                    NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

                             SCHEDULED FOR [ ], 2005

To the Shareholders of the AmSouth Funds:

     A joint special meeting of shareholders (the "Meeting") for each of the
AmSouth Funds will be held at the offices of [ ], [ ], on [ ]at [ ] [a/p].m.,
local time, to consider the following:

     1.   With respect to each AmSouth Fund, a proposal to approve an Agreement
          and Plan of Reorganization. Under the Agreement and Plan of
          Reorganization applicable to your AmSouth Fund, it will transfer all
          of its assets to an investment company or a series thereof (each a
          "Pioneer Fund") managed by Pioneer Investment Management, Inc.
          ("Pioneer") in exchange for Class A, B and Y shares of the Pioneer
          Fund (or, in the case of Pioneer Institutional Money Market Fund,
          Class 1, 2 and 3 shares). Class A, B and Y shares of the Pioneer Fund
          will be distributed to each AmSouth Fund's shareholders in proportion
          to their Class A, B and I share holdings on the reorganization date.
          In the case of Pioneer Institutional Money Market Fund, Class 1, 2 and
          3 shares will be distributed in exchange for Institutional Class 1
          shares, Institutional Class 2 shares and Institutional Class 3 shares
          of AmSouth Institutional Money Market Fund. The Pioneer Fund also will
          assume your AmSouth Fund's liabilities that are included in the
          calculation of your AmSouth Fund's net asset value on the closing date
          at the reorganization. In the case of certain AmSouth Funds, the
          Pioneer Fund is an existing mutual fund with a substantially similar
          investment objective and similar investment policies as your AmSouth
          Fund. In the case of other AmSouth Funds, the Pioneer Fund is a newly
          organized mutual fund with a substantially similar investment
          objective and similar investment policies as your AmSouth Fund.
          Following the reorganization, your AmSouth Fund will then be
          dissolved. As a result of the reorganization, you will become
          shareholders of the Pioneer Fund. Your board of trustees recommends
          that you vote FOR this proposal.

     2.   Any other business that may properly come before the Meeting.

     Shareholders of record as of the close of business on [ ], 2005, are
entitled to vote at the Meeting and any related follow-up meetings.

     Whether or not you expect to attend the Meeting, please complete and return
the enclosed proxy card. If shareholders do not return their proxies in
sufficient numbers, your AmSouth Fund may be required to make additional
solicitations.

                                        By order of the Board of Trustees,

                                        [           ]

     Shares of the Pioneer Funds have not been approved or disapproved by the
Securities and Exchange Commission (the "SEC"). The SEC has not passed upon the
accuracy or adequacy of this prospectus. Any representation to the contrary is a
criminal offense.

     An investment in any AmSouth Fund or Pioneer Fund (each sometimes referred
to herein as a "Fund") is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

     This combined proxy statement and prospectus (the "Proxy
Statement/Prospectus"), dated [ ], 2005, is being furnished to shareholders of
the AmSouth Funds in connection with the solicitation by the board of trustees
(the "Board", or the "Trustees") of the AmSouth Funds of proxies to be used at a
joint meeting of shareholders of the AmSouth Funds (the "Meeting") to be held at
the offices of [ ], [ ], on [ ], 2005 at [ ] [a/p].m., local time. Each AmSouth
Fund is a series of AmSouth Funds, an open-end management investment company
organized as a Massachusetts business trust. Each Pioneer Fund is an open-end
management investment company, or a series thereof, organized as either a
Delaware statutory trust or a Massachusetts business trust.

     The Proxy Statement/Prospectus contains information you should know before
voting on the approval of a proposed Agreement and Plan of Reorganization (each
a "Plan") that provides for the reorganization of each AmSouth Fund into a
corresponding Pioneer Fund (each a "Reorganization"). The following table
indicates (a) the corresponding Pioneer Fund shares that each AmSouth Fund
shareholder would receive if each Plan is approved, (b) which AmSouth Fund
shareholders may vote on which proposals and on what page of this Proxy
Statement/Prospectus the discussion regarding each proposal begins. On each
proposal, all shareholders of an AmSouth Fund, regardless of the class of shares
held, will vote together as a single class. Although each Reorganization is
similar in structure, you should read carefully the specific discussion
regarding your AmSouth Fund's Reorganization.

     The Proxy Statement/Prospectus sets forth the information about the Pioneer
Fund that a prospective investor ought to know before investing and should be
retained for future reference. Additional information about each Pioneer Fund
has been filed with the SEC and is available upon oral or written request and
without charge. See "Where to Get More Information."

Background to the Reorganizations

     AmSouth Asset Management Inc. ("AAMI") is investment adviser to the AmSouth
Funds and a wholly-owned subsidiary of AmSouth Bank, which in turn is wholly
owned by AmSouth Bancorporation. AmSouth Bank and AAMI have determined that
engaging in the business of investment adviser to the AmSouth Funds is not a
core business that AAMI intends to continue. After investigating and discussing
several alternatives for ongoing investment management of the AmSouth Funds with
the Trustees, AmSouth Bank and AAMI conducted a search for a buyer for AAMI's
fund management business.


                                       4


Ultimately, AmSouth Bank and AAMI decided to recommend to the Board that the
AmSouth Funds be reorganized into similar mutual funds managed by Pioneer
Investment Management, Inc. ("Pioneer").

     The Board met twice in May 2005 and again in June 2005. At these meetings,
your Trustees received and evaluated materials regarding Pioneer and the Pioneer
Funds, including the performance record and expense structure of each of the
Pioneer Funds, the impact of the proposed Reorganizations on the AmSouth Funds'
shareholders, and the quality of the services offered by Pioneer. The Trustees
also considered other alternatives for the ongoing management of AmSouth Funds.
At a meeting on May 18, 2005, the Trustees met with representatives of Pioneer.
In addition to these general factors, the Trustees also considered the factors
discussed below in the context of each Reorganization. At the May 18, 2005
meeting, all of the Trustees who are not interested persons of AAMI (the
"Independent Trustees") met separately in executive session with counsel to the
Independent Trustees and requested and received such information from AAMI and
Pioneer as they determined to be necessary and appropriate to evaluate the
proposed Reorganizations. On June 23, 2005, the Board, including all of the
Independent Trustees, unanimously voted to approve each of the Reorganizations.
In approving the Reorganizations, the Board determined that the Reorganizations
were in the best interests of the AmSouth Funds' shareholders and the interests
of existing AmSouth Funds' shareholders will not be diluted as a result of the
Reorganizations.

     Pioneer believes that it can offer capable management and favorable
long-term investment performance to the AmSouth Funds' shareholders. The
Reorganizations will, by combining the assets of two mutual funds and by
increasing distribution capabilities, offer the potential for increased
economies of scale. Increased economies of scale have the potential of
benefiting the shareholders of your AmSouth Funds and the Pioneer Funds by
spreading fixed costs over a larger asset base and reducing expenses on a per
share basis. There can be no assurance that such economies of scale will be
realized.

Why the Trustees Are Recommending the Reorganizations

     The Trustees believe that reorganizing your AmSouth Fund into a portfolio
with a substantially similar investment objective and similar investment
policies that is part of the Pioneer family of funds offers you potential
benefits. These potential benefits and considerations include:

     o    AmSouth Bank and AAMI have determined that engaging in the business of
          investment adviser to the AmSouth Funds is not a core business that
          AAMI intends to continue. Therefore, a change in your AmSouth Fund's
          investment adviser is necessary. In the absence of the Reorganization,
          such change would be more likely to motivate shareholders invested in
          reliance on AAMI's role to withdraw from the Fund, thereby reducing
          the fund size and increasing fund expense ratios;

     o    The track record of Pioneer in managing the Pioneer Funds;

     o    The transaction will qualify as a tax free reorganization under
          Section 368(a) of the Internal Revenue Code of 1986, as amended (the
          "Code") and there fore will not be treated as a taxable sale of your
          AmSouth shares;

     o    In the case of certain AmSouth Funds, the potential for lower
          management fees and total expenses;

     o    The resources of Pioneer, including its infrastructure in shareholder
          services; and

     o    The opportunity to be part of a significantly larger family of funds,
          with additional product offerings and enhanced shareholder servicing
          options, and a stronger compliance structure.

     For further information, please see the individual descriptions of the
proposals contained in this Proxy Statement/Prospectus.

How Each Reorganization Will Work

     o    AmSouth Fund shareholder-directed exchanges and purchases made by
          check, [ACH], or wire will be accepted up until [ ] [a/p].m. ([ ]
          Time) on [ ]day, [ ], 2005. Exchange and purchase requests received
          after this deadline will be rejected and returned. Purchase and
          exchange requests made by AmSouth Fund shareholders through financial
          institutions or advisers must be made earlier to ensure the trade can
          be processed within this deadline. Financial institutions and advisers
          that trade electronically (NSCC) with the AmSouth Funds can place
          exchange and purchase requests up until [ ] [a/p].m. ([ ] Time) on [
          ]day, [ ], 2005. Exchanges and purchases received after this deadline
          will be rejected and returned. The AmSouth Funds will not process
          purchases made via automatic investment method (AIM) after [ ], 2005.
          Dividend/capital gain reinvestment and established systematic
          exchanges will continue through [ ], 2005.


                                       5


     o    Each AmSouth Fund will transfer all of its assets to a corresponding
          Pioneer Fund. Each Pioneer Fund will assume the corresponding AmSouth
          Fund's liabilities that are included in the calculation of such
          AmSouth Fund's net asset value on the day on which each Reorganization
          closes (the "Closing Date"). Liabilities of each Fund to its
          shareholders not assumed by a corresponding Pioneer Fund will be
          assumed by AmSouth Bancorporation.

     o    Each Pioneer Fund will issue Class A, B and Y shares to the
          corresponding AmSouth Fund in amounts equal to the aggregate net asset
          value of that AmSouth Fund's Class A, B and I shares. Shareholders of
          your AmSouth Fund will receive Class A, B and Y shares of the
          corresponding Pioneer Fund. These shares will be distributed to
          shareholders in proportion to the relative net asset value of their
          share holdings on the Closing Date. On the Closing Date, each
          shareholder will hold shares of the Pioneer Fund with the same
          aggregate net asset value as the shares of the AmSouth Fund that the
          shareholder held immediately prior to the Reorganization.

     o    Each AmSouth Fund will be dissolved after the Closing Date.

     o    Pioneer acts as investment adviser to each Pioneer Fund.

     o    The Reorganizations are intended to result in no income, gain or loss
          being recognized for federal income tax purposes to any of the Pioneer
          Funds, the AmSouth Funds or the shareholders of the AmSouth Funds.

     o    In recommending each of the Reorganizations, the Trustees of your
          AmSouth Fund have determined that the Reorganization is in the best
          interest of your AmSouth Fund and will not dilute the interests of
          shareholders of your AmSouth Fund. The Trustees have made that
          determination on the basis of the factors listed above and discussed
          in more detail under each proposal. A reorganization might not be in
          the best interest of the shareholders of a mutual fund if the
          surviving fund had higher expenses, less experienced management or the
          adviser did not have adequate resources to manage the affairs of the
          mutual fund.

     o    If the Reorganizations are approved, the AmSouth Funds will file with
          the SEC an application for deregistration on Form N-8F under the
          Investment Company Act of 1940, as amended (the "Investment Company
          Act"), and will cease to exist as an investment company when such
          application is approved.

Who Is Pioneer

     Pioneer is registered as an investment adviser under the Investment
Advisers Act of 1940, as amended, and acts as investment adviser to mutual funds
and institutional accounts. Pioneer or its predecessors have been managing
mutual funds since 1928 and at December 31, 2004 had, together with its
affiliates, over $42 billion in assets under management. Pioneer is an indirect,
wholly owned subsidiary of UniCredito Italiano S.p.A., an Italian Bank.

     In addition to the Class A, B and Y shares to be issued in the
Reorganization, each Pioneer Fund also offers Class C shares (subject to a
contingent deferred sales charge and a Rule 12b-1 Plan). In addition, most of
the Pioneer Funds also offer Class R shares (which are offered only to certain
retirement plans).

Who Bears the Expenses Associated with the Reorganizations

     Pioneer and AmSouth Bancorporation will pay all costs of preparing and
printing the AmSouth Funds' proxy statements and solicitation costs incurred by
the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be
responsible for all costs and expenses of the AmSouth Funds in connection with
the Reorganizations.

Will Pioneer and AmSouth Bancorporation Benefit from the Reorganizations

     Pioneer will benefit from managing a larger pool of assets. Pioneer is also
acquiring certain assets associated with AAMI's fund management business and the
benefits of certain restrictive covenants on AAMI's and AmSouth Bancorporation's
activities. In consideration for the acquisition of these assets, the
opportunity to manage additional assets and covenants from AmSouth
Bancorporation and AAMI, including their assistance in facilitating the
Reorganizations, noncompetition covenants and their obligation to indemnify
Pioneer against certain liabilities, Pioneer has agreed to pay AAMI $65 million.
This amount is subject to partial repayment in the event that the assets
attributable to the AmSouth Funds are


                                       6


redeemed (subject to certain conditions, including threshold amounts) from the
Pioneer Funds within four years after the closing of the Reorganization.

     Pioneer will also agree to provide an affiliate of AAMI with ongoing
servicing payments with respect to the Class Y shares issued in the
Reorganizations. This additional compensation will be equal on an annual basis
to 0.10% of the average daily net assets attributable to the Class Y shares held
by former AmSouth Funds' shareholders. This payment would be made by Pioneer and
not the Pioneer Funds. No additional compensation would be paid with respect to
Class A or Class B shares; however, if an affiliate of AAMI is the broker of
record, that affiliate would receive the trail commissions under the Class A and
Class B Rule 12 b-1 Plans.

What Happens if a Reorganization Is Not Approved

     If the required approval of shareholders is not obtained, the Meeting may
be adjourned as more fully described in this Proxy Statement/Prospectus, your
AmSouth Fund will continue to engage in business as a separate mutual fund and
the Board will consider what further action may be appropriate.

Who Is Eligible to Vote

     Shareholders of record on [ ], 2005 are entitled to attend and vote at the
Meeting or any adjournment of the Meeting. On each proposal, all shareholders of
an AmSouth Fund, regardless of the class of shares held, will vote together as a
singe class. Each share is entitled to one vote. Shares represented by properly
executed proxies, unless revoked before or at the Meeting, will be voted
according to shareholders' instructions. If you sign a proxy but do not fill in
a vote, your shares will be voted to approve the Agreement and Plan of
Reorganization. If any other business comes before the Meeting, your shares will
be voted at the discretion of the persons named as proxies.

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement

that are not in the summary.

     Each Fund invests primarily in equity securities of large capitalization
issuers and, consequently, the Funds have similar investment policies and risks.
In the table below, if a row extends across the entire table, the policy
disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:


                                       8


     o    The stock market goes down (this risk may be greater in the short
          term)

     o    Large company or growth stocks fall out of favor with investors

     o    The adviser's/subadviser's judgment about the attractiveness, growth
          potential or potential appreciation of a particular stock proves to be
          incorrect

     Pioneer Oak Ridge Large Cap Growth Fund may be subject to the following
additional risks associated with investing in non-U.S. issuers, which may
involve unique risks compared to investing in securities of U.S. issuers. These
risks are more pronounced to the extent the Fund invests in issuers in countries
with emerging markets or if the Fund invests significantly in one country. These
risks may include:

     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, the adviser/subadviser might not be able to sell the
          Fund's portfolio securities at times, in amounts and at prices it
          considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     In addition, at times, more than 25% of Pioneer Oak Ridge Large Cap Growth
Fund's assets may be invested in the same market segment, such as financial or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

     AmSouth Capital Growth Fund is subject to risks relating to the fact that
it is non-diversified. The Fund may invest in a small number of companies which
may increase the volatility of the Fund. Accordingly, the Fund's portfolio may
be more sensitive to changes in the market value of a single company or
industry.

     Although Pioneer Oak Ridge Large Cap Growth Fund is classified as a
diversified investment company, the Fund's portfolio may be comprised of fewer
issuers than many large cap growth funds. Typically, the subadviser expects the
portfolio to include a limited number of different issuers, which may increase
the volatility of the Fund's net asset value per share.

Past Performance

     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)  The quoted returns reflect the performance from 4/1/96 to 3/12/00 of the
     ISG Capital Growth Fund, an open-end investment company that was the
     predecessor fund to the AmSouth Capital Growth Fund. The ISG Capital Growth
     Fund commenced operations on 4/1/96 through a transfer of assets from
     certain collective trust fund ("commingled") accounts managed by First
     American National Bank, using substantially the same investment objective,
     policies and methodologies as the Fund. The quoted before-tax returns of
     the Fund includes the performance of the predecessor fund and commingled
     accounts for periods dating back to 7/31/93, and prior to the Fund's
     commencement of operations, restated to reflect the expenses associated
     with the Fund. The commingled accounts were not registered with the SEC
     and, therefore, were not subject to the investment restrictions imposed by
     law on registered mutual funds. If the commingled accounts had been
     registered, the commingled accounts' performance may have been adversely
     affected. After-tax returns reflect performance since 4/1/96, and do not
     include the performance of the commingled accounts prior to that date.
     Class A shares were first offered on 4/1/96.

(2)  Performance for the Class B shares, which were first offered on 2/5/98, is
     based on the historical performance of the Fund's Class A shares, including
     the performance of the predecessor fund and commingled accounts (without
     sales charge), prior to that date. The predecessor fund and commingled
     accounts were managed using substantially the same investment objective,
     policies and methodologies as the Fund. The historical performance of the
     Class B shares has been restated to reflect the Fund's Class B shares
     distribution (12b-1) fees and the contingent deferred sales charge.

(3)  Performance for the Class I shares, which were first offered on 10/3/97, is
     based on the historical performance of the Fund's Class A shares, including
     the performance of the predecessor fund and commingled accounts (without
     sales charge), prior to that date. The predecessor fund and commingled
     accounts were managed using substantially the same investment objective,
     policies and methodologies as the Fund.

(4)  The S&P 500/Barra Growth Index, an unmanaged index of 500 stocks, is for
     reference only, does not mirror the Fund's investments, and reflects no
     deduction for fees, expenses or taxes.

The table above shows the impact of taxes on AmSouth Capital Growth Fund's
returns. After-tax returns are only shown for Class A shares and Class I shares
and may vary for Class B shares. The Fund's after-tax returns are calculated
using the highest individual federal marginal income tax rates and do not
reflect the impact of state and local taxes. In certain cases, the figure
representing "Return After Taxes on Distributions and Sale of Fund Shares" may
be higher than the other return figures for the same period. A higher after-tax
return results when a capital loss occurs upon redemption and translates into an
assumed tax deduction that benefits the shareholder. Please note that actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. Also note that after-tax returns shown are not relevant to
shareholders who hold Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts.

The Pioneer Fund's past performance does not necessarily indicate how it will
perform in the future. Pursuant to an agreement and plan of reorganization, the
Pioneer Fund acquired all of the assets and those liabilities reflected in the
net assets of Oak Ridge Large Cap Equity Fund (the predecessor fund) on February
13, 2004. In the reorganization, the predecessor fund exchanged all of its
assets for Class A shares of the Pioneer Fund. The predecessor fund offered only
one class of shares which


                                       11


was most similar to Class A shares of the Pioneer Fund. As a result of the
reorganization, the Pioneer Fund is the accounting successor of the predecessor
fund, which commenced operations on March 1, 1999. The Pioneer Fund's subadviser
served as the predecessor fund's investment adviser. The performance of each
class of the Pioneer Fund includes the performance of the predecessor fund's
shares prior to the reorganization, which has been restated to reflect
differences in any applicable sales charges and Rule 12b-1 fees (but not other
differences in expenses). This adjustment had the effect of reducing the
previously reported performance of the predecessor fund.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares of the Pioneer Fund bought as
     part of an investment of $1 million or more are not subject to an initial
     sales charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.49% for Class A
     shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

(7)  The expenses in the table above reflect the expense limitations currently
     in effect for the Pioneer Fund, under which Pioneer has contractually
     agreed to limit ordinary operating expenses to the extent required to
     reduce fund expenses to 1.30%, and 2.20% of the average daily net assets
     attributable to Class A and Class B shares, respectively. These expense
     limitations are in effect through April 1, 2008 for Class A shares and
     through April 1, 2006 for Class B shares. There can be no assurance that
     Pioneer will extend the expense limitations beyond such time.

(8)  The expenses in the table above reflect the expense limitation in effect
     for Class B shares of the Pioneer Fund, under which Pioneer has
     contractually agreed to limit ordinary operating expenses to the extent
     required to reduce fund expenses 2.10% of the average daily net assets

     April 1, 2007. There can be no assurance that Pioneer will extend the
     expense limitations beyond such time.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Capital Growth Fund and its shareholders. The Trustees
considered the following matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the historical investment performance of Pioneer Oak Ridge Large
Cap Growth Fund is significantly better than your AmSouth Fund's investment
performance. For the one and five year periods ended December 31, 2004, Class A
shares of Pioneer Oak Ridge Large Cap Growth Fund had an average annual return
of 4.96% (one year); and -0.54% (five year), compared to an average annual
return of the Class A shares of your AmSouth Fund of -1.94% (one year); and
- -6.34% (five year), respectively, during the same period. In addition, the
Trustees considered the track record of Pioneer in managing equity and fixed
income mutual funds.


                                       15


     Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over
80 investment companies and accounts with approximately $42 billion in assets,
including $26.7 billion in equity securities. Pioneer is part of the global
asset management group of UniCredito Italiano S.p.A., one of the largest banking
groups in Italy, providing investment management and financial services to
mutual funds, institutional and other clients. As of December 31, 2004, assets
under management of UniCredito Italiano S.p.A. were approximately $175 billion
worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges

     Fourth, Pioneer Oak Ridge Large Cap Growth Fund's management fee (0.75% of
average daily net assets) is lower than the advisory fee of your AmSouth Fund
(0.80% of average daily net assets). The historical gross and net expenses of
Pioneer Oak Ridge Large Cap Growth Fund attributable to Class A are slightly
higher than your AmSouth Fund's historical gross and net expenses. However, the
estimated pro forma expenses of the Pioneer Fund attributable to Class A and Y
shares after giving effect to the Reorganizations on both a gross and net basis
are lower than your AmSouth Fund's gross and net operating expenses for the
Class A and I shares. The estimated pro forma expenses for Class B shares will
be lower on a gross basis, but higher on a net basis. The Board considered the
positive factors associated with the Reorganization, such as the superior
performance of the Pioneer Fund, to outweigh the negative factors, such as the
increase in net operating expenses for the Class B shares. The aggregate Rule
12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder
servicing fees paid by the Class A and Class B shares of both Funds are the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that is not paid by the Pioneer Fund's Class Y shares. In
addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduced per share expenses.

     Fifth, the substantially larger size of the combined Pioneer Oak Ridge
Large Cap Growth Fund will offer greater opportunity for diversification of the
investment portfolio, which should help to reduce risks.

     Sixth, the Class A, B and Y shares of Pioneer Oak Ridge Large Cap Growth
Fund received in the Reorganization will provide AmSouth Capital Growth Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Seventh, The transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares. Although
the Reorganization will result in a per share increase in net unrealized capital
gains and decrease in capital loss carryforwards, the potential negative tax
consequences of these aspects of the Reorganization are outweighed by the
advantages of the Reorganization.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth
Funds in connection with the Reorganization. AAMI will otherwise be responsible
for all costs and expenses of the AmSouth Funds in connection with the
Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also
sets forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth Large Cap Fund approve the reorganization
of their fund into Pioneer Oak Ridge Large Cap Growth Fund.

It is impossible to predict how many shares of the Pioneer Fund will actually be
received and distributed by your AmSouth Fund on the Reorganization date. The
table should not be relied upon to determine the amount of the Pioneer Fund's
shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    Large company or growth stocks fall out of favor with investors

     o    The adviser's/subadviser's judgment about the attractiveness, growth
          potential or potential appreciation of a particular stock proves to be
          incorrect


                                       8


     Pioneer Oak Ridge Large Cap Growth Fund may be subject to the following
additional risks associated with investing in non-U.S. issuers, which may
involve unique risks compared to investing in securities of U.S. issuers. These
risks are more pronounced to the extent the Fund invests in issuers in countries
with emerging markets or if the Fund invests significantly in one country. These
risks may include:

     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, the adviser/subadviser might not be able to sell the
          Fund's portfolio securities at times, in amounts and at prices it
          considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     In addition, at times, more than 25% of Pioneer Oak Ridge Large Cap Growth
Fund's assets may be invested in the same market segment, such as financials or
technology. To the extent the Fund emphasizes investments in a market segment,
the fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

     Although the Pioneer Oak Ridge Large Cap Growth Fund is classified as a
diversified investment company, the Fund's portfolio may be comprised of fewer
issuers than many large cap growth funds. Typically, the subadviser expects the
portfolio to include a limited number of different issuers, which may increase
the volatility of the Fund's net asset value per share.

Past Performance

     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     The Pioneer Fund's past performance does not necessarily indicate how it
will perform in the future. Pursuant to an agreement and plan of reorganization,
the Pioneer Fund acquired all of the assets and those liabilities reflected in
the net assets of Oak Ridge Large Cap Equity Fund (the predecessor fund) on
February 13, 2004. In the reorganization, the predecessor fund exchanged all of
its assets for Class A shares of the Fund. The predecessor fund offered only one
class of shares which was most similar to Class A shares of the Pioneer Fund. As
a result of that reorganization, the Pioneer Fund is the accounting successor of
the predecessor fund, which commenced operations on March 1, 1999. The Pioneer
Fund's subadviser served as the predecessor fund's investment adviser. The
performance of each class of the Pioneer Fund includes the performance of the
predecessor fund's shares prior to the 2004 reorganization, which has been
restated to reflect differences in any applicable sales charges and Rule 12b-1
fees (but not other differences in expenses). This adjustment had the effect of
reducing the previously reported performance of the predecessor fund.

The table above shows the impact of taxes on AmSouth Large Cap Fund's returns.
After-tax returns are only shown for Class A shares and Class I shares and may
vary for Class B shares. The Fund's after-tax returns are calculated using the
highest individual federal marginal income tax rates and do not reflect the
impact of state and local taxes. In certain cases, the figure representing
"Return After Taxes on Distributions and Sale of Fund Shares" may be higher than
the other return figures for the same period. A higher after-tax return results
when a capital loss occurs upon redemption and translates into an assumed tax
deduction that benefits the shareholder. Please note that actual after-tax
returns depend on an investor's tax situation and may differ from those shown.
Also note that after-tax returns shown are not relevant to investors who hold
their Fund shares through tax-deferred arrangements, such as 401(k) plans or
individual retirement accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares bought as part of an
     investment of $1 million or more are not subject to an initial sales
     charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.47% for Class A
     shares, 0.47% for Class B shares and 0.32% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

(7)  The expenses in the table above reflect the expense limitations currently
     in effect for the Pioneer Fund, under which Pioneer has contractually
     agreed to limit ordinary operating expenses to the extent required to
     reduce fund expenses to 1.30%, and 2.20% of the average daily net assets
     attributable to Class A and Class B shares, respectively. These expense
     limitations are in effect through April 1, 2008 for Class A shares and
     through April 1, 2006 for Class B shares. There can be no assurance that
     Pioneer will extend the expense limitations beyond such time.

(8)  The expenses in the table above reflect the expense limitation in effect
     for Class B shares of the Pioneer Fund, under which Pioneer has
     contractually agreed to limit ordinary operating expenses to the extent
     required to reduce fund expenses 2.10% of the average daily net assets
     attributable Class B shares. This expense limitation is in effect through
     April 1, 2007. There can be no assurance that Pioneer will extend the
     expense limitations beyond such time.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same,. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Large Cap Fund and its shareholders. The Trustees
considered the following matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the historical investment performance of Pioneer Oak Ridge Large
Cap Growth Fund is significantly better than your AmSouth Fund's investment
performance. For the one and five year periods ended December 31, 2004, Class A
shares of Pioneer Oak Ridge Large Cap Growth Fund had an average annual return
of 4.96% (one year) and -0.54% (five year); compared to an average annual return
of the Class A shares of your AmSouth Fund of -0.53% (one year); and -3.62%
(five year); respectively, during the same period. In addition, the Trustees
considered the track record of Pioneer in managing equity and fixed income
mutual funds.

     Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over
80 investment companies and accounts with approximately $42 billion in assets,
including $26.7 billion in equity securities. Pioneer is part of the global
asset management group of UniCredito Italiano S.p.A., one of the largest banking
groups in Italy, providing investment management


                                       15


and financial services to mutual funds, institutional and other clients. As of
December 31, 2004, assets under management of UniCredito Italiano S.p.A. were
approximately $175 billion worldwide. Shareholders of your AmSouth Fund would
become part of a significantly larger family of funds that offers a more diverse
array of investment options and enhanced shareholder account options. The
Pioneer family of mutual funds offers over 80 funds, including domestic and
international equity and fixed income funds and a money market fund that will be
available to your AmSouth Fund's shareholders through exchanges.

     Fourth, Pioneer Oak Ridge Large Cap Growth Fund's management fee (0.75% of
average daily net assets) is lower than the advisory fee of your Fund (0.80% of
average daily net assets). Although the historical gross and net expenses of
Pioneer Oak Ridge Large Cap Growth Fund are higher than your Fund's historical
gross and net expenses (except for Class Y shares), the estimated pro forma
expenses of Class A and Class Y Shares of the Pioneer Fund after giving effect
to the Reorganizations on both a gross and net basis are lower than your Fund's
gross and net operating expenses for the Class A and I shares. Although the pro
forma operating expenses for the Class B shares are estimated to increase
slightly, this increase is partly the result of expense limitations on your
AmSouth Fund that are voluntary and may be discontinued at any time. AmSouth
Bank and its affiliates have informed the trustees that they will discontinue
their expense limitations in the future. The trustees considered the positive
factors associated with the Reorganization, such as the superior performance of
the Pioneer Fund, to outweigh the negative factors, such as the increase in
expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees
and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B
shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares
pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's
Class Y shares. In addition, the broader distribution arrangements of the
Pioneer Fund offer greater potential for further asset growth and reduced per
share expenses.

     Fifth, the substantially larger size of the combined Pioneer Oak Ridge
Large Cap Growth Fund will offer greater opportunity for diversification of the
investment portfolio, which should help to reduce risks.

     Sixth, the Class A, B and Y shares of Pioneer Oak Ridge Large Cap Growth
Fund received in the Reorganization will provide AmSouth Large Cap Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Seventh, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AAMI will pay all costs of preparing and printing the Funds'
proxy statements and solicitation costs incurred by the Funds in connection with
the Reorganization. AAMI will otherwise be responsible for all costs and
expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also
sets forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth Capital Growth Fund approve the
reorganization of their fund into Pioneer Oak Ridge Large Cap Growth Fund.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                                  PROPOSAL 1(c)

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

     Each Fund invests primarily in the equity securities of large cap U.S.
issuers and, consequently, has similar investment policies and risks. Your Fund,
while not a pure index fund, seeks to track closely the S&P 500 Stock Index,
while the Pioneer Fund is actively managed and does not have a goal of tracking
an index. In the table below, if a row extends across the entire table, the
policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

                                  The subadviser's stock selection process
                                  utilizes computer-aided quantitative
                                  analysis. The subadviser's computer models
                                  use many types of data, but emphasize
                                  technical data such as price and volume
                                  information. Applying these models to stocks
                                  within the S&P 500, the subadviser hopes to
                                  generate more capital growth than that of the
                                  S&P 500. The subadviser's emphasis on
                                  technical analyses can result in significant
                                  shifts in portfolio holdings at different

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    In the case of the Pioneer Fund, value stocks fall out of favor with
          investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     o    Stocks selected for income do not achieve the same return as
          securities selected for capital growth

Past Performance

     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)  Class A shares were first offered on 9/1/98. Performance for the Class B
     shares, which were first offered on 9/2/98, is based on the historical
     performance of the Fund's Class A shares (without sales charge) prior to
     that date. The historical performance of the Class B shares has been
     restated to reflect the Fund's Class B shares distribution (12b-1) fees and
     the contingent deferred sales charge.

(2)  Performance for the Class I shares, which were first offered on 12/11/98,
     is based on the historical performance of the Fund's Class A shares
     (without sales charge) prior to that date.

     not mirror the Fund's investments, and reflects no deduction for fees,

The above table shows the impact of taxes on AmSouth Enhanced Market Fund's
returns. After-tax returns are only shown for Class A shares and may vary for
Class B shares. The Fund's after-tax returns are calculated using the highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. In certain cases, the figure representing "Return After
Taxes on Distributions and Sale of Fund Shares" may be higher than the other
return figures for the same period. A higher after-tax return results when a
capital loss occurs upon redemption and translates into an assumed tax deduction
that benefits the shareholder. Please note that actual after-tax returns depend
on an investor's tax situation and may differ from those shown. Also note that
after-tax returns shown are not relevant to shareholders who hold Fund shares
through tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares bought as part of an
     investment of $1 million or more are not subject to an initial sales
     charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.56% for Class A
     shares, 0.56% for Class B shares and 0.41% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  Pioneer Fund pays a management fee that ranges from 0.50% to 0.70% of
     average daily net assets based on its performance.

(7)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Enhanced Market Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, after the Reorganization, the combined Fund will have an asset size
substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

     Third, the historical investment performance of Pioneer Fund is superior to
your AmSouth Fund's investment performance. For the one and five year periods
ended December 31, 2004, Class A shares of Pioneer Fund had an average annual
return of 5.21% (one year); and -1.44% (five year); compared to an average
annual return of the Class A shares of your AmSouth Fund of 3.98% (one year);
and -3.99% (five year), respectively, during the same period. In addition, the
Trustees considered the track record of Pioneer in managing equity and fixed
income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $26.7 billion in equity securities. Pioneer is part of the
global asset management group of UniCredito Italiano S.p.A., one of the largest
banking groups in Italy, providing investment management and financial services
to mutual funds, institutional and other clients. As of December 31, 2004,
assets under management of UniCredito Italiano S.p.A. were approximately $175
billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

     Fifth, the Trustees recognized that Pioneer Fund's operating expenses for
Class A and Class B shares, both gross and net of expense limitations, and its
management fee, are higher than your Fund's expenses for Class A and Class B
shares and your Fund's management fee. They also noted that on a pro forma
basis, after giving effect to the Reorganization, the expenses of the Pioneer
Fund's Class A and Class B shares were estimated to be higher that your Fund's
expenses for Class A and Class B shares both on a gross and a net basis, though
the gross and net expenses of your Fund's Class I shares would decline. The
Trustees noted that the differential in fees can be explained by the fact that
the Pioneer Fund is more actively managed, while the AmSouth Fund is an enhanced
index fund, and index funds traditionally have substantially lower fees than
actively


                                       13


managed funds. The Trustees considered that the other advantages of the
Reorganization were sufficient to make up for the higher expenses of the Pioneer
Fund. The Trustees also considered that the aggregate Rule 12b-1 distribution
and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees
paid by the Class A and Class B shares of both Funds are the same. Moreover,
your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee
that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader
distribution arrangements of the Pioneer Fund offer greater potential for
further asset growth and reduced per share expenses.

     Sixth, the substantially larger size of Pioneer Fund will offer greater
opportunity for diversification of the investment portfolio, which should help
to reduce risks.

     Seventh, the Class A, B and Y shares of Pioneer Fund received in the
Reorganization will provide AmSouth Enhanced Market Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Eighth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares. Although
the Reorganization will result in a per share increase in net unrealized capital
gains and decrease in capital loss carryforwards, the potential negative tax
consequences of these aspects of the Reorganization are outweighed by the
advantages of the Reorganization.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

     Each Fund invests primarily in equity securities of U.S. issuers using a
value oriented investment approach and, consequently, the Funds have similar
investment policies and risks. In the table below, if a row extends across the
entire table, the policy disclosed applies to both your AmSouth Fund and the
Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

   Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

   o  The stock market goes down (this risk may be greater in the short term)

   o  Value stocks fall out of favor with investors

   o  The Fund's assets remain undervalued or do not have the potential value
      originally expected

   Pioneer Value Fund may be subject to the following additional risks
associated with investing in non-U.S. issuers, which may involve unique risks
compared to investing in securities of U.S. issuers. These risks are more
pronounced to the extent the Fund invests in issuers in countries with emerging
markets or if the Fund invests significantly in one country. These risks may
include:

   o  Less information about non-U.S. issuers or markets may be available due to
      less rigorous disclosure or accounting standards or regulatory practices

   o  Many non-U.S. markets are smaller, less liquid and more volatile. In a
      changing market, the adviser/subadviser might not be able to sell the
      Fund's portfolio securities at times, in amounts and at prices it
      considers reasonable


                                       8


   o  Adverse effect of currency exchange rates or controls on the value of the
      Fund's investments

   o  The economies of non-U.S. countries may grow at slower rates than expected
      or may experience a downturn or recession

   o  Economic, political and social developments may adversely affect the
      securities markets

   o  Withholding and other non-U.S. taxes may decrease the Fund's return

   In addition, at times, more than 25% of Pioneer Value Fund's assets may be
invested in the same market segment, such as financials or technology. To the
extent the Fund emphasizes investments in a market segment, the Fund will be
subject to a greater degree to the risks particular to the industries in that
segment, and may experience greater market fluctuation, than a fund without the
same focus.

Past Performance

   Set forth below is performance information for each Fund. The bar charts show
how each Fund's total return (not including any deduction for sales charges) has
varied from year to year for each full calendar year. The tables show average
annual total return (before and after taxes) for each Fund over time for each
class of shares (including deductions for sales charges) compared with a
broad-based securities market index. The bar charts give an indication of the
risks of investing in each Fund, including the fact that you could incur a loss
and experience volatility of returns year to year. Past performance before and
after taxes does not indicate future results.

(1)  Class A shares were first offered on 12/1/88. Performance for the Class B
     shares, which were first offered on 9/3/97, is based on the historical
     performance of the Fund's Class A shares (without sales charge) prior to
     that date. The historical performance of the Class B shares has been
     restated to reflect the Fund's Class B shares distribution (12b-1) fees and
     the contingent deferred sales charge.

(2)  Performance for the Class I shares, which were first offered on 9/2/97, is
     based on the historical performance of the Fund's Class A shares (without
     sales charge) prior to that date.

(3)  The S&P 500/Barra Value Index, an unmanaged market capitalization weighted
     index comprised of a subset of the S&P 500 with low price to book ratios

     the Fund's investments, and reflects no deduction for fees, expenses or
     taxes.

The table above shows the impact of taxes on AmSouth Value Fund's returns.
After-tax returns are only shown for Class A and Class I shares and may vary for
Class B shares. The Fund's after-tax returns are calculated using the highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. In certain cases, the figure representing "Return After
Taxes on Distributions and Sale of Fund Shares" may be higher than the other
return figures for the same period. A higher after-tax return results when a
capital loss occurs upon redemption and translates into an assumed tax deduction
that benefits the shareholder. Please note that actual after-tax returns depend
on an investor's tax situation and may differ from


                                       10


those shown. Also note that after-tax returns shown are not relevant to
investors who hold their Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares bought as part of an
     investment of $1 million or more are not subject to an initial sales
     charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%,


                                       12


     3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of
     shares acquired in the ISG combination), Class B shares automatically
     convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.52% for Class A
     shares, 0.52% for Class B shares and 0.37% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  Pioneer Value Fund pays a management fee that ranges from 0.50% to 0.70% of
     average daily net assets based on its performance. The Fund's basic fee
     before any performance adjustment is 0.60% of average daily net assets,
     which fee is reduced at asset levels above $5 billion.

(7)  Pioneer Value Fund's total annual operating expenses have not been reduced
     by any expense offset arrangements.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Value Fund. The Trustees considered the following matters,
among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment


                                       13


adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

     Second, after the Reorganization, the combined Fund will have an asset size
substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

     Third, the historical investment performance of Pioneer Value Fund is
comparable to your AmSouth Fund's investment performance. For the one, five and
ten year periods ended December 31, 2004, Class A shares of Pioneer Value Fund
had an average annual return of 5.78% (one year); 4.42% (five year); and 8.34%
(ten year), compared to an average annual return of the Class A shares of your
AmSouth Fund of 8.78% (one year); 1.02% (five year); and 9.62% (ten year),
respectively, during the same period. In addition, the Trustees considered the
track record of Pioneer in managing equity and fixed income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

     Fifth, Pioneer Value Fund's management fee (0.60% of average daily net
assets as of as of March 31, 2005) is substantially lower than the advisory fees
of your Fund (0.80% of average daily net assets). The aggregate Rule 12b-1
distribution and shareholder servicing fees and non-Rule 12b-1 shareholder
servicing fees paid by the Class A and Class B shares of both Funds are the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that is not paid by the Pioneer Fund's Class Y shares. Pioneer
Value Fund's expenses are lower than your Fund's expenses on both a gross and
net basis. On a pro forma basis, after giving effect to the Reorganization, it
is estimated that the Pioneer Value Fund's expenses will also be lower than you
Fund's expenses on a gross and net basis. In addition, the broader distribution
arrangements of the Pioneer Fund offer greater potential for further asset
growth and reduced per share expenses.

     Sixth, the substantially larger size of the combined Pioneer Value Fund
will offer greater opportunity for diversification of the investment portfolio,
which should help to reduce risks.

     Seventh, the Class A, B and Y shares of Pioneer Value Fund received in the
Reorganization will provide AmSouth Value Fund shareholders with exposure to
substantially the same investment product as they currently have.

     Eighth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares. Although
the Reorganization will result in a per share decrease in capital loss
carryforwards, the potential negative tax consequences of this aspect of the
Reorganization are outweighed by the advantages of the Reorganization.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

It is impossible to predict how many shares of the Pioneer Fund will actually be
received and distributed by your AmSouth Fund on the Reorganization date. The
table should not be relied upon to determine the amount of the Pioneer Fund's
shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                                  PROPOSAL 1(e)

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

     Each Fund invests primarily in equity securities of mid capitalization
issuers and, consequently, has similar investment policies and risks. Your Fund,
while not a pure index fund, seeks to track closely the S&P MidCap 400 Index,
while the Pioneer Fund is actively managed and does not have a goal of tracking
an index. In the table below, if a row extends across the entire table, the
policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    Value or Mid-Cap stocks fall out of favor with investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     Each Fund also has risks associated with investing in mid-size companies.
Compared to large companies, mid-size companies, and the market for their equity
securities, are likely to:

     o    Be more sensitive to changes in earnings results and investor
          expectations

     o    Have more limited product lines and capital resources

     o    Experience sharper swings in market values

     o    Be harder to sell at the times and prices the adviser/subadviser
          thinks appropriate

     o    Offer greater potential for gain or loss

     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. These risks may include:


                                       9


     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, the adviser/subadviser might not be able to sell the
          Fund's portfolio securities at times, in amounts and at prices it
          considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     In addition, at times, more than 25% of Pioneer Mid Cap Value Fund's assets
may be invested in the same market segment, such as financial or technology. To
the extent the Fund emphasizes investments in a market segment, the Fund will be
subject to a greater degree to the risks particular to the industries in that
segment, and may experience greater market fluctuation, than a fund without the
same focus.

Past Performance

     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)  The quoted returns reflect the performance from 5/4/99 to 3/12/00 of the
     ISG Mid-Cap Fund, an open-end investment company that was the predecessor
     fund to the AmSouth Mid Cap Fund. The predecessor fund was managed using

The table above shows the impact of taxes on AmSouth Mid Cap Fund's returns.
After-tax returns are only shown for Class A and Class I shares and may vary for
Class B shares. The Fund's after-tax returns are calculated using the highest
individual


                                       11


federal marginal income tax rates and do not reflect the impact of state and
local taxes. In certain cases, the figure representing "Return After Taxes on
Distributions and Sale of Fund Shares" may be higher than the other return
figures for the same period. A higher after-tax return results when a capital
loss occurs upon redemption and translates into an assumed tax deduction that
benefits the shareholder. Please note that actual after-tax returns depend on an
investor's tax situation and may differ from those shown. Also note that
after-tax returns shown are not relevant to investors who hold their Fund shares
through tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares bought as part of an
     investment of $1 million or more are not subject to an initial sales
     charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.


                                       13


(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.20% for Class A
     shares, 0.20% for Class B shares and 0.05% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  Purchases of $1 million or more and purchases by participants in certain
     group plans are not subject to an initial sales charge but may be subject
     to a contingent deferred sales charge of 1%.

(7)  At current asset levels, Pioneer Mid Cap Value Fund pays a management fee
     that ranges from 0.60% to 0.80% of average daily net assets based on its
     performance and the size of the Fund. The Fund's basic fee, before any
     performance adjustment, is 0.70% of average daily net assets, which is
     reduced at asset levels above $500 million.

(8)  Pioneer Mid Cap Value Fund's total annual operating expenses in the table
     have not been reduced by any expense offset arrangements.


     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Mid Cap Fund. The Trustees considered the following
matters, among others, in approving the proposal.


                                       14


     First, AAMI, the investment adviser to your Amsouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, after the Reorganization, the combined Fund will have an asset size
substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

     Third, the historical investment performance of Pioneer Mid Cap Value Fund
is superior to your AmSouth Fund's investment performance. For the one and five
year periods ended December 31, 2004, Class A shares of Pioneer Mid Cap Value
Fund had an average annual return of 14.68% (one year) and 11.40% (five year),
compared to an average annual return of the Class A shares of your AmSouth Fund
of 9.46% (one year) and -5.05% (five year) during the same period. The Trustees
also considered that, for the one and five year periods ended March 31, 2005,
Class A shares of the Pioneer Fund had an average annual return of 17.73% (one
year) and 12.59% (five year), compared to an average annual return of the Class
A shares of your AmSouth Fund of 10.15% (one year) and -6.37% (five year),
respectively, during the same period. In addition, the Trustees considered the
track record of Pioneer in managing equity and fixed income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $26.7 billion in equity funds. Pioneer is part of the global
asset management group of UniCredito Italiano S.p.A., one of the largest banking
groups in Italy, providing investment management and financial services to
mutual funds, institutional and other clients. As of December 31, 2004, assets
under management of UniCredito Italiano S.p.A. were approximately $175 billion
worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges

     Fifth, Pioneer Mid Cap Value Fund's management fee (0.74% of average daily
net assets) is substantially lower than the advisory fee of your Fund (0.90% of
average daily net assets). The aggregate Rule 12b-1 distribution and shareholder
servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A
and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's
Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the
Pioneer Fund's Class Y shares. Currently, the Pioneer Mid Cap Value Fund's gross
expense ratio is below the gross expense ratio of the corresponding class of
your AmSouth Fund. However, your current expense ratio net of expense
limitations is lower than the gross expense ratio of the Pioneer Fund (except
for the Class Y shares of the Pioneer Fund, both the gross and net expenses of
which are lower than the expenses of the Class I shares of the AmSouth Fund). On
a pro forma basis, after giving effect to the Reorganization, it is estimated
that the gross expenses of each class of the Pioneer Fund will be lower than the
gross expenses of the corresponding class of your Fund. Although the net
expenses of the Pioneer Fund's Class A and Class B shares will be higher than
the net expenses of your Fund's Class A and Class B shares, your Fund's expense
limitation is voluntary and may be discontinued at any time. AAMI has informed
the trustees that the expense limitations will be discontinued in the future.
The Trustees also noted that the Pioneer Fund is more actively managed, while
the AmSouth Fund is an enhanced index fund, and index funds traditionally have
substantially lower fees than actively managed funds. In addition, the broader
distribution arrangements of the Pioneer Fund offer greater potential for
further asset growth and reduced per share expenses.

     Sixth, the substantially larger size of the combined Pioneer Mid Cap Value
Fund will offer greater opportunity for diversification of the investment
portfolio, which should help to reduced risks.

     Seventh, the Class A, B and Y shares of Pioneer Mid Cap Value Fund received
in the Reorganization will provide AmSouth Mid Cap Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Eighth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares. Although
the Reorganization will result in a per share increase in net unrealized capital
gains and a decrease in capital loss carryforwards, the potential negative tax
consequences of these aspects of the Reorganization are outweighed by the
advantages of the Reorganization.


                                       15


     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                  The Fund uses a "first-in, first-out" method
                                  to determine how long you have held your
                                  shares. This means that if you purchased
                                  shares on different days, the shares
                                  purchased first will be considered redeemed
                                  first for purposes of determining whether the
                                  redemption fee will be charged.

                                  The fee will be charged on all covered
                                  redemptions and exchanges, including those
                                  made through retirement plan, brokerage and
                                  other types of omnibus accounts (except where
                                  it is not practical for the plan

                                  the fee). The Fund will not impose the
                                  redemption fee on a redemption or exchange of
                                  shares purchased upon the reinvestment of
                                  dividend and capital gain distributions.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down

     o    Small company or growth stocks fall out of favor with investors

     o    The adviser's/subadviser's judgment about the attractiveness, growth
          potential or potential appreciation of a particular stock proves
          incorrect

     Each Fund also has risks associated with investing in small companies.
Compared to large companies, small companies, and the market for their equity
securities, are likely to:


                                       8


     o    Be more sensitive to changes in the economy, earnings results and
          investor expectations

     o    Have more limited product lines and capital resources

     o    Experience sharper swings in market values

     o    Be harder to sell at the times and prices the adviser or subadviser
          thinks appropriate

     o    Offer greater potential for gain or loss

     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. These risks are more pronounced to the
extent the Fund invests in issuers in countries with emerging markets or if the
Fund invests significantly in one country. These risks may include:

     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, the adviser/subadviser might not be able to sell the
          Fund's portfolio securities at times, in amounts and at prices it
          considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     In addition, at times, more than 25% of Pioneer Growth Opportunities Fund's
assets may be invested in the same market segment, such as financial or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

Past Performance

     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pursuant to an agreement and plan of reorganization, Pioneer Growth
Opportunities Fund's Investor Class acquired all of the assets and those
liabilities reflected in the net assets of Safeco Growth Opportunities Fund (the
predecessor fund) on December 10, 2004. In the reorganization, the predecessor
fund exchanged all of its assets for Investor Class shares of the Fund. The
predecessor fund offered an Investor Class and other classes of shares similar
to the Fund's Class A, B and C shares. As a result of the reorganization,
Pioneer Growth Opportunities Fund is the accounting successor of the predecessor
fund. The predecessor fund operated as a registered investment company like the
Fund. The performance of each class of the Fund includes the performance of the
predecessor fund's Class A and Class B shares prior to the reorganization, which
has been restated to reflect differences in any applicable sales charges (but
not differences in expenses). If all the expenses of Pioneer Growth
Opportunities Fund were reflected, the performance would be lower. Since August
2, 2004 and prior to the reorganization, Pioneer served as the predecessor
fund's investment adviser. Previously, Safeco Asset Management Company served as
the predecessor fund's investment adviser. The Fund's Investor Class shares are
not offered in the Reorganization.

(2)  Russell 2000 Growth Index, an unmanaged index of common stocks of small- to
     mid-sized companies, is not available for investment and does not reflect
     fees, brokerage commissions or other expenses of investing.

The table above shows the impact of taxes on AmSouth Small Cap Fund's returns.
After-tax returns are only shown for Class A and Class I shares and may vary for
Class B shares. The Fund's after-tax returns are calculated using the highest
individual federal marginal income tax rates and do not reflect the impact of
state and local taxes. In certain cases, the figure representing "Return After
Taxes on Distributions and Sale of Fund Shares" may be higher than the other
return figures for the same period. A higher after-tax return results when a
capital loss occurs upon redemption and translates into an assumed tax deduction
that benefits the shareholder. Please note that actual after-tax returns depend
on an investor's tax situation and may differ from those shown. Also note that
after-tax returns shown are not relevant to investors who hold their Fund shares
through tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares bought as part of an
     investment of $1 million or more are not subject to an initial sales
     charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  For Class B shares purchased prior to the combination of AmSouth Funds with
     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 30 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.57% for Class A
     shares, 0.57% for Class B shares and 0.42% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  Purchases of $1 million or more and purchases by participants in certain
     group plans are not subject to an initial sales charge but may be subject
     to a contingent deferred sales charge of 1%.

(7)  Other expenses are based on estimated amounts for the current fiscal year.

(8)  Pioneer Growth Opportunities Fund's total annual operating expenses in the
     table have not been reduced by any expense offset arrangements.

(9)  The expenses in the table above reflect the expense limitation in effect
     through May 1, 2006 under which Pioneer has contractually agreed not to
     impose all or a portion of its management fee and, if necessary, to limit
     other ordinary operating expenses to the extent required to reduce Class A
     expenses to 1.30% of the average daily net assets attributable to Class A
     shares; the portion of Fund expenses (including the amount of the
     management fee waived) attributable to Class B and Class Y shares will be
     reduced only to the extent such expenses are reduced for Class A shares.
     There can be no assurance that Pioneer will extend the expense limitation
     beyond May 1, 2006.

(10) Class Y shares of Pioneer Growth Opportunities Fund are being offered for
     the first time in connection with the Reorganization.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Small Cap Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, after the Reorganization, the combined Fund will have an asset size
substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

     Third, the historical investment performance of Pioneer Growth
Opportunities Fund exceeds your AmSouth Fund's investment performance. For the
one and five year periods ended December 31, 2004, Class A shares of Pioneer
Growth Opportunities Fund had an average annual return of 15.19% (one year); and
3.88% (five year); compared to an average annual return of the Class A shares of
your AmSouth Fund of 7.65% (one year); and -1.91% (five year), respectively,
during the same period. In addition, the Trustees considered the track record of
Pioneer in managing equity and fixed income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

     Fifth, Pioneer Fund's management fee (0.65% of average daily net assets) is
substantially lower than the advisory fee of your Fund (0.90% of average daily
net assets). Although the historical gross expenses of Class A shares of Pioneer
Growth


                                       14


Opportunities Fund are higher than your Fund's historical gross expenses for
Class A shares, the historical gross and net expenses for Class B shares of the
Pioneer Fund, and estimated pro forma expenses of the Pioneer Fund attributable
to Class A, B and Y shares after giving effect to the Reorganization on both a
gross and net basis are lower than your Fund's gross and net operating expenses.
The aggregate Rule 12b-1 distribution and shareholder servicing fees and
non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares
of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a
non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class
Y shares. In addition, the broader distribution arrangements of the Pioneer Fund
offer greater potential for further asset growth and reduced per share expenses.

     Sixth, the substantially larger size of the combined Pioneer Growth
Opportunities Fund will offer greater opportunity for diversification of the
investment portfolio, which should help to reduce risks.

     Seventh, the Class A, B and Y shares of Pioneer Growth Opportunities Fund
received in the Reorganization will provide AmSouth Small Cap Fund shareholders
with exposure to substantially the same investment product as they currently
have.

     Eighth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

                                  to determine how long you have held your
                                  shares. This means that if you purchased
                                  shares on different days, the shares
                                  purchased first will be considered redeemed
                                  first for purposes of determining whether the
                                  redemption fee will be charged.

                                  The fee will be charged on all covered
                                  redemptions and exchanges, including those
                                  made through retirement plan, brokerage and
                                  other types of omnibus accounts (except where
                                  it is not practical for the plan
                                  administrator or brokerage firm to implement
                                  the fee). The Fund will not impose the
                                  redemption fee on a redemption or exchange of
                                  shares purchased upon the reinvestment of
                                  dividend and capital gain distributions.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The non-U.S. stock markets go down or perform poorly relative to other
          investments (this risk may be greater in the short term)

     o    Equity securities of non-U.S. issuers or growth stocks fall out of
          favor with investors

     o    The Fund's investments do not have the growth potential originally
          expected

     Each Fund may be subject to the following additional risks associated with
investing in non-U.S. issuers, which may involve unique risks compared to
investing in securities of U.S. issuers. These risks are more pronounced to the
extent the Funds invests in issuers in countries with emerging markets or if the
Funds invest significantly in one country. These risks may include:

     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, the adviser/subadviser might not be able to sell the
          Fund's portfolio securities at times, in amounts and at prices it
          considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     In addition, at times, more than 25% of Pioneer International Core Equity
Fund's assets may be invested in the same market segment, such as financial or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a Fund without the same focus.


                                       10


     AmSouth International Equity Fund is subject to risks relating to the fact
that it is non-diversified. The Fund may invest in a small number of companies
which may increase the volatility of the Fund. Accordingly, the Fund's portfolio
may be more sensitive to changes in the market value of a single company or
industry.

     AmSouth International Equity Fund may trade securities actively to achieve
its principal investment strategies. Active trading of portfolio securities
could increase the Fund's transaction costs (thereby lowering its performance)
and may increase the amount of taxes that you pay (on distributions of net gains
realized on those trades).

Past Performance

     Set forth below is performance information for AmSouth International Equity
Fund. The bar charts show how your AmSouth Fund's total return (not including
any deduction for sales charges) has varied from year to year for each full
calendar year. The tables show average annual total return (before and after
taxes) for your AmSouth Fund over time for each class of shares (including
deductions for sales charges) compared with a broad-based securities market
index. The bar charts give an indication of the risks of investing in your
AmSouth Fund, including the fact that you could incur a loss and experience
volatility of returns year to year. Past performance before and after taxes does
not indicate future results. Pioneer International Core Equity Fund has not
commenced investment operations.

(1)  The quoted returns reflect the performance from 8/15/97 to 12/13/98 of the
     DG International Equity Fund and from 12/14/98 to 3/12/00 of the ISG
     International Equity Fund, which were open-end investment companies that
     were the predecessor funds to the International Equity Fund. The
     predecessor funds were managed using substantially the same investment
     objective, policies and methodologies as the Fund. Class A shares were
     first offered on 8/15/97. Performance for the Class B shares, which were
     first offered on 2/2/99, is based on the historical performance of the
     Fund's Class A shares, including the performance of the predecessor funds,
     (without sales charge) prior to that date. The historical performance of
     the Class B shares has been restated to reflect the Fund's Class B
     distribution (12b-1) fees and the contingent deferred sales charge.

(2)  The quoted returns reflect the performance from 8/15/97 to 12/13/98 of the
     DG International Equity Fund and from 12/14/98 to 3/12/00 of the ISG
     International Equity Fund, which were open-end investment companies that
     were the predecessor funds to the International Equity Fund. The
     predecessor funds were managed using substantially the same investment
     objective, policies and methodologies as the Fund Performance for the Class
     I shares, which were first offered on 12/14/98, is based on the historical
     performance of the Fund's Class A shares, including the performance of the

(3)  The Morgan Stanley Capital International Europe, Australasia, Far East
     Index ("MSCI EAFE Index"), an unmanaged, capitalization weighted index of
     21 international markets, is for reference only, does not mirror the Fund's
     investments, and reflects no deduction for fees, expenses or taxes and was
     calculated from 7/31/97.

The above table shows the impact of taxes on the AmSouth International Equity
Fund's returns. After-tax returns are only shown for Class A shares and may vary
for Class B shares. The Fund's after-tax returns are calculated using the
highest individual federal marginal income tax rates and do not reflect the
impact of state and local taxes. In certain cases, the figure representing
"Return After Taxes on Distributions and Sale of Fund Shares" may be higher than
the other return figures for the same period. A higher after-tax return results
when a capital loss occurs upon redemption and translates into an assumed tax
deduction that benefits the shareholder. Please note that actual after-tax
returns depend on an investor's tax situation and may differ from those shown.
Also note that after-tax returns shown are not relevant to investors who hold
their Fund shares through tax-deferred arrangements, such as 401(k) plans or
individual retirement accounts.

     ISG Funds, the CDSC on such Class B shares held continuously declines over
     six years, starting with year one and ending in year seven from: 4%, 3%,
     3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
     declines over six years, starting with year one and ending in year seven
     from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in
     the case of shares acquired in the ISG combination), Class B shares
     automatically convert to Class A shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 30 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.

(5)  Other expenses for your AmSouth Fund are being limited to 0.41% for Class A
     shares, 0.41% for Class B shares and 0.26% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of Amsouth International Equity Fund. The Trustees considered the
following matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

     Third, the estimated pro forma expenses of the Pioneer Fund, after giving
effect to the Reorganization, on a gross basis are lower than your AmSouth
Fund's gross operating expenses. The Trustees recognized that the Pioneer Fund's
operating expenses net of expense limitations, and its management fee, are
higher than your Fund's expenses net of expense limitations and management fee
(except for Class I shares, for which pro forma expenses of the Pioneer Fund's
Class Y shares are estimated to be lower on both a gross and a net basis).
However, the expense limitations on your AmSouth Fund are voluntary and may be
discontinued at any time. In addition, the Trustees considered the positive
factors associated with the Reorganization to outweigh the negative factors,
such as the increase in expenses of the Pioneer Fund. The Trustees also
considered that the aggregate Rule 12b-1 distribution and shareholder servicing
fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class
B shares of each Fund are the same. Moreover, your AmSouth Fund's Class I shares
pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's
Class Y shares. In addition, the broader distribution arrangements of the
Pioneer Fund offer greater potential for further asset growth and reduced per
share expenses.


                                       14


     Fourth, the Class A, B and Y shares of Pioneer International Core Equity
Fund received in the Reorganization will provide AmSouth International Equity
Fund shareholders with exposure to substantially the same investment product as
they currently have.

     Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.


                                       15


     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-2, because it contains details
that are not in the summary.

     Each Fund has an investment objective of long-term capital growth and,
consequently, the Funds have similar investment polices and risks. In the table
below, if a row extends across the entire table, the policy disclosed applies to
both your AmSouth Fund and the Pioneer Fund.

                                  The fee will be charged on all covered
                                  redemptions and exchanges, including those
                                  made through retirement plan, brokerage and

                                  shares purchased upon the reinvestment of
                                  dividend and capital gain distributions.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    The market segment on which the Fund focuses - undervalued growth
          stocks - underperforms other kinds of investments or market averages

     o    Value stocks fall out of favor with investors

     o    The adviser's/subadviser's judgment about the attractiveness, growth
          potential or potential appreciation of a particular stock proves to be
          incorrect

     Each Fund is subject to risks relating to the fact that it is
non-diversified. Each Fund may invest in a small number of companies which may
increase the volatility of the Fund. Accordingly, each Fund's portfolio may be
more sensitive to changes in the market value of a single company or industry.

     Each Fund may trade securities actively to achieve its principal investment
strategies. Active trading of portfolio securities could increase the Fund's
transaction costs (thereby lowering its performance) and may increase the amount
of taxes that you pay (on distributions of net gains realized on those trades).
However, the adviser/subadviser expects that the Fund's annual portfolio
turnover rate will average less than 50% each year.

     If either Fund invests in securities with additional risk, that Fund's
share price volatility accordingly could be greater and its performance lower.

     At times, more than 25% of the Pioneer Focused Equity Fund's assets may be
invested in the same market segment, such as financials or technology. To the
extent the Fund emphasizes investments in a market segment, the Fund will be
subject to a greater degree to the risks particular to the industries in that
segment, and may experience greater market fluctuation, than a fund without the
same focus. For example, industries in the financial segment, such as banks,
insurance companies, broker-dealers and REITs, may be sensitive to changes in
interest rates and general economic activity and are subject to extensive
government regulation. Industries in the technology segment, such as information
technology, communications equipment, computer hardware and software, and office
and scientific equipment, are subject to risks of rapidly evolving technology,
short product lives, rates of corporate expenditures, falling prices and
profits, competition from new market entrants, and general economic conditions.


                                       9


     Pioneer Focused Equity Fund may be subject to the following additional
risks associated with investing in non-U.S. issuers, which may involve unique
risks compared to investing in securities of U.S. issuers. Some of these risks
do not apply to larger, more developed non-U.S. countries. However, these risks
are more pronounced for issuers of securities in emerging markets. These risks
may include:

     o    Less information about non-U.S. issuers or markets may be available
          due to less rigorous disclosure or accounting standards or regulatory
          practices

     o    Many non-U.S. markets are smaller, less liquid and more volatile. In a
          changing market, Pioneer may not be able to sell the Fund's portfolio
          securities at times, in amounts and at prices it considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     o    The economies of non-U.S. countries may grow at slower rates than
          expected or may experience a downturn or recession

     o    Economic, political and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

(1)  Class A shares were first offered on 9/1/98. Performance for the Class B
     shares, which were first offered on 9/2/98, is based on the historical
     performance of the Fund's Class A shares (without sales charge) prior to
     that date. The historical performance of the Class B shares has been
     restated to reflect the Fund's Class B shares distribution (12b-1) fees and
     the contingent deferred sales charge.

2    Performance for the Class I shares, which were first offered on 9/1/98, is
     based on the historical performance of the Fund's Class A shares (without
     sales charge) prior to that date.

(3)  The S&P 500 Index, a widely recognized, unmanaged index of 500 common
     stocks, is for reference only, does not mirror the Fund's investments, and
     reflects no deduction for fees, expenses or taxes.

The table above shows the impact of taxes on the Fund's returns. After-tax
returns are only shown for Class A shares and may vary for Class B shares. The
Fund's after-tax returns are calculated using the highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes. In certain cases, the figure representing "Return After Taxes on
Distributions and Sale of Fund Shares" may be higher than the other return
figures for the same period. A higher after-tax return results when a capital
loss occurs upon redemption and translates into an assumed tax deduction that
beneflts the shareholder. Please note that actual after-tax returns depend on an
investor's tax situation and may differ from those shown. Also note that
after-tax returns shown are not relevant to investors who hold their Fund shares
through tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  Sales charges may be reduced depending upon the amount invested or, in
     certain circumstances, waived. Class A shares of the Pioneer Fund bought as
     part of an investment of $1 million or more are not subject to an initial
     sales charge, but may be charged a CDSC of 1.00% if sold within one year of
     purchase.

(3)  A CDSC on Class B shares held continuously declines over six years starting
     with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight
     years after purchase Class B shares automatically convert to Class A
     shares.

(4)  To discourage short-term trading, a redemption fee of 2.00% will be charged
     on sales or exchanges of Class A, Class B and Class I shares of your
     AmSouth Fund made within 7 days of the date of purchase. A wire transfer
     fee of $7.00 will be deducted from the amount of your redemption if you
     request a wire transfer.


                                       12


(5)  Other expenses for your AmSouth Fund are being limited to 0.49% for Class A
     shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(6)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, and (e) the expense limitation for your Fund is in effect for
year one. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of Amsouth Select Equity Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, and AmSouth Bank
informed the Trustees that they did not intend to continue to provide investment
advisory services to the AmSouth Funds. Consequently, a change in your Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer


                                       13


family of mutual funds offers over 80 funds, including domestic and
international equity and fixed income funds and a money market fund that will be
available to your AmSouth Fund's shareholders through exchanges. In addition,
Pioneer offers shareholders additional options for their accounts, including the
ability to transact and exchange shares over the telephone or online and the
ability to access account values and transaction history in all of the
shareholder's direct accounts in the Pioneer Funds over the telephone or online.

     Third, Pioneer Focused Equity Fund's management fee (0.65% of average daily
net assets up to $1 billion, and 0.60% on assets greater than $1 billion) will
be substantially lower than the advisory fee of your AmSouth Fund (0.80% of
average daily net assets). The aggregate Rule 12b-1 distribution and shareholder
servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A
and Class B shares of both Funds will be the same. Moreover, your AmSouth Fund's
Class I shares pay a non 12b-1 shareholder servicing fee that will not be paid
by the Pioneer Fund's Class Y shares. On a pro forma basis, the estimated
expense ratio of each class of shares of the Pioneer Fund is estimated to be
lower than the expense ratio of the corresponding class of your AmSouth Fund. In
addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduced per share expenses.

     Fourth, the Class A, B and Y shares of Pioneer Focused Equity Fund received
in the Reorganization will provide AmSouth Select Equity Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                              The Fund uses a "first-in, first-out" method
                              to determine how long you have held your
                              shares. This means that if you purchased
                              shares on different days, the shares purchased

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

      o     The stock market goes down (this risk may be greater in the short
            term)

      o     The adviser's judgment about the attractiveness, growth potential or
            potential appreciation of a particular stock proves to be incorrect

      o     The market segment on which the Fund equity investment are focused -
            value and growth stocks - under performs other kinds of investments
            or market averages

      o     The value of the Fund's fixed-income investments declines due to an
            increase in interest rates (generally, an increase in the average
            maturity of the fixed income portfolio of the Fund will make it more
            sensitive to interest rate risk)

      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay principal earlier than scheduled,
            forcing the Fund to reinvest in lower yielding securities. This is
            known as call or prepayment risk

      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk

      o     An issuer cannot make timely interest and principal payments on its
            debt securities, such as bonds (the lower a security's rating, the
            greater its credit risk)

                                       10



      Each Fund may trade securities actively to achieve its principal
investment strategies. Active trading of portfolio securities could increase
each Fund's transaction costs (thereby lowering its performance) and may
increase the amount of taxes that you pay (on distributions of net gains
realized on those trades).

      If either Fund invests in securities with additional risk, that Fund's
share price volatility accordingly could be greater and its performance lower.

      At times, more than 25% of the Fund's assets may be invested in the same
market segment, such as financials or technology. To the extent the Fund
emphasizes investments in a market segment, the Fund will be subject to a
greater degree to the risks particular to the industries in that segment, and
may experience greater market fluctuation, than a Fund without the same focus.
For example, industries in the financial segment, such as banks, insurance
companies, broker-dealers and REITs, may be sensitive to changes in interest
rates and general economic activity and are subject to extensive government
regulation. Industries in the technology segment, such as information
technology, communications equipment, computer hardware and software, and office
and scientific equipment, are subject to risks of rapidly evolving technology,
short product lives, rates of corporate expenditures, falling prices and
profits, competition from new market entrants, and general economic conditions.

      If the Fund does a lot of trading, it may incur additional operating
expenses, which would reduce performance, and could cause shareowners to incur a
higher level of taxable income or capital gains.

      Pioneer Classic Balanced Fund may be subject to the following additional
risks associated with investing in non-U.S. issuers, which may involve unique
risks compared to investing in securities of U.S. issuers. Some of these risks
do not apply to larger, more developed non-U.S. countries. However, these risks
are more pronounced for issuers of securities in emerging markets. These risks
may include:

      o     Less information about non-U.S. issuers or markets may be available
            due to less rigorous disclosure or accounting standards or
            regulatory practices

      o     Many non-U.S. markets are smaller, less liquid and more volatile. In
            a changing market, Pioneer may not be able to sell the Fund's
            portfolio securities at times, in amounts and at prices it considers
            reasonable

      o     Adverse effect of currency exchange rates or controls on the value
            of the Fund's investments

      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession

      o     Economic, political and social developments may adversely affect the
            securities markets

      o     Withholding and other non-U.S. taxes may decrease the Fund's return

(1)   Class A shares were first offered on 12/19/91. Performance for the Class B
      shares, which were first offered on 9/2/97, is based on the historical
      performance of the Fund's Class A shares (without sales charge) prior to
      that date. The historical performance of the Class B shares has been
      restated to reflect the Fund's Class B shares distribution (12b-1) fees
      and the contingent deferred sales charge.

(2)   Performance for the Class I shares, which were first offered on 9/1/97, is
      based on the historical performance of the Fund's Class A shares (without
      sales charge) prior to that date.

      The table shows the impact of taxes on the Fund's returns. After-tax
      returns are only shown for Class A shares and may vary for Class B shares.
      The Fund's after-tax returns are calculated using the highest individual
      federal marginal income tax rates and do not reflect the impact of state
      and local taxes. In certain cases, the figure representing "Return After
      Taxes on Distributions and Sale of Fund Shares" may be higher than the
      other return figures for the same period. A higher after-tax return
      results when a capital loss occurs upon redemption and translates into an
      assumed tax deduction that benefits the shareholder. Please note that
      actual after-tax returns depend on an investor's tax situation and may
      differ from those shown. Also note that after-tax returns shown are not
      relevant to investors who hold their Fund shares through tax-deferred
      arrangements, such as 401(k) plans or individual retirement accounts.

      performance is attached as Exhibit C.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

                                       13



(3)   A CDCS on Class B shares held continuously declines over six years
      starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%,
      1%. Eight years after purchase Class B shares automatically convert to
      Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.53% for Class
      A shares, 0.53% for Class B shares and 0.38% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, and (e) the expense limitation for your Fund is in effect for
year one. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of Amsouth Balanced Fund. The Trustees considered the following
matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, and AmSouth Bank
informed the Trustees that they did not intend to continue to provide investment
advisory services to the AmSouth Funds. Consequently, a change in your Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate

                                       14



shareholders invested in reliance on AAMI's role to withdraw from the Fund,
thereby reducing fund size and increasing fund expense ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges. In addition, Pioneer offers shareholders additional options for their
accounts, including the ability to transact and exchange shares over the
telephone or online and the ability to access account values and transaction
history in all of the shareholder's direct accounts in the Pioneer Funds over
the telephone or online.

     Third, Pioneer Classic Balanced Fund's management fee (0.65% of average
daily net assets on the first $1 billion, 0.60% on the next $4 billion, and
0.55% on assets over $5 billion) will be substantially lower than the advisory
fee of your Fund (0.80% of average daily net assets). The aggregate Rule 12b-1
distribution and shareholder servicing fees and non-Rule 12b-1 shareholder
servicing fees paid by the Class A and Class B shares of both Funds will be the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that will not be paid by the Pioneer Fund's Class Y shares. On a
pro forma basis, both the gross and net expenses of each class of the Pioneer
Fund are estimated to be lower than the expenses of the corresponding class of
your AmSouth Fund. In addition, the broader distribution arrangements of the
Pioneer Fund offer greater potential for further asset growth and reduce per
share expenses.

      Fourth, the Class A, B and Y shares of Pioneer Classic Balanced Fund
received in the Reorganization will provide AmSouth Balanced Fund shareholders
with exposure to substantially the same investment product as they currently
have.

      Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

      Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganizations.

      The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

      The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                   Pioneer Ibbotson Aggressive Allocation Fund

                                  PROPOSAL 1(j)

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

      The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

      Each Fund is structured as a "fund of funds," which means all of its
assets are invested in other mutual funds ("underlying funds"). Your Fund
invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in
other Pioneer Funds but is seeking an exemptive order from the Securities and
Exchange Commission that would permit the Pioneer Fund to invest, in addition,
in mutual funds that are not managed by Pioneer. To the extent Pioneer receives
an order from the Securities and Exchange Commission that permits Pioneer to
invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund
intend to rely on such order, subject to any applicable conditions of the order.
In the table below, if a row extends across the entire table, the policy
disclosed applies to both your AmSouth Fund and the Pioneer Fund.

                              Normally, the Fund invests substantially all of its assets in underlying funds to meet its
                              investment objective. However, the Fund may invest a portion of its assets in cash, cash
                              equivalents or in money market funds. The underlying funds may also invest a portion of their
                              assets in money market funds, securities with remaining maturities of less than one year, cash
                              equivalents or may hold cash. For temporary defensive purposes, including during periods of
                              unusual cash flows, the Fund and each of the underlying funds may depart from its principal
                              investment strategies and invest part or all of its assets in these securities or may hold cash.
                              During such periods, the Fund may not be able to achieve its investment objective. The Fund
                              intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in which the
                              Fund normally invests have extraordinary risks due to political or economic factors and in other
                              extraordinary circumstances.

                              If you sell your shares or exchange them for
                              shares of another AmSouth fund within 7 days
                              of the date of purchase, you will be charged a
                              2.00% fee on the current net asset value of the
                              shares sold or exchanged. The fee is paid to the
                              Fund to offset the costs associated with short-
                              term trading, such as portfolio transaction and
                              administrative costs.

                              The Fund uses a "first-in, first-out" method to
                              determine how long you have held your shares.
                              This means that if you purchased shares on
                              different days, the shares purchased first will
                              be considered redeemed first for purposes of
                              determining whether the redemption fee will be
                              charged.

                              The fee will be charged on all covered
                              redemptions and exchanges, including those
                              made through retirement plan, brokerage and
                              other types of omnibus accounts (except where
                              it is not practical for the plan administrator or
                              brokerage firm to implement the fee). The Fund
                              will not impose the redemption fee on a
                              redemption or exchange of shares purchased

Comparison of Principal Risks of Investing in the Funds

            Because each Fund has a similar investment objective, primary
investment policies and strategies, the Funds are subject to the same principal
risks. You could lose money on an investment in a Fund or a Fund may not perform
as well as other investment options.

Fund of funds structure and layering of fees

                                       9



      Each Fund is structured as a fund of funds. Each Fund's investments are
focused in the underlying funds, so the Fund's investment performance is
directly related to the performance of the underlying funds. Each Fund's net
asset value will be affected by the performance of the equity and bond markets
and the value of the mutual funds in which the Fund invests. Since the Funds
mainly invest in the underlying funds, as opposed to other types of securities,
the Funds do not have the same flexibility in their portfolio holdings as many
mutual funds. In addition, each Fund indirectly pays a portion of the expenses
incurred by the underlying funds. Consequently, an investment in a Fund entails
more direct and indirect expenses than a direct investment in the underlying
funds. For instance, you will pay management fees and operating expenses of both
the Fund and the underlying funds.

      The underlying funds will not necessarily make consistent investment
decisions, which may also increase your costs. One underlying fund may buy the
same security that another underlying fund is selling. You would indirectly bear
the costs of both trades without achieving any investment purpose. These
transactions may also generate taxable gains. You may receive taxable gains from
portfolio transactions by the underlying funds as well as taxable gains from the
Fund's transactions in shares of the underlying funds.

      Currently, Pioneer manages all of the funds underlying the Pioneer Fund.
Because the portfolio management teams of each of the underlying Pioneer funds
may draw upon the resources of the same equity and fixed income analyst team or
may share common investment management styles or approaches, the underlying
funds may hold many common portfolio positions, reducing the diversification
benefits of an asset allocation style.

Equity investments

      Equity funds invest primarily in equity securities (such as stocks), which
are more volatile and carry more risks than some other forms of investment. When
the value of the stocks held by an underlying equity fund goes down, the value
of your investment in the Fund will be affected.

      The underlying equity funds have risks associated with investing in equity
securities. An equity fund could underperform other investments if:

      o     The stock market goes down (this risk may be greater in the short
            term)
      o     The fund's equity investments do not have the growth potential or
            value characteristics originally expected
      o     Stocks selected for income do not achieve the same return as
            securities selected for capital growth
      o     The types of stocks in which the fund invests or the fund's
            investment approach fall out of favor with investors

Fixed income investments

      Fixed income funds primarily invest in debt securities, such as government
securities, investment grade corporate securities, junk bonds, mortgaged backed
securities, asset-backed securities, and money market securities. The value of
your investment in the fund will change as the value of investments of the
underlying funds increases and decreases.

      The underlying fixed income funds have risks associated with investing in
debt securities. A fund could underperform other investments if:

      o     Interest rates go up causing the value of the fund's portfolio to
            decline
      o     The issuer of a debt security owned by the fund defaults on its
            obligation to pay principal or interest or has its credit rating
            downgraded
      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay earlier than scheduled, forcing
            the fund to reinvest in lower yielding securities. This is known as
            call or prepayment risk
      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk
      o     The investment manager's judgment about the attractiveness, relative
            value or potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

Equity securities of smaller companies

                                       10



      Compared to large companies, small and mid-sized companies, and the market
for their equity securities, are likely to:

      o     Be more sensitive to changes in the economy, earnings results and
            investor expectations
      o     Have more limited product lines and capital resources
      o     Experience sharper swings in market values
      o     Be harder to sell at the times and prices Pioneer thinks appropriate
      o     Offer greater potential for loss than other U.S. equity securities

Equity securities of real estate industry issuers

      Specific risks associated with the real estate industry include:

      o     The U.S. or a local real estate market declines due to adverse
            economic conditions, overbuilding and high vacancy rates, reduced or
            regulated rents or other causes
      o     Interest rates go up. Rising interest rates can adversely affect the
            availability and cost of financing for property acquisitions and
            other purposes and reduce the value of a REIT's fixed income
            investments
      o     The values of properties owned by a REIT or the prospects of other
            real estate industry issuers may be hurt by property tax increases,
            zoning changes, other governmental actions, environmental
            liabilities, natural disasters or increased operating expenses
      o     A REIT in an underlying fund's portfolio is, or is perceived by the
            market to be, poorly managed

Non-U.S. securities

      Investing in non-U.S. issuers, including emerging market issuers, may
involve unique risks compared to investing in securities of issuers in the U.S.
These risks are more pronounced to the extent the fund invests in issuers in the
lesser-developed emerging markets or in one region, such as Europe or the
Pacific Rim. These risks may include:

      o     Less information about the non-U.S. issuers or markets may be
            available due to less rigorous disclosure or accounting standards or
            regulatory practices
      o     Adverse effect of currency exchange rates or controls on the value
            of the fund's investments
      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession
      o     Economic, political and social developments may adversely affect
            securities markets
      o     Withholding and other non-U.S. taxes may decrease the fund's return

High yield/below investment grade debt securities

      Investment in high yield securities involves substantial risk of loss.
These securities are considered speculative with respect to the issuer's ability
to pay interest and principal and are susceptible to default or decline in
market value due to adverse economic and business developments. The market
values for high yield securities tend to be very volatile, and these securities
are less liquid than investment grade debt securities. For these reasons, your
investment in the fund is subject to the following specific risks:

      o     Increased price sensitivity to changing interest rates and
            deteriorating economic environment
      o     Greater risk of loss due to default or declining credit quality
      o     Adverse company specific events are more likely to render the issuer
            unable to make interest and/or principal payments
      o     A negative perception of the high yield market develops, depressing
            the price and liquidity of high yield securities. This negative
            perception could last for a significant period of time

Derivatives

      Certain underlying funds may use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts 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. The underlying funds may use
derivatives for a variety of purposes, including:

      o     As a hedge against adverse changes in stock market prices, interest
            rates or currency exchange rates
      o     As a substitute for purchasing or selling securities
      o     To increase the fund's return as a non-hedging strategy that may be
            considered speculative

                                       11



      Even a small investment in derivatives can have a significant impact on a
fund's exposure to stock market values, interest rates or currency exchange
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.

(1)   The S&P 500, an unmanaged index of 500 stocks, is for reference only, does
      not mirror the Fund's investments, and reflects no deduction for fees,
      expenses or taxes.

The table above shows the impact of taxes on AmSouth Strategic Portfolios:
Aggressive Growth Portfolio's returns. After-tax returns are only shown for
Class A shares and Class I shares and may vary for Class B shares. The Fund's
after-tax returns are calculated using the highest individual federal marginal
income tax rates and do not reflect the impact of state and local taxes. In
certain cases, the figure representing "Return After Taxes on Distributions and
Sale of Fund Shares" may be higher than the other return figures for the same
period. A higher after-tax return results when a capital loss occurs upon
redemption and translates into an assumed tax deduction that benefits the
shareholder. Please note that actual after-tax returns depend on an investor's
tax situation and may differ from those shown. Also note that after-tax returns
shown are not relevant to shareholders who hold Fund shares through tax-deferred
arrangements, such as 401(k) plans or individual retirement accounts.

The Funds' Fees and Expenses

      Shareholders of both Funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay if
you were to buy and hold shares of each Fund. The expenses in the tables
appearing below are based on (i) for the AmSouth Strategic Portfolios:
Aggressive Growth Portfolio, the expenses of AmSouth Strategic Portfolios:
Aggressive Growth Portfolio for the period ended January 31, 2005 and (ii) for
Pioneer Ibbotson Aggressive Allocation Fund, the estimated expenses for the
period ended January 31, 2005. Future expenses for all share classes may be
greater or less. The tables also show the pro forma expenses of the combined
Fund assuming the Reorganization occurred on January 31, 2005.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Approximately eight years after
      purchase (seven years in the case of shares acquired in the ISG
      combination), Class B shares automatically convert to Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.36% for Class
      A shares, 0.36% for Class B shares and 0.31% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time. Pioneer has contractually agreed not to impose
      all or a portion of its fees or to limit other direct ordinary operating
      expenses to the extent required to reduce expenses, other than "Estimated
      average expense ratio of underlying funds," to 0.85% of the average daily
      net assets attributable to Class A shares and 1.64% of average daily net
      assets attributable to Class B shares. This expense limitation is in
      effect for Class A shares until December 1, 2008 and in effect for Class B
      until December 1, 2006. There can be no assurance that Pioneer will extend
      these expense limitations past such dates. The expense limitation does not
      limit the expenses of the underlying funds indirectly incurred by a
      shareholder.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

(7)   Class Y shares of the Pioneer Fund are being offered for the first time in
      connection with the Reorganization.

The hypothetical example below helps you compare the cost of investing in each
Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods
shown, (b) you reinvest all dividends and distributions, (c) your investment has
a 5% return each year, and (d) each Fund's gross operating expenses remain the
same. The examples are for comparison purposes only and are not a representation
of either Fund's actual expenses or returns, either past or future.

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Strategic Portfolios: Aggressive Growth Portfolio. The
Trustees considered the following matters, among others, in approving the
proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your Fund's investment
adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $15.7 billion in fixed income securities. Pioneer is part of
the global asset management group of UniCredito Italiano S.p.A., one of the
largest banking groups in Italy, providing investment management and financial
services to mutual funds, institutional and other clients. As of December 31,
2004, assets under management of UniCredito Italiano S.p.A. were approximately
$175 billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

      Third, Pioneer Ibbotson Aggressive Allocation Fund's management fee (0.17%
of average daily net assets) is lower than the advisory fee of your Fund (0.20%
of average daily net assets). Both the historical and estimated pro forma
expenses of the Pioneer Fund, after giving effect to the Reorganization, on a
gross and net basis are lower than your Fund's gross and net operating expenses.
The aggregate Rule 12b-1 distribution and shareholder servicing fees and
non-Rule 12b-1 shareholder

                                       15



servicing fees paid by both the Class A and Class B shares of Funds are the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that is not paid by the Pioneer Fund's Class Y shares. In
addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduce per share expenses.

      Fourth, because of Pioneer distribution arrangements, Pioneer Fund has
greater potential to further increase the assets compared to your Fund. Further
assets growth is anticipated to further reduce the combined Fund's gross
operating expenses per share.

      Fifth, the Class A, B and Y shares of the Pioneer Fund received in the
Reorganization will provide AmSouth Fund shareholders with exposure to a similar
investment product as they currently have. The Trustees also noted that the
allocation decisions are made by Ibbotson, a leading asset allocation adviser,
and that the Pioneer Fund intends, as soon as permitted by the SEC, to include
unaffiliated mutual funds as underlying funds.

      Sixth, The transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

      Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth Fund in connection with the Reorganization.

      The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

      The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      The following table sets forth the capitalization of each Fund as of May

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

Information about the underlying funds

The following is intended to summarize the investment objectives and primary
strategies of, and to provide you with certain other information about, the
underlying funds. These summaries do not reflect all of the investment policies
and strategies that are disclosed in each underlying fund's prospectus, and are
not an offer of the underlying funds' shares. The underlying funds in which the
funds intend to invest may change from time to time and the funds may invest in
underlying funds in addition to those described below at the discretion of
Pioneer without prior notice to or approval of shareholders. The prospectus and
SAI for each underlying fund is available on the SEC's website as well as on our
website at www.pioneerfunds.com.

Each underlying fund normally will be invested according to its investment
strategy. However, an underlying fund also may have the ability to invest
without limitation in money market instruments or other investments for
temporary, defensive purposes.

The underlying funds that invest primarily in equity securities are:

The underlying funds that invest primarily in debt securities are:

Pioneer Bond Fund

Investment objective

To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the fund's portfolio.

Principal investment strategies

The fund invests primarily in:

      o     Debt securities issued or guaranteed by the U.S. government or its
            agencies and instrumentalities,

      o     Debt securities, including convertible debt, of corporate and other
            issuers rated at least investment grade at the time of investment,
            and comparably rated commercial paper,

                                       24



      o     Cash and cash equivalents, certificates of deposit, repurchase
            agreements maturing in one week or less and bankers' acceptances.

Normally, the fund invests at least 80% of its total assets in these securities.
In addition, the fund may invest up to 20% of its total assets in debt
securities rated below investment grade or, if unrated, of equivalent quality as
determined by Pioneer. Cash and cash equivalents include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from
the sale of the fund's portfolio investments.

Pioneer High Yield Fund

Investment objective

Maximize total return through a combination of income and capital appreciation.

Principal investment strategies

Normally, the fund invests at least 80% of its total assets in below investment
grade (high yield) debt securities and preferred stocks. These high yield
securities may be convertible into the equity securities of the issuer. Debt
securities rated below investment grade are commonly referred to as "junk bonds"
and are considered speculative. Below investment grade debt securities involve
greater risk of loss, are subject to greater price volatility and are less
liquid, especially during periods of economic uncertainty or change, than higher
rated debt securities.

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in debt securities. The fund has
the flexibility to invest in a broad range of issuers and segments of the debt
securities markets. Pioneer Investment Management, Inc., the fund's investment
adviser, allocates the fund's investments among the following three segments of
the debt markets:

      o     Below investment grade (high yield) securities of U.S. and non-U.S.
            issuers

      o     Investment grade securities of U.S. issuers

      o     Investment grade securities of non-U.S. issuers

Pioneer's allocations among these segments of the debt markets depend upon its
outlook for economic, interest rate and political trends. The fund invests
primarily in:

      o     Debt securities issued or guaranteed by the U.S. government, its
            agencies or instrumentalities or non-U.S. governmental entities

                                       26



      o     Debt securities of U.S. and non-U.S. corporate issuers, including
            convertible debt

      o     Mortgage-backed and asset-backed securities

The fund's investments may have fixed or variable principal payments and all
types of interest rate payment and reset terms, including fixed rate, adjustable
rate, zero coupon, contingent, deferred, payment in kind and auction rate
features. The fund invests in securities with a broad range of maturities.

Depending upon Pioneer's allocation among market segments, up to 70% of the
fund's total assets may be in debt securities rated below investment grade at
the time of purchase or determined to be of equivalent quality by Pioneer. Up to
20% of the fund's total assets may be invested in debt securities rated below
CCC by Standard & Poor's Ratings Group or the equivalent by another nationally
recognized statistical rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities.

As with all fixed income securities, the market values of convertible debt
securities tend to decline as interest rates increase and, conversely, to
increase as interest rates decline. However, when the market price of the common
stock underlying a convertible security exceeds the conversion price, the
convertible security tends to reflect the market price of the underlying common
stock.

Depending upon Pioneer's allocation among market segments, up to 85% of the
fund's total assets may be in debt securities of non-U.S. corporate and
governmental issuers, including debt securities of corporate and governmental
issuers in emerging markets.

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

      The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

      Each Fund is structured as a "fund of funds," which means all of its
assets are invested in other mutual funds ("underlying funds"). Your Fund
invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in
other Pioneer Funds but is seeking an exemptive order from the Securities and
Exchange Commission that would permit the Pioneer Fund to invest, in addition,
in mutual funds that are not managed by Pioneer. To the extent Pioneer receives
an order from the Securities and Exchange Commission that permits Pioneer to
invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund
intend to rely on such order, subject to any applicable conditions of the order.
In the table below, if a row extends across the entire table, the policy
disclosed applies to both your AmSouth Fund and the Pioneer Fund.

                             Pioneer Ibbotson Growth Allocation Fund:

                             Because this is a moderate growth allocation fund, Pioneer Ibbotson Growth Allocation Fund's assets
                             will be invested in equity and bond funds, although a small portion of its assets will be invested in
                             cash, cash equivalents, or in money market funds. Under normal circumstances, Pioneer Ibbotson Growth
                             Allocation Fund initially expects to invest its assets among asset classes in the following ranges:

                             Short-Term
                             Investments  Equity Fund  Fixed Income Fund

                             Based upon the analysis described under "Asset allocation process," the Fund initially expects to
                             invest its assets in underlying mutual funds within the following ranges:

                                                                               Percentage of

                             The Pioneer Fund may change its target allocation to each asset class, the underlying fund in
                             each asset class (including adding or deleting funds) or target allocations to each underlying
                             fund without prior approval from or notice to shareholders. Certain of the Pioneer Funds into
                             which the AmSouth Funds are being reorganized are not currently included in the above list of
                             funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such
                             additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which
                             your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those
                             additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced.

                             Appendix A contains a summary description of each of the underlying Pioneer funds.

                             Normally, the Fund invests substantially all of its assets in underlying funds to meet its
                             investment objective. However, the Fund may invest a portion of its assets in cash, cash
                             equivalents or in money market funds. The underlying funds may also invest a portion of their
                             assets in money market funds, securities with remaining maturities of less than one year, cash
                             equivalents or may hold cash. For temporary defensive purposes, including during periods of
                             unusual cash flows, the Fund and each of the underlying funds may depart from its principal
                             investment strategies and invest part or all of its assets in these securities or may hold
                             cash. During such periods, the Fund may not be able to achieve its investment objective. The
                             Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in
                             which the Fund normally invests have extraordinary risks due to political or economic factors
                             and in other extraordinary circumstances.

                             are currently charged for exchanges.

                             If you sell your shares or exchange them for
                             shares of another AmSouth fund within 7 days
                             of the date of purchase, you will be charged a
                             2.00% fee on the current net asset value of
                             the shares sold or exchanged. The fee is paid
                             to the Fund to offset the costs associated
                             with short-term trading, such as portfolio
                             transaction and administrative costs.

                             The Fund uses a "first-in, first-out" method
                             to determine how long you have held your
                             shares. This means that if you purchased
                             shares on different days, the shares purchased
                             first will be considered redeemed first for
                             purposes of determining whether the redemption
                             fee will be charged.

                             The fee will be charged on all covered
                             redemptions and exchanges, including those
                             made through retirement plan, brokerage and
                             other types of omnibus accounts (except where
                             it is not practical for the plan administrator
                             or brokerage firm to implement the fee). The
                             Fund will not impose the redemption fee on a
                             redemption or exchange of shares purchased
                             upon the reinvestment of dividend and capital

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on an investment in a fund or a fund may not perform as well as
other investment options.

Fund of funds structure and layering of fees

                                        9



      Each Fund is structured as a fund of funds. Each Fund's investments are
focused in the underlying funds, so the Fund's investment performance is
directly related to the performance of the underlying funds. Each Fund's net
asset value will be affected by the performance of the equity and bond markets
and the value of the mutual funds in which the Fund invests. Since the Funds
mainly invest in the underlying funds, as opposed to other types of securities,
the Funds do not have the same flexibility in their portfolio holdings as many
mutual funds. In addition, each Fund indirectly pays a portion of the expenses
incurred by the underlying funds. Consequently, an investment in a Fund entails
more direct and indirect expenses than a direct investment in the underlying
funds. For instance, you will pay management fees and operating expenses of both
the Fund and the underlying funds.

      The underlying funds will not necessarily make consistent investment
decisions, which may also increase your costs. One underlying fund may buy the
same security that another underlying fund is selling. You would indirectly bear
the costs of both trades without achieving any investment purpose. These
transactions may also generate taxable gains. You may receive taxable gains from
portfolio transactions by the underlying funds as well as taxable gains from the
fund's transactions in shares of the underlying funds.

      Currently, Pioneer manages all of the funds underlying the Pioneer Fund.
Because the portfolio management teams of each of the underlying Pioneer funds
may draw upon the resources of the same equity and fixed income analyst team or
may share common investment management styles or approaches, the underlying
funds may hold many common portfolio positions, reducing the diversification
benefits of an asset allocation style.

Equity investments

      Equity funds invest primarily in equity securities (such as stocks), which
are more volatile and carry more risks than some other forms of investment. When
the value of the stocks held by an underlying equity fund goes down, the value
of your investment in the fund will be affected.

      The underlying equity funds have risks associated with investing in equity
securities. An equity fund could underperform other investments if:

      o     The stock market goes down (this risk may be greater in the short
            term)
      o     The fund's equity investments do not have the growth potential or
            value characteristics originally expected
      o     Stocks selected for income do not achieve the same return as
            securities selected for capital growth
      o     The types of stocks in which the fund invests or the fund's
            investment approach fall out of favor with investors

Fixed income investments

      Fixed income funds primarily invest in debt securities, such as government
securities, investment grade corporate securities, junk bonds, mortgaged backed
securities, asset-backed securities, and money market securities. The value of
your investment in the fund will change as the value of investments of the
underlying funds increases and decreases.

      The underlying fixed income funds have risks associated with investing in
debt securities. A fund could underperform other investments if:

      o     Interest rates go up causing the value of the fund's portfolio to
            decline
      o     The issuer of a debt security owned by the fund defaults on its
            obligation to pay principal or interest or has its credit rating
            downgraded
      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay earlier than scheduled, forcing
            the fund to reinvest in lower yielding securities. This is known as
            call or prepayment risk
      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk
      o     The investment manager's judgment about the attractiveness, relative
            value or potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

Equity securities of smaller companies

      Compared to large companies, small and mid-sized companies, and the market
for their equity securities, are likely to:

                                       10



      o     Be more sensitive to changes in the economy, earnings results and
            investor expectations
      o     Have more limited product lines and capital resources
      o     Experience sharper swings in market values
      o     Be harder to sell at the times and prices Pioneer thinks appropriate
      o     Offer greater potential for loss than other U.S. equity securities

Equity securities of real estate industry issuers

      Specific risks associated with the real estate industry include:

      o     The U.S. or a local real estate market declines due to adverse
            economic conditions, overbuilding and high vacancy rates, reduced or
            regulated rents or other causes
      o     Interest rates go up. Rising interest rates can adversely affect the
            availability and cost of financing for property acquisitions and
            other purposes and reduce the value of a REIT's fixed income
            investments
      o     The values of properties owned by a REIT or the prospects of other
            real estate industry issuers may be hurt by property tax increases,
            zoning changes, other governmental actions, environmental
            liabilities, natural disasters or increased operating expenses
      o     A REIT in an underlying fund's portfolio is, or is perceived by the
            market to be, poorly managed

Non-U.S. securities

      Investing in non-U.S. issuers, including emerging market issuers, may
involve unique risks compared to investing in securities of issuers in the U.S.
These risks are more pronounced to the extent the fund invests in issuers in the
lesser-developed emerging markets or in one region, such as Europe or the
Pacific Rim. These risks may include:

      o     Less information about the non-U.S. issuers or markets may be
            available due to less rigorous disclosure or accounting standards or
            regulatory practices
      o     Adverse effect of currency exchange rates or controls on the value
            of the Fund's investments
      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession
      o     Economic, political and social developments may adversely affect
            securities markets
      o     Withholding and other non-U.S. taxes may decrease the Fund's return

High yield/below investment grade debt securities

      Investment in high yield securities involves substantial risk of loss.
These securities are considered speculative with respect to the issuer's ability
to pay interest and principal and are susceptible to default or decline in
market value due to adverse economic and business developments. The market
values for high yield securities tend to be very volatile, and these securities
are less liquid than investment grade debt securities. For these reasons, your
investment in the fund is subject to the following specific risks:

      o     Increased price sensitivity to changing interest rates and
            deteriorating economic environment
      o     Greater risk of loss due to default or declining credit quality
      o     Adverse company specific events are more likely to render the issuer
            unable to make interest and/or principal payments
      o     A negative perception of the high yield market develops, depressing
            the price and liquidity of high yield securities. This negative
            perception could last for a significant period of time

Derivatives

      Certain underlying funds may use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts 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. The underlying funds may use
derivatives for a variety of purposes, including:

      o     As a hedge against adverse changes in stock market prices, interest
            rates or currency exchange rates
      o     As a substitute for purchasing or selling securities
      o     To increase the fund's return as a non-hedging strategy that may be
            considered speculative

      Even a small investment in derivatives can have a significant impact on a
fund's exposure to stock market values, interest rates or currency exchange
rates. If changes in a derivative's value do not correspond to changes in the
value of the

                                       11



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.

Past Performance

      Set forth below is performance information for AmSouth Strategic
Portfolios: Growth Portfolio. The bar charts show how AmSouth Strategic
Portfolios: Growth Portfolio's total return (not including any deduction for
sales charges) has varied from year to year for each full calendar year. The
table shows average annual total return (before and after taxes) for each Fund
over time for each class of shares (including deductions for sales charges)
compared with a broad-based securities market index. The bar chart gives an
indication of the risks of investing in each Fund, including the fact that you
could incur a loss and experience volatility of returns year to year. Past
performance before and after taxes does not indicate future results.

(1)   The S&P 500, an unmanaged index of 500 stocks, is for reference only; it

The table above shows the impact of taxes on AmSouth Strategic Portfolios:
Growth Portfolio's returns. After-tax returns are only shown for Class A shares
and Class I shares and may vary for Class B shares. The Fund's after-tax returns
are calculated using the highest individual federal marginal income tax rates
and do not reflect the impact of state and local taxes. In certain cases, the
figure representing "Return After Taxes on Distributions and Sale of Fund
Shares" may be higher than the other return figures for the same period. A
higher after-tax return results when a capital loss occurs upon redemption and
translates into an assumed tax deduction that benefits the shareholder. Please
note that actual after-tax returns depend on an investor's tax situation and may
differ from those shown. Also note that after-tax returns shown are not relevant
to shareholders who hold Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts.

The Funds' Fees and Expenses

      Shareholders of both Funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay if
you were to buy and hold shares of each Fund. The expenses in the tables
appearing below are based on (i) for the AmSouth Strategic Portfolios: Growth
Portfolio, the expenses of AmSouth Strategic Portfolios: Growth Portfolio for
the period ended January 31, 2005 and (ii) for Pioneer Ibbotson Growth
Allocation Fund, the estimated expenses for the period ended January 31, 2005.
Future expenses for all share classes may be greater or less. The tables also
show the pro forma expenses of the combined Fund assuming the Reorganization
occurred on January 31, 2005.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.31% for Class
      A shares, 0.30% for Class B shares and 0.26% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time. Pioneer has contractually agreed not to impose
      all or a portion of its fees or to limit other direct ordinary operating
      expenses to the extent required to reduce expenses, other than "Estimated
      average expense ratio of underlying funds," to 0.79% of the average daily
      net assets attributable to Class A shares and 1.57% of average daily net
      assets attributable to Class B shares. This expense limitation is in
      effect for Class A shares until December 1, 2008 and in effect for Class B
      until December 1, 2006. There can be no assurance that Pioneer will

                                       14



      extend these expense limitations past such dates. The expense limitation
      does not limit the expenses of the underlying funds indirectly incurred by
      a shareholder.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

(7)   Class Y shares of the Pioneer Fund are being offered for the first time in
      connection with the Reorganization.

The hypothetical example below helps you compare the cost of investing in each
Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods
shown, (b) you reinvest all dividends and distributions, (c) your investment has
a 5% return each year, and (d) each Fund's gross operating expenses remain the
same. The examples are for comparison purposes only and are not a representation
of either Fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Strategic Portfolios: Growth Portfolio. The Trustees
considered the following matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your Fund's investment
adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $15.7 billion in fixed income securities. Pioneer is part of
the global asset management group of UniCredito Italiano S.p.A., one of the
largest banking groups in Italy, providing investment management and financial
services to mutual funds, institutional and other clients. As of December 31,
2004, assets under management of UniCredito Italiano S.p.A. were approximately
$175 billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international

                                       15



equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

     Third, Pioneer Ibbotson Growth Allocation Fund's management fee (0.17% of
average daily net assets) is lower than the advisory fee of your Fund (0.20% of
average daily net assets). Both the historical and estimated pro forma expenses
of the Pioneer Fund, after giving effect to the Reorganization, on a gross and
net basis are lower than your Fund's gross and net operating expenses. The
aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule
12b-1 shareholder servicing fees paid by the Class A and Class B shares of both
Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1
shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares.

     Fourth, because of Pioneer distribution arrangements, Pioneer Fund has
greater potential to further increase the assets compared to your fund. Further
assets growth is anticipated to further reduce the combined Fund's gross
operating expenses per share.

     Fifth, the Class A, B and Y shares of the Pioneer Fund received in the
Reorganization will provide AmSouth Fund shareholders with exposure to a similar
investment product as they currently have. The Trustees also noted that the
allocation decisions are made by Ibbotson, a leading asset allocation adviser,
and that the Pioneer Fund intends, as soon as permitted by the SEC, to include
unaffiliated mutual funds as underlying funds.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth Fund in connection with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

The following is intended to summarize the investment objectives and primary
strategies of, and to provide you with certain other information about, the
underlying funds. These summaries do not reflect all of the investment policies
and strategies that are disclosed in each underlying fund's prospectus, and are
not an offer of the underlying funds' shares. The underlying funds in which the
funds intend to invest may change from time to time and the funds may invest in
underlying funds in addition to those described below at the discretion of
Pioneer without prior notice to or approval of shareholders. The prospectus and
SAI for each underlying fund is available on the SEC's website as well as on our
website at www.pioneerfunds.com.

Each underlying fund normally will be invested according to its investment
strategy. However, an underlying fund also may have the ability to invest
without limitation in money market instruments or other investments for
temporary, defensive purposes.

The underlying funds that invest primarily in equity securities are:

The underlying funds that invest primarily in debt securities are:

Pioneer Bond Fund

Investment objective

To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the fund's portfolio.

Principal investment strategies

The fund invests primarily in:

      o     Debt securities issued or guaranteed by the U.S. government or its
            agencies and instrumentalities,

      o     Debt securities, including convertible debt, of corporate and other
            issuers rated at least investment grade at the time of investment,
            and comparably rated commercial paper,

                                       24



      o     Cash and cash equivalents, certificates of deposit, repurchase
            agreements maturing in one week or less and bankers' acceptances.

Normally, the fund invests at least 80% of its total assets in these securities.
In addition, the fund may invest up to 20% of its total assets in debt
securities rated below investment grade or, if unrated, of equivalent quality as
determined by Pioneer. Cash and cash equivalents include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from
the sale of the fund's portfolio investments.

Pioneer High Yield Fund

Investment objective

Maximize total return through a combination of income and capital appreciation.

Principal investment strategies

Normally, the fund invests at least 80% of its total assets in below investment
grade (high yield) debt securities and preferred stocks. These high yield
securities may be convertible into the equity securities of the issuer. Debt
securities rated below investment grade are commonly referred to as "junk bonds"
and are considered speculative. Below investment grade debt securities involve
greater risk of loss, are subject to greater price volatility and are less
liquid, especially during periods of economic uncertainty or change, than higher
rated debt securities.

            agencies or instrumentalities

equivalents. Cash and cash equivalents may include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from

Pioneer Strategic Income Fund

Investment objective

A high level of current income.

Principal investment strategies

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in debt securities. The fund has
the flexibility to invest in a broad range of issuers and segments of the debt
securities markets. Pioneer Investment Management, Inc., the fund's investment
adviser, allocates the fund's investments among the following three segments of
the debt markets:

      o     Below investment grade (high yield) securities of U.S. and non-U.S.
            issuers

      o     Investment grade securities of U.S. issuers

      o     Investment grade securities of non-U.S. issuers

Pioneer's allocations among these segments of the debt markets depend upon its
outlook for economic, interest rate and political trends. The fund invests
primarily in:

      o     Debt securities issued or guaranteed by the U.S. government, its
            agencies or instrumentalities or non-U.S. governmental entities

                                       26



      o     Debt securities of U.S. and non-U.S. corporate issuers, including
            convertible debt

      o     Mortgage-backed and asset-backed securities

The fund's investments may have fixed or variable principal payments and all
types of interest rate payment and reset terms, including fixed rate, adjustable
rate, zero coupon, contingent, deferred, payment in kind and auction rate
features. The fund invests in securities with a broad range of maturities.

Depending upon Pioneer's allocation among market segments, up to 70% of the
fund's total assets may be in debt securities rated below investment grade at
the time of purchase or determined to be of equivalent quality by Pioneer. Up to
20% of the fund's total assets may be invested in debt securities rated below
CCC by Standard & Poor's Ratings Group or the equivalent by another nationally
recognized statistical rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities.

As with all fixed income securities, the market values of convertible debt
securities tend to decline as interest rates increase and, conversely, to
increase as interest rates decline. However, when the market price of the common
stock underlying a convertible security exceeds the conversion price, the
convertible security tends to reflect the market price of the underlying common
stock.

Depending upon Pioneer's allocation among market segments, up to 85% of the
fund's total assets may be in debt securities of non-U.S. corporate and
governmental issuers, including debt securities of corporate and governmental
issuers in emerging markets.

                                  PROPOSAL 1(l)

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

      The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

      Each Fund is structured as a "fund of funds," which means all of its
assets are invested in other mutual funds ("underlying funds"). Your Fund
invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in
other Pioneer Funds but is seeking an exemptive order from the Securities and
Exchange Commission that would permit the Pioneer Fund to invest, in addition,
in mutual funds that are not managed by Pioneer. To the extent Pioneer receives
an order from the Securities and Exchange Commission that permits Pioneer to
invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund
intend to rely on such order, subject to any applicable conditions of the order.
In the table below, if a row extends across the entire table, the policy
disclosed applies to both your AmSouth Fund and the Pioneer Fund.

                             Pioneer Ibbotson Moderate Allocation Fund:

                             Because this is a moderate allocation fund, Pioneer Ibbotson Moderate Allocation Fund's assets
                             will be invested in equity and bond funds, although a portion of its assets will be invested in
                             cash, cash equivalents, or in money market funds. Under normal circumstances, Pioneer Ibbotson
                             Moderate Allocation Fund initially expects to invest its assets among asset classes in the
                             following ranges:

                             Short-Term

                             Based upon the analysis described under "Asset allocation process," the Fund initially expects
                             to invest its assets in underlying mutual funds within the following ranges:

                                                                                                            Percentage of

                             each asset class (including adding or deleting funds) or target allocations to each underlying

                             funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such
                             additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which
                             your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those
                             additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced.

                             Appendix A contains a summary description of each of the underlying Pioneer funds.

                             Normally, the Fund invests substantially all of its assets in underlying funds to meet its
                             investment objective. However, the Fund may invest a portion of its assets in cash, cash
                             equivalents or in money market funds. The underlying funds may also invest a portion of their
                             assets in money market funds, securities with remaining maturities of less than one year, cash
                             equivalents or may hold cash. For temporary defensive purposes, including during periods of
                             unusual cash flows, the Fund and each of the underlying funds may depart from its principal
                             investment strategies and invest part or all of its assets in these securities or may hold
                             cash. During such periods, the fund may not be able to achieve its investment objective. The
                             Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in
                             which the fund normally invests have extraordinary risks due to political or economic factors
                             and in other extraordinary circumstances.

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on an investment in a fund or a fund may not perform as well as
other investment options.

Fund of funds structure and layering of fees

      Each Fund is structured as a fund of funds. Each Fund's investments are
focused in the underlying funds, so the Fund's investment performance is
directly related to the performance of the underlying funds. Each Fund's net
asset value will be affected by the performance of the equity and bond markets
and the value of the mutual funds in which the fund invests. Since the Funds
mainly invest in the underlying funds, as opposed to other types of securities,
the Funds do not have the same flexibility in their portfolio holdings as many
mutual funds. In addition, each Fund indirectly pays a portion of the expenses
incurred by the underlying funds. Consequently, an investment in a Fund entails
more direct and indirect expenses than a direct investment in the underlying
funds. For instance, you will pay management fees and operating expenses of both
the Fund and the underlying funds.

      The underlying funds will not necessarily make consistent investment
decisions, which may also increase your costs. One underlying fund may buy the
same security that another underlying fund is selling. You would indirectly bear
the costs of both trades without achieving any investment purpose. These
transactions may also generate taxable gains. You may receive taxable gains from
portfolio transactions by the underlying funds as well as taxable gains from the
fund's transactions in shares of the underlying funds.

      Currently, Pioneer manages all of the funds underlying the Pioneer Fund.
Because the portfolio management teams of each of the underlying Pioneer funds
may draw upon the resources of the same equity and fixed income analyst team or
may share common investment management styles or approaches, the underlying
funds may hold many common portfolio positions, reducing the diversification
benefits of an asset allocation style.

Equity investments

      Equity funds invest primarily in equity securities (such as stocks), which
are more volatile and carry more risks than some other forms of investment. When
the value of the stocks held by an underlying equity fund goes down, the value
of your investment in the fund will be affected.

      The underlying equity funds have risks associated with investing in equity
securities. An equity fund could underperform other investments if:

      o     The stock market goes down (this risk may be greater in the short
            term)
      o     The fund's equity investments do not have the growth potential or
            value characteristics originally expected
      o     Stocks selected for income do not achieve the same return as
            securities selected for capital growth
      o     The types of stocks in which the fund invests or the fund's
            investment approach fall out of favor with investors

Fixed income investments

      Fixed income funds primarily invest in debt securities, such as government
securities, investment grade corporate securities, junk bonds, mortgaged backed
securities, asset-backed securities, and money market securities. The value of
your investment in the fund will change as the value of investments of the
underlying funds increases and decreases.

      The underlying fixed income funds have risks associated with investing in
debt securities. A fund could underperform other investments if:

      o     Interest rates go up causing the value of the fund's portfolio to
            decline
      o     The issuer of a debt security owned by the fund defaults on its
            obligation to pay principal or interest or has its credit rating
            downgraded
      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay earlier than scheduled, forcing
            the fund to reinvest in lower yielding securities. This is known as
            call or prepayment risk

                                       10



      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk
      o     The investment manager's judgment about the attractiveness, relative
            value or potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

Equity securities of smaller companies

      Compared to large companies, small and mid-sized companies, and the market
for their equity securities, are likely to:

      o     Be more sensitive to changes in the economy, earnings results and
            investor expectations
      o     Have more limited product lines and capital resources
      o     Experience sharper swings in market values
      o     Be harder to sell at the times and prices Pioneer thinks appropriate
      o     Offer greater potential for loss than other U.S. equity securities

Equity securities of real estate industry issuers

      Specific risks associated with the real estate industry include:

      o     The U.S. or a local real estate market declines due to adverse
            economic conditions, overbuilding and high vacancy rates, reduced or
            regulated rents or other causes
      o     Interest rates go up. Rising interest rates can adversely affect the
            availability and cost of financing for property acquisitions and
            other purposes and reduce the value of a REIT's fixed income
            investments
      o     The values of properties owned by a REIT or the prospects of other
            real estate industry issuers may be hurt by property tax increases,
            zoning changes, other governmental actions, environmental
            liabilities, natural disasters or increased operating expenses
      o     A REIT in an underlying fund's portfolio is, or is perceived by the
            market to be, poorly managed

Non-U.S. securities

      Investing in non-U.S. issuers, including emerging market issuers, may
involve unique risks compared to investing in securities of issuers in the U.S.
These risks are more pronounced to the extent the fund invests in issuers in the
lesser-developed emerging markets or in one region, such as Europe or the
Pacific Rim. These risks may include:

      o     Less information about the non-U.S. issuers or markets may be
            available due to less rigorous disclosure or accounting standards or
            regulatory practices
      o     Adverse effect of currency exchange rates or controls on the value
            of the fund's investments
      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession
      o     Economic, political and social developments may adversely affect
            securities markets
      o     Withholding and other non-U.S. taxes may decrease the fund's return

High yield/below investment grade debt securities

      Investment in high yield securities involves substantial risk of loss.
These securities are considered speculative with respect to the issuer's ability
to pay interest and principal and are susceptible to default or decline in
market value due to adverse economic and business developments. The market
values for high yield securities tend to be very volatile, and these securities
are less liquid than investment grade debt securities. For these reasons, your
investment in the fund is subject to the following specific risks:

      o     Increased price sensitivity to changing interest rates and
            deteriorating economic environment
      o     Greater risk of loss due to default or declining credit quality
      o     Adverse company specific events are more likely to render the issuer
            unable to make interest and/or principal payments
      o     A negative perception of the high yield market develops, depressing
            the price and liquidity of high yield securities. This negative
            perception could last for a significant period of time

                                       11



Derivatives

      Certain underlying funds may use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts 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. The underlying funds may use
derivatives for a variety of purposes, including:

      o     As a hedge against adverse changes in stock market prices, interest
            rates or currency exchange rates
      o     As a substitute for purchasing or selling securities
      o     To increase the fund's return as a non-hedging strategy that may be
            considered speculative

Even a small investment in derivatives can have a significant impact on a fund's
exposure to stock market values, interest rates or currency exchange 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.

The table above shows the impact of taxes on AmSouth Strategic Portfolios:
Growth & Income Portfolio's returns. After-tax returns are only shown for Class
A shares and Class I shares and may vary for Class B shares. The Fund's
after-tax returns are calculated using the highest individual federal marginal
income tax rates and do not reflect the impact of state and local taxes. In
certain cases, the figure representing "Return After Taxes on Distributions and
Sale of Fund Shares" may be higher than the other return figures for the same
period. A higher after-tax return results when a capital loss occurs upon
redemption and translates into an assumed tax deduction that benefits the
shareholder. Please note that actual after-tax returns depend on an investor's
tax situation and may differ from those shown. Also note that after-tax returns
shown are not relevant to shareholders who hold Fund shares through tax-deferred
arrangements, such as 401(k) plans or individual retirement accounts.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A Shares bought as part of an
      investment of $1 million or more are not subject to an initial sales
      charge, but may be charged a CDSC of 1.00% if sold within one year of
      purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B Shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares.

                                       15



(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.32% for Class
      A shares, 0.31% for Class B shares and 0.27% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time. Pioneer has contractually agreed not to impose
      all or a portion of its fees or to limit other direct ordinary operating
      expenses to the extent required to reduce expenses, other than "Estimated
      average expense ratio of underlying funds," to 0.74% of the average daily
      net assets attributable to Class A shares and 1.64% of average daily net
      assets attributable to Class B shares. This expense limitation is in
      effect for Class A shares until December 1, 2008 and in effect for Class B
      until December 1, 2006. There can be no assurance that Pioneer will extend
      these expense limitations past such dates. The expense limitation does not
      limit the expenses of the underlying funds indirectly incurred by a
      shareholder.

(6)   The management fee payable by the Pioneer Fund is equal to 0.13% of
      average daily net assets attributable to the Pioneer Fund's investments in
      underlying funds managed by Pioneer and cash and 0.17% of average daily
      net assets attributable to other investments, including underlying funds
      that are not managed by Pioneer, with breakpoints at incremental asset
      levels. Since initially all of the underlying funds are managed by
      Pioneer, the management fee will initially be 0.13% of average daily net
      assets.

(7)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

(8)   Class Y shares of the Pioneer Fund are being offered for the first time in
      connection with the Reorganization.

The hypothetical example below helps you compare the cost of investing in each
Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods
shown, (b) you reinvest all dividends and distributions, (c) your investment has
a 5% return each year, and (d) each Fund's gross operating expenses remain the
same. The examples are for comparison purposes only and are not a representation
of either Fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Strategic Portfolios: Growth & Income Portfolio. The
Trustees considered the following matters, among others, in approving the
proposal.

      First, AAMI, the investment adviser to your Amsouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your Fund's investment
adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

      Third, Pioneer Ibbotson Moderate Allocation Fund's management fee (0.17%
of average daily net assets) is lower than the advisory fee of your Fund (0.20%
of average daily net assets). Both the historical and estimated pro forma
expenses of the Pioneer Fund, after giving effect to the Reorganization, on a
gross and net basis are lower than your Fund's gross and net

                                       17



operating expenses. The aggregate Rule 12b-1 distribution and shareholder
servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A
and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's
Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the
Pioneer Fund's Class Y shares.

     Fourth, because of Pioneer distribution arrangements, Pioneer Fund has
greater potential to further increase the assets compared to your Fund. Further
assets growth is anticipated to further reduce the combined Fund's gross
operating expenses per share.

     Fifth, the Class A, B and Y shares of the Pioneer Fund received in the
Reorganization will provide AmSouth Fund shareholders with exposure to a similar
investment product as they currently have. The Trustees also noted that the
allocation decisions are made by Ibbotson, a leading asset allocation adviser,
and that the Pioneer Fund intends, as soon as permitted by the Securities and
Exchange Commission, to include unaffiliated mutual funds as underlying funds.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares. Although
the Reorganization will result in a per share decrease in capital loss
carryforwards, the potential negative tax consequences of this aspect of the
Reorganization are outweighed by the advantages of the Reorganization. The
Reorganization will also result in a per share decrease in net unrealized
capital gains.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth Fund in connection with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also
sets forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth Strategic Portfolios: Moderate Growth &
Income Portfolio approve the reorganization of their fund into Pioneer Ibbotson
Moderate Allocation Fund.

Information about the underlying funds

The following is intended to summarize the investment objectives and primary
strategies of, and to provide you with certain other information about, the
underlying funds. These summaries do not reflect all of the investment policies
and strategies that are disclosed in each underlying fund's prospectus, and are
not an offer of the underlying funds' shares. The underlying funds in which the
funds intend to invest may change from time to time and the funds may invest in
underlying funds in addition to those described below at the discretion of
Pioneer without prior notice to or approval of shareholders. The prospectus and
SAI for each underlying fund is available on the SEC's website as well as on our
website at www.pioneerfunds.com.

Each underlying fund normally will be invested according to its investment
strategy. However, an underlying fund also may have the ability to invest
without limitation in money market instruments or other investments for
temporary, defensive purposes.

The underlying funds that invest primarily in equity securities are:

assets in equity securities, primarily of U.S. issuers. For purposes of the
fund's investment policies, equity securities include common stocks, convertible
debt and other equity instruments, such as depositary receipts, warrants, rights
and preferred stocks.

Investment objective

Long term capital growth.

Principal investment strategies

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in equity securities of U.S.
issuers. The fund invests primarily in securities, traded in the U.S., of
issuers that the subadviser believes have substantial international activities.
In evaluating whether an issuer has substantial international activities, the
subadviser considers the degree to which the issuer has non-U.S. reported sales
and revenues, operating earnings or tangible assets. The fund may invest up to
20% of the value of its investments in equity securities of non-U.S. issuers
that are traded in U.S. markets.

borrowings, if any, for investment purposes) in equity securities of large
capitalization U.S. companies. Large capitalization companies have market
capitalizations at the time of acquisition of $3 billion or more. The fund
anticipates that the average weighted market capitalization of the companies in
the fund's portfolio will be significantly higher that $3 billion. The equity
securities in which the fund principally invests are common stocks, preferred
stocks, depositary receipts and convertible debt, but the fund may invest in
other types of equity securities to a lesser extent, such as warrants and
rights.

Principal investment strategies

Normally, the fund invests at least 80% of its total assets in equity securities
of non-U.S. issuers. These issuers may be located in both developed and emerging

issuers organized in Japan or the United Kingdom or in securities quoted or

substantial portion of the fund's assets in such countries or currencies will
subject the fund to the risks of adverse securities markets, exchange rates and
social, political or economic events which may occur in those countries.

The fund may invest without limitation in securities of issuers located in
countries with emerging economies or securities markets, but will not invest
more than 25% of its total assets in securities of issuers located in any one

The underlying funds that invest primarily in debt securities are:

Pioneer Bond Fund

Investment objective

To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the fund's portfolio.

Principal investment strategies

The fund invests primarily in:

      o     Debt securities issued or guaranteed by the U.S. government or its
            agencies and instrumentalities,

      o     Debt securities, including convertible debt, of corporate and other
            issuers rated at least investment grade at the time of investment,
            and comparably rated commercial paper,

                                       26



      o     Cash and cash equivalents, certificates of deposit, repurchase
            agreements maturing in one week or less and bankers' acceptances.

Normally, the fund invests at least 80% of its total assets in these securities.
In addition, the fund may invest up to 20% of its total assets in debt
securities rated below investment grade or, if unrated, of equivalent quality as
determined by Pioneer. Cash and cash equivalents include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from
the sale of the fund's portfolio investments.

Pioneer

Pioneer High Yield Fund

Investment objective

Maximize total return through a combination of income and capital appreciation.

Principal investment strategies

Normally, the fund invests at least 80% of its total assets in below investment
grade (high yield) debt securities and preferred stocks. These high yield
securities may be convertible into the equity securities of the issuer. Debt
securities rated below investment grade are commonly referred to as "junk bonds"
and are considered speculative. Below investment grade debt securities involve
greater risk of loss, are subject to greater price volatility and are less
liquid, especially during periods of economic uncertainty or change, than higher
rated debt securities.

            agencies or instrumentalities

Normally, at least 80% of the fund's net assets are invested in debt securities

equivalents. Cash and cash equivalents may include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from
the sale of the fund's portfolio investments.

      o     U.S. and foreign corporate issuers

Pioneer Strategic Income Fund

Investment objective

A high level of current income.

Principal investment strategies

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in debt securities. The fund has
the flexibility to invest in a broad range of issuers and segments of the debt
securities markets. Pioneer Investment Management, Inc., the fund's investment
adviser, allocates the fund's investments among the following three segments of
the debt markets:

      o     Below investment grade (high yield) securities of U.S. and non-U.S.
            issuers

      o     Investment grade securities of U.S. issuers

      o     Investment grade securities of non-U.S. issuers

Pioneer's allocations among these segments of the debt markets depend upon its
outlook for economic, interest rate and political trends. The fund invests
primarily in:

      o     Debt securities issued or guaranteed by the U.S. government, its
            agencies or instrumentalities or non-U.S. governmental entities

                                       28



      o     Debt securities of U.S. and non-U.S. corporate issuers, including
            convertible debt

      o     Mortgage-backed and asset-backed securities

The fund's investments may have fixed or variable principal payments and all
types of interest rate payment and reset terms, including fixed rate, adjustable
rate, zero coupon, contingent, deferred, payment in kind and auction rate
features. The fund invests in securities with a broad range of maturities.

Depending upon Pioneer's allocation among market segments, up to 70% of the
fund's total assets may be in debt securities rated below investment grade at
the time of purchase or determined to be of equivalent quality by Pioneer. Up to
20% of the fund's total assets may be invested in debt securities rated below
CCC by Standard & Poor's Ratings Group or the equivalent by another nationally
recognized statistical rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities.

As with all fixed income securities, the market values of convertible debt
securities tend to decline as interest rates increase and, conversely, to
increase as interest rates decline. However, when the market price of the common
stock underlying a convertible security exceeds the conversion price, the
convertible security tends to reflect the market price of the underlying common
stock.

Depending upon Pioneer's allocation among market segments, up to 85% of the
fund's total assets may be in debt securities of non-U.S. corporate and
governmental issuers, including debt securities of corporate and governmental
issuers in emerging markets.

                                  PROPOSAL 1(m)

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

      The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

      Each Fund is structured as a "fund of funds," which means all of its
assets are invested in other mutual funds ("underlying funds"). Your Fund
invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in
other Pioneer funds but is seeking an exemptive order from the Securities and
Exchange Commission that would permit the Pioneer Fund to invest, in addition,
in mutual funds that are not managed by Pioneer. To the extent that Pioneer
receives an order from the Securities and Exchange Commission that permits
Pioneer to invest in such other non-Pioneer underlying funds, Pioneer and the
Pioneer Fund intend to rely on such order, subject to any applicable conditions
of the order. In the table below, if a row extends across the entire table, the
policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

                             Pioneer Ibbotson Moderate Allocation Fund:

                             Because this is a moderate allocation fund, the majority of Pioneer Ibbotson Moderate
                             Allocation Fund's assets will be invested in equity and bond funds, although a portion of its
                             assets will be invested in cash, cash equivalents, or in money market funds. Under normal
                             circumstances, Pioneer Ibbotson Moderate Allocation Fund initially expects to invest its assets
                             among asset classes in the following ranges:

                             Short-Term
                             Investments         Equity Fund         Fixed Income Fund
                             Allocation          Allocation          Allocation

                             Based upon the analysis described under "Asset allocation process," the fund initially expects
                             to invest its assets in underlying mutual funds within the following ranges:

                             Fund Name                                               Percentage of Fund Holdings

                             The Fund may change its target allocation to each asset class, the underlying fund in each
                             asset class (including adding or deleting funds) or target allocations to each underlying fund
                             without prior approval from or notice to shareholders. Certain of the Pioneer Funds into which
                             the AmSouth Funds are being reorganized are not currently included in the above list of funds
                             underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such additional
                             Pioneer Funds in the list of permitted investments for the Pioneer Fund into which your Fund is
                             being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those additional
                             Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced.

                             Appendix A contains a summary description of each of the underlying Pioneer funds.

                             Normally, the Fund invests substantially all of its assets in underlying funds to meet its
                             investment objective. However, the Fund may invest a portion of its assets in cash, cash
                             equivalents or in money market funds. The underlying funds may also invest a portion of their
                             assets in money market funds, securities with remaining maturities of less than one year, cash
                             equivalents or may hold cash. For temporary defensive purposes, including during periods of
                             unusual cash flows, the Fund and each of the underlying funds may depart from its principal
                             investment strategies and invest part or all of its assets in these securities or may hold
                             cash. During such periods, the Fund may not be able to achieve its investment objective. The
                             Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in
                             which the Fund normally invests have extraordinary risks due to political or economic factors
                             and in other extraordinary circumstances.

                             The Fund uses a "first-in, first-out" method
                             to determine how long you have held your
                             shares. This means that if you purchased
                             shares on different days, the shares purchased
                             first will be considered redeemed first for
                             purposes of determining whether the redemption
                             fee will be charged.

                             The fee will be charged on all covered
                             redemptions and exchanges, including those
                             made through retirement plan, brokerage and
                             other types of omnibus accounts (except where
                             it is not practical for the plan administrator
                             or brokerage firm to implement the fee). The
                             Fund will not impose the redemption fee on a
                             redemption or exchange of shares purchased

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on an investment in a Fund or a Fund may not perform as well as
other investment options.

Fund of funds structure and layering of fees

                                       9



      Each Fund is structured as a fund of funds. Each Fund's investments are
focused in the underlying funds, so the Fund's investment performance is
directly related to the performance of the underlying funds. Each Fund's net
asset value will be affected by the performance of the equity and bond markets
and the value of the mutual funds in which the fund invests. Since the Funds
mainly invest in the underlying funds, as opposed to other types of securities,
the Funds do not have the same flexibility in their portfolio holdings as many
mutual funds. In addition, each Fund indirectly pays a portion of the expenses
incurred by the underlying funds. Consequently, an investment in a Fund entails
more direct and indirect expenses than a direct investment in the underlying
funds. For instance, you will pay management fees and operating expenses of both
the Fund and the underlying funds.

      The underlying funds will not necessarily make consistent investment
decisions, which may also increase your costs. One underlying fund may buy the
same security that another underlying fund is selling. You would indirectly bear
the costs of both trades without achieving any investment purpose. These
transactions may also generate taxable gains. You may receive taxable gains from
portfolio transactions by the underlying funds as well as taxable gains from the
Fund's transactions in shares of the underlying funds.

      Currently, Pioneer manages all of the funds underlying the Pioneer Fund.
Because the portfolio management teams of each of the underlying Pioneer funds
may draw upon the resources of the same equity and fixed income analyst team or
may share common investment management styles or approaches, the underlying
funds may hold many common portfolio positions, reducing the diversification
benefits of an asset allocation style.

Equity investments

      Equity funds invest primarily in equity securities (such as stocks), which
are more volatile and carry more risks than some other forms of investment. When
the value of the stocks held by an underlying equity fund goes down, the value
of your investment in the fund will be affected.

      The underlying equity funds have risks associated with investing in equity
securities. An equity fund could underperform other investments if:

      o     The stock market goes down (this risk may be greater in the short
            term)
      o     The fund's equity investments do not have the growth potential or
            value characteristics originally expected
      o     Stocks selected for income do not achieve the same return as
            securities selected for capital growth
      o     The types of stocks in which the fund invests or the fund's
            investment approach fall out of favor with investors

Fixed income investments

      Fixed income funds primarily invest in debt securities, such as government
securities, investment grade corporate securities, junk bonds, mortgaged backed
securities, asset-backed securities, and money market securities. The value of
your investment in the fund will change as the value of investments of the
underlying funds increases and decreases.

      The underlying fixed income funds have risks associated with investing in
debt securities. A fund could underperform other investments if:

      o     Interest rates go up causing the value of the fund's portfolio to
            decline
      o     The issuer of a debt security owned by the fund defaults on its
            obligation to pay principal or interest or has its credit rating
            downgraded
      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay earlier than scheduled, forcing
            the fund to reinvest in lower yielding securities. This is known as
            call or prepayment risk
      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk
      o     The investment manager's judgment about the attractiveness, relative
            value or potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

      Compared to large companies, small and mid-sized companies, and the market
for their equity securities, are likely to:

      o     Be more sensitive to changes in the economy, earnings results and
            investor expectations
      o     Have more limited product lines and capital resources
      o     Experience sharper swings in market values
      o     Be harder to sell at the times and prices Pioneer thinks appropriate
      o     Offer greater potential for loss than other U.S. equity securities

Equity securities of real estate industry issuers

            Specific risks associated with the real estate industry include:
      o     The U.S. or a local real estate market declines due to adverse
            economic conditions, overbuilding and high vacancy rates, reduced or
            regulated rents or other causes
      o     Interest rates go up. Rising interest rates can adversely affect the
            availability and cost of financing for property acquisitions and
            other purposes and reduce the value of a REIT's fixed income
            investments
      o     The values of properties owned by a REIT or the prospects of other
            real estate industry issuers may be hurt by property tax increases,
            zoning changes, other governmental actions, environmental
            liabilities, natural disasters or increased operating expenses
      o     A REIT in an underlying fund's portfolio is, or is perceived by the
            market to be, poorly managed

Non-U.S. securities

      Investing in non-U.S. issuers, including emerging market issuers, may
involve unique risks compared to investing in securities of issuers in the U.S.
These risks are more pronounced to the extent the fund invests in issuers in the
lesser-developed emerging markets or in one region, such as Europe or the
Pacific Rim. These risks may include:

      o     Less information about the non-U.S. issuers or markets may be
            available due to less rigorous disclosure or accounting standards or
            regulatory practices
      o     Adverse effect of currency exchange rates or controls on the value
            of the fund's investments
      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession
      o     Economic, political and social developments may adversely affect
            securities markets
      o     Withholding and other non-U.S. taxes may decrease the fund's return

High yield/below investment grade debt securities

      Investment in high yield securities involves substantial risk of loss.
These securities are considered speculative with respect to the issuer's ability
to pay interest and principal and are susceptible to default or decline in
market value due to adverse economic and business developments. The market
values for high yield securities tend to be very volatile, and these securities
are less liquid than investment grade debt securities. For these reasons, your
investment in the fund is subject to the following specific risks:

      o     Increased price sensitivity to changing interest rates and
            deteriorating economic environment
      o     Greater risk of loss due to default or declining credit quality
      o     Adverse company specific events are more likely to render the issuer
            unable to make interest and/or principal payments
      o     A negative perception of the high yield market develops, depressing
            the price and liquidity of high yield securities. This negative
            perception could last for a significant period of time

Derivatives

      Certain underlying funds may use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts 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. The underlying funds may use
derivatives for a variety of purposes, including:

      o     As a hedge against adverse changes in stock market prices, interest
            rates or currency exchange rates
      o     As a substitute for purchasing or selling securities
      o     To increase the fund's return as a non-hedging strategy that may be
            considered speculative

                                       11



      Even a small investment in derivatives can have a significant impact on a
fund's exposure to stock market values, interest rates or currency exchange
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.

The table above shows the impact of taxes on AmSouth Strategic Portfolios:
Moderate Growth & Income Portfolio's returns. After-tax returns are only shown
for Class A shares and Class I shares and may vary for Class B shares. The
Fund's after-tax returns are calculated using the highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes. In certain cases, the figure representing "Return After Taxes on
Distributions and Sale of Fund Shares" may be higher than the other return
figures for the same period. A higher after-tax return results when a capital
loss occurs upon redemption and translates into an assumed tax deduction that
benefits the shareholder. Please note that actual after-tax returns depend on an
investor's tax situation and may differ from those shown. Also note that
after-tax returns shown are not relevant to shareholders who hold Fund shares
through tax-deferred arrangements, such as 401(k) plans or individual retirement
accounts.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines

                                       15



      over six years, starting with year one and ending in year seven from: 5%,
      4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of
      shares acquired in the ISG combination), Class B shares automatically
      convert to Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.33% for Class
      A shares, 0.33% for Class B shares and 0.28% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time. Pioneer has contractually agreed not to impose
      all or a portion of its fees or to limit other direct ordinary operating
      expenses to the extent required to reduce expenses, other than "Estimated
      average expense ratio of underlying funds," to 0.74% of the average daily
      net assets attributable to Class A shares and 1.52% of average daily net
      assets attributable to Class B shares. This expense limitation is in
      effect for Class A shares until December 1, 2008 and in effect for Class B
      until December 1, 2006. There can be no assurance that Pioneer will extend
      these expense limitations past such dates. The expense limitation does not
      limit the expenses of the underlying funds indirectly incurred by a
      shareholder.

(6)   The management fee payable by the Pioneer Fund is equal to 0.13% of
      average daily net assets attributable to the Pioneer Fund's investments in
      underlying funds managed by Pioneer and cash and 0.17% of average daily
      net assets attributable to other investments, including underlying funds
      that are not managed by Pioneer, with breakpoints at incremental asset
      levels. Since initially all of the underlying funds are managed by
      Pioneer, the management fee will initially be 0.13% of average daily net
      assets.

(7)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

(8)   Class Y shares of the Pioneer Fund are being offered for the first time in
      connection with the Reorganization.

The hypothetical example below helps you compare the cost of investing in each
Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods
shown, (b) you reinvest all dividends and distributions, (c) your investment has
a 5% return each year, and (d) each Fund's gross operating expenses remain the
same. The examples are for comparison purposes only and are not a representation
of either Fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Strategic Portfolios: Moderate Growth & Income Portfolio.
The Trustees considered the following matters, among others, in approving the
proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your Fund's investment
adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $15.7 billion in fixed income securities. Pioneer is part of
the global asset management group of UniCredito Italiano S.p.A., one of the
largest banking groups in Italy, providing investment management and financial
services to mutual funds, institutional and other clients. As of December 31,
2004, assets under management of UniCredito Italiano S.p.A. were approximately
$175 billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

                                       17



     Third, Pioneer Ibbotson Moderate Allocation Fund's management fee (0.17% of
average daily net assets) is lower than the advisory fee of your Fund (0.20% of
average daily net assets). Both the historical and estimated pro forma expenses
of the Pioneer Fund, after giving effect to the Reorganization, on a gross and
net basis are lower than your Fund's gross and net operating expenses. The
aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule
12b-1 shareholder servicing fees paid by the Class A and Class B shares of both
Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1
shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares.

     Fourth, because of Pioneer distribution arrangements, Pioneer Fund has
greater potential to further increase the assets compared to your Fund. Further
assets growth is anticipated to further reduce the combined Fund's gross
operating expenses per share.

     Fifth, the Class A, B and Y shares of the Pioneer Fund received in the
Reorganization will provide AmSouth Fund shareholders with exposure to a similar
investment product as they currently have. The Trustees also noted that the
allocation decision was made by Ibbotson, a leading asset allocation adviser,
and that the Pioneer Fund intends, as soon as permitted by the SEC, to include
unaffiliated mutual funds as underlying funds.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth Fund in connection with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also
sets forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth Strategic Portfolios: Growth & Income
Portfolio approve the reorganization of their fund into Pioneer Ibbotson
Moderate Allocation Fund.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

Information about the underlying funds

The following is intended to summarize the investment objectives and primary
strategies of, and to provide you with certain other information about, the
underlying funds. These summaries do not reflect all of the investment policies
and strategies that are disclosed in each underlying fund's prospectus, and are
not an offer of the underlying funds' shares. The underlying funds in which the
funds intend to invest may change from time to time and the funds may invest in
underlying funds in addition to those described below at the discretion of
Pioneer without prior notice to or approval of shareholders. The prospectus and
SAI for each underlying fund is available on the SEC's website as well as on our
website at www.pioneerfunds.com.

Each underlying fund normally will be invested according to its investment
strategy. However, an underlying fund also may have the ability to invest
without limitation in money market instruments or other investments for
temporary, defensive purposes.

The underlying funds that invest primarily in equity securities are:

Pioneer Fund

Investment objective

Reasonable income and capital growth.

Principal investment strategies

The fund invests in a broad list of carefully selected, reasonably priced
securities rather than in securities whose prices reflect a premium resulting

and revenues, operating earnings or tangible assets. The fund may invest up to

Pioneer Bond Fund

Investment objective

To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the fund's portfolio.

Principal investment strategies

The fund invests primarily in:

      o     Debt securities issued or guaranteed by the U.S. government or its
            agencies and instrumentalities,

      o     Debt securities, including convertible debt, of corporate and other
            issuers rated at least investment grade at the time of investment,
            and comparably rated commercial paper,

                                       26



      o     Cash and cash equivalents, certificates of deposit, repurchase
            agreements maturing in one week or less and bankers' acceptances.

Normally, the fund invests at least 80% of its total assets in these securities.
In addition, the fund may invest up to 20% of its total assets in debt
securities rated below investment grade or, if unrated, of equivalent quality as
determined by Pioneer. Cash and cash equivalents include cash balances, accrued
interest and receivables for items such as the proceeds, not yet received, from

Pioneer High Yield Fund

Investment objective

Maximize total return through a combination of income and capital appreciation.

Principal investment strategies

Normally, the fund invests at least 80% of its total assets in below investment
grade (high yield) debt securities and preferred stocks. These high yield
securities may be convertible into the equity securities of the issuer. Debt
securities rated below investment grade are commonly referred to as "junk bonds"

greater risk of loss, are subject to greater price volatility and are less
liquid, especially during periods of economic uncertainty or change, than higher
rated debt securities.

Pioneer Strategic Income Fund

Investment objective

A high level of current income.

Principal investment strategies

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in debt securities. The fund has
the flexibility to invest in a broad range of issuers and segments of the debt
securities markets. Pioneer Investment Management, Inc., the fund's investment
adviser, allocates the fund's investments among the following three segments of
the debt markets:

      o     Below investment grade (high yield) securities of U.S. and non-U.S.
            issuers

      o     Investment grade securities of U.S. issuers

      o     Investment grade securities of non-U.S. issuers

Pioneer's allocations among these segments of the debt markets depend upon its
outlook for economic, interest rate and political trends. The fund invests
primarily in:

      o     Debt securities issued or guaranteed by the U.S. government, its
            agencies or instrumentalities or non-U.S. governmental entities

                                       28



      o     Debt securities of U.S. and non-U.S. corporate issuers, including
            convertible debt

      o     Mortgage-backed and asset-backed securities

The fund's investments may have fixed or variable principal payments and all
types of interest rate payment and reset terms, including fixed rate, adjustable
rate, zero coupon, contingent, deferred, payment in kind and auction rate
features. The fund invests in securities with a broad range of maturities.

Depending upon Pioneer's allocation among market segments, up to 70% of the
fund's total assets may be in debt securities rated below investment grade at
the time of purchase or determined to be of equivalent quality by Pioneer. Up to
20% of the fund's total assets may be invested in debt securities rated below
CCC by Standard & Poor's Ratings Group or the equivalent by another nationally
recognized statistical rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities.

As with all fixed income securities, the market values of convertible debt
securities tend to decline as interest rates increase and, conversely, to
increase as interest rates decline. However, when the market price of the common
stock underlying a convertible security exceeds the conversion price, the
convertible security tends to reflect the market price of the underlying common
stock.

Depending upon Pioneer's allocation among market segments, up to 85% of the
fund's total assets may be in debt securities of non-U.S. corporate and
governmental issuers, including debt securities of corporate and governmental
issuers in emerging markets.

                             shares. This means that if you purchased
                             shares on different days, the shares purchased
                             first will be considered redeemed first for
                             purposes of determining whether the redemption
                             fee will be charged.

                             made through retirement plan, brokerage and

Comparison of Principal Risks of Investing in the Funds

Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

      o     Interest rates go up, causing the value of the Fund's investments to
            decline

      o     The issuer of a security owned by the Fund defaults on its
            obligation to pay principal and/or interest or has its credit rating
            downgraded

      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay principal earlier than scheduled,
            forcing the Fund to reinvest in lower yielding securities. This is
            known as call or prepayment risk

      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk

      o     The adviser's judgment about the attractiveness, relative value or
            potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

      o     To the extent that the Fund invests significantly in high yield
            securities, its exposure to the credit risks associated with such
            securities may be greater, its income and net asset value may be
            more volatile and it may be more difficult to achieve preservation
            of principal

      Government sponsored entities such as the Federal Home Loan Mortgage
Corporation (Freddie Mac), the Federal National Mortgage Association (FNMA) and
the Federal Home Loan Banks (FHLBs), although chartered or sponsored by
Congress, are not funded by congressional appropriations and the debt and
mortgage-backed securities issued by them are neither guaranteed nor issued by
the U.S. government.

      To the extent a Fund invest significantly in mortgage-backed securities,
its exposure to prepayment and extension risks may be greater than if it
invested in other fixed income securities.

      At times, more than 25% of Pioneer Bond Fund's assets may be invested in
the same market segment, such as financials. To the extent the Fund emphasizes
investments in a market segment, the Fund will be subject to a greater degree to
the risks particular to the industries in that segment, and may experience
greater market fluctuation, than a fund without the same focus. For example,
industries in the financial segment, such as banks, insurance companies,
broker-dealers and REITs, may be sensitive to changes in interest rates and
general economic activity and are subject to extensive government regulation.

Past Performance

      Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The table
shows average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

The table above shows the impact of taxes on AmSouth High Quality Bond Fund's
returns. After-tax returns are only shown for Class A shares and Class I shares
and may vary for Class B shares. The Fund's after-tax returns are calculated
using the highest individual federal marginal income tax rates and do not
reflect the impact of state and local taxes. In certain cases, the figure
representing "Return After Taxes on Distributions and Sale of Fund Shares" may
be higher than the other return figures for the same period. A higher after-tax
return results when a capital loss occurs upon redemption and translates into an
assumed tax deduction that benefits the shareholder. Please note that actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. Also note that after-tax returns shown are not relevant to
shareholders who hold Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.49% for Class
      A shares, 0.50% for Class B shares and 0.35% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

(7)   The expenses in the table above reflect the expense limitation in effect
      through November 1, 2007, under which Pioneer has contractually agreed to
      limit ordinary operating expenses to the extent required to reduce Class A
      expenses to 1.00% of the average daily net assets attributable to Class A
      shares. There can be no assurance that Pioneer will extend the expense
      limitation beyond November 1, 2007.

(8)   The expenses in the table above reflect the expense limitation in effect
      through November 1, 2006, under which Pioneer has contractually agreed to
      limit ordinary operating expenses to the extent required to reduce Class B
      expenses to 1.90% of the average daily net assets attributable to Class B
      shares. There can be no assurance that Pioneer will extend the expense
      limitation beyond November 1, 2006.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, and (e) the expense limitation for your Fund is in effect for
year one. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of Amsouth High Quality Bond Fund. The Trustees considered the
following matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your Fund's investment
adviser was necessary. In the absence of the Reorganization, such a change would
be more likely to motivate shareholders invested in reliance on AAMI's role to
withdraw from the Fund, thereby reducing fund size and increasing fund expense
ratios.

      Second, the historical investment performance of Pioneer Bond Fund is
comparable to your AmSouth Fund's investment performance. For the one, five and
ten year periods ended December 31, 2004, Class A shares of Pioneer Bond Fund
had an average annual return of 0.95% (one year); 6.86% (five year); and 6.69%
(ten year), compared to an average annual return of the Class A shares of your
AmSouth Fund of -1.45% (one year); 6.14% (five year); and 7.64% (ten year),
respectively, during the same period. The Trustees also noted that, for the one
and five year periods ended March 31, 2005, Class A shares of Pioneer Bond Fund
had an average annual return of 2.67% (one year); and 7.60% (five year),
compared to an average annual return of the Class A shares of your AmSouth Fund
of -0.25% (one year); and 6.25% (five year), during the same period. In
addition, the Trustees considered the track record of Pioneer in managing equity
and fixed income mutual funds.

      Third, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $15.7 billion in fixed income searches. Pioneer is part of the
global asset management group of UniCredito Italiano S.p.A., one of the largest
banking groups in Italy, providing investment management and financial services
to mutual funds, institutional and other clients. As of December 31, 2004,
assets under management of

                                       13



UniCredito Italiano S.p.A. were approximately $175 billion worldwide.
Shareholders of your AmSouth Fund would become part of a significantly larger
family of funds that offers a more diverse array of investment options and
enhanced shareholder account options. The Pioneer family of mutual funds offers
over 80 funds, including domestic and international equity and fixed income
funds and a money market fund that will be available to your AmSouth Fund's
shareholders through exchanges.

     Fourth, the aggregate management and administration fees incurred by your
AmSouth Fund are higher than the management fee paid by Pioneer Bond Fund. The
aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule
12b-1 shareholder servicing fees paid by the Class A and Class B shares of both
Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1
shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares.
With respect to Class I shares, both the gross and net expenses of the Pioneer
Fund are lower than your AmSouth Fund. While the pro forma expenses are
estimated to be lower for your Class A and B Shares on a gross basis, the
expenses will be higher on a net basis. The lower net expenses of your AmSouth
Fund are a result of voluntary expense limitations that may be discontinued at
any time. The trustees considered the positive factors associated with the
Reorganization, such as greater fund assets and potential for growth, to
outweigh the negative factors, such as the increase in expenses.

     Fifth, the Class A, B and Y shares of Pioneer Bond Fund received in the
Reorganization will provide AmSouth High Quality Bond Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of your Fund in connection with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

     The following table sets forth the capitalization of each Fund as of May

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

personal property tax, you could lose money on your investment or not make as
much as if you invested elsewhere if:

      o     Interest rates go up, causing the value of the Fund's investments to
            decline

      o     The issuer of a security owned by the Fund defaults on its
            obligation to pay principal and/or interest or has its credit rating
            downgraded

      o     New federal or state legislation adversely affects the tax-exempt
            status of securities held by the Fund or the financial ability of
            municipalities to repay these obligations

      o     The issuer of a security owned by the Fund may not be able to make
            timely payments because of a general economic downturn or increased
            governmental costs

      o     Because the Fund concentrates its investments in a single state,
            there may be more fluctuation in the value of its securities than is
            the case for mutual funds whose portfolios are more geographically
            diverse. Because the Fund invests primarily in securities issued by
            Florida and its municipalities, it is more vulnerable to unfavorable
            developments in Florida than are funds that invest in municipal
            securities of many states. Unfavorable developments in any economic
            sector may adversely affect the overall Florida municipal market

      o     The adviser is incorrect in its expectation of changes in interest
            rates or the credit quality of an issuer

Although distributions of interest income from the Fund's tax-exempt securities
are generally exempt from regular federal income tax and Florida intangible
personal property tax, distributions from other sources, including capital gain
distributions and any gains on the sale of your shares, are not. You should
consult a tax adviser about state and local taxes on your Fund distributions.

At times, more than 25% of the Fund's assets may be invested in the same market
segment, such as financials. To the extent the Fund emphasizes investments in a
market segment, the Fund will be subject to a greater degree to the risks
particular to the industries in that segment, and may experience greater market
fluctuation, than a fund without the same focus. For example, industries in the
financial segment, such as banks, insurance companies, broker-dealers and REITs,
may be sensitive to changes in interest rates and general economic activity and
are subject to extensive government regulation.

The Fund generally invests in a limited number of securities and, as a result,
the Fund's performance may be more volatile than the performance of funds
holding more securities.

    based on the historical performance of the Fund's Class A shares (without

    shares has been restated to reflect the Fund's Class B shares distribution
    (12b-1) fees and the contingent deferred sales charge.

(3) Performance for the Class I shares, which were first offered on 9/2/97, is
    based on the historical performance of the Fund's Class A shares (without

    The table above shows the impact of taxes on the AmSouth Florida Tax-Exempt
    Fund's returns. The Fund's after-tax returns are calculated using the
    highest individual federal marginal income tax rates and do not reflect the
    impact of state and local taxes. In certain cases, the figure representing
    "Return After Taxes on Distributions and Sale of Fund Shares" may be higher
    than the other return figures for the same period. A higher after-tax return
    results when a capital loss occurs upon redemption and translates into an
    assumed tax deduction that benefits the shareholder. Please note that actual
    after-tax returns depend on an investor's tax situation and may differ from
    those shown. Also note that after-tax returns shown

                                       10

(1) AmSouth Bank or other financial institutions may charge their customer
    account fees for automatic investment and other cash management services
    provided in connection with investment in the Fund.

(2) Sales charges may be reduced depending upon the amount invested or, in
    certain circumstances, waived. Class A shares of the Pioneer Fund bought as
    part of an investment of $1 million or more are not subject to an initial
    sales charge, but may be charged a CDSC of 1.00% if sold within one year of
    purchase.

(3) For Class B shares purchased prior to the combination of AmSouth Funds with
    ISG Funds, the CDSC on such Class B shares held continuously declines over
    six years, starting with year one and ending in year seven from: 4%, 3%, 3%,
    2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
    declines over six years, starting with year one and ending in year seven
    from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the
    case of shares acquired in the ISG combination), Class B shares
    automatically convert to Class A shares.

(4) To discourage short-term trading, a redemption fee of 2.00% will be charged
    on sales or exchanges of Class A, Class B and Class I shares of your AmSouth
    Fund made within 7 days of the date of purchase. A wire transfer fee of
    $7.00 will be deducted from the amount of your redemption if you request a
    wire transfer.

(5) Other expenses for the AmSouth Fund are being limited to 0.33% for Class A
    shares, 0.33% for Class B shares and 0.18% for Class I shares. Any fee
    waiver or expense reimbursement arrangement is voluntary and may be
    discontinued at any time.

(6) The Pioneer Fund's total annual operating expenses have not been reduced by
    any expense offset arrangements.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Florida Tax-Exempt Fund. The Trustees considered the
following matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your Amsouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. . In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $2 billion in municipal securities. Pioneer is part of the
global asset management group of UniCredito Italiano S.p.A., one of the largest
banking groups in Italy, providing investment management and financial services
to mutual funds, institutional and other clients. As of December 31, 2004,
assets under management of UniCredito Italiano S.p.A. were approximately $175
billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

     Third, Pioneer Florida Tax Free Income Fund's management fee (0.50% of
average daily net assets on the first $250 million, 0.45% on assets greater than
$250 million to $750 million, and 0.40% on assets greater than $750 million)
will be the same as or lower than the advisory fee of your Fund (0.50% of
average daily net assets). The estimated pro forma expenses on a total basis of
the Pioneer Fund after giving effect to the Reorganizations are expected to
decline for all classes of shares. The estimated pro forma expenses on a net
basis are also expected to decline for Class A shares. Although the estimated
pro forma operating expenses for the AmSouth Fund's Class B and I shares are
lower on a gross basis, the expenses are higher on a net basis. AmSouth Bank and
its affiliates have informed the trustees that they will discontinue their
expense limitations in the future. The trustees considered the positive factors
associated with the reorganization to outweigh the negative factors, such as the
increase in expenses. The aggregate Rule 12b-1 distribution and shareholder
servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A
and Class B shares of both Funds will be the same. Moreover, your AmSouth Fund's
Class I shares pay a non 12b-1 shareholder servicing fee that will not be paid
by the Pioneer Fund's Class Y shares. In addition, the broader distribution
arrangements of the Pioneer Fund offer greater potential for further asset
growth and reduce per share expenses.

      Fourth, the Class A, B and Y shares of Pioneer Florida Tax Free Income
Fund received in the Reorganization will provide AmSouth Florida Tax-Exempt Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth Florida Tax-Exempt Fund in connection with the
Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

      o     Interest rates go up, causing the value of the Fund's investments to
            decline

      o     The issuer of a security owned by the Fund defaults on its
            obligation to pay principal and/or interest or has its credit rating
            downgraded

      o     New federal or state legislation adversely affects the tax-exempt
            status of securities held by the Fund or the financial ability of
            municipalities to repay these obligations

      o     To the extent the Fund concentrates its investments in a single
            state or securities the payments on which are dependent upon a
            single industry, the Fund will be more susceptible to risks
            associated with that state or industry

      o     The adviser is incorrect in its expectation of changes in interest
            rates or the credit quality of an issuer

      In addition, at times, more than 25% of Pioneer Tax Free Income Fund's
assets may be invested in the same market segment, such as financials or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

      Pioneer Tax Free Income Fund may also invest up to 10% of its net assets
in debt securities rated below investment grade or, if unrated, of equivalent
quality as determined by Pioneer. Debt securities rated below investment grade
are

                                        8



commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher quality debt securities.

      AmSouth High Quality Municipal Bond Fund may invest 25% or more of its
total assets in bonds, notes and warrants generally issued by or on behalf of
the State of Alabama and its political subdivisions, the interest on which, in
the opinion of the issuer's bond counsel at the time of issuance, is exempt from
both federal income tax and Alabama personal income tax and is not treated as a
preference item for purposes of the federal alternative minimum tax. By
concentrating its investments in securities issued by Alabama and its
municipalities, the Fund will be more vulnerable to unfavorable developments in
Alabama than funds that are more geographically diversified. Additionally,
because of the relatively small number of issuers of Alabama municipal
securities, the Fund is likely to invest in a limited number of issuers.

Past Performance

      Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)   The Fund commenced operations on 7/1/97, through a transfer of assets from
      certain collective trust fund ("commingled") accounts advised by AmSouth
      Bank, using substantially the same investment objective, policies and
      methodologies as the Fund. The quoted before-tax returns of the Fund
      includes the performance of the commingled accounts for periods dating
      back to 7/31/93, and prior to the Fund's commencement of operations,
      restated to reflect the expenses associated with the Fund. The commingled
      accounts were not registered with the SEC and, therefore, were not subject
      to the investment restrictions imposed by law on registered mutual funds.
      If the commingled accounts had been registered, their performance may have
      been adversely affected. After-tax returns reflect performance since
      7/1/97, and do not include the performance of the commingled accounts
      prior to that date. Class A shares were first offered on 7/1/97.

(2)   Performance for the Class B shares, which were first offered on 2/3/99, is
      based on the historical performance of the Fund's Class A shares,
      including the performance of the commingled accounts (without sales
      charge) prior to that date. The commingled accounts were managed using
      substantially the same investment objective, policies and methodologies as
      the Fund. The historical performance of the Class B shares has been
      restated to reflect the Fund's Class B shares distribution (12b-1) fees
      and the contingent deferred sales charge.

(3)   Performance for the Class I shares, which were first offered on 9/2/97, is
      based on the historical performance of the Fund's Class A shares,
      including the performance of the commingled accounts (without sales
      charge) prior to that date. The commingled accounts were managed using
      substantially the same investment objective, policies and methodologies as
      the Fund.

(4)   Merrill Lynch 1-12 Year Municipal Bond Index, an unmanaged index generally
      representative of municipal bonds with intermediate maturities of no less
      than one year and no more than twelve years, is for reference only, does
      not mirror the Fund's investments, and reflects no deduction for fees,
      expenses or taxes.

      The table above shows the impact of taxes on the AmSouth High Quality
      Municipal Bond Fund's returns. The Fund's after-tax returns are calculated
      using the highest individual federal marginal income tax rates and do not
      reflect the impact of state and local taxes. In certain cases, the figure
      representing "Return After Taxes on Distributions and Sale of Fund Shares"
      may be higher than the other return figures for the same period. A higher
      after-tax return results when a capital loss occurs upon redemption and
      translates into an assumed tax deduction that benefits the shareholder.
      Please note that actual after-tax returns depend on an investor's tax
      situation and may differ from those shown. Also note that after-tax
      returns shown are not relevant to investors who hold their Fund shares
      through tax-deferred arrangements, such as 401(k) plans or individual
      retirement accounts.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for your AmSouth Fund are being limited to 0.38% for Class
      A shares, 0.38% for Class B shares and 0.23% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) and each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth High Quality Municipal Bond Fund. The Trustees considered
the following matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

      Second, after the Reorganization, the combined Fund will have an asset
size substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

      Third, the historical investment performance of Pioneer Tax Free Income
Fund is better than your AmSouth Fund's investment performance. For the one,
five and ten year periods ended December 31, 2004, Class A shares of Pioneer Tax
Free Income Fund had an average annual return of 0.05% (one year); 5.66% (five
year); and 5.88% (ten year) compared to an average annual return of the Class A
shares of your AmSouth Fund of -2.55% (one year); 4.42% (five year); and 4.55%
(ten year), respectively, during the same period. The trustees also considered
performance information provided for the one, three, and five year periods ended
March 31, 2005 during which Class A shares of Pioneer Tax Free Income Fund had
an average annual return of 3.30% (one year); 5.82% (three year); and 6.10%
(five year), compared to an average annual return of the

                                       14



Class A shares of your AmSouth Fund of -0.76% (one year); 3.73% (three year);
and 4.64% (five year), respectively, during the same period. In addition, the
Trustees considered the track record of Pioneer in managing equity and fixed
income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

     Fifth, Pioneer Tax Free Income Fund's management fee will benefit from
breakpoints as assets increase as a result of the Reorganization. The aggregate
Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1
shareholder servicing fees paid by the Class A and Class B shares of both Funds
are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1
shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares.
Although your AmSouth Fund's expenses attributable to Class A and Class B shares
net of limitations are lower than the Pioneer Fund's net expenses currently and
on a pro forma basis, your AmSouth Fund may terminate such limitations at any
time. AAMI has informed the trustees that the expense waivers will be
discontinued in the future. The trustees considered the positive factors
associated with the Reorganization, such as superior performance of the Pioneer
Fund, greater fund assets and potential for growth, to outweigh the negative
factors. The gross expenses of Pioneer Fund's Class A, Class B and Class Y
shares are lower than the AmSouth Fund's gross expenses attributable to Class A,
Class B and Class I shares and are estimated to be lower on a pro forma basis
after giving effect to the Reorgnization. In addition, the net expenses of the
Class Y shares of the Pioneer Fund are lower than the net expenses of the
AmSouth Fund attributable to Class I shares and are estimated to be lower on a
pro forma basis. In addition, the broader distribution arrangement of the
Pioneer Fund offers greater potential for further increases in net assets of the
combined fund and lower per share expense ratios.

     Sixth, the Class A, B and Y shares of Pioneer Tax Free Income Fund received
in the Reorganization will provide AmSouth High Quality Municipal Bond Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Seventh, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of AmSouth High Quality Municipal Bond Fund in connection
with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      It is impossible to predict how many shares of the Pioneer Tax Free Income
Fund will actually be received and distributed by your AmSouth Fund on the
Reorganization date. The table should not be relied upon to determine the amount
of the Pioneer Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                             The Fund uses a "first-in, first-out" method to
                             determine how long you have held your shares.
                             This means that if you purchased shares on
                             different days, the shares purchased first will
                             be considered redeemed first for purposes of
                             determining whether the redemption fee will be
                             charged.

                             The fee will be charged on all covered

                             through retirement plan, brokerage and other

                             brokerage firm to implement the fee). The Fund
                             will not impose the redemption fee on a
                             redemption or exchange of shares purchased upon

Comparison of Principal Risks of Investing in the Funds

      Because each Fund primarily invests in municipal securities, the Funds are
subject to the same principal risks. You could lose money on your investment in
either Fund or not make as much as if you invested elsewhere if:

      o     Interest rates go up, causing the value of the Fund's investments to
            decline

      o     The issuer of a security owned by the Fund defaults on its
            obligation to pay principal and/or interest or has its credit rating
            downgraded

      o     New federal or state legislation adversely affects the tax-exempt
            status of securities held by the Fund or the financial ability of
            municipalities to repay these obligations

      o     To the extent the Pioneer Fund concentrates its investments in a
            single state or securities the payments on which are dependent upon
            a single industry, the Fund will be more susceptible to risks
            associated with that state or industry. By concentrating its
            investments in securities issued by Tennessee and its
            municipalities, AmSouth Tennessee Tax-Exempt Fund will be more
            vulnerable to unfavorable developments in Tennessee than funds that
            are more geographically diversified.

      o     The adviser is incorrect in its expectation of changes in interest
            rates or the credit quality of an issuer

      In addition, at times, more than 25% of Pioneer Tax Free Income Fund's
assets may be invested in the same market segment, such as financials or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

      Pioneer Tax Free Income Fund may also invest up to 10% of its net assets
in debt securities rated below investment grade or, if unrated, of equivalent
quality as determined by Pioneer. Debt securities rated below investment grade
are commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher quality debt securities.

      AmSouth Tennessee Tax-Exempt Fund is subject to risks relating to the fact
that it is non-diversified. The Fund may invest in a small number of companies
which may increase the volatility of the Fund. Accordingly, the Fund's portfolio
may be more sensitive to changes in the market value of a single company or
industry.

Past Performance

      Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)   The quoted returns reflect the performance from 3/28/94 to 3/12/00 of the
      ISG Tennessee Tax Exempt Fund, an open-end investment company that was the
      predecessor fund to the AmSouth Tennessee Tax-Exempt Fund. The ISG
      Tennessee Tax-Exempt Fund, commenced operations on 3/28/94, through a
      transfer of assets from certain collective trust fund ("commingled")
      accounts managed by First American National Bank, using substantially the
      same investment objective, policies and methodologies as the Fund. The
      quoted before-tax returns of the Fund includes the performance of the
      predecessor fund commingled accounts for periods dating back to 7/31/93,
      and prior to the Fund's commencement of operations, restated to reflect
      the expenses associated with the Fund. The commingled accounts were not
      registered with the SEC and, therefore, were not subject to the investment
      restrictions imposed by law on registered mutual funds. If the commingled
      accounts had been registered, their performance may have been adversely
      affected. After-tax returns reflect performance since 4/1/96, and do not
      include the performance of the commingled accounts prior to that date.
      Class A Shares were first offered on 3/28/94.

(2)   Performance for the Class B Shares, which were first offered on 2/24/98,
      is based on the historical performance of the Fund's Class A Shares,
      including the performance of the predecessor fund and commingled accounts
      (without sales charge) prior to that date. The predecessor fund and
      commingled accounts were managed using substantially the same investment
      objective, policies and methodologies as the Fund. The historical
      performance of the Class B Shares has been restated to reflect the Fund's
      Class B Shares distribution (12b-1) fees and the contingent deferred sales
      charge.

(3)   Performance for the Class I Shares, which were first offered on 10/3/97,
      is based on the historical performance of the Fund's Class A Shares,
      including the performance of the predecessor fund and commingled accounts
      (without sales charge) prior to that date. The predecessor fund and
      commingled accounts were managed using substantially the same investment
      objective, policies and methodologies as the Fund.

(4)   Merrill Lynch 1-12 Year Municipal Bond Index, an unmanaged index generally
      representative of municipal bonds with intermediate maturities of no less
      than one year and no more than twelve years. The Index is for reference
      only, does not mirror the Fund's investments, and reflects no deduction
      for fees, expenses or taxes.

      The table shows the impact of taxes on the Fund's returns. The Fund's
      after-tax returns are calculated using the highest individual federal
      marginal income tax rates and do not reflect the impact of state and local
      taxes. In certain cases, the figure representing "Return After Taxes on
      Distributions and Sale of Fund Shares" may be higher than the other return
      figures for the same period. A higher after-tax return results when a
      capital loss occurs upon redemption and translates into an assumed tax
      deduction that benefits the shareholder. Please note that actual after-tax
      returns depend on an investor's tax situation and may differ from those
      shown. Also note that after-tax returns shown are not relevant to
      investors who hold their Fund shares through tax-deferred arrangements,
      such as 401(k) plans or individual retirement accounts.

(1)   AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2)   Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase. See "Distribution Arrangements."

(3)   For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B Shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares.

(4)   To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

(5)   Other expenses for the AmSouth Fund are being limited to 0.50% for Class A
      shares, 050% for Class B shares and 0.35% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time.

(6)   The Pioneer Fund's total annual operating expenses in the table have not
      been reduced by any expense offset arrangements.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's gross operating
expenses remain the same. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Tennessee Tax-Exempt Fund. The Trustees considered the
following matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

      Second, after the Reorganization, the combined Fund will have an asset
size substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

      Third, the historical investment performance of Pioneer Tax Free Income
Fund is better than your AmSouth Fund's investment performance. For the one,
five and ten year periods ended December 31, 2004, Class A shares of Pioneer Tax
Free Income Fund had an average annual return of 0.05% (one year); 5.66% (five
years); and 5.88% (ten years) compared to an average annual return of the Class
A shares of your AmSouth Fund of -2.87% (one year); 3.96% (five years); and
4.22% (ten years), respectively, during the same period. The trustees also
considered performance information provided for the one, three, and five year
periods ended March 31, 2005 during which Class A shares of Pioneer Tax Free
Income Fund had an average annual return of 3.30% (one year); 5.82% (three
years); and 6.10% (five years), compared to an average annual return of the
Class A shares of your AmSouth Fund of -0.81% (one year); 3.52% (three years);
and 4.21% (five years), respectively, during

                                       14



the same period. In addition, the Trustees considered the track record of
Pioneer in managing equity and fixed income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $2 billion in municipal securities. Pioneer is part of the
global asset management group of UniCredito Italiano S.p.A., one of the largest
banking groups in Italy, providing investment management and financial services
to mutual funds, institutional and other clients. As of December 31, 2004,
assets under management of UniCredito Italiano S.p.A. were approximately $175
billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

     Fifth, the Pioneer Fund's management fee is lower than your Fund's
management fee and will benefit from breakpoints as assets increase as a result
of the Reorganization. The aggregate Rule 12b-1 distribution and shareholder
servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A
and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's
Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the
Pioneer Fund's Class Y shares. The net and gross expenses of Class A, Class B
and Class Y shares of Pioneer Tax Free Income Fund are currently lower than the
gross and net expenses of the corresponding classes of your Fund and are
estimated to be lower on a pro forma basis after giving effect to the
Reorganization.

     Sixth, although the Pioneer Tax Free Income Fund does not concentrate its
investments in Tennessee and the dividends on the Pioneer Fund will not be
exempt from Tennessee state taxes, your Board believes that the broader
investment focus of the Pioneer Fund offered better long term prospects and
potential for after tax return.

     Seventh, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and expenses of the AmSouth Fund in connection with the Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005.The table also sets
forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth High Quality Municipal Bond Fund approve
the reorganization of their fund into Pioneer Tax Free Income Fund.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

      The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

                          The Fund uses a "first-in, first-out" method
                          to determine how long you have held your
                          shares. This means that if you purchased
                          shares on different days, the shares purchased
                          first will be considered redeemed first for

                          made through retirement plan, brokerage and

                          Fund will not impose the redemption fee on a

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

      o     Interest rates increase, causing the value of investments to
            decline, a risk that is generally high for longer-term bonds and low
            for shorter-term bonds

      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay principal earlier than scheduled,
            forcing the Fund to reinvest in lower yielding securities. This is
            known as call or prepayment risk

      o     Interest rates decrease and the Fund's income declines. Income risk
            is generally high for shorter-term bonds and low for longer-term
            bonds

                                        8



      o     The average life of certain types securities are extended because of
            slower than expected principal during periods of rising interest
            rates. This may lock in a below market interest rate, increase the
            security's duration (the estimated period until the security is paid
            in full) and reduce the value of the security. This is known as
            extension risk

      o     The adviser's judgment about the attractiveness, relative value or
            potential appreciation of a particular sector, security or
            investment strategy proves to be incorrect

      AmSouth Government Income Fund is subject to risks relating to the fact
that it is non-diversified. The Fund may invest in a small number of companies
which may increase the volatility of the Fund. Accordingly, the Fund's portfolio
may be more sensitive to changes in the market value of a single company or
industry.

time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

(1)   After-tax returns are calculated using the historical highest individual
      federal marginal income tax rates and do not reflect the impact of state
      and local taxes. Actual after-tax returns depend on your situation and may
      differ from those shown. Furthermore, the after-tax returns shown are not
      relevant to those who hold their shares through tax-deferred arrangements
      such as 401(k) plans or IRA accounts, or to investors that are tax-exempt.

(2)   The Lehman Brothers Government Bond Index is an unmanaged measure of the
      performance of U.S. Treasury debt, all publicly issued debt of U.S.
      government agencies and quasi-federal corporations, and corporate debt
      guaranteed by the U.S. government. The Lehman Brother Government Bond
      Index is for reference only, does not mirror the Fund's investments, and
      reflects no deduction for fees, expenses or taxes.

(3)   Class Y shares were not outstanding prior to the closing of the
      Reorganization and consequently have no performance history. However, the
      performance record of the Class Y shares would be modestly higher than the
      performance of the Class A and Class B shares due to the lower expenses
      applicable to Class Y shares.

(4)   The Lehman Brothers Fixed Rate Mortgage-Backed Securities Index, an
      unmanaged index including 15- and 30-year fixed rate securities backed by
      mortgage pools of the Government National Mortgage Association ("GNMA"),
      Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National
      Mortgage Association ("FNMA"). The Lehman Brother Fixed Rate
      Mortgage-Backed Securities Index is for reference only, does not mirror
      the Fund's investments, and reflects no deduction for fees, expenses or
      taxes.

The Funds' Fees and Expenses

      Shareholders of both Funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay if
you were to buy and hold shares of each Fund. The expenses in the tables
appearing below are based on (i) for the AmSouth Government Income Fund, the
expenses of AmSouth Government Income Fund for the period ended January 31, 2005
and (ii) for Pioneer America Income Trust, the expenses of Pioneer America
Income Trust for the period ended December 31, 2004. Future expenses for all
share classes may be greater or less. The tables also show the pro forma
expenses of the combined Fund assuming the Reorganization occurred on December
31, 2004.

(1) AmSouth Bank or other financial institutions may charge their customer
    account fees for automatic investment and other cash management services
    provided in connection with investment in the Fund.

(2) Sales charges may be reduced depending upon the amount invested or, in
    certain circumstances, waived. Class A shares of the Pioneer Fund bought as
    part of an investment of $1 million or more are not subject to an initial
    sales charge, but may be charged a CDSC of 1.00% if sold within one year of
    purchase.

(3) For Class B shares purchased prior to the combination of AmSouth Funds with
    ISG Funds, the CDSC on such Class B shares held continuously declines over
    six years, starting with year one and ending in year seven from: 4%, 3%, 3%,
    2%, 2%, 1%. For all other Class B shares held continuously, the CDSC
    declines over six years, starting with year one and ending in year seven
    from: 5%, 4%,

                                       12



    3%, 3%, 2%, 1%. Approximately eight years after purchase (seven years in the
    case of shares acquired in the ISG combination), Class B shares
    automatically convert to Class A shares.

(4) To discourage short-term trading, a redemption fee of 2.00% will be charged
    on sales or exchanges of Class A, Class B and Class I shares of your AmSouth
    Fund made within 7 days of the date of purchase. A wire transfer fee of
    $7.00 will be deducted from the amount of your redemption if you request a
    wire transfer.

(5) Other expenses for your AmSouth Fund are being limited to 0.51% for Class A
    shares, 0.51% for Class B shares and 0.36% for Class I shares. Any fee
    waiver or expense reimbursement arrangement is voluntary and may be
    discontinued at any time.

(6) The Pioneer Fund's total annual operating expenses in the table have not
    been reduced by any expense offset arrangements.

(7) The expenses in the table above reflect the expense limitations currently in
    effect for the Pioneer Fund, under which Pioneer has contractually agreed to
    limit ordinary operating expenses to the extent required to reduce Fund
    expenses to 1.30%, and 2.20% of the average daily net assets attributable to
    Class A and Class B shares, respectively. These expense limitations are in
    effect through April 1, 2008 for Class A shares and through April 1, 2006
    for Class B shares. There can be no assurance that Pioneer will extend the
    expense limitations beyond such time.

(8) Class Y shares of Pioneer America Income Trust will be offered for the first
    time in connection with the closing of the Reorganization.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, and (e) the expense limitation for your Fund is in effect for
year one. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Government Income Fund. The Trustees considered the
following matters, among others, in approving the proposal.

                                       13



     First, AAMI, the investment adviser to you AmSouth Fund, and AmSouth Bank
informed the Trustees that they did not intend to continue to provide investment
advisory services to the AmSouth Funds. Consequently, a change in your AmSouth
Fund's investment adviser was necessary. In the absence of the Reorganization,
such a change would be more likely to motivate shareholders invested in reliance
on AAMI's role to withdraw from the Fund, thereby reducing fund size and
increasing fund expense ratios.

     Second, the historical investment performance of Pioneer America Income
Trust is comparable to your AmSouth Fund's investment performance. For the one,
five and ten year periods ended December 31, 2004, Class A shares of Pioneer
America Income Trust had an average annual return of -1.86% (one year); 5.26%
(five year); and 5.75% (ten year), compared to an average annual return of the
Class A shares of your AmSouth Fund of -1.72% (one year); 5.12% (five year); and
6.06% (ten year), respectively, during the same period. The Trustees also
considered performance information provided for the one, three, and five year
periods ended March 31, 2005 during which Class A shares of Pioneer America
Income Trust had an average annual return of 0.79% (one year); 4.42% (three
year); and 5.57% (five year) compared to an average annual return of the Class A
shares of your AmSouth Fund of 0.02% (one year); 3.99% (three year); and 5.40%
(five year), respectively, during the same period. In addition, the Trustees
considered the track record of Pioneer in managing equity and fixed income
mutual funds.

     Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over
80 investment companies and accounts with approximately $42 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutional and other
clients. As of December 31, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 80 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your AmSouth Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer America Income Trust's management fee (0.50% of average
daily net assets) is the same as the advisory fee of your Fund (0.50% of average
daily net assets). In addition, the Trustees considered that the broader
distribution arrangements of the Pioneer Fund offer greater potential for
further asset growth and reduce per share expenses. The aggregate Rule 12b-1
distribution and shareholder servicing fees and non-Rule 12b-1 shareholder
servicing fees paid by the Class A and Class B shares of both Funds are the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that is not paid by the Pioneer Fund's Class Y shares. Currently,
for each class of shares, your Fund's gross expenses are higher than the
corresponding class of the Pioneer Fund. However, net of expense limitations,
the expenses attributable to Class Y shares of the Pioneer Fund are lower than
your Fund's net expenses attributable to Class I shares and the net expenses of
the Pioneer Fund attributable to Class A and Class B shares are higher than the
net expenses of the corresponding classes of the AmSouth Fund. On a pro forma
basis, after giving effect to the Reorganization, it is estimated that the gross
expenses of each class of the Pioneer America Income Trust will be lower than
the gross expenses of the corresponding class of your Fund. It is also estimated
that the expenses of the Pioneer America Income Trust's Class Y shares net of
expense limitations will be lower than the net expenses of your Fund's Class I
shares but that the net expenses of the Pioneer America Income Trust's Class A
shares and Class B shares will be higher. The lower net expenses are a result of
expense limitations on your AmSouth Fund that are voluntary and may be
discontinued at any time. AAMI has informed the trustees that the expense
limitations will be discontinued in the future. The trustees considered the
positive factors associated with the Reorganization, such as greater fund assets
and potential for growth, to outweigh the negative factors, such as the increase
in expenses.

     Fifth, the Class A, B and Y shares of Pioneer America Income Trust received
in the Reorganization will provide AmSouth Government Income Fund shareholders
with exposure to substantially the same investment product as they currently
have.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible for all
costs and

                                       14



expenses of your Fund in connection with the Reorganization. The Trustees also
considered that Pioneer and AmSouth Bank will benefit from the Reorganization.
See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations."

      The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

      The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

      o     The possibility that an issuer cannot make timely interest and
            principal payments on its debt securities. The lower a security's
            rating, generally the greater its credit risk.

      o     During periods of declining interest rates, the issuer of a security
            may exercise its option to prepay principal earlier than scheduled,
            forcing the Fund to reinvest in lower yielding securities. This is
            known as call or prepayment risk.

      o     During periods of rising interest rates, the average life of certain
            types of securities may be extended because of slower than expected
            principal payments. This may lock in a below market interest rate,
            increase the security's duration (the estimated period until the
            security is paid in full) and reduce the value of the security. This
            is known as extension risk. Risk is generally high for longer-term
            bonds and lower or for shorter-term bonds.

      o     The adviser's judgment about the attractiveness, relative value or
            potential appreciation of a particular sector, security or hedging
            strategy proves to be incorrect.

      Certain securities issued by agencies and instrumentalities of the U.S.
government in which each Fund may invest are backed by the full faith and credit
of the U.S. government, but others are not insured or guaranteed by the U.S.
government and may be supported only by the issuer's right to borrow from the
U.S. Treasury, by the credit of the issuing agency, instrumentality or
corporation, or by the U.S. in some other way. Likewise, government sponsored
entities such as the Federal Home Loan Mortgage Corporation (Freddie Mac), FNMA
and the FHLBs, although chartered or sponsored by Congress, are not funded by
congressional appropriations and the debt and mortgage backed securities issued
by them are neither guaranteed nor issued by the U.S. government.

      To the extent that Pioneer Short Term Income Fund invests significantly in
asset-backed and mortgage-related securities, its exposure to prepayment and
extension risks may be greater than other investments in fixed income
securities.

      Pioneer Short Term Income Fund may be subject to the following additional
risks associated with investing in non-U.S. issuers, which may involve unique
risks compared to investing in securities of U.S. issuers. These risks are more
pronounced to the extent the Fund invests in issuers in countries with emerging
markets or if the Fund invests significantly in one country. These risks may
include:

      o     Less information about non-U.S. issuers or markets may be available
            due to less rigorous disclosure or accounting standards or
            regulatory practices

      o     Many non-U.S. markets are smaller, less liquid and more volatile. In
            a changing market, the adviser/subadviser might not be able to sell
            the Fund's portfolio securities at times, in amounts and at prices
            it considers reasonable

      o     Adverse effect of currency exchange rates or controls on the value
            of the Fund's investments

      o     The economies of non-U.S. countries may grow at slower rates than
            expected or may experience a downturn or recession

      o     Economic, political and social developments may adversely affect the
            securities markets

      o     Withholding and other non-U.S. taxes may decrease the Fund's return

                                       10



      In addition, at times, more than 25% of Pioneer Short Term Income Fund's
assets may be invested in the same market segment, such as financials or
technology. To the extent the Fund emphasizes investments in a market segment,
the Fund will be subject to a greater degree to the risks particular to the
industries in that segment, and may experience greater market fluctuation, than
a fund without the same focus.

Past Performance

      Set forth below is performance information for your AmSouth Fund. The bar
charts show how your AmSouth Fund's total return (not including any deduction
for sales charges) has varied from year to year for each full calendar year. The
tables show average annual total return (before and after taxes) for your
AmSouth Fund over time for each class of shares (including deductions for sales
charges) compared with a broad-based securities market index. The bar charts
give an indication of the risks of investing in each Fund, including the fact
that you could incur a loss and experience volatility of returns year to year.
Past performance before and after taxes does not indicate future results.

(1)   Class A shares were first offered on 2/1/89.

(2)   Performance for the Class B shares, which were first offered on 1/21/99,
      is based on the historical performance of the Fund's Class A shares
      (without sales charge) prior to that date. The historical performance of
      the Class B shares has been restated to reflect the Fund's Class B shares
      distribution (12b-1) fees and the CDSC.

(3)   Performance for the Class I shares, which were first offered on 9/2/97, is
      based on the historical performance of the Fund's Class A shares,
      including the performance of the predecessor fund and commingled accounts
      (without sales charge) prior to that date. The predecessor fund and
      commingled accounts were managed using substantially the same investment
      objective, policies and methodologies as the Fund.

(4)   Merrill Lynch 1-5 Year Government/Corporate Bond Index, an unmanaged index
      representative of the total return of short-term government and corporate
      bonds, is for reference only, does not mirror the Fund's investments, and
      reflects no deduction for fees, expenses or taxes.

The table above shows the impact of taxes on AmSouth Limited Term Bond Fund's
returns. After-tax returns are only shown for Class A shares and Class I shares
and may vary for Class B shares. The Fund's after-tax returns are calculated
using the highest individual federal marginal income tax rates and do not
reflect the impact of state and local taxes. In certain cases, the figure
representing "Return After Taxes on Distributions and Sale of Fund Shares" may
be higher than the other return figures for the same period. A higher after-tax
return results when a capital loss occurs upon redemption and translates into an
assumed tax deduction that benefits the shareholder. Please note that actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. Also note that after-tax returns shown are not relevant to
shareholders who hold Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts.

The Funds' Fees and Expenses

      Shareholders of both Funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay if
you were to buy and hold shares of each Fund. The expenses in the tables
appearing below are based on (i) for the AmSouth Limited Term Bond Fund, the
expenses of AmSouth Limited Term Bond Fund for the period ended January 31, 2005
and (ii) for Pioneer Short Term Income Fund, the expenses of Pioneer Short Term
Income Fund for the period ended February 28, 2005. Future expenses for all
share classes may be greater or less. Shareholders of AmSouth Limited Term Bond
Fund are also being asked to approve the reorganization of their Fund into
Pioneer Short Term Income Fund. The tables also show the pro forma expenses of
the combined Fund assuming the Reorganization occurred on February 28, 2005.

(1.)  AmSouth Bank or other financial institutions may charge their customer
      account fees for automatic investment and other cash management services
      provided in connection with investment in the Fund.

(2.)  Sales charges may be reduced depending upon the amount invested or, in
      certain circumstances, waived. Class A shares of the Pioneer Fund bought
      as part of an investment of $1 million or more are not subject to an
      initial sales charge, but may be charged a CDSC of 1.00% if sold within
      one year of purchase.

(3.)  For Class B shares purchased prior to the combination of AmSouth Funds
      with ISG Funds, the CDSC on such Class B shares held continuously declines
      over six years, starting with year one and ending in year seven from: 4%,
      3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the
      CDSC declines over six years, starting with year one and ending in year
      seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven
      years in the case of shares acquired in the ISG combination), Class B
      shares automatically convert to Class A shares.

(4.)  To discourage short-term trading, a redemption fee of 2.00% will be
      charged on sales or exchanges of Class A, Class B and Class I shares of
      your AmSouth Fund made within 7 days of the date of purchase. A wire
      transfer fee of $7.00 will be deducted from the amount of your redemption
      if you request a wire transfer.

                                       13



(5.)  Other expenses for your AmSouth Fund are being limited to 0.49% for Class
      A shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee
      waiver or expense reimbursement arrangement is voluntary and may be
      discontinued at any time.

(6.)  The expenses in the table above reflect the expense limitation in effect
      through December 31, 2005 under which Pioneer has contractually agreed not
      to impose all or a portion of its management fee and, if necessary, to
      limit other ordinary operating expenses to the extent required to reduce
      Class A expenses to 0.90% of the average daily net assets attributable to
      Class A shares. The portion of Fund expenses (including the amount of
      management fee waived) attributable to Class B and Class Y shares will be
      reduced only to the extent such expenses are reduced for Class A shares.
      Any differences in the fee waiver and expense limitation among classes
      result from rounding in the daily calculation of a class' net assets and
      expense limitation, which may exceed 0.01% annually. There can be no
      assurance that Pioneer will extend the expense limitation beyond December
      31, 2005.

The hypothetical example below helps you compare the cost of investing in each
Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods
shown, (b) you reinvest all dividends and distributions, (c) your investment has
a 5% return each year, and (d) each Fund's gross operating expenses remain the
same. The examples are for comparison purposes only and are not a representation
of either Fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Limited Term Bond Fund and its shareholders. The Trustees
considered the following matters, among others, in approving the proposal.

      First, AAMI, the investment adviser to your AmSouth Fund informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

      Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets, including $15.7 billion in fixed income securities. Pioneer is part of
the

                                       14



global asset management group of UniCredito Italiano S.p.A., one of the largest
banking groups in Italy, providing investment management and financial services
to mutual funds, institutional and other clients. As of December 31, 2004,
assets under management of UniCredito Italiano S.p.A. were approximately $175
billion worldwide. Shareholders of your AmSouth Fund would become part of a
significantly larger family of funds that offers a more diverse array of
investment options and enhanced shareholder account options. The Pioneer family
of mutual funds offers over 80 funds, including domestic and international
equity and fixed income funds and a money market fund that will be available to
your AmSouth Fund's shareholders through exchanges.

     Third, Pioneer Short Term Income Fund's management fee (0.40% of average
daily net assets) is lower than the advisory fee of your AmSouth Fund (0.50% of
average daily net assets). The distribution and shareholder servicing fees paid
by the Class A and Class B shares of both Funds are the same. Moreover, your
AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is
not paid by the Pioneer Fund's Class Y shares. While Pioneer Short Term Income
Fund's gross and net expenses are higher than the historical gross and net
expenses of your AmSouth Fund, (with the exception of the Pioneer Fund's Class Y
shares) on a pro forma basis, after giving effect to the Reorganization, the
gross and net expenses of each class of the Pioneer Fund are estimated to be
lower than gross and net expenses of the corresponding class of your Fund. In
addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduce per share expenses.

     Fourth, the Class A, B and Y shares of Pioneer Short Term Income Fund
received in the Reorganization will provide AmSouth Limited Term Bond Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth
Funds in connection with the Reorganization. AAMI will otherwise be responsible
for all costs and expenses of the AmSouth Funds in connection with the
Reorganization.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      The following table sets forth the capitalization of each Fund as of May

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

is that AmSouth Treasury Reserve Money Market Fund invests primarily in U.S.
Treasury securities and related repurchase agreements, while Pioneer Cash
Reserves Fund invests in a broader range of high quality short-term instruments.
In the table below, if a row extends across the entire table, the policy
disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

      Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. The
Pioneer Fund may be subject to greater credit risk than the AmSouth Fund because
it may invest in securities other than U.S. Government securities. You could
lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

      o     Interest rates go up, causing the value of the Fund's investments to
            decline

      o     In the case of Pioneer Cash Reserves Fund, the issuer of a security
            owned by the Fund may not be able to make timely payments because of
            a general economic downturn or increased governmental costs

      o     The adviser's judgment about the credit quality, attractiveness or
            relative value of a particular security proves to be incorrect

      Pioneer Cash Reserves Fund may be subject to the following additional
risks associated with investing in non-U.S. issuers, which may involve unique
risks compared to investing in securities of U.S. issuers. These risks are more
pronounced to the extent the Fund invests in issuers in countries with emerging
markets or if the Fund invests significantly in one country. These risks may
include:

      o     Inadequate financial information

      o     Smaller, less liquid and more volatile markets

      o     Political and economic upheavals

      Pioneer Cash Reserves does not concentrate its investments in any
industry. At times, more than 25% of the Pioneer Cash Reserves Fund's assets may
be invested in the same market segment, such as financials. To the extent the
Fund emphasizes investments in a market segment, the Fund will be subject to a
greater degree to the risks particular to the industries in that segment, and
may experience greater market fluctuation, than a fund without the same focus.
For example, industries in the financial segment, such as banks, insurance
companies, broker-dealers and REITs, may be sensitive to changes in interest
rates and general economic activity and are subject to extensive government
regulation.

Past Performance

      Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return has varied from year to year for each full
calendar year. The tables show average annual total return for each Fund over
time for each class of shares compared with a broad-based securities market
index. The bar charts give an indication of the risks of

                                       6



investing in each Fund, including the fact that you could incur a loss and
experience volatility of returns year to year. Past performance does not
indicate future results.

(1)   The return reported above assumes the reinvestment of dividends. The
      AmSouth Treasury Reserve Money Market Fund commenced operations on 3/29/94
      through a transfer of assets from certain collective trust fund
      ("commingled") accounts managed by AAMI, using substantially the same
      investment objective, polices and methodologies as the Fund. The quoted
      performance of the Fund includes the performance of the commingled
      accounts for the periods prior to the Fund's

      commencement of operations, restated to reflect the expenses associated
      with the Fund. The commingled accounts were not registered with the SEC
      and were not subject to the investment restrictions imposed by law on
      registered mutual funds. If the commingled accounts had been registered,
      their returns may have been adversely affected. Class A Shares were first
      offered on 8/29/94.

(1)   Return before taxes assumes that you sell your Class A shares at the end
      of the period and that you reinvest all of your dividends and
      distributions.

(2)   Class Y shares were not outstanding prior to the closing of the
      Reorganization and consequently have no performance history. However, the
      performance record of the Class Y shares would be modestly higher than the
      performance of the Class A and Class B shares due to the lower expenses
      applicable to Class Y shares.

      (1)   AmSouth Bank or other financial institutions may charge their
            customer account fees for automatic investment and other cash
            management services provided in connection with investment in the
            Fund.

      (2)   A wire transfer fee of $7.00 will be deducted from the amount of
            your redemption if you request a wire transfer.

      (3)   Other expenses for your AmSouth Fund are being limited to 0.30% for
            Class A shares and 0.25% for Class I shares. Any fee waiver or
            expense reimbursement arrangement is voluntary and may be
            discontinued at any time.

      (4)   The Pioneer Fund's total annual operating expenses in the table have
            not been reduced by any expense offset arrangements.

      (5)   Pioneer has agreed to limit the Fund's expenses or waive a portion
            of its management fee to maintain a net asset value of $1.00. Under
            certain circumstances, this limitation may result in a 0.00% yield
            for one or more classes for shares. From time to time, Pioneer and
            its affiliates may limit the expenses of one or more classes for the
            purpose of increasing its yield during the period of the limitation.
            These expense limitation policies are voluntary and temporary and
            may be revised or terminated by Pioneer at any time without notice.

      (6)   Other expenses for Class Y shares are estimated based on expenses
            that would have been incurred for the fiscal year ended December 31,
            2004 had such shares been outstanding for the entire fiscal year.

      (7)   Class Y shares of Pioneer Cash Reserves Fund are being offered for
            the first time in connection with the Reorganization.

      The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's operating expenses remain
the same and (e) you sell your shares at the end of the time period shown. The
examples are for comparison purposes only and are not a representation of either
Fund's actual expenses or returns, either past or future.

      * Pursuant to a separate proposal, AmSouth Prime Money Market Fund
      proposes to transfer its assets to Pioneer Cash Reserves Fund.

Reasons for the Proposed Reorganization

      The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Treasury Reserve Money Market Fund and its shareholders.
The Trustees considered the following matters, among others, in approving the
proposal.

      First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

                                       10



     Second, after the Reorganization, the combined Fund will have an asset size
substantially larger than that of your AmSouth Fund, which may allow the
combined Fund to achieve significant economies of scale in investments or
expenses.

     Third, the historical investment performance of Pioneer Cash Reserves Fund
is comparable to your AmSouth Fund's investment performance. For the one, five
and ten year periods ended December 31, 2004, Class A shares of Pioneer Cash
Reserves Fund had an average annual return of 0.45% (one year); 2.12% (five
year); and 3.42% (ten year) compared to an average annual return of the Class A
shares of your AmSouth Fund of 0.61% (one year); 2.15% (five year); and 3.47%
(ten year), respectively, during the same period. In addition, the Trustees
considered the track record of Pioneer in managing fixed income mutual funds.

     Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges.

     Fifth, Pioneer Cash Reserves Fund's management fee (0.40% of average daily
net assets) is the same as the advisory fee of your AmSouth Fund (0.40% of
average daily net assets). Although the historical net expenses of Pioneer Cash
Reserves Fund are higher than your AmSouth Fund's historical net expenses, the
estimated pro forma gross expenses of the Pioneer Fund after giving effect to
the Reorganization are lower than your AmSouth Fund's gross expenses. In
addition, with respect to Class Y shares, the pro forma expense of the Pioneer
Fund, net of expense limitations, are lower than your Fund's net expenses
attributable to Class I shares. The net expenses attributable to the Class A
shares of the Pioneer Fund on a pro forma basis are estimated to be two basis
points higher than the net expenses attributable to the Class A shares of the
AmSouth Fund. However, AAMI has informed the trustees that its expense
limitations will be discontinued in the future. The distribution and shareholder
servicing fees paid by the Class A and Class B shares of both Funds are the
same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder
servicing fee that is not paid by the Pioneer Fund's Class Y shares. In
addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduce per share expenses.

     Sixth, the substantially larger size of Pioneer Cash Reserves Fund offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.

     Seventh, the Class A and Y shares of Pioneer Cash Reserves Fund received in
the Reorganization will provide AmSouth Treasury Reserve Money Market Fund
shareholders with exposure to substantially the same investment product as they
currently have. The Board considered the differences in the investment policies
of the two Funds and concluded that the broader investment range of Pioneer Cash
Reserves Fund did not materially increase the risk exposure to AmSouth Treasury
Reserve Money Market Fund shareholders.

     Eighth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth
Funds in connection with the Reorganization. AAMI will otherwise be responsible
of all costs and expenses of the AmSouth Funds in connection with the
Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

      The following table sets forth the capitalization of each Fund as of May
31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also
sets forth the pro forma capitalization of the combined Fund as of May 31, 2005,
assuming the shareholders of AmSouth Prime Money Market Fund approve the
reorganization of their fund into Pioneer Cash Reserves Fund.

      It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

      For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

      The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

Comparison of Principal Risks of Investing in the Funds

   Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. Even
though each Fund seeks to maintain a constant net asset value of $1.00, you
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

o  Interest rates go up, causing the value of the Fund's investments to decline
o  The issuer of a security owned by the Fund may not be able to make timely
   payments because of a general economic downturn or increased governmental
   costs
o  The adviser's judgment about the credit quality, attractiveness or relative
   value of a particular security proves to be incorrect

   Pioneer Cash Reserves Fund may be subject to the following additional risks
associated with investing in non-U.S. issuers, which may involve unique risks
compared to investing in securities of U.S. issuers. These risks are more
pronounced to the extent the Fund invests in issuers in countries with emerging
markets or if the Fund invests significantly in one country. These risks may
include:

o  Inadequate financial information
o  Smaller, less liquid and more volatile markets
o  Political and economic upheavals

   Pioneer Cash Reserves does not concentrate its investments in any industry.
At times, more than 25% of the Pioneer Cash Reserves Fund's assets may be
invested in the same market segment, such as financials. To the extent the Fund
emphasizes investments in a market segment, the Fund will be subject to a
greater degree to the risks particular to the industries in that segment, and
may experience greater market fluctuation, than a fund without the same focus.
For example, industries in the financial segment, such as banks, insurance
companies, broker-dealers and REITs, may be sensitive to changes in interest
rates and general economic activity and are subject to extensive government
regulation.

Past Performance

   Set forth below is performance information for each Fund. The bar charts show
how each Fund's total return (not including any deduction for sales charges) has
varied from year to year for each full calendar year. The tables show average
annual total return (before and after taxes) for each Fund over time for each
class of shares (including deductions for sales charges) compared with a
broad-based securities market index. The bar charts give an indication of the
risks of investing in each Fund, including the fact that you could incur a loss
and experience volatility of returns year to year. Past performance before and
after taxes does not indicate future results. No Class Y shares of Pioneer Cash
Reserves Fund are currently outstanding.

(1)  Return before taxes assumes that you sell your Class A shares at the end of
     the period and that you reinvest all of your dividends and distributions.

(2)  Return before taxes assumes that you sell your Class B shares at the end of
     the period and that you reinvest all of your dividends and distributions.

(3)  Class Y shares were not outstanding prior to the closing of the
     Reorganization and consequently have no performance history. However, the
     performance record of the Class Y shares would be modestly higher than the
     performance of the Class A and Class B shares due to the lower expenses
     applicable to Class Y shares.

(1)  AmSouth Bank or other financial institutions may charge their customer
     account fees for automatic investment and other cash management services
     provided in connection with investment in the Fund.

(2)  For former Class B shares purchased prior to the combination of AmSouth
     Funds with ISG Funds, the CDSC on such Class B shares held continuously
     declines over six years, starting with year one and ending in year seven
     from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held
     continuously, the CDSC declines over six years, starting with year one and
     ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after
     purchase (seven years in the case of shares acquired in the ISG
     combination), Class B shares automatically convert to Class A shares.

(3)  A wire transfer fee of $7.00 will be deducted from the amount of your
     redemption if you request a wire transfer.

(4)  Other expenses for your AmSouth Fund are being limited to 0.40% for Class A
     shares, 0.20% for Class B shares and 0.25% for Class I shares. Any fee
     waiver or expense reimbursement arrangement is voluntary and may be
     discontinued at any time.

(5)  The Pioneer Fund's total annual operating expenses in the table have not
     been reduced by any expense offset arrangements.

(6)  Pioneer has agreed to limit the Fund's expenses or waive a portion of its
     management fee to maintain a net asset value of $1.00. Under certain
     circumstances, this limitation may result in a 0.00% yield for one or more
     classes for shares. From time to time, Pioneer and its affiliates may limit
     the expenses of one or more classes for the purpose of increasing its yield
     during the period of the limitation. These expense limitation policies are
     voluntary and temporary and may be revised or terminated by Pioneer at any
     time without notice.

                                       11


(7)  Other expenses for Class Y shares are estimated based on expenses that
     would have been incurred for the fiscal year ended December 31, 2004 had
     such shares been outstanding for the entire fiscal year.

(8)  Class Y shares of Pioneer Cash Reserves Fund are being offered for the
     first time in connection with the Reorganization.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, and (d) each Fund's operating expenses
remain the same. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Prime Money Market Fund and its shareholders. The Trustees
considered the following matters, among others, in approving the proposal.

     First, AAMI, the investment adviser to your AmSouth Fund, informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the historical investment performance of Pioneer Cash Reserves Fund
is comparable to your AmSouth Fund's investment performance. For example, the
one, five and ten year periods ended December 31, 2004, Class A shares of
Pioneer Cash Reserves Fund had an average annual return of 0.45% (one year);
2.12% (five year); and 3.42% (ten year) compared to an average annual return of
the Class A shares of your AmSouth Fund of 0.60% (one year); 2.20% (five year);
and 3.56% (ten year), respectively, during the same period. In addition, the
Trustees considered the track record of Pioneer in managing equity and fixed
income mutual funds.

     Third, the resources of Pioneer. At December 31, 2004, Pioneer manages over
80 investment companies and accounts with approximately $42 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutional and other
clients. As of December 31, 2004, assets under management of UniCredito Italiano
S.p.A. were

                                       13


approximately $175 billion worldwide. Shareholders of your AmSouth Fund would
become part of a significantly larger family of funds that offers a more diverse
array of investment options and enhanced shareholder account options. The
Pioneer family of mutual funds offers over 80 funds, including domestic and
international equity and fixed income funds and a money market fund that will be
available to your AmSouth Fund's shareholders through exchanges.

     Fourth, Pioneer Cash Reserves Fund's management fee (0.40% of average daily
net assets) is the same as the advisory fee of your AmSouth Fund (0.40% of
average daily net assets). The gross expenses of each class of the Pioneer Fund,
on both a historical and pro-forma basis, are lower than the gross expenses
attributable to the corresponding class of your Fund. Expenses, net of
limitations, on a pro forma basis for the Class A and Class Y shares of the
Pioneer Fund are lower than the net expenses of the corresponding Class of your
Fund. With respect to Class B shares, your Fund's historical net expenses are
lower than the pro-forma expenses attributable to the Class B shares of the
Pioneer Fund. The pro forma expenses of Class B shares net of limitations will
increase 84 basis points. The lower net expenses on your AmSouth Fund are a
result of voluntary expense limitations that may be discontinued at any time.
AmSouth Bank and its affiliates have informed the trustees that they will
discontinue their expense limitations in the future. The trustees considered the
positive factors associated with the Reorganization, such as greater fund assets
and potential for growth, to outweigh the negative factors, such as the increase
in net expenses for the Class B shares. The aggregate Rule 12b-1 distribution
and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees
paid by the Class A and Class B shares of both Funds are the same. Moreover,
your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee
that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader
distribution arrangements of the Pioneer Fund offer greater potential for
further asset growth and reduce per share expenses.

     Fifth, the substantially larger size of the combined Pioneer Cash Reserves
Fund will offer greater opportunity for diversification of the investment
portfolio, which should help to reduce risks.

     Sixth, the Class A, B and Y shares of Pioneer Cash Reserves Fund received
in the Reorganization will provide AmSouth Prime Money Market Fund shareholders
with exposure to substantially the same investment product as they currently
have.

     Seventh, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth
Funds in connection with the Reorganization. AAMI will otherwise be responsible
for all costs and expenses of the AmSouth Funds in connection with the
Reorganizations.

     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY

     The following is a summary of more complete information appearing later in
    this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1, because it contains details
that are not in the summary.

     Each Fund is a money market fund that may invest in high quality short-term
instruments that are exempt from regular federal income tax. Consequently, the
policies and risks of each Fund are similar. A portion of the income from
Pioneer Tax Free Money Market Fund may be a preference item for purposes of the
federal alternative minimum tax. In the table below, if a row extends across the
entire table, the policy disclosed applies to both your AmSouth Fund and the
Pioneer Fund.

                             When selecting securities for the Fund's
                             portfolio, AAMI first considers safety of
                             principal and the quality of an investment.
                             AAMI then focuses on generating a high level
                             of income. AAMI generally evaluates
                             investments based on interest rate
                             sensitivity selecting those securities whose
                             maturities fit the Fund's interest rate
                             sensitivity target and which AAMI believes to
                             be the best relative values.

                             The Fund will maintain an average weighted
                             portfolio maturity of 90 days or less and
                             will limit the maturity of each security in
                             its portfolio to 397 days or less.

Comparison of Principal Risks of Investing in the Funds

   Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. Even
though each Fund seeks to maintain a $1 share price, you could lose money on
your investment in either Fund or not make as much as if you invested elsewhere
if:

   o  Interest rates go up, causing the value of the Fund's investments to
      decline

   o  New federal or state legislation adversely affects the tax-exempt status
      of securities held by the Fund or the financial ability of an issuer to
      repay financial obligations

   o  The issuer of a security owned by the Fund may not be able to make timely
      payments because of a general economic downturn or increased governmental
      costs

   o  The adviser's judgment about the credit quality, attractiveness or
      relative value of a particular security proves to be incorrect

   Fund's highest quarterly return was 0.94% for the quarter ended June 30,

   Pursuant to an agreement and plan of reorganization, Pioneer Tax Exempt Money
Market Fund acquired all of the assets and those liabilities reflected in the
net assets of Safeco Tax-Free Money Free Money Market Fund (the predecessor
fund) on December 10, 2004. In the reorganization, the predecessor fund
exchanged all of its assets for Investor Class shares of the Pioneer Fund. The
predecessor fund offered an Investor Class and other classes of shares similar
to the Fund's Class A, B and C shares. As a result of the reorganization,
Pioneer Tax Exempt Money Market Fund is the accounting successor of the
predecessor fund. The predecessor fund operated as a registered investment
company like the Fund. The performance of each class of the Fund includes the
performance of the predecessor fund's Class A and Class B shares prior to the
reorganization, which has been restated to reflect differences in any applicable
sales charges. If all the expenses of Pioneer Tax Exempt Money Market Fund were
reflected, the performance would be lower. Since August 2, 2004, Pioneer has
served as the predecessor fund's investment adviser. Safeco Asset Management,
Inc. previously served as the predecessor fund's investment adviser. The Fund's
Investor Class shares are not offered in the reorganization.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Tax-Exempt Money Market Fund and its shareholders. The
Trustees considered the following matters, among others, in approving the
proposal.

     First, AAMI, the investment adviser to your AmSouth Fund informed the
Trustees that it does not intend to continue to provide investment advisory
services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's
investment adviser was necessary. In the absence of the Reorganization, such a
change would be more likely to motivate shareholders invested in reliance on
AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing
fund expense ratios.

     Second, the long-term historical investment performance of Pioneer Tax Free
Money Market Fund is superior to your AmSouth Fund's investment performance. For
the one and five year periods ended December 31, 2004, Class A shares of Pioneer
Tax Free Money Market Fund had an average annual return of 0.47% (one year) and
6.99% (five year), compared to an average annual return of the Class A shares of
your AmSouth Fund of 0.56% (one year) and 1.35% (five year), respectively,
during the same period. In addition, the Trustees considered the track record of
Pioneer in managing equity and fixed income mutual funds.

     Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over
80 investment companies and accounts with approximately $42 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutional and other
clients. As of December 31, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 80 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your AmSouth Fund's shareholders through exchanges.

     Fourth, Pioneer Tax Free Money Market Fund's management fee (0.40% of
average daily net assets) is the same as the advisory fee of your AmSouth Fund
(0.40% of average daily net assets). The historical expenses attributable to the
Class A shares of the Pioneer Fund are higher than your Fund's Class A shares,
on both a gross and net basis. On a pro forma basis, the gross expenses of the
Pioneer Fund attributable to Class A expenses are estimated to be lower than
your Fund's gross expenses; however, your Fund's net expenses attributable to
Class A expenses are estimated to be lower than the pro forma net expenses
attributable to Class A shares. However, AAMI has advised your Trustees that it
will discontinue the expense limitation in the future. With respect to Class Y
shares, the pro forma gross and net expenses of the Pioneer Fund are lower than
the gross and net expenses of the Class I shares of your Fund. The aggregate
Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1
shareholder servicing fees paid by the Class A and Class B shares of both Funds
are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1
shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares.
In addition, the broader distribution arrangements of the Pioneer Fund offer
greater potential for further asset growth and reduced per share expenses.

     Fifth the Class A shares of Pioneer Tax Free Money Market Fund received in
the Reorganization will provide AmSouth Tax-Exempt Money Market Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Sixth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth
Funds in connection with the Reorganization. AAMI will otherwise be responsible
of all costs and expenses of the AmSouth Funds in connection with the
Reorganization.

                                       11


     The Trustees also considered that Pioneer and AmSouth Bank will benefit
from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

Comparison of Principal Risks of Investing in the Funds

   Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. Even
though each Fund seeks to maintain a $1 share price, you could lose money on
your investment in either Fund or not make as much as if you invested elsewhere
if:

   o  Interest rates go up, causing the value of the Fund's investments to
      decline

   o  The issuer of a security owned by the Fund defaults on its obligation to
      pay principal and/or interest or has its credit rating downgraded

   o  The adviser's judgment about the credit quality, attractiveness or
      relative value of a particular security proves to be incorrect

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of AmSouth Institutional Prime Obligations Money Market Fund. The
Trustees considered the following matters, among others, in approving the
proposal.

     First, AAMI, the investment adviser to the Fund, informed the Trustees that
it does not intend to continue to provide investment advisory services to the
AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser
was necessary. In the absence of the Reorganization, such a change would be more
likely to motivate shareholders invested in reliance on AAMI's role to withdraw
from the Fund, thereby reducing fund size and increasing fund expense ratios.

     Second, the resources of Pioneer. At December 31, 2004, Pioneer managed
over 80 investment companies and accounts with approximately $42 billion in
assets. Pioneer is part of the global asset management group of UniCredito
Italiano S.p.A., one of the largest banking groups in Italy, providing
investment management and financial services to mutual funds, institutional and
other clients. As of December 31, 2004, assets under management of UniCredito
Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your
AmSouth Fund would become part of a significantly larger family of funds that
offers a more diverse array of investment options and enhanced shareholder
account options. The Pioneer family of mutual funds offers over 80 funds,
including domestic and international equity and fixed income funds and a money
market fund that will be available to your AmSouth Fund's shareholders through
exchanges. In addition, Pioneer offers shareholders additional options for their
accounts, including the ability to transact and exchange shares over the
telephone or online and the ability to access account values and transaction
history in all of the shareholder's direct accounts in the Pioneer Funds over
the telephone or online.

     Third, Pioneer Institutional Money Market Fund's management fee (0.20% of
average daily net assets) will be the same as the advisory fee of your Fund
(0.20% of average daily net assets). The aggregate Rule 12b-1 distribution and
shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by
both Funds will be the same. The gross


                                       10


expenses of each class of the Pioneer Fund are estimated to be lower than the
gross expenses of the corresponding class of the AmSouth Fund. Net of expense
limitations, the expenses of the Class 1 and Class 3 shares of the Pioneer Fund
are estimated to be the same as net expenses of the corresponding class of the
AmSouth Fund. The estimated net expenses of the Class 2 shares of the Pioneer
Fund are estimated to be one basis point higher than the net expenses of the
Class 2 shares of the AmSouth Fund. AAMI has informed the trustees that the
expense limitations will be discontinued in the future.

     Fourth, the Institutional Class 1, Institutional Class 2 and Institutional
Class 3 shares of Pioneer Fund received in the Reorganization will provide
AmSouth Institutional Prime Obligations Money Market Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Fifth, the transaction is structured to qualify as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986 and
therefore will not be treated as a taxable sale of your AmSouth shares.

     Pioneer and AmSouth Bank will pay all costs of preparing and printing the
Funds' proxy statements and solicitation costs incurred by the Funds in
connection with the Reorganization. AAMI will otherwise be responsible of all
costs and expenses of AmSouth Fund in connection with the Reorganizations. The
Trustees also considered that Pioneer and AmSouth Bank will benefit from the
Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the
Reorganizations."

     The Board of Trustees of the Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that a fund normally incurs when purchasing securities. This opportunity
provides an economic benefit to the Pioneer Fund and its shareholders.

     It is impossible to predict how many shares of the Pioneer Fund will
actually be received and distributed by your AmSouth Fund on the Reorganization
date. The table should not be relied upon to determine the amount of the Pioneer
Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your AmSouth Fund.
Similarly, the Board of Trustees of the Pioneer Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of the Pioneer Fund.

                                       11


     The Trustees recommend that the shareholders of your AmSouth Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.


                                       12


               TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION

The Reorganizations

   o  Each Reorganization is scheduled to occur at 4:00 p.m., Eastern time, on [
      ], 2005, unless your AmSouth Fund and the corresponding Pioneer Fund agree
      in writing to a later date. Your AmSouth Fund will transfer all of its
      assets to the corresponding Pioneer Fund. The corresponding Pioneer Fund
      will assume your AmSouth Fund's liabilities that are included in the
      calculation of your AmSouth Fund's net asset value on the Closing Date.
      The net asset value [of both Funds] will be computed as of 4:00 p.m.,
      Eastern time, on the Closing Date.

   o  Each Pioneer Fund (other than Pioneer Institutional Money Market Fund)
      will issue to the corresponding AmSouth Fund Class A, B and Y shares with
      an aggregate net asset value equal to the net assets attributable to the
      corresponding AmSouth Fund's Class A, B and I shares. These shares will
      immediately be distributed to your AmSouth Fund's shareholders in
      proportion to the relative net asset value of their holdings of your
      AmSouth Fund's shares on the Closing Date. As a result, each AmSouth
      Fund's shareholders will end up as Class A, B, or Y class shareholders of
      the corresponding Pioneer Fund.

   o  In the case of Pioneer Institutional Money Market Fund, Class 1, 2 and 3
      shares will be distributed in exchange for Institutional Class 1, 2 and 3
      shares of AmSouth Institutional Prime Obligations Money Market Fund. These
      shares will immediately be distributed to AmSouth Institutional Prime
      Obligations Money Market Fund's shareholders in proportion to the relative
      net asset value of their holdings of AmSouth Institutional Prime
      Obligations Money Market Fund's shares on the Closing Date. As a result,
      AmSouth Institutional Prime Obligations Money Market Fund's shareholders
      will end up as Class 1, 2 or 3 shareholders of Pioneer Institutional Money
      Market Fund.

   o  After the distribution of shares, your AmSouth Fund will be liquidated and
      dissolved.

   o  Each Reorganization is intended to result in no income, gain or loss being
      recognized for federal income tax purposes and will not take place unless
      both Funds involved in the Reorganization receive a satisfactory opinion
      concerning the tax consequences of the Reorganization from Wilmer Cutler
      Pickering Hale and Dorr LLP, counsel to the Pioneer Funds.

Agreement and Plan of Reorganization

   The shareholders of each AmSouth Fund are being asked to approve an Agreement
and Plan of Reorganization substantially in the form attached as EXHIBIT A-1 or
A-2 (each, a "Plan"). The description of the Plan contained herein is qualified
in its entirety by the attached copies, as appropriate.

   Conditions to Closing each Reorganization. The obligation of each Fund to
consummate each Reorganization is subject to the satisfaction of certain
conditions, including each Fund's performance of all of its obligations under
the Plan, the receipt of certain documents and financial statements from your
AmSouth Fund and the receipt of all consents, orders and permits necessary to
consummate the Reorganization (see Sections 7 and 8 of the Plan). The
consummation of each Reorganization is not contingent on consummation of any
other Reorganization.

   The obligations of both Funds are subject to the approval of the Plan by the
necessary vote of the outstanding shares of your AmSouth Fund, in accordance
with the provisions of AmSouth Funds' trust instrument and by-laws. The Funds'
obligations are also subject to the receipt of a favorable opinion of Wilmer
Cutler Pickering Hale and Dorr LLP as to the United States federal income tax
consequences of each Reorganization (see Section 8.5 of the Plan).

   Termination of the Plan. The board of either the AmSouth Funds or the
corresponding Pioneer Fund may terminate the Plan (even if the shareholders of
your AmSouth Fund have already approved it) at any time before the Closing Date,
if that board believes in good faith that proceeding with the Reorganization
would no longer be in the best interests of shareholders.

                                       9


                        TAX STATUS OF EACH REORGANIZATION

   Each Reorganization is intended to result in no income, gain or loss being
recognized for United States federal income tax purposes and will not take place
unless both Funds involved in the Reorganization receive a satisfactory opinion
from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Pioneer Funds,
substantially to the effect that each Reorganization will be a "reorganization"
within the meaning of Section 368(a) of the Code.

   As a result, for federal income tax purposes:

   o  No gain or loss will be recognized by your AmSouth Fund upon (1) the
      transfer of all of its assets to the corresponding Pioneer Fund as
      described in this Proxy Statement/Prospectus or (2) the distribution by
      your AmSouth Fund of Pioneer Fund shares to your AmSouth Fund's
      shareholders;

   o  No gain or loss will be recognized by the corresponding Pioneer Fund upon
      the receipt of your AmSouth Fund's assets solely in exchange for the
      issuance of Pioneer Fund shares to your AmSouth Fund and the assumption of
      your AmSouth Fund's liabilities by the Pioneer Fund;

   o  The basis of the assets of your AmSouth Fund acquired by the corresponding
      Pioneer Fund will be the same as the basis of those assets in the hands of
      your AmSouth Fund immediately before the transfer;

   o  The tax holding period of the assets of your AmSouth Fund in the hands of
      the corresponding Pioneer Fund will include your AmSouth Fund's tax
      holding period for those assets;

   o  You will not recognize gain or loss upon the exchange of your shares of
      your AmSouth Fund solely for the Pioneer Fund shares as part of the
      Reorganization;

   o  The basis of the Pioneer Fund shares received by you in the Reorganization
      will be the same as the basis of your shares of your AmSouth Fund
      surrendered in the exchange; and

   o  The tax holding period of the Pioneer Fund shares you receive will include
      the tax holding period of the shares of your AmSouth Fund surrendered in
      the exchange, provided that you held the shares of your AmSouth Fund as
      capital assets on the date of the exchange.

   In rendering such opinions, counsel shall rely upon, among other things,
reasonable assumptions as well as representations of your AmSouth Fund and the
Pioneer Fund (see the annexes to the Plan).

   No tax ruling has been or will be received from the Internal Revenue Service
("IRS") in connection with the Reorganizations. An opinion of counsel is not
binding on the IRS or a court, and no assurance can be given that the IRS would
not assert, or a court would not sustain, a contrary position.

   You should consult your tax adviser for the particular tax consequences to
you of the Reorganizations, including the applicability of any state, local or
foreign tax laws.


                                       10


                        VOTING RIGHTS AND REQUIRED VOTE

   Each share of your AmSouth Fund is entitled to one vote and each fractional
share shall be entitled to a proportionate fractional vote. A quorum is required
to conduct business at the Meeting. With respect to each AmSouth Fund, the
presence in person or by proxy of a majority of the outstanding shares of an
AmSouth Fund entitled to cast votes at the Meeting will constitute a quorum with
respect to that AmSouth Fund. A favorable vote of a "majority of the outstanding
voting securities" of the applicable AmSouth Fund is required to approve each
Proposal. Under the Investment Company Act, the vote of a majority of the
outstanding voting securities means the affirmative vote of the lesser of (i)
67% or more of the shares of the applicable AmSouth Fund represented at the
meeting, if at least 50% of all outstanding shares of the AmSouth Fund are
represented at the meeting, or (ii) 50% or more of the outstanding shares of the
AmSouth Fund entitled to vote at the meeting.

     COMPARISON OF DELAWARE STATUTORY TRUST AND MASSACHUSETTS BUSINESS TRUST

   The AmSouth Funds are series of a Massachusetts Business Trust. Most of the
Pioneer Funds are series of Delaware Statutory Trusts. The following is a
summary of the principal differences between Delaware Statutory Trusts and
Massachusetts Business Trusts.

Limitation of Shareholders' and Series' Liability

   Delaware law provides that the shareholders of a Delaware statutory 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
the shareholders of Europe Fund) may, under certain circumstances, be liability
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, Delaware law affords grater protection
against potential shareholder liability. Similarly, Delaware law provides that,
to the extent that a Delaware statutory 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 a Massachusetts
business trust. While the trustees believe that a series of 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 statutory trust or a shareholder thereof) for any
act, omission or obligation of the statutory trust or any trustee thereof.
Delaware law also provides that a trustee's actions under a Delaware statutory
trust's declaration of trust or by-laws will not subject the trustee to
liability to the statutory trust or its shareholders if the trustee takes such
action in good faith reliance on the provisions of the statutory trust's
declaration of trust or bylaws. The declaration of trust of a Massachusetts
business trust may limit the liability of a trustee, who is not also an officer
of the corporation, for breach of fiduciary duty except for, among other things,
any act or omission not in good faith which involves

                                       11


intentional misconduct or a knowing violation of law or any transaction from
which such trustee derives an improper direct or indirect financial benefit. The
trustees believe that such limitations on liability under Delaware law and under
the Pioneer Funds' declarations of trust are consistent with those applicable to
directors of a corporation under Delaware law and will be beneficial in
attracting and retaining in the future qualified persons to act as trustees.

Shareholder Voting

   Delaware law provides that a Delaware statutory 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, as amended (the "1940 Act"), votes on certain matters by
trustees would still need to be taken at actual in-person meetings.

Board Composition

   Delaware law explicitly provides that separate boards of trustees may be
authorized for each series of a Delaware statutory trust. Whether separate
boards of trustees can be authorized for series of a Massachusetts business
trust is unclear under Massachusetts law. As always, the establishment of any
board of trustees of a registered investment company must comply with applicable
securities laws, including the provision of the 1940 Act regarding the election
of trustees by shareholders. Establishing separate boards of trustees would,
among other things, enable the series of a Delaware statutory trust to be
governed by individuals who are more familiar with such series' particular
operations.

                 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS

Investment Adviser

   Pioneer serves as the investment adviser to each Pioneer Fund. Pioneer is an
indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the
largest banking groups in Italy. Pioneer is part of the global asset management
group providing investment management and financial services to mutual funds,
institutions and other clients. As of December 31, 2004, assets under management
were approximately $175 billion worldwide, including over $42 billion in assets
under management by Pioneer. Pioneer's main office is at 60 State Street,
Boston, Massachusetts 02109. Pioneer's U.S. mutual fund investment history
includes creating one of the first mutual funds in 1928.

   The Board of Trustees of the Pioneer Funds is responsible for overseeing the
performance of each of Pioneer Fund's investment adviser and subadviser, if any,
and determining whether to approve and renew the fund's investment advisory
agreement and the subadvisory agreements.

   Pioneer has received an order (the "Exemptive Order") from the SEC that
permits Pioneer, subject to the approval of the Pioneer Funds' Board of
Trustees, to hire and terminate a subadviser or to materially modify an existing
subadvisory agreement for a Pioneer Fund without shareholder approval. Pioneer
retains the ultimate responsibility to oversee and recommend the hiring,
termination and replacement of any subadviser. To the extent that the SEC adopts
a rule that would supersede the Exemptive Order, Pioneer and the Pioneer Funds
intend to rely on such rule to permit Pioneer, subject to the approval of the
Pioneer Funds' Board of Trustees and any other applicable conditions of the
rule, to hire and terminate a subadviser or to materially modify an existing
subadvisory agreement for a Pioneer Fund without shareholder approval.

Buying, Exchanging and Selling Shares of the Pioneer Funds

   Net Asset Value. Each Pioneer 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 Pioneer 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 Pioneer Fund generally values its portfolio securities using closing
market prices or readily available market quotations. When closing market prices
or market quotations are not available or are considered by Pioneer to be

Pioneer Fund will use a security's fair value. Fair value is the valuation of a
security determined on the basis of factors other than market value in
accordance with procedures approved by the Pioneer Funds' trustees. Each Pioneer
Fund also may use the fair value of a security, including a non-U.S. security,
when Pioneer determines that the closing market price on the primary exchange
where the security is traded no longer accurately reflects the value of the
security due to factors affecting one or more relevant securities markets or the
specific issuer. The use of fair value pricing by a Pioneer Fund may cause the
net asset value of its shares to differ from the net asset value that would be
calculated using closing market prices. International securities markets may be
open on days when the U.S. markets are closed. For this reason, the value of any
international securities owned by a Pioneer Fund could change on a day you
cannot buy or sell shares of the fund. Each Pioneer Fund may use a pricing
service or a pricing matrix to value some of its assets. Debt securities with
remaining maturities of 60 days or less are valued at amortized cost, which is a
method of determining a security's fair value.

   Pioneer International Core Equity Fund primarily invests in securities of
non-U.S. issuers and the markets for these securities generally close prior to
the time the Fund determines its net asset value. However, the value of these
securities continues to be influenced by changes in the global markets.
Consequently, the trustees have determined to use the fair value of these
securities as of the time the fund determines its net asset value, based upon
data from a pricing service. On a daily basis, the pricing service recommends
changes, based upon a proprietary model, to the closing market prices of each
non-U.S. security held by the fund to reflect the security's fair value at the
time the fund determines its net asset value. The fund applies these
recommendations in accordance with procedures approved by the trustees. A
security's fair value determined in this manner may differ from the security's
closing market price on the date the fund determines its net asset value or the
opening price of the security on the next business day. The fund's use of this
method may significantly affect its net asset value compared to the net asset
value that would have been determined using closing market prices. The fund also
may take other factors influencing specific markets or issuers into
consideration in determining the fair value of a non-U.S. security.

   You buy or sell shares at the share price. When you buy Class A shares, you
pay an initial sales charge unless you qualify for a waiver or reduced sales
charge. However, the Class A shares of the Pioneer Funds you receive in the
Reorganizations will not be subject to any sales charge. When you buy Class B
shares, you do not pay an initial sales charge but impose a contingent deferred
sales charge. However, if you sell within five years of purchase, you will pay a
contingent deferred sales charge. The Class B shares of the Pioneer Funds you
receive in the transaction will be subject to the same contingent deferred sales
charge as your Class B shares of the AmSouth Funds held at the time of sale.
These shares would then convert to Class A shares eight years after the original
date of purchase. Class Y shares do not impose a sales charge.

   Opening Your Account. If your shares are held in your investment firm's name,
the options and services available to you may be different from those described
herein or in the Pioneer Fund's prospectus. Ask your investment professional for
more information.

   If you invest in a Pioneer Fund through investment professionals or other
financial intermediaries, including wrap programs and fund supermarkets,
additional conditions may apply to your investment in a Pioneer Fund, and the
investment professional or intermediary may charge you a transaction-based or
other fee for its services. These conditions and fees are in addition to those
imposed by the Pioneer Fund and its affiliates. You should ask your investment
professional or financial intermediary about its services and any applicable
fees.

   Account Options. Use your account application to select options and
privileges for your account. You can change your selections at any time by
sending a completed account options form to the transfer agent. You may be
required to obtain a signature guarantee to make certain changes to an existing
account.

   Call or write to the Pioneer Funds' transfer agent for account applications,
account options forms and other account information:

PIONEER INVESTMENT MANAGEMENT SHAREHOLDER SERVICES, INC.
P.O. Box 55014
Boston, Massachusetts 02205-5014
Telephone 1-800-225-6292

   Telephone Transaction Privileges. If your account is registered in your name,
you can buy, exchange or sell shares of the Pioneer Funds by telephone. If you
do not want your account to have telephone transaction privileges, you must
indicate that choice on your account application or by writing to the transfer
agent.

                                       13


   When you request a telephone transaction the transfer agent will try to
confirm that the request is genuine. The transfer agent records the call,
requires the caller to provide the personal identification number for the
account and sends you a written confirmation. Each Pioneer Fund may implement
other confirmation procedures from time to time. Different procedures may apply
if you have a non-U.S. account or if your account is registered in the name of
an institution, broker-dealer or other third party.

   Online Transaction Privileges. If your account is registered in your name,
you may be able to buy, exchange or sell fund shares online. Your investment
firm may also be able to buy, exchange or sell your Pioneer Fund shares online.

   To establish online transaction privileges complete an account options form,
write to the transfer agent or complete the online authorization screen on:
www.pioneerfunds.com.

   To use online transactions, you must read and agree to the terms of an online
transaction agreement available on the Pioneer website. When you or your
investment firm requests an online transaction the transfer agent electronically
records the transaction, requires an authorizing password and sends a written
confirmation. The Pioneer Funds may implement other procedures from time to
time. Different procedures may apply if you have a non-U.S. account or if your
account is registered in the name of an institution, broker-dealer or other
third party. You may not be able to use the online transaction privilege for
certain types of accounts, including most retirement accounts.

   Share Price. If you place an order with your investment firm before the New
York Stock Exchange closes and your investment firm submits the order to PFD
prior to PFD's close of business (usually 5:30 p.m. Eastern time), your share
price will be calculated that day. 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 Pioneer Fund Shares. You may buy shares of each Pioneer Fund from any
investment firm that has a sales agreement with PFD. 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 shares of the Pioneer Funds 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. 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. The minimum investment amount does not
apply for purposes of the Reorganization.

   Exchanging Pioneer Fund Shares. You may exchange your shares in a Pioneer
Fund 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. Each Pioneer 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 policy as described in each fund's prospectus.

   Selling Pioneer Fund Shares. Your shares will be sold at net asset value per
share next calculated after the Pioneer Fund, or authorized agent, and as a
broker-dealer, receives your request in good order. If the shares you are
selling are subject to a deferred sales charge, it will be deducted from the
sale proceeds. Each Pioneer Fund generally will send your sale proceeds by
check, bank wire or electronic funds transfer. Normally you will be paid within
seven days. If you are selling shares from a non-retirement account or certain
IRAs, you may use any of the methods described below. If you are selling shares
from a retirement account other than an IRA, you must make your request in
writing.

   You may have to pay federal income taxes on a sale or an exchange.

                                       14

                   When you request a telephone or online purchase,
                   the transfer agent will electronically debit the
                   amount of the purchase from your bank account of
                   record. The transfer agent will purchase Pioneer
                   Fund shares for the amount of the debit at the
                   offering price determined after the transfer agent
                   receives your telephone or online purchase
                   instruction and good funds. It usually takes three
                   business days for the transfer agent to receive

                   available in the amount of your investment.

Pioneer Fund Shareholder Account Policies

   Signature Guarantees and Other Requirements. You are required to obtain a
signature guarantee when you are:

   o  Requesting certain types of exchanges or sales of Pioneer Fund shares

   o  Redeeming shares for which you hold a share certificate

                                       16


   o  Requesting certain types of changes for your existing account

   You can obtain a signature guarantee from most broker-dealers, banks, credit
unions (if authorized under state law) and federal savings and loan
associations. You cannot obtain a signature guarantee from a notary public. All
Pioneer Funds will accept only medallion signature guarantees. A medallion
signature guarantee may be obtained from a domestic bank or trust company,
broker, dealer, clearing agency, savings association, or other financial
institution that is participating in a medallion program recognized by the
Securities Transfer Association. Signature guarantees from financial
institutions that are not participating in one of these programs are not
accepted. Fiduciaries and corporations are required to submit additional
documents to sell Pioneer Fund shares.

   Exchange Limitation. You may only make up to four exchange redemptions of
$25,000 or more per account per calendar year out of a Pioneer Fund. Each Fund's
exchange limitation is intended to discourage short-term trading in fund shares.
Short-term trading can increase the expenses incurred by the Fund and make
portfolio management less efficient. In determining whether the exchange
redemption limit has been reached, Pioneer may aggregate a series of exchanges
(each valued at less than $25,000) and/or fund accounts that appear to be under
common ownership or control. Pioneer may view accounts for which one person
gives instructions or accounts that act on advice provided by a single source to
be under common control.

   The exchange limitation does not apply to automatic exchange transactions or
to exchanges made by participants in employer-sponsored retirement plans
qualified under Section 401(a) of the Code. While financial intermediaries that
maintain omnibus accounts that invest in the fund are requested to apply the
exchange limitation policy to shareholders who hold shares through such
accounts, we do not impose the exchange limitation policy at the level of the
omnibus account and are not able to monitor compliance by the financial
intermediary with this policy.

   Redemption Fee. Pioneer International Core Equity Fund has adopted a
redemption fee on short term holdings of the Fund's shares. If you sell or
exchange shares within 30 days of any purchase of Fund shares, the Fund will
apply a 2% fee to the entire amount of your sales proceeds. The Fund's
redemption fee is intended to discourage short-term trading in fund shares.
Short-term trading can increase the expenses incurred by the fund and make
portfolio management less efficient.

   Excessive Trading. Frequent trading into and out of the fund can disrupt
portfolio management strategies, harm fund performance by forcing the fund to
hold excess cash or to liquidate certain portfolio securities prematurely and
increase expenses for all investors, including long-term investors who do not
generate these costs. An investor may use short-term trading as a strategy, for
example, if the investor believes that the valuation of the fund's portfolio
securities for purposes of calculating its net asset value does not fully
reflect the then current fair market value of those holdings. The fund
discourages, and does not take any intentional action to accommodate, excessive
and short-term trading practices, such as market timing. Although there is no
generally applied standard in the marketplace as to what level of trading
activity is excessive, we may consider trading in the fund's shares to be
excessive for a variety of reasons, such as if:

   o  You sell shares within a short period of time after the shares were
      purchased;
   o  You make two or more purchases and redemptions within a short period of
      time;
   o  You enter into a series of transactions that is indicative of a timing
      pattern or strategy; or
   o  We reasonably believe that you have engaged in such practices in
      connection with other mutual funds.

   The fund's Board of Trustees has adopted policies and procedures with respect
to frequent purchases and redemptions of fund shares by fund investors. Pursuant
to these policies and procedures, we monitor selected trades on a daily basis in
an effort to detect excessive short-term trading. If we determine that an
investor or a client of a broker has engaged in excessive short-term trading
that we believe may be harmful to the fund, we will ask the investor or broker
to cease such activity and we will refuse to process purchase orders (including
purchases by exchange) of such investor, broker or accounts that we believe are
under their control. In determining whether to take such actions, we seek to act
in a manner that is consistent with the best interests of the fund's
shareholders.

   While we use our reasonable efforts to detect excessive trading activity,
there can be no assurance that our efforts will be successful or that market
timers will not employ tactics designed to evade detection. If we are not
successful, your return from an investment in the fund may be adversely
affected. Frequently, fund shares are held through omnibus accounts maintained
by financial intermediaries such as brokers and retirement plan administrators,
where the holdings of multiple

                                       17


shareholders, such as all the clients of a particular broker, are aggregated.
Our ability to monitor trading practices by investors purchasing shares through
omnibus accounts is limited and dependent upon the cooperation of the financial
intermediary in observing the fund's policies.

   In addition to monitoring trades, the policies and procedures provide that:

   o  The fund imposes limitations on the number of exchanges out of an account
      holding the fund's Class A, Class B or Class C shares that may occur in
      any calendar year.

   o  Certain funds managed by Pioneer have adopted redemption fees that are
      incurred if you redeem shares within a short period after purchase,
      including exchanges. These redemption fees are described in the applicable
      prospectuses under "Fees and expenses."

   o  The fund may reject a purchase or exchange order before its acceptance or
      an order prior to issuance of shares. The fund may also restrict
      additional purchases or exchanges in an account. Each of these steps may
      be taken, for any reason, without prior notice, including transactions
      that the fund believes are requested on behalf of market timers. The fund
      reserves the right to reject any purchase request by any investor or
      financial institution if the fund believes that any combination of trading
      activity in the account or related accounts is potentially disruptive to
      the fund. A prospective investor whose purchase or exchange order is
      rejected will not achieve the investment results, whether gain or loss,
      that would have been realized if the order were accepted and an investment
      made in the fund. The fund and its shareholders do not incur any gain or
      loss as a result of a rejected order. The fund may impose further
      restrictions on trading activities by market timers in the future. The
      fund's prospectus will be amended or supplemented to reflect any material
      additional restrictions on trading activities intended to prevent
      excessive trading.

   Minimum Account Size. Each Pioneer 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 Pioneer 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 Pioneer Fund by
telephone during times of market volatility or disruption in telephone service.
If you are unable to reach the Pioneer 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. If you are legally required
to obtain a certificate, you may request one for your Class A shares only. A fee
may be charged for this service. Any share certificates of the AmSouth Funds
outstanding at the Closing of the Reorganization will be deemed to be cancelled
and will no longer represent shares of the Funds.

   Other Policies. Each Pioneer Fund may suspend transactions in shares when
trading on the New York Stock Exchange is closed or restricted, when an
emergency exists that makes it impracticable, as determined by the SEC, for the
fund to sell or value its portfolio securities or with the permission of the
SEC.

   Each Pioneer Fund or PFD may revise, suspend or terminate the account options
and services available to shareholders at any time.

   Each Pioneer Fund reserves the right to redeem in kind by delivering
portfolio securities to a redeeming shareholder, provided that the Pioneer Fund
must pay redemptions in cash if a shareholder's aggregate redemptions in a 90
day period are less than $250,000 or 1% of the fund's net assets.

Dividends and Capital Gains

   Each Pioneer Fund generally pays any distributions of net short- and
long-term capital gains and dividends from any net investment income at least
annually.

                                       18


   Each Pioneer Fund may also pay dividends and capital gain distributions at
other times if necessary for the fund to avoid U.S. federal income or excise
tax. If you invest in a Pioneer Fund close to the time that the fund makes a
distribution, generally you will pay a higher price per share and you will pay
taxes on the amount of the distribution whether you reinvest the distribution or
receive it as cash.

Taxes

   For U.S. federal income tax purposes, distributions from each Pioneer Fund's
net long-term capital gains (if any) are considered long-term capital gains and
may be taxable to you at different maximum rates depending upon their source and
other factors. Short-term capital gain distributions for each Pioneer Fund are
taxable as ordinary income.

   Dividends from net investment income are taxable either as ordinary income
or, if so designated by the fund and certain other conditions, including holding
period requirements, are met by the fund and the shareholder, as "qualified
dividend income" taxable to individual shareholders at the maximum 15% U.S.
federal tax rate. Dividends and distributions generally are taxable, whether you
take payment in cash or reinvest them to buy additional Pioneer Fund shares.

   When you sell or exchange Pioneer Fund shares you will generally recognize a
capital gain or capital loss in an amount equal to the difference between the
net amount of sale proceeds (or, in the case of an exchange, the fair market
value of the shares) that you receive and your tax basis for the shares that you
sell or exchange. In January of each year each Pioneer Fund will mail to you
information about your dividends, distributions and any 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 Pioneer Fund will withhold 28% "backup
withholding" tax from your dividends and distributions, sale proceeds and any
other payments to you.

   You should ask your tax adviser about any federal, state and foreign tax
considerations, including possible additional withholding taxes for non-U.S.
shareholders. You may also consult the "Tax Status" section of each Pioneer
Fund's statement of additional information for a more detailed discussion of
U.S. federal income tax considerations, including qualified dividend income
considerations that may affect the Pioneer Fund and its shareholders.

   Pioneer Funds' Rule 12b-1 Plans. As described above, each Pioneer Fund has
adopted a Rule 12b-1 plan for its Class A shares, Class B shares, Class 2 shares
and Class 3 shares (the "Plans"). Because the Rule 12b-1 fees payable under each
Plan are an ongoing expense, over time they may increase the cost of your
investment and your shares may cost more than shares that are not subject to a
distribution or service fee or sales charge.

   Compensation and Services. Each Class A Plan is a reimbursement plan, and
distribution expenses of PFD are expected to substantially exceed the
distribution fees paid by the fund in a given year. Pursuant to each Class A
Plan the fund reimburses PFD for its actual expenditures to finance any activity
primarily intended to result in the sale of Class A shares or to provide
services to holders of Class A shares, provided the categories of expenses for
which reimbursement is made are approved by the board of trustees. The expenses
of the fund pursuant to the Class A Plan are accrued daily at a rate which may
not exceed the annual rate of 0.25% of the fund's average daily net assets
attributable to Class A shares.

   The Class B Plan provides that the fund shall pay to PFD, as the fund's
distributor for its Class B shares a distribution fee equal on an annual basis
to 0.75% of the fund's average daily net assets attributable to Class B shares
and a service fee equal to 0.25% of the fund's average daily net assets
attributable to Class B shares. The distribution fee compensates PFD for its
distribution services with respect to Class B shares. PFD also pays commissions
to broker-dealers and the cost of printing prospectuses and reports used for
sales purposes and the preparation and printing of sales literature and other
distribution-related expenses. The plan authorizes PFD to pay a service fee to
broker-dealers at a rate of up to 0.25% of the fund's average daily net assets
attributable to Class B shares owned by shareholders for whom that broker-dealer
is the holder or dealer of record. This service fee compensates the
broker-dealer for providing personal services and/or account maintenance
services rendered by the broker-dealer with respect to Class B shares.

   The Class 2 and Class 3 Plans (which pertain only to Pioneer Institutional
Money Market Fund) provide that the fund will pay PFD, as the distributor of the
shares, a distribution and service fee accrued daily and paid quarterly, equal
on an annual

                                       19


basis to 0.25% of the fund's average daily net assets attributable to Class 2
shares and 0.50% of the fund's average daily net assets attributable to Class 3
shares. These plans authorize PFD to pay securities dealers or other service
organizations who agree to provide certain services to investors holding Class 1
and Class 2 shares a service fee of up to 0.25% of the fund's average daily net
assets attributable to shares held by such investors. The plans also may
compensate PFD for its distribution services with respect to these shares of the
fund.

   The Class B, Class 2 and Class 3 Plans are compensation plans, which provide
for a fixed level of fees. Payments under these plans are not tied exclusively
to actual distribution and service expenses, and may exceed (or may be less
than) the expenses actually incurred.

   Trustee Approval and Oversight. Each Plan was last approved by the board of
trustees of each Pioneer Fund, including a majority of the independent trustees,
by votes cast in person at meetings called for the purpose of voting on the Plan
on December 2, 2004 (July 12, 2005 with respect to the Class 1 and Class 2 Plans
for Pioneer Institutional Money Market Fund). Pursuant to the Plan, at least
quarterly, PFD will provide each fund with a written report of the amounts
expended under the Plan and the purpose for which these expenditures were made.
The trustees review these reports on a quarterly basis to determine their
continued appropriateness.

   Term, Termination and Amendment. Each Plan's adoption, terms, continuance and
termination are governed by Rule 12b-1 under the Investment Company Act. The
board of trustees believes that there is a reasonable likelihood that the Plans
will benefit each fund and its current and future shareholders. The Plans may
not be amended to increase materially the annual percentage limitation of
average net assets which may be spent for the services described therein without
approval of the shareholders of the fund affected thereby, and material
amendments of the Plans must also be approved by the trustees as provided in
Rule 12b-1.

                              FINANCIAL HIGHLIGHTS

   The following tables show the financial performance of each Pioneer Fund for
the past five fiscal years and, if applicable, for any recent semiannual period
(or the period during which each Pioneer Fund has been in operation, if less
than five years). Certain information reflects financial results for a single
Pioneer Fund share. "Total return" shows how much an investment in a Pioneer
Fund would have increased or decreased during each period, assuming you had
reinvested all dividends and other distributions. In the case of each Pioneer
Fund, each fiscal year ended on or after the fiscal year ended June 30, 2002 has
been audited by Ernst & Young LLP, each Pioneer Fund's independent registered
public accounting firm, as stated in their reports incorporated by reference in
this registration statement. For fiscal years prior to the fiscal year ended
June 30, 2002, the financial statements of each Pioneer Fund were audited by
Arthur Andersen LLP, the Pioneer Funds' previous independent accountants. Arthur
Andersen ceased operations in 2002. The information for any semiannual period
has not been audited.

(a) As a result of a change in accounting principle, the effect due to mandatory
    accretion of discounts and amortization of premiums on debt securities
    resulted in a reduction of net investment income of $0.02 per share, an

    decreased by 0.18%.

(a) On January 1, 2001, the Trust began accreting discounts and amortizing
    premiums on debt securities. The effect of this changes for the year ended
    December 31, 2001, was to decrease net investment income by $0.01 per share,
    increase net realized and unrealized gain (loss) by $0.01 per share and
    decrease the ratio of net investment income to average net assets assuming
    waiver of management fees by PIM and reduction for fees paid indirectly from
    4.42% to 4.25%. Per share ratios and supplemental data for periods prior to
    January 1, 2001, have not been restated to reflect this change in
    presentation.

                       INFORMATION CONCERNING THE MEETING

Solicitation of Proxies

   In addition to the mailing of these proxy materials, proxies may be solicited
by telephone, by fax or in person by the trustees and officers of your AmSouth
Fund or its affiliates, including personnel of your AmSouth Fund's transfer
agent, Pioneer Funds' investment adviser, Pioneer, Pioneer Funds' transfer
agent, PIMSS, or by broker-dealer firms. [ ], has been retained to provide proxy
solicitation services to the Funds at a cost of approximately $[ ]. Pioneer and
AmSouth Bancorporation will bear the cost of such solicitation.

Revoking Proxies

   An AmSouth Fund shareholder signing and returning a proxy has the power to

   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 AmSouth 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.

Other Business

   Your AmSouth Fund's Board of Trustees knows of no business to be presented
for consideration at the Meeting other than Proposals 1(a)-(w). 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, by the time scheduled for the Meeting, a quorum of shareholders of a Fund
is not present or if a quorum is present but sufficient votes "for" the
proposals have not been received, the persons named as proxies may propose the
Meeting with respect to one or more of the Funds to another date and time, and
the Meeting may be held as adjourned within a reasonable time after the date set
for the original Meeting for that Fund without further notice. Any such
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 all proxies in favor of the
adjournment that voted in favor of the proposal or that abstained. They will
vote against such adjournment those proxies required to be voted against the
proposal. Broker non-votes will be disregarded in the vote for adjournment. If
the adjournment requires setting a new record date or the adjournment is for
more than 120 days of the original Meeting (in which case the Board of Trustees
of your AmSouth Fund will set a new record date), your AmSouth Fund will give
notice of the adjourned meeting to its shareholders.

Telephone Voting

   In addition to soliciting proxies by mail, by fax or in person, your AmSouth
Fund may also arrange to have votes recorded by telephone by officers and
employees of your AmSouth Fund or by personnel of the adviser or transfer agent
or a third party solicitation firm. 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

                                       23


votes would not be counted at the Meeting. Your AmSouth 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.

   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.

   o  [Insert touchtone telephone voting information]

Internet Voting

   You will also have the opportunity to submit your voting instructions via the
Internet by utilizing a program provided through the tabulator. Voting via the
Internet will not affect your right to vote in person if you decide to attend
the Meeting. Do not mail the proxy card if you are voting via the Internet. To
vote via the Internet, you will need the "control number" that appears on your
proxy card. These Internet voting procedures are designed to authenticate
shareholder identities, to allow shareholders give their voting instructions,
and to confirm that shareholders instructions have been recorded properly. If
you are voting via the Internet you 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 you.

   o  Read the proxy statement and have your proxy card at hand.

   o  Go to the Web site listed on your proxy card.

   o  Enter control number found on your proxy card.

   o  Follow the simple instructions on the Web site. Please call AmSouth Funds
      at 1-800-624-5711 if you have any problems.

   o  To insure that your instructions have been recorded correctly you will
      receive a confirmation of your voting instructions immediately after your
      submission and also by e-mail if chosen.

   o  [Insert touchtone telephone voting information]

Shareholders' Proposals

   Your AmSouth Fund is not required, and does not intend, to hold meetings of
shareholders each year. Instead, meetings will be held only when and if
required. Any shareholders desiring to present a proposal for consideration at
the next meeting for shareholders must submit the proposal in writing, so that
it is received by the your AmSouth Fund to [ ] within a reasonable time before
any meeting. If the Reorganization is completed, your AmSouth Fund will not hold
another shareholder meeting.


                                       24


Appraisal Rights

   If the Reorganization of your AmSouth Fund is approved at the Meeting,
shareholders of your AmSouth Fund will not have the right to dissent and obtain
payment of the fair value of their shares because the exercise of appraisal
rights is subject to the forward pricing requirements of Rule 22c-1 under the
Investment Company Act, which supersede state law. Shareholders of your AmSouth
Funds, however, have the right to redeem their Fund shares until the closing
date of the Reorganizations.

                    OWNERSHIP OF SHARES OF THE AMSOUTH FUNDS

   To the knowledge of your AmSouth Fund, as of May 31, 2005, the following
persons owned of record or beneficially 5% or more of the outstanding shares of
each of the AmSouth Funds.

1. TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR THE ACQUIRING FUND
   SHARES AND ASSUMPTION OF THE ASSUMED LIABILITIES; LIQUIDATION AND TERMINATION
   OF THE ACQUIRED FUND.

   1.1 Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, the Acquired Fund will
transfer all of its assets as set forth in Paragraph 1.2 (the "Acquired Assets")
to the Acquiring Fund free and clear of all liens and encumbrances (other than
those arising under the Securities Act of 1933, as amended (the "Securities
Act"), liens for taxes not yet due and contractual restrictions on the transfer
of the Acquired Assets) and the Acquiring Fund agrees in exchange therefor: (i)
to issue to the Acquired Fund the number of Acquiring Fund Shares, including
fractional Acquiring Fund Shares, of each class with an aggregate NAV equal to
the NAV of the Acquired Fund attributable to the corresponding class of the
Acquired Fund's shares, as determined in the manner set forth in Paragraphs 2.1
and 2.2; and (ii) to assume the Assumed Liabilities. Such transactions shall
take place at the Closing (as defined in Paragraph 3.1 below).

   1.2 (a) The Acquired Assets shall consist of all of the Acquired Fund's
property, including, without limitation, all portfolio securities and
instruments, dividends and interest receivables, cash, goodwill, contractual
rights and choses in action of the Acquired Fund or the AmSouth Trust in respect

originals or copies of all books and records of the



Acquired Fund, and all other assets of the Acquired Fund on the Closing Date.
The Acquiring Fund shall also be entitled to receive (or, to the extent agreed
upon between the AmSouth Trust and the Acquiring Trust, be provided access to)
copies of all records that the AmSouth Trust is required to maintain under the
Investment Company Act of 1940, as amended (the "Investment Company Act"), and
the rules of the Securities and Exchange Commission (the "Commission")

   (b) The Acquired Fund has provided the Acquiring Fund with a list of all of
the Acquired Fund's securities and other assets as of the date of execution of
this Agreement, and the Acquiring Fund has provided the Acquired Fund with a
copy of the current fundamental investment policies and restrictions and fair
value procedures applicable to the Acquiring Fund. The Acquired Fund reserves
the right to sell any of such securities or other assets before the Closing Date
(except to the extent sales may be limited by representations of the Acquired
Fund contained herein and made in connection with the issuance of the tax
opinion provided for in Paragraph 8.5 hereof).

   1.3 The Acquired Fund will endeavor to discharge all of its known liabilities
and obligations that are or will become due prior to the Closing.

   1.4 On or as soon after the Closing Date as is conveniently practicable (the
"Liquidation Date"), the AmSouth Trust shall liquidate the Acquired Fund and
distribute pro rata to its shareholders of record, determined as of the close of
regular trading on the New York Stock Exchange on the Closing Date (the

Acquired Fund pursuant to Paragraph 1.1 hereof. Each Acquired Fund Shareholder
shall receive the number of Acquiring Fund Shares of the class corresponding to
the class of shares of beneficial interest of the Acquired Fund (the "Acquired
Fund Shares") held by such Acquired Fund Shareholder that have an aggregate NAV
equal to the aggregate NAV of the Acquired Fund Shares held of record by such
Acquired Fund Shareholder on the Closing Date. Such liquidation and distribution
will be accomplished by the AmSouth Trust instructing the Acquiring Trust to
transfer 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 established and maintained by the Acquiring Fund's transfer
agent in the names of the Acquired Fund Shareholders and representing the
respective pro rata number of the Acquiring Fund Shares due the Acquired Fund
Shareholders. The AmSouth Trust shall promptly provide the Acquiring Trust with
evidence of such liquidation and distribution. All issued and outstanding
Acquired Fund Shares will simultaneously be cancelled on the books of the
Acquired Fund, and the Acquired Fund will be dissolved. The Acquiring Fund shall
not issue certificates representing the Acquiring Fund Shares in connection with
such exchange.

   1.5 Ownership of Acquiring Fund Shares will be shown on the books of the
Acquiring Fund's transfer agent. Any certificates representing ownership of
Acquired Fund Shares that remain outstanding on the Closing Date shall be deemed
to be cancelled and shall no longer evidence ownership of Acquired Fund Shares.

   1.6 Any transfer taxes payable upon issuance of Acquiring Fund 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 Acquiring Fund Shares are to be
issued and transferred.

   1.7 Any reporting responsibility of the AmSouth Trust with respect to the
Acquired Fund for taxable periods ending on or before the Closing Date,
including, but not limited to, the responsibility for filing of regulatory

Commission, any state securities commissions, and any federal, state or local
tax authorities or any other relevant regulatory authority, is and shall remain

Liabilities"), said assets and liabilities to be valued in the manner set forth

Commonwealth of Massachusetts and has the power to own all of its properties and
assets and, subject to approval by the Acquired Fund's shareholders, to perform
its obligations under this Agreement. The Acquired Fund is not required to

force and effect;

delivery of this Agreement and the performance of its obligations under this
Agreement in respect of the Acquired Fund will not result in a violation of, any
provision of the AmSouth Trust's Trust Instrument or By-Laws or any material
agreement, indenture, instrument, contract, lease or other undertaking with
respect to the Acquired Fund to which the AmSouth Trust is a party or by which
the Acquired Fund or any of its assets are bound;

      (d) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or to its knowledge

assets. The Acquired Fund knows of no facts which might form the basis for the
institution of such proceedings. Neither the AmSouth Trust 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 which materially adversely affects the Acquired
Fund's business or its ability to consummate the transactions contemplated
herein or would be binding upon the Acquiring Fund as the successor to the
Acquired Fund;

      (e) The Acquired Fund has no material contracts or other commitments
(other than this Agreement or agreements for the purchase and sale of securities
entered into in the ordinary course of business and consistent with its
obligations under this Agreement) which will not be terminated at or prior to
the Closing Date and no such termination will result in liability to the
Acquired Fund (or the Acquiring Fund);

      (f) The statement of assets and liabilities of the Acquired Fund, and the
related statements of operations and changes in net assets, as of and for the
fiscal year ended July 31, 2004, have been audited by Ernst & Young LLP,
independent registered public accounting firm, and are in accordance with
generally accepted accounting principles ("GAAP") consistently applied and

material respects, the financial condition of the Acquired Fund as of such date
and the results of its operations for the period then ended. Except for the

business or in connection with the settlement of purchases and sales of
portfolio securities. For the purposes of this subparagraph (g) (but not for any
other purpose of this Agreement), a decline in NAV per Acquired Fund Share
arising out of its normal investment operations or a decline in market values of
securities in the Acquired Fund's portfolio or a decline in net assets of the

851(b)(3) of the Code without regard to the last sentence of Section 851(d) of

of any basis upon which a jurisdiction could assert such a position;

Fund is not a party to any Tax allocation, sharing, or indemnification
agreement;

item of income in, or exclude any item of deduction from, taxable income for any
taxable period (or portion thereof) ending after the Closing Date as a result of

Acquiring Trust to the AmSouth Trust (which disclosure schedule shall be
organized by the sections of this Section 4.2 and any disclosure shall only
modify the portions of this Section 4.2 expressly identified in such schedule),
the Acquiring Trust, on behalf of the Acquiring Fund, represents, warrants and
covenants to the Acquired Fund, which representations, warranties and covenants
will be true and correct on the date hereof and on the Closing Date as though
made on and as of the Closing Date, as follows:

      (a) The Acquiring Trust is a statutory trust duly organized, validly
existing and in good standing under the laws of the State of Delaware. The
Acquiring Trust has the power to own all of its properties and assets and to
perform the obligations under this Agreement. The Acquiring Fund is not required
to qualify to do business in any jurisdiction in which it is not so qualified or
where failure to qualify would subject it to any material liability or
disability. Each of the Acquiring Trust and the Acquiring Fund has all necessary
federal, state and local authorizations to own all of its properties and assets
and to carry on its business as now being conducted;

      (b) The Acquiring Trust is a registered investment company classified as a
management company of the open-end type, and its registration with the
Commission as an investment company under the Investment Company Act is in full
force and effect;

                                      -8-


      (c) The Acquiring Fund's registration statement on Form N-1A that will be
in effect on the Closing Date, and the prospectus and statement of additional
information of the Acquiring Fund included therein, will conform in all material
respects with the applicable requirements of the Securities Act and the
Investment Company Act and the rules and regulations of the Commission
thereunder, and did not as of the effective date thereof and will not as of the
Closing Date contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
misleading;

      (d) The Registration Statement, the Proxy Statement and statement of
additional information with respect to the Acquiring Fund, and any amendments or
supplements thereto in effect on or prior to the Closing Date included in the
Registration Statement (other than written information furnished by the Acquired
Fund for inclusion therein, as covered by the Acquired Fund's warranty in
Paragraph 4.1(m) hereof) will conform in all material respects to the applicable
requirements of the Securities Act and the Investment Company Act and the rules
and regulations of the Commission thereunder. Neither the Registration Statement
nor the Proxy Statement (other than written information furnished by the
Acquired Fund for inclusion therein, as covered by the Acquired Fund's warranty
in Paragraph 4.1(m) hereof) includes or will include any untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading;

      (e) The Acquiring Trust is not in violation of, and the execution and
delivery of this Agreement and performance of its obligations under this
Agreement will not result in a violation of, any provisions of the Declaration
of Trust or by-laws of the Acquiring Trust or any material agreement, indenture,
instrument, contract, lease or other undertaking with respect to the Acquiring
Fund to which the Acquiring Trust is a party or by which the Acquiring Fund or
any of its assets is bound;

      (f) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or threatened against
the Acquiring Fund or any of the Acquiring Fund's properties or assets. The
Acquiring Fund knows of no facts which might form the basis for the institution
of such proceedings. Neither the Acquiring Trust nor the Acquiring Fund is a
party to or subject to the provisions of any order, decree or judgment of any
court or governmental body which materially adversely affects the Acquiring
Fund's business or its ability to consummate the transactions contemplated
herein;

      (g) The statement of assets and liabilities of the Acquiring Fund, and the
related statements of income and changes in NAV, as of and for the fiscal year
ended [ ] have been audited by Ernst & Young LLP, independent registered public
accounting firm, and are in accordance with GAAP consistently applied and fairly
reflect, in all material respects, the financial condition of the Acquiring Fund
as of such date and the results of its operations for the period then ended, and
all known liabilities, whether actual or contingent, of the Acquiring Fund as of
the date thereof are disclosed therein;

      (h) (A) For each taxable year of its operation since its inception, the
Acquiring Fund has met, and for the current taxable year it will meet, the
requirements of Subchapter M of the Code for qualification and treatment as a
regulated investment company and will qualify as such as of the Closing Date and
will satisfy the diversification requirements of Section 851(b)(3) of the Code
without regard to the last sentence of Section 851(d) of the Code. The Acquiring
Fund has not taken any action, caused any action to be taken or caused any
action to fail to be taken which action or failure could cause the Acquiring
Fund to fail to qualify as a regulated investment company under the Code;

          (B) Within the times and in the manner prescribed by law, the
Acquiring Fund has properly filed on a timely basis all Tax Returns that it was
required to file, and all such Tax Returns were complete and accurate in all
respects. The Acquiring Fund has not been informed by any jurisdiction that the
jurisdiction believes that the Acquiring Fund was required to file any Tax
Return that was not filed; and the Acquiring Fund does not know of any basis
upon which a jurisdiction could assert such a position;

          (C) The Acquiring Fund has timely paid, in the manner prescribed by
law, all Taxes that were due and payable or that were claimed to be due;

                                      -9-


          (D) All Tax Returns filed by the Acquiring Fund constitute complete

statements, the amounts required to be reported, and accurately set forth all
items required to be included or reflected in such returns;

          (E) The Acquiring Fund has not waived or extended any applicable
statute of limitations relating to the assessment or collection of Taxes;

foreign taxing authority, and, to its knowledge, no such deficiency has been
proposed or threatened;

          (G) The Acquiring Fund has no actual or potential liability for any
Tax obligation of any taxpayer other than itself. The Acquiring Fund is not and
has never been a member of a group of corporations with which it has filed (or
been required to file) consolidated, combined or unitary Tax Returns. The
Acquiring Fund is not a party to any Tax allocation, sharing, or indemnification
agreement;

          (H) The Acquiring Trust has delivered to AmSouth Trust or made
available to AmSouth Trust complete and accurate copies of all Tax Returns of
the Acquiring Fund, together with all related examination reports and statements

revenue agent reports, information document requests, notices of proposed
deficiencies, deficiency notices, protests, petitions, closing agreements,
settlement agreements, pending ruling requests and any similar documents
submitted by, received by or agreed to by or on behalf of the Acquiring Fund.

taken therein that could give rise to a substantial understatement of federal
income Tax within the meaning of Section 6662 of the Code;

          (I) The Acquiring Fund has not undergone, has not agreed to undergo,
and is not required to undergo (nor will it be required as a result of the

of accounting resulting in an adjustment to its taxable income pursuant to
Section 481 of the Code. The Acquiring Fund will not be required to include any
item of income in, or exclude any item of deduction from, taxable income for any
taxable period (or portion thereof) ending after the Closing Date as a result of
any (i) change in method of accounting for a taxable period ending on or prior
to the Closing Date under Section 481(c) of the Code (or any corresponding or
similar provision of state, local or foreign income Tax law); (ii) "closing
agreement" as described in Section 7121 of the Code (or any corresponding or
similar provision of state, local or foreign income Tax law) executed on or
prior to the Closing Date; (iii) installment sale or open transaction
disposition made on or prior to the Closing Date; or (iv) prepaid amount
received on or prior to the Closing Date;

is not aware of any agreement, plan or other circumstance, that is inconsistent
with the representations set forth in Annex A;

          (K) The Acquiring Fund has not incurred (or been allocated) an

          (L) The Acquiring Fund is not a party to a gain recognition agreement
under Section 367 of the Code;

          (M) The Acquiring Fund's Tax attributes are not limited under the Code
(including but not limited to any capital loss carry forward limitations under
Sections 382 or 383 of the Code and the Treasury Regulations thereunder) or
comparable provisions of state law, except as set forth on Schedule 4.2;

      (i) The authorized capital of the Acquiring Fund consists of an unlimited
number of shares of beneficial interest, no par value per share. As of the
Closing Date, the Acquiring Fund will be authorized to issue

                                      -10-


an unlimited number of shares of beneficial interest, no par value per share.
The Acquiring Fund Shares to be issued and delivered to the Acquired Fund for
the account of the Acquired Fund Shareholders pursuant to the terms of this
Agreement will have been duly authorized on the Closing Date and, when so issued
and delivered, will be duly and validly issued, fully paid and non-assessable.
The Acquiring Fund does not have outstanding any options, warrants or other
rights to subscribe for or purchase any Acquiring Fund shares, nor is there
outstanding any security convertible into any Acquiring Fund shares;

      (j) The Acquiring Trust has the trust power and authority to enter into
and perform its obligations under this Agreement. The execution, delivery and
performance of this Agreement have been duly authorized by all necessary action
on the part of the Acquiring Trust's Board of Trustees, and, assuming due
authorization, execution and delivery by the Acquired Fund, this Agreement will
constitute a valid and binding obligation of the Acquiring Fund, enforceable in
accordance with its terms, subject as to enforcement, to bankruptcy, insolvency,
reorganization, moratorium and other laws relating to or affecting creditors'
rights and to general equity principles;

      (k) The information to be furnished in writing by the Acquiring Fund or
the Acquiring Fund Adviser for use in applications for orders, registration

connection with the transactions contemplated hereby shall be accurate and
complete in all material respects and shall comply in all material respects with

requirements of any form for which its use is intended, and shall not contain
any untrue statement of a material fact or omit to state a material fact
necessary to make the information provided not misleading;

      (l) No consent, approval, authorization or order of or filing with any
court or governmental authority is required for the execution of this Agreement
or the consummation of the transactions contemplated by the Agreement by the
Acquiring Fund, except for the registration of the Acquiring Fund Shares under
the Securities Act and the Investment Company Act;

      (m) Neither the Acquiring Fund nor, to the knowledge of the Acquiring
Fund, any "affiliated person" of the Acquiring Fund has been convicted of any
felony or misdemeanor, described in Section 9(a)(1) of the Investment Company
Act, nor, to the knowledge of the Acquiring Fund, has any affiliated person of
the Acquiring Fund been the subject, or presently is the subject, of any
proceeding or investigation with respect to any disqualification that would be a
basis for denial, suspension or revocation of registration as an investment
adviser under Section 203(e) of the Investment Advisers Act or Rule 206(4)-4(b)
thereunder or of a broker-dealer under Section 15 of the Exchange Act, or for
disqualification as an investment adviser, employee, officer or director of an
investment company under Section 9 of the Investment Company Act; and

disclosed in the Acquiring Fund's prospectus, its statement of additional
information as in effect on the date of this Agreement, or its semi-annual
report for the period ended January 31, 2005, there has not been any material

except for normal contractual obligations incurred in the ordinary course of
business or in connection with the settlement of purchases and sales of
portfolio securities. For the purposes of this subparagraph (n) (but not for any
other purpose of this Agreement), a decline in NAV per Acquiring Fund Share
arising out of its normal investment operations or a decline in market values of
securities in the Acquiring Fund's portfolio or a decline in net assets of the
Acquiring Fund as a result of redemptions shall not constitute a material
adverse change;

      (o) The tax representation certificate to be delivered by the Acquiring
Trust on behalf of the Acquiring Fund to the AmSouth Trust and Wilmer Cutler
Pickering Hale and Dorr LLP at Closing pursuant to Section 6.3 (the "Acquiring

2. VALUATION

   2.1 The NAV of the Acquiring Fund Shares and the NAV of the Acquired Fund
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 NAV of each class
of Acquiring Fund Shares shall be equal to the NAV of the corresponding class of
the Acquired Fund Shares as of the Valuation Time. The NAV of the Acquired Fund
and of each Class A, B and I share thereof shall be computed by ASO Services
Company, Inc. (the "Acquired Fund Administrator") by calculating the value of
the Acquired Assets and by subtracting therefrom the amount of the liabilities
of the Acquired Fund on the Closing Date included on the Statement of Assets and
Liabilities of the Acquired Fund delivered pursuant to

                                       2


Paragraph 5.7 (the "Statement of Assets and Liabilities"), said assets and
liabilities to be valued in the manner set forth in the Acquiring Fund's then
current prospectus and statement of additional information. Pioneer Investment
Management, Inc. (the "Acquiring Fund Adviser") shall confirm to the Acquiring
Fund the NAV of the Acquired Fund.

   2.2 The number of Acquiring Fund Shares to be issued (including fractional
shares, if any) in exchange for the Acquired Assets and the assumption of the
Assumed Liabilities shall be determined by Acquiring Fund Adviser by dividing
the NAV of the Acquired Fund, as determined in accordance with Paragraph 2.1, by
the NAV of each Acquiring Fund Share, as determined in accordance with Paragraph
2.1.

   2.3 The Acquired Fund shall cause the Acquired Fund Administrator to deliver
a copy of its valuation report to the Acquiring Fund at Closing. All
computations of value shall be made by the Acquired Fund Administrator in
accordance with its regular practice as pricing agent for the Acquired Fund.

3. CLOSING AND CLOSING DATE

   3.1 The Closing Date shall be [ ], 2005, or such later date as the parties
may agree to in writing. All acts necessary to consummation the Reorganization
(the "Closing") shall be deemed to take place simultaneously as of 5:00 p.m.
(Eastern time) on the Closing Date unless otherwise provided. The Closing shall
be held at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State
Street, Boston, Massachusetts, or at such other place as the parties may agree.

   3.2 Portfolio securities that are held other than in book-entry form in the
name of AmSouth Bank (the "Acquired Fund Custodian") as record holder for the
Acquired Fund shall be presented by the Acquired Fund to Brown Brothers Harriman
& Co. (the "Acquiring Fund Custodian") for examination no later than three
business days preceding the Closing Date. Such portfolio securities shall be
delivered by the Acquired Fund to the Acquiring Fund 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 Acquired Fund Custodian in
book-entry form on behalf of the Acquired Fund shall be delivered by the
Acquired Fund Custodian through the Depository Trust Company to the Acquiring
Fund Custodian and by the Acquiring Fund Custodian recording the beneficial
ownership thereof by the Acquiring Fund on the Acquiring Fund Custodian's
records. Any cash shall be delivered by the Acquired Fund Custodian transmitting
immediately available funds by wire transfer to the Acquiring Fund Custodian the
cash balances maintained by the Acquired Fund Custodian and the Acquiring Fund
Custodian crediting such amount to the account of the Acquiring Fund.

   3.3 The Acquiring Fund Custodian shall deliver within one business day after
the Closing a certificate of an authorized officer stating that: (a) the
Acquired Assets have been delivered in proper form to the Acquiring Fund on the
Closing Date, and (b) all necessary transfer taxes including all applicable
federal and state stock transfer stamps, if any, have been paid, or provision
for payment has been made in conjunction with the delivery of portfolio
securities as part of the Acquired Assets.

   3.4 If on the Closing Date (a) the New York Stock Exchange is closed to
trading or trading thereon shall be restricted or (b) trading or the reporting
of trading on such exchange or elsewhere is disrupted so that accurate appraisal
of the NAV of the Acquired Fund pursuant to Paragraph 2.1 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.

   3.5 The Acquired Fund shall deliver at the Closing a list of the names,

Shareholders and the number and percentage ownership of outstanding Acquired
Fund Shares owned by each Acquired Fund Shareholder as of the Valuation Time,

Shareholders, (b) provided by the Acquired Fund Custodian, or (c) derived from

service providers. The Acquiring Fund shall issue and deliver to the Acquired
Fund a confirmation evidencing the Acquiring Fund Shares to be credited on 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. REPRESENTATIONS AND WARRANTIES

   4.1 Except as set forth on a disclosure schedule previously provided by the
AmSouth Trust to the Acquiring Trust (which disclosure schedule shall be
organized by the sections of this Section 4.1 and any disclosure shall only
modify the portions of this Section 4.1 expressly identified in such schedule),
the AmSouth Trust, on behalf of the Acquired Fund, represents, warrants and
covenants to the Acquiring Fund, which representations, warranties and covenants
will be true and correct on the date hereof and on the Closing Date as though
made on and as of the Closing Date, as follows:

       (a) The Acquired Fund is a series of the AmSouth Trust. The AmSouth Trust
is a business trust validly existing and in good standing under the laws of the
Commonwealth of Massachusetts and has the power to own all of its properties and
assets and, subject to approval by the Acquired Fund's shareholders, to perform
its obligations under this Agreement. The Acquired Fund is not required to
qualify to do business in any jurisdiction in which it is not so qualified or
where failure to qualify would subject it to any material liability or
disability. Each of the AmSouth Trust and the Acquired Fund has all necessary
federal, state and local authorizations to own all of its properties and assets
and to carry on its business as now being conducted;

       (b) The AmSouth Trust is a registered investment company classified as a
management company of the open-end type, and its registration with the
Commission as an investment company under the Investment Company Act is in full
force and effect;

       (c) The AmSouth Trust is not in violation of, and the execution and
delivery of this Agreement and the performance of its obligations under this
Agreement in respect of the Acquired Fund will not result in a violation of, any
provision of the AmSouth Trust's Trust Instrument or By-Laws or any material
agreement, indenture, instrument, contract, lease or other undertaking with
respect to the Acquired Fund to which the AmSouth Trust is a party or by which
the Acquired Fund or any of its assets are bound;

       (d) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or to its knowledge
threatened against the Acquired Fund or any of the Acquired Fund's properties or
assets. The Acquired Fund knows of no facts which might form the basis for the
institution of such proceedings. Neither the AmSouth Trust 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 which materially adversely affects the Acquired
Fund's business or its ability to consummate the transactions contemplated
herein or would be binding upon the Acquiring Fund as the successor to the
Acquired Fund;

       (e) The Acquired Fund has no material contracts or other commitments
(other than this Agreement or agreements for the purchase and sale of securities
entered into in the ordinary course of business and consistent with its
obligations under this Agreement) which will not be terminated at or prior to
the Closing Date and no such termination will result in liability to the
Acquired Fund (or the Acquiring Fund);

       (f) The statement of assets and liabilities of the Acquired Fund, and the
related statements of operations and changes in net assets, as of and for the
fiscal year ended July 31, 2004 have been audited by Ernst & Young LLP,
independent registered public accounting firm, and are in accordance with
generally accepted accounting principles ("GAAP") consistently applied and
fairly reflect, in all material respects, the financial condition of the
Acquired Fund as of such date and the results of its operations for the period
then ended, and all known liabilities, whether actual or contingent, of the
Acquired Fund as of the date thereof are disclosed therein. The Statement of
Assets and Liabilities will be in accordance with GAAP consistently applied and
will fairly reflect, in all material respects, the financial condition of the
Acquired Fund as of such date and the results of its operations for the period
then ended. Except for the Assumed Liabilities, the Acquired Fund will not have
any known or contingent liabilities on the Closing Date. No significant
deficiency, material weakness, fraud, significant change or

                                       4


other factor that could significantly affect the internal controls of the
Acquired Fund has been disclosed or is required to be disclosed in the Acquired
Fund's reports on Form N-CSR to enable the chief executive officer and chief
financial officer or other officers of the Acquired Fund to make the
certifications required by the Sarbanes-Oxley Act, and no deficiency, weakness,
fraud, change, event or other factor exists that will be required to be
disclosed in the Acquiring Fund's Form N-CSR after the Closing Date;

       (g) Since the most recent fiscal year end, except as specifically
disclosed in the Acquired Fund's prospectus, its statement of additional
information as in effect on the date of this Agreement, or its semi-annual
report for the period ended January 31, 2005, there has not been any material
adverse change in the Acquired Fund's financial condition, assets, liabilities,
business or prospects, or any incurrence by the Acquired Fund of indebtedness,
except for normal contractual obligations incurred in the ordinary course of
business or in connection with the settlement of purchases and sales of
portfolio securities. For the purposes of this subparagraph (g) (but not for any
other purpose of this Agreement), a decline in NAV per Acquired Fund Share
arising out of its normal investment operations or a decline in market values of
securities in the Acquired Fund's portfolio or a decline in net assets of the
Acquired Fund as a result of redemptions shall not constitute a material adverse
change;

       (h) (A) For each taxable year of its operation since its inception, the
Acquired Fund has met, and for the current taxable year it will meet, the
requirements of Subchapter M of the Code for qualification and treatment as a
regulated investment company and will qualify as such as of the Closing Date and
will satisfy the diversification requirements of Section 851(b)(3) of the Code
without regard to the last sentence of Section 851(d) of the Code. The Acquired
Fund has not taken any action, caused any action to be taken or caused any
action to fail to be taken which action or failure could cause the Acquired Fund
to fail to qualify as a regulated investment company under the Code;

           (B) Within the times and in the manner prescribed by law, the
Acquired Fund has properly filed on a timely basis all Tax Returns (as defined

to file any Tax Return that was not filed; and the Acquired Fund does not know
of any basis upon which a jurisdiction could assert such a position;

           (C) The Acquired Fund has timely paid, in the manner prescribed by
law, all Taxes (as defined below), which were due and payable or which were
claimed to be due;

Acquired Fund or, in the case of information returns and payee statements, the

the Tax Returns of the Acquired Fund are currently in progress or threatened,

proposed or threatened;

has never been a member of a group of corporations with which it has filed (or
been required to file) consolidated, combined or unitary Tax Returns. The
Acquired Fund is not a party to any Tax allocation, sharing, or indemnification
agreement;

Closing Date do not exceed the accruals and reserves for Taxes (excluding

differences between book and Tax income) set forth on the Statement of Assets
and Liabilities, rather than in any notes thereto (the "Tax Reserves"). All
Taxes that the Acquired Fund is or was

                                       5


required by law to withhold or collect have been duly withheld or collected and,

Fund. The Acquired Fund has disclosed on its federal income Tax Returns all
positions taken therein that could give rise to a substantial understatement of
federal income Tax within the meaning of Section 6662 of the Code;

           (J) The Acquired Fund has not undergone, has not agreed to undergo,
and is not required to undergo (nor will it be required as a result of the
transactions contemplated in this Agreement to undergo) a change in its method
of accounting resulting in an adjustment to its taxable income pursuant to
Section 481 of the Code. The Acquired Fund will not be required to include any
item of income in, or exclude any item of deduction from, taxable income for any
taxable period (or portion thereof) ending after the Closing Date as a result of
any (i) change in method of accounting for a taxable period ending on or prior
to the Closing Date under Section 481(c) of the Code (or any corresponding or
similar provision of state, local or foreign income Tax law); (ii) "closing
agreement" as described in Section 7121 of the Code (or any corresponding or
similar provision of state, local or foreign income Tax law) executed on or
prior to the Closing Date; (iii) installment sale or open transaction

characterized as a partnership for income tax purposes;

           (Q) The Acquired Fund's Tax attributes are not limited under the Code
(including but not limited to any capital loss carry forward limitations under
Sections 382 or 383 of the Code and the Treasury Regulations thereunder) or
comparable provisions of state law; and

           (R) For purposes of this Agreement, "Taxes" or "Tax" shall mean all

defined herein shall have the meanings ascribed to them in the Agreement.

   1. Acquiring Fund is a series of Acquiring Trust, a statutory trust organized
under the laws of the State of Delaware, and Acquiring Fund will be treated
after the Closing as a separate corporation for federal tax purposes. Acquiring
Fund was newly organized solely for the purpose of effecting the transaction and
continuing thereafter to operate as a regulated investment company. Prior to the
transaction, Acquiring Fund did not and will not engage in any business
activities. There shall be no shares of Acquiring Fund issued and outstanding
prior to the Closing Date other than those issued to Pioneer Investment
Management, Inc. or one of its affiliates in connection with the creation of
Acquiring Fund, which shares shall be redeemed, for an amount equal to the price
paid therefor, at or before the Closing.

   2. Neither Acquiring Fund nor any person "related" to Acquiring Fund (as
defined in Treasury Regulation Section 1.368-1(e)(3)), nor any partnership of
which Acquiring Fund or any such related person is a partner, has any plan or
intention to redeem or otherwise acquire any of the Acquiring Fund Shares
received by shareholders of Acquired Fund in the transaction except in the
ordinary course of Acquiring Fund's business in connection with its legal
obligation under Section 22(e) of the Investment Company Act of 1940, as amended
(the "1940 Act"), as a series of a registered open-end investment company to
redeem its own shares.

   3. After the transaction, Acquiring Fund will continue the historic business
(as defined in Treasury Regulation Section 1.368-1(d)(2)) of Acquired Fund or
will use a significant portion of the historic business assets (as defined in
Treasury Regulation Section 1.368-1(d)(3)) of Acquired Fund in a business.

   4. Acquiring Fund has no plan or intention to sell or otherwise dispose of
any assets of Acquired Fund acquired in the transaction, except for dispositions
made in the ordinary course of its business or to maintain its qualification as
a regulated investment company under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code").

   5. Any expenses of Acquired Fund incurred in connection with the transaction
which are paid or assumed by Acquiring Fund will be expenses of Acquired Fund
solely and directly related to the transaction in accordance with Rev. Rul. 73
54, 1973 1 C.B. 187. Acquiring Fund will not pay or assume the expenses, if any,
incurred by any Acquired Fund Shareholders in connection with the transaction.

   6. There is no, and never has been any, indebtedness between Acquiring Fund
and Acquired Fund.

                                      A-1

similar case within the meaning of Section 368(a)(3)(A) of the Code.

   10. Acquiring Fund does not now own and has never owned, directly or
indirectly, any shares of Acquired Fund.

   11. As of the date of the transaction, the fair market value of the Acquiring
Fund Shares issued to Acquired Fund will be approximately equal to the fair
market value of the Acquired Assets minus the Assumed Liabilities. Acquiring
Fund will not furnish any consideration in connection with the acquisition of
the Acquired Assets other than the assumption of the Assumed Liabilities and the
issuance of such Acquiring Fund Shares.

   12. Immediately following the transaction, the Acquired Fund Shareholders
will own all of the outstanding Acquiring Fund Shares and will own such shares
solely by reason of their ownership of the Acquired Fund Shares immediately
prior to the transaction. Acquiring Fund has no plan or intention to issue as
part of the transaction any shares of Acquiring Fund other than the Acquiring
Fund Shares issued in exchange for the Acquired Assets.

   13. The transaction is being undertaken for valid and substantial business
purposes, including facilitating Acquired Fund's becoming a member of the
Pioneer family of mutual funds, which, in the long term, is intended to result
in lower expenses and increased assets.

   14. No Acquired Fund shareholder is acting as agent for Acquiring Fund in
connection with the transaction or approval thereof. Acquiring Fund will not
reimburse any Acquired Fund shareholder for Acquired Fund Shares such
shareholder may have purchased or for other obligations such shareholder may
have incurred.

   15. Acquiring Fund has no outstanding warrants, options, convertible
securities or any other type of right pursuant to which any person could acquire

                                  AMSOUTH FUNDS
                          ON BEHALF OF AMSOUTH [ ] FUND

   This certificate is being delivered in connection with the transactions to be
effected pursuant to the Agreement and Plan of Reorganization made as of [ ],
2005 between Pioneer [ ] Fund, a Delaware statutory trust, on behalf of its
series Pioneer [ ] Fund ("Acquiring Fund"), and AmSouth Funds, a Massachusetts
business trust ("AmSouth Trust"), on behalf of its series AmSouth [ ] Fund
("Acquired Fund") (the "Agreement"). Pursuant to the Agreement, Acquiring Fund
will acquire all of the assets of Acquired Fund in exchange solely for (i) the
assumption by Acquiring Fund of the Assumed Liabilities of Acquired Fund and
(ii) the issuance of shares of beneficial interest of Acquiring Fund (the
"Acquiring Fund Shares") to Acquired Fund, followed by the distribution by
Acquired Fund, in liquidation of Acquired Fund, of the Acquiring Fund Shares to
the shareholders of Acquired Fund and the termination of Acquired Fund (the
foregoing together constituting the "transaction").

   The undersigned officer of AmSouth Trust, after consulting with its counsel,
auditors and tax advisers regarding the meaning of and factual support for the
following representations, on behalf of Acquired Fund, hereby certifies and
represents that the following statements are true, complete and correct and will
be true, complete and correct on the date of the transaction and thereafter as
relevant. Unless otherwise indicated, all capitalized terms used but not defined
herein shall have the meanings ascribed to them in the Agreement.

   1. Acquired Fund is a series of AmSouth Funds, a business trust organized
under the laws of the Commonwealth of Massachusetts, and Acquired Fund is, and
has been at all times, treated as a separate corporation for federal tax
purposes.

   2. As of the date of the transaction, the fair market value of the Acquiring
Fund Shares received by each shareholder that holds shares of Acquired Fund (the
"Acquired Fund Shares") will be approximately equal to the fair market value of
the Acquired Fund Shares with respect to which such Acquiring Fund Shares are
received, and the aggregate consideration received by Acquired Fund shareholders
in exchange for their Acquired Fund Shares will be approximately equal to the
fair market value of all of the outstanding Acquired Fund Shares immediately
prior to the transaction. No property other than Acquiring Fund Shares will be
distributed to shareholders of Acquired Fund in exchange for their Acquired Fund
Shares, nor will any such shareholder receive cash or other property as part of
the transaction.

   3. Neither Acquired Fund nor any person "related" to Acquired Fund (as
defined in Treasury Regulation Section 1.368-1(e)(3)), nor any partnership in
which Acquired Fund or any such related person is a partner, has redeemed,
acquired or otherwise made any distributions with respect to any shares of
Acquired Fund as part of the transaction, or otherwise pursuant to a plan of
which the transaction is a part, other than redemptions and distributions made
in the ordinary course of Acquired Fund's business as a series of an open-end
investment company. To the best knowledge of management of Acquired Fund, there
is no plan or intention on the part of the shareholders of Acquired Fund to
engage in any transaction with Acquired Fund, Acquiring Fund, or any person
treated as related to Acquired Fund or Acquiring Fund under Treasury Regulation
Section 1.368-1(e)(3) or any partnership in which Acquired Fund, Acquiring Fund,
or any person treated as related to Acquired Fund or Acquiring Fund under
Treasury Regulation Section 1.368-1(e)(3) is a partner involving the sale,
redemption or exchange of any of the Acquired Fund Shares or any of the
Acquiring Fund Shares to be received in the transaction, as the case may be,
other than in the ordinary course of Acquired Fund's business as a series of an
open-end investment company.

   4. In the transaction, Acquired Fund will transfer its assets to Acquiring
Fund, which will assume the Assumed Liabilities, such that immediately following
the transfer, Acquiring Fund will possess all of the same assets and liabilities
as were possessed by Acquired Fund immediately prior to the transaction, except
for assets used to pay expenses incurred in connection with the transaction and
assets distributed to shareholders in redemption of their shares immediately
preceding, or in contemplation of, the transaction (other than redemptions and
distributions

                                      B-1


made in the ordinary course of Acquired Fund's business as an open-end
investment company) which assets constitute less than 1% of the net assets of
Acquired Fund.

   5. As of the date of the transaction, the fair market value of the Acquiring
Fund Shares issued to Acquired Fund will be approximately equal to the fair
market value of the Acquired Assets minus the Assumed Liabilities. Acquired Fund
will not receive any consideration from Acquiring Fund in connection with the
acquisition of the Acquired Assets other than the assumption of the Assumed
Liabilities and the issuance of such Acquiring Fund Shares.

   6. The Assumed Liabilities assumed by Acquiring Fund plus the Assumed
Liabilities, if any, to which the transferred assets are subject were incurred
by Acquired Fund in the ordinary course of its business. Acquired Fund is not
aware of any liabilities of any kind other than the Assumed Liabilities.

   7. As of the Closing Date, the adjusted basis and the fair market value of
the Acquired Assets will equal or exceed the Assumed Liabilities assumed for
purposes of Section 357(d) of the Code.

   8. Acquired Fund currently conducts its historic business within the meaning
of Treasury Regulation Section 1.368-1(d)(2), which provides that, in general, a
corporation's historic business is the business it has conducted most recently,
but does not include a business that the corporation enters into as part of a
plan of reorganization. The Acquired Fund assets transferred to Acquiring Fund
will be Acquired Fund's historic business assets within the meaning of Treasury
Regulation Section 1.368-1(d), which provides that a corporation's historic
business assets are the assets used in its historic business.

   9. Acquired Fund will distribute to its shareholders the Acquiring Fund
Shares it receives pursuant to the transaction, and its other properties, if
any, and will be liquidated promptly thereafter.

   10. The expenses of Acquired Fund incurred by it in connection with the
transaction, if any, will be only such expenses that are solely and directly
related to the transaction in accordance with Rev. Rul. 73-54, 1973-1 C.B. 187.
Acquired Fund will not pay any expenses incurred by its shareholders in
connection with the transaction.

   11. There is no, and never has been any, indebtedness between Acquiring Fund
and Acquired Fund.

   12. Acquired Fund has properly elected to be a regulated investment company
under Subchapter M of the Code, has qualified for the special tax treatment
afforded regulated investment companies under Subchapter M of the Code for each
taxable year since inception, and qualifies for such treatment as of the time of
the Closing.

   13. Acquired Fund meets the requirements of an "investment company" in
Section 368(a)(2)(F) of the Code.

   14. Acquired Fund is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

   15. Acquired Fund does not pay compensation to any shareholder-employee.

   16. Immediately following the transaction, the Acquired Fund Shareholders
will own all of the outstanding Acquiring Fund Shares and will own such shares
solely by reason of their ownership of the Acquired Fund Shares immediately
prior to the transaction.

   17. Acquired Fund shareholders will not have dissenters' or appraisal rights
in the transaction.

   18. The transaction is being undertaken for valid and substantial business
purposes, including facilitating Acquired Fund's becoming a member of the
Pioneer family of mutual funds, which, in the long term, is intended to result
in lower expenses and increased assets.

                                      B-2


   19. Acquired Fund has no outstanding warrants, options, convertible
securities or any other type of right pursuant to which any person could acquire
stock in Acquired Fund.

            Exhibit B -- Additional Information Pertaining to Pioneer

PORTFOLIO TRANSACTION POLICIES

   All orders for the purchase or sale of portfolio securities are placed on
behalf of each fund by Pioneer pursuant to authority contained in the fund's
management contract. Pioneer seeks to obtain the best execution on portfolio
trades. The price of securities and any commission rate paid are always factors,
but frequently not the only factors, in judging best execution. In selecting
brokers or dealers, Pioneer considers various relevant factors, including, but
not limited to, the size and type of the transaction; the nature and character
of the markets for the security to be purchased or sold; the execution
efficiency, settlement capability and financial condition of the dealer; the
dealer's execution services rendered on a continuing basis; and the
reasonableness of any dealer spreads. Transactions in non-U.S. equity securities
are executed by broker-dealers in non-U.S. countries in which commission rates
may not be negotiable (as such rates are in the U.S.).

   Pioneer may select broker-dealers that provide brokerage and/or research
services to a fund and/or other investment companies or other accounts managed
by Pioneer. In addition, consistent with Section 28(e) of the Securities
Exchange Act of 1934 as amended, if Pioneer determines in good faith that the
amount of commissions charged by a broker-dealer is reasonable in relation to
the value of the brokerage and research services provided by such broker, the
fund may pay commissions to such broker-dealer in an amount greater than the
amount another firm may charge. Such services may include advice concerning the
value of securities; the advisability of investing in, purchasing or selling
securities; the availability of securities or the purchasers or sellers of
securities; providing stock quotation services, credit rating service
information and comparative fund statistics; furnishing analyses, electronic
information services, manuals and reports concerning issuers, industries,
securities, economic factors and trends, portfolio strategy, and performance of
accounts and particular investment decisions; and effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement). Pioneer maintains a listing of broker-dealers who provide such
services on a regular basis. However, because many transactions on behalf of a
fund and other investment companies or accounts managed by Pioneer are placed
with broker-dealers (including broker-dealers on the listing) without regard to
the furnishing of such services, it is not possible to estimate the proportion
of such transactions directed to such dealers solely because such services were
provided. Pioneer believes that no exact dollar value can be calculated for such
services.

   The research received from broker-dealers may be useful to Pioneer in
rendering investment management services to any of the funds as well as other
investment companies or other accounts managed by Pioneer, although not all such
research may be useful to any of the funds. Conversely, such information
provided by brokers or dealers who have executed transaction orders on behalf of
such other accounts may be useful to Pioneer in carrying out its obligations to
any of the funds. The receipt of such research has not reduced Pioneer's normal
independent research activities; however, it enables Pioneer to avoid the
additional expenses which might otherwise be incurred if it were to attempt to
develop comparable information through its own staff.

   None of the funds used any brokers affiliated with Pioneer during its most
recently completed fiscal year in connection with its portfolio transactions.

Portfolio Management Discussion  11/30/04

In the following interview, David Klaskin, Pioneer Oak Ridge Large Cap Growth
Fund's Lead Portfolio Manager, discusses the factors that influenced performance
for the twelve months ended November 30, 2004.

Q: How did the U.S. stock market perform during the Fund's fiscal year?

A: Stocks performed very well during the past year, as continued global growth,
favorable earnings results and improving corporate balance sheets combined to
form a solid foundation for the market. While stocks provided a reasonable
return, their upward path was very choppy due to weakness in the second and
third quarters. During this time, the market was pressured by a litany of
concerns that included geopolitical tensions, soaring oil prices and rising U.S.
interest rates. Investors, therefore, began to rotate into higher-quality stocks
with solid fundamentals, and away from the riskier stocks that had been top
performers during 2003 and the first quarter of this year. This shift was a
positive for the Fund, given our focus on higher quality, fundamentally sound
companies.

                                      C-3


Q: How did Pioneer Oak Ridge Large Cap Growth Fund perform?

A: Class A shares of the Fund produced a total return of 11.90% at net asset
value for the twelve-month period ended November 30, 2004, outpacing the 5.83%
return of the Russell 1000 Growth Index. The Fund's Class A shares finished in
the top 7% of the 647 funds in the Lipper Large Cap Growth Funds peer group for
the one-year period. The performance data quoted represents past performance,
which is no guarantee of future results. Investment return and principal value
will fluctuate, and shares, when redeemed, may be worth more or less than their
original cost. We are pleased that the Fund has performed well both on an
absolute basis and relative to its benchmark and peer group. While past
performance is no guarantee of future results, of course, we believe the Fund's
strong showing is the result of our disciplined investment style. Like all
growth managers, we look for companies with accelerating earnings. However, we
also require that two other important factors be in place. First, our research
must indicate to us that an issue's earnings growth is sustainable. And second,
the stocks we purchase must be reasonably valued in our view, since even
fast-growing stocks can be very risky if they are purchased at too rich of a
price. We believe this approach is the best way to find companies that are
poised to perform well over a three- to five-year time horizon.

Q: How is the Fund positioned in the two largest industry sectors in the Russell
   1000 Growth Index: technology and health care?

A: We added significant relative value through our approach to the technology
sector, which underperformed the general market due to the prospect of slowing
sales growth in 2005. In this environment, our relatively conservative
positioning - i.e., our focus on reasonably valued, blue chip companies within
the sector - paid off. In addition, performance was helped by the fact that
technology is the Fund's largest sector underweight (a weighting below that of
the benchmark). Two of the Fund's top performers in technology were Qualcomm,
whose business model of earning royalties for its wireless communications
technology has enabled the stock to perform well amid broader tech weakness; and
Dell Computer, which continues to gain market share from its competitors. The
portfolio also was helped by being underweight in the more cyclical areas within
technology, such as semiconductors. In particular, our decision to avoid Intel -
which underperformed by a wide margin during the period - proved to be a
distinct positive for performance. Turning to health care, we added significant
value through our decision to avoid the large-cap pharmaceuticals sector.
Although these stocks are now as inexpensive as they were following President
Clinton's attempt at sweeping health care reform in 1993, we believe there are
not enough new drugs in the pipeline to make up for the lost revenues from drugs
that are coming off patent protection. We looked instead for opportunities among
service providers and equipment companies, such as Zimmer Holdings - a leading
manufacturer of orthopedic products. Zimmer declined in the third quarter on
weaker than expected earnings, prompting us to trim the position, but the stock
was a strong contributor for the full year. On the negative side, the generic
drug maker Teva Pharmaceuticals was one of the Fund's leading detractors. We
continue to hold the stock, however, as we remain confident in its longer term
prospects.

Q: What other elements of the Fund's positioning affected performance?

A: Energy stocks performed very well during the period, as the rising prices of
oil and gas boosted profits for companies in the sector. The Fund was helped by
both an overweight position and strong stock selection within the group. We
received strong performance from XTO Energy, which has demonstrated the ability
to manage its business effectively even during difficult times. Apache, an
exploration and production company that reported record production and 57%
earnings growth during the third quarter, also performed very well for the Fund.
In the consumer discretionary area, the online auction company eBay provided
stellar performance. eBay has emerged as a true "category killer," meaning that
there is no other company that has come close to being able to establish a
stronghold in its market space. While the company's fundamentals remain strong,
we have begun to trim the position on the basis of its valuation. Specialty
retailers such as Staples and Best Buy also contributed positively to
performance. A key detractor within the consumer discretionary group was
IAC/InteractiveCorp, which integrates a variety of online businesses. While we
believed this would allow the company to benefit from increased online activity,
the stock fell following the release of disappointing second quarter results. In
the financial sector, we have gradually reduced the presence of companies that
are sensitive to interest rate movements - such as traditional banks - given
that the Federal Reserve is likely to continue raising rates. At the same time,
we have maintained the Fund's positions in stocks with more diversified business
lines that have the potential to benefit from continued strength in the economy,
such as Sallie Mae and American Express. A top performer among financials was
Popular, which holds a strong market position within Latin America and the
fast-growing Hispanic population in the United States.

Q: What is your outlook for the stock market?

                                      C-4


A: There are a number of factors that continue to work in the market's favor,
including steady worldwide growth, the improvement in corporate balance sheets
and companies' growing focus on dividends and share buybacks. However, the risks
to market performance, which include rising interest rates and the potential for
geopolitical disruptions, remain firmly in place. As a result, we think the
post-bubble rally in lower-quality, higher-risk companies has likely run its
course, and this should translate into a continued investor preference for
higher quality companies with strong fundamentals. In this environment, we
believe we can continue to add value through our disciplined, selective approach
to investing. The Fund invests in a limited number of securities and, as a
result, the Fund's performance may be more volatile than the performance of
funds holding more securities.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are

These statements should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

Portfolio Management Discussion   12/31/04

In the following discussion, John Carey, portfolio manager of Pioneer Fund,
reviews the past year and gives an overview of Pioneer Fund's performance over
that period.

Q: How did the Fund perform versus its benchmark and peer group? To what do you
   attribute the performance?

A: Pioneer Fund achieved respectable returns in 2004. Class A shares rose
11.64%, at net asset value for the calendar year. Most of the gain came in the
fourth quarter, which saw the Class A shares rise 9.69%. By comparison, the
Standard & Poor's (S&P) 500 Index, an unmanaged index of the general stock
market, increased by 11.04% for the year and 9.23% in the fourth quarter, and
the average fund in the Lipper Large-Cap Core category appreciated by 7.79% for
the year and 8.86% in the fourth quarter. For the second half of 2004, the
corresponding numbers were: +9.41% at net asset value for Pioneer Fund; +7.19%
for the S&P 500 Index; and +5.64% for the average fund in the Lipper Large- Cap
Core category. After a halting start to the year in the first half, the market
performed well in the second half, and Pioneer Fund more than kept pace. The
performance data quoted represents past performance, which is no guarantee of
future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.
Looking back at our June 30 shareholder letter, we read our description of a
market apparently in disarray, but with some discernible trends. Principally we
noted the disappointing performance of some of the market darlings of the
previous year, 2003, especially in technology, as investors during 2004 rotated
into more moderately priced shares with dividends and more stable earnings.
While it looked as though investors did not know what to do amidst all of their
worries about rising interest rates, the war in Iraq, the weak dollar, rising
oil prices, terrorist threats, and the upcoming Presidential election, they did
in fact have a pretty clear idea. Seeking

                                      C-8


security in dividends and modest valuations, and also in companies likely to
benefit from some of the circumstances causing their worries, investors heavily
bought and drove up the prices of energy, utility, industrial, and materials
stocks. The fourth-quarter rally broadened somewhat towards the end of the year,
but overall, 2004 was distinctly the year of the "old economy." Many of the
best-performing stocks were in industries like coal, copper, and iron-ore
mining, oil and gas, railroads, steel, hotels and lodging, building materials,
machinery, home construction, and ocean shipping. Our founder, Philip Carret,
would have been quite comfortable in the market of 2004 because without
exception all of those industries also existed, and were prospering, in the year
of his birth, 1896. For Pioneer Fund, the better-than-average performance was
derived both from our solid weightings in many of the old-economy stocks,
especially in energy, industrials, and materials, and from our good stock
selection in the four sectors that underperformed the S&P 500 average, consumer
staples, financials, health care, and information technology. Among our
best-performing stocks were Norfolk Southern and PACCAR in industrials and T.
Rowe Price in financials, but we also benefited from having only modest relative
exposure to Pfizer and Cisco Systems (which we sold during the year) and no
holdings of Coca-Cola, all stocks that did poorly. We did suffer from having
above-market weightings in two of the dismal semiconductor names, Applied
Materials and Texas Instruments, but on the whole we managed to avoid most of
the "disaster" stocks. We were particularly pleased that consumer discretionary,
the sector we had highlighted in our annual report for 2003 as the "major
culprit" in our relative underperformance versus the S&P during that year, was a
positive contributor to Fund performance in 2004. Three of our largest gains
were from stocks in that sector: McGraw-Hill, Target, and John Wiley & Sons.

Q: What changes did you make to the portfolio during the second half?

A: The list of 32 additions to and 10 deletions from the portfolio in the second
half of 2004 makes it look as though the period was a singularly busy one for
Pioneer Fund. Actually it was just a normally busy time, but due to the merger
of an acquired fund, the Safeco Core Equity Fund, into Pioneer Fund during
December, we ended up with some 20 new, transferred positions. Most of the
Safeco fund, totaling about $700 million in assets, overlapped with positions
already owned in Pioneer Fund, but we inherited the others as well. Rather than
"throwing them all out with the wash," we thought that we would take our time to
study them in the expectation that some might prove to be worthwhile longer-term
holdings for Pioneer Fund. The merger itself marked an exciting increase to the
asset base of Pioneer Fund, and also to our shareholder family. To our new,
formerly Safeco fund shareholders, a hearty welcome! The total effect of the
portfolio activity on sector weights was modest, with no sector weighting going
up or down by as much as 2%. Materials, industrials, consumer discretionary,
information technology, and telecommunications services all increased as a
percentage of the Fund portfolio, and energy, consumer staples, health care,
financials, and utilities all decreased. As examples, in materials we added: BHP
Billiton, a major Australian-based mining and minerals company; Inco, the
Canadian nickel producer; and Newmont Mining, a leading gold miner. Two new
materials names came from the Safeco fund, Praxair, supplier of industrial
gases, and Ball, a packaging company. Among industrials, Northrup Grumman and
Ingersoll-Rand were both Safeco holdings, and in the case of consumer
discretionary, five of the eight new stocks came from the Safeco fund. The two
largest additions, however, were our own purchases, Nordstrom and Gap, both of
them retailing companies showing signs of meaningful operational improvement
over the past couple of years. Information technology rose somewhat with: our
purchase of Veritas Software, which has received a merger proposal from another
portfolio company, Symantec; the receipt of shares of Freescale Semiconductor
from our holding Motorola; and the inclusion of EMC, an information storage
specialist, from the Safeco fund. Telecommunications saw one purchase by us,
Nextel Communications, and two additions attributable to the Safeco fund,
CenturyTel and Verizon. Subsequent to our purchase of Nextel, the company
entered into merger discussions with Sprint. In regard to the sectors where the
weightings decreased, the reasons in some cases had to do with weaker relative
share-price performance and in other cases with sales from the portfolio. In
energy, we realized a gain on a large position in Smith International and
replaced it with a smaller holding of Schlumberger. With consumer staples,
despite the addition of two small positions from the Safeco portfolio, Kellogg
and Kimberly Clark, the sector declined as a percent of the Fund due to
underperformance versus the market averages. In the case of health care, it was
a combination of selling in excess of purchasing and woeful stock performance
from some of the pharmaceuticals, especially Mylan Labs, which announced an
acquisition that many investors thought ill conceived. During the six months, we
realized significant percentage gains on our sales of Biomet and Wellpoint
Health Networks, while adding two names in the health-care equipment and
supplies industry, Stryker and Medtronic, and one name in biotechnology, Amgen.
Medtronic and Amgen were both from the Safeco fund. Financials saw SouthTrust
stock exchanged for shares of Wachovia in a merger and our shares of Charter One
Financial acquired for cash by the Royal Bank of Scotland. We sold our position
in St. Paul Travelers after discouragement over the company's need to set up
additional reserves following the merger creating the company. Finally, in
utilities, we sold a position in Vectren and received a smaller position in
Exelon from the Safeco fund. We have not listed every change, but rather have
mentioned the more significant ones and summarized the impact on the portfolio.

Q: What is your outlook for 2005?

                                      C-9


A: The economic outlook appears favorable over the coming year. Interest rates
are expected to continue rising, but not so fast that they should present
impediments to further economic growth.

Earnings growth will moderate somewhat, which is normal as a business cycle
lengthens, but should still be adequate to fuel additional share-price advances.
Federal tax law, with the maximum 15% tax rate on qualified dividends and
long-term capital gains, is likewise favorable to the stock market. Of course
there are concerns, including energy and other commodity prices and the high
trade and Federal budget deficits. At some point, too, investors will begin
looking ahead to the next downturn in the economy and thinking about ways to
position themselves more defensively. A lot rides on the length of the current
business cycle. That is, will this be a "normal" cycle of four years or
thereabouts, or could it become another extended cycle like the one of the
1990s, which continued for more than six years? Making the forecasting even more
difficult is the unusual circumstance that this is a wartime cycle, with some
economic activity not conforming to more predictable business patterns. We are
somewhat inclined to the view that this will be an extended cycle, due to the
excruciatingly slow start to the recovery this time around and the persisting
cautiousness of many corporate managements. There generally have to be signs of
"excesses" before an economy rolls over, and we are not speaking of the recent
$44 million apartment sale in New York City or the advertised pricing of some
luxury cars above $300,000. Rather we are speaking of excessive hiring and
capital spending, leading to unneeded productive capacity, unsellable inventory,
and superfluous workers, and none of that has popped up yet at least on our
radar screen. So we think that we have some reasonable amount of time ahead of
us for making money in the market. As always, though, we are mainly interested
in companies that have the financial and management strengths to survive and do
well regardless of the economic climate, and especially companies with the
potential, as well as a plan and the management commitment, to do better than
they have in the past. A good economy creates more opportunities for such
companies to achieve improved results.

Thank you very much for your interest and support.

Portfolio Management Discussion 10/31/04

Investors reacted to a variety of different influences during the 12-month
period ended October 31, 2004, but the dominant trend in the market was for
stock prices to move higher as the economy expanded and corporate profits grew.
During the period, mid-cap stocks tended to outperform both large-cap and
small-cap stocks, and value stocks outperformed growth stocks. In the following
discussion, Rod Wright, leader of the team that manages Pioneer Mid Cap Value
Fund, provides an update on the Fund, its investment strategies and the economic
environment during the 12-month period.

Q: How did the Fund perform?

A: The Fund did well, outperforming the average return of competitive funds
despite trailing the benchmark Russell Midcap Value Index. The Fund's Class A
shares had a total return of 17.65% for the 12 months ended October 31, 2004,
while Class B and Class C shares returned 16.64% and 16.60%, respectively, all
at net asset value. During the same period, the Russell Midcap Value Index
gained 19.74%, while the average return of the 228 funds in Lipper's Mid-Cap
Value category was 15.64%.

Q: What were the principal factors affecting Fund performance?

A: The market began the period, in the final quarter of calendar 2003, building
on the rally that had characterized much of 2003, with stock prices rising amid
expectations that the economy was entering a period of sustained economic
growth. The surge continued through early spring of 2004, when investors began
to be concerned about a host of other influences, including high stock
valuations, the instability in Iraq, political uncertainty and rapidly rising
oil prices. The combination of these concerns stalled the rally until late in
the period, when prices again advanced amid renewed optimism about the strength
of the economy. The Fund's selections in technology, energy, consumer
discretionary and telecommunications services helped support strong performance,
while investments in industrials and financial services tended to detract from
performance. The underperformance of the Fund, relative to the Russell Midcap
Value Index, was primarily due to the absence of any investments in real estate
investment trusts (REITs), part of the financial services sector. The Fund's
defensive positioning in the financial services sector also held back
performance, as market interest rates did not increase by as much as we had
anticipated and many banks and other interest rate sensitive companies continued
to perform well.

                                      C-13


Q: What were some of the individual investments that most influenced
   performance?

A: Foot Locker, a specialty retailer focusing on athletic apparel, was a major
contributor to performance, as its earnings accelerated. Transocean, the world's
largest offshore oil-drilling company, posted big gains, as world oil prices
advanced, stimulating drilling activity. Phelps Dodge, the world's second
largest copper mining company, was another major contributor, as the prices of
copper and other basic materials climbed because of surging economic growth
throughout the world. Foot Locker remained the Fund's largest single holding at
the end of the fiscal year, while we also continued to hold both Transocean and
Phelps Dodge. Other investments that added to returns include: NCR, which
develops and produces electronic processing equipment; Becton, Dickinson, a
medical products company, Occidental Petroleum, an integrated petroleum company;
and Providian Financial, which specializes in credit cards. The Fund still owned
these stocks at the period's end. Two holdings were the subjects of acquisitions
at premiums to their stock valuations, significantly helping performance.
Charter One Financial, which operates banks in nine Eastern and Midwestern
states, was acquired by Citizens Financial, a subsidiary of the Royal Bank of
Scotland. Apogent Technologies, which produces devices and equipment for
clinical and research laboratories, was purchased by Fisher Scientific
International.

Q: What were some of the investments that detracted from performance?

A: In addition to the Fund's defensive positioning in the financial services
sector and lack of exposure to REITs, performance relative to the benchmark
Russell Midcap Value Index was hurt by not owning several strongly performing
stocks, notably TXU, a Texas based utility, and Apple Computer. Other
investments that proved to be disappointments for the fiscal year included: PMI
Group, an insurer of residential mortgages and Mattel, the toy company.

Q: What is your investment outlook?

A: We are reasonably optimistic about the economy and investment opportunities
in the stock market. The economy is expanding at a healthy rate, job growth has
begun to accelerate, interest rates remain low by historical standards, and
inflation continues to be restrained. Stock valuations also appear to be
reasonable, giving us the opportunity to find interesting investments. Although
we expect to continue to de-emphasize the stocks of companies that may be
vulnerable to rapid increases in interest rates, we are moderately bullish about
the overall market.

Investing in mid-sized companies may offer the potential for higher returns, but
these companies are also subject to greater short-term price fluctuations than
larger, more established companies.

Portfolio Management Discussion 12/31/04

In the following interview, Michael Rega and Diego Franzin, co-managers of
Pioneer Growth Opportunities Fund, discuss the factors that influenced
performance for the twelve months ended December 31, 2004. The current portfolio
team assumed the Fund's management duties on December 10, 2004.

Q:  What factors affected the performance of U.S. equities during the past year?

A: The stock market performed very well in 2004, despite a potentially
challenging environment. Investors had to contend with a host of obstacles
throughout the year, including a sharp increase in oil prices, rising short-term
interest rates, the uncertainty associated with the U.S. presidential election
and the ongoing insurgency in Iraq. Nevertheless, the market remained well
supported by its strong underlying fundamentals. The economy continued to grow
at a steady pace, but not so fast that the Federal Reserve felt compelled to
accelerate its measured pace of rate increases. Corporate earnings also remained
robust, finishing the year at a much higher level than most analysts had
anticipated. Strong earnings, in turn, translated to increased dividends and a
continued improvement in corporate balance sheets. Taken together, those factors
helped the stock

                                      C-16


market climb the "wall of worry" and post a double-digit gain for the year. Amid
this generally positive environment, small-cap stocks outperformed their
large-cap counterparts by a wide margin, reflecting the superior earnings growth
of companies in the asset class. Within small-caps, value outperformed growth:
for the year, the Russell 2000 Value Index returned 22.25% versus 14.31% for the
Russell 2000 Growth Index. Given the Fund's focus on reasonably valued small-
and medium-sized companies, the strong returns within those market segments
provided a favorable tailwind to performance.

Q: How did the Fund perform in relation to its benchmark and peer group?

A: Class A shares of the Fund produced a total return of 22.23% at net asset
value during the twelve-month period ended December 31, 2004, compared to a
return of 18.33% for its benchmark, the Russell 2000 Index. The Fund also
outperformed the 18.38% average return of the 556 funds in the Lipper Small-Cap
Core category, finishing in the top quarter of the group.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Q: As new managers of the Fund, what changes do you anticipate making to the
   portfolio and its overall investment style?

A: We do not plan to do a major rebalancing of the portfolio, but we expect to
make a series of gradual changes to the Fund throughout the year as market
conditions warrant. First, we intend to bring greater diversification to the
portfolio by owning more stocks and taking smaller positions in individual
names. Second, we plan to keep the Fund sector neutral, meaning that its
industry weightings will usually be very closely in line with those of the
benchmark index. In this way, the majority of the Fund's performance will be the
result of individual stock selection. We believe we can add more value through
company research than by attempting to predict the direction of the overall
market or the relative performance of specific industries.

Q: How do you intend to select stocks for the Fund?

A: We start by dividing the Russell 2000 Index into a number of distinct sectors
and subsectors, then we use a disciplined stock selection model to identify the
most attractive stocks in each sector based on four factors: growth, quality,
valuation and momentum. That enables us to analyze the entire universe of 2,000
companies and select what our criteria show to be the top 20% in each sector.
Next, we focus our research capabilities to conduct a fundamental analysis of
each stock that has been selected. We believe that the approach provides both
breadth and depth to our stock picking. We believe that this investment style
will provide more stability to the portfolio and reduce the extent of the
variation in its return with respect to the benchmark index. Our goal is not to
hit home runs, but to hit singles and doubles and, in the process, try to
deliver market-beating returns on a long-term basis. MANAGEMENT DISCUSSION
12/31/04 (continued)

Q: What is your overall view of the market at this juncture?

A: We believe a focus on individual stock selection will be critical in the year
ahead. Small-caps have outperformed large-caps for six years in a row, which
suggests that a change in market-cap leaders may be in order. What's more, our
analysis shows that on a historical basis, growth stocks have been this
inexpensive in relation to value less than 5% of the time. This has two
implications: first, it means that gains in the small-cap value area are not
likely to come as easily as they did in 2004. As a result, fundamental research
should play a very important role in generating outperformance. Second, it means
that in assessing the outlook for individual stocks, we will place a higher than
normal emphasis on companies with the most attractive growth characteristics. We
believe these steps will help the Fund effectively navigate the year ahead even
in the event that the stellar relative performance of the small-cap value asset
class begins to cool off.

Q: In what areas are you finding the best investment opportunities?

A: In 2004, every major sector in the Russell 2000 Index provided double-digit
returns with the exception of technology. We expect a greater dispersion of
returns in 2005, which again would work to our advantage as individual stock
pickers. We will be looking for opportunities in technology and health care, two
areas that underperformed the broad-based index during 2004. One of the Fund's
top holding, MICROS Systems, is a tech stock that in our view is among those
that have additional upside. MICROS develops and markets software applications
to the hospitality industry, mostly table service restaurants. Their software
allows restaurants to improve coordination between servers and kitchen staff and
reduce costs by improving inventory

                                      C-17


management and product reordering. A key driver of future growth is expansion
into the hotel industry as the industry embarks on a 5- to 7-year technology
infrastructure upgrade cycle. Within health care, we will be closely looking for
opportunities in the biotechnology sector. We believe biotechs are less risky
than in the past, since there are more companies that have been public for four
or five years and, therefore, have a longer earnings history and more
experienced management teams. We will look to capitalize on companies we
identify as quality managed and staffed, along with a proven record of
execution. On the other side of the coin, we find the consumer staples and real
estate areas to be less compelling. And within financials, we intend to focus on
companies that have an asset/liability mix that favors a flattening yield curve
environment and exposure to expanding markets such as Florida and Texas.

Q: Do you have any final thoughts for investors?

A: We believe that the most important aspect of asset management is individual
stock selection, and we will remain committed to our research-driven approach.
Regardless of the direction of the overall market, we believe Fund shareholders
have the potential to benefit from our efforts to identify the highest-quality
small-cap stocks in the market. By concentrating on one industry or on a group
of related industries, the portfolio is more susceptible to adverse economic,
political or regulatory developments affecting those industries than is a
portfolio that invests more broadly. Investing in foreign and/or emerging
markets securities involves risks relating to interest rates, currency exchange
rates, economic, and political conditions. Investing in small companies may
offer the potential for higher returns, but these companies are also subject to
greater short-term price fluctuations than larger, more established companies.

or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These statements should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

Portfolio Management Discussion  1/31/05

In the following interview, portfolio manager Peng Chen, Chief Investment
Officer for Ibbotson Associates, discusses the market environment and investment
strategies that applied to the three portfolios in the Pioneer Ibbotson
Allocation Series for the period of almost six months since they began
operations on August 9, 2004.

Q: Could you characterize the economic backdrop against which the three
   portfolios began investment operations?

A: The period of nearly six months between the August 9, 2004 launch of the
funds and the end of January 2005 was an uncertain environment for investors.
While the U.S. economy has continued the growth trend that started in the second
half of 2003, the rate of growth has showed signs of decelerating. At the same
time, inflation continues to be a concern, spurred on by the continued strength
in the economy and, to a lesser extent, by oil prices that have been at all-time
highs. On the interest rate front, the Federal Reserve began to raise short-term
rates earlier in 2004 and appears to be maintaining a tightening policy to keep
economic growth in check.

Q: How did the financial markets respond in this climate?

A: Early in the period, equity market levels wavered while basically staying
within a range. As the November 2 date for the U.S. presidential election drew
closer, however, investors became increasingly focused on the accompanying
uncertainties, and

                                      C-20


stocks fell. In contrast, bond prices generally showed strength during this
time. The trends appeared to reverse themselves in the aftermath of the
election. The stock market responded positively to the increased clarity, while
bond market performance was dampened by expectations of a continued lack of
progress on reducing federal budget deficits.

Q: What were the strategic considerations that you applied to the three
   portfolios in allocating assets?

A: As the three portfolios in the series were launched and initial investor
dollars were received, assets were invested in keeping with the respective broad
asset allocation and specific mutual fund targets established prior to the
launch of the series. Toward the, middle of the period, in late October, we
implemented two strategic changes across all three portfolios. First, within the
U.S. stock portion of the portfolios, we implemented a moderate emphasis on
value stocks and a corresponding underweighting of more growth-oriented
investments. We did this because we believe the U.S. economy has entered into a
decelerating growth cycle that should favor value equities with relatively
stable earnings prospects. We also believe that the potential for higher
inflation and interest rates favors the value investment style over growth. Our
equity valuation and momentum models further support this assessment, indicating
an overweighting of value and an underweighting of growth equities. That said,
value stocks have now outperformed growth over a period of more than four years.
If the economy starts to show signs of more rapid growth, an overweighting of
more growth-oriented investments will be warranted. With respect to the other
equity asset classes, the portfolios' targeted exposure across large-, mid-, and
small-cap equities remained unchanged. We have also maintained neutral target
weightings in the non-U.S. equity market alternatives, both developed and
emerging. The other shift has been within the bond portion of the portfolios,
where we implemented an underweighting of the long-term bond vehicle, with the
difference allocated to the shorter-term fixed income alternative. We believe
that, given the prospect of higher interest rates across all maturities, but
especially on the long end of the yield curve, shorter duration fixed-income
investments are more attractive. Elsewhere within fixed-income, we have
maintained neutral positions in the high yield bond offering, as well as in the
non-U.S. fixed-income option. Going forward, we will closely monitor economic
indicators and interest rate movements to evaluate whether we need to make any
adjustments to the views underlying these allocations. Given the significant
level of uncertainty that continues to impact the financial markets, we believe
that maintaining appropriate diversification across asset classes will be
especially important in the months ahead.

Please the see the Portfolio Reviews beginning on page 10 for information on
specific weightings and performance for each of the three portfolios in the
Pioneer Ibbotson Asset Allocation Series. Any information in this shareholder
report regarding market or economic trends or the factors influencing the Fund's
historical or future performance are statements of the opinion of Fund
management as of the date of this report. These statements should not be relied

                                      C-26


A: Early in the period, equity market levels wavered while basically staying
within a range. As the November 2 date for the U.S. presidential election drew
closer, however, investors became increasingly focused on the accompanying
uncertainties, and stocks fell. In contrast, bond prices generally showed
strength during this time. The trends appeared to reverse themselves in the
aftermath of the election. The stock market responded positively to the
increased clarity, while bond market performance was dampened by expectations of
a continued lack of progress on reducing federal budget deficits.

Q: What were the strategic considerations that you applied to the three
   portfolios in allocating assets?

A: As the three portfolios in the series were launched and initial investor
dollars were received, assets were invested in keeping with the respective broad
asset allocation and specific mutual fund targets established prior to the
launch of the series. Toward the, middle of the period, in late October, we
implemented two strategic changes across all three portfolios.

First, within the U.S. stock portion of the portfolios, we implemented a
moderate emphasis on value stocks and a corresponding underweighting of more
growth-oriented investments. We did this because we believe the U.S. economy has
entered into a decelerating growth cycle that should favor value equities with
relatively stable earnings prospects. We also believe that the potential for
higher inflation and interest rates favors the value investment style over
growth. Our equity valuation and momentum models further support this
assessment, indicating an overweighting of value and an underweighting of growth
equities. That said, value stocks have now outperformed growth over a period of
more than four years. If the economy starts to show signs of more rapid growth,
an overweighting of more growth-oriented investments will be warranted. With
respect to the other equity asset classes, the portfolios' targeted exposure
across large-, mid-, and small-cap equities remained unchanged. We have also
maintained neutral target weightings in the non-U.S. equity market alternatives,
both developed and emerging. The other shift has been within the bond portion of
the portfolios, where we implemented an underweighting of the long-term bond
vehicle, with the difference allocated to the shorter-term fixed income
alternative. We believe that, given the prospect of higher interest rates across
all maturities, but especially on the long end of the yield curve, shorter
duration fixed-income investments are more attractive. Elsewhere within
fixed-income, we have maintained neutral positions in the high yield bond
offering, as well as in the non-U.S. fixed-income option.

Going forward, we will closely monitor economic indicators and interest rate
movements to evaluate whether we need to make any adjustments to the views
underlying these allocations. Given the significant level of uncertainty that
continues to impact the financial markets, we believe that maintaining
appropriate diversification across asset classes will be especially important in
the months ahead.

specific weightings and performance for each of the three portfolios in the
Pioneer Ibbotson Asset Allocation Series. Any information in this shareholder

Portfolio Management Discussion   12/31/04

As the domestic economy showed evidence of a sustained recovery during the
second half of 2004, the U.S. Federal Reserve continued to raise short-term
interest rates gradually to contain the risk of inflation and keep the economy
in check. The fixed-income market reacted favorably to the Fed's series of
measured increases in the Fed funds rate, with the yields of longer-term
Treasuries actually declining modestly. Meanwhile corporate bonds and mortgages
continued to outperform Treasuries as investors sought out higher-yielding
investments in an environment of low, by historical standards, interest rates.
In the following discussion, Kenneth J. Taubes discusses the factors that
influenced Pioneer Bond Fund's performance during the six months. Mr. Taubes,
Director of Pioneer's Fixed Income Group, oversees the team responsible for
daily management of the Fund.

Q: How did the Fund perform during six months ended December 31, 2004?

A: Pioneer Bond Fund performed well, outpacing its benchmark as well as the
competitive funds average. For the six-month period, the Fund's Class A shares
returned 4.92%, at net asset value. During the same six months, the Lehman
Brothers Aggregate Bond Index returned 4.18%, while the average total return of
the 224 funds in Lipper's Corporate Debt A-Rated Bond Fund category was also
4.18%. On December 31, 2004, the standardized 30-day SEC Yield on Class A shares
was 4.00%. The performance data quoted represents past performance, which is no
guarantee of future results. Investment return and principal value will
fluctuate, and shares, when redeemed, may be worth more or less than their
original cost.

Q: What factors affected Fund performance?

                                      C-30


A: During a period in which investors sought out yield, the Fund held to its
emphasis on sectors with yield advantages over Treasuries, corporate bonds and
mortgage-backed securities. Both corporate bonds and mortgage securities
outperformed Treasuries, with high-yield corporate securities turning in the
best performance of all sectors of the domestic bond market. Despite rising
short-term rates, the yields of longer maturity Treasuries were relatively
stable, and investors sought out securities with yield advantages over
Treasuries. Against a backdrop of a strengthening economy, corporations
generated additional cash flow, which improved the overall credit quality of
corporate securities and further encouraged investments in both high-yield and
investment-grade corporate debt.

Our emphasis on high-yield and investment-grade corporate bonds as well as
mortgage securities helped support Fund performance throughout the six months.
At the end of the six-month period, about 55% of assets were invested in
mortgage securities and about 40% were invested in corporate debt, including
almost 15% high-yield bonds. We reduced our high-yield positions slightly in the
final quarter of the year. As we did so, we increased our investments in
mortgages, which offered yields competitive with investment-grade corporates but
with higher quality. Overall average credit quality of the portfolio was raised
slightly during the period from A to A+. Less significant but also helpful was
our decision to keep the Fund's sensitivity to interest-rate changes -- as
measured by duration -- either neutral or slightly longer than the benchmark
Lehman Brothers Aggregate Bond Index. In an environment of stable to
slightly-declining market interest rates, this strategy tended to benefit
performance. On December 31, 2004, the Fund's average effective duration was a
somewhat shorter 3.99 years.

Q: What were some of the individual holdings that most influenced portfolio
   performance?

A: Among the high-yield holdings that helped performance were the bonds of two
steel companies: International Steel, which we sold to take profits before the
period ended, and ISPAT Inland ULC, which were upgraded in credit rating after
the company was acquired by a Dutch corporation. Other bonds which appreciated
strongly in price were those of financial service corporates Allmerica
Financial, E-Trade and Odyssey Re. Detracting from results were insurance
company Provident, whose bond prices slipped amid controversy over the New York
attorney general's investigation of industry practices, Toys "R" Us, which
announced restructuring plans, and Intelsat, a satellite company that withdrew
plans for an initial public stock offering.

Q: What is your investment outlook?

A: We anticipate that the Federal Reserve will continue to raise the Fed funds
rate at a gradual pace during 2005. The fixed-income market already has
anticipated, in current bond prices, a series of further increases that would
bring the Fed funds rate from 2.25% to near 3.5% by the end of the year. We
believe the market rates of longer-term and intermediate-term securities already
are close to being fairly valued. As a result, we anticipate that the yield
curve -- which measures the relationship between short-term and longer-term
interest rates -- likely will flatten during the year as short-term rates move
up. In general, valuations of corporate securities appear relatively high by
historical standards, but they probably are justified given the strong economic
fundamentals both in the United States and throughout the globe. Strengthening
economies are now helping companies across all sectors, resulting in improved
cash flows and corporate profits. In this environment, we think corporate bonds
should perform well, consistent with their yield advantage over Treasuries. As a
result, we will continue to look for opportunities in the corporate sector.
However, we expect to also put greater emphasis on mortgage securities, which
offer virtually the same yields as investment grade corporate debt but have the
advantage of higher credit ratings.

Investments in high yield or lower-rated securities are subject to greater-than
average risk. When interest rates rise, the prices of fixed income securities in
the Fund will generally fall. Conversely, when interest rates fall the prices of
fixed-income securities in the Fund will generally rise. The portfolio may
invest in mortgage-backed securities, which during times of fluctuating interest
rates may increase or decrease more than other fixed-income securities.

Mortgage-backed securities are also subject to pre-payments. Investments in the
Fund are subject to possible loss due to the financial failure of underlying
securities and their inability to meet their debt obligations.

or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These statements should not be relied upon for any other purposes. Past

Portfolio Management Discussion   12/31/04

During a period when interest rates remained relatively low, Pioneer Tax Free
Income Fund's exposure to investments in a variety of states and a diverse
number of economic sectors provided an attractive level of tax-free income. In
the following interview, David Eurkus, a member of Pioneer's Fixed Income
Management Team, discusses some of the factors that had an impact on the
municipal bond market and your Fund.

Q: How did the Fund perform?

A: For the 12-month period ended December 31, 2004, Pioneer Tax Free Income
Fund's Class A shares produced a 4.75% total return at net asset value. The
Fund's benchmark, the Lehman Brothers Municipal Bond Index, returned 4.48%, and
the average return of the 297 funds in the Lipper General Municipal Debt Funds
Category was 3.70%. Lipper is an independent monitor of mutual fund performance.
The Fund's Class A shares generated a 30-day SEC tax-free yield of 3.88% on
December 31, 2004. That translates into a taxable equivalent yield of 5.97%,
based on the maximum federal income-tax rate of 35%. The performance data quoted
represents past performance, which is no guarantee of future results. Investment
return and principal value will fluctuate, and shares when redeemed, may be
worth more or less than their original cost.

Q: What was the investment environment like during the period?

A: Early in the period, the strength of the economic rebound raised concerns
that inflation and interest rates might rise. In this environment, there was a
significant decline in the bond market, which pushed bond prices down and yields
up. As the fiscal

                                      C-34


year progressed, however, reports associated with the economy indicated that the
rapid pace of growth had shifted to a slower but steady rate. Despite this
slight softening in the economic expansion, the Federal Reserve began tightening
monetary policy, boosting the Federal funds rate on five occasions, each time by
0.25%. By yearend, the Federal funds rate was 2.25%, up from 1.00% at the start
of 2004. (The Federal funds rate is the rate banks charge each other for
overnight loans.) Initially, the Fed's actions caused yields to move higher, but
when it appeared that inflation was under control, the yield curve flattened.
(The yield curve shows the relationship between bond yields and maturity
lengths.) With a flatter yield curve, short-term yields moved higher and prices
declined; and longer-term yields fell or remained stable, boosting bond prices.

Q: How did you manage the Fund in this environment?

A: We maintained a diverse portfolio with assets invested in 154 securities in
38 states. We continued to emphasize sectors that are vital to the growth of the
U.S. economy. These sectors included health care/hospitals, housing,
transportation, and power and energy, areas in which the underlying credit
quality of the fixed-income securities tends to improve as the economy gets
stronger. We also had a position in tobacco revenue bonds, which are
investment-grade securities that are backed by the tobacco settlement money
awarded to states. Most of the portfolio was invested in investment-grade
securities, those rated BBB or better. However, about 10% was allocated to below
investment-grade bonds, which had relatively high yields and which enhanced the
Fund's income stream. At the end of the period, the Fund's overall quality
rating was A+.

Q: What contributed most to performance?

A: As short-term interest rates went up, the portfolio benefited from the price
appreciation that resulted from the declining yields on longer-term securities.
In addition, the below investment-grade bonds in the portfolio helped boost the
tax-free income and prices.

Q: What detracted from performance?

A: There were no significant detractors. Overall the portfolio was positioned
for declining interest rates. Our duration could have been somewhat longer;
however, it exceeded the duration of our benchmark, the Lehman Brothers
Municipal Bond Index, and our peer group, the Lipper General Municipal Debt
Funds Category. (Duration measures a bond's sensitivity to interest-rate
changes. A shorter duration is helpful when interest rates rise, and a longer
duration is usually an advantageous when interest rates decline.)

Q: What is your outlook for the next six months?

A: We believe that the economy is on a positive growth path and expect the Fed
to continue making modest interest-rate hikes over the near term. Therefore, we
expect short-term rates to move higher and long-term rates to remain stable or
possibly decline. In this environment, income could become a larger component of
performance.

A portion of income may be subject to state, federal, and/or alternative minimum
tax. Capital gains, if any, are subject to a capital gains tax. A portion of
income may be subject to state, federal, and/or alternative minimum tax. Capital
gains, if any, are subject to a capital gains tax. When interest rates rise, the
prices of fixed income securities in the fund will generally fall. Conversely,
when interest rates fall the prices of fixed income securities in the fund will
generally rise. 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. Investments in the fund are subject to possible loss due
to the financial failure of underlying securities and their inability to meet
their debt obligations. Any information in this shareholder report regarding

Portfolio Management Discussion   12/31/04

As the U.S. economy expanded, the Federal Reserve began raising interest rates
at a slow but steady pace. Short-term interest rates rose more than long-term
rates, which remained virtually unchanged for the year. For example, at the
beginning of the year, the yield on the two-year Treasury was 1.82%. At the end
of the year, it was 3.07%. The yield on the 10-year Treasury began the year at
4.25% and ended the year at 4.22%. Against this backdrop, investors in U.S.
Government and agency securities were rewarded with a relatively attractive
level of income during the 12-month period ended December 31, 2004. In the
interview below, Richard Schlanger, a member of the Pioneer fixed-income team,
discusses the factors that affected the fixed-income market and the Trust over
the past 12 months.

                                      C-37


Q: How did the Trust perform during the period?

A: For the 12-month period ended December 31, 2004, Class A shares of Pioneer
America Income Trust produced a total return of 2.77% at net asset value. The
Trust underperformed its benchmark, the Lehman Brothers Government Bond Index,
which returned 3.48% for the same period. The Trust also underperformed the
Lehman Brothers Fixed-Rate Mortgage-Backed Index, which returned 4.70%. We
attribute the shortfall relative to the Lehman Brothers Fixed-Rate
Mortgage-Backed Index to the index's significant exposure to securities issued
by the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal
National Mortgage Association (Fannie Mae), which outperformed Ginnie Maes.
Because conventional mortgages--those issued by Freddie Mac and Fannie Mae--do
not have the backing of the full faith and credit of the U.S. Government, we do
not invest in them. The Trust underperformed the 3.19% return generated by the
General U.S. Government Funds Category of Lipper, an independent monitor of
mutual fund performance. At the end of the period, the 30-day SEC yield for
Class A shares was 3.25%. The performance data quoted represents past
performance, which is no guarantee of future results. Investment return and
principal value will fluctuate, and shares, when redeemed, may be worth more or
less than their original cost.

Q. What was the investment environment like during the period?

A. The economy continued to gain strength in 2004, reflected by improving job
growth, relatively strong consumer spending, and higher commodity and oil
prices. With the economy on a firmer footing, the Federal Reserve boosted
short-term interest rates in June and continued raising them through the end of
the year. By year-end, the federal funds rate was 2.25%, up from 1.00% at the
start of 2004. (The federal funds rate is the rate banks charge each other for
overnight loans.) Initially, the Fed's actions caused Treasury yields to move
higher but when it appeared that inflation was under control, the yield curve
flattened. The yield curve shows the relationship between bond yields and
maturity lengths. With a flatter yield curve, short-term yields moved higher and
prices declined; longer-term yields fell or remained stable, boosting prices. An
enormous amount of Treasury buying by overseas investors was also instrumental
in keeping Treasury yields low. Foreign central banks had large cash reserves,
which they invested at record levels in the U.S. Treasury market in an attempt
to stem the decline of the U.S. dollar relative to their own currencies.

Q: How did you manage the Trust in this environment?

A: The Trust was divided between mortgage-backed securities, which accounted for
70.6% of net assets, and Treasury securities, which composed 28.2% of net
assets. The Trust also had a 1.2% cash position. In the mortgage market, we
invested in securities issued by the Government National Mortgage Association
(GNMA), which are backed by the full faith and credit of the U.S. government. (A
full faith and credit backing applies to underlying Trust securities, not to
Trust shares). Because interest rates remained attractive and the housing market
was strong, we sought to avoid prepayment risk. When interest rates decline,
homeowners often "prepay" their existing mortgages and refinance their homes at
a lower rate. Significant prepayment activity can result in declining yields and
share prices in portfolios with investments in mortgages. To mitigate this risk,
we favored mortgages with low loan balances that were not likely to be
refinanced. We also emphasized mortgage pools in slow-paying states, such as New
York and Texas, where the rate of housing turnover is relatively low in
comparison to other states. In addition, we sought mortgages with coupons
(stated rates of interest) in the 4.5% to 5.5% range, which would probably not
be refinanced quickly. In the Treasury portion of the Trust, we emphasized
securities with short to intermediate durations. We expected yields to move
higher and wanted to minimize the price volatility that would naturally occur as
yields rose. Therefore, we kept duration shorter than the benchmark. Measured in
years, duration measures a bond's price sensitivity to interest-rate changes. A
shorter duration can protect a portfolio from price declines as yields rise. We
were premature, however, in our expectation of higher yields. As a result, our
short-duration strategy worked against the Trust. Long-term Treasuries
outperformed, because of the huge demand from overseas investors and the
flattening of the yield curve. For example, the 30-year Treasury bond returned
8.89%; the five-year Treasury returned 2.39%.

Q: What contributed most to performance?

A: The significant overweight in mortgage-backed securities made the largest
positive impact, as mortgages outperformed other fixed income assets. Minimizing
prepayment risk by selecting specific mortgage pools also helped drive
performance. The flatter yield curve, which boosted the prices of longer-term
Treasury securities, also benefited results.

Q: What detracted from performance?

                                      C-38


A: The Trust's underweight in long-term Treasuries. We continue to believe,
however, that yields on such Treasuries are artificially low, given the weak
U.S. dollar, the growing trade imbalance and a Fed that is likely to continue
raising interest rates.

Q: What is your outlook for the next six months?

A: In the short term, we expect the investment environment to remain unchanged
and are unlikely to alter the Trust significantly during the first quarter of
2005. We plan to continue to emphasize mortgage securities. In February, Federal
Reserve Chairman Alan Greenspan will make his semi annual Humphrey-Hawkins
testimony before Congressional committees. At that time, we will learn what to
expect in the way of Fed interest-rate policy and what the central bank's
thinking is about the prospects for accelerating inflation. Whenever the Fed
raises rates, there is a lag effect; and it can take as long as a year for
higher rates to affect the economy. Over the next several months, we will be
closely monitoring data to determine the appropriate action to take should the
economic backdrop change.

Government guarantees apply to the underlying securities only and not to the
prices and yields of the portfolio. When interest rates rise, the prices of
fixed income securities in the fund will generally fall. Conversely, when
interest rates fall the prices of fixed income securities in the fund will
generally rise. The portfolio may invest in mortgage-backed securities, which
during times of fluctuating interest rates may increase or decrease more than
other fixed-income securities. Mortgage-backed securities are also subject to
pre-payments. Investments in the fund are subject to possible loss due to the
financial failure of underlying securities and their inability to meet their
debt obligations.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Trust's historical or future performance are
statements of the opinion of Trust management as of the date of this report.
These statements should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

Portfolio Management Discussion   2/28/05

In the following interview, Richard Schlanger, the Fund's Lead portfolio
Manager, discusses the factors that influenced performance for the semiannual
period ended February 28, 2005.

Q. How would you characterize the market environment for fixed- income investors
over the six-month period?

A. On balance, the economy continued to show evidence of solid growth, although
some of the employment statistics have not been as robust as in past recoveries.
Given this backdrop, the Federal Reserve continued to execute a "measured"
approach to removing its accommodative stance with respect to short-term
interest rates. This took the form of three separate hikes in the benchmark fed
funds rate (the interbank overnight lending rate) totaling three-quarters of a
percentage point over the period.

While long-term interest rates were relatively stable, shorter-term bonds
experienced yield increases - and corresponding price declines - over the
period. Yields on shorter-maturity issues rose substantially over the period,
with both the six-month and two-year Treasuries experiencing yield increases of
just over one percentage point. By contrast, long-term interest rates ended the
period only slightly higher than where they began, with the ten-year Treasury
yield increasing approximately one-quarter percentage point.

Q. How did the Fund perform in this environment?

A. The Fund's total return from August 31, 2004, through February 28, 2005 was a
positive 0.12%, versus -0.16% for the unmanaged benchmark index, the Lehman
Brothers One-to Three-Year Government/Credit Index. The return number is for
Class A shares and does not include the impact of any sales charge paid.

Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent month-end
performance results. Current performance may be lower or higher than the
performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and Pioneer Short Term Income Fund
principal value will fluctuate, and shares, when redeemed, may be worth more or
less than their original cost.

The Fund also continued to deliver good income. The 30-day SEC yield for Class A
shares on February 28, 2005, was 2.47%. This yield reflects the waiver of
certain expenses by the investment advisor; without the waiver, the 30-day SEC
yield for Class A shares would have been 1.99%.

The Fund's absolute return for the six-month period primarily reflects a
difficult environment for short-term bonds, as yields increased and prices
generally fell among these issues.

We believe the Fund's comparatively better performance versus its benchmark
index can be attributed to a combination of:

   1. shorter overall portfolio duration - a measure of interest rate
sensitivity - which helped cushion against pervasive
price declines;

                                      C-43


   2. security selection favoring mortgage pass-through securities, an area of
the bond market that outperformed Treasury securities.

Q. What is your outlook?

A. We continue to believe that, despite some underlying strain, the global
economy is on a path of solid growth, led by the United States, which appears
positioned to deliver GDP growth in the 3.5% to 4.0% range for the
near-to-intermediate term. Growth at this level would support solid expansion in
employment over time and could put some upward pressure on inflation and
interest rates. In addition, the decline of the U.S. dollar and continued high
oil prices both suggest that a rise in inflation would not be surprising, with a
corresponding impact on interest rates. Finally, the lack of progress in
reducing the U.S. budget deficit may also lead to rising interest rates over
time. With respect to short-term rates, we expect the Fed to continue on a
course to raise rates gradually over the next year or so in an effort to contain
potential inflationary pressures while allowing the economy to continue on its
current growth path.

Q. How is the Fund currently positioned?

A. In view of our outlook for continued solid economic growth, the Fund is
somewhat conservatively positioned from the perspective of sensitivity to
changes in interest rates. At the end of February, the Fund's weighted average
maturity was 1.38 years, well under the Fund's maximum of three years.

Average quality of the Fund's portfolio is currently a high "AA." We continue to
maintain broad exposure to a number of areas of the bond market, while seeking
to identify and benefit from relative value among sectors. Currently, yield
differentials are quite narrow among sectors on the short end of the curve. For
instance, high-quality corporates offer less than half of a percentage point of
additional yield versus Treasuries of comparable maturity. At the end of
February, our weighting in corporate bonds accounted for about 22% of Fund
assets, at the low end of our anticipated range.

Nearly 35% of the Fund's assets are invested in mortgage pass-through
securities, down from approximately 40% at the beginning of the period, again
reflecting our view on relative value. Our holdings among pass-throughs are
focused on "balloon" mortgages with shorter maturities, as well as
collateralized mortgage obligations that we believe carry low risk of
experiencing a slowing of prepayments (and corresponding increase in duration.

U.S. Treasury issues totaled about 32% of assets at period end, including a
small position (approximately 3.7%) in short-term "STRIPS" or "zero coupon"
bonds. STRIPS are purchased at a discount to face value and redeemed at par
value upon maturity, and the position is anticipated to provide an additional
measure of support for the Fund's share price.

Going forward, we will continue to seek to provide a high level of current
income while maintaining a relatively stable share price. While the Fund's share
price will fluctuate, our focus on shorter-term bonds is designed to reduce
price volatility in comparison to longer term alternatives. We believe the
Fund's high quality and limited exposure to interest-rate changes makes it an
attractive option for investors seeking to maintain important fixed-income
exposure in an uncertain environment.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
When interest rates rise, the prices of fixed income securities in the Fund will
generally fall. Conversely, when interest rates fall the prices of fixed income
securities in the Fund will generally rise. Investments in the Fund are subject
to possible loss due to the financial failure of underlying securities and their
inability to meet their debt obligations.

Portfolio Management Discussion  12/31/04

Although the U.S. Federal Reserve started to raise short-term interest rates
from the lowest levels reached in more than four decades, 2004 remained a year
in which money market investments offered extremely low yields by historical
measures. Despite five increases in interest rates between June 30 and December
31, the key Fed Funds Rate ended the year at just 2.25%. Throughout the 12
months ended December 31, 2004, Pioneer Cash Reserves Fund maintained a $1 share
price and provided modest income consistent with the yields available in the
money market. The Fund invests exclusively in high quality money market
instruments issued by the U.S. government and domestic corporations and banks.
All issues have the highest ratings from the two nationally recognized ratings
organizations: A1 by Standard & Poor's Investors Services and P1 by Moody's
Investor Services. (Ratings apply to underlying securities, not Fund shares.) In
the following discussion, Andrew D. Feltus reviews the investment environment
and the strategies that affected Pioneer Cash Reserves Fund over the 12 months
ended December 31, 2004. Mr. Feltus is a member of Pioneer's Fixed Income Group,
which is responsible for the daily management of the Fund.

Q: How did the Fund perform during 2004?

A: For the 12 months ended December 31, 2004, Class A shares of Pioneer Cash
Reserves Fund had a total return of 0.45%, at net asset value. On December 31,
2004, the Fund's seven-day effective yield for Class A shares was 1.13%. For the
12 months, the average total return among the 395 funds in Lipper's Money Market
Fund category was 0.60%. The performance data quoted represents past
performance, which is no guarantee of future results. Investment return and
principal value will fluctuate, and shares, when redeemed, may be worth more or
less than their original cost.

Q: What was the investment environment like during the year?

A: For virtually the entire first half of 2004, the influential Fed Funds Rate
remained at a 46-year low of 1.00%. The situation began to change when the
Federal Reserve raised the rate on June 30 by one-quarter of one percentage
point and signaled that it intended to initiate further increases on a gradual
basis. The central bank raised the rate four more times, and the Fed Funds Rate
stood at 2.25% at the end of the year. The rate increases occurred against a
backdrop of continued economic growth and hints of an increase in inflationary
pressure. Economic growth, as measured by growth in Gross Domestic Product
(GDP), rose by an average annualized rate of 4.6% during the first nine months
of 2004. Affected by the higher costs of energy, the Consumer Price Index rose
to about 3.5% by the end of November. While periodic concerns about low new-job
creation did arise, in general the Federal Reserve Board believed that the
economy was gathering enough strength that monetary policy could be tightened to
avert the possibility of increasing inflationary threats. At the end of the
year, the Federal Reserve was widely expected to continue to raise short-term
rates further in 2005.

Q: What were your principal strategies in this low-interest rate environment?

A: We held to our commitment to high quality money market instruments. We
started gradually to lower the Fund's effective duration so that we could take
advantage of higher yields available as the Federal Reserve Board proceeded with
its rate increases. At the end of the year, the effective duration of the Fund
was 60 days, and we were moving to have a target duration of about 45 days as
the new year unfolded.

Q: What is your investment outlook?

A: We anticipate that the economy will show sustained growth in 2005 and that
the Federal Reserve Board will maintain its policy of raising short-term grates
gradually. At the same time, because of budget pressures and concern about the
federal deficit, the government is likely to put new brakes on spending. The
combination of the tighter monetary policy and restrained fiscal policy may act
as a drag on the pace of economic growth and ultimately cause a possible change
in monetary policy.

If economic growth does begin to slow, the Federal Reserve may revise its
current bias toward raising short-term rates. However, until that appears to be
imminent, we intend to continue to keep the Fund's effective duration relatively
short to enable us to invest in newer, higher-yielding securities that have the
potential to raise the level of income to be distributed to

Portfolio Management Discussion 12/31/04

On August 2, 2004, Pioneer Investments assumed management of the former Safeco
Funds. In the following interview, David Eurkus, a member of the fixed income
team, details the investment environment for tax-free money funds during the
12-month period ended December 31, 2004, the Fund's performance for the period,
and the Fund's portfolio strategy going forward.

Q: Will you describe what, if anything, has changed and what has remained the
   same in the transition of Fund management to Pioneer?

A: As a Safeco product, and now as Pioneer Tax Free Money Market Fund, this has
been and will continue to be a very conservative offering. We are keeping the
Fund as a high quality, liquid product. We will not compromise stability of
principal in any way by taking on additional risk to secure a more competitive
yield than our peers. Safety of principal is paramount and, as part of the
objective, we will continue to seek tax-free income for the Fund's shareholders.

                                      C-48


Q: How did the Fund perform during its most recent fiscal year?

A: For the 12-month period ended December 31, 2004, the Fund's Class A shares
posted a 0.58% total return at net asset value. (The performance of each class
of the Fund is the performance of the predecessor fund's Investor Class, which
has been restated to reflect differences in any applicable sales charges (but
not Rule 12b-1 fees or other differences in expenses). If all the expenses of
the Pioneer fund were reflected, the performance would be lower.) In comparison,
the Lipper Tax-Exempt Money Market Average returned 0.56%. The performance data
quoted represents past performance, which is no guarantee of future results.
Investment return and principal value will fluctuate, and shares, when redeemed,
may be worth more or less than their original cost.

Q: Will you describe the investing environment for tax-exempt money funds during
   the time period?

A: Prior to June 2004, short- and long-term interest rates had continued to fall
since the stock market bubble burst in 2001. Early last year, one-year tax-free
money market rates fell as low as 0.50%. Then, as the U.S. economy began to show
modest improvement in the first half of 2004, the Federal Reserve indicated that
the economy and job growth were showing signs of improvement and that the Fed
was becoming more concerned about the possibility of rising inflation rather
than deflation. The Fed also hinted that it would begin to raise short-term
interest rates in the second half of 2004, but at a "measured" pace. The Fed
then raised short-term interest rates by 25 basis points at each of its five
meetings in the second half of the year. As a result, the one-year Bond Buyer
Index, the market's measurement of tax-exempt money market rates, rose from
0.50% at the start of the year to 1.25% at year end. Historically, those are
still extremely low rates. Supply and demand for tax-exempt money market
securities continue to be well balanced. This is evidenced by the still
significant amount of assets being held in taxable as well as tax-free money
market funds. Investor demand continues to be substantial, and there is ample
supply to deal with the asset base.

Q: What has been your strategy since assuming management of the Fund last
   August?

A: We continue to maintain broad diversification, both on a regional and
national basis, with AAA credits in revenue as well as general obligation
issues. As a Seattle-based fund, the previous Safeco product was regionally
focused, with investments based in Colorado, Texas and Alaska as its top three
portfolio concentrations. As we continue to emphasize safety of principal we
will be changing to a more nationally focused diversification strategy. The Fund
invests in floating rate securities (55% of portfolio assets as of December 31,
2004) as well as fixed-rate instruments (45% of assets). The interest rate of
floating rate securities adjusts periodically based on indices such as the Bond
Buyer Index and the Fed funds rate. As of December 31, the Fund's effective
maturity was 56 days. With the Fed's series of short term interest rate
increases, the yield curve is changing, and we will adjust the portfolio
accordingly. As some six- and 12-month securities in the portfolio mature we are
converting them to cash in anticipation of further short-term interest rate
increases. That will gradually decrease the Fund's weighted average maturity in
the short term. Over the long term this strategy should benefit shareholders
because we will be reinvesting at higher rates than the yields that are
currently available. In terms of portfolio quality, over 90% of the portfolio is
AAA-rated, with the balance rated AA. (Ratings apply to underlying securities,
not Fund shares.)

Q: What is your outlook?

A: In the months ahead, we foresee continued modest growth in the U.S. economy.
We also think that the Fed will maintain its bias for measured increases in
short-term interest rates over the next several months. A portion of income may
be subject to state, federal, and/or alternative minimum tax. Capital gains, if
any, are subject to a capital gains tax. Investing in foreign and/or emerging
markets securities involves risks relating to interest rates, currency exchange
rates, economic, and political conditions. When interest rates rise, the prices
of fixed income securities in the Fund will generally fall. Conversely, when
interest rates fall the prices of fixed income securities in the Fund will
generally rise. Although the Fund seeks to preserve the value of your investment
at $1.00 per share, it is possible to lose money by investing in the Fund. Fund
shares are not federally insured by the Federal Deposit Insurance Corporation,
the Federal Reserve Board or any other government agency.

PORTFOLIO MANAGER

Brian B. Sullivan, CFA
Director, Value Equity Strategies


AmSouth Bank
AmSouth Asset Management, Inc.

Brian Sullivan has been the portfolio manager for the AmSouth Value and AmSouth
Balanced Fund since June 2004. Mr. Sullivan has more than 18 years of investment
management experience and holds an MBA in finance and a bachelor's degree in
economics.


INVESTMENT CONCERNS

Value-based investments are subject to the risk that the broad market may not
recognize their intrinsic value.

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.


- --------------------------------------------------------------------------------
PORTFOLIO MANAGER'S PERSPECTIVE

"The AmSouth Value Fund uses a 'value investing' approach. Rather than pursue
hot stocks that are in high demand, we search for solid companies with good
fundamentals that are available that attractive prices. By adhering to this
investment approach through entire market cycles, we seek to achieve above
average long-term results with less volatility than the overall market."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 11.37% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 10.47% total return for the Fund's benchmark, the S&P
500/BARRA Value Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the period ended
January 31, 2005, were 5.27%, 4.36%, 1.77% and 9.18%, respectively, for Class A
Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder
would pay on distributions and redemptions. The investment return and principal
value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. A favorable backdrop, characterized by economic growth, the resolution of the
presidential election and a pullback in oil prices, helped stocks rally during
the fourth quarter of 2004. Value stocks performed particularly well, boosting
this Fund's returns

Stock selection produced the largest contribution to the Fund's relative
performance. Strong performance by particular stocks in the restaurant and
retail industries helped the Fund's consumer- discretionary stocks outperform
the corresponding sector in the index.


                                       2


The Fund's relative returns also benefited from our strategy in the energy
sector whereby we reduced the Fund's energy holdings during the period as prices
on energy stocks increased. That strategy boosted performance against the
benchmark, as energy stocks declined late in the period in response to falling
oil prices. +

The Fund held an underweight position in utilities stocks during the period.
That stake weighed slightly on relative returns, as utilities stocks led the
benchmark. The reverse was true for performance data quoted represents past
performance telecommunications services stocks. We over-weighted that sector,
and current returns may be lower or higher. Total return so its relatively weak
performance modestly reduced the Fund's figures include change in share price,
reinvestment of return relative to the returns of the benchmark. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

economics, and Janna holds an MA in economics. They have worked together for the
past 12 years. They also serve as the portfolio managers for the AmSouth
Enhanced Market Fund and the AmSouth Mid Cap Fund.

INVESTMENT CONCERNS

A concentrated portfolio may add a measure of volatility to performance, as
major fluctuations in any one holding will likely affect the fund more than a
fund with a greater diversification.

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"Our goal in managing the AmSouth Select Equity Fund is to outperform the S&P
500 Stock Index(1) over a complete market cycle while experiencing less
volatility than the broad stock market. We look for 20 to 25 leading companies
that have a dominant market position, or well-known brand name, yet whose stock
price is undervalued. To make this 'growth at a reasonable price' strategy work,
we use economic theory to determine whether a company is likely to recover its
dominant position after a dip. We believe our patient, long-term approach offers
excellent defensive protection, which can reduce losses when the market is
weak."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 8.94% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower), compared to a 8.15% total return for its benchmark, the S&P 500 Stock
Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and Since Inception (9/1/98) average annual total returns for the
period ended January 31, 2005, were 2.92%, 1.41%, 8.79% and 6.94%, respectively,
for Class A Shares. The returns quoted assume the reinvestment of dividends and
capital gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder

value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. Large-cap stocks generated gains during most of the period, which included a
strong rally during November and December. That environment helped the Fund and
its benchmark produce positive returns.

This Fund's sub-advisor, OakBrook Investments, invests in select shares of
industry-leading companies with steady and predictable earnings growth. We
believe the Fund's managers positioned the portfolio to benefit from an economic
recovery, while avoiding exposure to stocks that were likely to be hurt by
rising interest rates.


                                       4


That strategy helped the Fund stay even with the market during the first five
months of the period, as short-term interest rates increased and a cyclical
pick-up did occur. A decline in long-term interest rates offset some of the
benefits of the managers' strategy, however. What's more, rising commodity
prices had a negative impact on the Fund's holdings. Shares of the
industry-leading firms in which this Fund invests tend to be consumers of
commodities, rather than producers of them, and therefore suffer from rising
commodity prices.+

The market experienced a sell-off in January. This Fund's holdings fared better
than the benchmark in that environment, and generated most of the Fund's
relative gains for the six-month period. This may reflect the fact that
investors during January prized the earnings stability and predictability that
this Fund emphasizes. +

+   The Fund's portfolio is current to January 31, 2005 and subject to change.

experience a widening range of investor expectations. We look to overweight

helped the Fund and its benchmark generate positive returns.

This Fund's sub-advisor, OakBrook Investments, emphasizes or deemphasizes the
stocks in the index based on a quantitative model that monitors investor
expectations for each stock. That approach enhanced the Fund's relative returns
during the period. Stock selection boosted returns against the benchmark,
particularly in the consumer discretionary and financial sectors. Sector
allocation also boosted relative returns slightly. The Fund benefited from an
over-weight position in energy stocks and underweight stakes in
telecommunications and consumer discretionary shares. +


                                       6


The Fund held a modest cash position throughout the period, to manage
shareholder redemptions and capture developing investment opportunities. That
cash stake weighed on returns versus the benchmark, as did trading costs and
fees. Those factors caused the Fund to lag its benchmark by a small margin. +

Our goal is to outperform the S&P 500 Stock Index(1) over multiple market

relatively predictable, above-average 3- to 5-year earnings streams. We
typically purchase stocks of large, high-equality companies with superior
earnings per share growth rates and correspondingly appropriate price/earnings
ratios(2). We consider sales when a stock's relative price/earnings ratio is
well in excess of historical, similar-market norms or when a significant and
ongoing earnings stream deterioration is forecast."

Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 5.33% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 8.15% total return for the Fund's benchmark, the S&P
500 Stock Index. (1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the period ended
January 31, 2005, were -0.48%, -5.88%, -3.62% and 10.70%, respectively, for

Q. What factors affected the Fund's performance during the period?

A. The equity market posted solid gains during the six-month period through
January, boosting the returns of the Fund and giving an even stronger lift to
the broad-market S&P 500.

The Fund has long emphasized large and high-quality growth stocks. That
philosophy muted its performance relative to its benchmark. The disparity
between the Fund's market-capitalization size, and that of its target, weighed
heavily on comparative returns during this period, as smaller and sometimes
riskier stocks significantly outperformed larger-company shares.+

Moreover, our Fund's traditional, long-term and rigorously focused growth style
approach typically leads it to hold larger stakes than its benchmark in both the
health care and the technology sectors. The recent powerful performance of
energy stocks undermined the


                                       8


Fund's relative returns. Our stock selection in the industrials and, to some
extent, the health care sectors also hurt our Fund's relative performance.+

Our consumer discretionary and consumer staples allocations provided a modest
lift against all of the comparative indices. Conversely, our significantly
underweight position in the dramatically outperforming utilities sector hurt
relative performance. Our long-established practice of eschewing the sector
caused the Fund to lose some ground.+

We believe our Fund is well-positioned to compete successfully when large-cap
growth stocks resume market leadership. Until then, we will continue to execute
in the focused, traditional-growth style that historically has provided our
Fund's above-average long term returns. +

INVESTMENT CONCERNS

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGER'S PERSPECTIVE

"As a growth-oriented fund, the Capital Growth Fund focuses on industry leaders
with high earnings per share. We generally look for annual earnings growth of
15% or higher. After identifying strong themes, such as technology or health
care, we select companies that have financial strength, good return on equity,
reasonable debt-to-equity ratios and strong revenue growth. We apply sell
discipline through price targets and downside alerts."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 6.03% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 5.80% total return for the Fund's benchmark, the S&P
500/BARRA Growth Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the period ended
January 31, 2005, were 0.19%, -5.49%, -6.16% and 8.66%, respectively, for Class
A Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder
would pay on distributions and redemptions. The investment return and principal
value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. The stock market posted solid gains during the period, helping the returns of
the Fund and its benchmark. Value stocks led the market, however, creating a
headwind for this growth-oriented Fund.

Stock selection provided the largest benefit to the Fund's performance relative
to its benchmark. On the whole, the stocks in the Fund's portfolio showed
increases in sales and earnings growth and in returns on assets and returns on
equity. Those improvements helped the Fund's performance compared to its index.
In particular, the Fund's holdings in the health care and consumer discretionary
sectors significantly outperformed those sectors in the index. Individual
selections in the consumer staples sector did drag somewhat on relative
returns.+


                                       10


We increased the Fund's stake in mid-capitalization shares during the period.
That change boosted returns against the benchmark, as smaller stocks generally
outperformed larger stocks. We also increased the Fund's emphasis on stocks with
relatively high growth rates and capital gains potential. That strategy reduced
the Fund's exposure to dividend-paying stocks, causing a decrease in yield
pay-outs to the Fund. That said, the more-aggressive strategy helped the Fund
out-gain its benchmark in a rising market. +

This Fund emphasizes long-term earnings growth. As a result we did not increase
the Fund's weightings in the energy or basic materials sectors, since those
sectors showed little long-term earnings growth potential.

+   The Fund's portfolio is current to January 31, 2005 and subject to change.

Janna holds an MA in economics. They have worked together for the past 12 years.

INVESTMENT CONCERNS

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.

Mid-capitalization stocks typically carry additional risk, since smaller
companies generally have higher risk of failure and, historically, their stocks
have experienced a greater degree of volatility.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGER'S PERSPECTIVE

"Our stock selection strategy for the AmSouth Mid Cap Fund is fairly
conservative, with Fund returns having a very close correlation to those of the
S&P Mid Cap 400 Stock Index(1). We try to be 100% invested and do not try to
time the market. Through the use of sophisticated computer model, we attempt to
identify and invest in 320 to 380 stocks within the S&P Mid Cap 400 that are
starting to experience a widening range of investor expectations. We look to
overweight those stocks that we believe may outperform the overall market."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 12.31% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 12.24% total return for the Fund's benchmark, the S&P
MidCap 400 Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and Since Inception (5/4/99) average annual total returns for the
periods ended January 31, 2005, were 6.16%, 4.63%, -5.43% and 4.74%,
respectively, for Class A Shares. The returns quoted assume the reinvestment of
dividends and capital gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and

more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance during the period?

A. Mid-cap stocks posted strong returns during the period. Medium-sized stocks
lost ground during August, but surged from September through December before
slipping back in January. That environment helped the Fund and its benchmark
generate strong gains.

This Fund's sub-advisor, OakBrook Investments, over- or under-weights the stocks
in its benchmark based on a quantitative model that monitors investor
expectations surrounding each stock. That methodology boosted relative returns
during the period. Stock


                                       12


selection added to relative gains, as the Fund's holdings in the information
technology, consumer discretionary and industrials sectors out-performed the
respective sectors in the benchmark. +

Those positive factors were partly offset by the Fund's sector weightings--in
particular an overweight position in energy stocks during the last three months
of the period. Mid-cap energy stocks performed well during the first two months
of the recent period, but subsequently retrenched as energy prices declined. +

Dean McQuiddy serves as portfolio manager for the AmSouth Small Cap Fund. He has
nearly 20 years of experience in investment management and holds a BS in
finance. He created and managed the small-cap growth product at Barnett Capital
Advisors for 11 years.

INVESTMENT CONCERNS

Small capitalization funds typically carry additional risks since smaller
companies generally have a higher risk of failure.

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGER'S PERSPECTIVE

"For the AmSouth Small Cap Fund, we use a disciplined investment process to
identify 60 to 80 fundamentally attractive small companies that share certain
attributes: above-market sales and earnings growth, increasing estimates of
future earnings and reasonable valuations. We aim to buy these companies in the
early stages of their--before their stocks get overvalued in the marketplace."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 12.53% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 13.48% total return for the Fund's benchmark, the
Russell 2000(R) Growth Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and Since Inception (3/3/98) average annual total returns for the
periods ended January 31, 2005, were 6.39%, 4.09%, -2.43% and -0.54%,
respectively, for Class A Shares. The returns quoted assume the reinvestment of
dividends and capital gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder

value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance during the period?

A. Small stocks rallied, helping the Fund and its benchmark post solid gains.
Growth shares lagged value stocks, creating a headwind for this growth-oriented
portfolio.

This Fund's sub-advisor, Sawgrass Asset Management, held a significantly
underweight position in health care stocks: The Fund held an average of 13.5% of
its assets in the health care sector, compared to an average of 21.5% for the
benchmark. That comparatively small stake boosted performance against the index,
as health care stocks lagged the market. Stock selection in the health care
sector also had a modestly beneficial effect on relative returns. +

The managers also under-weighted the technology sector, with an average
allocation of 22%, versus an average allocation of 27% for the benchmark.
Technology stocks trailed the market, so the Fund's smaller stake increased
relative gains. Stock selection in this sector also boosted returns against the
index. Selection among consumer discretionary stocks helped the Fund's relative
performance as well.+


                                       14


Stock selection hurt relative returns in the basic materials sector, as the Fund
did not fully participate in a strong rally by shares of steel and aluminum
producers. The Fund held an overweight stake in energy stocks. That sector
generally posted strong performance, but the Fund's energy holdings did not keep
pace with those in the index. As a result, the Fund's holdings in that sector
weighed on the portfolio's relative performance. +

Similarly, the Fund's overweight position in industrial stocks included some
individual holdings that did not perform as well as the sector, which taken as a
whole posted relatively strong gains. As a result, the Fund's allocation to
industrial stocks hurt the portfolio's returns against the index. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

INVESTMENT CONCERNS

An investment in this Fund entails the special risks of international investing,
including currency exchange fluctuation, government regulations, and the
potential for political and economic instability. The Fund's share price is
expected to be more volatile than that of a U.S.-only fund.

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes.

Value-based investments are subject to the risk that the broad market may not
recognize their intrinsic value.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGER'S PERSPECTIVE

"The AmSouth International Equity Fund is designed to provide diversified
exposure to the international large cap value asset class. The portfolio invest
in large cap stocks with high book values relative to price (value stocks). The
"value" parameter is determined on a country basis. Currently, the Fund
systematically invest in a broadly diversified portfolio of large "value" stocks
in 21 developed-market countries."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 20.47% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 16.68% total return for the Fund's benchmark, the
Morgan Stanley Capital International EAFE(R) (Europe, Australasia and Far East)
Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and Since Inception (8/18/97) average annual total returns for
the periods ended January 31, 2005, were 13.81%, 14.95%, 2.05% and 4.43%,
respectively, for Class A Shares. The returns quoted assume the reinvestment of
dividends and capital gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and

value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. Developed international stock markets generated strong returns during the
period, helping the Fund and the benchmark produce solid gains. The dollar
weakened compared to most foreign currencies. The Fund does not hedge its
exposure to foreign currencies, so dollar weakness increased the Fund's returns.
Strong performance among value and small-cap stocks also boosted the Fund's
absolute performance. +


                                       16


The Fund's sub-advisor, Dimensional Fund Advisors, employs a strict value
methodology to construct a portfolio that is broadly diversified across
geographical regions. The managers rank the stocks in each of the 21 developed
markets represented in the index primarily using book value-to-market
capitalization, and invest in approximately the top 30% of stocks, by number, in
each country. +

That approach helped the Fund outperform its benchmark, since value stocks led
global stock markets during the period. The Fund's value discipline also
typically leads it to hold shares with smaller average market capitalizations
than the average stocks that comprise the Fund's benchmark. That dynamic also
boosted relative returns, as smaller shares outperformed larger stocks for the
six-month period. +

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"The AmSouth Balanced Fund is a diversified fund that offers investors a simple
and easy way to balance their investments between stocks and bonds. Within the
equity component, our diversified equity strategy invests in a broad array of
high quality stocks to provide long term growth. The fixed income component
contains a mix of investment grade bonds to generate income. We assess market
opportunities between the two asset classes and allocate assets in the Fund to
potentially achieve high risk-adjusted returns.
- --------------------------------------------------------------------------------

INVESTMENT CONCERNS

Equity securities (stocks) are more volatile and carry more risk than other
forms of investments, including investments in high-grade fixed income
securities. The net asset value per share of this Fund will fluctuate as the
value of the securities in the portfolio changes. Bonds offer a relatively
stable level of income, although bond prices will fluctuate providing the
potential for principal gain or loss. Intermediate-term, higher-quality bonds
generally offer less risk than longer-term bonds and a lower rate of return.

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 6.26% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). The Fund's benchmarks, the S&P 500 Stock Index(1) and the Lehman
Brothers Government/Credit Bond Index(1), returned 8.15% and 4.02%,
respectively.

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

The Fund held an average of approximately 60% of its assets in stocks and
roughly 40% of its assets in bonds. Stocks significantly outperformed bonds
during the period, so the Fund's emphasis on stocks helped boost returns.

With the maximum sales charge of 5.50% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the periods ended
January 31, 2005, were 0.44%, -1.15%, 5.15% and 8.72%, respectively, for Class A
Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder
would pay on distributions and redemptions. The investment return and principal
value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. Stocks posted solid returns during the period, particularly during the fourth
calendar quarter of 2004. That trend boosted the returns of the Fund's equity
allocation. Yields on long-term bonds declined, while yields on short-term bonds
rose. The Fund's fixed-income portion generated modest gains in that
environment.+


                                       18


We maintained a higher-than-neutral stock allocation throughout the period. The
Fund held 60% of its assets in stocks, compared to its neutral position of 50%.
The emphasis on equities boosted the Fund's returns relative to its neutral
weightings, as stocks significantly outperformed bonds. +

Stock selection helped the Fund's equity allocation outperform the S&P 500.
Selection in the health care sector was especially beneficial: The Fund's health
care stake out-gained the health care stocks in the S&P 500 by approximately
eight percentage points, largely because we avoided or under-weighted several
stocks that suffered very poor returns. The Fund's superior performance in the
health care sector made a significant impact on relative performance, because
health care stocks comprise a sizable portion of the index and this Fund. Stock
selection in the technology sector weighed on the equity allocation's returns
against the stock benchmark, largely due to weak returns among certain hardware
and networking stocks in the Fund's portfolio. +

The Fund's bond allocation lagged its benchmark for the period. We maintained a
short average duration relative to the fixed-income index, to protect against
rising interest rates. That strategy left the Fund underexposed to long-term
bonds, which saw their yields decline and their prices rise. We increased the
Fund's average duration late in the period. +

The bond allocation's returns relative to the fixed-income benchmark benefited
from an emphasis on corporate bonds, which outperformed government credit. The
Fund's high-quality focus prevented it from benefiting from even stronger
performance among lower-quality issues, however. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

The AmSouth Strategic Portfolios are managed by a team of AmSouth investment
managers, including both equity and fixed income specialists. The team has more
than 40 years of combined investment management experience.

INVESTMENT CONCERNS

The Funds invest in underlying funds, so the investment performance is directly
related to the performance of those underlying funds. Before investing in the
Fund, investors should assess the risks associated with and types of investments
made by each of the underlying funds in which the Funds invests.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

The Portfolios seek to provide investors with the potential to achieve a variety
of long- and short-term goals, commersurate with investors' specific time
horizons and tolerance for risk. Each of the four Strategic Portfolios invests
in a combination of underlying mutual funds from the AmSouth fund family. Based
on each Portfolio's asset-allocation target, the mangers periodically rebalance
stock, bond and money market holdings--based on analysis of economic and market
trends.

Q & A

Q. How did the Funds perform during the period?

A. During the six-month period ended January 31, 2005, the Funds' total returns,
benchmark returns and other comparative returns were as follows:

Lipper Multi-Cap Core Funds Average(1): 9.47%

AmSouth Growth Portfolio
(Class A Shares at NAV. Had the effects of the front-end sales charge been

Merrill Lynch Government/Corporate Master Index(1): 3.98%
Lipper Flexible Portfolio Funds Average(1): 7.54%

With the maximum sales charge of 5.50% and recurring fees, the six-month, 1
Year, 5 Year and Since Inceptions average annual total returns for the Class A
Shares for the periods ended January 31, 2005 were 3.87%, 1.11%, -0.53% and
1.60%, respectively, for the Aggressive Growth Portfolio; 2.00%, 0.06%, 0.73%
and 1.61%, respectively, for the Growth Portfolio; 0.88%, -0.81%, 2.21% and
2.44%, respectively, for the Growth and Income Portfolio; and 0.22%, -1.28%,

performance data current to the most recent month end please visit

Q. What factors affected the Portfolios' performance?

A. The stock market staged a strong rally during the fourth quarter of 2004,
helping the Strategic Portfolios generate gains for the six-month period. The
Portfolios' returns benefited from their broad diversification in the stock
market, including funds that invest in various styles and market-cap sizes as
well as international shares.

Above-neutral allocations to stocks throughout the period boosted the
Portfolios' returns. The Aggressive Growth Portfolio held 99% of its assets in
stock during the period, compared to its neutral allocation of 85%. The Growth,
Growth and Income and Moderate Growth and Income Portfolios all held equity
allocations ten percentage points higher than their neutral positions.+

The diversification of the Portfolios' equity holdings helped those equity
stakes outperform the broad market, as measured by the Standard & Poor's 500
Index. In particular, the Portfolios benefited from their allocations to small
and medium-sized stocks, value shares and inter-national equities, all of which
generated strong gains during the six-month period.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"The AmSouth Government Income Fund is more suitable for investors who seek
income but also demand the safety of U.S. government securities. Although we
attempt to consistently generate a high level of income, investors should be
aware that yields and principal values vary and that the Fund is not guaranteed
by the U.S. Government."
- --------------------------------------------------------------------------------

INVESTMENT CONCERNS

U.S. Government guarantees apply only to certain underlying securities of the
Fund's portfolio and not the Fund's shares.

Bonds offer a relatively stable level of income, although bond prices will
fluctuate providing the potential for principal gain or loss. Intermediate-term,
higher-quality bonds generally offer less risk than longer-term bonds and a
lower rate of return.

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 2.00% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 3.53% total return for the Fund's benchmark, the
Lehman Brothers Mortgage Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 4.00% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the periods ended
January 31, 2005, were -2.07%, -1.99%, 5.21% and 5.91%, respectively, for Class
A Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder
would pay on distributions and redemptions. The investment return and principal
value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance during the period?

This Fund invests primarily in mortgage-backed securities. Such issues fared
well during the period, as investors prized their relatively high yields and the
protection they offered against rising interest rates. That environment helped
the Fund and its benchmark post positive returns.

The Fund began the period with 50% of its assets in mortgage-backed securities,
40% in agency issues and 10% in Treasuries. We maintained those allocations
through December. In January we significantly increased the Fund's weighting in
mortgage-backed securities, to 82% of the Fund's assets, in order to take
advantage of the attractive yields and outlook those bonds offered. This Fund's
benchmark is comprised entirely of mortgage-backed securities, so the Fund's
smaller weighting dragged on relative returns as those bonds performed well.
That dynamic was the primary reason that the Fund lagged its benchmark. +


                                       22


The Fund held an average duration that was modestly shorter than the benchmark
throughout the period, to help protect against rising interest rates. That
strategy had a slightly negative impact on returns against the benchmark, as
bonds with longer durations generally performed best. +

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"The AmSouth Limited Term Bond Fund was designed to fill the gap between money
market funds and long-term bond funds. For investors looking for a diversified
bond fund, this Fund represents the first step out on the 'risk/return' spectrum
from the money market arena."
- --------------------------------------------------------------------------------

INVESTMENT CONCERNS

Short- or intermediate-term investment grade bonds offer less risk and generally
a lower rate of return than longer-term higher yielding bonds.

Bonds offer a relatively stable level of income, although bond prices will
fluctuate providing the potential for principal gain or loss. Intermediate-term,
higher-quality bonds generally offer less risk than longer-term bonds and a
lower rate of return.

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 0.55% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 1.22% total return for the Fund's benchmark, the
Merrill Lynch 1-5-Year Government/Corporate Bond Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 2.00% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the periods ended
January 31, 2005, were -3.51%, -3.57%, 4.19% and 5.06%, respectively, for Class
A Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder
would pay on distributions and redemptions. The investment return and principal
value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com

Q. What factors affected the Fund's performance?

The Fund held a shorter average duration than the benchmark throughout the
period, in order to protect against the risk of rising interest rates. That
strategy hurt relative performance during the first three months, as short-term
yields declined. The Fund's relatively short average duration then helped
returns against the bench- mark when yields rose during the second half of the
recent period. The Fund sacrificed some yield to pursue its low-duration
strategy, particularly early in the period when the yield curve was steeper,
with higher yields on longer-term issues+


                                       24


The Fund was overweight corporate bonds during the entire period, which helped
relative returns significantly. One- to five-year corporate bonds returned 43
basis points (0.43%) more than the index for the period as a whole. The
beneficial effect of the Fund's overweight position in corporate bonds was
tempered somewhat by the overall superior credit quality of the Fund, as lower
rated corporate bonds were by far the best performers. +

We further increased the Fund's overweight position in corporate bonds during
the period. The Fund held 53% of its assets in corporate issues as of August 1,
2004, compared to 60% by the end of the period. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

higher-quality bonds generally offer less risk than longer-term bonds and a

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"The AmSouth High Quality Bond Fund seeks to take advantage of changes in
interest rates to pursue strong returns. We buy longer bonds when interest rates
are high and expected to fall, and shorter bonds when interest rates are low and
expected to rise. The change in the average maturity or duration is one of the
most powerful determinants of return. Through the active use of high-quality
investments, we strive to obtain excellent returns."
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 2.94% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). That compared to a 4.02% total return for the Fund's benchmark, the
Lehman Brothers Government/Credit Bond Index.(1)

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 4.00% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the periods ended
January 31, 2005, were -1.16%, -1.30%, 6.31% and 6.54%, respectively, for Class
A Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted

value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance?

A. Yields on short-term bonds rose during the period, while yields on
longer-term bonds declined. The decline in long-term bond yields helped the Fund
produce positive returns. The Fund benefited from its position in corporate
issues, which outperformed Treasury bonds. +

The Fund held an average duration shorter than that of the benchmark throughout
the period. We established and maintained that position to protect against a
rise in interest rates. That strategy left the Fund underexposed to long-term
bonds, so the relative strength of those securities weighed on returns versus
the benchmark. +

We lengthened the Fund's duration late in the period to benefit from any further
flattening of the yield curve--that is, any further decline in long-term rates
relative to short-term rates. That strategy boosted the Fund's relative returns
during January. The Fund


                                       26


began the recent six-month period with an average duration of 4.61 years, and
ended the period with an average duration of 5.05 years.+

The Fund held an overweight position in corporate bonds throughout the period.
That helped relative returns, as corporate bonds significantly outperformed
government-issued securities. The Fund's high-quality focus prevented it from
benefiting from even stronger performance among lower-quality corporate bonds,
which resulted in the Fund lagging its benchmark. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' PERSPECTIVE

"With the AmSouth High Quality Municipal Bond Fund, we concentrate on
high-quality municipal bonds--those in the top three rating classes, or of
comparable quality. As with other AmSouth bond funds, we strive to achieve
strong returns by taking advantage of anticipated changes in interest rates."
- --------------------------------------------------------------------------------

INVESTMENT CONCERNS

The Fund's income may be subject to certain state and local taxes and, depending
on your tax status, the federal alternative minimum tax.

Bond funds will tend to experience smaller fluctuations in value than stock
funds. However, investors in any bond fund should anticipate fluctuations in
price, especially for longer-term issues and in environments of rising interest
rates.

- --------------------------------------------------------------------------------
Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 2.01% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower) during the period. In comparison, the Fund's benchmark the Merrill Lynch
1-12-Year Municipal Bond Index(1) returned 3.46%.

The Fund's total return does not reflect the deduction of a sales charge on
Class A Shares. If reflected, the sales charge would reduce the performance
quoted.

With the maximum sales charge of 4.00% and recurring fees, the Fund's six month,
1 Year, 5 Year and 10 Year average annual total returns for the periods ended
January 31, 2005, were -2.10%, -2.59%, 4.57% and 4.49%, respectively, for Class
A Shares. The returns quoted assume the reinvestment of dividends and capital
gains distributions.

Past performance does not guarantee future results. The performance data quoted
represents past performance and current returns may be lower or higher. Total
return figures include change in share price, reinvestment of dividends and
capital gains and does not reflect the deduction of taxes that a shareholder

value will fluctuate so that an investor's shares, when redeemed may be worth
more or less than the original cost. For performance data current to the most
recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund during the period?

A. Yields on long-term municipal bonds declined, while yields on short-term
municipal bonds rose. Yields on the four- to five-year securities which we
overweighted declined only slightly, so capital appreciation contributed
relatively little to Fund gains. Instead, bond yields generated most of the
Fund's positive returns. +

The Fund held a shorter average duration than that of the benchmark throughout
the period, in order to protect against rising interest rates. That approach
weighed on relative returns, since it prevented the Fund from holding many of
the longer-term issues that


                                       28


performed the best. We lengthened the Fund's average duration late in the period
in order to obtain additional yield for shareholders. The Fund held an average
duration of 3.91 years as of August 1, 2004, and ended the period on January 31,
2005 with an average duration of 4.80 years. +

The Fund held bonds with very high credit quality, in keeping with its
high-quality mandate. That had a mildly negative effect on returns against the
benchmark, as lower-quality bonds led the market. +

A. The market for Florida municipal debt was similar to the national municipal
market: Yields on long-term municipal bonds fell, while yields on short-term
issues rose. This Fund over-weighted securities with durations of between four
and five years. Yields on those issues declined only slightly, so capital
appreciation was not a major factor in producing Fund returns. +

We maintained a shorter average duration than that of the Fund's benchmark
throughout the period, to protect against the potential for rising interest
rates. That strategy prevented the Fund from holding many of the longer-term
issues that performed the best during the period, hurting the Fund's returns
relative to the index. We lengthened the Fund's average duration late in the
period in order to capture additional yield. The Fund's holdings had an average
duration of 3.86 years as of August 1, 2004, and an average duration of 4.63
years as of January 31, 2005. +

Q & A

Q. How did the Fund perform during the six-month period ended January 31, 2005?

A. The Fund delivered a total return of 1.59% (Class A Shares at NAV. Had the
effects of the front-end sales charge been included, the return would have been
lower). The Fund's benchmark, the Merrill Lynch 1-12-Year Municipal Bond
Index(1), returned 3.46%.

recent month end please visit www.amsouthfunds.com.

Q. What factors affected the Fund's performance during the period?

A. Tennessee municipal bonds generally performed in line with other states'
municipal bonds during this period, as yields fell on the long end of the yield
curve and rose on the short end. The Fund over-weighted securities with
durations between four and five years. Yields in that section of the curve
declined only modestly, so the yields produced by the Fund's portfolio were a
major factor in generating returns.+


                                       32


We maintained a relatively short average duration throughout the period, to
protect shareholders' capital in case interest rates increased. The Fund held
few of the long-term issues that led the market, so the strategy dragged on
relative returns for the period as a whole. We lengthened the Fund's average
duration late in the period in order to capture additional yield. The Fund's
portfolio held securities with an average duration of 3.75 years as of August 1,
2004, and an average duration of 4.39 years as of January 31, 2005. +

This Fund's mandate calls for it to maintain a portfolio with high credit
quality. High-quality bonds lagged lower-quality issues during this period, so
the Fund's emphasis on high-quality securities dragged modestly on relative
returns. +

+ The Fund's portfolio is current to January 31, 2005 and subject to change.

INVESTMENT CONCERNS

Investments in the Prime, the Treasury Reserve, the Tax-Exempt, and the
Institutional Prime Obligations Money Market Funds are neither insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Funds seek to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Funds.

The AmSouth Tax Exempt Money Market Fund's income may be subject to certain
state and local taxes and, depending on one's tax status, the federal
alternative minimum tax.

- --------------------------------------------------------------------------------
Q & A

Q. What factors affected the Funds' performance during the six-month period
ended January 31, 2005?

A. The Federal Reserve Board raised its target short-term interest rate four
times, for a total increase of one percentage point. Those increases pushed up
yields on short-term debt. Rising short-term yields allowed the Funds to capture
additional yield for shareholders as the period progressed.

The Funds' investments had average maturities shorter than those of their
benchmarks throughout the period. That strategy provided the flexibility to
invest in higher-yielding securities as rates rose, while protecting
shareholders' capital. The Funds' relatively short average maturities boosted
performance against their benchmarks. +

These Funds, except for the Tax-Exempt Money Market Fund, focus on high-quality
fixed- and variable-rate securities. A limited supply of high-quality commercial
paper prevented the Funds from adding multiple new commercial paper names to the
portfolios. The Funds found opportunities in overnight repurchase agreements,
which adjust their yields on a day-to-day basis and therefore reflected changes
in Federal Reserve policy. The Tax-Exempt Money Market Fund emphasized
variable-rate securities, which benefited from the rising-rate environment. +

Pioneer America Income Trust

PRO FORMA NOTES TO COMBINING FINANCIAL STATEMENTS
12/31/04
(Unaudited)

1.   Description of the Trust

Pioneer America Income Trust (the Trust), is a Massachusetts statutory trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Trust is to
provide a high level of current income consistent with preservation of capital
and prudent investment risk.

The Trustees have authorized the issuance of five classes of shares of the
Trust. After the merger, the Trust will offer six classes of shares - Class A,
Class B, Class C, Investor Class, Class R and Class Y shares. Class Y shares are
being offered as part of the acquisition. Class R shares were first publicly
offered on April 1, 2003. Investor Class shares were first publicly offered on
December 10, 2004. The Trust is not offering additional Investor Class shares
except in connection with the reinvestment of dividends on the Trust's
outstanding Investor Class shares. Each class of shares represents an interest
in the same portfolio of investments of the Trust and have equal rights to
voting, redemptions, dividends and liquidations, except that each class of
shares can bear different transfer agent and distribution fees and has exclusive
voting rights with respect to the distribution plans that have been adopted by
Class A, Class B, Class C, and Class R shareowners, respectively. There is no
distribution plan for Class Y shares and Investor Class shares.

2.   Basis of Combination

The accompanying pro forma combining financial statements, and related notes,
are presented to show the effect of the proposed acquisition (the "acquisition")
of AmSouth Government Income Fund by the Trust, as if such acquisition had taken
place as of January 1, 2004.

Under the terms of an Agreement and Plan of Reorganization (the
"Reorganization") between these two Trusts, the combination of the Trust and
AmSouth Government Income Fund will be treated as a tax-free business
combination and accordingly will be accounted for by a method of accounting for



tax-free mergers of investment companies. The acquisition will be accomplished
by an acquisition of the net assets of AmSouth Government Income Fund in
exchange for shares of the Trust at their net asset values. The accompanying
schedules of investments, statements of assets and liabilities and the related
statements of operations of the Trust and AmSouth Government Income Fund have
been combined as of and for the most recent fiscal year ended December 31, 2004.
Following the acquisition, the Trust will be the accounting survivor. All
related acquisition costs will be borne by the Advisors.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of the Trust and AmSouth Government
Income Fund included in their annual reports to shareowners dated December 31,
2004 and July 31, 2004, respectively. Adjustments have been made to expenses for
Pioneer affiliate contractual rates and duplicate services that would not have
been incurred if the merger took place on January 1, 2004.

3.   Security Valuation

Security transactions are recorded as of trade date. Securities are valued at
prices supplied by independent pricing services, which consider such factors as
Treasury spreads, yields, maturities and ratings. Valuations may be supplemented
by dealers and other sources, as required. Securities for which market
quotations are not readily available are valued at their fair values as
determined by, or under the direction of the Board of Trustees. Principal
amounts of mortgage-backed securities are adjusted for monthly paydowns.
Premiums and discounts related to certain mortgage-backed securities are
amortized or accreted in proportion to the underlying monthly paydowns.
Securities for which there are no other readily available valuation methods are
valued at their fair values as determined by, or under the direction of the
Board of Trustees. As of December 31, 2004, there were no securities fair
valued. All discounts/premiums on debt securities are accreted/amortized for
financial reporting purposes. Interest income is recorded on the accrual basis.
Temporary cash investments are valued at amortized cost.

4.   Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Trust that would have been issued at December 31, 2004, in connection with the
proposed acquisition. The number



of shares assumed to be issued is equal to the net asset value of shares of
AmSouth Government Income Fund, as of December 31, 2004, divided by the net
asset value per share of the Trust's shares as of December 31, 2004. The pro
forma number of shares outstanding, by class, for the combined Trust consists of
the following at December 31, 2004:



- --------------------------------------------------------------------------------------

                         Shares of           Additional Shares       Total Outstanding

Class Y               0                      18,802                  18,802

- --------------------------------------------------------------------------------------


5.   Federal Income Taxes

     Each Trust has elected to be taxed as a "regulated investment company"
     under the Internal Revenue Code. After the acquisition, it will continue to
     be the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The identified cost of investments for these Trusts is substantially the
     same for both financial and federal income tax purposes. The cost of
     investments will remain unchanged for the combined Trust.

ITEM 17. UNDERTAKINGS.

(1)      The undersigned Registrant agrees that prior to any public reoffering
of the securities registered through the use of a prospectus which is part of
this Registration Statement by any person or party which is deemed to be an
