NATIONAL PENN BANCSHARES, INC.

                                                   July 21, 1998

Dear Shareholder:

     We are pleased to  announce we have  executed a  definitive  agreement  for
National Penn Bancshares to acquire Elverson  National Bank.  Elverson is a $300
million bank headquartered in Elverson,  Pennsylvania, and operates nine offices
in Chester, Berks, and Lancaster Counties.

     The terms of the Agreement  call for the tax-free  exchange of 1.175 shares
of National Penn common stock for each share of Elverson common stock.  Based on
the $33.625 per share  closing  price of National  Penn common stock on July 17,
1998,  the value per share of  Elverson  National  Bank is  $39.51.  This  price
equates to 30.10 times Elverson's estimated trailing twelve months earnings, and
a multiple of 3.77 times Elverson's tangible book value as of June 30, 1998.

     The exchange  ratio is subject to  adjustment if the price of National Penn
Bancshares common stock declines to less than $30.38 as calculated by the 20 day
average of its stock price  during a period  ending 31 days prior to  Elverson's
shareholder  meeting to approve the transaction.  In that event, the ratio would
adjust to a ratio of 1.2 shares for each Elverson share. Should a decline exceed
20%,  Elverson would have the right to terminate the transaction if that decline
also was 5% more  than the  decline  in an index of stock  prices  of a group of
comparable  regional bank holding  companies  over the same time period,  unless
National Penn  Bancshares  chooses to increase the exchange ratio to 1.25 shares
for each Elverson  share. A decline in National  Penn's stock price in excess of
25% would permit Elverson to terminate the transaction.

     As of June 30, 1998,  Elverson had 2,597,995 million shares of Common Stock
outstanding and options for approximately 44,424 additional shares.

     As we previously  announced,  a 5-for-4  split of National Penn  Bancshares
common  stock is  currently  pending and will be  completed on July 31. Upon its
completion,  the  Agreement  provides for  proportionate  adjustment  of all the
exchange  ratio  provisions  so as to  preserve  the same  economic  terms as at
present.

     Upon  completion  of the  merger,  Elverson  will  operate as a division of
National  Penn Bank.  Elverson's  present  directors  will be  appointed  to the
divisional  board of  directors.  Two  members  of the  Elverson  Board  will be
mutually  selected to become  directors of National Penn Bancshares and National
Penn Bank.  Elverson's  president and CEO, Glenn E. Moyer, will become president
of the

Elverson National Bank Division and President of the Berks County and Montgomery
County  regions  of  National  Penn  Bank.  He will  also be an  Executive  Vice
President of National Penn Bank with additional corporate responsibilities.

     National  Penn  Bancshares  will have  assets of $2 billion  following  the
acquisition  which is subject to  regulatory  approval,  as well as  approval of
shareholders  of  Elverson  and  National  Penn.   Elverson's   directors,   who
beneficially own approximately 21% of the outstanding  shares of Elverson common
stock, have agreed to vote their shares for approval;  likewise, National Penn's
directors,  who beneficially own approximately 10% of the outstanding  shares of
National Penn's common stock, have agreed to vote their shares for approval.  We
anticipate  the  transaction  will close in either the fourth quarter of 1998 or
the first quarter of 1999. The transaction will be accounted for as a pooling of
interests  and is expected to be  accretive  to  National  Penn  earnings in the
second year.  As with any earnings  estimate  there are factors that could cause
the actual  results  to differ  materially,  such as the  factors  discussed  in
National Penn's 8-K filing with the SEC.

     Effective immediately,  we have rescinded our existing authorization to buy
back National Penn stock which authorized the repurchase of up to 530,000 shares
(or 662,500  shares when  adjusted for the stock split).  During 1998,  National
Penn  repurchased  approximately  233,267  shares  under the  authorization  (or
approximately 291,584 on a post-split basis).

     The  addition  of  Elverson  is highly  complementary  to  National  Penn's
existing  franchise  and will provide an excellent  opportunity  to increase our
market share in Chester  County,  southern  Berks  County and eastern  Lancaster
County.  Elverson's  longevity in Chester County and  deep-seated  commitment to
customer's needs is a natural fit with National Penn Bank's philosophy. National
Penn's existing Chester County retail delivery system (excluding  Phoenixville),
as well as its commercial lending office,  will be combined with and marketed as
Elverson  National  Bank, a division of National Penn Bank. We have been serving
the Chester County market for over 10 years with a full-service  loan office and
several branch  offices.  Chester County  continues to be a  fast-growing,  very
appealing region and this acquisition will enable us to aggressively  expand our
market presence.

     According to Elverson's  President,  Glenn E. Moyer,  "the affiliation with
National  Penn  offers  us  an  expanded  opportunity  to  enhance  our  product
offerings,  services,  and  delivery  channels to both  current and  prospective
customers. Positioning Elverson as a division of National Penn Bank will provide
our customers with the continued  benefit of a community bank philosophy,  which
has made us an outstanding performer. The expanded services and products

available  through this  affiliation will enable us to increase the expansion of
our customer base in many respects.  The increased  level of total  resources of
the merged companies will enable the Elverson  franchise to better service small
and  large  business  customers,  as  well as  individual  consumers  by  adding
electronic  banking  services,  trust  services and commercial  cash  management
products.  We have gained an excellent  reputation for our  willingness to serve
the local community with  competitive  products while  contributing to enhancing
the quality of life in the markets we service."

     We view this  affiliation  as an  excellent  strategic  fit for your  bank.
Although the price we are paying is high, the resulting  combination should bode
well for our successful and profitable growth in Chester County.

     You will be asked to vote on this  acquisition  later this  year.  Prior to
such vote,  you will  receive a proxy  statement  outlining in detail the entire
transaction.  At that time, we would ask that you give this proposal your utmost
attention.
