Votes will be cast at a shareholder meeting scheduled for March 7, 2007. While you are, of course, welcome to join us at the Municipal Bond Fund's meeting, most shareholders cast their vote by filling out and signing the enclosed proxy card or by voting by telephone or over the Internet. You may be aware that MFS offers a wide array of funds designed to meet the investment needs of investors. MFS offers a fund that is similar to the Municipal Bond Fund called MFS(R) Municipal Income Fund (the "Municipal Income Fund"). Municipal Income Fund has a substantially similar investment objective to that of the Municipal Bond Fund and also has investment strategies and policies that are similar to those of the Municipal Bond Fund, although the Municipal Income Fund has the ability to invest in securities that are rated below investment grade to a greater degree than Municipal Bond Fund. This reorganization would provide you with the opportunity to participate in a somewhat larger combined fund with a similar investment objective and similar strategies and policies, potentially lower expenses resulting from fixed costs being spread over a larger asset base, and potentially greater prospects for asset growth over time. After careful consideration, the Municipal Bond Fund's Trustees have unanimously determined that a tax-free reorganization of the Municipal Bond Fund into the Municipal Income Fund would be in your best interests. For this reason, your Trustees recommend that you vote FOR the proposed transaction, by attending the meeting and voting in person, by signing and returning the enclosed proxy card, or by following the instructions on the proxy card to vote via telephone or over the Internet. This proposed reorganization is detailed in the enclosed Prospectus/Proxy Statement. For your convenience, a summary of the transaction is included in question and answer format at the beginning of the Prospectus/Proxy Statement. You should read both thoroughly before voting. YOUR VOTE MAKES A DIFFERENCE No matter what the size of your investment may be, your vote is critical. I urge you to review the enclosed materials and to vote according to the manner specified, either by mail, by phone, via the Internet or in person. Your prompt response will help avoid the need for additional mailings at the Municipal Bond Fund's expense. For your convenience, we have provided a postage-paid envelope should you choose to vote by mail. If you have any questions or need additional information, please contact your financial adviser or call [NUMBER], Monday through Friday between 9:00 A.M. and 11:00 P.M. and Saturday between 12:00 P.M. and 6:00 P.M. Eastern time. I thank you for your prompt vote on this matter. Sincerely, Maria F.

SYNOPSIS The responses to the questions that follow provide an overview of matters that may be particularly relevant to shareholders considering a proposed reorganization between funds. These responses are qualified in their entirety by the remainder of the Prospectus/Proxy Statement, which contains additional information and further details regarding the proposed reorganization. 1. WHAT IS BEING PROPOSED? The Trustees of the Municipal Bond Fund, who are also the Trustees of the Municipal Income Fund, are recommending that shareholders of the Municipal Bond Fund approve the reorganization of the Municipal Bond Fund into the Municipal Income Fund. If approved by shareholders, the assets and liabilities of the Municipal Bond Fund will be transferred to the Municipal Income Fund. In consideration therefore, the Municipal Income Fund will deliver to the Municipal Bond Fund a number of shares of the Municipal Income Fund having an aggregate net asset value equal to the value of the assets of the Municipal Bond Fund less the value of liabilities of the Municipal Bond Fund. Immediately following the transfer, the Municipal Income Fund shares received by the Municipal Bond Fund will be distributed to its shareholders, in proportion to their holdings in the Municipal Bond Fund, and the Municipal Bond Fund will be terminated as soon as reasonably practicable thereafter. (All of these transactions are referred to below collectively as the "reorganization.") 2. WHAT WILL HAPPEN TO MY SHARES OF THE MUNICIPAL BOND FUND AS A RESULT OF THE REORGANIZATION? Your shares of the Municipal Bond Fund will, in effect, be exchanged on a tax-free basis for shares of a similar class of the Municipal Income Fund with an equal total net asset value. The Municipal Bond Fund will then be terminated. 3. WHY IS THE REORGANIZATION BEING PROPOSED, AND WHAT ARE THE BENEFITS OF MERGING THE MUNICIPAL BOND FUND INTO THE MUNICIPAL INCOME FUND? The reorganization is designed to reduce existing overlap in funds within the same asset class offered within the MFS fund family, thereby reducing inefficiencies and creating a larger combined fund. The Trustees believe that the reorganization is in the best interest of each Fund's shareholders and that the interests of shareholders will not be diluted as a result of the reorganization. The reorganization would provide you with the opportunity to participate in a somewhat larger combined fund with a similar investment objective and similar policies and strategies, potentially lower expenses resulting from fixed costs being spread over a somewhat larger asset base, a generally better historical performance record, and greater prospects for asset growth over time. In addition, combining the Funds will likely eliminate the duplication of certain services and expenses that currently exist as a result of their separate operations, which could promote more efficient management and operations on a more cost-effective basis. As shown in more detail below, the two Funds have substantially similar investment objectives, policies and strategies, but the Municipal Income Fund has a more diversified portfolio of investments. It is estimated that if the reorganization is completed, each class of the combined fund will have a slightly lower expense ratio than the current expense ratio of the corresponding class of the Municipal Bond Fund (by an estimated 0.01% for each class). In addition, although past performance is not an indication of future performance, Municipal Income Fund generally has a better historical performance record than the Municipal Bond Fund. It is expected that the reorganization will be a tax-free event for federal income tax purposes and, accordingly, no gain or loss will be recognized by you or the Municipal Bond Fund as a direct result of the reorganization. For a complete discussion of the factors considered by the Board of Trustees in approving the reorganization, please see "Background and Reasons for the Proposed Reorganization" below. 4. HOW DO THE INVESTMENT OBJECTIVES, PRINCIPAL INVESTMENT STRATEGIES, POLICIES AND RESTRICTIONS OF THE TWO FUNDS COMPARE? The investment objectives of the two Funds are similar. Municipal Bond Fund's investment objective is to seek total return with an emphasis on income exempt from federal income tax, but also considering capital preservation. Municipal Income Fund's investment objective is to provide as high a level of current income exempt from federal income taxes as is considered consistent with prudent investing while seeking protection of shareholders' capital.(1) Both Funds' investment objectives can be changed without shareholder approval. Both Funds seek to achieve their respective objective by investing, under normal market conditions, at least 80% of their respective net assets in securities and other investments, the interest on which is exempt from federal income tax. Investment by the Funds in municipal securities, which include bonds or other debt obligations of a U.S. state or political subdivision, such as a county, city, town, village, or authority, satisfies this policy. Both Funds also may invest in participation interests in municipal securities, which are interests in holdings of municipal obligations backed by a letter of credit or guarantee from the issuing bank. While each fund seeks to invest in municipal securities whose income is exempt from federal income tax, the interest income on certain of these municipal securities may be subject to alternative minimum tax. ----------- (1) Although the Funds currently have slightly different investment objectives, the Board of Trustees of Municipal Income Fund has approved changes to the Fund's investment objective that will make the Municipal Income Fund's investment objective identical to Municipal Bond Fund's current investment objective. This change will become effective August 1, 2007 in connection with the Municipal Income Fund's annual prospectus update. Both Funds focus on municipal securities rated, or issued by issuers who have securities that are rated, in one of the top four credit ratings by credit rating agencies. Each Fund may invest in speculative securities, which are securities rated in the lowest investment grade category. Municipal Income Fund (but not Municipal Bond Fund) may invest as part of its principal investment strategies in lower rated bonds, commonly known as junk bonds, which are bonds assigned credit ratings below the four highest credit ratings by credit rating agencies or which are unrated and considered by MFS to be comparable to lower rated bonds. On the other hand, Municipal Bond Fund generally invests substantially all of its assets in investment grade debt securities. As of [___, 2006], the average credit quality of rated securities held in Municipal Bond Fund's portfolio was __, compared to __ for Municipal Income Fund. In addition to the Funds' principal investment strategies referred to above, the Funds may engage in a number of other investment techniques and practices. The investment techniques and practices employed by each Fund, together with their risks, are described in each Fund's Prospectus. For more information regarding each Fund's investment policies and restrictions, see, among other disclosures, "Certain Investment Strategies and Risks" and "Appendix A - Investment Techniques and Practices" in Municipal Income Fund's current prospectus, "Investment Techniques, Practices, Risks and Restrictions" in Part I of each Fund's current Statement of Additional Information, "Appendix C - Investment Techniques and Practices," and "Appendix F - Investment Restrictions" in Part II of each Fund's current Statement of Additional Information. 5. HOW DO THE MANAGEMENT FEES AND OTHER EXPENSES OF THE TWO FUNDS COMPARE, AND WHAT ARE THEY ESTIMATED TO BE FOLLOWING THE REORGANIZATION? Management Fees. The table on page [ ] shows the annual operating expenses of the Funds. With respect to both Funds, MFS has agreed in writing to reduce its management fee to 0.30% annually of the fund's average daily net assets. MFS has agreed in writing to maintain these management fee reductions until February 28, 2009, as part of its settlement with the New York Attorney General concerning market timing and related matters (the "NYAG Settlement"). For the twelve-month period ended September 30, 2006, each Fund paid an effective management fee rate of 0.30% annually of its average daily net assets after taking into account these management fee reductions. The annual management fee rate set forth in each Fund's Investment Advisory Agreement with MFS based on the average daily net assets of the Fund is as follows: MUNICIPAL BOND FUND FUND ASSET BREAKPOINTS FEE RATE First $1.3 billion 0.40% Amount over $1.3 billion and up to $2.0 billion 0.37% Amount in excess of $2.0 billion 0.35% MUNICIPAL INCOME FUND FEE RATE ALL ASSET LEVELS 0.55% If the reorganization is consummated, after the expiration of the NYAG Settlement on February 28, 2009 MFS will agree to impose Municipal Bond Fund's lower contractual management fee schedule, as described above, effective March 1, 2009. This agreement could only be modified or rescinded upon approval of Municipal Income Fund's Board of Trustees. Thus, the contractual and effective management fee rates for the Municipal Income Fund after giving effect to the reorganization would remain equal to those of the Municipal Bond Fund. Sales Charges and Rule 12b-1 Fees. The sales charges are the same for both Funds; however, no initial sales charge will be charged to shareholders in connection with the reorganization of the Funds. The contingent deferred sales charge aging schedule for Class B shares of Municipal Bond Fund will be carried over to Class B1 shares of Municipal Income Fund obtained in the reorganization. In addition, the maximum amounts payable under the Rule 12b-1 distribution plans, adopted pursuant to Rule 12b-1 under the 1940 Act, are the same for Class B shares of Municipal Bond Fund and Class B1 shares of Municipal Income Fund. Further, Class B shares of Municipal Bond Fund and Class B1 shares of Municipal Income Fund are subject to similar expense limitations on Rule 12b-1 fees. Neither Class A shares of Municipal Bond Fund nor Class A1 shares of Municipal Income Fund are subject to Rule 12b-1 fees. Other Expenses and Total Annual Fund Expenses. The Class A1 and Class B1 shares of the Municipal Income Fund to be issued to shareholders of the Municipal Bond Fund were recently created and will be issued solely in connection with this transaction. As a result, Class A1 and Class B1 shares did not incur any expenses during the Fund's most recent fiscal year. The Class A1 and Class B1 expenses discusses below reflect estimated Class A1 and Class B1 expenses based on the Municipal Income Fund's operating expenses for the twelve- month period ended September 30, 2006, adjusted to reflect the Class A1 and Class B1 expense structure. The Municipal Income Fund's estimated "Other Expenses" for Class A1 and Class B1 shares are 0.06% higher than the Municipal Bond Fund's "Other Expenses" for Class A and Class B shares, respectively, for the twelve-month period ended September 30, 2006. For the same period, the Municipal Income Fund's estimated "Total Annual Fund Expenses" for Class A1 and Class B1 shares were each 0.21% higher than those for the Municipal Bond Fund's Class A and Class B shares, respectively. For the same period, the Municipal Income Fund's estimated "Net Expenses" for Class A1 and Class B1 shares were each 0.06% higher than those for the Municipal Bond Fund's Class A and Class B shares, respectively. If the reorganization is approved, it is estimated that Class A1 and Class B1 shares of the combined fund will have a net annual expense ratio that is 0.01% lower than the net annual expense ratio for Class A and Class B shares of Municipal Bond Fund. In addition, if the reorganization is consummated, MFS will agree in writing to bear Municipal Income Fund's expenses such that "Net Expenses" do not exceed 0.49% for Class A1 shares and 1.25% for Class B1 shares for a period of one year from the closing date of the reorganization. This written agreement will exclude taxes, brokerage and transaction costs, currency conversion costs, extraordinary expenses, and expenses associated with the Fund's investing activities. The following tables summarize the maximum fees and expenses that you may pay when investing in the Funds, expenses that each Fund incurred in the twelve months ended September 30, 2006, and estimates of pro forma expenses of the Municipal Income Fund after giving effect to the reorganization (assuming that the reorganization occurred on October 1, 2005) CLASS A/ CLASS B/ CLASS A1 CLASS B1 SHARES SHARES --------- -------- SHAREHOLDER FEES (FEES PAID DIRECTLY FROM YOUR INVESTMENT) Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price) Municipal Bond Fund 4.75%* None Municipal Income Fund 4.75%*+ None Maximum Deferred Sales Charge (Load) (as a percentage of the original purchase price or redemption proceeds, whichever is less) Municipal Bond Fund See Below* 4.00%** Municipal Income Fund See Below* 4.00%** --------- + No sales charge will be paid on shares of the Municipal Income Fund issued in connection with this proposed reorganization. * For Class A and Class A1 shares only, an initial sales charge will not be deducted from your purchase if you buy $1 million or more of Class A or Class A1 shares, or if you are investing through a retirement plan and your Class A or Class A1 purchase meets certain requirements. However, in either case, a contingent deferred sales charge (referred to as a CDSC) of 1% may be deducted from your redemption proceeds if you redeem your investment within 12 months of your purchase. ** 4.00% in the first year, declining to 1.00% in the sixth year, and eliminated thereafter.

The maximum Rule 12b-1 fee for Class B shares of Municipal Bond Fund and Class B1 shares of Municipal Income Fund is 1.00% (consisting of a 0.75% distribution fee and a 0.25% service fee). With respect to Class B shares of Municipal Bond Fund and Class B1 shares of Municipal Income Fund, for one year from the date of sales of shares, assets attributable to such shares are subject to a 0.25% per annum service fee. On assets attributable to all other Class B or Class B1 shares, the service fee is not currently in effect, but may be implemented on such date as the Funds' board of trustees may determine. Class A shares of Municipal Bond Fund and Class A1 shares of Municipal Income Fund are not subject to a Rule 12b-1 distribution and service fee. (2) Each Fund had an expense offset agreement that reduces that Fund's custodian fee based upon the amount of cash maintained by the Fund with its custodian and dividend disbursing agent and may have entered into brokerage arrangements that reduced or recaptured fund expenses. Any such fee reductions are not reflected in the table. (3) With respect to each Fund, MFS has agreed in writing to waive its management fee to 0.30% annually. MFS has agreed in writing to maintain this management fee reduction until February 28, 2009, as part of the NYAG Settlement. With respect to the Municipal Income Fund, if the reorganization is consummated and if the management fee reduction resulting from the NYAG Settlement is not extended beyond February 28, 2009, MFS has agreed to impose Municipal Bond Fund's lower contractual management fee schedule effective March 1, 2009. This agreement will remain in place until modified by Municipal Income Fund's Board of Trustees. In addition, if the reorganization is consummated, MFS will agree in writing to bear Municipal Income Fund's expenses such that "Net Expenses" do not exceed 0.49% for Class A1 shares and 1.25% for Class B1 shares for a period of one year from the closing date of the reorganization. This written agreement will exclude taxes, brokerage and transaction costs, currency conversion costs, extraordinary expenses, and expenses associated with the Fund's investing activities. (4) Expenses estimated based on Municipal Income Fund's operating expenses for the twelve-month period ended September 30, 2006 and adjusted to reflect Class A1 and Class B1 expense structure, respectively. (5) The Municipal Bond Fund has a fiscal year end of August 31 and the Municipal Income Fund has a fiscal year end of March 31. Expenses computed for Municipal Bond Fund for the Municipal Income Fund's twelve month period ended September 30, 2006. (6) Assumes that the reorganization occurred on October 1, 2005.
The above tables are provided to help you understand the expenses of investing in the Funds, including estimates of pro forma expenses of the Municipal Income Fund after giving effect to the reorganization, and your share of the operating expenses that each Fund incurs. EXAMPLES The following examples translate the expense percentages shown in the preceding tables into dollar amounts. By doing this, you can more easily compare the cost of investing in the Funds. The examples make certain assumptions. They assume that you invest $10,000 in a Fund for the time periods shown and that you redeem all your shares at the end of these periods (unless otherwise indicated below). They also assume a 5% return on your investment each year and that dividends and other distributions are reinvested. They also assume that a Fund's operating expenses remain the same, except that a Fund's total operating expenses are assumed to be the Fund's "Net Expenses" for the period during which any contractual fee reductions are in effect. The examples are hypothetical; your actual costs and returns may be higher or lower. 1 YEAR 3 YEARS 5 YEARS 10 YEARS ------ ------- ------- --------- MUNICIPAL BOND Class A $ 523 $ 631 $ 765 $ 1,155 Class B(1) Assuming redemption at end of period $ 527 $ 703 $ 915 $ 1,393 Assuming no redemption $ 127 $ 403 $ 715 $ 1,393 MUNICIPAL INCOME Class A1 $ 529 $ 658 $ 839 $ 1,362 Class B1(2) Assuming redemption at end of period $ 533 $ 731 $ 990 $ 1,597 Assuming no redemption $ 133 $ 431 $ 790 $ 1,597 MUNICIPAL INCOME (PRO FORMA COMBINED) Class A1 $ 522 $ 628 $ 760 $ 1,143 Class B1(2) Assuming redemption at end of period $ 526 $ 700 $ 910 $ 1,381 Assuming no redemption $ 126 $ 400 $ 710 $ 1,381 (1) Class B shares convert to Class A shares approximately eight years after purchase. Therefore, years nine and ten reflect Class A expenses. (2) Class B1 shares convert to Class A1 shares approximately eight years after purchase. Therefore, years nine and ten reflect Class A1 expenses. For more information on the fees and expenses of each Fund, see "Expense Summary" in each Fund's current Prospectus. 6. HOW HAS THE MUNICIPAL INCOME FUND PERFORMED? As shown in the tables below, the Municipal Income Fund [outperformed Class A and Class B shares of the Municipal Bond Fund for the 1-Year, 5-Year, and 10-Year periods ended December 31, 2006 and Class A shares of Municipal Income Fund outperformed Class A shares of Municipal Bond Fund in seven of the last ten calendar years.] Because Municipal Income Fund's Class A1 and Class B1 shares have not yet commenced operations, these classes do not have a performance record to report. As a result, Class A and Class B share average annual total returns for Municipal Income Fund are reported below. Although Class A1 and Class B1 shares of Municipal Income Fund would have similar returns (because they represent interests in the same portfolio of securities), Class A1 and Class B1 performance would differ to the extent that Class A1 and Class B1 have lower expenses than Class A and Class B shares of Municipal Income Fund, respectively.

WHAT ARE THE DIFFERENCES IN PORTFOLIO TURNOVER RATES OF THE TWO FUNDS? Portfolio turnover is a measure of how frequently a Fund trades portfolio securities. Frequent trading of portfolio securities increases transaction costs, which could detract from a Fund's performance. Additionally, active and frequent trading may result in the realization and distribution to a Fund of higher capital gains, which would increase the tax liability for the Fund's shareholders who do not hold shares in tax-free accounts such as a 401(k) plan. The difference in portfolio turnover rates between the Funds is minimal. During each Fund's respective most recent fiscal year, Municipal Bond Fund had a portfolio turnover rate of 12% and Municipal Income Fund had a portfolio turnover rate of 9%. 8. WHO MANAGES THE MUNICIPAL INCOME FUND? The Municipal Income Fund is managed by Geoffrey L. Schechter, an MFS Senior Vice President. Mr. Schechter also currently manages the Municipal Bond Fund. Mr. Schechter has been a portfolio manager of the Municipal Bond Fund since 1998 and of the Municipal Income Fund since 2000, and has been employed in the investment management area of MFS since 1993. 9. HOW WILL THE REORGANIZATION HAPPEN? If the reorganization is approved, your Municipal Bond Fund shares will be effectively exchanged for Municipal Income Fund shares, using the Funds' respective net asset value per share prices, excluding sales charges, as of the close of trading on or about March 16, 2007. This exchange will not affect the total dollar value of your investment. 10. WILL THE REORGANIZATION HAVE TAX CONSEQUENCES? It is expected that the reorganization itself will be a tax-free event for federal income tax purposes. Accordingly, no gain or loss will be recognized by you or the Municipal Bond Fund as the direct result of the reorganization and your aggregate tax basis in the Municipal Income Fund shares you will receive in connection with the reorganization will be the same as your aggregate tax basis in your Municipal Bond Fund shares. That said, because the reorganization will cause the Municipal Bond Fund's tax year to end on a date earlier than the last day of its normal tax year, it may accelerate distributions from that Fund to its shareholders. In particular, the Municipal Bond Fund will recognize net gains or losses on the sales of any securities, net of any available capital loss carryforwards, in the short period ending on the closing date, and on or before that date it must declare a dividend paying out any such net gains to shareholders. Also, to the extent that the Municipal Bond Fund holds any securities that are marked to market in connection with the reorganization, it will also recognize and be required to pay out any net gain from such securities. At any time prior to the consummation of the reorganization, you may redeem shares, which will likely result in the recognition of gain or loss for federal income tax purposes. For more information about the federal income tax consequences of the reorganization, see "Federal Income Tax Consequences" below. 11. WILL MY DIVIDEND BE AFFECTED BY THE REORGANIZATION? Currently, the Municipal Bond Fund intends to declare daily as dividends substantially all of its net investment income (excluding any capital gains) and to pay these dividends to shareholders at least monthly. Any capital gains are distributed at least annually. Distributions by the Municipal Bond Fund may be accelerated prior to the reorganization, as described above. Following the reorganization, the payment frequency for dividends and capital gains in the Municipal Income Fund is the same as the Municipal Bond Fund's regular distribution schedule. Except as described below, your distributions will continue to be either reinvested or paid in cash, according to the option you selected with the Municipal Bond Fund. Of course, the amount of these dividends will reflect the investment performance of the Municipal Income Fund. The Municipal Income Fund will not permit any Municipal Bond Fund shareholder holding certificates for Municipal Bond Fund shares at the time of the reorganization to receive cash dividends or other distributions, to receive certificates for shares issued in the reorganization (referred to as "Reorganization Shares"), to exchange Reorganization Shares for shares of other investment companies managed by MFS, or to pledge or redeem Reorganization Shares until such certificates for Municipal Bond Fund shares have been surrendered, or, in the case of lost certificates, until an adequate surety bond has been posted. If a shareholder is not permitted to receive cash dividends or other distributions on Reorganization Shares for one of the reasons above, the Municipal Income Fund will pay all such dividends and distributions in additional shares, notwithstanding any election the shareholder may have made previously to receive dividends and distributions on Municipal Bond Fund shares in cash. 12. WHAT MUNICIPAL INCOME FUND SHARES WILL SHAREHOLDERS OF THE MUNICIPAL BOND FUND RECEIVE IF THE REORGANIZATION OCCURS? As noted above, shareholders holding Class A and Class B shares of the Municipal Bond Fund will receive newly-issued Class A1 and Class B1 shares, respectively, of the Municipal Income Fund in accordance with their percentage ownership of Class A and Class B shares of the Municipal Bond Fund. The Municipal Income Fund is a series of MFS Municipal Series Trust (the "Municipal Series Trust"), a voluntary association with transferable shares organized under the laws of The Commonwealth of Massachusetts (commonly referred to as a "Massachusetts business trust") and is governed by the Municipal Series Trust's Amended and Restated Declaration of Trust ("Municipal Series Trust's Declaration of Trust") and by-laws, as amended and restated. The Municipal Bond Fund is a series of MFS Series Trust IV, another Massachusetts business trust, and is governed by its Amended and Restated Declaration of Trust ("Series Trust IV's Declaration of Trust") and by-laws, as amended and restated. The Municipal Series Trust's and the Series Trust IV's Declarations of Trust are substantially similar, and their by laws are identical, to one another. Accordingly, shareholders of the Municipal Bond Fund will have substantially similar rights to those they currently have as shareholders of Municipal Bond Fund when they become shareholders of the Municipal Income Fund. In addition, both the Municipal Series Trust and the Series Trust IV are overseen by the same Board of Trustees. 13. DO THE PROCEDURES FOR PURCHASING, REDEEMING AND EXCHANGING SHARES OF THE TWO FUNDS DIFFER? Except as noted below, the procedures for purchasing and redeeming shares of each Fund, and for exchanging shares of each Fund for shares of other MFS Funds, are similar. Both Funds currently offer Class A and Class B shares. The Municipal Income Fund also offers Class A1, Class B1, and Class C shares. Shares of both Funds may be purchased through financial intermediaries that have sales agreements with MFS Fund Distributors, Inc. ("MFD") at prices based on net asset value, plus varying sales charges, depending on the class and number of shares purchased. Reinvestment of distributions by the Funds are made at net asset value for all classes. Shares of each Fund may be redeemed any day the New York Stock Exchange is open at their net asset value next determined after receipt by the Fund of a properly completed redemption request either directly from you or through a financial intermediary by the Fund's valuation time. Class A1 and Class B1 shares will be available only to shareholder accounts opened in the Municipal Income Fund in connection with Municipal Income Fund's acquisition of all the assets and certain stated liabilities of Municipal Bond Fund pursuant to the Agreement and Plan of Reorganization. Class A1 and Class B1 shareholders of Municipal Income Fund will be able to purchase additional Class A1 and Class B1 shares after the reorganization through accounts opened in connection with the reorganization. However, once a Class A1 or Class B1 shareholder has closed their account in Municipal Income Fund, they will be prohibited from purchasing Class A1 or Class B1 shares of the Municipal Income Fund in the future. Class A1 or Class B1 shares may be exchanged for shares for Class A or Class B shares, respectively, of certain other MFS funds at net asset value by having your financial intermediary process your exchange request or by contacting MFSC directly. However, exchanges of Class A or Class B shares of certain other MFS funds for Class A1 and Class B1 shares of Municipal Income Fund, respectively, will not be permitted. For more information on the principal share characteristics of the Funds, see "Description of Share Classes" and "How to Purchase, Exchange and Redeem Shares" in each Fund's current prospectus. 14. HOW WILL I BE NOTIFIED OF THE OUTCOME OF THE REORGANIZATION? If the proposed reorganization is approved by shareholders, you will receive confirmation after the reorganization is completed, indicating your new account number, the number of shares of the Municipal Income Fund you are receiving and the procedures for surrendering your certificates of the Municipal Bond Fund, if you have any. If the reorganization is not approved, the Municipal Bond Fund will continue to be managed as a separate fund in accordance with its current investment objectives and policies and the Trustees may consider other alternatives. 15. WILL THE NUMBER OF SHARES EACH SHAREHOLDER OWNS CHANGE? Yes, but the total value of the shares of the Municipal Income Fund you receive will equal the total value of the shares of the Municipal Bond Fund that you hold at the time of the reorganization. Even though the net asset value per share of each Fund (and the resulting number of shares) is different, the total value of your holdings will not change as a result of the reorganization. RISK FACTORS WHAT ARE THE PRINCIPAL RISK FACTORS ASSOCIATED WITH AN INVESTMENT IN THE MUNICIPAL INCOME FUND, AND HOW DO THEY COMPARE WITH THOSE FOR THE MUNICIPAL BOND FUND? Because the Funds share similar investment objectives and investment policies, the risks of an investment in the Municipal Income Fund are similar to the risks of an investment in the Municipal Bond Fund. While Municipal Income Fund has the ability to invest a greater portion of its assets in lower-rated municipal securities, each Fund has experienced a similar risk profile over the last three years. For example, as of September 30, 2006, the three-year standard deviation was 2.75% for the Municipal Income Fund versus 2.80% for the Municipal Bond Fund (a higher percentage for standard deviation reflects a higher risk profile). Each Fund, unless specified otherwise, is principally subject to the risks described below: Municipal Securities Risk: o Interest Rate Risk: As with any fixed income security, the prices of municipal securities in the fund's portfolio will generally fall when interest rates rise. Conversely, when interest rates fall, the prices of municipal securities in the fund's portfolio will generally rise. o Maturity Risk: Interest rate risk will generally affect the price of a municipal security more if the security has a longer maturity. Municipal securities with longer maturities will therefore be more volatile than other fixed income securities with shorter maturities. Conversely, municipal securities with shorter maturities will be less volatile but generally provide lower returns than municipal securities with longer maturities. The average maturity of the fund's municipal security investments will affect the volatility of the fund's share price. o Credit Risk: Credit risk is the risk that the issuer of a municipal security will not be able to pay principal and interest when due. Rating agencies assign credit ratings to certain municipal securities to indicate their credit risk. The price of a municipal security will generally fall if the issuer defaults on its obligation to pay principal or interest, the rating agencies downgrade the issuer's credit rating or other news affects the market's perception of the issuer's credit risk. A participation interest is also subject to the risk of default by the issuing bank. o General Obligations and Revenue Obligations Risk: The Fund may invest in municipal bonds that are general obligations backed by the full faith and credit of the municipal issuer. The Fund may also invest in municipal bonds called revenue obligations which are subject to a higher degree of credit risk than general obligations. Revenue obligations finance specific projects (such as building a hospital or toll roads, water and sewer projects, etc.), and are not backed by the full faith and credit of the municipal issuer. The Fund may invest in excess of 25% of its assets in revenue bonds relating to any one specific industry (e.g., housing, healthcare, water and sewer, etc.). Because revenue obligations are repaid from the revenues from a facility, they are subject to a risk of default in payments of principal and interest if the facility does not generate enough income. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues from the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline significantly in value. o Municipal Lease Obligations Risk: The Fund's investments in municipal securities may include municipal lease obligations. Municipal lease obligations are undivided interests issued by a state or municipality in a lease or installment purchase which generally relates to equipment or facilities. When the Fund invests in municipal lease obligations, it may have limited recourse in the event of default or termination. In some cases, payments under municipal leases do not have to be made unless the appropriate legislative body specifically approves money for that purpose. o Speculative Bonds Risk: Bonds rated in the lowest investment grade category (i.e., the fourth highest credit rating) by credit rating agencies are called speculative bonds. Speculative bonds are subject to a higher risk that the issuer will default on payments of principal and interest than higher rated investment grade bonds. Although the issuer's ability to make interest and principal payments appears adequate, an adverse change in economic conditions or other circumstances is more likely to cause a default by the issuer of a speculative bond than the issuer of a higher rated investment grade bond. o Liquidity Risk: The fixed income securities purchased by the Fund may be traded in the over-the-counter market rather than on an organized exchange and are subject to liquidity risk. This means that they may be harder to purchase or sell at a fair price. The inability to purchase or sell these fixed income securities at a fair price could have a negative impact on the Fund's performance. Junk Bond Risk: (Municipal Income Fund only) o Higher Credit Risk: Junk bonds (i.e. bonds rated below the four highest credit ratings) are subject to a substantially higher degree of credit risk than higher rated bonds. During recessions, a high percentage of issuers of junk bonds may default on payments of principal and interest. The price of a junk bond may therefore fluctuate drastically due to bad news about the issuer or the economy in general. o Higher Liquidity Risk: During recessions and periods of broad market declines, junk bonds could become less liquid, meaning that they will be harder to value or sell at a fair price. Other Investments. In addition to the Funds' main investment strategies described above, each Fund also may buy and sell the other types of investments. The risks associated with the principal investment techniques and practices used by the Funds are summarized above. The non-principal investment techniques in which the Funds may engage are described, together with their risks, in each Fund's Statement of Additional Information. As with any mutual fund, you could lose money on your investment in a Fund. An investment in a Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. For more information on the risks described above and other risks associated with each Fund, see, among other disclosures, "Risk Return Summary - Principal Risks of an Investment" and "Certain Investment Strategies and Risks - Further Information on Investment Strategies and Risks" in each Fund's current prospectus, "Investment Techniques, Practices, Risks and Restrictions" in Part I of each Fund's current Statement of Additional Information, and "Appendix C - Investment Techniques, Practices and Risks" in Part II of each Fund's current Statement of Additional Information. GENERAL This Prospectus/Proxy Statement is furnished in connection with the proposed reorganization of the Municipal Bond Fund into the Municipal Income Fund and the solicitation of proxies by and on behalf of the Trustees of the Municipal Bond Fund for use at the Special Meeting of Shareholders of the Municipal Bond Fund (the "Meeting"). The Meeting is to be held on March 7, 2007, at 2:00 p.m. at 500 Boylston Street, 24th floor, Boston, Massachusetts 02116. The Notice of the Meeting, the combined Prospectus/Proxy Statement and the enclosed proxy card are being mailed to shareholders on or about January 24, 2007. Any shareholder giving a proxy has the power to revoke it by mail (addressed to the Municipal Bond Fund's Assistant Secretary at the principal office of the Municipal Bond Fund, 500 Boylston Street, Boston, Massachusetts 02116) or in person at the Meeting, by executing a superseding proxy, or by submitting a notice of revocation to the Municipal Bond Fund. All properly executed proxies received in time for the Meeting will be voted as specified in the proxy, or, if no specification is made, FOR the proposal (set forth in Proposal 1 of the Notice of Meeting) to implement the reorganization of the Municipal Bond Fund as described below. As of January 17, 2007, Municipal Bond Fund had outstanding [ ], and [ ] of its Class A and Class B shares of beneficial interest, respectively. Only shareholders of record as of the close of business on January 17, 2007 will be entitled to notice of and to vote at the Meeting. Each shareholder is entitled to one vote for each dollar of net asset value of shares held by that shareholder on that date (i.e., number of shares times net asset value per share), with fractional dollar amounts voting proportionately. The Trustees of the Municipal Bond Fund know of no matters other than those set forth herein to be brought before the Meeting. If, however, any other matters properly come before the Meeting, it is the Trustees' intention that proxies will be voted on such matters in accordance with the judgment of the persons named in the enclosed form of proxy. PROPOSAL REGARDING APPROVAL OR DISAPPROVAL OF REORGANIZATION TRANSACTION AND RELATED AGREEMENT AND PLAN OF REORGANIZATION The shareholders of the Municipal Bond Fund are being asked to approve or disapprove a reorganization between the Municipal Bond Fund and the Municipal Income Fund pursuant to an Agreement and Plan of Reorganization between the Funds (the "Agreement"), a copy of the form of which is attached to this Prospectus/Proxy Statement as Appendix A. The reorganization is structured as a transfer of the assets and liabilities of the Municipal Bond Fund to the Municipal Income Fund in exchange for that number of full and fractional Class A1 and Class B1 Reorganization Shares, equal in total net asset value to the net value of assets transferred to the Municipal Income Fund, all as more fully described below under "Information About the Reorganization." After receipt of the Reorganization Shares, the Municipal Bond Fund will distribute the Class A1 Reorganization Shares to its Class A shareholders and the Class B1 Reorganization Shares to its Class B shareholders, each in proportion to their existing shareholdings, in complete liquidation of the Municipal Bond Fund, and the legal existence of the Municipal Bond Fund under Massachusetts law will be terminated as soon as reasonably practicable thereafter. Each shareholder of the Municipal Bond Fund will receive a number of full and fractional Class A1 and Class B1 Reorganization Shares equal in value at the date of the exchange to the aggregate value of the shareholder's Municipal Bond Fund shares of the same class. On or prior to the "Exchange Date" (as defined below), the Municipal Bond Fund will declare and pay a distribution to shareholders which, together with all previous distributions, will have the effect of distributing to shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized gains, if any, through the Exchange Date. The Trustees of the Municipal Bond Fund have voted unanimously to approve the proposed transaction and to recommend that shareholders also approve the transaction. The transactions contemplated by the Agreement will be consummated only if the Agreement is approved by the affirmative vote of the holders of the lesser of (a) 67% or more of the voting power of the securities present at the Meeting or represented by proxy if the holders of more than 50% of the outstanding voting power of the securities are present or represented by proxy or (b) more than 50% of the voting power of the outstanding voting securities of the Municipal Bond Fund. Shareholders of record are entitled to one vote for each dollar of net asset value of their shares (i.e., number of shares owned times net asset value per share), with fractional amounts voting proportionately. The reorganization does not require the approval of the shareholders of the Municipal Income Fund. In the event that this proposal is not approved by the shareholders of the Municipal Bond Fund, the Municipal Bond Fund will continue to be managed as a separate fund in accordance with its current investment objectives and policies and the Trustees may consider such alternatives as may be in the best interests of the Municipal Bond Fund and its shareholders. BACKGROUND AND REASONS FOR THE PROPOSED REORGANIZATION The Funds' Boards of Trustees, including all Trustees who are not "interested persons" of the Funds, have determined that the reorganization would be in the best interests of each Fund, and that the interests of existing shareholders of each Fund would not be diluted as a result of effecting the reorganization. The Trustees have unanimously approved the proposed reorganization and have recommended its approval by shareholders of the Municipal Bond Fund. The Municipal Income Fund and the Municipal Bond Fund have separate Boards of Trustees comprised of the same individuals. As discussed above, while not identical, the Municipal Income Fund and the Municipal Bond Fund have substantially similar investment objectives and policies. Municipal Bond Fund's investment objective is to seek total return with an emphasis on income exempt from federal income tax, but also considering capital preservation. Municipal Income Fund's investment objective is to provide as high a level of current income exempt from federal income taxes as is considered consistent with prudent investing while seeking protection of shareholders' capital.(2) ------------ (2) Although the Funds currently have slightly different investment objectives, the Board of Trustees of Municipal Income Fund has approved changes to the Fund's investment objective that will make the Municipal Income Fund's investment objective identical to Municipal Bond Fund's current investment objective. This change will become effective August 1, 2007 in connection with the Municipal Income Fund's annual prospectus update. In light of the similarity of the Funds, MFS advised the Board of Trustees of each Fund that it believes combining the Funds would be in the best interests of shareholders of both Funds and that the interests of each Fund's existing shareholders will not be diluted as a result of the proposed reorganization. The Board of Trustees of the Municipal Bond Fund believes that the proposed reorganization will be advantageous to the Municipal Bond Fund's shareholders for a number of reasons and considered the following matters, among others, in unanimously approving the proposal: 1. [The proposed reorganization offers Municipal Bond Fund's shareholders the opportunity to move their assets into another municipal bond fund that is more diversified as a result of its ability to invest in a broader range of municipal securities with respect to credit quality;] 2. The Funds have similar, but not identical, investment objectives, strategies, and restrictions; 3. The relative risks of investing in either Fund, including the somewhat higher risk profile of the Municipal Income Fund in comparison to the Municipal Bond Fund; 4. The reduction of overlap of similar funds within the MFS family of funds could reduce or eliminate portfolio and operational inefficiencies and will create a larger combined Fund with the potential for greater prospects for asset growth; 5. The pro forma total expense ratio for Class A1 and Class B1 shares (following the reorganization) of the Municipal Income Fund are estimated to be 0.01% lower than the corresponding Class A and Class B shares of the Municipal Bond Fund, based on expenses incurred for the twelve-month period ended September 30, 2006; 6. The effective management fees paid to MFS by each Fund are equal (giving effect to current management fee waivers) and MFS' agreement to impose Municipal Bond Fund's lower contractual management fee schedule effective upon the expiration of the NYAG Settlement; 7. The respective liabilities of each Fund; 8. The relative sizes of the Funds, and the possibility that the increased size of the combined Fund could, over time, provide the potential for lower expenses by spreading fixed expenses across a larger asset base; 9. Although past performance is not an indication of future results, the Municipal Income Fund generally has a better overall historical performance record than the Municipal Bond Fund; 10. The expectation that the transaction will qualify as a tax-free reorganization for federal income tax purposes, pursuant to which no gain or loss will be recognized by the Municipal Bond Fund or its shareholders for federal income tax purposes as a result of the transaction; 11. The fact that the combined fund will be managed by the same investment adviser, portfolio management team and portfolio manager who currently manage the Municipal Bond Fund; 12. The fact that the Class A and Class B shares of the Municipal Bond Fund have a structure that is substantially similar to that of the Class A1 and Class B1 shares, respectively, of Municipal Income Fund, including identical shareholder fees and Rule 12b-1 fees; 13. The compatibility of the Funds' shareholder service features; 14. The costs that will be borne directly or indirectly by each Fund in connection of the reorganization; 15. The fact that the combined fund's ability to use the Municipal Bond Fund's pre-reorganization capital loss carry forwards, if any, to offset future realized capital gains may be subject to certain limitations under the federal income tax laws; 16. The potential alternatives to the reorganization, including liquidation of the Municipal Bond Fund through the sale of the Fund's portfolio securities and distribution of the cash to its shareholders; and 17. The reorganization will not result in dilution of the interests of shareholders of either Fund. The Board of Trustees of the Municipal Income Fund considered that the reorganization presents an opportunity for the Municipal Income Fund to acquire investment assets without the need to pay brokerage commissions or other transaction costs that are normally associated with the purchase of securities. The Trustees also considered that the expenses the Municipal Income Fund would incur as a result of the reorganization were reasonable in relation to the benefits the Municipal Income Fund would realize as a result of the transaction. In addition, the Trustees considered that the Municipal Income Fund shareholders are expected to benefit from a decrease (estimated to be 0.07%) in the combined fund's expenses following the reorganization, as well as provide shareholders with the potential for further expense reductions over time as a result of fixed expenses being spread over a larger asset base (see "Synopsis, question 5" for a discussion of expenses). The Trustees also believe that the Municipal Income Fund shareholders could, over time, also benefit from improved diversification as a result of the reorganization. The Boards of Trustees of both Funds also considered that MFS could benefit from the reorganization. For example, MFS might realize time and cost savings from a consolidated portfolio management effort and from the need to prepare fewer reports and regulatory filings. Based on its review and the advice and recommendations of MFS, the Board of Trustees of each Fund has unanimously approved the proposal. Exchange without recognition of gain or loss for federal income tax purposes. If a Municipal Bond Fund shareholder were to redeem his or her shares to invest in another fund, such as the Municipal Income Fund, that shareholder would generally recognize gain or loss for federal income tax purposes. Also, if the Municipal Bond Fund were liquidated or reorganized in a taxable reorganization, the transaction would likely result in a taxable event for its shareholders. By contrast, the proposed reorganization will permit Municipal Bond Fund's shareholders to exchange their investment in that fund for an investment in the Municipal Income Fund without recognition of gain or loss for federal income tax purposes. After the reorganization, shareholders will be free to redeem any or all of the Municipal Income Fund shares they receive in the reorganization at net asset value (minus any applicable sales charge or redemption fee) at any time, at which point a taxable gain or loss would be recognized. INFORMATION ABOUT THE REORGANIZATION Agreement and Plan of Reorganization. The proposed reorganization will be governed by an Agreement and Plan of Reorganization (the "Agreement"). The Agreement provides that the Municipal Income Fund will acquire the assets and liabilities of the Municipal Bond Fund in exchange for the issuance of Class A1 and Class B1 Reorganization Shares equal in value to the value of the transferred assets net of assumed liabilities. The Reorganization Shares will be issued on March 16, 2007 (or such other date as may be agreed upon by the parties) following the time as of which the Funds' shares are valued for determining net asset value for the reorganization at the close of the New York Stock Exchange (generally 4:00 p.m. Eastern time) (the "Exchange Date). The following discussion of the Agreement is qualified in its entirety by the full text of the Agreement, a form of which is attached as Appendix A to this Prospectus/Proxy Statement. The Municipal Bond Fund will sell its assets to the Municipal Income Fund, and in exchange, the Municipal Income Fund will assume all liabilities of the Municipal Bond Fund and deliver to the Municipal Bond Fund (i) a number of full and fractional Class A1 Reorganization Shares having an aggregate net asset value equal to the value of assets of the Municipal Bond Fund attributable to its Class A shares, less the value of the liabilities of the Municipal Bond Fund assumed by the Municipal Income Fund attributable to such Class A shares; and (ii) a number of full and fractional Class B1 Reorganization Shares having a net asset value equal to the value of assets of the Municipal Bond Fund attributable to its Class B shares, less the value of the liabilities of the Municipal Bond Fund assumed by the Municipal Income Fund attributable to such Class B shares. On or as soon after the Exchange Date as is conveniently practicable, the Municipal Bond Fund will distribute to its shareholders of record as of the close of business on the Exchange Date, in proportion their holdings in the Municipal Bond Fund, the full and fractional Reorganization Shares received by the Municipal Bond Fund, with Class A1 Reorganization Shares being distributed to holders of Class A shares of the Municipal Bond Fund and Class B1 Reorganization Shares being distributed to holders of Class B shares of the Municipal Bond Fund. As a result of the proposed transaction, each holder of Class A and Class B shares of the Municipal Bond Fund will receive a number of Class A1 and Class B1 Reorganization Shares equal in aggregate net asset value to the net asset value of the Class A and Class B shares, respectively, of the Municipal Bond Fund held by the shareholder. This distribution will be accomplished by the establishment of accounts on the share records of the Municipal Income Fund in the name of such Municipal Bond Fund shareholders, each account representing the respective number of full and fractional Class A1 and Class B1 Reorganization Shares due such shareholder. New certificates for Reorganization Shares will not be issued, except in certain limited circumstances. The Trustees of each Fund have determined that the interests of the Fund's shareholders will not be diluted as a result of the transactions contemplated by the reorganization and that the proposed reorganization is in the best interests of each Fund. The consummation of the reorganization is subject to the conditions set forth in the Agreement. The Agreement may be terminated and the reorganization abandoned at any time, before or after approval by the shareholders by the mutual consent of the Municipal Bond Fund and the Municipal Income Fund. In addition, either Fund may at its option terminate the Agreement unilaterally at or prior to the Exchange Date because (i) of a material breach by the other party of any representation, warranty or agreement contained in the Agreement to be performed at or prior to the Exchange Date or (ii) a condition set forth in the Agreement expressed to be precedent to the obligations of the terminating Fund has not been fulfilled (or waived by the terminating Fund) and it reasonably appears that the condition will not or cannot be met. The fees and expenses for the transaction are estimated to be approximately $165,000. Each Fund shall bear its own fees and expenses, including legal and accounting expenses, portfolio transfer taxes (if any) and other similar expenses incurred in connection with the consummation of the transactions contemplated by the Agreement. Description of the Reorganization Shares. Reorganization Shares will be issued to the Municipal Bond Fund's shareholders in accordance with the procedures under the Agreement as described above. The Reorganization Shares are Class A1 and Class B1 shares of the Municipal Income Fund. Investors purchasing Class A1 shares pay a sales charge at the time of purchase, but Municipal Bond Fund shareholders receiving Class A1 Reorganization Shares in the reorganization will not pay a sales charge on such shares. Class A1 shares of the Municipal Income Fund are not subject to a Rule 12b-1 fee. Class B1 shares of the Municipal Income Fund are sold without a sales charge at the time of purchase, but may be subject to a CDSC of up to 4% if redeemed within six years of purchase. For purposes of determining the CDSC payable on a post-reorganization redemption of Class B1 Reorganization Shares received by holders of Class B shares of the Municipal Bond Fund, such shares will be treated as having been acquired as of the dates such shareholders originally acquired their Class B shares of the Municipal Bond Fund. Class B1 shares of the Municipal Income Fund are also subject to a maximum Rule 12b-1 fee of 1.00% of the Fund's average daily net assets attributable to Class B1 shares (consisting of a 0.75% distribution fee and 0.25% service fee). For one year from the date of sale of Class B1 shares, assets attributable to such shares are subject to the 0.25% service fee. The service fee on Class B1 shares is not currently imposed on shares held longer than one year, but may be implemented on such date as the Municipal Income Fund's board of trustees may determine. Class B1 shares will automatically convert to Class A1 shares, based on relative net asset value, approximately eight years after purchase. For purposes of determining the conversion date of Class B1 Reorganization Shares received by holders of Class B shares of the Municipal Bond Fund, such shares will be treated as having been acquired as of the dates such shareholders originally acquired their Class B shares of the Municipal Bond Fund. Each of the Reorganization Shares will be fully paid and nonassessable when issued, will be transferable without restriction, and will have no preemptive or conversion rights, except that Class B Reorganization Shares will have the conversion rights specified above. The Declaration of Trust of the Municipal Income Fund permits the Fund to divide its shares, without shareholder approval, into two or more classes of shares having such preferences and special or relative rights and privileges as the Trustees may determine. The Municipal Income Fund's shares are currently divided into five classes -- Class A, Class B, Class C, Class A1 and Class B1. Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Municipal Income Fund. However, the Declaration of Trust disclaims shareholder liability for acts or obligations of the Municipal Income Fund and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Municipal Income Fund or its Trustees. The Declaration of Trust provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Municipal Income Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Municipal Income Fund would be unable to meet its obligations. The likelihood of such circumstances is remote. The shareholders of the Municipal Bond Fund are subject to this same risk of shareholder liability. Federal Income Tax Consequences. As a condition to each Fund's obligation to consummate the reorganization, each Fund will receive an opinion from Ropes & Gray LLP, counsel to the Funds (which opinion will be based on certain factual representations and assumptions and subject to certain qualifications), substantially to the effect that, [although not free from doubt,] on the basis of the existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and current administrative rules and court decisions, for federal income tax purposes, except as noted below: (a) the reorganization will constitute a "reorganization" within the meaning of Section 368(a) of the Code, and the Municipal Income Fund and Municipal Bond Fund will each be a "party to a reorganization" within the meaning of Section 368(b) of the Code; (b) under Section 361 of the Code, no gain or loss will be recognized by the Municipal Bond Fund upon the transfer of its assets to the Municipal Income Fund in exchange for Reorganization Shares and the assumption by the Municipal Income Fund of the Municipal Bond Fund's liabilities, or upon the distribution of the Reorganization Shares by the Municipal Bond Fund to its shareholders in liquidation; (c) under Section 354 of the Code, no gain or loss will be recognized by shareholders of the Municipal Bond Fund on the distribution of Reorganization Shares to them in exchange for their shares of the Municipal Bond Fund; (d) under Section 358 of the Code, the aggregate tax basis of the Reorganization Shares that the Municipal Bond Fund's shareholders receive in exchange for their Municipal Bond Fund shares will be the same as the aggregate tax basis of the Municipal Bond Fund shares exchanged therefor; (e) under Section 1223(1) of the Code, a Municipal Bond Fund shareholder's holding period for the Reorganization Shares received pursuant to the Agreement will be determined by including the holding period for the Municipal Bond Fund shares exchanged for the Reorganization Shares, provided that the shareholder held the Municipal Bond Fund shares as a capital asset; (f) under Section 1032 of the Code, no gain or loss will be recognized by the Municipal Income Fund upon receipt of the assets transferred to the Municipal Income Fund pursuant to the Agreement in exchange for the Reorganization Shares and the assumption by the Municipal Income Fund of the liabilities of the Municipal Bond Fund; (g) under Section 362(b) of the Code, the Municipal Income Fund' tax basis in the assets that the Municipal Income Fund receives from the Municipal Bond Fund will be the same as the Municipal Bond Fund's tax basis in such assets immediately prior to such exchange; (h) under Section 1223(2) of the Code, the Municipal Income Fund's holding periods in such assets will include the Municipal Bond Fund's holding periods in such assets; and (i) under Section 381 of the Code, the Municipal Income Fund will succeed to the capital loss carryovers of the Municipal Bond Fund, if any, but the use by the Municipal Income Fund of any such capital loss carryovers (and of capital loss carryovers of the Municipal Income Fund) may be subject to limitation under Section 381, 382, 383 and 384 of the Code. The opinion will be based on certain factual certifications made by officers of MFS Series Trust IV, on behalf of the Municipal Bond Fund, and by officers of the Municipal Series Trust, on behalf of the Municipal Income Fund, and will also be based on customary assumptions. Notwithstanding the above, Ropes & Gray LLP will express no view with respect to the effect of the reorganization on any transferred asset as to which any unrealized gain or loss is required to be recognized for federal income tax purposes at the end of a taxable year (or on the termination or transfer thereof) under federal income tax principles. Each Fund has agreed to make and provide additional representations to tax counsel with respect to each Fund that are reasonably requested by tax counsel. A Fund may not waive in any material respect the receipt of the tax opinions as a condition to confirmation and to the reorganization. Prior to the Exchange Date, the Municipal Bond Fund will declare a distribution to shareholders, which together with all previous distributions, will have the effect of distribution to shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized capital gains, if any, through the Exchange Date. This description of the federal income tax consequences of the reorganization is made without regard to the particular facts and circumstances of any shareholder. Shareholders are urged to consult their own tax advisers as to the specific consequences to them of the reorganization, including the applicability and effect of state, local, non-U.S. and other tax laws. Additional Tax Considerations. As of October 31, 2006, the Municipal Bond Fund had no capital loss carryovers. Capital loss carryovers are used to reduce the amount of realized capital gains that a Fund is required to distribute to its shareholders in order to avoid paying taxes on undistributed capital gain. The ability of the Municipal Income Fund, as the surviving combined fund, to use its own pre-reorganization capital loss carryovers to offset future realized capital gains may be subject to an annual limitation under applicable tax laws if the reorganization occurs. Other tax rules would prohibit the use of one Fund's pre-reorganization capital loss carryovers against the other Fund's "built-in gains" (i.e., net unrealized gains). The effect of these limitations will depend on the amount of losses and "built-in gains" in each Fund at the time of the reorganization. For example, if the reorganization had occurred on October 31, 2006, the combined fund would have had net losses (i.e., capital loss carryforwards as of the end of the last fiscal year as adjusted by year-to-date realized gains or losses) of .287% of its net assets available to reduce capital gains, whereas absent the reorganization, the Municipal Income Fund would have net losses equal to 1.268% of its net assets available to reduce capital gains. As a result of the loss limitation and the spreading of the losses remaining available over a larger asset base, the percentage of losses available to offset capital gains would have decreased by .981% with respect to the Municipal Income Fund. As of October 31, 2006, both Funds had "built-in gains" and therefore, if the reorganization had occurred on that date, the prohibition on the use of capital loss carryforwards to offset such gains would apply. The application of these rules may accelerate taxable gain distributions to shareholders of the combined fund. Capitalization. The following table shows the capitalization of the Funds as of September 30, 2006, and on a pro forma combined basis, giving effect to the proposed acquisition of assets at net asset value as of that date:
MUNICIPAL MUNICIPAL PRO FORMA INCOME BOND PRO FORMA COMBINED FUND FUND ADJUSTMENTS FUND (B) --------- --------- ----------- ---------- Net assets (000's omitted) Class A1 -- $1,024,624 $ (123)(a) $1,024,501 Class B1 -- $ 42,246 $ (5)(a) $ 42,241 Shares outstanding (000's omitted) Class A1 -- 97,134 119,142 (b) 119,142 Class B1 -- 4,009 4,907 (b) 4,907 Net asset value per share Class A1 -- $10.55 -- $ 8.60 Class B1 -- $10.54 -- $ 8.61 ------------- (a) Amount reflects estimated reorganization costs. (b) If the reorganization had taken place on September 30, 2006, the Municipal Bond Fund would have received 119,142,356 and 4,906,616 shares for Classes A1 and B1, respectively, of the Municipal Income Fund, which would be available for distribution to its shareholders. No assurances can be given as to the number of Reorganization Shares the Municipal Bond Fund will receive on the Exchange Date. The foregoing is merely an example of what the Municipal Income Fund would have received and distributed had the reorganization been consummated on September 30, 2006, and should not be relied upon to reflect the amount that will be actually received on or after the Exchange Date.
Unaudited pro forma combined financial statements of the Funds as of September 30, 2006 and for the twelve-month period then ended are included in the Statement of Additional Information relating to the proposed reorganization. Because the Agreement provides that the Municipal Income Fund will be the surviving Fund following the reorganization and because the Municipal Income Fund's investment objectives and policies will remain unchanged, the pro forma combined financial statements reflect the transfer of the assets and liabilities of the Municipal Bond Fund to the Municipal Income Fund as contemplated by the Agreement. THE TRUSTEES OF THE MUNICIPAL BOND FUND, INCLUDING THE INDEPENDENT TRUSTEES, UNANIMOUSLY RECOMMEND APPROVAL OF THE PLAN. VOTING INFORMATION Required Vote. Proxies are being solicited from the Municipal Bond Fund's shareholders by its Trustees for the Meeting to be held on March 7, 2007 at 2:00 p.m. at 500 Boylston St., 24th Floor, Boston, Massachusetts 02116, or at such later time made necessary by adjournment. Unless revoked, all valid proxies will be voted in accordance with the specification thereon or, in the absence of specifications, FOR approval of the Agreement. The transactions contemplated by the Agreement will be consummated only if approved by the affirmative vote of a "majority of the outstanding voting securities" of the Municipal Bond Fund entitled to vote. Under the 1940 Act, the vote of a "majority of the outstanding voting securities" means the affirmative vote of the lesser of (a) 67% or more of the voting power of the securities present at the Meeting or represented by proxy if the holders of more than 50% of the outstanding voting power of the securities are present or represented by proxy or (b) more than 50% of the voting power of the outstanding voting securities. When shares of the Municipal Bond Fund are held jointly by two or more persons, any one of them may vote at the Meeting in person or by proxy in respect to such shares. A proxy shall be valid if executed by any one of the joint owners. Record Date, Quorum and Method of Tabulation. Shareholders of record of the Municipal Bond Fund at the close of business on January 17, 2007 (the "record date") will be entitled vote at the Meeting or any adjournment thereof. The holders of a majority of the voting power of the shares of the Municipal Bond Fund outstanding at the close of business on the record date present in person or represented by proxy will constitute a quorum for the Meeting. Shareholders of record are entitled to one vote for each dollar of net asset value of the shares (i.e., number of shares owned times net asset value per share), with fractional amounts voting proportionately. Votes cast by proxy or in person at the Meeting will be counted by persons appointed by the Municipal Bond Fund as the vote tabulator for the Meeting. The vote tabulator will count the total number of votes cast "for" approval of the proposal for purposes of determining whether sufficient affirmative votes have been cast. The vote tabulator will count shares represented by proxies that are marked with an abstention or that reflect "broker non-votes" (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owner or the persons entitled to vote and (ii) the broker or nominee does not have discretionary voting power on a particular matter) as shares that are present and entitled to vote on the matter for purposes of determining the presence of a quorum. Thus, abstentions and broker non-votes have the effect of a negative vote on the proposal. As of the record date, the officers and Trustees, as a group, beneficially owned less than 1% of any class of the outstanding shares of the Municipal Bond Fund. To the best of the knowledge of the Municipal Bond Fund, as of the record date, the following shareholders owned of record or beneficially 5% or more of the following classes of the Municipal Bond Fund's outstanding shares: SHAREHOLDER PRO FORMA NAME AND PERCENTAGE PERCENTAGE CLASS ADDRESS OWNED OWNED* ----------------------------------- ----------- --------- ---------- [To be updated] -------------- * Percentage owned assuming completion of the reorganization on , 2006. ** Believed to be a record owner. *** Believed to be a beneficial owner. The votes of the shareholders of the Municipal Income Fund are not being solicited because their approval or consent is not necessary for this transaction. As of the record date, the officers and Trustees of the Municipal Income Fund, as a group, beneficially owned less than 1% of any class of the outstanding shares of the Municipal Income Fund. To the best of the knowledge of the Municipal Income Fund, as of the record date, the following shareholders owned of record or beneficially 5% or more of the following classes of the Municipal Income Fund: SHAREHOLDER PRO FORMA NAME AND PERCENTAGE PERCENTAGE CLASS ADDRESS OWNED OWNED* ----------------------------------- ----------- --------- ---------- [To be updated] ------------- * Percentage owned assuming completion of the reorganization on , 2007. ** Believed to be a record owner. *** Believed to be a beneficial owner. Solicitation of Proxies. In addition to soliciting proxies by mail, the Trustees and employees of MFS, MFS Distributors, Inc. ("MFD") and MFS Service Center, Inc. may solicit proxies in person or by telephone. In addition, the Municipal Bond Fund has retained at its own expense [SOLICITOR] to aid in the solicitation of instructions for nominee and registered accounts for a fee of approximately $__,000, plus reasonable out-of-pocket expenses for proxy solicitation services, which will be paid by the Municipal Bond Fund. The Municipal Bond Fund may also arrange to have votes recorded by telephone. The telephonic voting procedure is designed to authenticate shareholders' identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions and to confirm that their instructions have been properly recorded. Shareholders would be asked for their Social Security numbers or other identifying information. The shareholders would then be given an opportunity to authorize their proxies to vote their shares in accordance with their instructions. To ensure that the shareholders' instructions have been recorded correctly, they will also receive a confirmation of their instructions in the mail. A toll-free number will be available in the event the information in the confirmation is incorrect. Shareholders have the opportunity to vote via the Internet as directed on your proxy card. The giving of such a proxy will not affect your right to vote in person should you decide to attend the Meeting. To vote via the Internet, you will need the "control" number that appears on your proxy card. The Internet voting procedures are designed to authenticate shareholder identities, to allow shareholders to give their voting instructions, and to confirm that shareholders' instructions have been recorded properly. Shareholders voting via the Internet should understand that there may be costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, that must be borne by the shareholders. Persons holding shares as nominees will upon request be reimbursed by the Municipal Bond Fund for their reasonable expenses in soliciting instructions from their principals. Revocation of Proxies. Proxies, including proxies given by telephone or via the Internet, may be revoked at any time before they are voted, by a written revocation received by the Secretary of the Municipal Bond Fund or by properly executing a later-dated proxy or by attending the Meeting and voting in person. Shareholder Proposals. The Municipal Bond Fund does not hold annual shareholder meetings in any year in which the election of Trustees is not required to be acted upon by the Investment Company Act of 1940 Act. However, the Fund currently maintains a policy to hold a shareholder meeting at least every five years to elect Trustees. If the reorganization is not approved, any shareholder who wishes to submit a proposal to be considered by the Fund's shareholders at the next meeting of shareholders should send the proposal to Municipal Bond Fund, c/o Susan S. Newton, Assistant Secretary, at 500 Boylston Street, 20th Floor, Boston, Massachusetts 02116, so as to be received within a reasonable time before the Board of Trustees makes the solicitation relating to such meeting. The submission by a shareholder of a proposal for inclusion in the proxy materials does not guarantee that it will be included. Shareholder proposals are subject to certain requirements under the federal securities laws. Adjournment. If the necessary quorum to transact business or sufficient votes in favor of the proposal are not received by the time scheduled for the Meeting, the persons named as proxies may propose adjournments of the Meeting to permit further solicitation of proxies. Any adjournment will require the affirmative vote of a majority of the votes cast on the question in person or by proxy at the session of the Meeting to be adjourned. The persons named as proxies will vote in favor of such adjournment those proxies which they are entitled to vote in favor of the proposal. They will vote against any such adjournment those proxies required to be voted against the proposal. They will not vote any proxy that directs them to abstain from voting on the proposal. The Municipal Bond Fund pays the costs of any additional solicitation and of any adjourned session. MISCELLANEOUS INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS Deloitte & Touche LLP serves as Independent Registered Public Accounting Firm to both the Municipal Bond Fund and the Municipal Income Fund. The audited financial statements of the Municipal Bond Fund and the Municipal Income Fund for the fiscal years ended August 31, 2006 and March 31, 2006, respectively, included in the Funds' respective Statement of Additional Information, have been audited by Deloitte & Touche LLP, Independent Registered Public Accounting Firm, whose reports thereon are included in the respective Fund's Statements of Additional Information and in the Annual Reports to Shareholders for the fiscal years ended August 31, 2006 and March 31, 2006 respectively. The financial statements audited by Deloitte & Touche LLP have been incorporated by reference in reliance on their reports given on their authority as experts in auditing and accounting. AVAILABLE INFORMATION The Municipal Bond Fund and the Municipal Income Fund are each subject to the informational requirements of the Securities Exchange Act of 1934 and the 1940 Act, and in accordance with these laws, they each file reports, proxy material and other information with the SEC. Such reports, proxy material and other information can be inspected and copied at the Public Reference Room maintained by the SEC at 100 F Street, N.W., Washington D.C. 20549 and the public reference facilities at the SEC's Northeast and Midwest regional offices at 3 World Financial Center, Room 4300, New York, NY 10281 and 175 W. Jackson Boulevard, Suite 900, Chicago, IL 60604, respectively. Copies of such material can also be obtained from the Public Reference Branch, Office of Consumer Affairs and Information Services, Securities and Exchange Commission, Washington D.C. 20549, at prescribed rates, or at the SEC website (http://www.sec.gov). OTHER BUSINESS Management of the Municipal Bond Fund knows of no business other than the matters specified above that will be presented at the Meeting. Because matters not known at the time of the solicitation may come before the Meeting, the proxy as solicited confers discretionary authority with respect to such matters as properly come before the Meeting, including any adjournment or adjournments thereof, and it is the intention of the persons named as attorneys-in-fact in the proxy to vote this proxy in accordance with their judgment on such matters. LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding with the Securities and Exchange Commission ("SEC") regarding disclosure of brokerage allocation practices in connection with MFS fund sales (the term "MFS funds" means the open-end registered management investment companies sponsored by MFS). The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February 2004, MFS reached agreement with the SEC, the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire to settle administrative proceedings alleging false and misleading information in certain MFS open-end retail fund prospectuses regarding market timing and related matters. Since December 2003, MFS, MFD, MFS Service Center, Inc., MFS Corporation Retirement Committee, Sun Life Financial Inc., various MFS funds, certain current and/or former Trustees of the MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The various lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, and inadequately disclosed MFS' internal policies concerning market timing and such matters, (ii) received excessive compensation as fiduciaries with respect to the MFS funds, or (iii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of MFS fund shares and inadequately disclosed MFS' use of fund assets in this matter. The lawsuits assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974 (ERISA), as well as fiduciary duties and other violations of common law. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the MFS funds during specified periods, as ERISA actions by participants in certain retirement plan accounts on behalf of those accounts, or as derivative actions on behalf of the MFS funds. The lawsuits relating to market timing and related matters have been transferred to, and consolidated before, the United States District Court for the District of Maryland, as part of a multi-district litigation of market timing and related claims involving several other fund complexes (In re Mutual Funds Investment Litigation (Alger, Columbia, Janus, MFS, One Group, Putnam, Allianz Dresdner), No. 1:04-md-15863 (transfer began March 19, 2004)). The market timing cases related to the MFS funds include Riggs v. MFS et al., Case No. 04-CV-01162-JFM (direct), Hammerslough v. MFS et al., Case No. 04-MD-01620 (derivative), Anita Walker v. MFS et al., Case No. 1:04-CV-01758 (ERISA), and Reaves v. MFS Series Trust I, et al., Case No. 1:05-CV-02220-JFM (Class B Shares). The plaintiffs in these consolidated lawsuits generally seek injunctive relief including removal of the named Trustees, adviser and distributor, rescission of contracts and 12b-1 Plans, disgorgement of fees and profits, monetary damages, punitive damages, attorney's fees and costs and other equitable and declaratory relief. Two lawsuits alleging improper brokerage allocation practices and excessive compensation are pending in the United States District Court for the District of Massachusetts (Forsythe v. Sun Life Financial Inc., et al., No. 04cv10584 (GAO) (a consolidated action, first filed on March 25, 2004) and Marcus Dumond, et al. v. Massachusetts Financial Servs. Co., et al., No. 04cv11458 (GAO) (filed on May 4, 2004)). The plaintiffs in these lawsuits generally seek compensatory damages, punitive damages, recovery of fees, rescission of contracts, an accounting, restitution, declaratory relief, equitable and/or injunctive relief and attorney's fees and costs. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the MFS funds. Several claims of the various lawsuits have been dismissed; MFS and other named defendants continue to defend the various lawsuits. IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPLY. NOTICE TO BANKS, BROKER-DEALERS AND VOTING TRUSTEES AND THEIR NOMINEES. Please advise the Municipal Bond Fund, in care of MFS Service Center, Inc., 500 Boylston Street, Boston, MA 02116, whether other persons are beneficial owners of shares for which proxies are being solicited and, if so, the number of copies of the Proxy Statement you wish to receive in order to supply copies to the beneficial owners of the shares. January 24, 2007 MFS MUNICIPAL BOND FUND 500 Boylston Street Boston, MA 02116 APPENDIX A FORM OF AGREEMENT AND PLAN OF REORGANIZATION AGREEMENT AND PLAN OF REORGANIZATION THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made this __th day of December, 2006, by and between MFS Series Trust IV, a Massachusetts business trust ("Trust IV"), on behalf of MFS Municipal Bond Fund, a segregated portfolio of assets ("series") thereof (the "Acquired Fund"), and MFS Municipal Series Trust, a Massachusetts business trust ("Municipal Trust"), on behalf of MFS Municipal Income Fund, a segregated portfolio of assets ("series") thereof (the "Surviving Fund"), each with its principal place of business at 500 Boylston Street, Boston, Massachusetts 02116. Each of the Acquired Fund and the Surviving Fund are also referred to herein as a "Fund" and, together, as the "Funds." This Agreement is intended to be and is adopted as a plan of reorganization within the meaning of the regulations under Section 368(a) (the "Regulations") of the United States Internal Revenue Code of 1986, as amended (the "Code"). The reorganization will consist of (1) the transfer of the Assets (as defined herein) of the Acquired Fund to the Surviving Fund in exchange solely for the assumption by the Surviving Fund of the Liabilities (as defined herein) of the Acquired Fund and the issuance to the Acquired Fund of shares of beneficial interest, no par value ("shares"), in the Surviving Fund (the "Reorganization Shares"), (2) the distribution of the Reorganization Shares to the shareholders of the Acquired Fund in liquidation of the Acquired Fund as provided herein and (3) the termination of the Acquired Fund, all upon the terms and conditions hereinafter set forth in this Agreement (collectively, the "Reorganization"). All representations, warranties, covenants and obligations of the Surviving Fund and the Acquired Fund contained herein shall be deemed to be representations, warranties, covenants and obligations of Trust IV, acting on behalf of the Acquired Fund, and the Municipal Trust acting on behalf of the Surviving Fund, respectively, and all rights and benefits created hereunder in favor of the Surviving Fund and the Acquired Fund shall inure to, and shall be enforceable by, Trust IV, acting on behalf of the Acquired Fund and the Municipal Trust, acting on behalf of the Surviving Fund, respectively. The Acquired Fund's shares are divided into two classes, designated Class A and Class B shares (the "Class A Acquired Fund Shares," and the "Class B Acquired Fund Shares," respectively, and together, the "Acquired Fund Shares"). The Surviving Fund's shares are divided into five classes, including two classes designated Class A1 and Class B1 shares (the "Class A1 Reorganization Shares" and "Class B1 Reorganization Shares", respectively), which two classes are the only classes of the Surviving Fund's shares involved in the Reorganization and thus included in the term "Reorganization Shares." Each class of Acquired Fund Shares is substantially similar to the corresponding class of Reorganization Shares, i.e., the Acquired Fund's Class A and Class B shares correspond to the Surviving Fund's Class A1 and Class B1 shares. In consideration of the premises of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows: 1. THE REORGANIZATION 1.1 The Acquired Fund will transfer to the Surviving Fund all of its assets (consisting of, without limitation, portfolio securities and instruments, dividend and interest receivables, claims and rights of action, cash and other assets) as set forth in a statement of assets and liabilities as of the Valuation Time (as defined in paragraph 2.1 hereof) prepared in accordance with generally accepted accounting principles consistently applied, certified by the Acquired Fund's Treasurer or Assistant Treasurer and delivered by the Acquired Fund to the Surviving Fund pursuant to paragraph 5.6 hereof (the "Statement of Assets and Liabilities") (collectively, the "Assets"), free and clear of all liens and encumbrances, except as otherwise provided herein, in exchange solely for (a) the assumption by the Surviving Fund of all of the liabilities of the Acquired Fund as set forth in the Statement of Assets and Liabilities (collectively, the "Liabilities") and (b) the issuance and delivery by the Surviving Fund to the Acquired Fund, for distribution in accordance with paragraph 1.3 hereof pro rata to the Acquired Fund shareholders of record determined as of the Valuation Time (the "Acquired Fund Shareholders"), of the number of full and fractional (rounded to the third decimal place) Reorganization Shares determined as provided in paragraph 2.2 hereof. Such transactions shall take place at the closing provided for in paragraph 3.1 hereof (the "Closing"). 1.2 The Acquired Fund has provided the Surviving Fund with a list of the current securities holdings and other assets of the Acquired Fund as of the date of execution of this Agreement. The Acquired Fund reserves the right to sell any of these securities or other assets prior to the Closing. 1.3 On or as soon after the closing date established in paragraph 3.1 hereof (the "Closing Date") as is conveniently practicable (the "Liquidation Date"), the Acquired Fund will distribute the Reorganization Shares it received pursuant to paragraph 1.1 hereof pro rata to the Acquired Fund Shareholders in actual or constructive exchange for their Acquired Fund Shares in complete liquidation of the Acquired Fund. Such distribution will be accomplished by the transfer of the Class A1and Class B1 Reorganization Shares then credited to the account of the Acquired Fund on the books of the Surviving Fund to open accounts on the share records of the Surviving Fund in the names of the Acquired Fund Shareholders and representing the respective pro rata number of full and fractional (rounded to the third decimal place) Class A1 and Class B1 Reorganization Shares due such shareholders, by class (i.e., the account for each Acquired Fund Shareholder of Class A and Class B Acquired Fund Shares shall be credited with the respective pro rata number of Class A1 and Class B1 (as applicable) Reorganization Shares due that shareholder). The Surviving Fund will not issue share certificates representing the Reorganization Shares in connection with such distribution, except in connection with pledges and assignments and in certain other limited circumstances. 1.4 The Acquired Fund shall use reasonable efforts to ensure that Acquired Fund Shareholders holding certificates representing their ownership of Acquired Fund Shares surrender such certificates or deliver an affidavit with respect to lost certificates, in such form and accompanied by such surety bonds as the Acquired Fund may require (collectively, an "Affidavit"), to the Acquired Fund prior to the Closing Date. Any Acquired Fund Share certificate that remains outstanding on the Closing Date shall be deemed to be cancelled, shall no longer show evidence of ownership of Acquired Fund Shares and shall not evidence ownership of any Reorganization Shares. Unless and until any such certificate shall be so surrendered or an Affidavit relating thereto shall be delivered, any dividends and other distributions payable by the Surviving Fund subsequent to the Closing Date with respect to the Reorganization Shares allocable to a holder of such certificate(s) shall be paid to such holder, but such holder may not redeem or transfer such Reorganization Shares. 1.5 Any transfer taxes payable upon issuance of the Reorganization Shares in a name other than the registered holder of the Acquired Fund Shares on the books of the Acquired Fund as of that time shall, as a condition of such issuance and transfer, be paid by the person to whom such Reorganization Shares are to be issued and transferred. 1.6 The legal existence of the Acquired Fund shall be terminated promptly following the Liquidation Date. 2. VALUATION 2.1 The net asset value of each class of the Reorganization Shares and the net value of the Assets shall in each case be determined as of the close of business (4:00 p.m. Boston time) on the Closing Date (the "Valuation Time"). The net asset value of each class of the Reorganization Shares shall be computed by State Street Bank and Trust Company (the "Custodian"), as custodian and pricing agent for the Surviving Fund, using the valuation procedures set forth in Municipal Trust's Amended and Restated Declaration of Trust ("the Municipal Trust's Declaration of Trust") or By-laws and the Surviving Fund's then-current prospectus and statement of additional information (collectively, the "Surviving Fund Valuation Procedures"), to not less than two decimal places. The net value of the Assets shall be computed by the Custodian, as custodian and pricing agent for the Acquired Fund, by calculating the value of the Assets and subtracting therefrom the amount of the Liabilities, using the valuation procedures set forth in Trust IV's Amended and Restated Declaration of Trust ("Trust IV's Declaration of Trust") or By-laws and the Acquired Fund's then-current prospectus and statement of additional information (collectively, the "Acquired Fund Valuation Procedures"). The determinations of the Custodian shall be conclusive and binding on all parties in interest; provided, however, that, in computing each Fund's net asset value in accordance with this paragraph 2.1, any fair value determination required to be made by the Surviving Fund Valuation Procedures or Acquired Fund Valuation Procedures with respect to a portfolio security or other asset of either Fund shall be made in accordance with the applicable Fund's Valuation Procedures, and any such fair value determinations shall be conclusive and binding on the Custodian and all parties in interest. 2.2 The number of each class of Reorganization Shares (including fractional shares, if any, rounded to the third decimal place) the Surviving Fund shall issue pursuant to paragraph 1.1(b) hereof shall be as follows: (a) the number of Class A1 Reorganization Shares shall be determined by dividing the net value of the Assets (computed as set forth in paragraph 2.1 hereof) (the "Acquired Fund Value") attributable to the Class A Acquired Fund Shares by the net asset value of a Class A1 Reorganization Share (computed as set forth in such paragraph), and (b) the number of Class B1 Reorganization Shares shall be determined by dividing the Acquired Fund Value attributable to the Class B Acquired Fund Shares by the net asset value of a Class B1 Reorganization Share (as so computed). 2.3 Except for certain fair value determinations as described in paragraph 2.1 hereof, all computations of value shall be made by the Custodian in its capacity as pricing agent for the Surviving Fund and the Acquired Fund, as applicable, and in accordance with its regular practice in pricing the shares and assets of the Surviving Fund and the Acquired Fund, as applicable, using the relevant Fund's Valuation Procedures. 3. CLOSING AND CLOSING DATE 3.1 The Closing Date shall be March 16, 2007 or such other date on or before June 30, 2007 as the parties may agree. The Closing shall be held at 5:00 p.m., Boston time, at the offices of Trust IV and Municipal Trust, 500 Boylston Street, Boston, Massachusetts 02116, or at such other time and/or place as the parties may agree. 3.2 Portfolio securities shall be transferred by the Acquired Fund to the Custodian for the account of the Surviving Fund on the Closing Date, duly endorsed in proper form for transfer, in such condition as to constitute good delivery thereof in accordance with the custom of brokers or, in the case of portfolio securities held in the US Treasury Department's book-entry system or by the Depository Trust Company or other third-party depositories, by transfer to the account of the Custodian in accordance with Rule 17f-4, Rule 17f-5, or Rule 17f-7, as the case may be, under the Investment Company Act of 1940, as amended (the "1940 Act") and shall be accompanied by all necessary federal and state stock transfer stamps or a check for the appropriate purchase price thereof. The cash delivered shall be in the form of currency, certified or official bank check or federal fund wire, payable to the order of "State Street Bank and Trust Company, Custodian for the MFS Municipal Income Fund" or in the name of any successor organization. 3.3 If on the Closing Date (a) the New York Stock Exchange shall be closed to trading or trading thereon shall be restricted or (b) trading or the reporting of trading on such exchange or elsewhere shall be disrupted so that accurate appraisal of the net value of the Assets or the net asset value of each class of the Reorganization Shares is impracticable, the Closing Date shall be postponed until the next business day when trading shall have been fully resumed and reporting shall have been restored; provided that if trading shall not be fully resumed and reporting restored on or before June 30, 2007, this Agreement may be terminated by either Fund upon the giving of written notice to the other. 3.4 The Acquired Fund shall deliver at the Closing a list of the names, addresses, federal taxpayer identification numbers and backup withholding and nonresident alien withholding status of the Acquired Fund Shareholders and the number of outstanding Acquired Fund Shares owned by each such shareholder, all as of the close of business on the Closing Date (the "Shareholder List"). The Surviving Fund shall issue and deliver to the Acquired Fund a confirmation evidencing the Reorganization Shares credited on the Liquidation Date, or provide evidence satisfactory to the Acquired Fund that such Reorganization Shares have been credited to the Acquired Fund's account on the books of the Surviving Fund. At the Closing each party shall deliver to the other such bills of sale, checks, assignments, stock certificates, receipts or other documents as such other party or its counsel may reasonably request. 4.

Neither Trust IV nor the Acquired Fund know of facts that might form the basis for the institution of such proceedings, and neither Trust IV nor the Acquired Fund is a party to or subject to the provisions of any order, decree or judgment of any court or governmental body that materially and adversely affects their business or their ability to consummate the transactions herein contemplated; (f) The statement of assets and liabilities, including the schedule of portfolio investments, of the Acquired Fund as of August 31, 2006, and the related statement of operations for the fiscal year then ended, and the statement of changes in net assets for the fiscal years ended August 31, 2006 and August 31, 2005 (copies of which have been furnished to the Surviving Fund) have been audited by Deloitte & Touche LLP, Independent Registered Public Accounting Firm, and present fairly in all material respects the financial position of the Acquired Fund as of August 31, 2006 and the results of its operations and changes in net assets for the respective stated periods in accordance with accounting principles generally accepted in the United States of America consistently applied, and there are no known actual or contingent liabilities of the Acquired Fund as of the respective dates thereof not disclosed therein; (g) Since August 31, 2006, there has not been any material adverse change in the Acquired Fund's financial condition, assets, liabilities or business other than changes occurring in the ordinary course of business, or any incurrence by the Acquired Fund of indebtedness maturing more than one year from the date such indebtedness was incurred, except as otherwise disclosed to and accepted by Municipal Trust, on behalf of the Surviving Fund. For the purposes of this subparagraph (g), a decline in net asset value per Acquired Fund Share resulting from losses upon the disposition of investments or from changes in the value of investments held by the Acquired Fund, or a distribution or a payment of dividends shall not constitute a material adverse change; (h) As of the Closing Date, the Acquired Fund will have, within the times and in the manner prescribed by law, properly filed all required federal and other tax returns and reports which, to the knowledge of the Acquired Fund's officers, are required to have been filed by the Acquired Fund by such date and all such returns and reports were complete and accurate in all material respects.

Newton, Associate General Counsel and Senior Vice President of MFS, the Acquired Fund's investment adviser, dated as of the Closing Date, in a form satisfactory to the Surviving Fund to the effect that: (a) Trust IV is a business trust duly organized and validly existing under the laws of The Commonwealth of Massachusetts and has power to own all of its properties and assets and to carry on its business as currently conducted, as described in the Registration Statement. The Acquired Fund is a separate series of Trust IV duly constituted in accordance with Trust IV's Declaration of Trust and By-Laws; (b) this Agreement has been duly authorized, executed and delivered by Trust IV and, assuming that the Surviving Fund prospectus contained in the Registration Statement, the Registration Statement and the Proxy Statement comply with the Acts, and assuming due authorization, execution and delivery of this Agreement by Municipal Trust, on behalf of the Surviving Fund, is a valid and binding obligation of Trust IV and the Acquired Fund enforceable against Trust IV and the Acquired Fund in accordance with its terms, except as the same may be limited by bankruptcy, insolvency, reorganization or other similar laws affecting the enforcement of creditors' rights generally and other equitable principles; (c) Trust IV, on behalf of the Acquired Fund, has power to sell, assign, convey, transfer and deliver the assets contemplated hereby and, upon consummation of the transactions contemplated hereby in accordance with the terms of this Agreement, the Acquired Fund will have duly, sold, assigned, conveyed, transferred and delivered such assets to the Surviving Fund. (d) the execution and delivery of this Agreement did not, and the consummation of the transactions contemplated hereby will not, violate Trust IV's Declaration of Trust or By-Laws, or any material provision of any agreement (known to such counsel) to which Trust IV or the Acquired Fund is a party or by which it is bound or, to the knowledge of such counsel, result in the acceleration of any obligation or the imposition of any penalty, under any agreement, judgment or decree to which Trust IV or the Surviving Fund is a party or by which it is bound; (e) to the knowledge of such counsel, no consent, approval, authorization or order of any court or governmental authority is required for the consummation by Trust IV of the transactions contemplated herein, except such as have been obtained under the Acts and such as may be required under state securities laws; (f) the descriptions in the Proxy Statement of statutes, legal and governmental proceedings and contracts and other documents, if any, only insofar as they relate to Trust IV and the Acquired Fund, are accurate in all material respects; (g) to the knowledge of such counsel, there are no legal or governmental proceedings relating to Trust IV or the Acquired Fund existing on or before the date of mailing the Proxy Statement or the Closing Date required to be described in the Proxy Statement that are not described as required; (h) assuming that consideration therefor of not less than the net asset value and the par value thereof has been paid, and assuming that such shares were issued in accordance with the terms of the Acquired Fund's registration statement or any amendment thereto in effect at the time of such issuance, all issued and outstanding shares of the Acquired Fund are validly issued and outstanding and fully paid and nonassessable (except as described in the Acquired Fund's current prospectus and statement of additional information); (i) to the knowledge of such counsel, Trust IV is a duly registered investment company and, to the knowledge of such counsel, its registration with the Commission as an investment company under the 1940 Act is in full force and effect; and (j) except as may have been previously disclosed by Trust IV on behalf of the Acquired Fund, in writing to Municipal Trust, on behalf of the Surviving Fund, to the knowledge of such counsel, no litigation or administrative proceeding or investigation of or before any court or governmental body is currently pending or threatened as to Trust IV or the Acquired Fund or any of the Acquired Fund's properties or assets, and Trust IV is not a party to or subject to the provisions of any order, decree or judgment of any court or governmental body that materially and adversely affects its business or its ability to consummate the transactions contemplated hereby. Such opinion shall also state that while such counsel has not verified, and is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Proxy Statement, she generally reviewed and discussed certain of such statements with certain officers of Trust IV and that in the course of such review and discussion no facts came to the attention of such counsel that led her to believe that, on the effective date of the Registration Statement or on the date of the Meeting and only insofar as such statements relate to Trust IV or the Acquired Fund, the Proxy Statement contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. Such opinion may state that such counsel does not express any opinion or belief as to the financial statements or other financial or statistical data, or as to the information relating to Municipal Trust or the Surviving Fund, contained in the Proxy Statement or Registration Statement. Such opinion may also state that such opinion is solely for the benefit of Municipal Trust, its Board of Trustees and its officers, and the Surviving Fund. Such opinion shall also include such other matters incidental to the transaction contemplated hereby as the Surviving Fund may reasonably request. 7.5 The assets of the Acquired Fund to be acquired by the Surviving Fund will include no assets which the Surviving Fund, by reason of limitations contained in Municipal Trust's Declaration of Trust or of investment restrictions disclosed in the Surviving Fund's prospectus and statement of additional information in effect on the Closing Date, may not properly acquire. 8. FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF THE MUNICIPAL TRUST ON BEHALF OF THE SURVIVING FUND AND TRUST IV ON BEHALF OF THE ACQUIRED FUND The obligations of Trust IV hereunder are, at the option of Municipal Trust, and the obligations of Municipal Trust hereunder are, at the option of Trust IV , each subject to the further conditions that on or before the Closing Date: 8.1 This Agreement and the transactions contemplated herein shall have been approved by the requisite vote of the holders of outstanding Acquired Fund Shares in accordance with the provisions of Trust IV's Declaration of Trust and By-Laws and the 1940 Act and the rules thereunder, and certified copies of the resolutions evidencing such approval shall have been delivered to the Surviving Fund; 8.2 On the Closing Date no action, suit or other proceeding shall be pending before any court or governmental agency in which it is sought to restrain or prohibit, or obtain damages or other relief in connection with, this Agreement or the transactions contemplated herein; 8.3 All consents of other parties and all other consents, orders and permits of federal, state and local regulatory authorities (including those of the Commission and of state Blue Sky and securities authorities, including "no-action" positions of such federal or state authorities) deemed necessary by Municipal Trust, on behalf of the Surviving Fund, or Trust IV on behalf of the Acquired Fund to permit consummation, in all material respects, of the transactions contemplated hereby shall have been obtained, except where failure to obtain any such consent, order or permit would not involve a risk of a material adverse effect on the assets or properties of either Fund, provided that either Municipal Trust, on behalf of the Surviving Fund, or Trust IV, on behalf of the Acquired Fund may waive any such conditions for itself, respectively; 8.4 The Registration Statement shall have become effective under the 1933 Act and, as of the Closing Date, no stop orders suspending the effectiveness thereof shall have been issued, and, to the best knowledge of the parties hereto, no investigation or proceeding for that purpose shall have been instituted or be pending, threatened or contemplated under the 1933 Act; 8.5 The Acquired Fund shall have declared to Acquired Fund shareholders of record on or prior to the Closing Date a dividend or dividends which together with all previous such dividends shall have the effect of distributing to the Acquired Fund shareholders (a) all of the excess of (i) the Acquired Fund's investment income excludable from gross income under section 103(a) of the Code over (ii) the Acquired Fund's deductions disallowed under sections 265 and 171(a)(2) of the Code, (b) all of the Acquired Fund's investment company taxable income as defined in section 852 of the Code, (computed in each case without regard to any deduction for dividends paid), and (c) all of the Acquired Fund's net realized capital gain (after reduction for any capital loss carryover) in each case for both the taxable year ending on August 31, 2006 and the short taxable year beginning on September 1, 2006 and ending on the Closing Date; 8.6 Trust IV and Municipal Trust shall have received an opinion of Ropes & Gray LLP ("Tax Counsel"), reasonably satisfactory to them, as to the federal income tax consequences mentioned below (the "Tax Opinion"). In rendering the Tax Opinion, Tax Counsel may rely as to factual matters, exclusively and without independent verification, on the representations and warranties made in this Agreement, which Tax Counsel may treat as representations and warranties made to it, and in separate letters addressed to Tax Counsel and certificates delivered pursuant to this Agreement. The Tax Opinion shall be substantially to the effect that, [although not free from doubt], based on the existing provisions of the Code, Treasury regulations, current administrative rules, and court decisions, on the basis of the facts and assumptions stated therein and conditioned on consummation of the Reorganization in accordance with this Agreement, for federal income tax purposes: (a) the Reorganization will constitute a reorganization within the meaning of Section 368(a) of the Code, and Surviving Fund and Acquired Fund each will be a "party to a reorganization" within the meaning of Section 368(b) of the Code; (b) no gain or loss will be recognized by Surviving Fund upon the receipt of the Assets of Acquired Fund in exchange for Reorganization Shares and the assumption by Surviving Fund of the Liabilities of Acquired Fund; (c) the basis in the hands of Surviving Fund of the Assets of Acquired Fund transferred to Surviving Fund in the Transaction will be the same as the basis of such Assets in the hands of Acquired Fund immediately prior to the transfer; (d) the holding periods of the Assets of Acquired Fund in the hands of Surviving Fund will include the periods during which such Assets were held by Acquired Fund; (e) no gain or loss will be recognized by Acquired Fund Shareholders upon the transfer of Acquired Fund's Assets to Surviving Fund in exchange for Reorganization Shares and the assumption by Surviving Fund of the Liabilities of Acquired Fund, or upon the distribution of Reorganization Shares by Acquired Fund to its shareholders in liquidation pursuant to this Agreement; (f) no gain or loss will be recognized by Acquired Fund Shareholders upon the exchange of their Acquired Fund shares for Reorganization Shares; (g) the aggregate basis of Reorganization Shares that an Acquired Fund Shareholder receives in connection with the Reorganization will be the same as the aggregate basis of his or her Acquired Fund shares exchanged therefore; (h) an Acquired Fund Shareholder's holding period for his or her Reorganization Shares will be determined by including the period for which he or she held the Acquired Fund shares exchanged therefore, provided that he or she held such Acquired Fund shares as capital assets; and (i) the Surviving Fund will succeed to and take into account the items of the Acquired Fund described in Section 381(c) of the Code, subject to the conditions and limitations specified in Sections 381, 382, 383 and 384 of the Code and the regulations thereunder. Notwithstanding the above, the Tax Opinion will state that no opinion is expressed as to the effect of the Reorganization on the Funds or any Acquired Fund Shareholder with respect to any Asset as to which any unrealized gain or loss is required to be recognized for federal income tax purposes at the end of a taxable year (or on the termination or transfer thereof) under federal income tax principles. Municipal Trust and Trust IV each agrees to make and provide additional representations to Tax Counsel with respect to the Surviving Fund and the Acquired Fund, respectively, that are reasonably necessary to enable Tax Counsel to deliver the Tax Opinion. Notwithstanding anything herein to the contrary, Municipal Trust and Trust IV may not waive in any material respect the condition set forth in this paragraph 8.6. 8.7 The Board of Trustees of each Fund shall have determined, with respect to each Fund, that the Reorganization is in the best interests of the Fund and is not dilutive of the interests of the Fund's existing shareholders and, based on such determinations, shall have approved this Agreement and the transactions contemplated thereby. 9. BROKERAGE FEES AND EXPENSES; CONTINGENT DEFERRED SALES CHARGES; CERTAIN TAX MATTERS; CERTAIN RECORDS 9.1 Municipal Trust and Trust IV each represents and warrants to the other that there are no brokers or finders entitled to receive any payments from either party to this Agreement in connection with the transactions provided for herein. 9.2 Each Fund will be liable for its own expenses incurred in connection with entering into and carrying out the provisions of this Agreement, whether or not the Reorganization is consummated. 9.3 Reorganization Shares issued in connection with the Reorganization will not be subject to any initial sales charge; however, if any Acquired Fund Shares are at the Closing Date subject to a contingent deferred sales charge (a "CDSC"), the Surviving Fund CDSC schedule and the methodology of aging such shares as set forth in the Surviving Fund Prospectus will apply to the Reorganization Shares issued in respect of such Acquired Fund Shares, and the Reorganization Shares received by Acquired Fund Shareholders pursuant to paragraph 1.4 hereof will, for purposes of calculating the CDSC, if applicable, and determining when the Surviving Fund's Class B1 shares will convert to Class A1 shares of the Surviving Fund, be treated as if purchased on the original date of purchase of such Acquired Fund Shares. 9.4 Trust IV agrees that it or its designee shall, on behalf of the Acquired Fund, file or furnish all federal, state and other tax returns, forms and reports, including information returns and payee statements, if applicable, of the Acquired Fund required by law to be filed or furnished by such dates as required by law to be filed or furnished, and shall provide such other federal and state tax information to shareholders of the Acquired Fund as has been customarily provided by the Acquired Fund, all with respect to the fiscal period commencing September 1, 2006 and ending on the Closing Date. 9.5 Trust IV, on behalf of the Acquired Fund, agrees that it or its designee shall deliver to Municipal Trust, on behalf of the Surviving Fund, on the Closing Date or as soon thereafter as possible: (a) Acquired Fund shareholder statements and tax forms (i.e., Forms 1099) for the taxable years ended August 31, 2005 and August 31, 2006, and the short taxable year commencing on September 1, 2006 and ending on the Closing Date (all on microfilm or microfiche, if available); (b) detailed records indicating the status of all certificates representing ownership of the Acquired Fund Shares issued since inception of the Acquired Fund (e.g., indicating whether the certificates are outstanding or cancelled); and (c) for each Acquired Fund Shareholder, a record indicating the dollar amount of such shareholder's Acquired Fund Share holdings as of such date representing that portion of such holdings subject to a CDSC as of such date and that portion of such holdings not subject to a CDSC as of such date, together with such other information with respect thereto as the Surviving Fund may reasonably request. 10. ENTIRE AGREEMENT Municipal Trust and Trust IV agree that neither party has made any representation, warranty or covenant not set forth herein or referred to in Article 4 hereof or required in connection with paragraph 8.6 hereof and that this Agreement constitutes the entire agreement between the parties. 11. TERMINATION 11.1 This Agreement may be terminated by the mutual agreement of Municipal Trust and Trust IV. In addition, either party may at its option terminate this Agreement unilaterally at or prior to the Closing Date because of: (a) a material breach by the other of any representation, warranty or agreement contained herein to be performed at or prior to the Closing Date; or (b) a condition herein expressed to be precedent to the obligations of the terminating party that has not been met and that reasonably appears will not or cannot be met. 11.2 In the event of any such termination, there shall be no liability for damages on the part of either Municipal Trust or Trust IV, or their respective trustees or officers, to the other party or its trustees or officers, but each shall bear the expenses incurred by it incidental to the preparation and carrying out of this Agreement. 12. AMENDMENTS This Agreement may be amended, modified or supplemented in such manner as may be mutually agreed upon in writing by the authorized officers of Trust IV and Municipal Trust; provided, however, that following the Meeting, no such amendment may have the effect of changing the provisions for determining the number of Reorganization Shares to be issued to the Acquired Fund Shareholders under this Agreement to their detriment without their further approval; and provided further that nothing contained in this Article 12 shall be construed to prohibit the parties from amending this Agreement to change the Closing Date. 13. NOTICES Any notice, report, statement or demand required or permitted by any provisions of this Agreement shall be in writing and shall be personally delivered or given by prepaid telegraph, telecopy or certified mail addressed to Municipal Trust, on behalf of the MFS Municipal Income Fund or Trust IV, on behalf the MFS Municipal Bond Fund (as applicable), 500 Boylston Street, Boston, Massachusetts 02116, Attention: Assistant Secretary. 14.

Trust IV acknowledges that the obligations of or arising out of this instrument are not binding upon any of the Surviving Fund's trustees, officers, employees, agents or shareholders individually, but are binding solely upon the assets and property of the Surviving Fund in accordance with its proportionate interest hereunder. Trust IV further acknowledges that the assets and liabilities of each series of the Surviving Fund are separate and distinct and that the obligations of or arising out of this instrument are binding solely upon the assets or property of the Surviving Fund. 14.6 A copy of Trust IV's Declaration of Trust is on file with the Secretary of State of The Commonwealth of Massachusetts.

The historical statements have been derived from the Municipal Income Fund's and the Municipal Bond Fund's books and records utilized in calculating daily net asset value on September 30, 2006 and for the twelve month period then ended. The pro forma statements give effect to the proposed transfer of all of the assets of the Municipal Bond Fund to the Municipal Income Fund in exchange for the assumption by the Municipal Income Fund of the stated liabilities of the Municipal Bond Fund and for a number of the Municipal Income Fund's shares equal in value to the value of the net assets of the Municipal Bond Fund transferred to the Municipal Income Fund. Under generally accepted accounting principles, the historical cost of investment securities will be carried forward to the surviving entity and the results of operations of the Municipal Income Fund for pre-combination periods will not be restated. The unaudited pro forma combined financial statements should be read in conjunction with the separate financial statements of the Municipal Income Fund and the Municipal Bond Fund incorporated by reference in this Statement of Additional Information.

MFS MUNICIPAL INCOME FUND AND MFS MUNICIPAL BOND FUND NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS (1) BASIS FOR THE COMBINATION The accompanying pro forma financial statements are presented to show the effect of the proposed reorganization of MFS Municipal Bond Fund (Municipal Bond Fund) into MFS Municipal Income Fund (Municipal Income Fund), (The Municipal Bond Fund and Municipal Income Fund are referred to herein as the "Funds"), as if such reorganization had taken place as of September 30, 2006, the semi annual period of the Municipal Income Fund. The following notes refer to the accompanying pro forma financial statements as if the reorganization of the Municipal Bond Fund with and into the Municipal Income Fund had taken place as of September 30, 2006 at the respective net asset value on that date. Municipal Income Fund will be the accounting survivor, based upon an analysis of factors including surviving fund portfolio manager, investment objectives and policies, expense ratio structures and portfolio composition and size. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, the security could decline in value, interest from the security could become taxable and the fund may be required to issue Forms 1099-DIV. INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as reported by an independent pricing service. Values of debt instruments obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Swaps are generally valued at a broker-dealer bid quotation. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund's investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the fund's valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments. These investments are generally valued at fair value based on information from independent pricing services. The adviser may rely on independent pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the fund's net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the fund's net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the fund uses derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include swap agreements. SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an exchange of cash payments between the fund and another party. Net cash payments are exchanged at specified intervals and are recorded as a realized gain or loss in the Statement of Operations. The value of the swap is adjusted daily and the change in value, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements involve the periodic exchange of cash flows, such as the exchange of fixed rate interest payments for floating rate interest payments based on a notional principal amount. The interest rates may be based on a specific financial index or the exchange of two distinct floating rate payments. The fund may enter into an interest rate swap in order to manage its exposure to interest and foreign exchange fluctuations. (3) SHARES OF BENEFICIAL INTEREST The pro forma combined shares of beneficial interest outstanding represent those shares that would have been outstanding on September 30, 2006, had the acquisition taken place on September 30, 2006. In exchange for the net assets of the Municipal Bond Fund each class of shares of the Municipal Income Fund would have been issued based upon the per share net asset value as follows: ------------------------------------------------------------------------------- CLASS A1 CLASS B1 ------------------------------------------------------------------------------- Net assets - Municipal Bond Fund $1,024,624,262 $42,245,966 ------------------------------------------------------------------------------- Shares - Municipal Income Fund 119,142,356 4,906,616 ------------------------------------------------------------------------------- Net asset value - Municipal Income Fund $8.60 $8.61 ------------------------------------------------------------------------------- (4) ADJUSTMENTS TO THE PRO FORMA COMBINED STATEMENTS The pro forma combined statements assume similar rates of gross investment income for the Municipal Bond Fund and Municipal Income Fund investments. Accordingly, the combined gross investment income is equal to the sum of each of the fund's gross investment income. Certain expenses have been adjusted to reflect the expected expenses of the combined entity. The pro forma investment advisory, administration, custody, and distribution fees of the combined fund are based on the fee schedule in effect for the Municipal Income Fund at the combined level of the average net assets for the twelve months ended September 30, 2006. (A) Expenditures are reduced as a result of the elimination of duplicative functions. (B) The management fee is computed daily and paid monthly at an annual rate of 0.55% of the MFS Municipal Income Fund's average daily net assets. For MFS Municipal Bond Fund the management fee is computed daily and paid monthly at the following annual rates: First $1.3 billion of average daily net assets 0.40% Next $0.7 billion of average daily net assets 0.37% Average daily net assets in excess of $2 billion 0.35% As part of a settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the management fee to 0.30% of each fund's average daily net assets for the period March 1, 2004 through February 28, 2009. (C) Administrator - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The post merger tiered rate will be as follows: $0 - $50 million 0.00000% $50 - $750 million 0.01750% $750 million - $1.5 billion 0.01700% $1.5 - $2.5 billion 0.01650% $2.5 - $4 billion 0.01200% > $4 billion 0.00000% The fund is charged a fixed amount plus a fee based on calendar year average net assets. Effective April 1, 2006, the fund's annual fixed amount is $17,500. (5) TAX MATTERS AND DISTRIBUTIONS Each fund's policy is to comply with the provision of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Under the terms of the Agreement and Plan of Reorganization, the reorganization of the Municipal Bond Fund and the Municipal Income Fund should be treated as a tax-free business combination. The yearly utilization of any capital loss acquired by the Municipal Income Fund is limited by the Internal Revenue Code.

In onnection with this opinion, I have examined the following documents: (a) the Registration Statement; (b) the Agreement and Plan; (c) a certificate of the Secretary of State of The Commonwealth of Massachusetts as to the existence of the Trust; (d) copies of the Trust's Amended and Restated Declaration of Trust ("Declaration of Trust") and of all amendments thereto on file in the office of the Secretary of State; and (e) the Trust's Amended and Restated By-Laws and certain votes of the Trustees of the Trust. In such examination, I have assumed the genuineness of all signatures, the conformity to the originals of all of the documents reviewed by me as copies, the authenticity and completeness of all original documents reviewed by me in original or copy form and the legal competence of each individual executing any document. I have also assumed, for the purposes of this opinion, that the Agreement and Plan, in substantially the form reviewed by me, is duly delivered by the parties thereto and that all of the conditions set forth in "Information About the Reorganization" in the Registration Statement shall have occurred prior to the issuance and sale of the Shares. This opinion is based entirely on my review of the documents listed above. I have made no other review or investigation of any kind whatsoever, and I have assumed, without independent inquiry, the accuracy of the information set forth in such documents. This opinion is limited solely to the laws of The Commonwealth of Massachusetts (other than the Massachusetts Uniform Securities Act, as to which I express no opinion) as applied by courts in such Commonwealth. I understand that all of the foregoing assumptions and limitations are acceptable to you. Based upon and subject to the foregoing, please be advised that it is my opinion that the Shares, when issued and sold in accordance with the Registration Statement, the Agreement and Plan and the Trust's Declaration of Trust and By-laws, will be legally issued, fully paid and non-assessable, except that shareholders of the Trust may under certain circumstances be held personally liable for the Trust's obligations. A copy of the Trust's Declaration of Trust is on file with the Secretary of State of the Commonwealth of Massachusetts. I note specifically that the obligations of or arising out of the Agreement and Plan are not binding upon any of the Trust's trustees, officers, employees, agents or shareholders individually, but are binding solely upon the assets and property of the Trust in accordance with its interest under the Agreement and Plan. I further note that the assets and liabilities of each series of the Trust, such as the Municipal Income Fund, are separate and distinct and that the Municipal Income Fund's obligations of or arising out of the Agreement and Plan are binding solely upon the assets or property of the Municipal Income Fund I hereby consent to the filing of this opinion as an exhibit to the Registration Statement.

No filing fee is required pursuant to General Instruction B of Form N-14. The purpose of this Form N-14 is to effect a reorganization of MFS Municipal Bond Fund, ("Municipal Bond Fund"), a series of MFS Series Trust IV, with MFS Municipal Income Fund ("Municipal Income Fund"), a series of MFS Municipal Series Trust, pursuant to which Municipal Income Fund will acquire all of the assets and liabilities of the Municipal Bond Fund (the "Reorganization"). The Registration Statement includes a shareholder letter, notice of meeting, combined Prospectus/Proxy Statement, and forms of voting instructions card and proxy which are proposed to be used by the Municipal Bond Fund in connection with the Municipal Bond Fund's Special Meeting of Shareholders to be held on March 7, 2007. It is intended that definitive proxy materials be mailed to shareholders of the Municipal Bond Fund on or around January 24, 2007. Class A and Class B shareholders of Municipal Bond Fund would receive Class A1 and Class B1 shares of Municipal Income Fund, respectively, which are being established in connection with the Reorganization. A related post-effective amendment was filed by MFS Municipal Series Trust, on behalf of Municipal Income Fund, on November 16, 2006 to establish Class A1 and Class B1 shares.
