AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of June 17, 2002 (the “Agreement”), between MISSISSIPPI VALLEY BANCSHARES, INC., a Missouri corporation (the “Seller”) and ▇▇▇▇▇▇▇▇ & ILSLEY CORPORATION, a Wisconsin corporation (the “Company”).

WHEREAS, the Boards of Directors of the Company and the Seller have each determined that it is fair to and in the best interests of their respective shareholders for the Seller to merge with and into the Company (the “Merger”) upon the terms and subject to the conditions set forth herein and in accordance with The General and Business Corporation Law of Missouri (the “GBCLM”) and the Wisconsin Business Corporation Law (the “WBCL”);

WHEREAS, the respective Boards of Directors of the Company and the Seller have each approved the Merger of the Seller with and into the Company, upon the terms and subject to the conditions set forth herein, and adopted this Agreement;

WHEREAS, subsequent to the Seller’s approval of this Agreement and concurrently with the execution of this Agreement and as a condition and an inducement to the willingness of the Company to enter into this Agreement, the Company has entered into a Shareholder Voting Agreement pursuant to which each shareholder listed on Schedule I to such Shareholder Voting Agreement has agreed to vote the shares of Seller Common Stock beneficially owned by such shareholder in favor of the Merger; and

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a reorganization under the provisions of Section 368 of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement shall constitute the plan of reorganization.

NOW, THEREFORE, in consideration of the foregoing premises and the representations, warranties and agreements contained herein, and subject to the terms and conditions set forth herein, the parties hereto hereby agree as follows:

ARTICLE I—THE MERGER

SECTION 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the GBCLM, the WBCL and the Plan of Merger attached hereto as Exhibit 1.1, at the Effective Time (as defined in Section 1.2) Seller shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Seller shall cease and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”).

SECTION 1.2 The Closing; Effective Time.

(a) The closing of the Merger and the transactions contemplated hereby (the “Closing”) shall be held at such time, date and location as may be mutually agreed by the parties. In the absence of such agreement, the Closing shall be held at the offices of ▇▇▇▇▇▇▇ & ▇▇▇▇, S.C., ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, commencing at 9:00 a.m. on a date

specified by either party upon 10 business days’ written notice (or at the election of the Company on the last business day of the month) after the last to occur of the following events: (a) receipt of all consents and approvals of government regulatory authorities legally required to consummate the Merger and the expiration of all statutory waiting periods; and (b) approval of this Agreement and the Merger by the Seller’s shareholders. Scheduling or commencing the Closing shall not constitute a waiver of the conditions set forth in Article VII by either the Company or the Seller.

(b) As promptly as practicable after the Closing, the parties hereto shall cause the Merger to be consummated by filing articles of merger or summary articles of merger (the “Articles of Merger”) and any other required documents with the Secretary of State of the State of Missouri (the “Missouri Secretary of State”) and the Department of Financial Institutions of the State of Wisconsin (the “DFI”), in such form as required by, and executed in accordance with the relevant provisions of, the GBCLM and the WBCL (the date and time of such filing is referred to herein as the “Effective Time”).

SECTION 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the GBCLM and the WBCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of the Company and the Seller shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and the Seller shall become the debts, liabilities and duties of the Surviving Corporation.

SECTION 1.4 Articles of Incorporation; By–Laws. At the Effective Time, the Articles of Incorporation, as amended, of the Company (the “Company Articles”) and the By–Laws, as amended, of the Company (the “Company By–Laws”), as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation and the By–Laws of the Surviving Corporation.

SECTION 1.5 Directors and Officers. At the Effective Time, the directors of the Company immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Articles of Incorporation and By–Laws of the Surviving Corporation and to be assigned to the class previously assigned. At the Effective Time, the officers of the Company immediately prior to the Effective Time, shall be the initial officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed.

SECTION 1.6 Conversion of Securities; Dissenting Shares.

(a) Subject to Section 1.6(e) regarding fractional shares, at the Effective Time, by virtue of the Merger and without action on the part of the Company or the Seller, each share of the common stock, $1.00 par value of the Seller (“Seller Common Stock”) issued and outstanding immediately prior to the Effective Time, other than shares of Seller Common Stock held in the treasury of Seller or owned by the Company and any Company Subsidiary for its own account and other than Dissenting Shares (as defined in Section 1.6(f)) (such shares of Seller

Common Stock being referred to herein as the “Shares”), shall cease to be outstanding and shall be converted into the right to receive, at the election of the holder thereof as provided in Section 1.7, either:

(i) that number of shares of Company Common Stock which is equal to the Per Share Stock Consideration; or

(ii) cash in an amount equal to the Per Share Cash Consideration; or

(iii) $26.25 in cash and that number of shares of Company Common Stock which is equal to the product of the Per Share Stock Consideration and the Stock Percentage;

provided, however, that, the aggregate amount of cash that shall be paid in the Merger (subject to rounding) shall be equal to the product of (x) $26.25 and (y) the number of Shares (the “Cash Amount”) and the aggregate number of shares of Company Common Stock (subject to rounding) that shall be issued in the Merger shall be equal to the quotient determined by dividing (i) the Aggregate Consideration minus the Cash Amount by (ii) the Valuation Period Market Value (the “Stock Amount”).

(b) Each share of Seller Common Stock held by the Seller as treasury stock and each such share held by the Company or any Company Subsidiary immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof as otherwise provided in this Section 1.6.

(c) For purposes of this Agreement, all share exchange figures and the Valuation Period Market Values reflect the Company’s stock dividend effective with the beginning of trading on the New York Stock Exchange (the “NYSE”) on June 17, 2002 and the following definitions shall apply:

(i) “Per Share Cash Consideration” means the sum of $26.25 and an amount equal to the product of (A) the Valuation Period Market Value and (B) a number of shares of Company Common Stock (rounded to the nearest ten thousandth of a share) determined as follows:

(I) If the Valuation Period Market Value is less than $23.44, the number of shares of Company Common Stock shall be equal to 1.0116;

(II) If the Valuation Period Market Value is equal to or greater than $23.44 but less than $27.94, the number of shares of Company Common Stock shall be equal to the quotient determined by dividing $23.71 by the Valuation Period Market Value;

(III) If the Valuation Period Market Value is equal to or greater than $27.94 but less than $33.94, the number of shares of Company Common Stock shall be equal to 0.8486;

(IV) If the Valuation Period Market Value is equal to or greater than $33.94 but less than $38.44, the number of shares of Company Common Stock shall be equal to the quotient determined by dividing $28.80 by the Valuation Period Market Value; and

(V) If the Valuation Period Market Value is equal to or greater than $38.44, the number of shares of Company Common Stock shall be equal to 0.7492.

(ii) “Aggregate Consideration” means an amount equal to the product of the Shares and the Per Share Cash Consideration.

(iii) “Cash Percentage” means an amount equal to the quotient determined by dividing $26.25 by the Per Share Cash Consideration.

(iv) “Per Share Stock Consideration” means an amount equal to the quotient determined by dividing Per Share Cash Consideration by the Valuation Period Market Value.

(v) “Stock Percentage” means an amount equal to one minus the Cash Percentage.

(vi) “Valuation Period Market Value” means the average of the average daily high and low sale price per share of the Company Common Stock on the NYSE for the five (5) trading days ending on and including the third trading day preceding the Effective Time (as reported in an authoritative source).

(d) Election forms and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing Shares (“Certificates”) shall pass, only upon proper delivery of the Certificates to a bank or trust company designated by the Company (the “Exchange Agent”)) in such form as the Company and Seller shall mutually agree (“Election Forms”) shall be mailed 30 days prior to the anticipated Effective Time or on such other earlier date as Seller and Company shall mutually agree (the “Mailing Date”) to each holder of record of Shares as of five business days prior to the Mailing Date (the “Election Form Record Date”).

Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions) either (i) to elect to receive only Company Common Stock with respect to such holder’s Shares (“Stock Election Shares”); (ii) to elect to receive only cash with respect to such holder’s Shares (“Cash Election Shares”); (iii) to elect to receive Company Common Stock and cash in the proportion described in subparagraph (a) below with respect to such holder’s Shares (“Mixed Election Shares”); or (iv) to indicate that such holder makes no election (“No Election Shares”). No Election Shares shall be deemed to be Stock Election Shares.

Any Shares with respect to which the holder (or the beneficial owner, as the case may be) shall not have submitted to the Exchange Agent an effective, properly completed Election Form

on or before 5:00 p.m., New York City time, on the 27th day following the Mailing Date (or such other time and date as Company and Seller may mutually agree) (the “Election Deadline”) shall also be deemed to be “No Election Shares.”

The Company shall make available Election Forms to all persons who become holders (or beneficial owners) of Shares between the Election Form Record Date and the close of business on the business day prior to the Election Deadline, and Seller shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein.

Any such election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by one or more Certificates (or customary affidavits and indemnification regarding the loss or destruction of such Certificates or the guaranteed delivery of such Certificates) representing all Shares covered by such Election Form, together with duly executed transmittal materials included in the Election Form. Any Election Form may be revoked or changed by the person submitting such Election Form at or prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the Shares represented by such Election Form shall become No Election Shares and the Company shall cause the Certificates to be promptly returned without charge to the person submitting the Election Form upon written request to that effect from the person who submitted the Election Form. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. Neither the Company nor the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

Within three business days after the Election Deadline, unless the Effective Time has not yet occurred, in which case as soon thereafter as practicable, the Company shall cause the Exchange Agent to effect the allocation among the holders of Shares of rights to receive Company Common Stock or cash in the Merger in accordance with the Election Forms as follows:

(i) Each of the Mixed Election Shares shall be converted into a right to receive a number of shares of Company Common Stock equal to the Per Share Stock Consideration multiplied by the Stock Percentage and $26.25 in cash.

(ii) If the number of shares of Company Common Stock that would be issued upon conversion in the Merger of the Stock Election Shares and the Mixed Election Shares is less than the Stock Amount, then: (i) each of the Stock Election Shares and No Election Shares shall be converted into the right to receive a number of shares of Company Common Stock equal to the Per Share Stock Consideration, (ii) each of the Cash Election Shares will be converted into the right to receive a number of shares of Company Common Stock equal to the quotient of (m) the Stock Amount less the shares of Company Common Stock allocated pursuant to subparagraphs (a) and (b)(i) above divided by (n) the number of Cash Election Shares, plus cash in an amount equal to the

quotient of (x) the Cash Amount less the cash allocated pursuant to (a) above divided by (y) the number of Cash Election Shares.

(iii) If the number of shares of Company Common Stock that would be issued upon the conversion in the Merger of the Stock Election Shares and the Mixed Election Shares is greater than the Stock Amount, then: (i) each of the Cash Election Shares shall be converted into the right to receive cash equal to the Per Share Cash Consideration, (ii) each of the Stock Election Shares will be converted into the right to receive a number of shares of Company Common Stock equal to the quotient of (m) the Stock Amount less the shares of Company Common Stock allocated pursuant to (a) above divided by (n) the number of Stock Election Shares, plus an amount of cash equal to the quotient of (x) the Cash Amount less the amount of cash allocated pursuant to (a) and (c)(i) above divided by (y) the number of Stock Election Shares.

(e) No fractional shares of Company Common Stock shall be issued in the Merger. In lieu of a fractional share of Company Common Stock, the holder of any Shares who would otherwise be entitled to receive such fractional share shall be entitled to receive cash, without interest, in an amount determined by multiplying the Per Share Cash Consideration by the fraction of a share of Company Common Stock to which the holder would otherwise have been entitled. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional share interests, the Exchange Agent shall so notify the Company, and the Company shall deposit that amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to the holders of fractional share interests, subject to and in accordance with the terms of this Section 1.6.

(f) Notwithstanding anything in this Agreement to the contrary, shares of Seller Common Stock which are issued and outstanding immediately prior to the Effective Time and which are held by shareholders who have validly exercised dissenter’s rights available under Section 351.455 of the GBCLM (the “Dissenting Shares”) shall not be converted into or be exchangeable for the right to receive the Per Share Cash Consideration and/or Per Share Stock Consideration in accordance with this Section 1.6, unless and until such holders shall have failed to perfect or shall have effectively withdrawn or lost their dissenter’s rights under the GBCLM. Dissenting Shares shall be treated in accordance with Section 351.455 of the GBCLM, if and to the extent applicable. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right to dissent, such holder’s shares of Seller Common Stock shall thereupon be converted into and become exchangeable only for the right to receive, as of the Effective Time, the Per Share Cash Consideration and/or Per Share Stock Consideration in accordance with this Section 1.6. Seller shall give the Company (a) prompt notice of each and every notice of a shareholder’s intent to demand payment for the shareholder’s shares of Seller Common Stock, attempted withdrawals of such demands, and any other instruments served pursuant to the GBCLM and received by the Seller relating to rights to be paid the “fair value” of Dissenting Shares, as provided in Section 351.455 of the GBCLM and (b) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the GBCLM. Seller shall not, except with the prior written consent of the Company, voluntarily make any payment with respect to, offer to settle or settle, or approve any withdrawal of any demands for “fair value” under Section 351.455 of the GBCLM.

(g) If either the tax opinion referred to in Section 7.2(e) or the tax opinion referred to in Section 7.3(d) cannot be rendered because the counsel charged with providing such opinion reasonably determines that the Merger may not satisfy the continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, then the Company shall reduce the Cash Amount and correspondingly increase the Stock Amount to the minimum extent necessary to enable the relevant tax opinions to be rendered.

SECTION 1.7 Exchange of Certificates.

(a) Exchange Agent. The Company shall deposit, or shall cause to be deposited, from time to time, with the Exchange Agent, for the benefit of the holders of Shares, for exchange in accordance with this Article I, through the Exchange Agent, the Per Share Cash Consideration and/or Per Share Stock Consideration, together with any dividends or distributions with respect thereto, if any, to be issued in exchange for Shares pursuant to this Article I (the “Exchange Fund”) issuable pursuant to Section 1.6 in exchange for outstanding Shares. Such deposits shall be made after the Effective Time as requested by the Exchange Agent in order for the Exchange Agent to promptly deliver the Per Share Cash Consideration and/or Per Share Stock Consideration.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate whose Shares were converted into the right to receive the Per Share Cash Consideration and/or Per Share Stock Consideration pursuant to Section 1.6, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as the Company may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Per Share Cash Consideration and/or Per Share Stock Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Per Share Cash Consideration and/or Per Share Stock Consideration and any unpaid dividends and distributions thereon as provided in this Article I, which such holder has the right to receive in respect of the Certificate surrendered pursuant to the provisions of this Article I (after taking into account all Shares then held by such holder), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares which is not registered in the transfer records of the Seller, a transferee may exchange the Certificate representing such Shares for the Per Share Cash Consideration and/or Per Share Stock Consideration and any unpaid dividends and distributions thereon as provided in this Article I if the Certificate representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and the posting by such person of a bond in such amount as the Company may direct as indemnity against any claim that may be made against it or the Exchange Agent with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Per Share Cash Consideration and/or Per Share Stock

Consideration and any unpaid dividends and distributions thereon as provided in this Article I, which such holder would have had the right to receive in respect of such lost, stolen or destroyed Certificate. Until surrendered as contemplated by this Section 1.7, each Certificate (other than Certificates representing Shares owned by the Company or any Company Subsidiary, and Certificates representing Dissenting Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Per Share Cash Consideration and/or Per Share Stock Consideration and any unpaid dividends and distributions thereon as provided in this Article I.

(c) Distributions with Respect to Unexchanged Shares.

Neither the Seller nor any Seller Subsidiary conducts any trust operations.

(b) Seller and each Seller Subsidiary is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of its properties owned, leased or operated by it or the nature of its activities makes such qualification or licensing necessary, except for such failures to be so duly qualified or licensed and in good standing that would not, either individually or in the aggregate, have a Material Adverse Effect on Seller or Seller Subsidiaries, taken as a whole.

(c) A true and complete list of all of the Seller Subsidiaries, together with (i) the Seller’s percentage ownership of each Seller Subsidiary and (ii) laws under which the Seller Subsidiary is incorporated or organized is set forth on Annex A.

Seller and each of the Seller Subsidiaries has not incurred any liability for any excise tax arising under Sections 4971 through 4980F of the Code that would individually or in the aggregate have a Material Adverse Effect on the Seller and the Seller Subsidiaries, taken as a whole, and, to the knowledge of Seller or the Seller Subsidiaries, no fact or event exists that could give rise to any such liability.

(f) Plan Contributions. All contributions, premiums or payments required to be made with respect to any Plan have been made on or before their due dates.

(g) Employment Contracts. Except for employment, severance, consulting or other similar contracts with any employees, consultants, officers or directors of Seller or any of the Seller Subsidiaries disclosed in Section 2.10(g) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary is a party to any such contracts. Neither Seller nor any Seller Subsidiary is a party to any collective bargaining agreements.

(h) Effect of Agreement. Except as disclosed in Section 2.10(h) of the Seller Disclosure Schedule, the consummation of the transactions contemplated by this Agreement will not, either alone or in conjunction with another event, entitle any current or former employee of Seller or any Seller Subsidiary to severance pay, unemployment compensation or any other payment, except as expressly provided herein, or accelerate the time of payment or vesting or increase the compensation due any such employee or former employee, in each case, except as expressly provided herein.

SECTION 2.11 Registration Statement; Proxy Statement/Prospectus.

therein, in the light of the circumstances under which they are made, not misleading. If at any time prior to the Effective Time any event relating to Seller or any of its affiliates, officers or directors should be discovered by Seller which should be set forth in an amendment to the Registration Statement or a supplement to the Proxy Statement/Prospectus, Seller shall promptly inform the Company. The Proxy Statement/Prospectus shall comply in all material respects as to form with the requirements of the Securities Act, the Exchange Act (to the extent applicable) and the rules and regulations thereunder.

SECTION 4.5 Update Disclosure; Breaches.

(a) From and after the date of this Agreement until the Effective Time, Seller shall update the Seller Disclosure Statement on a regular basis by written notice to the Company to reflect any matters which have occurred from and after the date of this Agreement which, if existing on the date of this Agreement, would have been required to be described therein; provided that (i) to the extent that any information that would be required to be included in an update under this Section 4.5(a) would have in the past been contained in internal reports prepared by Seller or any Seller Subsidiary in the ordinary course, such update may occur by delivery of such internal reports prepared in accordance with past practice, with appropriate steps taken by Seller to identify relevant information contained therein, and (ii) to the extent that updating required under this Section is unduly burdensome to Seller, Seller and the Company will use their best efforts to develop alternate updating procedures using, wherever possible, existing reporting systems.

in favor of the Merger; provided, however, that in connection with the Seller’s Board of Directors’ recommendation to the Seller’s Shareholders in favor of a Superior Competing Transaction (as defined in Section 4.4), the Board of Directors of Seller may, at any time prior to such time as the shareholders of Seller shall have adopted and approved this Agreement and the Merger in accordance with the GBCLM, withdraw, modify or change any such recommendation to the extent Board of Directors of Seller determines in good faith, after consultation with and based upon the advice of independent legal counsel, that the failure to so withdraw, modify or change its recommendation would cause the Board of Directors of Seller to breach its fiduciary duties to Seller’s shareholders under applicable Law. Any withdrawal, modification or change of the recommendation in favor of the Merger pursuant to this Section 6.1 shall be deemed by the parties not to change the approval of the Board of Directors of Seller for purposes of causing any business combination, control share acquisition, fair price or other anti-takeover law or regulation (including, without limitation, Sections 351.407 and 351.459 of the GBCLM) to be inapplicable to the Merger and any such withdrawal, modification or change shall not affect the Seller’s obligations in the first sentence of this Section 6.1.

Seller shall give prompt notice to the Company, and the Company shall give prompt notice to Seller, of (i) the occurrence, or non-occurrence, of any event the occurrence, or non-occurrence, of which would be likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate and (ii) any failure of Seller or the Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 6.6 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

SECTION 6.7 Public Announcements.

There shall not be pending any action, proceeding or investigation before any court or administrative agency or by a government agency or any other person (i) challenging or seeking material damages in connection with, the Merger or the conversion of Seller Common Stock into Company Common Stock pursuant to the Merger or (ii) seeking to restrain, prohibit or limit the exercise of full rights of ownership or operation by the Company or the Company Subsidiaries of all or any portion of the business or assets of Seller, which in either case is reasonably likely to have a Material Adverse Effect on either Seller and the Seller Subsidiaries, taken as a whole, or the Company and the Company Subsidiaries, taken as a whole.

(e) Tax Opinion. An opinion of ▇▇▇▇▇▇▇ & ▇▇▇▇, S.C., independent counsel to the Company, dated as of the Effective Time, substantially to the effect that on the basis of facts, representations and assumptions set forth in such opinion which are consistent with the state of facts existing at the Effective Time, the Merger will be treated for federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code, and accordingly that no gain or loss will be recognized by Seller as a result of the Merger. In rendering such opinion, ▇▇▇▇▇▇▇

& ▇▇▇▇ may require and rely upon representations and covenants contained in certificates of officers of the Company, the Seller and others.

(f) Opinion of Counsel.

(h) Affiliate Agreements. The Company shall have received from each person who is identified in the affiliate letter as an “affiliate” of Seller a signed affiliate agreement in the form attached hereto as Exhibit 4.6.

(i) Burdensome Condition.

(j) No Material Adverse Changes. Since the date of the Agreement, there has been no Material Adverse Effect on the Seller or the Seller Subsidiaries, taken as a whole, and there has not been any change in the financial condition, results of operations or business of the Seller and the Seller Subsidiaries, taken as a whole, that either individually or in the aggregate would have a Material Adverse Effect on the Seller and the Seller Subsidiaries taken as a whole. The Company shall have received a certificate of the President and the Chief Financial Officer of the Seller to that effect.

(k) Seller Expenses. Seller shall have delivered to the Company evidence in form reasonably satisfactory to the Company that all out-of-pocket expenses (including, without limitation, all fees and expenses of counsel, accountants, investment bankers, experts and consultants to the Seller and its affiliates) incurred by the Seller or on its behalf in connection with or related to the authorization, preparation and execution of this Agreement, the Registration Statement and the Proxy Statement/Prospectus and all SEC and other regulatory filings, the solicitation of shareholder approvals and all other matters related to the closing of the transactions contemplated hereby are not in excess of $6,000,000.

SECTION 7.3 Additional Conditions to Obligations of Seller. The obligation of Seller to effect the Merger is also subject to the following conditions:

(a) Representations and Warranties. Each of the representations and warranties of the Company contained in this Agreement, without giving effect to any notice to Seller under Section 5.3 or 6.6 and except for Section 3.14 which is provided for in subsection (f), below, shall be true and correct in all material respects as of the date of this Agreement and (except to the extent such representations and warranties speak as of an earlier date) as of the Effective Time, as though made on and as of the Effective Time; provided, however, that for purposes of determining the satisfaction of the condition contained in this clause, no effect shall be given to any exception in such representations and warranties relating to materiality or a Material Adverse Effect, and provided, further, however, that, for purposes of this clause, such representations and warranties shall be deemed to be true and correct in all material respects unless the failure or failures of such representations and warranties to be so true and correct, individually or in the aggregate, represent a Material Adverse Effect on the Company. The Seller shall have received a certificate signed on behalf of the Company by the Chief Executive Officer and the Chief Financial Officer of the Company to the foregoing effect.

(b) Agreements and Covenants. The Company shall have performed or complied in all material respects with all agreements and covenants required by this Agreement to be performed or complied with by it on or prior to the Effective Time.

(c) Consents Obtained. All material consents, waivers, approvals, authorizations or orders required to be obtained, and all filings required to be made by the Company for the authorization, execution and delivery of this Agreement and the consummation by it of the transactions contemplated hereby shall have been obtained and made by the Company, except where the failure to obtain any consents, waivers, approvals, authorizations or orders required to be obtained or any filings required to be made would not have a Material Adverse Effect on the Company and the Company Subsidiaries, taken as a whole.

(d) Tax Opinion. The Seller shall have received an opinion of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, in form and substance reasonably satisfactory to the Seller, dated as of the Effective Time, substantially to the effect that on the basis of facts, representations and assumptions set forth in such opinion which are consistent with the state of facts existing at the Effective Time, the Merger will be treated as a reorganization within the meaning of Section 368(a) of the Code, and that, accordingly, for federal income tax purposes:

(i) No gain or loss will be recognized by the Seller as a result of the Merger;

(ii) No gain or loss will be recognized by the shareholders of the Seller who exchange their Seller Common Stock solely for Company Common Stock pursuant to the Merger (except with respect to cash received in lieu of a fractional share interest in Company Common Stock); and

(iii) The aggregate tax basis of the Company Common Stock received by shareholders who exchange their Seller Common Stock solely for Company Common Stock pursuant to the Merger will be the same as the aggregate tax basis of the Seller Common Stock surrendered in exchange therefor (reduced by any amount allocable to a fractional share interest for which cash is received).

In rendering such opinion, the Seller’s Counsel may require and rely upon representations and covenants contained in certificates of officers of Company, the Seller and others.

(e) Opinion of Counsel. Seller shall have received from ▇▇▇▇▇▇▇ & ▇▇▇▇, S.C., or other independent counsel for the Company reasonably satisfactory to Seller, opinions dated the Effective Time, in form and substance reasonably satisfactory to Seller, covering the matters set forth in Annex D hereto, which opinion shall be based on such assumptions and contain such qualifications and limitations as are appropriate and reasonably satisfactory to Seller.

The Seller shall have received a certificate of the President and the Chief Financial Officer of the Company to that effect.

(g) Employment Agreements. The Company shall have offered employment to ▇▇▇▇▇▇ ▇. ▇▇▇▇ and ▇▇▇▇ ▇. ▇▇▇▇▇▇ for the period commencing on the Effective Time and ending on December 31, 2004 and on the other terms set forth on Exhibit 7.3(g).

(i) by mutual consent of the Company and Seller by a vote of majority of the members of the entire Board of Directors of both the Company and Seller;

(ii) by Seller or the Company (A) if there has been a breach in any material respect (except that where any statement in a representation or warranty expressly includes a

standard of materiality, such statement shall have been breached in any respect) of any representation, warranty, covenant or agreement on the part of Seller, on the one hand, or the Company, on the other hand, respectively, set forth in this Agreement, or (B) if any representation or warranty of Seller, on the one hand, or the Company, on the other hand, respectively, shall be discovered to have become untrue in any material respect (except that where any statement in a representation or warranty expressly includes a standard of materiality, such statement shall have become untrue in any respect), in either case which breach or other condition has not been cured within 30 business days following receipt by the nonterminating party of notice of such breach or other condition, or which breach by its nature, cannot be cured prior to Closing; provided, however, neither party shall have the right to terminate this Agreement pursuant to this Section 8.1(a)(ii) unless the breach of any representation or warranty (but not breaches of covenants or agreements), together with all other such breaches, would entitle the party receiving such representation or warranty not to consummate the transactions contemplated hereby under Section 7.2(a) (in the case of a breach of a representation or warranty by the Seller) or Section 7.3(a) (in the case of a breach of representation or warranty by the Company); provided, further, this Agreement may not be terminated pursuant to this clause (ii) by the breaching party or party making any representation or warranty which shall have become untrue in any material respect;

(iii) by either the Company or Seller if any permanent injunction preventing the consummation of the Merger shall have become final and nonappealable;

(iv) by either the Company or Seller if the Merger shall not have been consummated by December 31, 2002, for a reason other than the failure of the party seeking termination to comply with its obligations under this Agreement; provided that if the Merger shall not have been consummated on or prior to December 31, 2002 as a result of proceedings of a governmental authority or litigation, then the date on which either the Company or the Seller may terminate this Agreement under this Section 8.1(a)(iv) shall be extended to the earlier of (A) the lapse of a reasonable period of time necessary to consummate the Merger following the final termination of proceedings of a governmental authority or litigation or (B) March 31, 2003;

(v) by either the Company or Seller if any of the Federal Reserve Board, the Missouri Division of Finance, the Illinois Office of Banks and Real Estate or the Arizona State Banking Department has denied approval of the Merger, and neither the Company nor Seller has, within 30 days after the entry of such order denying approval, filed a petition seeking review of such order as provided by applicable law;

(vi) by either the Company or the Seller, if at the Seller Shareholders’ Meeting, this Agreement and the transactions contemplated hereby shall fail to receive the requisite vote for approval and adoption by the Seller’s Shareholders;

(vii) by the Company, if there shall exist a proposal for a Superior Competing Transaction with respect to the Seller and the Board of Directors of the Seller has withdrawn or modified in a manner adverse to the Company its approval and recommendation of this Agreement or its approval of the Merger or any other transaction contemplated hereby or if the

Board of Directors of the Seller shall have approved or recommended such Superior Competing Transaction;

(viii) by the Company if any person or persons holding in the aggregate 5% or more of the outstanding Seller Common Stock deliver a notice or notices of intent to demand payment in accordance with Section 351.455 of the GBCLM; or

(ix) by the Seller if the condition in (A) below exists on the day preceding the anticipated Effective Time and the Company has not elected to exercise its right as set forth in (B) below:

(A) The Valuation Period Market Value is less than $21.44.

(B) The Company shall have the right, but not the obligation, by providing written notice thereof to the Seller, to issue a number of shares of Company Common Stock (the “Additional Per Share Stock Consideration”) with respect to each share of Seller Common Stock converted in accordance with Section 1.6 hereof such that the sum of (I) the product obtained by multiplying (a) the Additional Per Share Stock Consideration by (b) the Valuation Period Market Value and (II) the dollar value of the Per Share Cash Consideration is an amount equal to $47.93. If the Company issues the Additional Shares, the Per Share Cash Consideration for purposes of the calculations made pursuant to Section 1.6 shall be deemed to be $47.93.

SECTION 8.2 Effect of Termination. In the event of the termination of this Agreement pursuant to Section 8.1, this Agreement shall forthwith become void and all rights and obligations of any party hereto shall cease except: (i) as set forth in Section 9.1 of this Agreement and (ii) nothing herein shall relieve any party from liability for any willful breach of this Agreement or shall restrict either party’s rights in the case thereof.

SECTION 8.3 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective Boards of Directors at any time prior to the Effective Time; provided, however, that, after approval of the Merger by the shareholders of Seller, no amendment may made which would reduce the amount or change the type of consideration into which each share of Seller Common Stock shall be converted pursuant to this Agreement upon consummation of the Merger. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

SECTION 8.4 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent other failure.
