Re: Important Notice Concerning Your Rights Under the National Penn Bancshares, Inc. Capital Accumulation Plan

Dear Participant,

We are pleased to announce that we will be transferring the National Penn Bancshares, Inc. Capital Accumulation Plan’s recordkeeping service from ATR to Prudential Retirement, a business unit of Prudential Financial, effective March 7, 2007. Prudential has more than 75 years of experience managing retirement plans. With over $522 billion in retirement assets, they offer several important enhancements to our Plan, including a wider variety of investment options and a free asset-allocation program, as well as account information.

Converting Our Plan to Prudential

We have been working with retirement specialists from Prudential to arrange the successful transfer of your account balance from ATR. As part of this transfer there will be a period during which you will be unable to exercise your rights otherwise available under the Plan. This period is called a “blackout period”. The blackout period for the transfer is scheduled to begin on March 1, 2007 at 4:00 p.m. EST and is expected to end during the week of April 16, 2007.

During the blackout, your contribution and loan repayments will continue to be made to your account and you will be able to change the investment of your new contributions. You may also make a direct rollover from a previous employer’s qualified retirement plan. However, you will not be able to enroll in the plan for the first time, move your assets from one fund to another, take a distribution or request a loan during the blackout period.

Since activity is restricted during the blackout, you should review your current investments and make any changes you desire prior to March 1, 2007 at 4:00 p.m. EST.

Transfer of Assets to Prudential

ATR will send enrollment data to Prudential to set up your new account. This data includes information such as name, address, birth date, etc, along with your current investment allocation. Prudential will move your ATR investments to the Prudential investments using the following table. Your new contributions will also be allocated based upon this table.

On March 7, 2007, your account balance will be moved from investments held at ATR to the same or most comparable investment options at Prudential, based on the following table.
