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 subsidiary, Enterprise Bank & Trust (the “Bank”.) In addition, as of October 21, 2005, the Company owns 60% of Millennium Brokerage Group, LLC (“Millennum”) through its wholly-owned subsidiary, Millennium Holding Company, Inc. Millennium is headquartered in Nashville, Tennessee and operates life insurance advisory and brokerage operations from thirteen offices serving life agents, banks, CPA firms, property & 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, Bank (100% owned) and Millennium (60% owned). Acquired businesses are included in the consolidated financial statements from the date of acquisition. All material intercompany accounts and transactions have been eliminated. 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 month period ended March 31, 2006 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2006. 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, 2005. 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 July 14, 2005, the Financial Accounting Standards Board (“FASB”) issued an exposure draft for Accounting for Uncertain Tax Positions, an Interpretation of FAS No. 109, Accounting for Income Taxes. The proposed interpretation would clarify the accounting for uncertain tax positions in accordance with FAS 109. An enterprise would be required to recognize, in its financial statements, the best estimate of the impact of a tax position only if that position is probable of being sustained on audit based solely on the technical merits of the position. In evaluating whether the probable recognition threshold has been met, this proposed Interpretation would require the presumption that the tax position will be evaluated during an audit by taxing authorities. The term probable is used in this proposed Interpretation consistent with its use in FASB Statement No. 5, Accounting for Contingencies, to mean “the future event or events are likely to occur.” Individual tax positions that fail to meet the probable recognition threshold will generally result in either (a) a reduction in the deferred tax asset or an increase in a deferred tax liability or (b) an increase in a liability for income taxes payable or the reduction of an income tax refund receivable. The impact may also include both (a) and (b). This proposed Interpretation also would provide guidance on disclosure, accrual of interest and penalties, accounting in interim periods, and transition. The FASB comment period ended on September 12, 2005. The Company is waiting on the final decision related to this Interpretation by FASB and is presently unable to determine its overall impact on the Company’s consolidated financial statements or results of operations.

NOTE 2—EARNINGS PER SHARE

The following table shows the components of basic and diluted earnings per share for the periods indicated.

As of March 31, 2006 and 2005, 0 and 3,019 options, respectively, were excluded from the earnings per share calculation because their effect was anti-dilutive.

NOTE 3—SHARE-BASED COMPENSATION

The Company maintains a number of stock-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, 2005. Prior to fiscal 2006, the Company applied the intrinsic value-based method, as outlined in Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” (“APB No. 25”) and related interpretations, in accounting for stock options granted under these programs. Under the intrinsic value-based method, no compensation expense was recognized if the exercise price of the Company’s employee stock options equaled the market price of the underlying stock on the date of the grant. Accordingly, prior to fiscal year 2006, no compensation cost was recognized in the accompanying consolidated statements of income on stock options granted to employees, since all options granted under the Company’s share incentive programs had an exercise price equal to the market value of the underlying common stock on the date of the grant.

Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123R (“SFAS No. 123R”) “Share-based Payment.” This statement replaces SFAS No. 123, “Accounting for Stock-Based Compensation,” and supersedes APB No. 25. SFAS No. 123R requires that all stock-based compensation be recognized as an expense in the financial statements and that such cost be measured at the fair value of the award. This statement was adopted using the modified prospective method of application, which requires the Company to recognize compensation expense on a prospective basis. Therefore, prior period financial statements have not been restated. Under this method, in addition to reflecting compensation expense for new share-based awards, expense is also recognized to reflect the remaining service period of awards that had been included in pro forma disclosures in prior periods. SFAS No. 123R also requires that excess tax benefits related to stock option exercises be reflected as financing cash inflows instead of operating cash inflows. For the three months ended March 31, 2006 and 2005, the Company recognized a tax benefit of $37,000 and $249,000, respectively, related to the exercise of non-qualified stock options as a component of paid-in capital.

For the three months ended March 31, 2005, the following table includes the disclosures required by Statement 123R and illustrates the pro forma impact on net income and earnings per share as if SFAS 123R had been applied to all outstanding awards for that period. The impact of adopting SFAS 123R increased the compensation expense in the first quarter of 2006 by $13,000, before income taxes, and had less than $0.01 impact on basic and diluted earnings per share.

The Company awarded 3,850 and 3,000 options, respectively during the three months ended March 31, 2006 and 2005. The fair value of stock options granted in the quarters ended March 31, 2006 and 2005 is estimated on the date of grant using the Black-Scholes option pricing model with the following average assumptions:

Compensation expense related to restricted share units (“RSUs”) was $113,000 in the first quarter of 2006. As of March 31, 2006, the total unrecognized compensation expense related to non-vested stock awards, including restricted stock units, was $1,581,000 and the related weighted average period over which it is expected to be recognized is approximately 3.5 years.

NOTE 4—ACQUISITIONS

On March 22, 2006, the Company entered into an agreement to acquire Kansas City-based NorthStar Bancshares, Inc. (“NorthStar”) for $36 million in EFSC stock and cash with the precise mix to be determined at closing. NorthStar has nearly $200 million in banking assets and is headquartered in North Kansas City, Missouri. The transaction is expected to have minimal impact on 2006 earnings per share and be slightly accretive to earnings per share in 2007. Please refer to the Form 8-K filed by the Company on March 23, 2006 for more information. The transaction is expected to close in third quarter subject to approval by NorthStar’s shareholders and customary regulatory agencies.

NOTE 5—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Bank utilizes interest rate swap derivatives as one method to manage some of its interest rate risks from 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 the Bank to interest rate risk.

The Bank 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.

The decision to enter into an interest rate swap is made after considering the asset/liability mix of the Bank, the desired asset/liability sensitivity and by interest rate levels. Prior to entering into a hedge transaction, the Bank formally documents the relationship between hedging instruments and hedged items, as well as the risk management objective for undertaking the various hedge transactions.

The following is a summary of the Company’s accounting policies for derivative instruments and its activities under SFAS No. 149, SFAS No. 133 and DIG Issue G25.

Cash Flow Hedges – The Bank entered into interest rate swaps to convert floating-rate loan assets to fixed rates. The swap agreements provide for the Bank to pay a variable rate of interest equivalent to the prime rate and to receive a fixed rate of interest. Under the swap agreements the Bank is to pay or receive interest quarterly. Amounts to be paid or received under these swap agreements are accounted for on an accrual basis and recognized as interest income of the related asset. The net cash flows related to cash flow hedges decreased interest income on loans by $338,000 in the first quarter 2006 and increased interest income on loans by $20,000 for the same period in 2005. In addition, a $30 million swap under which the Bank received a fixed rate of 5.3425% matured in March 2006.

Cash flow hedges are accounted for at fair value. The effective portion of the change in the cash flow hedge’s gain or loss is reported as a component of other comprehensive income, net of taxes. The ineffective portion of the change in the cash flow hedge’s gain or loss is recorded in earnings on each quarterly measurement date. At March

31, 2006 and December 31, 2005, $50,000 and $(263,000), respectively, in deferred gains/(losses), net of tax, related to cash flow hedges were recorded in accumulated other comprehensive income. All cash flow hedges were effective, therefore, no gain or loss was recorded in earnings. The maximum term over which the Bank is hedging its exposure to the variability of future cash flows is approximately 1 month.

Fair Value Hedges - The Bank has entered into interest rate swap agreements with the objective of converting the fixed interest rate on brokered CDs to a variable interest rate. The swap agreements provide for the Bank to pay a variable rate of interest based on a spread to the three-month London Interbank Offer Rate (LIBOR) and to receive a fixed rate of interest equal to that of the brokered CD (hedged instrument.) Under the swap agreements the Bank is to pay or receive interest semiannually. Amounts to be paid or received under these swap agreements are accounted for on an accrual basis and recognized as interest expense of the related liability. The net cash flows related to fair value hedges increased interest expense on certificates of deposit by $157,000 and $56,000 during the first quarter of 2006 and 2005, respectively.

Fair value hedges are accounted for at fair value. At inception, each hedging transaction is evaluated against the eight criteria applicable to fair value hedges pursuant to paragraph 68 of SFAS No. 133. Based on our evaluation, the swaps qualify for the “shortcut method” under SFAS No. 133; therefore, no ineffectiveness is assumed. As a result, changes in the fair value of the swaps directly offset changes in the fair value of the underlying hedged item (i.e., brokered CDs). All changes in fair value are measured on a quarterly basis.

The Company paid broker placement fees by reducing the proceeds received from the issued CD. The fees did not affect the inception value of the interest rate swap. Placement fees are capitalized and amortized into interest expense over the life of the CD in a manner similar to debt issuance costs.

The following table summarizes the Bank’s derivative instruments at the periods indicated below.

The notional amounts of derivative financial instruments do not represent amounts exchanged by the parties, and therefore, are not a measure of the Bank’s credit exposure through its use of these instruments. The credit exposure represents the accounting loss the Bank 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, 2006 and December 31, 2005, in connection with our interest rate swap agreements we had pledged investment securities available for sale with a fair value of $5 million. At March 31, 2006 and December 31, 2005, we had accepted, as collateral in connection with our interest rate swap agreements, cash of $196,300.

NOTE 6—DISCLOSURES ABOUT FINANCIAL INSTRUMENTS

The 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 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 Bank uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At December 31, 2005, no amounts have been accrued for any estimated losses for these financial instruments. The contractual amount of off-balance-sheet financial instruments as of December 31, 2005 and 2004 is as follows:

(in thousands)	March 31, 2006		December 31, 2005

Commitments to extend credit	$	355,011	$	346,205
Standby letters of credit		29,826		28,013

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, 2006 and December 31, 2005, approximately $10.7 million and $10.5 million, 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. The 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 to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the 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, 2006.

NOTE 7—SEGMENT REPORTING

Management segregates the Company into three distinct businesses for evaluation purposes. The three segments are Banking, Wealth Management, and Corporate and Intercompany. The segments are evaluated separately on their individual performance, as well as, their contribution to the Company as a whole.

The majority of the Company’s assets and income result from the Banking segment. The Bank is a full-service commercial bank with four St. Louis locations and two locations in the Kansas City region.

The Wealth Management segment includes the Trust division of the Bank along with Millennium. The Trust division of the Bank 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 thirteen offices serving life agents, banks, CPA firms, property & casualty groups, and financial advisors in 49 states.

The Corporate and Intercompany segment includes the holding company and subordinated debentures. The Company incurs general corporate expenses and owns the Bank and a 60% controlling ownership of Millennium.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method.

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

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

Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995

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 Enterprise Financial Services Corp’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, including 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; all of which could cause Enterprise Financial Services Corp’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 the integration of our proposed acquisition of NorthStar, both 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.

In addition to the foregoing, readers should refer to the risk factors discussed in our Annual Report of Form 10-K for the year ended December 31, 2005. 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.

Introduction

The following discussion describes significant changes in the financial condition of the Company that have occurred during the first three months of 2006 compared to December 31, 2005. 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, 2006 compared to the three months ended March 31, 2005. 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, 2005.

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 of Form 10-K for the year ended December 31, 2005.

Management believes there have been no material changes to our critical accounting policies.

Results of Operations

Net income for the three months ended March 31, 2006 was $3.0 million, an increase of 22% compared to $2.4 million for the same period of 2005. Fully diluted earnings per share for the three months ended March 31, 2006 and 2005 were $0.28 and $0.23, respectively.

On March 23, the Company announced an agreement to acquire NorthStar Bancshares, Inc, a Kansas City-based commercial bank. Please refer to the Form 8-K filed by the Company on March 23, 2006 for more information and to Note 4 – Acquisitions included in this filing.

Financial Condition

Portfolio loans grew by $64 million – a 25% annualized growth rate from December 31, 2005 and were up $93 million or 10% from March 31, 2005. Deposits declined $75 million or 7% during the first quarter of 2006. The growth in loans and decline in deposits was primarily funded by excess liquidity in the form of Federal funds (“Fed funds”) sold and short-term Federal Home Loan Bank (“FHLB”) advances. Fed funds sold were $65 million at December 31, 2005 compared to $6.0 million at March 31, 2006. In addition, at December 31, 2005, the investment portfolio contained $40 million of short-term discount notes that matured in first quarter 2006 and were not replaced. Total assets were $1.3 billion at March 31, 2006 and December 31, 2005.

The growth in loans in the first quarter was strong in both of our primary markets and is in part a result of the addition of experienced relationship managers in both St. Louis and Kansas City. The Bank continues to experience strong loan and deposit pricing competition in both markets. We continue to monitor competitive trends and intend to remain disciplined in our pricing practices in order to maintain margins.

Historically, deposits decline in the first quarter due to seasonal cash demands of our deposit client base. In addition, $10 million of the decline was related to a Brokered CD that matured during the quarter and was not replaced. FHLB advances were $75 million at March 31, 2006, a $46 million increase over December 31, 2005. The new advances are short-term and have less than three-month terms. They are considered an attractive alternative to higher-priced certificates of deposit.

Net Interest Income

Net interest income is the primary source of the Company’s revenue. Net interest income is the difference between interest income on interest-earning assets, such as loans and securities, and the interest expense on interest-bearing deposits and other borrowings, used to fund interest-earning and other assets. The amount of net interest income is affected by changes in interest rates and by the amount and composition of interest-earning assets and interest-bearing liabilities. Additionally, net interest income is impacted by the sensitivity of the balance sheet to changes in interest rates, which factors in characteristics such as the fixed or variable nature of the financial instruments, contractual maturities, and repricing frequencies.

Net interest spread and net interest rate margin are utilized to measure and explain changes in net interest income. Interest rate spread is the difference between the yield on interest-earning assets and the rate paid for interest-bearing liabilities that fund those assets. The net interest rate margin is expressed as the percentage of net interest income to average interest-earning assets. The net interest rate margin exceeds the interest rate spread because noninterest-bearing sources of funds (net free funds), principally demand deposits and shareholders’ equity, also support interest-earning assets.

Changes in the fed funds rate have a direct correlation with changes in the prime rate, the underlying index for most of the variable rate loans issued by the Bank. Throughout 2005 and first quarter 2006, slightly less than two-thirds of the loan portfolio floated with the prime rate. Historically the Company has been asset-sensitive, which means assets generally re-price faster than liabilities. Therefore, the 15 consecutive fed funds rate increases since late 2004 by the Federal Open Markets Committee (“FOMC”) have had a positive influence on net interest income.

Net interest income (presented on a tax-equivalent basis) was $11.5 million for the three months ended March 31, 2006, compared to $10.7 million for the same period of 2005, an increase of 7.0%. Average interest-earning assets increased $131 million, or 13% to $1.2 billion for the quarter ended March 31, 2006 compared to $1.0 billion for the same period in 2005. For the quarter ended March 31, 2006, average interest-bearing liabilities increased $130 million, or 16% to $934 million compared to $804 million for the quarter ended March 31, 2005.

The net interest rate margin (on a tax-equivalent basis) was 3.99% for the first quarter of 2006, compared to 4.18% in the first quarter of 2005. The margin was negatively impacted by a refinement in the methodology of deferring direct loan origination costs. This subsequently resulted in additional amortization costs and reduced the loan yield and net interest rate margin by approximately 18 bp and 16 bp, respectively. Excluding this refinement, the net interest margin would have been 4.15% in the first quarter of 2006.

The repositioning of a portion of investment portfolio during second half of 2005 led to an increase in the yield on securities. The increase in cost of funds was primarily due to increases in money market and certificate of deposit rates given competitor pricing and the increasing interest rate environment.

For more information see the “Rate/Volume” discussion.

NOTE:

The change in interest due to both rate and volume has been allocated to rate and volume changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Provision for loan losses. The provision for loan losses in the first quarter of 2006 was $800,000, compared to $786,000 in the same quarter of 2005. Provision levels remained flat due to similar levels of loan growth and the company’s overall credit risk profile. The allowance for loan losses as a percentage of total loans was 1.31% at March 31, 2006 compared to 1.30% at both December 31, 2005 and March 31, 2005. Management believes that the allowance for loan losses is adequate.

Asset quality remains strong. Nonperforming loans were $1.4 million or 13 basis points of total loans at March 31, 2006 versus 32 basis points at March 31, 2005 and 14 basis points at December 31, 2005. At March 31, 2006, three relationships comprised the non-performing loans. At March 31, 2005, three relationships comprised $2.2 million, or 71% of the non-performing loans. The remaining non-performing loans represented four different relationships.

The following is a summary of the Company’s credit management policies and procedures.

The Company’s credit management policies and procedures focus on identifying, measuring, and controlling credit exposure. These procedures employ a lender-initiated system of rating credits, which is ratified in the loan approval process and subsequently tested in internal loan reviews and regulatory bank examinations. The system requires rating all loans at the time they are made, at each renewal date and as conditions warrant.

Adversely rated credits, including loans requiring close monitoring, which would normally not be considered criticized credits by regulators, are included on a monthly loan watch list. Other loans are added whenever any adverse circumstances are detected which might affect the borrower’s ability to meet the terms of the loan. This could be initiated by any of the following:

1)	delinquency of a scheduled loan payment,

2)	deterioration in the borrower’s financial condition identified in a review of periodic financial statements,

3)	decrease in the value of collateral securing the loan or,

4)	change in the economic environment in which the borrower operates.

Loans on the watch list require detailed loan status reports, including recommended corrective actions, prepared by the responsible loan officer every three months. These reports are then discussed in formal meetings with the Senior Credit Administration Officer, Chief Credit Officer and Chief Executive Officer of the Bank.

Downgrades of loan risk ratings may be initiated by the responsible loan officer, internal loan review, or the credit analyst department at any time. Upgrades of certain risk ratings may only be made with the concurrence of the Senior Credit Administration Officer, Chief Credit Officer and Loan Review Officer.

In determining the allowance and the related provision for loan losses, three principal elements are considered:

1)	specific allocations based upon probable losses identified during a monthly review of the loan portfolio,

2)	allocations based principally on the Company’s risk rating formulas, and

3)	an unallocated allowance based on subjective factors.

The first element reflects management’s estimate of probable losses based upon a systematic review of specific loans considered to be impaired. These estimates are based upon collateral exposure, if they are collateral dependent for collection. Otherwise, discounted cash flows are estimated and used to assign loss.

The second element reflects the application of our loan rating system. This rating system is similar to those employed by state and federal banking regulators. Loans are rated and assigned a loss allocation factor for each category that is consistent with our historical losses, adjusted for environmental factors. The higher the rating assigned to a loan, the greater the allocation percentage that is applied.

The unallocated allowance is based on management’s evaluation of conditions that are not directly reflected in the determination of the formula and specific allowances. The evaluation of the inherent loss with respect to these conditions is subject to a higher degree of uncertainty because they may not be identified with specific problem credits or portfolio segments. The conditions evaluated in connection with the unallocated allowance include the following:

	•	general economic and business conditions affecting our key lending areas;

	•	credit quality trends (including trends in nonperforming loans expected to result from existing conditions);

	•	collateral values;

	•	loan volumes and concentrations;

	•	competitive factors resulting in shifts in underwriting criteria;

	•	specific industry conditions within portfolio segments;

	•	recent loss experience in particular segments of the portfolio;

	•	bank regulatory examination results; and

	•	findings of our internal loan review department.

Executive management reviews these conditions quarterly in discussion with our entire lending staff. To the extent that any of these conditions is evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s estimate of the effect of such conditions may be reflected as a specific allowance, applicable to such credit or portfolio segment. Where any of these conditions is not evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s evaluation of the probable loss related to such condition is reflected in the unallocated allowance.

Based on this quantitative and qualitative analysis, provisions are made to the allowance for loan losses. Such provisions are reflected in our consolidated statements of income.

Noninterest Income

The ratio of noninterest income to total income rose to 26% in the first quarter of 2006 from 15% in the same period of 2005. This trend is expected to continue primarily as a result of the October 2005 acquisition of Millennium. Wealth Management revenue increased $2.1 million, or 174%, from $1.2 million in the first quarter of 2005 to $3.3 million for the same period of 2006. The increase includes $1.8 million of commission income earned by Millennium during the first quarter of 2006. Revenue from the Company’s Trust operations increased $337,000, or 28% over first quarter of 2005. The increase in Trust revenue was the result of additional client relationships combined with favorable market conditions and client mix. Trust assets under administration increased almost $108 million in the first quarter of 2006 to $1.5 billion. In the fourth quarter of 2005, $250 million of assets managed in a special common trust fund account were distributed to clients as called for by contract. After adjusting for this distribution, Trust assets under administration have increased almost $300 million since March 31, 2005.

Service charges on deposit accounts were basically unchanged year over year due to a rising earnings credit rate on commercial accounts, which was offset by increased account activity.

Noninterest Expense

Expense management remains a priority for the Company. Our efficiency ratio, which expresses non-interest expense as a percentage of net interest income and other income, was 61.0% for first quarter of 2006, improved from 62.4% in the first quarter of 2005. Excluding the refinement in the methodology of deferring direct loan origination costs, the efficiency ratio for the first quarter of 2006 would have been 62.2%.

Noninterest expenses increased from $7.7 million in the first quarter of 2005 to $9.3 million in the same quarter of 2006. Approximately $873,000 of the $1.6 million increase was related to the addition of Millennium (including amortization of intangibles.)

Approximately $345,000, or 57%, of the increase in employee compensation and benefits is related to Millennium. Excluding Millennium, employee compensation and benefits increased 5%, or $258,000. Growth in wealth management revenues increased commissions by $176,000. The remainder is due to salaries and benefits of new associates, annual merit increases, along with increases in medical and disability insurance costs.

The addition of Millennium contributed $41,000 to the increase in occupancy expense. The remaining occupancy increases were due to scheduled rent increases on various Company facilities along with expenses related to additional space at the Company’s Operation Center and related leasehold improvements.

Data processing expenses increased due to upgrades to the Company’s AS400, licensing fee increases for our core banking system as a result of our increased asset size and increased maintenance fees for various Company systems.

Furniture and equipment increases were due to the new St. Charles bank location, Millennium and the expansion of the Operations Center.

Other noninterest expense includes $463,000 for Millennium expenses (including $228,000 for amortization of intangibles.) The remaining increase in other noninterest expense is related to increases in travel, meals and entertainment, increases in mark to market adjustments for outstanding Stock Appreciation Rights (SARs) paid to the directors and deferred compensation plans along with increases in general operating expenses such as stationary and office supplies, postage and courier charges.

Minority Interest in Net Income of Consolidated Subsidiary

On October 21, 2005, the Company acquired a 60% controlling interest in Millennium. The Company records its 40% non-controlling interest in Millennium, related to Millennium’s results of operations, in minority interest on the consolidated statements of income.

Income Taxes

In first quarter of 2006, the Company recorded income tax expense of $1.7 million compared to $1.4 million for the same period of 2005. The effective tax rates for the first quarter of 2006 and 2005 were 36.0% and 36.5%, respectively.

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 Federal Home Loan Bank, the ability to acquire large and 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 the Bank 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 $15 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. Currently, the Company has $30 million of outstanding subordinated debentures as part of four Trust Preferred Securities Pools. These securities are classified as debt but count as regulatory capital and the related interest expense is tax-deductible, which makes them very attractive.

Investment securities are an important tool to the Company’s liquidity objective. As of March 31, 2006, the entire investment portfolio was available for sale. Of the $110 million investment portfolio available for sale, $21.5 million was pledged as collateral for public deposits, treasury, tax and loan notes, and other requirements. The remaining securities could be pledged or sold to enhance liquidity if necessary.

The Bank has a variety of funding sources (in addition to key liquidity sources, such as core deposits, loan repayments, loan participations sold, and investment portfolio sales) available to increase financial flexibility. At March 31, 2006, the Bank had $96 million available from the Federal Home Loan Bank of Des Moines under a blanket loan pledge, absent the Bank being in default of its credit agreement, and $177 million available from the Federal Reserve Bank under a pledged loan agreement. The Bank also has access to over $70 million in overnight federal funds lines purchased from various banking institutions. Finally, because the Bank plans to remain a “well-capitalized” institution, it has the ability to sell certificates of deposit through various national or regional brokerage firms, if needed.

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 $355 million in unused loan commitments as of March 31, 2006. While this commitment level would be very difficult to fund on a short term basis given the Company’s current liquidity resources, we know that the nature of these commitments are such that the likelihood of such a funding demand is very low.

The Company and Bank 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 Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank 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 Bank’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 Bank 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, 2006 and December 31, 2005, that the Company and Bank meet all capital adequacy requirements to which they are subject.

As of March 31, 2006 and December 31, 2005, the Bank was categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized” the Bank 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:

(in thousands)	At March 31, 2006			At December 31, 2005

Tier I capital to risk weighted assets		9.87	%		10.31	%
Total capital to risk weighted assets		11.11	%		11.55	%
Leverage ratio (Tier I capital to average assets)		9.06	%		8.75	%
Tangible capital to tangible assets		6.70	%		5.98	%
Tier I capital	$	110,564		$	107,538
Total risk-based capital	$	124,528		$	120,528

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 or price risks. 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 Bank’s Asset/Liability Management Committee and approved by the Bank’s Board of Directors are used to monitor exposure of earnings at risk. General interest rate movements are used to develop sensitivity as the Bank feels it has no primary exposure to a specific point on the yield curve. These limits are based on the Bank’s exposure to a 100 bp and 200 bp immediate and sustained parallel rate move, either upward or downward.

The following table represents the estimated interest rate sensitivity and periodic and cumulative gap positions calculated as of March 31, 2006.
