law as well as the articles of incorporation and bylaws of Harleysville will
govern the rights of the former shareholders of Citizens. Differences exist in
the rights of shareholders of Citizens and of Harleysville. These differences
are due, in part, to the differences in the articles of incorporation and bylaws
of the entities as well as the differences in Pennsylvania corporate law and
Pennsylvania banking law. See "COMPARISON OF SHAREHOLDER RIGHTS" for disclosure
of the material differences in shareholder rights.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         Citizens and Harleysville structured the transaction to qualify as a
tax-free reorganization under the Internal Revenue Code of 1986. Under the
Internal Revenue Code, Citizens' shareholders will not recognize taxable gain or
loss upon the receipt of Harleysville common stock in exchange for Citizens
capital stock. Grant Thornton, LLP will provide an opinion, prior to the
completion of the merger, confirming these and certain other federal income tax
consequences of the merger. In addition, Grant Thornton has issued an opinion,
dated the date of this proxy statement/prospectus, attached for your review as
Annex B. You should consult with your own tax advisers regarding the tax
consequences of the merger in your particular circumstances. See, "APPROVAL OF
THE MERGER -- Federal Income Tax Consequences."

pooling of interests for financial reporting purposes. This means that we will

assuming the proposed merger is consummated, in accordance with Section 215a of
the National Bank Act, 12 U.S.C. Section 215a. The parties may terminate the
proposed merger if Citizens' shareholders exercise dissenters' rights with
respect to 277 or more shares of Citizens capital stock.

         If you do not follow the procedures in the statutory provisions of the
law, you may lose your dissenters' rights with respect to the merger. If you
sign and return your proxy without voting instructions, your proxy will be voted
in favor of the merger and you will lose any dissenters' rights that you have. A
copy of the applicable sections of the law is attached to this proxy
statement/prospectus as Annex C. We urge you to read carefully "APPROVAL OF THE
MERGER--Dissenters' Rights" and Annex C to this proxy statement/prospectus.

REQUIRED VOTE

         In order for the merger to occur, the shareholders of Citizens Bank and
Trust Company must approve the agreement. By approving the agreement,
shareholders are approving the merger. Approval of the merger requires the
affirmative vote of at least two-thirds (66.7%) of Citizens' outstanding
capital stock. On this date, the directors and officers of Citizens and persons
or entities that they control own 3,114 shares of Citizens capital stock, or
56.2% of the outstanding shares. Citizens expects them to vote these shares
"FOR" approval of the merger.

         Each share entitled to vote at the meeting is entitled to one vote. At
least a majority of the total number of shares of capital stock outstanding as
of February 11, 2000, will be necessary to have a quorum at the meeting. A
quorum is necessary so that actions taken at the meeting are valid. In addition
to voting to approve the merger, you may also be asked to vote on other matters
that may properly come before the meeting or any adjournments of the meeting.

REGULATORY APPROVALS

         The parties must file applications or notices to approve the merger
with certain banking regulatory agencies. These agencies are the Board of
Governors of the Federal Reserve System, the Office of the Comptroller of the
Currency and the Pennsylvania Department of Banking.

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

         Following the merger, the Board of Directors of Harleysville will be
the same persons who serve on the Board of Directors immediately before the
merger and James A. Wimmer. Harleysville will appoint Mr. Wimmer to its Board of
Directors to serve as a Class C Director. Subject to regulatory approval,
Citizens National Bank will appoint Mr. Wimmer and Linda P. Wimmer to its Board
of Directors. Mr. Wimmer currently is Chairman, President and a Director of
Citizens Bank and Trust Company. Mrs. Wimmer currently is a Director of
Citizens.

OPINION OF FINANCIAL ADVISOR

         Citizens' Board of Directors asked Tucker Anthony Cleary Gull, its
investment banking firm located at 2101 Oregon Pike, Lancaster, Pennsylvania
17601, to provide investment banking services in the merger. These services
included providing an opinion that the value of the Harleysville common stock to
be received by shareholders in the merger is fair, from a financial point of
view. The Board of Directors considered and approved the terms of the merger,
including the financial terms. Tucker Anthony did not approve the financial or
other terms of the merger. In writing its opinion Tucker Anthony considered
various factors, including Citizens' and Harleysville's operating results,
current financial condition and perceived future prospects.

proxy statement/prospectus as Annex D. You should read the opinion in its

considered by Tucker Anthony in rendering its opinion. See "APPROVAL OF THE
MERGER--Opinion of Financial Advisor."

         Citizens has agreed to pay Tucker Anthony a fee of 1.00% of the
aggregate consideration to be paid in the merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS

         Citizens' Board of Directors believes that the merger is in the best
interests of shareholders. The Board of Directors recommends that you vote "FOR"
approval of the merger.

                           COMPARATIVE PER SHARE DATA

GENERAL

         We summarize below the per share information for Harleysville and
Citizens Bank and Trust Company on a historical, pro forma combined and
equivalent basis. You should read this information in conjunction with
Harleysville's historical financial statements and the related notes contained
in the annual and quarterly reports and other documents filed by Harleysville
with the Commission. See "AVAILABLE INFORMATION." The Harleysville proforma
information gives effect to the merger, accounted for as pooling of interests,
assuming that 166 shares of Harleysville common stock are issued for each
outstanding share of Citizens' capital stock. Citizens' equivalent share amounts
are calculated by multiplying the pro forma basic and diluted earnings per
share, historical per share dividend and historical shareholders' equity by the
exchange ratio of 166 shares of Harleysville common stock so that the per share
amounts equal the respective values for one share of Citizens capital stock. Do
not rely on the pro forma information as indicative of the historical results
that we would have had if we had been combined or of the future results that we
will experience after the merger. Pro forma information does not include any
expense savings anticipated as a result of the merger or any one time merger
related expenses.

 MARKET VALUE OF SECURITIES AND PRO FORMA PRICE PER SHARE INFORMATION

         Citizens capital stock trades on a very limited basis in privately
negotiated transactions. Consequently, the stock prices in the table below may
not reflect fair market value. The last sale of Citizens capital stock with
respect to which Citizens was a party before public announcement of the
agreement and related merger was the purchase of 14 shares at $4,250 per share
on January 27, 1999.

          The last reported sale of Harleysville common stock before public
announcement of the agreement and related merger was a trade of 100 shares at
$31.94 per share on December 28, 1999. On December 28, 1999, the per share
closing price for Harleysville common stock was $31.94 as reported by the
NASDAQ. On December 31, 1999, the closing sale price of Harleysville common
stock was $32.50, making the value of 166 shares of Citizens capital stock equal
to $5,395, if the merger had taken place on that date.

         The pro forma equivalent price per share of common stock for each
company for December 31, 1999, has been calculated as if:

         -        The merger had taken place on December 31; and

         -        Shares of Citizens capital stock were exchanged for
                  Harleysville common stock at a rate of one share of Citizens
                  stock for 166 shares of Harleysville common stock.

         The pro forma equivalent per share closing bid and asked quotations as
of December 31, 1999, for each share of Citizens capital stock are $5,375 and
$5,395. The pro forma equivalent per share closing bid and asked quotations for
Citizens and Harleysville on December 31, 1999, are in the table, below.

(a)      The sales price reported involved a transaction pursuant to a
         repurchase program adopted by Citizens' Board of Directors. Citizens

         the sales price of its capital stock in transactions to which it is

         You should obtain current market quotations for Harleysville common
stock because the market price of the stock may fluctuate between the date of
this document and the date on which the merger is completed, and thereafter. You
can get these quotations from a newspaper, on the internet or by calling your
broker. Because the number of shares of Harleysville common stock that Citizens
shareholders will receive is fixed and because the market price of Harleysville
common stock may fluctuate, the value of the shares of Harleysville common stock
that Citizens shareholders will receive may increase or decrease before the
merger is completed. See, "INFORMATION ABOUT THE MERGER - Terms of the Merger."

                           THE MEETING
GENERAL

         The Board of Directors provides this proxy statement/prospectus to
Citizen's shareholders for a meeting that will be held at the main office of the
bank, 372 Delaware Avenue, Palmerton, Pennsylvania 18071, on Friday, April 7,
2000, at 10:00 a.m.

         At the meeting, Citizen's shareholders will consider and vote on:

               Approval and adoption of the agreement that provides for the
               merger; and

               Other matters that properly come before the meeting or any
               adjournments of the meeting.

         If shareholders approve the merger, Citizens Bank and Trust Company
will merge into Citizens National Bank, a subsidiary of Harleysville National
Corporation. When the merger is completed, Citizens Bank and Trust Company will
cease to exist and its shareholders will receive 166 shares of Harleysville
common stock in exchange for each share of capital stock that they hold. A vote
for approval of the agreement is a vote for the approval of the merger of
Citizens Bank and Trust Company into Citizens National Bank and for the exchange
of Citizens Bank and Trust Company capital stock for Harleysville common stock.

RECORD DATE, QUORUM, REQUIRED VOTE

         You can vote at the meeting if you owned Citizens capital stock at the
close of business on the record date, February 11, 2000. As of that date, there
were 5,542 shares of Citizens capital stock outstanding and entitled to vote.

         At least a majority of the total number of shares of Citizens Bank and
Trust Company capital stock outstanding on February 11, 2000 is required for a
quorum at the meeting. These shares may be represented by a shareholder in
person or by completing and returning the enclosed proxy.

         To complete the merger, at least two-thirds (66.7%) of the outstanding
shares of Citizens must vote to approve the merger.

VOTING, REVOCATION AND SOLICITATION OF PROXIES

         If you execute a proxy, you can revoke it at any time until after the
vote on the merger. Unless revoked, shares represented by proxies will be voted
at the meeting and at all adjournments or postponements of the meeting. Your
attendance at the meeting will not revoke your proxy. Proxies may be revoked by:

                                       17
<PAGE>   24
               Delivery of a notice of revocation or of a later-dated proxy to
               Thomas K. Thomas, Secretary, Citizens Bank and Trust Company, 372
               Delaware Avenue, Palmerton, Pennsylvania 18071; or

               Your attendance at the meeting and your notification to the
               Secretary that you wish to vote your shares in person.

         If a quorum is not present at the beginning of the meeting, the Board
of Directors of Citizens intends to adjourn the meeting to another place and
time without further notice to the shareholders. If for any other reason the
Board of Directors believes additional time should be allowed to obtain proxies,
the Board may adjourn the meeting with a vote of a majority of the shares
outstanding. If the Board proposes to adjourn the meeting, the persons named in
the enclosed proxy will vote all shares for which they have voting authority in
favor of the adjournment.

         The proxyholders will vote signed and returned proxies as instructed by
the shareholders. If no instructions are indicated, the proxyholders will vote
the proxies in favor of the merger and in favor of adjournment, if necessary. A
proxy also gives the persons named as proxyholders the right to vote on other
matters incidental to the conduct of the meeting. Although the Board of
Directors knows of no other business to be presented at the meeting, if any
other matters are properly brought before the meeting, any proxy given by you
will be voted in accordance with the recommendations of the Board of Directors
of Citizens. Proxies marked as abstentions will not be counted as votes cast.
Shares held by brokerage companies or in street names that have been designated
by brokers on proxy cards as not voted will not be counted as votes cast.
Proxies marked as abstentions or as broker no-votes:

               Will be treated as shares present for purposes of determining
               whether a quorum is present; and

               Will have the same effect as a vote against the merger.

         In connection with the solicitation of proxies, Citizens will:

               Bear the cost of soliciting proxies;

               Reimburse brokerage firms and other custodians, nominees and
               fiduciaries for their reasonable expenses; and

               If it so decides, solicit proxies personally or by telegraph or
               telephone.

VOTING SECURITIES AND SECURITIES OWNERSHIP

         Only those shareholders whose ownership appears on the shareholder
record of Citizens Bank and Trust Company on the record date are entitled to
vote at the meeting. Each share of Citizens' capital stock is entitled to one
vote. On February 14, 2000, there were 6,000 shares of capital stock authorized
and 5,542 shares of capital stock outstanding. Capital stock is Citizens' only
issued and outstanding class of stock. Except as shown on the table on page 56,
Citizens' Board of Directors is not aware of any individual, entity or group
that owns more than 10% of Citizens' capital stock.

                             APPROVAL OF THE MERGER

         In this section we describe the material terms and provisions of the
proposed merger. A copy of the agreement that provides for the merger is
attached to this proxy statement/prospectus as Annex A. This is only a
discussion of material terms of the merger and we qualify it in its entirety by
reference to the full text of the agreement. We urge all shareholders to read
the merger agreement.

         The agreement provides that:

          -    Citizens Bank and Trust Company will be merged into Citizens
               National Bank; and

               You, as a shareholder of Citizens Bank and Trust Company, will
               receive 166 shares of Harleysville common stock for each share of
               Citizens capital stock that you own when the merger is completed.

         Citizens Bank and Trust Company will cease to exist. Citizens National
Bank will be a subsidiary of Harleysville National Corporation. The Office of
the Comptroller of the Currency and the Federal Deposit Insurance Corporation
will continue to regulate Citizens National Bank.

         The Board of Directors has unanimously approved and adopted the
agreement and the merger and believes the merger is in the best interests of
Citizens, its shareholders and other constituencies. The Board of Directors of
Citizens Bank and Trust Company unanimously recommends that shareholders vote
"FOR" the agreement and related merger:

BACKGROUND OF THE MERGER, REASONS AND RECOMMENDATION OF THE BOARD OF DIRECTORS

Background of the Merger

         For many years the operating philosophy of the Citizens Board of
Directors has been to increase profitability while operating as an independent
community focused bank. In recent years this has become more difficult due to
increasingly competitive forces. Opportunities for Citizens

                                       19
<PAGE>   26
to increase profitability by shifting assets from lower yielding portfolio
investments to higher yielding loans has been limited because of economic and
demographic conditions in its traditional market areas. At the same time, the
expenses of continuing investments in upgrading and improving technology and the
need for additional financial services and products to keep pace with
competition, combined with its more limited economies of scale, place additional
pressures on Citizen's profitability.

         For some time James A. Wimmer, Citizen's Chairman and President, has
met periodically with representatives of Tucker Anthony Cleary Gull (formerly
Hopper Solliday & Co.) to discuss trends in the banking industry and the
strategic implications for Citizens. Due in large part to the circumstances
described in the preceding paragraph, Mr. Wimmer invited representatives of
Tucker Anthony to meet with the Citizens Board of Directors in March 1999. At
that time Tucker Anthony made a presentation regarding banking industry trends,
merger and acquisition activity in the banking industry and various strategic
options available to Citizens. Among the strategic options discussed was the
possibility that Citizens combine with another larger banking organization that
would have the size, financial and managerial resources, services and markets
capable of building long-term value for Citizens shareholders.

         At a May 1999 meeting of the Citizens Board of Directors, Tucker
Anthony was authorized to contact five banking institutions that Tucker Anthony
and the Board of Directors believed might have an interest in a business
combination with Citizens. Four of the five institutions expressed interest and,
in June 1999, each was provided with a confidential offering memorandum prepared
by Tucker Anthony describing Citizens.

         In July 1999, two written, non-binding indications of interest were
received by Tucker Anthony in response to the confidential offering memorandums
it distributed. Tucker Anthony reviewed both of the indications of interest with
the Citizens Board of Directors at a meeting on August 4, 1999. Legal counsel
also reviewed with the Board of Directors their fiduciary duties under current
law. The Board of Directors directed Tucker Anthony to ask both parties to
consider increasing the amount of consideration proposed in their respective
indications of interest and both did so. Consequently, both parties were invited
to make presentations to the Citizens Board of Directors and both did so on
August 25, 1999.

         After the presentations, the Board of Directors discussed the two
presentations, the pricing, structure and other proposals contained in the
respective indications of interest, the markets in which each of the parties
currently competes and the anticipated implications for Citizens' employees,
customers and communities if a business combination with each party were
consummated. In addition, Tucker Anthony compared and assessed the fairness of
the pricing proposals contained in the two indications of interest and compared
the financial condition, earnings and stock performance of the two parties.

         During September 1999, Tucker Anthony continued to explore with both
parties a possible business combination with Citizens.

                                       20
<PAGE>   27
         On October 6, 1999, Mr. Wimmer, Terry D. Eckert, a Citizen's Director,
a representative of Tucker Anthony and a representative from Citizen's
independent public accounting firm met with members of Harleysville's senior
management team to further discuss the possibility of a business combination
between Citizens and Harleysville. Immediately following that meeting, the
Citizens Board of Directors authorized Mr. Wimmer and Mr. Eckert, together with
legal counsel, the independent public accountants and Tucker Anthony, to enter
into detailed negotiations with Harleysville as to a business combination
between Citizens and Harleysville and to conduct due diligence with regard to
Harleysville and to permit Harleysville to conduct due diligence with regard to
Citizens. At that time, Tucker Anthony was directed to inform the other
institution that had expressed interest that Citizens was not interested in
further pursuing a business combination with that institution.

         Following the October 6, 1999 meeting, Mr. Wimmer and Mr. Eckert,
together with legal counsel, the independent public accountants and Tucker
Anthony, entered into detailed negotiations regarding the pricing, structure and
other issues associated with a business combination in which Citizens would
merge with Citizens National Bank, a subsidiary of Harleysville, and Citizens
shareholders would receive shares of Harleysville common stock in exchange for
their shares of Citizens capital stock. During this period, which included due
diligence investigations conducted by both parties, two face to face sessions
and numerous telephone conferences and correspondences, the exchange ratio for
the combination as well as other issues were determined on the basis of
arms-length negotiations. Other important elements of the negotiation included
representation of Citizens on the Harleysville and Citizens National Bank Boards
of Directors, dividends and treatment of Citizens employees. This negotiation
process resulted in the merger agreement attached hereto as Annex A.

         On December 28, 1999, the Board of Directors met to consider the merger
agreement. Tucker Anthony presented its written opinion as to the fairness of
the consideration provided to Citizens shareholders in connection with the
merger transaction with Harleysville. Legal counsel to Citizens conducted a
detailed review of the merger agreement and again reviewed with the Board of
Directors their fiduciary duties under current law. After discussion, the
Citizens Board unanimously approved the merger agreement and the merger
transaction with Harleysville as being in the best interests of Citizens, its
shareholders and other constituencies. The merger agreement was executed
immediately following the meeting.

Reasons for the Merger

         At its meeting on December 28, 1999, the Citizens Board of Directors
unanimously determined that the terms of the merger agreement and the merger
transaction with Harleysville were in the best interests of Citizens, its
shareholders and other constituencies. In making this determination, the Board
concluded, among other things, that the merger transaction with Harleysville was
superior to the other alternatives available to Citizens and to the prospects of
continuing to operate Citizens as an independent community focused bank.



                                       21
<PAGE>   28
         In the course of reaching its decision to approve the agreement, the
Citizens Board of Directors consulted with Tucker Anthony, its legal counsel and
independent certified public accountants. The Board considered, among other
things, the factors described above and the following:


          -    The opinion of Tucker Anthony that the consideration to be
               received by Citizens' shareholders was fair from a financial
               point of view;

          -    The Board's familiarity with and review of Citizens' business
               prospects and financial condition, including its future prospects
               were it to remain independent;

          -    The pressures of competition and the ability of Citizens,
               considering its limited economies of scale, to increase
               profitability while continuing to operate as an independent
               community focused bank;

          -    A determination that a business combination with Harleysville
               would expand Citizens' lending capabilities and significantly
               increase the range of financial products and services available
               to Citizens' customers;

          -    The prices, multiples of earnings per share and premiums over
               book value and market value paid in recent acquisitions of banks;

          -    The earnings, financial condition and future prospects of
               Harleysville;

          -    The historical market prices for shares of Harleysville common
               stock and historical price to earnings and price to book value
               trading multiples for such shares;

          -    The substantially greater liquidity of Harleysville common stock,
               which is publicly traded, compared to the relatively illiquid
               market for Citizens capital stock;

          -    Harleysville's agreement that James A. Wimmer, Citizens' Chairman
               and President, would be appointed to the Harleysville Board of
               Directors and that Mr. Wimmer and Linda P. Wimmer, his wife and a
               Director of Citizens, would be appointed to the Citizens National
               Bank Board of Directors;

          -    The business and prospects of Harleysville, including its prior
               experience acquiring banks, its existing presence in Citizens'
               traditional market areas, the economic vitality of the other
               market areas served by Harleysville and the opportunities
               presented by customer demand in those market areas;

          -    The experience of Harleysville's senior management team;

                                       22
<PAGE>   29
          -    The benefits of a tax-free to Citizens shareholders; and

          -    The alternative of Citizens remaining as an independent community
               focused bank or combining with other potential merger partners,
               as compared to the effect of Citizens combining with Harleysville
               and the determination that the merger transaction with
               Harleysville presented the best opportunity for maximizing
               long-term shareholder value and serving Citizens' other
               constituencies including, without limitation, its customers and
               the communities in which it is located.

         We do not intend the foregoing discussion of the information and
factors considered by the Citizens Board of Directors to be exhaustive but we
believe it includes all material factors considered by the Citizens Board of
Directors. In reaching its decision to approve and recommend the merger, the
Citizens Board of Directors did not assign any relative or specific weights to
the foregoing factors and individual Directors may have given differing weights
to different factors. After deliberating with respect to the merger transaction
with Harleysville, considering, among other things, the matters discussed above
and the opinion of Tucker Anthony referred to above, the Citizens Board of
Directors unanimously approved and adopted the merger agreement and the merger
transaction with Harleysville.

Recommendation of the Board of Directors

         The Board of Directors of Citizens believes that the terms of the
merger are fair to and in the best interests of Citizens, its shareholders and
other constituencies, and has approved the Agreement. The Board of Directors of
Citizens unanimously recommends that the shareholders of Citizens approve the
merger agreement.


                          OPINION OF FINANCIAL ADVISOR

         General. Pursuant to the engagement letter dated May 22, 1999, the
Citizens Bank and Trust Company Board of Directors retained Tucker Anthony to
render financial advisory and investment banking services to Citizens in
connection with the possible sale of Citizens to another financial institution.
Tucker Anthony has no other material relationship Citizens.

         Tucker Anthony is a regional investment banking firm and as a customary
part of its investment banking business is engaged in the valuation of bank and
bank holding company securities in connection with mergers, acquisitions,
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for various other purposes. As a specialist in
the securities of financial institutions, Tucker Anthony has experience in, and
knowledge of, the valuation of banking enterprises. The Citizens Board of
Directors selected Tucker Anthony on the basis of Tucker Anthony's ability to
evaluate the fairness of the merger from a financial point of view, its
qualifications, its previous experience and its reputation in the banking and
investment communities. Tucker Anthony has acted exclusively for the Citizens

                                       23
<PAGE>   30
Board of Directors in rendering its fairness opinion and will receive a fee from
Citizens for its services.

         Tucker Anthony has rendered a written opinion to the Citizens Board of
Directors, dated as of the date of this joint proxy statement/prospectus, to the
effect that, as of such date, the merger consideration is fair, from a financial
point of view, to the shareholders of Citizens. The full text of the Tucker
Anthony opinion is attached as Annex D to this proxy statement/prospectus and is
incorporated herein by reference. We urge Citizens shareholders to read the
Tucker Anthony opinion in its entirety for a description of the procedures
followed, assumptions made, matters considered, and qualifications and
limitations of Tucker Anthony's review. We qualify the following summary of the
opinion in its entirety by reference to the full text of the opinion. The merger
consideration was determined by negotiation between Harleysville and Citizens
and was not determined by Tucker Anthony. See "APPROVAL OF THE
MERGER--Background of the Merger."

         The Tucker Anthony opinion is directed only to the merger consideration
and is not a recommendation to any Citizens shareholder on how to vote at the
special meeting.

         In rendering its opinion, Tucker Anthony reviewed, among other things:

          -    Citizens' audited financial statements and related financial
               information for years ended December 31, 1994 through December
               31, 1998 and Citizens' quarterly financial statements for the
               periods ending March 31, 1999, June 30, 1999 and September 30,
               1999;

          -    Harleysville's Annual Reports on Form 10-K and related financial
               information for years ended December 31, 1994 through December
               31, 1998 and Quarterly Reports on Form 10-Q for the periods
               ending March 31, 1999, June 30, 1999 and September 30, 1999;

          -    certain information concerning the respective businesses,
               operations, regulatory condition and prospects of Harleysville
               and Citizens, including financial forecasts, relating to the
               business, earnings, assets and prospects of Harleysville and
               Citizens, furnished to Tucker Anthony by Harleysville and
               Citizens, which Tucker Anthony discussed with members of senior
               management of Harleysville and Citizens;

          -    historical market prices and trading activity for the
               Harleysville common stock and Citizens capital stock and similar
               data for certain publicly traded companies which Tucker Anthony
               deemed to be relevant;

          -    the results of operations of Harleysville and Citizens and
               similar data for certain companies which Tucker Anthony deemed to
               be relevant;

                                       24
<PAGE>   31
          -    the financial terms of the merger contemplated by the agreement
               and the financial terms of certain other mergers and acquisitions
               which Tucker Anthony deemed to be relevant;

          -    the pro forma impact of the merger on the earnings and book value
               per share, consolidated capitalization and certain balance sheet
               and profitability ratios of Harleysville;

          -    the agreement; and

          -    such other matters as Tucker Anthony deemed necessary.

         Tucker Anthony met with certain members of senior management and other
representatives of Harleysville and Citizens to discuss the foregoing as well as
other matters Tucker Anthony deemed relevant. Tucker Anthony considered
financial and other factors as it deemed appropriate under the circumstances and
took into account its assessment of general economic, market and financial
conditions, and its experience in similar transactions, as well as its
experience in securities valuation and its knowledge of the banking industry
generally. Tucker Anthony's opinions are necessarily based upon conditions as
they existed and could be evaluated on the respective dates thereof and the
information made available to Tucker Anthony through the respective dates
thereof.

         Tucker Anthony relied without independent verification upon the
accuracy and completeness of all of the financial and other information reviewed
by and discussed with it for purposes of its opinion. With respect to the
financial forecasts reviewed by Tucker Anthony in rendering its opinion, Tucker
Anthony assumed that the financial forecasts were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
managements of Citizens and Harleysville as to the future financial performance
of Citizens and Harleysville. Tucker Anthony did not make any independent
evaluation or appraisals of the assets or liabilities of Harleysville nor was it
furnished with any such appraisals. Tucker Anthony also assumed, without
independent verification, that the aggregate allowances for loan losses for
Citizens and Harleysville were adequate.

         The summary set forth below does not purport to be a complete
description of the analyses performed by Tucker Anthony in connection with the
merger. The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial analysis and the
application of these methods to the particular circumstances and, therefore, the
opinion is not readily susceptible to summary description. Tucker Anthony
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, could create an incomplete view of the
evaluation process underlying the opinion. No one of the analyses performed by
Tucker Anthony was assigned a greater significance with respect to industry
performance, business and economic conditions and other matters, many of which
are beyond

                                       25
<PAGE>   32
Citizens' or Harleysville's control. The analyses performed by Tucker Anthony
are not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by the analyses.
Additionally, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses actually may be sold.

         Transaction Summary. Tucker Anthony reviewed with the Citizens Board of
Directors the key financial terms of the proposed merger, including the expected
method of accounting, the exchange ratio, the share price of Harleysville as of
December 14, 1999, the resulting indicated value per share of Citizens capital
stock in the merger and the resulting indicated aggregate consideration to be
paid in the merger:

          -    The proposed method of accounting for the merger was a
               pooling-of-interests in a tax-free exchange;

          -    The indicated value was $5,374.25 per share of Citizens capital
               stock, determined by multiplying the exchange ratio by the
               closing price on the NASDAQ National Market of Harleysville
               common stock on December 14, 1999;

          -    The indicated aggregate consideration to be paid in the merger
               was $29.8 million based on 5,542 fully diluted shares of Citizens
               capital stock outstanding; and

          -    The $5,374.25 per share value represented 169% of Citizens'
               fully-diluted book value per share as of September 30, 1999 and a
               multiple of 21.3 times Citizens' net income for the twelve months
               ended September 30, 1999.

         Contribution Analysis. Tucker Anthony reviewed the contribution made by
each of Citizens and Harleysville to various balance sheet items and net income
of the combined company at the proposed exchange ratio based on balance sheet
data at September 30, 1999 and trailing twelve months earnings as of September
30, 1999. This analysis showed that:

          -    Citizens shareholders would own approximately 10.4% of the
               aggregate shares outstanding of the combined company;

          -    Citizens was contributing 7.6% of total assets of the combined
               company;

          -    Citizens was contributing 5.3% of total loans of the combined
               company;

          -    Citizens was contributing 8.4% of total deposits of the combined
               company;

          -    Citizens was contributing 12.0% of shareholders' equity of the
               combined company; and

                                       26
<PAGE>   33
          -    Citizens was contributing 6.0% of net income of the combined
               company.

         Summary Comparison of Selected Institutions - Citizens. Tucker Anthony
compared selected balance sheet data, asset quality, capitalization and
profitability ratios and market statistics using financial data at or for the
twelve months ended September 30, 1999 and market data as of December 14, 1999
for Citizens and market data as of December 14, 1999 for a group of Pennsylvania
banks and bank holding companies consisting of ten institutions with total
assets between $118.9 million and $192.2 million. The analysis included, but was
not limited to, the following ratios: loans/deposits, equity/assets,
non-performing assets/total assets, allowance for loan losses/ non-performing
assets, net interest margin, efficiency ratio, return on average assets, return
on average equity, price/earnings, price/book and dividend yield. For purposes
of this analysis, non-performing assets include non-accrual loans, restructured
loans, other real estate owned and loans 90 days past due but still accruing.
The calculation of net interest margin in this analysis does not include an
adjustment for tax-equivalent yield on tax-free securities. The analysis showed
that:

          -    Citizens' loans/deposits ratio was 52.9% versus the peer group
               median of 75.3%;

          -    Citizens' equity/assets ratio was 13.35% versus the peer group
               median of 9.07%;

          -    Citizens' ratio of non-performing assets to total assets was
               0.23% versus the peer group median of 0.65%;

          -    Citizens' allowance for loan losses/non-performing assets ratio
               was 195.3% versus the peer group median of 94.8%;

          -    Citizens' net interest margin was 3.50% versus the peer group
               median of 3.77%;

          -    Citizens' efficiency ratio was 68.22% versus the peer group
               median of 58.44%; and

          -    Citizens' return on average assets and return on average equity
               were 1.08% and 7.68% versus the peer group medians of 1.16% and
               11.24%, respectively.

         Summary Comparison of Selected Institutions - Harleysville. Tucker
Anthony compared selected balance sheet data, asset quality, capitalization and
profitability ratios and market statistics using financial data at or for the
twelve months ended September 30, 1999 and market data as of December 14, 1999
for Harleysville and market data as of December 14, 1999 for a group of New
Jersey, New York, Pennsylvania, Ohio and Virginia banks and bank holding
companies consisting of 13 institutions with total assets between $807.1 million
and $2.2 billion (the "Harleysville Peer Group"). The analysis included, but was
not limited to, the following ratios: loans/deposits, equity/assets,
non-performing assets/total assets, allowance for loan losses/ non-performing
assets, net interest margin, efficiency ratio, return on average assets, return
on

                                       27

average equity, price/earnings, price/book and dividend yield. For purposes of
this analysis, non-performing assets include non-accrual loans, restructured
loans, other real estate owned and loans 90 days past due but still accruing.
The analysis showed that:

          -    Harleysville's loans/deposits ratio was 86.1% versus the peer
               group median of 88.4%;

          -    Harleysville's equity/assets ratio was 8.02% versus the peer
               group median of 7.20%;

          -    Harleysville's ratio of non-performing assets to total assets was
               0.48% versus the peer group median of 0.52%;

          -    Harleysville's allowance for loan losses/non-performing assets
               ratio was 184.7% versus the peer group median of 161.7%;

          -    Harleysville's net interest margin was 4.59% versus the peer
               group median of 4.34%;

          -    Harleysville's efficiency ratio was 55.27% versus the peer group
               median of 56.68%;

          -    Harleysville's return on average assets and return on average
               equity were 1.53% and 17.24% versus the peer group medians of
               0.94% and 11.61%;

          -    Harleysville's price/earnings and price/book ratios were 11.6x
               and 197.9% versus the peer group medians of 13.5x and 181.3%;

          -    Harleysville's dividend yield was 3.52% versus the peer group
               median of 3.12%.

         Summary of Selected Bank Merger and Acquisition Transactions. Tucker
Anthony compared the ratios of price/book, price/trailing 12 months earnings,
book/book, and price/deposits for the merger to the average and median ratios
for a group of 20 bank merger transactions announced since January 1, 1995. The
selected transactions involved the acquisition of profitable commercial banks
and bank holding companies headquartered in Maryland, New Jersey, New York,
Ohio, Pennsylvania and West Virginia in which the target company's equity/asset
ratio exceeded 10% and asset size was less than $250 million. This analysis
showed that:

          -    The merger consideration represented 168.7% of Citizens'
               fully-diluted book value versus a median and average of 199.2%
               and 204.6% for the selected transactions;


                                       28
<PAGE>   35
          -    The merger consideration represented a price/trailing 12 months
               earnings ratio of 21.3x compared to a median and average of 20.0x
               and 21.3x for the selected transactions;

          -    The merger consideration represented a book/book ratio of 86.8%
               compared to a median and average of 103.2% and 105.7% for
               selected transactions; and

          -    The merger consideration represented a price/deposits ratio of
               27.3% compared to a median and average of 28.8% and 32.3% for the
               selected transactions.

         No company or transaction used in the above analysis as a comparison is
identical to Citizens, Harleysville or the contemplated transaction.
Accordingly, an analysis of the results of the foregoing is not mathematical;
rather, it involves complex consideration and judgments concerning differences
in financial and operating characteristics of the companies and other factors
that could affect the public trading value of the companies to which they are
being compared. The ranges of valuations resulting from any particular analysis
described above should not be taken to be Tucker Anthony's view of the actual
value of Citizens or Harleysville. The fact that any specific analysis has been
referred to in the summary above is not meant to indicate that such analysis was
given more weight than any other analyses.

         In performing its analyses, Tucker Anthony made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of Citizens or
Harleysville. The analyses performed by Tucker Anthony are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by the analyses. The analyses do not
purport to be appraisals or to reflect the prices at which a company might
actually be sold or the prices at which any securities may trade at the present
time or at any time in the future. In addition, as described above, Tucker
Anthony's opinion and presentation to the Citizens Board is just one of many
factors taken into consideration by the Citizens Board.

         Citizens agreed to pay Tucker Anthony a fee of 1.00% of the aggregate
consideration to be paid in the merger and a retainer fee of $5,000. Citizens
paid Tucker Anthony $20,000 upon delivery of Tucker Anthony's written fairness
opinion on December 28, 1999. The balance of the fee is due upon consummation of
the merger. Both the retainer fee and the $20,000 payment will be credited
towards the fee due upon closing. Tucker Anthony will be reimbursed for
reasonable out-of-pocket expenses incurred on behalf of Citizens. Citizens has
agreed to indemnify Tucker Anthony against certain liabilities.

                          INFORMATION ABOUT THE MERGER

DISSENTERS' RIGHTS

         Section 215a of Title 12, United States Code (12 U.S.C. Section 215a)
provides that any Citizens shareholder who wishes to exercise dissenters' rights
with respect to the proposed merger must either:

         -    vote against the proposed merger; or

         -     file a written notice prior to or at the special meeting convened
               to vote on the merger, stating that he or she dissents from the
               merger. The written notice should be addressed to:

               James A. Wimmer, Chairman and President
               Citizens Bank and Trust Company
               372 Delaware Avenue
               Post Office Box 196
               Palmerton, Pennsylvania 18071-0196

In addition, a shareholder who wishes to exercise dissenters' rights must make a
written request for payment to Harleysville, accompanied by the surrender of his
or her Citizens capital stock certificates before 30 days after the effective
date of the merger. The written request and surrender should be sent to:

               Jo Ann M. Bynon, Secretary
               Harleysville National Corporation
               483 Main Street
               Harleysville, Pennsylvania 19438.

Dissenting shareholders who fail to follow the procedure specified in this
paragraph will lose their dissenters' rights.

         After the effective date of the merger, any dissenting shareholder who
complies with the procedures described in the preceding paragraph will be
entitled to receive the value of the surrendered shares of Citizens capital
stock, determined as of the effective date of the merger. An appraisal committee
of three people will determine the value of the capital stock. Qualifying
dissenting shareholders will choose one member of the appraisal committee by
majority vote. The Citizens Board of Directors will name one member of the
committee. The two members of the committee will select the third member. Any
two members of the appraisal committee may agree on the valuation of the shares.

         If the appraisal committee's evaluation is not satisfactory to any
qualifying dissenting shareholder, the shareholder may appeal to the Office of
the Comptroller of the Currency, within 5 days after receipt of notice of the
evaluation. The Comptroller of the Currency will make a binding and final
reappraisal as to the value of the shares held by the shareholder. If within 90
days from the effective date of the merger:

                                       30
<PAGE>   37
          -    one or more appraisal committee members have not been selected
               for any reason; or

          -    the appraisal committee is not able to agree by a vote of two or
               more members, on the value of the shares held by qualifying
               dissenting shareholders,

the Comptroller of the Currency, on the request of any interested party, will
make a binding and final appraisal of the value of the shares. Harleysville will
pay the expenses of the Comptroller of the Currency for its reappraisal or
appraisal.

         This discussion is only a summary of the rights and obligations of a
dissenting shareholder. We qualify the discussion by reference to the provisions
of Section 215a of Title 12 of the United States Code, which we attach as Annex
C to this prospectus/proxy statement. Please read it carefully. If you fail to
follow the procedures in the statute you will lose your right to dissent. You
may wish to consult legal counsel if you are considering a possible exercise of
dissenters' rights.

TERMS OF THE MERGER

         We discuss the material terms of merger below. Our description is not
complete. We qualify the discussion in its entirety by reference to the
agreement, a copy of which we attach as Annex A and incorporate by reference in
this proxy statement/prospectus. We urge you to read the agreement.

Effect of the Merger

         Citizens Bank and Trust Company will merge into Citizens National Bank.
Citizens Bank and Trust Company will cease to exist. Citizens National Bank will
be the surviving institution.

Exchange of Shares

         On the day of the merger, each outstanding share of Citizens Bank and
Trust Company capital stock will become the right to receive 166 shares of
Harleysville common stock, subject to adjustment for stock dividends, stock
splits and similar transactions.

         Citizens shareholders should recognize that the market price of the
Harleysville common stock may fluctuate between the date of this proxy
statement/prospectus and the effective date of the merger. Because the number of
shares of Harleysville common stock to be received by Citizens shareholders in
the merger is fixed, the value of those shares on the effective date of the
merger may be more than or less than the value of those shares on the date of
this proxy statement/prospectus. In effect, by agreeing to a fixed exchange
ratio, the Citizens Board of Directors agreed to accept, as of December 28,
1999, the date of the merger agreement, the economic risks of being a
Harleysville shareholder.

                                       31
<PAGE>   38
         Harleysville and Citizens anticipate that the merger will occur during
the second quarter of 2000, assuming no difficulties are encountered in
obtaining the required regulatory approvals and shareholder approval, and all
other conditions to closing are satisfied without unexpected delay. If for any
reason, however, the merger does not occur by September 30, 2000, and the
parties have not agreed otherwise prior to that date, either party may terminate
the agreement. See, "Business Pending the Merger--Conditions, Amendment and
Termination"for a discussion of the various termination provisions.

         Following the merger, former shareholders of Citizens will be required
to surrender their Citizens capital stock certificates to Harleysville's
transfer agent, American Stock Transfer and Trust Company, who will act as
exchange agent for the transaction. Each shareholder will receive detailed
instructions concerning the procedure for surrendering the certificates. Upon
proper surrender of stock certificates, each former shareholder of Citizens will
receive a stock certificate representing the number of shares of Harleysville
common stock into which the shares of Citizens were converted. Shareholders of
Citizens should not surrender their Citizens stock certificates for exchange
until they receive written instructions to do so.

         Following the merger and until properly requested and surrendered, each
Citizens stock certificate will be deemed for all corporate purposes to
represent the number of whole shares of Harleysville common stock that the
holder would be entitled to receive upon its surrender. However, Harleysville,
at its option, may withhold dividends payable after the merger to any former
shareholder of Citizens who has received written instructions from Harleysville
but has not surrendered their Citizens stock certificates. Any dividends
withheld will be paid without interest to any former shareholder of Citizens
upon the proper surrender of their Citizens stock certificates.

         Citizens shareholders must surrender all Citizens stock certificates to
American Stock Transfer within two years after the merger. In the event that any
former shareholder does not properly surrender his or her certificates within
that time, Harleysville may sell the shares of Harleysville common stock that
would otherwise have been issued and hold the net proceeds of the sale, together
with any previously accrued and unpaid dividends, in a non-interest bearing
account for the shareholder's benefit. After the sale, the former shareholder's
sole right is to collect the net proceeds and accumulated dividends. Subject to
laws of escheat, the net proceeds, cash and accumulated dividends will be paid
to the former shareholder of Citizens, without interest, upon proper surrender
of their Citizens stock certificates.

BUSINESS PENDING THE MERGER

         Citizens has agreed to conduct its business in the usual, regular and
ordinary course, consistent with prudent business judgment, pending the merger.
Among other things, Citizens will:

                 Not amend its Articles of Incorporation or Bylaws;

                                       32
<PAGE>   39
                          Not declare, set aside or pay any dividend or make
                          any other distribution in respect of its stock,
                          except that, as provided in Section 4.9 of the
                          agreement, Citizens may pay regular cash dividends in
                          amount not in excess of $40.00 per share in a manner
                          consistent with Citizens' prior practices, provided
                          that, if the date of the merger would entitle
                          Citizens shareholders to a quarterly cash dividend
                          for the respective quarter from Citizens and
                          subsequently from Harleysville, then Citizens shall
                          not pay a dividend in that quarter;

                          Not authorize, purchase, issue or sell any shares of
                          capital stock or any other equity or debt securities
                          convertible into Citizens' capital stock;

                          Not change the presently outstanding number of shares
                          or effect any capitalization, reclassification, stock
                          dividend, stock split or like change in
                          capitalization;

                          Not enter into or substantially modify (except as may
                          be required by applicable law) any pension,
                          retirement, stock option, stock warrant, stock
                          purchase, stock appreciation right, savings, profit
                          sharing, deferred compensation, severance,
                          consulting, bonus, group insurance or other employee

                          other employees except that Citizens may pay
                          retention bonuses, in an aggregate amount not to
                          exceed $40,000, to current employees, which retention
                          bonuses will be paid prior to the date of the merger;

                          Not make any loan or other credit facility commitment
                          in excess of $150,000 (including without limitation,

                          affiliate or compromise, expand, renew or modify any
                          such outstanding commitment;

                          Not enter into any swap or similar commitment,
                          agreement or arrangement that is not consistent with
                          past practice and that increases the credit or
                          interest rate risk over the levels existing at
                          December 31, 1998;

                          pursuant to policies agreed upon from time to time by
                          the parties.

MATERIAL CONTRACTS

         There have been no material contracts or other transactions between
Citizens and Harleysville since signing the agreement, nor have there been any
material contracts, arrangements, relationships or transactions between Citizens
and Harleysville during the past five years, other than in connection with the
agreement and as described in this proxy statement/prospectus.

CONDITIONS, AMENDMENT AND TERMINATION

         The obligations of Harleysville and Citizens to complete the merger are
subject to a number of conditions and contingencies. These are stated in the
agreement. The most significant of these conditions include:

                          Approval by the shareholders of Citizens;

                          Approval by, notice to or consent of the Board of
                          Governors of the Federal Reserve System, the Office
                          of the Comptroller of the Currency and the
                          Pennsylvania Department of Banking;

                          Receipt of an opinion of Grant Thornton, LLP
                          concerning certain federal income tax consequences
                          relating to the merger;

                          Continued effectiveness of the registration statement
                          containing the proxy statement/prospectus;

                          Determination that the merger can be accounted for as
                          a pooling of interests for financial reporting
                          purposes;

                          Determination of compliance with all applicable
                          federal and state securities and antitrust laws; and

                          Exercise by dissenting shareholders of dissenters'
                          rights with respect to no more than 5% of the bank's
                          capital stock.

         In connection with the regulatory approvals, Harleysville will file:

                                       34
<PAGE>   41
          -    A Notice with respect to the transaction with the Board of
               Governors of the Federal Reserve System, pursuant to Section
               3(a)(3) of the Bank Holding Company Act;

          -    An Application for Merger with the Office of the Comptroller of

               pursuant to Section 115 of the Pennsylvania Banking Code,
               including a Notice relating to the merger.

         Any term or condition of the agreement may be waived by the party that
would benefit from the term at any time before the merger, whether before or
after the approval of the agreement by Citizens' shareholders. However, the
parties may not adopt a change in the amount of consideration to be received by
Citizens shareholders unless the shareholders of Citizens approve the change. In
addition, if the parties waive the requirement that a tax opinion be delivered
at closing and the tax consequences to the Citizens shareholders are material,
Citizens would send revised materials to shareholders and solicit their
approval.

         The agreement may be terminated at any time before the merger, whether
before or after its approval and adoption by the shareholders of Citizens by:

               Agreement of all of the parties;

               Unilateral action by each of the parties in the event of a
               material breach by the other party of any representation,
               warranty or covenant not cured or curable within 30 days after
               written notice or any condition precedent to the terminating
               party's obligation to consummate the merger is not satisfied
               through no fault of the terminating party;

               By either party in the event of a failure to consummate the
               merger by September 30, 2000; or

          -    By Harleysville, if under circumstances described in Section
               7.1(e) of the agreement, Citizens is involved in a merger or
               other transaction with any other party or another party makes an
               offer or a proposal to acquire 20% of Citizens capital stock.

EFFECTIVE DATE

         The agreement provides that the merger will occur within 20 days after
receipt of all required approvals and the expiration of any required regulatory
waiting periods.

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

         The Board of Directors of Harleysville, following the merger, will
include the same persons who are members of the Board of Directors immediately
before the merger, each of whom will serve until his or her successor is elected
or appointed and qualified. In addition, Harleysville's Board of Directors will
appoint James A. Wimmer, Chairman, President and a Director of Citizens, to the
Harleysville Board of Directors to serve until his successor is elected or
appointed and qualified. Harleysville also will appoint Mr. Wimmer and Linda P.
Wimmer, who are husband and wife, to the Citizens National Bank Board of
Directors and will nominate and recommend them for election at each successive
election, as long as Mr. Wimmer remains a member of the Harleysville Board. This
may give them an interest in the transaction in addition to their interest as
shareholders. The Board of Directors was aware of these factors and considered
them, among other matters, in approving the agreement and the transactions
contemplated by the agreement.

         As of December 28, 1999, the directors and executive officers of
Citizens beneficially owned 3,114 shares of Citizens capital stock and the
directors and executive officers of Harleysville beneficially owned 710 shares
of Citizens capital stock.

          Mr. Wimmer, as a Director of Harleysville, will receive the same fees
and benefits as other members of the Harleysville Board. The directors of
Harleysville receive a fee of $425 for each board meeting attended, an annual
retainer of $7,000, and a fee of $310 for each committee meeting attended. All
together, as of September 30, 1999, the Board of Directors of Harleysville
received $146,377.50. In 1999, Mr. Wimmer received total compensation from
Citizens of $61,965, which included $10,440 as an annual fee to directors
$35,248 paid in salary and bonus as President and $16,277 for legal services
rendered as solicitor to Citizens.

         Harleysville also maintains a Deferred Compensation Plan for its
directors. In the past, certain directors elected to defer, with interest, all
or part of their compensation for future distribution. Under the terms of the
plan, benefits can be paid out to the respective directors over a ten-year
period. Should the director die before age 70 or before receiving all of the
benefits, those benefits would be paid to his or her beneficiary until age 70 or
for 10 years, whichever is later. The plan is considered an unfunded plan that
is subject to substantial risk of forfeiture and the director is not considered
vested pursuant to the plan.

         The directors and officers of Harleysville and its subsidiaries have no
special interest in the merger, other than in their capacity as shareholders of
Harleysville, and will not receive any special consideration or compensation in
connection with its consummation.

FEDERAL INCOME TAX CONSEQUENCES

         The following discussion summarizes the anticipated material federal
income tax consequences of the merger, if the merger were to take place on the
date of this proxy statement/prospectus. This is only a general description. We
attach the opinion of Grant Thornton LLP, independent, certified public
accountants for Harleysville, as to the income tax

                                       36
<PAGE>   43
consequences of the merger as Annex B. We recommend you read the opinion.
However, the opinion does not consider the particular facts and circumstances of
your situation. We recommend that you consult your own tax advisors as to
particular facts and circumstances that may be unique to you and not common to
shareholders as a whole, and also as to any estate, gift, state, local or
foreign tax consequences arising out of the transactions and/or any sale of
Harleysville common stock received in the merger. We do not anticipate that the
law will change before completion of the merger.

          The following is a summary of the opinion of Grant Thornton LLP:

          -    the merger will constitute a tax-free reorganization for U.S.
               federal income tax purposes;

          -    neither Citizens National Bank and Trust Company, Citizens
               National Bank nor Harleysville will recognize any gain or loss by
               reason of the merger;

          -    except for cash received in lieu of fractional shares, Citizens
               shareholders will not recognize gain or loss on the exchange of
               their shares of Citizens capital stock for shares of Harleysville
               common stock;

          -    the basis and holding period of the Harleysville common stock
               received by the Citizens shareholders generally will be, in each
               instance, the same as the basis and holding period of the
               Citizens National Bank and Trust Company capital stock
               surrendered in exchange provided that the Citizens capital stock
               surrendered is held as a capital asset on the date of the
               exchange; and

          -    payment of cash to the Citizens shareholders instead of their
               fractional share interests of Harleysville common stock generally
               will qualify as capital gain or loss because the cash will be
               treated as a distribution in full payment in exchange for the
               fractional share interest of Harleysville common stock that the
               shareholder would otherwise be entitled to receive.

           The obligations of the parties to close the transaction are
conditioned upon receipt of a ruling from the Internal Revenue Service or an
opinion of Grant Thornton substantially to the effect that the federal income
tax consequences of the merger are as summarized in this section. Unlike a
ruling from the IRS, Grant Thornton's opinion would have no binding effect on
the IRS. The ruling or opinion will not deal with all the tax considerations
that may be relevant to particular Citizens shareholders, such as shareholders
who are dealers in securities, foreign persons, tax exempt entities or the
impact of the alternative minimum tax. The ruling or opinion will not address
any state, local or foreign tax considerations.

ACCOUNTING TREATMENT

           The agreement contemplates that the merger will be treated as a
pooling of interests for financial accounting and reporting purposes. Under this
accounting method, the assets and

                                       37
<PAGE>   44
liabilities of Citizens Bank and Trust Company will be combined with Citizens
National Bank at their historical recorded bases. Results of operations of
Harleysville will include the results of both companies for the entire fiscal
year in which the merger occurs. The reported balance sheet amounts and results
of operations of the separate banks for the prior periods will be combined,
reclassified and conformed, as appropriate, to reflect the combined financial
position and results of operations for Harleysville.

         If Harleysville would be required to purchase more than 10% of the
outstanding shares of Citizens capital stock for cash due to the exercise of
dissenters' rights by Citizens shareholders, or if other conditions arise that
would prevent the merger from being treated as a pooling of interests for
financial accounting purposes, Harleysville has the right to terminate the
agreement and to cancel the merger.

RESTRICTION ON RESALE OF STOCK HELD BY AFFILIATES

         The shares of Harleysville common stock to be issued upon completion of
the merger have been registered with the Commission under the Securities Act.
Following the merger, these shares may be freely resold or otherwise transferred
by all former shareholders of Citizens, except those former shareholders who are
deemed "affiliates" of Citizens, within the meaning of Commission Rules 144 and
145. In general terms, any person who is an executive officer, director or 10%
shareholder of Citizens at the time of the meeting may be deemed to be an
affiliate of Citizens for purposes of Commission Rules 144 and 145. This proxy
statement/prospectus does not cover resales of shares of Harleysville common
stock to be issued to affiliates of Citizens in connection with the transaction.

         Harleysville common stock received by persons who are deemed to be
affiliates of Citizens may be resold only:

               In compliance with the provisions of Commission Rule 145(d);

               In compliance with the provisions of another applicable exemption
               from the registration requirements of the Securities Act; or

               Pursuant to an effective registration statement filed with the
               Commission.

In general terms, Commission Rule 145(d) permits an affiliate of Citizens to
sell shares of Harleysville common stock he or she received in ordinary
brokerage transactions subject to certain limitations on the number of shares
that may be sold in any consecutive three month period.

         The ability of affiliates to resell shares of Harleysville common stock
received in the transaction under Rule 144 or Rule 145, is subject to
Harleysville's having satisfied its Exchange Act reporting requirements for
specified periods prior to the time of sale. Affiliates are also permitted to
resell Harleysville common stock received in the transaction pursuant to an
effective

                                       38
<PAGE>   45
registration statement under the Securities Act or another available exemption
from the Securities Act regulations and requirements. This proxy
statement/prospectus does not cover any resales of Harleysville common stock
received by persons who may be deemed to be affiliates of Harleysville or
Citizens.

         Each person who may be an affiliate of Citizens is required, prior to
the closing, to provide Harleysville with a letter agreeing to abide by the
limitations imposed by the Commission regarding the sale or other disposition of
the shares of Harleysville common stock that the shareholders will receive in
the merger.

         In addition, a requirement of pooling-of-interests accounting treatment
of the merger is that an affiliate of Citizens may not, as a general rule and
subject to an exception in a case of certain de minimis sales:

               Sell any shares of Citizens capital stock during the 30-day
               period immediately preceding the day of the merger; or

               Sell any shares of Harleysville common stock received by him or
               her in exchange for his or her shares of Citizens capital stock
               until after the publication of financial results covering at
               least 30 days of post-merger combined operations.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of management and of the Board of Directors of Citizens
may be deemed to have interests in the merger in addition to their interests, if
any, in Citizens capital stock. The Citizens Board of Directors was aware of
these factors and considered them, among other matters, in approving the merger
agreement.

SHARES OWNED BY MANAGEMENT AND THE BOARD

         As of the record date, the directors and officers of Citizens
beneficially own approximately 3,114 shares (56.2%) of Citizens capital stock.

DIRECTORS AND OFFICERS INSURANCE

         Harleysville has agreed, in the merger agreement, to maintain a
Director and Officer Liability Insurance Tail Policy for the directors and
officers of Citizens for a period of six (6) years after the date the merger is
completed. Such policy shall include conditions and terms the same as or
substantially comparable to the Directors and Officer Liability Policy of
Citizens on the date of the merger agreement.

         In the merger agreement, Harleysville has agreed that, immediately
after completion of the merger, James A. Wimmer, President, Chairman and a

Linda P. Wimmer, his wife and a Director of Citizens, shall be appointed to the
Board of Directors of Citizens National Bank. In their capacities as Directors,
Mr. Wimmer and Mrs. Wimmer will receive the same fees and benefits as other
members of the Harleysville and/or Citizens National Bank Boards of Directors.

BENEFITS

         Citizens National Bank has agreed to pay health insurance premiums for
Citizens Bank and Trust Company retirees and directors for three years from the
day of the merger, up to an aggregate of $46,408 per year.

HARLEYSVILLE DIRECTORS AND OFFICERS

         The directors and officers of Harleysville and its subsidiaries have no
special interest in the merger, other than in their capacity as shareholders of
Harleysville. The directors and officers of Harleysville and its subsidiaries
will not receive any special consideration or compensation in connection with
the completion of the merger.

negotiated transactions. Citizens does not have the ability to monitor the sales
price of its capital stock in transactions to which it is not a party. The last
transaction in which Citizens was a party was the purchase by Citizens of 14
shares at a price of $4,250 per share on January 27, 1999. Citizens has in the
past paid regular quarterly dividends to its shareholders on or about March 1,
June 1, September 1 and December 1, of each year.

         The sales reported below reflect purchases by Citizens of its own
capital stock pursuant to a repurchase program adopted by the Board of
Directors. The tables below do not reflect any transactions of which Directors
or Officers of Citizens may have individual personal knowledge of virtue of
their status as private parties to the transactions in their individual
capacities.

ACQUISITIONS BY HARLEYSVILLE NATIONAL CORPORATION

         Harleysville was incorporated in June 1982. On January 1, 1983,

Corporation acquired all of the outstanding common stock of The Citizens
National Bank of Lansford. On June 1, 1992, the Corporation acquired all of the

                                       45
<PAGE>   52
Merchants Bank was merged into The Citizens National Bank of Lansford and is now
operating as a branch office of The Citizens National Bank of Lansford.

         On January 20, 1999, Harleysville acquired Northern Lehigh Bancorp,
Inc., parent company of Citizens National Bank of Slatington. The transaction
was accounted for as a pooling-of-interests. Northern Lehigh shareholders
received 3.57 shares of Harleysville common stock for each share of Northern
Lehigh common stock. The acquisition was effected by the merger of Northern
Lehigh Bancorp, Inc. with Harleysville National Corporation North, Inc., a bank
holding company and wholly owned subsidiary of Harleysville National
Corporation. Citizens National Bank of Slatington merged with and into The
Citizens National Bank of Lansford, a national banking association and wholly
owned subsidiary of Harleysville National Corporation North, Inc., under the
name "Citizens National Bank." Harleysville is in the process of liquidating
Harleysville North. After completion of the proposed merger Citizens National
Bank will be a direct subsidiary of Harleysville.

         On March 17, 1997, Harleysville National Corporation Financial Company
was incorporated as a Delaware corporation. Harleysville National Corporation
Financial Company's principal business function is to expand the investment
opportunities of Harleysville National Corporation.

         Harleysville National Corporation is primarily a bank holding company
which provides financial services through its three bank subsidiaries. Since
commencing operations, Harleysville National Corporation's business has
consisted primarily of managing its subsidiary banks, and its principal source
of income has been dividends paid by the banks. Harleysville National
Corporation is registered as a bank holding company under the Bank Holding
Company Act of 1956.

LOANS

         Harleysville, through its subsidiaries, grants loans and makes other
credit available to the general public. These extensions of credit are
structured to meet the varying needs of businesses, individuals, and
institutional customers and include mortgages, lines of credit, term loans,
leases and letters of credit. This activity comprises a major source of revenue
for Harleysville's subsidiaries and it also exposes Harleysville and its
subsidiaries to potential losses upon borrower default. In order to minimize the
occurrence of loss, Harleysville's subsidiaries follow strict loan underwriting
and risk weighing policies. While collateral continues to play an important part
in lending decisions, primary emphasis is placed upon borrowers' underlying
ability to pay. Harleysville's subsidiaries confine their lending activity to
customers who live or are based in their respective market areas. By limiting
lending activities to a specific geographic area, the staff of each subsidiary
becomes more knowledgeable about local market conditions and can thereby make
better credit risk assessments and consequently more prudent lending decisions.
Harleysville believes that this local knowledge, when combined with prudent
underwriting standards, overcomes the risks associated with the geographic
concentration of loans.

             DESCRIPTION OF HARLEYSVILLE NATIONAL CORPORATION COMMON
                                      STOCK

         Harleysville National Corporation is authorized to issue 30,000,000
shares of Harleysville National Corporation common stock of which 7,915,130
shares were issued and outstanding as of December 31, 1999. Harleysville also
has 3,000,000 shares of blank check preferred stock authorized for issuance. No
preferred stock is outstanding as of January 30, 2000.

DIVIDENDS

         The holders of Harleysville common stock are entitled to receive
dividends when, as and if declared by the Board of Directors out of legally
available funds. Harleysville has historically paid quarterly cash dividends to
its shareholders on or about March 31, June 30, September 30, and December 31,
of each year.

         The ability of Harleysville to pay dividends to its shareholders is
dependent primarily upon the earnings and financial condition of The
Harleysville National Bank and Trust Company, Citizens National Bank and
Security National Bank. Harleysville expects to obtain funds for the payment of
dividends on Harleysville stock, for the foreseeable future, primarily from
dividends paid by its subsidiaries. These dividends are subject to certain
statutory limitations.

         Under applicable federal laws, the dividends that Harleysville's
banking subsidiaries may pay without prior regulatory approval are subject to
certain prescribed limitations. Because Harleysville's banking subsidiaries are
national banks, the approval of the Office of the Comptroller of the Currency is
required under federal law if the total of all dividends declared during any
calendar year exceed the total of the net profits of the respective bank for the
year, combined with its retained net profits, for the two preceding years. In
addition to the foregoing statutory restrictions on dividends, the Office of the
Comptroller of the Currency also has general authority to prohibit a national
bank from engaging in an unsafe or unsound banking practice. The Office of the
Comptroller of the Currency could consider a bank's payment of a dividend,
depending upon the financial condition of the bank involved and other factors,
to be an unsafe or unsound practice.

         Harleysville paid cash dividends of $.95 per share in 1998, and paid
cash dividends of $1.07 per share in 1999.

LIQUIDATION

         In the event of liquidation, dissolution or winding up of Harleysville,
Harleysville's shareholders are entitled to share ratably in all assets
remaining after payment of liabilities,


                                       47
<PAGE>   54
subject to prior distribution rights of Harleysville preferred stock, if any,
then outstanding. On January 30, 2000, no shares of Harleysville preferred stock
were issued or outstanding.

DIVIDEND REINVESTMENT PLAN

         Harleysville has a Dividend Reinvestment and Stock Purchase Plan.
Shareholders of Harleysville may elect to participate in the plan. The plan is
administered by American Stock Transfer and Trust Company, as plan agent. Under
the plan, dividends payable to participating shareholders are paid to the plan
agent and are used to purchase, on behalf of the participating shareholders,
additional shares of Harleysville common stock either in the market or from
Harleysville's authorized but unissued shares. Participating shareholders may
make additional voluntary cash payments that are also used by the plan agent to
purchase additional shares of stock. Shares of Harleysville common stock held
for the account of participating shareholders and are voted by the plan agent as
instructed by each participating shareholder.

ANTITAKEOVER PROVISIONS

         The Pennsylvania Business Corporation Law of 1988 and Harleysville's
amended Articles of Incorporation and amended Bylaws provide numerous provisions
that may be deemed to be antitakeover in nature, both as to purpose and effect.
There are four major antitakeover provisions under Pennsylvania law relating to
corporations that have their securities registered with the Commission under
Section 12 of the Securities Act.

         The overall effect of the various provisions described below might be
to deter a tender offer or other proposal that a majority of the shareholders
may view to be in their best interest. Such an offer might include a substantial
premium over the market price of Harleysville's common stock. In addition, these
provisions may have the effect of assisting Harleysville's current management in
retaining its position and placing it in a better position to resist changes
that shareholders may want to make if dissatisfied with the conduct of
Harleysville's business.

         Two of these provisions have the effect of eliminating the rights of
the shareholders of registered corporations to:

                 Call a special meeting of shareholders; and

                 Propose an amendment to the Articles of Incorporation.

These provisions may prevent shareholders from calling a special meeting for the
purpose of considering a merger, consolidation or other corporate combination
that does not have the approval of a majority of the members of Harleysville's
Board of Directors. These provisions may have the effect of making Harleysville
less attractive as a potential takeover candidate by depriving shareholders of
the opportunity to initiate special meetings at which a possible business
combination might be proposed. Antitakeover provisions may provide a greater
time


                                       48
<PAGE>   55
for consideration of any shareholder proposal to the extent that the proposal
must be deferred until the next annual meeting of shareholders.

         Also, when made, shareholder proposals must comply with certain notice
requirements and proxy solicitation rules. These requirements do not affect the
calling of a special meeting by the Chairman of the Board or by a majority of
the members of the Board of Directors or of its Executive Committee if, in their
judgment, there are matters to be acted upon that are in the best interests of
Harleysville and its shareholders.

         Harleysville's Articles of Incorporation and amended Bylaws contain a
number of additional provisions that may be antitakeover in purpose and effect.
These provisions include:

                  Authorization of 30,000,000 shares of common stock and
                  3,000,000 shares of preferred stock;

                  Lack of preemptive rights for shareholders to subscribe to
                  purchase additional shares of stock on a pro rata basis;

                  The necessity for the affirmative vote of the holders of 80%
                  of Harleysville's common stock to approve an amendment to
                  Harleysville's Bylaws or to change an amendment to its Bylaws
                  that was approved by the Board of Directors; and

                  The necessity for the affirmative vote of the holders of 80%
                  of Harleysville's common stock to approve a merger,
                  consolidation, liquidation, or sale of substantially all
                  assets unless the transaction has received prior approval of
                  at least 75% of all members of the Board of Directors, in
                  which case, a majority of the outstanding shares of common
                  stock is required for approval.

These provisions could give the holders of a minority of Harleysville's
outstanding shares a veto power over any merger, consolidation, dissolution or
liquidation of Harleysville, the sale of all or substantially all of its assets
or an amendment to its Bylaws unless 75% of all members of the Board of
Directors and a majority of the shareholders believe that the transaction is
desirable and beneficial. Without these provisions in Harleysville's Articles of
Incorporation and Bylaws, the affirmative vote of at least a majority of
Harleysville's common stock outstanding and entitled to vote would be required
to approve any merger, consolidation, dissolution, liquidation, the sale of all
of its assets or an amendment to the Bylaws.

         Provisions for a classified or staggered board are included in
Harleysville's amended Bylaws. A classified board has the effect of moderating
the pace of any change in control of the Board of Directors by extending the
time required to elect a majority of the directors to at least two successive
annual meetings. However, this extension of time may also tend to discourage a
tender offer or takeover bid. In addition, a classified board makes it more
difficult for a majority


                                       49
<PAGE>   56
of the shareholders to promptly change the composition of the board of directors
even though they consider a prompt change desirable.

         Harleysville's amended Articles of Incorporation contain an additional
antitakeover provision that enables the Board of Directors to oppose a tender
offer on the basis of factors other than the short term economic benefit to
shareholders. Based on the Board's responsibilities to certain constituent
groups, including Harleysville's subsidiaries and the communities they serve,
the Board may consider factors such as:

         -        The impact the acquisition of Harleysville would have on the
                  community;

         -        The effect of the acquisition upon shareholders, employees,
                  depositors, suppliers and customers; and

         -        The reputation and business practices of the tender offeror.

                                 INDEMNIFICATION

         Harleysville's Bylaws provide for indemnification of its directors,
officers, employees and agents to the fullest extent permitted under the laws of
the Commonwealth of Pennsylvania, provided that the person seeking
indemnification acted in good faith, in a manner he or she reasonably believed
to be in the best interest of the corporation, and without willful misconduct or
recklessness.

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

                        COMPARISON OF SHAREHOLDER RIGHTS

         After the merger, the shareholders of Citizens will become shareholders
of Harleysville. There are certain differences in the rights of shareholders of
these two companies and the differences in the laws that govern the two
companies. The most significant of these differences are those relating to
antitakeover protection and public registration. The Harleysville common stock
is registered under the Securities Exchange Act of 1934 and is traded on the
NASDAQ National Market System, while Citizens capital stock is not registered
under the Securities Exchange Act of 1934, and is traded on a limited basis in
privately negotiated transactions.

         The Bylaws of Harleysville provide for a classified Board of Directors
under which there are four classes of directors and, accordingly, one-fourth of
the directors are elected each year for a term of four years. The Citizens Board
of Directors is not classified. All the directors are elected each year. The
classification of the Board of Directors of a company makes it more difficult
for the shareholders of the company to change a majority of the directors, even
when a majority of the shareholders may desire such a change. It would normally
take three annual meetings of Harleysville National Corporation's shareholders
in order to replace a majority of Harleysville National Corporation's directors,
whereas it would take one annual meeting of Citizens' shareholders to replace a
majority of Citizens' Board of Directors.

         In addition to classification of the Board of Directors, the Articles
of Incorporation and Bylaws of Harleysville include a number of provisions that
are intended to protect the shareholders but that may be considered to be
antitakeover in nature and may serve to entrench the current management of
Harleysville National Corporation. See "DESCRIPTION OF HARLEYSVILLE NATIONAL
CORPORATION COMMON STOCK--Antitakeover Provisions."

         Harleysville common stock, unlike Citizens capital stock, is registered
with the Commission under Section 12(g) of the Exchange Act. As a result,
Harleysville is subject to the periodic reporting, proxy solicitation and
insider trading requirements of the Exchange Act, which do not apply to
Citizens. Pursuant to these requirements, Harleysville makes available to
shareholders, potential investors and the general public a significant amount of
information regarding Harleysville in the form of proxy statements, periodic
reports and other Commission filings. In addition, directors, executive officers
and beneficial shareholders of more than 10% of the issued and outstanding
shares of Harleysville National Corporation common stock are subject to the
insider trading reporting requirements and short-swing profit recapture
provisions of Section 16 of the Exchange Act.

         We summarize material differences between Citizens capital stock and
Harleysville common stock and the rights of their respective holders, as of
January 30, 1999, are summarized in the following table:

         Citizens' trust department offers a full range of personal and
corporate trust services. It administers and provides investment management
services for estates, trusts, agency accounts and employee benefit plans.

COMPETITION

         Citizens competes with other commercial banks and savings and loan
associations, most of which are larger than Citizens. The bank also competes
with major regional banking and financial institutions headquartered elsewhere.
Citizens generates the overwhelming majority of its deposit and loan volume
within its primary service area which includes southern Carbon County, western
Monroe County and the northern tiers of Lehigh and Northampton Counties,
Pennsylvania.

         As of June 1998, Citizens ranked fourth in terms of total deposits in
Carbon County with 10.25%, tenth in Monroe County with 2.18% and twenty-fifth in
Northampton County with .13%. Citizens considers its major competition in its
primary area to include First National Bank of Palmerton, Keystone Savings
Association, Citizens National Bank, East Stroudsburg Savings Association and
Nazareth National Bank, as well as larger institutions such as First Union
National Bank, Mellon Bank and PNC Bank.

         The primary service area constitutes the community delineated for
Citizens' Community Reinvestment Act Statement which states the bank intends to
meet the credit needs of the entire local community. It is Citizens' policy to
evaluate all applications for credit without regard to the applicant's race,
color, creed, sex, age or marital status.

         The primary service area includes a wide variety of residential
neighborhoods, commercial businesses, retail stores, industrial complexes and
service institutions, as well as a large number of established businesses and a
substantial employment base.

EMPLOYEES

         As of December 31, 1999, Citizens had 43.25 full-time equivalent
employees.

LEGAL PROCEEDINGS

         The nature of Citizens' business generates a certain amount of
litigation involving matters in the ordinary course of business. In the opinion
of Citizens management, there are no proceedings pending to which Citizens is a
party or to which its property is subject, that, if determined adversely to
Citizens, would be material to Citizens' undivided profits or financial
condition, nor are there any proceedings pending, other than ordinary routine
litigation, incident to Citizens' business. In addition, no material proceedings
are pending or are known to be threatened or contemplated against Citizens by
government authorities or others.

DIVIDENDS

         Citizens' shareholders are entitled to receive the dividends when, as
and if declared by the Board of Directors out of legally available funds.
Citizens has historically paid quarterly cash dividends to its shareholders on
or about March 1, June 1, September 1 and December 1 of each year.

         Under the Pennsylvania Banking Code of 1965, as amended, Citizens'
Board of Directors may declare and pay dividends out of the Bank's accumulated
net earnings. As of September 30, 1999, Citizens had approximately $12,323,000
available for the payment of dividends. The agreement permits Citizens to make
normal dividend payments to its shareholders, consistent with past practice,
prior to the day of the merger. Citizens paid cash dividends of $140 per share
in 1998, and $160 per share in 1999.

PRINCIPAL OWNERS OF CITIZENS CAPITAL STOCK

         The following table shows, as of February 11, 2000, the name and
address of each person who owns of record or who is known by the Citizens Board
of Directors to own more than 5% of Citizens outstanding capital stock, the
number of shares beneficially owned by the person and the percentage of the
Citizens outstanding capital stock so owned.

         We determined beneficial ownership by applying Commission Rule 13d-3,
which states that a person should be credited with the ownership of any stock
that he or she, directly or indirectly, through any contract, arrangement,
understanding, relationship or otherwise has or shares:

                  Voting power, which includes the power to vote or to direct
                  the voting of the stock, or

                  Investment power, which includes the power to dispose or
                  direct the disposition of the stock, or has the right to
                  acquire beneficial ownership within 60 days after February 11,
                  2000, the record date of the meeting.

Introduction


      Citizens net income for the first nine months of 1999 of $1,038,000 was
$54,000 or 4.9% lower than earnings for the same period in 1998 of $1,092,000.
This decrease in net income was due to higher operating expenses partially
offset by lower federal income taxes related to an increase in tax-free income
during 1999. Total assets at September 30, 1999 increased $973,000 or .7%,
compared to September 30, 1998. This increase was the result of a $745,000 rise
in loans and a $1,266,000 growth in cash and cash equivalents, partially offset
by a reduction in investment securities. The increase in assets was funded by a
$2,425,000 increase in deposits and a $1,079,000 rise in other borrowed funds,
and partially offset by a $1,554,000 decrease in securities sold under agreement
to repurchase and a reduction in shareholders' equity. At September 30, 1999,
Citizens asset quality remained high. There were no loans in non-accrual status
and delinquent loans were only .52% of total loans outstanding.

while the average balance of investment securities decreased $2,129,000, or

</TABLE>

Weighted average yield is commuted by dividing the annualized interest income,
including the accretion of discounts and the amortization of premiums, by the
carrying value. Tax-exempt securities were adjusted to a tax-equivalent basis
and are based on the federal statutory tax rate of 34%.

Investment Securities

      Total securities of $59,428,000 decreased $1,883,000 from September 30,
1998 to September 30, 1999. This decrease was the result of Citizens decreasing
both the available for sale portfolio and the held to maturity portfolios by
$1,377,000 and $506,000, respectively. During the period from September 30, 1998
to September 30, 1999, the bank used the proceeds from both the sale and
maturity of U.S. Treasury securities and mortgage-backed securities to fund the
purchase of higher yielding U.S. Government agency obligations and obligations
of states and political subdivision securities. The September 30, 1999 security
portfolio balance did not change significantly from the December 31, 1998
balance of $59,988,000 and the December 31, 1997 balance of $61,118,000.

      The September 30, 1999 federal funds sold balance of $4,375,000 was
slightly lower than the $4,425,000 balance at September 30, 1998. The September
30, 1999 balance was $675,000 lower than the December 31, 1998 balance of
$5,050,000 and $1,575,000 higher than the December 31, 1997 balance of
$2,800,000.

Loans

      Loans grew $770,000, or 1.3% from $57,313,000 at September 30, 1998 to
$58,083,000 at September 30, 1999. This growth was due to increases in the
commercial and installment portfolios of $588,000 and $403,000, respectively.
These increases were offset by a $221,000 decrease in mortgages. The September
30, 1999 balance was 1.3% higher than the December 31, 1998 balance as a result
of growth in the commercial and installment portfolios. The September 30, 1999
balance was 5.9% higher than the December 31, 1997 balance due to a rise in the
installment and mortgage portfolios.


Major classifications of loans are summarized as follows at September 30, 1999

interest has consistently been in default for a period of 90 days or more or
because of a deterioration in the financial condition of the borrower or payment

days or more and still accruing interest are generally well-secured and expected
to be restored to a current status in the near future. The following table
details those loans that were placed on non-accrual status, were accounted for
as troubled debt restructurings or were delinquent 90 days or more and still
accruing interest:

      The allowance for loan losses is maintained at a level considered adequate
to provide for losses that can be reasonably anticipated. Management's periodic
evaluation of the adequacy of the allowance is based on the Bank's past loan
loss experience, known and inherent risks in the portfolio, adverse situations
that may affect the borrower's ability to repay, the estimated value of any
underlying collateral, composition of the loan portfolio, current economic
conditions and other relevant factors. This evaluation is inherently subjective
as it requires material estimates that may be susceptible to significant change.

      The allowance for loan losses of $586,000 at September 30, 1999 was 1.01%
of loans, compared to 0.95% of loans at September 30, 1998. This increase is due
to Citizens Bank and Trust Company adding $39,000 to the allowance and
recovering $7,000 of loans previously charged off, during the first nine months
of 1999. Citizens Bank and Trust Company did not charge off any loans during the
first nine months of 1999. The $540,000 allowance for possible loan losses at
December 31, 1998 was 0.95% of loans and the $516,000 allowance for loan losses
at December 31, 1997 was also 0.95%.

     Total deposits of $109,300,000 at September 30, 1999 were $2,425,000, or
2.3% higher than the September 30, 1998 balance of $106,875,000. This increase
was primarily the result of a $2,273,000 rise in non-interest bearing deposits.
Also during the period, interest-bearing checking accounts grew $1,059,000 and
savings accounts increased $1,040,000. Partially offsetting these rises were
decreases to money market accounts, time deposits under $100,000 and time
deposits over $100,000 of $12,000, $491,000 and $1,444,000, respectively. The
September 30, 1999 balance grew $2,290,000 from the December 31, 1998 balance of
$107,010,000 and $4,576,000 from the December 31, 1997 deposit balance of
$104,724,000.

     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 possible 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 (set forth below) of
total and Tier 1 capital (as defined in the regulations) to risk-weighted
assets, and of Tier 1 capital to average assets. Management believes, as of
September 30, 1999, that the Bank meets all capital adequacy requirements to
which it is subject.

     As of September 30, 1999, the most recent notification from the Federal
Deposit Insurance Corporation categorized the Bank as well capitalized under the
regulatory framework for prompt corrective action. To be categorized as well
capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based
and Tier 1 leverage ratios as set forth in the table. There are no conditions or
events since that notification that management believes have changed the Bank's
category.

The Bank's actual capital amounts and ratios are presented in the following
table.

Results of Operations
- ---------------------

     Net income for the first nine months of 1999 of $1,038,000 was $54,000, or
4.9% below the first nine months of 1998. The basic and diluted earnings per
share for the first nine months of 1999 and 1998 were $187.20 and $193.07,
respectively. This decrease in net income was due to higher operating expenses
and partially offset by lower federal income taxes related to the increase in
tax-free income during 1999. The December 31, 1998 net income of $1,451,000 was
4.7% higher than the December 31, 1997 net income of $1,386,000 and 13.2% higher
than the December 31, 1996 net income of $1,282,000.

     The Bank adopted SFAS No. 130, "Reporting Comprehensive Income," as of
January 1, 1998. Accounting principles generally require that recognized
revenue, expenses, gains and losses be included in net income. Although certain
changes in assets and liabilities, such as unrealized gains and losses on
available for sale securities, are reported as a separate component of the
equity section of the balance sheet, such items, along with net income, are
components of

                                       70
<PAGE>   77
comprehensive income. The adoption of SFAS No. 130 had no effect on the Bank's
net income or stockholders' equity. Comprehensive income for the first nine
months of 1999 was a net loss of $115,000, compared to net income of $1,472,000
for the first nine months of 1998. Comprehensive income for December 31, 1998,
1997 and 1996 was $1,654,000, $1,640,000 and $1,395,000, respectively.

Net Interest Income
- -------------------

     Net interest income at September 30, 1999 of $3,261,000 was $28,000 less
than the September 30, 1998 net interest income of $3,289,000. Interest income
decreased $320,000 during this period primarily as a result of a reduction in
investment securities interest income. Investment securities interest income was
reduced due to a decrease in both the portfolio volume and the yield. The
reduction in other earning assets interest income was the result of lower
yields. Interest expense decreased $292,000 during this period. This reduction
was the result of lower rates experienced in all interest-bearing liability
categories.

     Taxable-equivalent net interest income was $3,623,000 for the first nine
months of 1999, compared to $3,539,000 for the same period in 1998, an $84,000
or 2.37% increase. The change in net interest income on a tax-equivalent basis
is primarily the result of both the decrease in interest expense and the
increase in the nontaxable investment portfolio interest income during this
period. The net interest margin for the first nine months of 1999 and 1998 was
3.90% and 3.81%, respectively.

     The tax-equivalent interest income at December 31, 1998 of $4,741,000 was
higher than both the December 31, 1997 and 1996 tax-equivalent net interest
income of $4,652,000 and $4,414,000, respectively. The net interest margin for
the twelve-month period ending December 31, 1998 of 3.82% was lower the 3.88% at
December 31, 1997 and the 3.87% at December 31, 1996. The lower 1998 net
interest margin is the result of higher interest rates paid on deposits in 1998,
compared to 1997 and 1996.

     For analytical purposes, the following table reflects tax-equivalent net
interest income in recognition of the income tax savings on tax-exempt items
such as interest on municipal securities and tax-exempt loans. Adjustments are
made using a statutory federal tax rate of 34%.

(1) The interest earned on nontaxable investment securities and loans is shown
on a tax equivalent basis.

Provision for Loan Losses
- -------------------------

     The provision for loan losses for the first nine months of 1999 was
$39,000, compared to $44,000 for the same period in 1998. The Bank experienced a
$7,000 net recovery of loans during the first nine months of 1999, compared to a
net charge off of $17,000 during the same period in 1998. The provision for loan
losses for the year ended December 31, 1998, 1997 and 1996 were $58,000, $62,000
and $81,000, respectively.

Other Income
- ------------

     Other income for the first nine months of 1999 of $362,000 did not change
from the same period in 1998. A decrease in customer service fees during the
first nine months of 1999 was offset by increases in net realized gains on sales
of securities and other income. Other income for the entire year of 1998 of
$511,000 was $140,000 higher than the 1997 other income of $371,000, and
$156,000 higher than the 1996 other income of $355,000.

Other Operating Expenses
- ------------------------

     Other operating expenses of $2,457,000 for the first nine months of 1999,
was $224,000 higher than the same period in 1998. This rise was the result of
increases in all other operating expense categories. Other operating expenses
for the entire year of 1998 of $3,037,000, was $141,000 and $229,000 higher than
the 1997 and 1996 other operating expenses.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - In the opinion of management, the accompanying unaudited consolidated
financial statements contain all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the financial position of
Citizens Bank and Trust Company (or the "Bank"), as of September 30, 1999, the
results of its operations for the nine month periods ended September 30, 1999
and 1998 and the cash flows for the nine month periods ended September 30, 1999
and 1998. It is suggested that these unaudited financial statements be read in
conjunction with the audited financial statements of the Bank and the notes
thereto set forth in the Bank's 1998 annual report.

The results of operations for the nine month periods ending September 30, 1999
and 1998 are not necessarily indicative of the results to be expected for the
full year.

NOTE 2 - Income tax expense is less than the amount calculated using the
statutory tax rate, primarily the result of tax exempt income earned from state
and municipal securities, loans and bank-owned life insurance.

NOTE 3 - On January 1, 1998, the Bank adopted the Financial Accounting Standards
Board issued SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130
establishes standards to provide prominent disclosure of comprehensive income
items. Comprehensive income is the change in equity of a business enterprise
during a period from transactions and other events and circumstances from
non-owner sources. Other comprehensive income consists of net unrealized gains
(losses) on available for sale investment securities. Subsequent to the adoption
date, all prior-period amounts are required to be restated to conform to the
provision of SFAS No. 130. The adoption of SFAS No. 130 did not have a material
impact on the corporation's financial position or results of operation.

NOTE 4 - On January 1, 1998, the corporation adopted the Financial Accounting
Standards Board issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 131 requires that public business
enterprises report certain information about operating segments in complete sets
of financial statements of the enterprise and in condensed financial statements
of interim periods issued to shareholders. It also requires that public business
enterprises report certain information about their products and services, the
geographic areas in which they operate and their major customers. Management has
determined that under current conditions, the Bank will report one business
segment.

NOTE 5 - In June 1998, the Financial Accounting standard Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activity." SFAS No. 133 establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments imbedded in other contracts, and for hedging activities.
It requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. If certain conditions are met, a derivative may be specifically
designated as a hedge. The accounting for changes in the fair value of
derivative (gains and losses) depends on the intended use of the derivative and
resulting designation. During July 1999, FASB issued SFAS No. 137 delaying the
effective date of this statement for all fiscal quarters of fiscal years
beginning after June 15, 2000. Earlier application is permitted only as of the
beginning of any fiscal quarter.

To the Board of Directors
Citizens Bank and Trust Company
Palmerton, Pennsylvania


        We have audited the accompanying balance sheets of Citizens Bank and
Trust Company as of December 31, 1998 and 1997, and the related statements of
income, stockholders' equity and cash flows for the years then ended. These
financial statements are the responsibility of the Bank's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.


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


        In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Citizens Bank and
Trust Company as of December 31, 1998 and 1997, and the results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

SIGNIFICANT ACCOUNTING POLICIES

         Nature of operations:

                  The Bank operates under a state bank charter and provides full
                  banking services, including trust services. As a state bank,
                  the Bank is subject to regulations of the Pennsylvania
                  Department of Banking and the Federal Deposit Insurance
                  Corporation. The area served by the Bank is principally
                  Carbon, Monroe and Northampton Counties, Pennsylvania.

         Estimates:

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

         Presentation of cash flows:

                  For purposes of reporting cash flows, cash and cash
                  equivalents include cash on hand, amounts due from banks and
                  interest bearing demand deposits with banks.

         Trust assets:

                  Assets of the trust department, other than trust cash on
                  deposit at the Bank, are not included in these financial
                  statements because they are not assets of the Bank.

         Securities:

                  Securities classified as available for sale are those
                  securities that the Bank intends to hold for an indefinite
                  period of time but not necessarily to maturity. Any decision
                  to sell a security classified as available for sale would be
                  based on various factors, including significant movement in
                  interest rates, changes in maturity mix of the Bank's assets
                  and liabilities, liquidity needs, regulatory capital
                  considerations and other similar factors. Securities available
                  for sale are carried at fair value. Unrealized gains and
                  losses are reported as increases or decreases in other
                  comprehensive income, net of the related deferred tax effect.
                  Realized gains or losses, determined on the basis of the cost
                  of the specific securities sold, are included in earnings.
                  Premiums and discounts are recognized in interest income using
                  the interest method over the period to maturity.

                  Securities classified as held to maturity are those debt
                  securities the Bank has both the intent and ability to hold to
                  maturity regardless of changes in market conditions, liquidity
                  needs or changes in general economic conditions. These
                  securities are carried at cost adjusted for the amortization
                  of premium and accretion of discount, computed by the interest
                  method over their contractual lives.

                  Management determines the appropriate classification of debt
                  securities at the time of purchase and re-evaluates such
                  designation as of each balance sheet date.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         Loans receivable:

                  Loans generally are stated at their outstanding unpaid
                  principal balances, net of an allowance for loan losses and
                  any deferred fees or costs. Interest income is accrued on the
                  unpaid principal balance. Loan origination fees, net of
                  certain direct origination costs, are deferred and recognized
                  as an adjustment of the yield (interest income) of the related
                  loans. The Bank is generally amortizing these amounts over the
                  contractual life of the loan.

                  A loan is generally considered impaired when it is probable
                  the Bank will be unable to collect all contractual principal
                  and interest payments due in accordance with the terms of the
                  loan agreement. The accrual of interest is discontinued when
                  management has serious doubts about further collectibility of
                  principal or interest. A loan may remain on accrual status if
                  it is in the process of collection and is either guaranteed or
                  well secured. When a loan is placed on nonaccrual status,
                  unpaid interest credited to income in the current year is
                  reversed and unpaid interest accrued in prior years is charged
                  against the allowance for loan losses. Interest received on
                  nonaccrual loans generally is either applied against principal
                  or reported as interest income, according to management's
                  judgment as to the collectibility of principal. Generally,
                  loans are restored to accrual status when the obligation is
                  brought current, has performed in accordance with the
                  contractual terms for a reasonable period of time and the
                  ultimate collectibility of the total contractual principal and
                  interest is no longer in doubt.

         Allowance for loan losses:

                  The allowance for loan losses is established through
                  provisions for loan losses charged against income. Loans
                  deemed to be uncollectible are charged against the allowance
                  for loan losses, and subsequent recoveries, if any, are
                  credited to the allowance.

                  The allowance for loan losses related to impaired loans that
                  are identified for evaluation is based on discounted cash
                  flows using the loan's initial effective interest rate or the
                  fair value of the collateral for certain collateral dependent
                  loans.

                  The allowance for loan losses is maintained at a level
                  considered adequate to provide for losses that can be
                  reasonably anticipated. Management's periodic evaluation of
                  the adequacy of the allowance is based on the Bank's past loan
                  loss experience, known and inherent risks in the portfolio,
                  adverse situations that may affect the borrower's ability to
                  repay, the estimated value of any underlying collateral,
                  composition of the loan portfolio, current economic conditions
                  and other relevant factors. This evaluation is inherently
                  subjective as it requires material estimates that may be
                  susceptible to significant change.

         Bank premises and equipment:

                  Bank premises and equipment are stated at cost less
                  accumulated depreciation. Depreciation is computed on
                  straight-line and accelerated methods over their estimated
                  useful lives.

         Advertising costs:

                  The Bank follows the policy of charging the costs of
                  advertising to expense as incurred.

         Income taxes:

                  Deferred taxes are provided on the liability method whereby
                  deferred tax assets are recognized for deductible temporary
                  differences and deferred tax liabilities are recognized for
                  taxable temporary differences. Temporary differences are the
                  differences between the reported amounts of assets and
                  liabilities and their tax basis. Deferred tax assets are
                  reduced by a valuation allowance when, in the opinion of
                  management, it is more likely than not that some portion of
                  the deferred tax assets will not be realized. Deferred tax
                  assets and liabilities are adjusted for the effects of changes
                  in tax laws and rates on the date of enactment.

         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 and letters of credit. Such
                  financial instruments are recorded in the balance sheet when
                  they are funded.

         New accounting standard:

                  The Financial Accounting Standards Board issued Statement No.
                  133, "Accounting for Derivative Instruments and Hedging
                  Activities", in June 1998. The Bank is required to adopt the
                  Statement on January 1, 2000. The adoption of the Statement is
                  not expected to have a significant impact on the financial
                  condition or results of operations of the Bank.

OTHER BORROWED FUNDS

        In 1998, the Bank opened a U.S. Treasury tax and loan note option
        account for the deposit of withholding taxes, corporate income taxes and
        certain other payments to the federal government. Deposits are subject
        to withdrawal and are evidenced by an open-ended interest-bearing note.
        Borrowings under this note option account were $939,338 at December 31,
        1998, with interest payable at a variable rate (4.12% at December 31,
        1998).

COMPREHENSIVE INCOME

        The Bank adopted SFAS No. 130, "Reporting Comprehensive Income," as of
        January 1, 1998. Accounting principles generally require that recognized
        revenue, expenses, gains and losses be included in net income. Although
        certain changes in assets and liabilities, such as unrealized gains and
        losses on available for sale securities, are reported as a separate
        component of the equity section of the balance sheet, such items, along
        with net income, are components of comprehensive income. The adoption of
        SFAS No. 130 had no effect on the Bank's net income or stockholders'
        equity.

        The components of other comprehensive income and related tax effect for
        the years ended December 31, 1998 and 1997 are as follows:

LEASE COMMITMENTS AND TOTAL RENTAL EXPENSE

        The Bank leases a branch office under an operating lease with a lease
        term of five years expiring on February 28, 1999 with current monthly
        payments of $1,516. The lease contains an escalation provision subject
        to increases in real estate taxes paid by the lessor. The Bank is
        responsible to pay certain utilities and maintenance and repairs during
        the term of the lease.

        The Bank also leases land upon which it constructed a branch office. The
        lease expires in January 2006 and requires current monthly payments of
        $2,534 and contains one 10-year renewal option and one 5-year renewal
        option. The lease contains an escalation provision subject to increases
        in the Consumer Price Index.

        The total rental expense included in the income statements was $49,044
        and $48,611 for the years ended December 31, 1998 and 1997
        respectively.

        Future minimum lease payments by year and in the aggregate, under

EMPLOYEE BENEFITS (CONTINUED)

     Deferred supplemental income plan:

        The Bank has adopted various deferred compensation plans for certain
        directors and officers of the Bank. Under the Plans' provisions,
        benefits will be payable upon retirement, death or permanent disability
        of the participant. At December 31, 1998 and 1997, $614,426 and $541,725
        respectively had been accrued under these contracts. To fund the
        benefits under these agreements, the Bank is the owner and the
        beneficiary of life insurance policies on the lives of the directors and
        officers. The policies had an aggregate cash surrender value of $359,379
        and $301,504 at December 31, 1998 and 1997 respectively.

TRANSACTIONS WITH DIRECTORS, PRINCIPAL STOCKHOLDERS AND
EXECUTIVE OFFICERS

        The Bank has had, and may be expected to have in the future, banking
        transactions in the ordinary course of business with its directors,
        principal stockholders, executive officers and their related interests,
        on the same terms, including interest rates and collateral, as those
        prevailing at the time for comparable transactions with others. These
        persons were indebted to the Bank for loans totaling approximately
        $440,000 and $206,000 at December 31, 1998 and 1997 respectively. During
        1998, $407,000 of new loans were made and repayments totaled $173,000.

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 needs of its
        customers. These financial instruments include commitments to extend
        credit and letters of credit. Those instruments involve, to varying
        degrees, elements of credit risk in excess of the amount recognized in
        the balance sheet.

        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 letters of credit 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.

        A summary of the Bank's financial instrument commitments at December 31,
        1998 and 1997 is as follows:

Outstanding letters of credit                        42,000           10,000
</TABLE>

        Commitments to extend credit are agreements to lend to a customer as
        long as there is no violation of any condition established in the
        contract. Since many of the commitments are expected to expire without
        being drawn upon, the total commitment amounts do not necessarily
        represent future cash requirements. Commitments generally have fixed
        expiration dates or other termination clauses and may require payment of
        a fee. The Bank evaluates each customer's credit worthiness 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. Collateral held varies but may include personal or
        commercial real estate, accounts receivable, inventory and equipment.

        Outstanding letters of credit written are conditional commitments issued
        by the Bank to guarantee the performance of a customer to a third party.
        The credit risk involved in issuing letters of credit is essentially the
        same as that involved in extending other loan commitments.

CONCENTRATION OF CREDIT RISK

        The Bank grants commercial, residential and consumer loans to customers
        primarily located in Carbon, Monroe and Northampton Counties,
        Pennsylvania. The concentrations of credit by type of loan are set forth
        in Note 3. Although the Bank has a diversified loan portfolio, its
        debtors' ability to honor their contracts is influenced by the region's
        economy.

REGULATORY MATTERS

        The Bank is required to maintain cash reserve balances in vault cash or
        with the Federal Reserve Bank. The total of those reserve balances was
        approximately $460,000 at December 31, 1998.


        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 (set
        forth below) of total and Tier 1 capital (as defined in the regulations)
        to risk-weighted assets, and of Tier 1 capital to average assets.
        Management believes, as of December 31, 1998, that the Bank meets all
        capital adequacy requirements to which it is subject.

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

        The Bank is subject to certain restrictions on the amount of dividends
        that it may declare without prior regulatory approval. At December 31,
        1998, approximately $11,950,000 of retained earnings were available for
        dividend declaration without prior regulatory approval.

        During 1998, the Bank received approval to repurchase up to 600 shares
        of stock. As of December 31, 1998, 415 shares have been repurchased and
        retired.

FAIR VALUE OF FINANCIAL INSTRUMENTS

        Management uses its best judgment in estimating the fair value of the
        Bank's financial instruments; however, there are inherent weaknesses in
        any estimation technique. Therefore, for substantially all financial
        instruments, the fair value estimates herein are not necessarily
        indicative of the amounts the Bank could have realized in a sales
        transaction on the dates indicated. The estimated fair value amounts
        have been measured as of their respective year ends, and have not been
        reevaluated or updated for purposes of these financial statements
        subsequent to those respective dates. As such, the estimated fair values
        of these financial instruments subsequent to the respective reporting
        dates may be different than the amounts reported at each year end.

FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

        The following information should not be interpreted as an estimate of
        the fair value of the entire Bank since a fair value calculation is only
        provided for a limited portion of the Bank's assets. Due to a wide range
        of valuation techniques and the degree of subjectivity used in making
        the estimates, comparisons between the Bank's disclosures and those of
        other companies may not be meaningful. The following methods and
        assumptions were used to estimate the fair values of the Bank's
        financial instruments at December 31, 1998 and 1997:

                  Cash and cash equivalents and federal funds sold:

                           The carrying amounts of cash and short-term
                           instruments approximate their fair value.

                  Securities:

                           Fair values for securities equal quoted market price,
                           if available. If a quoted market price is not
                           available, fair value is estimated using quoted
                           market prices for similar securities.

                  Loans receivable:

                           The fair value of loans is estimated by discounting
                           the future cash flows using the current rates at
                           which similar loans would be made to borrowers with
                           similar credit ratings and for the same remaining
                           maturities.

                  Accrued interest receivable:

                           The carrying amount of accrued interest receivable
                           approximates fair value.

                  Deposit liabilities and securities sold under agreements to
                  repurchase:

                           The fair value of demand deposits, savings accounts,
                           certain money market deposits and securities sold
                           under agreements to repurchase is the amount payable
                           on demand at the reporting date. The fair value of
                           fixed-maturity certificates of deposit is estimated
                           using the rates currently offered for deposits of
                           similar remaining maturities.

                  Other borrowed funds:

                           The current carrying amounts of other borrowed funds
                           approximate their fair values.

                  Accrued interest payable:

                           The carrying amount of accrued interest payable
                           approximates fair value.

                  Off-balance sheet instruments:

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

To the Board of Directors
Citizens Bank and Trust Company
Palmerton, Pennsylvania


      We have audited the accompanying balance sheets of Citizens Bank and Trust
Company as of December 31, 1997 and 1996, and the related statements of income,
stockholders' equity and cash flows for the years then ended. These financial
statements are the responsibility of the Bank's management. Our responsibility
is to express an opinion on these financial statements based on our audits.


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


      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Citizens Bank and Trust
Company as of December 31, 1997 and 1996, and the results of its operations and
its cash flows for the years then ended in conformity with generally accepted
accounting principles.

SIGNIFICANT ACCOUNTING POLICIES

         Nature of operations:

                  The Bank operates under a state bank charter and provides full
         banking services, including trust services. As a state bank, the Bank
         is subject to regulations of the Pennsylvania Department of Banking and
         the Federal Deposit Insurance Corporation. The area served by the Bank
         is principally Carbon, Monroe and Northampton Counties, Pennsylvania.

         Estimates:

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

         Presentation of cash flows:

                  For purposes of reporting cash flows, cash and cash
         equivalents include cash on hand, amounts due from banks and interest
         bearing demand deposits with banks.

         Trust assets:

                  Assets of the trust department, other than trust cash on
         deposit at the Bank, are not included in these financial statements
         because they are not assets of the Bank.

         Securities:

                  Securities classified as available for sale are those
         securities that the Bank intends to hold for an indefinite period of
         time but not necessarily to maturity. Any decision to sell a security
         classified as available for sale would be based on various factors,
         including significant movement in interest rates, changes in maturity
         mix of the Bank's assets and liabilities, liquidity needs, regulatory
         capital considerations and other similar factors. Securities available
         for sale are carried at fair value. Unrealized appreciation and
         depreciation are reported as increases or decreases in stockholders'
         equity, net of the related deferred tax effect. Realized gains or
         losses, determined on the basis of the cost of the specific securities
         sold, are included in earnings. Premiums and discounts are recognized
         in interest income using the interest method over the period to
         maturity.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Securities (continued):

         Securities classified as held to maturity are those debt securities the
         Bank has both the intent and ability to hold to maturity regardless of
         changes in market conditions, liquidity needs or changes in general
         economic conditions. These securities are carried at cost adjusted for
         the amortization of premium and accretion of discount, computed by the
         interest method over their contractual lives.

         Management determines the appropriate classification of debt securities
         at the time of purchase and re-evaluates such designation as of each
         balance sheet date.

Loans receivable:

         Loans generally are stated at their outstanding unpaid principal
         balances, net of an allowance for loan losses and any deferred fees or
         costs. Interest income is accrued on the unpaid principal balance. Loan
         origination fees, net of certain direct origination costs, are deferred
         and recognized as an adjustment of the yield (interest income) of the
         related loans. The Bank is generally amortizing these amounts over the
         contractual life of the loan.

         A loan is generally considered impaired when it is probable the Bank
         will be unable to collect all contractual principal and interest
         payments due in accordance with the terms of the loan agreement. The
         accrual of interest is discontinued when management has serious doubts
         about further collectibility of principal or interest. A loan may
         remain on accrual status if it is in the process of collection and is
         either guaranteed or well secured. When a loan is placed on nonaccrual
         status, unpaid interest credited to income in the current year is
         reversed and unpaid interest accrued in prior years is charged against
         the allowance for loan losses. Interest received on nonaccrual loans
         generally is either applied against principal or reported as interest
         income, according to management's judgment as to the collectibility of
         principal. Generally, loans are restored to accrual status when the
         obligation is brought current, has performed in accordance with the
         contractual terms for a reasonable period of time and the ultimate
         collectibility of the total contractual principal and interest is no
         longer in doubt.

Allowance for loan losses:

                  The allowance for loan losses is established through
         provisions for loan losses charged against income. Loans deemed to be
         uncollectible are charged against the allowance for loan losses, and
         subsequent recoveries, if any, are credited to the allowance.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Allowance for loan losses (continued):

                  The allowance for loan losses related to impaired loans that
         are identified for evaluation is based on discounted cash flows using
         the loan's initial effective interest rate or the fair value of the
         collateral for certain collateral dependent loans.

                  The allowance for loan losses is maintained at a level
         considered adequate to provide for losses that can be reasonably
         anticipated. Management's periodic evaluation of the adequacy of the
         allowance is based on the Bank's past loan loss experience, known and
         inherent risks in the portfolio, adverse situations that may affect the
         borrower's ability to repay, the estimated value of any underlying
         collateral, composition of the loan portfolio, current economic
         conditions and other relevant factors. This evaluation is inherently
         subjective as it requires material estimates that may be susceptible to
         significant change.

Bank premises and equipment:

                  Bank premises and equipment are stated at cost less
         accumulated depreciation. Depreciation is computed on straight-line and
         accelerated methods over their estimated useful lives.

Income taxes:

                  Deferred taxes are provided on the liability method whereby
         deferred tax assets are recognized for deductible temporary differences
         and deferred tax liabilities are recognized for taxable temporary
         differences. Temporary differences are the differences between the
         reported amounts of assets and liabilities and their tax basis.
         Deferred tax assets are reduced by a valuation allowance when, in the
         opinion of management, it is more likely than not that some portion of
         the deferred tax assets will not be realized. Deferred tax assets and
         liabilities are adjusted for the effects of changes in tax laws and
         rates on the date of enactment.

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 and letters of credit. Such financial instruments are
         recorded in the balance sheet when they are funded.

EMPLOYEE BENEFITS (CONTINUED)

     Deferred supplemental income plan:
          The Bank has adopted various deferred compensation plans for certain
          directors and officers of the Bank. Under the Plans' provisions,
          benefits will be payable upon retirement, death or permanent
          disability of the participant. At December 31, 1997 and 1996,
          $541,725 and $ 476,812 respectively had been accrued under these
          contracts. To fund the benefits under these agreements, the Bank is
          the owner and the beneficiary of life insurance policies on the lives
          of the directors and officers. The policies had an aggregate cash
          surrender value of $ 301,504 and $ 256,600 at December 31, 1997 and
          1996 respectively.

TRANSACTIONS WITH DIRECTORS, PRINCIPAL STOCKHOLDERS AND EXECUTIVE OFFICERS

     The Bank has had, and may be expected to have in the future, banking
     transactions in the ordinary course of business with its directors,
     principal stockholders, executive officers and their related interests, on
     the same terms, including interest rates and collateral, as those
     prevailing at the time for comparable transactions with others. These
     persons were indebted to the Bank for loans totaling approximately
     $206,000 and $ 242,000 at December 31, 1997 and 1996 respectively.

     An analysis of the activity with respect to such loans to related parties
     for the years ended December 31, 1997 and 1996 is as follows:

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 needs of its customers.
     These financial instruments include commitments to extend credit and
     letters of credit. Those instruments involve, to varying degrees, elements
     of credit risk in excess of the amount recognized in the balance sheet.

     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 letters of credit 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.

     A summary of the Bank's financial instrument commitments at December 31,
     1997 and 1996 is as follows:

                                                     ----------      ----------
         <S>                                         <C>             <C>
         Commitments to extend credit                $4,416,000      $3,792,000
         Outstanding letters of credit                   10,000         102,000
</TABLE>


     Commitments to extend credit are agreements to lend to a customer as long
     as there is no violation of any condition established in the contract.
     Since many of the commitments are expected to expire without being drawn
     upon, the total commitment amounts do not necessarily represent future cash
     requirements. Commitments generally have fixed expiration dates or other
     termination clauses and may require payment of a fee. The Bank evaluates
     each customer's credit worthiness 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. Collateral held varies
     but may include personal or commercial real estate, accounts receivable,
     inventory and equipment.

     Outstanding letters of credit written are conditional commitments issued by
     the Bank to guarantee the performance of a customer to a third party. The
     credit risk involved in issuing letters of credit is essentially the same
     as that involved in extending other loan commitments.

CONCENTRATION OF CREDIT RISK

     The Bank grants commercial, residential and consumer loans to customers
     primarily located in Carbon, Monroe and Northampton Counties, Pennsylvania.
     The concentrations of credit by type of loan are set forth in Note 3.
     Although the Bank has a diversified loan portfolio, its debtors' ability to
     honor their contracts is influenced by the region's economy.

REGULATORY MATTERS

     The Bank is required to maintain cash reserve balances in vault cash or
     with the Federal Reserve Bank. The total of those reserve balances was
     approximately $ 405,000 at December 31, 1997.

     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 affect 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 (set forth below)
     of total and Tier 1 capital (as defined in the regulations) to
     risk-weighted assets, and of Tier 1 capital to average assets. Management
     believes, as of December 31, 1997, that the Bank meets all capital adequacy
     requirements to which it is subject.

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

FAIR VALUE OF FINANCIAL INSTRUMENTS

     Management uses its best judgment in estimating the fair value of the
     Bank's financial instruments; however, there are inherent weaknesses in any
     estimation technique. Therefore, for substantially all financial
     instruments, the fair value estimates herein are not necessarily indicative
     of the amounts the Bank could have realized in a sales transaction on the
     dates indicated. The estimated fair value amounts have been measured as of
     their respective year ends, and have not been reevaluated or updated for
     purposes of these financial statements subsequent to those respective
     dates. As such, the estimated fair values of these financial instruments
     subsequent to the respective reporting dates may be different than the
     amounts reported at each year end.

FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

     The following information should not be interpreted as an estimate of the
     fair value of the entire bank since a fair value calculation is only
     provided for a limited portion of the Bank's assets. Due to a wide range of
     valuation techniques and the degree of subjectivity used in making the
     estimates, comparisons between the Bank's disclosures and those of other
     companies may not be meaningful. The following methods and assumptions were
     used to estimate the fair values of the Bank's financial instruments at
     December 31, 1997 and 1996:

          Cash and cash equivalents and federal funds sold:
               The carrying amounts of cash and short-term instruments
               approximate their fair value.

          Securities:
               Fair values for securities equal quoted market price, if
               available. If a quoted market price is not available, fair value
               is estimated using quoted market prices for similar securities.

          Loans receivable:
               The fair value of loans is estimated by discounting the future
               cash flows using the current rates at which similar loans would
               be made to borrowers with similar credit ratings and for the same
               remaining maturities.

          Accrued interest receivable:
               The carrying amount of accrued interest receivable approximates
               fair value.

          Deposit liabilities and securities sold under agreements to
          repurchase:
               The fair value of demand deposits, savings accounts, certain
               money market deposits and securities sold under agreements to
               repurchase is the amount payable on demand at the reporting date.
               The fair value of fixed-maturity certificates of deposit is
               estimated using the rates currently offered for deposits of
               similar remaining maturities.

          Accrued interest payable:
               The carrying amount of accrued interest payable approximates fair
               value.

          Off-balance sheet instruments:
               The fair value of commitments to extend credit and for
               outstanding letters of credit is estimated using the fees
               currently charged to enter into similar agreements.

                         EXCHANGE OF STOCK CERTIFICATES

SECTION 2.1 Conversion of Shares.

         On the Effective Date (as defined in Section 9.2 of this Agreement) the
shares of CBTC Common Stock (defined below) then outstanding shall be converted
into shares of HNC Common Stock (defined below), as follows:

         (a)      General. Subject to the provisions of this Article II, each
                  share of CBTC Common Stock, par value $50.00 per share ("CBTC
                  Common Stock") issued and outstanding immediately before the
                  Effective Date (other than shares of CBTC Common Stock then
                  owned by HNC or any direct or indirect subsidiary of HNC,
                  other than trust account shares or shares acquired in
                  connection with debts previously contracted) shall, on the
                  Effective Date, be converted into and become, without any
                  action on the part of the holder thereof, the right to receive
                  166 shares of HNC Common Stock, par value, $1.00 per share
                  ("HNC Common Stock") (the "Exchange Ratio"). Subject to the
                  provisions of Section 2.1(b), the aggregate number of shares
                  of HNC Common Stock to be issued under this Agreement shall
                  not exceed 919,972 shares and the Exchange Ratio shall be 166.

         (b)      Anti-dilution Provision. In the event that HNC shall at any
                  time before the Effective Date: (i) declare or pay a dividend
                  in shares of HNC Common Stock, (ii) combine the outstanding
                  shares of HNC Common Stock into a smaller number of shares, or
                  (iii) subdivide the outstanding shares of HNC Common Stock
                  into a greater number of shares, or (iv) reclassify the shares
                  of HNC stock, then the Exchange Ratio shall be proportionately
                  adjusted accordingly.

         (c)      No Fractional Shares. No fractional shares of HNC Common
                  Stock, and no scrip or certificates therefor, shall be issued
                  in connection with the Bank Merger. In lieu of the issuance of
                  any fractional share to which he would otherwise be entitled,
                  each former shareholder of CBTC shall receive in cash an
                  amount equal to the fair market value of his fractional
                  interest, which fair market value shall be determined by
                  multiplying such fraction by the Closing Market Price (as
                  defined in Section 2.1(d) of this Article II).

         (d)      Closing Market Price. For purposes of this Agreement, the
                  Closing Market Price

                                      A-2
<PAGE>   141
                  shall be the arithmetic average of the per share closing
                  prices for HNC Common Stock for the twenty (20) trading days
                  immediately preceding the date which is five (5) business days
                  before the Effective Date, as reported on the National Market
                  System of the National Association of Securities Dealers
                  Automated Quotation System (NASDAQ/NMS), the foregoing twenty
                  (20) trading days being hereinafter sometimes referred to as
                  the "Price Determination Period". (For example, if November 1,
                  1999 were to be the Effective Date, then the Price
                  Determination Period would be September 27, 28, 29, 30,
                  October 1, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 18, 19, 20, 21,
                  22, 1999.) In the event that NASDAQ/NMS shall fail to report a
                  closing price for HNC Common Stock for any trading day during
                  the Price Determination Period, then the closing price for
                  that day shall be equal to the average of the closing bid
                  price and the closing asked price as quoted on NASDAQ/NMS for
                  that day. In the event that NASDAQ/NMS shall fail to report a
                  closing price, closing bid price and closing asked price,
                  respectively, for HNC Common Stock for any trading day during
                  the Price Determination Period, then the closing price for
                  that day shall be equal to the average of the closing bid
                  prices and the closing asked prices as quoted: (i) by two
                  market makers in HNC Common Stock listed in HNC's 1999 Annual
                  Report to Shareholders; or, in the event that neither of these
                  firms is then making a market in HNC Common Stock, (ii) by two
                  brokerage firms then making a market in HNC Common Stock to be
                  selected by HNC and approved by CBTC.

         (e)      CBTC Treasury Stock. Each share of CBTC Common Stock issued
                  and held in the treasury of CBTC as of the Effective Date, if
                  any, shall be canceled, and no cash, stock, or other property
                  shall be delivered in exchange therefor.

         (f)      CBTC Common Stock held by HNC. Each share of CBTC Common Stock
                  (other than trust account shares or shares acquired in
                  connection with debts previously contracted) owned by HNC or
                  any direct or indirect subsidiary of HNC on the Effective
                  Date, if any, shall be cancelled.

         (g)      HNC Common Stock.

                  (i)          Each share of HNC Common Stock issued and
                               outstanding immediately prior to the Effective
                               Date, shall, on and after the Effective Date,
                               continue to be issued and outstanding as an
                               identical share of HNC Common Stock.

                  (ii)         Each share of HNC Common Stock issued and held in
                               the treasury of HNC as of the Effective Date, if
                               any, shall, on and after the Effective Date,
                               continue to be issued and held in the treasury of
                               HNC.

SECTION 2.2 Exchange of Stock Certificates.

                                      A-3
<PAGE>   142
         CBTC Common Stock certificates shall be exchanged for HNC Common Stock
certificates in accordance with the following procedures:

         (a)      Exchange Agent. The transfer agent of HNC shall act as
                  exchange agent (the "Exchange Agent") to receive CBTC Common
                  Stock certificates from the holders thereof and to exchange
                  such stock certificates for HNC Common Stock certificates and
                  (if applicable) to pay cash for fractional shares of CBTC
                  Common Stock pursuant to Section 2.1(d) above. The Exchange
                  Agent shall, on or promptly after the Effective Date, mail to
                  each former shareholder of CBTC a notice specifying the
                  procedures to be followed in surrendering such shareholder's
                  CBTC Common Stock certificates.

         (b)      Surrender of Certificates. As promptly as possible after
                  receipt of the Exchange Agent's notice, each former
                  shareholder of CBTC shall surrender his CBTC Common Stock
                  certificates to the Exchange Agent; provided, that if any
                  former shareholder of CBTC shall be unable to surrender his
                  CBTC Common Stock certificates due to loss or mutilation
                  thereof, he may make a constructive surrender by following
                  procedures comparable to those customarily used by HNC for
                  issuing replacement certificates to HNC shareholders whose HNC
                  Common Stock certificates have been lost or mutilated. Upon
                  receiving a proper actual or constructive surrender of CBTC
                  Common Stock certificates from a former CBTC shareholder, the
                  Exchange Agent shall issue to such shareholder, in exchange
                  therefor, a HNC Common Stock certificate representing the
                  whole number of shares of HNC Common Stock into which such
                  shareholder's shares of CBTC Common Stock have been converted
                  in accordance with this Article II, together with a check in
                  the amount of any cash to which such shareholder is entitled,
                  pursuant to Section 2.1(c) of this Agreement, in lieu of the
                  issuance of a fractional share.

         (c)      Dividend Withholding. Dividends, if any, payable by HNC after
                  the Effective Date to any former shareholder of CBTC who has
                  not prior to the payment date surrendered his CBTC Common
                  Stock certificates may, at the option of HNC, be withheld. Any
                  dividends so withheld shall be paid, without interest, to such
                  former shareholder of CBTC upon proper surrender of his CBTC
                  Common Stock certificates.

         (d)      Failure to Surrender Certificates. All CBTC Common Stock
                  certificates must be surrendered to the Exchange Agent within
                  two (2) years after the Effective Date. In the event that any
                  former shareholder of CBTC shall not have properly surrendered
                  his CBTC Common Stock certificates within two (2) years after
                  the Effective Date, the shares of HNC Common Stock that would
                  otherwise have been issued to him may, at the option of HNC,
                  be sold and the net proceeds of such sale, together with the
                  cash (if any) to which he is entitled in lieu of the issuance
                  of a fractional share and any previously accrued dividends,
                  shall be held in a non-interest bearing account

                                      A-4
<PAGE>   143
                  for his benefit. From and after any such sale, the sole right
                  of such former shareholder of CBTC shall be the right to
                  collect such net proceeds, cash and accumulated dividends.
                  Subject to all applicable laws of escheat, such net proceeds,
                  cash and accumulated dividends shall be paid to such former
                  shareholder of CBTC, without interest, upon proper surrender
                  of his CBTC Common Stock certificates.

         (e)      Expenses of Share Surrender and Exchange. All costs and
                  expenses associated with the foregoing surrender and exchange
                  procedure shall be borne by HNC. Notwithstanding the
                  foregoing, no party hereto will be liable to any holder of
                  CBTC Common Stock for any amount paid in good faith to a
                  public official or agency pursuant to any applicable abandoned
                  property, escheat or similar law.

         (f)      Exchange Procedures. Each certificate for shares of CBTC
                  Common Stock delivered for exchange under this Article II must
                  be endorsed in blank by the registered holder thereof or be
                  accompanied by a power of attorney to transfer such shares
                  endorsed in blank by such holder. If more than one certificate
                  is surrendered at one time and in one transmittal package for
                  the same shareholder account, the number of whole shares of
                  HNC Common Stock for which certificates will be issued
                  pursuant to this Article II will be computed on the basis of
                  the aggregate number of shares represented by the certificates
                  so surrendered. If shares of CBTC Common Stock or payments of
                  cash are to be issued or made to a person other than the one
                  in whose name the surrendered certificate is registered, the
                  certificate so surrendered must be properly endorsed in blank,
                  with signature(s) guaranteed, or otherwise in proper form for
                  transfer, and the person to whom certificates for shares of
                  HNC Common Stock is to be issued or to whom cash is to be paid
                  shall pay any transfer or other taxes required by reason of
                  such issuance or payment to a person other than the registered
                  holder of the certificate for shares of CBTC Common Stock
                  which are surrendered. As promptly as practicable after the
                  Effective Date, HNC shall send, or cause to be sent, to each
                  shareholder of record of CBTC Common Stock, transmittal
                  materials for use in exchanging certificates representing CBTC
                  Common Stock for certificates representing HNC Common Stock
                  into which the former have been converted in the
                  Reorganization and Bank Merger.

         (g)      Closing of Stock Transfer Books; Cancellation of CBTC
                  Certificates. Upon the Effective Date, the stock transfer
                  books for CBTC Common Stock will be closed and no further
                  transfers of shares of CBTC Common Stock will thereafter be
                  made or recognized. All certificates for shares of CBTC Common
                  Stock surrendered pursuant to this Article II will be canceled
                  by HNC.

         (h)      Rights Evidenced by Certificate. Each certificate for shares
                  of HNC Common Stock issued in exchange for certificates of
                  CBTC Common Stock pursuant to Section 2.2(f) hereof will be
                  dated as of the Effective Date and be entitled to dividends
                  and all other rights and privileges pertaining to such shares
                  of HNC Common Stock from

                                      A-5
<PAGE>   144
                  the Effective Date. Until surrendered, each certificate
                  theretofore evidencing shares of CBTC Common Stock will, from
                  and after the Effective Date, evidence solely the right to
                  receive certificates for shares of HNC Common Stock pursuant
                  to Section 2.2(f) hereof. If certificates for shares of CBTC
                  Common Stock are exchanged for HNC Common Stock at a date
                  following one or more record dates for the payment of
                  dividends or of any other distribution on the shares of HNC
                  Common Stock subsequent to the Effective Date, HNC will pay
                  cash in an amount equal to dividends theretofore payable on
                  such HNC Common Stock and pay or deliver any other
                  distribution to which holders of shares of HNC Common Stock
                  have theretofore become entitled. No interest will accrue or
                  be payable in respect of dividends or cash otherwise payable
                  under this Section 2.2 upon surrender of certificates for
                  shares of HNC Common Stock. Notwithstanding the foregoing, no
                  party hereto will be liable to any holder of CBTC Common Stock
                  for any amount paid in good faith to a public official or
                  agency pursuant to any applicable abandoned property, escheat
                  or similar law. Until such time as certificates for shares of
                  CBTC Common Stock are surrendered by a CBTC shareholder to HNC
                  for exchange, HNC shall have the right to withhold dividends
                  or any other distributions, without interest, on the shares of
                  the HNC Common Stock issuable to such shareholder.

         (i)      Payment Procedures. As soon as practical after the Effective
                  Date, HNC shall make payment of the cash consideration
                  provided for in Section 2.1(c) to each person entitled
                  thereto.

         (j)      Unclaimed Shares. In the event that any certificates for
                  shares of CBTC Common Stock have not been surrendered for
                  exchange in accordance with this Section on or before the
                  second anniversary of the Effective Date, HNC may at any time
                  thereafter, with or without notice to the holders of record of
                  such certificates, sell for the accounts of any or all of such
                  holders any or all of the shares of HNC Common Stock which
                  such holders are entitled to receive under Section 2.1(a)
                  hereof (the "Unclaimed Shares"). Any such sale may be made by
                  public or private sale or sale at any broker's board or on any
                  securities exchange in such manner and at such times as HNC
                  shall determine. If, in the opinion of counsel for HNC, it is
                  necessary or desirable, any Unclaimed Shares may be registered
                  for sale under the Securities Act of 1933, as amended (the
                  "Securities Act") and applicable state laws. HNC shall not be
                  obligated to make any sale of Unclaimed Shares if it shall
                  determine not do so, even if notice of sale of the Unclaimed
                  Shares has been given. The net proceeds of any such sale of
                  Unclaimed Shares shall be held for holders of the
                  unsurrendered certificates for shares of CBTC Common Stock
                  whose Unclaimed Shares have been sold, to be paid to them upon
                  surrender of the certificates for shares of CBTC Common Stock.
                  From and after any such sale, the sole right of the holders of
                  the unsurrendered certificates for shares of CBTC Common Stock
                  whose Unclaimed Shares have been sold shall be the right to
                  collect the net sale proceeds held by HNC for their respective
                  accounts, and such holders shall not be entitled to receive
                  any

                                      A-6
<PAGE>   145
                  interest on such net sale proceeds held by HNC.

SECTION 2.3 Other Matters.

         (a)      Notwithstanding any term of this Agreement to the contrary,
                  HNC shall have the right to cause CBTC to be the Surviving
                  Bank of the Bank Merger described at Section 1.1(a), so long
                  as the exercise of such right does not have a material adverse
                  effect on the interests of the CBTC shareholders or cause a
                  material delay in, or otherwise adversely affect, consummation
                  of the transactions contemplated herein; if such right is
                  exercised, this Agreement shall be deemed to be modified to
                  accord such change.

         (b)      Nothing set forth in this Agreement or any Exhibit hereto
                  shall be construed:

                  (i)          to preclude HNC from acquiring or assuming, or to
                               limit in any way the right of HNC to acquire or
                               assume, prior to or following the Effective Date,
                               the stock, or assets or liabilities of any other
                               financial services institution or other
                               corporation or entity, whether by issuance or
                               exchange of HNC Common Stock, or otherwise;

                  (ii)         to preclude HNC from issuing, or to limit in any
                               way the right of HNC to issue, prior to or
                               following the Effective Date, HNC Common Stock,
                               HNC Preferred Stock or other securities;

                  (iii)        to preclude HNC from granting employee, director
                               or compensatory options at any time with respect
                               to HNC Common Stock, HNC Preferred Stock or other
                               securities;

                  (iv)         to preclude option holders of HNC from exercising
                               options at any time with respect to HNC Common
                               Stock, HNC Preferred Stock or other securities;
                               or

                  (v)          to preclude HNC from taking, or to limit in any
                               way the right of HNC to take, any other action
                               not expressly and specifically prohibited by the
                               terms of this Agreement.


                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

SECTION 3.1 Representations and Warranties of CBTC.

         CBTC represents and warrants to HNC (and the word "it" in this Article
III refers to CBTC

                                      A-7
<PAGE>   146
and each subsidiary of it) that, as of even date herewith and except as
specifically disclosed in the Annex of disclosure schedules included herewith,
as follows:

         (a)      Corporate Organization and Qualification. CBTC is a
                  Pennsylvania chartered bank, duly organized, validly existing
                  and in good standing under the laws of the Commonwealth of
                  Pennsylvania. CBTC has the requisite corporate power and
                  authority (including all federal, state, local and foreign
                  governmental authorizations) to carry on its businesses as now
                  being conducted and to own its properties and assets. Except
                  as disclosed on Annex 3.1(a), CBTC has made available to HNC a
                  complete and correct copy of the charter and bylaws of CBTC
                  and such charter and such bylaws are in full force and effect
                  as of the date hereof.

         (b)      Authorized Capital. The authorized capital stock of CBTC
                  consists of 5,542 shares of CBTC Common Stock all of which
                  were issued and outstanding as of the date of this Agreement.
                  All of the outstanding shares of capital stock of CBTC have
                  been duly authorized and are validly issued, fully paid and
                  nonassessable. CBTC has no shares of capital stock reserved
                  for issuance. CBTC has no outstanding bonds, debentures, notes
                  or other obligations the holders of which have the right to
                  vote (or convertible into or exercisable for securities having
                  the right to vote) with shareholders on any matter. The
                  outstanding shares of capital stock of CBTC have not been
                  issued in violation of any preemptive rights. There are no
                  outstanding subscriptions, options, warrants, rights,
                  convertible securities or other agreements or commitments of
                  any character relating to the issued or unissued capital stock
                  or other securities of CBTC. After the Effective Date, CBTC
                  will have no obligation which is being assumed by HNC which
                  will result in any obligation to issue, transfer or sell any
                  shares of capital stock pursuant to any Employee Plan (as
                  defined in Section 3.1 (n)).

         (c)      Subsidiaries. CBTC has no subsidiaries.

         (d)      Corporate Authority. Subject only to approval of this
                  Agreement by the holders of the number of votes required by
                  applicable law, CBTC's articles of incorporation or bylaws
                  cast by all holders of CBTC Common Stock (without any
                  minority, class or series voting requirement), and, subject to
                  the regulatory approvals specified in Section 6.1(b) hereof,
                  CBTC has the requisite corporate power and authority, and
                  legal right, and has taken all corporate action necessary in
                  order to execute and deliver this Agreement and the Bank
                  Merger Agreement and to consummate the transactions applicable
                  to it contemplated hereby. This Agreement and the Bank Merger
                  Agreement has been duly and validly executed and delivered by
                  CBTC and constitutes the valid and binding obligations of CBTC
                  enforceable against it, in accordance with its terms, except
                  to the extent enforcement is limited by bankruptcy, insolvency
                  and other similar laws affecting creditors' rights or the
                  application by a court of equitable principles.

                                      A-8
<PAGE>   147
         (e)      No Violations. The execution, delivery and performance of this
                  Agreement by it does not, the execution, delivery and
                  performance of the Bank Merger Agreement by it will not, and
                  the consummation of the transactions contemplated hereby by it
                  will not, constitute (i) subject to receipt of the required
                  regulatory approvals specified in Section 6.1(b), a breach or
                  violation of, or a default under, any law, rule or regulation
                  or any judgment, decree, order, governmental permit or
                  license, to which it (or any of its respective properties) is
                  subject, which breach, violation or default would have a
                  Material Adverse Effect on it, or enable any person to enjoin
                  the Bank Merger, (ii) a breach or violation of, or a default
                  under CBTC's articles of incorporation, or its bylaws, or
                  (iii) except as disclosed in Annex 3.1(e), a breach or
                  violation of, or a default under (or an event which with due

                  accepted accounting principles or which are in any case or in

                  liability, other than liabilities of the same nature as those
                  set forth in the Bank Balance Sheet, all of which have been
                  reasonably incurred in the ordinary course of business
                  consistent with customary business practices of prudently
                  managed banks (hereinafter referred to as "Ordinary Course of

                  condition, properties, assets, business, results of
                  operations, resources or personnel or prospects of it which,
                  individually or in the aggregate, has had, or might reasonably
                  be expected to result in, a Material Adverse Effect on it. It

                  determination that would have a Material Adverse Effect on it.

                  matters or any other fact or circumstances of which its
                  management is aware that could reasonably be expected to
                  result in any claims against or obligations or liabilities of
                  it), that, alone or in the aggregate, are reasonably likely to
                  have a Material Adverse Effect on it or to hinder or delay, in

                               seeking to impose, or that could result in the
                               imposition on CBTC of any liability arising under
                               any local, state or federal environmental
                               statute, regulation or ordinance including,

                               Environmental Response, Compensation and
                               Liability Act of 1980, as amended, pending or, to
                               CBTC's knowledge, threatened against CBTC; to
                               CBTC's knowledge, there is no reasonable basis
                               for any such proceeding, claim, action or
                               governmental investigation; and CBTC is not
                               subject to any agreement, order, judgment, decree
                               or memorandum by or with any court, governmental
                               authority, regulatory agency or third party
                               imposing any such liability.

         (s)      Allowance. The allowance for loan and lease losses shown on
                  CBTC's consolidated statement of financial condition as of
                  December 31, 1998 was, and the allowance for loan and lease
                  losses shown on CBTC's consolidated statement of financial
                  condition for periods ending after the date of this Agreement
                  will be, in the opinion of management of CBTC, adequate, as of
                  the date thereof, under generally accepted accounting
                  principles applicable to commercial banks and all other
                  applicable regulatory requirements for all losses reasonably
                  anticipated in the Ordinary Course of Business as of the date
                  thereof based on information available as of such date. It has
                  disclosed to HNC in writing prior to the date hereof the
                  amounts of all past due loans, leases, advances, credit
                  enhancements, other extensions of credit, commitments and
                  interest-bearing assets, and it shall disclose promptly to HNC
                  after the end of each quarter after the date hereof and on the

                  such overdrafts. The OREO and in-substance foreclosures
                  included in any of its non-performing assets are carried net
                  of reserves at the lower of cost or market value based on

         (t)      Material Interests of Certain Persons. Except as noted in
                  Annex 3.1(t), none of its respective officers or directors, or
                  any "associate" (as such term is defined in Rule 12b-2 under
                  the Securities Exchange Act of 1934 (the "Exchange Act")) of
                  any such officer or director, has any material interest in any
                  material contract or property (real or personal), tangible or
                  intangible, used in or pertaining to its business.

         (u)      Insurance. It is presently insured, and has been insured, in
                  the amounts, with the companies and since the periods set
                  forth in Annex 3.1(u). All of the insurance policies and bonds
                  maintained by it are in full force and effect, it is not in
                  default thereunder and all material claims thereunder have
                  been filed in due and timely fashion. In the judgment of its
                  management, such insurance coverage is adequate.

         (v)      Dividends. The only dividends or other distributions which it
                  has made on its capital stock since January 1, 1997 are set
                  forth in Annex 3.1(v).

         (w)      Books and Records. Its books and records have been, and are
                  being, maintained in accordance with applicable legal and
                  accounting requirements and reflect in all material respects
                  the substance of events and transactions that should be
                  included therein.

         (x)      Board Action. Its board of directors (at a meeting duly called
                  and held) has been duly convened and by the requisite vote of
                  the directors (a) determined that the Bank Merger is advisable
                  and in the best interests of it and its shareholders, (b)
                  approved this Agreement, the Bank Merger Agreement, and the
                  transactions contemplated hereby and thereby and (c) directed
                  that the Agreement be submitted for consideration by its
                  shareholders at the CBTC Shareholders' Meeting (as hereafter
                  defined) with the recommendation of the board of directors
                  that the shareholders approve the Bank Merger and the
                  transactions contemplated thereby.

         (y)      Fairness Opinions. Its board of directors has received a
                  written opinion, a copy of which has been furnished to HNC, to
                  the effect that the Exchange Ratio specified in this
                  Agreement, at the time of its execution, is fair to CBTC
                  shareholders from a financial point of view.

         (z)      Fidelity Bonds. Since at least December 31, 1993, CBTC has
                  continuously maintained fidelity bonds insuring it against
                  acts of dishonesty by its employees in such amounts as is
                  customary for a bank of its size. Since December 31, 1993, the
                  aggregate amount of all potential claims under such bonds has
                  not exceeded $50,000 and CBTC is not aware of any facts which
                  would reasonably form the basis of a claim under such bonds.
                  CBTC has no reason to believe that its fidelity coverage will
                  not be renewed by its carrier on substantially the same terms
                  as its existing coverage.

         (aa)     Condition of Tangible Assets. Except as set forth in Annex
                  3.1(aa), all buildings,

                                      A-19

                  structures and improvements on the real property owned or
                  leased by it are in good condition, ordinary wear and tear
                  excepted, and are free from structural defects in all material
                  respects. The equipment, including heating, air conditioning
                  and ventilation equipment owned by it, is in good operating
                  condition, ordinary wear and tear excepted. The operation and
                  use of the property in the business conform in all material
                  respects to all applicable laws, ordinances, regulations,
                  permits, licenses and certificates.

                  Annex 3.1(bb), in the aggregate, the loans by CBTC have been
                  lawfully made, constitute valid debts of the obligors, have
                  been issued, granted or made by CBTC in the Ordinary Course of
                  Business, are subject to the terms of payment as shall have
                  been agreed upon between CBTC and each customer, and CBTC does
                  not know of any applicable set-off or counterclaim which in
                  the aggregate would have a Material Adverse Effect on it. A
                  list of all loans thirty (30) days or more past due as of
                  October 31, 1999, and as of the last day of each month for
                  each of the preceding twelve (12) months thereto has been
                  previously delivered to HNC. No part of the amount collectible
                  under any loan is contingent upon performance by CBTC of any
                  obligation and no agreement for participation, in which CBTC
                  has relinquished or agreed to share control with a
                  participation in management of the facility, or agreement
                  providing for deductions or discounts have been made with
                  respect to any part of such debts. CBTC does not know of any
                  pending, threatened or expected actions in connection with any
                  material loans or commitments presently or previously made by
                  CBTC relating to claims based on theories of "lenders'
                  liability" or any other basis.

                  material respects with the rules and regulations of the FDIC
                  to the extent such rules and regulations are deemed applicable

                  noted or reserved against therein under generally accepted
                  accounting principles or which are in any case or in the
                  aggregate material. Except as described in Annex 3.2(f), since
                  September 30, 1999, HNC has not incurred any such liability
                  other than liabilities of the same nature as those set forth
                  in the HNC Balance Sheet, all of which have been reasonably
                  incurred in the Ordinary Course of Business.

         (g)      Absence of Changes. Since September 30, 1999, there has not
                  been any material and adverse change in the condition
                  (financial or otherwise), assets, liabilities, business,
                  operations or future prospects of HNC or CNB.

         (h)      Litigation. Except as disclosed in Annex 3.2(h): (i) there is
                  no litigation, investigation or proceeding pending, or to the
                  knowledge of HNC threatened, that involves HNC or its
                  properties and that, if determined adversely to HNC, would
                  materially and adversely affect the condition (financial or
                  otherwise), assets, liabilities, business, operations or
                  future prospects of HNC; (ii) there are no outstanding orders,
                  writs, injunctions, decrees, consent agreements, memoranda of


                                      A-26

                  understanding or other directives of any federal, state or
                  local court or governmental authority or of any arbitration
                  tribunal against HNC which materially and adversely affect the
                  condition (financial or otherwise), assets, liabilities,
                  business, operations or future prospects of HNC or restrict in
                  any manner the right of HNC to conduct its business as
                  presently conducted; and (iii) HNC is not aware of any fact or
                  condition presently existing that might give rise to any
                  litigation, investigation or proceeding which, if determined
                  adversely to HNC, would materially and adversely affect the
                  condition (financial or otherwise), assets, liabilities,
                  business, operations or future prospects of HNC. For purposes
                  of this Section 3.2(h), HNC shall be deemed to include CNB.

         (i)      Proxy Statement/Prospectus. At the time the Proxy
                  Statement/Prospectus (as defined in Section 5.1 of this
                  Agreement) is mailed to the shareholders of CBTC and at all
                  times subsequent to such mailing, up to and including the
                  Effective Date, the Proxy Statement/Prospectus (including any
                  pre- and post-effective amendments and supplements thereto),
                  with respect to all information relating to HNC and CNB, HNC
                  Common Stock, and actions taken and statements made by HNC,
                  HNC North and CNB in connection with the transactions
                  contemplated herein (other than information provided by CBTC
                  to HNC and CNB), will: (i) comply in all material respects
                  with applicable provisions of the 1933 Act and the 1934 Act
                  and the pertinent rules and regulations thereunder; and (ii)
                  not contain any statement which, at the time and in light of
                  the circumstances under which it is made, is false or
                  misleading with respect to any material fact, or omits to
                  state any material fact that is necessary to be stated therein
                  in order (A) to make the statements therein not false or
                  misleading, or (B) to correct any statement in an earlier
                  communication with respect to the Proxy Statement/Prospectus
                  which has become false or misleading.

                  date after the date hereof;

         (dd)     not agree to any of the foregoing items (i) through (cc).

SECTION 4.2 Best Efforts.

         CBTC shall cooperate with HNC and CNB and shall use its best efforts to
do or cause to be done all things necessary or appropriate on its part in order
to fulfill the conditions precedent set forth in Article VI of this Agreement
and to consummate this Agreement and the Bank Merger Agreement. In particular,
without limiting the generality of the foregoing sentence, CBTC shall:

         (a)      cooperate with HNC and CNB in the preparation of all required
                  applications for regulatory approval of the transactions
                  contemplated by this Agreement and in the preparation of the
                  Registration Statement (as defined in Section 5.1(b) of this

         (b)      call a special or annual meeting of its shareholders and take,
                  in good faith, all actions which are necessary or appropriate
                  on its part in order to secure the approval and adoption of
                  this Agreement and the Bank Merger Agreement by its
                  shareholders at


                                      A-31
<PAGE>   170

                  that meeting, including recommending the approval of such
                  agreements by the shareholders of CBTC, unless, prior to
                  calling such meeting, it receives a written opinion (subject
                  only to normal and customary qualifications) of outside
                  counsel that the adoption of this Agreement and the Bank
                  Merger Agreement would constitute a breach of the CBTC board
                  of directors' fiduciary duty;

         (c)      cooperate with HNC and CNB in making CBTC's employees
                  reasonably available for training by HNC and CNB prior to the
                  Effective Date, to the extent that such training is deemed
                  reasonably necessary by HNC and CNB to ensure that CBTC's
                  offices will be properly operated as a part of CNB after the
                  Bank Merger;

         (d)      make additions to loan loss reserves and make loan write-offs,
                  write-downs and other adjustments that reasonably should be
                  made by CBTC in accordance with generally accepted accounting

financial reporting purposes. CBTC shall not take (and shall use its best

transactions contemplated by this Agreement in excess of $450,000 unless CBTC
and HNC mutually agree in writing to increase such amount because of unique and

         The respective obligations of the parties to effect the Bank Merger
shall be subject to the satisfaction or waiver prior to the Effective Date of
the following conditions:

         (a)      The Agreement, the Bank Merger Agreement and the transactions
                  contemplated hereby and thereby shall have been approved by
                  the requisite vote of the shareholders of CBTC in accordance
                  with applicable law.

         (b)      All approvals, consents or waivers required by any of the CBTC
                  Regulatory Agencies or the HNC Regulatory Agencies with
                  respect to this Agreement and the Bank Merger Agreement and
                  the transactions contemplated hereby and thereby including,
                  without limitation, the approvals, notices to, consents or
                  waivers of (i) the Board, (ii) the Office of the Comptroller
                  of the Currency ("OCC") and (iii) the Pennsylvania Department
                  of Banking (the CBTC Regulatory Agencies and the HNC
                  Regulatory Agencies, are, collectively the "Regulatory
                  Agencies") shall have been obtained and shall remain in full
                  force and effect, and all applicable statutory waiting periods
                  (including without limitation all applicable statutory waiting

                  Agreement and the Bank Merger Agreement except those
                  approvals, consents or waivers, if any, of which failure to
                  obtain would not, individually or in the aggregate, have a
                  Material Adverse Effect on HNC or CBTC (after giving effect to
                  the transaction contemplated hereby); provided, however, that
                  no such approval shall have imposed any condition or
                  requirement which in the reasonable opinion of the board of
                  directors of HNC or CNB renders consummation of the Bank
                  Merger inadvisable.

         (c)      All other requirements prescribed by law which are necessary
                  to the consummation of the transactions contemplated by this

                  the consummation of the Bank Merger or any other transaction
                  contemplated by this Agreement, and no litigation or
                  proceeding shall be pending against any of the parties herein
                  or any of their subsidiaries brought by any governmental
                  agency seeking to prevent consummation of the transactions
                  contemplated hereby.

         (e)      No statute, rule, regulation, order, injunction or decree
                  shall have been enacted, entered, promulgated or enforced by
                  any governmental authority which prohibits, restricts or makes
                  illegal consummation of the Bank Merger or any other
                  transaction contemplated by this Agreement.

         (f)      The Registration Statement shall have been filed (the date of

                  qualified under the securities or "blue sky" laws of all
                  states in which such action is required for purposes of the
                  initial issuance of such shares and the distribution thereof
                  to the shareholders of CBTC entitled to receive such shares.

         (g)      A ruling from the IRS or an opinion of Shumaker Williams,
                  P.C., counsel to HNC and CNB, or from an accounting firm

                               shares and cash received by CBTC Shareholders who
                               exercise their dissenter's rights, no gain or

                               each instance, the same as the basis of the CBTC
                               Common Stock surrendered in exchange therefor;

                  (v)           The holding period of the HNC Common Stock

<PAGE>   178
                               shareholder receiving HNC Common Stock will
                               include the period during which the CBTC Common

                               share interest of HNC Common Stock, or the tax
                               basis in the shares surrendered, as the case may
                               be, which he would otherwise be entitled to
                               receive and will qualify as capital gain or loss;
                               and

                  (vii)        Subject to any limitations imposed under Sections
                               381 and 382 of the Code, CNB, as the survivor to
                               the Bank Merger, will carry-over and take into
                               account all accounting items and tax attributes

necessary or advisable to obtain such ruling.

                  in this Agreement shall be true and correct in all material

                  on the date when made in the case of any representation or
                  warranty which specifically relates to an earlier date); CBTC
                  shall have performed each of its covenants and agreements

         (b)      Beard & Company, Inc., and if they shall not provide it, such
                  other accounting firm as is acceptable to the parties, shall
                  have furnished to HNC an "agreed upon procedures" letter,
                  dated the Effective Date, in form and substance satisfactory
                  to HNC to the effect that, based upon a procedure performed

                  nothing has come to their attention that would indicate that
                  any material adjustments would be required to the audited
                  financial statements for the period ended December 31, 1999 in
                  order for them to be in conformity with generally accepted
                  accounting principles applied on a consistent basis with that
                  of prior periods.

         (c)      HNC shall have received an opinion or opinions dated as of the

                  had or might reasonably be expected to result in a Material
                  Adverse Effect on CBTC.

         (e)      The Bank Merger shall as of the date of the Closing meet the
                  requirements for pooling-of-interests accounting treatment

         (f)      HNC shall have received from each of the persons identified by
                  CBTC pursuant to Section 4.11 hereof an executed counterpart
                  of an affiliate's agreement in the form contemplated by such
                  Section.

         (g)      Except as otherwise provided in this Agreement, prior to
                  Closing, all issued and outstanding options, warrants or

                  which remain unexercised at the Effective Date.

                  (i) all consents and authorizations of landlords and other
                  persons that are necessary to permit this Agreement and the
                  Bank Merger Agreement to be consummated without violation of
                  any lease or other agreement to which CBTC is a party or by
                  which any of its properties are bound; and (ii) such other
                  certificates and documents as HNC and CNB and their counsel
                  may reasonably request (all of the foregoing certificates and

                  Rights.

                  Agreement and not previously disclosed on Annex 3.1(r) shall
                  have been discovered which would, or which potentially could,
                  materially and adversely affect the condition (financial or
                  otherwise), assets, liabilities, business, operations or
                  future prospects of CBTC; provided, that for purposes of
                  determining the materiality of an undisclosed environmental

                  which, individually or in the aggregate, would have a Material

                  contributions by the Directors, as defined therein, to the
                  Plans.

         (n)      The CBTC board of directors shall have amended each of the
                  Director's Compensation Agreements (the "Compensation
                  Agreements"), attached hereto collectively as Exhibit 3, and
                  each of the Directors, as defined therein, shall have provided
                  his written consent to change the compensation to be paid
                  under the Compensation Agreements, as contemplated by the CBTC

                  representation or warranty which specifically relates to an
                  earlier date); HNC and CNB shall have performed, in all
                  material respects, each of its covenants and agreements
                  contained in this Agreement; and CBTC shall have received

                  aggregate, has had or might reasonably be expected to result
                  in a Material Adverse Effect on HNC or the Material
                  Subsidiaries taken as a whole.

         (d)      The status of all Material pending litigation that might
                  reasonably be expected to result in a Materially Adverse
                  Effect to HNC or the Material Subsidiaries taken as a whole,
                  shall be satisfactory to CBTC.

         (e)      The shares of HNC Common Stock to be issued in the Bank Merger
                  shall have been authorized to be listed for quotation on the

                  material breach by HNC of any representation, warranty,
                  covenant or agreement contained herein and such breach is not
                  cured or not curable within thirty (30) days after written
                  notice of such breach is given to HNC by CBTC or (ii) by

                  September 30, 2000.

                  that the Bank Merger is not consummated by September 30, 2000,
                  unless the failure to so consummate by such time is due to the
                  material breach of any representation, warranty or covenant
                  contained in this Agreement by the party seeking to terminate,
                  provided, however, that such date may be extended by the
                  written agreement of the parties hereto.

                  upon consummation of such offer, such person would own,
                  control or have the right to acquire 20 percent or more of
                  CBTC Common Stock.

SECTION 7.2 Effect of Termination.

         In the event of the termination of this Agreement and the Bank Merger

abandonment.

SECTION 7.3 Expenses.

         Any termination of this Agreement pursuant to Sections 7.1(a) or 7.l(d)
hereof shall be without cost, expense or liability on the part of any party to
the others. Any termination of this Agreement pursuant to Section 7.1(b) or
7.1(c) hereof shall also be without cost, liability or expense on the part of

out-of pocket costs and expenses, including without limitation, reasonable
legal, accounting and investment banking fees and expenses, incurred by such
other party in connection with their entering into this Agreement and their
carrying out of any and all acts contemplated hereunder ("Expenses").

         So long as HNC shall not have breached its obligations hereunder, if
this Agreement is terminated by HNC pursuant to Section 7.1 (c) hereof, CBTC
shall promptly, but in no event later than four (4) business days after such
termination, pay HNC a fee of $350,000, which amount shall be payable by wire

pay the amount due pursuant to this Section 7.3, and, in order to obtain such
payment, HNC commences a suit which results in a judgment against CBTC for all
or a substantial portion of the fee set forth in this Section 7.3, CBTC shall
pay to HNC all costs and expenses (including reasonable attorneys' fees)
incurred by HNC in connection with such suit.

                  Effective Date, any persons who are officers and employees of
                  CBTC immediately before the Effective Date. It shall be a
                  condition to employment by HNC or any of its affiliates that

                  and conditions of the Plans, former CBTC employees who are
                  employed by the respective HNC Affiliate shall receive service

                  respective HNC Affiliate's benefit plans.

         (c)      To the extent permitted by the terms of the applicable plan,
                  HNC will, or will cause the respective HNC Affiliate to, waive
                  all limitations as to pre-existing condition requirements,
                  exclusions and any waiting periods with respect to
                  participation and coverage requirements for health, welfare,
                  life, disability and other benefits for employees offered
                  employment with an HNC Affiliate so that such employees shall
                  be eligible to participate in HNC's health, welfare and
                  benefit plans on the Effective Date.

         (d)      As provided herein, HNC will provide, after the Bank Merger,
                  severance payments to employees of CBTC (other than employees
                  whose severance benefits are provided for in written
                  employment agreements) whose employment is terminated (other
                  than for cause) or who are laid off from their employment on

                  months following the Effective Date and who sign a release of
                  any and all claims the employee may have against CBTC, HNC or
                  an HNC Affiliate. HNC, CNB and CBTC shall consult and mutually
                  agree upon the individual amounts to be received by former
                  CBTC employees who are eligible for severance payments.
                  Factors to be considered in the determination of individual
                  severance payments to former CBTC employees include, among
                  others: years of service, title and responsibilities.

         (e)      HNC and CNB reserve any and all rights they may have regarding
                  modification, amendment or termination of CBTC's present
                  pension and profit sharing plans.

                         DEFERRED COMPENSATION AGREEMENT

         THIS AGREEMENT made this 28th day of August, 1987 by and between
CITIZENS BANK AND TRUST COMPANY, 372 Delaware Avenue, Palmerton, Pennsylvania
(hereinafter called "Bank") and THOMAS K. THOMAS, 145 Delaware Avenue,
Palmerton, Pennsylvania 18071 (hereinafter called "Director").
         WHEREAS, the Bank recognizes that the competent and faithful efforts of
Director on behalf of the Bank have contributed significantly to the success and
growth of the Bank; and
         WHEREAS, the Bank values the efforts, abilities and accomplishments of
the Director and recognizes that his services are vital to its continued growth
and profits in the future; and
         WHEREAS, the Bank desires to compensate the Director and retain his
services for twelve years, and the Director has agreed to defer from his
earnings from the Bank Four Thousand Dollars ($4,000.00) per year for twelve
years.
         NOW, THEREFORE, in consideration of the covenants hereinafter contained
and intending by this Agreement to be legally bound, Bank and Director agree as
follows:

         1.       The Bank agrees to pay Director the total sum One Hundred
                  Ninety-three Thousand Five hundred Ninety-four Dollars
                  ($193,594) payable in monthly installments of One Thousand Six
                  Hundred Thirteen Dollars and Twenty-eight Cents ($1,613.28)
                  for 120 consecutive months, commencing on the first day of the
                  month following Director's 65th birthday. Payments to the
                  Director will terminate when the 120 payments have been made
                  or at the time of the Director's death, whichever occurs
                  first.

         2.       In the event Director should die before attaining age 65, the
                  Bank agrees to pay the Director's beneficiary designated in
                  writing to the Bank, the sum of One Thousand Six Hundred
                  Seventy-nine Dollars and Thirty-three Cents ($1,679.33) per
                  month for 120 consecutive months. Payments will begin on the
                  first day of the month


                                     A-2-2
<PAGE>   202

                  following Director's death.

         3.       If the Director dies after age 65, but prior to receiving the
                  full 120 monthly installments, the remaining monthly
                  installments will be paid to the Director's designated
                  beneficiary. The beneficiary shall receive all remaining
                  monthly installments which the Director would have received
                  until the total sum of One Hundred Ninety-three Thousand Five
                  Hundred Ninety-four Dollars ($193,594) set forth in Paragraph
                  1 is paid. If the Director fails to designate a beneficiary in
                  writing to the Bank, the balance of the monthly installments
                  remaining at the time of his death shall be paid to the
                  personal representative of the estate of the Director.

         4.       If the Director, for any reason other than death, fails to
                  serve twelve consecutive years as a Director, he will receive
                  monthly compensation beginning at age 65 on the basis that the
                  sum of full months served bears to the required number of 144
                  months times the compensation stated in Paragraph 1.

         5.       No payments will be made to the Director's beneficiary or to
                  his estate in the event of death by suicide during the first
                  three years of this Agreement.

         6.       This Agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's shareholders to replace the
                  Director or the right of the Director to terminate his
                  service.

         7.       The service of the Director shall not be deemed to have been
                  terminated or interrupted due to his absence from active
                  service on account of illness, disability, during any
                  authorized vacation or during temporary leaves of absence
                  granted by the Bank for reasons of professional advancement,
                  education, health or government service, or during military
                  leave for any period if the Director is elected to serve on


                                     A-2-3
<PAGE>   203

                  the Board following such interruption.

         8.       The Director agrees that all rights to compensation following
                  age 65 shall be forfeited hy him if he engages in competition
                  with the Bank, without the prior written consent of the Bank,
                  within a radius of 50 miles of the main office of the Bank for
                  a period of ten years, coinciding with the number of years
                  that the Director shall receive such compensation.

         9.       None of the rights to compensation under this Agreement are
                  assignable by the Director or any beneficiary or designee of
                  the Director and any attempt to anticipate, sell, transfer,
                  assign, pledge, encumber or change Director's rights to
                  receive compensation, shall be void.

         10.      The rights granted to the Director or any designee or
                  beneficiary under this Agreement shall be solely those of any
                  unsecured creditor of the Bank.

         11.      If the Bank shall acquire an insurance policy or any other
                  asset in connection with the liabilities assumed by it
                  hereunder, it is expressly understood and agreed that neither
                  Director nor any beneficiary of Director shall have any right
                  with respect to, or claim against, such policy or other asset
                  except as expressly provided by the terms of such policy or in
                  the title to such other asset. Such policy or asset shall not
                  be deemed to be held under trust for the benefit of Director
                  or hid beneficiary or to be held in any way as collateral
                  security for the fulfilling of the obligations of the Bank
                  under this Agreement except as may be expressly provided by
                  the terms of such policy or other asset. It shall be, and
                  remain, a general, unpledged, unrestricted asset of the Bank.

         12.      This Agreement shall be construed under and governed by the
                  laws of the State of Pennsylvania.

         WHEREAS, the Employee has agreed to defer from her earnings from the
Bank Five Hundred ($500.00) per year until she retires at age 65.

         NOW, THEREFORE, in consideration of the covenants hereinafter contained
and intending by this agreement to be legally bound, Bank and Employee agree as
follows:

         1.       The Bank agrees to pay Employee that total sum of Two Hundred
                  Fifty-two Thousand One Hundred Seventeen Dollars and No Cents
                  ($252,117.00) payable in monthly installments of Two Thousand
                  One Hundred Dollars and Ninety-seven Cents ($2,0100.97) for
                  120 consecutive months, commencing on the first day of the
                  month following the Employee's 65th birthday. Payments to the
                  Employee will terminate when the 120 payment have been made or
                  at the time of the Employee's death, whichever comes first.

         2.       In the event Employee should die before attaining age 65, the
                  Bank agrees to pay to Employee's Beneficiary(ies) designated
                  in writing to the Bank, the sum of Eight hundred Three Dollars
                  and Seventy-five Cents ($803.75) for 120 consecutive months.
                  Payments will begin on the first day of the month following
                  Employee's death.

         3.       If the Employee dies after age 65, but prior to receiving the
                  full 120 monthly installments, the remaining monthly
                  installments will be paid to the Employee's designated
                  beneficiary(ies). The beneficiary(ies) shall receive all
                  remaining monthly installments which the Employee would have
                  received until the total sum of Two Hundred Fifty-two Thousand
                  One Hundred Seventeen Dollars and No cents ($252,117.00) set
                  forth in Paragraph 1 is paid. If Employee fails to designate a
                  beneficiary in writing to the Bank, the balance of the monthly
                  installments remaining at the time of her death shall be paid
                  to the personal representative of the estate of the Employee.

         4.       If the Employee, for any reason other than death, fails to
                  remain employed by Bank until her retirement at age 65, she
                  will receive monthly compensation beginning at age 65 on the
                  basis that the sum of full months served from the date of this
                  contract bears to the required number of months from the date
                  of this contract to age 65 times that compensation stated in
                  Paragraph 1.

         5.       No payments will be made to the Employee's beneficiary(ies) or
                  to her estate in the event of death by suicide during the
                  first three years of this Agreement.

         6.       This agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's directors to replace the
                  Employee or the rights of the employee to terminate her
                  service by



                                     A-2-8
<PAGE>   208

                  resignation.

         7.       The service of the employee shall not be deemed to have been
                  terminated or interrupted due to her absence from active
                  service on account of illness, disability, during any
                  authorized vacation or during temporary leaves of absence
                  granted by the Bank for reasons of professional advancement,
                  education, health or government service, or during military
                  leave for any period if the Employee returns to her employment
                  following such interruption.

         8.       The Employee agrees that all rights to compensation following
                  age 65 shall be forfeited by her if she (at that time) engages
                  in )Bank) competition with the Bank, without prior written
                  consent of the Bank, within a radius of 20 miles of the main
                  office of the Bank for a period of 10 years, coinciding with
                  the number of years that the Employee shall receive such
                  compensation.

         9.       None of the rights to compensation under this Agreement are
                  assignable by the Employee or any beneficiary or designee of
                  the Employee and any attempt to anticipate, sell, transfer,
                  assign, pledge, encumber or change Employee's right to receive
                  compensation, shall be void.

         10.      The rights granted to the Employee or any designee or
                  beneficiary under this Agreement shall be solely those of an
                  unsecured creditor of the Bank.

         11.      If the Bank shall acquire an insurance policy or any other
                  asset in connection with the liabilities assumed by it
                  hereunder, it is expressly understood and agreed that neither
                  Employee nor any beneficiary of Employee shall have any right
                  with respect to, or claim against, such policy or other asset
                  except as expressly provided by the terms of such policy or in
                  the title to such other asset. Such policy or asset shall not
                  be deemed to be held under any trust for the benefit of

                  security for the fulfilling of the obligations of the Bank

                  the terms of such policy or other asset. it shall be, and
                  remain, a general, unpledged, unrestricted asset of the Bank.

         12.      This Agreement shall be construed under the governed by the
                  laws of the State of Pennsylvania.

         13.      this Agreement shall be binding upon the parties hereto and
                  their respective heirs, administrators, successors and
                  assigns.

                        DEFERRED COMPENSATION AGREEMENT



         THIS AGREEMENT made this 28th day of October, 1987 by and between
CITIZENS BANK AND TRUST COMPANY, 372 Delaware Avenue, Palmerton, Pennsylvania
(hereinafter called "Bank") and RONALD J. STEBER, of R.D. #6, Box 402,
Lehighton, Pennsylvania 18235 (hereinafter called "Officer").

         WHEREAS, the Bank recognizes that the competent and faithful efforts of
Officer on behalf of the Bank have contributed significantly to the success and
growth of the Bank; and

         WHEREAS, the Bank values the efforts, abilities and accomplishments of
the Officer and recognizes that his services are vital to its continued growth
and profits in the future; and

         WHEREAS, the Bank desires to compensate the Officer and retain his
services for nine years, and the Officer has agreed to defer from his earnings
from the Bank One Thousand Two Hundred Dollars ($1,200.00) per year for nine (9)
years.

         NOW, THEREFORE, in consideration of the covenants hereinafter contained
and intending by this Agreement to be legally bound, Bank and Officer agree as
follows:

1.                The Bank agrees to pay Officer the total sum of Ninety-one
                  Thousand Twenty-two Dollars ($91,022) payable in monthly
                  installments of Seven Hundred Fifty-eight Dollars and Fifty
                  Cents ($758.50) for 120 consecutive months, commencing on the
                  first day of the month following Officer's 65th birthday.
                  Payments to the Officer will terminate when the 120 payments
                  have been made or at the time of the Officer's death,
                  whichever occurs first.

2.                In the event Officer should die before attaining age 65, the
                  Bank agrees to pay to Officer's beneficiary designated in
                  writing to the Bank, the sum of Seven Hundred Seven Dollars
                  and Seventeen Cents ($707.17) per month for 120 consecutive

                                     A-2-12

                  months. Payments will begin on the first day of the month
                  following Officer's death.

3.                If the Officer dies after age 65, but prior to receiving the
                  full 120 monthly installments, the remaining monthly
                  installments will be paid to the Officer's designated
                  beneficiary. The beneficiary shall receive all remaining
                  monthly installments which the Officer would have received
                  until the total sum of Ninety-one Thousand Twenty-two Dollars
                  ($91,022) set forth in Paragraph 1 is paid. If the Officer
                  fails to designate a beneficiary in writing to the Bank, the
                  balance of the monthly installments remaining at the time of
                  his death shall be paid to the personal representative of the
                  estate of the Officer.

4.                If the Officer, for any reason other than death, fails to
                  serve nine consecutive years as a Officer, he will receive
                  monthly compensation beginning at age 65 on the basis that the
                  sum of full months served bears to the required number of 108
                  months times the compensation stated in Paragraph 1.

5.                No payments will be made to the Officer's beneficiary or to
                  his estate in the event of death by suicide during the first
                  three years of this Agreement.

6.                This Agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's management to replace the
                  Officer or the right of the Officer to terminate his service.

7.                The service of the Officer shall not be deemed to have been
                  terminated or interrupted due to his absence from active
                  service on account of illness, disability, during any
                  authorized vacation or during temporary leaves of absence
                  granted by the Bank for reasons of professional advancement,
                  education, health or government service, or during military
                  Bank following such interruption.

<PAGE>   213


8.                The Officer agrees that all rights to compensation following
                  age 65 shall be forfeited by him if he engages in competition
                  with the Bank, without the prior written consent of the Bank,
                  within a radius of 50 miles of the main office of the Bank for
                  a period of ten years, coinciding with the number of years
                  that the Officer shall receive such compensation.

9.                None of the rights to compensation under this Agreement are
                  assignable by the Officer or any beneficiary or designee of
                  the Officer and any attempt to anticipate, sell, transfer,
                  assign, pledge, encumber or change Officer's right to receive
                  compensation shall be void.

10.               The rights granted to the Officer or any designee or
                  beneficiary under this Agreement shall be solely those of an
                  unsecured creditor of the Bank.

11.               If the Bank shall acquire an insurance policy or any other
                  asset in connection with the liabilities assumed by it
                  hereunder, it is expressly understood and agreed that neither
                  Officer nor any beneficiary or Officer shall have any right
                  with respect to, or claim against, such policy or other asset
                  except as expressly provided by the terms of such policy or in
                  the title to such other asset. Such policy shall not be deemed
                  to be held under any trust for the benefit of Officer or his
                  beneficiary or to be held in any way as collateral security
                  for the fulfilling of the obligations of the Bank under this
                  Agreement except as may be expressly provided by the terms of
                  such policy or other asset. It shall be, and remain, a
                  general, unpledged, unrestricted asset of the Bank.

                         DEFERRED COMPENSATION AGREEMENT

         THIS AGREEMENT made this 15th day of August, 1987, by and between
CITIZENS BANK AND TRUST COMPANY, 372 Delaware Avenue, Palmerton, Pennsylvania
(hereinafter called "Bank") and JAMES A. WIMMER, 1412 Hampton Road, Allentown,
Pennsylvania 18104 (hereinafter called "Director").

         WHEREAS, the Bank recognizes that the competent and faithful efforts of
Director on behalf of the Bank have contributed significantly to the success and
growth of the Bank; and

         WHEREAS, the Bank values the efforts, abilities and accomplishments of
the Director and recognizes that his services are vital to its continued growth
and profits in the future; and

         WHEREAS, the Bank desires to compensate the Director and retain his
services for nine years, and the Director has agreed to defer from his earnings
from the Bank Six Thousand Dollars ($6,000.00) per year for nine (9) years.

         NOW, THEREFORE, in consideration of the covenants hereinafter contained
and intending by this Agreement to be legally bound, Bank and Director agree as
follows:

         1.       The Bank agrees to pay Director the total sum of Four Hundred
                  Thirty-eight Thousand Seven Hundred Eighty-nine Dollars
                  ($438,789), payable in monthly installments of Thirty-six
                  Hundred Fifty-six Dollars and Fifty-eight Cents ($3,656.58)
                  for 120 consecutive months, commencing on the first day of the
                  month following Director's 65th birthday. Payments to the
                  Director will terminate when the 120 payments have been made
                  or at the time of the Director's death, whichever occurs
                  first.

         2.       In the event Director should die before attaining age 65, the
                  Bank agrees to pay to Director's beneficiary designated in

                  Four Hundred Forty-eight Dollars and Seventeen Cents
                  ($3,448.17) per month for 120 consecutive months. Payments
                  will begin on the first day of the month following Director's
                  death.

         3.       If the Director dies after age 65, but prior to receiving the
                  full 120 monthly installments, the remaining monthly
                  installments will be paid to the Director's designated
                  beneficiary. The beneficiary shall receive all remaining
                  monthly installments which the Director would have received
                  until the total sum of Four Hundred Thirty-eight Thousand
                  Seven Hundred Eighty-nine Dollars ($438,789) set forth in
                  Paragraph 1 is paid. If the Director fails to designate a
                  beneficiary in writing to the Bank, the balance of the monthly
                  installments remaining at the time of his death shall be paid
                  to the personal representative of the estate of the Director.

         4.       If the Director, for any reason other than death, fails to
                  serve twelve consecutive years as a Director, he will receive
                  monthly compensation beginning at age 65 on the basis that the
                  sum of full months served bears to the required number of 108
                  months times the compensation stated in Paragraph 1.

         5.       No payments will be made to the Director's beneficiary or to
                  his estate in the event of death by suicide during the first
                  three years of this Agreement.

         6.       This Agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's shareholders to replace the
                  Director of the right of the Director to terminate his
                  service.

         7.       The service of the Director shall not be deemed to have been
                  terminated or interrupted due to his absence from active
                  service on account of illness, disability, during any
                  authorized vacation or during temporary leaves of absence
                  granted by

                  the Bank for reasons of professional advancement, education,
                  health or government service, or during military leave for any
                  period if the Director is elected to serve on the Board
                  following such interruption.

         8.       The Director agrees that all rights to compensation following
                  age 65 shall be forfeited by him if he engages in competition
                  with the Bank, without the prior written consent of the Bank,
                  within a radius of 50 miles of the main office of the Bank for
                  a period of ten years, coinciding with the number of years
                  that the Director shall receive such compensation.

         9.       None of the rights to compensation under this Agreement are
                  assignable by the Director or any beneficiary or designee of
                  the Director and any attempt to anticipate, sell, transfer,
                  assign, pledge, encumber or change Director's right to receive
                  compensation, shall be void.

         10.      The rights granted to the Director or any designee or
                  beneficiary under this Agreement shall be solely those of an
                  unsecured creditor of the Bank.

         11.      If the Bank shall acquire an insurance policy or any other
                  asset in connection with the liabilities assumed by it
                  hereunder, it is expressly understood and agreed that neither
                  Director nor any beneficiary of Director shall have any right
                  with respect to, or claim against, such policy or other asset
                  except as expressly provided by the terms of such policy or in
                  the title to such other asset. Such policy or asset shall not
                  be deemed to be held under any trust for the benefit of
                  Director or his beneficiary or to be held in any way as
                  collateral security for the fulfilling of the obligations of
                  the Bank under this Agreement except as may be expressly
                  provided by the terms of such policy or other asset. It shall
                  be, and remain, a general, unpledged unrestricted asset of the
                  Bank.

(hereinafter called "Bank") and TERRY D. ECKERT, OF Palmerton, Pennsylvania
(hereinafter called "Director").

         WHEREAS, the Bank recognizes that the competent and faithful efforts of

<PAGE>   222
         2.       In the event Director should die before attaining age 65, the
                  Bank agrees to pay to Director's beneficiary(ies) designated
                  in writing to the Bank, the sum of Two Thousand Seven Dollars

         3.       If the Director dies after age 65, but prior to receiving the

                  beneficiary(ies). The beneficiary(ies) shall receive all
                  remaining monthly installments which the Director would have

         4.       If the Director, for any reason other than death, fails to
                  remain employed by Bank for 14 consecutive years he will
                  receive monthly compensation beginning at age 65 on the basis
                  that the sum of full months served from the date of this
                  contract to age 65 times that compensation stated in Paragraph
                  1.

         5.       No payments will be made to the Director's beneficiary(ies) or
                  to his estate in the event of death by suicide during the
                  first three years of this Agreement.

         6.       This agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's shareholders to replace the
                  Director or the right of the Director to terminate his service
                  by resignation.

                  reasons of professional advancement, education, health or
                  government service, or during military leave for any period if
                  the Director returns to his employment following such
                  interruption.

         8.       The Director agrees that all rights to compensation following
                  age 65 shall be forfeited by him if he engage in competition

                  within a radius of 50 miles of the main office of the Bank for
                  a period of 10 years coinciding with the number of years that
                  the Director shall receive such compensation.

         9.       None of the rights to compensation under this Agreement are
                  assignable by the Director or any beneficiary or designee of
                  the Director and any attempt to anticipate, sell, transfer,
                  assign, pledge, encumber or change Director's right to receive

                  unsecured creditor of the Bank.

         11.      If the Bank shall acquire an insurance policy or an other
                  asset in connection with the liabilities assumed by it
                  hereunder, it is expressly understood and agreed that neither
                  Director nor any beneficiary or Director shall have any right
                  with respect to, or claim against, such policy or other asset
                  except as expressly provided by the terms of such policy or in
                  the title to such other asset. Such policy or asset shall not
                  be deemed to be held under any trust for the benefit of
                  Director or his beneficiary(ies) or to be held in any way as
                  collateral security for the fulfilling of the obligations of
                  the Bank under this Agreement except as may be expressly
                  provided by the terms of

         THIS AGREEMENT made this 2nd day of October, 1987 by and between
CITIZENS BANK AND TRUST COMPANY, 372 Delaware Avenue, Palmerton, Pennsylvania
(hereinafter called "Bank") and ROBERT ADAMS, of 450 Princeton Avenue,
Palmerton, Pennsylvania 18071 (hereinafter called "Officer").

         WHEREAS, the Bank recognizes that the competent and faithful efforts of
Officer on behalf of the Bank have contributed significantly to the success and
growth of the Bank; and

         WHEREAS, the Bank values the efforts, abilities and accomplishments of
the Officer and recognizes that his services are vital to its continued growth
and profits in the future; and

         WHEREAS, the Bank desires to compensate the Officer and retain his
services for two years, and the Officer has agreed to defer from his earnings
from the Bank Nine Thousand Three Hundred Thirty-nine Dollars ($9,339.00) per
year for two (2) years.

         NOW, THEREFORE, in consideration of the covenants hereinafter contained
and intending by this Agreement to be legally bound, Bank and Officer agree as
follows:

         1.       The Bank agrees to pay Officer the total sum of Seventy-eight
                  Thousand Seven Hundred eighty-five Dollars ($78,785) payable
                  in monthly installments of Six Hundred Fifty-six Dollars and
                  Fifty Cents ($656.50) for 120 consecutive months, commencing
                  on the first day of the month following Officer's 65th
                  birthday. Payments to the Officer will terminate when the 120
                  payments have been made or at the time of the Officer's death,
                  whichever occurs first.

         2.       In the event Officer should die before attaining age 65, the
                  Bank agrees to pay to Officer's beneficiary designated in
                  writing to the Bank, the sum of Eight Hundred Seventeen
                  Dollars and Ninety-two Cents ($817.92) per month for 120
                  consecutive

                                     A-2-27
<PAGE>   227
                  months. Payments will begin on the first day of the month
                  following Officer's death.

         3.       If the Officer dies after age 65, but prior to receiving the
                  full 120 monthly installments, the remaining monthly
                  installments will be paid to the Officer's designed
                  beneficiary. The beneficiary shall receive all remaining
                  monthly installments which the Officer would have received
                  until the total sum of Seventy-eight Thousand Seven Hundred
                  Eighty-five Dollars ($78,785) set forth in Paragraph 1 is
                  paid. If the Officer fails to designate a beneficiary in
                  writing to the Bank, the balance of the monthly installments
                  remaining at the time of his death shall be paid to the
                  personal representative of the estate of the Officer.

         4.       If the Officer, for any reason other than death, fails to
                  serve two consecutive years as a Officer, he will receive
                  monthly compensation beginning at age 65 on the basis that the
                  sum of full months served bears to the required number of 24
                  months times the compensation stated in Paragraph 1.

         5.       No payments will be made to the Officer's beneficiary or to
                  his estate in the event of death by suicide during the first
                  three years of this Agreement.

         6.       This Agreement does not constitute a contract of employment
                  between the parties, nor shall any provision of this Agreement
                  restrict the right of the Bank's management to replace the
                  Officer or the right of the Officer to terminate his service.

         7.       The service of the Officer shall not be deemed to have been
                  terminated or interrupted due to his absence from active
                  service on account of illness, disability, during any
                  authorized vacation or during temporary leaves of absence
                  granted by the Bank for reasons of professional advancement,
                  education, health or government service, or during military
                  leave for any period if the Officer continues to be

<PAGE>   228
                  employed by Bank following such interruption.

         This Agreement is entered into this first day of April, 1983, between
CITIZENS BANK & TRUST COMPANY, 372 Delaware Avenue, Palmerton, Pennsylvania
18071 (Herein referred to as the "Bank") and JAMES A. WIMMER, 1412 Hampton Road,
Allentown, Pennsylvania 18104 (Herein referred to as the "Director").

                               W I T N E S S E T H

         WHEREAS, the Bank recognizes that the competent and faithful efforts of
Director on behalf of the Bank have contributed significantly to the success and
growth of the Bank; and

         WHEREAS, the Bank values the efforts, abilities and accomplishments of
the Director and recognizes that his services are vital to its continued growth
and profits in the future; and

         WHEREAS, the Bank desires to compensate the Director and retain his
services for four years, if elected, to serve on the Board of Directors. Such
compensation is set forth below; and

         WHEREAS, the Director, in consideration of the foregoing, agrees to
continue to serve as a Director, if elected,

         NOW, THEREFORE, it is mutually agreed as follows:

         1. Compensation. The Bank agrees to pay Director the total sum of
$890,110 payable in monthly installments of $7,417.58 for 120 consecutive
months, commencing on the first day of the month following Director's 65th
birthday. Payments to the Director will terminate when the 120 payments have
been made or at the time of the Director's death, whichever occurs first.

         2. Death of Director Before Age 65. In the event Director should die
before reaching age 65, the Bank agrees to pay to Director's beneficiary
designated in writing to the Bank, the sum of $3,017.75 per month for 120
consecutive months. Payments will begin on the first day of the month following
Director's death.

         3. Indexing of Deferred Income Payments. The deferred income payments
stated in Paragraph "1" and Paragraph "2" of this agreement will be made
provided the monthly average of the Moody's 20 Year Corporate Bond Average is
between 11% and 13% from (date of agreement) until payments are commenced. If
the monthly average of the Moody 20 Year Corporate Bond Average is between 11%
and 13% for that period, the payments may be indexed by the Bank in accordance
with the actual average of the Moody 20 Year Corporate Bond Average.

                                      A-3-3
<PAGE>   235
         4. Death of Director After Age 65. If the Director dies after age 65
prior to receiving the full 120 monthly installments, the remaining monthly
installments will be paid to the Director's designated beneficiary (ies). The
beneficiary (ies) shall receive all remaining monthly installments which the
Director would have received until the total sum of $890,110 set forth in
paragraph "1" is paid. If the Director fails to designate a beneficiary in
writing to the Bank, the balance of monthly installments remaining at the time
of his death shall be paid to the legal representative of the estate of the
Director.

         5. Termination of Service as A Director. If the Director, for any
reason other than death, fails to serve four consecutive years as a Director, he
will receive monthly compensation beginning at age 65 on the basis that the
number of full months served bears to the required number of 48 months times the
compensation stated in paragraph "1". For example, if the Director serves only
24 months, he will be entitled to 24/48 or 50% of the compensation stated in
paragraph "1".

         6. Suicide. No payments will be made to the Director's beneficiary
(ies) or to his estate in the event of death by suicide during the first three
years of this agreement.

         7. Status of Agreement. This agreement does not constitute a contract
of employment between the parties, nor shall any provision of this agreement
restrict the right of the Bank's Shareholders to replace the Director or the
right of the Director to terminate his service.

         8. Binding Effect. This agreement shall be binding upon the parties
hereto and upon the successors and assigns of the Bank, and upon the heirs and
legal representatives of the Director.

         9. Interruption of Service. The service of the Director shall not be
deemed to have been terminated or interrupted due to his absence from active
service on account of illness, disability, during any authorized vacation or
during temporary leaves of absence granted by the Bank for reasons of
professional advancement, education, health or government service, or during
military leave for any period if the Director is elected to serve on the Board
following such interruption.

         10. Forfeiture of Compensation by Competition. The Director agrees that
all rights to compensation following age 65 shall be forfeited by him if he
engages in competition with the Bank, without the prior written consent of the
Bank, within a radius of 50 miles of the main office of the Bank for a period of
ten years, coinciding with the number of years that the Director shall receive
such compensation.

         11. Assignment of Rights. None of the rights to compensation under this
Agreement are assignable by the Director or any beneficiary or designee of the
Director and any attempt to

                                      A-3-4
<PAGE>   236
anticipate, sell, transfer, assign, pledge, encumber or change Director's right
to receive compensation, shall be void.

         12. Status of Director's Rights. The rights granted to the Director or
any designee or beneficiary under this Agreement shall be solely those of an
unsecured creditor of the Bank.

         13. Amendments. This Agreement may be amended only by a written
Agreement signed by the parties.

         14. If the Bank shall acquire an insurance policy or any other asset in
connection with the liabilities assumed by it hereunder, is expressly understood
and agreed that neither Director nor any beneficiary of Director shall have any
right with respect to, or claim against, such policy or other asset except as
expressly provided by the terms of such policy or in the title to such other
asset. Such policy or asset shall not be deemed to be held under any trust for
the benefit of Director or his beneficiaries or to be held in any way as
collateral security for the fulfilling of the obligations of the Bank under this
Agreement except as may be expressly provided by the terms of such policy or
other asset. It shall be, and remain, a general, unpledged, unrestricted asset
of the Bank.

         15. This agreement shall be construed under and governed by the laws of
the State of Pennsylvania.

         16. Interpretation. Wherever appropriate in this Agreement, words used
in the singular shall include the plural and the masculine shall include the
feminine gender.

         IN WITNESS HEREOF, the parties have signed this Agreement the day and
year above written.

         WHEREAS, the Director, in consideration of the foregoing, agrees to
continue to serve as a Director, if elected,

         NOW, THEREFORE, it is mutually agreed as follows:

         1. Compensation. The Bank agrees to pay Director the total sum of
$1,407,720 payable in monthly installments of $11,731 for 120 consecutive
months, commencing on the first day of the month following Director's 65th
birthday. Payments to the Director will terminate when the 120 payments have
been made or at the time of the Director's death, whichever occurs first.

         2. Death of Director Before Age 65. In the event Director should die
before reaching age 65, the Bank agrees to pay to Director's beneficiary
designated in writing to the Bank, the sum of $3,232.42 per month for 120
consecutive months. Payments will begin on the first day of the month following
Director's death.

         3. Indexing of Deferred Income Payments. The deferred income payments
stated in Paragraph "1" and Paragraph "2" of this agreement will be made
provided the monthly average of the Moody's 20 Year Corporate Bond Average is
between 11% and 13% from (date of agreement) until payments are commenced. If
the monthly average of the Moody 20 Year Corporate Bond Average is between 11%
and 13% for that period, the payments may be indexed by the Bank in accordance
with the actual average of the Moody 20 Year Corporate Bond Average.

                                     A-3-11
<PAGE>   243
         4. Death of Director After Age 65. If the Director dies after age 65
prior to receiving the full 120 monthly installments, the remaining monthly
installments will be paid to the Director's designated beneficiary (ies). The
beneficiary (ies) shall receive all remaining monthly installments which the
Director would have received until the total sum of $1,407,720 set forth in
paragraph "1" is paid. If the Director fails to designate a beneficiary in
writing to the Bank, the balance of monthly installments remaining at the time
of his death shall be paid to the legal representative of the estate of the
Director.

         5. Termination of Service as A Director. If the Director, for any
reason other than death, fails to serve four consecutive years as a Director, he
will receive monthly compensation beginning at age 65 on the basis that the
number of full months served bears to the required number of 48 months times the
compensation stated in paragraph "1". For example, if the Director serves only
24 months, he will be entitled to 24/48 or 50% of the compensation stated in
paragraph "1".

         6. Suicide. No payments will be made to the Director's beneficiary
(ies) or to his estate in the event of death by suicide during the first three
years of this agreement.

         7. Status of Agreement. This agreement does not constitute a contract
of employment between the parties, nor shall any provision of this agreement
restrict the right of the Bank's Shareholders to replace the Director or the
right of the Director to terminate his service.

         8. Binding Effect. This agreement shall be binding upon the parties
hereto and upon the successors and assigns of the Bank, and upon the heirs and
legal representatives of the Director.

         9. Interruption of Service. The service of the Director shall not be
deemed to have been terminated or interrupted due to his absence from active
service on account of illness, disability, during any authorized vacation or
during temporary leaves of absence granted by the Bank for reasons of
professional advancement, education, health or government service, or during
military leave for any period if the Director is elected to serve on the Board
following such interruption.

         10. Forfeiture of Compensation by Competition. The Director agrees that
all rights to compensation following age 65 shall be forfeited by him if he
engages in competition with the Bank, without the prior written consent of the
Bank, within a radius of 50 miles of the main office of the Bank for a period of
ten years, coinciding with the number of years that the Director shall receive
such compensation.

         11. Assignment of Rights. None of the rights to compensation under this
Agreement are assignable by the Director or any beneficiary or designee of the
Director and any attempt to

                                     A-3-12
<PAGE>   244
anticipate, sell, transfer, assign, pledge, encumber or change Director's right
to receive compensation, shall be void.

         12. Status of Director's Rights. The rights granted to the Director or
any designee or beneficiary under this Agreement shall be solely those of an
unsecured creditor of the Bank.

         13. Amendments. This Agreement may be amended only by a written
Agreement signed by the parties.

         14. If the Bank shall acquire an insurance policy or any other asset in
connection with the liabilities assumed by it hereunder, is expressly understood
and agreed that neither Director nor any beneficiary of Director shall have any
right with respect to, or claim against, such policy or other asset except as
expressly provided by the terms of such policy or in the title to such other
asset. Such policy or asset shall not be deemed to be held under any trust for
the benefit of Director or his beneficiaries or to be held in any way as
collateral security for the fulfilling of the obligations of the Bank under this
Agreement except as may be expressly provided by the terms of such policy or
other asset. It shall be, and remain, a general, unpledged, unrestricted asset
of the Bank.

         15. This agreement shall be construed under and governed by the laws of
the State of Pennsylvania.

         16. Interpretation. Wherever appropriate in this Agreement, words used
in the singular shall include the plural and the masculine shall include the
feminine gender.

         IN WITNESS HEREOF, the parties have signed this Agreement the day and
year above written.

Board of Directors
HARLEYSVILLE NATIONAL CORPORATION
P.O. Box 195
Harleysville, PA 19438


Ladies and Gentlemen:

         We have acted as Special Counsel to Citizens Bank and Trust Company
("CBTC"), a Pennsylvania chartered bank and trust company, in connection with
the Agreement and Plan of Reorganization, dated as of December __, 1999 (as
amended, the "Agreement"), by and among Harleysville National Corporation
("HNC"), Citizens National Bank ("CNB") and CBTC pursuant to which CBTC will be
merged with and into CNB (the "Bank Merger"). While this firm represents CBTC in
connection with specific legal matters as to which we are consulted by it, we do
not perform or provide legal services to CBTC in connection with the day-to-day
operations of its business or routine legal proceedings related thereto. This
opinion is being delivered to you in accordance with the provisions of Section
6.2(c) of the Agreement.

         This Opinion Letter is governed by, and shall be interpreted in
accordance with, the Legal Opinion Accord of the ABA Section of Business Law
(1991) (the "Accord"). As a consequence, it is subject to the qualifications,
exceptions, definitions, limitations on coverage and other limitations, all as
more particularly described in the Accord, and this Opinion Letter should be
read in conjunction therewith. Except as otherwise indicated herein, capitalized
terms used in this opinion letter are defined as set forth in the Agreement or
the Accord. The law covered by the opinions expressed herein is limited to the
federal law of the United States and the laws of the Commonwealth of
Pennsylvania.

         In connection with the opinions expressed herein, we have examined
originals, or copies certified or otherwise identified to our satisfaction, of
the articles of incorporation, the certificate of incorporation, the certificate
of good standing, the by-laws, the Agreement and such other corporate and other
records, certificates and documents as we have considered necessary or
appropriate for the purposes of rendering the opinions set forth below.



                                      A-4-2
<PAGE>   247
         Based upon and subject to the foregoing and the other terms and
provisions hereof, it is our opinion that:

         1. CBTC is a bank and trust company that is duly organized, validly
existing and in good standing under the laws of the Commonwealth of
Pennsylvania.

         2. CBTC has full corporate power and authority (including all federal,
state, local and foreign governmental authorizations) to carry on its businesses
as it is now being conducted and to own its properties and assets.

         3. The authorized capital stock of CBTC consists of 5,542 shares of
CBTC Common Stock, par value $50.00 per share, all of which are issued and
outstanding. In that regard, we note that although the articles of incorporation
state that CBTC is authorized to issue 6,000 shares of common stock, CBTC,
pursuant to permission granted by the Pennsylvania Department of Banking dated
January 15, 1998, (copy attached hereto), acquired 458 shares of its common
stock which the Department of Banking required CBTC to retire. All of the issued
and outstanding shares of capital stock of CBTC have been duly authorized and
are validly issued, fully paid and nonassessable. CBTC has no shares of capital
stock reserved for issuance.

         4. To our actual knowledge, CBTC has no outstanding bonds, debentures,
notes or other obligations the holders of which have the right to vote (or
convertible into or exercisable for securities having the right to vote) with
shareholders on any matter. The outstanding shares of capital stock of CBTC have
not been issued in violation of any preemptive rights. To our actual knowledge,
there are no outstanding subscriptions, options, warrants, rights, convertible
securities or other agreements or commitments of any character relating to the
issued or unissued capital stock or other securities of CBTC.

         5. To our actual knowledge, CBTC has no subsidiaries.

         6. CBTC has the requisite corporate power and authority to execute and
deliver the Agreement and the Bank Merger Agreement and to carry out the
transactions contemplated therein, and all corporate actions required to be
taken by CBTC to authorize the execution and delivery of the Agreement and the
Bank Merger Agreement and the performance of the transactions contemplated
therein have been taken. The Agreement and the Bank Merger Agreement have been
duly authorized, executed and delivered by CBTC and, assuming due authorization,
execution and delivery by HNC and CNB, and receipt of required regulatory
approvals and the approval of the CNB shareholders, constitutes a valid and
binding obligation of CBTC and is enforceable against it in accordance with its
terms, subject to bankruptcy, insolvency, and other laws of general
applicability relating to or affecting creditors' rights and general equity
principles.

         7. The execution, delivery and performance of the Agreement will not,
and the consummation of the transactions contemplated thereby will not,
constitute (i) a breach or

                                      A-4-3
<PAGE>   248
violation of, or a default under, any law, rule or regulation or any judgment,
decree, order, governmental permit or license, to which CBTC (or any of its
respective properties) is subject, which breach, violation or default would have
a Material Adverse Effect on it, or enable any person to enjoin the Bank Merger,
(ii) a breach or violation of, or a default under CBTC's articles of
incorporation, or its bylaws, or (iii) to our actual knowledge, except as
disclosed in Annex 3.1(e), a breach or violation of, or a default under (or an
event which with due notice or lapse of time or both would constitute a default
under), or result in the termination of, accelerate the performance required by,
or result in the creation of any lien, pledge, security interest, charge or
other encumbrance upon any of the properties or assets of CBTC under any of the
terms, conditions or provisions of any note, bond, indenture, deed of trust,
loan agreement or other agreement, instrument or obligation to which it is a
party, or to which any of its respective properties or assets may be bound, or
affected, except for any of the foregoing that, individually or in the
aggregate, would not have a Material Adverse Effect on it or enable any person
to enjoin the Bank Merger.

         8. The consummation of the transactions contemplated by the Agreement
does not require as to CBTC any approval, consent or waiver under any law, rule,
regulation, judgment, decree, order, governmental permit or license or, to our
actual knowledge, the approval, consent or waiver of any party to any agreement,
indenture or instrument, other than (i) all required approvals, consents and
waivers of governmental authorities, and (ii) the approval of its shareholders
referred to in Section 6.1(a).

         9. Except as set forth in Annex 3.1(j) to the Agreement (i) to our
actual knowledge, there are no civil, criminal or administrative actions, suits,
claims, hearings, investigations or proceedings before any court, governmental
agency or otherwise pending or, threatened against CBTC and (ii) to our actual
knowledge based solely upon written certificates of officers of CBTC, there are
no obligations or liabilities, whether or not accrued (contingent or otherwise,
including, without limitation, those relating to environmental and occupational
safety and health matters, or any other facts or circumstances of which the
management of CBTC is aware that could reasonably be expected to result in any
claims against or obligations or liabilities of CBTC), that, alone or in the
aggregate, are reasonably likely to have a Material Adverse Effect on CBTC or to
hinder or delay, in any material respect, consummation of the transactions
contemplated by the Agreement.

         10. To our actual knowledge, except as set forth in Annex 3.1(k) to the
Agreement, CBTC is not a party to any cease and desist order, written agreement
or memorandum of understanding with, or a party to any commitment letter or
similar undertaking to, or is subject to any order or directive by, or is a
recipient of any extraordinary supervisory letter from, or has adopted any board
resolutions at the request of, federal or state governmental authorities,
including, without limitation, the CBTC Regulatory Agencies, charged with the
supervision or regulation of financial or depository institutions or engaged in
the insurance of bank deposits nor has it been advised by any CBTC Regulatory
Agency that such body is contemplating issuing or requesting (or is considering
the appropriateness of issuing or requesting) any such order,

                                      A-4-4
<PAGE>   249
directive, written agreement, memorandum of understanding, extraordinary
supervisory letter, commitment letter, board resolution or similar undertaking.

         The General Qualifications apply to the opinions expressed at
paragraphs 2 and 7 hereof.

         This opinion is furnished by us as Special Counsel to CBTC solely for
your benefit and solely in connection with the above-described transaction and
for no other purpose. You may not, without our express written approval, deliver
copies of this opinion or extracts therefrom to any other person and no one
other than you is entitled to rely on this opinion. Our opinion is as of the
date hereof, and we undertake no duty to update such opinion after the date
hereof.

                                             Very truly yours,

                                             RHOADS & SINON LLP

Mr. Walter E. Daller, Jr.
President
HARLEYSVILLE NATIONAL CORPORATION
483 Main Street
Harleysville, Pennsylvania 19438



Dear Mr. Daller:

You have requested our advice in regards to certain U.S. federal income tax
consequences of the proposed merger of Citizens Bank and Trust Company into
Citizens National Bank. Our advice is based upon our understanding of the
transaction which is described below:

                                 THE TRANSACTION

         1.       Harleysville National Corporation is a registered multi-bank
                  holding company incorporated in the Commonwealth of
                  Pennsylvania. It has one class of stock outstanding (common
                  stock, $1.00 par value), which is publicly traded over the
                  counter and is commonly quoted on the National Association of
                  Securities Dealers Automated Quotation system for national
                  market issues.

         2.       Harleysville National Bank, Citizens National Bank and
                  Security National Bank are each federally chartered commercial
                  banks regulated by the Office of the Comptroller of the
                  Currency. Each of these three banking subsidiaries has one
                  class of outstanding stock. Harleysville National Bank and
                  Citizens National Bank are wholly owned by Harleysville.
                  Citizens National Bank is, presently, wholly owned by HNC
                  North, Inc. a wholly owned subsidiary of Harleysville National
                  Corporation and a Pennsylvania corporation. All of the
                  companies join with Harleysville National Corporation in the
                  filing of a consolidated federal income tax return on the
                  basis of a calendar taxable year using the accrual method of
                  accounting to compute taxable income. HNC Financial Corp. is
                  another wholly owned subsidiary of Harleysville National
                  Corporation and a Delaware corporation.

         3.       Citizens Bank and Trust Company is a Pennsylvania chartered
                  bank and trust company, subject to regulation by the
                  Pennsylvania Department of Banking. Citizens Bank and Trust
                  Company capital stock trades on a very limited basis in the
                  over-the counter market and is quoted and transactions are
                  reported on the OTC Bulletin Board and in privately negotiated
                  transactions. Citizens Bank and Trust Company files its
                  federal income tax return on the basis of a calendar year-end
                  using the accrual method of accounting.

         4.       Part of Harleysville's business growth plan is the acquisition
                  of smaller community financial institutions that are well
                  known in their local market places, but don't have the
                  organizational strength possessed by Harleysville National
                  Corporation. In keeping with this strategy, the management of
                  Harleysville and the management of Citizens Bank and Trust
                  Company have agreed to a combination to be accomplished
                  pursuant to a plan of merger.

         5.       Pursuant to state corporation law, Harleysville will liquidate
                  its wholly owned subsidiary HNC North and cancel the stock of
                  HNC North in exchange for the assets of HNC North.
                  Harleysville will then own directly 100% of the stock of
                  Citizens National Bank.

         6.       On the date of the complete liquidation of HNC North into
                  Harleysville National Corporation, the fair market value of
                  HNC North's assets will exceed its liabilities.

         7.       After the liquidation of HNC into Harleysville, Citizens Bank
                  and Trust Company will merge into Citizens National Bank with
                  Citizens National Bank surviving, pursuant to state and
                  national banking law. Except for fractional shares and
                  shareholders of Citizens Bank and Trust Company exercising
                  dissenter's rights, Citizens Bank and Trust Company
                  shareholders will exchange all of their Citizens Bank and
                  Trust Company stock solely for stock of Harleysville. Citizens
                  Bank and Trust Company stock will then be canceled. Citizens
                  National Bank will continue to operate the commercial banking
                  business of Citizens Bank and Trust Company through an un-
                  incorporated division.

         8.       There is a valid business purpose for each of the steps of the
                  transaction described above.




                                      B-3
<PAGE>   257
         9.       Prior to the merger, HNC Financial Corporation, a wholly owned
                  subsidiary of Harleysville National Corporation, owns 2.76% of
                  the common stock of Citizens National Bank and Trust
                  Corporation. Neither Harleysville National Corporation nor any
                  of its other subsidiaries presently owns or has ever owned any
                  of the stock of Citizens National Bank and Trust Company.

         10.      At the time of the liquidation of HNC North, Harleysville will
                  own at least 80% of the voting power or at least 80% of the
                  total number of shares of any class of HNC North outstanding.

         11.      One hundred percent of HNC North stock will be cancelled after
                  the distribution of HNC North assets to Harleysville in the
                  liquidation.

         12.      The complete distribution of HNC North assets to Harleysville
                  will occur within the same taxable year.

         13.      The fair market value of Harleysville stock to be received by
                  former shareholders of Citizens Bank and Trust Company in
                  exchange for their shares of Citizens Bank and Trust Company
                  stock will be approximately equal to the fair market value of
                  that Citizens Bank and Trust Company stock.

         14.      No Citizens National Bank stock will be issued in the
                  transaction.

         15.      As a result of this merger, Citizens National Bank will
                  acquire at least 90% of the fair market value of Citizens Bank
                  and Trust Company's net assets and at least 70% of the fair
                  market value of its gross assets held immediately prior to the
                  transaction. Amounts used by Citizens Bank and Trust Company
                  to pay reorganization expenses, and all redemptions and
                  distributions (except for regular, normal dividends) made by
                  Citizens Bank and Trust Company will be included as assets
                  held immediately prior to the transaction.

         16.      Citizens National Bank has no intention to issue additional
                  shares of its stock that would result in HNC North (before its
                  complete liquidation) or Harleysville (after the complete
                  liquidation of HNC North) owning less than 80% of the voting
                  power or less than 80% of the total number of shares of any
                  class of Citizens National Bank outstanding stock.

         17.      Neither Harleysville nor any party related to it has any
                  intention to reacquire any Harleysville stock issued to the
                  shareholders of Citizens Bank and Trust Company in the merger.




                                      B-4
<PAGE>   258
         18.      Harleysville has no intention to liquidate Citizens National
                  Bank or cause the merger of Citizens National Bank into any
                  other corporation.

         19.      Harleysville has no intention to cause Citizens National Bank
                  to sell or otherwise dispose of any of its assets, except for
                  transfers made in the ordinary course of its business or
                  transfers of its assets to a corporation directly controlled
                  by Citizens National Bank by means of Citizens National Bank's
                  ownership of at least 80% of the voting power and 80% of the
                  total number of shares of all classes of outstanding stock of
                  the corporation.

         20.      Each corporation and all shareholders, will each pay all of
                  their own expenses associated with the liquidation and the
                  merger.

         21.      None of the corporations is a regulated investment company, a
                  real estate investment trust or a corporation with 50% or more
                  of the value of its total assets comprised of stock or
                  securities and 80% or more of the value of its total assets
                  being held for investment (other than stock or securities in a
                  corporation at least 50% of the voting or 50% of the value of
                  the stock of which is owned by the first corporation in which
                  case the first corporation will be deemed to own its ratable
                  share of the second corporation's assets).

         22.      None of the corporations is under the jurisdiction of a court
                  in a Title 11 or similar case.

         23.      None of the compensation received by any employee of Citizens
                  Bank and Trust Company will be separate consideration for, or
                  allocable to, any of the shares of Citizens Bank and Trust
                  Company stock owned by the employee. Likewise, none of the
                  shares of Harleysville stock received by any employee of
                  Citizens Bank and Trust Company will be in payment for
                  employment. All compensation paid to employees of Citizens
                  Bank and Trust Company will be for services actually rendered
                  and will be comparable to amounts commonly paid to other
                  employees for similar services.

         24.      Immediately after the merger, Citizens National Bank will not
                  have outstanding any warrants, options, convertible securities
                  or any other type of right which would permit any person to
                  acquire stock of Citizens National Bank that will cause
                  Harleysville to own less than 80% of the voting power or less
                  than 80% of the total number of outstanding shares of all
                  classes of stock outstanding.




                                      B-5
<PAGE>   259
         25.      The merger of Citizens Bank and Trust Company into Citizens
                  National Bank will constitute a merger under applicable state
                  or federal law.

         26.      The payment of cash in lieu of fractional shares of
                  Harleysville stock is solely for the purpose of avoiding the
                  expense and inconvenience of issuing fractional shares. The
                  total amount of cash that will be paid to former shareholders
                  of Citizens Bank and Trust Company instead of fractional
                  shares of Harleysville stock will not exceed 1% of the value
                  of the total amount of cash and stock that will be issued in
                  the merger to the former shareholders of Citizens Bank and
                  Trust Company in exchange for their shares of Citizens Bank
                  and Trust Company stock.

         27.      The fair market value of Citizens Bank and Trust Company's and
                  Citizens National Bank's assets exceed the sum of their
                  respective liabilities and any liabilities to which their
                  assets are subject.

         28.      Citizens Bank and Trust Company has not bought back any of its
                  stock in the last two calendar years.

         29.      All liabilities assumed by Citizens National Bank in the
                  merger and all the liabilities collateralized by the assets of
                  Citizens Bank and Trust Company were incurred by Citizens Bank
                  and Trust Company in the ordinary course of its business.

         30.      Citizens Bank and Trust Company's only outstanding stock is
                  its common stock. None of the debt of Citizens Bank and Trust
                  Company is considered stock for U.S. federal income tax
                  purposes.

         31.      No liabilities, either fixed or contingent, of Citizens Bank
                  and Trust Company or of Citizens Bank and Trust Company's
                  shareholders will be assumed by Harleysville.

         32.      No indebtedness exists between Harleysville, or any of its
                  subsidiaries, and Citizens Bank and Trust Company that was
                  issued, acquired, or will be settled at a discount.

                                   CONCLUSIONS

         Based upon the description of the transaction above and subject to the
         limiting conditions set out below, we are of the opinion that for U.S.
         federal income tax purposes:

         1.       No gain or loss will be recognized by Harleysville upon the
                  receipt of HNC North assets in the liquidation.

         2.       No gain or loss will be recognized by HNC North on the
                  distribution of its assets to Harleysville or the cancellation
                  of its stock.

         3.       The merger of Citizens Bank and Trust Company with and into
                  Citizens National Bank will constitute a tax-free
                  reorganization for U.S. federal income tax purposes.

         4.       No gain or loss will be recognized by the former shareholders
                  of Citizens Bank and Trust Company upon the exchange of their
                  Citizens Bank and Trust Company stock for Harleysville stock.

         5.       The basis and holding periods of former Citizens Bank and
                  Trust Company shareholders in their Citizens Bank and Trust
                  Company stock will carry over to the Harleysville stock they
                  receive in the merger provided that the shares of Citizens
                  Bank and Trust Company stock were held by them as capital
                  assets on the date of the transaction.

         6.       Former Citizens Bank and Trust Company shareholders receiving
                  cash in lieu of fractional shares of Harleysville stock will
                  have gain or loss on such exchanges equal to the excess of the
                  cash received in lieu of such fractional shares over the
                  shareholder's basis in Citizens Bank and Trust Company stock
                  allocable to the fractional shares. That gain or loss will be
                  capital gain or loss, if the shares of Citizens Bank and Trust
                  Company stock qualified as capital assets in the hands of the
                  exchanging shareholder. The capital gain or loss will be long
                  term if the shareholders holding period for the stock is more
                  than one year and short term if not.

         7.       Former Citizens Bank and Trust Company shareholders exercising
                  dissenter's rights will have gain or loss on the receipt of
                  cash for their Citizens Bank and Trust Company shares equal to
                  the excess of the cash received over their basis in their
                  Citizens Bank and Trust Company stock. That gain or loss will
                  qualify as capital gain or loss, if the shares of Citizens
                  Bank and Trust Company stock qualified as capital assets in
                  the







                                      B-7
<PAGE>   261
                  hands of the exchanging shareholder and, the capital gain or
                  loss will be long term if the shareholder's holding period for
                  the shareholder's Citizens Bank and Trust Company stock is
                  more than one year and short term if not.

         8.       No gain or loss will be recognized by Citizens National Bank
                  upon the receipt of Citizens Bank and Trust Company's assets
                  and liabilities in the merger. The basis and holding period of
                  Citizens Bank and Trust Company in its assets transferred to
                  Citizens National Bank will carryover to Citizens National
                  Bank and become Citizens National Bank's basis and holding
                  period in those assets.

         9.       Citizens National Bank will succeed to the tax attributes of
                  Citizens Bank and Trust Company including net operating loss
                  carryovers, credit carryovers and accounting methods.

         10.      Harleysville will not recognize gain or loss on the merger of
                  Citizens Bank and Trust Company into Citizens National Bank.
                  Harleysville's basis in its Citizens National Bank stock will
                  be increased by the basis of Citizens Bank and Trust Company
                  in its net assets immediately prior to the merger of Citizens
                  Bank and Trust Company with and into Citizens National Bank.

         description of the transaction without independent verification. Our

         transaction are dependent upon the accuracy of that description and

                       EXCERPTS FROM, SECTION 215a OF THE
                NATIONAL BANK ACT RELATING TO DISSENTERS' RIGHTS

                  (b) 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 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
         shares 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) 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) 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.

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

               Section 215(b)(4) of the National Bank Act defines the term
         "receiving association," as used in Section 215a, to mean the national
         banking association into which one or more national banking
         associations or one or more State banks, located within the same State,
         merge.

                   Tucker Anthony Cleary Gull Fairness Opinion





                                       D-1
<PAGE>   267




         Board of Directors
         Citizens Bank & Trust Company
         372 Delaware Avenue
         Palmerton, PA  18071

         Ladies and Gentlemen:

                  You have requested our opinion, as investment bankers, as to
         the fairness, from a financial point of view, of the terms of the
         proposed merger (the "Merger") of Citizens Bank & Trust Company
         ("Citizens") with and into Harleysville National Corporation
         Corporation ("Harleysville"). Pursuant to the Agreement and Plan of
         Reorganization dated December 28, 1999 between Citizens and
         Harleysville (the "Merger Agreement"), each share of Citizens Common
         Stock outstanding at the Effective Time of Merger will be converted
         into the right to receive (the "Merger Consideration") 166 shares of
         Harleysville Common Stock (the "Exchange Ratio").

                  Hopper Soliday, a division of Tucker Anthony Incorporated
         ("Hopper Soliday"), as a customary part of its investment banking
         business, is engaged in valuing businesses and their securities in
         connection with mergers and acquisitions, stock purchase offers,
         negotiated underwritings, secondary distributions of securities,
         private placements and for estate, corporate reorganization and other
         purposes.

                  Hopper Soliday reviewed, among other things: i) Citizens'
         audited financial statements and related financial information for
         years ended December 31, 1994 through December 31, 1998 and Citizens'
         quarterly financial statements on for the periods ending March 31,
         1999, June 30, 1999 and September 30, 1999; ii) Harleyville's Annual
         Reports on Form 10-K and related financial information for years ended
         December 31, 1994 through December 31, 1998 and Quarterly Reports on
         Form 10-Q for the periods ending March 31, 1999, June 30, 1999 and
         September 30, 1999; iii) certain information concerning the respective
         businesses, operations, regulatory condition and prospects of
         Harleysville and Citizens, including financial forecasts, relating to
         the business, earnings, assets and prospects of Harleysville and
         Citizens, furnished to Hopper Soliday by Harleysville and Citizens,
         which Hopper Soliday discussed with members of senior management of
         Harleysville and Citizens; iv) historical market prices and trading
         activity for the Harleysville Common Stock and Citizens Common Stock
         and









                                      D-2
<PAGE>   268


         similar data for certain publicly traded companies which Hopper Soliday
         deemed to be relevant; v) the results of operations of Harleysville and
         Citizens and similar data for certain companies which Hopper Soliday
         deemed to be relevant; vi) the financial terms of the Merger
         contemplated by the Merger Agreement and the financial terms of certain
         other mergers and acquisitions which Hopper Soliday deemed to be
         relevant; vii) the pro forma impact of the Merger on the earnings and
         book value per share, consolidated capitalization and certain balance
         sheet and profitability ratios of Harleysville; viii) the Merger
         Agreement; and ix) such other matters as Hopper Soliday deemed
         necessary. Hopper Soliday also met with certain members of senior
         management and other representatives of Harleysville and Citizens to
         discuss the foregoing as well as other matters Hopper Soliday deemed
         relevant.

                  In conducting our review and in arriving at our opinion, we
         relied upon and assumed the accuracy and completeness of the financial
         and other information provided to us or that which was publicly
         available and did not attempt independently to verify such information.
         We relied upon the managements of Citizens and Harleysville as to the
         reasonableness and achievability of the financial and operating
         forecasts and projections (and the assumptions and bases thereof)
         provided to us and assumed that such forecasts and projections
         reflected the best currently available estimates and judgements of such
         managements and that such forecasts and projections would be realized
         in the amounts and in the time periods estimated by such managements.
         We also assumed, without independent verification, that the aggregate
         allowances for loan losses for Citizens and Harleysville were adequate.
         We did not make or obtain any evaluations or appraisals of the assets
         of Citizens and Harleysville, nor did we examine any individual loan
         credit files. Our opinion is limited to the fairness, from a financial
         point of view, to the shareholders of Citizens of the Merger
         Consideration.

                  In rendering our opinion we have assumed that in the course of
         obtaining the necessary regulatory approvals for the Merger, no
         conditions will be imposed that will have a material adverse effect on
         the contemplated benefits of the Merger to either Citizens or, on a pro
         forma basis, the resulting company following the Merger. Our opinion
         necessarily is based upon conditions as they exist on, and can be
         evaluated as of, the date of this letter.

                  On the basis of the aforementioned analysis, and subject to
         the qualifications described above, as of the date hereof, we are of
         the opinion that the Merger Consideration provided for by the Merger
         Agreement is fair to the shareholders of Citizens from a financial
         point of view.

         Sincerely,



         Hopper Soliday, a Division of Tucker Anthony Incorporated

business corporation has the power under certain circumstances to indemnify its
directors, officers, employees and agents against certain expenses incurred by
them in connection with any threatened, pending or completed action, suit or
proceeding.

         Article 10 of the Amended Bylaws of Harleysville provides for the

Item 22.          Undertakings.

         (a)

         1.      The undersigned Registrant hereby undertakes as follows:

                 (A) 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; (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; (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;

                     Provided, however, that paragraphs (1)(a)(i) and (1)(a)(ii)
above do not apply if the registration statement is on Form S-3 or Form S-8 and
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registration pursuant
to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in the registration statement.

                 (B) That, for the purpose of determining any liability under
the Securities Act, 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.

                 (C) 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.

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

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



                                      II-4
<PAGE>   273
items of the applicable form.

            The registrant undertakes that every prospectus (i) that is
filed pursuant to the preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Act 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, each such post-operative 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.

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

         (b) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of this Form, within one (1) 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.

         (c) The undersigned registrant hereby undertakes to supplement 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.

            RE:      Harleysville National Association/Citizens Bank and
                     Trust Company Our File No: 99-853

Dear Messrs Daller and Wimmer:

         We are special counsel to Harleysville National Corporation
(the"Company") in the Company's acquisition of Citizens Bank and Trust Company
(the "Bank"). In connection with the transaction, the Company proposes to offer
up to 919,972 shares of common stock, par value $1.00 per share (the "Common
Stock"), to shareholders of the Bank. The Common Stock is covered by a
Registration Statement on Form S-4 (the "Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended.
In connection with the registration of the Common Stock, we have reviewed:

         1.       The Articles of Incorporation of the Company;

         2.       The Bylaws of the Company;

         3.       Resolutions adopted by the Board of Directors of the Company
                  relating to the Registration Statement, certified by the
                  Secretary of the Company;

         4.       The Agreement and Plan of Reorganization, dated as of December
                  28, 1999, by and among the Company, Citizens National Bank and
                  Citizens Bank and Trust Company (the "Agreement");
         5.       The Registration Statement; and



<PAGE>   2



         6. Copies of the certificates representing shares of the Common Stock.

         Based on our review of the foregoing, it is our opinion that:

                  a.       The Company is a corporation, duly organized and in
                           good standing under the laws of the Commonwealth of
                           Pennsylvania; and

                  b.       The Common Stock covered by the Registration
                           Statement has been duly authorized and, when issued
                           pursuant to the terms described in the Registration
                           Statement and the Agreement, will be legally issued
                           by the Company and fully paid and non-assessable.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to us in the related Proxy
Statement/Prospectus. In giving this consent, we do not admit that we are
experts within the category of persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.

                                                     Very truly yours,

                                                     /s/ Shumaker Williams, P.C.

Dear Shareholder:

         You are invited to attend a special meeting of the shareholders of
Citizens Bank and Trust Company. This special meeting will be held on Friday,
April 7, 2000, at 10:00 a..m., at the main office of the Bank, 372 Delaware
Avenue, Palmerton, Pennsylvania 18071. The main purpose of the meeting is to
vote on the merger of your Bank into Citizens National Bank, a subsidiary of
Harleysville National Corporation, a bank holding company located in
Harleysville, Montgomery County, Pennsylvania. If the merger is completed, you
will receive 166 shares of Harleysville common stock in exchange for each of
your shares of Citizens capital stock. The exchange of Citizens stock for
Harleysville stock will be tax-free to Citizens shareholders for federal income
purposes. Completion of the merger is subject to certain conditions. The two
principal conditions that the merger must meet are that the shareholders of
Citizens Bank and Trust Company approve the merger and that certain banking
regulatory agencies approve the merger.

         The attached notice of special meeting and proxy statement/prospectus
describe the formal business to be transacted at the meeting. The directors and
officers of Citizens will be present at the meeting to respond to any questions
from our shareholders.

         We urge you to carefully read the enclosed proxy statement/prospectus
that describes the merger in detail and the requirements needed to complete the
merger. The information contained in the "SUMMARY" portion of the proxy
statement/prospectus gives a basic description of the merger. If you have any
questions after a review of the proxy statement/prospectus consult with your own
advisors or contact James A. Wimmer, President, telephone (610) 826-2457.

         Tucker Anthony Cleary Gull, Citizens' investment banker, provided the
Board of Directors with an opinion that the consideration to be received by the
shareholders in the merger transaction is fair from a financial point of view.

         Your Board of Directors believes that the merger is in the best
interests of the Bank and its shareholders and recommends that you vote FOR the
merger.

                                             Sincerely yours,

                                             James A. Wimmer
                                             Chairman and President

                          NOTICE OF SPECIAL MEETING OF
                    SHAREHOLDERS TO BE HELD ON APRIL 7, 2000

         NOTICE IS HEREBY GIVEN that a Special Meeting of Shareholders of
Citizens Bank and Trust Company will be held at 10:00 a..m., Eastern Standard
Time, on Friday, April 7, 2000, at the main office of the Bank, 372 Delaware
Avenue, Palmerton, Pennsylvania 18071. We enclose a form of proxy and a proxy
statement/prospectus for the meeting.

         We are holding the meeting for the purpose of considering and acting
upon the following matters:

         1.       Approval and adoption of the Agreement and Plan of
                  Reorganization, dated as of December 28, 1999, by and among
                  Harleysville National Corporation, Citizens National Bank and
                  Citizens Bank and Trust Company. The agreement provides that
                  Citizens Bank and Trust Company will merge into The Citizens
                  National Bank. Upon completion of the merger, each Citizens
                  Bank and Trust Company shareholder will have the right to
                  receive 166 shares of Harleysville common stock, in exchange
                  for each share of capital stock of Citizens held by the
                  shareholder; and

         2.       Other matters as may properly come before the meeting and any
                  adjournment or postponement of the meeting.

         We may take action on the proposal at the meeting or on any dates to
which we may adjourn the meeting. Only those shareholders whose ownership
appears on the shareholder records of Citizens Bank and Trust Company at the
close of business on February 11, 2000, will be entitled to receive notice of
the meeting and to vote at the meeting.

         Your Board of Directors believes that this merger is in the best
interests of the Bank and its shareholders. Our reasons for this belief are
provided in the enclosed proxy statement/prospectus. We urge you to vote for the
merger. Your participation at the meeting, in person or by sending in a
completed proxy, is important. We need the affirmative vote of at least
two-thirds (66.7%) of the outstanding shares of common stock to approve the
merger.
         If you do not send in a completed proxy or you do not attend the
meeting and vote, it has the same effect as voting against the merger.
Therefore, we urge you to complete, sign, date and

<PAGE>   2


return the enclosed form of proxy in the enclosed postage-paid envelope as soon
as possible so that your shares will be voted at the meeting. If you do attend
the meeting and wish to vote in person, you can do so by giving written notice
to the Secretary of the meeting. Your ballot at the meeting will replace your
proxy.

         On behalf of the Board of Directors, I thank you for your support and
recommend that you vote "FOR" approval of the agreement and merger.


                                           By Order of the Board of Directors,



                                           James A. Wimmer
                                           Chairman and President
