These procedures are described detail below. - --------------------------------------------------------------------------------------------------------- Comparison of Risks Since each fund primarily invests in Municipal Securities, the two funds have similar risk characteristics. These risks are discussed in the Risk/Return Summary under "Principal risks of investing in the funds." Because Tax-Free Income Fund can invest in Municipal Securities with longer maturities, it is more susceptible than Intermediate Tax-Free Fund to changes in interest rates. However, Intermediate Tax-Free Fund can invest in lower rated securities, which entail greater risk of default. Reorganization o The reorganization is scheduled to occur as of 5:00 p.m., Eastern time, on March 31, 1999, but may occur as of any later date before September 30, 1999. Your fund will transfer all of its assets to Tax-Free Income Fund. Tax-Free Income Fund will assume your fund's liabilities. The net asset values of both funds will be computed as of the close of the New York Stock Exchange (normally 4:00 p.m. Eastern time) on the reorganization date. o Tax-Free Income Fund will issue to your fund Class A shares of Tax-Free Income Fund in an amount equal to the aggregate net asset value of your fund's Class A shares. Your fund will immediately distribute these shares to your fund's Class A shareholders in proportion to their holdings on the reorganization date. In this same manner, Tax-Free Income Fund will issue to your fund Class B and Class C shares that will be distributed to your fund's Class B and Class C shareholders in proportion to their respective holdings on the reorganization date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Tax-Free Income Fund, Class B shareholders of your fund will end up as Class B shareholders of Tax-Free Income Fund, and Class C shareholders of your fund will end up as Class C shareholders of Tax-Free Income Fund. o After the reorganization is over, your fund will be terminated. 4 o The reorganization will be federally tax-free and will not take place unless both funds receive a satisfactory opinion concerning the federal income tax consequences of the reorganization from Hale and Dorr LLP, counsel to the funds. Other Consequences of the Reorganization. Each fund pays monthly advisory fees equal to the following annual percentage of average daily net assets: - -------------------------------------------------------------------------------- Fund Asset Breakpoints Intermediate Tax-Free Tax-Free Income - -------------------------------------------------------------------------------- First $250 million 0.50% - ------------------------------------- ---------------- Over $250 million up to $300 million 0.50% 0.48% - ------------------------------------- ---------------- Over $300 million 0.45% - -------------------------------------------------------------------------------- Thus, at all asset levels, the annual advisory fee rate payable by Tax-Free Income Fund is the same as or lower than the rate paid by your fund. Because of Tax-Free Income Fund's current asset size, which at December 31, 1998 exceeded $300 million, your fund's advisory fee rate (without giving effect to fee waivers) is higher than the fee rate payable by Tax-Free Income Fund. Your fund is currently paying a lower advisory fee because of voluntary fee waivers. These fee waivers may be discontinued by Pioneer at any time. In addition to lower advisory fee rates, Tax-Free Income Fund's Class A expense ratio of 0.93% for the calendar year ended December 31, 1997, as well as its pro forma expense ratio of 0.95%, are lower than your fund's gross Class A expense ratio of 1.18% (1.00% for net expenses with the expense limitation). Furthermore, Tax-Free Income Fund's other expenses are lower than your fund's gross other expenses. Both funds pay the same 12b-1 fee rates for each class. Although Pioneer has voluntarily agreed to limit your fund's expenses, your fund's total annual operating expenses are still higher than Tax-Free Income Fund's. In light of your fund's inability to attract significant assets, Pioneer may not continue to subsidize a portion of your fund's expenses indefinitely. If Pioneer discontinued this voluntary limitation, your fund's total annual operating expenses would rise even further above Tax-Free Income Fund's. RISK/RETURN SUMMARY Investment objectives Intermediate Tax-Free Fund. As high a level of current income exempt from federal income taxes from a high-quality portfolio of municipal bonds as is consistent with prudent investment risk. Tax-Free Income Fund. As high a level of current income exempt from federal income taxes as possible consistent with the preservation of capital. Investment strategies Intermediate Tax-Free Fund. Intermediate Tax-Free Fund invests at least 80% of its assets in bonds, notes and other debt instruments issued by or on behalf of states, territories or possessions of the U.S. and the District of Columbia and their political subdivisions, agencies or instrumentalities, the interest on which is exempt from federal income tax ("Municipal Securities"). The municipal bonds in which the fund invests are rated in the three highest rating categories by a nationally recognized statistical rating organization or determined by Pioneer to be of comparable quality; provided that up to 15% of the fund's assets may be rated BBB. The municipal notes in which the fund may invest are rated AAA, AA or A by a nationally recognized statistical rating organization or determined by Pioneer to be of comparable quality. No more than 15% of the fund's assets may be rated BBB. The dollar weighted average maturity of the fund's portfolio will not exceed 10 years. At least 80% of the fund's assets have a remaining maturity of 15 years or less. Tax-Free Income Fund. Tax-Free Income Fund invests in a diversified portfolio of Municipal Securities rated in the three highest rating categories by Moody's Investors Service, Inc. or Standard & Poor's Ratings Group. The Municipal Securities in which the fund invests may be of any maturity and the fund has no policy with respect to the average maturity of its portfolio. Pioneer, each fund's investment adviser, considers both macroeconomic and issuer specific factors in selecting a portfolio designed to achieve each fund's investment objective. In assessing the appropriate maturity, rating and sector weighing of a fund's portfolio, Pioneer considers a variety of macroeconomic factors that are expected to influence economic activity and interest rates. These factors include fundamental economic indicators, Federal Reserve monetary policy and the relative value of the U.S. dollar compared to other currencies. Once Pioneer determines the preferable portfolio characteristics, Pioneer selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issuers), liquidity and rating, and sector and issuer diversification. Pioneer also employs fundamental research and due diligence to assess an issuer's credit quality, taking into account financial condition, future capital needs, and potential for change in rating. In making these portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its own staff who have access to a wide variety of research. 5 Principal risks of investing in the funds Each fund is subject to similar risks. Even though each fund seeks current income, you could lose money on your investment or not make as much as if you invested elsewhere if: o Interest rates increase, causing the value of a fund's portfolio to decline o The issuer of a security owned by a fund defaults on its obligation to pay principal or interest or has its credit rating downgraded o New federal or state legislation adversely affects the tax-exempt status of securities held by a fund or the financial ability of municipalities to repay these obligations o The issuer of a Municipal Security may not be able to make timely payments because of a general economic downturn or increased governmental costs o Pioneer is incorrect in its expectation of changes in interest rates or the credit quality of an issuer It is possible that some of a fund's income distributions may be, and distributions of a fund's capital gains will be, subject to federal taxation. A fund may realize taxable gains on the sale of its securities or other transactions, and some of a fund's income distributions may be subject to the federal alternative minimum tax. In addition, distribution of a fund's income and gains generally will be subject to state taxation. 6 Each fund's past performance The bar chart and table indicate the risks of investing in the fund by showing how the funds have performed in the past. Each fund's performance varies from year to year. A fund's past performance does not necessarily indicate how it will perform in the future. As a shareholder, you may lose or make money on your investment. Intermediate Tax-Free Fund's highest calendar quarterly return was 6.12% (12/31/94 to 3/31/95); Tax-Free Income Fund's highest calendar quarterly return was 7.11% (12/31/94 to 3/31/95) Intermediate Tax-Free Fund's lowest calendar quarterly return was -5.06% (12/31/93 to 3/31/94); Tax-Free Income Fund's lowest calendar quarterly return was -5.87% (12/31/93 to 3/31/94) Annual return Class A shares (Year ended December 31) Intermediate Tax-Free Fund Tax-Free Income Fund '89 9.77% 10.12% '90 6.42% 7.40% '91 11.17% 12.49% '92 8.65% 8.73% '93 11.08% 12.98% '94 -6.02% -6.38% '95 13.80% 16.83% '96 3.03% 3.57% '97 6.87% 8.94% '98 5.28% 6.20% Comparative performance The table shows the average annual total returns of each class of the funds and compares these returns to the returns of the Lehman Brothers Municipal Bond Index, an unmanaged index of municipal bonds.

This section describes additional investments that a fund may make or strategies that it may pursue to a lesser degree to achieve the fund's goal. Some of the funds' secondary investment policies also entail risks. To learn more about these investments and risks, you should obtain and read the statement of additional information (SAI). Temporary investments Normally, each fund invests substantially all of its assets to meet its investment objective. Each fund may invest the remainder of its assets in securities with a remaining maturity of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, each fund may depart from its principal investment strategies and invest part or all of its assets in these securities. During such periods, the fund may not be able to achieve its investment objective. The funds intend to adopt a defensive strategy only when Pioneer believes Municipal Securities have extraordinary risks due to political or economic factors. Short-term trading The funds usually do not trade for short-term profits. Each fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If a fund does a lot of trading, it may incur additional operating expenses, which would reduce performance and could cause shareholders to receive larger distributions of taxable income or capital gains. Derivatives Each fund may use futures, options and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Each fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, a fund may use derivatives for a variety of purposes, including: o As a hedge against adverse changes in interest rates o As a substitute for purchasing or selling securities o To increase the fund's return Even a small investment in derivatives can have a significant impact on a fund's exposure to interest rates. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments, the fund may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. Year 2000 Information technology experts are concerned about computer and other electronic systems' ability to process date related information on and after January 1, 2000. This scenario, commonly referred to as the "Year 2000 problem," could have an adverse impact on the funds and the provision of services to their shareholders. Pioneer is addressing the Year 2000 problem with respect to its systems and those used by the distributor and transfer agent. During 1999, Pioneer expects to finish addressing all material Year 2000 issues and to participate in industry-wide testing. The funds have obtained assurances from their other service providers that they are taking appropriate Year 2000 measures and Pioneer is monitoring their efforts. Although neither fund expects the Year 2000 problem to adversely impact it, neither fund can guarantee that its, or the fund's service providers', efforts will be successful. PROPOSAL 1 APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION Description of Reorganization The shareholders of your fund are being asked to approve an Agreement and Plan of Reorganization, a copy of which is attached as Exhibit A. The Agreement provides for a reorganization on the following terms: o The reorganization is scheduled to occur as of 5:00 p.m., Eastern time, on March 31, 1999, but may occur on any later date before September 1, 1999. Your fund will transfer all of its assets to Tax-Free Income Fund, and Tax-Free Income Fund will assume all of your fund's liabilities. This will result in the addition of your fund's assets to Tax-Free Income Fund's portfolio. The net asset values of both funds will be computed as of the close of the New York Stock Exchange (normally 4:00 p.m. Eastern time) on the reorganization date. 10 o Tax-Free Income Fund will issue to your fund Class A shares of Tax-Free Income Fund in an amount equal to the aggregate net asset value of your fund's Class A shares. As part of the liquidation of your fund, your fund will immediately distribute these shares to Class A shareholders of record of your fund in proportion to their holdings on the reorganization date. In this same manner, Tax-Free Income Fund will issue to your fund Class B and Class C shares that will be distributed to your fund's Class B and Class C shareholders in proportion to their respective holdings on the reorganization date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Tax-Free Income Fund, Class B shareholders of your fund will end up as Class B shareholders of Tax-Free Income Fund, and Class C shareholders of your fund will end up as Class C shareholders of Tax-Free Income Fund. o After the reorganization is over, your fund will be terminated. Reasons for the Proposed Reorganization The board of trustees of your fund believes that the proposed reorganization will be advantageous to the shareholders of your fund for several reasons. The board of trustees considered the following matters, among others, in approving the proposal. First, that a combined fund offers economies of scale that may lead to better control over expenses than is possible for your fund. Both funds incur substantial costs for accounting, legal, transfer agency, insurance, and custodial and administrative services. Second, that shareholders may be better served by a less restrictive fund. Your fund has a policy of concentrating its investments in municipal bonds with a dollar-weighted average maturity not exceeding 10 years. This has limited the fund's ability to purchase higher yielding bonds with longer maturities and has limited the fund's ability to gather assets. Tax-Free Income Fund has no stated policy with respect to maturity, allowing it to invest in a broader range of securities, and it has a significantly larger asset size than your fund. Third, that Tax-Free Income Fund has performed better than your fund since its inception. While past performance cannot predict future results, the trustees believe that Tax-Free Income Fund is better positioned than your fund to continue to generate strong returns because of its lower expense ratio and more flexible investment policies. Fourth, that Tax-Free Income Fund's expenses are currently lower than your fund's expenses. Additionally, if the voluntary limitation on your fund's expenses were discontinued, your fund's expenses would be substantially higher. Shareholders of your fund would pay relatively lower fees each month as shareholders of Tax-Free Income Fund than they would if the reorganization did not occur, and even less if the voluntary expense limitation on your fund's expenses were discontinued. Fifth, that Tax-Free Income Fund is more widely recognized in the broker community as Pioneer's primary municipal bond fund. By offering both funds simultaneously, it has been increasingly difficult to attract assets to your fund. Sixth, that the Tax-Free Income Fund shares received in the reorganization will provide your fund's shareholders with substantially the same investment advantages as they currently have, with potential for higher return. The board of trustees of Tax-Free Income Fund considered that the reorganization presents an excellent opportunity for Tax-Free Income Fund to acquire investment assets without the obligation to pay commissions or other transaction costs that are normally associated with the purchase of securities. The trustees also believe that your fund's shareholders and Tax-Free Income Fund's shareholders will benefit from improved diversification as a result of the reorganization. Because Tax-Free Income Fund is a significantly larger fund than your fund and because it does not place restrictions on portfolio maturity, the trustees feel that the addition of your fund's assets will improve the diversification of Tax-Free Income Fund's overall portfolio. This opportunity provides an economic benefit to Tax-Free Income Fund and its shareholders. Similarly, the trustees feel that shareholders of your fund will benefit from the greater diversification of Tax-Free Income Fund's investment portfolio after the transaction. The boards of trustees of both funds also considered that the adviser and the funds' distributor will also benefit from the reorganization. For example, the adviser might realize time savings from a consolidated portfolio management effort and from the need to prepare fewer reports and regulatory filings as well as prospectus disclosure for one fund instead of two. The trustees believe, however, that these savings will not amount to a significant economic benefit. Because of the fee waiver on your fund, Pioneer will also receive a higher effective fee from managing the assets attributable to your fund if they are a part of Tax-Free Income Fund than if the reorganization does not take place. Comparative Fees and Expense Ratios. As discussed above in the Summary, Tax-Free Income Fund pays the same advisory fee rate as your fund for assets up to $250 million, and pays a rate lower than your fund's fee rate at all other asset levels. In addition, because your fund's advisory fee does not have breakpoints, the management fee will remain the same indefinitely. In addition to lower advisory fee rates, Tax-Free Income Fund's Class A expense ratio of 0.93% for the calendar year ended December 31, 1997, as well as its pro forma expense ratio of 0.95%, are lower than your fund's gross Class A expense ratio of 1.18% (1.00% for net expenses with the expense limitation). Furthermore, Tax-Free Income Fund's other expenses are lower than your fund's gross other expenses. Both funds pay the same 12b-1 fee rates for each class. 11 The trustees do not believe, given your fund's current size and growth rate, that your fund will grow to an asset size which would allow your fund to realize the benefits of economies of scale, including better control over expenses. The trustees also do not believe that your fund will reach an asset size which will allow your fund to significantly improve the diversification of its investment portfolio. In light of your fund's inability to attract significant assets, the adviser may not continue to subsidize a portion of your fund's expenses indefinitely. When the adviser discontinues this voluntary limitation, your fund's expense ratio will rise even higher above Tax-Free Income Fund's. Comparative Performance. The trustees also took into consideration the relative performance of your fund and Tax-Free Income Fund. As shown in the table in the Risk/Return Summary, Tax-Free Income Fund has had better performance than your fund over time. Unreimbursed Class A Distribution and Shareholder Service Expenses The boards of trustees of your fund and Tax-Free Income Fund have determined that, if the reorganization occurs, unreimbursed distribution and shareholder service expenses incurred under your fund's Class A 12b-1 Plan will be reimbursable expenses under Tax-Free Income Fund's Class A Rule 12b-1 Plan. However, the maximum aggregate amount payable annually under Tax-Free Income Fund's Class A 12b-1 Plan (0.25% of average daily net assets attributable to Class A shares) will not increase. The 12b-1 Plans for Class B and C are compensation plans and, consequently, the amounts payable under such plans are not determined by references to actual distribution expenses incurred. The following table shows the actual and pro forma unreimbursed distribution and shareholder service expenses of Class A shares of your fund and Tax-Free Income Fund. The table shows both the dollar amount of these expenses and the percentage of each class' net assets on December 31, 1998 that they represent. - ------------------------------------------------------------------------------------------------ Intermediate Tax-Free Tax-Free Income Unreimbursed Class A 12b-1 Expenses Class A shares Class A shares - ------------------------------------------------------------------------------------------------ $56,915 Actual expenses as of December 31, 1998 $0 less than 0.01% - ------------------------------------------------------------------------------------------------ $56,915 Pro forma combined expenses as of January 1, 1998 -- less than 0.01% - ------------------------------------------------------------------------------------------------ The Class A Plan does not provide for the carryover of reimbursable expenses beyond 12 months from the time a fund is first invoiced for an expense. The limited carryover provision in the Class A Plan may result in an expense invoiced to a fund in one fiscal year being paid in the subsequent fiscal year and thus being treated for purposes of calculating the maximum expenditures of the fund as having been incurred in the subsequent fiscal year. In the event of termination or non-continuance of the Class A Plan, a fund has 12 months to reimburse any expense which it incurs prior to such termination or non-continuance, provided that payments by the fund during such 12-month period shall not exceed 0.25% of the fund's average daily net assets during such period. Tax Status of the Reorganization The reorganization will be tax-free for federal income tax purposes and will not take place unless both funds receive a satisfactory opinion from Hale and Dorr LLP, counsel to the funds, substantially to the effect that: o The reorganization described above will be a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and each fund will be "a party to a reorganization" within the meaning of Section 368(b) of the Code; o No gain or loss will be recognized by your fund upon (1) the transfer of all of its assets to Tax-Free Income Fund as described above or (2) the distribution by your fund of Tax-Free Income Fund shares to your fund's shareholders; o No gain or loss will be recognized by Tax-Free Income Fund upon the receipt of your fund's assets solely in exchange for the issuance of Tax-Free Income Fund shares to your fund and the assumption of all of your fund's liabilities by Tax-Free Income Fund; o The basis of the assets of your fund acquired by Tax-Free Income Fund will be the same as the basis of those assets in your fund immediately before the transfer; o The tax holding period of the assets of your fund in Tax-Free Income Fund will include your fund's tax holding period for those assets; o The shareholders of your fund will not recognize gain or loss upon the exchange of all their shares of your fund solely for Tax-Free Income Fund shares as part of the reorganization; o The basis of Tax-Free Income Fund shares received by your fund's shareholders in the reorganization will be the same as the basis of the shares of your fund surrendered in exchange; and 12 o The tax holding period of the Tax-Free Income Fund shares received by your fund's shareholders will include, for each shareholder, the tax holding period of the shares of your fund surrendered in exchange, provided that shares of your fund were held as capital assets on the date of the exchange. Additional Terms of Agreement and Plan of Reorganization Surrender of Share Certificates. Shareholders of your fund whose shares are represented by one or more share certificates need not surrender their certificates. After the reorganization, certificates evidencing ownership of your fund's shares will evidence ownership of Tax-Free Income Fund shares received in the reorganization. Shareholders must continue to follow procedures for surrendering share certificates (or delivering the appropriate affidavit) in order to redeem shares of Tax-Free Income Fund after the reorganization. Tax-Free Income Fund will not issue share certificates in the reorganization. Conditions to Closing the Reorganization. The obligation of your fund to consummate the reorganization is subject to the satisfaction of certain conditions, including the performance by Tax-Free Income Fund of all its obligations under the Agreement and the receipt of all consents, orders and permits necessary to consummate the reorganization (see Agreement, sections 6 and 8). The obligation of Tax-Free Income Fund to consummate the reorganization is subject to the satisfaction of certain conditions, including your fund's performance of all of its obligations under the Agreement, the receipt of certain documents and financial statements from your fund and the receipt of all consents, orders and permits necessary to consummate the reorganization (see Agreement, sections 7 and 8). The obligations of both funds are subject to the approval of the Agreement by the necessary vote of the outstanding shares of your fund, in accordance with the provisions of your fund's declaration of trust and by-laws. The funds' obligations are also subject to the receipt of a favorable opinion of Hale and Dorr LLP as to the federal income tax consequences of the reorganization (see Agreement, paragraph 8.7). Termination of Agreement. The board of trustees of either your fund or Tax-Free Income Fund may terminate the Agreement (even if the shareholders of your fund have approved it) at any time before the reorganization date, if that board believes that proceeding with the reorganization would no longer be advisable. Expenses of the Reorganization. Tax-Free Income Fund and your fund will each be responsible for its own expenses incurred in connection with entering into and carrying out the provisions of the Agreement, whether or not the reorganization occurs. These expenses are estimated to be approximately $40,000, which will be allocated to the funds on the basis of their relative net assets. CAPITALIZATION The following table sets forth the capitalization of each fund as of December 31, 1998, and the pro forma combined capitalization of both funds as if the reorganization had occurred on such date. The table reflects pro forma exchange ratios of approximately 0.8603 Class A Tax-Free Income Fund shares being issued for each Class A share of your fund, approximately 0.8724 Class B Tax-Free Income Fund shares being issued for each Class B share of your fund and approximately 0.8665 Class C Tax-Free Income Fund shares being issued for each Class C share of your fund. If the reorganization occurs, the actual exchange ratios on the reorganization date will vary due to changes in the market value of the portfolio securities of both Tax-Free Income Fund and your fund between December 31, 1998 and the reorganization date, changes in the amount of undistributed net investment income and net realized capital gains of Tax-Free Income Fund and your fund during that period resulting from income and distributions, and changes in the accrued liabilities of Tax-Free Income Fund and your fund during the same period. December 31, 1998 Intermediate Tax-Free Tax Free Income Tax-Free Income Pro Forma -------- ------ --------- Net Assets .............. $62,058,674 $407,442,319 $469,500,993 Net Asset Value Per Share Class A ................ $ 10.35 $ 12.02 $ 12.02 Class B ................ $ 10.39 $ 11.93 $ 11.93 Class C ................ $ 10.34 $ 11.94 $ 11.94 Shares Outstanding Class A ................ 5,561,494 32,730,448 37,514,855 Class B ................ 351,026 904,102 1,210,327 Class C ................ 84,260 273,127 346,137 It is impossible to predict how many Class A, Class B and Class C shares of Tax-Free Income Fund will actually be received and distributed by your fund on the reorganization date. The table should not be relied upon to determine the number or value of Tax-Free Income Fund shares that will actually be received and distributed. 13 COMPARISON OF BUSINESS TRUSTS UNDER DELAWARE AND MASSACHUSETTS LAW Your fund is organized as a Massachusetts business trust. Tax-Free Income Fund is organized as a Delaware business trust. The following is a comparison of the laws of Massachusetts and Delaware applicable to business trusts. Limitation of Shareholders' and Funds' Liability. Delaware law provides that the shareholders of a Delaware business trust shall not be subject to liability for the debts or obligations of the trust. Under Massachusetts law, shareholders of a Massachusetts business trust (such as your fund) may, under certain circumstances, be liable for the debts and obligations of that trust. Although the risk of liability of shareholders of a Massachusetts business trust who do not participate in the management of the trust may be remote, your board of trustees has determined that Delaware law affords greater protection against potential shareholder liability. Similarly, Delaware law provides that, to the extent that a Delaware business trust issues multiple series of shares, each series shall not be liable for the debts or obligations of any other series, another potential, although remote, risk in the case of multiple series of a Massachusetts business trust. While your board of trustees believes that a Massachusetts business trust will only be liable for its own obligations, there is no direct statutory or judicial support for that position. Limitation of Trustee Liability. Delaware law provides that, except to the extent otherwise provided in a trust's declaration of trust or by-laws, trustees will not be personally liable to any person (other than the business trust or a shareholder thereof) for any act, omission or obligation of the business trust or any trustee thereof. Delaware law also provides that a trustee's actions under a Delaware business trust's declaration of trust or by-laws will not subject the trustee to liability to the business trust or its shareholders if the trustee takes such action in good faith reliance on the provisions of the business trust's declaration of trust or by-laws. The declaration of trust of a Massachusetts business trust may limit the liability of a trustee who is not also an officer of the trust for breach of fiduciary duty except for, among other things, any act or omission not in good faith which involves intentional misconduct or a knowing violation of law or any transaction from which such trustee derives an improper direct or indirect financial benefit. The limitations on trustee liability under Delaware law are equivalent to the protections for liability provided to directors of a corporation under Delaware law. These limitations will be beneficial in attracting and retaining in future qualified persons to act as trustees. Shareholder Voting. Delaware law provides that a Delaware business trust's declaration of trust or by-laws may set forth provisions related to voting in any manner. This provision appears to permit trustee and shareholder voting through computer or electronic media. For an investment company with a significant number of institutional shareholders, all with access to computer or electronic networks, the use of such voting methods could significantly reduce the costs of shareholder voting. However, the advantage of such methods may not be realizable unless the SEC modifies its proxy rules. Also, as required by the Investment Company Act of 1940 (the "1940 Act"), votes on certain matters by trustees would still need to be taken at in-person meetings. Declarations of Trust. Although neither a Delaware business trust nor a Massachusetts business trust is required to hold annual shareholder meetings, Delaware law affords to the trustees the ability to adapt the Delaware business trust to future contingencies without the necessity of holding a special shareholder meeting. The trustees of a Delaware business trust may have the power to amend the business trust's governing instrument to create a class or series of shares of beneficial interest that was not previously outstanding; to dissolve the business trust; to incorporate the Delaware business trust; to merge or consolidate with another entity; to sell, lease, exchange, transfer, pledge or otherwise dispose of all or any part of the business trust's assets; to cause any series to become a separate trust; and to change the Delaware business trust's domicile--all without shareholder vote. Any exercise of authority by the trustees will be subject to applicable state and federal law. The flexibility of Delaware business trusts should help to assure that a Delaware business trust always operates under the most advantageous form of organization and is intended to reduce the expense and frequency of future shareholder meetings for non-investment-related operational issues. BOARDS' EVALUATION AND RECOMMENDATION For the reasons described above, the board of trustees of your fund, including the trustees who are not "interested persons" of your fund or the adviser (the independent trustees), approved the reorganization. In particular, the trustees determined that the reorganization was in the best interests of your fund and that the interests of your fund's shareholders would not be diluted as a result of the reorganization. Similarly, the board of trustees of Tax-Free Income Fund, including the independent trustees, approved the reorganization. They also determined that the reorganization was in the best interests of Tax-Free Income Fund and that the interests of Tax-Free Income Fund's shareholders would not be diluted as a result of the reorganization. The trustees of your fund recommend that you vote FOR the proposal to approve the Agreement and Plan of Reorganization. VOTING RIGHTS AND REQUIRED VOTE Each share of your fund is entitled to one vote. Approval of the above proposal requires the affirmative vote of a majority of the shares of your fund outstanding and entitled to vote. For this purpose, a majority of the outstanding shares of your fund means the vote of the lesser of: 14 (1) 67% or more of the shares present at the meeting, if the holders of more than 50% of the shares of the fund are present or represented by proxy, or (2) more than 50% of the outstanding shares of the fund. Shares of your fund represented in person or by proxy, including shares which abstain or do not vote with respect to the proposal, will be counted for purposes of determining whether there is a quorum at the meeting. Accordingly, an abstention from voting has the same effect as a vote against the proposal. However, if a broker or nominee holding shares in "street name" indicates on the proxy card that it does not have discretionary authority to vote on the proposal, those shares will not be considered present and entitled to vote on the proposal. Thus, a "broker non-vote" has no effect on the voting in determining whether the proposal has been adopted in accordance with clause (1) above, if more than 50% of the outstanding shares (excluding the "broker non-votes") are present or represented. However, for purposes of determining whether the proposal has been adopted in accordance with clause (2) above, a "broker non-vote" has the same effect as a vote against the proposal because shares represented by a "broker non-vote" are considered to be outstanding shares. If the required approval of shareholders is not obtained, your fund will continue to engage in business as a separate mutual fund and the board of trustees will consider what further action may be appropriate. ADDITIONAL INFORMATION ABOUT THE FUNDS Net asset value Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). Each fund generally values its portfolio securities based on market prices or quotations. When market prices are not available or are considered by Pioneer to be unreliable, the fund may use an asset's fair value. Fair value is determined in accordance with procedures approved by the fund's trustees. You buy or sell shares at the net asset value per share calculated on the day of your transaction, adjusted for any applicable sales charge. When you buy Class A shares, you pay an initial sales charge. When you sell Class B or Class C shares, you may pay a CDSC depending on how long you have owned your shares. Choosing a class of shares Each fund offers three classes of shares. Each class has different sales charges and expenses, allowing you to choose the class that best meets your needs. Factors you should consider include: o How long you expect to own the shares o The expenses paid by each class o Whether you qualify for any reduction or waiver of sales charges Your investment professional can help you determine which class meets your goals. Your investment firm may receive different compensation depending upon which class you choose. If you are not a U.S. citizen and are purchasing shares outside the U.S., you may pay different sales charges under local laws and business practices. Distribution plans Each fund has adopted a distribution plan for each class of shares in accordance with Rule 12b-1 under the Investment Company Act of 1940. Under each plan, the fund pays distribution and service fees to the distributor. Because these fees are an ongoing expense, over time they increase the cost of your investment and your shares may cost more than shares that are not subject to a distribution fee but subject to other sales charges. 15 Comparing classes of shares - ---------------------------------------------------------------------------------------------------------------- Class A - ---------------------------------------------------------------------------------------------------------------- Why you might prefer Class A shares may be your best each class alternative if you prefer to pay an initial sales charge and have lower annual expenses, or if you qualify for any reduction or waiver of the initial sales charge. Initial sales charge Up to 4.5% for Tax-Free Income Fund and 3.5% for Intermediate Tax-Free Fund of the offering price, which is reduced or waived for large purchases and certain types of investors. At the time of your purchase your investment firm may receive a commission from the distributor of up to 4% for Tax- Free Income Fund and 3% for Intermediate Tax-Free Fund, declining as the size of your investment increases. Contingent deferred None, except in certain circumstances sales charges when the initial sales charge is waived. Distribution and service fees Up to 0.25% of average daily net assets. Annual expenses (including Lower than Class B or Class C. distribution and service fees) Exchange privilege Class A shares of other Pioneer mutual funds. - ---------------------------------------------------------------------------------------------------------------------------- Class B Class C - ---------------------------------------------------------------------------------------------------------------------------- Why you might prefer You may prefer Class B shares if you You may prefer Class C shares if you each class do not want to pay an initial sales do not wish to pay an initial sales charge, or if you plan to hold your charge and you would rather pay investment for at least six years for higher annual expenses over time. Intermediate Tax-Free Fund or four years for Intermediate Tax Free Fund. Class B shares are not recommended if you are investing $250,000 or more. Initial sales charge None None Contingent deferred Up to 4% for Tax-Free Income Fund A 1% charge if you sell your shares sales charges and 3% for Intermediate Tax-Free Fund within one year of purchase.

Annual expenses (including Higher than Class A shares; Class B Higher than Class A shares; Class C distribution and service fees) shares convert to Class A shares after shares do not convert to any other eight years for Tax-Free Income Fund class of shares. You continue to pay and six years for Intermediate Tax-Free higher annual expenses. Fund. Exchange privilege Class B shares of other Pioneer Class C shares of other Pioneer mutual funds. mutual funds. Sales charges: Class A shares You pay the offering price when you buy Class A shares unless you qualify to purchase shares at net asset value. You pay a lower sales charge as the size of your investment increases. You do not pay a sales charge when you reinvest dividends or distribution paid by the fund. Investments of $1 million or more You do not pay a sales charge when you purchase Class A shares if you are investing $1 million or more, or you are a participant in certain group plans. However, you pay a contingent deferred sales charge if you sell your Class A shares within one year of purchase. The contingent deferred sales charge is equal to 1% of your investment or your sales proceeds, whichever is less. Reduced sales charges You may qualify for a reduced Class A sales charge if you own or are purchasing shares of Pioneer mutual funds. If you or your investment professional notifies the distributor of your eligibility for a reduced sales charge at the time of your purchase, the distributor will credit you with the combined value (at the current offering price) of all your Pioneer mutual fund shares and the shares of your spouse and the shares of any children under 21. Certain trustees and fiduciaries may also qualify for a reduced sales charge. For this purpose, 16 Pioneer mutual funds include any fund for which the distributor is principal underwriter and, at the distributor's discretion, may include funds organized outside the U.S. managed by Pioneer.

Otherwise, your price per share will be calculated at the close of the New York Stock Exchange after the distributor receives your order. Your investment firm is responsible for submitting your order to the distributor. Buying You may buy fund shares from any investment firm that has a sales agreement with the distributor. If you do not have an investment firm, please call 1-800-225-6292 for information on how to locate an investment professional in your area. You can buy fund shares at the offering price. The distributor may reject any order until it has confirmed the order in writing and received payment. The fund reserves the right to stop offering any class of shares. Minimum investment amounts Your initial investment must be at least $1,000. Additional investments must be at least $100 for Class A shares and $500 for Class B or Class C shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. Exchanging You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000 unless the fund you are exchanging into has a different minimum. The fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred sales charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. Selling Your shares will be sold at net asset value per share next calculated after the fund receives your request in good order.

This may take up to 15 calendar days from the purchase date. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below.

You cannot obtain a signature guarantee from a notary public. Fiduciaries and corporations are required to submit additional documents to sell fund shares. Minimum account size The fund requires that you maintain a minimum account value of $500. If you hold less than the minimum in your account because you have sold or exchanged some of your shares, the fund will notify you of its intent to sell your shares and close your account. You may avoid this by increasing the value of your account to at least the minimum within six months of the notice from the fund. Telephone access You may have difficulty contacting the fund by telephone during times of market volatility or disruption in telephone service. If you are unable to reach the fund by telephone, you should communicate with the fund in writing. Share certificates Normally, your shares will remain on deposit with the transfer agent and certificates will not be issued. Under certain legal circumstances, you may request a certificate for your Class A shares only. A fee may be charged for this service. Other policies The fund may suspend payment of sale proceeds under certain circumstances. The fund or the distributor may revise, suspend or terminate the account options and services available to shareholders at any time. Dividends and capital gains The fund declares a dividend from any net investment income and any net short-term capital gains each business day. You begin earning dividends on the first business day following receipt of payment for shares; your shares continue to earn dividends up to and including the date you redeem them. Dividends are normally paid on the last business day of the month or shortly thereafter. The fund distributes net long-term capital gains, if any, in November. The fund may also pay dividends and distributions at other times if necessary for the fund to avoid federal income or excise tax. If you invest in the fund close to the time that the fund makes a capital gains distribution, generally you will pay a higher price per share and you will pay taxes on the amount of the capital gains distribution whether you reinvest the distribution or receive it as cash. Sales and exchanges may be taxable transactions to shareholders. 22 Taxes For federal income tax purposes, your distributions from the fund's net long-term capital gains (capital gain dividends) are considered long-term capital gains. Dividends the fund pays from its tax-exempt interest income will be designated as exempt-interest dividends and will be treated as tax-exempt interest for federal income tax purposes, although they may increase a shareholder's liability for alternative minimum tax in certain circumstances. Dividends (other than capital gain dividends and exempt-interest dividends) and short-term capital gain distributions are taxable as ordinary income. Dividends and distributions are taxable, whether you take payment in cash or reinvest them to buy additional fund shares. You may also have tax consequences (generally, a capital gain or loss) when you sell or exchange fund shares. Each year the fund will mail to you information about your dividends and distributions for, and the shares you sold in, the previous calendar year. You must provide your social security number or other taxpayer identification number to the fund along with the certifications required by the Internal Revenue Service when you open an account. If you do not or if it is otherwise legally required to do so, the fund will withhold 31% "backup withholding" tax from your dividends (other than exempt-interest dividends) and distributions, sales proceeds and any other payments to you. You should ask your own tax adviser about any federal or state tax considerations, including possible additional withholding taxes for non-U.S. shareholders. You may also consult the fund's statement of additional information for a more detailed discussion of federal income tax considerations that may affect the fund and its shareholders. 23 FINANCIAL HIGHLIGHTS Pioneer Intermediate Tax-Free Fund Selected Data for a Class A Share Outstanding Throughout Each Period: Six Months Ended June 30, 1998 ------------- Net asset value, beginning of period ............................ $ 10.45 Increase (decrease) from investment operations: Net investment income (loss) .................................... $ 0.21 Net realized and unrealized gain (loss) on investments ..........

Alamo Direct, a third-party solicitation firm, has agreed to provide proxy solicitation services to your fund at a cost of approximately $5,000. The costs of the proxy and solicitation will be borne jointly by the funds. Revoking proxies A fund shareholder signing and returning a proxy has the power to revoke it at any time before it is exercised: o By filing a written notice of revocation with Pioneering Services Corporation, 60 State Street, Boston, Massachusetts 02109, or o By returning a duly executed proxy with a later date before the time of the meeting, or o If a shareholder has executed a proxy but is present at the meeting and wishes to vote in person, by notifying the secretary of your fund (without complying with any formalities) at any time before it is voted Being present at the meeting alone does not revoke a previously executed and returned proxy. Outstanding shares and quorum As of January 29, 1999, 5,524,948 Class A shares, 324,235 Class B shares and 95,191 Class C shares of beneficial interest of your fund were outstanding. Only shareholders of record on February 1, 1999 (the record date) are entitled to notice of and to vote at the meeting. A majority of the outstanding shares of your fund that are entitled to vote will be considered a quorum for the transaction of business. Other business Your fund's board of trustees knows of no business to be presented for consideration at the meeting other than the proposal. If other business is properly brought before the meeting, proxies will be voted according to the best judgment of the persons named as proxies. Adjournments If a quorum is not present in person or by proxy at the time any session of the meeting is called to order, the persons named as proxies may vote those proxies that have been received to adjourn the meeting to a later date. If a quorum is present but there are not sufficient votes in favor of the proposal, the persons named as proxies may propose one or more adjournments of the meeting to permit further solicitation of proxies concerning the proposal. Any adjournment will require the affirmative vote of a majority of your fund's shares at the session of the meeting to be adjourned. If an adjournment of the meeting is proposed because there are not sufficient votes in favor of the proposal, the persons named as proxies will vote those proxies favoring the proposal in favor of adjournment, and will vote those proxies against the reorganization against adjournment. Telephone voting In addition to soliciting proxies by mail, by fax or in person, your fund may also arrange to have votes recorded by telephone by officers and employees of your fund or by personnel of the adviser or transfer agent. The telephone voting procedure is designed to verify a shareholder's identity, to allow a shareholder to authorize the voting of shares in accordance with the shareholder's instructions and to confirm that the voting instructions have been properly recorded. If these procedures were subject to a successful legal challenge, these telephone votes would not be counted at the meeting. Your fund has not obtained an opinion of counsel about telephone voting, but is currently not aware of any challenge. o A shareholder will be called on a recorded line at the telephone number in the fund's account records and will be asked to provide the shareholder's social security number or other identifying information o The shareholder will then be given an opportunity to authorize proxies to vote his or her shares at the meeting in accordance with the shareholder's instructions o To ensure that the shareholder's instructions have been recorded correctly, the shareholder will also receive a confirmation of the voting instructions by mail o A toll-free number will be available in case the voting information contained in the confirmation is incorrect 27 o If the shareholder decides after voting by telephone to attend the meeting, the shareholder can revoke the proxy at that time and vote the shares at the meeting OWNERSHIP OF SHARES OF THE FUNDS To the knowledge of the fund, as of December 31, 1998, the following persons owned of record or beneficially 5% or more of the outstanding Class A, Class B and Class C shares of your fund and Tax-Free Income Fund: - --------------------------------------------------------------------------------------------------------- Pro forma ownership of Tax-Free Income Fund as of Names and addresses of owners of Intermediate Tax-Free December 31, 1998 more than 5% of shares ----------------------------- ------------------------------- Class A Class B Class C Class A Class B Class C - --------------------------------------------------------------------------------------------------------- Merrill Lynch, Pierce, Fenner & Smith Incorporated for the Sole Benefit of its Customers -- 32.37% 71.63% -- 20.09% 35.37% 4800 Deer Lake Drive East, 2nd Floor Jacksonville, FL 32246-6484 - --------------------------------------------------------------------------------------------------------- Pioneer Funds Distributor, Inc. 60 State Street -- -- 12.90% -- -- 3.14% Boston, MA 02109-1800 - --------------------------------------------------------------------------------------------------------- Alice M.

This Agreement is intended to be and is adopted as a plan of reorganization within the meaning of Section 368(a)(1) of the United States Internal Revenue Code of 1986, as amended (the "Code"). The reorganization will consist of the transfer of all of the assets of the Acquired Fund to the Acquiring Fund in exchange for the issuance of Class A, Class B and Class C shares of beneficial interest of the Acquiring Fund (the "Acquiring Fund Shares") to the Acquired Fund and the assumption by the Acquiring Fund of the liabilities of the Acquired Fund, followed by the distribution by the Acquired Fund, on or promptly after the Closing Date hereinafter referred to, of the Acquiring Fund Shares to the shareholders of the Acquired Fund in liquidation and termination of the Acquired Fund as provided herein, all upon the terms and conditions hereinafter set forth in this Agreement. In consideration of the premises of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows: 1. TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ACQUIRING FUND SHARES AND LIQUIDATION OF THE ACQUIRED FUND 1.1 The Acquired Fund will transfer all of its assets (consisting, without limitation, of portfolio securities and instruments, dividends and interest receivables, cash and other assets), as set forth in the statement of assets and liabilities referred to in paragraph 7.2 hereof (the "Statement of Assets and Liabilities"), to the Acquiring Fund free and clear of all liens and encumbrances, except as otherwise provided herein in exchange for (i) the assumption by the Acquiring Fund of all known and unknown liabilities of the Acquired Fund, including the liabilities set forth in the Statement of Assets and Liabilities, which shall be assigned and transferred to and assumed by the Acquiring Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund, for distribution pro rata by the Acquired Fund to its shareholders in proportion to their respective ownership of Class A, Class B and/or Class C shares of beneficial interest of the Acquired Fund, as of the close of business on the closing date (the "Closing Date"), of a number of Acquiring Fund Shares having an aggregate net asset value equal to the value of the assets, less such liabilities (herein referred to as the "net value of the assets"), of the Acquired Fund so transferred, assumed, assigned and delivered, all determined as provided in paragraph 2 and as of a date and time as specified therein. Such transactions shall take place at the closing provided for in paragraph 3.1 hereof (the "Closing"). All computations shall be provided by Pioneer Investment Management, Inc. (the "Administrator"), as administrator for the Acquiring Fund and for the Acquired Fund and shall be recomputed by Arthur Andersen LLP, independent auditors of the Acquiring Fund. The determination of the Administrator, as recomputed by said auditors, shall be conclusive and binding on all parties in interest. 1.2 The Acquired Fund has provided the Acquiring Fund with a list of the current securities holdings 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 (except to the extent sales may be limited by representations made in connection with issuance of the tax opinion described in paragraph 8.7 hereof) but will not, without the prior approval of the Acquiring Fund, acquire any additional securities other than securities of the type in which the Acquiring Fund is permitted to invest. 1.3 Each of the Acquiring Fund and the Acquired Fund shall bear its own expenses in connection with the transactions contemplated by this Agreement. 1.4 On or as soon after the Closing Date as is conveniently practicable (the "Liquidation Date"), the Acquired Fund will liquidate and distribute pro rata to shareholders of record ("the Acquired Fund shareholders"), determined as of the close of regular trading on the New York Stock Exchange on the last day such Exchange is open for unrestricted trading immediately preceding the Closing Date (the "Valuation Date"), the Acquiring Fund Shares received by the Acquired Fund pursuant to paragraph 1.1. Such liquidation and distribution will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of the Acquired Fund on the books of the Acquiring Fund, to open accounts on the share records of the Acquiring Fund in the names of the Acquired Fund shareholders and representing the respective pro rata number of Acquiring Fund Shares due such shareholders. Acquired Fund shareholders who own Class A shares of the Acquired Fund will receive Class A Acquiring Fund Shares, Acquired Fund shareholders who own Class B shares of the Acquired Fund will receive Class B Acquiring Fund Shares and Acquired Fund shareholders who own Class C shares of the Acquired Fund will receive Class C Acquiring Fund Shares. The Acquiring Fund will not issue share certificates representing Acquiring Fund Shares unless a shareholder specifically requests the Acquiring Fund Shares in certificated form and, if applicable, in exchange for outstanding certificates representing Acquired Fund shares, as described in paragraph 1.5. 1.5 The Acquiring Fund shall record the net asset value of all outstanding Acquired Fund certificated shares in its books and records as of the Closing Date, in accordance with paragraph 2.2, and daily thereafter, in accordance with the Acquiring Fund's procedures for 29 determining net asset value per share. The Acquiring Fund will honor certificates representing Acquired Fund shares at their net asset value as determined on the books and records of the Acquiring Fund, and subject to the Acquiring Fund's normal requirements for redeeming or transferring shares evidenced by certificates. Acquired Fund shareholders need not surrender such certificates or deliver affidavits with respect to lost certificates after the Closing. Any Acquired Fund certificate which remains outstanding on the Closing Date shall be deemed to be evidence of ownership of the same class of shares of beneficial interest of the Acquiring Fund. 1.6 Any transfer taxes payable upon issuance of Acquiring Fund Shares in a name other than the registered holder of the Acquiring 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 Acquiring Fund Shares are to be issued and transferred. 1.7 The Acquired Fund shall file an application (on Form N-8F or such other form deemed appropriate by the Securities and Exchange Commission (the "Commission")) pursuant to Section 8(f) of the Investment Company Act of 1940, as amended (the "1940 Act"), as soon as practicable following the Liquidation Date, and the existence of the Acquired Fund shall be terminated in accordance with Massachusetts law as promptly as practicable thereafter. 2. VALUATION 2.1 The net asset values of the Class A, Class B and Class C Acquiring Fund Shares and the net value of the assets and liabilities of the Acquired Fund attributable to its Class A, Class B and Class C shares to be transferred shall, in each case, be determined as of the close of the New York Stock Exchange on the Valuation Date. The net asset value per share of Acquiring Fund Shares shall be computed by the Administrator in the manner set forth in the Agreement and Declaration of Trust or By-Laws of the Acquiring Fund and then-current prospectus and statement of additional information of the Acquiring Fund and shall be computed to not fewer than six decimal places. The net value of the assets of the Acquired Fund to be transferred shall be computed by the Administrator by calculating the value of the assets attributable to each class of shares transferred by the Acquired Fund and by subtracting therefrom the amount of the liabilities attributable to each class of shares to be assigned and transferred to and assumed by the Acquiring Fund on the Closing Date, said assets and liabilities to be valued in the manner set forth in the Acquired Fund's most recent prospectus and statement of additional information. 2.2 The number of shares of each class of Acquiring Fund Shares to be issued (including fractional shares, if any) in exchange for the Acquired Fund's assets shall be determined by dividing the value of the Acquired Fund assets attributable to a class, less the liabilities attributable to that class assumed by the Acquiring Fund, by the Acquiring Fund's net asset value per share of the same class, all as determined in accordance with paragraph 2.1. 2.3 All computations of value shall be made by the Administrator in accordance with its regular practice as pricing agent for the Acquiring Fund. 3. CLOSING AND CLOSING DATE 3.1 The Closing Date shall be as of ___________, 1999, or as of such other date on or before ___________, 1999 as the parties may agree in writing. The Closing shall be held at 5:00 p.m., Boston time, at the offices of the Acquiring Fund, 60 State Street, Boston, Massachusetts 02109, or at such other time and/or place as the parties may agree in writing. 3.2 Portfolio securities that are not held in book-entry form in the name of Brown Brothers Harriman & Co. (the "Custodian") as record holder for the Acquired Fund shall be presented by the Acquired Fund to the Custodian for examination no later than five business days preceding the Valuation Date. Portfolio securities which are not held in book-entry form shall be delivered by the Acquired Fund to the Custodian for the account of the Acquiring 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, and shall be accompanied by all necessary federal and state stock transfer stamps or a check for the appropriate purchase price thereof. Portfolio securities held of record by the Custodian in book-entry form on behalf of the Acquired Fund shall be delivered to the Acquiring Fund by the Custodian by recording the transfer of ownership thereof on its records. The cash delivered shall be in the form of currency or by the Custodian crediting the Acquiring Fund's account maintained with the Custodian with immediately available funds. 3.3 In the event that on the proposed Valuation 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 said Exchange or elsewhere shall be disrupted so that accurate appraisal of the value of the net assets of the Acquiring Fund or the Acquired Fund is impracticable, the Closing Date shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored; provided that if trading shall not be fully resumed and reporting restored on or before , 1999, this Agreement may be terminated by the Acquiring Fund or the Acquired Fund upon the giving of written notice to the other party. 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 Acquired Fund shareholders and the number and percentage ownership of outstanding shares of each class of shares of beneficial interest of the Acquired Fund owned by each such shareholder, all as of the close of business on the Valuation Date, certified by its Treasurer, Secretary or other authorized officer (the "Shareholder List"). The Acquiring 30 Fund shall issue and deliver to the Acquired Fund a confirmation evidencing the Acquiring Fund Shares to be credited on the Liquidation Date, or provide evidence satisfactory to the Acquired Fund that such Acquiring Fund Shares have been credited to the Acquired Fund's account on the books of the Acquiring Fund. At the Closing each party shall deliver to the other such bills of sale, checks, assignments, certificates, receipts or other documents as such other party or its counsel may reasonably request. 4.

Bonds in the index have a minimum credit rating of BBB, were part of at least a $50 million issuance made within the past five years and have a maturity of at least two years. Index returns are calculated monthly, assume reinvestment of dividends and, unlike fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in the index. Past performance does not guarantee future results. Return and share price fluctuate, and your shares, when redeemed, may be worth more or less than their original cost. 37 Pioneer Intermediate Tax-Free Fund Portfolio Management Discussion 6/30/98 Dear Shareowner, Pioneer Intermediate Tax-Free Fund closed the first half of its fiscal year on June 30, 1998. During that time, favorable economic conditions in the United States and a "flight to quality" in the U.S. Treasury market pushed taxable bond prices higher and long-term interest rates to historic lows. Even so, an increased supply of municipal bonds combined with weak demand to restrain the performance of munis, especially when compared to taxable bonds. Kathleen D. McClaskey has managed Pioneer Intermediate Tax-Free Fund for the past 11 years, leading the investment team responsible for the fund's daily management. In the following discussion, Ms. McClaskey reviews the investment environment and the strategies that affected your fund's performance and provides her outlook for the second half of 1998. Q: How did the fund perform? A: For the six month period ended June 30, the fund's Class A shares returned 1.69%, Class B 1.29% and Class C 1.15%, all at net asset value. In comparison, the 151 intermediate municipal debt funds followed by Lipper Analytical Services returned 2.05% for the same period. (Returns do not reflect sales charges.) We attribute your fund's slight lag in performance to its investment standards. Over the past six months, the fund maintained an emphasis on higher-rated bonds. Other funds in this category often invest in lower-rated bonds, which often provide higher returns since they involve greater risk. The fund's Class A shares provided a tax-free 30-day yield of 3.31% on June 30. That translated into an attractive taxable-equivalent yield of 5.49% for an investor in the maximum 39.6% tax bracket. Q: Did the situation in Asia affect U.S. interest rates and bonds? A: The uncertainty of the Asian crisis kept interest rates, and bond prices, within a narrow range for most of the period. It also sparked a "flight to quality." Generally, investors waited for new developments and evidence of the situation's effect on the U.S. economy. When the crisis worsened this spring, investors sought the safety and security of U.S. treasuries. This demand again pushed up prices of taxable bonds and lowered interest rates. Asia's problems held down U.S. interest rates for another reason, too. Many investors were concerned that our strong economy eventually might stimulate inflation and lead the Federal Reserve to raise interest rates. But, because the United States and Asia are active trading partners, slowing Asian economies could lessen U.S. economic growth. That would ease inflationary pressures and reduce the Fed's impetus to change rates. Q: What was the environment like for municipal bonds over the past six months? A: Basically it was a case of supply and demand. The supply of municipal bonds increased dramatically during the first half of 1998, as many state and local governments took advantage of lower interest rates to refinance existing bonds or to finance new projects. In fact, this period included the largest transaction ever to occur in the tax-exempt market--Long Island Power Authority's $6.5 billion issue. Ironically, all this good news for municipalities didn't help municipal bond investors much, since the flood of supply kept prices from rising. In addition, the continuing economic problems in Asia increased the popularity of U.S. Treasury bonds, particularly among foreign investors. Municipal bond prices rose, but not as fast or far as treasuries. The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on December 31, 1997 to 5.63% on June 30. In comparison, the yield on the Lehman Brothers Municipal Bond Index--a good indicator of the municipal bond market--only fell from 4.70% on December 31 to 4.65% on June 30. Q: What strategies did you use to manage the fund? A: We sought to maximize income and total return by maintaining high standards of quality and emphasizing relative value. During the period, lower-quality bonds provided little yield advantage over higher rated bonds. In that scenario, we believed higher-quality bonds represented better relative value. As of June 30, 90% of the fund's holdings were rated AA or above, translating into an average rating of "AA." (Ratings apply to underlying securities, not fund shares.) The portfolio remained well diversified with 57 holdings spread over 32 states. We increased total return potential by maintaining the portfolio's duration--it rose slightly from 6.63 years on December 31 to 6.68 years on June 30. Duration measures a fund's sensitivity to changes in interest rates. Generally, an investment's price will change 1% for every 1% change in interest rates. Higher durations mean more potential for both price appreciation when interest rates fall and price declines when interest rates rise; shorter durations reduce interest rate sensitivity. We implemented this strategy by selling bonds with nearing "call dates" and reinvesting in bonds with 15- to 20-year non-callable maturities. Call provisions set a predetermined date for an issuer to repurchase a bond from its holder. Often, this happens when interest 38 rates decline so that an issuer can refinance the bonds at lower rates. Selling callable bonds improved the fund's potential for both price appreciation and long-term income generation for several reasons. Bonds with longer maturities offer better potential for price appreciation when interest rates decline, and longer streams of predictable income. Q: What is your outlook for municipal bonds over the next six months? A: Over the near-term, we expect many of the trends that were positive for municipal bonds during the past six months to continue through the end of 1998. We believe solid economic growth and minimal inflation in the United States can spur ongoing improvement in the financial health of municipalities. After the recent flood of offerings, we think issuers are taking a breather, which should give tax-exempt bond prices a lift. Looking out further, we expect Asia to have a powerful influence on interest rates. If there is a significant spillover into the U.S. economy, interest rates could remain stable or move moderately lower. 39 Pioneer Tax-Free Income Fund Investment Returns (Class A Shares) The mountain chart on the right shows the growth of a $10,000 investment made in Pioneer Tax-Free Income Fund, compared to the growth of the Lehman Brothers Municipal Bond Index. - ------------------------------------------------------------------------ Average Annual Total Returns (As of June 30, 1998) Period Net Asset Value Public Offering Price* 10 Years 8.19% 7.70% 5 Years 5.81 4.83 1 Year 8.51 3.58 - ------------------------------------------------------------------------ * Reflects deduction of the maximum 4.5% sales charge at the beginning of the period and assumes reinvestment of distributions at net asset value.

Bonds in the index have a minimum credit rating of BBB, were part of at least a $50 million issuance made within the past five years and have a maturity of at least two years. Index returns are calculated monthly, assume reinvestment of dividends and, unlike fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in the index. A portion of the fund's income may be subject to the Alternative Minimum Tax (AMT). Past performance does not guarantee future results. Return and share price fluctuate, and your shares, when redeemed, may be worth more or less than their original cost. 40 Pioneer Tax-Free Income Fund Portfolio Management Discussion 6/30/98 Dear Shareowner, Pioneer Tax-Free Income Fund closed the first half of its fiscal year on June 30, 1998. During that time, favorable economic conditions in the United States and a "flight to quality" in the U.S. Treasury market pushed taxable bond prices higher and long-term interest rates to historic lows. Even so, an increased supply of municipal bonds, combined with weak demand, hurt the performance of munis, especially when compared to taxable bonds. Mark L. Winter has managed Pioneer Tax-Free Income Fund for the past 12 years, leading the investment team responsible for the fund's daily activities. The following discussion with Mr. Winter details the investment environment and the strategies that affected your fund's performance and provides his outlook for the second half of 1998. Q: How did the fund perform in the first half of 1998? A: Pioneer Tax-Free Income Fund delivered competitive returns. For the six months, Class A shares returned 2.46%, Class B shares 2.16% and Class C shares 2.08%, all at net asset value. In comparison, the 246 general municipal debt funds followed by Lipper Analytical Services returned 2.26% for the same period. (Returns do not reflect sales charges.) Lipper Analytical Services is an independent company that tracks fund performance. The fund's Class A shares also provided a tax-free 30-day yield of 3.84% on June 30. That translated into an attractive taxable-equivalent yield of 6.35% for an investor in the 39.6% maximum federal tax bracket. Q: Did the situation in Asia affect U.S. interest rates and bonds? A: The uncertainty of the Asian crisis kept interest rates, and bond prices, within a narrow range for most of the period. It also sparked a "flight to quality." Generally, investors waited for new developments and evidence of the situation's effect on the U.S. economy. When the crisis worsened this spring, investors sought the safety and security of U.S. treasuries. This demand again pushed up prices of taxable bonds and lowered interest rates. Asia's problems held down U.S. interest rates for another reason, too. Many investors were concerned that our strong economy eventually might stimulate inflation and lead the Federal Reserve to raise interest rates. But, because the United States and Asia are active trading partners, slowing Asian economies could lessen U.S. economic growth. That would ease inflationary pressures and reduce the Fed's impetus to change rates. Q: What was the environment like for municipal bonds over the past six months? A: Basically it was a case of supply and demand. The supply of municipal bonds increased dramatically during the first quarter of 1998, as many state and local governments took advantage of lower interest rates to refinance higher-cost bonds or to finance new projects. In fact, this period included the largest transaction ever to occur in the tax-exempt market--Long Island Power Authority's $6.5 billion issue. Ironically, all this good news for municipalities didn't help municipal bond investors much since the flood of supply kept prices from rising. In addition, the continuing economic problems in Asia increased the popularity of U.S. Treasury bonds, particularly among foreign investors. Municipal bond prices rose but not as fast or far as treasuries. The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on December 31, 1997 to 5.63% on June 30. In comparison, the yield on the Lehman Brothers Municipal Bond Index--a good indicator of the municipal bond market--only fell from 4.70% on December 31 to 4.65% on June 30. Q: What strategies did you use to manage the fund? A: We emphasized total return and income by adjusting the fund's sensitivity to interest rate changes. We also maintained the fund's high standards of quality and focused on attractive relative value. As of June 30, 54% of the fund's holdings were insured AAA-rated bonds, translating into an average rating of "AA+." (Ratings apply to underlying securities, not fund shares.) The portfolio remained well diversified with 178 holdings spread over 41 states. We increased total return potential by increasing the portfolio's duration from 6.44 years on December 31 to 7.70 years on June 30. Duration measures a fund's sensitivity to changes in interest rates. Generally, an investment's price will change 1% for every 1% change in interest rates. Higher durations mean more potential for both price appreciation when interest rates fall and price declines when interest rates rise; shorter durations reduce interest rate sensitivity. We implemented this strategy by selling bonds with nearing "call dates" and reinvesting in bonds with 15 to 20 year maturities because "call" provisions relate to a predetermined date for an issuer to repurchase a bond from its holder. Often, this happens when interest rates decline so that an issuer can refinance the bonds at lower rates. Selling callable bonds improved the fund's potential for both price appre- 41 ciation and long-term income generation for several reasons. Bonds with longer maturities offer better potential for price appreciation when interest rates decline, and longer streams of predictable income. Q: What is your outlook for municipal bonds over the next six months? A: Over the near-term, we expect many of the trends that were positive for municipal bonds during the past six months to continue through the end of 1998. We believe solid economic growth and minimal inflation in the United States can spur ongoing improvement in the financial health of municipalities. After the recent flood of offerings, we think issuers are taking a breather, which should give tax-exempt bond prices a lift. Looking out further, we expect Asia to have a powerful influence on interest rates. If there is a significant spillover into the U.S. economy, interest rates could remain stable or move moderately lower.
