FEBRUARY , 2002 Dear Shareholder: You are cordially invited to attend the special meeting of Shareholders of Mercantile Bancorp, Inc., which will be held on March 19, 2002, at 6:00 p.m. local time. The special meeting will be held at Mercantile's main office, located at 8144 Walnut Hill Lane, Suite 180, Dallas, Texas. At the special meeting, you will be asked to consider and vote on approval of an Agreement and Plan of Merger, dated as of November 29, 2001, between Mercantile and The Colonial BancGroup, Inc. The merger agreement provides for us to merge with BancGroup. In the merger, you will receive whole shares of BancGroup common stock in exchange for shares of Mercantile common stock held by you. The exchange ratio, or number of shares of BancGroup common stock you will receive for each share of Mercantile common stock you own, will be determined by multiplying the number of shares of Mercantile common stock you own immediately before the merger is completed by 3.4808. In other words, BancGroup will exchange approximately 3.4808 shares of its common stock for each share of Mercantile common stock. This amount is subject to adjustment based upon the market value of BancGroup common stock during the trading period shortly before the merger. Cash will be paid for any fractional shares. The affirmative vote of the holders of at least two-thirds of the outstanding shares of Mercantile common stock is required to approve the merger agreement. The second purpose of the meeting is to consider and vote upon approval of certain proposed payments to Roy J. Salley, the Chief Executive Officer of Mercantile and First Mercantile Bank, N.A., to the extent that such payments may constitute "parachute payments" under Section 280G of the Internal Revenue Code. These payments are separate from and do not affect the amounts to be received by Mercantile shareholders pursuant to the merger agreement. The board of directors of Mercantile, excluding Mr. Salley, has unanimously recommended approval of the 280G payments to Mr. Salley. The affirmative vote of the holders of at least 75% of the outstanding shares of Mercantile common stock, excluding shares owned by Mr. Salley, is required to approve the 280G payments to Mr. Salley. This proxy statement-prospectus provides detailed information about the merger, the terms of the merger agreement and the formula for converting shares of Mercantile common stock into shares of BancGroup common stock in the merger. In addition, detailed information regarding the 280G payments to Mr. Salley is also provided in this proxy statement - prospectus. Please read carefully the entire proxy statement-prospectus. You can find additional information about BancGroup from documents filed with the Securities and Exchange Commission. Your board of directors has unanimously approved the merger agreement as being in the best interests of Mercantile shareholders and recommends that you vote "FOR" the approval of the merger agreement. The Board of Directors believes that the 280G payments are in the best interests of Mercantile and its shareholders, and unanimously recommends that you vote "FOR" approval and adoption of the proposal to make the 280G payments. Accordingly, your vote is important no matter how large or small your holdings may be. Whether or not you plan to attend the special meeting, you are urged to complete, sign and promptly return the enclosed proxy card to assure that your shares will be voted at the special meeting. If you attend the special meeting, you may vote in person if you wish, and your proxy will not be used. Sincerely, /s/ JOE LONGBOTHAM _____________________________________ JOE LONGBOTHAM Chairman of the Board Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the Bancgroup common stock to be issued in the merger or determined if this proxy statement-prospectus is truthful or complete. Any representation to the contrary is a criminal offense. [LOGO] First Mercantile Bank 8144 Walnut Hill Lane Suite 180 Dallas, Texas 75231 (214) 692-1717 MERCANTILE BANCORP, INC.

After reviewing this document, indicate on your proxy card how you want to vote, and sign, date, and mail it in the enclosed envelope as soon as possible to ensure that your shares will be represented at the special meeting. If you sign, date, and send in your proxy and do not indicate how you want to vote, your proxy will be voted (i) in favor of the merger agreement and the merger and (ii) in favor of the 280G payments. If you do not sign and send in your proxy, and if you do not attend and cast your vote in person at the special meeting, it will have the effect of voting against the merger and the 280G payments. Q: If my shares are held in "street name" by my broker, will my broker vote my shares for me? A: Yes, if you give your broker instructions on how to do so. Your broker will vote your shares of Mercantile common stock only if you provide your broker with instructions on how to vote. You should instruct your broker how to vote your shares by following the directions your broker provides. If you do not provide instructions to your broker, your shares will not be voted and this will have the effect of voting against the merger and the 280G payments. Q: Can I revoke my proxy and change my mind? A: Yes. You may revoke your proxy up to the time of the special meeting by taking any of the actions explained under "The Special Meeting -- General" on page of this proxy statement-prospectus, including by giving a written notice of revocation, signing and delivering a new later-dated proxy, or by attending the special meeting and voting in person. Q: Can I vote my shares in person? A: Yes. You may attend the special meeting and vote your shares in person rather than signing and mailing your proxy card. Q: Should I send in my stock certificates now? A: No. After the merger is completed, BancGroup or its exchange agent will send you written instructions explaining how you exchange your Mercantile common stock certificates for certificates representing shares of BancGroup common stock. Q. When do you expect the merger to be completed? A. We expect the merger to be completed in the first quarter of 2002. However, the timing of the completion of the merger is dependent on the merger agreement being approved by our shareholders as well as the approval of certain bank regulatory agencies. Q: Whom can I call with questions? A: If you want additional copies of this document, or if you want to ask any questions about the merger or the 280G payments, you should contact: Malcolm Holland, President of First Mercantile Bank, Telephone: (214) 692-1717. i SUMMARY This summary highlights selected information from this proxy statement-prospectus. It does not contain all of the information that will be important to you as you consider your vote. You should carefully read the entire document and the other documents to which we refer. These will give you a more detailed description of the transaction that we are proposing. For more information about BancGroup, see "Where You Can Find More Information" (page ). Each item in this summary refers to the pages where that subject is discussed in greater detail elsewhere in the proxy statement-prospectus. In this section, the terms "we" and "us" refer to Mercantile and "you" refers to owners of record of Mercantile common stock on , 2002, the record date. The Companies [LOGO] The Colonial BancGroup, Inc. One Commerce Street Post Office Box 1108 Montgomery, Alabama 36101 (334) 240-5000 BancGroup is a financial holding company whose wholly-owned subsidiary, Colonial Bank, provides corporate and retail banking services and products in Alabama, Florida, Georgia, Tennessee, Texas and Nevada. As of December 31, 2001, BancGroup's total assets were approximately $13.2 billion, deposits were approximately $8.3 billion and shareholders' equity was approximately $865 million. [LOGO] First Mercantile Bank Mercantile Bancorp, Inc. 8144 Walnut Hill Lane, Suite 180 Dallas, Texas 75231 (214) 692-1717 Mercantile is a bank holding company whose indirect and wholly-owned subsidiary, First Mercantile Bank, N.A., provides corporate and retail banking services principally in Dallas, Texas. As of September 30, 2001, Mercantile's total assets were about $346.3 million, deposits were about $297.9 million and shareholders' equity was about $24.6 million. The Merger Pursuant to the merger agreement, Mercantile will merge with and into BancGroup and the separate legal existence of Mercantile will cease. As a result of the merger, Mercantile shareholders will become stockholders of BancGroup. We encourage you to read the entire merger agreement, which is attached as Appendix A. What Mercantile shareholders will receive in the merger (page ) When the merger becomes effective, Mercantile will cease to exist as a separate entity and you, as a shareholder of Mercantile, will be entitled to receive shares of BancGroup common stock. The exchange ratio, or the amount of BancGroup common stock that you will receive, will be determined as follows: . if the Market Value, which is an average of closing prices for BancGroup common stock during a fixed period before the close of the merger, of BancGroup common stock is between $11.00 and $15.00 per 1 share, then Mercantile shareholders will receive 3.4808 shares of BancGroup common stock for each share of Mercantile common stock owned just before the merger becomes effective; . if the Market Value of BancGroup common stock is less than $11.00, Mercantile shareholders will receive the number of shares of BancGroup common stock equal to: $38.29 the number of shares of Mercantile common stock owned just before the ---- X merger becomes effective; and Market Value . if the Market Value of BancGroup common stock is more than $15.00, Mercantile shareholders will receive the number of shares of BancGroup common stock equal to: $52.21 the number of shares of Mercantile common stock owned just before the ---- X merger becomes effective. Market Value These formulas are designed to adjust the number of shares you receive depending on whether the value of BancGroup common stock rises or falls before the merger becomes effective. For example, if just before the merger becomes effective, the Market Value of BancGroup common stock is $16.00 per share and you owned 100 shares of Mercantile common stock, then you would receive: $52.21 3.26 X 100 shares = 326 shares of BancGroup common stock. ----- = $16.00 If the market value of BancGroup common stock were $10.00, then you would receive: $38.29 3.82 X 100 shares = 382 shares of BancGroup common stock. ----- = $10.00 In the event that a business combination transaction is announced in which BancGroup is the target, the exchange rate will be fixed at 3.4808, irrespective of the Market Value of BancGroup common stock. BancGroup will not issue fractional shares in the merger. If the number of shares you are to receive is not a whole number, you will receive cash in an amount equal to the fractional share multiplied by the Market Value of BancGroup common stock instead of the fractional share. Treatment of Mercantile Options Holders of options to acquire shares of Mercantile common stock will have their options treated in one of the following manners: . each Mercantile option holder may elect to participate in a cash free exchange of his Mercantile options for BancGroup common stock by providing written notice to BancGroup, at least five days prior to the effective date, of the option holder's desire to exchange his or her Mercantile options for BancGroup common stock; . each Mercantile option holder may elect to receive cash for the holder's Mercantile options by providing written notice to Mercantile, at least five days prior to the effective date, of the option holder's desire to receive cash for his or her Mercantile option; or . if a Mercantile option holder does not notify BancGroup of the option holder's desire to exchange Mercantile options for BancGroup common stock or cash, then BancGroup will assume the Mercantile options held by the Mercantile option holder in accordance with the Mercantile stock option plan. 2 Mercantile option holders who elect to exchange their Mercantile options for BancGroup common stock will receive the number of shares of BancGroup common stock equal to the value of such holder's Mercantile options, with cash in lieu of any fractional shares. Mercantile option holders who elect to exchange their Mercantile options for cash will receive an amount of cash equal to the value of such holder's Mercantile options. For a discussion regarding the calculation of the value of the Mercantile options, see "Proposal 1: Approval of the Merger Agreement--Treatment of the Mercantile Options" beginning on page . Officers of Mercantile who hold Mercantile options may be eligible to receive a cash bonus in connection with the exchange of their Mercantile options for shares of BancGroup common stock or cash. See "Proposal 1: Approval of the Merger Agreement--Interests of Certain Persons in the Merger--Assumption of Mercantile Options" beginning on page . Comparative Market Prices (page ) BancGroup common stock is traded on the New York Stock Exchange. On November 29, 2001, the last trading day before we announced the merger, the closing price of BancGroup common stock was $14.00. On January 23, 2002, BancGroup common stock closed at $14.57. Mercantile common stock is not publicly traded. Mercantile is not aware of any trades of any shares of Mercantile common stock. The only sales of Mercantile common stock known to management of Mercantile are original issuances of Mercantile common stock by Mercantile to Mercantile shareholders. The last known transaction before November 29, 2001, the last business day before the merger was announced, was September 10, 2001 in connection with Mercantile's acquisition of TownBank, N.A. pursuant to which Mercantile sold shares of Mercantile common stock for $27.00 per share. The following table summarizes the comparative values of the two stocks just before the merger agreement was signed and the BancGroup equivalent price per share of Mercantile common stock. Equivalent price per Mercantile's BancGroup(1) Mercantile(2) share(3) ------------ ------------- -------------------- $14.00... $27.00 $48.73 -------- (1) Closing price on November 29, 2001. (2) Price obtained for shares sold on September 10, 2001. (3) If the merger had closed on November 29, 2001, you would have received 3.4808 shares of BancGroup common stock for each share of Mercantile common stock you owned on that date. Mercantile's Reasons for the Merger (page ) We believe that the merger is in your best interest. We considered a number of factors in deciding to approve and recommend the terms of the merger agreement to you. These factors included the following: . the overall terms of the proposed transaction; . our need for greater access to capital to support growth; . our need to provide additional banking related services and products to meet the expanding needs of our customers; . the fact that the merger will enable you to exchange your shares of Mercantile common stock (for which there is no established public trading market) for shares of BancGroup common stock, a larger and more diversified entity, whose stock is widely held and actively traded; We also took into account an opinion received from an independent financial advisor, SAMCO Capital Markets, a Division of Service Asset Management Company, that the terms of the exchange ratio are fair from a 3 financial point of view, to you. In our deliberations, we did not assign any relative or specific weight to any of the factors that are discussed above, and individual members of our board of directors may have given different weights to different factors as they were discussed. In addition, the discussion of the information above and factors we considered is not intended to be exhaustive of the factors considered. The Shareholders' Meeting (page ) We will hold a special meeting of our shareholders at 6:00 p.m. local time, on Tuesday, March 19, 2002 at our main office located at 8144 Walnut Hill Lane, Suite 180, Dallas, Texas. At the special meeting, we will ask our shareholders: . to approve the merger agreement; . to approve certain proposed payments to Roy J. Salley, the Chief Executive Officer of Mercantile and First Mercantile Bank, to the extent such payments may constitute "parachute payments" within the meaning of Section 280G of the Internal Revenue Code, generally referred to as the 280G payments; and . to act on any other matters that may be properly put to a vote at the special meeting. Our Recommendations to our Shareholders (page ) Your board of directors believes that the merger agreement and the 280G payments are fair to you and in your best interests, and unanimously recommends that you vote "FOR" the proposal to approve the merger agreement and "FOR" approval of the proposal to make the 280G payments. Record Date; Voting Power (page ) You may vote at the special meeting if you owned shares of Mercantile common stock as of the close of business on , 2002. You will have one vote for each share of Mercantile common stock you owned on that date. Vote Required (page ) If a quorum is present at the special meeting, then the affirmative vote of at least two-thirds of the outstanding shares will be sufficient to approve the merger agreement. In order to approve the 280G payments to Mr. Salley, the holders of more than 75% of all of the outstanding shares of Mercantile common stock, excluding those shares held or constructively owned by Mr. Salley, must approve the 280G payments. A quorum consists of a majority of the shares outstanding on the record date. On the record date, 1,336,752 shares of Mercantile common stock were outstanding. The directors, executive officers and other affiliates of Mercantile own 304,730 shares of Mercantile common stock representing approximately 22.80% of the outstanding shares. These individuals have agreed with BancGroup to vote their shares in favor of the merger agreement and, with the exception of Mr. Salley who owns 100 shares and will abstain from the vote on the proposal to approve the 280G payments, have expressed their intention to vote for the 280G payments. In this regard, holders of at least an additional 586,439 shares of Mercantile common stock must vote "FOR" the merger agreement and holders of at least an additional 697,860 shares of Mercantile common stock must vote "FOR" the 280G payments. Exchange of Certificates (page ) Shortly after we complete the merger, you will receive detailed instructions on how to exchange your shares. PLEASE DO NOT SEND US ANY STOCK CERTIFICATES UNTIL YOU RECEIVE THOSE INSTRUCTIONS. 4 Conditions to Completion of the Merger (page ) The completion of the merger depends on meeting a number of conditions, including the following: . the shareholders of Mercantile must approve the merger agreement; . the receipt of all required regulatory approvals and any waiting periods must have passed; . no governmental order blocking completion of the merger, and no proceedings by a government body trying to block the merger; . all of the representations and warranties of Mercantile and BancGroup must be true and correct including the representation by Mercantile that no payments to any employees of Mercantile will fail to be deductible by virtue of Section 280G of the Code; . the existence of no material adverse changes in the results of operations, financial conditions or affairs of either Mercantile or BancGroup; . the shares of BancGroup common stock to be issued in the merger have been approved for listing on the New York Stock Exchange; . the holders of no more than 10% of the outstanding shares of Mercantile common stock have elected to dissent from the merger; . certain officers and directors of Mercantile must have delivered affiliate agreements to BancGroup; . the delivery of an executed employment agreement to BancGroup by each of Roy J. Salley, C. Malcolm Holland and Michael A. Kowalski; . the completion of the merger on or before August 31, 2002; and . the receipt of certain professional opinions, including a letter from the firm of SAMCO that the exchange ratio is fair, from a financial point of view, to our shareholders and a letter from PricewaterhouseCoopers LLP that the merger will qualify as a tax free reorganization. Unless prohibited by law, either Mercantile or BancGroup could elect to waive a condition that has not been satisfied and complete the merger anyway. We cannot be certain whether or when any of these conditions will be satisfied, or waived where permissible, or that we will complete the merger. Termination of the Merger Agreement (page ) The two companies can agree at any time to terminate the merger agreement before completing the merger, even if the shareholders of Mercantile have already voted to approve it. Either company can also terminate the merger agreement: . if the other party has materially breached the merger agreement and has not cured the breach; . if the merger has not been completed by August 31, 2002, (provided that the failure to complete has not been caused by the breach of the company electing to terminate); or . if Mercantile enters into a binding agreement with any third party to merge with, or sell control to, that third party. In that event, Mercantile may be required to pay liquidated damages to BancGroup. Federal Income Tax Consequences (page ) We expect that neither of the two companies nor Mercantile's shareholders will recognize any gain or loss for U.S. federal income tax purposes as a result of the merger, except in connection with any cash that Mercantile's shareholders may receive for fractional shares. BancGroup has received an opinion from PricewaterhouseCoopers LLP that this will be the case. The opinion will not bind the Internal Revenue Service, which could take a different view. 5 This nonrecognition of gain or loss tax treatment will not apply to Mercantile's shareholders who dissent from the transaction and receive cash instead of BancGroup common stock for their Mercantile common stock as provided under Texas law. The procedures for exercising dissenters' rights are discussed at page . None of the currently outstanding options to purchase Mercantile common stock are qualified as "incentive" stock options. Therefore, holders of such options will recognize taxable income if and when they exercise such options equal to the fair market value of the stock subject to the option over the exercise price at the date of exercise. Mercantile, or BancGroup if such options are exercised after the completion of the merger, would be entitled to a tax deduction for the same value. If a Mercantile option holder chooses to exchange his or her options for cash or for BancGroup common stock, then such holder will recognize taxable income for the value of such cash or stock and taxable income for the cash bonus that will also be paid to such a holder. See "Proposal 1: Approval of the Merger Agreement--Treatment of Mercantile Options." Determining the actual tax consequences to you as an individual taxpayer can be complicated. For example, the opinion referred to above does not address any tax issues arising under state law. The overall tax treatment applicable to you will depend on your specific situation and many variables not within our control. You should consult your own tax advisor for a full understanding of the merger's tax consequences to you. See "Proposal 1: Approval of the Merger Agreement--Federal Income Tax Consequences" for a more thorough discussion of the tax consequences of the merger. Accounting Treatment (page ) The merger will be accounted for as a purchase. The purchase price will be assigned to the fair value of the net tangible and intangible assets acquired, with any amounts in excess thereof being assigned to "goodwill." Goodwill will be capitalized unless and until it is deemed to be impaired, in which case the impairment will be measured and any such amount will be charged against current earnings. Interests of Persons Involved in the Merger that are Different from Yours (page ) Certain directors, executive officers and employees of Mercantile have interests in the merger that are different from your interests. These differing interests include the following: . BancGroup will assume outstanding options to acquire Mercantile common stock. Certain officers and directors of Mercantile currently hold options to acquire 232,000 shares of Mercantile common stock. In the merger, these options will become rights to acquire BancGroup common stock in amounts and at prices determined by the exchange ratio applicable in the merger generally. Alternatively, the merger agreement allows the holders of these options to exchange some or all of their options for cash or for BancGroup common stock without paying an exercise price. If a holder chooses to participate in the "cash free exchange", then he or she will receive an amount of cash or BancGroup common stock equal to the value of such holder's options less the exercise price of such options. Additionally, if an officer elects to participate in the "cash free exchange," then that officer will also receive a cash bonus equal to 34% of the value of such options exchanged. For a discussion regarding the calculation of the value of the Mercantile options, see "Proposal 1: Approval of the Merger Agreement--Treatment of the Mercantile Options" beginning on page . . Mercantile currently indemnifies its directors and certain officers, employees and agents against loss from claims arising out of their position with Mercantile. For a period of three years after the merger, BancGroup will, subject to some limitations, continue to indemnify those persons against claims that arise from the period when they worked for, or served as directors of, Mercantile. BancGroup has also agreed to use commercially reasonable efforts to continue insurance coverage of liability for a period of three years after the merger for directors and executive officers for events which occur before the merger. 6 . Upon completion of the merger, Mercantile employees will either become employees of BancGroup or one of its subsidiaries and become eligible for BancGroup's employee benefits, or they will be eligible to receive severance benefits under BancGroup's severance policy. . Roy J. Salley, Chief Executive Officer of Mercantile and First Mercantile Bank, has entered into an employment agreement with BancGroup that becomes effective when, and if, the merger is completed. The agreement with Mr. Salley provides for a term of three to five years, base annual compensation of $210,000, eligibility to receive 10,000 shares of BancGroup common stock in the form of a restricted stock award, eligibility to receive options to acquire 25,000 shares of BancGroup common stock, an incentive based cash bonus of up to $75,000, and various other benefits. This agreement also contains a covenant prohibiting Mr. Salley from competing with BancGroup for a period of time following termination of employment. . C. Malcolm Holland, President of First Mercantile Bank, has entered into an employment agreement that will become effective when, and if, the merger is completed. The agreement with Mr. Holland provides for a term of three to five years, base annual compensation of $190,000, eligibility to receive 5,000 shares of BancGroup common stock in the form of a restricted stock award, eligibility to receive options to acquire 15,000 shares of BancGroup common stock, an incentive-based cash bonus of up to $50,000, and various other benefits. This agreement also contains a covenant prohibiting Mr. Holland from competing with BancGroup for a period of time following termination of employment. . Michael A. Kowalski, Executive Vice President and Chief Financial Officer of First Mercantile Bank, has entered into an employment agreement that will become effective when, and if, the merger is completed. The agreement with Mr. Kowalski provides for a term of two years, base annual compensation of $115,000, the right to receive options to acquire 5,000 shares of BancGroup common stock, and various other benefits. This agreement also contains a covenant prohibiting Mr. Kowalski from competing with BancGroup for two years following the Effective Date. . Mercantile's directors and certain executive officers have entered into "affiliate agreements" with BancGroup regarding various issues associated with the merger. These agreements provide that the director or executive officer would, among other things: -- agree to vote his or her shares for the merger; -- not distribute BancGroup common stock issued in connection with the merger except in accordance with certain rules of the SEC; -- support the business of Colonial Bank after the merger; and -- not sell, transfer or otherwise encumber 25% of the BancGroup common stock such person receives in connection with the merger for two years following the merger. Additionally, Mercantile directors who are not also employees of Mercantile agreed generally not to compete with Colonial Bank for a period which is the longer of four years following the merger or two years after such person ceases to be a regional or local director for Colonial Bank and will be entitled to receive a cash payment of $125,000 for this non-compete agreement. . Prior to the signing of the merger agreement with BancGroup, Mercantile's board of directors agreed to pay Roy J. Salley a cash bonus if certain conditions were satisfied. These conditions included the successful sale of Mercantile at a price of greater than $40.00 per share. Pursuant to that agreement, Mr. Salley will receive at the closing of the merger a cash bonus equal to 0.75% of the merger consideration paid to Mercantile shareholders. The exact amount of the cash bonus cannot be determined until the closing of the merger, but it will be no more than $523,439. 7 Fairness Opinion (page ) In deciding to approve the merger, your board of directors considered the opinion of a financial advisor, SAMCO, that, as of the date of the opinion, the exchange ratio is fair, from a financial point of view, to Mercantile shareholders. We have attached as Appendix C the written opinion of SAMCO dated as of the date of this proxy statement-prospectus. You should read it carefully to understand the assumptions made, matters considered and limitations of the review undertaken by SAMCO in providing its opinion. Dissenters' Rights (page ) Mercantile shareholders entitled to vote at the special meeting are entitled to exercise "dissenters' rights" of appraisal under Texas law. These rights entitle a shareholder to "dissent" from the transaction and, by strictly following the requirements fixed by law, receive "fair value" for their stock. The fair value may ultimately be determined in a judicial proceeding, the result of which cannot be predicted with certainty. Dissenting shareholders who receive cash for their stock will likely be subject to federal income tax treatment that differs from that available to shareholders who receive BancGroup common stock. The text of the applicable Texas statutes is set forth in Appendix B. Your Rights as a Stockholder Will Change (page ) Once the proposed merger occurs, Mercantile shareholders who do not dissent from the merger will become stockholders of BancGroup. In this regard, your rights as a stockholder of BancGroup will be governed by Delaware corporate law instead of Texas corporate law, and they will be further governed by BancGroup's Certificate of Incorporation and Bylaws instead of Mercantile's Articles of Incorporation and Bylaws. Because of certain differences between Texas corporate law and Delaware corporate law, and between Mercantile's Articles of Incorporation and Bylaws and BancGroup's Certificate of Incorporation and Bylaws, your current rights as a shareholder will change after the merger. See "Comparative Rights of Stockholders." BancGroup Common Stock is Publicly Traded and Most of You Will Be Free to Trade the Shares of BancGroup Common Stock that You Receive in the Merger Whereas Mercantile Common Stock is Not Publicly Traded (page ) BancGroup common stock is publicly traded on the New York Stock Exchange under the symbol "CNB." BancGroup will register the shares of its common stock to be issued in the merger and, as a result, most of you may sell such shares without restriction; however, securities laws impose certain restrictions on affiliates, generally directors, executive officers and 10% shareholders of BancGroup, which after the merger may include certain Mercantile shareholders, regarding how and when they may trade BancGroup common stock. Shares of Mercantile common stock are not registered with the SEC and are not listed on any exchange or quoted on any automated quotation system. As a result, Mercantile common stock is not freely tradable. See "Proposal 1: The Merger--Resale of BancGroup Common Stock Issued in the Merger." Approval of the 280G Payments In connection with the merger, Roy J. Salley, the Chief Executive Officer of Mercantile and First Mercantile Bank, is entitled to receive certain payments. These payments consist generally of the acceleration of Mr. Salley's vesting in his Mercantile options, a cash bonus equal to 34% of the value of his Mercantile options exchanged for either cash or Bancgroup common stock, to the extent he elects to do so, and a performance cash bonus in connection with the sale of Mercantile for more than $40.00 per share. You are being asked to approve that portion of any payment that would cause the payment to constitute a "parachute payment" under Section 280G of the Internal Revenue Code. Mr. Salley may receive payments of up to $719,822 without having such 8 payments constitute parachute payments. At closing and irrespective of the outcome of the Mercantile shareholder's vote on proposal 2 to approve the 280G payments, Mr. Salley will receive payments equaling $719,822, which will be comprised of the acceleration of his vesting in his Mercantile options, the payment equal to 34% of the value of his Mercantile options exchanged for cash or Bancgroup common stock, in the event he elects to do so, and, to the extent those two payments do not exceed $719,822, that portion of the performance cash bonus that when added to the first two payments would equal $719,822. If the Mercantile shareholders approve proposal 2, Mr. Salley will receive the balance of the performance cash bonus at closing. Until the Market Value of the Bancgroup common stock is established, the exact amounts of the payments, including any 280G payment, to Mr. Salley cannot be determined.

Recent Developments--Mercantile Shortly after the announcement of the merger agreement by Bancgroup, Mercantile was contacted by Hovde Financial, LLC, an investment banking firm. Hovde Financial asserted that it was entitled to a fee based on an engagement letter entered into between Hovde Financial and Mercantile in November 1999. Mercantile believes that it effectively terminated the engagement letter and that Hovde Financial is not entitled to any fees in connection with Mercantile's business combination with Bancgroup. Mercantile, however, after consultation with Bancgroup and to avoid costly litigation and to close the merger as promptly as possible, has reached a settlement with Hovde Financial concerning its claims. Mercantile has agreed to pay $425,000 to Hovde Financial at closing in full satisfaction of any claims Hovde Financial has or, in the future, may assert regarding the merger. 11 A WARNING ABOUT FORWARD-LOOKING STATEMENTS We and BancGroup make forward-looking statements in this document and in BancGroup's public documents to which it refers. When we or BancGroup use words such as "anticipate," "believe," "estimate," "may," "intend," "expect," "will," "should," "seeks" or other similar expressions we or BancGroup refer to events or conditions subject to risks and uncertainties. When considering those forward-looking statements, you should keep in mind the risks, uncertainties and other cautionary statements made in this proxy statement-prospectus. You should not place undue reliance on any forward-looking statement, which speaks only as of the date made. In addition to the risks identified below, you should refer to BancGroup's public documents for specific risks which could cause actual results to be significantly different from those expressed or implied by those forward-looking statements. Some factors which may affect the accuracy of the forward-looking statements apply generally to the financial services or real estate industries, while other factors apply directly to us or BancGroup. Any number of important factors which could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: . expected cost savings from reorganization into BancGroup are not fully realized; . deposit attrition, customer loss, or revenue loss following the reorganization into BancGroup are greater than expected; . deposit attrition, customer loss, or revenue loss in the ordinary course of business; . increases in competitive pressure in the banking industry; . changes in the interest rate environment which reduce margins; . general economic conditions, either nationally or regionally, that are less favorable than expected, resulting in, among other things, a deterioration in credit quality; . changes which may occur in the regulatory environment; . a significant rate of inflation or deflation; . acts of terrorism, such as the events of September 11, 2001, and war; and . changes in the securities markets. Many of these factors are beyond our control and beyond the control of BancGroup. For a discussion of factors that could cause BancGroup's actual results to differ, please see the discussions in the sections entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations" in its Annual Report on Form 10-K for the year ended December 31, 2000 and its Quarterly Reports on Form 10-Q for the periods ended March 31, 2001, June 30, 2001 and September 30, 2001. 12 THE SPECIAL MEETING General This proxy statement-prospectus is being furnished to the shareholders of Mercantile in connection with the solicitation of proxies by the board of directors of Mercantile for use at the special meeting to be held on , 2002, and at any adjournments or postponements thereof. The purpose of the special meeting is to consider and vote upon the following matters: . proposal 1: approve and adopt the merger agreement; . proposal 2: approve the 280G payments to Roy J. Salley, the Chief Executive Officer of Mercantile and First Mercantile Bank; and . any and all other business that may properly come before the special meeting or any adjournments thereof. The board of directors of Mercantile believes that the merger is in the best interests of Mercantile shareholders and unanimously recommends that shareholders vote "FOR" the merger agreement (item 1 on the proxy card). The board of directors of Mercantile believes that the 280G payments to Mr. Salley are in the best interests of Mercantile shareholders and unanimously recommends that shareholders vote "FOR" the 280G payments (item 2 on the proxy card). This proxy statement-prospectus is also furnished by BancGroup in connection with the offer of shares of BancGroup common stock to be issued in the merger. No vote of BancGroup stockholders is required to approve the merger agreement or the issuance of the BancGroup common stock. Record Date; Shares Entitled to Vote; Vote Required for the Merger and the 280G Payments The board of directors of Mercantile has fixed the close of business on , 2002, as the record date for determination of shareholders entitled to vote at the special meeting. There were 266 record holders of Mercantile common stock and 1,336,752 shares of Mercantile common stock outstanding, each entitled to one vote per share, as of the record date. Mercantile is obligated to issue up to an additional 232,000 shares of Mercantile common stock upon the exercise of outstanding Mercantile options. The presence at the special meeting, in person or by proxy, of the holders of a majority of the outstanding shares of Mercantile common stock on the record date is necessary to constitute a quorum for the transaction of business at the special meeting. In the absence of a quorum, the special meeting may be postponed from time to time until Mercantile shareholders holding the requisite number of shares of Mercantile common stock are represented in person or by proxy. The following votes are required to approve the proposal at the special meeting: . in order to approve and adopt the merger agreement, the affirmative vote of the holders of at least two-thirds of the outstanding shares of Mercantile common stock, whether or not present or represented at the special meeting, is required to vote "FOR" proposal 1 to approve the merger agreement; and . in order to approve the 280G payments to the Chief Executive Officer of Mercantile, the affirmative vote of holders of more than 75% of the voting power of all outstanding shares of Mercantile common stock, excluding those shares held or constructively owned by the Chief Executive Officer, is required to vote "FOR" proposal 2 to approve the 280G payments. Broker non-votes and abstentions will not be counted as votes "FOR" or "AGAINST" either proposal and, as a result, such non-votes will have the same effect as votes cast "AGAINST" the merger agreement and the 280G payments. Each holder of record of shares of Mercantile common stock is entitled to cast, for each share registered in his or her name, one vote on the merger agreement and the 280G payments. 13 As of the record date, directors of Mercantile owned 304,730 shares of Mercantile common stock representing approximately 22.80% of the outstanding shares. These individuals have agreed with BancGroup to vote their shares in favor of the merger agreement and indicated their intention to vote in favor of the 280G payments. Mr. Salley will abstain from voting his 100 shares of Mercantile common stock on the proposal to approve the 280G payments. If the merger agreement is approved at the special meeting, Mercantile is expected to merge with and into BancGroup promptly after the other conditions to the merger agreement are satisfied. See "Proposal 1: Approval of the Merger Agreement--Conditions of Consummation of the Merger." THE BOARD OF DIRECTORS OF MERCANTILE URGES THE SHAREHOLDERS OF MERCANTILE TO EXECUTE AND RETURN THE ENCLOSED PROXY CARD AS SOON AS POSSIBLE AND UNANIMOUSLY RECOMMENDS THAT THE SHARES REPRESENTED BY THE PROXY BE VOTED IN FAVOR OF THE MERGER AGREEMENT AND THE 280G PAYMENTS. Solicitation, Voting and Revocation of Proxies In addition to soliciting proxies by mail, directors, officers and other employees of Mercantile, without receiving special compensation therefor, may solicit proxies from Mercantile shareholders by telephone, by email or other electronic means, by facsimile or in person. Arrangements will also be made with brokerage firms and other custodians, nominees and fiduciaries, if any, to forward solicitation materials to any beneficial owners of shares of Mercantile common stock. Mercantile will bear the cost of assembling and mailing this proxy statement-prospectus and other materials furnished to shareholders of Mercantile. It will also pay all other expenses of solicitation, including the expenses of brokers, custodians, nominees, and other fiduciaries who, at the request of Mercantile, mail material to, or otherwise communicate with, beneficial owners of the shares held by them. BancGroup will pay all expenses incident to the registration of the BancGroup common stock to be issued in connection with the merger. Mercantile and BancGroup will bear and pay all direct costs and expenses incurred by, or on behalf of, the party in question. Shares of Mercantile common stock represented by a proxy properly signed and received at or prior to the special meeting, unless properly revoked, will be voted in accordance with the instructions on the proxy. If a proxy is signed and returned without any voting instructions, shares of Mercantile common stock represented by the proxy will be voted "FOR" the proposals to approve the merger agreement, the 280G payments and in accordance with the determination of the majority of the board of directors of Mercantile as to any other matter which may properly come before the special meeting, including any adjournment or postponement thereof. A shareholder may revoke any proxy given pursuant to this solicitation by: . delivering to the Secretary of Mercantile, prior to or at the special meeting, a written notice revoking the proxy; . delivering to the Secretary of Mercantile, at or prior to the special meeting, a duly executed proxy relating to the same shares and bearing a later date; or . voting in person at the special meeting. Attendance at the special meeting will not, in and of itself, constitute a revocation of a proxy. 14 All written notices of revocation and other communications with respect to the revocation of Mercantile proxies should be addressed to: Mercantile Bancorp, Inc. 8144 Walnut Hill Lane, Suite 180 Dallas, Texas 75231 Attention: Roy J. Salley Proxies marked as abstentions and shares held in street name which have been designated by brokers on proxy cards as not voted will not be counted as votes cast. Such proxies will, however, be counted for purposes of determining whether a quorum is present at the special meeting. The board of directors of Mercantile is not aware of any business to be acted upon at the special meeting other than consideration of the merger agreement and the 280G payments described herein. If, however, other matters are properly brought before the special meeting, or any adjournments or postponements thereof, the persons appointed as proxies will have the discretion to vote or act on such matters according to their best judgment. Proxies voted in favor of the approval of the merger agreement, or proxies as to which no voting instructions are given, will be voted to adjourn the special meeting, if necessary, in order to solicit additional proxies in favor of the approval of the merger agreement. Proxies voted against the approval of the merger agreement and abstentions will not be voted for an adjournment. See "Adjournment of the Special Meeting." Effect of Merger on Outstanding BancGroup Common Stock At the consummation of the merger, the "Market Value" of BancGroup common stock will be the average of the closing prices of BancGroup common stock as reported by the New York Stock Exchange ("NYSE") on each of the ten consecutive trading days ending on the trading day five trading days immediately preceding the Effective Date. Assuming that no dissenters' rights of appraisal are exercised in the merger, that 1,568,752 shares of Mercantile common stock are outstanding on the Effective Date, which consists of the 1,336,752 shares of Mercantile common stock and options to acquire 232,000 shares of Mercantile common stock outstanding on the date of this proxy statement-prospectus, and the Market Value of BancGroup common stock is between $11.00 and $15.00 per share on the Effective Date, then BancGroup would issue 5,460,511 shares of BancGroup common stock pursuant to the merger. As of November 29, 2001 the closing price of BancGroup common stock was $14.00. If the Market Value of BancGroup common stock is equal to $14.00 on the Effective Date, then approximately 5,460,511 shares of BancGroup common stock will be issued pursuant to the merger. The issuance of 5,460,511 shares of BancGroup common stock would represent approximately 4.5% of the total number of shares of BancGroup common stock outstanding following the merger, not counting any additional shares of BancGroup common stock which BancGroup may issue for reasons unconnected to the merger. Depending on actual events, the foregoing figures may be substantially different as of the Effective Date. 15 PROPOSAL 1: APPROVAL OF THE MERGER AGREEMENT The following sets forth a summary of the material provisions of the merger agreement and the transactions contemplated thereby. The description does not purport to be complete and is qualified in its entirety by reference to the merger agreement, a copy of which is attached hereto as Appendix A, and certain provisions of Texas law relating to the rights of dissenting shareholders, a copy of which is attached hereto as Appendix B. All Mercantile shareholders are urged to read the merger agreement and the appendices in their entirety. The Merger The merger agreement provides that, subject to approval by the shareholders of Mercantile, receipt of necessary regulatory approvals and satisfaction of certain other conditions described below at "Conditions to Consummation of the Merger," Mercantile will merge with and into BancGroup. Upon completion of the merger, the corporate existence of Mercantile will cease, and BancGroup will succeed to the business formerly conducted by Mercantile. BancGroup currently anticipates that First Mercantile Bank will be merged into BancGroup's subsidiary bank, Colonial Bank, after the merger. The timing of such a merger, as well as its actual consummation, is within BancGroup's discretion. First Mercantile Bank and Colonial Bank have entered into an agreement providing for the merger of First Mercantile Bank with and into Colonial Bank, subsequent to the consummation of the merger and receipt of regulatory approvals. Background of the Merger Mercantile was established in 1998 and has enjoyed significant growth since that time. Since inception, the board of directors has focused on analyzing strategic alternatives available to Mercantile and developing Mercantile's franchise. As a part of this continuing analysis, the board of directors sought ways to access additional capital to support Mercantile's growth. One alternative the board considered was a possible business combination transaction. On November 29, 1999, the board of directors engaged Hovde Financial LLC to assist the board in formulating objectives based on the strategic options identified by Hovde Financial. Hovde Financial is an investment banking firm focused exclusively on the financial services industry and specializes in providing investment banking and financial advisory services to banks and thrifts. Representatives of Hovde Financial met with members of the board of directors and executive officers of Mercantile to learn about Mercantile's business and operations. Based on its analysis, Hovde Financial recommended to the board of directors that Mercantile consider a business combination transaction with another financial institution. As a result of Hovde Financial's recommendation, the board authorized Hovde Financial to perform limited marketing of Mercantile. Hovde Financial contacted financial institutions that it believed might have an interest in acquiring Mercantile. However, Mercantile did not receive any indications of interest that were satisfactory to its board of directors and Hovde Financial's engagement was terminated. The board of directors continued to explore strategic alternatives for Mercantile. On May 1, 2001, Mercantile entered into a definitive agreement to acquire TownBank, N.A. in Mesquite, Texas. In connection with the TownBank acquisition, which was completed in September 2001, the board of directors determined that Mercantile would need to find a significant amount of additional capital to continue to grow. In order to access this capital, Mercantile would need either to raise significant additional capital or enter into a business combination transaction. The board of directors assessed whether seeking new sources of capital or finding a merger partner would better serve to maximize shareholder value. Also, the board of directors recognized that a viable and liquid market for shares of Mercantile common stock did not exist and that many shareholders desired increased liquidity in their investments. In evaluating its alternatives, the board of directors sought to provide an alternative that would maximize shareholder value and provide liquidity in their investments. Based on 16 Mercantile's size and the dilutive impact of a common stock offering, the board decided to reinvestigate the possibility of a business combination transaction. In February 2001, Mercantile engaged SAMCO to act as its financial advisor in the TownBank merger and as its placement agent in the private placement of $8 million of trust preferred securities. SAMCO is an investment banking firm that provides financial advice to community banks. Mercantile and SAMCO also discussed the possibility of SAMCO representing Mercantile in negotiations leading to a business combination transaction. On February 28, 2001, Mercantile engaged SAMCO to contact and screen potential buyers, prepare a marketing memorandum, negotiate with potential buyers and assist Mercantile in all aspects of a business combination transaction. From March 2001 through October 2001, SAMCO contacted several financial institutions to discuss the possibility of a business combination transaction with Mercantile. Of the parties contacted, ten indicated an interest in a possible business combination transaction, including BancGroup. On October 3, 2001, representatives of SAMCO flew to Montgomery, Alabama to meet with certain executive officers of BancGroup to discuss the Dallas market generally and the attractiveness of Mercantile's franchise to BancGroup particularly. At the October 16, 2001 Mercantile board of directors meeting, Mr. Salley informed the board that he had met with representatives of a financial institution other than BancGroup that was interested in a business combination transaction with Mercantile. As a result of the meeting, Mr. Salley informed the Board that a letter of intent describing the proposed acquisition of Mercantile was expected from this financial institution. On October 17, 2001, Mercantile received a letter of intent from such other financial institution. On October 25, 2001, representatives of SAMCO met with Mr. Salley to discuss the results of SAMCO's October 3, 2001 meeting with BancGroup and its interest in pursing a business combination transaction with Mercantile. A meeting was arranged with representatives of BancGroup for October 29, 2001. At the meeting on October 29, 2001, certain executive officers of Mercantile met with representatives of BancGroup to discuss a possible business combination transaction. As a result of this meeting, BancGroup and Mercantile agreed to negotiate, in good faith, the terms of a proposed merger agreement. Between October 29, 2001 and November 21, 2001, Mercantile and its legal advisors negotiated the terms and conditions of a definitive merger agreement with BancGroup. The board of directors of Mercantile met on November 21, 2001 to discuss the two competing offers it had received. During the meeting, the board met to review in detail the offer from BancGroup and the existing offer from another financial institution, including the merger agreement and the required ancillary documents and agreements. Mercantile's legal counsel reviewed the terms of the transaction documents proposed by the BancGroup with, and answered questions from, the board of directors. Thereafter, the board of directors considered the benefits and drawbacks, including a review of the financial and other aspects, of a business combination transaction with either party. Based on its discussions, the board of directors concluded that a business combination transaction with BancGroup represented a better opportunity for Mercantile and its shareholders. At the conclusion of the discussion, Mercantile's board of directors voted unanimously to approve the business combination transaction with BancGroup and to approve the merger and the merger agreement transactions described thereby and to recommend that its shareholders vote for approval and adoption of the merger, the merger agreement and the transactions described thereby. Final negotiations continued through November 29, 2001. On November 29, 2001, Mercantile and BancGroup executed the merger agreement and, on November 30, 2001, BancGroup issued a press release announcing the proposed merger. 17 Mercantile's Board of Directors' Reasons for the Merger Mercantile's board of directors believes that the merger is advisable and in the best interests of Mercantile and its shareholders. In reaching this determination, Mercantile's board of directors considered a number of factors including, without limitation, the following: . The transaction would give Mercantile shareholders greater liquidity, as currently no trading market exists for shares of Mercantile common stock, while BancGroup common stock is listed and traded on the New York Stock Exchange. . Mercantile and BancGroup have structured the merger to qualify as a tax free reorganization to Mercantile shareholders. The merger agreement provides that it is a condition to Mercantile's obligations to complete the merger that it will receive the opinion of PricewaterhouseCoopers LLP, that no gain or loss will be recognized by Mercantile shareholders to the extent they receive BancGroup common stock in the merger. See "Proposal 1: Approval of the Merger Agreement--Certain Federal Income Tax Consequences. . The complementary nature of BancGroup's business, services and products with those of Mercantile, and the opportunity to create a combined business that offers a wider variety of services to Mercantile's customers and enhances the ability to attract new customers in the future. . The consideration to be received by Mercantile shareholders in the merger, which Mercantile's board of directors believed to represent an attractive premium and to be fair to Mercantile shareholders from a financial point of view. Mercantile's board of directors' determination was based on, among other things, a comparison of the terms of the proposed transaction with other recent bank mergers and acquisitions, the evaluation of publicly available information regarding BancGroup, the review and evaluation of other information concerning the valuation of banks and analyses of recent bank acquisitions, the review and evaluation of financial information and analyses regarding BancGroup and advice provided by Mercantile's financial advisor, SAMCO. Mercantile's board of directors determined that the premium to be received by the Mercantile shareholders pursuant to the merger agreement represents an attractive premium compared to recent comparable bank transactions in the State of Texas and the Southwest generally, and represented more value than management of Mercantile believed could be generated by remaining independent. . The opinion of SAMCO, Mercantile's financial advisor, that the consideration to be received by Mercantile shareholders in the merger is fair to the Mercantile shareholders from a financial point of view. See "Proposal 1: Approval of the Merger Agreement--Fairness Opinion of Mercantile's Financial Advisor." . Mercantile's ability to provide value to Mercantile shareholders without accessing significant amounts of additional capital. . The ability of Mercantile's management to continue to manage BancGroup's Texas operations upon completion of the merger. . The access to greater capital that the merger provides to facilitate more effectively the continued growth of Mercantile's operations and franchise. . The state of the banking industry generally and the increased competition brought about by consolidation, deregulation and other factors, as well as the financial size and resources necessary to compete in this environment. . BancGroup's record of paying cash dividends to its shareholders over the past 15 years. Mercantile's board of directors has approved the merger agreement and unanimously recommends that Mercantile shareholders vote "FOR" the merger agreement at the special meeting. 18 Fairness Opinion of SAMCO The fairness opinion of Mercantile's financial advisor, SAMCO Capital Markets, a Division of Service Asset Management Company, is described below. The description contains SAMCO's projections, estimates and/or other forward looking statements about the future earnings or other measures of the future performance of BancGroup and Mercantile. You should not rely on any of these statements as having been made or adopted by BancGroup or Mercantile. Subsequent to Mercantile's engagement of SAMCO as placement agent of its trust preferred securities, Mercantile engaged SAMCO as its independent financial advisor in connection with Mercantile's consideration of a possible business combination with a third party. Specifically, based on SAMCO's reputation and qualifications in evaluating financial institutions, Mercantile's board of directors requested that SAMCO render advice and analysis in connection with a possible sale transaction, and to provide an opinion with regard to the fairness--from the perspective of Mercantile shareholders--of the financial terms of any proposed transaction. SAMCO is regularly engaged to provide investment banking services to financial institutions and in the valuation of financial institutions and their securities in connection with mergers and acquisitions, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Over the past two years, SAMCO has been engaged by Mercantile to provide various financial advisory services, including rendering fairness opinions for possible stock issuance, as well as for Mercantile's acquisition of TownBank, SAMCO collected approximately $22,500 in fees related to these services. In addition, SAMCO also served as placement agent for Mercantile's $8 million Trust Preferred Securities offering, receiving fees totaling $208,498. SAMCO was requested to, and did, solicit third party offers to acquire all or any part of Mercantile. In connection with providing its opinion of the financial fairness of the exchange ratio to Mercantile shareholders, SAMCO was specifically instructed by the Mercantile board of directors to provide the board with an evaluation, or fair value appraisal, of the Mercantile common stock. Mercantile's board, together with input from SAMCO, determined that fair value of the Mercantile common stock for the purposes of the evaluation would be based on the value of a pro rata share of Mercantile as a going concern. The fair value should not include any consideration of the impact of the merger on the value of Mercantile. In addition, SAMCO was instructed that in determining the fair value to consider all usual and customary approaches to calculating value, including net asset value, investment value and market value. In making the final determination of fair value, Mercantile's board of directors further instructed SAMCO that fair value is not intended to be derived from a pro forma sale of Mercantile but rather assumes that the Mercantile shareholders are willing to maintain their investment in Mercantile as though the merger had not occurred. Accordingly, the final determination of value should neither assume a sale of 100% of the stock of Mercantile nor include an application of any discount or control premium. As is mentioned above, in addition to providing the evaluation, Mercantile retained SAMCO to render its fairness opinion and conditioned its obligations to perform under the merger agreement on its receipt of a fairness opinion from SAMCO. A copy of the fairness opinion of SAMCO, dated , 2002, which sets forth certain assumptions made, matters considered and limits on the review undertaken by SAMCO, is attached as Appendix C to this proxy statement-prospectus. Mercantile shareholders are urged to read the fairness opinion in its entirety. In arriving at its fairness opinion, SAMCO reviewed and analyzed among other things, the following: . the merger agreement; . the financial statements of Mercantile and First Mercantile Bank; 19 . certain other publicly available financial and other information concerning Mercantile and First Mercantile Bank; . publicly available information concerning other banks and bank holding companies, the trading markets for their securities and the nature and terms of certain other transactions relevant to SAMCO's inquiry; . the competitive and economic outlook for Mercantile's trade area; . the book value and financial condition of Mercantile and First Mercantile Bank; . the future earnings and dividend paying capacity of Mercantile and First Mercantile Bank; and . the prevailing market prices for selected publicly-traded banking organizations in Texas. SAMCO also held discussions with senior management of Mercantile concerning its past and current operations, financial condition and prospects, as well as the results of regulatory examinations. In conducting its review and arriving at its fairness opinion, SAMCO relied upon and assumed the accuracy and completeness of the financial and other information provided to it or publicly available, and did not attempt to independently verify the same. SAMCO did not make or obtain any evaluations or appraisals of the properties of Mercantile, nor did it examine any individual loan credit files. For purposes of the fairness opinion, SAMCO assumed that the merger will have the tax, accounting and legal effects described in this proxy statement-prospectus. SAMCO's fairness opinion is limited to the fairness, from a financial point of view, of the exchange ratio as set forth in the merger agreement. As more fully discussed below, SAMCO considered such financial and other factors as it deemed appropriate under the circumstances, including among others the following: . the historical and current financial position and results of operations of Mercantile and First Mercantile Bank, including interest income, interest expense, net interest income, net interest margin, provision for loan losses, non-interest income, non-interest expense, earnings, dividends, internal capital generation, book value, intangible assets, return on assets, return on shareholders' equity, capitalization, the amount and type of non-performing assets, loan losses and the reserve for loan losses, all as set forth in the financial statements for Mercantile and First Mercantile Bank; . the assets and liabilities of Mercantile and First Mercantile Bank, including the loan, investment and mortgage portfolios, deposits, other liabilities, historical and current liability sources and costs and liquidity; and . the nature and terms of certain other merger transactions involving banks and bank holding companies. SAMCO also took into account its assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuation and its knowledge of the banking industry generally. SAMCO's fairness opinion is necessarily based upon conditions as they existed and can be evaluated on the date of its fairness opinion and the information made available to it through that date. In connection with rendering its fairness opinion, SAMCO performed certain financial analyses, which are summarized below. SAMCO believes that its analysis must be considered as a whole, and that selecting portions of such analysis and the factors considered therein, without considering all factors and analysis, could create an incomplete view of the analysis and the processes underlying the fairness opinion. The preparation of a fairness opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. In its analyses, SAMCO made numerous assumptions with respect to industry performance, business and economic conditions, and other matters, many of which are beyond the control of Mercantile and First Mercantile Bank. Any estimates contained in SAMCO's analyses are not necessarily indicative of future results or values, which may be significantly more or less favorable than such estimates. Estimates of values of companies do not purport to be appraisals of such companies or necessarily reflect the prices at which such companies or their securities may actually be sold. 20 In order to determine the fairness of the consideration to be received by Mercantile shareholders pursuant to the merger agreement, SAMCO utilized net asset value, market value and investment value approaches, as explained below. Net Asset Value Method. Net asset value is the value of the net equity of a company, including every kind of property and value. This approach normally assumes liquidation on the date of appraisal with recognition of securities gains or losses, real estate appreciation or depreciation and any adjustments to the loan loss reserve, discounts to the loan portfolio or changes in the net value of other assets. As such, it is not the best approach to use when valuing a going concern, because it is based on historical costs and varying accounting methods. Even if the assets and liabilities are adjusted to reflect prevailing prices and yields (which is often of limited accuracy because readily available data is often lacking), it still results in a liquidation value for the concern. Furthermore, since this method does not take into account the values attributable to the going concern such as the interrelationship among Mercantile's assets, liabilities, customer relations, market presence, image and reputation, and staff expertise and depth, little or no weight is given to the net asset value method of valuation. Market Value Method. Market value is defined as the price at which property would change hands between a willing seller and a willing buyer when both parties have the same information and neither party is acting under compulsion. This definition of value produces a result that could be achieved if the property were to be sold in an arm's-length transaction. The market value method is frequently used to determine the price of a smaller block of stock when both the quantity and the quality of the "comparable" data are deemed sufficient. However, the relative thinness of the specific market for the Mercantile common stock being appraised may result in the need to review alternative markets for comparative pricing purposes. The "hypothetical" fair value for the shares of a small bank holding company with a thin market for its stock is normally determined by creating a universe of regional or state publicly-traded bank stock values and related financial traits within an appropriate geography, then developing pricing statistics for the appraised bank from the pricing characteristics of the regional or state publicly-traded banking organizations. These pricing characteristics form the statistical basis for developing indications of value based on applying the statistics derived from the sample universe to the relevant financial values of the subject company being valued. The statistical values used in this valuation study were: . price to book value; . price to earnings, and . price to assets. SAMCO's market value analysis, however, reflects the fact that: . no company or transaction used in the comparison is identical to BancGroup, Mercantile or the merger; . the stocks of publicly-held banking organizations in Texas are far more liquid than the Mercantile common stock; . certain nonfinancial characteristics for the regional publicly-traded Texas banking organizations vary substantially from Mercantile; and . the average financial performance of publicly-held Texas banking organizations vary, sometimes significantly from those of Mercantile. Therefore, SAMCO chose to compare Mercantile to those acquired in merger and acquisition transactions in Texas between January 1999 and December 2001 involving banks or bank holding companies with total assets between $100 million and $500 million. This comparison yielded pricing multiples that were then applied to Mercantile, resulting in a range of per share values from $26.42 per share to $51.50 per share. Additionally, SAMCO took into consideration Mercantile's recent acquisition of TownBank as well as its growth over the past three years, and recognized that the value of a share of the Mercantile common stock would fall into the higher range of the per share values calculated. 21 Investment Value Method. Investment value is sometimes referred to as the income value or the earnings value. The investment value is frequently defined as an estimate of the present value of future benefits. Another popular investment value method is to determine the level of the current annual benefits and then capitalize one or more of the benefit types using an appropriate capitalization rate such as an earnings or dividend yield. SAMCO used Mercantile's historical earnings over the past four years to arrive at a normalized earnings figure. The weighted average of historical economic earnings is most appropriately used for calculating future earnings when there appears to be a general pattern that may be extrapolated into the future, giving the highest weighting to the most recent year, and the lowest weighting to the most distant year. Using a net present value discount rate of between 12% and 14% as an acceptable discount rate, and assuming a growth rate of 10%, SAMCO calculated a range of value of between $8.00 and $12.00 per share of Mercantile common stock. Additionally, SAMCO developed earnings projections for Mercantile for the years 2001 through 2005. The financial forecasts and projections of Mercantile prepared by SAMCO were based on discussions with senior management of Mercantile, projections provided by Mercantile, and SAMCO's own assessment of general economic, market and financial conditions. All such information was reviewed with management of Mercantile. The forecasts, and projections prepared by SAMCO were based on numerous variables and assumptions which are inherently uncertain, including, without limitation, factors related to general economic and market conditions. Accordingly, actual results could vary significantly, from those set forth in such forecasts and projections. Capitalization of Dividends Method. Another method of valuing a block of stock is the capitalization of dividends approach. Because closely-held banking organizations, such as Mercantile, typically pay no dividends or lower dividends per dollar of earnings capacities than do publicly-held banking organizations, SAMCO determined that such an analysis was of limited usefulness. While utilizing each approach discussed above to value Mercantile, SAMCO gave greater consideration to the Market Value method, which supports the financial fairness of the exchange ratio. Therefore, SAMCO is of the opinion that the exchange ratio is fair, from a financial point of view, to the Mercantile shareholders. Each Mercantile shareholder is encouraged to read the fairness opinion in its entirety. The full text of the fairness opinion is attached as Appendix C to this proxy statement-prospectus. As mentioned above, the evaluation shall be made available for inspection and copying by any interested Mercantile shareholder, or such shareholder's authorized representative, at the principal offices of Mercantile during Mercantile's regular business hours. A copy of the evaluation may also be transmitted by Mercantile to any interested Mercantile shareholder, or such shareholder's representative, upon written request and at the expense of such shareholder. Mercantile shall be entitled to receive prior written evidence of such shareholder's grant of authority to Mercantile shareholder's representative to either examine or receive copies of the evaluation. Prior to granting access to the evaluation, Mercantile shall, in its sole discretion, also be entitled to require such interested shareholder or such shareholder's representative to enter into a confidentiality agreement, in form and substance satisfactory to Mercantile. Recommendation of the Board of Directors of Mercantile The Board of Directors of Mercantile has determined that the merger agreement is in the best interest of Mercantile shareholders. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF MERCANTILE VOTE "FOR" PROPOSAL 1: APPROVAL OF THE MERGER AGREEMENT. BancGroup's Reasons for the Merger The board of directors of BancGroup has unanimously approved the merger and the merger agreement. The merger will allow BancGroup to expand its banking operations in the Dallas market area. BancGroup currently operates a commercial bank with three branches in Dallas, Texas. The board of directors of BancGroup believes that the combination with Mercantile and First Mercantile Bank is consistent with its current expansion strategy. 22 In approving the merger and the merger agreement, the Board of Directors of BancGroup took into account: . the financial performance and condition of Mercantile and First Mercantile Bank, including its capital and asset quality; . similarities in the philosophies of BancGroup and Mercantile, including Mercantile's commitment to delivering high quality personalized financial services to its customers; and . Mercantile's management's knowledge of, and experience in, the Dallas, Texas market. Interests of Certain Persons in the Merger Certain members of Mercantile's and First Mercantile Bank's management teams and boards of directors may be deemed to have certain interests in the merger in addition to their interest as shareholders of Mercantile generally. Mercantile's board of directors was aware of these interests and considered them, among other matters, in unanimously approving the merger agreement. Assumption of Options. As of the date of this proxy statement-prospectus, Mercantile had outstanding options that entitle the holders thereof to acquire up to 232,000 shares of Mercantile common stock. The merger agreement provides that the Mercantile options, to the extent not exercised prior to the Effective Date, will be assumed by BancGroup on essentially the same terms as were applicable to such options to acquire Mercantile common stock except that the options will thereafter represent the right to acquire BancGroup common stock, the number of shares BancGroup common stock represented by each Mercantile option will equal the number of shares of Mercantile common stock subject to the Mercantile option multiplied by the exchange ratio and the exercise price of each option to acquire BancGroup common stock will be equal to the exercise price for each share of Mercantile common stock subject to such Mercantile option divided by the Exchange Ratio. Alternatively, the merger agreement allows the holders of these Mercantile options to exchange some or all of their Mercantile options for cash or for BancGroup common stock without paying an exercise price. If a holder chooses to participate in the "cash free exchange", then pursuant to the merger agreement he or she will receive an amount of cash or BancGroup common stock equal to the value of such holder's Mercantile options less the exercise price of such options. Additionally, if a Mercantile option holder is an officer of Mercantile and chooses to participate in the "cash free exchange" then that holder will also receive a cash bonus equal to 34% of the value of their Mercantile options exchanged. See "Proposal 1: Approval of the Merger Agreement--Treatment of Mercantile Options." Employees. BancGroup has entered into an employment agreement with Roy J. Salley, the Chief Executive Officer of Mercantile and First Mercantile Bank to be effective upon the completion of the merger. Mr. Salley's employment agreement provides that he will, among other things, act as President and Chief Executive Officer of Colonial Bank's Texas Region, for compensation based upon his current annual salary of $210,000 plus a car allowance of $750 per month and club memberships of up to $10,000 per year. The employment agreement also provides that Mr. Salley will be eligible to receive 10,000 shares of BancGroup common stock in the form of a restricted stock award, an incentive-based bonus of up to $75,000 and options to acquire 25,000 shares of BancGroup common stock. The term of the employment agreement is three years after the Effective Date, which shall automatically be extended to five years after the Effective Date unless either Mr. Salley or BancGroup notifies the other of termination prior to the second anniversary date of the Effective Date. BancGroup may terminate the employment agreement prior to that date by paying Mr. Salley a cash payment equal to the total salary that would otherwise be paid for the remainder of the term of the employment agreement. The employment agreement also provides that Mr. Salley will not compete against BancGroup in Dallas or Travis Counties, Texas or any county contiguous to either such county for certain specific periods of time depending on certain contingencies outlined in the employment agreement. BancGroup has entered into an employment agreement with C. Malcolm Holland, the President of First Mercantile Bank to be effective upon the completion of the merger. Mr. Holland's employment agreement 23 provides that he will, among other things, act as the Chief Credit Officer of Colonial Bank's Texas Region for compensation based upon his current annual salary of $190,000 plus a car allowance of $500 per month and club memberships of up to $5,000 per year. The employment agreement also provides that Mr. Holland will be eligible to receive 5,000 shares of BancGroup common stock in the form of a restricted stock award, an incentive-based cash bonus of up to $50,000 and options to acquire 15,000 shares of BancGroup common stock. The term of the employment agreement is three years after the Effective Date, which shall automatically be extended by an additional two years unless either Mr. Holland or BancGroup notifies the other of termination prior to the second anniversary of the Effective Date. BancGroup may terminate the employment agreement prior to that date by paying Mr. Holland a cash payment equal to the total salary that would otherwise be paid for the remainder of the term of the employment agreement. The employment agreement also provides that Mr. Holland will not compete against BancGroup in Dallas or Travis Counties, Texas or any county contiguous to either such county for certain specific periods of time depending on certain contingencies outlined in the employment agreement. BancGroup has entered into an employment agreement with Michael A. Kowalski, Executive Vice President and Chief Financial Officer of First Mercantile Bank to be effective upon the completion of the merger. Mr. Kowalski's employment agreement provides that he will, among other things, act as an Branch President of Colonial Bank's Mesquite Texas branch for an annual salary of $115,000. The employment agreement also provides that Mr. Kowalski will be eligible to receive options to acquire 5,000 shares of BancGroup common stock. The term of the employment agreement is two years after the Effective Date. BancGroup may terminate the employment agreement prior to that date by paying Mr. Kowalski a cash payment equal to the total salary that would otherwise be paid for the remainder of the term of the employment agreement. The employment agreement also provides that Mr. Kowalski will not compete against BancGroup in Dallas or Travis Counties, Texas or any county contiguous to either such county for certain specific periods of time depending on certain contingencies outlined in the employment agreement. On the Effective Date, all employees of Mercantile will, at BancGroup's discretion, either become employees of BancGroup or its subsidiaries or be entitled to severance benefits in accordance with Colonial Bank's severance policy as of the date of the merger agreement. All employees of Mercantile who become employees of BancGroup or its subsidiaries on the Effective Date will be entitled, to the extent permitted by applicable law, to participate in all benefit plans of BancGroup to the same extent as BancGroup's employees. Affiliate Agreements. Mercantile's directors and certain executive officers have entered into affiliate agreements with BancGroup regarding various issues associated with the merger. These agreements provide that the director or executive officer would, among other things: . agree to vote his or her shares for the merger; . not distribute BancGroup common stock issued in connection with the merger except in accordance with certain rules of the SEC; . support the business of Colonial Bank after the merger; and . not sell, transfer or otherwise encumber 25% of the BancGroup common stock such person receives in connection with the merger for two years following the merger. Additionally, Mercantile directors who are not also employees of Mercantile agreed generally not to compete with Colonial Bank for the longer of four years following the merger or two years after such person ceases to be a regional or local director for Colonial Bank and will be entitled to receive a cash payment of $125,000 for this non-compete agreement. Cash Bonus to Chief Executive Officer. Prior to the signing of the merger agreement with BancGroup, Mercantile's board of directors agreed to pay Roy J. Salley a cash bonus if certain conditions were satisfied. These conditions included the successful sale of Mercantile at a price of greater than $40.00 per share. Pursuant to that agreement, Mr. Salley will receive at the closing of the merger a cash bonus of 0.75% of the merger 24 consideration paid to Mercantile shareholders. Although the exact amount of the cash bonus to Mr. Salley cannot be known until the Market Value of BancGroup common stock is established, if the Market Value of BancGroup common stock as of the Effective Date is $15.00 or greater per share, and the Mercantile shareholders approve the 280G payments then Mr. Salley will receive a cash bonus of approximately $523,439. In the event the Mercantile shareholders do not approve the 280G payments, Mr. Salley will still receive a portion of the cash bonus. See "Proposal 2: 280G Payments" for a more thorough discussion of the 280G payments to Mr. Salley. Indemnification. Under the merger agreement, BancGroup has agreed for a period of three years to indemnify the directors and executive officers of Mercantile against certain claims and liabilities arising out of or pertaining to matters existing or occurring at or prior to the Effective Date, to the extent that Mercantile would have been authorized under Texas law, or under its Articles of Incorporation or Bylaws, to indemnify such persons. BancGroup has also agreed to use commercially reasonable efforts to maintain in effect for a period of three years following the merger the current policies of directors' and officers' liability insurance currently maintained by Mercantile with respect to claims arising from facts or events that occurred before the merger became effective. Conversion of Mercantile Common Stock On the Effective Date, each share of Mercantile common stock outstanding and held by the Mercantile shareholders, except shares as to which dissenters' rights are perfected, will be converted by operation of law and without any action by any holder thereof into 3.4808 shares of BancGroup common stock, provided that the Market Value for BancGroup common stock is not less than $11.00 per share nor greater than $15.00 per share. . If the Market Value is less than $11.00, then each share of Mercantile common stock outstanding at the Effective Date shall be converted into the number of shares of BancGroup common stock that shall equal $38.29 divided by the Market Value of BancGroup common stock. . If the Market Value is greater than $15.00, then each share of Mercantile common stock shall be converted into such number of shares of BancGroup common stock that shall equal $52.21 divided by the Market Value of BancGroup common stock. The Market Value shall be the average of the closing prices of the BancGroup common stock as reported by the NYSE on each of the ten consecutive trading days ending on the trading day five trading days immediately preceding the Effective Date. The appropriate ratio that is used to calculate the merger consideration based upon the Market Value as set forth above is referred to as the "exchange ratio." Accordingly, based upon the 1,336,752 shares of Mercantile common stock outstanding and 232,000 stock options outstanding as of the date of this proxy statement-prospectus, and assuming that the Market Value of BancGroup common stock is not less than $11.00 nor more than $15.00, the maximum number of shares of BancGroup common stock that may be issued in the merger will be 5,460,511 (which assumes all stock options of mercantile will be converted into common stock). The number of shares of BancGroup common stock to be issued in the merger will increase proportionally with each share of Mercantile common stock issued pursuant to the exercise, before the Effective Date, of the Mercantile Options. See "Proposal 1: Approval of the Merger Agreement--Interests of Certain Persons in the Merger" and "Proposal 1: Approval of the Merger Agreement--Treatment of Mercantile Options." No fractional shares of BancGroup common stock will be issued in connection with the merger. Each shareholder of Mercantile otherwise entitled to receive a fractional share of BancGroup common stock will receive instead a cash payment (without interest) equal to such fractional interest multiplied by the Market Value. 25 The merger agreement provides that if it is announced between the date of the merger agreement and the Effective Date: . by any person that such person is or has commenced a tender or exchange offer to acquire in excess of 50% of the outstanding shares of BancGroup common stock, or . by BancGroup that it has entered into a letter of intent or an agreement for the acquisition of BancGroup by another person or that BancGroup shall be merged with a person in a transaction in which BancGroup is not the surviving corporation, or a transaction in which BancGroup's current shareholders would own less than 50% of the resulting corporation, then each outstanding share of Mercantile common stock will be converted into 3.4808 shares of BancGroup common stock without reference to the Market Value of BancGroup common stock. As of January 23, 2002, the closing price of BancGroup common stock was $14.57. If, upon the Effective Date, the Market Value is equal to $14.57, then each share of Mercantile common stock will be converted into 3.4808 shares of BancGroup common stock. As a result, a shareholder of Mercantile who owns 500 shares of Mercantile common stock would be entitled to receive 1,740 shares of BancGroup common stock (500 multiplied by 3.4808, rounded down to the nearest whole number) and $5.83 in cash (0.4 multiplied by $14.57) in lieu of a fractional share of BancGroup common stock. Assuming that the Market Value is either greater than $15.00 or less than $11.00, as the Market Value of the BancGroup common stock rises above $15.00 per share, the number of shares of BancGroup common stock to be issued in the merger will decrease, and as the Market Value falls below $11.00 per share, the number of such shares to be issued will increase. The closing sales price on the NYSE of the BancGroup common stock on January 23, 2002 was $14.57 per share. Mercantile shareholders are advised to obtain current market quotations for BancGroup common stock under the symbol "CNB" on the NYSE. The Market Value of the BancGroup common stock at the Effective Date may be higher or lower than the market price of BancGroup common stock as of the record date or at the time of the special meeting. The merger agreement provides that if, prior to the Effective Date, BancGroup common stock is changed into a different number of shares or a different class of shares by reason of any recapitalization or reclassification, stock dividend, combination, stock split, or reverse stock split of the BancGroup common stock, an appropriate and proportionate adjustment will be made in the number of shares of BancGroup common stock into which the Mercantile common stock will be converted in the merger. Surrender of Mercantile Common Stock Certificates On the Effective Date and subject to the conditions described at "Conditions to Consummation of the Merger," Mercantile shareholders, except those shareholders who perfect dissenters' rights under applicable law, will automatically, and without further action by such shareholders or by BancGroup, become owners of BancGroup common stock, as described in the merger agreement. Outstanding certificates representing shares of the Mercantile common stock will, after the close of the merger, represent shares of BancGroup common stock. Thereafter, upon surrender of the certificates formerly representing shares of Mercantile common stock, the holders will be entitled to receive certificates for the BancGroup common stock. Dividends on the shares of BancGroup common stock will accumulate without interest and will not be distributed to any former shareholder of Mercantile unless and until such shareholder surrenders for cancellation his certificate for Mercantile common stock. SunTrust Bank, Atlanta, Georgia, transfer agent for BancGroup common stock, will act as the Exchange Agent with respect to the shares of Mercantile common stock surrendered in connection with the merger. The Exchange Agent will mail a detailed explanation of these arrangements to Mercantile shareholders promptly following the Effective Date. Stock certificates should not be sent to the exchange agent until such notice is received. 26 Treatment of Mercantile Options Assumption of Options. As of the date of this proxy statement-prospectus, Mercantile had granted options, which entitle the holders thereof to acquire up to 232,000 shares of Mercantile common stock. The Mercantile options are issuable pursuant to the Mercantile Bancorp, Inc. Amended and Restated Stock Option Plan, a conversion of a stock option plan originally adopted by First Mercantile Bank on March 8, 1998, and a stock option plan for outside directors originally adopted by Mercantile on April 13, 1999 (collectively, the "Option Plan"). The Option Plan is not qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended, nor subject to the Employee Retirement Income Security Act of 1974. Mercantile options are not transferable except under the laws of descent and distribution. Except for the Mercantile options exercised, exchanged or terminated prior to the Effective Date, BancGroup will assume all Mercantile options outstanding on the Effective Date, and each such option will represent the right to acquire the BancGroup common stock on substantially the same terms applicable to the Mercantile options. The registration statement registering the shares of BancGroup common stock issued pursuant to the merger also registers the shares of BancGroup common stock to be issued upon the exercise of the Mercantile options assumed by BancGroup. The number of shares of BancGroup common stock to be issued pursuant to such options will equal the number of shares of Mercantile common stock subject to such Mercantile options multiplied by the Exchange Ratio, provided that no fraction of shares of BancGroup common stock will be issued, and the number of shares of BancGroup common stock to be issued upon the exercise of Mercantile options, if a fractional share exists, will equal the number of whole shares obtained by rounding to the nearest whole number, giving account to such fraction, or else such fractional interest shall be paid in cash, based upon the Market Value. For a description of how Market Value is calculated see "Proposal 1: Approval of the Merger Agreement--Conversion of Mercantile Common Stock." The exercise price for the acquisition of BancGroup common stock will be the exercise price for each share of Mercantile common stock subject to such options divided by the Exchange Ratio, adjusted appropriately for any rounding to whole shares that may be done. In lieu of the exercise procedure set forth in the previous paragraph, a holder of outstanding Mercantile options may, no later that five days prior to the Effective Date, provide written notice to Mercantile that he or she wishes to exchange his or her Mercantile options, as of the Effective Date, and, to receive an amount of BancGroup common stock or cash. If the holder of Mercantile options elects to receive cash by providing such notice, the amount of cash to be received shall be the difference between the number obtained by multiplying the number of shares of Mercantile common stock issuable pursuant to his or her Mercantile options times the Exchange Ratio times Market Value less the number obtained by multiplying the number of shares of Mercantile common stock issuable pursuant to his or her Mercantile options times the exercise price per share determined pursuant to the Option Plan. The difference is referred to herein as the "Option Consideration". If the holder of Mercantile options elects to receive BancGroup common stock in lieu of cash, the Option Consideration shall be divided by Market Value to determine the number of shares of BancGroup common stock to be received. In the event that the exercise prices of all Mercantile options are not the same, the Option Consideration shall be determined for each series of options and the number of shares of BancGroup common stock issued shall be totaled to obtain the aggregate number of shares to be received by that holder of such Mercantile options. No fractional shares shall be issued and fractions shall be paid in cash at the Market Value. If an officer of Mercantile elects to participate in the cash free exchange of his Mercantile options by giving notice five days prior to the Effective Date, he shall also receive a cash bonus equal to Option Consideration multiplied by 0.34 less any consideration due such Mercantile employee under any "Tax Gross Up Bonus" or any other bonus related in any way to the exercise of Mercantile options. If less than all such options are exchanged, the bonus shall be reduced pro rata for those options not exchanged. Purpose of the Option Plan. The purpose of the Option Plan is to provide an incentive for key employees and directors of Mercantile to remain in the service of Mercantile, to extend to them the opportunity to acquire a proprietary interest in Mercantile so that they will apply their best efforts for the benefit of Mercantile and its affiliates, and to aid Mercantile and its affiliates in attracting and retaining key personnel. BancGroup believes 27 that its assumption of the Mercantile options will be consistent with this purpose. No further options will be granted under the Option Plan after the merger. A total of 18 persons currently hold Mercantile options that represent the right to acquire 232,000 shares of Mercantile common stock. Tax Consequences. Mercantile options issued and held under the Option Plan by employees are not intended to qualify as "incentive stock options," under, and to the extent provided in, Section 422 of the Internal Revenue Code of 1986, as amended. Therefore, the difference between the option exercise price and the fair market value of the stock on the date of exercise will be taxed at ordinary income tax rates. The gain equal to the increase in the fair market value of the stock after the date, of exercise of the option will generally be taxed as capital gain. The foregoing statements concerning federal income tax treatment are necessarily general and may not apply in a particular instance. Option holders should contact their own professional tax advisors for advice concerning their particular tax situation and any changes in the tax law since the date of this proxy statement-prospectus. Exercise of Options. After the merger, all Mercantile options will be exercisable in accordance with their terms and may be exercised by the holder by giving written notice to BancGroup on a form provided by BancGroup and by paying to BancGroup in cash the exercise price of the shares to be acquired under the option. Payment may be made to BancGroup by cash, check, bank draft, or money order. The period during which an option may be exercised is stated in the agreement respecting each grant of options but in no case may be more than ten years from the date the option is granted. The optionee must be in the continuous employ of Mercantile or BancGroup from the date of grant through the date of exercise, except as stated below. Termination of Employment. If an employee is terminated for cause, the option will also terminate as of the date of termination of employee's employment. Otherwise, the Option will terminate three months following the termination of the employee's employment without cause, or one year following the termination of employment as a result of the employee's death, disability or legal incapacity. "Cause" is defined in the Option Plan as the termination of the employee's employment for "cause" under such individual's employment agreement or, in the absence of such agreement, because of the gross misconduct, drug dependence, gross neglect or incompetent performance of assigned duties, proven dishonesty or commission of a felony on the part of such individual which, in the Board's sole discretion renders such individual unable to properly and effectively provide services to, or effectively act as a represent of, Mercantile. Administration. The Option Plan is administered by the Board of Directors of Mercantile. Other Matters. It is not anticipated that BancGroup will make any reports to option holders regarding the amount or status of Mercantile options held. Option holders may obtain such information from BancGroup at the address given above on page of this proxy statement-prospectus. The shares subject to options will be issued by BancGroup from authorized but unissued shares of BancGroup common stock, including treasury shares or from shares purchased by BancGroup on the open market. Certain Federal Income Tax Consequences The merger is intended to qualify as a "reorganization" for federal income tax purposes under Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the "Code"). The obligation of each of Mercantile and BancGroup to consummate the merger is conditioned on the receipt of an opinion from PricewaterhouseCoopers LLP, BancGroup's independent public accountant, to the effect that the merger will constitute such a reorganization. BancGroup and Mercantile have received this opinion. In delivering its opinion, PricewaterhouseCoopers LLP received and relied upon certain representations contained in certificates of 28 officers of BancGroup and Mercantile and certain other information, data, documentation and other materials as it deemed necessary. The tax opinion is based upon customary assumptions contained therein. Neither Mercantile nor BancGroup intends to seek a ruling from the IRS as to the federal income tax consequences of the merger. Mercantile shareholders should be aware that the opinion will not be binding on the IRS or the courts. Mercantile shareholders also should be aware that some of the tax consequences of the merger are governed by provisions of the Code as to which there are no final regulations and little or no judicial or administrative guidance. There can be no assurance that future legislation, administrative rulings, or court decisions will not adversely affect the accuracy of the statements contained herein. The tax opinion states that, provided the assumptions stated therein are satisfied, the merger will constitute a reorganization as defined in Section 368(a) of the Code, and the following federal income tax consequences will result to Mercantile shareholders who exchange their shares of Mercantile common stock for shares of BancGroup common stock: . No gain or loss will be recognized by Mercantile shareholders on the exchange of shares of Mercantile common stock for shares of BancGroup common stock; . The aggregate basis of BancGroup common stock received by each Mercantile shareholder (including any fractional shares of BancGroup common stock deemed received, but not actually received), will be the same as the aggregate tax basis of the shares of Mercantile common stock surrendered in exchange therefor; . The holding period of the shares of BancGroup common stock received by each Mercantile shareholder will include the period during which the shares of Mercantile common stock exchanged therefor were held, provided that the shares of Mercantile common stock were a capital asset in the holder's hands as of the Effective Date; . Cash payments received by each Mercantile shareholder in lieu of a fractional share of BancGroup common stock will be treated for federal income tax purposes as if the fractional share had been issued in the exchange and then redeemed by BancGroup. Gain or loss will be recognized on the redemption of the fractional share and generally will be capital gain or loss if the Mercantile common stock is a capital asset in the hands of the holder; . No gain or loss will be recognized by Mercantile upon the transfer of its assets and liabilities to BancGroup. No gain or loss will be recognized by BancGroup upon the receipt of the assets and liabilities of Mercantile; . The basis of the assets of Mercantile acquired by BancGroup will be the same as the basis of the assets in the hands of Mercantile immediately prior to the merger; . The holding period of the assets of Mercantile in the hands of BancGroup will include the period during which such assets were held by Mercantile; . No gain or loss will be recognized by Mercantile option holders on the assumption and conversion of Mercantile options into options to acquire BancGroup common stock; and . A Mercantile shareholder who dissents and receives only cash pursuant to dissenter's rights will recognize gain or loss. Such gain or loss will, in general, be treated as capital gain or loss, measured by the difference between the amount of cash received and the tax basis of the shares of Mercantile common stock converted, if the shares of Mercantile common stock were held as capital assets. However, a Mercantile shareholder who receives only cash may need to consider the effects of Section 302 and 318 of the Code in determining the federal income tax consequences of the transaction. None of the currently outstanding options to purchase Mercantile common stock are qualified as "incentive" stock options. Therefore, holders of such options will recognize taxable income if and when they exercise such 29 options equal to the fair market value of the stock subject to the option over the exercise price at the date of exercise. Mercantile (or BancGroup if such options are exercised after the completion of the merger) would be entitled to a tax deduction for the same value. If a Mercantile option holder chooses to exchange his or her options for cash or for BancGroup common stock, then such holder will recognize taxable income for the value of such cash or stock and taxable income for the cash bonus that will also be paid to such a holder. See "Proposal 1: Approval of the Merger Agreement--Treatment of Mercantile Options." Each Mercantile shareholder will be required to report on such shareholder's federal income tax return for the fiscal year of such shareholder in which the merger occurs that such shareholder has received BancGroup common stock in a reorganization. THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO THE SHAREHOLDERS OF MERCANTILE, TO MERCANTILE AND TO BANCGROUP AND DOES NOT PURPORT TO BE A COMPLETE DESCRIPTION OF ALL POTENTIAL TAX EFFECTS OF THE MERGER. THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE RELEVANT TO A PARTICULAR SHAREHOLDER SUBJECT TO SPECIAL TREATMENT UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES, BANKS, INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS, NON-UNITED STATES PERSONS, SHAREHOLDERS WHO DO NOT HOLD THEIR SHARES OF MERCANTILE COMMON STOCK AS "CAPITAL ASSETS" WITHIN THE MEANING OF SECTION 1221 OF THE CODE, NOR ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION; THE DISCUSSION IS BASED UPON THE CODE, TREASURY REGULATIONS THEREUNDER AND ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE HEREOF. ALL OF THE FOREGOING IS SUBJECT TO CHANGE, AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING VALIDITY OF THIS DISCUSSION. MERCANTILE SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE MERGER TO THEM. Change in Shareholder Rights If the merger is consummated, the shareholders of Mercantile, a Texas corporation, will become shareholders of BancGroup, a Delaware business corporation. For a discussion of the differences, if any, in the rights, preferences, and privileges attaching to Mercantile common stock as compared with BancGroup common stock, see "Comparative Rights of Stockholders." Conditions to Consummation of the Merger The parties' respective obligations to consummate the merger are subject to the satisfaction (or waiver, to the extent permitted by law) of various conditions set forth in the merger agreement. The obligations of Mercantile and BancGroup to consummate the merger are conditioned upon, among other things: . the approval of the merger agreement by the holders of at least two-thirds of the outstanding shares of Mercantile common stock; . the notification to, or approval of the merger by, the Board of Governors of the Federal Reserve System; . the absence of pending or threatened litigation with a view to restraining or prohibiting consummation of the merger or to obtain divestiture, rescission or damages in connection with the merger; . the absence of any investigation by any governmental agency which might result in any such proceeding; . consummation of the merger no later than August 31, 2002; 30 . the effectiveness of the registration statement; . the receipt of the opinion regarding certain tax matters from PricewaterhouseCoopers LLP; and . receipt of opinions of counsel regarding certain matters. The obligation of Mercantile to consummate the merger is further subject to several other conditions, including: . the absence of any material adverse change in the financial condition or affairs of BancGroup; . SAMCO shall not have withdrawn as of the Effective Date its opinion attached as Appendix C to this proxy statement-prospectus that the terms of the merger are fair, from a financial point of view, to the shareholders of Mercantile; . the shares of BancGroup common stock to be issued under the merger agreement shall have been approved for listing on the NYSE; and . the accuracy in all material respects of the representations and warranties of BancGroup contained in the merger agreement and the performance by BancGroup of all of its covenants and agreements under the merger agreement. The obligation of BancGroup to consummate the merger is subject to several other conditions, including: . the absence of any material adverse change in the financial condition or affairs of Mercantile; . the number of shares as to which holders of Mercantile common stock exercise dissenters' rights not exceeding 10% of the outstanding shares of Mercantile common stock; and . the accuracy in all material respects of the representations and warranties of Mercantile contained in the merger agreement and the performance by Mercantile of all of its covenants and agreements under the merger agreement. It is anticipated that the foregoing conditions, as well as certain other conditions contained in the merger agreement, such as the receipt of certificates of officers of each party as to compliance with the merger agreement and satisfaction of each party of all representations, warranties and covenants, will either be satisfied or waived by the parties. The merger agreement provides that each of Mercantile and BancGroup may waive all conditions to its respective obligation to consummate the merger, other than the receipt of the requisite approvals of regulatory authorities and approval of the merger agreement by the shareholders of Mercantile. In making any decision regarding a waiver of one or more conditions to consummation of the merger or an amendment of the merger agreement, the boards of directors of Mercantile and BancGroup would be subject to the fiduciary duty standards imposed upon such boards by relevant law that would require such boards to act in the best interests of their respective shareholders. Amendment or Termination of Agreement To the extent permitted by law, the merger agreement may be amended by a subsequent writing signed by each of the parties upon the approval of the boards of directors of each of the parties. However, after approval of the merger agreement by the holders of Mercantile common stock, no amendment affecting the consideration to be received by Mercantile shareholders may be made without the further approval of such shareholders. The merger agreement may be terminated at any time prior to or on the Effective Date, whether before or after approval of the merger agreement by the shareholders of Mercantile, by the mutual consent of the respective boards of directors of Mercantile and BancGroup or by the board of directors of either BancGroup or Mercantile under certain circumstances including, but not limited to: . a material breach which cannot or has not been cured within 30 days of notice of such breach being given by the non-breaching party; 31 . failure to consummate the transactions contemplated under the merger agreement by August 31, 2002, provided that such failure to consummate is not caused by any breach of the merger agreement by the party electing to terminate; and . without further action by either party, upon the execution by Mercantile of a legally binding agreement between Mercantile and any third party with respect to any Acquisition Proposal, provided that BancGroup will have the right to demand payment of liquidated damages. See "--Commitment with Respect to Other Offers." Commitment with Respect to Other Offers Until the earlier of the Effective Date or, subject to certain limitations, the termination of the merger agreement, neither Mercantile nor any of its directors or officers (or any person representing any of the foregoing) may solicit or encourage inquiries or proposals with respect to, furnish any information relating to or participate in any negotiations or discussions concerning, any acquisition or purchase of all or of a substantial portion of the assets of, or of a substantial equity interest in, Mercantile or any business combination involving Mercantile (collectively, an "Acquisition Proposal") other than as contemplated by the merger agreement. Mercantile is required to notify BancGroup immediately if any such inquiries or proposals are received by Mercantile, if any such information is requested from Mercantile, or if any such negotiations or discussions are sought to be initiated with Mercantile. Mercantile is required to instruct its officers, directors, agents or affiliates or their subsidiaries to refrain from doing any of the above. Mercantile may communicate information about an Acquisition Proposal to its shareholders if and to the extent that legal counsel provides a written opinion to Mercantile that it is required to do so in order to comply with its legal obligations. If Mercantile enters into a letter of intent or definitive agreement with respect to such an Acquisition Proposal either before the Effective Date or termination of the merger agreement (subject to certain exceptions) or receives an Acquisition Proposal and consummates a transaction pursuant to it within 24 months of termination of the merger agreement (subject to certain exceptions), then Mercantile will pay BancGroup the sum of $6,000,000 as liquidated damages. Regulatory Approvals An application must be filed with the Federal Reserve pursuant to Section 3 of the Bank Holding Company Act of 1956, as amended (the "BHCA") and the regulations promulgated pursuant thereto for its prior approval of the merger. In addition, notice of the merger must be filed with the Texas Department of Banking (the "Texas Department") pursuant to Texas Finance Code (S) 202.001. Subsequent to the merger, it is anticipated that First Mercantile Bank will be merged with and into Colonial Bank (the "Bank Merger"). Prior to the consummation of the Bank Merger, the approval of the Bank Merger by the Federal Reserve and the Alabama State Banking Department ("Alabama Department") must be obtained, and notice of the Bank Merger must be filed with the Office of the Comptroller of the Currency (the "OCC"). With respect to the Bank Merger, applications were filed with the Federal Reserve and the Alabama Department, and a notification was filed with the OCC, on January 16, 2002. With respect to the merger, an application was filed with the Federal Reserve and a notification was filed with the Texas Department on January 16, 2002. The regulatory approval process is expected to take approximately six weeks from this date. Federal Reserve Approval. Pursuant to Section 3 of the BHCA, and the regulations promulgated pursuant thereto, the approval of the Federal Reserve must be obtained prior to completion of the merger. The Federal Reserve must withhold approval of the merger if it finds that the transaction will result in a monopoly or be in furtherance of any combination or conspiracy to monopolize or attempt to monopolize the business of banking in any part of the United States. In addition, the Federal Reserve may not approve the merger if it finds that the effect thereof may be substantially to lessen competition in any section of the country, or tend to create a monopoly, or would in any other manner be in restraint of trade, unless it finds that the anti-competitive effects of the merger are clearly outweighed by the probable effect of the merger in meeting the convenience and needs of the communities to be served. The Federal Reserve will also take into consideration the financial condition 32 and managerial resources of BancGroup, its subsidiaries, any banks related to BancGroup through common ownership or management, and First Mercantile Bank. Finally, the Federal Reserve will consider the compliance records of BancGroup's subsidiaries under the Community Reinvestment Act. In addition, the Federal Reserve is expressly permitted to approve applications under Section 3 of the BHCA for a bank holding company that is adequately capitalized and adequately managed to acquire control of a bank located in a state other than the home state of such bank holding company (an "Interstate Acquisition"), without regard to whether such transaction is prohibited under the law of any state. However, if the law of the state in which the target bank is located requires the target bank to have been in existence for some minimum period of time, the Federal Reserve is prohibited from approving an application by a bank holding company to acquire such target bank if such target bank does not satisfy this state law requirement, so long as the state law specifying such minimum period of time does not specify a period of more than five years. Also, the Federal Reserve is prohibited from approving an Interstate Acquisition if the acquiring bank holding company controls, or upon consummation of the acquisition, would control, more than 10% of the total amount of deposits of insured depository institutions in the United States. Finally, subject to certain exceptions, the Federal Reserve may not approve an application pertaining to an Interstate Acquisition if, among other things, the bank holding company, upon consummation of the acquisition, would control 30% or more of the total amount of deposits of insured depository institutions in the state where the target bank is located. The BHCA provides for the publication of notice and public comment on the application and authorizes the Federal Reserve to permit interested parties to intervene in the proceedings. If an interested party is permitted to intervene, such intervention could delay the regulatory approvals required for consummation of the merger. Section 11 of the BHCA imposes a waiting period which prohibits the consummation of the merger, in ordinary circumstances, for a period ranging from 15 to 30 days following the Federal Reserve's approval of the merger. During such period, the United States Department of Justice, should it object to the merger for antitrust reasons, may challenge the consummation of the merger. Pursuant to Section 18(c) of the Federal Deposit Insurance Act (the "Bank Merger Act"), the Federal Reserve's prior approval of the Bank Merger must be obtained. The Federal Reserve is prohibited from approving the Bank Merger if it would result in a monopoly or would be in furtherance of any combination or conspiracy to monopolize or to attempt to monopolize the business of banking in any part of the United States. In addition, the Federal Reserve is prohibited from approving the Bank Merger if its effect, in any section of the country, would be substantially to lessen competition, or to tend to create a monopoly, or which in any other manner would be in restraint of trade, unless it finds that the anti-competitive effects of the Bank Merger are clearly outweighed in the public interest by the probable effect of the Bank Merger in meeting the convenience and needs of the community to be served. The Federal Reserve is required to take into consideration the financial and managerial resources and future prospects of the existing and proposed institutions, and the convenience and needs of the community to be served. Finally, the Federal Reserve will consider the compliance records of the applicant bank under the Community Reinvestment Act. In that the Bank Merger constitutes an interstate bank merger, certain additional requirements are applicable to the Bank Merger. For example, the Federal Reserve is prohibited from approving the Bank Merger if the bank resulting from the Bank Merger, including all insured depository institutions which are affiliates of such resulting bank, upon consummation of the transaction, would control more than 10% of the total amount of deposits of insured depository institutions in the United States. The Federal Reserve is also prohibited from approving the Bank Merger if either party to the Bank Merger has a branch in any state in which any other bank involved in the Bank Merger has a branch, and the resulting bank, upon consummation of the Bank Merger, would control 30% or more of the total amount of deposits of insured depository institutions in any such state. Finally, the Federal Reserve may approve the interstate bank merger only if each bank involved in the transaction is adequately capitalized as of the date the application is filed, and the Federal Reserve determines that the resulting bank will continue to be adequately capitalized and adequately managed upon consummation of the Bank Merger. 33 The Bank Merger Act and the Federal Reserve regulations provide for the publication of notice and public comment on the application and authorizes the Federal Reserve to permit interested parties to intervene in the proceedings. If an interested party is permitted to intervene, such intervention could delay the regulatory approvals required for consummation of the Bank Merger. The Bank Merger Act imposes a waiting period which prohibits consummation of the Bank Merger, in ordinary circumstances, for a period ranging from 15 to 30 days following the Federal Reserve's approval of the Bank Merger. During such period, the United States Department of Justice, should it object to the merger for antitrust reasons, may challenge the consummation of the merger. Alabama Department Approval. The Bank Merger must be approved by the Alabama Department pursuant to applicable provisions of the Alabama Banking Code. The Superintendent of the Alabama Department will approve the Bank Merger, if he finds that: . the proposed transaction will not be detrimental to the safety and soundness of the bank resulting from the Bank Merger, . any new officers and directors of the resulting bank are qualified by character, experience, and financial responsibility to direct and manage the resulting bank, and . the proposed Bank Merger is consistent with the convenience and needs of the communities to be served by the resulting bank in the State of Alabama and is otherwise in the public interest. The merger agreement provides that the obligation of each of BancGroup and Mercantile to consummate the merger is conditioned upon the receipt of all necessary regulatory approvals to merge Mercantile with and into BancGroup. The approval of the Bank Merger is not required to consummate the merger. There can be no assurance that the application necessary for BancGroup to consummate the merger with Mercantile will be approved, and, if such approval is received, that such approval will not be conditioned upon terms and conditions that would cause the parties to abandon the merger. Any approval received from bank regulatory agencies reflects only their view that the merger does not contravene applicable competitive standards imposed by law, and that the merger is consistent with regulatory policies relating to safety and soundness. THE APPROVAL OF THE BANK REGULATORY AGENCIES IS NOT AN ENDORSEMENT OR RECOMMENDATION OF THE MERGER. BancGroup is not aware of any governmental approvals or actions that may be required for consummation of the merger except for the prior approval of the Federal Reserve and notification to the Texas Department described above. Should any such approval or action be required, it is presently contemplated that such approval or action would be sought. Conduct of Business Pending the Merger The merger agreement contains certain restrictions on the conduct of the business of Mercantile pending consummation of the merger. The merger agreement prohibits Mercantile from taking, without the prior written consent of BancGroup, any of the following actions, prior to the Effective Date, subject to certain limited exceptions previously agreed to by BancGroup and Mercantile: . Issuing, delivering or agreeing to issue or deliver any stock, bonds or other corporate securities (whether authorized and unissued or held in the treasury), except shares of Mercantile common stock issued upon the exercise of Mercantile options; . Borrowing or agreeing to borrow any funds or incurring or becoming subject to, any liability (absolute or contingent) except borrowings, obligations and liabilities incurred in the ordinary course of business and consistent with past practice; . Paying any material obligation or liability (absolute or contingent) other than current liabilities reflected in or shown on the most recent balance sheet and current liabilities incurred since that date in the ordinary course of business and consistent with past practice; 34 . Declaring or making or agreeing to declare or make, any payment of dividends or distributions of any assets of any kind whatsoever to shareholders, or purchasing or redeeming or agreeing to purchase or redeem, any of its outstanding securities except if the merger is not consummated prior to the record date for BancGroup's second quarter dividend (which is usually declared in July), Mercantile may pay to its shareholders a cash dividend equal to what they would have received if the merger had already been consummated, however, in no event shall Mercantile shareholders be entitled to a dividend from both Mercantile and BancGroup in the quarter that the merger is consummated; . Except in the ordinary course of business, selling or transferring or agreeing to sell or transfer, any of its assets, property or rights or canceling, or agreeing to cancel, any debts or claims; . Except in the ordinary course of business, entering or agreeing to enter into any agreement or arrangement granting any preferential rights to purchase any of its assets, property or rights or requiring the consent of any party to the transfer and assignment of any of its assets, property or rights; . Waiving any rights of value which in the aggregate are material; . Except in the ordinary course of business, making or permitting any amendment or termination of any contract, agreement or license to which it is a party if such amendment or termination is material considering its business as a whole; . Except in accordance with past practice and set forth in schedules to the merger agreement, making any accrual or arrangement for or payment of bonuses or special compensation of any kind or any severance or termination pay to any present or former officer or employee; . Except in accordance with past practice, increasing the rate of compensation payable to or to become payable to any of its officers or employees or making any material increase in any profit-sharing, bonus, deferred compensation, savings, insurance, pension, retirement or other employee benefit plan, payment or arrangement made to, for or with any of its officers or employees; . Failing to operate its business in the ordinary course so as to preserve its business intact and to preserve the goodwill of its customers and others with whom it has business relations; and . Entering into any other material transaction other than in the ordinary course of business. The merger agreement provides that prior to the Effective Date, no director or officer of Mercantile or any of its subsidiaries shall, directly or indirectly, own, manage, operate, join, control, be employed by or participate in the ownership, proposed ownership, management, operation or control of or be connected in any manner with, any business, corporation or partnership which is competitive to the business of Mercantile or its subsidiaries. The merger agreement also provides that (i) at the request of BancGroup, Mercantile will consult with BancGroup and advise BancGroup in advance of all loan requests outside the ordinary course of business or in excess of $500,000 that are not single-family residential loan requests; and (ii) Mercantile will consult with BancGroup respecting business issues that Mercantile believes should be brought to the attention of BancGroup. The merger agreement also provides that Mercantile, or any agent of Mercantile, will not solicit or negotiate with any other entity with the purpose of allowing Mercantile, or substantially all of its assets, to be purchased by an entity other than BancGroup. Likewise, Mercantile has agreed not to enter into any contract that would result in the sale of Mercantile, or substantially all of its assets, to an entity other than BancGroup. Under most circumstances, if Mercantile is acquired by an entity other than BancGroup within 24 months of the termination of the merger agreement (other than if such termination is caused by BancGroup's breach of the merger agreement), then Mercantile, or the acquiring entity, will be obligated to pay the principal sum of $6,000,000 to BancGroup. 35 Indemnification BancGroup has agreed to indemnify for three years present and former directors and officers of Mercantile and the Bank against liabilities arising out of actions or omissions occurring at or prior to the Effective Date to the maximum extent provided in the Texas Business Corporation Act, or the TBCA, and Mercantile's Articles of Incorporation and Bylaws. BancGroup has also agreed to use commercially reasonable efforts to maintain in effect for a period of three years following the merger the current policies of directors' and officers' liability insurance currently maintained by Mercantile with respect to claims arising from facts or events that occurred before the merger became effective. Rights of Dissenting Shareholders Shareholders of Mercantile as of the record date may exercise dissenters' rights in connection with the merger by complying with Articles 5.11, 5.12 and 5.13 of the TBCA. Consummation of the merger is subject to, among other things, the holders of no more than 10% of the outstanding Mercantile common stock electing to exercise their dissenters' rights. By exercising dissenters' rights, you will be entitled to receive, if the merger is consummated, the "fair value" of the shares of Mercantile common stock that you owned as of the day immediately prior to the date of the special meeting. This value may differ from the value of the consideration that you would otherwise receive in the merger. The following is a summary of the statutory procedures that you must follow in the event you elect to exercise your dissenters' rights under the TBCA. This summary is not complete and is qualified in its entirety by reference to Articles 5.11, 5.12 and 5.13 of the TBCA, the text of which is set forth in full in Appendix B to this proxy statement-prospectus. How to exercise and perfect your right to dissent. In order to be eligible to exercise your right to dissent to the merger and to receive, upon compliance with the statutory requirements summarized below, the fair value of your shares of Mercantile common stock as of the day immediately preceding the special meeting, excluding any appreciation or depreciation in anticipation of the merger: . you must, prior to the special meeting, provide Any written objection with notice of intent to exercise Mercantile with a written objection to the the right of dissent should be addressed as follows: merger that states that you intend to exercise Mercantile Bancorp, Inc. your right to dissent if the merger is 8144 Walnut Hill Lane, Suite 180 consummated and that provides an address to Dallas, Texas, 75231 which a notice about the outcome of the vote Attention: Corporate Secretary on the merger may be sent; and . you must not vote your shares of Mercantile You should sign every communication common stock in favor of the merger agreement In order to exercise properly dissenter's rights, you must refrain from voting by proxy or in person in favor of the merger agreement. A shareholder who executes and returns an unmarked proxy will have his or her shares voted "for" the merger agreement and, as a consequence thereof, such shareholder will be foreclosed from exercising rights as a dissenting shareholder. Your demand for payment. If you comply with the two items described above and the merger is completed, BancGroup, as the surviving corporation, will within 10 days of the completion of the merger deliver or mail to all holders of Mercantile common stock who satisfied the foregoing requirements a written notice that the merger has been completed. You must, within 10 days of the date the notice was sent to you by BancGroup, send a written demand to BancGroup for payment of the fair value of your shares of Mercantile common stock. Such written demand must state the number and class of the shares that you owned as of the record date and your estimate of the fair value of the shares. The fair value of your shares of Mercantile common stock will be the value of the shares on the day immediately preceding the special meeting, excluding any appreciation or 36 depreciation in anticipation of the merger. If you should fail to make such a demand within the ten-day period, you will lose the right to dissent and will be bound by the terms of the merger agreement. In order to preserve dissenters' rights, you must also submit your stock certificates to BancGroup within 20 days of making a demand for payment for notation thereon that such demand has been made. The failure to do so shall, at BancGroup's option, terminate your rights to dissent and appraisal unless a court of competent jurisdiction for good and sufficient cause shown shall direct otherwise. Any notice addressed to BancGroup must be addressed to: Office of the Senior Counsel The Colonial BancGroup, Inc.

If you and BancGroup have not agreed upon the fair value of your shares of Mercantile common stock within the 60-day period immediately subsequent to the completion of the merger, then either you or BancGroup may, within 60 days of the expiration of the 60 days after the effective date of the merger, file a petition in any court of competent jurisdiction in Dallas County, Texas, asking for a finding and determination of the fair value of the shares. If filed by a shareholder, service of the petition shall be had upon BancGroup as the surviving corporation and BancGroup must within 10 days after service file with the clerk of the court a list with the names and addresses of all shareholders who have demanded payment and not reached agreement as to the fair value. If filed by BancGroup, the petition must be accompanied by such a list. The clerk of the court shall give notice to BancGroup and all shareholders named on the list of the time and place fixed for the hearing of the petition. After the hearing of the petition, the court shall determine the stockholders who have complied with the statutory requirements and have become entitled to the valuation of and payment for their shares, and the court shall appoint one or more qualified appraisers to determine the fair value. The appraisers may examine the books and records of Mercantile and shall afford the interested parties a reasonable opportunity to submit pertinent evidence. The appraisers are to make a determination of the fair value upon such examination as they deem proper. The appraisers shall file a report of the value in the office of the clerk of the court, notice of which shall be given to the parties in interest. The parties in interest may submit exceptions to the report, which will be heard before the court upon the law and the facts. The court shall adjudge the fair value of the shares of the shareholders entitled to payment for their shares and shall direct the payment 37 thereof by BancGroup as the surviving corporation, together with interest which shall begin to accrue 91 days after the effective date of the merger.

Upon BancGroup's payment of the judgment, you shall cease to have any interest in the shares. The court shall allow the appraisers a reasonable fee as court costs, and all court costs shall be allotted between the parties in the manner that the court determines to be fair and equitable, with the respective parties to bear their own attorneys' fees. Any shareholder who has demanded payment for such holder's shares may withdraw such demand at any time before payment or before any petition has been filed for valuation by the court. A demand may not be withdrawn after payment or, unless BancGroup consents, after such a petition has been filed in court. After a demand has been withdrawn, the stockholder and all persons claiming under the shareholder shall be conclusively presumed to have approved the Agreement and shall be bound by its terms. Federal income tax consequences. See "Proposal 1: Approval of the Merger Agreement--Certain Federal Income Tax Consequences," beginning on page for a discussion on how the federal income tax consequences of your action will change if you elect to dissent from the merger. Resale of BancGroup Common Stock Issued in the Merger The shares of BancGroup common stock to be issued to Mercantile shareholders pursuant to the merger agreement, including any shares to be issued pursuant to Mercantile options, have been registered under the Securities Act of 1933 (the "Securities Act"). As a result, shareholders of Mercantile who are not "affiliates" of Mercantile may resell, without restriction, all shares of BancGroup common stock which they receive in connection with the merger. Under the Securities Act, only affiliates of Mercantile are subject to restrictions on the resale of the BancGroup common stock which they receive in the merger. The definition of "affiliate" is complex and depends on the specific facts of each individual, but generally includes directors, executive officers, 10% shareholders and other persons with the power to direct management policies of the corporation in question. The BancGroup common stock received by affiliates of Mercantile who do not also become affiliates of BancGroup after the consummation of the merger may not be sold except pursuant to an effective registration statement under the Securities Act covering such shares or in compliance with Rule 145 under the Securities Act or another applicable exemption from the registration requirements of the Securities Act. Generally, Rule 145 permits BancGroup common stock held by such shareholders to be sold in accordance with certain provisions of Rule 144 under the Securities Act. In general, these provisions of Rule 144 permit a person to sell on the open market in brokers or certain other transactions within any three-month period a number of shares that does not exceed the greater of 1% of the then outstanding shares of BancGroup common stock or the average weekly trading volume in BancGroup common stock reported on the NYSE during the four calendar weeks preceding such sale. Sales under Rule 144 are also subject to the availability of current public information about BancGroup. The restrictions on sales will cease to apply under most circumstances once the former Mercantile affiliate has held the BancGroup common stock for at least one year. BancGroup common stock held by affiliates of Mercantile who become affiliates of BancGroup, if any, will be subject to additional restrictions on the ability of such persons to resell such shares. Mercantile has provided BancGroup with the identity of individuals (primarily officers, directors and principal shareholders) who may be deemed to be affiliates of Mercantile. BancGroup has obtained from those individuals a written undertaking to the effect that the individual agrees not to make a distribution within the meaning of Rule 145 under the Securities Act or to sell, transfer or otherwise dispose of the shares of BancGroup common stock received in the merger except in accordance with the Securities Act. In addition, directors and certain executive officers of Mercantile and First Mercantile Bank have agreed in the affiliate agreements they entered into with BancGroup to certain additional restrictions on resale of the BancGroup common stock issued to them in the merger. For a description of the affiliate agreements, see "Proposal 1: Approval of the Merger Agreement--Interests of Certain Persons in the Merger--Affiliate Agreements" on page . 38 Accounting Treatment BancGroup will account for the merger as a purchase transaction in accordance with generally accepted accounting principles. Under this accounting treatment, and in accordance with Statement of Financial Accounting Standards No. 141, Business Combinations, the purchase price will be assigned to the fair value of the net tangible and intangible assets acquired, with any amounts in excess thereof being assigned to "goodwill." The valuation of intangibles, if any, will be made as of the Effective Date of the merger. In accordance with Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets, qualifying intangibles, such as core deposit intangibles, will be amortized by charges to future earnings over their expected useful lives. Amortization of core deposit intangibles is non-deductible for tax purposes. The remaining goodwill will be capitalized and evaluated for impairment on an annual basis, or if circumstances arise in which it is more likely than not the fair value of the related reporting unit has been reduced. If such goodwill were to be deemed impaired, such impairment would be measured and any such amount would be charged against current earnings. Mercantile Trust Preferred Securities In September 2001, MBI Capital Trust I, a special purpose finance subsidiary of Mercantile, issued 800,000 of its floating rate cumulative preferred securities having an aggregate liquidation value of $8,000,000 in a private placement exempt from the registration requirements of the Securities Act. At that time, Mercantile acquired 25,000 of the trust's floating rate cumulative common securities having an aggregate liquidation value of $250,000. The preferred securities and the common securities represent undivided beneficial interests in the assets of the trust, which consist solely of a floating rate subordinated debenture, due September 2031, issued by Mercantile in aggregate principal amount of $8,250,000. The subordinated debenture accrues interest at a floating rate of 125 basis points over the prime rate per annum as published in The Wall Street Journal, and the rate is adjusted quarterly. Through March 31, 2002, the subordinated debenture accrues interest at a rate of 6.00% per annum. Mercantile makes quarterly interest only payments under the subordinated debenture to the trust which, in turn, remits payment to the holders of the preferred securities and the common securities in the form of a quarterly dividend. The principal amount of the subordinated debenture is not due until maturity. Mercantile created the trust for the sole and limited purpose of issuing the preferred securities and the common securities and investing the proceeds from the sale of securities in the subordinated debenture. Mercantile used the proceeds from the sale of the trust preferred securities to finance a portion of the purchase price it paid to acquire TownBank. SAMCO acted as co-placement agent in the trust preferred securities offering. In addition to its obligation to make quarterly payments of interest under the subordinated debenture, Mercantile has, under the preferred securities guarantee agreement, guaranteed to pay directly any amount held by the trust but not distributed to the holders of the preferred securities. Mercantile's obligation under the guarantee would arise only to the extent that the trust receives payments on the subordinated debenture, but does not, for whatever reason, distribute the full amount of the proceeds to the holders of the preferred securities. The merger agreement requires BancGroup to assume Mercantile's obligations related to the trust preferred securities, which includes its obligations under the indenture, including the obligation to make quarterly payments on the subordinated debenture, and the preferred securities guarantee agreement. NYSE Reporting of BancGroup Common Stock Issued in the Merger The shares of BancGroup common stock to be issued in the merger will be listed on the NYSE. Subsequent sales of BancGroup common stock issued in the merger will generally be reported on the NYSE. Management Following the Merger The management of BancGroup will not change in connection with the merger. 39 PROPOSAL 2: THE 280G PAYMENTS In addition to voting on the proposal to approve the merger agreement, Mercantile shareholders are being asked to consider and approve certain 280G payments to Roy J. Salley, the Chief Executive Officer of Mercantile and its subsidiary First Mercantile Bank. Mercantile, however, has agreed not to make any payments to any employee of Mercantile that would fail to be deductible for federal income tax purposes by virtue of Section 280G of the Internal Revenue Code. Section 280G provides that payments to officers, employees or shareholders of more than 1% of the outstanding shares of Mercantile common stock, which would otherwise be deductible expenses of an employer for federal income tax purposes, will not be deductible to the extent such payment may be characterized as a "parachute payment." Generally speaking, a "parachute payment" occurs when there is a change in control of an employer and, as a result, certain employees receive payments in the nature of compensation equal to or greater than three times their average annual compensation for the five years preceding the taxable year in which the change in control occurs. The amount of the payment that exceeds 299% of the employee's average annual compensation constitutes a "parachute payment," or a 280G payment. Any payment in violation of Section 280G will not be deductible by Mercantile and will be subject to a 20% excise tax payable by the recipient. In connection with the merger, it is possible that the following payments would constitute 280G payments: . the rights of the officers and directors to the automatic accelerated vesting of Mercantile options under the existing Mercantile option agreements, . the payments made to certain officers pursuant to the merger agreement, or . the potential payments under certain other agreements. The Internal Revenue Code contains an exemption for 280G payments by a corporation whose stock is not publicly traded on an established securities market if disinterested shareholders owning more than 75% of the voting power of such corporation's stock approve the payment. The shares of Mercantile common stock are not considered publicly traded on an established securities market for this purpose. Accordingly, to the extent the shareholder approval requirements of Section 280G are satisfied with respect to the payments to Mr. Sally, such payments will not be considered to be parachute payments and therefore would not give rise to an excess parachute payment subject to loss of deductibility and the 20% excise tax. Summary of Payments Mr. Salley is entitled to receive the following payments in connection with the consummation of the merger: . on December 31, 1997, Mr. Salley received a grant of options to purchase 40,000 shares of Mercantile common stock at an exercise price of $10.00 per share, of which 8,000 options remain unvested. Although the exact amount of the payment resulting from the acceleration of Mr. Salley's Mercantile options cannot be known until the Market Value of the BancGroup common stock is established, if the Market Value of the BancGroup common stock as of the Effective Date is $15.00 or higher per share, the amount of the payment resulting from the acceleration of Mr. Salley's vesting in the options, calculated in accordance with Section 280G, is estimated to be $41,933. . in the event Mr. Salley elects to participate in the cash free exchange of his Mercantile options and receive either cash or BancGroup common stock, he will be entitled to receive a cash bonus equal to 34% of the value of the cash or BancGroup common stock received. Although the exact amount of this cash bonus cannot be known until the Market Value of the BancGroup common stock is established, if the Market Value of BancGroup common stock as of the Effective Date is $15.00 or more per share, Mr. Salley would be entitled to a payment of $574,056 at closing. . the Mercantile Board of Directors agreed to pay Mr. Salley a cash bonus if certain conditions were satisfied. These conditions included the successful sale of Mercantile at a price greater than $40.00 per share. Pursuant to that agreement, Mr. Salley will receive at the closing of the merger a cash bonus of 40 0.75% of the merger consideration paid to Mercantile shareholders. Although the exact amount of this performance cash bonus cannot be known until the Market Value of BancGroup common stock is established, if the Market Value of the BancGroup common stock as of the Effective Date is $15.00 or greater per share, Mr. Salley will be entitled to receive a cash bonus of approximately $523,439. Pursuant to Section 280G of the Code, only that portion of the payments to Mr. Salley described above that exceeds $719,822 needs to be approved by the Mercantile shareholders. Approval of 280G Payments In order to avoid the loss of deductibility to Mercantile and the 20% excise tax to Mr. Salley and to ensure that Mercantile will not breach the merger agreement, Mercantile shareholders are being asked to approve the 280G payments to Mr. Salley. Mr. Salley has executed a waiver letter, pursuant to which he waives his right to that portion of any 280G payment that would cause the 280G payment to constitute a parachute payment under Section 280G of the Code in the event Mercantile fails to obtain the requisite shareholder approval. Even if the proposal to approve the 280G payments is not approved by the Mercantile shareholders, Mr. Salley will still receive $719,822 at the closing of the merger. This payment will consist of the acceleration of Mr. Salley's vesting in his options, the payment equal to 34% of the value of his Mercantile options exchanged for cash or BancGroup common stock, to the extent that he elects to do so, and to the extent those two payments do not exceed $719,822, that portion of the performance cash bonus that when added to the first two payments would equal $719,822. If Mercantile's shareholders approve proposal 2, Mr. Salley will receive the balance of the performance cash bonus at closing. As described above, Section 280G provides an exemption from the adverse federal income tax consequences if the disinterested shareholders holding more than 75% of the voting power of Mercantile common stock immediately preceding the effective time of the merger approve the 280G payments then the 280G payments will not be considered parachute payments and, therefore, will not cause a loss of deductability or a 20% excise tax. Mr. Salley and his spouse, parents, children and grandchildren are disqualified from voting on the proposal to approve the 280G payments, and shares of Mercantile common stock beneficially owned by such persons will not be treated as outstanding for purposes of computing the necessary vote to approve their payment. At the record date, Mr. Salley owned 100 shares of Mercantile common stock, representing less then 1% of the shares of Mercantile common stock entitled to vote at the special meeting. Accordingly, the approval of the 280G payments for Mr. Salley will require the affirmative vote of more than 75% of the remaining 1,336,652 shares, or at least 1,002,489 shares of Mercantile common stock. Finally, even without the shareholder vote referenced above, any portion of a 280G payment will be reduced to the extent, if any, that Mercantile demonstrates by clear and convincing evidence that some or all of such 280G payment is "reasonable compensation" for services to be rendered to BancGroup after the merger. Any portion of a 280G payment will be reduced to the extent, if any, that Mercantile demonstrates by clear and convincing evidence that some or all of such 280G payment is "reasonable compensation" for services rendered to Mercantile prior to the merger. The approval of the 280G payments is not a condition precedent to consummation of the merger. If the Mercantile shareholders do not approve any of the payments, Mr. Salley will not receive any payment that would violate Section 280G of the Code. Payment of the 280G payments will not affect the amount to be received by the Mercantile shareholders if the merger agreement is approved. THE BOARD OF DIRECTORS OF MERCANTILE BELIEVES THAT THE 280G PAYMENTS TO MR. SALLEY IS IN THE BEST INTEREST OF THE SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO APPROVE THE 280G PAYMENTS TO MR. SALLEY. 41 COMPARATIVE MARKET PRICES AND DIVIDENDS Mercantile. Presently, no active trading market exists for the Mercantile common stock and management of Mercantile does not anticipate that a market for Mercantile common stock will develop. No registered broker/dealer makes a market in Mercantile common stock, and Mercantile common stock is not listed or quoted on any stock exchange or automated quotation system. Mercantile acts as its own transfer agent and registrar. Occasionally, management of Mercantile becomes aware of trades of shares of its common stock and the prices at which these trades were executed. The following table sets forth the high and low sales price to the extent known to management of Mercantile for trades in its common stock for each quarter during 1999, 2000 and 2001: Number Number of Shares High Low of Trades Traded ------ ------ --------- --------- 1999 First Quarter. $ -- $ -- -- -- Second Quarter -- -- -- -- Third Quarter. -- -- -- -- Fourth Quarter -- -- -- -- 2000 First Quarter. $ -- $ -- -- -- Second Quarter 22.50 22.50 56 145,140(1) Third Quarter. 22.50 22.50 58 119,195(1) Fourth Quarter 68,350(1) 22.50 22.50 24 2001 First Quarter. $22.50 $22.50 49 131,400(1) Second Quarter 22.50 22.50 4 166,667(1) Third Quarter. 27.00 27.00 20 37,037(2) Fourth Quarter -- -- -- -- -------- (1) Represents the issuance of shares of Mercantile common stock for $22.50 per share, in cash, in an offering exempt from registration under the Securities Act.

The prices given above represent actual trades but may not include all trades that occurred during the reported period. The prices given are the result of limited trading and may not be representative of the actual fair market value of the Mercantile common stock. Mercantile is not obligated to register its common stock or, upon any registration, to create a market for its shares. Thus, a holder of Mercantile common stock may be unable to liquidate his or her investment and must be able to bear the economic risk of such investment indefinitely. 42 BancGroup. BancGroup common stock is listed for trading on the NYSE under the symbol "CNB." The following table indicates the high and low sales prices of the BancGroup common stock as reported on the NYSE since January 1, 1999.

(3) If the merger had closed on November 29, 2001, and assuming that the Market Value of BancGroup common stock had also been $14.00, 3.4808 shares of BancGroup common stock would have been exchanged for each share of Mercantile common stock. 43 BANCGROUP CAPITAL STOCK AND DEBENTURES BancGroup's authorized capital stock consists of 200,000,000 shares of BancGroup common stock, par value $2.50 per share and 1,000,000 shares of preference stock.

BancGroup Common Stock Dividends. Subject to the rights of holders of Preference Stock, if any, to receive certain dividends prior to the declaration of dividends on shares of BancGroup common stock, when and as dividends, payable in cash, stock or other property, are declared by the BancGroup board of directors, the holders of BancGroup common stock are entitled to share ratably in such dividends. Voting Rights. Each holder of BancGroup common stock has one vote for each share held on matters presented for consideration by the stockholders. Preemptive Rights. The holders of BancGroup common stock have no preemptive rights to acquire any additional shares of BancGroup. Issuance of Stock. The BancGroup Certificate authorizes the board of directors of BancGroup to issue authorized shares of BancGroup common stock without stockholder approval. However, BancGroup's common stock is listed on the NYSE, which requires stockholder approval of the issuance of additional shares of BancGroup common stock under certain circumstances. Liquidation Rights. In the event of liquidation, dissolution or winding-up of BancGroup, whether voluntary or involuntary, the holders of BancGroup common stock will be entitled to share ratably in any of its assets or funds that are available for distribution to its stockholders after the satisfaction of its liabilities (or after adequate provision is made therefor) and after preferences of any outstanding Preference Stock. BancGroup Preference Stock The BancGroup preference stock may be issued from time to time as a class without series, or if so determined by the board of directors of BancGroup, either in whole or in part in one or more series. The voting 44 rights, and such designations, preferences and relative, participating, optional or other special rights, if any, and the qualifications, limitations or restrictions thereof, if any, including, but not limited to, the dividend rights, conversion rights, redemption rights and liquidation preferences, if any, of any wholly unissued series of preference stock, or of the entire class of preference stock if none of such shares has been issued, the number of shares constituting any such series and the terms and conditions of the issue thereof may be fixed by resolution of the board of directors of BancGroup. Preference stock may have a preference over the BancGroup common stock with respect to the payment of dividends and the distribution of assets in the event of the liquidation or winding-up of BancGroup and such other preferences as may be fixed by the board of directors of BancGroup. BancGroup Debt BancGroup has 7.50% Convertible Subordinated Debentures due March 31, 2011 ("1986 Debentures") issued in 1986 that are convertible at any time into shares of BancGroup common stock, at the conversion price of $7.00 principal amount of 1986 Debentures, subject to adjustment upon the occurrence of certain events, for each share of stock received. The 1986 Debentures are redeemable at the option of BancGroup at the face amount plus accrued interest. In the event all of the remaining 1986 Debentures are converted into shares of BancGroup common stock in accordance with the 1986 Indenture, approximately 399,000 shares of such common stock would be issued. BancGroup also has 7.00% Convertible Subordinated Debentures due December 31, 2004 ("1994 Debentures"), that were issued by D/W Bankshares prior to being merged into BancGroup. The 1994 Debentures are convertible into BancGroup common stock, at the conversion price of $7.58 principal amount of the 1994 Debentures, subject to adjustment upon occurrence of certain events, for each share of stock received. In the event all of the remaining 1994 Debentures are converted into shares of BancGroup common stock in accordance with the 1994 Indenture, approximately 96,000 shares of such common stock would be issued. In connection with the ASB Bancshares, Inc. acquisition, on February 5, 1998, BancGroup issued $7,725,000 of variable rate subordinated debentures due February 5, 2008 ("1998 Debentures"). These variable rate subordinated debentures bear interest equal to the New York Prime Rate minus 1% (but in no event less than 7% per annum). On March 15, 1999, BancGroup issued $100 million of subordinated notes, due March 15, 2009. The notes bears interest at 8.00% per annum and are not subject to redemption prior to maturity. On January 29, 1997, BancGroup issued, through a special purpose trust, $70 million of Trust Preferred Securities. The securities bear interest at 8.92% per annum and are subject to redemption by BancGroup, in whole or in part at any time after January 29, 2007 until maturity in January 2027. Circumstances are remote that redemption will occur prior to maturity. On May 23, 2001, Colonial Bank issued $150 million in subordinated notes at 9.375% per annum due June 1, 2011 for general corporate and banking purposes in the ordinary course of business. This debt qualifies as Tier 2 capital. In connection with this issuance, BancGroup executed an interest rate swap whereby BancGroup will receive a fixed rate and pay a floating rate, effectively converting the fixed rate notes to floating. The result of this interest rate swap created a current effective rate on the notes for the fourth quarter ending December 31, 2001 of 6.32% per annum. The subordinated debentures, notes and Trust Preferred Securities described above are subordinate to substantially all remaining liabilities of BancGroup. BancGroup had long-term FHLB Advances outstanding of $1,361,938,000 at December 31, 2001. These advances bear interest rates of 3.635% to 6.58% per annum and mature from . 45 BancGroup has received funds under reverse repurchase agreements with Keefe, Bruyette & Woods. At December 31, 2001, BancGroup had long-term reverse repurchase agreements outstanding of $88 million. These agreements, which are collateralized by mortgage-backed securities, bear interest rates of 5.84% to 6.03% per annum and mature in 2003. Changes in Control Certain provisions of the BancGroup Certificate and the BancGroup Bylaws may have the effect of preventing, discouraging or delaying any change in control of BancGroup. The authority of the BancGroup board of directors to issue BancGroup Preferred Stock with such rights and privileges, including voting rights, as it may deem appropriate may enable BancGroup's board of directors to prevent a change in control despite a shift in ownership of the BancGroup common stock. See "General" and "Preferred Stock." In addition, the power of BancGroup's board of directors to issue additional shares of BancGroup common stock may help delay or deter a change in control by increasing the number of shares needed to gain control. See "BancGroup common stock." The following provisions also may deter any change in control of BancGroup. Classified Board. BancGroup's board of directors is classified into three classes, as nearly equal in number as possible, with the members of each class elected to three-year terms. Thus, one-third of BancGroup's board of directors is elected by stockholders each year. With this provision, two annual elections are required in order to change a majority of the board of directors. There are currently 18 directors of BancGroup. This provision of the BancGroup Certificate also stipulates that (i) directors can be removed only for cause upon a vote of 80% of the voting power of the outstanding shares entitled to vote in the election of directors, voting as a class, (ii) vacancies in the board of directors may only be filled by a majority vote of the directors remaining in office, (iii) the maximum number of directors shall be fixed by resolution of the board of directors, and (iv) the provisions relating to the classified board of directors can only be amended by the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares entitled to vote in the election of directors, voting as a class. Business Combinations. Certain "Business Combinations" of BancGroup with a "Related Person" may only be undertaken with the affirmative vote of at least 75% of the outstanding shares of "Voting Stock," plus the affirmative vote of at least 67% of the outstanding shares of Voting Stock, not counting shares owned by the Related Person, unless the Continuing Directors of BancGroup approve such Business Combination. A "Related Person" is a person, or group, who owns or acquires 10% or more of the outstanding shares of BancGroup common stock, provided that no person shall be a Related Person if such person would have been a Related Person on April 20, 1994. An effect of this provision may be to exclude Robert E. Lowder, the current Chairman and Chief Executive Officer of BancGroup, and certain members of his family from the definition of Related Person. A "Continuing Director" is a director who was a member of the board of directors immediately prior to the time a person became a Related Person. This provision may not be amended without the affirmative vote of the holders of at least 75% of the outstanding shares of Voting Stock, plus the affirmative vote of the outstanding shares of at least 67% of the outstanding Voting Stock, excluding shares held by a Related Person. This provision may have the effect of giving the incumbent board of directors a veto over a merger or other Business Combination that could be desired by a majority of BancGroup's stockholders. As of February 20, 2001, the board of directors of BancGroup owned approximately 7.9% of the outstanding shares of BancGroup common stock. Board Evaluation of Mergers. The BancGroup Certificate permits the board of directors to consider certain factors such as the character and financial stability of the other party, the projected social, legal, and economic effects of a proposed transaction upon the employees, suppliers, regulatory agencies and customers and communities of BancGroup, and other factors when considering whether BancGroup should undertake a merger, sale of assets, or other similar transaction with another party. This provision may not be amended except by the affirmative vote of at least 80% of the outstanding shares of BancGroup common stock. This provision may give greater latitude to the board of directors in terms of the factors which the board may consider in recommending or rejecting a merger or other Business Combination of BancGroup. 46 Director Authority. The BancGroup Certificate prohibits stockholders from calling special stockholders' meetings and acting by written consent. It also provides that only BancGroup's board of directors has the authority to undertake certain actions with respect to governing BancGroup such as appointing committees, electing officers, and establishing compensation of officers, and it allows the board of directors to act by majority vote. Bylaw Provisions. The BancGroup Bylaws provide that stockholders wishing to propose nominees for the board of directors or other business to be taken up at an annual meeting of BancGroup shareholders must comply with certain advance written notice provisions. These bylaw provisions are intended to provide for the more orderly conduct of stockholders' meetings but could make it more difficult for shareholders to nominate directors or introduce business at shareholders' meetings. Delaware Business Combination Statute. Subject to some exceptions, Delaware law prohibits BancGroup from entering into certain "business combinations" involving persons beneficially owning 15% or more of the outstanding BancGroup common stock (or one who is an affiliate of BancGroup and has over the past three years beneficially owned 15% or more of such stock) (either, for the purpose of this paragraph, an "Interested Stockholder"), unless the board of directors has approved either . the business combination, or . prior to the stock acquisition by which such person's beneficial ownership interest reached 15% (a "Stock Acquisition"), the Stock Acquisition. The prohibition lasts for three years from the date of the Stock Acquisition. Notwithstanding the preceding, Delaware law allows BancGroup to enter into a business combination with an Interested Stockholder if . the business combination is approved by BancGroup's board of directors and authorized by an affirmative vote of at least 66 2/3% of the outstanding voting stock of BancGroup which is not owned by the Interested Stockholder, or . upon consummation of the transaction which resulted in the shareholder becoming an Interested Stockholder, such shareholder owned at least 85% of the outstanding BancGroup common stock (excluding BancGroup common stock held by officers and directors of BancGroup or by certain BancGroup stock plans). These provisions of Delaware law apply simultaneously with the provisions of the BancGroup Certificate relating to business combinations with a related person, described above at "Business Combinations," but they are generally less restrictive than the BancGroup Certificate. Control Acquisitions. As it relates to BancGroup, the Change in Bank Control Act of 1978 prohibits a person or group of persons from acquiring "control" of a bank holding company unless the Federal Reserve has been given 60 days' prior written notice of such proposed acquisition and within that time period the Federal Reserve has not issued a notice disapproving the proposed acquisition or extending for up to another 30 days the period during which such a disapproval may be issued. An acquisition may be made prior to the expiration of the disapproval period if the Federal Reserve issues written notice of its intent not to disapprove the transaction. Under a rebuttable presumption established by the Federal Reserve, the acquisition of more than 10% of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as BancGroup, would, under the circumstances set forth in the presumption, constitute the acquisition of control. The receipt of revocable proxies, provided the proxies terminate within a reasonable time after the meeting to which they relate, is not included in determining percentages for change in control purposes. 47 COMPARATIVE RIGHTS OF SHAREHOLDERS If the merger is consummated, shareholders of Mercantile, except those perfecting dissenters' rights, will become holders of BancGroup common stock. The rights of the holders of the Mercantile common stock who become holders of BancGroup common stock following the merger will be governed by the BancGroup Certificate and the BancGroup Bylaws, as well as the laws of Delaware, the state in which BancGroup is incorporated. The following summary compares the rights of the holders of Mercantile common stock with the rights of the holders of the BancGroup common stock. For a more detailed description of the rights of the holders of BancGroup common stock, including certain features of the BancGroup Certificate of Incorporation and the DGCL that might limit the circumstances under which a change in control of BancGroup could occur, see "BancGroup Capital Stock and Debentures." The following information is qualified in its entirety by the BancGroup Certificate and the BancGroup Bylaws, and Mercantile's Articles of Incorporation and Bylaws, the DGCL and the TBCA. Director Elections Mercantile. Mercantile's Bylaws provide for a board of directors consisting of not less than one nor more than 15 directors. Currently, the number of directors is fixed at 13. Directors are elected at the annual meeting of shareholders and hold office until the next annual meeting of shareholders. The Articles of Mercantile deny shareholders the right to cumulate votes in the election of directors. BancGroup. BancGroup's directors are elected to terms of three years with approximately one-third of the Board to be elected annually. There is no cumulative voting in the election of directors. See "BancGroup Capital Stock and Debentures--Changes in Control--Classified Board." Removal of Directors Mercantile. A director may be removed at any time, with or without cause, at any duly called special or annual meeting of the shareholders of Mercantile, by the affirmative vote of a majority in number of shares present at such meeting and entitled to vote for the election of such director. BancGroup. The BancGroup Certificate provides that a director may be removed from office, but only for cause and by the affirmative vote of the holders of at least 80% of the voting shares then entitled to vote at an election of directors. Voting Mercantile. Shareholders of Mercantile are entitled to one vote for each share of Mercantile common stock held. The Articles of Mercantile deny stockholders the right to cumulate votes in the election of directors. BancGroup. Each stockholder of BancGroup is entitled to one vote for each share of BancGroup common stock held, and such holders are not entitled to cumulative voting rights in the election of directors. Preemptive Rights Mercantile. Mercantile's Articles deny holders of Mercantile common stock any preemptive rights to subscribe for or acquire additional shares of common stock that may be issued by Mercantile. BancGroup. The holders of BancGroup common stock have no preemptive rights to acquire any additional shares of BancGroup common stock or any other shares of BancGroup capital stock. 48 Directors' Liability Mercantile. The Articles of Mercantile provide that a director will not incur liability to Mercantile and its stockholders for monetary damages for an act or omission that occurs in the director's capacity as a director, unless that director . commits a breach of his or her duty of loyalty to Mercantile and its stockholders; . commits an act or omission not in good faith that constitutes a breach of the duty of the director to Mercantile or an act or omission that involves intentional misconduct or a knowing violation of the law; . engages in a transaction from which the director receives an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office; or . engages in an act or omission for which the liability of a director is expressly provided for by statute. This provision protects Mercantile's directors against personal liability for monetary damages from breaches of their duty of care. It does not eliminate the director's duty of care and has no effect on the availability of equitable remedies such as injunction or rescission, based upon a director's breach of a director's duty of care. BancGroup. The BancGroup Certificate provides that a director of BancGroup will have no personal liability to BancGroup or its stockholders for monetary damages for breach of fiduciary duty as a director except . for any breach of the director's duty of loyalty to the corporation or its stockholders; . for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; . for the payment of certain unlawful dividends and the making of certain stock purchases or redemptions; or . for any transaction from which the director derived an improper personal benefit. This provision would absolve directors of personal liability for negligence in the performance of duties, including gross negligence. It would not permit a director to be exculpated, however, for liability for actions involving conflicts of interest or breaches of the traditional "duty of loyalty" to BancGroup and its stockholders, and it would not affect the availability of injunctive or other equitable relief as a remedy. Indemnification Mercantile will only indemnify a person that: . acted in good faith, . reasonably believed that any actions taken in an official capacity were in Mercantile's best interests and that any actions taken outside an official capacity were not opposed to Mercantile's best interests, and . in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. A person found liable to Mercantile or found liable on the basis that the person improperly received a personal benefit may only be indemnified for reasonable expenses actually incurred by the person in connection with the proceeding; however, if the person is found liable for willful or intentional misconduct in the performance of his duty to Mercantile, Mercantile shall not indemnify him in any respect. Mercantile is required to indemnify an officer, director or past director against reasonable expenses he or she incurs in connection with a proceeding in which he or she is a party because he or she is a director or officer of Mercantile, or, while a director, has served as a director, officer or other functionary of another entity, if he or she has been wholly successful in the defense of the proceeding. Mercantile may purchase and maintain insurance on behalf of any person who is or was a director or officer of Mercantile against any liability asserted against that person and incurred by that person in such a capacity, whether or not Mercantile would have the power to indemnify that person against that liability under the TBCA. 49 Mercantile maintains an officers' and directors' insurance policy pursuant to which officers and directors of Mercantile would be entitled to indemnification beyond that permitted by the Articles. BancGroup. The BancGroup Certificate provides that directors, officers, employees and agents of BancGroup shall be indemnified to the full extent permitted under the DGCL. Section 145 of the DGCL contains detailed and comprehensive provisions providing for indemnification of directors and officers of Delaware corporations against expenses, judgments, fines and settlements in connection with litigation. Under the DGCL, other than an action brought by or in the right of BancGroup, such indemnification is available if it is determined that the proposed indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of BancGroup and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In actions brought by or in the right of BancGroup, such indemnification is limited to expenses (including attorneys' fees) actually and reasonably incurred in the defense or settlement of such action if the indemnity acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of BancGroup and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person has been adjudged to be liable to BancGroup unless and only to the extent that the Delaware Court of Chancery or the court in which the action was brought determines upon application that in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. To the extent that the proposed indemnity has been successful on the merits or otherwise in defense of any action, suit or proceeding (or any claim, issue or matter therein), he or she must be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. BancGroup maintains an officers' and directors' insurance policy and a separate indemnification agreement pursuant to which officers and directors of BancGroup would be entitled to indemnification against certain liabilities, including reimbursement of certain expenses that extends beyond the minimum indemnification provided by Section 145 of the DGCL. Special Meetings of Shareholders; Action Without a Meeting Mercantile. Pursuant to the Mercantile's Bylaws and the TBCA, the president, the board of directors, or the holders of not less than 10 percent of the shares of Mercantile common stock entitled to vote at a meeting may call a special meeting of the shareholders of Mercantile. Any action required to be taken at a meeting pursuant to the TBCA may be taken without a meeting if a consent in writing setting forth the action taken is signed by the holders of not less than the minimum number of votes that would have been necessary to take such action at a meeting at which the holders of all of the shares entitled to vote on the action were present and voted. BancGroup. Under the BancGroup Certificate, a special meeting of BancGroup's stockholders may only be called by a majority of the BancGroup board of directors or by the chairman of the board of directors of BancGroup. Holders of BancGroup common stock may not call special meetings or act by written consent. Mergers, Share Exchanges and Sales of Assets Mercantile. Under the TBCA, the holders of at least two-thirds of the outstanding shares entitled to vote thereon as a class must approve an agreement for the merger, consolidation, sale of substantially all of the assets, or dissolution, of a Texas corporation. The TBCA also provides, however, that the stockholders of a Texas corporation need not vote on the transaction if: . the corporation is the sole surviving corporation in the merger; . the articles of incorporation of the corporation will not differ from its articles before the merger; . each shareholder before the merger will own the same number of shares, with identical preferences and designations, immediately after the effective date of the merger; 50 . the number of shares issued in connection with the merger does not exceed 20% of the voting power immediately before the merger; . the number of shares issued in the merger does not exceed 20% of the number of shares outstanding immediately before the merger; and . the board of directors of the corporation adopts a resolution approving the plan of merger. BancGroup. The DGCL provides the mergers and sales of substantially all of the assets of Delaware corporations must be approved by a majority of the outstanding stock of the corporation entitled to vote thereon. The DGCL also provides, however, that the stockholders of the corporation surviving a merger need not approve the transaction if: . the agreement of merger does not amend in any respect the certificate of incorporation of such corporation; . each share of stock of such corporation outstanding immediately prior to the effective date of the merger is to be an identical outstanding or treasury share of the surviving corporation after the effective date of the merger; and . either no shares of common stock of the surviving corporation and no shares, securities or obligations convertible into such stock are to be issued or delivered under the plan of merger, or the authorized unissued shares or the treasury shares of common stock of the surviving corporation to be issued or delivered under the plan of merger plus those initially issuable upon conversion of any other shares, securities or obligations to be issued or delivered under such plan do not exceed 20% of the shares of common stock of such corporation outstanding immediately prior to the effective date of the merger. See also "BancGroup Capital Stock and Debentures--Changes in Control" for a description of the statutory provisions and the provisions of the BancGroup Certificate relating to changes of control of BancGroup. See "Anti-takeover Statutes" for a description of additional restrictions on business combination transactions. Amendment of Articles or Certificate of Incorporation and Bylaws Mercantile. The TBCA provides that pursuant to a resolution adopted by the board of directors of a Texas corporation and written notice of a special or annual meeting to each shareholder of record, a proposed amendment to the corporation's articles of incorporation is adopted upon the receipt of the affirmative vote of the holders of two-thirds of the shares entitled to vote, unless any class of shares is entitled to vote as a class, in which event the proposed amendment is adopted upon receiving the affirmative vote of the holders of at least two-thirds of the shares within each class entitled to vote thereon as a class and two-thirds of the total outstanding shares entitled to vote thereon. The Articles of Mercantile do not contain any provision altering the statutory provisions governing amendment of the articles of incorporation. The board of directors of Mercantile may amend the Bylaws at any meeting of the directors at which a quorum is present, provided notice of the proposed amendment was given, upon the affirmative vote of a majority of directors present. At a duly called meeting of the shareholders of Mercantile, a majority of the shareholders present may amend or repeal such amendment to the Bylaws. BancGroup. Under the DGCL, a Delaware corporation's certificate of incorporation may be amended by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote thereon, and a majority of the outstanding stock of each class entitled to vote as a class, unless the certificate requires the vote of a larger portion of the stock. The BancGroup Certificate requires "super-majority" stockholder approval to amend or repeal any provision of, or adopt any provision inconsistent with, certain provisions in the BancGroup Certificate governing: . the election or removal of directors; 51 . business combinations between BancGroup and a Related Person; and . board of directors evaluation of business combination procedures. See "BancGroup Capital Stock and Debentures--Changes in Control." As is permitted by the DGCL, the Certificate gives the Board of Directors the power to adopt, amend or repeal the BancGroup Bylaws. The stockholders entitled to vote have concurrent power to adopt, amend or repeal the BancGroup Bylaws. Rights of Dissenting Stockholders Mercantile. Holders of Mercantile common stock have dissenter's and appraisal rights under Articles 5.11, 5.12 and 5.13 of the TBCA. Under these provisions, Mercantile shareholders may dissent from certain corporate actions proposed by Mercantile's management and receive the fair value of their shares of Mercantile common stock as of or immediately prior to the effective time of the proposed corporate action. A summary of Articles 5.11, 5.12 and 5.13 is set forth under the caption "The Merger--Rights of Dissenting Shareholders," and such provisions are included as Appendix B. BancGroup. Under the DGCL, a stockholder has the right, in certain circumstances, to dissent from certain corporate transactions and receive the fair value of his or her shares in cash in lieu of the consideration he or she otherwise would have received in the transaction. For this purpose, "fair value" may be determined by all generally accepted techniques of valuation used in the financial community, excluding any element of value arising from the accomplishment or expectation of the transaction, but including elements of future value that are known or susceptible of proof. Such fair value is determined by the Delaware Court of Chancery, if a petition for appraisal is timely filed. Appraisal rights are not available, however, to stockholders of a corporation: . if the shares are listed on a national securities exchange (as is BancGroup common stock) or quoted on the Nasdaq NMS, or held of record by more than 2,000 stockholders (as is BancGroup common stock); and . stockholders are permitted by the terms of the merger or consolidation to accept in exchange for their shares: . shares of stock of the surviving or resulting corporation; . shares of stock of another corporation listed on a national securities exchange or held of record by more than 2,000 stockholders; . cash in lieu of fractional shares of such stock; or . any combination thereof. Stockholders are not permitted appraisal rights in a merger if such corporation is the surviving corporation and no vote of its stockholders is required. Preferred Stock Mercantile. Mercantile's Articles do not authorize the issuance of preferred stock. BancGroup. The BancGroup Certificate authorizes the issuance of 1,000,000 shares of preferred stock from time to time by resolution of the board of directors of BancGroup. Such preferred stock is denominated as "preference stock" in the BancGroup Certificate. Currently, no shares of preference stock are issued and outstanding. See "BancGroup Capital Stock and Debentures--Preference Stock." Effect of the Merger on Mercantile Shareholders As of , 2002, Mercantile had 266 shareholders of record and 1,336,752 outstanding shares of common stock. As of December 31, 2001, there were 115,244,185 shares of BancGroup common stock outstanding held by 9,179 stockholders of record. 52 Assuming that no dissenters' rights of appraisal are exercised in the merger, that the Mercantile options are exercised prior to the Effective Date, and the Market Value of BancGroup common stock is $14.57 (the closing price of BancGroup common stock as of January 23, 2002) on the Effective Date, an aggregate number of 5,460,511 shares of BancGroup common stock will be issued to the shareholders of Mercantile pursuant to the merger. These shares would represent approximately 4.5% of the total shares of BancGroup common stock outstanding after the merger, not counting any shares of BancGroup common stock that may be issued for reasons unconnected to the merger. Depending on actual events, the foregoing figures may be substantially different as of the Effective Date. The issuance of the BancGroup common stock pursuant to the merger will reduce the percentage interest of the BancGroup common stock currently held by each principal stockholder and each director and officer of BancGroup. Based upon the foregoing assumptions, as a group, the directors and officers of BancGroup who own approximately 8.1% of BancGroup's outstanding shares would own approximately 7.4% after the merger. See "Business of BancGroup--Voting Securities and Principal Stockholders." [INTENTIONALLY LEFT BLANK] 53 BUSINESS OF BANCGROUP General BancGroup is a Delaware corporation organized in 1974 as a bank holding company under the Bank Holding Act of 1956, as amended. Through its wholly-owned subsidiary, Colonial Bank, BancGroup conducts a general commercial banking business in the states of Alabama, Florida, Georgia, Nevada, Tennessee and Texas. At December 31, 2001, BancGroup had assets of $13.2 billion. As of December 31, 2001 Colonial Bank has a total of 261 branches, with 123 branches in Alabama, 98 branches in Florida, 23 branches in Georgia, 3 branches in Tennessee, 3 branches in Texas and 11 branches in Nevada. Colonial Bank conducts a general commercial banking business in its respective service areas. Colonial Bank offers a variety of demand, savings and time deposit products as well as extensions of credit through personal, commercial and mortgage loans within each of its market areas. Colonial Bank also provides additional services to its markets through cash management services, electronic banking services, credit card and merchant services and wealth management services. Wealth management services include trust services and the sales of various types of investment products such as mutual funds, annuities, stocks, municipal bonds and U.S. government securities. Voting Securities and Principal Stockholders As of December 31, 2001, BancGroup had issued and outstanding 115,244,185 shares of BancGroup common stock with approximately 9,179 stockholders of record. Each such share is entitled to one vote. In addition, as of that date, 3,577,421 shares of BancGroup common stock were subject to issuance upon exercise of options pursuant to BancGroup's stock option plans and up to 495,000 shares of BancGroup common stock were issuable upon conversion of BancGroup's 1986 Debentures and 1994 Debentures. There are currently 200,000,000 shares of BancGroup common stock authorized. The following table shows those persons who are known to BancGroup to be beneficial owners as of February 20, 2001 of more than five percent of outstanding BancGroup common stock.

BancGroup hereby incorporates such information by reference. BUSINESS OF MERCANTILE General Mercantile was organized under the laws of the State of Texas on November 18, 1998, for the purpose of indirectly acquiring all of the outstanding capital stock of First Mercantile Bank and becoming a bank holding company under the Bank Holding Company Act of 1956, as amended. Mercantile indirectly acquired all of the issued and outstanding stock of First Mercantile Bank in May 1999. Mercantile indirectly owns 100% of First Mercantile Bank through its direct ownership of 100% of the capital stock of Mercantile Delaware Bancorp, Inc., a Delaware corporation and intermediate bank holding company. In addition, Mercantile formed MBI Capital Trust I, a special purpose finance subsidiary, in August 2001 of which Mercantile owns all of the common securities. As of September 30, 2001, Mercantile had, on a consolidated basis, total assets of approximately $346.3 million, total loans (net of unearned discount and allowance for loan losses) of approximately $237.2 million, total deposits of approximately $297.9 million and approximately $24.6 million of stockholders' equity. Since becoming a bank holding company, Mercantile has sought to capitalize on the opportunities presented by the continued consolidation in the banking industry. Since opening in January 1998, Mercantile has grown steadily to a financial institution with over $300 million in assets as of September 30, 2001. A significant portion of that growth occurred in September 2001 when Mercantile acquired TownBank, a National Association, located in Mesquite, Texas (approximately 14 miles east of Dallas, Texas), which had immediately prior to Mercantile's acquisition, total assets of approximately $85.0 million, total loans (net of unearned discount and allowance for loan losses) of approximately $48.2 million, and total deposits of approximately $75.1 million. Mercantile conducts its community banking business through five banking offices: four in the greater Dallas metropolitan area and one in Austin, Texas. Through its banking offices, Mercantile offers a variety of traditional loan and deposit products to its customers, primarily small to medium-sized businesses and individual consumers. For businesses, Mercantile provides term loans, lines of credit and loans for working capital, business expansion and the purchase of equipment and machinery, interim construction loans for builders and owner occupied commercial real estate loans. Mercantile offers consumers automobile loans, home mortgage loans, debit cards, cash management services and Internet banking. Customers of Mercantile are provided with a full complement of traditional deposit products. Along with steady asset growth, Mercantile's financial performance has historically been characterized by consistent core earnings and low net charge-offs. The diverse economic nature of the local markets that it serves provide Mercantile with a varied customer base and allows it to spread its lending risks among different industries. Mercantile's market area consists of a dynamic metropolitan area with a correspondingly broad array of economic activities including public, financial and medical services, real estate development and technology. Mercantile derives its revenues primarily from the operations of its subsidiary bank in the form of dividends. First Mercantile Bank Activities First Mercantile Bank is a national banking association that was organized in January 1998 and is regulated by the Office of the Comptroller of the Currency and the FDIC. First Mercantile Bank considers its primary market areas to be in the cities of Dallas and Austin, Texas and surrounding areas. First Mercantile Bank serves 56 this market through its main office and two branches in Dallas, Texas, one branch in Mesquite, Texas and a branch located in Austin, Texas. First Mercantile Bank also has a mobile branch to service the needs of its customers. First Mercantile Bank is engaged in substantially all of the business operations customarily conducted by independent financial institutions in Texas, including the acceptance of checking, savings and certificates of deposit and the making of commercial and consumer loans, real estate loans, and other installment and term loans. First Mercantile Bank does not offer trust services. First Mercantile Bank does a substantial amount of business with individuals, as well as with customers in small to medium-sized commercial, industrial and professional businesses. For the convenience of its customers, First Mercantile Bank offers drive-through banking facilities, automated teller machines, night depositories, personalized checks, charge cards through correspondent banks and safe deposit boxes. First Mercantile Bank's services include cashier's checks, travelers' checks, domestic and foreign wire transfers, account research, stop payments, telephone transfers between accounts and photocopies. Competition Mercantile experiences competition in both lending and attracting funds from other commercial banks, savings banks, savings and loan associations, credit unions, finance companies, pension trusts, mutual funds, insurance companies, mortgage bankers and brokers, brokerage and investment banking firms, asset-based non-bank lenders, government agencies and certain other non-financial institutions, including retail stores, which may offer more favorable financing alternatives than Mercantile. Mercantile also competes with companies located outside of the Dallas and Austin markets that provide financial services to persons within these markets. Some of Mercantile's current and potential competitors have larger customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than First Mercantile Bank, and some of them are not subject to the same degree of regulation as Mercantile. Lending Activities Mercantile offers a range of lending services, including real estate, consumer and commercial and industrial loans. Mercantile provides general commercial lending services for corporate and other business clients as a part of its efforts to serve the local communities in which it operates. In addition, Mercantile provides loans for 1-4 family residences and, to a lesser extent, for consumer purposes. Mercantile had consolidated net loans of $237.2 million at September 30, 2001, representing 68.5% of Mercantile's consolidated assets. Mercantile's commercial and industrial loans include operating lines of credit and term loans made to small businesses primarily based on their ability to repay the loan from the business's cash flow. Business assets such as equipment, accounts receivable and inventory typically secure these loans. These loans typically involve larger loan balances than consumer or residential loans and are generally dependent on the business's cash flow and, thus, may be subject to adverse conditions in the general economy or in a specific industry. Management of Mercantile reviews the borrower's cash flows when deciding whether to grant the credit to evaluate whether estimated future cash flows will be adequate to service the principal and interest of the loan. Commercial real estate loans are primarily secured by borrower-occupied business real estate and rely on the ability of the related business to generate adequate cash flow to service the debt. Mercantile generally originates commercial real estate loans with a loan-to-value ratio of 80% or less. Management performs an analysis that is similar to the analysis used for commercial loans when deciding whether to grant a commercial real estate loan. 57 Mercantile provides construction loans secured by residential and business real estate. Management of Mercantile believes that it established its construction lending program in a manner to minimize the risks inherent in this type of lending by limiting the size of its loans on speculative projects. Mercantile does not generally make the permanent loan at the end of the construction phase. Construction loans also are generally made in amounts of 80% or less of the value of collateral. Residential real estate loans consist mainly of first and second mortgages on single family homes, with some multifamily loans. Loan-to-value ratios for these instruments are generally limited to 80%. The repayment of residential real estate loans is dependent primarily on the income and cash flows of the borrowers, with the real estate serving as a secondary or liquidation source of repayment. Mercantile periodically sells longer-term, lower-yielding mortgages on 1-4 family residences to the Federal National Mortgage Association, or FNMA, and other money center banks The rationale for these sales is to mitigate interest rate risk associated with holding long-term residential mortgages in the loan portfolio, to generate fee revenue from servicing, and still maintain the primary customer relationship. Although not a significant portion of Mercantile's loan portfolio, on occasion, Mercantile originates short-term residential real estate loans and home equity lines of credit that are secured by the borrower's residence. Such loans are made based on the borrower's ability to make repayment from employment and other income. Management of Mercantile assesses the borrower's ability to repay the debt through review of credit history and ratings, verification of employment and other income, review of debt-to-income ratios and other measures of repayment ability. Mercantile generally makes these loans in amounts of 80% or less of the value of collateral. Consumer installment loans to individuals include loans secured by automobiles and other consumer assets. Consumer loans for purchase of new automobiles do not exceed 100% of the retail price of the automobile. Loans for used cars generally do not exceed average loan value as stipulated in a recent auto industry used car price guide. Overdraft protection loans are unsecured personal lines of credit to individuals of demonstrated good credit character with reasonably assured sources of income and satisfactory credit histories. Consumer loans generally involve more risk than residential mortgage loans because of the type and nature of collateral and, in certain types of consumer loans, the absence of collateral. Because borrowers generally repay these loans from ordinary income, repayment may be adversely affected by job loss, divorce, illness or by general decline in economic conditions. Mercantile assesses the borrower's ability to make repayment through a review of credit history, credit ratings, debt-to-income ratios and other measures of repayment ability. Mercantile may renew loans at maturity when requested by a customer whose financial strength appears to support such renewal or when such renewal appears to be in the best interests of Mercantile. Mercantile requires payment of accrued interest in such instances and may adjust the rate of interest, require a principal reduction or modify other terms of the loan at the time of renewal. Deposit Activities Deposits represent the major source of Mercantile's funds for lending and other investment activities. Mercantile attracts deposits principally from within its primary market areas through the offering of a broad selection of deposit instruments, including checking accounts, money market accounts, regular savings accounts, term certificate accounts and individual retirement accounts. Although Mercantile will occasionally utilize Federal Home Loan Bank borrowings to provide a hedge on certain mortgages, it does not extensively engage in such activities. Interest rates paid, maturity terms, service fees and withdrawal penalties for the various types of accounts are established periodically by management based on Mercantile's liquidity requirements, growth goals and interest rates paid by competitors. Mercantile does not use brokers to attract deposits. At September 30, 2001, Mercantile had, on a consolidated basis, total deposits of approximately $297.9 million. Approximately 27% of Mercantile's consolidated deposits at September 30, 2001 were certificates of deposit. Generally, Mercantile attempts to maintain the rates paid on its deposits at a competitive level. Time 58 deposits of $100,000 and over made up approximately 20% of Mercantile's consolidated total deposits at September 30, 2001. Investments Mercantile invests a portion of its assets in obligations of the U.S. Treasury and other government agencies, obligations of state and municipal subdivisions, corporate obligations, collateralized mortgage obligations and pass-through certificates guaranteed by FNMA, Federal Home Loan Mortgage Corporation and Government National Mortgage Association. Mercantile classifies these securities as either held to maturity or available for sale according to management's intent. Mercantile manages its investments in relation to loan demand and deposit growth, and generally invests its excess funds at minimal risks while providing liquidity to fund increases in loan demand or to offset fluctuations in deposits. Federal funds sold represent the excess cash Mercantile has available over and above its daily cash needs. Mercantile invests this money on an overnight basis with approved correspondent banks. At September 30, 2001, Mercantile held, on a consolidated basis, approximately $44.0 million in various securities, which represented 13% of total consolidated assets. Employees As of September 30, 2001, Mercantile had 105 full-time and equivalent employees. Mercantile believes that it has a good relationship with its employees. Properties .

The place and date to which the special meeting would be adjourned would be announced at the special meeting. Proxies voted against the merger agreement and abstentions will not be voted to adjourn the special meeting. Abstentions and broker non-votes will not be voted on this matter but will not count as ''no'' votes. However, an abstention or a broker non-vote has the same effect as a ''no'' vote. If it is necessary to adjourn the special meeting and the adjournment is for a period of not more than 30 days from the original date of the special meeting, no notice of the time and place of the adjourned meeting need be given the Mercantile shareholders, other than an announcement made at the special meeting. The effect of any such adjournment would be to permit Mercantile to solicit additional proxies for approval of the merger agreement and the 280G payments. Such an adjournment would not invalidate any proxies previously filed as long as the record date for the adjourned meeting remained the same, including proxies filed by shareholders voting against the merger agreement or the 280G payments. OTHER MATTERS The Board of Directors of Mercantile is not aware of any business to come before the special meeting other than those matters described above in this proxy statement-prospectus. If, however, any other matters not now known should properly come before the special meeting, the proxy holders named in the accompanying proxy will vote such proxy on such matters as determined by a majority of the Board of Directors of Mercantile.

The Resulting Corporation on the Effective Date, and without any order or other action on the part of any court or otherwise, shall hold and enjoy all rights of property, franchises and interests, including appointments, designations and nominations and all other rights and interests as trustee, executor, administrator, transfer agent and registrar of stocks and bonds, A-5 guardian of estates, assignee, and receiver and in every other fiduciary capacity and in every agency, and capacity, in the same manner and to the same extent as such rights, franchises and interests were held or enjoyed by Acquired Corporation and BancGroup, respectively, on the Effective Date. At and after the Effective Date, the Merger shall also have the effects set forth in Section 5.07 of the TBCA. 2.3 Certificate of Incorporation and Bylaws. On the Effective Date, the certificate of incorporation and bylaws of the Resulting Corporation shall be the restated certificate of incorporation, as amended, and bylaws of BancGroup as they exist immediately before the Effective Date. 2.4 Resulting Corporation's Officers and Board. The board of directors and the officers of the Resulting Corporation on the Effective Date shall consist of those persons serving in such capacities of BancGroup as of the Effective Date. 2.5 Shareholder Approval. This Agreement shall be submitted to the shareholders of Acquired Corporation at a special or annual meeting of Acquired Corporation's shareholders (the "Shareholders Meeting") to be held as promptly as practicable consistent with the satisfaction of the conditions set forth in this Agreement. Upon approval by the requisite vote of the shareholders of Acquired Corporation as required by applicable Law, the Merger shall become effective as soon as practicable thereafter in the manner provided in Section 2.7 hereof. 2.6 Further Acts. If, at any time after the Effective Date, the Resulting Corporation shall consider or be advised that any further assignments or assurances in law or any other acts are necessary or desirable (i) to vest, perfect, confirm or record, in the Resulting Corporation, title to and possession of any property or right of Acquired Corporation or BancGroup, acquired as a result of the Merger, or (ii) otherwise to carry out the purposes of this Agreement, BancGroup and its officers and directors shall execute and deliver all such proper deeds, assignments and assurances in law and do all acts necessary or proper to vest, perfect or confirm title to, and possession of, such property or rights in the Resulting Corporation and otherwise to carry out the purposes of this Agreement; and the proper officers and directors of the Resulting Corporation are fully authorized in the name of Acquired Corporation or BancGroup, or otherwise, to take any and all such action. 2.7 Effective Date and Closing. Subject to the terms of all requirements of Law and the conditions specified in this Agreement, the Merger shall become effective on the date specified in the Certificate of Merger to be filed with the Secretary of State of the State of Delaware (such time being herein called the "Effective Date"), which shall be the date of the Closing unless the parties otherwise agree. Assuming all other conditions stated in this Agreement have been or will be satisfied as of the Closing, the Closing shall take place at the offices of BancGroup, in Montgomery, Alabama, at 5:00 p.m. on a date agreed to by Acquired Corporation and BancGroup that shall be as soon as reasonably practicable after the later to occur of (i) the Shareholders Meeting, (ii) receipt of all required regulatory approvals under Section 8.2, and satisfaction of all other conditions precedent set forth in Articles 8 and 9, which are required to be satisfied prior to Closing, or at such other place and time that the Parties may mutually agree. 2.8 Subsidiary Bank Merger. BancGroup and Acquired Corporation anticipate that on or after the Effective Date, the Bank will merge with and into Colonial Bank ("the Bank Merger"). The exact timing and structure of the Bank Merger has not been finalized at this time, and BancGroup in its sole discretion will finalize such timing and structure at a later date, including whether the Bank shall be merged into Colonial Bank ("Resulting Bank"), provided, however, the Bank Merger will be structured such that it will not have a negative impact on the fax consequences of the Merger to the Acquired Corporation Shareholders and will not materially delay the consummation of the Merger. Acquired Corporation, as sole shareholder of Mercantile Delaware Bancorp, Inc. ("MDBI"), a Delaware corporation, which is the sole shareholder of Bank, will cause all necessary steps be taken to consummate the Bank Merger, including the calling of any special meetings of the board of directors or shareholders of the Bank, voting its shares of stock of the Bank in favor of the Bank Merger and the filing of any regulatory applications. A-6 ARTICLE 3 CONVERSION OF ACQUIRED CORPORATION STOCK 3.1 Conversion of Acquired Corporation Stock. (a) On the Effective Date, each share of common stock, $5.00 par value, of Acquired Corporation outstanding and held of record by Acquired Corporation's shareholders (the "Acquired Corporation Stock"), shall be converted by operation of law and without any action by any holder thereof into shares of BancGroup Common Stock (as defined in Section 14). Specifically, each outstanding share of Acquired Corporation Stock shall (subject to Section 3.3 hereof), be converted into 3.4808 shares of BancGroup Common Stock (the "Exchange Ratio"), provided that the Market Value for BancGroup Common Stock is not less than $11.00 per share nor greater than $15.00 per share. If Market Value is less than $11.00, the Exchange Ratio shall equal $38.29 divided by the Market Value of BancGroup Common Stock (rounded to the nearest one-thousandth). If the Market Value is greater than $15.00, then the Exchange Ratio shall equal $52.21 divided by the Market Value of BancGroup Common Stock (rounded to the nearest one-thousandth). The Market Value shall be the average of the closing prices of the BancGroup Common Stock as reported by the New York Stock Exchange ("NYSE") on each of the ten trading days ending on the trading day five trading days immediately preceding the Effective Date. The appropriate ratio that is used to calculate the Merger Consideration based upon the Market Value as set forth above is referred to as the "Exchange Ratio". However, if there shall be announced between the date of this Agreement and the Effective Date (i) by any Person that such Person is or has commenced a tender or exchange offer to acquire in excess of 50% of the outstanding shares of BancGroup Common Stock, or (ii) by BancGroup that it has entered into a letter of intent or an agreement for the acquisition of BancGroup by another Person or that BancGroup shall be merged with a Person in a transaction in which BancGroup is not the surviving corporation, or a transaction in which BancGroup's current shareholders would own less than 50% of the resulting corporation, then each outstanding share of Acquired Corporation Stock shall be converted into 3.4808 shares of BancGroup Common Stock without reference to the Market Value of BancGroup Common Stock. (b) (i) On the Effective Date, and subject to Section 3.1(c) below, BancGroup shall assume all Acquired Corporation Options outstanding in accordance with the applicable terms of the Acquired Corporation stock option plans ("Acquired Corporation Stock Option Plan"). Such assumption shall be in a manner consistent with the terms of the Acquired Corporation Stock Option Plan and any Acquired Corporation Stock Option agreement pursuant to which such Acquired Corporation Stock Options were issued and granted. Each such option shall cease to represent a right to acquire Acquired Corporation Stock and shall, instead, represent the right to acquire BancGroup Common Stock on substantially the same terms applicable to the Acquired Corporation Options except as specified below in this Section. The number of shares of BancGroup Common Stock to be issued pursuant to such options shall equal the number of shares of Acquired Corporation Stock subject to such Acquired Corporation Options multiplied by the Exchange Ratio, provided that no fractions of shares of BancGroup Common Stock shall be issued and the number of shares of BancGroup Common Stock to be issued upon the exercise of Acquired Corporation Options, if a fractional share exists, shall equal the number of whole shares obtained by rounding to the nearest whole number, giving account to such fraction, or by paying for such fraction in cash, based upon the Market Value. The exercise price for the acquisition of BancGroup Common Stock shall be the exercise price for each share of Acquired Corporation Stock subject to such options divided by the Exchange Ratio, adjusted appropriately for any rounding to whole shares that may be done. It is intended that the assumption by BancGroup of the Acquired Corporation Options shall be undertaken in a manner that will not constitute a "modification", "extension", or "renewal" as defined in Section 424 of the Internal Revenue Code of 1986, as amended (the "Code") as to any stock option which is an "incentive stock option." Schedule 3.1 hereto sets forth the names of all persons holding Acquired Corporation Options, the number of shares of Acquired Corporation Stock subject to such options, the exercise price and the expiration date of such options. As soon as reasonably practicable after the Effective Date, BancGroup shall deliver to each shareholder an appropriate notice setting forth such person's rights and the number of shares and the exercise price thereof of BancGroup Common Stock applicable to such option. Schedule 3.1 also contains complete and accurate copies of all Acquired Corporation's Stock Option Plans and forms of Acquired Corporation Stock Option Agreements used, and the most recent prospectus sent to stock option holders, if applicable. A-7 (ii) BancGroup shall file at its expense a registration statement with the SEC on Form S-8 or such other appropriate form (including the Form S-4 to be filed in connection with the Merger) with respect to the shares of BancGroup Common Stock to be issued pursuant to such options and shall use its reasonable best efforts to maintain the effectiveness of such registration statement for so long as such options remain outstanding. Such shares shall also be registered or qualified for sale under the securities laws of any state in which registration or qualification is necessary. (c) In lieu of the conversion specified in paragraph (b)(i) of Section 3, no later than five days prior to the Effective Date, each holder of outstanding Acquired Corporation Options may provide written notice to Acquired Corporation (in form and substance reasonably satisfactory to BancGroup) that he or she wishes to exchange his or her Acquired Corporation Options, as of the Effective Date, and, to receive an amount of BancGroup Common Stock or cash, in exchange therefor. The amount of cash to be received shall be determined by calculating the difference between (i) the number obtained by multiplying the number of shares of Acquired Corporation Stock issuable pursuant to his or her Acquired Corporation Options times the Exchange Ratio times Market Value and (ii) the number obtained by multiplying the number of shares of Acquired Corporation Stock issuable pursuant to his or her Acquired Corporation Options times the exercise price per share (as determined pursuant to the applicable stock option plan and stock option agreement of the Acquired Corporation) (such difference is referred to herein as the "Option Consideration"). If the holder of Acquired Corporation Options elects to receive BancGroup Common Stock in lieu of cash, the Option Consideration shall be divided by Market Value to determine the number of shares of BancGroup Common Stock to be received. In the event that the exercise prices of all Acquired Corporation Options are not the same, The Option Consideration shall be determined for each series of options and the number of shares of BancGroup Common Stock issued shall be totaled to obtain the aggregate number of shares to be received by that holder of such Acquired Corporation Options. No fractional shares shall be issued and fractions shall be paid in cash at the Market Value. If an Acquired Corporation Company Employee chooses to exchange his or her options in accordance with this Section 3.1(c), he or she shall also receive a cash bonus equal to the Option Consideration multiplied by 0.34 less any consideration due such Acquired Corporation Company Employee under any "Tax Gross Up Bonus" or any other bonus related in any way to the exercise of the Acquired Corporation Options. If less than all such options are exchanged the bonus shall be reduced pro rata for those options not exchanged. For example, if an individual who holds 100 options of a particular class as of the Effective Date and whose bonus set out on Schedule 3.1(c) is $1,000, elects to exchange 80 options pursuant to this Section 3.1(c) (leaving 20 options remaining); then such individual's bonus shall be $800 (800/100 x $100). 3.2 Surrender of Acquired Corporation Stock. After the Effective Date, each holder of an outstanding certificate or certificates which represented shares of Acquired Corporation Stock who is entitled to receive BancGroup Common Stock shall be entitled, upon surrender to BancGroup or an exchange agent appointed by BancGroup, of their certificate or certificates representing shares of Acquired Corporation Stock (or an affidavit or affirmation by such holder of the loss, theft, or destruction of such certificate or certificates in such form as BancGroup may reasonably require and, if BancGroup reasonably requires, a bond of indemnity in form and amount, and issued by such sureties, as BancGroup may reasonably require), to receive in exchange therefor a certificate or certificates representing the number of whole shares of BancGroup Common Stock into and for which the shares of Acquired Corporation Stock so surrendered shall have been converted, such certificates to be of such denominations and registered in such names as such holder may reasonably request. Such holder shall receive cash for fractional shares. Until so surrendered and exchanged, each such outstanding certificate which, prior to the Effective Date, represented shares of Acquired Corporation Stock and which is to be converted into BancGroup Common Stock shall for all purposes evidence ownership of the BancGroup Common Stock into and for which such shares shall have been so converted, except that no dividends or other distributions with respect to such BancGroup Common Stock shall be made until the certificates previously representing shares of Acquired Corporation Stock shall have been properly tendered, but upon surrender such dividends and distributions shall be paid (without interest). Within a reasonable time after the Effective Date the Exchange Agent shall send a notice and transmittal form to each Acquired Corporation shareholder advising as to the effectiveness of the Merger and the procedure for exchange of stock certificates. A-8 3.3 Fractional Shares. No fractional shares of BancGroup Common Stock shall be issued, and each holder of shares of Acquired Corporation Stock having a fractional interest arising upon the conversion of such shares into shares of BancGroup Common Stock shall, at the time of surrender of the certificates previously representing Acquired Corporation Stock, be paid by BancGroup an amount in cash equal to the Market Value of such fractional share. 3.4 Adjustments. In the event that, prior to the Effective Date, BancGroup Common Stock shall be changed into a different number of shares or a different class of shares by reason of any recapitalization or reclassification, stock dividend, combination, stock split, or reverse stock split of the BancGroup Common Stock, or changed into or exchanged for a different kind or number of securities, then an appropriate and proportionate adjustment shall be made in the number of shares of BancGroup Common Stock (or such other company the shares of BancGroup Common Stock shall have been changed or exchanged for) into which the Acquired Corporation Stock shall be converted. Appropriate and proportionate adjustments shall also be made in the maximum and minimum Exchange Ratios set forth in this Agreement. 3.5 BancGroup Stock. The shares of BancGroup Common Stock issued and outstanding immediately before the Effective Date shall continue to be issued and outstanding shares of the Resulting Corporation. 3.6 Dissenting Rights. Any shareholder of Acquired Corporation who shall not have voted in favor of this Agreement and who has complied with the applicable procedures set forth in the TBCA, relating to rights of dissenting shareholders, shall be entitled to receive payment for the fair value of his Acquired Corporation Stock. If after the Effective Date a dissenting shareholder of Acquired Corporation fails to perfect, or effectively withdraws or loses his right to appraisal and payment for his shares of Acquired Corporation Stock, BancGroup shall issue and deliver the consideration to which such holder of shares of Acquired Corporation Stock is entitled under Section 3.1 (without interest) upon surrender by such holder of the certificate or certificates representing shares of Acquired Corporation Stock held by him or her.

All of the foregoing financial statements are in all material respects in accordance with the books and records of Acquired Corporation and have been prepared in accordance with GAAP applied on a consistent basis throughout the periods indicated, except for changes required by GAAP, all as more particularly set forth in the notes to such statements. Each of such balance sheets presents fairly as of its date the financial condition of Acquired Corporation. Except as and to the extent reflected or reserved against in such balance sheets (including the notes thereto), Acquired Corporation did not have, as of the date of such balance sheets, any material Liabilities or obligations (absolute or contingent) of a nature customarily reflected in a balance sheet or the notes thereto. The statements of income, shareholders equity and cash flows present fairly the results of operation, changes in shareholders equity and cash flows of Acquired Corporation for the periods indicated. The financial information contained in the above statements for the years ended December 31, 1999 and 2000, has been audited by the independent auditor for Acquired Corporation. The foregoing representations, insofar as they relate to the unaudited interim financial statements of Acquired Corporation for the nine months ended September 30, 2001, are subject in all cases to normal recurring year-end adjustments and the omission of footnote disclosure. (b) Except as set forth on Schedule 5.4(b), all Tax returns required to be filed by or on behalf of Acquired Corporation have been timely filed (or requests for extensions therefor have been timely filed and granted and have not expired), and all returns filed are complete and accurate in all material respects. All Taxes shown on these returns to be due and all additional assessments received have been paid. The amounts recorded for Taxes on the balance sheets provided under Section 5.4(a) are, to the Knowledge of Acquired Corporation, sufficient in all material respects for the payment of all unpaid federal, state, county, local, foreign and other Taxes (including any interest or penalties) of Acquired Corporation accrued for or applicable to the period ended on the dates thereof, and all years and periods prior thereto and for which Acquired Corporation may at such dates have been liable in its own right or as a transferee of the Assets of, or as successor to, any other corporation or other party. No audit, examination or investigation is presently being conducted or, to the Knowledge of Acquired Corporation, threatened by any taxing authority which is likely to result in a material Tax Liability, no material unpaid Tax deficiencies or additional liability of any sort has been proposed by any governmental representative and no agreements for extension of time for the assessment of any material amount of Tax have been entered into by or on behalf of Acquired Corporation. Acquired Corporation has not executed an extension or waiver of any statute of limitations on the assessment or collection of any Tax due that is currently in effect. A-14 (c) Each Acquired Corporation Company has withheld from its employees (and timely paid to the appropriate governmental entity) proper and accurate amounts for all periods in material compliance with all Tax withholding provisions of applicable federal, state, foreign and local Laws (including without limitation, income, social security and employment Tax withholding for all types of compensation). Each Acquired Corporation Company is in compliance with, and its records contain all information and documents (including properly completed IRS Forms W-9) necessary to comply with, all applicable information reporting and Tax withholding requirements under federal, state and local Tax Laws, and such records identify with specificity all accounts subject to backup withholding under Section 3406 of the Code. 5.5 Absence of Certain Changes or Events. Except as set forth on Schedule 5.5, since the date of the most recent balance sheet provided under Section 5.4(a)(i) above, no Acquired Corporation Company has: (a) issued, delivered or agreed to issue or deliver any stock or other corporate equity securities (whether authorized and unissued or held in the treasury) except shares of common stock issued upon the exercise of existing Acquired Corporation Options and shares issued as director's qualifying shares; (b) borrowed or agreed to borrow any funds or incurred, or become subject to, any Liability (absolute or contingent) except borrowings, obligations (including purchase of federal funds) and Liabilities incurred in the ordinary course of business and consistent with past practice; (c) paid any material obligation or Liability (absolute or contingent) other than current Liabilities reflected in or shown on the most recent balance sheet referred to in Section 5.4(a)(i) and current Liabilities incurred since that date in the ordinary course of business and consistent with past practice; (d) declared or made, or agreed to declare or make, any payment of dividends or distributions of any Assets of any kind whatsoever to shareholders, or purchased or redeemed, or agreed to purchase or redeem, directly or indirectly, or otherwise acquire, any of its outstanding securities. In no event shall the shareholders of Acquired Corporation be entitled to both an Acquired Corporation dividend and to BancGroup's regular dividend during the quarter in which the Effective Date occurs. Notwithstanding the foregoing, nothing in this Agreement shall prevent the Bank and MDBI from paying dividends to the Acquired Corporation in such amount necessary for the Acquired Corporation to make any interest payments on its debentures or other indebtedness outstanding as of the date of this Agreement. Provided, further, that in the event the Merger does not close prior to the record date for the second quarter dividend at BancGroup (such dividend generally being declared in the July meeting of the board of directors of BancGroup), the Acquired Corporation may pay a dividend to its Shareholders in an amount equal to the amount of dividend such Shareholders would have received if they were shareholders of BancGroup on such record date. For purposes of determining the amount of such dividend the Acquired Corporation may use the exchange ratio of 3.4808 in calculating the number of shares of BancGroup Common Stock that would have been received by the Shareholders. (e) except in the ordinary course of business, sold or transferred, or agreed to sell or transfer, any of its Assets, or canceled, or agreed to cancel, any debts or claims; (f) except in the ordinary course of business, entered or agreed to enter into any agreement or arrangement granting any preferential rights to purchase any of its Assets, or requiring the consent of any party to the transfer and assignment of any of its Assets; (g) suffered any Losses or waived any rights of value which in either event in the aggregate would have a Material Adverse Effect on Acquired Corporation considering its business as a whole; (h) except in the ordinary course of business, made or permitted any amendment or termination of any Contract, agreement or license to which it is a party if such amendment or termination would have a Material Adverse Effect on Acquired Corporation considering its business as a whole; A-15 (i) except as set forth in Schedule 5.5(i) or in accordance with normal and usual practice, and as previously disclosed to BancGroup, made any accrual or arrangement for or payment of bonuses or special compensation of any kind or any severance or termination pay to any present or former officer or employee; (j) except in accordance with normal and usual practice, and as previously disclosed to BancGroup, increased the rate of compensation payable to or to become payable to any of its officers or employees or made any material increase in any profit sharing, bonus, deferred compensation, savings, insurance, pension, retirement or other employee benefit plan, payment or arrangement made to, for or with any of its officers or employees; (k) received notice or had Knowledge or reason to believe that any of its substantial customers has terminated or intends to terminate its relationship, which termination would have a Material Adverse Effect on its financial condition, results of operations, business, Assets or properties; (l) failed to operate its business in the ordinary course so as to preserve its business intact and to preserve the goodwill of its customers and others with whom it has business relations; (m) other than this Agreement and the Stock Option Agreement, entered into any material transaction other than in the ordinary course of business; or (n) agreed in writing, or otherwise, to take any action described in clauses (a) through (m) above. Between the date hereof and the Effective Date, no Acquired Corporation Company, without the express written approval of BancGroup, will do any of the things listed in clauses (a) through (n) of this Section 5.5 except as permitted therein or as contemplated in this Agreement, and no Acquired Corporation Company will enter into or amend any material Contract, other than Loans or renewals thereof entered into in the ordinary course of business, without the express written consent of BancGroup. 5.6 Title and Related Matters.

Except as set out in Schedule 5.9, there is no Litigation (whether or not purportedly on behalf of Acquired Corporation) pending or, to the Knowledge of Acquired Corporation, threatened against or affecting any Acquired Corporation Company (nor does Acquired Corporation have Knowledge of any facts which are likely to give rise to any such Litigation) at law or in equity, or before or by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, or before any arbitrator of any kind, which involves the reasonable likelihood of any judgment or Liability not fully covered by insurance in excess of a reasonable deductible amount or which may have a Material Adverse Effect on Acquired Corporation, and no Acquired Corporation Company is in Default with respect to any judgment, order, writ, injunction, decree, award, rule or regulation of any court, arbitrator or governmental department, commission, board, bureau, agency or instrumentality, which Default would have a Material Adverse Effect on Acquired Corporation.

Acquired Corporation shall contact any person who may be required to execute an undertaking under Section 10.5 hereof to request such undertaking and shall take all such reasonable steps as are necessary to obtain such undertaking. Acquired Corporation will take no action that would prevent or impede the Merger from qualifying as a tax-free reorganization within the meaning of Section 368 of the Code.

(b) Stockholders Meeting; Best Efforts. Acquired Corporation will cooperate with BancGroup in the preparation of the Registration Statement (which shall include the prospectus/proxy statement for the Shareholder Meeting) and any regulatory filings and will cause the Shareholders Meeting to be held for the purpose of approving the Merger as soon as practicable after the effective date of the Registration Statement, and will use commercially reasonable efforts (subject to compliance with their fiduciary duties) to bring about the transactions contemplated by this Agreement, including shareholder approval of this Agreement, as soon as practicable unless this Agreement is terminated as provided herein. (c) Prohibited Negotiations. (i) Except with respect to this Agreement and the transactions contemplated hereby, no Acquired Corporation Company nor any affiliate thereof nor any investment banker, attorney, accountant, or other representative (collectively, "Representatives") retained by an Acquired Corporation Company shall directly or indirectly solicit any Acquisition Proposal by any Person. Except to the extent deemed necessary to comply with the fiduciary duties of Acquired Corporation's board of directors under applicable law (based on the written advice by counsel to such board of directors that failure to do so may constitute a breach of their fiduciary duties), no Acquired Corporation Company or any Representative thereof shall furnish any non-public information that it is not legally obligated to furnish, negotiate with respect to, or enter into any Contract with respect to, any Acquisition Proposal, and each Acquired Corporation Company shall direct and use its reasonable efforts to cause all of its Representatives not to engage in any of the foregoing, but Acquired Corporation may communicate information about such an Acquisition Proposal to its shareholders if and to the extent that such action is based on the written advice at counsel to such board of directors that failure to do so may constitute a breach of their fiduciary duties under applicable law. Acquired Corporation shall promptly notify BancGroup orally and in writing in the event that any Acquired Corporation Company receives any inquiry or proposal relating to any such Acquisition Proposal. Acquired Corporation shall immediately cease and cause to be terminated any existing activities, discussions, or negotiations with any Persons other than BancGroup conducted heretofore with respect to any of the foregoing.

If the action is effected and the shareholder shall not have voted in favor of the action, the corporation, in the case of action other than a merger, or the surviving or new corporation (foreign or domestic) or other entity that is liable to discharge the shareholder's right of dissent, in the case of a merger, shall, within ten (10) days after the action is effected, deliver or mail to the shareholder written notice that the action has been effected, and the shareholder may, within ten (10) days from the delivery or mailing of the notice, make written demand on the existing, surviving, B-1 or new corporation (foreign or domestic) or other entity, as the case may be, for payment of the fair value of the shareholder's shares. The fair value of the shares shall be the value thereof as of the day immediately preceding the meeting, excluding any appreciation or depreciation in anticipation of the proposed action.

The notice shall be accompanied by a copy of this Article and any articles or documents filed by the corporation with the Secretary of State to effect the action. If the shareholder shall not have consented to the taking of the action, the shareholder may, within twenty (20) days after the mailing of the notice, make written demand on the existing, surviving or new corporation (foreign or domestic) or other entity, as the case may be, for payment of the fair value of the shareholder's shares. The fair value of the shares shall be the value thereof as of the date the written consent authorizing the action was delivered to the corporation pursuant to Section A of Article 9.10 of this Act, excluding any appreciation or depreciation in anticipation of the action. The demand shall state the number and class of shares owned by the dissenting shareholder and the fair value of the shares as estimated by the shareholder. Any shareholder failing to make demand within the twenty (20) day period shall be bound by the action. (2) Within twenty (20) days after receipt by the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, of a demand for payment made by a dissenting shareholder in accordance with Subsection (1) of this Section, the corporation (foreign or domestic) or other entity shall deliver or mail to the shareholder a written notice that shall either set out that the corporation (foreign or domestic) or other entity accepts the amount claimed in the demand and agrees to pay that amount within ninety (90) days after the date on which the action was effected, and, in the case of shares represented by certificates, upon the surrender of the certificates duly endorsed, or shall contain an estimate by the corporation (foreign or domestic) or other entity of the fair value of the shares, together with an offer to pay the amount of that estimate within ninety (90) days after the date on which the action was effected, upon receipt of notice within sixty (60) days after that date from the shareholder that the shareholder agrees to accept that amount and, in the case of shares represented by certificates, upon the surrender of the certificates duly endorsed. (3) If, within sixty (60) days after the date on which the corporate action was effected, the value of the shares is agreed upon between the shareholder and the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, payment for the shares shall be made within ninety (90) days after the date on which the action was effected and, in the case of shares represented by certificates, upon surrender of the certificates duly endorsed. Upon payment of the agreed value, the shareholder shall cease to have any interest in the shares or in the corporation. B. If, within the period of sixty (60) days after the date on which the corporate action was effected, the shareholder and the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, do not so agree, then the shareholder or the corporation (foreign or domestic) or other entity may, within sixty (60) days after the expiration of the sixty (60) day period, file a petition in any court of competent jurisdiction in the county in which the principal office of the domestic corporation is located, asking for a finding and determination of the fair value of the shareholder's shares. Upon the filing of any such petition by the shareholder, service of a copy thereof shall be made upon the corporation (foreign or domestic) or other entity, which shall, within ten (10) days after service, file in the office of the clerk of the court in which the petition was filed a list containing the names and addresses of all shareholders of the domestic corporation who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the corporation (foreign or domestic) or other entity. If the petition shall be filed by the corporation B-2 (foreign or domestic) or other entity, the petition shall be accompanied by such a list. The clerk of the court shall give notice of the time and place fixed for the hearing of the petition by registered mail to the corporation (foreign or domestic) or other entity and to the shareholders named on the list at the addresses therein stated. The forms of the notices by mail shall be approved by the court. All shareholders thus notified and the corporation (foreign or domestic) or other entity shall thereafter be bound by the final judgment of the court. C. After the hearing of the petition, the court shall determine the shareholders who have complied with the provisions of this Article and have become entitled to the valuation of and payment for their shares, and shall appoint one or more qualified appraisers to determine that value. The appraisers shall have power to examine any of the books and records of the corporation the shares of which they are charged with the duty of valuing, and they shall make a determination of the fair value of the shares upon such investigation as to them may seem proper. The appraisers shall also afford a reasonable opportunity to the parties interested to submit to them pertinent evidence as to the value of the shares. The appraisers shall also have such power and authority as may be conferred on Masters in Chancery by the Rules of Civil Procedure or by the order of their appointment. D. The appraisers shall determine the fair value of the shares of the shareholders adjudged by the court to be entitled to payment for their shares and shall file their report of that value in the office of the clerk of the court. Notice of the filing of the report shall be given by the clerk to the parties in interest. The report shall be subject to exceptions to be heard before the court both upon the law and the facts. The court shall by its judgment determine the fair value of the shares of the shareholders entitled to payment for their shares and shall direct the payment of that value by the existing, surviving, or new corporation (foreign or domestic) or other entity, together with interest thereon, beginning 91 days after the date on which the applicable corporate action from which the shareholder elected to dissent was effected to the date of such judgment, to the shareholders entitled to payment. The judgment shall be payable to the holders of uncertificated shares immediately but to the holders of shares represented by certificates only upon, and simultaneously with, the surrender to the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, of duly endorsed certificates for those shares. Upon payment of the judgment, the dissenting shareholders shall cease to have any interest in those shares or in the corporation. The court shall allow the appraisers a reasonable fee as court costs, and all court costs shall be allotted between the parties in the manner that the court determines to be fair and equitable. E. Shares acquired by the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, pursuant to the payment of the agreed value of the shares or pursuant to payment of the judgment entered for the value of the shares, as in this Article provided, shall, in the case of a merger, be treated as provided in the plan of merger and, in all other cases, may be held and disposed of by the corporation as in the case of other treasury shares. F. The provisions of this article shall not apply to a merger if, on the date of the filing of the articles of merger, the surviving corporation is the owner of all the outstanding shares of the other corporations, domestic or foreign, that are parties to the merger. G. In the absence of fraud in the transaction, the remedy provided by this Article to a shareholder objecting to any corporate action referred to in Article 5.11 of this Act is the exclusive remedy for the recovery of the value of his shares or money damages to the shareholder with respect to the action. If the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, complies with the requirements of this Article, any shareholder who fails to comply with the requirements of this Article shall not be entitled to bring suit for the recovery of the value of his shares or money damages to the shareholder with respect to the action. Art. 5.13 Provisions Affecting Remedies of Dissenting Shareholders A. Any shareholder who has demanded payment for his shares in accordance with either Article 5.12 or 5.16 of this Act shall not thereafter be entitled to vote or exercise any other rights of a shareholder except the right to receive payment for his shares pursuant to the provisions of those articles and the right to maintain an appropriate action to obtain relief on the ground that the corporate action would be or was fraudulent, and the respective shares for which payment has been demanded shall not thereafter be considered outstanding for the purposes of any subsequent vote of shareholders. B-3 B. Upon receiving a demand for payment from any dissenting shareholder, the corporation shall make an appropriate notation thereof in its shareholder records. Within twenty (20) days after demanding payment for his shares in accordance with either Article 5.12 or 5.16 of this Act, each holder of certificates representing shares so demanding payment shall submit such certificates to the corporation for notation thereon that such demand has been made. The failure of holders of certificated shares to do so shall, at the option of the corporation, terminate such shareholder's rights under Articles 5.12 and 5.16 of this Act unless a court of competent jurisdiction for good and sufficient cause shown shall otherwise direct. If uncertificated shares for which payment has been demanded or shares represented by a certificate on which notation has been so made shall be transferred, any new certificate issued therefor shall bear similar notation together with the name of the original dissenting holder of such shares and a transferee of such shares shall acquire by such transfer no rights in the corporation other than those which the original dissenting shareholder had after making demand for payment of the fair value thereof. C. Any shareholder who has demanded payment for his shares in accordance with either Article 5.12 or 5.16 of this Act may withdraw such demand at any time before payment for his shares or before any petition has been filed pursuant to Article 5.12 or 5.16 of this Act asking for a finding and determination of the fair value of such shares, but no such demand may be withdrawn after such payment has been made or, unless the corporation shall consent thereto, after any such petition has been filed. If, however, such demand shall be withdrawn as hereinbefore provided, or if pursuant to Section B of this Article the corporation shall terminate the shareholder's rights under Article 5.12 or 5.16 of this Act, as the case may be, or if no petition asking for a finding and determination of fair value of such shares by a court shall have been filed within the time provided in Article 5.12 or 5.16 of this Act, as the case may be, or if after the hearing of a petition filed pursuant to Article 5.12 or 5.16, the court shall determine that such shareholder is not entitled to the relief provided by those articles, then, in any such case, such shareholder and all persons claiming under him shall be conclusively presumed to have approved and ratified the corporate action from which he dissented and shall be bound thereby, the right of such shareholder to be paid the fair value of his shares shall cease, and his status as a shareholder shall be restored without prejudice to any corporate proceedings which may have been taken during the interim, and such shareholder shall be entitled to receive any dividends or other distributions made to shareholders in the interim. B-4 APPENDIX C ______________, 2002 The Board of Directors Mercantile Bancorp, Inc. 8144 Walnut Hill Lane, Suite 172 Dallas, Texas 75231 Attn: Mr. Roy J. Salley, President & CEO Members of the Board: We understand that Mercantile Bancorp, Inc. ("MBI"), a Texas Corporation, and The Colonial BancGroup, Inc., a Delaware corporation ("BancGroup"), have entered into an Agreement and Plan of Reorganization (the "Reorganization Agreement") dated November 29, 2001, which provides for the merger (the "Merger") of MBI with and into BancGroup. Pursuant to the terms of the Reorganization Agreement, each issued and outstanding share of common stock, par value $5.00 per share, of MBI, as of the date the Merger becomes effective (the "Effective Date"), will be converted into the right to receive 3.4808 shares of BancGroup common stock, subject to adjustment as described in the Reorganization Agreement (the "Exchange Ratio"). The terms and conditions of the Merger are more fully set forth in the Reorganization Agreement. You have asked for our opinion ("Opinion"), as independent financial advisors, as to whether the Exchange Ratio, as set forth in the Reorganization Agreement, is fair from a financial point of view, to holders of MBI common stock. Our Opinion is based on information furnished to us by MBI and BancGroup, their accountants, or obtained by us from published and other sources we consider relevant. We have relied upon and assumed the accuracy and completeness of all information submitted to us or that was publicly available and have made no independent verification of this information. We have not conducted any valuation or appraisal of any assets or liabilities, nor have any such valuations or appraisals been provided to us. In relying upon financial analyses and forecasts provided to us, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management of MBI and BancGroup as to the expected future results of operations and financial condition of MBI and BancGroup to which such analyses or forecasts relate. We have relied as to all legal matters relevant to rendering our Opinion upon the advice of our counsel. MBI and BancGroup 's management have informed us that they know of no additional information that would have a material effect upon our Opinion. In arriving at our Opinion, we have followed generally accepted industry practices for the valuation of commercial banks and have used such valuation methodologies as we have deemed necessary or appropriate for the purposes of this Opinion. We have given consideration to all available financial data and other relevant factors affecting fair value including, but not limited to the following, (i) certain publicly available financial statements and other information of MBI and BancGroup, including but not limited to the September 30, 2001 Regulatory Call Report of First Mercantile Bank, N.A. (the "Bank"), FRY-9C Consolidated Financial Reports of MBI and Form 10Q (Quarterly Report) of BancGroup, (ii) certain internal financial statements and other financial and operating data concerning MBI and BancGroup prepared by the management of MBI and BancGroup, respectively, (iii) certain summary financial projections concerning MBI and BancGroup prepared by the management of MBI and BancGroup, respectively; (iv) discussions with senior executives of MBI regarding the past and current operations and prospects of MBI, (v) discussions with senior executives of BancGroup regarding the past and current operations and financial condition and the prospects of BancGroup, (vi) discussions with senior executives of MBI and BancGroup as to the strategic objectives of the Merger and the long term benefits expected to result from the Merger, including without limitation, certain estimates C-1 and timing of synergies and other cost savings for the continued company, (vii) reported prices and trading activity for transactions in MBI stock and BancGroup stock, (viii) the financial performance of MBI and BancGroup and the prices and trading activity of MBI and BancGroup with that of certain other comparable publicly traded companies and their securities, (ix) the financial terms, to the extent publicly available, of certain comparable transactions, (x) the Reorganization Agreement and certain related documents, and (xi) such other factors as we have deemed appropriate. Over the past two years, SAMCO Capital Markets ("SAMCO") has been engaged by MBI to provide various financial advisory services, including rendering a fairness opinion for the Company's acquisition of TownBank, NA. SAMCO also served as placement agent for MBI's $8 million Trust Preferred Securities offering. We were requested to, and did, solicit third party offers to acquire all or any part of MBI. Neither SAMCO nor the individuals involved in this valuation have any present or contemplated future financial interest in MBI or BancGroup which might prevent them from rendering a fair and unbiased Opinion. Our Opinion is necessarily based upon the business, market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter, and does not address MBI's underlying business decision to enter into the Reorganization Agreement or constitute any recommendations to any holder of common stock of MBI as to how such holder should vote with respect to the Reorganization Agreement. In reaching our Opinion, we have assumed that the Merger will be consummated in accordance with the terms described in the Reorganization Agreement. Based on the foregoing and in consideration of all relevant factors, it is our Opinion, as of the date of this letter, that the Exchange Ratio is fair, from a financial point of view, to all holders of MBI common stock. We consent to the reference to our firm and the inclusion of our Opinion in its entirety in any filing with the Securities and Exchange Commission related to the Merger and the Proxy Statement - Prospectus sent to MBI Shareholders. SAMCO Capital Markets appreciates the opportunity to be of service to you in this matter. Very truly yours, SAMCO Capital Markets By: _________________________________________________________________ Dory A. Wiley, CPA, CVA, CFA C-2 PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 20. Indemnification of Directors and Officers. Pursuant to section 145 of the Delaware General Corporation Law, as amended, and the Restated Certificate of Incorporation of the Registrant, officers, directors, employees, and agents of the Registrant are entitled to indemnification against liabilities incurred while acting in such capacities on behalf of the Registrant, including reimbursement of certain expenses. In addition, the Registrant maintains an officers and directors insurance policy pursuant to which certain officers and all directors of the Registrant are entitled to indemnification against certain liabilities, including reimbursement of certain expenses, and the Registrant has indemnity agreements ("Indemnification Agreements") with certain officers and all of its directors pursuant to which such persons may be indemnified by the Registrant against certain liabilities, including expenses. The Indemnification Agreements are intended to provide additional indemnification to directors and officers of BancGroup beyond the specific provisions of the Delaware General Corporation Law. Under the Delaware General Corporation Law, a company may indemnify its directors and officers in circumstances other than those under which indemnification and the advance of expenses are expressly permitted by applicable statutory provisions. Under the Delaware General Corporation Law, a director, officer, employee or agent of a corporation (i) must be indemnified by the corporation for all expenses incurred by him (including attorneys' fees) when he is successful on the merits or otherwise in defense of any action, suit or proceeding brought by reason of the fact that he is or was a director, officer, employee or agent of the corporation, (ii) may be indemnified by the corporation against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement of any such proceeding (other than a proceeding by or in the right of the corporation) even if he is not successful on the merits if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the corporation (and, in the case of a criminal proceeding, had no reasonable cause to believe his conduct was unlawful), and (iii) may be indemnified by the corporation for expenses (including attorneys' fees) incurred by him in the defense or settlement of a proceeding brought by or in the right of the corporation, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation; provided that no indemnification may be made under the circumstances described in clause (iii) if the director, officer, employee or agent is adjudged liable to the corporation, unless a court determines that, despite the adjudication of liability but in view of all of the circumstances, he is fairly and reasonably entitled to indemnification for the expenses which the court shall deem proper. The indemnification described in clauses (ii) and (iii) above (unless ordered by a court) may be made only as authorized in a specific case upon determination by (i) a majority of a quorum of disinterested directors, (ii) independent legal counsel in a written opinion, or (iii) the stock holders, that indemnification is proper in the circumstances because the applicable standard of conduct has been met. Expenses (including attorneys' fees) incurred by an officer or director in defending a proceeding may be advanced by the corporation prior to the final disposition of the proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay the advance if it is ultimately determined that he is not entitled to be indemnified by the corporation. Expenses (including attorneys' fees) incurred by other employees and agents may be advanced by the corporation upon terms and conditions deemed appropriate by the board of directors. The indemnification provided by the Delaware General Corporation Law has at least two limitations that are addressed by the Indemnification Agreements: (i) BancGroup is under no obligation to advance expenses to a director or officer, and (ii) except in the case of a proceeding in which a director or officer is successful on the merits or otherwise, indemnification of a director or officer is discretionary rather than mandatory. The Indemnification Agreements, therefore, cover any and all expenses (including attorneys' fees and all other charges paid or payable in connection therewith) incurred in connection with investigating, defending, being a witness or participating in (including an appeal), or preparing to defend, be a witness in or participate in, any threatened, pending or completed action, suit or proceeding, or any inquiry or investigation, whether civil, criminal, administrative or otherwise, related to the fact that such director or officer is or was a director, officer, employee or agent of BancGroup or is or was serving at the request of BancGroup as a director, officer, employee, agent, partner, committee member or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, or by reason of anything done or not done by such director or officer in any such capacity. The Indemnification Agreements also provide for the prompt advancement of all expenses incurred in connection with any proceeding and obligate the director or officer to reimburse BancGroup for all amounts so advanced if it is subsequently determined, as provided in the Indemnification Agreements, that the director or officer is not entitled to indemnification. The Indemnification Agreements further provide that the director or officer is entitled to indemnification for, and advancement of, all expenses (including attorneys' fees) incurred in any proceeding seeking to collect from BancGroup an indemnity claim or advancement of expenses under the Indemnification Agreements, BancGroup's Certificate of Incorporation, or the Delaware General Corporation Law, regardless of whether the director or officer is successful in such proceeding. The Indemnification Agreements impose upon BancGroup the burden of proving that the director or officer is not entitled to indemnification in any particular case, and the Indemnification Agreements negate certain presumptions which might otherwise be drawn against a director or officer in certain circumstances. Further, the Indemnification Agreements provide that if BancGroup pays a director or officer pursuant to an Indemnification Agreement, BancGroup will be subrogated to such director's or officer's rights to recover from third parties. The Indemnification Agreements stipulate that a director's or officer's rights under such contracts are not exclusive of any other indemnity rights a director or officer may have; however, the Indemnification Agreements prevent double payment. The Indemnification Agreements require the maintenance of directors' and officers' liability insurance if such insurance can be maintained on terms, including rates, satisfactory to BancGroup. The benefits of the Indemnification Agreements would not be available if (i) the action with respect to which indemnification is sought was initiated or brought voluntarily by the officer or director (other than an action to enforce the right to indemnification under the Indemnification Agreements); (ii) the officer or director is paid for such expense or liability under an insurance policy; (iii) the proceeding is for an accounting of profits pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended; (iv) the conduct of the officer or director is adjudged as constituting an unlawful personal benefit, or active or deliberate dishonesty or willful fraud or illegality; or (v) a court determines that indemnification or advancement of expenses is unlawful under the circumstances. The Indemnification Agreements would provide indemnification for liabilities arising under the Securities Act of 1933, as amended. BancGroup has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in such act and is, therefore, unenforceable.

Item 22. Undertakings. (a) The undersigned hereby undertakes as follows as required by Item 512 of Regulation S-K: (1) 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. (2) That every prospectus (i) that is filed pursuant to paragraph (1) immediately above, 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 Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to such securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) Insofar as indemnification for liabilities arising under the Act may be permitted to directors, officers, and controlling persons of the Registrant, 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. (b) The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, 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 documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request. (c) 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 the Registration Statement when it became effective. (d) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration 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. (3) 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. (e) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, 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 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.
