                    NATIONAL PENN BANCSHARES, INC. TO ACQUIRE
                          NITTANY FINANCIAL CORPORATION


     Boyertown,  Pa. and State College,  Pa., September 7, 2005 -- National Penn
Bancshares,  Inc. (NASDAQ:  NPBC), the parent company of National Penn Bank, and
Nittany  Financial  Corporation,  (OTCBB:  NTNY),  the parent company of Nittany
Bank,  announced today that they have signed a definitive merger agreement under
which National Penn Bancshares would acquire Nittany  Financial in a transaction
valued at approximately $96.5 million.

     Nittany Financial is a financial  services company,  with $326.5 million in
assets, headquartered in State College, Centre County, Pennsylvania. Its Nittany
Bank  subsidiary  operates  four  community  offices in State College and one in
Bellefonte. Nittany Financial also has $310 million under management through two
of its  subsidiaries,  Vantage  Investment  Advisors,  LLC,  and  Nittany  Asset
Management, Inc.


                                      -1-

         Under the terms of the merger agreement, which was unanimously approved
by the boards of directors of both companies:


o    Nittany  Financial  shareholders will be entitled to exchange each share of
     Nittany  Financial common stock for 1.58 shares of National Penn Bancshares
     common  stock  or $ 42.43 in  cash.  The  five-for-four  stock  split  that
     National Penn  Bancshares  announced on August 24, 2005,  with an effective
     date of September 30, 2005,  results in an adjusted exchange ratio of 1.975
     shares of National Penn  Bancshares  common stock.  This exchange  ratio is
     subject  to further  adjustment  as set forth in the  definitive  agreement
     based on changes in the market  price of National  Penn  Bancshares  common
     stock.

o    Nittany  Financial  shareholders  may elect to receive cash,  National Penn
     Bancshares  common  stock  or a  combination  of  both  for  their  Nittany
     Financial  shares.   Additionally,   the  elections  of  Nittany  Financial
     shareholders are further subject to allocation procedures that are intended
     to result in the exchange of 30% of the Nittany  Financial shares for cash,
     and the remaining 70% exchanged for shares of National Penn common stock.

o    Options  to  purchase  shares of  Nittany  Financial  common  stock will be
     converted  into  options to  purchase  shares of National  Penn  Bancshares
     common stock.

o    Nittany Bank will ultimately retain its name as a division of National Penn
     Bank and initially  operate as a subsidiary  of National  Penn  Bancshares,
     Inc.  Two  non-management  members  of  Nittany  Financial's  board will be
     offered  seats on the  board  of  National  Penn  Bank.  Nittany  Financial
     President and CEO David Z. Richards Jr. will remain as president and CEO of
     Nittany Bank.  He also will join  National  Penn's  Leadership  Group,  the
     company's senior management team.

o    The existing  executive  management  team at Nittany  Financial has entered
     into employment  agreements with National Penn Bancshares and will continue
     to lead the combined company's business expansion efforts in Centre County,
     Pa.

         Upon completion of the merger,  National Penn expects to have assets in
excess of $5 billion  and to remain the seventh  largest  bank  holding  company
headquartered in Pennsylvania.


                                      -2-


         The transaction,  anticipated to close in the first quarter of 2006, is
subject to several  conditions  and  contingencies,  including  approvals by the
Federal  Reserve  Bank  and  the  Pennsylvania  Department  of  Banking  and the
affirmative  vote of the  shareholders  of  Nittany  Financial.  All  directors,
certain executive officers and greater-than-five percent shareholders of Nittany
Financial  (collectively  holding  approximately  40 percent of the  outstanding
shares of Nittany  Financial  common  stock ) have  agreed in letter  agreements
signed with National Penn to vote in favor of the merger.

         In a joint  announcement  made today by Wayne R. Weidner,  chairman and
CEO of National  Penn  Bancshares,  and Samuel J.  Malizia,  chairman of Nittany
Financial,  Weidner stated,  "Nittany is a financially  strong  institution with
excellent leadership and a similar culture and focus on the customer as National
Penn's.  They also have built a strong market position in a geographic area that
is one of the fastest  growing  regions in  Pennsylvania in terms of job growth.
The State College area also is  experiencing  growth in the  commercial and real
estate sectors -- two of National Penn's core strengths."

         Nittany  chairman,  Samuel J.  Malizia  said,  "With our success in our
marketplace and National Penn's financial success and excellent reputation, this
is a win-win for everyone. Our customers will benefit most, because they will be
served by the same  supportive  staff,  but will have access to a wider range of
services through the new parent company."

         Glenn E. Moyer,  president of National Penn,  said,  "This  transaction
gives us entry into an exciting  market with many  possibilities  for expansion.
It's  also  consistent  with  our  strategy  of  acquiring   highly   successful
organizations,  then allowing them to run according to their  business model and
grow with the additional resources we have to offer."

         David Z. Richards,  president and CEO of Nittany  Financial Corp. said,
"National Penn is unique from many other financial institutions,  with a history
of  providing  excellent  support to the  community  banks they  acquire,  while
allowing them to build on their entrepreneurial  spirit. They clearly understood
the  importance  of  maintaining  our growth  strategy and team of  professional
bankers. The message to our shareholders,  customers, community and employees is
that the same  Nittany  Bank,  with its core  values and  customer  focus,  will
continue to improve."

         There  are  2,270,442   shares  of  Nittany   Financial   common  stock
outstanding  and 90,909  options  outstanding  at an average  exercise  price of
$8.62.  Based on a 10-day  average  closing price per share for National Penn of
$25.75, the 70% stock and 30% cash blended acquisition price per share of $41.21
represents  24.8 times Nittany  Financial's  trailing twelve months earnings and
3.69  times  Nittany  Financial's  book  value  as of  June  30,  2005.  Nittany
Financial's  June 30, 2005  historical


                                      -3-


financial data has not been adjusted for recent option exercise.

         The merger is expected to be non-dilutive to National Penn  Bancshares'
earnings per share by the end of the first full year of combined operations, and
accretive in the second full year of combined  operations,  based on anticipated
revenue enhancements and cost savings. 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 Bancshares'  filings with the Securities and
Exchange Commission.

transaction to National Penn  Bancshares and Ryan Beck & Co. provided a fairness
opinion to Nittany  Financial.  Reed Smith LLP is legal counsel to National Penn
Bancshares, and Malizia Spidi Fisch, PC is legal counsel to Nittany Financial.
