations provide different rights to shareholders from those
that the Unity shareholders have. Certain of these provisions are summarized
below. This summary is not intended to be complete and is qualified in its
entirety by reference to applicable provisions of the OGCL and to the respective
corporate documents of the Company and Unity. For information as to how such
corporate documents may be obtained, see "AVAILABLE INFORMATION."

CAPITAL STOCK

         The OGCL requires a corporation's articles of incorporation to set
forth the total number of shares of all classes of stock that the corporation
has authority to issue, and, for each class, the designations, powers,
preferences, rights, qualifications, limitations and restrictions thereof.

         The Oak Hill Articles currently authorize 5,000,000 shares of Oak Hill
Common Stock of which 2,873,500 shares were issued and outstanding on July __,
1997; and 1,500,000 shares of voting Oak Hill Preferred Stock, $.01 par value,
of which no shares were issued and outstanding on July __, 1997, and 1,500,000
shares of non-voting Oak Hill Preferred Stock (collectively, the 3,000,000
shares of Preferred Stock are referred to as "Oak Hill Preferred Stock"), of
which no shares were issued and outstanding on July __, 1997.

         The Unity Articles currently authorize 2,000,000 common shares, of
which 93,250 shares were issued and outstanding on July __, 1997. Unity has no
shares of preferred stock authorized.

         The provisions of the Oak Hill Articles setting the terms of the Oak
Hill Common Stock are generally the same as the comparable provisions for the
Unity Articles. Holders of Oak Hill Common Stock and Unity Common Shares are
entitled to one vote per share on all matters submitted to a vote of
stockholders, have no preemptive rights and no conversion rights, are not
subject to redemption and have no sinking fund. The Oak Hill Articles and Unity
Articles do not provide cumulative voting rights in the election of directors.

         The rights, preferences and privileges of holders of Oak Hill Common
Stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of Oak Hill Preferred Stock that the Company may
designate and issue in the future. In addition, the right of holders of Oak Hill
Common Stock to receive ratably any dividends that may be declared by the
Company's Board of Directors is subject to preferential dividend rights of any
Oak Hill Preferred Stock then outstanding. Additionally, the Company may enter
into bank credit agreements in the future which include financial covenants
restricting the payment of dividends. See "SUMMARY -- Market Price Data;
Dividend Policy."

         Although no shares of Oak Hill Preferred Stock are outstanding, the
Company's Board of Directors has the authority, without any further vote or
action by the shareholders, to issue Oak Hill Preferred Stock in one or more
classes or series and to fix the number of shares, designations, powers,
preferences, rights, qualifications, limitations and restrictions thereof. The
ability of the Company's Board of Directors to so issue Oak Hill Preferred
Stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire (or of discouraging a third party from acquiring) a
majority of the outstanding voting stock of the corporation. The Company
currently has no plans to issue any Oak Hill Preferred Stock.

VOTING POWER

         Holders of Oak Hill Common Stock and Unity Common Shares are generally
entitled to one vote per share.

PAYMENT OF DIVIDENDS AND OTHER DISTRIBUTIONS

         Holders of both Unity Common Shares and Oak Hill Common Stock are
entitled to receive dividends in such amounts and at such times as declared by
their respective Boards of Directors.

         The ability of the Company to pay cash dividends to shareholders is
limited by its ability to receive dividends from the Bank. As discussed in Note
K to the consolidated financial statements, the State of Ohio places certain
limitations on the payment of dividends by Ohio state-chartered banks. The
Company paid a split-adjusted cash dividend of $.064 per share during the
six-month period ended June 30, 1995. Commencing with the fourth quarter of
1995, the Company has declared the following quarterly cash dividends:

<TABLE>
<CAPTION>
Quarter            Dividend

12/31/96             0.06
3/31/97              0.06
</TABLE>

The payment of any future dividends will be at the discretion of the Company's
Board of Directors and will be based on the Company's future earnings, financial
condition, capital requirements and other relevant factors.

         Commencing with the six-month period ending June 15, 1995, Unity has
declared the following cash dividends:

<TABLE>

MEETINGS OF SHAREHOLDERS

         The Unity Constitution provides that the annual meeting of shareholders
is to be held on the third Monday of January of each year. The Unity
Constitution allows a special meeting of shareholders to be called by the
Chairman of the Board, President, Vice President, a majority of the members of
the Board, or by persons who hold 25% of the voting power of Unity. The Unity
Constitution provides that the shareholders present in person or by proxy
constitute a quorum. The Oak Hill Regulations provide that the annual meeting of
shareholders shall be held each year as the Board of Directors may decide. The
Oak Hill Regulations provide that special meetings of shareholders may be called
by the President or, in case of the President's disability, any officer who is a
member of the Board of Directors, or by the Board of Directors by action at a
meeting or by shareholders holding 50% or more of the voting power of the
Company. Except as otherwise provided by law or by the Oak Hill Articles, a
quorum for any meeting of the Company shareholders is a majority of the capital
stock issued and outstanding and entitled to vote at the meeting.

SHAREHOLDER NOMINATIONS AND PROPOSALS

         Unity's Constitution provides that candidates for directors may be
nominated by any shareholder by filing the names of such candidates in writing
with the secretary of Unity at least two weeks prior to the election.

         The Oak Hill Regulations provide that shareholders seeking to bring
business before a meeting of shareholders, or to nominate candidates for
election as directors at a meeting of shareholders, must provide timely notice
thereof in writing. To be timely, a shareholder's notice must be delivered to,
or mailed and received at, the principal executive office of the Company, not
less than 30 days nor more than 60 days prior to the scheduled meeting. The Oak
Hill


                                      -70-
<PAGE>   80
Regulations also specify certain requirements pertaining to the form and
substance of a shareholder's notice. These provisions may preclude some
stockholders from making nominations for directors at an annual or special
meeting or from bringing other matters before the stockholders at a meeting.

         Although the Company's corporate documents do not give the Company's
Board of Directors any power to approve or disapprove shareholder nominations
for the election of directors or proposals for action, the foregoing provisions
may have the effect of precluding a contest for the election of directors or the
consideration of stockholder proposals if the proper procedures are not
followed, and of discouraging or deterring a third party from conducting a
solicitation of proxies to elect its own slate of directors or to approve its
own proposal, without regard to whether consideration of such nominees or
proposals might be harmful or beneficial to the Company and its stockholders. On
the other hand, by requiring advance notice of nominations by stockholders,
these stockholder notice procedures afford the Company's Board of Directors an
opportunity to consider the qualifications of the proposed nominees and, to the
extent deemed necessary or desirable by the Company's Board of Directors, to
inform stockholders about such qualifications. By requiring advance notice of
other proposed business, the stockholder notice procedures provide a more
orderly procedure for conducting annual meetings of stockholders and, to the
extent deemed necessary or desirable by the Company's Board of Directors,
provide the Board with an opportunity to inform stockholders, prior to such
meeting, of any business proposed to be conducted at the meeting, together with
any recommendations by the Company's Board of Directors or statements as to the
Company's Board of Director's position regarding action to be taken with respect
to such business, so that stockholders can better decide whether to attend the
meeting or to grant a proxy regarding the disposition of any such business.

AMENDMENT OF ARTICLES OF INCORPORATION AND CODE OF REGULATIONS

         Unity's Articles provide that its articles may be amended by the
affirmative vote of the holders of at least three-fifths of the voting power of
Unity. The Oak Hill Articles and Oak Hill Regulations are silent as to
amendments to the Articles of Incorporation. Section 1701.70 of the OGCL
provides that directors of a corporation may amend articles in limited
circumstances. Section 1701.71 of the OGCL provides that shareholders may adopt
amendments to the articles by the affirmative vote of two-thirds of the voting
power of the corporation.

         The Unity Constitution may be amended at any annual or special meeting
of the shareholders by at least three-fifths of the voting power of Unity.

         The Oak Hill Regulations provide that certain provisions in the Oak
Hill Regulations may not be altered, amended or repealed in any respect, and new
provisions inconsistent therewith may not be adopted unless such action is
approved by the affirmative vote of the holders of at least 66 2/3% of all of
the outstanding shares of capital stock of the Company entitled to vote on such
matter at a meeting of shareholders called for that purpose. All of the
amendments may be approved by an affirmative vote of a majority of the voting
power of the Company.

DISSENTERS' RIGHTS

         Section 1701.85 of the OGCL provides for dissenters' rights in certain
circumstances to the shareholders of a corporation that is a party to a merger.
In order to exercise such rights, shareholders must comply with the procedural
requirements of Section 1701.85, attached hereto as Appendix D. See "THE MERGER-
Dissenters' Rights."

ACTION BY WRITTEN CONSENT

         The OGCL provides that, unless otherwise provided in the articles of
incorporation, any action that is required to be taken at any annual or special
meeting of shareholders, or any action which may be taken at any annual or
special meeting of shareholders, may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by all shareholders who would be entitled to notice of a
meeting held for such purpose. The Unity Constitution and the Oak Hill
Regulations allow for actions by unanimous written consent without a meeting.


                                      -71-
<PAGE>   81
SIZE AND CLASSIFICATION OF BOARD OF DIRECTORS; REMOVAL OF DIRECTORS; FILLING
VACANCIES

         Pursuant to the Unity Constitution, the Unity Board of Directors shall
be elected at the annual meeting of shareholders. The directors shall be elected
by the shareholders in such numbers and to serve for such terms that the terms
of an equal number of directors, as nearly as possible, will expire each year. A
term may not exceed three years. The number of authorized Unity directors is not
less than five and no more than seven. The Unity Constitution provides that a
director may be removed from office, with or without assigning cause, only by
the vote of the holders of not less than 75% of the Unity Common Shares.

         The Oak Hill Articles provide for the Oak Hill Board of Directors to be
divided into two classes of directors, serving staggered two-year terms. As a
result, approximately one-half of the Company's Board of Directors will be
elected each year. Classification of the Company's Board of Directors expands
the time required to change the composition of a majority of directors and may
tend to discourage a proxy contest or other takeover bid for the Company. The
Oak Hill Regulations provide that a director may be removed for cause only.

         With respect to both Oak Hill and Unity, holders of a majority of the
shares of common stock entitled to vote in any election of directors of such
corporation may elect all of the directors standing for election. Classification
of the Company's directors has the effect of making it more difficult for
shareholders to change the composition of the Company's Board of Directors. Such
a delay may help ensure that incumbent directors, if confronted by a holder
attempting to force a proxy contest, a tender or exchange offer, or any other
extraordinary corporate transaction, would have sufficient time to review the
proposal as well as any available alternatives to the proposal and to act in
what they believe to be the best interests of the stockholders. See "RISK
FACTORS - Control by Management; Anti-Takeover Provisions."

LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS.

         Section 1701.59 of the OGCL provides that a director shall not be found
to have violated his duties under the OGCL unless it is proved by clear and
convincing evidence that the director has not acted in good faith, in a manner
he reasonably believes to be in or not opposed to the best interests of the
corporation, or with the care that an ordinary prudent person in a like position
would use under similar circumstances.

         Section 1701.13 of the OGCL allows for corporations to indemnify
officers and directors from actions, suits or proceedings arising out of their
service to the corporation. The Unity Articles require that Unity indemnify any
director, officer, employee, or agent or any former director, officer, employee
or agent of the Company against expenses, reasonably incurred in any threatened,
pending or completed action to which such persons are parties by reason of their
performance of their duties for Unity.

         The Company's Regulations provide that the Company shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Company) by reason of the fact that he is or was a director of the
Company, or while a director of the Company is or was serving at the request of
the Company as a director, trustee, fiduciary, officer, employee, partner, joint
venturer or agent of another corporation, domestic or foreign, nonprofit or for
profit, partnership, joint venture, trust, employee benefit plan or other
enterprise, and the Company may indemnify or agree to indemnify any person who
is or was a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Company) by
reason of the fact that he is or was an officer, employee or agent of the
Company or while an officer, employee or agent of the Company is or was serving
at the request of the Company as a director, trustee, fiduciary, officer,
employee, partner, joint venturer or agent of another corporation, domestic or
foreign, nonprofit or for profit, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company, and with respect to any criminal action or proceeding,
had no reasonable cause to believe his conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement or conviction, or
upon a plea of nolo contendere or its equivalent, shall not,


                                      -72-
<PAGE>   82
of itself, create a presumption that the person did not act in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Company, and with respect to any criminal action or proceeding, he had
reasonable cause to believe that his conduct was unlawful.


INTERESTED SHAREHOLDER TRANSACTIONS.

         Chapter 1704 of the OGCL prohibits certain transactions between an Ohio
corporation and an "interested shareholder." Chapter 1704 allows for a
corporation to exclude itself from Chapter 1704 by exempting itself in its
Articles of Incorporation. Unity has not excluded itself from Section 1704 and
the Company's Articles expressly provide that Chapter 1704, now or hereafter in
effect, shall be applicable to the Company.

PREEMPTIVE RIGHTS

         Neither the Company's nor Unity's shareholders have preemptive rights
to purchase or subscribe for additional securities of the Company upon any
future issuance by such corporation of such securities.

REPURCHASE AND REDEMPTION OF STOCK

         Ohio corporations may generally purchase or redeem their own shares of
capital stock. The Unity Articles provide that the Board of Directors has the
right to purchase shares of its own stock. The Oak Hill Articles are silent as
to the repurchase of capital stock.


                                     EXPERTS

         The consolidated financial statements of the Company as of December 31,

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


Board of Directors
Oak Hill Financial, Inc.

We have audited the accompanying consolidated financial statements of Oak Hill
Financial, Inc. as of December 31, 1996 and 1995, and the related consolidated
statements of earnings, stockholders' equity, and cash flows for each of the
three years ended December 31, 1996, 1995 and 1994. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Oak Hill
Financial, Inc. as of December 31, 1996 and 1995, and the consolidated results
of its operations and its cash flows for each of the three years ended December
31, 1996, 1995 and 1994, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

             Three months ended March 31, 1997 and 1996 (unaudited)
                and years ended December 31, 1996, 1995 and 1994


NOTE A - SUMMARY OF ACCOUNTING POLICIES

    The business activities of Oak Hill Financial, Inc. (the "Company") have
    been limited primarily to holding the common shares of Oak Hill Banks (the
    "Bank"). Accordingly, the Company's results of operations are dependent upon
    the results of the Bank's operations. The Bank conducts a general commercial
    banking business in southeastern and south central Ohio which consists of
    attracting deposits from the general public and applying those funds to the
    origination of loans for commercial, consumer and residential purposes. The
    Bank's profitability is significantly dependent on net interest income,
    which is the difference between interest income generated from
    interest-earning assets (i.e. loans and investments) and the interest
    expense paid on interest-bearing liabilities (i.e. customer deposits and
    borrowed funds). Net interest income is affected by the relative amount of
    interest-earning assets and interest-bearing liabilities and the interest
    received or paid on these balances. The level of interest rates paid or
    received by the Bank can be significantly influenced by a number of
    competitive factors, such as governmental monetary policy, that are outside
    of management's control.

    The consolidated financial information presented herein has been prepared in
    accordance with generally accepted accounting principles ("GAAP") and
    general accounting practices within the financial services industry. In
    preparing financial statements in accordance with GAAP, management is
    required to make estimates and assumptions that affect the reported amounts
    of assets and liabilities and the disclosure of contingent assets and
    liabilities at the date of the financial statements and revenues and
    expenses during the reporting period. Actual results could differ from such
    estimates.

    The following is a summary of the Company's significant accounting policies
    which, with the exception of the policy described in Note A-3, have been
    consistently applied in the preparation of the accompanying consolidated
    financial statements.

    1.  Principles of Consolidation

    The consolidated financial statements include the accounts of the Company
    and its wholly-owned subsidiary, the Bank. All significant intercompany
    balances and transactions have been eliminated.

    2.  Investment Securities

    The Company accounts for investment securities in accordance with Statement
    of Financial Accounting Standards ("SFAS") No. 115 "Accounting for Certain
    Investments in Debt and Equity Securities." SFAS No. 115 requires that
    investments be categorized as held to maturity, trading, or available for
    sale. Securities classified as held to maturity are carried at cost only if
    the Company has the positive intent and ability to hold these securities to
    maturity. Trading securities and securities available for sale are carried
    at fair value with resulting unrealized

                            OAK HILL FINANCIAL, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

             Three months ended March 31, 1997 and 1996 (unaudited)
                and years ended December 31, 1996, 1995 and 1994


NOTE A - SUMMARY OF ACCOUNTING POLICIES (continued)

    2.  Investment Securities (continued)

    gains or losses charged to operations or stockholders' equity, respectively.
    In December 1995, pursuant to the FASB's Implementation Guide on SFAS No.
    115, the Company elected to transfer all investment securities previously
    identified as held to maturity, to an available for sale classification.
    Accordingly, the Company transferred securities totaling approximately $12.5
    million to an available for sale classification, and recorded an increase of
    $23,000 to stockholders' equity, which represented the unrealized gain on
    such securities, net of applicable tax effects. At March 31, 1997 and
    December 31, 1996 and 1995, the Company's stockholders' equity reflected
    unrealized gains on securities designated as available for sale, net of
    applicable tax effects, totaling $(95,000), $32,000 and $110,000,
    respectively.

    Realized gains and losses on securities are recognized using the specific
    identification method.

    3.  Loans Receivable

    Loans held in portfolio are stated at the principal amount outstanding,
    adjusted for premiums and discounts on loans purchased and sold and the
    allowance for loan losses. Premiums and discounts on loans purchased and
    sold are amortized and accreted to operations using the interest method over
    the average life of the underlying loans.

    Interest is accrued as earned unless the collectibility of the loan is in
    doubt. Uncollectible interest on loans that are contractually past due is
    charged off, or an allowance is established based on management's periodic
    evaluation. The allowance is established by a charge to interest income
    equal to all interest previously accrued, and income is subsequently
    recognized only to the extent that cash payments are received until, in
    management's judgment, the borrower's ability to make periodic interest and
    principal payments has returned to normal, in which case the loan is
    returned to accrual status.

    Loans held for sale are carried at the lower of cost or market, determined
    in the aggregate. Loans held for sale are identified at the point of
    origination. In computing lower of cost or market, deferred loan origination
    fees are deducted from the principal balance of the related loan. All loan
    sales are made without further recourse to the Company. At March 31, 1997
    and December 31, 1996 and 1995, loans held for sale were carried at cost.

                            OAK HILL FINANCIAL, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

             Three months ended March 31, 1997 and 1996 (unaudited)
                and years ended December 31, 1996, 1995 and 1994


NOTE A - SUMMARY OF ACCOUNTING POLICIES (continued)

    3.  Loans Receivable (continued)

    The Company generally retains the servicing on loans sold and agrees to
    remit to the investor loan principal and interest at agreed-upon rates. In
    May 1995, Financial Accounting Standards Board (the "FASB") issued SFAS No.
    122 "Accounting for Mortgage Servicing Rights," which requires that the
    Company recognize as separate assets, rights to service mortgage loans for
    others, regardless of how those servicing rights are acquired. An
    institution that acquires mortgage servicing rights through either the
    purchase or origination of mortgage loans and sells those loans with
    servicing rights retained would allocate some of the cost of the loans to
    the mortgage servicing rights.

    SFAS No. 122 requires that securitization of mortgage loans be accounted for
    as sales of mortgage loans and acquisitions of mortgage-backed securities.
    Additionally, SFAS No. 122 requires that capitalized mortgage servicing
    rights and capitalized excess servicing receivables be assessed for
    impairment. Impairment is measured based on fair value.

    SFAS No. 122 is applicable to fiscal years beginning after December 15,
    1995, (January 1, 1996, as to the Company) to transactions in which an
    entity acquires mortgage servicing rights and to impairment evaluations of
    all capitalized mortgage servicing rights and capitalized excess servicing
    receivables whenever acquired. Retroactive application was prohibited, and
    earlier adoption was encouraged. Management adopted SFAS No. 122 as of
    January 1, 1996, as required, without material effect on the Company's
    consolidated financial condition and results of operations.

    4.  Loan Origination and Commitment Fees

    The Company accounts for loan origination fees and costs in accordance with
    SFAS No. 91, "Accounting for Nonrefundable Fees and Costs Associated with
    Originating or Acquiring Loans and Initial Direct Costs of Leases". Pursuant
    to the provisions of SFAS No. 91, all loan origination fees received, net of
    certain direct origination costs, are deferred on a loan-by-loan basis and
    amortized to interest income using the interest method, giving effect to
    actual loan prepayments. Additionally, SFAS No. 91 generally limits the
    definition of loan origination costs to the direct costs attributable to
    originating a loan, i.e., principally actual personnel costs.

    Fees received for loan commitments are deferred and amortized over the life
    of the related loan using the interest method.

NOTE A - SUMMARY OF ACCOUNTING POLICIES (continued)

    5.  Allowance for Loan Losses

    It is the Company's policy to provide valuation allowances for estimated
    losses on loans based upon past loss experience, trends in the level of
    delinquent and specific problem loans, adverse situations that may affect
    the borrower's ability to repay, the estimated value of any underlying
    collateral and current and anticipated economic conditions in the primary
    market area. When the collection of a loan becomes doubtful, or otherwise
    troubled, the Company records a loan loss provision equal to the difference
    between the fair value of the property securing the loan and the loan's
    carrying value. Major loans and major lending areas are reviewed
    periodically to determine potential problems at an early date. The allowance
    for loan losses is increased by charges to earnings and decreased by
    charge-offs (net of recoveries).

    In May 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
    Impairment of a Loan". This Statement, which was amended by SFAS No. 118 as
    to certain income recognition and financial statement disclosure provisions,
    requires that impaired loans be measured based upon the present value of
    expected future cash flows discounted at the loan's effective interest rate
    or, as an alternative, at the loans observable market price or fair value of
    the collateral. The Company adopted SFAS No. 114 effective January 1, 1995,
    without material effect on consolidated financial condition or results of
    operations.

    A loan is defined under SFAS No. 114 as impaired when, based on current
    information and events, it is probable that a creditor will be unable to
    collect all amounts due according to the contractual terms of the loan
    agreement. In applying the provisions of SFAS No. 114, the Company considers
    its investment in one-to-four family residential loans, consumer installment
    loans and credit card loans to be homogeneous and therefore excluded from
    separate identification for evaluation of impairment. With respect to the
    Company's investment in impaired commercial loans, such loans are collateral
    dependent and as a result are carried as a practical expedient at the lower
    of cost or fair value.

    It is the Company's policy to charge off unsecured credits that are more
    than ninety days delinquent. Similarly, collateral dependent loans which are
    more than ninety days delinquent are considered to constitute more than a
    minimum delay in repayment and are evaluated for impairment under SFAS No.
    114 at that time.

    At March 31, 1997 and December 31, 1996 and 1995, the Company had no loans
    that would be defined as impaired under SFAS No. 114.

    6.  Office Premises and Equipment

    Depreciation and amortization are provided on the straight-line and
    accelerated methods over the estimated useful lives of the assets, estimated
    to be ten to fifty years for buildings and improvements and three to
    twenty-five years for furniture, fixtures and equipment.

    7.  Real Estate Acquired through Foreclosure

    Real estate acquired through foreclosure is carried at the lower of the
    loan's unpaid principal balance (cost) or fair value less estimated selling
    expenses at the date of acquisition. The loan loss allowance is charged for
    any write down in the loan's carrying value to fair value at the date of
    acquisition. Real estate loss provisions are recorded if the properties'
    fair value subsequently declines below the value determined at the recording
    date. In determining the lower of cost or fair value at acquisition, costs
    relating to development and improvement of property are considered. Costs
    relating to holding real estate acquired through foreclosure, net of rental
    income, are charged against earnings as incurred.

    8.  Federal Income Taxes

    The Company accounts for federal income taxes pursuant to SFAS No. 109,
    "Accounting for Income Taxes." SFAS No. 109 established financial accounting
    and reporting standards for the effects of income taxes that result from the
    Company's activities within the current and previous years. It requires an
    asset and liability approach for financial accounting and reporting for
    income taxes.

    Pursuant to the provisions of SFAS No. 109, a deferred tax liability or
    deferred tax asset is computed by applying the current statutory tax rates
    to net taxable or deductible temporary differences between the tax basis of
    an asset or liability and its reported amount in the consolidated financial
    statements that will result in taxable or deductible amounts in future
    periods. Deferred tax assets are recorded only to the extent that the amount
    of net deductible temporary differences or carryforward attributes may be
    utilized against current period earnings, carried back against prior years
    earnings, offset against taxable temporary differences reversing in future
    periods, or utilized to the extent of management's estimate of future
    taxable income. A valuation allowance is provided for deferred tax assets to
    the extent that the value of net deductible temporary differences and
    carryforward attributes exceeds management's estimates of taxes payable on
    future taxable income. Deferred tax liabilities are provided on the total
    amount of net temporary differences taxable in the future.

    The Company's principal temporary differences between pretax financial
    income and taxable income result primarily from the different methods of
    accounting for deferred loan origination fees and costs, Federal Home Loan
    Bank stock dividends and the allowance for loan losses. A temporary
    difference is also recognized for depreciation expense computed using
    accelerated methods for federal income tax purposes.

    9.  Fair Value of Financial Instruments

    SFAS No. 107, "Disclosures about Fair Value of Financial Instruments",
    requires disclosure of fair value of financial instruments, both assets and
    liabilities whether or not recognized in the consolidated statement of
    financial condition, for which it is practicable to estimate that value. For
    financial instruments where quoted market prices are not available, fair
    values are based on estimates using present value and other valuation
    methods.

    The methods used are greatly affected by the assumptions applied, including
    the discount rate and estimates of future cash flows. Therefore, the fair
    values presented may not represent amounts that could be realized in an
    exchange for certain financial instruments.

    The following methods and assumptions were used by the Company in estimating
    its fair value disclosures for financial instruments at December 31, 1996
    and 1995:

                  Cash and cash equivalents: The carrying amounts presented in
                  the consolidated statement of financial condition for cash and
                  cash equivalents are deemed to approximate fair value.

                  Federal funds sold: The carrying amounts presented in the
                  consolidated statement of financial condition for federal
                  funds sold are deemed to approximate fair value.

                  Investment securities: For investment securities, fair value
                  is deemed to equal the quoted market price.

                  Loans receivable: The loan portfolio has been segregated into
                  categories with similar characteristics, such as one-to-four
                  family residential real estate, multi-family residential real
                  estate, commercial and installment and other. These loan
                  categories were further delineated into fixed-rate and
                  adjustable-rate loans. The fair values for the resultant loan
                  categories were computed via discounted cash flow analysis,
                  using current interest rates offered for loans with similar
                  terms to borrowers of similar credit quality. The historical
                  carrying amount of accrued interest on loans is deemed to
                  approximate fair value.

                  Federal Home Loan Bank Stock: The carrying amount presented in
                  the consolidated statement of financial condition is deemed to
                  approximate fair value.

                  Deposits: The fair value of NOW accounts, savings accounts,
                  demand deposits, money market deposits and other transaction
                  accounts is deemed to approximate the amount payable on demand
                  at December 31, 1996 and 1995. Fair values for fixed-rate
                  certificates of deposit have been estimated using a discounted
                  cash flow calculation using the interest rates currently
                  offered for deposits of similar remaining maturities.

    9.  Fair Value of Financial Instruments (continued)

                  Advances from the Federal Home Loan Bank: The fair value of
                  advances from the Federal Home Loan Bank has been estimated
                  using discounted cash flow analysis, based on the interest
                  rates currently offered for advances of similar remaining
                  maturities.

                  Securities sold under agreement to repurchase: The fair value
                  of securities sold under agreements to repurchase is deemed to
                  approximate fair value.

                  Commitments to extend credit: For adjustable-rate loan
                  commitments, the fair value estimate considers the difference
                  between current levels of interest rates and committed rates.

    Based on the foregoing methods and assumptions, the carrying value and fair
    value of the Company's financial instruments are as follows:

</TABLE>

    The Company's lending efforts have historically focused on real estate
    mortgages and consumer installment loans which comprise approximately $146.5
    million, or 74.3% of the total loan portfolio at March 31, 1997, $137.1
    million, or 72%, of the total loan portfolio at December 31, 1996, and
    approximately $109.5 million, or 69%, of the total loan portfolio at
    December 31, 1995. Historically, such loans have been conservatively
    underwritten with sufficient collateral or cash down payments to provide the
    Company with adequate collateral coverage in the event of default.
    Nevertheless, the Company, as with any lending institution, is subject to
    the risk that real estate values or economic conditions could deteriorate in
    its primary lending areas within Ohio, thereby impairing collateral values.
    However, management is of the belief that real estate values and economic
    conditions in the Company's primary lending areas are presently stable.

    As stated previously, the Company has sold whole loans and participating
    interests in loans in the secondary market, retaining servicing on the loans
    sold. Loans sold and serviced for others totaled approximately $29.6
    million, $28.8 million and $25.3 million at March 31, 1997, December 31,
    1996 and 1995, respectively.

NOTE H - RELATED PARTY TRANSACTIONS

    In the normal course of business, the Company has made loans to its
    directors, officers and key employees, and their related business interests.
    In the opinion of management, such loans are consistent with sound banking
    practices and are within applicable regulatory lending limitations. The
    balance of such loans outstanding at March 31, 1997 and December 31, 1996,
    1995 and 1994 totaled approximately $1.5 million, $1.6 million, $2.5 million
    and $462,000, respectively.

    The Company had also received demand and time deposits of approximately $1.2
    million and $1.7 million at March 31, 1997 and 1996, respectively, and $5.4
    million, $3.7 million and $3.7 million at December 31, 1996, 1995 and 1994
    from directors, officers and their related business interests.


NOTE I - EMPLOYEE BENEFIT PLANS

    The Company has a profit-sharing and 401(k) plan covering all employees who
    have attained the age of twenty-one and completed one full year of service.

    The profit-sharing plan is non-contributory and contributions to the plan
    are at the discretion of the Board of Directors. The Company recorded
    expense totaling $31,250 and $31,250 in connection with the Plan for the
    three month periods ended March 31, 1997 and 1996, respectively. The Company
    contributed $125,000, $69,000 and $125,000 to the Plan for the years ended
    December 31, 1996, 1995 and 1994, respectively.

    The 401(k) plan allows employees to make voluntary, tax deferred
    contributions up to 15% of their base annual compensation. The Company
    provides, at its discretion, a 50% (25% for 1994) matching of funds for each
    participant's contribution, subject to a maximum of 6% of base compensation.
    If the participant elects to invest their contributions in the common stock
    of Oak Hill Financial, Inc., the Company will provide a 100% matching of
    each participants contribution. The Company's matching contributions under
    the 401(k) plan totaled $25,000 and $11,500 for the three month periods
    ended March 31, 1997 and 1996, and $100,000, $46,000 and $20,000 for the
    years ended December 31, 1996, 1995 and 1994, respectively.


NOTE J - LOAN COMMITMENTS

    The Company is a party to financial instruments with off-balance sheet risk
    in the normal course of business to meet the financing needs of its
    customers including commitments to extend credit. Such commitments involve,
    to varying degrees, elements of credit and interest-rate risk in excess of
    the amount recognized in the statement of financial condition. The contract
    or notional amounts of the commitments reflect the extent of the Company's
    involvement in such financial instruments.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

             Three months ended March 31, 1997 and 1996 (unaudited)
                and years ended December 31, 1996, 1995 and 1994


NOTE J - LOAN COMMITMENTS (continued)

    The Company's exposure to credit loss in the event of nonperformance by the
    other party to the financial instrument for commitments to extend credit is
    represented by the contractual notional amount of those instruments. The
    Company uses the same credit policies in making commitments and conditional
    obligations as those utilized for on-balance-sheet instruments.

    At March 31, 1997 and December 31, 1996, the Company had outstanding
    commitments of approximately $3.8 million and $3.9 million to originate
    variable rate residential and commercial loans. Also, the Company has unused
    lines of credit and letters of credit totaling approximately $5.2 million
    and $1.2 million at March 31, 1997, and $4.8 million and $1.1 million,
    respectively, as of March 31, 1997 and December 31, 1996. In the opinion of
    management, outstanding loan commitments equaled or exceeded prevalent
    market interest rates as of December 31, 1996, such commitments were
    underwritten in accordance with normal loan underwriting policies, and all
    disbursements will be funded via cash flow from operations and existing
    excess liquidity.


NOTE K - STOCKHOLDERS' EQUITY AND REGULATORY CAPITAL

    The Bank is required to maintain minimum amounts of risk-weighted capital
    and leverage capital, as defined by banking regulations. At December 31,
    1996, the Bank was required to have minimum leverage capital and total
    risk-weighted capital ratios of 4.0% and 8.0%, respectively. The Bank's
    actual leverage and risk-weighted capital ratios at March 31, 1997 were 9.3%
    and 12.9%, December 31, 1996 were 9.4% and 13.1%, and at December 31, 1995
    were 13.7% and 14.9%, respectively. As a result, the Bank met the definition
    of a well-capitalized financial institution under federal regulations.

    The principal source of the Company's revenues are cash dividends received
    from the Bank. The Ohio banking laws impose certain limitations on the
    payment of dividends by Ohio state chartered banks, as follows: (1) no
    dividends may be paid which would reduce the surplus to less than 20% of
    capital; (2) the Ohio Superintendent of Financial Institutions (the
    Superintendent) must approve any dividend the total of which exceeds the
    total of net profits of that fiscal year combined with net profits of the
    preceding two years less any required transfers to surplus or a fund for the
    retirement of any preferred stock or capital securities. Pursuant to the
    foregoing, at December 31, 1996, the Bank had the capability of paying $4.5
    million of dividends to the Company without the Superintendent's approval.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

             Three months ended March 31, 1997 and 1996 (unaudited)
                and years ended December 31, 1996, 1995 and 1994


NOTE L - STOCK OPTION PLAN

    The Board of Directors of the Company had approved a Stock Option Plan in
    1993 (the "1993 Plan"). Pursuant to the 1993 Plan, options to purchase
    108,500 shares of common stock were granted to officers at an exercise price
    of $2.86 per share, subject to a five year vesting period. Compensation
    expense of $211,000 and $62,000 was recognized for the years ended December
    31, 1995 and 1994. In contemplation of the Company's common stock offering
    in August 1995, the Plan's vesting period was waived. As a result, the
    Company's officers exercised all outstanding options during 1995 at a
    pre-tax cost of approximately $180,000 to the Company. The 1993 Plan was
    terminated in August 1995.

    The Company initiated a Stock Option Plan in August 1995 (the "1995 Plan")
    that provides for the issuance of 200,000 shares of authorized, but unissued
    shares of common stock. The Board of Directors granted stock options to
    purchase 22,000 shares of stock at an exercise price of $9.75 per share at
    the completion of the Company's common stock offering. During the years
    ended December 31, 1996 and 1995, respectively, an additional 65,500 and
    18,400 options were granted at exercise prices ranging from $9.25 to $12.50
    on the date of grant. During 1996, 1,000 stock options granted were
    exercised. At March 31, 1997 and December 31, 1996, unexercised shares under
    option in the 1995 Plan totaled 104,900, at exercise prices ranging from
    $9.25 to $12.50.

    The Company applies Accounting Principles Board Opinion No. 25 and related
    Interpretations in accounting for its stock option plan. Accordingly, no
    compensation cost has been recognized for the plan. Had compensation cost
    for the Company's stock option plan been determined based on the fair value
    at the grant dates for awards under the plan consistent with the accounting
    method utilized in SFAS No. 123, the Company's net earnings and earnings per
    share would have been reduced to the pro forma amounts indicated below:

    The fair value of each option grant is estimated on the date of grant using
    the modified Black- Scholes options-pricing model with the following
    weighted-average assumptions used for grants in 1996 and 1995, respectively;
    dividend yield of 7.5% and expected volatility of 30.0% for all years;
    risk-free interest rates of 6.15% and 6.05% and expected lives of eight
    years.

     savings bank, will merge with and into the Company, with the combined
     institutions continuing operations as a wholly-owned subsidiary of Oak Hill
     Financial Corporation. The merger was approved by regulatory authorities in
     fiscal 1997. The business combination will be accounted for as a pooling of
     interests and, accordingly, the assets, liabilities and capital of Unity
     and the Corporation will be added together at historic carrying value.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



Board of Directors and Shareholders
Unity Savings Bank
McArthur, Ohio


We have audited the accompanying statements of financial condition of Unity
Savings Bank as of December 31, 1996 and 1995, and the related statements of
income, shareholders' equity and cash flows for the years then ended. We have
also audited the statements of income, shareholder's equity and cash flows for
the year ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Unity Savings Bank as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for the years ended December 31, 1996, 1995 and 1994, in conformity with
generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS



1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Method of Accounting

     The accrual method of accounting is used and applied consistently for
     financial statement and federal income tax reporting purposes.

     Business Activity

     The Company's activities consist principally of acquiring the savings of
     the public and investing in mortgage loans on real estate. Savings are also
     invested in marketable securities and other types of loans.
     The Company provides these services in Southeastern Ohio.

     Cash and Cash Equivalents

     For the purpose of the Statement of Cash Flows, cash and cash equivalents
     include all debt instruments with original maturities of three months or
     less.

     Office Property and Equipment

     These assets are recorded at cost and depreciated over 5 to 33 1/3 years by
     the straight line method for financial statement purposes. Repairs and
     maintenance are charged to expense when paid. Gains and losses from the
     sale of these assets are included in income.

     The estimated useful lives of the respective assets for financial statement
     purposes are as follows:

     Buildings and Improvements                       6 to 33 1/3 Years
     Furniture, and Equipment                         5 to 12 Years

     Discounts and Premiums on Purchased Mortgage Loan

     Discounts and premiums on purchased mortgage loans are amortized over the
     life of the securities on the interest method basis.

     Earnings Per Share

     Earnings per share are based upon 93,250 weighted average shares
     outstanding during the three months ended March 31, 1997 and each of the
     years ended December 31, 1996, 1995, and 1994.

     Provision for Losses

     Provisions for losses on loans, accrued interest and real estate owned are
     charged to earnings when it is determined that the investment in such
     assets is greater than estimated net realizable value.

     The allowance for loan losses is increased by charges to income and
     decreased by charge-offs (net of recoveries). Management's periodic
     evaluation of the adequacy of the allowance is based on the Company's past
     loan loss experience, known and inherent risks in the portfolio, adverse
     situations that may affect the borrower's ability to repay the estimated
     value of any underlying collateral, current economic conditions, and
     recommendations made by Federal regulatory agencies.

     An allowance is established for uncollectible interest on loans that are
     contractually past due, based on management's periodic evaluation. The
     allowance is established by a charge to interest income equal to all
     interest previously accrued, and income is subsequently recognized only to
     the extent that cash payments are received until, in management's judgment,
     the borrower's ability to make periodic interest and principal payments is
     back to normal, in which case the loan is returned to accrual status.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Provision for Losses (continued)

     On January 1, 1996 Unity Savings Bank adopted SFAS No. 114, Accounting by
     Creditors for Impairment of a Loan, and SFAS No. 118, Accounting by
     Creditors for Impairment of a Loan - Income Recognition and Disclosures (an
     amendment of SFAS No. 114). These pronouncements require that impaired
     loans be measured based on the present value of expected future cash flows
     or at the loan's observable market price or the fair value of the
     collateral if the loan is collateral dependent. If the value computed is
     less than the recorded value of the loan, a valuation allowance is recorded
     for the difference. The entire change in valuation allowance is reported as
     a component of the provision for bad debt expense.

     Cash, Federal Funds and Other Investments

     In accordance with regulations, the Company must maintain an amount of
     cash, U.S. Government securities and other approved debt securities that
     are readily convertible to cash, equal to or exceeding a prescribed
     percentage of total savings and short-term borrowings. The Company has
     satisfied such requirements through December 31, 1996.

     Investments

     Management has elected to classify investments in debt, equity and mortgage
     backed securities as available-for-sale and carry them at fair value.
     Unrealized gains and losses on securities, net of deferred income taxes, in
     this classification are recognized as direct increases or decreases to
     stockholders' equity.

     Loans Receivable

     Loans receivable are stated at unpaid principal balances, less an allowance
     for loan losses and net of deferred loan-origination fees and discounts.

     Discounts on mobile home and consumer loans are amortized to income using
     the effective interest method over the remaining period to contractual
     maturity, adjusted for anticipated prepayments.

     Loan Origination Fees and Discounts on Mortgage Loans

     Loan fees received are accounted for in accordance with SFAS Statement No.
     91, Accounting for Non-refundable Loan Fees and Costs Associated with
     Originating or Acquiring Loans and Initial Direct Costs of Leases. Net loan
     fees for originating loans are deferred and are amortized by the interest
     method over the life of the loan.

     Income Taxes

     Provisions for income taxes are based on amounts reported in the statements
     of income (after exclusion of non-taxable income such as interest on state
     and municipal securities) and include deferred taxes on temporary
     differences in the recognition of income and expense for tax and financial
     statement purposes. Deferred taxes are computed using the asset and
     liability approach as prescribed in SFAS Statement No.
     109, Accounting for Income Taxes.

     For federal income tax reporting purposes, property and equipment are
     depreciated over their estimated useful lives ranging from 5 to 33 1/3
     years by the straight line and accelerated methods.

     Use of Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Use of Estimates (continued)

     Material estimates that are particularly susceptible to significant change
     relate to the determination of the allowance for losses on loans and the
     valuation of real estate owned held-for-sale. In connection with the
     determination of the allowances for losses on loans and real estate owned
     held-for-sale, management obtains independent appraisals for significant
     properties.

     A majority of the Company's loan portfolio consists of one-to-four family
     residential loans in the Southeastern Ohio area. The economy is primarily
     dependent upon the timber industry, light manufacturing and agriculture.
     Accordingly, the ultimate collectibility of a substantial portion of the
     Company's portfolio is susceptible to changes in local market conditions.

     While management uses available information to recognize losses on loans,
     future changes to the allowance may be necessary based on changes in local
     economic conditions. In addition, regulatory agencies, as an integral part
     of their examination process, periodically review the Company's allowances
     for losses on loans and foreclosed real estate. Such agencies may require
     the Company to make changes to the allowances based on their judgments
     about information available to them at the time of their examination.
     Because of these factors, the likelihood of a material change in the
     allowances for losses on loans and real estate owned held-for-sale is more
     than remote.

     Real Estate Owned

     Real estate properties acquired through, or in lieu of, loan foreclosures
     are initially recorded at the lower of cost or fair value at the date of
     foreclosure.

     Federal Home Loan Bank Stock

     Federal Home Loan Bank stock is stated at cost due to limited
     marketability. The Company has recorded its minority investment in the
     common stock of Intrieve, Incorporated, at cost which at March 31, 1997,
     December 31, 1996 and 1995, closely approximates market.

     Basis of Presentation

     The financial statements as of March 31, 1997, and for the three months
     ended March 31, 1997 and 1996, including the footnote data related thereto,
     are unaudited. However, in the opinion of management, all adjustments
     (consisting only of normal recurring accruals) which are necessary for a
     fair presentation of financial position, results of operations and cash
     flows have been made.

2.   INTEREST RECEIVABLE

     Interest receivable consists of the following:

</TABLE>

     The Company has qualified under provisions of the Internal Revenue Code to
     deduct from taxable income an allowance for bad debts based on the
     experience method.

     Appropriated and unappropriated retained earnings as of December 31, 1996,
     include $1,756,744 of bad debt deductions. A deferred tax liability of
     $133,713, was established relating to the increase in the bad debt
     deduction of $385,427 from 1987 through 1996. If, in the future, the
     Company fails to meet the federal income tax requirements permitting it to
     deduct such losses, the effective tax rate would increase to a maximum of
     34% under present law. If the amounts that qualify as deductions for
     federal income tax purposes are later used for purposes other than for bad
     debt losses, including distributions in liquidations, they will be subject
     to federal income tax at the corporate rate then in effect. The tax effect
     of the loss of the reserve would be $594,625 at rates in effect at December
     31, 1996. For effects of Small Business Act of 1996 see Note 10.

     Included in retained earnings at both December 31, 1996 and 1995, is
     approximately $1,363,000 in bad debt reserves for which no deferred federal
     income tax liability has been recorded. These amounts represent allocations
     of income to bad debt deductions for tax purposes only. Reduction of these
     reserves for purposes other than tax bad-debt losses or adjustments arising
     from carryback of net operating losses would create income for tax
     purposes, which would be subject to the then-current corporate income tax
     rate. The unrecorded deferred liability on these amounts was approximately
     $463,000 at both December 31, 1996 and 1995.

     Prior to 1996, the Company qualified under provisions of the Internal
     Revenue Code to deduct from taxable income any allowance for bad debts on
     either the percentage of income or the experience method. The Small
     Business Act of 1996 eliminated the percentage of income method of
     computing bad debts for thrift institutions for years beginning after
     December 31, 1995. It further requires recapture of excess bad debt
     reserves over a six to eight year period starting with the first tax year
     following December 31, 1995. The Company's excess reserve at December 31,
     1995 was $385,000. The excess reserve will cause a six year $64,238 annual
     recapture into income. This recapture was suspended for one year due to the
     Company meeting the "residential loan requirement" of the Act for December
     31, 1996. If the Company meets the same provision in 1997, the recapture
     can be suspended for an additional year.

11.  RELATED PARTY TRANSACTIONS

     At March 31, 1997, December 31, 1996 and 1995, the Company had loans
     outstanding to officers and directors of approximately $146,000, $151,000
     and $149,000, respectively.

     All of the stock of Knox Insurance Agency, Inc. (Knox) is owned by the
     Chariman of the Board and Director of Unity Savings Bank. The Company
     purchases fire and casualty insurance and a savings and loan blanket bond
     from Knox. Total premiums paid from the Company to Knox for the three
     months ended March 31, 1997 and 1996, and for the years ended December 31,
     1996, 1995 and 1994 were approximately $17,000, $15,000, $15,000, $15,000
     and $14,000, respectively. Knox leases office space from the Company for
     $2,100 per annum.

12.  GOODWILL

     Goodwill resulting from the excess of liabilities assumed over the fair
     market value of assets acquired from the Citizens Building and Loan
     Company, amounted to $48,181. This balance is being amortized on the
     straight line method over a ten year period. Accumulated amortization
     amounted to approximately $40,000, $39,000 and $34,000, at March 3, 1997,
     December 31, 1996 and 1995, respectively.

13.  LEASE CONTRACT

     The Company entered into an agreement to lease its former office in
     McArthur, Ohio on December 1, 1992. The lease was renewed on November 16,
     1993 for the term December 1, 1993 to November 30, 1995. The lease was
     extended for an additional term from December 1, 1996 to December 15, 1998.
     Lease payments amount to $925 per month.

14.  REGULATORY CAPITAL

     The Bank is subject to various regulatory capital requirements administered
     by the federal banking agencies. Failure to meet minimum capital
     requirements can initiate certain mandatory--and possibly additional
     discretionary--actions by regulators that, if undertaken, could have a
     direct material effect on the Bank's financial statements. Under capital
     adequacy guidelines and the regulatory framework for corrective action, the
     Bank must meet specific capital guidelines that involve quantitative
     measures of the Bank's assets, liabilities, and certain off-balance-sheet
     items as calculated under regulatory accounting practices. The Bank's
     capital amounts and classification are also subject to qualitative
     judgments by the regulators about components, risk weightings, and other
     factors.

     Quantitative measures established by regulation to ensure capital adequacy
     require the Bank to maintain amounts and ratios (set forth in the table
     below) of total and Tier I capital (as defined in the regulations) to
     risk-weighted assets (as defined), and of Tier I capital (as defined) to
     average assets (as defined). Management believes, as of March 31, 1997 that
     the Bank meets all capital adequacy requirements to which it is subject.

     As of March 31, 1997 the most recent notification from the Federal Deposit
     Insurance Corporation categorized the Bank as well capitalized under the
     regulatory framework for prompt corrective action. To be categorized as
     well capitalized the Bank must maintain minimum total risk-based, Tier I
     risk-based, and Tier I leverage ratios as set forth in the table. There are
     no conditions or events since that notification that management believes
     have changed the institution's category.

15.  SIGNIFICANT CONCENTRATIONS OF CREDIT RISK

     Most of the Company's business activity is with customers located within
     the southeastern part of Ohio and, therefore, subject to the risks involved
     in economic variances within the area.

16.  DEFERRED COMPENSATION PLAN

     During 1995, the Company entered into a deferred compensation arrangement
     which provides for cash payments to be made after retirement. The
     liabilities under these arrangements have been recorded at their present
     values using an eight percent interest rate. In connection with the
     arrangements the Company has purchased life insurance policies. The Company
     is the owner and beneficiary of the policies.

18.  INSURANCE ASSESSMENT RELATING TO THE RECAPITALIZATION OF THE SAVINGS
     ASSOCIATION INSURANCE FUND (SAIF)

     In September of 1996, legislation was enacted which required certain
     financial institutions to pay a one time special assessment to recapitalize
     the SAIF. The Company's share was approximately $309,000 and was paid
     during the last half of 1996.

19.  REMOVAL OF FAIR VALUE DISCLOSURES FOR FINANCIAL INSTRUMENTS FASB 126

     During 1995 the Company adopted FASB 107 which required disclosure of the
     fair value of financial instruments in the notes of the financial
     statements. The Company adopted FASB 126 immediately upon issuance in
     December of 1996. FASB 126 suspends the requirement of disclosing the fair
     value of financial instruments for an indefinite period of time.

20.  BUSINESS COMBINATION

     During fiscal 1997, the company's Board of Directors approved a business
     combination whereby the Company will merge with and into Oak Hill Banks,
     with the combined institutions continuing operations as a wholly owned
     subsidiary of Oak Hill Financial Corporation. Approval for the merger has
     been applied for with the regulatory authorities. The business combination
     will be accounted for as a pooling of interests and, accordingly, the
     assets, liabilities and capital of the Company and Oak Hill Financial, Inc.
     will be added together at historic carrying value. Unaudited pro-forma
     condensed, combined financial information of the Company and Oak Hill
     Financial, Inc. as of and for the year ended December 31, 1996 is as
     follows:

         8. CONVERSION OF SHARES.

                  (a) All shares of Oak Hill Banks Common that are issued and
outstanding immediately prior to the Effective Time shall continue to be issued
and outstanding shares of Oak Hill Banks Common at and after the Effective Time.

                  (b) At the Effective Time, the shares of Unity Savings Common
issued and outstanding immediately prior to the Effective Time (exclusive of
treasury shares, if any, which shall be cancelled, and any shares as to which
statutory dissenters' rights are properly sought) shall be converted, by virtue
of the Merger and without further action on the part of the holders thereof,
into the right to receive shares of the common stock, without par value, of Oak
Hill Financial ("Oak Hill Financial Common"), as follows:

                  (i) Each outstanding share of Unity Savings Common shall be
         converted into the right to receive 8.5 shares of Oak Hill Financial
         Common (the "Exchange Ratio"), provided, that if the Average Closing
         Price is greater than 115% of the Starting Price, then each outstanding
         share shall be converted into the right to receive such number of
         shares as is equal to the product of multiplying 8.5 by a fraction, the
         numerator of which is 115% of the Starting Price and the denominator of
         which is the Average Closing Price. The Exchange Ratio set forth in the
         preceding sentence shall be adjusted to reflect any non-cash
         distribution, stock splits or stock dividends on Oak Hill Financial
         Common occurring or having a record date after the date hereof and
         prior to the Effective Time.

                  (ii) No fractional shares of Oak Hill Financial Common shall
         be issued. Each holder of Unity Savings Common who would otherwise be
         entitled to receive a fractional part of a share of Oak Hill Financial
         Common shall instead be entitled to receive cash in an amount equal to
         the product resulting from multiplying such fraction by the Average
         Closing Price Per Share of Oak Hill Financial Common. No interest shall
         be payable with respect to such cash payment.

                (c) Each outstanding share of Unity Savings Common held by a
person who has demanded and perfected a right to relief as a dissenting
shareholder under Section 1701.85 of the Ohio Revised Code (the "Dissenters'
Rights Law") and who has not effectively withdrawn or lost such right
("Dissenting Shares") shall not be converted into or represent a right to
receive shares of Oak Hill Financial Common pursuant to subsection 8(b) hereof,
but the holder thereof shall be entitled only to such rights as are granted by
the Dissenters' Rights Law. Each holder of Dissenting Shares who becomes
entitled to relief as a dissenting shareholder under the Dissenters' Rights Law
with respect to such holder's shares of Unity Savings Common shall receive
payment therefor from Oak Hill Financial in

                                       A-2

<PAGE>   136



accordance with the provisions of the Dissenters' Rights Law. If any holder of
Unity Savings Common who demands relief as a dissenting shareholder under the
Dissenters' Rights Law with respect to such holder's shares of Unity Savings
Common shall effectively withdraw or lose (through failure to perfect or
otherwise), the right to such relief, each share of Unity Savings Common held by
such holder shall automatically be converted into the right to receive shares of
Oak Hill Financial Common pursuant to subsection 8(b) hereof.

         9. EXCHANGE OF CERTIFICATES; PAYMENT FOR FRACTIONAL SHARES.

                (a) On the Effective Date, Oak Hill Financial shall deliver to
The Fifth Third Bank (the "Exchange Agent") the amount of cash necessary to pay
for all fractional shares of Oak Hill Financial Common in accordance with
subsection 8(b)(ii) hereof.

                (b) As promptly as practicable after the Effective Date, Oak
Hill Financial shall cause the Exchange Agent to prepare and mail to each holder
of record on the Effective Date of any shares of Unity Savings Common a letter
of transmittal containing instructions for the surrender of all certificates for
shares of Unity Savings Common. Upon the surrender by such holder of a
certificate or certificates for shares of Unity Savings Common standing in such
holder's name to the Exchange Agent in accordance with the instructions set
forth in the letter of transmittal, such holder shall be entitled to receive in
exchange therefor a certificate representing the number of whole shares of Oak
Hill Financial Common into which the shares represented by the certificate or
certificates so surrendered shall have been converted and, if applicable, a
check payable to such holder in the amount necessary to pay for any fractional
shares of Oak Hill Financial Common which such holder would otherwise have been
entitled to receive, in accordance with subsection 8(b)(ii) hereof. No interest
shall be payable with respect to either the whole shares of Oak Hill Financial
Common or the cash payable in lieu of fractional shares. Immediately after the
third anniversary of the Effective Date, the Exchange Agent shall deliver to the
Surviving Corporation any unclaimed balance of cash owing with respect to
fractional shares and such cash shall be retained by, and become the property of
the Surviving Corporation, free and clear of any claims whatsoever.

                (c) Neither Oak Hill Financial, the Surviving Corporation, nor
the Exchange Agent, shall be obligated to deliver a certificate for Oak Hill
Financial Common or a check for cash in lieu of fractional shares to a former
shareholder of Unity Savings until such former shareholder surrenders the
certificate or certificates representing shares of Unity Savings Common standing
in such former shareholder's name or, if such former shareholder is unable to
locate such certificate or certificates, an appropriate affidavit of loss and
indemnity agreement and bond as may be required by Oak Hill Financial. Until so
surrendered, each outstanding certificate for shares of Unity Savings Common
shall be deemed for all corporate purposes (except the payment of dividends) to
evidence ownership of the number of whole shares of Oak Hill Financial Common
into which the shares of Unity Savings Common represented thereby shall have
been converted.

                (d) After the Effective Date and until the outstanding
certificates formerly representing shares of Unity Savings Common are so
surrendered, no dividends or distributions payable to holders of record of Oak
Hill Financial Common shall be paid to the holders of such outstanding Unity
Savings certificates in respect thereof. Promptly upon surrender of such
outstanding certificates there shall be paid to the holders of the certificates
for Oak Hill Financial Common issued in exchange therefor the amount of
dividends and other distributions, if any, which theretofore became payable with
respect to such full shares of Oak Hill Financial Common, but which have not
theretofore been paid on such stock. No interest shall be payable with respect
to the payment of any dividends or other distributions. All such dividends or
other distributions unclaimed at the end of one year from the Effective Date
shall, to the extent such dividends have been previously paid to the Exchange
Agent, be repaid by the Exchange Agent to Oak Hill Financial, and thereafter the
holders of such outstanding certificates for Unity Savings Common shall look,
subject to applicable escheat, unclaimed funds, and other laws, only to Oak Hill
Financial as general creditors for payment thereof.

of the close of business on the day that is two business days prior to the
Effective Date.

                (f) Oak Hill Financial is empowered to adopt additional
reasonable rules and regulations with respect to the matters referred to in this
Section 9 not inconsistent with the provisions of this Agreement.

generality of the foregoing, and subject thereto, at the Effective Time, the
separate existence of Unity Savings shall cease; all assets and property (real,
personal, and mixed, tangible and intangible, choses in action, rights, and
credits) then owned by each Constituent Corporation, or which would inure to
either of them, shall immediately, by operation of law and without any
conveyance, transfer, or further action, become the assets and property of the

Corporations shall remain unimpaired and the Surviving Corporation shall succeed

Corporation or by its successors, the officers and directors of Unity Savings in
office at the Effective Time shall execute and deliver such instruments and
shall take or cause to be taken such further or other action as shall be
necessary in order to vest or perfect in the Surviving Corporation, or to

property, interests, rights, privileges, immunities, powers, franchises, and
authority of Unity Savings and otherwise to carry out the purposes of this
Agreement.

changed after the shareholders of Unity Savings have adopted this Agreement
without the approval of such shareholders in the same manner as required for the

faith, after consultation with McDonald & Company Securities, Inc., as financial
advisor to Unity Savings, with respect to the financial aspects of the
Unsolicited Acquisition Proposal and the Merger, and with legal counsel to Unity
Savings, that failure to so consider or participate in such negotiations or
discussions would be inconsistent with the fiduciary obligations of the
directors of Unity Savings to the shareholders of Unity Savings. Unity Savings
shall give Oak Hill Financial prompt notice of any such Acquisition Proposals.

         4.08 ADVICE OF CHANGES. Between the date hereof and the Effective Date,
Unity Savings shall advise Oak Hill Financial promptly, in writing, of any fact
which, if existing or known on the date hereof, would have been required to be
set forth or disclosed in or pursuant to this Agreement and any fact which, if
existing or known on the date hereof, would have made any of the representations
contained herein untrue. Prior to the Effective Date, Unity Savings shall
deliver to Oak Hill Financial a supplement to the Unity Disclosure Memorandum,
which shall contain a description of any and all such matters.

         4.09 CONFIDENTIALITY. From and after the date of this Agreement, Unity
Savings shall, and shall cause its respective Affiliates to, treat all

receive dividends from both Unity Savings and Oak Hill Financial during such
quarter.

to cause the Merger, and will take no action which would cause the Merger not to
qualify for treatment as a "reorganization" within the meaning of Section 368(a)
of the Internal Revenue Code for federal income tax purposes.

         4.12 POOLING. The accounting firm of Norman, Jones, Enlow and Co. has
reviewed the proposed Merger and knows of no reason why the Merger would not
qualify as a "pooling of interest" for accounting purposes. Unity Savings shall
not intentionally take or cause to be taken any action, whether before or after
the Effective Date, which would disqualify the Merger as a "pooling of
interests" for accounting purposes or as a "reorganization" within the meaning
of Section 368(a) of the Code.

Board of Directors
Unity Savings Bank of Southeastern Ohio
115 West Main Street
McArthur, OH 45651

Gentlemen:

         You have requested our opinion with respect to the fairness, from a
financial point of view, as of the date hereof, to the holders of common stock,
no par value ("Unity Common"), of Unity Savings Bank of Southeastern Ohio
("Unity") of the financial consideration as set forth in Section 8 (b)(i) of
the Agreement and Plan of Merger dated April 28, 1997, by and between Oak Hill
Financial Corp. ("Oak Hill") and Unity.

         The Agreement and Plan of Merger and the Supplemental Agreement dated
April 28, 1997 (together, the "Merger Agreement") provides for the merger (the
"Merger") of Unity with and into Oak Hill, pursuant to which, among other
things, at the Effective Time (as defined in the Merger Agreement), outstanding
shares of Unity Common will be exchanged for 8.5 shares (the "Exchange Ratio")
of common stock, $1.00 par value ("Oak Hill Common") of Oak Hill, subject to
adjustment, as set forth in Section 8 (b)(i) of the Agreement and Plan of
Merger. The terms and conditions of the merger are more fully set forth in the
Merger Agreement.

         McDonald & Company Securities, Inc., as part of its investment banking
business, is customarily engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.

         We have acted as Unity's financial advisor in connection with, and
have participated in certain negotiations leading to, the execution of the
Merger Agreement. In connection with rendering our opinion set forth herein, we
have among other things:

                  the years ended December 31, 1996, December 31, 1995 and
                  December 31, 1994, including the audited financial statements
                  contained therein, and Unity's Call Reports for the three
                  month period ended March 31, 1997;

         (ii)     Reviewed Oak Hill's Annual Reports to Shareholders and Annual
                  Reports on Form 10-KSB for each of the years ended December
                  31, 1996 and December 31, 1995, including the audited
                  financial statements contained therein, and Oak Hill's
                  unaudited financial statements for the three month period
                  ended March 31, 1997;

         (iii)    Reviewed certain other public and non-public information,
                  primarily financial in nature, relating to the respective
                  businesses, earnings, assets and prospects of Unity and Oak
                  Hill provided to us or publicly available;

         (iv)     Participated in meetings and telephone conferences with
                  members of senior management of Unity and Oak Hill concerning
                  the financial condition, business, assets, financial forecasts
                  and prospects of the respective companies, as well as other
                  matters we believed relevant to our inquiry;

         (v)      Reviewed certain stock market information for Unity Common and
                  Oak Hill Common, and compared it with similar information for
                  certain companies, the securities of which are publicly
                  traded;

         (vi)     Compared the results of operations and financial condition of
                  Unity and Oak Hill with that of certain companies which we
                  deemed to be relevant for purposes of this opinion;

         (vii)    Reviewed the financial terms, to the extent publicly
                  available, of certain acquisition transactions which we deemed
                  to be relevant for purposes of this opinion;

         (viii)   Reviewed the Merger Agreement and its schedules and exhibits
                  and certain related documents; and

         (ix)     Performed such other reviews and analyses as we have deemed
                  appropriate.

         In our review and analysis and in arriving at our opinion, we have
assumed and relied upon the accuracy and completeness of all of the financial
and other information reviewed by us and have relied upon the accuracy and
completeness of the representations, warranties and covenants of Unity and Oak
Hill contained in the Merger Agreement. We have not been engaged to undertake,
and have not assumed any responsibility for, nor have we conducted, an
independent investigation or verification of such matters. We have not been
engaged to and we have not conducted a physical inspection of any of the
assets, properties or facilities of either Unity or Oak Hill, nor have we made
or obtained or been furnished with any independent valuation or appraisal of
any of such assets, properties or facilities or any of the liabilities of
either Unity or Oak Hill. With respect to financial forecasts used in our
analysis, we have assumed that such forecasts have been reasonably prepared by
management of Unity and Oak Hill, as the case may be, on a basis reflecting the
best currently available estimates and judgments of the management of Unity and
Oak Hill, as to the future performance of Unity, Oak Hill, and Unity and Oak
Hill combined, as the case may be. We have not been engaged to assess the
reasonableness or achievability of such financial forecasts or the assumptions
on which they are based, and we express no view as to such financial forecasts
or assumptions. We have also assumed that all of the conditions to the
consummation of the Merger, as set forth in the Merger Agreement, would be
satisfied and that the Merger would be consummated on a timely basis in the
manner contemplated by the Merger Agreement, including the tax-free treatment
of the Merger to the holders of Unity Common.

         We will receive a fee for our services as financial advisor to Unity,
a substantial portion of which is contingent upon closing of the Merger. We
will also receive a fee for our services in rendering this opinion.

         In the ordinary course of business, we may actively trade securities
of Unity or Oak Hill for our own account and for the accounts of customers and,
accordingly, we may at any time hold a long or short position in such
securities. From time to time, we have also provided investment banking
services to Oak Hill, and served as managing underwriter for an initial public
offering of Oak Hill's Common. We received customary fees from Oak Hill for
these services. In addition, prior to our engagement to serve as Unity's
financial advisor, we participated in preliminary discussions with
representatives of Oak Hill and Unity concerning the financial aspect of a
transaction between the two companies.

         This opinion is based on economic and market conditions and other
circumstances existing on, and information made available as of, the date
hereof. In addition, our opinion is, in any event, limited to the fairness, as
of the date hereof, from a financial point of view, of the Exchange Ratio to
the holders of Unity Common, and does not address the underlying business
decision by Unity's Board of Directors to effect the Merger, does not compare
or discuss the

relative merits of any competing proposal or any other terms of the Merger, and
does not constitute a recommendation to any Unity shareholder as to how such
shareholder should vote with respect to the Merger. This opinion does not
represent an opinion as to what the value of Unity Common or Oak Hill Common
may be at the Effective Time of the Merger or as to the prospects of Unity's
business or Oak Hill's business.

         This opinion has been prepared solely for the confidential use of the
Board of Directors of Unity and will not be reproduced, summarized, described
or referred to or given to any other person without our prior written consent.
Notwithstanding the foregoing, this opinion may be included in the proxy
statement to be mailed to the holders of Unity Common in connection with the
Merger, provided that this opinion will be reproduced in such proxy statement
in full, and any description of or reference to us or our actions, or any
summary of the opinion in such proxy statement, will be in a form acceptable to
us and our counsel.

         Based upon and subject to the foregoing, it is our opinion that, as of
the date hereof, the Exchange Ratio is fair to the holders of Unity Common from
a financial point of view.

                                             Very truly yours,

Oak Hill Financial, Inc.

Jackson, Ohio  45640

Gentlemen:

         You have requested our opinion as to the fairness, from a financial
point of view, to the holders of shares of common stock (the "Oak Hill Common
Stock") of Oak Hill Financial, Inc. ("Oak Hill") of the consideration to be
paid by Oak Hill in the proposed acquisition (the "Acquisition") of Unity
Savings Bank, McArthur, Ohio ("Unity") by Oak Hill, pursuant to the Agreement
and Plan of Merger (the "Agreement") dated April 15, 1997. Unless otherwise
noted, all terms used herein shall have the same meaning as defined in the
Agreement.

         As more specifically set forth in the Agreement, and subject to a
number of conditions and procedures described in the Agreement, each of the
issued and outstanding shares of Unity Common Stock shall be converted into the
right to receive 8.5 shares (the "Exchange Ratio") of Oak Hill Common Stock. In
the event that the Average Closing Price (the average of daily average closing
bid and asked prices of Oak Hill Common Stock as reported on the Nasdaq
National Market System for 20 consecutive trading days three days prior to the
closing date) is greater than 115% of the Starting Price (the average of daily
average closing bid and asked prices of Oak Hill Common Stock as reported on
the Nasdaq National Market System for five consecutive trading days ending on
the Starting Date, which is the date of the Agreement), the Exchange Ratio will
be adjusted such that the consideration to be received by each shareholder of
Unity Common Stock shall be equal to 115% of the Starting Price.

         Trident Financial Corporation ("Trident") is a financial consulting
and investment banking firm experienced in the valuation of business
enterprises with considerable experience in the valuation of financial
institutions. Trident is not affiliated with Oak Hill or Unity, nor has Trident
been retained on a contingent fee basis.

         In connection with rendering our opinion, we have reviewed and
analyzed, among other things, the following (i) the Agreement; (ii) the
Prospectus/Proxy Statement/Information Statement; (iii) certain publicly
available information concerning Oak Hill, including the audited financial
statements of Oak Hill for each of the years in the three year period ended
December 31, 1996 and unaudited financial statements for the three months ended
March 31, 1997; (iv) certain publicly available information concerning Unity,
including the audited financial statements of Unity for each of the years in
the three year period ended December 31, 1996 and unaudited financial
statements for the three months ended March 31, 1997; (v) certain other



                                      C-1


<PAGE>   172



internal information, primarily financial in nature, concerning the business
and operations of Oak Hill and Unity furnished to us by Oak Hill and Unity for
purposes of our analysis; (vi) certain publicly available information with
respect to other companies that we believe to be comparable to Unity; and (vii)
certain publicly available information concerning the nature and terms of other
transactions that we consider relevant. We have also spoken with certain
officers and employees of Oak Hill, to discuss the foregoing as well as other
matters we believe relevant to our inquiry.

         In our review and analysis and in arriving at our opinion, we have
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided to us or publicly available and have not
attempted independently to verify any such information. We did not perform a
review of the loan portfolio, and we did not assess the adequacy of Unity's
loan loss reserves. We have not conducted a physical inspection of Unity's
properties or facilities, nor have we made or obtained any independent
evaluations or appraisals of any of such properties or facilities.

         In conducting our analysis and arriving at our opinion as expressed
herein, we have considered such financial and other factors as we have deemed
appropriate under the circumstances including, among others, the following: (i)
the historical and current financial condition and results of operations of Oak
Hill and Unity, including interest income, interest expense, net interest
income, net interest margin, interest sensitivity, non-interest income and
expense, earnings, dividends, book value, return on assets, return on equity,
capitalization, the amount and type of non-performing assets and the reserve
for loan losses; (ii) the business prospects of Oak Hill and Unity; (iii) the
economy of Oak Hill's and Unity's market areas, and (iv) the nature and terms
of certain other acquisition transactions that we believe to be relevant. We
have also taken into account our assessment of general economic, market,
financial and regulatory conditions and trends, as well as our knowledge of the
financial services industry, our experience in connection with similar
transactions, and our knowledge of securities valuation generally. Our opinion
necessarily is based upon conditions as they exist and can be evaluated on the
date hereof. Our opinion is, in any event, limited to the fairness, from a
financial point of view, of the consideration to be paid by Oak Hill in the
Acquisition and does not address Oak Hill's underlying business decision to
effect the Acquisition.

         Based upon and subject to the foregoing, we are of the opinion that
the consideration to be paid by Oak Hill in the Acquisition is fair, as of the
date hereof, from a financial point of view, to the shareholders of Oak Hill.

         This opinion is being delivered to the Board of Directors of Oak Hill
for its use and is not to be reproduced, disseminated or delivered to any third
party without the express written consent of Trident Financial Corporation,
except as required by law.

                                           Very truly yours,

               SECTION 1701.85 OF THE OHIO GENERAL CORPORATION LAW

        @1701.85 QUALIFICATION AND PROCEDURES FOR DISSENTING SHAREHOLDERS

(A)(1) A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, 1701.84 of the Revised Code, only in compliance with this
section.

   (2) If the proposal must be submitted to the shareholders of the corporation
involved, the dissenting shareholder shall be a record holder of the shares of
the corporation as to which he seeks relief as of the date fixed for the
determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the
date on which the vote on the proposal was taken at the meeting of the
shareholders, the dissenting shareholder shall deliver to the corporation a
written demand for payment to him of the fair cash value of the shares as to
which he seeks relief, which demand shall state his address, the number and
class of such shares, and the amount claimed by him as the fair cash value of
the shares.

   (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of merger
pursuant to section 1701.801 [1701.80.1] of the Revised code shall be a record
holder of the shares of the corporation as to which he seeks relief as of the
date on which the agreement of merger was adopted by the directors of that
corporation. Within twenty days after he has been sent the notice provided in
section 1701.80 or 1701.801 [1701.80.1] of the Revised Code, the dissenting
shareholder shall deliver to the corporation a written demand for payment with
the same information as that provided for in division (A)(2) of this section.

   (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.

   (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made. The corporation promptly shall return such endorsed certificates to
the dissenting shareholder. A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting shareholder
within

                                  D1 



<PAGE>   174

twenty days after the lapse of the fifteen-day period, unless a court for good
cause shown otherwise directs. If shares represented by a certificate on which
such a legend has been endorsed are transferred, each new certificate issued
for them shall bear a similar legend, together with the name of the original
dissenting holder of such shares. Upon receiving a demand for payment from a
dissenting shareholder who is the record holder of uncertificated securities,
the corporation shall make an appropriate notation of the demand for payment
in its shareholder records. If uncertificated shares for which payment has been
demanded are to be transferred, any new certificate issued for the shares shall
bear the legend required for certificated securities as provided in this
paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.

     (B) Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final orders in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505, of the

                                   D2



















<PAGE>   175
Revised Code. If, during the pendency of any proceeding instituted under this
section, a suit or proceeding is or has been instituted to enjoin or otherwise
to prevent the carrying out of the action as to which the shareholder has
dissented, the proceeding instituted under this section shall be stayed until
the final determination of the other suit or proceeding. Unless any provision
in division (D) of this section is applicable, the fair cash value of the
shares that is agreed upon by the parties or fixed under this section shall be
paid withing thirty days after the date of final determination of such value
under this division, the effective date of the amendment to the articles, or
the consummation of the other action involved, whichever occurs last. Upon the
occurrence of the last such event, payment shall be made immediately to a
holder of uncertificated securities entitled to such payment. In the case of
holders of shares represented by certificates, payment shall be made only upon
and simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.

   (C) If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and,
in the case of a merger pursuant to section 1701.80 or 1701.801 [1701.80.1] of
the Revised Code, fair cash value as to shareholders of a constituent
subsidiary corporation shall be determined as of the day before the adoption of
the agreement of merger by the directors of the particular subsidiary
corporation. The fair cash value of a share for the purposes of this section is
the amount that a willing seller who is under no compulsion to sell would be
willing to accept and that willing buyer who is under no compulsion to purchase
would be willing to pay, but in no event shall the fair cash value of a share
exceed the amount specified in the demand of the particular shareholder. In
computing such fair cash value, any appreciation or depreciation in market value
resulting from the proposal submitted to the directors or to the shareholders
shall be excluded.

   (D)(1) The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:

        (a) The dissenting shareholder has not complied with this section,
unless the corporation by its directors waives such failure;

        (b) the corporation abandons the action involved or is finally enjoined
or prevented from carrying it out, or the shareholders rescind their adoption
of the action involved;

        (c) The dissenting shareholder withdraws his demand, with the consent
of the corporation by its directors;

        (d) The corporation and the dissenting shareholder have not come to an
agreement as to the fair cash value per share, and neither the shareholder nor
the corporation has filed or joined in a complaint under division (B) of this
section within the period provided in that division.    

                                      D3
<PAGE>   176
        (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.

   (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair
cash value of the shares. If the right to receive fair cash value is terminated
other than by the purchase of the shares by the corporation, all rights of the
holder shall be restored and all distributions which, except for the
suspension, would have been made shall be made to the holder of record of the
shares at the time of termination.

                     INFORMATION NOT REQUIRED IN PROSPECTUS



ITEM 20.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.


         (a) Article VI of the Company's Regulations provides that the Company
shall indemnify any person who was or is a party or is threatened to be made a
party to any action (other than an action by or in the right of the Company) by
reason of the fact that the person was or is a director of the Company; or while
a director of the Company such person was or is serving at the request of the
Company as a director, officer, or in some other agency capacity for another
entity. The Company may indemnify any person who was or is a party or is
threatened to be made a party to any action (other than an action by or in the
right of the Company) by reason of the fact that the person was or is an
officer, employee or agent of the Company, or while an officer, employee or
agent of the Company was or is serving at the request of the Company as a
director, officer or in some other agency capacity for another entity.
Indemnification covers expenses (including attorney's fees), judgments, fines
and amounts paid in settlements if such an aforementioned person acted in good
faith and in a manner in which they reasonably believed to be in or not opposed
to the best interests of the Company; and, with respect to a criminal
proceeding, the person had no reasonable cause to believe that the conduct was
unlawful. The termination of an action by judgment, order, settlement or
conviction, or upon a plea of nolo contendere, shall not, by itself, create a
presumption about a person's state of mind.


         The Company may indemnify any person who was or is a party or is
threatened to be made a party in an action by or in the right of the Company to
procure a judgment in its favor by reason of the fact that the person is a
director, officer, employee or agent, or is serving at the request of the
Company as a director, officer or in some other agency capacity for another
entity. In actions by the Company, indemnification covers expenses (including
attorney's fees) incurred by a person in connection with defense or settlement
of such action if they acted in good faith and in a manner reasonably believed
to be in or not opposed to the best interests of the Company. No indemnification
shall be made in respect of (1) any action as to which such person is adjudged
to be liable for negligence or misconduct in the performance of their duties,
unless and only to the extent the court in which such action was brought
determines upon application that such person is reasonably entitled to indemnity
for such expenses as the court shall deem proper; or (2) any action in which the
only liability asserted against a director is pursuant to Section 1701.95 of the
Ohio Revised Code dealing with liability for unlawful loans, dividends or
distributions.

         Any indemnification shall be made by the Company only as authorized in
the specific case upon a determination that the indemnification was proper
because the person met the applicable standard of conduct set forth above. Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum of disinterested directors; (2) in a written opinion by independent
counsel; (3) by the shareholders; or (4) by the court where the action was
brought. Any determination made by the disinterested directors or independent
counsel shall be properly communicated to the person who threatened or brought
the action by or in the right of the Company. Such person shall have the right,
within ten days after notification, to petition the court to review the
reasonableness of such determination. To the extent that a director or other
person in an agency capacity has been successful on the merits or in defense of
an action referred to above, that person shall be indemnified against expenses
(including attorney's fees) reasonably incurred in connection with the action;
this type of indemnification does not require an authorized determination by the
Company.

         Expenses (including attorney's fees) incurred by a director in
defending an action referred to above, except where the liability asserted
against a director is pursuant to Section 1701.95 of the Ohio Revised Code,
shall be paid by the Company as they are incurred in advance of the final
disposition of the action, if the director agrees to repay such amount if it is
proved that the director's action or failure to act was undertaken with
deliberate intent to cause injury to the Company or with reckless disregard for
the best interests of the Company. Expenses (including attorney's fees) incurred
by a director or other person in an agency capacity in defending an action
referred to above, including an action brought against a director pursuant to
Section 1701.95 of the Ohio Revised Code, may be paid by the Company as


                                      II-1
<PAGE>   178
incurred before final disposition of the action as authorized by the directors
if such person agrees to repay the Company if it is ultimately determined that
the person is not entitled to be indemnified.

         The indemnification authorized by Article VI is not exclusive of, and
is in addition to, any other rights granted to those seeking indemnification
under the Company's regulations, common law and corporation law of the State of
Ohio, or vote of shareholders or disinterested directors. Indemnification rights
shall continue in the person who has ceased to be affiliated with the Company
and shall inure to such person's heirs, executors and administrators.

         The Company may purchase insurance on behalf of any person who was or
is a director, officer, employee or agent of the Company, or was or is serving
at the request of the Company as director, officer or in some other agency
capacity for another entity, against liability that is asserted or incurred by
such person in any such capacity, whether or not the Company has the power to
indemnify such person against liability under the provisions of Article VI.
Under Section 1701.13 of the Ohio General Corporation Law, a corporation may
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee, or agent of the corporation, or who, while serving
in such capacity, is or was at the request of the corporation, a director,
officer, employee or agent of another corporation or legal entity or of an
employee benefit plan, against liability asserted against or incurred by such
person in any such capacity whether or not the corporation would have the power
to provide indemnity under Section 1701.13 of the Ohio General Corporation Law.

         The above discussion of the Company's Regulations and of Section
1701.13 of the Ohio General Corporation Law is not intended to be exhaustive and
is respectively qualified in its entirety by such Regulations and statute.

ITEM 22.          UNDERTAKINGS.

         The undersigned Registrant hereby undertakes: (1) to file during any
period in which offers or sales are being made, a post effective amendment to
this registration statement: (i) to include any prospectus required by section
10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume or securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation
from the low or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the Commission pursuant to Rule
424(b) if, in the aggregate, the changes in volume and price represent no more
than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
(iii) to include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement; (2) that for
the purpose of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof; (3)
to remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of the Rule 145(c),
the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.

         The Registrant undertakes that every prospectus (i) that is filed
pursuant to the immediately preceding paragraph, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the Registration Statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of


                                      II-4
<PAGE>   181
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Registration Statement, within one business
day of receipt of such request, and to send the incorporated documents by first
class mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.

         The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.


                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the

         Re:  Merger of Unity Savings Bank into Oak Hill Banks

Gentlemen:

         This opinion is furnished with respect to the Registration Statement
on Form S-4 (the "Registration Statement") being filed by Oak Hill Financial,
Inc. (the "Company") with the Securities and Exchange Commission related to the
registration of a maximum of 792,625 shares of Company common stock, without
par value (the "Stock"), to be issued in connection with the proposed merger
(the "Merger") of Unity Savings Bank, an Ohio savings bank ("Unity"), with and
into Oak Hill Banks, a banking corporation chartered under the law of Ohio and
a wholly owned subsidiary of the Company (the "Bank").

         We are counsel for the Company and have participated in the
preparation of the Registration Statement.  We have reviewed the Agreement and
Plan of Merger and the Supplemental Agreement thereto, both dated as of April
28, 1997, among the Company, the Bank and Unity (the "Merger Agreement"), the
Company's Amended and Restated Articles of Incorporation and Amended and
Restated Code of Regulations, the corporate action taken to date in connection
with the Registration Statement and the issuance and sale of the Stock, and
such other documents and authorities as we deem relevant for the purpose of
this opinion.

         Based upon the foregoing, we are of the opinion that:

         (a)      upon the proper approval of the Merger by the shareholders of
                  the Company and Unity and the filing of a certificate of
                  merger with the Ohio Secretary of State;

         (b)      upon compliance with the Securities Act of 1933, as amended,
                  and with the Securities or "blue sky" laws of the states in
                  which the Stock is to be offered for sale; and

         (c)      upon satisfaction of all of the conditions stated in the
                  Merger Agreement and at the "Effective Time," as defined in
                  the Merger Agreement;

the Stock, when issued and delivered as provided in the Merger Agreement in
accordance with the resolutions heretofore adopted by the Board of Directors
and shareholders of the Company, will be legally issued, fully paid, and
nonassessable.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement.

Gentlemen:

         We have acted as counsel to Oak Hill Financial, Inc., an Ohio
corporation ("Oak Hill Financial") in connection with the proposed statutory
merger (the "Merger") of Unity Savings Bank, a savings bank that is chartered
under the laws of Ohio ("Unity Savings"), with and into Oak Hill Banks, a
banking corporation chartered under the laws of Ohio, and a wholly owned
subsidiary of Oak Hill Financial. Pursuant to the Merger, the shareholders of
Unity Savings will receive common shares, $1.00 par value, of Oak Hill Financial
("Oak Hill Financial Shares") subject to the Agreement and Plan of Merger and
Supplemental Agreement, both dated as of April 28, 1997, between Unity Savings,
Oak Hill Financial and Oak Hill Banks (the "Merger Agreement"), in exchange for
their outstanding common shares of Unity Savings ("Unity Savings Shares"). At
your request, we are rendering our opinion concerning certain federal income tax
consequences of the Merger. Terms not otherwise defined herein shall have the
same meaning as when used in the Merger Agreement.

         In that connection, we have examined and relied upon originals, or
copies certified or otherwise identified to our satisfaction, of such records,
documents, and other instruments, and such other matters of fact and law, as we
have considered necessary or appropriate for the purposes of this opinion,
including an examination of: (i) the Merger Agreement and the other documents
and agreements referred to therein; and (ii) the Joint Proxy
Statement/Prospectus (the "Prospectus") relating to the Merger and included in
the Registration Statement of the Oak Hill Financial on Form S-4 (the
"Registration Statement") filed by the Oak Hill Financial with the Securities
and Exchange

Commission. In our examination, we have assumed the legal capacity of all
natural persons, the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to the original documents
of all documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents.

         For purposes of the opinions set forth below, we have assumed and are
relying upon the accuracy and completeness of the statements and representations
(which statements and representations we have neither investigated nor verified,
and upon which we are entitled to rely) contained, respectively, in certain
certificates of the officers of the Oak Hill Financial, Oak Hill Banks and Unity
Savings. We have also assumed that the transactions contemplated by the Merger
Agreement will be consummated in accordance with the Merger Agreement, the
Merger will constitute a statutory merger pursuant to the applicable provisions
of the law of the State of Ohio, and the facts, statements, and other
information contained in the Prospectus relating to the Merger are true,
correct, and complete in all material respects.

         The opinions set forth below are based upon, and the section numbers
cited herein refer to, the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury Regulations promulgated thereunder, the administrative
interpretations thereof and the judicial decisions with respect thereto, all as
currently in effect, and are further based upon the continued accuracy and
completeness of the documents, certifications, and representations referred to
in the two preceding paragraphs as of the Effective Time.

         In reliance on the assumptions and the representations set forth above,
and further assuming that the shareholders of Unity Savings do not, for a
sufficient period of time to meet the continuity of interest requirements for a
reorganization, sell, exchange, transfer by gift, or otherwise dispose of a
number of Oak Hill Financial Shares received in the Merger that would reduce the
ownership of Oak Hill Financial Shares by the former shareholders of Unity
Savings to a number of shares having a value, as of the date of the Merger, of
less than 50 percent of the total value of all the formerly outstanding Unity
Savings Shares as of the same date, we are of the opinion that:

         (1)     The Merger will constitute a reorganization within the meaning
                 of Section 368(a)(1)(A) and (a)(2)(D) of the Code.

         (2)     Each of Unity Savings, Oak Hill Financial and Oak Hill Banks
                 will be a "party to a reorganization" within the meaning of
                 Section 368(b) of the Code.

         (3)     The discussion contained in the Registration Statement under
                 the caption "The Merger - Certain Federal Income Tax
                 Consequences" represents our opinion as to the material
                 federal income tax consequences of the Merger.

         We have given this opinion in connection with the transactions
contemplated thereby and such opinion is not to be relied upon for any other
purpose. This opinion may not be applicable to all shareholders, including,
without limitation, (1) a Unity Savings shareholder whose Unity Savings Shares
are not held as a capital asset; or (2) a Unity Savings shareholder who is
subject to special treatment under the Code, including without limitation, an
insurance company, a dealer in securities, a financial institution, a tax-exempt
investor, a foreign shareholder, or a shareholder who is subject to the "golden
parachute" provisions of the Code. This opinion further assumes no shareholder
acquired Unity Savings Shares in contemplation of or to effectuate the Merger.

         In addition to the assumptions and exclusions above, no opinion is
expressed herein concerning the effect of state, local, and foreign tax laws.
Furthermore, no opinion is expressed herein about the tax treatment of the
transaction under other provisions of the Code or the Treasury Regulations
issued thereunder or about the tax treatment of any conditions existing at the
time of, or effects resulting from, the transaction that are not specifically
addressed by the foregoing opinion, including, without limitation, the exchange
of any Unity Savings Shares in the Merger that were acquired by the holder
pursuant to an employee stock option or employee stock purchase plan or
otherwise as compensation.

         You should be aware that this opinion represents our conclusions as to
the application of existing law and is based on the certifications and
representations given as of the date hereof. The statutory provisions,
regulations, interpretations, and other authorities upon which our opinion is
based are subject to change, and such changes could apply retroactively. A
material change in any of the authorities upon which our opinion is based could
affect our conclusions herein. In addition, no advance ruling has been obtained
from the Internal Revenue Service ("Service") regarding the Merger. An opinion
of counsel represents counsel's best legal judgement, but has no binding effect
or official status of any kind. Accordingly, there can be no assurance that the
Service or Courts will not take positions contrary to the opinions stated above.
No person other than the addressees named herein may rely on this opinion for
any purpose.

         We hereby consent to the use of this opinion as an exhibit to the
Registration Statement. By giving this consent, however, we do not admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Commission thereunder.

                                   Very truly yours,

         8. TERMINATION.

                  (a) Employee's employment under this Agreement shall terminate
automatically upon Employee's death or disability. For purposes of this
Agreement, Employee shall be deemed to be disabled if, by reason of injury or
illness (mental or physical), he has been or will be unable to perform his
duties under this Agreement for a continuous period of 120 days or for an
aggregate of 180 days in any 365-day period.

                  (b) Employer may, at its option, terminate Employee's
employment under this Agreement immediately, without notice to Employee, upon
the happening of any of the following events, any of which shall constitute a
termination "for cause" for purposes of this Agreement:

                           (i) any material breach of this Agreement by
         Employee;

                           (ii) any act of fraud, embezzlement, or other willful
         misconduct by Employee in relation to the business or affairs of
         Employer or gross negligence by Employee in the performance of his

                           (iii) any other illegal (other than traffic
         violations or similar minor offenses) conduct on the part of Employee.

                  (c) Employee may terminate his employment under this Agreement

         9. EFFECT OF TERMINATION BY EMPLOYER WITHOUT CAUSE. If, prior to the
end of the Initial Term, Employer terminates the employment of Employee without
cause (as defined in Section 8 above), Employer will pay to such Employee the
sum equal to the total of the unpaid salary installment payments remaining to be
paid during the Initial Term, which will be payable in equal monthly
installments commencing on the date of such termination and continuing monthly
thereafter until the end of the Initial Term, and Employer will provide to the
Employee at Employer's expense for the remainder of the Initial Term, health,
life, disability and other benefits substantially equal to those provided to the
Employee at termination. Such payments and benefits shall be in lieu of any
other severance or compensation that might otherwise be payable to such Employee
under such Employee's Employment Agreement or otherwise, except as specifically
provided in paragraph 4(b) above. The Employee shall not be required to mitigate
the amount of any payment provided for in this Section 9 by seeking other
employment or otherwise.

         10. NONASSIGNABILITY. Neither party may assign this Agreement to a
third party without the written consent of the other party; provided, however,
that Employer may assign this Agreement without the consent of Employee to any
affiliate of Employer.

         11. AGREEMENT COMPLETE; AMENDMENTS. This instrument contains the entire
agreement of the parties with respect to the subject matter hereof. It may not
be amended, supplemented, or otherwise modified, except by an agreement in

                    EXECUTIVE SALARY CONTINUATION AGREEMENT
                    ---------------------------------------

          The Agreement, made and entered into this 7th day of December, 1994
by and between Unity Savings Bank, an Ohio Bank (hereinafter called "the
Bank"), and David Bruce Knox (hereinafter called "the Executive").

                                  WITNESSETH:
                                  -----------

          The Executive has been and continues to be a valued Executive of the
Bank, and is now serving the Bank as its Executive Vice President; and,

          It is the consensus of the Board of Directors that the Executive's
services to the Bank in the past have been of exceptional merit and have
constituted an invaluable contribution to the general welfare of the Bank and
in bringing it to its present status of operating efficiency, and its present
position in its field of activity; and,

          The experience of the Executive, his knowledge of the affairs of the
Bank, his reputation and contacts in the industry are so valuable that
assurance of his best continued interests to the Bank to arrange terms of
continued employment for the Executive so as to reasonably assure his remaining
in the Bank's employment during his lifetime or until the age of retirement;
and,

          It is the desire of the Bank that his services be retained as herein
provided; and,

          The Executive is willing to continue in the employ of the Bank
provided the Bank agrees to pay to him or his beneficiaries certain benefits in
accordance with the terms and conditions hereinafter set forth:

          Accordingly, it is the desire of the Bank and the Executive to enter
into this Agreement under which the Bank will agree to make certain payments to
the Executive at retirement or his beneficiary in the event of his premature
death while employed by the Bank; and,

          Furthermore, it is the intent of the parties hereto that this
Agreement be considered an unfunded arrangement maintained primarily to provide
supplemental benefits for the Executive, as a member of a select group of
management or highly compensated employees of the Bank for the purposes of the
Employee Retirement Income Security Act of 1974, (ERISA):

          Now therefore, in consideration of services performed in the past and
to be performed in the future as well as of the mutual promises and covenants
herein contained it is agreed as follows:

I.        EMPLOYMENT
          ----------

          The Bank agrees to employ the Executive in such capacity as the Bank
          may from time to time determine. The Executive will continue in the
          employ of the Bank in such capacity and with such duties and
          responsibilities as may be assigned to him, and with such


<PAGE>   2



          compensation as may be determined from time to time by the Board of
          Directors of the Bank. Active employment shall include temporary
          disability not to exceed six months and other "leave of absences"
          specifically granted by the Board of Directors.

II.       FRINGE BENEFITS
          ---------------

          The salary continuation benefits provided by this Agreement are
          granted by the Bank as a fringe benefit to the Executive and are not
          part of any salary reduction plan or an arrangement deferring a bonus
          or a salary increase. The Executive has no option to take any current
          payment or bonus in lieu of these salary continuation benefits except
          as set forth hereinafter.

III.      RETIREMENT DATE
          ---------------

          If the Executive remains in the continuous employ of the Bank, he
          shall retire from active employment with the Bank on the December
          31st nearest his sixty-fifth (65th) birthday.

IV.       RETIREMENT BENEFIT AND POST-RETIREMENT DEATH BENEFIT
          ----------------------------------------------------

          Commencing with the first day of the month following the date of
          retirement, (Paragraph III above), the Bank shall pay the Executive
          an annual benefit equal to $36,000 in equal monthly installments (of
          1/12 of the annual benefit) for a period of two hundred twelve (212)
          months, provided that if less than two hundred twelve (212) such
          monthly payments have been made prior to the death of the Executive,
          the Bank shall continue such monthly payments to whomever the
          Executive shall have designated in writing and filed with the Bank,
          until the full number of two hundred twelve (212) monthly payments
          have been made. In the absence of any effective designation of
          beneficiary, any such amounts becoming due and payable upon the death
          of the Executive shall be payable to the duly qualified executor or
          administrator of his estate.

V.        DEATH BENEFIT PRIOR TO RETIREMENT
          ---------------------------------

          In the event the Executive should die while actively employed by the
          Bank at any time after the date of this Agreement but prior to his
          attaining the age of sixty-five (65) years (or such later date as may
          be agreed upon), the Bank will pay an annual benefit equal to $67,483
          in equal monthly installments (each equal to 1/12 of the annual
          benefit) for a period of one hundred eighty (180) months to such
          individual or individuals as the Executive may have designated in
          writing and filed with the Bank. The said monthly payments shall
          begin the first day of the third month following the month of the
          decease of the Executive. In the absence of any effective designation
          of beneficiary, any such amounts becoming due and payable upon the
          death of the Executive shall be payable to the duly qualified
          executor or administrator of his estate. Provided, however, that
          anything hereinabove to the contrary



                                       2


<PAGE>   3



          notwithstanding, no death benefit shall be payable hereunder if it is
          determined that the Executive's death was caused by suicide on or
          before June 9, 1996.

VI.       BENEFIT ACCOUNTING
          ------------------

          The Bank shall account for this benefit using the regulatory
          accounting principles of the Bank's primary federal regulator. The
          Bank shall establish an accrued liability retirement account for the
          Executive into which appropriate reserves shall be accrued in the
          amount determined by the Bank's certified public accounting firm.

VII.      VESTING
          -------

          The Executive's interest in the benefits shall be vested at a rate of
          ten percent (10%) per year of service subsequent to the effective
          date of this agreement.

VIII.     OTHER TERMINATION OF EMPLOYMENT
          -------------------------------

          In the event that the employment of the Executive shall terminate
          prior to retirement from active employment, as provided in Paragraph
          III, by his voluntary action, or by his discharge by the Bank, the
          Bank shall pay to the Executive as severance compensation an amount
          of money equal to the accrued balance of the Executive's liability
          reserve account. This severance compensation shall be paid in one
          hundred eighty (180) equal annual installments with interest equal to
          the one year treasury bill as the date of termination.

          In the event the Executive's death should occur after such severance
          but prior to the completion of the monthly payments provided for in
          this Paragraph VIII, the remaining installments shall be paid to such
          individual or individuals as the Executive may have designated in
          writing, and filed with the Bank. In the absence of any effective
          designation of beneficiary, any such amounts shall be payable to the
          duly qualified executor or administrator of his estate.

IX.       PARTICIPATION IN OTHER PLANS
          ----------------------------

          The benefits provided hereunder shall be in addition to the
          Executive's annual salary as determined by the Board of Directors,
          and shall not affect the right of the Executive to participate in any
          current or future Bank Retirement Plan, group insurance, bonus, or in
          any supplemental compensation arrangement which constitutes a part of
          the Bank's regular compensation structure.

X.        CHANGE IN CONTROL
          -----------------

          In the event there is a change in control of the ownership of the
          Bank the Executive shall become one hundred percent (100%) vested for
          the purposes of Paragraph VIII hereinabove.



                                       3


<PAGE>   4



          Change in control is defined for these purposes as the cumulative

          ------------

          It is agreed that neither the Executive, nor his spouse, nor any
          other designee, shall have any right to commute, sell, assign,
          transfer or otherwise convey the right to receive any payments
          hereunder, which payments and the right thereto are expressly
          declared to be non-assignable and non-transferable; and, in the event
          of any attempted assignment or transfer, the Bank shall have no
          further liability hereunder.

XII.      RESTRICTIONS ON FUNDING
          -----------------------

          The Bank shall have no obligation to set aside, earmark, or entrust
          any fund or money with which to pay its obligations under this
          Agreement. The Bank reserves the absolute right at its sole
          discretion to either fund the obligations undertaken by this
          Agreement or to refrain from funding the same and determine the
          extent, nature, and method of such funding.

XIII.     GENERAL ASSETS OF THE BANK
          --------------------------

          The rights of the Executive under this Agreement and of any
          beneficiary of the Executive shall be solely those of an unsecured
          creditor of the Bank. If the Bank shall acquire an insurance policy
          or any other asset in connection with the liabilities assumed by it
          hereunder, it is expressly understood and agreed that neither the
          Executive nor any beneficiary of the Executive shall have any right
          with respect to, or claim against, such policy or other asset. Such
          policy or asset shall not be deemed to be held under any trust for
          the benefit of the Executive or his beneficiaries or to be held in
          any way as collateral security for the fulfilling of the obligations
          of the Bank under this Agreement. It shall be, and remain, a general,
          unpledged, unrestricted asset of the Bank and the Executive or any of
          his beneficiaries shall not have a greater claim to the insurance
          policy or other assets, or any interest in either of them, than any
          other general creditor of the Bank.

XIV.      REORGANIZATION
          --------------

          The Bank will not merge or consolidate with any other company or
          organization, or permit its business activities to be taken over by
          any other organization, unless the new entity expressly acknowledges
          its obligations under this Agreement and abide by its terms.

XX.       CLAIMS PROCEDURE AND ARBITRATION
          --------------------------------

          A.       Named Fiduciary and Plan Administrator
                   --------------------------------------

                   The "Named Fiduciary and Plan Administrator" of this plan
                   shall be David Bruce Knox until his resignation or removal
                   by the Board of Directors. As Named Fiduciary for the
                   management, control and administration of the Executive
                   Salary Continuation Agreement as established herein, he may
                   delegate to others certain aspects of the management and
                   operation responsibilities of the plan including the
                   employment of advisors and the delegation of ministerial
                   duties to qualified individuals.

          B.       In the event a dispute arises over benefits under this Plan
                   Agreement and benefits are not paid to the Executive (or to
                   his beneficiary(ies) in the case of the Executive's death)
                   and such claimants feel they are entitled to receive such
                   benefits, then a written claim must be made to the Fiduciary
                   and Administrator named above within sixty (60) days from
                   the date payments are refused. The Plan Fiduciary and
                   Administrator and the Bank shall review the written claim
                   and if the claim is denied,



                                       5


<PAGE>   6

                   in whole or in part, they shall provide in writing within
                   ninety (90) days of receipt of such claim their specific
                   reasons for such denial, reference to the provisions of this
                   Agreement upon which the denial is based and any additional
                   material or information necessary to perfect the claim. Such
                   written notice shall further indicate the additional steps
                   to be taken by claimants if a further review of the claim
                   denial is desired. A claim shall be deemed denied if the
                   Plan Fiduciary and Administrator fails to take any action
                   within the aforesaid ninety-day period.

                   If claimants desire a second review, they shall notify the
                   Plan Fiduciary and Administrator in writing within sixty
                   (60) days of the first claim denial. Claimants may review
                   the Plan Agreement or any documents relating thereto and
                   submit any written issues and comments they may feel
                   appropriate. In its sole discretion, the Plan Fiduciary and
                   Administrator shall then review the second claim and provide
                   a written decision within sixty (60) days of receipt of such
                   claim. This decision shall likewise state the specific
                   reasons for the decision and shall include reference to
                   specific provisions of the Plan Agreement upon which the
                   decision is based.

                   If claimants continue to dispute the benefit denial based
                   upon completed performance of the Agreement or the meaning
                   and effect of the terms and conditions thereof, then
                   claimants may submit the dispute to a Board of Arbitration
                   for final arbitration. Said Board shall consist of one
                   member selected by the Bank, one member selected by
                   claimant, and the third member selected by the first two
                   members. The Board shall operate under any generally
                   recognized set of arbitration rules. The parties hereto
                   agree that they and their heirs, personal representatives,
                   successors and assigns shall be bound by the decision of
                   such Board with respect to any controversy properly
                   submitted to it for determination.

                   Where a dispute arises as to the Bank's discharge of the
                   Executive "for cause", such dispute shall likewise be
                   submitted to arbitration as above described and the parties
                   hereto agree to be bound by the decision thereunder.

          In witness whereof, the Bank has caused this Agreement to be signed
in its corporate name by its duly authorized officers, and the Executive
hereunto set his hand, all on the day and year first above written.

                    EXECUTIVE SALARY CONTINUATION AGREEMENT
                    ---------------------------------------

          The Agreement, made and entered into this 7th day of December , 1994
by and between Unity Savings Bank, an Ohio Bank (hereinafter called "the
Bank"), and George Knox (hereinafter called "the Executive").

                                  WITNESSETH:
                                  -----------

          The Executive has been and continues to be a valued Executive of the
Bank, and is now serving the Bank as its President; and,

          It is the consensus of the Board of Directors that the Executive's
services to the Bank in the past have been of exceptional merit and have
constituted an invaluable contribution to the general welfare of the Bank and
in bringing it to its present status of operating efficiency, and its present
position in its field of activity; and,

          The experience of the Executive, his knowledge of the affairs of the
Bank, his reputation and contacts in the industry are so valuable that
assurance of his best continued interests to the Bank to arrange terms of
continued employment for the Executive so as to reasonably assure his remaining
in the Bank's employment during his lifetime or until the age of retirement;
and,

          It is the desire of the Bank that his services be retained as herein
provided; and,

          The Executive is willing to continue in the employ of the Bank
provided the Bank agrees to pay to him or his beneficiaries certain benefits in
accordance with the terms and conditions hereinafter set forth:

          Accordingly, it is the desire of the Bank and the Executive to enter
into this Agreement under which the Bank will agree to make certain payments to
the Executive at retirement or his beneficiary in the event of his premature
death while employed by the Bank; and,

          Furthermore, it is the intent of the parties hereto that this
Agreement be considered an unfunded arrangement maintained primarily to provide
supplemental benefits for the Executive, as a member of a select group of
management or highly compensated employees of the Bank for the purposes of the
Employee Retirement Income Security Act of 1974, (ERISA):

          Now therefore, in consideration of services performed in the past and
to be performed in the future as well as of the mutual promises and covenants
herein contained it is agreed as follows:

I.        EMPLOYMENT
          ----------

          The Bank agrees to employ the Executive in such capacity as the Bank
          may from time to time determine. The Executive will continue in the
          employ of the Bank in such capacity and with such duties and
          responsibilities as may be assigned to him, and with such


<PAGE>   2



          compensation as may be determined from time to time by the Board of
          Directors of the Bank. Active employment shall include temporary
          disability not to exceed six months and other "leave of absences"
          specifically granted by the Board of Directors.

II.       FRINGE BENEFITS
          ---------------

          The salary continuation benefits provided by this Agreement are
          granted by the Bank as a fringe benefit to the Executive and are not
          part of any salary reduction plan or an arrangement deferring a bonus
          or a salary increase. The Executive has no option to take any current
          payment or bonus in lieu of these salary continuation benefits except
          as set forth hereinafter.

III.      RETIREMENT DATE
          ---------------

          If the Executive remains in the continuous employ of the Bank, he
          shall retire from active employment with the Bank on the December
          31st nearest his sixty-fifth (65th) birthday.

IV.       RETIREMENT BENEFIT AND POST-RETIREMENT DEATH BENEFIT
          ----------------------------------------------------

          Commencing with the first day of the month following the date of
          retirement, (Paragraph III above), the Bank shall pay the Executive
          an annual benefit equal to $36,000 in equal monthly installments (of
          1/12 of the annual benefit) for a period of two hundred twelve (212)
          months, provided that if less than two hundred twelve (212) such
          monthly payments have been made prior to the death of the Executive,
          the Bank shall continue such monthly payments to whomever the
          Executive shall have designated in writing and filed with the Bank,
          until the full number of two hundred twelve (212) monthly payments
          have been made. In the absence of any effective designation of
          beneficiary, any such amounts becoming due and payable upon the death
          of the Executive shall be payable to the duly qualified executor or
          administrator of his estate.

V.        DEATH BENEFIT PRIOR TO RETIREMENT
          ---------------------------------

          In the event the Executive should die while actively employed by the
          Bank at any time after the date of this Agreement but prior to his
          attaining the age of sixty-five (65) years (or such later date as may
          be agreed upon), the Bank will pay an annual benefit equal to $67,483
          in equal monthly installments (each equal to 1/12 of the annual
          benefit) for a period of one hundred eighty (180) months to such
          individual or individuals as the Executive may have designated in
          writing and filed with the Bank. The said monthly payments shall
          begin the first day of the third month following the month of the
          decease of the Executive. In the absence of any effective designation
          of beneficiary, any such amounts becoming due and payable upon the
          death of the Executive shall be payable to the duly qualified
          executor or administrator of his estate. Provided, however, that
          anything hereinabove to the contrary



                                       2


<PAGE>   3



          notwithstanding, no death benefit shall be payable hereunder if it is
          determined that the Executive's death was caused by suicide on or
          before June 9, 1996.

VI.       BENEFIT ACCOUNTING
          ------------------

          The Bank shall account for this benefit using the regulatory
          accounting principles of the Bank's primary federal regulator. The
          Bank shall establish an accrued liability retirement account for the
          Executive into which appropriate reserves shall be accrued in the
          amount determined by the Bank's certified public accounting firm.

VII.      VESTING
          -------

          The Executive's interest in the benefits shall be vested at a rate of
          ten percent (10%) per year of service subsequent to the effective
          date of this agreement.

VIII.     OTHER TERMINATION OF EMPLOYMENT
          -------------------------------

          In the event that the employment of the Executive shall terminate
          prior to retirement from active employment, as provided in Paragraph
          III, by his voluntary action, or by his discharge by the Bank, the
          Bank shall pay to the Executive as severance compensation an amount
          of money equal to the accrued balance of the Executive's liability
          reserve account. This severance compensation shall be paid in one
          hundred eighty (180) equal annual installments with interest equal to
          the one year treasury bill as the date of termination.

          In the event the Executive's death should occur after such severance
          but prior to the completion of the monthly payments provided for in
          this Paragraph VIII, the remaining installments shall be paid to such
          individual or individuals as the Executive may have designated in
          writing, and filed with the Bank. In the absence of any effective
          designation of beneficiary, any such amounts shall be payable to the
          duly qualified executor or administrator of his estate.

IX.       PARTICIPATION IN OTHER PLANS
          ----------------------------

          The benefits provided hereunder shall be in addition to the
          Executive's annual salary as determined by the Board of Directors,
          and shall not affect the right of the Executive to participate in any
          current or future Bank Retirement Plan, group insurance, bonus, or in
          any supplemental compensation arrangement which constitutes a part of
          the Bank's regular compensation structure.

X.        CHANGE IN CONTROL
          -----------------

          In the event there is a change in control of the ownership of the
          Bank the Executive shall become one hundred percent (100%) vested for
          the purposes of Paragraph VIII hereinabove.



                                       3


<PAGE>   4



          Change in control is defined for these purposes as the cumulative
          transfer to any party other than current shareholders, from the date
          of this Agreement, of more than fifty percent (50%) of the stock of
          the Bank. For these purposes, transactions between family members
          shall be disregarded and transfers on account of death or as a gift
          shall also be disregarded.

XI.       ALIENABILITY
          ------------

          It is agreed that neither the Executive, nor his spouse, nor any
          other designee, shall have any right to commute, sell, assign,
          transfer or otherwise convey the right to receive any payments
          hereunder, which payments and the right thereto are expressly
          declared to be non-assignable and non-transferable; and, in the event
          of any attempted assignment or transfer, the Bank shall have no
          further liability hereunder.

XII.      RESTRICTIONS ON FUNDING
          -----------------------

          The Bank shall have no obligation to set aside, earmark, or entrust
          any fund or money with which to pay its obligations under this
          Agreement. The Bank reserves the absolute right at its sole
          discretion to either fund the obligations undertaken by this
          Agreement or to refrain from funding the same and determine the
          extent, nature, and method of such funding.

XIII.     GENERAL ASSETS OF THE BANK
          --------------------------

          The rights of the Executive under this Agreement and of any
          beneficiary of the Executive shall be solely those of an unsecured
          creditor of the Bank. If the Bank shall acquire an insurance policy
          or any other asset in connection with the liabilities assumed by it
          hereunder, it is expressly understood and agreed that neither the
          Executive nor any beneficiary of the Executive shall have any right
          with respect to, or claim against, such policy or other asset. Such
          policy or asset shall not be deemed to be held under any trust for
          the benefit of the Executive or his beneficiaries or to be held in
          any way as collateral security for the fulfilling of the obligations
          of the Bank under this Agreement. It shall be, and remain, a general,
          unpledged, unrestricted asset of the Bank and the Executive or any of
          his beneficiaries shall not have a greater claim to the insurance
          policy or other assets, or any interest in either of them, than any
          other general creditor of the Bank.

XIV.      REORGANIZATION
          --------------

          The Bank will not merge or consolidate with any other company or
          organization, or permit its business activities to be taken over by
          any other organization, unless the new entity expressly acknowledges
          its obligations under this Agreement and abide by its terms.

XX.       CLAIMS PROCEDURE AND ARBITRATION
          --------------------------------

          A.       Named Fiduciary and Plan Administrator
                   --------------------------------------

                   The "Named Fiduciary and Plan Administrator" of this plan
                   shall be David Bruce Knox until his resignation or removal
                   by the Board of Directors. As Named Fiduciary for the
                   management, control and administration of the Executive
                   Salary Continuation Agreement as established herein, he may
                   delegate to others certain aspects of the management and
                   operation responsibilities of the plan including the
                   employment of advisors and the delegation of ministerial
                   duties to qualified individuals.

          B.       In the event a dispute arises over benefits under this Plan
                   Agreement and benefits are not paid to the Executive (or to
                   his beneficiary(ies) in the case of the Executive's death)
                   and such claimants feel they are entitled to receive such
                   benefits, then a written claim must be made to the Fiduciary
                   and Administrator named above within sixty (60) days from
                   the date payments are refused. The Plan Fiduciary and
                   Administrator and the Bank shall review the written claim
                   and if the claim is denied,



                                       5


<PAGE>   6



                   in whole or in part, they shall provide in writing within
                   ninety (90) days of receipt of such claim their specific
                   reasons for such denial, reference to the provisions of this
                   Agreement upon which the denial is based and any additional
                   material or information necessary to perfect the claim. Such
                   written notice shall further indicate the additional steps
                   to be taken by claimants if a further review of the claim
                   denial is desired. A claim shall be deemed denied if the
                   Plan Fiduciary and Administrator fails to take any action
                   within the aforesaid ninety-day period.

                   If claimants desire a second review, they shall notify the
                   Plan Fiduciary and Administrator in writing within sixty
                   (60) days of the first claim denial. Claimants may review
                   the Plan Agreement or any documents relating thereto and
                   submit any written issues and comments they may feel
                   appropriate. In its sole discretion, the Plan Fiduciary and
                   Administrator shall then review the second claim and provide
                   a written decision within sixty (60) days of receipt of such
                   claim. This decision shall likewise state the specific
                   reasons for the decision and shall include reference to
                   specific provisions of the Plan Agreement upon which the
                   decision is based.

                   If claimants continue to dispute the benefit denial based
                   upon completed performance of the Agreement or the meaning
                   and effect of the terms and conditions thereof, then
                   claimants may submit the dispute to a Board of Arbitration
                   for final arbitration. Said Board shall consist of one
                   member selected by the Bank, one member selected by
                   claimant, and the third member selected by the first two
                   members. The Board shall operate under any generally
                   recognized set of arbitration rules. The parties hereto
                   agree that they and their heirs, personal representatives,
                   successors and assigns shall be bound by the decision of
                   such Board with respect to any controversy properly
                   submitted to it for determination.

                   Where a dispute arises as to the Bank's discharge of the
                   Executive "for cause", such dispute shall likewise be
                   submitted to arbitration as above described and the parties
                   hereto agree to be bound by the decision thereunder.

          In witness whereof, the Bank has caused this Agreement to be signed
in its corporate name by its duly authorized officers, and the Executive
hereunto set his hand, all on the day and year first above written.

            AMENDMENT TO THE EXECUTIVE SALARY CONTINUATION AGREEMENT
                             DATED DECEMBER 7, 1994
                 BETWEEN UNITY SAVINGS BANK AND GEORGE L. KNOX

EXCERPT FROM SEPTEMBER 18, 1995 BOARD OF DIRECTORS MEETING OF UNITY SAVINGS
BANK:

It was moved by Emmett Conway, Jr. and seconded by G. Richard Brown that the
following amendments be made to the EXECUTIVE SALARY CONTINUATION AGREEMENT
dated December 7, 1994 between Unity Savings Bank and George L. Knox:

V.       DEATH BENEFIT PRIOR TO RETIREMENT
         ---------------------------------

         In the event the Executive should while actively employed by the Bank
at any time after the date of this Agreement but prior to this attaining the age
of seventy (70) years (or such later date as may be agreed upon), the Bank will
pay a benefit equal to the balance in the accrued liability retirement account
in a lump sum to such individual or individuals as the Executive may have
designated in writing and filed with the Bank. In the absence of any effective
designation of beneficiary any such amount becoming due and payable upon the
death of the Executive shall be payable to the duly qualified executor or
administrator of his estate provided, however that anything hereinabove to the
contrary notwithstanding, no death benefit shall be payable hereunder if it is
determined that the Executive's death was caused by suicide on or before
June 9, 1996.

VI.      BENEFIT ACCOUNTING
         ------------------

         The Bank shall account for this benefit using the regulatory accounting
principles of the Bank's primary federal regulator. The Bank shall establish an
accrued liability retirement account for the Executive into which appropriate
reserves shall be accrued in the amount determined by the Bank's certified
public accounting firm.

VII.     VESTING
         -------

         The Executive's interest in the benefits shall not vest until the
Retirement Date (Paragraph III). On the Retirement Date, the Executive shall
become one hundred percent (100%) vested in the benefits under this Agreement.

VIII.    OTHER TERMINATION OF EMPLOYMENT
         -------------------------------

         In the event that the employment of the Executive shall terminate prior
to retirement from active employment, as provided in Paragraph III, by his
voluntary action, or by his discharge by the Bank, the Bank shall pay to the
Executive as severance compensation an amount of money equal to the accrued
balance of the Executive's liability reserve account. This severance
compensation shall be paid in one hundred eighty (180) equal monthly
installments with interest equal to the one year treasury bill as the date of
termination.


<PAGE>   2


         In the event the Executive's death should occur after such severance
but prior to the completion of the monthly payment provided for in the Paragraph
VIII, the remaining installments shall be paid to such individual or individuals
as the Executive may have designated in writing, and filed with the Bank. In the
absence of any effective designation of beneficiary any such amounts shall be
payable to the duly qualified executor or administrator of his estate.

         VOTE:  Adelmann-yes, Brown-yes, Conway-yes, Cotner-yes, D. Bruce
Knox-yes, George L.  Knox-abstained, Simmons-yes."

         I acknowledge and accept this amendment to the Executive Salary
Continuation Agreement originally adopted by the Board of Unity Savings Bank on
December 7, 1994.
