Agreement and Plan of Merger

THIS AGREEMENT AND PLAN OF MERGER (the "Agreement") is made as of the 9th day of February, 2006, by and between the Tax-Free National Fund series of Mosaic Tax-Free Trust, a Massachusetts business trust (the "Trust"), with its principal place of business at 550 Science Drive, Madison, Wisconsin 53711 (the "Acquiring Fund"), and the Tax-Free Missouri Fund series of the Trust (the "Selling Fund").

This Agreement is intended to be and is adopted as a plan of reorganization and liquidation within the meaning of Section 368 (a)(1)(C) of the United States Internal Revenue Code of 1986 (the "Code"). The reorganization (the "Merger") will consist of the transfer of substantially all of the assets of the Selling Fund in exchange solely for shares of beneficial interest, no par value per share, of the Acquiring Fund (the "Acquiring Fund Shares") and the assumption by the Acquiring Fund of certain stated liabilities of the Selling Fund and the distribution, after the Merger Date hereinafter referred to, of the Acquiring Fund Shares to the shareholders of the Selling Fund in liquidation of the Selling Fund as provided herein, all upon the terms and conditions hereinafter set forth in this Agreement.

WHEREAS, both Funds are separate investment series of an open-end, registered investment company of the management type, and the Selling Fund owns securities that generally are assets of the character in which the Acquiring Fund is permitted to invest;

WHEREAS, both Funds are authorized to issue their shares of beneficial interest;

WHEREAS, the Trustees of the Trust have determined that the exchange of substantially all of the assets of the Selling Fund for Acquiring Fund Shares and the assumption of certain stated liabilities by the Acquiring Fund on the terms and conditions hereinafter set forth is in the best interests of the Acquiring Fund shareholders and that the interests of the existing shareholders of the Acquiring Fund will not be diluted as a result of the transactions contemplated herein;

WHEREAS, the Trustees of the Trust have also determined that the Selling Fund should transfer substantially all of its assets to the Acquiring Fund in exchange for the Acquiring Fund Shares and the assumption of certain liabilities by the Acquiring Fund, on the terms and conditions hereinafter set forth, that such transfer is in the best interests of the Selling Fund's shareholders, and that the interests of the existing shareholders of the Selling Fund will not be diluted as a result of the transactions contemplated herein:

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

ARTICLE I

Transfer of Assets of the Selling Fund in Exchange for the Acquiring Fund Shares and Assumption of Selling Fund Liabilities and Liquidation of the Selling Fund

1.1 The Exchange. Subject to the terms and conditions herein set forth and on the basis of the representations and warranties contained herein, the Selling Fund agrees to transfer the Selling Fund's assets as set forth in paragraph 1.2 to the Acquiring Fund, and the Acquiring Fund agrees in exchange therefore

(i) to deliver to the Selling Fund the number of Acquiring Fund Shares, including fractional Acquiring Fund Shares, determined by dividing the value of the Selling Fund's net assets computed in the manner and as of the time and date set forth in paragraph 2.1 by the net asset value of one Acquiring Fund Share computed in the manner and as of the time and date set forth in paragraph 2.2; and

(ii) to assume certain liabilities of the Selling Fund, as set forth in paragraph 1.3. Such transactions shall take place at the closing provided for in paragraph 3.1 (the "Merger Date").

1.2 Assets to be Acquired. The assets of the Selling Fund to be acquired by the Acquiring Fund shall consist of all property, including without limitation all cash, securities, commodities and futures interests and dividends or interest receivable, which is owned by the Selling Fund and any deferred or prepaid expenses shown as an asset on the books of the Selling Fund on the Merger Date. There have been no changes in either Fund's financial position as reflected in the Trust's September 30, 2005 audited financial statements other than those occurring in the ordinary course of their business in connection with the purchase and sale of securities and the payment of normal operating expenses. The Selling Fund reserves the right to sell any of such securities but will not, without the prior written approval of the Acquiring Fund, acquire any additional securities other than securities of the type in which the Acquiring Fund is permitted to invest. In the event that the Selling Fund holds any investments which the Acquiring Fund may not hold, the Selling Fund will dispose of such securities prior to the Merger Date. In addition, if it is determined that the Selling Fund and the Acquiring Fund portfolios, when aggregated, would contain investments exceeding certain percentage limitations imposed upon the Acquiring Fund with respect to such investments, the Selling Fund will dispose of a sufficient amount of such investments as may be necessary to avoid violating such limitations as of the Merger Date.

1.3 Liabilities to be Assumed. The Selling Fund will endeavor to discharge all of its known liabilities and obligations prior to the Merger Date. The Acquiring Fund shall assume only those liabilities, expenses, costs, charges and reserves reflected on a Statement of Assets and Liabilities of the Selling Fund prepared by Madison Mosaic, LLC, the investment advisor and administrator of the Trust, as of the Valuation Date (as defined in paragraph 2.1), in accordance with generally accepted accounting principles consistently applied from the prior audited period.

1.4 Liquidation and Distribution. As soon after the Merger Date as is conveniently practicable (the "Liquidation Date"), (a) the Selling Fund will liquidate and distribute pro rata to the Selling Fund's shareholders of record, determined as of the close of business on the Merger Date (the "Selling Fund Shareholders"), the Acquiring Fund Shares received by the Selling Fund pursuant to paragraph 1.1. and (b) the Selling Fund will thereupon proceed to dissolve as set forth in paragraph 1.8 below. Such liquidation and distribution will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of the Selling Fund on the books of the Acquiring Fund, to open accounts on the share records of the Acquiring Fund in the names of the Selling Fund Shareholders and representing the respective pro rata number of the Acquiring Fund Shares due such shareholders. All issued and outstanding shares of the Selling Fund will simultaneously be canceled on the books of the Selling Fund. The Trust does not issue certificates representing its shares.

1.5 Ownership of Shares. Ownership of Acquiring Fund Shares will be shown on the books of the Trust. Whole or fractional shares of the Acquiring Fund will be issued in the manner described in the Prospectus on Form N-14 to be distributed to shareholders of the Selling Fund as described in Section 5.

1.6 Transfer Taxes. Any transfer taxes payable upon issuance of the Acquiring Fund Shares in a name other than the registered holder of the Selling Fund shares on the books of the Trust as of that time shall, as a condition of such issuance and transfer, be paid by the person to whom such Acquiring Fund Shares are to be issued and transferred.

1.7 Reporting Responsibility. Any reporting responsibility of the Selling Fund is and shall remain the responsibility of the Selling Fund up to and including the Merger Date and such later date on which the Selling Fund is terminated.

1.8 Termination. The business of the Selling Fund shall be wound up and the Selling Fund series of the Trust shall be terminated following the Merger Date and the making of all distributions pursuant to paragraph 1.4.

ARTICLE II

Valuation

2.1 Valuation of Assets. The value of the Selling Fund's assets to be acquired by the Acquiring Fund hereunder shall be the value of such assets computed as of the close of business on the New York Stock Exchange on the business day immediately preceding the Merger Date (such time and date being hereinafter called the "Valuation Date"), using the valuation procedures set forth in the Trust's Declaration of Trust and its current prospectus and statement of additional information.

2.2 Valuation of Shares. The net asset value of an Acquiring Fund Share shall be the net asset value per share computed as of the close of business on the New York Stock Exchange on the Valuation Date, using the valuation procedures set forth in the Trust's Declaration of Trust and current prospectus and statement of additional information, as applicable.

2.3 Shares to be Issued. The number of the Acquiring Fund Shares to be issued (including fractional shares, if any) in exchange for the Selling Fund's assets shall be determined by dividing the value of the assets of the Selling Fund determined using the same valuation procedures referred to in paragraph 2.1 by the net asset value of an Acquiring Fund Share determined in accordance with paragraph 2.2.

2.4 Determination of Value. All computations of value shall be made by Madison Mosaic, LLC in accordance with its regular practice and procedures in pricing the shares and assets of the Trust.

ARTICLE III

Closing and Merger Date

3.1 Merger Date. The Merger Date shall be April 30, 2006 or such later date as the parties may agree to in writing.

3.3 Effect of Suspension in Trading. In the event that on the Valuation Date (a) any primary trading market for portfolio securities of the Acquiring Fund or the Selling Fund shall be closed to trading or trading thereon shall be restricted, or (b) trading or the reporting of trading on the New York Stock Exchange or elsewhere shall be disrupted so that accurate appraisal of the value of the net assets of the Acquiring Fund or the Selling Fund is impracticable, the Merger Date shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.

3.4 Transfer Agent's Certificate. US Bancorp Fund Services, LLC, as transfer agent for each Fund, shall shall issue a confirmation evidencing the Acquiring Fund Shares to be credited on the Merger Date to the Secretary of the Company.
