PROXY STATEMENT OF CITIZENS FIRST FINANCIAL CORP.


PROSPECTUS OF MAIN STREET TRUST, INC.

Merger Proposed—Your Vote is Very Important

        The boards of directors of Main Street Trust, Inc. and Citizens First Financial Corp. have approved a merger agreement that would result in Main Street's acquisition of Citizens.

        In the transaction, subject to the limitations described in this document, stockholders of Citizens will have the election to receive shares of common stock of Main Street, cash or a combination of both in exchange for their shares of Citizens stock.

        Citizens stockholders will be entitled to receive either $35.00 in cash or 1.1051 shares of Main Street common stock for each share of Citizens common stock they own. Because the exchange ratio of 1.1051 shares of Main Street common stock is fixed, the total value of the merger consideration that Citizens stockholders will receive in the merger will fluctuate as the price of Main Street common stock changes. We encourage Citizens' stockholders to obtain current market price quotations for Main Street common stock.

        Main Street common stock is traded on the over-the-counter bulletin board under the symbol "MSTI.OB." The closing price of Main Street common stock on [                        ], 2005, was $ [            ]. Citizens common stock is traded on the Nasdaq National Market System under the symbol "CFSB." The closing price of Citizens common stock on [                        ], 2005, was $ [            ].

        To complete this merger, Main Street must obtain regulatory approvals and Citizens must obtain the approval of its stockholders. Citizens will hold a special meeting to vote on the merger agreement and the transactions it contemplates. Your vote is very important. Whether or not you plan to attend the special meeting, please take the time to vote by completing and mailing the enclosed proxy card.

        For a description of the significant considerations in connection with the merger and related matters described in this document, see "Risk Factors" beginning on page 21.

        We encourage you to read this entire document carefully. This proxy statement-prospectus gives you detailed information about the merger, and it includes a copy of the merger agreement as Appendix A.

  Sincerely,

 

C. William Landefeld
President and Chief Executive Officer of

QUESTIONS AND ANSWERS ABOUT ELECTING THE FORM OF MERGER CONSIDERATION

Q:    What will I receive in the merger?

A:    You will be entitled to receive either $35.00 in cash or 1.1051 shares of Main Street common stock for each share of Citizens common stock that you own at the effective time of the merger.

If you own fewer than 100 shares of Citizens common stock, you will automatically receive cash for all of your shares. If you own 100 or more shares of Citizens common stock, you will be able to elect the form of consideration you would like in the merger, subject to the limitations described in this document. You have the option to choose Main Street common stock, cash, or a combination of both. If you elect to receive Main Street common stock, you will receive 1.1051 shares of Main Street for each of your shares of Citizens common stock. If you elect to receive cash, you will receive $35.00 for each of your shares of Citizens common stock. You may also elect to receive a combination of Main Street common stock and cash, except that you may not elect to receive stock in exchange for fewer than 100 shares of your Citizens common stock.

All stockholder elections are subject to the requirement that 50% of all Citizens shares must be converted into the right to receive Main Street common stock and 50% of all Citizens shares must be converted into the right to receive cash. The merger agreement gives Main Street the right to modify your election to satisfy this 50% stock and 50% cash requirement. Therefore, depending on elections made by other stockholders, you may ultimately receive more or fewer shares of Main Street common stock or more or less cash than you otherwise elected to receive.

If you fail to make a timely election, you will be allocated cash and/or shares as needed to satisfy the overall 50% stock and 50% cash requirement discussed above.

Because the exchange ratio of 1.1051 shares of Main Street common stock per share of Citizens common stock is fixed, the value of the stock consideration will fluctuate as the price of Main Street common stock changes. You should obtain current market price quotations for Main Street common stock to determine the current value of the stock consideration.

Q:    How do I elect the form of payment I will receive in the merger?

A:    Shortly after the merger, you will receive a form in the mail with written instructions on how to elect the form of payment you want receive in the merger.

Because a fixed amount of 50% of the outstanding shares of Citizens common stock must be converted into cash, including any appraisal shares, stockholders may receive, through a proration procedure described in this document, less cash and more shares of Main Street common stock than they originally anticipated. Similarly, because a fixed amount of 50% of the Citizens common stock must be converted into Main Street common stock, stockholders may receive fewer shares and more cash than they originally anticipated.

Completed election forms must be returned to Main Street Bank & Trust, which is serving as the exchange agent in this transaction, on or before 5:00 p.m., Champaign, Illinois time, on [                        ], 2005.

Q:    How do I exchange my Citizens stock certificates?

A:    With the election form, a letter of transmittal, which will include instructions on where to surrender your stock certificates for exchange, will be mailed to you. The exchange agent will allocate cash and Main Street common stock among Citizens' stockholders in accordance with the terms of the merger agreement and will transmit the merger consideration to the former Citizens stockholders.

Q:    Whom should I call with questions?

A:    You should contact:

    Citizens First Financial Corp.
2101 North Veterans Parkway
Bloomington, Illinois 61704
    Attention:   Dallas G. Smiley,
Executive Vice President,
Secretary and Treasurer
    Telephone:   (309) 661-8700

SUMMARY

        This brief summary highlights selected information from this proxy statement-prospectus and does not contain all of the information that is important to you. We urge you to carefully read this entire document and the other documents we refer to in this document. These will give you a more complete description of the transaction we are proposing. For more information about Main Street and Citizens, see "Where You Can Find More Information." We have included page references in this summary to direct you to other places in this proxy statement-prospectus where you can find a more complete description of the topics we have summarized.

General

This proxy statement-prospectus relates to the proposed acquisition of Citizens by Main Street. Main Street and Citizens believe that the acquisition will enhance stockholder value by allowing Citizens stockholders to receive Main Street common stock and cash in exchange for their shares of Citizens common stock and by permitting Main Street to expand its presence with the addition of new markets in Illinois.

The Companies
(pages            and            )

Main Street Trust, Inc.
100 W. University Avenue
Champaign, Illinois 61824
(217) 351-6500

Main Street, an Illinois corporation, is a financial services company with a subsidiary bank, Main Street Bank & Trust, located in central Illinois. At September 30, 2004, Main Street reported, on a consolidated basis, total assets of $1.24 billion, deposits of $990.0 million, stockholders' equity of $112.93 million and trust assets under administration of approximately $1.65 billion.

Citizens Acquisition LLC is a Delaware limited liability company and a wholly-owned subsidiary of Main Street. Citizens Acquisition LLC was formed solely for the purpose of completing the merger, and has not had any operations to date other than those incidental to the merger agreement.

Citizens First Financial Corp.
2102 North Veterans Parkway
Bloomington, Illinois 61704
(309) 661-8700

Citizens, a Delaware corporation, is a thrift holding company. Through Citizens Savings Bank, an Illinois state savings bank, Citizens conducts a range of commercial and personal banking activities from five locations throughout central Illinois. At September 30, 2004, Citizens reported, on a consolidated basis, total assets of $327.1 million, deposits of $231.4 million and stockholders' equity of $34.2 million.

Special Meeting
(pages            and            )

A special meeting of Citizens stockholders will be held on [                        ], 2005, at [    ]:00 [    ].m., local time, at [                        ]. At the special meeting, stockholders will be asked:

Record Date; Vote Required
(pages            and            )

You may vote at the meeting of Citizens' stockholders if you owned Citizens common stock at the close of business on [                        ], 2005. You can cast one vote for each share of Citizens common stock that you owned at that time. To adopt the merger agreement and approve the transactions it contemplates, the holders of a majority of the outstanding voting shares of Citizens as of the record date must vote in favor of doing so.

You may vote your shares in person by attending the meeting or by mailing us your proxy if you are unable to or do not wish to attend. You can revoke your proxy at any time before Citizens takes a vote at the meeting by submitting a written notice revoking the proxy or a later-dated proxy to the secretary of Citizens, or by attending the meeting and voting in person.

4



Authority to Adjourn Special Meeting to Solicit Additional Proxies
(page            )

Citizens is asking its stockholders to grant full authority for the special meeting to be adjourned, if necessary, to permit solicitation of additional proxies to approve the transactions proposed by this proxy statement-prospectus.

Appraisal Rights
(page            )

As more fully described beginning on page    , under Delaware law, Citizens stockholders have the right to demand appraisal of his or her shares and receive the fair value of their shares of Citizens common stock in cash.

To demand appraisal and receive the fair value of their shares, Citizens stockholders must follow the procedures outlined in Appendix C.

If you demand appraisal of your shares and the conditions outlined in Appendix C are met, your shares of Citizens common stock will not be converted into the right to receive the consideration provided in the merger agreement. Instead, your only right will be to receive the fair value in cash of your Citizens shares as determined by mutual agreement between you and Main Street or by appraisal of a court if you are unable to agree. You should be aware that submitting a signed proxy card without indicating a vote with respect to the merger will be deemed a vote "FOR" the merger and a waiver of your appraisal rights. A vote "AGAINST" the merger does not dispense with the other requirements for exercising appraisal rights under Delaware law.

The fair value may be more or less than the consideration you would have received under the terms of the merger agreement. If you demand appraisal of your shares and you complete the process of having a court determine the fair value of your shares in accordance with Delaware law, the amount you are awarded could be less than the value of the cash and shares of Main Street common stock that you would have received in the merger.

Recommendation to Stockholders
(page            )

Citizens' board of directors believes that the merger agreement and the merger are fair to you and in your best interests, and unanimously recommends that you vote "FOR" the proposal to adopt the merger agreement and approve the transactions it contemplates.

Share Ownership of Citizens' Directors
(pages            and            )

On the record date, Citizens' directors owned 232,250 shares, or approximately 14.82% of the outstanding shares of Citizens common stock. Citizens' directors have agreed to vote their shares to approve the merger agreement and the transactions it contemplates. However, because they own only approximately 14.82% of the outstanding shares of Citizens common stock, there is no assurance that the proposal will be approved.

The Merger
(page            )

We have attached a copy of the merger agreement to this document as Appendix A. Please read the merger agreement. It is the legal document that governs the merger.

We propose a combination in which Citizens will merge with and into a wholly-owned subsidiary of Main Street. The surviving entity will immediately liquidate, leaving Main Street as the direct owner of Citizens Savings Bank. We expect to complete the merger in the second quarter of 2005, although delays could occur.

What You Will Receive in the Merger
(page            )

Citizens stockholders will have the right to receive, for each share of Citizens common stock that they own as of the effective time of the merger, either 1.1051 shares of Main Street common stock or $35.00 in cash.

Subject to the limits described below, you are able to elect the form of consideration that you would like to receive as a result of the merger. You have the option to choose Main Street common stock, cash, or a combination of both. However, if you hold less than 100 shares of

5



Citizens common stock, you cannot make an election and will automatically receive only cash. In addition, if you elect to receive a combination of stock and cash, you may not elect to receive stock in exchange for fewer than 100 shares of your Citizens common stock.

All stockholder elections are subject to the requirement that 50% of all Citizens shares must be converted into the right to receive Main Street common stock and 50% of the Citizens shares must be converted into the right to receive cash. The merger agreement gives Main Street the right to modify your election to satisfy this 50% stock and 50% cash requirement. Therefore, depending on elections made by other stockholders, you may ultimately receive more or fewer shares of Main Street or more or less cash than you otherwise elected to receive.

If you fail to make a timely election, you will be allocated cash and/or shares as needed to satisfy the overall 50% stock and 50% cash requirements discussed above.

Because the exchange ratio of 1.1051 shares of Main Street common stock is fixed, the value of the stock portion of the merger consideration will fluctuate as the price of Main Street common stock changes. You should obtain current market price quotations for Main Street common stock to determine the current value of the stock portion of the merger consideration.

Exchange of Stock Certificates
(page            )

On or shortly after the effective date of the merger, Citizens stockholders who own 100 or more shares will receive a letter and instructions on how to make an election and how to surrender their stock certificates representing Citizens common stock in exchange for cash and/or Main Street stock certificates. Citizens stockholders who own less than 100 shares will receive a letter and instructions on how to surrender their stock certificates for cash. You must carefully review and complete these materials and return them as instructed along with your Citizens Common stock certificates. Please do not send any stock certificates to Main Street or Citizens until you receive these instructions.

Ownership After the Merger
(page            )

Assuming that the maximum 1,761,311 shares of Citizens common stock are exchanged in the merger, Main Street will issue 973,212 shares of its common stock and $30,822,942.50 in cash to Citizens stockholders in the merger. Based on the number of outstanding shares of Main Street common stock at [            ], 2005, this would constitute approximately [    ]% of the outstanding common stock of Main Street immediately following the merger.

Effective Time of the Merger
(page            )

The merger will become final when a certificate of merger is filed with the Secretary of State of the State of Delaware. If Citizens' stockholders approve the merger at their special meeting, and if Main Street obtains all required regulatory approvals, we anticipate that the merger will be completed in the second quarter of 2005, although delays could occur.

We cannot assure you that we can obtain the necessary stockholder and regulatory approvals or that the other conditions to completion of the merger can or will be satisfied.

Federal Income Tax Consequences
(page            )

The merger will be tax-free for federal income tax purposes to Citizens stockholders who receive solely Main Street shares in the merger. For Citizens stockholders who receive cash in exchange for any of their Citizens shares or for those stockholders who receive cash for fractional shares, the cash received will either be characterized as a dividend (to the extent of Citizens' earnings and profits) for U.S. federal income tax purposes or it will be characterized as a payment in exchange for stock. Because the determination of each stockholder's tax treatment is highly dependent upon that stockholder's specific facts and relationships with other stockholders, it is not possible to reach any general conclusions with respect to this issue.

Reasons for the Merger
(pages            and            )

Main Street.    The Main Street board of directors believes that the merger will enhance stockholder value by increasing the capability to offer a full range of financial products and services in many of central Illinois' most attractive markets.

Citizens.    The Citizens board of directors believes that the merger with Main Street is consistent with Citizens' goal of enhancing stockholder value. In addition, the Citizens board of directors believes that the customers and communities served by Citizens will benefit from the merger.

You can find a more detailed discussion of the background of the merger and Main Street's and Citizens' reasons for the merger in this document under "Description of Transaction—Background of the Merger" beginning on page     , "—Main Street's Reasons for the Merger" beginning on page     and "—Citizens' Reasons for the Merger and Board Recommendation" beginning on page     .

The discussion of our reasons for the merger includes forward-looking statements about possible or assumed future results of our operations and the performance of the combined company after the merger. For a discussion of factors that could affect these future results, see "A Warning About Forward-Looking Statements" on page            .

Opinion of Financial Advisor
(page            )

In deciding to approve the merger, Citizens' board of directors considered the opinion of Sandler O'Neill & Partners, L.P. dated November 7, 2004, that (subject to the assumptions and limitations on review set forth in the opinion) the merger consideration to be received by Citizens' stockholders is fair, from a financial point of view to those stockholders. The full text of this opinion is attached to this document as Appendix B. You are encouraged to read this opinion carefully and in its entirety.

Sandler O'Neill acted as financial advisor to Citizens in connection with the merger and will receive a fee of approximately $[    ] (based upon the closing price of Main Street's common stock on [            ] , 2005) in connection therewith, a substantial portion of which is contingent and payable upon closing of the merger. Sandler O'Neill has also received a fee of $100,000 in connection with rendering its opinion. This fee will be credited against that portion of the transaction fee payable upon closing of the merger.

Conditions to Completion of the Merger
(page            )

The completion of the merger depends on a number of conditions being met. Subject to exceptions described in the merger agreement, these include:

7


A party to the merger agreement could choose to complete the merger even though a condition to its obligation has not been satisfied, as long as the law allows it to do so. We cannot be certain when or if the conditions to the merger will be satisfied or waived, or that the merger will be completed.

Termination and Termination Fees
(page            )

The parties can mutually agree at any time to terminate the merger agreement without completing the merger. Also, either party can decide, without the consent of the other, to terminate the merger agreement if the merger has not been completed by September 7, 2005, unless the failure to complete the merger by that time is due to a violation of the merger agreement by the party that wants to terminate the merger agreement.

In addition, either Main Street or Citizens can terminate the merger agreement if the conditions to its respective obligation to complete the merger have not been satisfied. Main Street may terminate the agreement if environmental investigations indicate the presence of material adverse environmental conditions that cannot be removed or remediated at a cost of $250,000 or less. Citizens is also permitted to terminate the agreement if the average trading price of Main Street falls below $26.92 and if Main Street's stock does not perform as well as that of selected bank holding companies, provided that Main Street does not elect to adjust the consideration in such a way that the per share value of the merger consideration is equal to at least $29.75.

Either Main Street or Citizens may be required to pay the other party a termination fee if the merger agreement is terminated due to certain circumstances outlined in the merger agreement. For a discussion of these conditions and fees, see "Description of the Transaction—Termination and Termination Fees."

Waiver and Amendment
(page            )

Main Street and Citizens may jointly amend the merger agreement and either party may waive its right to require the other party to adhere to any term or condition of the merger agreement. However, neither may do so after Citizens' stockholders approve the merger, if the amendment or waiver would materially and adversely affect the rights of Citizens' stockholders.

Regulatory Approvals
(page            )

We cannot complete the merger unless it is approved by the Federal Reserve Board and the Illinois Department of Financial and Professional Regulation. Once the Federal Reserve Board approves the merger, we have to wait anywhere from 15 to 30 days before we can complete the merger, during which time the U.S. Department of Justice can challenge the merger on antitrust grounds.

Main Street has filed all of the required applications or notices with the Federal Reserve Board and the Illinois Department of Financial and Professional Regulation.

Management and Operations After the Merger
(page            )

Following the merger, Citizens Acquisition LLC, the surviving entity in its merger with Citizens, will dissolve, leaving Main Street as the direct holding company of Citizens Savings Bank. The directors and officers of Main Street will remain the same as they were prior to the merger.

Interests of Certain Persons in the Merger
(page            )

Some of Citizens' directors and officers have interests in the merger that differ from, or are in addition to, their interests as stockholders in Citizens, as described beginning on page     .

The members of Citizens' board of directors knew about these additional interests and considered them when they approved the merger agreement and the transactions it contemplates.

Accounting Treatment
(page            )

The merger will be accounted for as a "purchase transaction" in accordance with accounting principles generally accepted in the United States.

8



Expenses
(page            )

Each of Main Street and Citizens will pay its own expenses in connection with the merger, including filing, registration and application fees, printing fees and fees and expenses of its own financial or other consultants, accountants and counsel.

Material Differences in the Rights of Stockholders
(page            )

Upon completion of the merger, Citizens stockholders, other than those solely receiving cash in the merger, will become stockholders of Main Street and their rights will be governed by Illinois law and by Main Street's articles of incorporation and bylaws. There are material differences between the rights of the stockholders of Main Street and Citizens, which we describe in this document.

Comparative Per Share Data

        The following table presents comparative historical per share data of Main Street and Citizens and unaudited pro forma per share data that reflect the combination of Main Street using the purchase method of accounting.

        The information listed as "equivalent pro forma" for Citizens was obtained by multiplying the pro forma amounts for Main Street by the exchange ratio of 1.1051.

        We expect that we will incur merger and integration charges as a result of combining our companies. We also anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses and the opportunity to earn more revenue. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect these expenses or benefits and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have actually been had our companies been combined as of the dates or for the periods presented.

Market Price Information

        Main Street common stock is traded on the over-the-counter bulletin board under the symbol "MSTI.OB." Citizens common stock is traded on the Nasdaq National Market System under the symbol "CFSB." On November 5, 2004, the business day immediately preceding the public announcement of the execution of the merger agreement, and [            ], 2005, the most recent practicable date prior to the mailing of this document, the market prices of Main Street common stock and Citizens common stock, and the equivalent price per share of Main Street common stock giving effect to the merger, were as follows:

 
  Closing Sales Price
 
 
  Main Street
  Citizens
  Equivalent Price
Per Share of
Main Street
Common Stock

 
Price per share                    
November 5, 2004   $ 31.00   $ 29.50   $ 34.26  
[                        ], 2005   $ [           ] $ [           ] $ [           ]

        The "Equivalent Price Per Share of Main Street Common Stock" at each specified date in the above table represents the product achieved when the closing sales price of a share of Main Street common stock on that date is multiplied by the exchange ratio of 1.1051.

        The market price of Main Street common stock will likely fluctuate between the date of this document and the date on which the merger is completed and after the merger. Because the exchange ratio of 1.1051 is fixed, the value of the stock portion of the merger consideration will fluctuate as the price of Main Street common stock changes. In addition, the value of the shares of Main Street common stock that Citizens stockholders will receive in the merger may increase or decrease after the merger.

        By voting to adopt the merger agreement and approve the transactions it contemplates, Citizens stockholders will be choosing to invest in Main Street to the extent they receive Main Street common stock in exchange for any portion of their shares of Citizens common stock. An investment in Main Street's common stock involves significant risk. In addition to the other information included in this proxy statement-prospectus, including the matters addressed in "A Warning About Forwarding-Looking Statements" beginning on page    , Citizens stockholders should carefully consider the matters described below in "Risk Factors" beginning on page    when determining whether to adopt the merger agreement and approve the transactions it contemplates.

Unaudited Pro Forma Financial Data

        The following unaudited pro forma financial information and related footnotes are presented to show the impact of the merger on the historical financial position and results of operations of Main Street. As a result of the merger, each share of Citizens common stock will be converted into the right to receive either $35.00 in cash or 1.1051 shares of Main Street common stock.

        The unaudited pro forma consolidated balance sheet reflects the historical position of Main Street and Citizens at December 31, 2003, and September 30, 2004, with pro forma adjustments based on the assumption that the merger was consummated on those dates. The pro forma adjustments are based on the purchase method of accounting. The unaudited pro forma consolidated income statement assumes that the merger was completed on the first day of the earliest indicated period, i.e., January 1, 2003 (for the period ended December 31, 2003), or January 1, 2004 (for the period ended September 30, 2004).

        The unaudited pro forma earnings amounts do not reflect any potential earnings enhancements or cost reductions that are expected to result from the consolidation of Main Street's and Citizens' operations and are not necessarily indicative of the results expected of the future combined operations. We cannot give any assurances with respect to the ultimate level of earnings enhancements or cost reductions to be realized.

        The following information should be read in conjunction with, and is qualified in its entirety by, the consolidated financial statements and accompanying notes of Main Street and Citizens included with or incorporated by reference in this proxy statement-prospectus. Results of Main Street and Citizens, as applicable, for the interim period ended September 30, 2004, and for the year ended December 31, 2003, are not necessarily indicative of results of operations or the combined financial position that would have resulted had the merger actually been completed at the beginning of the period indicated.

Selected Historical Financial Data

        The following tables present selected consolidated unaudited financial data as of September 30, 2003, and 2004, and for the nine-month periods then ended, and selected consolidated audited financial data as of December 31, 1999, 2000, 2001, 2002, and 2003, for each of the five years then ended, for each of Main Street and Citizens. The information for Main Street is based on the historical financial information that is contained in reports Main Street has previously filed with the Securities and Exchange Commission, which can be found in its Form 10-Q for the quarter ended September 30, 2004, and its Annual Report on Form 10-K for the year ended December 31, 2003. The information for Citizens is based on the historical financial information that is contained in reports Citizens has previously filed with the Securities and Exchange Commission, which can be found in its Form 10-Q for the quarter ended September 30, 2004, and its Annual Report on Form 10-K for the year ended December 31, 2003. These documents are incorporated by reference in this proxy statement-prospectus. See "Where You Can Find More Information" on page    .

        You should read the following tables in conjunction with the consolidated financial statements described above.

        Historical results do not necessarily indicate the results that you can expect for any future period. We believe that we have included all adjustments (which include only normal recurring adjustments) necessary to arrive at a fair presentation of our interim results of operations. Results for the interim period ended September 30, 2004, do not necessarily indicate the results that you can expect for the year as a whole.

RISK FACTORS

        By voting in favor of the merger, Citizens stockholders will be choosing to invest in Main Street's common stock to the extent they receive Main Street common stock in exchange for any portion of their shares of Citizens common stock. In addition to the information contained elsewhere in this proxy statement-prospectus or incorporated in this proxy statement-prospectus by reference, as a stockholder of Citizens, you should carefully consider the following factors in making your decision as to how to vote on the merger.

        The exchange ratio is fixed and will not be adjusted to reflect changes in Main Street's stock value prior to the effective time of the merger.

        The merger agreement provides that each share of Citizens common stock will be converted into either 1.1051 shares of Main Street common stock or $35.00 cash. With respect to the stock portion of this consideration, the exchange ratio of 1.1051 shares of Main Street stock per share of Citizens stock is fixed and will not be adjusted to reflect any changes in the value of Main Street common stock between the date of the merger agreement and the effective time of the merger, except in the limited circumstance described below. As a result, the precise value of the total merger consideration to be paid to Citizens' shareholders will not be known at the time of the Citizens special meeting. Moreover, the value of Main Street common stock may also rise or fall after the merger. Stock price changes may result from a variety of factors, including completion of the merger, general market and economic conditions, changes in our respective businesses, operations and prospects and regulatory considerations. Many of these factors are beyond Main Street's control, and it is possible that the market value of Main Street common stock at the time of the merger and afterward may be substantially higher or lower than current market value. As a result, you will not know, either when you vote or when you make an election, the exact value of the shares of Main Street common stock that you may receive, and you are urged to obtain current market price quotations for Main Street common stock prior to taking any of these actions. However, as described in this document, if the Main Street stock price falls to below $26.92, and if Main Street's stock price performs worse than an index of stocks, Citizens may be able to terminate the merger agreement if Main Street does not elect to adjust the consideration in such a way that the per share value of the merger consideration is equal to at least $29.75.

        To preserve the treatment of the merger as a tax-free reorganization under the Internal Revenue Code, the merger agreement requires that, on an aggregate basis, taking into account appraisal shares, 50% of the Citizens shares outstanding at the effective time be converted into shares of Main Street common stock and 50% of the Citizens shares outstanding at the effective time be converted into cash. Although you will be permitted to elect the form of consideration you desire in the merger (provided that you own 100 or more Citizens shares), your elections are subject to a proration procedure that will enable Main Street to implement this 50% stock and 50% cash limitation. Accordingly, you will not know, either when you vote or when you make your election, the number of shares of Main Street common stock, or the amount of cash, that you will actually receive in the merger.

        The interests of certain management officials of Citizens may be different from those of other stockholders.

        Citizens' directors and executive officers have interests in the merger other than their interests as Citizens stockholders. These interests may cause Citizens' directors and executive officers to view the merger proposal differently than you may view it. The board of directors of Citizens was aware of these interests at the time it approved the merger. See "Description of Transaction—Interests of Certain Persons in the Merger."

21



        Difficulties in combining the operations of Citizens and Main Street may prevent the combined company from achieving the expected benefits from its acquisition.

        The combined company may not be able to achieve fully the strategic objectives and operating efficiencies it hopes to achieve in the merger. The success of the merger will depend on a number of factors, including the combined company's ability to:

These factors could contribute to the combined company not achieving the expected benefits from the merger within the desired time frames, if at all.

        Citizens has not obtained an updated fairness opinion from Sandler O'Neill reflecting changes in circumstances that may have occurred since the signing of the merger agreement.

        Citizens has not obtained an updated opinion as of the date of this document from its financial advisor, Sandler O'Neill. Changes in Citizens' operations and prospects, general market and economic conditions and other factors which may be beyond Citizens' control, and on which the fairness opinion was based, may have altered the value of Citizens or the prices of shares of Citizens common stock and shares of Main Street common stock as of the date of this document, or may alter such values and prices by the time the merger is completed. The opinion does not speak as of any date other than the date of that opinion. For a description of the opinion that Citizens received from Sandler O'Neill, please refer to "Description of Transaction—Fairness Opinion of Citizens' Financial Advisor" beginning on page    . For a description of the other factors considered by Citizens' board of directors in determining to approve the merger, please refer to "Description of Transaction—Citizens' Reasons for the Merger and Board Recommendation" beginning on page    .


A WARNING ABOUT FORWARD-LOOKING STATEMENTS

        We have each made forward-looking statements in this document (and in documents to which we refer you in this document) that are subject to risks and uncertainties. These forward-looking statements include information about possible or assumed future results of our operations or the performance of the combined company after the merger is completed. When we use any of the words "believes," "expects," "anticipates," "estimates" or similar expressions, we are making forward-looking statements. These statements are based on Main Street's and Citizens' respective management's existing expectations, which in turn are based on information that is currently available to them and on the current economic, regulatory and competitive environment, including factors such as the strength of the U.S. and local economies; federal, state and local laws, regulations and policies; interest rates and regulatory policies; and expectations as to competitors and customers. Many possible events or factors, including changes from current conditions in the factors mentioned above, could affect the future financial results and performance of each of our companies and the combined company after the merger and could cause those results or performance to differ materially from those expressed in our forward-looking statements.

22



        In addition to the factors listed above and the risks discussed in the "Risk Factors" section of this proxy statement-prospectus, factors that could have a material adverse effect on our operations and future prospects include, but are not limited to, the following:

        These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements.

        Any forward-looking earnings estimates included in this proxy statement-prospectus have not been examined or compiled by either of our independent public accountants, nor have either of our independent accountants applied any procedures to our estimates. Accordingly, our accountants do not express an opinion or any other form of assurance on them. The forward-looking statements included in this proxy statement-prospectus are made only as of the date of this proxy statement-prospectus. Further information concerning Main Street and its business, including additional factors that could materially affect Main Street's financial results, is included in Main Street's filings with the Securities and Exchange Commission. Further information concerning Citizens and its business, including additional factors that could materially affect Citizens' financial results, is included in Citizens' filings with the Securities and Exchange Commission.

INTRODUCTION

        Citizens is furnishing this proxy statement-prospectus to holders of Citizens common stock, $0.01 par value per share, in connection with the proxy solicitation by Citizens' board of directors. Citizens' board of directors will use the proxies at the special meeting of stockholders of Citizens to be held on [                        ], 2005, and at any adjournments or postponements of the meeting.

        Stockholders will be asked at this special meeting to vote to adopt the Agreement and Plan of Merger, dated as of November 7, 2004, among Citizens, Main Street and Citizens Acquisition LLC, and to approve the transactions it contemplates. Under the merger agreement, Citizens will merge into Citizens Acquisition LLC, and Citizens Acquisition LLC will be dissolved immediately after the merger. As a result, Citizens Savings Bank, which is currently a wholly-owned subsidiary of Citizens, will become a wholly-owned subsidiary of Main Street, and will continue operations under its existing name and charter. In the merger, each of the outstanding shares of Citizens common stock will be converted into the right to receive shares of Main Street common stock, cash or a combination of both, as described in this proxy statement-prospectus.


SPECIAL MEETING

Date, Place, Time and Purpose

        The special meeting of Citizens' stockholders will be held at [                        ], at [    ]:00 [    ].m. local time, on [                        ], 2005. At the special meeting, holders of Citizens common stock will be asked to vote upon a proposal to adopt the merger agreement and to approve the transactions it contemplates.

Record Date, Voting Rights, Required Vote and Revocability of Proxies

        The Citizens board fixed the close of business on [                        ], 2005, as the record date for determining those Citizens stockholders who are entitled to notice of and to vote at the special meeting. Only holders of Citizens common stock of record on the books of Citizens at the close of business on the record date have the right to receive notice of and to vote at the special meeting. On the record date, there were [                        ] shares of Citizens common stock issued and outstanding, held by approximately [            ] holders of record.

        At the special meeting, Citizens stockholders will have one vote for each share of Citizens common stock owned on the record date. The holders of a majority of the outstanding shares of Citizens common stock entitled to vote at the special meeting must be present for a quorum to exist at the special meeting.

        To determine if a quorum is present, Citizens intends to count the following:

        Approval of the merger agreement requires the affirmative vote of holders of a majority of the outstanding shares of Citizens common stock.

        Brokers who hold shares in street name for customers who are the beneficial owners of such shares may not give a proxy to vote those shares without specific instructions from their customers. Any abstention, non-voting share or "broker non-vote" will have the same effect as a vote against the approval of the merger agreement.

24



        Properly executed proxies that Citizens receives before the vote at the special meeting that are not revoked will be voted in accordance with the instructions indicated on the proxies. If no instructions are indicated, these proxies will be voted FOR the proposal to adopt the merger agreement and to approve the transactions it contemplates, and FOR any resolution to adjourn the special meeting, if necessary, to solicit additional proxies, and the proxy holder may vote the proxy in its discretion as to any other matter that may properly come before the special meeting.

        A Citizens stockholder who has given a proxy solicited by the Citizens board may revoke it at any time prior to its exercise at the special meeting by:

        All written notices of revocation and other communications with respect to revocation of proxies should be sent to: Citizens First Financial Corp., 2101 North Veterans Parkway, P.O. Box 1207, Bloomington, Illinois 61704, Attention: Dallas G. Smiley, Executive Vice President, Secretary and Treasurer.

        On the record date, Citizens' directors owned 232,250 shares, or approximately 14.82% of the outstanding shares, of Citizens common stock. These individuals have agreed to vote their shares in favor of adopting the merger agreement and approving the transactions it contemplates. However, because they hold only 14.82% of the voting power, adoption of the merger agreement and approval of the merger is not assured.

Solicitation of Proxies

        Directors, officers and employees of Citizens may solicit proxies by regular or electronic mail, in person or by telephone or facsimile. They will receive no additional compensation for these services. Citizens may make arrangements with brokerage firms and other custodians, nominees and fiduciaries, if any, for the forwarding of solicitation materials to the beneficial owners of Citizens common stock held of record by such persons. Citizens will reimburse any brokers, custodians, nominees and fiduciaries for the reasonable out-of-pocket expenses incurred by them for their services. Citizens will bear all expenses associated with the printing and mailing of this proxy statement-prospectus to its stockholders, as provided in the merger agreement. See "Description of Transaction—Expenses"

Authority to Adjourn Special Meeting to Solicit Additional Proxies

        Citizens is asking its stockholders to grant full authority for the special meeting to be adjourned, if necessary, to permit solicitation of additional proxies to approve the transactions proposed by this proxy statement-prospectus.

Appraisal Rights

        All of Citizens' stockholders have the right under Delaware law to demand appraisal of their shares and obtain cash in an amount equal to the fair value of their shares of Citizens common stock under the circumstances described below. If Citizens' stockholders fail to comply with the procedural requirements of Section 262 of the Delaware General Corporation Law, they will lose their right to demand appraisal and seek payment of the fair value of their shares.

        The fair value that Citizens' stockholders obtain for their shares by dissenting is determined by the statutory requirements of Section 262 of the Delaware General Corporation Law. This fair value may be less than, equal to or greater than the value of the cash and Main Street common stock that a stockholder would be entitled to receive under the merger agreement.

25



        The following is a summary of Section 262 of the Delaware General Corporation Law, which specifies the procedures applicable to stockholders demanding appraisal. This summary is not a complete statement of the law regarding the right to demand appraisal under Delaware law, and if you are considering demanding appraisal, we urge you to review the provisions of Section 262 carefully. The text of Section 262 is attached to this proxy statement-prospectus as Appendix C, and we incorporate that text into this proxy statement-prospectus by reference.

        To demand appraisal, you must satisfy each of the following conditions:

        If you fail to comply with any of these conditions and the merger becomes effective, you will be entitled to receive only the consideration provided in the merger agreement. Failure to vote on the merger agreement will not constitute a waiver of your appraisal rights. Voting against the merger agreement will not, by itself, satisfy the requirement of a written demand for appraisal.

        A written demand will be sufficient if it reasonably informs Citizens of the identity of the stockholder and that the stockholder intends to demand an appraisal of his or her shares. All written demands for appraisal should be addressed to: Citizens First Financial Corp., 2101 North Veterans Parkway, P.O. Box 1207, Bloomington, Illinois 61704, Attention: Dallas G. Smiley, Executive Vice President, Secretary and Treasurer. The demands must be received before the vote at the special meeting concerning the merger agreement occurs, and should be executed by, or on behalf of, the holder of record.

        To be effective, a demand for appraisal must be executed by or for the stockholder of record who holds the shares, fully and correctly, as the stockholder's name appears on his or her stock certificates. If Citizens shares are owned of record in a fiduciary capacity, as by a trustee, guardian or custodian, execution of a demand for appraisal should be made in that capacity. If Citizens shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or for all joint owners. An authorized agent, including one for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for the record owner. A record owner, such as a broker or trustee, who holds Citizens shares as a nominee for others may exercise his or her rights of appraisal with respect to the shares held for one or more beneficial owners, while not exercising such right for other beneficial owners. In that case, the written demand should set forth the number of shares as to which the record owner dissents. Where no number of shares is expressly mentioned, the demand will be presumed to cover all shares of Citizens shares in the name of that record owner.

        At any time within the 60-day period after the effective time, a stockholder may withdraw his or her demand for appraisal. If he or she does so, that stockholder will be treated as having accepted the terms offered in the merger. After the permissive 60-day withdrawal period, a stockholder may withdraw an appraisal demand only with Main Street's consent.

        Within 10 days after the merger, Main Street must give written notice that the merger has become effective to each holder of Citizens shares who filed a written demand for appraisal and who did not

26



vote in favor of the merger agreement. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of the notice, demand in writing from Main Street the appraisal of his or her Citizens shares. Within 120 days after the completion of the merger, either Main Street or any Citizens stockholder who has complied with Section 262 may file a petition in the Delaware Court of Chancery demanding a determination of the value of the Citizens shares held by all stockholders entitled to appraisal of their shares. Main Street does not presently intend to file such a petition. Because Main Street has no obligation to file such a petition, the failure of a stockholder to do so within the period specified could nullify the stockholder's previous written demand for appraisal.

        If a petition for appraisal is duly filed by a stockholder and a copy is delivered to Main Street, Main Street will then be obligated within 20 days of receipt of the copy to provide the Court of Chancery with a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreement as to the value of their shares has not been reached. After notice to these stockholders, the Court of Chancery is empowered to conduct a hearing to determine which stockholders are entitled to appraisal rights.

        The Court of Chancery will then appraise the Citizens shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger. When the value is determined, the Court will direct the payment by Main Street of this value, with interest thereon, simple or compound, if the Court so determines, to the stockholders entitled to receive this money.

        Stockholders of Citizens who are considering seeking an appraisal should bear in mind that the fair value of their Citizens shares as determined under Section 262 could be more than, the same as or less than the merger consideration they are entitled to receive pursuant to the merger agreement if they do not seek appraisal of their shares.

        Costs of the appraisal proceeding may be assessed against the stockholder by the court as the court deems equitable in the circumstances. From and after the effective date of the merger, no stockholder who has demanded appraisal rights shall be entitled to vote his or her stock for any purpose or to receive payment of dividends or other distributions (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger).

        Failure to comply strictly with these procedures will cause you to lose your appraisal rights. Consequently, if you desire to exercise your appraisal rights, you are urged to consult a legal advisor before attempting to exercise these rights.

Recommendation of Citizens' Board

        The Citizens board has unanimously approved the merger agreement and the transactions it contemplates and believes that the proposal to adopt the merger agreement and approve the transactions it contemplates are in the best interests of Citizens and its stockholders. The Citizens board unanimously recommends that the Citizens stockholders vote FOR adoption of the merger agreement and approval of the transactions it contemplates and FOR any resolution to adjourn the special meeting, if necessary, to solicit additional proxies. See "Description of TransactionCitizens' Reasons for the Merger and Board Recommendation."

DESCRIPTION OF TRANSACTION

        The following information describes material aspects of the merger and related transactions. This description does not provide a complete description of all the terms and conditions of the merger agreement. It is qualified in its entirety by the Appendices to this document, including the merger agreement, which is attached as Appendix A to this proxy statement-prospectus and which is incorporated into this proxy statement-prospectus by reference. We urge you to read the Appendices in their entirety.

General

        The merger agreement provides for the acquisition by merger of Citizens by Main Street. At the time the merger becomes effective, each share of Citizens common stock then issued and outstanding will be converted into and exchanged for the right to receive shares of Main Street common stock, cash or a combination of both, as described below.

Merger Consideration

        Under the merger agreement, Citizens stockholders will have the right to receive, for each share of Citizens common stock that they own as of the effective time of the merger, either 1.1051 shares of Main Street common stock or $35.00 in cash.

        Election of Merger Consideration.    Stockholders owning 100 or more shares of Citizens common stock may elect to receive their share of the merger consideration entirely in Main Street common stock, entirely in cash or in a combination of Main Street common stock and cash. However, all stockholder elections are subject to the requirement that, on an aggregate basis, 50% of the Citizens shares outstanding at the effective time up to the merger must be converted into the right to receive Main Street common stock and the remaining 50% of the Citizens shares outstanding at the effective time of the merger will be converted into the right to receive cash. This requirement exists to preserve the tax treatment of the merger. Stockholders who hold less than 100 shares of Citizens common stock cannot make an election and will receive only cash consideration. In addition, Citizens stockholders who elect to receive a combination of cash and stock may not elect to receive stock with respect to fewer than 100 shares of their Citizens common stock.

        If you own 100 or more shares of Citizens common stock and do not make any election, you will receive consideration in the form of either cash or Main Street common stock in proportions necessary to satisfy the total consideration requirement, as described below.

        We are not making any recommendation as to whether Citizens stockholders should elect to receive 100% Main Street common stock, 100% cash or a combination of both. We are not making any recommendation as to whether Citizens stockholders should elect to receive a specific ratio of cash and Main Street common stock. Each Citizens stockholder must make his or her own decision with respect to the election to receive Main Street common stock, cash or a combination of both for their shares of Citizens stock.

        Variable Amount of Cash and Stock.    By the terms of the merger agreement, 50% of the total outstanding shares of Citizens common stock, taking into account appraisal shares, must be converted into cash and 50% must be converted into shares of Main Street common stock.

        If after taking into account all valid elections more than 50% of the total outstanding shares of Citizens common stock would be converted into cash, including appraisal shares, then any Citizens stockholders who elected to receive any portion of the merger consideration in cash and Citizens stockholders who did not make an election will be subject to a proration process that will result in the holder receiving additional shares of Main Street common stock in lieu of some cash. This proration will result in a final prorated number of shares of Main Street common stock being issued with a value equal to 50% of the total merger consideration.

28



        Similarly, if after taking into account all valid elections more than 50% of the total outstanding shares of Citizens common stock would be converted into Main Street common stock, then all Citizens stockholders who did not make an election will be entitled to receive only cash, and any Citizens stockholders who elected to receive any portion of the merger consideration in Main Street common stock will, if necessary, be subject to a proration process that will result in the holder receiving more cash in lieu of some Main Street common stock. This proration will result in a final prorated amount of cash paid in connection with the merger equaling 50% of the total merger consideration.

        Value of Merger Consideration.    Citizens may have a maximum of 1,761,311 shares of common stock issued and outstanding immediately prior to the merger. Based on the exchange ratio of 1.1051 shares of Main Street common stock per share of Citizens common stock, and taking into account the requirement that, on an aggregate basis, 50% of the outstanding shares of Citizens common stock be converted into Main Street common stock and 50% of the outstanding shares of Citizens common stock be converted into cash, and assuming no appraisal rights are exercised for purposes of this example, Main Street will pay total cash consideration of $30,822,942.50, and will issue 973,212 shares of Main Street common stock in the merger, calculated as follows:

        The 973,212 shares of Main Street common stock that may be issued in the merger represent approximately [    ]% of the total number of Main Street common shares that will be outstanding after the merger. The number of shares actually issued may vary, depending on the actual number of shares outstanding at the effective time of the merger and the number of Citizens shares whose holders exercise appraisal rights.

        Because the exchange ratio of 1.1051 shares of Main Street common stock is fixed, the value of the stock portion of the merger consideration will fluctuate as the price of Main Street common stock changes. You should obtain current market price quotations for Main Street common stock to determine the current value of the stock portion of the merger consideration. Based on the $[            ] closing price of Main Street common stock on [                        ], 2005, the value of the stock portion of the merger consideration is $[                        ] (973,212 shares, multiplied by $[            ]).

        The merger agreement allows Citizens to terminate the merger agreement if both:

However, before Citizens may terminate on this basis, Main Street has the right to increase the value of the cash or to change the exchange ratio in such a way that the per-share value of the merger consideration to be received by Citizens stockholders equals at least $29.75.

        Main Street will not issue any fractional shares in the merger. Instead, Main Street will pay to each Citizens stockholder who would otherwise be entitled to receive a fractional share of Main Street common stock an amount in cash, without interest, determined by multiplying such fraction by $31.67.

Election Procedures; Surrender of Stock Certificates

        Shortly after the merger, an election form will be mailed to every Citizens stockholder that holds more than 100 shares of Citizens common stock. Citizens stockholders can use this election form to elect the proportion of shares of Main Street common stock and cash that they would like to receive in exchange for their shares of Citizens common stock. Citizens stockholders do not need to make an

29



election. If no election is made, a Citizens stockholder will receive cash or Main Street common stock in such amounts that will enable us to satisfy the requirement that 50% of the Citizens shares be converted into Main Street common stock and 50% of the Citizens shares, including shares with respect to which stockholders have asserted their appraisal rights under the Delaware General Corporation Law, be converted into cash.

        To make an effective election, you must submit a properly completed election form to Main Street Bank & Trust, which will act as the exchange agent, on or before the election deadline of 5:00 p.m., Champaign, Illinois time, on [                        ], 2005. You may change your election at any time prior to the election deadline by written notice accompanied by a properly completed and signed, revised election form received by the exchange agent prior to the election deadline. All elections will be revoked automatically if the merger is not approved or the merger agreement is otherwise terminated.

        Citizens stockholders who hold less than 100 shares of Citizens stock will be entitled to receive only cash for their shares. Therefore, these stockholders will not receive an election form.

        Shortly after the merger, all Citizens stockholders will receive a letter of transmittal, together with a return envelope. The letter of transmittal will include instructions for the surrender and exchange of certificates representing Citizens common stock for the merger consideration. A letter of transmittal will be deemed properly completed only if signed and accompanied by stock certificates representing all shares of Citizens common stock or an appropriate guarantee of delivery of the certificates.

        Until you surrender your Citizens stock certificates for exchange after completion of the merger, you will not be paid dividends or other distributions declared after the merger with respect to any Main Street common stock into which your Citizens shares have been converted. When Citizens stock certificates are surrendered, Main Street will pay to the surrendering holder any of his or her respective unpaid dividends or other distributions, without interest. After the completion of the merger, no further transfers of Citizens common stock will be permitted. Citizens stock certificates presented for transfer after the completion of the merger will be canceled and exchanged for the merger consideration.

        No fractional shares of Main Street common stock will be issued to any holder of Citizens common stock upon consummation of the merger. For each fractional share that would otherwise be issued, Main Street will pay cash in an amount equal to $31.67 per whole share. No interest will be paid or accrued on cash payable to holders of Citizens common stock in lieu of fractional shares. No stockholder of Citizens will be entitled to dividends, voting rights or any other rights as a stockholder of Main Street in respect of any fractional shares.

        None of Main Street, Citizens or any other person will be liable to any former holder of Citizens common stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

        If a certificate for Citizens common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration properly payable under the merger agreement upon compliance by the holder of Citizens common stock with the conditions reasonably imposed by the exchange agent. These conditions will include a requirement that the stockholder provide a lost instruments indemnity bond in form, substance and amount reasonably satisfactory to the exchange agent and Main Street.

Effective Time of the Merger

        Subject to the conditions to each party's obligations to complete the merger, the merger will become effective when a certificate of merger reflecting the merger is filed with the Secretary of State of the State of Delaware. Unless we agree otherwise, each party will use reasonable efforts to cause the merger to become effective 10 business days after the later to occur of:

30


        We anticipate that the merger will become effective in the second quarter of 2005, however, delays could occur.

        We cannot assure you that the necessary stockholder and regulatory approvals of the merger will be obtained or that other conditions precedent to the merger can or will be satisfied. Either party's board of directors may terminate the merger agreement if the merger is not completed by September 7, 2005, unless it is not completed because of the failure by the party seeking termination to comply fully with its obligations under the merger agreement. See "—Conditions to Completion of the Merger" and "—Termination and Termination Fees."

United States Federal Income Tax Consequences of the Merger

        The following is a summary of the material United States federal income tax consequences of the merger generally applicable to Citizens stockholders. This discussion assumes you hold your shares of Citizens common stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code, and does not address all aspects of United States federal income taxation that may be relevant to you in light of your particular circumstances or if you are subject to special rules, such as rules relating to:

        In addition, this summary does not address any state, local or foreign tax consequences of the merger that may apply. The following discussion is based on the Code, existing and proposed regulations promulgated under the Code, published Internal Revenue Service rulings and court decisions, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. Any such change could affect the continuing validity of this discussion.

        Tax Consequences of the Merger Generally.    It is intended that the merger of Citizens with and into Citizens Acquisition LLC, will be treated as a reorganization within the meaning of Section 368(a) of the Code. Main Street's and Citizens' obligations to complete the merger are conditioned on, among other things, their receipt of an opinion from Barack Ferrazzano Kirschbaum Perlman & Nagelberg LLP dated as of the date of the registration statement filed with the Securities and Exchange Commission in connection with the merger and updated through the effective date, to the effect that:

31


        The opinion of Barack Ferrazzano Kirschbaum Perlman & Nagelberg LLP will be based upon existing law, assumes the absence of changes in existing facts, relies upon customary assumptions and relies upon representations contained in certificates executed by officers of Main Street and Citizens. The opinion neither binds the Internal Revenue Service nor precludes it from adopting a contrary position, and it is possible that the Internal Revenue Service may successfully assert a contrary position in litigation or other proceedings. Neither Main Street nor Citizens intends to obtain a ruling from the Internal Revenue Service with respect to the tax consequences of the merger.

        The following discussion assumes that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code.

        Citizens Stockholders Who Receive Only Main Street Common Stock.    If you are a holder of Citizens common stock and you receive only Main Street common stock (plus any cash in lieu of a fractional share of Main Street common stock) in exchange for your Citizens common stock in the merger, you will not recognize any gain or loss for federal income tax purposes with respect to such exchange, except with respect to any cash received in lieu of a fractional share, as discussed below.

        Citizens Stockholders Who Receive Both Main Street Common Stock and Cash.    If you are a holder of Citizens common stock and you receive both Main Street common stock and cash (other than cash received in lieu of a fractional share of Main Street common stock) in exchange for your Citizens common stock in the merger, you will recognize gain, but not loss, in an amount equal to the lesser of:

        Any such gain will be treated as capital gain unless the receipt of the cash has the effect of a distribution of a dividend for federal income tax purposes, in which case the gain will be treated as ordinary dividend income to the extent of your ratable share of Citizens' accumulated earnings and profits. Any capital gain will be long-term capital gain if, as of the date of the merger, your holding period in your Citizens common stock is greater than one year.

        The stock redemption provisions of Section 302 of the Code apply in determining whether cash received by you in exchange for your Citizens common stock has the effect of a distribution of a dividend under Section 356(a)(2) of the Code, which we refer to as a hypothetical redemption analysis. Under the hypothetical redemption analysis, you will be treated as if that portion of your Citizens common stock that you exchange for cash in the merger will instead be exchanged for Main Street common stock (which we call the hypothetical shares) followed immediately by a redemption of the hypothetical shares by Main Street for cash. Under the principles of Section 302 of the Code, you will recognize capital gain rather than dividend income with respect to the cash received if the hypothetical redemption is "not essentially equivalent to a dividend" or is "substantially disproportionate" with respect to you. In applying the principles of Section 302 of the Code, the constructive ownership rules of Section 318 of the Code will apply in comparing your ownership interest in Main Street both immediately after the merger (but before the hypothetical redemption) and after the hypothetical redemption.

        If you are a holder of Citizens common stock, whether the hypothetical redemption by Main Street of the hypothetical shares for cash is "not essentially equivalent to a dividend" will depend on your particular circumstances. However, the hypothetical redemption must, in any event, result in a "meaningful reduction" in your percentage ownership of Main Street common stock. In determining whether the hypothetical redemption by Main Street results in a meaningful reduction in your

32



percentage ownership of Main Street common stock and, therefore, does not have the effect of a distribution of a dividend, you should compare your interest in Main Street (including interests owned actually, hypothetically, and constructively) immediately after the merger (but before the hypothetical redemption) to your interest after the hypothetical redemption. The Internal Revenue Service has indicated in Revenue Ruling 76-385 that a stockholder in a publicly-held corporation whose relative stock interest in the corporation is minimal and who exercises no "control" over corporate affairs is generally treated as having had a meaningful reduction in his or her stock after a redemption transaction if his or her percentage stock ownership in the corporation has been reduced to any extent, taking into account the stockholder's actual and constructive ownership before and after the hypothetical redemption.

        If you are a holder of Citizens common stock, the hypothetical redemption transaction would be "substantially disproportionate" and, therefore, would not have the effect of a distribution of a dividend if you own less than 50 percent of the voting power of the outstanding Main Street common stock and the percentage of Main Street common stock actually and constructively owned by you immediately after the hypothetical redemption is less than 80 percent of the percentage of Main Street common stock actually, hypothetically and constructively owned by you immediately before the hypothetical redemption. Nevertheless, you should consult your own tax advisor about the possibility that all or a portion of any cash received in exchange for Citizens common stock will be treated as a dividend.

        Tax Basis and Holding Period.    The aggregate tax basis of any Main Street common stock you receive as a result of the merger will be the same as your aggregate tax basis in the Citizens common stock you surrender in exchange for the Main Street common stock, decreased by the amount of cash received in the merger, and increased by the amount of income or gain recognized in the merger. Your holding period for the Main Street common stock you receive as a result of the exchange will include the period during which you held the Citizens common stock you surrender in the merger.

        Cash Received in Lieu of Fractional Shares.    If you receive cash in the merger instead of a fractional share of Main Street common stock, you will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption of the fractional share by Main Street. Assuming that immediately after the merger you hold a minimal interest in Main Street, you exercise no control over Main Street and, as a result of the deemed redemption and after giving effect to certain constructive ownership rules, you experience an actual reduction in your interest in Main Street, you will generally recognize capital gain or loss on the deemed redemption in an amount equal to the difference between the amount of cash received and your adjusted tax basis allocable to such fractional share. This capital gain or loss will be long-term capital gain or loss if, as of the effective date of the merger, you held your shares of Citizens common stock for more than one year. Long-term capital gain of a non-corporate United States stockholder is generally subject to a maximum federal tax rate of 15%. The deductibility of capital losses is subject to limitations.

        Backup Withholding and Information Reporting.    Unless you provide a taxpayer identification number (social security number or employer identification number) and certify, among other things, that such number is correct, or you provide proof of an applicable exemption from backup withholding, the exchange agent will be required to withhold 28% of any cash payable to you in connection with the merger. Any amount so withheld under the backup withholding rules is not an additional tax and will be allowed as a refund or credit against your United States federal income tax liability, provided that you furnish the required information to the Internal Revenue Service. You should complete and sign the substitute Form W-9 (included as part of the transmittal letter that accompanies the election form) to provide the information and certification necessary to avoid backup withholding, unless an applicable exception exists and is established in a manner that is satisfactory to the exchange agent.

        You will be required to retain records pertaining to the merger and will be required to file a statement with your United States federal income tax return for the taxable year in which the merger

33



takes place that sets forth certain facts relating to the merger, including your basis in your Citizens common stock that you surrender in connection with the merger and the fair market value of the Main Street common stock and/or cash that you receive in connection with the merger. In addition, pursuant to the American Jobs Creation Act of 2004, Main Street (or, if required by to-be-published regulations, Citizens) will be required to provide to the Internal Revenue Service and Citizens stockholders information with respect to the merger, including information regarding your identity (and the identities of other Citizens stockholders) and the amount of cash and the fair market value of Main Street common stock received by you (and by each other Citizens stockholder) in the merger.

        The foregoing discussion is not intended to be a complete analysis or description of all potential federal income tax consequences of the merger. In addition, the discussion does not address tax consequences which may vary with, or are contingent on, your individual circumstances. Moreover, the discussion does not address any non-income tax or any foreign, state, or local tax consequences of the merger. Accordingly, you are strongly urged to consult with your own tax advisor to determine the particular federal, state, local and foreign income and other tax consequences to you of the merger.

Background of the Merger

        Citizens was formed in 1996 when Citizens Savings Bank was converted from mutual to stock form. In 1999, Citizens Savings Bank was converted from a federal charter to an Illinois charter. Since 1999, Citizens Savings Bank has operated as a community oriented, Illinois-chartered, savings bank. Citizens Savings Bank's main objectives have been to attract deposits from the general public and to use such deposits to invest primarily in residential and commercial real estate loans and commercial business loans.

        The management and board of directors of Citizens have continually monitored the financial service industry's evolution that has required increasing investments in technology to remain competitive and to satisfy regulatory imperatives. Management and the board have been concerned about the ability of Citizens to remain competitive in the central Illinois banking market. The board of directors has also been aware of the trend towards consolidation in the industry and has periodically reviewed and discussed the strategic alternatives available to Citizens.

        From time-to-time throughout Citizens' existence, at various banking industry functions, C. William Landefeld, Citizens' President and Chief Executive Officer, received informal, passing indications of interest from executive officers of other financial institutions to the effect that they might be interested if Citizens ever determined to sell. Because Citizens' plan was to remain independent, no action was taken by or on behalf of Citizens or any third party in response to any of these comments. In March 2003, Mr. Landefeld received a telephone call from Whitley A. Cummings, a well-known financial advisor with McConnell, Budd and Romano, Inc., inquiring whether Mr. Landefeld would be willing to have a "get-to-know-you" meeting with two of the executive officers of Main Street, Van A. Dukeman and Gregory B. Lykins. Mr. Landefeld agreed and the parties held a short meeting at Citizens' offices attended by Mr. Landefeld, Mr. Dukeman, Mr. Lykins, and Dallas Smiley, Chief Financial Officer of Citizens. The parties met for lunch or had similar meetings on three other occasions in mid-to-late 2003 and discussed the general state of the industry and banking developments. At no time did the parties discuss a merger or other possible affiliation.

        In June 2004, representatives of Sandler O'Neill were contacted by Mr. Lykins of Main Street to express Main Street's interest in a possible business combination with Citizens and to request that Sandler O'Neill contact Citizens to arrange a preliminary meeting on that subject. Sandler O'Neill contacted Mr. Landefeld who agreed to meet with Main Street and a meeting was arranged for later that month. At that meeting, which was attended by Messrs. Landefeld, Smiley, Dukeman and Lykins, Main Street informally expressed an interest in affiliating with Citizens. As a result of the June 2004 meeting, Mr. Landefeld brought the matter to the attention of the board of directors at Citizens' June 2004 meeting.

34



        At its meeting on June 28, 2004, which was attended by Sandler O'Neill, the board of directors of Citizens began discussions concerning strategic planning alternatives available to Citizens which might include a possible business combination with a larger financial institution, including, but not limited to Main Street. Sandler O'Neill discussed with the board Main Street's possible reasons for an affiliation. The board authorized management to retain Sandler O'Neill to assist it in its strategic planning and to discuss with Main Street the terms and conditions of a possible affiliation, including the amount of the purchase price.

        During the second week of July 2004, Citizens and Main Street entered into a confidentiality agreement and exchanged basic documents and financial statements. During the second week of August 2004, Sandler O'Neill met with members of Main Street's senior management to discuss Main Street's interest in a business combination with Citizens. During the first week of September 2004, Main Street provided Sandler O'Neill verbally with a preliminary range of prices of $30.00 - $31.00 per share for each share of Citizens common stock, subject to the results of its due diligence review and other factors.

        At a meeting held on September 7, 2004, Sandler O'Neill reported to the board the results of its preliminary discussions with Main Street, including Main Street's preliminary pricing proposal. After discussion, the board directed Sandler O'Neill to report to Main Street that their pricing proposal was not at an appropriate level and to seek a higher proposal. Following those discussions, in late September, 2004, Main Street indicated that it was interested in pursuing a potential business combination with Citizens at a purchase price of $35 per share. The expression of interest was not complete regarding the form of merger consideration and was conditioned upon the satisfactory completion of due diligence. At its meeting on September 27, 2004, the Citizens board of directors authorized management and its professional advisors to pursue further discussions with Main Street.

        From October 5 through October 8, 2004, Main Street and its advisor conducted a due diligence review of Citizens. On November 2, 2004, Citizens and its advisor, along with representatives from BKD, LLP, conducted a due diligence review of Main Street.

        On November 1, 2004, the Citizens board of directors met to discuss in detail a transaction with Main Street. At that meeting, the board of directors of Citizens authorized management, together with its advisors, to negotiate the terms of a merger agreement between Main Street and Citizens. Citizens' legal counsel, Howard & Howard Attorneys, P.C., discussed with the board its fiduciary obligations in considering such a proposal.

        On November 3, 2004, the board of directors of Main Street reviewed with their legal counsel the terms of the proposed merger agreement with Citizens. After discussion with Main Street's legal and financial advisors and among the members of the board, the Main Street board of directors approved the merger agreement and the merger, and authorized its officers to execute the merger agreement on behalf of Main Street.

        On November 5, 2004, the board of directors of Citizens received a draft of the proposed merger agreement for review. On November 7, 2004, the board of directors of Citizens considered the proposed merger agreement between Citizens and Main Street. Howard & Howard reviewed with the board the terms of the proposed agreement. At that meeting, the board also received an opinion from Sandler O'Neill that, as of that date and subject to certain assumptions and limitations on review, the consideration to be received by Citizens' stockholders in the merger was fair, from a financial point of view, to those stockholders. The directors asked additional questions concerning the terms of the transaction and the possible effect on stockholders. After the conclusion of this review and additional discussion, the Citizens board approved the merger and authorized its officers to execute the merger agreement on behalf of Citizens.

35


        Citizens and Main Street signed the merger agreement as of November 7, 2004. On Monday, November 8, 2004, Citizens and Main Street issued a joint press release announcing the execution of the agreement.

Main Street's Reasons for the Merger

        The board of directors of Main Street believes that the merger presents a unique opportunity to combine two of central Illinois' strongest franchises to create a premier banking and financial services company with the capability of offering a full range of financial products and services in many of central Illinois' most attractive markets through an extensive distribution network.

        In reaching its decision to adopt the merger agreement and approve the merger, the board of directors of Main Street consulted with Main Street's management, as well as with its legal counsel and financial advisor, and considered a variety of factors, including the following:

36


        The foregoing discussion of the information and factors considered by the board of directors of Main Street is not intended to be exhaustive, but includes all material factors considered by the board of directors of Main Street. In reaching its determination to approve the merger, the board of directors of Main Street did not assign any relative or specific weights to the foregoing factors, and individual directors may have given differing weights to different factors.

Citizens' Reasons for the Merger and Board Recommendation

        The Citizens board believes that the merger is fair to, and in the best interests of, Citizens and the Citizens stockholders. Accordingly, the Citizens board has unanimously approved the merger agreement and unanimously recommends that the Citizens stockholders vote FOR the adoption of the merger agreement and approval.

        The Citizens board believes that the consummation of the merger presents a unique opportunity to combine with one of central Illinois' premier community banking franchises to aid in the creation of an even stronger central Illinois' financial services company with truly local decision-making authority.

        In reaching its decision to approve the merger agreement, the Citizens board consulted with Citizens' management, as well as with its financial and legal advisors, and considered a variety of factors, including the following:

37


        The foregoing discussion of the information and factors considered by the Citizens board is not intended to be exhaustive, but includes all material factors considered by the Citizens board. In reaching its determination to approve and recommend the merger, the Citizens board did not assign any relative or specific weights to the foregoing factors, and individual directors may have given differing weights to different factors. The Citizens board is unanimous in its recommendation that Citizens stockholders vote for approval and adoption of the merger agreement.

Fairness Opinion of Citizens' Financial Advisor

        By letter dated June 30, 2004, Citizens retained Sandler O'Neill to act as its financial advisor. Sandler O'Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O'Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

        Sandler O'Neill acted as financial advisor to Citizens in connection with the proposed merger and participated in certain of the negotiations leading to the merger agreement. At the November 7, 2004 meeting at which Citizens' board considered and approved the merger agreement, Sandler O'Neill delivered to the board its oral opinion, subsequently confirmed in writing that, as of such date, the merger consideration was fair to Citizens' shareholders from a financial point of view. The full text of Sandler O'Neill's opinion is attached as Appendix B to this proxy statement-prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O'Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the opinion. Sandler O'Neill urges Citizens shareholders to read the entire opinion carefully in connection with their consideration of the proposed merger.

38



        Sandler O'Neill's opinion speaks only as of the date of the opinion. The opinion was directed to the Citizens board and is directed only to the fairness of the merger consideration to Citizens shareholders from a financial point of view. It does not address the underlying business decision of Citizens to engage in the merger or any other aspect of the merger and is not a recommendation to any Citizens shareholder as to how such shareholder should vote at the special meeting with respect to the merger or any other matter.

        In connection with rendering its opinion, Sandler O'Neill reviewed and considered, among other things:

        Sandler O'Neill also discussed with certain members of senior management of Citizens the business, financial condition, results of operations and prospects of Citizens and held similar discussions with certain members of senior management of Main Street regarding the business, financial condition, results of operations and prospects of Main Street. In connection with our engagement, Sandler O'Neill was not asked to, and did not, solicit indications of interest in a potential transaction from third parties.

        In performing its reviews and analyses and in rendering its opinion, Sandler O'Neill relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided by Citizens or Main Street or their respective representatives or that was otherwise reviewed by Sandler O'Neill and have assumed such accuracy and completeness for purposes of rendering this opinion. Sandler O'Neill further relied on the assurances of management of Citizens and Main Street that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Sandler O'Neill has not been asked to and has not

39



undertaken an independent verification of any of such information and Sandler O'Neill does not assume any responsibility or liability for the accuracy or completeness thereof. Sandler O'Neill did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Citizens or Main Street or any of their subsidiaries, or the collectibility of any such assets, nor has Sandler O'Neill been furnished with any such evaluations or appraisals. Sandler O'Neill did not make an independent evaluation of the adequacy of the allowance for loan losses of Citizens or Main Street nor has Sandler O'Neill reviewed any individual credit files relating to Citizens or Main Street. Sandler O'Neill assumed, with Citizens' consent, that the respective allowances for loan losses for both Citizens and Main Street are adequate to cover such losses.

        Sandler O'Neill's opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of its opinion. Sandler O'Neill assumed, in all respects material to its analysis, that all of the representations and warranties contained in the merger agreement and all related agreements are true and correct, that each party to such agreements will perform all of the covenants required to be performed by such party under such agreements and that the conditions precedent in the merger agreement are not waived. Sandler O'Neill also assumed, with Citizens' consent, that there has been no material change in Citizens' and Main Street's assets, financial condition, results of operations, business or prospects since the date of the last financial statements made available to them, that Citizens and Main Street will remain as going concerns for all periods relevant to its analyses, and that the merger will qualify as a tax-free reorganization for federal income tax purposes. Finally, with Citizens' consent, Sandler O'Neill relied upon the advice Citizens received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement.

        In rendering its November 7, 2004 opinion, Sandler O'Neill performed a variety of financial analyses. The following is a summary of the material analyses performed by Sandler O'Neill, but is not a complete description of all the analyses underlying Sandler O'Neill's opinion. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O'Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O'Neill's comparative analyses described below is identical to Citizens or Main Street and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of Citizens or Main Street and the companies to which they are being compared.

        The earnings projections used and relied upon by Sandler O'Neill in its analyses for Citizens and Main Street for the years ending December 31, 2004 and 2005 were published by I/B/E/S and reviewed by and confirmed with management of Citizens. These estimates and all projections of transaction costs, purchase accounting adjustments and expected cost savings relating to the merger were reviewed with the senior managements of Main Street and Citizens, and Sandler O'Neill assumed for purposes of its analyses that they reflected the best currently available estimates and judgments of such managements of the future financial performance of Citizens and Main Street, respectively, and that such performances would be achieved. Sandler O'Neill expressed no opinion as to such financial projections or the assumptions on which they were based. These projections, as well as the other estimates used by Sandler O'Neill in its analyses, were based on numerous variables and assumptions

40



which are inherently uncertain and, accordingly, actual results could vary materially from those set forth in such projections.

        In performing its analyses, Sandler O'Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Citizens, Main Street and Sandler O'Neill. The analyses performed by Sandler O'Neill are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. Sandler O'Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Citizens board at the board's November 7 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O'Neill's analyses do not necessarily reflect the value of Citizens' common stock or Main Street's common stock or the prices at which Citizens' or Main Street's common stock may be sold at any time.

        Summary of Proposal.    Sandler O'Neill reviewed the financial terms of the proposed transaction. Assuming that the fixed exchange ratio of 1.1051 was applied to $31.67 (the average of the bid/ask prices of Main Street's common stock on November 4, 2004) and that 50% of CFSB's shares are exchanged for shares of Main Street common stock and that the remaining 50% are purchased for $35.00 in cash, Sandler O'Neill calculated an implied transaction value of $35.00 per share. Based upon per-share financial information for Citizens for the twelve months ended September 30, 2004, Sandler O'Neill calculated the following ratios:

Transaction Ratios      
Transaction value/Last 12 months' EPS   33.3 x
Transaction value/Estimated 2004 EPS(1)   20.0 x
Transaction value/Estimated 2005 EPS(1)   19.4 x
Transaction value/Tangible book value per share   153 %
Transaction value/Stated book value per share   153 %
Tangible book premium/Deposits(2)   7.9 %
Tangible book premium/Core deposits(3)   9.1 %

(1)
Based upon I/B/E/S estimates, reviewed with and confirmed by management

(2)
Assumes Citizens' total deposits are $231.4 million.

(3)
Assumes Citizens' total core deposits are $201.7 million.

        For purposes of Sandler O'Neill's analyses, earnings per share were based on fully diluted earnings per share. The aggregate transaction value was approximately $58.3 million, based upon 1,498,600 shares of Citizens common stock outstanding and including the intrinsic value of options to purchase an aggregate of 262,100 shares of common stock with a weighted average strike price of $12.87. Sandler O'Neill noted that the transaction value represented a 20.7% premium over the November 4, 2004 closing value of Citizens' common stock, and a 45.7% premium over the October 1, 2004 closing value of Citizens' common stock.

41


        Sandler O'Neill reviewed the history of the reported trading prices and volume of Citizens' and Main Street's common stock for the one-year and three-year periods ended November 4, 2004 and compared the relationship between the movements in the prices of Citizens' and Main Street's common stock to movements in the prices of the Nasdaq Bank Index, S&P Bank Index, S&P 500 Index and the weighted average (by market capitalization) performance of composite peer groups of publicly traded Midwest savings and commercial banking institutions selected by Sandler O'Neill for Citizens and Main Street, respectively. Over the one and three-year periods ended November 4, 2004, Citizens outperformed all of the indices and the peer group to which it was compared.

        Analysis of Selected Merger Transactions.    Sandler O'Neill reviewed 20 merger transactions announced nationwide from January 1, 2004 through November 4, 2004 involving thrift institutions as acquired institutions with announced transaction values between $15 million and $100 million. Sandler O'Neill also reviewed 15 merger transactions announced in the Midwest from January 1, 2002 through November 4, 2004 involving thrift institutions as acquired institutions with transaction values between $15 million and $100 million. Sandler O'Neill reviewed the multiples of transaction price at announcement to last twelve months' earnings per share, transaction price to book value per share, transaction price to tangible book value per share, tangible book premium to deposits, tangible book premium to core deposits and premium to market price and computed mean and median multiples and premiums for the transactions. The median multiples from the nationwide group and the median multiples for the Midwestern group were applied to Citizens' financial information as of and for the twelve months ended September 30, 2004. As illustrated in the following table, Sandler O'Neill derived imputed ranges of values per share of Citizens' common stock of $21.23 to $44.23 based upon the median multiples for the nationwide group and $25.99 to $41.71 based upon the median multiples for the thrift transactions in the Midwestern group.

        Discounted Dividend Stream and Terminal Value Analysis.    Sandler O'Neill performed an analysis that estimated the future stream of after-tax dividend flows of Citizens through December 31, 2007 under various circumstances, assuming Citizens' projected dividend stream and that Citizens performed in accordance with the I/B/E/S earnings projections reviewed with and confirmed by management. For periods after 2005, Sandler O'Neill assumed an annual growth rate of earnings per share of approximately 6%. To approximate the terminal value of Citizens common stock at December 31, 2007, Sandler O'Neill applied price/earnings multiples ranging from 12x to 22x and multiples of tangible book value ranging from 100% to 200%. The dividend income streams and terminal values were then discounted to present values using different discount rates ranging from 9.0% to 12.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Citizens common stock. As illustrated in the following tables, this analysis indicated an imputed range of values per share of Citizens common stock of $16.64 to $32.80 when applying the price/earnings multiples and $19.28 to $41.41 when applying multiples of tangible book value.

        In addition, Sandler O'Neill performed an analysis that estimated the future stream of after-tax dividend flows of Main Street through December 31, 2007 under various circumstances, assuming Main Street's projected dividend stream and that Main Street performed in accordance with the I/B/E/S earnings projections reviewed with and confirmed by management. For periods after 2005, Sandler O'Neill assumed an annual growth rate of earnings per share of approximately 8%. To approximate the

46



terminal value of Main Street common stock at December 31, 2007, Sandler O'Neill applied price/earnings multiples ranging from 14x to 24x and multiples of tangible book value ranging from 200% to 325%. The dividend income streams and terminal values were then discounted to present values using different discount rates ranging from 8.5% to 11.5% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Main Street common stock. As illustrated in the following tables, this analysis indicated an imputed range of values per share of Main Street common stock of $22.13 to $40.10 when applying the price/earnings multiples and $22.96 to $39.59 when applying multiples of tangible book value.

        In connection with its analyses, Sandler O'Neill considered and discussed with the Citizens Board how the present value analyses would be affected by changes in the underlying assumptions, including variations with respect to net income. Sandler O'Neill noted that the discounted dividend stream and terminal value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

        Pro Forma Merger Analysis.    Sandler O'Neill analyzed certain potential pro forma effects of the merger, assuming the following: (1) the merger closes in the second quarter of 2005, (2) 50% of the Citizens shares are exchanged for Main Street common stock at an exchange ratio of 1.1051 and the other 50% of Citizens' shares are exchanged for $35.00 per share in cash, (3) earnings per share projections for Citizens are consistent with per share estimates for 2004 and 2005 published by I/B/E/S and reviewed with Citizens' management, and long-term earnings per share growth estimates for periods thereafter are consistent with management estimates, (4) earnings per share projections for Main Street are consistent with per share estimates for 2004 and 2005 published by I/B/E/S and reviewed with Main Street management, (5) purchase accounting adjustments, charges and transaction costs associated with the merger and cost savings determined by the senior managements of Citizens and Main Street, and (6) Citizens options are cashed out.The analyses indicated that for the year ending December 31, 2005, the merger would be accretive to Main Street's projected earnings per share and cash earnings per share and dilutive to Main Street's tangible book value per share. The actual results achieved by the combined company may vary from projected results and the variations may be material.

        Citizens has agreed to pay Sandler O'Neill a transaction fee in connection with the merger of approximately $[            ] (based on the closing price of Main Street's common stock as of [            ], 2004), of which $50,000 has been paid and the balance of which is contingent, and payable, upon

47



closing of the merger. The amount of the transaction fee that will actually be paid to Sandler O'Neill will be determined at closing based on 1% of the aggregate transaction value. Sandler O'Neill has also received a fee of $100,000 for rendering its opinion, which will be credited against that portion of the transaction fee due upon closing of the merger. Citizens has also agreed to reimburse certain of Sandler O'Neill's reasonable out-of-pocket expenses incurred in connection with its engagement and to indemnify Sandler O'Neill and its affiliates and their respective partners, directors, officers, employees, agents, and controlling persons against certain expenses and liabilities, including liabilities under securities laws.

        In the ordinary course of our business as a broker-dealer, Sandler O'Neill may purchase securities from and sell securities to Citizens and Main Street and their affiliates. Sandler O'Neill may also actively trade the debt and/or equity securities of Citizens or Main Street or their affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

Representations and Warranties

        In the merger agreement, Citizens and Main Street each made numerous representations and warranties to each other relating to, among other things, the following:

        In addition, Main Street also made a representation and warranty to Citizens relating to its ability to fund the transaction.

        The foregoing is an outline of the types of representations and warranties made by Main Street and Citizens contained in the merger agreement, a copy of which is included at Appendix A. You should carefully review the entire agreement and in particular Articles 4 and 5, containing the detailed representations and warranties of the parties.

Conduct of Business Pending the Merger and Certain Covenants

        Under the merger agreement, Citizens has agreed to certain restrictions on its activities until the merger is completed or the merger agreement is terminated. In general, Citizens and Citizens Savings Bank are required to conduct their operations in the ordinary course of business. The following is a summary of the more significant restrictions and obligations imposed upon Citizens and Citizens Savings Bank. Subject to the exceptions set forth in the merger agreement, Citizens must:

        Citizens has also agreed that it will not encourage any third-party proposals to acquire Citizens and will not participate in negotiations regarding a proposal to acquire Citizens. However, Citizens may provide information and negotiate with a third party if Citizens' board of directors determines that failure to do so would be inconsistent with its fiduciary duties. Citizens is required under the merger agreement to provide Main Street notice of any proposal it receives to acquire Citizens.

        Citizens has also agreed to provide Main Street with certain documents before the closing date, including:

        Main Street has agreed to file all applications and notices to obtain the necessary regulatory approvals for the transactions contemplated by the merger agreement.

        Citizens is only required to complete the merger if the following conditions are satisfied:

51


        Neither party can be certain as to when or if all of the conditions to the merger can or will be satisfied or waived by the party permitted to do so. If the merger is not completed by September 7, 2005, either of our boards of directors may terminate the merger agreement and abandon the merger; provided, however, that the party responsible for a condition not being met prior to September 7, 2005, may not terminate the merger agreement if the merger is not completed by September 7, 2005. See "—Waiver, Amendment and Termination."

        The foregoing is an outline of the types of conditions precedent to the obligations of Main Street and Citizens contained in the merger agreement, a copy of which is included at Appendix A. You should carefully review the entire agreement and in particular Articles 9 and 10, containing the detailed conditions to each party's obligation to close.

Termination and Termination Fees

        Ability to Terminate the Merger Agreement.    At any time before the merger becomes effective, the boards of directors of Citizens and Main Street may mutually agree to terminate the merger agreement. In addition, the merger agreement may be terminated as follows:

        In addition, Citizens may terminate the merger agreement if both:


However, Citizens cannot terminate the merger agreement on the basis of Main Street's stock price if Main Street elects to increase the value of the cash consideration, the stock consideration or a combination of both in such a way that the per share value of the merger consideration at closing will equal at least $29.75.

        Effect of Termination.    If the merger is terminated, the merger agreement will become void and have no effect, except that certain provisions of the merger agreement, including those relating to the obligation to pay expenses and maintain the confidentiality of certain information obtained in connection with the merger and the merger agreement, will survive.

        Termination Fees.    If either:

52



then, in either case, as long as Main Street is in material compliance with its material obligations under the merger agreement, Citizens is required to pay Main Street a termination fee of $1,000,000.

        In addition to the $1,000,000 termination fee described above, if the merger agreement is terminated on one of the bases described above, and within 12 months after this termination Citizens enters into a contract with any party other than Main Street providing for the acquisition of control of Citizens or Citizens Savings Bank, then Citizens is required to pay Main Street an additional fee of $1,300,000.

        Alternatively, if Main Street terminates the merger agreement because either:

then, in either case, provided that the breach has or would reasonably be expected to have a material adverse effect on either Main Street or Citizens, then Citizens is required to pay Main Street a termination fee of $2,300,000.

        If Citizens terminates the merger agreement because of a breach of Main Street's representations and warranties that (a) was not in existence on the date of the merger agreement, (b) was not a result of a failure by Citizens to comply with its material obligations under the merger agreement and (c) has or would reasonably be expected to have a material adverse effect on either Main Street or Citizens, then, as long as Citizens is in material compliance with its material obligations under the merger agreement, Main Street is required to pay Citizens a termination fee of $1,000,000.

        Alternatively, if Citizens terminates the merger agreement because either:

then, in either case, provided that the breach has or would reasonably be expected to have a material adverse effect on either Main Street or Citizens, then Main Street is required to pay Citizens a termination fee of $2,300,000.

53



        The foregoing is an outline of the termination provisions contained in the merger agreement, a copy of which is included at Appendix A. You should carefully review the entire agreement and in particular Article 11, containing the detailed termination provisions.

Waiver and Amendment

        To the extent permitted by law, our boards of directors may agree in writing to amend the merger agreement, whether before or after Citizens' stockholders have approved the merger agreement. However, no amendment agreed to after the merger agreement has been approved by Citizens' stockholders may materially and adversely affect the rights of Citizens' stockholders. In addition, before or at the time the merger becomes effective, either Main Street or Citizens, or both, may waive any default in the performance of any term of the merger agreement by the other or may waive or extend the time for the compliance or fulfillment by the other of any of its obligations under the merger agreement. Either of Main Street or Citizens may also waive any of the conditions precedent to their respective obligations under the merger agreement, unless a violation of any law or governmental regulation would result. To be effective, a waiver must be in writing and signed by one of Main Street's or Citizens' duly authorized officers.

Regulatory Approvals

        It is a condition to the completion of the merger that we receive all necessary regulatory approvals of the merger. Neither Main Street nor Citizens is aware of any material governmental approvals or actions that are required to complete the merger, except as described below. If any other approval or action is required, we will also seek this approval or action.

        Federal Reserve.    The merger is subject to the prior approval of the Board of Governors of the Federal Reserve System, or the Federal Reserve, under Section 3 of the Bank Holding Company Act and Sections 225.11 and 225.15 of Regulation Y of the Federal Reserve. In evaluating the merger, the Federal Reserve is required to consider, among other factors, the financial and managerial resources and future prospects of the institutions and the convenience and needs of the communities to be served. These provisions prohibit the Federal Reserve from approving the merger if:

        The merger may not be completed until 30 days following the date of the Federal Reserve approval, although the U.S. Department of Justice may reduce that period to 15 days. During this period, the U.S. Department of Justice is given the opportunity to challenge the transaction on antitrust grounds. The commencement of any antitrust action would stay the effectiveness of the approval of the agencies, unless a court of competent jurisdiction specifically ordered otherwise.

        Illinois Department of Financial and Professional Regulation.    The change of control of Citizens Savings Bank is subject to the prior approval of the DFPR under Section 8015 of the Illinois Savings Bank Act and Section 1075.1700 of the administrative rules for the Illinois Savings Bank Act. These provisions prohibit the DFPR from approving a change of control of an Illinois savings bank if:

54



        Office of Thrift Supervision.    Because Citizens has elected to be treated as a savings and loan holding company under Section 10(l) of the Home Owners' Loan Act, Main Street must notify the Office of Thrift Supervision that immediately after the merger is completed, Citizens Acquisition LLC, the surviving entity in the merger with Citizens, will be dissolved.

Management and Operations After the Merger

        Immediately following the merger of Citizens with Citizens Acquisition LLC, Citizens Acquisition LLC will dissolve, leaving Main Street as the direct holding company of Citizens Savings Bank. The directors and officers of Main Street will remain the same as they were prior to the merger. Information concerning the management of Main Street is included in the documents incorporated by reference in this proxy statement-prospectus. See "Where You Can Find More Information." For additional information regarding the interests of certain persons in the merger, see "—Interests of Certain Persons in the Merger."

Interests of Certain Persons in the Merger

        General.    Some members of Citizens' management and board of directors may be deemed to have interests in the merger that are in addition to their interests as stockholders generally. The boards of directors of each of Main Street and Citizens were aware of these interests and considered them, together with the other matters described in this proxy statement-prospectus, in adopting the merger agreement and approving the merger.

        Agreements with C. William Landefeld.    Main Street has entered into an employment agreement with C. William Landefeld, which will become effective upon completion of the merger. This employment agreement provides for Mr. Landefeld's employment following the merger as an Executive Vice President of Main Street. The agreement is for a two-year term and provides for an annual base salary of $150,000. The agreement also provides for Mr. Landefeld's participation in all plans or benefits that Main Street makes available to all of its employees.

        Either Main Street or Mr. Landefeld may terminate the employment agreement, at any time, upon 90 days' prior written notice. Main Street may also terminate the employment agreement for cause, as defined in the agreement, on 30 days' prior written notice. If Main Street terminates Mr. Landefeld's employment without cause, he will be entitled to receive a payment equal to the total amount of compensation that he would have received if he had remained employed for the full term of the

55



agreement, calculated as the sum of his base salary plus the value of any contributions that would have been made to Mr. Landefeld or for his benefit under all applicable retirement and benefit plans had he remained employed through the last day of the term. In this event, he will also be entitled to continued health coverage for the full term of his agreement. These severance payments are to be paid to Mr. Landefeld in equal monthly installments.

        Main Street will have no continuing obligation to Mr. Landefeld if he voluntarily terminates his employment or if Main Street terminates him for cause, except in either case for salary and benefits earned through the date of termination.

        Mr. Landefeld's employment agreement includes a covenant limiting his ability for a period of one year following a termination of his employment to compete with Main Street in an area encompassing a 50-mile radius from each banking or other branch office location of Main Street and its subsidiary banks.

        Main Street has also agreed that Mr. Landefeld, in connection with the change of control resulting from the merger, will be entitled to receive a payment of $781,669.20, to be paid in 36 monthly installments of $21,713.03 each following the effective time, in satisfaction of all obligations that may be owed to him under his existing employment agreement with Citizens. This amount is subject to reduction so that the total amount of payments or benefits provided to Mr. Landefeld under the existing employment agreement or other benefit plans, when added to the sum of $5,000, will not constitute an "excess parachute payment" under the Internal Revenue Code.

        Mr. Landefeld will also be entitled to receive, at or prior to the effective time of the merger, (a) a distribution of 15,145 shares of Citizens common stock in respect of the Citizens Supplemental Executive Retirement Plan, plus an additional amount, if any, attributable to the Supplemental Executive Retirement Plan benefit he is entitled to for the 2004 plan year, (b) payment of up to $50,000 under the Citizens 2004 Incentive Bonus Plan and (c) an annuity contract (or cash in lieu thereof) to pay benefits to Mr. Landefeld under the Citizens Advisory Directors Retirement Plan, provided that the aggregate cost to Citizens for purchasing the annuity contracts (or cash in lieu thereof) for Mr. Landefeld and Directors Borngasser and Thompson shall not exceed $510,000.

        Agreements with Dallas Smiley.    Main Street has entered into an employment agreement with Dallas Smiley, which will become effective upon completion of the merger. This employment agreement provides for Mr. Smiley's employment following the merger as a Senior Vice President of Main Street. The agreement is for a term ending on December 31, 2005, and provides for an annual base salary of $100,000. The agreement also provides for Mr. Smiley's participation in all plans or benefits that Main Street makes available to all of its employees.

        Either Main Street or Mr. Smiley may terminate the employment agreement, at any time, upon 90 days' prior written notice. Main Street may also terminate the employment agreement for cause, as defined in the agreement, on 30 days' prior written notice. If Main Street terminates Mr. Smiley's employment without cause, he will be entitled to receive a payment equal to the total amount of compensation that he would have received if he had remained employed for the full term of the agreement, calculated as the sum of his base salary plus the value of any contributions that would have been made to Mr. Smiley or for his benefit under all applicable retirement and benefit plans had he remained employed through the last day of the term. In this event, he will also be entitled to continued health coverage for the full term of his agreement. These severance payments are to be paid to Mr. Smiley in equal monthly installments.

        Main Street will have no continuing obligation to Mr. Smiley if he voluntarily terminates his employment or if Main Street terminates him for cause, except in either case for salary and benefits earned through the date of termination.

56



        Mr. Smiley's employment agreement includes a covenant limiting his ability for a period of one year following a termination of his employment to compete with Main Street in an area encompassing a 50-mile radius from each banking or other branch office location of Main Street and its subsidiary banks.

        Main Street has also agreed that Mr. Smiley, in connection with the change of control resulting from the merger, will be entitled to receive a payment of $631,964.01, to be paid in a single lump sum at closing, in satisfaction of all obligations that may be owed to him under his existing employment agreements with Citizens and Citizens Bank. This amount is subject to reduction so that the total amount of payments or benefits provided to Mr. Smiley under the existing employment agreement or other benefit plans, when added to the sum of $5,000, will not constitute an "excess parachute payment" under the Internal Revenue Code.

        Mr. Smiley will also be entitled to receive, at or prior to the effective time of the merger, (a) a distribution of 1,701 shares of Citizens common stock in respect of the Citizens Supplemental Executive Retirement Plan, plus an additional amount, if any, attributable to the Supplemental Executive Retirement Plan benefit he is entitled to for the 2004 plan year, and (b) payment of up to $20,000 under the Citizens 2004 Incentive Bonus Plan.

        Agreements with Directors Borngasser and Thompson.    Directors Carl S. Borngasser and Dr. Lowell M. Thompson will each also be entitled to receive, at or prior to the effective time, an annuity contract (or cash in lieu thereof) to pay benefits to Messrs. Borngasser and Thompson under the Citizens Advisory Directors Retirement Plan, provided that the aggregate cost to Citizens for purchasing the annuity contracts (or cash in lieu thereof), along with an annuity contract (or cash) for Mr. Landefeld, shall not exceed $510,000.

        Indemnification for Directors and Officers; Insurance.    Main Street has agreed to honor for at least three years from the effective date of the merger all of Citizens' obligations with respect to indemnification currently provided by Citizens in its certificate of incorporation or bylaws in favor of the current and former officers and directors with respect to matters occurring prior to the effective time. In addition, Main Street has agreed to maintain for a period of two years extended insurance coverage of acts or omissions occurring at or prior to the effective time with respect to those persons who are currently covered by Citizens' director and officer liability insurance policies.

        Appointment of Citizens' Nominees.    The merger agreement provides that, immediately after the effective time of the merger, Main Street will expand the board of its subsidiary bank by two members, and that board will then appoint two individuals nominated by Citizens. The Citizens' appointees must be acceptable to Main Street, in its sole discretion.

Additional Agreements

        Voting Agreement.    Each of the directors of Citizens has entered into a voting agreement with Main Street. Under this agreement, these shareholders have agreed to vote their respective shares of Citizens common stock:

57


        Furthermore, and without Main Street's prior approval, each of these shareholders has also agreed not to solicit, initiate or encourage any inquiries or proposals for a merger or other business combination involving Citizens. The shares subject to the voting agreement represent approximately 14.82% of the outstanding shares of Citizens common stock on the record date. The voting agreement will terminate upon the earlier of the consummation of the merger or termination of the merger agreement in accordance with its terms.

        Employee Benefits Agreement.    In an agreement between Citizens and Main Street that was entered into concurrently with the merger agreement, Citizens has agreed to terminate prior to closing its employee benefit plans, and to take such actions as are necessary to properly distribute to the plan participants assets it holds under the plans. On its part, Main Street has agreed that the former employees of Citizens or its subsidiary will become participants in the employee benefit plans of Main Street or its subsidiaries.

Accounting Treatment

        The merger will be accounted for using the purchase method of accounting under generally accepted accounting principles as applied in the United States. Under this method of accounting, Main Street will record the assets acquired and liabilities assumed of Citizens at their fair market values. Any difference between the purchase price and the fair market value of the net tangible and identifiable intangible assets and liabilities is recorded as goodwill, which, in accordance with Statement of Financial Accounting Standard No. 142, will not be amortized for financial accounting purposes, but will be evaluated annually for impairment.

Expenses

        Each of Main Street and Citizens will pay its own expenses in connection with the merger, including filing, registration and application fees, printing fees and fees and expenses of its own financial or other consultants, accountants and counsel.

        Main Street common stock to be issued to Citizens stockholders in the merger will be registered under the Securities Act. All shares of Main Street common stock received by Citizens stockholders in the merger will be freely transferable after the merger by persons who are not considered to be "affiliates" of either Main Street or Citizens. These "affiliates" would generally include any persons or entities who control, are controlled by or are under common control with either Citizens or Main Street at the time of the special meeting (generally, executive officers, directors and 10% or greater stockholders).

        Rule 145 promulgated under the Securities Act restricts the sale of Main Street common stock received in the merger by affiliates of Citizens and certain of their family members and related entities. Under the rule, until the first anniversary of the effective date of the merger, affiliates of Citizens may publicly resell the Main Street common stock they receive in the merger, but only within certain limitations as to the amount of Main Street common stock they can sell in any three-month period and as to the manner of sale. After this first anniversary, affiliates of Citizens who are not affiliates of Main Street may resell their shares without restriction. Main Street must continue to satisfy its reporting requirements under the Securities Exchange Act of 1934, as amended, for affiliates to continue to be able to resell under Rule 145 the shares of Main Street common stock they received in the merger. Affiliates would also be permitted to resell Main Street common stock received in the merger pursuant to an effective registration statement under the Securities Act or an available exemption from the registration requirements. This proxy statement-prospectus does not cover any resales of Main Street common stock received by persons who may be deemed to be affiliates of Citizens.

EFFECT OF THE MERGER ON RIGHTS OF STOCKHOLDERS

General

        Citizens is a Delaware corporation governed by Delaware law and Citizens' certificate of incorporation and bylaws. Main Street is an Illinois corporation governed by Illinois law and Main Street's articles of incorporation and bylaws.

        In the merger, many stockholders of Citizens will receive shares of Main Street common stock which will include all rights attaching to shares of Main Street common stock. There are significant differences between the rights of Citizens' stockholders and the rights of Main Street's stockholders. The following is a summary of the principal differences between the rights.

        The following summary is not intended to be complete and is qualified in its entirety by reference to the Illinois Business Corporation Act and the Delaware General Corporation Law, as well as Main Street's articles of incorporation and bylaws and Citizens' certificate of incorporation and bylaws.

Anti-Takeover Provisions Generally

        Main Street's articles of incorporation and bylaws contain provisions designed to assist Main Street's board of directors in playing a role in any attempt by a group or person to acquire control of Main Street. These provisions are intended to enable Main Street's board of directors to protect the interests of Main Street and its stockholders under the circumstances. Aided by these provisions, Main Street may determine that a sale of control is in the best interests of Main Street's stockholders or will enhance the board's ability to maximize the value to be received by the stockholders upon a sale of control of Main Street.

        Although Main Street's management believes that these provisions are beneficial to Main Street's stockholders, they may also tend to discourage some takeover bids. As a result, Main Street's stockholders may be deprived of opportunities to sell some or all of their shares at prices that represent a premium over prevailing market prices. On the other hand, defeating undesirable acquisition offers can be a very expensive and time-consuming process. To the extent that these provisions discourage undesirable proposals, Main Street may be able to avoid those expenditures of time and money.

        These provisions may also discourage open market purchases of Main Street common stock by a company that may desire to acquire Main Street. Those purchases may increase the market price of Main Street common stock temporarily and enable stockholders to sell their shares at a price higher than they might otherwise obtain. In addition, these provisions may decrease the market price of Main Street common stock by making the stock less attractive to persons who invest in securities in anticipation of price increases from potential acquisition attempts. The provisions may also make it more difficult and time consuming for a potential acquiror to obtain control of Main Street through replacing the board of directors and management. Furthermore, the provisions may make it more difficult for Main Street's stockholders to replace the board of directors or management, even if a majority of the stockholders believe that replacing the board of directors or management is in the best interests of Main Street. Because of these factors, these provisions may tend to perpetuate the incumbent board of directors and management.

Authorized Capital Stock

        Main Street.    Main Street is authorized to issue 15,000,000 shares of common stock, $0.01 par value per share, and 2,000,000 shares of preferred stock, no par value per share. As of September 30, 2004, 11,219,319 shares of Main Street common stock were issued, including 1,770,996 shares held by Main Street as treasury shares. No shares of Main Street preferred stock are issued and outstanding. The Main Street board of directors may authorize the issuance of additional shares of common stock

59


without further action by its stockholders, unless applicable laws or regulations or a stock exchange on which Main Street's capital stock is listed requires stockholder action.

        Main Street may issue, without a stockholder vote, shares of its preferred stock, in one or more classes or series, with voting, conversion, dividend and liquidation rights as it specifies in its articles. The Main Street board of directors may determine, among other things, the distinctive designation and number of shares comprising a series of preferred stock, the dividend rate or rates on the shares of such series and the relation of such dividends to the dividends payable on other classes of stock, whether the shares of such series will be convertible into or exchangeable for shares of any other class or series of Main Street capital stock, the voting powers if any of such series, and any other preferences, privileges and powers of such series.

        Upon the voluntary or involuntary liquidation, dissolution, distribution of assets or winding up of Main Street, holders of its preferred stock, if any, will have priority over holders of common stock.

        The authority to issue additional shares of common stock or preferred stock provides Main Street with the flexibility necessary to meet its future needs without the delay resulting from the need to obtain stockholder approval for the issuance. The authorized but unissued shares of common stock and preferred stock may be issued from time to time for any corporate purpose, including stock splits, stock dividends, employee benefit and compensation plans, acquisitions and public or private sales for cash as a means of raising capital. The shares could be used to dilute the stock ownership of persons seeking to obtain control of Main Street. The sale of a substantial number of shares of voting stock to persons who have an understanding with Main Street concerning the voting of such shares or the distribution or declaration of a dividend of shares of voting stock (or the right to receive voting stock) to its stockholders may have the effect of discouraging or increasing the cost of unsolicited attempts to acquire control of Main Street.

        Citizens.    Citizens is authorized to issue 8,000,000 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. As of the record date, 2,817,500 shares of Citizens common stock were issued, including 1,250,042 shares that are held by Citizens as treasury shares. No shares of Citizens preferred stock are issued and outstanding.

        Citizens' board of directors has substantially the same powers with respect to the issuance of common stock and preferred stock as does Main Street's board of directors described above.

Voting Rights

        Main Street.    Generally, holders of Main Street common stock are entitled to one vote per share on all matters submitted to a vote of stockholders.

        As stated above, Main Street's board of directors is authorized to issue up to 2,000,000 shares of preferred stock, and may designate various characteristics and rights of Main Street preferred stock, including voting and conversion rights. Main Street's board of directors may also authorize the conversion of shares of other classes of Main Street preferred stock into any number of shares of Main Street common stock and thus dilute the outstanding shares of Main Street common stock. Subject to the board's fiduciary duties, Main Street could issue convertible preferred stock with the purpose or effect of deterring or preventing a takeover of Main Street.

        Main Street's articles of incorporation do not provide for cumulative voting rights in the election of directors.

        Citizens.    Generally, holders of Citizens common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. However, under Citizens' certificate of incorporation, any stockholder that beneficially owns more than 10% of Citizens common stock can only vote the shares

60



of stock that exceed the 10% limit in accordance with a formula contained in the certificate of incorporation.

        As stated above, Citizens' board of directors is authorized to issue up to 1,000,000 shares of preferred stock and may designate various characteristics and rights of Citizens preferred stock including issuance of the shares of preferred stock in series by filing a certificate pursuant to the applicable law of the state of Delaware. Citizens' board of directors may also increase or decrease the number of authorized shares of Citizens preferred stock by the affirmative vote of the holders of a majority of the Citizens common stock, without the vote of the holder of the preferred stock, or any series of preferred stock, unless such a vote is required by the terms of any preferred stock designation.

Classification of Board of Directors

        Main Street.    Main Street's articles of incorporation do not provide for the division of its board of directors into classes.

        Citizens.    Citizens' certificate of incorporation provides for the division of its board of directors into three classes of approximately equal size. Citizens' directors are elected for three-year terms, and the terms of office of approximately one-third of the members of the classified board of directors expire each year. This board classification may make it more difficult for a stockholder to acquire immediate control of Citizens and remove management by means of a proxy contest. Because the terms of approximately one-third of the incumbent directors expire each year, at least two annual elections would be necessary for stockholders to replace a majority of Citizens' directors, while a majority of directors of a non-classified board, such as Main Street's, could be replaced in one annual meeting.

Size of the Board of Directors; Qualifications; Vacancies; Removal

        Main Street.    Main Street's articles of incorporation provide that the size of the board of directors must consist of at least 9, but no more than 17, directors, as fixed by a majority of Main Street's directors. The articles of incorporation and bylaws also provide that any vacancy occurring on the board of directors may be filled for the remainder of the unexpired term by a majority vote of the directors then in office.

        Under the Illinois Business Corporation Act, a director may be removed, with or without cause, by the affirmative vote of a majority of stockholders.

        Citizens.    Citizens' certificate of incorporation and bylaws provide that the size of the board of directors may be changed from time to time pursuant to a resolution adopted by a majority of the board or directors. The bylaws also provide that any vacancy occurring on the board of directors may be filled for the remainder of the unexpired term by a majority vote of the directors then in office.

        Under Citizens' bylaws, to be eligible to serve as a director, an individual must meet the following qualifications:

61


        Under the Delaware General Corporation Law, members of a classified board of directors may only be removed for cause, unless the certificate of incorporation provides otherwise. Citizens' certificate of incorporation provides that a director may only be removed for cause and only by the vote of 80% of holders of the shares eligible to vote in the election of directors. Citizens' certificate of incorporation does not contain a definition of "cause."

Stockholder Nominations and Proposals

        Main Street.    Main Street's bylaws provide that the only business that may be conducted at an annual meeting is the business brought before the meeting in Main Street's notice of the meeting, by or at the direction of the board of directors or by any stockholder who complies with the notice provisions set forth in Main Street's bylaws. For business to be brought by a stockholder at an annual meeting, the stockholder must have given timely notice, in writing, to the secretary of Main Street. To be timely, a stockholder's notice must be received at the principal executive offices of Main Street no less than 60 and no more than 90 days prior to the anniversary of the previous year's annual meeting.

        A stockholder's notice to the secretary must set forth, as to each matter the stockholder proposes to bring before the meeting:

        The proposal also must include the stockholder's name and address, the name and address of any beneficial owner on whose behalf the proposal is made and the class and number of shares of capital stock owned by the stockholder and the beneficial owner, if any.

        Main Street's bylaws provide that nominations for election to Main Street's board of directors must be made only by the board of directors or by any stockholder entitled to vote who complies with the notice procedures set forth in the bylaws. Those notice provisions are comparable to those set forth above for new business to be brought before a stockholders' meeting, except that the stockholder may also make a nomination at a special meeting so long as the notice is delivered no less than 60 and no more than 90 days prior to the special meeting. The notice must set forth as to each person the stockholder wishes to nominate the nominee's name, age, address and occupation or employment, as well as the number of shares owned by the nominee.

        Citizens.    Citizens' bylaws contain a comparable stockholder proposal provision as that contained in Main Street's bylaws. The stockholder nomination provision in Citizens' bylaws are also comparable to those contained in Main Street's bylaws, except that there is no provision relating to nominations to be made at special meetings.

62



Special Meetings of Stockholders

        Main Street.    Main Street's bylaws provide that a special meeting of stockholders may be called at any time for any purpose permitted by law and the articles of incorporation by the president, a majority of the board of directors or the holders of at least one-fifth of the shares entitled to vote on the matter. The only business that may be conducted at a special meeting is that set forth in the notice of the special meeting.

        Citizens.    Citizens' certificate and bylaws provide that special meetings may be called only by the board of directors pursuant to a resolution adopted by a majority of the members of the entire board of directors. The only business that may be conducted at a special meeting is business brought by or at the direction of Citizens' board of directors.

Action by Written Consent

        Main Street.    Under Illinois law, unless a corporation's articles of incorporation provide otherwise, any action required to be taken at an annual or special meeting of stockholders may instead be adopted by a written consent signed by the holders of outstanding shares having at least the minimum number of votes that would be required to approve such action at a meeting. Main Street's articles of incorporation and bylaws do not limit this ability to take action by written consent.

        Citizens.    Citizens' certificate of incorporation prohibits its stockholders from taking action by written consent.

Dividends

        Main Street.    Main Street's ability to pay dividends is governed by Illinois corporate law. Under Illinois corporate law, dividends may be paid so long as after giving effect to their payment the corporation would not be insolvent and the corporation's net assets would not be less than zero or less than the maximum amount necessary at the time of payment of the dividends to satisfy any preferential rights upon dissolution to stockholders whose preferential rights are superior to those receiving the dividends. Subject to Illinois law, Main Street's articles of incorporation state that the board of directors may declare and pay dividends from time to time.

        Most of the revenues of Main Street available for the payment of dividends derive from amounts paid to it by its banking subsidiaries. There are various statutory limitations that limit the ability of the subsidiaries to pay dividends to Main Street. Main Street's state-charted bank subsidiary is subject to the laws and regulations of the DFPR and to the regulations of the FDIC. If a bank's primary federal banking regulator determines that the bank is engaged or is about to engage in an unsafe or unsound banking practice, the regulator may require, after notice and hearing, that the bank cease and desist from such practice. Depending on the financial condition of the bank, an unsafe or unsound practice could include the payment of dividends. In particular, the federal banking agencies have indicated that paying dividends that deplete a bank's capital base to an inadequate level would be an unsafe and unsound banking practice. Under the Federal Deposit Insurance Corporation Improvement Act of 1991, a bank may not pay a dividend if the payment would cause it to become undercapitalized or if it is already undercapitalized. The federal agencies have also issued policy statements that provide that bank holding companies and insured banks should generally pay dividends only out of current operating earnings.

        Citizens.    Citizens' ability to pay dividends on its common stock is governed by Delaware corporate law. Under Delaware corporate law, unless there are restrictions in the corporation's certificate of incorporation, dividends may be declared from the corporation's surplus, or, if there is no surplus, from its net profits for the fiscal year in which the dividend is declared and the preceding years. Dividends may not be declared, however, if the corporation's capital is less than the amount of

63



all capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Subject to Delaware law, Citizens' bylaws state that the board of directors may declare dividends from time to time.

        Like Main Street, most of the revenues of Citizens available for the payment of dividends derive from amounts paid to it by its banking subsidiary. There are various statutory limitations that limit the ability of Citizens Savings Bank to pay dividends to Citizens, which are discussed above for Main Street.

Special Voting Requirements; Business Combinations

        Main Street.    Subject to contrary provisions in a corporation's articles of incorporation, the Illinois Business Corporation Act provides that a corporation may engage in any merger, consolidation or a sale or lease of all or substantially all of its assets if such transaction is approved by the corporation's board of directors and ratified by the vote of holders of two-thirds or more of the corporation's issued and outstanding shares of voting stock. Main Street's articles provide that holders of only a majority of Main Street common stock must approve this type of transaction.

        Citizens.    Subject to the special voting requirements discussed below, the Delaware General Corporation Law provides that a majority of the outstanding stock of a corporation is required to approve a merger or consolidation. Under Citizens' certificate of incorporation, holders of at least 80% of the voting stock must approve specified transactions with a 10% or more stockholder, generally referred to as an "interested stockholder." The transactions that are subject to these special approval requirements are:

        However, Citizens' certificate of incorporation states that approval of only a majority of the voting stock is needed if either:

        The amendment of these interested stockholder provisions of Citizens' certificate of incorporation requires the affirmative vote of holders of not less than 80% of Citizens' outstanding voting stock.

64



        In addition, Section 203(d) of the Delaware General Corporation Law prohibits Citizens from engaging in a business combination, as defined by the Delaware General Corporation Law, with an interested stockholder, defined as a person who owns, directly or indirectly, 15% or more of Citizens' outstanding voting stock, for a three year period from the date the person became an interested stockholder, referred to as the acquisition date, unless:

Amendment of Charter Documents

        Main Street.    Main Street may amend its articles of incorporation in any manner permitted by Illinois law. The Illinois Business Corporation Act provides that a corporation's articles of incorporation may be amended by holders of two-thirds or more of the shares entitled to be voted on an amendment, unless the corporation's articles of incorporations provide otherwise. Main Street's articles provide that they can be amended by holders of a majority of the shares of Main Street common stock entitled to be voted on an amendment.

        Main Street's board of directors may adopt, amend or repeal Main Street's bylaws by a majority vote of the entire board of directors. The bylaws may also be amended or repealed by action of Main Street's stockholders.

        Citizens.    The Delaware General Corporation Law provides that amendments to a corporation's certificate of incorporation must be approved by holders of a majority of the issued and outstanding shares of a corporation's voting stock. However, Citizens' certificate of incorporation provides that specified amendments to the certificate of incorporation must be approved by 80% of the then outstanding shares of Citizens common stock entitled to vote generally for directors, voting as a single class. These specified provisions relate to the following:

65


        Citizens' bylaws provide that they may be amended at any meeting of its board of directors, provided that notice of the proposed change is given at least two days before the meeting is held. Stockholders may also amend the bylaws at any meeting of the stockholders, provided that notice of the proposed amendment is given in the notice of the meeting and the amendment is approved by the affirmative vote of 80% of the voting power of the outstanding common stock eligible to vote.

Limitations on Director Liability

        Main Street.    Main Street's articles of incorporation provide that a director will not be personally liable, to the fullest extent permitted by the Illinois Business Corporation Act, to Main Street or its stockholders for monetary damages resulting from the director's breach of his or her duty of care. The Illinois Business Corporation Act permits a corporation to limit a director's personal liability to this extent, except:

        Citizens.    Citizens' certificate of incorporation contains substantially the same limitation on the personal liability of its directors as Main Street's articles of incorporation.

Indemnification

        Main Street.    Under Illinois law, directors, officers, employees and agents of a corporation may be indemnified against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement under certain circumstances. In certain types of actions, suits or proceedings, whether they are civil, criminal, administrative or investigative (other than an action by, or in the right of the corporation, i.e., a "derivative action"), such individuals may be indemnified against individual liability if he or she acted in good faith and in a manner he or she reasonable believed to be in, or not opposed to, the best interest of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A similar standard applies in the case of derivative actions, except that indemnification only extends to expenses (including attorneys' fees) resulting from the defense or settlement of such actions. In the case of derivative actions, Illinois law requires court approval before there can be any indemnification when the person seeking indemnification has been found liable to the corporation. To the extent that a person otherwise eligible to be indemnified is successful on the merits or otherwise of any claim or defense, indemnification is required for expenses (including attorneys' fees) actually and reasonably incurred.

        Expenses incurred by a director, officer, employee or agent of a corporation in defending a proceeding may be paid by the corporation in advance of the final disposition of the proceeding upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay the amount of any advance if it is ultimately determined that he or she is not entitled to be indemnified by the corporation as authorized by Illinois law.

        Main Street's articles of incorporation and bylaws provide for the indemnification of its directors and officers and of any person serving at the request of Main Street as a director, officer or partner of another enterprise, to the fullest extent permitted by Illinois law.

        Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers or persons controlling Main Street under the provisions described above, Main Street has been informed that, in the opinion of the Securities and Exchange Commission, such

66



indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

        Citizens.    Citizens is subject to the provisions of Delaware law with respect to indemnification. Delaware and Illinois law are substantially the same in this area and Citizens' certificate of incorporation contains substantially the same provisions governing indemnification as Main Street's articles of incorporation.

Appraisal and Dissenters' Rights

        Main Street.    Under the Illinois Business Corporation Act, a stockholder is entitled in certain events to dissent from a corporate action and obtain the fair value in cash of his or her shares. These events include:

        Main Street's articles of incorporation and bylaws do not provide for any additional dissenters' rights.

        Citizens.    Under Section 262 of the Delaware General Corporation Law, stockholders of a Delaware corporation generally are entitled to demand appraisal in connection with a merger or consolidation and receive payment in cash of the fair value of their stock, as determined by the Delaware Court of Chancery. However, appraisal rights are not granted under Delaware law with respect to any transaction involving the sale, lease or exchange of substantially all of the assets of a corporation. In addition, appraisal rights are not available in certain circumstances with respect to shares of stock that are listed on a national securities exchange. Citizens' certificate of incorporation and bylaws do not provide for any additional appraisal rights. See "Special Meeting—Appraisal Rights" for additional information.

BUSINESS OF CITIZENS

General

        Citizens was incorporated under Delaware law in January 1996 to become the holding company for its bank subsidiary, Citizens Savings Bank. Citizens completed an initial public offering in May 1996 in connection with the conversion of Citizens Savings Bank from the mutual to stock form of ownership. Citizens Savings Bank's principal business consists of the acceptance of retail deposits from the general public in the area surrounding its branch offices and the investment of those deposits, together with funds generated from operations and borrowings, in commercial, agricultural, residential real estate mortgage, commercial real estate, consumer and other loans. Citizens Savings Bank's revenues are derived principally from interest on its mortgage, consumer and commercial loans, loan servicing fees and, to a lesser extent, the interest on its securities. Citizens Savings Bank's primary source of funds are deposits, principal and interest payments on loans and securities, borrowings from the Federal Home Loan Bank of Chicago and, to a lesser extent, proceeds from the sale of loans and securities.

        As of September 30, 2004, Citizens had total consolidated assets of approximately $327.1 million, total consolidated loans of approximately $240.1 million, total consolidated deposits of approximately $231.4 million and total consolidated stockholders' equity of approximately $34.2 million.

All such Citizens Loans are, and at the Closing will be, free and clear of any encumbrance or other charge (except for liens, if any, set forth on Schedule 4.9) and each Citizens Subsidiary has complied, and at the Closing will have complied with all Legal Requirements relating to such Citizens Loans, except where any such failure to comply would not reasonably be expected to have a Material Adverse Effect on Citizens on a consolidated basis.

The MSTI Loans are evidenced by appropriate and sufficient documentation and constitute valid and binding obligations to such MSTI Subsidiary enforceable in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors' rights generally and subject to general principles of equity. All such MSTI Loans are, and at the Closing will be, free and clear of any encumbrance or other charge and each MSTI Subsidiary has complied, and at the Closing will have complied with, all Legal Requirements relating to such MSTI Loans, except where any such failure to comply would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis. The allowance for loan and lease losses of each MSTI Subsidiary is, and will be on the Closing Date, adequate in all material respects to provide for possible or specific losses, net of recoveries relating to loans previously charged off, and contains and will contain an additional amount of unallocated reserves for unanticipated future losses at an adequate level. To the Knowledge of MSTI: (i) none of the MSTI Loans is subject to any material offset or claim of offset; and (ii) the aggregate loan balances in excess of MSTI's consolidated allowance for loan and lease losses are, based on past loan loss experience, collectible in accordance with their terms (except as limited above) and all uncollectible loans have been charged off.

        5.12    Undisclosed Liabilities; Adverse Changes.    Except as set forth in Schedule 5.12 or the MSTI SEC Documents, neither MSTI nor any MSTI Subsidiary has any material liabilities or obligations of any nature (whether absolute, accrued, contingent or otherwise), except for liabilities or obligations reflected or reserved against in the MSTI Financial Statements, and current liabilities incurred in the Ordinary Course of Business since the respective dates thereof. Since the date of the latest MSTI Financial Statement, there has not been any change in the business, operations, properties, prospects, assets or condition of MSTI or any MSTI Subsidiary, and, to MSTI's Knowledge, no event has occurred or circumstance exists, that has had, or would reasonably be expected to have, a Material Adverse Effect on MSTI on a consolidated basis.

        5.13    Taxes.    MSTI and each MSTI Subsidiary has duly filed all material Tax Returns required to be filed by it, and each such Tax Return is complete and accurate in all material respects. MSTI and each MSTI Subsidiary has paid, or made adequate provision for the payment of, all Taxes (whether or not reflected in Tax Returns as filed or to be filed) due and payable by MSTI or any MSTI Subsidiary, or claimed to be due and payable by any Regulatory Authority, and is not delinquent in the payment of any Tax, except such Taxes as are being contested in good faith and as to which adequate reserves have been provided. There is no claim or assessment pending or, to the Knowledge of MSTI, Threatened against MSTI or any MSTI Subsidiary for any Taxes owed by any of them. No audit, examination or investigation related to Taxes paid or payable by MSTI or any MSTI Subsidiary is presently being conducted or, to the Knowledge of MSTI, Threatened by any Regulatory Authority.

        5.14    Compliance with ERISA.    Except as set forth on Schedule 5.14, all employee benefit plans (as defined in Section 3(3) of ERISA) established or maintained by MSTI or any MSTI Subsidiary or to which MSTI or any MSTI Subsidiary contributes, are in compliance with all applicable requirements of ERISA, and are in compliance with all applicable requirements (including qualification and non-discrimination requirements in effect as of the Closing) of the Code for obtaining the tax benefits the Code thereupon permits with respect to such employee benefit plans. No such employee benefit plan has any amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of ERISA) for which MSTI or any MSTI Subsidiary would be liable to any Person under Title IV of ERISA if any such employee benefit plan were terminated as of the Closing. Such employee benefit plans are funded in accordance with Section 412 of the Code (if applicable). There would be no obligations of MSTI or any MSTI Subsidiary under Title IV of ERISA relating to any such employee benefit plan that is a

A-38



multi-employer plan if any such plan were terminated or if MSTI or such MSTI Subsidiary withdrew from any such plan as of the Closing. All contributions and premium payments that are due under any such benefit plans have been made.

        5.15    Compliance With Legal Requirements.    MSTI and each MSTI Subsidiary holds all licenses, certificates, permits, franchises and rights from all appropriate Regulatory Authorities necessary for the conduct of its respective business. Except as set forth in Schedule 5.15 or the MSTI SEC Documents, MSTI and each MSTI Subsidiary is, and at all times since January 1, 2001, has been, in compliance with each Legal Requirement that is or was applicable to it or to the conduct or operation of its respective businesses or the ownership or use of any of its respective assets, except where the failure to comply would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis. No event has occurred or circumstance exists that (with or without notice or lapse of time): (a) may constitute or result in a violation by MSTI or any MSTI Subsidiary of, or a failure on the part of MSTI or any MSTI Subsidiary to comply with, any Legal Requirement; or (b) may give rise to any obligation on the part of MSTI or any MSTI Subsidiary to undertake, or to bear all or any portion of the cost of, any remedial action of any nature in connection with a failure to comply with any Legal Requirement; except, in either case where the failure to comply would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis. Except as set forth on Schedule 5.15 or the MSTI SEC Documents, neither MSTI nor any MSTI Subsidiary has received, at any time since January 1, 2001, any notice or other communication (whether oral or written) from any Regulatory Authority or any other Person, nor does MSTI have any Knowledge, regarding: (x) any actual, alleged, possible or potential violation of, or failure to comply with, any Legal Requirement; or (y) any actual, alleged, possible, or potential obligation on the part of MSTI or any MSTI Subsidiary to undertake, or to bear all or any portion of the cost of, any remedial action of any nature in connection with a failure to comply with any Legal Requirement, except where any such violation, failure or obligation would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis.

        5.18    Material Contracts.    Except as disclosed in Schedule 5.18 or the MSTI SEC Documents, neither MSTI nor any MSTI Subsidiary is a party to, and none of their respective properties or assets are bound by: (a) any "material contract," as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC; or (b) any Contract containing covenants that in any way purport to restrict in any material respect the business activity of MSTI or any MSTI Subsidiary or any Affiliate of any of the foregoing, or limit in any material respect the ability of MSTI or any MSTI Subsidiary or any Affiliate of any of the foregoing to engage in any line of business or to compete with any Person. Copies of any such document, plan or Contract listed and described in Schedule 5.18 are appended to such Schedule.

        5.19    No Defaults.    Except as set forth in Schedule 5.19, to the Knowledge of MSTI, each Contract identified or required to be identified in Schedule 5.18 or in the MSTI SEC Documents is in full force and effect and is valid and enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors' rights generally and subject to general principles of equity. MSTI and each MSTI Subsidiary is, and at all times since January 1, 2001, has been, in full compliance with all applicable terms and requirements of each Contract under which MSTI or any MSTI Subsidiary has or had any obligation or liability or by which MSTI or any MSTI Subsidiary or any of their respective assets owned or used by them is or was bound, except where the failure to be in full compliance would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis. To the Knowledge of MSTI, each other Person that has or had any obligation or liability under any such Contract under which MSTI or any MSTI Subsidiary has or had any rights is, and at all times since January 1, 2001, has been in full compliance with all applicable terms and requirements of such Contract, except where the failure to be in full compliance would not reasonably be expected to have a Material Adverse Effect on MSTI on a consolidated basis. No event has occurred or circumstance exists that (with or without notice or lapse of time) may contravene, conflict with or result in a material violation or breach of, or give MSTI, any MSTI Subsidiary or other Person the right to declare a default or exercise any remedy under, or to accelerate the maturity or performance of, or to cancel, terminate or modify, any Contract. Except in the Ordinary Course of Business with respect to any MSTI Loan, neither MSTI nor any MSTI Subsidiary has given to or received from any other Person, at any time since January 1, 2001, any notice or other communication (whether oral or written) regarding any actual, alleged, possible or potential material violation or breach of, or default under, any Contract, that has not been terminated or satisfied prior to the Agreement Date. Other than in the Ordinary Course of Business in connection with workouts and restructured loans, there are no renegotiations of, attempts to renegotiate, or outstanding rights to renegotiate, any material amounts paid or payable to MSTI or any MSTI Subsidiary under current or completed Contracts with any Person, and no such Person has made written demand for such renegotiation.

        5.20    Compliance with Environmental Laws.    Except as set forth on Schedule 5.20, there are no actions, suits, investigations, liabilities, inquiries, Proceedings or Orders involving MSTI or any MSTI Subsidiary or any of their respective assets that are pending or to the Knowledge of MSTI, Threatened, nor to the Knowledge of MSTI is there any factual basis for any of the foregoing, as a result of any

A-40



asserted failure of MSTI or any MSTI Subsidiary, or any predecessor thereof, to comply with any Environmental Law.

        5.21    Regulatory Filings.    MSTI and each MSTI Subsidiary have filed in a timely manner all required filings with all Regulatory Authorities, including the Federal Reserve, the FDIC, the DFPR, the Secretary of State of the State of Illinois and the SEC, together with any amendment required to be made with respect thereto, including annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and proxy statements. All such filings, including the financial statements, exhibits and schedules thereto, were accurate and complete in all material respects as of the dates of the filings, and no such filing has made any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made, in the light of the circumstances under which they were made, not misleading. Each of such filings, including the financial statements, exhibits and schedules thereto, complied in all material respects with all of the Legal Requirements enforced or promulgated by the Regulatory Authority with which they were filed.

        5.22    Indemnification Claims.    To MSTI's Knowledge, no action or failure to take action by any director, officer, employee or agent of MSTI or any MSTI Subsidiary has occurred that may give rise to a claim or a potential claim by any such Person for indemnification against MSTI or any MSTI Subsidiary under any agreement with, or the corporate indemnification provisions of, MSTI or any MSTI Subsidiary, or under any Legal Requirements.

        5.23    Brokerage Commissions.    None of MSTI or any MSTI Subsidiary or any of their respective Representatives has incurred any obligation or liability, contingent or otherwise, for brokerage or finders' fees or agents' commissions or other similar payment in connection with this Agreement or the Contemplated Transactions, except as disclosed on Schedule 5.23.

        5.24    Approval Delays.    To the Knowledge of MSTI, there is no reason why the granting of any of the regulatory approvals referred to in Section 8.1 would be denied or unduly delayed. Each MSTI Subsidiary that is a "depository institution" as defined in the FDIA has a recent CRA rating of "satisfactory" or better.

        5.25    Disclosure.    Neither any representation nor warranty of MSTI in, nor any schedule to, this Agreement contains any untrue statement of a material fact, or omits to state a material fact necessary to make the statements contained herein or therein, in light of the circumstances under which they were made, not misleading.

APPENDIX B

Fairness Opinion of Sandler O'Neill & Partners, L.P.

November 7, 2004

Board of Directors
Citizens First Financial Corp.
2101 North Veterans Parkway
P.O. Box 1207
Bloomington, IL 61702

Ladies and Gentlemen:

        Citizens First Financial Corp. ("Citizens"), Main Street Trust, Inc. ("MSTI") and Citizens Acquisition LLC ("Acquisition LLC") have entered into an Agreement and Plan of Merger, dated as of November 7, 2004 (the "Agreement"), pursuant to which Citizens will be merged with and into Acquisition LLC, with Acquisition LLC being the surviving entity as a wholly owned subsidiary of Main Street (the "Merger"). Under the terms of the Agreement, upon consummation of the Merger, each share of Citizens common stock, par value $0.01 per share, issued and outstanding immediately prior to the Merger (the "Citizens Shares"), other than certain shares specified in the Agreement, will be converted into the right to receive, at the election of the holder thereof, either (a) 1.1051 shares of MSTI common stock, par value $0.01 per share (the "Stock Consideration"), or (b) $35.00 in cash without interest (the "Cash Consideration"), subject to the election and allocation procedures set forth in the Agreement which provide generally, among other things, that 50% of the Citizens Shares will be converted into the Stock Consideration and 50% of the Citizens Shares will be converted into the Cash Consideration (the Stock Consideration and the Cash Consideration hereinafter collectively referred to as, the "Merger Consideration"). Shares of Citizens common stock (other than certain shares specified in the Agreement) held by stockholders who own fewer than 100 shares of Citizens common stock at the effective time of the Merger will be converted into $35.00 in cash per share. Cash will be paid in lieu of fractional shares in an amount determined by taking the product of the relevant fraction and $31.67. The other terms and conditions of the Merger are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Merger Consideration to the holders of Citizens Shares.

        Sandler O'Neill & Partners, L.P., as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed, among other things: (i) the Agreement; (ii) certain publicly available financial statements and other historical financial information of Citizens that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of MSTI that we deemed relevant; (iv) financial projections for the years ending December 31, 2004 and 2005 reviewed in discussions with senior management of Citizens and earnings per share estimates for Citizens for the years ending December 31, 2004 and 2005 published by I/B/E/S and reviewed by and confirmed with management of Citizens; (v) financial projections for the years ending December 31, 2004 and 2005 reviewed in discussions with senior management of MSTI and earnings per share estimates for MSTI for the years ending December 31, 2004 and 2005 published by I/B/E/S and reviewed by and confirmed with management of Citizens; (vi) the pro forma financial impact of the Merger on MSTI, based on assumptions relating to transaction expenses, purchase accounting adjustments and cost savings determined by the senior managements of Citizens and MSTI; (vii) the publicly reported historical price and trading activity for Citizens' and MSTI's common stock, including a comparison of certain financial and stock market information for Citizens and MSTI with similar publicly available information for certain other companies the securities of which are publicly traded; (viii) the financial terms of certain recent business combinations in the savings institution industry, to the extent publicly

B-1



available; (ix) the current market environment generally and the banking environment in particular; and (x) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of senior management of Citizens the business, financial condition, results of operations and prospects of Citizens and held similar discussions with certain members of senior management of MSTI regarding the business, financial condition, results of operations and prospects of MSTI. In connection with our engagement, we were not asked to, and did not, solicit indications of interest in a potential transaction from third parties.

        In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by Citizens or MSTI or their respective representatives or that was otherwise reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. We have further relied on the assurances of management of Citizens and MSTI that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to undertake and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Citizens or MSTI or any of their subsidiaries, or the collectibility of any such assets, nor have we been furnished with any such evaluations or appraisals. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Citizens or MSTI nor have we reviewed any individual credit files relating to Citizens or MSTI. We have assumed, with your consent, that the respective allowances for loan losses for both Citizens and MSTI are adequate to cover such losses and will be adequate on a combined basis for the combined entity.

        With respect to the financial projections for Citizens and MSTI and all projections of transaction costs, purchase accounting adjustments and expected cost savings prepared by and/or reviewed with the managements of Citizens and MSTI and used by Sandler O'Neill in its analyses, Citizens' and MSTI's management confirmed to us that these projections reflected the best currently available estimates and judgments of the respective managements of the respective future financial performances of Citizens and MSTI and we assumed that such performances would be achieved. We express no opinion as to such financial projections or the assumptions on which they are based. We have also assumed that there has been no material change in Citizens' or MSTI's assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analysis that Citizens and MSTI will remain as going concerns for all periods relevant to our analyses, that all of the representations and warranties contained in the Agreement and all related agreements are true and correct, that each party to the agreements will perform all of the covenants required to be performed by such party under the agreements, that the conditions precedent in the agreements are not waived and that the Merger will be a tax-free reorganization for federal income tax purposes. Finally, with your consent, we have relied upon the advice Citizens has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement.

        Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We are expressing no opinion herein as to what the value of MSTI's common stock will be when issued to Citizens' shareholders pursuant to the Agreement or the prices at which Citizens' or MSTI's common stock may trade at any time.

B-2



        We have acted as Citizens' financial advisor in connection with the Merger and will receive a fee for our services, a substantial portion of which is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion. Citizens has also agreed to indemnify us against certain liabilities arising out of our engagement.

        In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Citizens and MSTI and their affiliates. We may also actively trade the equity or debt securities of Citizens and MSTI or their affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

        Our opinion is directed to the Board of Directors of Citizens in connection with its consideration of the Merger and does not constitute a recommendation to any shareholder of Citizens as to how such shareholder should vote at any meeting of shareholders called to consider and vote upon the Merger or the form of consideration such shareholder should elect in the Merger. Our opinion is directed only to the fairness, from a financial point of view, of the Merger Consideration to holders of Citizens Shares and does not address the underlying business decision of Citizens to engage in the Merger, the relative merits of the Merger as compared to any other alternative business strategies that might exist for Citizens or the effect of any other transaction in which Citizens might engage. Our opinion is not to be quoted or referred to, in whole or in part, in a registration statement, prospectus, proxy statement or in any other document, nor shall this opinion be used for any other purposes, without Sandler O'Neill's prior written consent; provided however, that we hereby consent to the inclusion of this opinion as an appendix to the proxy statement/prospectus of Citizens and Main Street relating to the Merger and to the references to this opinion therein.

        Based upon and subject to the foregoing, it is our opinion, as of the date hereof, that the Merger Consideration to be received by the holders of Citizens Shares is fair to such shareholders from a financial point of view.

  Very truly yours,

 

/s/  
SANDLER O'NEILL & PARTNERS, L.P.

APPENDIX C

Section 262 of the Delaware General Corporation Law

§262. Appraisal rights.

        (a)   Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

        (b)   Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

C-1


        (c)   Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

        (d)   Appraisal rights shall be perfected as follows:

C-2


        (e)   Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

        (f)    Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

        (g)   At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

        (h)   After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the

C-3



Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

        (i)    The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

        (j)    The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

        (k)   From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

        (l)    The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation. (8 Del. C. 1953, §262; 56 Del. Laws, c. 50; 56 Del. Laws, c. 186, § 24; 57 Del. Laws, c. 148, §§ 27-29; 59 Del. Laws, c. 106, § 12; 60 Del. Laws, c. 371, §§ 3-12; 63 Del. Laws, c. 25, § 14; 63 Del.

PART II.    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.    Indemnification of Directors and Officers

        In accordance with the Illinois Business Corporation Act (being Chapter 805, Act 5 of the Illinois Compiled Statutes), Articles 9 and 10 of Main Street's articles of incorporation provide for indemnification as follows:

        Article 9.    Each person who is or was a director or officer of Main Street and each person who serves or served at the request of Main Street as a director, officer or partner of any other enterprise shall be indemnified by Main Street in accordance with, and to the fullest extent authorized by, the Illinois Business Corporation Act of 1983, as the same now exists or may be hereafter amended. No amendment to or repeal of this Article shall apply to or have any effect on the rights of any individual referred to in this Article for or with respect to acts or omissions of such individual occurring prior to such amendment or repeal.

        Article 10.    To the fullest extent permitted by the Illinois Business Corporation Act of 1983, as the same exists or may hereafter be amended, a director of Main Street shall not be personally liable to Main Street or its stockholders for monetary damages for breach of fiduciary duty of a director.

        Section 7.1 of Main Street's bylaws provides as follows:

        Section 7.1.1. Actions, Suits or Proceedings Other than by or in the Right of Main Street.    Main Street shall 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, whether civil, criminal, administrative or investigative (other than an action by or in the right of Main Street) by reason of the fact that he or she is or was a director, officer, employee or agent of Main Street, or is or was serving at the request of Main Street as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her or on his or her behalf in connection with such action, suit or proceeding and any appeal therefrom, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of Main Street, and, with respect to a criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of Main Street or, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct law was unlawful.

        The Illinois Business Corporation Act provides for indemnification of officers, directors, employees and agents as follows:

        5/8.75 Indemnification of Officers, Directors, Employees and Agents; Insurance.    (a) 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, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or who 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 (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner he or she 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 or her conduct was

II-1



unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation or, with respect to any criminal action or proceeding, that the person had reasonable cause to believe that his or her conduct was unlawful.

        (b)   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 or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person 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 (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, provided that no indemnification shall be made with respect to any claim, issue, or matter as to which such person has been adjudged to have been liable to the corporation, unless, and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper.

        (c)   To the extent that a present or former director, officer or employee of a corporation has been successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to in subsections (a) and (b), or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith if the person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation.

        (d)   Any indemnification under subsections (a) and (b) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case, upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because he or she has met the applicable standard of conduct set forth in subsections (a) or (b). Such determination shall be made with respect to a person who is a director or officer at the time of the determination: (1) by the majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, (2) by a committee of the directors designated by a majority vote of the directors, even though less than a quorum, (3) if there are no such directors, or if the directors so direct, by independent legal counsel in a written opinion, or (4) by the shareholders.

        (e)   Expenses (including attorney's fees) incurred by an officer or director in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this Section. Such expenses (including attorneys' fees) incurred by former directors and officers or other employees and agents may be so paid on such terms and conditions, if any, as the corporation deems appropriate.

        (f)    The indemnification and advancement of expenses provided by or granted under the other subsections of this Section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of shareholders or disinterested directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

        (g)   A corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture,

II-2


trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of this Section.

        (h)   If a corporation indemnifies or advances expenses to a director or officer under subsection (b) of this Section, the corporation shall report the indemnification or advance in writing to the shareholders with or before the notice of the next shareholders meeting.

        (i)    For purposes of this Section, references to "the corporation" shall include, in addition to the surviving corporation, any merging corporation (including any corporation having merged with a merging corporation) absorbed in a merger which, if its separate existence had continued, would have had the power and authority to indemnify its directors, officers, and employees or agents, so that any person who was a director, officer, employee or agent of such merging corporation, or was serving at the request of such merging corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section with respect to the surviving corporation as such person would have with respect to such merging corporation if its separate existence had continued.

        (j)    For purposes of this Section, reference to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries. A person who acted in good faith and in a manner he or she reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interest of the corporation" as referred to in this Section.

        (k)   The indemnification and advancement of expenses provided by or granted under this Section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of that person.

        (l)    The changes to this Section made by this amendatory Act of the 92nd General Assembly apply only to actions commenced on or after the effective date of this amendatory Act of the 92nd General Assembly. (Last amended by P.A. 92-0033, L. '01, eff. 7-1-01.)

        Main Street has purchased $10 million of insurance coverage with respect to any liability incurred by its directors and officers as a result of actions taken by them in such capacities. In addition, Main Street maintains fiduciary liability coverage up to a $5 million limit and trust errors and omissions coverage up to a limit of $6 million.

Item 22.    Undertakings

        The undersigned registrant hereby undertakes:

        (a)   To file during any period in which offers and sales are being made, a post-effective amendment to this registration statement:

        (b)   That for the purpose of determining any liability under the Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (c)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

        The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities and Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to, and meeting the requirements of, Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

        The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

II-5



        The undersigned registrant hereby undertakes that every prospectus: (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Act 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 Act 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 court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

        The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the proxy statement-prospectus pursuant to items 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in the documents filed subsequent to the effective date of this registration statement through the date of responding to the request.

        The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
