of  Lansford  will  survive  the  merger  and  conduct  business  under the name
"Citizens  National  Bank,"  and  as  a  subsidiary  of  Harleysville   National
Corporation North, Inc.

     We  attach  a copy of the  agreement  as Annex A to this  proxy  statement/
prospectus. Please read the agreement carefully.

Certain Terms of the Merger

     The merger is subject to various  conditions,  including,  among others:  o
approval by Northern  Lehigh's  shareholders;  and o approval by certain banking
regulatory agencies;

     The  transaction is also subject to various other  conditions  contained in
the agreement.  These  conditions  include that the merger qualify for a certain
type of accounting treatment. In the event that more than 10% of the outstanding
shares of Northern Lehigh exercise  dissenters' rights, the accounting condition
will not be met. If this occurs, the merger will not be completed. See "APPROVAL
OF THE MERGER--Accounting Treatment."

     Harleysville  National  Corporation and Northern  Lehigh Bancorp,  Inc. may
agree to amend the agreement.  No amendment,  however,  can affect the number of
shares to be received by Northern  Lehigh  shareholders  without the approval of
the Northern  Lehigh  shareholders.  The agreement and merger will  terminate on
June 30, 1999,  unless  extended by the mutual  agreement  of the  parties.  See
"APPROVAL OF THE MERGER--Business Pending the Merger."

Comparison of Shareholder Rights

     On the day the merger is completed,  the  shareholders  of Northern  Lehigh
will become shareholders of Harleysville National  Corporation.  Northern Lehigh
and   Harleysville   National   Corporation  are  each   Pennsylvania   business
corporations.  After the  merger is  completed,  the  rights of former  Northern
Lehigh shareholders will continue to be governed by Pennsylvania law, as well as
the articles of incorporation and bylaws of Harleysville  National  Corporation.
Certain  differences  exist in the rights of the shareholders of Northern Lehigh
and Harleysville National Corporation.  These differences are due in part to the
differences in the Articles of Incorporation

                                       -3-

<PAGE>

and Bylaws of Northern  Lehigh and the Articles of  Incorporation  and Bylaws of
Harleysville National Corporation.

     The most significant  differences between the rights of the shareholders of
Northern Lehigh and of shareholders of Harleysville National Corporation include
the following:

     *    although  the  Boards of  Directors  of each of  Northern  Lehigh  and
          Harleysville   National   Corporation  are  classified  or  staggered,
          approximately  one-third  of the  directors  of  Northern  Lehigh  are
          elected  each  year  for   three-year   terms  while   one-fourth   of
          Harleysville  National  Corporation's  directors are elected each year
          for four-year terms;

     *    certain  anti-takeover  items are contained in  Harleysville  National
          Corporation's  Articles  of  Incorporation,  which  may  serve to keep
          Harleysville  National   Corporation's  current  management  in  their
          positions.  Northern Lehigh's  Articles of Incorporation  contain some
          similar items but there are certain differences in these anti-takeover
          items;

     *    Harleysville  National Corporation offers a dividend reinvestment plan
          to its  shareholders,  while  Northern  Lehigh  offers no plan of this
          type; and

     *    Harleysville National Corporation common stock is registered under the
          Securities  Exchange Act of 1934 and is traded on the Nasdaq  National
          Market System,  while  Northern  Lehigh common stock is not registered
          under the Securities  Exchange Act of 1934, and is traded on a limited
          basis in the  over-the-counter  market, and is quoted and transactions
          are reported on the OTC Bulletin Board.

Rights."

Federal Income Tax Consequences of the Merger

     Northern  Lehigh  and  Harleysville  National  Corporation  structured  the
transaction to qualify as a tax-free  reorganization  under the Internal Revenue
Code of 1986. Under the Internal Revenue Code, Northern Lehigh shareholders will
not  recognize  taxable gain or loss upon the receipt of  Harleysville  National
Corporation common stock in exchange for Northern Lehigh common stock.  Northern
Lehigh  shareholders  who receive  cash for  fractional  shares of  Harleysville
National  Corporation  common stock will recognize  taxable gain or loss,  based
upon the amount of cash  received.  Northern  Lehigh  shareholders  who exercise
dissenters'  rights  also  will  recognize  taxable  gain or loss  based  on the
difference  between the amount of cash received by the  shareholders in exercise
of  dissenters'  rights  and the  adjusted  tax basis of the  shares as to which
dissenters' rights are exercised.  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.  You should consult with your own
tax advisers  regarding that tax consequences of the merger with respect to your
own particular circumstances. See, "APPROVAL OF THE MERGER -- Federal Income Tax
Consequences."

Accounting Treatment

     Northern  Lehigh and  Harleysville  National  Corporation  intend  that the
transaction  be accounted for as a pooling of interests for financial  reporting
purposes. This means that we will treat the companies as if they had always been
combined for accounting and financial reporting purposes.

Dissenters' Rights

     The Pennsylvania  Business Corporation Law of 1988 provides Northern Lehigh
Bancorp,  Inc.  shareholders  with the right to dissent from the merger,  and to
demand and  receive  the "fair  value" of their  shares of stock  instead of the
Harleysville  National Corporation common stock to be received in the merger. In
order to assert these dissenters' rights, you must:

     *    file a written notice of intent to dissent with Northern  Lehigh prior
          to the shareholder vote at the meeting;

     *    not vote in favor of the merger;

     *    file a  written  demand  for  payment  and  deposit  the  certificates
          representing  your shares as requested by the notice to demand payment
          that  will  be  sent  by  Northern  Lehigh  or  Harleysville  National
          Corporation; and

     *    comply  with  certain  other   statutory   procedures   set  forth  in
          Pennsylvania law.

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 may have with respect to the merger.  A copy of the  applicable  sections of
the  Pennsylvania  Business  Corporation  Law of 1988 are attached to this proxy
statement/prospectus as Annex C.

     If you do not follow the procedures  set forth in the statutory  provisions
of the Pennsylvania  law, you may lose your  dissenters'  rights with respect to
the merger. We urge you to read carefully  "APPROVAL OF THE  MERGER--Dissenters'
Rights" and Annex C to this proxy statement/prospectus.

date, the directors and officers of Northern Lehigh and persons or entities that
they control own 22,674 shares of Northern Lehigh common stock, or 16.25% of the
outstanding  shares.  Northern  Lehigh  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 Northern  Lehigh  common stock
outstanding  as of November 16, 1998,  will be necessary to have a quorum at the

Management and Operations Following the Merger

     Following  the merger,  the Board of  Directors  of  Harleysville  National

Adjournment of the Meeting

     If not enough votes are voted to approve the merger,  the  Northern  Lehigh
Board of Directors intends to postpone or adjourn the meeting to a later date to
permit additional  affirmative  votes to be obtained.  The affirmative vote of a
majority  of the shares is  required  to approve an  adjournment.  The  Northern
Lehigh Board of Directors  recommends that  shareholders vote "FOR" the proposal
to adjourn the meeting, if necessary,  to permit additional votes to be obtained
to approve the agreement.

Opinion of Financial Advisor

     The Northern  Lehigh Board of Directors  asked Hopper  Soliday & Co., Inc.,
its investment banking firm located at 1703 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  National
Corporation  common stock to be received by the Northern Lehigh  shareholders in
the merger is fair,  from a financial point of view.  Hopper Soliday  negotiated
the  financial  terms to be received by Northern  Lehigh's  shareholders  in the
transaction,  on behalf of Northern  Lehigh's Board of Directors.  Your Board of
Directors  considered  and  approved  the  terms of the  merger,  including  the
financial terms.  Hopper Soliday did not approve the financial or other terms of
the merger.  In writing its opinion Hopper Soliday  considered  various factors,
including Northern Lehigh's and Harleysville  National  Corporation's  operating
results,   current  financial  condition  and  perceived  future  prospects.  We
recommend  that you read the Hopper Soliday  opinion,  which is attached to this
proxy  statement/prospectus  as Annex  B. You  should  read the  opinion  in its
entirety and pay particular  attention to the assumptions made and other matters
considered  by Hopper  Soliday in rendering  its opinion.  See  "APPROVAL OF THE
MERGER--Opinion of Financial Advisor."

Recommendation of the Board of Directors

     Your Northern Lehigh Board of Directors  believes that the merger is in the
best interests of you and all  shareholders.  We recommend that the shareholders
vote "FOR" approval of the merger.

                           FORWARD LOOKING STATEMENTS

     This  proxy   statement/prospectus   contains  and   incorporates   certain
statements that constitute  "forward-looking  statements"  within the meaning of
the Private  Securities  Litigation  Reform Act of 1995.  These  forward-looking
statements  include  certain  statements  regarding  intent,  belief or  current
expectations   about   matters   (including    statements   as   to   "beliefs,"
"expectations," "anticipations," "intentions" or similar words). Forward-looking
statements  are also  statements  that are not  statements of  historical  fact.
Forward-looking  statements are subject to risks, uncertainties and assumptions.
These include:

     *    trends  for the  continued  growth  of the  business  of  Harleysville
          National Corporation and Northern Lehigh;

     *    the  realization  of  anticipated  revenues,  profitability  and  cost
          savings of the combined companies; and

     *    other risks and uncertainties.

If one or more of  these  risks or  uncertainties  occurs  or if the  underlying
assumptions prove incorrect, actual results, performance or achievements in 1999
and beyond could differ  materially  from those expressed in, or implied by, the
forward-looking statements.


                           COMPARATIVE PER SHARE DATA

     General

     The following  table  contains  selected  combined and equivalent per share
data for each of  Harleysville  National  Corporation  and Northern  Lehigh on a
historical  basis, and selected  unaudited pro forma  comparative per share data
assuming  the  transaction  had  been  consummated  as of the  beginning  of the
earliest period  presented for earnings per share and dividends per share and as
of the end of the period  presented  for book value per share.  The  information
shows how a share of Northern Lehigh stock that you hold would have participated
in the income  from  continuing  operations,  cash  dividends  and book value or
Harleysville  National  Corporation if the merger had been complete in 1997. The
pro forma data is not  necessarily  indicative  of results  that would have been
achieved had the  transaction  been  consummated  on such date and should not be
construed as  representative  of future  operations.  The information  presented
should  be  read in  conjunction  with  the  historical  consolidated  financial
statements,  and notes to the financial  statements,  of  Harleysville  National
Corporation and Northern Lehigh incorporated by reference or appearing elsewhere
in this proxy statement/prospectus.

                                   THE MEETING
General

     The  Board  of   Directors   of  Northern   Lehigh   provides   this  proxy
statement/prospectus  to Northern Lehigh's  shareholders for a meeting that will
be held at 510 Main Street,  (next to The Citizens National Bank of Slatington's
Main Office),  Slatington,  Pennsylvania 18080 on Thursday,  January 14,1999, at
1:00 p.m.

     At the meeting, Northern Lehigh's stockholders will consider and vote on :

     *    the  approval  and  adoption of the  agreement  that  provides for the
          merger;

     *    the approval of the adjournment or postponement of the meeting, in the
          event there are not enough votes to approve the  agreement and merger;
          and

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

     Northern Lehigh will merge with Harleysville  National  Corporation  North.
When the merger is  completed  Northern  Lehigh will cease to exist and Northern
Lehigh's   shareholders  will  receive  3.57  shares  of  Harleysville  National
Corporation  common stock in exchange for each share of Northern  Lehigh  common
stock that they hold.  Harleysville  National  Corporation  North,  the combined
entity,  will  continue  business  as  a  subsidiary  of  Harleysville  National
Corporation.  A vote for approval of the agreement is a vote for approval of the
merger of Northern Lehigh into Harleysville  National  Corporation North and for
the  exchange  of  Northern  Lehigh  common  stock  for  Harleysville   National
Corporation common stock.

     To  complete  the  merger,  at least 66 2/3% of the  outstanding  shares of
Northern Lehigh Bancorp, Inc. must vote to approve the merger.

Voting, Revocation and Solicitation of Proxies

     At least a majority of the total number of shares of Northern Lehigh common
stock  outstanding on November 16, 1998 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. As of November 16, 1998, there were 139,498 shares
of Northern Lehigh common stock outstanding and entitled to vote. 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:

     *    delivery of a notice of revocation or of a later-dated proxy to Andrea
          M. Beltz,  Secretary,  Northern Lehigh Bancorp, Inc., 502 Main Street,
          Slatington, Pennsylvania 18080; or

                                      -17-

<PAGE>
     *    your attendance at the meeting and your  notification to the person in
          charge of the meeting 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 Northern Lehigh intends to adjourn the meeting to another place and
time  without  further  notice  to the  shareholders.  If for any  other  reason
Northern  Lehigh  believes  additional time should be allowed to obtain proxies,
Northern  Lehigh may adjourn the meeting with a vote of a majority of the shares
outstanding.  If Northern  Lehigh  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.  A proxy that withholds authority or that
is voted  against  the merger will not be voted in favor of any  adjournment  or
postponement of the meeting.

     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  management  of
Northern  Lehigh.  Proxies  marked as  abstentions  will not be counted as votes
cast.  Shares  held by  brokerage  companies  or in  street  name 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, Northern Lehigh will:

     *    bear the cost of soliciting proxies;
   
     *    reimburse   brokerage  firms  and  other   custodians,   nominees  and
          fiduciaries for their reasonable expenses; and

     *    may, if they so decide,  solicit proxies personally or by telegraph or
          telephone.

Voting Securities and Securities Ownership

     Only those  shareholders  whose ownership appears on the shareholder record
of Northern  Lehigh  Bancorp,  Inc. as of the close of business on November  16,
1998, are entitled to vote at the meeting.  Each share of Northern Lehigh common
stock is entitled to one vote. On November 16, 1998,  there were 139,498  shares
of Northern Lehigh common stock outstanding. Common stock is the only issued and

Background of the Merger, Reasons and Recommendation of the Board of Directors

     Background

     Northern  Lehigh's  Board of  Directors  for  several  years as part of its
long-range  planning  practices,  periodically  reviewed and  evaluated  various
strategic  options and available  alternatives to maximize the economic benefits
for Northern Lehigh and its shareholders.  This review and evaluation included a
possible  merger.  The Board has considered  the merits of maintaining  Northern
Lehigh's independence,  Northern Lehigh combining with a smaller or similar size
bank or holding  company,  or merging Northern Lehigh with a larger community or
regional financial institution.  This long-range plan was done annually in light
of current  economic,  financial and regulatory  conditions and their impact and
likely  future  ramifications  for Northern  Lehigh  specifically  and the local
financial services industry.

     After careful  analysis,  and based on expert advice,  the Board  concluded
that in today's financial  services industry  environment  Northern Lehigh could
compete more effectively in its

market area as part of a larger  financial  institution  (which offered Northern
Lehigh,  its  customers,  community  and  employees  certain  benefits)  because
Northern Lehigh would be better able to provide larger financial  accommodations
and additional financial services and products to its customers.

     During its planning and merger analysis, the Board kept clearly in mind the
possible  increase  in the value and  liquidity  of the stock  held by  Northern
Lehigh's shareholders which would come from arranging a merger in which Northern
Lehigh's  shareholders  would  obtain a more widely  publicly-traded  stock in a
larger community bank holding company.  In addition,  during its  deliberations,
the Board also was aware of the economic  effect that a merger could have on the
community of Slatington,  Pennsylvania  and its geographic  contiguous area. The
economic and social  ramifications  of a merger on Northern  Lehigh's  officers,
employees  and  customers  were also of concern to the Northern  Lehigh Board of
Directors during their merger analysis.

     Thus, Northern Lehigh's Board considered whether in a merger transaction it
would be possible to reasonably  assure that, for the  foreseeable  future,  The
Citizens National Bank of Slatington's banking offices would continue to be open
and that the Slatington community and surrounding  geographic area would be able
to  continue  to obtain at least  similar  or  improved  banking  and  financial
services,  the directors,  officers and employees  would continue to be employed
and, if  possible,  that the  "Citizens  National  Bank" name and  tradition  of
community bank service which The Citizens  National Bank of Slatington  began at
the turn of the century would  continue  into the next century.  It was with the
foregoing  considerations  in mind that the  Northern  Lehigh Board of Directors
examined all possible  alternatives  and the Harleysville  National  Corporation
merger proposal.

     The Board retained Hopper  Soliday,  as its investment  banker,  to aid the
Northern Lehigh Board of Directors in its examination and evaluation of possible
merger transactions and, if appropriate,  take a leading role in the discussions
with each potential merger participant and, in certain circumstances, the merger
negotiations.

     For the reasons outlined below, the Board  unanimously  agreed to recommend
the  Harleysville   National  Corporation  merger  transaction  for  shareholder
approval.  The Board of Directors has received an opinion from Hopper Soliday to
the  effect  that  the  terms  of  the  agreement  with  Harleysville   National
Corporation  are fair to the  shareholders  of Northern  Lehigh from a financial
point of view. See "APPROVAL OF THE MERGER--Opinion of Financial Advisor."

The Board's Determination About the Merger

     While examining the  Harleysville  National  Corporation  proposal to merge
with Northern Lehigh, the Northern Lehigh Board of Directors determined that:


                                      -22-

<PAGE>

     *    the  Harleysville  National  Corporation  operating  culture  would be
          consistent  and  helpful  to the  continued  growth  of  The  Citizens
          National Bank of Slatington's community banking opportunities;

     *    the respective business management philosophies of Northern Lehigh and
          Harleysville National Corporation were compatible;

     *    the  Harleysville  National  Corporation  branch  bank  locations  and
          employment  opportunities,  due to the lack of  necessity  for  branch
          consolidation  and lack of  substantial  administrative  job  overlap,
          would  be  very   attractive   for  The  Citizens   National  Bank  of
          Slatington's employees;

     *    the  significant   additional  resources  that  Harleysville  National
          Corporation  would bring to face the  competitive  environment  in the
          financial  markets  currently served by The Citizens  National Bank of
          Slatington  would  generally  be  beneficial  to the  Northern  Lehigh
          customers, staff and community;

     *    Harleysville  National  Corporation  could provide more  comprehensive
          financial  services to the markets  currently  served by The  Citizens
          National Bank of Slatington;

     *    projected social and economic benefits would accrue to Northern Lehigh
          its  shareholders  and  other  corporate   constituencies,   including
          employees,  suppliers  and  customers  in  the  communities  in  which
          Northern Lehigh does business; and

     *    the terms of the proposed  merger  compare  favorably to the financial
          terms of other recent  business  combinations  in the local  financial
          services industry.

     In  addition,  the  Northern  Lehigh  Board of  Directors  determined  that
Harleysville National Corporation had a history of successful  acquisitions,  an
operating  culture that is similar to Northern  Lehigh's  and that  Harleysville
National  Corporation's  subsidiaries,  branches  and  business  operations  are
located in a geographic area of significant potential growth.

     In evaluating the proposed merger,  the Northern Lehigh Board of Directors,
from the  Northern  Lehigh's  shareholders'  viewpoint,  considered a variety of
financial factors, including:

     *    the consideration  being offered to Northern Lehigh's  shareholders in
          relation  to  the  market  value,  book  value,  earnings  per  share,
          projected   earnings  per  share  of  Northern  Lehigh  and  projected
          increased dividends;
      
     *    that  the   consideration   to  be  received   by  Northern   Lehigh's
          shareholders  reflects  a premium  over the  values at which  Northern
          Lehigh common stock has traded in the market;

     *    the  quality  of a  financial  investment  in  and  the  liquidity  of
          Harleysville National Corporation common stock; and

     *    the current  operations,  financial  condition and future prospects of
          Harleysville National Corporation and Northern Lehigh.

     In examining whether to enter into the merger,  the Board of Directors also
considered,  among other things,  the financial  terms of the  transaction,  the
structure  of  the  transaction,  the  historic  and  financial  performance  of
Harleysville National Corporation , the commitment of

                                      -23-

<PAGE>

Harleysville National Corporation to the communities its subsidiaries serve, the
culture of  Harleysville  National  Corporation,  and the  opinion  of  Northern
Lehigh's  investment  banker  as to  the  fairness  of the  transaction,  from a
financial point of view, to Northern Lehigh's shareholders.

     In addition to the  benefits  outlined  above,  the Board of  Directors  of
Northern Lehigh also determined that Harleysville  National Corporation would be
an attractive partner for certain additional reasons. The transaction would:

     *    provide Northern Lehigh with additional management and support systems
          that will better enable Northern Lehigh to adapt its operations to the
          rapidly changing legal and competitive  conditions  within the banking
          industry;

     *    permit  Harleysville  National  Corporation  to  share  with  Northern
          Lehigh,  a strong  commitment  to the  concept  of  community-oriented
          banking; and

     *    will enable  Northern  Lehigh's  banking offices to offer customers an
          expanded range of products and services.

     For example,  following the merger,  Northern Lehigh's offices will be able
to provide new and expanded  banking services to its customers that are provided
currently by The Citizens National Bank of Lansford.  The Citizens National Bank
of Lansford  has offered  some  innovative  products to its  marketplace.  These
products can be easily transferred and implemented,  with some modifications for
competitive pricing, into Northern Lehigh's marketplace.

     One such  product is called Kids  Banking.  This  program  concentrates  on
educating  youth in the  workings of the  economic  system,  how banks  interact
within the  economy,  how to apply for  credit,  how to write  checks and how to
budget.  The program  attempts to involve  local schools  providing  educational
materials to teachers to promote a better understanding of banking for students.

     Another  program  offered by The Citizens  National  Bank of Lansford  that
would  benefit  Northern  Lehigh's  marketplace  is its "Seniors  Program."  The
program  requires  a deposit  relationship  of  minimum  proportions  and offers
selected  free banking  services to seniors,  along with social  activities  and
educational opportunities.

     In addition,  the "Choice Cash" line of credit is another product that will
be of great  benefit to  Northern  Lehigh's  market.  This line of credit can be
linked to a checking account  affording  customers the convenience of worry free
overdraft  protection.  No overdraft  fees are incurred when using this product.
The customer makes a monthly  payment on his or her line or pays the outstanding
balance, in full, at any time.

     The Citizens National Bank of Slatington branches will also offer a 30-year
fixed rate mortgage product. Unlike the 3-5 year demand notes, the 30-year fixed
rate mortgage  provides the  opportunity to lock in a competitive  interest rate
that  remains  the same  over the  entire  term of the  mortgage.  This  will be
advantageous to the many consumers in The Citizens National Bank

                                      -24-

<PAGE>

of Slatington's  market area who plan to remain in their homes for an indefinite
period and who desire a fixed monthly payment.

     The Citizens National Bank of Lansford has a wide range of deposit and loan
products that could accommodate  Northern Lehigh's  customers'  borrowing needs.
Lending  could be  expanded  in  Northern  Lehigh's  marketplace  by adding more
competitive  and  additional   products  that  will  benefit  Northern  Lehigh's
community and its citizens. The Citizens National Bank of Lansford's experienced
management  and greater  financial  resources are expected to provide a benefit.
For example, Northern Lehigh will be able to entertain more small to medium size
business  loans.  Thus,  the  transaction  will  enhance the ability of Northern
Lehigh's offices to remain competitive and to satisfy their customers' financial
needs.

     The proposed transaction will benefit Harleysville  National Corporation by
strengthening  its  market  presence  in Lehigh  County,  Pennsylvania,  thereby
improving its ability to compete in that region.

     Northern   Lehigh's  Board  of  Directors   believes  the  proposed  merger
represents  an  attractive  opportunity  to  acquire  access  to the  additional
managerial expertise and specialized  services offered by Harleysville  National
Corporation and its banking subsidiary,  The Citizens National Bank of Lansford.
This will permit Northern Lehigh's banking offices to provide a broader range of
services to their  customers in the face of increasing  competition  from larger
financial institutions.

     As we discuss in "Management and Operations Following the Merger," Northern
Lehigh's  offices will continue to employ and be administered  by  knowledgeable
local residents for the benefit of the local community.

     In light of the  careful  analysis  by the Board,  and with the  assistance
during the negotiations of Hopper Soliday,  its investment  banker, the Northern
Lehigh Board was able to negotiate the agreement to help assure that:

     *    the  value  and  liquidity  of  the  Northern   Lehigh   shareholders'
          investment will increase;

     *    The Citizens National Bank of Slatington will continue to have a local
          identity in Slatington;

     *    the current  employees of The Citizens  National Bank of  Slatington's
          may continue their employment;

     *    the service of Northern Lehigh's  directors will continue for the near
          future;

     *    the structure of The Citizens  National Bank of  Slatington's  banking
          offices, after the merger, will provide advantageous financial service
          to the community and to the customers of The Citizens National Bank of
          Slatington; and

     *    new products and services will be available to customers.

                                      -25-

<PAGE>

For example,  after the merger, trust services will be available to The Citizens
National  Bank of  Slatington's  customers,  and the merger will lead to greater
financial  resources  to serve  the  lending  and  deposit  needs  of the  local
communities presently served by Northern Lehigh.

     Northern  Lehigh's  Board  believes that the surviving  bank can expand its
resources and its range of products and services on an accelerated  timetable as
compared to The Citizens  National Bank of  Slatington  when relying on internal
growth. In general,  Northern Lehigh is entering into the transaction because it
believes it can better maximize its  shareholders'  long-term  return through an
affiliation with a larger,  more diversified  community  financial  institution.
Northern  Lehigh's  Board  of  Directors  believed  that  Harleysville  National
Corporation's  greater  resources  would  enable The Citizens  National  Bank of
Slatington to offer  expanded  services to its customers and the  communities it
serves.  In addition,  the transaction with  Harleysville  National  Corporation
would increase the liquidity of the stock held by Northern Lehigh's shareholders
by exchanging it for stock in a larger banking  organization  that is quoted and
traded on the Nasdaq National Market System.

     In  summary,  the primary  reasons  that the Board has agreed to the merger
with Northern  Lehigh is that, as outlined  above,  in the opinion of the Board,
the merger provides a fair financial  return to Northern  Lehigh's  shareholders
and  increases  the  liquidity of their stock while  maintaining,  to the extent
possible,  the local  identity for The Citizens  National  Bank of Slatington to
serve the community,  and The Citizens National Bank of Slatington's  customers,
employees and other  constituencies.  The Board  concluded  that the merger will
better  permit  in a  rapidly  changing,  increasingly  competitive  market  for
financial  services,  Northern Lehigh to compete more effectively as a part of a
larger  banking  organization  with more resources and a wider range of products
and  services  than  those  that  Northern  Lehigh  currently  offers  or in the
immediate future could offer, and that Harleysville  National  Corporation had a
community banking  orientation,  continued the name recognition of "The Citizens
National Bank" and a continued  presence in the local banking market of Northern
Lehigh.

Additional Reasons for the Merger

     In addition to the  considerations  related directly to the merger,  recent
changes in  federal  and state  banking  laws and  regulations  have had a major
impact  upon the banking  industry in  Pennsylvania  and  throughout  the United
States. Recent changes in federal banking laws have significantly  increased the
severity and complexity of federal banking  regulations as well as the costs the
banks must incur in  complying  with those  regulations.  In  response  to these
changes,  many  mergers  and  consolidations  involving  banks and bank  holding
companies have occurred to provide the capital and depth of management necessary
to comply with the numerous  complex  laws and  regulations  applicable  to bank
holding  companies.  Further  merger  activity is likely to occur in the future,
resulting  in  increased  concentration  levels  in  banking  markets  and other
significant changes in the competitive  environment.  These changes are expected
to intensify competition in local and regional banking markets.

     The   factors    discussed    above   and    elsewhere    in   this   proxy
statement/prospectus  are believed to all of the material factors  considered by
the Northern Lehigh Board of Directors in evaluating the transaction. In view of
the  wide  variety  of  material  factors  considered  in  connection  with  its
evaluation  of the  transaction,  the  Northern  Lehigh  Board  did not  find it
practical to, and did not,  quantify or otherwise attempt to assign any relative
weight to the various factors considered,  except,  however,  that liquidity and
the size and attributes of Harleysville  National Corporation were determined by
the Board to be significant  factors.  In addition,  individual  Northern Lehigh
directors may have given differing weights to different factors. There can be no
assurance that any of the potential  opportunities  considered by the Board will
be achieved through consummation of the transaction.

     As stated above, Hopper Soliday has advised the Board of Directors that the
terms  of the  agreement  are  fair to  Northern  Lehigh's  shareholders  from a
financial point of view. As noted above,  the Northern Lehigh Board of Directors
expects that the proposed  transaction will benefit the shareholders of Northern
Lehigh by  providing  them with equity  ownership  in a larger,  publicly-traded
banking organization and, thereby, increasing the liquidity of their investment.
Historically, Northern Lehigh common stock has been traded on a 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.  After the merger,
the  shareholders  of  Northern  Lehigh  will  receive   Harleysville   National
Corporation common stock that is more actively traded on the Nasdaq market.

     For the reasons set forth above in this section and elsewhere in this proxy
statement/prospectus,  the Northern  Lehigh Board of Directors  had  unanimously
concluded  that the proposed  transaction  is in the best  interests of Northern
Lehigh's shareholders, employees, customers and community.

Opinion of Financial Advisor

     General

     The Northern  Lehigh Board of Directors  engaged  Hopper Soliday to provide
financial  advisory and investment  banking  services to Northern Lehigh and its
sole  subsidiary,  The  Citizens  National  Bank of  Slatington,  regarding  the
possible sale of Northern Lehigh to Harleysville National Corporation. The terms
of the  engagement  were  contained in a letter dated  October 10, 1997. In this
section of the proxy  statement/prospectus,  Northern  Lehigh  and The  Citizens
National Bank of Slatington  are referred to together as Northern  Lehigh.  From
time to time during the past ten years Hopper  Soliday has  provided  investment
banking  services to Northern  Lehigh.  For these  services,  Hopper Soliday has
received normal and customary compensation.  Other than this transaction, Hopper
Soliday  currently has no other material  relationship  with Northern  Lehigh or
Harleysville National Corporation.

     Hopper Soliday is a regional  investment  banking firm. As a customary part
of its investment  banking  business  Hopper Soliday engages in the valuation of
bank  and  bank  holding   company   securities  in  connection   with  mergers,
acquisitions, underwritings, secondary

                                      -27-

<PAGE>
distributions  of  listed  and  unlisted  securities,   private  placements  and
valuations for various other purposes.  As an investment  banking  specialist in
the securities of financial institutions,  Hopper Soliday has experience in, and
knowledge  of, the valuation of banking  companies  like  Northern  Lehigh.  The
Northern Lehigh Board selected Hopper Soliday on the basis of Hopper Soliday's:

     *    ability to evaluate the fairness of the merger to the  shareholders of
          Northern Lehigh from a financial point of view;

     *    qualifications;

     *    previous experience; and

     *    reputation in the banking and investment communities.

Hopper Soliday has acted  exclusively for the Northern Lehigh Board in providing
its  fairness  opinion  and will  receive  a fee from  Northern  Lehigh  for its
services.

     Hopper  Soliday has given a written  opinion to the Northern  Lehigh Board,
dated July 28, 1998, and confirmed by an updated written opinion to the Northern
Lehigh Board,  dated November 12, 1998, that the consideration to be received in
the merger is fair,  from a  financial  point of view,  to the  shareholders  of
Northern Lehigh.  The full text of the updated opinion is attached as Annex B to
this proxy statement/prospectus.  Northern Lehigh shareholders are urged to read
the Hopper  Soliday  opinion in its entirety for a description of the procedures
followed,   assumptions  made,  matters   considered,   and  qualifications  and
limitations on the review undertaken by Hopper Soliday in rendering its opinion.
The  following  discussion  of the  opinion is  qualified  by the  opinion.  The
consideration to be received in the merger was determined by negotiation between
Northern  Lehigh,  represented  by Hopper  Soliday,  and  Harleysville  National
Corporation.  The  consideration to be received in the merger was not determined
by Hopper  Soliday.  See  "APPROVAL  OF THE  MERGER--Background  of the  Merger,
Reasons and Recommendation of the Board of Directors."

     The Hopper Soliday opinion only addresses the  consideration to be received
in  the  merger  by the  Northern  Lehigh  shareholders.  The  opinion  is not a
recommendation  to any Northern  Lehigh  shareholder  as to how the  shareholder
should vote at the meeting.

     In giving its opinion dated July 28, 1998, Hopper Soliday  reviewed,  among
other  things:

     *    Northern Lehigh's Annual Reports and related financial information for
          years ended December 31, 1993, through December 31, 1997, and Northern
          Lehigh's  Quarterly FDIC Call Report and related  unaudited  financial
          information for the period ending March 31, 1998;

     *    Harleysville  National  Corporation's  Annual Reports on Form 10-K and
          related  financial  information  for years ended  December  31,  1993,
          through  December 31, 1997, and Quarterly  Report on Form 10-Q for the
          period ended March 31, 1998;

     *    certain information concerning the respective businesses,  operations,
          regulatory   condition   and   prospects  of   Harleysville   National
          Corporation  and  Northern  Lehigh,   including  financial  forecasts,
          relating to the business, earnings, assets and

                                      -28-

<PAGE>

          prospects of Harleysville  National  Corporation and Northern  Lehigh,
          furnished to Hopper Soliday by Harleysville  National  Corporation and
          Northern Lehigh, which Hopper Soliday discussed with members of senior
          management of Harleysville National Corporation and Northern Lehigh;

     *    historical  market  prices and trading  activity for the  Harleysville
          National Corporation common stock and Northern Lehigh common stock and
          similar  data for  certain  publicly  traded  companies  which  Hopper
          Soliday deemed to be relevant;

     *    the results of operations of  Harleysville  National  Corporation  and
          Northern  Lehigh and similar data for certain  companies  which Hopper
          Soliday deemed to be relevant;

     *    the financial  terms  contained in the agreement that provides for the
          merger  and  the   financial   terms  of  certain  other  mergers  and
          acquisitions which Hopper Soliday 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 National Corporation;

     *    the  agreement  that  provides  for the merger and the exhibits to the
          agreement;   and

     *    such other matters as Hopper Soliday deemed necessary.

Hopper  Soliday also met with  certain  members of senior  management  and other
representatives  of  Harleysville  National  Corporation  and Northern Lehigh to
discuss the items  mentioned  above and the details of the  transaction.  Hopper
Soliday  also  considered  financial  and other  factors  that it believed  were
important under the circumstances and took into account its:

     *    assessment of general economic, market and financial conditions;
      
     *    experience in similar transactions; and

     *    experience  in  securities  valuation and its knowledge of the banking
          industry generally.

     In giving its updated  written  opinion  dated  November 12,  1998,  Hopper
Soliday  confirmed the  appropriateness  of its reliance on the analyses used to
give its July 28, 1998 written opinion.  This was done by performing  procedures
to update  certain of the analyses and by reviewing the  assumptions  upon which
the analyses were based and the factors considered.  Hopper Soliday's opinion is
based upon  conditions as they existed and could be evaluated on the  respective
evaluation  on July 28, 1998,  and November 12, 1998.  The opinion is also based
upon the information made available to Hopper Soliday through those dates.

     Hopper Soliday 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 Hopper  Soliday in rendering its opinion,  Hopper Soliday
assumed  that  the  financial   forecasts  were  reasonably  prepared  on  bases
reflecting the best currently available estimates and judgments of the

                                      -29-

<PAGE>

managements of Northern Lehigh and Harleysville  National  Corporation as to the
future  financial  performance  of  Northern  Lehigh and  Harleysville  National
Corporation.   Hopper  Soliday  did  not  make  any  independent  evaluation  or
appraisals of the assets or liabilities of Harleysville National Corporation nor
was it furnished with any such appraisals.

     The  discussion  below is not intended to be a complete  description of the
analyses performed by Hopper Soliday in giving its opinion. 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.  Therefore, an opinion is not easily summarized or
discussed. Despite the separate factors disclosed below, Hopper Soliday believes
that its analyses must be considered as a whole.  Hopper  Soliday  believes 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 its opinion.  No one of the analyses performed by
Hopper  Soliday was  assigned a greater  significance  with  respect to industry
performance,  business and economic conditions and other matters,  many of which
are beyond Northern Lehigh's or Harleysville National Corporation's control. The
analyses  performed by Hopper Soliday are not  necessarily  indicative of actual
values or future results.  Results may be  significantly  more or less favorable
than suggested by the analyses. Additionally, analyses relating to the values of
businesses are not  appraisals.  These analyses do not  necessarily  reflect the
prices at which businesses actually may be sold.

     Transaction Summary

     Hopper Soliday reviewed the key financial terms of the proposed merger with
the Northern  Lehigh Board,  including the expected method of accounting and tax
treatment of the Northern Lehigh  shareholders,  the exchange  ratio,  the share
price of Harleysville  National  Corporation  common stock, as of July 24, 1998,
the resulting  indicated  value per share of Northern Lehigh common stock in the
merger and the resulting  indicated  aggregate  consideration  to be paid in the
merger, as follows:


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

     *    The  indicated  value was $151.70 per share of Northern  Lehigh common
          stock,  determined by  multiplying  the exchange  ratio by the closing
          price on the Nasdaq/NMS of Harleysville  National  Corporation  common
          stock on July 24, 1998; and

     *    The  indicated  aggregate  consideration  to be paid in the merger was
          $21.1 million based on 139,498 fully diluted shares of Northern Lehigh
          common stock outstanding.

Hopper Soliday noted that:

     *    the  value  of  the   consideration  to  be  received  in  the  merger
          represented a 163% premium to Northern Lehigh's market price of $57.75
          per  share  on July  24,  1998;  and

     *    the  $151.70  per share value  represented  257% of Northern  Lehigh's
          fully-diluted  book value per share as of June 30, 1998, a multiple of
          22.04 times  Northern  Lehigh's net income for the twelve months ended
          June 30, 1998 and a premium  over  tangible  book to core  deposits of
          21.6% as of March 31, 1998.

     Contribution Analysis

     Hopper Soliday  reviewed the  contribution  made by each of Northern Lehigh
and  Harleysville  National  Corporation to various  balance sheet items and net
income of the combined  company at the proposed  exchange ratio based on balance
sheet data at March 31, 1998,  and trailing  twelve months  earnings as of March
31, 1998. This analysis showed that:

     *    Northern  Lehigh  shareholders  would  own  approximately  6.8% of the
          aggregate shares outstanding of the combined company; and
      
     *    Northern Lehigh was contributing  5.8% of total assets,  7.2% of total
          loans, 6.2% of total deposits,  6.6% of shareholders'  equity and 5.2%
          of net income,  respectively,  of the pro forma combined company as of
          March 31, 1998.

     Summary Comparison of Northern Lehigh,  Harleysville  National  Corporation
and Peer Groups

     Hopper  Soliday  compared  selected  balance  sheet  data,  asset  quality,
capitalization  and  profitability  ratios and market statistics using financial
data at or for the twelve months ended March 31, 1998 and market data as of July
24,  1998 for  Northern  Lehigh to a peer group of  Pennsylvania  banks and bank
holding companies  consisting of ten institutions each with total assets between
$55 million and $145 million and for Harleysville National Corporation to a peer
group of  Pennsylvania  banks and bank  holding  companies  consisting  of seven
institutions  each with total assets between $550 million and $1.3 billion.  The
analysis included the following ratios:

     Summary of Selected Bank Merger and Acquisition Transactions

     Hopper Soliday compared the ratios of price/book,  price/trailing 12 months
earnings,  book/book  and tangible book  premium/core  deposits for the proposed
merger to the mean and median ratios for a group of ten  transactions  announced
since January 1, 1996.  The selected  transactions  involved the  acquisition of
banks and bank holding companies headquartered in Pennsylvania with total assets
less than $500 million and announced transaction values between $4.6 million and
$137.8  million.  This  analysis  showed  that the  merger  consideration  to be
received represented:

     *    257.0% of Northern Lehigh's  fully-diluted  book value versus a median
          of 255.1% for the selected transactions;

     *    a  price/trailing  12 months  earnings  ratio of 22.0x  compared  to a
          median of 24.7x for the selected transactions;

     *    a  book/book  of 100.0%  compared  to a median  of 95.6% for  selected
          transactions; and

     *    a tangible book  premium/core  deposits  ratio of 21.6%  compared to a
          median of 21.6% for the selected transactions.

     No  company  or  transaction  used  as a  comparison  in this  analysis  is
identical to Northern Lehigh,  Harleysville National Corporation or the proposed
merger  transaction.  The  analysis  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 were  compared.  The
ranges of valuations  resulting from any  particular  analysis  described  above
should not be taken to be Hopper  Soliday's view of the actual value of Northern
Lehigh or Harleysville National

                                      -32-
<PAGE>
Corporation.  The fact that any specific  analysis has been  referred to in this
discussion is not meant to indicate that the analysis was given more weight than
any other analyses.

     In performing its analyses, Hopper Soliday made numerous assumptions. These
assumptions included:

          *    industry performance;

          *    general business and economic conditions; and

          *    other matters.

Many of  these  assumptions  are  beyond  the  control  of  Northern  Lehigh  or
Harleysville National Corporation.  The analyses performed by Hopper Soliday are
not  necessarily  indicative of actual values or actual  future  results.  These
results  may be  significantly  more or less  favorable  than  suggested  by the
analyses.  The  analyses  are not  appraisals.  The  analyses do not 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, the opinion and the presentation to the Northern
Lehigh  Board  is just  one of many  factors  taken  into  consideration  by the
Northern Lehigh Board.

     Pursuant to the Hopper Soliday engagement letter, Northern Lehigh agreed to
pay Hopper Soliday a fee of 1.00% of the aggregate  consideration  to be paid in
the merger. This fee is contingent upon completion of the merger. Hopper Soliday
will also be reimbursed for reasonable out-of-pocket expenses incurred on behalf
of Northern  Lehigh.  Northern  Lehigh has agreed to indemnify and hold harmless
Hopper Soliday from and against certain  liabilities under United States federal
securities laws in connection with this engagement.

Dissenters' Rights

General

     Pursuant to the  Pennsylvania  Business  Corporation Law of 1988, you, as a
shareholder of Northern Lehigh common stock,  have the right to dissent from the
merger and to obtain  payment of the "fair value" of your shares in the event we
complete the merger.

     If you contemplate  exercising  your right to dissent,  we urge you to read
carefully  the  provisions  of  Subchapter  D of Chapter 15 of the  Pennsylvania
Business   Corporation   Law  of  1988,   which  is   attached   to  this  proxy
statement/prospectus  as Annex C. A discussion of the  provisions of the statute
is included here.  The discussion  describes the steps that you must take if you
want to  exercise  your right to dissent.  You should read this  summary and the
full text of the law.

     Before the day of the merger,  send any written notice or demand,  required
concerning  your exercise of dissenters'  rights to Francis P.  Burbidge,  First
Vice  President,  Northern Lehigh  Bancorp,  Inc., 502 Main Street,  Slatington,
Pennsylvania 18080-0008. After the day of the

                                      -33-

<PAGE>

merger, send correspondence to Jo Ann Bynon,  Corporate Secretary,  Harleysville
National Corporation, 483 Main Street, Harleysville, Pennsylvania 19438.

Fair Value

     The term "fair value" means the value of a share of Northern  Lehigh common
stock  immediately  before day of the merger  taking into  account all  relevant
factors,  but excluding any  appreciation or depreciation in anticipation of the
merger.

Notice of Intention to Dissent

     If you wish to dissent, you must:

     *    file a written notice of intention to demand payment of the fair value
          of your  shares  of  Northern  Lehigh  common  stock if the  merger is
          effected with Northern  Lehigh,  prior to the vote of  shareholders on
          the merger at the meeting;

     *    make no change in your beneficial  ownership of Northern Lehigh common
          stock from the date you give notice through the day of the merger; and

     *    not vote  your  Northern  Lehigh  common  stock  for  approval  of the
          agreement.

Neither a proxy  nor a vote  against  approval  of the  merger is the  necessary
written notice of intention to dissent.

     Notice to Demand Payment

     If the merger is approved by the required  vote of  shareholders,  Northern
Lehigh or  Harleysville  National  Corporation,  as the case may be, will mail a
notice to all  dissenters who gave due notice of intention to demand payment and
who did not vote for approval of the agreement.  The notice will state where and
when you must  deliver a written  demand for payment and where you must  deposit
certificates  for Northern Lehigh common stock in order to obtain  payment.  The
notice will include a form for demanding payment and a copy of the law. The time
set for receipt of the demand for payment and deposit of stock certificates will
be not less than 30 days from the date of mailing of the notice.

     Failure to Comply with Notice to Demand Payment, etc.

     You must  take each step in the  indicated  order and in strict  compliance
with the  statute  to keep your  dissenters'  rights.  If you fail to follow the
steps,  you will lose you right to dissent and you will  receive  3.57 shares of
Harleysville National Corporation stock.

     Payment of Fair Value of Shares

     Promptly after the merger,  or upon timely receipt of demand for payment if
the merger already has taken place,  Harleysville National Corporation will send
dissenters, who have

                                      -34-

<PAGE>

deposited  their  stock  certificates,  the amount  that  Harleysville  National
Corporation  estimates to be the fair value of the Northern Lehigh common stock.
The remittance or notice will be accompanied by:

     *    a closing balance sheet and statement of income of Northern Lehigh for
          a fiscal  year  ending  not more  than 16  months  before  the date of
          remittance  or  notice  together  with the  latest  available  interim
          financial statements;

     *    a statement of  Harleysville  National  Corporation's  estimate of the
          fair value of the Northern Lehigh common stock; and

     *    a notice of the right of the dissenter to demand supplemental payment,
          accompanied by a copy of the law.

     Estimate by Dissenter of Fair Value of Shares

     If a dissenter  believes that the amount stated or remitted by Harleysville
National  Corporation is less than the fair value of the Northern  Lehigh common
stock,  the  dissenter  may send an estimate  of the fair value of the  Northern
Lehigh  common  stock to  Harleysville  National  Corporation.  If  Harleysville
National Corporation remits payment of estimated value of a dissenter's Northern
Lehigh  common  stock and the  dissenter  does not file his or her own  estimate
within 30 days after the mailing by  Harleysville  National  Corporation  of its
remittance,  the dissenter will be entitled to no more than the amount  remitted
by Harleysville National Corporation.

     Valuation Proceedings

     If any demands for payment remain unsettled within 60 days after the latest
to occur of:

     *    the merger;
      
     *    timely   receipt  by   Northern   Lehigh  or   Harleysville   National
          Corporation, as the case may be, of any demands for payment; or

     *    timely   receipt  by   Northern   Lehigh  or   Harleysville   National
          Corporation, as the case may be, of any estimates by dissenters of the
          fair value,

then, Harleysville National Corporation may file an application, in the Court of
Common Pleas of Lehigh  County,  requesting  that the court  determine  the fair
value of the Northern Lehigh common stock. If this happens,  all dissenters,  no
matter where they reside,  whose  demands have not been  settled,  shall be made
parties  to the  proceeding.  In  addition,  a copy of the  application  will be
delivered to each dissenter.

     If  Harleysville   National  Corporation  were  to  fail  to  file  the  an
application,  then any  dissenter,  on behalf of all  dissenters who have made a
demand  and who have not  settled  their  claim  against  Harleysville  National
Corporation,  may  file an  application  in the  name of  Harleysville  National
Corporation  at any time within the 30-day  period after the  expiration  of the
60-day period and request that the Lehigh County Court  determine the fair value
of the shares.

                                      -35-

<PAGE>

The fair value  determined by the Lehigh  County Court may, but need not,  equal
the  dissenters'  estimates of fair value. If no dissenter files an application,
then  each  dissenter  entitled  to do so  shall be paid  Harleysville  National
Corporation's  estimates of the fair value of the Northern  Lehigh  common stock
and no more,  and may bring an action  to  recover  any  amount  not  previously
remitted,  plus  interest  at a rate the  Lehigh  County  Court  finds  fair and
equitable.

     Harleysville  National  Corporation intends to negotiate in good faith with
any dissenting shareholders.  If, after negotiation,  a claim cannot be settled,
then Harleysville National Corporation intends to file an application requesting
that the fair value of the Northern  Lehigh  common stock be  determined  by the
Lehigh County Court.

     Costs and Expenses

     The costs and expenses of any  valuation  proceedings  in the Lehigh County
Court,  including  the  reasonable  compensation  and expenses of any  appraiser
appointed by the Court to recommend a decision on the issue of fair value,  will
be  determined  by  the  Court  and  assessed  against   Harleysville   National
Corporation  except that any part of the costs and expenses  may be  apportioned
and assessed by the Court against all or any of the  dissenters  who are parties
and whose  action  in  demanding  supplemental  payment  the  Court  finds to be
dilatory, obdurate, arbitrary, vexatious or in bad faith.

Terms of the Merger

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

     Effect of the Merger

     Northern Lehigh will merge into Harleysville  National  Corporation  North.
Harleysville  National Corporation North will be the surviving corporation under
the name  "Harleysville  National  Corporation North, Inc." Northern Lehigh will
cease to exist. Immediately thereafter, The Citizens National Bank of Slatington
will merge into The Citizens  National Bank of Lansford under the name "Citizens
National Bank." The Citizens National Bank of Slatington will cease to exist.

     Exchange of Shares

     On the day of the merger,  each outstanding share of Northern Lehigh common
stock will  become the right to receive  3.57  shares of  Harleysville  National
Corporation  common stock,  subject to adjustment  for certain stock  dividends,
stock splits and similar transactions.


                                      -36-

<PAGE>
     Harleysville  National  Corporation  will not  issue  fractional  shares of
Harleysville  National  Corporation  common  stock in the  merger.  Each  former
shareholder of Northern  Lehigh will receive cash in an amount equal to the fair
market value of any fractional share interest.

     Harleysville  National  Corporation and Northern Lehigh anticipate that the
merger will occur during the first quarter of 1999, 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 June 30, 1999,
and the parties have not agreed otherwise prior to that date, the agreement will
terminate   automatically.   See,  "Business  Pending  the   Merger--Conditions,
Amendment  and   Termination"for   a  discussion  of  the  various   termination
provisions.

     Following  the  merger,  former  shareholders  of  Northern  Lehigh will be
required to  surrender  their  Northern  Lehigh  common  stock  certificates  to
Harleysville   National  Corporation.   Detailed  instructions   concerning  the
procedure for surrendering the Northern Lehigh common stock certificates will be
sent by Harleysville National Corporation to each former shareholder of Northern
Lehigh  on or  promptly  after  the  merger.  Upon  proper  surrender  of  stock
certificates,  each former shareholder of Northern Lehigh will be issued a stock
certificate  representing  the number of whole shares of  Harleysville  National
Corporation  common stock into which his or her shares of Northern Lehigh common
stock were converted.  Each  shareholder will also receive a check in the amount
of any  cash to which  he or she is  entitled  instead  of a  fractional  share.
Shareholders  of Northern  Lehigh should not  surrender  their  Northern  Lehigh
common stock  certificates for exchange until they receive written  instructions
to do so from Harleysville National Corporation.

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

     All Northern Lehigh stock  certificates must be surrendered to Harleysville
National  Corporation  within two years after the merger.  In the event that any
former  shareholder  of Northern  Lehigh does not properly  surrender his or her
Northern  Lehigh  certificates  within  that time,  the  shares of  Harleysville
National  Corporation common stock that would otherwise have been issued may, at
the option of Harleysville National Corporation, be sold and the net proceeds of
the sale,  together with the cash (if any) to which the  stockholder is entitled
instead of the issuance of a  fractional  share and any  previously  accrued and
unpaid dividends,  will be held in a non-interest bearing account for his or her
benefit.  After the sale,  the sole right of the former  shareholder of Northern
Lehigh will be the right to collect the net proceeds, cash and

                                      -37-

<PAGE>

accumulated  dividends.  Subject to laws of escheat, the net proceeds,  cash and
accumulated dividends will be paid to the former shareholder of Northern Lehigh,
without  interest,  upon proper  surrender of his or her Northern  Lehigh common
stock certificates.

     Stock Options

     As part of the transaction, 5,000 outstanding options to purchase shares of
Northern Lehigh common stock issued by Northern Lehigh will be converted, on the
day of the merger,  into the right to receive  options to acquire 17,850 shares,
the number of shares of Harleysville  National Corporation common stock equal to
the  number of shares of  Northern  Lehigh  common  stock  covered by the option
multiplied  by 3.57,  and the exercise  price for a whole share of  Harleysville
National  Corporation  common stock shall be the stated  exercise price for such
option divided by 3.57. The shares issuable upon exercise of the options will be
issued in  accordance  with the terms of the  respective  option  agreements  of
Northern  Lehigh under which they were  originally  issued.  See,  "Terms of the
Merger and -- Accounting Treatment."

Business Pending the Merger

     Northern  Lehigh  agreed to conduct its business in the usual,  regular and
ordinary course, consistent with prudent business judgment,  pending the merger.
Northern  Lehigh has agreed to take action in the ordinary course of business or
get the prior written consent of  Harleysville  National  Corporation.  Northern
Lehigh and The Citizens  National  Bank of Slatington  agreed that,  among other
things, pending the merger, they will:

     *    not amend their Articles of Incorporation or Bylaws;

     *    not  declare,  set  aside  or pay  any  dividend  or  make  any  other
          distribution in respect of Northern  Lehigh and The Citizens  National
          Bank of Slatington common stock,  except as provided in Section 4.9 of
          the agreement;

     *    not authorize,  purchase, issue or sell (or authorize,  issue or grant
          options,  warrants  or  rights  to  purchase  or sell)  any  shares of
          Northern Lehigh common stock or any other equity or debt securities of
          Northern  Lehigh or any securities  convertible  into Northern  Lehigh
          common stock;

     *    not change the  presently  outstanding  number of shares or effect any
          capitalization, reclassification, stock dividends, 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 benefit,  incentive or welfare contract,  or plan or
          arrangement, or any trust agreement related thereto, in respect to any
          of their directors, officers, or other employees;

     *    not make any loan or other  credit  facility  commitment  in excess of
          $100,000 (including without limitation, lines of credit and letters of
          credit) to any affiliate or  compromise,  expand,  renew or modify any
          such outstanding commitment;

                                      -38-

<PAGE>

     *    not  enter  into  any  swap  or  similar   commitment,   agreement  or
          arrangement  which is not  consistent  with  past  practice  and which
          increases the credit or interest rate risk over the levels existing at
          December 31, 1997; 

     *    not enter into any  derivative,  cap or floor or  similar  commitment,
          agreement or  arrangement,  except in the ordinary  course of business
          and consistent with past practices;

     *    not  enter  into  any  participation   arrangements  or  approvals  of
          extensions  of  credit in excess  of  $350,000,  expand or modify  any
          outstanding participation arrangements or approvals; and

     *    not sell,  exchange or otherwise dispose of any investment  securities
          or loans that are held for sale, prior to scheduled maturity and other
          than  pursuant  to  policies  agreed  upon  from  time  to time by the
          parties.

     There  have  been no  material  contracts  or  other  transactions  between
Northern  Lehigh  and  Harleysville   National  Corporation  since  signing  the
agreement,   nor  have  there  been  any   material   contracts,   arrangements,
relationships or transactions between Northern Lehigh and Harleysville  National
Corporation  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 National Corporation and Northern Lehigh 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 Northern Lehigh;
      
     *    approval by the Board of Governors of the Federal Reserve System,  the
          Office  of  the  Comptroller  of the  Currency  and  the  Pennsylvania

     *    continued  effectiveness of the registration  statement containing the

          interests for financial reporting purposes;

     *   determination  of  compliance  with all  applicable  federal and state
          securities and anti-trust laws; and

     *    exercise by dissenting shareholders of dissenters' rights with respect
          to less than 6,975 shares of Northern Lehigh common stock.

     In  connection  with  the  regulatory   approvals,   Harleysville  National
Corporation filed:

     *    a Notice with respect to the merger with the Board of Governors of the
          Federal Reserve System, on October 20, 1998; and

<PAGE>

     *    an  Application  with  the  Pennsylvania  Department  of  Banking,  on
          November 20, 1998.

In addition, on October 20, 1998, The Citizens National Bank of Lansford filed a
Business  Combination  Application  -  Streamlined,  requesting  approval of the
Office of the  Comptroller of the Currency to the merger of the banks.  We await
action on the applications  filed with the  Pennsylvania  Department of Banking.
The Board of  Governors  of the  Federal  Reserve  System  and the Office of the
Comptroller of the Currency have approved the transaction.

     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 Northern Lehigh's shareholders.  However,
no change in the amount of  consideration  to be received by the shareholders of
Northern  Lehigh  can be adopted  unless the  shareholders  of  Northern  Lehigh
approve the change.

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

     *    agreement of all of the parties;
      
     *    unilateral  action by each of the  parties  in the event of a material
          breach by any other party of any representation,  warranty or covenant
          not cured within  thirty (30) days or failure to satisfy any condition
          precedent to the  terminating  party's  obligation to  consummate  the
          merger through no fault of the terminating party; or

     *    automatically  in the event of a failure to  consummate  the merger by
          June 30, 1999, unless extended in writing prior that date.

Effective Date

     The agreement  provides that the closing of the transaction will occur at a
time and place, after three business days notice to Northern Lehigh, as shall be
agreed upon by the parties, but no later than the 30th business day after:

     *    the last approval of required governmental  authorities is granted and
          any related waiting periods expire;
      
     *    the  lifting,   discharge  or  dismissal  of  any  stay  of  any  such
          governmental approval or of any injunction against the merger; and

     *    all shareholder approvals required by the parties are received.

Immediately  following  the  closing,   provided  the  agreement  has  not  been
terminated or abandoned,  Northern Lehigh and Harleysville  National Corporation
North will cause Articles of Merger to be prepared, completed and filed with the
Secretary of State of the Commonwealth of  Pennsylvania.  The merger will become
effective  at 11:59 p.m.  on the day on which the  Articles  of Merger have been
duly filed with and accepted by the Pennsylvania Department of State.

                                      -40-

<PAGE>

     The bank merger  will  become  effective  on the day that  Northern  Lehigh
mergers into Harleysville  National Corporation North or the date upon which the
Office of the  Comptroller  of the Currency  issues a Certificate of Merger with
respect to the  merger of The  Citizens  National  Bank of  Slatington  into The
Citizens National Bank of Lansford.

     The agreement will automatically  terminate and the merger will be canceled
if all applicable  conditions  have not been satisfied by June 30, 1999,  unless
the parties have agreed prior to that date to extend the termination date of the
agreement.


Interests of Certain Persons in the Merger

     Certain  members of Northern  Lehigh's  management and the Northern  Lehigh
Board may have interests in the  transaction  in addition to their  interests as
shareholders of Northern Lehigh  generally.  These include,  among other things,
provisions in the agreement relating to indemnification and employment. You will
find  additional  information  about certain persons who may have an interest in
the  merger  in  the  following  section  entitled  "Management  and  Operations
Following the Merger." The Northern Lehigh 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 November 16, 1998,  the directors and executive  officers of Northern
Lehigh  and  The  Citizens   National  Bank  of  Slatington   beneficially   own
approximately  27,674 shares of Northern  Lehigh common stock,  including  5,000
stock options held by Mr. Burbidge.  On the day of the merger,  each option will
be assumed by Harleysville  National Corporation and shall be converted into and
become an option  to  acquire  that  number of shares of  Harleysville  National
Corporation common stock equal to the number of shares of Northern Lehigh common
stock covered by the option  multiplied  by 3.57, at an exercise  price equal to
the  present  stated  exercise  price of such  option  divided  by 3.57.  Shares
issuable  upon the exercise of these  options to acquire  Harleysville  National
Corporation  common stock shall be issuable in accordance  with the terms of the
respective agreements of Northern Lehigh under which they were issued.

     Pursuant to the agreement,  Harleysville National Corporation has agreed to
indemnify the present and former  officers,  directors,  employees and agents of
Northern  Lehigh and The Citizens  National Bank of Slatington  against  certain
liabilities  arising  prior to the  merger,  as  permitted  by the  Articles  of
Incorporation  and Bylaws of  Northern  Lehigh , the  charter  and bylaws of The
Citizens  National  Bank of  Slatington,  each as in  effect  on the date of the
agreement.

     In connection with the transaction,  Mr. Burbidge entered into an Executive
Employment  Agreement and a Consulting Agreement with The Citizens National Bank
of Lansford.  See "APPROVAL OF THE  MERGER--Management  and Operations Following
the  Merger,"  below,  for a  description  of  these  agreements  and  for  more
information  regarding  the  interests  of certain  persons in the matters to be
voted  upon.  Also see,  "APPROVAL  OF THE  MERGER--Terms  of the  Merger" for a
description of the 5,000 Northern Lehigh stock options that will be converted

                                      -41-

<PAGE>
into the right to  receive  17,850  options  to  acquire  Harleysville  National
Corporation common stock upon completion of the merger.

Management and Operations Following the Merger

     The  Boards  of  Directors  of   Harleysville   National   Corporation  and
Harleysville  National  Corporation  North following the merger will include the
same persons who are members of those Boards of Directors immediately before the
merger,  each of whom will serve until his or her  successor  is elected and has
qualified.  In addition,  Joseph G.  Bechtel,  Charles J.  Breidinger,  Carol J.
Simcoe and Charles W. Stopp, who previously  served on the Board of Directors of
Northern  Lehigh,  will be  appointed  to the Board of Directors of the Citizens
National Bank to serve until their successors have been duly elected,  qualified
or appointed.

     The directors added to the Board of Directors of he Citizens  National Bank
will  receive the same fees and  benefits  for their  membership  as the present
members of the bank's Board receive.  In 1998, the each Director of The Citizens
National  Bank of  Lansford  receives  a fee of $250.00  for each board  meeting
attended,  an annual  retainer of  $3,500.00,  and receives a fee of $150.00 for
each committee  meeting  attended.  All together,  as of September 30, 1998, the
Board  of  Directors  of  The  Citizens   National  Bank  of  Lansford  received
$47,025.00.

     Harleysville  National  Corporation 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 greater. 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.

     On or  promptly  after  the  merger  and for a period  of at least one year
thereafter,  the  current  members  of the Board of  Directors  of The  Citizens
National Bank of Slatington  will become an Advisory  Board of Directors for the
Slatington  Area.  Thomas D.  Oleksa  will serve as a  non-voting  member of the
Advisory  Board.  For one year following the merger,  each of the members of the
Advisory Board,  will receive  $250.00 per quarter as compensation  for services
rendered in their capacity as a member of the Advisory Board.

     For at least one year following the merger,  The Citizens  National Bank of
Slatington's  employees,  who are employed in good standing and actively at work
on the day of the merger,  will be offered  employment  and  retained at current
salary levels by the Citizens National Bank,  Harleysville  National Corporation
or an affiliate of  Harleysville  National  Corporation,  subject to the ongoing
needs  of  Harleysville   National   Corporation,   the  Harleysville   National
Corporation's  affiliate  and/or the  Citizens  National  Bank.  All  continuing
employees  will be entitled to participate in all benefit plans in effect on the
day of the  merger,  at  Harleysville  National  Corporation  or the  respective
Harleysville National Corporation affiliate,  as the case may be, as provided by
the terms of the particular plans. All benefits of the continuing  employees who
are

                                      -42-

<PAGE>
employed by Harleysville  National Corporation will be maintained at a level not
less than equal to the  benefits  enjoyed by the  employees  of Northern  Lehigh
prior to the merger with  changes as may be deemed  appropriate  by the Board of
Directors of The Citizens National Bank of Lansford. The former employees of The
Citizens  National Bank of  Slatington  will receive  service  credit from their
respective hire dates for employment at The Citizens National Bank of Slatington
for purposes of eligibility  and vesting  requirements,  but not for purposes of
benefit  accrual,   under  the  respective   Harleysville  National  Corporation
affiliate's  benefit  plans,  and service  credit from the day of the merger for
purposes  of benefit  calculation  under the  respective  Harleysville  National
Corporation affiliate's benefit plans.

     As part of the transaction, Harleysville National Corporation, The Citizens
National  Bank of  Lansford,  Northern  Lehigh,  The Citizens  National  Bank of
Slatington and Francis P. Burbidge, President and Chief Executive Officer of The
Citizens National Bank of Slatington and a Director of Northern Lehigh,  entered
into a Release  Agreement.  In the release  agreement,  Mr.  Burbidge  agreed to
release  any and all rights he might have under his  employment  agreement  with
Northern  Lehigh.  In  addition,  Mr.  Burbidge  has entered  into an  Executive
Employment  Agreement and a Consulting Agreement with The Citizens National Bank
of Lansford. We summarize the major provisions of these contracts below.

     Mr.  Burbidge's  employment  agreement  with The Citizens  National Bank of
Lansford has a one year term,  beginning on the day of the merger. He will serve
as a Vice  President  of The  Citizens  National  Bank  of  Lansford,  reporting
directly to the President.  The employment  agreement provides that Mr. Burbidge
will receive an annual salary of $98,000.  In addition,  the agreement provides,
among other things,  that Mr.  Burbidge has a right to  participate in any bonus
plan approved by the Board of Directors  and  insurance,  vacation,  pension and
other fringe benefits and perquisites.

     If Mr. Burbidge's  employment is terminated  without "Cause," as defined in
the employment agreement, Mr. Burbidge is entitled to receive his benefits under
the  agreement.  If Mr.  Burbidge is  terminated  for "Cause," as defined in the
employment agreement,  his benefits terminate as of the date of his termination.
Mr. Burbidge's  benefits terminate upon his death and, upon his disability.  The
employment  agreement also contains provisions  restricting Mr. Burbidge's right
to compete with Harleysville National Corporation and The Citizens National Bank
of Lansford.

     The Citizens National Bank of Lansford and Mr. Burbidge also entered into a
consulting  agreement,  dated as of July 28, 1998,  but effective one year after
the merger of his employment agreement (described above). Under the terms of the
consulting agreement,  Mr. Burbidge will act as an advisor and consultant to The
Citizens  National  Bank of Lansford  for a period of one year.  Mr.  Burbidge's
compensation will be $98,000, paid in four equal quarterly installments.  In the
event of Mr.  Burbidge's death or disability,  his benefits under the consulting
agreement will continue.


                                      -43-

<PAGE>

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

Federal Income Tax Consequences

     Grant  Thornton,  LLP,  independent  accountant for  Harleysville  National
Corporation,  will give an opinion at closing  that will state that for  federal
income tax purposes:

     *    Neither Harleysville  National  Corporation nor Harleysville  National
          Corporation  North will recognize gain or loss on the incorporation of
          Harleysville  National  Corporation  North or the  contribution of The
          Citizens  National  Bank of Lansford  stock to  Harleysville  National
          Corporation  North in exchange for Harleysville  National  Corporation
          North stock.

     *    The  initial  basis  and  holding  period  of  Harleysville   National
          Corporation in the Harleysville  National  Corporation  North stock it
          acquires in exchange for The Citizens  National Bank of Lansford stock
          will be  equal  to its  basis  and  holding  period  for The  Citizens
          National Bank of Lansford stock delivered in the exchange.

     *    The  initial  basis  and  holding  period  of  Harleysville   National
          Corporation  North in The Citizens  National Bank of Lansford stock it
          receives from  Harleysville  National  Corporation in the  transaction
          will be the same as  Harleysville  National  Corporation's  basis  and
          holding period in that stock.

     *    The merger of  Northern  Lehigh  with and into  Harleysville  National
          Corporation  North  will  constitute  a  "Reorganization"  within  the
          meaning of sections 368(a)(2)(D) of the Code.

     *    Harleysville  National  Corporation,  Northern Lehigh and Harleysville
          National   Corporation  North  will  be  regarded  as  "Parties  to  a
          Reorganization"  within the meaning of section 368(b) of the Code with
          respect to the merger of Northern  Lehigh  with and into  Harleysville
          National Corporation North.

     *    No gain or loss  will be  recognized  by the  former  shareholders  of
          Northern  Lehigh upon the  exchange of their  Northern  Lehigh  common
          stock for Harleysville National Corporation common stock.

     *    The basis and holding periods of former  Northern Lehigh  shareholders
          in their Northern  Lehigh common stock will carry over to Harleysville
          National Corporation common stock they receive in the transaction.

     *    Former  Northern  Lehigh  shareholders   receiving  cash  in  lieu  of
          fractional shares of Harleysville  National  Corporation  common stock
          will have gain or loss on such  exchanges  equal to the  excess of the
          cash  received in lieu of such  fractional  shares over their basis in
          their  Northern  Lehigh  common  stock  allocable  to  the  fractional
          interests exchanged therefor. The gain or loss will constitute capital
          gain or loss, if the shares of Northern  Lehigh common stock qualified
          as capital  assets in the hands of the exchanging  shareholder  within
          the meaning of section 1221 of the

                                      -44-

<PAGE>

          Code and the  capital  gain or loss  will be short  term or long  term
          depending upon the shareholder's  holding period for the shareholder's
          Northern Lehigh common stock.

     *    Former Northern Lehigh shareholders  exercising dissenters rights with
          respect to their  Northern  Lehigh common stock will have gain or loss
          on the receipt of cash for their Northern Lehigh common stock equal to
          the excess of the cash  received  over their  basis in their  Northern
          Lehigh common stock. The gain or loss will constitute  capital gain or
          loss,  if the shares of Northern  Lehigh  common  stock  qualified  as
          capital assets in the hands of the exchanging  shareholder  within the
          meaning of section 1221 of the Code and, the capital gain or loss will
          be short term or long term depending upon such  shareholder's  holding
          period for the shareholder's Northern Lehigh common stock.

     *    Stock  option  holders  will  not  recognize  any  gain or loss on the
          exchange of their Northern  Lehigh options for  Harleysville  National
          Corporation options.

     *    Harleysville  National  Corporation  North  will  succeed  to the  tax
          attributes of Northern Lehigh including net operating loss carryovers,
          credit  carryovers and accounting  methods  subject to any limitations
          imposed under section 381 and 382 of the Code.

     *    Harleysville National Corporation's basis in its Harleysville National
          Corporation  North  stock will be  increased  by the basis of Northern
          Lehigh in its assets immediately prior to the merger.

     *    The bank merger will constitute a "Reorganization"  within the meaning
          of section 368(a)(1)(A) of the Code.

     *    Harleysville National Corporation North, The Citizens National Bank of
          Slatington and The Citizens National Bank of Lansford will be regarded
          as "Parties to a Reorganization"  within the meaning of section 368(b)
          of the Code in regard to the bank merger.

     *    No gain or loss will be  recognized  by The Citizens  National Bank of
          Slatington  or The  Citizens  National  Bank of  Lansford  in the bank
          merger.

     *    The  basis  and  holding  periods  of The  Citizens  National  Bank of
          Slatington in its assets  transferred to The Citizens National Bank of
          Lansford in the bank merger will  carryover to The  Citizens  National
          Bank of Lansford and become The Citizens  National  Bank of Lansford's
          basis and holding periods in those assets.

     *    As a result of the bank merger, The Citizens National Bank of Lansford
          will succeed to the tax  attributes  of The Citizens  National Bank of
          Slatington including net operating loss carryovers,  credit carryovers
          and  accounting  methods  subject  to any  limitations  imposed  under
          sections 381 and 382 of the Code.

     *    Upon   consummation   of  the  bank  merger,   Harleysville   National
          Corporation  North's  basis  in its  The  Citizens  National  Bank  of
          Lansford  stock  will be  increased  by the  basis in its stock of The
          Citizens National Bank of Slatington immediately prior to the merger.

     This is intended only as a general discussion of certain federal income tax
consequences  of the merger  under  present  law.  We urge each  shareholder  of
Northern Lehigh to consult his or

                                      -45-

<PAGE>

her own tax advisor  concerning the particular tax consequences of the merger as
they affect his or her  individual  circumstances,  including  the impact of any
applicable estate, gift, state, local, foreign or other tax.

Investment  Agreement

     As part of the  agreement,  Northern  Lehigh has entered into an investment
agreement with Harleysville National Corporation, pursuant to which Harleysville
National Corporation has an option to acquire certain shares of Northern Lehigh.
The investment  agreement is attached as Exhibit "B" to the agreement,  which is
attached to this proxy statement/prospectus as Annex A.

     The investment agreement gives Harleysville  National Corporation an option
to  purchase,  under  certain  circumstances,  up to 27,760  shares of  Northern
Lehigh's  common  stock at an  exercise  price of $57.00 per  share,  subject to
certain adjustments, which are contained in the investment agreement.

     The option is designed to compensate  Harleysville National Corporation for
its risks,  costs and expenses and the commitment of resources  associated  with
the merger in the event the merger is not completed due to an attempt by a third
person to gain control of Northern Lehigh .

     The option also includes  provisions  giving  Northern  Lehigh the right to
repurchase  shares of Northern  Lehigh  common  stock issued under the option in
certain  limited  circumstances  and  includes  provisions  for  issuance  of  a
substitute  option to purchase  shares of the surviving or acquiring  company in
the event of a merger or other acquisition of Northern Lehigh.

     Unless the merger is completed  or unless,  certain  conditions  to closing
become incapable of occurring or Harleysville  National Corporation has breached
of  the  agreement,   Harleysville  National   Corporation's  rights  under  the
investment  agreement  will not  terminate  until the later of June 30, 1999, or
eighteen  (18) months  after the date of an event ( described  in paragraph 2 of
the  investment  agreement)  that  permits  exercise  or sale of the  option  by
Harleysville   National   Corporation.   As  of   the   date   of   this   proxy
statement/prospectus,  the parties to the investment  agreement are not aware of
any  event  that  would  give  Harleysville  National  Corporation  the right to
exercise the option.

Accounting Treatment

     The agreement  contemplates that the merger will be treated as a pooling of
interests  for  financial  accounting  purposes.  This  accounting  treatment is
different from a purchase transaction.  Under this accounting method, the assets
and  liabilities  of  Northern  Lehigh will be carried  forward to  Harleysville
National  Corporation  North at their  historical  recorded  bases.  Results  of
operations of Harleysville  National  Corporation North 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
corporations for prior periods will be combined, reclassified

                                      -46-

<PAGE>
and conformed,  as appropriate,  to reflect the combined  financial position and
results of operations for Harleysville National Corporation North.

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

Restriction on Resale of Stock Held By Affiliates

     The shares of Harleysville  National  Corporation 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 Northern  Lehigh,  except
those  former  shareholders  who are deemed  "affiliates"  of Northern  Lehigh ,
within the meaning of Commission Rules 144 and 145. In general terms, any person
who is an executive  officer,  director or 10% shareholder of Northern Lehigh at
the time of the meeting may be deemed to be an affiliate of Northern  Lehigh for
purposes of Commission Rules 144 and 145. This proxy  statement/prospectus  does
not cover resales of shares of Harleysville National Corporation common stock to
be issued to affiliates of Northern Lehigh in connection with the transaction.

     Harleysville  National Corporation common stock received by persons who are
deemed to be affiliates of Northern Lehigh may be resold only:

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

National  Corporation acquired all of the outstanding stock of Security National

outstanding common stock of Farmers & Merchants Bank (Honesdale,  P.A.). Farmers
& 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
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 National Corporation,  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  National  Corporation's  subsidiaries  and  it  also  exposes
Harleysville

                                      -52-

<PAGE>

National  Corporation  and its  subsidiaries  to potential  losses upon borrower
default.  In order to minimize the  occurrence  of loss,  Harleysville  National
Corporation'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 National Corporation'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  National  Corporation  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 7,037,814 shares were
issued  and  outstanding  as  of  September  30,  1998.   Harleysville  National
Corporation  also  has  3,000,000  shares  of  preferred  stock  authorized  for
issuance. No preferred stock is outstanding as of September 30, 1998.

Dividends

     The holders of Harleysville  National Corporation common stock are entitled
to receive  dividends  when, as and if declared by the Board of Directors out of
legally available funds. Harleysville National Corporation 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  National  Corporation to pay dividends to its
shareholders is dependent primarily upon the earnings and financial condition of
The Harleysville  National Bank and Trust Company, The Citizens National Bank of
Lansford, and Security National Bank.  Harleysville National Corporation expects
to  obtain  funds  for  the  payment  of  dividends  on  Harleysville   National
Corporation Stock, for the foreseeable future,  primarily from dividends paid to
Harleysville  National  Corporation  by its  subsidiaries.  These  dividends are
subject to certain statutory limitations.

     Under  applicable  federal laws, the dividends that  Harleysville  National
Corporation's banking subsidiaries may pay without prior regulatory approval are
subject  to  certain  prescribed  limitations.   Because  Harleysville  National
Corporation'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

                                      -53-

<PAGE>
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 National Corporation paid cash dividends of $0.91 per share in
1997,  adjusted  to  reflect a 5% stock  dividend  effective  on June 30,  1997.
Harleysville  National  Corporation  paid cash dividends of $.24, $.24 and $.25,
respectively, for each of the first three quarters of 1998.

Liquidation

     In the event of  liquidation,  dissolution  or winding  up of  Harleysville
National  Corporation  ,  Harleysville  National  Corporation  shareholders  are
entitled to share ratably in all assets  remaining after payment of liabilities,
subject  to prior  distribution  rights  of  Harleysville  National  Corporation
preferred stock, if any, then  outstanding.  On September 30, 1998, no shares of
Harleysville  National  Corporation  preferred  stock were issued or outstanding
under the Articles of Incorporation of Harleysville National Corporation.

Dividend Reinvestment Plan

     Harleysville  National  Corporation has a Dividend  Reinvestment  and Stock
Purchase Plan.  Shareholders of Harleysville  National  Corporation 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  National
Corporation  common  stock  either in the market or from  Harleysville  National
Corporation's  authorized  but unissued  shares of common  stock.  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
National  Corporation  common  stock  held  for  the  account  of  participating
shareholders and are voted by the plan agent as instructed by each participating
shareholder.

Securities Laws

     Harleysville National Corporation, as a business corporation, is subject to
the  registration  and prospectus  delivery  requirements of the Securities Act.
Harleysville  National Corporation is also subject to similar requirements under
state  securities laws. The Harleysville  National  Corporation  common stock is
registered  with the  Commission  under  Section  12(g) of the Exchange Act, and
Harleysville  National  Corporation is subject to the periodic reporting,  proxy
solicitation and insider trading requirements of the Exchange Act. The executive
officers,  directors and those who are beneficial owners of more than 10 percent
of the issued and outstanding shares of Harleysville National Corporation common
stock are subject to certain  restrictions  affecting their right to sell shares
of Harleysville  National  Corporation  common stock owned beneficially by them.
Specifically,  each such person is subject to the beneficial ownership reporting
requirements under the short-swing profit recapture provisions of Section 16

                                      -54-

<PAGE>

of the Exchange  Act and may sell shares of  Harleysville  National  Corporation
common stock only:

     *    in compliance with the provisions of Commission Rule 144;

     *    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 under the Securities Act.

Anti-takeover Provisions

     The Pennsylvania Business Corporation Law of 1988 and Harleysville National
Corporation's  amended  Articles of  Incorporation  and amended  Bylaws  provide
numerous provisions that may be deemed to be anti-takeover in nature, both as to
purpose  and  effect.  There  are  four  major  anti-takeover  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 herein might be to
deter a tender offer that a majority of the shareholders  might possibly view to
be in their best interest as the offer might include a substantial  premium over
the market price of  Harleysville  National  Corporation's  common stock at that
time.  In  addition,   these   provisions  may  have  the  effect  of  assisting
Harleysville National Corporation's current management in retaining its position
and placing it in a better  position  to resist  changes  that the  shareholders
might want to make if  dissatisfied  with the conduct of  Harleysville  National
Corporation's business.

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

     *    call a special meeting of shareholders; and
     
     *    propose an amendments to the Articles of Incorporation.

One  effect of these  provisions  may be to  prevent  the  calling  of a special
meeting of shareholders  for the purpose of considering a merger,  consolidation
or other corporate combination which does not have the approval of a majority of
the members of  Harleysville  National  Corporation's  Board of Directors.  This
provision may have the effect of making Harleysville  National  Corporation 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.

     These two  provisions  may discourage  attempts by  shareholders  to call a
special  meeting  of  shareholders.   They  also  provide  a  greater  time  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  provisions  of  Pennsylvania  law 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

                                      -55-

<PAGE>
Directors or of its Executive Committee if, in their judgment, there are matters
to be  acted  upon  which  are in the best  interest  of  Harleysville  National
Corporation and its shareholders.

     Harleysville National  Corporation's  Articles of Incorporation and amended
Bylaws  contain a number  of  additional  provisions  that  could be  considered
anti-takeover in purpose and effect. These provisions include:

     *    authorization   of   30,000,000   shares  of   Harleysville   National
          Corporation 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 percent of
          Harleysville  National   Corporation's  common  stock  to  approve  an
          amendment to Harleysville  National  Corporation'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 percent of
          Harleysville National  Corporation'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 percent 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  National
Corporation's  outstanding  shares a veto power over any merger,  consolidation,
dissolution or liquidation of Harleysville National Corporation, the sale of all
or  substantially  all of its assets or an  amendment  to its  Bylaws  unless 75
percent  of  all  members  of the  Board  of  Directors  and a  majority  of the
shareholders believes that the transaction is desirable and beneficial.  Without
these   provisions   in   Harleysville   National   Corporation's   Articles  of
Incorporation  and  Bylaws,  the  affirmative  vote of at  least a  majority  of
Harleysville  National  Corporation's  common stock outstanding 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 the amended
Bylaws of Harleysville National  Corporation.  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 also  tends to
discourage a tender offer or takeover bid. This  provision may also be deemed to
be  anti-takeover  in nature.  In  addition,  a  classified  board makes it more
difficult for a majority of the  shareholders to promptly change the composition
of the board of  directors  even  though such  prompt  change may be  considered
desirable for them.

     Harleysville  National  Corporation's  amended  Articles  of  Incorporation
contain  an  additional  anti-takeover  provision  that  enables  the  Board  of
Directors to oppose a tender offer on the basis of factors  other than  economic
benefit. Based on the Board's responsibilities to certain

                                      -56-

<PAGE>
constituent groups,  including Harleysville National Corporation's  subsidiaries
and the communities that they serve, the Board may consider factors such as:

     *    the impact the acquisition of Harleysville  National Corporation 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

     The Bylaws of Harleysville National Corporation 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 Harleysville  National  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
National Corporation,  Harleysville National Corporation 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  Northern  Lehigh  will  become
shareholders of Harleysville National Corporation. There are certain differences
in the rights of shareholders of these two companies These differences arise out
of differences in the articles of incorporation and bylaws of the two companies.
The most  significant of these  differences are those relating to  anti-takeover
protection and public registration.

     The Bylaws of Harleysville  National  Corporation  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 Northern  Lehigh Board of Directors is  classified  and divided
into three classes of directors and, accordingly, approximately one-third of the
directors are elected each year for a term of three years. 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 the only reason
for such a change may be the  performance  of the existing  directors.  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 two annual meetings of Northern
Lehigh's  shareholders  to  replace a majority  of  Northern  Lehigh's  Board of
Directors.

     In addition to the  classification of the Board of Directors,  the Articles
of  Incorporation  and Bylaws of  Harleysville  National  Corporation  include a
number of provisions that are

                                      -57-

<PAGE>

intended  to protect  the  shareholders  of  Harleysville  National  Corporation
(including  the  present  shareholders  of  Northern  Lehigh , who  will  become
shareholders of Harleysville  National  Corporation  following the merger),  but
which may be considered to be  anti-takeover in nature and may serve to entrench
the current management of Harleysville National Corporation. See "DESCRIPTION OF
HARLEYSVILLE  NATIONAL  CORPORATION  AND  DESCRIPTION OF  HARLEYSVILLE  NATIONAL
CORPORATION COMMON STOCK--Anti-takeover Provisions."

     Harleysville  National  Corporation  common stock,  unlike  Northern Lehigh
common  stock,  is  registered  with the  Commission  under Section 12(g) of the
Exchange Act. As a result,  Harleysville  National Corporation is subject to the
periodic reporting,  proxy solicitation and insider trading  requirements of the
Exchange  Act,  which  do not  apply  to  Northern  Lehigh.  Pursuant  to  these
requirements, Harleysville National Corporation makes available to shareholders,
potential  investors and the general public a significant  amount of information
regarding  Harleysville  National  Corporation in the form of proxy  statements,
periodic reports and other Commission filings. In addition, directors, executive
officers and beneficial  shareholders  of more than 10 percent 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.

     The  material   differences   between  Northern  Lehigh  common  stock  and
Harleysville   National  Corporation  common  stock  and  the  rights  of  their
respective  holders,  as of September 30, 1998,  are summarized in the following

Northern Lehigh Common Stock Market Price and Dividends

     The Northern Lehigh common stock has historically  been traded on a 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.
The  last  reported   sale  of  Northern   Lehigh  common  stock  before  public
announcement  of the agreement  and related  merger was a trade of 900 shares at
$56.00 per share on May 19,  1998.  The last  reported  sale of Northern  Lehigh
common stock, prior to the date of this proxy statement/prospectus,  as reported
on the OTC  Bulletin  Board was 100 shares at $101.50 per share on November  10,
1998.  There were 268 holders of record of Northern  Lehigh  common  stock as of
September 30, 1998.

     Northern Lehigh shareholders are entitled to receive the dividends when, as
and if  declared  by the Board of  Directors  out of  legally  available  funds.
Northern  Lehigh  has   historically   paid  quarterly  cash  dividends  to  its
shareholders on or about April 1, July 1, October 1, and January 1 of each year.
The ability of Northern Lehigh to pay dividends to its shareholders is dependent
upon receipt of dividends from The Citizens National Bank of Slatington.

     Under  federal law, the  approval of the Office of the  Comptroller  of the
Currency is required  for the payment of  dividends  in any  calendar  year by a
subsidiary national bank if the total of all dividends declared by the bank in a
calendar  year exceeds that bank's net profits for that year  combined  with its
retained  net  profits  for the  preceding  two  calendar  years.  Moreover,  no
dividends  may be paid by a national  bank if its  "losses"  equal or exceed its
undivided profits account, and no dividend may be paid in an amount in excess of
its "net profits then on hand." In addition,  the Office of the  Comptroller  of
the  Currency may find a dividend  payment  which  otherwise  meets the criteria
specified in the law, nonetheless to constitute an unsafe or unsound practice.

     In accordance  with the  regulatory  restrictions  described  above,  as of
December 31, 1997, The Citizens  National Bank of Slatington  had  approximately
$984,784 available for the payment of dividends.  The agreement permits Northern
Lehigh to make normal dividend payments, not in excess of $0.44 per share during
the fourth quarter of 1998 to its  shareholders,  consistent with past practice,
prior to the day of the merger.

     Northern  Lehigh paid cash  dividends of $1.51 per share in 1997,  and $.44
for the first, second and third quarters of 1998.

Year 2000 Issue

     The Year 2000 Problem

     The following  section  contains  forward-looking  statements which involve
risks and uncertainties.  Northern Lehigh's actual impact of the Year 2000 issue
could materially differ from that which is anticipated in these  forward-looking
statements as a result of certain factors identified below.

                                      -62-

<PAGE>

     The Year 2000  problem  issue is the  result  of  potential  problems  with
software and computer systems or any equipment with computer chips (collectively
"systems")  that store the year portion of the date as just two digits (e.g.  98
for 1998).  Systems using this two-digit  approach will not be able to determine
whether "00"  represents the year 2000 or 1900.  The problem,  if not corrected,
will make those systems fail  altogether or, even worse,  allow them to generate
incorrect  calculations  causing a  disruption  of normal  computer  and related
operations.

     Readiness Efforts

     In 1997, a comprehensive  project plan to address the Year 2000 problem and
related issues as those relate to The Citizens National Bank of Slatington's and
its affiliates(1)  operations was developed,  approved by the Board of Directors
and  implemented.  The scope of the plan  includes  five  phases  of  Awareness,
Assessment,  Renovation,  Validation  and  Implementation  as defined by Federal
Financial  Institutions  Examination Council and the banking regulatory agencies
which regulate Northern Lehigh and The Citizens National Bank of Slatington.

     A project team that  consists of key members of The Citizens  National Bank
of Slatington's  technology staff,  representatives of functional business units
and senior management was developed. Additionally, the duties of the Senior Vice
President and Chief  Operations  Officer were aligned to serve  primarily as the
Year 2000 project manager.

     As assessment of the impact of the Year 2000 issue on The Citizens National
Bank of  Slatington's  computer  systems  has been  completed.  The scope of the
project also includes other operational and environmental systems since they may
be impacted if  embedded  computer  chips  control  the  functionality  of those
systems.  From the  assessment,  The Citizens  National Bank of  Slatington  has
identified and prioritized  those systems deemed to be mission critical or those
that have a significant impact on normal operations.

     Slatington relies on third party vendors and service providers for its data
processing   capabilities   and  to  maintain  its  computer   systems.   Formal
communications  with those providers of data processing  capabilities  and other
external  counterparties were initiated in 1997 and 1998 to assess the Year 2000
readiness  of their  products  and  services.  Their  progress in meeting  their
targeted  schedules is being  monitored for any indication  that they may not be
able to address the problems in time. Thus far,  responses indicate that most of
the significant  providers  currently have compliant  versions  available or are
well into the  renovation  and testing  phases  with  completion  scheduled  for
sometime in 1998. However,  The Citizens National Bank of Slatington can give no
guarantee  that the systems of these service  providers and vendors on which The
Citizens National Bank of Slatington's systems rely will be timely renovated.

     Additionally,  The Citizens  National Bank of Slatington has  implemented a
plan to manage the potential  risk posed by the impact of the Year 2000 issue on
its major  customers.

Formal communications have been initiated, and the assessment is scheduled to be
significantly completed by December 31, 1998.

     Current Status

     The project team estimates that The Citizens  National Bank of Slatington's
Year 2000 readiness project is 53% complete and that the activities  involved in
assessing external risks and operational  issues are 69% completed overall.  The
following  table  provides a summary of the  current  status of the five  phases
involved and a projected timetable for completion.

     Costs

     Slatington has thus far primarily used and expects to continue to primarily
use internal resources to implement its readiness plan and to upgrade or replace
and test systems affected by the Year 2000 issue. The total cost to The Citizens
National  Bank of Slatington of these Year 2000  compliance  activities  has not
been and is not anticipated to be material to its financial  position or results
of  operations  in any given  year.  In total,  The  Citizens  National  Bank of
Slatington estimates that its costs, excluding personnel expenses, for Year 2000
remediation and testing of its computer systems will amount to less than $50,000
over the three-year period from 1997 through 1999. Not included in this estimate
is the cost to replace  fully  depreciated  systems  during this  period,  which
occurs in the normal course of business and is not directly  attributable to the
Year 2000 issue.

     The  costs  and the  timetable  in  which  The  Citizens  National  Bank of
Slatington  plans to complete the Year 2000  readiness  activities  are based on
management's  best estimates,  which were derived using numerous  assumptions of
future events including the continued  availability of certain resources,  third
party  readiness  plans  and  other  factors.  The  Citizens  National  Bank  of
Slatington  can make no guarantee  that these  estimates  will be achieved,  and
actual results could differ from such plans.

     Risk Assessment

     Based upon current information related to the progress of its major vendors
and service  providers,  management has determined that the Year 2000 issue will
not  pose  significant  operational  problems  for its  computer  systems.  This
determination is based on the ability of those vendors and service  providers to
renovate,  in a timely  manner,  the products and services on which The Citizens
National Bank of Slatington's  systems rely. However, The Citizens National Bank
of Slatington can give no guarantee that the systems of these  suppliers will be
timely renovated.

     Contingency Plan

     Realizing  that some  disruption  may occur despite its best  efforts,  The
Citizens National Bank of Slatington is in the process of developing contingency
plans for each  critical  system in the event that one or more of those  systems
fail. While this is an ongoing process, The Citizens National Bank of Slatington
expects to have the plan substantially documented by December 31, 1998.

                            IMPACT OF YEAR 2000 ISSUE

     The following  section  contains  forward-looking  statements  that involve
risks and uncertainties.  Harleysville  National  Corporation's actual impact of
the Year 2000 issue could  materially  differ from that which is  anticipated in
these  forward-looking  statements  as a result of  certain  factors  identified
below.

     The "Year  2000  Issue" is the  result of  computer  programs  having  been
written using two digits rather than four to define the applicable  year. Any of
Harleysville  National  Corporation's  computer systems that have date-sensitive
software or date- sensitive hardware may recognize a date using "00" as the Year
1900  rather  than the Year  2000.  This  could  result in a system  failure  or
miscalculations  causing  disruptions  of  operations,  including,  among  other
things,  a temporary  inability to process  transactions,  send  statements,  or
engage in similar normal business activities.

     Based on an  ongoing  assessment,  Harleysville  National  Corporation  has
determined  that it will be  required  to  modify  or  replace  portions  of its
software  and  hardware so that its  computer  systems  will  properly use dates
beyond December 31, 1999.  Harleysville  National Corporation presently believes
that as a  result  of  modifications  to  existing  software  and  hardware  and
conversions to new software and hardware,  the Year 2000 Issue can be mitigated.
However,  if  such  modifications  and  conversions  are  not  made,  or are not
completed on a timely basis,  the Year 2000 Issue could have a material  adverse
impact on the operations of Harleysville National Corporation.

     Harleysville  National Corporation has initiated formal communications with
all of its vendors and large  commercial  customers to  determine  the extent to
which  Harleysville  National  Corporation is vulnerable to those third parties'
failure  to  remediate  their  own  Year  2000  Issue.   Harleysville   National
Corporation's estimated Year 2000 project costs include the costs and time

                                      -65-

<PAGE>

associated with the impact of a third party's Year 2000 Issue,  and are based on
presently available information.

     For significant  vendors,  Harleysville  National Corporation is validating
that they are Year 2000 compliant.  If Harleysville National Corporation has not
validated  their  compliance  by  December  31,  1998,   Harleysville   National
Corporation  will  make  plans to  switch  to a new  vendor  or  system  that is
compliant.  For insignificant vendors,  Harleysville National Corporation is not
necessarily  validating  that they are Year  2000  compliant.  However,  for any
insignificant  vendor who  responds  that they will not be compliant by December
31, 1998,  Harleysville  National  Corporation  will seek a new vendor or system
that is compliant.  For large commercial loan customers,  Harleysville  National
Corporation will take appropriate action based upon the customer's response.

     Harleysville  National  Corporation  has used both  internal  and  external
resources to reprogram,  or replace, and test its software and hardware for Year
2000 modifications. Harleysville National Corporation plans to complete the Year
2000 project  within 9 months or no later than June 30,  1999,  for all critical
systems.  The total cost of the Year 2000 and  systems  conversion  projects  is
estimated at $300,000.  Of the total projects' cost,  approximately  $100,000 is
attributable  to the  purchase  of new  software  and  hardware  which  will  be
capitalized.  We have expensed  $125,000 to date, and we plan to expense $75,000
more before  December 31, 1999.  These costs are not expected to have a material
effect on the results of operations of Harleysville National Corporation.

     The  costs of the  projects  and the date on  which  Harleysville  National
Corporation  plans to  complete  both the Year 2000  modifications  and  systems
conversions  are  based on  management's  best  estimates,  which  were  derived
utilizing  numerous   assumptions  of  future  events  including  the  continued
availability  of certain  resources,  third party  modification  plans and other
factors.  However,  there  can be no  guarantee  that  these  estimates  will be
achieved and actual results could differ  materially from those plans.  Specific
factors that might cause such material  differences include, but are not limited
to, the availability and cost of personnel  trained in this area, the ability to
locate and correct all relevant computer codes, and similar uncertainties.

     As a bank  holding  company,  Harleysville  National  Corporation  and  its
subsidiaries  are subject to the  regulation  and  oversight of various  banking
regulators.  Their  oversight  includes the  provision  of specific  timetables,
programs and guidance regarding Year 2000 issues.  Regulatory examination of the
holding  company and its  subsidiaries'  Year 2000  programs are  conducted on a
quarterly basis and reports are submitted by Harleysville  National  Corporation
to the banking regulators on a periodic basis.

Investment Securities

     Total securities of $8,355,000 increased $2,876,000 from September 30, 1997
to September 30, 1998. This increase is the result of The Citizens National Bank
of Slatington increasing the securities held to maturity portfolio by $4,205,000
and reducing the  securities  available for sale  portfolio by  $1,329,000.  The
primary  increase  in the  held to  maturity  portfolio  was in  corporate  debt
securities.   The  September  30,  1998  securities  portfolio  did  not  change
significantly  from the December 31, 1997 and 1996  portfolios of $8,336,000 and
$8,426,000, respectively.

     The September 30, 1998 federal funds sold of $8,564,000  was $434,000 lower
than the  September  30,  1997  balance  of  $8,998,000.  Federal  funds sold at
September  30, 1998 were higher than the December 31, 1997 balance of $1,396,000
and the December 31, 1996 balance of $2,140,000.

     There are no significant  concentrations of securities (greater than 10% of
shareholders'  equity)  in any  individual  security  issuer,  except  for  five
corporate debt securities. These corporate debt securities mature within a three
month period and have an aggregate  book value of $4,963,000  and a market value
of $4,959,000.  The maturity analysis of investment securities held to maturity,
including the weighted average yield for each category as of September 30, 1998,
is as follows:

Loans

     Slatington  grants commercial loans,  residential  mortgages,  and consumer
loans to customers  located  primarily  within the Lehigh  Valley.  The Citizens
National Bank of Slatington has a  concentration  of credit in commercial  loans
and  exposure to credit loss can be  adversely  impacted by  downturns  in local
economic and employment conditions.

     Loans grew  $1,119,000,  or 2.0% from  $56,055,000 at September 30, 1997 to
$57,174,000  at September  30, 1998.  This growth was primarily the result of an
increase in real estate related  loans.  The September 30, 1998 loan balance was
3.5% lower than the  December  31,  1997 loan  balance  and 2.0% higher than the
December 31, 1996 loan balance. The reduction in loans from December 31, 1997 to
September 30, 1998 was primarily the result of lower real estate related loans.

Major  classifications  of loans are summarized as follows at September 30, 1998
and 1997, and December 31, 1997 and 1996:

A loan is generally  classified  as  nonaccrual  when  principal or 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 in full of
principal or interest is not expected. Delinquent loans past due 90 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  nonaccrual  status,  were  accounted  for as
troubled  debt  restructurings  or were  delinquent  90 days or more  and  still
accruing interest:

     The  provision  for loan  losses is based upon a credit  review of the loan
portfolio,  past loan loss  experience,  current  economic  conditions and other
pertinent  factors  which  form a basis  for  determining  the  adequacy  of the
allowance for possible loan losses. In the opinion of management,  the aggregate
amount reserved is deemed to be adequate to absorb future loan losses.

     The  allowance  for possible  loan losses of $743,000 at September 30, 1998
was 1.30% of loans,  compared  to 1.13% of loans at  September  30,  1997.  This
increase is due to The Citizens

     Total  deposits of $68,166,000  at September 30, 1998 were  $3,957,000,  or
6.2% higher than the  September 30, 1997 balance of  $64,209,000.  This increase
was primarily the result of increases in time  deposits,  money market  deposits
and interest-bearing checking accounts. These increases were partially offset by
decreases in savings and  noninterest-bearing  checking accounts.  The September
30, 1998 deposit  balance grew  $4,708,000 from the December 31, 1997 balance of
$63,458,000  and  $6,119,000  from the  December  31,  1996  deposit  balance of
$62,047,000.

Deposits are  summarized as follows at September 30, 1998 and 1997, and December
31, 1997 and 1996:

Capital

     Quantitative  measures established by regulation to ensure capital adequacy
require  the  maintenance  of  minimum  amounts  and  ratios of total and Tier 1
capital to risk-weighted  assets.  Management believes, as of September 30, 1998
that  Northern  Lehigh and The Citizens  National  Bank of  Slatington  meet all
capital adequacy requirements to which they are subject.

     The minimum for the Tier 1 ratio is 4.0%, and the total capital ratio (Tier
1 plus Tier 2 capital  divided by  risk-adjusted  assets)  minimum  is 8.0%.  At
September 30, 1998,  Northern  Lehigh's Tier 1  risk-adjusted  capital ratio was
14.0%, and the total risk-adjusted  capital ratio was 15.3%, both well above the
regulatory  requirements.  The risk-based capital ratio of The Citizens National
Bank of Slatington also exceed regulatory requirements at September 30, 1998.

                                   September 30,            December 31,

Results of Operations

     Consolidated net income for the first nine months of 1998 was $706,000,  or
4.7% below the first nine months of 1997.  Basic and diluted  earnings per share
for the first nine months of 1998 were $5.06 and $4.97, respectively.  The Basic
and diluted earnings per share for the same period in 1997 were $5.41 and $5.34,
respectively.  The  decrease  in net  income is the  result of higher  operating
expenses  experienced  during 1998. The December 31, 1997 net income of $980,000
was 14.1%  higher than the  December  31,  1996 net income of $859,000  and 5.3%
higher than the December 31, 1995 net income of $931,000.

     On  January 1, 1998,  Northern  Lehigh  adopted  the  Financial  Accounting
Standards Board issued  Statement of Financial  Accounting  Standards (SFAS) No.
130, "Reporting  Comprehensive  Income."  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 on investment  securities  available for sale.
Subsequent to the adoption  date,  all  prior-period  amounts are required to be
restated to conform to the provision of SFAS No. 130.  Comprehensive  income for
the first nine months of 1998 was  $712,000,  compared to $742,000 for the first
nine months of 1997.  Comprehensive  income for December 31, 1997, 1996 and 1995
was $986,000, $831,000 and $1,019,000, respectively.

Net Interest Income

     Net interest  income at September  30, 1998 of  $2,586,000  was 3.6% higher
than the September 30, 1998 net interest income of $2,495,000. This increase was
the result of a 6.1% increase in earning  assets  during this period.  Partially
offsetting  this increase was a reduction in the net interest  margin during the
first nine months of 1998, compared to the same period in 1997. The net interest
margin  for the  first  nine  months  of 1998  and  1997 was  4.99%  and  5.13%,
respectively.  This  reduction  in the  net  interest  margin  was due to both a
decrease in the yield on average  earning assets and an increase in the interest
rate paid on average deposits and borrowings.

     Net interest  income at December 31, 1997 of $3,390,000 was higher than the
December 31, 1996 and 1995 net interest  income of  $3,073,000  and  $2,989,000,
respectively.  The net  interest  margin  for  the  twelve-month  period  ending
December  31, 1997 of 5.41% was higher  than the 4.96% at December  31, 1996 and
the 5.10% at December 31, 1995.

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%.

Provision for Loan Losses

     The  provision  for loan  losses  for the  first  nine  months  of 1998 was
$75,000,  compared to $60,000 for the same period in 1997. The Citizens National
Bank of  Slatington  experienced a $1,000 net recovery of loans during the first
nine  months of 1998,  compared  to a net  recovery  of $58,000  during the same
period in 1997.  The provision  for loan losses for the year ended  December 31,
1997, 1996 and 1995 were $90,000, $115,000 and $70,000, respectively.

Other Income

     Other income grew 7.1% from $183,000  during the first nine months of 1997,
to $196,000  during the same period in 1998.  The increase was  primarily due to
both higher  credit card fees and ATM  surcharges.  Other  income for the entire
year of 1997 of  $200,000  was  $4,000  higher  than the 1996  other  income  of
$196,000,  and  $100,000  lower than the 1995 other  income of  $300,000.  Other
income in 1995 included two  non-recurring  items that amounted to approximately
$140,000.

Other Operating Expenses

     Other  operating  expenses of $1,687,000 for the first nine months of 1998,
was $131,000  higher than the same period in 1997.  This increase was the result
of higher salaries,  wages and employee benefits and other expenses. The rise in
other  expenses was due to an increase in expenses  related to other real estate
owned, advertising and supplies. Other operating expenses for the entire year of
1997 of  $2,097,000,  was $121,000  and $49,000  higher than the same periods in
1996 and 1995, respectively.

                  NORTHERN LEHIGH BANCORP, INC. AND SUBSIDIARY
                   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 consolidated  financial
position  of  Northern  Lehigh  Bancorp,   Inc.  (the   "Corporation")  and  its
wholly-owned  subsidiary - The Citizens National Bank of Slatington (the "Bank")
- - as of September  30, 1998,  the results of its  operations  for the nine month
periods ended  September 30, 1998 and 1997 and the cash flows for the nine month
periods ended  September 30, 1998 and 1997. It is suggested that these unaudited
consolidated  financial  statements  be read in  conjunction  with  the  audited
consolidated  financial  statements of the Corporation and the notes thereto set
forth in the Corporation's 1997 annual report.

The results of operations  for the nine month  periods ended  September 30, 1998
and 1997 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 and loans.

Note 3 - During 1997,  the  Corporation  adopted the provisions of the Financial
Accounting  Standards Board issued Statement of Financial  Accounting  Standards
(SFAS) No. 128,  "Earnings per Share." SFAS No. 128 eliminates primary and fully
diluted  earnings  per  share and  requires  presentation  of basic and  diluted
earnings per share (EPS) in conjunction  with the disclosure of the  methodology
used in computing  such  earnings per share.  Basic  earnings per share  exclude
dilution and are computed by dividing income available to common shareholders by
the  weighted-average  common  shares  outstanding  during the  period.  Diluted
earnings per share take into account the potential  dilution that could occur if
securities or other contracts to issue common stock were exercised and converted
into common stock.  Prior  periods'  earnings per share  calculations  have been
restated to reflect the adoption of SFAS No. 128.

Note 4 - On June 2, 1997, the  Corporation  distributed  12,672 shares of common
stock  in  connection  with a 10%  stock  dividend.  As a  result  of the  stock
dividend, common stock was increased by $126,720, additional paid-in capital was
increased $506,880, and retained earnings was decreased by $633,600.

Note 5 - On January 1, 1998, the  Corporation  adopted the Financial  Accounting
Standards  Board  issued  SFAS No. 129,  Disclosure  Information  about  Capital
Structure.  SFAS  No.  129  summarizes  previously  issued  disclosure  guidance
contained  within  APB  Opinion  No.  10 and 15,  as well as SFAS  No.  47.  The
Corporation's  current disclosures were not affected by the adoption of SFAS No.
129.

Note 6 - On January 1, 1998, the  Corporation  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

                                      -87-

<PAGE>


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 on investment  securities  available for
sale.  Subsequent to the adoption date, all priorperiod  amounts are required to
be restated to conform to the  provision of SFAS No. 130.  Comprehensive  income
for the first nine months of 1998 was  $712,000,  compared  to $742,000  for the
first nine months of 1997.  Comprehensive income for December 31, 1997, 1996 and
1995 was $987,000, $831,000 and $1,018,000,  respectively.  The adoption of SFAS
No. 130 did not have a material impact on the Corporation's  financial  position
or results of operation.

Note 7 - 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.  The adoption
of SFAS No. 131 did not have an impact on the Corporation's  financial  position
or results of operation.

Note 8 - The American Institute of Certified Public  Accountants  (AICPA) issued
Statement of Position (SOP) 98-1 "Accounting for the Costs of Computer  Software
Developed  or  Obtained  for  Internal  Use."  The SOP  was  issued  to  provide
authoritative  guidance on the subject of  accounting  for the costs  associated
with the  purchase  or  development  of  computer  software.  The  statement  is
effective for fiscal years  beginning after December 15, 1998. This statement is
not expected to have a material impact on the Corporation's  financial  position
or results of operations.

Note 9 - 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 or losses)  depends on the intended use of the derivative and
resulting  designation.  SFAS No. 133 is  effective  for all fiscal  quarters of
fiscal years  beginning  after June 15, 1999.  Earlier  application is permitted
only as of the  beginning  of any  fiscal  quarter.  The  company  is  currently
reviewing the provisions of SFAS No.133.

                          INDEPENDENT AUDITOR'S REPORT


Board of Directors
Northern Lehigh Bancorp, Inc.
Slatington, Pennsylvania

We have audited the accompanying  consolidated balance sheets of Northern Lehigh
Bancorp,  Inc. and  subsidiary as of December 31, 1997 and 1996, and the related
consolidated  statements of income,  changes in shareholders'  equity,  and cash
flows for the years then ended. These consolidated  financial statements are the
responsibility of the Corporation's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all material  respects,  the financial  position of Northern  Lehigh
Bancorp,  Inc. and  subsidiary as of December 31, 1997 and 1996, and the results
of their operations and their cash flows for the years then ended, in conformity
with generally accepted accounting principles.

                     YEARS ENDED DECEMBER 31, 1997 AND 1996

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     General:

     The accompanying  consolidated financial statements include the accounts of
     Northern  Lehigh  Bancorp,  Inc. (the  "Corporation")  and its wholly owned
     subsidiary,  The Citizens  National  Bank of Slatington  (the "Bank").  All
     material intercompany transactions have been eliminated.

     The following summary of accounting and reporting  policies is presented to
     aid the  reader  in  obtaining  a  better  understanding  of the  financial
     statements  and  related  financial  data of the  Corporation  and the Bank
     contained  in this report.  Such  policies  conform to  generally  accepted
     accounting  principles  ("GAAP") and to general practice within the banking
     industry.  In  preparing  financial  statements  in  conformity  with GAAP,
     management is required to make  estimates and  assumptions  that affect the
     reported amounts of assets and liabilities and the disclosure of contingent
     assets and  liabilities at the date of the financial  statements and income
     and expenses during the reporting period.  Actual results could differ from
     those estimates.

     Certain items of the consolidated financial statements,  as of December 31,
     1996,  have  been  reclassified  to  conform  with the  December  31,  1997
     presentation. None of these reclassifications affected net income.

     Securities:

     The Corporation has adopted Statement of Financial Accounting Standards No.
     115,  "Accounting for Certain  Investments in Debt and Equity  Securities."
     This statement  addresses the  accounting and reporting for  investments in
     equity  securities that have readily  determinable  fair values and for all
     investments in debt securities.  Those  investments are to be classified in
     three  categories  and  accounted  for as follows  (a)  securities  held to
     maturity, (b) trading securities and (c) securities available for sale.

     Debt securities that the Corporation has the positive intent and ability to
     hold to maturity  are  classified  as  securities  held to maturity and are
     reported at amortized cost. Debt and equity  securities that are bought and
     held  principally  for the  purpose  of  selling  them in the near term are
     classified  as  trading   securities  and  reported  at  fair  value,  with
     unrealized  gains  and  losses  included  in  earnings.   Debt  and  equity
     securities not classified as either held to maturity  securities or trading
     securities are classified as securities available for sale and are reported
     at fair value,  with unrealized gains and losses excluded from earnings and
     reported as a separate component of shareholders' equity.

                     YEARS ENDED DECEMBER 31, 1997 AND 1996

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Securities (Continued):

     Net gain or loss on the sale of securities is determined using the specific
     identification method.

     Loans:

     Loans are stated at the principal amount  outstanding.  When a loan becomes
     past due and doubt exists as to the ultimate  collection  of principal  and
     interest,  the accrual of income is discontinued  and is only recognized at
     the time payment is received.

     The Corporation has adopted Financial  Accounting Standards Board Statement
     No. 114  "Accounting by Creditors for Impairment of a Loan" ("FAS 114"), as
     amended by Statement No. 118  "Accounting  By Creditors for Impairment of a
     Loan Income  Recognition and  Disclosures",  ("FAS 118").  These statements
     address the accounting by creditors,  such as banks,  for the impairment of
     certain loans. The Corporation  considers a loan to be impaired when, based
     on current information and events, it is probable that the Corporation will
     be unable to collect principal or interest due according to the contractual
     terms of the loan.  Loan  impairment is measured based on the present value
     of expected cash flows discounted at the loan's effective interest rate or,
     as a practical expedient,  at the loans observable market price or the fair
     value of the collateral if the loan is collateral dependent.

     Payment  received  on  impaired  loans are  applied  against  the  recorded
     investment  in the loan.  For loans  other than those that the  Corporation
     expects repayment through liquidation of the collateral, when the remaining
     recorded  investment  in the  impaired  loan is less  than or  equal to the
     present  value of the  expected  cash  flows,  income is recorded on a cash
     basis.

     Loan Origination Fees and Costs:

     The net fees and costs  directly  related to the  origination of a loan are
     deferred and  amortized  over the life of the loan as an  adjustment of the
     loan yield.

     Other Real Estate Owned:

     Real estate, other than bank premises,  is recorded at the lower of cost or
     market  at the  time  of  acquisition.  Expenses  related  to  holding  the
     property,  net of rental income,  are generally charged against earnings in
     the current period.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1997 AND 1996

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Allowance for Loan Losses:

     The allowance for loan losses represents management's estimate of an amount
     adequate  to provide for losses  which may be  incurred on loans  currently
     held.  Management determines the adequacy of the allowance based on reviews
     of  individual  credits,   historical  patterns  of  loan  charge-offs  and
     recoveries, industry experience, current economic trends, and other factors
     relevant to the collectibility of the loans currently in the portfolio. The
     allowance  is  increased by  provisions  charged to  operating  expense and
     reduced by net charge-offs.

     Premises and Equipment:

     Premises and  equipment are carried at cost less  accumulated  depreciation
     and  amortization.   For  financial  statement  reporting  and  income  tax
     purposes,   depreciation  is  computed  both  on  the   straight-line   and
     accelerated  methods  over the  estimated  useful lives of the premises and
     equipment. Charges for maintenance and repairs are expensed as incurred.

     Income Taxes:

     Certain  income and expense items are accounted for in different  years for
     financial  reporting purposes than for income tax purposes.  Deferred taxes
     are provided to recognize these temporary differences.  The principal items
     involved are discount accretion on securities,  provision for possible loan
     losses and accrued  benefits.  Income tax expense is not  proportionate  to
     earnings  before taxes,  principally  because  income from  obligations  of
     states and political subdivisions is nontaxable.

     Earnings per Share:

     Earnings  per  common  share  have been  computed  based upon the number of
     weighted  average  number of shares  outstanding  during each of the years.
     Stock options granted were not considered in the computation  because their
     effect was not  material.  The  weighted  average  shares  outstanding  was
     140,011  for 1997  and  141,348  for  1996.  The  weighted  average  shares
     outstanding for 1996 has been adjusted for a 10% stock dividend declared in
     April 1997.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Earnings per Share (Continued):

     In February 1997, the Financial Accounting Standards Board issued Statement
     of  Financial  Accounting  Standards  No. 128,  "Earnings  Per Share" ("FAS
     128").  This statement  redefines the standards for computing  earnings per
     share (EPS) previously found in Accounting Principles board opinion No. 15,
     "Earnings Per Share." FAS 128  establishes  new standards for computing and
     presenting EPS and requires dual  presentation of "basic" and "diluted" EPS
     on the face of income  statement  for all  entities  with  complex  capital
     structures.  Under FAS 128,  basic EPS is to be computed  based upon income
     available to common  shareholders and the weighted average number of common
     shares outstanding for the period.  Diluted EPS is to reflect the potential
     dilution  exercised  or  converted  into  common  stock or  resulted in the
     issuance  of  common  stock  that  then  shared  in  the  earnings  of  the
     Corporation.  FAS 128 also requires the restatement of all prior-period EPS
     data presented.

     Comprehensive Income:

     On  January 1, 1998,  the  Corporation  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 on investment  securities  available for
     sale.  Subsequent  to the  adoption  date,  all  prior-period  amounts  are
     required  to be  restated  to conform  to the  provision  of SFAS No.  130.
     Comprehensive  income  for  December  31,  1997 and 1996 was  $987,000  and
     $831,000,  respectively.  The  adoption  of SFAS  No.  130  did not  have a
     material  impact on the  Corporation's  financial  position  or  results of
     operation.

     Employee Benefit Plan:

     The Bank has a non-contributory  defined contribution pension plan covering
     all employees  over 21 years of age and having at least one year of service
     (Note 9).

     The Bank also has a deferred  compensation plan involving  directors of the
     Bank. The plan requires  defined annual payments for ten years beginning at
     age 65 or death.  The annual benefit is based upon the amount deferred plus
     interest. The present value of these deferred compensation  liabilities was
     approximately  $207,177  and  $183,588  at  December  31,  1997  and  1996,
     respectively.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Employee Benefit Plan (Continued):

     In October 1995 the Financial  Accounting  Standards Board issued Statement
     of Financial  Accounting  Standards  No. 123  "Accounting  for  Stock-Based
     Compensation"  ("FAS 123").  This new  standard  defines a fair value based
     method  of  accounting  for an  employee  stock  option or  similar  equity
     instrument.  This statement gives entities a choice of recognizing  related
     compensation  expense by adopting  the new fair value method or to continue
     to measure compensation using the intrinsic value approach under Accounting
     Principles Board (APB) Opinion No. 25, the former standard.

     The Corporation has elected,  as permitted by FAS 123, to apply APB Opinion
     25 and related Interpretations in accounting for its plan. Accordingly,  no
     compensation  cost has been  recognized for its stock options  outstanding.
     Had  compensation  cost  for  the  Corporation's  stock  option  plan  been
     determined  based upon the fair value at the grant  dates for awards  under
     the  plan  consistent  with  the  method  of FAS  123,  the  effect  on the
     Corporation's net income and earnings per share would not be material.

     Cash and Cash Equivalents:

     For purposes of reporting cash flows,  the Corporation has defined cash and
     cash  equivalents  as those amounts  included in the balance sheet captions
     "Cash and cash equivalents" and "Federal funds sold."

2.   CASH AND DUE FROM BANKS

     Regulations of the Board of Governors of the Federal  Reserve System impose
     uniform   reserve   requirements  on  all  depository   institutions   with
     transaction accounts (checking accounts, NOW accounts,  etc.). Reserves are
     maintained in the form of vault cash or a non-interest bearing balance held
     with the Federal Reserve Bank. The Bank also, from time to time,  maintains
     deposits with the Federal Reserve Bank and other banks for various services
     such as check  clearing.  The Bank's reserve  requirement  was $285,000 and
     $269,000 at December 31, 1997 and 1996, respectively.

     Impairment  of  loans  having   recorded   investments  of  $2,145,594  and
     $1,927,506 at December 31, 1997 and 1996 has been  recognized in conformity
     with FAS 114 as amended by FAS 188.  The  average  recorded  investment  in
     impaired  loans  during  1997  and  1996  was  $2,408,336  and  $1,989,623,
     respectively. There was no allowance for loan losses related to these loans

6.   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

     The Corporation 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  standby  letters  of credit.  These  instruments  involve,  to varying
     degrees,  elements of credit and interest rate risk in excess of the amount
     recognized in the balance sheet.  The contract or notional amounts of these
     instruments  reflect  the  extent of  involvement  the  Corporation  has in
     particular classes of financial instruments. The Corporation does not issue
     any other instruments with significant off-balance-sheet risk.

     The Corporation's exposure to credit loss in the event of nonperformance by
     the other  party to the  financial  instrument  for  commitments  to extend
     credit and standby letters of credit written is represented by the contract
     or notional  amount of those  instruments.  The  Corporation  uses the same
     credit policies in making  commitments  and  conditional  obligations as it
     does for  on-balancesheet  instruments.  The following table identifies the
     contract or notional amount of those instruments at December 31,:

6.   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK (CONTINUED)

                                                   1997              1996
                                                   ----              ----
    Financial instruments whose contract
     amounts represent credit risk:
        Commitments to extend credit            $7,163,272        $8,691,684
        Standby letters of credit               $  674,243        $  609,327


     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.
     Commitments  generally  have fixed  expiration  dates or other  termination
     clauses and may require payment of a fee. Since many of the commitments are
     expected to expire without being drawn upon, the total  commitment  amounts
     do not  necessarily  represent  future cash  requirements.  The Corporation
     evaluates each customer's  credit  worthiness on a case-by-case  basis. The
     amount of collateral  obtained if deemed  necessary by the Corporation upon
     extension  of  credit is based on  management's  credit  evaluation  of the
     counter party.  Collateral held varies but may include accounts receivable,
     inventory,  property, plant, and equipment, and income-producing commercial
     properties.

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

9.   PENSION PLAN

     The Bank has a  non-contributory  defined benefit pension plan covering all
     employees over 21 years of age and having at least one year of service. The
     plan calls for  benefits to be paid to  eligible  employees  at  retirement
     based primarily upon years of service with the Bank and compensation  rates
     near retirement.  Contributions to the plan reflect benefits  attributed to
     employees'  services to date, as well as services  expected to be earned in
     the future.  Plan assets consist of primarily  common and preferred  stock,
     investment-grade  corporate bonds,  and U.S.  government  obligations.  The
     following  table sets forth the plan's  funded  status at  December  31, as
     follows:

10.  STOCK OPTION PLANS

     On July 26, 1989, the  Corporation  adopted an Incentive  Stock Option Plan
     whereby,  the Corporation  entered into Incentive  Stock Option  Agreements
     with an officer of the Bank.  The maximum  number of shares of common stock
     that may be  optioned or sold under the Plan is 5,000  shares.  The options
     may be exercised at any time from the period commencing one year and ending
     ten years from the date of the agreements.  The options expire beginning in
     1999 through 2004. The  Corporation  had 5,000 shares of outstanding  stock
     options  at  December  31,  1997 and 1996,  respectively,  with a  weighted
     average  exercise price of $34.87 per share.  There were no shares granted,
     exercised, or forfeited in 1997 or 1996.

     $267,104  and  $226,011 at December  31, 1997 and 1996,  respectively.  The
     Corporation has not established a valuation allowance as it is management's
     belief that it has adequate  taxable  income and  carrybacks to realize the
     net deferred  tax asset.  The  components  of the net deferred tax asset at
     December 31, 1997 and 1996 are as follows:

15.  DIVIDEND RESTRICTIONS

     The  amount of funds  available  to a parent  from its  subsidiary  bank is
     limited for all national banks by  restrictions  imposed by the Comptroller
     of the Currency.  At December 31, 1997,  dividends  were  restricted not to
     exceed $2,657,197. These restrictions have not had, and are not expected to
     have, a significant  impact on the  Corporation's  ability to meet its cash
     obligations.

16.  RELATED PARTY TRANSACTIONS

     Some of the  Corporation's  or its Bank's  directors,  principal  officers,
     principal  shareholders,  and their related interests had transactions with
     the Bank in the  ordinary  course of business  during  1997.  All loans and
     commitments to loans in such  transactions  were made on substantially  the
     same terms, including collateral and interest rates, as those prevailing at
     the time for comparable transactions.  In the opinion of management,  these
     transactions  do not involve  more than normal  risk of  collectibility  or
     present other  unfavorable  features.  It is anticipated  that further such
     extensions of credit will be made in the future.

     The aggregate  amount of credit  extended to these  directors and principal
     officers  was  $1,137,358  and  $1,052,972  at December  31, 1997 and 1996,
     respectively.

     The following is an analysis of loans to these parties during 1997:

       Balances at January 1, 1997                          $1,052,972

17.  CAPITAL REQUIREMENTS

     The  Corporation  and the Bank are  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  consolidated  financial  statements.
     Under capital adequacy  guidelines and the regulatory  framework for prompt
     corrective  action, the Corporation and the Bank must meet specific capital
     guidelines that involve quantitative  measures of the assets,  liabilities,
     and  certain   off-balance-sheet   items  as  calculated  under  regulatory
     accounting  practices.  The  capital  amounts and  classification  are also
     subject to qualitative  judgments by the regulators about components,  risk
     weighting, and other factors.

     Quantitative  measures established by regulation to ensure capital adequacy
     require  the  maintenance  of minimum  amounts of ratios  (set forth in the
     tables  below) of total and Tier I capital (as defined in the  regulations)
     to risk-weighted assets (as defined).  Management believes,  as of December
     31,  1997,  that the  Corporation  and the Bank meet all  capital  adequacy
     requirements to which they are subject.

     As of December 31, 1997 the most recent  notification  from the  regulatory
     agencies categorized the Corporation and the Bank as well capitalized under
     the regulatory framework for prompt corrective action. To be categorized as
     well capitalized,  the Corporation and 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 those notifications that
     management believes have changed those categories.

                          INDEPENDENT AUDITOR'S REPORT


Board of Directors
Northern Lehigh Bancorp, Inc.
Slatington, Pennsylvania


We have audited the accompanying  consolidated balance sheets of Northern Lehigh
Bancorp,  Inc. and  subsidiary as of December 31, 1996 and 1995, and the related
consolidated  statements of income,  changes in shareholders'  equity,  and cash
flows for the years then ended. These consolidated  financial statements are the
responsibility of the Corporation's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all material  respects,  the financial  position of Northern  Lehigh
Bancorp,  Inc. and  subsidiary as of December 31, 1996 and 1995, and the results
of their operations and their cash flows for the years then ended, in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1996 AND 1995


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     General:

     The accompanying  consolidated financial statements include the accounts of
     Northern  Lehigh  Bancorp,  Inc. (the  "Corporation")  and its wholly owned
     subsidiary,  The Citizens  National  Bank of Slatington  (the "Bank").  All
     material intercompany transactions have been eliminated.

     The following summary of accounting and reporting  policies is presented to
     aid the  reader  in  obtaining  a  better  understanding  of the  financial
     statements  and  related  financial  data of the  Corporation  and the Bank
     contained  in this report.  Such  policies  conform to  generally  accepted
     accounting  principles  ("GAAP") and to general practice within the banking
     industry.  In  preparing  financial  statements  in  conformity  with GAAP,
     management is required to make  estimates and  assumptions  that affect the
     reported amounts of assets and liabilities and the disclosure of contingent
     assets and  liabilities at the date of the financial  statements and income
     and expenses during the reporting period.  Actual results could differ from
     those estimates.

     Certain items of the consolidated financial statements,  as of December 31,
     1995,  have  been  reclassified  to  conform  with the  December  31,  1996
     presentation. None of these reclassifications affected net income.

     Securities:

     In May 1993, the Financial  Accounting  Standards Board issued Statement of
     Financial  Accounting  Standards No. 115 ("FAS No. 115"),  "Accounting  for
     Certain   Investments  in  Debt  and  Equity  Securities."  This  statement
     addresses the accounting and reporting for investments in equity securities
     that have readily  determinable fair values and for all investments in debt
     securities.  Those investments are to be classified in three categories and
     accounted  for as follows  (a)  securities  held to  maturity,  (b) trading
     securities and (c) securities available for sale.

     Debt securities that the Corporation has the positive intent and ability to
     hold to maturity  are  classified  as  securities  held to maturity and are
     reported at amortized cost. Debt and equity  securities that are bought and
     held  principally  for the  purpose  of  selling  them in the near term are
     classified  as  trading   securities  and  reported  at  fair  value,  with
     unrealized  gains  and  losses  included  in  earnings.   Debt  and  equity
     securities not classified as either held to maturity  securities or trading
     securities are classified as securities available for sale and are reported
     at fair value,  with unrealized gains and losses excluded from earnings and
     reported as a separate component of shareholders' equity.

     Loans:

     Loans are stated at the principal amount  outstanding.  When a loan becomes
     past due and doubt exists as to the ultimate  collection  of principal  and
     interest,  the accrual of income is discontinued  and is only recognized at
     the time payment is received.

     Loan Origination Fees and Costs:

     The net fees and costs  directly  related to the  origination of a loan are
     deferred and  amortized  over the life of the loan as an  adjustment of the
     loan yield.

     Other Real Estate Owned:

     Real estate, other than bank premises,  is recorded at the lower of cost or
     market  at the  time  of  acquisition.  Expenses  related  to  holding  the
     property,  net of rental income,  are generally charged against earnings in
     the current period.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Reserve for Possible Loan Losses:

     The reserve for possible loan losses represents management's estimate of an
     amount  adequate  to provide  for  losses  which may be  incurred  on loans
     currently held.  Management determines the adequacy of the reserve based on
     reviews of individual credits,  historical patterns of loan charge-offs and
     recoveries, industry experience, current economic trends, and other factors
     relevant to the collectibility of the loans currently in the portfolio. The
     reserve is increased by provisions charged to operating expense and reduced
     by net charge-offs.

     Premises and Equipment:

     Premises and  equipment are carried at cost less  accumulated  depreciation
     and  amortization.   For  financial  statement  reporting  and  income  tax
     purposes,   depreciation  is  computed  both  on  the   straight-line   and
     accelerated  methods  over the  estimated  useful lives of the premises and
     equipment. Charges for maintenance and repairs are expensed as incurred.

     Income Taxes:

     Certain  income and expense items are accounted for in different  years for
     financial  reporting purposes than for income tax purposes.  Deferred taxes
     are provided to recognize these temporary differences.  The principal items
     involved are discount accretion on securities,  provision for possible loan
     losses and accrued  benefits.  Income tax expense is not  proportionate  to
     earnings  before taxes,  principally  because  income from  obligations  of
     states and political subdivisions is nontaxable.

     Earnings per Share:

     During  1997,  the  Corporation  adopted the  provisions  of the  Financial
     Accounting   Standards  Board  issued  Statement  of  Financial  Accounting
     Standards  (SFAS) No. 128,  "Earnings  per Share." SFAS No. 128  eliminates
     primary and fully diluted  earnings per share and requires  presentation of
     basic  and  diluted  earnings  per  share  (EPS)  in  conjunction  with the
     disclosure of the  methodology  used in computing  such earnings per share.
     Basic  earnings  per share  exclude  dilution  and are computed by dividing
     income  available to common  shareholders  by the  weighted-average  common
     shares outstanding during the period.  Diluted earnings per share take into
     account the  potential  dilution  that could occur if  securities  or other
     contracts to issue common stock were  exercised and  converted  into common
     stock. Prior periods' earnings per share calculations have been restated to
     reflect the adoption of SFAS No. 128.

     Comprehensive Income:

     On  January 1, 1998,  the  Corporation  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 on investment  securities  available for
     sale.  Subsequent  to the  adoption  date,  all  prior-period  amounts  are
     required  to be  restated  to conform  to the  provision  of SFAS No.  130.
     Comprehensive  income  for  December  31,  1996 and 1995 was  $831,000  and
     $1,018,000,  respectively.  The  adoption  of SFAS  No.  130 did not have a
     material  impact on the  Corporation's  financial  position  or  results of
     operation.

     Employee Benefit Plan:

     The Bank has a non-contributory  defined contribution pension plan covering
     all employees  over 21 years of age and having at least one year of service
     (Note 9).

     The Bank also has a deferred  compensation plan involving  directors of the
     Bank. The plan requires  defined annual payments for ten years beginning at
     age 65 or death.  The annual benefit is based upon the amount deferred plus
     interest. The present value of these deferred compensation  liabilities was
     approximately  $183,588  and  $162,702  at  December  31,  1996  and  1995,
     respectively.

     Cash and Cash Equivalents:

     For purposes of reporting cash flows,  the Corporation has defined cash and
     cash  equivalents  as those amounts  included in the balance sheet captions
     "Cash and cash equivalents" and "Federal funds sold."

2.   CASH AND DUE FROM BANKS

     Regulations of the Board of Governors of the Federal  Reserve System impose
     uniform   reserve   requirements  on  all  depository   institutions   with
     transaction accounts (checking accounts, NOW accounts,  etc.). Reserves are
     maintained in the form of vault cash or a non-interest bearing balance held
     with the Federal Reserve Bank. The Bank also, from time to time,  maintains
     deposits with the Federal Reserve Bank and other banks for various services
     such as check  clearing.  The Bank's reserve  requirement  was $269,000 and
     $316,000 at December 31, 1996 and 1995, respectively.

Included in equity  securities  are Federal  Reserve Bank and  Atlantic  Central
Bankers Bank stock in the amount of $34,000 at December 31, 1996 and 1995.

Gross gains of $0 and $294 were  realized on calls and  maturities of securities
in 1996 and 1995,  respectively.  In November  1995,  the  Financial  Accounting
Standards Board issued a special report "A Guide to Implementation of FAS 115 on
Accounting for Certain Investments in Debt and Equity Securities - Questions and
Answers." As permitted by the Guide,  the Bank  transferred  securities from the
held to maturity  classification  to the  available for sale  classification  in
November 1995. The amortized cost of these securities as of the date of transfer
was $175,000 with a fair market value of $150,000.

5.   RESERVE FOR POSSIBLE LOAN LOSSES (CONTINUED)

     In May 1993, the Financial  Accounting Standards Board issued Statement No.
     114  "Accounting  by Creditors for  Impairment of a Loan" ("FAS 114") which
     was amended in October 1994 by Statement No. 118  "Accounting  by Creditors
     for Impairment of a Loan - Income  Recognition and Disclosures" ("FAS 118")
     which  addresses the  disclosure of certain loans where it is probable that
     the  creditor  will be unable to collect all amounts due  according  to the
     contractual terms of the loan agreement. Additionally, FAS 118 requires the
     disclosure of how the creditor  recognizes interest income related to these
     impaired  loans.  The  Corporation  adopted FAS 114, as amended by FAS 118,
     beginning January 1, 1995. The effect of adoption was not material.

     Impairment  of  loans  having   recorded   investments  of  $1,927,506  and
     $1,230,868 at December 31, 1996 and 1995 has been  recognized in conformity
     with FAS 114 as amended by FAS 118.  The  average  recorded  investment  in
     impaired  loans  during  1996  and  1995  was  $1,989,623  and  $1,247,324,
     respectively.  The total reserve for loan losses related to these loans was
     $0 at  December  31,  1996 and 1995,  respectively.  Additions  charged  to
     expense for the reserve for impaired  loans amounted to $60,000 and $41,458
     in 1996 and 1995. Direct  write-downs  charged against the reserve amounted
     to $60,000 and $51,458 in 1996 and 1995.  Interest income on impaired loans
     of $44,774 and $33,295 was  recognized  for cash payments  received in 1996
     and 1995.

6.   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

     The Corporation 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  standby  letters  of credit.  These  instruments  involve,  to varying
     degrees,  elements of credit and interest rate risk in excess of the amount
     recognized in the balance sheet.  The contract or notional amounts of these
     instruments  reflect  the  extent of  involvement  the  Corporation  has in
     particular classes of financial instruments. The Corporation does not issue
     any other instruments with significant off-balance-sheet risk.

     The Corporation's exposure to credit loss in the event of nonperformance by
     the other  party to the  financial  instrument  for  commitments  to extend
     credit and standby letters of credit written is represented by the contract
     or notional  amount of those  instruments.  The  Corporation  uses the same
     credit policies in making  commitments  and  conditional  obligations as it
     does for on-balance-sheet  instruments.  The following table identifies the
     contract or notional amount of those instruments at December 31,:

                                                         ------        -----
      Financial instruments whose contract amounts
       represent credit risk:
         Commitments to extend credit                 $8,691,684    $5,409,799
         Standby letters of credit                    $  609,327    $  767,988


     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.
     Commitments  generally  have fixed  expiration  dates or other  termination
     clauses and may require payment of a fee. Since many of the commitments are
     expected to expire without being drawn upon, the total  commitment  amounts
     do not  necessarily  represent  future cash  requirements.  The Corporation
     evaluates each customer's  credit  worthiness on a case-by-case  basis. The
     amount of collateral  obtained if deemed  necessary by the Corporation upon
     extension  of  credit is based on  management's  credit  evaluation  of the
     counterparty.  Collateral held varies but may include accounts  receivable,
     inventory,  property, plant, and equipment, and income-producing commercial
     properties.

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


7.   PREMISES AND EQUIPMENT

     The  depreciation  provision  charged  to  operating  expense  amounted  to
     $104,664 in 1996,  and $96,101 in 1995.  The  composition  of premises  and
     equipment at December 31, is as follows:

9.   PENSION PLAN

     The Bank has a  non-contributory  defined benefit pension plan covering all
     employees over 21 years of age and having at least one year of service. The
     plan calls for  benefits to be paid to  eligible  employees  at  retirement
     based primarily upon years of service with the Bank and compensation  rates
     near retirement.  Contributions to the plan reflect benefits  attributed to
     employees'  services to date, as well as services  expected to be earned in
     the future.  Plan assets consist of primarily  common and preferred  stock,
     investment-grade  corporate bonds,  and U.S.  government  obligations.  The
     following  table sets forth the plan's  funded  status at  December  31, as
     follows:

10.  STOCK OPTION PLANS

     In October 1995 the Financial  Accounting  Standards Board issued Statement
     of  Financial   Accounting   Standards   (SFAS)  No.  123  "Accounting  for
     Stock-Based  Compensation."  This new  standard  defines a fair value based
     method  of  accounting  for an  employee  stock  option or  similar  equity
     instrument.  This statement gives entities a choice of recognizing  related
     compensation  expense by adopting  the new fair value method or to continue
     to measure compensation using the intrinsic value approach under Accounting
     Principles Board (APB) Opinion No. 25, the former standard.

     On July 26, 1989, the  Corporation  adopted an Incentive  Stock Option Plan
     whereby,  the Corporation  entered into Incentive  Stock Option  Agreements
     with an officer of the Bank.  The maximum  number of shares of common stock
     that may be  optioned or sold under the Plan is 5,000  shares.  The options
     may be exercised at any time from the period commencing one year and ending
     ten years from the date of the agreements.

     The Corporation  has elected,  as permitted by FASB Statement 123, to apply
     APB  Opinion 25 and related  Interpretations  in  accounting  for its plan.
     Accordingly, no compensation cost has been recognized for its stock options
     outstanding.  Had compensation cost for the Corporation's stock option plan
     been  determined  based upon the fair  value at the grant  dates for awards
     under the plan  consistent  with the method of SFAS No. 123,  the effect on
     the Corporation's net income and earnings per share would not be material.

     A summary of the status of the  Corporation's  outstanding stock options as
     of  December  31,  1996 and  changes  for the year  ending  on that date is
     presented below:

11.  EMPLOYEE STOCK OWNERSHIP PLAN

     The Corporation  established an Employee Stock Ownership Plan in 1985 which
     allows  all  qualified   employees  to  invest  plan  assets  primarily  in
     securities of the Corporation. In 1995, this plan was formally dissolved.

14.  STOCK DIVIDEND

     On June 2, 1997, the Corporation  distributed 12,672 shares of common stock
     in connection with 10% stock  dividend.  As a result of the stock dividend,
     common  stock was  increased by $126,720,  additional  paid-in  capital was
     increased by $506,880, and retained earnings was decreased by $633,600. All
     references in the accompanying consolidated financial statements to the per
     share  amounts  for 1996 and 1995 have been  restated  to reflect the stock
     dividend.

15.  CONTINGENCIES AND COMMITMENTS

     There are no legal  proceedings to which the  Corporation or the Bank are a
     party, except proceedings which arise in the normal course of business and,
     in the  opinion of  management,  will not have any  material  effect on the
     consolidated financial position of the Corporation and the Bank.

16.  CONTINGENCIES AND COMMITMENTS

     There are no legal  proceedings to which the  Corporation or the Bank are a
     party, except proceedings which arise in the normal course of business and,
     in the  opinion of  management,  will not have any  material  effect on the
     consolidated financial position of the Corporation and the Bank.

17.  RELATED PARTY TRANSACTIONS

     Some of the  Corporation's  or its Bank's  directors,  principal  officers,
     principal  shareholders,  and their related interests had transactions with
     the Bank in the  ordinary  course of business  during  1996.  All loans and
     commitments to loans in such  transactions  were made on substantially  the
     same terms, including collateral and interest rates, as those prevailing at
     the time for comparable transactions.  In the opinion of management,  these
     transactions  do not involve  more than normal  risk of  collectibility  or
     present other  unfavorable  features.  It is anticipated  that further such
     extensions of credit will be made in the future.

     The aggregate  amount of credit  extended to these  directors and principal
     officers  was  $1,052,972  and  $1,072,751  at December  31, 1996 and 1995,
     respectively.

     The following is an analysis of loans to these parties during 1996:

          Balances at January 1, 1996               $1,072,751
          Advances                                      80,000

                                                    ==========

18.  CAPITAL REQUIREMENTS

     The  Corporation  and the Bank are  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  consolidated  financial  statements.
     Under capital adequacy  guidelines and the regulatory  framework for prompt
     corrective  action, the Corporation and the Bank must meet specific capital
     guidelines that involve quantitative  measures of the assets,  liabilities,
     and  certain   off-balance-sheet   items  as  calculated  under  regulatory
     accounting  practices.  The  capital  amounts and  classification  are also
     subject to qualitative  judgments by the regulators about components,  risk
     weighting, and other factors.

     Quantitative  measures established by regulation to ensure capital adequacy
     require  the  maintenance  of minimum  amounts and ratios (set forth in the
     tables  below) of total and Tier I capital (as defined in the  regulations)
     to riskweighted assets (as defined).  Management  believes,  as of December
     31,  1996,  that the  Corporation  and the Bank meet all  capital  adequacy
     requirements to which they are subject.

     As of December 31, 1996, the most recent  notification  from the regulatory
     agencies categorized the corporation and the bank as well capitalized under
     the regulatory framework for prompt corrective action. To be categorized as
     well capitalized,  the Corporation and 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 those notifications that
     management believes have changed those categories.

     merge  with  and  into  CNB (the " Bank  Merger")  in  accordance  with the
     Agreement and Plan of Merger  attached  hereto as Exhibit "A" ("Bank Merger
     Agreement") and pursuant to the provisions of The National Bank Merger Act,
     12  U.S.C.ss.215a  (the  "Bank  Merger  Act").  CNB shall be the  surviving
     corporation in the Bank Merger  (sometimes  hereinafter  referred to as the
     "Surviving  Bank") and shall continue to be a national banking  association
     and  the  separate  corporate   existence  of  CNB  with  all  its  rights,
     privileges,  immunities, powers and franchises shall continue unaffected by
     the Bank  Merger.  The name of the  Surviving  Bank shall be "The  Citizens
     National  Bank",  "Citizens Bank,  N.A." or "The Citizens  National Bank of
     Pennsylvania", subject to any necessary prior regulatory approval.

(c)  The  closing of the Merger (the  "Closing")  shall take place at such place
     and time and on such date,  following  three (3)  business  days' notice to
     NLBI, as shall be agreed upon by all parties, which date shall not be later
     than  the  30th  business  day  after  (i) the last  approval  of  required
     governmental authorities is granted and any related waiting periods expire,
     (ii) the lifting, discharge or dismissal of any stay of any such

                                        2

<PAGE>

     governmental approval or of any injunction against the Merger and (iii) all
     shareholder approvals required by the parties hereunder are received.

(d)  Immediately following the Closing, and provided that this Agreement has not
     been terminated or abandoned  pursuant to Article VII hereof, HNC North and
     NLBI will  cause  articles  of merger  (the  "Articles  of  Merger")  to be
     delivered  and  properly   filed  with  the  Department  of  State  of  the
     Commonwealth of Pennsylvania (the "Department of State").  The Merger shall
     become  effective on 11:59 p.m. on the day on which the Closing  occurs and
     Articles  of Merger  are filed with the  Department  of State or such later
     date and time as may be specified in the Articles of Merger (the "Effective
     Time").  The  "Effective  Date" when used herein means the day on which the
     Effective  Time for the Merger occurs.  The Bank Merger of Slatington  with
     and into CNB shall become  effective and the Bank Merger Agreement shall be
     consummated  on the Effective  Date or the date upon which the OCC issues a
     Certificate  of Merger,  whichever  is later (the  "Bank  Merger  Effective
     Date"). On the Bank Merger Effective Date,  Slatington shall cease to exist
     as a separate  banking  institution,  and CNB shall  become  the  surviving
     institution of the Bank Merger.

(e)  At the  Effective  Time,  the articles of  incorporation  and bylaws of HNC
     North in  effect  immediately  prior  to the  Effective  Time  shall be the
     articles of incorporation and bylaws of the Surviving  Corporation.  At the
     Effective Time, the directors and officers of HNC North  immediately  prior
     to the Effective Time shall be and become the directors and officers of the
     Surviving  Corporation with such additions or deletions as HNC, in its sole
     discretion, may determine.

                                   ARTICLE II
                            CONVERSION OF SHARES AND
                         EXCHANGE OF STOCK CERTIFICATES

SECTION 2.1 Conversion of Shares.

     On the Effective Date (as defined in Section 1.1(d) of this  Agreement) the
shares of NLBI 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 NLBI Common
     Stock,  par value  $10.00  per  share  ("NLBI  Common  Stock")  issued  and
     outstanding  immediately  before the Effective Date shall, on the Effective
     Date, be converted  into and become,  without any action on the part of the
     holder thereof,  the right to receive 3.57 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  498,008
     shares and the Exchange Ratio shall be 3.57.


                                        3

<PAGE>

(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)  Assumption of Stock Options.
     ----------------------------

     HNC  shall  assume  the  obligations  of  NLBI  under  the  stock  options,
     outstanding as of the date of this  Agreement,  to purchase 5,000 shares of
     NLBI Common Stock which remain unexercised on the Effective Date (the "NLBI
     Options").  The holder of the NLBI Options  shall  receive stock options to
     purchase,  on the same terms and  conditions as were  applicable  under the
     assumed NLBI  Options,  a number of shares of HNC Common Stock equal to the
     product of the Exchange Ratio and the number of shares of NLBI Common Stock
     subject to such NLBI  Option.  The option  exercise  price per share of HNC
     Common Stock shall be equal to the option  exercise price per share of NLBI
     Common Stock divided by the Exchange Ratio (the option price per share,  as
     so determined, being rounded upward to the nearest full cent). Such options
     to be received by the NLBI Option  holder shall be subject to  proportional
     adjustment under Section 2.1(b) of this Agreement.  Provided, however, that
     the  obligation  to assume  the NLBI  Options  by HNC is  conditioned  upon
     receipt of copies of all executed outstanding options as disclosed on Annex
     2.1(c).

(d)  No  Fractional  Shares.
     -----------------------

     No  fractional  shares of HNC Common  Stock,  and no scrip or  certificates
     therefor,  shall be issued in  connection  with the Merger.  In lieu of the
     issuance of any fractional  share to which he would  otherwise be entitled,
     each former  shareholder  of NLBI 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(e) of this Article II).

(e)  Closing Market Price.
     ---------------------

     For  purposes  of this  Agreement,  the Closing  Market  Price 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 2, 1998 were to be the Effective Date, then the Price
     Determination  Period would be September 28, 29, 30, October 1, 2, 5, 6, 7,
     8, 9, 12, 13,  14,  15,  16,  19, 20, 21, 22, 23,  1998.) 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

                                        4

<PAGE>

     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 1998 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 NLBI.

(f) NLBI Treasury Stock.
     --------------------

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

(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.

     (h)  HNC North  Common  Stock.  Each share of HNC North 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 North Common Stock.

SECTION 2.2 Exchange of Stock Certificates.

     NLBI 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 NLBI 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 NLBI 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 NLBI a notice
     specifying the procedures to be followed in surrendering such shareholder's
     NLBI Common Stock certificates.

(b) Surrender of Certificates.
     ---------------------------

     As promptly as possible after receipt of the Exchange Agent's notice,  each
     former shareholder of NLBI shall surrender his NLBI Common

                                        5

<PAGE>

     Stock  certificates  to the Exchange  Agent;  provided,  that if any former
     shareholder  of NLBI shall be unable to  surrender  his NLBI  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 NLBI Common Stock  certificates
     from a former  NLBI  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 NLBI 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(d) 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 NLBI who has not prior to the payment date  surrendered  his
     NLBI 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  NLBI  upon  proper  surrender  of his  NLBI  Common  Stock
     certificates.

(d)  Failure to Surrender Certificates.
     ----------------------------------

     All NLBI 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 NLBI shall not have properly  surrendered  his NLBI
     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 for his benefit.  From and after
     any such sale,  the sole right of such former  shareholder of NLBI 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 NLBI,
     without   interest,   upon  proper  surrender  of  his  NLBI  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 NLBI  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 NLBI 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

                                        6

<PAGE>

     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 NLBI  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 NLBI
     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 NLBI Common  Stock,  transmittal  materials for use in exchanging
     certificates  representing NLBI Common Stock for certificates  representing
     HNC  Common  Stock  into  which  the  former  have  been  converted  in the
     Reorganization and Merger.

(g)  Closing of Stock Transfer Books;  Cancellation of NLBI  Certificates.
     ---------------------------------------------------------------------

     Upon the Effective  Date,  the stock  transfer  books for NLBI Common Stock
     will be closed and no further transfers of shares of NLBI Common Stock will
     thereafter  be made or  recognized.  All  certificates  for  shares of NLBI
     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 NLBI 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
     the  Effective  Date.  Until  surrendered,   each  certificate  theretofore
     evidencing  shares of NLBI 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 NLBI 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 NLBI  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 NLBI Common Stock are  surrendered  by a NLBI  shareholder to
     HNC for exchange, HNC shall have the right

                                        7

<PAGE>

     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(d)  to each  person
     entitled thereto.

(j)  Unclaimed  Shares.
     ------------------

     In the event that any certificates for shares of NLBI Common Stock have not
     been  surrendered for exchange in accordance with this Section on or before
     the  second  anniversary  of the  Effective  Time,  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 NLBI Common Stock whose  Unclaimed  Shares have been sold,  to be
     paid to them upon surrender of the  certificates  for shares of NLBI Common
     Stock.  From and after any such sale,  the sole right of the holders of the
     unsurrendered  certificates for shares of NLBI 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 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 may, in its
     discretion at any time prior to the Effective  Time,  designate a direct or
     indirect  wholly-owned  subsidiary  to  substitute  for  HNC  North  as the
     constituent  corporation in the Merger by written notice to NLBI so long as
     the exercise of this right does not cause a material delay in  consummation
     of the transactions  contemplated  herein. HNC shall also have the right to
     cause NLBI or such substitute to be the Surviving Corporation of the 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 NLBI 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:

          liabilities  of any  other  financial  services  institution  or other
          corporation  or entity,  whether by issuance or exchange of HNC Common

     (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 or HNC North from  taking,  or to limit in any way the

                         REPRESENTATIONS AND WARRANTIES

SECTION 3.1 Representations and Warranties of NLBI and Slatington.

     NLBI and  Slatington  represent  and  warrant to HNC and HNC North (and the
word "it" in this Article III refers to NLBI,  Slatington and each subsidiary of
either) 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.
     --------------------------------------------

     NLBI is a  corporation  duly  incorporated,  validly  existing  and in good
     standing under the laws of the  Commonwealth of Pennsylvania and is in good
     standing as a foreign corporation in each jurisdiction where the properties
     owned, leased or operated, or the business conducted, by NLBI requires such
     qualification,  except  for such  failure  to  qualify  or be in such  good
     standing which, when taken together with all other such failures, would not
     have a Material  Adverse  Effect on NLBI and its  subsidiaries,  taken as a
     whole.  NLBI is a registered  bank holding  company  under the Bank Holding
     Company Act of 1956, as amended.  NLBI owns,  directly or indirectly all of
     the  issued  and  outstanding   shares  of  capital  stock  of  Slatington.

     existing and in good standing under the

                                        9

<PAGE>

     laws of the United  States of America.  NLBI and  Slatington  each have the
     requisite  corporate and other power and authority  (including all federal,
     state,  local and foreign  governmental  authorizations)  to carry on their
     respective  businesses as now being conducted and to own its properties and
     assets.  NLBI has made  available to HNC a complete and correct copy of the
     articles  of  incorporation  and bylaws of NLBI,  and  Slatington  has made
     available  to HNC and HNC North a complete  and correct copy of the charter
     and bylaws of Slatington and such charter or articles,  as applicable,  and
     such bylaws are in full force and effect as of the date hereof.

               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 Merger is advisable and in the best interests
               of it and its shareholders, (b) approved this Agreement, the Bank

               consideration to be received by its shareholders pursuant to this
               Agreement,  at the time of its execution, is fair to such holders
               from a financial point of view.

          (z)  Fidelity Bonds.
               --------------

               Since at least  December 31, 1990,  Slatington  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, 1990,  the aggregate  amount of all
               potential  claims under such bonds has not  exceeded  $50,000 and
               neither  NLBI nor  Slatington  is aware of any facts  which would
               reasonably  form the basis of a claim under such  bonds.  Neither
               NLBI nor Slatington has reason to

     referred to herein as the "Filing Date") by HNC with the SEC under the 1933

          no gain or loss will be  recognized  by the  shareholders  of NLBI who
          receive  solely HNC Common  Stock upon the exchange of their shares of
          NLBI Common Stock for shares of HNC Common Stock;

     (iv) The tax  basis  of the HNC  Common  Stock to be  received  by the NLBI

                  THE CITIZENS NATIONAL BANK OF SLATINGTON, PA

                                  with and into

                              under the charter of

                     THE CITIZENS NATIONAL BANK OF LANSFORD

     THIS AGREEMENT AND PLAN OF MERGER ("Bank Merger  Agreement") is dated as of
July 28, 1998, by and between THE CITIZENS NATIONAL BANK OF LANSFORD, a national

Box 128, Lansford, Pennsylvania 18232 ("CNB"), and THE CITIZENS NATIONAL BANK OF
SLATINGTON, PA., a national banking association,  having its principal office at
502 Main Street, Slatington,  Pennsylvania 18080 ("Slatington") (the two parties
being sometimes collectively referred to as the "Constituent Banks") each acting
pursuant to  resolutions  approved  and adopted by the vote of a majority of its
directors.

                                   WITNESSETH:

with the terms and conditions set forth therein and herein; and

     WHEREAS,  the respective Boards of Directors of Slatington and CNB deem the

<PAGE>

     WHEREAS,  the  respective  Boards of Directors of  Slatington  and CNB have
adopted resolutions  approving and adopting this Bank Merger Agreement,  and the
respective  Boards of  Directors of  Slatington,  CNB and HNC North,  Inc.,  the
parent  bank  holding  company of CNB ("HNC  North")  have  adopted  resolutions

Agreement requires the affirmative vote of the holders of at least two-thirds of
the  outstanding  shares of Slatington  Common Stock and the holders of at least
two-thirds of the outstanding shares of CNB Common Stock;

     NOW,  THEREFORE,  in consideration of their mutual covenants and agreements
contained  herein and in the  Reorganization  Agreement,  and for the purpose of
stating the method,  terms and  conditions  of the Bank  Merger,  including  the
rights of the shareholders of Slatington,  and such other details and provisions
as are deemed  desirable,  the parties  hereto,  intending  to be legally  bound
hereby, agree as follows:

     1. The Bank Merger. Subject to the terms and conditions of this Bank Merger
Agreement  and  the  Reorganization   Agreement,  and  in  accordance  with  the
provisions of the Act of November 7, 1918,  as amended (12 U.S.C.  ss.215a) (the
"Bank Merger Act") (as defined in Section 1.1 of the Reorganization  Agreement),
Slatington  shall be merged with and into CNB under the Bank Merger Act, and CNB
shall  be  the  surviving  association.  On the  Effective  Date,  the  separate
existence of Slatington shall cease, and CNB shall be the surviving  association
(the  "Surviving  Association"),  the principal and branch offices of Slatington
shall become  authorized  branch  offices of CNB ; and all the  property  (real,
personal and mixed),  rights,  powers, duties, and obligations of Slatington and
CNB shall be taken and deemed to be  transferred  to and vested in the Surviving
Association,  CNB,  without  further act or deed, as provided by applicable laws
and regulations.

     2. Name and Location of Principal  Office.  Subject to any necessary  prior
regulatory approval, the name of the Surviving Association shall be The Citizens
National  Bank,   Citizens  Bank,  N.  A.  or  The  Citizens  National  Bank  of
Pennsylvania,  and the location of its principal  office shall be 13-15 W. Ridge
Street, Lansford, Pennsylvania 18232.

     3. Articles of Association. The Articles of Association of CNB as in effect
immediately  prior to the Effective  Date, at the Effective Date and thereafter,

in accordance with applicable law.

     4.  Bylaws.  The  Bylaws  of  CNB as in  effect  immediately  prior  to the
Effective Date, at the Effective Date and thereafter, shall be the Bylaws of the

<PAGE>


     5.  Conversion  of Shares.  The manner  and basis of  converting  shares of
common stock of the Constituent Banks shall be as follows:

     5.1.  Conversion of  Slatington  Common  Stock.  On the Effective  Date (as
     defined in Section 1.1(d) of the Reorganization  Agreement),  the shares of
     Slatington Common Stock then outstanding and eligible for conversion shall,
     by virtue of the  merger and  without  any action on the part of the holder
     thereof,  be converted  into shares of CNB Common Stock in accordance  with
     the terms of and as provided in this Bank Merger Agreement.  From and after
     the Effective Date, each  certificate  which,  prior to the Effective Time,
     represented  shares of Slatington Common Stock shall evidence  ownership of
     shares of CNB Common Stock on the basis set forth herein.

     5.2.  Stock of CNB. The shares of CNB Common  Stock issued and  outstanding
     immediately  prior to the  Effective  Date shall  continue to be issued and
     outstanding shares of Common Stock of the Surviving  Association.  From and
     after the Effective Date,  each  certificate  that,  prior to the Effective
     Date,  represented  shares of CNB Common Stock, shall evidence ownership of
     shares of such Common Stock of the Surviving Association.

     6.  Surrender  and Exchange of  Slatington  Certificates.  On the Effective
Date,  Slatington  Common Stock  certificates  shall be exchanged for CNB Common
Stock certificates.

     7. Effect of Bank Merger. On the Effective Date, the Surviving  Association
shall  succeed,  without  further act or deed, to all of the  property,  rights,
powers,  duties and obligations of the Constituent  Banks in accordance with the
Bank Merger Act. Any claim  existing or action  pending by or against  either of
the  Constituent  Banks may be  prosecuted to judgment as if the Bank Merger had
not taken place, and the Surviving Association may be substituted in its place.

     8.  Continuation of Business.  The Surviving  Association shall continue in
business with the assets and liabilities of each of the Constituent  Banks.  The
Surviving  Association  shall be a national  banking  association  organized and
having  perpetual  existence  under the laws of the  United  States.  Any branch
offices of the Surviving  Association  shall  consist of CNB's and  Slatington's
present principal and branch offices and any other branch office or offices that
CNB and Slatington may be authorized to have as of the Effective Date. As of the
Effective Date, the separate existence of Slatington shall cease.

<PAGE>

     9. Board of  Directors  and  Officers.  The  directors  of CNB as in effect
immediately  prior to the Effective Date shall be the directors of the Surviving
Association, and four (4) persons appointed by Slatington and who are acceptable
to CNB shall be  appointed to serve as directors of CNB until such time as their
successors have been duly elected,  qualified, or appointed. The officers of CNB
as in effect  immediately  prior to the Effective  Date shall be the officers of
the Surviving Association,  with such changes as shall be made from time to time
by the Board of Directors of CNB.

     10.  Effective  Date of the Bank  Merger.  The  Effective  Date of the Bank
Merger  shall  be  as  defined  and  provided  for  in  Section  1.1(d)  of  the
Reorganization Agreement.

     11.  Further  Assurances.  If at any time the Surviving  Association  shall
consider or be advised that any further  assignments,  conveyances or assurances
are  necessary  or  desirable  to vest,  perfect  or  confirm  in the  Surviving
Association  title to any property or rights of Slatington,  or otherwise  carry
out the provisions hereof,  the proper officers and directors of Slatington,  as
of the Effective Date, on behalf of Slatington shall execute and deliver any and
all proper assignments,  conveyances and assurances, and do all things necessary
or desirable to vest, perfect or confirm title to such property or rights in the
Surviving Association and otherwise carry out the provisions hereof.

     12. Shareholder Approval.  This Bank Merger Agreement shall be approved and
adopted by the affirmative vote of shareholders of each of the Constituent Banks
owning at least two-thirds of its common stock outstanding.

     13. Termination and Amendment. This Bank Merger Agreement may be terminated
as  provided in Section 7.1 of the  Reorganization  Agreement.  This Bank Merger
Agreement  shall be  terminated  and the Bank Merger  shall be  abandoned in the
event  that  prior  to  the  Effective  Date  the  Reorganization  Agreement  is
terminated as provided therein. Since time is of the essence to this Bank Merger
Agreement,  if for any reason the transaction shall not have been consummated by
June 30, 1999, this Bank Merger  Agreement shall terminate  automatically  as of
that date unless  extended,  in writing,  prior to said date by mutual action of
the Boards of Directors of the parties.  If there is termination  after approval
of the Bank Merger by the Office of the Comptroller of the Currency (the "OCC"),
the parties shall  execute and file with the OCC prior to the  Effective  Date a
statement of termination of the Bank Merger.  Notwithstanding  prior approval by
the shareholders of Slatington, this Bank Merger Agreement may be amended in any
respect in the manner and subject only to the  limitations  set forth in Section
8.7 of the Reorganization Agreement.

     14. Notwithstanding any term of this Bank Merger Agreement to the contrary,
CNB may, in its discretion at any time prior to the Effective Time,  designate a
direct  or  indirect  wholly-owned  subsidiary  to  substitute  for  CNB  as the
constituent  association  in the Bank Merger by written  notice to Slatington so
long  as the  exercise  of  this  right  does  not  cause a  material  delay  in
consummation of the transactions  contemplated  herein.  CNB shall also have the
right to cause  Slatington  to be the Surviving  Corporation  of the Bank Merger
described so long as the exercise of such right does not


<PAGE>

have a material adverse effect on the interests of the Slatington shareholder or
cause a material delay in, or otherwise  adversely  affect,  consummation of the
transactions  contemplated herein; if such right is exercised,  this Bank Merger
Agreement shall be deemed to be modified to accord such change.

     15.  Obligations.  The obligations of CNB and Slatington to effect the Bank
Merger  shall  be  subject  to  all  terms  and  conditions   contained  in  the
Reorganization Agreement, except as may be provided by applicable law.

     16.  Extensions;  Waivers.  Each party, by a written instrument signed by a
duly authorized  officer,  may extend the time for the performance of any of the
obligations or other acts of the party hereto, and may waive compliance with any
obligations of the other party contained in this Bank Merger Agreement.

     17. Notices. Any notice or other communication  required or permitted under
this Bank Merger Agreement shall be given, and shall be effective, in accordance
with the provisions of the Reorganization Agreement.

     18. Counterparts;  Headings.  This Bank Merger Agreement may be executed in
several counterparts,  and by the parties hereto on separate counterparts,  each
of which will constitute an original. The headings and captions contained herein
are for reference purposes only and do not constitute a part hereof.

     19.  Governing  Law.  This Bank Merger  Agreement  shall be governed by and
construed  in  accordance  with the laws of the  Commonwealth  of  Pennsylvania,
except to the extent governed or controlled by federal law.

                              INVESTMENT AGREEMENT

<PAGE>


                              INVESTMENT AGREEMENT

     THIS AGREEMENT  dated as of July 28, 1998,  between  HARLEYSVILLE  NATIONAL
ORPORATION ("HNC") and NORTHERN LEHIGH BANCORP, INC. ("NLBI"),

                                   WITNESSETH:

     WHEREAS,  HNC and NLBI have,  simultaneously with executing this Agreement,
entered into an Agreement and Plan of Reorganization dated as of the date hereof
(the "Plan"); and

     WHEREAS,  as a condition to HNC's entry into the Plan and in  consideration
of such entry,  NLBI has agreed to issue to HNC, on the terms and conditions set
forth  herein,  options  entitling  HNC to purchase up to an aggregate of 27,760
shares (the "Shares") of NLBI's common stock,  par value $10.00 per share ("NLBI
Common Stock");

     NOW,  THEREFORE,  in  consideration  of the  execution  of the Plan and the
agreements herein contained, HNC and NLBI, intending to be legally bound hereby,
agree as follows:

     1.  Concurrently  with the execution of the Plan and this  Agreement,  NLBI
shall issue to HNC a option or options in the form of  Attachment  A hereto (the
"Option",  which term as used  herein  shall  include  any  options  issued upon
transfer or exchange of the  original  Option or pursuant to Paragraph 4 of this
Agreement)  to purchase up to 27,760  shares of NLBI Common  Stock.  Each Option
shall be  exercisable  at a price per share of $57.00,  subject to adjustment as
therein  provided (the "Exercise  Price").  So long as the Option is outstanding
and  unexercised,  NLBI  shall at all  times  maintain  and  reserve,  free from
preemptive rights,  such number of authorized but unissued or treasury shares of
NLBI  Common  Stock as may be  necessary  so that the  Option  may be  exercised
without additional authorization of NLBI Common Stock after giving effect to all
other  options,  warrants,  convertible  securities  and other rights to acquire
shares  of NLBI  Common  Stock  at the time  outstanding.  NLBI  represents  and
warrants that it has duly authorized the issuance of the Shares upon exercise of
the Option and  covenants  that the Shares  issued  upon  exercise of the Option
shall be duly authorized,  validly issued and fully paid and  nonassessable  and
subject to no  preemptive  rights.  The  Option  and the Shares are  hereinafter
collectively referred to, from time to time, as the "Securities".

     So long as the Option is owned by HNC, in no event shall HNC  exercise  the
Option  for a number of shares of NLBI  Common  Stock  which,  when added to the
number of shares of NLBI Common Stock owned or controlled by HNC (otherwise than
in a fiduciary  capacity)  would result in HNC owning or controlling  (otherwise
than in a  fiduciary  capacity)  more than 19.9  percent  of the  shares of NLBI
Common  Stock issued and  outstanding  immediately  after giving  effect to such
exercise.

     2. Subject to the terms and conditions hereof, HNC may exercise or sell the
Option,  in whole or in part,  upon:  (i) a  willful  breach of the Plan by NLBI
which would permit termination of


<PAGE>

the Plan by HNC; (ii) the failure of NLBI's  shareholders to approve the Plan at
a meeting  called for such purpose after the  announcement  by any person (other
than HNC) of an offer or  proposal  to acquire 15 percent or more of NLBI Common
Stock, or to acquire,  merge or consolidate  with NLBI or to purchase or acquire
all or substantially  all of NLBI's assets;  (iii) the acquisition by any person
(other than HNC) of  beneficial  ownership  of 15 percent or more of NLBI Common
Stock  exclusive of shares of NLBI Common Stock sold  directly or  indirectly to
such  person by HNC;  (iv) any person  (other  than HNC) shall have  commenced a
tender or exchange offer, or shall have filed an application with an appropriate
bank  regulatory  authority  with  respect to a  publicly  announced  offer,  to
purchase or acquire  securities  of NLBI such that,  upon  consummation  of such
offer, such person would own, control or have the right to acquire 15 percent or
more of NLBI Common Stock (before  giving effect to any exercise of the Option);
or (v) NLBI shall have entered into an agreement or other  understanding  with a
person (other than HNC) for such person to acquire,  merge or  consolidate  with
NLBI or to purchase or acquire all or substantially all of NLBI's assets.  HNC's
right to exercise the Option shall terminate and be of no further effect, except
as to notices of exercise given prior thereto, upon termination of the Option as
provided in Paragraph  10 thereof.  As used in this  Paragraph  2,  "person" and
"beneficial   ownership"  shall  have  the  same  meanings  as  in  the  Option.
Notwithstanding the foregoing,  NLBI shall not be obligated to issue Shares upon
exercise  of the  Option  (i) in the  absence of any  required  governmental  or
regulatory approval or consent necessary for NLBI to issue the Shares or for HNC
to exercise the Option or prior to the  expiration or termination of any waiting
period required by law or (ii) so long as any injunction or other order,  decree
or ruling issued by any federal or state court of competent  jurisdiction  is in
effect  which  prohibits  the sale or delivery  of the  Shares.  Any sale of the
Option, in whole or in part, or any of the Shares by HNC, other than a sale to a
majority-owned subsidiary of HNC, shall be subject to the right of first refusal
of NLBI (or any  assignee  or  assignees  of NLBI the  identity of whom or which
prior to the date thereof has been given to HNC) at a price equal to the written
offer price which HNC receives  from a third party (other than a  majority-owned
subsidiary  of HNC) and  intends to  accept.  The right of first  refusal  shall
terminate 15 days after notice of HNC's  intention to sell has been delivered to
NLBI. If an offer is made for a consideration which in whole or in part consists
of other than cash, the value of the non-cash portion of the consideration shall
be determined by a recognized  investment  banking firm selected  jointly by HNC
and NLBI, and such determination  shall in no event be made later than the fifth
day after notice of HNC's  intention to sell has been  delivered to NLBI. In the
event of the failure or refusal of NLBI to purchase the Option or all the Shares
covered by HNC's notice to sell,  HNC may,  within 30 days from the date of such
notice,  unless  additional time is needed to give  notification to or to obtain
approval  from any  governmental  or regulatory  authority  and, if so required,
within five days after the date on which the  required  notification  period has
expired or been  terminated or such approval has been obtained and any requisite
waiting period with respect thereto has passed, sell all, but not less than all,
of the  portion of the  Option or such  Shares  covered  by such  notice to such
proposed  transferee  at no less than the price  specified  and on terms no more
favorable to the buyer than those set forth in the notice.

     3. Subject to applicable regulatory  restrictions,  from and after the date
on which any event described in the second paragraph of this Paragraph 3 occurs,
the Holder as defined in the Option  (which shall  include a former  Holder) who
has  exercised  the  Option in whole or in part  shall have the right to require
NLBI to redeem some or all of the Shares at a redemption price per share


<PAGE>

(the "Redemption Price") equal to the highest of (i) 150 percent of the Exercise
Price,  (ii) the  highest  price paid or agreed to be paid for any share of NLBI
Common Stock by an Acquiring Person (as defined in the Option) during the twelve
months  immediately  preceding  the  date  notice  of the  election  to  require
redemption is given by the Holder under the third  paragraph of this Paragraph 3
(as  appropriately  adjusted to reflect any of the events described in Paragraph
7(A) of the Option) and (iii) in the event of a sale of all or substantially all
of NLBI's assets, (x) the sum of the price paid in such sale for such assets and
the current  market value of the  remaining  assets of NLBI as  determined  by a
recognized  investment banking firm selected by such Holder,  divided by (y) the
number  of shares of NLBI  Common  Stock  then  outstanding.  If the price  paid
consists in whole or in part of the  securities  or assets other than cash,  the
value of such  securities or assets shall be their then current  market value as
determined by a recognized  investment  banking firm selected by the Holder. The
Holder's  right to require  NLBI to redeem some or all of the Shares  under this
Paragraph 3 shall expire on the close of business on the 180th day following the
occurrence of any event described in the second paragraph of this Paragraph 3.

     The redemption rights provided in this Paragraph 3 shall become exercisable
upon the occurrence of any of the following  events:  (i) the acquisition by any
person (other than HNC or any  subsidiary of HNC) of beneficial  ownership of 25
percent or more of the NLBI Common Stock  (before  giving effect to any exercise
of the  Option)  exclusive  of shares of NLBI  Common  Stock  sold  directly  or
indirectly to such person by HNC or (ii) a transaction  of the type specified in
Paragraph 2(v) shall have been consummated. As used in this Paragraph 3 "person"
and "beneficial ownership" shall have the same meanings as in the Option.

     The Holder may  exercise its right to require NLBI to redeem some or all of
the Shares  pursuant to this  Paragraph 3 by  surrendering  for such  purpose to
NLBI, at its principal  office within the time period specified in the preceding
paragraph, a certificate or certificates representing the number of Shares to be
redeemed  accompanied by a written notice stating that it elects to require NLBI
to redeem  all or a  specified  number of such  Shares  in  accordance  with the
provisions  of this  Paragraph 3. As promptly as  practicable,  and in any event
within  ten  business  days after the  surrender  of such  certificates  and the
receipt of such  notice  relating  thereto,  NLBI  shall  deliver or cause to be
delivered to the Holder the applicable  Redemption Price for the Shares which it
is not then prohibited under  applicable law or regulation from redeeming,  and,
if the  Holder has given NLBI  notice  that less than the full  number of Shares
evidenced by the surrendered  certificate or certificates are to be redeemed,  a
new  certificate  or  certificates,  of like  tenor,  for the  number  of Shares
evidenced by such surrendered  certificate or  certificates,  less the number of
Shares  redeemed.  To the extent that NLBI is prohibited under applicable law or
regulation,  or by judicial or administrative  action, from redeeming all of the
Shares as to which the Holder has given notice to redeem  hereunder,  NLBI shall
immediately notify the Holder and thereafter deliver or cause to be delivered to
the Holder the applicable  Redemption  Price for such number of the Shares as it
is not  prohibited  from  redeeming  within ten business  days after the date on
which NLBI is no longer so prohibited;  provided, however, that at the option of
HNC, at any time after  receipt of such notice from NLBI,  NLBI shall deliver to
the Holder a certificate  for such number of the Shares as it is then prohibited
from redeeming,  or, at the Holder's option, all the Shares, and NLBI shall have
no further obligation to redeem such Shares.


<PAGE>

     4. In the event that NLBI issues any additional Shares of NLBI Common Stock
pursuant to  outstanding  stock options after the date of this  Agreement,  NLBI
shall issue  additional  options to HNC,  such that,  after such  issuance,  the
number of Shares of NLBI Common Stock subject to all options hereunder, together
with any shares of NLBI Common Stock previously  issued pursuant hereto,  equals
19.9  percent of the shares of NLBI Common  Stock then  issued and  outstanding.
Such additional options shall be identical to the Option.

     5. NLBI will not enter into any transaction described in (a), (b) or (c) of
Paragraph  6(A) of the Option  unless the  Acquiror  (as  defined in the Option)
assumes in writing,  in form and substance  satisfactory to the Holder,  all the
obligations of NLBI hereunder.

     6. This  Agreement  shall not be  assignable by HNC except to any direct or
indirect subsidiary, affiliate or successor of HNC.

     7. Without  limiting the foregoing or any remedies  available to HNC, it is
specifically  acknowledged that HNC would not have an adequate remedy at law for
any breach of this Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or threatened violations
of the obligations of any person subject to this Agreement.

                                     OPTION

                       to Purchase up to 27,760 Shares of
                                  Common Stock
                                       of
                          Northern Lehigh Bancorp, Inc.


     This  is  to  certify  that,  for  value  received,  HARLEYSVILLE  NATIONAL
CORPORATION  ("HNC")  or  any  permitted  transferee  (HNC  or  such  transferee
hereinafter the "Holder") is entitled to purchase,  subject to the provisions of
this Option and of the Agreement (as hereinafter defined),  from NORTHERN LEHIGH
BANCORP, INC. ("NLBI"), at any time on or after the date hereof, an aggregate of
up to 27,760  fully paid and  nonassessable  shares of common  stock,  par value
$10.00 per share  ("NLBI  Common  Stock") of NLBI at a price per share  equal to
$57.00 subject to adjustment as herein provided (the "Exercise Price").

     1. Exercise of Option.

     Subject to the provisions hereof and the limitations set forth in Paragraph
2 of an Investment  Agreement  dated as of July 28, 1998, by and between HNC and
NLBI (the  "Agreement")  executed and delivered in connection  with an Agreement
and Plan of Reorganization  dated as of July 28, 1998, between HNC and NLBI (the
"Plan"),  this  Option may be  exercised  at any time or from time to time on or
after the date  hereof.  This Option  shall be  exercised  by  presentation  and
surrender hereof to NLBI at its principal  office,  accompanied by (i) a written
notice of  exercise,  (ii)  payment to NLBI,  for the  account  of NLBI,  of the
Exercise  Price for the number of shares of NLBI Common Stock  specified in such
notice  and (iii) a  certificate  of the Holder  specifying  the event or events
which have  occurred  which  entitle  the Holder to  exercise  the  Option.  The
Exercise  Price for the number of shares of NLBI Common  Stock  specified in the
notice shall be payable in immediately  available funds.  This Option may not be
exercised in part for less than 4,000 shares, except (i) for an initial exercise
resulting in ownership of  approximately 5 percent of the outstanding  shares of
NLBI  Common  Stock  after  giving  effect to the  exercise,  (ii) as limited by
applicable law, regulation or regulatory order or (iii) when this Option becomes
exercisable  for less than 4,000 shares,  the  remaining  shares for which it is
then exercisable.

     Upon such presentation and surrender, NLBI shall issue promptly (and within
five  business  days if requested by the Holder) to the Holder or its  assignee,
transferee  or designee  the shares of NLBI Common  Stock to which the Holder is
entitled hereunder.

     If this Option should be exercised in part only, NLBI shall, upon surrender
of this Option for cancellation, execute and deliver a new Option evidencing the
rights of the  Holder  thereof  to  purchase  the  balance of the shares of NLBI
Common Stock purchasable hereunder. Upon receipt


<PAGE>

by NLBI of this Option, in proper form for exercise,  the Holder shall be deemed
to be the holder of record of the shares of NLBI Common Stock issuable upon such
exercise,  notwithstanding  that the  stock  transfer  books of NLBI may then be
closed or that certificates  representing such shares of NLBI Common Stock shall
not then be actually delivered to the Holder.  NLBI shall pay all expenses,  and
any and all United States federal, state and local taxes and other charges, that
may be payable in connection with the  preparation,  issue and delivery of stock
certificates  pursuant  to this  Paragraph  1 in the name of the  Holder  or its
assignee, transferee or designee.

     2. Reservation of Shares;  Preservation of Rights of Holder.

     NLBI shall at all times while this Option is  outstanding  and  unexercised
maintain and reserve, free from preemptive rights, such number of authorized but
unissued or treasury  shares of NLBI Common  Stock as may be  necessary  so that
this Option may be exercised  without  additional  authorization  of NLBI Common
Stock after giving effect to all other options, warrants, convertible securities
and other rights to acquire shares of NLBI Common Stock at the time outstanding.
NLBI further agrees

     (i)  that it will not,  by charter  amendment  or  through  reorganization,
          consolidation,  merger, dissolution or sale of assets, or by any other
          voluntary act, avoid or seek to avoid the observance or performance of
          any of the  covenants,  stipulations  or  conditions to be observed or
          performed hereunder or under the Agreement by NLBI,

     (ii) that it will use its best  efforts to take all action  (including  (A)
          complying  with all  premerger  notification,  reporting  and  waiting
          period requirements  specified in 15 U.S.C. ss.18a and the regulations
          promulgated  thereunder  and (B) in the  event  that  under  the  Bank
          Holding  Company Act of 1956 or the Change in Bank  Control Act or any
          other law,  prior  approval of the Board of  Governors  of the Federal
          Reserve System (the "Board"),  the Securities  Regulatory  Commissions
          (SEC), or any other regulatory  agency is necessary before this Option
          may be exercised,  cooperating  fully with the Holder in preparing any
          and all such  applications and providing such information to the Board
          as such agency may  require) in order to permit the Holder to exercise
          this  Option  and NLBI duly and  effectively  to issue  shares of NLBI
          Common Stock hereunder, and

     (iii)that it will promptly take all action  necessary to protect the rights
          of the Holder against dilution as provided herein.

     3. Fractional Shares.

     NLBI shall not be required to issue fractional  shares of NLBI Common Stock
upon  exercise of this Option but shall pay for such fraction of a share in cash
or by certified or official bank check at the Exercise Price.

     4. Exchange,  Transfer or Loss of Option.

     This Option is  exchangeable  or,  subject to Paragraph 2 of the Investment
Agreement,  transferable,  without  expense,  at the option of the Holder,  upon
presentation  and  surrender  hereof at the  principal  office of NLBI for other
Options of  different  denominations  entitling  the Holder to  purchase  in the
aggregate the same number of shares of NLBI Common Stock purchasable  hereunder.
The term "Option" as used herein  includes any Options for which this Option may
be exchanged.  Upon receipt by NLBI of evidence reasonably satisfactory to it of
the loss, theft,  destruction or mutilation of this Option,  and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Option,  if mutilated,  NLBI will execute and
deliver a new Option of like tenor and date.


<PAGE>

     This  Option may not be  exercised  or sold except in  accordance  with the
terms of the Agreement.

     5. Redemption.

          (A) Subject to applicable regulatory restrictions,  from and after the
     date on which any event described in the second paragraph of Paragraph 3 of
     the  Agreement  occurs,  the Holder shall have the right to require NLBI to
     redeem this Option at a redemption price (the "Redemption Amount") equal to
     the highest of (i) the number of shares of NLBI Common Stock for which this
     Option is then  exercisable  (the  "Conversion  Number")  multiplied by the
     Exercise  Price  multiplied  by 150%,  (ii) (x) the  highest  price paid or
     agreed  to be paid for any  share  of NLBI  Common  Stock by the  Acquiring
     Person  (as  hereinafter  defined)  during the  twelve  months  immediately
     preceding the date notice of the election to require redemption is given by
     the Holder under Paragraph 5(B)(such price to be appropriately  adjusted to
     reflect  the  effect  of any of the  events  described  in  Paragraph  7(A)
     hereof), less the Exercise Price,  multiplied by (y) the Conversion Number,
     and  (iii)  in the  event of the  sale of all or  substantially  all of the
     assets of NLBI, the Conversion  Number  multiplied by (x)(I) the sum of (a)
     the  price  paid for  such  assets,  (b) the  current  market  value of the
     remaining assets of NLBI, as determined by a recognized  investment banking
     firm selected by the Holder,  and (c) the Exercise Price  multiplied by the
     Conversion Number,  divided by (II) the sum of the number of shares of NLBI
     Common  Stock then  outstanding  and the  Conversion  Number,  less (y) the
     Exercise Price.  If, for the purpose of this calculation or calculating the
     Assigned Value (as hereinafter described), the price paid consists in whole
     or in part of  securities  or assets  other  than  cash,  the value of such
     securities or assets shall be their then current market value as determined
     by a  recognized  investment  banking  firm  selected  by the  Holder.  The
     Holder's right to require NLBI to redeem this Option under this Paragraph 5
     shall  expire at the close of  business  on the  180th  day  following  the
     occurrence of any event described in the second paragraph of Paragraph 3 of
     the Agreement.

          (B) The Holder of this Option may  exercise  its right to require NLBI
     to redeem this Option pursuant to this Paragraph 5 by surrendering for such
     purpose to NLBI,  at its  principal  office,  within  the period  specified
     above, this Option  accompanied by a written notice stating that the Holder
     elects  to  require  NLBI to redeem  this  Option  in  accordance  with the
     provisions  of this  Paragraph  5. As promptly as  practicable,  and in any
     event within ten business  days after the  surrender of this Option and the
     receipt of such notice relating thereto,  NLBI shall deliver or cause to be
     delivered  to the Holder the  Redemption  Amount  therefor  or the  portion
     thereof which it is not then prohibited under applicable law and regulation
     from delivering to the Holder.

          To  the  extent  that  NLBI  is  prohibited  under  applicable  law or
     regulation,  or as a result of  administrative  or  judicial  action,  from
     redeeming this Option in full, NLBI shall immediately notify the Holder and
     thereafter  deliver or cause to be  delivered  to the Holder the portion of
     the Redemption  Amount which it is no longer  prohibited from delivering to
     the  Holder  within  ten  business  days after the date on which NLBI is no
     longer so prohibited;


<PAGE>

     provided,  however,  that,  at the option of the Holder,  at any time after
     receipt  of such  notice,  NLBI  shall  deliver  to the Holder a new Option
     evidencing  the right to the Holder to  purchase  that  number of shares of
     NLBI Common Stock obtained by multiplying  the Conversion  Number in effect
     at such time by a fraction, the numerator of which is the Redemption Amount
     less the portion thereof (if any)  theretofore  delivered to the Holder and
     the denominator of which is the Redemption  Amount,  and NLBI shall have no
     further obligation to redeem such new Option.

          (C) As used in this  Option,  the  following  terms have the  meanings
     indicated:

               (a)  "Acquiring  Person"  shall  mean any  "Person"  (hereinafter
          defined) who or which shall be the "Beneficial  Owner" (as hereinafter
          defined) of 15% or more of NLBI Common Stock;

               (b) A "Person" shall mean any  individual,  firm,  corporation or
          other entity and include as well any syndicate or group deemed to be a
          "person" by Section  13(d)(3) of the Securities  Exchange Act of 1934,
          as amended;

               (c) A Person shall be a "Beneficial Owner" of all securities:

                    (i)  which  such  Person  or  any of  its  "Affiliates"  (as
               hereinafter  defined) or "Associates"  (as  hereinafter  defined)
               beneficially owns, directly or indirectly; and

                    (ii)  which  such  Person  or  any  of  its   Affiliates  or
               Associates  has (1) the right to acquire  (whether  such right is
               exercisable  immediately  or only  after the  passage  of time or
               otherwise)   pursuant   to   any   agreement,    arrangement   or
               understanding or upon the exercise of conversion rights, exchange
               rights,  warrants or options,  or otherwise,  or (2) the right to
               vote pursuant to any agreement, arrangement or understanding; and

               (d)  "Affiliate"  and  "Associate"   shall  have  the  respective
          meanings ascribed to such terms in Rule 12b-2 of the General Rules and
          Regulations  promulgated under the Securities Exchange Act of 1934, as
          amended, as in effect on the date of the Agreement.

               6. Certain Transactions.

          (A) In case NLBI

               (a) shall  consolidate with or merge into any Person,  other than
          the Holder or one of its  Affiliates,  and shall not be the continuing
          or surviving corporation of such consolidation or merger,

               (b) shall permit any Person,  other than the Holder or one of its
          Affiliates,  to merge  into NLBI and NLBI shall be the  continuing  or
          surviving  corporation,  but, in connection with such merger, the then
          outstanding  shares of NLBI  Common  Stock  shall be  changed  into or
          exchanged for stock or other securities of any other


<PAGE>

          Person or cash or any other property or shall  represent less than 25%
          of the shares of NLBI Common Stock  immediately after giving effect to
          the merger, or

               (c) shall sell or otherwise  transfer all or substantially all of
          its  assets  to  any  Person,  other  than  the  Holder  or one of its
          Affiliates,  then, and in each such case, the agreement governing such
          transaction  shall make proper provision so that this Option shall (at
          the option of the Holder,  in whole or in part), upon the consummation
          of any such  transaction  and upon the terms and  conditions set forth
          herein,  be converted into, or exchanged for, a option,  at the option
          of the  Holder,  of  either  (I) the  Acquiring  Bank (as  hereinafter
          defined), (II) any company which controls the Acquiring Bank, or (III)
          in the case of a merger  described in clause  (A)(b),  NLBI,  in which
          case such option shall be a newly issued option (in any such case, the
          "Substitute Option").

     (B) The following terms have the meanings indicated:

               (a)  "Acquiring  Corporation"  shall mean (I) the  continuing  or
          surviving corporation of a consolidation or merger with NLBI (if other
          than the NLBI), (II) the corporation  merging into NLBI in a merger in
          which the NLBI is the continuing or surviving person and in connection
          with  which  the then  outstanding  shares  of NLBI  Common  Stock are
          changed into or exchanged  for stock of other  securities of any other
          Person or cash or any other property or shall  represent less than 50%
          of the shares of NLBI Common Stock  immediately after giving effect to
          the merger,  and (III) the transferee of all or  substantially  all of
          NLBI's assets, NLBI or all or substantially all of the NLBI's assets;

               (b) "Substitute  Common Stock" shall mean the common stock issued
          by the issuer of the Substitute Option;

               (c) "Assigned Value" shall mean the Redemption Price per share of
          NLBI  Common  Stock  (as  defined  in  Paragraph  3 of the  Agreement)
          multiplied by the Conversion Number;

               (d) "Average  Price" shall mean the average  closing price (or if
          unavailable,  the average of the daily averages of the closing bid and
          asked prices) of a share of  Substitute  Common Stock for the one year
          immediately  preceding the consolidation,  merger or sale in question,
          but in no event  higher  than the  closing  price (or  average  of the
          closing bid and asked prices) of a share of Substitute Common Stock on
          the day preceding such consolidation, merger or sale; provided that if
          NLBI is the issuer of the Substitute  Option,  the Average Price shall
          be computed  with respect to a share of the common stock issued by the
          Person merging into NLBI or by any company which controls such Person,
          as the Holder may elect.  If the Average  Price  cannot be computed as
          aforesaid  because  neither  closing  prices nor closing bid and asked
          prices are available for such one-year period,  then the Average Price
          shall be the average fair market value of a share of Substitute Common
          Stock for such  period  (but in no event  higher  than the fair market
          value on


<PAGE>

          the day preceding such consolidation, merger or sale) as determined by
          a recognized investment banking firm selected by HNC.

          (C) The  Substitute  Option  shall have the same terms as this  Option
     provided  that if the  terms of the  Substitute  Option  cannot,  for legal
     reasons,  be the same as this  Option,  such  terms  shall be as similar as
     possible and in no event less advantageous to the Holder. The issuer of the
     Substitute  Option shall also enter into an agreement  with the then Holder
     of the Substitute  Option in substantially  the same form as the Agreement,
     which shall be applicable  to the  Substitute  Option.  For purposes of the
     Substitute Option and such agreement,  any event referred to in Paragraph 2
     or Paragraph 3 of the  Agreement  shall be deemed to have  occurred when it
     occurred with respect to NLBI.

          (D) The Substitute  Option shall be immediately  exercisable  for such
     number of shares of  Substitute  Common  Stock as is equal to the  Assigned
     Value divided by the Average  Price.  The exercise  price of the Substitute
     Option per share of Substitute  Common Stock shall be equal to the Exercise
     Price  multiplied  by a fraction in which the  numerator is the  Conversion
     Number and the  denominator  is the number of shares of  Substitute  Common
     Stock for which the Substitute Option is exercisable.

          (E) In no event,  pursuant to any of the foregoing  paragraphs,  shall
     the Substitute  Option be exercisable  for more than 19.9% of the aggregate
     of the  outstanding  shares of  Substitute  Common  Stock and the shares of
     Substitute Common Stock issuable upon exercise of the Substitute Option.

     7. Adjustment.

     The number of shares of NLBI Common Stock  purchasable upon the exercise of
this Option and the Exercise  Price shall be subject to adjustment  from time to
time as provided in this Paragraph 7:

          (A)(1) In case NLBI shall pay or make a dividend or other distribution
     on any class of capital stock of NLBI in NLBI Common  Stock,  the number of
     shares of NLBI Common Stock  purchasable upon exercise of this Option shall
     be  increased by  multiplying  such number of shares by a fraction of which
     the  denominator  shall  be the  number  of  shares  of NLBI  Common  Stock
     outstanding at the close of business on the day  immediately  preceding the
     date of such distribution and the numerator shall be the sum of such number
     of shares and the total  number of shares  constituting  such  dividend  or
     other distribution, such increase to become effective immediately after the
     opening of  business  on the day  following  such  distribution,  provided,
     however, that in no event shall the Option be exercised for more than 19.9%
     of the shares of NLBI Common Stock issued and outstanding.

          (2)  In  case  outstanding  shares  of  NLBI  Common  Stock  shall  be
     subdivided into a greater number of shares of NLBI Common Stock, the number
     of shares of NLBI Common Stock  purchasable upon exercise of this Option at
     the  opening  of  business  on the day  following  the day upon  which such
     subdivision


<PAGE>

     becomes effective shall be proportionately  increased,  and, conversely, in
     case outstanding  shares of NLBI Common Stock shall each be combined into a
     smaller number of shares of NLBI Common Stock, the number of shares of NLBI
     Common  Stock  purchasable  upon  exercise of this Option at the opening of
     business on the day following the day upon which such  combination  becomes
     effective shall be proportionately decreased, such increase or decrease, as
     the case may be, to become  effective  immediately  after  the  opening  of
     business  on the day  following  the day upon  which  such  subdivision  or
     combination becomes effective,  provided,  however,  that in no event shall
     the Option be  exercised  for more than 19.9% of the shares of NLBI  Common
     Stock issued and outstanding.

          (3)  The  reclassification  (excluding  any  transaction  in  which  a
     Substitute  Option  would be issued) of NLBI Common  Stock into  securities
     (other than NLBI Common Stock) and/or cash and/or other consideration shall
     be deemed to involve a subdivision or  combination,  as the case may be, of
     the number of shares of NLBI Common Stock outstanding  immediately prior to
     such  reclassification  into the number or amount of securities and/or cash
     and/or  other  consideration  outstanding  immediately  thereafter  and the
     effective date of such reclassification shall be deemed to be "the day upon
     which  such  subdivision  becomes  effective,"  or "the day upon which such
     combination  becomes  effective," as the case may be, within the meaning of
     clause (2) above.

          (4) NLBI may make  such  increases  in the  number  of  shares of NLBI
     Common Stock purchasable upon exercise of this Option, in addition to those
     required by this  subparagraph  (A), as shall be determined by its Board of
     Directors to be advisable in order to avoid  taxation so far as practicable
     of any dividend of stock or stock  rights or any event  treated as such for
     federal income tax purposes to the recipients.

     (B)  Whenever the number of shares of NLBI Common  Stock  purchasable  upon
exercise of this Option is adjusted as herein provided, the Exercise Price shall
be  adjusted  by a  fraction  in which the  numerator  is equal to the number of
shares  of  NLBI  Common  Stock  purchasable  prior  to the  adjustment  and the
denominator  is equal to the number of shares of NLBI Common  Stock  purchasable
after the adjustment.

     (C) For the purpose of this Paragraph 7, the term "NLBI Common Stock" shall
include  any shares of NLBI of any class or series  which has no  preference  or
priority in the payment of dividends or in the  distribution  of assets upon any
voluntary  or  involuntary  liquidation,  dissolution  or winding up of NLBI and
which is not subject to redemption by NLBI.

     8. Notice.

     (A) Whenever the number of shares for which this Option is  exercisable  is
adjusted as provided in Paragraph 7, NLBI shall promptly compute such adjustment
and mail to the Holder a certificate, signed by a principal financial officer of
NLBI,  setting  forth the number of shares of NLBI  Common  Stock for which this
Option is exercisable as a result of such  adjustment,  a brief statement of the
facts  requiring  such  adjustment  and the  computation  thereof  and when such
adjustment will become effective.

<PAGE>

     (B) Upon the occurrence of any event which results in this Option  becoming
redeemable, as provided in Paragraph 5, NLBI shall promptly notify the Holder of
such event; and promptly compute the Redemption Amount and furnish to the Holder
a certificate,  signed by a principal  financial officer of NLBI,  setting forth
the Redemption Amount and the basis and computation thereof.

     (C) Upon the  occurrence of an event which results in this Option  becoming
convertible  into, or exchangeable  for, the Substitute  Option,  as provided in
Paragraph 6, the  Acquiring  Bank and NLBI shall  promptly  notify the Holder of
such event;  and, upon receipt from the Holder of its choice as to the issuer of
the Substitute  Option,  the Acquiring Bank and NLBI shall promptly  compute the
number of shares of Substitute  Common Stock for which the Substitute  Option is
exercisable  and  furnish to the  Holder a  certificate,  signed by a  principal
financial  officer of each of the  Acquiring  Bank and NLBI,  setting  forth the
number of shares of Substitute  Common Stock for which the Substitute  Option is
exercisable,  a  computation  thereof  and  when  such  adjustment  will  become
effective.

     9. Rights of Holder.

     (A) Without limiting the foregoing or any remedies available to the Holder,
it is  specifically  acknowledged  that the  Holder  would not have an  adequate
remedy  at law for any  breach  of the  provision  of this  Option  and  will be
entitled to specific performance of the


<PAGE>

obligations under, and injunctive relief against actual or threatened violations
of the obligations of any Person subject to, this Option.

     (B) Except as provided in the third  paragraph of  Paragraph 1 hereof,  the
Holder shall not, by virtue  hereof,  be entitled to any rights of a shareholder
in NLBI.

     10.  Termination.

     This  Option and the  rights  conferred  hereby  shall  terminate  (i) upon
willful breach of the Agreement by HNC, (ii) at the Effective Time of the Merger
pursuant  to the Plan,  (iii) upon  termination  of the Plan by HNC  pursuant to
Section 7.1(e) of the Plan; or (iv) to the extent this Option has not previously
been  exercised,  on the later of (A)  September 30, 1999 or (B) 18 months after
the occurrence of an event  described in Paragraph 2 of the Agreement,  provided
that such termination pursuant to this clause iv shall not affect any redemption
under  Paragraph 5 as to which  exercise  under  Paragraph  5(B) has  previously
occurred.

     11.  Governing  Law.

     This Option shall be governed by, and  interpreted in accordance  with, the
substantive laws of the Commonwealth of Pennsylvania.

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


Ladies and Gentlemen:

     We have acted as Special Counsel to Northern Lehigh Bancorp, Inc. ("NLBI"),
a  Pennsylvania  corporation,  and The  Citizens  National  Bank  of  Slatington
("Slatington"), a national banking association, in connection with the Agreement
and  Plan of  Reorganization,  dated  as of  July  __,  1998  (as  amended,  the
"Agreement"), by and among Harleysville National Corporation ("HNC"), HNC North,
Inc. ("HNC North"),  The Citizens  National Bank of Lansford  ("CNB"),  NLBI and
Slatington,  pursuant  to which NLBI will be merged with and into HNC North (the
"Merger").  While this firm  represents  NLBI and Slatington in connection  with
specific  legal  matters as to which we are consulted by them, we do not perform
or provide legal  services to either NLBI or  Slatington in connection  with the
day-to-day  operations of their  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 articles of association,  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.

<PAGE>

     Based upon and subject to the foregoing and the other terms and  provisions
hereof, it is our opinion that:

     1. NLBI is a business corporation that is duly organized,  validly existing

evidenced in the Subsisting  Corporation  Certificate issued by the Commonwealth
of  Pennsylvania,  Corporation  Bureau,  and is in good  standing  as a  foreign
corporation in each jurisdiction where the properties owned, leased or operated,
or the business conducted, by NLBI requires such qualification,  except for such
failure to qualify or be in such good standing  which,  when taken together with
all other such  failures,  would not have a Material  Adverse Effect on NLBI and
its  subsidiaries,  taken as a whole.  NLBI is a registered bank holding company
under the Bank Holding Company Act of 1956, as amended.

     2. Slatington is a national  banking  association  that is duly organized ,
validly  existing and in good  standing  under the laws of the United  States of

authority  (including  all  federal,   state,  local  and  foreign  governmental
authorizations)  to carry on their  respective  businesses as they are now being
conducted and to own their respective properties and assets.

     4. The authorized  capital stock of NLBI consists of ___________  shares of
NLBI Common Stock,  par value $10.00 per share, of which  ______________  shares

organized and existing as a  corporation,  is in good standing under the laws of
the jurisdiction in which it was organized,  and has adequate corporate power to

all such  subsidiaries has been validly issued,  is fully paid and nonassessable
and is  owned by NLBI or  Slatington,  free and  clear  of all  liens,  security
interests  and   encumbrances.   All  such   subsidiaries  are  organized  under
Pennsylvania  law and make no use of  fictitious  names in the  conduct of their
respective businesses.

     7.  Each of NLBI and  Slatington  has the  requisite  corporate  power  and
authority to execute and deliver the Agreement and to carry out the transactions
contemplated therein, and all corporate actions required to be taken by NLBI and
Slatington  to authorize  the  execution  and delivery of the  Agreement and the
performance  of the  transactions  contemplated  therein  have been  taken.  The
Agreement  has  been  duly  authorized,  executed  and  delivered  by  NLBI  and
Slatington and constitutes a valid and binding obligation of NLBI and Slatington
and is  enforceable  against  each 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.

     8. The execution,  delivery and  performance of the Agreement will not, and
the execution,  delivery and  performance of the Investment  Agreement will not,
and  the  consummation  of  the  transactions  contemplated  thereby  will  not,
constitute  (i) 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  NLBI or CNB (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  Merger,  (ii) a breach or  violation  of, or a
default under NLBI's articles of  incorporation,  the charter of Slatington,  or
the bylaws of either of them,  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 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 NLBI or  Slatington  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 either is a
party, or to which any of their 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 Merger.

     9. The consummation of the transactions  contemplated by the Agreement does
not require as to NLBI or Slatington  any approval,  consent or waiver under any
such law, rule,  regulation,  judgment,  decree,  order,  governmental permit or
license or , to our actual  knowledge,  the  approval,  consent or waiver of any
other party to any such agreement,  indenture or instrument,  other than (i) all
required approvals, consents and waivers of governmental


<PAGE>

authorities,  (ii) the  approval  of its  shareholders  referred  to in  Section
6.1(a).

     10. To our  actual  knowledge,  except as set forth in Annex  3.1(i) to the
Agreement,  there are no (i) civil, criminal or administrative  actions,  suits,
claims, hearings,  investigations or proceedings before any court,  governmental
agency or  otherwise  pending or, to the  knowledge  of  management,  threatened
against NLBI or Slatington or (ii)  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 NLBI or Slatington is aware that
could  reasonably be expected to result in any claims  against or obligations or
liabilities of either NLBI or Slatington),  that, alone or in the aggregate, are
reasonably  likely to have a Material Adverse Effect on NLBI or Slatington or to
hinder or delay,  in any  material  respect,  consummation  of the  transactions
contemplated by this Agreement.

     11. To our actual knowledge,  neither NLBI nor Slatington is 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  NLBI
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 NLBI  Regulatory  Agency  that such body is  contemplating
issuing or  requesting  (or is  considering  the  appropriateness  of issuing or
requesting)  any  such  order,  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 3
and 8 hereof.

Board of Directors
Northern Lehigh Bancorp, Inc.
502 Main Street
Slatington, PA  18080

Directors:

     You have requested our opinion,  as investment bankers, as to the fairness,
from a financial  point of view, of the terms of the proposed  acquisition  (the
"Merger") of Northern  Lehigh Bancorp,  Inc. and its sole subsidiary  ("Northern
Lehigh") by Harleysville National Corporation ("Harleysville").  Pursuant to the
Agreement  and Plan or  Reorganization  (the  "Agreement")  dated July 28,  1998
between   Northern   Lehigh  and  its  subsidiary  and   Harleysville   and  its
subsidiaries,  each share of Northern  Lehigh  common Stock  outstanding  at the
Effective  Time of Merger will be converted into and become the right to receive
3.57 shares of Harleysville Common Stock (the "Merger Consideration").

     Hopper Soliday & Co., Inc. ("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) Northern Lehigh's Annual
Reports and related  financial  information  for years ended  December  31, 1995
through December 31, 1997 and Northern  Lehigh's  Quarterly FDIC Call Report and
related  unaudited  financial  information for the period ending March 31, 1998;
ii) Harleysville's Annual Reports on Form 10-K and related financial information
for years ended December 31, 1996 and December 31, 1997 and Quarterly  Report on
Form  10-Q for the  period  ended  March  31,  1998;  iii)  certain  information
concerning  the  respective  businesses,  operations,  regulatory  condition and
prospects of Harleysville and Northern Lehigh,  including  financial  forecasts,
relating to the business,  earnings,  assets and prospects of  Harleysville  and
Northern  Lehigh,  furnished  to Hopper  Soliday by  Harleysville  and  Northern
Lehigh,  which Hopper  Soliday  discussed  with members of senior  management of
Harleysville  and Northern  Lehigh;  iv)  historical  market  prices and trading
activity for the Harleysville  Common Stock and Northern Lehigh Common Stock and
similar data for certain  publicly traded  companies which Hopper Soliday deemed
to be relevant; v) the

<PAGE>
Board of Directors
November 12, 1998
Page 2


results of operations of  Harleysville  and Northern Lehigh and similar data for
certain companies which Hopper Soliday deemed to be relevant;  vi) the financial
terms of the Merger  contemplated  by the 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  Agreement;  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
Northern Lehigh 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
Harleysville and Northern Lehigh as to the  reasonableness  and achievability of
the  financial  and  operating  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 Harleysville and
Northern  Lehigh  were  adequate  to cover such  losses.  We did not make any or
obtain any evaluations or appraisals of the assets of Harleysville  and Northern
Lehigh,  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
Northern Lehigh of the Merger Consideration.

     In   connection   with  this   opinion,   Hopper   Soliday   confirmed  the
appropriateness of its reliance on the analyses used to render its July 28, 1998
written opinion to the Board of Directors of Northern  Lehigh  Bancorp,  Inc. by
performing   procedures  to  update  certain   analyses  and  by  reviewing  the
assumptions  upon which such analyses  were based and the factors  considered in
connection therewith.

     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  Harleysville 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.

     We have acted as  financial  advisor to the Board of  Directors of Northern
Lehigh  in  connection  with  this  transaction  and will  receive a fee for our
services,  a substantial portion of which is contingent upon the consummation of
the Merger. In the past, Hopper Soliday has

<PAGE>
Board of Directors
November 12, 1998
Page 3


provided  financial  advisory services for Northern Lehigh and has received fees
for rendering of these services.

     It is understood  that this letter is for the  information  of the Board of
Directors of Northern  Lehigh and may not be used for any other purpose  without
our prior  written  consent,  except  that this  opinion  may be included in its
entirety in any filing with the Securities and Exchange Commission in connection
with the Merger. In addition, we express no opinion or recommendations as to how
the holders of Northern  Lehigh  Common Stock  should vote at the  stockholders'
meeting held in connection with the Merger.

     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 Northern Lehigh from a financial point of view.

Sincerely,

/s/ Hopper Soliday & Co., Inc.

          (1)  Except as otherwise provided in paragraph (2), the holders of the

               fixed to determine the shareholders  entitled to notice of and to
               vote at the meeting at which a plan  specified  in any of section

          (2)  Paragraph (1) shall not apply to and  dissenters  rights shall be
               available  without  regard  to the  exception  provided  in  that
               paragraph in the case of:

               (i)  Shares  converted by a plan if the shares are not  converted

                    corporation  or solely into such shares and money in lieu of
                    fractional shares.

               (ii) Shares  of  any   preferred  or  special  class  unless  the
                    articles,  the plan or the terms of the transaction  entitle
                    all  shareholders  of the class to vote  thereon and require
                    for the  adoption  of the  plan or the  effectuation  of the
                    transaction the affirmative  vote of a majority of the votes
                    cast by all shareholders of the class.

               (iii)Shares  entitled to dissenters  rights under section 1906(c)

     (3)  The  shareholders of a corporation  that acquires by purchase,  lease,
          exchange or other  disposition all or substantially all of the shares,
          property or assets of another  corporation  by the issuance of shares,
          obligations or otherwise,  with or without assuming the liabilities of
          the other  corporation and with or without the intervention of another
          corporation or other person, shall not be


<PAGE>

          entitled  to  the  rights  and  remedies  of  dissenting  shareholders
          provided in this subchapter regardless of the fact, if it be the case,
          that the acquisition was accomplished by the issuance of voting shares
          of the corporation to be outstanding immediately after the acquisition
          sufficient  to  elect  a  majority  or more  of the  directors  of the
          corporation.

     (c)  Grant of optional dissenters rights. The bylaws or a resolution of the
          board of directors  may direct that all or a part of the  shareholders
          shall have dissenters  rights in connection with any corporate  action
          or  other   transaction   that  would   otherwise   not  entitle  such
          shareholders to dissenters rights.

     (d)  Notice of dissenters rights.  Unless otherwise provided by statute, if
          a proposed  corporate action that would give rise to dissenters rights
          under  this   subpart  is   submitted  to  a  vote  at  a  meeting  of
          shareholders,  there shall be included in or enclosed  with the notice
          of meeting:

          (1)  a  statement  of the  proposed  action and a  statement  that the
               shareholders  have a right to dissent  and obtain  payment of the
               fair value of their  shares by  complying  with the terms of this
               subchapter; and

          (2) a copy of this subchapter.

     (e)  Other  statutes.  The  procedures  of this  subchapter  shall  also be
          applicable to any transaction described in any statute other than this
          part that  makes  reference  to this  subchapter  for the  purpose  of
          granting dissenters rights.

     (f)  Certain provisions of articles ineffective. This subchapter may not be
          relaxed by any provision of the articles.

     (g)  Cross  references.  See  sections  1105  (relating to  restriction  on
          equitable  relief),  1904 (relating to de facto  transaction  doctrine
          abolished) and 2512 (relating to dissenters rights procedure).

Section 1572. Definitions.

The  following  words and phrases  when used in this  subchapter  shall have the
meanings  given to them in this  section  unless the context  clearly  indicates
otherwise:

     "Corporation."  The  issuer of the  shares  held or owned by the  dissenter
     before the  corporate  action or the  successor  by merger,  consolidation,
     division,  conversion  or otherwise of that issuer.  A plan of division may
     designate which of the resulting  corporations is the successor corporation
     for the  purposes  of  this  subchapter.  The  successor  corporation  in a
     division  shall have sole  responsibility  for payments to  dissenters  and
     other liabilities under this subchapter except as otherwise provided in the
     plan of division.

<PAGE>


     "Dissenter." A shareholder or beneficial  owner who is entitled to and does
     assert  dissenters rights under this subchapter and who has performed every
     act required up to the time involved for the assertion of those rights.

     "Fair value." The fair value of shares  immediately before the effectuation
     of the corporate action to which the dissenter objects, taking into account
     all relevant  factors,  but excluding any  appreciation  or depreciation in
     anticipation of the corporate action.

     "Interest."  Interest from the effective date of the corporate action until
     the date of payment at such rate as is fair and equitable  under all of the
     circumstances,  taking into account all  relevant  factors,  including  the
     average rate currently paid by the corporation on its principal bank loans.

Section 1573. Record and beneficial holders and owners.

     (a)  Record  holders  of  shares.  A record  holder of shares of a business
          corporation may assert  dissenters  rights as to fewer than all of the
          shares  registered in his name only if he dissents with respect to all
          the shares of the same class or series  beneficially  owned by any one
          person and  discloses the name and address of the person or persons on
          whose  behalf  he  dissents.  In  that  event,  his  rights  shall  be
          determined as if the shares as to which he has dissented and his other
          shares were registered in the names of different shareholders.

     (b)  Beneficial  owners  of  shares.  A  beneficial  owner of  shares  of a
          business   corporation  who  is  not  the  record  holder  may  assert
          dissenters  rights with respect to shares held on his behalf and shall
          be  treated  as a  dissenting  shareholder  under  the  terms  of this
          subchapter if he submits to the corporation not later than the time of
          the  assertion of  dissenters  rights a written  consent of the record
          holder.  A  beneficial  owner may not dissent with respect to some but
          less than all shares of the same  class or series  owned by the owner,
          whether or not the shares so owned by him are registered in his name.

Section 1574. Notice of intention to dissent.

     If the  proposed  corporate  action is  submitted to a vote at a meeting of
     shareholders  of a business  corporation,  any person who wishes to dissent
     and  obtain  payment  of the fair  value of his  shares  must file with the
     corporation,  prior to the vote,  a written  notice of  intention to demand
     that he be paid the fair  value for his  shares if the  proposed  action is
     effectuated,  must  effect  no change in the  beneficial  ownership  of his
     shares from the date of such filing continuously through the effective date
     of the proposed  action and must refrain from voting his shares in approval
     of such action.  A dissenter who fails in any respect shall not acquire any
     right to payment of the fair  value of his  shares  under this  subchapter.
     Neither a proxy nor a vote  against the  proposed  corporate  action  shall
     constitute the written notice required by this section.


<PAGE>

Section 1575. Notice to demand payment.

     (a)  General  rule.  If the  proposed  corporate  action is approved by the
          required vote at a meeting of shareholders of a business  corporation,
          the corporation shall mail a further notice to all dissenters who gave
          due notice of intention  to demand  payment of the fair value of their
          shares and who refrained from voting in favor of the proposed  action.
          If the  proposed  corporate  action  is to be taken  without a vote of
          shareholders,  the corporation  shall send to all shareholders who are
          entitled  to  dissent  and  demand  payment of the fair value of their
          shares a notice of the adoption of the plan or other corporate action.
          In either case, the notice shall:

          (1)  State  where  and  when a  demand  for  payment  must be sent and
               certificates for  certificated  shares must be deposited in order
               to obtain payment.

          (2)  Inform holders of  uncertificated  shares to what extent transfer
               of  shares  will be  restricted  from the time  that  demand  for
               payment is received.

          (3)  Supply a form for  demanding  payment that includes a request for
               certification of the date on which the shareholder, or the person
               on whose behalf the  shareholder  dissents,  acquired  beneficial
               ownership of the shares.

          (4) Be accompanied by a copy of this subchapter.

     (b)  Time for  receipt of demand for  payment.  The time set for receipt of
          the demand and deposit of  certificated  shares shall be not less than
          30 days from the mailing of the notice.

Section 1576. Failure to comply with notice to demand payment, etc.

     (a)  Effect of failure of  shareholder  to act. A shareholder  who fails to
          timely demand payment,  or fails (in the case of certificated  shares)
          to timely deposit  certificates,  as required by a notice  pursuant to
          section 1575 (relating to notice to demand payment) shall not have any
          right under this  subchapter  to receive  payment of the fair value of
          his shares.

     (b)  Restriction  on   uncertificated   shares.   If  the  shares  are  not
          represented by  certificates,  the business  corporation  may restrict
          their  transfer  from the time of receipt of demand for payment  until
          effectuation  of the  proposed  corporate  action  or the  release  of
          restrictions  under the terms of section 1577(a)  (relating to failure
          to effectuate corporate action).

     (c)  Rights retained by  shareholder.  The dissenter shall retain all other
          rights  of  a   shareholder   until  those   rights  are  modified  by
          effectuation of the proposed corporate action.

<PAGE>

Section 1577. Release of restrictions or payment for shares.

     (a)  Failure to effectuate corporate action.  Within 60 days after the date
          set for demanding payment and depositing certificates, if the business
          corporation  has not  effectuated the proposed  corporate  action,  it
          shall return any  certificates  that have been  deposited  and release
          uncertificated shares from any transfer restrictions imposed by reason
          of the demand for payment.

     (b)  Renewal of notice to demand payment.  When uncertificated  shares have
          been released from transfer  restrictions  and deposited  certificates
          have been returned,  the  corporation may at any later time send a new
          notice  conforming to the  requirements  of section 1575  (relating to
          notice to demand payment), with like effect.

     (c)  Payment of fair value of shares.  Promptly after  effectuation  of the
          proposed  corporate  action,  or upon  timely  receipt  of demand  for
          payment if the  corporate  action has already  been  effectuated,  the
          corporation  shall either remit to dissenters who have made demand and
          (if their shares are certificated)  have deposited their  certificates
          the amount that the corporation  estimates to be the fair value of the
          shares,  or give written notice that no remittance  under this section
          will be made. The remittance or notice shall be accompanied by:

          (1)  The closing  balance  sheet and statement of income of the issuer
               of the shares  held or owned by the  dissenter  for a fiscal year
               ending not more than 16 months  before the date of  remittance or
               notice  together  with the  latest  available  interim  financial
               statements.

          (2)  A statement  of the  corporation's  estimate of the fair value of
               the shares.

          (3)  A notice  of the right of the  dissenter  to  demand  payment  or
               supplemental  payment,  as the case may be, accompanied by a copy
               of this subchapter.

     (d)  Failure to make payment.  If the corporation does not remit the amount
          of its  estimate  of the  fair  value of the  shares  as  provided  by
          subsection  (c),  it shall  return  any  certificates  that  have been
          deposited  and  release   uncertificated   shares  from  any  transfer
          restrictions  imposed  by  reason  of  the  demand  for  payment.  The
          corporation  may make a  notation  on any such  certificate  or on the
          records of the corporation relating to any such uncertificated  shares
          that such  demand  has been  made.  If shares  with  respect  to which
          notation has been so made shall be  transferred,  each new certificate
          issued   therefor   or  the  records   relating  to  any   transferred
          uncertificated shares shall bear a similar notation, together with the
          name of the  original  dissenting  holder or owner of such  shares.  A
          transferee  of such  shares  shall not  acquire by such  transfer  any
          rights in the corporation other than those that the original dissenter
          had after making demand for payment of their fair value.


<PAGE>

Section 1578. Estimate by dissenter of fair value of shares.

     (a)  General rule. If the business corporation gives notice of its estimate
          of the fair value of the shares,  without  remitting  such amount,  or
          remits  payment of its  estimate  of the fair  value of a  dissenter's
          shares as  permitted by section  1577(c)  (relating to payment of fair
          value of shares) and the dissenter  believes that the amount stated or
          remitted is less than the fair value of his shares, he may send to the
          corporation  his own  estimate of the fair value of the shares,  which
          shall be deemed a demand for payment of the amount or the deficiency.

     (b)  Effect of failure to file estimate.  Where the dissenter does not file
          his own estimate under subsection (a) within 30 days after the mailing
          by the corporation of its remittance or notice, the dissenter shall be
          entitled  to no more than the amount  stated in the notice or remitted
          to him by the corporation.

Section 1579. Valuation proceedings generally.

     (a) General rule. Within 60 days after the latest of:

          (1)  effectuation of the proposed corporate action;

          (2)  timely  receipt of any  demands for payment  under  Section  1575
               (relating to notice to demand payment); or

          (3)  timely  receipt  of  any  estimates   pursuant  to  section  1578
               (relating to estimate by dissenter of fair value of shares);

          if any demands for payment remain unsettled,  the business corporation
          may file in court an application  for relief  requesting that the fair
          value of the shares be determined by the court.

     (b)  Mandatory joinder of dissenters.  All, dissenters,  wherever residing,
          whose  demands  have not been  settled  shall be made  parties  to the
          proceeding  as in an  action  against  their  shares.  A  copy  of the
          application shall be served on each such dissenter.  If a dissenter is
          a nonresident, the copy may be served on him in the manner provided or
          prescribed  by or pursuant to 42 Pa.C.S.  Ch. 53 (relating to bases of
          jurisdiction and interstate and international procedure).

     (c)  Jurisdiction  of the court.  The  jurisdiction  of the court  shall be
          plenary and  exclusive.  The court may appoint an appraiser to receive
          evidence  and  recommend a decision  on the issue of fair  value.  The
          appraiser  shall have such power and  authority as may be specified in
          the order of appointment or in any amendment thereof.


<PAGE>
     (d)  Measure  of  recovery.  Each  dissenter  who is made a party  shall be
          entitled  to recover  the amount by which the fair value of his shares
          is found to exceed  the  amount,  if any,  previously  remitted,  plus
          interest.

     (e)  Effect  of  corporation's   failure  to  file   application.   If  the
          corporation  fails to file an  application  as provided in  subsection
          (a), any dissenter  who made a demand and who has not already  settled
          his  claim  against  the  corporation  may  do so in the  name  of the
          corporation  at any time  within 30 days after the  expiration  of the
          60-day period. If a dissenter does not file an application  within the
          30-day period, each dissenter entitled to file an application shall be
          paid the corporation's estimate of the fair value of the shares and no
          more,  and may bring an action to recover  any  amount not  previously
          remitted.

Section 1580. Costs and expenses of valuation proceedings.

     (a)  General rule. The costs and expenses of any  proceeding  under section
          1579  (relating to valuation  proceedings  generally),  including  the
          reasonable compensation and expenses of the appraiser appointed by the
          court,  shall be  determined  by the court and  assessed  against  the
          business  corporation  except that any part of the costs and  expenses
          may be apportioned and assessed as the court deems appropriate against
          all or some of the  dissenters  who are  parties  and whose  action in
          demanding   supplemental  payment  under  section  1578  (relating  to
          estimate by  dissenter  of fair value of shares) the court finds to be
          dilatory, obdurate, arbitrary, vexatious or in bad faith.

     (b)  Assessment  of counsel  fees and expert  fees where lack of good faith
          appears.  Fees  and  expenses  of  counsel  and  of  experts  for  the
          respective  parties may be  assessed  as the court  deems  appropriate
          against the  corporation  and in favor of any or all dissenters if the
          corporation  failed to comply  substantially  with the requirements of
          this subchapter and may be assessed  against either the corporation or
          a dissenter,  in favor of any other party, if the court finds that the
          party  against whom the fees and  expenses  are assessed  acted in bad
          faith or in a dilatory,  obdurate,  arbitrary or  vexatious  manner in
          respect to the rights provided by this subchapter.

     (c)  Award of fees for  benefits  to other  dissenters.  If the court finds

Item 22. Undertakings.

     (a)  

     1.   The undersigned Registrant hereby undertakes as follows:

<PAGE>
          (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 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

<PAGE>
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  Corporation/Northern  Lehigh Bancorp, Inc.
          Our File No. 649-98

Gentlemen:

     In connection with the proposed  offering of up to 515,858 shares of common
stock, par value $1.00 per share (the "Common Stock"), by Harleysville  National
Corporation (the "Company"),  covered by the Company's Registration Statement on
Form S-4 (the  "Registration  Statement") filed with the Securities and Exchange
Commission  under the  Securities  Act of 1933, as amended,  with respect to the
Common Stock, we, as special counsel to the Company, have reviewed:

1.   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 July 28, 1998, by and
     among, the Company,  Harleysville  National  Corporation  North,  Inc., The
     Citizens National Bank of Lansford,  Northern Lehigh Bancorp,  Inc. and The
     Citizens National Bank of Slatington (the "Agreement");

5.   The Registration Statement; and

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  has  been  duly  incorporated   under  the  laws  of  the
Commonwealth of Pennsylvania  and is validly existing and in good standing under
the laws of the Commonwealth; and

<PAGE>

     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 thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,

Dear Shareholder:

     You are  invited to attend a special  meeting of the  shareholders  of your
company,  Northern  Lehigh  Bancorp,  Inc., the holding company for The Citizens
National  Bank of  Slatington.  This  special  meeting will be held on Thursday,
January 14, 1999,  at 1:00 p.m.,  at 510 Main  Street,  (next to the Bank's Main
Office),  Slatington,  Pennsylvania 18080. The main purpose of the meeting is to
vote on the  merger of  Northern  Lehigh  Bancorp,  Inc.  with a  subsidiary  of
Harleysville   National   Corporation,   a  bank  holding   company  located  in
Harleysville,  Montgomery County, Pennsylvania.  If the merger is completed, you
will receive 3.57 shares of Harleysville  National  Corporation  common stock in
exchange for each of your shares of Northern Lehigh  Bancorp.  Inc. The exchange
of Northern Lehigh stock for Harleysville National Corporation stock (other than
cash  paid  for  fractional   shares)  will  be  tax-free  to  Northern   Lehigh
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 Northern Lehigh Bancorp,  Inc.  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 Northern  Lehigh  Bancorp,  Inc.  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   Francis  P.  Burbidge,   First  Vice  President  of  the
Corporation, telephone (610) 767-3887.

     Hopper Soliday & Co.,  Inc.,  Northern  Lehigh  Bancorp,  Inc's  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 shareholders and urges you to vote for the merger.

                                               Sincerely yours,

                          NOTICE OF SPECIAL MEETING OF
                   SHAREHOLDERS TO BE HELD ON JANUARY 14, 1999



     NOTICE IS HEREBY GIVEN that a Special  Meeting of  Shareholders of Northern
Lehigh  Bancorp,  Inc.  will be held at 1:00 p.m.,  Eastern  Standard  Time,  on
Thursday,  January 14, 1999, at 510 Main Street, (next to the Main Office of The
Citizens  National  Bank of  Slatington),  Slatington,  Pennsylvania  18080.  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
July 28,  1998 by and  among  Harleysville  National  Corporation,  Harleysville
National  Corporation  North,  Inc.,  The  Citizens  National  Bank of Lansford,
Northern Lehigh Bancorp, Inc. and The Citizens National Bank of Slatington.  The
agreement   provides  that  Northern  Lehigh  Bancorp,   Inc.  will  merge  with
Harleysville National Corporation North, Inc. and, immediately  thereafter,  The
Citizens  National Bank of Slatington will merge with The Citizens National Bank
of Lansford.  Upon completion of the merger, each Northern Lehigh Bancorp,  Inc.
shareholder will have the right to receive 3.57 shares of Harleysville  National
Corporation  common stock, par value $1.00 per share, in exchange for each share
of common stock of Northern  Lehigh  Bancorp,  Inc., par value $10.00 per share,
held by the shareholder;

     2.  Postponement  or  adjournment  of  the  meeting  to a  later  date,  if
necessary,  to permit the  solicitation of additional  proxies in the event that
there  are not  sufficient  votes  at the time of the  meeting  to  approve  the
agreement and the merger; and

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

     We may take action on any one of these proposals 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 Northern Lehigh Bancorp, Inc. at
the close of business on Monday,  November 16, 1998, 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 Northern  Lehigh  Bancorp,  Inc. 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

<PAGE>
person or by sending in a completed proxy, is important. We need the affirmative
vote of at least 66 2/3% 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 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 Northern  Lehigh
Bancorp, Inc. Your ballot at the meeting will replace your proxy.

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


                                          By Order of the Board of Directors,


                                          /s/ Joseph G. Bechtel
