(1)  Based on the maximum number of shares of the Registrant's common stock that
     may be issued in connection with the proposed merger (the "Merger") of
     Elverson National Bank ("Elverson") with and into a subsidiary of the
     Registrant. In accordance with Rule 416, this Registration Statement shall
     also register any additional shares of the Registrant's common stock which

     dividends or similar transactions, as provided by the agreement relating to
     the Merger.

(2)  Estimated solely for purposes of calculating the registration fee. Computed
     in accordance with Rule 457(f) (1), based on the average of the bid and
     asked price per share of common stock of Elverson on October 12, 1998 of
     $31, and based on 2,597,995 shares of Elverson common stock to be exchanged
     in the Merger and unexercised options to purchase 43,890 shares of Elverson
     common stock. Pursuant to Rule 457(b), the required fee is reduced by the
     $17,436.44 filing fee paid at the time of filing preliminary proxy
     materials in connection with this transaction on September 25, 1998.

(3)  Prior to the occurrence of certain events, the stock purchase rights will
     not be evidenced separately from the common stock.

The Merger

         Terms of the Merger

         On the Effective Date of the Merger, as defined below, each outstanding
share of Elverson  Common  Stock  (other  than any  dissenting  shares)  will be
automatically  converted into, and become a right to receive,  1.46875 shares of
NPB Common Stock (the "Exchange Ratio"),  provided that the NPB Market Value (as
hereinafter defined) is greater than or equal to $24.30. If the NPB Market Value
is  less  than  $24.30,   the  Exchange   Ratio  will  be  adjusted  in  certain
circumstances  and the  Exchange  Ratio may be adjusted at NPB's  discretion  in
other circumstances as follows:  (a) if the NPB Market Value is less than $24.30
but either (i) the NPB Market  Value is greater  than or equal to $21.60 or (ii)
the NPB Market  Value  Quotient  (as  hereinafter  defined) is not less than the
Index Group Standard (as hereinafter  defined) by 5% or more,  each  outstanding
share of Elverson Common Stock (other than any dissenting shares or any treasury
shares) will be converted into, and become a right to receive, 1.5 shares of NPB
Common Stock; and (b) if (i) the NPB Market Value is less than $21.60,  (ii) the
NPB Market Value  Quotient is less than the Index Group  Standard by 5% or more,
and (iii) Elverson has properly  elected to terminate the Merger  Agreement (see
"The Merger--Termination;  Possible Exchange Ratio Increase"), NPB will have the
option to increase the Exchange Ratio to 1.5625 and thereby  nullify  Elverson's
election to terminate the Merger Agreement.

         As further  described  herein under "The  Merger--Terms of the Merger,"
for  purposes  of the  adjustment  described  above and the right of Elverson to
terminate the Merger  Agreement as described  above,  (a) the "NPB Market Value"
will be  calculated by averaging the closing sale price of a share of NPB Common
Stock over a period of 20 trading days ending on the trading day that is 31 days
prior to the Elverson  Meeting,  (b) the "NPB Market Value Quotient" will be the
quotient obtained by dividing the NPB Market Value by $27.00, and (c) the "Index
Group  Standard"  will be the  quotient  obtained by dividing the average of the
closing  sale  prices of a group of bank and thrift  holding  companies  (on any
date,  the "Index  Price") over the same 20 trading day period used to calculate
NPB Market Value by the Index Price on July 20, 1998.

         The number of shares of NPB  Common  Stock  issuable  in  exchange  for
outstanding  shares of Elverson Common Stock will be further adjusted to prevent
dilution in the event of  additional  stock splits,  reclassifications  or other
similar events.

          NPB will in all events pay cash to  Elverson  shareholders  in lieu of
issuing fractional shares of NPB Common Stock.

         In  connection  with the Merger,  all  outstanding  options to purchase
Elverson Common Stock issued under  Elverson's stock option plans generally will
be converted on the Effective  Date into options to acquire shares of NPB Common
Stock.  On and after the Effective  Date,  each such option shall  represent the
right to  acquire  that  number of shares of NPB Common  Stock  equal to (a) the
number of shares of Elverson  Common Stock covered by such option  multiplied by
(b) the Exchange Ratio (as it may be adjusted).  The exercise price per share of
each such option shall be (a) its stated exercise price per share divided by (b)
the Exchange Ratio (as it may be adjusted).

         The  Effective  Date  will be the date on which all  conditions  to the
Merger have been fulfilled or waived or as soon as practicable  thereafter.  ENB
and NPB currently anticipate that the Effective Date will occur in early 1999.

that,  as of the  date of such  opinion,  and  subject  to the  assumptions  and
considerations set forth therein,  the financial terms of the Merger are fair to
Elverson  shareholders  from a  financial  point  of view.  A copy of  Berwind's
opinion is attached to this Proxy  Statement/Prospectus  as Annex B. The opinion
should be read in its entirety  with respect to the  assumptions  made and other

         Accounting Treatment

         The  Merger is  intended  to  qualify  as a pooling  of  interests  for
accounting  and  financial  reporting  purposes.  See  "The   Merger--Accounting
Treatment."

         Federal Income Tax Consequences

         The  obligation of each of NPB and Elverson to consummate the Merger is
conditioned  upon the receipt of an opinion from its respective  special counsel
or independent certified public accountants substantially to the effect that the
Merger will be treated,  for federal  income tax purposes,  as a  reorganization
within the meaning of Section  368(a) of the Internal  Revenue Code of 1986,  as
amended,  and that no gain or loss will be recognized by the holders of Elverson
Common  Stock in  connection  with the Merger,  except to the extent of any cash
received  in  lieu  of  a  fractional  share  of  NPB  Common  Stock.  See  "The
Merger--Certain Federal Income Tax Consequences."

         Conditions to the Merger; Regulatory Approvals

         The  obligations of NPB and Elverson to complete the Merger are subject
to various  conditions that are usual and customary in  transactions  similar to
the Merger, including,  among other things, obtaining regulatory approval (which
has been obtained), obtaining approvals of both the shareholders of Elverson and
the shareholders of NPB, and obtaining  opinions that the Merger will qualify as
a tax-free  reorganization  for federal  income tax purposes and as a pooling of
interests  for financial  accounting  purposes.  There is no assurance  that all
conditions  to  the  Merger  will  be  satisfied.  See  "The  Merger--Regulatory
Approvals" and "The Merger--Conditions to the Merger."

         Termination

         The  Merger  Agreement  may be  terminated  at any  time  prior  to the
Effective  Date by mutual  consent of NPB and Elverson or by either party if (i)
the other party, in any material respect, breaches any representation, warranty,
covenant or other  obligation  contained in the Merger Agreement and such breach
has not been cured  within 30 days from the date  written  notice of such breach
was given to the party  committing  the  breach,  (ii) the closing of the Merger
shall not have  occurred on or before  February 28, 1999,  unless the failure of
such  occurrence  shall be due to the failure of the party  seeking to terminate
the  Merger  Agreement  to  perform or observe  any  agreements  required  to be
performed  by such  party on or  before  the  closing,  (iii) if any  regulatory
authority  whose  approval or consent is required  for the  consummation  of the
Merger  issues a definitive  written  denial of such approval or consent and the
time periods for appeals or requests for  reconsideration  have expired; or (iv)
shareholders  of Elverson or NPB do not  approve the Merger  Agreement  at their
respective Meetings.

         In addition,  Elverson may terminate  the Merger  Agreement at any time
during the ten-day period  following the  Determination  Date (which,  under the
Merger Agreement,  will be the trading day that is 31 days prior to the Elverson
Meeting),  if both (a) the NPB Market  Value is less than $21.60 and (b) the NPB
Market  Value  Quotient  is less than the Index  Group  Standard  by 5% or more,
subject to NPB's right to nullify such  termination  of the Merger  Agreement by
increasing the Exchange Ratio to 1.5625.  Elverson may also terminate the Merger
Agreement  at any time during the ten-day  period  following  the  Determination
Date, if the NPB Market Value is less than $20.25.

         Elverson  may  terminate  the  Merger  Agreement  if  NPB or any of its
subsidiaries  enters into an agreement with a third party  concerning any merger
of NPB with or into such third party or the  acquisition of all of NPB's assets,
or if any person or entity acquires 19.9% or more of the  outstanding  shares of
NPB Common Stock. Finally, Elverson may terminate the Merger Agreement following
receipt of an Acquisition  Proposal (see "The  Merger--No  Solicitation of Other
Transactions"),  but only if the Elverson  Board of Directors  has  concluded in
good faith after  consultation  with its legal and financial  advisors that such
Acquisition  Proposal,  if consummated pursuant to its terms, would result in an
alternative  transaction  more  favorable to  Elverson's  shareholders  than the
Merger,  in which case  Elverson  would owe an  immediately  payable  $5,000,000
termination fee to NPB. See "The Merger--Termination Fees".

         Management and Operations After the Merger

         NP Bank, as the surviving  bank in the Merger (the  "Surviving  Bank"),
will establish a separate  banking  division called  "Elverson  National Bank, A
Division of National  Penn Bank" (the  "Elverson  Division")  and the  "Elverson
Division  Board of  Directors"  (the  "Elverson  Division  Board") to advise the
Surviving Bank from time to 

                                       12

time regarding sales,  marketing and expansion of the Elverson Division. NPB has
agreed to operate the Elverson Division and maintain the Elverson Division Board
in existence for at least five years after the Effective Date, except in certain
circumstances set forth in the Merger Agreement.

         The  directors  and  executive  officers of NP Bank prior to the Merger
will  continue,  in their  respective  capacities,  as directors  and  executive
officers of the  Surviving  Bank.  In addition,  two persons  (each an "Elverson
Nominee")  proposed by Elverson's Board of Directors and approved by NPB will be
elected as directors of the Surviving  Bank. NPB and NP Bank have agreed to take
all steps  necessary  to ensure that each  Elverson  Nominee  (or any  successor
selected by the Elverson  Division  Board and approved by NPB) is  re-elected to
the Surviving Bank's Board of Directors for each of the five years following the
Effective  Date, if he is in office as a director of the  Surviving  Bank on the
annual  election  dates.  The  selection of the  Elverson  Nominees has not been
finalized pursuant to the Merger Agreement. Glenn E. Moyer, President and CEO of
ENB and a  member  of the ENB  Board,  will  become  President  of the  Elverson
Division and President of the Berks County and  Montgomery  County regions of NP
Bank. Mr. Moyer will also become an Executive  Vice  President of NP Bank,  with
additional corporate responsibilities.

         Upon  completion  of the Merger and  subject  to all  applicable  legal
requirements,  NPB has  agreed  that its Board of  Directors  will  appoint  two
persons  (each an  "Elverson  NPB  Nominee")  proposed  by  Elverson's  Board of
Directors  and approved by NPB to serve as directors of NPB  effective as of the
Effective Date for terms  expiring in April 2000, and April 2001,  respectively.
NPB has also  agreed  to cause  each  Elverson  NPB  Nominee  (or any  successor
selected by the Elverson  Division Board and approved by NPB) to be re-nominated
for at least one additional  three-year  term  thereafter.  The selection of the
Elverson NPB Nominees has not been finalized pursuant to the Merger Agreement.

         Interest of Certain Persons in the Merger

         Certain directors and officers of Elverson have interests in the Merger
in  addition  to any  interests  they  may  have  as  shareholders  of  Elverson
generally.  These include NPB's agreement to indemnify  Elverson's  officers and
directors  against  all  losses,  claims and  damages  arising out of actions or
omissions or alleged actions or omissions occurring at or prior to the Effective
Date and to provide insurance covering  Elverson's  officers and directors for a
period of six years from the  Effective  Date.  In addition,  as provided in the
Elverson  1996 Stock  Incentive  Plan,  as of the date of the  Merger  Agreement
certain  outstanding  options to acquire ENB Common  Stock held by the  officers
became 100 percent vested.  All outstanding  options to acquire ENB Common Stock
will be  converted  into  options to purchase  NPB Common  Stock.  Further,  all
benefits  accrued  under the Elverson  retirement  plans will become 100 percent
vested as of the Effective Date and benefits accrued under the Elverson deferred
compensation  arrangement  will  become  immediately  distributable.   See  "The
Merger--Interests  of Certain Persons in the Merger."  Following the Merger, two
persons  selected by the Board of  Directors  of ENB and approved by NPB will be
appointed as directors of NPB and two persons selected by the Board of Directors
of ENB and approved by NPB will be appointed as directors of the Surviving Bank.
Additionally,  the Surviving  Bank will  undertake to create a separate  banking
division which will have a board of directors  composed primarily of the present
Elverson  Board of  Directors  and whose  primary  purpose will be to advise the
Surviving Bank from time to time regarding sales, marketing and expansion of the
separate banking  division.  Mr. Moyer will become the President of the Elverson
Division and of the Berks County and Montgomery  County regions and an Executive
Vice  President of NP Bank,  with  additional  corporate  responsibilities.  Mr.
Moyer's change of control  agreement with ENB provides that if his employment is
terminated  due to a change of control,  he will receive a payment  equal to his
salary for the preceding  twelve month  period.  See "The  Merger--Terms  of the
Merger,"  "The  Merger--Management  and  Operations  After the  Merger" and "The
Merger--Interests of Certain Persons in the Merger."

         Comparison of Shareholders' Rights

         NPB is a  Pennsylvania  corporation  subject to the  provisions  of the
Pennsylvania Business Corporation Law of 1988, as amended (the "BCL");  Elverson
is a national banking association governed by the National Bank Act (the "NBA").
Upon completion of the Merger, shareholders of Elverson will become shareholders
of NPB,  and  their  rights  as such  will be  governed  by the BCL and by NPB's
articles of  incorporation  and bylaws.  The rights of  shareholders  of NPB are
different in certain  respects from the rights of shareholders of Elverson.  The
most  significant of these  differences  include the  following:  (i) NPB has in
effect a shareholder rights plan,  pursuant to which holders of NPB Common Stock
are  entitled  under  certain  circumstances  relating  to an attempt to acquire
control of NPB to acquire  shares of NPB  Common  Stock or stock of a  potential
acquiror at a  substantially  reduced price  (Elverson has not adopted a similar
shareholder   rights  plan);  (ii)  certain  provisions  of  NPB's  articles  of
incorporation  are designed to deter a non-negotiated  attempt to obtain control
of NPB and certain provisions of the BCL are similarly intended for Pennsylvania
corporations   generally;   and  (iii)  provisions  of  Elverson's  articles  of
association  grant its  shareholders  pre-emptive  rights to purchase  shares of
Elverson  Common  Stock  (NPB  shareholders  have no  pre-emptive  rights).  See
"Comparison of Shareholders' Rights."

         Appraisal Rights of Dissenting Shareholders

         As required by the NBA, any Elverson  shareholder who has voted against
the Merger Agreement at the Elverson Meeting, or has given notice to Elverson in
writing at or prior to the Elverson Meeting that such shareholder  dissents from
the Merger,  shall be entitled to receive the "value" of the shares held by that
shareholder  at the time the Merger  Agreement  is approved by the Office of the
Comptroller of the Currency (the "OCC"), upon written request made to NPB at any
time within 30 days following the Effective  Date,  accompanied by the surrender
of such shareholder's Elverson stock certificates.  The relevant portions of the
statutory dissenters procedures are attached to this Proxy  Statement/Prospectus
as Annex D. Elverson  shareholders  electing to exercise their dissenters rights
under  the  National  Bank  Act may not  vote for the  Merger  Agreement.  If an
Elverson  shareholder returns a signed proxy but does not specify a vote against
the Merger Agreement or does not give a direction to abstain,  the proxy will be
voted for the Merger  Agreement,  which  will have the  effect of  waiving  that
shareholder's  dissenters  rights.  Failure to take any of the steps required by
the  National  Bank  Act  on a  timely  basis  may  result  in the  loss  of the
shareholder's dissenters rights. See "The Merger--Appraisal Rights of Dissenting
Shareholders."

         Shareholders of NPB do not have any statutory dissenters rights.

(4) Effective  January 1, 1997, NPB adopted SFAS No. 128,  "Earnings Per Share,"
which  eliminates  primary and fully  diluted  earnings  per share and  requires
presentation  of basic and diluted  earnings per share in  conjunction  with the
disclosure of the  methodology  used in computing  such earnings per share.  Net
income per share  calculations  for prior  periods have been restated to reflect
the  adoption  of SFAS No.  128.  Basic net  income  per share is based upon the
respective weighted average number of shares of NPB Common Stock outstanding, as
follows:  13,199,215  (June 30, 1998);  13,358,435  (June 30, 1997);  13,339,318
(December 31, 1997);  13,349,418  (December 31, 1996);  13,282,685 (December 31,
1995);  13,260,403  (December  31, 1994) and  13,216,043  (December  31,  1993).
Diluted net income per share in all years presented gives effect to the dilution
resulting  from stock options  granted by NPB or acquired  companies.  Per share
amounts in all years have been  adjusted  to reflect  retroactively  prior stock
dividends  and splits.  NPB declared a 5-for-4  stock split  payable on July 31,
1998.  All weighted  average  shares and per share data have been  retroactively
restated.

standard  had  no  effect  on  Elverson's   financial  position  or  results  of
operations. There are no investment securities held for trading purposes.

(2) Effective  January 1, 1993,  Elverson adopted SFAS No. 109,  "Accounting for

(3) Interim  ratios have been  annualized  for  purposes of  comparability  with
year-end data.

(4)  Effective  January 1, 1997,  Elverson  adopted SFAS No. 128,  "Earnings Per
Share,"  which  eliminates  primary  and fully  diluted  earnings  per share and
requires  presentation  of basic and diluted  earnings per share in  conjunction
with the  disclosure  of the  methodology  used in computing  such  earnings per
share. Net income per share calculations for prior periods have been restated to
reflect the  adoption of SFAS No. 128.  Basic net income per share is based upon
the  respective  weighted  average  number of shares of  Elverson  Common  Stock
outstanding,  as follows:  2,591,956 (June 30, 1998); 2,563,920 (June 30, 1997);

(December 31, 1995);  2,467,595  (December 31, 1994) and 2,425,065 (December 31,
1993).  Diluted net income per share in all years  presented gives effect to the
dilution  resulting from stock options granted by Elverson.  The effect of stock
options on diluted  earnings per share for Elverson is immaterial and results in
the same amount reported as basic earnings per share for all periods  presented.
Per share amounts in all years have been adjusted to reflect retroactively prior
stock dividends and splits.  All weighted average shares and per share data have
been retroactively restated.

         It is not expected  that any matter other than that  referred to herein
will be brought  before the Elverson  Meeting.  If,  however,  other matters are
properly  presented,  the persons named as proxies will vote in accordance  with
their best judgment with respect to such matters.

         If a quorum is not  obtained,  or if fewer shares are voted in favor of
approval of the Merger  Agreement  than the number  required for  approval,  the
Elverson  Meeting  may be  adjourned  for the  purpose of  obtaining  additional
proxies or votes or for any other purpose, and, at any subsequent reconvening of
the  Elverson  Meeting,  all  proxies  will be voted in the same  manner as such
proxies would have been voted at the original  convening of the meeting  (except
for any proxies which have  theretofore  effectively been revoked or withdrawn),
notwithstanding  that  they may have been  effectively  voted on the same or any
other matter at a previous meeting.

         NPB. All shares  represented by properly  executed  proxies received in
time  for the NPB  Meeting  will be  voted  at the  NPB  Meeting  in the  manner
specified by the holders  thereof,  unless such proxies are revoked prior to the
vote. Properly executed proxies which do not contain voting instructions will be
voted in favor of the Merger Agreement.

         It is not expected  that any matter other than that  referred to herein
will be brought before the NPB Meeting. If, however,  other matters are properly
presented,  the persons named as proxies will vote in accordance with their best
judgment with respect to such matters.

         If a quorum is not  obtained,  or if fewer shares are voted in favor of
approval of the Merger Agreement than the number required for approval,  the NPB
Meeting may be  adjourned  for the purpose of  obtaining  additional  proxies or
votes or for any other purpose,  and, at any  subsequent  reconvening of the NPB
Meeting, all proxies will be voted in the same manner as such proxies would have
been voted at the  original  convening  of the  meeting  (except for any proxies
which have theretofore  effectively been revoked or withdrawn),  notwithstanding
that they may have been  effectively  voted on the same or any other matter at a
previous meeting.

Effect of Abstentions and Broker Non-Votes

         Elverson.  Abstention  from  voting  on  the  Merger  Agreement  may be
specified on an executed  proxy.  Such  abstentions  will be  considered  shares
present and entitled to vote at the Elverson Meeting, but will not be counted as
votes cast at the Elverson Meeting.

         Under  the  applicable  rules of the New York  Stock  Exchange  and the
National Association of Securities Dealers, Inc., brokers and/or members, as the
case may be, who hold shares in street name for customers who are the beneficial
owners of such shares are prohibited from giving a proxy to vote such customers'
shares with respect to the approval of the Merger  Agreement,  in the absence of
specific instructions from such customers ("broker non-votes"). Broker non-votes
will not be counted as votes cast at the Elverson Meeting.

         ABSTENTIONS BY ELVERSON'S  SHAREHOLDERS AND BROKER NON-VOTES (RESULTING
FROM FAILURE TO GIVE VOTING  INSTRUCTIONS) WILL HAVE THE EFFECT OF VOTES AGAINST
THE MERGER AGREEMENT.

         NPB. Abstention from voting on the Merger Agreement may be specified on
an executed  proxy.  Such  abstentions  will be  considered  shares  present and
entitled  to vote at the NPB  Meeting,  but will not be counted as votes cast at
the NPB Meeting.

         Broker  non-votes with respect to the Merger Agreement also will not be
counted as votes cast at the NPB Meeting.

         Because approval of the Merger Agreement  requires the affirmative vote
of a  majority  of  all  votes  cast  at the  NPB  Meeting,  abstentions  by NPB
shareholders  and broker non-votes will have no effect on approval of the Merger
Agreement by NPB shareholders.

Revocability of Proxies

         The  grant of a proxy on the  enclosed  Elverson  or NPB form  does not
preclude an Elverson shareholder or an NPB shareholder from voting in person. An
Elverson  shareholder or NPB shareholder may revoke a proxy at any time prior to
its exercise by (i) filing with the  Secretary  of  Elverson,  in the case of an
Elverson shareholder, or the Secretary of NPB, in the case of NPB shareholder, a
duly executed revocation of proxy, (ii) submitting a duly executed proxy bearing
a later date; or (iii) appearing at the applicable  Meeting and voting in person
at such  Meeting.  Attendance  at the  applicable  Meeting  will not,  in and of
itself, constitute revocation of a proxy.

Solicitation of Proxies

         Elverson and NPB will each bear the cost of the solicitation of proxies
from its own  shareholders,  except that Elverson and NPB will share equally the
cost of printing  and mailing  this Proxy  Statement/Prospectus.  In addition to
solicitation by mail, the directors, officers, and employees of Elverson and NPB
and their subsidiaries may solicit proxies from their respective shareholders by
telephone   or  telegram   or  in  person   without   compensation   other  than
reimbursements  for their actual expenses.  Arrangements  will also be made with
brokerage  houses  and  other  custodians,  nominees,  and  fiduciaries  for the
forwarding of proxy solicitation  material to beneficial owners of stock held of
record by such persons,  and Elverson and NPB will  reimburse  such  custodians,
nominees  and  fiduciaries  for  their  reasonable   out-of-pocket  expenses  in
connection therewith.

         ELVERSON  SHAREHOLDERS  SHOULD NOT SEND STOCK  CERTIFICATES  WITH THEIR
PROXY CARDS.  AS  DESCRIBED  BELOW UNDER THE CAPTION  "THE  MERGER--EXCHANGE  OF
ELVERSON STOCK  CERTIFICATES."  EACH ELVERSON  SHAREHOLDER WILL BE PROVIDED WITH
MATERIALS  FOR  EXCHANGING  SHARES  OF  ELVERSON  COMMON  STOCK AS  PROMPTLY  AS
PRACTICABLE AFTER THE EFFECTIVE DATE.

                                   THE MERGER

         The following is a description of the Merger.  Such  description is not
intended to be a complete  description of all facts  regarding the Merger and is
qualified  in all respects by  reference  to the Merger  Agreement  incorporated
herein by reference and attached hereto as Annex A. Shareholders of Elverson and
NPB are urged to read  carefully  the  Merger  Agreement.  For a summary  of the
Merger, see "Summary--The Merger."

         All  ratios  and  share  data  relating  to NPB  and  all  share  price
information relating to the Merger Agreement have been adjusted to reflect NPB's
5-for-4 stock split effected on July 31, 1998 (the "NPB Stock Split").

Background of the Merger

         While in recent years Elverson has competed successfully in its markets
as an independent  community bank,  meeting the increased  efforts by both local
and regional  competitors  to provide new services and attract  customers in its
markets  has become  more and more  difficult.  Given this  heightened  level of
competition,  the Elverson Board has considered  from time to time various forms
of association with other banking  organizations  which would allow Elverson (i)
to capitalize on economies of scale and obtain alternative forms of funding, and
(ii) to provide more innovative  services to its customers,  thus competing more
effectively with larger local and regional banking institutions, consistent with
the Elverson Board's strategic  objectives of remaining a dynamic community bank
serving local markets.

         In May 1997, Lawrence T. Jilk, Jr., Chairman of NPB, contacted Glenn E.
Moyer, President of Elverson and an Elverson Board member, about the feasibility
of pursuing a strategic  combination  between the two institutions.  However, no
specific  price was  discussed  and the  parties  did not  pursue the matter any
further.  In March  and  April of 1998,  Wayne  R.  Weidner,  President  of NPB,
contacted Boyd C. Davis, Jr., a director of Elverson,  indicating that NPB would
be interested in pursuing a merger with Elverson and indicating  informally that
NPB would consider a price based on current market prices of approximately  3.75
times Elverson's book value. In mid-April 1998, Mr. Davis conveyed this interest
to the other members of the Elverson Board.  The Elverson Board retained Dechert
Price &  Rhoads  as  special  counsel  in  April  and  Berwind  Financial,  L.P.
("Berwind")  as its financial  advisor in May to assist it in evaluating the NPB
proposal.

         On May 8, 1998,  Joseph A. Rigg,  Chairman of the Elverson  Board,  Mr.
Davis, Mr. Moyer, and John A. Koury, Jr., an Elverson Board member, met with Mr.
Jilk and Mr. Weidner,  who gave Elverson certain public  information  concerning
NPB and confirmed  NPB's previous  proposal.  Thereafter,  from time to time the
Elverson Board  continued to meet to review the proposal and the  possibility of
merging with NPB. On May 29, Berwind  delivered a preliminary  evaluation of the
NPB proposal to the Board and on June 11, the Elverson Board as a whole met with
Mr. Jilk and Mr. Weidner to discuss strategic issues.

         After  further  Board  meetings,  the Elverson  Board  decided that the
proposal  merited  continued  discussion  and as of June 15, the parties  signed
mutual  confidentiality  letters and began a series of meetings  concerning  due
diligence and the terms of the offer.

         On June 24,  at the  Elverson  Board's  request,  NPB sent a letter  to
Elverson  setting  forth a  non-binding  indication  of  interest  in  acquiring
Elverson.  The  proposal  provided  that NPB would issue  1.46875  shares of NPB
Common  Stock in exchange  for each share of  Elverson  Common  Stock,  and give
Elverson the right to terminate the  acquisition  if (i) the market price of NPB
Common  Stock were to decline to less than $23 per share as of a to be specified
date  shortly  before the Closing and (ii) that  decline  were also five percent
more than the decline in an index (the "Bank  Index") of stock prices of a group
of comparable Pennsylvania bank holding companies over the same time period. NPB
could,  however,  override such termination by increasing the proposed  exchange
ratio by multiplying  that ratio by a fraction,  the numerator of which would be
$23 and the  denominator of which would be the price per share of the NPB Common
Stock as of the  specified  date.  NPB also  offered (i) to issue stock  options
exercisable  for shares of NPB Common Stock in exchange  for the Elverson  stock
options  outstanding for shares of NPB Common Stock in exchange for the Elverson
stock  options  outstanding  on the  date of the  Closing,  (ii) to  incorporate
Elverson into NP Bank by forming a new banking division,  Elverson National Bank
(the  "Elverson  Division"),  and  (iii) to  offer  employment  to each  current
Elverson  employee.  In  addition,  NPB  offered  to add  two  current  Elverson
Directors  to the 

                                       26
<PAGE>
NPB Board and to the NP Bank  Board and create the  Elverson  Division  Board of
Directors,  which would  include the current  members of the Elverson  Board and
which would focus on the division's sales, marketing and expansion.

         The Elverson Board  thereafter  considered  this proposal and continued
discussions with NPB's management. On June 30, NPB delivered a revised letter of
interest  proposing  to adjust  the  exchange  ratio to 1.5 shares of NPB Common
Stock if the market price of NPB Common Stock declined more than 10% and to give
Elverson the right to terminate the merger agreement if such price declined more
than 20% and that  decline were also 5% more than the decline in the Bank Index.
NPB could,  however,  override that termination by increasing the exchange ratio
to 1.5625.  Elverson also was provided a right to terminate the merger agreement
if the market price of NPB Common Stock  declined  more than 25%.  Over the next
few days the  Elverson  Board  continued  to  consider  the  offer and on July 2
decided, without taking formal action, to begin in depth negotiations with NPB.

         Negotiations continued over the next several weeks,  concerning,  among
other items,  integration  and employment  issues,  pricing  structure,  closing
conditions and termination  provisions.  During this period of time the Elverson
Board met from time to time to review the status of discussions. At a meeting on
July 21, the Elverson  Board  reviewed with its outside  legal,  accounting  and
financial  advisors the results of such advisors' due  diligence,  the financial
terms  of  the  proposed  transaction  and  the  terms  of the  proposed  merger
agreement, and Berwind gave its opinion as to the fairness of the exchange ratio
to the  Elverson  shareholders.  Mr.  Moyer  presented  the  results of Elverson
management's  due  diligence  and  discussed  Elverson's  strategic  objectives,
comparing  Elverson's  potential as an  independent  entity and as a division of
NPB. Mr. Moyer noted the  opportunity  which the Merger presents for Elverson to
pursue its goals with a partner which both shares  Elverson's  corporate culture
and  philosophy  and has the  resources  and products  which  Elverson  needs to
achieve its goals After additional  discussion of the Merger, the Elverson Board
unanimously approved the proposed merger agreement.  After that meeting, NPB and
Elverson  executed the proposed  merger  agreement  and the directors of NPB and
Elverson executed agreements providing that they would vote the shares of NPB or
Elverson common stock for which they have sole voting power, as the case may be,
in favor of the Merger.  The transaction  was publicly  announced early the next
morning. In September 1998, Elverson,  NPB and NP Bank amended the agreement and
plan of merger to make certain technical changes involving employee benefits.

Reasons for the Merger; Recommendations of the Boards of Directors

         Elverson's Reasons for the Merger

     In deciding to approve the Merger  Agreement and the related  transactions,
the Elverson Board consulted with its legal,  accounting and financial advisors,
and considered various factors, including the following:

     (i)   The  Elverson  Board's  review of  Elverson's  business,  operations,
           financial   condition  and  earnings,   on  both  a  historical   and
           prospective basis;

     (ii)  the  Elverson  Board's  assessment  of the  current  and  prospective
           economic and competitive  environment  facing the financial  industry
           generally  and  Elverson  in  particular,  including  the  industry's
           continuing rapid consolidation,  the increasingly  important benefits
           of operational scale, and the benefits of product diversification and
           the  strategic  alternatives  currently  available  to  Elverson  for
           increasing  shareholder  value  and  the  timing  and  likelihood  of
           actually achieving such increases;

     (iii) the increased  opportunities  for growth and  operating  efficiencies
           (especially  the  integration  of operations  and support  functions)
           which could result from the Merger;

     (iv)  the  Elverson  Board's  knowledge  and  review,   based  in  part  on
           presentations   by  its   financial  and   accounting   advisors  and
           management,  of the  business,  operations,  financial  condition and
           earnings of NPB and its long term strategies and direction, including
           its  strategic  compatibility  with  Elverson and the  commitment  to
           community banking which the two banks share;

     (v)   the role that the  Elverson  Division  would play  within NPB and the
           general  impact  which the Merger is expected  to have on  Elverson's
           various  constituencies,   including  its  customers,  employees  and
           communities,  including NPB's  commitment to offer employment to each
           of  Elverson's  employees,  

                                       27
<PAGE>

           provide employee  benefits to Elverson  employees,  and NPB's plan to
           expand services in the areas  currently  served by Elverson (see "The
           Merger--Employee Benefits and Severance");

     (vi)  the  expectation  that the Merger will be tax free for federal income
           tax purposes to Elverson and its  shareholders  and will qualify as a
           pooling of interests for accounting and financial  reporting purposes
           (see "The  Merger--Certain  Federal Income Tax Consequences" and "The
           Merger--Accounting Treatment");

     (vii) the  opinion of Berwind  (including  the  assumptions  and  financial
           information and projections relied upon by Berwind in arriving at its
           opinion) that, as of July 21, 1998, the financial terms of the Merger
           were fair to the Elverson shareholders from a financial point of view
           (see  "The   Merger--Opinions  of  Financial   Advisors--Opinion   of
           Elverson's Financial Advisor");

     (viii)the terms of the Exchange  Ratio,  which may result in a  fluctuating
           value  per  share  of  Elverson  Common  Stock  based  on the  market
           performance  of NPB Common  Stock  prior to the  consummation  of the
           Merger,  counterbalanced to a limited extent by the upward adjustment
           of the Exchange Ratio and Elverson's  ability to terminate the Merger
           Agreement in certain circumstances based on the market performance of
           NPB Common  Stock (see "The  Merger--Terms  of the  Merger"  and "The
           Merger--Termination; Possible Exchange Ratio Increase"); and

     (ix)  certain other nonfinancial  terms of the Merger Agreement,  including
           NPB's  commitment to add two members of the Elverson Board to the NPB
           and NP Bank Boards and to create the Elverson Division Board.

         There can be no assurance that any of the potential savings,  synergies
or  opportunities  considered by the Elverson Board will be achieved through the
Merger. See "Cautionary  Statement  Concerning  Forward-Looking  Statements." In
view of the wide variety of material factors which the Elverson Board considered
in its evaluation of the Merger,  the Elverson Board did not find it practicable
to, and did not,  quantify or otherwise attempt to assign any relative weight to
the various  factors it considered.  In addition,  different  directors may have
given varying weight to certain factors.

     THE BOARD OF DIRECTORS OF ELVERSON HAS UNANIMOUSLY  APPROVED THE MERGER AND
THE  MERGER  AGREEMENT  AND  BELIEVES  THAT THE  PROPOSED  MERGER IS IN THE BEST
INTEREST  OF  ELVERSON  AND ITS  SHAREHOLDERS  AND  RECOMMENDS  THAT  ELVERSON'S
SHAREHOLDERS VOTE TO APPROVE THE MERGER AND THE MERGER AGREEMENT.

         NPB's Reasons for the Merger

         NPB's   acquisition   strategy   consists  of   identifying   financial
institutions with business  philosophies that are similar to those of NPB, which
operate in strong  markets  that are  geographically  compatible  with NPB,  are
financially  sound and can be acquired at an acceptable  cost.  Acquisitions are
also  evaluated  in  terms of  asset  quality,  interest  rate  risk,  potential
operating efficiencies and management capabilities.

         In determining the terms of its offer for Elverson and whether to enter
into the Merger  Agreement,  NPB's  Board of  Directors  considered  a number of
factors, including the following: (i) the financial condition, operating results
and future  prospects of NPB and Elverson,  (ii)  historical pro forma financial
information on the Merger,  including,  among other things, pro forma book value
and earnings per share  information,  dilution analysis and capital ratio impact
information,  (iii) a comparison  of the price being paid in the Merger to other
comparable  financial  institution  mergers,   based  on,  among  other  things,
multiples of book value and earnings, (iv) the historical trading prices for the
Elverson  Common  Stock and the NPB  Common  Stock,  (v) a review of  comparable
transactions and management's view, based on such comparable transactions,  that
NPB would be able to obtain an opinion from a reputable  investment banking firm
as to the fairness of the Exchange  Ratio to NPB from a financial  point of view
(which  opinion was  subsequently  delivered  to the NPB Board by LSC  Financial
Services,  Inc., as described under "The Merger--Opinions of Financial Advisors"
below),  and (vi) the  geographic  location of  Elverson's  franchise,  which is
complementary  to NPB's  existing  franchise in Chester  County,  southern Berks
County and eastern Lancaster County, Pennsylvania.

                                       28
<PAGE>
         In  approving  the  transaction,  the NPB  Board  did not  specifically
identify any one factor or group of factors as being more  significant  than any
other factor in the decision making process,  although individual  directors may
have given one or more factors more weight than other  factors.  The emphasis of
the NPB Board's discussion in considering the transaction,  however,  was on the
financial  aspects of the  transaction,  particularly  (i) the strategic fit and
enhanced  franchise  value  discussed  above,  including  pro forma market share
information relating to deposits in Chester County, Pennsylvania, (ii) perceived
opportunities  to increase the combined  company's  commercial  lending,  and to
reduce the combined company's  operating expenses,  following the Merger,  (iii)
the  ability to  increase  NPB's  capital  base,  thereby  increasing  operating
flexibility,  (iv) Elverson's asset quality,  (v) the absence of any significant
earnings per share dilution and significant  potential for accretion in light of
potential revenue  enhancements and cost savings resulting from the Merger, (vi)
the  significant  increase in capital  resulting from the Merger,  and (vii) the
pricing   provisions  of  the  Merger  Agreement,   which  provide  for  certain
adjustments  and  termination  rights  under  certain  circumstances.  See  "The
Merger--Terms of the Merger."

         Recommendation of the Elverson Board of Directors

         The  Board of  Directors  of  Elverson  believes  that the terms of the
Merger are fair to, and in the best interests of, Elverson and its  shareholders
and has  unanimously  approved the Merger  Agreement.  The Board of Directors of
Elverson  unanimously  recommends that the  shareholders of Elverson approve the
Merger Agreement.

         Recommendation of the NPB Board of Directors

         The Board of Directors of NPB believes that the terms of the Merger are
fair  to,  and in the  best  interests  of,  NPB  and its  shareholders  and has
unanimously  approved  the  Merger  Agreement.  The  Board of  Directors  of NPB
unanimously   recommends  that  the  shareholders  of  NPB  approve  the  Merger
Agreement.

Terms of the Merger

         Upon completion of the Merger, the separate legal existence of Elverson
will  cease.  All  property,  rights,  powers,  duties,  obligations,  debts and
liabilities of Elverson will automatically be taken and deemed to be transferred
to and vested in NP Bank, as the surviving  bank  (sometimes  referred to as the
"Surviving  Bank").  The  Surviving  Bank will be  governed  by the  articles of
association and bylaws of NP Bank in effect  immediately  prior to completion of
the Merger.

         On the Effective Date of the Merger, each outstanding share of Elverson
Common Stock (other than any dissenting shares) will be automatically  converted
into,  and become a right to receive,  1.46875  shares of NPB Common  Stock (the
"Exchange  Ratio"),  provided  that the NPB Market  Value (as defined  below) is
greater  than or equal to $24.30.  If the NPB Market  Value is less than $24.30,
the Exchange  Ratio will be adjusted in certain  circumstances  and the Exchange
Ratio may be adjusted at NPB's discretion in other  circumstances,  as described
in the following paragraphs:

         If the NPB  Market  Value is less than  $24.30  but  either (i) the NPB
Market  Value is greater  than or equal to $21.60 or (ii) the NPB  Market  Value
Quotient (as hereinafter  defined) is not less than the Index Group Standard (as
hereinafter  defined) by 5% or more, each  outstanding  share of Elverson Common
Stock (other than any  dissenting  shares) will be converted  into, and become a
right to receive, 1.5 shares of NPB Common Stock.

         If (i) the NPB Market  Value is less than  $21.60,  (ii) the NPB Market
Value  Quotient is less than the Index Group  Standard by 5% or more,  and (iii)
Elverson  has  properly  elected to  terminate  the Merger  Agreement  (see "The
Merger--Termination;  Possible  Exchange  Ratio  Increase"),  NPB will  have the
option to increase the Exchange Ratio and thereby nullify  Elverson's  election.
In that event, each outstanding share of Elverson Common Stock will be converted
into, and become a right to receive, 1.5625 shares of NPB Common Stock.

         The number of shares of NPB  Common  Stock  issuable  in  exchange  for
outstanding  shares of Elverson Common Stock will be further adjusted to prevent
dilution in the event of  additional  stock splits,  reclassifications  or other
similar events.

                                       29
<PAGE>

          NPB will in all events pay cash to  Elverson  shareholders  in lieu of
issuing  fractional  shares of NPB Common Stock.  Each share of Elverson  Common
Stock issued and held as treasury  shares by Elverson as of the Effective  Date,
if any,  will be  canceled,  and NPB will not deliver  any cash,  stock or other
property in exchange for such shares.

         As of the Elverson  Record  Date,  certain  employees of Elverson  held
options to purchase an aggregate of 43,890 shares of Elverson Common Stock which
had been  granted  pursuant to  Elverson's  stock  option  plans (the  "Elverson
Options"). On the Effective Date, each Elverson Option which is then outstanding
shall cease to represent a right to acquire shares of Elverson  Common Stock and
shall be converted automatically into an option to purchase shares of NPB Common
Stock, and NPB shall assume each Elverson  Option,  in accordance with the terms
of the applicable Elverson stock option plan and stock option agreement by which
it is evidenced,  except that from and after the Effective Date, (i) NPB and its
Board of Directors or a duly authorized  committee  thereof shall be substituted
for Elverson and  Elverson's  Board of  Directors or duly  authorized  committee
thereof administering such Elverson stock option plan, (ii) each Elverson Option
assumed by NPB may be exercised solely for shares of NPB Common Stock, (iii) the
number of shares of NPB Common Stock  subject to such  Elverson  Option shall be
equal to the number of shares of Elverson  Common Stock subject to such Elverson
Option  immediately prior to the Effective Date multiplied by the Exchange Ratio
(as it may be adjusted),  and (iv) the per share  exercise price under each such
Elverson Option shall be adjusted by dividing the per share exercise price under
each such Elverson Option by the Exchange Ratio (as it may be adjusted).

         The NPB Common Stock and cash to be received by the holders of Elverson
Common Stock (including the holders of options to acquire Elverson Common Stock)
in exchange for each share (other than any dissenting shares or treasury shares)
of Elverson Common Stock  (including  shares subject to options) are referred to
herein as the "Merger Consideration."

Opinions Of Financial Advisors

         Opinion of Elverson's Financial Advisor

         Elverson retained Berwind to act as its financial advisor and to render
a fairness  opinion in connection with the Merger.  Berwind rendered its opinion
to the Board of  Directors  of  Elverson  that,  based  upon and  subject to the
various  considerations  set forth  therein,  as of,  July 21,  1998 (the  "July
Opinion"),  and as of __________,  1998 (the "Proxy Opinion"), the consideration
to be received in the Merger is fair,  from a  financial  point of view,  to the
holders of Elverson Common Stock.

         The  full  text of  Berwind's  Proxy  Opinion,  which  sets  forth  the
assumptions made,  matters  considered and limitations of the review undertaken,
is  attached  as Annex B to this  Proxy  Statement/Prospectus,  is  incorporated
herein by reference,  and should be read in its entirety in connection with this
Proxy  Statement/Prospectus.  The  summary of the  opinion of Berwind  set forth
herein  is  qualified  in its  entirety  by  reference  to the full text of such
opinion attached as Annex B to this Proxy Statement/Prospectus.

         Berwind  was  selected  to  act  as  Elverson's  financial  advisor  in
connection  with  the  Merger  based  upon  its  qualifications,  expertise  and
experience.  Berwind has knowledge of, and  experience  with,  Pennsylvania  and
surrounding banking markets, as well as banking organizations operating in those
markets,  and was selected by Elverson  because of its knowledge of,  experience
with, and reputation in the financial  services industry.  In addition,  Berwind
was engaged by Elverson in 1994 in connection with providing  general  financial
advisory  services.  Berwind,  as part of its investment  banking  business,  is
engaged  regularly  in the  valuation  of assets,  securities  and  companies in
connection  with various types of asset and securities  transactions,  including
mergers,  acquisitions,  private  placements,  and  valuations for various other
purposes  and  in  the   determination   of  adequate   consideration   in  such
transactions.

         On July 21, 1998,  Elverson's Board of Directors  approved and executed
the proposed merger  agreement.  Prior to such approval,  Berwind  delivered its
July  Opinion  to  Elverson's   Board  stating  that,  as  of  such  date,   the
consideration  to be  received  in the  Merger was fair to the  shareholders  of
Elverson from a financial point of view.  Berwind reached the same opinion as of
the date of its Proxy  Opinion.  The full text of the Proxy  Opinion  which sets
forth assumptions made,  matters  considered and limits on the review undertaken
is attached as Annex B to this Proxy  Statement/Prospectus.  No limitations were
imposed by  Elverson's  Board of  Directors  upon  Berwind  with  respect to the
investigations  made or  procedures  followed by Berwind in  rendering  the July
Opinion or the Proxy Opinion.

         In rendering  its Proxy  Opinion,  Berwind (i) reviewed the  historical
financial  performances,  current  financial  positions and general prospects of
Elverson and NPB; (ii) reviewed the  Agreement;  (iii) reviewed and analyzed the
stock  market  performance  of Elverson  and NPB;  (iv) studied and analyzed the
consolidated  financial and operating  data of Elverson and NPB; (v)  considered
the terms and  conditions of the proposed  Merger as compared with the terms and
conditions of comparable bank and bank holding company mergers and acquisitions;
(vi) met and/or communicated with certain members of Elverson's and NPB's senior
management  to  discuss  their  respective   operations,   historical  financial
statements,   and  future   prospects;   (vii)   reviewed   this   joint   Proxy
Statement/Prospectus,  and  (viii)  conducted  such  other  financial  analyses,
studies and investigations as Berwind deemed appropriate.

         In delivering its July Opinion and Proxy Opinion,  Berwind assumed that
in the course of obtaining the necessary  regulatory and governmental  approvals
for the Merger,  no  restriction  will be imposed on NPB or Elverson  that would
have a material  adverse  effect on the  contemplated  benefits  of the  Merger.
Berwind also assumed that there will not occur any change in  applicable  law or
regulation  that  would  cause a material  adverse  change in the  prospects  or
operations of NPB after the Merger.

         Berwind 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  opinions.  With  respect to  Elverson's
financial  forecasts  reviewed by Berwind in  rendering  its  opinions,  Berwind
assumed  that  such  financial  forecasts  were  reasonably  prepared  on  bases
reflecting  the  best  currently   available  estimates  and  judgments  of  the
management  of  Elverson as to the future  financial  performance  of  Elverson.
Berwind  did not make an  independent  evaluation  or  appraisal  of the  assets
(including  loans) or  liabilities  of Elverson or NPB nor was it furnished with
any such appraisal.  Berwind also did not independently verify and has relied on
and  assumed  that all  allowances  for loan and lease  losses  

                                       31
<PAGE>
set forth in the balance  sheets of Elverson and NPB were  adequate and complied
fully with applicable law,  regulatory  policy and sound banking  practice as of
the date of such financial statements.

         The following is a summary of selected analyses prepared by Berwind and
presented to Elverson's  Board in connection  with the July Opinion and analyzed
by Berwind in connection  with the July and Proxy  Opinions.  In connection with
delivering its Proxy Opinion,  Berwind updated certain analyses  described above
to reflect current market  conditions and events occurring since the date of the
July  Opinion.  Such reviews and updates led Berwind to conclude that it was not
necessary to change the  conclusions it had reached in connection with rendering
the July Opinion.

         Comparable Companies and Comparable  Acquisition  Transaction Analyses.
Berwind  compared  selected  financial,  operating,  and stock  market  data for
Elverson with those of a peer group of selected banks and bank holding companies
with  assets  between  $200  million  and $600  million,  as of the most  recent
financial period publicly available,  headquartered in Berks, Chester, Delaware,
Lancaster,  and Montgomery  counties in Pennsylvania.  Financial,  operating and
stock market data, ratios and multiples compared in the analysis of the Elverson
peer group included but were not limited to: return on average assets, return on
average  shareholders'  equity,  shareholders'  equity to assets ratio,  certain
asset quality ratios,  price to book value,  price to tangible book value, price
to earnings  (latest  twelve  months) and dividend  yield.  The analysis  showed
Elverson's  return on average assets was 1.08% compared to the peer group median
of 1.62%, its return on average  shareholders' equity was 11.56% compared to the
peer group median of 13.16%, its shareholders'  equity as a percentage of assets
was 9.3% versus the peer group median of 11.1%,  its  non-performing  assets and
loans  past  due 90 days or more as a  percentage  of  total  assets  was  0.89%
compared  to the peer  group  median of 0.83%,  and its loan loss  reserve  as a
percentage  of  non-performing  assets  and  loans  past due 90 days or more was
166.75% versus the median of 165.73% for the peer group.

         In addition, the analysis showed that Elverson's common stock price per
share ($25.75 on the date of the July Opinion) as a percentage of book value and
tangible book value per share was 251.0% and 251.0%,  respectively,  compared to
the peer group medians of 266.9% and 266.9%, respectively,  and its common stock
price per share as a multiple of latest  twelve  months'  earnings  per share of
22.2 times compared to the peer group median of 20.3 times.

         Berwind also compared  selected  financial,  operating and stock market
data for NPB with  those of a peer  group of  selected  banks  and bank  holding
companies  with assets  between  $1.0 billion and $3.0  billion,  as of the most
recent period publicly available,  headquartered in New Jersey, Pennsylvania and
Maryland.  Financial,  operating  and stock  market data,  ratios and  multiples
compared in the analysis of the NPB peer group included but were not limited to:
return on average assets, return on average shareholders' equity,  shareholders'
equity to asset ratios, certain asset quality ratios, price to book value, price
to tangible book value,  price to earnings  (latest  twelve months and estimated
1998) and dividend yield. The analysis showed NPB's return on average assets was
1.29%  compared  to the peer  group  median of  1.10%,  its  return  on  average
shareholders' equity was 16.26% compared to the peer group median of 13.29%, its
shareholders'  equity as a percentage  of assets was 8.03% versus the peer group
median of 8.47%, its non-performing assets and loans past due 90 days or more as
a  percentage  of total  assets was 0.71%  compared to the peer group  median of
0.63%,  and its loan loss reserve as a percentage of  non-performing  assets and
loans past due 90 days or more was 231.79%  versus the median of 164.27% for the
peer group.

         In  addition,  the  analysis  showed that NPB's  common stock price per
share ($26.70 on the date of the July Opinion) as a percentage of book value and
tangible book value per share was 291.0% and 308.2%,  respectively,  compared to
the peer group medians of 252.9% and 278.3%, respectively,  and its common stock
price per share as a multiple of latest  twelve  months'  earnings  per share of
17.8 times compared to the peer group median of 19.4 times.

         Berwind also compared the multiples of book value,  tangible book value
and latest  twelve  months'  earnings  inherent to the Merger with the multiples
paid in recent  acquisitions  of banks and bank holding  companies  that Berwind
deemed comparable.  The transactions  deemed comparable by Berwind included both
interstate  and  intrastate  acquisitions  announced  during the  twelve  months
preceding  the date of the proxy  opinion,  in which the  selling  institution's
assets were between  $200 million and $600 million as of the most recent  period
publicly available prior to announcement.  Berwind compared transactions located
throughout  the country and  analyzed  those  transactions  in three  groups:  a
national group (62 banks), a regional group (6 banks),  and a performance  group
(30  banks).  The  national  group  included   commercial  banking   institution
transactions   throughout  the  United  States;   the  regional  group  included
transactions involving commercial banking institutions located in New Jersey and
Pennsylvania;   and  the  performance  

                                       32
<PAGE>

group included  transactions  involving  commercial  banking  institutions  with
return  on  average  shareholders'  equity  less  than or  equal  to  14.0%  and
shareholders'  equity as a percentage  of total assets  greater than or equal to
6.5%. The median values  calculated for price as a percentage of book value were
263.7%,  281.1%, and 247.6% for the national,  regional,  and performance group,
respectively;  the median of price as a  percentage  of tangible  book value was
275.3%,  281.1% and 260.7% for the national,  regional,  and performance  group,
respectively;  and the median of price as a multiple  of latest  twelve  months'
earnings per share was 21.3,  31.0,  and 21.8 times for the national,  regional,
and performance group,  respectively.  These medians compare to the Merger price
per share as a  percentage  of book value,  price per share as a  percentage  of
tangible  book  value and price per share as a  multiple  of the  latest  twelve
months' earnings of 371.7%, 371.7% and 31.6 times, respectively.

         No company or transaction,  however, used in this analysis is identical
to Elverson,  NPB or the Merger.  Accordingly,  an analysis of the result of the
foregoing is not mathematical;  rather, it involves complex  considerations  and
judgments concerning  differences in financial and operating  characteristics of
the companies and other factors that would affect the public  trading  values of
the companies or company to which they are being compared.

         Discounted  Dividend  Analyses.  Using  discounted  dividend  analyses,
Berwind estimated the present value of Elverson's Common Stock after a five year
period by applying a range of earnings  multiples to  Elverson's  terminal  year
earnings under various growth assumptions. The range of multiples used reflected
a variety of  scenarios  regarding  the growth and  profitability  prospects  of
Elverson.  The  terminal  values  were then  discounted  to present  value using
discount rates,  reflecting different  assumptions regarding the rates of return
required  by holders or  prospective  buyers of  Elverson's  Common  Stock.  The
discounted dividend analysis indicated a range of values of $16.19 to $24.72 per
share.

         Pro Forma  Contribution  Analysis.  Berwind analyzed the changes in the
amount  of  earnings,  book  value  and  dividends  represented  by one share of
Elverson  stock  prior to the Merger and the number of shares of NPB stock after
the Merger  resulting from the Exchange Ratio.  The analysis  considered,  among
other things, the changes that the Merger would cause to Elverson's earnings per
share, book value per share and indicated  dividends.  On a per share equivalent
basis,  Elverson's  earnings per share would be $2.08,  its book value per share
would be $13.04 and its indicated  dividend per share would be $1.12 compared to
an  actual  earnings  per  share of $1.34,  book  value per share of $10.55  and
indicated  dividend  per share of $0.24.  In  reviewing  the pro forma  combined
earnings,  equity and assets of NPB based on the Merger with  Elverson,  Berwind
analyzed  the  contribution  that  Elverson  would  have  made  to the  combined
company's  earnings,  equity and assets as of and for the most recent  quarterly
period  ended as of the date of the Proxy  Opinion.  Berwind  also  reviewed the
percentage  ownership  that  Elverson  shareholders  would hold in the  combined
company.

         In  connection  with  rendering  its July  Opinion  and Proxy  Opinion,
Berwind  performed a variety of financial  analyses.  Although the evaluation of
the fairness, from a financial point of view, of the consideration to be paid in
the Merger  was to some  extent a  subjective  one based on the  experience  and
judgment  of  Berwind  and not merely the  result of  mathematical  analysis  of
financial data, Berwind principally relied on the previously discussed financial
valuation  methodologies  in its  determinations.  Berwind believes its analyses
must be considered as a whole and that  selecting  portions of such analyses and
factors considered by Berwind without  considering all such analyses and factors
could create an incomplete view of the process underlying Berwind's opinions. In
its  analysis,  Berwind  made  numerous  assumptions  with  respect to business,
market,  monetary  and  economic  conditions,  industry  performance  and  other
matters,  many of which are beyond  Elverson's and National Penn's control.  Any
estimates  contained in Berwind's  analyses are not  necessarily  indicative  of
future results or values, which may be significantly more or less favorable than
such estimates.

         In reaching its opinion as to fairness,  none of the analyses performed
by Berwind was assigned a greater or lesser  weighting by Berwind than any other
analysis.  As a result of its  consideration  of the  aggregate  of all  factors
present and analyses performed, Berwind reached the conclusion, and opined, that
the consideration to be received in the Merger as set forth in the Agreement, is
fair from a financial point of view to Elverson and its shareholders.

         Berwind's Proxy Opinion was based solely upon the information available
to it and the economic, market and other circumstances as they existed as of the
date its Proxy Opinion was  delivered;  events  occurring  after the date of its
Proxy  Opinion could  materially  affect the  assumptions  used in preparing its
Proxy  Opinion.  Berwind has not  

                                       33
<PAGE>

undertaken  to reaffirm and revise its Proxy  Opinion or otherwise  comment upon
any events occurring after the date thereof.

         Pursuant  to the terms of the  engagement  letter  dated May 14,  1998,
Elverson has paid Berwind $35,000 for serving as financial advisor. Elverson has
also  agreed to pay  Berwind  $175,000,  plus  three  percent  of the  aggregate
positive  difference,  if any, between the final transaction value of the Merger
to the ENB  shareholders and  $103,557,491,  upon the consummation of the Merger
for  acting  as  financial  advisor  in  connection  with the  Merger  including
delivering  its  July  and  Proxy  Opinions.   Whether  or  not  the  Merger  is
consummated,  Elverson has also agreed to indemnify  Berwind and certain related
persons  against  certain  liabilities   relating  to  or  arising  out  of  its
engagement and to reimburse Berwind for certain out of pocket expenses.

         The full text of the Proxy  Opinion of Berwind  dated as of the date of
this Proxy  Statement/Prospectus,  which sets forth assumptions made and matters
considered,  is attached hereto as Annex B. Elverson's shareholders are urged to
read the Proxy Opinion in its entirety. Berwind's Proxy Opinion is directed only
to the financial  consideration to be received by Elverson's shareholders in the
Merger and does not constitute a recommendation to any holder of Elverson Common
Stock as to how such holder should vote at the Elverson Meeting.

         THE  FOREGOING  PROVIDES ONLY A SUMMARY OF THE PROXY OPINION OF BERWIND
AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THAT  OPINION,
WHICH IS SET FORTH IN ANNEX B TO THIS PROXY STATEMENT/PROSPECTUS.

         Opinion of NPB's Financial Advisor

         As   described   in  more  detail   under   "Reasons  for  the  Merger;
Recommendations  of the  Boards of  Directors",  the Board of  Directors  of NPB
approved the Merger  Agreement  subject to receipt of a written opinion that the
terms of the Merger were fair,  from a financial  point of view,  to NPB and its
shareholders.  On July 21, 1998, LSC Financial Services,  Inc. ("LSC") delivered
to NPB its  definitive  written  opinion to that effect,  which  opinion LSC has
updated to the date hereof. The full text of LSC's opinion, which sets forth the
assumptions made, matters considered and limitations on the review undertaken in
connection with such opinion,  is set forth in Annex C hereto and should be read
in its entirety.

         LSC is a  nationally  recognized,  regional  investment  banking  firm,
regularly engaged in the valuation of banks and other financial institutions and
their securities.

         LSC was retained by NPB on June, 16, 1998, to render an opinion, from a
financial  point of view, as to the fairness of the terms of the proposed merger
with Elverson  National Bank to NPB and its  shareholders.  See "Reasons for the
Merger;  Recommendations  of the Boards of Directors."  NPB's Board of Directors
selected  LSC  on  the  basis  of  its  experience  in  valuation  of  financial
institutions and their securities,  its representation of NPB in previous merger
transactions,  its familiarity  with the commercial  banking industry and merger
and  acquisition  transactions  in the  region,  and on the  basis of  cost.  No
limitations were imposed by NPB or Elverson with respect to the opinion rendered
by LSC or the scope of its investigation.

         The terms of the Merger were not  determined  by LSC,  but instead were
established by the Boards of Directors of NPB and Elverson.

         LSC arrived at its opinion after  discussions  with senior  officers of
NPB and Elverson, a review of pertinent financial information concerning NPB and
Elverson,  a review of the trading  history of NPB and Elverson  common stock, a
review of the dividend record of NPB and Elverson, a comparison of the financial
terms of the  Merger  with  the  terms of  other  recent  business  combinations
involving banks and bank holding  companies,  review of the Merger Agreement and
the  Proxy   Statement/Prospectus,   and  such  other   analyses,   studies  and
investigations as LSC deemed relevant.  LSC also reviewed with NPB's management,
the results of NPB's due diligence examination of Elverson, the expected revenue
enhancements and cost savings related to the Merger,  and the strategic benefits
expected to be derived from the Merger.

         In accordance with customary investment banking practice,  LSC employed
generally accepted valuation methods in reaching its opinion. The following is a
summary of the material  financial  analyses  utilized by LSC in connection with
providing its opinion.

                                       34
<PAGE>

         Pro Forma  Merger  Analysis.  LSC  analyzed  certain pro forma  effects
resulting  from the Merger based on (i)  projected  earnings of NPB and Elverson
for 1998  prepared by the  respective  managements  of NPB and Elverson and (ii)
expense  savings  of  40%  of  Elverson's  non-interest  expenses  estimated  by
management of NPB to be attainable in the merger.  This analysis  indicated that
the transaction  would be accretive to the  shareholders of NPB from an earnings
per share perspective, during the second year after consummation of the merger.

         Contribution  Analysis.  LSC compared the relative  contribution to the
continuing  NPB  attributable  to each of NPB and  Elverson as of June 30, 1998.
This analyses  showed that NPB and Elverson  would  contribute to the continuing
NPB  approximately  85% and  15%,  respectively,  of total  assets,  86% and 14%
respectively,  of total loans, 81% and 19% of total deposits, and 81% and 19% of
tangible book value.

         In addition,  LSC computed the relative contribution of each of NPB and
Elverson in terms of income  statement  items,  including  net interest  income,
non-interest  income,  non-interest  expense and net income based on  annualized
June  30,  1998  results.  This  analysis  showed  that NPB and  Elverson  would
contribute  86% and 14%,  respectively,  of net income for 1998.  LSC also noted
that on a pro  forma  basis  the  current  shareholders  of NPB  and the  former
shareholders of Elverson would own 77% and 23%, respectively,  of the continuing
NPB.

         Discounted Dividend Stream Analysis. Using a discounted dividend stream
analysis,  LSC estimated  the present  value of the future  streams of after tax
cash flows that  Elverson  could  produce  through  earnings and  distribute  to
shareholders  after  consummation of the Merger.  In this analysis,  LSC assumed
that NPB could pay out up to 100% of its  adjusted  net  income  subject  to the
assumed constraint that Elverson's common equity to asset ratio be maintained at
a level of not less than 7%. LSC added to this  stream of  after-tax  cash flows
assumed expense savings equal to 40% of Elverson's non-interest expenses,  which
were projected to be achieved by NPB's management in connection with the Merger.
The projected  dividend  streams and terminal  values were discounted to present
values using discount rates of 10%, 11% and 12%. This discounted dividend stream
analysis implied a reference range of values for Elverson common stock of $38.61
to $46.19 per share.

         Selected  Transaction   Analysis.   LSC  analyzed  certain  information
compiled  by SNL  Securities  L.P.  (a data firm  that  monitors  and  publishes
transaction  summaries  and  descriptions  of mergers  and  acquisitions  in the
financial   services   industry)  relating  to  Pennsylvania  bank  acquisitions
(excluding   mergers  of  equals)   announced   since  October  1997.  For  such
transactions  LSC  considered a range of multiples  for price as a percentage of
book value from 269.5% to 364.5% with an average of 322%. LSC also  considered a
range of  multiples  of earnings  per share from 20.8 to 32.8 with an average of
27.2 and a median of 27.0. This selected  transaction  analysis  implied a value
range for Elverson  Common Stock of $25.79 to $40.67 per share based on selected
Pennsylvania transactions under $275 million in aggregate value.

         The  description  of LSC's  analyses  set forth  above  summarizes  the
material aspects of the analyses performed but does not purport to be a complete
description  of the analyses  performed by LSC.  The  preparation  of a fairness
opinion  is a complex  process  and is not  necessarily  susceptible  to partial
analysis or summary  description.  LSC believes that the summary set forth above
and its  analyses  must be  considered  as a whole and that  selecting  portions
thereof,  without  considering  all of the analyses,  could create an incomplete
view of the processes underlying its analyses and opinion. LSC based its opinion
on  assumptions  that it deemed  reasonable,  including  assumptions  concerning
general business and economic conditions and  industry-specific  factors.  LSC's
analyses  are not  necessarily  indicative  of actual  values  or actual  future
results that might be  achieved,  which values may be higher or lower than those
indicated.  Moreover, LSC's analyses are not and do not purport to be appraisals
or otherwise  reflective  of the prices at which  businesses  actually  could be
bought or sold.

         In rendering  its opinion,  LSC assumed that in the course of obtaining
the necessary  regulatory  approvals  for the Merger,  no  restrictions  will be
imposed on NPB that would have a  material  adverse  effect on the  contemplated
benefits of the Merger to NPB.  LSC also  assumed that there would not occur any
change in  applicable  law or  regulation  that would  cause a material  adverse
change in the prospects or operations of NPB after the Merger. LSC also assumed,
with  NPB's  consent,  that the  Merger  will be  accounted  for as a pooling of
interests under generally accepted accounting principles.

         LSC did not  independently  verify the information  used in arriving at
its opinion,  but assumed the accuracy and completeness of all such information.
In that regard,  LSC assumed with NPB's  consent that the  financial  

                                       35
<PAGE>

forecasts,  including,  without  limitation,  projected cost savings,  have been
reasonably prepared on a basis reflecting the best currently available judgments
and  estimates of the  managements  of NPB and Elverson and that such  forecasts
will be realized in the amounts and at the times contemplated thereby. Also, LSC
did not make or obtain any independent appraisal of the assets or liabilities of
NPB or Elverson.

         For its services,  including rendering the opinion included herein, LSC
will  receive  a fee of  $30,000.  NPB has  also  agreed  to  reimburse  LSC for
out-of-pocket  expenses  and  to  indemnify  LSC  against  certain  liabilities,
including  liabilities arising under federal securities laws, which may arise in
connection  with the  performance  of its  services  for NPB.  The amount of the
consideration was determined as a result of negotiations between NPB and LSC.

         LSC has had no other material  relationship  with NPB and Elverson,  or
any of their respective  affiliates in the past two years, but from time to time
has  provided  merger  and  acquisition  consulting  services  to NPB and may be
expected to do so in the future.

         LSC'S OPINION IS DIRECTED  ONLY TO THE EXCHANGE  RATIO IN THE MERGER AS
OF THE DATE OF ITS OPINION AND DOES NOT CONSTITUTE A  RECOMMENDATION  TO ANY NPB
SHAREHOLDER  AS TO HOW SUCH  SHAREHOLDER  SHOULD  VOTE AT THE NPB  MEETING.  THE
SUMMARY OF THE  OPINION OF LSC SET FORTH IN THIS PROXY  STATEMENT/PROSPECTUS  IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

         LSC has  filed a  written  consent  relating  to the  inclusion  of its
fairness  opinion  and  the  references  to  such  opinion  and to LSC in  NPB's
Registration  Statement  under the  Securities  Act of 1933 in which  this Proxy
Statement/Prospectus is included. In giving such consent, LSC did not admit that
it comes within the category of persons whose consent is required  under Section
7 of the  Securities  Act or the rules and  regulations  thereunder  nor did LSC
admit  that it is an  expert  with  respect  to any  part  of such  Registration
Statement  within the meaning of the term "expert" as used in the Securities Act
or the rules and regulations thereunder.

         LSC's  opinion was based  solely upon  information  available to it and
provided by NPB and Elverson,  the economic market and other  conditions as they
existed as of the date its opinion was rendered.

Effective Date

         Under the  Merger  Agreement,  the  Effective  Date will be the date on
which all  conditions to the Merger have been  fulfilled or waived or as soon as
practicable  thereafter  as NPB and  Elverson may  mutually  agree.  The parties
presently  expect that the  Effective  Date will occur in early  1999.  See "The
Merger--Conditions to the Merger."

Elverson and NPB; and (s) the tax and accounting treatment of the Merger.

Conduct of Business Pending the Merger

         Pursuant to the Merger  Agreement,  NPB and Elverson each agreed to use
their  reasonable  good faith efforts to preserve their  business  organizations
intact,  to maintain  good  relationships  with  employees  and to preserve  the
goodwill of customers  and others with whom  business  relationships  exist.  In
addition,  Elverson agreed to conduct its business and to engage in transactions
only in the ordinary course of business,  consistent with past practice,  except
as otherwise  required by the Merger  Agreement  or with the written  consent of
NPB, and NPB agreed to conduct its business and to engage in transactions in the
ordinary course without radical change.

         In addition,  Elverson agreed in the Merger Agreement that it will not,
without the written consent of NPB, among other things,  (i) change its articles
of association or bylaws;  (ii) change the number of authorized or issued shares
of its capital  stock,  repurchase  any shares of its capital  stock,  redeem or
otherwise  acquire any shares of its capital stock, or issue or grant options or
similar rights with respect to its capital stock or any  securities  convertible

Elverson Common Stock upon the exercise of Elverson Options  outstanding on July
21, 1998; (iii) declare,  set aside or pay any dividend or other distribution in
respect of its capital stock, except as otherwise  specifically set forth in the
Merger  Agreement  (see "The  Merger--Dividends");  (iv) grant any  severance or

"change-in-control"  or termination  contract or arrangement;  (v) grant any pay
increase,  pay any bonus or grant job  promotions,  except for routine  periodic

in accordance  with past  practice,  retention  bonuses on account of the Merger
granted in good faith  reasonable  amounts,  and pay  increases  and bonuses for
extraordinary  efforts in management and product  development (if such costs are
fully accrued on the Closing  Date);  (vi) engage in any merger,  acquisition or
similar  transaction;  (vii) dispose of or encumber any assets or incur any debt
other than in the ordinary  course of business except for the sale of the excess
property  located at the Blue Rock  Center in the Borough of  Elverson,  Chester
County,  Pennsylvania;  (viii) change any accounting practices, except as may be
required by generally  accepted  accounting  principles  (without  regard to any
optional  early  adoption  date);  (ix)  implement  any new employee  benefit or
welfare plan, or amend any such plan,  unless such  amendment does not result in
an increase in cost, except as expressly permitted by the Merger Agreement;  (x)
purchase any security for its investment  portfolio not rated "AAA" or higher by
either Standard & Poor's or Moody's  Investor  Services,  Inc.; (xi) make, enter
into, renew, extend,  modify or compromise any transaction with any affiliate of
Elverson  other than deposit and loan  transactions  in the  ordinary  course of
business and which are in compliance  with the  requirements  of applicable laws
and regulations; (xii) enter into any interest rate swap floor or cap or similar
arrangement;  (xiii) take any action that would  preclude  the  treatment of the
Merger as a pooling of  interests  for  financial  accounting  purposes  or as a
tax-free  reorganization under the Code; (xiv) waive, release, grant or transfer
any rights of value,  or modify or change in any  material  respect any existing
agreement to which  Elverson is a party,  other than in the  ordinary  course of
business,  consistent with past practice; (xv) take any action which would cause
any of the  representations  and  warranties of Elverson set forth in the Merger
Agreement to be untrue or the conditions set forth in the Merger Agreement to be
unsatisfied;  (xvi) fill job vacancies  that occur prior to the  Effective  Date
through  attrition,  unless  the  integration  team  described  below  deems  it
essential; or (xvii) agree to do any of the foregoing.

         Elverson also agreed in the Merger Agreement,  among other things,  (i)
to permit  NPB, if NPB elects to do so at its own  expense,  to cause a "phase I
environmental  audit" to be performed at any physical  site owned or occupied by
Elverson;  (ii)  if  NPB  acknowledges  that  all  conditions  to  the  parties'
respective  obligations under the Merger Agreement have been waived or satisfied
and that their respective  rights to terminate the Merger Agreement have lapsed,
to establish  additional accruals and reserves to conform Elverson's  accounting
reserve  practices  and  methods to those of NPB and  otherwise  reflect  Merger
expenses of Elverson on a mutually  satisfactory  basis and in  accordance  with
generally accepted accounting principles and applicable regulatory requirements;
and (iii) to  suspend  the  operation  of its  Dividend  Reinvestment  and Stock
Purchase Plan, which was suspended on July 21, 1998.

         NPB and Elverson jointly agreed,  among other things, (i) to submit the
Merger Agreement to their respective shareholders for approval at meetings to be
held as soon as practicable; (ii) to prepare all applications for, 

                                       37
<PAGE>

and use their  reasonable  best  efforts  to  obtain,  all  required  regulatory
approvals;  (iii),  subject  to the terms of the Merger  Agreement,  to take all
actions  necessary  to  complete  the  transactions  contemplated  by the Merger
Agreement;  (iv) to maintain adequate insurance;  (v) to maintain accurate books
and records;  (vi) to file all tax returns and pay all taxes when due; and (vii)
to agree upon the form and substance of any press  release or public  disclosure
related to the Merger Agreement and the Merger.

         NPB and  Elverson  also  agreed in the  Merger  Agreement  to select an
integration  team,  comprising an equal number of senior staff employees of each
of  NPB  and  Elverson,  to  plan  and  implement  an  orderly,   cost-effective
consolidation of Elverson's  operations into NP Bank's  operations in Boyertown,
Pennsylvania. Prior to the Effective Date, consolidation efforts may include, if
mutually  agreed,  (i) the  termination  of any  contract  or  arrangement  that
Elverson  may have with an outside  service  bureau or other vendor of services,
(ii)  the  termination  of any of  Elverson's  in-house  back  office,  support,
processing  or other  operational  activities,  and (iii)  subject to applicable
legal  requirements,  the  substitution of a contract between NPB or NP Bank and
Elverson for the provision of similar services.

         NPB agreed in the Merger  Agreement that, prior to the Closing Date, it
will not, without the written consent of Elverson,  (i) enter into any agreement
with any company  (other  than  Elverson)  concerning  any  acquisition  of such
company by NPB or a merger or  consolidation  of such company with NPB if either
(A) NPB would be required to present pro forma financial  information  regarding
that transaction in the joint proxy  statement/prospectus  for the Merger or (B)
NPB would propose to issue in that transaction  shares of NPB Common Stock in an
amount greater than 20% of the number of shares of NPB Common Stock  outstanding
on July 21, 1998, or (ii) repurchase,  redeem or otherwise acquire any shares of
NPB Common Stock.

Dividends

         The Merger Agreement permits Elverson to pay its regular quarterly cash
dividend of $.06 per share of Elverson  Common Stock  outstanding.  Elverson and
NPB agreed in the Merger  Agreement  to  coordinate  dividend  record  dates and
payment  dates with respect to Elverson  Common Stock and NPB Common  Stock,  it
being their  intention that the holders of NPB Common Stock and Elverson  Common
Stock shall not receive two dividends,  or fail to receive one dividend, for any
single calendar quarter. In coordinating their respective dividends, ENB and NPB
have agreed that the ENB dividend  which would normally be payable on January 1,
1999 to shareholders of record on December 15, 1998 will be payable December 31,
1998, and the former ENB  shareholders  who are NPB  shareholders  on the record
date for the NPB dividend payable in the first quarter of 1999 will receive that
dividend in full.

Conditions to the Merger

         The obligations of NPB and Elverson to effect the Merger are subject to
various conditions, which include the following:

         (a) the Merger  Agreement  shall have been duly approved by the holders
of NPB Common Stock and Elverson Common Stock;

         (b) all necessary governmental approvals for the Merger shall have been
obtained, and all waiting periods required by law or imposed by any governmental
authority   with   respect  to  the  Merger   shall  have   expired   (see  "The
Merger--Regulatory Approvals");

         (c) there  shall not be any  order,  decree,  or  injunction  in effect
preventing  the  completion  of the  transactions  contemplated  by  the  Merger
Agreement;

         (d) there  shall have been  delivered  to each of NPB and  Elverson  an
opinion  of its  counsel  or a letter  from  its  independent  certified  public
accountants  that,  among other  things,  the Merger will be treated for federal
income tax purposes as a  "reorganization"  within the meaning of Section 368(a)
of the Code (see "The Merger--Certain Federal Income Tax Consequences"); and

         (e) NPB and  Elverson  shall each have  received  an  opinion  from its
respective  independent  certified  public  accountants  that the Merger will be
treated as a pooling of interests  for financial  accounting  purposes (see "The
Merger--Accounting Treatment").

                                       38
<PAGE>

         In  addition to the  foregoing,  the  obligations  of each party to the
Merger Agreement are conditioned on (i) the accuracy in all material respects as
of  July  21,  1998  and as of the  Effective  Date of the  representations  and
warranties of the other party, except as to any representation or warranty which
specially relates to an earlier date and except as otherwise contemplated by the
Merger Agreement, (ii) the other party's performance in all material respects of
all covenants and obligations  required to be performed by it at or prior to the
Effective Date and (iii) other  conditions  which are customary for transactions
of   the   type    contemplated    by   the   Merger    Agreement.    See   "The
Merger--Representations  and  Warranties" and "The  Merger--Conduct  of Business
Pending the Merger."

         Except  for  the  requirements  of  shareholder  approval,   regulatory
approvals and the absence of any order,  decree,  or injunction  preventing  the
transactions  contemplated  by the  Merger  Agreement,  each  of the  conditions
described above may be waived in the manner and to the extent  described in "The
Merger--Amendment;  Waivers".  Neither NPB nor  Elverson,  however,  anticipates
waiving  the  conditions  that  it  receive  an  opinion  from  its  independent
accountants  that the  Merger  will be treated  as a pooling  of  interests  for
financial  accounting  purposes  and  an  opinion  of  its  counsel  or  of  its
independent  accountants  that, in the case of NPB, provides among other things,
that the  Merger  will be treated as a  "reorganization"  within the  meaning of
Section 368(a) of the Code, and in the case of Elverson,  addresses, among other
things, the tax consequences of the Merger to Elverson shareholders.

Amendment; Waiver

         Subject to  applicable  law, at any time prior to  consummation  of the
Merger, NPB and Elverson may (a) amend the Merger Agreement, (b) extend the time
for the  performance of any of the obligations or other acts of NPB and Elverson
required  in  the  Merger   Agreement,   (c)  waive  any   inaccuracies  in  the
representations and warranties  contained in the Merger Agreement,  or (d) waive
compliance  with any of the  agreements  or  conditions  contained in the Merger
Agreement,  except for the  requirements  of  shareholder  approval,  regulatory
approvals and the absence of any order,  decree,  or injunction  preventing  the
transactions contemplated by the Merger Agreement.

Termination; Possible Exchange Ratio Increase

         The  Merger  Agreement  may be  terminated  at any  time  prior  to the
Effective  Date by mutual  consent of NPB and Elverson or by either party if (i)
the other party, in any material respect, breaches any representation, warranty,
covenant or other  obligation  contained in the Merger Agreement and such breach
has not been  cured  within  thirty  days from the date  written  notice of such
breach was given to such party  committing  the breach,  (ii) the closing of the
Merger  shall not have  occurred  on or before  February  28,  1999,  unless the
failure of such  occurrence  shall be due to the failure of the party seeking to
terminate the Merger Agreement to perform or observe any agreements  required to
be performed by such party on or before the Closing Date,  (iii) any  regulatory
authority  whose  approval or consent is required  for the  consummation  of the
Merger  issues a definitive  written  denial of such approval or consent and the
time periods for appeals or requests for  reconsideration  have expired, or (iv)
shareholders  of Elverson or NPB do not  approve the Merger  Agreement  at their
respective Meetings.

         In addition,  Elverson may terminate  the Merger  Agreement at any time
during the ten-day period following the Determination  Date, if both (a) the NPB
Market Value is less than $21.60 and (b) the NPB Market  Value  Quotient is less
than the Index Group Standard by 5% or more (an "Index Termination  Event") (see
"The Merger--Terms of the Merger"), provided, however, that the Merger Agreement
would not be so  terminated if NPB elects,  at its sole option,  to increase the
Exchange Ratio to 1.5625.  Elverson may also  terminate the Merger  Agreement at
any time during the ten-day period following the Determination  Date, if the NPB
Market  Value  is less  than  $20.25  ( a "Price  Termination  Event,"  an Index
Termination  Event  and  a  Price  Termination  Event  together,   a  "Financial
Termination  Event").  Thus, the time period for a Financial  Termination  Event
will have ended prior to the NPB and ENB shareholder meetings.

         Elverson may also  terminate the Merger  Agreement if NPB or any of its
subsidiaries  enters into an agreement with a third party  concerning any merger
of NPB with or into such third party or the  acquisition of all of NPB's assets,
or if any person or entity acquires 19.9% or more of the  outstanding  shares of
NPB Common Stock. Finally, Elverson may terminate the Merger Agreement following
receipt of an Acquisition  Proposal (see "The  Merger--No  Solicitation of Other
Transactions"),  but only if the Elverson  Board of Directors  has  concluded in
good faith after  consultation  with its legal and financial  advisors that such
Acquisition  Proposal,  if consummated pursuant to its terms, would result in an
alternative  transaction  more  favorable to  Elverson's  shareholders  than the
Merger.  There can be no assurance  that the Elverson  Board of Directors  would
exercise its right to terminate  the Merger  Agreement  if a  Termination  Event
(i.e.,  any of the  four  conditions  described  in  this  paragraph  and in the
previous paragraph) exists, and if the Elverson Board of Directors does elect

                                       39
<PAGE>

to so terminate the Merger Agreement on account of an Index  Termination  Event,
there can be no assurance  that NPB will elect to increase the Exchange Ratio as
provided in the Merger Agreement.

         Elverson  shareholders  should be aware that the NPB Market Value as of
the Determination Date, on which the occurrence of a Financial Termination Event
and the  subsequent  increase,  if any, in the Exchange Ratio may be determined,
will be based on the  average of the  closing  sale  prices of NPB Common  Stock
during a 20-day trading period ending on the  Determination  Date.  Accordingly,
because the market price of NPB Common Stock between the Determination  Date and
the  Effective  Date,  as well as between  the  Determination  Date and the date
certificates  representing  shares of NPB Common Stock are delivered in exchange
for shares of Elverson Common Stock following  consummation of the Merger,  will
fluctuate  and  possibly  decline,  the value of the NPB Common  Stock  actually
received  by holders of Elverson  Common  Stock may be more or less than (i) the
NPB Market Value or (ii) the value of the NPB Common Stock on the Closing Date.

         The Index  Group  consists  of eight bank or thrift  holding  companies
selected  by NPB and  Elverson  as  being  directly  relevant  for  purposes  of
distinguishing  changes  in NPB's  stock  prices  that  are  unique  from  those
reflective of general changes in comparable companies.  The eight bank or thrift
holding companies are Wilmington Trust Company, WSFS Financial Corporation,  PNC
Financial  Corporation,  Sovereign Bancorp, Inc., Commerce Bancorp, Inc., Fulton
Financial Corp.,  Keystone Financial,  Inc., and JeffBanks,  Inc. If any company
belonging  to  the  Index  Group  declares  or  effects  a  stock  dividend,   a
reclassification, recapitalization, split-up, combination, exchange of shares or
similar  transaction  between the Starting Date and the Determination  Date, the
prices for the common stock of such company shall be appropriately  adjusted. In
the event the common stock of any such company  ceases to be publicly  traded or
there has been an announcement of a proposal for the acquisition or sale of such
company or the  acquisition  by such company of another  company or companies in
transactions  having  a  value  in  excess  of  25%  of  the  acquiror's  market
capitalization, such company will be removed from the Index Group.

         It is not possible to know whether a Financial  Termination  Event will
occur until after the  Determination  Date.  The Elverson Board of Directors has
made no  decision as to whether it would  exercise  its right to  terminate  the
Merger  Agreement  if  there  is a  Financial  or other  Termination  Event.  In
considering  whether to exercise its termination  right in such  situation,  the
Elverson Board of Directors would,  consistent with its fiduciary  duties,  take
into account all relevant  facts and  circumstances  that exist at such time and
would  consult  with its  financial  advisors  and legal  counsel.  The fairness
opinion  received by ENB is dated as of this Proxy  Statement/Prospectus  and is
based on conditions in effect on such date.  Accordingly,  such opinion does not
address NPB's possible  increase in the Exchange  Ratio if an Index  Termination
Event occurs.  Approval of the Merger  Agreement by the shareholders of Elverson
at the  Elverson  Meeting will confer on the  Elverson  Board of  Directors  the
power,  consistent with its fiduciary  duties, to elect to consummate the Merger
in  the  event  of a  Termination  Event  without  any  further  action  by,  or
resolicitation of the votes of, the shareholders of Elverson.

         The NPB Board of Directors  has made no decision as to whether it would
exercise  its right to increase  the  Exchange  Ratio to 1.5625 if the  Elverson
Board of Directors elected to terminate the Merger Agreement upon the occurrence
of an Index Termination  Event. In considering  whether to exercise its right to
increase the Exchange Ratio, the NPB Board of Directors  would,  consistent with
its fiduciary  duties,  take into account all relevant  facts and  circumstances
that exist at such time and would consult with its financial  advisors and legal
counsel.  The fairness  opinion  received by ENB is dated as of the date of this
Proxy  Statement/Prospectus  and is based on  conditions in effect on such date.
Accordingly,  such  opinion  does not  address  NPB's  possible  increase in the
Exchange Ratio if an Index Termination Event occurs.  See "The  Merger--Opinions
of Financial Advisors--Opinion of NPB's Financial Advisor."

Termination Fees

         Elverson has agreed to pay a fee of  $5,000,000 to NPB if NPB is not in
material  breach of the Merger  Agreement and Elverson  fails to consummate  the
Merger  after  either (i) Elverson has  terminated  the Merger  Agreement  after
receiving  an  Acquisition  Proposal  (see  "The  Merger--Termination;  Possible
Exchange   Ratio   Increase"   and  "The   Merger--No   Solicitation   of  Other
Transactions")   or  (ii)  the  Merger  has  not  been  approved  by  Elverson's
shareholders at the Elverson Meeting and, at the time of such Meeting, there has
been an  announcement  by a person or group of  persons  (other  than NPB) of an
offer or  proposal  to acquire  19.9% or more of the shares of  


                                       40
<PAGE>

Elverson  Common Stock then  outstanding,  to acquire,  or merge or  consolidate
with, Elverson, or to purchase all or substantially all of Elverson's assets.

         NPB has agreed to pay a fee of  $1,000,000  to  Elverson if Elverson is
not in material  breach of the Merger  Agreement and NPB fails to consummate the
Merger after the Merger has not been approved by NPB's  shareholders  at the NPB
Meeting.

Expenses

         Elverson and NPB will each pay all costs and expenses incurred by it in
connection with the transactions contemplated by the Merger Agreement, including
fees and  expenses of  financial  consultants,  accountants  and legal  counsel,
except that the cost of printing  and mailing this Proxy  Statement/  Prospectus
will be shared equally by Elverson and NPB.

No Solicitation of Other Transactions

         The Merger  Agreement  provides that  Elverson  shall not, and Elverson
shall not  authorize  or permit any of its  directors,  officers,  employees  or
agents to,  directly  or  indirectly,  (i)  respond  to,  solicit,  initiate  or
encourage any inquiries relating to, or the making of any proposal which relates
to, an  Acquisition  Proposal (as defined  below),  (ii) recommend or endorse an
Acquisition  Proposal,  or (iii)  participate in any discussions or negotiations
regarding an Acquisition Proposal. Elverson has agreed to notify NPB as promptly
as practicable and in reasonable  detail if any inquiries or proposals  relating
to an  Acquisition  Proposal are received by Elverson,  unless it believes  that
such  notification  could  violate the Elverson  Board of  Directors'  fiduciary
duties.

         Notwithstanding the foregoing,  (i) Elverson may furnish or cause to be
furnished  confidential and non-public  information  concerning Elverson and its
businesses,  properties or assets to a third party,  (ii) Elverson may engage in
discussions or negotiations  with a third party,  (iii) following  receipt of an
Acquisition  Proposal,  Elverson  may take and  disclose to its  shareholders  a
position  with  respect to such  Acquisition  Proposal,  and/or  (iv)  following
receipt of an Acquisition Proposal, the Elverson Board of Directors may withdraw
or modify its  recommendation  of the Merger or terminate the Merger  Agreement,
but in respect of the foregoing clause (iv) only to the extent that the Elverson
Board of Directors has concluded in good faith after consultation with its legal
and financial advisors that such Acquisition  Proposal,  if consummated pursuant
to its terms, would result in an alternative  transaction that is more favorable
to Elverson's shareholders than the Merger.

         "Acquisition  Proposal"  means:  (i) any  acquisition  or purchase of a
significant amount of the assets of Elverson, or any equity interest in Elverson
or any  take-over bid or tender offer  (including  an issuer bid or  self-tender
offer) or exchange offer,  consolidation,  plan or arrangement,  reorganization,
consolidation,  business  combination,  sale of substantially all of the assets,
sale  of  securities,  recapitalization,  liquidation,  dissolution  or  similar
transaction involving Elverson (other than the transactions  contemplated by the
Merger  Agreement),  or (ii) any  proposal,  plan or  intention to do any of the
foregoing either publicly announced or communicated to Elverson or any agreement
to engage in any of the foregoing.

         The  obligation  of  Elverson  to effect  the  Merger is subject to the
condition  that the NPB Common Stock  continue to be authorized for quotation on
the National Market tier of the Nasdaq Stock Market.

Exchange of Elverson Stock Certificates

         The  conversion  of Elverson  Common  Stock into NPB Common  Stock will
occur  automatically  on the Effective  Date. As soon as  practicable  after the
Effective  Date, NP Bank,  or a bank or trust company  designated by NPB, in the
capacity of exchange agent (the "Exchange Agent"),  will send a transmittal form
to each  Elverson  shareholder  of record.  The  transmittal  form will  contain
instructions with respect to the surrender of certificates representing Elverson
Common Stock to be exchanged  for  certificates  representing  NPB Common Stock.
Certificates representing shares of NPB Common Stock and checks for cash in lieu
of  fractional  interests in shares of NPB Common Stock will be mailed to former
shareholders of Elverson as soon as reasonably possible following 


                                       41
<PAGE>

the receipt of certificates  representing former shares of Elverson Common Stock
and other related documentation required by the Exchange Agent.

         ELVERSON SHAREHOLDERS SHOULD NOT FORWARD ELVERSON STOCK CERTIFICATES TO
THE  EXCHANGE  AGENT  UNTIL  THEY  HAVE  RECEIVED  TRANSMITTAL  FORMS.  ELVERSON
SHAREHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD.

         Until  the   certificates   representing   Elverson  Common  Stock  are
surrendered  for  exchange  after  completion  of the  Merger,  holders  of such
certificates  will not receive,  and will not be paid dividends or distributions
on, the NPB Common Stock into which such shares have been  converted.  When such
certificates are surrendered,  any unpaid dividends or other  distributions will
be paid without  interest.  For all other purposes,  however,  each  certificate
which  represents  shares of Elverson Common Stock  outstanding at the Effective
Date (other than any dissenting  shares) will be deemed to evidence ownership of
and the right to receive  the  shares of NPB  Common  Stock (and cash in lieu of
fractional  shares) into which those shares have been converted by virtue of the
Merger.  Neither  NPB nor  Elverson  will be liable  to any  holder of shares of
Elverson  Common  Stock for any amount  paid in good faith to a public  official
pursuant to any applicable abandoned property, escheat or similar law.

         All shares of NPB Common  Stock  issued  upon  conversion  of shares of
Elverson  Common Stock shall be deemed to have been issued in full  satisfaction
of all rights  pertaining  to such shares of  Elverson  Common  Stock,  subject,
however,   to  NPB's   obligation  to  pay  any  dividends  or  make  any  other
distributions  with a record date on or prior to the Effective  Date,  which may
have been  declared or made by Elverson on such shares of Elverson  Common Stock
in accordance with the Merger Agreement and which remain unpaid at the Effective
Date.

         No  fractional  shares  of NPB  Common  Stock  will  be  issued  to any
shareholder of Elverson upon completion of the Merger. For each fractional share
that would  otherwise  be issued,  NPB will pay by check an amount  equal to the
product  obtained by  multiplying  the  fractional  share interest to which such
holder would otherwise be entitled by the NPB Market Value.

Regulatory Approvals

         The Merger is subject to  approval  by the OCC under the  federal  Bank
Merger Act ("BMA"),  which requires that the OCC take into consideration,  among
other factors,  the financial and managerial  resources and future  prospects of
the  institutions and the convenience and needs of the communities to be served.
The BMA prohibits the OCC from approving the Merger: (a) if it would result in a
monopoly or be in furtherance of any  combination or conspiracy to monopolize or
to  attempt  to  monopolize  the  business  of banking in any part of the United
States;  or (b) if its effect in any section of the country may be substantially
to lessen  competition  or to tend to create a  monopoly,  or if it would in any
other  manner  be  a  restraint  of  trade,   unless  the  OCC  finds  that  the
anti-competitive  effects  of the Merger are  clearly  outweighed  by the public
interest and the probable  effect of the  transaction in meeting the convenience
and needs of the communities to be served.  The OCC has the authority to deny an
application  if it  concludes  that  the  combined  organization  would  have an
inadequate  capital position or if the acquiring  organization does not meet the
requirements  of the  Community  Reinvestment  Act of 1977.  Under the BMA,  the
Merger may not be consummated  until the fifteenth day following the date of the
OCC  approval,  during which time the United  States  Department  of Justice may
challenge  the Merger on antitrust  grounds.  The  commencement  of an antitrust
action  would  stay  the  effectiveness  of the  OCC's  approval  unless a court
specifically  orders  otherwise.  NP Bank  and  Elverson  filed  an  application
pursuant to the BMA with the OCC on August 19, 1998. The OCC approved the Merger
on October 2, 1998. WHEN THE OCC GRANTED ITS APPROVAL: (i) IT ONLY REFLECTED THE
OCC'S  VIEW THAT THE  TRANSACTION  DOES NOT  CONTRAVENE  APPLICABLE  COMPETITIVE
STANDARDS IMPOSED BY LAW, SAFETY AND SOUNDNESS; (ii) IT IS NOT AN OPINION BY THE
OCC THAT THE  PROPOSED  TRANSACTION  IS  FAVORABLE  TO THE  SHAREHOLDERS  FROM A
FINANCIAL POINT OF VIEW OR THAT THE OCC HAS CONSIDERED THE ADEQUACY OF THE TERMS
OF THE TRANSACTION;  AND (iii) IT IS NOT AN ENDORSEMENT OR RECOMMENDATION BY THE
OCC OF THE MERGER.

         Elverson,  NP Bank  and NPB are not  aware  of any  other  governmental
approvals or actions that are required for consummation of the Merger, except as
described above. Should any such approval or action be required, it is presently
contemplated that such approval or action would be sought. There would, however,
be no assurance that all such regulatory  approvals  would be obtained,  and, if
the Merger were  approved,  there can be no assurance as to the date of any such
approval.  There  can also be no  assurance  that any such  approvals  would not
contain a  condition  or  requirement  which  causes such  approvals  to fail to
satisfy the conditions set forth in the Merger Agreement.  There can likewise be
no assurance that the U.S.  Department of Justice or the  Pennsylvania  Attorney
General will not challenge the Merger, or if such a challenge is made, as to the
result thereof.

Management and Operations after the Merger

         The Surviving Bank will establish a separate  banking  division  called
"Elverson  National  Bank,  A Division  of  National  Penn Bank" (the  "Elverson
Division"),  which will consist of certain of Elverson's  present branch offices
and certain of NP Bank's  present branch  offices.  The Surviving Bank will also
establish the "Elverson  Division Board of Directors" (the "Elverson  Board") to
advise the  Surviving  Bank from time to time  regarding  sales,  marketing  and
expansion  of the  Elverson  Division.  The  Elverson  Board will consist of the
members of Elverson's  Board of Directors at the Effective  Date (the  "Elverson
Continuing  Directors"),  one  executive  officer of NPB who will be selected by
NPB, and such other persons as the Elverson  Board may select from time to time.
NPB has agreed to operate the Elverson  Division and maintain the Elverson Board
in existence for at least five years after the Effective Date, except in certain
circumstances set forth in the Merger Agreement.

         The  directors  and  executive  officers of NP Bank prior to the Merger
will  continue,  in their  respective  capacities,  as directors  and  executive
officers of the  Surviving  Bank.  In addition,  two persons  (each an "Elverson
Nominee")  proposed by  Elverson's  Board of Directors  and approved by NPB will
become  directors of the Surviving  Bank as of the Effective  Date.  NPB and the
Bank have  agreed  to take all steps  necessary  to  ensure  that each  Elverson
Nominee (or any  successor  selected as described  below) is  re-elected  to the
Surviving  Bank's Board of Directors  for each of the five years  following  the
Effective  Date, if he is in office as a director of the  Surviving  Bank on the
annual  election  dates.  If an Elverson  Nominee (or any successor  selected as
described  in this  sentence)  resigns,  dies or is  otherwise  removed from the
Surviving  Bank's Board of Directors prior to the end of such five-year  period,
the Elverson  Continuing  Directors will have the right to select a successor to
such  Elverson  Nominee,  subject to the approval of NPB.  The  selection of the
Elverson Nominees has not been finalized pursuant to the Merger Agreement.

         Upon  completion  of the Merger and  subject  to all  applicable  legal
requirements,  NPB has  agreed  that its Board of  Directors  will  appoint  two
persons  (each an  "Elverson  NPB  Nominee")  proposed  by  Elverson's  Board of
Directors  and approved by NPB to serve as directors of NPB  effective as of the
Effective Date. One Elverson NPB Nominee will serve as a Class I Director with a
term expiring in April 2000,  and the other Elverson NPB Nominee will serve as a
Class II Director  with a term  expiring  in April 2001.  NPB has also agreed to
cause each Elverson NPB Nominee (or any successor  selected as described  below)
to be re-nominated for at least one additional three-year term thereafter. If an
Elverson NPB Nominee (or any successor  selected as described in this  sentence)
resigns,  dies or is otherwise  removed from NPB's Board of Directors during his
term as a director,  the Elverson  Continuing  Directors  will have the right to
select a successor to such Elverson NPB Nominee, subject to the approval of NPB.
The  selection of the Elverson NPB Nominees has not been  finalized  pursuant to
the Merger Agreement.

Employee Benefits and Severance

         Upon  completion of the Merger,  NPB, NP Bank or another NPB subsidiary
will offer  employment  to each person who is then an  employee of Elverson  (an
"Elverson  Employee") in accordance  with the employment and severance  policies
agreed to by NPB and Elverson in the Merger  Agreement  (the "Merger  Employment
Policies").

     Under the Merger Employment Policies, NPB is obligated to provide severance
benefits to each  Elverson  Employee  (other than an Elverson  Employee who is a
party to an employment,  "change-in-control"  or similar agreement) (i) who does
not accept  employment  with NPB (unless  such  Elverson  Employee  has rejected
offers of employment as described  below) or (ii) whose  employment  with NPB is
terminated  without  "cause"  (as  described  


                                       43
<PAGE>

below) within one year after the Effective Date. Severance benefits will consist
of (i) one week's pay (at then  current  levels) for each year and each  partial
year of service (but in no event less than eight week's pay), which will be paid
as  salary  continuation,  (ii) a lump sum  payment  in  respect  of all  unused
vacation time,  which will be paid as soon as practicable  after  termination of
employment,  and (iii) the continuation of all applicable  welfare plan benefits
until  the last day of the month in which the last  week's  salary  continuation
payment is made.  Notwithstanding  the foregoing,  unless previously  terminated
without  cause,  no Elverson  Employee  shall be entitled to severance  benefits
unless such employee  continues in employment  for 30 days  following the actual
consolidation and conversion of the ENB operating system with and into NP Bank's
operating system.

     NPB will not be  obligated  to pay  severance  benefits to (i) any Elverson
Employee  whose  pre-Merger   employment   position  is  maintained  as  it  was
immediately  prior to the Merger;  (ii) any  non-exempt  Elverson  Employee  who
receives  and  rejects any two job offers of equal or higher  salary  grade at a
location  within a 15-mile radius of such  employee's  home, or (iii) any exempt
Elverson Employee who receives and rejects a job offer of equal or higher salary
grade at a location  within a 25-mile radius of such employee's  home.  However,
each full-time  Elverson  Employee who is employed in a non-community  office or
non-lending  staff  position  and who  rejects  a job  offer  described  in this
paragraph or who elects to terminate  employment  with NPB within 365 days after
the Effective Date will be entitled to four weeks of severance benefits.

         Any Elverson  Employee whose  employment  with NPB is terminated by NPB
without cause (as described  below) after one year after the Effective Date will
receive such  severance  benefits  from NPB as are provided  under NPB's general
severance  policy for such  terminations.  Each such employee will be given full
credit for each year of service as an Elverson Employee.

         For the purposes of NPB's severance obligations,  "cause" will mean the
employer's good faith reasonable belief that the employee committed fraud, theft
or  embezzlement,   falsified  corporate  records,   disseminated   confidential
information concerning customers or NPB, NP Bank or any of their employees,  had
documented  unsatisfactory  job performance  under NPB's or NP Bank's  dismissal
policy, or violated NPB's or NP Bank's code of conduct.

         The Merger Agreement also obligated NPB to provide employee benefits to
each  Elverson  Employee  who  becomes  an  employee  of NPB  or  any  of  NPB's
subsidiaries.  As of the Effective Date,  each Elverson  Employee who becomes an
employee of NPB or of any of NPB's  subsidiaries will be entitled to full credit
for each year of service with Elverson for purposes of  determining  eligibility
for  participation  and  vesting,  but not benefit  accrual,  in NPB's  employee
benefit plans,  programs and policies.  The employee benefits provided to former
Elverson Employees after the Effective Date will be substantially similar to the
employee  benefits,  in the aggregate,  provided by NPB or its subsidiary to its
similarly situated employees.  The NPB medical, dental and life insurance plans,
programs  or  policies,  if any,  that  become  applicable  to  former  Elverson
Employees  will not contain any  exclusion  or  limitation  with  respect to any
pre-existing condition of any such employees or their dependents. Subject to the
foregoing, after the Effective Date, NPB may discontinue, amend or convert to an
NPB plan any  particular  benefit or welfare plan of  Elverson,  subject to such
plan's provisions and applicable law.

         The Merger  Agreement  also makes  provision  for the  Elverson  401(k)
Profit Sharing Plan (the "401(k) Plan"), the Elverson Management  Incentive Plan
(the "MIP"),  the Elverson  Employee  Stock  Ownership  Plan (the  "ESOP"),  and
Elverson's  deferred  compensation  arrangements.  As of the Effective Date, the
account  balances  of  employees  under the 401(k)  Plan will become 100 percent
vested and will be merged with and into NPB's  Capital  Accumulation  Plan.  The
ESOP will be  terminated  and,  pursuant to  applicable  law, all accounts  will
become  100  percent  vested  and will be  merged  with and into  NPB's  Capital
Accumulation  Plan. If the Merger occurs prior to December 31, 1998,  the annual
portion of the MIP will be continued  through  December 31, 1998.  If the Merger
occurs  after  December 31, 1998,  the MIP may be continued or  discontinued  as
determined by the NPB Board of Directors.  In any event,  the Elverson  Board of
Directors will determine in good faith, with the consent of NPB, the appropriate
level of payouts to be made under the MIP for 1998. In making its determination,
the Elverson  Board of Directors will  disregard any  extraordinary  expenses or
charges  related to the Merger that would otherwise cause a reduction in payouts
under the MIP. The  calculations  determining  the amounts to be included in the
ESOP,  MIP and  profit  sharing  plans for 1998 will be done prior to making any
deductions  for reserves to be created or expenses  incurred in connection  with
the Merger.

                                       44
<PAGE>

         On the Effective  Date or on January 1, 1999 if the  Effective  Date is
prior to January 1, 1999, deferred compensation arrangements will be terminated,
and subject to any applicable income tax withholding requirements,  all deferred
compensation account balances shall be paid out in cash to plan participants.

Interests of Certain Persons in the Merger

         Share Ownership

         As of the Record Date, the directors and executive officers of Elverson
may be deemed to be the beneficial  owners of 612,705 shares of Elverson  Common
Stock, or 23.58% of the then outstanding shares of Elverson Common Stock.

         As of the Record Date, the directors and executive officers of Elverson
may be deemed to be  beneficial  owners of ____ shares of NPB Common  Stock,  or
_____% of the then outstanding shares of NPB Common Stock.

         As of the Record Date, the directors and executive  officers of NPB are
not the beneficial owners of any shares of Elverson Common Stock.

         As of the Record Date, the directors and executive  officers of NPB may
be deemed to be  beneficial  owners of 441,937  shares of NPB Common  Stock,  or
3.35% of the then outstanding shares of NPB Common Stock.

         Indemnification and Insurance

         The Merger  Agreement  provides that NPB shall indemnify,  defend,  and
hold harmless the directors,  officers,  employees and agents of Elverson (each,
an  "Indemnified  Party")  against all losses,  expenses  (including  reasonable
attorneys' fees), claims,  damages or liabilities and amounts paid in settlement
arising out of actions or omissions or alleged acts or omissions  ("Prior Acts")
occurring  at or  prior  to  the  Effective  Date  (including  the  transactions
contemplated by the Merger  Agreement) to the fullest extent permitted under the
Pennsylvania Business Corporation Law ("PBCL"), including provisions relating to
advances of expenses incurred in the defense of any proceeding, provided however
that the person to whom the  expenses  are  advanced  provides  any  undertaking
required by the PBCL.

         The Merger Agreement further provides that for a period of at least six
years from the Effective Date, NPB shall use its reasonable best efforts,  at no
expense to the  beneficiaries,  to maintain  directors' and officers'  liability
insurance for the  Indemnified  Parties with respect to matters  occurring at or
prior to the  Effective  Date,  or to obtain  coverage  for  Prior  Acts for the
Indemnified  Parties  under the  directors'  and officers'  liability  insurance
policies  currently  maintained  by NPB, in either case,  providing at least the
same  coverage as  currently  maintained  by Elverson and  containing  terms and
conditions which are no less favorable to the beneficiaries;  provided, however,
that in no event shall NPB be obligated to make  premium  payments  which exceed
(for the portion  related to  Elverson's  directors  and  officers)  150% of the
annual premium payments of Elverson's policy in effect as of July 21, 1998.

         Board Representation

         The Merger Agreement  provides that upon consummation of the Merger and
subject to compliance  with all applicable  legal  requirements,  NPB has agreed
that its Board of  Directors  will  appoint two persons  proposed by  Elverson's
Board of Directors and approved by NPB effective  the Effective  Date.  One will
serve as a Class I director  with a term  through  April 2000 and the other will
serve as a Class II  director  with a term  through  April 2001 and each will be
re-nominated  for at  least  one  full  three-year  term  thereafter  (each,  an
"Elverson  NPB  Nominee").  In the event that any Elverson  NPB Nominee,  or any
successor,  resigns,  dies or is otherwise removed from NPB's Board of Directors
prior to the end of such person's full three-year term, the Elverson  Continuing
Directors,  by a plurality  vote,  shall have the right to select such  person's
successor,  subject to NPB's  approval and NPB shall take all  reasonable  steps
necessary to elect such  successor to the NPB Board of Directors.  The selection
of the  Elverson  NPB  Nominees  has not been  finalized  pursuant to the Merger
Agreement.

         In addition to the  foregoing,  as of the Effective  Date,  two persons
(each an "Elverson  Nominee")  proposed by  Elverson's  Board of  Directors  and
approved by NPB will become  directors of the  Surviving  Bank.  NPB and NP Bank
have agreed to take all steps necessary to ensure that the Elverson Nominees, or
their  successors,  are reelected to the

                                       45
<PAGE>

Surviving  Bank's Board of Directors  for each of the five years  following  the
Effective  Date if such  persons are in office as directors of NPB on the annual
election  dates.  If an Elverson  Nominee or any successor  resigns,  dies or is
otherwise  removed from the Surviving Bank's Board of Directors prior to the end
of such five year period,  the  Elverson  Continuing  Directors,  by a plurality
vote, will have the right to select a successor, subject to approval of NPB. The
selection of the Elverson Nominees has not been finalized pursuant to the Merger
Agreement.

         Upon  consummation  of the Merger and  subject to  compliance  with all
applicable legal requirements, the Surviving Bank will establish and operate the
Elverson Division. The Elverson Division will consist of certain Elverson branch
offices and certain of NP Bank's present branch offices. The Surviving Bank will
also  establish  the  Elverson  Board to advise the  Surviving  Bank's  Board of
Directors  from time to time  regarding  sales,  marketing  and expansion of the
Elverson Division.  The Elverson Board will consist of the members of Elverson's
Board of Directors at the Effective Date, an NPB executive  officer  selected by
NPB and such other  persons as the Elverson  Board may select from time to time.
Elverson's  non-employee directors as of July 21, 1998 who become members of the
Elverson Board will receive  annual  director  compensation  equal to the annual
director  compensation  received by them as of July 21, 1998.  NPB has agreed to
operate the Elverson  Division and maintain the Elverson  Board in existence for
at least five years after the Effective  Date,  except as otherwise  provided in
the Merger Agreement.

         Management Incentive Plan

         If the Merger occurs prior to December 31, 1998,  the annual portion of
the MIP shall be continued through December 31, 1998. If the Merger occurs after
December 31, 1998, the MIP may be continued or discontinued as determined by the
NPB Board of  Directors.  In any event,  the Elverson  Board of Directors  shall
determine  in good faith,  with the  consent of NPB,  the  appropriate  level of
payouts to be made  under the MIP for 1998.  In making  its  determination,  the
Elverson Board of Directors will disregard any extraordinary expenses or charges
related to the Merger that would  otherwise  cause a reduction in payouts  under
the MIP.

         Stock Options

         As a result of the Merger  Agreement  and as  provided  in the ENB 1996
Stock Incentive Plan, all options issued and outstanding have become 100 percent
vested  and  immediately  exercisable.  See "The  Merger--Interests  of  Certain
Persons in the Merger--Employee Benefits."

         The number of options held by the  executive  officers of Elverson that
became 100 percent vested and  exercisable  as a result of the Merger  Agreement
are set forth below.

         Name                       Title                                Vested

     All options to  purchase  Elverson  Common  Stock  issued by  Elverson  and
outstanding  on the Effective  Date will be converted into an option to purchase
NPB Common Stock.  The conversion will be based upon the number of shares of NPB
Common Stock which the  optionholder  would have been entitled to receive in the
Merger if such option was exercised  immediately  prior to the Effective Date at
an exercise  price per share of NPB Common Stock equal to the per share exercise
price of the option to purchase  Elverson  Common Stock  divided by the Exchange
Ratio.

         Continued Employment

         Upon  consummation  of the Merger,  NPB shall offer  employment to each
person who is then an Elverson Employee in accordance with the Merger Employment
Policies  generally  described  below.  See "The  Merger--Employee  Benefits and
Severance."

         Under the  Merger  Employment  Policies,  NPB is  obligated  to provide
severance  benefits to each Elverson  Employee (other than an Elverson  Employee
who is a party to an employment,  "change-in-control"  or similar agreement) (i)
who does not accept  employment  with NPB (unless  such  Elverson  Employee  has
rejected  certain  offers of employment)  or (ii) whose  employment  with NPB is
terminated  without  cause within one year after the Effective  Date.  Severance
benefits  will consist of (i) one week's pay (at then  current  levels) for each
year and each  partial  year of service  (but in no event less than eight week's
pay),  which  will be paid as salary  continuation,  (ii) a lump sum  payment in
respect of all unused  vacation time,  which will be paid as soon as practicable
after  termination of employment,  and (iii) the  continuation of all applicable
welfare plan  benefits  until the last day of the month in which the last week's
salary continuation payment is made.

         Glenn E. Moyer, President and CEO of Elverson, will become President of
the Elverson  Division and President of the Berks County and  Montgomery  County
regions of NP Bank. Mr. Moyer will also become an Executive Vice President of NP
Bank, with additional corporate responsibilities.  See "Information With Respect
to NPB and NP Bank."

         Employee Benefits

         As of the Effective  Date, the account  balances of employees under the
401(k)  Plan will  become 100  percent  vested and will be merged  with and into
NPB's Capital  Accumulation  Plan. The ESOP will be terminated and,  pursuant to
applicable  law, all accounts will become 100 percent  vested and will be merged
with and into NPB's Capital Accumulation Plan. In addition,  consummation of the
Merger  will  cause  the   termination  of  Elverson's   deferred   compensation
arrangement and the distribution of all compensation  previously  deferred under
such arrangement. See "The Merger--Employee Benefits and Severance."

         The Elverson Employees who become employees of NPB shall be entitled to
full  credit  for each year of  service  with ENB for  purposes  of  determining
eligibility   and   vesting  in  NPB's   employee   benefit   plans.   See  "The
Merger--Interest of Certain Persons in The Merger--Continued Employment."

         Certain Relationships with NPB and NP Bank

         John A.  Koury,  Jr.,  a member  of the  Elverson  Board of  Directors,
presently owns a fifty percent interest in OK Ventures III, a partnership  doing
business as Sunset Drive Office Plaza. On December 4, 1997,  Sunset Drive Office
Plaza leased  certain  office  space  located at 1503 Sunset  Drive,  Pottstown,
Pennsylvania,  to NP Bank.  The lease provides for an initial term of five years
and rental  payments in the amount of $69,700  annually.  The lease includes one
(1) five (5) year renewal option with rental  adjustments  based upon changes in
the  consumer  price index and a right of first  refusal.  Effective  October 1,
1998,  NP Bank  exercised  its right of first  refusal for  additional  space at
Sunset Drive Office Plaza for the same rented rate as the original  lease for an
initial  term of five years  (the  "Additional  Lease").  The  Additional  Lease
includes rental payments in the amount of $26,112  annually and includes one (1)
five (5) year renewal option with rental  adjustments  based upon changes in the
consumer price index.

         NP Bank  presently  has  private  banking  relationships  with  certain
Elverson  directors  and  officers.  NP Bank has  extended a home equity line of
credit ("Line of Credit") in the amount of $75,000 to Glenn E. Moyer,  President
and Chief Executive  Officer of Elverson,  and E. Jane Moyer,  Mr. Moyer's wife.
The  Line  of  Credit  is  secured  by a  second  lien on the  Moyers'  personal
residence.  NP Bank has  extended a loan of $811,000  to Boyd C.  Davis,  Jr., a
director  of  Elverson,  which loan is  secured by a pledge of 69,056  shares of
Elverson Common Stock.

Accounting Treatment

         The  Merger is  intended  to  qualify  as a pooling  of  interests  for
accounting and financial  reporting  purposes.  Under this method of accounting,
the recorded  assets and  liabilities  of NP Bank and  Elverson  will be carried
forward to the Surviving Bank at their recorded amounts; income of the Surviving
Bank will include income of both NP Bank and Elverson for the entire fiscal year
of NPB in which  the  Merger  occurs;  and the  reported  income  of NP Bank and
Elverson  for prior  periods  will be  combined  and  restated  as income of the
Surviving Bank. Expenses 

                                       47
<PAGE>

incurred  in  connection  with the Merger  will be  expensed  in the period that
shareholder and regulatory approval related to the Merger are received.

         It is a condition  to  completion  of the Merger that NPB and  Elverson
each  receive  an  opinion  from its  respective  independent  certified  public
accountants  confirming  that the Merger will  qualify as a pooling of interests
for   financial   accounting   purposes.   As  of  the   date  of   this   Proxy
Statement/Prospectus,  neither NPB nor  Elverson  has any reason to believe that
their  respective  independent  certified  public  accountants will be unable to
deliver an opinion that the Merger will  qualify as a pooling of  interests  for
financial accounting purposes.

Certain Federal Income Tax Consequences

     The  following  is a  description  of the  principal  anticipated  material
federal income tax consequences of the Merger to NP Bank, Elverson,  NPB and the
holders of Elverson  Common  Stock.  The  description  is based on the  Internal
Revenue Code of 1986, as amended (the "Code"), its legislative history, existing
and proposed  regulations  thereunder,  judicial decisions and published rulings
and other administrative  interpretations issued by the Internal Revenue Service
("IRS"),  as currently in effect,  all of which are subject to change,  possibly
with retroactive  effect. The discussion does not address all aspects of federal
income tax that may be relevant to particular  holders of Elverson Common Stock.
Thus,  for example,  the  discussion  may not apply to  individuals  who are not
citizens or residents of the United States for federal income tax purposes or to
corporations  not organized under the laws of the United States or its political
subdivisions.  The discussion  does not address any federal estate tax or state,
local or foreign tax considerations  arising in connection with the Merger. EACH
HOLDER OF  ELVERSON  COMMON  STOCK IS  ENCOURAGED  TO CONSULT HIS OR HER OWN TAX
ADVISOR AS TO ANY PARTICULAR FACTS AND  CIRCUMSTANCES  THAT MAY BE UNIQUE TO HIM
OR HER,  AS WELL AS TO ANY  ESTATE,  STATE,  LOCAL OR FOREIGN  TAX  CONSEQUENCES
ARISING  OUT OF THE MERGER  AND/OR ANY SALE  THEREAFTER  OF SHARES OF NPB COMMON
STOCK RECEIVED IN THE MERGER.

     The  obligation  of each of Elverson  and NPB to  consummate  the Merger is
conditioned  upon the receipt of an opinion  from its special  counsel  (Dechert
Price & Rhoads and Ellsworth,  Wiles, Carlton & Waldman, P.C.,  respectively) or
from its independent  certified public  accountants  (Beard & Company,  Inc. and
Grant Thornton LLP,  respectively)  to the effect that the Merger  constitutes a
reorganization  under Section 368(a) of the Code for federal income tax purposes
and that the holders of Elverson  Common Stock will recognize no gain or loss in
connection  with the Merger,  except to the extent that cash is received in lieu
of a fractional  share of NPB Common Stock.  No ruling will be obtained from the
IRS with respect to the federal income tax  consequences of the Merger,  and the
opinions described above are not binding on the IRS or any court.

     Assuming the Merger  constitutes  a tax-free  reorganization  under Section
368(a) for federal income tax purposes:

     1.  Neither  NP  Bank,  NPB nor  Elverson  will  recognize  gain or loss in
connection with the Merger;

     2.  Holders of  Elverson  Common  Stock will  recognize  no gain or loss in
connection  with the Merger,  except to the extent that cash is received in lieu
of a fractional share of NPB Common Stock;

     3. A person's holding period for shares of NPB Common Stock received in the
Merger will include that person's  holding period for shares of Elverson  Common
Stock  surrendered in the Merger,  provided the shares of Elverson  Common Stock
are held as capital assets;

     4. The tax basis of shares of NPB Common Stock  received in the Merger will
be equal to the tax basis of shares of Elverson Common Stock  surrendered,  less
any basis that would be allocable to a fractional  share of NPB Common Stock for
which cash is received;

     5. Cash received in lieu of a fractional  share of NPB Common Stock will be
treated as received in redemption of a fractional share of NPB Common Stock, and
gain or loss  will be  recognized  in  connection  with that  deemed  redemption
subject to the provisions of Section 302 of the Code; and

     6. Cash  received by a holder of Elverson  Common  Stock who has  perfected
dissenters'  rights as to his or her  shares of  Elverson  Common  Stock will be
treated  as a  distribution  in  redemption  of  such  shares,  subject  to  the
provisions and limitations of Section 302 of the Code.

Resale of NPB Common Stock

         The shares of NPB Common  Stock  issued  pursuant to the Merger will be
freely  transferable  under the  Securities  Act except for shares issued to any
Elverson  shareholder  who may be deemed to be an  "affiliate"  of Elverson  for
purposes  of Rule 145  under the  Securities  Act or an  "affiliate"  of NPB for
purposes of Rule 144 under the Securities Act (each an "Affiliate").  Affiliates
will include persons (generally  executive  officers,  directors and 10% or more
shareholders) who control,  are controlled by, or are under common control with,
(i) NPB or Elverson at the time of the Elverson  Meeting or the NPB Meeting,  or
(ii) NPB at or after the Effective Date.

         Rules 144 and 145 will  restrict the sale of shares of NPB Common Stock
received in the Merger by  Affiliates  and certain of their  family  members and
related  interests.  Generally,  during the year  following the Effective  Date,
those  persons  who are  Affiliates  of  Elverson  at the  time of the  Elverson
Meeting,  provided they are not  Affiliates of NPB at or following the Effective
Date, may publicly resell any shares of NPB Common Stock received by them in the
Merger,  subject to certain limitations as to, among other things, the amount of
NPB Common Stock sold by them in any three-month  period and as to the manner of
sale. After the one-year period, such Affiliates may resell their shares without
such  restrictions so long as there is adequate current public  information with
respect to NPB as required by Rule 144.  Persons who are Affiliates of NPB after
the Effective  Date may publicly  resell the shares of NPB Common Stock received
by them in the  Merger  subject to similar  limitations  and  subject to certain
filing requirements specified in Rule 144.

         The ability of Affiliates to resell shares of NPB Common Stock received
in the Merger under Rule 144 or Rule 145 as summarized  herein generally will be
subject to NPB's having  satisfied its public reporting  requirements  under the
Securities Exchange Act of 1934 for specified periods prior to the time of sale.
Affiliates also would be permitted to resell shares of NPB Common Stock received
in  the  Merger  pursuant  to an  effective  registration  statement  under  the
Securities  Act  or  another   available   exemption  from  the  Securities  Act
regulations  requirements.  This Proxy  Statement/Prospectus  does not cover any
resales of shares of NPB Common  Stock  received by persons who may be deemed to
be Affiliates of NPB or Elverson.

         Each  director of Elverson and NPB has entered  into an agreement  with
NPB and Elverson, respectively,  providing that, as an Affiliate, he or she will
not  transfer any shares of NPB Common  Stock  received in the Merger  except in
compliance  with the Securities Act and will make no  dispositions of any shares
of NPB Common Stock or shares of Elverson Common Stock (or any interest therein)
during the period  commencing  30 days prior to the  Effective  Date through the
date on which financial results covering at least 30 days of combined operations
of NPB and Elverson  after the Merger have been made  public.  NPB has agreed to
use its reasonable  best efforts to publish such combined  financial  results no
more than 20 days after the end of the first month after the  Effective  Date in
which there are at least 30 days of post-Merger combined operations.

Appraisal Rights of Dissenting Shareholders

         Under Section  215a(b) of Title 12 of the United States Code  ("Section
215a(b)"),  any holder of shares of Elverson  Common  Stock who does not wish to
accept  the  consideration  pursuant  to the  Merger  has the  right  to seek an
appraisal and be paid the "value" in cash of such holder's Elverson Common Stock
on the Effective Date, provided that such holder complies with the provisions of
Section 215a(b).

         The following is a summary of the material  statutory  procedures to be
followed  by a holder of  Elverson  Common  Stock in order to  dissent  from the
Merger  and  perfect  appraisal  rights  under  Section  215a(b).  This  summary
discusses all material  provisions of Section  215a(b) but is not intended to be
complete and is qualified in its entirety by reference to Section  215a(b),  the
text of  which  is set  forth in Annex D  hereto.  Any  shareholder  considering
demanding  appraisal is advised to consult legal counsel  because the failure to
precisely follow all the necessary legal  requirements may result in the loss of
such appraisal rights.

         Holders of record of Elverson Common Stock who desire to exercise their
appraisal rights must fully satisfy all of the following conditions. Each holder
must either:  (a) vote against the Merger Agreement at the Elverson Meeting;  or
(b) give  notice in writing  at, or prior to,  the  Elverson  Meeting  that such
holder dissents from the Merger, to Elverson National Bank, 83 West Main Street,
Elverson, Pennsylvania 19520-9403, Attention: John A. Koury, Jr., Secretary.

                                       49
<PAGE>

         Voting in favor of the  ratification,  confirmation and approval of the
Merger Agreement, or abstaining from the vote on the ratification,  confirmation
and  approval of the Merger  Agreement  without  providing  the  written  notice
referred  to  above,  will  constitute  a waiver of the  shareholder's  right of
appraisal  and will nullify any written  demand for  appraisal  submitted by the
shareholder.

          This right is further  conditioned  upon written  request of appraisal
being made to NPB,  addressed to National  Penn  Bancshares,  Inc.,  Reading and
Philadelphia Avenues, Boyertown, Pennsylvania 19512, Attention: Sandra L. Spayd,
Secretary,  at any time  within 30 days  after the date of  consummation  of the
Merger.  Such  written  request  must be  accompanied  by the  surrender  of the
dissenting shareholder's Elverson stock certificates.

         Under  Section   215a(b),   the  value  of  the  shares  of  dissenting
shareholders  who give the required  notice is intended to be  ascertained as of
the  Effective  Date by an  appraisal  made by a  committee  of  three  persons,
composed of: (i) one person  selected by the vote of the holders of the majority
of the shares of  Elverson  Common  Stock,  the owners of which are  entitled to
payment in cash;  (ii) one person selected by the Board of Directors of NPB; and
(iii) one person selected by the two so selected.  The valuation  agreed upon by
any two of the  three  appraisers  will  govern.  If the  value  so fixed is not
satisfactory  to any  dissenting  shareholder  who has requested  payment,  that
shareholder may, within five days after being notified of the appraised value of
such holder's  shares,  appeal to the OCC,  which will cause a reappraisal to be
made,  and such  reappraisal  will be final and  binding as to the value of such
shares.

         If, within 90 days from the date of consummation of the Merger,  one or
more of the appraisers is for any reason not selected as provided  above, or the
appraisers  fail to determine  the value of such shares,  the OCC is  obligated,
upon written request of any interested  party, to cause an appraisal to be made,
and such  appraisal  will be final and  binding  on all  parties.  The costs and
expenses of any such  appraisal  are required to be  determined by the committee
and shall be assessed  against NPB.  Unless NPB or the  dissenting  shareholders
seek judicial review of the appraisal, the appraised value of the shares must be
promptly paid to the dissenting  shareholders  by NPB out of the funds deposited
in an escrow account established therefor.

         ATTACHED  TO THIS PROXY  STATEMENT/PROSPECTUS  AS ANNEX E IS A BULLETIN
ISSUED BY THE OCC WITH  RESPECT TO THE METHODS  AND  RESULTS OF OCC  APPRAISALS.
HOLDERS OF ELVERSON  COMMON STOCK SHOULD  CAREFULLY  CONSIDER ANNEX E AND SHOULD
CONSULT  WITH THEIR LEGAL  COUNSEL  REGARDING  THEIR  RIGHT TO DISSENT  FROM THE
MERGER AND TO RECEIVE THE  APPRAISED  VALUE OF THEIR  SHARES OF ELVERSON  COMMON
STOCK.  FAILURE TO FOLLOW  PRECISELY  ANY STEP  REQUIRED  BY SECTION  215A(B) IN
CONNECTION  WITH THE EXERCISE OF APPRAISAL  RIGHTS MAY RESULT IN  TERMINATION OF
SUCH RIGHTS.

                        CERTAIN REGULATORY CONSIDERATIONS

         AS A BANK HOLDING COMPANY,  NPB IS SUBJECT TO REGULATION UNDER THE BANK
HOLDING  COMPANY ACT OF 1956, AS AMENDED  ("BHCA"),  AND TO ITS  EXAMINATION AND
REPORTING  REQUIREMENTS.  THE  FOLLOWING  DISCUSSION  SETS FORTH  CERTAIN OF THE
MATERIAL  ELEMENTS  OF THE  REGULATORY  FRAMEWORK  APPLICABLE  TO  BANK  HOLDING
COMPANIES  AND THEIR  SUBSIDIARIES  AND PROVIDES  CERTAIN  SPECIFIC  INFORMATION
RELEVANT  TO  NPB.  TO THE  EXTENT  THAT  THE  FOLLOWING  INFORMATION  DESCRIBES
STATUTORY  AND  REGULATORY  PROVISIONS,  IT IS  QUALIFIED  IN  ITS  ENTIRETY  BY
REFERENCE TO THE  APPLICABLE  STATUTORY AND REGULATORY  PROVISIONS.  A CHANGE IN
APPLICABLE STATUTES, REGULATIONS OR REGULATORY POLICY MAY HAVE A MATERIAL EFFECT
ON THE BUSINESS OF NPB.

General

         As a bank holding company,  NPB is subject to regulation under the BHCA
and to its examination and reporting requirements.  Under the BHCA, bank holding
companies  may not directly or  indirectly  acquire the  ownership or control of
more than five percent of the voting shares or  substantially  all of the assets
of any company,  including a bank, without the prior approval of, or a waiver of
the  requirement  for such  approval  by, the Board of  Governors of the Federal
Reserve  System  (the  "Federal  Reserve  Board").  In  addition,  bank  holding
companies  are generally  prohibited  under the BHCA from engaging in nonbanking
activities, subject to certain exceptions.

         The earnings of NPB are affected by the  legislative  and  governmental
actions of various regulatory authorities,  including the Federal Reserve Board,
the OCC and the FDIC. In addition, there are numerous governmental  requirements
and regulations which affect the activities of NPB.

Payment of Dividends

         NPB is a legal entity  separate and distinct from its banking and other
subsidiaries.  A major  portion of NPB's  revenues  result from  amounts paid as
dividends to NPB by its  subsidiary,  NP Bank.  The prior approval of the OCC is
required for the payment of any dividend by a national  bank if the total of all
dividends  declared by the board of directors of such bank in any calendar  year
will exceed the sum of such  bank's net  profits for that year and its  retained
net profits for the preceding two calendar years, less any required transfers to
surplus.  Federal law also  prohibits  any national  bank from paying  dividends
which  would be greater  than such  bank's  undivided  profits  after  deducting
statutory bad debt in excess of such bank's allowance for loan losses.

         Under the foregoing dividend  restrictions,  as of June 30, 1998, NPB's
subsidiaries,  without obtaining affirmative  governmental approvals,  could pay
aggregate  dividends  of  $45,868,000  to NPB.  In the first six months of 1998,
NPB's subsidiaries paid $12,816,000 in cash dividends to NPB.

         In addition,  NPB and NP Bank are subject to various general regulatory
policies  and  requirements  relating  to the  payment of  dividends,  including
requirements  to  maintain  adequate  capital  above  regulatory  minimums.  The
appropriate  federal  regulatory  authority is authorized  to  determine,  under
certain circumstances  relating to the financial condition of a national bank or
bank  holding  company,  that the  payment  of  dividends  would be an unsafe or
unsound  practice  and to prohibit  payment  thereof.  The OCC (the  appropriate
agency with respect to NP Bank) has indicated that paying dividends that deplete
a bank's  capital  base to an  inadequate  level  would be an unsound and unsafe
banking practice. The OCC and the Federal Reserve Board have each indicated that
banking  organizations  should  generally  pay  dividends  only  out of  current
operating earnings.

Borrowings; Etc.

         There are also various legal  restrictions  on the extent to which each
of NPB and its nonbank  subsidiaries  can borrow or otherwise obtain credit from
NP Bank.  In general,  these  restrictions  require that any such  extensions of
credit must be secured by  designated  amounts of specified  collateral  and are
limited, as to any one of NPB or such 

                                       51
<PAGE>

nonbank subsidiaries, to ten percent of NP Bank's capital stock and surplus, and
as to NPB and all such nonbank  subsidiaries in the aggregate,  to 20 percent of
NP Bank's capital stock and surplus.

         Under the NBA, if the capital  stock of a national  bank is impaired by
losses or otherwise,  the OCC is authorized to require payment of the deficiency
by  assessment  upon the  bank's  stockholders,  pro  rata  and,  to the  extent
necessary,  if any such  assessment is not paid by any  stockholder  after three
months  notice,  to  sell  the  stock  of such  stockholder  to  make  good  the
deficiency.

         Under Federal Reserve Board policy,  NPB is expected to act as a source
of  financial  strength to NP Bank and to commit  resources  to support NP Bank.
This support may be required at times when,  absent such Federal  Reserve  Board
policy, NPB may not find itself willing or able to provide it.

         Any capital  loans by a bank holding  company to a subsidiary  bank are
subordinate in right of payment to deposits and to certain other indebtedness of
such subsidiary bank. In the event of a bank holding company's  bankruptcy,  any
commitment by the bank holding  company to a federal bank  regulatory  agency to
maintain  the  capital of a  subsidiary  bank will be assumed by the  bankruptcy
trustee and entitled to a priority of payment.

Capital Adequacy

         The  Federal  Reserve  Board  and the OCC  have  adopted  substantially
similar  risk-based  and leverage  capital  guidelines for United States banking
organizations.   Under  these  risked-based   capital  standards,   the  minimum
consolidated  ratio of total capital to risk-weighted  assets (including certain
off-balance  sheet  activities,  such as  standby  letters  of  credit) is eight
percent.  At  least  half of the  total  capital  is to be  composed  of  common
stockholder's  equity,   retained  earnings,  a  limited  amount  of  qualifying
perpetual  preferred  stock and  minority  interests  in the equity  accounts of
consolidated  subsidiaries,  less  goodwill  and  certain  intangibles  ("tier 1
capital" and, together with tier 2 capital,  "total capital").  The remainder of
total capital may consist of mandatory convertible debt securities and a limited
amount of subordinated debt,  qualifying preferred stock and loan loss allowance
("tier 2 capital"). At June 30, 1998, NPB's tier 1 and total capital ratios were
12.43 percent and 13.83 percent,  respectively.  On an NPB and Elverson combined
basis,  such ratios at June 30,  1998,  would have been 12.90  percent and 14.18
percent, respectively.

         In addition, the Federal Reserve Board has established minimum leverage
ratio  guidelines for bank holding  companies.  These  guidelines  provide for a
minimum  leverage ratio of tier 1 capital to adjusted  average  quarterly assets
less certain amounts  ("leverage ratio") equal to three percent for bank holding
companies that meet certain  specified  criteria,  including  having the highest
regulatory  rating.  All other bank holding companies will generally be required
to  maintain  a  leverage  ratio of from at least  four to five  percent.  NPB's
leverage  ratio  at June 30,  1998,  was 9.56  percent.  On an NPB and  Elverson
combined basis,  such ratio at June 30, 1998, would have been 9.49 percent.  The
guidelines also provide that bank holding companies experiencing internal growth
or making  acquisitions  will be expected to maintain  strong capital  positions
substantially above the minimum supervisory levels without significant  reliance
on intangible  assets.  Furthermore,  the  guidelines  indicate that the Federal
Reserve  Board will  continue  to consider a  "tangible  tier 1 leverage  ratio"
(deducting  all  intangibles)  in  evaluating  proposals  for  expansion  or new
activity.  The Federal Reserve Board has not advised NPB of any specific minimum
leverage ratio or tangible tier 1 leverage ratio applicable to it.

         NP Bank is subject to similar capital  requirements adopted by the OCC.
NP Bank had tier 1 and total capital  ratios of 8.84 percent and 10.11  percent,
respectively, and a leverage ratio of 6.47 percent, as of June 30, 1998. The OCC
has not advised NP Bank of any specific minimum leverage ratio applicable to it.

Prompt Corrective Action

         The  Federal  Deposit  Insurance  Act  ("FDIA"),  among  other  things,
requires  the federal  banking  agencies to take "prompt  corrective  action" in
respect  of   depository   institutions   that  do  not  meet  minimum   capital
requirements.  The FDIA  establishes  five capital  tiers:  "well  capitalized";
"adequately capitalized"; "undercapitalized";  "significantly undercapitalized";
and "critically undercapitalized".  A depository institution's capital tier will
depend upon how its capital levels compare to various  relevant capital measures
and certain other factors, as established by regulation.

                                       52
<PAGE>

         The  federal  bank   regulatory   agencies  have  adopted   regulations
establishing relevant capital measures and relevant capital levels applicable to
FDIC-insured  banks.  The relevant capital measures are the total capital ratio,
tier  1  capital  ratio  and  the  leverage  ratio.  Under  the  regulations,  a
FDIC-insured bank will be (i) "well capitalized" if it has a total capital ratio
of ten percent or greater,  a tier 1 capital ratio of six percent or greater and
a leverage  ratio of five  percent or greater and is not subject to any order or
written  directive by the OCC to meet and maintain a specific  capital level for
any capital  measure;  (ii)  "adequately  capitalized" if it has a total capital
ratio of eight  percent or greater,  a tier 1 capital  ratio of four  percent or
greater  and a  leverage  ratio of four  percent or  greater  (three  percent in
certain circumstances) and is not "well capitalized";  (iii)  "undercapitalized"
if it has a total  capital  ratio of less than eight  percent,  a tier 1 capital
ratio of less than four  percent or a leverage  ratio of less than four  percent
(three percent in certain circumstances);  (iv) "significantly undercapitalized"
if it has a total capital ratio of less than six percent, a tier 1 capital ratio
of less than three percent or a leverage ratio of less than three  percent;  and
(v)  "critically  undercapitalized"  if its tangible  equity is equal to or less
than two percent of average  quarterly  tangible  assets.  An institution may be
downgraded  to, or deemed to be in, a  capital  category  that is lower  than is
indicated  by its  capital  ratios  if it is  determined  to be in an  unsafe or
unsound  condition or if it receives an unsatisfactory  examination  rating with
respect to certain matters. As of June 30, 1998, Elverson,  NPB and NP Bank each
had  capital  levels  that  qualify it as being  "well  capitalized"  under such
regulations.

         The FDIA generally prohibits a FDIC-insured depository institution from
making any capital distribution  (including payment of a dividend) or paying any
management  fee to its  holding  company  if the  depository  institution  would
thereafter be "undercapitalized". "Undercapitalized" depository institutions are
subject to growth  limitations and are required to submit a capital  restoration
plan.  The  federal  banking  agencies  may not  accept a capital  plan  without
determining, among other things, that the plan is based on realistic assumptions
and is likely to succeed in restoring the depository  institution's  capital. In
addition,  for a  capital  restoration  plan to be  acceptable,  the  depository
institution's  parent holding company must guarantee that the  institution  will
comply with such capital restoration plan. The aggregate liability of the parent
holding company is limited to the lesser of: (i) an amount equal to five percent
of  the   depository   institution's   total   assets  at  the  time  it  became
"undercapitalized";  and (ii) the amount which is necessary  (or would have been
necessary) to bring the institution  into compliance with all capital  standards
applicable  with respect to such  institution  as of the time it fails to comply
with the plan. If a depository  institution  fails to submit an acceptable plan,
it is treated as if it is "significantly undercapitalized".

         "Significantly undercapitalized" insured depository institutions may be
subject to a number of requirements and  restrictions,  including orders to sell
sufficient  voting stock to become  "adequately  capitalized",  requirements  to
reduce total assets,  and  cessation of receipt of deposits  from  correspondent
banks. "Critically undercapitalized" institutions are subject to the appointment
of a receiver or conservator.  A bank that is not "well  capitalized" is subject
to certain limitations relating to so-called "brokered" deposits.

Depositor Preference Statute

         Under  federal  law,  deposits  and certain  claims for  administrative
expenses and employee  compensation  against an insured  depository  institution
would be afforded a priority over other general unsecured claims against such an
institution,  including federal funds and letters of credit, in the "liquidation
or other resolution" of such an institution by any receiver.

FDIC Insurance Assessments; DIFA

         Effective  January 1, 1996, the FDIC reduced the insurance  premiums it
currently charges on bank deposits insured by the Bank Insurance Fund ("BIF") to
the  statutory  minimum  of $2,000 for "well  capitalized"  banks.  The  Deposit
Insurance  Funds Act of 1996,  which was enacted on September 30, 1996 ("DIFA"),
reduced  the  amount  of  semi-annual   FDIC  insurance   premiums  for  savings
association  deposits  acquired  by banks and insured by SAIF to the same levels
assessed for deposits  insured by BIF. DIFA further  provides for assessments to
be imposed on insured  depository  institutions with respect to deposits insured
by the BIF,  and  continues  the  assessments  currently  imposed on  depository
institutions  with  respect  to  SAIF-insured  deposits,  to pay for the cost of
Financing Corporation funding.

                  INFORMATION WITH RESPECT TO NPB AND NP BANK

         Financial and other information relating to NPB, including  information
relating to NPB's directors and executive  officers,  is set forth in NPB's 1997
Annual Report on Form 10-K (which  incorporated  certain portions of NPB's proxy
statement for its 1998 annual  meeting of  shareholders),  NPB's 1998  Quarterly
Reports  on Form 10-Q and NPB's  1998  Current  Reports  on Form 8-K,  which are
incorporated  by reference  herein,  copies of which may be obtained from NPB as
indicated under  "Available  Information".  See  "Incorporation  of Documents by
Reference".

         It is expected that, at the Effective Date,  Glenn E. Moyer,  President
and Chief Executive Officer and a director of Elverson, will become President of
the  Elverson  National  Bank  Division,  President  of  the  Berks  County  and
Montgomery  County  regions and an Executive Vice President of NP Bank. As such,
Mr. Moyer may be deemed to be an executive  officer of NPB. Mr. Moyer has served
as President,  Chief Executive Officer and a director of Elverson since March 1,
1995;  prior  thereto,  he served as  President,  Berks/Schuylkill  Division  of
Meridian Bank from 1988 to March 1, 1995. During 1997, Elverson paid Mr. Moyer a
salary of $182,600. Mr. Moyer is 47 years old.

         NPB and Mr. Moyer have not  finalized  certain  details of Mr.  Moyer's
employment but anticipate that his total compensation,  including salary, bonus,
benefits and stock options,  will be at a level  commensurate with that afforded
other executives at NPB and NP Bank in similar executive positions. In addition,
NPB and Mr.  Moyer  anticipate  entering  into a  change  of  control  agreement
containing  provisions similar to those currently in force between NPB and other
executive officers.

                      DESCRIPTION OF NPB CAPITAL SECURITIES

         The  authorized  capital stock of NPB consists of 62,500,000  shares of
common  stock,  no par value  ("NPB  Common  Stock"),  and  1,000,000  shares of
authorized preferred stock ("NPB Preferred Stock"). As of _______________, 1998,
there were  __________  shares of NPB Common  Stock issued and  outstanding,  no
shares  held by NPB as  treasury  stock,  and no shares of NPB  Preferred  Stock
issued  or  outstanding.  There  are no other  shares  of  capital  stock of NPB
authorized,  issued or outstanding. NPB has no options, warrants or other rights
authorized,   issued  or  outstanding  other  than  as  described  herein  under
"Shareholder  Rights  Plan" and  options  and rights  granted  under NPB's stock
compensation and dividend reinvestment plans.

Common Stock

         The  holders  of NPB  Common  Stock are  entitled  to share  ratably in
dividends  when and if declared by NPB's Board of Directors  from funds  legally
available  therefor.  Declaration  and payment of cash  dividends by NPB depends
upon dividend payments by NP Bank, which are NPB's primary source of revenue and
cash flow.  NPB is a legal entity  separate and distinct from its  subsidiaries.
Accordingly,  the right of NPB,  and  consequently  the right of  creditors  and
shareholders  of NPB,  to  participate  in any  distribution  of the  assets  or
earnings  of any  subsidiary  is  necessarily  subject  to the  prior  claims of
creditors  of the  subsidiary,  except to the extent  that  claims of NPB in its
capacity as a creditor may be recognized.

         For legal  limitations  on the ability of NP Bank to pay  dividends  to
NPB, see "Certain Regulatory Considerations--Payment of Dividends" and see NPB's
Annual  Report on Form  10-K for the year  ended  December  31,  1997,  which is
incorporated herein by reference.  See "Incorporation of Documents by Reference"
and "Available Information."

         Prior to the issuance of any NPB Preferred Stock which possesses voting
rights (see "Preferred Stock" below),  the holders of shares of NPB Common Stock
possess  exclusive  voting rights.  Each holder of shares of NPB Common Stock is
entitled to one vote for each share held on matters upon which shareholders have
the right to vote.  NPB  shareholders  are not entitled to cumulate votes in the
election of directors.

         The holders of NPB Common Stock have no  pre-emptive  rights to acquire
any additional shares of NPB Common Stock. In addition,  the NPB Common Stock is
not subject to redemption.

         NPB's articles of  incorporation  authorize NPB's Board of Directors to
issue authorized shares of NPB Common Stock without  shareholder  approval.  NPB
Common Stock is included for quotation on the National Market tier of The Nasdaq
Stock Market. Under Nasdaq National Market rules, approval of NPB's shareholders
is  required  for the  issuance  of  additional  shares of NPB  Common  Stock or
securities  convertible into NPB Common Stock if the issuance of such securities
(i) is in connection  with the  acquisition  of a company,  is not in connection
with a public  offering for cash,  and the  securities  issued have or will have
voting power equal to or exceeding  20% of the voting power  outstanding  before
such issuance;  (ii) is in connection with the acquisition of a company in which
a  director,  officer  of  substantial  shareholder  of NPB has a 5% or  greater
interest  and the  issuance  of the  securities  could  result in an increase in
outstanding  NPB  Common  Stock  or  voting  power  of 5% or  more;  (iii) is in
connection  with a transaction,  other than a public  offering,  at a price less
than the greater of book or market  value in which the shares  issued will equal
20% or more of the shares of NPB Common Stock, or have 20% or more of the voting
power,  outstanding before issuance; or (iv) would result in a change in control
of NPB.  Under  Nasdaq  National  Market  rules,  shareholder  approval  is also
required for the establishment of a stock option or purchase plan in which stock
may be acquired by officers and directors other than pursuant to a broadly-based
plan in which other security holders of NPB or employees of NPB participate. For
a discussion  of the approval of NPB  shareholders  required for the issuance of
the shares of NPB Common Stock issuable to Elverson  shareholders in the Merger,
see "The Meeting-- Votes Required."

         In the event of NPB's liquidation,  dissolution or winding-up,  whether
voluntary of involuntary,  holders of NPB Common Stock will be entitled to share
ratably in any of its assets or funds that are available for distribution to its
shareholders  after the  satisfaction  of its  liabilities  (or  after  adequate
provision is made therefor) and after payment of any liquidation  preferences of
any outstanding shares of NPB Preferred Stock.

                                       55
<PAGE>

Preferred Stock

         NPB's Board of Directors is  authorized  to approve the issuance of NPB
Preferred  Stock,  without any required  approval of  shareholders.  The rights,
qualifications,  limitations  and  restrictions  on each series of NPB Preferred
Stock  issued  will be  determined  by NPB's Board of  Directors  at the time of
issuance and may include, among other things, rights to participating dividends,
voting  and  convertibility  into  shares  of NPB  Common  Stock.  Shares of NPB
Preferred Stock may be issued with dividend, redemption, voting, and liquidation
rights taking  priority over the NPB Common Stock,  and may be convertible  into
NPB Common  Stock,  as  determined  by NPB's Board of  Directors  at the time of
issuance.

Shareholder Rights Plan

         NPB maintains a Shareholder Rights Plan (the "Rights Plan") designed to
protect  shareholders  from attempts to acquire  control of NPB at an inadequate
price.  Under the Rights Plan,  each  outstanding  share of NPB Common Stock has
attached to it one right to purchase one one-hundredth of a share of a series of
junior  participating  preferred  stock  (the  "Series  A  Junior  Participating
Preferred  Stock") at an  exercise  price of $28.89,  as adjusted to reflect all
stock dividends and splits since adoption of the Rights Plan (the "NPB Rights").
The NPB Rights are not currently  exercisable or  transferable,  and no separate
certificates  evidencing  the NPB Rights  will be  distributed,  unless  certain
events occur.

         The NPB Rights become  exercisable  to purchase  shares of the Series A
Junior Participating Preferred Stock if a person, group or other entity acquires
or  commences a tender  offer or an exchange  offer for shares of NPB stock with
19.9% or more of total voting  power.  The NPB Rights also can be exercised if a
person or group who has become a beneficial  owner of shares of NPB Common Stock
equal to 15% of the total shares  outstanding  or with 15% of total voting power
is declared by NPB's Board of Directors to be an "adverse person," as defined in
the Rights Plan.

         After the NPB Rights become exercisable,  under certain  circumstances,
the NPB Rights (other than the NPB Rights held by a 19.9% beneficial owner or an
"adverse  person")  will  entitle the holders to purchase  either  shares of NPB
Common Stock or of the common stock of the  potential  acquirer,  in lieu of the
Series A Junior Participating Preferred Stock, at a substantially reduced price.

         NPB is  generally  entitled to redeem the NPB Rights at $.001 per right
at any time until the tenth business day following  public  announcement  that a
19.9% position has been  acquired.  At any time prior to the date the NPB Rights
have become  non-redeemable,  NPB's Board of Directors can extend the redemption
period.  The NPB  Rights  are  not  redeemable  following  an  "adverse  person"
determination.

Anti-Takeover Charter and Law Provisions

         NPB's articles of incorporation  and bylaws contain certain  provisions
which may have the effect of deterring or  discouraging,  among other things,  a
non-negotiated  tender or  exchange  offer for NPB stock,  a proxy  contest  for
control of NPB, the assumption of control of NPB by a holder of a large block of
NPB stock and the removal of NPB's  management.  These  provisions:  (i) empower
NPB's Board of Directors,  without shareholder  approval, to issue shares of NPB
Preferred  Stock the terms of which,  including  voting power,  are set by NPB's
Board of  Directors;  (ii) divide  NPB's Board of Directors  into three  classes
serving staggered  three-year terms;  (iii) restrict the ability of shareholders
to remove directors;  (iv) require that shares with at least 80% of total voting
power  approve  mergers and other similar  transactions  with a person or entity
holding stock with more than 5% of NPB's total voting power,  if the transaction
is not  approved,  in  advance,  by  NPB's  Board  of  Directors;  (v)  prohibit
shareholders'  actions without a meeting; (vi) require that shares with at least
80%,  67%, or a majority,  of total voting power approve the repeal or amendment
of certain  provisions  of NPB's  articles  of  incorporation;  (vii)  eliminate
cumulative  voting in elections of directors;  and (viii) require advance notice
of nominations for the election of directors and the presentation of shareholder
proposals at meetings of shareholders.

         The  Pennsylvania  Business  Corporation  Law of 1988,  as amended (the
"BCL"),  also contains certain  provisions  applicable to NPB which may have the
effect of  impeding a change in control of NPB.  These  provisions,  among other
things:  (i) require that,  following any  acquisition by any person or group of
20% of a public corporation's voting power, the remaining  shareholders have the
right to receive payment for their shares, in cash, from such person 


                                       56
<PAGE>

or group in an amount  equal to the "fair  value" of the  shares,  including  an
increment  representing  a  proportion  of any value  payable for control of the
corporation,  and (ii) prohibit for five years, subject to certain exceptions, a
"business  combination"  (which  includes  a  merger  or  consolidation  of  the
corporation or a sale,  lease or exchange of assets) with a shareholder or group
of shareholders beneficially owning 20% or more of a public corporation's voting
power.

         In 1990,  Pennsylvania  adopted  certain  amendments  to the BCL.  This
legislation   generally:   (i)  expands   the  factors  and  groups   (including
shareholders) which NPB's Board of Directors can consider in determining whether
an action is in the best interests of the corporation;  (ii) provides that NPB's
Board of Directors  need not consider the interests of any  particular  group as
dominant  or  controlling;  (iii)  provides  that NPB's  directors,  in order to
satisfy  the  presumption  that they  have  acted in the best  interests  of the
corporation,  need not satisfy any greater  obligation or higher burden of proof
with respect to actions  relating to an acquisition or potential  acquisition of
control; (iv) provides that actions relating to acquisitions of control that are
approved by a majority of "disinterested  directors" are presumed to satisfy the
directors'  standard,  unless it is proven by clear and convincing evidence that
the  directors  did not  assent to such  action in good faith  after  reasonable
investigation;  and (v) provides that the fiduciary  duty of NPB's  directors is
solely  to the  corporation  and  may be  enforced  by the  corporation  or by a
shareholder in a derivative action, but not by a shareholder directly.

         The 1990  amendments to the BCL  explicitly  provide that the fiduciary
duty of  directors  shall not be deemed to require  directors  (i) to redeem any
rights under, or to modify or render inapplicable,  any shareholder rights plan;
(ii) to render inapplicable, or make determinations under, provisions of the BCL
relating  to  control   transactions,   business   combinations,   control-share
acquisitions  or  disgorgement  by certain  controlling  shareholders  following
attempts  to  acquire  control;  or (iii) to act as the  board of  directors,  a
committee of the board or an individual  director  solely  because of the effect
such action might have on an acquisition or potential or proposed acquisition of
control of the corporation or the consideration that might be offered or paid to
shareholders  in such an  acquisition.  One of the effects of the 1990 fiduciary
duty statutory  provisions may be to make it more difficult for a shareholder to
successfully  challenge  the actions of NPB's Board of  Directors in a potential
change in control  context.  Pennsylvania  case law appears to provide  that the
fiduciary  duty standard under the 1990  amendments to the BCL grants  directors
the  statutory  authority  to  reject or refuse to  consider  any  potential  or
proposed acquisition of the corporation.

         The  1990  amendments  to the  BCL  also  included  "disgorgement"  and
"control-share  acquisition"  statutes.  The  "disgorgement"  statute  generally
requires  disgorgement  by any  person  or group who or which  has  acquired  or
publicly  disclosed an intent to acquire 20% or more of a  corporation's  voting
power  of any  profit  realized  from  the sale of any  shares  acquired  within
specified time periods of such  acquisition or disclosure if the shares are sold
within eighteen  months  thereafter.  The  "control-share  acquisition"  statute
generally  prohibits  a person  or  group  who or which  exceeds  certain  stock
ownership  thresholds (20%,  33-1/3% and 50%) for the first time from voting the
"control shares" (i.e., the shares owned in excess of the applicable  threshold)
unless voting rights are restored by a vote of disinterested shareholders.

                       COMPARISON OF SHAREHOLDERS' RIGHTS

         Upon  consummation  of the Merger,  holders of Elverson  Common  Stock,
whose rights  presently are governed by Elverson's  articles of association  and
bylaws and the National Bank Act (the "NBA"),  will become holders of NPB Common
Stock.  Accordingly,  their  rights  will  be  governed  by  NPB's  articles  of
incorporation and bylaws and the Pennsylvania  Business Corporation Law of 1988,
as amended (the  "BCL").  Certain  differences  arise from  differences  between
Elverson's  and  NPB's  articles  and  bylaws,  as well as from  differences  in
treatment under applicable laws.

         The following  discussion is not intended to be a complete statement of
all differences  affecting the rights of shareholders,  but summarizes  material
differences and is qualified in its entirety by reference to applicable laws and
the respective articles and bylaws of Elverson and NPB.

Directors

         Nomination

         Elverson's  bylaws permit  nominations for election to Elverson's Board
of Directors to be made by the Board of Directors or by any shareholder entitled
to vote for the election of directors.  Nominations, other than those made by or
on behalf of the existing management of Elverson, must be made in writing and be
delivered  or mailed to the  President of Elverson  and the  Comptroller  of the
Currency, Washington, D.C., not less than 14 days nor more than 50 days prior to
any meeting of the shareholders  called for the election of directors.  However,
if less  than 21 days'  notice  of the  meeting  is given to  shareholders,  the
nomination  shall be mailed or  delivered  to the  President of Elverson and the
Comptroller  of the Currency not later than the close of business on the seventh
day  following  the day on which the notice of the meeting  was  mailed.  To the
extent  known to the  shareholder,  the  notification  must include the name and
address of each  proposed  nominee,  the  principal  occupation of each proposed
nominee,  the total number of shares of Elverson Common Stock that will be voted
for each  proposed  nominee,  the name and  residence  address of the  notifying
shareholder,  and the number of shares of  Elverson  Common  Stock  owned by the
notifying  shareholder.  The chairperson of the meeting, in his discretion,  may
disregard any nomination not made in accordance with the  requirements set forth
above and upon the  chairperson's  instructions,  the vote tellers may disregard
all votes cast for such nominee.

         NPB's  bylaws  permit  nominations  for  election  to  NPB's  Board  of
Directors to be made by the Board of Directors or by any shareholder entitled to
vote  for  the  election  of  directors.   Nominations   for  director  made  by
shareholders  (other than by the Board of  Directors)  must be made, in writing,
delivered  or  mailed  to NPB  not  less  than 14 days  prior  to the  date of a
shareholders'  meeting,  unless less than 21 days notice of the meeting is given
to  shareholders,  in which case such nominations must be submitted within seven
days  following  the mailing of the notice of the meeting to  shareholders.  Any
such notice of nomination must contain the same information, to the extent known
to the notifying shareholder,  as that required to be stated by NPB in its proxy
statement  with respect to nominees of the Board of Directors.  Any  nominations
that  are  not  made in this  manner  or any  votes  cast  at a  meeting  of NPB
shareholders  for any candidate not duly  nominated  may be  disregarded  by the
chairman of the meeting.

         Election

         Pursuant to the NBA, Elverson's  articles of association  establish the
number of directors to be no less than five and no more than fifteen.  The exact
number of  members  of the Board of  Directors  of  Elverson  is  determined  by
resolution of a majority of the full Board of Directors or the affirmative  vote
of a majority of the shareholders  entitled to vote;  however, a majority of the
full Board of  Directors  may not  increase  the number of directors to a number
which  exceeds  fifteen or to a number which  increases  the number of directors
last elected by the shareholders by more than two per year. Currently, there are
seven persons serving on Elverson's  Board of Directors.  The term of office for
each director is one year. Elverson's Board of Directors is not classified.  Any
shareholder  seeking  to elect  its  designees  to a  majority  of the  seats on
Elverson's Board of Directors,  therefore,  could do so at any annual meeting or
at a special meeting called for such purposes.

         NPB's  articles of  incorporation  provide  that its Board of Directors
shall be comprised of not less than eight nor more than 15 directors, the number
of  which  may be  determined  from  time  to time by the  Board  of  Directors.
Presently,  the Board of Directors is comprised of nine members.  NPB's Board of
Directors is divided into three 

                                       58
<PAGE>

classes,  each serving three-year terms, so that approximately  one-third of the
directors are elected at each annual meeting of shareholders.  Classification of
the Board of Directors has the effect of decreasing the number of directors that
could be elected in a single year by any person who seeks to elect its designees
to a majority of the seats on NPB's Board of Directors  and thereby could impede
a change in control of NPB.

         Cumulative Voting

         With respect to all matters on which shareholders are entitled to vote,
shareholders  of  Elverson  Common  Stock are  entitled  to one vote per  share.
Pursuant to the NBA,  shareholders  of national  banks,  such as Elverson,  have
cumulative  voting  rights in the election of  directors.  Accordingly,  in such
elections,  each  shareholder  of Elverson is entitled to as many votes as shall
equal the number of shares  owned,  multiplied  by the number of directors to be
elected, and may cast all such votes for a single nominee or may distribute them
among two or more nominees.

         NPB's shareholders do not have cumulative voting rights.

         Qualification

         Section 72 of the NBA requires  that every  director of a national bank
be a citizen of the United States.  It also requires that at least a majority of
the directors must have resided in the state, territory or district in which the
national  bank is  located,  or at least  within 100 miles of the  location  the
bank's office, for at least one year immediately  preceding their election,  and
must be residents  of such state or within a 100 mile  territory of the location
of the bank during their  continuance  in office (with  certain  exceptions  for
subsidiaries  or  affiliates  of  foreign  banks).  Additionally,  the NBA  also
requires  that every  director must own in his or her own right either shares of
the capital  stock of the bank which he or she is a director in an aggregate par
value not less than $1,000 (or an equivalent interest, as determined by the OCC,
in any company which has control over such bank). A smaller aggregated par value
(i.e., $500) is required for banks with capital that does not exceed $25,000. In
addition, Elverson's bylaws provide that all eligible nominees for director must
reside  within 35 miles of the main  office.  Further,  Elverson's  articles  of
association  provide that members of Elverson's  Board of Directors must consist
of Elverson shareholders.

         NPB's bylaws  provide that no person who has attained the age of 60 and
is not then a director of NPB shall be qualified  for  nomination or election to
NPB's  Board of  Directors.  NPB's  bylaws also  provide  that no person who has
attained the age of 72 shall be qualified  for  nomination  or election to NPB's
Board of Directors.

         Removal

         Neither the NBA nor the  regulations  promulgated by the OCC thereunder
provide for the removal of a director from a national  bank's board of directors
by the bank's  shareholders.  Elverson's  articles of association and bylaws are
also silent on the issue.

         NPB's articles of incorporation provide that any director or the entire
Board of  Directors  may be  removed  from  office at any time,  with or without
cause,  but only by the  affirmative  vote of the holders of  two-thirds  of the
outstanding  shares of NPB Common Stock at a meeting of shareholders  called for
that purpose.

         Vacancies

         Elverson's  bylaws  provide  that  vacancies  occurring on the board of
directors,  including  vacancies  resulting  from an  increase  in the number of
directors,  may be filled by the affirmative vote of a majority of the remaining
directors  even if the number of  remaining  directors  constitutes  less than a
quorum. Any director so chosen shall have a term of office continuing only until
the next election of directors.

         NPB's bylaws  provide that  vacancies on NPB's Board of Directors,  for
whatever  reason,   including  vacancies  resulting  from  death,   resignation,
retirement,  disqualification, or an increase in the number of directors, may be
filled  by a  majority  vote of the  remaining  directors,  even if less  than a
quorum.  Any director elected by NPB's Board of Directors to fill a vacancy will
have a term of office ending at the annual meeting of  shareholders at which the
term of the class to which he has been elected ends.

                                       59
<PAGE>

         Limited Liability

         Elverson's  bylaws  are  silent  on  the  specific  issue  of  personal
liability of a director of Elverson to Elverson's  shareholders  or others.  See
"Comparison of Shareholders' Rights--Directors--Indemnification."

         As  permitted by the BCL,  NPB's bylaws  provide that a director of NPB
shall not be  personally  liable to NPB,  its  shareholders  or others,  for any
action taken or any failure to take any action  unless the director  breached or
failed  to  perform  the  duties  of his  or  her  office  as  set  forth  under
Pennsylvania law and such breach or failure  constitutes  self-dealing,  willful
misconduct or recklessness; provided, however, that there is no such elimination
of liability  arising under any criminal  statute or with respect to the payment
of taxes pursuant to local, state or federal law.

         Indemnification

         Elverson's bylaws provide that directors,  officers and employees,  may
be  indemnified  or  reimbursed  by Elverson  for  reasonable  expense  actually
incurred in actions to which the  directors,  officers and employees are parties
by reason of the performance of their official duties,  provided,  however, that
no person shall be so  indemnified  or  reimbursed  in relation to any matter in
such  action as to which he shall  finally be adjudged to have been guilty of or
liable  for  gross  negligence,  willful  misconduct,  or  criminal  act  in the
performance of his duties to Elverson.

         The bylaws of NPB  provide  for  indemnification  of current and former
directors,  officers, employees and agents of NPB for certain litigation-related
liabilities and expenses to the maximum extent provided by Pennsylvania  law. As
provided  in the BCL,  current and former  directors,  officers,  employees  and
agents of NPB are entitled to  indemnification  in both third party  actions and
derivative  actions  unless there is a court  finding that the act or failure to
act giving rise to the claim for indemnification  constitutes willful misconduct

         Call

         Elverson's articles of association provide that special meetings of the
shareholders may be called by the Board of Directors or any three  shareholders.
A notice of the meeting must be published  for thirty days in a newspaper in the
town,  city, or county where  Elverson is located or mailed to the  shareholders
thirty days in advance of the scheduled meeting. In addition,  Elverson's bylaws
provide that a special meeting of the shareholders may be called by the Board of
Directors or by any ten or more shareholders owning, in the aggregate,  not less
than thirty-five percent of Elverson Common Stock. Such special meeting shall be
called by mailing,  postage prepaid,  not less than ten days nor more than sixty
days  prior to the date  fixed  for such  meeting  to each  shareholder,  at his
address  appearing  on  Elverson's  books,  a notice  stating the purpose of the
meeting.

         Special meetings of NPB shareholders may be called at any time by NPB's
Board of Directors or Chief Executive  Officer or by any other person authorized
by statute.  Under the BCL, NPB  shareholders are not entitled to call a special
meeting of shareholders.

         Notice

         Notice of an annual  Elverson  shareholders'  meeting  must be  mailed,
postage  prepaid,  at least ten days in advance  of the  scheduled  meeting  and
addressed to each shareholder at his address  appearing on Elverson's books. OCC
regulations further require that in certain instances,  such notice must also be
given by certified or registered  mail,  by  publication,  or both.  Pursuant to
Elverson's bylaws,  unless otherwise provided by law, a special meeting shall be
called by mailing,  postage prepaid,  not less than ten days nor more than sixty
days  prior to the date  fixed  for such  meeting  to each  shareholder,  at his
address  appearing  on  Elverson's  books,  a notice  stating the purpose of the
meeting.

         NPB's bylaws provide that written notice of the date, place and time of
all meetings of  shareholders,  and of the general  nature of the business to be
transacted  at special  meetings,  shall be mailed by  first-class  mail to each
shareholder  of  record  entitled  to vote at the  meeting  at  least 10 days in
advance of the meeting  date,  unless a greater  period of notice is required by
law in a particular case.

         Quorum

         The  presence,  in person or by proxy,  of the holders of a majority of
the outstanding shares entitled to vote at a meeting constitutes a quorum for an
Elverson  shareholders'  meeting. An Elverson meeting called for the election of
directors  may be  adjourned  for any  period up to 60 days.  If a quorum is not
present at an  Elverson  shareholders  meeting,  no business  may be  transacted
except to adjourn to a future time.

         NPB's bylaws provide that the presence,  in person or by proxy,  of NPB
shareholders entitled to cast a majority of the votes which all shareholders are
entitled to cast on a  particular  matter  constitutes  a quorum for purposes of
considering such matter.

Required Shareholder Vote

         General

         With respect to all matters on which shareholders are entitled to vote,
shareholders of Elverson Common Stock are entitled to one vote per share.

         Subject to the voting rights of any series of NPB Preferred  Stock then
outstanding,  if any  (see  "Description  of NPB  Capital  Securities--Preferred
Stock"), the holders of NPB Common Stock possess exclusive voting rights of NPB.
Each  holder of NPB Common  Stock is entitled to one vote for each share held of
record. For general corporate action of the shareholders of NPB, the affirmative
vote of a majority  of the votes cast at a meeting of  shareholders  is required
for approval.  Abstentions  with respect to any matter are not considered  votes
"cast" under Pennsylvania law.

         Fundamental Changes

         Elverson's  articles of association are silent  regarding a fundamental
change.  Pursuant to the NBA,  Elverson  may merge or  consolidate  with another
national bank by an affirmative vote of Elverson's  shareholders owning at least
two-thirds of the shares of capital stock outstanding.

         NPB's  articles  of  incorporation  require  that  a  plan  of  merger,
consolidation,  share exchange,  or asset transfer (in respect of a sale, lease,
exchange or other  disposition of all, or  substantially  all, the assets of NPB
other than in the usual and regular  course of business) or similar  transaction
must be approved by the  affirmative  vote of  shareholders  entitled to cast at
least a majority  of the votes  which all  shareholders  are  entitled  to cast,
except as follows.  NPB's articles of incorporation require the affirmative vote
of  shareholders  with at least 80% of NPB's total  voting  power to approve any
merger,  consolidation,  share  exchange,  asset transfer (in respect of a sale,
lease, exchange or other disposition of all, or substantially all, the assets of
NPB) or similar transaction  involving a shareholder holding 5% or more of NPB's
voting power,  unless the transaction has been approved in advance by a majority
of NPB's directors who are not affiliated with the 5% or more  shareholder.  The
Merger has been unanimously approved by NPB's Board of Directors.

         Amendment of Articles of Incorporation

         As provided by Section 21a of the NBA, amendment of Elverson's articles
of association requires the approval of shareholders of a majority of the voting
shares  of stock  obtained  at a meeting  of the  shareholders  called  and held
pursuant to notice given at least thirty days prior to the meeting.

         NPB's articles of  incorporation  contain two provisions that require a
supermajority  vote of  shareholders  to amend,  repeal  or adopt any  provision
inconsistent with, particular sections of such articles. Amendment or repeal of,
or adoption of any provision inconsistent with, the provisions of NPB's articles
of incorporation  relating to the  classification  of directors,  the filling of
Board vacancies,  or the removal of directors,  requires the affirmative vote of
the holders of  two-thirds of the shares then entitled to vote in an election of
directors.  Amendment  or repeal of, or adoption of any  provision  inconsistent
with, the provisions of NPB's  articles of  incorporation  relating to a merger,
consolidation  or  similar  transaction  with a 5% or  more  shareholder  of NPB
requires the affirmative  vote of shareholders  entitled to cast at least 80% of
the votes which all shareholders of NPB are entitled to cast thereon.

                                       61
<PAGE>

Amendment of Bylaws

         Amendments to Elverson's  bylaws may be made at any regular  meeting of
the Board of Directors by an affirmative  vote of the majority of the members of
Board of Directors of Elverson.

         The  authority to amend or repeal NPB's bylaws is vested in NPB's Board
of Directors,  subject always to the power of the  shareholders of NPB to change
such  action by the  affirmative  vote of a  majority  of the votes  cast by all
shareholders  entitled  to  vote  thereon,  except  that  any  amendment  to the
limitation of directors' liability and indemnification  provisions of the bylaws
requires  the  affirmative  vote of 80% of the members of NPB's  entire Board of
Directors or of shareholders entitled to cast at least 80% of the votes that all
shareholders are then entitled to cast.

Inspection Rights

         Elverson's articles of association and bylaws are silent with regard to
any rights of Elverson's  shareholders to examine the share  register,  books or
records of account and records of the proceedings of Elverson's shareholders and
directors, and to make copies or extracts therefrom.

         As provided in the BCL,  shareholders of NPB, upon written demand under
oath stating the purpose  thereof,  have the right,  for any proper purpose,  to
examine  during usual  business  hours the share  register,  books or records of
account and records of the proceedings of NPB's shareholders and directors,  and
to make copies or extracts therefrom.

Shareholder Rights Plan

         Elverson does not have a shareholder rights plan.

         NPB has adopted a shareholder  rights plan pursuant to which holders of
NPB Common Stock are entitled,  under certain circumstances  generally involving
an  accumulation of shares of NPB Common Stock, to purchase shares of NPB Common
Stocks or common  stock of the  potential  acquiror at a  substantially  reduced
price. See "Description of NPB Capital Securities--Shareholder Rights Plan."

Anti-Takeover Provisions

         The NBA  provides  that a merger or sale of assets by a national  bank,
such as Elverson,  must be approved by the Board of Directors of Elverson and by
the vote of the  holders of at least  two-thirds  of each  class of its  capital
stock.

         The  Change  in Bank  Control  Act  prohibits  a person  or group  from
acquiring  "control" of a national bank unless the OCC has been given sixty days
prior written notice of the proposed acquisition and within that time period the
OCC has not issued a disapproval  or extended for up to another  thirty days the
period during which such a disapproval may be issued.

         NPB is subject to various provisions of the BCL which are triggered, in
general, if any person or group acquires, or discloses an intent to acquire, 20%
or more of the voting power of a covered  corporation,  other than pursuant to a
registered firm  commitment  underwriting  or, in certain cases,  pursuant to an
approving  vote of NPB's is Board of  Directors.  The  relevant  provisions  are
contained in Subchapters 25E through 25H of the BCL.

         Subchapter 25E of the BCL (relating to control  transactions)  provides
that if any  person  or  group  acquires  20% or more of the  voting  power of a
covered corporation,  the remaining  shareholders may demand from such person or
group the fair value of their shares,  including a  proportionate  amount of any
control premium.

         Subchapter  25F of the BCL (relating to business  combinations)  delays
for five years and imposes  conditions upon "business  combinations"  between an
"interested shareholder" and the corporation. The term "business combination" is
defined broadly to include various transactions utilizing a corporation's assets
for purchase price amortization or refinancing  purposes.  For this purpose,  an
"interested  shareholder"  is defined  generally as the  beneficial  owner of at
least 20% of a corporation's voting shares.

                                       62
<PAGE>

         Subchapter  25G of the BCL  (relating  to control  share  acquisitions)
prevents a person who has  acquired 20% or more of the voting power of a covered
corporation  from  voting such shares  unless the  "disinterested"  shareholders
approve such voting rights. Failure to obtain such approval exposes the owner to
the risk of a forced  sale of the  shares  to the  issuer.  Even if  shareholder
approval is obtained, the corporation is also subject to Subchapters 25I and 25J
of the BCL.  Subchapter 25I provides for a minimum  severance payment to certain
employees terminated within two years of the approval.  Subchapter 25J prohibits
the  abrogation  of  certain  labor  contracts  prior  to their  stated  date of
expiration.

         Subchapter  25H of the BCL  (relating to  disgorgement)  applies in the
event that (i) any person or group  publicly  discloses that the person or group
may acquire  control of the  corporation  or (ii) a person or group acquires (or
publicly  discloses  an offer or intent to  acquire)  20% or more of the  voting
power of the  corporation  and, in either case,  sells  shares  within 18 months
thereafter. Any profits from sale of equity securities of the corporation by the
person or group  during the 18-month  period  belong to the  corporation  if the
securities  that were sold were acquired during the 18-month period or within 24
months prior thereto.

         Subchapters  25E  through  25H of the BCL  contain  a wide  variety  of
transactional  and status  exemptions,  exclusions  and safe harbors,  including
certain "opt-out" opportunities.  NPB has not opted out of any of the provisions
of Subchapters 25E through 25H of the BCL.

         In addition,  the fiduciary duty standards applicable to NPB's Board of
Directors,   under  the  BCL  and  certain   provisions  of  NPB's  articles  of
incorporation  and bylaws,  may have the effect of  deterring  or  discouraging,
among other things, a  non-negotiated  tender or exchange offer for NPB stock, a
proxy  contest for  control of NPB by a holder of a large block of NPB's  stock,
and  the  removal  of  NPB's   management.   See  "Description  of  NPB  Capital
Securities--Anti-Takeover Charter and Law Provisions."

Dissenters Rights

         As  required  by  the  NBA,  any  shareholder  of  a  national  banking
association, who has voted against a merger agreement at its shareholder meeting
or has given notice to such national banking  association in writing at or prior
to the  shareholders  meeting that such  shareholder  dissents  from the merger,
shall be entitled to receive the "value" of the shares held by that  shareholder
at the time the merger  agreement is approved by the OCC,  upon written  request
made to the entity into which the national  banking  association is being merged
at any  time  within  30  days  following  the  effective  date  of the  merger,
accompanied  by the  surrender of such  shareholder's  stock  certificates.  The
relevant  portions of the statutory  dissenters  procedures are attached to this
Proxy  Statement/Prospectus  as Annex D. Shareholders electing to exercise their
dissenters  rights  under the NBA may not vote for the  merger  agreement.  If a
shareholder  returns a signed  proxy but does not  specify  a vote  against  the
merger  agreement  or does not give a direction  to  abstain,  the proxy will be
voted for the merger  agreement,  which  will have the  effect of  waiving  that
shareholder's  dissenters  rights.  Elverson's  shareholders  have the  right to
dissent to the Merger Agreement. See "The Merger--Appraisal Rights of Dissenting
Shareholders."

         Under the BCL, a shareholder of a Pennsylvania corporation is generally
entitled to receive  payment of the fair value of such  shareholder's  shares if
such shareholder duly exercises its dissenters' rights with respect to a plan of
merger or consolidation,  share exchange, asset transfer, division or conversion
to which  such  corporation  is a party,  unless  the shares are (i) listed on a
national  securities  exchange  or  (ii)  held of  record  by  more  than  2,000
shareholders.  The foregoing  market  exceptions do not apply,  and  dissenters'
rights  generally  are available in respect of (i) shares that are not converted
solely into shares of the  acquiring,  surviving,  new or other  corporation  or
solely into such shares and money in lieu of fractional  shares,  (ii) shares of
any preferred or special class unless the shareholders of the class are entitled
to vote on the plan and such class vote is required for the adoption of the plan
or to  effectuate  the  transaction,  and (iii)  shares which under the plan are
treated  differently  from  shares of the same class or series and which are not
entitled to vote as a special  class.  The BCL allows a  corporation  to provide
dissenters' rights notwithstanding the statutory exceptions,  but NPB's articles
of  incorporation  and bylaws do not require such optional  dissenters'  rights.
Under the BCL,  if a plan of  merger or  consolidation,  share  exchange,  asset
transfer,  division or conversion is adopted by the directors only,  without any
shareholder  approvals required,  the shareholders have no statutory dissenters'
rights in respect of the plan other than optional  dissenters'  rights,  if any,
granted by the corporation.

         NPB's  shareholders do not have dissenters'  rights with respect to the
Merger.

Pre-Emptive Rights

         Pursuant to  Elverson's  articles of  association,  in the event of any
increase of the capital of Elverson by the sale of  additional  Elverson  Common
Stock,  each  stockholder  shall be entitled  to  subscribe  to such  additional
Elverson  Common Stock in proportion to the number of shares of Elverson  Common
Stock  owned by him  before the stock  increased,  except  that such  holders of
Elverson Common Stock shall not have any such pre-emptive  rights to purchase or
subscribe  for any shares of  Elverson  Common  Stock (i) for all or any part of
100,000  shares of authorized  but unissued  Elverson  Common Stock which may be
issued from time to time by  Elverson  pursuant to any  employee  stock  option,
employee stock purchase or similar  employee  benefit plan adopted by Elverson's
Board of Directors or (ii) for all or any part of any shares of  authorized  but
unissued Elverson Common Stock which may be issued from time to time by Elverson
pursuant  to a  dividend  reinvestment  plan  adopted  by  Elverson's  Board  of
Directors  which may provide for the  purchase  of shares  with  voluntary  cash
contributions  from participants in amounts not to exceed $2,000 per quarter and
$8,000 annually in which  participation is offered to all stockholders of record
of Elverson on an equal  basis.  Elverson's  Board of  Directors  shall have the
power to  prescribe a  reasonable  period of time within  which the  pre-emptive
rights  to  subscribe  to the  new  shares  of  Elverson  Common  Stock  must be
exercised.

         Holders of NPB Common Stock do not have  pre-emptive  rights to acquire
NPB Common Stock or any other securities of NPB.

Dividends

         Generally,  federal law prohibits  national banks from withdrawing,  or
permitting  to be withdrawn,  either in the form of dividends or otherwise,  any
portion of its capital.  Federal law also  provides that if losses are sustained
at any time by a national bank equal to or exceeding its undivided  profits then
on hand (as defined and  interpreted  by  regulation),  no dividend may be made.
Additionally,  no dividend may be made by a national bank while it continues its
banking  operations,  in an amount greater than its net profits then on hand (as
defined  and  interpreted  by  regulation),  less its  losses  and bad debts (as
defined and interpreted by regulation).  These capital  limitations do not apply
to a  national  bank's  preferred  stock  dividends  (if any);  however,  if the
undivided  profits of a  national  bank are not  sufficient  to cover a proposed
dividend on its  preferred  stock,  the  proposed  dividend  will  constitute  a
reduction in capital under federal regulations.

         Federal law also  provides  that a national bank may declare a dividend
equal to a certain  amount of its net profits (as  defined  and  interpreted  by
regulation) as it judges  expedient,  except that until its  respective  surplus
fund equals its common  capital,  no dividends  may be declared  unless not less
than  one-tenth  part of its net profits of the preceding half year (in the case
of quarterly or semiannual dividends) or not less than one-tenth part of its net
profits  of the  preceding  two  consecutive  half  years (in the case of annual
dividends) has been carried to the surplus fund.

         Under  federal  laws,  national  banks are also required to receive the
approval of the OCC before  declaring a dividend if the amount of all  dividends
(common and preferred),  including the proposed dividend,  declared by it in any
calendar  year  exceeds  the  total  of its net  profits  of that  year to date,
combined  with its retained  net profits of the  preceding  two years,  less any
required  transfers  to surplus or a fund for the  retirement  of any  preferred
stock. National banks are also required to receive the prior approval of the OCC
for the payment of dividends if the total of all dividends declared by its board
of  directors  in any year will  exceed the total of its net profits (as defined
and  interpreted  by  regulation)  of that year,  combined with its retained net
profits (as defined and  interpreted  by regulation) of the preceding two years,
less any  required  transfers  to  surplus or a fund for the  retirement  of any
preferred stock.  These earning  limitations also apply to dividends on national
bank preferred stock (if any).

         Federal law also provides that if a national bank has preferred  stock,
no dividends  may be declared or paid on its common  stock until all  cumulative
dividends on its preferred stock have been paid in full.

         Additionally,  the OCC has indicated that paying dividends that deplete
a bank's  capital  base to an  inadequate  level  would be an unsafe and unsound
banking practice.  Under the Federal Deposit Insurance Corporation  Improvements
Act of 1991  ("FDICIA"),  an insured  bank may not pay any  dividend  if payment
would cause it to become undercapitalized. In addition, no dividend payments are
permitted  once an  insured  bank is  undercapitalized.  Moreover,  the  Federal
Reserve Board, the OCC and the FDIC have issued policy statements which provided
that bank holding  companies  and FDIC insured banks should  generally  only pay
dividends out of current operating earnings.

                                       64
<PAGE>

         Under the BCL,  a  corporation  may pay cash  dividends  unless,  after
giving effect  thereto (i) the  corporation  would be unable to pay its debts as
they become due in the usual course of its business, or (ii) the total assets of
the  corporation  would be less than the sum of its total  liabilities  plus the
amount that would be needed, if the corporation were to be dissolved at the time
as of which the  distribution is measured,  to satisfy the  preferential  rights
upon dissolution of shareholders whose preferential rights are superior to those
receiving the distribution.  For additional  information regarding NPB's ability
to pay cash dividends,  including regulatory  restrictions,  see "Description of
NPB  Capital   Securities--Common   Stock,"   "Incorporation   of  Documents  by
Reference," and "Available Information."

Voluntary Dissolution

         Pursuant to the NBA, upon the affirmative  vote of stockholders  owning
two-thirds of the shares of a national banking association, the national banking
association may go into liquidation and be closed.

         Under the BCL, if the board of directors of a Pennsylvania corporation,
such as NPB,  recommends  that the corporation be dissolved and directs that the
question be submitted to a vote at a meeting of the corporation's  shareholders,
the corporation may be dissolved upon the affirmative  vote of a majority of the
votes cast by all  shareholders  entitled to vote  thereon  and, if any class of
shares  is  entitled  to vote  thereon  as a class,  the  affirmative  vote of a
majority of the votes cast in each class vote.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

         The  following   unaudited  pro  forma  combined  condensed   financial
statements assume a business combination between NPB and Elverson that qualifies
as a pooling of interests for financial reporting purposes. Under this method of
accounting,  the recorded  assets and  liabilities  of NPB and Elverson  will be
carried  forward to NPB at their  recorded  amounts,  income of NPB will include
income of NPB and  Elverson  for the  entire  fiscal  year in which  the  Merger
occurs,  and the reported  income of NPB and Elverson for prior  periods will be
combined  and  restated  as income  of NPB.  The pro  forma  combined  condensed
financial  statements  are based  upon the  respective  historical  consolidated
financial  statements of NPB and Elverson and should be read in conjunction with
such  historical  financial   statements  and  the  notes  thereto,   which  are
incorporated by reference or set forth in this Proxy  Statement/Prospectus.  The
unaudited  pro forma  combined  condensed  balance  sheet is presented as if the
Merger occurred on the date thereof.  The unaudited pro forma combined condensed
income  statements  are presented as if the Merger  occurred at the beginning of
the earliest period presented in respective income statement.

         The  following  unaudited  pro  forma  combined  financial  information
assumes that the Exchange  Ratio is 1.46875  shares of NPB Common Stock for each
share of  Elverson  Common  Stock.  The  Exchange  Ratio is subject to  possible
adjustment. See "The Merger--Terms of the Merger."

         The unaudited pro forma combined financial information is presented for
illustrative  purposes only and is not  necessarily  indicative of the operating
results or financial  position  that would have  occurred if the Merger had been
consummated  at the beginning of the earliest  period  presented with respect to
the unaudited pro forma combined  condensed income statements or with respect to
the pro forma combined condensed balance sheet, nor is it necessarily indicative
of the future operating results or financial  position of NPB. The unaudited pro
forma  information  does not give effect to any synergies  that may occur due to
the integration of NPB's and Elverson's operations.  Additionally, the unaudited
pro forma combined financial  information  excludes the transaction costs of the
Merger which are immaterial.

         Certain  nonrecurring  adjustments will be recorded in conjunction with
the Merger,  but the amounts of these adjustments cannot be determined until NPB
reviews all  facilities,  operations  and systems of Elverson and  finalizes its
plans with respect to integrating the businesses.  The aggregate amount of these
adjustments  will include costs  associated  with  consolidating  operations and
systems,  severance pay for employee terminations,  early retirement and related
employee benefits and charges to conform accounting  practices.  NPB has not yet
quantified any of these adjustments, and none are reflected in the unaudited pro
forma combined financial information.

            ELVERSON: SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

         Selected  historical  financial  data for Elverson is set forth in this
Proxy Statement/Prospectus at "Summary--Selected Historical Financial Data."


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

         The following section presents management's  discussion and analysis of
the  financial   condition  and  results  of  operations  of  Elverson  and  its
wholly-owned  subsidiaries  for 1995,  1996 and  1997,  as well as the six month
periods ended June 30, 1997 and 1998.

Results of Operations

         Elverson  achieved record net income of $ 2,931,000 or $ 1.14 per share
for the year ended 1997.  This represents an increase of $ 564,000 or 23.8% over
1996's net income of $ 2,367,000 or $ .93 per share.  This  increase in earnings
was  driven by growth  in both net  interest  income  and other  income,  offset
somewhat by related  increases  in other  expenses  and the  provision  for loan
losses.

         Elverson  continued to improve its  performance  relative to two widely
used  performance  measurements:  return on average  assets  (ROA) and return on
average  shareholders' equity (ROE). For 1997, the ROA was 1.14% and the ROE was
12.07%. In 1996, these performance ratios were 1.02% and 11.02%, respectively.

         Elverson recorded net income in 1996 of $ 2,367,000 or $ .93 per share,
compared  with net income in 1995 of $ 1,622,000 or $ .65 per share.  Returns on
average assets and equity were 1.02% and 11.02%,  respectively in 1996, compared
to .75% and 8.41%, respectively in 1995.

         Net Interest Income

         The primary  component of Elverson's net income is net interest income,
which  represents the  difference  between the interest and fee income earned on
earning assets and the interest paid on deposits and other borrowed  funds.  The
level of net interest income results from the  interaction  among the volume and
mix of earning  assets,  the funding  sources  supporting  those  assets and the
interest rates earned on assets  relative to those paid on the funding  sources.
For analytical purposes, net interest income is adjusted to a taxable equivalent
basis to recognize the income tax savings on tax-exempt assets such as municipal
securities and tax-free loans.

         During  1997,  taxable  equivalent  net  interest  income  increased  $
1,728,000 or 16.4%  compared to 1996,  and $ 1,391,000 or 15.3% in 1996 compared
to 1995. The components of these increases are summarized in Table 1.

         The interest rate spread represents the difference between the yield on
interest earnings assets and the rate paid on interest bearing  liabilities on a
taxable equivalent basis. The net interest margin represents net interest income
on a taxable  equivalent  basis as a percentage of average earning assets.  This
ratio is a measurement of how effectively  Elverson  utilizes its earning assets
in relation to the interest  paid to fund them,  and is affected by both the net
interest  spread and the level of  non-interest  bearing  sources of funds.  The
average  balances,  interest income and expense and the average rates earned and
paid for assets and liabilities are found in Table 2.

         Taxable equivalent interest income increased 13.4% from $ 18,404,000 in
1996 to $ 20,863,000  in 1997.  This  increase  reflects  both a $ 22,400,000 or
10.1% growth in average interest earning assets and a 25 basis point increase in
the yield on interest  earning assets.  The growth in average  interest  earning
assets was the result of strong  commercial  loan demand in Elverson's  markets.
Average total loans increased 14.3% or $ 24,540,000 to $ 196,480,000 including a
32.5% or $ 25,821,000  increase in  commercial  loans.  Average  tax-free  loans
increased $ 2,775,000 during 1997. Average  residential  mortgage loans declined
7.9% or $  4,823,000  during  1997 as a result  of  normal  prepayments  and the
origination of more fixed rate loans, which Elverson sells, then adjustable rate
loans, 

                                       73
<PAGE>

which  Elverson  generally  retains.  Also,  in  November  1997,  Elverson  sold
approximately $4,300,000 of adjustable rate residential mortgage loans.

         The yield on interest  earning  assets  increased from 8.29% in 1996 to
8.54% in 1997  primarily the result of a 22 basis point increase in the yield on
total loans. This increase,  from 8.85% to 9.07%,  resulted  generally from a 25
basis point increase in Elverson's prime rate in March 1997, higher repricing on
Elverson's other adjustable rate loans and increased loan fee income.

         Interest  expense  increased  $ 731,000 to $ 8,627,000  which  resulted
generally from the growth in average interest bearing  liabilities  during 1997.
Average interest bearing liabilities were $ 195,525,000 in 1997, $ 15,359,000 or
8.5% higher than 1996.  This  increase  primarily  occurred in the money  market
savings and certificates of deposit categories,  which increased $ 8,211,000 and
$ 7,335,000 respectively. Partially offsetting the net interest income effect of
the liabilities growth was a 15.0% growth in the portion of non-interest bearing
liabilities funding interest earning assets.

         When 1996 is compared to 1995,  Elverson's  tax equivalent net interest
income  increased  $ 1,391,000  or 15.3% to $  10,508,000  and the net  interest
margin  increased 28 basis points to 4.73%.  The  increased tax  equivalent  net
interest income from 1995 to 1996 was due to an 8.4% increase in average earning
assets and an improved net interest margin.  Average earning assets increased to
$ 222,028,000  in 1996 from $  204,867,000  in 1995.  The mix of earning  assets
remains relatively  unchanged from year to year, with loans accounting for 77.4%
of total  earning  assets  in 1996 and  76.6% in 1995.  Average  loans  for 1996
increased  9.6% to $ 171,940,000  primarily in the commercial  loan,  commercial
mortgage and consumer installment loan categories.

         Average deposits for 1996 were $ 199,362,000  which represented an 8.8%
increase from 1995's $ 183,249,000. Average non-interest bearing demand balances
were $ 30,067,000 in 1996 versus $ 25,654,000 in 1995 which reflects an increase
of 17.2%.  The average  balance on NOW  increased to $ 19,906,000 in 1996 from $
19,806,000  in 1995.  This .5%  increase  in NOW  balances  is, in part,  due to
customers'  decisions  to place  funds in the money  market  account  as well as
certificates  of deposit.  Elverson's  average  money  market  account  balances
increased  $  9,712,000  or 24.3%  from  1995.  Average  savings  balances  also
reflected growth of $ 306,000 or 3.2% in 1995.  Average  certificates of deposit
grew by $ 1,573,000 or 1.8% from the previous year.

         Other  funding  sources  include  securities  sold under  agreement  to
repurchase  ("repo")  and  long-term  debt.  Repo,  which is  offered  mainly in
conjunction  with cash management  services,  reflected an average increase of $
3,759,000 or 58.6% from the previous  year.  The increase was  primarily  due to
business checking customers using Elverson's cash management services. Long-term
debt,  representing  borrowings  from the Federal Home Loan Bank,  declined by $
4,387,000 from the previous year's average.  These two categories offer Elverson
alternative funding sources for both its short and long-term requirements.

         The  increased net interest  margin from 1995 to 1996,  4.45% to 4.73%,
and 1996 to 1997, 4.73% to 5.01%,  reflects  management's  efforts to refine the
loan  and  deposit  pricing  process.  The  growth  in the  commercial  loan and
commercial mortgage areas, coupled with relatively stable interest rates, helped
achieve the higher margins.

         Provision for Loan Losses

         The provision for loan losses for 1997 totaled $ 988,000  compared to $
600,000 for 1996 and $ 700,000 for 1995.  The amount of the  provision is based,
among other  factors,  on the amount of net loan  charge-offs,  which  totaled $
635,000 in 1997, $ 280,000 in 1996 and $ 237,000 in 1995. Stated as a percentage
of average loans, net charge-offs were .32% for 1997, .16% for 1996 and .15% for
1995.  The  increased  charge-offs  in  1997  were  the  result  of a $  355,000
charge-off on one large  account.  Elverson  settled this workout in full during
1997.

                                       74

         Other Income

         Total  other  income  grew $  467,000  or  43.8% to $  1,532,000.  This
increase  occurred in all  categories.  Customer  service fees  increased  30.1%
during 1997 due to  Elverson's  increased  deposit and customer  base.  Mortgage
banking activities increased 71.8% to $ 421,000. In November 1997, Elverson sold
a portion of its one-year indexed,  adjustable rate residential  mortgage loans.
This  transaction,  which occurred in order to manage Elverson's future interest
rate risk,  resulted in a $ 161,000 gain. The other category  increased $ 67,000
during  1997 as a result  of a $ 79,000  gain  from  the  sale of a  portion  of
Elverson's student loan portfolio.

         Other income for 1996 totaled $ 1,065,000 which represented a $ 195,000
or 22.4%  increase form 1995.  The areas  showing  significant  increases  were:
mortgage  banking  activities,  an increase of $ 134,000;  and customer  service
fees,  an  increase  of $  58,000.  A  major  portion  of the  mortgage  banking
activities  involved the recognition of mortgage servicing rights, in accordance
with FASB 122, from mortgages originated and sold to the secondary market during
1996.

         Other Expenses

         Other  expenses  for 1997 were $  8,270,000,  $ 938,000 or 12.8% higher
than 1996's  expenses.  However,  Elverson's  efficiency ratio (a measurement of
other  expenses  relative to taxable  equivalent  net interest  income and other
income) declined to 60.18% for 1997 from 63.36% for 1996.

         Salaries and employee  benefits,  which account for the largest portion
of other expenses, increased $ 679,000 to $ 4,336,000. Elverson's average number
of full-time  equivalent employees increased from 103 at year-end 1996 to 123 at
year-end 1997. This increased employee base occurred as a result of the new West
Chester branch and  enhancements to the credit  administration  and Tele-banking
areas.  A second  factor  contributing  to the increase in salaries and employee
benefits  was a  reduction  in the  amount  of  contra  loan  origination  costs
recognized in 1997 due to fewer residential mortgage originations.

         Expenses related to occupancy and equipment  increased $ 98,000 in 1997
reflecting  Elverson's  investment in an additional  branch,  renovations to the
existing branch network and technology enhancements.  Other expenses increased $
161,000 to $ 2,450,000  for 1997.  This increase can be attributed to Elverson's
overall  growth,  normal  inflationary  increases  and  Elverson's  focus on the
disposition of foreclosed real estate.

         Other  expenses  for 1996  totaled $ 7,332,000  which  represented  a $
543,000 or 8.0% increase from 1995.  Salaries and employee benefits increased by
$ 427,000 from 1995 or 13.2%. Substantially all of this increase is attributable
to the annual salary  adjustment,  positions  vacant for a portion of 1995 being
filled  for the  entire  year,  and  additions  to staff as a result  of the new
Sinking Spring branch and added Bank services. In addition, the cost of employee
benefits  increased.  In aggregate,  the increase was tempered by an increase in
the contra  charge to salaries and benefits as a result of mortgage  origination
and prepayment activity in 1996.

         Federal Income Taxes

         The provision  for income taxes for 1997 was $ 1,193,000  compared to $
983,000  in 1996 and $ 611,000 in 1995.  The  effective  tax rate,  which is the
ratio of income tax expense to income  before  income taxes was 28.9% in 1997, a
slight  decrease from 29.3% in 1996 and an increase from 27.4% in 1995.  The tax
rate for all periods was less than the  statutory  rate of 34% due  primarily to
tax exempt securities and loan income. Refer to Note 10 to the December 31, 1997
financial statements for further analysis of federal income tax expense.

Financial Condition

         Total  assets  at  December  31,  1997  were $  274,838,000  which is $
28,285,000 or 11.5% higher than total assets at December 31, 1996.

         Loans Receivable

         Total loans were $ 198,284,000 at year-end 1997, a $ 11,522,000 or 6.2%
increase  from  year-end  1996.   Commercial  and  tax-free  loans  increased  $
21,753,000  and $ 3,471,000  respectively,  during 1997.  Residential  mortgages
declined $ 11,977,000  during 1997 as a result of mortgage  sales to the Federal
National Mortgage  Association and other  institutions.  Additionally,  Elverson
sold a portion of its student  loan  portfolio in 1997.  The  proceeds  from all
these  sales  were  used  to  fund   higher-yielding   investment   and  lending
initiatives. Table 3 provides an analysis of Elverson's loan distribution at the
end of each period indicated.

         Nonperforming Loans

         A loan is generally  placed on nonaccrual when the contractual  payment
of principal or interest has become 90 days past due or  management  has serious
doubts about further  collectibility  of principal or interest,  even though the
loan is currently performing.  Table 5 reflects Elverson's nonaccrual,  past due
and restructured loans as of the dates indicated.

         All of the  nonaccrual  loans at December  31, 1997 are secured by real
estate or otherwise  guaranteed as to repayment.  Management  has not identified
any other  material  potential  problem loans that are not included in the above
table.

         Allowance For Loan Losses

         The  amount  charged  to  operations  and the  related  balance  in the
allowance  for  loan  losses  is based  upon  periodic  evaluations  of the loan
portfolio by management.  These evaluations  consider several factors including,
but not limited to, current  economic  conditions,  loan portfolio  composition,
prior  loan  loss  experience,  trends in  portfolio  volume,  and  management's
estimation of future potential  losses.  Management  believes that the allowance
for loan losses is adequate.  Table 7 is an analysis of the  allowance  for loan
losses for the periods indicated.

         The  increase  in net  charge-offs  in 1997  was  primarily  due to the
charging off of one large commercial loan in the amount of $ 355,000.

         The specific  allocations of the allowance for loan losses are based on
management's evaluation of the risks inherent in the specific portfolios for the
dates indicated.  Amounts in a particular  category may be used to absorb losses
if another  category  allocation  proves to be inadequate.  Table 8 reflects the
allocation of the allowance for loan losses as of the dates indicated.

         Securities

         Elverson's  securities'  portfolio  is intended  to provide  liquidity,
reduce interest rate risk and contribute to earnings while exposing  Elverson to
reduced credit risk.

         Total  investment  securities  increased $  7,953,000  during 1997 to $
49,704,000.  Two factors  contributed to this increase.  First, the net proceeds
from the sale of the one-year  indexed  residential  mortgage  loans,  which was
approximately $ 4,500,000,  were reinvested into tax-free municipal  securities.
Secondly, a portion of the funds received from the Bank's certificate of deposit
growth were invested into securities.

         Table 9 sets  forth  the  carrying  amount of  securities  at the dates
indicated.

         Elverson   maintains  a   securities'   portfolio   for  the  secondary
application of funds as well as a secondary source of liquidity. At December 31,
1997,  securities  having an  amortized  cost of $  18,696,000  were  pledged as
collateral for public funds and other purposes as required or permitted by law.

         Elverson  does not hold any  securities of any one issuer that exceeded
10% of  stockholders'  equity at June 30,  1998,  December 31, 1997 or any prior
period end.

         Table 10 sets forth the maturities  and the weighted  average yields of
securities by contractual maturities at December 31, 1997. Yields on obligations
of states and  political  subdivisions  are not  presented  on a  tax-equivalent
basis.  Mortgage-backed  securities with contractual  maturities after ten years
from December 31, 1997 feature regular repayments of principal and average lives
of three to seven years.

         Deposits

         Total  deposits at year-end 1997 were $ 237,923,000  which reflects a $
27,755,000  increase from year-end 1996. This growth resulted generally from the
opening of the West  Chester  branch in March 1997,  the  introduction  of a new
relationship money market savings product, and a successful year-end certificate
of deposit campaign. Elverson experienced a strong $ 7,534,000 or 22.5% increase
in demand deposits. Money market savings increased $ 10,288,000 and certificates
of deposit  increased $ 9,592,000  from  year-end  1996.  A portion of the money
market savings increase was the result of existing  corporate  deposit customers
choosing the new  relationship  money market  product  rather than holding their
deposits under repurchase agreements.

         The average daily amount of deposits and rates paid on such deposits is
summarized in the following Table:

payments to the federal  government.  Borrowings  under the note option  account
which were used as source of funds were consistent  during 1997 and 1996.  These
borrowings do not represent a significant source of funds for Elverson.

         Capital Requirements/Ratios

         The current economic and regulatory environment has placed an increased
emphasis  on capital  strength.  Capital  must be  evaluated  in the  context of
business risk  exposures,  including asset quality,  interest rate  sensitivity,
liquidity  and earnings  diversification.  At December  31, 1997,  stockholders'
equity  totaled $ 25,740,000 or 9.37% of total assets,  compared to $ 22,798,000
or 9.25% at year-end 1996.

         Elverson  is  subject  to  minimum   risk-based  and  leverage  capital
guidelines  issued  by the  Office  of the  Comptroller  of  the  Currency.  The
measurement  of  risk-based  capital  takes into account the credit risk of both
balance sheet assets and off-balance  sheet  exposures.  These  guidelines state
that for  adequacy  purposes,  the  minimum  ratios of 4% for Tier I  risk-based
capital,  8% for total  risk-based  capital  and 4% for Tier I capital  to total
average assets (leverage ratio) be maintained.  The Office of the Comptroller of
the Currency regulations define a "well capitalized" bank as having minimum Tier
I and total risk-based capital ratios of 6% and 10% respectively,  and a minimum
Tier I leverage  ratio of 5%. As of December  31,  1997,  the Bank  qualified as
"well  capitalized" with Tier I, total risk-based  capital,  and Tier I leverage
ratios of 13.09%, 14.34%, and 10.01%, respectively.

         The following table sets forth the computation of Elverson's regulatory
capital ratios for the dates  indicated.  Elverson  exceeded the minimum capital
levels of the well capitalized category.

         Capital Analysis

         In April 1997,  Elverson  changed its capital  structure  to  4,000,000
authorized shares of common stock,  with a par value of $ 1.25 per share.  Also,
Elverson  issued a 2-for-1  stock split in the form of a 100% stock  dividend in
1997. In 1998, Elverson issued a 5% stock dividend.  The number of common shares
issued were adjusted accordingly.

         Elverson's  cash dividend payout ratio for the years ended December 31,
1997, 1996 and 1995 was 19.30%, 16.13% and 21.54%, respectively.

         Stockholders'   equity  is  adjusted  for  the  effect  of   unrealized
appreciation or depreciation,  net of tax, on securities classified as available
for sale.  At June 30, 1998,  December 31, 1997 and 1996,  stockholders'  equity
included  $  157,000,  $  117,000  and  $  67,000,  respectively  in  unrealized
appreciation.

         The return on average  equity for the years ended  December  31,  1997,
1996 and 1995 was 12.07%, 11.02%, and 8.41%, respectively.

         Interest Rate Sensitivity and Market Risk

         The  operations of Elverson are subject to risk resulting from interest
rate fluctuations to the extent that there is a difference between the amount of
Elverson's   interest   earning  assets  and  the  amount  of  interest  bearing
liabilities that are prepaid/withdrawn, mature or reprice in specified periods.

         The  principal  objective  of  Elverson's   asset/liability  management
activities is to provide consistently higher levels of net interest income while
maintaining   acceptable   levels  of  interest  rate  and  liquidity  risk  and
facilitating the funding needs of Elverson.  Elverson  utilizes an interest rate
sensitivity  model as the primary  quantitative  tool in measuring the amount of
interest rate risk that is present.  The  traditional  maturity "gap"  analysis,
which reflects the volume difference  between interest rate sensitive assets and
liabilities during a given time period, is reviewed  regularly by management.  A
positive  gap  occurs  when the  amount of  interest  sensitive  assets  exceeds
interest sensitive liabilities. This position would contribute positively to net
income in a rising interest rate environment.  Conversely,  if the balance sheet
has more  liabilities  repricing  than  assets,  the balance  sheet is liability
sensitive or negatively gapped.  Management  continues to monitor sensitivity in
order to avoid overexposure to changing interest rates.

         The  operations  of  Elverson  do not  subject it to  foreign  currency
exchange or commodity price risk. Also,  Elverson does not utilize interest rate
swaps, caps or other hedging transactions.

         The following table provides  information  about  Elverson's  financial
instruments  that are sensitive to changes in interest  rates.  For  securities,
loans and deposits, the table presents principal cash flows and related weighted
average interest rates by maturity dates or repricing frequency. Elverson has no
market risk sensitive instruments entered into for trading purposes.

         Liquidity

         Liquidity management ensures that sufficient funding is available, at a
reasonable  cost,  to meet the  potential  cash needs of Elverson and to satisfy
customer deposit withdrawals and credit needs. Liquidity comes from a variety of
sources: the maturing of short-term assets,  available for sale securities,  the
stability  of  existing  core  deposits,  the  ability to attract  new funds and
external  borrowing  capabilities.  Elverson  believes it  maintains  sufficient
liquidity to meet its obligations in a timely and cost-effective manner.

         Year 2000 Compliance

         During  1997,  a committee  was formed  with the goal of ensuring  that
Elverson's  operational and financial systems would not be adversely affected by
year 2000  issues.  The  committee is comprised of members from all areas of the
Company - loan operations,  deposit operations, branch administration,  finance,
security  and  audit - and is  providing  the  Board  of  Directors  and  senior
management  with updates on a regular basis.  Elverson's  Board of Directors and
senior  management are  supporting  all compliance  efforts and believe they are
allocating the necessary resources to complete the project within the timeframes
established by the Board of Directors and bank regulators.

                                       86
<PAGE>

         The  committee  has  developed an  inventory of hardware,  software and
outside  service  providers  that could be  affected  by year 2000  issues,  has
identified  what it believes  are the  critical  areas which  require  immediate
evaluation and testing,  and has begun to develop contingency plans for all core
business  processes.  Elverson's main  operational and financial  system -- Jack
Henry CIF 20/20 -- was year 2000  certified  by the OCC and FFIEC in April 1998.
Additional  third party vendor testing is being  scheduled for the later part of
1998.  Elverson is also  contacting  its large  credit and deposit  customers to
determine  if they are  aware of the  year  2000  issue  and/or  their  level of
compliance.

         Elverson's Board of Directors and management do not expect the costs of
evaluating and testing  Elverson's year 2000  compliance will materially  impact
Elverson's  future  financial  condition  or  results  of  operations,  although
Elverson's  Board of Directors and management  recognize that this is an ongoing
process  and  there  can  be no  assurance  that  additional  costs  may  not be
necessary.

                ELVERSON: MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
            AS OF OR FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997


Results of Operations

         Elverson  recorded net income of $ 1,605,000 or $ .62 per share for the
six months  ended June 30, 1998  compared to $ 1,289,000  or $ .50 per share for
the same period in 1997. This represents an increase of $ 316,000 or 24.5%. This
increase  in  earnings  was  principally  driven by growth in  interest  earning
assets.

         Elverson  continued to improve its  performance  relative to two widely
used  performance  measurements:  return on average  assets  (ROA) and return on
average  shareholders' equity (ROE). For the six months ended June 30, 1998, the
ROA was  1.15%  and the ROE was  12.23%.  For the same  period  in  1997,  these
performance ratios were 1.05% and 11.05% respectively.

         Net Interest Income

         The primary  component of Elverson's net income is net interest income,
which  represents the  difference  between the interest and fee income earned on
earning assets and the interest paid on deposits and other borrowed  funds.  The
level of net interest income results from the  interaction  among the volume and
mix of earning  assets,  the funding  sources  supporting  those  assets and the
interest rates earned on assets  relative to those paid on the funding  sources.
For analytical purposes, net interest income is adjusted to a taxable equivalent
basis to recognize the income tax savings on tax-exempt assets such as municipal
securities and tax-free loans.

         For the six months ended June 30, 1998, taxable equivalent net interest
income was $  6,587,000,  $ 667,000 or 11.3%  higher than for the same period in
1997. The components of this increase are summarized in Table 1.

         Taxable  equivalent  interest income  increased 11.8% from $ 10,090,000
for the six months  ended June 30, 1997 to $  11,283,000  for the same period in
1998. This increase  reflects a $ 30,300,000 or 12.7% growth in average interest
earning assets from June 30, 1997 to June 30, 1998.

         The growth in average  interest earning assets was primarily the result
of a 43.8% or $  17,756,000  increase  in  securities.  This  increase  reflects
several  factors:  the  reinvestment  of  proceeds  received  from  the  sale of
residential  mortgages,  low  commercial  and consumer loan demand in 1998,  and
deposit growth.  Total average loans increased 2.7%.  Average  commercial  loans
increased  18.5% or $  18,308,000  due to the strong  commercial  loan demand in
Elverson's markets during late 1997. Average residential mortgage loans declined
23.9% or $ 14,027,000 as a result of normal prepayments, the origination of more
fixed rate loans,  which  Elverson  sells,  than  adjustable  rate loans,  which
Elverson  retains,  and the November 1997 sale of  approximately  $ 4,500,000 in
one-year indexed mortgages for interest rate risk management considerations.

         The yield on interest  earning  assets  declined from 8.56% for the six
months ended June 30, 1997 to 8.49% for the same period in 1998,  primarily  the
result of a change in the mix of Elverson's earning assets.  During this period,
the percentage of lower-yielding,  short-term and long-term investments to total
earning  assets  increased  from 19.0% to 26.2%  while the  percentage  of loans
declined  from 81.0% to 73.8%.  However,  the yield on total loans did  increase
from 9.05% for the six months  ended June 30,  1997 to 9.23% for the same period
in 1998 due to increased  loan fee income  generated by  prepayment  of mortgage
loans in 1998.

         Interest expense increased $ 526,000 to $ 4,696,000 which resulted from
an 11.1% growth in average  interest  bearing  liabilities from June 30, 1997 to
June 30, 1998. This increase  primarily occurred in the money market savings and
certificates of deposit  categories which increased $ 15,279,000 and $ 9,298,000
respectively.  Partially  offsetting  the  net  interest  income  effect  of the
liabilities  growth was a 23.1% or $  7,487,000  growth in average  non-interest
bearing demand deposits.

         Provision for Loan Losses

         The  provision  for loan losses for the six months  ended June 30, 1998
totaled $ 330,000  compared to $ 518,000 for the same period in 1997. The amount
of the  provision  is based,  among  other  factors,  on the  amount of net loan

                                       88
<PAGE>

charge-offs which totaled $ 107,000 for the six months of 1998 and $ 121,000 for
the  same  period  in  1997.  Stated  as a  percentage  of  average  loans,  net
charge-offs  were .05% and .06% for the six months ended June 30, 1998 and 1997,
respectively.

         Other Income

         Total  other  income was $ 760,000  for the six  months  ended June 30,
1998, an 11.6% or $ 79,000  increase from the same period in 1997. This increase
was primarily the result of increased  mortgage  banking  activities  during the
first six months of 1998 as a result of residential mortgage refinances.  Income
from these activities  totaled $ 212,000 for the six months ended June 30, 1998,
a 66.9% or $ 85,000 increase from the same period in 1997.

         Other Expenses

         Other expenses for the six months ended June 30, 1998 were $ 4,525,000,
$ 429,000 or 10.5%  higher  than the same  period in 1997.  However,  Elverson's
efficiency ratio (a measurement of other expenses relative to taxable equivalent
net interest income and other income)  declined during the same period to 61.66%
for 1998 from 62.07% in 1997.

         Salaries and employee benefits,  which accounts for the largest portion
of other expenses,  increased $ 366,000 to $ 2,494,000. The factors contributing
to this increase include an increased  employee base as a result of enhancements
to the credit  administration and Tele-banking areas, annual merit increases and
increased Elverson-funded health insurance costs.

         Expenses  related to equipment  were $ 403,000 for the six months ended
June 30,  1998 an  increase  of $ 65,000 or 19.2% over the same  period in 1997.
This increase reflects Elverson's investment in technology enhancements in early
1998.

Financial Condition

         Total assets at June 30, 1998 were $ 301,814,000  which is $ 26,976,000
or 9.8% higher than total assets at December 31, 1997.

         Total investment securities increased $ 20,511,000 during the first six
months of 1998 to $ 70,215,000.  Three  factors  primarily  contributed  to this
increase:  low  commercial  and  consumer  loan  volumes  due to  tight  pricing
competition,  $ 13,185,000 in proceeds  from the sale of fixed rate  residential
mortgage loans and a $ 25,726,000 increase in deposits since December 31, 1997.

         Total loans were $ 193,649,000  at June 30, 1998, a $ 4,635,000 or 2.3%
decline  from  year-end  1997.  This  decline  was  primarily  the result of a $
6,026,000 or 12.4% decline in residential mortgages. During the first six months
of 1998, $ 13,185,000 in fixed rate  residential  mortgages were sold due to the
high  level  of  mortgage  refinances  in  the  current  low  rate  environment.
Commercial  loans  experienced  a modest 3.0%  increase to $  117,173,000  since
December 31, 1997.

         Total  deposits at June 30, 1998 were $ 263,649,000  which reflects a $
25,726,000  increase from year-end 1997. This growth can be attributed to strong
growth in non-interest  bearing deposits and the continued success of Elverson's
relationship money market savings product. Elverson experienced a $ 8,426,000 or
20.5%  increase  in demand  deposits  while  money  market  savings  increased $
14,048,000 or 22.5%.

         Allowance for Loan Losses

         The  June 30,  1998  allowance  for loan  losses  was $  3,568,000  and
represented  1.84% of  period-end  loans.  This  compares  with an  allowance at
December  31,  1997 of $  3,345,000  and 1.69% of  loans.  The  adequacy  of the
allowance  will  continue to be examined in light of past loan loss  experience,
current economic  conditions,  size and  characteristics  of the loan portfolio,
volume of non-performing and delinquent loans and other relevant information.

         Non-performing  loans at June 30,  1998  were $ 916,000  compared  to $
2,157,000  at  year-end  1997.  Stated  as a  percentage  of  period-end  loans,
non-performing loans were .47% and 1.10% respectively. This improvement reflects

                                       89
<PAGE>

the successful  resolution  and complete  pay-off of four  non-accrual  accounts
totaling $  973,000.  Non-performing  loans are  defined as all loans 90 days or
more past due and non-accruing loans.

         Capital

         The current economic condition and regulatory environment has placed an
increased emphasis on capital strength. Capital must be evaluated in the context
of business risk exposures,  including asset quality, interest rate sensitivity,
liquidity and earnings  diversification.  At June 30, 1998, stockholders' equity
totaled $ 27,401,000 or 9.08% of total assets, compared to $ 25,740,000 or 9.37%
at year-end 1997.

         Elverson  is  subject  to  minimum   risk-based  and  leverage  capital
guidelines  issued  by the  Office  of the  Comptroller  of  the  Currency.  The
measurement  of  risk-based  capital  takes into account the credit risk of both
balance sheet assets and off-balance  sheet  exposures.  These  guidelines state
that,  for  adequacy  purposes,  the minimum  ratios of 4% for Tier 1 risk-based
capital,  8% for total  risk-based  capital  and 4% for Tier 1 capital  to total
average assets (leverage ratio) be maintained.  The Office of the Comptroller of
the Currency regulations define a "well capitalized" bank as having minimum Tier
1 and total  risk-based  capital ratios of 6% and 10% respectively and a minimum
Tier 1 leverage  ratio of 5%. As of June 30, 1998,  Elverson  qualified as "well
capitalized" with Tier I, total risk-based capital and Tier I leverage ratios of
13.34%, 14.59% and 9.71% respectively.

Quantitative and Qualitative Disclosures About Market Risk

         There has been no  material  change  in  Elverson's  assessment  of its
sensitivity  to  market  risk  since its  presentation  included  in this  Proxy
Statement/Prospectus as of December 31, 1997.

Year 2000 Compliance Update

         Elverson expects to spend  approximately $ 10,000 in 1998 to modify its
computer  information systems enabling proper processing of transactions related
to the year 2000 and beyond. Management has evaluated the appropriate courses of
corrective  action and do not expect the costs of evaluating and testing of year
2000 compliance to materially impact  Elverson's  future financial  condition or
results of operations.

                          INDEPENDENT AUDITOR'S REPORT




To the Board of Directors
Elverson National Bank
Elverson, Pennsylvania


     We have audited the  accompanying  consolidated  balance sheets of Elverson
National  Bank and its  subsidiaries  as of December 31, 1997 and 1996,  and the
related consolidated  statements of income,  stockholders' equity and cash flows
for each of the  three  years in the  period  ended  December  31,  1997.  These
financial  statements  are the  responsibility  of the  Bank's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.


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


     In our opinion,  the consolidated  financial  statements  referred to above
present fairly,  in all material  respects,  the financial  position of Elverson
National  Bank and its  subsidiaries  as of December 31, 1997 and 1996,  and the
results of their  operations and their cash flows for each of the three years in
the period  ended  December  31,  1997 in  conformity  with  generally  accepted
accounting principles.




                                                           BEARD & COMPANY, INC.

ELVERSON NATIONAL BANK AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1.  Significant Accounting Policies
Principles of consolidation:  The consolidated  financial statements include the
accounts of Elverson National Bank (the Bank) and its wholly-owned subsidiaries.
All significant  intercompany  balances and transactions have been eliminated in
consolidation.

Nature of  operations:  The Bank  operates  under a national  bank  charter  and
provides  full  banking  services.  As a national  bank,  the Bank is subject to
regulation  of the Office of the  Comptroller  of the  Currency  and the Federal
Deposit Insurance Corporation. The area served by the Bank is principally Berks,
Chester  and  Lancaster  Counties  in  Pennsylvania.   The  Bank's  subsidiaries
primarily hold certain real estate.

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

Presentation of cash flows:  For the purposes of reporting cash flows,  cash and
cash equivalents include cash on hand, cash and due from banks, interest bearing
deposits with banks, federal funds sold and bankers acceptance notes. Generally,
federal  funds  are  purchased  and  sold  for one day  periods.  Also,  bankers
acceptance notes generally have a maturity within 90 days of purchase date.

Securities:  Securities that management has both the positive intent and ability
to hold to maturity  are  classified  as  securities  held to  maturity  and are
carried at cost,  adjusted for  amortization of premium or accretion of discount
using the  interest  method.  Securities  that may be sold prior to maturity for
asset/liability  management purposes, or that may be sold in response to changes
in interest rates, changes in prepayment risk, to increase regulatory capital or
other similar  factors,  are  classified  as  securities  available for sale and
carried at fair value with adjustments to fair value,  after tax,  reported as a
separate   component  of  stockholders'   equity.   Management   determines  the
appropriate  classification  of debt  securities  at the  time of  purchase  and
re-evaluates such designation at each balance sheet date.

Interest and dividends on securities, including the amortization of premiums and
the accretion of discounts,  are reported in interest income on securities using
the interest method.  Gains and losses on the sale of securities are recorded on
the trade date and are calculated using the specific identification method.

Loans receivable: Loans receivable that management has the intent and ability to
hold for the foreseeable  future or until maturity or payoff are stated at their
outstanding unpaid principal  balances,  net of an allowance for loan losses and
any deferred fees or costs.  Interest income is accrued on the unpaid  principal
balance.  Loan origination  fees, net of certain direct  origination  costs, are
deferred and recognized as an adjustment of the yield  (interest  income) of the
related  loans.  The  Bank  is  generally  amortizing  these  amounts  over  the
contractual life of the loan.

Note 1.  Significant Accounting Policies (Continued)
Loans receivable (continued): A loan is generally considered impaired when it is
probable  the Bank will be unable  to  collect  all  contractual  principal  and
interest  payments due in accordance with the terms of the loan  agreement.  The
accrual of interest is generally  discontinued  when the contractual  payment of
principal  or  interest  has become 90 days past due or  management  has serious
doubts about further  collectibility  of principal or interest,  even though the
loan is currently  performing.  A loan may remain on accrual  status if it is in
the process of collection and is either guaranteed or well secured.  When a loan
is  placed on  nonaccrual  status,  unpaid  interest  credited  to income in the
current year is reversed and unpaid  interest  accrued in prior years is charged
against the allowance  for loan losses.  Interest  received on nonaccrual  loans
generally is either applied  against  principal or reported as interest  income,
according  to  management's  judgment  as to the  collectibility  of  principal.
Generally,  loans are restored to accrual  status when the obligation is brought
current, has performed in accordance with the contractual terms for a reasonable
period  of  time  and  the  ultimate  collectibility  of the  total  contractual
principal and interest is no longer in doubt.

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

The allowance for loan losses  related to impaired loans that are identified for
evaluation is based on discounted cash flows using the loan's initial  effective
interest  rate or the fair value,  less selling  costs,  of the  collateral  for
collateral  dependent loans. By the time a loan becomes probable of foreclosure,
it has been charged down to fair value, less estimated cost to sell.

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

Loan servicing: The cost of mortgage servicing rights is amortized in proportion
to, and over the period of,  estimated  net  servicing  revenues.  Impairment of
mortgage  servicing  rights is assessed based on the fair value of those rights.
Fair values are estimated using  discounted cash flows based on a current market
interest rate.

Foreclosed  real  estate:  Foreclosed  real  estate,  which is recorded in other
assets,  is comprised of property  acquired through a foreclosure  proceeding or
acceptance of a deed-in-lieu of foreclosure and loans classified as in-substance
foreclosure.  A loan is classified as in-substance foreclosure when the Bank has
taken  possession of the  collateral  regardless of whether  formal  foreclosure
proceedings take place.

Foreclosed  real estate  initially  is recorded at fair value,  net of estimated
selling costs at the date of foreclosure,  establishing a new cost basis.  After
foreclosure,  valuations are periodically performed by management and the assets
are carried at the lower of cost or fair value,  less  estimated  costs to sell.
Revenues and expenses from operations and changes in the valuation allowance are
included in other expenses.

Note 1.  Significant Accounting Policies (Continued)
Premises  and  equipment:  Premises  and  equipment  are  stated  at  cost  less
accumulated  depreciation.  Depreciation  is computed on the  straight-line  and
accelerated depreciation methods over the estimated useful lives of the assets.

Advertising  costs:  The Bank  follows  the  policy  of  charging  the  costs of
advertising  to expense as  incurred.  Advertising  expense  for the years ended
December  31,  1997,  1996  and  1995  was  $316,000,   $313,000  and  $231,000,
respectively.

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

Earnings per share:  The Bank  adopted FASB  Statement  No. 128,  "Earnings  Per
Share", in 1997. Statement No. 128 replaced the calculation of primary and fully
diluted  earnings per share with basic and diluted  earnings  per share.  Unlike
primary  earnings  per share,  basic  earnings  per share  excludes any dilutive
effect of stock options. Diluted earnings per share includes the dilutive effect
of stock options.  The effect of stock options on diluted earnings per share for
the Bank is immaterial and results in the same amount reported as basic earnings
per share for 1997, 1996 and 1995.  Accordingly,  basic and diluted earnings per
share are the same amounts for all periods  presented and are the same amount as
previously reported for 1996 and 1995.

Off-balance sheet financial instruments: In the ordinary course of business, the
Bank has entered into  off-balance  sheet  financial  instruments  consisting of
commitments to extend credit,  letters of credit and  commitments to sell loans.
Such financial  instruments are recorded in the consolidated balance sheets when
they are funded.

Reclassifications:  Certain  items in the 1996 and 1995  consolidated  financial
statements have been reclassified to conform to the 1997 consolidated  financial
statement  presentation  format.  These  reclassifications  had no effect on net
income.


Note 2.  Restrictions On Cash And Due From Bank Balances
The Bank is required to maintain  average reserve balances in vault cash or with
the Federal  Reserve Bank.  The total of those reserve  balances at December 31,
1997 and 1996 were approximately $1,799,000 and $1,407,000, respectively.

The recorded  investment in impaired loans,  not requiring an allowance for loan
losses,  was $431,000 and $108,000 at December 31, 1997 and 1996,  respectively.
The recorded investment in impaired loans requiring an allowance for loan losses
was  $355,000  and  $545,000 at December  31,  1997 and 1996,  respectively.  At
December 31, 1997 and 1996,  the related  allowance  for loan losses  associated
with those  loans was $40,000 and  $188,000,  respectively.  For the years ended
December 31, 1997 and 1996,  the average  recorded  investment in these impaired
loans was  $818,000 and  $310,000,  respectively.  There was no interest  income
recognized on impaired loans in 1997, 1996 and 1995.


Note 5.  Loan Servicing
Effective January 1, 1996, the Bank adopted Financial Accounting Standards Board
Statement  No.  122,  "Accounting  for  Mortgage  Servicing  Rights",  which was
superceded  by Statement  No. 125,  "Accounting  for  Transfers and Servicing of
Financial Assets and Extinguishment of Liabilities,"  effective January 1, 1997.
These Statements  apply to all mortgage  banking  activities in which a mortgage
loan is originated or purchased and then sold or  securitized  with the right to
service the loan retained by the seller. The total cost of the mortgage loans is
allocated between the mortgage  servicing rights and the mortgage loans based on
their relative fair values.  The mortgage  servicing  rights are  capitalized as
assets  and  amortized  over the  period  of  estimated  net  servicing  income.
Additionally,  they are subject to an  impairment  analysis  based on their fair
value in future periods.  Fair values are estimated using  discounted cash flows
based on a current market interest rate.

Note 12.  Employee Benefits
The Bank has a  profit-sharing  plan which,  during 1996, was amended to include
401(k)  provisions.  The Plan is for the benefit of all  employees  who meet the
eligibility  requirements  set forth in the Plan. The amount of contributions to
the Plan, including 401(k) matching  contributions,  is at the discretion of the
Bank's Board of Directors.  The  contributions  charged to expense for the years
ended  December 31, 1997,  1996 and 1995 were  $232,000,  $248,000 and $218,000,
respectively.

Effective July 1, 1997, the Bank established a  non-contributory  Employee Stock
Ownership  Plan  (ESOP) to  acquire  shares of the Bank's  common  stock for the
benefit of all eligible  employees of the Bank.  Subsequent to the establishment
of the Plan,  34,445 shares of the Bank's common stock were  transferred  to the
ESOP  from  the  Bank's  profit-sharing  plan.  Contributions  to the  Plan  are
determined by the Bank's Board of Directors. There were no contributions made to
the Plan  nor  compensation  expense  recorded  by the  Bank for the year  ended
December 31, 1997. In the event a terminated  Plan  participant  desires to sell
their  shares  of the  Bank's  stock,  or for  certain  employees  who  elect to
diversify  their  account  balances,  the Bank may be required  to purchase  the
shares from the participant at their fair market value.

During 1996, the Bank adopted a Stock  Incentive  Plan for certain  officers and
key employees of the Bank. The Plan is  administered  by the Board of Directors.
Under the Bank's  Articles of  Association,  an aggregate  of 210,000  shares of
authorized  but  unissued  common  stock of the Bank were  reserved  for  future
issuance  under  employee  stock option  provisions of the Plan,  employee stock
purchases or similar  employee  benefit plans.  To date,  stock options  granted
under the Plan are non-qualified  and are exercisable over a three-year  period,
commencing  one year  after  the date of grant,  on a  cumulative  basis.  Stock
options  generally  expire ten years after the date of grant. The purchase price
for stock  options  issued  under the Plan must be at least equal to 100% of the
fair market value of the common stock on the date of the grant.

information for the years ended December 31, 1997 and 1996:

Note 12.  Employee Benefits (Continued)
The Bank has adopted the  disclosure-only  provisions  of Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based  Compensation."
Accordingly,  no  compensation  cost has been  recognized for options granted in
1997 and 1996. Had compensation  cost for stock options granted in 1997 and 1996
been  determined  based on the fair value at the grant date  consistent with the
provisions of SFAS No. 123, the Bank's net income and earnings per share for the
years ended  December 31, 1997 and 1996 would have been reduced to the pro forma
amounts indicated below (in thousands, except per share amounts):

          At December 31                     1997          1996
          --------------------------------------------------------
          Net income:
                As reported            $      2,931  $      2,367
                                       ==========================
                Pro forma              $      2,898  $      2,332

          Basic earnings per share:
                As reported            $       1.14  $       0.93

                Pro forma              $       1.13  $       0.92

          Diluted earnings per share:
                As reported            $       1.14  $       0.93
                                       ==========================
                Pro forma              $       1.13  $       0.92
                                       ==========================

The fair  value  of each  option  grant is  estimated  using  the  Black-Scholes
option-pricing model with the following weighted-average assumptions:  risk-free
interest rate of 5.7% for 1997 and 6.2% for 1996; no volatility,  dividend yield
of 0.8%, and an expected life of 5 years for 1997 and 1996. The weighted-average
fair value of options  granted was $ 4.39 per share in 1997 and $ 4.48 per share
in 1996.


Note 13.  Transactions with Executive Officers and Directors
The Bank has had banking  transactions  in the ordinary  course of business with
its executive  officers and  directors  and their related  interests on the same
terms, including interest rates and collateral,  as those prevailing at the time
for comparable  transactions  with others.  At December 31, 1997 and 1996, these
persons were indebted to the Bank for loans totaling  $1,249,000 and $1,322,000,
respectively.  During 1997, $292,000 of new loans were made;  repayments totaled
$365,000.

Note 14.  Financial Instruments With Off-Balance Sheet Risk
The Bank is a party to financial  instruments with off-balance sheet risk in the
normal course of business to meet the financing  needs of its  customers.  These
financial  instruments include  commitments to extend credit,  letters of credit
and commitments to sell loans.  Those instruments  involve,  to varying degrees,
elements  of  credit  risk  and  interest  rate  risk in  excess  of the  amount
recognized in the balance sheets.

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

A  summary  of  the  contractual  amount  of  the  Bank's  financial  instrument
commitments are as follows:

          At December 31
          (In Thousands)                       1997        1996
          ------------------------------------------------------
          Commitments to extend credit      $36,172     $34,377
          Outstanding letters of credit       3,424       2,700
          Commitments to sell loans              --          --

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

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

Commitments  to sell loans are to the  Federal  National  Mortgage  Association.
These commitments are generally met through mortgage  originations in the normal
course of business.


Note 15.  Concentration of Credit Risk
The Bank  grants  commercial,  residential,  and  consumer  loans  to  customers
primarily located in Berks, Chester, and Lancaster Counties in Pennsylvania. The
concentrations  of credit by type of loan are set forth in Note 4.  Although the
Bank has a  diversified  loan  portfolio,  its  debtors'  ability to honor their
contracts is influenced by the region's economy.

Note 16.  Lease Commitments
The Bank rents  facilities and equipment under operating lease  agreements which
expire between 1998 and 2014, and require various  minimum annual  rentals.  The
total  minimum  rental   commitment  at  December  31,  1997  was  approximately
$1,665,000, and is due as follows:

          Year

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

          1998                     $  242
          1999                        175

          2001                        175
          2002                        106
          Later years                 792
                                   ------
          Total                    $1,665
                                   ======

The total rental expense included in the  consolidated  statements of income for
the years ended  December 31,  1997,  1996 and 1995 was  $365,000,  $379,000 and
$362,000, respectively.


Note 17.  Regulatory Matters and Stockholders' Equity
The Bank is subject to various regulatory capital  requirements  administered by
the federal banking agencies.  Failure to meet minimum capital  requirements can
initiate  certain  mandatory and possibly  additional  discretionary-actions  by
regulators  that,  if  undertaken,  could have a direct  material  effect on the
Bank's  financial   statements.   Under  capital  adequacy  guidelines  and  the
regulatory  framework for prompt corrective  action, the Bank must meet specific
capital  guidelines  that involve  quantitative  measures of the Bank's  assets,
liabilities and certain  off-balance  sheet items as calculated under regulatory
accounting  practices.  The Bank's capital amounts and  classification  are also
subject to  qualitative  judgments  by the  regulators  about  components,  risk
weightings and other factors.

Quantitative  measures  established  by  regulation to ensure  capital  adequacy
require the Bank to  maintain  minimum  amounts and ratios (set forth  below) of
total  and Tier 1 capital  (as  defined  in the  regulations)  to  risk-weighted
assets,  and of Tier I capital to average  assets.  Management  believes,  as of
December  31, 1997,  that the Bank meets all capital  adequacy  requirements  to
which it is subject.

Banking laws and  regulations  limit the amount of  dividends  that may be paid.
Under  current  banking  laws,  the  Bank  would  be  limited  to  approximately
$4,347,000  of dividends in 1998 plus an  additional  amount equal to the Bank's
net  profit  for  1998,  up to the date of any  such  dividend  declaration.  In
November  1997,  the Bank  declared a $.043 per share  regular cash  dividend to
stockholders  of record on December 15,  1997,  payable  January 1, 1998,  and a
$.048 per share  special cash dividend to  stockholders  of record on January 2,
1998, payable January 16, 1998.

In April 1997,  the Bank changed its capital  structure to 4,000,000  authorized
shares of common stock,  with a par value of $1.25 per share.  Also,  the Bank's
Board  of  Directors  declared  a  2-for-1  stock  split  in the form of a stock
dividend distributed May 16, 1997 to shareholders of record on April 25, 1997.

In February  1998,  the Bank declared a 5% stock  dividend with a record date of
April 3, 1998,  payable April 10, 1998. All per share amounts and average shares
outstanding in the  accompanying  statements  were adjusted to give  retroactive
effect to the aforementioned stock changes.

Note 20.  Fair Value of Financial Instruments
Management  uses its best  judgment in  estimating  the fair value of the Bank's
financial instruments;  however, there are inherent weaknesses in any estimation
technique.  Therefore,  for  substantially all financial  instruments,  the fair
value estimates  herein are not  necessarily  indicative of the amounts the Bank
could have realized in a sales transaction on the dates indicated. The estimated
fair value amounts have been measured as of their respective year ends, and have
not been  re-evaluated or updated for purposes of these  consolidated  financial
statements  subsequent to those  respective  dates.  As such, the estimated fair
values of these  financial  instruments  subsequent to the respective  reporting
dates may be different than the amounts reported at each year end.

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

Cash and cash  equivalents:  The carrying  amounts reported in the balance sheet
for cash and short-term instruments approximate those assets' fair values.

Securities:  Fair values for securities are based on quoted market prices, where
available.  If quoted market prices are not available,  fair values are based on
quoted market prices of comparable securities.

Loans receivable:  For variable-rate  loans that reprice  frequently and with no
significant change in credit risk, fair values are based on carrying values. The
fair  values for fixed  rate  loans are  estimated  using  discounted  cash flow
analyses,  using interest rates  currently  being offered for loans with similar
terms to borrowers of similar credit quality.

Accrued interest receivable: The carrying amounts of accrued interest receivable
approximate their fair value.

Deposit  liabilities:  The fair value of demand  deposits,  savings accounts and
certain money market  accounts is the amount  payable on demand at the reporting
date. The carrying  amounts for  variable-rate  fixed-term money market accounts
and  certificates  of deposits  approximate  their fair values at the  reporting
date. The fair value of fixed-rate certificates of deposit are estimated using a
discounted  cash flow  calculation  that applies  interest rates currently being
offered for deposits of similar remaining maturities.

Securities  sold  under  agreements  to  repurchase:  The  carrying  amounts  of
securities sold under agreements to repurchase approximate their fair value.

Borrowed funds: The fair values of the Bank's borrowed funds are estimated using
discounted cash flow analyses, based on the Bank's current incremental borrowing
rates for similar types of borrowing  arrangements.  The carrying amounts of the
U.S. Treasury tax and loan note approximate its fair value.

Note 20.  Fair Value of Financial Instruments (Continued)
Accrued  interest  payable:  The carrying  amounts of accrued  interest  payable
approximate their fair value.

Off-balance  sheet  instruments:  The fair values of the Bank's  commitments  to
extend credit and  outstanding  letters of credit are  estimated  using the fees
currently  charged to enter into  similar  agreements,  taking into  account the
remaining terms of the agreements and the counterparties' credit standing.

The estimated fair value of the Bank's financial instruments were as follows:

ELVERSON NATIONAL BANK AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)


Note 1.  Basis of Presentation
The unaudited consolidated financial statements include the accounts of Elverson
National Bank and its  wholly-owned  subsidiaries  (the Bank).  All intercompany
accounts and transactions have been eliminated in consolidation.

The accompanying  unaudited consolidated financial statements have been prepared
in  conformity  with  generally  accepted  accounting   principles  for  interim
financial information.  Accordingly,  they do not include all of the information
and footnotes required by generally accepted accounting  principles for complete
financial statements.

In preparing the financial statements,  management is required to make estimates
and assumptions that affect the reported amounts of assets and liabilities as of
the date of the balance  sheet and revenues and expenses for the period.  Actual
results could differ from those estimates.  The financial statements reflect, in
the  opinion  of  management,   all  normal,  recurring  adjustments  considered
necessary to present  fairly the financial  position of the Bank.  The operating
results for the six months ended June 30, 1998 are not necessarily indicative of
the results  that may be expected  for the year ending  December 31, 1998 or any
other period.


Note 2.  Earnings Per Share
During 1997, the Financial  Accounting Standards Board issued Statement No. 128,
"Earnings Per Share".  This  statement  replaced the  calculation of primary and
fully  diluted  earnings  per share with basic and diluted  earnings  per share.
Unlike  primary  earnings  per share,  basic  earnings  per share  excludes  any
dilutive effects of stock options, warrants and convertible securities.  Diluted
earnings  per share is very similar to the  previously  reported  fully  diluted
earnings per share.

The following table sets forth the  computations  of basic and diluted  earnings
per share (in thousands, except per share data):

Note 4.  Stock Dividend
In February  1998,  the Bank declared a 5% stock  dividend with a record date of
April 3, 1998, payable April 10, 1998. This stock dividend was given retroactive
recognition in the December 31, 1997 consolidated financial statements.  All per

requires all  derivatives to be recorded on the balance sheet at fair values and
establishes  "special  accounts" for three different  types of hedges.  This new

not be unreasonably withheld) shall be the directors of the Surviving Bank, each
to hold office until his or her  successor is elected and qualified or otherwise
in accordance with applicable law, the articles of association and bylaws of the
Surviving Bank, provided,  however,  that with respect to the ENB Nominees,  NPB
and the Bank shall take all steps  necessary  to insure  that such  persons,  or
their  successors,  are  re-elected to the Bank's Board of Directors for each of
the five years  following  the  Effective  Date if such persons are in office as
directors  of NPB on the annual  election  dates.  In the event that  either ENB
Nominee, or any successor, resigns, dies or is otherwise removed from the Bank's
Board of  Directors  prior to the end of such five  year  period,  the  Elverson
Continuing  Directors,  by a plurality vote,  shall have the right to select the
successor to such ENB Nominee,  subject to approval of such person by NPB (which
approval will not be  unreasonably  withheld).  On and after the Effective Date,
the officers of Bank duly elected and holding  office  immediately  prior to the
Effective Date shall be the officers of the Surviving  Bank, each to hold office
until his or her  successor is elected and  qualified or otherwise in accordance
with  applicable  law, the articles of  association  and bylaws of the Surviving
Bank.

         (f) Conversion of Shares.

                  (i) Bank  Capital  Stock.  Each share of the capital  stock of
Bank issued and  outstanding  immediately  prior to the Effective Date shall, on
the Effective Date,  continue to be issued and outstanding as a share of capital
stock of the Surviving Bank.

                  (ii) ENB Common Stock.

                           (A) Conversion. Subject to subsections (f)(ii)(B) and
(f)(ii)(C)  below with respect to treasury stock and fractional  shares,  and to
subsection  (f)(ii)(F)  below with  respect to  dissenting  shares of ENB Common
Stock,  each share of ENB Common Stock issued and outstanding  immediately prior
to the Effective Date, shall, on the Effective Date, by reason of the Merger and
without any action on the part of the holder  thereof,  cease to be  outstanding
and be converted into the right to receive, subject to adjustment as provided in
subsection


                                      II-5
<PAGE>

(f)(ii)(E) and subsection (i) below,  1.175 shares of NPB Common Stock including
the associated  rights to purchase  securities  pursuant to the Rights Agreement
[the number 1.175 shall be adjusted to 1.46875 upon  completion of the NPB Stock
Split].

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

                           (C) Fractional  Shares.  No fractional  shares of NPB
Common Stock and no scrip or certificates therefor shall be issued in connection
with the Merger.  Any former  holder of ENB Common Stock who would  otherwise be
entitled to receive a fraction of a share of NPB Common Stock shall receive,  in
lieu thereof,  cash in an amount equal to such fraction of a share multiplied by
NPB Market Value (as defined in subsection (f)(ii)(D) below).

                           (D) Market Value of NPB Common Stock. For purposes of
this  Agreement,  the market  value of a share of NPB Common  Stock ("NPB Market
Value")  shall be deemed to be the average of the closing  sale price of a share
of NPB Common  Stock,  as reported on The Nasdaq Stock Market,  National  Market
tier, as published in the Wall Street Journal,  for the twenty trading days (the
"Determination  Period") ending on the Determination  Date.  Notwithstanding any
other provision of this Agreement,  however,  the Determination Period shall not
begin prior to the ten days after the date of this Agreement.

                           (E) Exchange Ratio Adjustment. If NPB Market Value is
less than  $30.38 per share,  then the  exchange  ratio set forth in  subsection
(f)(ii)(A) above shall be adjusted to 1.2 shares of NPB Common Stock in exchange
for each share of ENB Common Stock [the dollar  amount $30.38 and the number 1.2
shall be adjusted to $24.30 and 1.5,  respectively,  upon  completion of the NPB
Stock Split], subject to the provisions of Section 6.01(c) below.

                           (F) Dissenting ENB Shareholders. If there are holders
of ENB Common  Stock who dissent  from the Merger and  exercise  and perfect the
right to obtain  valuation  of and payment  for their  shares  ("Dissenting  ENB
Shares")  pursuant  to  Section  215a(b)  of the  National  Bank Act (12  U.S.C.
ss.215a(b)), the following provisions will govern payments to be made in respect
of Dissenting ENB Shares:

                                (1) All  payments in respect of  Dissenting  ENB
Shares, if any, will be made by NPB or the Surviving Bank, as they shall agree.

                                (2)  Dissenting  ENB  Shares,  if  any,  will be
deemed to have been retired and cancelled  immediately prior to the Merger, with
the  effect  that no  conversion  thereof  will  occur  pursuant  to  subsection
(f)(ii)(A)  above  unless and until such holder  shall have failed to perfect or
effectively  shall have  withdrawn  or lost his right to  appraisal  and payment
under such section.  If any such holder of ENB Common Stock shall have so failed
to perfect or effectively  shall have withdrawn or lost such right,  each of his
shares of ENB Common  Stock  shall  thereupon  be deemed to have been  converted
into, on the Effective Date, the right to receive shares of NPB Common Stock and
cash in lieu of fractional shares as set forth in Section 1.02(f)(ii)(A) and (C)
above.

         (g)  Stock Options.

                  (i) On the  Effective  Date,  each option (an "ENB Option") to
purchase one or more shares of ENB Common Stock issued by ENB and outstanding on
the Effective  Date,  whether or not such option is exercisable on the Effective
Date,  shall, by virtue of the Merger,  cease to be outstanding and be converted
into an option to  purchase  the number of shares of NPB Common  Stock which the
optionholder  would have been  entitled to receive in the Merger had such option
been exercised in full  immediately  prior to the Effective Date, at an exercise
price per share of NPB Common Stock equal to the per share exercise price of the
option to purchase ENB Common stock  divided by the Exchange  Ratio,  and having
other terms and conditions identical to those of the option exchanged (including
forfeiture,   acceleration  and  expiration  date  provisions).  The  adjustment
provided herein with respect to any options which are "incentive stock options",
as defined in Section 422 of the IRC, shall be and is intended to be effected in
a manner which is consistent with Section 424(a) of the IRC. As a result of this
Agreement and as


                                      II-6
<PAGE>

provided  in  the  ENB  1996  Stock  Incentive  Plan,  all  options  issued  and
outstanding  under the ENB 1996 Stock  Incentive  Plan shall  become 100 percent
vested and immediately exercisable.

                  (ii) As soon as  practicable  after the  Effective  Date,  NPB
shall deliver to the holders of ENB Options  appropriate  notices  setting forth
such holders' rights pursuant to the ENB Stock Option Plans  (including that, by
virtue of the Merger and  pursuant to the terms of the ENB Stock  Option  Plans,
the ENB  Stock  Options  have  become  fully  vested  and  exercisable)  and the
agreements  evidencing  the grants of such ENB Stock Options  shall  continue in
effect on the same terms and conditions (subject to the adjustments  required by
this Section  1.02(g) after giving effect to the Merger and the terms of the ENB
Stock  Option  Plans).  NPB shall  comply with the terms of the ENB Stock Option
Plans and shall take such reasonable  steps as are necessary or required by, and
subject to the provisions of, such ENB Stock Option Plans, to have the ENB Stock
Options,  if any,  which  qualified as "incentive  stock  options"  prior to the
Effective  Date,  continue to qualify as  "incentive  stock  options"  after the
Effective Date.

                  (iii) NPB shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of NPB Common Stock for delivery upon
exercise of ENB Stock Options in accordance with this Agreement.  Promptly after
the Effective Date, NPB shall file a registration  statement on Form S-3 or Form
S-8, as the case may be (or any successor other appropriate forms), with respect
to the  shares  of NPB  Common  Stock  subject  to such  options  and  shall use
commercially   reasonable   efforts  to  maintain  the   effectiveness  of  such
registration  statement or  registration  statements  (and  maintain the current
status of the prospectus or prospectuses  contained thereon) for so long as such
options remain outstanding. With respect to those individuals who, subsequent to
the Merger, will be subject to the reporting requirements under Section 16(a) of
the Exchange Act, where  applicable,  NPB shall  administer the ENB Stock Option
Plans  in a  manner  consistent  with  the  exemptions  provided  by Rule  16b-3
promulgated under the Exchange Act.

         (h) Surrender and Exchange of ENB Stock Certificates.

                  (i) Each holder of shares of ENB Common  Stock who  surrenders
to NPB the certificate or certificates  representing  such shares (each, an "ENB
Certificate")  shall be  entitled to receive in  exchange  therefor,  as soon as
practicable  after the  Effective  Date, a  certificate  for the number of whole
shares of NPB Common Stock into which such  holder's  shares of ENB Common Stock
have been converted by the Merger, together with a check for cash in lieu of any
fractional  share in accordance  with subsection  (f)(ii)(C)  above (the "Merger
Consideration").

                  (ii) Each  certificate for shares of NPB Common Stock (each, a
"NPB  Certificate")  issued  in  exchange  for  ENB  Certificates   pursuant  to
subsection  (h)(i)  above shall be dated the  Effective  Date and be entitled to
dividends and all other rights and privileges pertaining to such shares of stock
from the Effective Date. Until surrendered, each ENB Certificate shall, from and
after the Effective Date,  evidence solely the right to receive NPB Certificates
pursuant  to  subsection  (h)(i)  above  and a  check  for  cash  in lieu of any
fractional  share in accordance  with  subsection  (f)(ii)(C)  above.  If an ENB
Certificate  is exchanged on a date  following  one or more record dates for the
payment of dividends or any other  distribution  on shares of NPB Common  Stock,
NPB shall pay to such shareholder  cash in an amount equal to dividends  payable
on such shares of NPB Common Stock and pay or deliver any other  distribution to
which such  shareholder  is entitled.  No interest shall accrue or be payable in
respect of  dividends or any other  distribution  otherwise  payable  under this
subsection  (h)(ii) upon  surrender  of ENB  Certificates.  Notwithstanding  the
foregoing, no party hereto shall be liable to any holder of ENB 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 ENB
Certificates  are  surrendered to NPB for exchange,  NPB shall have the right to
withhold dividends or any other  distributions on the shares of NPB Common Stock
issuable to such shareholder.

                  (iii) Each ENB  Certificate  delivered for exchange under this
subsection  (h) must be endorsed in blank by the  registered  holder  thereof or
accompanied by a power of attorney to transfer such shares  endorsed in blank by
such holder.

                  (iv) Upon the Effective Date, the stock transfer books for ENB
Common  Stock will be closed and no further  transfers  of ENB Common Stock will
thereafter be made or recognized.  All ENB Certificates  surrendered pursuant to
this subsection (h) will be cancelled.



                                      II-7
<PAGE>

                  (v) As soon as  reasonably  practicable  after  the  Effective
Date, NPB shall cause Bank or another  institutional  entity selected by NPB, as
the  exchange  agent (the  "Exchange  Agent")  to mail to each  holder of an ENB
Certificate (i) a letter of transmittal  which shall specify that delivery shall
be effected, and risk of loss and title to the ENB Certificates shall pass, only
upon delivery of the ENB  Certificates to the Exchange  Agent,  and which letter
shall be in customary form and have such other  provisions as NPB reasonably may
specify  and  (ii)   instructions  for  effecting  the  surrender  of  such  ENB
Certificates in exchange for the applicable Merger Consideration. Upon surrender
of an ENB  Certificate  to the  Exchange  Agent  together  with  such  letter of
transmittal,  duly executed and completed in  accordance  with the  instructions
thereto,  and such other documents as reasonably may be required by the Exchange
Agent,  the  holder of such ENB  Certificate  shall be  entitled  to  receive in
exchange  therefor (A) one or more shares of NPB Common Stock  representing,  in
the  aggregate,  the whole  number of shares  that such  holder has the right to
receive pursuant to Section 1.02(f) (after taking into account all shares of ENB
Common  Stock then held by such  holder) and (B) a check in the amount  equal to
the cash that such holder has the right to receive pursuant to the provisions of
this Section 1.02, including cash in lieu of any fractional shares and dividends
and other  distributions  pursuant  to  Section  1.02(h)(ii).  In the event of a
transfer  of  ownership  of ENB  Common  Stock  which is not  registered  in the
transfer  records  of  ENB,  one or more  NPB  Certificates  evidencing,  in the
aggregate,  the  proper  number of shares of NPB  Common  Stock,  a check in the
proper  amount of cash in lieu of any  fractional  shares and any  dividends  or
other  distributions  to which  such  holder is  entitled  pursuant  to  Section
1.02(h)(ii),  may be issued  with  respect  to such ENB  Common  Stock to such a
transferee if the ENB Certificate  representing  such shares of ENB Common Stock
is presented to the Exchange  Agent,  accompanied  by all documents  required to
evidence and effect such  transfer  and to evidence  that any  applicable  stock
transfer taxes have been paid.

         (i) Anti-Dilution  Provisions.  If, in addition to the NPB Stock Split,
NPB shall, at any time before the Effective Date, (A) issue a dividend in shares
of NPB Common Stock, (B) combine the outstanding shares of NPB Common Stock into
a smaller number of shares, (C) split or subdivide the outstanding shares of NPB
Common Stock,  or (D)  reclassify  the shares of NPB Common Stock,  then, in any
such  event,  the number of shares of NPB Common  Stock to be  delivered  to ENB
shareholders  who are entitled to receive shares of NPB Common Stock in exchange
for shares of ENB Common  Stock shall be  adjusted so that each ENB  shareholder
shall be entitled to receive  such number of shares of NPB Common  Stock as such
shareholder  would  have been  entitled  to receive  if the  Effective  Date had
occurred prior to the happening of such event. (By way of  illustration,  if NPB
shall declare a stock dividend of 7% payable with respect to a record date on or
prior to the  Effective  Date,  the  exchange  ratio  set  forth  in  subsection
(f)(ii)(A) hereof shall be adjusted upward by 7%.)


                                   ARTICLE II

                      REPRESENTATIONS AND WARRANTIES OF ENB

registration  or  qualification  necessary,  except  where the  failure to be so
licensed,  registered or qualified will not have a Material Adverse Effect,  and
all such licenses, registrations and qualifications are in full force and effect
in all material respects.

Regulatory  Authorities  referred to in Section 3.04 hereof and compliance  with

         2.05  Financial Statements.

         (a)  ENB  has  delivered  to  NPB  the  ENB  Financials,  except  those
pertaining to quarterly  periods  commencing  after June 30, 1998, which it will
deliver  to NPB  within 45 days  after the end of the  respective  quarter.  The
delivered  ENB  Financials  fairly  present,  in  all  material  respects,   the
consolidated financial position,  results of operations and cash flows of ENB as
of and for the periods ended on the dates thereof,  in accordance with generally
accepted  accounting  principles  consistently  applied,  except in each case as
noted therein and, in the case of interim period financial  statements,  subject
to normal year-end adjustments and footnotes thereto.

         (b) To the  knowledge  of ENB,  ENB did not  have  any  liabilities  or
obligations of any nature, whether absolute,  accrued,  contingent or otherwise,
which are not fully reflected or reserved against in the balance sheets included
in the ENB  Financials at the date of such balance  sheets which would have been
required  to  be  reflected  therein  in  accordance  with  generally   accepted
accounting  principles  consistently applied or disclosed in a footnote thereto,
except for  liabilities  and  obligations  which were  incurred in the  ordinary
course of business consistent with past practice, and except for liabilities and
obligations which are within the subject matter of a specific representation and
warranty herein or which otherwise have not had a Material Adverse Effect.

         2.06 No  Material  Adverse  Change.  ENB has not  suffered  any adverse
change in its assets,  business,  financial  condition or results of  operations
since June 30, 1998 which  change has had a Material  Adverse  Effect,  it being
understood  that the expenses  incurred by ENB in connection with this Agreement
and the Merger,  including,  without  limitation,  the  engagement  of legal and
financial advisors, shall not constitute a Material Adverse Effect.

         2.07  Taxes.

         (a) ENB has filed,  and will file,  in correct form all federal,  state
and local tax returns required to be filed by or with respect to ENB on or prior
to the  Closing  Date  except  to the  extent  that any  failure  to file or any
inaccuracies  would  not,  individually  or in the  aggregate,  have a  Material
Adverse Effect,  and has paid or will pay, or made or will make,  provisions for
the  payment  of all  federal,  state  and local  taxes  which are shown on such
returns to be due for the periods  covered  thereby  from ENB to any  applicable
taxing authority, on or prior to the Closing Date other than taxes which (i) are
not delinquent or are being contested in good faith,  (ii) have not been finally
determined,  or (iii) the  failure  to pay  would  not,  individually  or in the
aggregate, have a Material Adverse Effect.

         (b) To the knowledge of ENB, there are no material disputes pending, or
claims asserted in writing,  for taxes or assessments upon ENB, nor has ENB been
requested  in writing to give any  currently  effective  waivers  extending  the
statutory period of limitation applicable to any federal, state, county or local
income tax return for any period.

         (c) Proper and  accurate  amounts  have been  withheld  by ENB from its
employees for all prior periods in compliance in all material  respects with the
tax withholding  provisions of applicable federal,  state and local laws, except
where  failure  to do so is not  reasonably  likely to have a  Material  Adverse
Effect.

         2.08  Contracts.

         (a) Except as described in ENB Disclosure Schedule 2.08(a) or 2.12, ENB
is not a party to or subject  to:  (i) any  employment,  consulting,  severance,
"change-in-control"  or termination  contract or  arrangement  with any officer,
director,  employee,  independent contractor,  agent or other person, except for
"at will"  arrangements;  (ii) any plan,  arrangement or contract  providing for
bonuses, pensions,  options, deferred compensation,  retirement payments, profit
sharing or similar  arrangements  for or with any officer,  director,  employee,
independent  contractor,  agent or other person; (iii) any collective bargaining
agreement  with any labor union relating to employees of ENB; (iv) except in the
ordinary course of business,  any material  instrument  evidencing or related to
indebtedness  for borrowed  money,  whether  directly or  indirectly,  by way of
purchase  money  obligation,  conditional  sale,  lease  purchase,  guaranty  or
otherwise,  in  respect  of which  ENB is an  obligor  to any  person,  or which
contains financial

                                     II-10
<PAGE>

covenants  or other  restrictions,  other than those  relating to the payment of
principal  and  interest  when due,  which would be  applicable  on or after the
Closing Date; (v) any contract,  other than this  Agreement,  which restricts or
prohibits ENB from engaging in any type of business permissible under applicable
law;  or (vi)  except in the  ordinary  course of  business,  any lease for real
property.

         (b) All the contracts,  plans,  arrangements and instruments  listed in
ENB Disclosure Schedule 2.08(a) are in full force and effect on the date hereof,

and no party to any such contract, plan, arrangement or instrument will have the

Schedule 2.08(a) or 2.12, no plan, employment  agreement,  termination agreement

upon the  occurrence  of a change in  ownership  or  control  or merger or other
acquisition  of ENB; or (iii)  requires  ENB to provide a benefit in the form of

contained in the ENB Financials or acquired  subsequent  thereto  (except to the
extent that such  securities  are held in any  fiduciary or agency  capacity and
except to the extent that such assets and  properties  have been disposed of for
fair value,  in the  ordinary  course of business,  or have been  disposed of as
obsolete  since the date of such balance  sheets),  subject to no  encumbrances,
liens, mortgages,  security interests or pledges, except (i) statutory liens for
amounts not yet  delinquent  or which are being  contested  in good faith,  (ii)
liens for current  taxes not yet due and payable,  (iii) such  imperfections  of
title,  easements  and  encumbrances,  if any, as are not material in character,

consideration in the ordinary course of business. ENB has the right under leases
of material  properties used by ENB in the conduct of its business to occupy and
use all such properties in all material respects as presently  occupied and used
by it.

         (b) With respect to all agreements  pursuant to which ENB has purchased
securities subject to an agreement to resell, if any, ENB has a valid, perfected
first lien or security  interest in the securities or other collateral  securing
the repurchase agreement, and the value of such collateral equals or exceeds the
amount of the debt  secured  thereby,  except to the extent  that any failure to
obtain such a lien or maintain such collateral would not, individually or in the
aggregate, have a Material Adverse Effect.

         (c) ENB currently  maintains  insurance in amounts considered by ENB to
be reasonable  for its  operations,  and such  insurance is similar in scope and
coverage  in all  material  respects  to that  maintained  by  other  businesses
similarly situated.  ENB has not received notice from any insurance carrier that
(i) such insurance will be cancelled or that coverage thereunder will be reduced
or  eliminated,  or (ii) premium  costs with respect to such  insurance  will be
substantially  increased  except to the  extent  such  cancellation,  reduction,
elimination or increase would not have a Material Adverse Effect.

         (d)  ENB  currently  maintains  such  fidelity  bonds  and  errors  and
omissions  insurance as may be customary or required  under  applicable  laws or
regulations.

         2.10  Legal  Proceedings.  ENB is not a party to any,  and there are no

         (a) ENB holds all  licenses,  franchises,  permits  and  authorizations
necessary for the lawful  conduct of its businesses  under,  and has complied in
all  material  respects  with,  applicable  laws,  statutes,  orders,  rules  or
regulations  of any Regulatory  Authority  relating to it, other than where such
failure to hold or such noncompliance will neither result in a limitation in any
material  respect on the conduct of its businesses nor otherwise have a Material
Adverse Effect.

         (b) ENB has filed all reports,  registrations and statements,  together
with any  amendments  required  to be made  with  respect  thereto,  that it was

paid all fees and  assessments due and payable in connection  therewith,  except
where the failure to file such report,  registration or statement or to pay such
fees and assessments,  either individually or in the aggregate,  will not have a
Material Adverse Effect.

         (c) No Regulatory  Authority has  initiated any  proceeding  or, to the
knowledge of ENB,  investigation  into the business or operations of ENB, except
where any such proceedings or  investigations  will not,  individually or in the
aggregate, have a Material Adverse Effect, or such proceedings or investigations
have been terminated or otherwise resolved.

         (d) ENB has not received any  notification  or  communication  from any
Regulatory  Authority  (i)  asserting  that ENB has not complied with any of the
statutes,  regulations or ordinances which such Regulatory  Authority  enforces,
unless such  assertion has been waived,  withdrawn or otherwise  resolved;  (ii)

operations of ENB; or (iv) directing,  restricting or limiting, or purporting to
direct, restrict or limit, in any manner the operations of ENB (any such notice,

a Material Adverse Effect.  ENB has not received,  consented to, or entered into
any Regulatory Agreement which would have,  individually or in the aggregate,  a
Material Adverse Effect.

         (e)  To  the  knowledge  of  ENB,  there  is no  unresolved  violation,
criticism,  or  exception  by  any  Regulatory  Authority  with  respect  to any
Regulatory  Agreement  which if resolved in a manner adverse to ENB would have a
Material Adverse Effect.

         (f) There is no injunction,  order, judgment or decree imposed upon ENB
or the assets of ENB which has had, or, to the  knowledge  of ENB,  will have, a

Neither ENB nor any pension  plan  (within  the meaning of ERISA  Section  3(2))

with respect to any such pension plan. ENB has not incurred any liability  under
ERISA Section 4201 for a complete or partial  withdrawal  from a  multi-employer
plan. Each ENB Benefit Plan has been  maintained,  operated and  administered in
compliance  in all respects  with its terms and related  documents or agreements
and the applicable  provisions of all laws,  including ERISA and the IRC, except
where any such  non-compliance  would not have a Material Adverse Effect.  As of
the date hereof,  ENB is not aware of any existing or contemplated  audit of its
employee benefit plans by the Internal Revenue Service or the U.S. Department of
Labor.

         (b) With  respect to any  services  which ENB may provide as a sponsor,

knowledge of ENB,  neither ENB, any ENB  Subsidiary,  nor any property  owned or
operated by ENB or any ENB  Subsidiary  has been or is in violation of or liable

individually  or in the  aggregate,  would not have a Material  Adverse  Effect.

notices,  demand  letters  or  requests  for  information  from  any  Regulatory

with  respect to any  property  owned or operated  by ENB or any ENB  Subsidiary
under any  Environmental  Law,  except as to any such  actions or other  matters
which will not result in a Material Adverse Effect.

         (b) Except as set forth on ENB  Disclosure  Schedule 2.14, no property,

the  National  Priority  List  under the  Comprehensive  Environmental  Response
Compensation  and  Liability  Act of  1980,  as  amended,  on the  Comprehensive
Environmental  Response Compensation and Liabilities  Information System, or any
similar  state  list,  or  which  is the  subject  of  federal,  state  or local
enforcement actions or other investigations which may lead to claims against ENB
or any ENB Subsidiary for response costs, remedial work,  investigation,  damage
to natural resources or for personal injury or property damage claim, including,

                                     II-13

         2.16 CRA Compliance.  ENB is in material compliance with the applicable
provisions of the CRA, and, as of the date hereof, ENB has received a CRA rating
of  "satisfactory"  or better from the OCC. ENB knows of no fact or circumstance
or set of facts or  circumstances  which  would cause ENB to fail to comply with
such provisions in a manner which would have a Material Adverse Effect.

         2.17  Allowance  for Loan Losses.  The allowance for loan losses shown,
and to be shown,  on the balance  sheets  contained in the ENB  Financials  have
been, and will be, established in accordance with generally accepted  accounting
principles and all applicable regulatory criteria.

         2.18  Information to be Supplied.  The information  supplied by ENB for
inclusion  in  the  Registration   Statement   (including  the  Prospectus/Proxy
Statement)  will  not,  at the  time  the  Registration  Statement  is  declared
effective   pursuant   to  the   Securities   Act,   and  as  of  the  date  the
Prospectus/Proxy  Statement is mailed to  shareholders  of ENB and NPB and up to
and including the dates of the meetings of  shareholders of ENB and NPB to which
such  Prospectus/Proxy  Statement  relates,  contain any untrue  statement  of a
material fact or omit to state any material fact  necessary in order to make the
statements made therein,  in the light of the  circumstances  in which they were
made,  not  misleading.  The  information  supplied by ENB for  inclusion in the
Applications  will,  at the time such  documents  are filed with any  Regulatory
Authority and up to and including the dates of any required regulatory approvals
or  consents,  as it may be amended by  subsequent  filings,  be accurate in all
material respects.

         2.19 Related Party Transactions. Except as previously disclosed to NPB,
disclosed on ENB  Disclosure  Schedule 2.19, or as is disclosed in the footnotes
to the  ENB  Financials,  as of the  date  hereof,  ENB  is not a  party  to any
transaction  (including  any loan or other credit  accommodation  but  excluding
deposits in the ordinary  course of business) with any Affiliate of ENB; and all
such transactions were made on substantially the same terms,  including interest
rates  and  collateral,   as  those   prevailing  at  the  time  for  comparable
transactions  with other  persons (as defined in Section  13(d) of the  Exchange
Act,  and  the  rules  and  regulations  thereunder),  except  with  respect  to
variations in such terms as would not, individually or in the aggregate,  have a
Material Adverse Effect. Except as set forth in ENB Disclosure Schedule 2.19, as
of the date hereof,  no loan or credit  accommodation to any Affiliate of ENB is
presently in default or, during the three-year  period prior to the date of this
Agreement,  has been in material default or has been  restructured,  modified or
extended in any manner  which  would have a Material  Adverse  Effect.  To ENB's
knowledge,  as of the date hereof,  principal  and interest  with respect to any
such loan or other credit accommodation will be paid when due and the loan grade
classification accorded such loan or credit accommodation is appropriate.

         2.20 Loans.  Each loan  reflected as an asset in the ENB Financials (a)
is evidenced by notes,  agreements or other evidences of indebtedness  which are
true,  genuine and correct and (b) to the extent  secured,  has been  secured by
valid liens and security interests which have been perfected, in each case other
than loans as to which the failure to satisfy the foregoing  standards would not
have a Material Adverse Effect on ENB.

         2.21 Accounting for the Merger; Reorganization.  As of the date hereof,
ENB does not have any reason to believe that the Merger will fail to qualify (i)
for  "pooling  of  interests"  accounting  treatment  under  generally  accepted
accounting  principles,  or (ii) as a reorganization under Section 368(a) of the
IRC.

         2.22 Fairness Opinion.  ENB has received a written opinion from Berwind
to the effect that, as of the date hereof,  the  consideration to be received by
shareholders  of ENB pursuant to this Agreement is fair,  from a financial point
of view, to such shareholders.

         2.23  Year  2000  Compliance.  ENB is in  compliance  in  all  material
respects with the Year 2000 compliance  time-frames  established in OCC Advisory
Letter  97-6,  the  safety  and  soundness  and other  guidelines  for Year 2000
business  risk issued from time to time by the  Federal  Financial  Institutions
Examination  Council,  and the guidance  contained in OCC Advisory Letters 97-10
(December 17, 1997) and 98-1  (January 20, 1998),  except to the extent that the
failure so to comply would not have a Material Adverse Effect.

         (b) To the  knowledge  of NPB,  NPB did not  have  any  liabilities  or
obligations of any nature, whether absolute,  accrued,  contingent or otherwise,
which are not fully reflected or reserved against in the balance sheets included

required  to  be  reflected  therein  in  accordance  with  generally   accepted
accounting principles consistently applied or disclosed in a footnote

ordinary  course of  business  consistent  with past  practice,  and  except for
liabilities  and  obligations  which are within the subject matter of a specific
representation  and warranty  herein or which  otherwise have not had a Material
Adverse Effect.

         3.06 No  Material  Adverse  Change.  NPB has not  suffered  any adverse
change in its assets,  business,  financial  condition or results of  operations
since June 30, 1998 which change has had a Material Adverse Effect.

         3.07  Taxes.

         (a) NPB has filed,  and will file,  in correct form all federal,  state
and local tax returns required to be filed by or with respect to NPB on or prior
to the  Closing  Date  except  to the  extent  that any  failure  to file or any
inaccuracies  would  not,  individually  or in the  aggregate,  have a  Material
Adverse Effect,  and has paid or will pay, or made or will make,  provisions for
the  payment  of all  federal,  state  and local  taxes  which are shown on such
returns to be due for the periods  covered  thereby  from NPB to any  applicable
taxing authority, on or prior to the Closing Date other than taxes which (i) are
not delinquent or are being contested in good faith,  (ii) have not been finally
determined,  or (iii) the  failure  to pay  would  not,  individually  or in the
aggregate, have a Material Adverse Effect.

         (b) To the knowledge of NPB, there are no material disputes pending, or
claims asserted in writing,  for taxes or assessments upon NPB, nor has NPB been
requested  in writing to give any  currently  effective  waivers  extending  the
statutory period of limitation applicable to any federal, state, county or local
income tax return for any period.

         (c) Proper and  accurate  amounts  have been  withheld  by NPB from its
employees for all prior periods in compliance in all material  respects with the
tax withholding  provisions of applicable federal,  state and local laws, except

Effect.

         (a) NPB has,  and will  have as to  property  acquired  after  the date

including  securities,  assets and  properties  reflected in the balance  sheets
contained in the NPB Financials or acquired  subsequent  thereto  (except to the
extent that such  securities  are held in any  fiduciary or agency  capacity and
except to the extent that such assets and  properties  have been disposed of for
fair value,  in the  ordinary  course of business,  or have been  disposed of as
obsolete  since the date of such balance  sheets),  subject to no  encumbrances,
liens,  mortgages,  security  interests or pledges,  except (i) those items that

amounts not yet  delinquent  or which are being  contested in good faith,  (iii)
liens for current  taxes not yet due and  payable,  (iv) such  imperfections  of
title,  easements  and  encumbrances,  if any, as are not material in character,
amount  or  extent,   and  (v)   dispositions   and  encumbrances  for  adequate
consideration in the ordinary course of business. NPB has the right under leases
of material  properties used by NPB in the conduct of its business to occupy and
use all such properties in all material respects as presently  occupied and used
by it.

         (b) With respect to all agreements  pursuant to which NPB has purchased
securities subject to an agreement to resell, if any, NPB has a valid, perfected
first lien or security  interest in the securities or other collateral  securing
the repurchase agreement, and the value of such collateral equals or exceeds the
amount of the debt  secured  thereby,  except to the extent  that any failure to
obtain such a lien or maintain such collateral would not, individually or in the
aggregate, have a Material Adverse Effect.

         (c) NPB currently  maintains  insurance in amounts considered by NPB to
be reasonable  for its  operations,  and such  insurance is similar in scope and
coverage  in all  material  respects  to that  maintained  by  other  businesses
similarly situated.  NPB has not received notice from any insurance carrier that
(i) such insurance will be cancelled or that coverage thereunder will be reduced
or  eliminated,  or (ii) premium  costs with respect to such  insurance  will be
substantially  increased  except to the  extent  such  cancellation,  reduction,
elimination or increase would not have a Material Adverse Effect.

administrative,  arbitration or other  proceedings,  claims,  actions,  customer
complaints,  or  governmental  investigations  or  inquiries  of any  nature (i)
against  NPB or any NPB  Subsidiary,  (ii) to which the assets of NPB or any NPB
Subsidiary are subject,  (iii)  challenging  the validity or propriety of any of

adversely  affect the  ability of NPB or Bank to perform its  obligations  under
this Agreement, except for any proceedings, claims, actions, investigations,  or
inquiries  referred  to in clauses  (i) or (ii)  which,  individually  or in the

authorizations  necessary for the lawful conduct of their respective  businesses
under,  and have  complied  in all  material  respects  with,  applicable  laws,
statutes,  orders,  rules or regulations of any Regulatory Authority relating to
them, other than where such failure to hold or such  noncompliance  will neither
result  in a  limitation  in any  material  respect  on  the  conduct  of  their
respective businesses nor otherwise have a Material Adverse Effect.

         (b) NPB and its Subsidiaries have filed all reports,  registrations and
statements,  together  with any  amendments  required  to be made  with  respect
thereto, that they were required to file with any Regulatory Authority, and have

without  limitation any report or statement required to be filed pursuant to the
laws,  rules or regulations  of the United  States,  any state or any Regulatory
Authority,  and have paid all fees and assessments due and payable in connection
therewith,  except  where the  failure  to file  such  report,  registration  or
statement or to pay such fees and  assessments,  either  individually  or in the
aggregate, will not have a Material Adverse Effect.

         (c) No Regulatory  Authority has  initiated any  proceeding  or, to the
knowledge of NPB,  investigation into the businesses or operations of NPB or any
of its Subsidiaries,  except where any such proceedings or  investigations  will

proceedings or investigations have been terminated or otherwise resolved.

         (d) Neither NPB nor any NPB Subsidiary has received any notification or
communication  from any  Regulatory  Authority (i) asserting that NPB or any NPB
Subsidiary has not complied with any of the statutes,  regulations or ordinances

withdrawn  or  otherwise  resolved;  (ii)  threatening  to revoke  any  license,
franchise,  permit or governmental authorization which is material to NPB or any

enter into a cease and desist order, agreement or memorandum of understanding or
any other agreement restricting or limiting, or purporting to restrict or limit,
in any manner the operations of NPB or any NPB  Subsidiary;  or (iv)  directing,
restricting  or limiting,  or  purporting to direct,  restrict or limit,  in any
manner  the  operations  of  NPB  or  any  NPB  Subsidiary   (any  such  notice,
communication,  memorandum, agreement or order described in this sentence herein
referred to as a "Regulatory Agreement") in each case except as would not have a
Material  Adverse  Effect.  Neither  NPB nor any NPB  Subsidiary  has  received,
consented  to, or  entered  into any  Regulatory  Agreement  which  would  have,
individually or in the aggregate, a Material Adverse Effect.

         (e)  To  the  knowledge  of  NPB,  there  is no  unresolved  violation,
criticism,  or  exception  by  any  Regulatory  Authority  with  respect  to any
Regulatory  Agreement  which if resolved in a manner adverse to NPB would have a
Material Adverse Effect.

         (f) There is no injunction,  order, judgment or decree imposed upon NPB
or any NPB Subsidiary or the assets of NPB or any NPB Subsidiary  which has had,
or, to the knowledge of NPB, will have, a Material Adverse Effect.

insurance plans, and all other employee welfare benefit plans within the meaning
of  ERISA  Section  3(1)  (including   vacation  pay,  sick  leave,   short-term

employee benefit plans, policies, agreements and arrangements,  all of which are
set forth in NPB Disclosure Schedule 3.11,  currently  maintained or contributed
to for the  benefit of the  employees  or former  employees  (including  retired

the Internal  Revenue  Service with respect to any pension plan qualified  under
IRC  Section  401(a),   except  liabilities  to  the  Pension  Benefit  Guaranty
Corporation  pursuant to ERISA Section 4007,  all of which have been fully paid,
nor has any reportable  event under ERISA Section 4043(b) (with respect to which
the 30 day notice  requirement has not been waived) occurred with respect to any
such pension plan.  NPB has not incurred any liability  under ERISA Section 4201
for a complete  or  partial  withdrawal  from a  multi-employer  plan.  Each NPB
Benefit Plan has been maintained, operated and administered in compliance in all
respects with its terms and related  documents or agreements  and the applicable
provisions  of all  laws,  including  ERISA and the IRC,  except  where any such
non-compliance  would not have a Material Adverse Effect. As of the date hereof,
NPB is not aware of any existing or contemplated  audit of its employee  benefit
plans by the Internal Revenue Service or the U.S. Department of Labor.

         (b) With respect to any services  which NPB or any NPB  Subsidiary  may
provide as a sponsor, fiduciary,  trustee or otherwise for any plan, program, or
assignment  subject to ERISA (other than any NPB Benefit Plan), NPB and each NPB
Subsidiary  (i) has  correctly  computed  all  contributions,  payments or other
amounts  for which it is  responsible,  (ii) has not  engaged in any  prohibited
transactions  (as defined in ERISA  Section 406 for which an exemption  does not

of any  ERISA  plan as a result  of any  negligence  in the  performance  of its
duties,  except  where any such  action or  inaction  would not have a  Material
Adverse Effect.

         3.12  Brokers  and  Finders.  Neither  NPB  nor  any of  its  officers,
directors,  employees,  independent  contractors  or agents,  has  employed  any
broker,  finder,  investment  banker  or  financial  advisor,  or  incurred  any
liability for any fees or commissions to any such person, in connection with the

knowledge of NPB,  neither NPB, any NPB  Subsidiary,  nor any property  owned or
operated by NPB or any NPB  Subsidiary  has been or is in violation of or liable
under any  Environmental  Law, except for such  violations or liabilities  that,
individually  or in the  aggregate,  would not have a Material  Adverse  Effect.
Except as disclosed in NPB Disclosure Schedule 3.13, there are no actions, suits
or proceedings,  or demands,  claims or notices,  including  without  limitation
notices,  demand  letters  or  requests  for  information  from  any  Regulatory

investigation  pending,  relating to the liability of NPB or any NPB  Subsidiary
with  respect to any  property  owned or operated  by NPB or any NPB  Subsidiary
under any  Environmental  Law,  except as to any such  actions or other  matters
which will not result in a Material Adverse Effect.

         (b) Except as set forth on NPB  Disclosure  Schedule 3.13, no property,
now or formerly  owned or operated by NPB or any NPB  Subsidiary or on which NPB
or any NPB Subsidiary holds or held a mortgage or other security interest or has
foreclosed  or taken a deed in lieu,  has been listed or proposed for listing on
the  National  Priority  List  under the  Comprehensive  Environmental  Response
Compensation  and  Liability  Act of  1980,  as  amended,  on the

<PAGE>

Comprehensive  Environmental  Response Compensation and Liabilities  Information
System, or any similar state list, or which is the subject of federal,  state or

investigation,  damage to natural  resources or for personal  injury or property
damage claim,  including,  but not limited to, claims under CERCLA,  which would
have a Material Adverse Effect.

         3.14 Business of NPB. Since June 30, 1998, NPB has not, in any material
respect,  (i)  increased  the wages,  salaries,  compensation,  pension or other

eliminated  employee  benefits,  (iii)  deferred  routine  maintenance  of  real
property or leased  premises,  (iv)  eliminated  a reserve  where the  liability
related to such reserve has remained, (v) failed to depreciate capital assets in
accordance with past practice or to eliminate capital assets which are no longer
used in the businesses of NPB, or (vi) had  extraordinary  reduction or deferral
of ordinary or necessary expenses.

provisions  of the CRA,  and,  as of the date  hereof,  Bank has  received a CRA
rating of  "satisfactory"  or better from the OCC.  Neither NPB nor Bank know of
any fact or circumstance or set of facts or circumstances which would cause Bank
to fail to comply with such  provisions  in a manner which would have a Material
Adverse Effect.

         3.16  Allowance  for Loan Losses.  The allowance for loan losses shown,
and to be shown,  on the balance  sheets  contained in the NPB  Financials  have
been, and will be, established in accordance with generally accepted  accounting
principles and all applicable regulatory criteria.

         3.17  Information to be Supplied.  The information  supplied by NPB for
inclusion  in  the  Registration   Statement   (including  the  Prospectus/Proxy
Statement)  will  not,  at the  time  the  Registration  Statement  is  declared
effective   pursuant   to  the   Securities   Act,   and  as  of  the  date  the
Prospectus/Proxy  Statement is mailed to  shareholders  of ENB and NPB and up to
and including the dates of the meetings of  shareholders of ENB and NPB to which
such  Prospectus/Proxy  Statement  relates,  contain any untrue  statement  of a
material fact or omit to state any material fact  necessary in order to make the
statements made therein,  in the light of the  circumstances  in which they were
made,  not  misleading.  The  information  supplied by NPB for  inclusion in the
Applications  will,  at the time such  documents  are filed with any  Regulatory
Authority and up to and including the dates of any required regulatory approvals
or  consents,  as it may be amended by  subsequent  filings,  be accurate in all
material respects.

         3.18 Related Party Transactions.  Except as disclosed in NPB Disclosure
Schedule 3.18 or in the footnotes to the NPB Financials,  as of the date hereof,
NPB is not a party  to any  transaction  (including  any  loan or  other  credit
accommodation  but excluding  deposits in the ordinary  course of business) with
any Affiliate of NPB; and all such  transactions  (i) were made on substantially
the same terms, including interest rates and collateral,  as those prevailing at
the time for comparable  transactions  with other persons (as defined in Section
13(d) of the Exchange  Act, and the rules and  regulations  thereunder),  except
with respect to  variations in such terms as would not,  individually  or in the
aggregate, have a Material Adverse Effect. Except as set forth in NPB Disclosure
Schedule  3.18, as of the date hereof,  no loan or credit  accommodation  to any
Affiliate of NPB is presently in default or, during the three-year  period prior
to the  date  of this  Agreement,  has  been in  material  default  or has  been
restructured,  modified or  extended  in any manner  which would have a Material
Adverse  Effect.  To NPB's  knowledge,  as of the  date  hereof,  principal  and
interest  with  respect to any such loan or other credit  accommodation  will be
paid when due and the loan  grade  classification  accorded  such loan or credit
accommodation is appropriate.

         3.19 Loans.  Each loan  reflected as an asset in the NPB Financials (a)
is evidenced by notes,  agreements or other evidences of indebtedness  which are
true,  genuine and correct and (b) to the extent  secured,  has been  secured by
valid liens and security interests which have been perfected, in each case other
than loans as to which the failure to satisfy the foregoing  standards would not
have a Material Adverse Effect on NPB.

         3.20 Accounting for the Merger; Reorganization.  As of the date hereof,
NPB does not have any reason to believe that the Merger will fail to qualify (i)
for  "pooling  of  interests"  accounting  treatment  under  generally  accepted
accounting  principles,  or (ii) as a reorganization under Section 368(a) of the
IRC.  NPB shall  not take any  action  which  would  preclude  the  Merger  from
qualifying  for "pooling of  interests"  accounting  treatment  under  generally
accepted  accounting  principles  or as a  reorganization  within the meaning of
Section 368 of the IRC.

Letters 97-10  (December  17, 1997) and 98-1  (January 20, 1998),  except to the
extent that the failure so to comply would not have a Material Adverse Effect.

         3.23 NPB Common Stock.  The shares of NPB Common Stock to be issued and
delivered to ENB shareholders in accordance with this Agreement,  when so issued
and  delivered,  will be  validly  authorized  and  issued  and  fully  paid and

proxy  materials will comply,  with the rules and  regulations of the SEC to the
extent applicable thereto, and all such SEC reports, filings and proxy materials
did not and will not, at the time of such filing,  contain any untrue  statement
of a  material  fact or omit to state a  material  fact  required  to be  stated
therein  or  necessary  to make  the  statements  therein,  in the  light of the
circumstances in which they were made, not misleading.

a  streamlined  merger  application  (the  "Merger  Application")  and obtain an

account, other than in the ordinary course of business,  involving an unbudgeted
expenditure by ENB of more than $250,000, or extending beyond twelve (12) months
from the date hereof;

         (q) take any action that would preclude the Merger from  qualifying (A)

accounting  principles or (B) as a reorganization  within the meaning of Section
368 of the IRC; or

         (r) agree to do any of the foregoing.

         4.02  Access; Confidentiality.

         (a) Through the Closing  Date,  each party  hereto  shall afford to the
other, including its authorized agents and representatives, reasonable access to
its properties, assets, books and records and personnel, at reasonable hours and
after reasonable  notice; and the officers of each party shall furnish the other
party  making  such   investigation,   including  its   authorized   agents  and
representatives,  with such financial and operating  data and other  information
with  respect to the  businesses,  properties,  assets,  books and  records  and
personnel as the party making such  investigation,  or its authorized agents and
representatives, shall from time to time reasonably request.

         (b) Each party  hereto  agrees that it, and its  authorized  agents and
representatives,  will conduct such investigation and discussions hereunder in a
confidential   manner  and  otherwise  in  a  manner  so  as  not  to  interfere
unreasonably  with the other party's normal operations and customer and employee
relationships.  Neither ENB nor NPB, nor any of their  respective  Subsidiaries,
shall be required to provide access to or disclose information where such access
or disclosure  would  violate or prejudice  the rights of customers,  jeopardize
attorney-client  privilege or similar privilege with respect to such information
or contravene  any law,  rule,  regulation,  decree,  order,  fiduciary  duty or
agreement entered into prior to the date hereof.

         (c) All information  furnished to NPB or ENB by the other in connection
with the transactions contemplated by this Agreement,  whether prior to the date
of this  Agreement or  subsequent  hereto,  shall be held in  confidence  to the
extent required by, and in accordance with, the two  confidentiality  agreements
dated June 15, 1998  between  NPB and ENB  (collectively,  the  "Confidentiality
Agreements").

         4.03  Regulatory Matters.  Through the Closing Date:

         (a) NPB and ENB shall  cooperate with one another in the preparation of
the Registration  Statement (including the  Prospectus/Proxy  Statement) and all
Applications  and the making of all filings for, and shall use their  reasonable
best  efforts to obtain,  as promptly as  practicable,  all  necessary  permits,
consents,  approvals,  waivers and authorizations of all Regulatory  Authorities
necessary or advisable  to  consummate  the  transactions  contemplated  by this
Agreement,  and in particular,  NPB shall use its reasonable efforts to file the
Merger  Application  within  one month of the date  hereof.  Each of NPB and ENB
shall give the other reasonable time to review any Application to be filed by it
prior to the filing of such Application with the relevant Regulatory  Authority,
and each shall  consult one another with respect to the  substance and status of
such filings.  It is the intent of the parties hereto to cause the  Registration
Statement (including the Prospectus/Proxy Statement) to be declared effective by
the SEC with financial information included therein as of June 30, 1998, subject
to the terms of this Agreement (including the right of ENB to designate the date
of the ENB  Shareholders  Meeting  pursuant to Section  4.07(a)(i)) and provided
further NPB acknowledges that ENB is not a registrant under the Exchange Act and
accordingly preparation of additional information may be required.

         (b) ENB and NPB shall each  promptly  furnish  the other with copies of
written communications to, or received by them from, any Regulatory Authority in
respect of the transactions contemplated hereby.

         (c) ENB and NPB  shall  cooperate  with  each  other  in the  foregoing
matters and shall furnish the other with all  information  concerning  itself as
may be  necessary or advisable in  connection  with any  Application  or filing,
including the Registration  Statement and any report filed with the SEC, made by
or on behalf of such party to or with any  Regulatory  Authority  in  connection
with the  transactions  contemplated by this  Agreement,  and in each such case,
such  information  shall be accurate and complete in all material  respects.  In
connection therewith, ENB

                                     II-23
<PAGE>

and NPB shall use their  reasonable  good faith  efforts  to provide  each other
certificates,  "comfort" letters and other documents reasonably requested by the
other.

         4.04 Taking of Necessary Actions. Through the Closing Date, in addition
to the  specific  agreements  contained  herein,  each  party  hereto  shall use
reasonable best efforts to take, or in the case of NPB cause to be taken by each
of its Subsidiaries,  all actions,  and to do, or in the case of NPB cause to be
done by each of its  Subsidiaries,  all things  necessary,  proper or  advisable
under  applicable  laws and  regulations  to consummate  and make  effective the
transactions  contemplated by this Agreement including, if necessary,  appealing
any adverse ruling in respect of any Application.

         4.05 No  Solicitation.  ENB shall not, nor shall it authorize or permit
any of its officers,  directors or employees or any investment banker, financial
advisor,  attorney,  accountant  or  other  representative  retained  by it  to,
initiate,  solicit,  encourage (including by way of furnishing information),  or
take any other action to facilitate, any inquiries or the making of any proposal
which constitutes any Acquisition  Proposal (as defined below), or enter into or
maintain or continue  discussions or negotiate with any person in furtherance of
an Acquisition Proposal,  or agree to or endorse any Acquisition  Proposal,  and
ENB shall (unless it believes such  notification  could violate the ENB Board of
Directors'  fiduciary  duties)  notify  NPB  as  promptly  as  practicable,   in
reasonable  detail,  as to any inquiries  and  proposals  which it or any of its
representatives or agents may receive; provided,  however, that, notwithstanding
anything to the  contrary  contained in this  Agreement,  (i) ENB may furnish or
cause to be furnished confidential and non-public information concerning ENB and
its  businesses,  properties or assets to a third party,  (ii) ENB may engage in
discussions or negotiations  with a third party,  (iii) following  receipt of an
Acquisition  Proposal,  ENB may take and disclose to its shareholders a position
with respect to such Acquisition  Proposal,  and/or (iv) following receipt of an
Acquisition  Proposal,  the ENB Board of  Directors  may  withdraw or modify its
recommendation of the Merger or terminate this Agreement,  but in respect of the
foregoing  clause (iv) only to the extent that the ENB Board of Directors  shall
conclude in good faith after  consultation with its legal and financial advisors
that such  Acquisition  Proposal,  if consummated  pursuant to its terms,  would
result in an alternative  transaction that is more favorable to ENB shareholders
than the Merger. As used herein, the term "Acquisition  Proposal" means: (x) any
acquisition  or  purchase of a  significant  amount of the assets of ENB, or any
equity interest in ENB or any take-over bid or tender offer (including an issuer
bid or self tender offer) or exchange offer, consolidation, plan or arrangement,
reorganization,  consolidation,  business combination, sale of substantially all
of the assets, sale of securities, recapitalization, liquidation, dissolution or
similar transaction  involving ENB (other than the transactions  contemplated by
this  Agreement)  or  (y)  any  proposal,  plan  or  intention  to do any of the
foregoing  either publicly  announced or communicated to ENB or any agreement to
engage in any of the foregoing.

         4.06 Update of  Disclosure  Schedules.  Through the Closing  Date,  ENB
shall  update  the  ENB  Disclosure  Schedule,  and  NPB  shall  update  the NPB
Disclosure  Schedule,  as promptly as  practicable  after the  occurrence of any
event  which,  if such event had occurred  prior to the date hereof,  would have
been disclosed on such schedule.

         4.07  Other Undertakings by NPB and ENB.

         (a)  Undertakings of ENB.

                  (i) Shareholder  Approval.  ENB shall submit this Agreement to
its  shareholders  for  approval at a meeting (the "ENB  Shareholders  Meeting")
which  may,  in  ENB's  sole  discretion,  be held  after  all  consents  of any
Regulatory  Authorities  have been obtained.  In the event that any such consent
has not been  obtained  prior to the date  established  in the  Prospectus/Proxy
Statement  for such  meeting,  such meeting may be postponed or adjourned at the
sole  discretion  of ENB. The ENB  Shareholders  Meeting shall be held not later
than 45 days after all consents of Regulatory Authorities have been received and
all other  conditions have been satisfied or waived (other than those conditions
which are to be fulfilled at the Closing).

                  (ii) Phase I Environmental Audit. ENB shall permit NPB, if NPB
elects to do so, at its own cost and expense,  to cause a "phase I environmental
audit" to be performed at any physical  location owned or occupied by ENB or any
ENB Subsidiary.

                  (iii) Delivery of Financial  Statements.  ENB shall deliver to
NPB,  as soon as  practicable  after the end of each  month and after the end of
each calendar  quarter prior to the Effective  Date,  commencing  with the


                                     II-24
<PAGE>

month ended July 31, 1998,  an unaudited  consolidated  balance sheet as of such
date and related unaudited consolidated  statements of income and cash flows for
the periods then ended, which financial  statements shall fairly present, in all
material respects, ENB's consolidated financial condition, results of operations
and cash flows for the periods then ended in accordance with generally  accepted
accounting  principles,  except as noted  therein and subject to year-end  audit
adjustments and footnotes.

                  (iv)  Reserves  and  Merger-Related  Costs.  On or before  the
Effective  Date,  establish  such  additional  accruals  and  reserves as may be
necessary to conform ENB's accounting  reserve practices and methods  (including
credit loss  practices  and  methods) to those of NPB and  otherwise  to reflect
Merger-related  expenses and costs incurred by ENB (including  professional fees
and expenses),  in each case on a mutually  satisfactory basis and in accordance
with generally  accepted  accounting  principles  and any applicable  regulatory
requirements,  provided,  however,  that ENB shall not be  required to take such
actions until such time as NPB shall  acknowledge in writing that all conditions
to NPB's and ENB's  respective  obligations  to consummate the Merger (and NPB's
and ENB's  respective  rights to terminate  this  Agreement for any reason) have
been  waived or  satisfied,  and that in all  circumstances  ENB shall take such
actions at such time as shall be mutually agreed to by NPB and ENB but not later
than immediately prior to the time the Merger becomes effective. No action taken
by ENB in accordance with this Section 4.07(a)(iv) shall constitute or be deemed
to be a breach or violation of any representation, warranty, covenant, condition
or  other  provision  of this  Agreement,  and NPB  agrees  to  indemnify  ENB's
officers, directors and agents with respect to such adjustments.

                  (v) Dividend Reinvestment Plan. Within ten days after the date
of this  Agreement,  suspend  through  the  earlier of the  termination  of this
Agreement or the Closing Date the operation of the ENB Dividend Reinvestment and
Stock Purchase Plan.

         (b) Understandings of NPB and ENB.

                  (i) Filings and  Approvals.  NPB and ENB shall  cooperate with
each other in the  preparation and filing,  as soon as  practicable,  of (A) the
Applications,  (B) the Registration  Statement  (including the  Prospectus/Proxy
Statement) and related filings,  if any, under state securities laws relating to
the Merger, (C) all other documents  necessary to obtain any other approvals and
consents  required to effect  consummation of the  transactions  contemplated by
this Agreement.

                  (ii)  Public  Announcements.  NPB and ENB shall agree upon the
form and  substance  of any press  release  related  to this  Agreement  and the
transactions  contemplated  hereby,  but nothing contained herein shall prohibit
either  party,  following  notification  to the other  party,  from  making  any
disclosure which its counsel deems necessary under applicable law.

                  (iii)  Maintenance  of Insurance.  NPB and ENB shall  maintain
insurance in such amounts as NPB or ENB, as the insured, believes are reasonable
to cover such risks as are  customary in relation to the  character and location
of their respective properties and the nature of their respective businesses.

                  (iv)  Maintenance  of Books  and  Records.  NPB and ENB  shall
maintain books of account and records on a basis consistent with past practice.

                  (v) Taxes. NPB and ENB shall each file all federal, state, and
local tax returns  required to be filed by it on or before the date such returns
are due,  including  any  extensions,  and pay all taxes shown to be due on such
returns  on or before  the dates  such  payments  are due,  except  those  being
contested in good faith.

                  (vi)  Integration  Team. NPB and ENB shall cooperate with each
other in the  selection of an  integration  team,  made up of an equal number of
persons from NPB's senior  staff and from ENB's senior  staff,  which team shall
plan and implement an orderly,  cost-effective consolidation of ENB's operations
into Bank's operations in Boyertown, Pennsylvania.

                  (vii)  Outside  Service  Bureau  Contracts.  NPB and ENB shall
cooperate with each other, and if mutually agreed in the interest of an orderly,
cost-effective   consolidation   of   operations,   terminate  any  contract  or
arrangement  ENB may have with an  outside  service  bureau  or other  vendor of
services and  substitute a contract or  



                                     II-25
<PAGE>

arrangement  between NPB or Bank (as NPB shall elect) and ENB for the  provision
of similar  services to ENB on terms and conditions  mutually  acceptable to ENB
and NPB.

                  (viii)  In-House  Operations.  NPB and ENB  shall,  subject to
applicable legal requirements, cooperate with each other, and if mutually agreed
in the  interest  of an orderly,  cost-effective  consolidation  of  operations,
terminate any in-house  back office,  support,  processing or other  operational
activities of ENB, and substitute a contract or arrangement  between NPB or Bank
(as NPB shall  select) and ENB for the  provision of similar  services to ENB on
terms and conditions mutually acceptable to ENB and NPB.

                  (ix) Dividends.  NPB and ENB shall  coordinate with each other
the payment of  dividends  with respect to NPB Common Stock and ENB Common Stock
and the record dates and payment dates relating thereto,  it being the intention
of the parties  hereto that the holders of NPB Common Stock and ENB Common Stock
shall not receive two dividends, or fail to receive one dividend, for any single
calendar quarter with respect to their shares of NPB Common Stock and ENB Common
Stock or any shares of NPB Common Stock  received in exchange for such shares of
ENB Common Stock in the Merger.

         (c) Undertakings of NPB.

                  (i) Shareholders'  Meeting. NPB shall submit this Agreement to
its shareholders for approval at the NPB Shareholders Meeting to be held as soon
as  practicable,  or, in the  discretion  of NPB,  at any time  prior to the ENB
Shareholders  Meeting, with the recommendation of its Board of Directors to such
shareholders  to approve this Agreement and the issuance of the NPB Common Stock
for purposes of the Nasdaq requirements.

                  (ii)  Delivery  of SEC  Documents.  NPB shall  deliver  to ENB
copies of all reports  filed with the SEC under the Exchange  Act promptly  upon
the filing thereof.

                  (iii) Delivery of Financial  Statements.  NPB shall deliver to
ENB,  as soon as  practicable  after the end of each  month and after the end of
each calendar  quarter prior to the Effective  Date,  commencing  with the month
ended July 31, 1998, an unaudited consolidated balance sheet as of such date and
related  unaudited  consolidated  statements  of income  and cash  flows for the
periods then ended,  which financial  statements  shall fairly  present,  in all
material respects, NPB's consolidated financial condition, results of operations
and cash flows for the periods then ended in accordance with generally  accepted
accounting  principles,  except as noted  therein and subject to year-end  audit
adjustments and footnotes.

                  (iv) Employees,  Severance  Policy.  Upon  consummation of the
Merger,  NPB shall  offer,  or cause Bank or another  NPB  Subsidiary  to offer,
employment  to each person who is then an ENB employee,  in accordance  with the
employment  and  severance  policies  set  forth  herein  and on NPB  Disclosure
Schedule 4.07(c)(iv) (the "Merger Employment  Policies").  The provisions herein
shall  control any  inconsistent  provision of the Merger  Employment  Policies.
Notwithstanding  any  provision  of  this  Agreement  to  the  contrary,  unless
involuntarily  terminated  without  "cause"  prior to such time, no ENB employee
shall be entitled  to  severance  benefits  unless such  employee  continues  in
employment for 30 days following the actual  consolidation and conversion of the
ENB operating  system with and into the Bank's operating system (the "Conversion
Date").  As  provided  in the  Merger  Employment  Policies,  NPB shall  provide
severance  benefits to each ENB employee who is not offered employment with NPB,
who does not accept employment with NPB (except as provided in clause (A) (B) or
(C) below),  or whose  employment  with NPB is terminated by NPB without "cause"
within one year after the Effective Date,  excluding,  however, any ENB employee
who is a party to an  employment,  "change-in-control",  or  similar  agreement.
Severance  benefits shall consist of one week's pay (at current levels) for each
year of service (to be paid as salary  continuation),  a lump sum payment of all
unused vacation time (to be paid as soon as practicable  following  termination)
and the continuation of all applicable  welfare plan benefits until the last day
of the month  during  which the last week of  severance  is paid.  All  eligible
employees  shall be entitled to a minimum of eight weeks of  severance  benefits
and shall be given full  credit for each year of service  with ENB.  Any partial
year of  service  shall be  treated  as a full year for  purposes  of  severance
benefit calculations.  Except as provided below, severance benefits shall not be
payable to: (A) any ENB employee whose current employment position is maintained
as it was  immediately  prior to the  Effective  Date;  (B) any  non-exempt  ENB
employee who  receives  and turns down two job offers of equal or higher  salary
grade at a location within a 15 mile radius of the employee's  home; and (C) any
exempt ENB  employee  who receives and turns down a job offer of equal or higher
salary grade at a location  within 



                                     II-26
<PAGE>

a 25 mile radius of the employee's home. NPB shall also make severance  benefits
available  to ENB  personnel  whose  employment  with NPB is  terminated  by NPB
without "cause" within one year after the Effective Date, in accordance with the
Merger Employment  Policies.  Notwithstanding the foregoing,  each full-time ENB
non-community  office and non-lending  staff employee (i.e., all employees other
than community office staff, lending staff and lending office support personnel)
whose employment position has not been maintained as it was immediately prior to
the Effective Date and who has received the offer(s) of employment  specified in
clause (B) or (C) above and who elects not to accept an offer of employment with
NPB (or who  elects to  terminate  employment  with NPB  within  365 days of the
Effective  Date)  shall be  entitled to four weeks of  severance  benefits.  Any
person whose  employment with NPB is terminated by NPB without "cause" after one
year from the Effective Date shall receive such severance benefit from NPB as is
provided for in NPB's general severance policy for such terminations  (with full
credit  being  given for each year of service  with ENB).  For  purposes of this
Section  4.07(c)(iv),  "cause" shall mean the employer's  good faith  reasonable
belief  that  the  employee  committed  fraud,  theft,  embezzlement,  falsified
corporate records,  disseminated  confidential information concerning customers,
NPB, Bank or its employees, had documented  unsatisfactory job performance under
Bank's  dismissal  policy,  or violated  Bank's Code of Conduct.  The  foregoing
definition of "cause" is the  definition of "cause" used by Bank in the ordinary
course of its business.

                  (v) Employee Benefits. As of the Effective Date, ENB employees
who become  employees of NPB or of any NPB Subsidiary  shall be entitled to full
credit for each year of service with ENB for purposes of determining eligibility
for  participation  and  vesting,  but not benefit  accrual,  in NPB's  employee
benefit plans,  programs and policies.  The employee benefits provided to former
employees of ENB after the Effective Date shall be substantially  similar to the
employee  benefits,  in the aggregate,  provided by NPB or its  Subsidiaries  to
their similarly situated employees.  The NPB medical,  dental and life insurance
plans,  programs  or  policies,  if any,  that become  applicable  to former ENB
employees  shall not contain any  exclusion  or  limitation  with respect to any
pre-existing condition of any such employees or their dependents. Subject to the
foregoing, after the Effective Date, NPB may discontinue, amend or convert to an
NPB plan any particular  benefit or welfare plan of ENB,  subject to such plan's
provisions and applicable law.

                  (vi) Qualified  Plans.  As of the Effective  Date, the account
balances of ENB employees under the ENB 401(k) Profit Sharing Plan and under the
ENB Employee  Stock  Ownership Plan shall become 100 percent  vested,  provided,
however,  such  vesting  shall not take place if such  vesting  would  cause the
Merger to fail to qualify for "pooling of interests" accounting treatment.

                  (vii) Management Incentive Plan. If the Merger occurs prior to
December 31, 1998, the annual portion of the ENB Management  Incentive Plan (the
"MIP") shall be continued  through December 31, 1998. If the Merger occurs after
December 31, 1998, the MIP may be continued or discontinued as determined by the
NPB Board of Directors. In any event, the ENB Board of Directors shall determine
in good faith,  with the consent of NPB (which consent shall not be unreasonably
withheld),  the appropriate  level of payouts to be made under the MIP for 1998.
In making its  determination,  the ENB Board of Directors  shall  disregard  any
extraordinary  expenses or charges  related to the Merger  that would  otherwise
cause a reduction in payouts under the MIP.

                  (viii)  Calculations  of ESOP,  MIP and  Profit  Sharing.  The
calculations  determining the amounts to be included in the ESOP, MIP and profit
sharing plans for 1998 shall be done prior to making any deductions for reserves
to be created or expenses incurred in connection with the Merger.

                  (ix) Deferred Compensation Arrangement.  On the Effective Date
or on January 1, 1999 if the Effective  Date shall precede  January 1, 1999, the
ENB Deferred  Compensation  Arrangement shall be terminated,  and subject to any
applicable  income  tax  withholding  requirements,  all  deferred  compensation
account balances shall be paid out in cash to plan participants.

                  (x) Election of NPB Directors. Upon consummation of the Merger
and subject to compliance  with all  applicable  legal  requirements,  NPB shall
elect two  persons  selected  by ENB's Board of  Directors  and  approved by NPB
(which  approval  will  not be  unreasonably  withheld)  as  directors  of  NPB,
effective  the  Effective  Date,  one to serve as a Class I director with a term
through  April  2000 and the other to serve as a Class II  director  with a term
through April 2001, and each to be re-nominated for at least one full three-year
term  thereafter  (each,  an "ENB NPB  Nominee").  In the event that any ENB NPB
Nominee,  or any  successor,  resigns,  dies or is otherwise



                                     II-27
<PAGE>

removed from NPB's Board of  Directors  prior to the end of such  person's  full
three-year term, the Elverson Continuing  Directors,  by a plurality vote, shall
have the right to select  such  person's  successor,  subject to NPB's  approval
(which  approval  will not be  unreasonably  withheld),  and NPB shall  take all
reasonable  steps  necessary  to  elect  such  successor  to the  NPB  Board  of
Directors.

                  (xi)  Elverson Division, Elverson Board.

                           (A) Upon  consummation  of the Merger and  subject to
compliance  with all  applicable  legal  requirements,  NPB shall  cause Bank to
establish and operate a separate  banking  division  called  "Elverson  National
Bank, a Division of National Penn Bank" (the "Elverson Division").  The Elverson
Division  will consist of all ENB's  present  branch  offices with the following
additions and  deletion:  (1) Bank's  Lionville  office would become an Elverson
Division  office;  (2) Bank's Gay Street,  West Chester office would be combined
into ENB's office at High Street,  West Chester;  and (3) ENB's  Sinking  Spring
office would  become a Bank  office.  It is NPB's intent to utilize the Elverson
Division in the  expansion of NPB's  branch  banking  system in Chester  County,
Pennsylvania, either by the opening of de novo branches or by the acquisition of
deposits and assets,  such branches to be operated under the "Elverson Division"
banner.  Subject to NPB's  approval  of the  planned  capital  expenditures  and
operating budget for the proposed  branches,  the Elverson Division may open two
branches in Chester  County in the three years  following  the  Effective  Date;
provided,  however,  that  approval of the second  branch will be subject to the
first branch having achieved $10 million in deposits.  NPB anticipates  that the
Elverson  Division will have the same lending authority limits as ENB has at the
date hereof, in accordance with NPB's credit quality standards.

                           (B) Upon consummation of the Merger,  NPB shall cause
Bank to establish the "Elverson  Division  Board of  Directors"  (the  "Elverson
Board").  The  Elverson  Board  shall  consist of the  members of ENB's Board of
Directors at the Effective Date, an NPB executive  officer  selected by NPB, and
such other  persons as the Elverson  Board shall  select from time to time.  NPB
anticipates  that  the  Elverson  Board  will  emphasize  sales,  marketing  and
expansion.  ENB's  current  non-employee  directors  who  become  members of the
Elverson Board shall receive annual  director  compensation  equal to the annual
director compensation received by them at the date hereof. Other persons who may
be selected for service on the Elverson Board shall be compensated in accordance
with NPB's standard  compensation  arrangements  for  divisional  board members,
which is  partially  fixed and  partially  incentive-based  compensation.  ENB's
current  non-employee  directors who become  members of the Elverson Board shall
have the option of  electing  to receive  such NPB  standard  compensation.  The
Elverson  Board  shall  have  indemnification  and  insurance  coverage  no less
favorable than members of the Board of Directors of Bank.

                           (C) NPB shall  operate  the  Elverson  Division,  and
maintain the Elverson Board at the foregoing compensation level, for a period of
at least five years after the Effective  Date,  except that this covenant  shall
expire if and when NPB shall be acquired or otherwise  sold and  thereafter  the
members  of NPB's  Board of  Directors  do not  constitute  at least  50% of the
members of the surviving corporation's board of directors.

                  (xii)  Indemnification, Insurance.

                           (A) NPB shall  indemnify,  defend,  and hold harmless
the  directors,  officers,  employees and agents of ENB (each,  an  "Indemnified
Party") against all losses,  expenses  (including  reasonable  attorneys' fees),
claims,  damages or  liabilities  and amounts paid in settlement  arising out of
actions or omissions or alleged acts or omissions  (collectively,  "Prior Acts")
occurring  at or  prior  to  the  Effective  Date  (including  the  transactions
contemplated  by this  Agreement)  to the  fullest  extent  permitted  under the
Pennsylvania Business Corporation Law ("PBCL"), including provisions relating to
advances of  expenses  incurred  in the  defense of any  proceeding  to the full
extent  permitted  by the PBCL upon receipt of any  undertaking  required by the
PBCL.  Without  limiting  the  foregoing,   in  a  case  (if  any)  in  which  a
determination  by NPB is required to effectuate any  indemnification,  NPB shall
direct, at the election of the Indemnified  Party, that the determination  shall
be  made  by  independent  counsel  mutually  agreed  upon  between  NPB and the
Indemnified Party.

                           (B) NPB shall cause Bank to keep in effect provisions
in its Articles of Incorporation and Bylaws of Bank providing for exculpation of
director  and  officer  liability  and its  indemnification  of the  Indemnified
Parties to the fullest extent  permitted under the PBCL,  which provisions shall
not be amended  except as required by  applicable  law or except to make changes
permitted  by  law  that  would  enlarge  the  Indemnified   Parties'  right  to
indemnification.

<PAGE>

                           (C) NPB shall use its  reasonable  best  efforts (and
ENB shall cooperate and assist prior to the Effective Date in these efforts), at
no expense to the  beneficiaries,  (i) to maintain (x)  directors' and officers'
liability  insurance ("D&O Insurance") for the Indemnified  Parties with respect
to  matters  occurring  at or prior to the  Effective  Date,  and (y)  fiduciary
liability  insurance   ("Fiduciary   Insurance")  for  the  present  and  former
fiduciaries of ENB's  profit-sharing plan and employee stock ownership plan (the
"Fiduciary  Insurance"),  each  issued  by a  carrier  or  carriers  assigned  a
claims-paying ability rating by A.M. Best & Co. of "A (Excellent)" or higher, or
(ii) to obtain  coverage for Prior Acts for the  Indemnified  Parties  under the
fiduciary and directors' and officers'  liability  insurance  policies currently
maintained  by NPB, in either case,  providing at least the same coverage as the
D&O Insurance and Fiduciary Insurance, respectively, currently maintained by ENB
and  containing  terms  and  conditions  which  are  no  less  favorable  to the
beneficiaries,  for a period of at least six (6) years from the Effective  Date;
provided,  that NPB shall not be  obligated  to make  premium  payments for such
six-year  period in respect of the D&O  Insurance  and the  Fiduciary  Insurance
which exceed,  for the portion  related to ENB's  directors  and  officers,  150
percent of the annual premium payments  ($18,083.00 at the date hereof) of ENB's
current  policy  in  effect  as of the  date of  this  Agreement  (the  "Maximum
Amount").  If the amount of the  premiums  necessary to maintain or procure such
insurance coverage exceeds the Maximum Amount, NPB shall use its reasonable best
efforts to maintain the most  advantageous  policies of directors' and officers'
liability insurance obtainable for a premium equal to the Maximum Amount.

                           (D) In the event any claim is made against present or
former directors,  officers or employees of ENB or any of the Fiduciaries who is
covered or  potentially  covered  by  insurance,  neither  Bank nor NPB shall do
anything  that  would  forfeit,  jeopardize,  restrict  or limit  the  insurance
coverage available for that claim until the final disposition thereof.

                           (E) If NPB or any of its  successors or assigns shall
consolidate  with or merge into any other person and shall not be the continuing
or surviving  person of such  consolidation  or merger or shall  transfer all or
substantially  all of its assets to any  person,  then and in each case,  proper
provision  shall be made so that the  successors and assigns of NPB shall assume
the obligations set forth in this Section 4.07(c)(xi).

                           (F) The  provisions of this Section  4.07(c)(xi)  are
intended to be for the benefit of and shall be enforceable by, each  Indemnified
Party, his or her heirs and representatives.

                           (G) NPB shall pay all expenses,  including reasonable
attorneys' fees, that may be incurred by any Indemnified  Party in enforcing the
indemnity and other obligations provided for in this Section 4.07(c)(xi).

                  (xiii) Publication of Post-Merger  Results of Operations.  NPB
shall use its reasonable best efforts to publish (if necessary,  on Form 8-K) no
more than twenty days after the end of the first month after the Effective  Date
in which  there are at least  thirty  days of  post-Merger  combined  operations
(which month may be the month in which the Effective Date occurs), the financial
information  contemplated  by and in accordance with the terms of SEC Accounting
Series Releases No. 130 and 135 and Section 201.01 of the SEC's  Codification of
Financial Reporting Policies and other applicable accounting rules.

                  (xiv)  Repurchases  of NPB Common  Stock.  Through the Closing
Date,  except as otherwise  consented to in writing by ENB (which  consent shall
not be unreasonably  withheld),  NPB shall not  repurchase,  redeem or otherwise
acquire any shares of NPB Common Stock.

                  (xv) Conduct of NPB's Business.  Through the Closing Date, NPB
shall  use  its   reasonable   good  faith  efforts  to  preserve  its  business
organization  intact,  maintain good relationships with employees,  and preserve
the good will of  customers of NPB and others with whom  business  relationships
exist,  and in all  material  respects  conduct  its  businesses  and  engage in
transactions in the ordinary course without radical change.

                  (xvi) Other Transactions.  Through the Closing Date, except as
otherwise   consented  to  in  writing  by  ENB  (which  consent  shall  not  be
unreasonably  withheld),  NPB shall not enter  into any  agreement  with a third
party  concerning  any  acquisition  of  such  third  party  by,  or  merger  or
consolidation of such third party with, NPB if (A) under applicable regulations,
NPB would be required to present pro forma financial information reflecting that


                                     II-29

transaction  in the  Registration  Statement,  or (B) NPB would propose to issue
shares of NPB Common Stock in such  transaction  in an amount  exceeding  twenty
percent of the outstanding shares of NPB Common Stock on the date hereof.

<PAGE>

                  (i) If there shall have been any breach of any representation,
warranty or obligation of the other party hereto  (subject to the same standards
as set forth in Sections 5.01(b) or 5.02(b), as the case may be) and such breach
can not be, or shall not have been,  remedied  within 30 days  after  receipt by
such party of written notice specifying the nature of such breach and requesting
that it be remedied;

                  (ii) If the  Closing  Date  shall not have  occurred  prior to
February 28, 1999  (except  that if the Closing Date shall not have  occurred by
such  date  because  of a  breach  of this  Agreement  by a party  hereto,  such
breaching  party (or Bank in NPB's case) shall not be entitled to terminate this
Agreement in accordance with this provision);

                  (iii) If any Regulatory Authority whose approval or consent is
required for consummation of the Merger shall issue a definitive  written denial
of such  approval or consent and the time  period for appeals and  requests  for
reconsideration has run; or

                  (iv) If any shareholder vote contemplated by this Agreement is
not obtained at the ENB Shareholders Meeting or the NPB Shareholders Meeting.

         (c) By ENB,  at any  time  during  the  ten-day  period  following  the
Determination   Date,  if  both  of  the  following   conditions  occur  on  the
Determination Date:

                  (1) the NPB Market  Value  shall be less than $27.00 per share
         [the dollar amount  $27.00 shall be adjusted to $21.60 upon  completion
         of the NPB Stock Split]; and

                  (2)(i) the quotient  obtained by dividing the NPB Market Value
         by $33.75 per share [the  dollar  amount  $33.75  shall be  adjusted to
         $27.00 upon  completion of the NPB Stock Split] shall be less than (ii)
         the quotient  obtained by dividing the Average Index Price by the Index
         Price on the Starting  Date and  subtracting  0.05 from the quotient in
         this clause (2)(ii);

subject,  however,  to the  following:  If ENB  shall  elect to  terminate  this
Agreement pursuant to this Section 6.01(c), it shall give written notice thereof
to NPB  (provided  that such notice of election to terminate may be withdrawn at
any time within the aforementioned  ten-day period).  During the five-day period
commencing  with its receipt of such notice,  NPB shall have the option to elect
to increase the exchange ratio set forth in Section 1.02(f)(ii)(A),  as adjusted
pursuant  to Section  1.02(f)(ii)(E),  to 1.25  shares of NPB Common  Stock [the
number 1.25 shall be adjusted to 1.5625 upon  completion of the NPB Stock Split]
in exchange  for each share of ENB Common  Stock and the  Closing  Date shall be
postponed by the minimum amount of time necessary,  if any, to accommodate NPB's
election of such option (i.e., up to a five-day period). If NPB so elects within
such  five-day  period,  it shall  give  prompt  written  notice  to ENB of such
election,  whereupon no termination shall have occurred pursuant to this Section
6.01(c) and this Agreement  shall remain in effect in accordance  with its terms
(except as the Exchange Ratio shall have been so modified).

         For  purposes of this Section  6.01(c),  the  following  terms have the
meanings indicated.

         "Index Group" means the bank or thrift holding  companies listed below,
the common stocks of all of which shall be publicly traded and as to which there

         If any company belonging to the Index Group declares or effects a stock

shares, or similar  transaction  between the Starting Date and the Determination
Date,  the prices for the common  stock of such company  shall be  appropriately

                       OPINION OF BERWIND FINANCIAL, L.P.


__________, 1998


Board of Directors
Elverson National Bank
83 West Main Street
Elverson, PA  19520

Members of the Board:

         You have  requested  our opinion as to the  fairness,  from a financial
point of view, to the shareholders of Elverson National Bank ("Elverson") of the
financial terms of the proposed merger by and between Elverson and National Penn
Bancshares,  Inc.  ("NPBC").  The terms of the  proposed  merger (the  "Proposed
Merger") by and between  Elverson  and NPBC are set forth in the  Agreement  and
Plan of Merger  dated July 21, 1998 (the  "Merger  Agreement")  and provide that
each outstanding share of Elverson common stock will be converted into the right
to receive  1.46875 shares of NPBC common stock subject to adjustment as defined
in the Merger Agreement.

         Berwind  Financial,  L.P., as part of its investment  banking business,
regularly is engaged in the  valuation of assets,  securities  and  companies in
connection  with  various  types of asset and security  transactions,  including
mergers,  acquisitions,  private  placements  and  valuations  for various other
purposes,   and  in  the   determination  of  adequate   consideration  in  such
transactions.

         In arriving at our opinion,  we have, among other things:  (i) reviewed
the historical financial  performances,  current financial positions and general
prospects  of Elverson  and NPBC,  (ii)  reviewed  the Merger  Agreement,  (iii)
reviewed the Joint Proxy  Statement/Prospectus,  (iv)  reviewed and analyzed the
stock  market  performance  of Elverson  and NPBC,  (v) studied and analyzed the
consolidated  financial and operating data of Elverson and NPBC, (vi) considered
the terms and  conditions of the Proposed  Merger  between  Elverson and NPBC as
compared  with the terms and  conditions  of  comparable  bank and bank  holding
company mergers and  acquisitions,  (vii) met and/or  communicated  with certain
members of Elverson's and NPBC's senior  management to discuss their  respective
operations,  historical  financial  statements and future prospects,  and (viii)
conducted such other financial analyses, studies and investigations as we deemed
appropriate.

         Our  opinion is given in reliance on  information  and  representations
made or given by Elverson and NPBC, and their  respective  officers,  directors,
auditors,  counsel  and  other  agents,  and  on  filings,  releases  and  other
information  issued  by  Elverson  and  NPBC  including  financial   statements,
financial projections,  and stock price data as well as certain information from
recognized   independent  sources.  We  have  not  independently   verified  the
information concerning Elverson and NPBC nor other data which we have considered
in our review and, for purposes of the opinion set forth below,  we have assumed
and relied upon the accuracy and  completeness of all such information and data.
Additionally,  we assume that the Proposed  Merger is, in all  respects,  lawful
under applicable law.

         With regard to financial and other information  relating to the general
prospects of Elverson, we have assumed that such information has been reasonably
prepared and reflects the best currently available estimates and judgment of the
management  of Elverson as to its most likely future  performance.  For Elverson
and NPBC, we have assumed the allowance for loan losses indicated on the balance
sheets of each  entity is adequate to cover such  losses;  we have not  reviewed
credit files of either Elverson or NPBC. Also, in rendering our opinion, we have
assumed that in the course of obtaining the necessary  regulatory  approvals for
the  Proposed  Merger no  conditions  will be imposed  that will have a material
adverse effect on the contemplated benefits of the Proposed Merger to Elverson.


                                     II-39
<PAGE>



         Our opinion is based upon information provided to us by the managements
of  Elverson  and  NPBC,  as well  as  market,  economic,  financial  and  other
conditions  as they exist and can be  evaluated  only as of the date  hereof and
speaks  to  no  other  period.  Our  opinion  pertains  only  to  the  financial
consideration of the Proposed Merger and does not constitute a recommendation to
the Board of  Elverson  and does not  constitute  a  recommendation  to Elverson
shareholders as to how such shareholders should vote on the Proposed Merger.

         Based on the foregoing,  it is our opinion that, as of the date hereof,
the financial terms of the Proposed Merger by and between  Elverson and NPBC are
fair, from a financial point of view, to the shareholders of Elverson.

                                         Sincerely,




                                         BERWIND FINANCIAL, L.P.

                     OPINION OF LSC FINANCIAL SERVICES, INC.


                                                              __________, 1998

The Board of Directors
National Penn Bancshares, Inc.
Philadelphia & Reading Avenues/Box 547
Boyertown, PA 19512

Members of the Board:

         You have  requested  our opinion as to the  fairness,  from a financial
point of view, to the shareholders of National Penn Bancshares,  Inc. ("NPB") of
the Amended  Agreement and Plan of Merger  ("Agreement")  between NPB,  National
Penn Bank ("Bank") and Elverson National Bank and its subsidiaries ("ENB") dated
as of July 21, 1998.

         Under the terms of the Agreement,  each outstanding share of ENB common
stock will be converted  into the right to receive  1.46875 shares of NPB common
stock,  subject  to  possible  adjustment  as set  forth  in the  Agreement.  In
addition,  each of the outstanding options to purchase one or more shares of ENB
common  stock shall be  converted  into an option to purchase the number of full
shares of NPB common stock which the  optionholder  would have been  entitled to
receive  in the  merger  had such  option  been  exercised  in full prior to the
effective  date of the  merger,  at such  exercise  price as  determined  by the
Agreement.

         For purposes of this  opinion,  we reviewed  and  analyzed  information
pertaining to the financial and operating  condition of NPB and ENB. This review
included,  but was not limited to: (i) the  Agreement  and Plan of Merger;  (ii)
financial  and other  information  which was  otherwise  publicly  available  or
provided to us by NPB and ENB; (iii) certain financial  information  relating to
the banking industry in general; (iv) our evaluation of future prospects for the
merged  institution;  and  (v)  such  other  financial  reviews,  analyses,  and
investigations as we deemed appropriate.

         LSC also  reviewed  with  NPB's  management,  the  results of NPB's due
diligence   examination   of  ENB  ;  the  expected  cost  savings  and  revenue
enhancements  related to the Merger,  and the strategic  benefits expected to be
derived from the Merger.

         We have assumed that the  allowances  for loan losses  indicated on the
balance  sheets of NPB and ENB as of June 30,  1998 are  adequate  to cover such
losses. We have not reviewed the loan files of NPB or ENB.

         We assumed that in the course of  obtaining  the  necessary  regulatory
approvals for the Agreement,  no restrictions  will be imposed on NPB that would
have a material adverse effect on the contemplated  benefits of the Agreement to
NPB.  We  further  assumed  that no  change  would  occur in  applicable  law or
regulation  that  would  cause a material  adverse  change in the  prospects  or
operations of NPB after the merger. LSC also assumed,  with NPB's consent,  that
the Merger  will be  accounted  for as a pooling of  interests  under  generally
accepted accounting principles.

         LSC did not  independently  verify the information  used in arriving at
its opinion,  but assumed the accuracy and completeness of all such information.
In that regard,  LSC assumed with NPB's  consent that the  financial  forecasts,
including,  without  limitation,  projected cost savings,  have been  reasonably
prepared  on a basis  reflecting  the best  currently  available  judgments  and
estimates  of the  managements  of NPB and ENB and that such  forecasts  will be
realized in the amounts and at the times contemplated thereby. Also, LSC did not
make or obtain any independent  appraisal of the assets or liabilities of NPB or
ENB.

         Based upon and  subject to the  foregoing,  it is our opinion as of the
date hereof,  that the exchange is fair,  from a financial point of view, to the
shareholders of National Penn Bancshares.

                                        Sincerely,

                                        /s/ LSC Financial Services, Inc.

                      DISSENTING SHAREHOLDERS' RIGHTS UNDER

                    12 UNITED STATES CODE SECTION 215a(b)-(d)



(B)  DISSENTING SHAREHOLDERS

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

(C)  VALUATION OF SHARES

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

(D)  APPLICATION  TO   SHAREHOLDERS  OF  MERGING   ASSOCIATIONS:   APPRAISAL  BY
     COMPTROLLER;  EXPENSES OF RECEIVING ASSOCIATION; SALE AND RESALE OF SHARES;
     STATE APPRAISAL AND MERGER LAW

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

                OCC BANKING CIRCULAR ON STOCK APPRAISAL (BC-259)


                                  March 5, 1992


                                BANKING ISSUANCE

                           COMPTROLLER OF THE CURRENCY

                         ADMINISTRATOR OF NATIONAL BANKS

Type: Banking Circular
Subject: Stock Appraisals

To: Chief Executive Officers of National Banks, Deputy Comptrollers  (District),
Department and Division Heads, and Examining Personnel

PURPOSE

     This Banking Circular  informs all national banks of the valuation  methods
used by the Office of the  Comptroller  of the  Currency  (OCC) to estimate  the
value of a bank's shares when requested to do so by a shareholder  dissenting to
the conversion,  merger, or consolidation of its bank. The results of appraisals
performed  by the OCC  between  January  1, 1985,  and  September  30,  1991 are
summarized.

     References:  12 U.S.C. 214a, 215 and 215a; 12 CFR 11.590 (Item 2)

BACKGROUND

     Under 12 U.S.C.  Section 214a, a shareholder  dissenting from a conversion,
consolidation,  or merger  involving a national  bank is entitled to receive the
value of his or her shares from the  resulting  bank.  A valuation of the shares
shall  be made by a  committee  of three  appraisers  (a  representative  of the
dissenting  shareholder,  a  representative  of the resulting  bank, and a third
appraiser  selected by the other two). If the committee is formed and renders an
appraisal  that is  acceptable  to the  dissenting  shareholder,  the process is
complete  and the  appraised  value  of the  shares  is  paid to the  dissenting
shareholder  by the  resulting  bank.  If, for any reason,  the committee is not
formed or if it renders an appraisal  that is not  acceptable to the  dissenting
shareholder,  an interested party may request an appraisal by the OCC. 12 U.S.C.
Section 215 provides these appraisal  rights to any shareholder  dissenting to a
consolidation.  Any dissenting  shareholder of a target bank in a merger is also
entitled to these appraisal rights pursuant to 12 U.S.C. Section 215a. The above
provides  only  a  general  overview  of the  appraisal  process.  The  specific
requirements of the process are set forth in the statutes themselves.

METHODS OF VALUATION USED

     Through  its  appraisal  process,  the OCC  attempts  to  arrive  at a fair
estimate of the value of a bank's shares.  After reviewing the particular  facts
in each case and the available  information on a bank's shares,  the OCC selects
an appropriate  valuation  method,  or  combination  of methods,  to determine a
reasonable estimate of the shares' value.

MARKET VALUE

     The OCC uses various  methods to establish the market value of shares being
appraised.  If  sufficient  trading  in the  shares  exists  and the  prices are
available  from direct  quotes from the Wall Street  Journal or a  market-maker,
those quotes are considered in determining  the market value. If no market value
is readily available,  or if the market value available is not well established,
the OCC may use other methods of estimating market value, such as the investment
value and adjusted book value methods.


                                     II-44
<PAGE>

INVESTMENT VALUE

     Investment  value  requires an  assessment  of the value to  investors of a
share in the future earnings of the target bank.  Investment  value is estimated
by  applying  an average  price/earnings  ratio of banks with  similar  earnings
potential to the earnings capacity of the target bank.

     The peer group selection is based on location, size, and earnings patterns.
If the state in which the subject bank is located  provides a sufficient  number
of comparable banks using location,  size and earnings  patterns as the criteria
for selection,  the  price/earnings  ratios assigned to the banks are applied to
the  earnings per share  estimated  for the subject  bank.  In order to select a
reasonable peer group when there are too few comparable  independent  banks in a
location that is comparable to that of the subject bank,  the pool of banks from
which a peer group is  selected  is  broadened  by  including  one-bank  holding
company  banks in a  comparable  location,  and/or  by  selecting  banks in less
comparable  locations,  including  adjacent states,  that have earnings patterns
similar to the subject bank.

ADJUSTED BOOK VALUE

     The OCC also uses an "adjusted  book value"  method for  estimating  value.
Historically,  the OCC has not placed any weight on the bank's  "unadjusted book
value", since that value is based on historical  acquisition costs of the bank's
assets, and does not reflect investors'  perceptions of the value of the bank as
an ongoing  concern.  Adjusted book value is calculated by multiplying  the book
value of the target  bank's  assets per share times the average  market price to
book value ratio of comparable banking  organizations.  The average market price
to book value ratio  measures  the  premium or  discount  to book  value,  which
investors attribute to shares of similarly situated banking organizations.

     Both the investment value method and the adjusted book value method present
appraised  values which are based on the target bank's value as a going concern.
These  techniques  provide  estimates  of the market  value of the shares of the
subject bank.

OVERALL VALUATION

     The OCC may use more than one of the  above-described  methods in  deriving
the value of shares of stock.  If more than one method is used,  varying weights
may be applied in reaching an overall  valuation.  The weight given to the value
by a particular  valuation method is based on how accurately the given method is
believed to represent market value. For example, the OCC may give more weight to
a market value representing infrequent trading by shareholders than to the value
derived from the investment  value method when the subject bank's earnings trend
is so irregular that it is considered to be a poor predictor of future earnings.

PURCHASE PREMIUMS

     For mergers and  consolidations,  the OCC recognizes that purchase premiums
do exist and may, in some instances,  be paid in the purchase of small blocks of
shares.  However,  the  payment of  purchase  premiums  depends  entirely on the
acquisition  or  control  plans of the  purchasers,  and such  payments  are not
regular  or  predictable  elements  of  market  value.  Consequently,  the OCC's
valuation methods do not include  consideration of purchase premiums in arriving
at the value of shares.

STATISTICAL DATA

     The chart below lists the results of appraisals  the OCC performed  between
January 1, 1985 and September  30, 1991.  The OCC provides  statistical  data on
book value and  price/earnings  ratios for  comparative  purposes,  but does not
necessarily  rely on such data in  determining  the value of the banks'  shares.
Dissenting  shareholders  should not view these statistics as determinative  for
future appraisals.

     In connection with  disclosures  given to shareholders  under 12 CFR 11.590
(Item 2),  banks may provide  shareholders  a copy of this  Banking  Circular or
disclose the information in the Banking Circular,  including the past results of
OCC appraisals. If the bank discloses the past results of the OCC appraisals, it
should advise shareholders that: (1) the OCC did not rely on all the information
set forth in the chart in  performing  each  appraisal;  and (2) the OCC's  past
appraisals  are not  necessarily  determinative  of its future  appraisals  of a
particular bank's shares.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.          Indemnification of Directors and Officers.

                  Pennsylvania law provides that a Pennsylvania corporation may
indemnify directors, officers, employees and agents of the corporation against
liabilities they may incur in such capacities for any action taken or any
failure to act, whether or not the corporation would have the power to indemnify
the person under any provision of law, unless such action or failure to act is
determined by a court to have constituted recklessness or willful misconduct.
Pennsylvania law also permits the adoption of a bylaw amendment, approved by
shareholders, providing for the elimination of a director's liability for
monetary damages for any action taken or any failure to take any action unless
(1) the director has breached or failed to perform the duties of his office and
(2) the breach or failure to perform constitutes self-dealing, willful
misconduct or recklessness.

                  The bylaws of the Registrant provide for (1) indemnification

Item 22.          Undertakings.

                  (a)      The undersigned Registrant hereby undertakes:

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

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

                                    (ii) To reflect in the prospectus any facts
or events arising after the effective date of the registration statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement;

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

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

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

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

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

<PAGE>

the  prospectus  is  sent  or  given,   the  latest  quarterly  report  that  is
specifically incorporated by reference in the prospectus to provide such interim
financial information.

                  (d) (1) The undersigned Registrant hereby undertakes as
follows: that prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus
will contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

                      (2) The Registrant undertakes that every prospectus (i)
that is filed pursuant to paragraph (1) immediately preceding, or (ii) that
purports to meet the requirements of section 10(a) (3) of the Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

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

                  (f) The undersigned registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail 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.

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

Re:      Registration Statement on Form S-4
         Elverson National Bank

Ladies and Gentlemen:

         In connection with the proposed offering of up to 4,200,000 shares of
common stock, without par value (the "Common Stock"), by National Penn
Bancshares, Inc. (the "Company"), covered by the Company's Registration
Statement on Form S-4 (the "Registration Statement") filed on or about this date
with the Securities and Exchange Commission under the Securities Act of 1933, as
amended, we, as special counsel to the Company, have reviewed:

         (1) the Articles of Incorporation of the Company;

         (2) the Bylaws of the Company;

         (3) the resolutions, adopted July 16, 1998, by the Board of Directors
of the Company;

         (4)  the Registration Statement; and

         (5) such other documents, papers and matters of law as we have deemed
necessary under the circumstances.

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

         (1) 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 such Commonwealth.

         (2) The Common Stock covered by the Registration Statement has been
duly authorized and, when issued and sold pursuant to the terms described in the
Registration Statement, will be legally issued by the Company and fully paid and
nonassessable.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal
Matters" in the related 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 1993, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder.

                                                     Very truly yours,

Elverson National Bank

Elverson, PA  19520

                  Re:      Proposed Merger of Elverson National Bank with and
                           into National Penn Bank, a wholly-owned subsidiary
                           of National Penn Bancshares, Inc.

Ladies and Gentlemen:

                  We have acted as special counsel to Elverson National Bank, a
banking association organized under the national banking laws ("Elverson"), in
connection with the contemplated merger (the "Merger") of Elverson with and into
National Penn Bank, a national bank chartered under the National Banking Act
("NP Bank") and wholly-owned subsidiary of National Penn Bancshares, Inc., a
Pennsylvania corporation ("NPB"), pursuant to an Amended Agreement and Plan of
Merger dated as of July 21, 1998 (the "Merger Agreement").

                  All capitalized terms used herein, unless otherwise specified,
have the meanings assigned to them in the Proxy Statement/Prospectus (the "Proxy
Statement/Prospectus") forming a part of the Registration Statement filed on
Form S-4 by NPB with respect to the Merger (the "Registration Statement").

                  We have assisted in the preparation of the description of
certain federal income tax consequences of the Merger contained in the Proxy
Statement/Prospectus under the caption "THE MERGER"- - Certain Federal Income
Tax Consequences" (the "Tax Summary"). You have requested our opinion with
respect to the Tax Summary.

                  We have examined the Registration Statement and the Tax
Summary. In rendering our opinion, we have examined and relied upon the accuracy
and completeness of the facts, information, covenants and representations
contained in originals or copies, certified or otherwise identified to our
satisfaction, of the Merger Agreement, the Proxy Statement/Prospectus, the
Registration Statement and such other documents as we have deemed necessary or
appropriate as a basis for the opinion set forth below. We have assumed that the
Merger will be consummated in accordance with the Merger Agreement and as
described in the Proxy Statement/Prospectus. As described in the Tax Summary,
the consummation of the Merger is conditioned upon the delivery of opinions from
Elverson's and NPB's respective special counsels or independent certified public
accountants (the "Tax Opinions"). While we are not aware of any reason why the
Tax Opinions could not be delivered, we assume, for purposes of this opinion,
that the Tax Opinions will be delivered and that such Tax Opinions will be
supported by customary representations of the parties effective as of the
Effective Date of the Merger.

                  In rendering our opinion, we have considered the applicable
provisions of the Internal Revenue Code of 1986, as amended, Treasury
Regulations promulgated thereunder, pertinent judicial authorities, interpretive
rulings of the Internal Revenue Service and such other authorities as we have
considered relevant, in each case as in effect on the date hereof. Statutes,
regulations, judicial decisions and administrative interpretations are subject
to change at any time and, in some circumstances, with retroactive effect. A
material change in the authorities upon which our opinion is based could affect
our conclusions.

                  Based solely upon the foregoing, we are of the opinion that
the Tax Summary, although general in nature, is, in all material respects, a
fair and accurate summary of the principal United States federal income tax
consequences of the Merger under present law. As noted in the introductory
paragraph of the Tax Summary, the United States federal income tax consequences
with respect to any shareholder of Elverson will depend upon that shareholder's
particular circumstances and tax situation, and we express no belief with
respect to the accuracy or completeness of the Tax Summary as applied to any
shareholder in particular.

                  Except as set forth above, we express no opinion as to the
federal, state, local or foreign tax consequences of the Merger or of any
transactions related thereto. This opinion is solely for your benefit and is not
to be used, quoted, circulated or otherwise referred to without our express
written permission. Notwithstanding the previous sentence, we hereby consent to
the references to us under the captions "LEGAL OPINIONS" and "THE MERGER --
Certain Federal Income Tax Consequences" in the Proxy Statement/Prospectus
forming a part of the Registration Statement filed with the Securities and
Exchange Commission in connection with this

exhibit to the Registration Statement. In giving such consent, we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Securities Act of 1933.


                                            Very truly yours,
