SELLING SHAREHOLDERS

On May 26, 2006, we completed the merger of Legacy with and into our subsidiary, First National Bank of Pennsylvania. We are registering shares that the selling shareholders may acquire upon exercise of warrants or upon conversion of convertible debentures that we assumed in connection with the Legacy merger in order to enable the selling shareholders to sell, from time to time, shares of our common stock they acquire if they exercise their warrants or convert their debentures.

The table below supplements the table of selling shareholders contained in the “Selling Shareholders” sections of the Prospectus and the prior prospectus supplements. Where the name of a selling shareholder identified in the table below also appears in a table in the Prospectus or a prior prospectus supplement, the information set forth in the table below regarding that selling shareholder supersedes the information set forth in the Prospectus and the prior prospectus supplements.

Information regarding the selling stockholders may change from time to time and any modified information will be set forth in supplements to this prospectus supplement if and when necessary. Unless set forth below, to our knowledge, none of the selling shareholders has, or within the past three years has had, any material relationship with us or any of our predecessors or affiliates.

A selling shareholder listed below may from time to time offer and sell any or all of the selling shareholder’s securities under this Prospectus Supplement No. 3. Because the selling shareholder is not obligated to sell the shares of our common stock held by such selling shareholder, we cannot estimate the number of shares of our common stock that a selling shareholder will beneficially own after this offering. None of the selling shareholders listed below beneficially owns more than 1% of the outstanding shares of our common stock.
