                             QUESTIONS AND ANSWERS

     Q: WHY IS CITIZENS NATIONAL PROPOSING TO REORGANIZE INTO A HOLDING COMPANY
        STRUCTURE?

     A. We believe that the reorganization will give Citizens National greater
        flexibility in the services it provides to its customers and in
        responding to changing market conditions and the changing needs of the
        community.

     Q: WHAT DO I NEED TO DO NOW?

     A. Just indicate on your proxy card how you want to vote, and sign, date
        and return it to us. If you sign and send in your proxy and do not
        indicate how you want to vote, the proxies will vote your shares in
        favor of the formation of a holding company. Not returning your proxy,
        not voting at the special meeting or abstaining from voting has the
        effect of voting against the reorganization.

        If you hold Citizens National's common stock, you can choose to attend
        the special meeting and vote your shares in person instead of returning
        your completed proxy card. If you do return a proxy card, you may change
        your vote at any time up to the time of the vote by following the
        directions on page   .

     Q: WHAT WILL CITIZENS NATIONAL'S STOCKHOLDERS RECEIVE?

     A. Each non-dissenting shareholder will receive two shares of common stock
        of CNB Financial for each share of Citizens National's common stock.

     Q: WHEN DO YOU EXPECT THE REORGANIZATION TO TAKE PLACE?

     A. We are working toward completing the reorganization as quickly as
        possible. In addition to the approval of Citizens National's
        stockholders, we must obtain a number of regulatory approvals. We expect
        the reorganization to take place as soon as practicable after the
        special meeting and after we receive all regulatory approvals.

     Q: WHAT ARE THE INCOME TAX CONSEQUENCES OF THE MERGER TO ME?

     A. As a result of the reorganization, you will not recognize any gain or
        loss when you exchange your bank common stock for holding company common
        stock.

                                      -iii-

                                    SUMMARY

     The following is a brief summary of information located elsewhere in this
proxy statement/ prospectus. BEFORE YOU VOTE, PLEASE CAREFULLY CONSIDER ALL OF
THE INFORMATION CONTAINED IN THIS DOCUMENT.

SHAREHOLDERS WILL RECEIVE TWO SHARES OF CNB FINANCIAL'S COMMON STOCK FOR EACH
SHARE OF CITIZENS NATIONAL'S COMMON STOCK THEY OWN. (PAGE   )

     If Citizens National's shareholders approve the reorganization/merger and
the parties satisfy all of the other conditions in the agreement and plan of
merger, each share of Citizens National's common stock that is outstanding
immediately prior to the merger will automatically become two shares of CNB
Financial's common stock on the effective date of the merger.

THIS TRANSACTION WILL BE GENERALLY TAX FREE TO SHAREHOLDERS. (PAGE   )

     Subject to the limitations and assumptions described in "Federal Tax
Consequences of the Merger and Reorganization Into a Bank Holding Company," the
shareholders of Citizens National will not recognize any gain or loss as a
result of exchanging Citizens National's common stock for CNB Financial's common
stock.

CNB FINANCIAL'S GOVERNING DOCUMENTS CONTAIN A "FAIR PRICE" PROVISION WHICH IS
DESIGNED TO MAKE UNSOLICITED TAKEOVER ATTEMPTS MORE DIFFICULT. (PAGE   )

     CNB Financial's articles and bylaws contain a fair price provision.
Citizens National's corporate governance documents do not contain this type of
provision. Anti-takeover provisions such as a fair price provision are designed
to make unsolicited takeover attempts more difficult to accomplish.

CITIZENS NATIONAL'S SHAREHOLDERS HAVE DISSENTERS' RIGHTS. (PAGE   )

     If the merger occurs, any Citizens National stockholder may receive payment
of the value of his or her shares from Citizens Financial if the shareholder
follows the procedures set forth in 12 C.F.R. Sections 215a(b), (c) and (d).

CNB FINANCIAL'S COMMON STOCK IS NOT CURRENTLY LISTED ON AN EXCHANGE OR OTHER
TRADING FACILITY. (PAGE   )

     Citizens National's common stock currently is traded in privately
negotiated transactions. After the reorganization takes place and upon meeting
listing qualifications, we may in the future seek listing for trading on the
Nasdaq Stock Market's National Market Tier. We cannot predict when, if ever, we
would become eligible for listing.

CITIZENS NATIONAL AND CNB FINANCIAL ARE THE PARTIES TO THE MERGER. (PAGE   )

     Citizens National. Citizens National has operated as a national banking
association in Berkeley Springs, West Virginia, since June 20, 1934. The bank
provides a wide range of financial services for retail and institutional
customers. Citizens National operates as a full-service bank regulated by the
Office of the Comptroller of the Currency and the Board of Governors of the
Federal Reserve. The FDIC insures the bank's deposits, and therefore, the FDIC
also regulates the bank.

     CNB Financial. CNB Financial is a West Virginia corporation formed in March
2000. Its principal executive offices are located at 212 S. Washington Street,
P. O. Box 130, Berkeley Springs, West Virginia, and its telephone number is
(304) 258-1520.

THE MERGER. (PAGE   )

     After the merger, each shareholder of Citizens National will become a
shareholder of CNB Financial. Citizens National will be a wholly owned
subsidiary of CNB Financial.

                                        1
<PAGE>   8

RECAPITALIZATION STRUCTURE AFTER THE MERGER. (PAGE   )

     Immediately after the reorganization takes place (1) the holding company
will have outstanding twice the number of shares of common stock that Citizens
National had issued and outstanding immediately prior to the merger, (2) the
persons who held the Citizens National's common stock will be the same persons
who hold CNB Financial's common stock, and (3) the holding company will own all
of the shares of Citizens National.

TWO-THIRDS OF CITIZENS NATIONAL'S SHAREHOLDERS MUST APPROVE THE MERGER. (PAGE
  )

     Under federal law, at least two-thirds of our outstanding common stock must
approve the merger.

     If you held Citizens National's common stock at the close of business on
May 5, 2000, you are entitled to vote at the special meeting. Each share of
common stock is entitled to one vote.

     After careful consideration, Citizens National's board of directors
believes that the merger is in the best interests of Citizens National and its
stockholders and has approved the agreement and plan of merger and related plan
of merger. Citizens National's board of directors recommends that you vote FOR
approval of the agreement and plan of merger and related plan of merger.

                            SELECTED FINANCIAL DATA


     We are providing the following information to you to help you analyze
Citizens National's operations. We derived this information from audited
financial statements for 1995 through 1999 and unaudited financial statements
for the first quarters ended March 31, 2000 and 1999. We have adjusted the per
share data to reflect a 100% stock dividend declared on March 1, 1998. This
information is only a summary, and you should read it in conjunction with
Citizens National's historical financial statements and related notes contained
in this document. We have not provided any financial information for CNB
Financial because it was recently formed, and there are no operations to date.

                           FORWARD-LOOKING STATEMENTS

     When used in this proxy statement/prospectus, in Citizens National's or CNB
Financial's press releases or other public or shareholder communications, and in
oral statements made with the approval of the authorized executive officer, the
words or phrases "are expected to," "estimate," "is anticipated," "project,"
"will continue," "will likely result," "plans to" or similar expressions are
intended to identify "forward-looking statements." These types of statements are
subject to risks and uncertainties, including changes in economic conditions in
Citizens National's market area, changes in policies by regulatory agencies,
fluctuation in interest rates, demand for loans in Citizens National's market
area, and competition, that could cause actual results to differ materially from
what Citizens National or CNB Financial have presently anticipated or projected.
Citizens National and CNB Financial wish to caution readers not to place undue
reliance on any forward-looking statements, which speak only as of the date
made. Citizens National and CNB Financial wish to advise readers that factors
addressed within the proxy statement/prospectus could affect Citizens National's
financial performance and could cause Citizens National's actual results for
future periods to differ materially from any opinions or statements expressed
with respect to future periods in any current statements.

     Where any forward-looking statement includes a statement of the assumptions
or bases underlying the forward-looking statement, Citizens National and CNB
Financial caution that assumed facts or bases almost always vary from actual
results, and the differences between assumed facts or bases and actual results
can be material. We cannot assure you that any statement of expectation or
belief in any forward-looking statement will result, or be achieved or
accomplished.

                              THE SPECIAL MEETING

MATTERS TO BE VOTED ON AT THE SPECIAL MEETING

     At the special meeting, you will be asked to vote on an agreement and plan
of merger, dated as of April 5, 2000, and related plan of merger. CNB Financial
Services, Inc., is the new West Virginia corporation we organized to become the
holding company for Citizens National. If shareholders approve the agreement and
plan of merger, each outstanding share of common stock of Citizens National will
be converted into two shares of common stock of CNB Financial, and Citizens
National will become a wholly owned subsidiary of CNB Financial.

WHO IS ELIGIBLE TO VOTE


     If you held Citizens National common stock at the close of business on June
  , 2000, you may vote at the special meeting. On April 24, 2000, there were
229,024 shares of Citizens National common stock outstanding, held by 567
shareholders of record. Each share of common stock is entitled to one vote on
each matter properly presented at the special meeting.


QUORUM; REQUIRED VOTE

     Under our articles of incorporation and bylaws, at least two-thirds of our
outstanding common stock must approve the merger. The presence, in person or by
proxy, of at least a majority of the total number of shares of common stock
entitled to vote is necessary to constitute a quorum at the special meeting.
Shares that are subject to abstentions and broker non-votes are counted as
present for purposes of determining the presence of a quorum. If there are not
sufficient votes for a quorum, the special meeting may be adjourned or postponed
to permit further solicitation of proxies.

REVOCABILITY OF PROXIES

     The proxies we are soliciting under this proxy statement/prospectus, if
properly signed and returned to Citizens National and not revoked prior to their
use, will be voted in accordance with the instructions contained in the proxies.
EXECUTED PROXIES WITH NO INSTRUCTIONS INDICATED ON THE PROXY CARD WILL BE VOTED
FOR THE MERGER. Any stockholder who submits a proxy card has the power to revoke
it at any time before it is exercised by (1) filing a written notice of
revocation with Mr. Thomas F. Rokisky, Citizens National Bank of Berkeley
Springs, 212 S. Washington Street, P. O. Box 130, Berkeley Springs, West
Virginia 25411, (2) submitting a duly executed proxy card bearing a later date,
or (3) appearing at the special meeting and giving notice of his or her
intention to vote in person.

PROXY SOLICITATION

     In addition to soliciting proxies by mail, Citizens National's directors,
officers and employees may solicit proxies personally or by telephone without
receiving additional compensation for these activities. Citizens National will
also make arrangements with brokerage firms and other custodians, nominees and
fiduciaries to send proxy materials to their principals and will reimburse those
parties for their expenses in doing so.

         PROPOSED MERGER AND REORGANIZATION INTO A BANK HOLDING COMPANY

     We have attached a copy of the agreement and plan of merger to this proxy
statement/ prospectus as Appendix I. We urge you to read the entire agreement
and plan of merger because it is the document that governs the reorganization of
the bank into a one-bank holding company.

DESCRIPTION OF PROPOSED MERGER AND REORGANIZATION

     If Citizens National's stockholders approve the merger and all of the other
conditions in the agreement and plan of merger are satisfied, on the effective
date of the merger each share of Citizens National's common stock that is
outstanding immediately prior to the merger (other than dissenting shares) will
automatically by operation of law be exchanged for two shares of the holding
company's common stock.

     After the merger, the former holders of Citizens National's outstanding
common stock who do not exercise dissenters' rights will be the holders of all
of the outstanding shares of the holding company's common stock. At that point,
the holding company will own all of Citizens National's outstanding capital
stock. Because CNB Financial will hold all of the issued and outstanding capital
stock of Citizens National after the reorganization takes place, Citizens
National will be described as a "wholly owned" subsidiary of the holding company
following the merger.

     After this reorganization, Citizens National will continue its existing
business and operations as a wholly owned subsidiary of the holding company. At
that time, the consolidated capitalization, assets, liabilities, income and
financial statements of the holding company immediately following the
reorganization will be substantially the same as those of Citizens National
immediately prior to when the reorganization takes place. The articles of
incorporation and the bylaws of Citizens National will continue in effect, and
the transaction will not affect them in any material way. Citizens National will
continue to use the name "Citizens National Bank of Berkeley Springs," and
Citizens National's corporate existence will continue unimpaired.

     Citizens National's board of directors and the holding company believe that
the merger and reorganization into a holding company structure is in the best
interests of Citizens National's stockholders for the reasons we describe below.
The Citizens National and CNB Financial boards of directors have approved the
merger. If Citizens National's stockholders approve the agreement and plan of
merger and the other conditions described below under "Conditions That Must
Occur Before the Merger Can Occur" are satisfied, the merger will become
effective upon the filing of the plan of merger with the West Virginia Secretary
of State.

REASONS FOR FORMING THE HOLDING COMPANY

     The reasons for forming CNB Financial are to permit greater flexibility to
Citizens National in meeting the financial needs of its customers and to provide
a vehicle for growth and potential geographic diversification. In addition,
holding companies may redeem their shares, and banks may accept holding company
shares as collateral for loans (within certain limits). National banks do not
have these powers.

     Bank holding companies may also establish or acquire companies engaged in
activities closely related to banking with operations and offices located in
West Virginia and outside

                                        6
<PAGE>   13

the state as well. While the holding company is not presently engaged in
negotiations and there are no current arrangements or agreements for the
acquisition of other banks or companies engaged in activities closely related to
banking, and while we cannot assure you that we will make any acquisitions,
Citizens National's board of directors believes that the possibility of making
acquisitions which would be permissible if the reorganization takes place
represents a potentially attractive growth possibility.

     Citizens National's board of directors is also forming the holding company
to be in a position to take advantage of the provisions of the
Gramm-Leach-Bliley Act of 1999. This Act was passed by the United States
Congress on November 4, 1999, and signed by President Clinton on November 12,
1999. This Act repealed many of the restrictions on the activities that
financial institutions conduct. Under the Act, a bank holding company can
qualify as a "financial holding company" and engage in business activities which
were previously prohibited. The activities permitted to financial holding
companies under the Act are slightly broader than those permitted to banks.

     Citizens National's board of directors also believes that the holding
company may provide additional funding sources for Citizens National, as well as
better access to the capital markets. Additionally, Citizens National's board
believes a bank holding company will be in a better position to respond to the
competitive environment in which it is operating, characterized in larger part
by the activities of bank holding companies in West Virginia as well as
nationally. In general, the board of directors of Citizens National believes
that operating as a bank holding company will serve the interests of the banking
public and the stockholders of Citizens National by improving the capability for
service in a highly competitive environment.

RECOMMENDATION OF CITIZENS NATIONAL'S BOARD OF DIRECTORS

     After careful consideration, Citizens National's board of directors has
determined that the merger and reorganization is advisable and in the best
interests of Citizens National and its stockholders. Accordingly, the board has
approved the agreement and plan of merger and the related plan of merger and the
contemplated reorganization. CITIZENS NATIONAL'S BOARD OF DIRECTORS RECOMMENDS
THAT YOU VOTE FOR APPROVAL OF THE AGREEMENT AND PLAN OF MERGER AND THE RELATED
PLAN OF MERGER.

TREATMENT OF STOCK CERTIFICATES

     After the merger, Citizens National's shareholders who do not exercise
dissenters' rights will be entitled to exchange their Citizens National stock
certificates or the right to receive certificates for new certificates
evidencing two shares of holding company common stock for each share of Citizens
National common stock. Until exchanged, Citizens National stock certificates
will, for all purposes, represent two shares of holding company stock for each
Citizens National share previously represented. The holders of Citizens National
certificates who do not exercise dissenters' rights will have all of the rights
of holders of the holding company's shares.

     As soon as practicable after the merger takes place, we will send
instructions concerning stock certificates to all holders of record as of the
effective date of the merger.

<PAGE>   14

CONDITIONS THAT MUST OCCUR BEFORE THE MERGER CAN OCCUR

     The following summarizes some of the conditions that must occur before the
merger can take place:

     - two-thirds of the issued and outstanding shares of Citizens National
       common stock must approve the agreement and plan of merger and related
       plan of merger;

     - all regulatory approvals (or waiver or exemption from any required
       regulatory approval) and satisfaction of all other requirements required
       by law which are necessary to complete the merger, must be obtained, and
       all statutory waiting periods must expire, without the imposition of any
       condition or requirements that would materially and adversely affect the
       operations or business prospects of the holding company or Citizens
       National;

     - Citizens National must receive an opinion letter from Jackson & Kelly
       PLLC, counsel to Citizens National, regarding federal income tax
       consequences of the merger; and

     - Unless CNB Financial waives this condition, holders of more than 5% of
       Citizens National's common stock may not dissent from the merger.

FEDERAL TAX CONSEQUENCES OF THE MERGER AND REORGANIZATION INTO A BANK HOLDING
COMPANY

     The merger agreement expressly conditions the merger upon Citizens National
receiving an opinion of counsel from Jackson & Kelly PLLC with respect to United
States federal income taxation.

     We qualify the following summary of federal income tax consequences in its
entirety by referring you to the full text of Jackson & Kelly PLLC's opinion,
including that firm's assumptions. We have filed Jackson & Kelly PLLC's opinion
as Exhibit 8 to the registration statement of which this proxy
statement/prospectus is a part.

     This summary applies only to Citizens National's shareholders, if any, who
hold their common stock as a capital asset. This discussion does not address all
aspects of taxation that may be relevant to particular shareholders in light of
their personal investment or tax circumstances, or to certain types of
shareholders subject to special treatment under the federal income tax laws.
This opinion does not address tax issues relating to insurance companies,
financial institutions, broker-dealers, foreign corporations, persons who
receive stock through the exercise of stock options or otherwise as compensation
for services rendered and persons who are not citizens or residents of the
United States. It also does not discuss any state, local or foreign tax
considerations. Accordingly, we urge you to consult your own tax advisor as to
the specific tax consequences of the merger, including the applicable federal,
state, local and foreign tax consequences of the merger.

     We have not requested any ruling from the Internal Revenue Service as to
the federal income tax consequences of the merger. Jackson & Kelly PLLC's
opinion is not binding on the IRS or any court, and neither the IRS nor any
court is precluded from taking a different position. The Internal Revenue Code
governs some of the federal income tax consequences of the merger as to which
there are no final regulations and little or no judicial or administrative
guidance. Jackson & Kelly PLLC bases its opinion upon the federal income tax
laws in effect on the date of the opinion and as those laws are currently
interpreted. Future legislation, regulations, administrative rulings or court
decisions could adversely affect the accuracy of the statements.

                                        8
<PAGE>   15

     We condition the federal income tax consequences below upon, and Jackson &
Kelly PLLC bases its opinion upon, the accuracy of assumptions and
representations of fact that the parties to the merger agreement provided to
Jackson & Kelly PLLC. Jackson & Kelly PLLC has not independently verified these
assumptions and representations. These assumptions and representations include,
but are not limited to, the following:

     - that following the merger, CNB Financial will continue the historic
       business of Citizens National or use a significant portion of Citizens
       National's historic business assets in a business;

     - that a bona fide corporate business purpose exists for the merger; and

     - that in the merger shares of stock of Citizens National representing
       control of Citizens National will be exchanged solely for CNB Financial's
       common stock. For this purpose, control means 80% of the total combined
       voting power of all classes of stock entitled to vote and of at least 80%
       of the total number of shares of each other class of stock of Citizens
       National.

     As of the date of this proxy statement/prospectus, CNB Financial and
Citizens National believe that all of these assumptions are now, and will be at,
as of and after the time the merger becomes effective, accurate. If either CNB
Financial or Citizens National learns before that time that the assumptions are
false and that its counsel therefore believes that the merger is unlikely to be
treated as a tax-free reorganization, then additional shareholder approval will
be obtained before consummation of the merger.

     Subject to the limitations and assumptions described above, we anticipate
that Jackson & Kelly PLLC will render an opinion that the merger will have the
following federal income tax consequences:

     - The merger will constitute a reorganization within the meaning of
       Sections 368(a)(1)(A) and (a)(2)(E) of the Internal Revenue Code of 1986;

     - None of the parties to the merger agreement will recognize any gain or
       loss as a result of the merger;

     - Shareholders of Citizens National will not recognize any gain or loss as
       a result of their exchange of Citizens National's common stock for CNB
       Financial's common stock except to the extent any shareholder receives
       cash as a dissenting shareholder;

     - The holding period for Citizens National's shareholders of the CNB
       Financial's common stock they receive in the merger will include the
       period during which the Citizens National's stock was held, provided this
       stock was a capital asset in the hands of the holder on the date of
       exchange;

     - The federal income tax basis for Citizens National's shareholders of the
       CNB Financial's common stock they receive in the merger will be the same
       as the basis of the Citizens National's common stock shareholders
       exchange therefor; and

     - CNB Financial's payment of cash to Citizens National's shareholders in
       exchange for Citizens National common stock relating to the exercise of
       dissenter's rights will be treated as having been received as a
       distribution in redemption of a dissenting stockholder's Citizens
       National's common stock, subject to the provisions and limitations of
       Section 302 of the Internal Revenue Code. Where as a result of such
       distribution a stockholder owns no Citizens National's common stock
       either directly or through the application of Section 318(a) of the Code,
       the redemption will be a complete termination of interest within the
       meaning of Section 302(b)(3) of the Code and the cash will be treated as
       a distribution in full payment in exchange for his or

                                        9
<PAGE>   16

       her Citizens National's common stock, as provided in Section 302(a) of
       the Code. Under Section 1001 of the Code, gain or (subject to the
       limitations of Section 267 of the Code) loss will be realized and
       recognized to such stockholders in an amount equal to the difference
       between the amount of such cash and the adjusted basis of the Citizens
       National's common stock surrendered, as determined under Section 1011 of
       the Code. If the Citizens National's stockholder has held his or her
       stock for more than one year, the gain should be treated as long-term
       capital gain, provided that the shares were held as a capital asset on
       the date of the exchange.

     The tax consequences of the merger may vary depending upon your particular
circumstances. We urge you to consult your own tax advisor to determine the
particular tax consequences of the merger to you, including the applicability
and effect of any state, local or foreign income, property, transfer and other
tax laws.

ACCOUNTING TREATMENT

     The merger and reorganization into a bank holding company will be accounted
for as a change in corporate form with the historical basis of Citizens
National's assets, liabilities and stockholders' equity unchanged under the bank
holding company.

          COMPARISON OF CITIZENS NATIONAL'S AND CNB FINANCIAL'S STOCK

     The respective articles of incorporation and bylaws of Citizens National
and CNB Financial govern the bank's and the holding company's shareholders. In
many respects, the rights of CNB Financial's shareholders will be similar to
those of Citizens National's shareholders. For example:

     - Holders of common stock of each corporation are entitled to one vote for
       each share of common stock and to receive pro rata any assets distributed
       to shareholders upon liquidation.

     - Shareholders of neither corporation have preemptive rights.

     - The shareholders of both corporations have the right to dissent from
       certain corporate transactions and to elect dissenters' rights.

     - The board of directors of each corporation may fill a vacancy of the
       board occurring during the course of the year, including a vacancy
       created by an increase in the number of directors.

     Below we discuss the various attributes of owning CNB Financial's common
stock and Citizens National's common stock.

ISSUANCE OF CAPITAL STOCK

     Under Citizens National's articles of incorporation, Citizens National's
authorized capital stock is 600,000 shares of common stock, par value $10.00 per
share, of which 229,024 shares are issued and outstanding as of April 24, 2000.
Under the holding company's articles of incorporation, the authorized capital
stock of the holding company is 5,000,000 shares of common stock, par value
$1.00 per share.

     Under the agreement and plan of merger, CNB Financial will issue
approximately 458,048 shares of its common stock in exchange for all of the
outstanding shares of Citizens National's common stock. The balance of CNB
Financial's authorized capital stock will be

                                       10
<PAGE>   17

available for issuance when and as the board of directors of CNB Financial
determines. CNB Financial could issue that common stock to raise additional
capital in connection with the acquisition of other businesses or for other
appropriate purposes. The board of directors of CNB Financial will have the
authority to issue common stock to the extent of the present number of
authorized and unissued shares, without obtaining shareholder approval. If
additional holding company common stock is issued, the existing holders of the
holding company's common stock would own a proportionately smaller portion of
the total number of issued and outstanding common stock, unless they acquire a
pro-rata portion of the new issue.

DIVIDENDS AND DIVIDEND RIGHTS

     Citizens National's stockholders are entitled to receive dividends when and
as declared by its board of directors, subject to various regulatory
restrictions. In certain instances, a national bank must obtain approval of the
Comptroller of the Currency before paying dividends. Federal law prohibits
national banks from paying dividends greater than the bank's undivided profits
after deducting statutory bad debt in excess of the bank's allowance for loan
losses.

     CNB Financial's future cash dividends will depend on its consolidated
earnings, general economic conditions, financial condition of its subsidiaries
and other factors generally affecting dividend policy. CNB Financial's
stockholders are entitled to receive dividends when and as declared by its board
of directors subject to the restrictions under federal law and the regulations
of the Office of the Comptroller of the Currency. Generally, the Office of the
Comptroller of the Currency must approve any dividends in excess of the sum of
current year's income and net profits retained for the prior two years.
Following the merger's completion, funds for the payment of cash dividends and
expenses of CNB Financial will come from cash dividends from Citizens National.

VOTING RIGHTS

     All voting rights with respect to Citizens National are vested in the
holders of the bank's common stock. All voting rights with respect to CNB
Financial will be vested in the holders of CNB Financial's common stock.

     In the election of directors, the shareholders of CNB Financial and
Citizens National have the right to vote the number of shares owned by them for
as many persons as there are directors to be elected, or to cumulate such shares
and give one candidate as many votes as the number of directors to be elected
multiplied by the number of shares they own, or to distribute them on the same
principle among as many candidates as they may decide. For all other purposes,
each share is entitled to one vote.

PREEMPTIVE RIGHTS

     Holders of Citizens National's common stock do not have preemptive rights
to subscribe to a pro-rata share of any future offers of shares by the bank. The
holders of common stock of CNB Financial will have no preemptive rights to
subscribe to any additional securities which CNB Financial may issue. If CNB
Financial should decide to issue any or all of these shares, the effect would be
to dilute the percentage ownership of the shareholders who do not purchase a
pro-rata portion of the shares issued.

                                       11
<PAGE>   18

LIQUIDATION RIGHTS

     The holders of Citizens National's common stock are entitled to share
equally in the net assets of the bank in the event of liquidation or
dissolution. After the merger's completion, holders of Citizens National's
common stock converted to CNB Financial's common stock will be entitled to share
equally in the net assets of the holding company in the event of liquidation or
dissolution, subject to the preferential rights, if any, of the holders of any
outstanding senior securities. At this time, there are no senior securities of
the holding company issued or outstanding, and the holding company currently has
no plan to issue senior securities.

ASSESSMENT OF SHARES

     The shares of CNB Financial's common stock are fully paid and
non-assessable. Federal regulations provide that the outstanding shares of
Citizens National held by the officers and directors of the bank may be assessed
if its common stock becomes impaired by losses or otherwise.

INDEMNIFICATION

     Directors and officers of CNB Financial or persons serving at the request
of CNB Financial as directors, officers, employees or agents of another
corporation or organization (including any of its subsidiaries) are entitled to
indemnification as provided in its articles of incorporation.

     In general, indemnification is provided for reasonable costs and expenses,
fees and reasonable payments in settlement, except in matters in which the
person is adjudged to be liable for gross negligence, willful misconduct, or
criminal acts.

     The bank's articles of incorporation contains similar provisions.

     Although we believe the foregoing describes the material similarities and
differences between the rights of CNB Financial's and Citizens National's
shareholders, it is not exhaustive, and we encourage you to refer to the West
Virginia Corporation Act and the articles and bylaws of both CNB Financial and
Citizens National.

FAIR PRICE PROVISION

     Citizens National's articles of incorporation and bylaws do not contain a
fair price provision. However, CNB Financial's articles of incorporation contain
this provision.

     The fair price provision requires the approval of at least 80% of CNB
Financial's shares entitled to vote to approve transactions with an interested
shareholder except in cases where either (1) price criteria and procedural
requirements are satisfied, or (2) a majority of CNB Financial's board of
directors recommends the transaction to the shareholders. If the minimum price
criteria and procedural requirements are met or the requisite approval of CNB
Financial's board of directors are given, the normal requirements of West
Virginia law would apply.

     An "interested shareholder" is any person, other than CNB Financial or any
of its subsidiaries, who is, or who was within the two-year period immediately
before the announcement of a proposed business combination, the beneficial owner
of more than 10% of CNB Financial's voting power. It also includes any person
who is an assignee of, or has

                                       12
<PAGE>   19

succeeded to, any shares of voting stock in a transaction not involving a public
offering which were at any time within the prior two-year period beneficially
owned by interested shareholders. A "disinterested director" is any member of
the board of directors of CNB Financial who is not affiliated with an interested
shareholder and who was a director of CNB Financial prior to the time the
interested shareholder became an interested shareholder. It also includes any
successor to a disinterested director who is not affiliated with an interested
shareholder and who was recommended by a majority of the disinterested directors
then on the board.

     ADVANTAGES OF CNB FINANCIAL'S FAIR PRICE PROVISION. The fair price
provision may constitute a defensive measure because it may discourage or deter
a third party from attempting to acquire control of CNB Financial. The purpose
of this provision is to discourage and to insulate the corporation against
hostile takeover efforts which CNB Financial's board of directors might
determine are not in the best interests of CNB Financial or its shareholders. We
believe that the fair price provision is a reasonable precaution to ensure that
a party seeking control will discuss its proposal with management.

     DISADVANTAGES OF CNB FINANCIAL'S FAIR PRICE PROVISION. The fair price
provision may be beneficial to management in a hostile takeover attempt, making
it more difficult to effect changes, and at the same time, adversely affecting
shareholders who might wish to participate in a takeover attempt.

                              REGULATORY APPROVALS

     For the merger to occur, the holding company and Citizens National must
have received approvals from the Office of the Comptroller of the Currency and
the Federal Reserve Board.

                       RIGHTS OF DISSENTING SHAREHOLDERS

     Citizens National's shareholders will be voting on the agreement and plan
of merger. If you object to the reorganization and comply with 12 C.F.R.
Sections 215a(b), (c) and (d), you are entitled to payment of the fair value of
your shares. The following is a brief summary of the steps you must take to
perfect dissenters' rights. The summary may not contain all information that is
important to investors, even though it contains all material terms and
conditions. We have reproduced for you the provisions of 12 C.F.R. Sections
215a(b), (c) and (d) as Appendix II to this proxy statement/prospectus.

     YOU MUST VOTE AGAINST THE MERGER OR GIVE WRITTEN NOTICE OF YOUR DISSENT. If
the Comptroller of the Currency approves the merger and if the merger is
approved by two-thirds of the number of shares outstanding, you may receive the
fair value of your shares if you vote against the merger or give written notice
at or prior to the special meeting to Thomas F. Rokisky that you dissent from
the plan of merger. You will be entitled to receive the value of your shares
when the Comptroller of the Currency approves the merger and plan of merger upon
written request made to CNB Financial at any time before 30 days after the date
of consummation of the merger. Your stock certificates must accompany this
written request.

     THE VALUE OF YOUR SHARES WILL BE DETERMINED AS OF THE EFFECTIVE DATE OF THE
MERGER. An appraisal committee consisting of three persons composed of one
selected by the vote of the holders of a majority of the bank's common stock,
one selected by the directors of the

                                       13
<PAGE>   20

bank and one selected by each of the foregoing shall make up the committee. The
valuation agreed upon by any of the two of the three appraisers shall govern.

     If the value so fixed is not satisfactory to any dissenting shareholder who
has requested payment, that shareholder may, within five days after being
notified of the appraised value of the shares, appeal to the Comptroller of the
Currency. In this event, the Comptroller of the Currency shall see to it that a
reappraisal be made and this appraisal will be the final and binding value of
the shares.

     If within 90 days from the date of consummating the merger one or more of
the appraisers is not selected or the appraisers fail to determine the value of
the shares, the Comptroller of the Currency will upon written request of any
interested party cause an appraiser to make a final and binding appraisal. CNB
Financial will pay the expenses of the Comptroller in making the reappraisal or
the appraisal. CNB Financial will promptly pay to the dissenting shareholder the
value of the shares.

     The shares of stock of CNB Financial which it would have delivered to a
dissenting shareholder had they not requested payment shall be sold by CNB
Financial at an advertised public auction, and CNB Financial will have the right
to purchase any of those shares at the public auction if it is the highest
bidder for the purpose of reselling the shares within 30 days to anyone and at a
price not less than the par value of the shares. If the shares are sold at
public auction at a price greater than the amount paid to a dissenting
shareholder, the excess of the sale price will be paid to the dissenting
shareholder.

        MARKET PRICE OF CITIZENS NATIONAL'S CAPITAL STOCK AND DIVIDENDS

     The price of Citizens National's common stock ranged from $100.00 to
$150.00 in 1999, and from $75.00 to $90.00 in 1998. We have adjusted these
amounts to reflect a two-for-one stock split effective in the form of a 100%
stock dividend on March 1, 1998. The bank's stock is not traded on an
established exchange and there are no market makers. We use the prices listed
below upon information available to us through discussions with the bank's
shareholders. Prices reflect amounts purchasers of the stock made and may
include commissions or fees. We have not attempted to determine the prices for
every sale made during these periods. The bank's ability to pay dividends is
subject to limitations of national banking laws. As of April 24, 2000, Citizens
National's common stock was held of record by 567 persons.

     After the reorganization takes place, we anticipate that the holding
company will obtain the funds needed for payment of its dividends and expenses
from Citizens National, chiefly in the form of dividends. The following table
sets forth dividends declared per share of Citizens National's common stock for
the periods indicated. The ability of Citizens National and CNB Financial to pay
dividends is and will be, respectively, subject to the restrictions we described
in "Supervision and Regulation." We have adjusted the per share data to reflect
a 100% stock dividend declared on March 1, 1998.

                                   MANAGEMENT

     After the merger takes place, the initial directors of the holding company
will be the same as those currently serving as Citizens National's directors. We
will deem approval of the agreement and plan of merger by Citizens National's
shareholders to be a confirmation by the holding company's stockholders of those
persons as the directors of the holding company without further action and
without changes in classes or terms.

(1) Mr. Kesecker is not an employee of the Bank.

MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

     Citizens National's board of directors has a standing audit committee and
personnel committee, but does not have a standing nominating committee.

     The functions of the audit committee include meeting with the independent
public accountants to review the scope of audit services, significant accounting
changes, audit conclusions regarding significant accounting estimates,
assessments as to the adequacy of internal controls and the resolution of any
reportable conditions or weaknesses, and compliance with laws and regulations;
overseeing the internal audit function; reviewing regulatory examination reports
and management's responses to those reports; and reviewing period reports from
the loan review function. Members of the audit committee during 1999 were
Charles S. Trump, IV, Chairman, Messrs. Yost, Barker, McGraw and Dick. Mr.
Kesecker serves as an ex-officio member of this committee. The audit committee
met four times during the year.

     The functions of the personnel committee include reviewing benefit and
salary administration programs and increases in salaries for officers and
employees. Members of the personnel committee during 1999 were Jay E. Dick,
Chairman, Messrs. Andrews, Hawvermale, Eppinger, Trump and Ayers. Mr. Kesecker
serves as an ex-officio member of this committee. The personnel committee met
one time during the year.

                                       17
<PAGE>   24

     There were 26 meetings of the bank's board of directors and 31 meetings of
committees of the board of directors of Citizens National during 1999. No
director attended fewer than 75 percent of the aggregate number of meetings of
the board of directors and of the various committees on which they served.

COMPENSATION OF BANK DIRECTORS

     Bank directors receive $125 for each board meeting they attend, $150 for
each discount committee meeting and $75 for other committee meetings. In
addition, each director receives a fee of $4,150 per year. The chairman of the
board receives $3,500 per year and the vice chairman receives $1,000 per year.
Other than the supplemental insurance plan described below, there are no other
special arrangements with any of the directors. In 1999, the board of directors
of the bank received $137,002, in the aggregate, for all board of directors'
meetings attended and all fees paid.

     The bank maintains a supplemental insurance plan for directors pursuant to
which a director may elect to defer receipt of a portion of fees for board
meetings for at least four years or until he reaches age 65, whichever is later.
An amount equal to fees waived in addition to interest at an annual rate of 10%
per year will be paid to each participating director or his designated
beneficiary during a period of 10 years after the director reaches age 65. Fees
and interest the bank pays will be recovered through insurance policies on the
lives of participating directors. The bank uses funds from the deferred fees of
a participating director to pay the premium costs for the insurance policies.
The cost of the insurance premiums in 1999 was $49,944.

BANK EXECUTIVE COMPENSATION

     The following table sets forth the compensation of the bank's chief
executive officer for the years 1999 and 1998. No executive officers received

(1) The bank's group life and health insurance program, which the bank pays, is
    available to all full-time employees. In accordance with IRS Code Section
    79, the bank adds the cost of group term life insurance coverage for an
    individual in excess of $50,000 to the individual's earnings and includes it
    in salary. This figure also includes board fees earned and the bank's
    contributions to the individual's 401(k) retirement savings program to which
    the individual has a vested interest.

(2) We do not and cannot calculate the allocation to specific participants of
    the bank's contributions to the defined benefit pension plan. The bank made
    contributions of $120,095 and $62,353 in 1999 and 1998, respectively.

     The bank does not maintain any form of stock option, stock appreciation
rights, or other long-term compensation plans.

PENSION PLAN

     The bank maintains a non-contributory defined benefit pension plan with
employer contributions being based on a pension formula, which targets a
specified monthly benefit for each plan participant at retirement. This defined
benefit becomes the basis for a contribution to the plan for each eligible
participant. The normal retirement date for employees is the later of the
participant's 65th birthday, or the fifth anniversary of the participant joining
the plan. An employee must be at least 21 years of age and have one full year of
service to become a plan participant. Full vesting in accumulated plan benefits
occurs at the end of five years of service. There is no partial vesting. For the
1999 plan year, the employer contribution for all plan participants was
$120,095.

401(k) PROFIT SHARING PLAN

     The bank maintains a 401(k) profit sharing plan that generally covers all
employees who have completed one year of service. The bank bases contributions
to the plan on bank performance as a percentage of assets and computes as a
percentage of the participant's total deferrals into the plan. The bank makes
the payment of benefits to participants at death, disability, termination or
retirement. Contributions to the plan for all employees charged to operations
during 1999 amounted to $19,800.

DEFERRED COMPENSATION

     The bank maintains a deferred compensation plan for directors. This plan
provides payments after retirement, which the bank will pay from general funds.
The bank purchases and is the beneficiary of insurance on the lives of
participants and the bank uses the proceeds to help recover the net after-tax
cost of the benefits and insurance premiums it pays. At December 31, 1999, these
policies had a net accumulated cash value of $670,734.

COMPENSATION FOR CNB FINANCIAL'S EXECUTIVE OFFICERS AND DIRECTORS

     CNB Financial does not currently compensate its directors for regular or
special board meetings attended, but it intends to compensate directors in the
future. Thomas F. Rokisky will serve as president and chief executive officer of
the holding company and will continue to serve as president and chief executive
officer of Citizens National.

OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

CERTAIN TRANSACTIONS

     The bank has had and intends to continue to have banking and financial
transactions in the ordinary course of business with directors and executive
officers of the bank, CNB Financial and their associates. Total loans
outstanding from the bank at December 31, 1999, to the bank's officers and
directors as a group and members of their immediate families and companies in
which they had an ownership interest of 10% or more was $1,463,356 or
approximately 12.0% of total equity capital. These loans do not involve more
than the normal risk of collectibility or present other unfavorable features.

                  DESCRIPTION OF CITIZENS NATIONAL'S BUSINESS

     Citizens National began banking operations in Berkeley Springs, Morgan
County, West Virginia, in 1934.

BUSINESS OF CITIZENS NATIONAL

     Citizens National is a full-service commercial bank. It accepts time,
demand and savings deposits, including NOW accounts, regular savings accounts,
money market accounts, fixed-rate certificates of deposit and club accounts. In
addition, the bank provides safe deposit box rentals, wire transfer services and
24-hour ATM services through a regional network known as "Honor." Honor is a
participant in the nationwide Cirrus network.

     The bank offers a full spectrum of lending services to its customers,
including commercial loans and lines of credit, residential real estate loans,
consumer installment loans and other personal loans. Commercial loans are
generally secured by various collateral, including commercial real estate,
accounts receivable and business machinery and equipment. Residential real
estate loans consist primarily of mortgages on the borrower's personal
residence, and are typically secured by a first lien on the subject property.
Consumer and personal loans are generally secured, often by first liens on
automobiles, consumer goods or depository accounts. The bank makes a special
effort to keep loan products as flexible as possible within the guidelines of
prudent banking practices in terms of interest rate risk and credit risk. The
bank's lending personnel adhere to established lending limits and authorities
based on each individual's lending expertise and experience.

     When considering loan requests, the bank takes into consideration the cash
flow and financial condition of the borrower, the value of the underlying
collateral, if any, and the borrower's character and integrity. Bank personnel
evaluate these factors in a number of ways, including analyzing of financial
statements, conducting credit reviews and visiting the borrower's place of
business.

EMPLOYEES


     As of June   , 2000, Citizens National and its subsidiary employed
full-time equivalent employees.


COMPETITION

     The banking business is highly competitive. Citizens National faces a high
degree of competition for all of its services from local banks. Within its
market area of Morgan County, the eastern section of Berkeley County in West
Virginia and Washington County in

                                       21
<PAGE>   28

Maryland, there exists 11 competing commercial banks with 25 offices. Total
deposits of those commercial banks as of June 30, 1999, exceeded $639 million.
The three largest competitors are One Valley Bank-East, N.A., F & M Bank, West
Virginia, and The Huntington National Bank.

     Nonbank competition has also increased in recent years locally by the
establishment of finance companies and the expansion of insurance operations and
credit unions as well as from mutual funds located throughout the country.

     West Virginia banks are allowed unlimited branch banking throughout the
state. The Interstate Banking and Branch Efficiency Act of 1994 also authorizes
interstate branching by acquisition and consolidation nationwide. This law
provides opportunities for the bank, but it also serves to intensify future
competition.

     The principal competitive factors in the markets for deposits and loans are
interest rates, either paid on deposits or charged on loans.

     The principal economic risk associated with the bank's lending activities
is the creditworthiness of the bank's prospective borrowers. With any loan
category, the level of risk increases or decreases depending on economic
conditions prevailing from time to time. The bank makes a substantial portion of
its loans to working individuals, small business and professional persons.
During 1999, the bank's loan portfolio consisted of the following:

</TABLE>

     The bank's lending activities are subject to a variety of lending limits
that federal law imposes. While differing limits apply in certain circumstances
based on the type of loan or the nature of the borrower (including the
borrower's relationship to the bank), in general, the bank is subject to a
loan-to-one borrower limit of an amount equal to (1) 15% of the bank's
unimpaired capital and surplus in the case of loans which are not fully secured
by readily marketable collateral, or (2) 25% of the unimpaired capital and
surplus if the excess over 15% is fully secured by readily marketable
collateral.

     The bank may not make any extensions of credit to any director, executive
officer or principal shareholder of the bank, or to any related interest of such
a person, unless the board of directors approves the extension of credit.
Additionally, the bank cannot make loans to an affiliate of the bank on terms
and conditions more favorable than would be available to a person not affiliated
with the bank.

     The bank also owns an insurance agency, CNB Insurance Services, Inc. CNB
Insurance is a property and casualty insurance agency selling primarily personal
lines of insurance in Morgan and Berkeley Counties.

     The FDIC insures all deposit accounts up to $100,000 per depositor, subject
to aggregation rules.

PROPERTY

     The principal executive office and main banking office is located at 212 S.
Washington Street, Berkeley Springs, West Virginia. In addition, the bank has
owned and operated a full-service branch bank located at 2450 Valley Road,
Berkeley Springs, West Virginia, since 1991. In October 1998, the bank opened an
additional full-service branch located at 2646 Hedgesville Road, Martinsburg,
West Virginia. Each location provides ATM services in addition to traditional
lobby and drive-in services. During 1998, the bank purchased two cash machines
and placed them at Cacapon State Park Lodge and the Woods Resort. In November of
1998, the bank acquired CNB Insurance Services, Inc., which is operated out of
the main office in Berkeley Springs. The main office and branches are owned free
and clear of any indebtedness. The net book value of the bank's premises and
equipment as of December 31, 1999, is $3.4 million.

                           SUPERVISION AND REGULATION

     Citizens National, as a national banking association, is subject to
supervision, examination and regulation by the Office of the Comptroller of the
Currency. It is also a member of the Federal Reserve System, and as such is
subject to applicable provisions of the Federal Reserve Act and regulations
issued thereunder.

     The Federal Deposit Insurance Corporation insures the bank's deposits to
the extent the law allows. Accordingly, the FDIC also regulates the bank.

     The Community Reinvestment Act of 1977 ("CRA") requires the Comptroller of
the Currency to assess the record of the financial institutions and regulates it
to determine if those institutions meet the community's credit needs (including
low-to-moderate income neighborhoods) and to take this record into account when
it evaluates any application made by any institution for, among other things,
approval of a branch or other deposit facility, office relocation, or the merger
with or acquisition of assets of another bank. In its most recent examination,
the bank received a satisfactory CRA rating.

     The bank is subject to various capital requirements under federal banking
regulations including the Federal Deposit Insurance Corporation Improvement Act
of 1991. Quantitative measures established by those regulations ensure the bank
maintains minimum capital levels. Note 17 to the Consolidated Financial
Statements summarizes those measures. Note 17 also contains the bank's
regulatory capital ratios at December 31, 1999, and December 31, 1998. Those
ratios show that the bank satisfied the requirements necessary to be categorized
as well capitalized. This is the highest category established under the
regulations. As a well capitalized institution, Citizens National may engage in
a wider range of banking activities.

     Another requirement of the Federal Deposit Insurance Corporation
Improvement Act of 1991 is that federal banking agencies must prescribe
regulations relating to various operational areas of banks and bank holding
companies. These include standards for internal audit systems, loan
documentation, information systems, internal controls, credit underwriting,
interest rate exposure, asset growth, compensation, and such other standards as
the agency deems appropriate.

GRAMM-LEACH-BLILEY ACT OF 1999

     On November 4, 1999, Congress adopted the Gramm-Leach-Bliley Act of 1999.
This Act, also known as the Financial Modernization Law, repealed a number of
federal
                                       23
<PAGE>   30

limitations on the powers of banks and bank holding companies originally adopted
in the 1930's. Under the Act, banks, insurance companies, securities firms and
other service providers may now affiliate. In addition to broadening the powers
of banks, the Act created a new form of entity, called a financial holding
company, which may engage in any activity that is financial in nature or
incidental or complementary to financial activities. CNB Financial intends to
become a financial holding company.

     The Federal Reserve Board provides the principal regulatory supervision of
financial services permitted under the Act. However, the Securities and Exchange
Commission and state insurance and securities regulators also assume substantial
supervisory powers and responsibilities.

     The Act addresses a variety of other matters, including customer privacy
issues. The obtaining of certain types of information by false or fraudulent
pretenses is a crime. Banks and other financial institutions must notify their
customers about their policies on sharing information with certain third parties
In some instances, customers may refuse to permit their information to be
shared. The Act also requires disclosures of certain ATM fees and contains
certain amendments to the federal Community Reinvestment Act. The Act became
effective 120 days after its passage.


                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF


                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS



FOR THE QUARTERS ENDED MARCH 31, 2000 AND 1999



GENERAL



     Citizens National is a national banking association which provides banking
services to individuals and businesses. The bank's primary regulators are the
Office of the Comptroller of the Currency (OCC) and the Federal Deposit
Insurance Corporation (FDIC). On November 15, 1998, Citizens National formed CNB
Insurance Services, Inc, a wholly owned subsidiary. CNB Insurance Services, Inc
is a property and casualty insurance agency selling primarily personal lines of
insurance.



     In March 2000, the bank's Board of Directors approved the formation of CNB
Financial, a financial services holding company. A special meeting of the bank's
shareholders will be held in June 2000 for the shareholders to vote on an
Agreement and Plan of Merger between the Bank and CNB Financial, whereby the
bank will become a wholly-owned subsidiary of CNB Financial and the shareholders
of the bank will become shareholders of CNB Financial. If the reorganization is
approved, each bank shareholder will receive two shares of CNB Financial's stock
for each share of the bank's common stock.



     The following discussion and analysis presents the significant changes in
financial condition and results of operations of Citizens National, for the
three months ended March 31, 2000 and 1999. This discussion may include
forward-looking statements based upon management's expectations; actual results
may differ. Amounts and percentages used in this discussion have been rounded.
All average balances are based on monthly averages.


                                       24
<PAGE>   31


EARNINGS SUMMARY



     Net income for the three months ended March 31, 2000 was $399,000, or $1.74
per share compared to $313,000 or $1.37 per share for the same period in 1999.
Annualized return on average assets and average equity were 1.16% and 12.80%
respectively, for the three months ended March 31, 2000 compared with .96% and
9.88%, respectively, for the three months ended March 31, 1999. The factors
influencing the bank's results of operations are addressed in the following
sections of this report.



NET INTEREST INCOME



     Net interest income represents the primary component of the bank's
earnings. It is the difference between interest and fee income related to
earning assets and interest expense incurred to carry interest-bearing
liabilities. Net interest income is impacted by changes in the volume and mix of
interest earning assets and interest bearing liabilities, as well as by changing
interest rates. In order to manage these changes, their impact on net interest
income and the risk associated with them, the bank utilizes an ongoing
asset/liability management program. This program includes analysis of the
difference between rate sensitive assets and rate sensitive liabilities,
earnings sensitivity to rate changes, and source and use of funds. A discussion
of net interest income and the factors impacting it is presented below.



     Net interest income for the three months ended March 31, 2000 increased by
$130,000 or 10.3% over the same period in 1999. Interest income for the three
months ended March 31, 2000 increased by $252,000 or 10.6% compared to the same
period in 1999, while interest expense increased by $122,000 or 11.0% during the
three months ended March 31, 2000 as compared to the same period in the prior
year.



     Increased net interest income for the three month period is attributable to
a higher level of net interest earning assets and an increase in the net
interest margin. Total interest income increased for the three month period in
2000 compared to the same periods in 1999 as a result of an increase in the
average balance of loans and the average rates earned thereon, which more than
offset the decrease in the average balance of federal funds sold and investment
securities. Total interest expense increased for the three month period in 2000
compared to the same periods in 1999 as a result of an increase in the average
balance of time deposits and NOW accounts and an increase in the average rates
earned thereon.



     The net interest margin is impacted by the change in the spread between
yields on earning assets and rates paid on interest bearing liabilities. Net
interest margin increased slightly in 2000 from 1999. See Table 1 - Distribution
of Assets, Liabilities, and Shareholders' Equity; Interest Rates and Interest
Differential.

PROVISION FOR LOAN LOSSES



     The amount charged to provision for loan losses is based on Management's
evaluation of the loan portfolio. Management determines the adequacy of the
allowance for loan losses, based on past loan loss experience, current economic
conditions, composition of the loan portfolio, and the anticipated potential for
future loss.



     The provision for loan losses for the three months ended March 31, 2000
decreased by $12,000 or 28.6% to $30,000 from $42,000 at March 31, 1999. The
decrease in the provision was the result of lower levels of nonperforming loans.
See "Nonperforming Assets and Allowance for Loan Losses" for further discussion.



NONINTEREST INCOME



     Noninterest income for the three months ended March 31, 2000 increased
$227,000 or 164% to $365,000 from $138,000 in the first quarter of 1999. The
increase was primarily due to a gain recognized on stock received from the
demutualization of an insurance company of $196,000. The bank received the stock
in exchange for its previous membership interest as a participating
policyholder. Also, service charges on deposit accounts, debit card fees and
trust income slightly increased. Trust assets under management reached $19.8
million at March 31, 2000, a 24.5% increase from $15.9 million at March 31,
1999.



NONINTEREST EXPENSES



     Noninterest expenses for the three months ended March 31, 2000 increased
$231,000 or 25.9% to $1.1 million from $893,000 in the first quarter of 1999.
These increases were primarily due to the loss on abandonment of fixed assets,
expenses related to the renovations of the main office and the professional
costs associated with the formation of CNB Financial Services, Inc.



     Other operating expenses which increased were salaries and employee
benefits, Automated Teller Machine (ATM) expense, trust, and FDIC assessment.
Salaries and employee benefits increased as a result of increased personnel and
pension expense.



INCOME TAXES



     The Bank's provision for income taxes increased $53,000 or 34.5% to
$205,000 for the three months ended March 31, 2000. The effective tax rates for
the first quarter of 2000 and 1999 were 34.0% and 32.8%, respectively. The
increase in the income tax provision in 2000 is attributable to increased
taxable income. The bank's income tax expense differs from the amount computed
at statutory rates primarily due to the tax-exempt earnings from certain
investment securities.



FINANCIAL CONDITION



     The bank's total assets increased $1.8 million or 1.3% to $140.4 million
from December 31, 1999 to March 31, 2000, due primarily to a $1.8 million
increase in investment securities and a $2.0 million increase in loans, which
was partially offset by a $1.9 million decrease in cash and cash equivalents.
The bank's total liabilities increased $1.5 million or 1.2% to $127.9 million.
Shareholders' equity increased $324,000 to $12.6 million at March 31, 2000
primarily due to net income of $399,000 offset by a $75,000 decrease in
accumulated other comprehensive income. The only component of


                                       27
<PAGE>   34


accumulated other comprehensive income at March 31, 2000 was unrealized losses
on available for sale securities, net of deferred income taxes. The unrealized
losses are primarily a function of available market interest rates relative to
the yield being generated on the available for sale portfolio. No earnings
impact results, however, unless the securities are actually sold.



LOAN PORTFOLIO



     At March 31, 2000, total loans increased $1.9 million or 2.0% to $99.1
million from $97.2 million at December 31, 1999. The loan mix did not change in
any material respect compared with December 31, 1999. The loan portfolio
increase is the result of developing new real estate loan programs and efforts
to develop new commercial and indirect lending relationships in the bank's
expanded market area of Berkeley County, West Virginia. The bank feels
additional growth in all lending areas is possible during the remainder of 2000.



NONPERFORMING ASSETS AND ALLOWANCE FOR LOAN LOSSES



     Nonperforming assets consist of nonaccrual loans, loans which are past due
90 days or more and still accruing interest, restructured loans and other real
estate owned. The following table summarized the Bank's nonperforming assets as
of the periods shown:

     As of March 31, 2000, the bank has no loans which are considered to be
impaired and is not aware of any potential problem loans other than those which
are on nonaccrual status or past due ninety days or more and still accruing
interest.



     The bank maintains its allowance for loan losses at a level deemed
sufficient to provide for estimated potential losses in the credit extension
process. All losses which may be reasonably anticipated are accounted for in the
allowance for loan losses. Management makes this determination quarterly by its
analysis of overall loan quality, changes in the mix and

conditions, information about specific borrowers and other factors.



     An analysis of the allowance for loan losses is summarized below:

DEPOSITS



     The bank's deposits increased $37,000 or .03% during the three months ended
March 31, 2000. The deposit mix experienced changes during the first quarter
2000 by a decrease in rate sensitive jumbo certificates of deposit and an
offsetting increase in other certificates of deposit.



CAPITAL RESOURCES



     Shareholders' equity increased $324,000 or 2.7% during the first three
months of 2000 due to $399,000 in net income offset by a decrease in
comprehensive income of $75,000. The Bank is subject to regulations of the
Office of the Comptroller of the Currency that impose certain minimum regulatory
capital requirements. Under each measure, the bank was substantially in excess
of the minimum regulatory requirements, and, by definition was "well
capitalized" at March 31, 2000. The following table summarized, as of March 31,
2000, the bank's capital ratios.

     EARNINGS SUMMARY. Citizens National had net income totaling $1.2 million or
$5.33 per share, $1.3 million or $5.68 per share, and $1.3 million or $5.75 per
share for fiscal years 1999, 1998, and 1997, respectively. Annualized return on
average assets and average equity were .90% and 9.7%, respectively for 1999
compared to 1.07% and 10.6% for 1998 and 1.16% and 11.8% for 1997.


     NET INTEREST INCOME. Net interest income represents the primary component
of the bank's earnings. It is the difference between interest and fee income
related to earning assets and interest expense incurred to carry
interest-bearing liabilities. Net interest income is impacted by changes in the
volume and mix of interest earning assets and interest bearing liabilities, as
well as by changing interest rates. In order to manage these changes, their
impact on net interest income and the risk associated with them, the bank
utilizes an ongoing asset/liability management program. This program includes
analysis of the difference between rate sensitive assets and rate sensitive
liabilities, earnings sensitivity to rate changes, and source and use of funds.
A discussion of net interest income and the factors impacting it is presented
below.

                                       30
<PAGE>   37

     Net interest income in 1999 increased by $276,000 or 5.4% over 1998.
Interest income in 1999 increased by $702,000 or 7.6% compared to 1998, while
interest expense increased by $426,000 or 10.2% during 1999 as compared to 1998.
Interest income increased during 1999 compared to 1998 as a result of an
increase in the average balance of loans and investment securities, which more
than offset the decrease in the average rates earned thereon. Interest expense
increased during 1999 compared to 1998 as a result of an increase in the average
balance of time deposits.

     Net interest income in 1998 increased by $241,000 or 5.0% over 1997.
Interest income in 1998 increased by $592,000 or 6.9% compared to 1997, while
interest expense increased by $351,000 or 9.2% during 1998 as compared to 1997.
Interest income increased during 1998 compared to 1997 as a result of an
increase in the average balance of loans and investment securities. Interest
expense increased during 1999 compared to 1998 as a result of an increase in the
average balance of time deposits and the average cost of funds paid on deposits.
During both 1999 and 1998, the bank used funds generated from deposit account
growth to fund loan commitments and to increase the average balance of
investment securities.

     The net interest margin is impacted by the change in the spread between
yields on earning assets and rates paid on interest bearing liabilities. Net
interest margin declined slightly from 1997 to 1999. See Table 2 -- Distribution
of Assets, Liabilities and Shareholders' Equity; Interest Rates and Interest
Differential.

(1) Yields are expressed on a tax equivalent basis using a 34% tax rate.

(2) For the purpose of these computations, nonaccruing loans are included in the
    amounts of average loans outstanding.

(3) Net interest spread is the difference between the ratios (expressed as a
    percentage) of taxable equivalent interest income to earnings assets and of
    interest expense to interest-bearing liabilities.

     Table 3 sets forth a summary of the changes in interest earned and interest
expense detailing the amounts attributable to (i) changes in volume (change in
average volume times the prior year's average rate), (ii) changes in rate
(change in the average rate times the prior year's average volume). The changes
in rate/volume (change in the average volume times the change in the average
rate), has been allocated to the changes in volume and changes in rate in
proportion to the relationship of the absolute dollar amounts of the change in
each. During 1999, net interest income increased $327,000 due to changes in
volume and decreased $582,000 due to changes in interest rates. In 1998, net
interest income increased $145,000 due to changes in volume and increased
$77,000 due to changes in interest rates.

     Another method of analyzing the change in net interest income is to examine
the changes between interest rate spread and the net interest margin on earning
assets. The interest rate spread as shown in Table 4 is the difference between
the average rate earned on earning assets and the average rate on interest
bearing liabilities. The net interest margin takes into account the benefit
derived from assets funded by interest free sources such as non-interest bearing
demand deposits and capital.

     The following discussion analyzes changes in Citizens National Bank's
spreads and margins in terms of basis points. A basis point is a unit of measure
for interest rates equal to .01%. One hundred basis points equals 1%.

     Interest rate spread decreased 24 basis points in 1999 while the net
interest margin declined 26 basis points. Both the interest rate spread and
margin were negatively impacted by a 28 basis point decline in earning asset
yields and offset by a 4 basis point decline in interest bearing liability
costs. Loan yields declined 39 basis points despite three separate increases in
the prime rate during 1999. The competitive environment for higher quality loans
required us to make such loans with rates and related loan fees lower that those
realized in prior years. The yield on securities available for sale declined 12
basis points. The reduction in liability costs is primarily the result of lower
rates on interest bearing checking, savings and money market accounts during the
year.

     Interest rate spread decreased 4 basis points in 1998. Earning asset yields
increased 5 basis points while funding costs increased 9 basis points. The net
interest margin declined from 4.26% in 1997 to 4.21% in 1998. The primary factor
in the decline in the interest margin and spread was the 13 basis point increase
in time deposit yields and 26 basis point increase in money market deposit
yields in 1998. These increases were due to the introduction of a new higher
yielding certificate of deposit product and the restructuring of the money
market deposit rates. These increases were partially offset by decreases in
yields on savings and money market accounts. Loan yields remained unchanged
during 1998 while yields on securities increased 5 basis points primarily due to
a larger investment in higher yielding callable agencies.

     PROVISION FOR LOAN LOSSES. The amount charged to provision for loan losses
is based on management's evaluation of the loan portfolio. Management determines
the adequacy of the allowance for loan losses based on past loan loss
experience, current economic conditions, composition of the loan portfolio, and
the anticipated potential for future loss. See Nonperforming Loans and Allowance
for Loan Losses for a comprehensive analysis.

     NONINTEREST INCOME. Noninterest income increased $149,000 or 36.0% during
1999 over the prior comparable period. The increase in 1999 was primarily due to
increased service charges on deposit accounts, insurance commissions, debit card
fees, and trust fees. These increases were offset by decreases in gains on sale
of other real estate owned and net gains on sale of securities. Trust assets
under management reached $20.3 million at December 31,1999, a 24.5% increase
from $16.3 million at December 31, 1998.

     Noninterest income increased $111,000 or 36.5% during 1998 over 1997. The
increase was due primarily to increased service charges on deposit accounts,
debit card fees, insurance income and net gains on sale of securities.

     NONINTEREST EXPENSES. Noninterest expenses increased $581,000 or 17.2%
during 1999 over the prior comparable period. The increase was primarily due to
an increase in salaries and employee benefits and other operating expenses.
Other operating expenses, which increased, were data processing expense, postage
expense, advertising expense and professional fees.

     Noninterest expenses increased $364,000 or 12.1% during 1998 over the prior
comparable period. The increase was primarily due to an increase in salaries and
employee benefits and other operating expenses. Other operating expenses, which
increased, were data processing, stationery and supplies, postage, telephone and
ATM expense.

                                       34
<PAGE>   41

     The opening of an additional branch in Hedgesville in October 1998 and the
start-up of the insurance subsidiary in November, 1998 caused salaries and
benefits and other operating expenses to increase somewhat in 1998 over 1997 and
to increase to a greater degree in 1999 over 1998.

     INCOME TAXES. The bank's provision for income tax totaled $621,000 in 1999,
$618,000 in 1998 and $636,000 in 1997. The effective tax rate was 33.7% in 1999
compared to 32.2% and 32.6% in 1998 and 1997, respectively. Lower tax exempt
earnings on investment securities was the primary reason for the increase in the
effective tax rate. See Note 13 of the Notes to Consolidated Financial
Statements for a comprehensive analysis of income tax expense.

     FINANCIAL CONDITION. Table 5 examines Citizens National's financial
condition in terms of its sources and uses of funds. Average funding uses
increased $12.4 million or 10.8% in 1999 compared with an increase of $6.6
million or 6.1% in 1998.

million from December 31, 1998, to December 31, 1999, completely due to the
increase in deposits. Shareholders' equity decreased $270,000 to $12.2 million
at December 31,1999, primarily

due to cash dividends of $458,000 and $1.0 million decrease in accumulated other
comprehensive income, offset by net income of $1.2 million. The decrease in
accumulated other comprehensive income was due to the unrealized market value
decline of the available for sale investment security portfolio.

     LOAN PORTFOLIO. At December 31,1999, total loans increased $11.9 million or
13.9% to $97.1 million from $85.3 million at December 31, 1998. Table 6 presents
major classifications of loans receivable at December 31, 1999, 1998 and 1997.
Table 7 presents loan maturities and interest sensitivity for certain loan
classifications at December 31, 1999. The loan mix did not change in any
material respect compared with December 31, 1999. The loan portfolio increase is
the result of developing new real estate loan programs and efforts to develop
new commercial and indirect lending relationships in the bank's expanded market
area of Berkeley County, West Virginia. The bank's management believes
additional growth in all lending areas is possible into year 2000. Management's
intent is to control the loan volume in a manner which would produce a loan to
deposit ratio between 75% and 80% and maintain credit quality. Such efforts were
successful as the loan to deposit ratio was 78.9% at December 31, 1999, and
74.9% at December 31, 1998. The ratio of net charge-offs to average loans
outstanding was .10% in 1999 and .11% in 1998.

     The loan portfolio classifications of installment and commercial real
estate did not change significantly in 1999 and 1998. Growth recorded in the
commercial loan area resulted in increases of 34.6% to $5.2 million outstanding
at December 31, 1999, and 39% to $3.9 million outstanding December 31, 1998.
These increases in commercial lending is primarily the result of efforts to
develop new relationships with commercial entities in the area. The bank's
market area was expanded to Berkeley County, West Virginia in 1998 which
provides a much larger area for commercial lending. The bank's management feels
additional growth in the commercial area is possible in 2000.

     Real estate mortgage loans comprised mainly of single-family one to four
family residences continued to be the bank's dominant loan category. Mortgage
lending comprises approximately 63% or $61.6 million of the total loan portfolio
at December 31, 1999, compared to 64% or $55.4 million at December 31, 1998.

     Demand for the bank's primary mortgage products, variable rate loans
carrying annual interest rate adjustments based on one, three and five year
Treasury rates continues to increase. The bank is beginning to see an increase
in the demand for fixed rate mortgage products, and for all loan products, as
the bank enters the Berkeley County, West Virginia real estate market. As of
December 31, 1999, 68% of the bank's mortgage loans were in adjustable rate
loans and 32% were fixed rate loans. Currently, the bank has approximately $1.7
million in fixed rate loans in the portfolio which were originated under terms
that would allow them to be sold on the secondary market.

     Additional information on the composition of the loan portfolio may be
found in Note 4 of the Notes to the Consolidated Financial Statements.

     Bank policy requires those loans which are past due 90 days or more be
placed on nonaccrual status unless they are both well secured and in the process
of collection. As of December 31, 1999 and 1998, nonaccrual loans approximated
 .02% and .32% of total loans (net), respectively.

     NONPERFORMING LOANS AND ALLOWANCE FOR LOAN LOSSES. Nonperforming loans
consist of loans in nonaccrual status, loans which are past due 90 days or more
and still accruing interest and restructured loans. As of December 31, 1999,
management is not aware of any potential problem loans other than those which
are on nonaccrual status or past due 90 days or more and still accruing
interest. Table 8 sets forth the amounts of such loans as of the dates
indicated.

Allowance for loan losses/Total loans...................  1.18%   1.32%   1.27%
</TABLE>

     All losses which may be reasonably anticipated are accounted for in the
allowance for loan losses. Management makes this determination quarterly by its
analysis of overall loan quality, changes in the mix and size of the loan
portfolio, previous loss experience, general economic conditions, information
about specific borrowers and other factors. The bank has no loans which are
considered to be impaired as of December 31, 1999 and 1998. At December 31, 1999
and 1998, the allowance for loan losses totaled $1.1 million. The allowance for
loan losses as a percentage of loans was 1.17% and 1.30% as of December 31, 1999
and 1998. The provision for loan losses exceeded net charge-offs by $26,000 and
$104,000 in 1999 and 1998. An analysis of the allowance for loan losses for the
years ended December 31, 1999 and 1998 may be found in Note 4 of the Notes to
the Consolidated Financial Statements and Table 9.

     The provision for loan losses is a charge to earnings which is made to
maintain the allowance for loan losses at a sufficient level. In 1999, 1998 and
1997, the provision totaled $118,000, $196,000 and $174,000, respectively. While
loan quality remains good and, as noted previously, past due and nonaccrual
loans are minimal, management decreased the provision for loan losses in 1999
based on the OCC's recommendation to management. Having thus decreased the
provision for loan losses, management believes the allowance for loan losses to
be adequate and is not aware of any information relating to the loan portfolio
which it expects will materially impact future operating results, liquidity or
capital resources. In addition, federal regulators may require additional
reserves as a result of their examination of the bank. The allowance for loan
losses reflects what management currently believes is an adequate level of
allowance, although there can be no assurance that future losses will not exceed
the estimated amounts, thereby adversely affecting future results of operations.

</TABLE>

     SECURITIES PORTFOLIO AND FEDERAL FUNDS SOLD. The bank's securities
portfolio consists of only available for sale securities. Classifying the
securities portfolio as available for sale provides management with increased
ability to manage the balance sheet structure and address asset/liability
management issues when needed. The fair value of the investment portfolio has
decreased $2.4 million to $31.2 million at December 31, 1999 from 1998.

     The composition of the portfolio continues to reflect the bank's
conservative philosophy which places greater importance on safety and liquidity
than on yield. At December 31, 1999, approximately 92.8% of the portfolio is
comprised of US Treasury and Agency securities and 6.8% in State and Political
Subdivision securities. The term to maturity is limited to seven years for
treasury and agency bonds and 10 years for municipal bonds. Typically,
investments in agency bonds contain a call feature. These bonds generally have a

                                       39
<PAGE>   46

somewhat higher yield. The average term to maturity of the portfolio as of
December 31, 1999 was 5.5 years.

     The bank generally participates in the overnight federal funds sold market.
Depending upon specific investing or funding strategies and/or normal
fluctuations in loan and deposit balances, the bank may need, on occasion, to
purchase funds on an overnight basis. At December 31, 1999, the bank had no
federal funds sold. In 1999 and 1998, the average balance in federal funds sold
was $1.2 million and $2.0 million, respectively.

     DEPOSITS AND OTHER FUNDING SOURCES. Total deposits were $124.5 million at
December 31, 1999, an increase of $9.2 million or 8.0% of deposits at December
31, 1998. Average deposits, however, showed a $13.5 million, or 12.5% growth, to
$120.9 million in 1999. The growth is partially due to the bank entering an
expanded market into Berkeley County, West Virginia with the opening of the
Hedgesville Branch. Deposits at the Hedgesville Branch totaled $12.8 million at
December 31, 1999, an increase of $9.0 million over December 31, 1998.

     Noninterest bearing deposits also grew by $1.7 million or 12.1%, during
1999 from $14.0 million at December 31, 1998, to $15.7 million at December 31,
1999. At December 31, 1999, noninterest bearing deposits represented 12.6% of
total deposits compared to 12.1% for 1998. Average noninterest bearing deposits
increased 22.8% from $12.2 million in 1998 to $14.9 million in 1999. The bank
has been promoting a new noninterest bearing deposit account with no minimum
balance and check truncation. Some growth has occurred in the noninterest
bearing deposit category, but a shift of dollars from other noninterest bearing
accounts to the no minimum balance account has also occurred.

     Interest bearing deposits increased by $7.5 million or 7.4% to $108.9
million at December 31, 1999. Interest bearing checking decreased by $160,000 in
1999. Included in this category are NOW accounts and Money Market Accounts.
Savings accounts decreased $679,000 in 1999 over the previous year to $16.4
million while the average savings deposits fell $141,000 or .81% to $17.3
million at December 31, 1999. The bank's largest source of interest bearing
funds is certificates of deposit. These accounts totaled $69.5 million at
December 31, 1999, an increase of $8.3 million or 13.7%. While the certificate
of deposit accounts increased, the composition of the portfolio also changed.
Certificates of deposit with a term of one year or less fell by $384,000 while
certificates of deposit that mature beyond one year (includes 36-month Ultimate
CD) increased by $1.3 million. Certificates of deposit over $100,000 increased
by $8.1 million or 81.2% in 1999. The 36-month Ultimate CD is a product which
allows the customer to withdraw all or a portion of the CD on the first or
second year anniversary date without penalty. Deposits may also be made to this
CD at any time. This CD has become very popular and was used in the grand
opening promotion for the Hedgesville Branch. Much of the increase in
certificates of deposit that mature beyond one year was into the 36-month
Ultimate CD. A large portion of the increase in certificates of deposit over
$100,000 is due to the customers depositing money into their 36-month Ultimate
CD putting the balance over $100,000.

     The following is a summary of the maturity distribution of certificates of
deposit in amounts of $100,000 or more as of December 31, 1999:

     CAPITAL RESOURCES. The bank is and has been well capitalized. Total
shareholders' equity at December 31, 1999 of $12.2 million represents 8.8% of
total assets. This compares to $12.5 million or 9.7%, at December 31, 1998.
Included in capital at December 31, 1999 are $892,000 of unrealized losses on
available for sale securities, net of deferred income taxes. At December 31,
1998, the bank had unrealized gains on available for sale securities, net of
deferred income taxes of $140,000. Such unrealized gains and losses are recorded
net of related deferred taxes and are primarily a function of available market
interest rates relative to the yield being generated on the available for sale
portfolio. No earnings impact results, however, unless the securities are
actually sold.

     Although not heavily traded, information available to management indicates
the market value of the bank's stock traded during 1999 in a range from $100.00
to $150.00 per share. During 1998, the market value of the bank's stock ranged
from $75.00 immediately after the two for one stock split effected as a 100%
stock dividend in March 1998 to $90.00 per share in December 1998. Book value
per share decreased from $54.66 at December 31, 1998 to $53.48 at December 31,
1999. Dividends, which are declared by the board of directors semiannually,
remained stable at $2.00 per share for 1999 and 1998. All per share amounts have
been restated to reflect the stock split in March 1998, except for market
values.

     The Federal Reserve's risk-based capital guidelines provide for the
relative weighting of both on-balance-sheet and off-balance-sheet items based on
their degree of risk. The bank continues to exceed all regulatory capital
requirements, and is unaware of any trends or uncertainties, nor do any plans
exist, which may materially impair or alter its capital position.

operating and capital ratios for the periods indicated.

     LIQUIDITY AND INTEREST RATE SENSITIVITY. The objective of the bank's
liquidity management program is to ensure the continuous availability of funds
to meet the withdrawal demands of depositors and the credit needs of borrowers.
The basis of the bank's liquidity comes from the stability of its core deposits.
Liquidity is also available through the available

                                       41
<PAGE>   48

for sale securities portfolio and short-term funds such as federal funds sold.
At December 31, 1999, these sources totaled $31.2 million, or 22.5% of total
assets. In addition, liquidity may be generated through loan repayments and over
$6.0 million of available borrowing arrangements with correspondent banks. At
December 31, 1999, management considered the bank's ability to satisfy its
anticipated liquidity needs over the next 12 months. Management believes that
the bank is well positioned and has ample liquidity to satisfy these needs.
Details on both the sources and uses of cash are presented in the Consolidated
Statements of Cash Flows contained in the financial statements.

     The objective of the bank's interest rate sensitivity management program,
also known as asset/liability management, is to maximize net interest income
while minimizing the risk of adverse effects from changing interest rates. This
is done by controlling the mix and maturities of interest sensitive assets and
liabilities. The bank has established an asset/liability committee for this
purpose.

     One common interest rate risk measure is the gap, or the difference between
rate sensitive assets and rate sensitive liabilities. A positive gap occurs when
rate sensitive assets exceed rate sensitive liabilities. This tends to be
beneficial in rising interest rate environments. A negative gap refers to the
opposite situation and tends to be beneficial in declining interest rate
environments. However, the gap does not consider future changes in the volume of
rate sensitive assets or liabilities or the possibility that interest rates of
various products may not change by the same amount or at the same time. In
addition, certain assumptions must be made in constructing the gap. For example,
the bank considers administered rate deposits, such as savings accounts, to be
immediately rate sensitive although their rate sensitivity could differ from
this assumption. The bank monitors its gap on a quarterly basis. Table 13
presents an interest sensitivity analysis of the bank's assets and liabilities
at December 31, 1999.

     IMPACT OF INFLATION. The results of operations and financial position of
the bank have been presented based on historical cost, unadjusted for the
effects of inflation, except for the recording of unrealized gains and losses on
securities available for sale. Inflation could significantly impact the value of
the bank's interest rate sensitive assets and liabilities and the cost of
noninterest expenses, such as salaries, benefits and other operating expenses.
Management of the money supply by the Federal Reserve to control the rate of
inflation may have an impact on the earnings of the bank. Further, changes in
interest rates to control inflation may have a corresponding impact on the
ability of certain borrowers to repay loans granted by the bank.

     As a financial intermediary, the bank holds a high percentage of interest
rate sensitive assets and liabilities. Consequently, the estimated fair value of
a significant portion of the bank's assets and liabilities change more
frequently than those of non-banking entities. The bank's policies attempt to
structure its mix of financial instruments and manage its interest rate
sensitivity in order to minimize the potential adverse effects of market forces
on its net interest income, earnings and capital. A comparison of the carrying
value of the bank's financial instruments to their estimated fair value as of
December 31, 1999 and December 31, 1998 is disclosed in Note 18 of the Notes to
the Consolidated Financial Statements.

                          INDEPENDENT AUDITOR'S REPORT

Shareholders and Board of Directors
Citizens National Bank of Berkeley Springs and Subsidiary
Berkeley Springs, West Virginia

     We have audited the accompanying consolidated statements of financial
condition of the Citizens National Bank of Berkeley Springs and Subsidiary as of
December 31, 1999 and 1998, and the related consolidated statements of income,
changes in shareholders' equity, and cash flows for each of the three years in
the period ended December 31, 1999. 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 consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Citizens
National Bank of Berkeley Springs and Subsidiary as of December 31, 1999 and
1998, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1999 in conformity with generally
accepted accounting principles.

           CITIZENS NATIONAL BANK OF BERKELEY SPRINGS AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  NATURE OF OPERATIONS:

     Citizens National Bank of Berkeley Springs provides a variety of banking
services to individuals and businesses through its two locations in Berkeley
Springs, West Virginia and its branch in Hedgesville, West Virginia which opened
in October 1998. Its primary deposit products are demand deposits and
certificates of deposit, and its primary lending products are commercial
business, real estate mortgage, and installment loans.

     CNB Insurance Services, Inc., wholly owned subsidiary of Citizens National
Bank, (collectively referred to as "the bank"), began operations in November,
1998. CNB Insurance Services, Inc. is a property and casualty insurance agency
selling primarily personal lines of insurance in Morgan and Berkeley Counties.

     The accounting policies of the Bank conform to generally accepted
accounting principles and to general practices of the banking industry.

  PRINCIPLES OF CONSOLIDATION:

     The consolidated financial statements include the accounts of Citizens
National Bank of Berkeley Springs and its wholly owned subsidiary. All
significant intercompany transactions and balances have been eliminated.

  USE OF ESTIMATES:

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

  SECURITIES AND MORTGAGE-BACKED SECURITIES:

     The Bank classifies and accounts for investments in equity securities that
have readily determinable fair values and for all investments in debt securities
as follows:

     a. Debt securities that the Bank has the positive intent and ability to
        hold to maturity are classified as held-to-maturity securities and
        reported at amortized cost.

     b. Debt and equity securities that are bought and held principally for the
        purpose of selling them in the near term are classified as trading
        securities and reported at fair value, with unrealized gains and losses
        included in earnings.

     c. Debt and equity securities not classified as either held-to-maturity
        securities or trading securities are classified as available-for-sale
        securities and reported at fair value, with unrealized gains and losses
        excluded from earnings and reported in a separate component of
        shareholders' equity as accumulated other comprehensive income.

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     Premiums and discounts are recognized in interest income using the interest
method over the period to maturity.

     Gain or loss on sale of securities is based on specific identification
method.

  IMPAIRED LOANS:

     Impaired loans are defined as those loans for which it is probable that
contractual amounts due will not be received. Statement of Financial Accounting
Standards (SFAS) No. 114, "Accounting by Creditors for Impairment of a Loan," as
amended by SFAS No. 118, requires that the measurement of impaired loans is
based on the present value of expected future cash flows discounted at the
historical effective interest rate, except that all collateral-dependent loans
are measured for impairment based on the fair value of the collateral. Larger
groups of small-balance loans such as residential mortgage and installment loans
that are considered to be part of homogeneous loan pools are aggregated for the
purpose of measuring impairment, and therefore, are not subject to these
statements. Management has established a dollar-value threshold for commercial
loans. The larger commercial loans are evaluated in accordance with the
statements. The Bank has no loans which are considered to be impaired at
December 31, 1999 and 1998.

  ALLOWANCE FOR LOAN LOSSES:

     The allowance for loan losses is maintained at a level which, in
management's judgment, is adequate to absorb credit losses inherent in the loan
portfolio. The amount of the allowance is based on management's evaluation of
the collectibility of the loan portfolio, including the nature of the portfolio,
credit concentrations, trends in historical loss experience, specific impaired
loans, and economic conditions.

     Allowances for impaired loans are generally determined based on collateral
values or the present value of estimated cash flows. The allowance is increased
by a provision for loan losses, which is charged to expense and reduced by
charge-offs, net of recoveries. Changes in the allowance relating to impaired
loans are charged or credited to the provision for loan losses. Because of
uncertainties inherent in the estimation process, management's estimate of
credit losses inherent in the loan portfolio and the related allowance may
change in the near term.

  LOANS HELD FOR SALE:

     The Bank underwrites certain loan originations in a manner so they are
eligible for sale in the secondary market. If mortgage loans are originated and
held for sale to investors they are classified as held for sale and recorded at
the lower of cost or market value. Gains and losses realized from the sale of
loans and adjustments to market value are included in non-interest income. The
Bank has from time to time sold mortgage loans to the Federal Home Loan Mortgage
Corporation (Freddie Mac) and other commercial banks.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  INTANGIBLE ASSETS:

     The intangible asset represents the acquisition in November 1998 by CNB
Insurance Services, Inc. of a customer list, contracts and records in the amount
of $116,000. The intangible asset is being amortized over fifteen years on a
straight line basis.

  LOAN SERVICING:

     The cost of mortgage servicing rights is amortized in proportion to, and
over the period of, estimated net servicing revenues. Impairment of mortgage
servicing rights is assessed based on the fair value of those rights. Fair
values are estimated using discounted cash flows based on a current market
interest rate. For purposes of measuring impairment, the rights are stratified
based on the predominant risk characteristics of the underlying loans: product
type, investor type, interest rate, term and geographic location. An analysis of
the risk characteristics of the Bank's loan servicing portfolio allows for all
loans to be defined by one risk category.

  INTEREST INCOME ON LOANS:

     Interest on loans is accrued and credited to income based on the principal
amount outstanding. The accrual of interest on loans is discontinued when, in
the opinion of management, there is an indication that the borrower may be
unable to meet payments as they become due. Upon such discontinuance, all unpaid
accrued interest is reversed.

  NONPERFORMING/NONACCRUAL ASSETS:

     Nonperforming/nonaccrual assets consist of loans on which interest is no
longer accrued, loans which have been restructured in order to allow the
borrower the ability to maintain control of the collateral, real estate acquired
by foreclosure and real estate upon which deeds in lieu of foreclosure have been
accepted. Interest previously accrued but not collected on nonaccrual loans is
reversed against current income when a loan is placed on a nonaccrual basis.

  LOANS RECEIVABLE:

     Loans receivable that management has the intent and ability to hold for the
foreseeable future or until maturity or payoff are reported at their outstanding
unpaid principal balances reduced by any charge-offs or specific valuation
accounts and net of any deferred fees or costs on originated loans, or
unamortized premiums or discounts on purchased loans.

  LOAN ORIGINATION FEES AND COSTS:

     Certain direct costs of originating loans are being capitalized and
amortized over the contractual life of the loan as an adjustment of the yield on
the related loan.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  PREMISES AND EQUIPMENT:

     Premises and equipment are carried at cost less accumulated depreciation.
Depreciation is calculated on both straight-line and accelerated methods over
the estimated useful lives of 15 to 50 years for buildings and 3 to 20 years for
equipment. Maintenance and repairs are charged to operating expenses as
incurred.

  INCOME TAXES:

     Deferred tax assets or liabilities are computed based on the difference
between the financial statement and income tax bases of assets and liabilities
using the enacted marginal tax rate. Deferred income tax expenses or credits are
based on the changes in the asset or liability from period to period.

  PENSION PLAN:

     The Bank's policy is to fund pension costs by annual contributions as
required by applicable regulations.

  CASH AND CASH EQUIVALENTS:

     For purposes of the Consolidated Statements of Cash Flows, the Bank has
defined cash and cash equivalents as all highly liquid debt instruments
purchased with a maturity of three months or less except for federal funds sold.
Those amounts are included in the balance sheet captions "Cash and Due From
Banks." The Bank has elected to present the net increase or decrease in loans
and time deposits in the Consolidated Statements of Cash Flows.

  EARNINGS AND DIVIDENDS PER SHARE:

     Earnings and dividends per share are computed on the basis of the weighted
average number of 229,024 shares of common stock outstanding during each year.

  OFF-BALANCE SHEET FINANCIAL INSTRUMENTS:

     In the ordinary course of business the Bank has entered into
off-balance-sheet financial instruments consisting of commitments to extend
credit, commercial lines of credit and letters of credit. Such financial
instruments are recorded in the financial statements when they become payable.

  POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS OTHER THAN PENSIONS:

     During the years that the employee renders the necessary service, the Bank
accrues the cost of providing postretirement health and life insurance benefits
to the employee.

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  FORECLOSED REAL ESTATE:

     Real estate properties acquired through, or in lieu of, loan foreclosure
are to be sold and are initially recorded at fair value at the date of
foreclosure establishing a new cost basis. After foreclosure, valuations are
periodically performed by management and the real estate is carried at the lower
of carrying amount or fair value less estimated cost to sell. Revenue and
expenses from operations and changes in the valuation allowance are included in
loss on foreclosed real estate. The historical average holding period for such
properties is twelve to eighteen months.

  TRUST FEES:

     Trust fees are recorded on the accrual basis.

  ADVERTISING COSTS:

     The Bank expenses advertising costs in the period in which they are
incurred. Advertising cost amounted to $82,459, $55,220 and $58,544 for the
years ended December 31, 1999, 1998 and 1997, respectively.

  COMPREHENSIVE INCOME:

     In 1998 the Bank adopted Statement of Financial Accounting Standards (SFAS)
No. 130 -- Reporting Comprehensive Income. Under SFAS No. 130, comprehensive
income is defined as the change in equity from transactions and other events
from nonowner sources. It includes all changes in equity except those resulting
from investments by shareholders and distributions to shareholders.
Comprehensive income includes net income and certain elements of "other
comprehensive income" such as foreign currency transactions; accounting for
futures contracts; employers accounting for pensions; and accounting for certain
investments in debt and equity securities.

     The Bank has elected to report its comprehensive income in the Consolidated
Statements of Changes in Shareholders' Equity. The only element of "other
comprehensive income" that the Bank has is the unrealized gain or losses on
available for sale securities. The 1997 financial statements have been
reclassified to reflect these changes in reporting format.

     Loans are placed on nonaccrual status when, in the judgement of management,
the probability of collection of interest is deemed to be insufficient to
warrant further accrual. A summary of nonaccrual loans is as follows:

     The contractual amount of interest that would have been recorded on
nonaccrual loans during 1999 and 1998 was $29,292 and $16,594, respectively. The
amount of interest income that was recorded on nonaccrual loans during 1999 and
1998 was $23,025 and $14,987, respectively.

     The Bank is not committed to lend additional funds to debtors whose loans
are nonperforming or on nonaccrual status.

NOTE 5.  LOAN SERVICING

     Mortgage loans serviced for others are not included in the accompanying
financial statements. The unpaid principal balances of mortgage loans serviced
for others was $6,189,932 and $7,655,856 at December 31, 1999 and 1998,
respectively.

     Custodial balances maintained in connection with the foregoing loan
servicing, and included in demand deposits, were $143,486 and $113,674 at
December 31, 1999 and 1998, respectively.

     Mortgage servicing rights of $12,253 were capitalized in 1998. The Bank did
not capitalize any mortgage servicing rights in 1999. An analysis of the
predominant risk characteristics indicates that there is not more that a normal
amount of prepayment risk and thus no write down is necessary. Amortization of
mortgage servicing rights was $2,258 and $2,439 in 1999 and 1998, respectively.
Mortgage servicing rights at the end of the years December 31, 1999 and 1998
were $36,370 and $38,472, respectively.

NOTE 12.  SHAREHOLDERS' EQUITY

     At a special meeting of the shareholders of the Bank on January 22, 1998,
the authorized shares of the Bank were increased from 125,000 shares to 600,000
shares. The increase in authorized shares was necessary to complete a proposed
stock dividend. The authorized but unissued shares may only be issued for the
purpose of declaring stock dividends to the Bank's shareholders.

     On January 22, 1998, the Board of Directors approved a stock split effected
in the form of a 100% stock dividend to shareholders of record on January 22,
1998. On March 1, 1998, the Bank distributed 114,512 shares of common stock to
shareholders in connection with the stock split effected in the form of a 100%
stock dividend. As a result of the stock dividend, common stock was increased by
$1,145,120 and retained income was decreased by $1,145,120.

     All references in the accompanying consolidated financial statements and
notes to per-share amounts have been restated to reflect the above stock split.
Earnings and dividends per share has been computed based on 229,024 weighted
average number of shares outstanding in 1999, 1998 and 1997.

     Generally accepted accounting principles require a valuation allowance
against deferred tax assets if, based on the weight of available evidence, it is
more likely than not that some or all of the deferred tax assets will not be
realized. The Bank believes that the deferred tax assets will be realized and
therefore no valuation allowance was established.

NOTE 15.  FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

     The Bank is a party to financial instruments with off-balance sheet risk in
the normal course of business to meet the financing need of its customers. These
financial instruments include commitments to extend credit, and standby letters
of credit. Those instruments involve, to varying degrees, elements of credit and
interest rate risk which are not reflected in

NOTE 15.  FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK (CONTINUED)
the statements of financial condition. The contractual amounts of those
instruments reflect the extent of involvement the Bank has in particular classes
of financial instruments.

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

     Commitments to extend credit are agreements to lend funds as long as there
is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses. Commercial
line of credit arrangements usually require payment of a fee.

     The Bank evaluates each customer's creditworthiness and related collateral
on a case-by-case basis. The amount of collateral obtained if deemed necessary
by the Bank upon extension of credit is based on management's credit evaluation
of the customer. Collateral held varies but may include accounts receivable,
inventory, real estate, equipment, and income-producing commercial properties.

     Standby letters of credit written are conditional commitments issued by the
Bank to guarantee the performance of a customer to a third party. Those
guarantees are issued to support public and private borrowing arrangements, bond
financing, and similar transactions. The credit risk involved in issuing a
letter of credit is essentially the same as that involved in extending loan
facilities to customers.

NOTE 16.  SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK

     The Bank's primary business is mortgage loans, which consists of
originating residential, construction, multi-family, and commercial real estate
loans and consumer and commercial loans. Citizen's National Bank's primary
lending area is Morgan County, West Virginia. Loans are occasionally made in
surrounding counties in West Virginia, Maryland and Virginia and Pennsylvania.

     The Bank evaluates each customer's creditworthiness on a case-by-case
basis. The amount of collateral obtained if deemed necessary by the Bank upon
the extension of credit is based on management's credit evaluation of the
customer. Collateral held varies but generally includes vehicles, equipment and
real estate.

NOTE 17.  REGULATORY MATTERS

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

     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios of total and Tier I
capital to risk-weighted assets (as defined), and of Tier I capital (as defined)
to average assets (as defined). Management believes, as of December 31, 1999,
that the Bank meets all capital adequacy requirements to which it is subject.

     As of December 31, 1999 and 1998, the most recent notification from the
Office of the Comptroller of the Currency categorized the Bank as well
capitalized under the regulatory framework for prompt corrective action. To be
categorized as well capitalized the Bank must maintain minimum total risk-based,
Tier I risk-based, and Tier I leverage ratios. There are no conditions or events
since that notification that management believes have changed the institution's
category.

     The Bank is subject to certain restrictions on the amount of dividends that
it may declare without prior regulatory approval.

NOTE 18.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair value of financial instruments is the amount at which the asset or
obligation could be exchanged in a current transaction between willing parties,
other than in a forced or liquidation sale. Fair value estimates are made at a
specific point in time based on relevant market information and information
about the financial instrument. These estimates do not reflect any premium or
discount that could result from offering for sale at one time the entire
holdings of a particular financial instrument. Because no market value exists
for a significant portion of the financial instruments, fair value estimates are
based on judgments regarding future expected loss experience, current economic
conditions, risk characteristics of various financial instruments, and other
factors. These estimates are subjective in nature, involve uncertainties and
matters of judgment and, therefore, cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

     Fair value estimates are based on financial instruments both on and off the
balance sheet without attempting to estimate the value of anticipated future
business, and the value of assets and liabilities that are not considered
financial instruments. Additionally, tax consequences related to the realization
of the unrealized gains and losses can have a potential effect on fair value
estimates and have not been considered in many of the estimates.

NOTE 18.  FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
     The following methods and assumptions were used to estimate the fair value
of significant financial instruments:

  FINANCIAL ASSETS:

     The carrying amounts of cash, due from banks and federal funds sold are
considered to approximate fair value. The fair value of investment securities,
including available for sale, are generally based on quoted market prices. The
fair value of loans is estimated using a combination of techniques, including
discounting estimated future cash flows and quoted market prices of similar
instruments where available.

  FINANCIAL LIABILITIES:

     The carrying amounts of deposit liabilities payable on demand are
considered to approximate fair value. For fixed maturity (time) deposits, fair
value is estimated by discounting estimated future cash flows using currently
offered rates for deposits of similar remaining maturities.

  OFF-BALANCE-SHEET-FINANCIAL INSTRUMENTS:

     The fair value of commitments to extend credit and standby letters of
credit is estimated using the fees currently charged to enter into similar
agreements.

     The estimated fair value of financial instruments at December 31, is
summarized as follows:

                    12 C.F.R. SECTIONS 215a(b), (c) AND (d)

(b) Dissenting shareholders

     If a merger shall be voted for at the called meetings by the necessary
majorities of the shareholders of each association or State bank participating
in the plan of merger, and thereafter the merger shall be approved by the
Comptroller, any shareholder of any association or State bank to be merged into
the receiving association who has voted against such merger at the meeting of
the association or bank of which he is a stockholder, or has given notice in
writing at or prior to such meeting to the presiding officer that he dissents
from the plan of merger, shall be entitled to receive the value of the share so
held by him when such merger shall be approved by the Comptroller upon written
request made to the receiving association at any time before thirty days after
the date of consummation of the merger, accompanied by the surrender of his
stock certificates.

(c) Valuation of shares

     The value of the shares of any dissenting shareholder shall be ascertained,
as of the effective date of the merger, by an appraisal made by a committee of
three persons, composed of (1) one selected by the vote of the holders of the
majority of the stock, the owners of which are entitled to payment in cash; (2)
one selected by the directors of the receiving association; and (3) one selected
by the two so selected. The valuation agreed upon by any two of the three
appraisers shall govern. If the value so fixed shall not be satisfactory to any
dissenting shareholder who has requested payment, that shareholder may, within
five days after being notified of the appraised value of his shares, appeal to
the Comptroller, who shall cause a reappraisal to be made which shall be final
and binding as to the value of the shares of the appellant.

(d) Application to shareholders of merging associations: appraisal by
    Comptroller; expenses of receiving association; sale and resale of shares;
    State appraisal and merger law

     If, within ninety days from the date of consummation of the merger, for any
reason one or more of the appraisers is not selected as herein provided, or the
appraisers fail to determine the value of such shares, the Comptroller shall
upon written request of any interested party cause an appraisal to be made which
shall be final and binding on all parties. The expenses of the Comptroller in
making the reappraisal or the appraisal, as the case may be, shall be paid by
the receiving association. The value of the shares ascertained shall be promptly
paid to the dissenting shareholders by the receiving association. The shares of
stock of the receiving association which would have been delivered to such
dissenting shareholders had they not requested payment shall be sold by the
receiving association at an advertised public auction, and the receiving
association shall have the right to purchase any of such shares at such public
auction, if it is the highest bidder therefor, for the purpose of reselling such
shares within thirty days thereafter to such person or persons and at such price
not less than par as its board of directors by resolution may determine. If the
shares are sold at public auction at a price greater than the amount paid to the
dissenting shareholders, the excess in such sale price shall be paid to such
dissenting shareholders. The appraisal of such shares of stock in any State bank
shall be determined in the manner prescribed by the law of the State in such
cases, rather than as provided in this section, if such provision is made in the
State law; and no such merger shall be in contravention of the law of the State
under which such bank is incorporated. The provisions of this subsection shall
apply only to shareholders of (and stock owned by them in) a bank or association
being merged into the receiving association.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     V.1.  INDEMNIFICATION:

          A. INDEMNIFICATION. Each person who was or is a party or is threatened
     to be made a party to or is involved (including, without limitation, as a
     witness or deponent) in any threatened, pending or completed action, suit
     or proceeding, whether civil, criminal, administrative, investigative or
     otherwise in nature ("Proceeding"), by reason of the fact that he or she,
     or a person of whom he or she is the legal representative, is or was a
     director or officer of the corporation or is or was serving at the written
     request of the corporation's Board of Directors, president or their
     delegate as a director, officer, employee or agent of another corporation,
     partnership, joint venture, trust or other enterprise, including service
     with respect to employee benefit plans, whether the basis of such
     Proceeding is alleged action or omission in an official capacity as a
     director, officer, trustee, employee or agent or in any other capacity,
     shall be indemnified and held harmless by the corporation to the fullest
     extent authorized by law, including but not limited to the West Virginia
     Code, as the same exists or may hereafter be amended (but, in the case of
     any such amendment, only to the extent that such amendment permits the
     corporation to provide broader indemnification rights than said Code
     permitted the corporation to provide prior to such amendment), against all
     expenses, liability and loss (including, without limitation, attorneys'
     fees and disbursements, judgments, fines, ERISA or other similar or
     dissimilar excise taxes or penalties and amounts paid or to be paid in
     settlement) incurred or suffered by such person in connection therewith;
     provided, however, that the corporation shall indemnify any such person
     seeking indemnity in connection with a Proceeding (or part thereof)
     initiated by such person only if such Proceeding (or part thereof) was
     authorized by the Board of Directors of the corporation; provided, further,
     that the corporation shall not indemnify any person for civil money
     penalties or other matters, to the extent such indemnification is
     specifically not permissible pursuant to federal or state statute or
     regulation, or order or rule of a regulatory agency of the federal or state
     government with authority to enter, make or promulgate such order or rule.
     Such right shall include the right to be paid by the corporation expenses,
     including, without limitation, attorneys' fees and disbursements, incurred
     in defending or participating in any such Proceeding in advance of its
     final disposition; provided, however, that the payment of such expenses in
     advance of the final disposition of such Proceeding shall be made only upon
     delivery to the corporation of an undertaking, by or on behalf of such
     director or officer, in which such director or officer agrees to repay all
     amounts so advanced if it should be ultimately determined that such person
     is not entitled to be indemnified under this Article or otherwise. The
     termination of any Proceeding by judgment, order, settlement, 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 which he reasonably believed to be in or not opposed to the best
     interest of the corporation, or that such person did have reasonable cause
     to believe that his conduct was unlawful.

                                      II-1
<PAGE>   100

          B. RIGHT OF CLAIMANT TO BRING SUIT. If a claim under this Article is
     not paid in full by the corporation within thirty days after a written
     claim therefor has been received by the corporation, the claimant may at
     any time thereafter bring suit against the corporation to recover the
     unpaid amount of the claim and, if successful, in whole or in part, the
     claimant shall be entitled to be paid also the expense of prosecuting such
     claim. It shall be a defense to any such action (other than an action
     brought to enforce a claim for expenses incurred in defending or
     participating in any Proceeding in advance of its final disposition where
     the required undertaking has been tendered to the corporation) that the
     claimant has not met the standards of conduct which make it permissible
     under the applicable law for the corporation to indemnify the claimant for
     the amount claimed, but the burden of proving such defense shall be on the
     corporation.

          Neither the failure of the corporation (including its Board of
     Directors, independent legal counsel, or its shareholders) to have made a
     determination prior to the commencement of such action that indemnification
     or reimbursement of the claimant is permitted in the circumstances because
     he or she has met the applicable standard of conduct, nor an actual
     determination by the corporation (including its Board of Directors,
     independent legal counsel, or its shareholders) that the claimant has not
     met such applicable standard of conduct, shall be a defense to the action
     or create a presumption that the claimant has not met the applicable
     standard of conduct.

          C. CONTRACTUAL RIGHTS: APPLICABILITY. The right to be indemnified or
     to the reimbursement or advancement of expenses pursuant hereto (i) is a
     contract right based upon good and valuable consideration, pursuant to
     which the person entitled thereto may bring suit as if the provisions
     hereof were set forth in a separate written contract between the
     corporation and the director or officer, (ii) is intended to be retroactive
     and shall be available with respect to events occurring prior to the
     adoption hereof, and (iii) shall continue to exist after the rescission or
     restrictive modification hereof with respect to events occurring prior
     thereto.

          D. REQUESTED SERVICE. Any director or officer of the corporation
     serving, in any capacity, (i) another corporation of which five percent
     (5%) or more of the shares entitled to vote in the election of its
     directors is held by the corporation, or (ii) any employee benefit plan of
     the corporation or of any corporation referred to in clause (i), shall be
     deemed to be doing so at the request of the corporation.

          E. NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any person
     hereunder shall not be exclusive of and shall be in addition to any other
     right which such person may have or may hereafter acquire under any
     statute, provision of the Certificate of Incorporation, Bylaws, agreement,
     vote of shareholders or disinterested directors or otherwise.

          F. INSURANCE. The corporation may purchase and maintain insurance, at
     its expense, to protect itself and any director, officer, employee or agent
     of the corporation or another corporation, partnership, joint venture,
     trust or other enterprise against such expense, liability or loss, whether
     or not the corporation would have the power to indemnify such person
     against such expense, liability or loss under West Virginia law.

     CNB Financial is a West Virginia corporation subject to the applicable
indemnification provisions of the General Corporation Law of West Virginia.

     The foregoing indemnity provisions have the effect of reducing directors'
and officers' exposure to personal liability for actions taken in connection
with their respective positions.

                                      II-2
<PAGE>   101

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

ITEM 22.  UNDERTAKINGS.

     (a)  CNB Financial hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:

               (i)    To include any prospectus required by section 10(a)(3) of
                      the Securities Act of 1933;

               (ii)   To reflect in the prospectus any facts or events arising
                      after the effective date of the registration statement (or
                      the most recent post-effective amendment thereof) which,
                      individually or in the aggregate, represent a fundamental
                      change in the information set forth in the registration
                      statement. Notwithstanding the foregoing, any increase or
                      decrease in volume of securities offered (if the total
                      dollar value of the securities offered would not exceed
                      that which was registered) and any deviation from the low
                      or high end of the estimated maximum offering range may be
                      reflected in the form of prospectus filed with the
                      Securities and Exchange Commission pursuant to Rule 424(b)
                      (sec. 230.424(b) of this chapter) if, in the aggregate,
                      the changes in volume and price represent no more than a
                      20% change in the maximum aggregate offering price set
                      forth in the "Calculation of the Registration Fee" table
                      in the effective registration statement;

               (iii)  To include any material information with respect to the
                      plan of distribution not previously disclosed in the
                      registration statement or any material change to such
                      information in the registration statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act of 1933, each such post-effective amendment shall
               be deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     (b)  CNB Financial 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), CNB Financial 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.

     (c)  CNB Financial undertakes that every prospectus: (i) that is filed
          pursuant to paragraph (b) immediately preceding, 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,

                                      II-4
<PAGE>   103

          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.

     (d)  The undertaking concerning indemnification is included as part of the
          response to Item 20.

     (e)  CNB Financial 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 or other equally prompt means. This includes
          information contained in documents filed subsequent to the effective
          date of the registration statement through the date of responding to
          the request.

     (f)  CNB Financial 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.
