TABLE OF CONTENTS

Because Bancorp Financial common stock is not publicly traded, it is difficult to determine how its fair value compares to the merger consideration.

Bancorp Financial common stock is not listed on any national securities exchange and is not quoted in any established public trading market. As a result, there is no active market for Bancorp Financial common stock, and its shares lack liquidity. This absence of market pricing makes it difficult to determine the fair value of Bancorp Financial common stock. The merger consideration was determined through arm’s-length negotiations between Old Second and Bancorp Financial and may not reflect the price at which Bancorp Financial common stock would trade in an active market, if one existed.

The market price of Old Second common stock after the merger may be affected by factors different from those currently affecting the market price of Old Second common stock and the business performance of Bancorp Financial.

The businesses of Old Second and Bancorp Financial differ in certain respects, and the results of operations and financial condition of the combined company following the merger may be influenced by factors different from those that currently affect each company on a standalone basis. While Old Second common stock is listed and publicly traded, there is no established public trading market for Bancorp Financial common stock. As a result, there is no historical market price for Bancorp Financial common stock, and its value has not been subject to the same public market forces as Old Second common stock. Consequently, the market price of Old Second common stock after the completion of the merger may be affected by new or different factors, including how the market evaluates the combined company’s performance, integration progress, and business prospects.
