On July 1, 2010, pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of April 25, 2010, among Stifel Financial Corp., a Delaware corporation (“Stifel”), PTAS, Inc., a Delaware corporation and a wholly-owned subsidiary of Stifel (“Merger Sub”), and Thomas Weisel Partners Group, Inc., a Delaware corporation (“Thomas Weisel Partners”), Merger Sub merged with and into Thomas Weisel Partners (the “Merger”), with Thomas Weisel Partners surviving the Merger.  As a result of the Merger, Thomas Weisel Partners is now a wholly-owned subsidiary of Stifel. 

Pursuant to the Merger Agreement, each outstanding share of Thomas Weisel Partners common stock was converted into the right to receive 0.1364 shares of Stifel common stock.  In addition, each outstanding Thomas Weisel Partners restricted stock unit was converted into the right to receive 0.1364 shares of Stifel common stock, and each outstanding Thomas Weisel Partners stock option was converted into the right to acquire 0.1364 shares of Stifel common stock, in each case in accordance with the existing vesting schedule and other terms thereof.  Further, pursuant to the Merger Agreement, each exchangeable share (the “Exchangeable Shares”) of TWP Acquisition Company (Canada), Inc., a corporation organized under the Ontario Business Corporation Act, and a subsidiary Thomas Weisel Partners’ (“Canadian Sub”), will remain outstanding following the Merger and has become exchangeable for 0.1364 shares of Stifel common stock. 

On July 1, 2010, Stifel issued a press release announcing the completion of the Merger and the other transactions contemplated by the Merger Agreement and the cessation of trading in Thomas Weisel Partners common stock as of the end of trading hours on the NASDAQ Global Market on June 30, 2010.

Item 5.03 Amendments to Articles of Incorporation or Bylaws.

            Concurrently with the completion of the Merger described above under Item 2.01, Stifel adopted and filed a Certificate of Designations, Preferences and Rights of Special Voting Preferred Stock (the “Certificate of Designations”) to create the share of special voting preferred stock that was issued to the trustee appointed under a voting and exchange trust agreement with respect to the Exchangeable Shares.  Except as otherwise required by law, the holder of record of the share of special voting preferred stock will have a number of votes equal to the number of votes that the holders of Exchangeable Shares that are not owned by Stifel or any person directly or indirectly controlled by or under common control with Stifel would be entitled to if all such Exchangeable Shares were exchanged by the holders thereof for shares of Stifel common stock, in each case for the election of directors and on all matters submitted to a vote of the stockholders of Stifel.  Except as otherwise required by law, the holder of record of the share of special voting preferred stock and the holders of Stifel common stock will vote together as one class on all matters.  The holder of the share of special voting preferred stock will not be entitled to receive dividends from Stifel and, in the event of any liquidation, dissolution or winding-up of Stifel, will not be entitled to receive any assets of Stifel.  At such time as there are no Exchangeable Shares outstanding not owned by Stifel or any person directly or indirectly controlled by or under common control with Stifel, and there are no shares of stock, debt, options or other agreements of Canadian Sub that could give rise to the issuance of any Exchangeable Shares to any person (other than Stifel or any person directly or indirectly controlled by or under common control with Stifel), the share of special voting preferred stock will be cancelled and retired without further action of Stifel, its Board of Directors or its shareholders and without the payment of any consideration in exchange for such cancellation.  The description of the special voting preferred stock is qualified in its entirety by reference to the Certificate of Designations, a copy of which is filed as Exhibit 3.1 and is incorporated by reference herein.
