ENTERPRISE FINANCIAL SERVICES CORP AND SUBSIDIARIES
Notes to Consolidated Financial Statements

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The more significant accounting policies used by the Company in the preparation of the consolidated financial statements are summarized below:

Basis of Financial Statement Presentation
Enterprise Financial Services Corp (the “Company” or “EFSC”) is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis and Kansas City metropolitan markets through its banking subsidiaries, Enterprise Bank & Trust (“Enterprise”) and Great American Bank (“Great American”.) Enterprise also operates a loan production office in Phoenix, Arizona. The Company plans to open a de novo bank in Phoenix in the fourth quarter of 2008 subject to regulatory approval. In addition, the Company owns 100% of Millennium Brokerage Group, LLC (“Millennium”) through its wholly-owned subsidiary, Millennium Holding Company, Inc. Millennium is headquartered in Nashville, Tennessee and operates life insurance advisory and brokerage operations from fourteen offices serving life agents, banks, CPA firms, property and casualty groups, and financial advisors in 49 states.

The consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

The consolidated financial statements include the accounts of the Company, Enterprise, Great American, and Millennium. Acquired businesses are included in the consolidated financial statements from the date of acquisition. All material intercompany accounts and transactions have been eliminated. Any minority ownership interests are reported in our Consolidated Balance Sheets as a liability. The minority ownership interest of our earnings or loss, net of tax, is classified as “Minority interest in net income of consolidated subsidiary” in our Consolidated Statements of Income.

Operating results for the three months ended March 31, 2008 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2008. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007. Certain reclassifications have been made to prior year balances to conform to the current year presentation. Such reclassifications had no effect on previously reported consolidated net income or shareholders’ equity.

New Accounting Standards
On January 1, 2008, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 157, Fair Value Measurements, and SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 159 permits the Company to choose to measure eligible items at fair value at specified election dates. Unrealized gains and losses on items for which the fair value measurement option (“FVO”) has been elected are reported in earnings at each subsequent reporting date. The fair value option (i) may be applied instrument by instrument, with certain exceptions, thus the Company may record identical financial assets and liabilities at fair value or by another measurement basis permitted under generally accepted accounting principles, (ii) is irrevocable (unless a new election date occurs) and (iii) is applied only to entire instruments and not to portions of instruments. The effect of the re-measurement was reported as a cumulative-effect adjustment, which reduced opening retained earnings on January 1, 2008, by $365,000. Upon adoption, the Company elected to account for $23 million of state tax credit assets at fair value. See Note 9 – Fair Value Measurements for more information.

In March 2008, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities — an Amendment of FASB Statement No. 133. SFAS 161 expands disclosure requirements regarding an entity’s derivative instruments and hedging activities. Expanded qualitative disclosures that will be required under SFAS 161 include: (1) how and why an entity uses derivative instruments; (2) how derivative instruments and related hedged items are accounted for under SFAS 133, Accounting for Derivative Instruments and Hedging Activities, and related interpretations; and (3) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS 161 also requires several added quantitative disclosures in financial statements. SFAS 161 will be effective for the Company on January 1, 2009. Management is currently evaluating the effect that the provisions of SFAS 161 will have on the Company’s financial statements.

5


In December 2007, the FASB issued SFAS No. 141(R), Business Combinations — a replacement of FASB No. 141. SFAS 141R replaces SFAS 141, Business Combinations, and applies to all transaction and other events in which one entity obtains control over one or more other businesses. SFAS 141R requires an acquirer, upon initially obtaining control of another entity, to recognize the assets, liabilities and any non-controlling interest in the acquiree at fair value as of the acquisition date. Contingent consideration is required to be recognized and measured at fair value on the date of acquisition rather than at a later date when the amount of that consideration may be determinable beyond a reasonable doubt. This fair value approach replaces the cost-allocation process required under SFAS 141 whereby the cost of an acquisition was allocated to the individual assets acquired and liabilities assumed based on their estimated fair value. SFAS 141R requires acquirers to expense acquisition-related costs as incurred rather than allocating such costs to the assets acquired and liabilities assumed, as was previously the case under SFAS 141. Under SFAS 141R, the requirements of SFAS 146, Accounting for Costs Associated with Exit or Disposal Activities, would have to be met in order to accrue for a restructuring plan in purchase accounting. Pre-acquisition contingencies are to be recognized at fair value, unless it is a non-contractual contingency that is not likely to materialize, in which case, nothing should be recognized in purchase accounting and, instead, that contingency would be subject to the probable and estimable recognition criteria of SFAS 5, Accounting for Contingencies. SFAS 141R is expected to have an impact on the Company’s accounting for business combinations closing on or after January 1, 2009.

NOTE 2—DISPOSITIONS

Sale of Liberty Branch
As previously announced, on February 28, 2008, the Company sold its Enterprise banking branch located in Liberty, Missouri to Farmers Bank & Trust, NA of Great Bend, Kansas, an unaffiliated bank. Deposit liabilities of $7,358,000 were sold along with approximately $158,000 of fixed assets. Goodwill and core deposit intangibles related to Liberty of $97,000 and $269,000, respectively, were written off on the sale date. The pre-tax gain on the sale (after write-offs) was $579,000.

Pending Sale of Great American
As previously announced, on February 5, 2008, the Company executed an agreement to sell its Great American subsidiary to First Financial Bancshares, Inc. (“First Financial”), an unaffiliated bank holding company. Subject to standard terms and conditions, including regulatory approvals, the sale is expected to close in the second quarter of 2008.

In a related transaction, prior to the sale of Great American, Enterprise will purchase the assets, assume the deposit liabilities of the Great American Claycomo branch along with certain other assets and liabilities, and will merge that branch into Enterprise. First Financial will then purchase the Great American bank charter and its remaining DeSoto branch and operate a community bank under the Great American name based in DeSoto, Kansas. At March 31, 2008, the assets and liabilities of the Claycomo branch were approximately $160,000,000 and $134,000,000, respectively. The assets and liabilities of the DeSoto branch will be sold with the Great American charter for approximately $6,500,000. The shareholders’ equity of the Great American charter on the date of the sale will be $2,500,000, comprised of approximately $33,000,000 in assets and $31,000,000 in liabilities. These amounts are immaterial to the consolidated balance sheet and therefore, were not classified as held for sale on the March 31, 2008 consolidated balance sheet.

NOTE 3—EARNINGS PER SHARE

Basic earnings per share data is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution of earnings per share which could occur under the treasury stock method if contracts to issue common stock, such as stock options, were exercised. The following table presents a summary of per share data and amounts for the periods indicated.

Three months ended March 31,
(in thousands, except per share data) 2008 2007
Net income, as reported $ 3,563 $ 3,158
 
Weighted average common shares outstanding 12,441 11,835
Additional dilutive common stock equivalents   234     363
Diluted shares outstanding   12,675     12,198
 
Basic earnings per share $ 0.29 $ 0.27
Diluted earnings per share $ 0.28 $ 0.26

For the three months ended March 31, 2008 and 2007, approximately 342,000 and 6,000 common stock equivalents, respectively, were excluded from the earnings per share calculation because their effect was anti-dilutive.

NOTE 4—GOODWILL AND INTANGIBLE ASSETS

The tables below present an analysis of the goodwill and intangible activity for the periods presented.

NOTE 5—DISCLOSURES ABOUT FINANCIAL INSTRUMENTS

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At March 31, 2008, no amounts have been accrued for any estimated losses for these financial instruments.

Each bank issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest-rate risk in excess of the amounts recognized in the consolidated balance sheets.

The contractual amount of off-balance-sheet financial instruments as of March 31, 2008 and December 31, 2007 are as follows:

  March 31,       December 31,
(in thousands)  2008 2007
Commitments to extend credit  $       545,399 $       535,227
Standby letters of credit    35,594     36,464

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses and may require payment of a fee. Of the total commitments to extend credit at March 31, 2008 and December 31, 2007, approximately $71,800,000 and $61,200,000, respectively, represents fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each bank evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the bank upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the bank subsidiaries to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of each bank’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 1 month to 5 years at March 31, 2008.

NOTE 6—SEGMENT REPORTING

The segments are evaluated separately on their individual performance, as well as, their contribution to the Company as a whole. The Banking segment consists of two full-service commercial banks, Enterprise and Great American. The Wealth Management segment includes the Trust division of Enterprise, the state tax credit initiative, and Millennium. The Trust division provides estate planning, investment management, and retirement planning as well as consulting on management compensation, strategic planning and management succession issues. Millennium operates life insurance advisory and brokerage operations from fourteen offices serving life agents, banks, CPA firms, property & casualty groups, and financial advisors in 49 states. The Corporate segment includes parent-only matters and incurs general corporate expenses.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. If appropriate, these changes are reflected in prior year information presented below.

Following are the financial results for the Company’s operating segments.

NOTE 7—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Enterprise utilizes interest rate swap derivatives to manage its interest rate risks from certain recorded financial assets and liabilities. These derivatives are utilized when they can be demonstrated to effectively hedge a designated asset or liability and such asset or liability exposes Enterprise to interest rate risk. The accounting policies associated with derivative financial instruments are discussed further in Note 7 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

Enterprise accounts for its derivatives under SFAS No. 149, An Amendment of Statement 133 on Derivative Instruments and Hedging Activities and SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. These Standards require recognition of all derivatives as either assets or liabilities in the balance sheet and require measurement of those instruments at fair value through adjustments to other comprehensive income, current earnings, or both, as appropriate.

Fair Value Hedges
Previously, Enterprise entered into interest rate swap agreements to convert the fixed interest rate on certain CDs to a variable interest rate. At March 31, 2008, Enterprise had no outstanding fair value hedges. One swap with a notional amount of $10,000,000, under which Enterprise received a fixed rate of 2.90%, matured in February 2007. The net cash flows related to fair value hedges increased interest expense on certificates of deposit by $41,000 in the first quarter of 2007.

Non-Designated Hedges
Enterprise has entered into interest rate swap agreements with the objective of converting long-term fixed rates on certain loans to a variable interest rate. At March 31, 2008, Enterprise had outstanding three non-designated hedges with a notional amount of $12,337,000. The non-designated hedges and related loans are accounted for at fair value. All changes in fair value are measured on a quarterly basis. The net change in fair value of the hedge and related loans decreased interest income by $10,000 and $3,000 in the first three months of 2008 and 2007, respectively.

The swap agreements provide for Enterprise to pay a fixed rate of interest equal to that of the loan and to receive a variable rate of interest based on a spread to one-month LIBOR. Under the swap agreements Enterprise is to pay or receive interest monthly. The net cash flows related to these hedges increased interest income on loans by $3,900 and $0 in the first three months of 2008 and 2007, respectively.

The following table summarizes Enterprise’s derivative instruments at March 31, 2008 and December 31, 2007.

  March 31,            December 31,      
(in thousands)  2008        2007      
Non-Designated Hedges

Weighted average pay rate   6.65 %     8.31 %
Weighted average receive rate   5.22 %   7.60   %
Weighted average maturity in months   63     69  

The notional amounts of derivative financial instruments do not represent amounts exchanged by the parties, and therefore, are not a measure of Enterprise’s credit exposure through its use of these instruments. The credit exposure represents the accounting loss Enterprise would incur in the event the counterparties failed completely to perform according to the terms of the derivative financial instruments and the collateral held to support the credit exposure was of no value. At March 31, 2008 and 2007, Enterprise had not pledged securities or received collateral in connection with the interest rate swap agreement.

NOTE 8—SHARE-BASED COMPENSATION PLANS

The Company maintains a number of share-based incentive programs, which are discussed in more detail in Note 17 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2007. The share-based compensation expense that was charged against income was $453,000 and $314,000 for the three months ended March 31, 2008 and 2007, respectively.

The fair value of the stock options granted in the quarters ended March 31, 2008 and 2007 is estimated based on the date of grant using the Black-Scholes option pricing model with the following average assumptions.

  Three months ended March 31,

NOTE 9—FAIR VALUE MEASUREMENTS

Effective January 1, 2008, the Company adopted SFAS No. 157, Fair Value Measurements, for financial assets and financial liabilities. In accordance with Financial Accounting Standards Board Staff Position (FSP) No. 157-2, Effective Date of FASB Statement No. 157, the Company will delay application of SFAS 157 for non-financial assets and non-financial liabilities, until January 1, 2009. SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements.

SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

SFAS 157 requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, SFAS 157 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

  • Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

  • Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

  • Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality, the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. These valuation methodologies were applied to all of the Company's financial assets and financial liabilities carried at fair value effective January 1, 2008. 

12


Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 and Level 3 inputs. The Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things. Level 3 securities available for sale include a FNMA agency pool and a Federal Home Loan Mortgage Corporation pool.

Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

State tax credits held for sale. These assets are reported at fair value utilizing Level 2 inputs. The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits.

Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its fixed-rate loan swaps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Accounts payable and other accrued expenses in the consolidated balance sheets. Derivatives with positive fair value are included in Prepaid expenses and other assets in the consolidated balance sheets.

The following table summarizes financial instruments measured at fair value on a recurring basis as of March 31, 2008, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

  Level 1      Level 2      Level 3      Total Fair

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Loans held for sale. These loans are reported at the lower of cost or fair value. Fair value is determined based on expected proceeds based on sales contracts and commitments and are considered Level 2 inputs.

Impaired loans. Impaired loans are included as Portfolio loans on the Company’s consolidated balance sheet with amounts specifically reserved for credit impairment in the Allowance for loan losses. The fair value of impaired loans is based on underlying collateral. These assets are classified as Level 2.

Other Real Estate. These assets are reported at the lower of the loan carrying amount at foreclosure or fair value less estimated costs to sell. Fair value is based on third party appraisals of each property and the Company’s judgment of other relevant market conditions. These are considered Level 2 inputs.

The following table presents the financial instruments measured at fair value on a non-recurring basis as of March 31, 2008.

  Level 1      Level 2      Level 3      Total Fair
(in thousands)  Input  Input Input Value
Loans held for sale $             - $ 3,422   $ - $ 3,422

Other real estate    -     7,736   -   7,736
Total $ - $      20,465 $ - $      20,465

Certain non-financial assets and non-financial liabilities measured at fair value on a recurring basis include reporting units measured at fair value in the first step of a goodwill impairment test. Certain non-financial assets measured at fair value on a non-recurring basis include non-financial assets and non-financial liabilities measured at fair value in the second step of a goodwill impairment test, as well as intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. As stated above, SFAS 157 will be applicable to these fair value measurements beginning January 1, 2009.

Effective January 1, 2008, the Company adopted the provisions of SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities - Including an amendment of FASB Statement No. 115. At March 31, 2008, all state tax credits held for sale are being accounted for at fair value to better reflect the economic benefits of this asset class to the Company. For the quarter ended March 31, 2008, changes in the fair value of the state tax credits held for sale of $903,000 were reported in Gain on sale of tax credits in the consolidated statements of income. There were no valuation allowances related to the state tax credits held for sale that were impacted by the adoption of SFAS 159. Below is a summary of the impact of the initial implementation of the FVO.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Readers should note that in addition to the historical information contained herein, some of the information in this report contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements typically are identified with use of terms such as “may,” “will,” “expect,” “anticipate,” “estimate,” “potential,” “could”: and similar words, although some forward-looking statements are expressed differently. You should be aware that the Company’s actual results could differ materially from those contained in the forward-looking statements due to a number of factors, including: burdens imposed by federal and state regulation, changes in accounting regulation or standards of banks; credit risk; exposure to general and local economic conditions; risks associated with rapid increase or decrease in prevailing interest rates; consolidation within the banking industry; competition from banks and other financial institutions; our ability to attract and retain relationship officers and other key personnel and technological developments; and other risks discussed in more detail in Item 1A: “Risk Factors”, all of which could cause the Company’s actual results to differ from those set forth in the forward-looking statements.

Other factors that could cause results to differ from expected results include the acquisition of Millennium and Clayco, all of which could result in costs and expenses that are greater, or benefits that are less, than we currently anticipate, or the assumption of unanticipated liabilities.

Readers are cautioned not to place undue reliance on our forward-looking statements, which reflect management’s analysis only as of the date of the statements. The Company does not intend to publicly revise or update forward-looking statements to reflect events or circumstances that arise after the date of this report. Readers should carefully review all disclosures we file from time to time with the Securities and Exchange Commission which are available on our website at www.enterprisebank.com.

Introduction
The following discussion describes the significant changes to the financial condition of the Company that have occurred during the first three months of 2008 compared to the financial condition as of December 31, 2007. In addition, this discussion summarizes the significant factors affecting the consolidated results of operations, liquidity and cash flows of the Company for the three months ended March 31, 2008 compared to the same period in 2007. This discussion should be read in conjunction with the accompanying consolidated financial statements included in this report and our Annual Report of Form 10-K for the year ended December 31, 2007.

Critical Accounting Policies
The impact and any associated risks related to the Company’s critical accounting policies on business operations are discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” where such policies affect our reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

The Company’s consolidated financial position reflects material amounts of assets and liabilities that are measured at fair value. A substantial portion of securities available for sale and state tax credits held for sale are carried at fair value. The fair value of securities available for sale is based upon measurements from an independent pricing service, including dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data and other information. Fair value of tax credits held for sale is determined using an internal valuation model with observable market data inputs. Considerable judgment may be required in determining the assumptions used in certain pricing models, including interest rate, credit risk and liquidity risk assumptions. Changes in these assumptions may have a significant effect on values.

Information concerning recently issued accounting pronouncements, which are not yet effective, is included in Note 1. The Company does not expect any of the recently issued accounting pronouncements to have a material effect on its financial condition.

Except as described in Note 9 – Fair Value Measurements, management believes there have been no material changes to our critical accounting policies.

Executive Summary
Net income for the three months ended March 31, 2008 was $3.6 million, an increase of 13%, compared to $3.2 million for the same period in 2007. Fully diluted earnings per share for the three months ended March 31, 2008 were $0.28, an 8% increase from the first quarter of 2007.

  • Loan growth – Portfolio loans grew $85.0 million, or 21% annualized, from December 31, 2007 and were up $234.0 million, or 16%, from March 31, 2007. Compared to the first quarter of 2007, when loan growth was only $15.0 million (excluding Great American), the absence of many of the conduit and longer-term, fixed rate competitors along with the steeper yield curve resulted in substantially fewer payoffs during first quarter of 2008. In addition, gross loan originations were consistent with those of the fourth quarter of 2007. Loan pricing appears to be stabilizing as the financial markets are beginning to price to risk, rather than for volume. Loan growth was strong in both St. Louis and Kansas City. Merger and acquisition financing along with commercial real estate and construction were the primary drivers of the growth.

  • Deposit growth – Historically, during the first and second quarter we experience seasonal deposit runoff. However, during the first quarter of 2008, deposits increased nearly $6.0 million from December 31, 2007. Although, non interest-bearing deposits have declined approximately $46.0 million since December 2007, we have not lost any significant relationships and believe the decline is due to normal seasonal runoff and customers investing excess funds in higher yielding deposit instruments. This is further evidenced by the fact that increases in interest-bearing and money market accounts have more than offset the decrease in non-interest bearing accounts. Our treasury management pipelines are strong, therefore, we expect to experience increases in non-interest bearing deposits throughout the year. Total deposits grew $145.0 million, or 10%, from March 31, 2007. Throughout the quarter we utilized approximately $32.0 million net in short-term brokered certificates of deposit to fund shortfalls due to loan demand. Brokered deposits represented 8% of total average deposits at March 31, 2008.

  • Asset quality – Nonperforming assets totaled $17.0 million, or 0.83%, of total assets at March 31, 2008 versus 0.78% and 0.62% at December 31, 2007 and March 31, 2007, respectively. At March 31, 2008, nonperforming loans represented 0.54% of portfolio loans compared to 0.77% at December 31, 2007. The allowance for loan losses was $22.2 million, or 1.29%, of portfolio loans versus $21.6 million, or 1.32%, at the end of 2007. See Provision for loan losses and nonperforming loans below for more information.

  • Net Interest Rate Margin – The fully tax-equivalent net interest rate margin was 3.63% for first quarter of 2008 versus 3.86% for same period of 2007. The decline from 2007 was primarily due to the reduced benefit of free funds resulting from falling interest rates.

  • Branch Sales and Expansion – As part of our expansion effort, we plan to continue our strategy of operating relatively fewer offices with a larger asset base per office, emphasizing commercial banking and wealth management and employing experienced staff who are compensated on the basis of performance and customer service. As a result, on February 28, 2008, we sold the Enterprise branch in Liberty, Missouri for a pre-tax gain of $579,000. In addition, we have executed an agreement to sell the Great American bank charter along with the DeSoto, Kansas branch. Pending regulatory approvals, the Great American transaction should be completed in second quarter of 2008. See Note 2 – Dispositions for more information.

During 2007, we announced our intent to enter the Phoenix, Arizona market, initially with a loan production office and subsequently through an application to establish a new Arizona state bank charter. The Company’s Arizona CEO, Jack Barry, is actively recruiting additional team members and local investors/directors to serve the planned de novo bank. The loan production office located in Central Phoenix opened in the fourth quarter of 2007. Through March 2008, the loan production office has generated approximately $11.0 million of commercial and industrial and commercial real estate loans.

  • Wealth Management – We continue to diversify our sources of fee income. As part of our new tax credit brokerage initiative within our Wealth Management segment, during the first quarter of 2008, we reported $1.0 million of gains related to state tax credits held for sale. See Note 9 – Fair Value Measurements for more information.

Wealth Management revenue in the first quarter of 2008, including the tax credit brokerage activity increased $600,000, or 21%, from the same quarter of 2007. Revenue declines in Trust Advisory and Millennium were more than offset by increases in Trust Fiduciary and the tax credits. See Noninterest Income in this section for more information.

Net Interest Income
The Company is slightly asset sensitive, which means our assets generally re-price faster than our liabilities. As a result, continued federal funds (“fed funds”) rate decreases by the Federal Open Market Committee will generally cause our asset yields to decline. In response to the January 2008 fed funds decreases which in turn lowered the prime rate earned on many of our loans, we aggressively reduced deposits rates. In order for us to maintain our net interest rate margin at adequate levels, we will continue to reduce the cost of our short term and maturing funding sources to respond to the impact of any additional interest rate decreases, while maintaining a competitive position within our market. The rapidity and severity of those rate cuts will have some impact on our ability to mitigate the effects of these cuts in the short-term.

Net interest income (on a tax-equivalent basis) was $16.4 million for the three months ended March 31, 2008 compared to $14.2 million for the same period of 2007, an increase of 16%. Total interest income increased $2.4 million while total interest expense increased $180,000.

Average interest-earning assets increased $323.0 million, or 22%, to $1.810 billion for the quarter ended March 31, 2008 compared to $1.487 billion in first quarter in 2007. Loans accounted for the majority of the growth, increasing by $320.0 million, or 23% to $1.689 billion. Interest income on loans increased $5.9 million from growth, but was offset by a decrease of $3.6 million due to the impact of rates, for a net increase of $2.3 million versus first quarter of 2007.

For the quarter ended March 31, 2008, average interest-bearing liabilities increased $327.0 million, or 26%, to $1.567 billion compared to $1.240 billion for the quarter ended March 31, 2007. The growth in interest-bearing liabilities resulted from a $194.0 million increase in interest-bearing core deposits, a $14.0 million increase in subordinated debentures, and a $119.0 million increase in borrowed funds including FHLB advances. We continue to meet loan funding shortfalls with FHLB advances and brokered certificates of deposit. For the first quarter of 2008, interest expense on interest-bearing liabilities increased $3.3 million due to growth while the impact of declining rates decreased interest expense on interest-bearing liabilities by $3.1 million versus first quarter of 2007.

The tax-equivalent net interest rate margin was 3.63% for the first quarter of 2008 compared to 3.86% for same period of 2007. The majority of the decline in the margin was due to the severity of the rate decreases by the Federal Open Market Committee during the latter half of 2007 and first quarter of 2008. While the margin declined from first quarter 2007, the net interest rate spread widened from 3.11% to 3.15% as a result of our ability to maintain our loan pricing relative to lower deposit costs.

Provision for loan losses and nonperforming loans
The provision for loan losses in the first quarter of 2008 was $2.3 million compared to $850,000 in the same quarter of 2007. The increase was due to stronger loan growth and adverse risk rating changes primarily in the residential builder portfolio as a result of the Company’s standard credit reviews. The allowance for loan losses as a percentage of total loans was 1.29% at March 31, 2008 compared to 1.32% at December 31, 2007 and 1.29% at March 31, 2007. Management believes that the allowance for loan losses is adequate.

During the first quarter of 2008, the Company had net charge-offs of $1.7 million, or 0.40% annualized. Almost 90% of the net charge-offs relate to three credits that had specific loss reserves totaling $1.5 million.

Nonperforming loans decreased $3.4 million from December 31, 2007. The decrease was due to moving nonperforming loans to Other real estate through foreclosure, principal reductions, and charging off deficiency balances. At March 31, 2008, nonperforming loans were $9.3 million, or 0.54%, of total loans. This compares to 0.77% at December 31, 2007 and 0.66% at March 31, 2007. Approximately $7.1 million, or 76%, of the nonperforming loans at March 31, 2008 is attributable to the soft residential housing markets in St. Louis and Kansas City.

19


Other real estate was $7.7 million at March 31, 2008 compared to $3.0 million at December 31, 2007 and $1.1 million at March 31, 2007. Approximately $1.8 million of the Other real estate is related to one relationship and consists of developed residential lots in St. Louis. An additional $1.8 million is related to one relationship consisting of commercial real estate. The remaining Other real estate represents several single family residences in St. Louis and Kansas City. We expect to sell approximately $1.9 million of the Other real estate in second quarter of 2008 based on signed sales contracts or contracts that are in process of being finalized.

Noninterest Income
Noninterest income increased $1.6 million, or 42% from the first quarter of 2007 compared to the first quarter 2008. The increase includes a $579,000 pre-tax gain on the sale of the Liberty branch, along with $1.0 million of gains related to state tax credit assets. In the first quarter of 2008, Wealth Management revenue from our Trust division and Millennium decreased $380,000 from the first quarter of 2007. Lower net client additions and reductions in asset values due to market performance drove lower revenue results in Trust Advisory. Higher producer payouts at Millennium also contributed to the decrease. These decreases were somewhat offset by increases from Trust Fiduciary. Our ratio of fee income to total revenue was 26% and 22% for the quarters ended March 31, 2008 and 2007, respectively.

Increases in Service charges on deposit accounts were primarily due to the declining earnings crediting rate on commercial accounts, which increased service charges collected. Fees related to nonsufficient funds and ATM usage also increased.

Noninterest Expense
Noninterest expenses were $13.8 million in the first quarter of 2008, an increase of $2.0 million, or 17%, from the same quarter in 2007. The Company’s efficiency ratio improved from 67% in first quarter of 2007 to 64% in the first quarter of 2008. The increase includes approximately $620,000 of incremental expenses related to the addition of Great American and $347,000 of increased compensation at Millennium due to the previously announced restructuring. Excluding these amounts, noninterest expenses increased $972,000 or 8%.

Excluding the incremental impact of Great American and Millennium, salaries and benefits increased $297,000, or 4.5%. The increase is primarily due to annual merit increases along with salaries and related benefits of new associates in various areas of our organization including banking units and other support areas.

Occupancy expense increases were due to scheduled rent increases on various Company facilities along with related leasehold improvements completed at the Operations Center and our Clayton, Missouri headquarters.

Approximately $61,000 of the increase in Data processing expenses was due to incremental costs related to Great American. The remaining increase was due to upgrades to the Company’s main operating system, licensing fee increases for our core banking system as a result of our increased asset size and increased maintenance fees for various Company systems.

Meals and entertainment decreased $143,000 due to less travel and controlled customer-related entertainment expenses.

21


The increase in Other noninterest expense includes $256,000 for FDIC insurance premiums resulting from the FDIC’s newly implemented rate structure along with a $379,000 increase in expenses related to nonperforming assets.

Income Taxes
The provision for income taxes was $2.0 million for the three months ended March 31, 2008 compared to $1.8 million for the same period in 2007. The effective tax rate for the three months ended March 31, 2008 was 35.4% compared to 36.2% for the same period in 2007. Federal tax benefits related to low income housing tax credits reduced the first quarter 2008 tax provision by $104,000.

Liquidity and Capital Resources
The objective of liquidity management is to ensure the Company has the ability to generate sufficient cash or cash equivalents in a timely and cost-effective manner to meet its commitments as they become due. Funds are available from a number of sources, such as from the core deposit base and from loans and securities repayments and maturities. Additionally, liquidity is provided from sales of the securities portfolio, lines of credit with major banks, the Federal Reserve and the FHLB, the ability to acquire brokered deposits and the ability to sell loan participations to other banks.

The Company’s liquidity management framework includes measurement of several key elements, such as the loan to deposit ratio, wholesale deposits as a percentage of total deposits, and various dependency ratios used by banking regulators. The Company’s liquidity framework also incorporates contingency planning to assess the nature and volatility of funding sources and to determine alternatives to these sources.

Strong capital ratios, credit quality and core earnings are essential to retaining cost-effective access to the wholesale funding markets. Deterioration in any of these factors could have an impact on the Company’s ability to access these funding sources and, as a result, these factors are monitored on an ongoing basis as part of the liquidity management process.

While core deposits and loan and investment repayments are principal sources of liquidity, funding diversification is another key element of liquidity management. Diversity is achieved by strategically varying depositor types, terms, funding markets, and instruments.

The parent Company’s liquidity is managed to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The parent Company’s primary funding sources to meet its liquidity requirements are dividends from subsidiaries, borrowings against its $16.0 million line of credit with a major bank, and proceeds from the issuance of equity (i.e. stock option exercises).

Another source of funding for the parent company includes the issuance of subordinated debentures. As of March 31, 2008, the Company had $56.8 million of outstanding subordinated debentures as part of eight Trust Preferred Securities Pools. These securities are classified as debt but are included in regulatory capital and the related interest expense is tax-deductible, which makes them a very attractive source of funding.

Each bank is subject to regulations and, among other things, may be limited in its ability to pay dividends or transfer funds to the parent Company. Accordingly, consolidated cash flows as presented in the consolidated statements of cash flows may not represent cash immediately available for the payment of cash dividends to the Company’s shareholders or for other cash needs.

Investment securities are also an important tool to the Company’s liquidity objective. As of March 31, 2008, the entire investment portfolio was available for sale. Of the $116.8 million investment portfolio available for sale, $77.2 million was pledged as collateral for public deposits, treasury, tax and loan notes, and other requirements. The remaining securities, excluding the FHLB capital stock, could be pledged or sold to enhance liquidity, if necessary.

The banks have a variety of funding sources available to increase financial flexibility. At March 31, 2008, under blanket loan pledges, absent being in default of their respective credit agreements, Enterprise had $87.5 million available from the FHLB of Des Moines and Great American had $9.5 million available from the FHLB of Topeka. In addition, Enterprise also had $208.0 million available from the Federal Reserve Bank under pledged loan agreements. Enterprise has access to over $70.0 million in overnight federal funds lines from various banking institutions, while Great American has over $20.0 million available in the form of overnight federal funds lines from various banking institutions. Finally, because both the banks are “well-capitalized”, they have the ability to sell certificates of deposit through various national or regional brokerage firms, if needed.

22


Over the normal course of business, the Company enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Company’s various risk management processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the Company’s liquidity. The Company has $545.4 million in unused loan commitments as of March 31, 2008. While this commitment level would be difficult to fund given the Company’s current liquidity resources, the nature of these commitments is such that the likelihood of funding them is very low.

The Company and its banking affiliates are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its banking affiliates must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The banking affiliate’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company and its banking affiliates to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. Management believes, as of March 31, 2008 and December 31, 2007, that the Company and its banking affiliates meet all capital adequacy requirements to which they are subject.

As of March 31, 2008 and December 31, 2007, both banking affiliates were categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized”, banks must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios.

The following table summarizes the Company’s risk-based capital and leverage ratios at the dates indicated:

At March 31,   At December 31,
(in thousands)  2008      2007
Tier I capital to risk weighted assets    9.15 %    9.32 % 
Total capital to risk weighted assets    10.36 %    10.54 % 
Leverage ratio (Tier I capital to average assets)    8.64 %      8.85 % 
Tangible capital to tangible assets    5.77 %    5.68 % 
Tier I capital  $  168,627   $ 164,957  
Total risk-based capital  $      190,877 $      186,549  

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the section captioned “Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995” included in Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Market risk arises from exposure to changes in interest rates and other relevant market rate or price risk. The Company faces market risk in the form of interest rate risk through transactions other than trading activities. Market risk from these activities, in the form of interest rate risk, is measured and managed through a number of methods. The Company uses financial modeling techniques to measure interest rate risk. These techniques measure the sensitivity of future earnings due to changing interest rate environments. Guidelines established by the Asset/Liability Management Committees and approved by the Company’s Board of Directors are used to monitor exposure of earnings at risk. General interest rate movements are used to develop sensitivity as the Company feels it has no primary exposure to a specific point on the yield curve. These limits are based on the Company’s exposure to a 100 basis points and 200 basis points immediate and sustained parallel rate move, either upward or downward.
