**3. ACCOUNTING CHANGES**

In March 2004, the Financial Accounting Standards Board (“FASB”) reached a consensus on Emerging Issues Task Force Issue No. 03-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments” (“EITF 03-1”). EITF 03-1 provides guidance for determining when an investment is impaired and whether the impairment is other than temporary.  EITF 03-1 also incorporates into its consensus the required disclosures about unrealized losses on investments announced by the EITF in late 2003 and adds new disclosure requirements relating to cost-method investments.  The new disclosure requirements were effective for annual reporting periods ending September 15, 2004 and the new impairment accounting guidance was to become effective for reporting periods beginning after September 15, 2004.  In September 2004, the FASB delayed the effective date of EITF 03-1 for measurement and recognition of impairmentlosses until implementation guidance is issued.  

In June 2005, the FASB decided not to provide additional guidance on the meaning of other-than-temporary impairment, but directed the FASB staff to issue a FASB Staff Position (FSP) which will be re-titled FSP FAS 115-1, “The Meaning of Other-Than-Temporary Impairment and Its Applications to Certain Investments (“FSP FAS 115-1”). FSP FAS 115-1 will supersede EITF 03-1 and EITF Topic No. D-44, “Recognition of Other-Than-Temporary Impairment upon the Planned Sale of a Security Whose Cost Exceeds Fair Value.” FSP FAS 115-1 will replace guidance in EITF 03-1 on loss recognition with references to existing other-than-temporary impairment guidance, such as FASB Statement No. 115, Accounting For Certain Investments in Debt and Equity Securities (“SFAS 115”).  FSP FAS 115-1 will be effective for other-than-temporary impairment analysis conducted in periods beginning after September 15, 2005.  The Company has consistentlyfollowed the loss recognition guidance in SFAS 115, so the adoption of FSP FAS 115-1 is not expected to have a significant impact on the Company’s financial condition or results of operations.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets, an amendment of APB Opinion No. 29, “Accounting for Nonmonetary Assets” (“SFAS 153”).  SFAS 153 amends the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged and more broadly provides for exceptions regarding exchanges of nonmonetary assets that do not have commercial substance.   The provisions of SFAS 153 are effective for nonmonetary asset exchanges occurring in fiscal periods beginning after September 15, 2005. The Company does not expect the requirements of SFAS 153 to have a material impact on its financial position or results of operations.

In December 2004, Statement of Financial Accounting Standards (Statement) No. 123R, Share-Based Payment was issued, which sets accounting requirements for “share-based” compensation to employees, including employee-stock-purchase-plans (ESPPs) and provides guidance on accounting for awards to non-employees.  This Statement will require the Company to recognize in the income statement the grant-date fair value of stock options and other equity-based compensation issued to employees, but expresses no preference for a type of valuation model.  For the Company, this Statement is effective for the year beginning January 1, 2006.  On March 10, 2005, the Company’s Board of Directors adopted the Equity Incentive Plan (“Plan”), which provides for stock-based awards, subject to stockholder approval.  At the Company’s annual meeting on May 23, 2005, stockholders did not approve the Plan.  At present, no stock awards havebeen made from the Plan.  Therefore, the effect of the adoption of this statement on the Company cannot be determined currently. 

In September 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FASB Statement No. 3,” (“SFAS 154”). SFAS 154 changes the requirements for the accounting for and reporting of a change in accounting principle and also applies to all voluntary changes in accounting principle. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. 

**4. OFF BALANCE SHEET CREDIT COMMITMENTS**

In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States of America, are not included in its consolidated balance sheets. These transactions are referred to as “off balance-sheet commitments.” The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve elements of credit risk in excess of the amounts recognized in the consolidated balance sheet. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. 

The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Customers use credit commitments to ensure that funds will be available for working capital purposes, for capital expenditures and to ensure access to funds at specified terms and conditions. Substantially all of the Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Management assesses the credit risk associated with certain commitments to extend credit in determining the level of the allowance for loan losses. Commitments to extend credit totaled $4,042,000 at September 30, 2005 and $3,294,000 at December 31, 2004. 

Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The Company’s policies generally require that standby letters of credit arrangements contain collateral and debt covenants similar to those contained in loan agreements. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. Standby letters of credit totaled $9,615,000 at September 30, 2005 and $11,437,000 at December 31, 2004. At September 30, 2005, the outstanding standby letters of credit had a weighted average term of approximately one year. As of September 30, 2005and December 31, 2004, no liability for the fair value of the Company’s potential obligations under these guarantees has been recorded since the amount is deemed immaterial.

**5. CRITICAL ACCOUNTING POLICIES**

The Company’s accounting policies are integral to understanding the results reported. The Company’s accounting policies are described in detail in Note 1 to its consolidated financial statements included in its Annual Report on Form 10-K. The Company believes that of its significant accounting policies the allowance for loan losses may involve a higher degree of judgment and complexity. 

The allowance for loan losses provides coverage for probable losses inherent in the Company’s loan portfolio.  Management evaluates the adequacy of the allowance for loan losses each quarter based on changes, if any, in underwriting activities, the loan portfolio composition (including product mix and geographic, industry or customer-specific concentrations), trends in loan performance, regulatory guidance and economic factors.  This evaluation is inherently subjective, as it requires the use of significant management estimates.  Many factors can affect management’s estimates of specific and expected losses, including volatility of default probabilities, rating migrations, loss severity and economic and political conditions.  The allowance is increased through provisions charged to operating earnings and reduced by net charge-offs.

The Company determines the amount of the allowance based on relative risk characteristics of the loan portfolio.  The allowance recorded for commercial loans is based on reviews of individual credit relationships and an analysis of the migration of commercial loans and actual loss experience.  The allowance recorded for homogeneous consumer loans is based on an analysis of loan mix, risk characteristics of the portfolio, fraud loss and bankruptcy experiences, and historical losses, adjusted for current trends, for each homogeneous category or group of loans.  The allowance for loan losses relating to impaired loans is based on the loan’s observable market price, the collateral for certain collateral–dependent loans, or the discounted cash flows using the loan’s effective interest rate.

Regardless of the extent of the Company’s analysis of customer performance, portfolio trends or risk management processes, certain inherent but undetected losses are probable within the loan portfolio.  This is due to several factors including inherent delays in obtaining information regarding a customer’s financial condition or changes in their unique business conditions, the judgmental nature of individual loan evaluations, collateral assessments and the interpretation of economic trends.  Volatility of economic or customer-specific conditions affecting the identification and estimation of losses for larger non-homogeneous credits and the sensitivity of assumptions utilized to establish allowances for homogeneous groups of loans are among other factors.  The Company estimates a range of inherent losses related to the existence of the exposures.  The estimates are based upon the Company’s evaluation of imprecision riskassociated with the commercial and consumer allowance levels and the estimated impact of the current economic environment.

**6. ACQUISITIONS**

During February 2004, the Company purchased additional shares of Mid-America Bancorp, Inc., which increased its ownership to 56.2%.  As a result of the increased ownership, the Company obtained control of Mid-America.  At September 30, 2005, the Company’s ownership was 52.8%.  Effective February 29, 2004, the Company consolidated Mid-America in its financial statements as its investment is majority-owned by the Company.

Mid-America’s results of operations have been reflected in the Company’s consolidated statements of income beginning as of the acquisition date of February 29, 2004.  The following pro forma disclosures, including the effect of the purchase accounting adjustments, depict the results of operations as though the merger had taken place at the beginning of the nine month period ended September 30, 2004:

|--------|--------|----------------------------------------------------------------------------------------------------------------------------------|
|   | • | State Bank of Augusta   (“Augusta”), located in Augusta, Illinois;                                                     |

|   | •      Security State Bank of   Hamilton (“Hamilton”), located in Hamilton, Illinois, in which the Company   owns 92.75% (14,840 shares) of the outstanding voting stock; and                                                        |
|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|   | •      Mid-America Bancorp, Inc.   (“Mid-America”) (the sole shareholder of Heartland Bank (“Heartland”) located   in Leawood, Kansas), in which the Company owns 52.8% (68,000 shares) of the   outstanding voting stock. |

In addition, as of September 30, 2005, the Company had less than majority ownership interests in several additional banking organizations located in the Midwest and Southeast. Specifically, the Company owned the following percentages of the outstanding voting stock of these additional banking entities:

|   | •      36.5% of New Frontier   Bancshares, Inc. (“New Frontier”), the sole shareholder of New Frontier Bank   located in St. Charles, Missouri; |
|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|   | •      19.3% of NorthStar   Bancshares, Inc. (“NorthStar”), the sole shareholder of NorthStar Bank N.A.,   located in Liberty, Missouri;        |
|   | •      5% of GBC Bancorp, Inc.   (“GBC”), the sole shareholder of Gwinnett Banking Company, located in   Lawrenceville, Georgia; and            |
|   | •      5% of Integrity Bank,   which opened for business July 2004 in Jupiter, Florida.                                                                   |

In March 2005, the Company purchased 5,000 additional shares of Mid-America at a cost of $623,250, and in June 2005, another 15,000 shares at a cost of $2,023,500, which were portions of new stock issuances by Mid-America totaling 39,876 shares. Other shareholders also purchased newly issued shares during the nine months ended September 30, 2005, reducing the Company’s percentage ownership of Mid-America stock from 54.6% as of December 31, 2004 to 52.8% as of September 30, 2005.  On October 25, 2005, the Company purchased an additional 13,600 shares at a cost of $2,021,096.  This was also a portion of a new stock issuance by Mid-America totaling 14,412 shares and resulted in the Company’s percentage ownership increasing to 57.0% as of the date of the purchase.

In January 2005, the Company purchased 3,937 additional shares of New Frontier at a cost of $984,250, which was the Company’s pro-rata portion of a new stock issuance by New Frontier totaling 12,000 shares. In August 2005, the Company purchased an additional 3,314 shares of New Frontier at a cost of $828,500 from existing New Frontier stockholders who tendered their shares under New Frontier’s Shareholder Agreement.  This Agreement allows existing shareholders to purchase their pro-rata portion of the tendered shares, as well as their pro-rata portion of any tendered shares not purchased by other shareholders.  Shareholders other than the Company exercised their right to purchase 1,014 of the shares tendered.  As a result of the August 2005 purchase, the Company’s ownership of New Frontier increased to 36.5%.  In July 2005, the Federal Reserve had approved the Company increasing its ownership to 39.9% of New Frontier, and theCompany will consider additional acquisitions if additional shares are tendered for sale.

12

In June 2005, the Company purchased an additional 63,392 shares of NorthStar at a cost of $1,260,747 from existing NorthStar stockholders who have tendered their shares under NorthStar’s Shareholder Agreement.  This Agreement allows existing shareholders to purchase their pro-rata portion of the tendered shares, as well as their pro-rata portion of any tendered shares not purchased by other shareholders.  This purchase increased the Company’s ownership of NorthStar to 19.3% as of September 30, 2005.  The Company also has the opportunity to purchase additional shares as part of a new offering by NorthStar of 400,000 shares at $23.50 per share.  Although the May 2005 approval from the Federal Reserve of the shares purchased in June allows the Company to increase its ownership to a maximum of 21.0%, no decision has been made to acquire any additional NorthStar stock beyond the shares purchased in June.

In February 2005, MTSB opened a trust office in the St. Charles, Missouri location of the New Frontier Bank.

In 2004, Marine Bank began construction on a new principal bank building in Carthage, Illinois.  The original building commitment was $2,081,000, but contract changes and additions resulted in approximately $2,457,000 being expended as of September 30, 2005.  The construction was substantially complete as of September 30, 2005, and the facility opened for business on October 11, 2005.  

Farmers closed one of its branch locations in St. Joseph, Missouri, effective September 1, 2005.  This action was taken due to the limited activity at that branch. The Company expects the closure to result in enhanced growth for Farmers in that market through more efficient utilization of its resources and the ability to focus its customer service efforts at its two remaining locations in St. Joseph.  The customers will be serviced from the remaining two branches and deposit run-off is not anticipated.

During June 2005, Farmers entered into an employment contract with a licensed securities broker to provide, on behalf of the bank, personal financial advisory services, including the sale of non-deposit investment products through a national securities clearing house.  In the third quarter of 2005, Farmers entered into similar employment contracts with four other licensed securities brokers.  Compensation for each broker is based on a percentage of the commissions generated on the sale of the investment securities.  In addition, Farmers has also entered into advanced compensation agreements with the brokers, whereby the bank will prepay commissions in three installments over a period of six years.  The bank has recorded payments made under the agreements totaling approximately $750,000 in “other assets”, which is amortized to other noninterest expense as earned.  The brokers are responsible for repayment of a proportionate shareof the advance if the brokers are no longer employed by the bank during any period for which an advanced payment was made.  Additional advanced compensation payments are projected to be $375,000 in 2008 and 2011.

On August 15, 2005, the Company’s Board of Directors approved a Stock Repurchase Program authorizing the repurchase of up to 10%, or 196,368 shares of the Company’s common shares then outstanding. Repurchases will be made from time to time as market and business conditions warrant, in the open market, through block purchases and in negotiated private transactions. The timing of repurchases will depend on certain factors, including but not limited to market conditions and prices, the Company’s liquidity requirements and alternative uses of capital. Any repurchased shares will be held as treasury stock and will be available for general corporate purposes.  The Board established a limit of $10 million for stock repurchase pursuant to this program.  As of September 30, 2005, the Company had repurchased a total of 7,710 shares at a cost of $452,993.  An additional 6,095 shares were repurchased in October 2005 at a cost of $355,649. As of September 30, 2005, the Company had 1,974,930 shares issued, 1,955,970 shares outstanding and 18,960 shares in treasury.  Following the October 2005 purchase of 6,095 shares, the Company has 1,949,875 shares outstanding and 25,055 shares in treasury.

During the nine months ended September 30, 2005, the Company’s profit-sharing plan acquired 458 shares of the Company’s common stock at a cost of $26,266, which increased total holdings of the stock by the profit-sharing plan to 38,468 shares, at a cost of $1,267,840, as of September 30, 2005.  In addition, the profit-sharing plan acquired 141 shares of Company stock at a cost of $8,222 in October 2005.

On August 25, 2005, the Company participated in a private placement of $10 million of initially fixed and then floating interest rate trust preferred securities (the “Trust Preferred Securities”), through a newly formed Delaware trust subsidiary, Mercantile Bancorp Capital Trust I (the “Trust”).  The Trust Preferred Securities were issued and sold in a private placement exempt from registration under the Securities Act of 1933, as amended, pursuant to Section 4(2) of the Act, and may not be reoffered or resold in the United States absent registration or an exemption from the registration requirements.

13

The Trust Preferred Securities are redeemable at the Company’s option on any February 23, May 23, August 23 or November 23 on or after November 23, 2010.  In addition, the Trust Preferred Securities require quarterly distributions by the Trust to the holder of the Trust Preferred Securities at a rate of 6.10%, until November 23, 2015, at which time interest will convert to floating at three-month LIBOR plus 1.44%, reset quarterly until maturity.  The Trust simultaneously issued $310,000 of the Trust’s common shares of beneficial interest to the Company.  

The Trust used the proceeds of the sale of the Trust Preferred Securities to purchase from the Company the aggregate principal amount of $10,310,000 of the Company’s initially fixed and then floating rate junior subordinated debentures (the “Debentures”).  The $10,310,000 debentures are included in long-term borrowings on the balance sheet.  The Debentures were issued pursuant to an Indenture, dated August 25, 2005, between the Company and Wilmington Trust Company, as trustee.  Like the Trust Preferred Securities, the Debentures bear interest at a fixed rate, at 6.10% until November 23, 2015, after which the rate will reset on a quarterly basis to equal LIBOR plus 1.44%.  The interest payments by the Company will be used to pay the quarterly distributions payable by the Trust to the holders of the Trust Preferred Securities.  However, so long as no event of default, as described below, has occurred under the Debentures, theCompany may, from time to time, defer interest payments on the Debentures (in which case the Trust will be entitled to defer distributions otherwise due on the Trust Preferred Securities) for up to twenty (20) consecutive quarters.

The Debentures are subordinated to the prior payment of other indebtedness of the Company that, by its terms, is not similarly subordinated.  Although the Debentures will be recorded as a long-term liability on the Company’s balance sheet, for regulatory purposes the Debentures are treated as Tier 1 capital under regulatory capital guidelines issued by the Federal Reserve Board.

The Debentures mature on November 23, 2035, but may be redeemed at the Company’s option at any time on any February 23, May 23, August 23 or November 23  on or after November 23, 2010, or at any time upon certain events, such as a change in the regulatory capital treatment of Debentures, the Trust being deemed to be an investment company or the occurrence of certain adverse tax events.  

The Debentures may be declared immediately due and payable at the election of (a) the Debenture trustee, (b) the holders of 25% of the aggregate principal amount of outstanding Debentures, or (c) the holders of not less than a majority in liquidation amount of the Trust Preferred Securities then outstanding upon the occurrence of an event of default.  An event of default generally means: (1) default in the payment of any interest when due that continues unremedied for a period of thirty (30) days, except in the case of an election by the Company to defer payments of interest for up to twenty (20) consecutive quarters (which does not constitute an event of default); (2) a default in the payment of the principal amount of the Debentures at maturity; (3) a default in the payment of any interest following the deferral of interest payments by the Company for twenty (20) consecutive quarters; (4) a default in the Company’s performance, or breach, of anycovenant or warranty in the Indenture which is not cured within ninety (90) days; (5) the institution of any bankruptcy or similar proceedings by or against the Company; (6) the appointment of a receiver to a significant banking subsidiary for it or substantially all of its property in any liquidation, insolvency or similar proceeding with respect to it or substantially all of its property; or (7) the liquidation or winding up of the Trust, other than as contemplated in the Indenture.

The Company intends to use the proceeds of the offering for various corporate purposes, including, but not limited to, pursuit of the Company’s growth and operating strategy, retirement of debt, stock repurchases, and/or other general corporate purposes.  Through October 31, 2005, the Company had used the proceeds to repurchase shares of its common stock at a cost of $808,511, acquire additional shares of Mid-America at a cost of $2,021,096, and pay down $7,000,000 on its revolving line of credit with a correspondent bank.  

***Results of Operations Comparison of Operating Results for the Three Months Ended September 30, 2005 and 2004***

*Overview*.  Net income for the three months ended September 30, 2005 was $2,622,000, an increase of $1,000,000 or 61.7% compared with $1,622,000 for the same period in 2004. The primary factors contributing to the increase in net income were an increase in net interest income of $955,000 (primarily due to an increase in loan volume), an increase in noninterest income of $246,000 and a decrease in noninterest expense of $112,000.  The increase in net income was partially offset by an increase in provision for loan losses of $29,000, an increase in minority interest of $272,000, and an increase in provision for income taxes of $12,000.  Basic earnings per share (EPS) for the three months ended September 30, 2005 was $1.34 compared with $.83 for the same period in 2004.

This increase was due primarily to an increase in loan interest income of $2,748,000.  Average total loans for the three months ended September 30, 2005 increased $75,492,000, or 10.2% to $816,726,000 compared with $741,234,000 for the same period in 2004, while the average yield on total loans increased 81 basis points to 6.61% from 5.80% for the same period due to variable rate loans repricing upward and higher rates on new loans during the period.

This increase was due primarily to increases in interest expense on deposits of $1,623,000, on short-term borrowings of $117,000 and on long-term borrowings of $124,000.  Average total interest-bearing deposits for the three months ended September 30, 2005 increased $56,884,000, or 7.4% to $821,895,000 compared with $765,011,000 for the same period in 2004, while the average cost of funds on total interest-bearing deposits increased 64 basis points to 2.73% from 2.09% for the same period.

*Provision for Loan Losses.* Provisions for loan losses are charged against income to bring the Company’s allowance for loan losses to a level deemed appropriate by management. For the three months ended September 30, 2005, the provision increased by $29,000 to $451,000, compared with $422,000 for the same period in 2004.  The additional expense was primarily due to loan growth in the third quarter of 2005.  The allowance for loan losses at September 30, 2005 was $7,751,000, an increase of $636,000 compared to $7,115,000 at December 31, 2004.  As a percentage of total loans, the allowance for loan losses increased to .94% at September 30, 2005 compared to .92% as of December 31, 2004.  As of September 30, 2005, non-performing loans decreased to $4,113,000, or .50% of total loans, compared with $4,507,000, or .58% of total loans as of December 31, 2004.

*Noninterest Income.* Noninterest income for the three months ended September 30, 2005 increased $246,000 to $2,158,000 compared with $1,912,000 for the same period in 2004.  The increase in noninterest income was primarily due to increases in income on fiduciary activities, net gains on loan sales and income on equity method investments in common stock   The increase in income on fiduciary activities is attributable to growth in assets under management by the Company’s trust department.  The increase in net gains on loan sales reflects continued healthy activity in real estate mortgage refinancing, as long-term mortgage loan rates remained low despite a rising rate environment.  The increase in income on equity method investments in common stock is attributable to continued improvement in profitability for the Company’s equity method investments, New Frontier Bancshares, Inc. and NorthStar Bancshares, Inc.

Salaries and employee benefits decreased $327,000 or 7.6% for the three months ended September 30, 2005 to $3,976,000, from $4,303,000 for the same period in 2004.  This decrease was due primarily to a nonrecurring adjustment in September 2004 of the discount rate used to determine the liability for the salary continuation agreements the Company maintains for three executive officers.   The discount rate was reduced from 8.00% to 6.25%, and the corresponding adjustment increased 2004 salaries and employee benefits expense by approximately $626,000.  For the three months ended September 30, 2005, the elimination of the adjusting entry from the previous year, partially offset by cost of living increases in salaries and employee benefits, resulted in the net decrease of $327,000.  As a percent of average assets, annualized salaries and employee benefits decreased to 1.45% for the three months ended September 30, 2005, compared to 1.69% forthe same period in 2004. The Company had 311 full-time equivalent employees at September 30, 2005 and September 30, 2004. 

Professional fees increased $65,000 or 20.9% for the three months ended September 30, 2005 to $376,000, from $311,000 for the same period in 2004, primarily due to legal and accounting expenses associated with the Company’s filings with the Securities and Exchange Commission, as well as nonrecurring costs incurred due to the Company’s issuance of subordinated debentures.

Other noninterest expense increased $211,000 or 16.8% for the three months ended September 30, 2005 to $1,465,000, from $1,254,000 for the same period in 2004, primarily due to amortization of amounts earned under the advanced compensation agreements and other expenses associated with the employment of five licensed securities brokers at Farmers State Bank of Northern Missouri.

*Minority Interest*.  For the three months ended September 30, 2005, minority interest increased $272,000, to $302,000 compared with $30,000 for the same period in 2004, due to the improvement in Mid-America’s net income in 2005 which was partially due to a one-time tax adjustment of $157,000.  For the three months ended September 30, 2005, Mid-America’s pre-consolidated net income was $637,000, an increase of $592,000 compared to $45,000 for the same period in 2004, partially due to a one-time tax adjustment of $328,000.  During the three months ended September 30, 2005, due to recent steady profits, Mid-America increased to 34% from 18% the effective tax rate used to inventory its deferred tax asset, resulting in a nonrecurring reduction to tax expense of approximately $328,000.  The minority interest portion of this adjustment is approximately $157,000, which is an increase to minority interest for 2005.

*Provision for Income Taxes.*  The effective tax rate was 19.5% for the three months ended September 30, 2005 compared to 27.7% for the same period in 2004, due to the adjustment in September 2005 of the effective tax rate utilized to inventory the deferred tax assets of Mid-America.  Prior to the adjustment, Mid-America had inventoried its deferred tax assets at an effective tax rate of 18%, but management believes that Mid-America’s current and potential for future earnings is sufficient to warrant an increase in the rate to 34%, at September 30, 2005.  Without the nonrecurring adjustment, the effective tax rate for the Company would have been 29.5% for the three months ended September 30, 2005.

***Results of Operations Comparison of Operating Results for the Nine Months Ended September 30, 2005 and 2004***

*Overview*.  Net income for the nine months ended September 30, 2005 was $7,041,000, an increase of $1,401,000 or 24.8% compared with $5,640,000 for the same period in 2004. The primary factors contributing to the increase in net income were an increase in net interest income of $2,891,000 and noninterest income of $188,000.  This increase in net income was partially offset by increases in provision for loan losses of $458,000, noninterest expense of $660,000, minority interest of $447,000 and provision for income taxes of $113,000.  Basic earnings per share (EPS) for the nine months ended September 30, 2005 was $3.59 compared with $2.87 for the same period in 2004.

The Company’s annualized return on average assets was .88% for the nine months ended September 30, 2005, compared with 0.76% for the same period in 2004. The annualized return on average stockholders’ equity was 10.5% for the nine months ended September 30, 2005, compared to 9.2% for the same period in 2004.

*Net Interest Income*. For the nine months ended September 30, 2005, net interest income increased $2,891,000, or 12.4% to $26,124,000 compared with $23,233,000 for the same period in 2004. The increase was primarily due to the increased volumes and rates on loans, plus an increase in net interest margin, offset somewhat by increases in volume and rates on deposits and rates on borrowings. For the nine months ended September 30, 2005 and 2004, the net interest margin increased by 14 basis points to 3.52% from 3.38% while the net interest spread increased by 8 basis points to 3.22% from 3.14%, respectively.

Interest and dividend income for the nine months ended September 30, 2005 increased $7,185,000, or 19.8% to $43,511,000 compared with $36,326,000 for the same period in 2004.  This increase was due primarily to an increase in loan interest income of $7,279,000, partially offset by a decrease in securities interest income of $129,000.  Average total loans for the nine months ended September 30, 2005 increased $81,355,000 or 11.4% to $796,884,000 compared with $715,529,000 for the same period in 2004, while the average yield on total loans increased 64 basis points to 6.37%  from 5.73% for the same period. Average total investments for the nine months ended September 30, 2005 decreased $11,048,000 or 6.0% to $171,925,000 compared with $182,973,000 for the same period in 2004, while the average yield on investments increased 14 basis points to 3.85% from 3.71% for the same period.

Interest expense for the nine months ended September 30, 2005 increased $4,294,000, or 32.8% to $17,387,000 compared with $13,093,000 for the same period in 2004.  This increase was due primarily to increases in interest expense on deposits of $3,846,000 and interest expense on short-term borrowings of $297,000.  Average total interest-bearing deposits for the nine months ended September 30, 2005 increased $60,601,000, or 8.2% to $802,395,000 compared with $741,794,000 for the same period in 2004, while the average cost of funds on total interest-bearing deposits increased 49 basis points to 2.51% from 2.02% for the same period. Average total short-term borrowings for the nine months ended September 30, 2005 increased $7,320,000, or 48.1% to $22,539,000 compared with $15,219,000 for the same period in 2004, while the average cost of funds on  short-term borrowings increased 124 basis points to 2.84% from 1.60% for the same period.

*Provision for Loan Losses*. Provisions for loan losses are charged against income to bring the Company’s allowance for loan losses to a level deemed appropriate by management. For the nine months ended September 30, 2005, the provision increased by $458,000 to $1,680,000, compared with $1,222,000 for the same period in 2004.  The additional expense was primarily due to loan growth and additional net charge-offs in 2005.  The allowance for loan losses at September 30, 2005 was $7,751,000, an increase of $636,000 compared to $7,115,000 at December 31, 2004.

The increase in noninterest income was primarily due to increases in income from fiduciary activities, other services charges and fees and other noninterest income.  The increase in income on fiduciary activities is attributable to growth in assets under management by the Company’s trust department  The increase in other service charges and fees was due to enhanced efforts by the Company to assess fees for various ancillary customer and non-customer banking services.  The increase in other noninterest income was primarily due to increases in discount brokerage fees and credit card processing fees.

Salaries and employee benefits increased $338,000 or 2.9% for the nine months ended September 30, 2005 to $11,873,000, from $11,535,000 for the same period in 2004. This increase was primarily due to cost of living increases, additional salaries and benefits expense at Mid-America and an increase in post-retirement benefits expense, partially offset by a decrease in 2005 expense due to an adjustment of the salary continuation liability in 2004. Approximately $231,000 of the increase was attributable to Mid-America, which for 2004 included only the expenses for the period March 1, 2004 through September 30, 2004, due to the Company acquiring control on February 29, 2004, but for 2005 included the entire first nine months.   Another $203,000 of the increase was due to a nonrecurring adjustment of the discount rate from 7.25% to 5.50% used to determine the liability for post-retirement benefits. The 2004 adjustment to the salary continuation liabilitywas due to a reduction in September 2004 of the discount rate used to determine the liability for the salary continuation agreements the Company maintains for three executive officers.  The discount rate was reduced from 8.00% to 6.25%, and the corresponding nonrecurring adjustment increased 2004 salaries and employee benefits expense by approximately $626,000. As a percent of average assets, annualized salaries and employee benefits decreased to 1.49% for the nine months ended September 30, 2005, compared to 1.56% for the same period in 2004. The Company had 311 full-time equivalent employees at September 30, 2005 and September 30, 2004. 

Professional fees increased $120,000 or 12.3% for the nine months ended September 30, 2005 to $1,093,000, from $973,000 for the same period in 2004, primarily due to legal and accounting expenses associated with the Company’s filings with the Securities and Exchange Commission, as well as nonrecurring costs incurred due to the Company’s issuance of subordinated debentures.

22

Other noninterest expense increased $266,000 or 6.8% for the nine months ended September 30, 2005 to $4,177,000, from $3,911,000 for the same period in 2004, primarily due to the establishment of an investment securities brokerage operation at Farmers, as well as additional expense at Mid-America, which for 2004 included only the expenses for the period March 1, 2004 through September 30, 2004, due to the Company acquiring control on February 29, 2004, but for 2005 included the entire first nine months.

*Minority Interest*.  For the nine months ended September 30, 2005, minority interest increased $447,000, to $529,000 compared with $82,000 for the same period in 2004, due to the improvement in Mid-America’s net income in 2005, partially due to a one-time tax adjustment of $157,000 for Mid-America, increasing the minority interest.  For the nine months ended September 30, 2005, Mid-America’s pre-consolidated net income was $1,110,000, an increase of $984,000 compared to $126,000 for the same period in 2004, partially due to a one-time tax adjustment of $328,000 for Mid-America.

*Provision for Income Taxes.*  The effective tax rate was 25.8% for the nine-months ended September 30, 2005, compared to 29.3% for the same period in 2004, due to an adjustment in September 2005 of the effective tax rate utilized to inventory deferred tax assets of Mid-America.  Prior to the adjustment, Mid-America had inventoried the deferred tax assets at an effective tax rate of 18%, but management believes that Mid-America’s current and potential for future earnings is sufficient to warrant an increase in the rate to 34% at September 30, 2005.  Without the nonrecurring adjustment, the effective tax rate for the Company would have been 29.3% for the nine months ended September 30, 2005.

**Financial Condition  September 30, 2005 Compared to December 31, 2004**

*Loan Portfolio*. Total loans, including loans held for sale, increased $51,532,000 or 6.7% to $823,621,000 as of September 30, 2005 from $772,089,000 as of December 31, 2004. Approximately $27,000,000 of the growth in loans occurred at Mid-America during the first nine months of 2005, while the Company’s other subsidiaries experienced moderate growth.  At September 30, 2005 and December 31, 2004, the ratio of total loans to total deposits was 88.4%. For the same periods, total loans represented 74.0% and 74.2% of total assets, respectively.

*Nonperforming Assets*. Nonperforming assets consist of nonaccrual loans, loans 90 days or more past due, restructured loans, repossessed assets and other assets acquired in satisfaction of debts previously contracted.  It is management’s policy to place loans on nonaccrual status when interest or principal is 90 days or more past due. Such loans may continue on accrual status only if they are both well-secured and in the process of collection.

Total nonperforming loans decreased to $4,113,000 as of September 30, 2005 from $4,507,000 as of December 31, 2004, while total nonperforming loans and nonperforming other assets decreased to $4,761,000 as of September 30, 2005 from $5,084,000 as of December 31, 2004. These decreases reflect improved overall economic conditions in the Company’s markets, as well as strong performance in the agricultural sector as favorable weather conditions in the prior years’ growing seasons produced excellent crop yields. The ratio of nonperforming loans to total loans decreased to .50% as of September 30, 2005 from 0.58% as of December 31, 2004. The ratio of nonperforming loans and nonperforming other assets to total loans decreased to .58% as of September 30, 2005 from .66% as of December 31, 2004.

The 2005 growing season in the Company’s markets has been marked by near-drought conditions in certain areas which could have a negative impact on the Company’s nonperforming loan totals in the agricultural portfolio, and lead to additional charge-offs in the future.  However, crop insurance and federal agricultural subsidies could be mitigating factors for certain borrowers affected by poor crop yields.  The Company is monitoring these loans for indications of potential declines in credit quality, and will adjust the allowance for loan losses as necessary.

*Allowance for Loan Losses*. In originating loans, the Company recognizes that loan losses will be experienced and the risk of loss will vary with, among other things, general economic conditions, the type of loan being made, the creditworthiness of the borrower over the term of the loan and, in the case of a collateralized loan, the quality of the collateral for such loan. Management has established an allowance for loan losses which it believes is adequate to cover probable losses inherent in the loan portfolio. Loans are charged off against the allowance for loan losses when the loans are deemed to be uncollectible. Although the Company believes the allowance for loan losses is adequate to cover probable losses inherent in the loan portfolio, the amount of the allowance is based upon the judgment of management, and future adjustments may be necessary if economic or other conditions differ from the assumptions used by management in making thedeterminations.

Based on an evaluation of the loan portfolio, management presents a quarterly review of the allowance for loan losses to the board of directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. In making its evaluation, management considers the diversification by industry of the commercial loan portfolio, the effect of changes in the local real estate market on collateral values, the results of recent regulatory examinations, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers, the amount of charge–offs for the period, the amount of nonperforming loans and related collateral security, and the present level of the allowance for loan losses.

A model is utilized to determine the specific and general portions of the allowance for loan losses. Through the loan review process, management assigns one of six loan grades to each loan, according to payment history, collateral values and financial condition of the borrower. The loan grades aid management in monitoring the overall quality of the loan portfolio. Specific reserves are allocated for loans in which management has determined that deterioration has occurred. In addition, a general allocation is made for each loan category in an amount determined based on general economic conditions, historical loan loss experience, and amount of past due loans. Management maintains the allowance based on the amounts determined using the procedures set forth above.

The allowance for loan losses increased $636,000 to $7,751,000 as of September 30, 2005 from $7,115,000 as of December 31, 2004. Provision for loan losses was $1,680,000 and net charge-offs were $1,044,000 for the nine months ended September 30, 2005. The allowance for loan losses as a percent of total loans increased to .94% as of September 30, 2005 from .92% as of December 31, 2004. As a percent of nonperforming loans, the allowance for loan losses increased to 188.45% as of September 30, 2005 from 157.87% as of December 31, 2004.

*Securities*. The Company uses its securities portfolio to ensure liquidity for cash requirements, to manage interest rate risk, to provide a source of income, to ensure collateral is available for municipal pledging requirements and to manage asset quality.

The Company has classified securities as both available-for-sale and held-to-maturity as of September 30, 2005. Available-for-sale securities are held with the option of their disposal in the foreseeable future to meet investment objectives, liquidity needs or other operational needs. Securities available-for-sale are carried at fair value. Held-to-maturity securities are those securities for which the Company has the positive intent and ability to hold until maturity, and are carried at historical cost adjusted for amortization of premiums and accretion of discounts.

As of September 30, 2005, the fair value of the available-for-sale securities was $153,282,000 and the amortized cost was $153,315,000 for a net unrealized loss of $33,000.  The after-tax effect of this unrealized loss was $19,000 and has been included in stockholders’ equity. As of December 31, 2004, the fair value of the available-for-sale securities was $153,481,000 and the amortized cost was $151,928,000 for a net unrealized gain of $1,553,000, and an after-tax unrealized gain of $949,000. Fluctuations in net unrealized gain on available-for-sale securities are due primarily to increases or decreases in prevailing interest rates for the types of securities held in the portfolio.

As of September 30, 2005, the amortized cost of held-to-maturity securities was $16,167,000, a decrease of $3,723,000 from the December 31, 2004 amortized cost of $19,890,000.

*Other.*Other assets increased $1,181,000 to $4,150,000 at September 30, 2005, primarily due to payments made to the brokers at Farmers State Bank of Northern Missouri under the advanced compensation agreements that had not yet been earned and amortized to expense, as well as an increase in prepaid dealer reserve due to an increase in auto loans.

*Deposits*. Total deposits increased $57,859,000 or 6.6% to $931,286,000 as of September 30, 2005 from $873,427,000 as of December 31, 2004. Noninterest-bearing deposits increased $4,600,000 or 4.8% to $100,386,000 as of September 30, 2005 from $95,786,000 as of December 31, 2004, while interest-bearing deposits increased $53,259,000 or 6.8% to $830,900,000 as of September 30, 2005 from $777,641,000 as of December 31, 2004.  Of the increase in total deposits, approximately $33,100,000 was attributable to deposit growth at Mid-America, which served to fund the loan growth experienced at that subsidiary.

*Borrowings*. The Company utilizes borrowings to supplement deposits in funding its lending and investing activities. Short-term borrowings consist of federal funds purchased, securities sold under agreements to repurchase, U. S. Treasury demand notes and short-term advances from the Federal Home Loan Bank. Long-term borrowings consist of long-term advances from the Federal Home Loan Bank, advances on the revolving credit line with a correspondent bank and subordinated debentures. 

As of September 30, 2005, short-term borrowings were $17,061,000, a decrease of $4,324,000 from $21,385,000 as of December 31, 2004, and long-term borrowings were $57,720,000 as of September 30, 2005, an increase of $7,962,000 from $49,758,000 as of December 31, 2004.  The decrease in short-term borrowings as of September 30, 2005 coincided with an increase in noninterest-bearing deposits that occurred at the end of the quarter as the result of normal fluctuations in the balances of several large commercial depositors.  The additional liquidity produced by the increase in deposits, along with the proceeds from the issuance of subordinated debentures, allowed the Company to reduce short-term borrowings.  

The increase in long-term borrowings as of September 30, 2005 was primarily attributable to the Company’s issuance of subordinated debentures of $10,310,000 in August, 2005.  As of September 30, 2005, long-term FHLB borrowings totaled $37,475,000, with maturities ranging from the years 2006 to 2011 and interest rates ranging from 1.88% to 5.42%.  As of September 30, 2005, the correspondent bank revolving credit line totaled $9,935,000, and is due June 30, 2006, with interest payable quarterly at 1.5% below prime.  The interest rate at September 30, 2005 was 5.25%.  The revolving credit line balance increased $1,902,000 from the balance at December 31, 2004, and was utilized to partially fund the purchases of additional shares of New Frontier and NorthStar.

26

*Other.* Other liabilities increased $1,501,000 to $4,150,000 at September 30, 2005 primarily due to increased accruals for post-retirement benefits, salary continuation and bonus and profit-sharing due to increased profits for 2005.

**Liquidity and Capital Resources** 

*Liquidity*.  Liquidity management is the process by which the Company ensures that adequate liquid funds are available to meet the present and future cash flow obligations arising in the daily operations of the business in a timely and efficient manner. These financial obligations consist of needs for funds to meet commitments to borrowers for extensions of credit, funding capital expenditures, withdrawals by customers, maintaining deposit reserve requirements, servicing debt, paying dividends to shareholders, and paying operating expenses. Management believes that adequate liquidity exists to meet all projected cash flow obligations.

The Company achieves a satisfactory degree of liquidity through actively managing both assets and liabilities. Asset management guides the proportion of liquid assets to total assets, while liability management monitors future funding requirements and prices liabilities accordingly.

The Company’s most liquid assets are cash and due from banks, interest-bearing demand deposits, and federal funds sold.  The balances of these assets are dependent on the Company’s operating, investing, lending, and financing activities during any given period.  As of September 30, 2005, cash and cash equivalents totaled $55,052,000, an increase of $15,333,000 from $39,719,000 as of December 31, 2004.  This increase was partially the result of normal fluctuations in the Company’s cash flow requirements for funding loan growth and deposit withdrawals, but also attributable to the proceeds of the $10,310,000 subordinated debentures issue which had not been deployed for its intended purposes as of September 30, 2005.  In October 2005, the Company utilized the subordinated debentures proceeds to acquire additional shares of Mid-America and to pay down a portion of its correspondent bank line of credit, with the balance of cash andcash equivalents expected to return to normal levels.  The average balance of cash and cash equivalents for the nine months ended September 30, 2005 was $36,827,000, compared to $34,653,000 for the same period in 2004.

The Company’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayment, sales of loans, and capital funds. Additional liquidity is provided by bank lines of credit, repurchase agreements and the ability to borrow from the Federal Reserve Bank and Federal Home Loan Bank. 

In 2004, Marine Bank began construction on a new principal bank building in Carthage, Illinois.  The original building commitment was $2,081,000, but contract changes and additions resulted in approximately $2,457,000 being expended as of September 30, 2005.  The construction was substantially complete as of September 30, 2005 and the facility opened for business on October 11, 2005. The Company has no other signed commitments for purchase obligations or long-term obligations.

*Capital Resources*. Other than the issuance of common stock, the Company’s primary source of capital is net income retained by the Company. During the nine months ended September 30, 2005, the Company earned $7,041,000 and paid dividends of $354,000 to stockholders, resulting in a retention of current earnings of $6,687,000. During the year ended December 31, 2004, the Company earned $8,318,000 and paid dividends of $1,453,000 to stockholders, resulting in a retention of current earnings of $6,865,000.   As of September 30, 2005, total stockholders’ equity was $91,426,000, an increase of $5,444,000 from $85,982,000 as of December 31, 2004.  This increase was primarily due to the retention of earnings for the first nine months of 2005, offset by a reduction in accumulated other comprehensive income.  The reduction in accumulated other comprehensive income was primarily a result of the after-tax effect of the decline in marketvalue of the Company’s available-for-sale securities.

The Federal Reserve Board uses capital adequacy guidelines in its examination and regulation of bank holding companies and their subsidiary banks. Risk-based capital ratios are established by allocating assets and certain off-balance sheet commitments into four risk-weighted categories. These balances are then multiplied by the factor appropriate for that risk-weighted category. The guidelines require bank holding companies and their subsidiary banks to maintain a total capital to total risk-weighted asset ratio of not less than 8.00%, of which at least one half must be Tier 1 capital, and a Tier 1 leverage ratio of not less than 4.00%. As of September 30, 2005, the Company exceeds these regulatory capital guidelines. Likewise, the individual ratios for each of the Company’s bank subsidiaries also exceed the regulatory guidelines.

**Effect of Inflation and Changing Prices.**  

The condensed consolidated financial statements and related financial data presented herein have been prepared in accordance with accounting procedures generally accepted in the United States of America which require the measurement of financial position and operating results in terms of historical dollars, without considering the change in the relative purchasing power of money over time due to inflation.  The impact of inflation is reflected in the increased cost of the Company’s operations.  Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature.  As a result, interest rates generally have a more significant impact on a financial institution’s performance than do general levels of inflation.  Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.
