On October 23, 2014, Bryn Mawr Bank Corporation (the “Corporation”) entered into a definitive Amendment (the “Amendment”) to that certain Agreement and Plan of Merger, dated as of May 5, 2014 (the “Agreement”), between the Corporation and Continental Bank Holdings, Inc. (“CBH”).

In order to achieve certain administrative efficiencies, the parties agreed in the Amendment for the closing of the merger under the Agreement to occur no earlier than January 1, 2015, and to extend to January 5, 2015 the initial date at which, if the merger of CBH with and into the Corporation pursuant to the Agreement, as amended, has not closed, either the Corporation or CBH may terminate the Agreement. No other terms of the Agreement have changed as a result of the Amendment.

The foregoing summary of the Amendment is not complete and is qualified in its entirety by reference to the complete text of the Amendment, which is attached as Exhibit 2.1 hereto and incorporated herein by reference in its entirety.

IMPORTANT INFORMATION REGARDING THE CONTINENTAL MERGER

The Corporation has filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-4 concerning the Merger (SEC File No. 333-196916). The Registration Statement, which includes a prospectus for the offer and sale of the Corporation’s common stock to CBH’s shareholders as well as a proxy statement for each of the Corporation and CBH for the solicitation of proxies with respect to approval of the Merger, was declared effective by the SEC on July 31, 2014 and the definitive combine prospectus and proxy statement was subsequently sent to shareholders of the Corporation and CBH. The Merger was approved by shareholders of the Corporation at a special meeting of the Corporation’s shareholders held on September 23, 2014 and by shareholders of CBH at a special meeting of CBH’s shareholders on September 16, 2014. The combined prospectus and proxy statement and other documents filed by the Corporation with the SEC contain important information about the Corporation, CBH and the Merger. We urge investors and each of the Corporation’s and CBH’s shareholders to read carefully the combined prospectus and proxy statement and other documents filed with the SEC, including any amendments or supplements also filed with the SEC. Investors and shareholders may obtain a free copy of the combined prospectus and proxy statement – along with other filings containing information about the Corporation – at the SEC’s website at http://www.sec.gov.
