AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER is dated as of July , 1999 (the "Agreement"), by and between Community First Bankshares, Inc., a Delaware corporation ("CFB"), and River Bancorp, Inc., a Minnesota corporation ("River") and made with respect to the following recitals.

WHEREAS, the Boards of Directors of CFB and River have approved, and deem it advisable and in the best interests of their respective companies and their stockholders to consummate the business combination transaction provided for herein in which River will be merged with and into CFB (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(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the "Code").

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE 1

THE MERGER

1.1 Effective Time of the Merger. Subject to the provisions of this Agreement, (i) a certificate of merger in substantially the form as attached hereto as Exhibit 1.1A shall be duly prepared, executed and acknowledged by CFB and River and thereafter delivered for filing to the Secretary of State of the State of Delaware, as provided in the Delaware Corporation Law (the "Delaware Law") on the Closing Date (as defined in Section 1.2); and (ii) articles of merger in substantially the form as attached hereto as Exhibit 1.1B shall be duly prepared, executed and acknowledged by CFB and River and thereafter delivered for filing to the Secretary of State of the State of Minnesota, as provided in the Minnesota Business Corporation Act (the "Minnesota Act") on the Closing Date. The Merger shall become effective at the date and time specified in the certificate of merger and the articles of merger (the "Effective Time").

1.2 Closing. Subject to the terms and conditions hereof, the closing of the Merger (the "Closing") will take place prior to the Effective Time and after the satisfaction or waiver (subject to applicable law) of the last to occur of the conditions set forth in Article 6 hereof. The Closing will take place at the offices of Lindquist & Vennum P.L.L.P., at 4200 IDS Center, 80 South 8th Street, Minneapolis, Minnesota, unless another time, date or place is agreed to in writing by the parties hereto. Each of the parties shall use its reasonable best efforts to cause the Closing to be completed within 30 days after the satisfaction or waiver of the conditions set forth in Article 6 of this Agreement.

1.3 Effects of the Merger.

(a) At the Effective Time: (i) the separate existence of River shall cease and River shall be merged with and into CFB; (ii) the Certificate of Incorporation of CFB, as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation (as hereinafter defined) until duly amended in accordance with applicable law; (iii) the By-laws of CFB, as in effect immediately prior to the Effective Time shall be the By-laws of the Surviving Corporation until amended in accordance with applicable law; (iv) the members of Board of Directors of the Surviving Corporation shall consist of the members of the Board of Directors of CFB holding office immediately prior to the Effective Time.

(b) At the Effective Time: (i) the holders of the outstanding capital stock of CFB shall continue as shareholders of the Surviving Corporation; and (ii) the holders of certificates representing shares of

River Common Stock (as defined in Section 2.1(a) below) shall cease to have any rights as shareholders of River, except such rights, if any, as they may have pursuant to Section 302A.471 of the Minnesota Act, and their sole right shall be the right to receive (A) the number of whole shares of CFB Common Stock (as defined in Section 2.1(a) below) into which their shares of River Common Stock have been converted in the Merger as provided herein (together with any dividend payments with respect thereto, to the extent provided in Section 2.2(c) below), and (B) the cash value of any fraction of a share of CFB Common Stock into which their shares of River Common Stock have been converted as provided herein.

(c) As used in this Agreement, the term "Constituent Corporations" shall mean River and CFB. The term "Surviving Corporation" shall mean CFB, after giving effect to the Merger.

(d) At and after the Effective Time, the Merger will have the effects set forth in Section 252 of the Delaware Law.

1.4 Calculation of River Value.

(a) As of the "Determination Date" (as hereinafter defined), River shall prepare a consolidated balance sheet of River in accordance with generally accepted accounting principles, but excluding the effects of any adjustments otherwise required by FASB 115 and excluding any footnotes that might be required to be included with such financial statements (the "Determination Date Financial Statements"). The Determination Date Financial Statements shall be prepared and delivered to CFB not less than five (5) business days prior to the Effective Time, so that CFB and its accountants may review and confirm their accuracy. For purposes of this Agreement, the "River Value" shall be equal to the total consolidated tangible assets of River minus the total consolidated liabilities of River, as reflected on the Determination Date Financial Statements, prepared in accordance with this Section 1.4. "River Value" shall take into account, without limitation, any and all tax liability or balance sheet adjustments that will be incurred or required to be recognized as a result of the termination of S-elections by River and its subsidiary Bank upon consummation of the Merger. Total consolidated liabilities of River shall include, without limitation, provisions for (i) income and real property taxes, (ii) the expenses of preparation of final tax returns or reports of River and (iii) all anticipated transaction expenses.

(b) As used herein, the "Determination Date" shall be the last day of the month immediately preceding the month in which the Effective Time occurs; provided, however, that in the event the Effective Time shall be within the first ten days of a calendar month, the "Determination Date" shall be the last day of the month next preceding the month in which the Effective Time occurs, and income for the period between the Determination Date and the Effective Time occurs shall be determined by multiplying the number of days in the period by the average daily net income (determined by dividing year-to-date net income through the Determination Date by the number of days from January 1, 1999 to the Determination Date).

ARTICLE 2

EFFECT OF THE MERGER ON THE CAPITAL STOCK

2.1 Effect on Capital Stock.

(a) Conversion. At the Effective Time, by virtue of the Merger and without any action on the part of any holder of shares of common stock, $1.00 par value, of River ("River Common Stock"), each issued and outstanding share of River Common Stock, other than shares of River Common Stock held by persons who have taken all steps required to perfect their right to be paid the fair value of such shares under Section 302A.471 of the Minnesota Act, shall be exchanged for validly issued, fully paid and nonassessable shares of common stock of CFB, $.01 par value ("CFB Common Stock").

The number of shares of CFB Common Stock exchanged for shares of River Common Stock shall be determined in accordance with Section 2.1(b). All such shares of River Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist. Each River shareholder's certificate or certificates previously representing shares of River Common Stock (each a "River Certificate") shall be aggregated (if a single stockholder holds more than one River Certificate) and exchanged for a single certificate representing whole shares of CFB Common Stock and cash in lieu of any fractional share issued in consideration therefor upon the surrender of such River Certificates in accordance with Section 2.2, without any interest thereon. In the event that, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding shares of CFB Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities through a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in CFB's capitalization, then an appropriate and proportionate adjustment shall be made to the "Exchange Rate," as hereinafter defined, so that the number of shares of CFB Common Stock for which a share of River Common Stock shall be exchanged will equal the number of shares of CFB Common Stock that the holders of shares of River Common Stock would have received pursuant to such reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change had the record date therefor been immediately following the Closing Date.

(b) Exchange Rate. Subject to (i) the confirmation of the minimum River Value, as provided in Section 6.2(c) hereof and (ii) the limitations and conditions of Section 2.1(c) hereof, the aggregate number of shares of CFB Common Stock to be exchanged for all of the issued and outstanding shares of River Common Stock and any and all options, warrants and rights exercisable for or convertible into shares of River Common Stock (the "Merger Consideration") shall be 300,000 shares of CFB Common Stock.

For purposes of this Agreement, the "Exchange Rate" shall be determined by dividing the Merger Consideration, as determined above, by the number of shares of River Common Stock outstanding or subject to option, warrant or other right of issuance, whether or not vested or accrued as of the Effective Time.

All calculations will be rounded to four decimal places. Any fractional share of CFB Common Stock will be paid in cash in accordance with Section 2.2(e).

(c) Adjustments to Merger Consideration Based on CFB Trading Value. Notwithstanding anything to the contrary in this Article 2, Merger Consideration shall be subject to modification as set forth below:

(i) If the CFB Trading Value is less than $18 per share, then the number of shares of CFB Common Stock to be issued in exchange for all of the issued and outstanding shares of River Common Stock shall be determined by dividing $5,400,000 by the CFB Trading Value.

(ii) If the CFB Trading Value is greater than $22 per share, then the number of shares of CFB Common Stock to be issued for all of the issued and outstanding shares of River Common Stock shall be determined by dividing $6,600,000 by the CFB Trading Value.

For purposes of this Agreement, the "CFB Trading Value" of the CFB Common Stock shall be the average of the per share closing price for the CFB Common Stock as reported by the Nasdaq Stock Market for the 20 trading days ending at the end of the fourth trading day immediately preceding the Closing Date (as appropriately and proportionately adjusted in the event that, between the date hereof and the termination of such 20 trading day period, shares of CFB Common Stock shall be changed into a different number of shares or a different class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment or stock

dividend). Illustrations of the Exchange Rate calculations are attached as Exhibit 2.1(c) hereto and incorporated herein by reference.

(d) Adjustments to Exchange Rate Based on River Value. River shall use its best efforts to distribute all amounts in excess of the minimum River Value (as provided in Section 6.2(c) hereof) to its shareholders on or before the Determination Date. In the event that the River Value, calculated in accordance with Section 1.4, above, shall be greater than $2,012,605, then, at the election of River and subject to the requirements of Section 6.2(d) hereof, either (i) the difference shall be paid by special dividend to River shareholders immediately prior to the Determination Date or (ii) the Merger Consideration determined in accordance with Sections 2.1(b) and (c) shall be subject to increase. The amount of increase shall be determined by (i) subtracting the difference between the River Value and $2,012,605, and then (ii) dividing such difference by the CFB Trading Value. In the event that the River Value, calculated in accordance with Section 1.4, above, shall be less than $2,012,605, then the Merger Consideration shall be reduced. The amount of reduction shall be determined by subtracting the difference between $2,012,605 and the River Value, and then dividing such difference by the CFBX Trading Value.

(e) Shareholders' Right of Dissent. Any holder of shares of River Common Stock who does not vote in favor of the Merger at the meeting of shareholders of River called to vote on the Merger and has given notice in writing to the presiding officer prior to or at the meeting of his or her objection to the proposed corporate action shall be entitled to demand to receive the fair value of the River Common Stock so held by him or her, in accordance with Section 302A.471 of the Minnesota Act.

2.2 Exchange of Certificates.

(a) Exchange Agent. At the Closing, CFB shall deposit with Norwest Bank Minnesota, N.A. or such other bank or trust company acceptable to the parties (the "Exchange Agent"), for the benefit of the holders of shares of River Common Stock, certificates dated the Closing Date representing the shares of CFB Common Stock and the cash to be paid in lieu of fractional shares (such cash and certificates for shares of CFB Common Stock together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Exchange Fund") to be issued and paid pursuant to Section 2.1 in exchange for the outstanding shares of River Common Stock.

(b) Exchange Procedures. At the Closing CFB shall deliver to each holder of record of a River Certificate or River Certificates (i) a letter of transmittal which shall specify that delivery shall be effective, and risk of loss and title to the River Certificate(s) shall pass, only upon delivery of the River Certificate(s) to the Exchange Agent and which shall be in such form and have such other provisions as CFB and River may reasonably specify not later than five business days before the Closing Date and (ii) instructions for use in effecting the surrender of the River Certificate(s) in exchange for a certificate representing shares of CFB Common Stock and the cash to be paid in lieu of any fractional share. Upon surrender of a shareholder's River Certificate or River Certificates for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, the holder of such River Certificate(s) shall be entitled to receive in exchange therefor (1) a certificate representing the number of whole shares of CFB Common Stock and (2) a check representing the amount of the cash to be paid in lieu of a fractional share, if any, and unpaid dividends and distributions, if any, which such holder has the right to receive in respect of the River Certificate(s) surrendered, as provided in Section 2.2(c) below, and the River Certificate(s) so surrendered shall forthwith be canceled. No interest will be paid on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of River Certificates. In the event of a transfer of ownership of River Common Stock which is not registered in the transfer records of River, a CFB Certificate representing the proper number of shares of CFB Common Stock, together with a check for the cash to be paid in lieu of a fractional share, may be issued to such a transferee if the River Certificate representing such River Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer.

(c) Distributions and Voting. The Exchange Agent shall receive and hold, for distribution without interest to the first record holder of the certificate or certificates representing shares of River Common Stock, all dividends and other distributions paid on shares of CFB Common Stock held in the Exchange Agent's name as agent. Holders of unsurrendered River Certificates shall not be entitled to vote after the Closing Date at any meeting of CFB shareholders until they have exchanged their River Certificates.

(d) Transfers. After the Effective Time, there shall be no transfers on the stock transfer books of River of the shares of River Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, River Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for the shares of CFB Common Stock and cash, in an amount as determined in accordance with the provisions of Section 2.1(a) and this Section 2.2, deliverable in respect thereof pursuant to this Agreement. River Certificates surrendered for exchange by any person constituting an "affiliate" of River for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities Act"), shall not be exchanged until CFB has received a written agreement from such person as provided in Section 5.2.

(e) Fractional Shares. No fractional shares of CFB Common Stock shall be issued pursuant hereto. In lieu of the issuance of any fractional share, cash adjustments will be paid to holders in respect of any fractional share of CFB Common Stock that would otherwise be issuable, and the amount of such cash adjustment shall be equal to such fractional proportion of the Trading Value of a share of CFB Common Stock. For purposes of calculating fractional shares, a holder of River Common Stock with more than one River Certificate shall receive cash only for the fractional share remaining after aggregating all of its, his or her River Common Stock to be exchanged.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof and any CFB Common Stock) that remains unclaimed by the shareholders of River for 12 months after the Closing Date shall be paid to CFB. Any shareholders of River who have not theretofore complied with this Article 2 shall thereafter look only to CFB for payment of their shares of CFB Common Stock, and cash in an amount as determined in accordance with the provisions of Section 2.1(a) and this Section 2.2, without any interest thereon. Notwithstanding the foregoing, none of CFB, the Exchange Agent nor any other person shall be liable to any former holder of shares of River Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) Withholding Rights. CFB shall be entitled to deduct and withhold from any cash consideration payable pursuant to this Agreement to any holder of River common stock such amounts as CFB is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by CFB, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the River Common Stock in respect of which such deduction and withholding was made by River Common Stock.

(h) Lost or Destroyed Certificates. In the event any River Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such River Certificate to be lost, stolen or destroyed and, if required by the Exchange Agent, the posting by such person of a bond in such amount as CFB may direct as indemnity against any claim that may be made against it with respect to such River Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed River Certificate the shares of CFB Common Stock, and cash in an amount as determined in accordance with the provisions of Section 2.1(a) and this Section 2.2, deliverable in respect thereof pursuant to this Agreement.

2.3 River Stock Options. On or before the Effective Time, River shall provide for the acceleration and exercise of all such options, warrants and rights or their termination and written release of River from further liability thereunder. At the Effective Time, each option granted by River to purchase shares of River Common Stock which is outstanding and unexercised immediately prior thereto shall cease to represent any right to acquire shares of River Common Stock or CFB Common Stock.

2.4 Stock Transfer Books. At the Effective Time, the stock transfer books of River shall be closed and there shall be no further registration of transfers of shares of River Common Stock thereafter on the records of River. From and after the Effective Time, the holders of certificates evidencing ownership of shares of River Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares except as otherwise provided herein or by law. On or after the Effective Time, any certificates presented to the Exchange Agent or CFB for any reason shall be converted into shares of CFB Common Stock in accordance with this Agreement.

ARTICLE 3

REPRESENTATIONS AND WARRANTIES

3.1 Representations and Warranties of River. In order to induce CFB to enter into this Agreement, River represents and warrants to CFB, in all material respects, as of the date of this Agreement (except as otherwise expressly provided), as follows, except as disclosed on the attached Exhibit 3.1 (the "River Disclosure Schedule"):

(a) Subsidiary Organizations. River's sole subsidiary is Northland Security Bank (the "Bank"). The Bank is a banking corporation duly organized and validly existing and in good standing under the laws of the State of Minnesota. River owns all of the shares of stock of the Bank, free and clear of any liens or encumbrances. The authorized capital of the Bank consists of 1,000 shares of voting common stock, par value $100 per share, of which 1,000 shares of stock are presently issued and outstanding, all of which have been validly issued, fully paid and non-assessable, and there are no stock options or other commitments outstanding pursuant to which the Bank is obligated to issue additional shares of such stock or purchase or redeem any outstanding shares of such stock.

(b) River Organization. River is a corporation duly organized, validly existing and in good standing under the laws of the State of Minnesota, with authorized capital stock consisting of 100,000 shares of common stock (the "River Common Stock"), $1.00 par value per share, of which 10,000 shares are issued and outstanding and none are subject to options. All of the shares of River Common Stock issued and outstanding have been validly issued, fully paid and non-assessable. There are no options, warrants or other commitments outstanding pursuant to which River is or could become obligated to issue additional shares (the "River Options"). River has all requisite power, authority, charters, licenses and franchises necessary or required by law to carry on the business activity in which it is presently engaged, except where the failure to have any such power, authority, charter, license or franchise would not reasonably be expected to have a material adverse effect on the business, operations, prospects or financial condition of River. River is registered as a company under Section 1841 of Title 12, United States Code, as amended (the "Bank Holding Company Act" or "BHCA"). River has no direct or indirect subsidiaries except the Bank and is not a partner to any partnership.

(c) Enforceability. Subject only to the required approval of the Merger by the shareholders of River, River has the corporate power and authority to enter into this Agreement and to carry out its obligations hereunder. The execution, delivery and performance of this Agreement by River and the consummation of the transactions contemplated hereby have been duly authorized by the Board of Directors of River. Subject to approval by the River shareholders and of government agencies and other governing bodies having regulatory authority over River or the Bank, as may be required by

statute or regulation, this Agreement constitutes a valid and binding obligation of River, enforceable against it in accordance with its terms.

(d) Reports. River and the Bank have filed all reports, registrations, applications and statements, together with any required amendments thereto, that they were required to file with (i) the Securities and Exchange Commission ("SEC"), (ii) the Board of Governors of the Federal Reserve (the "Federal Reserve Board"), (iii) the Federal Deposit Insurance Corporation (the "FDIC"), and (iv) any applicable state securities or banking authorities. All such reports and statements filed with any such regulatory body or authority are collectively referred to herein as the "River Reports." As of their respective dates, the River Reports complied in all material respects with all the rules and regulations promulgated by the SEC, the Federal Reserve Board, the FDIC and any applicable state securities or banking authorities, as the case may be, and did not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(e) Limitation of Bank's Powers. There are no proceedings or actions pending by any federal or state regulatory body having authority over the Bank to limit or impair any of its powers, rights or privileges, to terminate deposit insurance or to dissolve the Bank. The Bank has not received any written protest, complaint or criticism in the last three years by the public or any regulatory agency relating to the Bank's performance under the Community Reinvestment Act or any other consumer protection statute or regulation.

(f) Corporate Records. River's Articles of Incorporation and Bylaws, and the Bank's Certificate of Incorporation and Bylaws are each unchanged from the form in which they were delivered to CFB on or before the date of this Agreement. The minute books of River and the Bank contain reasonably complete and accurate records of all meetings and corporate actions of each of their respective shareholders and Boards of Directors (including committees of the Boards of Directors).

(g) Insured Status of Bank. The Bank is an insured bank under the provisions of Chapter 16 of Title 12, United States Code, known as the "Federal Deposit Insurance Act," and no act or default on the part of the Bank exists that could reasonably be expected to have a material adverse effect on its status as an insured bank thereunder. The Bank possesses and is in full compliance with all licenses, franchises, permits and other governmental authorizations that are legally required to hold its properties or conduct its business, except where the failure to possess any such licenses, franchises, permits or other governmental authorizations would not reasonably be expected to have a material adverse effect on River or the Bank.

(h) No Default or Creation of Liens. Neither the execution and delivery of this Agreement, nor the consummation of the Merger will conflict with, result in the breach of, constitute a default under or accelerate the performance provided by the terms of any judgment, order or decree of any court or other governmental agency to which River or the Bank may be subject, any of the "Material Contracts," as hereinafter defined, or the Certificate of Incorporation, Articles of Incorporation and Bylaws of River or the Bank, or constitute an event that, with the lapse of time or action by a third party, would result in a default under any of the foregoing or result in the creation of any lien, charge or encumbrance upon the River Common Stock or the Bank's capital stock.

(i) Financial Statements. The following financial statements of the Bank and River (each, a "Financial Statement") have been delivered to CFB and are incorporated by reference herein:

(i) The Consolidated Reports of Condition and Income of the Bank as of December 31 for each of the years 1996, 1997 and 1998 and the period ending March 31, 1999; and

(ii) The consolidated financial statements of River, prepared in the ordinary course of business for each of the years ended December 31, 1996, 1997 and 1998.

Each of the aforementioned financial statements is true and correct in all material respects, and together they fairly present, (on a consistent basis except as disclosed in the footnotes thereto and except that the unaudited financial statements are subject to any adjustments which might be required as a result of an examination by independent accountants) the financial position and results of operation of River and the Bank as of the dates and for the periods therein set forth. To the knowledge of River, such financial statements did not, as of the date of the preparation thereof, include any material assets or omit to state any material liability, absolute or contingent, the inclusion or omission of which renders such financial statements, in light of the circumstances in which they were made, misleading in any material respect.

(j) Material Adverse Change. Since December 31, 1998, there has been no material adverse change in the financial condition, results of operation or business of River or the Bank, taken as a whole (other than changes in banking laws or regulations, changes in generally accepted accounting principles or interpretations thereof that affect the banking industry generally, or changes in general economic conditions that affect the banking industry on a nationwide basis, including changes in the general level of interest rates).

(k) Fidelity Insurance. The Bank is insured under a Banker's Blanket Bond which is in full force and effect and the Bank has not received notice of cancellation or non-renewal thereof, or filed any claim thereunder during the past five years. There are no unresolved claims.

(l) Employment Contracts. Neither River nor the Bank is a party to or bound by any written or oral (i) employment or consulting contract that is not terminable without penalty by River or the Bank on 30 days' or less notice or (ii) any collective bargaining agreement covering employees. River and the Bank are in material compliance with all applicable laws respecting employment and employment practices, terms and conditions of employment and wages and hours, and are not engaged in any unfair labor practice. There is no unfair labor practice complaint against River or the Bank pending before the National Labor Relations Board. There is no labor strike, dispute, slowdown, representation campaign or work stoppage actually pending or threatened against or affecting River or the Bank. No grievance or arbitration proceeding arising out of or under collective bargaining agreements is pending and no claim therefor has been asserted against River or the Bank. Neither River nor the Bank is experiencing any material work stoppage.

(m) Employee Benefits. The River Disclosure Schedule lists every employee benefit plan within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), which River or the Bank maintains or to which River or the Bank contributes on behalf of current or former employees of River or the Bank. All of the plans and programs listed in Section 3.1(m) of the River Disclosure Schedule (hereinafter referred to as the "Plans") are in compliance in all material respects with all applicable requirements of ERISA and all other applicable federal and state laws. Each of the Plans that is a defined benefit pension plan has assets with an aggregate value that exceeds the present value of its liability for accrued benefits, all as determined on a termination basis, using appropriate interest and discount rates. None of the Plans has engaged in a "prohibited transaction," within the meaning of Section 4975 of the Code or Section 406 of ERISA, none of the Plans which is subject to Title IV of ERISA or any trust created thereunder has been terminated nor have there been any "reportable events" as that term is defined in Section 4043 of ERISA with respect to any Plan and none of the Plans has incurred an accumulated funding deficiency within the meaning of Section 412(a) of the Code.

River has delivered to CFB copies of (i) each Plan or if no plan document exists, a written summary of the material terms thereof, (ii) current summary plan descriptions of each Plan for which they are required, (iii) each trust agreement, insurance policy or other instrument relating to the funding of any Plan, (iv) the most recent Annual Reports (Form 5500 series) and accompanying schedules filed with the IRS or United States Department of Labor with respect to each Plan for

which they are required, (v) the most recent determination letter issued by the IRS with respect to each Plan that is intended to qualify under Section 401 of the Code, and (vi) the most recent available financial statements for each Plan that has assets.

(n) Litigation. No claims have been asserted by written notice to River or the Bank and no relief has been sought against River, the Bank, or any of the Plans in any pending litigation or governmental proceedings or otherwise. Neither River nor the Bank is a party to any unsatisfied order, judgment or decree which is adverse to River or the Bank, and neither River nor the Bank nor any Plan (i) is the subject of any cease and desist order, or other formal or informal enforcement action by any regulatory authority; or (ii) has made any commitment to or entered into any agreement with any regulatory authority that restricts or adversely affects its operations or financial condition. To the knowledge of River, there do not exist facts that would reasonably be expected to give rise to a material claim against River, the Bank, or any Plan after the Closing Date.

(o) Taxes. River and the Bank have filed all federal and state income tax returns and all other returns with respect to any taxes, either federal, state or local, which it is required to have filed; said returns have been correctly and accurately prepared; all taxes reflected thereon have been paid or adequately accrued or reserved for; no notice of any deficiency, assessments or additions to tax have been received by River or the Bank; neither River nor the Bank has waived any statute of limitations with respect to any taxes reflected on said returns; and deferred taxes have been properly reflected on the Financial Statements. There are no other taxes of any kind or character for which River or the Bank is or may be liable which are now past due, delinquent and/or unpaid. Neither River nor the Bank has made any payments, or been a party to an agreement that under any circumstances could obligate it to make payments based upon the consummation of the transactions contemplated hereby constituting a change of the nature described in Section 280G of the Code, that are or will not be deductible because of Section 280G of the Code.

(p) Title to Property. Each of River and the Bank have good and marketable title to all material assets and properties, whether real or personal, that it purports to own, including without limitation all real and personal assets and properties reflected on the most recent Financial Statement, or acquired subsequent thereto (except to the extent that such assets and properties have been disposed of for fair value in the ordinary course of business since such date) subject to no liens, mortgages, security interests, encumbrances or charges of any kind, except (i) as noted in said Financial Statement; (ii) statutory liens for taxes not yet delinquent; (iii) security interests granted to secure deposits of funds by federal, state or other governmental agencies; (iv) minor defects and irregularities in title and encumbrances that do not materially impair the use thereof for the purposes for which they are held as of the date hereof; and (v) such liens, mortgages, security interests, encumbrances and charges that are not in the aggregate material to the assets and properties of River or the Bank, as the case may be.

(q) Insurance Policies. Each of the insurance policies listed on Disclosure Schedule, which constitute all insurance policies of River and the Bank as of the date of this Agreement, is in full force and effect, with all premiums due thereon on or prior to the date of this Agreement having been paid as and when due.

(r) Bank Property. All buildings, structures, fixtures, and appurtenances comprising the premises of River and the Bank (the "Property") are in good condition, subject to ordinary wear and tear. Except for the facts set forth in the Assessment (as hereinafter defined), to the best knowledge of River, River and the Bank are, and have been at all times, in substantial compliance with all applicable Environmental Laws (as defined below), and have not engaged in any activity resulting in a material violation of any applicable Environmental Law. There are no underground or above ground storage tanks (whether or not currently in use) located on or under the Property, and no underground tank previously located on the Property has been removed therefrom. To the best knowledge of River,

there is no legal, administrative, or other proceeding, claim, investigation inquiry, order, hearing or action of any nature seeking to impose, or that would reasonably be expected to result in the imposition, on River or the Bank of any liability arising from any violation of or obligation under any local, state or federal environmental statute, regulation or ordinance including, without limitation, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("Environmental Laws"), pending or threatened against River or the Bank; to the knowledge of River and except for the facts set forth in the Assessment, there is no reasonable basis for any such proceeding, claim, investigation, inquiry, order, hearing or action; and neither River nor the Bank is subject to any agreement, order, judgment, or decree by or with any court, governmental authority or third party imposing any such environmental liability. No claims have been made by any governmental authority or third party against River or the Bank relating to damage, contribution, cost recovery, compensation, loss or inquiry resulting from any violation of or obligation under any Environmental Law.

(s) Conduct of Business. Except for the facts set forth in the Assessment, River and the Bank are in compliance in all material respects with all laws, regulations and orders (including zoning ordinances) applicable to them and to the conduct of their business, including without limitation, all statutes, rules and regulations pertaining to the conduct of the Bank's banking activities (including the exercise of fiduciary and trust powers), except where the failure to comply would not reasonably be expected to have a material adverse effect on River or the Bank.

(t) Internal Controls and Records. River and the Bank maintain books of account which accurately and validly reflect, in all material respects, all loans, mortgages, collateral and other business transactions and maintain accounting controls sufficient to ensure that all such transactions are in all material respects, executed in accordance with its management's general or specific authorization. There is no amendment to any lending agreement, collateral document or security which is not fully reflected in the books and records of River and the Bank.

(u) Loan Allowance and Documentation. The Bank's consolidated allowance for losses on loans included in the Financial Statements as of March 31, 1999 was $227,292, representing 0.86% of its total consolidated loans held in portfolio. The amount of such allowance for losses on loans was adequate to absorb reasonably expectable losses in the loan portfolio of the Bank. After due inquiry as to potential losses, and based upon past loan experience, the executive officers of the Bank know of no facts which would indicate that the portion of the loan portfolio of the Bank as of March 31, 1999 in excess of such reserves is not fully collectible in accordance with the terms of the documentation relating to the loans in such portfolio. The documentation relating to loans made by the Bank and relating to all security interests, mortgages and other liens with respect to all collateral for such loans, taken as a whole, is adequate for the enforcement of the material terms of such loans and of the related security interests, mortgages and other liens. The terms of such loans and of the related security interests, mortgages and other liens comply in all material respects with all applicable laws, rules and regulations (including laws, rules and regulations relating to the extension of credit). There are no loans, leases, other extensions of credit or commitments to extend credit of the Bank that have been or should in accordance with generally accepted accounting principles, have been classified by the Bank as nonaccrual, as restructured, as 90 days past due, as still accruing and doubtful of collection or any comparable classification. To the best knowledge of River, River has provided to CFB true, correct and complete in all material respects such written information concerning the loan portfolio of the Bank as CFB has requested.

(v) Leases and Contracts. Neither River nor the Bank is a party to or bound by any written or oral (i) lease or license with respect to any property, real or personal, with a value in excess of $25,000, whether as a lessor, lessee, licensor or licensee; (ii) contract or commitment for capital expenditures in excess of $25,000 for any one project or $50,000 in the aggregate; (iii) contract or commitment for total expenses in excess of $25,000 made in the ordinary course of business for the purchase of

materials, supplies, or for the performance of services for a period of more than 180 days from the date of this Agreement; (iv) contract or option for the purchase or sale of any real or personal property other than in the ordinary course of business; or (v) any other contract, agreement or understanding which is not terminable by River or the Bank without additional payment or penalty within 60 days and obligates River or the Bank for payments or other consideration with a value in excess of $25,000 (all such agreements, contracts, and commitments collectively are herein referred to as the "Material Contracts"). Each of the Bank and River have performed in all material respects all obligations required to be performed by them to date, and are not in material default under, and no event has occurred which, with the lapse of time or action by a third party, could result in a material default under any of the Material Contracts to which the Bank or River is a party or by which the Bank or River is bound. Each of the Material Contracts is a valid and legally binding obligation of River or the Bank and the other party or parties thereto, subject to (i) all applicable bankruptcy, insolvency, moratorium or other similar laws affecting the enforcement of creditors' rights generally, and (ii) the application of equitable principles if equitable remedies are sought.

(w) Shareholder Lists. River has furnished to CFB a shareholder list as of the date set forth therein and other documentation that together therewith (i) sets forth the record name and number of shares held by each holder of common stock of River and (ii) identifies each shareholder who is an officer or director of the Bank or River.

(x) Bank Principals. No director or executive officer of River or the Bank, nor any holder of ten percent or more of the outstanding capital stock of River, nor any affiliate of such person as that term is defined under 12 USC 371(c) ("Bank Principal") (i) is or has during the period subsequent to December 31, 1996, been a party (other than as a depositor) to any transaction with any of the Bank, whether as a borrower or otherwise, which (a) was made other than in the ordinary course of business; (b) was made on other than substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions for other persons; or (c) involves more than the normal risk of collectibility or presents other unfavorable features; or (ii) is a party to any loan or loan commitment, whether written or oral, from the Bank involving an amount in excess of $10,000. No Bank Principal holds any position with any depository organization other than with the Bank or with River. For the purposes of this provision, the term "depository organization" means a commercial bank (including a private bank), a savings bank, a trust company, a savings and loan association, a homestead association, a cooperative bank, an industrial bank, a credit union, or a depository organization holding company.

(y) Information Supplied. None of the information supplied or to be supplied by River or the Bank to the River stockholders for the meeting of stockholders of River to be held in connection with the Merger, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

(z) Agreements with Bank Regulators. Neither River nor the Bank: (i) is a party to any written agreement or memorandum of understanding with; (ii) is subject to any order or directive by; (iii) is subject to any extraordinary supervisory letter from; or (iv) has adopted any Board resolutions at the request of, federal or state governmental entities charged with the supervision or regulation of banks or bank holding companies or engaged in the insurance of bank deposits ("Bank Regulators"), nor has River been advised that any Bank Regulator is contemplating issuing or requesting any such order, directive, written agreement, memorandum of understanding, extraordinary supervisory letter, commitment letter, board resolutions or similar undertaking.

(aa) Year 2000. All "mission critical" systems of the Bank and River are "year 2000 compliant," in accordance with applicable FFIEC Interagency Statements and related releases.

3.2 Representations and Warranties of CFB. In order to induce River to enter into this Agreement, CFB represents and warrants to River, in all material respects, as of the date of this Agreement (except as otherwise expressly provided) as follows, except as disclosed on the attached Exhibit 3.2 (the "CFB Disclosure Schedule"):

CFB is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, with authorized capital stock consisting of 80,000,000 shares of common stock, par value of $.01 per share, of which 47,128,274 shares were issued and outstanding as of March 31, 1999 and 2,000,000 shares of preferred stock, no shares of which were issued and outstanding as of December 31, 1998. CFB has all requisite power, authority, charters, licenses and franchises necessary or required by law to carry on the business activity in which it is presently engaged, except where the failure to have any such power, authority, charter, license or franchise would not reasonably be expected to have a material adverse effect on CFB. CFB is registered as a company under the Bank Holding Company Act. The shares of CFB Common Stock to be issued pursuant to this Agreement have been duly authorized and will be validly issued pursuant to a registration statement filed and declared effective by the SEC, fully paid and non-assessable, and subject to no restrictions upon transferability other than Rule 144 and 145(d) of the SEC and requirements for qualification for pooling accounting treatment.

(b) Reports. CFB and its subsidiaries have filed all reports, registrations, applications and statements, together with any required amendments thereto, that they were required to file with (i) the SEC, including, but not limited to, Forms 10-K, Forms 10-Q and proxy statements, (ii) the Federal Reserve Board, (iii) the FDIC, (iv) the Comptroller and (v) any applicable state securities or banking authorities. All such reports and statements filed with any such regulatory body or authority are collectively referred to herein as the "CFB Reports." As of their respective dates, the CFB Reports complied in all material respects with all the rules and regulations promulgated by the SEC, the Federal Reserve Board, the FDIC, the Comptroller and any applicable state securities or banking authorities, as the case may be, and did not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. CFB has timely filed with the SEC all reports, statements and forms required to be filed pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act").

(c) Enforceability. The execution, delivery and performance of this Agreement by CFB and the consummation of the transactions contemplated hereby and thereby have been duly authorized by the Board of Directors of CFB. Subject to approval by the government agencies and other governing bodies having regulatory authority over CFB as may be required by statute or regulation, this Agreement constitute valid and binding obligations of CFB, enforceable against it in accordance with their respective terms. This Agreement does not require the approval of CFB shareholders.

If the Merger contemplated by this Agreement shall not be consummated, such confidence shall be maintained and such information shall not be used in competition with CFB (except to the extent that such information can be shown to be previously known to River, in the public domain, or later acquired by River from other legitimate sources) and, upon request, all such documents, any copies thereof and extracts therefrom shall immediately thereafter be returned to CFB.

(e) Benefit Plans. River and the Bank shall terminate each of the agreements and arrangements with directors and/or officers identified on Exhibit 4.1(e), attached hereto, on a basis mutually agreeable to the parties to the respective agreement or arrangement, and shall fully expense or accrue as of the Determination Date Financial Statements, any resulting financial obligation or liability incurred.

or eliminate a requirement of mandatory periodic contributions (provided that if any of the Plans do not have assets with an aggregate value that exceeds the present value of its liability for accrued benefits, all as determined on a termination basis, then River shall accrue on its Determination Date Financial Statements the amount by which any of the Plans are underfunded); (ii) except as provided in Section 4.1(i)(xix), below, increase in any manner the compensation of any director, officer, or employee, or pay any benefit not required by any plan and arrangement as in effect as of the date hereof (including, without limitation, the granting of stock options, stock appreciation rights, restricted stock, restricted stock units or performance units or shares) or enter into any contract, agreement, commitment or arrangement to do any of the foregoing.

In the event of any such objection, then River shall have 30 days from the date of such objection within which to attempt to eliminate such objections to exceptions to title from the Title Commitment.
