Item 1.01 Entry into a Material Definitive Agreement

On November 3, 2009, Bryn Mawr Bank Corporation ("BMBC"), the parent company of The Bryn Mawr Trust Company ("BMT"), and First Keystone Financial, Inc. ("FKF"), the parent company of First Keystone Bank ("FKB"), entered into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which FKF will merge with and into BMBC (the "Merger"). Concurrent with the Merger, it is expected that FKB will merge with and into BMT in a two-step merger pursuant to which FKB will merge with and into a newly formed wholly-owned subsidiary of BMT which will then merge with and into BMT (collectively, the "Bank Merger").

Under the terms of the Merger Agreement, which is included as Exhibit 2.1 hereto and incorporated herein by reference, shareholders of FKF will receive 0.6973 shares (the "Exchange Ratio") of BMBC stock for each share of common stock they own plus $2.06 per share cash consideration ("Per Share Cash Consideration"), each subject to adjustment as described below. The Merger Agreement also provides that all options to purchase FKF stock which are outstanding and unexercised immediately prior to the closing ("Continuing Options") under FKF's Amended and Restated 1995 Stock Option Plan and Amended and Restated 1998 Stock Option Plan, in each case as amended, shall, subject to certain conditions and regulatory approvals, become fully vested and exercisable and be converted into fully vested and exercisable options to purchase shares of BMBC stock. The number of shares of BMBC stock to be subject to the Continuing Options shall be equal to 0.8204 ("Option Exchange Ratio") multiplied by the number of shares of FKF stock subject to the Continuing Options, subject to rounding. The exercise price per share of BMBC stock under the Continuing Options will be equal to the exercise price per share of FKF stock under the Continuing Options divided by the Option Exchange Ratio, subject to rounding.

The Exchange Ratio, Option Exchange Ratio and Per Share Cash Consideration are subject to adjustment in the event that "FKF Delinquencies," as defined in the Merger Agreement, are equal to or greater than $10,500,000 as of the month end prior to the closing. The delinquency thresholds and corresponding Exchange Ratio, Option Exchange Ratio and Per Share Cash Consideration adjustments are set forth on Exhibit C to the Merger Agreement.

The senior management of BMBC will remain the same following the Merger. At the closing of the Merger, BMBC and BMT will each expand the size of its board by one member and appoint Mr. Donald S. Guthrie as a director of each of BMBC and BMT in the class of directors whose terms expire at the 2011 annual meeting of shareholders of BMBC. At the end of his initial term, Mr. Guthrie will be re-nominated for an additional four-year term on each board, subject to the fiduciary duties of the board of directors and any applicable eligibility requirements set forth in BMBC's and BMT's articles of incorporation or bylaws. In the event that Mr. Guthrie is unable or unwilling to serve as a director of BMBC and BMT pursuant to the terms of the Merger Agreement, the board of directors of FKF (or the members of the Advisory Board (described below) after consummation of the Merger) shall substitute another member of the board of directors of FKF or FKB (or the Advisory Board if this occurs after the Merger), who shall be reasonably acceptable to BMBC and BMT, to serve as a member of the BMBC and BMT boards of directors in accordance herewith.

Upon the closing, BMT will form an advisory board (the "Advisory Board"), comprised of those members of FKF's and/or FKB's Boards of Directors immediately prior to the closing who do not become directors of BMBC and BMT and who agree in writing, at or prior to the closing, to serve on such Advisory Board immediately following the closing and execute a non-solicitation agreement in a form acceptable to BMBC and BMT.

Each of the directors of FKF has entered into a Voting Agreement, substantially in the form of Exhibit A of the Merger Agreement, dated as of November 3, 2009, with BMBC, pursuant to which each such director has agreed, among other things, to vote all shares of common stock of FKF owned by him or her in favor of the approval of the Merger at any shareholder's meeting to vote upon the Merger.

The Merger Agreement contains (a) customary representations and warranties of FKF and BMBC, including, among others, with respect to corporate organization, capitalization, corporate authority, third party and governmental consents and approvals, financial statements, and compliance with applicable laws,
(b) covenants of FKF to conduct its business in the ordinary course until the Merger is completed; (c) covenants of BMBC to use reasonable efforts to preserve intact its business organization and assets and maintain its rights and franchises, and (d) covenants of FKF and BMBC not to take certain actions during such period. FKF has also agreed not to (i) solicit proposals relating to alternative business combination transactions or (ii) subject to certain exceptions, enter into discussions concerning, or provide confidential information in connection with, any proposals for alternative business combination transactions.

Consummation of the Merger is subject to certain conditions, including, among others, approval of the Merger by shareholders of FKF, governmental filings and regulatory approvals and expiration of applicable waiting periods, accuracy of specified representations and warranties of the other party, effectiveness of the registration statement to be filed with the SEC to register shares of BMBC common stock to be offered to FKF shareholders, absence of a material adverse effect, receipt of tax opinions, and obtaining material permits and authorizations for the lawful consummation of the Merger and the Bank Merger.

The Merger Agreement also contains certain termination rights for FKF and BMBC, as the case may be, applicable upon the occurrence or non-occurrence of certain events, including: final, non-appealable denial of required regulatory approvals or injunction prohibiting the transactions contemplated by the Merger Agreement; if, subject to certain conditions, the Merger has not been completed by July 31, 2010; a breach by the other party that is not or cannot be cured within 30 days if such breach would result in a failure of the conditions to closing set forth in the Merger Agreement; FKF's shareholders failing to approve the transaction by the required vote; entry by the Board of Directors of FKF into an alternative business combination transaction; or the failure by the Board of Directors of FKF to recommend the Merger to its shareholders. If the Merger is not consummated under certain circumstances, FKF has agreed to pay BMBC a termination fee of $1.675 million.

The representations and warranties of each party set forth in the Merger Agreement have been made solely for the benefit of the other party to the Merger Agreement. In addition, such representations and warranties (a) are subject to materiality qualifications contained

in the Merger Agreement which may differ from what may be viewed as material by investors, (b) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement, and (c) may have been included in the Merger Agreement for the purpose of allocating risk between FKF and BMBC rather than establishing matters as facts. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the parties or their respective businesses.

The schedules to the Merger Agreement have been omitted. The registrant hereby agrees to furnish supplementally a copy of any omitted schedules to the Securities and Exchange Commission (the "SEC") upon its request.
