This presentation contains forward-looking information about National Penn Bancshares, Inc. that is intended to be covered
by the safe harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. Forward-
looking statements are statements that are not historical facts. These statements can be identified by the use of forward-
looking terminology such as “believe,” “expect,” “may,” “will,” “should,’’ “project,” “plan,’’ “goal,” “potential,” “seek,” “intend,’’ or
“anticipate’’ or the negative thereof or comparable terminology, and include discussions of strategy, financial projections,
guidance and estimates (including their underlying assumptions), statements regarding plans, objectives, expectations or
consequences of announced transactions, and statements about the future performance, operations, products and services of
National Penn and its subsidiaries. National Penn cautions readers not to place undue reliance on these statements.

National Penn’s business and operations are subject to a variety of risks, uncertainties and other factors. Consequently,
actual results and experience may materially differ from those contained in any forward-looking statements. Such risks,
uncertainties and other factors that could cause actual results and experience to differ from those projected include, but are
not limited to, the following: National Penn’s obligations under the U.S. Treasury’s TARP Capital Purchase Program; its ability
to obtain raise additional capital, to identify qualified consumers, businesses and growth opportunities; the ineffectiveness of
National Penn’s business strategy due to changes in current or future market conditions; the effects of competition, and of
changes in laws and regulations on competition, including industry consolidation and development of competing financial
products and services; interest rate movements; the performance of National Penn’s investment portfolio; disruption from
announced transactions, and resulting difficulties in maintaining relationships with customers and employees; challenges in
establishing and maintaining operations in new markets; and changes in consumer and business confidence. The foregoing
review of important factors should be read in conjunction with the risk factors and other cautionary statements included in
National Penn’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008, as well as in National Penn’s

Net Interest Margin Improving

*The core non-interest income numbers shown above are non-GAAP financial measures as they exclude other-than-
temporary impairment on CDO investments, net losses/(gains) from fair value changes on National Penn’s trust
preferred securities, and net losses on sales of investment securities. These amounts excluded from GAAP non-
interest income are as follows: 1Q09 - $7,785, $1,898, and $2,284; 2Q09 - $7,136, $(51), and $0; 3Q09 - $84,704,
$6,249, and $863, respectively. Management believes that the presentation of non-interest income excluding the
impact of the specified non-recurring items provides information that is comparable to prior periods, and therefore is
essential to a proper understanding of the financial information presented for National Penn.

Intention to Dispose of CDO Portfolio

l Continued deterioration in underlying issuers results
in additional reclassification of OCI into OTTI

l Deterioration in collateral/future cashflows available

l Structure of securities - lower rated tranches

l Deterioration in value not primarily market related

l Short term window to maximize current cash benefit
from a tax perspective

Overview of the Impact of Our Intention
to Dispose of CDO Portfolio

Overview of Tax Advantageous Timing

l Carry-back available for a portion of the loss
results in expected refund of previously paid
taxes approximately $27 million

l Remainder of loss available to offset future
taxable income

l Sales to take place beginning in 4Q09

Deferred Tax Asset

l Net of carry back available of approximately $27 million,
the net deferred tax asset is $72 million

l Deferred tax asset as an industry (and NPBC) increasing
due to items expensed for GAAP but not for tax, such as:

– Increased loan loss reserve with expense not recognized for tax
until charged off/disposed

– GAAP required FMV adjustments through OTTI and OCI that are
not tax deductible until securities sold

l Deferred tax asset evaluation more restrictive for
regulatory calculation as compared to GAAP
