                            STEUBENVILLE, OHIO 43592


                              ______________, 1997




To Our Shareholders:

         A special meeting (the "Special Meeting") of shareholders of UniBank
has been scheduled for ____________, 1998 at 2:00 p.m. in UniBank's main office
located in the Sinclair Building (lower level) at 100 North Fourth Street,
Steubenville, Ohio. The accompanying Notice of the Special Meeting, Proxy
Statement/Prospectus and Proxy Card set forth the formal business to be
transacted at the Special Meeting. I encourage you to review these materials and
to attend the Special Meeting.

         At the Special Meeting, holders of UniBank common shares, par value
$10.00 per share, are being asked to consider and vote upon a proposal (the
"Proposal") to adopt the Affiliation Agreement and Agreement of Merger (the
"Affiliation Agreement"), dated as of September 12, 1997 by and among UniBank,
Citizens Bancshares, Inc. ("Bancshares") and The Citizens Banking Company
("Citizens"), providing for the affiliation and merger (the "Merger") of UniBank
with and into Citizens, and to approve the transactions contemplated thereby. In
the Merger, each outstanding common share of UniBank will be converted into the
right to receive common shares, without par value, of Bancshares in accordance
with the exchange ratio set forth in the Affiliation Agreement and described in
the accompanying Proxy Statement/Prospectus (with cash paid in lieu of
fractional shares).

         Consummation of the Merger is subject to certain conditions, including,
but not limited to, obtaining the requisite vote of the shareholders of UniBank
and the approval of the Merger by various regulatory agencies.

         THE UNIBANK BOARD OF DIRECTORS HAS UNANIMOUSLY CONCLUDED THAT THE
MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE UNIBANK SHAREHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL. UniBank's financial
advisor, Danielson Associates, Inc., has rendered an opinion dated September 12,
1997, and updated to the date hereof, to the UniBank Board of Directors to the
effect that, as of the date hereof and based upon and subject to certain matters
stated in such opinion, the Merger contemplated by the Affiliation Agreement is
fair to the shareholders of UniBank from a financial point of view.

         If the accompanying Proxy Card is executed properly and returned to
UniBank in time to be voted at the Special Meeting, the shares represented
thereby will be voted in accordance with the instructions marked thereon.
Executed but unmarked proxies will be voted for approval of the Proposal. The
presence of a shareholder at the Special Meeting will not automatically revoke
such shareholder's proxy. A UniBank shareholder may, however, revoke a proxy at
any time prior to its exercise by filing a written notice of revocation with or
delivering a duly executed proxy bearing a later date to William W. McElwain,
UniBank, 100 North Fourth Street, Steubenville, Ohio 43592-5640 or by attending
the Special Meeting and advising the Secretary of the shareholder's intent to
vote the shares.

         Approval of the Proposal requires the affirmative vote of the holders
of 60% of the outstanding common shares of UniBank. Accordingly, it is very
important that your shares be represented at the Special Meeting. I urge you to
vote FOR the Proposal and to sign, date and return the accompanying Proxy Card
as soon as possible, even if you plan to attend the Special Meeting. This
procedure will


<PAGE>   5



not prevent you from voting in person, but will ensure that your vote is counted
if you are unable to attend.

                                   Very truly yours,



                                   H. Lee Kinney
                                   Chairman and Chief Executive Officer


                             YOUR VOTE IS IMPORTANT

 WE ENCOURAGE YOU TO SIGN, DATE AND PROMPTLY RETURN YOUR PROXY IN THE ENCLOSED
     ENVELOPE REGARDLESS OF WHETHER YOU PLAN TO ATTEND THE SPECIAL MEETING.

                                     SUMMARY
                                     -------

         This summary is necessarily general and abbreviated and has been

of the matters covered in the Proxy Statement/Prospectus and is qualified in all

Statement/Prospectus and the Appendices hereto, which UniBank shareholders are
urged to read carefully.

THE PARTIES

Citizens Bancshares, Inc.               Bancshares is a bank holding company
                                   organized under the laws of the State of Ohio
                                   and registered with the Board of Governors of
                                   the Federal Reserve System (the "Federal
                                   Reserve Board") pursuant to the Bank Holding
                                   Company Act of 1956, as amended. Bancshares
                                   is a holding company for Citizens, a
                                   wholly-owned commercial bank subsidiary
                                   organized and existing under the banking laws
                                   of the State of Ohio; First National Bank of
                                   Chester, a wholly owned commercial bank
                                   subsidiary organized under the laws of the
                                   United States, ("FNB"); Freedom Express,
                                   Inc., a wholly owned courier company; and
                                   Freedom Financial Life Insurance Company, a
                                   wholly owned reinsurance company. As of
                                   September 30, 1997 and December 31, 1996,
                                   Bancshares had total consolidated assets of
                                   approximately $1 billion and $947.9 million
                                   and total shareholders' equity of
                                   approximately $99.9 million and $89.7
                                   million, respectively.

                                        A part of Bancshares' long term strategy
                                   is to be an active acquiror of financial
                                   institutions so as to leverage its operations
                                   and position itself to enhance shareholder
                                   value. Since 1984, Bancshares has made twelve
                                   acquisitions totaling $647 million in assets.
                                   Bancshares' stock price has increased 3,025%
                                   from 1984 to December 2, 1997. Since June of
                                   1993, Bancshares' Common Shares have been
                                   traded on the NASDAQ National Market. Prior
                                   to June, 1993, Bancshares' stock was traded
                                   over the counter. For the nine months ended
                                   September 30, 1997, Bancshares' annualized
                                   return on assets and return on equity was
                                   1.70% and 18.3%, respectively.

                                        On December 3, 1997, Century Financial
                                   Corporation ("Century"), of Rochester,
                                   Pennsylvania, and Bancshares executed a
                                   definitive Agreement and Plan of Merger (the
                                   "Century Agreement"), which provides for the
                                   affiliation of Century with Bancshares. The
                                   Century Agreement provides that the
                                   affiliation will be effected by means of a
                                   merger of Century with and into Bancshares.
                                   In the merger, each outstanding share of
                                   Century common stock, par value $0.835 per
                                   share, will be converted into 0.425 shares of
                                   Bancshares common shares, in a tax-free
                                   exchange, subject to certain adjustments
                                   based on the then current closing price of
                                   Bancshares common shares on the NASDAQ
                                   National Market System. See "Management's

                                   number of outstanding shares of UniBank

PROPOSED MERGER

The Affiliation Agreement               Bancshares and UniBank have entered into
                                   an Affiliation Agreement, pursuant to which
                                   Bancshares and UniBank will affiliate with
                                   one another through a merger of UniBank with
                                   and into Citizens. Consummation of the
                                   Merger, however, is subject to the approval
                                   of the UniBank shareholders of the
                                   Affiliation Agreement and the transactions
                                   contemplated thereby (including the Merger).
                                   The Merger is expected to qualify as a
                                   "pooling of interests" for accounting and
                                   financial reporting purposes.

                                        For a complete description of the
                                   Affiliation Agreement, which is incorporated
                                   by reference herein in its entirety, see
                                   "Proposed Merger."

Consideration for UniBank
Common Shares                           Upon consummation of the Merger, each
                                   UniBank shareholder who does not exercise his
                                   or her right to become a dissenting
                                   shareholder will have the right to receive
                                   13.25 Bancshares Common Shares in exchange
                                   for each UniBank Common Share held. In the
                                   event, however, that the holders of UniBank
                                   Common Shares, in the aggregate, do not
                                   receive Bancshares Common Shares with a total
                                   value (as that term is defined in the
                                   Affiliation Agreement), plus cash in lieu of
                                   fractional shares, that is at least 2.7
                                   times the book value of UniBank Common Shares
                                   on December 31, 1997, the parties will adjust
                                   the number of Bancshares Common Shares into
                                   which each UniBank Common Share shall be
                                   converted, although Bancshares may elect to
                                   terminate the Affiliation Agreement if the
                                   book value of UniBank Common Shares exceeds
                                   $250 per share.

                                        For a complete description of the
                                   consideration to be received by UniBank
                                   shareholders, see "PROPOSED MERGER--
                                   Consideration for UniBank Common Shares."

UniBank Background
and Reasons for the Merger              UniBank entered into the Affiliation
                                   Agreement to further strengthen two very
                                   sound community banks, thereby providing
                                   greater advancement opportunity for its
                                   employees, a wider range of financial
                                   services for its customers, larger lending
                                   limits for individuals, businesses and
                                   industries in its trade area, and optimum
                                   economic advantage for its stockholders.

Bancshares Background
and Reasons for the Merger              Bancshares' Board of Directors has
                                   concluded that the Merger would be in the
                                   best interest of Bancshares' shareholders and
                                   the depositors, other customers and


                                      -4-
<PAGE>   18




                                   employees of its subsidiary banks. The Merger
                                   is consistent with Bancshares' overall
                                   strategic acquisition program and, in
                                   particular, its interest in expanding
                                   Citizens' facilities and services in
                                   Jefferson County, Ohio. Bancshares' and
                                   Citizens' philosophies of emphasizing
                                   customer service and satisfaction, promoting
                                   local and branch level decision-making power
                                   by employees and making strong, ongoing
                                   commitments to each community they serve are
                                   consistent with UniBank's management
                                   philosophies and its long-standing reputation
                                   of service to Jefferson County. In addition,
                                   the current products and services offered by
                                   UniBank are similar to, and in many respects
                                   complements, the products and services
                                   provided by Citizens. Bancshares anticipates
                                   that the additional products and services of
                                   Citizens that will become available to
                                   UniBank customers as a result of the Merger
                                   will provide opportunities for expanded and
                                   new customer relationships. Bancshares also
                                   believes that the Merger can be accomplished
                                   with little or no resulting dilution in the
                                   value of Bancshares Common Shares. See
                                   "PROPOSED MERGER -- Bancshares' Background
                                   and Reasons for the Merger."

                                   an original opinion to UniBank's Board of

                                   are urged to read such opinion in its
                                   entirety for a description of the procedures

                                   therewith.

                                   time employees of UniBank the opportunity to
                                   become full time employees of Citizens or one
                                   of Bancshares' other affiliates for a minimum
                                   period of six months. In addition, Bancshares
                                   will offer the existing part time employees
                                   of UniBank the opportunity to become part
                                   time employees of Citizens or one of
                                   Bancshares other affiliates for minimum
                                   period of six months; provided, however, that
                                   Bancshares may determine in its sole
                                   discretion the number of hours that the part
                                   time employee will be scheduled to work. See
                                   "PROPOSED MERGER--Operations of UniBank After

Recommendation of the
Board of Directors                      The UniBank Board of Directors has
                                   unanimously approved the Affiliation
                                   Agreement and believes that the Affiliation
                                   Agreement is fair to and in the best
                                   interests of UniBank shareholders. The

Federal Income Tax
Consequences of the
Merger                                  It is intended that the Merger will be
                                   treated as a reorganization within the
                                   meaning of Section 368(a) of the Internal
                                   Revenue Code of 1986, as amended, and that,
                                   accordingly, for federal income tax purposes
                                   no gain or loss will be recognized by
                                   UniBank, Bancshares or Citizens as a result
                                   of the Merger. The obligations of UniBank to
                                   consummate the Merger are conditioned upon
                                   the receipt by it of a letter from Rick Hull,
                                   Esq., Bancshares' general counsel, advising
                                   that based on his review of the Affiliation
                                   Agreement nothing has come to his attention
                                   that would lead him to believe that the
                                   Merger will not be tax free with respect to
                                   the holders of UniBank Common Shares.
                                   Shareholders who exercise dissenters' rights
                                   and receive cash for their UniBank Common
                                   Shares will be treated as having received a
                                   distribution in redemption of their shares
                                   which will result in such shareholders
                                   receiving income for federal income tax
                                   purposes.

                                        All UniBank shareholders should read
                                   carefully the description under "PROPOSED
                                   MERGER--Federal Income Tax Consequences of
                                   the Merger," and should consult their own tax
                                   advisors concerning these matters.

Conditions; Amendments;
Termination                             Completion of the Merger is contingent
                                   upon approval of the Affiliation Agreement by
                                   UniBank shareholders and certain regulatory
                                   authorities and upon certain other conditions
                                   described in this Proxy Statement/
                                   Prospectus. The Affiliation Agreement may not
                                   be amended except by a written agreement
                                   executed by the party to be charged with the
                                   amendment.

                                        The Affiliation Agreement may be
                                   terminated as follows: (i) by either
                                   Bancshares or UniBank as a result of a

                                   (ii) by Bancshares or UniBank if the
                                   conditions precedent to their respective
                                   obligations to consummate the Merger have not
                                   been satisfied or waived by the appropriate
                                   party; (iii) by mutual consent of Bancshares
                                   and UniBank; or (iv) by UniBank if the
                                   average NMS closing price of Bancshares
                                   Common Shares is 20% or more lower than the
                                   average National Market System closing price
                                   of those banks set forth in Exhibit 9.1 to
                                   the Affiliation Agreement; (iv) by Bancshares
                                   if the average NMS closing price of
                                   Bancshares Common Shares is less than $46.00;
                                   or (v) by Bancshares in the event that the
                                   number of Bancshares Common Shares into which
                                   each UniBank Common Share is to be converted
                                   will be adjusted pursuant to Section 1.2(a)
                                   of the Affiliation Agreement and the book
                                   value of UniBank Common Shares exceeds $250
                                   per share; or (vi) by Bancshares or UniBank
                                   if the Merger has not occurred by June 30,
                                   1998.

                                   of the Affiliation Agreement."

Management after the
Merger                                  Upon completion of the Merger, it is
                                   anticipated that the directors and executive
                                   officers of Bancshares and Citizens will
                                   remain directors and executive officers
                                   thereof. In addition, one member of UniBank's
                                   Board of Directors, namely H. Lee Kinney,
                                   shall have the right to serve on the Board of
                                   Directors of both Bancshares and Citizens,
                                   each for a one year term. See "PROPOSED
                                   MERGER--Operations of UniBank After the
                                   Merger."


COMPARATIVE RIGHTS OF
UNIBANK
SHAREHOLDERS                            The rights of shareholders of Bancshares
                                   and shareholders of UniBank, while similar in
                                   many respects, also differ in some respects.
                                   For a description of the relative rights of
                                   the holders of Bancshares Common Shares and
                                   UniBank Common Shares, see "COMPARATIVE
                                   RIGHTS OF UNIBANK SHAREHOLDERS." Bancshares'
                                   Articles of Incorporation include a provision
                                   governing the acquisition of certain
                                   controlling interests in Bancshares. For a
                                   description of this provision, see

                                  RISK FACTORS
                                  ------------

         IN ADDITION TO THE OTHER INFORMATION CONCERNING BANCSHARES AND ITS
SUBSIDIARY BANKS IN THIS JOINT PROXY STATEMENT/PROSPECTUS, THE FOLLOWING RISK
FACTORS SHOULD BE CONSIDERED CAREFULLY.

Impact of Government Monetary Policies
- --------------------------------------

         The earnings of banks and bank holding companies such as Bancshares are
affected by the policies of regulatory authorities, including the Federal
Reserve Board, which regulates the money supply. Among the methods employed by
the Federal Reserve Board 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 methods are used in
varying combinations to influence overall growth and distribution of bank loans,
investments and deposits, and their use may also affect interest rates charged
on loans or paid on deposits. The monetary policies of the Federal Reserve Board
have had a significant effect on the operating results of commercial and savings
banks in the past and are expected to continue to do so in the future.

Allowance for Loan Losses
- -------------------------

         Bancshares' allowance for loan losses is maintained at a level
considered adequate by management to absorb anticipated losses. The amount of
future losses is susceptible to changes in economic, operating and other
conditions, including changes in interest rates, that may be beyond Bancshares'
control and such losses may exceed current estimates. At September 30, 1997,
Bancshares had total nonperforming loans of approximately $3,078,000. At the
same date, Bancshares' allowance for loan losses was $11,961,000, or 1.91% of
total loans 389% of total nonperforming loans. There can be no assurance,
however, that such allowance will be adequate to cover actual losses.

Competitive Banking Environment
- -------------------------------

         Intense competition exists in all aspects of business in which
Bancshares is presently engaged, not only with other commercial banks and trust
companies but also with thrifts, finance companies, personal loan companies,
credit unions, leasing companies, money market mutual funds, investment firms,
mortgage bankers, and other financial institutions serving Bancshares' market
area.

         Financial institutions compete on the basis of price, including
interest rates paid on deposits and charged on loans, convenience and quality of
service. This competition includes banks which are many times larger than
Bancshares' banking subsidiaries. Bancshares is encountering increased
competition from non-bank financial institutions. Thrift institutions, credit
unions and small loan companies each are significant factors in the traditional
lending and deposit gathering business of Bancshares. Insurance companies,
investment firms and retailers all are significant competitors for various types
of business. Many of Bancshares' competitors are larger and have greater
resources than Bancshares, and there are no assurances that Bancshares will be
able to compete effectively against such companies in the future.

Government Regulation
- ---------------------

         Bancshares and its banking subsidiaries are subject to extensive
governmental supervision, regulations and control. Future legislation and
government policy could adversely affect the banking industry and the operations
of Bancshares. There can be no assurance that the profitability of Bancshares
will not be adversely affected by changes in applicable laws, regulations and
policies.

Ability to Integrate Operations and Achieve Cost Savings After the Merger
- -------------------------------------------------------------------------

         The earnings and financial condition of Bancshares after the Merger
will depend in part on its ability to successfully integrate the operations and
management of UniBank with and into The Citizens Banking Company. There can be
no assurance that Bancshares will be able to effectively and profitably
integrate the operations and management of UniBank. Further, although Bancshares
anticipates cost savings as a result of the Merger, there can be no assurance
that it will be able to fully realize any of the potential cost savings expected
as a result of Bancshares and UniBank being able to share administrative and
other resources when their operations are integrated. Finally, there can be no
assurance that any cost savings which are realized will not be offset by
decreases in revenues or other charges to earnings.


 PRO FORMA SELECTED FINANCIAL INFORMATION
- ----------------------------------------

         The table below sets forth selected pro forma financial information for
Bancshares and UniBank combined as of and for the nine months ended September
30, 1997 and 1996, and as of and for the years ended December 31, 1996, 1995 and
1994. This information is derived from and should be read in conjunction with
the historical financial statements of Bancshares and UniBank that are
incorporated by reference or appear elsewhere in this Proxy
Statement/Prospectus, and with the pro forma condensed consolidated financial
statements of Bancshares, which give effect to the Merger and which appear in
this Proxy Statement/Prospectus under the caption "PRO FORMA FINANCIAL
INFORMATION." The pro forma condensed consolidated financial information has
been prepared based on the use of "pooling of interests" method of accounting
assuming that 945,056 Bancshares Common Shares will be issued and that no
UniBank shareholders will dissent. The number of Bancshares Common Shares issued
assumes an exchange ratio such that one UniBank Common Share will be exchanged
for 13.25 Bancshares Common Shares. This information will vary if any UniBank
shareholders dissent or if the total value of Bancshares Common Shares to be
issued for a UniBank Common Share plus cash in lieu of fractional shares is less
than 2.7 times the book value of a UniBank Common Share at December 31, 1997.
The historical financial information of Bancshares and UniBank has been combined
for each period presented. For a discussion of the pooling of interests method
of accounting and the condition to Bancshares' and UniBank's obligations under
the Affiliation Agreement that the Merger qualify for the pooling of interests
method of accounting, see "PROPOSED MERGER--Accounting Treatment" and "Other
Provisions of the Affiliation Agreement."

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

         The following table sets forth Bancshares' and UniBank's historical per
share data and pro forma combined per share data. The information is based on
the historical financial statements of Bancshares and UniBank. The pro forma
data do not purport to be indicative of the results of future operations or the
actual results that would have occurred had the Merger been consummated at the
beginning of the periods presented. The pro forma data give effect to the Merger
and are based on numerous assumptions and estimates. The pro forma data are
included as required by the rules of the Commission and are provided for
comparative purposes only. The pro forma combined per share data and UniBank
equivalent per share data are prepared assuming 945,056 Bancshares Common Shares
will be issued based on an exchange ratio such that one UniBank Common Share
will be exchanged for 13.25 Bancshares Common Shares. This information will vary
if any UniBank Shareholders dissent or if the total value of Bancshares Common
Shares to be issued for a UniBank Common Share plus cash in lieu of fractional
shares is less than 2.7 times the book value of a UniBank Common Share at
December 31, 1997.

         Bancshares Common Shares began trading on the NASDAQ National Market
under the symbol "CICS" as of June 1, 1993. The information presented in the
following table reflects the last reported sale price for Bancshares on 
September 11, 1997, the last trading day preceding execution of the Affiliation
Agreement. No assurance can be given as to what the market price of Bancshares 
Common Shares will be if and when the Merger is consummated. 

         There is no public trading market for UniBank Common Shares and there
is no published information with respect to its market price. The equivalent per
share basis has been circulated by multiplying the last reported sale price of
Bancshares Common Shares on September 11, 1997, by the exchange ratio, assuming
a 13.25 exchange ratio (which exchange ratio would be applicable if Bancshares
Common Shares has an average closing price of $53.00). See also "INFORMATION
WITH RESPECT TO BANCSHARES--Market Price of Bancshares Common Shares" and

                   INFORMATION CONCERNING THE SPECIAL MEETING
                   ------------------------------------------

General
- -------

         This Proxy Statement/Prospectus is being furnished to holders of
UniBank Common Shares as part of the solicitation of proxies by the UniBank
Board of Directors for use at the Special Meeting to be held on ____________,
1998 at 2:00 p.m. in UniBank's main office located in the Sinclair Building
(lower level) at 100 North Fourth Street, Steubenville, Ohio, including any
adjournments or reschedulings thereof. This Proxy Statement/Prospectus and the
accompanying Proxy Card are first being mailed to shareholders of UniBank on or
about __________, 1997.

         The purpose of the Special Meeting is to consider and vote upon the
Proposal to adopt the Affiliation Agreement and to approve the transactions
contemplated thereby, including the Merger. No other business will be transacted
at the Special Meeting other than possible adjournments or reschedulings
thereof.

         The Merger is subject to a number of conditions, including the receipt
of required regulatory and shareholder approvals. (See "PROPOSED
MERGER--"Regulatory Approvals" and "Other Provisions of the Affiliation
Agreement.")

Solicitation, Voting and Revocability of Proxies
- ------------------------------------------------

         The UniBank Board has fixed the close of business on ______________,
1997 (the "Record Date") as the record date for the determination of the
shareholders of UniBank entitled to notice of and to vote at the Special
Meeting. Only holders of record of UniBank Common Shares at the close of
business on the Record Date will be entitled to vote on each matter properly
presented at the Special Meeting. On the Record Date, 75,000 UniBank Common
Shares were issued and outstanding. Votes may be cast in person or by proxy, and
each UniBank Common Share entitles its holder to one vote. Pursuant to the
UniBank Code of Regulations and in accordance with the Ohio Revised Code
("ORC"), the presence of the holders of a majority of the UniBank Common Shares
issued and outstanding, in person or by proxy, and entitled to vote at the
Special Meeting is required for and shall constitute a quorum for the
transaction of business at the Special Meeting. For such purpose, abstentions
and broker non-votes will be counted in establishing the quorum. A majority of
the UniBank Common Shares present at the Special Meeting, in person or by proxy,
whether or not constituting a quorum, may vote to, or the UniBank Board in its
discretion may, adjourn the Special Meeting from time to time without further
notice, including for the purpose of soliciting additional proxies. Pursuant to
the UniBank Code

                                      -10-
<PAGE>   24



of Regulations, the affirmative vote of the holders of at least 60% of the total
number of outstanding UniBank Common Shares entitled to vote at the Special
Meeting is required to approve the Proposal. An abstention and a broker non-vote
would thus have the same effect as a vote against the Proposal.


         Only shareholders of record on the Record Date are eligible to give
their proxies. Therefore, shareholders owning shares held in the name of a
brokerage firm, bank, or other institution should sign, date and return their
proxy cards to such brokerage firm, bank or other institution in the envelope
provided by that firm. In addition, brokers who hold shares in street name for
customers who are the beneficial owners of such shares are prohibited from
giving a proxy to vote shares held for such customers on the approval of the
Proposal without specific instructions from such customers. Given that the
UniBank Code of Regulations requires the affirmative vote of the holders of 60%
of the outstanding UniBank Common Shares entitled to vote at the Special Meeting
in order to approve the Proposal, the failure of such customers to provide
specific instructions with respect to their UniBank Common Shares to their
broker will have the effect of a vote against the approval of the Proposal.
Failure to return a properly executed proxy card or to vote at the Special
Meeting will have the same effect as a vote against the Proposal.

         Proxies in the accompanying form which are properly executed and
returned to UniBank will be voted at the Special Meeting in accordance with the
shareholders' instructions contained in such proxies and, at the discretion of
the Proxy Committee, on such other matters as may properly come before the
meeting. If a shareholder returns a proxy card that is signed, dated and not
marked, that shareholder will be deemed to have voted for the Proposal. An
executed proxy may be revoked at any time prior to its exercise by submitting
another proxy with a later date, by appearing in person at the Special Meeting
and advising the Secretary of the shareholder's intent to vote the shares or by
sending a written, signed and dated revocation which clearly identifies the
proxy being revoked to the principal executive offices of UniBank at 100 North
Fourth Street, Steubenville, Ohio 43592-5640. A revocation may be in any written
form validly signed by the record holder as long as it clearly states that the
proxy previously given is no longer effective. In addition, shareholders whose
UniBank Common Shares are not registered in their own name will need additional
documentation from the record holder of such shares to vote in person at the
Special Meeting.

         Proxies may be solicited by mail, telephone, telegraph, telex,
telecopier and advertisement and in person. Solicitation may be made in the same
manner by directors, officers and other representatives of UniBank who will not
be specially compensated for such activities, but who may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation.

         Banks, brokerage houses and other custodians, nominees and fiduciaries
will be requested to forward the solicitation materials to the beneficial owners
of UniBank Common Shares for which they hold of record, and UniBank will
reimburse them for their reasonable out-of-pocket expenses.

         The expenses related to the proxy solicitation for the Special Meeting
will be borne by UniBank, except that the cost of preparing and mailing this
Proxy Statement/Prospectus will be borne by UniBank and Bancshares.

         The directors and executive officers of UniBank and their affiliates
owned, as of the Record Date, 44,176 UniBank Common Shares (58.89% of the total
number of outstanding shares of UniBank Common Shares at such date).

                                 PROPOSED MERGER
                                 ---------------

         The following description of certain aspects of the Merger does not
purport to be complete and is qualified in its entirety by reference to the
Affiliation Agreement which is set forth in Appendix A, attached to and
incorporated by reference in this Proxy Statement/Prospectus. All shareholders
are urged to read the Affiliation Agreement in its entirety.

UniBank Background and Reasons for the Merger
- ---------------------------------------------

         UniBank entered into the Affiliation Agreement to further strengthen
two very sound community banks, thereby providing greater advancement
opportunity for its employees, a wider range of financial services for its
customers, larger lending limits for individuals, businesses and industries in
its trade area, and optimum economic advantage for its stockholders.

Recommendation of the UniBank Board of Directors
- ------------------------------------------------

         IN VIEW OF ALL THE CONSIDERATIONS DESCRIBED ABOVE, THE BOARD OF
DIRECTORS OF UNIBANK UNANIMOUSLY CONCLUDED THE MERGER IS IN THE BEST INTERESTS
OF AND IS FAIR TO THE UNIBANK SHAREHOLDERS AND RECOMMENDS THAT UNIBANK
SHAREHOLDERS VOTE FOR THE MERGER.

Opinion of UniBank's Financial Advisor
- --------------------------------------

         UniBank retained Danielson Associates, Inc. ("Danielson Associates") to
advise the UniBank Board of Directors as to its "fair" sale value and the
fairness to its shareholders of the financial terms of the offer to acquire
UniBank. Danielson Associates is regularly engaged in the valuation of banks,
bank holding companies, and thrifts in the connection with mergers,
acquisitions, and other securities transactions; and has knowledge of, and
experience with, the Ohio banking markets and banking organizations operating in
those markets. Danielson Associates was selected by UniBank because of its
knowledge of, expertise with, and reputation in the financial services industry.

         In such capacity, Danielson Associates reviewed the Merger Agreement
with respect to the pricing and other terms and conditions of the Merger, but
the decision as to accepting the offer was ultimately made by the Board of
Directors of UniBank. Danielson Associates rendered its oral opinion to the
UniBank Board of Directors, and subsequently confirmed in writing, that as
of the date of such opinion, the financial terms of the Citizens offer were
"fair" to UniBank and its shareholders. No limitations were imposed by the
UniBank Board of Directors upon Danielson Associates with respect to the
investigation made or procedures followed by it in arriving at its opinion.

         In arriving at its opinion, Danielson Associates (a) reviewed certain
business and financial information relating to UniBank and Citizens, including
annual reports for the fiscal year ended December 31, 1996 and call report data
from 1989 to 1996 including quarterly reports for 1997; (b) discussed the past
and current operations, financial condition and prospects of UniBank with its
senior executives; (c) analyzed the pro forma impact of the merger on Citizens'
earnings per share, capitalization, and financial ratios; (d) reviewed the
reported prices and trading activity for the UniBank and the Citizens Common
Stock and compared them to similar bank holding companies; (e) reviewed and
compared the financial terms, to the extent publicly available, with comparable
transactions; (f)



                                      -12-
<PAGE>   26



reviewed the Merger Agreement and certain related documents; and (g) considered
such other factors as were deemed appropriate.

         Danielson Associates did not obtain any independent appraisal of assets
or liabilities of UniBank or Citizens or their respective subsidiaries. Further,
Danielson Associates did not independently verify the information provided by
UniBank or Citizens and assumed the accuracy and completeness of all such
information.

         In arriving at its opinion, Danielson Associates performed a variety of
financial analyses. Danielson Associates believes that its analyses must be
considered as a whole and that consideration of portions of such analyses and
the factors considered therein, without considering all the factors and
analyses, could create an incomplete view of the analyses and the process
underlying Danielson Associates' opinion. The preparation of a fairness opinion
is a complex process involving subjective judgements and is not necessarily
susceptible to partial analysis and summary description.

         In its analyses, Danielson Associates made certain assumptions with
respect to industry performance, business and economic conditions, and other
matters, many of which were beyond UniBank's or Citizens' control. Any estimates
contained in Danielson Associates' analyses are not necessarily indicative of
the future results of value, which may be significantly more or less favorable
than such estimates. Estimates of values of companies do not purport to be
appraisals or necessarily reflect the prices at which companies or their
securities may actually be sold.

         The following is a summary of selected analyses considered by Danielson
Associates in connection with its opinion letter.

Pro Forma Merger Analyses

         Danielson Associates analyzed the changes in the amount of earnings and
book value represented by the receipt of about $52.7 million for all of the
outstanding shares of UniBank Common Stock, which will be paid in Citizens
common stock. The analysis evaluated, among other things, possible dilution in
earnings and capital per share for Citizens Common Stock.

Comparable Companies

         Danielson Associates compared UniBank's (a) tangible capital of 7.05%
of assets as of June 30, 1997, (b) .17% of assets nonperforming as of June 30,
1997, and (c) net operating income of 1.65% of average assets for the trailing
twelve month period ended June 30, 1997, with the medians for selected Ohio
banks which Danielson Associates deemed comparable. These banks included Andover
Bancorp, Belmont Savings Bank, CSB Bancorp, FNB Financial, Killbuck Bancshares,
Mechanics Financial, National Bancshares and United Bancorp. Their medians were
(a) tangible capital of 10.16% of assets, (b) .37% of assets nonperforming, and
(c) net operating income of 2.07% of average assets.

         Danielson Associates also compared Citizens' (a) stock price as of
September 12, 1997 equal to 20.1 times earnings and 330% of book, (b) dividend
yield based on trailing four quarters as of June 30, 1997 and stock price as of
September 12, 1997 of 2.00%, (c) tangible capital as of June 30, 1997 of 8.94%
of assets, (d) nonperforming assets as of June 30, 1997 equal to .41% of total
assets, (e) return on average assets during the trailing four quarters ended
June 30, 1997 of 1.70% and (f) return on average equity during the same period
of 18.18%, with the medians for selected banks and bank holding companies that
Danielson Associates deemed to be comparable to Citizens. The selected
institutions included BancFirst Ohio Corp., City Holding Company, CoBancorp,
Inc., First Financial Bancorp, Horizon Bancorp, Inc., Matewan Bancshares, Inc.,
Mid Am Inc., Park National Corporation, Second Bancorp, Incorporated and United
Bancshares, Inc.. The comparable medians were (a) stock


                                      -13-
<PAGE>   27



price of 18.8 times earnings and 244% of book, (b) dividend yield of 2.57%, (c)
tangible capital of 8.65% of assets, (d) .59% of assets nonperforming, (e)
return on average assets of 1.18% and (f) return on average equity 13.36%.
Danielson Associates also compared other income, expense, and balance sheet
information of such companies with similar information about Citizens.

Comparable Transaction Analysis

         Danielson Associates compared the consideration to be paid in the
merger to the latest twelve months earnings and equity capital of UniBank with
earnings and capital multiples paid in acquisitions of MidAtlantic banks in 1996
and 1997 through the opinion date. Of these, the most applicable recent
transactions included Fulton Financial Corporation buying Keystone Heritage
Group, Inc., Area Bancshares Corporation's purchase of Cardinal Bancshares,
Inc., and a 1996 West Virginia transaction, Horizon Bancorp, Inc. buying
Twentieth Bancorp, Inc.. At the time Danielson Associates made its analysis, the
consideration to be paid in the merger was 296% of UniBank's September 12, 1997
book value and 24.2 times UniBank's earnings for the trailing four quarters as
of June 30, 1997. This compares to the median multiples of 247% of book value
and 20.8 times earnings for the comparable acquisitions.

         The transaction price was also compared to the prices paid for seven
sales involving banks from Kentucky, Maryland, Ohio, Pennsylvania and West
Virginia with assets over $100 million during 1997. The median comparable deal
prices in these transactions were 297% of book and 22.6 times earnings.

Other Analysis

         In addition to performing the analyses summarized above, Danielson
Associates also considered the general market for bank and thrift mergers, the
historical financial performance of UniBank and Citizens, the deposit market
shares of both banks, and the general economic conditions and prospects of those
banks.

         No company or transaction used in this composite analysis is identical
to UniBank or Citizens. Accordingly, an analyses of the results of the foregoing
is not mathematical; rather it involved complex consideration and judgements
concerning differences in financial and operating characteristics of the
companies and other factors that could affect the public trading values of the
company or companies to which they are being compared.

         The summary set forth above does not purport to be a complete
description of the analyses and procedures performed by Danielson Associates in
the course of arriving at its opinions. In payment for its services as the
financial advisor to UniBank, Danielson Associates is to be paid a fee of
$50,000.

         The full text of the opinion of Danielson Associates dated as of
September 12, 1997, and updated to the date hereof, which sets forth assumptions
made and matters considered, is attached hereto as Exhibit C to this Proxy
Statement/Prospectus. UniBank shareholders are urged to read this opinion in its
entirety. Danielson Associates' opinion is directed only to the consideration to
be received by UniBank shareholders in the Merger and does not constitute a
recommendation to any UniBank shareholder as to how such shareholder should vote
at the Shareholders Meeting.

Bancshares Background and Reasons for the Merger
- ------------------------------------------------

         Bancshares' Board of Directors has concluded that the Merger would be
in the best interest of Bancshares' shareholders and the depositors, other
customers and employees of its subsidiary banks. The Merger is consistent with
Bancshares' overall strategic acquisition program and, in particular, its
interest in expanding Citizens' facilities and services in Jefferson County,
Ohio. Bancshares' and


                                      -14-
<PAGE>   28


Citizens' philosophies of emphasizing customer service and satisfaction,
promoting local and branch level decision-making power by employees and making
strong, ongoing commitments to each community they serve are consistent with
UniBank's management philosophies and its long-standing reputation of service to
Jefferson County. In addition, the current products and services offered by
UniBank are similar to, and in many respects, complement the products and
services provided by Citizens. Bancshares anticipates that the additional
products and services of Citizens that will become available to UniBank
customers as a result of the Merger will provide opportunities for expanded and
new customer relationships. Bancshares also believes that the Merger can be
accomplished with little or no resulting dilution in the value of Bancshares
Common Shares.

Description of the Merger
- -------------------------

         Upon consummation of the transactions contemplated under the
Affiliation Agreement, UniBank will be merged with and into Citizens. Citizens
will be the surviving bank after the Merger ("Resulting Bank") and the Articles
of Incorporation and Code of Regulations of Citizens will remain in effect as
they were immediately prior to the Merger. After the Merger, Citizens will
remain a wholly-owned subsidiary of Bancshares. See also "PROPOSED
MERGER--Operations of UniBank After the Merger."

Consideration for UniBank Common Shares
- ---------------------------------------

         Upon consummation of the Merger, each shareholder of UniBank who does
not dissent will have the right to receive 13.25 Bancshares Common Shares for
each of his or her UniBank Common Shares held, plus cash in lieu of the issuance
of fractional shares.

         Notwithstanding the foregoing, in no event, however, will the holders
of UniBank Common Shares receive, in the aggregate, Bancshares Common Shares
with a total value plus cash in lieu of fractional shares that is less than 2.7
times the book value of UniBank Common Shares on December 31, 1997. In such
event, the parties have agreed to adjust the number of Bancshares Common Shares
into which each UniBank Common Share shall be converted; further provided,
however, that in the event the book value of UniBank Common Shares exceeds $250
per share, Bancshares may elect to terminate the Affiliation Agreement.

         The term "Total Value" means the arithmetic mean of the NMS Closing
Prices for the 20 trading days immediately prior to the tenth trading day,
inclusive, immediately prior to the Effective Time. The term "NMS Closing Price"
shall mean the price per share of the last sale of Bancshares Common Shares
reported on the NASDAQ National Market at the close of the trading day by the
National Association of Securities Dealers, Inc.

Payment of Cash in Lieu of Fractional Shares
- --------------------------------------------

         No fractional Bancshares Common Shares will be issued in connection
with the Merger. Each UniBank shareholder who would otherwise have been entitled
to receive a fraction of a Bancshares Common Share will receive, in lieu
thereof, cash therefor, without interest, at a price based upon the NMS Closing
Price.

Other Provisions of the Affiliation Agreement
- ---------------------------------------------

Representations and Warranties

         The Affiliation Agreement contains representations and warranties by
the parties regarding, among other things, their respective organization,
authority to enter into the Affiliation Agreement, capitalization, pending and
threatened litigation, contractual obligations, compliance with applicable


                                      -15-
<PAGE>   29



laws and regulations, financial statements and filings with regulatory agencies.
These representations and warranties will not survive consummation of the
Merger. The Affiliation Agreement includes certain exceptions to UniBank's
representations and warranties, none of which are deemed material to this
transaction. Such exceptions are contained in the Disclosure Schedule to the
Affiliation Agreement which may be reviewed upon request to William W. McElwain
of UniBank, 100 North Fourth Street, Steubenville, Ohio 43592-5640.

Conditions to the Merger

         The obligations of UniBank and Bancshares to consummate the Merger are
subject to, but not limited to the following conditions: (1) the accuracy of
UniBank's and Bancshares' representations and warranties on and as of the
closing date of the Merger; (2) UniBank and Bancshares shall each have performed
or complied with the covenants and conditions that each is required to perform
or comply with under the terms of the Affiliation Agreement; (3) the granting of
all necessary regulatory approvals, including but not limited to the Board of
Governors of the Federal Reserve System, the Ohio Department of Commerce
(Division of Financial Institutions, Office of Banks and Savings & Loans) and
the Securities and Exchange Commission; (4) the issuance by Bancshares' general
counsel and UniBank's counsel of opinions covering certain matters with respect
to Bancshares and UniBank, (5) the consummation nor performance of the
transactions under the Affiliation Agreement will not conflict with, or result
in a material violation of, or cause Bancshares or UniBank or their respective
affiliates to suffer any material adverse consequences under any law or order
applicable to, or proposed to be applicable to them; (6) the registration
statement with the Securities and Exchange Commission registering the exchange
of the Bancshares Common Shares for UniBank Common Shares and all state
securities and "blue sky" permits have become effective and no stop orders or
similar restraining orders shall have been issued; and (7) the receipt by
Bancshares of an opinion letter from Crowe, Chizek and Company LLP stating that
the transaction qualifies for treatment as a "pooling of interests" for
financial statement reporting purposes.

         Bancshares' obligations under the Affiliation Agreement are also
conditioned on, among other conditions, UniBank's shareholders having approved
the Affiliation Agreement and the Merger; the holders of no more than 10% of the
UniBank Common Shares having asserted dissenters' rights; and there having been
no event constituting an event of default under any material indenture,
agreement, note, mortgage or guaranty which materially adversely affects
UniBank's financial condition.

         UniBank's obligations under the Affiliation Agreement are also subject
to, among other conditions, the adoption of the Affiliation Agreement and the
Merger by the requisite vote of UniBank shareholders; the receipt of a letter
from Bancshares' general counsel, Rick Hull, Esq., advising that, based on his
review of the Affiliation Agreement, nothing has come to his attention that
would lead him to believe the exchange of Bancshares Common Shares for UniBank
Common Shares will not be tax free with respect to UniBank shareholders; and the
receipt of a fairness opinion from Danielson Associates, Inc. dated as of the
date of this Proxy Statement/Prospectus stating that the Merger is fair from a
financial point of view to UniBank shareholders.

         The foregoing disclosure regarding conditions to the Merger represents
and includes all material conditions to the consummation thereof.

Amendments; Termination

         The Affiliation Agreement may not be amended except by a written
agreement executed by the party to be charged with the amendment. The
Affiliation Agreement may be terminated as follows: (i) by either Bancshares or
UniBank as a result of a breach of the Affiliation Agreement; (ii) by Bancshares
or UniBank if the conditions precedent to their respective obligations to
consummate the Merger have


                                      -16-
<PAGE>   30



not been satisfied or waived by the appropriate party; (iii) by mutual consent
of Bancshares and UniBank; or (iv) by UniBank if the average NMS closing price
of Bancshares Common Shares is 20% or more lower than the average National
Market System closing price of those banks set forth in Exhibit 9.1 to the
Affiliation Agreement; (iv) by Bancshares if the average NMS closing price of
Bancshares Common Shares is less than $46.00; or (v) by Bancshares in the event
that the number of Bancshares Common Shares into which each UniBank Common Share
is to be converted will be adjusted pursuant to Section 1.2(a) of the
Affiliation Agreement and the book value of UniBank Common Shares on December
31, 1997 exceeds $250 per share; or (vi) by Bancshares or UniBank if the Merger
has not occurred by June 30, 1998.

Federal Income Tax Consequences of the Merger
- ---------------------------------------------

         The Merger is structured to qualify as a tax free reorganization under
Section 368 of the Internal Revenue Code of 1986, as amended, such that it is
anticipated that no gain or loss will be recognized by UniBank, Citizens or
Bancshares as a result of the Merger. Nor is it expected that shareholders of
UniBank will recognize gain or loss upon the exchange of their UniBank Common
Shares for newly issued Bancshares Common Shares, except for cash received in
exchange for fractional interests. Assuming the Merger is treated as a tax-free
reorganization, the federal income tax basis of the Bancshares Common Shares
received by the shareholders of UniBank will be the same as the federal income
tax basis of the UniBank Common Shares surrendered in exchange therefor and the
holding period of the Bancshares Common Shares received by the shareholders of
UniBank will include the holding period of the UniBank Common Shares surrendered
in exchange therefor, provided that the UniBank Common Shares were held as a
capital asset on the date of the exchange.

         Shareholders who exercise their dissenters' rights of appraisal and
receive cash for their UniBank Common Shares will be treated as having received
a distribution in redemption of their shares, which will result in such
shareholders realizing income for federal income tax purposes. Furthermore,
shareholders of UniBank who receive cash in lieu of fractional interests in
Bancshares Common Shares as a result of the exchange will also be treated as
having received a distribution in redemption of their proportionate interest in
UniBank, which will result in such shareholders realizing income for federal
income tax purposes. The amount of such income and the tax treatment thereof
will depend on a number of factual considerations particular to the individual
shareholder.

         The discussion of federal income taxes is included herein for general
information only. EACH UNIBANK SHAREHOLDER SHOULD CONSULT HIS OR HER OWN TAX
ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PROPOSED
MERGER, INCLUDING THE APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER
TAX LAWS.

Accounting Treatment
- --------------------

         The Merger is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. The pro forma results of this
accounting treatment are shown in the unaudited pro forma financial information
appearing elsewhere in this Proxy Statement/Prospectus. See "PRO FORMA FINANCIAL
INFORMATION."

         As noted above, it is a condition to the obligation of Bancshares and
UniBank to consummate the Merger that Bancshares shall have received a letter
from its auditors, Crowe, Chizek and Company LLP, to the effect that the Merger
will qualify as a pooling of interests transaction under generally accepted
accounting principles. Among the conditions which must be met in order for the
Merger to qualify for "pooling of interests" accounting treatment, generally
accepted accounting principles require that, in the aggregate, no more than
3,457 UniBank Common Shares (based on 75,000 shares currently outstanding and
3,675 shares owned by Bancshares) be held by


                                      -17-
<PAGE>   31



UniBank shareholders who have exercised dissenters' rights in connection with
the Merger and demanded payment in cash for the value of their UniBank common
shares under the ORC or receive cash in lieu of fractional shares. In the event
such condition is not met, the Merger would not be consummated unless the
condition was waived by Bancshares and UniBank. Furthermore, in order to qualify
for "pooling of interests" accounting treatment, no affiliate of either
Bancshares or UniBank may reduce his or her risk relative to the Bancshares
Common Shares received in the Merger until such time as financial results
covering at least 30 days of post-merger combined operations have been
published.

Interest of Management in the Merger
- ------------------------------------

         Bancshares will offer the existing full time employees of UniBank the
opportunity to become full time employees of Citizens or one of Bancshares'
other affiliates for a minimum period of six months. In addition, Bancshares
will offer the existing part-time employees of UniBank the opportunity to become
part-time employees of Citizens or one of Bancshares' other affiliates for a
minimum period of six months; provided, however, that Citizens may determine in
its sole discretion that number of hours that the part time employees will be
scheduled to work. UniBank employees who become employees of Citizens or one of
Bancshares' other affiliates will have their years of service with UniBank and
its predecessors credited for eligibility and vesting purposes, but not for
accrual of benefit purposes, under all Bancshares' employee pension benefit
plans, (as defined in Section 3(2) of ERISA), except with respect to Bancshares'
ESOP plan.

Expenses of the Merger
- ----------------------

         Bancshares, Citizens and UniBank shall each bear its respective
expenses incurred in connection with the Merger and the transactions
contemplated thereby. Bancshares shall be responsible for all expenses incident
to obtaining requisite regulatory approvals and UniBank shall be responsible for
all amounts payable to Danielson Associates, Inc. in connection with the
Affiliation Agreement and the transactions contemplated thereby.

Regulatory Approvals
- --------------------

         Bancshares has filed the applications necessary to obtain the approval
for the Merger from the Federal Reserve Board and the Ohio Department of
Commerce (Division of Financial Institutions, Office of Banks and Savings &
Loans). The Merger may not be consummated for 15 days after approval by the
Federal Reserve Board, during which time an action may be brought by the United
States Department of Justice challenging the Merger on antitrust grounds.
Bancshares has no reason to believe the Merger will be challenged on antitrust
grounds.

Effective Time of the Merger
- ----------------------------

         As used in this Proxy Statement/Prospectus, "Effective Time" means the
date and time when the Merger becomes effective, which will occur upon the
filing with the Ohio Secretary of State of a certified copy of the Affiliation
Agreement together with a certificate of approval from the Ohio Department of
Commerce, Division of Financial Institutions, Office of Banks and Savings &
Loans in accordance with Section 1121.06 of the ORC.

Operations of UniBank After the Merger
- --------------------------------------

         Pursuant to the terms of the Affiliation Agreement, UniBank shall be
merged with and into Citizens and Citizens shall be the Resulting Bank as of the
Effective Time. The Articles of Incorporation and Code of Regulations of
Citizens shall become the Articles of Incorporation and Code of Regulations


                                      -18-
<PAGE>   32



of the Resulting Bank until thereafter duly altered, amended or repealed in
accordance with applicable law. The offices of UniBank shall become branches of
Citizens.

         Each director of Citizens immediately prior to the Effective Time shall
remain a director of the Resulting Bank and shall serve for the balance of his
term and until his successor is duly elected and qualified or until his earlier
death, resignation or removal in the manner provided in the Code of Regulations
or as otherwise provided by law. Furthermore, each person who is an officer of
Citizens prior to the Effective Time shall remain an officer of the Resulting
Bank. It is anticipated that one member of UniBank's Board of Directors, namely
H. Lee Kinney, shall serve on the Board of Directors of Citizens and Bancshares.
The members of the Board of Directors of UniBank will also be given the
opportunity to serve on the Jefferson County Advisory Board for Citizens. For
further information regarding the directors and officers of Bancshares and the
Resulting Bank, see "INFORMATION WITH RESPECT TO BANCSHARES--Management."

         In addition, each common share of Citizens issued and outstanding
immediately prior to the Effective Time shall thereafter continue to be one
common share of the Resulting Bank.

         Upon completion of the Merger, it is also anticipated that the branches
of UniBank will be operated as branches of Citizens and that the UniBank name
will continue to be featured at the UniBank main office only. The UniBank name
may also be used in other applications to be determined by Citizens.

Business Pending the Merger
- ---------------------------

         The Affiliation Agreement provides that, pending consummation of the
Merger, UniBank will continue to operate in the ordinary course. In addition,
any lending activities other than in the ordinary course, any 1-4 family unit
residential real estate loans in excess of $75,000, any equity credit lines in
excess of $50,000, any consumer installment or construction loans in excess of
$35,000 and any commercial loans in excess of $100,000 (taking into account
existing borrowings but excluding renewals) must be consented to in writing by
Bancshares, who shall respond to any request for such consent within 24 hours of
the request. Furthermore, the Affiliation Agreement provides that UniBank may
not declare, set aside, pay or make any dividend or other distribution or
payment (whether in cash, stock or property) with respect to, or purchase or
redeem, any shares of the capital stock other than (i) regular quarterly cash
dividends in an amount not to exceed the amount paid per share of UniBank Common
Shares for the same quarter during 1996, and (ii) a special year-end cash
dividend in an amount not to exceed the special year-end cash dividend paid in
1996.

         In the Affiliation Agreement, UniBank has agreed that it will not,
directly or indirectly, through any of its officers, directors, employees,
agents or advisors or other representatives or consultants, solicit or initiate
or knowingly encourage, including by means of furnishing information, any
proposals or offers from any person (other than Bancshares) relating to any
acquisition or purchase of all or a material amount of the assets of, or any
securities of, or any merger, tender offer, consolidation or business
combination with, UniBank. UniBank has agreed to promptly notify Bancshares,
orally and in writing, if any such proposal or offer is made and shall, in any
such notice, indicate the identity and terms and conditions of any proposal or
offer, or any such inquiry or contact. In the event that the UniBank
shareholders fail to approve the Affiliation Agreement and the transactions
contemplated thereby by September 12, 1998 as a result of the decision of
UniBank's Board of Directors to entertain offers from and to negotiate with a
bona fide offeree other than Bancshares, UniBank has agreed to pay Bancshares
$500,000.



                                      -19-
<PAGE>   33



Surrender of Certificates
- -------------------------

         A Letter of Transmittal, together with instructions, for use in
surrendering certificates representing UniBank Common Shares ("Old
Certificates") in exchange for Bancshares Common Shares and handling the payment
of cash in lieu of fractional shares of Bancshares Common Shares is enclosed
herewith. Shareholders should send their Old Certificates to Bancshares, as
exchange agent (the "Exchange Agent"), duly endorsed for transfer or accompanied
by a duly endorsed assignment separate from the certificate(s). If the Merger is
consummated, the Old Certificates surrendered will be exchanged for one or more
certificates representing the whole number of Bancshares Common Shares (and
payment of cash in lieu of fractional shares) based on the Exchange Ratio. Until
so surrendered, each outstanding Old Certificate shall be deemed from and after
the Effective Time for all purposes to represent only the right to receive, upon
surrender, one or more certificates for Bancshares Common Stock and cash in lieu
of fractional shares. If the Merger is not consummated, the Exchange Agent will
return any Old Certificates it has received to the persons surrendering such Old
Certificates in accordance with the Letter of Transmittal and instructions.

         If any certificates for Bancshares Common Shares are to be issued in a
name(s) other than that in which an Old Certificate surrendered or exchanged is
issued, the Old Certificate so surrendered must be properly endorsed and
otherwise in proper form for transfer. The person requesting the exchange must
affix any requisite stock transfer tax stamps to the Old Certificate
surrendered, provide funds for their purchase, or establish to the satisfaction
of the Exchange Agent that such taxes have been paid or are not applicable.

         In the event of a lost certificate, the shareholder shall provide, in
lieu of the lost certificate, an affidavit attesting to the loss of said
certificate and, if required by the Resulting Bank or the Exchange Agent, an
indemnification or bond in such reasonable amount as the Resulting Bank or the
Exchange Agent may direct. Unless and until the Old Certificates, or affidavit
and, if required by the Resulting Bank or the Exchange Agent, an indemnification
or bond in lieu thereof, are presented to the Exchange Agent, the holder thereof
shall not be entitled to receive any consideration to be paid in connection with
the Merger or any dividends payable on Bancshares Common Shares, or to exercise
any rights as a holder of Bancshares Common Shares. On or after the Effective
Time, upon surrender of the Old Certificates, or affidavit and an
indemnification or bond in lieu thereof, to the Exchange Agent, the holder
thereof will be paid the consideration to which the holder is entitled under the
Affiliation Agreement and any dividends which theretofore became payable on any
Bancshares Common Shares to which the holder is entitled. No dividends or other
distributions, if any, payable to the holders of record of Bancshares Common
Shares as of any date subsequent to the Effective Time shall be paid to any
holder of any outstanding Old Certificate until the holder thereof surrenders
such Old Certificate as provided in the Affiliation Agreement. Subject to
applicable law, no holder of an Old Certificate shall be entitled to vote or
exercise any other rights of a holder of Bancshares Common Shares.

         After the consummation of the Merger, there will be no transfers on the
stock transfer books of UniBank of any UniBank Common Shares. If, after the
consummation of the Merger, Old Certificates are properly presented to
Bancshares, they will be canceled and exchanged for the consideration specified
in the Affiliation Agreement, subject to applicable law and to the extent that
Bancshares has not paid such consideration to a public official pursuant to
applicable abandoned property laws.

Resale of Bancshares Common Shares
- ----------------------------------

         No restrictions on the sale or other transfer of the Bancshares Common
Shares issued pursuant to the Merger will be imposed solely as a result of the
Merger, except for restrictions on the transfer of shares issued to any UniBank
shareholder who may be deemed to be an "affiliate" of UniBank for purposes of
Rule 145 under the 1933 Act. Generally, "affiliates" of UniBank would include
officers,


                                      -20-
<PAGE>   34



directors and significant shareholders of UniBank. The Affiliation Agreement
requires UniBank to cause persons who could be considered to be "affiliates" to
enter into an agreement with Bancshares to the effect that the Bancshares Common
Shares to be acquired by such "affiliates" will not be sold, pledged,
transferred or otherwise disposed of except in compliance with the 1933 Act and
the rules and regulations thereunder. Sales of Bancshares Common Shares by
affiliates of Bancshares are subject to similar transfer restrictions.

         Bancshares Common Shares issued to UniBank shareholders who may be
deemed to be affiliates may be resold only (i) in transactions permitted by Rule
145 promulgated under the 1933 Act, (ii) pursuant to an effective registration
statement, or (iii) in transactions exempt from registration. Rule 145, as
currently in effect, imposes restrictions on the manner in which such affiliates
may make resales and also on the quantity of resales that such affiliates, and
others with whom they might act in concert, may make within any three month
period.

Rights of Dissenting Shareholders
- ---------------------------------

         Shareholders of UniBank are entitled to certain dissenters' rights
pursuant to Section 1701.85 of the ORC. Sections 1701.85 and 1115.19 generally
provide that shareholders of UniBank will not be entitled to such rights absent
compliance with Section 1701.85 and failure to take any one of the required
steps may result in the termination or waiver of such rights. Specifically, any
UniBank shareholder who is a record holder of UniBank Common Shares on the
Record Date and whose shares are not voted in favor of the Merger may be
entitled to be paid the "fair cash value" of such UniBank Common Shares after
the Effective Time. To be entitled to such payment, a shareholder must deliver a
written demand for payment therefor to UniBank on or before the tenth day
following the Special Meeting and must otherwise comply with Section 1701.85.
Any written demand must specify the shareholder's name and address, the number
and class of shares held by him or her on the Record Date, and the amount
claimed as the "fair cash value" of said UniBank Common Shares. See the text of
Sections 1115.19 and 1701.85 of the ORC attached as Appendix B to this Proxy
Statement/Prospectus for specific information on the procedure to be followed in
exercising dissenters' rights.

         If the Resulting Bank so requests, dissenting shareholders must submit
their share certificates to UniBank within fifteen days of such request, for
endorsement thereon by UniBank that demand for appraisal has been made and
failure to comply with such request could terminate the dissenting shareholders
rights. Such certificates will be promptly returned to the dissenting
shareholders by UniBank. If UniBank and any dissenting shareholder cannot agree
upon the "fair cash value" of the UniBank Common Shares, either may, within
three months after service of demand by the shareholder, file a petition in the
Court of Common Pleas of Jefferson County, Ohio (the "Court") for a
determination of the "fair cash value" of said UniBank Common Shares. The Court
may appoint one or more appraisers to determine the "fair cash value" and if the
Court approves the appraisers' report, judgment will be entered therefor, and
the costs of the proceedings, including reasonable compensation of the
appraisers, will be assessed or apportioned as the Court considers equitable.


                    DESCRIPTION OF BANCSHARES CAPITAL SHARES
                    ----------------------------------------

General
- -------

         Bancshares has authorized 12,000,000 Common Shares, without par value,
of which 5,897,540 are issued and outstanding and 2,250 are held in treasury.
Each outstanding Bancshares Common Share is duly authorized, validly issued,
fully paid and nonassessable. The holders of Bancshares Common Shares have one
vote per share on each matter on which shareholders are entitled


                                      -21-
<PAGE>   35



to vote and, in accordance with Ohio law, cumulative voting rights may be
requested in connection with the election of directors. Directors are elected
for staggered, three year terms. Specifically, the Board is divided into three
classes with three to four directors per class and with the members of one class
being elected annually. On liquidation or dissolution of Bancshares, the holders
of Bancshares Common Shares are entitled to share ratably in such assets as
remain after creditors have been paid.

         In addition, Bancshares has authorized 200,000 shares of serial
preferred stock ("Serial Shares"), none of which are currently outstanding. The
terms of the Serial Shares are to be established by Bancshares' Board of
Directors; therefore, if Bancshares were to issue Serial Shares in the future,
holders thereof might have preference over the holders of Bancshares Common
Shares in the event of a liquidation or dissolution and may have other rights
which are superior to or in addition to the rights of holders of Bancshares
Common Shares. Serial Shares have a par value of $10.00 per share. Bancshares
Common Shares have no par value. Holders of Bancshares Common Shares have no
preemptive rights, subscription rights or conversion rights.

         Bancshares' Board of Directors determines whether to declare dividends
and the amount of any dividends declared. Such determinations by the Board of
Directors take into account Bancshares' financial condition, results of
operations and other relevant factors. While management expects to maintain its
policy of paying regular cash dividends, no assurances can be given that any
dividends will be declared, or, if declared, what the amount of such dividends
will be. See "INFORMATION WITH RESPECT TO BANCSHARES--Market Price of Bancshares
Common Shares."

         Bancshares is the transfer agent and registrar for Bancshares Common
Shares.

Description of Control Share Acquisition Provisions
- ---------------------------------------------------

         Bancshares' Articles of Incorporation restrict certain acquisitions of
Bancshares Common Shares that meet the definition of a Control Share
Acquisition. A Control Share Acquisition is defined as the acquisition, directly
or indirectly, by any person, of Bancshares Common Shares that, when added to
all other shares of Bancshares in respect of which such person may exercise or
direct the exercise of voting power, would entitle such person, immediately
after such acquisition, directly or indirectly, to exercise or direct the
exercise of the voting power in the election of directors within any of the
following ranges of such voting power:

           (a)  One-fifth or more but less than one-third of such voting power;

           (b)  One-third or more but less than a majority of such voting power;

           (c) A majority or more of such voting power.

The Articles of Incorporation provide for certain exceptions to this definition,
such as good faith acquisitions not for the purpose of circumventing the
Articles of Incorporation, bequests, inheritances and gifts, pledges or other
security interests created in good faith and not for the purpose of
circumventing the Articles of Incorporation, or pursuant to certain
shareholder-approved mergers, consolidations or majority share acquisitions. If
an acquisition of Bancshares Common Shares qualifies as a Control Share
Acquisition, authorization for such transaction must be obtained at a special
shareholder meeting held in accordance with procedures contained in the Articles
of Incorporation. If these procedures are violated, the person making such
acquisition loses certain shareholder rights.



                                      -22-
<PAGE>   36



Procedures

         In order to obtain authorization for a Control Share Acquisition, the
person proposing to make such acquisition must deliver a notice to Bancshares
(the "Notice") including the following information:

                  (a) The identity of the person who is giving the Notice;

                  (b) A statement that the Notice is given pursuant to the
         Articles of Incorporation;

                  (c) The number and class of shares of Bancshares owned,
         directly or indirectly, by the person who gives the Notice;

                  (d) The range of voting power under which the proposed Control
         Share Acquisition would, if consummated, fall;

                  (e) A description in reasonable detail of the terms of the
         proposed Control Share Acquisition; and

                  (f) Reasonable evidence that the proposed Control Share
         Acquisition, if consummated, would not be contrary to law and that the
         person who is giving the Notice has the financial capacity to make the
         proposed Control Share Acquisition.

Within ten days of receiving the Notice, the Board of Directors must call a
special meeting of shareholders to be held not later than 50 days after receipt
of the Notice. The purpose of the special meeting of shareholders is to consider
the proposed Control Share Acquisition; provided, that the Board of Directors
shall have no obligation to call such meeting if they make a determination
within ten days after receipt of the Notice (i) that the Notice was not given in
good faith, (ii) that the proposed Control Share Acquisition would not be in the
best interests of Bancshares and its shareholders or (iii) that the proposed
Control Share Acquisition could not be consummated for financial or legal
reasons.

Requirements for Approval

         The person who delivered the Notice may make the proposed Control Share
Acquisition if both of the following occur: (i) the shareholders authorize such
acquisition at the special meeting called by the Board of Directors for that
purpose, at which a quorum is present, by an affirmative vote of a majority of
the shares entitled to vote in the election of directors ("Voting Shares")
represented at such meeting in person or by proxy and by a majority of the
portion of such Voting Shares represented at such meeting in person or by proxy
excluding the votes of "Interested Shares"; and (ii) such acquisition is
consummated, in accordance with the terms so authorized, not later than 360 days
following shareholder authorization of the Control Share Acquisition.
"Interested Shares" are Voting Shares with respect to which any of the following
persons may exercise or direct the exercise of the voting power:

                  (a) any person whose Notice prompted the calling of the
         meeting of shareholders;

                  (b) any officer of Bancshares elected or appointed by the
         directors of Bancshares; and

                  (c) any employee of Bancshares who is also a director of
         Bancshares.



                                      -23-
<PAGE>   37



Violation of Restriction

         Bancshares Common Shares issued or transferred to any person in
violation of this restriction are valid only with respect to such amount of
shares as does not result in a violation of the Articles of Incorporation, and
such issuance or transfer is null and void with respect to the remainder of such
shares. Any such remainder of shares are called "Excess Shares." Excess Shares
are not entitled to any voting rights, are not considered to be outstanding for
quorum or voting purposes, and are not entitled to receive dividends, interest
or any other distribution with respect to the Excess Shares. Any person who
receives dividends, interest or any other distribution in respect to Excess
Shares holds the distribution as agent for Bancshares and, following a permitted
transfer, for the transferee. Any holder of Excess Shares may transfer the
Excess Shares (together with any distributions thereon) to any person who,
following such transfer, would not own shares in violation of the Articles of
Incorporation. Upon a permitted transfer, Bancshares will pay or distribute to
the transferee any distributions on the Excess Shares not previously paid or
distributed.


                   COMPARATIVE RIGHTS OF UNIBANK SHAREHOLDERS
                   ------------------------------------------

         As a consequence of the Merger, shareholders of UniBank will become
shareholders of Bancshares. The following is a summary of certain similarities
and all material differences between the rights of holders of UniBank Common
Shares and the rights of holders of Bancshares Common Shares. As UniBank is a
bank and Bancshares is a corporation, both organized under the laws of Ohio,
these differences arise from various provisions of the Articles of Incorporation
and Code of Regulations of each of UniBank and Bancshares.

         The following summary does not purport to be a complete statement of
the rights of shareholders under the UniBank Articles of Incorporation ("UniBank
Articles") and the Code of Regulations of UniBank as compared with the rights of
Bancshares shareholders under the Bancshares Articles of Incorporation
("Bancshares Articles") and the Bancshares Codes of Regulations, or a complete
description of the specific provisions referred to herein. The summary is
qualified in its entirety by reference to the governing corporate instruments,
including the aforementioned instruments, of UniBank and Bancshares.

Voting
- ------

         Holders of both UniBank Common Shares and Bancshares Common Shares are
entitled to one vote per share. Pursuant to the UniBank Code of Regulations,
however, holders of UniBank Common Shares are not entitled to cumulative voting
for directors, whereas holders of Bancshares Common Shares are entitled to
cumulative voting for directors. Moreover, pursuant to the UniBank Code of
Regulations, the affirmative vote of the holders of record of sixty (60%)
percent of the issued and outstanding UniBank Common Shares in attendance or
represented at any meeting at which a quorum is present is required for
mergers, consolidations and the disposition of all or substantially all of
UniBank's assets, and all other UniBank shareholder acts. According to the
Bancshares Articles, however, the affirmative vote of two thirds of the shares
entitled to vote is required for mergers, consolidations and the disposition of
all or substantially all of Bancshares' assets. The Bancshares Articles also
provide for special voting procedures in the event of a Control Share
Acquisition. See "DESCRIPTION OF BANCSHARES CAPITAL STOCK -- Description of
Control Share Acquisition Provisions."

<PAGE>   38



Preemptive Rights
- -----------------

         Holders of UniBank Common Shares have preemptive rights to purchase
UniBank Common Shares to be issued by UniBank. The Bancshares Articles have
eliminated preemptive rights for holders of Bancshares Common Shares.

Directors
- ---------

         The UniBank Code of Regulations provides for no fewer than nine (9) or
more than fifteen (15) directors, all of the same class. The Bancshares Code of
Regulations provides for no fewer than nine (9) or more than eleven (11)
directors who are elected for staggered three year terms.

Authorized Shares
- -----------------

         The UniBank Articles provide for 75,000 shares of common stock with a
par value of ten dollars ($10.00) per share. The Bancshares Articles provide for
12,000,000 shares of common stock, without par value, and 200,000 shares of
serial preferred stock, with a par value of ten dollars ($10.00) per share. The
rights of the holders of the serial preferred stock when issued could be
superior to the rights of the holders of the Bancshares Common Shares.

Shareholder Meetings
- --------------------

         A special meeting of the UniBank shareholders can be called by the
UniBank Board of Directors or by the Chairman or President of the bank. A
special meeting may also be called at the written request of holders of record
of not less than forty percent (40%) of the UniBank Common Shares. A special
meeting of the Bancshares shareholders can be called by the Bancshares Board of
Directors, the Chairman of the Board, the President, a vice president or by
shareholders owning fifty percent (50%) or more of the Bancshares Common Shares.

         The UniBank Code of Regulations contain no provisions for shareholder
proposals. Bancshares Code of Regulations require a shareholder to notify
Bancshares of any proposal at least sixty (60) days prior to the shareholders
meeting. Such notice must include a brief description of the proposal, an
explanation for why it is being proposed, and the name, share ownership and
material interest of the shareholder in the proposal, if any.


                         PRO FORMA FINANCIAL INFORMATION
                         -------------------------------

Citizens Bancshares and UniBank
- -------------------------------

         The following unaudited pro forma condensed consolidated balance sheet
as of September 30, 1997 and the unaudited pro forma condensed consolidated
statements of income for the nine months ended September 30, 1997 and 1996, and
for the years ended December 31, 1996, 1995 and 1994 have been prepared to
reflect Bancshares' acquisition of UniBank as if the acquisition had occurred on
September 30, 1997 with respect to the balance sheet and as of January 1, 1994
with respect to the income statements, in each case giving effect to the pro
forma adjustments described in the accompanying notes. The pro forma adjustments
are based on estimates made for the purpose of preparing these pro forma
financial statements. The actual adjustments to the accounts of Bancshares will
be made based on the underlying historical financial data at the time of the
transaction. Bancshares' management believes that the estimates used in these
pro forma financial statements are reasonable under the circumstances.

         The pro forma condensed consolidated financial information has been
prepared based on the "pooling of interests" method of accounting assuming
945,056 Bancshares Common Shares will be


                                      -25-
<PAGE>   39



issued and that no UniBank shareholders will dissent with respect to the Merger.
This information will vary if any UniBank shareholders dissent or if the total
value of Bancshares Common Shares to be issued for a UniBank Common Share plus
cash in lieu of fractional shares is less than 2.7 times the book value of a
UniBank Common Share at December 31, 1997. For a discussion of the pooling of
interests method of accounting, see "PROPOSED Merger--Accounting Treatment" and
"Other Provisions of the Affiliation Agreement."

         The unaudited pro forma condensed consolidated balance sheet as of
September 30, 1997 is not necessarily indicative of the combined financial
position had the Merger been effective at that date. The unaudited pro forma
condensed consolidated statements of income are not necessarily indicative of
the results of operations that would have occurred had the Merger been effective
at the beginning of the periods indicated, or of the future results of
operations of Bancshares. These pro forma financial statements should be read in
conjunction with the historical financial statements and the related notes
incorporated elsewhere in this Proxy Statement/Prospectus. See also "Pro Forma
Financial Information - Citizens Bancshares, Inc., UniBank and Century Financial
Corporation."

         No adjustments to the pro forma financial statements were necessary to
conform accounting methods as contemplated by Accounting Principles Board
Opinion No. 16.

Citizens Bancshares, Inc., UniBank and Century Financial Corporation
- --------------------------------------------------------------------

         On December 3, 1997, Bancshares entered into an Agreement and Plan of
Merger with Century Financial Corporation ("Century"), which Agreement calls
for the affiliation of Century and Bancshares. The affiliation will be effected
by means of a merger of Century with and into Bancshares, in which each
outstanding share of Century Common Stock will be converted into 0.425 shares
of Bancshares Common Shares, in a tax free exchange, subject to certain
adjustments based on the then current closing price of Bancshares Common Shares
on the NASDAQ National Market System. The following pro forma information is
presented because Bancshares believes it is probable the transaction with
Century will occur. See "Information with Respect to Bancshares - Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations for the Quarter Ended September 30, 1997 -- Recent Developments" for
a more detailed description of Bancshares' pending acquisition of Century,
which is expected to be consummated on or about June 30, 1998.

         The following unaudited pro forma condensed consolidated balance sheet
as of September 30, 1997 and the unaudited pro forma condensed consolidated
statements of income for the nine months ended September 30, 1997 and 1996, and
for the years ended December 31, 1996, 1995 and 1994 have been prepared to
reflect Bancshares' potential acquisition of UniBank and Century Financial
Corporation as if the acquisitions had occurred on September 30, 1997 with
respect to the balance sheet and as of January 1, 1994 with respect to the
income statements, in each case giving effect to the pro forma adjustments
described in the accompanying notes. The pro forma adjustments are based on
estimates made for the purpose of preparing these pro forma financial
statements. The actual adjustments to the accounts of Bancshares will be made
based on the underlying historical financial data at the time of the
transactions. Bancshares' management believes that the estimates used in these
pro forma financial statements are reasonable under the circumstances.

         The pro forma condensed consolidated financial information has been
prepared based on the "pooling of interests" method of accounting. It has been
assumed that, in the UniBank transaction, 945,056 Bancshares Common Shares will
be issued and that no UniBank shareholders will dissent with respect to the
Merger. This information will vary if any UniBank shareholders dissent or if the
total value of Bancshares Common Shares to be issued for a UniBank Common Share
plus cash in lieu of fractional shares is less than 2.7 times the book value of
a UniBank Common Share at December 31, 1997. For a discussion of the pooling of
interests method of accounting, see "PROPOSED Merger--Accounting Treatment" and
"Other Provisions of the Affiliation Agreement." It has also been assumed that,
in the Century transaction, 2,234,934 Bancshares Common Shares will be issued
(including in connection with the exercise of outstanding options to purchase
Century Common Shares) and that no Century shareholders will dissent. This
information will vary if any Century shareholders dissent or if the Average NMS
Closing Price (as defined in the Agreement and Plan of Merger between Bancshares
and Century) is greater than $67.50 or less than $56.50.

         The unaudited pro forma condensed consolidated balance sheet as of
September 30, 1997 is not necessarily indicative of the combined financial
position had the acquisitions been effective at that date. The unaudited pro
forma condensed consolidated statements of income are not necessarily indicative
of the results of operations that would have occurred had the acquisitions been
effective at the beginning of the periods indicated, or of the future results of
operations of Bancshares. These pro forma financial statements should be read in
conjunction with the historical financial statements and the related notes
incorporated elsewhere in this Proxy Statement/Prospectus.

         No adjustments to the pro forma financial statements were necessary to
conform accounting methods as contemplated by Accounting Principles Board
Opinion No. 16.

                     INFORMATION WITH RESPECT TO BANCSHARES
                     --------------------------------------

Business
- --------

         Bancshares is a bank holding company organized in 1982 under the laws
of the State of Ohio and registered with the Federal Reserve Board pursuant to
the Bank Holding Company Act of 1956, as amended, and engaged in the business of
commercial and retail banking. These activities account for substantially all of
Bancshares revenue, operating income and assets. Bancshares is a holding company
for two wholly owned subsidiary banks, a wholly owned reinsurance company and a
wholly owned courier company. Citizens, owned by Bancshares since 1982, was
organized and chartered under the banking laws of the State of Ohio in 1902.
Citizens is an insured bank under the Federal Deposit Insurance Act ("FDIA").
This subsidiary accounts for approximately 95% of Bancshares' consolidated
assets. The primary market area for Citizens is eastern Ohio and consists of all
of Columbiana County, all of Carroll County, portions of Stark and Mahoning
counties and the northern 75% of Jefferson County. A secondary market is the
southern portion of Jefferson County, the panhandle of West Virginia north of
Follansbee, and a smaller portion of Pennsylvania south of Beaver and west of
Darlington to the Ohio border. Citizens competes not only with locally owned
commercial banks and savings and loans, but also with larger regional financial
institutions in offering consumer and commercial financial service products.
FNB, owned by Bancshares since January 1, 1990, was organized and chartered as a
national banking association under the laws of the United States on December 29,
1969 and formally opened for business on January 2, 1970. FNB is insured under
the FDIA and accounts for approximately four percent of Bancshares' consolidated
assets. FNB's primary market area is Hancock County, West Virginia, with overlap
in the East Liverpool, Ohio market. FNB competes with locally owned commercial
banks, credit unions and savings and loan associations. Freedom Financial Life
Insurance Company ("Freedom Financial"), owned by Bancshares since August, 1985,
was organized and chartered under the laws of the State of Arizona in that same
year. Freedom Financial provides credit life and accident and health insurance
coverage to Citizens' and FNB's loan customers. Freedom Financial accounts for
less than one percent of Bancshares' consolidated assets. Freedom Express, Inc.
("Freedom Express"), owned by Bancshares since August 5, 1994, was organized and
chartered under the laws of the State of Ohio in 1984. Freedom Express
transports papers and documents between and among Ohio, Pennsylvania and West
Virginia. Freedom Express accounts for less than one percent of Bancshares'
consolidated assets. As of September 30, 1997 and December 31, 1996, Bancshares
had total consolidated assets of approximately $1.0 billion and $947.9 million
and total shareholders' equity of $99.9 million and $89.7 million, respectively.
Bancshares' principal executive offices are located at 10 East Main Street,
Salineville, Ohio 43945. The telephone number of Bancshares' executive offices
is (330) 679-2328.

         On December 3, 1997, Bancshares entered into an Agreement and Plan of
Merger with Century Financial Corporation ("Century"), which agreement calls for
the affiliation of Century and Bancshares. The affiliation will be effected by
means of a merger of Century with and into Bancshares, in which each outstanding
share of Century common stock will be converted into 0.425 shares of Bancshares
common shares, in a tax free exchange, subject to certain adjustments based on
the then average closing price of Bancshares common shares on the NASDAQ
National Market System. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations for the Quarter Ended September 30, 1997 -
Recent Developments" for a more detailed description of the affiliation.

         In order to assess the Year 2000 issue (the fact that many computer
applications, if not corrected, could fail or create erroneous results by or at
the year 2000 because many existing computer programs use only two digits to
identify a year in the date field and these programs were not designed or
developed while considering the impact of the upcoming change in the century),
Bancshares has established a project group that represents functional areas to
be affected by Year 2000 changes. The


                                      -43-
<PAGE>   57



Year 2000 project group meets regularly to review Bancshares' progress. All data
processing systems have been identified and all major systems and most lesser
systems have been assessed for Year 2000 compliance. This assessment indicates
that there will be no material impact on Bancshares' operations or budgets to
bring systems into compliance by year end 1998. Most security and environmental
systems have also been assessed with no material impact indicated.

as of September 30, 1997 compared to December 31, 1996 and Results of Operations
for the quarter and nine months ended September 30, 1997, as compared to the
same periods ended September 30, 1996, is included in Bancshares' Form 10-Q for
the quarter ended September 30, 1997, which accompanies this Proxy
Statement/Prospectus and is incorporated herein by reference. Such discussion
should be read in conjunction with (i) the interim consolidated financial
statements and the footnotes thereto included in the Form 10-Q and (ii)
Management's Discussion and Analysis of Financial Condition and Results of
Operations for the Year Ended December 31, 1996 included in Bancshares' 1996
Annual Report which also accompanies this Proxy Statement/Prospectus and is
incorporated by reference.

Recent Developments

         On November 17, 1997, Century Financial Corporation ("Century"), of
Rochester, Pennsylvania, and Bancshares entered into a letter of intent (the
"Letter of Intent") calling for the affiliation of Century with Bancshares. In
furtherance of the potential acquisition, Century granted to Bancshares a
binding option, exercisable under certain conditions, to purchase up to 19.9% of
Century's outstanding common shares.

         On December 3, 1997, Century and Bancshares executed a definitive
Agreement and Plan of Merger (the "Century Agreement"), which provides for the
affiliation of Century with Bancshares. The Century Agreement provides that the
affiliation will be effected by means of a merger of Century with and into
Bancshares. In the merger, each outstanding share of Century common stock, par
value $0.835 per share, will be converted into 0.425 shares of Bancshares common
shares, in a tax-free exchange, subject to certain adjustments based on the then
average closing price of Bancshares common shares on the NASDAQ National Market
System.

         The Century Agreement further provides that, following the merger, the
employment of no former Century employee will be terminated, other than for
cause, for a period ending December 31, 1998. Moreover, three former directors
from Century's Board of Directors will be invited to join the Board of Directors
of Bancshares, one of whom will be designated for membership on the Board's
Executive Committee. Four former Century Board members will also be invited to
join the Citizens' Board of Directors. The remaining former Century Board
members will be asked to serve on the Century Advisory Board.

         The Century Agreement may only be terminated in one of the following
manners: (i) by mutual consent of the parties; (ii) by Century if the Average
NMS Closing Price (as that term is defined in the Century Agreement) is less
than $46.50; (iii) by Century if (a) the Average NMS Closing Price is less than
$54.25 and (b) Bancshares' Average NMS Closing Price is more than ten percent
lower than the average of the NMS Closing Price of an index of selected,
publicly traded, peer group, commercial banking institutions in Ohio,
Pennsylvania and West Virginia; or (iv) by either party if the transactions
contemplated by the Century Agreement are not consummated by September 30, 1998
or in the event of a material breach by the other party.

         Completion of the transactions contemplated by the Century Agreement is
contingent upon approval of the Century Agreement by the shareholders of both
Century and Bancshares and upon the approval of certain regulatory authorities.

         Dividends by UniBank may be declared by UniBank by its Board of
Directors out of surplus. An Ohio bank must generally maintain surplus in an
amount which is equal to the amount of its capital. In addition to other
limitations under Ohio law with respect to the payment of dividends, approval of
the Division is required for the declaration of dividends by an Ohio bank if the
total of all dividends declared by such bank in any year exceeds the total of
its net profits (as defined in Section 1117.02 of the ORC) for that year
combined with its retained net profits for the preceding two years, less any
required transfers to surplus or a fund for the requirement of any preferred
stock or capital securities.

         If, in the opinion of the applicable federal bank regulatory authority,
a bank under its jurisdiction is engaged in or is about to engage in an unsafe
or unsound practice (which, depending on the financial condition of the bank,
could include the payment of dividends), such authority may require, after
notice and hearing, that such bank cease and desist from such practice. In
addition, the Federal Reserve Board and the FDIC have issued policy statements
which provide that banks should generally only pay dividends out of current
operating earnings. Finally, the federal bank regulatory authorities have
established guidelines with respect to the maintenance of appropriate levels of
capital by a bank under their jurisdiction. Compliance with standards set forth
in such policy statements and guidelines could limit the amounts which a bank
can pay as dividends. For discussions of the restrictions on the payment of
dividends on UniBank Common Shares, see INFORMATION WITH RESPECT TO UNIBANK
Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."

Management's Discussion and Analysis of Financial Condition and Results of 
- -------------------------------------------------------------------------- 
Operations.
- -----------

Introduction

     This discussion is intended to focus on certain financial information
regarding UniBank. The purpose of this discussion is to provide the reader with
a more thorough understanding of the financial statements. This discussion
should be read in conjunction with the financial statements and accompanying
notes contained elsewhere in this Proxy Statement/Prospectus.

     Management of UniBank is not aware of any market or institutional trends,
events or uncertainties that are expected to have a material effect on
liquidity, capital resources or operations except as discussed herein. Also,
management is not aware of any current recommendations by its regulatory
authorities that would have such effect if implemented.

Overview - Rate and Volume Variances

     The reported results of UniBank are dependent on a variety of factors,
including the general interest rate environment, competitive conditions in the
industry, governmental policies and regulations and conditions in the markets
for financial assets. Net interest income is the largest component of UniBank's
net income, and consists of the difference between income generated on
interest-earning assets and interest expense incurred on interest-bearing
liabilities. Net interest income is primarily affected by the volumes, interest
rates and composition of interest-earning assets and interest-bearing
liabilities.

     Average Balances and Yields. The following tables present for the periods
indicated, the total amount of interest income from average interest-earning
assets and the resultant yields, as well as the interest expense on average
interest-bearing liabilities, expressed both in dollars and rates, and the net
interest margin. Net interest margin refers to the net interest income divided
by total interest-earning assets and is influenced by the level and relative mix
of interest-earning assets and interest-bearing liabilities. All average
balances are daily average balances. Non-accruing loans are included in average
loan balances.

Comparison of Operating Results for Nine Months Ended September 30, 1997 and
1996

         Net Income. Net income for the nine months ended September 30, 1997 was
$1,731,000 a $265,000 or 18.1% increase from $1,466,000 reported for the
comparable period in 1996. Earnings per share for the nine months ended
September 30, 1997 was $23.08, an increase of 18.1% over earnings per share of
$19.55 for the nine months ended September 30, 1996. This strong increase in
earnings was the result of increases in net interest income and other income and
a reduction in the provision for loan losses. These effects were partially
offset by an increase in other expenses and an increase in the provision for
income taxes.

         Interest Income. Interest income for the nine months ended September
30, 1997 was $11,055,000, up 16.5% from $9,486,000 for the nine months ended
September 30, 1996. This increase was the result of a large increase in earning
assets and an increase in the average rate earned during the period. The
increase in earning assets was due to the funds received in connection with the
branch purchases which was utilized to purchase and originate loans and
securities purchases.

         Interest Expense. Interest expense rose to $4,853,000 for the nine
months ended September 30, 1997 from $4,079,000 for the comparable period in
1996, an increase of $774,000 or 19.0%. The rise in interest expense was due to
an increase in the average balance of interest-bearing liabilities, primarily
deposits, and an increase in the average cost of funds.

         Net interest income increased 14.7% to $6,202,000 in the first nine
months of 1997, up from $5,407,000 in the same period of 1996. This increase
resulted from a 15.5% increase in average earning assets which was slightly
offset by a decrease in the net interest margin (FTE) to 4.27% in the first nine
months of 1997, down 2 basis points from 4.29% for the comparable period in
1996. UniBank benefitted from increased yields on interest-earning assets, but
the benefit was more than offset by increased rates on interest-bearing
liabilities.

         Provision for Loan Losses. The provision for loan losses decreased to
$25,000 for the nine months ended September 30, 1997, down 37.5% from $40,000
for the same period in 1996. This decrease was primarily the result of a
reduction in the level of non-performing loans.

         Other Income. Other income was $669,000 for the nine months ended
September 30, 1997, an increase of $50,000 or 8.1% over $619,000 reported for
the comparable period in 1996. This increase was the result of a 10.9% increase
in service charges on deposit accounts and other fees as well as a modest
increase in other income.

         Other Expense. Other expense was $4,325,000 for the nine months ended
September 30, 1997 compared to $3,857,000 for the comparable period in 1996, or
a 12.1% increase. Other expenses increased primarily as a result of a $121,000
or 26.9% increase in occupancy primarily due to the impact of the additional
branches acquired during 1997. In addition, other expenses increased $311,000 or
23.5% due to expenses related to the branch acquisitions, including amortization
of the intangible expenses, due to expenses related to the proposed merger and
due to general increases in other expenses. Future other expense will increase
due to the impact of the amortization of the $1.75 million intangible asset
related to the branch purchases.

         Provision for Income Taxes. Provision for income taxes was $790,000 for
the nine months ended September 30, 1997, a 19.2% increase from $663,000 for the
first nine months of 1996. This was the result of an increase in pretax income
as well as an increase in UniBank's effective tax rate of 31.3% for the first
nine months of 1997, up from 31.1% for the first nine months of 1996.

Comparison of Operating Results for Years Ended December 31, 1996 and 1995

         Net Income. Net income for 1996 was $2,118,000, as compared to
$1,963,000 for 1995, an increase of $155,000 or 7.9%. Earnings per share for
1996 was $28.24 up from $26.18 for 1995. The increase in net income was
primarily due to the decrease in the provision for loan losses and increase in
other income and was partially offset by the increase in interest expense and
the increase in other expenses.

         Interest Income. Interest income for 1996 was $12,862,000, an increase
from $12,282,000 in 1995. This is an increase of $580,000 or 4.7%. This increase
was primarily due to an increase in average interest-earning assets offset by a
18 basis point decrease in the yield on earning assets in 1996 from 1995.
Interest income also increased partially due to a shift in the composition of
interest-earning assets including an increase in higher yielding loans.

         Interest Expense. Total interest expense increased $714,000 or 14.8% to
$5,528,000 in 1996 from $4,814,000 in 1995. This increase was due a 20 basis
point increase in interest rates paid and due to a $11,743,000 or 8.5% increase
in the amount of average interest-bearing liabilities. Most of the increase was
from time deposits, due both to an increase in volume and an increase in rates
paid.

         Provision for Loan Losses. The provision for loan losses decreased to
$40,000 in 1996 from $240,000 in 1995, a decrease of $200,000 or 83.3%. UniBank
was able to reduce the provision for loan losses due to its improved charge-off
experience in 1996 and a reduction in nonperforming loans from the 1995 and 1994
year end levels. The Bank had net recoveries of $47,000 in 1996, a decline from
charge-offs of $1,377,000 in 1995.

         Other Income. Other income totaled $1,193,000 in 1996, an increase of
$729,000 or 157.1% from $464,000 reported in 1995. Service charges and fees on
deposit accounts increased by $90,000 or 19.8% in 1996 to $545,000 from $455,000
in 1995, due a general increase in fees. Other income increased dramatically to
$648,000 in 1996 from $164,000 in 1995, a difference of $484,000 due to $460,000
of rental income from a REO property acquired in 1996. The REO was sold in 1997
and the rental income is not expected to continue in future periods. In
addition, other income increased as a

result of no security sales in 1996 versus security losses of $155,000 on the
sale of securities available for sale in 1995.

         Other Expense. Other expenses were $5,398,000 in 1996 an increase of
$543,000 or 11.2% from $4,853,000 in 1995. This increase was primary due to the
increase in the salaries and employee benefits which increased by $257,000 or
10.2% to $2,775,000 in 1996 from $2,518,000 in 1995. Other expenses increased
$254,000 primarily due to the writedown of REO of $260,000 in 1996, but was
partially offset by a $191,000 decrease in the FDIC assessment.

         Provision for Income Taxes. The provision for income taxes increased to
$973,000 in 1996 from $876,000 in 1995, a $97,000 or 11.1% increase. UniBank's
effective tax rate in 1996 was 31.5% in 1996 and 30.8% in 1995.

Comparison of Operating Results for the Years Ended December 31, 1995 and 1994

         Net Income. Net income for 1995 was $1,963,000, an 11.3% increase over
earnings for 1994 of $1,763,000. Earnings per share reported in 1995 were
$26.18, up 11.4% from $23.51 for 1994. This increase in net income was the
result of the combination of an increase in net interest income and a decrease
in the provision for loan losses. These contributors to the increase in earnings
were partially offset by a decrease in other income and an increase in other
expenses.

         Interest Income. Interest income increased $1,284,000 or 11.7% in 1995
to $12,282,000, up from $10,998,000 in 1994. The increase is primarily due to a
77 basis point increase in the yield for earning assets in 1995 from 1994 and
due to a change in the mix of interest earning assets. To a lesser degree,
interest income increased as a result of the increase in average earning assets
to $157,843,000 in 1995 from $157,270,000 in 1994. Loans, the largest component
of interest earning assets and the highest yielding assets, increased $9,204,000
from an average loan balance of $84.3 million in 1994 to $85.7 million in 1995.

         Interest Expense. Total interest expense was $4,814,000 in 1995
compared to $4,111,000 for the year ended December 31, 1994. This $703,000 or
17.1% increase occurred with almost no change to the average interest bearing
liabilities, which was at $138,484 in 1995 an increase from $138,635 in 1994, a
difference of only 0.1%. The increase in interest expense was primarily due to
the increased rates paid for time deposits and a change in the mix from lower
rate demand and savings deposits to the higher rate time deposits.

         Provision for Loan Losses. The provision for loan losses decreased to
$240,000 in 1995 from $260,000 in 1994, a difference of $20,000 or 7.7%. The
decrease in the provision was due to management's evaluation of the adequacy of
the allowance for loan losses which was determined sufficient in part due to the
$1.2 million provision recorded in 1993 due to a significant problem credit
relationship. Commercial loan charge-offs in 1995 consisted primarily of two
credit relationships. One credit was secured by a personal residence which the
Bank foreclosed on in 1995. The value of the property was determined to be
substantially below the appraised value of the property when the loan was
granted and the Bank charged-off $975,000 at the time of foreclosure. This
credit was identified as a problem loan in 1993 at which time management
provided $1.1 million to the allowance. The second credit relationship resulted
in a $325,000 charge-off after a commercial business declared bankruptcy. Both
loans were identified as problem loans prior to 1995 and were classified as
non-accrual loans at December 31, 1994.

         Other Income. For the year ended December 31, 1995, other income was
$464,000, down $294,000 or 38.8% from $758,000 for the prior year. This decrease
was primarily the result of the $155,000 loss on securities sold and the result
of a decrease in other income of $36,000 or 18.0%. The decline was partially
offset by the 12.9% increase in service charges and fees.

         Other Expense. Other expenses increased to $4,853,000 in 1995 from
$4,823,000 in 1994, an increase of $77,000 or 0.6%. The rise in other expense
was due to an increase of $226,000 or 9.9% in salaries and employee benefits,
offset by a $123,000 or 6.6% decrease in other expenses.

         Provision for Income Taxes. The provision for income taxes increased in
1995 to $876,000, up $77,000 or 9.6% from $799,000 in 1994. The effective tax
rate in 1995 is 30.9% down from 31.2% in 1994.

         Asset Quality - Non-Performing Assets. Non-performing loans consist of
loans past due 90 days or more and loans for which the accrual of interest has
been discontinued. Non-performing loans totaled approximately $304,000 or .31%
of total loans at December 31, 1996, as compared to $224,000 or .24% of total
loans at December 31, 1995 and $3,523,000 or 3.94% at December 31, 1994.
Non-accrual loans in 1994 consisted primarily of two credit relationships.
Charge-offs for the deficiencies were recorded in 1995 and 1996 and the
collateral had been liquidated by early 1997. The allowance for loan losses as a
percentage of non-performing loans was 343.71%, 389.29% and 59.44% at year end
1996, 1995 and 1994, respectively. The following table sets forth non-accrual,
past due and restructured loans at December 31:

The Bank did not identify any loans as impaired at or during the year ended
December 31, 1996 and at December 31, 1995. The average balance of impaired
loans during 1995 was $2,640,000. Interest income recognized on impaired loans
during 1995 was $128,000, all on a cash basis.

         The policy for placing loans on nonaccrual status is to cease accruing
interest on loans when management believes that the collection of interest is
doubtful, or when loans are past due as to

                                     - 62 -

<PAGE>   76



principal or interest ninety days or more, except that in certain circumstances
interests accruals are continued on loans deemed by management to be fully
collectible. In such cases, the loans are individually evaluated in order to
determine whether to continue income recognition after ninety days beyond the
due dates. When loans are charged-off, any interest accrued in the current
fiscal year is charged against interest income.

         Potential Problem Loans. As of December 31, 1996, there were
approximately $2,440,000 of loans representing the remaining balances of loans
classified as substandard for regulatory purposes that have not been disclosed
above as a nonperforming or impaired loan. These loans and their potential loss
exposure have been considered in management's analysis of the adequacy of the
allowance for loan losses. These loans do not represent trends or uncertainties
which management reasonably expects will materially impact future operating
results, liquidity, or capital resources.

         Foreign Outstanding. There were no foreign loans outstanding for any
year presented.

         Loan Concentrations. Most of UniBank's business activity is with
customers located in Eastern Ohio. As of December 31, 1996, there were no other
concentrations of loans greater than 10% of total loans which were not otherwise
disclosed as a category of loans pursuant to III A. above.

         Other Interest Bearing Assets. As of December 31, 1996, there were no
other interest bearing assets that would be required to be discussed in the
foregoing tables or if such assets were loans.

         Allowance and Provision for Loan Losses. The allowance for loan losses
is maintained at a level considered adequate to cover loan losses that are
currently anticipated based on past loss experience, general economic
conditions, changes in mix and size of the loan portfolio, information about
specific borrower situations, and other factors and estimates that are subject
to change over time. Management periodically reviews selected large loans,
delinquent, impaired and other problem loans, and other selected loans. The
collectibility of these loans is evaluated by considering the current financial
position and performance of the borrower, the estimated fair value of the
collateral, UniBank's collateral position in relation to other creditors,
guarantees, and other potential sources of repayment. Management forms
judgments, which are subjective, as to the probability of loss and the amount of
loss on these loans as well as other loans in the aggregate.

         The allowance for loan losses totaled $1,045,000 at December 31, 1996,
which was 1.05% of total loans net of unearned income. This was up from $958,000
or 1.01% of total loans at December 31, 1995. This increased allowance is the
result of increases in the size of the loan portfolio and the increase in
indirect lending which has a higher degree of risk than UniBank's traditional
consumer lending and which is expected to produce a higher level of charge-offs
than UniBank's historical consumer loan charge-off experience. The allowance for
loan losses was 0.74% of total loans at September 30, 1997. The decrease was
primarily due to the decline in nonperforming commercial loans. Loans on
nonaccrual status were approximately $518,000, or .42% of outstanding balances
at September 30, 1997, compared to $108,000 or .10% of total loans at December
31, 1996. The allowance for loan losses as a percentage of non-performing loans
was 60.4% at September 30, 1997, compared to 343.8% at December 31, 1996.

Comparison of September 30, 1997 and December 31, 1996 Financial Condition

         Total assets increased to $220,077,000 at September 30, 1997, compared
to $183,368,000 at December 31, 1996, an increase of $36,709,000 or 20.0%. This
increase in assets was funded by an increase in deposits and shareholders'
equity. The increase in deposits was substantially due to the assumption of
deposits in connection with the acquisition of three branches from National City
Bank, Northeast (NCB).

         Total securities increased $28,486,000 or 61.9% to $74,530,000 at
September 30, 1997 compared to $46,044,000 at December 31, 1996, as purchases
exceeded maturities and payments received. Of the $74,530,000 of total
securities on the balance sheet at September 30, 1997, $40,562,000, or 54.4%,
are classified as held-to-maturity with the remainder classified as
available-for-sale.

         Total loans increased $24.3 million, or 24.5% to $123,497,000 at
September 30, 1997 compared to total loans outstanding at December 31, 1996 of
$99,197,000. This was primarily the result of real estate loans purchased from
a community financial institution in North Central Ohio and partially due
to stronger loan demand for commercial, mortgage and installment loans. No
significant changes in loan demand are anticipated in the near term.

         UniBank's investment in premises and equipment increased $592,000 or
21.4% from $2,762,000 at December 31, 1996 to $3,354,000 at September 30, 1997.
This was primarily due to the fixed assets purchased in connection with the
branches purchased from NCB.

         Total deposits increased $36,959,000 or 23.2%, to $196,317,000 at
September 30, 1997, compared to $159,358,000 at December 31, 1996. The increase
was substantially due to the assumption of deposit liabilities in connection
with the three branches purchased from NCB.

         UniBank's shareholders' equity increased $1,557,000 or 9.3% to
$18,397,000 at September 30, 1997. The increase was primarily due to year to
date net income of $1.7 million and decrease in the unrealized loss on
securities available for sale and was partially offset by the payment of cash
dividends. UniBank's $18,397,000 in shareholders' equity at September 30, 1997,
represented 8.4% of total assets which was a decrease from the 9.2% equity ratio
at December 31, 1997. UniBank's equity exceeded all regulatory capital
requirements at September 30, 1997.

Comparison of December 31, 1996 and 1995 Financial Condition

         Total assets of UniBank were $183,368,000 at December 31, 1996 compared
to $173,727,000 at year-end 1995, representing an increase of 5.6%. This growth
was primarily in fed funds sold and loans, which were funded by increases in
UniBank's deposits and repurchase agreements from its local customer base, and
by maturities of securities.

         Total securities decreased $566,000, or 1.2%, from $46,044,000 at
year-end 1996 to $46,610,000 at year-end 1995. The distribution within the
investment portfolio has changed as U.S. Treasury securities represented 30.3%
of the portfolio at December 31, 1996, compared to 8.7% at December 31, 1995.
The increase in U. S. Treasury securities was funded by maturities in U.S.
government agency securities which decreased from 58.4% of the portfolio at
December 31, 1995 to 36.1% at December 31, 1996.

         Gross loans totaled $99,197,000 at December 31, 1996, as compared to
$94,628,000 at year-end December 31, 1995, representing an increase of
$4,569,000 or 4.8%. The mix of UniBank's loan portfolio changed somewhat during
1996, with commercial loans comprising 35.9% of total loans at December 31,
1996, compared to 41.8% at year-end 1995. Commercial loans decreased $3,940,000,
or 10.0%, ending with a $35,574,000 balance as of December 31, 1996 as compared
to $39,514,000 at year-end 1995. The decrease was the result of increased
competition in the market and loan payments in excess of new loans.

         Installment loans increased $8,814,000 or 40.4% from December 31, 1995
to December 31, 1996. The $30,649,000 of installment loans represented 30.9% of
total loans at December 31, 1996, an increase over the 23.0% of total loans at
December 31, 1995. Substantially all of the growth in installment loans relates
to indirect automobile loans.

         Real estate loans decreased less than 1% from year-end 1995, to
$32,974,000 or 33.2% of total loans at December 31, 1996. Real estate loans
comprised 35.2% of total loans at December 31, 1995.

         Types of Loans. Total loans on the balance sheet are comprised of the
following classification at December 31:

         Total deposits increased 3.9% to $159,358,000 at December 31, 1996,
compared to $153,410,000 at December 31, 1995. Noninterest bearing balances
decreased $1,085,000 or 6.7% to $15,032,000 at December 31, 1996 as compared to
$16,117,000 at December 31, 1995. Interest bearing deposits increased $7,033,000
or 5.1% to $144,326,000 at December 31,1996 primarily due to the growth in time
deposits. Time deposits represented 43.3% of total interest bearing deposits at
December 31, 1996 compared to 39.9% at December 31, 1995.

Liquidity and Capital Resources

         Liquidity refers to UniBank's ability to generate sufficient cash to
fund current loan demand, meet deposit withdrawals, pay operating expenses and
meet the other obligations. UniBank's primary sources of liquidity are cash and
cash equivalents, which totaled $30,070,000 at year-end 1996. Net income,
securities available-for-sale, and securities and loan repayments also serve as
forms of liquidity. Other sources of liquidity which UniBank could use to help
to ensure that funds are available when needed include, but are not limited to,
the purchase of federal funds sold, adjustments of interest rates to attract
deposits, borrowings from unused lines of credit, and borrowings at the Federal
Reserve discount window. Management believes that its sources of liquidity are
adequate to meet the needs of UniBank.

         As summarized in the statements of cash flow, the most significant
investing cash flows in 1996 were purchases of available for sale securities and
held to maturity securities of $35.8 million, maturity of available for sale and
held to maturity securities of $36.3 million and an increase in net loan
obligations of $4.5 million. UniBank's primary financing activity is accepting
deposits, which accounted for a cash infusion of $5.9 million in 1996. An
additional $2.1 million of cash was provided by

                                     - 67 -

increases in securities sold under agreements to repurchase during 1996. Cash
and cash equivalents increased $5.8 million from $24.3 million at year-end 1995
to $30.1 million at year-end 1996.

         Total shareholders' equity increased from $15,572,000 at December 31,
1995 to $16,840,000 at December 31, 1996. Most of this increase resulted from
net income and was partially offset by the payment of cash dividends and the
impact of decreased market values on the fair value of securities
available-for-sale. Future volatility in shareholders' equity is expected, as
changes in market rates of interest impact the fair value of UniBank's
investment portfolio.

         Banking regulations have established minimum capital ratios for banks.
As a result, UniBank must meet a risk-based capital requirement, which defines
the two tiers of capital and compares each to UniBank's "risk-weighted assets."
UniBank's assets and certain off-balance sheet items, such as loan commitments,
are each assigned a risk factor so that assets with potentially higher credit
risk will require more capital support than assets with lower risk. These
regulations require UniBank to have a minimum total risk-based capital ratio of
8%, at least half of which must be Tier 1 capital. UniBank's Tier 1 capital is
its shareholders' equity before any gain or loss on securities
available-for-sale, while total risk-based capital includes Tier 1 capital and a
limited amount of the allowance for loan losses. In addition, a bank's leverage
ratio (which for UniBank equals its shareholders' equity, before any gain or
loss on securities available-for-sale, divided by total assets) must be
maintained at a minimum of 3% to 5%.

         The following table summarizes UniBank's capital ratios in comparison
with minimum requirements.

         The payment of dividends by UniBank to its shareholders is subject to
restrictions by its regulatory authorities, which generally limit dividends to
the current and prior two years retained earnings, as defined by regulation. In
addition, dividend payments may not reduce regulatory capital levels below the
minimum regulatory guidelines discussed above. At December 31, 1996,
approximately $3,150,000 was available for payment of dividends under the most
restrictive of these guidelines. The Merger Agreement also sets forth certain
limitations on the payment of dividends by UniBank to its shareholders. See
"PROPOSED MERGER--Business Pending the Merger."

Asset/Liability Management

         Asset/liability management is the process of managing UniBank's
exposure to changes in interest rates. The primary measure of interest rate risk
exposure is UniBank's "gap," or the difference between interest rate sensitive
assets and liabilities that mature or reprice within a certain period of

                                     - 68 -

time. In a rising interest rate environment, banks with negative interest rate
sensitivity gaps, such as UniBank, will generally experience greater increases
in their cost of funds than in the yield of their assets. Conversely, in an
environment of falling interest rates, the cost of funds of banks with negative
interest rate sensitivity gaps will decrease more rapidly than the yield on
their assets. The table below provides a measure of UniBank's interest rate
sensitivity at December 31, 1996. This table may not reflect the actual impact
of general movements in interest rates on UniBank's net interest income because
the repricing of various categories of rate sensitive assets and liabilities are
subject to other factors, such as competition, customer performance, and
management influence.

Impact of Inflation on Changing Prices

         The financial statements included herein have been prepared in
accordance with generally accepted accounting principles, which requires UniBank
to measure financial position and operating results in terms of historical
dollars, except for securities available for sale which are carried at fair
value. Changes in the relative value of money due to inflation or recession are
generally not considered.

         In Management's opinion, changes in interest rates affect the financial
condition of UniBank to a far greater degree than changes in the inflation rate.
While interest rates are greatly influenced by changes in the inflation rate,
they do not move concurrently. Rather, interest rate volatility is based on
changes in the expected rate of inflation, as well as changes in monetary and
fiscal policy. A financial institution's ability to be relatively unaffected by
changes in interest rates is a good indicator of its capability to perform in
today's volatile economic environment. In an effort to protect itself from the
effects of interest rate volatility, UniBank reviews its interest rate risk
position frequently, monitoring its exposure and taking necessary steps to
minimize any detrimental effects on the Bank's profitability.

                                 LEGAL OPINIONS
                                 --------------

         A legal opinion has been rendered by Squire, Sanders & Dempsey to the
effect that the issuance of the shares of Bancshares Common Shares offered
hereby has been duly authorized by Bancshares and that the Shares, when issued
in accordance with the Merger Agreement, will be duly issued and outstanding and
fully paid and non-assessable.


                                 INDEMNIFICATION
                                 ---------------

         The Regulations of Bancshares provide that Bancshares will indemnify
any director or officer of Bancshares or any person who is or has served at the
request of Bancshares as a director, officer or trustee of another corporation,
joint venture, trust or other enterprise (and his heirs, executors and
administrators) against expenses, including attorneys' fees, judgments, fines
and amounts paid in settlement, actually or reasonably incurred because he or
she is or was such director, officer or trustee in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative. This indemnification is to the full
extent and according to the procedures and requirements of the Ohio General
Corporation Law.

         Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers or persons controlling Bancshares
pursuant to the foregoing provisions, Bancshares has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the 1933 Act and is therefore unenforceable.

Board of Directors
UniBank
Steubenville, Ohio


We have audited the accompanying balance sheets of UniBank as of December 31,
1996 and 1995, and related statements of income, changes in shareholders' equity
and cash flows for the years ended December 31, 1996, 1995 and 1994. These
financial statements are the responsibility of the Bank'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 UniBank, as of December 31,
1996 and 1995, and the results of its operations and cash flows for the years
ended December 31, 1996, 1995 and 1994 in conformity with generally accepted
accounting principles.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of the Bank are based on generally
accepted accounting principles and conform to general practices within the
banking industry. The following is a description of the more significant
accounting policies followed by UniBank ("Bank").

ORGANIZATION: On May 17, 1985, UniBank was established as a result of a purchase
of four branch offices from AmeriTrust. Effective July 1, 1989 the Bank
purchased the assets and assumed the liabilities of the Amsterdam State Bank.
UniBank is state chartered and insured by the Federal Deposit Insurance
Corporation. It is regulated and supervised by the Ohio Division of Banks and
the Federal Deposit Insurance Corporation.

NATURE OF OPERATIONS: The Bank is engaged in the business of commercial and
retail banking and grants commercial, real estate and installment loans to
customers mainly in Jefferson County, Ohio, the eastern-central region of Ohio
and northwestern West Virginia. These communities are the source of
substantially all the Bank's deposit and loan activities. The majority of the
Bank's income is derived from commercial and retail lending activities.

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS: In preparing financial
statements, management must make estimates and assumptions. These estimates and
assumptions affect the amounts reported for assets, liabilities, revenue and
expenses, as well as the disclosures provided. Future results could differ from
the current estimates.

Areas involving the use of management's estimates and assumptions include the
allowance for loan losses, realization of deferred tax assets, fair value of
certain securities, determination and carrying value of impaired loans, the
carrying value of other real estate owned, recognition and measurement of loss
contingencies, depreciation of premises and equipment and carrying value and
amortization of intangible assets. Estimates that are more susceptible to change
in the near term include the allowance for loan losses, the carrying value of
other real estate owned and the fair value of certain securities.

SECURITIES: Held-to-maturity securities are those which management has the
positive intent and the Bank has the ability to hold to maturity, and are
reported at cost, adjusted for amortization of premiums and accretion of
discounts. Available-for-sale securities are those which the Bank may decide to
sell, if needed, for liquidity, asset-liability management or other reasons.
Available-for-sale securities are reported at fair value with unrealized gains
or losses included as a separate component of shareholders' equity, net of tax.
Realized gains or losses are determined based on the amortized cost of the
specific security sold.

                        December 31, 1996, 1995 and 1994




NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses, which is reported as a
deduction from loans, is available for loan charge-offs. This allowance is
increased by provisions charged to earnings and is reduced by loan charge-offs,
net of recoveries. The adequacy of the allowance is based on management's
evaluation of several key factors including information about specific borrower
situations, their financial condition, collateral values, current economic
conditions, changes in the mix and levels of the various types of loans, past
charge-off experience and other pertinent information. The allowance for loan
losses is based on estimates using currently available information and the
ultimate losses may vary from current estimates due to changes in circumstances.
These estimates are reviewed periodically and, as adjustments become necessary,
they are reported in earnings in the periods in which they become known.
Charge-offs are made against the allowance for loan losses when management
concludes that loan amounts are likely to be uncollectible.

Smaller balance homogeneous loans are evaluated for impairment in total. Such
loans include residential first mortgage loans secured by one- to four-family
residences, automobile, home equity and second mortgage loans less than
$200,000. Commercial loans and mortgage loans secured by other properties are
evaluated individually for impairment. When analysis of a borrower's operating
results and financial condition indicate that underlying cash flows of the
borrower's business are not adequate to meet its debt service requirements, the
loan is evaluated for impairment. Loans are generally moved to nonaccrual status
when 90 days or more past due. Loans considered to be impaired are reduced to
the present value of expected future cash flows or to the fair value of
collateral by allocating a portion of the allowance for loan losses to such
loans.

INTEREST AND FEES ON LOANS: Interest income from commercial, real estate and
installment loans is computed using the simple interest method and is credited
to income daily. The accrual of interest on loans is suspended when, in
management's opinion, the collection of all or a portion of the loan principal
has become doubtful. The carrying value of impaired loans is periodically
adjusted to reflect cash payments, revised estimates of future cash flows and
increases in the present value of expected cash flows due to the passage of
time. Increases or decreases in carrying value due to changes in estimates of
future payments or the passage of time are reported as reductions or increases
in the unallocated portion of the allowance and, to the extent necessary, the
provision for loan losses. Cash payments representing interest income are
reported as such. Other cash payments are reported as reductions in carrying
value.

Loan fees and direct costs associated with originating or acquiring loans are
deferred over the life of the related loans as an adjustment of the yield.
Premiums and discounts on acquired loans are being amortized and accreted over
the estimated lives of the related loans, as an adjustment of the yield.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

PREMISES AND EQUIPMENT: Bank premises and equipment are stated at cost less
accumulated depreciation. Depreciation is provided principally on the
straight-line method over the estimated useful lives of the assets. Costs of
major additions and improvements are capitalized, while maintenance and repairs
are charged to operating expense when incurred. The asset accounts are relieved
of the costs and the accumulated depreciation is charged with the applicable
amount when the property is disposed of or retired. Any resulting gain or loss
is reflected in the results of operations.

REAL ESTATE OWNED: Real estate acquired through foreclosure or
deed-in-lieu-of-foreclosure is initially recorded at the estimated fair value at
the date of foreclosure. The costs of preparing properties for their intended
use are capitalized, whereas costs relating to the holding of property are
expensed. Any subsequent reductions in the estimated fair value are reflected
through a charge to operations.

INCOME TAXES: The Bank follows the liability method in accounting for income
taxes. The liability method provides that deferred tax assets and liabilities
are recorded based on the difference between the tax basis of assets and
liabilities and their carrying amounts for financial reporting purposes.

PER SHARE DATA: Earnings and dividends per share amounts reflected herein have
been computed based on the weighted average shares outstanding which is 75,000
for the years ended December 31, 1996, 1995 and 1994.

STATEMENTS OF CASH FLOWS: The Bank reports net cash flows for customer loan
transactions, deposit transactions and time deposits made with other financial
institutions. The Bank considers cash, noninterest-bearing deposits with banks
and federal funds sold to be cash equivalents. For the years ended December 31,
1996, 1995, and 1994 the Bank paid interest of $5,520,000, $5,163,000, and
$4,066,000, respectively, and income taxes of $982,000, $601,000, and $850,000,
respectively.

RECLASSIFICATIONS: Certain amounts appearing in the financial statements and
notes thereto for the year ended December 31, 1995 and 1994 have been
reclassified to conform with the December 31, 1996 presentation.

NOTE 9 - COMMITMENTS AND CONTINGENCIES

The Bank 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. These
financial instruments include commitments to make loans. The Bank's exposure to
credit loss in the event of nonperformance by the other party to the financial
instrument for commitments to make loans is represented by the contractual
amount of those instruments. The Bank follows the same credit policy to make
such commitments as is followed for those loans recorded in the financial
statements.

At December 31, 1996 and 1995, the Bank had commitments to make loans at market
rates approximating $13,770,000 and $13,740,000, respectively. At December 31,
1996, approximately $12,564,000 of commitments had adjustable rates and
$1,206,000 had fixed rates.

Commitments generally have fixed expiration dates of less than twelve months.
Since many commitments to make loans expire without being used, the amount does
not necessarily represent future cash commitments. Collateral obtained upon
exercise of the commitment is determined using management's credit evaluation of
the borrower and may include real estate, vehicles, business assets or other
items.

The Bank entered into a Branch Purchase and Assumption Agreement dated October
31, 1996 with National City Bank, Northeast (NCB) to purchase from NCB, banking
offices located in Tiltonsville, Mingo Junction and East Liverpool, Ohio. The
Bank will acquire the real estate and buildings of these offices and assume
deposit liabilities of approximately $37 million in 1997. The Bank will pay NCB
premiums ranging between 2.5% to 6.5% of deposits, or approximately $2 million
on the date of closing.

NOTE 10 - FAIR VALUES OF FINANCIAL INSTRUMENTS (Continued)

For purposes of the above disclosures of estimated fair value, the following
assumptions were used. The estimated fair value for cash and cash equivalents is
considered to approximate cost. The estimated fair value of securities is based
on quoted market values for the individual securities or for equivalent
securities. Carrying value is considered to approximate fair value for loans
that contractually reprice at intervals of less than six months, cash value of
life insurance, short-term borrowings, deposit liabilities subject to immediate
withdrawal and accrued interest. The fair values of fixed rate loans, loans that
reprice less frequently than each six months and time deposits have been
approximated by a discount rate value technique utilizing estimated market
interest rates as of December 31, 1996 and 1995. The fair value of unrecorded
commitments at December 31, 1996 and 1995 is not material.

While these estimates of fair value are based on management's judgment of the
most appropriate factors, no assurance can be given that, were the Bank to have
disposed of such items at December 31, 1996 and 1995, the estimated fair values
would necessarily have been achieved at these dates, since market values may
differ depending on various circumstances. The estimated fair values at December
31, 1996 and 1995 should not necessarily be considered to apply at subsequent
dates.

Other assets and liabilities of the Bank may have value but are not included in
the above disclosures, such as property and equipment. Also, nonfinancial
instruments typically not recognized in these financial statements nevertheless
may have value, but are not included in the above disclosures. These include,
among other items, the estimated earnings power of core deposit accounts, the
earnings potential of loan servicing rights, the value of a trained work force,
customer goodwill and similar items.


NOTE 11 - REGULATORY MATTERS

The Bank is subject to regulatory capital requirements administered by federal
banking agencies. Capital adequacy guidelines and prompt corrective action
regulations involve quantitative measures of assets, liabilities and certain
off-balance-sheet items calculated under regulatory accounting practices.
Capital amounts and classifications are also subject to qualitative judgments by
regulators about components, risk weightings and other factors and the
regulators can lower classifications in certain cases. Failure to meet various
capital requirements can initiate regulatory action that could have a direct
material effect on the financial statements.

NOTE 11 - REGULATORY MATTERS (Continued)

The prompt corrective action regulations provide five classifications, including
well capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized and critically undercapitalized, although these terms are not
used to represent overall financial condition. If adequately capitalized,
regulatory approval is required to accept brokered deposits. If
undercapitalized, capital distributions are limited, as is asset growth and
expansion and plans for capital restoration are required. The minimum
requirements are:

The payment of dividends by the Bank is subject to restrictions by its
regulatory agency. These restrictions generally limit dividends to the current
and prior two years retained earnings as defined by the regulations. In
addition, dividends may not reduce capital levels below the minimum regulatory
requirements disclosed above. Under the most restrictive of these requirements,
the Bank estimates that retained earnings available for payment of dividends
approximates $3,150,000 at December 31, 1996.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                               September 30, 1997



NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

These interim financial statements are prepared without audit and reflect all
adjustments which, in the opinion of management, are necessary to present fairly
the financial position of UniBank at September 30, 1997 and its results of
operations and cash flows for the periods presented. All such adjustments are of
a normal recurring nature. The financial statements do not purport to contain
all the necessary financial disclosures required by generally accepted
accounting principles that might otherwise be necessary in the circumstances and
should be read in conjunction with the December 31, 1996 audited financial
statements.

The provision from income taxes is based upon the effective tax rate expected to
be applicable for the entire year.

Earnings per share are calculated on the basis of the weighted average number of
shares outstanding. The weighted average number of shares used in the
computation for both 1997 and 1996 was 75,000.


NOTE 2 - SECURITIES

The amortized costs and estimated fair values of investment securities are as
follows:

NOTE 4 - COMMITMENTS AND CONTINGENCIES

The Bank 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. These
financial instruments include commitments to make loans. The Bank's exposure to
credit loss in the event of nonperformance by the other party to the financial
instrument for commitments to make loans is represented by the contractual
amount of those instruments. The Bank follows the same credit policy to make
such commitments as is followed for those loans recorded in the financial
statements.

At September 30, 1997 and December 31, 1996, the Bank had commitments to make
loans at market rates approximating $11,885,000 and $13,770,000, respectively.
At September 30, 1997, approximately $9,812,000 of commitments had adjustable
rates and $2,073,000 had fixed rates.

Commitments generally have fixed expiration dates of less than twelve months.
Since many commitments to make loans expire without being used, the amount does
not necessarily represent

determined using management's credit evaluation of the borrower and may include
real estate, vehicles, business assets or other items.


NOTE 5 - ACQUISITION

On September 12, 1997, UniBank and Citizens Bancshares, Inc. ("Bancshares")
entered into a plan and agreement of merger. The transaction is structured as a
tax-free exchange of stock and is expected to be accounted for using the pooling
of interests method of accounting. The exchange ratio at which UniBank will be
exchanged for Bancshares common shares will be 13.25 shares of Bancshares stock
for each share of UniBank Stock. In no event will the exchange ratio be less
than 2.7 times the book value of the Banks equity at December 31, 1997. In the
event the book value per share exceeds $250 per share, Bancshares may elect to
terminate the agreement of merger. In addition, the bank may terminate the
merger agreement if the average NASDAQ National Market System (NMS) price of
Bancshares is 20% or more lower than the average NMS price of 24 defined
financial institutions located throughout Ohio, Pennsylvania and West Virginia.
The Bancshares common shares to be issued to the UniBank shareholders will be
registered with the Securities and Exchange Commission. The merger is expected
to be consummated during the first quarter of 1998 and is subject to approvals
by various regulatory authorities and by the shareholders of UniBank.

                                    RECITALS
                                    --------

     Bancshares and Bank desire that Bank shall be merged with and into Citizens
pursuant to an Agreement of Merger substantially in the form attached as Exhibit
A hereto and made a part hereof (the "Merger" and the "Agreement of Merger,"
respectively).

     NOW THEREFORE, in consideration of the premises and mutual covenants herein
contained, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                               PLAN OF AFFILIATION
                               -------------------

     Pursuant to this Agreement, Bancshares and Bank have agreed to a plan of
affiliation intended to result in a tax-free plan of reorganization pursuant to
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
Upon consummation of the transactions contemplated by this Agreement, at the
Effective Time (as hereinafter defined in Section 1.1), Bank will be merged into
Citizens pursuant to the terms and conditions set forth herein and in the
Agreement of Merger. Upon consummation of the Merger, the separate existence of
Bank shall cease and Citizens shall continue as the surviving corporation and
the offices of Bank will become branches of Citizens.

                                    ARTICLE I

                        THE MERGER AND THE SHARE EXCHANGE
                        ---------------------------------

     Section 1.1. EFFECTIVE TIME. As soon as practicable after each of the
conditions set forth in Article VIII of this Agreement and in the Agreement of
Merger have been satisfied or waived, Bancshares will file or cause to be filed
(i) a certificate of merger with the Secretary of State of the State of Ohio,
and

                                       A-2

<PAGE>   122



(ii) a certificate of merger with the Superintendent of the Division of
Financial Institutions, which shall in each case be in the form required by and
executed in accordance with applicable laws and regulations. The Merger shall
become effective at the time the certificate of merger shall be filed with the
Secretary of State of the State of Ohio (the "Effective Time").

     Section 1.2. CONVERSION OF BANK COMMON SHARES INTO BANCSHARES COMMON
     SHARES.

         (a) At the Effective Time, each issued and outstanding share of Bank
("Bank Common Shares"), other than treasury shares (if any) and Bank Common
Shares as to which dissenters' rights have been exercised (collectively,
"Excluded Stock"), thereupon and without further action shall be converted into
and become 13.25 Bancshares common shares, without par value ("Bancshares Common
Shares"). The foregoing conversion of Bank Common Shares into Bancshares Common
Shares shall hereinafter be referred to as the "Share Exchange."

         Notwithstanding the foregoing, in no event shall the holders of Bank
Common Shares receive, in the aggregate, in Bancshares Common Shares with a
Total Value (as hereinafter defined) plus cash in lieu of fractional shares that
is less than 2.7 times the book value of Bank Common Shares on December 31,
1997. In such event, the parties shall adjust the number of Bancshares Common
Shares into which each Bank Common Share shall be converted; provided, however,
solely for purposes of this Section 1.2(a), in the event the book value of Bank
Common Shares shall exceed Two Hundred and Fifty Dollars ($250.00) per share,
Bancshares may elect to terminate this Agreement.

         (b) The term "NMS Closing Price" shall mean the price per share of the
last sale of Bancshares Common Shares reported on the NASDAQ National Market
System at the close of the trading day by the National Association of Securities
Dealers, Inc. The term "Total Value" shall mean the arithmetic mean of the NMS
Closing Prices for the twenty (20) trading days immediately preceding the tenth
trading day, inclusive, immediately preceding the Effective Time.

         (c) No fractional Bancshares Common Share or certificate or scrip
therefor shall be issued as a result of the conversion of Bank Common Shares
into Bancshares Common Shares. To the extent an outstanding Bank Common Share
would otherwise have become a fractional Bancshares Common Share, the holder
thereof shall be entitled to receive a cash payment therefor in accordance with
the provisions of the Agreement of Merger. Such purchases of fractional
interests are merely intended as

                                       A-3

<PAGE>   123



a mechanism for "rounding off" fractional shares and do not constitute
separately bargained for consideration in connection with the transactions
contemplated by this Agreement.

     Section 1.3. EXCHANGE OF CERTIFICATES. After the Effective Time, each
holder of an outstanding certificate or certificates for Bank Common Shares
converted to Bancshares Common Shares shall be entitled to receive a certificate
or certificates representing the number of whole Bancshares Common Shares into
which such holder's Bank Common Shares shall have been converted and, if
applicable, a cash payment in lieu of any fractional share determined in
accordance with the Agreement of Merger. In order to effect such surrender and
exchange, each such holder of Bank Common Shares shall surrender the outstanding
certificate(s) therefor to Bancshares' designated exchange agent (the "Exchange
Agent"), duly endorsed for transfer or accompanied by a duly endorsed assignment
separate from the certificate(s). In the event of a lost certificate, the Bank
shareholder shall provide in lieu of the lost certificate an affidavit and a
bond as required by Bank's Code of Regulations. Pending such surrender and
exchange, such holder's certificate(s) for Bank Common Shares shall be deemed,
for all corporate purposes (other than as set forth in Section 1.4 of this
Agreement), to evidence the number of whole Bancshares Common Shares into which
such Bank Common Shares shall have been converted by the Share Exchange. The
Exchange Agent shall, upon receipt of the duly endorsed Bank certificate or
certificate with a duly endorsed separate assignment, issue the Bancshares'
Common Shares certificate to the surrendering Bank certificate holder, together
with any cash payment in lieu of fractional shares, as applicable.

     Section 1.4. PAYMENT OF DIVIDENDS. Unless and until any such outstanding
certificate(s) for Bank Common Shares shall be so surrendered, no dividend (cash
or stock) payable to holders of record of Bancshares Common Shares as of any
date subsequent to the Effective Time shall be paid to the holder of such
outstanding certificate(s). Upon the surrender of the Bank Common Share
certificate(s), Bancshares shall pay to the record holder of Bancshares Common
Shares issued in exchange therefor, the amount of dividends, if any, but without
interest, that have theretofore become payable to such record holder.

     Section 1.5. CHANGES IN BANCSHARES COMMON SHARES. If, during the interim
period between the date of this Agreement and the Closing Date, the shares of
Bancshares Common Shares shall be

                                       A-4

<PAGE>   124



changed into a different number of shares or a different class or a different
type of security by reason of any reclassification, recapitalization, pro rata
rights offering, subdivision, split, combination or exchange of shares, or if a
stock dividend thereon shall be declared with a record date within such interim
period, the Share Exchange shall be adjusted appropriately to preserve the
aggregate consideration to be exchanged for the Bank Common Shares.

     Section 3.6. TITLE TO ASSETS. Bank has good and marketable title in and to
all of its assets, free and clear of any mortgage, conditional sale agreement,

been well maintained and are in normal operating condition, free from defects
other than normal wear and tear and such minor defects as do not interfere with
the continued use thereof in the conduct of normal operations.

     Section 3.8. CONTRACTS. All contracts and commitments (whether written or
oral) that may have a material effect on the business of Bank are disclosed on
the Disclosure Schedules and copies of any such written contracts or commitments
have been provided to Bancshares. All contracts and commitments for the lease or
purchase of equipment or services have been entered into on an arm's length
basis.

     Section 3.9. INSURANCE OF DEPOSITS. The deposits of Bank are insured by the
Federal Deposit Insurance Corporation in accordance with the Federal Deposit
Insurance Act ("FDIA"). Bank has paid

                                       A-9

<PAGE>   129



all assessments and filed all reports required under the FDIA and is in
compliance with all regulatory requirements imposed in connection with the
insurance of its deposits.

     Section 3.10. LOANS AND INVESTMENTS. The reserves for possible loan losses
on the outstanding loans of Bank, as reflected in the balance sheets of Bank as
of December 31, 1996 (the "1996 Balance Sheet") and as of the Closing Date are,
or will be, as the case may be, adequate to absorb all known and anticipated
loan losses in the loan portfolio of Bank (net of recoveries relating to loans
previously charged off). In addition, the reserves for possible loan losses on
the outstanding loans of Bank, as reflected in the balance sheet of Bank as of
the Closing Date, will be in amount(s) that, as a percentage of the Bank's
loans, are at least equal to the reserves set forth on the 1996 Balance Sheet.
Except as set forth in the Disclosure Schedule, there are no loans of Bank, the
present principal balance of which is in excess of $10,000, that have been
classified orally or in writing by bank examiners (regulatory or internal) as
"Other Loans Specifically Mentioned," "Substandard," "Doubtful," or "Loss," as
of the last examination date (which shall include the date on which any
examination prior to the Effective Time). Each loan in the principal amount of
$2,500 or greater reflected as an asset of Bank in the 1996 Balance Sheet or
acquired by Bank since December 31, 1996, is the legal, valid and binding
obligation of the obligor and any guarantor named therein, and no such loan is
subject to any defense, offset or counterclaim. Except for pledges to secure
public and trust deposits, none of the investments reflected in the 1996 Balance
Sheet under the heading "Investment Securities," and, except as set forth on the
Disclosure Schedule, none of the investments made by Bank since December 31,
1996, is subject to any restriction, whether contractual or statutory, which
impairs the ability of Bank freely to dispose of such investment at any time.
With respect to all repurchase agreements to which Bank is a party, Bank has a
valid, perfected first lien or security interest in the government securities or
other collateral securing the repurchase agreement and the value of the
collateral securing each such repurchase agreement equals or exceeds the amount
of the debt secured by such collateral under such agreement. Except as set forth
in the Disclosure Schedule, and except for transactions aggregating less than
$1,000, Bank has not sold or otherwise disposed of any assets in a transaction
in which the acquirer of such assets or any other person has the right, either
conditionally or absolutely, to require Bank to repurchase or otherwise
re-acquire any such assets.

(i) all certificates of deposit, checking, savings or other deposits in excess
of $25,000 and (ii) all customers with aggregate deposits in excess of $50,000.

     Section 3.12. INSURANCE POLICIES. The Disclosure Schedule contains a list
and a brief description of all insurance policies currently in force with
respect to Bank. All premiums due on such policies have been paid, and such
policies will continue to remain in force through the Effective Time. The
Disclosure Schedule also contains a description of all claims in excess of
$1,000 currently pending under such insurance policies, together with a list of
all other claims in excess of $1,000 which have been filed during the last three
(3) years and a description of the disposition thereof.

     Section 3.13. EMPLOYMENT CONTRACTS AND EMPLOYEE BENEFIT PLANS. The
Disclosure Schedule contains a complete list of each employee contract, bonus,
savings, profit sharing, stock bonus, consulting, pension, retirement,
insurance, severance or any union or collective bargaining agreements or any
contract or agreement with any labor organization and other similar, analogous
or related arrangement or plan, written or oral, including, without limitation,
each "employee benefit plan" within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (all of the
foregoing hereinafter collectively referred to as the "Plans") with respect to
any one or more employees of Bank. To the extent Plans have been reduced to
writing, complete and accurate copies of all such Plans have been delivered to
Bancshares. Each oral Plan, if any, has been accurately described in the
Disclosure Schedule. A complete list (as of August 1, 1997) of all employees of
Bank, their respective dates of hire, cash compensation, compensation pursuant
to participation in each of the Plans and the amount of any indebtedness to Bank
has been delivered to Bancshares. On or before the Closing Date, the Bank shall
fully accrue for all amounts payable under any of the Plans. Bank has also
delivered to Bancshares a list of all employees who are currently entitled to
perquisites (including, but not limited to, automobiles and club memberships) as
well as a

                                      A-11

<PAGE>   131



brief description of each such perquisite. Since the date of such list, no

employees shall earn an hourly wage equal in amount to that wage earned by the
employee immediately prior to the Closing Date; provided, however, that
Bancshares may determine in its sole discretion the number of hours that the
part-time employee shall be scheduled to work.

     All Bank employees who become Citizens Employees shall have their years of

purposes, but not for accrual of benefit purposes, under all Bancshares'
employee pension benefit plans (as defined in Section 3(2) of ERISA), except
with respect to Bancshares' ESOP plan.

     It is understood and agreed that nothing in this Section 4.8 or elsewhere
in this Agreement shall be deemed to be a contract of employment or be construed
to give said employees any rights other than as employees at will under Ohio law
and said employees shall not be deemed to be third-party beneficiaries of this
provision.

     As soon as practicable after the Closing (and provided that the merger of
the account balances in the National City Savings and Investment Plan with
respect to the 16 National City Bank employees hired by Bancshares into the
UniBank Retirement, Savings and Investment Trust shall have been completed),
Bancshares, at its option, shall do one of the following with respect to the
UniBank Retirement, Savings & Investment Plan and Trust ("Savings Plan"):

     (a) Terminate the Savings Plan;

     (b) Freeze the Savings Plan, provided that the cost of plan administration
     shall be borne by each plan participant on a pro rata basis; or (c) Merge
     the Savings Plan assets (after all of the assets have been liquidated,
     including the 880 shares of UniBank stock owned by the Savings Plan) into
     the Citizens Bancshares Profit-Sharing Trust.

or any of its subsidiaries, or any material changes or inaccuracies in data
provided to Bank pursuant to this Agreement.

any and all assets of, or information with respect to, Bank to the end that
Bancshares may have full opportunity to make such investigation, in advance of
the Closing Date, as it shall reasonably desire in order to effectuate the
purposes of this Agreement. To the extent reasonable under the circumstances,
the officers of Bank will confer with the representatives of Bancshares and will
furnish to Bancshares either orally or by means of such records, documents, and
memoranda as are reasonably available or capable of preparation (all of which
Bancshares will be permitted to make copies of) and such other information as
Bancshares may reasonably request.

     Section 5.3. CONSENTS. Bank shall use its best efforts to obtain any
required consents to the transactions contemplated by this Agreement.

with respect to this Agreement and the Agreement of Merger.

     Section 5.8. OTHER OFFERS. On and after the date hereof, except with the
written consent of Bancshares, Bank shall not directly or indirectly solicit or
encourage (nor shall Bank permit any of its officers, directors, employees or
agents directly or indirectly to solicit or encourage), including by way of
furnishing information, any inquiries or proposals for a merger, consolidation,
share exchange or similar transaction involving Bank or for the acquisition of
the shares or all or substantially all of the assets or business of Bank, or
discuss with or enter into conversations with any person, other than Bank
shareholders or employees, concerning any such merger, consolidation, share
exchange, acquisition or other transaction, other than the Share Exchange with
Bancshares. Bank will promptly notify Bancshares orally (to be confirmed in
writing as soon as practicable thereafter) of all of the relevant details
relating to any inquiries or proposals that it may receive relating to any such
matters, including actions it intends to take with respect to such matters.

     In order to induce Bancshares to enter into this Agreement and incur the
substantial expenses involved in effectuating the transactions contemplated
herein, Bank agrees and does hereby promise to pay to Bancshares the sum of
$500,000, upon Bancshares' demand therefor, in the event that the Bank
shareholders fail, within 12 months of the date of this Agreement, to approve
this Agreement or the Agreement of Merger as a result of the decision of the
Bank's Board of Directors to entertain offers from and negotiate with a bona
fide offeree other than Bancshares.

     Section 5.9. DIVIDENDS. On and after the date hereof, Bank shall not
declare, set aside, pay or make any dividend or other distribution or payment
(whether in cash, stock or property) with respect to, or purchase or redeem, any
shares of its capital stock other than (i) regular quarterly cash dividends in
an amount not to exceed the amount paid per share of Bank Common Share for the
same quarter during 1996 and (ii) a special year-end cash dividend in the amount
not to exceed the special year-end cash dividend paid in 1996. It is agreed by
the parties hereto that they will cooperate to assure that as a result of the
Merger, during any quarter, there shall not be a payment of both a Bancshares
and Bank dividend. The parties further agree that if the Closing Date is at the
end of a fiscal quarter, then they will cooperate to assure that the Bank
shareholders receive the dividend, if any, declared by Bank rather than the
dividend for that quarter, if any, declared by Bancshares.

strictest confidence and shall not use, and shall not disclose directly or
indirectly any of such Information except when, after and to the extent such
Information (i) is or becomes generally available to the public other than
through the failure of Bank, Bancshares or Citizens, as the case may be, to
fulfill its obligations hereunder, (ii) was already known to the party receiving
the Information on a nonconfidential basis prior to the disclosure or (iii) is
subsequently disclosed to the party receiving the Information on a

the Share Exchange to be completed on the terms provided in this Agreement and
the Agreement of Merger as soon as reasonably practicable thereafter.

                    REGISTRATION OF BANCSHARES COMMON SHARES
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED
                  --------------------------------------------

     Section 7.1. REGISTRATION STATEMENT. Bancshares and Bank acknowledge that
the transactions contemplated hereby are subject to the provisions of the
Securities Act of 1933, as amended (the "Act") and Rule 145 thereunder.
Bancshares agrees to prepare and file, as soon as practicable after the
execution of this Agreement, a registration statement on Form S-4 (the
"Registration Statement") under and pursuant to the provisions of the Act for
the purposes of registering the Bancshares Common Shares to be issued in
connection with the transactions contemplated hereby. Bank agrees to provide
promptly to Bancshares, information concerning the business and financial
condition and affairs of Bank as may be required or appropriate for inclusion in
the Registration Statement and to cause its counsel and auditors to cooperate
with Bancshares' counsel and auditors in the preparation of such Registration
Statement. Bancshares agrees to use its best efforts to have such Registration
Statement declared

                                      A-27

<PAGE>   147



effective under the Act as soon as may be practicable, and Bank agrees to
distribute the prospectus/proxy statement (to be prepared by and furnished at
Bancshares' expense) contained in such Registration Statement (the
"Prospectus/Proxy Statement") to Bank shareholders not less than ten (10) days
prior to the scheduled meeting of Bank shareholders that will be held to
consider approval of this Agreement and the Agreement of Merger. Except to the
extent permitted by Rule 145(b), Bancshares and Bank agree not to publish any
communication other than the Prospectus/Proxy Statement, in respect of this
Agreement, the Agreement of Merger, or the transactions contemplated therein.
Any communication by either party under Rule 145(b) will be made only upon the
written approval of the other. Bancshares and Bank agree that, between the date
the Registration Statement becomes effective and the Closing Date, they will
keep each other advised on a current basis of material developments concerning
their respective businesses, including any event which would cause the
Prospectus/Proxy Statement to contain an untrue statement of a material fact or
omit to state any material fact necessary to make the statements therein not
misleading. Bancshares shall not be required to maintain the effectiveness of
the Registration Statement for the purpose of resale of Bancshares Common Shares
by Bank shareholders who may be deemed to be affiliates of Bank, as such term is
defined in Rule 145 promulgated under the Act (individually, an "Affiliate" and
collectively, the "Affiliates").

     Section 7.2. AFFILIATES' CERTIFICATES. Each Affiliate of Bank shall furnish
to Bancshares a letter representing that such Affiliate will not sell, assign,
or transfer any of the Bancshares Common Shares received by such Affiliate as a
result of the transactions contemplated by this Agreement, except pursuant to
(a) registration under the Act or (b) a transaction permitted by Rule 145 under
the Act, or (c) a transaction in which, in the opinion of Squire, Sanders &
Dempsey L.L.P. or other counsel satisfactory to Bancshares, or in accordance
with a "no action" letter from the staff of the Securities and Exchange
Commission, the Bancshares Common Shares are not required to be registered under
the Act; and in the event of sale or other disposition pursuant to Rule 145 such
Affiliate will supply satisfactory evidence of compliance with such Rule to
Bancshares. With respect to such representations, each Affiliate shall agree to
hold harmless and indemnify Bancshares and Bancshares' officers and directors
from and against any losses, claims, damages, expenses (including reasonable

                                      A-28

<PAGE>   148



attorneys' fees), or liabilities to which Bancshares or any officer or director
of Bancshares may become subject under the Act or otherwise as a result of the
untruth, breach, or failure of such representations. Each Affiliate shall
further agree that the certificate or certificates representing the Bancshares
Common Shares issued to such Affiliate upon the consummation of the Share
Exchange may bear the following restrictive legend:

         The shares represented by this certificate have been issued or
     transferred to the registered holder as a result of a transaction to which
     Rule 145 under the Securities Act of 1933, as amended (the "Act"), applies.
     The shares represented by this certificate may not be sold, transferred or
     assigned, and the issuer shall not be required to give effect to any
     attempted sale, transfer or assignment, except pursuant to (i) current
     registration under the Act, (ii) a transaction permitted by Rule 145 and as
     to which the issuer has received reasonable and satisfactory evidence of
     compliance with the provisions of Rule 145, or (iii) a transaction in
     which, in the opinion of Squire, Sanders & Dempsey L.L.P. or other counsel
     satisfactory to the issuer or in accordance with a "no action" letter from
     the staff of the Securities and Exchange Commission, such shares are not
     required to be registered under the Act.

     Bancshares covenants and agrees to remove the foregoing restrictive legend
from the certificate or certificates representing the Bancshares Common Shares
issued to an Affiliate and to cancel any stop order instructions with respect
thereto upon receipt of advice from its counsel that such actions are
appropriate under the then-existing circumstances.

     Section 7.3. BLUE SKY REGISTRATION. Bancshares shall, to the extent
required by applicable state securities or "blue sky" laws, as promptly as
practicable after the furnishing by Bank of all information regarding Bank
required or desirable to be reflected therein, file with applicable state
securities or blue sky administrators, and use its best efforts to cause to
become effective or be approved, all registration statements or applications
required to be so filed with respect to the issuance of the Bancshares Common
Shares in connection with the Agreement of Merger.

     Section 7.4.  SUPPLEMENTAL ASSURANCES.

         (a) On the date the Registration Statement becomes effective and on the
Closing Date, Bank shall deliver to Bancshares a certificate signed by its
principal executive officer and its principal financial officer to the effect
that the information contained in the Registration Statement relating to the
business and financial condition and affairs of Bank, does not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading.

relating to the business and financial condition and affairs of Bank) does not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading.

                                   ARTICLE II

                CONVERSION AND EXCHANGE OF UNIBANK COMMON SHARES;
                -------------------------------------------------
                           FRACTIONAL SHARE INTERESTS
                           --------------------------

              2.01  CONVERSION AND EXCHANGE.  At the Effective Time:

                    (a) Each common share of Citizens, without par value, issued
and outstanding immediately prior to the Effective Time shall continue to be one
common share of the Resulting Bank after the Merger.

                    (b) Other than UniBank common shares as to which dissenters'
rights have been exercised, all common shares of UniBank that shall be issued
and outstanding at the Effective Time (the "UniBank Common Shares") shall
thereupon and without further action be converted into and become 13.25
Bancshares common shares having the same rights and privileges as all other
Bancshares Common Shares (individually hereinafter referred to as a "Bancshares
Common Share" and collectively, as the "Bancshares Common Shares").
       
              Notwithstanding the foregoing, in no event shall the holders of
Bank Common Shares receive, in the aggregate, in Bancshares Common Shares with a
Total Value (as hereinafter defined) plus cash in lieu of fractional shares that
is less than 2.7 times the book value of Bank Common Shares on December 31,
1997. In such event, the parties shall adjust the number of Bancshares Common
Shares into which each Bank Common Share shall be converted; provided, however,
solely for purposes of this Section 1.2(a), in the event the book value of Bank
Common Shares shall exceed Two Hundred and Fifty Dollars ($250.00) per shares,
Bancshares may elect to terminate this Agreement.
              
              It is understood and agreed that following the conversion of the
UniBank Common Shares into Bancshares Common Shares, the UniBank Common Shares
will be canceled. 

                    (c) The term "NMS Closing Price" shall mean the price per 
share of the last sale of Bancshares Common Shares reported on the NASDAQ
National Market System at the close of the trading day by the National
Association of Securities Dealers, Inc. The term "Total Value" shall mean the
arithmetic mean of the NMS Closing Prices for the twenty (20) trading days
immediately preceding the tenth trading day, inclusive, immediately preceding
the Effective Time.

                                      A-42

<PAGE>   162



                    (d) Other than as provided for in Section 2.01(b) hereof, at
the Effective Time, all authorized but unissued shares of UniBank Common Shares
shall be canceled and no stock, cash or other property shall be delivered in
exchange therefor.
                    
                    (e) No fractional Bancshares Common Share or certificate or
scrip therefor shall be issued as a result of the conversion of UniBank Common
Shares into Bancshares Common Shares. To the extent an outstanding UniBank
Common Share would otherwise have become a fractional Bancshares Common Share,
the holder thereof shall receive, in lieu thereof, an amount of cash (rounded to
the nearest whole-cent) equal to the product of such fraction multiplied by the
Average NMS Closing Price of Bancshares Common Shares. Such purchases of
fractional interests are merely intended as a mechanism for "rounding off"
fractional shares and do not constitute separately bargained for consideration
in connection with the transactions contemplated by the Plan and by this Merger
Agreement.

                    (f) At the Effective Time, the share transfer books of
UniBank shall be closed and no transfer of UniBank Common Shares shall
thereafter be made or recognized. Notwithstanding any other provision of this
Merger Agreement, neither Bancshares or its agent nor any party hereto shall be
liable to a holder of UniBank Common Shares for any amount properly delivered in

 DISSENTERS' RIGHTS UNDER SECTIONS 1115.19 AND 1701.85 OF THE OHIO REVISED CODE

 DISSENTERS' RIGHTS UNDER SECTIONS 1115.19 AND 1701.85 OF THE OHIO REVISED CODE

1115.19        PAYMENT OF FAIR CASH VALUE OF SHARES TO DISSENTING SHAREHOLDERS

               Unless the articles of incorporation of the state bank otherwise
provide, any shareholder of a state bank that has been consolidated or merged
with, or whose assets have been transferred to, another state or a national
bank, savings bank, or savings association pursuant to provision of this chapter
other than section 1115.15 of the Revised Code, who did not vote in favor of the
consolidation, merger, or transfer, shall be paid the fair cash value, as of the
day before the vote was taken authorizing the action, of the shares held,
excluding from the fair cash value any appreciation or depreciation in
consequence of the consolidation, merger, or transfer which entitled the
shareholder to this relief. Section 1701.85 of the Revised Code shall govern
with respect to the shareholder's rights and any limitations on those rights.
Any shareholder who does not object and demand in writing the payment of the
fair cash value of the shares in the manner and at the time provided in section
1701.85 of the Revised Code, shall be bound by the vote of the board of
directors or the assenting shareholders of the state bank.

1701.85        DISSENTING SHAREHOLDER'S DEMAND FOR FAIR CASH VALUE OF SHARES

               (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, and 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
a 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 twenty

                                       B-2

<PAGE>   168



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 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 within
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.


                                       B-3

<PAGE>   169



               (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 a 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.

               (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.

                                FAIRNESS OPINION
                            AS OF SEPTEMBER 12, 1997
                            ------------------------

         Set forth herein is Danielson Associates Inc.'s ("Danielson
Associates") independent opinion as to the "fairness" of the offer by Citizens
Bancshares, Inc. ("Citizens") of Salineville, Ohio to acquire all of the
outstanding common stock of UniBank (also the "Bank") of Steubenville, Ohio
through an exchange of stock with a value at the time of the offer of about
$52.7 million. The "fair" sale value is defined as the price at which all of the
shares of UniBank's common stock would change hands between a willing seller and
a willing buyer, each having reasonable knowledge of the relevant facts. In
opining to the "fairness" of the offer, it also had to be determined if the
Citizens common stock to be exchanged for UniBank common stock was "fairly"
valued.

         In preparing the opinion, the markets served by UniBank have been
analyzed; its business and prospects have been reviewed; its financial
performance has been compared with banks in the region; and the acquisition
prices of comparable banks have been analyzed. In addition, any unique
characteristics have been considered.

         This opinion is based on data supplied by UniBank, and relies on some
public information, all of which is believed to be reliable, but the accuracy or
the completeness of such information cannot be guaranteed. The opinion assumes
that there are no significant loan problems beyond what is stated in recent
reports to regulatory agencies.

         In determining the "fair" sale value of UniBank, the emphasis has been
on prices paid for banks and bank holding companies with similar financial,
structural and market characteristics. These sale prices were then related to
earnings, assets and equity capital, also referred to as "book."

         In determining the "fairness" of the offer, we compared the common
stock to be exchanged by Citizens for UniBank common stock with the common stock
of other, similar bank holding companies. In so doing, we also compared
Citizens' financial performance with these comparable financial institutions.

         Based on the foregoing, we are of the opinion on the date hereof that
the offer made by Citizens to acquire all of the common stock of UniBank
pursuant to the merger agreement is "fair" from a financial point of view to
UniBank and its shareholders.

                                                 Respectfully submitted,

                                                 Arnold G. Danielson

General

         UniBank is a state-chartered bank that commenced operation in Jefferson
County, Ohio in 1985 in conjunction with the purchase of the Ameritrust
Corporation ("Ameritrust") banking offices in that county. It has ten banking
offices, including the three branches recently acquired from National City
Corporation ("National City"). The Bank is regulated by the Ohio State Banking
Department, and its deposits are insured by the Federal Deposit Insurance
Company ("FDIC").

         The Bank conducts a normal banking business. This includes making
commercial, consumer and real estate loans; providing checking accounts, savings
deposits, and certificates of deposit ("CDs"); and offering safe deposit
services.

Market
- ------

         UniBank's primary market is Jefferson County, which includes the city
of Steubenville. It had seven branches in the county including two in
Steubenville and Toronto and one each in Amsterdam, Winterville and Mingo
Junction prior to acquiring the three National City branches. The three branches
purchased from National City encompass two in Jefferson County, including a
second Mingo Junction office and an office in Tiltonsville. The third National
City branch is in East Liverpool in Columbiana County.

         Jefferson and Columbiana counties, and particularly Jefferson, have
seen better days. In the last census period, 1980 to 1990, Jefferson lost
population at the rate of 1.3% per annum, and its median household income in
1995 of $25,001 was more than $3,500 below the national average.

         The demographics are little better in Columbiana County whose
population of 108,276 in 1990 was about 28,000 more than in Jefferson.
Columbiana had a population outflow in the eighties of .5% per annum and a
median household income of $26,289 in 1995.

         Three other banking organizations - Banc One Corporation ("Banc One"),
Citizens and Trumbull Savings and Loan Association ("Trumbull S&L") - also have
significant positions in Jefferson County. Each had between $120 and $140
million in county deposits in mid-1996 and deposit shares between 13% and 16%.

         Jefferson County has three other banks - Peoples National Bank of Mount
Pleasant ("Peoples"), Steel Valley Bank, N.A. ("Steel Valley") and American
Bancorporation ("American") - that are minor factors. American is a mid-sized
bank headquartered in Wheeling. Peoples and Steel Valley are locally-based.

         In its first full year of operating, 1986, UniBank earned $763,000,
which was a return of .74% and 9.42% on average assets and equity, respectively.
At the end of that year, assets had grown to $108 million.

         Since 1986, UniBank's growth has been slow, but it still almost doubled
its asset base in the ten years prior to its 1997 acquisition of the National
City branches. Its assets passed $150 million in 1993, and by the end of 1996,
it had assets of about $183 million, and with the branch acquisitions, UniBank's
assets should be about $230 million at year-end 1997.

         Except for 1993 when UniBank made a large contribution to reserves, it
has been a good, if not spectacular, earner. It earned $1 million for the first
time in 1987, and by 1995, earnings were approaching $2 million. In 1996, it
surpassed $2 million, and through the first six months of 1997, UniBank's
annualized net income was about $2.3 million, which was 1.15% of average assets
and 13.15% of average equity.

         Until 1995, though, earnings were not at a level that increased capital
as a percent of assets, despite the moderate asset growth. Capital was 7.85% of
assets in 1985, and at year-end 1994, it was 7.88%. The strong earnings in 1995
and 1996, however, pushed capital above 9% of assets, and absent the cash
purchase of the National City branches, capital would be approaching 10% of
assets by year-end 1997.

         UniBank's earnings have been constrained by narrow margins resulting
from a low loan-to-assets relationship without an accompanying below average net
overhead that would be expected from its asset mix. Its net interest income
usually has been only marginally above 4% of average assets, and in the first
quarter of 1997, it dipped to 3.88%. Net overhead, even after the

                                       C-6


<PAGE>   176



virtual elimination of deposit insurance payments in 1996, has been in the
vicinity of 2.25% to 2.30% of average assets.

         With its margin-expense relationship, UniBank would be hardpressed to
produce earnings much in excess of 1% of average assets if it made a normal
contribution to reserves. Its contribution in 1996 was .02% of average assets,
and it made no contribution in the first half of 1997.

         When viewed in the context of eight comparable banks, UniBank had a 44
basis point advantage in its cost of funds in 1997's first quarter, which, when
combined with net overhead that was only seven basis points higher than the
comparable banks, created a favorable variance of 37 basis points in total
expense. This cost advantage, however, was lost in a 79 basis point negative
variance in interest income that was less than 7% of average assets. The end
result was net operating income of 1.65% of average assets that was 42 basis
points below the comparable banks.

         The Bank had a similar interest expense advantage and interest income
disadvantage vis-a-vis Ohio's big banks in the first quarter, and it compounded
the negative variance in net operating income with a net overhead that was 70
basis points higher. This resulted in UniBank's net operating income being
almost a full percentage point lower than the large banks.

         Citizens also is included in the comparisons, and it had interest
expense that was much higher than UniBank and comparative bank averages and net
operating expense that was only slightly less than UniBank and its comparable
banks. It, though, had better net operating income than even the large banks
because of interest income as a percent of average assets that was 192 basis
points higher than UniBank and 123 and 125 basis points, respectively, above the
comparable and large banks.

         The reasons for the income and expense variances between UniBank, the
comparable and large banks and Citizens can be seen in some of the key margin
determinants. They reflect some very different banking patterns.

         UniBank's low yields are partially a result of having only 52% of its
assets committed to loans as of March 31, 1997. The comparable banks are 60%
loaned-out and the large banks 71%. The Bank's average yield on loans in the
first quarter of 1997 was similar to the big banks, but it was 47 basis points
less than the comparable banks.

         On the deposit side, UniBank had an advantage over the comparable and
large banks with transaction deposits and regular savings equalling 55% of its
assets. The comparable banks had these deposits equal to 43% of assets and the
large banks 42%. This contributed to UniBank's low average rate paid on
interest-bearing deposits of 3.68% of average assets, which was 55 basis points
less than the comparable banks and 59 less than the big banks.

         When the loans and deposits are segregated into their major categories,
these differences are accentuated. On both sides of the balance sheet, though,
the difference between UniBank and the others is primarily in a single loan or
deposit type.

         On the loan side, UniBank is roughly equivalent with the comparable and
large bank averages in assets committed to home mortgages, commercial and
industrial loans and consumer loans. Loans secured by commercial real estate,
though, were only 1% of assets as of March 31, 1997 compared to 11% and 12%,
respectively, for the comparable and large banks. This was the primary
difference in the total amount of assets committed to loans between UniBank and
the others, and since they are normally higher yielding loans than most other
types, their lack created a negative variance in loan yield.

         On the deposit side, UniBank's major difference from others is a
greater commitment to interest-bearing checking accounts and regular savings. It
had 47% of its assets supported by this type of deposit compared to 35% for the
comparable banks and 29% for the large banks as of March 31, 1997. This meant
less bought money and a lower cost of funds.

         Citizens is generally similar to the comparable banks in loan and
deposit mix. Its major difference is fewer transaction deposits and greater
dependence on borrowed funds.

         UniBank's asset quality is now exemplary after having struggled in the
mid-nineties. On June 30, 1997, .17% of its assets were not performing. This was
low even by Ohio standards as the percent of assets not performing was .37% and
 .63%, respectively, for the comparable and large banks. As recently as 1994,
though, UniBank had nonperforming assets ("NPAs") in excess of 2% of total
assets.

         Even with such good asset quality UniBank is marginally reserved. As of
June 30, 1997, reserves were .41% of assets and .79% of loans. They also were
247% of nonperforming loans ("NPL"), and are not a cause for real concern, but
UniBank cannot continue to bolster earnings by foregoing contribution to
reserves.

         Until recently, the level of reserves also was mitigated by a
highly-capitalized position. As of December 31, 1996, the Bank's capital was
9.17% of assets and headed toward excess. This was ample protection from a
safety and soundness perspective that could justify a below-average reserve
position, but with the addition of the National City branches, tangible capital
fell to 7.05% of assets as of June 30, 1997. This was still adequate
capitalization, but it was not capital that would justify marginal reserves.

         What do all of these numbers mean? They depict a solid, but slightly
underperforming, small-town Midwest bank. It has never reached the earnings
level of similar Midwest banks despite a very good deposit base, and in the most
recent years, UniBank's net income has looked a little better than it really was
because of minimal, if any, contributions to reserves. The problems are too few
loans and an above-average net overhead. Also complicating future earnings gains
is that increasing loans as a percent of assets would require large increases to
reserves and put upward pressure on overhead.


                                      C-10


<PAGE>   180



         From an acquisition perspective, though, these problems are not likely
to be major concerns. A buyer will view the cheap deposits as a big plus and is
likely to assume that it can improve the loan relationship, and hence margins,
without increasing overhead. The biggest buyer negative would be the need to
bring reserves to a level consistent with its own.


                               ACQUISITION PRICING
                               -------------------

         The "fair" sale value of UniBank, or any banking organization, is
usually determined by the marketplace through the prices being paid for similar
banks or bank holding companies. Since no two banks are exactly the same,
though, there are always comparability problems. Valuations also can be
complicated by either a sudden change in economic or market conditions or by
limited acquisition activity.

         The sharp decline in stock prices in late 1987 and deterioration of
asset quality in the early nineties are examples of events that radically
changed bank acquisition pricing. In each case, the stock prices of large
acquirers were adversely impacted, and their ability to pay up to the sellers'
expectations was constrained.

         Another method of valuation, and an important form of measurement when
there are few applicable comparisons, is to calculate the value based on
discounted future earnings or dividends. This best indicates what a buyer can
afford when paying cash rather than exchanging a stock that has a value well in
excess of book, but it is a benchmark for stock transactions as well. Like all
statistical projections, though, discounting future earnings or dividends is
only as accurate as the assumptions used, and they can result in prices
significantly different than the realities of the marketplace.

Regional Bank Pricing
- ---------------------

         Bank acquisition pricing in Ohio and neighboring states has been very
cyclical and has followed the market relative to the pricing of bank stocks.
When bank stocks traded at high multiples of earnings and book, then the prices
paid for banks also were high.

         Thus, when bank stocks were at record levels in 1987, acquisition
prices peaked in UniBank's extended region - Kentucky, Maryland, Ohio, West
Virginia and Pennsylvania - with a median price of 252% of book and 15.9 times
earnings for banks with assets in excess of $100 million. When bank stocks went
out of favor after 1987, acquisition pricing drifted down to median offers of
154% of book and 12 times earnings by 1991.

         Since that low point, bank acquisition prices have moved up steadily,
and the median went above 190% of book and 17 times earnings in 1993. Pricing
was fairly steady relative to book from 1993 through 1996, but the multiples of
earnings paid climbed, albeit erratically, to 20 times earnings in 1996. In
1997, pricing continued to rise with the median value being almost 23 times
earnings and 297% of book.

         The median price times earnings of bank sales nationwide for acquirees
with assets between $100 million and $5 billion in 1997, except California,
which has its own dynamics because of its late emergence from the recession, has
increased in every month. The increases between late spring and July were
particularly large relative to both earnings and book.

         After modest gains from January through April when the median price
times earnings was below 1996 levels, the median price rose to 17.8 times
earnings in May, in June it was 21 times earnings, and by July, it was 21.9
times earnings. Corresponding percentages of book in those three months were
222%, 247% and 265%. In August, the median prices paid for a bank of this size
were 20.7 times earnings and 268% of book.

         Changes in acquisition pricing usually reflect the stock prices of the
acquirers, and this relationship can be seen in 1997. From January through
April, the median bank stock price as a multiple of earnings was generally
between 14 and 15 times earnings. In May, the national median bank stock was
selling at 15.2 times earnings. In June, it was 16.2 times earnings, and by
July, the median had reached 17 times earnings before dipping slightly in
August.

         The most applicable recent transactions to the sale value of UniBank
were Fulton Financial Corporation ("Fulton") buying Keystone Heritage Group,
Inc. ("Keystone Heritage"); Area Bancshares Corporation's ("Area") purchase of
Cardinal Bancshares, Inc. ("Cardinal") in 1997; and a 1996 West Virginia
transaction, Horizon Bancorp, Inc. ("Horizon") buying Twentieth Bancorp, Inc.
("Twentieth"). Two of these acquirees received more than 20 times earnings, and
Keystone Heritage was paid over 300% of book. Not every bank gets that high a
price, though, as Cardinal was paid only 16.9 times earnings and 188% of book.

         These and other deals would suggest the present sale value of quality
banks of UniBank's size is at least 20 to 22 times earnings and 230% to 270% of
book. Applying the mid-points to UniBank results in an unadjusted sale value of
$45.7 million, or $610 per share, based on earnings and $44.4 million, or $593
per share, using book value.

         It is earnings, though, and not book that will determine the price.
Thus, the most meaningful comparison for UniBank is the $45.7 million, or $610
per share, which is 257% of book.

Investment Valuation
- --------------------

         Since acquisitions based on comparable sale prices include a number of
variables such as the acquirer's stock price, capital of the acquiree, asset
quality and the condition of the equity markets, they may not reflect the true
long-term value to the acquirer. Thus, sale valuations also should consider the
value based on the expected return on the investment absent the benefit of a
stock with a high multiple. Two of the most widely used methods for doing this
are discounted future earnings and dividends.

         In applying discounted future earnings to UniBank, several variables
were used relative to growth, earnings and acceptable returns on investments.
Annual asset growth was calculated at 6%; the return on average assets at 1.20%,
1.10% and 1.00%; and the discount rates utilized were 11%, 13% and 15%.

         The discount rate is an approximate equivalent to the return desired on
the initial investment. In other words, a discount rate of 13% is about a 13%
return on the initial investment.

         UniBank has had modest growth recently, and earnings have been in the
vicinity of 1.15% of average assets range. A 6% asset growth should be
sustainable, but the need to make more normal contributions to reserve could
push earnings in the next couple of years into the 1% to 1.10% range unless
there are significant positive changes elsewhere.

         Using a 6% rate of asset growth and a 1.10% return on average assets,
which approximates expectations with a normal contribution to reserves, the
investment value at a discount rate of 13% is $32.1 million. At an 11% discount
rate, the investment value would be $39.5 million. These values translate into
187% and 230% of book, respectively. In our analysis, we have determined these
are the appropriate discount rates in this environment for large bank
acquisitions. This projection, however, determines value based on a stand-alone
basis and has not factored in the cost savings of a merger.

         Similar in approach to discounted future earnings is discounted
dividend analysis, which discounts dividends to shareholders based on the
theoretical approach that it is cash put into the hands of shareholders that
really counts. This approach assumes that all excess earnings are returned to
the shareholders as dividends for a set period of time and then the shares are
sold at market value.

         The key difference between this approach and discounted future earnings

future earnings.

a 15% cost savings phased in over a two year period, 12 times earnings terminal
value at the end of five years and a 13% discount rate produced a sale value for
UniBank of $38.2 million. At an 11% discount rate and 14 times earnings terminal
value, UniBank's value is approximately $46.2 million.

Summary
- -------

         Recent acquisition pricing suggests the "fair" value for normal banks
in Ohio is at least 20 to 22 times earnings, which is higher than the value
produced by investment calculations. How this translates into book value is
determined by the return on equity of the acquired institutions, but the most
recent offers have been above 250% of book.


                            MARKET VALUE ADJUSTMENTS
                            ------------------------

         To determine the "fair" sale value of UniBank, it is necessary to
consider how it differs from other banks and bank holding companies that were
sold recently, and then make adjustments based on the differences, if any. Some
areas that should be considered are profitability, capital, growth, size,
market, asset mix, asset quality, deposit mix and management. Also, if there are
any unique circumstances, they also should be considered.

Profitability
- -------------

         Earnings are the primary determinant of sale value and have been used
to determine UniBank's "fair" value, but relationships based on earnings also
have to consider their sustainability. Assuming UniBank can get some improvement
in either loans as a percent of assets or net overhead to offset it again making
more normal contributions to reserves, which should be doable, it is likely that
the present level of earnings as a percent of assets could be maintained. Since
net income was used to determine UniBank's "fair" sale value and is a fair
representation of future earning power, no change in value is needed based on
profitability.

Capitalization
- --------------

         UniBank is adequately-capitalized, even after the branch acquisitions,
and is not being close to "excess," as is the case with so many small and
mid-size banks, which is a plus. Normal capital, though, does not effect an
earnings-derived value, and, as a result, no adjustment is merited based on
capital.

Growth Momentum
- ---------------

         In recent years, UniBank's assets have been growing at about 5% to 6%
per annum, which is good, but not spectacular, and this growth reflects the
markets being served. This modest growth is typical of small Midwest banks, in
general, and, as a result, the growth on its own is not a cause for a value
adjustment.

Size
- ----

         The comparable bank acquisitions take into account UniBank's size. As a
result, size is not a reason for a value adjustment.

Market
- ------

         The market served, which is primarily Jefferson County, is a low growth
area, but it also offers minimal asset quality risk. This, however, is the case
with most markets in the east central part of the country and is not a cause for
a downward value adjustment.

                                      C-16


<PAGE>   186




Asset Mix And Quality
- ---------------------

         UniBank is underloaned for a bank its size, but it has good asset
quality. The lower than normal loan-to-asset ratio, though, is a major
determinant of profitability and is included in a profit-derived price. The
asset quality, albeit excellent, also is no longer a major differentiating
factor between banks. Thus, there is no reason for value adjustments relative to
asset quality or mix.

Deposit Mix
- -----------

         UniBank's strong point is its deposit mix, but deposits also are a
major ingredient in profitability and, as such, are already impacting a value
that is earnings-driven. As a result, deposits do not merit a value adjustment.

Management
- ----------

         Since UniBank is a fair performer, and has been so for a long time, its
management is adequate. Management, though, would not be a major concern to a
buyer as large as Citizens, and, thus, management does not merit a value
adjustment on its own.

Unique Considerations
- ---------------------

         UniBank is a fairly typical small-town Midwest bank, and it has no
unique characteristics.

Conclusion
- ----------

         When the various components of UniBank's sale value are considered, it
is generally similar to other banks of its size. If there is a difference, it is
in earnings, and earnings are reflected in valuation. Thus, there is no cause
for adjusting the "fair" value of UniBank relative to a normal profit-driven
value.

                                    --------

The Offer
- ---------

         Citizens has offered to acquire UniBank by exchanging 13.25 shares of
Citizens common stock for each share of UniBank's common stock outstanding. This
offer had a monetary value of $52.7 million as of September 12, 1997.

Description Of Acquirer
- -----------------------

         Citizens is a multi-bank holding company headquartered in Salineville,
Ohio. It has two bank subsidiaries, The Citizens Banking Company ("Citizens
Banking"), which includes all of its Ohio banking offices, and First National
Bank of Chester ("First Chester") in West Virginia. Its other subsidiaries are
Freedom Financial Insurance Company and Freedom Express, Inc.

         The primary banking affiliate is Citizens Banking, which has 27 of its
28 banking offices, and it began operating in 1902. It is regulated by the Ohio
State Bank Department, and its deposits are insured by the FDIC.

         Citizens moved into West Virginia on January 1, 1990 by acquiring First
Chester in an exchange of stock valued at $2.7 million. This was about 139% of
First Chester's book value.

         In its largest acquisition to date, Citizens in September 1990 acquired
from the Resolution Trust Company ("RTC") certain assets and assumed certain
deposits and liabilities of the failed Midland

                                      C-17


<PAGE>   187



Buckeye Federal Savings and Loan ("Midland Buckeye") of Alliance, Ohio. The
deposits acquired were about $145 million. Citizens subsequently sold two of the
Midland Buckeye branches with combined deposits of $16 million.

         In October 1990, Citizens consummated a second transaction with the RTC
whereby it purchased certain assets and assumed the deposits of a branch of
Union Federal Savings Bank ("Union Federal"). At the time of acquisition, the
branch had deposits of $20 million. It was located in Leetonia, Ohio.

         In 1994, Citizens acquired two small banks. The first was the Firestone
Bank ("Firestone") in Lisbon, Ohio that merged with Citizens in an exchange of
stock valued at $6.9 million, which was 169% of book. The second was Unity
Bancorp ("Unity") and its affiliate, New Waterford Bank ("New Waterford"), of
New Waterford, Ohio that was acquired in an exchange of stock valued at $5
million, which was 107% of book. Each was merged into Citizens Banking.

         In 1996, Citizens acquired Western Reserve Bank ("Western Reserve") of
Lowellville, Ohio and the Navarre Deposit Bank Company ("Navarre Deposit") of
Navarre, Ohio. The Western Reserve acquisition was an exchange of stock valued
at $10.8 million, or 222% of book. The Navarre Deposit acquisition was
accomplished through an exchange of stock valued at $15.6 million, or 221% of
book.

         On June 10, 1997, Citizens announced the purchase of three Belmont
County, Ohio branches of F.N.B. Corp. ("F.N.B."). These branches had deposits of
about $66 million at the time of the announcement.

         The branches acquired as well as those of Firestone, New Waterford,
Western Reserve and Navarre Deposit are being operated as offices of Citizens.
First Chester has operated independently because of the interstate banking
regulations, but this will change in the future.

Market
- ------

         Citizens' principal subsidiary, Citizens Banking, is headquartered in
Salineville, Ohio, which is in Columbiana County, but it is also very close to
the Jefferson County line. More than 50% of Citizens' deposits are in these two
counties. The large deposit share in Columbiana County is due in part to the
purchase of failed thrift deposits.

         Citizens is a marginal factor in Stark and Mahoning counties, two large
counties to the north. It does not have branches in these counties' major
business centers, Canton and Youngstown.

         In Carroll County, Citizens has a single branch located in the largest
city, Carrollton, that holds 30% of the county deposits. Carroll, however, is a
small, rural county with a limited deposit base.

         It recently entered Belmont County via the branch purchases from F.N.B.
The $70 million in deposits these branches held in mid-1996 represented about a
7.2% share.

         First Chester has a single branch in Hancock County. This ranks it
fourth in size, but it is still a marginal factor with less than 4% of the
county's deposits.

         The overall market has been economically stagnant for years, and two
counties from which Citizens derives over 50% of its business have the lowest
per household incomes in the immediate region. Of the six Ohio and one West
Virginia counties in which Citizens is present, only Carroll gained population
during the eighties. Columbiana, Stark and Jefferson counties had population
declines of .5%, .3% and 1.3% per annum, respectively.

Financial Performance
- ---------------------

         Citizens has been an exceptional financial performer. In less than ten
years, it has increased assets more than four-fold to a little over $1 billion,
and it has had a return on average equity in excess of 16% in each of those
years. Only in 1991 did its return on average assets fall below 1.22% of average
assets, and then it was still a respectable 1.00%; and in that year, it was
absorbing a major thrift acquisition.

         Its performance in the last three years has been particularly
impressive. Through 1995, 1996 and the first half of 1997, Citizens had average
returns on average assets and equity of 1.64% and 18.46%, respectively. In the

         Citizens' rapid growth and the Midland-Buckeye cash purchase had kept
the strong earnings from creating excess capitalization. After buying
Midland-Buckeye from the RTC, its capital was reduced below 5% of assets, and
even though growing rapidly as a percent of assets after that, capital did not
go above 7% of assets until 1994. By the end of 1995, though, capital was
nearing 9% of assets, and it went above 9% in 1996. Capital fell somewhat in the
first half of 1997 as Citizens leveraged its asset base, but tangible capital
was still almost 9% of assets.

         Citizens' good earnings were historically a product of wide margins
that were primarily yield-driven. Net interest income has been above 4.50% of
average assets since 1990, and had increased every year after 1990 until it
reached 5.00% in 1995. In 1996, it dipped slightly to 4.87% of average assets,
but this still was a very wide margin.

         These margins were enough to cover net operating expense that was
generally in the 2.40% to 2.60% of average assets range in the early nineties
and still produce good earnings. It was when net overhead, helped by the
industry-wide reduction in deposit insurance costs, fell to 2.35% of average
assets in 1995 and then 2.03% in 1996 that its return on average assets was able
to climb to very high levels.

         Citizens' leveraging in 1997 was reflected in sharp declines in both
net interest income and net operating expense. In the first half of the year,
net operating expense fell to 4.32% of average assets, or 55 basis points below
1996. Meanwhile net overhead declined to 1.59% of average assets, which was 44
basis points below 1996. The net result, though, was virtually no change in net
income as a percent of average assets.

Stock Performance
- -----------------

         Citizens' strong financial performance has been reflected in a stock
price that as of September 12, 1997 was trading at a price of $53 per share.
This was a very high 20.1 times earnings and 330% of book.

         Since 1990, the pricing of Citizens stock has gone through three
distinct phases. From 1990 to 1992, it was an unlisted stock that was selling
between 8 and 9 times earnings and usually below 150% of book. During this
period, the price rose from a little over $8 per share to almost $12. Then from
1993 through 1996, with the stock listed on a national exchange, its price was
usually in the 13 to 14 times earnings and 200% to 220% of book range. During
this period the stock rose from that almost $12 per share at the end of 1992 to
a little over $33 at the end of 1996. The third period is 1997 with the $53
price and very high multiples of earnings and book.

         Citizens has had low dividend yields during the nineties as it
concentrated on growth and rewarding shareholders through tangible capital per
share and stock price appreciation. Prior to 1996, the dividend yield was less
than 2% even though the stock price was quite low during some of these years. In
1996, the dividend was increased substantially, and the yield based on the
year-end stock price was 2.55%. The almost 60% increase in the stock price since
then has lowered the yield to about 2%.

                Financial Performance and Stock Price Comparison
                ------------------------------------------------

         To determine the "fair" value of the Citizens common stock to be
exchanged for the common stock of UniBank, Citizens has been compared to eleven
publicly-traded bank holding companies ("comparable banks" or the "comparative
group"). These comparable banks have assets in the $500 million to $3 billion
range and have no extraordinary characteristics.

         When Citizens' financial performance is compared with these banks as of
June 30, 1997, or the twelve months ending that date, it is superior in every
criteria, and in most cases, far superior. Its returns on average assets and
equity of 1.70% and 18.18%, respectively, are more than one-third higher than
the comparative group medians, and only one of the comparable banks, Park
National, had a higher return on equity. These high returns were solidly-based
with net operating income at 2.73% of average assets, which was substantially
higher than comparable bank median of 2.07%.

         The only area in which Citizens was not far superior to the comparative
group median was tangible capital as a percent of assets. With capital at 8.94%
of assets in mid-1997, it was marginally higher and trending toward excess
capitalization, but with an 18.18% return on equity, its capital is being well
utilized.

         Asset quality also was a strong point for Citizens. With only .41% of
its assets not performing, it was significantly below the comparable bank median
of .59%.

         Citizens' strong financial performance is reflected in its stock price.
As of September 12, 1997, its stock was trading at 20.1 times earnings and 330%
of book. These were both above the comparative group medians, although the
multiple of earnings, which normally is the primary determinant of value, was
only slightly higher.

         When a bank has a high return on equity, a modest favorable variance in
the multiple of earnings will result in a large advantage in the price as a
percent of book. In Citizens' case, a 20.1 earnings multiple translated into a
price of 330% of book. This was substantially higher than the 244% comparative
group median.

         Citizens does not pay as much of its earnings out in dividends as these
other banks - i.e., a 37% payout ratio compared to a 47% median - and this is
reflected in a lower dividend yield. Its dividend as of September 12, 1997 was
2.00% compared to a 2.57% comparative group median. A lower dividend yield,
though, often reflects a higher growth situation, which is true of Citizens.
When its dividend is added to its annual increase in tangible capital per share,
it has delivered a gain of more than 18% annually to its shareholders since
1990.

         Its stock also has a relatively high degree of liquidity. The average
shares traded weekly over the last three months was .58% of total shares
outstanding. Only one of the comparable banks, United, did better, and the
comparative group median was .24%.

         From an overall perspective, Citizens' financial performance merits a
premium over the comparable bank median stock price, and the only "pull" in the
other direction is a low dividend, which is to be expected considering the rapid
rate of growth. How much of a premium it deserves, though, is a moot point
relative to the "fairness" of its stock price since it is trading within the
normal range of the comparative group, albeit on the high end. Thus, Citizens'
stock is "fairly" priced.

Dilution Impact
- ---------------

         Since Citizens is paying a higher multiple of earnings for UniBank than
the stock being exchanged is selling at relative to its own earnings, it will be
absorbing some earnings dilution as part of this acquisition. It is almost
always a plus for a seller to get the highest price, but there is a point at
which a high price can have such a negative impact relative to earnings per
share ("EPS") dilution for the buyer that the stock the seller receives could be
devalued.

</TABLE>

         The EPS dilution in this case is not large, and should not negatively
impact Citizens' stock price. Based on data for the twelve months ending June
30, 1997, Citizens' earnings per share will decline by $.06, or 2.4% as a result
of acquiring UniBank. This is below the 5% to 6% that is often considered the
upper limit for a substantial acquisition, and UniBank is a substantial
acquisition. This dilution also should be recoverable through cost savings
within a year making the acquisition accretive to Citizens' EPS in 1999.

         The dilution in Citizens' capital per share ("CPS") is accretive. Based
on June 30, 1997 capital, the CPS accretion was $.03, or .2%.


                                    VALUATION
                                    ---------

         There are numerous methodologies for determining the "fair" sale value
of a bank or bank holding company. These include a) the "sale" prices of similar
institutions, b) return on investment calculations with specific growth and
earnings assumptions, c) premiums over a "fair" stock price and d) the
liquidation value.

         The recent sale prices of similar institutions is the most commonly
used methodology when there are sufficient comparisons as it, in effect, lets
the market determine the "fair" sale value. This approach normally assumes an
exchange of stock, and when acquirer stock prices are high, the reported sale
prices may exceed "fair" investment value calculations.

         Using the "sale" prices of other banks is the preferred method in this
instance. It is dictated by the current acquisition environment, which has been
dominated by transactions involving an exchange of stock.

         The best measurement tool is earnings if they are normal or can be
normalized, and they are the primary determinant of "fair" sale value. Since
UniBank's earnings have been consistent in recent years, earnings clearly are
the best determinant of its "fair" sale value. Book and asset value are only
used as a value determinant when earnings are not meaningful. Values quoted as a
percent of book are the result of the book relationship to earnings.


                                      C-25


<PAGE>   195



         In determining the "fair" sale value of UniBank, the key factor is the
acquisition prices in 1997 for banks in its region with assets in excess of $100
million. There were seven such acquisitions, with a median price of 22.6 times
earnings and 297% of book.

         Also playing a major role in determining the "fair" value are the three
most applicable acquisitions. One of them, Horizon buying Twentieth was in 1996,
but was in a similar Ohio Valley market and was priced at 22.6 times earnings
and 247% of book. The other two, Fulton acquiring Keystone Heritage and Area
buying Cardinal, were outside of the Ohio Valley, but were in 1997 and within
UniBank's extended region. These mergers reflect the most recent acquisition
dynamics and were priced at 16.9 and 20.8 times earnings.

         Using investment calculations, discounted future earnings and
dividends, to determine UniBank's sale value, we feel the proper discount rate
is 13%, which creates values ranging from 14.7 to 17.5 times earnings. This
translated into 187% to 215% of book.

         Based on the comparable transactions primarily, but also the investment
calculations, the "fair" sale value for UniBank, absent adjustments, is 20 to 22
times earnings, or $43.6 to $47.9 million. This is $581 to $639 per share and
equates to 245% to 269% of book. The mid-point is a $45.7 million or $610 per
share.

         The offer by Citizens of $52.7 million, or $703 per share, is a) well
above the unadjusted "fair" value, b) should result in accretion to Citizens'
earnings as early as 1999, and c) the Citizens' stock to

financial point of view to UniBank and its shareholders.

                 PART II INFORMATION NOT REQUIRED IN PROSPECTUS

               ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS

         Section 1701.13(E) of the Ohio Revised Code grants corporations broad
powers to indemnify directors, officers, employees and agents. Section
1701.13(E) provides:

                  (E)(1) A corporation may indemnify or agree to 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 corporation, by reason of the fact
         that he is or was a director, officer, employee, or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee, member, manager, or agent of
         another corporation, domestic or foreign, nonprofit or for profit, a
         limited liability company, or a partnership, joint venture, trust, 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
         corporation, and, with respect to any criminal action or proceeding, if
         he 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, 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 corporation, and, with
         respect to any criminal action or proceeding, he had reasonable cause
         to believe that his conduct was unlawful.

                  (2) A corporation may indemnify or agree to indemnify any
         person who was or is a party, or is threatened to be made a party, to
         any threatened, pending, or completed action or suit by or in the right
         of the corporation to procure a judgment in its favor, by reason of the
         fact that he is or was a director, officer, employee, or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee, member, manager, or agent of
         another corporation, domestic or foreign, nonprofit or for profit, a
         limited liability company, or a partnership, joint venture, trust, or
         other enterprise, against expenses, including attorney's fees, actually
         and reasonably incurred by him in connection with the defense or
         settlement of such action or suit, 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 corporation, except that no indemnification shall be
         made in respect of any of the following:

                  (a) Any claim, issue, or matter as to which such person is
         adjudged to be liable for negligence or misconduct in the performance
         of his duty to the corporation unless, and only to the extent that, the
         court of common pleas or the court in which such action or suit was
         brought determines, upon application, that, despite the adjudication of
         liability, but in view of all the circumstances of the case, such
         person is fairly and reasonably entitled to indemnity for such expenses
         as the court of common pleas or such other court shall deem proper;

                  (b) Any action or suit in which the only liability asserted
         against a director is pursuant to section 1701.95 of the Revised Code.

                  (3) To the extent that a director, trustee, officer, employee,
         member, manager, or agent has been successful on the merits or
         otherwise in defense of any action, suit, or proceeding referred to in
         division (E)(1) or (2) of this section, or in defense of any claim,
         issue, or matter therein, he shall be indemnified against expenses,
         including attorney's fees, actually and reasonably incurred by him in
         connection with the action, suit, or proceeding.

<PAGE>   198



                  (4) Any indemnification under division (E)(1) or (2) of this
         section, unless ordered by a court, shall be made by the corporation
         only as authorized in the specific case, upon a determination that
         indemnification of the director, trustee, officer, employee, member,
         manager, or agent is proper in the circumstances because he has met the
         applicable standard of conduct set forth in division (E)(1) or (2) of
         this section. Such determination shall be made as follows:

                  (a) By a majority vote of a quorum consisting of directors of
         the indemnifying corporation who were not and are not parties to or
         threatened with the action, suit, or proceeding referred to in division
         (E)(1) or (2) of this section;

                  (b) If the quorum described in division (E)(4)(a) of this
         section is not obtainable or if a majority vote of a quorum of
         disinterested directors so directs, in a written opinion by independent
         legal counsel other than an attorney, or a firm having associated with
         it an attorney, who has been retained by or who has performed services
         for the corporation or any person to be indemnified within the past
         five years;

                  (c) By the shareholders;

                  (d) By the court of common pleas or the court in which the
         action, suit, or proceeding referred to in division (E)(1) or (2) of
         this section was brought.

                  Any determination made by the disinterested directors under
         division (E)(4)(a) or by independent legal counsel under division
         (E)(4)(b) of this section shall be promptly communicated to the person
         who threatened or brought the action or suit by or in the right of the
         corporation under division (E)(2) of this section, and, within ten days
         after receipt of such notification, such person shall have the right to
         petition the court of common pleas or the court in which such action or
         suit was brought to review the reasonableness of such determination.

                  (5)(a) Unless at the time of a director's act or omission that
         is the subject of an action, suit, or proceeding referred to in
         division (E)(1) or (2) of this section, the articles or the regulations
         of a corporation state, by specific reference to this division, that
         the provisions of this division do not apply to the corporation and
         unless the only liability asserted against a director in an action,
         suit, or proceeding referred to in division (E)(1) or (2) of this
         section is pursuant to section 1701.95 of the Revised Code, expenses,
         including attorney's fees, incurred by a director in defending the
         action, suit, or proceeding shall be paid by the corporation as they
         are incurred, in advance of the final disposition of the action, suit,
         or proceeding upon receipt of an undertaking by or on behalf of the
         director in which he agrees to do both of the following:

                  (i) Repay such amount if it is proved by clear and convincing
         evidence in a court of competent jurisdiction that his action or
         failure to act involved an act or omission undertaken with deliberate
         intent to cause injury to the corporation or undertaken with reckless
         disregard for the best interests of the corporation;

                  (ii) Reasonably cooperate with the corporation concerning the
         action, suit, or proceeding.

                  (b) Expenses, including attorney's fees, incurred by a
         director, trustee, officer, employee, member, manager, or agent in
         defending any action, suit, or proceeding referred to in division
         (E)(1) or (2) of this section, may be paid by the corporation as they
         are incurred, in advance of the final disposition of the action, suit,
         or proceeding, as authorized by the directors in the specific case,
         upon receipt of an undertaking by or on behalf of the director,
         trustee, officer, employee, member, manager, or agent to repay such
         amount, if it ultimately is determined that he is not entitled to be
         indemnified by the corporation.

<PAGE>   199



                  (6) The indemnification authorized by this section shall not
         be exclusive of, and shall be in addition to, any other rights granted
         to those seeking indemnification under the articles, the regulations,
         any agreement, a vote of shareholders or disinterested directors, or
         otherwise, both as to action in their official capacities and as to
         action in another capacity while holding their offices or positions,
         and shall continue as to a person who has ceased to be a director,
         trustee, officer, employee, member, manager, or agent and shall inure
         to the benefit of the heirs, executors, and administrators of such a
         person.

                  (7) A corporation may purchase and maintain insurance or
         furnish similar protection, including, but not limited to, trust funds,
         letters of credit, or self-insurance, on behalf of or for any person
         who is or was a director, officer, employee, or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, trustee, officer, employee, member, manager, or agent of
         another corporation, domestic or foreign, nonprofit or for profit, a
         limited liability company, or a partnership, joint venture, trust, or
         other enterprise, against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the corporation would have the power to indemnify
         him against such liability under this section. Insurance may be
         purchased from or maintained with a person in which the corporation has
         a financial interest.

                  (8) The authority of a corporation to indemnify persons
         pursuant to division (E)(1) or (2) of this section does not limit the
         payment of expenses as they are incurred, indemnification, insurance,
         or other protection that may be provided pursuant to divisions (E)(5),
         (6), and (7) of this section. Divisions (E)(1) and (2) of this section
         do not create any obligation to repay or return payments made by the
         corporation pursuant to division (E)(5), (6), or (7).

                  (9) As used in division (E) of this section, "corporation"
         includes all constituent entities in a consolidation or merger and the
         new or surviving corporation, so that any person who is or was a
         director, officer, employee, trustee, member, manager, or agent of such
         a constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee, member,
         manager, or agent of another corporation, domestic or foreign,
         nonprofit or for profit, a limited liability company, or a partnership,
         joint venture, trust, or other enterprise, shall stand in the same
         position under this section with respect to the new or surviving
         corporation as he would if he had served the new or surviving
         corporation in the same capacity.

         Section 33 of the Regulations of Citizens Bancshares, Inc. states as
follows:

         Section 33. INDEMNIFICATION. The Corporation shall indemnify any
director or officer and any former director or officer of the Corporation and
any such director or officer who is or has served at the request of the
Corporation as a director, officer or trustee of another corporation,
partnership, joint venture, trust or other enterprise (and his heirs, executors
and administrators) against expenses, including attorney's fees, judgments,
fines and amounts paid in settlement, actually and reasonably incurred by him by
reason of the fact that he is or was such director, officer or trustee in
connection with any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative to the full extent
permitted by applicable law. The indemnification provided for herein shall not
be deemed to restrict the power of the Corporation (i) to indemnify employees,
agents and others to the extent not prohibited by law, (ii) to purchase and
maintain insurance or furnish similar protection on behalf of or for any person
who is or was a director, officer or employee of the Corporation, or any person
who is or was serving at the request of the Corporation as a director, officer,
trustee, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise against any liability asserted against him or incurred
by him in any such capacity or arising out of his status as such, and (iii) to
enter into agreements with persons of the class identified in clause (ii) above
indemnifying them against any and all liabilities (or such lesser
indemnification as may be provided in such agreements) asserted against or
incurred by them in such capacities.

                                       S-3

<PAGE>   200




         In addition, Bancshares has entered into indemnification agreements
with each of its directors and executive officers which expand the indemnitees'
rights in the event that Ohio law and Bancshares' Regulations are further
changed. Pursuant to the agreements, indemnitees receive the highest available
of the following: (i) the benefits provided by Bancshares' Regulations as of the
date of the agreement; (ii) the benefits provided by Bancshares' Regulations in
effect at the time that indemnification expenses are incurred; (iii) the
benefits allowable under Ohio law which is in effect on the date of the
agreement; (iv) the benefits allowable under the law of the jurisdiction under
which Bancshares exists at the time indemnifiable expenses are incurred; (v) the
benefits available under liability insurance obtained by Bancshares; (vi) the
benefits which would have been available to the indemnitee under a Bancshares
insurance policy which was in effect prior to and expired on May 8, 1986; or
(vii) such other benefits are or may be otherwise available to the indemnitee.
The indemnification rights available under the agreements are subject to certain
exclusions, including a provision that no indemnification shall be made if a
court determines by clear and convincing evidence that the indemnitee has acted
or failed to act with deliberate intent to cause injury to, or with reckless
disregard for the best interests of, Bancshares.

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 to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim information.

         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 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 Act
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
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act 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 Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail

                                       S-6

<PAGE>   203



or other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of 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.

Citizens Bancshares, Inc.
10 East Main Street
Salineville, Ohio  43945


          RE:     CITIZENS BANCSHARES, INC./UNIBANK


Ladies and Gentlemen:

          We have acted as counsel for Citizens Bancshares, Inc., an Ohio
corporation (the "Corporation") in connection with a Registration Statement on
Form S-4 (Registration No. ________________) (the "Registration Statement")
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended, with respect to the offer and sale by the Corporation of up to
_____________ shares of its common stock, without par value (the "Shares"), to
be issued to shareholders of UniBank upon consummation of the merger of UniBank
with and into The Citizens Banking Company, a wholly-owned subsidiary of the
Corporation, all as further described in the Registration Statement.

          We have reviewed the Registration Statement and the exhibits thereto
and have examined such other documents and matters of law as we have deemed
necessary for the purposes of this opinion. In rendering this opinion, we have
assumed there will be no changes in applicable law between the date of this
opinion and any date of issuance or delivery of the Shares.

          Based upon the foregoing, it is our opinion that when issued and sold
in the manner described in the Registration Statement (including all exhibits
thereto) and in compliance with the Securities Act of 1933, as amended, and all
applicable state securities laws, (i) the Shares will be duly authorized and
validly issued; (ii) the Shares will be fully paid and nonassessable, and (iii)
issuance of the Shares is not subject to any preemptive rights.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to us under the caption "Legal
Opinions" in the Proxy Statement and Prospectus included as part of the
Registration Statement.

                                        Respectfully submitted,

                                        /s/ Squire, Sanders & Dempsey L.L.P.
