ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     On November 20, 2006, Stifel Financial Corp., a Delaware corporation
("Stifel"), and its wholly-owned subsidiary, FSFC Acquisition Co., a Missouri
corporation ("AcquisitionCo"), entered into an Agreement and Plan of Merger (the
"Merger Agreement") with First Service Financial Company, a Missouri corporation
("First Service"), pursuant to which Stifel will acquire First Service and its
wholly-owned bank subsidiary, FirstService Bank, by means of the merger (the
"Merger") of AcquisitionCo with and into First Service. The total consideration
payable by Stifel in the Merger for all of the outstanding shares of First
Service is approximately $37.9 million cash.

     The boards of directors of Stifel and First Service have each approved the
Merger Agreement. Consummation of the Merger is subject to a number of customary
conditions, including the receipt of all required regulatory approvals and
approval of the First Service shareholders. Upon consummation of its acquisition
of First Service and its wholly-owned bank subsidiary FirstService Bank, Stifel
will become a bank holding company and a "financial holding company", subject to
the supervision and regulation of The Board of Governors of the Federal Reserve
System.

     The Merger Agreement contains certain termination rights for Stifel and
First Service. The Merger Agreement further provides that upon termination of
the Merger Agreement under specified circumstances First Service may be required
to pay Stifel a termination fee of $1,400,000.

     Concurrently with the execution of the Merger Agreement, Stifel and
AcquisitionCo entered into a Shareholder Voting Agreement (the "Voting
Agreement") with all of First Service's current directors in which the
directors, in their capacities as First Service shareholders, have agreed to
vote their shares of First Service common stock in favor of the Merger Agreement
and the transactions contemplated thereby, including the Merger. Collectively,
the First Service directors own approximately 43% of the issued and outstanding
shares of First Service common stock. Approval of the Merger requires the
approval of the holders of two-thirds of the issued and outstanding shares of
First Service common stock.

     The foregoing summary of the Merger Agreement is not complete and is
qualified in its entirety by reference to the complete text of such document,
which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is
incorporated herein by reference in its entirety. The news release dated
November 20, 2006 announcing the transaction is included as Exhibit 99.1 to this
Current Report on Form 8-K and is incorporated herein by reference.
