Section 1 – Registrant’s Business and Operations

Item 1.01 Entry into Material Definitive Agreement.

     On December 31, 2007, Enterprise Financial Services Corp. (“Enterprise”) acquired all of the outstanding membership interests of Millennium Brokerage Group, LLC (“Millennium”), pursuant to a Membership Interest Purchase Agreement (Second Closing) (the “New Purchase Agreement”) dated December 31, 2007 by and among Enterprise, Millennium, Millennium Holding Company, Inc., a direct wholly-owned subsidiary of Enterprise (“MHC”), Millennium Holdings, LLC (“MBG Holdings”) and the other parties to the Original Purchase Agreement (as defined below).

     MHC originally acquired sixty percent of the membership interests of Millennium in October 2005 pursuant to a Membership Interest Purchase Agreement (the “Original Purchase Agreement”) dated October 13, 2005. Pursuant to the New Purchase Agreement, MHC has acquired the remaining forty percent membership interests from MBG Holdings and is now the sole member of Millennium.

     The Original Purchase Agreement provided for Enterprise’s staged acquisition of the remaining forty percent interest in Millennium at two closings, one to occur in March 2008 and the other in March 2010. The New Purchase Agreement amends the Original Purchase Agreement by providing for MHC’s immediate acquisition of the remaining forty percent interest in Millennium.

     The New Purchase Agreement also modifies the consideration specified in the Original Purchase Agreement for the remaining forty percent interest. The aggregate consideration for the remaining forty percent membership under the New Purchase Agreement interest will be between One Million Five Hundred Thousand Dollars ($1,500,000.00) and Nine Million Five Hundred Thousand Dollars ($9,500,000.00). At the closing of the New Purchase Agreement, MHC paid a down payment on the acquired membership interest to MBH Holdings in the amount of One Million Five Hundred Thousand Dollars ($1,500,000.00) in cash. The New Purchase Agreement also provides for an earnout pursuant to which Enterprise will pay MBG Holdings additional purchase consideration of up to Eight Million Dollars ($8,000,000.00) if Millennium produces minimum levels of Pre-Tax Income (as defined in the New Purchase Agreement) during 2008, 2009, 2010 and 2011. The earnout provision provides that Enterprise will pay MBG Holdings annual earnout payments of up to Two Million Dollars ($2,000,000.00) per year for each of 2008, 2009, 2010 and 2011 if Millennium achieves specified threshold levels of Pre-Tax Income in such respective years. The threshold and benchmark levels of Pre-Tax Income increase each year and the earnout payment for each year is determined based on Millennium’s performance for such year only. If the threshold earnout level for a year is not met, Enterprise will not be required to pay any additional consideration to MBG Holdings with respect to such year. All earn out payments by Enterprise will be in a combination of cash and Enterprise’s common stock, as described in Item 3.02 below.

     Under the New Purchase Agreement, certain employees of Millennium will be entitled to cash payments if Enterprise is subject to a Change of Control (as defined in the New Purchase Agreement) before December 31, 2011 and Millennium has at that time, on a cumulative basis, produced Pre-Tax Income equal to the cumulative thresholds for the earnout period through the date of the Change of Control. The aggregate change of control payments will not exceed One Million Dollars ($1,000,000.00) and each employee’s receipt of a change of control payment requires that such employee remain in the employ of the surviving company for up to three years after the Change of Control.

     The foregoing description of the transactions contemplated by the New Purchase Agreement is qualified in its entirety by reference to the New Purchase Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference.

Section 3 – Securities and Trading Markets

Item 3.02 Unregistered Sales of Equity Securities.

     Pursuant to the New Purchase Agreement, Enterprise may, in its discretion issue shares of its common stock as partial payment of any earnout consideration owed to MBG Holdings. If the earnout thresholds are achieved by Millennium and Enterprise elects to pay part of the earnout payments in the form of shares of its common stock, such shares will be valued at the average closing price during the period of thirty trading-days ending three days prior to the applicable earnout payment. The number of shares of Enterprise’s common stock to be issued in an earnout payment, if any, may be determined by Enterprise in its discretion, but with respect to each such payment may not exceed seventy percent (70%) of the consideration in such payment.

     All such shares will be issued by Enterprise in reliance upon an exemption from registration set forth in Section 4(2) of the Securities Act of 1933. The issuance and sale of the shares will be undertaken without general solicitation or advertising. Each recipient of shares will represent to Enterprise that, among other things, such person is acquiring the shares for investment purposes only and not with a view toward public distribution. As a result, the shares will be “restricted securities” and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. Certificates evidencing the shares will contain a legend stating the same.

Each Party agrees that such Party shall treat such payment as repayment of indebtedness on all Tax Returns filed by such Party.

ARTICLE 3
CONTINGENT PURCHASE PRICE; CHANGE OF CONTROL PAYMENT

3.01 Contingent Purchase Price.

(a) Upon the terms and subject to the conditions of this Section 3.01, Purchaser shall pay to Holdings Contingent Purchase Price with respect to the 2008, 2009, 2010 and/or 2011 Fiscal Years (collectively, the “Contingency Years”).

(b) (i) If the Company’s Pre-Tax Income for any Contingency Year equals or exceeds the Threshold Pre-Tax Income for such Contingency Year, on or prior to the later to occur of (A) the resolution any dispute pursuant to Section 3.01(d) or (B) the March 31 (a “Contingent Payment Date”) immediately following such Contingency Year, Purchaser shall pay to Holdings a “Contingent Payment.” In such event, the Contingent Payment shall be interpolated on a straight-line basis between the Threshold Contingent Payment Amount and the Maximum Contingent Payment Amount for such year as set forth in the chart below. With respect to the following Contingency Years, the terms “Threshold Pre-Tax Income,” “Target Pre-Tax Income,” “Threshold Contingent Payment” and “Maximum Contingent Payment” shall mean the respective amounts set forth below:

Contingency	Threshold Pre-	Threshold	Target Pre-Tax	Maximum
Year	Tax Income	Contingent	Income	Contingent
		Payment		Payment
2008	$2,340,000	$1,800,000	$2,600,000	$2,000,000
2009	$2,400,000	$1,600,000	$3,000,000	$2,000,000
2010	$2,450,000	$1,400,000	$3,500,000	$2,000,000
2011	$2,800,000	$1,400,000	$4,000,000	$2,000,000

6

          For purposes of clarification, the amount of the Contingent Payment with respect to any Contingency Year in which the Pre-Tax Income equals or exceeds such Contingency Year’s Threshold Pre-Tax Income shall equal the sum of (I) the Threshold Contingent Payment plus (II) product of (1) the excess of the Maximum Contingent Payment minus the Threshold Contingent Payment multiplied by (2) a fraction, (x) the numerator of which is the excess, if any, of the actual Pre-Tax Income minus the Threshold Pre-Tax Income and (y) the denominator of which is the excess of the Target Pre-Tax Income minus the Threshold Pre-Tax Income, as such amounts are determined with respect to the applicable Contingency Year. Notwithstanding the foregoing, in no event shall the fraction described in clause (2) above be greater than 1/1 and in no event shall the actual Contingent Payment with respect to any Contingency Year exceed Maximum Contingent Payment. The sum of all payments made by Purchaser pursuant to this Section 3.01(b) on all Contingent Payment Dates shall be the “Contingent Purchase Price.”

(ii) If the Company’s Pre-Tax Income for any Contingency Year does not equal or exceed the Threshold Pre-Tax Income for such Contingency Year, Holdings shall not be entitled to any Contingent Payment for such Contingency Year.

By way of example only, the following table sets forth the Contingent Payment with respect to the 2008 Contingency Year based on hypothetical amounts of Pre-Tax Income for such Contingency Year:

Hypothetical 2008 Pre-Tax	Hypothetical Contingent
Income	Payment on March 31, 2009
$2,000,000	$0.00
$2,340,000	$1,800,000.00
$2,500,000	$1,923,076.92
$2,700,000	$2,000,000.00

(c) Purchaser shall prepare unaudited financial statements of the Company for each Contingency Year (the “Post-Closing Financial Statements”) and deliver said Post-Closing Financial Statements to Holdings not later than three Business Days following EFSC’s filing of any form or report with the SEC, including without limitation a Current Report on Form 8-K, which contains EFSC’s consolidated earnings for any Contingency Year, but in no event later than February 28 following each Contingency Year. The Pre-Tax Income for each Contingency Year shall be based on the Post-Closing Financial Statements for such Contingency Year, each of which shall be prepared by Purchaser consistent with the books and records of the Company and in accordance with GAAP, as in effect during the period covered by the Audited 2004 Financial Statements and applied consistently with the Audited 2004 Financial Statements. Such delivery of the Post-Closing Financial Statements shall be accompanied by Purchaser’s calculation of the Contingent Payment, if any, payable with respect to such Contingency Year. Holdings shall have access to all of Purchaser’s working papers and other records relative to the preparation of the Post-Closing Financial Statements, and shall have reasonable access to the personnel and financial records of the Company for the purpose of determining any item reflected on the Post-Closing Financial Statements.

7

Each of the Post-Closing Financial Statements shall be conclusive and binding on the Parties unless the Holdings delivers an written notice of any objections (an “Objection Notice”) within thirty (30) days after Purchaser’s delivery thereof to Holdings. Any Objection Notice shall be in sufficient detail such that Purchaser can determine the nature, basis and, to the extent possible, amount of such objections. Purchaser and Holdings will use their good faith efforts to resolve any such objections themselves. In the event an Objection Notice is delivered by Holdings, Purchaser and Holdings shall meet (either in person or telephonically) within fifteen (15) days after delivery of the Objection Notice to attempt to resolve such objections. In the event that Purchaser and Holdings do not obtain a final resolution within forty five (45) days after delivery of any Objection Notice, then the CPA Firm shall resolve such dispute pursuant to the provisions of Section 3.01(d).

(d) In the event of any dispute between Purchaser and Holdings contemplated in Section 3.01(a), Deloitte & Touche LLP (the “CPA Firm”) shall resolve any objections which remain unresolved and determine any disputed Post-Closing Financial Statements in accordance with the provisions of this Agreement. Purchaser and Holdings shall deliver to the CPA Firm all financial information concerning the Company reasonably necessary to resolve the objections in such Objection Notice, including the disputed Post-Closing Financial Statements, a fully executed copy of this Agreement, the applicable work papers of Purchaser’s independent accounting firm and, to the extent permitted by such independent accounting firm, which permission Purchaser shall request, and each of Purchaser’s and Holdings’ applicable calculations, including calculations of the Pre-Tax Income or Contingent Payment.

8

               (ii) Deliver to Holdings such number of Restricted Purchaser Shares having an aggregate Closing Value equal to the remainder of the Contingent Payment.

(v) Notwithstanding any provision of this Section 3.01(f), Purchaser may amend the Company’s Operating Agreement or Articles of Formation in its sole and absolute discretion.

ENTERPRISE FINANCIAL COMPLETES PURCHASE OF

MILLENNIUM BROKERAGE GROUP

St. Louis, January 7, 2008. Enterprise Financial Services Corp (NASDAQ: EFSC) reported that it has purchased the remaining 40% minority interest in Millennium Brokerage Group LLC (MBG). Enterprise acquired 60% of Nashville, TN-based MBG for $15 million in October, 2005, with the acquisition of the remaining interest originally scheduled to occur in two stages in 2008 and 2010. Enterprise accelerated the acquisition timetable by purchasing the remaining 40% interest on December 31, 2007. MBG is now a wholly owned subsidiary of Enterprise Financial Services Corp.

Under terms of the restructured acquisition agreement, Enterprise acquired the remaining interest in MBG for $1.5 million plus subsequent annual payments of up to $2 million each year for four years contingent upon achievement by MBG of certain pre-tax earnings targets.

The acquisition of the remaining 40% of MBG membership interests was accelerated, according to Enterprise Financial CEO Kevin Eichner, “to accommodate a change in the Millennium partner compensation plan and equity incentives and to recognize the effects of the decline in Millennium’s margins on valuing the remaining ownership interests pursuant to the original buyout terms.”

As part of the new agreement, MBG partners will now earn a sliding scale percentage of net revenues produced annually by their respective offices. The net effect of the additional sales compensation, offset largely by significant reductions in overhead expenses, is not likely to have a meaningful impact on MBG’s contribution to EFSC’s 2008 earnings per share in relation to that of 2007.

Bill Zelenik, MBG President and CEO, commented, “Our new agreement enables us to more effectively recognize the distinctive sales contributions of key individuals and continue to provide a fair return to EFSC shareholders. I’m very pleased that our teams at MBG and Enterprise, working in partnership, were able to arrive at this new arrangement.”

Zelenik added, “Millennium’s value proposition to producers and insurance carriers is compelling. I am not aware of many firms that can match our nationwide reach, top quality products, personal service, technology and deep expertise in sophisticated wealth preservation and wealth transfer strategies. The new financial structure we now have in place enables us to continue to expand our business without missing a beat.”

Exhibit 99.1

MBG provides life insurance-based financial solutions to banks, CPA firms, broker-dealers and independent advisory firms through its offices across the U.S. As a wholly owned subsidiary, MBG includes its financial results as part of EFSC’s wealth management line of business. EFSC has applied to the Office of Thrift Supervision for a new national trust charter that will incorporate all of its wealth management businesses and MBG results will be reported under that charter once granted.

Enterprise Financial operates commercial banking and wealth management businesses in metropolitan St. Louis and Kansas City, and recently announced its intent to charter a new state bank in Phoenix, AZ. The Company focuses primarily on serving the needs of privately held businesses, their owners, executives and other professionals.
