PROSPECTUS SUMMARY This summary highlights information contained elsewhere in, or incorporated by reference into, this prospectus. Because this is a summary, it may not contain all information that may be important to you. Therefore, you should read the entire prospectus, our financial statements, including the related notes, and the other information that is incorporated by reference into this prospectus before making a decision to invest in our common stock. ALLEGIANT BANCORP, INC. We are the largest publicly-held bank holding company headquartered in the St. Louis metropolitan area. Our principal subsidiary, Allegiant Bank, offers full-service banking and personal trust services to individuals, businesses and municipalities in our market area. These services include commercial real estate, commercial business and consumer loans, checking, savings and time deposit accounts, wealth management and other fiduciary services, as well as other financial services, including mortgage banking, securities brokerage and insurance products. As of September 30, 2002, we reported, on a consolidated basis, total assets of $2.3 billion, loans of $1.6 billion and shareholders' equity of $160.4 million. This represents growth of 6.4%, 15.1% and 16.2%, respectively, when compared to our total assets, loans and shareholders' equity as of December 31, 2001. THE ST. LOUIS MARKET The St. Louis metropolitan area is the 18th largest metropolitan market in the United States with a population of approximately 2.5 million. The St. Louis area is home to 15 Fortune 1000 companies, including Anheuser-Busch Companies, Inc., Emerson Electric Co. and The May Department Stores Company. Over the past several years, a number of financial institutions in our market area have been acquired by larger regional or national out-of-town financial institutions. These acquisitions have included: Marshall & Ilsley Corporation's 2002 acquisition of Mississippi Valley Bancshares, Inc., Firstar Corporation's (now operating as U.S. Bancorp) 1999 acquisition of Mercantile Bancorporation Inc., Union Planters Corporation's 1998 acquisition of Magna Group, Inc. and NationsBank Corporation's (now operating as Bank of America Corporation) 1997 acquisition of Boatmen's Bancshares, Inc. We believe we have capitalized on opportunities created by this market consolidation and have built a strong, customer-friendly, community-focused banking franchise. KEY OPERATING STRENGTHS We believe the following operating strengths distinguish us from our competition and position us for further growth and enhanced profitability: o Growth in our market. Our primary goal has been to expand our branch network in the St. Louis market while increasing our earnings per share. Since our inception in 1989, we have grown through a combination of internal growth and acquisitions. We have sought to maximize our internal growth opportunities by positioning Allegiant as one of the leading St. Louis community banks. Since the beginning of 2000, we estimate that our deposits and loans, excluding those added through acquisitions, have grown at a compound annual rate of approximately 11.0% and 19.6%, respectively. Since the beginning of 2000, our diluted earnings per share have increased at a compound annual rate of 17.0%. We have supplemented our internal growth with several acquisitions within our market area. Since 2000, we have completed a number of significant acquisitions, including: Equality Bancorp, Inc., a 1 community-based thrift holding company with total assets of approximately $300.4 million, in November 2000; Southside Bancshares Corp., a community-based bank holding company with total assets of approximately $804.9 million, in September 2001; and five branches from Guardian Savings Bank with total deposits of $107.9 million, in December 2001. Additionally, in order to diversify our operations and sources of income, in October 2002, we acquired Investment Counselors, Incorporated, an investment advisory firm with approximately $331.9 million of assets under management. Consistent with our focus on establishing and maintaining a strong presence in the most attractive areas in the St. Louis market, in September 2002, we entered into an agreement to sell Bank of Ste. Genevieve, one of our two subsidiary banks, to First Banks, Inc. Bank of Ste. Genevieve operates two branches located outside of the St. Louis metropolitan area. We expect to complete the sale of Bank of Ste. Genevieve during the first half of 2003. o Strong commercial lending franchise. In order to improve the profitability of our banking operations, over the past several years we have reduced the number of residential mortgages that we hold in our portfolio and have increased the amount of higher yielding commercial loans. Since the beginning of 1998, and in part as a result of opportunities that resulted from the consolidation of the St. Louis banking market, we have hired 23 commercial lending professionals, including a senior credit officer, who average more than 15 years of commercial lending experience in the St. Louis metropolitan area. As these local loan officers have joined our banking team, we have benefited from their existing customer relationships, as well as their local banking expertise. Our target lending customers are small to mid-sized businesses requiring credit ranging in size from $1.0 million to $3.0 million. As a result of our relationship lending focus, we may make larger loans based upon the needs of our business customers and consistent with our loan policy and applicable laws and regulations. During the 12-month period ended September 30, 2002, our commercial business loans grew 17.2%, from $266.2 million to $312.0 million, and our demand deposit accounts grew 16.6%, from $178.0 million to $207.6 million. o Full-service, community banking focus. We focus on serving customers with banking needs that no longer can be adequately served by smaller local institutions but who still desire the personalized service that larger, out-of-state institutions do not effectively provide. Our community banking focus and streamlined management and decision-making procedures allow us to respond quickly to the needs of our individual and business customers and to tailor products and services to meet their needs. We seek to effectively meet the convenience and needs of customers through our extensive branch network that provides our customers at least one branch located within a 20-minute drive from all principal sectors of the St. Louis metropolitan area. Our 37 branches and 59 ATMs throughout the St. Louis metropolitan area also serve to increase recognition of the Allegiant name. In addition, we have sought to further enhance our name recognition by serving as the official bank of the St. Louis Rams football team since July 2000. STRATEGY We believe that our operating strengths and the following strategies position us for further asset and earnings per share growth: o Maintain strong asset quality while growing our commercial loan portfolio. While commercial loan growth is a priority, we remain focused on asset quality. Although our asset quality has been negatively impacted to some degree by our recent acquisitions, our ratio of non-performing assets to total assets improved from 0.93% at December 31, 2001 to 0.67% at September 30, 2002. 2 o Continue to build our relationship-based sales culture. We foster an internal sales culture focused on increasing the number of products that we provide to our customers. Over the past several years, we have significantly improved our internal measures of how many banking products or services we sell to new customers in the first six months of our relationship with those customers. This improvement has resulted from various initiatives, including the recent implementation of an enhanced customer relationship management system to monitor results. o Expand our core deposit base. Expansion of our core deposit base will provide us with a cost-effective and stable source of funding for our loan portfolio. We have improved our non-interest bearing deposits to total deposits ratio from 10.0% at December 31, 2000 to 12.2% at September 30, 2002, which we attribute, to a significant extent, to our efforts to cross-sell deposit services to our commercial customers. We will continue to pursue strategies to increase our non-interest bearing deposits. o Increase our non-interest income. In order to diversify our sources of income and to reduce our dependence on net interest income, we are focused on increasing our non-interest income. Non-interest income as a percentage of our combined net interest income and non-interest income has increased from 17.0% for the year ended 2000 to 23.9% for the nine months ended September 30, 2002. Although our wealth management division has not historically contributed a significant portion of our total revenues, we believe that our acquisition of Investment Counselors, Incorporated, in conjunction with the trust operation we acquired in the Southside transaction, has positioned this division to contribute meaningful revenues to our franchise in the future. These acquired operations enable us to offer a more comprehensive selection of wealth management products and services to our customers. o Maintain strong expense controls. We have implemented a company-wide cost control initiative intended to enhance efficiencies throughout our organization that we refer to as "Project 2004." In addition, we consolidated our banking operations into one primary subsidiary, Allegiant Bank, during 2002. Our increased concentration on cost control efforts is reflected in the improvement of our efficiency ratio from 59.6% for the year ended December 31, 2000 to 54.3% for the nine months ended September 30, 2002. We believe growth of our average branch size and the resulting economies of scale contribute significantly to improving our efficiencies. We have 14 branches that we have owned since December 31, 1999 and which have not been combined with acquired branches. Average deposits at these 14 branches increased from $37.5 million at December 31, 1999 to $55.4 million at September 30, 2002, which we believe reflects the success of our strategy for achieving organic growth. PROJECT 2004 In August 2002, we announced the launch of Project 2004. The mission of Project 2004 is to improve our operating platform by leveraging our acquisition expertise internally. We are approaching this project as if we had acquired our own operations and have evaluated our systems and strategies in order to enhance our delivery of products and services to customers, to improve operating efficiencies and to provide increased revenue. Based on our evaluations, we have undertaken improvement initiatives, several of which have been successfully implemented. We have instituted enhanced budgeting and internal reporting processes and a new customer relationship management system designed to improve the profitability of our customer relationships and identify products and services that allow us to better serve our customers. 3 MANAGEMENT TEAM Our management team is comprised of experienced individuals who average more than 15 years in the banking or financial services industries.

Our efficiency ratio is the quotient of our other non-interest expense over the sum of our net interest income and other non-interest income. 7 RISK FACTORS You should carefully consider the following risk factors before purchasing the shares offered by this prospectus. There could be other factors not listed below that may affect us. OUR ALLOWANCE FOR LOAN LOSSES MAY NOT BE ADEQUATE TO COVER ACTUAL LOAN LOSSES. Our loan customers may not repay their loans according to their terms, and the customers' collateral securing the payment of their loans may be insufficient to assure repayment. Credit losses are inherent in the lending business and could harm our operating results. We make various assumptions and judgments about the collectibility of our loan portfolio and provide an allowance for potential losses based on a number of factors. If our assumptions are wrong, our allowance for loan losses may not be sufficient to cover our loan losses. We may have to increase the allowance in the future. Additions to our allowance for loan losses would decrease our net income. OUR EXPOSURE TO CREDIT RISK IS INCREASED BY OUR COMMERCIAL REAL ESTATE, COMMERCIAL BUSINESS AND CONSTRUCTION LENDING. Commercial real estate, commercial business and construction lending generally involve a higher degree of credit risk than single-family residential lending. These loans involve larger loan balances to a single borrower or groups of related borrowers. These loans are also more susceptible to a risk of loss during a downturn in the business cycle. The underwriting, review and monitoring performed by our officers and directors cannot eliminate all of the risks related to these loans. o OUR COMMERCIAL REAL ESTATE LOANS WILL GENERALLY HAVE HIGHER PRINCIPAL AMOUNTS AND MAY HAVE BALLOON PAYMENTS. Commercial real estate loans involve greater risk because they generally involve higher principal amounts and are dependent, in large part, on sufficient income from the property securing the loan to cover operating expenses and loan payments. In addition, many commercial real estate loans are not fully amortized over the loan period, but have balloon payments due at maturity. A borrower's ability to make a balloon payment typically will depend on being able to either refinance the loan or timely sell the underlying property. Because these loans depend on the successful operation, sale and refinancing of property, they may be affected to a greater extent than residential loans by adverse conditions in real estate markets or the economy. As of September 30, 2002, we had $1.0 billion in commercial real estate loans, including multi-family residential loans. o COMMERCIAL BUSINESS BORROWERS' ABILITY TO REPAY OUR LOANS WILL SUBSTANTIALLY DEPEND UPON THEIR COMMERCIAL SUCCESS AND THE VALUE OF THEIR COLLATERAL MAY BE DIFFICULT TO APPRAISE AND MAY CHANGE OVER TIME. Unlike residential mortgage loans that are based on the borrower's ability to repay the loan from the borrower's income and are secured by real property with a value that is usually readily ascertainable, commercial business loans are typically based on the borrower's ability to repay the loan from the cash flow of the business. These loans involve greater risk because the availability of funds to repay the loan depends substantially on the success of the business itself. In addition, the collateral securing the loans may depreciate over time, be 8 difficult to appraise and fluctuate in value based on the success of the business. As of September 30, 2002, we had $312.0 million in commercial business loans. o OUR CONSTRUCTION LOANS WILL BE BASED UPON ESTIMATES OF CONSTRUCTION COSTS AND PROPERTY VALUES, AND THESE ESTIMATES MAY BE INACCURATE. Risk of loss on a construction loan depends largely upon whether we properly estimate construction costs and a property's value at completion of construction. Construction loans often require disbursement of substantial funds with repayment dependent in part on the success of the ultimate project and the borrower's ability to refinance the indebtedness or sell or lease the property. During the construction phase, a number of factors can result in delays and cost overruns. If the estimate of value is inaccurate, the value of the property securing our loans may be insufficient to ensure full repayment when completed through sale, a permanent loan or seizure of collateral. As of September 30, 2002, we had $245.2 million in construction loans. CHANGES IN THE LOCAL ECONOMIC CONDITIONS COULD ADVERSELY AFFECT OUR LOAN PORTFOLIO. Our success depends to a great extent upon the general economic conditions of the St. Louis metropolitan area. Unlike larger banks that are more geographically diversified, we primarily provide banking and financial services to customers in the St. Louis metropolitan area. Our commercial real estate, commercial business and construction loans, the ability of the borrowers to repay these loans and the value of the collateral securing these loans may be impacted by local economic conditions. Favorable economic conditions may not always exist in our market. WE MAY EXPERIENCE DIFFICULTIES IN MANAGING OUR GROWTH. As part of our overall growth strategy, we have in the past acquired, and may acquire in the future, banks and related businesses that we believe provide a strategic fit with our business. To the extent that we do grow, we may not be able to adequately and profitably manage that growth. We have developed risk management policies and procedures to monitor and manage operational risks in connection with our growth. Our risk management methods may not be effective because, among other reasons, as a result of our recent acquisitions, we may have failed to properly identify our operational risks and because certain of the risks that we will face in the future may be different in nature or magnitude than those we have faced in the past. Operational risks that are not adequately managed by our policies and procedures may result in financial loss, customer dissatisfaction and violations of law. In addition, we may not be able to obtain regulatory approval for potential acquisitions. WE WILL BE SUBJECTED TO SPECIAL RISKS IF WE EFFECT FUTURE ACQUISITIONS. Acquiring other banks and businesses will involve risks commonly associated with acquisitions, including: o potential exposure to unknown or contingent liabilities of any banks or other businesses acquired by us; o difficulty and expense of integrating the operations and personnel of any banks or other businesses acquired by us; 9 o possible increases in leverage resulting from borrowings needed to finance an acquisition or increase regulatory capital; o potential disruption to our business; o potential diversion of our management's time and attention; o potential asset quality issues of any banks or other businesses acquired by us; o impairment of relationships with and the possible loss of key employees and customers of any banks or other businesses acquired by us; and o dilution to our shareholders if we use our common stock as consideration for the acquisition. IT MAY BE DIFFICULT FOR US TO MAINTAIN OUR HISTORICAL GROWTH RATE. We have completed various acquisitions and opened additional branches in the past few years that have significantly enhanced our rate of growth. We may not continue to sustain this rate of growth or grow at all. Competition for suitable acquisition candidates is intense. We may target acquisition candidates that a variety of larger financial institutions with substantially greater resources than us also may be interested in acquiring, which may make it more difficult or expensive for us to acquire potential candidates. THE LOSS OF CERTAIN KEY PERSONNEL COULD ADVERSELY AFFECT OUR OPERATIONS. Our success depends in large part on retaining the services of a limited number of our key management, lending and other banking personnel. We will likely undergo a difficult transition period if we lose the services of any of these individuals. Our success also depends on the experience of the managers of our banking facilities and our lending officers and on their relationships with the communities and the customers they serve. The loss of these key persons could negatively impact the affected banking operations. We may not be able to retain our current key personnel or attract additional qualified key persons as needed. CHANGES IN INTEREST RATES MAY REDUCE OUR NET INTEREST INCOME DUE TO, AMONG OTHER REASONS, THE INTEREST RATE SENSITIVITY OF OUR ASSETS AND LIABILITIES. Like other financial institutions, net interest income will affect our results of operations. Net interest income is the difference between interest earned on loans and investments and interest expense incurred on deposits and other borrowings. Our net interest income will be impacted by changes in market rates of interest, the interest rate sensitivity of our assets and liabilities, prepayments on our loans and investments and limits on increases in the rates of interest charged on our residential real estate loans. Certain of our assets and liabilities may react in different degrees to changes in market interest rates. In addition, interest rates on some types of assets and liabilities may fluctuate prior to changes in broader market interest rates, while rates on other types may lag behind. We continually take measures intended to manage the risks from changes in market interest rates, including using derivatives and other interest-sensitive instruments to manage our interest rate risk. These investments may not perform as we 10 anticipate and may not reduce interest rate exposure in the manner or with the precision we intended. In addition, our position is slightly asset-sensitive and, therefore, in a declining interest rate environment, our net interest income will decrease because our assets will reprice faster than our liabilities. CHANGES IN MARKET RATES OF INTEREST WILL BE BEYOND OUR CONTROL. We will not be able to predict or control changes in market rates of interest. Market rates of interest are affected by regional and local economic conditions, as well as monetary policies of the Board of Governors of the Federal Reserve. The following factors also may affect market interest rates: o inflation or deflation; o slow or stagnant economic growth or recession; o unemployment; o money supply; o international disorders; o instability in domestic and foreign financial markets; and o other factors beyond our control. Market rates of interest will impact the amounts earned on our assets such as loans and securities and the amounts paid on our liabilities such as deposits and borrowings. INSIDERS WILL EFFECTIVELY CONTROL OUR FUTURE OPERATIONS AS A RESULT OF THE CONCENTRATION OF CONTROL OF OUR COMMON STOCK. Currently, our directors and executive officers own approximately 26% of our outstanding common stock. Upon the completion of this offering and the consummation of the proposed sale of Bank of Ste. Genevieve to First Banks, Inc., our directors and officers would own approximately 25% of our outstanding common stock. As a result, these insiders will effectively control the election of our Board of Directors and thus our direction and future operations. Our other shareholders may therefore lack an effective vote with respect to these matters. WE CONTINUALLY ENCOUNTER TECHNOLOGICAL CHANGE, AND WE MAY HAVE FEWER RESOURCES THAN MANY OF OUR COMPETITORS TO CONTINUE TO INVEST IN TECHNOLOGICAL IMPROVEMENTS, WHICH COULD REDUCE OUR ABILITY TO EFFECTIVELY COMPETE. The financial services industry is undergoing rapid technological changes with frequent introduction of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services to enhance customer convenience, as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements. We cannot assure you that we will be able to effectively implement new technology-driven products and services, which could reduce our ability to effectively compete. 11 THE BANKING BUSINESS IS HIGHLY COMPETITIVE. We operate in a competitive environment. In the St. Louis metropolitan area, other commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking firms, investment advisers, financial planners and other financial intermediaries offer similar services. Many of these competitors have substantially greater resources and lending limits and may offer certain services that we do not currently provide. In addition, the extensive regulations that govern us and our banks may not apply to some of our non-bank competitors. Our profitability depends upon the ability of our banks to compete in our market area. WE ARE SUBJECT TO EXTENSIVE AND CONSTANTLY CHANGING REGULATION. The banking industry is heavily regulated under both federal and state law. These regulations are primarily intended to protect depositors and the Federal Deposit Insurance Corporation, not creditors or shareholders. We and our non-bank subsidiaries also are subject to the supervision of the Federal Reserve Board, in addition to other regulatory organizations. Regulations affecting banks and financial services companies undergo continuous change, and the ultimate effect of such changes cannot be predicted. Federal and state governments may modify regulations and laws at any time, and may enact new legislation. In addition to laws and regulations affecting our banking business, compliance with other laws, including the corporate governance standards set forth in the recently enacted Sarbanes-Oxley Act of 2002, regulatory requirements and Nasdaq National Market standards impose administrative costs and burdens on us. TERRORIST ATTACKS AND THREATS, ESCALATION OF MILITARY ACTIVITY IN RESPONSE TO SUCH ATTACKS OR ACTS OF WAR MAY NEGATIVELY AFFECT OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Our business is affected by general economic conditions, fluctuations in consumer confidence and spending, and market liquidity, which can decline as a result of numerous factors outside of our control, such as terrorist attacks and acts of war. The deterioration of the domestic economy could cause an increase in delinquencies in our loan portfolio and loan losses. Future terrorist attacks, like the 2001 attacks in the United States, as well as events occurring in response to, or in connection with, the attacks, including rumors or threats of war, actual conflicts involving the United States or its allies, or military disruptions could materially adversely affect our business, financial condition and results of operations. MANAGEMENT HAS DISCRETIONARY USE OF THE PROCEEDS OF THIS OFFERING. We will contribute substantially all of the net proceeds of this offering to the bank to strengthen its capital position, to support its anticipated loan growth and for other general corporate purposes. The bank will use a portion of the capital contributed to temporarily reduce short-term indebtedness, which may be reborrowed, if necessary, to fund loan growth. We will use the remaining proceeds that are not contributed to the bank for general corporate and working capital purposes. Accordingly, our management will have broad discretion over how to utilize the majority of the net proceeds of this offering. You will be relying on the judgment of our management regarding application of these proceeds. 12 THERE IS A LIMITED TRADING MARKET FOR OUR COMMON STOCK AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT OR ABOVE THE PRICE YOU PAY FOR THEM. The price of our common stock that you purchase in this offering may decrease significantly. Our common stock is quoted on the Nasdaq National Market under the symbol "ALLE." A public trading market having the desired characteristics of liquidity and order depends on the presence in the market of willing buyers and sellers at any given time. While each of the underwriters is currently a market maker in our common stock on the Nasdaq National Market, none of them is obligated to remain a market maker. The presence of willing buyers and sellers depends on the individual decisions of investors and general economic conditions, all of which are beyond our control. FUTURE SALES OF SHARES OF OUR COMMON STOCK IN THE PUBLIC MARKET, OR THE PERCEPTION THAT SUCH SALES MAY OCCUR, MAY DEPRESS OUR STOCK PRICE. If our existing shareholders sell our common stock in the public market following this offering, or if there is a perception that these sales may occur, the market price of our common stock could decline. Following completion of this offering, our directors and executive officers will own approximately 3.7 million shares of common stock (not including shares issuable upon the exercise of options or restricted securities) that are tradable in the public market, subject to limited restrictions imposed by federal securities laws, beginning 180 days after this offering. In addition, our Board of Directors has the authority to issue up to 20% more shares of our authorized but unissued common stock without the vote of our shareholders. Additional issuances of our common stock would dilute the percentage ownership of existing shareholders and may dilute the per share book value of our common stock. ANTI-TAKEOVER PROVISIONS MAY DELAY OR PREVENT AN ACQUISITION BY A THIRD PARTY. Provisions in our Restated Articles of Incorporation and Bylaws and the corporate laws of the State of Missouri may discourage potential acquisition proposals and could delay or prevent a change in control. These provisions include a staggered board, a supermajority voting requirement for certain mergers and asset sales and the right of our Board of Directors to consider the interests of non-shareholder constituencies in connection with acquisition proposals. Furthermore, federal banking laws and regulations require the Federal Reserve Board's approval prior to acquisition of "control" of a bank holding company. These provisions, laws and regulations could delay or prevent a transaction that might otherwise result in a premium over then-current market prices for holders of our shares, and may limit the ability of our shareholders to approve transactions that they may deem to be in their best interests. OUR ABILITY TO PAY DIVIDENDS ON OUR COMMON STOCK IS LIMITED. Our ability to pay dividends on our common stock largely depends on our receipt of dividends from our bank. The amount of dividends that our bank may pay to us is limited by federal and state banking laws and regulations which require the bank to satisfy certain capitalization requirements. Moreover, we may decide to limit the payment of dividends even when we have the legal ability to pay dividends in order to retain earnings for use in our business. In addition, if interest payments required in connection with trust preferred securities issued by two of our subsidiaries are not made or suspended or if we fail to comply with certain covenants under our term loan agreement, we are contractually prohibited from paying dividends on our common stock. 13 CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This prospectus includes forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events. These forward-looking statements are subject to risks, uncertainties and assumptions, including, among other things: o the results of our efforts to implement our business strategy; o adverse changes in the bank's loan portfolio and the resulting credit risk-related losses and expenses; o our ability to manage our growth, including the successful expansion of the customer support, administrative infrastructure and internal management systems necessary to manage that growth; o our ability to attract core deposits; o adverse changes in the economy of our market area that could increase credit-related losses and expenses; o adverse changes in real estate market conditions that could negatively affect credit risk; o the consequences of continued bank acquisitions and mergers in our market area, resulting in fewer but much larger and financially stronger competitors, which could increase competition for financial services to our detriment; o fluctuations in interest rates and market prices, which could negatively affect net interest margins, asset valuations and expense expectations; o changes in regulatory requirements of federal and state agencies applicable to bank holding companies and our present and future bank subsidiaries; o changes in accounting principles; o general economic conditions; o other factors discussed in the "Risk Factors" section of this prospectus; and o other risks and uncertainties detailed from time to time in our filings with the Securities and Exchange Commission. We undertake no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the events discussed in any forward-looking statements in this prospectus might not occur. 14 USE OF PROCEEDS We estimate that the net proceeds to us from the sale of the 1,500,000 shares of our common stock will be approximately $25.2 million ($29.0 million if the underwriters' over-allotment option is exercised in full). Our estimate is based upon an assumed offering price of $18.10 per share (the closing sale price of our common stock on January 29, 2003), after deducting the underwriting discounts and estimated offering expenses of $325,000. We will contribute substantially all of the net proceeds of this offering to the bank to strengthen its capital position, to support its anticipated loan growth and for other general corporate purposes. The bank will use a portion of the contributed capital to temporarily reduce short-term indebtedness, including the borrowings currently outstanding under a credit facility with the Federal Home Loan Bank, which may be reborrowed, if necessary, to fund loan growth. The borrowings to be repaid accrue interest at a weighted average rate of 6.1% per annum and have a weighted average maturity of approximately 10 months. The bank also may use a portion of the net proceeds to open new branches or acquire businesses or branch locations in the future. However, we have no present understandings or agreements or definitive plans relating to any specific acquisitions. We intend to use any remaining proceeds not contributed to the bank for general and working capital purposes. We have not yet determined the amount of net proceeds to be used specifically for each of the foregoing purposes. Accordingly, our management will have significant flexibility in applying the net proceeds from this offering. Pending their use as described above, we may invest the net proceeds from this offering in bank-qualified investments. MARKET FOR COMMON STOCK AND DIVIDENDS Our common stock is listed for quotation on the Nasdaq National Market under the symbol "ALLE." As of January 29, 2003, there were 1,704 shareholders of record of our common stock. Set forth below are the high and low last sale prices for our common stock (as reported by the Nasdaq National Market) for each quarter of 2001, 2002 and 2003 (through January 29, 2003) as well as the amount of cash dividends per share we declared in each quarter.

In 2001, we declared four quarterly cash dividends on our common stock of $0.060 per share, for an aggregate amount of approximately $2.1 million. In 2002, we declared four quarterly cash dividends on our common stock of $0.065 per share, for an aggregate amount of approximately $4.0 million. We have announced an increase in our quarterly dividend to $0.070 per share, to be effective with our first dividend declared in 2003. We generally declare and pay cash dividends quarterly. Because substantially all of the funds available for the payment of cash dividends are derived from the bank, future cash dividends will depend primarily upon the bank's earnings, financial condition and need for funds, as well as government policies and regulations applicable to the bank and us. As of December 31, 2002, the net profits of the bank available for distribution to us as dividends without regulatory approval were approximately $70.6 million. If required payments on outstanding trust preferred securities issued by two of our subsidiaries are not made or suspended or if we fail to comply with certain covenants under our term loan agreement, we will be prohibited from paying dividends on our common stock. 16 CAPITALIZATION The following tables set forth our unaudited consolidated capitalization and regulatory capital ratios (1) at September 30, 2002, (2) on a pro forma basis to reflect the sale of our wholly-owned banking subsidiary, Bank of Ste.

We are authorized to issue 30,000,000 shares of common stock, $0.01 par value per share. As of January 29, 2003, there were 16,202,057 shares of common stock outstanding and 1,176,454 shares reserved for issuance upon exercise of outstanding stock options with a weighted average price of $12.66. DIVIDEND RIGHTS The holders of our common stock are entitled to receive dividends when, as and if declared by our Board of Directors, subject to the rights of holders of then outstanding shares, if any, having preferences with respect to dividends. Under Missouri law, we may not authorize and make distributions if, after giving effect to the distribution, o we would be unable to meet our debts as they become due in the usual course of business; or o our total assets would be less than the sum of (1) our total liabilities plus, (2) the amount that would be needed, if we were to be dissolved at the time of distribution, to satisfy any preferential rights of shareholders upon dissolution superior to the rights of those shareholders receiving the distribution. If we do not make required payments on outstanding trust preferred securities, or are in violation of certain covenants under our term loan agreement, we are prohibited from paying dividends on our common stock. As a bank holding company, our ability to pay distributions will be affected by the ability of our bank to pay dividends. Our ability, as well as the ability of the bank, to pay dividends in the future currently is, and could be further, influenced by bank regulatory requirements and capital guidelines. VOTING RIGHTS Except as described below regarding the election of directors, each holder of common stock is entitled to one vote per share. The quorum for shareholders' meetings is a majority of the outstanding shares entitled to vote represented in person or by proxy. PROVISIONS REGARDING CERTAIN BUSINESS COMBINATIONS Our Restated Articles of Incorporation require the affirmative vote of the holders of at least 80% of the outstanding shares of our capital stock to approve a merger and certain other business combinations involving any holder of 5% or more of our common stock and us. However, if 75% or more of the members of our Board of Directors approve the transaction, the supermajority shareholder vote is not required. As of January 29, 2003, our directors and executive officers own approximately 26% of our outstanding common stock. Upon the completion of this offering and the consummation of the proposed sale of Bank of Ste. Genevieve to First Banks, Inc., our directors and officers would own approximately 25% of our outstanding common stock. As a result, these insiders will effectively control the election of our Board of Directors and thus our direction and future operations, and our other shareholders may lack an effective vote with respect to these matters. Consequently, the directors and executive officers possess 23 sufficient voting power to significantly affect the vote on, and perhaps prevent, certain mergers and other business combinations. ELECTION, CLASSIFICATION AND REMOVAL OF DIRECTORS Our Restated Articles of Incorporation provide for a classified Board of Directors, with approximately one-third of the entire Board of Directors being elected each year and with directors serving for terms of three years. Directors are elected by a plurality of votes cast. Holders of common stock have the right to cumulate their votes in the election of directors. Our Restated Articles of Incorporation provide that any director, or the entire Board of Directors, may be removed at any time by our shareholders, without cause, by the affirmative vote of the holders of at least 80% of the shares entitled to vote for the election of directors, and may be removed for cause by an affirmative vote of a majority of the shares entitled to vote. SHAREHOLDER APPROVAL OF TRANSACTIONS An affirmative vote of at least 80% of the shares of our common stock is required to amend the provisions of our Restated Articles of Incorporation relating to the removal of a director or the approval requirement for a merger or business combination with a holder of 5% or more of our common stock. In addition, under Missouri law an affirmative vote of at least two-thirds of the shares of our common stock is required to approve a merger or sale of substantially all of our assets. Except for the foregoing, any other proposal voted on by the shareholders will be approved if the majority of the votes cast at the shareholders' meeting (at which a quorum is present) called for the purpose of considering any such action are cast in favor of the proposal. LIQUIDATION RIGHTS In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to receive equally and pro-rata per share any assets distributable to shareholders, after payment of debts and liabilities. OTHER MATTERS Holders of our common stock do not have preemptive rights or conversion rights with respect to our common stock. Except in connection with certain business combinations and except as noted below, we can issue new shares of authorized but unissued common stock without shareholder approval. The bylaws of The Nasdaq Stock Market, Inc. governing the Nasdaq National Market, on which our common stock is quoted, require issuers to obtain shareholder approval for the issuance of securities in connection with the acquisition of a business, company, assets, property or securities representing such interests where the present or potential issuance of common stock or securities convertible into common stock in connection with such acquisition could result in an increase of 20% or more in the outstanding shares of common stock. Accordingly, the future issuance of common stock may require shareholder approval under those rules. CERTAIN STATUTORY PROVISIONS We are subject to the business combination provisions under Missouri law, which allow our Board of Directors to retain discretion over the approval of certain business combinations. We are also subject to the control shares acquisition provision under Missouri law, which places restrictions on the voting rights of an acquiror with respect to any shares of voting stock which increase its equity ownership to more than specified thresholds unless certain conditions are satisfied. Missouri law also 24 permits our Board of Directors to consider the interests of non-shareholder constituencies in connection with acquisition proposals. These provisions may make it more difficult for there to be a change in control of us or for us to enter into certain business combinations than if we were not subject to these provisions. TRANSFER AGENT UMB Bank, n.a., Kansas, City, Missouri serves as the transfer agent of our issued and outstanding common stock. 25 UNDERWRITING Subject to the terms and conditions of an underwriting agreement, the underwriters named below, for whom Legg Mason Wood Walker, Incorporated is acting as representative, have severally agreed to purchase from us, and we have agreed to sell to them, an aggregate of 1,500,000 shares of common stock in the amounts set forth opposite each underwriter's name below: NUMBER OF UNDERWRITERS SHARES ------------ -------------- Legg Mason Wood Walker, Incorporated...................... RBC Dain Rauscher Inc..................................... Stifel, Nicolaus & Company, Incorporated.................. Howe Barnes Investments, Inc.............................. -------------- Total............................................ 1,500,000 ============== The underwriting agreement provides that the obligations of the underwriters are subject to various conditions contained in the underwriting agreement. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or, in certain cases, that the underwriting agreement may be terminated. The nature of the underwriters' obligation is such that they are committed to purchase and pay for all of the shares of common stock (other than those covered by the over-allotment option discussed below) if any are purchased. We have granted the underwriters an option to purchase up to 225,000 additional shares of common stock at the same price per share to be paid by the underwriters for the other shares of common stock being offered. This option is exercisable from time to time for 30 days after the date of this prospectus, but may be exercised by the underwriters only to cover any over-allotments. If the underwriters elect to purchase any of the shares of common stock under this option, each underwriter will be committed to purchase the additional shares of common stock in approximately the same proportion allocated to them in the table above. At our request, the underwriters have reserved up to 100,000 shares of our common stock offered by this prospectus for sale to our directors and officers at the public offering price set forth on the cover page of this prospectus. These persons must commit to purchase no later than the close of business on the day following the date of this prospectus. The number of shares available for sale to the general public will be reduced to the extent these persons purchase the reserved shares. We are not making loans to these executive officers or directors to purchase such shares. We have agreed that, without the prior consent of the underwriters, we will not directly or indirectly offer, sell or otherwise dispose of any shares of common stock or any securities which may be converted into or exchanged for common stock for a period of 180 days after the effective date of the registration statement of which this prospectus is a part, subject to certain exceptions. All of our executive officers and directors have agreed that, without the prior written consent of the underwriters, they will not directly or indirectly offer, sell or otherwise dispose of any shares of common stock or any securities which may be converted into or exchanged for common stock for a period ending 180 days after the effective date of the registration statement of which this prospectus is a part, subject to certain exceptions. The following table shows the public offering price, underwriting discount and proceeds to us before expenses. Certain expenses of the underwriters that are reimbursable by us are not included in the 26 table. The information assumes either no exercise or full exercise by the underwriters of their over-allotment option. PER SHARE WITHOUT OPTION WITH OPTION --------- -------------- ----------- Public offering price.......................... $ $ $ Underwriting discount.......................... Proceeds, before expenses...................... The underwriters will initially offer the shares of common stock to the public at the price stated on the cover page. The underwriters may offer shares of common stock to selected dealers at the public offering price less a concession of up to $ per share. Those dealers may reallow a discount not in excess of $ per share to other brokers and dealers. After the initial offering of the shares, the underwriters may change the offering price, concession, discount and other selling terms. We estimate that we will spend approximately $325,000 for printing, depository fees, legal and accounting fees and other expenses of the offering in addition to the underwriting compensation. In connection with the offering, the underwriters and their affiliates may engage in transactions, effected in accordance with the Securities and Exchange Commission's Regulation M, that are intended to stabilize, maintain or otherwise affect the market price of the common stock. These transactions may include over-allotment or other mechanisms through which the underwriters create a selling syndicate short position by selling more shares of common stock than the underwriters are committed to purchase. The underwriters may elect to cover any short position by purchasing common stock in the open market or by exercising the over-allotment option. The underwriters also may bid for, and purchase, the common stock, including at a price above that which might otherwise prevail in the open market for the purpose of preventing or retarding a decline in the market price of the common stock. The underwriters may impose penalty bids under which selling concessions allowed to syndicate members or other dealers participating in the offering are reclaimed if shares of common stock previously distributed in the offering are repurchased by the underwriters. Any of these transactions may maintain or stabilize the price for the common stock at a level above that which might otherwise prevail in the open market. None of the underwriters or we make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the market price of the common stock. The underwriters are not required to engage in any of these transactions and may discontinue them at any time without notice if they commence them. The underwriters may effect these transactions on the Nasdaq National Market or elsewhere. The underwriters and selling group members may also engage in passive market making transactions in the common stock in accordance with Rule 103 of Regulation M. In general, a passive market maker may not bid for or purchase shares of common stock at a price that exceeds the highest independent bid. In addition, the net daily purchases made by any passive market maker generally may not exceed 30% of its average daily trading volume in the common stock or 200 shares, whichever is greater. A passive market maker's bid size may not exceed the minimum quotation size for the common stock or the market maker's remaining purchase capacity, whichever is less. A passive market maker must identify passive market making bids as such on the Nasdaq electronic inter-dealer reporting system. Passive market making may stabilize or maintain the market price of the common stock above independent market levels. Underwriters and dealers are not required to engage in passive market making and may end passive market making activities at any time. 27 We have agreed to indemnify the underwriters against liabilities arising from the offering of the shares of common stock, including civil liabilities under the Securities Act of 1933, or to contribute to payments that the underwriters may be required to make in connection with those liabilities. Legg Mason assisted us in evaluating and rendered an opinion to our Board of Directors as to the fairness, from a financial point of view, to us of the approximately 974,150 shares of our common stock to be received by us in connection with our proposed disposition of the shares of Bank of Ste. Genevieve to First Banks, Inc. We have compensated Legg Mason for advising us and rendering this opinion. Under the rules of the NASD, Legg Mason's compensation for such services may be considered by the NASD to be compensation for the sale of common stock offered in this prospectus even though such compensation is not intended for or contingent upon the sale of the common stock. In addition, certain of the underwriters and their affiliates have provided in the past and may provide in the future investment banking services for us or our affiliates for which they would expect to receive customary fees and commissions. The underwriters are currently market makers in our common stock on the Nasdaq National Market. LEGAL MATTERS Our attorneys, Thompson Coburn LLP, St. Louis, Missouri, will opine as to the validity of the common stock offered by us, as well as certain other legal matters related to the sale of the shares. Certain legal matters relating to the offering will be passed upon for the underwriters by Barack Ferrazzano Kirschbaum Perlman & Nagelberg LLC, Chicago, Illinois.

INDEMNIFICATION OF DIRECTORS AND OFFICERS Sections 351.355(1) and (2) of The General and Business Corporation Law of the State of Missouri provide that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of an action or suit by or in the right of the corporation, the corporation may not indemnify such persons against judgments and fines and no person shall be indemnified as to any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation, unless and only to the extent that the court in which the action or suit was brought determines upon application that such person is fairly and reasonably entitled to indemnity for proper expenses. Section 351.355(3) provides that, to the extent that a director, officer, employee or agent of the corporation has been successful in the defense of any such action, suit or proceeding or any claim, issue or matter therein, he shall be indemnified against expenses, including attorneys' fees, actually and reasonably incurred in connection with such action, suit or proceeding. Section 351.355(7) provides that a corporation may provide additional indemnification to any person indemnifiable under subsection (1) or (2), provided such additional indemnification is authorized by the corporation's articles of incorporation or an amendment thereto or by a shareholder-approved bylaw or agreement, and provided further that no person shall thereby be indemnified against conduct which was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct. II-1 Article XII of our Bylaws provides that we extend to our directors and officers the indemnification specified in Sections 351.355(1) and (2) and the additional indemnification authorized in Section 351.355(7) of The General and Business Corporation Law. Pursuant to directors' and officers' liability insurance policies, with total annual limits of $2.0 million, our directors and officers are insured, subject to the limits, retention, exceptions and other terms and conditions of the policies, against liability for any actual or alleged error, misstatement, misleading statement, act or omission, or neglect or breach of duty by our directors or officers, individually or collectively, or any matter claimed against them solely by reason of their being our directors or officers.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a II-2 court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the County of St. Louis and State of Missouri on the 30th day of January, 2003.
